Abstract

The invention discloses a telescopic fan which comprises a fan support and a shell which is arranged on the circumferential periphery of the fan support in a sleeving manner and connected with the fansupport in a sliding manner. A folding fan blade set is installed at one end of the fan support, and a fan motor and a circuit board assembly are installed in the support. The fan motor is electrically connected with the circuit board assembly. The folding fan blade set is in drive connection with the fan motor. When the fan support slides towards the end away from the folding fan set relative tothe shell, the folding fan blade set is stored in a cavity of the shell. By means of the telescopic fan, in the process that the fan support stretches and contracts, a corresponding stroke positioning structure is arranged so that it can be ensured that the fan cannot be dislocated in the use state or in the storage state, and normal use of the fan is ensured; and in addition, in the stretching and contracting operation process of the fan, a circuit triggering switch can be automatically triggered, the opening and closing state of the fan can be automatically controlled, and people can control and use the functions of the fan conveniently.

Description

technical field [0001] The present invention relates to the technical field of fans, and more specifically relates to a telescopic fan. Background technique [0002] Fan refers to a device used to generate wind to keep cool in hot weather. The electric fan is a device driven by electricity to generate air flow. The fan inside is energized and then rotates into natural wind to achieve the effect of enjoying the cool. [0003] Traditional fans are either placed on the countertop or held in the hand. They are relatively large in size and inconvenient to carry around. Therefore, if there is a small fan that is easy to store and store, and has stable performance , It is undoubtedly convenient for people to carry and use it when they go out. Contents of the invention [0004] The purpose of the present invention is to provide a telescopic fan, which can be stored and hidden in the casing when not in use, and is small in size and easy to carry. At the same time, a corresponding...
