Abstract
The utility model relates to an air feeding dustproof respirator, which is characterized in that a veil, a blower and a dust filtering head are orderly connected by a pipe and are carried with a dynamic system together. The utility model has the advantages that protection rate is high, air is fed by positive pressure, breath is influent, and labor is convenient vis using the air feeding dustproof respirator. The utility model is suitable for individual labor protection in the dust environment with high density.
Description
The utility model relates to a kind of dustproof respirator, belongs to the labour protection articles for use field.
In the production environment of dirt was arranged, the dustproof product of providing for labourer that protect mainly contained cotton cloth respirator, self-priming anti-dust respirator and long tube mask at present.In these several protective articles, its filter dirt part protection ratio is low, does not satisfy national industrial hygiene designing requirement.Its protection ratio is high, has inspiratory resistance big again, or carries long tube, makes the inconvenient deficiency of work.
The purpose of this utility model is to provide a kind of air-supply respirator that prevents dust, and it uses in the high density dust atmosphere, and the protection ratio height is arranged, breathe smooth and easy, the characteristics of easy to operate and not overslaugh work.
The technical solution of the utility model is: a kind of air-supply respirator that prevents dust, have face shield and conduit, it is characterized in that: the filter dirt head that is contained on the host shell is communicated with conduit and face shield by the blower fan in the housing, and the motor and the battery that drive blower fan also are housed in the housing, and housing is externally connected with belt.
The face shield of present technique is selected the face shield of market sale for use, and for example demifacet cover, simple eye face shield, eyes face shield etc. have outlet valve on the face shield.Filter dirt head and host shell, blower fan, motor are formed filtration fraction, and it carries out electronic exhausting filtration to the high density dust in the production environment, and the clean air after the filtration is delivered in the face shield by conduit under positive pressure, for air-breathing usefulness.The gas of breathing out is discharged by the outlet valve on the face shield.This host shell carries at one's side by belt, by the control of the power switch on housing machine operation.
Because electronic exhausting is filtered, its draft is big, can satisfy the requirement of high density filter dirt part, so the protection ratio height.Again because to the face shield forced draft, institute does not feel suffocated so that breathe smooth and easyly, and the circulation of air in the face shield makes facial nice and cool, comfortable.Being also advantageous in that of present technique: simple in structure, in light weight, and can carry, during than work in the past, long in tow conduit is compared below the face shield, is suitable for and convenient, welcome by the wearer.
Below in conjunction with description of drawings embodiment of the present utility model.
Accompanying drawing is the structural representation of a kind of dustproof respirator of blowing of the utility model.
In the host shell among the figure (1), blower fan (5), battery (11), motor (9) are housed, filter dirt head (4), charging socket (2) are equipped with in host shell (1) surface, switch (3), belt (10), the filter dirt head (4) with conduit (6) between be communicated with by blower fan (5), conduit (6) is connected on the simple eye full facepiece mask (8).This face shield can also be demifacet cover, eyes full facepiece mask.Outlet valve (7) is arranged on the face shield (8).
