AI Technical Summary
Technical Problem
In dusty environments, the air intake protection structure of existing hair dryers is easily clogged by fine dust, resulting in reduced airflow and weakened airflow, which affects the efficiency and lifespan of the equipment.
Method used
An electric hair dryer with a filter plate and a cleaning rod was designed. The filter plate has a smooth surface to reduce dust adhesion, and the cleaning rod is cleaned by a brush. Combined with a limiting mechanism to stabilize the moving rod, it ensures smooth air intake.
Benefits of technology
It effectively prevents dust blockage, ensures smooth airflow, extends equipment life, and improves efficiency and safety.

Abstract
The utility model discloses an electric hair dryer which comprises a handle and a shell, the top end of the handle is fixedly connected with the shell, the right side of the shell is fixedly connected with a connecting sleeve, a fixing ring is inserted into the connecting sleeve, a filter plate is fixedly inserted into the fixing ring, the right side of the fixing ring is fixedly connected with an air inlet, and the air inlet is fixedly connected with an air outlet. A circular groove is formed in the center position of the air inlet, a second movable rod is inserted into the circular groove, a first movable rod is fixedly connected to the left side of the second movable rod, and a hole groove is formed in the center position of the filter plate. Fine dust can be filtered through the filter plate, the surface of the filter plate is subjected to smooth treatment (such as electroplating and spraying of an oleophobic layer), so that dust is not easy to attach, is more easily blown away by airflow or is easy to fall off during cleaning, and stubborn stains adhered to the surface of the filter plate can be cleaned through rotation of the fixing ring; smooth air inlet is guaranteed, the anti-blocking effect is achieved, and the service life of the blower is prolonged.
