Mask

Abstract

The invention discloses a mask. The mask comprises a wearing device, wherein a power assisting device is arranged at a left end of the wearing device; through cooperation of a strain device, a switching device and a clamping device, people can adjust the starting time point and power of the power assisting device according to own breathing habits, it is ensured that a wearer can breathe in a more comfortable mode, breathing is smooth, airflow assisting force provided by the assisting device can be completely used for overcoming airflow resistance brought by the mask, various adverse effects brought by positive pressure ventilation are avoided, people can adjust the position height of the sealing device through the adjusting device, applicability is further improved, through the sealing device, nose breathing and mouth breathing are carried out separately, the influence area of exhaled wet and hot air on the face skin can be effectively reduced, people can replace the protective face body conveniently through the protective device, and practicability of the mask is improved.

Description

technical field [0001] The invention relates to the field of masks, more specifically, to a mask. Background technique [0002] The mask is mainly composed of a protective surface and a tension belt. The protective surface is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric, and the middle layer is single or multi-layer ultrafine polypropylene fiber melt-blown material. The outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer, which has a good fit with the wearer's face, can filter particles in the air, and block pollutants such as droplets, blood, body fluids, secretions, etc. The filtration efficiency of non-oily particles can reach more than 95%. It is a personal protective equipment commonly used to deal with airborne diseases. The existing masks have good airtightness and poor permeability. People are prone to breathing difficulties when wearing masks In particular, patie...

Problems solved by technology

[0005] Aiming at the existing masks with fans in the prior art, people will be in a positive pressure ventilation environment for a long time after wearing them. Complications such as pneumothorax or pneumomediastinum reduce cardiac return, which may lead to hypotension, and easily cause adverse reactions such as dry throat, dry nose, and epistaxis, which seriously endanger people's health. At the same time, nasal breathing and mouth breathing are completely Sharing the airflow circulation air path, this will make the skin near the nose and the skin near the mouth be in a humid and hot environment for a long time, which will easily cause various skin diseases. The purpose of the present invention is to provide a mask, which can be well Solve the problems raised in the background technology
