Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to a breathing mask connecting structure. Background Art

[0002] A breathing mask is a device used to protect the respiratory system, usually fixed to the head by an adjustable strap, covering the mouth, nose and chin. It can filter particulate matter and harmful substances in the air and prevent the inhalation of harmful gases, dust, smoke, bacteria and viruses, etc.

[0003] When using a breathing mask, the breathing mask will be fixed with a strap. By adjusting the length of the strap, the mask can be fixed on the face, and then the filter box is installed. The air is filtered through the filter box to allow clean gas to enter the inside of the mask, thereby achieving the purpose of filtration. However, the replacement time of the filter element is uncertain. Generally, it is judged whether it needs to be replaced when the breathing resistance becomes larger or an odor is smelled when inhaling. When replacing, the filter box needs to be disassembled, and then the filter box is opened to replace the filter element, which takes a certain amount of time. When the breathing mask needs to be replaced when used, it is easy to inhale toxic gases, viruses, etc., thereby endangering physical safety. Utility Model Content
