Problems solved by technology
[0002] Most of the current fans are mechanically fixed at a specific position, so that when the human body moves, the rotation direction of the fan cannot follow the human body. There are differences. If the speed is too high, it will easily cause people to catch a cold and have a fever. If the speed is too small, it will not give people a comfortable feeling.

The invention provides a human body following automatic speed regulation fan based on photoelectric induction. The human body following automatic speed regulation fan comprises a single chip microcomputer control module, wherein the input end of the single chip microcomputer control module is connected with an infrared temperature measurement module and a voltage comparison module, the voltage comparison module is used for inputting an electric signal of a photoelectric sensing matrix, the output end of the single-chip microcomputer control module is connected with a power supply driving module and a PWM motor speed regulation module, and the photoelectric sensing matrix comprises four photoelectric sensing modules. According to the human body following automatic speed regulation fan, sensors are installed in the four parallel directions around the fan, and the single-chip microcomputer controls a steering engine to act, so that the fan can rotate along with the movement direction of ahuman body; and the body temperature of the human body in front of the human body is measured through an infrared speed measuring module, so that the rotating speed of the fan is adjusted according to the body temperature of the human body.
Description
technical field [0001] The invention relates to a human body following automatic speed-adjusting fan based on photoelectric induction. Background technique [0002] Most of the current fans are mechanically fixed at a specific position, so that when the human body moves, the rotation direction of the fan cannot follow the human body. There are differences. If the speed is too high, it will easily cause people to catch a cold and have a fever. If the speed is too small, it will not give people a comfortable feeling. Other fans also have a similar situation. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a human body-following automatic speed-adjusting fan based on photoelectric induction. [0004] The present invention is achieved through the following technical solutions. [0005] A human body following automatic speed-adjusting fan based on photoelectric induction provided by the present inven...
