Specific Embodiments

In order to facilitate understanding of the present application, the following is a more detailed description of the present application in conjunction with the accompanying drawings and specific embodiments.
An example of the present application proposes an electronic vaporization device, which may include an atomizer 100 that stores and vaporizes a liquid substrate to generate an aerosol, and a power supply mechanism 200 that powers the atomizer 100, as shown in FIG. 1.
In an optional implementation, as illustrated in FIG. 1, the power supply mechanism 200 includes a receiving cavity 270 disposed at one end along the length direction for receiving at least a portion of the atomizer 100, and an electrical contact 230 that is at least partially exposed on the surface of the receiving cavity 270. This electrical contact is used to form an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and housed within the power supply mechanism 200, thereby powering the atomizer 100.
According to the preferred implementation shown in FIG. 1, the atomizer 100 is provided with an electrical contact 21 on the end opposite to the power supply mechanism 200 along the length direction, so as to establish a conductive connection between the atomizer 100 and the power supply mechanism 200 by contacting the electrical contact 230 when at least a portion of the atomizer 100 is received within the receiving cavity 270.
A seal 260 is provided within the power supply mechanism 200. This seal separates at least a portion of the interior space of the power supply mechanism 200 to form the aforementioned receiving cavity 270. In the preferred implementation shown in FIG. 1, the seal 260 is configured to extend in the cross-sectional direction of the power supply mechanism 200. It is preferably made of a flexible material, such as silicone gel. This prevents the liquid substrate that may seep from the atomizer 100 into the receiving cavity 270 from flowing towards internal components of the power supply mechanism 200, such as the controller 220 and sensor 250 etc.
In the preferred implementation shown in FIG. 1, the power supply mechanism 200 also includes a battery cell 210 for power supply, located at the end opposite to the receiving cavity 270 along the length direction. It also includes a controller 220 positioned between the battery cell 210 and the receiving cavity 270. This controller 220 operably directs electrical current between the battery cell 210 and the first electrical contact 230.
During use, the power supply mechanism 200 comprises a sensor 250 for detecting the suction airflow generated when the atomizer 100 is inhaled. The controller 220 then controls the battery cell 210 to output current to the atomizer 100 based on the detection signal from this sensor 250.
In a further preferred implementation shown in FIG. 1, the power supply mechanism 200 is equipped with a charging interface 240 at the end opposite to the receiving cavity 270, used for charging the battery cell 210.
FIGS. 2-5 show a structural schematic diagram of one example of the atomizer 100 from FIG. 1, including a housing that comprises:
A main body 10; as shown in FIGS. 2-5, this main body 10 is roughly shaped like a flat cylinder. The main body 10 has a proximal end 110 and a distal end 120 opposite each other along the length direction. According to typical usage requirements, the proximal end 110 is configured as the end from which the user inhales the aerosol, with an inhalation port 113 provided at the proximal end 110 for user inhalation. The distal end 120 is designed to connect with the power supply mechanism 200, and the distal end 120 of the main body 10 is open, allowing for the installation of necessary functional components inside the main body 10. The open end of the main body 10 is fitted with a removable end cap 20 to seal the distal end 120 of the main body 10. The main body 10 and the end cap 20 together define the outer casing or housing of the atomizer 100. As well as in certain implementations, the primary housing 10 and/or end cap 20 is rigid, e.g., may include hard metal or polymer plastic.
Further, in the example illustrated in FIGS 2-4, the electrical contact 21 extends from the surface of the end cap 20 to the interior of the atomizer 100, with at least part of it exposed outside the atomizer 100, thereby forming a conductive connection with the electrical contact 230 through contact. Additionally, an air inlet 22 is provided on the end cap 20 to allow external air to enter the atomizer 100 during inhalation.
Also, further referring to FIGS 2-4, the primary housing 10 includes:
Portion 111 and portion 112; wherein portion 111 is near or defines the proximal end 110, and portion 112 is near or defines the distal end 120.
Additionally, the width dimension of portion 111 adjacent to portion 112 is greater than the width dimension of portion 112; and the thickness dimension of portion 111 adjacent to portion 112 is greater than the thickness dimension of portion 112. During assembly, portion 112 is received or inserted into the receiving cavity 270 of the power source mechanism 200; and portion 111 is exposed or located outside the receiving cavity 270 of the power source mechanism 200. Furthermore, when portion 112 of the atomizer 100 is received or housed within the receiving cavity 270 of the power source mechanism 200, portion 111 abuts the power source mechanism 200 near the end of the receiving cavity 270 to form a stop.
Further, as shown in FIGS 3-5, the interior of the primary housing 10 is provided with a liquid storage cavity 12 for storing a liquid substrate and an atomization assembly for drawing the liquid substrate from the liquid storage cavity 12 and heating the atomized liquid substrate. Wherein, the atomization assembly generally includes a capillary liquid guide element for drawing the liquid substrate, and a heating element bonded to the liquid guide element, which heats at least a portion of the liquid substrate in the guide element to generate an aerosol during power-up. In optional implementations, the liquid guide element includes flexible fibers, such as cotton fibers, non-woven fabrics, fiberglass ropes, etc., or includes porous materials with a microporous structure, such as porous ceramics or porous glass. The heating element may be bonded to the liquid guide element by printing, deposition, sintering, or physical assembly, or wrapped around the liquid guide element.
Further, in implementations shown in FIGS 3-5, the atomization assembly comprises: A porous body 30 for absorbing and delivering a liquid substrate, and a heating element 40 for heating and vaporizing the liquid substrate absorbed by the porous body 30. Additionally, in the cross-sectional structure schematic shown in FIG 5, an aerosol output tube 11 is provided axially within the main housing 10; a liquid storage cavity 12 is also provided within the main housing 10 for storing the liquid substrate. In this implementation, the aerosol output tube 11 extends at least partially into the liquid storage cavity 12, and the liquid storage cavity 12 is formed by the space between the outer wall of the aerosol output tube 11 and the inner wall of the main housing 10. The first end of the aerosol output tube 11, at the relatively proximal end 110, communicates with the suction port 113. The second end, at the relatively distal end 120, is in airflow connection with the atomization chamber 340 formed between the atomization face 320 of the porous body 30 and the end cap 20. This allows the aerosol generated by the heating element 40 vaporizing the liquid substrate and released into the atomization chamber 340 to be transported to the suction port 113 for inhalation.
Further referring to the structure of the porous body 30 shown in FIGS 3, 4, 5, and 6, the shape of the porous body 30 may be generally, but not limited to, a block structure in this embodiment. According to the preferred design of this embodiment, it includes an arched shape with an atomization face 320 facing the end cap 20 along the axial direction of the main housing 10. During use, the side of the porous body 30 opposite the atomization face 320 is in fluid communication with the liquid storage cavity 12, allowing it to absorb the liquid substrate. The microporous structure within the porous body 30 then conducts the liquid substrate to the atomization face 320 for heating and atomization to form an aerosol, which is then released or emitted from the atomization face 320.
In certain implementations, the porous body 30 may be made of a hard capillary structure such as porous ceramic, porous glass-ceramic, porous glass, or the like. The heating element 40 is preferably a conductive track formed on the atomization face 320 by sintering a resistive paste after printing, ensuring that all or most of its surface is tightly bonded to the atomization face 320. Alternatively, in other variations of the implementation, the heating element 40 can be obtained by bonding a sheet or mesh-like resistive substrate to the atomization face 320. Of course, in some examples, the heating element 40 may be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium metal etc.
Naturally, the heating element 40 is formed on the atomization face 320; and after assembly, the electrical contact 21 abuts the heating element 40, thereby powering the heating element 40.
Referring further to FIGS. 3-5, to assist in sealing the liquid storage cavity 12, a stent 60 and a flexible sealing element 70 are also provided within the primary housing 10; the sealing element 70 seals the exposure of the liquid storage cavity 12. The flexible sealing element 70 is disposed at least in part between the liquid storage cavity 12 and the stent 60, and its profile is adapted to the cross-section of the silhouette within the primary housing 10, thereby providing a seal to the liquid storage cavity 12 to prevent leakage of the liquid substrate from the liquid storage cavity 12. To further prevent contract deformation of the flexible material sealing element 70 from affecting the tightness of the seal, support is provided to the above stent 60 by being housed within the flexible sealing element 70.
Further referring to FIGS. 3-5, to assist in securing the installation of the porous body 30, the rigid stent 60 has a retention space 64 away from the liquid storage cavity 12 and the porous body 30 is received and held within the retention space 64 of the stent 60. and further comprising:
A flexible sealing element 50 arranged between the porous body 30 and the stent 60; the flexible sealing element 50 is generally cartridge in the form of a hollow cylinder, the interior hollow for holding the porous body 30 and is mounted out of the porous body 30 by a tight arrangement.
The rigid stent 60, in turn, holds the porous body 30 with the flexible sealing element 50 in place, which in some examples may include a circular shape that is generally open to the lower end, the retention space 64 being used to accommodate and retain the flexible sealing element 50 and porous body 30. The flexible sealing element 50 may seal the crevices between the porous body 30 and the stent 60 to prevent the liquid substrate from seeping out of the crevices between them in one aspect; on the other hand, the flexible sealing element 50 is located between the porous body 30 and the stent 60, which is advantageous for the porous body 30 to be stably housed within the stent 60 to avoid loosening.
As well as in certain implementations, the stent 60 is rigid; and, the stent 60 includes at least one of an organic polymer, plastic, ceramic, metal, and the like. As well, the flexible sealing element 70 includes at least one of a silicone, rubber, or thermoplastic elastomer. As well, the flexible sealing element 50 includes at least one of a silicone, rubber, or thermoplastic elastomer.
See further FIGS. 3-5, in order to ensure the smooth transmission of liquid substrate and the output of aerosols, a pilot hole 71 for liquid substrate circulation is provided on the flexible sealing element 70, a pilot channel 61 is provided on the stent 60, and a pilot hole 51 is provided on the flexible sealing element 50. The liquid substrate within the liquid storage cavity 12 in use flows to the porous body 30 through the pilot hole 71, the pilot channel 61, and the pilot hole 51 in turn, as shown by arrow R1 in FIGS. 4 and 5, which is then transferred to the atomization surface 320 after absorption and vaporized, and the generated aerosol is released into the atomization chamber 340 defined between the atomization surface 320 and the end cap 20.
As well, after assembly, the sealing element 70 seals the liquid storage cavity 12 at least partially supported by the stent 60 and allows the liquid substrate within the liquid storage cavity 12 to exit only from the pilot hole 71.
On the output path of the aerosol during suction, see arrow R2 in FIGS. 3 and 4, a first socket 72 is provided on the flexible sealing element 70 with the lower end of the supply aerosol output pipe 11, a second socket 62 is provided on the corresponding stent 60, and a window 63 is provided on the opposite side of the main housing 10 with the atomization surface 320 in airflow communication with the second socket 62. After installation, the complete suction airflow path is shown in FIGS 3 and 4 by arrow R2, the external air enters the atomization chamber 340 via the air inlet 22 on the end cap 20 and the generated aerosol is subsequently transported from the window 63 to the second receptacle 62 and output to the aerosol output pipe 11 through the first receptacle 72.
With reference to the implementation shown in FIG. 6, the porous body 30 is shaped in an arcuate shape and has a sidewall 31 and sidewall 32 in a width direction that is reverse, and a bottom wall 33 extending between the sidewall 31 and sidewall 32; the lower surface of the bottom wall 33 is configured as an atomizing surface 320. And the sidewalls 31 and 32 are extending in a length direction of the porous body 30, thereby defining a liquid channel 34 extending in a length direction of the porous body 30 between the sidewalls 31, the sidewall 32, and the bottom wall 33, and receiving and absorbing a liquid substrate under flow by the pilot hole 71, the guide channel 61, and the pilot hole 51 through the liquid channel 34.
Further shown in accordance with FIG. 6, the porous body 30 further includes a top wall 35 extending in a cross-sectional direction of the atomizer 100 between the sidewalls 31, 32. Wherein, the top wall 35 and the bottom wall 33 are arranged in reverse in a height direction of the porous body 30. For example, as shown in FIG. 6, the bottom wall 33 is arranged in a lower end of the height direction of the porous body 30 and the top wall 35 is arranged in an upper end of the height direction of the porous body 30. As well, the extension length of the top wall 35 in the direction of the length of the porous body 30 is less than the extension length of the bottom wall 33.
As well, the top wall 35 is a central portion proximate the porous body 30 length direction. In the direction of the height of the porous body 30, the liquid channel 34 has an opening 341 that is not blocked on both sides of the top wall 35; upon assembly, the opening 341 is opposite the pilot hole 71 and/or the guide channel 61 and/or the pilot hole 51, thereby allowing the liquid channel 34 to receive a liquid substrate under the flow from the pilot hole 51 through the opening 341.
With further reference to FIGS. 3-4, the sealing element 50 is generally cartridge-shaped in a hollow manner, the interior hollow being used to accommodate and encase the receiving cavity of the porous body 30, which is then assembled to wrap around the porous body 30. The sealing element 50 is provided with a number of convex tendons 52 for lifting the sealing effect after installation, which are primarily crevices between the stent 60 and the porous body 30 to prevent leakage from the crevice between the stent 60 and the porous body 30 during liquid transfer; therefore, in implementations, the convex tendons 52 are collectively connected to form an annular ring and are surrounded or surrounded by the pilot hole 51, thereby achieving a relatively good sealing effect. As well as in certain implementations, the convex tendons 52 are arranged on the peripheral wall and the upper end wall of the sealing element 50; and, the convex tendons 52 are surrounded or bounded by at least one closed ring surrounding the pilot hole 51.
As well, after assembly, an interference mating region of the porous body 30 with an inner surface of the retention space 64 of the stent 60 is defined by the convex tendons 52, which in turn lift the seal; in an embodiment, the convex tendons 52 is at least partially squeezed or compressed by the porous body 30 and the stent 60.
As well, the stent 60 is supported and retained by the end cap 20 upon assembly.
Also shown further in FIGS. 7-10, the primary housing 10 of the atomizer 100 is further arranged in:
The identification element 13, provides a visual indication of the color associated with the unique nature of atomizer 100.
The identification element 13 has an identifiable color that allows the identification element 13 to have a color associated with unique properties to provide an indication or identification, thereby facilitating identification of the unique properties of the atomizer 100 by a user or a color sensor within the power supply mechanism 200. Or, for example, in certain implementations, the power source mechanism 200 includes a color sensor to detect the color of the identification element 13, thereby determining the unique properties of the atomizer 100.
In certain specific implementations, the unique properties of the atomizer 100 above may include flavors of spices contained in the liquid substrate, such as peach, mint, orange. For example, in certain specific implementations, the identification element 13 has a color associated with the flavor of the spice contained in the liquid substrate, e.g., the identification element 13 has a yellow color that identifies or indicates a liquid substrate containing the orange flavor, or the identification element 13 has a green color that identifies or indicates a liquid substrate containing the mint flavor, etc., to identify or indicate the flavor of the spice contained in the liquid substrate, respectively.
In certain specific implementations, for example, the above unique properties may include the strength of the nicotine contained in the liquid substrate, e.g., the content of the nicotine.
In certain specific implementations, for example, the above unique properties may include a maximum capacity of the liquid storage cavity 12, such as 2mL/3mL, in atomizer 100.
In certain specific implementations, for example, the above unique properties may include the most appropriate vaporization power or vaporization temperature of the liquid substrate in atomizer 100.
In certain specific implementations, for example, the above unique properties may include at least one of a viscosity, specific heat, boiling point, or vaporization efficiency of the liquid substrate in atomizer 100.
For example, in some specific implementations, the above unique properties may include at least one of an initial resistance value, a TCR value, an optimum heating power, etc., of the heating element 40 in atomizer 100.
As well as in certain implementations, the identification element 13 has a color that is different from the portion 111 and/or portion 112 of the primary housing 10. For example, in certain implementations, the portion 111 and/or portion 112 of the primary housing 10 is black or transparent; and the identification element 13 is at least one of yellow, green, red, blue, purple, or other colors.
In implementations shown in FIGS 7-10, the identification element 13 is an annular shape around the primary housing 10. Additionally, the identification element 13 is arranged at an incline.
Specifically, the atomizer 100 includes a first side 130 and a second side 140 that diverge in the thickness direction; and the identification element 13 is in an annular shape inclined from the first side 130 to the second side 140.
As shown in FIG 7, the identification element 13 forms an angle α with the central axis or longitudinal axis m of the atomizer 100; and in certain implementations, the angle α is between 50° and 80°.
As shown in FIGS 7-10, the identification element 13 is arranged around or bonded to portion 112 of the primary housing 10 and positioned against or adjacent to portion 111. After assembly, the outer surface of the identification element 13 is neatly joined or flush with the outer surface of the portion 112 adjacent to portion 111.
As shown in FIGS 7-10, the cross-section of the identification element 13 along the longitudinal direction of atomizer 100 is flat. Specifically, as shown in FIGS 9 and 10, the cross-section of the identification element 13 along the longitudinal direction of the atomizer 100 has a first dimension d1 extending in the longitudinal direction of the atomizer 100; and the cross-section of the identification element 13 along the longitudinal direction of the atomizer 100 has a second dimension d2 extending perpendicular to the longitudinal direction of atomizer 100; the first dimension d1 is greater than the second dimension d2.
For example, in some specific implementations, the first dimension d1 is between 1 - 4 mm; and the second dimension d2 is between 0.2 - 2 mm.
Also, as further shown in FIGS. 7-10, the width and/or thickness of the portion 112 of the primary housing 10 is constant; and, the identification element 13 has a lower side surface 131 that dives away from the portion 111 in an axial direction and is defined between the lower side surface 131 and the surface of the portion 112 of the primary housing 10 to form an abutting step; and thus the lower side surface 131 of the identification element 13 is abutting the power source mechanism 200 when the portion 112 of the primary housing 10 is received within the receiving cavity 270 of the power source mechanism 200. The lower side surface 131, which defines the step, is also in an angled arrangement relative to the longitudinal direction of the atomizer 100 or cross-section of the primary housing 10 and/or portion 112 with the angled angle.
As well as when the atomizer 100 is received in the power supply mechanism 200, the identification element 13 is exposed or exposed outside the power supply mechanism 200; and when the atomizer 100 is received in the power supply mechanism 200, the identification element 13 is visible.
In certain implementations, the identification element 13 is independently prepared before being bonded to the primary housing 10 by way of welding or riveting.
For example, in the implementations shown in FIGS. 9 and 10, identification element 13 is made from organic polymer plastic and then incorporated into the primary housing 10 by ultrasonic welding; in particular, in the implementations shown in FIGS. 9 and 10, identification element 13 is arranged with a convex beam 132 on the upper surface; and in the implementations, the convex beam 132 is ultrasonically welded (the ultrasonic welding process term, which is used to provide a guiding angle of the energy during ultrasonic welding). As well, in FIGS. 9 and 10, an ultrasonic overflow slot 115 around the portion 112 is provided on the portion 112 of the primary housing 10 for collection of excess glue generated by melting in the ultrasonic weld to prevent the solute spilling onto the surface of the primary housing 10 in the ultrasonic weld.
Still another example, FIG. 11 illustrates a schematic view of the identification element 13a being implemented by swaging on a portion 112a of the primary housing 10; in particular, the portion 112a of the primary housing 10 is provided with a card slot 115a; at least one snap 132a is provided on the inboard surface of the identification element 13a. In the assembly, the identification element 13a is stably bonded to the primary housing 10 by swiping the identification element 13a outside the portion 112a of the primary housing 10 and snapping the snap 132a into the card slot 115a. In the above implementations, the identification element 13/13a is rigid.
As shown in FIGS. 12-14, another example illustrates the identification element 13b directly molded around the primary housing 10 using a moldable material. The portion 112b of the primary housing 10 has an injection molding slot 115b circumferentially surrounding it. The identification element 13b is formed by curing a moldable material such as silicone or thermoplastic elastomer (TPE) injected into the injection molding slot 115b, for example, using a two-color injection molding process. In the implementation shown in FIGS. 12-14, a slot 116b is provided on portion 111b of the primary housing 10 adjacent to portion 112b. Slot 116b is used for positioning or sealing the mold within it to prevent the moldable material from overflowing the injection molding slot 115b. After preparation is complete and the mold is removed, slot 116b is exposed or opened.
Furthermore, as shown in FIG. 14, at least one side of the width of portion 112b of the primary housing 10 has an injection molding slot for two-color injection molding. During the injection process, a feed channel for injection is provided. After injection is complete, the material within the injection molding slot cures integrally with the identification element 13b to form an extension portion 133b. The extension portion 133b extends along the longitudinal direction of the primary housing 10 over portion 112b.
In this implementation, when portion 112b of the primary housing 10 of the atomizer 100 is housed or received within the receiving cavity 270 of the power source mechanism 200, the flexible identification element 13b molded by two-color injection molding abuts the open end of the receiving cavity 270. It also provides an airtight seal for the gap between the atomizer 100 and the receiving cavity 270. Alternatively, the flexible identification element 13b is also used to provide a seal between the primary housing 10 and the receiving cavity 270 of the power source mechanism 200.
In certain implementations, in addition to the basic polymer plastic or silicone material, the identification elements 13/13a/13b may also be doped with or include fluorescent or glow-in-the-dark materials. This is more advantageous for enhancing the color recognition of the identification elements 13/13a/13b.
It should be noted that the specification and accompanying drawings in the present application provide preferred examples of the present application, but are not limited to the examples described in this specification. Furthermore, those of ordinary skill in the art can make improvements or variations based on the above specification, and all such improvements and variations should fall within the scope of protection of the appended claims of the present application.
