Embodiment Construction

[0014] The positive pressure breathing dustproof device comprises a protective cap 2 with a mask 1, a dust filter 3, an induced draft fan 4, an air pipe 5, a head frame 6 and a mask 7. The dust filter 3 and the induced draft fan 4 are installed in the same outer casing 8 , and the outer casing 8 has an air inlet 9 and an air outlet 10 . The induced draft fan 4 is powered by a nickel metal hydride battery 11 . Ni-MH battery can supply power for 8 hours continuously. The periphery of the lower end of the protective cap 2 is fixedly connected with the inner wall of the head frame 6, and the outer shell 8 equipped with the dust filter 3 and the induced draft fan 4 is fixed on the head frame 6. One end of 5 is connected with the air outlet 10 on the outer shell 8, and the other end is fixed on the inner wall of the front part of the protective cap 2. The outer edge of the mask 1 is fixed with abrasive plastic stickers, and the inner edge of the mask 1 is an elastic band structure ...

Abstract

A positive type dust proof device for respiration is provided. It comprises a protection cap with a mask and a facial glass. The key points lie in that: a head frame is provided on the upper end of the protection cap, the periphery of the lower end of which is closely connected with the inner wall of the head frame. An outer case installed with a dust filter and an induced draft fan is fixed to the head frame. An air delivery tube is installed along the inner wall of the protection cap. One end of the air delivery pipe is connected with the air outlet of the outer case, while the other end of which is fixed on the inner wall of the protection cap front part, the outer edge of the facial mask is closely connected with an abrasive plastic plaster to joint with the facial glass the inner edge periphery of the facial mask is of an elastic band structure. the induced draft fan get electricity from a DC supply. It can ensure the personnel working in the dust and harmful gas filled environment away from the silicosis caused by the dust absorption and harmful gas.

Description

(1) Technical field [0001] The invention relates to an occupational disease protective device, in particular to a head-mounted dust-proof device for preventing silicosis. (2) Background technology [0002] In the course of nearly 20 years of reform and opening up, China's economic development has made remarkable achievements. While the economy has taken off, the quality of life of the Chinese people is undergoing qualitative changes. and healthy. Work is not only an important basis for providing basic security for people's lives, but the quality of working conditions also affects everyone's health and safety. However, over the past 50 years since the founding of the People's Republic of my country, the record of occupational diseases in our country has remained high. In the process of our efforts to become a world economic power, we have still maintained the record of being the world's leading silicosis country. Due to the various health-hazardous pollutants in the workpla...
