Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of improvement anti-dust respirator, comprise a watt shape cover body 1, toward the front, described watt of shape cover body 1 has air-vent to the convex portions of wherein said watt of shape cover body 1, 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 are provided with filtration core 2, filtration core 2 for filter extraneous courteous in 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 then adopts the softer and good material of sealing.The left and right end of described soft barrier film 3 is connected with a watt straight line for the left and right end of shape cover body 1 respectively, the upper and lower end of described soft barrier film 3 is distinguished bending and is connected with a watt arc-shaped side for shape cover body 1 upper and lower end, the cavity that between described watt of shape cover body 1 and soft barrier film 3, formation one is relatively airtight, namely the edge of soft barrier film 3 will ensure do not have crack with watt shape cover body 1 compact siro spinning technology, and the mode such as adhesive, welding specifically can be adopted to engage.Have membranes pores 31 in described soft barrier film 3, namely can only be entered by membranes pores 31 through filtration core 2 filtered air, therefore membranes pores 31 is sufficiently 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, and described watt of shape face shield 4 has pore, and described filtration core 2 is between watt shape cover body 1 and watt shape face shield 4, and such watt of shape face shield 4 just can play effect that is fixing and protection filtration 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 connection that is convenient and soft barrier film 3, ensure air-tightness further.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, described filtration core 2 is arranged in a watt shape cavity, facilitate the installation of filtration core 2, and vertical support plate 13 also can make watt shape cover body 1 vertical edges be connected better with soft barrier film 3, ensures air-tightness further.
When actual production, can first with making watt shape cover body 1 shape out, then soft barrier film 3 on watt shape cover body 1 overlaps, and membranes pores 31 is opened in the middle of soft barrier film 3, then load onto filtration core 2 at a watt shape cover body 1.Filter material is generally softer, and therefore the soft or hard of filtration core 2 or elasticity depend on the material that the frame of filtration core 2 is used.
Described filtration core 2 is designed in folding wavy, namely filtration core 2 be designed to folding wavy while bending, to coordinate a watt shape for shape cover body 1.The collapsed corrugations 21 of wherein said filtration core 2 vertically distributes, and so not only can improve the filter effect of filtration core 2, and improve filtration core 2 can bending degree, filtration core 2 is fitted the shape of watt shape cover body 1 better.
The edge of described membranes pores 31 is provided with stiffening ring 32, reduces the chance of membranes pores 31 place's breakage of soft barrier film 3, specifically by rolling out a stiffening ring 32 to membranes pores 31 crimping, or realizes 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 can play the effect protecting soft barrier film 3, but also facilitates mouth mask to locate, and avoids mouth mask after being worn, occur displacement.
According to above-mentioned principle, the present invention can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the present invention 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 invention modifications and changes more of the present invention.
Through facts have proved, the present invention is matched 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 clearly.
