Description

Gas mask that security performance is high

Technical Field

The utility model relates to a gas mask technical field especially relates to a gas mask that security performance is high.

Background

In some chemical industry factory building workshops, the occasion of people's work can be full of the poison gas usually, inhales for a long time and can produce serious harm to the human body, and the gas mask has been worn to people from this, and the canister that traditional gas mask set up is all taken a breath through the bottom, and the area of taking a breath is little, and gaseous inhalation is too fast when breathing the scratchy, can lead to gaseous effectively not filtered directly to inhale in the human body, causes the result of human poisoning.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing the gas mask with high safety performance.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a gas mask that security performance is high, includes and leaks hopper-shaped gauze mask, leak hopper-shaped gauze mask both sides edge and all bond "Y" shape elastic fixation area, and leak hopper-shaped gauze mask most advanced top and open and have first ventilative mouthful, and the spiro union has the breather pipe in the first ventilative mouthful, the terminal welding of breather pipe bottom has the canister, and the breather pipe has the second bleeder vent with canister's the outer wall of the welding department canister of canister opens, the welding of second bleeder vent inner wall has vertical downward and canister bottom inner wall welded netted breathing pipe, and the equidistant welding of canister lateral wall has the three-layer to keep apart the otter board between netted breathing pipe.

Preferably, the tail ends of the two Y-shaped elastic fixing belts are connected through a plug-in buckle.

Preferably, the side wall of the canister is provided with air holes distributed at equal intervals.

Preferably, a first sponge layer is filled between the canister and the isolation screen plate on the outer side, coal columnar activated carbon is filled between the isolation screen plate on the outer side and the isolation screen plate in the middle layer, and a second sponge layer is filled between the isolation screen plate on the inner side and the reticular air suction pipe.

Preferably, an air chamber is arranged between the middle isolation mesh plate and the inner isolation mesh plate.

Preferably, a layer of silica gel film is bonded on the edge of the funnel-shaped mask.

Preferably, the outer wall of one side of the funnel-shaped mask is sleeved with a piston through an opening.

The utility model has the advantages that:

1. the canister starts to ventilate through the side wall, the area of the side wall of the canister is larger than that of the bottom, the ventilation efficiency is increased, gas entering and exiting is enabled to be smoother, and the canister effect is improved.

2. Through the air chamber, the people can the air chamber can produce the effect of a buffering when the hurried breath, the gaseous abundant filtration toxicity in all can coal column active carbon of messenger's breathing, can filter the dust in the air through first sponge layer, thereby the dust can not cover coal column active carbon and influence the efficiency of straining the poison, can inhale the human body with the granule separation that coal column active carbon surface drops outside the netted suction pipe through second floor sponge layer.
