Control system for air purifier

Abstract

A control system for an air purifier comprises a single-chip microcomputer, a humidifier, a buzzer, a lamp tube driving circuit, an ultraviolet lamp, a frequency converter, an alternating current motor, an infrared remote control, a humidity sensor, an air quality sensor, an infrared sensor, an LCD display screen, a key and a direct current power supply. The humidifier and the buzzer are respectively connected with the single-chip microcomputer. The infrared remote control, the lamp tube driving circuit and the frequency converter are respectively connected with the single-chip microcomputer. The ultraviolet lamp is connected with the lamp tube driving circuit, and the alternating current motor is connected with the frequency converter. The humidity sensor, the air quality sensor, the infrared sensor and the key are respectively connected with the single-chip microcomputer, the LCD display screen is connected with the single-chip microcomputer, and 220V alternating current is supplied to the frequency converter and the ultraviolet lamp and is supplied to the single-chip microcomputer after being converted through the direct current power supply. The control system can monitor indoor air quality conditions in real time and have response sensitivity, is provided with a friendly human-computer interaction interface and has functions of automatic startup and shutdown, selection of various working modes and various operation modes.

Description

technical field [0001] The invention relates to the field of electrical devices, in particular to a control system of an air purifier. Background technique [0002] With the improvement of human living standards, people have higher and higher requirements for the air quality of the living environment. At present, the air dust and bacteria in residents' living and office places generally exceed the standard. Most of the existing air purification methods use drugs or reflective methods. Such purification methods have brought many side effects, and the dust and bacteria still cannot be completely eliminated. . Also have some to adopt fan purifier to carry out air purification, and air purifier is made up of blower fan and filter screen, and air enters from air inlet and passes through filter screen and is discharged from air outlet, and larger dust is filtered out by filter screen. Its disadvantage is that very fine dust cannot be filtered out and it does not have the effect ...

AI Technical Summary

Problems solved by technology

The disadvantage is that very fine dust can not be filtered out and can not achieve the effect of sterilization

Existing air purifiers have complex structures but single functions, which cannot meet people's needs. Therefore, a new technical solution should be provided to solve the above problems
