Description

Portable silence hangs neck fan

Technical Field

The utility model relates to a hang neck fan field, specifically a portable silence hangs neck fan.

Background

The 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, and mechanical energy is converted into wind energy, so that natural wind is formed to achieve a cool effect. 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, the room is supposed to have no heat transfer with the outside, and the indoor temperature is not only not reduced but also 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 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 the rapid evaporation of the sweat can be promoted, and people can feel cool by absorbing a large amount of heat in combination with the evaporation.

Traditional string of neck fan, when using, holistic air-out effect is relatively poor, wholly can only carry out the side and blow, wholly can't effectually carry out quick cooling, at the in-process that uses, holistic noise is also great relatively, owing to hang on the neck, form osteoacusis easily, sound too big can cause certain injury to the human body, the human body produces irritated psychology easily, holistic silence effect is relatively poor, can not effectually play the effect of silence.
