[0037] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the electronic atomizing device further includes a power supply component connected to the atomizing assembly 30. The power supply component includes a bracket 80, a power supply structure 90, and an airflow sensor 100.

The receiving groove 84 and the mounting groove 83 are partitioned. The receiving groove 84 can be used for mounting the airflow sensor 100 and the second sealing structure 120. The second bottom wall 805 can be the groove bottom wall of the receiving groove 84 and the mounting groove 83.
[0043] In some embodiments, the bracket 80 is provided with a first vent hole 85 extending from the second end 80b to the first end 80a. Specifically, the first vent hole 85 can extend from the mounting groove 83 to the communication groove 82 and is located at one side of the accommodation cavity 81. The bracket 80 can be provided with an air inlet channel 102. Specifically, the first vent hole 85 and the communication groove 82 can form at least part of the air inlet channel 102. The air inlet channel 102 can be in communication with the outside and the suction air channel 101.
[0044] In some embodiments, the first vent hole 85 is provided with a partition plate 851 arranged transversely to the first vent hole 85, which can divide the first vent hole 85 into two spaces in the axial direction. The partition plate 851 is provided with a gas guide column 852 protruding towards the first end 80a.

By arranging the partition plate 851 and the gas guide column 852, the gas flow can be facilitated, and the leakage or condensate flow out of the shell 10 can be reduced.
[0045] In some embodiments, the bracket 80 is provided with a second vent hole 86. The second vent hole 86 and the first vent hole 85 are arranged at two opposite sides of the accommodation cavity 81, respectively. The second vent hole 86 can extend from the second end 80b to the first end 80a. Specifically, the second vent hole 86 can extend from the accommodation groove 84 to the communication groove 82 and is in communication with the communication groove 82 and the accommodation groove 84. The bracket 80 is provided with a sensing air channel 103. Specifically, the accommodation groove 84, the second vent hole 86, and the communication groove 82 are in communication to form at least part of the sensing air channel 103. The sensing air channel 103 can be in communication with the gas flow sensor 100 and the suction air channel 101.
[0046] In some embodiments, the first bottom wall 804 is provided with an air inlet 87, which can be in communication with the second air hole 86, and the second air hole 86 can be in communication with the communication groove 82 through the air inlet 87. The air inlet 87 can be a long and narrow strip-shaped hole, and the size of the cross section of the air inlet 87 is smaller than the size of the cross section of the second air hole 86. Specifically, the air inlet 87 has a long axis and a short axis in its cross section, and the cross section of the second air hole 86 has a width and a length, and the length direction of the second air hole 86 can be in the same direction as the long axis direction. The long axis size of the air inlet 87 is smaller than the length size of the second air hole 86, and the short axis size of the air inlet 87 is smaller than the width size of the second air hole 86. In other embodiments, the cross sections of the air inlet 87 and the second air hole 86 can also be circular, and the radial size of the air inlet 87 can be smaller than the radial size of the second air hole 86. By setting the small size of the air inlet 87, the aerosol can be blocked again to enter the second air hole 86, thereby blocking the aerosol from entering the airflow sensor 100, avoiding the corrosion of the aerosol or the condensed liquid of the aerosol to the airflow sensor 100, thereby ensuring the sensitivity and normal use of the airflow sensor 100, and because the cross section size of the second air hole 86 is large, the sensitivity of the airflow sensor 100 can be increased by facilitating the airflow, and the mold processing is also facilitated.
[0047] In some embodiments, the second bottom wall 805 is provided with an air inlet groove 88, which can extend to the hole wall of the second air hole 86, and the second air hole 86 and the airflow sensor 100, and when the user inhales, the airflow can be output from the airflow sensor 100 to the air inlet groove 88 and the second air hole 86. The airflow sensor 100 is provided with an airflow through hole 1001 facing the air inlet groove 88. The airflow through hole 1001 can be located on one side of the second air hole 86. The slot of the air inlet groove 88 is at least partially arranged towards the airflow through hole 1001.
[0048] In some embodiments, the first air hole 85 and the second air hole 86 can be independently sealed. In some embodiments, the first air hole 85 is provided with a first sealing structure 110 at the second end 80b, and the first sealing structure 110 is at least partially embedded in the mounting groove 83 and is in interference fit with the groove wall of the mounting groove 83. The first sealing structure 110 can be a first sealing silica gel. Of course, it can be understood that in other embodiments, the first sealing structure 110 can not be limited to the first sealing silica gel, but can be other sealing members. The first sealing structure 110 is provided with an air inlet through hole 1101, and the central axis of the air inlet through hole 1101 is arranged in parallel with the central axis of the first air hole 85. The air inlet through hole 1101 can be in communication with the first air hole 85 to form at least part of the air inlet channel 102. In some embodiments, the first sealing structure 110 can also be omitted.
[0049] In some embodiments, the second vent hole 86 is provided with a second sealing structure 120 at the second end 80b, which is at least partially embedded in the accommodation groove 84 and is in interference fit with the groove wall of the accommodation groove 84. The second sealing structure 120 can be sleeved on the outer periphery of the airflow sensor 100. The second sealing structure 120 is provided with a communication hole 121, which can communicate with the airflow passage 1001 and the air inlet groove 88. The communication hole 121 can be coaxially arranged with the airflow passage 1001. In some embodiments, the second sealing structure 120 can be a sealing sleeve, which can be a silica gel sleeve. Of course, it is understood that in other embodiments, the second sealing structure 120 can not be limited to a silica gel sleeve, which can be other elastic sealing sleeves. In some embodiments, the second sealing structure 120 is in contact with the second bottom wall 805, and the end of the second sealing structure 120 in contact with the second bottom wall 805 has an end wall 122, and the communication hole 121 is arranged on the end wall 122. The inner surface of the end wall 122 is spaced apart from the end surface of the airflow passage 1001 by a set distance, which is greater than or equal to 0.5 mm. By setting the set distance, it can be ensured that the airflow sensor 100 will not be squeezed by the second sealing structure 120 to cause false start.
[0050] In some embodiments, the suction air passage 101 can be formed at the central axis of the housing 10, one end of which extends to the suction port 71 of the suction nozzle 70, and the other end extends to the communication groove 82. The air inlet passage 102 extends from the second end 80b to the first end 80a, which can be sequentially communicated by the air inlet through hole 1001, the first vent hole 85, the communication groove 82. The sensing air passage 103 is integrally formed with the air inlet passage 102. Specifically, the sensing air passage 103 and the air inlet passage 102 are integrally formed with the bracket by injection molding, the sensing air passage 103 and the air inlet passage 102 are independently arranged, and at least part of the sensing air passage 103 and the air inlet passage 102 are blocked, which prolongs the distance between the sensing air passage 103 and the air inlet passage 102, avoids unstable airflow of the airflow sensor 100, ensures the sensitivity of the airflow sensor 100, and reduces the start-up delay or failure of the airflow sensor 100. Specifically, the sensing air passage 103 and the air inlet passage 102 are arranged on two opposite sides of the accommodation cavity 81 and are both arranged to be blocked from the accommodation cavity 81, thereby achieving at least partial blocking between them. The sensing air passage 103 can extend from the second end 80b to the first end 80a, which can be sequentially communicated by the airflow passage 1001, the communication hole 121, the air inlet groove 88, the second vent hole 86, the air inlet 87, and the communication groove 82. Since the communication end of the air inlet groove 88 and the second vent hole 86 is arranged in a staggered manner with the airflow passage 1001, the sensing air passage 103 is partially bent, which can also reduce the entry of aerosol into the airflow sensor 100, avoid corrosion of the airflow sensor 100, ensure the service life of the airflow sensor 100, and reduce the risk of start-up delay of the airflow sensor 100.
[0051] The inductive air passage 103 can be blocked by the blocking structure 53 from aerosol in the suction air passage 101. The blocking structure 53 can be disposed between the air inlet 87 and the through hole 521. The blocking structure 53 is spaced apart by two blocking walls, and the space between the two blocking walls can meet the requirement of allowing the air flow of the air inlet 87 to pass through but not allowing the aerosol to pass through in some embodiments.
[0052] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
