Detailed Implementation

[0020] Please see Figures 1 to 4 In this embodiment of the present invention, an air purifier filter filtration effect testing device includes a testing device body 1. Slide grooves 11 are formed on the inner walls of both sides of the testing device body 1. Slide strips 12 are slidably connected inside each slide groove 11. A placement plate 6 is fixedly connected between two slide strips 12. The placement plate 6 is used to place the filter element of the air purifier filter. A cover plate 4 is connected to the testing device body 1 via a rotating shaft 3. The cover plate 4 can seal the testing device body 1. An air inlet 5 is provided on the cover plate 4 and connected to an external exhaust fan. Under the action of the exhaust fan, external air can enter the interior of the testing device body 1 through the air inlet 5, allowing the air to continuously pass through the filter element. Then, according to the gravimetric method, the filtration efficiency is calculated by measuring the weight of the dust before and after filtration. A weighing sensor inside the placement plate 6 can measure the real-time weight of the filter element.

[0021] The cover plate 4 is equipped with a nozzle 9, which is connected to an external water pump and water source. Under the action of the external water pump, the nozzle 9 can spray and clean the inside of the main body 1 of the detection device, and can clean the dust on the filter element on the surface of the placement plate 6. The placement plate 6 has multiple filter holes 7. The impurities cleaned from the filter element will fall to the bottom of the main body 1 of the detection device through the filter holes 7, and finally be discharged through the water outlet 20 on the side wall of the main body 1 of the detection device.

[0022] A drive motor 10 is installed on the side wall of the main body 1 of the detection device. The output shaft of the drive motor 10 passes through the inner wall of the main body 1 of the detection device and is fixedly connected to the rotating disk 13. When the drive motor 10 works, it drives the rotating disk 13 to rotate synchronously. A positioning post 14 is fixedly connected to the rotating disk 13. A rotating post 16 is fixedly connected to the inner wall of the main body 1 of the detection device. A limit strip 15 is rotatably connected to the rotating post 16. The limit strip 15 can rotate based on the rotating post 16. The limit strip 15 is also sleeved on the positioning post 14. When the rotating disk 13 rotates, it drives the positioning post 14 to rotate. When the positioning column 14 moves, the limiting strip 15 will swing back and forth in a fan shape based on the rotating column 16. The lower end of the limiting strip 15 is fixedly connected to the fan-shaped block 17, and the lower end of the fan-shaped block 17 is fixedly connected to multiple toothed blocks 18. The upper end of the slide bar 12 is fixedly connected to the rack 19. When the fan-shaped block 17 swings with the rotating limiting strip 15, under the action of the toothed blocks 18 and the rack 19, it will push the slide bar 12 to move back and forth along the slide groove 11, thereby driving the placement plate 6 to move back and forth, so that the filter element on the placement plate 6 can move back and forth, so that the nozzle 9 can clean it thoroughly and avoid cleaning dead corners.

[0023] The lower end of the main body 1 of the detection device is fixedly connected to a support column 2, which can support the entire detection device and ensure its stability during operation. The front end of the main body 1 of the detection device is fixedly connected to a control console 8, which can control the nozzle 9 and the drive motor 10.

[0024] The working principle of this utility model is as follows: When it is necessary to use the device to test the filtration effect of the air purifier filter element, the filter element can first be placed on the placement plate 6. Then, the cover plate 4 can be rotated by the rotating shaft 3 to seal the main body 1 of the testing device. Then, external air is discharged into the interior of the main body 1 of the testing device through the air inlet 5 by an external exhaust fan, so that it passes through the filter element. After a period of time, the air supply is stopped. At this time, the weighing sensor inside the placement plate 6 can calculate the filtration efficiency by measuring the weight of the dust before and after filtration. When it is necessary to clean the filter element containing dust, the nozzle 9 can be started by the control console 8 to clean the filter element by spraying water. The synchronous drive motor 10 starts working. The operation then synchronously drives the rotating disk 13 and the positioning column 14 to rotate, thereby pushing the limiting strip 15 to swing back and forth in a fan shape along the rotating column 16. When the limiting strip 15 moves, it also drives the fan-shaped block 17 to rotate synchronously. At this time, under the action of the meshing toothed block 18 and the toothed rack 19, the slide bar 12 will be pushed to move back and forth along the slide groove 11, thereby driving the placement plate 6 to move back and forth inside the main body 1 of the detection device. This allows the filter element to fully contact the cleaning water flow, avoids cleaning dead corners, improves the cleaning effect, and eliminates the need for staff to clean the filter element separately, which is very convenient. At the same time, it can also shake the dust off the filter element, allowing it to fall quickly from the filter hole 7, improving the cleaning efficiency. Secondly, it also facilitates repeated testing of the filter element, ensuring testing efficiency.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
