Description

Portable Air Purifier

technical field

The utility model discloses a portable air purification device, which belongs to the field of air purification equipment manufacturing.

Background technique

With the process of industrialization, environmental pollution has intensified, and the air quality has also deteriorated. According to the reported data, the PM2.5 value in major cities has a tendency to increase year by year, so energy conservation and environmental protection are particularly important. However, it is unrealistic to achieve a significant improvement in air quality in a short period of time. Therefore, it is necessary to develop some air purification devices to improve the air quality in limited spaces. Now some indoor air purification equipment is more common on the market, generally using HEPA Filters, fiber filters, photocatalytic technology, negative ion technology or high-voltage electrostatic technology can purify the gas in the closed environment. When people are outdoors, in addition to using some dust masks, there are few effective reusable air purification devices on the market at present. Of course, some people are already trying to develop some portable air purification devices. For example, the utility model patent 201320880092.8 discloses a portable air purification respirator, which is mainly composed of a turbo blower and a three-layer composite filter. It is similar to the traditional dust mask, but there are still the following problems: due to the lack of convenient air quality testing equipment, it is impossible to determine when the composite filter needs to be updated; if the composite filter cannot be updated in time, it is easy to breed microorganisms on the filter, resulting in secondary pollution; on the other hand, the renewal of the composite filter is also a considerable expense. Utility model patent 201420072905.5 discloses a portable air purifier that uses a filter set, ultraviolet lamp, air pump, negative ion generator, etc. to filter air. The utility model has the following problems: the design is too complicated, the design cost and maintenance cost are high, and the problem of when to replace the filter element group still cannot be solved; the sterilizing effect of the ultraviolet lamp also needs further verification when the air flow rate is fast. Due to the above problems in the prior art, it is necessary to explore a more convenient and practical portable air cleaning device.
