Practical electric fan device

Abstract

The invention discloses a practical electric fan device which comprises a shell sleeve, wherein hanging arms are fixedly arranged at the left parts of the front and rear end surfaces of the shell sleeve; hanging holes allowing screws to penetrate are formed in the hanging arms; a second sliding connection groove and a first sliding connection groove which is formed in the rear end of the second sliding connection groove are formed in the shell sleeve; a left tooth connection groove and a right tooth connection groove are respectively formed in the shell sleeve at the left end and the right end of the first sliding connection groove; a sealing groove is formed in the right end surface of the shell sleeve; an insertion groove is communicated between the sealing groove and the first sliding connection groove; a left screw rod and a right screw rod which are propped into the left tooth connection groove and the right tooth connection groove and are in rotational matching connection with the shell sleeve are arranged in a rear part position of the first sliding connection groove. The practical electric fan device is simple in overall structure, relatively low in production cost and safe and stable in power supply.

Description

technical field [0001] The invention relates to the field of hair dryer equipment, in particular to a practical hair dryer device. Background technique [0002] After washing hair, people usually use a hair dryer to dry their hair. When using it, they will aim at the hair from all angles, so the angle of the hair dryer will also change. They are all connected by friction fit. Long-term plugging and unplugging are prone to loosening, and there is no other locking device, so when people use it, it is easy to pull the plug of the hair dryer from the socket, so that the power failure affects the use of the hair dryer, and Existing sockets connected to hair dryers are all directly charged, so electric shock accidents are likely to occur when inserting plugs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a practical hair dryer device, which can solve the above-mentioned problems in the prior art. [0004] In order ...
