Household air purifier

Abstract

The invention discloses a household air purifier which comprises an air purifier body, and a strain device is arranged in the air purifier body. The surface of an air filter element and the inner wall of a protective shell are automatically brushed through cooperation of a brushing device, a transmission device and a release device, so that particulate matters left on the surface of the air filter element and particulate matters attached to the inner wall of the protective shell are removed, the situation that air holes in the air filter element cannot be blocked is ensured, air resistance is small, energy consumption is low, the air purifier is good in air purification efficiency, cleaned particulate matters are collected through a collecting device and weighed, the collected particulate matters are monitored through cooperation of the air purifier body, the strain device and the collecting device, people can clean the particulate matters in time under the condition that the collected particulate matters are large in number, later maintenance work is simple and convenient, moreover, time and labor are saved, and the practicability of the household air purifier is improved.

Description

technical field [0001] The invention relates to the field of air purifiers, more specifically, to a household air purifier. Background technique [0002] Air purifiers, also known as air cleaners, air fresheners, and purifiers, refer to products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness. They are mainly divided into household, commercial, industrial, and building. The main function of household air purifiers is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of air pollution caused by decoration or other reasons caused by indoor, underground spaces, and volatile organic compounds in cars. , the existing household air purifier is mainly composed of a chassis shell, a filter element, a motor, a fan, a power supply, and a liquid crystal display screen. Its working principle is that the motor and fan in the machine circulate the indoor air, and the pol...

AI Technical Summary

Problems solved by technology

[0005] For existing domestic air purifiers in the prior art, particles will gradually adhere to the surface of the filter element during long-term use, and these particle attachments will accumulate layers on the surface of the filter element, which will block the air holes on the filter element , resulting in increased air resistance, increased energy consumption, and reduced air purification efficiency. In order to solve this problem, people need to frequently disassemble the filter element and clean up the particles attached to its surface, resulting in extremely heavy post-maintenance work, and every time Maintenance is extremely time-consuming and labor-intensive. The purpose of the present invention is to provide a household air purifier, which can well solve the problems raised in the background technology
