Utility model content

The technical problem to be solved by the present invention is to provide one kind being only covered in nose, does not feel to feel oppressed after putting on, energy It enough effectively prevent dust in air to enter lung by respiratory tract, while playing the mask eyeshield dust-proof nose of protection face and eye Cover.

In order to solve the above technical problems, a kind of mask eyeshield anti-dust nose mask of the utility model includes that filter and nose are solid Determine device, filter is hollow structure, inside be filled with filter medium, filter it is outside shell is installed on one side, it is above-mentioned Outer casing bottom offers air discharge duct, and the inside one side of filter is equipped with nose fixing device, frenulum is fixed on filter, in mistake The side of filter is evenly equipped with multiple circumferential air admission holes, and inlet channel is offered at the center of filter, inlet channel it is outside one End is gas outlet, and the outside one side of filter is equipped with the catch that can all cover gas outlet, and catch is fixed on one side Edge in gas outlet is provided with multiple air admission holes on the side wall of inlet channel, and above-mentioned nose fixing device and people's nose fit Have seal washer made of flexible material on one side.

The shape of the filter and nose fixing device is oblate column as a further improvement of the utility model, Body.

As the further improvement of the utility model, the diameter of multiple circumferential air admission holes on the filter is 0.5mm。

As the further improvement of the utility model, the filter medium filled in the filter is activated carbon.

In use, the utility model mask eyeshield anti-dust nose mask is fixed on head with frenulum, keep the eyeshield of this mask dust-proof The filter of nose cup is fixed on nose, since the seal washer in nose fixing device has effectively filled up nose fixing device knead dough Gap between portion, when sucking gas, air enters from the circumferential air admission hole on filter periphery in filter people, then After filter medium is sufficiently cleaned up, nose, in this process, mistake are entered by the air admission hole on the inlet channel in filter The catch of the outside one side of filter tightly covers on gas outlet due to forming negative pressure, catch in inlet channel, makes air It cannot directly enter from gas outlet, filter can only be entered by the circumferential air admission hole of filter periphery, air is in filter Turned one it is curved, can fully and filter medium contact, good purification.

When exhaled gas, original negative pressure disappears people in inlet channel, and air-flow is directly gone out from inlet channel, gas Stream pushes catch, makes to form gap between catch and gas outlet, air-flow is quickly arranged by gas outlet from the air discharge duct of outer casing bottom Go out, keep human body sensory comfortable, and the utility model only needs to be covered in nose, oral area is exposed to outside, and user will not feel Feel oppressed.

Facial effect is protected to play, protective face mask is installed between the filter and nose fixing device, on The occasion that protective face mask is suitable for carrying out electric welding field and cutting operation is stated, the dust in filtration operation environment is simultaneously again to face Play protective action.

As being further improved for above structure, above-mentioned protective face mask upper end can also be fixed with goggles, due to this Utility model is fixed on head with frenulum, convenient and practical to free both hands for processing operation.
