Face mask with rotary button on jack of gas supply valve and using method

Abstract

The invention relates to the technical field of air breathing face masks, in particular to a face mask with a rotary button on a jack of a gas supply valve and a using method. A blocking spring is arranged on rotation track of a far end of the rotary button; a limiting groove is formed in one side of the outer wall, opposite to the jack, of a mounting part; two open slots are symmetrically formedin the jack; the two ends of the blocking spring are separately equipped with extending sections; and the extending sections extend to the inner side of the jack through the open slots, and extend tothe outer side of the jack from the inner side of the jack at the tail ends of the open slots. Compared with the prior art, the face mask is simple and feasible in combined structure, is easily mounted and dismounted, and has the advantages that: the defect that operation for an up-down moving type button is inconvenient, and wastes time and labor in the prior art is solved, the gas supply valve can be conveniently and quickly inserted and pulled on the face mask in a labor-saving time-saving mode, inserting and pulling of the gas supply valve can be realized through single-hand operation, theproblem that inserting and pulling of the gas supply valve are inconvenient, and waste time and labor is solved, and the risk caused by inconvenient inserting and pulling of the gas supply valve is avoided.

Description

technical field [0001] The invention relates to the technical field of air breathing masks, in particular to a mask with a rotary button on an air supply valve socket and a use method thereof. Background technique [0002] Respiratory masks with air supply system are widely used in various fields such as escape, rescue, military and so on. Existing air breathing mask is made up of face mask, air supply valve, gas cylinder, decompression system, headband net. When in use, the headband net is fixed on the mask, and the air supply valve inputs the high-pressure air in the cylinder to the mask for the user through the decompression system, so the connection between the air supply valve and the mask is very important. And the existing connection method is to install a button that can move up and down on the air supply valve socket of the mask to drive the switch of the jumper to clamp the air supply valve. This movable button is very inconvenient and laborious when operating, es...

Problems solved by technology

And the existing connection method is to install a button that can move up and down on the air supply valve socket of the mask to drive the switch of the jumper to clamp the air supply valve. This movable button is very inconvenient and laborious when operating, especially in It is very inconvenient when quickly plugging and unplugging the air supply valve on the worn mask, which is very inconvenient
