The air purifier comprises a filter screen 1, an upper mounting plate 2, a lower mounting plate 3, a side plate 4, a sealed cavity 5, a filter screen 51, an upper edge 52 of the filter screen, a lower edge 6 of the filter screen, an inner cavity 7 of the filter screen, an air inlet 8, an air outlet 9, a concave-convex area 10, a positioning strut 11, a folded angle 12, a transverse filter screen 13 and an elastic layer.
Detailed Description
The utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1-4, the dust remover with improved filter screen comprises a machine shell, the machine shell comprises an upper mounting plate 1, a lower mounting plate 2 and a side plate 3, the upper mounting plate, the lower mounting plate and the side plate form a sealed structure, the inside is a sealed cavity 4, a vertical filter screen 5 is arranged in the cavity, the cross section of the filter screen is annular, the upper edge 51 of the filter screen is in sealing contact with the upper mounting plate, the lower edge 52 of the filter screen is in sealing contact with the lower mounting plate, the inside of the filter screen is a filter screen inner cavity 6, an air inlet 7 is arranged on the side plate, an air outlet 8 is arranged at the lower mounting plate, and the air outlet corresponds to the filter screen inner cavity 6, and the dust remover is characterized in that: the cross section of the filter screen is of an annular structure with a plurality of concave-convex areas 9.
The technical scheme of the utility model is realized as follows: when the air purifier is used, dirty air is introduced into the air inlet, enters the inner cavity of the filter screen after passing through the filter screen, is filtered to become clean air, and then is discharged from the air outlet; because the cross-section of filter screen is the annular structure who has many concave-convex areas, the area of contact of the surface of filter screen and air is bigger like this, has the advantage that the filtered air is more, filterable efficiency is higher of unit interval.
As shown in fig. 6, further, the concave-convex area of the filter screen on the side close to the air inlet is denser than that on the side far from the air inlet.
Because most of the dirty air enters from the air inlet nearby, the filter screen is more fully utilized.
As shown in fig. 5-7, furthermore, a plurality of positioning pillars 10 are installed between the upper mounting plate and the lower mounting plate, and the positioning pillars are arranged at the folding angles 11 of the concave-convex areas of the filter screen.
The positioning support column is arranged to play a role in supporting the filter screen, so that the filter screen can still keep shape after being used for a long time.
As shown in fig. 6, further, a transverse screen 12, which is a second screen, is mounted between the lower edge of the screen and the lower mounting plate, and is sealingly mounted on the lower mounting plate, and covers the air outlet, the fineness of the second screen being smaller.
Thus, the filtering effect is better after the secondary filtering.
Further, the positioning pillar 10 has an elastic layer 13 on its outer periphery.
Therefore, the abrasion of the positioning support column to the filter screen is reduced, and the function of protecting the filter screen is achieved.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
