Abstract
A protecting (or welding) face shield without generation of fog features that it has an internal mouth-nose mask and the air outlets in the front of mouth-nose mask and under it for exhausting the CO2 expirated by the mask.
Description
Technical field
The invention belongs to the protective mast class, relate to a kind of protective mast and welding mask of difficult generation fog.
Background technology
Existing protective mast and welding mask all do not have oronasal mask, so, the carbon dioxide that human body is breathed out very easily produces fog on the transparent face mask sheet before sight line or the screening glass, influence vision even covers sight line, and make gas concentration lwevel in the face shield increase that influence is breathed and health.
Summary of the invention
At above problem, the purpose of this invention is to provide on a kind of transparent face mask sheet the welding mask that is difficult for producing fog on the protective mast that is difficult for producing fog and a kind of screening glass.
A kind of protective mast of difficult generation fog comprises transparent face mask, it is characterized in that: establish on transparent face mask inboard and the corresponding position of mouth and nose oronasal mask is housed, and be provided with QI KOU in the bottom and the positive front portion of oronasal mask, just forward QI KOU is led to outside the transparent face mask.
A kind of welding mask of difficult generation fog comprises face shield and protective eye lens, it is characterized in that: establish on face shield inboard and the corresponding position of mouth and nose oronasal mask is housed, and be provided with QI KOU in the bottom and the positive front portion of oronasal mask, just forward QI KOU is led to OFP.
The objective of the invention is by face shield inboard with the corresponding position of mouth and nose on establish the dress oronasal mask, and be provided with QI KOU in the bottom and the positive front portion of oronasal mask, just forward QI KOU leads to that OFP realizes.So, the carbon dioxide of exhalation can only be from the bottom of oronasal mask or just forward OFP discharge, make the transparent face mask sheet of top or screening glass be difficult for producing fog, can not influence sight line; Also has energy filtration, purification air, allow human body suck the air of pure and fresh health, guarantee physical and mental health, fully guarantee work quality and efficient, particularly can establish and adorn different filter cartridges or filtrate the air of working environment is filtered, become dustproof, gas defence protective mast and welding mask with dustproof, gas defence function according to the air of working environment.
Description of drawings
Fig. 1 is a kind of protective mast structural representation of the present invention,
Fig. 2 is a kind of welding mask structural representation of the present invention.
Among the figure: (1) filter outer housing, (2) face shield QI KOU, (3) face shield, (4) head-shield, (5) filter box, (6) airway, (7) one-way gas flow valve, (8) positive anterior QI KOU, (9) head hoop, (10) bottom QI KOU, (11) oronasal mask, (12) filtering air inlet, (13) protective eye lens.
The specific embodiment
Describe in detail below in conjunction with embodiment and accompanying drawing thereof:
Among the figure, the QI KOU (8) that the positive front portion of oronasal mask (11) is provided with is to connect by the face shield QI KOU (2) that is provided with face shield (3) that to lead to face shield (3) outer.
In order to ensure the physical and mental health of user, fully guarantee work quality and efficient, and protective mast and welding mask can be used under specific environment, can establish dress air filter (1) at the front end of the air inlet of the oronasal mask (11) of protective mast and welding mask.Protective mast among the figure and welding mask can be established in the cavity between filter outer housing (1) or filter box (5) and face shield (3) according to the air of working environment and adorn different mediums and just can the air of working environment be filtered, and make it become dustproof, gas defence protective mast and the welding mask with dust proof and gas defence function.
For the ease of filter is installed, preferably the just forward QI KOU of oronasal mask (11) (8) is made as air inlet, the QI KOU of bottom (10) is made as the gas outlet.Can only give vent to anger for the gas outlet that makes oronasal mask (11) can not air inlet, air inlet can only can not be given vent to anger in air inlet, guarantee the health with fresh air in the oronasal mask (11), be equipped with one-way gas flow valve (7) on the gas outlet (10) of the oronasal mask among the figure (11) and the air inlet (8).
For making oronasal mask (11) can be close to different people on the face, protective mast among the figure and the oronasal mask of welding mask (11) are hinged on face shield (3) or the filter box (5); Airway (6) is a flexible pipe, i.e. the pipe that flexible can curve again; And on face shield (3) or oronasal mask (11), be provided with and make oronasal mask (11) be close on the face securing member.
