Technique effect of the present utility model is: it has good filtration effect, and not saturating dust uses comfortable advantage.
Description of drawings
Accompanying drawing is a sectional structure chart of the present utility model.
The specific embodiment
As shown in drawings, the dust mask of present embodiment comprises face shield 1, be located at the bandage 2 and the filter 3 of face shield 1 both sides, face shield 1 bottom and front portion are respectively equipped with inlet valve 4 and outlet valve 5, described filter 3 is by housing 6, central tube 7, filtering bodies 8 and bottom 9 are formed, housing 6 is the tubular body of " protruding " font for section, its shoulder plane is provided with pore 10, housing 6 is spirally connected with the inlet valve 4 of face shield 1 bottom, central tube 7 outer walls are fixed with baffle plate 11, be distributed with passage 12 on the baffle plate 11, central tube 7 places in the housing 6, path section in central tube 7 tops and the housing 6 is connected, filtering bodies 8 is enclosed within central tube 7 peripheries on baffle plate 11, and bottom 9 is screwed onto housing 6 bottoms.
Described central tube 7 bottoms are connected with covers 13, covers thoroughly and is provided with secondary filter body 14 in 13.
Described housing 6 is provided with sealing ring 15 with the junction of the inlet valve 4 of face shield 1 bottom.
Described bottom 9 is a goblet.
Described bottom 9 is provided with sealing ring 15 with the junction of housing 6.
In the present embodiment, baffle plate 11 is fixed by the ring platform that is provided with on central tube 7 outer walls, and baffle plate 11 can also be an one with central tube 7, also can connect by gluing other fixed form that waits.Path section connected mode in central tube 7 tops and the housing 6 adopts pegs graft, as adopts other connected mode, considers sealing needs, can take to increase mode such as sealing gasket or directly utilize the sealing ring 15 of housing 6 and inlet valve 4 junctions.
In the present embodiment, saturating lid 13 is plugged on central tube 7 bottoms, and secondary filter body 14 is a filter membrane, is pressed on central tube 7 bottoms by saturating lid 13. and secondary filter body 14 also can be materials such as cavernous body, directly be placed on winding covering, spacing by the card platform is set in central tube 7.
In the present embodiment,
The utility model also can increase the gas defence function by place filtering material in the bottom 9 of cup-shaped based on dustproof.Because the utility model good seal performance, its filter area is greater than common dust mask, so its dustproof effect and to wear comfortableness all good.
