Its design features usually include a nuclear full-face mask system, an ultra-wide field of view mask, and a self-priming filtration system. The anti-tritium mask can effectively filter out particles and aerosols contaminated with radionuclides in the environment through its special filtration system, thereby reducing the internal irradiation caused by the penetration of the respiratory system. The filter system of this mask is replaced according to the usage.

[0003] The current tritium protection equipment includes gas suits and filter paper respirators. The gas suit equipment is relatively large, and there are pipes connecting the gas suit and the equipment, which restricts the movement of workers and makes their activities inconvenient. The humidity of the air filtered by the filter paper respirator is too low, which can easily cause intolerance to personnel. At the same time, the filter element material is relatively dense, so breathing is more laborious after wearing it, and the comfort level is low.

[0004] In view of this, the utility model provides an auxiliary air supply tritium protection mask. Utility Model Content

The vibration plate 403 works to atomize the moisture in the humidification cotton swab 406 to achieve the effect of humidifying the air inside the breathing mask 1. After optimizing the air humidity, the single-wearing tolerance of the staff can be effectively increased, and the comfort and duration of work can be increased.

[0032] According to the above disclosure of the specific structure of the motor filter box assembly 6, the motor filter box assembly 6 includes a shell 601 for protection and a filter element 602 for air filtering, the outer surface of the shell 601 is provided with a filter element interface 603 for installing the filter element 602, and a rubber gasket 604 for tight installation is installed inside the filter element interface 603, and a filter box cover 605 for convenient opening and closing of the shell 601 is installed on the top of the shell 601, and an air pipe interface 606 for docking and installing the air pipe 5 is opened on the top of the filter box cover 605, and a filter box tube 607 docked to the inside of the filter element 602 is installed at the bottom of the air pipe interface 606.

After use, pull out and replace with a new filter element 602. The filter element 602 is connected to the filter box tube 607 through the filter element interface 603. The rubber gasket 604 is used to seal to prevent leakage from the interface. The small motor 8 transmits the filtered gas in the filter box tube 607. The top of the filter box tube 607 is connected to the bottom of the trachea interface 606 for connection with the trachea 5. The filter box cover 605 is opened when replacing the internal rechargeable battery 9. The rechargeable battery 9 is used to supply power to the small motor 8. The wind speed supplied by the small motor 8 is 5-10L / min, which is divided into three gears for adjustment. The elastic belt 11 is connected to the rubber hanging ring 10 and can be hung on the waist of the human body. The device is small in size and easy to carry.
