Problems solved by technology

There is a kind of small-sized electric fan on the market now according to the visor electric fan on the forehead of the cap, blowing the face, this visor electric fan has the following shortcoming: 1, it is inconvenient in situations such as work, study and leisure Use; 2. The direction of the electric fan cannot be adjusted, and the wind force of the fan is too small to blow air on the chest and belly of the human body with high heat generation; 3. The wind will blow to the eyes, which is not conducive to study and work; 4. The motor is installed on the The visor is heavy and vibrates, which makes people feel uncomfortable and affects work and study; 5. The battery capacity is too small, the working time of the motor is short, and the visor fan is very unsightly
At the same time, it has a large noise, which not only makes people irritable, affects the mood, but also affects the quality of life

Abstract

The invention discloses a magnetic levitation electric fan, which comprises a base provided with a power supply and a switch, a DC motor, fan blades, a repulsion sleeve and a magnetic layer sleeve, the magnetic layer sleeve is coaxially sleeved on the DC motor, and the outer surface of the magnetic layer sleeve is A permanent magnet is laid, and the repulsive force sleeve is set on the outer side of the magnetic layer cover in cooperation. The invention has the advantages of simple structure, convenient use and portability, and utilizes the permanent magnet type magnetic levitation structure to reduce the vibration noise during the operation of the motor and improve the use comfort.

Description

technical field [0001] The invention relates to a fan, in particular to a magnetic levitation electric fan. Background technique [0002] In order to resist the heat of summer, fans have existed since ancient times, such as cattail fans and hydraulic fans. Now with the mature development and large-scale application of electric power technology, electric fans have become another main force for ventilation and coolness in the home besides air conditioners. Due to the large volume and the requirement for power supply, the AC fan is relatively fixed when used in summer and is not easy to carry. The fan of the DC motor is convenient for people to carry by means of a DC power supply and a tiny DC motor. There is a kind of small-sized electric fan on the market now according to the visor electric fan on the forehead of the cap, blowing the face, this visor electric fan has the following shortcoming: 1, it is inconvenient in situations such as work, study and leisure Use; 2. The ...
