[0031] Reference Figure 2 , Figure 3 and Figure 4 In order to improve the cleaning effect of the cleaning roller 61, a driving device 9 is installed in the outer cylinder 3 to drive the cleaning roller 61 to rotate. The driving device 9 includes a gear ring 91, a connecting shaft 92, a driving gear 93, a first bevel gear 94, and a second bevel gear 95. The gear ring 91 is fixedly installed at the end of the cylinder 2 away from the sealing door 11, the tooth surface of the gear ring 91 is away from the end surface of the cylinder 2, and the center line of the gear ring 91 coincides with the center line of the cylinder 2.

The cleaning roller 61 can be driven to rotate by the rotation of the cylinder 2 .

[0032] Reference Figure 2 , Figure 3 and Figure 4The connecting shaft 92 is a retractable structure, which can ensure that when the cleaning roller 61 rotates along the outer wall of the cylinder 2, the first bevel gear 94 and the second bevel gear 95 can always fit together. The connecting shaft 92 includes a sleeve 921, a connecting rod 922 and a movable rod 923. The sleeve 921 is rotatably connected to the first bracket 31, and the second bracket 63 is fixedly installed at the end of the mounting frame 62. The connecting rod 922 is rotatably connected to the second bracket 63. The driving gear 93 is fixedly installed at the lower end of the sleeve 921, and the first bevel gear 94 is fixedly installed at the upper end of the connecting rod 922. The movable rod 923 is inserted into the sleeve 921 and slidably cooperates with the sleeve 921. A limiting groove 924 arranged along the height direction is opened in the sleeve 921. A limiting block 925 is fixed on one side of the movable rod 923, and the limiting block 925 is slidably connected to the limiting groove 924, so that the movable rod 923 can only slide along the height direction of the sleeve 921, but cannot rotate along the center line of the sleeve 921. The axes of the sleeve 921, the connecting rod 922 and the movable rod 923 are located on the same straight line. The connecting rod 922 is connected to the sleeve 921 through a connecting device 10, so that the sleeve 921 and the connecting rod 922 rotate synchronously. The connecting device 10 includes a first end face gear 101, a second end face gear 102, and a connecting spring 103.

The connecting spring 103 is sleeved outside the sleeve 921, and the two ends of the connecting spring 103 are respectively fixedly connected to the sleeve 921 and the second end face gear 102. Under the action of the connecting spring 103, when the height of the cleaning roller 61 changes, the first end face gear 101 and the second end face gear 102 can always be meshed, thereby driving the cleaning roller 61 to rotate.

[0033] Reference Figure 2 , Figure 3 and Figure 4In order to store the cleaning roller 61, a lifting device 20 is installed in the storage box 5. The lifting device 20 includes a lifting motor 201, a storage roller 202, and a connecting rope 203. The lifting motor 201 is fixedly installed on the inner top wall of the storage box 5. The storage roller 202 is rotatably installed on the inner top wall of the storage box 5, and the rotation axis of the storage roller 202 is consistent with the length direction of the storage box 5. One end of the connecting rope 203 is wound on the storage roller 202, and the other end of the connecting rope 203 is fixedly installed on the upper end surface of the mounting frame 62 and is located at the center. By starting the lifting motor 201, the connecting rope 203 can be wound and retracted, and then the mounting frame 62 can be lifted, so that the cleaning roller 61 is stored inside the storage box 5 away from the cylinder 2. The height of the storage box 5 is much higher than the overall height of the mounting frame 62, so that the first end face gear 101 can be stored inside the storage box 5. After the connecting rope 203 is released, the cleaning roller 61 can always fit the outer surface of the cylinder 2 under the action of the tension spring 83 .

[0034] Reference Figure 1 , Figure 2 The outer cylinder 3 is provided with a sealing device 30, which can seal the bottom of the storage box 5 after the cleaning roller 61 is stored in the storage box 5, thereby improving the safety and reliability of the overall use. The sealing device 30 includes a sealing plate 301 and a sealing cylinder 302. The sealing cylinder 302 is fixedly installed on the inner wall of the body 1. A sealing port is provided at the connection between the storage box 5 and the outer cylinder 3. The sealing plate 301 is slidably arranged on the outer cylinder 3, and one end of the sealing plate 301 is inserted into the sealing port, and is fixedly connected to one side of the sealing plate 301 through the telescopic end of the sealing cylinder 302. In order to improve the safety of the cleaning roller 61, the sealing plate 301 can be driven to pass through the bottom of the storage box 5 and seal the opening connecting the storage box 5 and the outer cylinder 3 by starting the sealing cylinder 302.

[0035] Reference Figure 3 , Figure 5The second cleaning device 7 includes a cleaning brush 71, a first mounting rod 72, and a second mounting rod 73. The cleaning brush 71 is arranged along the length direction of the cylinder 2, and the bristles 712 of the cleaning brush 71 are in contact with the inner wall of the cylinder 2. The first mounting rod 72 and the second mounting rod 73 are respectively fixedly mounted on the two ends of the cleaning brush 71, and are perpendicular to the cleaning brush 71. The end of the first mounting rod 72 is rotatably connected to the center of the end of the cylinder 2, and one end of the second mounting rod 73 is in contact with the sealing door 11 of the body 1. When the cylinder 2 rotates, since the end of the second mounting rod 73 is in contact with the sealing door 11, there is a certain friction force, and the cleaning brush 71 is relatively fixed, so that the cylinder 2 rotates around the cleaning brush 71, and the inner wall of the cylinder 2 can be cleaned. The lock body 71 is fixedly mounted on the fixing plate 74 of the fixing plate 76. The fixing plate 76 is provided with a fixing spring 75 at two ends of the fixing plate 76. The fixing plate 76 is fixedly mounted on the fixing plate 76.

[0036] On the other hand, refer to Figure 2 and Figure 3 The embodiment of the present application discloses a washing machine inner drum with a self-cleaning barrel wall function. The inner wall of the barrel 2 is fixedly mounted with convex strips. There are multiple convex strips evenly arranged along the circumference of the barrel 2. The convex strips are formed by being recessed inward along the outer wall of the barrel 2. The edges of the convex strips are all formed with rounded corners. The barrel 2 is provided with a plurality of evenly arranged liquid seepage holes 22. The liquid seepage holes 22 are formed by the inner wall of the barrel 2 being recessed outward. The aperture of the liquid seepage hole 22 located on the inner side is larger than the aperture of the liquid seepage hole 22 located on the outer side. A cleaning brush 71 is rotatably connected inside the barrel 2. The cleaning brush 71 includes a brush rod 711 and bristles 712. The bristles 712 are evenly arranged along the surface of the brush rod 711 close to the inner wall of the barrel 2. The brush rod 711 is spaced apart from the surface of the convex strips. The bristles 712 abut against the barrel wall of the barrel 2. When the barrel 2 rotates, the cleaning brush 71 rotates relative to the barrel 2 to clean the inner wall of the barrel 2.

[0037] The working principle of the embodiment of the present application is: by starting the braking device 4, the cylinder 2 can be driven to rotate. Since a driving device 9 is installed between the cylinder 2 and the outer cylinder 3, the cleaning roller 61 can be driven to rotate to clean the outer wall of the cylinder 2, and one end of the cleaning brush 71 is rotatably connected to the end of the cylinder 2, and the other end of the cleaning brush 71 is tightly pressed against the sealing door 11. When the cylinder 2 rotates, the cleaning brush 71 is relatively fixed and can clean the inner wall of the cylinder 2. Combined with the cleaning of the inner and outer walls of the cylinder 2, the self-cleaning effect of the cylinder 2 can be enhanced.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
