Description
One, technical field:
The utility model relates to protective device for respiration, and 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 purpose of this utility model is shortcoming or the deficiency that exists at above-mentioned prior art, provides a kind of performance Wet-dry good, comfortable, easy to use especially to purify nose cup.
Wet-dry described in the utility model 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 utility model has following advantage compared with prior art:
1, the utlity model has the characteristics of Wet-dry, inject clear water in cavity of resorption and epicoele, 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.
