Problems solved by technology

However, the patent does not elaborate on the configuration, filter material, and purification function of the air purifier.
Chinese utility model patent CN203329522U discloses a 360-degree air purifier. The air purifier is composed of several air purifiers. Although it can purify the air at 360 degrees, the structure is complex, the volume is large, and it takes up a lot of space.
Chinese utility model patent CN202740966 U discloses a box-type air purifier, which adopts a filter plate device, an atomization stirring device, and an air outlet device in the purifier box body to process and purify harmful gases in the air. Harmful gases in the air have a certain removal rate, but the removal effect on PM2.5 dust is poor

Abstract

The invention relates to a membrane air purifier. The membrane air purifier is cylindrical in the shape and composed of a control panel (1), an upper case (2), a middle case (3), a lower case (5) and a base (6). The control panel is arranged at the top of the air purifier. The upper case is provided with clean air outlets in the direction of 360 degrees. A round duct fan is arranged in the middle case. An air purification assembly is arranged in the lower case. The lower case is provided with air inlets in the direction of 360 degrees. The membrane air purifier can effectively filter PM2.5 in the air, can effectively prevent bacteria from breeding in the purifier to avoid the formation of secondary pollution, uses ultra-fine nano-photocatalysts material modified activated carbon as a VOC (Volatile Organic Compounds) purification component to effectively adsorb and decompose VOC under the action of a light source, is small in size and can achieve 360-degree air intake and clean air discharge so as to achieve multi-angle all-dimension air purification.

Description

technical field [0001] The invention relates to a membrane method air purifier, which can effectively remove PM2.5 and VOC in the air, has the function of sterilization and deodorization, and belongs to the field of air purification. [0002] technical background [0003] In recent years, with the development of social economy, the material consumption level of residents has been continuously improved. On the other hand, economic development has also brought pollution to people's living environment, especially the problem of PM2.5 air pollution, which has become more and more popular among people. attention. An air purifier is a product that can absorb, decompose or transform various air pollutants (generally including dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air. The ordinary filter screen used in the existing air purifier has low removal efficiency for PM2.5, which is easy to c...
