Embodiment Construction

[0020] figure 1 A specific embodiment of the fresh wind face mask of the present invention is shown. The mask shell 1 is provided with an air nozzle 2, the air nozzle 2 is connected with the air guide tube 4, the air guide tube 4 is equipped with an air regulating valve 5, and then communicated with the air supply system, and the mask shell 1 is provided with a sealing soft edge 3. The lower edge is provided with an air outlet 6.

[0021] Of course, the air nozzle 2 can also be designed as a plurality of air jets arranged around the mask shell 1; the air outlet 6 can also be designed as a plurality of external small openings.

[0022] In actual use, the fresh air mask should be used in conjunction with the air supply system. The air supply system is very simple, as long as fresh air with a certain pressure can be connected to the air duct 4. One air supply system can be used by several fresh air masks at the same time.

[0023] After people put on the mask, the air supply ...

Abstract

The invention discloses a pure air mask which comprises a mask shell, an air nozzle, a sealing soft edge, an air guide pipe, an air adjusting valve and an air flow discharge port. The mask shell is provided with the air nozzle which is connected with the air guide pipe, the air adjusting valve is mounted on the air guide pipe to be communicated with an air supply system, the sealing soft edge is arranged around the mask shell, and the air flow discharge port is arranged at the lower edge of the sealing soft edge. By adopting the working mode that the air nozzle constantly supplies air into the mask shell and air pressure in the mask shell is continuously discharged from the air flow discharge port, inhalation of pure air is guaranteed while comfortableness and economy in use are taken into consideration.

Description

technical field [0001] The invention relates to a gas repellent mask, in particular to a fresh air mask which utilizes an atmospheric wind source to continuously maintain flowing fresh air with a slight pressure in the mouth and nose cavities, so that the mouth and nose can breathe freely and the outside air cannot invade. Background technique [0002] According to reports from authoritative organizations: At present, there are at least 6 million domestic cumulative cases of pneumoconiosis and suspected pneumoconiosis (0+) cases in China. I also believe that this number is not too small, because my "pressure-guiding bedpan" patent was implemented in Guangdong Chaozhou Hengjie Sanitary Ware Factory. After four years of personal experience, I was even worried that I might "won the bid" unconsciously. [0003] Pneumoconiosis is the most serious occupational disease that endangers the health of workers in our country. Especially in the coal and ceramic industry systems, pneumoc...
