Description

Wearable devices based on air filtration

technical field

The present invention provides a wearable device based on air filtration, especially a kind of air filter, which uses the air flowing under positive pressure to exclude the unfiltered air outside the user's nose, so as to improve the protective function during breathing. The effect does not make a privacy and aesthetics.

Background technique

By the way, as more and more countries enter into industrialization, global air pollution is becoming more and more serious. The latest global air quality report shows that nearly 90% of the world's land area is covered by pollution factors such as fine suspended particles (PM2.5) for a long time. , and about 4.2 million people died of this cause, the obvious air pollution problem seriously affects people's life and health.

Among them, suspended particles, or particulate matter (particulate matter (PM)), atmospheric particulate matter (Atmospheric particulate matter), particles (particulates), generally refer to solid particles or liquid droplets suspended in the air. The difference in scale; in environmental science, the excessive particle dispersion and suspension caused by human activities is one of the main indicators of air pollution, but it may cause discomfort to organisms or affect ecology and energy cycle. , pollen, dander, allergens, smog; man-made exhaust gas, spraying of pesticides, fertilizers, and wastes such as livestock manure in the wind and dust, etc., until the precursors undergo a series of extremely complex chemical changes and light in the atmospheric environment. Sulfates, nitrates and ammonium salts are formed after chemical reaction; Among them, particles with an aerodynamic diameter (hereinafter referred to as diameter) less than or equal to 10 microns (μm) are called inhalable particulate matter (PM10); PM10 with a diameter of less than or equal to 2.5 microns Particulate matter is called fine particulate matter (PM2.5), such as indoor second-hand smoke; 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 health.

In order to prevent the above-mentioned suspended particles in the air, or possible droplets and germs from being inhaled by users, most people now go out, especially when riding motorcycles or bicycles, in crowded public places, or When you are in an area with severe haze, you are used to wearing a mask to avoid inhaling substances that are harmful to the human body, and can effectively reduce the probability of disease transmission.

The ability of wearing a mask to filter harmful substances in the air is extremely limited, and because the particle size of PM 2.5 suspended particles is extremely small, the masks that are usually worn cannot be filtered, and masks with high density and an air gap less than 2.5 microns are required Only special masks can be filtered, not to mention that masks cannot completely cover the mouth and nose when worn, so there is still the possibility that the outside air will directly invade the user's mouth and nose through the gap between the mask and the face without passing through the mask; The filtering protection ability is inversely proportional to its respiratory impedance. Therefore, a mask with higher protection ability will increase the difficulty of breathing for the user, so it is not suitable for wearing for a long time. On the contrary, a mask that is easy to breathe has a lower degree of filtration. Low, so the protective effect cannot be achieved;

In addition, because the mask will fit the user's face when worn, and modern people pay more attention to appearance, etiquette and health, so cosmetics or skin care products are often rubbed on the face. If the mask is worn at the same time, it will cause cosmetics Or skin care products are contaminated on the inner lining of the mask, causing the cosmetics or skin care products to come off and affect the makeup of the user. In addition, most users are not used to or uncomfortable due to the contact between the mask and the skin.

In order to take into account the good filter protection effect and improve the user's breathing comfort, it is known to provide products and patents for the clean air system with electric air supply, which mainly include the following types:

1. Use a special mask to wear, and an air supply fan assembly that can filter PM 2.5 suspended particles to provide clean air. Hoses are attached to the mask to interface with the air supply fan assembly, which is placed in various locations.

2. Use a special mask to wear, and an air supply fan assembly that can filter PM 2.5 suspended particles. The air supply fan assembly that can filter PM 2.5 suspended particles is directly installed on the mask.

3. Add a one-way valve to the special mask worn.

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

However, it has the following deficiencies:

1. The mask used is a mask with a special structure, it is not easy to replace and the price that must be paid is relatively high.

2. The mask that needs to be connected with a hose to connect with the air supply fan assembly must bear the weight of the entire hose; when wearing it, the force of the mask on the face must be large, which is uncomfortable to wear and causes cosmetics Or skin care products are contaminated on the inner lining of the mask, making cosmetics or skin care products take off.

3. The air supply fan assembly is directly installed on the mask. On the one hand, the noise is unbearable because the fan is too close to the ear, and the weight of the air supply fan assembly also makes it harder to put the mask on the face when wearing it. If it is too large, it will also affect the aesthetics when wearing it.

4. When wearing a mask, it is also necessary to completely cover the mouth and nose, so as to prevent the outside air from directly infiltrating through the gap between the mask and the face without being filtered by the mask.

5. When the air supply fan assembly supplies air into the mask, there is no air stopper, and the air will directly hit the user's nostrils and facial skin, which will affect the user's breathing and comfort.

6. Installing the air supply fan assembly on the cap body will make the overall weight of the cap body too heavy, and because the fan is installed on the cap body and the fan is too close to the ear, the noise is unbearable.

7. Negative ion type without mask or positive blowing type are not suitable for outdoors with airflow.

8. Uncomfortable and unsightly to wear.
