Detailed Description

Embodiment 1, as shown in fig. 1, this embodiment is a currently popular mobile electric fan, which can be conveniently hung around the neck during operation, and can liberate both hands during operation, and practically includes two electric fans 300 supported by support arms, which are a first support arm 100 and a second support arm 200, respectively, and magnets 1 are mounted at the ends of the two support arms, so that the first support arm 100 and the second support arm 200 are connected with each other, and thus, the two support arms form an inward surrounding shape after being connected, and can be hung around the neck. In this embodiment, the first arm 100 and the second arm 200 may be independent arms, have the same shape, or may be different, each arm is provided with a control circuit for a battery and an electric fan, and may be used independently, or may be hung around the neck by using a magnet, which is very convenient for people with long hair, and when needing to hang around the neck, the arms need to be extended backward from both sides along the neck, and the two arms may be connected together due to the effect of the magnet.

In practice, a battery and a control circuit can be arranged in one arm, and the electric fan 300 on the other arm can also be electrically connected by using a connecting mechanism such as a spring plate, a plug and the like at an interface, so that the battery and the control circuit in one arm can supply power for the electric fan on the other arm.

Embodiment 2 as shown in fig. 2, it is different from embodiment 1 in that a screw 2 and a screw hole 3 are connected with each other to connect two arms.

Embodiment 3 as shown in fig. 3, two arms are connected to each other by means of pin fitting, and the two arms are connected to each other by means of corresponding sockets 5 of pins 4 at the interface, generally two pins 4 and corresponding sockets 5, and the first arm 100 and the second arm 200 of two live fans 300 can be connected by inserting the sockets 5 into the pins 4.

Embodiment 4 as shown in fig. 4, it is a snap fit to connect two arms, as shown in fig. 4, a latch 6 is provided at the interface of the first arm 100 and the second arm 200, a bayonet 7 is provided at the interface of the second arm 200 and the first arm 100, when the latch is inserted into the bayonet and is slightly rotated, the two arms can be connected.

Embodiment 5 is shown in fig. 5, which is a two support arms matching in a twist-button manner, wherein a ring-shaped twist bolt 8 is arranged at the interface of the first support arm 100 and the second support arm 200, a ring-shaped twist opening 7 is arranged at the interface of the second support arm 200 and the first support arm 100, and when the twist bolt is inserted into the twist opening and slightly rotated, the two support arms can be connected.
