Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a multifunctional composite filter for household use. Background Technology

[0002] Air filters are often used in the daily use of air purification appliances to remove dust particles from the air entering the room, thereby achieving high-quality indoor air. Air filters are divided into four types: coarse, medium, sub-high efficiency, and high efficiency, and are used for filtering various gases.

[0003] Chinese utility model patent CN219663177U discloses a multifunctional air purification filter. By setting an adjustment device, the filter plate can move up and down by adhering to the surface of the mesh to cover the filter holes on the mesh. The mesh is fixed in position by pressing it with a screw ring. The size of the filter holes on the mesh can be adjusted by covering it with the filter plate. This reduces the situation where the size of the filter holes on the mesh does not match the size of the impurities in the surrounding air, which affects the filtration and improves the flexibility of the mesh.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: the device uses the up-and-down movement of the mesh to alternately cover the filter holes on the mesh, thereby enabling the device to filter impurities of different sizes. However, during the filtration process, impurities may clog the filter holes, requiring timely cleaning of the filter holes to avoid impurities clogging and affecting the filtration efficiency of the device. Therefore, we propose a household multifunctional composite filter that can shake off impurities. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a multifunctional composite filter for household use.

[0006] This utility model is achieved using the following technical solution: A household multifunctional composite filter screen includes a filter plate, a filter screen slidably connected inside the filter plate, an installation groove inside the filter plate, a bidirectional lead screw installed inside the installation groove, two threaded cylinders threaded to the outer side of the bidirectional lead screw, a helical gear A sleeved on the outer side of the bidirectional lead screw, a helical gear B meshing with the surface of helical gear A, a protective box installed on the front of the filter plate, a movable toothed plate slidably connected to the back of the inner wall of the protective box, a rotating gear meshing with the surface of the movable toothed plate, a rotating rod penetrating through the shaft of the rotating gear, the top end of the rotating rod rotatably connected to the top of the inner wall of the protective box, installation rings evenly spaced on the surface of the rotating rod, two symmetrically arranged striking plates fixedly connected to the surface of the installation rings, a connecting rod rotatably connected to the surface of the movable toothed plate, a turntable rotatably connected to one end of the connecting rod, and an electric motor fixedly connected to one end of the intermediate shaft of the turntable.

[0007] As a further improvement to the above solution, the pore size of the filter plate is larger than that of the filter screen, which facilitates graded filtration.

[0008] As a further improvement to the above solution, a connecting block is rotatably connected to the bottom end of the rotating rod, and the back of the connecting block is fixedly connected to the front of the filter plate to ensure the normal rotation of the rotating rod.

[0009] As a further improvement to the above solution, a locking strip is fixedly connected to the back of the movable toothed plate, and a slot for the locking strip to move is opened on the back of the inner wall of the protective box, ensuring the normal operation of the movable toothed plate.

[0010] As a further improvement to the above solution, two small bearings are installed on the surface of the bidirectional lead screw, and the surfaces of the small bearings are fixedly connected to the inner wall of the mounting groove, ensuring the normal rotation of the bidirectional lead screw.

[0011] As a further improvement to the above solution, two long strips are fixedly connected to the surface of the threaded cylinder. Both sides of the inner wall of the mounting groove are connected to through holes for the long strips and the threaded cylinder to pass through. Both sides of the inner wall of the filter plate are provided with insertion holes for the threaded cylinder and the long strips to be inserted. The through holes ensure the normal movement of the threaded cylinder, and the insertion holes facilitate the limiting and fixing of the threaded cylinder.

[0012] As a further improvement to the above solution, a vertical rod is fixedly connected to the shaft of the helical gear B, a handwheel is fixedly connected to the top of the vertical rod, a rotating bearing is sleeved on the surface of the vertical rod, and the surface of the rotating bearing is rotatably connected to the top of the filter screen to facilitate the rotation of the helical gear B.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a rotating rod, activates an electric motor when the filtration effect of the device deteriorates, causing the turntable to rotate. This, in turn, causes the turntable to move back and forth via a connecting rod, which in turn causes the rotating gear to reciprocate, causing the rotating rod to reciprocate. This causes the mounting ring, along with the striking plate, to strike the surface of the filter plate back and forth, resulting in the filter plate and filter screen vibrating back and forth. This dislodging of the impurities clogging the filter plate and filter screen, thus ensuring the filtration effect of the device.

[0015] 2. This utility model uses a bidirectional lead screw to insert the filter screen into the inner wall of the filter plate. Rotating the helical gear B causes the helical gear A to rotate, which in turn causes the bidirectional lead screw to rotate, causing the two threaded cylinders to move outward and insert into the slots on the filter plate. This completes the installation and fixation between the filter screen and the filter plate, making it convenient to install and remove the filter screen and to clean it. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0023] Please combine Figure 1-4This embodiment of a household multifunctional composite filter includes a filter plate 1, with a filter screen 2 slidably connected inside the filter plate 1. The aperture of the filter plate 1 is larger than that of the filter screen 2, facilitating graded filtration. An installation groove is provided inside the filter plate 1, and a bidirectional lead screw 3 is installed inside the installation groove. Two small bearings are mounted on the surface of the bidirectional lead screw 3, and the surfaces of the small bearings are fixedly connected to the inner wall of the installation groove, ensuring normal rotation of the bidirectional lead screw 3. Two threaded cylinders 4 are threadedly connected to the outer side of the bidirectional lead screw 3, and two long strips are fixedly connected to the surface of the threaded cylinders 4. Both sides of the inner wall of the installation groove have through-holes for the long strips and threaded cylinders 4 to pass through. Both sides of the inner wall of the filter plate 1 have insertion ports for the threaded cylinders 4 and long strips to be inserted. The through-holes ensure normal movement of the threaded cylinders 4, and the insertion ports facilitate limiting and fixing the threaded cylinders 4. A helical gear A5 is sleeved on the outer side of the bidirectional lead screw 3, and a helical gear B6 is meshed on the surface of the helical gear A5. A vertical rod is fixedly connected to the shaft of the helical gear B6, and a handwheel is fixedly connected to the top of the vertical rod. A rotating bearing is fitted onto the surface of the vertical rod, and the surface of the rotating bearing is rotatably connected to the top of the filter screen 2, facilitating the rotation of the helical gear B6. A protective box 7 is installed on the front of the filter plate 1, and a movable toothed plate 8 is slidably connected to the back of the inner wall of the protective box 7. A retaining strip is fixedly connected to the back of the movable toothed plate 8, and a slot for the retaining strip to move is provided on the back of the inner wall of the protective box 7 to ensure the normal operation of the movable toothed plate 8. A rotating gear 9 is meshed with the surface of the movable toothed plate 8, and a rotating rod 10 is connected through the shaft of the rotating gear 9. The bottom end of the rotating rod 10 is rotatably connected to a connecting block, the back of which is fixedly connected to the front of the filter plate 1 to ensure the normal rotation of the rotating rod 10. The top end of the rotating rod 10 is rotatably connected to the top of the inner wall of the protective box 7. Mounting rings 11 are evenly spaced on the surface of the rotating rod 10. Two symmetrically arranged striking plates 12 are fixedly connected to the surface of the mounting rings 11. A connecting rod 13 is rotatably connected to the surface of the moving toothed plate 8. One end of the connecting rod 13 is rotatably connected to a turntable 14. One end of the intermediate shaft of the turntable 14 is fixedly connected to an electric motor.

[0024] The implementation principle of a household multifunctional composite filter screen in this application embodiment is as follows: the filter screen 2 is inserted into the inner wall of the filter plate 1, the helical gear B6 is rotated, so that the helical gear B6 drives the helical gear A5 to rotate, which in turn causes the bidirectional lead screw 3 to rotate, causing the two threaded cylinders 4 to move outward, so that the two threaded cylinders 4 are inserted into the sockets on the filter plate 1, thereby completing the installation and fixation between the filter screen 2 and the filter plate 1, which facilitates the installation and disassembly of the filter screen 2 and the cleaning of the filter screen 2.

[0025] When the filtration effect of the device deteriorates, the electric motor is started, causing the turntable 14 to rotate. The turntable 14 then moves the moving toothed plate 8 back and forth via the connecting rod 13, causing the rotating gear 9 to reciprocate. This causes the rotating rod 10 to reciprocate, which in turn causes the mounting ring 11 to strike the surface of the filter plate 1 back and forth with the striking plate 12. This causes the filter plate 1 and the filter screen 2 to vibrate back and forth, shaking off the blockages on the filter plate 1 and the filter screen 2, thus ensuring the filtration effect of the device.
