Bionic temperature control and dehumidification mask

Abstract

The invention discloses a bionic temperature control and dehumidification mask, which belongs to the technical field of medical protective masks. The bionic temperature control and dehumidification mask comprises a common medical mask, a gasket, a heat preservation and insulation coating and a Tesla valve group; the bacterium filtering effect of the common medical mask is larger than or equal to 95%; the gasket is arranged in the common medical mask; the bionic heat preservation and insulation coating and the Tesla valve group are arranged on the gasket; and the material of the heat preservation and insulation coating is imitated polar bear hair. The bionic temperature control and dehumidification mask is based on the common medical mask and has a good protection performance; by arranging the bionic heat preservation and insulation coating imitating the polar bear hair, the temperature of the inner side of the mask is regulated and controlled, and expired air is prevented from being liquefied; the adopted gasket prolongs the cooling time of the expired air by using the physical principle, which reduces water vapor liquefaction and fundamentally reduces the occurrence of the situation that water is generated the inner side; meanwhile, water absorption substances are added, so that the dryness of the inner side of the mask is further guaranteed; and moreover, the one-way circulation of the Tesla valve is ingeniously utilized, so that the sucked air is not influenced by the added Tesla valve.

Description

technical field [0001] The invention relates to the technical field of medical protective masks, in particular to a bionic temperature-controlling and dehumidifying mask. Background technique [0002] The filter layer of the commonly used masks is generally three layers of non-woven fabric, the inner layer is anti-stick non-woven fabric, which fits the skin to make it comfortable to wear, and has a certain hygroscopic effect. The middle layer is melt-blown polypropylene non-woven fabric, which is The core component plays the main role of filter protection, and the outer layer is anti-stick non-woven fabric, which has a water-blocking effect, can prevent droplets, and filter larger particles. However, the anti-sticking nonwoven fabric of the inner layer does not have the ability to regulate the temperature of the airflow, so that it cannot produce a good moisture absorption effect when used in cold weather conditions, causing the water vapor inside the mask to liquefy and pro...
