Description
Technical field
A kind of mouth mask is the utility model is related to, is specifically a kind of preforming no nose clip children haze mouth mask.
Background technology
With industrial expansion, air pollution problems inherent is increasingly severe, and the harm of haze is also increasingly known by people.
The haze serious date, out of doors when, wear haze (anti-Pm2.5) mouth mask turn into many people selection.
A effective haze mouth mask need to meet two most basic conditions：First, filter efficiency, filter efficiency is necessary
Reach certain value, as 90% and more than, requirement could be met；Second, the stickiness of mouth mask and face, only mouth mask are with wearing
The shape of face of wearer has good fitting, is just avoided that the risk revealed during wearing.And study and show it is to be most difficult to realize patch at the bridge of the nose
The place closed and leaked.Most of haze mouth mask on the market is designed for adult at present, according to adult
Shape of face carry out the design of corresponding shape of product and structure, be employ being designed to deal with for nose clip mostly the configuration aspects
The problem being bonded at the bridge of the nose.It is this to there is nose clip design to be also used on some commercially available children's haze mouth masks but real due to youngster
The reason for virgin bridge of the nose is more flat and tender, this nose clip design do not get a desired effect in actual use.
Although also there is the so-called children's haze mouth mask of some patent shows, it address only children and wears just
The problem of profit and filter efficiency, and for how with children's shape of face it is closely sealed especially closely sealed at the bridge of the nose the problem of not very
Good solution.
Utility model content
The purpose of this utility model is to provide a kind of preforming no nose clip children haze mouth mask, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of preforming no nose clip children haze mouth mask, including the preforming nasal cushion of mask body, 3D and adjustable mouth mask
Ear band, the mask body left and right sides are respectively provided with an adjustable respirator ear belt, and mask body bosom position is provided with 3D
Preforming nasal cushion；The mask body is made up of three layers of non-woven fabrics, is followed successively by surface structure non-woven fabrics, internal layer melt-blown from outside to inside
Filtering non-woven cloth and internal layer soft nonwoven；The preforming nasal cushion of 3D is made of nontoxic expanded material；It is described can
Regulation respirator ear belt includes knitted elastic headband and thermoplastic elastomer (TPE) adjusting button, and knitted elastic headband passes through thermoplastic elastomer (TPE)
Adjusting button.
As further program of the utility model：Surface structure non-woven fabrics uses 40g/m2-80g/m2The polypropylene of grammes per square metre
Spun-bonded non-woven fabrics material.
As further program of the utility model：Internal layer melt blown filter non-woven fabrics is the polypropylene melt-blown that Electrostatic Treatment is crossed
Non-woven fabrics, the melt spraying non-woven fabrics are more than 90% in wind speed 0.14m/s for 0.3 micron of particulate matter filter efficiency.
As the utility model further scheme：The internal layer soft nonwoven selects 30-70g/m2Grammes per square metre is gathered
Lactic acid non-woven fabrics or polypropylene non-woven fabric are made.
As the utility model further scheme：The preforming nasal cushion of 3D is 35kg/ m from expansion density3-
50 kg/ m3Polyurethane foam material or polyethylene foam-material.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, can
With highly closely sealed with children's shape of face, there is more preferable protection effect, provide in haze weather to children and be really effectively protected.
