In an embodiment of the present invention, as shown in fig. 3, the formaldehyde filter 100 includes:
a substrate 10, the substrate 10 having a plurality of vent holes 11 extending in a thickness direction of the substrate 10; and
and the catalytic layer (not shown) is arranged on the surface of the pore wall of the vent hole 11.
Optionally, a plurality of the vent holes 11 are distributed on the whole surface of the substrate 10, so that the whole formaldehyde filter 100 is substantially in a honeycomb shape.
Specifically, the preparation material of the catalytic layer comprises a catalyst, and the catalyst comprises, but is not limited to, manganese dioxide, titanium dioxide, silver oxide and the like; and the preparation material of the catalyst comprises at least one of manganese dioxide, titanium dioxide, silver oxide and the like.
The catalytic layer can be provided as a coating or plating layer so that the catalytic layer is firmly attached to the surface of the hole wall of the vent hole 11, thereby simplifying the manufacturing process of the formaldehyde filter screen 100 and preventing the catalytic layer from falling off. Of course, the catalytic layer may be provided on the surface of the pore wall of the vent hole 11 by other means, such as adhesion with an adhesive.
Specifically, when air flows through the air vent 11, the catalyst of the catalyst layer catalyzes formaldehyde in the air to perform a (complex) chemical reaction, so as to decompose the formaldehyde into carbon dioxide and water, thereby achieving the purpose of removing the formaldehyde in the air. In addition, in the decomposition process of formaldehyde, the catalyst layer only plays a role of catalysis and cannot be lost, so that the formaldehyde filter screen 100 has a long service life.
Further, as shown in fig. 3 to 5, the cross-sectional shape of the vent hole 11 is triangular.
It can be understood that the triangular structure has strong stability. Based on this, the utility model discloses formaldehyde filter screen 100 sets up to triangle-shaped through the cross sectional shape that makes air vent 11, can make connection relatively stable between each lateral wall of air vent 11, firm, indestructible to can strengthen formaldehyde filter screen 100's overall structure intensity, reduce the risk that formaldehyde filter screen 100 damaged, with the life who improves formaldehyde filter screen 100.

That is to say, the utility model discloses formaldehyde filter screen 100 overall structure intensity is high, and is not fragile, and long service life.
Of course, in other embodiments, the cross-sectional shape of the vent hole 11 may be other shapes, such as trapezoid, rectangle, or the like.
Further, the sizes of the plurality of ventilation holes 11 may not be all the same, that is, the sizes of at least two ventilation holes 11 may be different, so as to satisfy the overall structural strength, the filtering wind resistance, the filtering area, and the like of the formaldehyde filter 100, which will be described in detail below.
In another embodiment of the present invention, as shown in fig. 4, the ventilation holes 11 include a plurality of first ventilation holes 111 and a plurality of second ventilation holes 112, and the size of the first ventilation holes 111 is larger than the size of the second ventilation holes 112.
So, through forming the great first ventilation hole of size, can reduce the windage, guarantee formaldehyde filter screen 100's air volume. Meanwhile, by forming the second ventilation holes with smaller sizes, the overall structural strength of the formaldehyde filter screen 100 can be increased, and the filtering area of the formaldehyde filter screen 100 can be increased, so that the filtering efficiency is improved.
In this embodiment, as shown in fig. 4, the second vent hole 112 is disposed in the first vent hole 111, and another second vent hole 112 is formed between a side wall of the second vent hole 112 and a wall of the first vent hole 111. Therefore, the design difficulty of the first vent hole 111 and the second vent hole 112 can be simplified, and the manufacturing difficulty of the formaldehyde filter screen 100 can be reduced.
In this embodiment, specifically, the second vent hole 112 is provided in the first vent hole 111, and a plurality of second vent holes 112 may be formed in the first vent hole 111. Alternatively, as shown in fig. 5, three sidewalls of the second vent hole 112 and the wall of the first vent hole 111 form another three second vent holes 112, that is, four second vent holes 112 are formed in one first vent hole 111.
For convenience of description, it is possible to define: the second vent holes 112 are provided in the first vent holes 111 to form a plurality of second vent holes 112 in the first vent holes 111, and the plurality of second vent holes 112 formed in the one first vent hole 111 form the vent cluster 1. The row of the vent holes 11 with the vent hole cluster 1 is the close row 2, and the row of the vent holes 11 with only the first vent holes 111 (i.e. without the vent hole cluster 1) is the open row 3.
In this embodiment, alternatively, for the close row 2, the vent clusters 1 may be alternately arranged with one vent 11 or a plurality of vents 11 in sequence. Therefore, the wind resistance of the close-packed 2 can be reduced, so that the wind resistance of the formaldehyde filter screen 100 at the close-packed 2 can be reduced, and the ventilation uniformity of the formaldehyde filter screen 100 can be improved.
In this embodiment, specifically, as shown in fig. 5, the close rows 2 may be alternately arranged with one open row 3 or a plurality of open rows 3. Therefore, the ventilation performance of the formaldehyde filter screen 100 can be ensured, and the ventilation quantity of the formaldehyde filter screen is ensured; but also can increase the filtering area to improve the filtering efficiency. In addition, the ventilation uniformity of the formaldehyde filter screen 100 can be improved conveniently.
In another embodiment of the present invention, as shown in fig. 5, the ventilation holes 11 include a plurality of first ventilation holes 111 and a plurality of second ventilation holes 112, and the size of the first ventilation holes 111 is larger than that of the second ventilation holes 112; the plurality of second ventilation holes 112 are disposed in a dispersed manner between the plurality of first ventilation holes 111. Therefore, by arranging the first vent hole and the second vent hole which are different in size, the ventilation performance of the formaldehyde filter screen 100 can be ensured, and the ventilation quantity of the formaldehyde filter screen is ensured; but also can increase the filtering area to improve the filtering efficiency. In addition, the second ventilation holes 112 are dispersedly arranged among the first ventilation holes 111, so that the ventilation uniformity of the formaldehyde filter screen 100 can be improved.
In this embodiment, optionally, the plurality of first ventilation holes 111 and the plurality of second ventilation holes 112 are regularly distributed.
In some embodiments of the formaldehyde filter 100, as shown in fig. 6, the depth direction of the vent hole 11 is inclined to the thickness direction of the substrate 10. Thus, the area of the wall of the vent hole 11 can be increased, so that the filtering area can be increased, the filtering efficiency (formaldehyde removing efficiency) can be improved, and the purifying effect can be improved.
It should be noted that the technical solutions between the above embodiments of the present invention can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Further, the manufacturing material of the substrate 10 includes a paper material. In this embodiment, the substrate 10 may be made of a paper material, and the surface of the paper material is rough, so that the adhesion area can be increased, the adhesion force to the catalytic layer can be increased, and the risk of the catalytic layer falling off can be reduced. In addition, because the paper material is cheaper, the production cost of the formaldehyde filter screen 100 can be effectively reduced.
Further, the mesh number of the vent holes 11 is greater than or equal to 50 and less than or equal to 120.
It can be understood that the mesh number represents the distribution density of the vent holes 11, and if the mesh number of the vent holes 11 is smaller, the distribution of the vent holes 11 on the formaldehyde filter screen 100 is thinner, and the filter area of the formaldehyde filter screen 100 is smaller; conversely, if the mesh number of the vent holes 11 is larger, the more densely the vent holes 11 are distributed in the formaldehyde filter 100, the larger the filter area of the formaldehyde filter 100 is, but the larger the wind resistance of the formaldehyde filter 100 is.
It can be understood that if the mesh number of the vent holes 11 is too small, the filtering area of the formaldehyde filter 100 becomes too small, and the filtering efficiency and the purification effect are greatly reduced. If the mesh number of the vent holes 11 is too large, the wind resistance of the formaldehyde filter 100 becomes too large, and the ventilation amount of the formaldehyde filter 100 is greatly reduced. The mesh number of the vent holes 11 is set to be 50 or more and 120 or less. More specifically, the mesh number of the vent holes 11 is set to 80 or more and 100 or less. Therefore, the filtering area of the formaldehyde filter screen 100 can be ensured, and the wind resistance of the formaldehyde filter screen 100 can be reduced.
Further, the thickness of the substrate 10 is greater than or equal to 5 mm and less than or equal to 30 mm.
It can be understood that, if the thickness of the substrate 10 is thinner, the time for the air to flow in the vent hole 11 is shorter, and the filtering area of the formaldehyde filtering net 100 is smaller; conversely, if the thickness of the substrate 10 is thicker, the longer the air flows in the vent holes 11, the larger the filter area of the formaldehyde filter 100 becomes, but the larger the wind resistance of the formaldehyde filter 100 becomes.
It can be understood that if the thickness of the substrate 10 is too thin, the filtering area of the formaldehyde filter 100 is too small, and the filtering efficiency and the purification effect are greatly reduced. If the thickness of the base plate 10 is too thick, the wind resistance of the formaldehyde filter 100 becomes too large, and the ventilation amount of the formaldehyde filter 100 is greatly reduced. The thickness of the substrate 10 is set to be greater than or equal to 5 mm and less than or equal to 30 mm. More specifically, 10 mm or more and 20 mm or less. Therefore, the filtering area of the formaldehyde filter screen 100 can be ensured, and the wind resistance of the formaldehyde filter screen 100 can be reduced.
