[0053] An electronic atomizer is a device that heats an atomizing liquid to atomize it into an aerosol. The aerosol formed by the atomization of the atomizing liquid can be used for inhalation by the user.

[0054] An electronic atomizer generally includes an atomizing device and a power supply device. The power supply device is used to supply power to the atomizing device. The atomizing device is used to heat the atomizing liquid so that the atomizing liquid can be atomized to form an aerosol.

[0055] In some cases, the power supply device may include components such as batteries and circuit board assemblies. There are many components and they are difficult to arrange reasonably, which makes the power supply device larger in size, resulting in a larger size of the electronic vaporizer, which is not conducive to the portable use of the electronic vaporizer.

[0056] Based on this, the embodiments of the present application provide a power supply device and an electronic atomizer, which can improve the problem of the large size of the power supply device of the electronic atomizer.

[0057] Please also refer to Figures 1 to 5 ,in, Figure 1 The three-dimensional structure diagram of the electronic atomizer 100 provided in some embodiments of the present application, Figure 2 The three-dimensional structure of the power supply device 10 provided in some embodiments of the present application Figure 1 , Figure 3for Figure 2 Exploded diagram of Figure 4 for Figure 2 A three-dimensional structural diagram of the circuit board assembly 13, the charging interface 15, the unlocking switch 17 and the lamp bead 134 of the power supply device 10 is provided. Figure 5 2 is a cross-sectional view along AA. The power supply device 10 provided in an embodiment of the present application includes a housing assembly 11, a battery 12 and a circuit board assembly 13. The battery 12 is arranged in the housing assembly 11. The circuit board assembly 13 includes a first circuit board 131, a second circuit board 132 and a third circuit board 133. The second circuit board 132 and the third circuit board 133 are arranged on the first circuit board 131 at intervals along the first direction Y, and are both electrically connected to the first circuit board 131. The first circuit board 131 is arranged on one side of the battery 12 along the second direction Z and is electrically connected to the battery 12. The second circuit board 132 and the third circuit board 133 are respectively arranged at opposite ends of the battery 12 along the first direction Y. The first direction Y is perpendicular to the second direction Z.

[0058] The circuit board assembly 13 is composed of multiple circuit boards and is primarily used to control the battery 12 to power the atomizer 20 and control the operation of the atomizer 20. For example, the circuit board assembly 13 can control the atomizer 20 to start or stop, change the atomization mode of the atomizer 20, and so on. The multiple circuit boards of the circuit board assembly 13 may include at least a first circuit board 131, a second circuit board 132, and a third circuit board 133. The first circuit board 131, the second circuit board 132, and the third circuit board 133 are used to coordinate the operation of the atomizer 20. The circuit boards of the circuit board assembly 13 can be flexible circuit boards, rigid circuit boards, etc.

[0059] The battery 12 and the circuit board assembly 13 are both disposed within the housing assembly 11, so that the housing assembly 11 can provide protection for the battery 12 and the circuit board assembly 13. It is understood that the first circuit board 131, the second circuit board 132, and the third circuit board 133 of the circuit board assembly 13 are all disposed within the housing assembly 11.

[0060] When the atomizing device 20 is assembled on the housing assembly 11, the first circuit board 131 of the circuit board assembly 13 can be directly or indirectly connected to the atomizing device 20; or the second circuit board 132 can be directly or indirectly connected to the atomizing device 20; or the third circuit board 133 can be directly or indirectly connected to the atomizing device 20. As an example, Figure 5 As shown, the second circuit board 132 is indirectly connected to the atomization device 20 via the conductive member 14 mentioned below.

[0061] The first direction Y is the approximate distribution direction of the second circuit board 132 and the third circuit board 133 . The first direction Y may be perpendicular or non-perpendicular to the second circuit board 132 , the first direction Y may be perpendicular or non-perpendicular to the third circuit board 133 , and the first direction Y may be parallel or non-parallel to the first circuit board 131 .

[0062] For the convenience of description, the electronic atomizer 100 may further have a third direction X, where the third direction X is perpendicular to the first direction Y and the third direction X is perpendicular to the second direction Z.

[0063] The first direction Y is perpendicular to the second direction Z, the first direction Y is perpendicular to the third direction X, and the second direction Z is perpendicular to the third direction X, which means that the two directions are approximately perpendicular, and a certain deviation is allowed.

[0064] The first direction Y, the second direction Z and the third direction X may all be double-arrow directions.

[0065] In some cases, the first direction Y may be a length direction of the electronic atomizer 100 , the second direction Z may be a thickness direction of the electronic atomizer 100 , and the third direction X may be a width direction of the electronic atomizer 100 .

[0066] Specifically, in the first direction Y, the second circuit board 132 is disposed in the housing assembly 11 and at one end of the battery 12 . In the first direction Y, the third circuit board 133 is disposed in the housing assembly 11 and at the other end of the battery 12 .

[0067] The power supply device 10 provided in the embodiment of the present application includes a first circuit board 131, a second circuit board 132, and a third circuit board 133 through a circuit board assembly 13. The first circuit board 131 is provided on one side of the battery 12 along the second direction Z, and the second circuit board 132 and the third circuit board 133 are provided on the first circuit board 131 at intervals along the first direction Y, and are respectively provided at opposite ends of the battery 12, so that the circuit board assembly 13 can be divided into multiple circuit boards, and are respectively arranged on the outside of the battery 12. In this way, the circuit board assembly 13 and the battery 12 can be arranged more compactly, and it is also convenient to improve the compactness between the circuit board assembly 13 and the housing assembly 11. In this way, it helps to improve the rationality and compactness of the layout of the components inside the power supply device 10, thereby helping to reduce the volume of the power supply device 10, thereby reducing the volume of the electronic atomizer 100, and improving the portability of the electronic atomizer 100.

[0068] Furthermore, by providing a second circuit board 132 and a third circuit board 133 spaced apart on the first circuit board 131, the conductive member 14 described below can be arranged on the second circuit board 132, and the charging port 15 and the unlocking switch 17 described below can be arranged on the third circuit board 133. This saves on the arrangement of cables within the housing assembly 11, making the components within the housing assembly 11 very simple, eliminating the need to reserve a large space within the housing assembly 11 for arranging cables, and thus reducing the volume of the housing assembly 11, thereby helping to reduce the volume of the electronic atomizer 100.

[0069] In some embodiments, please refer to Figures 4 to 8 , and combined with other drawings. Among them, Figure 6 for Figure 2 An exploded view of the housing assembly 111 of the power supply device 10 is provided. Figure 7 for Figure 6 The enlarged view of point B in the middle. Figure 8 for Figure 6 Enlarged view of point C in the middle. A first slot 1101 and a second slot 1102 are defined within the housing assembly 11. The first slot 1101 and the second slot 1102 are located at opposite ends of the battery 12 along the first direction Y. The first circuit board 131 is inserted into the first slot 1101 along the second direction Z, and the second circuit board 132 is inserted into the second slot 1102 along the second direction Z.

[0070] The first slot 1101 is a slot for inserting the second circuit board 132 along the second direction Z, and the second slot 1102 is a slot for inserting the third circuit board 133 along the second direction Z.

[0071] Specifically, in the second direction Z, at least one end of the first slot 1101 and the second slot 1102 has an opening, so that the second circuit board 132 can be inserted into the first slot 1101 along the second direction Z from the opening of the first slot 1101, and the third circuit board 133 can be inserted into the second slot 1102 along the second direction Z from the opening of the second slot 1102.

[0072] By adopting the above technical solution, the circuit board assembly 13 can be arranged along the second direction Z. The first circuit board 131 of the circuit board assembly 13 can be arranged on one side of the battery 12 along the second direction Z. The second circuit board 132 can be inserted into the first slot 1101 along the second direction Z. The third circuit board 133 can be inserted into the second slot 1102 along the second direction Z. This arrangement allows the first slot 1101 and the second slot 1102 to respectively position the second circuit board 132 and the third circuit board 133, facilitating assembly of the circuit board assembly 13 within the housing assembly 11.

[0073] In some embodiments, see Figure 7 , and in combination with other drawings, the second circuit board 132 is limitedly located in the first slot 1101 along the first direction Y.

[0074] In some embodiments, the second circuit board 132 may also be located within the first slot 1101 along the third direction X. Figure 6 and Figure 7 As shown, the first slots 1101 are provided in plurality, and the plurality of first slots 1101 are distributed at intervals along the third direction X, and the plurality of first slots 1101 are used to cooperate to limit the second circuit board 132 in the third direction X.

[0075] In some embodiments, see Figure 8 , and in combination with other drawings, the third circuit board 133 is located in the second slot 1102 along the first direction Y.

[0076] In some embodiments, the third circuit board 133 may also be located within the second slot 1102 along the third direction X. Figure 6 and Figure 8 As shown, the second slots 1102 are provided in plurality, and the plurality of second slots 1102 are distributed at intervals along the third direction X, and the plurality of second slots 1102 are used to cooperate to limit the third circuit board 133 in the third direction X.

[0077] As described above, the circuit board assembly 13 can be limited to ensure the assembly effect of the circuit board assembly 13 in the housing assembly 11.

[0078] In some embodiments, see Figure 4 The second circuit board 132 and the third circuit board 133 are both disposed on one side of the first circuit board 131 along the second direction Z, and the second circuit board 132 and the third circuit board 133 are both disposed between opposite ends of the first circuit board 131 along the first direction Y.

[0079] Specifically, the second circuit board 132 and the third circuit board 133 are both arranged on a side of the first circuit board 131 close to the battery 12 along the second direction Z. In this way, the size of the housing assembly 11 in the second direction Z can be reduced, thereby helping to reduce the volume of the housing assembly 11.

[0080] By arranging the second circuit board 132 and the third circuit board 133 between the opposite ends of the first circuit board 131 along the first direction Y, the second circuit board 132 and the third circuit board 133 can be very close to the battery 12 along the second direction Z. In the first direction Y, the space between the corresponding ends of the second circuit board 132 and the first circuit board 131, and the space between the corresponding ends of the third circuit board 133 and the first circuit board 131 can be used to accommodate required components. This can improve the space utilization of the housing assembly 11 in the first direction Y, help reduce the size of the housing assembly 11 in the first direction Y, and thus help reduce the volume of the housing assembly 11.

[0081] In addition, when the first circuit board 131 is disposed on one side of the battery 12 along the second direction Z, the side of the first circuit board 131 close to the battery 12 along the second direction Z can be overlapped on the housing assembly 11.

[0082] In some embodiments, please refer to Figures 2 to 5 、 Figure 9 , and combined with other drawings. Among them, Figure 9 The three-dimensional structure of the power supply device 10 provided in some embodiments of the present application Figure 2 The power supply device 10 further includes a conductive member 14 , which is disposed on the second circuit board 132 and electrically connected to the second circuit board 132 . The conductive member 14 is exposed at one end of the housing assembly 11 along the first direction Y and is used to connect and conduct with the atomization device 20 .

[0083] The conductive member 14 is a component used to connect and conduct with the atomizing device 20 so that the circuit board assembly 13 can control the operation of the atomizing device 20. The conductive member 14 can be, but is not limited to, a spring pin.

[0084] By directly setting the conductive member 14 on the second circuit board 132 and electrically connecting it to the second circuit board 132 , the conductive relationship between the conductive member 14 and the circuit board assembly 13 is very simple, which can save cables between the conductive member 14 and the circuit board assembly 13 and help reduce the volume of the housing assembly 11 .

[0085] It can be understood that in the first direction Y, the housing assembly 11 has one end of the conductive member 14 for assembling the atomizing device 20 . When the atomizing device 20 is assembled to the housing assembly 11 , the conductive member 14 and the atomizing device 20 are connected and conducted.

[0086] In some embodiments, please refer to Figures 2 to 6 , and in conjunction with other figures. The power supply device 10 also includes a charging port 15. The charging port 15 is disposed on and electrically connected to the third circuit board 133. The charging port 15 is exposed at one end of the housing assembly 11 away from the conductive member 14 along the first direction Y and is used to charge the battery 12.

[0087] The charging interface 15 is an interface for connecting to an external cable to charge the battery 12. The charging interface 15 can be of Type-A, Type-B, Type-C, etc.

[0088] The charging interface 15 is directly provided on the third circuit board 133 and electrically connected to the third circuit board 133, so that the conductive relationship between the charging interface 15 and the circuit board assembly 13 is very simple, which can save the cable between the charging interface 15 and the circuit board assembly 13 and help reduce the volume of the housing assembly 11.

[0089] Furthermore, the charging port 15 and the conductive member 14 are respectively disposed at opposite ends of the housing assembly 11 along the first direction Y, so that the components within the housing assembly 11 can be reasonably arranged, thereby reducing the volume of the housing assembly 11 .

[0090] In some embodiments, please refer to Figures 2 to 4 The power supply device 10 further includes a touch screen 16 . The touch screen 16 is disposed on a side of the first circuit board 131 away from the battery 12 and is electrically connected to the first circuit board 131 .

[0091] The touch screen 16 is also called a "touch screen" or "touch panel". It is an inductive liquid crystal display device that can receive input signals such as a contact. The touch screen 16 can be, but is not limited to, an infrared touch screen, a capacitive touch screen, etc.

[0092] By adopting the above technical solution, the user can operate the touch screen 16, and the circuit board assembly 13 receives the signal from the touch screen 16 and controls the atomization device 20 to start, shut down, change the atomization mode, and other operations. For example, when the user operates the touch screen 16, the circuit board assembly 13 can receive the signal from the touch screen 16 and control the battery 12 to power the atomization device 20, so that the atomization device 20 starts and performs atomization. Among them, the atomization mode of the atomization device 20 can include different atomization amounts, different atomization times, and other modes. This configuration makes the operation of the electronic atomizer 100 very intelligent and convenient.

[0093] In some embodiments, please refer to Figures 2 to 4 The power supply device 10 further includes an unlocking switch 17 . The unlocking switch 17 is disposed on the third circuit board 133 and electrically connected to the third circuit board 133 , and is used to lock or unlock the touch screen 16 .

[0094] Unlock switch 17 is a switch structure that can be operated by the user. By operating unlock switch 17, the user can lock or unlock touch screen 16. Specifically, when the user operates unlock switch 17, circuit board assembly 13 can receive a signal from unlock switch 17, thereby controlling whether touch screen 16 is locked or unlocked. Unlock switch 17 can be a push-button switch, a touch switch, a push switch, or other switch structures.

[0095] When the touch screen 16 is unlocked, the user can operate the touch screen 16 to control the atomizing device 20. When the touch screen 16 is locked, the user cannot operate the touch screen 16.

[0096] In this way, the touch screen 16 can be locked by operating the unlock switch 17, so that the touch screen 16 cannot be touched. In this way, the problem of accidental touch of the touch screen 16 can be improved, thereby improving the user experience of the electronic atomizer 100.

[0097] By directly setting the unlocking switch 17 on the third circuit board 133 and electrically connecting it to the third circuit board 133, the conduction relationship between the unlocking switch 17 and the circuit board assembly 13 is very simple, which can save the cable between the unlocking switch 17 and the circuit board assembly 13 and help reduce the volume of the housing assembly 11.
