[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the template description herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figures 1 to 4 As shown, some embodiments of the present invention provide a battery, which is mainly used in an atomizing device to prevent the liquid in the atomizing device from contacting the sensor in the battery, thereby increasing the service life of the battery and the sensor, and arranging the battery separately for easy maintenance or replacement.

[0044] The battery includes a housing 100 , a battery cell 200 , a controller 300 and a sensor 400 .

[0045] The shape of the housing 100 can be any one of cylindrical, polygonal, square, elliptical or spherical, or a combination of two or more, and can be specifically set according to actual conditions.

[0046] In this embodiment, the cylindrical shape of the housing 100 is taken as an example for detailed description as follows.

[0047] The housing 100 defines a receiving cavity 110 having an opening, and the opening is provided on one side of the axial direction of the housing 100 . A first through hole 120 communicating with the receiving cavity 110 is provided on a side wall of the housing 100 .

[0048] In addition, the battery cell 200 is accommodated in the accommodating cavity 110, and the side wall of the battery cell 200 contacts the inner wall of the outer shell 100, so that the outer shell 100 provides a limiting and protective function for the battery cell 200, thereby ensuring the stability of the battery cell 200 in the accommodating cavity 110 along a direction perpendicular to the axis of the outer shell 100.

[0049] The controller 300 is at least partially accommodated in the accommodating cavity 110, and the controller 300 is connected to the housing 100. The connection between the controller 300 and the housing 100 includes a snap connection or an adhesive connection, which can be specifically set according to actual conditions.

[0050] In this embodiment, the controller 300 is electrically connected to the battery cell 200. It should be noted that the connection between the controller 300 and the battery cell 200 includes at least one of linear connection, connector contact connection and plug-in connection.

[0051] Specifically, the controller 300 is at least partially spaced from the battery cell 200, that is, a portion of the controller 300 facing the battery cell 200 is spaced from the battery cell 200, thereby defining a first cavity 130 in communication with the first through hole 120 between the controller 300, the battery cell 200, and the housing 100. The controller 300 defines an airflow channel 310 in communication with the first cavity 130, so that gas in the first cavity 130 can be discharged through the airflow channel 310. It is understandable that external gas can enter the first cavity 130 through the first through hole 120 and be discharged through the airflow channel 310.

[0052] It should be noted that the sensor 400 described in this embodiment is an air pressure sensor or an air flow sensor, so that the air pressure or air flow changes in the first cavity 130 are detected by the sensor 400 .

[0053] Furthermore, the sensor 400 is arranged on the side of the controller 300 facing the battery cell 200, and the sensor 400 is electrically connected to the controller 300. The detection end of the sensor 400 is arranged at the end where the airflow channel 310 is connected to the first cavity 130, so as to detect the airflow or air pressure changes in the airflow channel 310 through the detection end of the sensor 400.

[0054] By placing sensor 400 in the battery and connecting it to controller 300, sensor 400 detects changes in air pressure in airflow channel 310 in the battery. Sensor 400 then transmits the detected airflow or air pressure changes to controller 300 via a signal. Controller 300 receives the signal, determines the signal, and executes further control based on the determination. By placing sensor 400 in the battery, housing 100 protects sensor 400, preventing external liquids from coming into contact with sensor 400, thereby ensuring the accuracy of sensor 400 during detection and its service life.

[0055] It is understandable that when the battery provided in the present application is applied to the atomization device, it can effectively prevent the atomized liquid or condensed liquid in the atomization device from contacting the sensor 400, thereby ensuring the sensitivity of the sensor 400 during operation.

[0056] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, along the circumference of the housing 100, a portion of the side wall of the housing 100 is recessed toward the accommodating cavity 110, forming an annular boss 140 on the inner wall of the housing 100, and defining a roller groove 150 on the outer wall of the housing 100. It is understood that the axis of the annular boss 140 coincides with the axis of the housing 100, and the roller groove 150 is an annular roller groove 150, and the axis of the roller groove 150 coincides with the axis of the annular protrusion.

[0057] It should be noted that there is a gap between the annular boss 140 and the battery cell 200 .

[0058] like Figure 2 As shown, in some embodiments of the present invention, the side of the shell 100 away from the battery cell 200 is folded inward to form a first limiting ring 160, the side of the controller 300 away from the battery cell 200 abuts against the side of the first limiting ring 160 close to the battery cell 200, and the side of the controller 300 close to the battery cell 200 abuts against the side of the annular boss 140 away from the battery cell 200, so as to limit the controller 300 along the axial direction of the battery cell 200 through the annular boss 140 and the first limiting ring 160 to ensure the stability of the connection between the controller 300 and the shell 100.

[0059] like Figure 3 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the controller 300 includes a control board 320 , a support member 330 , an electrode sleeve 340 and an electrode cap 350 .

[0060] The support member 330 is disposed between the electrode cap 350 and the control board 320 to support and secure the electrode cap 350. The connection between the support member 330 and the electrode cap 350 can be achieved by bonding, clamping, threading, or bolting, and can be determined based on practical needs. Furthermore, the connection between the control board 320 and the support member 330 can be achieved by bonding, clamping, or threading.

[0061] In addition, the electrode sleeve 340 is arranged around the edge of the control board 320, that is, the electrode sleeve 340 is arranged around the edge of the control board 320 and forms an electrical connection with the control board 320, and the electrode sleeve 340 is connected to the side wall of the support member 330, so that the support member 330 and the control board 320 are connected through the electrode sleeve 340 to improve the stability of the connection between the support member 330 and the control board 320.

[0062] Specifically, the control plate 320 is provided with an air guide hole 321 , which penetrates the control plate 320 along the thickness direction of the control plate 320 , thereby connecting the air flow channel 310 with the first cavity 130 through the air guide hole 321 .

[0063] In addition, the electrode cap 350 is provided with a second through hole 351. It should be noted that the number of second through holes 351 can be one, two, or more than two, and can be specifically set according to actual conditions. It should be noted that the electrode cap 350 is electrically connected to the control board 320. In this embodiment, the electrode cap 350 is a positive electrode cap, and the housing 100 is a metal conductive housing 100. The electrode cap 350 is connected to the positive electrode of the battery cell 200 through the control board 320, and the negative electrode of the battery cell 200 is connected to the control board 320 through the housing 100.

[0064] In this embodiment, there are two second through holes 351 , and the two second through holes 351 are respectively disposed on two opposite sides of the side wall of the electrode cap 350 , so as to connect the air flow channel 310 with the external space through the second through holes 351 .

[0065] Furthermore, the support member 330 defines a receiving space, and the first through hole 120 , the receiving space, and the air guide hole 321 are connected to form the air flow channel 310 .

[0066] Specifically, the sensor 400 is arranged on the side of the control board 320 facing the battery cell 200, and the sensor 400 covers the end of the air guide hole 321 facing the battery cell 200, so as to detect the air pressure difference between the air flow channel 310 and the first cavity 130 through the sensor 400.

[0067] like Figure 5 As shown, in some embodiments of the present invention, the battery cell 200 includes a body 210 , an adapter plate 220 and an adapter ring 230 .

[0068] The adapter ring 230 is disposed on one side of the main body 210 in the axial direction. The adapter ring 230 and the main body 210 are connected by bonding, welding, or clamping, which can be set according to actual conditions. In this embodiment, the adapter ring 230 and the main body 210 are connected by welding to improve the stability of the connection between the adapter ring 230 and the main body 210.

[0069] Furthermore, the adapter plate 220 is disposed on a side of the adapter ring 230 facing away from the body 210. The adapter plate 220 and the adapter ring 230 may be connected by bonding, welding, or clamping, which can be determined based on actual conditions. In this embodiment, the adapter plate 220 and the adapter ring 230 are connected by welding to enhance the stability of the connection between the adapter ring 230 and the adapter plate 220.

[0070] In some embodiments of the present invention, a plurality of spaced apart limiting holes are provided on the adapter plate 220. It is understood that the number of the limiting holes can be two or more than any number.

[0071] Among them, the inner ring of the adapter ring 230 is provided with a plurality of spaced second limit plates, the number of the second limit plates is equal to the number of the limit holes, and each second limit plate is correspondingly passed through a limit hole, thereby forming a limit structure between the adapter plate 220 and the adapter ring 230 to improve the accuracy and connection efficiency of the connection between the adapter plate 220 and the adapter ring 230.

[0072] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, a plurality of spaced connecting plates 231 are provided on the edge of the adapter ring 230. It should be noted that each connecting plate 231 is parallel to the axis of the housing 100.

[0073] Specifically, the side of the connecting plate 231 facing away from the battery cell 200 abuts against the side of the annular boss 140 close to the battery cell 200, and the adapter ring 230 is electrically connected to the housing 100 through the connecting plate 231, so as to form a limiting structure between the connecting plate 231 and the annular boss 140. The annular boss 140 and the battery cell 200 limit the adapter ring 230 along the axis of the housing 100, thereby ensuring the stability of the adapter ring 230 between the annular boss 140 and the battery cell 200. Because the adapter plate 220 and the battery cell 200 are welded together, that is, the annular boss 140 limits the battery cell 200, preventing the battery cell 200 from shaking in the accommodating cavity 110, thereby ensuring the stability of the battery cell 200 in the accommodating cavity 110.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a first notch 170 is provided on the side wall of the housing 100 . The first notch 170 is close to the opening, and the first notch 170 is communicated with the opening.

[0075] In which, a charging interface 322 is provided on the side of the control board 320 facing away from the battery cell 200, the charging interface 322 is electrically connected to the control board 320, and the charging interface 322 is accommodated in the accommodating space, and the connection end of the charging interface faces the first notch 170, so that an external power interface can be connected to the connection end of the charging interface 322 through the first notch 170.

[0076] like Figure 3 As shown, in some embodiments of the present invention, the electrode sleeve 340 includes an electrode ring 341 and a second limiting ring 342. The second limiting ring 342 is arranged on one side of the axis direction of the electrode ring 341, and the second limiting ring 342 is arranged on the inner edge of the electrode ring 341. Specifically, the electrode ring 341 and the second limiting ring 342 are integrally formed to enhance the overall strength of the electrode sleeve 340, and the axis of the electrode ring 341 coincides with the axis of the second limiting ring 342.

[0077] Specifically, the electrode ring 341 is arranged around the edge of the control board 320, and the second limiting ring 342 is in contact with the side of the control board 320 away from the support member 330, so as to form a limiting effect on the control board 320 through the second limiting ring 342, so as to improve the stability of the connection between the control board 320 and the electrode sleeve 340.

[0078] like Figure 5 As shown, in some embodiments of the present invention, a connector 500 is provided on one side of the control board 320 close to the battery cell 200, and one end of the connector 500 facing away from the control board 320 elastically abuts against the adapter plate 220 to electrically connect the connector 500 to the adapter plate 220, thereby electrically connecting the positive terminal of the battery cell 200 to the control board 320.

[0079] A first conductive portion 600 is provided on a side of the control board 320 facing away from the battery cell 200 . The first conductive portion 600 is connected to the electrode cap 350 , so as to electrically connect the electrode cap 350 to the control board 320 through the first conductive portion 600 .
