DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] The power supply unit is an important component of the electronic atomization device. The power supply unit generally includes a shell, a battery arranged in the shell, and an electronic control module arranged in the shell. The bottom of the shell is sealed, and the top of the shell has an opening. The battery and the electronic control module are generally loaded into the shell from the top opening, which is inconvenient to disassemble and assemble. In order to ensure the reliability of the installation of the battery in the shell, the battery is generally fixed inside the shell by gluing, which makes the battery non-removable and the battery life cannot be achieved by replacing the battery, reducing the service life of the entire power supply unit. In addition. When the power supply unit is discarded, the battery cannot be removed for recycling, causing environmental pollution.

[0034] Based on the above problems, an embodiment of the present application provides a power supply unit 100 and an electronic atomization device, by configuring the shell 110 to have a bottom opening 112, installing the battery 122 on the battery rack 121, and detachably inserting the battery rack 121 into the shell 110 from the bottom opening 112, so that the battery 122 and the battery rack 121 can be conveniently disassembled from the bottom opening 112 of the shell 110, thereby facilitating the replacement of the battery 122.

[0035] See also Figure 1 and Figure 2 The embodiment of the present application provides an electronic atomization device, including a power supply unit 100 and an atomization unit 200. The power supply unit 100 is electrically connected to the atomization unit 200. The power supply unit 100 is used to supply power to the atomization unit 200. The atomization unit 200 is used to atomize the atomization medium into aerosol particles and deliver the generated aerosol particles to the oral cavity of the smoker.

[0036] Please also read Figures 1 to 6 The power supply unit 100 includes a housing 110, a battery assembly 120 and an electric control module 130. The battery assembly 120 includes a battery rack 121 and a battery 122. The housing 110 has an installation cavity 111 and a bottom opening 112 connected to the bottom of the installation cavity 111. The electric control module 130 is installed in the installation cavity 111. The battery 122 is installed in the battery rack 121. The battery rack 121 can be inserted into the installation cavity 111 from the bottom opening 112, and the end of the battery rack 121 away from the electric control module 130 can block the bottom opening 112; the battery rack 121 is detachably connected to the housing 110 and / or the electric control module 130, and the battery 122 is electrically connected to the electric control module 130.

[0037] The battery 122 is electrically connected to the electric control module 130 , and the electric control module 130 is electrically connected to the atomization unit 200 , so that the atomization unit 200 is powered by the battery 122 .

[0038] The battery 122 is installed in the battery holder 121 in a detachable manner, for example, the battery 122 is installed in the battery holder 121 in an interference fit manner, or the battery 122 can be installed by locking screws or snapping. In addition, the battery 122 can also be installed in the battery holder 121 in a non-detachable manner, so when the battery 122 needs to be replaced, the battery 122 and the battery holder 121 are removed from the housing 110 as a whole.

[0039] During assembly, the electronic control module 130 can be first installed into the shell 110, and then the battery 122 can be installed into the battery rack 121 to form a battery assembly 120. Then the battery rack 121 can be inserted into the installation cavity 111 from the bottom opening 112 of the shell 110 until the bottom of the battery rack 121 blocks the bottom opening 112, and the top of the assembled battery rack 121 abuts against the electronic control module 130. After being assembled, the battery 122 forms an electrical connection with the electronic control module 130.

[0040] In the embodiment of the present application, a bottom opening 112 communicating with the installation cavity 111 is formed on the shell 110, and the battery rack 121 is inserted into the installation cavity 111 from the bottom opening 112, and the end of the battery rack 121 away from the electric control module 130 can block the bottom opening 112. In addition, the battery rack 121 is detachably connected to the shell 110 and / or the electric control module 130, which is convenient for loading the battery 122 and the battery rack 121 into the shell 110 as a whole, and also convenient for removing the battery 122 and the battery rack 121 from the shell 110 as a whole, so as to facilitate the replacement of the battery 122 to achieve battery life. In addition, when the power supply unit 100 is discarded as a whole, the battery 122 can also be removed for recycling to reduce environmental pollution.

[0041] In one embodiment, see Figure 5 and Figure 7 The battery rack 121 includes a main body 1211 and an end cover 1212 which are connected to each other. The battery 122 is installed in the main body 1211. The main body 1211 is inserted into the installation cavity 111, and the end cover 1212 covers the outside of the bottom opening 112. During assembly, the battery 122 is loaded into the main body 1211, and then the main body 1211 is inserted into the installation cavity 111 from the bottom opening 112 until the end cover 1212 covers the outside of the bottom opening 112. That is, the end cover 1212 can be used as the bottom cover of the shell 110. When the battery rack 121 is assembled, the bottom opening 112 of the shell 110 can be covered at the same time. The structural design is simple, the structural design and manufacturing cost are low, and the assembly is simple.

[0042] In one embodiment, see Figure 7 The main body 1211 and the end cover 1212 are connected as one piece, for example, the main body 1211 and the end cover 1212 can be connected as one piece by injection molding, or can be formed by CNC machining of the same base member. It can be understood that in other embodiments of the present application, the main body 1211 and the end cover 1212 can also be processed independently and then fixed by bonding, screw locking or other methods, which is not limited here.

[0043] In one embodiment, the battery rack 121 is snap-fitted with the housing 110, and the battery rack 121 is snap-fitted with the electric control module 130. In this embodiment, the housing 110 and the electric control module 130 are snap-fitted with the battery rack 121 respectively, thereby improving the assembly stability and assembly balance of the battery rack 121 in the housing 110. It can be understood that in other embodiments of the present application, only the battery rack 121 and the electric control module 130 may be snap-fitted; or, only the battery rack 121 and the housing 110 may be snap-fitted.

[0044] In one embodiment, see Figure 5 The battery rack 121 includes a main body 1211 and an end cover 1212 which are connected to each other. The top of the main body 1211 is snap-fitted with the electric control module 130, and the bottom of the main body 1211 is snap-fitted with the shell 110. In this way, the opposite ends of the main body 1211 are snap-fitted with the electric control module 130 and the shell 110 respectively, thereby improving the assembly stability and firmness of the main body 1211 in the shell 110.

[0045] In one embodiment, at least one clamping connection is formed between the outer peripheral wall of the bottom of the main body 1211 and the inner peripheral wall of the bottom of the shell 110. Specifically, one clamping connection is formed between the outer peripheral wall of the bottom of the main body 1211 and the inner peripheral wall of the bottom of the shell 110, or multiple clamping connections distributed along the circumferential direction are formed between the outer peripheral wall of the bottom of the main body 1211 and the inner peripheral wall of the bottom of the shell 110.

[0046] In one embodiment, at least two snap connections are formed between the top of the main body 1211 and the electric control module 130 . When the main body 1211 is inserted into the housing 110 and moves toward the electric control module 130 , the top of the main body 1211 forms a snap connection with the electric control module 130 .

[0047] In one embodiment, see Figure 4A snap-fit ​​structure 140 is formed between the outer wall of the battery holder 121 and the inner wall of the shell 110. Specifically, an elastic portion 141 and a protrusion 142 protruding from the elastic portion 141 are formed on the outer wall of the battery holder 121, and a groove 143 is formed on the inner wall of the shell 110. When the battery holder 121 is inserted into the installation cavity 111, the outer wall of the battery holder 121 is fitted with the inner wall of the shell 110, and the protrusion 142 is elastically engaged with the groove 143. The setting of the elastic portion 141 enables the size of the protrusion 142 to be set larger to form a firm engagement with the groove 143, and the protrusion 142 can elastically abut against the inner wall of the shell 110 before being engaged in the groove 143, thereby reducing the friction between the protrusion 142 and the inner wall of the shell 110, reducing the difficulty of inserting the battery holder 121 into the shell 110, and also reducing the difficulty of separating the protrusion 142 from the groove 143 during disassembly.

[0048] In one embodiment, see Figure 4 The battery holder 121 includes a main body 1211 and an end cover 1212 that are connected to each other. The elastic portion 141 is formed on the outer wall of the main body 1211, and the elastic portion 141 is formed at a position of the main body 1211 close to the end cover 1212. The protrusion 142 is formed on the elastic portion 141, and the groove 143 forms the inner wall of the shell 110 and is close to the bottom end. The above arrangement enables the protrusion 142 to abut against the inner wall of the shell 110 when the battery holder 121 is inserted into the shell 110 and is close to the end position. After the protrusion 142 is inserted into the inner wall of the shell 110, it is quickly inserted into the groove 143, which reduces the length of the protrusion 142 abutting against the inner wall of the shell 110, that is, it reduces the difficulty of inserting the battery holder 121 into the shell 110.

[0049] In one embodiment, see Figure 7 The elastic portion 141 is a part of the outer wall of the battery holder 121. Specifically, the elastic portion 141 is formed by machining a U-shaped groove on the outer wall of the battery holder 121. The elastic portion 141 is surrounded by the U-shaped groove. The elastic portion 141 is disconnected from the battery holder 121 at least partially around the elastic portion 141, so that the elastic portion 141 has elasticity.

[0050] In one embodiment, see Figure 7 , an elastic portion 141 and a protrusion 142 are formed on the main body 1211. It can be understood that in other embodiments of the present application, two or more elastic portions 141 spaced apart along the circumferential direction may be formed on the main body 1211, a protrusion 142 is formed on each elastic portion 141, and a groove 143 is formed corresponding to each protrusion 142, which is not limited here.

[0051] In one embodiment, see Figure 3 and Figure 5 The main body 1211 is formed with a battery cavity 1215 that passes through one side of the main body 1211. The battery 122 is inserted into the battery cavity 1215 from one side of the main body 1211 and forms an interference fit with the battery cavity 1215. Specifically, a buffer pad 126 is installed on the top of the battery cavity 1215. The top of the battery 122 abuts against the top inner wall of the battery cavity 1215, and the bottom of the battery 122 abuts against the buffer pad 126, so that the battery 122 is limited in the battery cavity 1215.

[0052] In the above embodiment, in order to facilitate the installation of the battery 122 and to reduce the structural material of the battery rack 121, the battery rack 121 has only a partial structure along the circumference, so only one elastic portion 141 and protrusion 142 are provided in this embodiment.

[0053] In one embodiment, see Figure 7 In order to reduce the structural interference between the battery rack 121 and the battery 122, and also to reduce the material cost and weight of the battery rack 121, the battery rack 121 is formed with a plurality of long strip-shaped through holes 1214 extending longitudinally and spaced circumferentially.

[0054] In one embodiment, see Figure 4 and Figure 7 The battery holder 121 is arc-shaped and concave to form an unlocking portion 1213. The unlocking portion 1213 is formed at a position where the battery holder 121 is placed outside the housing 110 and adjacent to the elastic portion 141. Pressing the unlocking portion 1213 can drive the elastic portion 141 and the protrusion 142 to move away from the groove 143 to disengage from the groove 143. The elastic portion 141 is elastic, and the battery holder 121 itself also has a certain elasticity due to its frame structure. The unlocking portion 1213 is disposed adjacent to the elastic portion 141. When the unlocking portion 1213 is pressed, the unlocking portion 1213 generates elastic deformation from outside to inside and drives the elastic portion 141 and the protrusion 142 to move away from the groove 143, so that the protrusion 142 is disengaged from the groove 143, and the buckle is unlocked. In this embodiment, through the above-mentioned structural design, when it is necessary to disassemble the battery 122 and the battery holder 121, it is only necessary to press the unlocking portion 1213 outside the shell 110 to unlock the connection between the battery holder 121 and the shell 110, thereby easily removing the battery holder 121 from the shell 110; in addition, the arc-shaped concave setting of the unlocking portion 1213 can, on the one hand, thin the unlocking portion 1213 so that the unlocking portion 1213 has better elasticity and is easy to press and drive, and on the other hand, it also allows the unlocking portion 1213 to adapt to the curvature of the finger, thereby improving the comfort of finger pressing.

[0055] In one embodiment, see Figure 5 and Figure 6At least one clamping structure 150 is formed between one end of the battery rack 121 facing the electric control module 130 and one end of the electric control module 130 facing the battery rack 121. The connection between the battery rack 121 and the electric control module 130 is formed by the clamping structure 150 between the end faces of the battery rack 121 and the electric control module 130. The connection strength is stronger than the clamping between the battery rack 121 and the inner and outer side walls of the housing 110, which can improve the installation strength of the battery rack 121 inside the housing 110. At the same time, the structural positioning between the battery rack 121 and the electric control module 130 can be formed to ensure that the battery assembly 120 and the electric control module 130 are installed in the housing 110 in an orderly manner.

[0056] In one embodiment, see Figure 1 , Figure 6 and Figure 7 The housing 110, the battery rack 121 and the electronic control module 130 are all in a round and flat shape. Two clamping structures 150 are formed between the battery rack 121 and the electronic control module 130. The two clamping structures 150 are spaced apart along the width direction of the battery rack 121. The width direction of the battery rack 121 here refers to the lateral direction in which the size of the battery rack 121 is relatively large, that is, Figure 6 The present embodiment can improve the assembly stability of the battery rack 121 inside the housing 110 by providing two snap-fit ​​structures 150. It can be understood that in other embodiments of the present application, the housing 110, the battery rack 121 and the electronic control module 130 can also be cylindrical or in other shapes, and the number of snap-fit ​​structures 150 can also be one, three or more than three, which is not limited here.

[0057] In one embodiment, see Figure 4 The clamping structure 150 includes a first clamping portion (not shown in the figure) formed on the battery rack 121 and a second clamping portion 152 formed on the electric control module 130. The first clamping portion and the second clamping portion 152 form a plug-in fit and an elastic clamping along the plug-in direction of the battery rack 121. Specifically, when the battery rack 121 is inserted into the housing 110, the first clamping portion and the second clamping portion 152 form a plug-in fit and an elastic clamping during the plug-in process of the battery rack 121, that is, the first clamping portion and the second clamping portion 152 form an elastic plug-in fit, which can not only ensure the connection reliability between the battery rack 121 and the electric control module 130, but also facilitate the first clamping portion and the second clamping portion 152 to unlock each other.

[0058] In one embodiment, see Figure 6 and Figure 7The second clamping part 152 includes at least two spaced apart clamping jaws 151. The first clamping part can overcome the elastic force of each clamping jaw 151 under the action of external force to be inserted between each clamping jaw 151. The first clamping part can overcome the elastic force of each clamping jaw 151 under the action of external force to be removed from each clamping jaw 151. Among them, by providing at least two clamping jaws 151, the first clamping part can be clamped together by at least two clamping jaws 151 to ensure the reliability of the first clamping part. In addition, by providing at least two clamping jaws 151, each clamping jaw 151 has good elasticity, which is convenient for plugging and unplugging the first clamping part, that is, convenient for disassembling and assembling the battery holder 121.

[0059] In one embodiment, see Figure 6 A first limiting portion 1511 is formed on the clamping jaw 151, and each clamping jaw 151 encloses an insertion space 153 and a clamping space 154 which are separated by the first limiting portion 1511 and are interconnected; the first clamping portion includes a connecting portion 1522 formed on the battery rack 121 and a second limiting portion 1521 formed at an end of the connecting portion 1522 away from the battery rack 121, and the second limiting portion 1521 can be inserted into the clamping space 154 through the insertion space 153 and overcome the elastic force of each first limiting portion 1511, and the second limiting portion 1521 can overcome the elastic force of the first limiting portion 1511 under the action of external force and escape from the clamping space 154. Specifically, when the battery holder 121 is inserted into the shell 110, the second limiting portion 1521 is first inserted into the insertion space 153, and then passes through the insertion space 153 and pushes the first limiting portion 1511 to overcome the elastic force of the first limiting portion 1511 to snap into the snap-in space 154, wherein, due to the limitation of the second limiting portion 1521 by the first limiting portion 1511, the second limiting portion 1521 is limited in the snap-in space 154 in the absence of external force; when the user takes out the battery holder 121 along the opposite direction of the insertion of the battery holder 121, due to the pulling force of the user on the battery holder 121, the second limiting portion 1521 can overcome the elastic force of the first limiting portion 1511 and disengage from the snap-in space 154, and exit the insertion through the insertion space 153, thereby realizing the unlocking of the first snap-in portion and the second snap-in portion 152.

[0060] For details, please refer to Figure 6 The first limiting portion 1511 is protruded on the side of each clamping jaw 151 facing each other, and the gap between each clamping jaw 151 is smallest at the first limiting portion 1511. When the second limiting portion 1521 overcomes the elastic force of each first limiting portion 1511 from the insertion space 153 and enters the clamping space 154, the first limiting portion 1511 of each clamping jaw 151 blocks the second limiting portion 1521, so that the second limiting portion 1521 cannot withdraw from the clamping space 154.

[0061] In one embodiment, see Figure 6The longitudinal section of the first limiting portion 1511 is generally V-shaped. The first limiting portion 1511 includes a first guide surface 1512 and a second guide surface 1513 connected to each other. The first guide surface 1512 and the second guide surface 1513 are connected by an arc transition. The first guide surface 1512 is used to guide the second limiting portion 1521 to slide from the plug-in space 153 into the plug-in space 154. The second guide surface 1513 is used to guide the second limiting portion 1521 to slide from the plug-in space 154 into the plug-in space 153. In addition, please refer to Figure 6 A third guiding surface 1523 is formed on the first limiting portion 1511 , and the third guiding surface 1523 is used to cooperate with the second guiding surface 1513 to guide the second limiting portion 1521 to be inserted out of the insertion space 153 .

[0062] In a specific embodiment, the second clamping portion 152 includes two spaced apart clamping jaws 151, the first clamping portion can be clamped between the two clamping jaws 151, the first clamping portion includes a connecting portion 1522 and a second limiting portion 1521, the size of the connecting portion 1522 along the distribution direction of the two clamping jaws 151 is smaller than the size of the second limiting portion 1521 along the distribution direction of the two clamping jaws 151, when the second limiting portion 1521 is clamped into the clamping space 154, the connecting portion 1522 is located in the insertion space 153. It can be understood that in other embodiments of the present application, the number of clamping jaws 151 in the second clamping portion 152 can also be three, four or more than four, and the clamping jaws 151 are sequentially spaced and distributed along the circumferential direction, which is not a sole limitation here.
