DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0055] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0056] The electronic atomization device currently on the market includes an atomizer and a power supply assembly. The power supply assembly provides electrical energy to the atomizer to atomize the atomizing medium in the atomizer, thereby generating an aerosol. However, the assembly process of the power supply assembly is relatively cumbersome, the working hours are too long, and the cost is increased. At the same time, since the positive and negative electrodes of the battery need to be manually welded, there are defects such as cold welding, which further increases the cost of the power supply assembly.

[0057] Based on this, an embodiment of the present application provides a power supply component, the assembly process of which is relatively simple, which shortens the working hours and reduces the cost; and the positive and negative electrodes of the battery do not need to be welded to the first circuit board, avoiding the occurrence of adverse phenomena such as cold welding.

[0058] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0059] See also Figure 1 to Figure 2 , Figure 1 is a disassembly diagram of an electronic atomization device provided in one embodiment of the present application; Figure 2 This is provided by an embodiment of the present application Figure 1AA sectional view of the electronic atomization device shown. In the present embodiment, an electronic atomization device is provided, which can be used in the fields of beauty, medical treatment, electronic cigarettes, etc. The electronic atomization device includes an atomizer 10 and a power supply assembly 20. The power supply assembly 20 is electrically connected to the atomizer 10, and is used to supply power to the atomizer 10. The atomizer 10 is used to atomize the atomization medium to form an aerosol when powered on. The atomization medium can be a liquid medicine formed by dispersing a certain medicine in a liquid solvent, an oil with added aroma components, or any other liquid suitable for atomization, such as tobacco oil.

[0060] See also Figure 2 The atomizer 10 includes a second kit 1, an atomizer seat 2, a liquid storage shell 3, a vent pipe 4 and an atomizer core 5. The second kit 1 can be plastic. The atomizer seat 2 is arranged on the second kit 1 and forms the bottom surface of the atomizer 10. The vent pipe 4 is arranged in the liquid storage shell 3 and has a liquid inlet; and the vent pipe 4 and the liquid storage shell 3 are both arranged on the atomizer seat 2. The vent pipe 4 cooperates with the atomizer seat 2 and the liquid storage shell 3 to form a liquid storage chamber 31; the liquid storage chamber 31 is used to store the atomizing medium, and the atomizing medium enters the vent pipe 4 through the liquid inlet. The atomizer core 5 is arranged in the vent pipe 4 corresponding to the liquid inlet to atomize the atomizing medium entering the vent pipe 4 to form an aerosol, and the aerosol flows out of the atomizer 10 through the vent pipe 4.

[0061] The liquid storage shell 3 has a liquid injection port, and a liquid injection cap 32 is provided at the liquid injection port to block or expose the liquid injection port. The atomized medium can be injected into the liquid storage cavity 31 through the liquid injection port. The ventilation pipe 4 and the liquid storage shell 3 at least corresponding to the liquid storage cavity 31 can be transparent so that light can penetrate, so as to facilitate observation of the volume of the atomized medium in the liquid storage cavity 31 from the outside of the liquid storage shell 3, so as to reduce the risk of dry burning. The ventilation pipe 4 and the liquid storage shell 3 at least corresponding to the liquid storage cavity 31 can be made of transparent material, such as transparent glass, transparent plastic, etc.

[0062] In some embodiments, the atomizer seat 2 has a wire hole penetrating its upper and lower surfaces, and the surface of the atomizer seat 2 facing away from the ventilation tube 4 has a plug hole, which is configured to be plug-in connected to the electrode column 72d of the power supply assembly 20.

[0063] The atomizing core 5 includes a liquid guiding member 51, a heating element 52, and an atomizing electrode 53 electrically connected to the heating element 52. The liquid guiding member 51 may be a liquid absorbing cotton, and the liquid guiding member 51 is arranged corresponding to the liquid inlet, and is used to guide the atomizing medium entering the liquid inlet to the side surface of the liquid guiding member 51 away from the ventilation pipe 4. The heating element 52 is arranged on the side surface of the liquid guiding member 51 away from the ventilation pipe 4, and is used to atomize the atomizing medium guided thereto. At least part of the atomizing electrode 53 passes through the wire hole and extends into the plug hole through the side surface of the atomizing seat 2 away from the ventilation pipe 4; in this way, when the electrode column 72d of the power supply assembly 20 is inserted into the plug hole, the electrode column 72d can be further contacted and electrically connected with the atomizing electrode 53. At the same time, compared with the solution in which the atomizing electrode 53 extends vertically downward perpendicular to the atomizing seat 2, this solution extends the atomizing electrode 53 into the plug hole. This can prevent the atomizing electrode 53 from abutting against the power supply assembly 20 during the assembly of the atomizer 10 and the power supply assembly 20, resulting in the atomizer 10 and the power supply assembly 20 not being able to fit tightly together; or the atomizing electrode 53 being broken or damaging the power supply assembly 20 due to pressure.

[0064] The atomizing electrode 53 may extend to the side wall and / or bottom wall of the plug hole. Preferably, the atomizing electrode 53 may extend further to the bottom wall of the plug hole through the side wall of the plug hole, so that after the power supply assembly 20 and the atomizer 10 are assembled, the effective electrical connection between the electrode column 72d and the atomizing electrode 53 can be ensured. It can be understood that here, the electrode column 72d and the plug hole can also play a certain foolproof role.

[0065] Of course, in other embodiments, the atomizer 10 further includes structures such as a suction nozzle 33 and a suction nozzle cavity 34, which are similar to related structures in existing atomizers.

[0066] The specific structure and function of the power supply assembly 20 are introduced below.

[0067] Please see further Figure 3 and Figure 4 , Figure 3 yes Figure 1 AA section view of the power supply component; Figure 4 yes Figure 1 In this embodiment, a power supply assembly 20 is provided, and the power supply assembly 20 includes a housing 6 and a battery support assembly 7 and a battery 8 disposed in the housing 6.

[0068] The housing 6 includes an upper housing 61, a lower housing 62 and a light strip 63. The light strip 63 is injection molded on the outer side of the lower housing 62. The light strip 63 can be set as an LED light, which can not only emit a soft light marquee effect, but also indicate the volume of the atomized medium in the liquid storage chamber 31 through different colors, and can also indicate different concentrations and temperatures, remaining battery power, over-inhalation protection, etc. through warning colors.

[0069] The upper shell 61 and the lower shell 62 are integrally formed by in-mold injection molding, and define a receiving cavity; the battery holder assembly 7 is arranged in the receiving cavity. The shell 6 is formed by in-mold injection molding, and there is no need to assemble the upper shell 61, the lower shell 62 and the light strip 63. The shell 6 is quickly formed, the connection is firm, the reliability is good, the cost is low, the overall sense is strong, and the light strip 63 has a good light transmission effect.

[0070] In one embodiment, see Figures 5 to 8 , Figure 5 yes Figure 1 Schematic diagram of the overall structure of the battery bracket assembly; Figure 6 yes Figure 5 A sectional view of the battery bracket assembly taken along the AA direction; Figure 7 yes Figure 5 BB section view of the middle battery bracket assembly; Figure 8 yes Figure 5 The overall structure diagram of the battery support. The battery support assembly 7 includes a battery support 71 and a wire 72.

[0071] See also Figure 7 and Figure 8 The battery holder 71 is configured to fix the battery 8. The battery 8 may be a dry cell, a lead-acid battery, a lithium battery, etc. The battery holder 71 includes a first side wall 71a, a second side wall 71b, and a bridge portion 71c. The first side wall 71a and the second side wall 71b are arranged opposite to each other, and the first ends of the first side wall 71a and the second side wall 71b on the same side are connected by the bridge portion 71c; the second ends of the first side wall 71a and the second side wall 71b on the same side are both free ends.

[0072] As described above, the first side wall 71a and the second side wall 71b are connected by the bridge portion 71c, which can increase the stability and strength of the overall frame of the battery holder 71. In addition, since the second ends of the first side wall 71a and the second side wall 71b facing away from the bridge portion 71c are not connected together, the second ends of the first side wall 71a and the second side wall 71b have a certain elasticity, which is convenient for assembling the battery 8.

[0073] Among them, the battery holder 71 can be an injection molded part; that is, the first side wall 71a, the second side wall 71b and the bridging portion 71c are integrally formed by injection molding; in this way, the overall strength of the battery holder 71 can be increased, and the assembly process of the battery holder 71 is avoided, thereby speeding up the preparation efficiency and reducing the labor cost.

[0074] The wire 72 is arranged on the first side wall 71a and / or the second side wall 71b, and is exposed on the surface of one side away from the first side wall 71a through the bridge portion 71c. In this way, the first side wall 71a and the second side wall 71b can fix and limit the wire 72. Compared with the solution of placing the wire 72 in a disorderly manner in the housing 6, the neat layout of the wire 72 is improved, the risk of short circuit or open circuit caused by the crossing of the wire 72 due to the swinging back and forth of the battery holder 71 is reduced, and the battery holder 71 space is saved, and the design can be miniaturized to improve the portability of the electronic atomization device.

[0075] The wire 72 includes a positive wire and a negative wire, and the positive wire and the negative wire are respectively configured to be electrically connected to the positive and negative electrodes of the battery 8. Figure 3 , Figure 3 There are two wires 72, one is a positive wire and the other is a negative wire. In some embodiments, the positive wire and the negative wire are both arranged on the first side wall 71a; or the positive wire and the negative wire are both arranged on the second side wall 71b; or one of the positive wire and the negative wire is arranged on the first side wall 71a, and the other is arranged on the second side wall 71b.

[0076] In some embodiments, Figure 3 , at least a portion of one of the positive and negative wires is injection molded on the first side wall 71a, and at least a portion of the other is injection molded on the second side wall 71b. Compared with the wires 72 with different polarities being molded in-mold on the same side wall, this solution can prevent the positive and negative wires from crossing and causing a short circuit due to poor fixation during the in-mold injection molding process. The following embodiments of this application all take this as an example.

[0077] In some embodiments, part of the wire 72 is molded into the first side wall 71a and / or the second side wall 71b. The following embodiments of the present application all take this as an example. This solution can improve the neat layout of the wire 72, increase the connection reliability of the wire 72 and the corresponding side wall, and further reduce the risk of short circuit caused by crossing the wire 72. Among them, the wire 72 can be molded into the side wall by injection molding.

[0078] It should be noted that the injection molding involved in this application refers to in-mold injection molding, which means placing an already molded component into another mold and injection molding it with another plastic material. Therefore, the two components are connected together and do not require manual assembly, thereby improving production efficiency and reducing costs.

[0079] Of course, in some other embodiments, a limiting groove may be provided on the first side wall 71 a and / or the second side wall 71 b , and the wire 72 may be clamped in the limiting groove to limit and fix the wire 72 .

[0080] In some embodiments, see Figure 6 , each wire 72 includes a first wire portion 72a, a second wire portion 72b and a third wire portion 72c connected in sequence. The first wire portion 72a is injection molded on the first side wall 71a (or the second side wall 71b); and the first wire portion 72a extends along the extension direction Y of the first side wall 71a (or the second side wall 71b). The second wire portion 72b and the third wire portion 72c are injection molded on the bridge portion 71c; and the first wire portion 72a and the second wire portion 72b are inclined at a first preset angle, and the second wire portion 72b and the third wire portion 72c are inclined at a second preset angle. Compared with the wire 72 distributed in a straight line, the above scheme avoids the phenomenon that the wire 72 is easily pulled out from the battery holder 71, thereby increasing the stability of the wire, that is, the electrical connection is more stable. Among them, the first preset angle and / or the second preset angle can be 60°, 90°, 120°, etc.

[0081] In a specific embodiment, the first wire portion 72a and the third wire portion 72c are arranged in parallel, the extension direction Y of the second wire portion 72b is perpendicular to the first wire portion 72a, and the connection between the first wire portion 72a and the second wire portion 72b is chamfered; the connection between the third wire portion 72c and the second wire portion 72b is also chamfered to reduce the risk of breakage of the wire 72 at the bend.

[0082] In some embodiments, the battery holder assembly 7 further includes an electrode column 72d, which is in contact and electrically connected with a portion of the wire 72 exposed from the surface of the bridge portion 71c, for example, is electrically connected with an end of the third wire portion 72c away from the second wire portion 72b, and the electrode column 72d is configured to be electrically connected to the atomizing electrode 53 of the atomizer 10 to supply power to the atomizer 10. Specifically, when the power supply assembly 20 is connected to the atomizer 10, the electrode column 72d extends into the plug hole of the atomizer 10 to be plug-in connected to the atomizer 10, and is in contact and electrically connected with the atomizing electrode 53.

[0083] In some specific embodiments, the electrode column 72d can be a part of the wire 72; that is, at least part of the wire 72 protrudes from the bridging portion 71c to form the electrode column 72d. Specifically, part of the third wire portion 72c is formed by injection molding in the bridging portion 71c, and the remaining part protrudes from the bridging portion 71c to form the electrode column 72d. In this way, there is no need to set up another structural member as the electrode column 72d, thereby avoiding undesirable phenomena such as cold welding between the electrode column 72d and the wire 72. At the same time, part of the third wire portion 72c is formed by injection molding in the bridging portion 71c, and the bridging portion 71c can play a certain supporting role for the third wire portion 72c, so as to enhance the supporting strength of the third wire portion 72c and reduce the risk that the third wire portion 72c is bent during the connection process with the atomizer 10 and cannot be inserted into the plug hole to achieve effective electrical connection with the atomizing electrode 53.

[0084] Of course, in some other embodiments, the electrode column 72d may be a conductive structure different from the wire 72, and the electrode column 72d may be a columnar body with a certain support strength. In this way, the support strength of the electrode column 72d can be effectively guaranteed. In this embodiment, the electrode column 72d can also serve as a positioning structure, which plays a certain foolproof role in the assembly process of the power supply assembly 20 and the atomizer 10.

[0085] In some embodiments, the electrode column 72d includes two, namely a positive electrode column and a negative electrode column, the positive electrode column and the negative electrode column are electrically connected to the positive and negative electrode wires respectively, and are configured to be electrically connected to the two atomizing electrodes 53 of the atomizer 10.

[0086] In some embodiments, the battery holder 71 can be integrally formed with the wire 72 by injection molding. In this way, there is no need to assemble the wire 72 and the battery holder 71; and the connection reliability between the battery holder 71 and the wire 72 is better, the wire 72 is not easy to fall off or be pulled out from the battery holder 71, and the wire 72 is not messy, does not entangle with each other to increase space, and improves the miniaturization of the product, which is convenient to carry.

[0087] In some embodiments, see Figure 8 The outer side surface of the first side wall 71a and / or the second side wall 71b is provided with a plurality of positioning grooves 711, and the plurality of positioning grooves 711 are arranged at intervals along the extension direction Y of the first side wall 71a or the second side wall 71b, and each positioning groove 711 extends along a direction (hereinafter defined as a circumferential direction) perpendicular to the extension direction Y of the first side wall 71a or the second side wall 71b. In this way, during the process of injection molding the battery holder 71, the lead 72 can be clamped and fixed by the protrusions at the positions of the positioning grooves 711 of the mold, so as to reduce the risk of the lead 72 being twisted during the injection molding process.

[0088] The outer side walls of the first side wall 71a and the second side wall 71b are both provided with positioning grooves 711, and the positioning grooves 711 extend from one side edge of the side wall to the other side edge along the circumferential direction of the side wall.

[0089] As described above, since the first side wall 71a and / or the second side wall 71b have the positioning groove 711, the positioning groove 711 will affect the strength of the side wall where it is located. In order to increase the strength of the first side wall 71a or the second side wall 71b, in some embodiments, the outer wall surface of the first side wall 71a and / or the second side wall 71b further has a plurality of first convex ribs 712 and / or second convex ribs 713.

[0090] In a specific embodiment, the outer wall surfaces of the first side wall 71a and the second side wall 71b both have a plurality of first convex ribs 712 and a plurality of second convex ribs 713, and the plurality of first convex ribs 712 and the plurality of second convex ribs 713 are arranged on the outer wall surfaces of the first side wall 71a and the second side wall 71b in the same or similar manner; the following description is made taking the outer wall surface of the first side wall 71a having a plurality of first convex ribs 712 and a plurality of second convex ribs 713 as an example.

[0091] A plurality of first convex ribs 712 are arranged at intervals along the extension direction Y of the first side wall 71a, and each first convex rib 712 extends in a direction perpendicular to the extension direction Y of the first side wall 71a. In this way, the first convex ribs 712 can enhance the strength of the first side wall 71a along its circumferential direction, prevent bending deformation after injection molding, and maintain the consistency of the first side wall 71a and / or the second side wall 71b without deformation.

[0092] The second rib 713 extends along the extension direction Y of the first side wall 71a, and a second rib 713 is provided between each two adjacent positioning grooves 711. In this way, the second rib 713 can enhance the strength of the first side wall 71a along its extension direction Y to prevent deformation.

[0093] In some embodiments, in combination Figure 8 , the inner surface of the first side wall 71a and / or the second side wall 71b is injection molded to form a limiting portion 714; the contour of the limiting portion 714 matches the contour of the outer wall surface of the side wall of the battery 8. In this way, the side wall of the battery 8 can be supported by the limiting portion 714 to reduce the risk of the battery 8 falling off the battery holder 71; at the same time, the limiting portion 714 can play a certain fool-proof role in the process of installing the battery 8 to the battery holder 71. In addition, the limiting portion 714 is formed by injection molding. On the one hand, the limiting portion 714 can be formed simultaneously in the process of injection molding the battery holder 71, and the process will not be increased; on the other hand, compared with the solution of adding a limiting structure to form the limiting portion 714, the assembly process is omitted, and the connection reliability with the first side wall 71a or the second side wall 71b of the battery holder 71 is better, and the support and limiting effect of the battery 8 is more guaranteed.

[0094] In some embodiments, in combination Figure 7 and Figure 8The bridging portion 71c includes: a first bridging plate 715, a second bridging plate 716 and a support plate 717. The first bridging plate 715 and the second bridging plate 716 are connected to the first end of the first side wall 71a and the second side wall 71b at intervals along the extension direction Y of the battery holder 71. Among them, the first bridging plate 715 is located on the side of the second bridging plate 716 close to the first side wall 71a. The first bridging plate 715 and the second bridging plate 716 are both plate-shaped. The support plate 717 is connected between the first bridging plate 715 and the second bridging plate 716, and is respectively connected to the ends of the first side wall 71a and the second side wall 71b, and cooperates with the first bridging plate 715 and the second bridging plate 716 to form at least one first cavity 718. At least part of the wire 72 is injection molded in the support plate 717 and exposed from the side of the second bridging plate 716 away from the first bridging plate 715.

[0095] In one embodiment, in combination Figure 7 The support plate 717 is connected to the middle position of the first bridge plate 715 and the second bridge plate 716, so as to cooperate with the first bridge plate 715 and the second bridge plate 716 on both sides of the support plate 717 to form a first cavity 718. The first cavity 718 can store materials that slide or fall from the surface of the second bridge plate 716 to prevent them from falling to the installation position of the battery 8, thereby avoiding explosion caused by battery disconnection or puncture, thereby improving safety in use.

[0096] In addition, compared with the above-mentioned scheme in which the bridge portion 71c has a block structure, that is, the bridge portion 71c does not form the first cavity 718, the thickness of the first bridge plate 715 and the second bridge plate 716 is relatively small. In the process of injection molding the bridge portion 71c, the thickness of the first bridge plate 715 and the second bridge plate 716 is easier to control, which is beneficial to improve the level of the side surface of the second bridge portion 71c away from the first bridge plate 715, thereby improving the level of the side surface of the power supply component 20 that contacts the atomizer 10, and then improving the sealing of the connection between the power supply component 20 and the atomizer 10.

[0097] In some embodiments, see Figure 5 and Figure 6 The battery holder assembly 7 also includes: a sealing seat 73 and a first circuit board 74. The first circuit board 74 is arranged on the sealing seat 73 and connected to the wire 72. The battery holder 71 is injection molded on the first circuit board 74 and is sealed and connected to the first circuit board 74 through the sealing seat 73. The sealing seat 73 can be plastic, so when the battery holder 71 is injection molded, the sealing seat 73 and the first circuit board 74 are implanted into the mold of the battery holder 71, and the plastic slurry is injected into the mold to mold the battery holder 71. At this time, the battery holder 71 and the sealing seat 73 are fused to form a whole, thereby fixing the first circuit board 74 to avoid poor electrical contact caused by shaking.

[0098] In a specific embodiment, the first circuit board 74 has a conductive hole; a portion of the wire 72 extends into the conductive hole and is electrically connected to the first circuit board 74. Compared with the solution of welding the wire 72 and the first circuit board 74 to achieve electrical connection, it can prevent the occurrence of poor welding and other undesirable phenomena, and can also save the production cost caused by this, improve production efficiency, reduce costs, and have good consistency of finished products.

[0099] In some embodiments, see Figure 3 and Figure 5 , the first circuit board 74 is also provided with an electrode sleeve 741, a charging interface 742 and an air inlet 743. The electrode sleeve 741 is riveted and formed on the side surface of the first circuit board 74 facing the battery holder 71; the electrode sleeve 741 is configured to be sleeved with the power supply electrode of the battery 8. After the battery 8 is installed in the battery holder 71, the power supply electrode of the battery 8 extends into the electrode sleeve 741 and contacts and electrically connects with the first circuit board 74. This solution does not require welding wires, and there is no need to assemble the electrode sleeve 741 separately, which shortens the processing time, reduces production costs, and has good electrical connection stability.

[0100] Combination Figure 4 and Figure 5 The charging interface 742 is disposed on the side of the first circuit board 74 away from the electrode sleeve 741. The sealing seat 73 and the lower shell 62 are provided with a through hole corresponding to the position of the charging interface 742. The charging interface 742 is exposed from the shell 6 through the through hole and is configured to be electrically connected to an external power source to charge the battery 8.

[0101] During the inhalation process, external gas enters the power supply component 20 through the air inlet 743, and flows out of the power supply component 20 through the first cavity 718, the through hole formed by the edge of the second bridging plate 716 and the inner surface of the first kit 11, and enters the ventilation tube 4 of the nebulizer 10 to take away the aerosol formed by atomization.

[0102] The battery holder assembly 7 provided in this embodiment includes a battery holder 71 and a wire 72. The battery holder 71 is configured to fix the battery 8; and the battery holder 71 includes a first side wall 71a, a second side wall 71b and a bridge portion 71c; the first side wall 71a and the second side wall 71b are arranged opposite to each other, and the ends of the first side wall 71a and the second side wall 71b located on the same side are connected by the bridge portion 71c. The battery holder assembly 7 is provided with the wire 72 on the first side wall 71a and / or the second side wall 71b, and is exposed on the surface of one side away from the first side wall 71a through the bridge portion 71c; compared with the solution of placing the wire 72 in a disorderly manner, the neat layout of the wire 72 is improved, the risk of short circuit or open circuit caused by the crossing of the wire 72 due to the swinging back and forth of the battery holder 71 is reduced, and the space of the battery holder assembly 7 can be reduced to realize the miniaturization of the product, and it can also be integrally formed by implanting a mold to improve production efficiency and reduce costs. At the same time, the first side wall 71a and the second side wall 71b of the battery holder 71 are connected by the bridging wall, which can increase the stability and strength of the overall frame of the battery holder 71. In addition, since the ends of the first side wall 71a and the second side wall 71b away from the bridging portion 71c are not connected together, the ends of the first side wall 71a and the second side wall 71b have a certain elasticity, which is convenient for assembling the battery 8.

[0103] In some embodiments, please refer back to Figure 3 and Figure 4 The power supply assembly 20 further includes a second circuit board 9a and a light emitting element 9b. The second circuit board 9a is disposed on the side of the bridge portion 71c away from the first side wall 71a and is electrically connected to the wire 72 of the battery holder assembly 7.

Part of the side wall of the first assembly 11 is clamped between the housing 6 and the battery holder 71 to be sealed and connected to the housing 6 and the battery holder 71.

In addition, the first set 11 can also be transparent and light-transmissive, and the light beam of the light emitting element 9b can penetrate the first set 11 and irradiate the atomizer 10. The first set 11 can be a plastic part.

[0108] Combination Figure 2 When the atomizer 10 is connected to the power supply assembly 20 , the second assembly 1 is sleeved on the outside of the first assembly 11 , and the first assembly 11 abuts against a surface of the atomizer seat 2 facing the power supply assembly 20 .

[0109] Specifically, the first set 11 is surrounded by an upper cavity 113 and a lower cavity 114. The first set 11 is sleeved on the outer side of the bridge portion 71c through the lower cavity 114 and fits tightly with the circumferential side wall of the bridge portion 71c. The upper cavity 113 and the lower cavity 114 share a bottom wall; the electrode hole 111 and the air hole 112 are specifically opened on the shared bottom wall and penetrate the upper and lower surfaces of the shared bottom wall, so that the electrode column 72d can enter the upper cavity 113 through the electrode hole 111. Part of the atomizer seat 2 extends into the upper cavity 113 and is connected to the electrode column 72d.

[0110] In some embodiments, see Figure 1 and Figure 2 The electronic atomization device also includes a third kit 30, which is injection molded on at least part of the periphery of the first kit 11 and the second kit 1, so as to be fused and sealed with the first kit 11 and the second kit 1, so that the electronic atomization device forms an integrally molded whole.
