The invention relates to a mask structure and a production method thereof. The mask structure comprises a mask part and a filtering assembly installed on the mask part, wherein the mask part is provided with an air suction port and an air inlet, the filtering assembly comprises a connecting sleeve, and one opening of the connecting sleeve is seamlessly and fixedly connected with the edge of the air inlet; the filtering assembly further comprises two filtering plates fixed in the connecting sleeve, the filtering plates and the inner wall of the connecting sleeve are in seamless sealing, filtering holes are formed in the filtering plates, the filtering assembly further comprises a filtering cylinder fixed between the two filtering plates, and openings are formed in the two ends of the filtering cylinder; two ends of each filter cartridge are respectively seamlessly sealed and fixed with the edges of the two filter holes of the different filter plates; the filtering assembly further comprises a rotating plate rotationally connected into the connecting sleeve, matching holes capable of corresponding to the different filtering holes along with rotation of the rotating plate are formed in the rotating plate, and the rotating plate and the inner wall of the connecting sleeve are in seamless sealing. According to the mask, different filtering functions of the mask can be achieved.
Description
technical field [0001] The present application relates to the technical field of masks, in particular to a mask structure and a production method thereof. Background technique [0002] A mask is a kind of hygiene product, which generally refers to wearing on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper and other materials. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0003] Ordinary disposable medical masks are simple in structure and are disposable for users. For example, a mask disclosed in the patent document CN211185967U includes a cover body, and the cover body includes a surface layer, a bactericidal layer, a filter layer and a skin-friendly layer. The surface layer, the bacte...
