As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0027] See also Figure 1-3 The present invention provides an electric fan that supports multiple power supply modes. The electric fan can be powered by batteries and external power sources, such as mains electricity. Specifically, the electric fan that supports multiple power supply modes includes a rechargeable battery 2, a battery adapter plate 5, a power plug 4, an adapter 10, a drive device 20, and a base 30. The specific structure is described as follows:

[0028] The rechargeable battery 2 can be, for example, a lithium battery, which is not specifically limited in the present invention. The rechargeable battery 2 is detachably mounted within the base 30. When the rechargeable battery 2 is mounted within the base 30, power can be supplied by the rechargeable battery 2. When charging is required, the rechargeable battery 2 can be removed from the base 30.

[0029] The power plug 4 is embedded in the base 30; it is connected to the drive device 20 and is removably connected to the adapter 10, which is used to connect to an external power source. The adapter 10 converts the external power source into a power source suitable for the electric fan, thereby providing power to the external power source. By adopting the design of the adapter 10, only the power plug 4 is required on the base 30, eliminating the need for a power cord. When external power is required, the adapter 10 is connected to the power plug 4 and the external power source respectively. When power is supplied by the rechargeable battery 2, the power plug 4 does not need to be connected to the adapter 10, thus avoiding the constraints of a wiring harness.

[0030] The rechargeable battery 2 is connected to the battery adapter plate 5, and the battery adapter plate 5 is connected to the driving device 20. The rechargeable battery 2 supplies power to the driving device 20 through the battery adapter plate 5. It can be understood that the driving device 20 is a driving device for the fan motor, which is used to drive the motor to operate.

[0031] The technical solution of the present invention, by adopting the design of the adapter 10, only the power plug 4 is required on the base 30, eliminating the need for a power cord. When powered by the rechargeable battery 2, the power plug 4 does not need to be connected to the adapter 10, thus avoiding the constraints of a wiring harness. Furthermore, when the rechargeable battery 2 is depleted, external power can be supplied through the adapter 10 and the power plug 4, thereby improving battery life and avoiding the safety hazards associated with simultaneous charging and use. This shows that the technical solution of the present invention balances battery life with convenience and safety.

[0032] Furthermore, the base 30 includes a bottom shell 3 and a battery cover 1. The bottom shell 3 is provided with a battery slot 31. The rechargeable battery 2 is detachably arranged in the battery slot 31, and the battery cover 1 is detachably covered on the battery slot 31. The bottom shell 3 and the battery cover 1 can both be made of plastic, which is not specifically limited in the present invention. The battery cover 1 can provide better protection for the rechargeable battery 2. At the same time, the detachable design of the battery cover 1 makes it easy to remove the rechargeable battery 2 for charging. The volume of the rechargeable battery 2 is smaller than that of the battery slot 31, so that the rechargeable battery 2 can be completely accommodated in the battery slot 31.

[0033] Furthermore, a first mounting portion 11 is provided on one side of the battery cover 1, extending parallel to the battery cover 1. A first mounting slot 311 is provided on the bottom shell 3, located on one side of the battery slot 31. The opening of the first mounting slot 311 is parallel to the surface of the bottom shell 3. The first mounting portion 11 can be removably inserted into the first mounting slot 311. Because the opening of the first mounting slot 311 is parallel to the surface of the bottom shell 3, inserting the first mounting portion 11 into the first mounting slot 311 restricts movement of the battery cover 1 in a direction perpendicular to the battery cover 1. The first mounting portion 11 can form a snap-fit ​​structure with the first mounting slot 311 to improve connection reliability. The first mounting portion 11 can be integrally formed with the battery cover 1.

[0034] Furthermore, a second mounting portion 12 is provided on the other side of the battery cover 1, for example, on the side opposite the first mounting portion 11. The second mounting portion 12 extends at an angle, such as perpendicular, to the battery cover 1. The bottom case 3 is provided with a second mounting slot 312, which is provided on the other side of the battery slot 31, for example, on the side opposite the first mounting slot 311. The opening of the second mounting slot 312 is angled, such as perpendicular, to the surface of the bottom case 3. The second mounting portion 12 is removably inserted into the second mounting slot 312. Because the opening of the second mounting slot 312 is angled, such as perpendicular, to the surface of the bottom case 3, the second mounting portion 12 is inserted into the second mounting slot 312 to restrict the movement of the battery cover 1 in a direction parallel to the battery cover 1. The second mounting portion 12 can form a snap-fit ​​structure with the second mounting slot 312 to improve connection reliability. The second mounting portion 12 can be integrally formed with the battery cover 1.

[0035] Furthermore, the number of the first mounting portion 11, the first mounting groove 311, the second mounting portion 12 and the second mounting groove 312 are all multiple, and the multiple first mounting portions 11 can be removably embedded in the multiple first mounting grooves 311; the multiple second mounting portions 12 can be removably embedded in the multiple second mounting grooves 312.

[0036] For example, the number of the first mounting portion 11 , the first mounting groove 311 , the second mounting portion 12 , and the second mounting groove 312 are all two.

[0037] Furthermore, a third mounting slot 313 is provided in the battery slot 31, and one end of the battery adapter plate 5 is disposed in the third mounting slot 313. When the battery is installed in the battery slot 31, the rechargeable battery 2 is connected to the end of the battery adapter plate 5 disposed in the third mounting slot 313. Specifically, a first contact piece is provided at one end of the battery adapter plate 5, and a second contact piece is provided on the rechargeable battery 2. The first contact piece contacts the second contact piece, thereby connecting the rechargeable battery 2 to the adapter plate.

[0038] Furthermore, the bottom shell 3 further includes a power supply port 32, and the power plug 4 is embedded in the power supply port 32. One end of the power plug 4 can be inserted into the adapter 10.

[0039] The bottom housing 3 also includes a retaining groove 34, which is located inside the power port 32. One side of the power plug 4 is embedded in the retaining groove 34. The shape of the retaining groove 34 matches the shape of the power plug 4. For example, the retaining groove 34 is semicircular. The retaining groove 34 secures the end of the power plug 4.

[0040] Furthermore, the bottom shell 3 further includes two first ribs 33, which are provided on both sides of the power supply port 32. The two first ribs 33 clamp the bottom of the power plug 4. The two first ribs 33 can reliably clamp the bottom of the power plug 4 to prevent the power plug 4 from shaking.

[0041] Furthermore, the base 30 includes a decorative ring 6 and a footrest 7. The decorative ring 6 is disposed between the bottom shell 3 and the footrest 7. The decorative ring 6, the bottom shell 3, and the footrest 7 are assembled together by fasteners. The fasteners can be, for example, screws, which are not specifically limited in this invention.

[0042] The decorative ring 6 is provided with two second ribs 61, which are provided on both sides of the power supply port 32. The two second ribs 61 clamp the top of the power plug 4. The two second ribs 61 can reliably clamp the top of the power plug 4 to prevent the power plug 4 from shaking.

[0043] The two first ribs 33 and the two second ribs 61 are aligned with each other, for example, in a vertical direction, so as to wrap the power plug 4 .
