Multifunctional mini-type electric fan

Abstract

The invention discloses a multifunctional mini-type electric fan. The multifunctional mini-type electric fan comprises a fan cover, wherein blades are arranged in the fan cover. The multifunctional mini-type electric fan is characterized by further comprising a charge pal, wherein the fan cover is arranged on the charge pal; the charge pal and the fan cover are connected and matched in a detachable slide rail and slide groove manner; conductive lumps which are in contact with each other are further arranged on the contact surfaces of the fan cover and the charge pal. According to the mini-type electric fan, the charge pal is simple to detach, and can be charged to provide a power supply to the blades, and also can provide the power supply to other current-using equipment, so that the multifunctional mini-type electric fan has many functions; the slide rail and slide groove type charge pal is in detachable connection and match with the fan cover so that the whole structure of the product is simple and reasonable, and the product is convenient to charge and use.

Description

technical field [0001] The invention relates to the technical field of miniature electric fans, in particular to a portable multifunctional miniature electric fan. Background technique [0002] At present, miniature electric fan is liked by people because of its convenience of carrying; Inside the fan cover, a battery and a circuit board are installed on the lower part of the housing. The battery supplies power to the circuit board, and the circuit board controls the rotation of the fan blades; however, the above-mentioned traditional miniature fans still have the following disadvantages: (1) Since the miniature electric fan is mostly used for carrying out, when the power of the battery is used up, the fan needs to be replaced before the fan can continue to work, which brings great inconvenience to the user; (2) due to the single function of the electric fan, only As a fan, if the user goes out to use it, it often needs other auxiliary functions, such as: it cannot be used ...

Problems solved by technology

[0002] At present, miniature electric fan is liked by people because of its convenience of carrying; Inside the fan cover, a battery and a circuit board are installed on the lower part of the housing. The battery supplies power to the circuit board, and the circuit board controls the rotation of the fan blades; however, the above-mentioned traditional miniature fans still have the following disadvantages: (1) Since the miniature electric fan is mostly used for carrying out, when the power of the battery is used up, the fan needs to be replaced before the fan can continue to work, which brings great inconvenience to the user; (2) due to the single function of the electric fan, only As a fan, if the user goes out to use it, it often needs other auxiliary functions, such as: it cannot be used as a power bank, etc. Therefore, the existing miniature electric fan has a single function and cannot meet the needs of different users; (3) Although there are some The micro electric fan uses a lithium battery (rechargeable) as a power source, but the lower part of the housing where the lithium battery is located is an integral structure that cannot be disassembled with the housing (that is, the charging part cannot be disassembled). Therefore, when charging, it is often necessary to Take the whole electric fan together for charging, which will cause some inconvenience to users
