[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , a fan driven by an electric tool battery pack, including a fan main body 1 and a circuit adapter board 2 provided on one side of the fan main body 1. The output end of the circuit adapter board 2 is electrically connected to the input end of the fan main body 1. It is characterized in that a battery pack 3 for driving the fan main body 1 is provided outside the circuit adapter board 2. Through the battery adapter, the fan can be normally used relying on the electric tool battery pack when the power cannot be connected through wires. At the same time, relying on multiple battery adapters, when the power of a single electric tool battery pack is insufficient, the fan can rely on other electric tool battery packs to ensure that the operation of the fan will not be interrupted, and multiple electric tool battery packs can also supply power to the fan simultaneously through multiple battery adapters when the power supply of a single electric tool battery pack is insufficient.

[0028] In some embodiments: The battery pack 3 includes a plurality of battery adapters 32 mounted on the circuit adapter board 2 and a plurality of electric tool battery packs 31 that correspond one by one to the plurality of battery adapters 32 and can provide power for the fan main body 1 to operate. The output end of the battery adapter 32 is electrically connected to the input end of the circuit adapter board 2, and the output end of the electric tool battery pack 31 is electrically connected to the input end of the battery adapter 32.

[0029] In some embodiments: A battery accommodation groove 321 for accommodating a partial area of the power tool battery pack 31 is formed on the outer side of the battery adapter 32. A fixing groove 322 for limiting a partial area of the power tool battery pack 31 located inside the battery accommodation groove 321 is formed on the inner wall of the battery accommodation groove 321. A connecting portion 311 that cooperates with the battery accommodation groove 321 is formed by a protrusion on one side of the power tool battery pack 31, enabling the power tool battery pack 31 to be connected to the battery adapter 32. Guide ribs 312 that cooperate with the fixing groove 322 are provided on both sides of the connecting portion 311. After the guide ribs 312 enter the fixing groove 322, they will form a limit, preventing the connecting portion 311 from falling out of the battery accommodation groove 321. Two interfaces are formed at the bottom end of the connecting portion 311, and first conductive terminals 313 are provided inside the interfaces. Second conductive terminals 323 that cooperate with the first conductive terminals 313 are provided inside the battery accommodation groove 321. The first conductive terminals 313 are the output terminals for electrical connection of the power tool battery pack 31, and the second conductive terminals 323 are the input terminals for electrical connection of the battery adapter 32.

[0030] The specific power supply process is as follows: When installing the power tool battery pack 31 onto the battery adapter 32, align the connecting portion 311 with the battery accommodation groove 321. After alignment, push the power tool battery pack 31 towards the battery adapter 32, causing the connecting portion 311 to enter the inside of the battery accommodation groove 321. After a part of the connecting portion 311 enters the inside of the battery accommodation groove 321, the guide ribs 312 will enter the inside of the fixing groove 322, thereby limiting the connecting portion 311. When the connecting portion 311 completely enters the inside of the battery accommodation groove 321, the second conductive terminals 323 will also enter the inside of the first conductive terminals 313, causing the second conductive terminals 323 to contact the first conductive terminals 313, thereby forming an electrical connection. After the electrical connection is formed, the installation of the power tool battery pack 31 is completed. After the power in the power tool battery pack 31 is transmitted to the battery adapter 32, the battery adapter 32 then transmits the power to the circuit adapter board 2, and then through the circuit adapter board 2 to the fan main body 1, enabling the fan main body 1 to operate. When the power of the power tool battery pack 31 is exhausted, the power tool battery pack 31 can be pushed in a direction away from the battery adapter 32, causing the connecting portion 311 to leave the inside of the battery accommodation groove 321, detaching the power tool battery pack 31 from the battery adapter 32, and taking the power tool battery pack 31 for charging.

[0031] Meanwhile, the power tool battery pack 31 can be a lithium battery for power tools that can be purchased on the market. In this way, when the power tool battery pack 31 is not used on the fan main body 1, it can be used on power tools, increasing convenience.

[0032] In some embodiments: A bracket 4 is provided on the outer side of the fan body 1. The circuit adapter board 2 is installed on one side of the bracket 4. The fan body 1 is hinged to the bracket 4. The bracket 4 is divided into a base frame 45 and a side bracket 46 responsible for hinging with the fan body 1. An arc-shaped limiting groove 41 is formed on the outer side of the fan body 1. The side bracket 46 is provided with a limiting rod 42 that cooperates with the arc-shaped limiting groove 41. One end of the limiting rod 42 passes through the arc-shaped limiting groove 41 and extends into the fan body 1 and can move relatively along the arc-shaped limiting groove 41. A locking member 11 is provided between the fan body 1 and the side bracket 46 for fixing the flipping angle of the fan body 1 relative to the side bracket 46. The cooperation between the arc-shaped limiting groove 41 and the limiting rod 42 can limit the flipping angle of the fan body 1 to avoid excessive flipping. A locking member 11 is provided between the fan body 1 and the bracket 4 for fixing the angle of the fan body 1. The fan body 1 can be locked at the current angle through the locking head 12, avoiding the fan body 1 returning to the vertical state because it is not fixed after the vertical angle adjustment is completed.

[0033] In some embodiments: A runner 43 is installed at one end of the base frame 45, and a hollow spacer 44 is provided at the other end of the base frame 45. The runner 43 facilitates the user to move the bracket 4 when the user wants to move the bracket 4. The spacer 44 can play a supporting role when the user does not move the bracket 4, so that the bracket 4 will not move by itself due to the runner 43 when placed.

[0034] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
