Automatic temperature control fan

Abstract

An automatic temperature-controlled fan, comprising a temperature detection module, a human body sensing module, a single-chip microcomputer, a digital tube, a drive module and a fan body; The signal is transmitted to the single-chip microcomputer and displayed through the digital tube; the upper limit value and the lower limit value of the preset temperature are set in the single-chip microcomputer. If the external ambient temperature is lower than the lower limit value of the preset temperature, the control drive module will stop working. Between the upper and lower limits of the preset temperature, the drive module controls the fan body to operate at a low speed. If it is higher than the upper limit, the drive module controls the fan body to operate at a high speed; the human body sensor module is used to control the rotation of the fan body. stop, its axis of rotation is oriented horizontally or vertically. The automatic temperature control fan of the present invention can adjust the wind power of the fan arbitrarily, and automatically control its rotation and stop.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an automatic temperature-controlled electric fan. Background technique [0002] Although many urban households now use air conditioners, electric fans are still used as cooling and heatstroke prevention equipment in rural areas that account for the majority of the population in China. During the alternation of spring and summer (summer and autumn), the temperature during the day is still very high, and the electric fan should rotate at a high speed and with a large air volume to make people feel cool. At night, when the temperature drops, especially when people fall asleep, the speed should be gradually reduced to avoid catching a cold. [0003] Although electric fans have the function of adjusting different gears, people must manually change gears, and there is nothing they can do when they fall asleep. The method of turning off the timer generally adopted by peop...

AI Technical Summary

Problems solved by technology

The way that people generally use the timer to turn off, on the one hand, the length of the timer is limited, usually one or two hours; Waking up in the heat and having to get up to turn the fan back on and increase the timer is a hassle

Sometimes the last timing time may be too long after multiple timings, and the fan will continue to blow air after the temperature drops, making people prone to catch a cold
