Abstract
The utility model discloses a composite layer structure of a mask and belongs to the technical field of masks for breath protection. The utility model comprises gauze in an outer layer, an elastic tying belt that is hanged in the ear part or behind the head part and a filtering block in an inner layer, wherein, the gauze and the filtering block are rectangle parts that cover over mouths and noses. The utility model is characterized in that the filtering block comprises a polypropylene filtering film and a short fiber layer of terylene, rims of which are connected by an ultrasonic welding method, the upper and lower ends of the rectangle parts that cover over mouths and noses are folded inwards to form rumples, thus leading center of the rectangle parts that cover over mouths and noses to protrude forwards when worn, and a nose clamp with freely adjustable shapes is arranged inside gauze in an inner layer of the mask. The utility model adopts ultrasonic welding to connect composite layers of the mask, thus having beautiful appearance and close jointing, and a central filtering layer is made of the polypropylene filtering film and the short fiber layer of terylene and replaces traditional gauze masks, thus saving use of organdie products, and simultaneously the polypropylene filtering film can purify particulates efficiently, the middle part of the mask of the utility model is folded inwards, thus leading the utility model to be processed conveniently and placed approximately neatly, and to protrude outwards when in use with comfortable wearing.
Description
Technical field
The utility model belongs to respiratory protection mask technical field, is specifically related to have multi-layer combined filter body mouth mask.
Background technology
In manufacturing industry production, hospital and daily life, there are many particles and sensibiligen in the air, in order to stop particulates such as dust, pollen, bacterium, virus, wear cotton cloth respirator usually.Mouth mask of the prior art adopts gauze mostly, and protection effect is poor, and the difficult closely stickup of cotton gauze, and outward appearance is not attractive in appearance.
Summary of the invention
Poor in order to overcome existing mouth mask protection effect, the inaesthetic problem of outward appearance, the utility model provides a kind of comfortable wearing, mouth mask lamination layer structure that dust proof rate is high.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lamination layer structure of mouth mask, comprise outer field gauze, hang over ear or occipital elastic frenulum and internal layer filter block, gauze and filter block are rectangular mouth and nose covering portion, it is characterized in that filter block comprises with ultrasonic wave welds polypropylene filter membrane and the polyester staple fiber layer of method with periphery, the upper and lower side of mouth and nose covering portion inwardly is folded to form gauffer, the center of mouth and nose covering portion is protruded forward when wearing, in mouth mask internal layer gauze, also be provided with the nose clip that arbitrarily to adjust profile.
Described polypropylene filter membrane is that polypropylene filter material melts and sprays and gets, and thickness is 20～50g/m
2
Needle point method processing gets described polyester staple fiber layer to melt and spray for nonwoven, and thickness is 100～200g/m
2
Described nose clip is the soft metal silk or the cable of plastic packaging.
There is a slice polypropylene filter membrane the inboard of described mouth and nose covering portion, welds method identification marking literal or figure with ultrasonic wave on it.
The utility model is with respect to existing Respirator structure, and beneficial effect mainly shows: 1 adopts ultrasonic bonding that the composite bed of mouth mask is engaged, and appearance looks elegant is fitted closely; 2, adopt polypropylene filter membrane and polyester staple fiber to make the center filtering layer, substitute traditional cotton cloth respirator, saved the cotton goods consumption, the polypropylene filter membrane can efficiently purify particulate simultaneously, when mean particle dia 0.27～0.42 μ m, than speed at 0.06～0.804L/min.cm
2The time, purification efficiency is 98.5～99%; 3, nose clip is established in mouth mask inside, and is arbitrarily moulding during use, makes mouth and nose and air outside only pass through filter block; 4, the filter block middle part is inwardly folding, easy to process, and approximate smooth when depositing, use can be to outer lug, comfortable wearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the profile at Fig. 1 I place.
Fig. 3 is the A place enlarged drawing of Fig. 2
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～mouth mask shown in Figure 3, the mouth and nose covering a of portion is made up of the filter block of cotton gauze 1 and internal layer, sews up around the mouth and nose covering a of portion, is fixed with at the left and right sides upper and lower side and hangs over ear or occipital elastic frenulum 2.
Filter block comprises the polyester staple fiber layer of 1～5 strata propylene filter membrane and 1～5 layer.
Outer field gauze 1 adopts 21～32 cotton bleached gauzes, density longitude and latitude 30～40 (one-inch root), and the parcel filter block, gauze can be established two-layer, protection internal layer filter block, cotton gauze absorbing sweat ability is strong, and is harmless to human body skin, reusable.
Filter block comprises that also mouth mask cloth is polyester staple fiber layer 4, can be located at innermost layer, and nonwoven gets to melt and spray needle point method processing, and thickness is 100～200g/m
2Polyester staple fiber layer 4 plays about protection polypropylene filter membrane 3 and resistance dirt, and it can thicken mouth mask warmingly simultaneously, because mouth mask cloth is the polyester staple fiber layer, also can bond preferably to other layer.
It is bonding firmly with periphery that the multilayer of filter block welds method with ultrasonic wave, is loaded in the gauze and sews up.Nose clip 5 is located at mouth mask internal layer middle upper part, adopts CABLE MATERIALS and No. 22 iron wires to make, and can arbitrarily adjust profile.
Mouth and nose covering portion is a rectangle, and the upper and lower side of mouth and nose covering portion inwardly is folded to form gauffer 6, sees the folding mode of Fig. 2, sews up with cotton thread around the mouth mask, and protrude forward at the center of mouth and nose covering portion when wearing.
In the gauze, the polypropylene filter membrane in that central authorities of mouth and nose covering portion also can establish a fritter welds the printable trade mark of method, trading company or other pattern with ultrasonic wave.
Claims (5)
