The face shield of this utility model embodiment as shown in Figure 1, including mask body 10, headband 20, buckle 30.Mask body 10 is in order to covering, and headband 20 is in order to be fixed on mask body 10 on human body, i.e. mask body 10 is worn on human body head by headband 20.Headband 20 is connected and fixed on mask body 10 by buckle 30 is detachable, it is achieved that headband 20 and the detachable function of mask body 10, facilitates carrying and the replacing of headband of face shield, extends the bulk life time of face shield.

In the present embodiment, headband includes left headband, right headband, and one end of left headband is buckled in the left side of mask body 10, and one end of right headband is buckled in the right side of mask body 10, is and removably connects.The other end of left headband connection area formula detachable with the other end of right headband, adjustable connects.Optional left headband is connected by VELCRO with there being headband.

As in figure 2 it is shown, buckle 30 includes: keeper 31, it is fixed on mask body 10；Metal button member 32, one end is fixed on headband, the other end and keeper snapping.

Further, keeper 31 includes connecting plate 311, snapping plate 312.Connecting plate 311 is fixed on mask body 10, preferably fixed form, and mask body 10 is one-body molded when, connecting plate 311 embeds and is fixed on mask body 10.

Snapping plate 312, connects with the side of connecting plate, and snapping plate includes that an open slot 3121 run through is in order to fixing metal button member.Preferably, snapping plate 312 is formed in one with connecting plate 311.

Metal button member includes, fixing axle 321, cantilever 322, linking arm 323.Fixing axle 321 is fixed on headband, i.e. the above-below direction all around at fixing axle 321 fixed, non-movable, or only can fine motion within the specific limits.Fixing axle 321 can self adaptation wearer's shape of face and wearing mode realization rotation, the comfortableness that raising is worn.

Cantilever 322, for snapping keeper, the open slot 3121 of the shape size of cantilever 322 and snapping plate 312 is to mating, and open slot 3121 is used for accommodating cantilever mounted 322.

Linking arm 323, cantilever the first end is fixed on fixing axle by linking arm, is provided with space 324 so that cantilever can wear is fixed on keeper, i.e. facilitates cantilever to be inserted in open slot 3121 between the second end and the fixing axle of cantilever.

Linking arm 323, cantilever three fix axle 321 and form approximation n font.

Further, the second end of cantilever is provided with the limited block 3221 of fixed mount, and fixing axle is provided with the spacing arc 3211 of cantilever away from the side of linking arm.Limited block 3221, spacing arc 3211 coordinate clamping button fishplate bar 312 together.

Groove 3122 it is provided with fixing metal button member on the inwall of open slot one end.When cantilever enters open slot, slides into groove location, limited block 3221 blocks groove 3122, and spacing arc 3211 is at the outside squeeze buckle fishplate bar of snapping plate 312, and in the process, buckle sends the prompting sound that puts in place.

If connecting plate is provided with through hole 3111, when mask body molding, the raw material of mask body is full of through hole 3111, and after molding, throughhole portions is integrally forming with mask body, and connecting plate is firmly fixed to mask body.

Connecting plate width along away from snapping plate direction become big, approximate trapezoid, after mask body molding, desirably prevent connecting plate and depart from from mask body.

Further, headband is provided with ear hole for being socketed human body ear.Left and right headband, face shield is relative with human body ear after the wearing locates, and has an ear hole that can accommodate human body ear.The contact area increasing headband and human body head can strengthen wearing comfort, arranges ear hole and prevents headband from extruding external ear, and headband is hung on human body external ear by ear hole, prevents from coming off.

Improving embodiment further as face shield, mask body also includes purification assembly, and purification assembly includes: fixed mount, filter element, check valve.The domed shape of fixed mount, is used for fixing filter element, and contributes to the sizing of face shield.Specifically, can be formed by irregular ring or oval hoop one side bending, to adapt to human body shape of face.

Filter element, for filtering the air that human body sucks, solves common mask and can not effectively cross the problem of air filtering, and the filter element of the present embodiment is dismountable is fixed on fixed mount, facilitates filter element replacing.Check valve, is fixed on fixed mount to prevent exhaled gas from flowing back into human body mouth and nose.It is arranged on fixed mount the miniaturization contributing to face shield, facilitates the dismounting of filter element, efficiency of assembling during to improve production, and reduce user assembled difficulty in follow-up use.Specifically, check valve partially or completely penetrates fixed mount, and optimum position is fixed mount center or the position in fixed mount alignment human body nostril.

Improving embodiment further as filter element, filter element is arranged in order is formed by the first scrim layer, electrostatic cotton layer, antibacterial nonwoven cloth made layer, the second scrim layer.Filter element each layer shape is identical, is only that thickness is variant with material, and each layer abuts, and facilitates each layer to change.Offer through hole in the middle part of filter element to dock check valve, be i.e. the first scrim layer, electrostatic cotton layer, antibacterial nonwoven cloth made layer, the second scrim layer hole that all offers same shape in same position.Alternatively, check valve passes each layer of filter element, plays the effect spacing to filter element, and prevents filter element from disturbing human exhaled breath.

Improving embodiment further as face shield, mask body is a holding tank, and the profile of holding tank adapts with human body mouth nose.Holding tank rear end is the opening that opens wide completely for wearing, front end is provided with textured blow vent and circulates for air.Holding tank back edge is provided with flanging, flanging is that the extension bending of holding tank rear end face forms, flanging and back edge junction are the connecting portion that bending degree is variable, flanging forms the loose slot of variable volume with holding tank back edge, therefore when flanging and human contact, there is certain elasticity, to adapt to the shape of face of different user and to strengthen comfortableness, and can be more airtight laminating human face, effectively prevent gas leakage, affect mask protection filter effect.Holding tank inwall is provided with an annular stopper slot for being fixed for the purification assembly of face shield.The shape of stopper slot is mutually matched with fixed mount.Mask body is provided with ventilation net.Ventilation net is assemblied in stopper slot, after reassemble fixed mount, ventilation net has preliminary filtering function, and the function moulding to mask body, in order to strengthen wearing comfort, mask body have employed flexible material, but flexible material easy deformation plasticity is the best, the easy deformation of textured blow vent that therefore front end of holding tank is arranged, cause decorative pattern deformation to lose aesthetic feeling, the effect it being played support by ventilation net, prevents blow vent decorative pattern torsional deformation.

In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " exemplary embodiment ", " example ", " concrete example " or " some examples " etc. mean to combine embodiment or Specific features, structure, material or feature that example describes are contained at least one embodiment of the present utility model or example.In this manual, the schematic representation to above-mentioned term is not necessarily referring to identical embodiment or example.And, the specific features of description, structure, material or feature can combine in any one or more embodiments or example in an appropriate manner.

Embodiment the most of the present utility model, it will be understood by those skilled in the art that: these embodiments can carry out in the case of without departing from principle of the present utility model and objective multiple change, revise, replace and modification, scope of the present utility model is limited by claim and equivalent thereof.
