Description

A graphene mask

technical field

The invention relates to the field of air filtration, in particular to a graphene mask.

Background technique

At present, smog weather is a common disastrous weather phenomenon in cities, and contains a large amount of fine particulate matter (PM2.5, etc.), which seriously affects human respiratory system and health. In order to reduce the impact of smog on human health, there are many kinds of PM2.5 masks suitable for outdoor wear.

The current PM2.5 masks are mainly filtered by HEPA (High Efficiency Air Filter) filters. The HEPA filter can effectively filter particulate matter such as PM2.5, PM1 and even PM0.3. However, the HEPA filter has a large wind resistance, which makes the wearer's breathing difficult, especially the sick, the elderly, and children are not suitable for wearing it. And the HEPA filter will be blocked by dust after long-term use, so the use cost is relatively high.

At present, there are masks made of graphene material, but the graphene material is integrated with the mask body and cannot be disassembled. If the mask body is dirty after a long time of use, the graphene material and the mask body can only be discarded together, which causes resource loss. waste.

In order to achieve the above object, the utility model provides a graphene mask, comprising a mask body and a hook connected to the mask body for hooking on the ear, characterized in that, the mask body is an arched structure, and the mask body The body includes an inner contact layer in contact with the wearer's skin and a surface layer in direct contact with the outside air. An air filter is provided at the mouth and nose of the wearer between the inner contact layer and the surface layer, and the air filter includes fiber in turn. Surface layer, melt-blown non-woven fabric layer, graphene and chitosan mixed layer and fiber surface layer; On the mouth mask body, the wearer's mouth and nose are provided with openings, and the air filter can be removed from the mouth mask body through the openings. Insert or pull out between the inner contact layer and the surface layer.

Preferably, the melt-blown non-woven fabric layer is subjected to electret treatment to be permanently charged with static electricity.

Preferably, the opening is provided with adhesive strips corresponding to each other to seal the opening.

Preferably, the outer edge of the mask body is provided with hydrogel.

Preferably, the mask body is made of flax fiber fabric.

Compared with the prior art, the utility model has the advantages and beneficial effects of:

By setting the air filter sheet at the wearer's mouth and nose between the inner contact layer and the surface layer of the mask body, and the air filter sheet is provided with a fiber surface layer, a melt-blown non-woven fabric layer, a graphene and chitosan mixed layer And the fiber surface layer, which can filter the bacteria in the air layer by layer, the graphene material has stronger adsorption capacity, chitosan can be antibacterial and antibacterial, and the melt blown non-woven fabric layer is treated with electret, which can be permanently charged with static electricity and can be more effective Adsorb PM2.5; by setting openings on the mask body corresponding to the wearer's mouth and nose, the air filter can be inserted or pulled out from the inner contact layer and the surface layer of the mask body through the opening, avoiding any contamination of the mask body. When the stain is difficult to clean, the air filter and the mask body are discarded together, saving resources.
