Problems solved by technology

[0006] 1) The external air is sent to the mask shell through the filter and the fan successively, and a one-way breathing valve needs to be installed to ensure that the external dirty air does not enter the shell through the exhaust port during inhalation, resulting in a decrease in the cleanliness of the inhalation
After setting the one-way breathing valve, the exhalation resistance will be greatly increased, and there will still be a sense of suffocation;
[0007] 2) The auxiliary purification system is not combined with the mask shell, which makes the volume and total amount of the mask larger, which affects the long-term wearing experience

Embodiment Construction

[0024] Such as figure 1 , figure 2 The shown embodiment 1 is an air-purifying nasal mask, which includes an electrostatic dust collection unit 1 , a breathing chamber 2 , an exhaust fan 3 , a sealing structure 4 and a wearing structure 5 . In addition to the parts shown in the figure, it also includes a battery, a control circuit board and a high-voltage power supply. The battery supplies power to the exhaust fan 3 and the high-voltage power supply.

[0025] Among them, the electrostatic dust collection unit 1 includes an airflow channel formed by the electrode pieces electrically connected to the two stages of the high-voltage power supply, which can absorb dust in the air when the airflow passes through.

[0026] The breathing chamber 2 can cover the nostrils and mouth of the human body. The breathing chamber 2 of the electrostatic dust collection unit 1 forms an integral structure. , the air outlet of the electrostatic dust collection unit 1 is the air inlet of the brea...

Abstract

The invention discloses an air-purifying nasal mask, which includes an electrostatic dust collection unit, a breathing chamber, an exhaust fan, and a wearing structure. The channel can absorb dust in the air when the airflow passes through; the breathing cavity covers the nostrils or forms a sealed channel with the nostrils. When the exhaust fan is working, a negative pressure area is formed in the breathing chamber, and the outside air is sucked into the breathing chamber through the electrostatic dust collection unit, so that the breathing chamber is filled with clean air. And due to the suction of the exhaust fan, the exhaled gas is sucked to the outside of the breathing chamber, so that the exhalation is smooth and there is no feeling of stuffiness, and the product is smaller in size and weight, and the wearing comfort is better.

Description

technical field [0001] The invention relates to the field of personal protective equipment. Background technique [0002] More and more studies have shown that air pollution, especially particulate matter such as PM2.5, is very harmful to human health. At present, there are many air purification products that can effectively improve and solve the problem of indoor air pollution. [0003] However, for outdoor activity scenes, or places without air purification facilities, there is currently no good air purification solution. [0004] The main body of a traditional medical or labor protection mask is composed of a single or multiple layers of filter cotton. The nose is actively inhaled to make the air pass through the filter cotton to filter dust and then enter the nasal cavity. The exhaled air is passed through the filter cotton or discharged through the gap between the mask and the face. Due to the need to balance the mask resistance and purification effect, it is difficul...
