Nasal mask device and nasal mask combined filter

Abstract

The invention provides a nasal mask device. The nasal mask device comprises nostril pipes, breathing cavities and an exhaust portion and involves a filter wearing method. The breathing cavities are communicated with the nostril pipes respectively. A one-way air inlet valve is arranged at the air inlet of each breathing cavity. A one-way exhaust valve is arranged at the air outlet of the exhaust portion. The nasal mask device further comprises nostril rubber sleeves and an adjustment portion arranged between the two breathing cavities. The nostril rubber sleeves are arranged at the ends of the nostril pipes. The adjustment portion is inserted into the breathing cavities in a penetrating mode and connected with the breathing cavities in an airtight mode through soft sealing rings. The nasal mask device is attractive in appearance and not prone to falling when worn, the nose distance can be freely adjusted according to the sizes of noses of people, and people can be prevented from injuries caused when people fall and the nostril pipes go deep into nostrils.

Description

technical field [0001] The invention relates to the technical field of respiratory equipment, and more specifically, to a nasal mask for an air filter. Background technique [0002] Looking at the development of global modernization, due to construction, road construction, mines, factories and automobile exhaust pollution, dust and haze pollution is everywhere, which restricts people's access to work and life, so people usually wear masks when they go out. Most masks are generally worn tightly around the mouth and nose, which causes a lot of inconvenience to the users, and the effect of ordinary civilian masks is not up to the requirements. The exhalation and inhalation are all inside the mask, and wearing it for a long time will easily cause secondary pollution, and wearing it on the Wearing the ear for a long time will easily cause pain in the root of the ear, and it is not easy to dissipate heat; although the labor protection mask is good, it is not beautiful, and it is n...

Problems solved by technology

In order to pass dirty air through and purify it, these filters are used as filter materials, and the structure of the fittings that install the filters into the nostrils allows them to be installed at the entrance of the nostrils or on the bridge of the nose. Therefore, in the past As for the nasal mask, its disadvantages are that the nostrils cause the nose to bulge because the filter is inserted, and at the same time, the beauty of the nose is damaged because the installation part of the filter for covering the nostrils is installed to cover the bridge of the nose, etc., and Since the mask part is close to the position outside the nostrils, it is easy to fall off, and the filter material used cannot effectively isolate harmful micro-pollutants in the air
