The housing structure (101) is provided with a liquid storage tank (13), a vent channel (16), and an atomization channel (15). The liquid storage tank (13) is used for storing an aerosol substrate. Two ends of the atomization channel (15) are communicated with external air. One end of the vent channel (16) is communicated with the atomization channel (15), and the other end of the vent channel (16) can be communicated with the liquid storage tank (13) so as to release pressure of the liquid storage tank (13). The housing structure (101) is further provided with storage cavities (332, 333, 334) formed in the inner wall of the vent channel (16).

The present invention provides an atomizing device, which can store a certain amount of liquid aerosol matrix and heat the aerosol matrix to atomize it into aerosol for users to inhale.

The atomization device includes an atomization assembly 100 and a power supply assembly connected to each other. The power supply assembly and the atomization assembly can be fixedly connected or detachably connected by magnetic attraction, snap connection, etc., which is not limited here.

When the power supply assembly is connected to the atomization assembly 100, the power supply assembly can supply power to the atomization assembly 100, so that the atomization assembly 100 can heat and atomize the stored aerosol matrix into an aerosol.

1, 2 and 3, the atomization assembly 100 includes a housing structure 101 and a heating structure 102, wherein the heating structure 102 is disposed inside the housing structure 101. The housing structure 101 is used to store an aerosol matrix, and the heating structure 102 is used to heat the aerosol matrix and atomize it into an aerosol.

Referring to Figure 3, the shell structure 101 includes an outer shell 1, a packaging member 2, a guide member 3, a middle member 4, a base 5 and a bottom shell 6, wherein the packaging member 2 is sleeved on the guide member 3, the guide member 3 is connected to the middle member 4, the middle member 4 is connected to the base 5, the base 5 is connected to the bottom shell 6, and the bottom shell 6 is detachably connected to the outer shell 1 to encapsulate the packaging member 2, the guide member 3, the middle member 4 and the base 5 inside the outer shell 1.

It can be understood that in other embodiments, the nozzle 11 can also be in other shapes, such as a cylindrical or elliptical shape, which is not limited here.

The outer shell 1 has first snap-fit flanges 12 on both sides of the end portion close to the bottom shell 6, and the first snap-fit flanges 12 are used to snap-fit with the bottom shell 6 to connect the outer shell 1 to the bottom shell 6.

The housing 1 is provided with a ventilation column 14, which is provided with an air outlet channel 141, which passes through both ends of the ventilation column 14 and is arranged close to the central axis of the housing 1. The air outlet channel 141 communicates with the heating structure 102 and the outside of the housing 1, so that the aerosol generated by the heating structure 102 can flow out to the outside of the housing 1 through the air outlet channel 141 for inhalation by the user.

Referring to Fig. 4, the package 2 is provided with a first sealing ring 21 and a second sealing ring 22 along its circumference, and the first sealing ring 21 and the second sealing ring 22 are arranged at intervals up and down. The first sealing ring 21 and the second sealing ring 22 abut against the inner wall of the liquid storage bin 13 to seal the inner wall of the liquid storage bin 13 to prevent the aerosol matrix in the liquid storage bin 13 from flowing out from the inner wall thereof. It can be understood that in other embodiments, the number of sealing rings can also be set to three or more, so that the effect of sealing the inner wall of the liquid storage bin 13 is better.

The package 2 is hollow, that is, a first accommodating cavity 23 is provided therein. The package 2 is made of silicone material, so that the package 2 has good elasticity and sealing ability. When the package 2 is sleeved on the guide member 3, the guide member 3 is located in the first accommodating cavity 23 of the package 2.

The package 2 is provided with a liquid outlet hole 24 and a first through hole 25, the liquid outlet hole 24 connects the first accommodating chamber 23 and the liquid storage tank 13, and the aerosol matrix in the liquid storage tank 13 can flow to the first accommodating chamber 23 through the liquid outlet hole 24. There are two liquid outlet holes 24, which are respectively located on both sides of the first through hole 25. It can be understood that in other embodiments, one, three or more liquid outlet holes 24 can be provided, which is not limited here.

The first through hole 25 is sealed and plugged with the vent column 14 (as shown in FIG. 2 ) to prevent the aerosol matrix in the liquid storage bin 13 from leaking out. The vent column 14 has an air outlet channel 141 that is connected to the first accommodating chamber 23 .

5 and 6 , the guide member 3 is provided with a second through hole 31, which is hollow with two ends open. The two ends of the second through hole 31 are connected to the first through hole 25 and the heating structure 102 respectively, and the aerosol generated by the heating structure 102 can flow into the air outlet channel 141 through the second through hole 31 and the first through hole 25 in sequence.

The guide member 3 is provided with a guide channel 32, both ends of which penetrate the guide member 3, one end of the guide channel 32 is connected to the liquid outlet 24, and the other end is connected to the heating structure 102. Therefore, the liquid storage tank 13 is connected to the liquid outlet 24, the guide channel 32, and the heating structure 102 in sequence, and the aerosol matrix in the liquid storage tank 13 can flow to the heating structure 102 through the liquid outlet 24 and the guide channel 32 in sequence, so that the heating structure 102 can heat the aerosol matrix flowing over and atomize it into aerosol.

The inner wall of the guide channel 32 is partially inclined, namely, the guide slope 321. The lower end of the guide slope 321 is close to the heating structure 102, so that the aerosol matrix can flow to the heating structure 102 more easily through the guiding effect of the guide slope 321. There are two guide channels 32, which are respectively located on both sides of the second through hole 31. In other embodiments, one, three or more guide channels 32 can be provided, which is not limited here.

The outer wall of the guide member 3 has four airway units 33, and two airway units 33 are arranged on each side of the guide member 3. It can be understood that in other embodiments, the number of airway units 33 arranged on the guide member 3 can also be one, two, three, five or more than five, which is not limited here.

Each airway unit 33 is connected to the liquid storage tank 13 and the heating structure 102. Since the heating structure 102 is connected to the air outside the housing 1 through the second through hole 31, the first through hole 25, and the air outlet channel 141, the airway unit 33 is connected to the air outside the housing 1, that is, the liquid storage tank 13 is connected to the external air through the airway unit 33. As the heating structure 102 heats and atomizes the aerosol matrix, the aerosol matrix in the liquid storage tank 13 gradually decreases, and the negative pressure formed in the liquid storage tank 13 can be released through the airway unit 33 in turn, so that the aerosol matrix in the liquid storage tank 13 can continue to flow to the heating structure 102 by its own gravity.

In addition, the airway unit 33 can also store a certain amount of liquid. When the aerosol generated by the heating structure 102 flows to the airway unit 33 and liquefies to form condensate, the condensate can be stored in the airway unit 33, and the airway unit 33 can still continue to connect the liquid storage tank 13 and the external air, and the liquid storage tank 13 can continue to release pressure.

The airway unit 33 includes a pressure relief channel 331 and a first storage chamber 332, a second storage chamber 333, a third storage chamber 334 and a vent 335 connected to the pressure relief channel 331. The pressure relief channel 331 is connected to the liquid storage tank 13 and the vent 335. The vent 335 is connected to the external air so that the liquid storage tank 13 can be depressurized. The first storage chamber 332, the second storage chamber 333 and the third storage chamber 334 are arranged in an upper and lower interval. The condensate formed after the aerosol is liquefied in the pressure relief channel 331 can be stored in the first storage chamber 332, the second storage chamber 333 and the third storage chamber 334. Since the first storage chamber 332, the second storage chamber 333 and the third storage chamber 334 are not on the extension path of the pressure relief channel 331, even if multiple storage chambers store condensate, the pressure relief channel 331 will not be blocked, and the liquid storage tank 13 can still be connected to the external air. It should be emphasized that the number of the above-mentioned storage cavities is not limited, and one, two, four or more than four storage cavities may be provided, which is not limited here.

A ventilation cavity 34 is formed on a side of the flow guide member 3 facing away from the flow guide channel 32 , and the ventilation cavity 34 is connected to the vent 335 and the external air.

The guide member 3 also has second clamping flanges 35 on both sides. The second clamping flanges 35 are used for detachably clamping with the base 5 .

7 and 8 , an air flow hole 41 is provided in the middle portion of the middle piece 4 . The air flow hole 41 penetrates the middle piece 4 along the thickness direction. The air flow hole 41 allows external air to flow into the middle piece 4 .

An airflow groove 42 is provided in the middle of the intermediate member 4 around the airflow hole 41 , and external air can flow into the airflow groove 42 through the airflow hole 41 , and then flow from the airflow groove 42 to the heating structure 102 to bring out the aerosol generated by the heating structure 102 .

Two first mounting holes 43 are formed at the bottom of the air flow groove 42. The two first mounting holes 43 penetrate the middle member 4 and are respectively used for two electrode rods 9 (shown in FIG. 3 ) to be inserted and fixed. The two electrode rods 9 are one positive and one negative. One end of the two electrode rods 9 is electrically connected to the heating structure 102, and the other end is exposed to the outside and is used to connect to the battery in the power supply assembly, so that the battery supplies power to the heating structure 102 through the two electrode rods 9 to make the heating structure 102 generate heat.

The left and right ends of the middle piece 4 are both provided with middle holes 44 , and the middle hole 44 penetrates the middle piece 4 . The middle hole 44 communicates with the ventilation cavity 34 and the base 5 .

A receiving groove 45 is provided on one side of the middle piece 4 facing away from the airflow groove 42 . The receiving groove 45 can be used to receive a part of the electrode rod, so as to facilitate the positioning and installation of the electrode rod and also provide more airflow space.

9 , first clamping holes 51 are formed on both sides of the base 5 , and the first clamping holes 51 are detachably clamped with the second clamping flanges 35 of the guide member 3 .

The base 5 is also provided with a first air pressure balance groove 52 and a second air pressure balance groove 53. There are two first air pressure balance grooves 52 and two second air pressure balance grooves 53. The two first air pressure balance grooves 52 are respectively located on the left and right sides of the base 5, and the two second air pressure balance grooves 53 are respectively located on the left and right sides of the base 5. The first air pressure balance groove 52 and the second air pressure balance groove 53 located on the same side of the base 5 are arranged at intervals and are connected to each other. When the base 5 is engaged with the guide member 3, the base 5 and the guide member 3 can clamp and fix the middle member 4 in the middle, and the first air pressure balance groove 52 is connected to the middle hole 44.

The base 5 is also provided with nine air inlet holes 54 arranged in an array. It is understood that the number of the air inlet holes 54 can also be other numbers, and the arrangement can be arranged in other ways, such as a ring array, which is not limited here.

The air inlet hole 54 runs through the base 5 and is connected to the second air pressure balance groove 53, so the liquid storage tank 13 can be connected to the external air through the pressure release channel 331, the air vent 335, the ventilation cavity 34, the middle hole 44, the first air pressure balance groove 52, the second air pressure balance groove 53, and the air inlet hole 54 in sequence, thereby being depressurized, and the aerosol matrix in the liquid storage tank 13 can flow smoothly to the heating structure 102 by its own gravity.

It should be emphasized that the receiving groove 45 of the intermediate member 4 is at a certain distance from the top of the first air pressure balance groove 52 and the second air pressure balance groove 53, and the middle hole 44 and the air inlet hole 54 are both connected to the receiving groove 45. Therefore, even if the first air pressure balance groove 52 and the second air pressure balance groove 53 are filled with condensate, the connection between the middle hole 44 and the outside air will not be blocked, and the connection between the liquid storage tank 13 and the outside air will not be affected.

The base 5 is also provided with two second mounting holes 55, and the two second mounting holes 55 are respectively connected to the two first mounting holes 43, and one end of the two electrode rods 9 can be sequentially passed through the first mounting hole 43 and the second mounting hole 55 and exposed to the outside. When the power supply assembly is connected to the atomizer assembly 100, the two electrode rods 9 are electrically connected to the battery of the power supply assembly.

The base 5 is provided with a mounting groove 56 along its circumference, and a sealing ring 57 is sleeved in the mounting groove 56. The sealing ring 57 is made of silica gel and is used to abut against the inner wall of the bottom shell 6 to prevent air leakage inside the base 5.

3 , a second accommodating cavity 61 is provided in the bottom shell 6 , and one end is closed and the other end is open. The second accommodating cavity 61 is used to accommodate the base 5 , and the sealing ring 57 on the base 5 is tightly attached to the cavity wall of the second accommodating cavity 61 to ensure the sealing of the base 5 .

Second clamping holes 62 are formed on both sides of the bottom shell 6 , and the second clamping holes 62 are used to be clamped and matched with the first clamping flange 12 of the outer shell 1 , so as to encapsulate multiple other components.

Referring to FIG. 2 and FIG. 3 , the heating structure 102 includes a heating body 7, a gasket 8 and the two electrode rods 9 mentioned above, and the heating body 7 is arranged between the gasket 8 and the two electric shock rods 9. One end of the two electrode rods 9 is respectively connected to the positive electrode and the negative electrode of the heating body 7. The gasket 8 is made of silicone, and can also be made of other elastic materials. The two ends of the gasket 8 respectively abut the flanges of the heating body 7 and the guide member 3 to prevent the heating body 7 from directly contacting the guide member 3.

A third through hole 81 is formed through the middle portion of the gasket 8, and the third through hole 81 connects the heater 7 and the guide channel 32 of the guide member 3, so that the aerosol matrix can flow to the heater 7 through the third through hole 31, and then the heater 7 can heat the aerosol matrix and atomize it into an aerosol after being powered on.

The middle part of the electrode rod 9 is provided with a positioning protrusion 91 (shown in FIG. 3 ) along its circumference, and the positioning protrusion 91 is clamped in the receiving groove 45 of the middle piece 4. The middle piece 4 cooperates with the base 5 to clamp the positioning protrusion 91, thereby positioning the electrode rod 9. When the electrode rod 9 is fixed, the electrode rod 9 cooperates with the gasket 8 to clamp and fix the heating body 7.

10 , it should be emphasized that there is a certain gap between the heating body 7 and the inner wall of the flow guide 3 , and the gap connects the air flow hole 41 and the air outlet channel 141 . The aerosol generated by the heating body 7 can flow out from the air outlet channel 141 .

Referring to FIG. 11 , FIG. 11 shows a main schematic diagram of the airway of the present invention. It is worth noting that the above-mentioned air inlet hole 54, air flow hole 41, air flow groove 42, second through hole 31, and air outlet channel 141 together constitute the atomization channel 15. It can be understood that the length extension direction of the atomization channel 15 is arranged parallel to the length extension direction of the housing 1, and both ends of the atomization channel are connected to the external air of the housing 1. When the user sucks the mouthpiece 11 with his mouth, the external air can enter the atomization channel through the air inlet hole 54, and the air flow is mixed with the aerosol generated by the heating body 7, and then enters the user's mouth through the air outlet channel 141.

The second air pressure balance groove 53, the first air pressure balance groove 52, the middle hole 44, the ventilation cavity 34, the vent 335, and the pressure release channel 331 form a ventilation channel 16. It can be understood that one end of the ventilation channel 16 is connected to the liquid storage tank 13, and the other end is connected to the atomization channel 15. Since the atomization channel 15 is connected to the outside air, the ventilation channel 16 is connected to the outside air, and the pressure of the liquid storage tank 13 is released.

The flow guide 3 further includes a one-way valve 36, one end of which is rotatably connected to the side wall of the flow guide 3, and the free end of the one-way valve 36 can only rotate toward the inside of the liquid storage bin 13. A torsion spring (not shown in the figure) can be arranged at the position where the one-way valve 36 is rotatably connected. In a natural state, the torsion spring can drive the one-way valve 36 to close the outlet of the liquid storage bin 13 through elastic force.

When the user sucks the nozzle 11, the atomization channel 15 is in a negative pressure state, and the atomization channel 15 is connected to the ventilation channel 16, so the ventilation channel 16 is also in a negative pressure state. Since the one-way valve 36 cannot rotate toward the outside of the liquid storage tank 13, the outlet of the liquid storage tank 13 is still in a closed state. The heating body 7 can be made of ceramic material, and ceramics have natural pores. In addition, the heating body 7 is connected to the liquid storage tank 13, and the atomization channel 15 can have a certain suction force on the liquid storage tank 13 through the pores of the heating body 7. Coupled with the gravity of the aerosol matrix 10 itself, the aerosol matrix 10 can flow more to the heating body 7 and be atomized into an aerosol by the heating body 7.

As the aerosol matrix in the liquid storage bin 13 gradually decreases, the negative pressure in the liquid storage bin 13 gradually increases, until the one-way valve 36 is driven to overcome the elastic force of the torsion spring and rotate toward the inside of the liquid storage bin 13, so that the liquid storage bin 13 is connected with the ventilation channel 16, and the air in the ventilation channel 16 enters the liquid storage bin 13 to release the pressure of the liquid storage bin 13. The negative pressure in the liquid storage bin 13 gradually decreases until it tends to be balanced, so that the aerosol matrix 10 in the liquid storage bin 13 can continue to flow into the heating body 7 by its own gravity.

The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
