Description
Technical field
The utility model relates to a kind of dust mask, relates to a kind of pressure-fired lightweight dust mask specifically, and it can make the air in the face shield be slight positive pressure state, and the air quality in guaranteeing to cover is not subjected to dust pollution.
Background technology
Stone pit and each workshop in the cement plant, airborne dust pollution is very serious, much work positions are in outdoor, half outdoor or open-air place, can't use air cleaner at all, the workman who works under such environment masks one's nose and mouth with a cloth or easy anti-dust nose mask, and their eye exposure is in dust.Work masks one's nose and mouth with a cloth under such environment, the as easy as rolling off a log respiratory tract that sucks from the nose both sides of dust, though and it is relatively good to have on the dustproof effect of easy anti-dust nose mask, but breathe relatively effort, time has been grown and also can allow the people be difficult to stand, particularly workman's eye exposure in dust, friction and the chemical action of dust granules in workman's eyes, make that a lot of people's eyes are aglow, shedding tears frequently.Domestic someone once attempts to use the dust mask of helmet form, but because helmet heaviness is very inconvenient while working after putting on, so can't promote.
The utility model content
The purpose of this utility model is exactly in order to remedy the deficiencies in the prior art, a kind of pressure-fired lightweight dust mask is provided, it can overcome the shortcoming that Dust proof helmet is heavy and breathing is required great effort in the prior art effectively, it relies on the little blower fan of carrying to build a pressure-fired environment in face shield in the local little space, so both can make breathing smooth and easy, and can not be subjected to the dust infringement again.When little blower fan can't be worked, the utility model still can be used as common dust mask to be continued to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pressure-fired lightweight dust mask, comprise face shield, dust cover, form, appendix, fixed band, blower fan, dust cover, battery, hook, wherein face shield is made by rubber or nonwoven, overall profile is roughly as people's face, after being worn over it on the face, it and people's face contour is very identical, seal degree is better, place, nostril at face shield is fitted with a dust cover, bridge of the nose place at face shield inserts an appendix that is used to import clean air, a pair of glass vision panel is equipped with at eyes place at face shield, a fixed band that is used for fixing face shield is equipped with at the ear place of corresponding human body in the face shield left and right sides, the air outlet that is connecting a blower fan at the other end of appendix, the air inlet place of blower fan is adorning a dust cover, and the bottom of blower fan is connecting a battery, has one to be used for blower fan is hung over hook on the waistband on the left side of blower fan.
Using method of the present utility model is: open blower fan after putting on this face shield, the clean air after dust cover filters makes to be pressure-fired in the face shield in appendix enters face shield, and at this moment dust can't enter face shield under the acting in conjunction of this malleation and dust cover.When exhausting, the battery electric energy also can utilize the dust cover of nose to prevent dust.
The beneficial effects of the utility model are: simple in structure, put on its back action conveniently, and it is unaffected to work, good dustproof effect.
