Automatic cleaning device of air purifier

Abstract

The invention discloses an automatic cleaning device of an air purifier. The device is used for cleaning a dust collection plate in the air purifier and comprises a support. The device is characterized in that the support is arranged on the side face of the dust collection plate, an annular transmission mechanism is arranged on the support, and comprises a power assembly and a conveying assembly,the conveying assembly is arranged on the power assembly in a sleeving manner, the power assembly drives the conveying assembly to rotate, a cleaning roller is fixed to the conveying assembly, the cleaning roller can rotate around the axis of the cleaning roller, the cleaning roller contacts the dust collection plate face of the dust collection plate, in the rotating process of the conveying assembly, and the conveying assembly drives the cleaning roller to clean the dust collection plate face of the dust collection plate in an online manner. When the air purifier works, the cleaning roller cleans the dust collection plate in real time, the phenomenon that due to dust stacking, the air purification effect is reduced is avoided, and due to non-water cleaning, the danger of power leaking ofthe dust collection plate is avoided.

Description

technical field [0001] The invention relates to an air purifier, in particular to a cleaning device for an electrostatic dust collecting plate in the air purifier. Background technique [0002] With the rapid development of industry, there are more and more pollutants in the air. People pay more and more attention to air quality issues, and more and more air purifiers are used. At present, there are two main air purification technologies: [0003] The traditional filtration method is passive adsorption filtration, that is, mechanical filtration. Air is sucked into the machine by a fan, and the air is filtered through a built-in filter. The quality of this type of fan filter and the placement of the machine will affect the purification effect, but the high The high-quality filter screen is not easy to clean and needs to be replaced regularly, resulting in a large waste, and the mechanical filtration method requires the high-speed rotation of the fan, which is prone to noise. ...

AI Technical Summary

Problems solved by technology

[0003] The traditional filtration method is passive adsorption filtration, that is, mechanical filtration. Air is sucked into the machine by a fan, and the air is filtered through a built-in filter. The quality of this type of fan filter and the placement of the machine will affect the purification effect, but the high The high-quality filter screen is not easy to clean and needs to be replaced regularly, resulting in a large waste, and the mechanical filter method requires high-speed rotation of the fan, which is prone to noise

[0004] A new type of existing filtering method is active filtering, that is, high-voltage electrostatic dust collection, which uses a high-voltage electrostatic field to ionize the gas, charges the dust particles in the air, and is then adsorbed to the surface of the different electrodes. This type of air purifier It can not only ensure the air volume but also absorb fine particles, and has a good filtering effect. However, due to the adsorption of dust and other pollutants on the electrode surface of this type of air purifier, the electric field strength will decrease. If it is not maintained in time, the purification effect will be greatly reduced.

[0005] The current solution to this problem is mainly to manually disassemble the electrode plate, and then manually clean the electrode plate, but the electrode plate is generally large and difficult to disassemble easily, and due to high-voltage discharge, there is also a certain degree of danger during disassembly

[0006] Chinese patent application CN201768623 and CN204084611 all disclose the cleaning device to the dust collection plate, two kinds of cleaning devices are all to be cleaned with water, all will first air purifier stop working when cleaning the dust collection plate, and two kinds of cleaning devices are The dust collection plate is not completely isolated and cleaned, and the water splashed during cleaning may have the risk of electric leakage in the high-voltage electrostatic field
