Detailed implementation manner

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0041] The air purification device includes a filter screen. After long-term use, the filter screen will adsorb a large amount of dust and dirt. In order to reduce the frequency of manual cleaning of the filter screen and improve the user's convenience of use, some air purification devices are equipped with a filter screen self-cleaning function, which can automatically remove the dust and dirt on the filter screen and keep the filter screen clean, thereby ensuring the efficient operation of the air purification device and good air circulation.

[0042] The related art discloses an air purifier filter cleaning device, including a front filter frame, a rear filter frame, a filter, a driving mechanism and a filter brush. The front filter frame and the rear filter frame are arranged opposite to each other. One end of the filter is clamped inside the front filter frame, and the other end is clamped inside the rear filter frame. The driving mechanism is connected to the filter and can drive the filter to move reciprocally. The filter brush is arranged at the turning point of the filter and contacts the turning point of the filter. By driving the filter to move reciprocally, the surface of the filter is cleaned by the filter brush. The driving mechanism is a driving motor with gears connected to each other. A rack meshing with the gears is arranged on the filter. The filter is driven to move by the gears, and the structure is simple and stable. The filter brush is a roller brush, and the roller brush is connected to the output shaft of the motor. The cleaning effect is better through the relative movement between the roller brush and the filter.

[0043] In the above related art, it is necessary to provide both a driving motor for driving the filter to move reciprocally and a motor for driving the roller brush to rotate, resulting in a large number of components and high costs.

[0044] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 16 , and describe the embodiments of the present invention.

[0045] According to an embodiment of the present invention, on the one hand, a device with a filter is provided, including a filtering component, a cleaning component and a driving component.

[0046] Among them, the filtering component includes a filter 100; the cleaning component includes a dust removal brush 200, and the dust removal brush 200 is arranged on one side of the filter 100 and is adapted to contact the filter 100; the driving component includes a driving motor 300 and a transmission mechanism, and the transmission mechanism simultaneously drives the filter 100 and the dust removal brush 200 to rotate.

[0047] In this embodiment, the driving component includes a driving motor 300 and a transmission mechanism, and the transmission mechanism simultaneously drives the filter 100 and the dust removal brush 200 to rotate. Since the dust removal brush 200 is arranged on one side of the filter 100 and contacts the filter 100, during the rotation of the filter 100 and the dust removal brush 200, the dust removal brush 200 can brush off the dust and dirt adhered to the filter 100, thereby realizing the cleaning of the filter 100. Since the filter 100 and the dust removal brush 200 can rotate simultaneously, the cleaning effect can be improved. And because one driving motor 300 drives the filter 100 and the dust removal brush 200 to rotate simultaneously through the transmission mechanism, compared with the related art, the number of components can be reduced and the cost can be lowered.

[0048] Specifically, as shown in Figure 11 and Figure 12 , the filter 100 is cylindrical, and air passes through the filter 100 radially. The filter 100 can filter out dust and dirt in the air.

[0049] It should be noted that the rotation directions of the dust removal brush 200 and the filter screen 100 can be the same or opposite.

[0050] Specifically, in one embodiment, the device with the filter screen is an air purification device.

[0051] In one embodiment, the transmission mechanism includes a turntable 301 and a dust box gear 302 that is in transmission connection with the turntable 301. The dust box gear 302 is connected to the dust removal brush 200. The filter assembly is arranged on the turntable 301, and the driving motor 300 is in transmission connection with the turntable 301.

[0052] In this embodiment, since the filter assembly is arranged on the turntable 301 and the driving motor 300 is in transmission connection with the turntable 301, the driving motor 300 can drive the turntable 301 to rotate, thereby driving the filter assembly to rotate. Since the dust box gear 302 is in transmission connection with the turntable 301, the rotation of the turntable 301 can drive the dust box gear 302 to rotate at the same time, thereby driving the dust removal brush 200 to rotate. Therefore, it can be realized that one driving motor 300 drives the filter screen 100 and the dust removal brush 200 to rotate at the same time. Compared with the related art, the number of components can be reduced and the cost can be lowered.

[0053] In an embodiment not shown in the figure, the turntable 301 can be not provided. The output shaft of the driving motor 300 is directly connected to the bottom center of the filter assembly. The output shaft of the driving motor 300 is connected to a driving gear. The dust box gear 302 is connected to the dust removal brush 200, and the dust box gear 302 is meshed with or in transmission connection with the driving gear. Similarly, it can be realized that one driving motor 300 drives the filter screen 100 and the dust removal brush 200 to rotate at the same time. Compared with the related art, the number of components can be reduced and the cost can be lowered.

[0054] In one embodiment, as Figure 7 shown, the turntable 301 is provided with a first gear meshing portion 3011 and a second gear meshing portion 3012. The first gear meshing portion 3011 and the second gear meshing portion 3012 are coaxially arranged. The driving motor 300 is in transmission connection with the first gear meshing portion 3011, and the dust box gear 302 is meshed with the second gear meshing portion 3012.

[0055] In this embodiment, by providing the turntable 301 with a first gear engagement portion 3011 and a second gear engagement portion 3012, the first gear engagement portion 3011 and the second gear engagement portion 3012 are coaxially arranged. The driving motor 300 is in transmission connection with the first gear engagement portion 3011. When the driving motor 300 operates, it drives the first gear engagement portion 3011 to rotate, thereby driving the entire turntable 301 to rotate, and further driving the filter assembly to rotate. Since the dust box gear 302 is engaged with the second gear engagement portion 3012, the rotation of the turntable 301 can drive the dust box gear 302 to rotate simultaneously, and further drive the dust removal brush 200 to rotate. Therefore, one driving motor 300 can drive the filter screen 100 and the dust removal brush 200 to rotate simultaneously. By providing the turntable 301 with the first gear engagement portion 3011 and the second gear engagement portion 3012, the number of gears provided can be reduced, the number of components is smaller, the cost can be reduced, and it is convenient for assembly. The direct engagement between the dust box gear 302 and the second gear engagement portion 3012 can further reduce the number of components, save costs, and facilitate assembly.

[0056] In an embodiment not shown in the figure, the turntable 301 can be provided with only the second gear engagement portion 3012, and the output shaft of the driving motor 300 is directly connected to the center of the turntable 301. In the above embodiment, by providing the first gear engagement portion 3011 on the turntable 301 and the driving motor 300 being in transmission connection with the first gear engagement portion 3011, a speed reduction effect can be achieved to prevent the turntable 301 from rotating too fast.

[0057] In an embodiment, the transmission mechanism further includes a driving gear 303 connected to the output shaft of the driving motor 300, and the driving gear 303 is engaged with the first gear engagement portion 3011.

[0058] In this embodiment, the driving gear 303 is connected to the output shaft of the driving motor 300 and is engaged with the first gear engagement portion 3011. When the driving motor 300 operates, it drives the driving gear 303 to rotate, and further drives the first gear engagement portion 3011 to rotate, thereby driving the entire turntable 301 and the filter assembly to rotate. Since the dust box gear 302 is in transmission connection with the second gear engagement portion 3012, the rotation of the turntable 301 can drive the dust box gear 302 to rotate simultaneously, and further drive the dust removal brush 200 to rotate.

[0059] Specifically, in an embodiment, the number of teeth of the first gear engagement portion 3011 is greater than the number of teeth of the driving gear 303, so as to achieve a speed reduction effect.

[0060] In an embodiment not shown in the figure, a gear set can be used for transmission between the driving motor 300 and the first gear engagement portion 3011.

[0061] Specifically, in one embodiment, the number of teeth of the dust box gear 302 is less than that of the second gear engagement part 3012, and the number of teeth of the second gear engagement part 3012 is greater than that of the first gear engagement part 3011.
