Description

Air purifier capable of cleaning filter screen

Technical Field

The utility model relates to an air purifier technique, concretely relates to air purifier of cleanable filter screen of intelligence.

Background

An air purifier is also called as an air cleaner, an air freshener and a purifier, and is a product capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde and other decoration pollutants, bacteria, allergens and the like) and effectively improving the air cleanliness. Along with the rapid development of modern industrial technology, air pollution is more and more serious, more and more families also use air purifiers, the air purifiers mainly comprise a motor, a fan, an air filter screen and other systems, the HEPA filter screen is a core purification consumable part of the air purifiers, the HEPA filter screen mainly adsorbs small-particle dust, if excessive large-particle-size dust, hair, scurf, winged insects and other impurities are adsorbed, the wind resistance of the purifiers and the adsorption effect of the filters are increased, and the early end service life is reached, if the HEPA filter can be enabled to exert the performance of extremely adsorbing dust particles in small and micro air, the large-particle-size dust and the impurities can be preferably removed in time.

Most air purifier do not possess the function of clean filter screen at present, need the manual work to tear the filter screen down and wash usually, and the clearance is more troublesome. In view of the above circumstances, cleaner manufacturers sometimes also recommend users to use a dust collector to remove the large-particle-size impurities on the HEPA at times, but the chinese families are not always equipped with a dust collector, and a household dust collector cannot be attached to a filter if no small dust collection opening is provided, so that the vacuum degree of the dust collector cannot be maintained, and the adsorption effect is limited.

According to the investigation, the traditional Chinese patent CN201820471308 intelligent air purifier with an automatic cleaning filter screen comprises a device main body, a motor, an exhaust fan, a support, a water tank, a control panel, wheels, an air inlet tank, a filter screen, an air outlet and a pipeline, wherein the support is fixedly connected to the bottom end of the right side of the device main body, and the motor is arranged on the surface of the top end of the support in a nested manner. This kind of air purifier distributes in the device main part has two rows of blowing pipes for blow off the impurity of leaving over on the filter screen. But the adsorption effect on the dust is not ideal, and only the dust on the surface can be removed.

Also, chinese patent No. CN201710476356 is "a self-cleaning air purifier", the self-cleaning air purifier includes a housing, a fan, a detachable filter element and a self-cleaning filter screen device, a cavity is provided in the housing, the two ends of the housing are connected by the cavity, the housing is of a rectangular structure, the self-cleaning filter screen device is installed at one end of the cavity of the housing, a cross-arm frame is provided at the other end of the cavity, the fan is provided at the center of the frame, a square through hole is provided on the upper surface of the housing, the square through hole is communicated to the cavity, and the detachable filter element is installed in the square through hole. The purifier is provided with a self-cleaning filter screen device, can realize the automatic cleaning of the filter screen, but has more complex structure, more parts and higher cost.
