Automatic energy saving device of pivoting fan

Abstract

The invention relates to an automatic energy saving device of a pivoting fan. A speed adjustable air supplying motor with multiple input gears and a turning motor are installed in a main body; the automatic energy saving device further comprises an infrared sensing head unit, an infrared sensing module and a motor rotating speed control module, wherein the infrared sensing head unit is located at the front of the main body of the pivoting fan, the infrared sensing module is further arranged on the basis of an inner power device; and the infrared sensing module receives singles of the infrared sensing head unit, and when human heat energy is detected, voltage signals are sent to control a relay of the motor rotating speed control module to switch the input ends of the air supplying motor and the turning motor, and the working powers of the air supplying motor and the turning motor are changed, so that when the pivoting fan faces towards an area without human, the power of the air supplying motor is reduced, and the rotating speed of the turning motor is increased. The purpose that air supplying volume and the turning speed can be automatically adjusted according to positions of human bodies, so that the energy consumption of the whole pivoting fan is reduced, and meanwhile, the quality of blowing experience of the human bodies is improved; and the automatic energy saving device is beneficial for human health, the structure is simple, and the automatic energy saving device can be applied to the mechanical switch type pivoting fan.

Description

technical field [0001] The invention relates to an energy-saving device for automatic adjustment of air supply equipment according to environmental requirements, in particular to an automatic energy-saving device for a mechanical switch type oscillating fan. Background technique [0002] In daily life, electric air supply equipment based on oscillating fans is a commonly used air conditioning equipment. It is mainly used for blowing air, cooling the human body, or circulating local air. This type of air supply equipment includes vertical oscillating head Fans, tower-type oscillating fans, bladeless oscillating fans, and air outlet structures in air-conditioning equipment. This kind of air supply equipment generally includes a main motor and auxiliary blades for generating directional blowing, and also includes a set of devices that can change the direction of the wind. Generally, the purpose is achieved by changing the angle of the fan body or the wind guide blades by turnin...

AI Technical Summary

Problems solved by technology

Due to the general working environment, it is impossible to be full of people within the air supply range, so there is no uninhabited area where there is no human body, and the electric energy of the fan is wasted. When there are fewer people in the air supply range, the degree of power waste is higher

Moreover, a single human body needs to be blown once at a long interval, and the cooling experience is not good.

[0003] In the patent No. 2010205968567, a shaking head electric fan that can automatically track the human body is announced. By using the infrared sensor head to sense the infrared heat energy of the human body, the steering motor is controlled by the circuit to lock the human body. The structure of the machine is complicated, and the function is limited. For example, it cannot meet the air supply needs of multiple human bodies, and the so-called tracking human body blowing is equivalent to directional blowing when the human body does not move, and the human body is less comfortable to be exposed to wind, so it has limitations and has no energy-saving effect

[0004] At present, in foreign markets, a new "human body perception shaking head fan" has been newly developed, which can be regarded as an improved version of the above technology. This technology uses a regional infrared sensing device to judge the distribution of human body within the air supply range, and then through intelligent The circuit adjusts the air supply mode and air supply range, which not only has excellent energy-saving effect, but also has better comfort for the human body. can be used universally

[0005] The above two technologies all have the defect of complex structure, and cannot be applied to the mechanical switch type oscillating fans commonly used at present.
