The purpose of this utility model provides a kind of good dustproof effect, dust mask easy to use.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of dust mask, it is characterized in that, comprise core pulling and filling system, air inlet pipe, escape pipe, tube connector, core pulling and filling system comprises the water bottle that changes on top, the water receptacle of bottom, changing water bottle and water receptacle is an integral body, change and be installed with horizontal division board in water bottle and the water receptacle, the air inlet pipe above-below direction passes the upper surface and the horizontal division board of core pulling and filling system, air inlet pipe is fixedlyed connected respectively with horizontal division board with core pulling and filling system, and escape pipe passes the upper surface of core pulling and filling system, the fixedly connected tube connector in escape pipe upper end, the other end of tube connector is fixedly connected with face shield, be fixedly connected with frenulum on the face shield, escape pipe, tube connector, face shield communicates respectively, and horizontal division board above-below direction also is fixedly connected with gas removing pipe.
The utility model has the advantages of and be: use the utility model, easy to carry, the convenient cleaning to the good purification of air, breathed also smooth and easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
A kind of dust mask, as shown in Figure 1, comprise core pulling and filling system 14, air inlet pipe 9, escape pipe 5, tube connector 8, what core pulling and filling system 14 comprised top changes water bottle 4, the water receptacle 2 of bottom, changing water bottle 4 is an integral body with water receptacle 2, change in water bottle 4 and the water receptacle 2 and be installed with horizontal division board 3, air inlet pipe 9 above-below directions pass the upper surface and the horizontal division board 3 of core pulling and filling system 14, air inlet pipe is fixedlyed connected respectively with horizontal division board 3 with core pulling and filling system 14, escape pipe 5 passes the upper surface of core pulling and filling system 14, the fixedly connected tube connector 8 in escape pipe 5 upper ends, and the other end of tube connector 8 is fixedly connected with face shield 6, be fixedly connected with frenulum on the face shield, frenulum can help the user with dust mask stable be fixed on face, escape pipe 5, tube connector 8, face shield 6 communicates respectively, and horizontal division board 3 above-below directions also are fixedly connected with gas removing pipe 1; In the present embodiment, the outer surface of core pulling and filling system is fixedly connected with hanged hook 11; In use, the use hanged hook hangs over waist with core pulling and filling system 14 or hangs over the suitable position of health, the convenient use; In the present embodiment, the lower end of air inlet pipe is fixedly connected with lower surface air separation cover 12 with holes, can make the air diffusion, and air is better purified; In the present embodiment, have exchanging water hole 13 on the core pulling and filling system, on the exchanging water hole 13 seal cover is installed, seal cover is corresponding with exchanging water hole 13, in the time of no at ordinary times, can do the wash by exchanging water hole; In the present embodiment, the junction of face shield 6 and tube connector 8 be equipped with vertical cube to protection network 7; In the present embodiment, be installed with non-return valve 10 in the air inlet pipe 9; Non-return valve can prevent aqueous reflux, and in the present embodiment, tube connector 8 is a telescoping tube, and telescoping tube can be regulated length as required; In the present embodiment, air inlet pipe 9 upper ends are connected and are connected to foraminous shield, can prevent effectively that bulky grain from entering air inlet pipe; In the present embodiment, tube connector 8 is threaded with escape pipe 5, and dismounting or easy for installation is easy to carry, the convenient use.
Earlier with clean water by the exchanging water hole core pulling and filling system of packing into, general water level is no more than waterline and get final product, fixing seal covers then, escape pipe and tube connector is connected again, and can use.The colliery worker directly is placed in head with frenulum when work, make face shield cover in face, when air-breathing, air enters core pulling and filling system by air inlet pipe, owing in the core pulling and filling system water is housed, and when air passes through water, air enters gas removing pipe after being purified by water, enter escape pipe then, to face shield, suck by the user by telescoping tube, during expiration, by the direct exhaust of face shield steam vent; After using, water can be dirty, opens exchanging water hole and clean and change water and get final product.
