Technical Field

[0001] The utility model belongs to the technical field of filtering, and in particular relates to an environmentally friendly composite filtering structure for an air purifier. Background Art

[0002] The composite filter structure is usually composed of multiple filter layers with different functions. This design allows the air to be filtered step by step when passing through the purifier, thereby achieving effective removal of particulate matter of different particle sizes, gaseous pollutants and microorganisms. In the prior art, multiple filter plates are usually arranged inside the shell to filter the air. However, in this method, the filter is fixed inside the shell and is not convenient to disassemble. The filter that cannot be easily disassembled cannot be routinely cleaned on the surface. The dust accumulated on the surface of the filter will gradually affect the air circulation efficiency, resulting in a decrease in purification efficiency.

[0003] For example, the utility model with announcement number CN206739479U discloses an environmentally friendly composite filter structure for an air purifier. In the technical solution of this patent, a plurality of filter devices are arranged inside the shell, and filter nets are arranged inside the filter devices to filter the air. However, in this method, the filter nets are fixed inside the filter device and are not convenient to disassemble. The fixed and non-detachable filter nets make it impossible for users to perform conventional surface cleaning, such as vacuuming or washing with water. The dust accumulated on the surface of the filter net will gradually hinder the air circulation and reduce the purification efficiency. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies of the prior art and provides an environmentally friendly composite filter structure for an air purifier, which can not only clean the particulate matter accumulated on the pre-filter plate through the cleaning component, but also facilitate the disassembly and replacement of the composite filter plate, thereby helping to maintain the optimal performance state of the filter and extend the service life of the air purifier.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an environmentally friendly composite filtering structure for an air purifier, including a box body, an air inlet is arranged on the left side of the box body, an air outlet is arranged on the outside, a pre-filter plate is arranged on the left side of the box body, a cleaning component is arranged on the left side of the pre-filter plate, activated carbon is arranged on the right side of the pre-filter plate, a box door is arranged at the upper end of the box body, a handle is arranged on the box door, a groove is arranged at the inner right end of the box body, a composite filter net is detachably arranged inside the groove, and a fixing component for fixing the composite filter net is arranged on the right side of the groove.

[0006] As a further improvement of the utility model, the fixing assembly includes a fixing frame arranged on the right side of the groove, a sliding column is slidingly arranged inside the fixing frame, a limiting plate is arranged at the left end of the sliding column, a spring is arranged between the right side wall of the limiting plate and the inner side wall of the fixing frame, a fixing plate is arranged at one end of the sliding column located on the outside of the fixing frame, and a pin is arranged at the left end of the limiting plate.

[0010] As a further improvement of the utility model, universal wheels are arranged at the lower end of the box body, and brake pads are arranged on the universal wheels.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Firstly, by setting up a fixing component, when the composite filter needs to be disassembled, the fixing plate is pulled to the right so that the sliding column moves to the right. The movement of the sliding column can make the limit plate compression spring move to the right, thereby making the pin disengage from the slot of the composite filter so that the composite filter plate can be taken out of the groove. After replacing the composite filter plate, when fixing it, loosening the fixing plate can make the sliding column move to the left so that the limit plate moves to the left under the elastic force of the spring, so that the limit plate drives the pin to move to the left and insert into the slot of the composite filter plate to fix the composite filter plate. The easy disassembly design means that users can easily take out the composite filter plate for regular cleaning, which helps to maintain the optimal performance of the filter and extend the service life of the air purifier.

[0013] Secondly, by setting up a pre-filter plate, larger particles in the air can be captured, reducing the burden on subsequent filter layers and ensuring the stable operation of the entire purification system.

[0014] Thirdly, by setting a cleaning component, starting the telescopic push rod can make the slide plate drive the brush plate to move up and down, so as to remove the particles on the pre-filter plate.

[0015] Fourthly, by providing the through holes, the cleaned particles can fall into the interior of the collection box to avoid polluting the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 , 3 As shown, the fixing assembly includes a fixing frame 201 arranged on the right side of the groove 108, a sliding column 202 is slidably arranged inside the fixing frame 201, a limiting plate 203 is arranged at the left end of the sliding column 202, a spring 204 is arranged between the right side wall of the limiting plate 203 and the inner side wall of the fixing frame 201, a fixing plate 205 is arranged at one end of the sliding column 202 located outside the fixing frame 201, and a pin 206 is arranged at the left end of the limiting plate 203. By setting the fixing assembly, when it is necessary to disassemble the composite filter screen 109, the fixing plate 205 is pulled to the right side so that the sliding column 202 moves to the right side, and the movement of the sliding column 202 can make the limiting plate 203 compress the spring 204 to the right side Move, thereby disengaging the pin 206 from the slot 207 of the composite filter screen 109, so that the composite filter plate can be taken out from the groove 108. When the composite filter plate is replaced and fixed, loosening the fixing plate 205 can move the sliding column 202 to the left, so that the limiting plate 203 can move to the left under the elastic force of the spring 204, so that the limiting plate 203 can drive the pin 206 to move to the left and insert it into the slot 207 of the composite filter plate, so as to fix the composite filter plate. The easy-to-disassemble design means that the user can easily take out the composite filter plate for regular cleaning, which helps to maintain the optimal performance of the filter and extend the service life of the filter.

[0025] like Figure 1 , 2As shown, the cleaning component includes a sliding rod 301 arranged inside the box body 101, a sliding plate 302 is slidably arranged between the two sliding rods 301, a brush plate 303 is arranged on the sliding plate 302 and contacts with the pre-filter plate 104, and a driving member for driving the sliding plate 302 to move up and down is arranged at the upper end of the box body 101.
