Problems solved by technology

[0003] The structure of the positive pressure air respirator is relatively complicated, and the air source is an air tank filled with high-pressure air. During the fire fighting process, the high-pressure air tank carried on the back is prone to explosion accidents when the external temperature is relatively high, and it has a certain degree of safety. hidden dangers; secondly, the small size of the gas tank often cannot meet the search and rescue needs of firefighters; thirdly, with the progress of breathing, the air pressure of the gas tank gradually decreases, which cannot achieve air flow and cause failure

Embodiment 1

[0019] Such as figure 1 As shown, a wearable air respirator includes an air source and a mask 3 connected to each other, the air source is a wearable airbag 1, and several airbags are provided on the wearable airbag 1 for connecting the inflator and the mask 3 The air hole 1-1 of the wearable airbag 1 is provided with at least one set of first straps 1-2 for fixing; the mask 3 is provided with at least one set of second straps 3-2 for fixing. 2, the mask 3 is provided with an air intake pipe 3-3 for supplying air to the human body and an air outlet pipe 3-4 for exhausting, the air intake pipe 3-3 and the air outlet pipe 3-4 are all matched with the air hole 1-1, And the inlet or outlet of any pipeline of the air inlet pipe 3-3 and the air outlet pipe 3-4 is provided with a small fan for circulating the air flow.

[0020] In this embodiment, the shape of the wearable airbag 1 is a common clothes shape, and the traditional way of using the air tank as the air source of the air ...

Embodiment 2

[0024] Further improvement on the basis of Embodiment 1, in order to allow the mask 3 to fit various human faces, a soft rubber matching face frame 3-1 is provided at the edge of the mask 3 .

Embodiment 3

[0026] Further improvement on the basis of Embodiment 1, in order to prevent the water mist formed on the face shield 3 from the water vapor generated by breathing from affecting the line of sight, the face shield 3 is provided with a sight glass 4 that fits the eyes, and the edge of the sight mirror 4 Be provided with the flexible glue that isolating water vapor matches picture frame 4-1.

Abstract

The invention discloses a wearable air respirator and belongs to the field of firefighting equipment. The respirator comprises an air source and a mask which are connected with each other, the air source is a wearable air bag, and the wearable air bag is provided with multiple air holes for connecting an aerator and the mask, and one or more sets of first bandages for fixing are arranged on a lappet of the wearable air bag; one or more sets of second bandages for fixing are arranged on the mask, an air inlet pipe for supplying air to the human body and an air outlet pipe for air discharge arearranged on the mask, the air inlet pipe and the air inlet pipe are matched with the air holes, and a small-sized fan for airflow circulation at an inlet or an outlet of any one of the air inlet pipeand the air outlet pipe. As the air source, compared with an air tank, the wearable airbag has the advantages of being lower in size, higher in capacity, longer in application time and capable of providing enough time for firefighters for search and rescue.

Description

technical field [0001] The invention belongs to the field of fire fighting equipment, and in particular relates to a wearable air respirator. Background technique [0002] Air breathing apparatus is an important fire-fighting equipment, mainly used in fire-fighting, chemical industry, shipbuilding, petroleum, smelting, factories, mines, laboratories, etc. Safely carry out fire extinguishing, emergency rescue and rescue work in the environment. The air respirator currently used is a positive pressure air respirator, which has the advantages of convenient maintenance, comfortable wearing, and stable performance. It is an ideal personal respiratory protection device for emergency rescue and fire fighting operations. [0003] The structure of the positive pressure air respirator is relatively complicated, and the air source is an air tank filled with high-pressure air. During the fire fighting process, the high-pressure air tank carried on the back is prone to explosion accid...
