[0029] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0031] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] Please refer to Figure 1-7 In an embodiment of the present application, an atomization device is provided, which can be used to heat an aerosol matrix to form an aerosol and discharge it; wherein the atomization device mainly includes a housing (not shown in the figure), an atomization component 6 and a power supply device 1.

[0033] The housing is formed at the outermost side of the atomizing device, and the user can grasp the atomizing device by holding it. The housing may also have a touch button for operating the atomizing device, a display screen for displaying the working state of the atomizing device, and an observation window for observing the amount of aerosol matrix used in the atomizing device. In order to facilitate the user's holding, an anti-slip part may be provided on the surface of the housing, and the anti-slip part may be a structural part such as an anti-slip pattern, an anti-slip groove, an anti-slip convex point, etc., and a material with a high friction coefficient may also be used as at least a part of the housing.

[0034] The atomizing assembly 6 is used to heat the aerosol matrix to generate an aerosol. The aerosol matrix can be in a solid or liquid state. When the atomizing assembly 6 is powered on, it will generate heat. When acting on the aerosol matrix, the aerosol matrix is ​​atomized and mixed with air to form an aerosol, which can finally be discharged from the housing.

[0035] In order to accommodate various components including the atomization component 6 and the aerosol matrix, a liquid storage chamber 24 and an atomization channel 25 are formed inside the supporting component 2 of the power supply device 1. The atomization component 6 is arranged in the atomization channel 25, and the aerosol matrix is ​​arranged in the liquid storage chamber 24; the liquid storage chamber 24 is directly or indirectly connected to the atomization component 6, so that the aerosol matrix can enter the atomization component 6, so that the atomization component 6 can heat the aerosol matrix and discharge it after generating aerosol.

[0036] In order to supply power to various components in the atomization device, a power supply device 1 is provided in the embodiment of the present application, and the power supply device 1 is arranged in the housing. The components of the power supply device 1 at least include a carrier assembly 2, a battery assembly 3 and a circuit board assembly 4, wherein the circuit board assembly 4 and the battery assembly 3 are arranged on the same side of the carrier assembly 2.

[0037] The carrier component 2 and the circuit board component 4 are arranged relative to each other in a first direction X, wherein the first direction X represents the connection direction between the carrier component 2 and the circuit board component 4. Figure 1-4As shown. The carrier assembly 2 and the circuit board assembly 4 are fixedly connected, wherein the carrier assembly 2 and the circuit board assembly 4 can be fixedly connected by means of snaps, threaded fasteners, etc. The circuit board assembly 4 and the battery cell assembly 3 are arranged on the same side of the carrier assembly 2, indicating that the positions of the circuit board assembly 4 and the battery cell assembly 3 are close to each other; wherein the circuit board assembly 4 and the carrier assembly 2 can be fixedly connected directly or indirectly.

[0038] The battery cell assembly 3 is arranged on the carrier assembly 2, in order to realize that the electric energy in the battery cell assembly 3 is provided to other components in the atomization device that need to be powered, such as the atomization assembly 6. Figure 3 and Figure 4 As shown, the battery cell assembly 3 has a battery cell tab 31 and a battery cell cable 32 arranged near one side of the circuit board assembly 4 in the first direction X, and the battery cell cable 32 is connected to the battery cell tab 31. Among them, the battery cell assembly 3 is fixedly arranged on the carrier assembly 2, so among the components of the battery cell assembly 3, the battery cell tab 31 and the battery cell cable 32 are arranged near one side of the circuit board assembly 4, wherein the battery cell cable 32 is responsible for transmitting the electric energy possessed by the battery body 33 in the battery cell assembly 3 to other components including the atomization assembly 6. The battery cell cable 32 can be directly or indirectly connected to the component to be powered, for example, the battery cell cable 32 can be connected to the circuit board assembly 4, and then the circuit board assembly transmits the electric energy to other components respectively.

[0039] An electrical connector 41 is fixedly provided on the circuit board assembly 4, and the electrical connector 41 is arranged facing the battery cell assembly 3 in the first direction X, wherein the electrical connector 41 is used to be plugged into the interface on the housing to transmit signals and realize the corresponding functions of the atomization device. Among them, the electrical connector 41 represents a connector with an exposed conductive surface, and the specific form can be a pin needle group, a plug, etc. Since the electrical connector 41 has an exposed and conductive surface, it is necessary to avoid direct contact between the electrical connector 41 and the battery cell tab 31 or the battery cell cable 32. Among them, the electrical connector 41 extends away from the liquid storage chamber 24, that is, the free end of the electrical connector 41 is away from the liquid storage chamber 24 to connect with other interfaces.

[0040] Since the cell tabs 31 and the cell cables 32 are arranged on the side close to the circuit board assembly 4 on the cell assembly 3, and the circuit board assembly 4 has an electrical connector 41 arranged close to the cell assembly 3, the spacing between the cell tabs 31 and the cell cables 32 and the electrical connector 41 is relatively small. The cell tabs 31, the cell cables 32 and the electrical connector 41 all have conductive properties. In order to prevent the electrical connector 41 from affecting the cell tabs 31 and the cell cables 32, the carrier assembly 2 has an isolation structure 5, which blocks the electrical connector 41 and the cell assembly 3, and is used to isolate the cell tabs 31 and the cell cables 32 from the electrical connector respectively. The isolation structure 5 itself is made of insulating material. The isolation structure 5 is set between the electrical connector 41 and the battery cell assembly 3. On the one hand, it can prevent the electrical connector 41 from directly contacting the battery cell tab 31, resulting in a direct short circuit of the battery cell tab 31; on the other hand, it can prevent the electrical connector 41 from contacting the battery cell cable 32, preventing the battery cell cable 32 from passing through the electrical connector 41 and causing a short circuit of the battery cell cable 32, thereby reducing the power supply risk of the battery cell assembly 3 and improving the power supply reliability of the battery cell assembly 3.

[0041] The isolation structure 5 is arranged on the supporting component 2, wherein the isolation structure 5 can be directly integrally formed with the supporting component 2 body through a process such as injection molding, or the isolation structure 5 can also be fixedly connected with the supporting component 2 body through adhesive, snap fasteners, etc.

[0042] For some optional embodiments, please continue to refer to Figure 3 and Figure 4 In order to achieve a good effect of isolating the battery cell assembly 3 and the electrical connector 41, the isolation structure 5 may specifically include a first isolation plate 51, which is accommodated between the battery cell assembly 3 and the circuit board assembly 4 in the first direction X, and the first isolation plate 51 has a preset length in the second direction Y, and the first direction X intersects with the second direction Y. The isolation structure 5 may be a plate-shaped first isolation plate 51, and the isolation effect between the battery cell assembly 3 and the electrical connector 41 can be achieved by setting the size of the first isolation plate 51. Among them, since the first isolation plate 51 has a preset length in the second direction Y, and the second direction Y intersects with the first direction X, the first isolation plate 51 is arranged between the battery cell assembly 3 and the electrical connector 41, and the contact between the battery cell tab 31 and the battery cell cable 32 in the battery cell assembly 3 and the electrical connector 41 is eliminated from the structural level. The second direction Y intersects with the first direction X, indicating that the second direction Y and the first direction X form an angle that is not zero. In the extreme case, the second direction Y and the first direction X are perpendicular to each other. According to the different angles between the first direction X and the second direction Y, the preset length of the first isolation plate 51 in the second direction Y can be set accordingly to ensure the isolation between the battery core assembly 3 and the electrical connector 41 .

[0043] In some optional embodiments, in order to further enhance the insulation isolation effect of the isolation structure 5 on the electrical connector 41 and the battery cell assembly 3, the isolation structure 5 may further include a second isolation plate 52 and a third isolation plate 53, wherein the second isolation plate 52 is disposed on one side of the first isolation plate 51 in the third direction Z, and the third isolation plate 53 is disposed on the other side of the first isolation plate 51 in the third direction Z, and the first isolation plate 51, the second isolation plate 52 and the third isolation plate 53 enclose an isolation space that accommodates at least part of the structure of the electrical connector 41, and the battery cell cable 32 is located outside the isolation space; the first direction X, the second direction Y and the third direction Z are perpendicular to each other. The second isolation plate 52 and the third isolation plate 53 are respectively disposed at the two ends of the first isolation plate 51, and the first isolation plate 51, the second isolation plate 52 and the third isolation plate 53 directly enclose an isolation space that accommodates at least part of the structure of the electrical connector 41, and the battery cell cable 32 is routed outside the isolation space, thereby preventing the battery cell cable from passing through the isolation space and contacting the electrical connector 41. Therefore, the specific extension direction of the second isolation plate 52 and the third isolation plate 53 can be set according to the layout of the electrical connector 41. For example, if the electrical connector 41 is rectangular as a whole, the second isolation plate 52 and the third isolation plate 53 can be extended along the first direction X, away from the position where the battery core assembly 3 is located, so that the first isolation plate 51, the second isolation plate 52 and the third isolation plate 53 enclose a semi-enclosed rectangle. If the electrical connector 41 is trapezoidal as a whole, the corresponding second isolation plate 52 and the third isolation plate 53 can be extended obliquely, so that the first isolation plate 51, the second isolation plate 52 and the third isolation plate 53 enclose a semi-enclosed trapezoid. Electrical connectors 41 of other shapes can be set accordingly, and they are not limited in the embodiments of the present application. The first direction X, the second direction Y and the third direction Z are perpendicular to each other, as shown in the figure.

[0044] For some optional embodiments, please continue to refer to Figure 1 and Figure 2 In order to allow the electrical connector 41 to extend freely from the circuit board assembly 4, a guide channel 50 is formed between the circuit board assembly 4 and the isolation structure 5, the electrical connector 41 is arranged in the guide channel 50, and the free end of the electrical connector 41 extends out of the guide channel 50. The electrical connector 41 includes a fixed end fixed to the circuit board assembly 4, and the portion used to be plugged into the interface on the housing is the free end. The free end needs to be configured to be exposed to the isolation structure 5, so that the free end can extend out of the guide channel 50, to avoid the guide channel 50 abutting against the interface so that the electrical connector 41, i.e., the pin, cannot be plugged into the interface. Among them, the guide channel 50 can be formed by the enclosure between the isolation structure 5 and the circuit board assembly 4, so that the electrical connector 41 has a relatively closed enclosure structure, so that the electrical connector 41 can be better isolated from the battery core assembly 3.

[0045] For some optional embodiments, please continue to refer to Figure 1 and Figure 2 In order to facilitate the plugging of the electrical connector 41 into the female socket on the housing, improve the assembly reliability of the electrical connector 41, and avoid the isolation structure 5 itself limiting the plugging space of the electrical connector 41, the free end of the electrical connector 41 can extend out of the guide channel 50 along the second direction Y. When the free end of the electrical connector 41 extends out of the guide channel 50, the electrical connector 41 can extend out of the guide channel 50 along the height direction after the guide channel 50 is enclosed, wherein the height direction after the guide channel 50 is enclosed is equivalent to the second direction Y, and the second direction Y is perpendicular to the first direction X. In other words, it is equivalent to the size of the isolation structure 5 in the second direction Y, which is smaller than the extension length of the electrical connector 41 in this direction, so as to avoid the isolation structure 5 from hitting the PCB board docked with the electrical connector 41, and further avoid the electrical connector 41 from being improperly plugged in. In addition, in order to prevent the electrical connector 41 from extending too long, resulting in too much exposed portion of the electrical connector 41, which affects the isolation effect between the electrical connector 41 and the battery cell assembly 3, the extension length of the electrical connector 41 extending out of the guide channel 50 along the second direction Y is less than or equal to the length of the guide channel 50 in the second direction Y, that is, at least half of the length of the electrical connector 41 is located within the enclosed range of the guide channel 50, so as to achieve the isolation effect between the electrical connector 41 and the battery cell assembly 3 while ensuring that the electrical connector 41 is normally plugged into the interface. Based on the above-mentioned dimensional conditions, in the embodiment of the present application, the total extension length of the guide channel 50 in the second direction Y is greater than or equal to half of the extension length of the electrical connector 41 in the second direction Y, and less than the extension length of the electrical connector 41 in the second direction Y.

[0046] For some optional embodiments, please refer to Figure 5-7 In order to assemble and fix the battery cell assembly 3, the surface of the carrier assembly 2 may be provided with an installation groove 21, and the installation groove 21 is used to fix the battery cell body 33 of the battery cell assembly 3. The battery cell tabs 31 and the battery cell cable 32 in the battery cell assembly 3 are not made of hard materials, and they need to adjust their positions according to the specific internal design of the atomization device. Therefore, the battery cell assembly 3 is generally fixed based on the fixation of the battery cell body 33. Among them, the battery cell body 33 can be fixed in the installation groove 21 by means of clamping, gluing, etc., to avoid shaking of the battery cell body 33 during use.

[0047] In some optional embodiments, in order to stabilize the battery cell assembly 3, the surface of the carrier assembly 2 has a limiter 23 and a supporter 22 arranged relatively in the first direction X, and a mounting groove 21 is formed between the limiter 23, the supporter 22 and the surface of the carrier assembly 2, and the battery cell body 33 is fixedly arranged in the mounting groove 21. Among them, the limiter 23 is arranged at an end away from the circuit board assembly 4 along the first direction X, and the supporter 22 is arranged at an end close to the circuit board assembly 4 along the first direction X. In addition, the supporter 22 is arranged relatively to the battery cell tab 31, so that the supporter 22 can prevent the battery cell body 33 from moving toward the side of the circuit board assembly 4 along the first direction X, thereby preventing the battery cell tab 31 from being squeezed.

[0048] In some optional embodiments, in order to further improve the isolation effect between the cell tab 31 and the electrical connector 41, the cell assembly 3 may further include an insulating coating layer, which is wrapped around the cell tab 31. The insulating coating layer may be high temperature glue, EVA cotton, etc.

[0049] An atomization device and a power supply device 1 thereof are provided in the embodiment of the present application. In the power supply device 1, an isolation structure 5 is provided between the battery cell assembly 3 and the electrical connector 41. The isolation structure 5 isolates the battery cell tab 31 and the battery cell cable 32 from the electrical connector 41, thereby effectively avoiding direct contact between the battery cell tab 31 and the electrical connector 41, and between the battery cell cable 32 and the electrical connector 41, further reducing the possibility of short circuit of the battery cell assembly 3, thereby improving the safety performance of the atomization device.

[0050] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
