Description

Neck-hanging fan

Technical Field

The utility model relates to a fan field specifically is a hang neck fan.

Background

Fan refers to a tool for cooling by generating wind in hot days. The electric fan is a device which is driven by electricity to generate air flow, and the fan arranged in the electric fan rotates after being electrified, so that the electric fan is converted into natural wind to achieve the cooling effect. The main components of the electric fan are: an AC motor. The working principle is as follows: the electrified coil is forced to rotate in the magnetic field. The form of energy conversion is: the electric energy is mainly converted into mechanical energy, and meanwhile, because the coil has resistance, a part of the electric energy is inevitably converted into heat energy. When the electric fan works (assuming that the room has no heat transfer with the outside), the temperature in the room is not reduced, but is increased. Let us analyze the cause of the temperature rise together: when the electric fan works, because current passes through the coil of the electric fan and the conducting wire has resistance, heat is inevitably generated and released outwards, so the temperature is increased. But why do people feel cool? Because a large amount of sweat exists on the surface of a human body, when the electric fan works, indoor air flows, so that rapid evaporation of the sweat can be promoted, and people feel cool by combining the fact that evaporation needs to absorb a large amount of heat.

But the general whole kind of present fan is more, the kind of hanging neck formula electric fan is relatively less, the demand that is adapted to existing market that can not be fine, the existing market hanging neck fan casing on the existing market simultaneously is mostly plastics material integrated into one piece, do not possess many scenes and be suitable for the demand, can not set up flexible shapable return bend through in the casing junction, carry out the bending of angle, the crookedness is adjusted according to the use scene of difference that also can not be fine, be not enough to satisfy motion class crowd's demand.
