[0063] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0065] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0066] See also Figure 1 In a first aspect of the embodiments of the present application, a battery module is provided, which can be used in an atomizer to supply power to electrical components such as an atomizer core in the atomizer.

[0067] Specifically, the battery module provided in this embodiment includes: a battery 10 and a circuit board 20. The battery 10 is electrically connected to one end surface of the circuit board 20. The circuit board 20 serves as an intermediate connection between the battery 10 and other electrical components. For example, the circuit board 20 is arranged above the battery 10, and the battery 10 is connected to the lower end surface of the circuit board 20. Figure 2 As shown, at least two electrode points 25 are provided on the lower end surface of the circuit board 20 , and the circuit board 20 can be electrically connected to the battery 10 through the electrode points 25 .

[0068] See also Figure 3 and Figure 4 , a plurality of electrical connection groups 24 are arranged on the other end surface of the circuit board 20. That is, a plurality of electrical connection groups 24 are arranged on the upper end surface of the circuit board 20. The electrical connection group 24 includes a first contact 21 and a second contact 22; the electrode polarities of the first contact 21 and the second contact 22 are opposite, that is, one of the first contact 21 and the second contact 21 is a positive connection contact, and the other is a negative connection contact.

[0069] In the same electrical connection group 24, the first contact 21 is connected in series with the second contact 22. After the battery module is installed in the shell of the atomizer, the electrical connection group 24 can be connected to the positive connector and the negative connector in the shell of the atomizer, so that the battery 10 can supply power to the electrical components inside the shell.

[0070] In this embodiment, the plurality of electrical connection groups 24 are centrally symmetrically distributed, so that the circuit board 20 can still be connected to the connector in the shell of the atomizer after being flipped at different angles, thereby increasing the angle selection for the battery module to be installed in the shell.

[0071] In this embodiment and the following embodiments, the plurality of electrical connection groups 24 include two or more electrical connection groups 24 .

[0072] For a clearer explanation, see Figure 3 , Figures 5 to 7 The outer shell 40 of the atomizer is provided with an electrode connector 51, wherein the electrode connector 51 may include two and serve as a positive electrode connector and a negative electrode connector respectively. Taking the circuit board 20 provided with two electrical connection groups 24 as an example, Figure 3 The electrical connection group 24 on the left is the first electrical connection group 241, and the electrical connection group 24 on the right is the second electrical connection group 252; Figure 5 The battery 10 is shown on one side as the front side, and the other side is the back side. Figure 5 The x-axis direction is the horizontal direction.

[0073] When the battery module is placed into the outer shell 40 with the battery 10 facing upward, Figure 6 As shown, the second electrical connection group 242 abuts against the electrode connector 51 to achieve electrical connection between the two.

[0074] When the battery module is placed into the outer shell 40 with the battery 10 facing upward, Figure 7 As shown, the first electrical connection group 241 abuts against the electrode connector 51 to achieve electrical connection between the two.

[0075] That is, when the battery module provided in this embodiment is installed into the outer shell 40, it can be installed without distinguishing between the front and back sides, thereby improving the convenience of installing the battery module.

[0076] In the above embodiment in which two electrical connection groups 24 are provided, the battery 10 may be in a rectangular parallelepiped or ellipsoidal shape, and correspondingly, the mounting cavity 41 in the outer shell 40 may be in a rectangular parallelepiped or ellipsoidal shape.

[0077] In another embodiment, see Figure 8The circuit board 20 may be provided with three electrical connection groups 24; correspondingly, the battery 10 and the mounting cavity 41 in the outer shell 40 may be in the shape of a regular triangular prism, so that no matter from which angle the battery 10 is inserted into the mounting cavity 41, at least one electrical connection group 24 may be connected to the electrode connector 51.

[0078] In other embodiments, other numbers of electrical connection groups 24 may be provided on the circuit board 20 , so that the positions of the positive and negative poles of the battery module do not need to be distinguished when the battery module is installed into the installation cavity 41 .

[0079] In practical applications, such as Figure 4 As shown, the multiple electrical connection groups 24 on the circuit board 20 can be independently arranged, specifically so that they are centrally symmetrical, so that after the battery 10 and the circuit board 20 are flipped at a preset angle, one electrical connection group 24 overlaps with another electrical connection group 24.

[0080] In another embodiment provided in this application, please refer to Figure 3 , multiple electrical connection groups 24 can share one first contact 21. Specifically, the multiple electrical connection groups 24 include multiple second contacts 22, and the multiple second contacts 22 are distributed around the first contact 21 in a centrally symmetrical manner.

[0081] In the plurality of electrical connection groups 24 , the plurality of second contacts 22 are connected in parallel to each other, which helps to miniaturize and compact the overall structure of the circuit board 20 .

[0082] In a more specific embodiment, two electrical connection groups 24 are provided on the circuit board 20, that is, a first contact 21 and two second contacts 22 are provided on the circuit board 20, and the two second contacts 22 are symmetrically arranged on both sides of the first contact 21, thereby realizing the central symmetrical arrangement of the two electrical connection groups 24.

[0083] In another embodiment, see Fig. 9 and Fig.10 The battery module further includes: a module housing 30 ; the battery 10 and the circuit board 20 are both disposed in the module housing 30 .

[0084] The module housing 30 can protect the battery 10 and the circuit board 20. In addition, the battery 10 and the circuit board 20 can be integrated into a whole through the module housing 30, and the entire battery module can be replaced when replacement is needed. The upper end surface of the circuit board 20 is exposed outside the module housing 30, which facilitates the connection between the upper end surface of the circuit board 20 and the electrical components in the outer shell 40.

[0085] In practical applications, the battery module and the outer shell 40 can be detachably connected by detachably connecting the module shell 30 and the outer shell 40 .

[0086] In a more specific embodiment, the module housing 30 includes: a bottom cover 31, a shell 32 and an upper cover 33; the bottom cover 31 is connected to one side of the shell 32, for example, it is arranged at the lower side of the shell 32 when it is placed vertically. The upper cover 33 is connected to the other side of the shell 32, for example, it is arranged at the upper side of the shell 32 when it is placed vertically.

[0087] The battery 10 is disposed in the housing 32; the circuit board 20 is disposed on the upper cover 33. Figure 5 The upper cover 33 may be provided with a through hole extending from top to bottom; the circuit board 20 is electrically connected to the battery 10 below through the through hole.

[0088] Furthermore, an insulating layer 34 is provided between the battery 10 and the module housing 30. Specifically, the insulating layer 34 may be in the shape of an insulating sleeve, and after being sleeved on the battery 10, it is installed in the housing 32 together with the battery 10 to achieve insulation separation between the battery 10 and the housing 31.

[0089] For further information, see Fig.11 In the electrical connection group 24 , a short circuit protector 23 is connected between the first contact 21 and the second contact 22 .

[0090] By providing the short-circuit protector 23 , the short-circuit protector 23 can be disconnected when the first contact 21 and the first contact 22 are short-circuited, thereby playing a role of short-circuit protection and preventing the battery 10 from being burned out.

[0091] In application, the short-circuit protector 23 may be a recoverable fuse, an irrecoverable fuse or a diode, etc., so long as it can provide short-circuit protection for the battery module.

[0092] The second aspect of the present application provides an atomizer, see Figure 5 and Fig.12 The atomizer includes: an outer shell 40, a second circuit board 50 and a battery module in any of the above embodiments.

[0093] An installation cavity 41 is provided in the outer shell 40; the second circuit board 50 and the battery module are both provided in the installation cavity 41; the battery module and the outer shell 40 are detachably connected; an electrode connector 51 is provided on the second circuit board 50; the electrode connector 51 is electrically connected to any electrical connection group 24 in the battery module.

[0094] In this embodiment, the multiple electrical connection groups 24 in the battery module are centrally symmetrically distributed, and the center line of the centrally symmetrical distribution of the multiple electrical connection groups 24 is the center line of the installation cavity 41, so that after the battery module is flipped at a preset angle, there is always an electrical connection group 24 that can be aligned with the electrode connector 51, so as to realize multi-angle installation of the battery module. Among them, the preset angle can correspond to the shape of the installation cavity 41 and the shape of the battery 10; for example, when the battery 10 and the installation cavity 41 are in the shape of a rectangular column, two electrical connection groups 24 can be provided on the circuit board 20, and the two electrical connection groups 24 are symmetrically arranged, so that there is no need to distinguish the front and back sides when the battery module is installed in the outer shell 40.

[0095] It should be noted that after the second circuit board 50 is installed in the installation cavity 41, the position of the electrode connector 51 corresponds to the position of any electrical connection group 24 after the battery module is installed in the installation cavity 41, ensuring that the battery module can be docked with the electrode connector 51 after installation.

[0096] In a more specific embodiment, the battery module includes: a module housing 30 ; the module housing 30 is installed in the installation cavity 41 and is detachably connected to the outer housing 40 .

[0097] That is, in the present embodiment, the battery module is detachably connected to the outer shell 40 through its module shell 30, and specifically can be detachably connected to the outer shell 40 through the bottom cover 31 of the module shell 30; wherein, after the battery module is inserted into the installation cavity 41, the bottom cover 31 can close the installation cavity 41; and the bottom cover 31 can be connected to the outer shell 40 by a snap-on connection.

[0098] Correspondingly, after the battery module is connected to the outer shell 40, the bottom cover 31 can be exposed outside the outer shell 40, and the bottom cover 31 can be provided with friction patterns for the user to move the bottom cover 31, so that when the battery module needs to be replaced, the entire battery module can be taken out by moving the bottom cover 31.

[0099] In actual applications, the battery module can be installed by being completely loaded into the installation cavity 41. Specifically, a flippable cover can be provided outside the outer shell 40. The position of the cover corresponds to the position of the installation cavity 41, so that the opening and closing of the installation cavity 41 can be controlled by flipping the cover. When the battery module needs to be replaced, the installation cavity 41 can be opened by flipping the cover, and then the battery module can be taken out of the installation cavity 41. In addition, after the battery module is installed, when the cover is closed, the cover can abut against the battery module, so that the battery module is fixed and pressed in the installation cavity 41.

[0100] The third aspect of the present application provides an atomizer, see Fig.13 The atomizer includes: a shell 1, a circuit board 2 and a battery module 3.

[0101] An installation cavity 101 is provided inside the shell 1; the circuit board 2 is provided in the installation cavity 101; a plurality of electrical connection groups 200 are provided on the end surface of the circuit board 2 which opens toward the installation cavity 101; the plurality of electrical connection groups 200 are distributed symmetrically with respect to the center; the battery module 3 is provided in the installation cavity 101 and is detachably connected to the shell 1; the battery module 3 is electrically connected to any electrical connection group 200.

[0102] In this embodiment, the battery module 3 is provided with an electrical connector electrically connected to the electrical connection group 200. Also, taking the case where two electrical connection groups 200 are included as an example, the battery module 3 can be electrically connected to one electrical connection group 200 regardless of whether the front side or the back side is facing upward.

[0103] As a further improvement, the multiple electrical connection groups 200 in this embodiment can also adopt a shared contact method; specifically, the multiple electrical connection groups 200 include a first contact 201 and multiple second contacts 202; the electrode polarities of the first contact 201 and the second contact 202 are opposite; the multiple second contacts 202 are distributed symmetrically around the first contact 201.

[0104] Each second contact 202 is connected in series with the first contact 201 , and different second contacts 202 are connected in parallel with each other.

[0105] In other embodiments, each electrical connection group 200 may also be independently configured.

[0106] In one embodiment, further, a base 4 is connected to a side of the battery module 3 away from the circuit board 2 ; the battery module 3 is detachably connected to the housing 1 via the base 4 .

[0107] Correspondingly, a slot for the battery module 3 to be inserted into may be provided on the base 4; after the battery module 3 is installed in the installation cavity 41, the base 4 is engaged with the shell 1, thereby realizing a detachable connection between the battery module 3 and the shell 1.

[0108] Compared with the above embodiment, the circuit board 2 with multiple electrical connection groups 200 in this embodiment is arranged in the housing 1, and the problem of multi-angle installation of the battery module 3 can also be solved; the difference is that, for example, in the case where a non-recoverable fuse is arranged between the first contact 201 and the second contact 202, it is difficult to replace the circuit board 2 when a circuit board 2 fails. That is, in the battery module and the atomizer provided in the first and second aspects of the present application, the circuit board 20 is arranged on the battery module, so that when the circuit board 20 fails, it can be replaced together with the entire battery module.

[0109] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
