[0040] Existing products have the problem that it is difficult to strike a balance between sealing performance and air intake performance at the upstream of the airflow in the atomization channel. In order to solve the problem that it is difficult to strike a balance between sealing performance and air intake performance, the present application discloses the following technical solution, which improves the sealing performance of the atomization device 10 by setting a sealing structure 100 and ensures that the atomization channel can smoothly intake air.

[0041] See also Figures 1 to 3 The disclosed atomization device 10 is used to heat the atomization matrix into an aerosol, and includes a sealing structure 100, which is located at the upstream end of the atomization channel 200, and the sealing structure 100 includes a sealing pad 110 and an air inlet pad 120, wherein the sealing pad 110 and the air inlet pad 120 are stacked and arranged according to the air inlet direction; the sealing pad 110 includes a sealing hole 111 that is sealed with the atomization channel 200; the air inlet pad 120 includes an air inlet hole 121 and an air guide groove 122, and the air inlet hole 121 connects the air guide groove 122 and the sealing hole 111; the air guide groove 122 extends from the circumference of the air inlet pad 120 to the air inlet hole 121.

[0042] In the atomizing device 10 provided by the present application, the sealing hole 111 is sealed with the outer periphery of the atomizing channel 200, thereby ensuring the sealing performance; in addition, the air intake hole 121 and the air guide groove 122 are provided on the air intake pad 120, and the air intake hole 121 is connected to the air guide groove 122 and the sealing hole 111, and air can enter the air intake hole 121 from the peripheral surface of the air intake pad 120 through the air guide groove 122, and enter the atomizing channel 200 through the sealing hole 111, thereby ensuring the air intake performance. It can be seen that the atomizing device 10 of the present application can take into account both the sealing performance and the air intake performance.

[0043] It can be understood that the atomization device 10 is divided into upstream and downstream according to the air entry direction, and the upstream and downstream correspond to the axial direction Z of the atomization device 10, wherein the axial direction Z of the atomization device 10, the length direction X of the atomization device 10 and the width direction Y of the atomization device 10 are perpendicular to each other.

[0044] See also Figures 4 to 7 In some embodiments, the atomizing device 10 includes a liquid storage element 300 for holding an atomizing matrix; in some embodiments, the atomizing device 10 includes an atomizing element 400 for heating and atomizing the atomizing matrix to form an aerosol. The specific structure of the liquid storage element 300 and the atomizing element 400 is not described in detail here for the time being, and will be described later. It should be noted that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the atomizing device 10. In other embodiments of the present application, the atomizing device 10 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently.

[0045] The function of the air intake pad 120 is to introduce air into the sealing hole 111 to provide air for the atomization channel 200. The number of the air guide grooves 122 on the air intake pad 120 shown in the figure can be one or more. In some embodiments of the present application, in order to improve the air intake performance of the above-mentioned sealing structure 100, the number of the air guide grooves 122 is multiple, and the multiple air guide grooves 122 are connected to the air intake hole 121 around, so that the air around can enter the air intake hole 121 from multiple directions. In the figure, the number of the air guide grooves 122 is four, and the four air guide grooves 122 are arranged in a cross shape. The cross-shaped arrangement can allow air to enter the air intake hole 121 from four directions.

[0046] The above-mentioned sealing structure 100 is adapted to the cross-section of the liquid storage element 300. In the figure, the cross-section of the liquid storage element 300 is generally rectangular, and the cross-section of the sealing structure 100 is generally rectangular; or, in some embodiments, the cross-section of the liquid storage element 300 is generally circular, and the cross-section of the sealing structure 100 is generally circular.

[0047] On the premise that the cross-section of the liquid storage element 300 is substantially rectangular, there are four air guide grooves 122 arranged in a cross shape in the sealing structure 100, some of which are longer and some of which are shorter. In some examples of the present application, the air guide grooves 122 with longer lengths can be configured as the main air guide grooves for the main air intake, and the air guide grooves 122 with shorter lengths can be configured as the auxiliary air guide grooves for the auxiliary air intake.

[0048] The main function of the air inlet hole 121 is to enable the air guide groove 122 to intake air into the atomizing element 400; in addition, in some embodiments where a heating element 420 is provided, the heating element 420 needs to pass through the sealing structure 100 to be connected to the battery 700. To this end, in order to facilitate the connection between the heating element pin 421 of the heating element 420 and the battery 700, the heating element pin 421 can be connected to the battery 700 through the air inlet hole 121, which is not elaborated here.

[0049] In addition, the shape of the air inlet 121 is a circular hole or other shapes. In some examples of the present application, the air inlet 121 is a special-shaped hole to facilitate the installation of the heating element pin 421. Specifically, the air inlet 121 is a circular hole 1211 as a whole, and at least one notch 1212 is provided on the basis of the circular hole 1211, and the notch 1212 can accommodate the passage of the heating element pin 421 to improve assembly efficiency.

[0050] Since a battery 700 and the like are disposed upstream of the sealing structure 100, the air intake cushion 120 includes a plurality of support portions 123, and the outer contours of the plurality of support portions 123 form the outer contour of the air intake cushion 120; and air guide grooves 122 are formed between adjacent support portions 123. Since the outer contours of the plurality of support portions 123 form the outer contour of the air intake cushion 120, the effective support area of ​​the entire sealing structure 100 can be increased, thereby improving the support stability.

[0051] The above mainly introduces the structure of the air intake pad 120, and the following focuses on the structure of the sealing pad 110:

[0052] The main function of the sealing gasket 110 is to seal the upstream end of the atomization channel 200. The sealing gasket 110 can also support the liquid storage element 300 in combination with the air inlet pad 120. The setting position of the sealing hole 111 of the sealing gasket 110 can be adjusted as needed, for example, the sealing hole 111 is located at the center of the sealing gasket 110, or the sealing hole 111 is offset from the center of the sealing gasket 110.

[0053] The end surface of the sealing gasket 110 away from the air inlet cushion 120 is a plane or a curved surface, as long as the shape of the end surface of the sealing gasket 110 away from the air inlet cushion 120 matches the end surface of the downstream end of the liquid storage element 300. In the figure, the end surface of the downstream end of the liquid storage element 300 is a plane, and the end surface of the sealing gasket 110 that matches it is a plane.

[0054] The sealing hole 111 mainly seals with the atomizing channel 200 , specifically with the outer wall of the atomizing channel 200 , to reduce leakage of the atomized substrate from the gap between the outer wall of the atomizing channel 200 and the sealing hole 111 .

[0055] It should be noted that the atomization channel 200 is mainly formed in the liquid storage element 300, and the liquid storage element 300 is used to hold the atomization substrate. In some embodiments, it includes an oil cup 310 and a liquid storage cotton 320, and the liquid storage cotton 320 is filled inside the oil cup 310 to store the atomization substrate, and the atomization channel 200 forms the middle part of the liquid storage cotton 320.

[0056] In order to further improve the atomization effect, in some embodiments, the sealing gasket 110 further includes a sealing ring, and the sealing ring 112 is sealed with the oil cup 310 .

[0057] The function of the sealing ring 112 is mainly to seal with the oil cup 310 of the liquid storage element 300. For example, the sealing ring 112 can be fixed with the liquid storage element 300 in an interference fit manner. In one embodiment, the outer wall of the sealing ring 112 cooperates with the inner wall of the oil cup 310 of the liquid storage element 300; or in one embodiment, the inner wall of the sealing ring 112 cooperates with the outer wall of the oil cup 310 of the liquid storage element 300. However, no matter what kind of sealing cooperation is used, it is mainly to utilize the sealing ring 112 to produce a certain deformation due to the compression of the external force, and restore the original state after the external force is withdrawn. It should be noted that the number of the above-mentioned sealing rings 112 can be one or more, and multiple sealing rings 112 can form a multi-level seal between the sealing gasket 110 and the liquid storage element 300 to improve the sealing performance.

[0058] The sealing pad 110 and the air intake pad 120 can be a split structure or an integrated structure. In the split structure, the sealing pad 110 and the air intake pad 120 can be connected by an adhesive or welding; or in the split structure, the two are not connected, and the sealing between the two is achieved through their own elastic deformation. In the case where the sealing pad 110 and the air intake pad 120 are an integrated structure, the sealing performance between the two can be effectively guaranteed. Furthermore, the sealing pad 110 and the air intake pad 120 are integrally formed and can be made of an elastic material, for example, silicone.

[0059] The function of the atomizing element 400 is to heat and atomize the atomizing substrate to form an aerosol. As shown in the figure, the atomizing element 400 includes a heating element bracket 410 and a heating element 420, wherein the heating element bracket 410 is mainly arranged at the sealing hole 111 as a part of the atomizing channel 200, and one end of the heating element 420 is fixed to the inner wall of the sealing hole 111 of the sealing structure 100, and the heating element 420 is arranged inside the heating element bracket 410 to atomize the atomizing substrate.

[0060] In some embodiments, the liquid storage element 300 further includes a liquid guiding cotton 500, the liquid guiding cotton 500 includes a main liquid guiding portion 510 and an extension portion 520 extending radially from the main liquid guiding portion 510, the main liquid guiding portion 510 is located inside the atomizing element 400, and the extension portion 520 is exposed from the atomizing element 400. It can be seen that the liquid guiding cotton 500 of the present application is configured as a special shape, which can effectively improve the liquid guiding efficiency of the liquid guiding cotton 500, and effectively solve the problem of carbon deposition on the atomizing element 400 caused by insufficient liquid guiding of the liquid guiding cotton 500.

[0061] In addition, the heating element bracket 410 is provided with an opening 411 and an oil inlet 412 , wherein the opening 411 is provided to cooperate with the extension portion 520 of the liquid-conducting cotton 500 extending out of the atomizing element 400 ; the provision of the oil inlet 412 can improve the liquid-conducting efficiency of the liquid-conducting cotton 500 .

[0062] See also Figures 8 to 10In some examples, the atomizing device 10 may further include a housing 10a and a suction nozzle 10b, wherein the suction nozzle 10b is located at the downstream end of the housing 10a.

[0063] The above sealing structure 100 , the liquid storage element 300 and the atomizing element 400 are all disposed in the housing 10 a . In addition, the atomizing device 10 may further include an upper sealing structure 600 disposed between the nozzle 10 b and the liquid storage element 300 .

[0064] The absorbent cotton 800, the battery 700 and the circuit board 900 are arranged in sequence from near to far from the sealing structure 100, wherein the absorbent cotton 800 is located between the air inlet 121 of the sealing structure 100 and the battery 700. Even if leakage occurs from the air inlet 121, the absorbent cotton 800 can absorb it, thereby improving the reliability of the atomization device 10.

[0065] See also Fig.11 , the figure discloses an atomizing device, which includes the above-mentioned atomizing device 10 and a power supply device 20. The power supply device 20 is used to provide electrical energy to the atomizing device 10, and the atomizing device 10 is used to heat the atomizing matrix into an aerosol. The atomizing device can be a disposable product or a cartridge-changing product. For a disposable atomizing device, the atomizing device 10 and the power supply device 20 are fixedly connected; for a cartridge-changing atomizing device, the atomizing device 10 and the power supply device 20 are detachably connected, and the atomizing device 10 and the power supply device 20 can be replaced according to the usage.

[0066] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
