Portable air purification kit adopting active air feeding

Abstract

The invention provides a portable air purification kit adopting active air feeding. The portable air purification kit comprises a purifier main unit and a mask, wherein the purifier main unit is used for filtering and purifying ambient air and outputting clean air; the output clean air is delivered to the mask through an air guide pipe and supplied to a mask wearer for inhaling; a check valve is arranged on the mask and used for exhausting gas exhaled by the mask wearer. According to the portable air purification kit, active feeding of the purified clean air for the mask wearer is realized by changing the working state of a turbofan, and a suffocating feeling of the wearer is avoided effectively.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a portable active intake air purification kit. Background technique [0002] Fine particulate matter, also known as PM2.5, refers to particulate matter in the ambient air with an aerodynamic equivalent diameter of less than or equal to 2.5 microns. Particles with a diameter of 10 μm are usually deposited in the upper respiratory tract, and those below 2 μm can penetrate deep into the bronchioles and alveoli. After fine particles enter the human body to the alveoli, they directly affect the ventilation function of the lungs, making the body prone to hypoxia. Compared with coarser atmospheric particles, PM2.5 is harmful to human health due to its small particle size, large area, strong activity, easy to attach toxic and harmful substances, and its long residence time in the atmosphere and long transportation distance. and air quality have a greater impact on [0003] With the PM2....

Problems solved by technology

Masks mainly include functional units such as air filtration, sealing, and wearing. There are many masks with anti-fog and haze functions on the market that have air valves and multiple filters. In the patent search, there are some with fans, vortex However, the following problems have not been completely solved in the existing solutions: when a person breathes, if the external pressure is greater than the pressure in the lungs, he will feel stuffy; after using the mask many times, bacteria will grow on the inner wall, and the mask will be used again. It is necessary to avoid inhalation into the body, and the reuse rate is poor; while satisfying the diversification of appearance and structure, the filtering effect of the mask will be affected, and the battery life of the mask with power supply is short

[0004] Therefore, the large air inhalation and exhalation resistance, poor filtering effect and low reusability are the deficiencies that are common in current masks and need to be improved urgently.
