Description

A kind of mouth mask with bridge of the nose folder

Technical field

The invention belongs to breathing apparatus field, be specifically related to a kind of mouth mask with bridge of the nose folder.

Background technology

At present, the mouth mask major part that prior art uses does not possess nose clip or nose frame, bring rear sealing effectiveness poor, comfortableness is also poor, recently, there is a kind of mouth mask possessing nose-bridge frame on the market, this nose-bridge frame is similar to the nose-bridge frame on glasses, and comfort level is poor, and gas easily all exists situation about can not fit completely from the profile of top and nose, gas can enter without any filtration excessively, reduces the effect that mouth mask has isolation and filters.

Summary of the invention

The object of this invention is to provide a kind of mouth mask with bridge of the nose folder, solve above-mentioned one or multiple of the prior art.

A kind of mouth mask with bridge of the nose folder provided by the invention, comprise cover body, cover body is provided with the filter running through cover body, and cover body is provided with bridge of the nose folder near the position of upper edge.

A kind of mouth mask with bridge of the nose folder provided by the invention, is filtered pernicious gas by filter, and bridge of the nose folder can the position of fixed enclosure effectively, makes cover body closely be affixed on face.

In some embodiments, bridge of the nose folder is " U " type shape plastic sheet, and its two ends are connected to the top edge of cover body all rotationally." U " type shape bridge of the nose folder is similar to human body bridge of the nose camber, meets ergonomics, because plastics have elasticity, can clamp the bridge of the nose very well again, prevent cover body from dropping.

In some embodiments, cover body is provided with axial symmetry impression, and the both ends of bridge of the nose folder lay respectively at the both sides of axial symmetry impression.

In some embodiments, cover body also offers multiple penetrating pore, gas cell distribution is in the surrounding of filter.Pore is complementary discharges the air of characteristics of contaminated respiratory droplets in cover body.

In some embodiments, cover body also offers many exhaust ducts, and exhaust duct is distributed in around pore.The large area that exhaust duct is conducive to breath is discharged.

In some embodiments, filter bits is in the both sides of axial symmetry impression, and the lower filter cover that filter comprises filter cover and is flexibly connected with upper filter cover, is folded with filter cotton layer between upper filter cover and lower filter cover.Filter is used for the pollutants such as the harmful dust in filtered air.

In some embodiments, have the first through hole in the middle of upper filter cover, upper filter cover has multiple filter opening along the first through hole circumference.Set up multiple filter opening and can increase suction air capacity.

In some embodiments, upper filter cover is provided with dop relative to the junction of upper filter cover and lower filter cover, lower filter cover is provided with bayonet socket relative to the junction of upper filter cover and lower filter cover, and dop and bayonet socket match.By the mode that dop and buckle can fix, be convenient to change filter cotton layer.

In some embodiments, the both sides of cover body have extended back cover body band, and the afterbody of cover body band is provided with magic tape.Cover body band can be and human body back of head, and for fixed enclosure, magic tape can folding repeatedly.

Fig. 2 is the structural representation of the filter of a kind of mouth mask with bridge of the nose folder of the present invention.

Detailed description of the invention

The invention provides a kind of mouth mask with bridge of the nose folder, below in conjunction with the drawings and specific embodiments, the present invention described in detail:

As shown in Figure 1-2, a kind of mouth mask with bridge of the nose folder provided by the invention, comprise cover body 1, cover body 1 is provided with the filter 2 running through cover body 1, and cover body 1 is connected with bridge of the nose folder 3 near the position of upper edge, cover body 1 is provided with axial symmetry impression, bridge of the nose folder 3 is one " U " type shape plastic sheet, the two ends of bridge of the nose folder 3 lay respectively at the both sides of axial symmetry impression, and near axial symmetry impression place, the both ends of bridge of the nose folder 3 are rotationally connected with on cover body 1 by rivet.Because bridge of the nose folder 3 can rotate along rivet, and then bridge of the nose folder 3 is adjusted to the angle of the most comfortable.

Cover body 1 adopts three layers of medical adhesive-bonded fabric to form, and is connected and fix between each layer medical adhesive-bonded fabric by pressing.On cover body 1, the both sides of axial symmetry impression have and filter running-on 11, and filter 2 is sheathed on and filters on running-on 11.The both sides of cover body 1 have extended back cover body band 12, and cover body band 12 can lie in the rear portion of human body head, and cover body 1 entirety is fixed on human body face, and in the present embodiment, cover body band 12 afterbody is provided with magic tape, for being fixedly connected with between two cover body bands 12.

Filter 2 comprises filter cover 21 and lower filter cover 22, and upper filter cover 21 is articulated with lower filter cover 22, accompanies the filter cotton layer for filtering noxious gas between upper filter cover 21 and lower filter cover 22.Have the first through hole 211 in the middle of upper filter cover 21, upper filter cover 21 has nine filter openings 212 along the first through hole 211 circumference.The second through hole 221 is had in the middle of lower filter cover 22.

Upper filter cover 21 is provided with dop 210 relative to lower filter cover 22 with lower filter cover 22 hinged place, and lower filter cover 22 is provided with bayonet socket 220 relative to upper filter cover 21 with lower filter cover 22 hinged place, and dop 210 and bayonet socket 220 match.Like this by dop 210, bayonet socket 220, upper filter cover 21 can cover mutually with lower filter cover 22, and dop 210, bayonet socket 220 are a kind of dismountable fixing modes, are convenient to change the filter cotton layer be sandwiched between filter cover 21 and lower filter cover 22.
