Automatic control device of air humidifier

Abstract

The invention discloses an automatic control device of an air humidifier, belonging to the technical field of electronics. The automatic control device comprises a power supply, a power circuit unit formed by a rectifier circuit, a voltage stabilizing circuit and a filter circuit, a microcontroller, a humidity sensor, a drive circuit, an air humidification unit and a relay, wherein the power supply is electrically connected with the input end of the rectifier circuit, the output end of the rectifier circuit is electrically connected with the input end of the voltage stabilizing circuit, the output end of a micro-voltage circuit is electrically connected with the input end of the filter circuit, the output ends of the filter circuit and the humidity sensor are electrically connected with the input end of the microcontroller, the output end of the microcontroller is electrically connected with the drive circuit, the output end of the drive circuit is electrically connected with the input end of the relay, and the output end of the relay is electrically connected with the input end of the air humidifier unit. The automatic control device, provided by the invention, has the advantages that the microcontroller controls the relay to open and close by the drive circuit through a signal from a temperature humidifier, so that the air humidification unit is controlled to work without manual control, and energy is saved.

Description

technical field [0001] The invention relates to an air humidifier, in particular to an automatic control device of the air humidifier, which belongs to the field of electronic technology. Background technique [0002] The existing air humidifiers on the market must be turned on and off manually. Most of the air humidifiers are always in working condition, even if the humidity in the air has reached the standard, as long as no one turns off the power , The air humidifier will continue to work until someone turns off the switch and disconnects the power supply, and the air humidifier will stop working, which is troublesome and wastes energy. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an automatic control device for an air humidifier, which can automatically control the opening and closing of the air humidifier without manual control and saves energy. [0004] In order to achieve the above object...
