Above-mentioned three-dimensional filter, filter layer of cloth laminates conjunction by some metafiltration layer of cloths and forms, and ring filter layer of cloth periphery is provided with the ring limit that heat is compounded to form.Filter layer of cloth laminates conjunction by some metafiltration layer of cloths and forms, and can increase the number of plies according to different protection level.The ring limit be compounded to form through heat and the shape in buckle stage suitable, convenient between outer shroud frame and inner becket sealed card link and connect.
Above-mentioned three-dimensional filter, filter layer of cloth entirety becomes cover body shape, and trailing flank forms inner cavity.Inner cavity forms mouth mask and inhales respiratory cavity requisite space, compresses the space shared by it, effectively reduces the thickness of mouth mask entirety, increases filter area simultaneously thus expands into side's amount and the technique effect reducing air intake resistance.
Above-mentioned three-dimensional filter, filter layer of cloth comprises sterilization ply of paper, active carbon layer, HEPA filter paper layer and nonwoven layer is stacked is compounded to form.The technique effect that high efficiency composition filter paper effectively filters air.
Above-mentioned three-dimensional filter, the medial surface of ring inner becket is provided with positioning convex.Be combined with inner becket thickness by projection, thickeied the technique effect of the thickness on buckle limit.
The utility model is owing to adopting technique scheme, posting logical location loop order sealed card clip establishes filter layer of cloth in wherein, filtering bodies is located at leading flank by its posting attaching type seal buckle, three-dimensional filter layer of cloth expands into side's amount and reduces air intake resistance while guarantee filter effect, the load of motor, wind wheel air-supply noise and the limitation of wind wheel off-centre operation have been fallen at the end, increase air output, reduce battery electric quantity and use thus the time extending battery operation.Be fastened on by outer cover in the air intake passage formed on front side of cover body, the outer shroud frame that phase buckle connects as one and the buckle-type modular design of inner becket have the technique effect of sealing, fixing-stable, easy disassembly.Clamp connection structure realizes the anti-fine particle of sealing, facilitate each parts production and processing and dismounting, realized the technique effect of easy disassembly by outer shroud frame, inner becket and filter layer of cloth three sealed clamps structure, and to realize and the sealing contact surface being connected gap between cover body amasss the technique effect realizing sealing anti-fine particle and enter.
A kind of air-purifying respirator, is provided with the air inlet of filter chamber and filter chamber, is provided with described three-dimensional filter along seal buckle in the filter chamber of air inlet in cover body.
The 3d air delivery mouth mask applying above-mentioned wind wheel compared with prior art has to be breathed smooth and easy, and protection effect is good, has the advantage that structure is simple, reasonable in design simultaneously.Especially for the filter protection of fine particle (PM2.5).The load of motor, wind wheel air-supply noise and the limitation of wind wheel off-centre operation have fallen at the end in the centrifugal air-supply in center, increase air output, reduce battery electric quantity and use thus the time extending battery operation; Buckle-type modular design has the technique effect of fixing-stable, easy disassembly.Have breathing smooth and easy, what protection effect was good waits technique effect simultaneously.
