[0042] The power supply assembly and the electronic atomization device provided by the present application will be described in detail below in combination with embodiments.

[0043] Please refer to Figure 1 and Figure 2 , Figure 1 is an explosion schematic diagram of the first embodiment of the power supply assembly of the present application; Figure 2 is a structural schematic diagram of the first embodiment of the power supply assembly of the present application.

[0044] The electronic atomization device can be used for atomization of liquid to be atomized. The electronic atomization device comprises an atomization assembly (not shown in the figure) and a power supply assembly 10 connected to each other, the atomization assembly is used to store liquid to be atomized and atomize the liquid to form aerosol for users to smoke, the liquid can be liquid containing fragrance or odor, medicinal liquid and the like liquid to be atomized; the power supply assembly 10 is used to supply power to the atomization assembly, so that the atomization assembly can atomize the liquid to be atomized to form aerosol. The atomization assembly and the power supply assembly 10 can be integrally arranged, or can be detachably connected, and are designed according to specific needs.

[0045] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 is Figure 2 the partial cross-sectional schematic diagram of A-A shown in

[0046] Figure 4 is the first partial schematic diagram of the first embodiment of the power supply assembly of the present application; Figure 5 is Figure 4 the partial cross-sectional schematic diagram of B-B shown in

[0047] Specifically, in combination with Figure 1The power supply assembly 10 comprises a housing 1 and a bracket 2. The housing 1 is formed with a receiving portion 11 for receiving at least part of the atomization assembly. The bracket 2 is arranged in the receiving portion 11 and is used to connect the atomization assembly. The bracket 2 is provided with a starting air channel 22. The bracket 2 is used to connect an end of the atomization assembly and the housing 1 to form an air passage 41. The air passage 41 is in communication with the external air and the starting air channel 22, so that the external air enters the starting air channel 22 through the air passage 41. The direction of the external air flow is indicated by the arrow in the figure. Figure 3 In this way, the condensed liquid or the leaked liquid in the atomization assembly is less likely to enter the starting air channel 22 and the control board 3, thereby avoiding damage to the microphone and the control board 3, and improving the service life of the power supply assembly 10.

[0048] In an embodiment, in order to realize the connection between the starting air channel 22 and the air passage 41, an opening 25 is arranged on the side wall of the end of the starting air channel 22 close to the atomization assembly. Thus, the starting air channel 22 is in communication with the air passage 41 through the opening 25, so that the external air enters the starting air channel 22 through the air inlet hole 12, the air passage 41 and the opening 25 in sequence.

[0049] In order to further reduce the condensed liquid or the leaked liquid in the atomization assembly from directly entering the starting air channel 22, the end surface of the bracket 2 for connecting the atomization assembly is provided with a blocking portion 42. The blocking portion 42 is used to prevent the starting air channel 22 from being directly exposed to the atomization assembly, so as to reduce the direct entry of the liquid to be atomized along the vertical direction, i.e. the length direction of the power supply assembly 10, into the starting air channel 22, thereby damaging the microphone and the control board 3.

[0050] Further, in combination with Figure 3 and Figure 5 , the port 23 of the end of the starting air channel 22 close to the atomization assembly is located on the end surface of the bracket 2 for connecting the atomization assembly. The blocking portion 42 blocks the port 23 to realize the sealed blocking. The blocking portion 42 can be a plastic blocking portion, which can be made of plastic.

[0051] In an embodiment, in combination with Figures 1 to 5The side wall of the shell 1 is provided with air inlet holes 12, which can be one or more. The ambient air can be introduced into the air passage 41 through the air inlet hole 12, so that the ambient air enters the starting air passage 22 through the air inlet hole 12 and the air passage 41. In this embodiment, the number of air inlet holes 12 is two, which are symmetrically arranged on the two side walls of the shell 1 along the width direction of the power assembly 10, and correspond to the opposite ends of the air passage 41. It can be understood that the number of air inlet holes 12 can be three, four, five, etc. As long as the air inlet hole 12 is formed on the side wall of the shell 1, the air inlet hole 12 can be symmetrically arranged on the shell 1 or not symmetrically arranged, which is not limited here. In addition, the shape of the air inlet hole 12 can be any shape, such as a circle or a square, which is not limited here.

[0052] Please refer to Figure 6 , Figure 6 is a second partial view of the first embodiment of the power assembly of the present application. In combination with Figures 1 to 5 The bracket 2 is used to connect the air passage 41 between one end of the atomization assembly and the shell 1. The air passage 41 can be formed in at least two ways. Specifically, the first way to form the air passage 41: the bracket 2 is used to connect the outer side of one end of the atomization assembly to form a ventilation groove 21, which forms the air passage 41 between the inner surface of the shell 1. The ventilation groove 21 extends along the circumference of the outer side of the bracket 2 used to connect one end of the atomization assembly. In this embodiment, two air inlet holes 12 are symmetrically arranged on the side wall of the shell 1, and the ventilation groove 21 is recessed on the outer side of the bracket 2 used to connect one end of the atomization assembly. The two air inlet holes 12 are respectively located at the symmetrically opposite ends of the ventilation groove 21 and are in communication with the ventilation groove 21.

[0053] The second way to form the air passage 41: the inner surface of the shell 1 is at least partially recessed to form a ventilation groove 21, which forms the air passage 41 between the outer side of the bracket 2 used to connect one end of the atomization assembly. The third way to form the air passage 41: the outer side of the bracket 2 used to connect one end of the atomization assembly is at least partially recessed to form a first ventilation groove, and the inner surface of the shell 1 is at least partially recessed to form a second ventilation groove, wherein the first ventilation groove and the second ventilation groove form the air passage 41. Of course, the air passage 41 can also be formed in other ways, which is not limited here.

[0054] In an embodiment, in combination with Figures 1 to 6The end face recess of the bracket 2 for connecting the atomization assembly is provided with a groove 24 for storing the condensed liquid or leakage liquid of the atomization assembly flowing into the power supply assembly 10. Since the ventilation groove 21 is communicated with the starting air channel 22, in order to reduce the leakage liquid in the groove 24 from entering the starting air channel 22 through the ventilation groove 21, the communication position between the ventilation groove 21 and the groove 24 is arranged to be higher than the bottom wall of the groove 24, so as to prevent the condensed liquid or leakage liquid in the groove 24 from entering the starting air channel 22 through the ventilation groove 21.

[0055] Please refer to Figure 7 and Figure 8 , Figure 7 is a third partial schematic view of the first embodiment of the power supply assembly of the present application; Figure 8 is a fourth partial schematic view of the connection between the top pin and the first elastic sheet in the first embodiment of the power supply assembly of the present application. In an embodiment, the power supply assembly 10 further comprises a control board 3, and the control board 3 and the starting air channel 22 are both located on the same side of the bracket 2, so that the microphone is located between the control board 3 and the bracket 2. In addition, the control board 3 and the bracket 2 are arranged in a stack, so that the power supply assembly 10 has a more compact structure and a smaller size. The bracket 2 for connecting one end of the atomization assembly is provided with at least two top pins 43, and the control board 3 for connecting one end of the atomization assembly is provided with at least two first elastic sheets 44, wherein the top pin 43 and the first elastic sheet 44 are correspondingly connected, one end of the first elastic sheet 44 is elastically connected with the end of the top pin 43, and the other end of the first elastic sheet 44 is connected to the control board 3, so that the first elastic sheet 44 can realize the electrical connection between the top pin 43 and the control board 3. The first elastic sheet 44 can have various structures, as long as it can realize the electrical connection between the top pin 43 and the control board 3.

[0056] In a specific embodiment, in order to improve the contact effect between the top pin 43 and the first elastic sheet 44, and to improve the electrical connection effect between the top pin 43 and the control board 3, one end of the top pin 43 is elastically clamped in the first elastic sheet 44, that is, the one end of the top pin 43 is clamped in the first elastic sheet 44 by the elastic force of the first elastic sheet 44, so that the top pin 43 and the first elastic sheet 44 can be in good contact, and the other end of the top pin 43 is used for connecting the atomization assembly, so as to realize the connection between the atomization assembly and the power supply assembly 10.

[0057] Please refer to Figure 9 , Figure 9 is Figure 1 the structure schematic view of the first elastic sheet and the patch. Please refer to Figure 7 and Figure 8Specifically, the first spring 44 includes a clamping portion (not shown in the figure) that clamps one end of the ejector 43. The clamping portion includes a first clamping arm 441, a second clamping arm 442, and a connecting portion 443. The first clamping arm 441 and the second clamping arm 442 are respectively located at the ends of the connecting portion 443, and the first clamping arm 441 and the second clamping arm 442 are arranged opposite each other. The first clamping arm 441 and the second clamping arm 442 are used to clamp one end of the ejector 43 to achieve clamping of the ejector 43.

[0058] The first clamping arm 441 and the second clamping arm 442 can be arranged in parallel, or can be gradually approached in a direction away from the connecting portion 443. Figure 9 As shown, in order to further guide the ejector pin 43 to be clamped between the first clamping arm 441 and the second clamping arm 442, the end of the first clamping arm 441 and the end of the second clamping arm 442 are respectively bent outward to form a guide structure 444. That is, the end of the first clamping arm 441 and the end of the second clamping arm 442 gradually move away from each other in a direction away from the connecting portion 443 to form a V-shaped guide structure 444. The guide structure 444 is used to guide the ejector pin 43 to be clamped between the first clamping arm 441 and the second clamping arm 442, thereby guiding the assembly of the ejector pin 43.

[0059] Furthermore, if Figure 9 As shown, the first clamping arm 441 and the second clamping arm 442 can first gradually approach each other and then gradually move away from each other in a direction away from the connecting portion 443. The minimum distance between the first clamping arm 441 and the second clamping arm 442 is used to clamp one end of the ejector pin 43, and the gradually moving away position between the first clamping arm 441 and the second clamping arm 442 is used to guide the ejector pin 43 into the clamping portion. Of course, in other embodiments, the first clamping arm 441 and the second clamping arm 442 can first be arranged parallel to each other in a direction away from the connecting portion 443 and then gradually move away from each other. In addition, to enhance the strength of the first spring piece 44, reinforcing ribs can be provided on the first clamping arm 441 and the second clamping arm 442 to enhance the strength.

[0060] See also Figure 10 and Figure 11 , Figure 10 This is a first partial schematic diagram of the second embodiment of the power supply assembly of the present application; Figure 11 yes Figure 10 The diagram shows an angled structure of the first spring piece 44. In other embodiments, the first spring piece 44 can also be configured in other structures, such as one end of the ejector pin 43 abutting against the end of the first spring piece 44. Because the first spring piece 44 is elastic, when the first spring piece 44 is deformed and subjected to force, the end of the first spring piece 44 can better abut against the ejector pin 43, thereby improving the contact performance between the ejector pin 43 and the first spring piece 44.

[0061] Specifically, the first elastic sheet 44 comprises at least one U-shaped plate 446, the U-shaped plates 446 are arranged in sequence, and the openings of the at least one U-shaped plate 446 are arranged towards the control plate 3. The one end of the needle 43 elastically abuts against one side of the U-shaped plate 446 closest to the needle 43, and the U-shaped plate 446 far away from the needle 43 is used for being connected to the control plate 3, that is, the electrical connection between the needle 43 and the control plate 3 can be realized through the at least one U-shaped plate 446. When the side of the U-shaped plate 446 close to the needle 43 is forced, it can recover elasticity according to itself, so as to abut against the one end of the needle 43.

[0062] The number of the U-shaped plates 446 can be one or more. When the number of the U-shaped plates 446 is more than one, the first elastic sheet 44 further comprises at least one arc-shaped plate 447, the number of the arc-shaped plates 447 is one or more, and the arc-shaped plates 447 are arranged between adjacent U-shaped plates 446. The U-shaped plates 446 and the arc-shaped plates 447 can be fixedly connected or integrally formed. Therefore, the first elastic sheet 44 can have a U-shaped, W-shaped, combined shape of several U-shaped and W-shaped, combined shape of several W-shaped, etc., and the specific shape of the first elastic sheet 44 is not limited here. In this embodiment, the first elastic sheet 44 is arranged in a W-shaped manner.

[0063] By arranging the first elastic sheet 44 in the above shape, the deformation amount and the service life of the first elastic sheet 44 can be ensured, and the needle 43 can be in good contact with the side of the U-shaped plate 446 in the first elastic sheet 44. In addition, compared with the direct clamping of the one end of the needle 44 in the first elastic sheet 44 in the above embodiment, the first elastic sheet 44 is in separate contact with the needle 44 in this embodiment, and the cooperation difficulty between the needle 44 and the first elastic sheet 44 is low.

[0064] In an embodiment, referring to Figure 7 , Figure 8 and Figure 9 , the control plate 3 further comprises a patch 45, and the patch 45 is used for fixing the first elastic sheet 44 on the control plate 3, so as to realize the stable connection between the first elastic sheet 44 and the control plate 3. In addition, in order to reduce the occupied volume of the first elastic sheet 44, a notch (not shown in the figure) can be formed on the end surface of the control plate 3 close to the atomization assembly. The first elastic sheet 44 is arranged in the notch, and the first elastic sheet 44 is connected to the control plate 3 through the patch 45. Through the above manner, the connection between the first elastic sheet 44 and the control plate 3 is more compact, and the internal volume occupation of the power supply assembly 10 is reduced. In other embodiments, notches are respectively formed on the opposite sides of the end surface of the control plate 3 close to the atomization assembly, and two first elastic sheets 44 are respectively arranged in the two notches.

[0065] The first elastic sheet 44 and the patch 45 are fixedly connected or integrally formed, so that the contact pin 43 can be better electrically connected to the control panel 3. The patch 45 and the connecting portion 443 of the first elastic sheet 44 are integrally formed.

[0066] Please refer to Figure 12 , Figure 12 is Figure 10 another angle structure diagram of the first elastic sheet. In combination with Figure 10 and Figure 11 , in another embodiment, the first elastic sheet 44 is open towards the patch 45, and the first elastic sheet 44 and the patch 45 are oppositely arranged. The end of the first elastic sheet 44 away from the contact pin is fixedly connected or integrally formed with the patch 45, that is, the first elastic sheet 44 is installed on the control panel 3 through the patch 45. The end of the first elastic sheet 44 close to the contact pin 44 can be compressed and deformed along the side direction of the patch 45, thereby controlling the compression deformation direction of the first elastic sheet 44 and preventing it from deviating from the direction and affecting the abutment of the end of the contact pin 43.

[0067] Further, the patch 45 is provided with sliding grooves 454 on both sides, and the U-shaped plate 446 is provided with a sliding protrusion 448 at the end of one side, wherein the sliding protrusion 448 is clamped on the side of the sliding groove 454. After the side of the U-shaped plate 446 is stressed, the sliding protrusion 448 can slide along the side of the sliding groove 454, thereby limiting the direction of the deformation of the first elastic sheet 44.

[0068] In order to reduce the volume occupied by the patch 45 inside the power supply assembly 10, the patch 45 can be provided with at least two clamping claws (not shown in the figure). The patch 45 is clamped on the control panel 3 through the clamping claws, which not only can realize stable connection between the patch 45 and the control panel 3, but also can reduce the volume occupation and realize compact structure. Figure 8 and Figure 9 In this embodiment, the patch 45 is square-shaped and includes three clamping claws. The three clamping claws are arranged on three adjacent sides of the patch 45, and the connecting portion 443 of the first elastic sheet 44 is arranged on the side of the patch 45 without the clamping claw. Figure 10 and Figure 11 In this embodiment, the patch 45 is rectangular-shaped and is symmetrically provided with two sides, and each side is provided with two clamping claws. The four clamping claws are used to clamp in the control panel 3.

[0069] In an embodiment, in combination with Figure 7The power supply assembly 10 further comprises a battery 5 for supplying power to the atomization assembly. The battery 5 is arranged on the control board 3, and the battery 5 is provided with electrode tabs 51, such as positive electrode tabs and negative electrode tabs, at an end close to the atomization assembly. In order to improve the good contact between the battery 5 and the control board 3, a second spring sheet 46 is arranged on the side of the control board 3 away from the support 2, the second spring sheet 46 is elastic, the electrode tabs 51 are elastically pressed on the second spring sheet 46, the second spring sheet 46 is deformed, thereby ensuring that the electrode tabs 51 are in close contact with the second spring sheet 46, so as to realize good electrical connection between the battery 5 and the control board 3.

[0070] Please refer to Figure 13 , Figure 13 is Figure 1 the second spring structure schematic diagram.
