Hand-held fan with thermal insulation layer

Abstract

The invention discloses a hand-held fan with a thermal insulation layer. The hand-held fan with the thermal insulation layer includes an inner shell. The hand-held fan with the thermal insulation layer is characterized in that: an air inlet groove is arranged on one side of the inner shell; a filter is arranged at a position of the inner side of the inner shell corresponding to the air inlet groove; a sealing stopper is fixedly installed on one side of the filter; a fan body is installed on one side of the sealing stopper away from the filter; a rubber sleeve is sleeved at the position of thefan body near the air outlet; an air pipe connecting groove is provided on one side of the rubber sleeve; an air outlet groove is provided on a side wall of the inner shell; an inner air pipe is fixedly connected to the inner side of the air outlet groove; and the end of the inner air pipe is connected to the air pipe connecting groove. According to the invention, a user rotates a driving gear, the driving gear drives a transmission gear to rotate, the transmission gear drives a tooth-row rod to move upward, the tooth-row rod drives the air outlet groove baffle to move upward, and the air outlet groove baffle blocks the air outlet groove; therefore, the thermal insulation of the hair dryer can be achieved only through the air layer between the inner shell and the thermal insulation outer layer.

Description

technical field [0001] The invention belongs to the technical field of hair dryers, and in particular relates to a hand-held fan with a heat insulation layer. Background technique [0002] At present, hair dryer products have penetrated into thousands of households, and the demand can be imagined. They are mainly divided into household hair dryers and professional hair dryers in hair salons. Household hair dryers include hotel hair dryers, ordinary household hair dryers, travel hair dryers, etc. The potential demand is to be small and portable. For traditional hair dryers, the plug structure of the power cord is mainly a disposable power cord that directly presses the plug and power cord into one body with the outer layer of insulating rubber. The power cord that is not easy to store severely limits and affects the convenience and convenience of hair dryer products. Shape design limitations. [0003] The object of the present invention is to provide a hand-held blower with...

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held blower with a heat-insulating layer to solve the problem that when using the existing hand-held hair dryer, it is difficult for the hand-held hair dryer to isolate the outer shell from the blower, so as to prevent the heat of the blower from being transferred to the shell , so that the external temperature of the hair dryer is too high. At the same time, the plug of the hand-held hair dryer and the power cord are directly pressed into a one-time power cord that is not easy to store. The hand-held hair dryer does not have a flat heating device, which is not easy to reduce the volume. And the air duct is single, it is difficult to increase the wind speed, there is no shock absorber at the hand-held hair dryer, the noise is relatively large, and the hair dryer does not use a non-conductive shell
