A smart fan with self-adaptive head swing angle

Abstract

The invention relates to an intelligent fan with the self-adaptive swing head angle and belongs to the technical field of intelligent fan structures. The intelligent fan comprises a swing mechanism used for driving a fan blade to rotate and swing left and right, an adjusting mechanism used for adjusting the fan blade to a space facing a human body and a swing amplitude control mechanism used for controlling the left and right swing amplitude of the fan blade. The swing mechanism, the adjusting mechanism and the swing amplitude control mechanism are all mounted on a stand column. The bottom ofthe stand column is mounted on a cylindrical support rod. Four pyroelectric human body infrared sensors on the same horizontal plane are mounted on the outer wall of the support rod. A single chip microcomputer in communication with the pyroelectric human infrared sensors is mounted in the support rod. The swing mechanism, the adjusting mechanism and the swing amplitude control mechanism are all controlled by the single chip microcomputer. The intelligent fan has the beneficial effects of simple structure design and low energy consumption and can automatically adjust the fan angle according tothe change of the range of a user.

Description

technical field [0001] The invention relates to an intelligent fan with self-adaptive head swing angle, which belongs to the technical field of intelligent fan structures. Background technique [0002] With the development of the air-conditioning industry in recent years, electric fans were once regarded as a "sunset industry". There are differences in nature between fans and air conditioners. Compared with air conditioners, fans have the following advantages: [0003] 1. By accelerating the air flow, it promotes the rapid evaporation of sweat, making the body feel cool without [0004] Has a cooling effect; [0005] 2. The price is cheaper than air conditioners (usually less than 1,000 yuan); [0006] 3. Small power and low power consumption; [0007] 4. Suitable for all ages. [0008] The comparison between fans and air conditioners shows that there are significant differences between fans and air conditioners in terms of working principle, energy consumption, health ...

AI Technical Summary

Problems solved by technology

[0013] Although the current fans have various functions, shapes, and functions, there is still no more intelligent smart fan whose swing range can be changed according to the range of the user.

At present, the fan is ubiquitous and the problem that users generally find inconvenient and has not been solved is "the swinging angle of the fan is fixed".
