Description

A Portable Rechargeable Waist-mounted Fan

technical field

The utility model relates to a daily necessities, in particular to a portable charging waist hanging fan.

Background technique

Fan refers to a device used to generate wind to keep cool in hot weather. The electric fan is a device driven by electricity to generate air flow. The fan inside is energized and then rotates into natural wind to achieve the effect of enjoying the cool.

The main components of the electric fan are: AC motor. Its working principle is: the energized coil is forced to rotate in the magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and because the coil has resistance, it is inevitable that a part of the electrical energy will be converted into heat energy.

But the volume of existing electric fan is all bigger, mainly is divided into three kinds of floor type, table top and clamping type, but these three kinds of electric fans are not suitable for carrying, because its volume is bigger, it is inconvenient to carry, and existing Portable fan blades have certain disadvantages. It uses a DC brush motor, which is noisy and has a short lifespan. The lifespan is about 800 hours. The power is about 7.5W. The structure is complex and must be connected to an external power source, which is inconvenient to use.
