Description

High-airtightness anti-infection mask

Technical Field

The invention relates to the technical field of masks, in particular to an anti-infection mask with high air tightness.

Background

The mask is widely used in various medical occasions as the most common medical care product, and the core function of the mask is to filter the air inhaled by a user so as to reduce or prevent dust, germs, viruses and the like from entering the inside of a human body.

Although the mask can filter virus, germs and dust in the air when in use, and is beneficial for a user to inhale clean air, the mask is a serious pollution source for the replaced mask because more dust and virus and germs are left on the mask after use.

In order to solve this problem, the conventional treatment method is to uniformly recover the replaced mask and then perform uniform aseptic treatment.

However, in the actual use process, there are still disadvantages, for example, after the mask is replaced, if there is no professional mask recovery point around the user, the user can only fold the mask to store it, and then put it into the recovery device when meeting the recovery point; in the process, the hands and the pockets for containing are very easy to be polluted by dust and virus and germs on the mask, especially for high-infectivity virus and germs, the mode is very easy to cause infection, and the mode is also the important problem that the infection still exists at present under the condition of using the mask in a large range;

further, even at the same mask recovery point, the recovery device is usually an open structure such as a trash can in order to facilitate the recovery work. The used mask is discarded in the recovery device in an unfolded state, virus and bacteria on the mask are also easy to volatilize to a nearby space, particularly, a large amount of water vapor is usually present on the used mask, and a large amount of masks are gathered and then are nearby the recovery device, particularly, the inside of the recovery device is easy to volatilize to form aerogel.

Disclosure of Invention

The invention aims to: aiming at the defect that the existing mask is easy to form an infection source after being discarded, the high-air-tightness anti-infection mask capable of reducing the risk of the infection source formed by the replaced mask is provided.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides an anti-infection mask of high gas tightness, includes the cover body and ear area, be provided with the ear area on the cover body still be provided with the winding assembly on the cover body, the winding assembly is used for coiling the cover body. In the scheme of the application, the winding assembly winds the cover body, and the cover body is wound on the winding assembly layer by layer. Adopt the anti-infection mask of this application, after finishing using, the user is with the cover body coiling of winding assembly for the cover body is convoluteed to the less state of tightening up of volume, such mode, on the one hand has reduced the volume by a wide margin, more does benefit to the collection of abandonment mask, and more importantly, compare in the cover body that is the form of expanding, should convolute into the cover body of less volume, the dust and the virus bacterium of adnexed on it are more difficult to get into in the air, so, the risk of polluting space around has been reduced, just also reduced the risk that appears the infection.
