Dustproof electric fan

Abstract

The invention belongs to the field of domestic appliance equipment, and particularly discloses a dustproof electric fan. The dustproof electric fan comprises a pedestal used for supporting. The pedestal is fixedly connected with a vertical rod. A rotating disk is arranged at the rotor position of a motor. Blades which are circumferentially and evenly distributed are arranged on the edge of the rotating disk. The tops of supporting rods are fixedly connected with a circular ring made of a metal material. A plurality of metal rings are evenly distributed in a sliding chute. The top end of the side, far away from the rotating disk, of each blade is located in the sliding chute, and a circle of metal conducting ring is attached to the inner wall of the sliding chute and further located betweentwo certain adjacent metal rings. The conducting ring is externally connected with a wire connected with the ground. The front face and the back face of the circular ring are both provided with wirecollection rings in a central symmetry mode. A plurality of metal supporting bars which are evenly distributed are fixedly connected between the circular ring and the wire collection rings. Two electrodes located in the same loop are arranged on the pedestal and further communicate with the circular ring and the wire collection rings correspondingly. According to the scheme, the blades can be prevented from adsorbing dust, regular rotation of the blades is guaranteed, the fanning quality and efficiency are ensured, and potential safety hazards are reduced.

Description

technical field [0001] The invention belongs to the field of household appliances and specifically discloses a dustproof electric fan. Background technique [0002] An electric fan, commonly known as an electric fan, is a household appliance that uses a motor to drive the fan blades to rotate to speed up the air circulation. It is mainly used for cooling and relieving heat and air circulation. Electric fans are widely used in places such as homes, offices, shops, hospitals and hotels. [0003] Especially in summer, the frequency of use of electric fans has increased significantly. The electric fan is exposed to the external environment. The friction between the blades of the electric fan and the air is very easy to generate static electricity, which is necessary to absorb dust in the air.

AI Technical Summary

Problems solved by technology

[0003] Especially in summer, the frequency of use of electric fans has increased significantly. The electric fan is exposed to the external environment. The friction between the blades of the electric fan and the air is very easy to generate static electricity, which is necessary to absorb dust in the air. Too much dust not only affects the appearance, And it is easy to shorten the service life of the electric fan

The user needs to disassemble the electric fan to clean the dust on the blades. When re-installing it again, it will obviously bring a lot of inconvenience to the user. Not only is the work cumbersome, but improper operation will directly lead to damage to the electric fan; and frequent disassembly and installation It is easy to cause deviations in the installation of the blades, resulting in irregular rotation of the blades when the electric fan is working, and even the danger of the blades falling off; Long, the blades of the electric fan are also very prone to irregular rotation, etc., which will affect the fan efficiency and increase safety hazards
