[0033] An embodiment of the utility model provides a power supply unit and an electronic atomization device, wherein the electronic atomization device includes a power supply unit. The power supply unit is used to provide electrical energy to the electronic atomization device so that the atomization medium in the atomization unit can be heated to form an aerosol for inhalation by a user.

[0034] The following uses an electronic cigarette as an electronic atomization device as an example to illustrate the structure of the power supply unit in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the power supply unit of the present application is not limited to electronic cigarettes, but can also be used in any other type of electronic atomization device, or in other small electronic products, which is not limited here.

[0035] See also Figure 1 , Figure 1 and Figure 2 An exploded schematic diagram of a partial structure of an electronic atomization device 10 in an embodiment of the present application is shown. The electronic atomization device 10 provided in an embodiment of the present application includes a housing 100, an atomization unit (not shown in the figure) and a power supply unit 200. The atomization unit and the power supply unit 200 are arranged in the housing 100. The atomization unit is connected to the power supply unit 200 and is arranged at the upper end of the power supply unit 200 along the X direction in the figure, wherein the atomization unit can be connected to the power supply unit 200 by a snap, or connected to the power supply unit 200 by a magnet. The power supply unit 200 is used to provide electrical energy to the atomization unit, and the atomization unit is used to store the atomization medium, and heat and atomize the atomization medium to generate an aerosol for the user to inhale.

[0036] Specifically, in one embodiment, Figures 1 to 3 As shown, the power supply unit 200 includes a bracket 210, a battery cell 220, a circuit board 230, a first contact assembly 240, a second contact assembly 250 and a bracket cover 260, wherein the bracket 210 is used to fix the battery cell 220 and the circuit board 230, and has a first mounting position 211 and a second mounting position 212 isolated from each other in a Y direction perpendicular to the X direction, the first mounting position 211 has an opening at the top end in the X direction, the battery cell 220 is arranged in the first mounting position 211, and the circuit board 230 is arranged in the second mounting position 2 12, the first contact assembly 240 and the second contact assembly 250 are respectively connected to the circuit board 230, the first contact assembly 240 is arranged at the bottom of the first installation position 211 and abuts against the bottom end of the battery cell 220, the second contact assembly 250 is arranged at the top of the first installation position 211 and adhered to the top end of the battery cell 220, and the bracket cover 260 is detachably arranged on the bracket 210 by screw connection or by snap-fit ​​fixing, and abuts against the second contact assembly 250 and closes the opening of the first installation position 211. One end of the circuit board 230 has two or three contact electrodes 231, each of which is penetrated by the bracket cover 260 and protrudes from the side surface of the bracket cover 260 away from the bracket 210. When the atomizer unit is installed in the housing 100, the atomizer unit can abut against the contact electrode 231, so that the atomizer unit can be electrically connected to the power supply unit 200.

[0037] It can be understood that the first contact component 240 is connected to the positive electrode of the battery cell 220, and the second contact component 250 is connected to the negative electrode of the battery cell 220, or the first contact component 240 is connected to the negative electrode of the battery cell 220, and the second contact component 250 is connected to the positive electrode of the battery cell 220. In this way, the circuit board 230 can be connected to the battery cell 220 through the first contact component 240 and the second contact component 250, so that the circuit board 230 can control the battery cell 220 to continuously supply power to the atomization unit.

[0038] In the structure of the first contact component 240, as Figure 4 As shown, the first contact assembly 240 includes a base 241 and a first elastic member 242 connected to each other, the base 241 is connected to the bottom wall of the first mounting position 211, and the first elastic member 242 abuts against the bottom end of the battery cell 220 and generates a recoverable deformation. Exemplarily, the first elastic member 242 is a spring in this embodiment, and of course it can also be a spring, etc., as long as it can generate a recoverable deformation, which is not limited here.

[0039] More specifically, in the connection method between the first contact component 240 and the bracket 210, a connecting column 213 is provided on the bottom wall of the first mounting position 211, and the base 241 of the first contact component 240 is detachably connected to the connecting column 213, so that the first contact component 240 can be easily assembled and disassembled, but the connection method between the first contact component 240 and the bracket 210 is not limited to this. It can be understood that the base 241 of the first contact component 240 can also be connected to the bottom wall of the first mounting position 211 by bonding, welding or screw connection.

[0040] In the structure of the second contact component 250, as shown in FIG. Figure 5 As shown, the second contact assembly 250 includes a fixing plate 251 and a second elastic member 252 fixedly connected to one side of the fixing plate 251 in the thickness direction, wherein one side of the fixing plate 251 abuts against the bracket cover 260, and the other side of the fixing plate 251 (i.e., the side connected to the second elastic member 252) fixes the top of the battery cell 220, so that the bracket cover 260 abuts against the second elastic member 252 and can also produce a recoverable deformation when abutting against the top of the battery cell 220.

[0041] Similar to the first elastic member 242, the second elastic member 252 may also be a spring or a spring sheet, which is not limited here. Further, in a specific embodiment, the fixing sheet 251 is an oil-absorbing cotton, and the side of the oil-absorbing cotton close to the battery cell 220 is coated with adhesive (such as 3M adhesive, double-sided adhesive or glue, etc.), so that the second elastic member 252 is bonded to one side of the oil-absorbing cotton through the adhesive, and the oil-absorbing cotton is bonded to the top of the battery cell 220 through the adhesive. In addition, by providing the oil-absorbing cotton, the oil-absorbing cotton can also absorb the atomized medium that may seep from the atomization unit, thereby effectively protecting the battery cell 220, preventing the battery cell 220 from being eroded by the atomized medium and avoiding the occurrence of a short circuit.

[0042] In this way, since the fixing plate 251 is fixedly connected to the top of the battery cell 220, the first contact component 240 will not move at will when the power supply unit 200 is assembled. As long as the bracket cover 260 is covered on the opening of the first mounting position 211, the bracket cover 260 can be abutted against the second contact component 250, thereby facilitating assembly and improving assembly efficiency.

[0043] In one embodiment, combined with Figure 4 and Figure 5 As shown, the battery cell 220 is a cylindrical structure, and has a first protrusion 221 and a second protrusion 222 of a certain thickness and diameter at its opposite ends, respectively. The first protrusion 221 and the second protrusion 222 serve as the positive electrode column and the negative electrode column of the battery cell 220, respectively, wherein the first protrusion 221 abuts against the first elastic member 242 of the first contact component 240, and the second protrusion 222 abuts against the second elastic member 252 of the second contact component 250 and fits against the fixing plate 251.

[0044] Preferably, the diameter of the fixing sheet 251 is larger than the diameter of the second protrusion 222, so that the fixing sheet 251 can completely cover the second protrusion 222, thereby making the fixing sheet 251 and the second protrusion 222 have a larger contact area, ensuring that the fixing sheet 251 can be more firmly fixed to the battery cell 220.

[0045] In one embodiment, the diameter of the fixing sheet 251 is 18 mm, the thickness of the first protrusion 221 and the second protrusion 222 are both 1 mm, and the diameter is 10 mm. In addition, the second elastic member 252 is 0.5 mm protruding relative to the fixing sheet 251 in a natural state. Such a size design can ensure that both ends of the battery cell 220 can be fully in contact with the first contact component 240 and the second contact component 250, respectively, to avoid poor contact, and can also ensure that the second elastic member 252 of the second contact component 250 is not only elastic, but also makes it easier for the fixing sheet 251 to fit the surface of the second protrusion 222 and not easy to fall off from the second protrusion 222.

[0046] In order to further prevent the battery cell 220 from short-circuiting due to contact with the atomized liquid or other liquids, an insulating film (not shown in the figure) is also provided on the outer surface of the battery cell 220, and the insulating film covers the outer surface of the battery cell 220 except for the first protrusion 221 and the second protrusion 222. Exemplarily, the insulating film is a heat shrink film, because the battery cell 220 generates heat when working, and the heat shrink film itself has the characteristic of shrinking when preheated, and can be more closely attached to the surface of the battery cell 220 when the battery cell 220 is heated, so as to better protect the battery cell 220 and prevent the battery cell 220 from short-circuiting.

[0047] In addition, if Figure 3 As shown, in order to save space for the power supply unit 200, the bracket 210 is provided with air holes 214 penetrating through both ends of the bracket 210 along the X direction, and the bracket cover 260 is provided with through holes 261 penetrating through both opposite sides of the bracket 210 in the X direction. The air holes 214 and the through holes 261 are coaxially arranged and interconnected, and the housing 100 is also provided with an air inlet hole, which is connected to the air inlet hole, the air hole 214 and the through hole 261 in sequence. In this way, when the user performs a suction action using the electronic atomization device 10, the airflow can enter the housing 100 from the air inlet hole, and flow through the air holes 214 and the through holes 261 in sequence into the atomization unit, and is mixed with the aerosol generated by the atomization medium and then inhaled into the mouth of the user.

[0048] It can be seen that the power supply assembly provided by the present application can complete the installation and removal of the battery cell 220 in a limited space at a relatively low cost. When the battery cell 220 needs to be loaded into the bracket 210, as long as the bracket cover 260 is covered on the opening of the first installation position 211, the bracket cover 260 can be abutted against the second contact assembly 250, and the second contact assembly 250 can be tightly pressed against the top of the battery cell 220, and the bottom of the battery cell 220 can be tightly abutted against the first contact assembly 240, so that the conduction of the circuit can be achieved and the good contact of the battery cell 220 can be ensured; when the battery cell 220 needs to be taken out, as long as the bracket cover 260 is opened, the battery cell 220 can be automatically ejected, so that the assembly and replacement of the battery cell 220 can be completed quickly, which greatly improves the assembly efficiency of the battery cell 220.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
