Description

Technical Field

[0001] The utility model relates to the technical field of air purification, more specifically to a plasma air disinfection and purification mask. Background Art

[0002] Air purifier, also known as "air cleaner", air freshener, or purifier, is a product that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air. It is mainly divided into household, commercial, industrial, and building types.

[0003] The filter technology of air purifiers mainly refers to the use of HEPA filters or activated carbon filters to filter pollutants in the air. However, both filters have their own advantages and disadvantages. The advantage of HEPA filters is that they are effective and safe, and are the most important technology for removing particulate pollutants from the air. However, the disadvantage is that they can only filter out suspended particles and cannot filter out harmful gases. In addition, the use of HEPA filters or activated carbon filters requires regular replacement of filters. Air purifiers using HEPA filters must have a good airtight design, otherwise the air will bypass the filter and lose the filtering effect. Activated carbon is a loose and porous substance. Its developed pore structure gives it a large surface area, so it can easily adsorb volatile organic macromolecules such as benzene and toluene. It also carries cold catalyst technology for the catalytic decomposition of toxic gases such as formaldehyde.

[0004] There are many types of air purifiers on the market. Most of them are large models and are basically used in homes, offices or factories. They purify the air in a certain space to meet the needs of people.

[0005] However, when people step outside these spaces or encounter low air quality, they can no longer meet their needs. Currently, people often resort to wearing masks, but these masks also have some drawbacks. Good air permeability means poor filtration, and vice versa. Existing disinfection and purification masks are bulky and heavy, making them uncomfortable to wear and unsightly in appearance. Summary of the Invention

[0031] One embodiment of the present invention is as follows:

[0032] A plasma air disinfection and purification mask includes a Y-shaped main body and a U-shaped split body. The main body and the split body are hingedly connected by a pin 10. The main body and the split body can rotate relative to each other around the pin 10 to adjust the angle; the pin 10 is located at the middle upper end of the main body, and the main body and the split body form a certain angle to form a wearing groove, which can accommodate the shoulders. This is also the wearing method of the purification mask recorded in this application. The purification mask is placed around the neck, which has good wearing stability and the weight of the entire purification mask can be evenly distributed, which will not cause discomfort to the wearer.

[0033] At the same time, a torsion spring is provided on the outside of the pin shaft 10, and the two straight torsion arms of the torsion spring are respectively against the main body and the split body. The main body is a Y-shaped structure, and the split body is a U-shaped structure. The split body is located on the inner side of the main body, and the middle part of the split body is against the middle part of the main body. It can be adjusted to a certain angle, and people of different body shapes can wear it comfortably.

[0034] The main body includes an end portion and two supporting legs connected to each other, and an air intake device connected end to end is provided inside the main body, which is used to allow gas to enter the main body through the air intake device and perform preliminary filtration on the gas;

[0035] The air intake device includes an air inlet 5, a filter 6, a primary filter 7 and a HEPA filter 8, which can filter out relatively large impurities, such as catkins and spider webs. The air inlet 5 is arranged on the back of the filter chamber 2, and a filter 6 is arranged on the inner side of the air inlet 5. A primary filter 7 and a HEPA filter 8 are arranged on the inner side of the filter 6. The primary filter 7 adopts a G4-level coarse filter 6 to effectively block large particles such as hair and fluff. The HEPA filter 8 adopts an H13-level high-efficiency filter 6 to effectively remove PM2.5 particles.

[0036] A bracket 4 is mounted within the filter chamber 2, upon which a plasma generator 3 is mounted. The plasma generator 3 comprises positive and negative plates spaced at a specific distance from each other. Both the positive and negative plates have a wavy structure. In this embodiment, the spacing between the positive and negative plates is 6 to 10 mm.

The electrode wires can generate the most appropriate electric field strength and can efficiently plasmatize the air around them to achieve a high level of purification and disinfection.

[0038] The plasma generator 3 can directly kill and remove most bacteria and viruses in the air through pulsed high voltage. At the same time, since the distance between the positive plate and the negative plate is very close, sufficient sterilization effect can be generated through a relatively low voltage without generating ozone.

[0039] There are two air intake turbofans 13, located at the junction of the end portion and the support leg portion, and the rotation speed can be adjusted separately through the control panel to change the air outlet speed and air outlet volume.

A plurality of through holes are provided on the main body shell, and the plurality of through holes are connected to the filling cavity 12. Perfume or air freshening liquid is dripped into the sponge layer through the through holes. The sponge can keep the perfume effective for a long time. Rubber plugs are provided on the through holes to prevent the perfume from leaking out.

[0041] An air outlet head 16 is provided at the end of the air duct cavity, and a plurality of air outlet holes 15 connected to the air duct cavity are provided on the air outlet head 16. The air outlet holes 15 on both sides are arranged facing each other, and the filtered and sterilized air is sprayed from the air outlet holes 15 to the mouth and nose of the personnel.

The battery is electrically connected to the control board, and the control board is electrically connected to the plasma generating device and the air intake turbofan 13.

[0043] A counterweight 9 is provided at the end to ensure uniform weight distribution between the front and back to prevent accidental falling when worn.

[0044] In order to ensure the utilization rate of purified air, an auxiliary mask is also included. The auxiliary mask can be worn on a person's face to completely cover the mouth and nose. The auxiliary mask includes a mask body 22. The rear end of the mask body 22 is provided with an elastic band for wearing on the head. It can also be replaced with an ear rope. Both sides of the mask body 22 are connected with a connecting valve 21. The connecting valve 21 is connected with an trachea. The other end of the trachea is connected with a connector 18 connected to the air outlet head 16. The connector 18 includes a through hole and a limiting device. The limiting device includes a limiting head 14 and a limiting groove 19. The limiting groove 19 is arranged at the end of the connecting head 18, and the limiting head 14 is arranged at the corresponding position of the air outlet head 16; the end of the limiting head 14 is provided with a flexible sphere, which is made of rubber and can pass through the limiting groove 19 with a relatively small diameter. The inside of the limiting groove 19 is provided with a ball groove adapted to the flexible sphere. After the flexible sphere and the ball groove are combined, they can play the role of limiting and stabilizing connection.
