Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a multifunctional air breathing apparatus. Background Art

[0002] Air respirator is also called gas storage gas mask, sometimes also called fire mask. It uses compressed gas cylinder as gas source, but the gas contained in the cylinder is compressed air. It is widely used in fire protection, chemical industry, shipping, petroleum, smelting, warehouse, laboratory, mine and other departments. It allows firefighters or emergency rescue personnel to safely and effectively carry out fire extinguishing, disaster rescue and rescue work in various environments such as thick smoke, poisonous gas, steam or lack of oxygen.

[0003] However, the air respirators currently on the market have a complex structure and a single function. They are unable to filter and humidify the air output from the cylinder. When firefighters enter a fire scene, the high ambient temperature and the dry air they breathe in can easily cause discomfort to the firefighters, thus affecting the efficiency of firefighting work.

When firefighters enter the fire scene, due to the high ambient temperature and then exhale dry air, they are likely to feel uncomfortable, thereby affecting the efficiency of firefighting work.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

[0006] A multifunctional air respirator comprises a cloth bag, a gas cylinder is arranged in the cloth bag, a regulating valve is arranged on the top of the gas cylinder, a pocket is arranged on the cloth bag, a humidifying and filtering mechanism is arranged in the pocket, the humidifying and filtering mechanism comprises a shell arranged in the pocket, a top cover is threadedly connected to the top of the shell, two symmetrically arranged supporting layers are arranged in the shell, a humidifying filler layer is arranged between the two supporting layers, a filtering filler layer is arranged above the humidifying filler layer, a water pipe is connected to the outer side surface of the shell, a water bag is arranged at the end of the water pipe away from the shell, a first connecting pipe is arranged between the top cover and the regulating valve, a second connecting pipe is connected to the bottom of the shell, and a mask is arranged at the end of the second connecting pipe away from the shell.

[0007] Furthermore, the water pipe is communicated with the humidification filler layer.

[0008] Furthermore, a medical sponge is arranged in the humidifying filler layer.

[0009] Furthermore, medical activated carbon is provided in the filter filler layer.

[0010] Furthermore, the second connecting pipe is connected to a pressure gauge via a three-way quick-connect connector.

[0011] Furthermore, both the first connecting pipe and the water pipe are provided with a one-way valve.

[0012] Furthermore, the cloth bag is provided with two symmetrically arranged shoulder straps.

[0013] The beneficial effects of the utility model are:

[0014] The utility model discloses a multifunctional air respirator, which filters the gas outputted from the gas cylinder through the humidifying and filtering mechanism, and the filtering filler layer humidifies the gas. When the firefighters feel the air is dry, they squeeze the water bag to replenish water to the humidifying filler layer, thereby preventing the firefighters from inhaling too much dry air in a high temperature environment when fighting a fire and causing discomfort, thereby ensuring the working efficiency of the firefighters.

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0020] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0022] like Figure 1 to Figure 2As shown, a multifunctional air breathing apparatus comprises a cloth bag 1, a gas cylinder 2 is arranged inside the cloth bag 1, and two symmetrically arranged shoulder straps 17 are arranged on the cloth bag 1 to facilitate firefighters to carry the gas cylinder 2.
