Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an antibacterial and antiviral composite air filter. Background Technology

[0002] Air filters are classified into four types: coarse, medium, sub-high efficiency, and high efficiency. Different numbers of air filters are installed at the air inlet according to the air volume to achieve the purpose of air purification. Air filters are widely used.

[0003] Most current air filters have a continuous folded structure design, which aims to increase the contact area with air and enhance the filtering, antibacterial, and antiviral effects. However, after prolonged use, the filters tend to accumulate a lot of dust, and because of their folded shape, there are many and deep gaps, making cleaning quite troublesome and requiring improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antibacterial and antiviral composite air filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An antibacterial and antiviral composite air filter includes a filter screen comprising an inner filter layer, a first outer antibacterial layer, and a second outer antibacterial layer. The inner filter layer is fixed between the first and second outer antibacterial layers. The filter screen is composed of the inner filter layer, the first outer antibacterial layer, and the second outer antibacterial layer. The first and second outer antibacterial layers are made of materials that meet national standards. The inner filter layer is made of non-woven filter cotton, which can effectively remove irritating and toxic gases in the air, such as formaldehyde, and play an antibacterial and antiviral role. The filter screen has symmetrical first and second perforations. A positioning sleeve is fixed in the first perforation. A plurality of threaded sleeves are equipped with the same bidirectional screw that is adapted to them. A positioning component is installed in the second perforation.

[0006] As a further embodiment of this utility model, the positioning component includes a guide rod passing through the positioning sleeve, and connecting rods are fixed to the outer walls of the two positioning sleeves on both sides, and the connecting rods are fixed to the corresponding threaded sleeves.

[0007] As a further embodiment of this utility model, the outer walls of the threaded sleeve and the positioning sleeve on which the connecting rod is installed are both fixed with threaded sleeves.

[0008] As a further embodiment of this utility model, both ends of the guide rod are provided with first screw holes, and one end of the bidirectional lead screw is provided with a second screw hole. The system is equipped with a threaded sleeve, first screw hole, and second screw hole, etc., which can be used to install a frame. The frame is fixed to the threaded sleeve, first screw hole, and second screw hole by bolts, and can be detached and fixed.

[0009] As a further embodiment of this utility model, the filter screen is pressed with creases, and the creases are evenly spaced.

[0010] As a further embodiment of this utility model, the inner filter layer is non-woven filter cotton.

[0011] The beneficial effects of this utility model are as follows: This utility model features a filter screen composed of an inner filter layer, a first outer antibacterial layer, and a second outer antibacterial layer. The first and second outer antibacterial layers are made of materials that meet national standards, while the inner filter layer is made of non-woven fabric filter cotton. This effectively removes irritating and toxic gases from the air, such as formaldehyde, thus providing antibacterial and antiviral effects.

[0012] This utility model features a filter screen equipped with threaded sleeves, positioning sleeves, a bidirectional lead screw, and positioning components. The filter screen has equidistant creases. One end of the bidirectional lead screw can be connected to a handle, allowing the lead screw to rotate. Under the action of the connecting rod and guide rod, the two symmetrical threaded sleeves are brought closer together, achieving the folding effect on the filter screen. This effectively solves the problems mentioned in the background art, enabling adjustment of the filter screen's opening and closing, changing the filtration area. When the filter screen is straightened, it aids in dust removal; when folded up, it increases the filtration surface area. Attached Figure Description
