Abstract

A dustproof and antigas safety helmet comprises a safety helmet body, a respirator and an eye patch, wherein the eye patch is connected with the lower edge of the safety helmet body through elastic bands, and the respirator is matched with the nose and the mouth of a user; the safety helmet body sequentially comprises an outer helmet shell, a first filtering layer, a first gas channel and an inner helmet from outside to inside, air inlets with valves are formed in the two ends of the outer helmet shell, the first filtering layer is of a hollow structure, provided with a filtering material and communicated with the first gas channel, gas outlets with valves are formed in the two ends of the first gas channel and provided with gas pipes communicated with the respirator, and a one-way air outlet valve is arranged on the respirator. The dustproof and antigas safety helmet can be adaptive to many different occasions, the load of the user can be relieved, the filtering face is large, the filtering effect is good, and the dust retardation rate is large; it is effectively avoided that carbon dioxide which the user breathes out in the breath process is breathed in again, and the uncomfortable feeling of the user is greatly relieved.

Description

technical field [0001] The invention relates to the field of protective devices, in particular to a dustproof and poisonous safety helmet. Background technique [0002] It is inconvenient to wear all kinds of dust masks on the market, and it is easy to inhale the second time of carbon dioxide exhaled during breathing, which makes the body uncomfortable due to the amount of oxygen absorbed by the human body. The filter surface of commercially available dust masks is small, the filter effect is not ideal, and the dust-resistance rate is low. In some working areas with high concentration of smoke, the masks are easy to lose the dust-proof effect. [0003] At the same time, the outer layer of the traditional dust mask often accumulates dirt such as dust and bacteria in a lot of outside air, while the inner layer blocks exhaled bacteria and saliva, so it also has some adverse effects on the user. Moreover, When wearing it, as the working time changes, the breathing resistance be...
