[0049] The electronic atomization device is used for heating an atomization substrate to generate atomized gas. In the prior art, the conventional air inlet structure of the electronic atomization device is that the internal structure of the shell is designed to form a closed air inlet channel, and when a user inhales, external airflow is introduced to the atomization core assembly through the air inlet channel, and the external airflow flows through the atomization core assembly and carries the atomized airflow to the mouthpiece of the device. At present, the shapes of the electronic atomization devices on the market are not unique, and different structures of the air inlet channel need to be designed according to different shell structures, which increases the design difficulty; and the air inlet amount of the air inlet channel is difficult to improve due to the need to accommodate the power assembly inside the shell, which affects the atomization efficiency due to insufficient air inlet amount.

[0050] Therefore, in order to solve the above problems, the present application designs a support, which directly forms an air channel on the support part of the support, one end of the air channel is used for being in communication with the atomization assembly, the other end of the air channel is used for being in communication with the outside of the shell, and then the air channel can form an air inlet channel for air inlet; the air channel is independent of the shell design, and the structural interference between the air channel and the shell is small, which reduces the design difficulty of the air channel. Moreover, the support part includes at least two independent air channels, and the multiple air channels can be used for air inlet at the same time, which is beneficial to increase the air inlet amount and thus improve the atomization efficiency; and the air inlet amount is improved while the occupied space is small.

Moreover, the support portion 7 comprises at least two air passages 9 which are independent of each other, the multiple air passages 9 can be used for air inlet at the same time, which is beneficial to increasing the air inlet amount and thus improving the atomization efficiency; and the multiple air passages 9 are located at the outer periphery of the containing space 8, which improves the air inlet amount while occupying a small space.

[0056] It can be understood that, in order to improve the capacity of a single air passage 9, the thickness of the support portion 7 can be increased, or a protruding structure can be arranged at a local position of the support portion 7. The support portion 7 can comprise one or more of a plate body, a beam body, a column body and the like support structures, so as to stably connect the first base 5 and the second base 6. Moreover, the support portion 7 can be an integrated support structure; alternatively, the support portion 7 can be composed of multiple support structures arranged separately.

[0057] Reference Figure 1 , Figure 2 , Figure 3 In some embodiments, the bracket 1 is an axisymmetric structural member, and the at least two air passages 9 are arranged symmetrically about the axis of symmetry of the bracket 1.

[0058] Specifically, the bracket 1 is designed as an axisymmetric structural member, which has good stability and a simple structure and is easy to manufacture. The two air passages 9 are arranged symmetrically on the bracket 1, that is, the two air passages 9 are arranged on opposite sides of the bracket 1, so as to reduce the occupation of the air passage 9 structure to the containing space 8.

[0059] For example, reference Figure 2The projection shape of the support 1 is rectangular, and the air passages 9 can be arranged on both sides of the support 1 in the length direction, or arranged on both sides of the support 1 in the width direction. Alternatively, the projection shape of the support 1 is circular, that is, the air passages 9 can be arranged on any two opposite sides of the support 1.

[0062] It can be understood that the thickness of the connecting plate 701 has limitations, and it is difficult to arrange the air passages 9 on the connecting plate 701; therefore, the support column 702 protruding from the connecting plate 701 is arranged on the connecting plate 701, and the air passages 9 are arranged through the support column 702, which is conducive to the manufacture of the air passages 9 and improves the capacity of the air passages 9. In addition to being able to form air passages 9, the support column 702 can also improve the stability of the connecting structure between the first base 5 and the second base 6, and the structure design is ingenious.

[0063] The support part 7 can have only one connecting plate 701 arranged around the first base 5 and the second base 6. The support part 7 can also include a plurality of connecting plates 701 arranged at intervals.

[0065] It can be understood that the two connecting plates 701 are arranged on both sides of the support 1 along the width direction, and the support column 702 is arranged in the middle part of the connecting plate 701; then the air passages 9 formed on the support column 702 are close to the center position of the support 1. The support 1 of the present application is particularly applied to the electronic atomization device 1000, and the air passages 9 are close to the center position of the support 1, which is conducive to achieving the center air inlet effect, shortening the flow path of the airflow, and accelerating the air inlet rate, which helps the atomization assembly 2 to better atomize the aerosol substrate and improve the taste of the atomized gas.

[0066] With reference to Figure 1 , Figure 2 ,Figure 3 In some embodiments, the support 702 is arranged on the side wall of the connecting plate 701 facing the accommodation space 8.

[0067] It can be understood that the support 702 protrudes towards the accommodation space 8, and the side wall structure of the connecting plate 701 away from the accommodation space 8 is flat; refer to Figure 6 , and then the bracket 1 can be more smoothly installed in the shell 4, reducing structural interference; the outer side wall of the connecting plate 701 can be fitted with the inner wall of the shell 4, making the structure compact.

[0068] Refer to Figure 1 In some embodiments, the first base 5 includes first edges 501 opposite in the width direction and a second edge 502 connected to the two first edges 501; the second base 6 includes third edges 601 opposite in the width direction and a fourth edge 602 connected to the two third edges; and the connecting plate 701 is connected to the first edge 501 and the fourth edge 602 on the same side.

[0069] Specifically, the connecting plate 701 is connected to the first edge 501 and the fourth edge 602, which is conducive to increasing the size of the accommodation space 8 to meet the requirement of arranging the battery cell 301 of the power assembly 3 in the accommodation space 8; and the connecting plate 701 extends along the length direction of the bracket 1, which can improve the better structural support.

[0072] Refer to Figure 1 , Figure 4 , Figure 5 The bracket 1 has openings on both sides in the length direction, which are in communication with the accommodation space 8, so that the battery cell 301 can be arranged in the accommodation space 8. And the shape of the accommodation space 8 tends to be a cuboid, which is suitable for the shape of the battery cell 301, that is, the space utilization rate of the accommodation space 8 is high, which is conducive to increasing the size of the battery cell 301 and improving the atomization power of the electronic atomization device 1000.

The cover plate 11 is provided with a gas hole structure 15 for communication between the air inlet 901 and the air inlet groove 14.

[0074] Specifically, the user controls the air adjustment switch 12 to slide in the horizontal groove 13 to drive the cover plate 11 to move relative to the second base 6. When the cover plate 11 is adjusted to stagger the gas hole structure 15 and the air inlet 901 in the vertical direction, the cover plate 11 can isolate the air inlet 901 from the air inlet groove 14, thereby organizing the air intake. When the cover plate 11 is adjusted to align the gas hole structure 15 and the air inlet 901 in the vertical direction, external airflow can flow through the air inlet groove 14, the gas hole structure 15, and into the air inlet 901, allowing the electronic atomization device 1000 to smoothly intake air.

[0075] In some embodiments, the air inlet groove 14 is a strip-shaped groove, and the gas hole structure 15 can include a plurality of gas holes with different diameters arranged in sequence along the length direction of the air inlet groove 14. By adjusting the cover plate 11 to be in different positions, different diameters of gas holes are communicated with the air inlet groove 14 and the air inlet 901, or different numbers of gas holes are communicated with the air inlet groove 14 and the air inlet 901. One-key adjustment of the air intake of the electronic atomization device 1000 is achieved. Under different air intake amounts, the atomization assembly 2 atomizes the aerosol substrate to different degrees, and different tastes of atomized gas can be formed.

[0076] In some embodiments, the electronic atomization device 1000 further comprises a sealing gasket 16 arranged between the air inlet 901 and the cover plate 11, and the second base 6 is formed with a limiting groove 17 limiting the sealing gasket 16.
