Description

air purifier

technical field

The utility model belongs to the technical field of air purification, in particular to an air purifier.

Background technique

Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust and haze removal, harmful decoration residues and peculiar smells, so as to improve living and office conditions and improve physical and mental health. Indoor environmental pollutants and pollution sources mainly include volatile organic gases, mold, pollen, particulate matter, decoration residues, second-hand smoke, etc.

As a new type of electrical appliance, air purifiers have entered the household field, which can reduce indoor air pollution and remove harmful substances in the air. Among them, the filter plays a vital role. Existing filter screens usually adopt HEPA filter screens, activated carbon filter screens, and the like. This filter has a single function, and its filtering effect is slightly poor. Moreover, most of the existing filter screens are flat plate structures, and the filtering area is small.

Utility model content

The purpose of the utility model is to provide an air purifier, which has a compact structure, can increase the effective filtering area, and has a good purification effect.

In order to achieve the above object, an air purifier of the present utility model includes a housing, a composite filter screen and a fan arranged in the housing, the housing is provided with an air inlet and an air outlet, and the housing is a cylindrical structure. The composite filter includes a filter body, the filter body is an annular structure, and the filter body includes a primary filter, a HEPA filter, an activated carbon filter, and a fullerene fiber net that are sequentially arranged from outside to inside. , prepared carbon fiber net and photocatalyst fiber net, described activated carbon filter screen is made of coconut shell activated carbon, and described fullerene fiber net is made of fullerene nanofiber, and described prepared long charcoal fiber net is made of prepared long charcoal fiber, and the photocatalyst fiber web is made of activated carbon fiber loaded nano-titanium dioxide;

The air purifier also includes an ultraviolet lamp and a humidifying device, the ultraviolet lamp is arranged in the composite filter, and the humidifying device is arranged between the composite filter and the fan.

In order to fix the primary effect filter screen, HEPA filter screen, activated carbon filter screen, fullerene fiber net, binchotan fiber net and photocatalyst fiber net, the upper and lower sides of the filter screen body are provided with filter frames.

The filter frame includes an inner fixed plate and an outer cover plate, and a handle is arranged on the fixed plate.

The composite filter of the utility model adopts a ring structure, which changes the shape of the flat filter and increases the area of the filter, thereby increasing the effective filtering area of the air purifier, effectively reducing wind resistance, and improving the fluidity of the internal circulation; It adopts primary effect filter, HEPA filter, activated carbon filter, fullerene fiber net, binchotan fiber net and photocatalyst fiber net, combining six kinds of filtration technologies in one, and the filtering effect is good; a humidifying device is added to realize "purification" + Humidification" effect.
