Problems solved by technology

After repeated practice, it was found that the performance of the "breeze mask" has certain limitations: the air flow is too large, and the face cannot bear it; the air flow is small, and the external air flows back when inhaling; feeling a little suffocated

Embodiment Construction

[0023] figure 1 A specific embodiment of the long-tube fresh air 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. There is an air outlet 6 on its lower edge, and a tail pipe 7 with sufficient volume is connected behind the air outlet 6. The standard is: the air ejected from the spray nozzle and the tail pipe when people inhale vigorously. The sum of the air in the volume is greater than the amount of air needed when people inhale vigorously, and the most end of the tail pipe 7 is the terminal outer discharge port 8 .

[0024] When designing, the air nozzle 2 can also be designed to be arranged around the mask shell 1 as a plurality of air nozzles; the air outlet 6 can also be designed as a plurality o...

Abstract

The invention discloses a long tube and fresh air mask which comprises a mask housing, an air nozzle, a soft sealing edge, an air guide tube, an air adjustment valve, an airflow discharge port, a tail discharge duct and a terminal discharge port. A working mode that the air nozzle continuously supplies air to the mask housing and air pressure in the mask housing is continuously discharged from the airflow discharge port is adopted, and sufficient air flow during inspiration is kept by utilizing the volume of the tail discharge duct, so that the use comfortability and the economy are ensured while the fresh and pure air is inspired, and the mask is really an idea scheme for solving dust erosion and toxic gas harm problems.

Description

technical field [0001] The invention relates to a gas mask, in particular to a gas mask that utilizes an atmospheric wind source to continuously maintain the flowing fresh air with a slight pressure in the mouth and nose cavity, and unimpeded airflow. A long-tube wind mask that breathes freely and prevents outside air from entering. 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 syste...
