[0002] Air conditioners, also known as air conditioners, process the temperature, humidity, purity, and air flow rate of the air. Air conditioner filters can absorb slightly larger solid particles in the air to ensure the cleanliness of the air. When using existing external air conditioner filters, the filter size usually matches the size of the installation frame. When the size of the installation frame is large, a filter of appropriate size needs to be designed. Large filters are more inconvenient to transport and are easily twisted and damaged when turned, resulting in poor performance. After long-term use of the air conditioner, a large amount of impurities will adhere to the filter. The filter is fixed to the frame with bolts, which makes disassembly more cumbersome and the disassembly and replacement efficiency is low.

[0003] In the existing technology, such as the "An external air-conditioning filter" with the Chinese authorization announcement number CN220852377U, it includes a mounting frame body, three fixed frames, and a filter body. The three fixed frames respectively surround the outer ring of the filter body and are fixedly connected to the filter body. A mounting groove is provided inside the mounting frame body, and the filter body is installed in the mounting frame body through the fixed frame. The front end of the mounting frame body is fixedly connected with fixed blocks at the four corners and the center. The side close to the center point of the mounting frame body is movably connected with a stopper through a thrust spring, and a connecting rod is movably connected at the center of both sides of the stopper, and the end of the connecting rod is fixedly connected to the fixed block. The external air-conditioning filter described in the utility model avoids the filter body being too large and insufficient in strength, resulting in one end drooping and twisting and damage, thereby improving transportation safety, facilitating the installation efficiency of the filter body, and facilitating disassembly and cleaning.

[0023] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a PET high-density filter screen with a replaceable filter element provided by the present invention; Figure 2 for Figure 1 An exploded view of a high-density PET filter with a replaceable filter element; Figure 3 for Figure 1 A front view of a positioning sleeve in a PET high-density filter screen with a replaceable filter element is shown; Figure 4 for Figure 1 A front view of the mounting mechanism for a PET high-density filter with a replaceable filter element. The PET high-density filter with a replaceable filter element comprises a positioning sleeve 1, a high-density mesh 2 fixedly sleeved inside the positioning sleeve 1, an auxiliary layer 3 fixedly connected to the top of the high-density mesh 2, an antiviral coating 4 provided on the top of the auxiliary layer 3, a reinforcement rod 5 fixedly sleeved inside the positioning sleeve 1, a buckle 6 fixedly connected to the side of the positioning sleeve 1, a fixing ring 7 fixedly sleeved on the top of the fixing ring 7, a reinforcement pad 8 fixedly sleeved on the top of the fixing ring 7, and a mounting mechanism 9 provided on the bottom of the positioning sleeve 1.

[0025] There are two antiviral coatings 4, and the two antiviral coatings 4 are symmetrically distributed with the high-density mesh 2 as the symmetry axis; by setting the antiviral coating 4, when dust accumulates on the surface of the filter when it is in use, the antiviral coating 4 can induce destruction of the viruses inside the dust, so that the viruses on the surface of the filter can be stably killed, thereby achieving the antiviral and antifungal effects of the filter, avoiding the problem of greatly reduced air quality when viruses and molds are accompanied by dust, thereby improving the filtering and cleaning effect when the filter is in use.

[0026] The material of the high-density net 2 is polyester material, and the high-density net 2 is compatible with the positioning sleeve 1; by setting the high-density net 2, when dust filtering is performed, the high-density net 2 with a larger thickness value can block most of the dust, so that the dust can be blocked and stuck inside the high-density net 2, thereby improving the filtering effect of the filter net.

[0027] The auxiliary layer 3 is made of natural fiber material, and the auxiliary layer 3 and the high-density net 2 are parallel to each other; by setting the auxiliary layer 3, when the filter net is used, the auxiliary layer 3 can greatly improve the toughness of the filter net, that is, improve the firmness of the filter net, thereby avoiding the problem of the filter net being corroded during long-term use, resulting in a greatly reduced service life, thereby improving the service life of the filter net.

[0028] There are two reinforcement rods 5, and the two reinforcement rods 5 are perpendicular to each other. By setting the reinforcement rods 5, when the filter is in use, the reinforcement rods 5 can support and limit the position of the filter, thereby avoiding the problem of the filter bending when the air flow speed inside the filter is fast, thereby improving the stability of the filter shape.

[0029] The fixing ring 7 is located directly above the positioning sleeve 1, and the size of the fixing ring 7 is the same as that of the positioning sleeve 1; by setting the fixing ring 7, when the high-density net 2 needs to be installed and fixed, the high-density net 2 is sleeved on the inside of the positioning sleeve 1, and at this time, the fixing ring 7 is sleeved on the inside of the buckle 6, so that the fixing ring 7 can squeeze and fix the high-density net 2 on the inside of the positioning sleeve 1, thereby achieving the fixing effect of the high-density net 2, thereby bringing convenience to the installation and disassembly of the filter net, that is, it brings convenience to the replacement of the filter net.

[0030] The material of the reinforcement pad 8 is rubber material, and the number of the reinforcement pads 8 is four; by setting the reinforcement pad 8, when the high-density net 2 is squeezed and fixed, the reinforcement pad 8 can fill the gap between the buckle 6 and the fixing ring 7, thereby avoiding the problem that the gap between the buckle 6 and the fixing ring 7 is large, causing the high-density net 2 to shake, thereby improving the stability of the high-density net 2 after fixation.

[0031] The mounting mechanism 9 includes a positioning ring 91, which is movably sleeved on the outside of the positioning sleeve 1, and a bolt 92 is threadedly sleeved on the front of the positioning ring 91; by setting the mounting mechanism 9, when the filter is installed and fixed, the positioning sleeve 1 is sleeved on the inside of the positioning ring 91, and the bolt 92 is rotated at this time so that the bolt 92 can squeeze and fix the positioning sleeve 1 on the temporal part of the positioning ring 91, thereby achieving the installation and fixing effect of the high-density net 2, which brings convenience to the installation and fixation of the filter.

[0032] The working principle of the PET high-density filter with replaceable filter element provided by the utility model is as follows:

[0033] Step 1: First, when dust accumulates on the surface of the filter when it is in use, the antiviral coating 4 can induce and destroy the viruses inside the dust, so that the viruses on the surface of the filter can be stably killed, thereby achieving the antiviral and antifungal effects of the filter, thereby avoiding the problem of viruses and molds accompanying dust drifting and causing a significant decrease in air quality, thereby improving the filtering and cleaning effect of the filter when it is in use; when filtering dust, the high-density mesh 2 with a larger thickness can block most of the dust, so that the dust can be blocked and stuck inside the high-density mesh 2, thereby improving the filtering effect of the filter; when the filter is in use, the auxiliary layer 3 can greatly improve the toughness of the filter, that is, improve the firmness of the filter, thereby avoiding the problem of the filter being corroded and greatly reducing its service life when used for a long time, thereby improving the service life of the filter; when the filter is in use, the reinforcement rod 5 can support and limit the position of the filter, thereby avoiding the problem of the filter bending when the air flow speed inside the filter is fast, thereby improving the stability of the filter shape;

[0034] When the filter screen is to be installed and fixed, the positioning sleeve 1 is sleeved on the inside of the positioning sleeve 1. At this time, the fixing ring 7 is sleeved on the inside of the buckle 6, so that the fixing ring 7 can squeeze and fix the high-density mesh 2 inside the positioning sleeve 1, thereby achieving the fixing effect of the high-density mesh 2, which brings convenience to the installation and disassembly of the filter screen, that is, it brings convenience to the replacement of the filter screen. When the high-density mesh 2 is squeezed and fixed, the reinforcing pad 8 can fill the gap between the buckle 6 and the fixing ring 7, thereby avoiding the problem of the high-density mesh 2 shaking due to the large gap between the buckle 6 and the fixing ring 7, thereby improving the stability of the high-density mesh 2 after being fixed. When the filter screen is to be installed and fixed, the positioning sleeve 1 is sleeved on the inside of the positioning ring 91. At this time, the bolt 92 is rotated so that the bolt 92 can squeeze and fix the positioning sleeve 1 on the temporal part of the positioning ring 91, thereby achieving the installation and fixing effect of the high-density mesh 2, that is, it brings convenience to the installation and fixing of the filter screen.

[0035] Compared with the related art, the PET high-density filter screen with a replaceable filter element provided by the utility model has the following beneficial effects:

[0036] By providing the antiviral coating 4, when dust accumulates on the surface of the filter when it is in use, the antiviral coating 4 can induce destruction of the viruses inside the dust, so that the viruses on the surface of the filter can be stably killed, thereby achieving the antiviral and antifungal effects of the filter, avoiding the problem of greatly reduced air quality when viruses and mold are accompanied by dust, thereby improving the filtering and cleaning effect of the filter when it is in use.
