Abstract
A nose mask for cleaning the coming air by use of water or activated carbon is composed of the shell with external, upper, lower and back cavities, partition between external and upper cavities, filter layer between upper and lower cavities, barrier between lower and back cavities and air inlet tube, switch, sealing ring, exhaust window and barrier, carrying belt and bottom cover.
Description
One, technical field:
The present invention relates to protective device for respiration, particularly a kind of Wet-dry purifies nose cup.
Two, background technology:
The present protective device for respiration that uses, well-known is mouth mask, its shortcoming or deficiency are: (1) anti-dust performance is poor, possesses the gas defence performance hardly; (2) the breathing smoothness is poor, makes the people feel to feel oppressed; (3) influence people's communication.
Three, summary of the invention:
The objective of the invention is shortcoming or deficiency, provide a kind of performance Wet-dry good, comfortable, easy to use especially to purify nose cup at above-mentioned prior art existence.
Wet-dry of the present invention purifies nose cup, comprise housing, switch, sealing ring, exhausting window and exhaust screen, be linked with ring and bottom, it is characterized in that described housing is divided into exocoel, epicoele, cavity of resorption and back cavity, exocoel is separated by dividing plate mutually with epicoele, and epicoele is separated by filter screen and filtering layer mutually with cavity of resorption, and cavity of resorption is separated by the air inlet baffle plate mutually with back cavity, case top is installed air inlet pipe, following air intake duct and switch, front end is installed sealing ring, and front part sides is installed exhausting window, and bottom is installed in the bottom.
Wherein, described housing top and rear end are the structure of opening for the sealing of arched roof shape, front end; Described dividing plate front middle part is installed on to the projecting inward air intake duct of epicoele; Install filter screen and pressure pin between described epicoele and the cavity of resorption, install filtering layer between filter screen and the pressure pin; Install exhaust screen on the described exhausting window, itself and exhausting window are for flexibly connecting; Be provided with through hole between described cavity of resorption and the back cavity, install the air inlet baffle plate by bearing pin on it.Described upward air inlet pipe top is provided with the hemispherical air inlet and the filter screen of protrusion; Described switch is hemispherical structure, when pushing to, closes the air inlet pipe air inlet, opens down air intake duct, when leaving behind, closes down air intake duct, opens the air inlet pipe air inlet.Described switch cuts out down the air intake duct place, is provided with a leading edge and the corresponding to plane of hemisphere face in it; Installing filtering material in the described air intake duct down is as active carbon.
The present invention has following advantage compared with prior art:
1, the present invention has the characteristics of Wet-dry, injects clear water in cavity of resorption and epicoele, and with water-wet, anti-dust performance is good, as point salt or vinegar a little in clear water, also can have certain sterilization.The installing filtering material as active carbon, has filtration, purification and gas defence function in the following air intake duct;
Both prevent dust, poison gas when 2, wearing, do not influenced people's communication again, convenient and practical.
3, except that sealing ring by rubber make make by sponge with filtering layer, make by non-toxic plastic, wear very light comfortable.

Five, specific embodiment:
With reference to Fig. 1-Fig. 5, a kind of Wet-dry purifies nose cup, comprises housing 1, switch 2, sealing ring 17, exhausting window 18 and exhaust screen 19, is linked with ring 20 and bottom 14.Housing 1 is divided into exocoel 21, epicoele 15, cavity of resorption 16 and back cavity 22, exocoel is separated by dividing plate 7 mutually with epicoele, epicoele is separated by filter screen 9 and filtering layer 10 mutually with cavity of resorption, cavity of resorption is separated by air inlet baffle plate 12 mutually with back cavity, case top is installed air inlet pipe 5, following air intake duct 4 and switch 2, front end is installed sealing ring 17, and front part sides is installed exhausting window 18, and bottom 14 is installed in the bottom.Housing 1 top and rear end are the structure of opening for the sealing of arched roof shape, front end; Dividing plate 7 front middle parts are installed on to the projecting inward air intake duct 8 of epicoele 15.Install filter screen 9 and pressure pin 11 between epicoele 15 and the cavity of resorption 16, install filtering layer 10 between filter screen and the pressure pin.Install exhaust screen 19 on the exhausting window 18, itself and exhausting window 18 are for flexibly connecting.Be provided with through hole between cavity of resorption and the back cavity 22, install air inlet baffle plate 12 by bearing pin 13 on it.Last air inlet pipe top is provided with the hemispherical air inlet and the filter screen 3 of protrusion.Switch 2 cuts out air inlet pipe air inlet 3 when pushing to, and opens down air intake duct 4, when leaving behind, closes down air intake duct 4, opens the hemispherical structure of air inlet pipe air inlet 3.Close air intake duct place down at switch, be provided with a leading edge and its interior corresponding to plane of hemisphere face, be beneficial to the tight closing of switch 2.Installing filtering material in the following air intake duct 4 is as active carbon.The lower end of last air inlet pipe 5 is connected with back cavity 22, is connected by air inlet baffle plate 12 and cavity of resorption 16; Following air intake duct 4 is connected with exocoel 21 by hole 6.During use, get final product by being linked with to be linked with on ring 20 bolts.
During use, when leaving behind switch 2, following air intake duct 4 is closed, and goes up air inlet 3 simultaneously and opens, air sucks back cavity 22 through air inlet 3, through air inlet baffle plate 12, enter in cavity of resorption 16 water, behind filtering layer 10 and filter screen 9, enter epicoele 15, through air intake duct 8, suck for human body, the waste gas of exhalation is discharged by exhausting window 18 and exhaust screen 19 again.When pushing to switch 2, air inlet 3 is closed, this at present air inlet be opened the activated carbon filtration of air in following air intake duct, enter exocoel through air admission hole 6 and breathe for the people, water level should not have screen pack 9 but puts water in any case and should not be advisable from air intake duct 8 outflows at ordinary times.
