Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of improvement anti-dust respirator, comprises a watt shape cover body 1, and the convex portions of wherein said watt of shape cover body 1 is towards front, and described watt of shape cover body 1 has air-vent, and described watt of shape cover body 1 is provided with connector 7, wears for end user.The front end of described watt of shape cover body 1 or rear end were provided with filter core 2, crossed filter core 2 for filtering extraneous courteous pollutant.The rear end of described watt of shape cover body 1 is provided with soft barrier film 3, and wherein a watt shape cover body 1 adopts harder material, and soft barrier film 3 is the softer and good material of sealing of employing.The left and right end of described soft barrier film 3 is connected with a watt straight line for shape cover body 1 left and right end respectively, and the upper and lower end of described soft barrier film 3 is connected with a watt arc-shaped side for shape cover body 1 upper and lower end respectively.Between watt shape cover body 1 and soft barrier film 3, form a relatively airtight cavity, the edge of soft barrier film 3 will ensure to be closely connected and to there is no crack with watt shape cover body 1, specifically can adopt the mode such as adhesive, welding to engage.In described soft barrier film 3, have membranes pores 31, passing through filter core 2 filtered airs can only enter by membranes pores 31, and therefore membranes pores 31 must be enough large, at least will enough allow the nostril of wearer and face breathe freely.
The front end of described watt of shape cover body 1 is provided with a watt shape face shield 4, on described watt of shape face shield 4, has pore, and the described filter core 2 of crossing is between watt shape cover body 1 and watt shape face shield 4, and such watt of shape face shield 4 just can play the effect of fixing and protecting filter core 2.As a preference, the upper and lower end of described watt of shape cover body 1 is respectively arranged with horizontal supporting plate 12, the upper and lower end of described soft barrier film 3 is connected with the horizontal supporting plate 12 of upper and lower end respectively, horizontal supporting plate 12 not only can improve a watt structural strength for shape cover body 1, and being connected of convenient and soft barrier film 3, further ensure air-tightness.As a preference, described horizontal supporting plate 12 is towards a watt front for shape cover body 1, the left and right end of described watt of shape cover body 1 is respectively arranged with vertical support plate 13, described watt of shape cover body 1, the horizontal supporting plate 12 of upper and lower end and the vertical support plate 13 of left and right end are combined to form a watt of shape cavity, the described filter core 2 of crossing is arranged in a watt shape cavity, facilitated the installation of filter core 2, and vertical support plate 13 also can make watt shape cover body 1 perpendicular edge be connected better with soft barrier film 3, further ensure air-tightness.
In the time of actual production, can, first with making watt shape cover body 1 shape out, then put soft barrier film 3 at a watt shape cover body 1, and open membranes pores 31 in the middle of soft barrier film 3, then load onto filter core 2 at a watt shape cover body 1.Filter material is general softer, and therefore the soft or hard of mistake filter core 2 or elasticity depended on the frame material used of filter core 2.
The described filter core 2 of crossing is designed to be folding wavy, crosses filter core 2 and is designed to folding wavy while bending, to coordinate a watt shape for shape cover body 1.The wherein said folding ripple 21 of crossing filter core 2 distributes along vertical direction, so not only can improve the filter effect of filter core 2, and improved filter core 2 can bending degree, made fit the better shape of watt shape cover body 1 of filter core 2.
The edge of described membranes pores 31 is provided with stiffening ring 32, reduces the chance of the membranes pores 31 places breakage of soft barrier film 3, specifically can be by membranes pores 31 crimpings are rolled out to a stiffening ring 32, or realize at the sticky stiffening ring 32 of membranes pores 31.
With reference to Fig. 3, as another embodiment, the rear end that the upper end of described watt of shape cover body 1 is provided with the wherein said upper bed course 5 of bed course 5 has the bridge of the nose groove 51 for the bridge of the nose.The lower end of described watt of shape cover body 1 is provided with underlayer 6, and the rear end of wherein said underlayer 6 has the chin groove 61 for chin.Upper bed course 5 and underlayer 6 coordinate the effect that can play the soft barrier film 3 of protection, but also facilitate mouth mask location, avoid mouth mask after being worn, to occur displacement.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
Through facts have proved, the utility model matches by watt shape cover body 1 and soft barrier film 3, utilizes harder watt shape cover body 1 to ensure the structural strength of mouth mask, utilizes soft barrier film 3 to improve the air-tightness of mouth mask simultaneously.Known through test, the leak rate of this mouth mask is lower than 1%, and airtight effect is very obvious.
