Abstract
The front surface and the two sides of a nose-entering type dustproof mask are each provided with a round filter paper frame. The filter paper frames on the two sides are connected with noise entering tubes through a catheter. The noise entering tubes are made of medical silica gel. Inhalation valves are arranged between the noise entering tubes and the catheter. Exhalation valves are arranged on the other sides of the inhalation valves. The inhalation valves, the exhalation valves and the noise entering tubes are in a four-way state, and waste air exhaled from the exhalation valves is directly exhausted into a mask body and then exhausted out through the filter paper frame on the front surface. Inhaled fresh air enters nasal cavities from the filter paper frames on the two sides by means of the catheter, the inhalation valves and the noise entering tubes. Compared with the prior art, the nose-entering type dustproof mask can better guarantee the human health, and the waste air inside the mask body cannot be inhaled into the nasal cavities by people. The dustproof effect is better; since the exhalation valves are located in the mask body, the exhaled waste air is exhausted out of the mask body through the middle filter paper frames; and since the exhalation valves do not make contact with outside dust, the dust cannot enter the mask body at the switching moment of exhalation and inhalation.
Description
Technical field
The present invention relates to labour protection shield product field, is specifically exactly that one kind enters nose formula anti-dust respirator.
Background technology
At present anti-dust respirator mostly is face mask type, and it can protect the mouth and nose of people not encroached on by dust, but also have one disadvantage in that, is exactly that waste gas in mask can give people body health care belt to injure by people's suction；Without dust guard outside outlet valve, a small amount of dust can be entered in its moment closed, in addition because scope is larger at mask and facial contact, it is easy to which gap occur makes dust be sucked by people into mask, reduction dust-proof effect.
The content of the invention
To overcome the shortcomings of that prior art is present, the present invention provide it is a kind of will not make one to suck waste gas good dustproof effect in mask enter nose formula filter paper anti-dust respirator.
The object of the present invention is achieved like this, it is this enter nose formula filter paper anti-dust respirator main body be with mask made by rubber, above respectively there is a circular filter paper frame with both sides, both sides filter paper frame is connected into nasal tube by conduit, is entered nasal tube and is made up of medical silica-gel, is entered and have between nasal tube and conduit inlet valve, the opposite side of inlet valve is provided with outlet valve, inlet valve, outlet valve, enter nasal tube into four-way shape, the waste gas of outlet valve exhalation is directly come in mask, is discharged by filter paper frame above.The fresh air of suction is passed through conduit, inlet valve and is entered nasal tube to enter nasal cavity by the filter paper frame of both sides.
Present invention advantage compared with prior art：
First, the present invention compared with prior art, more can guarantee that health, and waste gas will not suck nasal cavity by people in mask；
2nd, the present invention compared with prior art, more preferably, because outlet valve is in mask, discharged outside mask dust-proof effect by middle filter paper frame, because outlet valve does not contact external dust, dust will not enter mask in the moment exhaled with enter gas shift by the waste gas of exhalation.
Description of the drawings
Below in conjunction with the accompanying drawings the present invention is elaborated with specific embodiment：
Fig. 1 is schematic structural view of the invention, and Fig. 2 is inlet valve of the present invention, outlet valve, enters nasal tube schematic diagram.
1, mask in figure；2nd, filter paper frame；3rd, conduit；4th, inlet valve；5th, outlet valve；6th, nasal tube is entered.
Specific embodiment
As shown in the figure it is this enter nose formula filter paper anti-dust respirator main body be with mask 1 made by rubber, above respectively there is a circular filter paper frame 2 with both sides, both sides filter paper frame 2 is connected into nasal tube 6 by conduit 3, enter nasal tube 6 to be made up of medical silica-gel, entering has inlet valve 4 between nasal tube 6 and conduit 3, the opposite side of inlet valve 4 is provided with outlet valve 5, inlet valve 4, outlet valve 5, enters 6 one-tenth four-way shapes of nasal tube, the waste gas of the exhalation of outlet valve 5 is directly come in mask 1, is discharged by filter paper frame 2 above.The fresh air of suction is passed through conduit 3, inlet valve 4 and is entered nasal tube 6 to enter nasal cavity by the filter paper frame 2 of both sides.
Claims (2)
1. it is with mask made by rubber that one kind enters nose formula filter paper anti-dust respirator main body（1）, it is characterised in that：Above respectively there is a circular filter paper frame with both sides（2）, both sides filter paper frame（2）By conduit（3）Connect into nasal tube（6）, enter nasal tube（6）With conduit（3）Between have inlet valve（4）, inlet valve（4）Opposite side be provided with outlet valve（5）, inlet valve（4）, outlet valve（5）, enter nasal tube（6）Into four-way shape, outlet valve（5）The waste gas of exhalation directly comes mask（1）It is interior, by filter paper frame above（2）Discharge, the fresh air of suction by both sides filter paper frame（2）By conduit（3）, inlet valve（4）With enter nasal tube（6）Into nasal cavity.
2. one kind according to claim 1 enters nose formula filter paper anti-dust respirator, it is characterised in that：Enter nasal tube（6）It is made up of medical silica-gel.
