Description

A kind of three-dimensional mask

Technical field

The utility model relates to a kind of three-dimensional mask, and this three-dimensional mask is used for preventing that the PM2.5 fine particle is inhaled in human body.

Background technology

PM2.5 refers to that diameter is less than or equal to the particle of 2.5 microns, PM2.5 in atmosphere is inhaled in human body and can damages health, prevent that the PM2.5 particle from being to wear masks to human injury's the simplest, effective method, the mouth mask of prior art is by the plane filter that arranges in the mouth mask interlayer, and the PM2.5 particle is filtered.But can filter the filter of PM2.5 particle, its institutional framework is very closely knit, exhales, the bad wearer of the large gas permeability of inspiratory resistance feels expiratory dyspnea, makes this kind mouth mask promote the use of difficulty.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of three-dimensional mask, and it can effectively filter the PM2.5 particle and have again gas permeability preferably.

the structure of this three-dimensional mask comprises filtering bodies, wrap the outer cover 7 of filtering bodies, be connected to the frenulum 12 on outer cover, it is characterized in that: described filtering bodies comprises skeleton and crosses filter ruffle, described skeleton has along the radian of human body face bending, it comprises the transverse slat 1 of strip, bottom surface at transverse slat, vertically be provided with some rectangular-shaped risers 2, be connected with gripper shoe 3 between adjacent riser, described gripper shoe 3 is positioned at the upper position of riser, be evenly equipped with some through holes on the plate face of described riser 2 and gripper shoe 3, be provided with symmetrically two respiratory siphons 6 that can fill in the human body nostril in the middle position of transverse slat, one end of respiratory siphon 6 puts in the cavity 4 that riser 2 and gripper shoe 3 surround, the described filter ruffle of crossing is made by the fabric that can filter PM2.5, its inner surface is arranged along the surface of described transverse slat, riser and gripper shoe, cross and be provided with isolating bar 5 between the filter ruffle surface relative with riser and make it to leave gap, cross the filter ruffle part surface relative with gripper shoe and be fixed on gripper shoe.

The planar dimension of this three-dimensional mask is suitable with the planar dimension of existing mouth mask, but its contact area of crossing filter ruffle and atmosphere is far longer than the filter of existing mouth mask and the contact area of atmosphere, thereby has effectively improved the gas permeability of mouth mask; This three-dimensional mask is provided with respiratory siphon can make the air that enters human body for purifying air after filtering, and has improved the effect that anti-fine particulates pollutes.

The specific embodiment

The existing accompanying drawings specific embodiment of the present utility model.

the structure of this three-dimensional mask the first embodiment comprises filtering bodies, wrap the outer cover 7 of filtering bodies, outer cover is strong by quality, abundant fabric is made, be connected to the frenulum 12 on outer cover, it is characterized in that: described filtering bodies comprises skeleton and crosses filter ruffle, described skeleton has along the radian of human body face bending, it comprises the transverse slat 1 of strip, vertically be provided with two rectangular-shaped risers 2 in the bottom surface of transverse slat, be connected with gripper shoe 3 between adjacent riser, described gripper shoe 3 is positioned at the upper position of riser, be evenly equipped with some through holes on the plate face of described riser 2 and gripper shoe 3, be provided with symmetrically two respiratory siphons 6 that can fill in the human body nostril in the middle position of transverse slat, one end of respiratory siphon 6 puts in the cavity 4 that riser 2 and gripper shoe 3 surround, the described filter ruffle of crossing is made (as the polypropylene fibre melt spraying non-woven fabrics) by the fabric that can filter PM2.5, its inner surface is arranged along the surface of described transverse slat, riser and gripper shoe, cross and be provided with isolating bar 5 between the filter ruffle surface relative with riser and make it to leave gap, cross the filter ruffle part surface relative with gripper shoe 3 and be fixed on gripper shoe, cross the closed at both ends of filter ruffle.

When this mouth mask uses, respiratory siphon on mouth mask is filled in nostril, frenulum is drawn and hangs over ear, respiratory siphon is contacted with the nostril sealing, be pooled to cavity 4 through the first surface 8 of filter ruffle, the air-flow that second surface 9 filters by the through hole on riser 2 and gripper shoe 3 when air-breathing, enter human body by respiratory siphon again, the contrary direction that during expiration, air-flow is pressed inspiratory airflow through respiratory siphon is discharged or is directly discharged from mouth.

This three-dimensional mask adopts said structure, the first surface of filter ruffle was contacted with atmosphere with second surface, its area that contacts with atmosphere is equivalent to the contact area of four filters, greatly improved the gas permeability of mouth mask, be in the 85L/min situation at gas flow, the inspiratory resistance of mouth mask is 90～70Pa.Because respiratory siphon and nostril are that sealing contacts, the air that therefore can avoid polluting enters human body.

Reduce filter area and affect gas permeability for the surface that prevented filter ruffle and riser fit, described isolating bar 5 is separately positioned on the width two ends of transverse slat 1, the bottom of riser 2, at the middle part of riser, arranges equably 1～3.

For preventing that respiratory siphon from gliding, and be provided with an arcwall face 11 on described outer cover 7 tops, but this arcwall face cramping lived nose after described mouth mask is worn.

Described skeleton can form by Shooting Technique is whole, described filtration is applied mechanically the polypropylene fibre melt spraying non-woven fabrics and is made, first skeleton was inserted filter ruffle during assembling, to cross the second surface 9 of filter ruffle inserts between riser again, on the bottom surface of the bonding gripper shoe in top of second surface, then will cross the sealed at both ends closure of filter ruffle, put finally outer cover, and cross filter ruffle and outer cover and the contacted position of respiratory siphon and be pressed on the transverse slat of skeleton with tight loop 61 sealings.

Fixing for convenience of the second surface 9 of crossing filter ruffle and cross filter ruffle replacing, arrange a pair of deep-slotted chip breaker 51 in the bottom surface of gripper shoe, the top of crossing the second surface 9 of filter ruffle is embedded in described deep-slotted chip breaker by a columniform elastic layering 52.

, for convenience of the replacing of crossing filter ruffle and the cleaning of described outer cover 7, be provided with a slide fastener 13 or several snappers in the bottom of outer cover.

Structure and the first embodiment of second embodiment of this three-dimensional mask are basic identical, and difference is that described riser 2 quantity are three, and the described filter ruffle of crossing can form first surface 8, second surface 9 the 3rd surface 10, can further improve like this gas permeability of mouth mask.
