Abstract

The invention relates to the field of personal respiratory protective full-face masks, and discloses a full-face mask provided with a mouth-nose mask support plate, which can be applied to a gas mask full-face mask, a self-supporting open-circuit compressed air full-face mask, and a positive-pressure fire-fighting air respirator full-face mask , full-face masks for oxygen respirators, full-face masks for medium-pressure respirators, etc. It solves the problem that the existing full-face masks on the market have no mouth-nose mask support plate. Due to the lack of support, the extrusion force between the upper end of the nose of the mouth-nose mask and the upper end of the nose of the user is not enough, and the problem of easy deformation and air leakage is solved. The invention provides a support plate for the mouth and nose mask in the full face mask. The support plate is preferably made of rigid plastic material. , Increase the support force of the nose position, so that the mouth and nose mask fits closely with the user's face without air leakage.

Description

technical field [0001] The invention relates to the field of personal respiratory protective full face masks, in particular to a full face mask provided with a mouth and nose mask support plate, which can be applied to gas mask full face masks, self-contained open-circuit compressed air full face masks, positive pressure fire fighting air respirator full face masks , full-face masks for oxygen respirators and full-face masks for medium-pressure respirators, etc. Background technique [0002] Existing full-face masks on the market do not have an oronasal mask support plate. Due to the lack of supporting force, the extrusion force between the upper end of the nose of the oronasal mask and the upper end of the user's nose is not enough, and it is easy to deform and cause air leakage. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a full-face mask provided with an oronasal mask supp...
