Active intake mask

Abstract

The invention provides an active intake mask. The active intake mask comprises a mask body, and a filter and active intake assembly arranged on the mask body, wherein the mask body includes an elastic surface layer, a one-way exhaust layer and a replaceable liner arranged in the thickness direction in sequence from outside to inside; sealing rings are respectively arranged on the upper and lower two sides of the mask body, and are fixed in strip-shaped grooves formed between the one-way exhaust layer and the liner; and the filter and active intake assembly includes an outer shell, a base, and an activated carbon filter screen, a Haipa filter screen, a fan and an energy module arranged in the mask thickness direction in sequence from outside to inside. The mask realizes active intake of purified clean air through the filter and active intake assembly, realizes smooth exhaust of exhaled air through the one-way exhaust layer, and improves the user experience of wearers.

Description

technical field [0001] The invention relates to a mask, in particular to an active air intake mask. 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 PM2.5 index gradually becoming the focus of pub...

AI Technical Summary

Problems solved by technology

A mask mainly includes 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. The current patent applications and commercially available products do already exist. Some technical solutions with fans and turbofans, but the following problems have not been completely solved in the existing solutions: when people breathe, if the external pressure is greater than the pressure in the lungs, they will feel stuffy; after using the mask for many times, the inner wall will Bacteria are growing, so avoid inhaling into the body when you use it again, and the reuse rate is poor; when meeting the individual needs of users, it is often inconvenient to wear, and the filtering effect of the mask will be affected
