Benefits of technology

This technology makes it easy for workers who work at high levels with fine particles or other harmful substances on their hands without getting sick because they don't get stuck by them when breathing out these things during long hours.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of air purification systems during industrial production without causing negative effects on humans or reducing productivity due to poor indoor environmental hygiene standards. Current solutions involve developing better filters such as clothmasks and other types of plasma generators, while finding ways to provide effective measures against lung disease caused by particulate matter exposure remains challenges because they lack complete enclosure from outside sources like windblown particles.

Embodiment 1

[0020] Positive pressure respirator, including helmet 1 and dustproof device.

[0021] The dustproof device includes a dust filter 2, an induced draft fan 3, an air pipe 4, a protective cover assembly and a power supply 5.

[0022] The protective cover assembly includes a protective cover 6, a clip 7, a mask 8, and two spring-loaded pull rods 9. Face shield 8 is made of rainproof cloth, and air vent is arranged on it, and face shield 8 outer periphery and protective cover 6 outer periphery are pasted by the grinding-plastic paste that is fixed thereon. The inner periphery of the mask 8 is an elastic band 17 . The outer edge of the clip 7 is in matching contact with the inner side wall of the upper frame 10 of the protective cover 6 . There is a groove on the inner edge of the clip 7, and the front part of the brim 11 of the safety helmet 1 is inserted into the groove on the inner edge of the clip. The window 12 of the protective cover 6 is a transparent polycarbonate mirror...

Embodiment 2

[0024] Example two such as figure 2 Shown, this positive pressure type respirator is basically the same in structure with embodiment one, and difference is that protective cover is opaque body except window 12, and window 12 is welding lens or optical control lens. This dustproof device is suitable for electric welding operation.

Embodiment 3

[0026] Embodiment three such as image 3 As shown, the positive pressure respirator is basically the same in structure as the first embodiment, except that a shawl 15 is attached. During use, the staff first puts on the shawl 15, and then puts on the dustproof device.

Abstract

A positive pressure type respiration protector comprising a dust filter, an induced draft fan, an air delivery pipe and protection cover assembly is provided. The protection cover assembly includes a protection cover, a buckle clip and a mask, the mask is plastered to the protection cover by an abrasive plastic paste, and the outer edge of the buckle clip forms an air tightness contact with the upper ledge inner wall of the protection cover, a flute is provides on the inner edge of the buckle clip, being socket with a the front part of the safety cap, the protection cover having a view window is connects with the safety cap by a pin, the dust filter and the induced draft fan are installed inside the casing, the casing is fixed to the safety cap. One end of the air delivery pipe is connected with the air outlet of the case, while the other end of which is connected with the buckle clip air inlet. The invention has simple structure, low cost and favorable dust proof effect. It can ensure the personnel working in the dust filled environment away from the silicosis caused by the dust absorption.
