Multipurpose mine dustproof device

Abstract

The invention discloses a multipurpose mine dustproof device. According to the device, a pair of protective glasses and a nose mask are fixedly connected into a whole. The protective glasses are connected with the nose mask through fastening belts, length adjusting buckles are arranged on the fastening belts on two sides, and spring bolts and locker are arranged at two ends of the fastening beltsrespectively. A nose clip I for clamping a nose bridge is further arranged on the nose mask, exhaust holes are formed in a lower portion of the nose mask, filtering devices communicating with air inlet holes and one-way valves connected with the exhaust holes are arranged in the nose mask, a water absorption pad is arranged on a lower portion of an inner side of the nose mask, and a nose clip II for controlling the nose clip I is arranged on the lower portion of the nose mask. The dustproof device has the advantages of simple and reasonable structure and diversified and practical functions, the dustproof problem of workers in a high-dust-concentration place is effectively solved, the current industry blank is filled, and the device has good social and economic benefits.

Description

Technical field [0001] The invention relates to the technical field of dust-proof equipment, and relates to a dust-proof device, in particular to a multi-purpose mine dust-proof device. Background technique [0002] Due to the development of human civilization, various air pollution and even bacteria, viruses and other harmful substances have caused more and more harm to people, and the wearing of oronasal masks is the first line of defense to protect human health. However, the currently known oral and nasal masks cannot simultaneously have high air tightness, high comfort and high air permeability. For N95 masks with a higher level of protection, in order to maintain their high air-tight effect on the bridge of the nose and around the face, metal beading and elastic bands must be used to make the face highly oppressed, which can easily cause discomfort and reduce people Willingness to wear. Although common commercially available masks are more comfortable than N95 masks, they ...

AI Technical Summary

Problems solved by technology

The currently commonly used protective glasses have single specifications, poor adaptability, and do not meet the general conditions

In production and life, people in some dangerous projects, such as decoration workers, auto repairers, steel workers, motorcycle drivers, etc., should wear goggles to prevent accidental eye injuries. Glasses are difficult to use and discarded. For example, dust collectors in coal mines, because the eyes are still far away from the glasses, it is easy to cause dust particles from the outside to enter the glasses, affecting their sight. Closed eyes are prone to eye infections

[0004] Many workers working in high-dust places have to wear protective glasses and dust masks at the same time in order to solve the problem of dust prevention. However, although this mask can solve the problem of dust prevention, there are many inconveniences. It is very inconvenient, brings a lot of discomfort to users, and seriously affects work efficiency
