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, and the structure diagram of the mask shell 1 is not lim...

Abstract

The invention discloses a fresh air supplying face mask which comprises a face mask housing, an air nozzle, a sealing soft edge, an air guiding pipe, an air adjusting valve and an airflow discharge port, wherein air is unceasingly supplied into the face mask housing through the air nozzle; the smooth airflow discharge port is formed in the lower edge of the face mask housing; and the intensity of the pressure in the face mask housing is controlled by the air adjusting valve. According to the invention, the working mode that the air is unceasingly supplied into the face mask housing through the air nozzle and the pressure in the face mask housing is continuously discharged from the airflow discharge port is adopted, so that not only is inhalation of pure air ensured, but also the comfort and economy are taken into consideration, and therefore, the face mask is an ideal solution for dust erosion and poison gas damage.

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 Chaozhou Sanitary Ware Factory in Guangdong. After four years of personal experience, I was even worried that I might "won the bid" without knowing it. [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...
