Firefighting self-rescue respirator

Abstract

The invention belongs to the technical field of firefighting equipment, and particularly provides a firefighting self-rescue respirator. The self-rescue respirator comprises a fireproof helmet and a filtering tank; an eye window is arranged on the outer wall of the fireproof helmet; a transparent thin film is adhered to the outer surface of the eye window; a supporting plate is installed on the fireproof helmet on one side of the eye window; slide rods are symmetrically connected with the lower end and the upper end of the supporting plate; slide blocks are slidably connected with the slide rods; springs are sleeved on the slide rods between the slide block and the supporting plate; first magic tape is arranged on the side surfaces of the slide blocks; second magic tape is connected with the end parts of the transparent thin film. Through the arrangement of the transparent thin film and a sliding mechanism, a user wearing the respirator can remove the transparent thin film with dust thereon from the eye window via the sliding mechanism, the visual clearness of the user is greatly improved, and at the same time the transparent thin film is conveniently and rapidly removed, so the effectiveness and rapidness of use of the firefighting self-rescue respirator can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a fire-fighting self-rescue respirator. Background technique [0002] Fire self-rescue respirator, also known as air respirator, fire-fighting air respirator, is a self-contained open air respirator, widely used in fire protection, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories, mines and other departments for firefighters Or emergency rescue personnel can safely and effectively carry out fire extinguishing, emergency rescue and rescue work in various environments such as dense smoke, poisonous gas, steam or hypoxia. And existing fire-fighting self-rescue respirator has the following problems: because firefighters or emergency rescuers need to wear fire-fighting self-rescue respirator for a long time when extinguishing a fire, especially after the eye window is glued with water, a large amount of air can be accumulated on the eye wi...

Problems solved by technology

And existing fire-fighting self-rescue respirator has the following problems: because firefighters or emergency rescuers need to wear fire-fighting self-rescue respirator for a long time when extinguishing a fire, especially after the eye window is glued with water, a large amount of air can be accumulated on the eye window The dust and ashes floating in the air when the fire burns will obscure the sight of firefighters or emergency rescue personnel, affecting fire fighting and disaster relief work

[0004] And although the respirator in the above-mentioned scheme can remove the dust and impurities on the eye window by setting water spray and scraping mechanism, the respirator loaded with a certain amount of water makes its own weight increase, which virtually increases the user's workload. Moreover, the amount of water in the respirator is limited, and the effect of continuously cleaning the eye window cannot be achieved. At the same time, the water flow and the wiper blade will also affect the wearer's field of vision when in use, and the cleaning effect on the surface of the eye window is not good, thereby reducing The effect of respirator use
