Description

Double-power-supply fan convenient to fix

Technical Field

The utility model belongs to the technical field of the fan, concretely relates to double power supply fan convenient to it is fixed.

Background

Fan refers to a tool for cooling by generating wind in hot days. An electric fan is a device which is driven by electricity to generate air flow, and a fan arranged in the electric fan is electrified and then rotated into natural wind to achieve the effect of cooling. The working principle is that the electrified coil is stressed in a magnetic field to rotate. The energy is converted into mechanical energy mainly by electric energy, and meanwhile, because the coil has resistance, a part of 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 reason that the temperature rises together, when the electric fan works, because there is electric current that passes through the coil of electric fan, the wire is resistive, so will produce heat and outwards release heat inevitably, so the temperature will rise. 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. In life, fans are common in life, and the possibility of using small fans in life is increasing, but the small fans are also fixed by a support like a large fan at present, so that the applicability of the fans is reduced.

Therefore, in order to meet the current situation, it is urgently needed to design and produce a double-power-supply fan which is convenient to fix so as to meet the requirement of practical use.
