Abstract
An electric air delivery filtering dust mask is composed of a mask with an exhaust vent, a conducting wire, a filter, a blower fan and a battery, and is characterized in that: the side surface of the mask is provided with the filter and the blower fan, and the filter is composed of a non-woven fabric course, a carbon fiber course, a PP superfine fiber course and a non-woven fabric course, which are positioned in order. The utility model can absorb the air into the filter through the blower fan for filtrating, and then send the clean air into the mask to form the positive pressure, so as to reduce the respiratory resistance, and the dust filtrating precision can reach to 0.3 micro meters, and the antidust rate is equal to or above 99.
Description
Technical field
The utility model relates to the articles for labour protection technical field, particularly a kind of electronic powered air-purifying formula dust mask.
Background technology
The present anti-dust respirator that uses, dust mask multiselect filter paper, or regular carbon granules is done filtering material, its sealing is to realize by mouth mask edge and facial closely cooperating, it is passive filtration, when the people is air-breathing, an external pollution air part enters in the mask after filtering by common filtering material, fine solid particle is then by entering in the mask with the slit that contacts of face, this is because the complete driving fit with face can't be accomplished in the mask edge, so when the people is air-breathing, here become dust and enter the interior passage of mask, because in the face shield is negative pressure structure, it is uncomfortable in chest that the user can feel, calms the anger, scorching and unsmooth breath.
Summary of the invention
The purpose of this utility model provides a kind of dust that can effectively prevent and enters the electronic powered air-purifying formula dust mask in the face shield.
The utility model is to realize like this, it comprises face shield, lead, filter, blower fan and the battery of being with steam vent, it is characterized in that being provided with filter and blower fan in the side of face shield, filter is arranged in order by nonwoven layer, carbon fiber layer, PP superfine fibre layer and nonwoven layer to be formed.
The utility model the air intake filter device and after filtering, is sent into formation malleation in the mask to clean air by blower fan, reduces respiratory resistance, and its Chalk-dust filtering precision reaches 0.3 micron, dust proof rate 〉=99.
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation of electronic powered air-purifying formula dust mask,
Fig. 2 is the structure of filter schematic diagram,
Fig. 3 is the work schematic diagram of electronic powered air-purifying formula dust mask.
The specific embodiment
As Figure 1-3, this electronic powered air-purifying formula dust mask comprises the face shield 2 of being with steam vent 1, lead 3, filter 4, blower fan 5, battery 6, switch 7, nonwoven layer 8, carbon fiber layer 9, PP superfine fibre layer 10 and nonwoven layer 11, be provided with filter 4 and blower fan 5 in the side of face shield 2, filter 4 is by nonwoven layer 8, carbon fiber layer 9, PP superfine fibre layer 10 and nonwoven layer 11 are arranged in order composition, its course of work is in the air intake filter device 4 by wind 5 machines, by filtering the back pure air is sent into formation malleation in the face shield 2, sent by steam vent 1 at last, respiratory resistance is smaller.
Claims (1)
1, a kind of electronic powered air-purifying formula dust mask, it comprises face shield, lead, filter, blower fan and the battery of being with steam vent, it is characterized in that being provided with filter and blower fan in the side of face shield, filter is arranged in order by nonwoven layer, carbon fiber layer, PP superfine fibre layer and nonwoven layer to be formed.
