[0032] An electronic atomization apparatus generally includes a battery assembly and an atomizer. The battery assembly is configured to supply power to the atomizer. After being powered on, the atomizer is configured to heat and atomize an atomization medium to produce an aerosol. The atomizer is a disposable part, and the battery assembly is a recyclable part. Currently, the battery assembly and the atomizer are generally connected through magnet adsorption. In addition, an elastic pin is disposed in the battery assembly, an ejector pin is disposed in the atomizer, and an electrical connection between the battery assembly and the atomizer is formed through elastic contact between the elastic pin and the ejector pin. However, because a plurality of magnets, a plurality of elastic pins, and a plurality of ejector pins need to be disposed, costs of the atomizer are high. This is not conducive to a disposable design of the atomizer, and also makes costs of the entire electronic atomization apparatus relatively high.

[0033] To resolve the above problems, embodiments of this application provide a battery assembly 100 and an electronic atomization apparatus. A pin electrode 120 is disposed in the battery assembly 100, and the pin electrode 120 may extend into the atomizer 200 to be electrically connected to a heating element 210 of the atomizer 200. In this case, an ejector pin design in the atomizer 200 can be saved. In addition, the battery assembly 100 and the atomizer 200 are clamped, so that a magnet design in the atomizer 200 can be saved, thereby reducing structural costs of the atomizer 200, facilitating a disposable design of the atomizer 200, and also reducing the costs of the entire electronic atomization apparatus.

[0034] As shown in FIG. 1, an embodiment of this application provides an electronic atomization apparatus including an atomizer 200 and a battery assembly 100. The battery assembly 100 is electrically connected to the atomizer 200. The battery assembly 100 is configured to supply power to the atomizer 200. The atomizer 200 is configured to atomize an atomization medium into aerosol particles and deliver the generated aerosol particles to an oral cavity of a smoker.

[0035] As shown in FIG. 2 to FIG. 4, the battery assembly 100 provided in this embodiment of this application is described. The battery assembly 100 includes a pin electrode 120 and a first connection structure 114 for detachably connecting to an atomizer 200. The atomizer 200 includes a heating element 210. When the battery assembly 100 is connected to the atomizer 200, the pin electrode 120 is inserted into the atomizer 200 to be electrically connected to the heating element 210 of the atomizer 200.

[0036] The pin electrode 120 is inserted into the atomizer 200 to be electrically connected to the heating element 210 of the atomizer 200. Specifically, the pin electrode 120 is directly electrically connected to an electrode on the heating element 210. This does not include a case in which the pin electrode 120 is indirectly electrically connected to the heating element 210 by using another conductive element.

[0037] Based on the battery assembly 100 in this embodiment of this application, the pin electrode 120 is disposed in the battery assembly 100, and the pin electrode 120 may be inserted into the atomizer 200 to be directly electrically connected to the heating element 210 of the atomizer 200, thereby eliminating an elastic pin in the atomizer 200, simplifying the structure of the atomizer 200, and reducing costs of the atomizer 200. In addition, the first connection structure 114 is disposed in the battery assembly 100, so that a detachable connection is formed between the battery assembly 100 and the atomizer 200, thereby eliminating magnets in the battery assembly 100 and the atomizer 200, and reducing the costs of the atomizer 200 and costs of the battery assembly 100. In general, based on the battery assembly 100 in this application, through the design of the pin electrode 120 and the first connection structure 114, the structure of the atomizer 200 matching the battery assembly 100 is caused to be simpler and the costs are lower. This is conducive to disposable use of the atomizer 200, and structural costs of the entire electronic atomization apparatus are also reduced.

[0038] In an embodiment, as shown in FIG. 2 to FIG. 4, the battery assembly 100 further includes a battery holder 110 and an elastic member 130, the battery holder 110 is clamped to the atomizer 200, the elastic member 130 abuts between the battery holder 110 and the pin electrode 120 to elastically abut the pin electrode 120 against the heating element 210. The elastic member 130 is disposed to cause the pin electrode 120 to elastically abut against the heating element 210, thereby improving the connection stability between the pin electrode 120 and the heating element 210 and ensuring that the battery assembly 100 supplies power to the atomizer 200 well. It may be understood that in another embodiment of this application, the battery holder 110 and the atomizer 200 may alternatively be connected in another manner, such as interference fit, bonding, a magnetic connection, or a suction cup connection.

[0039] In an embodiment, as shown in FIG. 4, a limiting portion 121 is formed on the outer side wall of the pin electrode 120, the elastic member 130 abuts between the battery holder 110 and the side of the limiting portion 121 away from the heating element 210, and a movement stroke of the pin electrode 120 is limited by the battery holder 110. The above structural design causes the elastic member 130 to exert elastic force on the pin electrode 120 toward the heating element 210, so that the pin electrode 120 always remains abutting against the heating element 210 after being assembled, and has abutting force. In addition, the movement stroke of the pin electrode 120 away from the battery holder 110 is limited by the battery holder 110, thereby preventing the pin electrode 120 from detaching from the battery holder 110 under an action of the elastic member 130.

[0040] In an embodiment, as shown in FIG. 4 and FIG. 6, the battery holder 110 includes a main body portion 111 clamped to the atomizer 200 and at least two hooks 112 formed on the main body portion 111. The hooks 112 encloses an accommodating space 113 for accommodating the elastic member 130, the pin electrode 120 extends through the accommodating space 113, and the limiting portion 121 is movably limited in the accommodating space 113. The hooks 112 and the accommodating space 113 enclosed by the hooks 112 are disposed, so that not only the elastic member 130 and the limiting portion 121 may be accommodated by using a simple structure, but also the elastic member 130 and the limiting portion 121 may be easily installed into the accommodating space 113 from the outside through the hooks 112 because the hook 112 is elastic. The assembly is convenient. It may be understood that in another embodiment of this application, a cylinder for installing the elastic member 130 may alternatively be directly formed on the battery holder 110, and then a limiting structure for limiting the pin electrode 120 is formed on the cylinder. This is not uniquely limited herein.

[0041] In an embodiment, as shown in FIG. 4, the elastic member 130 is a cylindrical spring. The limiting portion 121 is an annular plate extending along a circumferential direction of the pin electrode 120. The hook 112 includes a connecting portion 1121 extending from the main body portion 111 toward the atomizer 200 and a hook portion 1122 formed at an end of the connecting portion 1121 away from the main body portion 111. When the elastic member 130 abuts between the limiting portion 121 and the main body portion 111, the limiting portion 121 abuts against the hook portion 1122, so that the limiting portion 121 can be limited by the hook portion 1122, to prevent the limiting portion 121 from being separated from the accommodating space 113. During assembly, the elastic member 130 and the limiting portion 121 only need to press the hook portion 1122 from the top of each hook 112 to cause the hook portion 1122 and the connecting portion 1121 to deform, thereby installing the elastic member 130 and the limiting portion 121 into the accommodating space 113. An overall structure thereof is simple and material costs can be saved.

[0042] In an embodiment, as shown in FIG. 4 and FIG. 6, two hooks 112 is formed on a side, facing the atomizer 200, of the main body portion 111 corresponding to one pin electrode 120, and the two hooks 112 are spaced apart opposite to each other to enclose the accommodating space 113. A structure is simple and assembly resistance to the elastic member 130 and the limiting portion 121 is small. It may be understood that in another embodiment of this application, three or more hooks 112 may be formed on the main body portion 111 corresponding to one pin electrode 120, and the hooks 112 are spaced apart in sequence along a circumferential direction to enclose the accommodating space 113. This is not uniquely limited herein.

[0043] In an embodiment, as shown in FIG. 4, the battery assembly 100 includes two pin electrodes 120, and two groups of hooks 112 and two elastic members 130 are separately disposed on the main body portion 111 corresponding to the two pin electrodes 120.

[0044] In an embodiment, as shown in FIG. 3 and FIG. 5, the battery assembly 100 further includes a battery 140 and a circuit board 150. The battery 140 and the circuit board 150 are both installed on the battery holder 110. The battery 140 is electrically connected to the circuit board 150. The two pin electrodes 120 are electrically connected to the circuit board 150 through a wire.

[0045] In an embodiment, as shown in FIG. 3 to FIG. 6, the main body portion 111 includes an accommodating cavity 1111 for accommodating the battery 140 and the circuit board 150. The main body portion 111 includes a top plate 1112 located at the top of the accommodating cavity 1111, two first electrode holes 1113 extending through are formed on the top plate 1112, and a group of hooks 112 is formed at a position corresponding to each first electrode hole 1113 on the side of the top plate 1112 away from the battery 140. The two pin electrodes 120 respectively extend through two first electrode holes 1113, one end of the pin electrode 120 extends into the accommodating cavity 1111 to be electrically connected to the circuit board 150 through a wire, and the other end of the pin electrode 120 extends through the accommodating space 113 and extends into the atomizer 200 to be electrically connected to the heating element 210.

[0046] In an embodiment, as shown in FIG. 4 and FIG. 6, the first connection structure 114 includes an elastic arm 1141 and a clamping portion 1142 formed on the elastic arm 1141, and the clamping portion 1142 is used to form a clamping connection to the atomizer 200. The elastic arm 1141 is disposed to increase the elasticity of the first connection structure 114, thereby facilitating a clamping connection between the clamping portion 1142 and the atomizer 200, and also facilitating detachment and separation of the clamping portion 1142 from the atomizer 200.

[0047] In an embodiment, as shown in FIG. 4 and FIG. 6, a pressing portion 1143 is formed on the elastic arm 1141, the pressing portion 1143 and the clamping portion 1141 are formed on a same side of the elastic arm 1141, and the pressing portion 1143 is pressed, so that the elastic arm 1141 and the clamping portion 1142 can be driven to separate from the atomizer 200. The pressing portion 1143 is formed between two ends of the elastic arm 1141. Because the pressing portion 1143 and the clamping portion 1142 are formed on the same side of the elastic arm 1141, when the pressing portion 1143 is pressed, the elastic arm 1141 can be driven to deform in a pressing direction, and the clamping portion 1142 is driven to move in the pressing direction. The pressing direction is just opposite to a convex direction of the clamping portion 1142 on the elastic arm 1141, so that the clamping portion 1142 can be driven to separate from the atomizer 200, thereby implementing separation of the battery assembly 100 from the atomizer 200.

[0048] In an embodiment, as shown in FIG. 1 and FIG. 6, the battery assembly 100 further includes a battery holder 110 and a housing 160. The battery holder 110 is accommodated in the housing 160, and a clamping connection is formed between the battery holder 110 and the atomizer 200 in the housing 160. A communication groove 161 is formed on the side wall of the housing 160, and the pressing portion 1143 extends through the communication groove 161. A plug-in connection between the pressing portion 1143 and the communication groove 161 allows a user to drive the pressing portion 1143 outside the housing 160 for an easy operation, and also can implement installation and positioning between the battery holder 110 and the housing 160.

[0049] In an embodiment, as shown in FIG. 6, the pressing portion 1143 is a convex block that is convexly disposed on the elastic arm 1141, and the convex block is pressed to drive the elastic arm 1141 and the clamping portion 1142 to separate from the atomizer 200.

[0050] Optionally, as shown in FIG. 6, the pressing portion 1143 is of a square shape. It may be understood that, in another embodiment, a cross section of the pressing portion 1143 may alternatively be circular, waist-shaped, diamond-shaped, polygonal, or irregular. This is not uniquely limited herein.

The at least two first connection structures 114 and the at least two second connection structures 224 are disposed, so that the battery holder 110 and the atomizer 200 are firmly clamped, and clamping force is evenly distributed circumferentially. In addition, the second connection structures 224 are distributed on the periphery of the atomizer base 220, to prevent the second connection structure 224 from affecting the atomization cavity 223 and other structures inside the atomizer base 220.

[0054] In an embodiment, as shown in FIG. 4, the first connection structure 114 includes an elastic arm 1141 formed on the side of the main body portion 111 facing the atomizer base 220 and the clamping portion 1142 formed at an end of the elastic arm 1141 away from the main body portion 111. The second connection structure 224 includes a plug-in channel 2221 and a clamping channel 2222 that communicate with each other.
