Automatic water adding control system for humidifier based on voltage-stabilization-type rectifier and filter circuit

Abstract

The invention discloses an automatic water adding control system for a humidifier based on a voltage-stabilization-type rectifier and filter circuit. The system is characterized in that the system is mainly formed by a central processor, an A/D converter, a preset value storage unit, an automatic water adding control circuit, a displayer, a power source, a water level sensor, a solenoid valve, a rectifier and filter circuit and a power source voltage regulator circuit, wherein the A/D converter, the preset value storage unit, the automatic water adding control circuit, the displayer and the power source are connected with the central processor; the water level sensor is connected with the A/D converter; the solenoid valve is connected with the automatic water adding control circuit; the rectifier and filter circuit is connected in series between the power source and the water level sensor; and the power source voltage regulator circuit is connected in series between the power source and the automatic water adding control circuit. The automatic water adding control system is not only simple in structure, but also low in cost; the water supply solenoid valve can be opened through the automatic water adding control circuit when the water in the humidifier is not sufficient enough, so that automatic water adding is realized, and fault and waste of electrical energy due to working of the humidifier under no water condition are prevented; and the system is suitable for wide application.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic water addition control system for a humidifier based on a voltage-stabilizing rectification and filtering circuit. Background technique [0002] Humidifiers are gradually favored by people because they can humidify indoor air, especially in winter when the weather is dry, and humidifiers have become an indispensable household appliance for many people. When using a humidifier, you need to add water to the humidifier. The humidifier will spray water into the air by spraying. As the humidifier continuously sprays water mist, the water in the humidifier will become less and less. When the water in the humidifier is sprayed out, the humidifier will no longer spray, so it cannot continue to humidify the indoor air. The currently used humidifier cannot automatically add water after the water is used up, so it often results in the situation that the humidifier is activated bu...
