[0027] A supporting device is arranged on the water tank 10, and the pressing plate 4 is arranged on the supporting device and can rotate relative to the supporting device;

[0028] The second driving device is arranged in the water tank 10 and is used for driving the rotating rod 3 to rotate. The present invention is that water is filled in the water tank 10, the pressing plate 4 is rotated to make it in a vertical rotation state, the conductive rod of the porcelain sleeve is connected to the threaded hole on the cylinder 5 to fix it, and then the pressing plate 4 is rotated in the opposite direction to make it in a horizontal rotation state, the bottom of the porcelain sleeve contacts the brush 201 on the cleaning rod 2, and the bottom of the porcelain sleeve is immersed in water, the second driving device drives the rotating rod 3 to rotate so that the brush 201 on the cleaning rod 2 faces upward, the first driving device drives the cylinder 5 to rotate on the pressing plate 4 and then drives the porcelain sleeve to rotate, and the brush 201 on the cleaning rod 2 cleans the rotating porcelain sleeve. After the porcelain sleeve is cleaned, the pressing plate 4 is rotated to make it in a vertical rotation state, the cleaned porcelain sleeve is removed and replaced with the porcelain sleeve to be cleaned, and the second driving device drives the rotating rod 3 to rotate so that the cleaning rod 2 rotates so that the brush 201 faces downward. During the downward rotation of the brush 201, the impurities attached to the brush 201 after cleaning will fall to the bottom of the water tank 10, so as to achieve the purpose of cleaning the brush 201, and the porcelain sleeve is cleaned by being immersed in water, so that it is cleaned more cleanly. Specifically, a pipe cover is provided on the drain pipe 101, and when the water in the water tank 10 needs to be replaced, the pipe cover can be unscrewed; a plurality of supporting feet are provided at the bottom of the water tank 10; an annular clamping ring is provided on the outer wall of the cylinder 5, and a placement groove adapted to the cylinder 5 is provided on the pressure plate 4; the shape of the cleaning rod 2 can be designed according to the actual structure of the porcelain sleeve so that it is matched with the porcelain sleeve.

[0029] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0030] In this embodiment, the first driving device includes a sleeve 6, a T-shaped long round rod 7, a disc 8, a handle 9 and a fixing device. The sleeve 6 is rotatably arranged on the pressure plate 4 and connected to the cylinder 5. One end of the long round rod 7 can slide in the sleeve 6 and the other end of the long round rod 7 passes through the pressure plate 4. The disc 8 connects the long round rod 7 and the handle 9. The fixing device is used to fix the disc 8 after sliding. When cleaning the porcelain sleeve, the handle 9 is rotated to drive the long round rod 7 to rotate and then drive the sleeve 6 to rotate to rotate the cylinder 5. The brush 201 cleans the rotating porcelain sleeve. After the porcelain sleeve is cleaned, the pressure plate 4 is rotated to make the porcelain sleeve in a vertical state. One end of the long round rod 7 moves downward in the sleeve 6 to drive the disc 8 to move downward. The fixing device fixes the disc 8 to prevent the pressure plate 4 from rotating on the supporting device. Specifically, the pressure plate 4 is provided with a placement groove adapted to the sleeve 6.

[0031] In this embodiment, two first sliding grooves 601 are provided on the inner wall of the sliding sleeve 6, and two first sliding blocks 701 adapted to the first sliding grooves 601 are provided at one end of the long round rod 7. The long round rod 7 slides in the sliding sleeve 6 through the cooperation between the first sliding blocks 701 and the first sliding grooves 601. When the long round rod 7 rotates, the cooperation between the first sliding blocks 701 and the first sliding grooves 601 causes the sliding sleeve 6 to rotate, thereby driving the cylinder 5 to rotate.

[0032] In this embodiment, an annular inner cavity 801 is provided on the disc 8, and an annular rack is provided on the annular inner cavity 801; the fixing device includes an L-shaped clamping rod 11, which is meshed with the rack. When the porcelain sleeve is cleaned, the pressure plate 4 is rotated to make the porcelain sleeve in a vertical state. After the left side of the disc 8 abuts against the right side wall of the water tank 10, one end of the long round rod 7 moves downward in the sliding sleeve 6 to drive the disc 8 to move downward. The clamping rod 11 cooperates with the rack on the annular inner cavity 801 to fix the disc 8. After replacing the porcelain sleeve to be cleaned, the disc 8 is pushed upward to make one end of the long round rod 7 move upward in the sliding sleeve 6. After the disc 8 is separated from the clamping rod 11, the pressure plate 4 is rotated in the opposite direction to make it in a horizontal state, and then the porcelain sleeve is cleaned.

[0033] In this embodiment, the supporting device includes a horizontal plate 12 and two vertical plates 13, the horizontal plate 12 is provided with a long groove 121, the two vertical plates 13 are arranged on the horizontal plate 12 at intervals, and the pressing plate 4 is rotatably arranged on the two vertical plates 13. Specifically, the pressing plate 4 has protrusions on both sides, and the protrusions are rotatably connected with the vertical plates 13. When the pressing plate 4 is rotated to be vertical, the porcelain sleeve is installed or removed, and when the pressing plate 4 is rotated to be horizontal, the porcelain sleeve is cleaned. The horizontal plate 12 is provided with a long groove 121. When the pressing plate 4 is rotated to be vertical, the long round rod 7 can slide in the long groove 121 to avoid interference.

[0034] In this embodiment, the second driving device includes a rack plate 14, a gear 15 and a floating plate 16. The rack plate 14 is arranged on the floating plate 16, the gear 15 is arranged on the rotating rod 3 and meshes with the rack plate 14, and the floating plate 16 can slide on the water tank 10. When the pressing plate 4 changes from a vertical state to a horizontal state, the pressing plate 4 abuts against the rack plate 14 and applies downward pressure thereto, so that the floating plate 16 moves downward, thereby driving the gear 15 to rotate and causing the rotating rod 3 to rotate, and the brush 201 faces upward. When the pressing plate 4 changes from a horizontal state to a vertical state, the pressing plate 4 does not apply pressure to the rack plate 14, and the floating plate 16 moves upward under the action of water, driving the rack plate 14 to move upward, causing the rotating rod 3 to rotate in the opposite direction, and the brush 201 faces downward, so as to achieve the purpose of cleaning the brush 201. At the same time, when the pressing plate 4 is in a horizontal state, the rack plate 14 supports the pressing plate 4.

[0035] In this embodiment, the floating plate 16 is provided with a second slider 161, and the water tank 10 is provided with a second slide groove 102 adapted to the second slider 161. Specifically, the second slider 161 is T-shaped, and the floating plate 16 slides on the water tank 10 through the second slider 161.

[0036] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
