The microphone is provided with an atmospheric pressure sensing surface and a negative pressure sensing surface. The atmospheric pressure sensing surface is configured to sense atmospheric pressure, and the negative pressure sensing surface is configured to sense negative pressure in an airflow path. In a process of vertically placing the electronic vaporization device, external airflow moves toward a side of an air outlet. An angle between a normal direction of the negative pressure sensing surface of the microphone and an air outlet direction of the air outlet is an obtuse angle, that is, the microphone is inverted. The negative pressure sensing surface is located on the side of the microphone facing away from the air outlet, and the atmospheric pressure sensing surface is located on the side of the microphone close to the air outlet, that is, located on the leeward side of the microphone.

Referring to FIG. 1 and FIG. 2, an electronic vaporization device 100 provided in an embodiment includes a vaporization assembly 1 and a replacement assembly 2. The electronic vaporization device 100 may be configured to contain a vaporization substrate, for example, a medical liquid, an e-liquid or another liquid substrate, or a semi-solid substrate, and vaporize the vaporization substrate to generate an aerosol for a user to inhale.
The vaporization assembly 1 includes a vaporization holder 11 and a vaporization core 12. An accommodating groove 11b and an assembly groove 11a are formed in the vaporization holder 11. The accommodating groove 11b can store the vaporization substrate and supply the vaporization substrate to the vaporization core 12, and the vaporization substrate guided into the vaporization core 12 through the accommodating groove 11b can be vaporized by the vaporization core 12 into an aerosol. The assembly groove 11a is configured to assemble the replacement assembly 2.
The replacement assembly 2 is detachably connected to the vaporization assembly 1, and is configured to supply the vaporization substrate to the accommodating groove 11b. In an embodiment, an additional replenishment chamber 21a may be disposed in the replacement assembly 2 according to a requirement of a user. After the replacement assembly 2 is assembled into the assembly groove 11a, the replenishment chamber 21a is in communication with the accommodating groove 11b, to continuously supply the vaporization substrate to the accommodating groove 11b. Part of the replacement assembly 2 may be accommodated in the assembly groove 11a. A manner of accommodating the replacement assembly 2 and the assembly groove 11a is not limited. For example, in an embodiment, a first magnetic attraction surface is formed on the replacement assembly 2, the assembly groove 11a is provided with a second magnetic attraction surface, and the first magnetic attraction surface is in magnetic cooperation with the second magnetic attraction surface. In another embodiment, the assembly groove 11a is a groove provided with a fitting port, and the replacement assembly 2 is accommodated in the assembly groove 11a through the fitting port and is hermetically connected to the vaporization assembly 1.
According to the foregoing electronic vaporization device 100, because the accommodating groove 11b configured to store the vaporization substrate and the assembly groove 11a configured to assemble the replacement assembly 2 are provided in the vaporization holder 11 of the vaporization assembly 1, compared with an existing electronic vaporization device with only one liquid storage tank, the replacement assembly 2 may have a sealing function for the assembly groove 11a when liquid supply is not required. Therefore, the vaporization substrate is unlikely to leak out during transportation.
In an embodiment, referring to FIG. 2 and FIG. 3, the vaporization assembly 1 further includes a vaporization base 13 disposed in the accommodating groove 11b. An aerosol guide channel 13a and a liquid supply port 13b are formed in the vaporization base 13. The vaporization core 12 is disposed in the aerosol guide channel 13a of the vaporization base 13, and the liquid supply port 13b is in communication with the accommodating groove 11b and the vaporization core 12. The replacement assembly 2 is provided with an aerosol outlet channel 211a and a suction nozzle opening 211b in communication with an end of the aerosol outlet channel 211a. The aerosol guide channel 13a is in communication with the aerosol outlet channel 211a. In this embodiment, the vaporization base 13 is a hollow tubular structure extending vertically, the aerosol guide channel 13a is a hollow region in the vaporization base 13, and the liquid supply port 13b is a circular through hole provided in the side wall of the vaporization base 13. The upper end of the aerosol guide channel 13a is in communication with the lower end of the aerosol outlet channel 211a. After the vaporization substrate in the accommodating groove 11b is vaporized by the vaporization core 12 into an aerosol, the aerosol may flow around the vaporization core 12 into the aerosol guide channel 13a, and then flow out through the aerosol outlet channel 211a and the suction nozzle opening 211b for a user to inhale. In this embodiment, the vaporization core 12 is a hollow mesh structure. In another embodiment, the vaporization core 12 may alternatively be a plate-shaped structure. In this case, the structure of the vaporization base 13 may be adaptively adjusted with the structure of the vaporization core 12, for example, may also be a plate-shaped structure.
A vaporization manner of the vaporization core 12 is not limited, and includes, but is not limited to, ultrasonic vaporization, vibration vaporization, and thermal vaporization. In an embodiment, referring to FIG. 2 and FIG. 3, the vaporization core 12 includes a heating element 121 and a liquid guide body 122 covering the heating element 121. The liquid guide body 122 is configured to draw the vaporization substrate from the liquid supply port 13b and conduct the vaporization substrate to the heating element 121. The material of the liquid guide body 122 includes, but is not limited to, cotton, a porous ceramic body, a fiber string, and another porous material. The vaporization assembly 1 further includes an electrode 14 electrically connected to the heating element 121. After the electrode 14 is energized, the heating element 121 can generate heat for the vaporization substrate in the liquid guide body 122 to be vaporized into an aerosol.
In an embodiment, a cotton core configured to store the vaporization substrate is disposed in the accommodating groove 11b, and the cotton core can supply the vaporization substrate to the liquid guide body 122. The cotton core has an optimal effect of absorbing the vaporization substrate, and the vaporization substrate is unlikely to leak out during transportation or abnormal reversing of the electronic vaporization device 100.
In an embodiment, referring to FIG. 2, the replacement assembly 2 includes a jacket 21, and the assembly groove 11a is configured to detachably accommodate the jacket 21 of the replacement assembly 2. That is, the jacket 21 can be assembled into or disassembled from the assembly groove 11a according to an actual requirement of a user. In an embodiment, the jacket 21 includes an inner ring shell 211 and an outer ring shell 212, and the outer ring shell 212 is located at the outer periphery of the inner ring shell 211. The outer ring shell 212 is connected to the vaporization holder 11, and the end of the outer ring shell 212 away from the accommodating groove 11b is connected to an end of the inner ring shell 211 away from the accommodating groove 11b. The aerosol outlet channel 211a and the suction nozzle opening 211b are formed in the inner ring shell 211. Specifically, as shown in FIG. 2, the outer ring shell 212 and the inner ring shell 211 are both hollow cylindrical structures extending in an up-down direction. The outer peripheral wall of the lower portion of the outer ring shell 212 is hermetically accommodated in the assembly groove 11a. The upper end of the inner ring shell 211 is smoothly connected to the upper end of the outer ring shell 212. the inner peripheral wall of the inner ring shell 211 surrounds to form the aerosol channel 211a. An opening at the upper end of the inner ring shell 211 is the suction nozzle opening 211b, and the lower end of the inner ring shell 211 is sleeved to the vaporization base 13 for the aerosol outlet channel 211a to be in communication with the aerosol guide channel 13a.
That is, compared with a solid jacket, the jacket 21 in this embodiment is a double-layer annular structure including the inner ring shell 211 and the outer ring shell 212, and is more lightweight. In addition, a hollow region is provided between the inner ring shell 211 and the outer ring shell 212, and can provide a thermal insulation function, so that the risk that a user is scalded due to an excessively high temperature when the aerosol flows through the aerosol outlet channel 211a of the jacket 21 can be effectively reduced, thereby improving user experience.
Structural shapes of the inner ring shell 211 and the outer ring shell 212 include, but are not limited to, annular cylindrical structures such as an annular ring housing, an elliptical ring housing, and a square ring housing. The inner ring shell 211 and the outer ring shell 212 are an integrally formed member. In this way, the jacket 21 has high structural strength.
It may be understood that when the aerosol outlet channel 211a of the electronic vaporization device 100 is not disposed in the replacement assembly 2, the replacement assembly 2 may be merely used as a sealing structure for sealing the assembly groove 11a, for example, merely a cover that is hermetically sleeved in the assembly groove 11a.
In an embodiment, referring to FIG. 2 and FIG. 3, the vaporization holder 11 includes an annular sleeve 111 open at two ends and a partition plate 112 located in the annular sleeve 111. A thickness direction of the partition plate 112 is the same as the up-down direction, and a surface (that is, an upper surface) of one side of the partition plate 112 in the thickness direction and the inner peripheral wall of the annular sleeve 111 enclose to form the assembly groove 11a open at the upper end. A surface (that is, a lower surface) of the other side of the partition plate 112 in the thickness direction and the inner peripheral wall of the annular sleeve 111 enclose to form the accommodating groove 11b provided open at the lower end. A through hole 112a is opened in the partition plate 112, and an end of the aerosol guide channel 13a is in communication with the aerosol outlet channel 211a through the through hole 112a. In an embodiment, the annular sleeve 111 and the partition plate 112 are an integrally formed member. In this way, the vaporization holder 11 has high structural strength.
An end of the inner ring shell 211 is hermetically sleeved to the vaporization base 13. A sleeving manner between the inner ring shell 211 and the vaporization base 13 is not specifically limited. The inner ring shell 211 may be sleeved inside the vaporization base 13, or the vaporization base 13 may be sleeved inside the inner ring shell 211. Referring to FIG. 3, the replacement assembly 2 further includes a sealing jacket 22, and the sealing jacket 22 is sandwiched between the inner ring shell 211 and the vaporization base 13. The sealing jacket 22 is approximately annular. The lower end of the inner ring shell 211 extends into the vaporization base 13 through the through hole 112a of the partition plate 112. The sealing jacket 22 is sleeved between the outer peripheral wall of the inner ring shell 211 and the inner peripheral wall of the outer ring shell 212. The material of the sealing jacket 22 is not specifically limited, and includes, but is not limited to, a flexible sealing material, for example, rubber or silicone, that has an optimal sealing effect and has particular elasticity. Because the sealing jacket 22 is sandwiched between the inner ring shell 211 and the vaporization base 13, the sealing property of joining and communication between the aerosol guide channel 13a and the aerosol outlet channel 211a can be ensured. Therefore, all of the aerosol formed through vaporization by the vaporization core 12 flows from the aerosol guide channel 13a into the aerosol outlet channel 211a, and then flows out from the suction nozzle opening 211b, thereby avoiding a waste caused by leakage of the aerosol from another position.
In an embodiment, referring to FIG. 3, the replacement assembly 2 further includes a sealing ring 25. The sealing ring 25 is sandwiched between the outer peripheral wall of the jacket 21 and the inner peripheral wall of the assembly groove 11a. Specifically, the sealing ring 25 is an annular ring sleeved between the outer peripheral wall of the outer ring shell 212 and the inner peripheral wall of the annular sleeve 111, to provide sealing between the outer peripheral wall of the outer ring shell 212 and the inner peripheral wall of the annular sleeve 111. The material of the sealing ring 25 is not specifically limited, and includes, but is not limited to, a flexible sealing material, for example, rubber or silicone, that has an optimal sealing effect and has particular elasticity. In this embodiment, to facilitate assembly of the sealing ring 25 on the jacket 21, a positioning groove 212a is formed in the outer peripheral wall of the outer ring shell 212. The positioning groove 212a is an annular groove that is adapted to the shape of the sealing ring 25 and that is at the opening of the annular sleeve 111. The sealing ring 25 is disposed in the positioning groove 212a.
In an embodiment, referring to FIG. 2 and FIG. 3, the replenishment chamber 21a is formed between the inner ring shell 211 and the outer ring shell 212. Specifically, the outer peripheral wall of the inner ring shell 211 and the inner peripheral wall of the outer ring shell 212 enclose jointly to form the replenishment chamber 21a. The electronic vaporization device 100 further includes a conduction structure 3 disposed on the vaporization holder 11 or the replacement assembly 2. The replenishment chamber 21a can be in communication with the accommodating groove 11b through the conduction structure 3. As shown in FIG. 3, in this embodiment, the conduction structure 3 is disposed on the partition plate 112, and the conduction structure 3 can implement conduction between the replenishment chamber 21a and the accommodating groove 11b under certain conditions.
In the related art, the liquid storage tank of the electronic vaporization device 100 has a limited liquid storage volume space. If the liquid storage tank uses a cotton core to store the liquid, the cotton core has a volume, and consequently, the amount of liquid released from the liquid storage tank is reduced to some extent. In addition, to avoid liquid leakage from the cotton core, the saturation of the liquid storage in the cotton core cannot reach 100%, resulting in a small liquid storage amount of the entire liquid storage tank. In addition, when the amount of liquid stored in the cotton core has 20% left, attenuation of vaporization consistency of the vaporization substrate is large, and a scorch smell is generated. Therefore, in an existing electronic vaporization device, when a liquid storage tank has a limited space, a use time is short and the number of puffs is small, and the utilization rate of the vaporization substrate is not high. In this embodiment, the replenishment chamber 21a that can contain the vaporization substrate is disposed in the jacket 21, and the vaporization substrate in the replenishment chamber 21a can flow into the accommodating groove 11b through the conduction structure 3. When the accommodating groove 11b has a limited space, the jacket 21 with the replenishment chamber 21a can continuously supply the liquid to the accommodating groove 11b, and can ensure the saturation of the cotton core in the accommodating groove 11b all the time. The vaporization consistency of the electronic vaporization device 100 does not attenuate, so that the use time of the electronic vaporization device 100 is longer, and the number of puffs is larger, thereby improving the utilization rate of the electronic vaporization device 100. In addition, when the vaporization substrate in the accommodating groove 11b is about to be used up, the vaporization substrate is injected into the replenishment chamber 21a, so that the vaporization substrate in the replenishment chamber 21a is kept from contacting the vaporization core 12 prematurely, thereby ensuring the freshness of the vaporization substrate in the replenishment chamber 21a, and improving the quality of the aerosol generated through vaporization. In addition, the replacement assembly storing the vaporization substrate in the replenishment chamber 21a may alternatively be directly used for replenishment after the vaporization substrate in the accommodating groove 11b is used up, and the vaporization core 12 can be repeatedly used. A storage form of the vaporization substrate in the replenishment chamber 21a is not specifically limited. In an embodiment, a cotton core is disposed in the replenishment chamber 21a, and the vaporization substrate is stored in the cotton core. The cotton core has a good effect of absorbing the vaporization substrate, and therefore the vaporization substrate is unlikely to leak out. In another embodiment, the cotton core may alternatively be omitted, that is, the vaporization substrate is directly stored in the replenishment chamber 21a. With this arrangement, the liquid storage amount of the replenishment chamber 21a is large, the use time of the electronic vaporization device 100 is longer, and the number of puffs is larger.
The structure of the conduction structure 3 is not specifically limited. In an embodiment, the conduction structure 3 is a regulating valve. The regulating valve can adjust, based on the remaining amount of liquid stored in the accommodating groove 11b, the amount of feeding the liquid into the accommodating groove 11b by the replenishment chamber 21a, thereby implementing continuous liquid supply to the accommodating groove 11b.
In an embodiment, the conduction structure 3 is a unidirectional pump that can allow only the vaporization substrate in the replenishment chamber 21a to flow into the accommodating groove 11b. The volume of the replenishment chamber 21a is compressed, the unidirectional pump is started, and the vaporization substrate in the replenishment chamber 21a is guided into the accommodating groove 11b through the unidirectional pump, thereby implementing continuous liquid supply to the accommodating groove 11b.
In an embodiment, the conduction structure 3 is a consumable member that separates the replenishment chamber 21a and the accommodating groove 11b. The consumable member may undergo a phase change under certain physical conditions for the replenishment chamber 21a to be in communication with the accommodating groove 11b. For example, the consumable member is a thermofusible medium. For example, the consumable member is a gel. The gel is solid at room temperature, for example, 25°C, and liquefies after the gel is heated to a melting temperature, for example, 50°C to 70°C, for the replenishment chamber 21a to be in communication with the accommodating groove 11b.
Referring to FIG. 4 and FIG. 5, the structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 shown in FIG. 2 and FIG. 3. A difference lies in that the replacement assembly 2 includes a sealing cover 23 covering an opening of the replenishment chamber 21a. The conduction structure 3 includes a piercing member 31 disposed on the partition plate 112. In a process of mounting the replacement assembly 2 into the assembly groove 11a from top to bottom, the piercing member 31 can abut against the sealing cover 23 and pierce the sealing cover 23, so that the vaporization substrate in the replenishment chamber 21a can flow into the accommodating groove 11b through a flow guide channel 31c, thereby implementing continuous liquid supply to the accommodating groove 11b.
Specifically, referring to FIG. 5, the sealing cover 23 includes an outer ring jacket 231, an inner ring jacket 232, and an annular cover plate 233 connected between the inner ring jacket 232 and the outer ring jacket 231. The outer ring jacket 231 is located at the outer periphery of the inner ring jacket 232, and the outer ring jacket 231 is hermetically sleeved over the outer ring shell 212.
In an embodiment, referring to FIG. 5 and FIG. 19, an externally protruding pin 2121 is formed on the outer peripheral wall of the outer ring shell 212, a socket 231a is opened in the outer ring jacket 231, and the pin 2121 is in snap fit with the socket 231a. In this way, it can be ensured that the sealing cover 23 does not fall off the outer ring shell 212, and sealing reliability is high.
The inner ring jacket 232 is sandwiched between the inner ring shell 211 and the partition plate 112. In an embodiment, referring to FIG. 5, a step surface 211d facing the partition plate 112 is formed on the outer peripheral wall of the inner ring shell 211, one end of the inner ring jacket 232 abuts against the step surface 211d, and the other end of the inner ring jacket 232 is sandwiched between the outer peripheral wall of the inner ring shell 211 and a peripheral side wall of the vaporization base 13. The step surface 211d can facilitate mounting and fixing of the inner ring jacket 232.
The piercing member 31 can pierce the annular cover plate 233 to implement continuous liquid supply from the replenishment chamber 21a to the accommodating groove 11b.
In an embodiment, the outer ring jacket 231, the inner ring jacket 232, and the annular cover plate 233 are an integrally formed member, so that the sealing cover 23 has optimal overall sealing performance. It may be understood that, in another embodiment, the outer ring jacket 231 may be sleeved to an inner side of the outer ring shell 212 or may be sleeved to an outer side of the outer ring shell 212. Similarly, the inner ring jacket 232 may be sleeved to an inner side of the inner ring shell 211 or may be sleeved to an outer side of the inner ring shell 211.
The material of the sealing cover 23 includes, but is not limited to, a flexible sealing material, for example, rubber or silicone, that has an optimal sealing effect and has particular elasticity. In this way, on one hand, the sealing cover 23 can achieve sealing for the replenishment chamber 21a, and on the other hand, can also achieve sealing for the assembly groove 11a, so that the number of structural members of the replacement assembly 2 can be reduced, thereby reducing the assembly difficulty of the replacement assembly 2.
Referring to FIG. 3, a piercing port 31a, a flow outlet 31b, and a flow guide channel 31c are formed in the piercing member 31. The flow outlet 31b is in communication with the accommodating groove 11b, and the flow guide channel 31c is in communication with the piercing port 31a and the flow outlet 31b. Referring to FIG. 5, a portion of the annular cover plate 233 corresponding to the piercing port 31a has a small thickness. In a process of mounting the replacement assembly 2 from top to bottom into the assembly groove 11a, the piercing member 31 can abut against the portion of the annular cover plate 233 that has a small thickness, and cause the portion to separate from another portion of the annular cover plate 233 for the replenishment chamber 21a to be in communication with the accommodating groove 11b. For example, as shown in FIG. 3, the piercing member 31 is a syringe structure extending in the up-down direction. The upper end of the piercing member 31 is a piercing port 31a, the lower end of the piercing member 31 is the flow outlet 31b, and the interior of the syringe structure is the flow guide channel 31c.
In this embodiment, the piercing member 31 and the partition plate 112 are integrally formed. In this way, the piercing member 31 is reliably connected and has high structural strength. It may be understood that, in another embodiment, the piercing member 31 may alternatively be disposed on the sealing cover 23 of the replacement assembly 2. In a process of mounting the replacement assembly 2 into the assembly groove 11a from top to bottom, the piercing member 31 can pierce the partition plate 112, and can also enable the vaporization substrate in the replenishment chamber 21a to flow into the accommodating groove 11b through the flow guide channel 31c, thereby implementing continuous liquid supply to the accommodating groove 11b. Certainly, in another embodiment, each of the partition plate 112 and the sealing cover 23 may alternatively be provided with the piercing member 31. In a process mounting the replacement assembly 2 into the assembly groove 11a from top to bottom, the piercing members 31 can simultaneously pierce the sealing cover 23 and the partition plate 112, to implement continuous liquid supply from the replenishment chamber 21a to the accommodating groove 11b.
In an embodiment, referring to FIG. 3 and FIG. 5, the conduction structure 3 further includes a liquid guide member 4 disposed in the flow guide channel 31c to adjust a liquid guide speed. Specifically, the liquid guide member 4 includes, but is not limited to, cotton, a porous ceramic body, a fiber string, and another porous material. The liquid supply rate of the replenishment chamber 21a can be adjusted by adjusting the porosity of the liquid guide member 4. In addition, the liquid guide member 4 may further prevent the liquid substrate in the accommodating groove 11b from being leaking out during disassembly of the replacement assembly 2.
Referring to FIG. 6 to FIG. 8, a structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 shown in FIG. 4 and FIG. 5. A difference lies in that the replacement assembly 2 further includes a wrapping member 24.
Referring to FIG. 7, the wrapping member 24 wraps a side of the annular cover plate 233 away from the replenishment chamber 21a and the outer peripheral side of the outer ring jacket 231. Specifically, the wrapping member 24 wraps the lower end surface of the annular cover plate 233 and the outer peripheral wall of the outer ring jacket 231. At least one avoidance hole is formed in the wrapping member 24, and is configured to avoid interference when the replacement assembly 2 is mounted in the assembly groove 11a. In this embodiment, the at least one avoidance hole includes a first avoidance hole corresponding to the piercing member 31, a second avoidance hole corresponding to a part in which the inner ring jacket 232 extends into the vaporization base 13, and a third avoidance hole corresponding to the pin 2121 of the outer ring shell 212.
The wrapping member 24 can constrain and fix the connection between the sealing cover 23 and the jacket 21. The material of the wrapping member 24 is not specifically limited. For example, the wrapping member 24 may have a steel plate cold common (SPCC) structure, thereby improving the fixing and wrapping effects of the sealing cover 23.
In an embodiment, referring to FIG. 7 and FIG. 8, a ventilation channel 211c that establishes communication between the replenishment chamber 21a and the aerosol guide channel 13a is formed in the replacement assembly 2. In a process of continuously supplying the vaporization substrate to the accommodating groove 11b by the replenishment chamber 21a, the vaporization substrate in the replenishment chamber 21a gradually decreases, and the ventilation channel 211c can supplement air in the aerosol guide channel 13a into the replenishment chamber 21a, so that the air pressure in the replenishment chamber 21a is balanced with the external air pressure, thereby ensuring that the vaporization substrate in the replenishment chamber 21a can be smoothly guided into the accommodating groove 11b.
The position of the ventilation channel 211c is not specifically limited. The ventilation channel 211c may be a channel located inside the inner ring shell 211 or the sealing cover 23, or may be a channel-shaped structure located in the outer peripheral wall of the inner ring shell 211 or the sealing cover 23. For example, in an embodiment, referring to FIG. 8, the ventilation channel 211c is a ventilation groove formed by recessing a partial region of the outer peripheral wall of the inner ring shell 211. Through such an arrangement, a forming process of the ventilation channel 211c is relatively simpler. Specifically, the ventilation groove is formed at the portion of the outer peripheral wall of the inner ring shell 211 that is sleeved with the inner ring jacket 232. An opening of the ventilation groove faces the inner peripheral wall of the inner ring jacket 232. The ventilation groove includes a first slot segment 211ca that extends in the up-down direction and a second slot segment 211cb that extends in a direction perpendicular to the up-down direction. The second slot segment 211cb is located on the step surface 211d. Outer peripheries of the first slot segment 211ca and the second slot segment 211cb are both wrapped with the inner ring jacket 232. the lower end of the first slot segment 211ca is in communication with the aerosol guide channel 13a. The upper end of the first slot segment 211ca is in communication with one end of the second slot segment 211cb. The other end of the second slot segment 211cb is in communication with the replenishment chamber 21a.
Referring to FIG. 9 to FIG. 10, the structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 in the foregoing embodiments, and includes a vaporization assembly 1 and a replacement assembly 2. The vaporization assembly 1 includes a vaporization holder 11, a vaporization core 12, and a vaporization base 13. A difference lies in that no assembly groove is provided in the vaporization assembly 1, and the replacement assembly 2 is detachably connected to the vaporization assembly 1 in a manner of being sleeved in the vaporization base 13. In addition, the replacement assembly 2 includes a sealing cover 23 covering the opening of the replenishment chamber 21a. The conduction structure 3 includes a piercing member 31 disposed on the partition plate 112. The conduction structure 3 further includes a first protective cap 31d disposed on the piercing member 31. The function of the first protective cap 31d is to prevent an e-liquid in the accommodating groove 11b of the vaporization assembly 1 from flowing out of the flow guide channel inside the piercing member 31. In addition, because the tip of the piercing member 31 is particularly sharp, to ensure the use safety of the vaporization assembly 1, when the vaporization assembly 1 is sold or transported alone, the first protective cap 31d may be used to protect the piercing port 31a at the upper end of the piercing member 31, to prevent a human hand from accidentally touching the piercing member 31 to cause damage. As shown in FIG. 10, when the replacement assembly 2 needs to be mounted on the vaporization assembly 1, the first protective cap 31d may be first removed to expose the piercing member 31. In a process of mounting the replacement assembly 2 into the assembly groove 11a from top to bottom, the piercing member 31 can abut against the sealing cover 23 and pierce the sealing cover 23, so that the vaporization substrate in the replenishment chamber 21a can flow into the accommodating groove 11b through the flow guide channel 31c, thereby implementing continuous liquid supply to the accommodating groove 11b.
Referring to FIG. 9 and FIG. 10 again, in this embodiment, a suction nozzle 13c in communication with the aerosol guide channel 13a may be provided at the top of the vaporization base 13, and a second protective cap 13d configured to seal the suction nozzle 13c is further provided on the vaporization base 13. When the replacement assembly 2 needs to be mounted on the assembly groove 11a of the vaporization assembly 1, the second protective cap 13d may be first removed to keep the suction nozzle 13c smooth. In addition, because the suction nozzle 13c is disposed on the vaporization assembly 1, and a suction nozzle may not be disposed on the replacement assembly 2. In this case, the replacement assembly 2 may be merely a sealing structure used as the replenishment chamber 21a. For example, the shape of the replacement assembly 2 may be an annular sleeve tube.
Referring to FIG. 11 to FIG. 14, the structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 in the foregoing embodiments. A difference lies in that the sealing cover 23 includes an annular cover plate 233 and a blocking member 234 disposed on the annular cover plate 233.
Two flow guide holes 233a corresponding to the piercing member 31 are opened in the annular cover plate 233. Referring to FIG. 14, the blocking member 234 includes a main body portion 234a and two blocking portions 234b. The main body portion 234a is generally annular. The two blocking portions 234b are movably connected to the main body portion 234a by two suspension arms 234c. The shape of the blocking portion 234b is similar to that of a plug, and the blocking portion 234b may completely seal the flow guide holes 233a.
When the replacement assembly 2 is not mounted on the vaporization assembly 1, the two blocking portions 234b are located in the two flow guide holes 233a, respectively, to prevent the vaporization substrate in the replenishment chamber 21a from flowing out of the flow guide holes 233a.
In a process of mounting the replacement assembly 2 into the assembly groove 11a from top to bottom, the piercing member 31 can abut against the blocking portion 234b, and further push the blocking portion 234b to move upward to separate from the flow guide holes 233a, so that the vaporization substrate in the replenishment chamber 21a can flow into the accommodating groove 11b through the flow guide holes 233a and the flow guide channel 31c, thereby implementing continuous liquid supply to the accommodating groove 11b. After the blocking portion 234b separates from the flow guide holes 233a, because the blocking portion 234b is always connected to the main body portion 234a by the suspension arms 234c, the blocking portion 234b does not randomly move in the replenishment chamber 21a to generate noise.
It may be understood that in another embodiment, the blocking member 234 may alternatively include only the blocking portion 234b. The blocking portion 234b can block the flow guide holes 233a, and can also separate from the flow guide holes 233a under the action of the piercing member 31. In this case, the main body portion 234a may be omitted.
Referring to FIG. 15 to FIG. 17, the structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 in the foregoing embodiments. A difference lies in that a first clamping boss 213 is formed on one of the outer peripheral wall of the jacket 21 and the annular sleeve 111, and a first clamping slot 11aa is formed on the other one of the outer peripheral wall of the jacket 21 and the annular sleeve 111. That is, when the first clamping boss 213 is disposed on the outer peripheral wall of the jacket 21, the first clamping slot 11aa is provided in the annular sleeve 111. When the first clamping slot 11aa is provided in the outer peripheral wall of the jacket 21, the first clamping boss 213 is disposed on the annular sleeve 111. The first clamping boss 213 is in snap fit with the first clamping slot 11aa.
As shown in FIG. 15, in an embodiment, the first clamping boss 213 is disposed on the outer peripheral wall of the outer ring shell 212. As shown in FIG. 22, the first clamping slot 11aa is disposed on the annular sleeve 111.
As shown in FIG. 17, each of the two end surfaces of the first clamping boss 213 that face and face away from a slide-in direction is a slope surface a, and an angle between the slope surface a and the outer peripheral wall of the jacket 21 is an obtuse angle. A direction in which the outer ring shell 212 enters the assembly groove 11a from top to bottom in FIG. 17 is defined as the slide-in direction, the slope surface a is a flat surface, and the angle α between the slope surface a and the outer peripheral wall of the outer ring shell 212 is an obtuse angle. With such an arrangement, the assembly and disassembly between the jacket 21 and the vaporization holder 11 both use quick-release fastening, especially when the jacket 21 of the replenishment chamber 21a storing the vaporization substrate needs to be replaced.
Referring to FIG. 18 to FIG. 22, the structure of an electronic vaporization device 100 according to another embodiment of this application is similar to that of the electronic vaporization device 100 in the foregoing embodiments. A difference lies in that a second clamping boss 214 is formed on one of the outer peripheral wall of the jacket 21 and the annular sleeve 111, and a second clamping slot 11ab is formed on the other one of the outer peripheral wall of the jacket 21 and the annular sleeve 111. That is, when the second clamping boss 214 is disposed on the outer peripheral wall of the jacket 21, the second clamping slot 11ab is provided in the annular sleeve 111. When the second clamping slot 11ab is provided in the outer peripheral wall of the jacket 21, the second clamping boss 214 is disposed on the annular sleeve 111. The second clamping boss 214 is in snap fit with the second clamping slot 11ab.
Referring to FIG. 18 and FIG. 19, in this embodiment, the second clamping boss 214 is disposed on the outer peripheral wall of the outer ring shell 212. As shown in FIG. 22, the second clamping slot 11ab is disposed on the annular sleeve 111, and the second clamping boss 214 is snapped in the second clamping slot 11ab. As shown in FIG. 20, the end surface of the second clamping boss 214 facing the slide-in direction is a slope surface a, and the end surface of the second clamping boss 214 facing away from the slide-in direction is a stop surface b. An angle between the slope surface a and the outer peripheral wall of the jacket 21 is an obtuse angle, and an angle between the stop surface b and the outer peripheral wall of the jacket 21 is a right angle or an acute angle. A direction in which the outer ring shell 212 enters the assembly groove 11a from top to bottom in FIG. 20 is used as the slide-in direction. The slope surface a is a flat surface, and an angle α between the slope surface a and the outer peripheral wall of the outer ring shell 212 is an obtuse angle. The stop surface b is a flat surface, and an angle β between the stop surface b and the outer peripheral wall of the outer ring shell 212 is a right angle. In this way, the assembly between the jacket 21 and the vaporization holder 11 uses quick-release fastening, and it is relatively easy for the jacket 21 to be assembled into the assembly groove 11a in the slide-in direction. The disassembly between the jacket 21 and the vaporization holder 11 uses permanent fastening, and it is relatively difficult for the jacket 21 to be disassembled from the assembly groove 11a in an opposite direction of the slide-in direction. In this way, it is difficult to disassemble the jacket 21 after assembly, especially if the jacket 21 is a replenishment chamber 21a and needs to supply the liquid to the accommodating groove 11b, thereby ensuring a more reliable connection between the jacket 21 and the assembly groove 11a.
Referring to FIG. 2, in an embodiment, the electronic vaporization device 100 includes a power supply module 200. The power supply module 200 is configured to supply power to the vaporization assembly 1 to provide energy required by the vaporization core 12 to heat the vaporization substrate. Specifically, the power supply module 200 is disposed at the end of the vaporization holder 11 close to the accommodating groove 11b.
In an embodiment, the power supply module 200 includes a battery 201, a control board assembly 202, and a power supply holder 203. The battery 201 and the control board assembly 202 are both disposed on the power supply holder 203. The power supply holder 203 is configured to fix and support the battery 201 and the control board assembly 202. The battery 201 is configured to provide electric energy to the control board assembly 202 and the heating element 121. The lower end of the annular sleeve 111 of the vaporization holder 11 is sleeved to the upper end of the power supply holder 203. The vaporization assembly 1 includes a sealing plug 15 configured to close the accommodating groove 11b, and the sealing plug 15 is hermetically sleeved at an opening at the end of the accommodating groove 11b away from the partition plate 112, to prevent that the vaporization substrate in the accommodating groove 11b from permeating into the power supply holder 203.
In an embodiment, referring to FIG. 2 and FIG. 3, the electronic vaporization device 100 includes a casing 300, and both the vaporization assembly 1 and the power supply module 200 are disposed inside the casing 300, to keep the overall appearance of the electronic vaporization device 100.
In an embodiment, referring to FIG. 2, a gap between the casing 300 and the battery 201, a gap between the power supply holder 203 and the sealing plug 15, and a gap between the battery 201 and the power supply holder 203 are all filled with a liquid absorbing member 204, for example, liquid absorbing cotton. The liquid absorbing cotton can further avoid permeation of the vaporization substrate in the accommodating groove 11b into the power supply module 200, thereby improving the operational reliability of the electronic vaporization device 100.
In an embodiment, a connection manner between the power supply holder 203 and the vaporization holder 11 is not limited. That is, the power supply holder 203 and the vaporization holder 11 may be integrally formed, or the power supply holder 203 and the vaporization holder 11 may be separately manufactured, and then assembled and connected in a detachable form.
In this application, an orientation relationship or a position relationship indicated by an "extension direction" is based on an orientation relationship or a position relationship shown in FIG. 25. It should be understood that these orientation terms are only used to facilitate description of this application and simplify description, but are not used to indicate or imply that the apparatuses or elements must have specific orientations or are constructed and operated by using specific orientations, and therefore, cannot be understood as a limit to this application.
Referring to FIG. 23 and FIG. 24, an electronic vaporization device according to an embodiment includes a housing assembly 10, a vaporization assembly 20, and a ventilation and pressure stabilization structure 30.
The housing assembly 10 includes an outer shell 12 and an air outlet tube 11 provided with an air outlet channel 10b. A liquid storage tank 10a (that is, the replenishment chamber 21a in FIG. 5) is formed between the outer shell 12 and the air outlet tube 11. Specifically, the liquid storage tank 10a is configured to contain a to-be-vaporized liquid, for example, a medical liquid or an e-liquid. In a puffing process of a user, the to-be-vaporized liquid in the liquid storage tank 10a can be guided to the vaporization assembly 20, and the vaporization assembly 20 can heat the to-be-vaporized liquid to form an aerosol for the user to puff.
The air outlet channel 10b is a channel enabling airflow in the housing assembly 10 to flow out. The housing assembly 10 is provided with an air inlet. In a puffing process, the air inlet is in communication with the air outlet channel 10b to form an airflow path.
Referring to FIG. 25, the vaporization assembly 20 is disposed in the housing assembly 10. The vaporization assembly 20 closes the liquid storage tank 10a, and the vaporization assembly 20 is provided with a vaporization channel 20a in communication with the air outlet channel 10b.
Specifically, the vaporization assembly 20 is configured to vaporize the to-be-vaporized liquid from the liquid storage tank 10a into an aerosol. The vaporization channel 20a is located on the airflow path. In a puffing process of a user, external airflow flows into the housing assembly 10 from the air inlet, flows through the vaporization channel 20a along the airflow path, and flows out from the air outlet channel 10b. The aerosol formed in the vaporization channel 20a can flow with the airflow for the user to puff.
The ventilation and pressure stabilization structure 30 (that is, the sealing jacket 22 in FIG. 3) is connected to at least one of the vaporization assembly 20 and the air outlet tube 11. The ventilation and pressure stabilization structure 30 can form a stable ventilation resistance that hinders the flow of air between the vaporization channel 20a and the liquid storage tank 10a, to prevent the liquid storage tank 10a from being directly in communication with the atmosphere.
Specifically, referring to FIG. 25, the ventilation and pressure stabilization structure 30 includes an extension portion 31 extending into the liquid storage tank 10a. The extension portion 31 is sleeved around the end of the air outlet tube 11 close to the vaporization assembly 20. The extension portion 31 cooperates with the air outlet tube 11 to form the ventilation resistance that hinders the flow of air between the vaporization channel 20a and the liquid storage tank 10a. When the vaporizer is in a ventilation state, a ventilation channel 10c that establishes communication between the liquid storage tank 10a and the vaporization channel 20a is formed between the extension portion 31 and the air outlet tube 11.
It should be noted that the flow of the to-be-vaporized liquid in the liquid storage tank 10a to the vaporization assembly 20 for vaporization is not implemented through the ventilation channel 10c. The ventilation channel 10c is only an air inlet channel configured to balance air pressure between the liquid storage tank 10a and the outside.
Specifically, referring to FIG. 25, in some embodiments, the extension portion 31 and the air outlet tube 11 are joined to each other, and the ventilation channel 10c is formed only when the vaporizer is in the ventilation state. Gas in the vaporization channel 20a can overcome the ventilation resistance to flow along the ventilation channel 10c into the liquid storage tank 10a.
In some embodiments, alternatively, the ventilation channel 10c may continuously exist between the extension portion 31 and the air outlet tube 11, but the ventilation channel 10c establishes communication between the vaporization channel 20a and the liquid storage tank 10a only when the vaporizer is in the ventilation state, and the ventilation channel 10c is blocked to form the ventilation resistance when the vaporizer is in another state (for example, in a puffing process). When the vaporizer is in a non-ventilation state, for example, in a puffing process, because the airflow in the vaporization channel 20a flows to the air outlet channel 10b, negative pressure is formed in the vaporization channel 20a, and the to-be-vaporized liquid in the liquid storage tank 10a flows to the vaporization assembly 20 for vaporization. The ventilation resistance exists between the vaporization channel 20a and the liquid storage tank 10a, and therefore no airflow flows.
After the puffing action ends, no airflow exists in the vaporization channel 20a to restore atmospheric pressure, and negative pressure exists in the liquid storage tank 10a due to the reduction of the to-be-vaporized liquid in a puffing process. When a pressure difference reaches an extent to enable the vaporizer to enter the ventilation state, air in the vaporization channel 20a can overcome the ventilation resistance to flow along the ventilation channel 10c into the liquid storage tank 10a, to balance air pressure between the liquid storage tank 10a and the outside.
It should be noted that no matter how the to-be-vaporized liquid in the liquid storage tank 10a changes, the extension portion 31 and the air outlet tube 11 can cooperate to form the ventilation resistance. That is, even if the to-be-vaporized liquid in the liquid storage tank 10a is completely consumed, the extension portion 31 and the air outlet tube 11 can still cooperate to form the ventilation resistance.
Therefore, the extension portion 31 is disposed, so that it can be ensured that the ventilation resistance continuously exists between the liquid storage tank 10a and the vaporization channel 20a, and air in the vaporization channel 20a needs to overcome the ventilation resistance before the air can flow to the liquid storage tank 10a. Therefore, the liquid storage tank 10a can be prevented from being directly in communication with the atmosphere, to avoid an excessive amount of liquid provided by a single oral cavity in a puffing process, thereby preventing occurrence of problems such as attenuation of the aerosol amount and severe liquid leakage.
In an embodiment, referring to FIG. 25, the extension portion 31 and the air outlet tube 11 are disposed spaced apart, and a capillary space 31d is formed between the extension portion 31 and the air outlet tube 11. The capillary space 31d is at least part of the ventilation channel 10c. The capillary space 31d is in communication with the liquid storage tank 10a, and the to-be-vaporized liquid in the liquid storage tank 10a can fill the capillary space 31d under capillary action to form the ventilation resistance between the vaporization channel 20a and the liquid storage tank 10a.
Specifically, a spacing between the extension portion 31 and the air outlet tube 11 is less than or equal to 1 mm, so that the to-be-vaporized liquid in the liquid storage tank 10a can fill the capillary space 31d under the capillary action.
Therefore, even if the level of the to-be-vaporized liquid in the liquid storage tank 10a decreases below the top of the capillary space 31d or even the to-be-vaporized liquid in the liquid storage tank 10a is used up, the to-be-vaporized liquid in the capillary space 31d is unlikely to flow out. In addition, even if part of the to-be-vaporized liquid in the capillary space 31d leaks out in a special case, the to-be-vaporized liquid in the liquid storage tank 10a can be quickly replenished into the capillary space 31d. Therefore, it can be ensured that the extension portion 31 can cooperate with the air outlet tube 11 to always form a ventilation resistance, so that a stable ventilation resistance can be formed between the liquid storage tank 10a and the vaporization channel 20a, and communication between the liquid storage tank 10a and the vaporization channel 20a is unlikely to be established.
It may be understood that the capillary space 31d may be part of the ventilation channel 10c or may be the entire region of the ventilation channel 10c. When the vaporizer is in the ventilation state, a ventilation path passing through the capillary space 31d is formed between the vaporization channel 20a and the liquid storage tank 10a.
It should be noted that only a partial region of the extension portion 31 may cooperate with the air outlet tube 11 to maintain a stable ventilation resistance all the time, or the entire region of the extension portion 31 may cooperate with the air outlet tube 11 to form a ventilation resistance. This depends on the magnitude of the capillary force between the capillary space 31d and the to-be-vaporized liquid, and therefore is related to the material of the extension portion 31, a specific size of the capillary space 31d, and the like.
In an embodiment, referring to FIG. 25, a first communication port 31a and a second communication port 31b are provided at two opposite ends of the extension portion 31 in an extension direction, respectively. The first communication port 31a is in communication with the vaporization channel 20a and the capillary space 31d, and the second communication port 31b is in communication with the capillary space 31d and the liquid storage tank 10a. A liquid supply slot 31c (referring to FIG. 28) in communication with the liquid storage tank 10a and the capillary space 31d is opened in the side wall of the extension portion 31.
Specifically, when the vaporizer is in the ventilation state, a ventilation path that passes through the first communication port 31a, the capillary space 31d, and the second communication port 31b is formed between the vaporization channel 20a and the liquid storage tank 10a. The liquid supply slot 31c is formed for the liquid storage tank 10a to be in communication with the capillary space 31d, and liquid can be continuously supplied to the capillary space 31d.
It should be noted that the specific shape, number, and arrangement position of the liquid supply slots 31c are not limited, and the liquid supply slot 31c may be, for example, a circular hole or a square hole.
For example, referring to FIG. 28, the liquid supply slot 31c is a strip-shaped slot extending along the extension direction of the extension portion 31, and an end of the liquid supply slot 31c in the extension direction of the liquid supply slot 31c is in communication with the second communication port 31b.
Specifically, one end of the liquid supply slot 31c extends to the second communication port 31b, and the other end of the liquid supply slot 31c may extend to the first communication port 31a or may not be in communication with the first communication port 31a.
In an embodiment, referring to FIG. 28, two liquid supply slots 31c are formed in the side wall of the extension portion 31, and the two liquid supply slots 31c are provided offset with respect to the center of the air outlet tube 11.
Specifically, that the two liquid supply slots 31c are provided staggered with respect to the center of the air outlet tube 11 means that a connecting line between the two liquid supply slots 31c does not pass through the center of the air outlet tube 11, that is, the two liquid supply slots 31c are displaced with respect to each other. In this way, it can be avoided that when the vaporizer is placed obliquely, the to-be-vaporized liquid in the capillary space 31d tends to leak out of the liquid supply ports 31c, to avoid blocking failure of the to-be-vaporized liquid in the capillary space 31d.
In an embodiment, referring to FIG. 26 and FIG. 27, a ventilation groove 11a is provided in the outer surface of the end of the air outlet tube 11 close to the vaporization assembly 20, and the ventilation groove 11a forms part of the ventilation channel 10c. One end of the ventilation groove 11a is in communication with the vaporization channel 20a, and the other end of the ventilation groove 11a extends to the extension portion 31. When the vaporizer is in a ventilation state, the capillary space 31d is in communication with the liquid storage tank 10a and the ventilation groove 11a.
Specifically, the ventilation channel 10c includes the ventilation groove 11a and the capillary space 31d. The extension portion 31 blocks the end of the ventilation groove 11a facing away from the vaporization assembly 20 for a ventilation resistance is formed between the vaporization channel 20a and the liquid storage tank 10a.
It should be noted that the side surface of the ventilation groove 11a is provided with an opening facing the extension portion 31, and the extension portion 31 covers the opening. When the vaporizer is in a non-ventilation state, the extension portion 31 blocks one end of the ventilation groove 11a, and the other end of the ventilation groove 11a is in communication with the vaporization channel 20a, so that the ventilation groove 11a can be filled with air. When the vaporizer is in a ventilation state, air can push the extension portion 31 through the ventilation groove 11a for at least a partial region of the extension portion 31 to separate from the air outlet tube 11.
That is, more air can be accumulated by arranging the ventilation groove 11a, so that a force-bearing area of the extension portion 31 in the ventilation state is larger, the extension portion 31 can be opened more easily, and it is convenient for air in the vaporization channel 20a to push open the extension portion 31.
In an embodiment, referring to FIG. 27, the ventilation groove 11a includes a first sub-groove 11aa and a second sub-groove 11ab located at the end of the first sub-groove 11aa facing away from the vaporization assembly 20. Two opposite ends of the first sub-groove 11aa in the extension direction are in communication with the second sub-groove 11ab and the vaporization channel 20a, respectively. The cross-sectional area of the first sub-groove 11aa is less than the cross-sectional area of the second sub-groove 11ab. In this way, the size of a communication point between the ventilation groove 11a and the vaporization channel 20a can be reduced, so that a case in which the to-be-vaporized liquid in the liquid storage tank 10a flows out to the vaporization channel 20a through the ventilation groove 11a to cause liquid leakage can be prevented.
Referring to FIG. 29 and FIG. 30, the structure of a vaporizer according to another embodiment is similar to that of the vaporizer in the foregoing embodiments. The vaporizer includes a housing assembly 10, a vaporization assembly 20, and a ventilation and pressure stabilization structure 30. A difference lies in that, in this embodiment, when the vaporizer is in a non-ventilation state, at least a partial region of the extension portion 31 is joined to the air outlet tube 11 to separate the vaporization channel 20a and the liquid storage tank 10a. When the vaporizer is in a ventilation state, at least a partial region of the extension portion 31 separates from the air outlet tube 11 to form a ventilation channel 10c that establishes communication between the liquid storage tank 10a with the vaporization channel 20a.
Specifically, according to an actual situation, the entire region of the extension portion 31 may be joined to the air outlet tube 11, or only a partial region of the extension portion 31 is joined to the air outlet tube 11. In addition, that the extension portion 31 is in contact with the air outlet tube 11 does not mean that the extension portion 31 and the air outlet tube 11 are inseparable. In practice, the extension portion 31 is in contact with the air outlet tube 11 in a separable manner. That is, when the vaporization channel 20a is at atmospheric pressure and the liquid storage tank 10a is at negative pressure, the vaporizer is in a ventilation state, and air in the vaporization channel 20a can push the extension portion 31 to separate from the air outlet tube 11, to enter the liquid storage tank 10a through the ventilation channel 10c.
It should be noted that the magnitude of the ventilation resistance formed by the extension portion 31 and the air outlet tube 11 being joined to each other and the size of the ventilation channel 10c may be determined according to an actual situation, and is related to the material property of the extension portion 31.
For example, when the extension portion 31 is made of a silicone material, a spacing of the ventilation channel 10c between the extension portion 31 and the air outlet tube 11 is greater than 0.2 mm and less than 0.4 mm, for example, 0.3 mm. Certainly, the extension portion 31 may alternatively be made of plastic, a steel plate, or another material.
Only a partial region of the extension portion 31 may separate from the air outlet tube 11 to form the ventilation channel 10c. Certainly, according to an actual situation, the entire region of the extension portion 31 may separate from the air outlet tube 11 to form the ventilation channel 10c.
When the liquid storage tank 10a stores the to-be-vaporized liquid, the to-be-vaporized liquid can press the extension portion 31. Therefore, the extension portion 31 and the air outlet tube 11 can be more tightly joined to each other when the vaporizer is in a non-ventilation state (for example, in a puffing process), thereby preventing liquid leakage.
In another embodiment, the extension portion 31 and the air outlet tube 11 may alternatively be sealed by an oil film to improve a separation effect of the extension portion 31 for the vaporization channel 20a and the liquid storage tank 10a, thereby achieving a better pressure stabilization effect.
In an embodiment, referring to FIG. 30 and FIG. 31, the extension portion 31 includes two valve plates 311 detachably joined to two opposite sides of the air outlet tube 11 in a radial direction, and the two valve plates 311 are disposed oppositely and spaced apart.
Specifically, the two valve plates 311 are two flexible arc-shaped plates disposed on two opposite sides of the air outlet tube 11. Therefore, under the pushing action of airflow in the ventilation groove 11a, the two valve plates 311 may move away from each other to separate from the air outlet tube 11.
In addition, the number of the ventilation grooves 11a is not limited. A plurality of ventilation grooves 11a may be disposed, so that different valve plates 311 of different ventilation grooves 11a correspondingly cooperate with each other. Certainly, only one ventilation groove 11a may alternatively be disposed to correspond to two valve plates 311. As shown in FIG. 25 and FIG. 30, the vaporization assembly 20 includes a central tube (that is, the vaporization base 13 in FIG. 3), a vaporization core, and a liquid absorbing cotton. The vaporization core and the liquid absorbing cotton are disposed in the central tube. The liquid absorbing cotton is located between the central tube and the air outlet tube 11. The vaporization core is provided with a vaporization chamber in communication with the air inlet. The air outlet tube 11 is provided with a flow passage channel with two ends that are correspondingly in communication with the air outlet channel 10b and the vaporization chamber. The flow passage channel and the vaporization chamber jointly form at least part of the vaporization channel 20a. The ventilation channel 10c is in communication with the flow passage channel.
An embodiment of this application further provides an electronic vaporization device, including a power supply assembly and the vaporizer in any foregoing embodiment. The power supply assembly is electrically connected to the vaporization assembly 20.
Referring to FIG. 32 to FIG. 34, an embodiment of this application provides an electronic vaporization device. The electronic vaporization device may be configured to contain a to-be-vaporized liquid, for example, a medical liquid or an e-liquid, and vaporize the to-be-vaporized liquid to generate an aerosol for a user to inhale. The electronic vaporization device includes a housing assembly 10 and a vaporization assembly 20. The housing assembly 10 is provided with an air inlet, a flow guide channel 12 (a, referring to FIG. 35) in communication with the air inlet, and an air outlet channel 10d provided with an air outlet 10e. The flow guide channel 12a and the air outlet channel 10d are provided spaced apart.
The vaporization assembly 20 is disposed in the housing assembly 10, and is located between the flow guide channel 12a and the air outlet channel 10d. The vaporization assembly 20 is provided with a vaporization channel 20a. The end surfaces of two opposite ends of the vaporization assembly 20 are in contact with the housing assembly 10 for the vaporization channel 20a to be in communication with the air outlet channel 10d and the flow guide channel 12a. An airflow circulation path including the flow guide channel 12a, the vaporization channel 20a, and the air outlet channel 10d is formed between the air inlet and the air outlet. A liquid guide path including the vaporization channel 20a is formed between the air outlet channel 10d and the flow guide channel 12a.
The electronic vaporization device includes the housing assembly 10 and the vaporization assembly 20. The airflow circulation path passing at least through the flow guide channel 12a, the vaporization channel 20a, and the air outlet channel 10d is formed between the air inlet and the air outlet 10e of the housing assembly 10, and the liquid guide path passing through the vaporization channel 20a is formed between the air outlet channel 10d and the flow guide channel 12a. The end surfaces of two opposite ends of the vaporization assembly 20 are in contact with the housing assembly 10 for the vaporization channel 20a to be in communication with the air outlet channel 10d and the flow guide channel 12a. Therefore, no step surfaces exist between the two ends of the vaporization assembly 20 and the housing assembly 10, so that a leaking liquid can flow along the liquid guide path, and therefore, the leaking liquid can be prevented from converging at the two ends of the vaporization assembly 20, and when a user takes a puff, the electronic vaporization device can be prevented from generating a gurgling sound, thereby improving user experience.
The air inlet is configured to allow an external airflow to flow into the housing assembly 10. In a puffing process of a user, external airflow flows into the housing assembly 10 from the air inlet, flows through the vaporization channel 20a and the air outlet channel 10d along the airflow circulation path, and flows out from the air outlet 10e. The aerosol formed in the vaporization channel 20a can flow with the airflow for the user to puff.
The size of the vaporization channel 20a has a large impact on the puffing feel of a user. In an embodiment, the inner diameter of the vaporization channel 20a is greater than 2.2 mm and not greater than 2.5 mm. Preferably, the inner diameter of the vaporization channel 20a is 2.3 mm, 2.4 mm, or 2.5 mm. The inner diameter of the vaporization channel 20a should not exceed 2.5 mm, to avoid degradation of user experience. The inner diameter of the vaporization channel 20a should also not be excessively small, to avoid hindering of the flow of the leaking liquid along the liquid guide path.
It should be noted that one end of the vaporization assembly 20 is in contact with a region of the housing assembly 10 provided with the air outlet channel 10d, so that the vaporization channel 20a is in communication with the air outlet channel 10d. The other end of the vaporization assembly 20 is in contact with a region of the housing assembly 10 provided with the flow guide channel 12a for the vaporization channel 20a to be in communication with the flow guide channel 12a. Therefore, a continuous channel may be formed for the leaking liquid to flow along the liquid guide path.
A specific structure of the vaporization assembly 20 is not limited, and may be set according to an actual situation.
Referring to FIG. 35, in this embodiment, the vaporization assembly 20 includes a first flow guide member 21 provided with a first channel 21a and a vaporization core 22 provided with a second channel 22a. The first channel 21a and the second channel 22a jointly form part of the vaporization channel 20a. The end surfaces of two opposite ends of the first flow guide member 21 are in contact with the vaporization core 22 and the housing assembly 10, respectively, for the second channel 22a to be in communication with the air outlet channel 10d through the first channel 21a.
Specifically, the second channel 22a, the first channel 21a, and the air outlet channel 10d are continuous. The vaporization core 22 is a structure configured to heat the to-be-vaporized liquid in the vaporization assembly 20. The first flow guide member 21 is disposed between the vaporization core 22 and the air outlet channel 10d, so that the vaporization core 22 can be isolated from the air outlet channel 10d, thereby preventing the vaporization core 22 from being excessively hot to damage the air outlet channel 10d. In addition, specific sizes of the second channel 22a, the first channel 21a, and the air outlet channel 10d may be set according to an actual situation.
It should be noted that the inner walls of the air outlet channel 10d, the vaporization channel 20a, and the flow guide channel 12a are continuously disposed, and no step surface is formed at connection points between the air outlet channel 10d, the vaporization channel 20a, and the flow guide channel 12a. Therefore, the flow guiding effect can be further improved, to prevent the leaking liquid from converging. In another embodiment, a narrow gap may exist between the end surfaces of the vaporization assembly 20 and the housing assembly 10 or a small step surface may be formed between the inner walls of the channels. However, the narrow gap and the small step surface do not affect the flow of the leaking liquid along a flow guide path. For example, because an error exists in actual production, a small gap or step surface exists at a connection point between the vaporization assembly 20 and the housing assembly 10. However, in an actual use process, the gap or the step surface cannot cause the leaking liquid to converge here, and does not affect the flow of the leaking liquid along the flow guide path.
In an embodiment, the inner wall surface of the first channel 21a is coplanar with the inner wall surface of the second channel 22a and the inner wall surface of the air outlet channel 10d. That is, the sizes of connection points of the first channel 21a, the second channel 22a, and the air outlet channel 10d are the same, and the first channel 21a, the second channel 22a, and the air outlet channel 10d may smoothly transition.
The first channel 21a and the second channel 22a jointly form part of the vaporization channel 20a. That is, the vaporization channel 20a may include only the first channel 21a and the second channel 22a, and certainly may further include other channels.
Referring to FIG. 35, the vaporization assembly 20 further includes a sealing plug 24 that is disposed on a side of the vaporization core 22 facing away from the first flow guide member 21 and that is configured to seal a flow guide chamber 10f. The sealing plug 24 is provided with a third channel 24a. Two opposite ends of the sealing plug 24 are in contact with the vaporization core 22 and the holder assembly 12, respectively, for the flow guide channel 12a to be in communication with the second channel 22a through the third channel 24a. The first channel 21a, the second channel 22a, and the third channel 24a jointly form the vaporization channel 20a. No steps exist between the two opposite ends of the sealing plug 24 and the vaporization core 22 and the holder assembly 12, so that the inner walls of the flow guide channel 12a, the third channel 24a, and the second channel 22a are continuously disposed. The sealing plug 24 may be a silicone cover.
Specific sizes of the flow guide channel 12a and the third channel 24a may be set according to an actual situation. For example, the inner wall surface of the flow guide channel 12a is coplanar with the inner wall surface of the third channel 24a. That is, the wall surfaces of the flow guide channel 12a and the third channel 24a at at least the connection points have the same size, and may have smooth transition.
In an embodiment, referring to FIG. 34 and FIG. 35, the housing assembly 10 includes an outer shell 11 and a holder assembly 12 provided with the flow guide channel 12a, and the holder assembly 12 is disposed in the outer shell 11. The housing assembly 10 further includes a liquid absorbing tank 10a located on a side of the holder assembly 12, and the end of the flow guide channel 12a facing away from the third channel 24a is in communication with the liquid absorbing tank 10a for the liquid guide path to extend into the liquid absorbing tank 10a.
Specifically, the liquid absorbing tank 10a is configured to contain and absorb a leaking liquid from the ventilation channel 10c and the vaporization channel 20a. The vaporization channel 20a is in communication with the liquid absorbing tank 10a through the flow guide channel 12a. Therefore, the leaking liquid in the vaporization channel 20a can flow along the liquid guide path, and flow to the liquid absorbing tank 10a through the flow guide channel 12a.
A specific arrangement position of the liquid absorbing tank 10a is not limited. In this embodiment, the liquid absorbing tank 10a is a battery compartment, which is configured to arrange a battery of the electronic vaporization device and liquid absorbing cotton, where the liquid absorbing cotton is configured to absorb and store a leaking liquid flowing along the liquid guide path.
In an embodiment, referring to FIG. 38, the holder assembly 12 includes a holder 121 and a second flow guide member 122. The holder 121 is provided with an air passage chamber 121a (referring to FIG. 35), and the second flow guide member 122 is disposed in the air passage chamber 121a. The flow guide channel 12a is disposed in the second flow guide member 122, and the air passage chamber 121a and the flow guide channel 12a form part of the airflow circulation path.
Specifically, the external airflow flowing in from the air inlet sequentially flows through the air passage chamber 121a, the flow guide channel 12a, the vaporization channel 20a, and the air outlet channel 10d along the airflow circulation path, and flows out from the air outlet 10e of the air outlet channel 10d.
The air passage chamber 121a is disposed, so that airflow from the air outlet 10e can enter the flow guide channel 12a. The liquid absorbing cotton may not be disposed in the air passage chamber 121a, to prevent the liquid absorbing cotton from hindering the flow of the airflow, so that it can be ensured that the holder assembly 12 has a sufficient space for air exchange.
In some embodiments, in a case of ensuring the flow effect of the airflow, the liquid absorbing cotton may alternatively be disposed in the air passage chamber 121a, to absorb a leaking liquid flowing along the flow guide path.
Referring to FIG. 38, in this embodiment, the second flow guide member 122 includes two liquid guide columns 1221 disposed spaced apart in the air passage chamber 121a, and a flow guide channel 12a is formed at an interval between the two liquid guide columns 1221. The shape of the liquid guide column 1221 greatly affects the flow guiding effect of the flow guide channel 12a.
In this embodiment, surfaces of sides of the two flow guide columns 1221 close to each other are continuously disposed with the inner wall of the vaporization channel 20a. The foregoing continuous arrangement refers to continuity along the extension direction of the liquid guide path.
In an embodiment, referring to FIG. 34, the housing assembly 10 includes a liquid storage tank 10b (that is, the replenishment chamber 21a in FIG. 5) and a flow guide chamber 10f (that is, the accommodating groove 11b in FIG. 5) in communication with the liquid storage tank 10b. The sealing plug 24 is configured to seal the flow guide chamber 10f. The electronic vaporization device further includes first liquid guide cotton 30 disposed in the flow guide chamber 10f. The housing assembly 10 further includes a mounting cavity 30a configured to mount the vaporization core 22.
Specifically, the liquid storage tank 10b is a structure configured to store a to-be-vaporized liquid, for example, a medical liquid or an e-liquid, of the electronic vaporization device. In a puffing process of a user, the to-be-vaporized liquid in the liquid storage tank 10b can be guided to the vaporization assembly 20 for the vaporization assembly 20 to heat the to-be-vaporized liquid for vaporization to form an aerosol.
In the puffing process of the user, the vaporization core 22 may vaporize the to-be-vaporized liquid, and the first liquid guide cotton 30 can continuously guide the flow of the to-be-vaporized liquid in the liquid storage tank 10b to the vaporization core 22.
In an embodiment, referring to FIG. 34 to FIG. 37, the housing assembly 10 further includes the ventilation channel 10c, and the liquid storage tank 10b is in communication with the first channel 21a through the ventilation channel 10c. The ventilation channel 10c is provided with a ventilation inlet 10ca in communication with the first channel 21a and a ventilation outlet 10cb in communication with the liquid storage tank 10b. The distance between the ventilation outlet 10cb and the central cross-section of the liquid storage tank 10b is a first spacing, the distance between a communication point between the liquid storage tank 10b and the flow guide chamber 10f and the central cross-section is a second spacing, and the first spacing is not less than the second spacing. It should be noted that the central cross-section of the liquid storage tank 10b is a plane corresponding to a cross-section passing through the central point of the liquid storage tank 10b. With the central cross-section as reference, the distance between the ventilation outlet 10cb and the central cross-section should be greater than or equal to the distance between the communication point between the liquid storage tank 10b and the flow guide chamber 10f and the central cross-section.
Specifically, the flow of the to-be-vaporized liquid in the liquid storage tank 10b to the vaporization assembly 20 for vaporization is not implemented through the ventilation channel 10c. The ventilation channel 10c is only a channel configured to balance air pressure between the liquid storage tank 10b and the outside. In an embodiment, one end of the ventilation channel 10c is in communication with the liquid storage tank 10b, and the other end of the ventilation channel 10c is in communication with the atmosphere. For example, the ventilation channel 10c is in communication with the vaporization channel 20a or the air outlet channel 10d. During puffing of a user, part of the to-be-vaporized liquid in the liquid storage tank 10b may leak out through the ventilation channel 10c. In addition, the to-be-vaporized liquid that flows to the vaporization assembly 20 for heating and vaporization also leaks out to the vaporization channel 20a. Therefore, the liquid guide path is disposed for leaking liquids at two places to be guided to the liquid absorbing tank 10a, thereby preventing liquid leakage.
On the other hand, the first flow guide member 21 can have a flow guide function, and can guide the to-be-vaporized liquid that leaks out of the ventilation channel 10c into the first channel 21a to flow along the liquid guide path.
When the electronic vaporization device is in a use state or a vertical placement state, a ground clearance of the ventilation outlet 10cb is greater than a ground clearance of the communication point between the liquid storage tank 10b and the flow guide chamber 10f. It should be noted that when a liquid level of the to-be-vaporized liquid in the liquid storage tank 10b is consumed below the ventilation outlet 10cb, the ventilation outlet 10cb is directly in communication with a cavity in the liquid storage tank 10b. Consequently, the liquid storage tank 10b is directly in communication with the outside. The to-be-vaporized liquid in the liquid storage tank 10b continuously flows to the vaporization assembly 20 under the effect of gravity, causing a severe liquid leakage problem. A height difference is formed between the communication point between the liquid storage tank 10b and the flow guide chamber 10f and the ventilation outlet 10cb, to ensure that before the to-be-vaporized liquid in the liquid storage tank 10b is used up, the ventilation outlet 10cb remains located in the to-be-vaporized liquid, and negative pressure exists in the cavity in the liquid storage tank 10b, thereby avoiding severe liquid leakage in the vaporization assembly 20.
Referring to FIG. 40, the first flow guide member 21 includes third liquid guide cotton 211 provided with the first channel 21a. The third liquid guide cotton 211 is approximately C-shaped. A flow passage port 21b is formed in a partial region of the third liquid guide cotton 211. The flow passage port 21b is in communication with the first channel 21a and the ventilation channel 10c. Therefore, in a process in which the electronic vaporization device performs air exchange through the ventilation channel 10c, air in the first channel 21a may enter the ventilation channel 10c through the flow passage port 21b, and flow into the liquid storage tank 10b along the ventilation channel 10c.
Referring to FIG. 39, the vaporization assembly 20 includes a tube body 23, and a vaporization core 22 is disposed inside the tube body 23. A partial region of the tube body 23 is open to form a flow passage slot 23a for the to-be-vaporized liquid of the first liquid guide cotton 30 to flow to the vaporization core 22 through the flow passage slot 23a. The tube body 23 can achieve the function of limiting a liquid supply amount of the to-be-vaporized liquid flowing to the vaporization core 22. Specifically, the cross-sectional area of the flow passage slot 23a satisfies that the liquid supply amount of the to-be-vaporized liquid flowing to the vaporization core 22 is not greater than a vaporization amount of the vaporization core 22. Through proper setting of the cross-sectional area of the flow passage slot 23a, a liquid supply amount, per port per unit time, of the to-be-vaporized liquid that flows to the vaporization assembly 20 through the first liquid guide cotton 30 in the liquid storage tank 10b can be controlled, so that a liquid leakage amount in the vaporization channel 20a can be reduced.
It may be understood that when the liquid supply amount of the to-be-vaporized liquid flowing to the vaporization core 22 is not greater than the vaporization amount of the vaporization core 22, the liquid leakage amount in the vaporization channel 20a may be greatly reduced, so that convergence of the liquid leakage can be reduced, and generation of a gurgling sound can be prevented, thereby improving user experience.
Certainly, the liquid supply amount of the to-be-vaporized liquid flowing to the vaporization core 22 cannot be excessively low, which should satisfy a puffing requirement of a user. For example, the liquid supply amount of the to-be-vaporized liquid flowing to the vaporization core 22 may be equal to the vaporization amount of the vaporization core 22.
In an embodiment, the vaporization assembly 20 is located on the bottom side of the air outlet channel 10d, the holder assembly 12 is located on the bottom side of the vaporization assembly 20, and the liquid absorbing tank 10a is located on the bottom side of the flow guide channel 12a. The liquid guide path extends from top to bottom, and the airflow circulation path extends from bottom to top.
Referring to FIG. 35, the vaporization core 22 includes a heating member 221 and second liquid guide cotton 222 provided with the second channel 22a, and the heating member 221 is disposed in the second channel 22a. Specifically, the type of the heating member 221 is not limited, and the heating member 221 may be a heating sheet disposed on the inner wall of the second channel 22a.
Referring to FIG. 41, FIG. 42, FIG. 44, and FIG. 45, an embodiment of this application provides a power supply assembly used in an electronic vaporization device. The power supply assembly includes a housing assembly 10 and a microphone 40. The housing assembly 10 is provided with an air inlet 10a and an air outlet 10b, and an airflow path is formed between the air inlet 10a and the air outlet 10b. The airflow path is a channel for airflow to flow between the air inlet 10a and the air outlet 10b. External airflow enters from the air inlet 10a, flows along the airflow path, and finally flows out from the air outlet 10b.
As shown in FIG. 45, the microphone 40 is disposed in the housing assembly 10. The microphone 40 is provided with an atmospheric pressure sensing surface 40b and a negative pressure sensing surface 40a. The atmospheric pressure sensing surface 40b is configured to sense atmospheric pressure, and the negative pressure sensing surface 40a is configured to sense negative pressure in the airflow path. A manner of sensing the atmospheric pressure by the atmospheric pressure sensing surface 40b is not limited, provided that the atmospheric pressure can be maintained on the side of the atmospheric pressure sensing surface 40b. For example, at least a partial region of the atmospheric pressure sensing surface 40b is in communication with the airflow path. That is, the atmospheric pressure sensing surface 40b is in communication with the outer side of the housing assembly 10 through the communication with the airflow path. Certainly, apart from the communication with the airflow path, the atmospheric pressure sensing surface 40b may alternatively be in communication with the outer side of the housing assembly 10 through another opening. For example, a through hole in communication with the atmospheric pressure sensing surface 40b is further opened in the housing assembly 10. The atmospheric pressure sensing surface 40b is in communication with the outer side of the housing assembly 10 through the through hole.
In a puffing process, negative pressure is formed on the side of the negative pressure sensing surface 40a of the microphone 40, and the side of the atmospheric pressure sensing surface 40b of the microphone 40 is in communication with the outer side of the housing assembly 10. Therefore, the atmospheric pressure can be maintained. The microphone 40 is started by sensing a pressure difference between the two sides. It should be noted that, as shown in FIG. 44, an angle γ between a normal direction α of the negative pressure sensing surface 40a and an extension direction β of the air outlet 10b is greater than 90° and less than or equal to 180°. The normal direction α of the negative pressure sensing surface 40a is a direction perpendicular to the negative pressure sensing surface 40a. In an embodiment, the angle γ is equal to 180°, that is, the negative pressure sensing surface 40a is disposed opposite to the air outlet 10b. In a process of vertically placing the electronic vaporization device, external airflow moves toward a side of the air outlet 10b. Because the negative pressure sensing surface 40a is located on the side of the microphone 40 facing away from the air outlet 10b, and the atmospheric pressure sensing surface 40b is located on the side of the microphone 40 close to the air outlet 10b, that is, located on the leeward side of the microphone. Therefore, external airflow does not impact the atmospheric pressure sensing surface 40b in a reverse direction, so that the microphone 40 is started only due to a pressure difference formed between the negative pressure sensing surface 40a and the atmospheric pressure sensing surface 40b in a puffing process. Therefore, it can be avoided that when the atmospheric pressure sensing surface 40b of the microphone 40 faces away from a side of a wind outlet 10, the microphone 40 tends to be started due to a direct impact by external airflow, and therefore, incorrect starting of the microphone 40 can be avoided.
Referring to FIG. 42, FIG. 43, and FIG. 45, the power supply assembly further includes a holder assembly 20 disposed in the housing assembly 10. The holder assembly 20 is provided with a microphone mounting cavity 20c, and the microphone 40 is disposed in the microphone mounting cavity 20c. A region of the microphone mounting cavity 20c located on the side of the negative pressure sensing surface 40a is in communication with the airflow path. Referring to FIG. 44, the housing assembly 10 further includes a bottom cover 11. The air inlet 10a is opened in the bottom cover 11. The bottom cover 11 closes the microphone mounting cavity 20c, and is disposed spaced apart from the negative pressure sensing surface 40a.
The bottom cover 11 is located on the side of the microphone mounting cavity 20c facing away from the air outlet 10b, so that apart from being in communication with the airflow path, the microphone mounting cavity 20c can maintain optimal sealing performance. Specifically, the microphone mounting cavity 20c is merely in communication with the airflow path, so that when a user performs puffing through the air outlet 10b, negative pressure can be formed in the region of the microphone mounting cavity 20c located on the side of the negative pressure sensing surface 40a under the action of puffing at the air outlet 10b.
In this embodiment, the microphone 40 is not disposed on the bottom cover 11, but is disposed spaced apart from the bottom cover 11. Therefore, the space between the microphone 40 and the bottom cover 11 can be enlarged, and the liquid in the airflow path can be prevented from damaging the microphone 40 after entering the microphone mounting cavity 20c, to avoid a failure of the microphone 40.
In addition, the bottom cover 11 may be further provided with a liquid absorbing structure, to absorb or lock the liquid entering the microphone mounting cavity 20c.
Referring to FIG. 52 and FIG. 53, a liquid storage groove 111 having a capillary effect is formed in a partial region of the bottom cover 11 located in the microphone mounting cavity 20c. After entering the liquid storage groove 111, the liquid can relatively stably accumulate in the liquid storage groove 111 under the action of a capillary force, and does not easily flow out of the liquid storage groove 111 due to movement of the electronic vaporization device. Therefore, the liquid can be adequately prevented from damaging the microphone 40, thereby avoiding a failure of the microphone 40.
A specific formation manner of the liquid storage groove 111 is not limited. The liquid storage groove 111 may be formed by the partial region of the bottom cover 11 located in the microphone mounting cavity 20c protruding, or may be formed by the partial region of the bottom cover 11 located in the microphone mounting cavity 20c protruding being recessed.
For example, referring to FIG. 53, the liquid storage groove 111 includes a first liquid absorbing member 112, a second liquid absorbing member 113, and a third liquid absorbing member 114. The first liquid absorbing member 112 includes a first liquid absorbing groove 112a provided with a first opening 112b. The second liquid absorbing member 113 is disposed around the outer peripheral side of the first liquid absorbing member 112, and is spaced from the first liquid absorbing member 112 to form a second liquid absorbing groove 113a provided with a second opening 113b. The third liquid absorbing member 114 is disposed around the outer peripheral side of the second liquid absorbing member 113, and is spaced from the second liquid absorbing member 113 to form a third liquid absorbing groove 114a provided with a third opening 114a. The first liquid absorbing groove 112a, the second liquid absorbing groove 113a, and the third liquid absorbing groove 114a are in communication with each other.
The sizes of the first liquid absorbing groove 112a, the second liquid absorbing groove 113a, and the third liquid absorbing groove 114a need to be such that a capillary phenomenon can be formed, that is, a liquid entering the microphone mounting cavity 20c can fill the third liquid absorbing groove 114a, the second liquid absorbing groove 113a, and the first liquid absorbing groove 112a sequentially under the action of a capillary force. For example, the cross-sectional sizes of the first liquid absorbing groove 112a, the second liquid absorbing groove 113a, and the third liquid absorbing groove 114a are not greater than 1 mm×1 mm.
The shapes of the first liquid absorbing member 112, the second liquid absorbing member 113, and the third liquid absorbing member 114 are not limited, and are, for example, an arc shape, or a square shape with an opening.
In an embodiment, referring to FIG. 45 and FIG. 49 to FIG. 51, the holder assembly 20 includes a microphone mounting base 23. The microphone mounting base 23 includes a base body 233 disposed on the bottom cover 11 and a circuit board 234 located on the side of the base body 233 facing away from the bottom cover 11. The base body 233 and the circuit board 234 jointly enclose to form a microphone mounting cavity 20c, the circuit board 234 is provided with a via 234a, and at least a partial region of the atmospheric pressure sensing surface 40b is in communication with the airflow path through the via 234a.
Specifically, the side of the circuit board 234 facing away from the microphone mounting cavity 20c is located on the airflow path. The microphone 40 is mounted on the circuit board 234, the side of the microphone 40 away from the circuit board 234 is a negative pressure sensing surface 40a, and the side of the microphone 40 close to the circuit board 234 is an atmospheric pressure sensing surface 40b. The circuit board 234 is provided with the via 234a corresponding to the atmospheric pressure sensing surface 40b. That is, the microphone 40 is inverted, and the atmospheric pressure sensing surface 40b is in communication with the airflow path through the via 234a to be in communication with the outer side of the housing assembly 10. In this way, the atmospheric pressure can be maintained, and incorrect starting due to an impact by airflow is unlikely to occur.
In addition, sealing processing may also be performed on a connection point between the circuit board 234 and the base body 233. For example, a first sealing rib may be disposed between the end surface of the base body 233 and the end surface of the circuit board 234. Referring to FIG. 45 and FIG. 54, at a connection point between the base body 233 and the circuit board 234, a first sealing rib 235 is formed by a partial region of one of the end surface of the base body 233 and the end surface of the circuit board 234 protruding. That is, the first sealing rib 235 may be formed on the end surface of the base body 233 to be in sealing cooperation with the end surface of the circuit board 234, thereby improving the sealing effect at the connection point between the base body 233 and the circuit board 234. Certainly, the first sealing rib 235 may alternatively be formed on the end surface of the circuit board 234 to be in sealing cooperation with the end surface of the base body 233.
In an embodiment, the outer diameter of the microphone 40 may alternatively be slightly greater than the inner diameter of the microphone mounting cavity 20c, so that the sealing effect between the microphone 40 and the base body 233 is improved through an interference fit with the base body 233.
Referring to FIG. 43, the airflow path includes a first flow passage port 20a and a second flow passage port 20b disposed on the holder assembly 20. In the extension direction of the airflow path, the second flow passage port 20b is located downstream of the first flow passage port 20a, and a communication point between the microphone mounting cavity 20c and the airflow path is located upstream of the second flow passage port 20b.
As shown in FIG. 42 and FIG. 43, the airflow path is a channel for airflow to flow between the air inlet 10a and the air outlet 10b. The arrow in FIG. 42 represents the flow direction of the airflow. The first flow passage port 20a and the second flow passage port 20b are part of the airflow path, that is, the airflow flowing along the airflow path also passes through the first flow passage port 20a and the second flow passage port 20b. The extension direction of the airflow path is a direction extending from the air inlet 10a toward the air outlet 10b. The second flow passage port 20b is located downstream of the first flow passage port 20a, which means that the airflow flowing along the airflow path first passes through the first flow passage port 20a and then passes through the second flow passage port 20b.
The microphone mounting cavity 20c is in communication with a region of the airflow path upstream of the second flow passage port 20b. Therefore, the effect of forming negative pressure in the microphone mounting cavity 20c may be adjusted by adjusting a ratio of the cross-sectional area of the first flow passage port 20a to that of the second flow passage port 20b.
The cross-sectional area of the first flow passage port 20a is a minimum cross-sectional area of the airflow path, and the cross-sectional area of the second flow passage port 20b is not less than twice the cross-sectional area of the first flow passage port 20a and is a minimum cross-sectional area of a region of the airflow path downstream of the first flow passage port 20a.
Specifically, the first flow passage port 20a is a region having a minimum cross-sectional area in the airflow path, and the second flow passage port 20b is a region having a minimum cross-sectional area downstream of the first flow passage port 20a in the airflow path. The cross-sectional area of the second flow passage port 20b may be equal to twice the cross-sectional area of the first flow passage port 20a, or may be greater than twice the cross-sectional area of the first flow passage port 20a.
It should be noted that because the communication point between the microphone mounting cavity 20c and the airflow path and the first flow passage port 20a are both located upstream of the second flow passage port 20b, when a user performs puffing, a puffing force is formed for external airflow to flow in through the air inlet 10a and flow out from the air outlet 10b. Therefore, a larger cross-sectional area of the second flow passage port 20b and a smaller cross-sectional area of the first flow passage port 20a indicate larger negative pressure formed in the microphone mounting cavity 20c under the action of the puffing force.
Therefore, the second flow passage port 20b may have a larger cross-sectional area relative to the first flow passage port 20a by increasing the ratio of the cross-sectional area of the second flow passage port 20b to that of the first flow passage port 20a, and the communication point between the microphone mounting cavity 20c and the airflow path is located upstream of the second flow passage port 20b. Therefore, the effect of forming negative pressure in the microphone mounting cavity 20c during puffing can be improved, so that the microphone 40 disposed in the microphone mounting cavity 20c can conveniently sense a difference between internal pressure and external pressure of the microphone mounting cavity 20c, and it can be ensured that negative pressure sufficient for starting the microphone 40 is formed in the microphone mounting cavity 20c. In this way, the user can enable the microphone 40 to start when performing light puffing (that is, when the puffing force is small), thereby improving the starting sensitivity of the electronic vaporization device.
The shapes and specific sizes of the first flow passage port 20a and the second flow passage port 20b are not limited. For example, the first flow passage port 20a and the second flow passage port 20b are both square holes. The size of the first flow passage port 20a is 1.25 mm×1.25 mm, and the size of the second flow passage port 20b is 1.8 mm×1.8 mm. For another example, the cross-sectional area of the first flow passage port 20a is 1.44 mm².
It should be noted that the cross-sectional area of the first flow passage port 20a is greater than the cross-sectional area of the air inlet 10a, so that puffing resistance can be reduced, thereby facilitating puffing by a user.
In addition, the communication point between the microphone mounting cavity 20c and the airflow path and a relative position of the first flow passage port 20a are not limited. The communication point between the microphone mounting cavity 20c and the airflow path may be located between the air inlet 10a and the first flow passage port 20a, or may be located between the first flow passage port 20a and the second flow passage port 20b.
In an embodiment, referring to FIG. 43, the holder assembly 20 includes a battery holder 22 and a microphone mounting base 23 located between the battery holder 22 and the housing assembly 10. The battery holder 22 is a holder for mounting the battery of the electronic vaporization device.
For example, the battery holder 22 includes a first wall body, a second wall body, and a third wall body. The first wall body and the second wall body are disposed spaced apart, and the third wall body is located between the first wall body and the second wall body. The first flow passage port 20a is disposed in the first wall body, and the second flow passage port 20b is disposed in the second wall body. The first wall body, the second wall body, the third wall body, and the housing assembly 10 enclose jointly to form a first channel 20f. The first wall body is located on the side of the third wall body close to the air inlet 10a, and the second wall body is located on the side of the third wall body close to the air outlet 10b. The first wall body is provided with a threading hole in communication with an accommodating cavity and the airflow path to facilitate entry of a wire into the accommodating cavity. In addition, after the wire passes through the threading hole, sealing may be performed by applying sealant. Specifically, the first wall body, the second wall body, and the third wall body may be integrally formed or may be spliced.
In an embodiment, referring to FIG. 43, FIG. 46, FIG. 47, and FIG. 48, the airflow path includes the first channel 20f located upstream of the second flow passage port 20b. The holder assembly 20 is provided with a communication port 20e that establishes communication between the microphone mounting cavity 20c and the first channel 20f. The first channel 20f is provided with a bottom wall 21 on the side away from the air outlet 10b, and a partial region of the bottom wall 21 forms a liquid guide boss 211 that protrudes towards the first channel 20f, so that the liquid guide boss 211 protrudes with respect to another region of the bottom wall 21. The communication port 20e is disposed on the liquid guide boss 211. In this embodiment, the first flow passage port 20a and the communication port 20e are both disposed on the liquid guide boss 211. The heat conduction boss 211 is formed, so that a liquid flowing into the first channel 20f can be prevented from directly flowing into the microphone mounting cavity 20c through the communication port 20e, to avoid damage to the microphone 40.
In an embodiment, the first flow passage port 20a is provided in the liquid guide boss 211 and is located upstream of the communication port 20e for airflow flowing along the airflow path to flow along the top surface of the liquid guide boss 211 and flow through the communication port 20e.
Because both the communication port 20e and the first flow passage port 20a are provided in the liquid guide boss 211 and the first flow passage port 20a is located upstream of the communication port 20e, airflow flowing out from the first flow passage port 20a flows along the top surface of the liquid guide boss 211 and flows through the communication port 20e. Therefore, when the airflow path is located in a region between the first flow passage port 20a and the air inlet 10a and a liquid exists in the microphone mounting cavity 20c, part of the liquid flows upward into the first channel 20f under the action of a puffing force, and can be blown down the liquid guide boss 211 under the action of airflow flowing along the top surface of the liquid guide boss 211.
It should be noted that the aperture of the communication port 20e should not be excessively small, and processing is difficult when the aperture is excessively small. The aperture should not be excessively large either, and when the aperture is excessively large, the liquid in the airflow path tends to enter the microphone mounting cavity 20c through the communication port 20e. For example, the aperture of the communication port 20e is not less than 0.6 mm and not greater than 1 mm, and is, for example, 0.6 mm, 0.8 mm, or 1 mm.
Referring to FIG. 43, in an embodiment, the electronic vaporization device further includes liquid absorbing cotton 30 disposed in the first channel 20f. Specifically, the liquid absorbing cotton 30 can absorb the liquid in the first channel 20f, to prevent the liquid (for example, a to-be-vaporized liquid or a condensate that leaks out) in the first channel 20f from flowing into the microphone mounting cavity 20c to damage the microphone 40.
In addition, the arrangement height of at least a partial region of the liquid absorbing cotton 30 is less than the arrangement height of the top surface of the liquid guide boss 211. Therefore, when the electronic vaporization device is in a puffing state with the air outlet 10b facing upward, the height of the bottom end of the liquid absorbing cotton 30 can be less than the heights of the top ends of the first flow passage port 20a and the communication port 20e, so that a liquid in the first channel 20f can be better absorbed, thereby further reducing a possibility that the liquid in the first channel 20f enters the microphone mounting cavity 20c through the communication port 20e.
In an embodiment, referring to FIG. 43, FIG. 44, FIG. 45, and FIG. 54, the microphone mounting cavity 20c is disposed on the microphone mounting base 23. The microphone mounting base 23 is further provided with a second channel 23a. One end of the second channel 23a is in communication with the microphone mounting cavity 20c, and a communication point is located on the side of the negative pressure sensing surface 40a facing away from the air outlet 10b. The other end of the second channel 23a is in communication with the first channel 20f.
An end of the second channel 23a in communication with the microphone mounting cavity 20c is located on the side of the negative pressure sensing surface 40a facing away from the air outlet. Therefore, after the liquid enters the microphone mounting cavity 20c through the second channel 23a, the liquid does not contact the negative pressure sensing surface 40a, thereby avoiding damage to the microphone 40.
In addition, to further improve the effect of forming negative pressure in the microphone mounting cavity 20c in a puffing process, the sealing performance of the microphone mounting cavity 20c needs to be ensured, to prevent the microphone mounting cavity 20c from directly in communication with the outside in other regions of the microphone mounting cavity 20c apart from being in communication with the airflow path through the second channel 23a, so that it is difficult to form strong negative pressure in the microphone mounting cavity 20c. Referring to FIG. 45, FIG. 54, and FIG. 55, the battery holder 22 is provided with a communication port 20e that establishes communication between the first channel 20f and the second channel 23a. A second sealing rib 231 is disposed between the end surface of the microphone mounting base 23 and the end surface of the battery holder 22 at a communication point between the communication port 20e and the second channel 23a.
Specifically, the second sealing rib 231 may be formed on the end surface of the microphone mounting base 23, to be in sealing cooperation with the end surface of the battery holder 22, thereby improving the sealing effect at the communication point between the communication port 20e and the second channel 23a. Certainly, the second sealing rib 231 may alternatively be formed on the end surface of the battery holder 22, to be in sealing cooperation with the end surface of the microphone mounting base 23.
In an embodiment, a third sealing rib 232 is disposed between the end surface of the microphone mounting base 23 and the end surface of the housing assembly 10 at a connection point between the microphone mounting base 23 and the housing assembly 10. Specifically, the third sealing rib 232 may be formed on the end surface of the microphone mounting base 23, to be in sealing cooperation with the end surface of the housing assembly 10, thereby improving the sealing effect at a connection point between the microphone mounting base 23 and the housing assembly 10. Certainly, the third sealing rib 232 may alternatively be formed on the end surface of the housing assembly 10, to be in sealing cooperation with the end surface of the microphone mounting base 23.
In an embodiment, the outer diameter of the outer wall surface of a side of the battery holder 22 close to the microphone mounting base 23 is slightly greater than the inner diameter of the housing assembly 10, to improve the sealing effect between the battery holder 22 and the housing assembly 10 through an interference fit with the housing assembly 10.
Another embodiment of this application provides an electronic vaporization device, including a vaporization assembly 50 and the power supply assembly in any foregoing embodiment. The vaporization assembly 50 is disposed in the housing assembly 10, and is electrically connected to the microphone 40.
The vaporization assembly 50 is configured to vaporize a to-be-vaporized liquid to generate an aerosol to flow out of the air outlet 10b along with airflow flowing along the airflow path. When a user performs puffing through the air outlet 10b, a pressure difference is formed between the negative pressure sensing surface 40a and the atmospheric pressure sensing surface 40b of the microphone 40, and the microphone 40 is started, so that the vaporization assembly 50 operates to generate an aerosol. When the user stops puffing, atmospheric pressure is restored in the microphone mounting cavity 20c, the microphone 40 is not started, and the vaporization assembly 50 stops operating.
Referring to FIG. 56 to FIG. 58, FIG. 63 to FIG. 65, and FIG. 69 to FIG. 71, an embodiment of this application provides an electronic vaporization device 100/200/300, configured to heat a vaporization substrate to generate an aerosol for a user to use. The vaporization substrate includes, but is not limited to, a medical liquid or an oil made of a material for medical, wellness, health, or beauty purposes.
The electronic vaporization device 100/200/300 includes a vaporization assembly 110/210/310, a battery assembly 120/220/320, and a replenishment assembly 130/230/330. The vaporization assembly 110/210/310 stores a vaporization substrate, and the battery assembly 120/220/320 is electrically connected to the vaporization assembly 110/210/310 to supply power to the vaporization assembly 110/210/310. The vaporization assembly 110/210/310 may heat and vaporize the aerosol under the action of electric energy to generate an aerosol.
The replenishment assembly 130/230/330 is provided with an air outlet channel 130b/230b/330b allowing airflow to circulate and a replenishment chamber 130a/230a/330a configured to store the vaporization substrate. In a transportation and storage process, the replenishment assembly 130/230/330 and the vaporization assembly 110/210/310 may be separately placed. When the electronic vaporization device 100/200/300 is used, the replenishment assembly 130/230/330 may be mounted on the vaporization assembly 110/210/310. The aerosol generated by the vaporization assembly 110/210/310 may flow out through the air outlet channel 130b/230b/330b, and the replenishment chamber 130a/230a/330a is configured to supplement the vaporization assembly 110/210/310 with the vaporization substrate. In some other embodiments, an air outlet channel may alternatively be directly provided in the vaporization assembly 110/210/310. Therefore, when the replenishment assembly 130/230/330 is not mounted, puffing may be directly performed using the vaporization assembly 110/210/310. In some other embodiments, a suction nozzle 140/240/340 may further be mounted on the vaporization assembly 110/210/310, and the aerosol generated by the vaporization assembly 110/210/310 may flow out through the suction nozzle 140/240/340.
The vaporization assembly 110/210/310 includes a vaporization holder 112/212/312, a vaporization core 114/214/314, and a blocking member 115/215/315. The vaporization core 114/214/314 is located in the vaporization holder 112/212/312. The vaporization core 114/214/314 and the vaporization holder 112/212/312 jointly define a liquid storage chamber 110a/210a/310a configured to store the vaporization substrate. A liquid inlet channel 113a/213a/313a in communication with the liquid storage chamber 110a/210a/310a is provided in the vaporization holder 112/212/312. The blocking member 115/215/315 can be switched between a first position that blocks a liquid inlet of the liquid inlet channel 113a/213a/313a and a second position that opens the liquid inlet. When the replenishment assembly 130/230/330 is mounted on the vaporization holder 112/212/312, the blocking member 115/215/315 can be switched to the second position that opens the liquid inlet of the liquid inlet channel 113a/213a/313a.
It may be understood that, in some embodiments, after the replenishment assembly 130/230/330 is detachably mounted on the vaporization assembly 110/210/310, after the replenishment assembly 130/230/330 is used up, the current replenishment assembly 130/230/330 may be disassembled and replaced with a new replenishment assembly 130/230/330. In some other embodiments, when the replenishment assembly 130/230/330 is non-detachably mounted on the vaporization assembly 110/210/310, the replenishment assembly 130/230/330 cannot be disassembled from the vaporization assembly 110/210/310 after being mounted on the vaporization assembly 110/210/310.
Before the replenishment assembly 130/230/330 is mounted on the vaporization assembly 110/210/310, the blocking member 115/215/315 blocks the liquid inlet of the liquid inlet channel 113a/213a/313a. Therefore, the vaporization substrate in the liquid storage chamber 110a/210a/310a is kept from leaking through the liquid inlet channel 113a/213a/313a.
When the replenishment assembly 130/230/330 is mounted on the vaporization assembly 110/210/310, the blocking member 115/215/315 is moved to a position that opens the liquid inlet of the liquid inlet channel 113a/213a/313a. The replenishment chamber 130a/230a/330a is in communication with the liquid storage chamber 110a/210a/310a through the liquid inlet channel 113a/213a/313a. The vaporization substrate in the replenishment chamber 130a/230a/330a may flow into the liquid storage chamber 110a/210a/310a through the liquid inlet channel 113a/213a/313a.
In this way, in a transportation and storage process, the vaporization assembly 110/210/310 may be placed separately from the replenishment assembly 130/230/330, and the liquid inlet channel 113a/213a/313a of the vaporization assembly 110/210/310 is in a sealed state under blocking of the blocking member 115/215/315, thereby preventing the vaporization substrate from leakage and deterioration. When the electronic vaporization device 100/200/300 needs to be used, the liquid inlet of the vaporization assembly 110/210/310 is synchronously opened when the replenishment assembly 130/230/330 is mounted to establish communication with the replenishment assembly 130/230/330 quickly, thereby avoiding the risk of liquid leakage from the liquid storage chamber 110a/210a/310a.
Further, the liquid inlet of the liquid inlet channel 113a/313a is provided in the top surface or the side surface of the liquid inlet channel 113a/313a. The blocking member 115/315 is located in the liquid inlet channel 113a/313a in the first position to block the liquid inlet. In some other embodiments, the liquid inlet of the liquid inlet channel 213a is opened in the side surface of the liquid inlet channel 213a, and the blocking member 215 is sleeved outside the liquid inlet channel 213a to block the liquid inlet.
In some embodiments, the replenishment assembly 130/230 includes an abutting portion, and the abutting portion protrudes from the end surface of the replenishment assembly 130/230 that is in contact with the vaporization assembly 110/210. In some other embodiments, the vaporization assembly 310 includes an abutting portion, and the abutting portion protrudes from the end surface of the vaporization assembly 310 that is in contact with the replenishment assembly 330. When the replenishment assembly 130/230/330 is mounted on the vaporization assembly 110/210/310, the blocking member 115/215/315 pushed by the abutting portion to move to open the liquid inlet channel 113a/213a/313a.
It may be understood that the arrangement position and the forming manner of the abutting portion may be set as required, provided that the abutting portion can synchronously push the blocking member 115/215/315 to move to open the liquid inlet of the liquid inlet channel 113a/213a/313a when the replenishment assembly 130/230/330 is mounted on the vaporization assembly 110/210/310.
Referring to FIG. 58, FIG. 65, and FIG. 71, the vaporization holder 112/212/312 includes a holder main body 111/211/311. The holder main body 111/211/311 has a hollow, rotating body structure, and the direction of the central axis of the holder main body 111/211/311 is defined as a first direction (that is, a vertical direction in FIG. 58). The holder main body 111/211/311 includes an annular sleeve 1112/2112/3112 and a partition plate 1114/2114/3114 disposed at the axial end of the annular sleeve 1112/2112/3112. The annular sleeve 1112/2112/3112 and the partition plate 1114/2114/3114 jointly form an accommodating space for accommodating the vaporization core 114/214/314. Specifically, in some embodiments, the partition plate 1114/2114 is located outside the annular sleeve 1112/2112, and the outer diameter of the partition plate 1114/2114 is greater than the outer diameter of the annular sleeve 1112/2112. In some other embodiments, the partition plate 3114 is located inside the annular sleeve 3112. The vaporization core 114/214/314 is accommodated in the accommodating space formed by the holder main body 111/211/311, and the liquid storage chamber 110a/210a/310a configured to store the vaporization substrate is formed between the vaporization core 114/214/314 and the partition plate 1114/2114/3114.
Further, the holder main body 111/211/311 further includes a central tube 1116/2116/3116, one end of the central tube 1116/2116/3116 is connected to the partition plate 1114/2114/3114, the other end of the central tube 1116/2116/3116 extends along the first direction until being inserted into the vaporization core 114/214/314, and a central air passage 1116a/2116a/3116a that establishes communication between the vaporization core 114/214/314 and the replenishment assembly 130/230/330 is formed in the central tube 1116/2116/3116.
The vaporization core 114/214/314 includes a vaporization seat 1141/2141/3141, a top cover 1142/2142/3142, a heating member 1143/2143/3143, a positive conductive electrode 1144/2144/3144, and a negative conductive electrode 1145/2145/3145. The vaporization seat 1141/2141/3141 is fitted to the end of the holder main body 111/211/311 away from the partition plate 1114/2114/3114, and the top cover 1142/2142/3142 is fitted to the end of the vaporization seat 1141/2141/3141 facing the partition plate 1114/2114/3114. The vaporization seat 1141/2141/3141 and the top cover 1142/2142/3142 jointly define a vaporization chamber 114a/214a/314a. The liquid storage chamber 110a/210a/310a is formed between the top cover 1142/2142/3142 and the partition plate 1114/2114/3114 of the holder main body 111/211/311.
Further, the top cover 1142/2142/3142 includes a top-cover top wall and a top-cover side wall extending from the edge of the top-cover top wall in the direction away from the partition plate 1114/2114/3114. A top-cover central hole and at least one liquid delivery hole are opened in the top-cover top wall. The top-cover central hole is located at the central position of the top cover 1142/2142/3142 and is in communication with the vaporization chamber. An end of the central tube 1116/2116/3116 of the vaporization holder 112/212/312 may be inserted into the top-cover central hole, so that the central air passage 1116a/2116a/3116a of the vaporization holder 112/212/312 is in communication with the vaporization chamber. The liquid delivery hole is located at the outer periphery of the top-cover central hole, and is configured to establish communication between the vaporization chamber 114a/214a/314a and the liquid storage chamber 110a/210a/310a. The vaporization substrate in the liquid storage chamber 110a/210a/310a may flow into the vaporization chamber 114a/214a/314a through the liquid delivery hole.
The heating member 1143/2143/3143 is accommodated in the vaporization chamber 114a/214a/314a, and includes a substrate and a heating element. In some embodiments, the substrate may be formed from high-temperature-resistant porous materials such as ceramics, the heating element is formed on the surface of the substrate, and the heating element may generate heat under the effect of electric energy. One end of the positive conductive electrode 1144/2144/3144 and one end of the negative conductive electrode 1145/2145/3145 are electrically connected to the heating member 1143/2143/3143, and the other end of the positive conductive electrode 1144/2144/3144 and the other end of the negative conductive electrode 1145/2145/3145 are electrically connected to the battery assembly 120/220/320.
In some other embodiments, the heating member includes a heating element and liquid storage cotton wrapping the heating element, and the vaporization substrate in the liquid storage chamber 110a/210a/310a may be guided to the surface of the heating element through absorption by the liquid storage cotton.
In this way, the vaporization substrate in the liquid storage chamber 110a/210a/310a flows into the vaporization chamber 114a/214a/314a through the liquid delivery hole. The heating member 1143/2143/3143 in the vaporization chamber 114a/214a/314a absorbs the vaporization substrate, and generates heat under the action of electric energy of the battery assembly 120/220/320 to heat the vaporization substrate. The vaporization substrate is vaporized under heat to generate an aerosol, and the aerosol in the vaporization chamber 114a/214a/314a sequentially passes through the central air passage 1116a/2116a/3116a and the air outlet channel 130b/230b/330b to flow out. To ensure balance between the air pressure in the liquid storage chamber 110a/210a/310a and the external atmosphere, a ventilation channel in communication with the liquid storage chamber 110a/210a/310a is further formed in the top cover 1142/2142/3142. The ventilation channel may be formed in the top-cover side wall, or may be formed in the top-cover top wall. In some other embodiments, the ventilation channel may alternatively be formed between the heat-generating top cover 1142/2142/3142 and the heating member 1143/2143/3143.
Referring to FIG. 58, FIG. 59, and FIG. 60, a first embodiment of this application provides an electronic vaporization device 100. The vaporization holder 112 further includes two conduction members 113. The two conduction members 113 are disposed protruding from the side of the partition plate 1114 away from the liquid storage chamber 110a, and the two conduction members 113 are disposed spaced apart in the radial direction of the partition plate 1114. Each conduction member 113 includes a first conduction portion 1132 and a second conduction portion 1134 that are connected to each other. The first conduction portion 1132 is connected to the partition plate 1114. The first conduction portion 1132 has a hollow cylindrical structure. The liquid inlet channel 113a is formed in the first conduction portion 1132. The open end of the first conduction portion 1132 away from the partition plate 1114 forms the liquid inlet of the liquid inlet channel 113a, so that the liquid inlet is disposed on the top surface of the liquid inlet channel 113a. The second conduction portion 1134 is connected to the end of the first conduction portion 1132 away from the partition plate 1114. The second conduction portion 1134 extends from the inner side wall of the first conduction portion 1132 in the direction away from the partition plate 1114. The cross-section of the second conduction portion 1134 perpendicular to the first direction has a semi-circular arc shape. The second conduction portion 1134 is configured to extend into the replenishment assembly 130 to open the replenishment chamber 130a.
Two blocking members 115 are provided, and each blocking member 115 is a cylindrical structure whose shape and size match those of the liquid inlet channel 113a. Before the replenishment assembly 130 is mounted on the vaporization holder 112, each blocking member 115 is at least partially correspondingly embedded in one liquid inlet channel 113a, and the blocking member 115 has an interference fit with the liquid inlet channel 113a to close the liquid inlet of the liquid inlet channel 113a.
Before the replenishment assembly 130 is mounted on the vaporization holder 112, the blocking member 115 is at least partially embedded in the liquid inlet channel 113a formed by the first conduction portion 1132, and the blocking member 115 has an interference fit with the liquid inlet channel 113a to close the liquid inlet of the liquid inlet channel 113a, thereby preventing leakage of the vaporization substrate in the liquid storage chamber 110a. When the replenishment assembly 130 is mounted on the vaporization holder 112, the blocking member 115 is pushed by the replenishment assembly 130 to separate from the liquid inlet channel 113a to open the liquid inlet of the liquid inlet channel 113a, and the second conduction portion 1134 extends into the replenishment assembly 130 to open the replenishment chamber 130a. Therefore, the vaporization substrate in the replenishment chamber 130a may flow into the liquid storage chamber 110a through the liquid inlet channel 113a.
It may be understood that the number of the conduction members 113 and the number of the blocking members 115 are not limited thereto. In some other embodiments, one or more conduction members 113 and one or more blocking members 115 may be provided.
Further, the blocking member 115 is flexibly connected to the vaporization holder 112. Therefore, the blocking member 115 may be pushed by the replenishment assembly 130 to move to open the liquid inlet channel 113a.
Specifically, with reference to FIG. 58, FIG. 59, and FIG. 61, the vaporization assembly 110 further includes a blocking connection member 116, and the blocking connection member 116 and the two blocking members 115 are integrally formed and disposed. Specifically, the blocking connection member 116 has an annular structure. The blocking connection member 116 is sleeved over the central tube 1116 of the vaporization holder 112 to be fitted to the vaporization holder 112. The two blocking members 115 are respectively located at two opposite sides of the blocking connection member 116 in the radial direction, and each blocking member 115 is rotatably connected to the blocking connection member 116. In this way, the blocking member 115 is flexibly connected to the vaporization holder 112 by the blocking connection member 16. When the replenishment assembly 130 is mounted on the vaporization holder 112, the blocking member 115 is pushed by the replenishment assembly 130 to rotate with a connection point between the blocking member 115 and the blocking connection member 116 as a rotation center to separate from the liquid inlet channel 113a.
The blocking member 115 remains connected to the blocking connection member 116, and the blocking connection member 116 remains sleeved over the central tube 1116 of the vaporization holder 112. Therefore, the blocking member 115 that separates from the liquid inlet channel 113a can be prevented from floating in the liquid storage chamber 110a, the number of parts of the electronic vaporization device 100 is reduced, and the overall structure of the electronic vaporization device 100 is simplified.
Referring to FIG. 58, FIG. 59, and FIG. 60 again, the vaporization assembly 110 further includes two channel sealing members 117. The two channel sealing members 117 are sleeved over the first conduction portions 1132 of the two conduction members 113, respectively. When the replenishment assembly 130 is mounted on the vaporization holder 112, the second conduction portion 1134 is inserted into the replenishment assembly 130 and is in an interference fit with the replenishment assembly 130, thereby preventing the vaporization substrate from leaking through a gap between the sealing cover 133 and the vaporization holder 112. As a preferred implementation, the two channel sealing members 117 are integrally formed to be connected to each other, thereby reducing the number of parts of the electronic vaporization device 100, and simplifying the overall structure of the electronic vaporization device 100. In some other embodiments, the channel sealing member 117 may alternatively be disposed in the replenishment assembly 130. When the replenishment assembly 130 is mounted on the vaporization holder 112, the second conduction portion 1134 may be inserted into the channel sealing member 117 and has an interference fit with the channel sealing member 117.
As shown in FIG. 58 and FIG. 59, the replenishment assembly 130 includes a replenishment housing and a sealing member 134. The replenishment housing includes an outer ring shell 131, an inner ring shell 132, and a sealing cover 133. The outer ring shell 131 has a hollow cylindrical structure open at one end, and the central axis of the outer ring shell 131 extends along the first direction. The inner ring shell 132 extends from the closed end of the outer ring shell 131 to the open end of the outer ring shell 131 in the first direction. An air outlet channel 130b extending in the first direction is formed in the inner ring shell 132, one end of the air outlet channel 130b extends through the closed end of the outer ring shell 131 to be in communication with the external atmosphere, and the other end of the air outlet channel 130b is in communication with the central air passage 1116a of the vaporization holder 112. In some other embodiments, the central air passage 1116a may not be disposed in the replenishment assembly 130, and is only configured to store the vaporization substrate. The aerosol generated by the vaporization assembly 110 flows out through the vaporization assembly 110 itself.
The sealing cover 133 has a rotating body structure. The sealing cover 133 is mounted at the open end of the outer ring shell 131 and is disposed outside the inner ring shell 132. The outer ring shell 131, the inner ring shell 132, and the sealing cover 133 jointly form the replenishment chamber 130a surrounding the inner ring shell 132 in a circumferential direction. Two communication holes 1331 in communication with the replenishment chamber 130a are opened through the sealing cover 133, and the two communication holes 1331 are provided spaced apart in the radial direction of the sealing cover 133, and the central axis of each communication hole 1331 extends along the first direction. Each communication hole 1331 includes a first communication end 1331a and a second communication end 1331b that are in communication with each other. The first communication end 1331a is located on the side of the second communication end 1331b close to the sealed end of the outer ring shell 131, and the inner diameter of the second communication end 1331b is greater than or less than the inner diameter of the first communication end 1331a.
When the replenishment assembly 130 is mounted on the vaporization holder 112, the first conduction portion 1132 of the conduction member 113 may extend into the replenishment chamber 130a through the first communication end 1331a. The second conduction portion 1134 of the conduction member 113 is located in the second communication end 1331b. A conduction sealing member 134 sleeved over the second conduction portion 1134 is located in the second communication end 1331b. The conduction sealing member 134 is in interference fit with the second conduction portion 1134 and the second communication end 1331b, to close a gap between the conduction member 113 and the hole wall of the communication hole 1331. In another embodiment, the channel sealing member 117 is disposed in the second communication end 1331b. When the replenishment assembly 130 is mounted on the vaporization holder 112, the second conduction portion 1134 may be inserted into the channel sealing member 117.
Further, the sealing cover 133 is further provided with an abutting portion 1333 configured to push the blocking member 115. When the replenishment assembly 130 is mounted on the vaporization holder 112, the blocking member 115 is pushed by the abutting portion 1333 to move to open the liquid inlet channel 113a.
Specifically, one end of the abutting portion 1333 is connected to the inner wall of the first communication end 1331a of the communication hole 1331, the other end of the abutting portion 1333 passes through the second communication end 1331b along the first direction to extend out of the communication hole 1331, and the cross-section of the abutting portion 1333 perpendicular to the first direction has a semi-circular arc shape.
As shown in FIG. 58, FIG. 59, and FIG. 62, two sealing members 134 are provided. The sealing members 134 are mounted on the sealing cover 133. Each sealing member 134 is a cylindrical structure whose shape and size match those of the first communication end 1331a of the communication hole 1331.
Each sealing member 134 is at least partially correspondingly embedded in the first communication end 1331a of one communication hole 1331 before the vaporization assembly 110 is mounted on the replenishment assembly 130, and the sealing member 134 has an interference fit with the communication hole 1331 to block the communication hole 1331. When the replenishment assembly 130 is mounted on the vaporization holder 112, the conduction member 113 passes through the communication hole 1331 to extend into the replenishment chamber 130a, and the sealing member 134 is located in the liquid inlet channel 113a and is pushed by the second conduction portion 1134 of the conduction member 113 to separate from the communication hole 1331. Therefore, the vaporization substrate in the replenishment chamber 130a may enter the liquid inlet channel 113a through the communication hole 1331.
Further, the vaporization assembly 110 further includes a sealing connection member 135, and the sealing connection member 135 and the two sealing members 134 are integrally formed and disposed. Specifically, the sealing connection member 135 includes an inner connection ring 1352, an outer connection ring 1354, and a connection arm 1356 connected between the inner connection ring 1352 and the outer connection ring 1354. The inner connection ring 1352 has a hollow annular structure to be sleeved over the inner ring shell 132, and the outer connection ring 1354 has a hollow annular structure to surround an edge of the sealing cover 133. The two sealing members 134 are respectively connected to two opposite sides of the outer connection ring 1354 in the radial direction. In this way, the sealing member 134 is flexibly mounted on the sealing cover 133 through the sealing connection member 135. When the replenishment assembly 130 is mounted on the vaporization assembly 110, the sealing member 134 is pushed by the conduction member 113 to rotate with a connection point between the sealing member 134 and the sealing connection member 135 as a rotation center to separate from the communication hole 1331.
Because the sealing member 134 remains connected to the sealing connection member 135, the sealing member 134 can be prevented from floating in the replenishment chamber 130a after separating from the communication hole 1331, thereby reducing the number of parts of the electronic vaporization device 100, and simplifying the overall structure of the electronic vaporization device 100.
The fitting principle of the vaporization assembly 110 and the replenishment assembly 130 of the first embodiment is as follows:
Before the replenishment assembly 130 is mounted on the vaporization assembly 110, in the vaporization assembly 110, the blocking member 115 is embedded in the first conduction portion 1132 of the conduction member 113, and the blocking member 115 has an interference fit with the first conduction portion 1132 to block the liquid inlet of the liquid inlet channel 113a. In the replenishment assembly 130, the sealing member 134 is embedded in the first communication end 1331a of the communication hole 1331 of the sealing cover 133, and the sealing member 134 has an interference fit with the first communication end 1331a to block the communication hole 1331.
When the replenishment assembly 130 is mounted on the vaporization assembly 110, the conduction member 113 of the vaporization assembly 110 passes through the communication hole 1331 of the sealing cover 133 to extend into the replenishment chamber 130a, and the sealing member 134 is pushed by the conduction member 113 to rotate to separate from the communication hole 1331. In addition, the abutting portion 1333 of the sealing cover 133 passes through the liquid inlet channel 113a to extend into the liquid storage chamber 110a, the blocking member 115 is pushed by the abutting portion 1333 to rotate to separate from the liquid inlet channel 113a, and the channel sealing member 117 is located in the second communication end 1331b of the communication hole 1331 and has an interference fit with the second communication end 1331b. Therefore, the replenishment chamber 130a and the liquid storage chamber 110a are in communication with each other through the liquid inlet channel 113a, the vaporization substrate in the replenishment chamber 130a may enter the liquid storage chamber 110a through the liquid inlet channel 113a, and air exchange may also be performed between the replenishment chamber 130a and the liquid storage chamber 110a to balance air pressure.
In the foregoing mounting process, because the replenishment chamber 130a and the liquid storage chamber 110a are simultaneously in communication, the risk of liquid leakage generated because the liquid storage chamber 110a is first in communication with the atmosphere can be avoided.
Referring to FIG. 65 and FIG. 66, a second embodiment of this application provides an electronic vaporization device 200.
With reference to FIG. 65, FIG. 66, and FIG. 67, the vaporization holder 212 further includes two conduction members 213. The two conduction members 213 are disposed protruding from the side of the partition plate 2114 away from the liquid storage chamber 210a, and the two conduction members 213 are disposed spaced apart in the radial direction of the partition plate 2114. Each conduction member 213 has a hollow cylindrical structure. The liquid inlet channel 213a is formed in the conduction member 213, and the liquid inlet of the liquid inlet channel 213a is located on the side surface of the liquid inlet channel 213a away from the liquid storage chamber 210a. Two blocking members 215 are also provided. Each blocking member 215 has a hollow cylindrical structure, and each blocking member 215 is sleeved on the conduction member 213.
Before the vaporization holder 212 is mounted on the replenishment assembly 230, the blocking member 215 is sleeved at the end of the conduction member 213 away from the partition plate 2114 and closes the liquid inlet of the liquid inlet channel 213a. Therefore, the vaporization substrate in the liquid storage chamber 210a can be prevented from flowing out through the liquid inlet channel 213a. When the replenishment assembly 230 is mounted on the vaporization holder 212, the end of the conduction member 213 provided with the liquid inlet of the liquid inlet channel 213a extends into the replenishment chamber 230a, and the blocking member 215 is pushed by the replenishment assembly 230 to slide along the first direction to the end of the conduction member 213 close to the liquid storage chamber 210a to open the liquid inlet of the liquid inlet channel 213a. Therefore, the vaporization substrate in the replenishment chamber 230a may flow into the liquid storage chamber 210a through the liquid inlet channel 213a.
Further, when the blocking member 215 is pushed by the replenishment assembly 230 to slide to the end of the conduction member 213 close to the liquid storage chamber 210a, the blocking member 215 has an interference fit with the conduction member 213 and the replenishment assembly 230 to close a gap between the conduction member 213 and the replenishment assembly 230.
Still referring to FIG. 65 and FIG. 66, the structure of the replenishment assembly 230 of the electronic vaporization device 200 of the second embodiment is approximately the same as that of the replenishment assembly 130 in the first embodiment, and includes a replenishment housing, a sealing member 234, and a sealing connection member 135. The replenishment housing includes an outer ring shell 231, an inner ring shell 232, and a sealing cover 233. An air outlet channel 230b is formed in the inner ring shell 232, and the outer ring shell 231, the inner ring shell 232, and the sealing cover 233 jointly form a replenishment chamber 230a. A communication hole 2331 in communication with the replenishment chamber 230a is opened in the sealing cover 233. Each communication hole 2331 includes a first communication end 2331a and a second communication end 2331b that are in communication with each other. The sealing connection member 135 and the sealing member 134 are integrally formed and disposed, and the sealing member 134 is flexibly mounted on the sealing cover 133 through the sealing connection member 135.
A difference between the replenishment assembly 230 of the second embodiment and the replenishment assembly 130 of the first embodiment lies in that the inner diameter of the second communication end 2331b of the sealing cover 233 of the replenishment assembly 230 is greater than or less than the inner diameter of the first communication end 2331a, and a step surface is formed between the first communication end 2331a and the second communication end 2331b to serve as an abutting portion for abutting against the blocking member 215.
In this way, when the replenishment assembly 230 is mounted on the vaporization holder 212, the conduction member 213 may pass through the first communication end 2331a to extend into the replenishment chamber 230a. Under abutting by the step surface (that is, the abutting portion) formed between the first communication end 2331a and the second communication end 2331b, the blocking member 215 is kept in the second communication end 2331b and has an interference fit with the second communication end 2331b, thereby providing a sealing function while the liquid inlet channel 213a is in communication, and preventing the vaporization substrate from flowing out from a gap between the vaporization holder 212 and the replenishment assembly 230.
The fitting principle of the vaporization assembly 210 and the replenishment assembly 230 of the second embodiment is as follows:
Before the replenishment assembly 230 is mounted on the vaporization assembly 210, in the vaporization assembly 210, the blocking member 215 is sleeved on the conduction member 213 to close the liquid inlet of the liquid inlet channel 213a. In the replenishment assembly 230, the sealing member 234 is embedded in the first communication end 2331a of the communication hole 2331 of the sealing cover 233, and the sealing member 234 has an interference fit with the first communication end 2331a to block the communication hole 2331.
When the replenishment assembly 230 is mounted on the vaporization assembly 210, the conduction member 213 of the vaporization assembly 210 passes through the communication hole 2331 of the sealing cover 233 to extend into the replenishment chamber 230a, the sealing member 234 is pushed by the conduction member 213 to rotate to separate from the communication hole 2331, and the blocking member 215 is kept in the second communication end 2331b under abutting by the step surface in the communication hole 2331 of the sealing cover 233 and has an interference fit with the second communication end 2331b. Therefore, the replenishment chamber 230a and the liquid storage chamber 210a are in communication with each other through the liquid inlet channel 213a, the vaporization substrate in the replenishment chamber 230a may enter the liquid storage chamber 210a through the liquid inlet channel 213a, and air exchange may also be performed between the replenishment chamber 230a and the liquid storage chamber 210a to balance air pressure.
In the foregoing mounting process, because the replenishment chamber 230a and the liquid storage chamber 210a are simultaneously in communication, the risk of liquid leakage generated because the liquid storage chamber 210a is first in communication with the atmosphere can be avoided.
Referring to FIG. 71, FIG. 72, and FIG. 73, a third embodiment of this application provides a vaporization assembly 310.
Two conduction members 313 are provided. The two conduction members 313 are provided protruding from the side of the partition plate 3114 away from the liquid storage chamber 310a, and the two conduction members 313 are disposed spaced apart in the radial direction of the partition plate 3114. Each conduction member 313 includes at least one conduction portion 3132. Specifically, in an embodiment, each conduction member 313 includes two conduction portions 3132, the two conduction portions 3132 are disposed spaced apart in the radial direction of the vaporization holder 312 (as shown in FIG. 77), a liquid inlet channel 313a is formed between the two conduction portions 3132, and the height of one conduction portion 3132 protruding from the holder main body 311 is greater than the height of the other conduction portion 3132 protruding from the holder main body 311. The width of the end of the conduction portion 3132 having a larger height away from the holder main body 311 gradually decreases from the end of the conduction portion 3132 close to the holder main body 311 to the end of the conduction portion 3132 away from the holder main body 311 to form a pyramidal structure. It may be understood that the number of the conduction members 313 is not limited thereto. In some other embodiments, only one conduction member 313 may be provided, or a plurality of conduction members 313 may be provided.
When the replenishment assembly 330 is mounted on the vaporization holder 312, the two conduction portions 3132 sequentially contact the replenishment assembly 330 and pierce the replenishment assembly 330 for the replenishment chamber 230a to be in communication with the liquid inlet channel 313a. Therefore, the vaporization substrate in the replenishment chamber 230a may flow into the liquid storage chamber 310a through the liquid inlet channel 313a.
With reference to FIG. 72, FIG. 73, FIG. 78, and FIG. 79, the vaporization assembly 310 further includes an abutting portion 316. The abutting portion 316 has a generally T-shaped structure, including a connecting end 3161 and an abutting end 3163. The connecting end 3161 has a rod-like structure extending in the first direction. The abutting end 3163 and the blocking member 315 are disposed at two opposite ends of the connecting end 3161, respectively, and cross-sectional areas of the abutting end 3163 and the blocking member 315 are both greater than the cross-sectional area of the connecting end 3161. The abutting end 3163 extends out of the liquid inlet channel 313a through a gap between the two conduction portions 3132.
When the replenishment assembly 330 is mounted on the vaporization holder 312, because the two conduction portions 3132 are disposed spaced apart, the abutting end 3163 is located between the two conduction portions 3132 and abuts against the holder main body 311.
In this way, before the replenishment assembly 330 is mounted on the vaporization holder 312, the blocking member 315 is located in the liquid inlet channel 313a to block the liquid inlet. When the replenishment assembly 330 is mounted on the vaporization holder 312, the conduction member 313 pierces the replenishment assembly 330, the abutting portion 316 moves under abutting by the replenishment assembly 330 until the abutting end 3163 abuts against the partition plate 3114 of the holder main body 311, and the blocking member 315 is driven by the abutting portion 316 to separate from the liquid inlet channel 313a to enter the liquid storage chamber 310a. A gap exists between the connecting end 3161 of the abutting portion 316 and the liquid inlet channel 313a. Therefore, the vaporization substrate in the replenishment chamber 230a flows between the connecting end 3161 and the wall surface of the liquid inlet channel 313a into the liquid storage chamber 310a, and the connecting end 3161 may guide the flow of the vaporization substrate. In addition, the blocking member 315 is limited with respect to the holder main body 311 through the abutting end 3163 of the abutting portion 316. Therefore, the blocking member 315 is prevented from separating from the holder main body 311 and floating in the liquid storage chamber 310a.
Further, the vaporization assembly 310 further includes a piercing portion 317. The piercing portion 317 is disposed on the side of the abutting end 3163 of the abutting portion 316 away from the connecting end 3161. The cross-sectional area of the piercing portion 317 gradually decreases from the position close to the abutting end 3163 to the position away from the abutting end 3163. When the replenishment assembly 330 is mounted on the vaporization holder 312, the piercing portion 317 and the conduction member 313 may pierce the sealing cover 333 together.
Further, in some embodiments, the blocking member 315, the abutting portion 316, and the piercing portion 317 are integrally formed and disposed (as shown in FIG. 78). In some other embodiments, as shown in FIG. 79, the blocking member 315 includes a blocking member body 3152 and a sealing ring 3154 sleeved outside the blocking member body 3152. The blocking member body 3152, the blocking member 315, and the abutting portion 316 are integrally formed and disposed, and the sealing ring 3154 is sleeved outside the blocking member body 3152 to have an interference fit with the replenishment assembly 330.
With reference to FIG. 74 and FIG. 75, in an embodiment, a curved extended ventilation groove 3142a is opened in the outer surface of the top-cover side wall. One end of the ventilation groove 3142a is connected to the end portion of the end of the top-cover side wall away from the liquid storage chamber 310a, and the other end of the ventilation groove 3142a is bent and extends to the middle position of the top-cover side wall. A ventilation hole 3142b in communication with the liquid storage chamber 310a is opened in the groove bottom wall of the ventilation groove 3142a. The ventilation groove 3142a and the ventilation hole 3142b jointly form a ventilation channel. Therefore, air outside the top cover 3142 may enter the liquid storage chamber 310a through the ventilation channel. Further, a sealing rib 3142c surrounding the ventilation groove 3142a is further disposed protruding from the top-cover side wall, and the sealing rib 3142c may abut against the vaporization holder 312 to close the ventilation channel.
In another embodiment, with reference to FIG. 77, an air inlet hole 3142d in communication with the liquid storage chamber 310a is opened in the top-cover top wall. The vaporization assembly 310 further includes a ventilation valve plate 3146. The ventilation valve plate 3146 is rotatably mounted on the top cover 3142, and the ventilation valve plate 3146 is located in the liquid storage chamber 310a and covers the air inlet hole 3142d. In this way, when external atmospheric pressure is greater than air pressure in the liquid storage chamber 310a, the external atmospheric pressure pushes the ventilation valve plate 3146 to rotate to open the air inlet hole 3142d. Therefore, external airflow may flow into the liquid storage chamber 310a through the air inlet hole 3142d. When an action force exerted by the oil film absorption force in the liquid storage chamber 310a, the gravity of the e-liquid, and the air pressure in the liquid storage chamber 310a together on the ventilation valve plate 3146 is equal to an action force exerted by the external atmospheric pressure on the ventilation valve plate 3146, the ventilation valve plate 3146 covers the air inlet hole 3142d again to close the liquid storage chamber 310a, thereby implementing a unidirectional communication function.
Still referring to FIG. 72 and FIG. 73, the replenishment assembly 330 includes an outer ring shell 331, an inner ring shell 332, and a sealing cover 333. The outer ring shell 331 has a hollow cylindrical structure open at one end, and the central axis of the outer ring shell 331 extends along the first direction. The inner ring shell 332 extends from the closed end of the outer ring shell 331 to the open end of the outer ring shell 331 in the first direction. An air outlet channel 230b extending in the first direction is formed in the inner ring shell 332, one end of the air outlet channel 230b extends through the closed end of the outer ring shell 331 to be in communication with the external atmosphere. The sealing cover 333 is formed by a pierceable structure, for example, a metal film. The sealing cover 333 is mounted at the open end of the outer ring shell 331 and is sleeved outside the inner ring shell 332.
In this way, the outer ring shell 331, the inner ring shell 332, and the sealing cover 333 jointly form the replenishment chamber 230a surrounding the inner ring shell 332 in a circumferential direction. When the replenishment assembly 330 is mounted on the vaporization holder 312, the conduction member 313 pierces the sealing cover 333, and the abutting portion 316 is pushed by the sealing cover 333 to drive the blocking member 315 to move to open the liquid inlet channel 313a.
As a preferred implementation, the sealing cover 333 is provided with two pierceable regions, an edge of each pierceable region is correspondingly disposed with an edge of one of the conduction members 313, and the thickness of the edge of the pierceable region is less than the thickness of another region of the sealing cover 333, so that the sealing cover 333 can be smoothly pierced by the conduction members 313. The central position of the pierceable region corresponds to the blocking member 315, and the thickness of the region is thick. Therefore, the conduction member 313 may be pushed to move downward to open the liquid inlet channel 313a.
As shown in FIG. 76 and FIG. 77, two guide rails 3312 are disposed protruding from the outer side wall of the replenishment assembly 330, the two guide rails 3312 are disposed on two opposite sides of the replenishment assembly 330 in the radial direction of the replenishment assembly 330, and each guide rail 3312 extends lengthwise along the first direction. The two guide slots 3112a are opened in the vaporization holder 312, the two guide slots 3112a are disposed on two opposite sides of the vaporization holder 312 in the radial direction of the vaporization holder 312, and each guide slot 3112a extends lengthwise along the first direction. It may be understood that the number and shapes of the guide rails 3312 and the number and shapes of the guide slots 3112a are not limited thereto, and may be set as required to satisfy different requirements.
Based on the arrangement of the guide rail 3312 and the guide slot 3112a, the electronic vaporization device 300 has a first mounting state and a second mounting state. When the electronic vaporization device 300 is in the first mounting state, the end portion of an end of the guide rail 3312 abuts against an edge of the vaporization holder 312, and the vaporization assembly 310 and the replenishment assembly 330 are rotatable with respect to each other. When the guide rail 3312 is aligned with the guide slot 3112a, the end of the replenishment assembly 330 provided with the guide rail 3312 may be inserted into the vaporization assembly 310 along the first direction, and the guide rail 3312 is inserted into the guide slot 3112a along the first direction, thereby limiting relative positions of the vaporization assembly 310 and the replenishment assembly 330 in the circumferential direction, and ensuring accurate alignment of the conduction member 313 and the pierceable regions of the sealing cover 333.
In some embodiments, at least one elastic fastener 3314 is further provided protruding from the outer side wall of the replenishment assembly 330, and at least one locking slot matching the elastic fastener 3314 is opened in the inner side wall of the vaporization holder 312. When the replenishment assembly 330 is mounted on the vaporization assembly 310, the elastic fastener 3314 may be snapped into the locking slot, so that the replenishment assembly 330 and the vaporization assembly 310 are relatively fixed.
As a preferred implementation, the length of the guide rail 3312 is greater than the height of the conduction member 313 protruding from the holder main body 311. When the end portion of an end of the guide rail 3312 abuts against an edge of the vaporization holder 312, the distance between the end surface of the end of the replenishment assembly 330 that is configured to contact the vaporization assembly 310 and the end surface of the end of the vaporization assembly 310 that is configured to contact the replenishment assembly 330 is greater than the protruding height of the conduction member 313, and the end portion of the conduction member 313 facing the sealing cover 333 is in a suspended state, thereby preventing the sealing cover 333 and the conduction member 313 from being in contact with each other in a process of relative rotation of the replenishment assembly 330 and the guide rail 3312, and ensuring that the conduction member 313 can be completely inserted into the replenishment assembly 330.
In some embodiments, a sealing ring 336 is further embedded outside the outer ring shell 331 of the replenishment assembly 330. When the replenishment assembly 330 is mounted on the vaporization assembly 310, the sealing ring 336 has an interference fit with the inner wall of the vaporization holder 312 to close a gap between the sealing ring 336 and the inner wall of the vaporization holder 312. As a preferred implementation, an avoidance groove 3112b extending in the circumferential direction is formed in the inner side wall of the holder main body 311 of the vaporization holder 312. When the end portion of the end of the guide rail 3312 abuts against the edge of the vaporization holder 312, the portion of the sealing ring 336 protruding from the outer ring shell 331 is located in the avoidance groove 3112b, so that the vaporization assembly 310 and the replenishment assembly 330 can freely rotate with respect to each other, thereby facilitating mutual plugging of the guide rail 3312 and the guide slot 3112a.
With reference to FIG. 74 and FIG. 80, the battery assembly 320 includes a battery holder 321, a bottom cover 322, a battery 323, a mainboard 324, a sensing unit 325, an air passage liquid absorbing member 326, and a conductive contact pin 327. The battery holder 321 has a hollow housing-like structure. An end of the battery holder 321 is fitted to the end of the vaporization assembly 310 away from the replenishment assembly 330. A battery accommodating cavity and an air inlet passage that are adjacently disposed are formed in the battery holder 321, and a holder air inlet 321a that establishes communication between the air inlet passage and the vaporization assembly 310 is opened. The bottom cover 322 is fitted to the end of the battery holder 321 away from the vaporization assembly 310. A mainboard accommodating cavity is formed between the battery holder 321 and the bottom cover 322. A bottom-cover air inlet hole that establishes communication between the mainboard accommodating cavity and the external atmosphere is opened in the bottom cover 322. The mainboard 324 and the sensing unit 325 are both accommodated in the mainboard 324 accommodating cavity. The battery 323 is accommodated in the battery 323 accommodating cavity. The air passage liquid absorbing member 326 is accommodated in the air inlet passage. The conductive contact pin 327 is inserted in the end portion of the end of the battery holder 321 facing the vaporization assembly 310, and is electrically connected to the battery 323.
In this way, the battery 323 is electrically connected to the heating member 3143 of the vaporization assembly 310 by the conductive contact pin 327. When a user puffs on the electronic vaporization device 300, airflow in the external atmosphere sequentially passes through the bottom-cover 322 air inlet hole, the mainboard 324 accommodating cavity, the air inlet passage, and the holder air inlet 321a to enter the vaporization chamber 314a. In this process, the sensing unit 325 may sense a change in an air pressure difference to send a sensing signal to the mainboard 324. The mainboard 324 may control the battery 323 based on the sensing signal to supply power to the vaporization assembly 310 to heat the vaporization substrate.
In some embodiments, at least one positioning column 3212 is disposed protruding from the end surface of the end of the battery holder 321 facing the vaporization assembly 310, and a positioning hole matching the positioning column 3212 is further opened in the vaporization seat 3141 of the vaporization assembly 310. When the vaporization assembly 310 and the battery assembly 320 are fitted with each other, the positioning column 3212 is inserted into the positioning hole, thereby implementing circumferential positioning of the vaporization seat 3141 and the battery holder 321. Further, at least one magnetic attraction member 3214 is further embedded in the end surface of the end of the battery holder 321 facing the vaporization assembly 310. The magnetic attraction member 3214 may attract the vaporization seat 3141 for the battery holder 321 and the vaporization seat 3141 to be connected to each other.
The fitting principle of the vaporization assembly 310 and the replenishment assembly 330 of the third embodiment is as follows:
Before the replenishment assembly 330 is mounted on the vaporization assembly 310, in the vaporization assembly 310, the blocking member 315 is inserted into the liquid inlet channel 313a, and a second blocking portion 3154 of the blocking member 315 blocks the liquid inlet channel 313a. In the replenishment assembly 330, the sealing cover 333 closes the replenishment chamber 230a.
When the replenishment assembly 330 is mounted on the vaporization assembly 310, an end of the replenishment assembly 330 is first inserted into the vaporization assembly 310, and the end portion of the end of the guide rail 3312 abuts against the edge of the vaporization holder 312. The vaporization assembly 310 and the replenishment assembly 330 are rotatable with respect to each other in a circumferential direction. When the guide rail 3312 is aligned with the guide slot 3112a, the replenishment assembly 330 may be further inserted into the vaporization assembly 310. In a process in which the guide rail 3312 and the guide slot 3112a are plugged with each other, the first conduction portion 3132, the blocking member 315, and a second conduction portion 3134 sequentially pierce the sealing cover 333 of the replenishment assembly 330, and the blocking member 315 is pushed by the sealing cover 333 to move. The second blocking portion 3154 is pushed by the replenishment assembly 330 to separate from the liquid inlet channel 313a to enter the liquid storage chamber 310a. A gap exists between the first blocking portion 3152 and the wall surface of the liquid inlet channel 313a. The vaporization substrate in the replenishment chamber 230a flows into the liquid storage chamber 310a from between the first blocking portion 3152 and the wall surface of the liquid inlet channel 313a.
According to the foregoing electronic vaporization device 100/200/300, the detachable replenishment assembly 130/230/330 is disposed, so that the vaporization assembly 110/210/310 and the replenishment assembly 130/230/330 may be separately transported and stored. Liquid leakage is unlikely to occur in a transportation and storage process, and the liquid storage chamber 110a/210a/310a of the vaporization assembly 110/210/310 may be synchronously in communication with the replenishment chamber 130a/230a/330a of the replenishment assembly 130/230/330 when the replenishment assembly 130/230/330 is mounted on the vaporization assembly 110/210/310, thereby improving usability and recyclability of the electronic vaporization device 100/200/300, and effectively preventing liquid leakage under the action of external atmospheric pressure when the liquid storage chamber 110a/210a/310a is opened.
The technical features in the foregoing embodiments may be randomly combined. For simplicity of description, all possible combinations of the technical features in the foregoing embodiments are not described. However, it should be considered that these combinations of technical features fall within the scope recorded in the specification provided that these combinations of technical features do not have any conflict.
