Description

Technical Field

[0001] The utility model relates to the field of hair dryer rear covers, in particular to a hair dryer rear cover structure. Background Art

[0002] A hair dryer is a tool for drying and styling hair, which is composed of a group of electric heating wires and a small fan. Some hair dryers use the principle of fluid mechanics to increase the size of the air outlet. The middle of the hair dryer is hollowed out, and a circle of air outlets is wrapped around the outer circle of the hollow part. The air flow of the air outlet drives the air flow in the hollow part. Often, such hair dryers have a hair dryer back cover, and a mounting port is provided at one end of the hair dryer back cover, and an air inlet is provided at the other end. The aperture of the existing hair dryer back cover is usually too large. Users may accidentally let their hair pass through the air inlet net and contact with the fan, causing entanglement, resulting in safety hazards. In addition, the hair is noisy during use, and it is inconvenient to clean the dust on the back cover, which has certain adverse effects on people's use process. Therefore, we propose a hair dryer back cover structure. Utility Model Content
