Description

Wearing equipment based on filtration

Technical Field

The invention provides a wearable device based on air filtration, in particular to a wearable device which removes unfiltered air outside the nose of a user by positive pressure flowing air after air is filtered so as to improve the protection effect during breathing and ensure the privacy and the aesthetic property.

Background

According to the fact that the global air pollution is more and more serious as more countries enter industrialized development, the latest global air quality report shows that people with the land area of nearly 9 days in the world cover pollution factors such as fine suspended particles (PM2.5) for a long time, and about 420 thousands of people die of the pollution factors, the obvious air pollution problem seriously influences the life and health of people.

Among them, suspended particles or Particulate Matter (PM), Atmospheric particulate matter (Atmospheric particulate matter), particles (particulate), generally refer to solid particles or liquid droplets suspended in air, and the particles are tiny and even difficult to be identified by naked eyes but have a certain size difference; in environmental science, excessive particle dispersion and suspension caused by human activities are one of the main indicators of air pollution, but can cause organism discomfort or influence ecology and energy cycle range coverage scale is wide, including water mist, dust, pollen, scurf, allergen and haze; artificially discharging waste gas, spraying pesticides, fertilizers and wastes such as feces of livestock raising wind and raising dust, and the like until the precursors form sulfate, nitrate and ammonium salt after a series of extremely complex chemical changes and photochemical reactions in the atmospheric environment; wherein, particulate matter having an aerodynamic diameter (hereinafter referred to as a diameter) of 10 micrometers (μm) or less is referred to as inhalable particulate matter (PM 10); particulate matter having a diameter of less than or equal to 2.5 microns is known as fine particulate matter (PM2.5), such as second hand smoke in a room; particulate matter can stay in the atmosphere for a long time and can enter the body with breathing, accumulate in the trachea or lungs and affect the health.

In order to prevent the suspended particles in the air, or possible flying foam and germs from being inhaled into the mouth and nose of a user, most people are used to wear the mask when going out, especially when riding a locomotive or a bicycle, in public places with dense people or in areas with serious haze, so that the inhalation of substances harmful to human bodies is avoided, and the probability of disease infection is effectively reduced.

The ability of filtering harmful substances in the air by wearing the mask is very limited, and the particle size of PM2.5 suspended particles is very small, so the mask which is usually worn cannot be filtered, and a special mask with high density and air gap smaller than 2.5 microns is required to be filtered, and the mask cannot really and completely shield the mouth and nose when worn, so the external air still has the worry that the external air directly invades the mouth and nose of a user through the gap between the mask and the face without passing through the mask; moreover, the filtering protection ability of the mask is inversely proportional to the breathing impedance, so that the mask with higher protection ability increases the difficulty of breathing of the user, and is not suitable for being worn for a long time, and on the contrary, the mask easy to breathe has lower filtering degree, so that the protection effect cannot be really achieved;

in addition, since the mask is attached to the face of the user when worn, modern people pay more attention to the door, amenity and health, and therefore cosmetics or health care products are often applied to the face, and if the mask is worn at the same time, the cosmetics or health care products are stained on the mask lining, so that the cosmetics or health care products are removed, and the makeup of the user is affected.

In order to achieve a good filtering and protecting effect and improve the breathing comfort of the user, the conventional air purifying system for providing electric air supply is mainly provided with the following types:

1. a special mask for wearing and an air supply fan assembly capable of filtering PM2.5 suspended particles are adopted to provide clean air. The mask is connected with a hose so as to be connected with an air supply fan assembly, and the positions of the air supply fan assembly are different.

2. The special mask which is worn and the air supply fan component which can filter PM2.5 suspended particles are adopted, and the air supply fan component which can filter PM2.5 suspended particles is directly arranged on the mask.

3. The special mask is additionally provided with a one-way valve.

4. Negative ion type without mask and positive blowing type.

But with the following disadvantages:

1. the mask is of a special structure, and replacement is not easy to be relatively high compared with the price which needs to be paid.

2. The mask which needs to be connected with a hose so as to be connected with the air supply fan assembly needs to bear the weight of the whole hose; when the mask is worn, the force of the mask on the face needs to be large, the mask is uncomfortable to wear, and cosmetics or care products are stained on the inner lining of the mask, so that the cosmetics or the care products can be removed.

3. The air supply fan component is directly arranged on the mask, on one hand, the noise is hard to endure because the fan is too close to the ears, and on the other hand, the weight of the air supply fan component also makes the force of the mask on the face larger when the mask is worn, which also affects the beauty when the mask is worn.

4. When wearing the mask, the mask must completely cover the mouth and nose to prevent the outside air from directly permeating into the gap between the mask and the face without being filtered by the mask.

5. When the air supply fan assembly is used for supplying air to the inlet cover, the air stop part is not arranged, the air of the air supply fan assembly directly impacts the nostrils and the skin of the face of a user, and the breathing and the comfort of the user are influenced.

6. The air supply fan assembly is arranged on the cap body, so that the whole weight of the cap body is too heavy, and the fan is arranged on the cap body, so that the noise is hard to endure because the fan is too close to the ears.

7. The negative ion type or positive blowing type without a mask is not suitable for the outdoor with air flow.

8. Uncomfortable to wear and unattractive.

In view of the above, the inventors have made an effort to further research, develop and improve a portable air cleaning device, and have made the present invention after repeated experiments and modifications with a preferred configuration to solve the above problems.
