Abstract
The utility model relates to a filter element of the dustproof mask for increasing the filtration area and the dust containing capacity, which is a cone with a plurality of steps made of the filter materials with a surface much larger than the projection surface of the filter element. The diameter of the bottom of the cone is equal to the diameter of the filter element and the cone is folded along the steps and compressed to be a cylindrical filter element with a limited height provided with a plurality of the annular ripples. The extended surface of the cylindrical filter element is much larger than the projection surface of the filter element, which increases the filtration area and the dust containing capacity.
Description
Affiliated technical field
The utility model relates to a kind of filter of anti-dust respirator, especially can increase the anti-dust respirator filter element of filter area and dust containing capacity.
Background technology
At present, known anti-dust respirator filter element is by the material manufacturing with a large amount of micro gaps or micropore, when particulates such as dust, aerosol process filter element, just be blocked and be adsorbed on the filter element, avoid the user to suck the effect of these harmful substances thereby play.But, a lot of filter elements are subjected to the restriction of planar structure size and manufacturing process, shape generally is planar rondure or highly very little ripple is only arranged, filter area is less, and the quantity that can hold particulate is also less, under the identical prerequisite of filter element material, respiratory resistance is bigger, use behind the certain hour respiratory resistance also can very fast increase, breathe to the user and cause difficulty, must often change filter element.
Summary of the invention
In order to overcome existing filter element filter area and the less deficiency of dust containing capacity, the utility model provides a kind of filter element, this filter element can not only stop and adsorb particulates such as dust, aerosol, and increases filter area and dust containing capacity greatly under identical in the filter element material, as not increase the filter element planar dimension prerequisite.
The technical scheme that its technical problem that solves the utility model adopts is: the taper shape of an area being made several ladders much larger than the filtering material of filter element projected area, cone bottom diameter equals the diameter of filter element, along these ladders circular cone is folded and is compressed into the limited cylinder shape filtering element of height that a surface has some annular ripples.Because the long-pending projected area of the unfolded surface of this cylinder shape filtering element, thereby reach the purpose that increases filter area and dust containing capacity much larger than filter element.
The beneficial effects of the utility model are, can reduce respiratory resistance, prolong the cycle of changing filter element not increasing the filter element planar dimension, not changing under the prerequisite of filter element material and increase filter area and dust containing capacity greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a vertical section of the present utility model structural map.
Fig. 2 is a top view of the present utility model.
Fig. 3 is the vertical section structural map that the utility model is folding and compression is preceding.
Fig. 4 is the blanking shape figure of first embodiment of the utility model.
Fig. 5 is the blanking shape figure of second embodiment of the utility model.
The specific embodiment
In Fig. 3, each ladder place is the turning point that folds, and the height of ladder is exactly the height of filter element.
In the embodiment shown in fig. 4, utilize the plasticity of material,, be folded into the shape of Fig. 1 then the shape that illustrated circular filtering material stretches earlier, pressing and fixiform becomes Fig. 3.
In another embodiment shown in Figure 5, but utilize the viscosity of material, with illustrated fan-shaped filtering material earlier bonding, pressing and fixiform become the shape of Fig. 3, be folded into the shape of Fig. 1 then.
Claims (3)
1. anti-dust respirator filter element, by material manufacturing with a large amount of micro gaps or micropore, it is characterized in that: the surface has limited cylindrical of the height of some annular ripples, be the taper shape that several ladders arranged of surface area much larger than the filter element projected area after the expansion, cone bottom diameter equals the diameter projected of filter element.
2. anti-dust respirator filter element according to claim 1 is characterized in that by circular filtering material manufacturing.
3. anti-dust respirator filter element according to claim 1 is characterized in that by fan-shaped filtering material manufacturing.
