Abstract

The invention relates to a dehumidifying self-heating activated alumina three-dimensional mask, which belongs to the technical field of bacteria prevention for daily necessities. The dehumidification self-heating active alumina three-dimensional mask of the present invention comprises a cover body and ear hooks, and the cover body comprises a cover body frame, a non-woven outer layer, an activated alumina absorbent cotton gauze layer, a chitosan absorbent cotton gauze layer and a non-woven inner layer , the outer layer of non-woven fabric, the layer of activated alumina absorbent cotton gauze, the layer of chitosan absorbent cotton gauze and the inner layer of non-woven fabric are sequentially stacked and arranged in the cover frame. The active alumina degreased cotton gauze layer in the mask of the present invention will generate heat after absorbing water, and chitosan has significant adsorption capacity and good antibacterial properties, and can not only effectively isolate and absorb suspended particles and harmful gases in the atmosphere during winter wearing, And it can dry the moisture remaining on the mask due to the temperature difference in winter and heat it up to keep warm, play the role of a breathing valve, effectively prevent the growth of bacteria in the mask, and play a protective role of antibacterial and sterilizing.

Description

technical field [0001] The invention relates to a dehumidifying self-heating activated alumina three-dimensional mask, which belongs to the field of antibacterial technology for daily necessities. Background technique [0002] Masks are more and more widely used in people's lives, because they have a certain filtering effect on the air entering the lungs. When working in an environment polluted by respiratory infectious diseases and dust, wearing a mask has a very good effect, which can prevent The invasion of bacteria and dust to the human body. Ordinary masks only have general filtering functions, and the functions are relatively single. In the process of using the mask, especially in winter, the mask will also be wet due to respiration, allowing bacteria and microorganisms to grow on it. Contents of the invention [0003] The present invention aims at the problems existing in the prior art, and provides a dehumidifying self-heating activated alumina three-dimensional ...
