The air supplying type dust mask enabling the user to breathe smoothly comprises a mask and an air suction pipe, wherein one end of the air suction pipe is connected with the mask, and the other end of the air suction pipe is connected with an air pipe or an air blower. The air supplying type dust mask enabling the user to breathe smoothly is characterized in that more than two air holes are formed in the front face or the side face of the mask or in the front face and the side face of the mask, a filter screen attached to the inner wall is arranged on the inner side wall of the mask, and breathable cloth used for protecting a face portion is arranged on the reverse side of the mask. According to the air supplying type dust mask enabling the user to breathe smoothly, the plurality of air holes are added to the mask and are beneficial for smooth breath, the breathable cloth is added to the reverse side of the mask to protect the face portion from being directly impacted by air flow better, and harm on the face portion from the air flow is greatly reduced.
Description
Technical field
The utility model belongs to the dust mask technical field, and what be specifically related to the smooth and easy breathing of a kind of energy gives gas formula dust mask.
Background technology
At present, the workman who works under dust or air quality rugged environment such as the carpenter, be subject to the pollution of wood powder.Building stones cutting worker will be subject to the pollution of building stones dust.The Spray Painter will be subject to the pollution of paint spray.The workman of above-mentioned industry needs to wear dustproof when operation or filters the face shield of usefulness, people have proposed the technical scheme of multiple dust mask for this reason, such as the patent No. be: ZL 200720100725.3, notification number: " to the gas formula dust mask " that CN 201026352Y proposes; The patent No. is: 200620140881.8, notification number: " the suction-chamber's outer air dust-proof anti-gas mask " that CN 200977341Y proposes, although above-mentioned technical scheme has solved the workman's who works dustproof problem to a certain extent under dust or air quality rugged environment, but above technical scheme all is to input air in the face shield by an air feeder, in input air, because the limited space in the face shield and the steam vent of face shield is too small or very little, gas can form fixed air pressure in face shield, cause constriction for the masked workman's that wears face, breathing is become to have some setbacks, simultaneously face is also caused great injury, therefore in the application of reality, be difficult to popularize.
Summary of the invention
The purpose of this utility model be to provide the smooth and easy breathing of a kind of energy to gas formula dust mask; a plurality of steam vents have been increased on its face shield; the inboard of face shield has increased screen pack; increased breathable cloth for the protection of face at the reverse side of face shield; so that breathing, the workman becomes smooth and easy when using face shield; facial also not in the impact that directly is subjected to air-flow, thus face protected greatly.
Above-mentioned goal of the invention is achieved through the following technical solutions; the smooth and easy breathing of a kind of energy give gas formula dust mask; it comprises face shield; one end is connected the air intake duct that the other end connects with ventilation duct or air blast with face shield; its main points are: in the front of face shield or side or positive and side be provided with passage more than 2; be provided with the screen pack of fitting with madial wall at the madial wall of face shield, be provided with breathable cloth for the protection of face at the reverse side of face shield.
The above-mentioned smooth and easy breathing of a kind of energy give gas formula dust mask, one of its structure is described passage and air intake duct and face shield connection place 1-1.5 centimetre apart.
The above-mentioned smooth and easy breathing of a kind of energy give gas formula dust mask, it is grid-like that one of its structure is that passage becomes.
The beneficial effects of the utility model are: increased smooth and easy that a plurality of passages are conducive to breathe more at face shield; reverse side at face shield has been set up breathable cloth; better protect face not to be subjected to the direct impact of air-flow, reduced greatly the injury of air-flow to face.
