BACKGROUND

[0004] Traditional tobacco products (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. The art has developed products that release compounds by heating, but not burning, to replace these traditional tobacco products. An example of such a product is an electronic atomization device, which generally comprises an atomizable liquid substrate and an atomization assembly including a liquid guide and a heating element, the liquid guide conducts the liquid substrate to the heating element, and the heating element heats the liquid substrate to atomize it to produce an inhalable vapor or aerosol, which can contain nicotine and / or flavorants and / or aerosol generating substances (e.g., glycerol).

[0005] In order to obtain a better smoking taste and maximize the taste of the liquid substrate, the liquid guide of the above-mentioned atomization assembly is usually made of a fibrous material. Since the fibrous material has good liquid guiding ability, the smoking taste of the aerosol generated by the heating element will be better.

[0006] However, due to the good liquid guiding ability of the liquid guide made of fibrous material, the liquid substrate is prone to leak from the liquid guide and overflow the atomizer during the conduction of the liquid substrate, thereby affecting the user's experience.

[0044] Please continue to refer to FIG. 2, a bracket 30 is arranged in the main housing 10, the bracket 30 is fixedly connected with the base 20, the bracket 30 defines a holding chamber 31, a longitudinally extending tubular body 40 is arranged in the holding chamber 31, and an atomizing assembly 50 is arranged in the tubular body 40. The bracket 30 is provided with a plurality of liquid guide grooves 31 which communicate with the liquid storage cavity 13 and extend along the longitudinal direction of the bracket 30, and the tubular wall of the tubular body 40 is provided with a liquid guide hole (not shown in the figure), so that the liquid substrate in the liquid storage cavity 13 can flow to the atomizing assembly 50 through the liquid guide grooves 31 and the liquid guide hole, and the atomizing assembly 50 can then atomize the liquid substrate to generate an aerosol.

[0045] As shown in FIG. 3, the atomizing assembly 50 comprises a first liquid guide element 51 and a heating element 52 combined on the first liquid guide element 51, the first liquid guide element 51 is formed with a through hole 511 extending longitudinally through the first liquid guide element 51, so that the first liquid guide element 51 has an outer surface 512 and an inner surface 513, and the heating element 52 is combined on the inner surface 513. The liquid substrate flows to the outer surface 512 of the first liquid guide element 51 through the liquid guide grooves 31 and the liquid guide hole, the first liquid guide element 51 then absorbs the liquid substrate and delivers the liquid substrate to the heating element 52 on the inner surface 513, the heating element 52 can then heat and atomize the liquid substrate to generate an aerosol, and release the aerosol in the through hole 511, that is, the through hole 511 is the atomizing chamber of the atomizer 100.

[0046] In order to reduce the probability of liquid substrate leaking on the first liquid guide element 51, the atomizer 100 further comprises a second liquid guide element 60 surrounding the first liquid guide element 51, the first liquid guide element 51 and the second liquid guide element 60 are in contact, the liquid guide groove 31 is in communication with the liquid storage cavity 13 and the second liquid guide element 60, the liquid substrate in the liquid storage cavity 13 flows to the second liquid guide element 60 through the liquid guide groove 31 first, the second liquid guide element 60 absorbs the liquid substrate and then transmits it to the first liquid guide element 51, and then the first liquid guide element 51 transmits it to the heating element 52, as shown in the liquid substrate flow path R1 shown in FIG. 2.

[0047] The first liquid guide element 51 and the second liquid guide element 60 are made of capillary core material, such as any one of cotton fiber, non-woven fabric, glass fiber rope, etc., or a porous ceramic body with a microporous structure, and after absorbing the liquid substrate, the first liquid guide element 51 and the second liquid guide element 60 can transmit the liquid substrate through the internal voids or microporous structure. The heating element 52 can be preferably configured in a mesh shape to improve heating efficiency, and can be adapted to the shape of the through hole 511 to be combined on the inner surface 513 of the first liquid guide element 51. For example, as shown in some examples in FIG. 3, the first liquid guide element 51 is stacked by multiple layers of fiber sheet and wound around the periphery of the heating element 52.

[0048] As shown in FIG. 2, the main housing 10 further comprises an air guide pipe 14 extending in the liquid storage cavity 13, one end of the air guide pipe 14 is in communication with the air outlet 111, and the other end extends into the tubular body 40, so that the aerosol released in the through hole 511 can enter the air guide pipe 14 along the tubular body 40, and further transmitted to the air outlet 111 by the air guide pipe 14. At the same time, the base 20 is provided with an air inlet 24 for external air to enter the atomizer 100, when the user sucks on the air outlet 111, a negative pressure is generated inside the atomizer 100, which promotes the external air to enter the atomizer 100 through the air inlet 24, and then enters the atomization chamber (through hole 511) along the internal air inlet channel, and then flows into the air guide pipe 14, and finally transmitted to the air outlet 111 by the air guide pipe 14, so that the user can smoke the aerosol by sucking on the air outlet 111, as shown in the aerosol transmission path R2 in FIG. 2.

[0049] Please continue to refer to FIG. 2, the base 20 is provided with an electrode hole, the electrode hole is provided with a conductive electrode 21, the conductive electrode 21 is used for electrically connecting an external power supply assembly and the heating element 52, the conductive electrode 21 transmits the electric energy of the external power supply assembly to the heating element 52, and the heating element 52 can heat and atomize the liquid substrate.

[0050] As shown in FIG. 2, FIG. 4 and FIG. 5, the bracket 30 comprises a first portion 32 and a second portion 33 distributed along the longitudinal direction, the outer diameter of the first portion 32 is larger than that of the second portion 33, wherein the first portion 32 is close to the liquid storage cavity 13, and the second portion 33 is away from the liquid storage cavity 13, that is, the first portion 32 is above the second portion 33, and the liquid guide groove 31 is arranged on the first portion 32. The base 20 comprises a bottom wall 22 and a side wall 23 extending from the bottom wall 22 towards the liquid storage cavity 13, the side wall 23 is fixedly connected with the first portion 32, so that the accommodation chamber 331 is defined between the side wall 23 and the second portion 33.

[0051] Specifically, as shown in FIG. 4 and FIG. 5, the first portion 32 of the bracket 30 is provided with a buckle 323, and the side wall 23 of the base 20 is provided with a clamping groove 231 matched with the buckle 323, the buckle 323 is clamped and connected with the clamping groove 231, so that the base 20 and the bracket 30 are fixedly connected. It is easy to understand that in some embodiments, the clamping groove can also be arranged on the first portion 32, and the corresponding buckle is arranged on the side wall 23 to realize the fixed connection of the base 20 and the bracket 30.

[0052] Further, the first portion 32 is also provided with an air passage for guiding external air into the liquid storage cavity 13 to supplement air in the liquid storage cavity 13. When the atomizer 100 works, as the liquid matrix in the liquid storage cavity 13 is consumed, the volume of the liquid storage cavity 13 becomes larger, which causes the air pressure in the liquid storage cavity 13 to decrease and generate negative pressure. Under the action of the negative pressure, the liquid matrix in the liquid storage cavity 13 cannot flow smoothly to the atomization assembly 50, which is easy to cause the atomization assembly 50 to dry out due to insufficient liquid supply. By arranging the air passage, air can be supplemented into the liquid storage cavity 13, so as to maintain the air pressure balance in the liquid storage cavity 13, and enable the liquid matrix to continue to flow smoothly to the atomization assembly 50.

[0053] The accommodation chamber 331 and the air passage are communicated, and since the side wall 23 of the base 20 and the first portion 32 of the bracket 30 are connected, the accommodation chamber 331 defined between the side wall 23 and the second portion 32 has a larger storage space, so that the accommodation chamber 331 can collect more liquid matrix leaked from the liquid storage cavity 13 through the air passage.

[0054] In this embodiment, by arranging the atomization assembly 50 in the bracket 30, the contact area of the atomization assembly 50 directly contacting with the liquid matrix can be reduced, and at the same time, the accommodation chamber 331 with a larger space is formed by the side wall 23 of the base 20 and the second portion 32 to collect the liquid matrix leaked from the air passage, so as to reduce the probability of liquid matrix leakage as a whole.

[0055] Further, at least a portion of the second liquid guide element 60 is located in the second portion 32, and since the second portion 32 has a smaller outer diameter, at least a portion of the second portion 32 can be properly compressed between the inner wall of the second portion 32 and the atomization assembly 50, which is advantageous for controlling the penetration speed of the liquid substrate and reducing the leakage of the liquid substrate.

[0056] In some embodiments, as shown in FIG. 6, the inner wall of the liquid guide groove 31 includes a first section 311 extending longitudinally and a second section 312 extending obliquely from the first section 311, and the liquid substrate in the liquid storage cavity 13 flows to the second liquid guide element 60 through the first section 311 and the second section 312 in turn. By providing the oblique second section 312, when the remaining liquid substrate in the liquid storage cavity 13 is less, the remaining liquid substrate can be all guided to the second liquid guide element 60, and then delivered to the atomization assembly 50 for atomization by the second liquid guide element 60, thereby improving the utilization rate of the liquid substrate.

[0057] In some embodiments, as shown in FIGS. 2 and 6, the atomizer 100 further includes a first sealing member 70 sealing the liquid storage cavity 13, and the first sealing member 70 is provided with an annular groove 71 in which the tubular body 40 is partially inserted. The first sealing member 70 is provided with a liquid guide hole (not shown) through which the liquid substrate flows into the liquid guide groove 31. The first sealing member 70 is sleeved on the first portion 32 of the support 30, and the first sealing member 70 is in elastic abutment with the inner wall of the main housing 10 to seal the liquid storage cavity 13, so that the liquid substrate flows along the preset path and avoids leaking through the assembly gap between the support 30 and the inner wall of the main housing 10.

[0058] The first portion 32 includes an extension 321 extending towards the liquid storage cavity 13, and the extension 321 extends into the liquid storage cavity 13 through the first sealing member 70, and the extension 321 and the first sealing member 70 define the air passage described above to guide external air into the liquid storage cavity 13.

[0059] Specifically, as shown in FIGS. 6 and 8, the outer surface of the extension 321 is formed with a first groove 3211 extending longitudinally, and when the extension 321 passes through the first sealing member 70, the first sealing member 70 and the first groove 3211 define the air passage described above. It is easy to understand that in some embodiments, the first groove 3211 can also be provided on the first sealing member 70, and then the surface of the extension 321 and the first groove 3211 define the air passage described above.

[0060] In some embodiments, as shown in FIG. 2, the atomizer 100 further comprises a second seal 80 sealing the receiving chamber 331, and the atomizing assembly 50 is supported on the second seal 80, and the second seal 80 is in elastic abutment with the inner wall of the main housing 10, thereby sealing the receiving chamber 331. The first seal 70 and the second seal 80 can be any one of silica gel, rubber, latex, etc., and can achieve sealing by being in elastic abutment with the inner wall of the main housing 10.

[0061] Further in some embodiments, as shown in FIG. 2 and FIG. 7, the second seal 80 has a second groove 81 thereon, and the local interference of the second portion 33 is inserted in the second groove 81, so as to provide support for the bracket 30, and make the bracket 30 more stably fixed in the main housing 10.

[0062] In addition, in some embodiments, as shown in FIG. 2 and FIG. 7, the outer surface of the second seal 80 is formed with a third groove 82 extending longitudinally, and the third groove 82 is defined with the side wall 23 of the base 20 to form an airflow channel, which can be regarded as part of the above-mentioned air channel, and the airflow channel is in communication with the receiving chamber 331, so as to guide external air into the receiving chamber 331, and since the receiving chamber 331 is in communication with the above-mentioned air channel, the external air can further flow into the liquid storage cavity 13 through the receiving chamber 331 and the above-mentioned air channel, so as to supplement the air in the liquid storage cavity 13.

[0063] In some embodiments, as shown in FIG. 2 and FIG. 4, the side surface of the first portion 32 is formed with a flange 322, and when the first seal 70 is sleeved on the first portion 32, the flange 322 provides support for the first seal 70, thereby improving the sealing effect of the first seal 70.

In the preferred embodiment shown in FIG. 9, the seal 260 is configured to extend along the cross-sectional direction of the power supply assembly 200 and is preferably made of a flexible material such as silicone, thereby preventing the liquid substrate flowing from the atomizer 100 to the receiving cavity 270 from flowing to the controller 220, the sensor 250, etc. within the power supply assembly 200.
