Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In one aspect of the utility model, an air purifying composite screen is provided. Referring to fig. 1 and 2, the air cleaning composite screen 1000 includes a screen base 100 and catalyst particles 200, wherein the catalyst particles 200 are attached to the screen base 100. Screen matrix 100 is serrated, and screen matrix 100 has peaks 110 and valleys 120. From this, through on adhering to the surface of the filter screen base member of cockscomb structure with catalyst particle, can effectively increase the area of contact of air and catalyst particle, the circulation of air resistance is less moreover to be favorable to improving the air purification function of air purification composite filter screen.
It should be noted that fig. 1 to 2 only illustrate the structure of the composite screen, and do not show the specific structure of the catalyst particles, and referring to fig. 3 (fig. 3 is an enlarged view of a region a in fig. 2), the catalyst particles 200 are attached to the screen base 100.
According to some embodiments of the present invention, referring to fig. 1 and 2, the distance d between two adjacent peaks 110 is 2.2mm to 12.5 mm. It should be noted here that the peaks and valleys of the saw-toothed structure are relative, and in the vertical direction, the tip portion of one side of the saw-toothed structure is defined as a peak, and the tip portion of the other side is defined as a valley, so that in the present invention, the distance between two adjacent peaks or the distance between two adjacent valleys is 2.2mm to 12.5 mm. According to some embodiments of the utility model, the spacing between two adjacent crests may be 2.2mm, 2.5mm, 2.8mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, 10.0mm, 10.5mm, 11.0mm, 11.5mm, 12.0mm, 12.5 mm. Therefore, the distance between two adjacent tooth peaks of the filter screen base body (or the distance between two adjacent tooth valleys) is set in the range, so that the contact area of air and catalyst particles can be further increased, the air circulation resistance is small, and the air purification function of the air purification composite filter screen is further improved. If the distance between two adjacent tooth peaks is too small, for example, less than 2.2mm, the tooth peaks and the tooth valleys of the filter screen are mutually extruded, and the resistance is large when air passes through, so that the air purification efficiency of the air purification composite filter screen is reduced; if the distance between two adjacent tooth peaks is too large, for example, greater than 12.5mm, the effective cross-sectional area through which air passes or the area of the expanded filter screen is too small, the contact area between the air and the catalyst particles is relatively small, and the resistance is also relatively large, so that the air purification efficiency of the air purification composite filter screen is seriously reduced.
According to an embodiment of the present invention, referring to fig. 1, the vertical spacing h between the crests 110 and valleys 120 of the mesh base 100 is 8mm to 60mm, and may be, for example, 8mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60 mm. Therefore, the vertical distance between the tooth peaks and the tooth valleys is set in the range, the contact area between the air and the filter screen base body is large, namely, the air and the catalyst particles have large contact area, and the air has proper flow velocity and resistance when passing through the filter screen base body, so that the air purification efficiency of the air purification composite filter screen is improved. If the vertical distance between the tooth peaks and the tooth valleys is too small, for example, less than 8mm, on the premise that the air volume is the same, when the air passes through the filter screen, the contact area between the air and the filter screen is smaller, the air passes through the surface of the filter screen with smaller area, the wind resistance is increased, the air purification efficiency of the filter screen is reduced, meanwhile, the time for the air to pass through the filter screen is also shorter, the catalyst cannot fully react with harmful substances such as formaldehyde in the air, and the purification efficiency of the filter screen is further reduced; if the vertical distance between the teeth peaks and the teeth valleys is too large, for example, greater than 60mm, on the premise of maintaining the same fold density, the folds (the structure between two adjacent teeth peaks or the structure between two adjacent teeth valleys) of the filter screen are very tightly overlapped with each other, and the resistance when air passes through the filter screen is very large, resulting in a very small air speed and a very small air volume, thereby reducing the purification efficiency.
In the same filter screen base body 100, the vertical distances h between different teeth 110 and different valleys 120 may be equal (as shown in fig. 1), and the vertical distances h between different teeth 110 and different valleys 120 may also be different, but the vertical distance h between any one tooth 110 and any one valley 120 is between 8mm and 60mm, so as to better ensure a larger contact area between the air and the catalyst particles 200.
According to an embodiment of the utility model, the filter screen base is folded to form a zigzag structure, and the crease density n is 80-450 folds/m, such as 80 folds/m, 100 folds/m, 120 folds/m, 140 folds/m, 150 folds/m, 180 folds/m, 200 folds/m, 230 folds/m, 250 folds/m, 280 folds/m, 300 folds/m, 320 folds/m, 350 folds/m, 400 folds/m, 420 folds/m, 440 folds/m, 450 folds/m. Here, the term "fold" refers to a structure between two adjacent peaks or a structure between two adjacent valleys, and referring to fig. 1 to 2, when the length of the screen base 100 is L, L is n × d. Therefore, the crease density is set to be 80-450 folds/meter, so that a proper distance is formed between adjacent tooth peaks or adjacent tooth valleys, and the purification efficiency of the air purification composite filter screen is improved; if the crease density is less than 80 folds/meter, the interval between adjacent tooth peaks (or tooth valleys) is relatively large, so that the effective sectional area through which air passes or the expanded area of the filter screen is too small, the contact area between the air and catalyst particles is relatively small, the resistance is relatively large, and the air purification efficiency of the air purification composite filter screen is seriously reduced; if the crease density is greater than 450 folds/meter, the interval between adjacent tooth peaks (or tooth valleys) is relatively small, so that the tooth peaks and the tooth valleys of the filter screen are mutually extruded, the resistance when air passes through the filter screen is relatively large, and the air purification efficiency of the air purification composite filter screen is reduced.
According to an embodiment of the present invention, the material of the filter screen base includes plastic or metal. According to some embodiments of the present invention, the material of the filter mesh substrate may be PP (polypropylene) fibers, PET (polyethylene terephthalate) fibers, PTFE (polytetrafluoroethylene) fibers, metal mesh or metal fiber mesh. From this, the filter screen base member has the hole structure, is favorable to the flow of air, and then is favorable to improving the purification efficiency of filter screen.
According to some embodiments of the present invention, the material of the filter screen base is stainless steel or aluminum alloy, thereby further improving the purification efficiency of the filter screen.
According to an embodiment of the utility model, the catalyst particles are manganese dioxide, titanium dioxide, silver or platinum. Therefore, the catalyst particles have better formaldehyde catalytic oxidation performance. According to some specific embodiments of the utility model, the catalyst particles are manganese dioxide, so that the formaldehyde catalytic oxidation performance of the catalyst particles is better, and the catalyst particles have the advantages of wide sources, low price and the like, thereby being beneficial to reducing the cost of the composite filter screen, and being environment-friendly and not easy to generate secondary pollution in the using process.
According to some embodiments of the present invention, referring to fig. 4, the mesh base is a net structure composed of a plurality of wires 130 extending in different directions (as will be understood by those skilled in the art, the net structure includes the wires 130 and the mesh holes 140 formed by crossing the wires 130), and the catalyst particles 200 are attached to the wires 130. Therefore, catalyst particles are attached to the filter screen base body on the net structure, the contact area of the catalyst and air is increased, and the purification efficiency of the composite filter screen is improved. It should be noted here that the catalyst particles 200 adhering to the mesh 130 includes a portion of the catalyst particles 200 adhering to the inside of the mesh 140, that is, a portion of the catalyst particles 200 also adhering to the mesh 130 in a direction toward the mesh 140. In addition, in the interlaced regions of the mesh 130 (i.e., the regions where different meshes intersect), a relatively large number of catalyst particles 200 are attached.
According to an embodiment of the utility model, the composite screen further comprises a binder by which the catalyst particles are attached to the screen matrix. The catalyst particles are bonded on the filter screen substrate through the adhesive, so that the air purification composite filter screen is prevented from falling off, namely the catalyst particles are prevented from falling off.
The method for forming the catalyst particles in the present invention is not particularly limited. According to some embodiments of the utility model, the catalyst particles may be physically bonded or chemically bonded to the screen substrate by a binder. Specifically, according to some embodiments of the present invention, a layer of adhesive may be coated on the filter mesh substrate, and then the catalyst particles are uniformly adhered to the filter mesh substrate, and then the catalyst particles are adhered to the filter mesh substrate by curing. According to other embodiments of the present invention, the catalyst raw material may be uniformly dispersed in the binder solution, and then the mixture may be uniformly coated on the filter mesh substrate, and the catalyst particles may be firmly supported on the filter mesh substrate through the curing process. The kind of the binder is not particularly limited as long as the catalyst can be firmly supported on the filter mesh substrate, and those skilled in the art can select the binder according to actual needs. According to some embodiments of the present invention, the binder may be an acrylic binder or a polyurethane binder, etc., thereby facilitating the catalyst to be firmly supported on the mesh substrate. The temperature of the curing treatment is also not particularly limited and may be selected by those skilled in the art according to the actual circumstances. According to some embodiments of the present invention, the curing temperature is 80 ℃ to 150 ℃, so that the adhesive can be cured in a shorter time, which is beneficial to shortening the production time and further reducing the cost.
According to an embodiment of the utility model, the composite screen is in the shape of a flat plate or a cylinder. The flat plate-shaped or cylindrical shape means that the filter screen base body of the composite filter screen is folded to form a saw-toothed structure, and then the saw-toothed structure forms a flat plate-shaped or cylindrical shape, wherein the flat plate-shaped structure is formed by laying the saw-toothed structure flat, and the cylindrical shape is formed by surrounding the saw-toothed structure to form a ring shape. Thereby, the installation of the composite filter screen is facilitated.
According to an embodiment of the present invention, referring to fig. 5, the air purification composite filter screen 1000 may further include a HEPA filter screen 300, and the HEPA filter screen 300 is zigzag and stacked on the filter screen base 100. From this, the HEPA filter screen can keep unanimous shape with the filter screen base member, is favorable to the installation of composite filter screen to composite filter screen can carry out effective filtration to the particle (size is at 0.3 micron and above) in the air when getting rid of formaldehyde, further improves composite filter screen's performance.

Therefore, the electric appliance has all the characteristics and advantages of the air purification composite filter screen, and the description is omitted. In general, the electric appliance has better air purification performance.
According to the embodiment of the utility model, the specific type of the electric appliance has no special requirement, and a person skilled in the art can flexibly select the electric appliance according to the actual situation, for example, the electric appliance can be an air purifier, an air conditioner and other electric appliances.
