DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, an air filtering device with a cleaning function comprises: a filter box 1, the inner wall of which is fixedly connected with a filter plate 2; a cleaning mechanism 3, which is used to clean the filter plate 2 and is arranged at the top of the filter plate 2; wherein the cleaning mechanism 3 comprises a collecting box 301 fixedly connected to one side of the filter box 1, a first fan 302 is installed at the top of the collecting box 301, a dust suction frame 303 is slidably connected to the inner wall of the filter box 1, a dust suction pipe 304 is arranged inside the collecting box 301, one end of the dust suction pipe 304 passes through the collecting box 301 and the filter box 1 in sequence and is fixedly connected to the top of the dust suction frame 303, and a cleaning component 305 is arranged at the bottom of the filter plate 2.

[0026] A filter plate is installed on the top of the filter box 1, and the diameter of the filter plate mesh is larger than the diameter of the filter plate 2 mesh. The inner wall of the filter box 1 is fixedly connected with the same activated carbon filter as in the original scheme, and is arranged below the filter plate 2. The inner wall of the filter box 1 is installed with a guide plate and a driving fan body, and the guide plate is arranged below the activated carbon filter. The air inlet of the driving fan body is connected to the guide plate, and the air outlet of the driving fan body is connected to the bottom cavity of the filter box 1.

[0027] When filtering the air, start the driving fan body, the outside air will enter the interior of the filter box 1, the filter plate on the top of the filter box 1 will filter the larger impurities in the air, the filter plate 2 will filter the dust in the air, and the filtered air passes through the activated carbon filter plate and is discharged from the cavity at the bottom of the filter box 1 through the air outlet of the driving fan body, thereby completing the air filtering operation. When the filter plate 2 is cleaned regularly, start the first fan 302 to discharge the air in the collection box 301, so that a negative pressure is formed in the collection box 301. The collection box 301 is filled with an aqueous solution. When a negative pressure is formed in the collection box 301, the dust suction pipe 304 and the dust suction frame 303 can adsorb the dust on the filter plate 2.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cleaning assembly 305 includes a connecting rod 3053 that is slidably connected to the inner wall of the filter box 1, a circular tube 3051 is fixedly connected to one side of the connecting rod 3053, a mounting cylinder 3052 is fixedly connected to the inner wall of the filter box 1, and one end of the mounting cylinder 3052 passes through the filter box 1, a bellows 3054 is fixedly connected to the inner wall of the mounting cylinder 3052, the other end of the bellows 3054 is fixedly connected to the front end of the connecting rod 3053, one end of the bellows 3054 passes through the mounting cylinder 3052 and is fixedly connected to a connecting pipe 3055, a hose 3056 is arranged between the connecting pipe 3055 and the circular tube 3051, and the upper end of the surface of the circular tube 3051 is provided with air outlet holes 3057 distributed in equal rows. The inner wall of the filter box 1 is rotatably connected with a threaded rod 3058, and the surface of the threaded rod 3058 is threadedly connected with a moving rod 3059, one side of the moving rod 3059 is fixedly connected with one end of the dust collection frame 303, and the bottom end of the moving rod 3059 and the top end of the connecting rod 3053 are fixedly connected with a magnetic block 30510, and the end of the magnetic block 30510 is in contact with the surface of the filter plate 2. The inner wall of the filter box 1 is fixedly connected with a circular ring 306, and the threaded rod 3058 is arranged on the inner side of the circular ring 306, and the surface of the moving rod 3059 is slidably connected with the inner wall of the circular ring 306. The inner wall of the filter box 1 is fixedly connected with a limiting rod 308, and the inner wall of the connecting rod 3053 is slidably connected with the surface of the limiting rod 308.

[0029] The dust collection frame 303 and the circular tube 3051 are arranged on the same vertical plane. When the device performs normal filtering operation, the dust collection frame 303 and the circular tube 3051 are located on one side of the filter plate 2, which does not affect the normal air filtering operation. One end of the threaded rod 3058 passes through the filter box 1 and is fixedly connected with a knob. When the dust collection tube 304 and the dust collection frame 303 perform dust collection operation, the knob is turned to rotate the threaded rod 3058 to rotate the moving rod 3059 along the inner wall of the circular ring 306, thereby driving the dust collection frame 303 to move horizontally along the top of the filter plate 2 to perform dust collection operation. The middle part of the dust collection tube 304 can be stretched. At the same time, since the two magnetic blocks 30510 are strong magnetic blocks 30510 and the two magnetic blocks 30510 are attracted to each other, the attraction between the two magnetic blocks 30510 is due to the magnetic field generated between them. Due to the interaction, the opposite ends of the two magnetic blocks 30510 are different poles. Therefore, the two magnetic blocks 30510 will attract each other. When the moving rod 3059 moves, the two magnetic blocks 30510 will move synchronously, thereby driving the connecting rod 3053 to move along the surface of the limiting rod 308 and making the circular tube 3051 move synchronously. When the connecting rod 3053 moves, it will squeeze the bellows 3054. After being squeezed, the gas in the bellows 3054 will enter the circular tube 3051 through the connecting tube 3055 and the hose 3056 in turn, and be blown out through the air outlet 3057. At this time, the air outlet 3057 will blow the dust on the filter plate 2 at the corresponding position below the dust suction frame 303 upwards, and under the action of the dust suction frame 303 and the dust suction pipe 304, the dust will be sucked into the collection box 301, and dissolved using an aqueous solution.

[0030] like Figure 5 As shown, a first one-way valve 30511 is provided on the surface of the connecting pipe 3055 , an air inlet pipe 30512 is provided on the other end of the bellows 3054 , and a second one-way valve 30513 is provided on the surface of the air inlet pipe 30512 .

[0031] When the dust collection frame 303 and the circular tube 3051 move to the other side of the filter plate 2, at this time, the threaded rod 3058 is rotated in the opposite direction to drive the moving rod 3059 and the connecting rod 3053 to move in the opposite direction. Under the action of the air inlet pipe 30512, the external gas will enter the bellows 3054. The air inlet pipe 30512 is a one-way air inlet pipe 30512 under the action of the second one-way valve 30513, and the connecting pipe 3055 can only discharge gas in one direction under the action of the first one-way valve 30511. Therefore, when the external gas enters the bellows 3054 through the air inlet pipe 30512, the connecting pipe 3055 does not operate.

[0032] like Figure 4As shown, a cleaning block 307 is fixedly connected to one side of the upper magnetic block 30510, and the shape of the cleaning block 307 is a right triangle. The bottom end of the cleaning block 307 fits with the top end of the filter plate 2, and when the upper magnetic block 30510 moves, it pushes the cleaning block 307 to move and clean the impurities at the front end of the upper magnetic block 30510.

[0033] like Figure 4 As shown, the inner wall of the dust collecting frame 303 is in the shape of an isosceles triangle. When the dust collecting frame 303 is performing a dust collecting operation, dust will enter the dust collecting pipe 304 through the inclined surface of the inner wall of the dust collecting frame 303 .

[0034] When the utility model is in use, when filtering the air, the fan body is started and driven to introduce the outside air into the filter box 1, the filter plate at the top of the filter box 1 will filter the larger impurities in the air, the filter plate 2 will filter the dust in the air, and the filtered air will be discharged through the cavity at the bottom of the filter box 1, thereby completing the air filtering operation.

[0035] When the filter plate 2 is cleaned regularly, the first fan 302 is started to exhaust the air in the collection box 301, so that a negative pressure is formed in the collection box 301. At this time, the dust suction pipe 304 and the dust suction frame 303 can absorb the dust on the filter plate 2, and the threaded rod 3058 is rotated to move the moving rod 3059, thereby driving the dust suction frame 303 to move horizontally along the top of the filter plate 2 to perform the dust suction operation. When the moving rod 3059 moves, it drives the two magnetic blocks 30510 to move synchronously, thereby driving the connecting rod 3053 and The circular tube 3051 is made to move synchronously and squeeze the bellows 3054. After being squeezed, the gas in the bellows 3054 will enter the circular tube 3051 through the connecting tube 3055 and the hose 3056 in turn, and be blown out through the air outlet 3057. At this time, the air outlet 3057 will blow the dust on the filter plate 2 at the corresponding position below the dust suction frame 303 upwards, and under the action of the dust suction frame 303 and the dust suction tube 304, the dust will be sucked into the collection box 301, and dissolved with an aqueous solution to complete the cleaning of the filter plate 2.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
