In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] like Figures 1 to 4 As shown, the utility model provides a self-cleaning water tank, including a shell, a water pipe assembly 20 and a folding assembly 30. The water pipe assembly 20 includes a first tube body 21, a second tube body 22 and an adapter 23, one end of the first tube body 21 is fixed to the top wall 12 of the shell, the other end of the first tube body 21 is connected to one end of the second tube body 22 through the adapter 23, the adapter 23 can be elastically bent and deformed, and the second tube body 22 is equipped with a nozzle 24 for flushing the side wall 11 of the shell; the folding assembly 30 includes an articulated seat 31, a first connecting rod 32 and a second connecting rod 33, the articulated seat 31 is fixed to the top of the shell, one end of the first connecting rod 32 is hinged to the articulated seat 31 through a first articulated shaft, one end of the second connecting rod 33 is hinged to the other end of the first connecting rod 32 through a second articulated shaft, and the other end of the second connecting rod 33 is hinged to the second tube body 22 through a third articulated shaft, and the first articulated shaft, the second articulated shaft and the third articulated shaft are all parallel to the first direction.

[0037] Assume that the liquid contained in the shell is the first liquid, and the liquid used by the water pipe assembly 20 to flush the shell is the second liquid. The first liquid and the second liquid are different liquids. It should be noted that the different liquids here can be understood as different chemical compositions or different purities. In this embodiment, the first liquid is circulating water, which is easy to form scale on the inner wall of the shell, and the second liquid is soft water.

[0038] Specifically, the housing is used to store the first liquid. When the first liquid is stored in the housing, the internal space of the housing is divided into a water area and a water-free area in the vertical direction, that is, the first liquid does not fill the housing. The water pipe assembly 20 includes an extended state and a retracted state. When in the extended state, the first pipe body 21 and the second pipe body 22 are coaxially arranged and extend in the vertical direction, with a part located in the water area and the other part located in the water-free area. When in the retracted state, the second pipe body 22 is arranged at an angle with the first pipe body 21, and the second pipe body 22 is close to the top wall 12 of the housing. At this time, the water pipe assembly 20 is entirely located in the water-free area. The folding assembly 30 is used to assist the water pipe assembly 20 to complete the switching between the retracted state and the extended state. When the water pipe assembly 20 is in the extended state, the first connecting rod 32 is located at the first position. When it is necessary to switch from the extended state to the retracted state, the first connecting rod 32 rotates towards the top wall 12 of the housing and drags the second pipe body 22 to rotate relative to the first pipe body 21 through the second connecting rod 33, and they rotate towards the top wall 12 of the housing together.

[0039] When the first liquid is stored in the housing, the water pipe assembly 20 is always in the retracted state. In this way, the contact between the water pipe assembly 20 and the first liquid can be reduced, avoiding the water pipe assembly 20 being eroded by the first liquid or the formation of water scale on the surface of the water pipe assembly 20, which is difficult to clean later. When it is necessary to clean the side wall 11 of the housing, the first liquid in the housing is emptied, and the water pipe assembly 20 is switched to the extended state. The second liquid flows through the first pipe body 21 and the second pipe body 22 in sequence and is sprayed from the nozzle 24 onto the side wall 11 of the housing to clean the side wall 11 of the housing. In this way, it is possible to avoid personnel entering the housing for cleaning, realizing the self-cleaning function of the water tank.

[0040] Optionally, the folding assembly 30 further includes a third pipe body 25 and a limit slider 26. A nozzle 24 is installed on the third pipe body 25. One end of the third pipe body 25 communicates with the other end of the second pipe body 22 through an adapter 23. The other end of the third pipe body 25 is hinged to the limit slider 26 through a fourth hinge shaft. A chute is formed on the side wall 11 of the housing along the second direction X. The limit slider 26 is slidably inserted into the chute. The fourth hinge shaft is parallel to the first direction, and the second direction X is perpendicular to the first direction. With such a setting, by additionally providing the third pipe body 25, the extension length of the water pipe assembly 20 is extended. That is, when the water pipe assembly 20 is in the extended state, the first pipe body 21, the second pipe body 22, and the third pipe body 25 are coaxially arranged, and the side wall 11 of the housing with a larger area can be cleaned. The third pipe body 25 is connected to the side wall 11 of the housing through the limit slider 26. Specifically, a chute is formed on the side wall 11 of the housing, and the chute is in an inverted T shape. The limiting portion of the limit slider 26 is inserted into the chute, so that the limit slider 26 can only slide relative to the housing along the second direction X. When the second connecting rod 33 pulls the second pipe body 22 toward the top wall 12 of the housing, the second pipe body 22 flips toward the top wall 12 of the housing. At the same time, the second pipe body 22 drives one end of the third pipe body 25 to flip toward the top wall 12 of the housing, and the other side of the third pipe body 25 drives the limit slider 26 to move toward the top wall 12 of the housing along the second direction X, completing the switching to the storage state.

[0041] Optionally, a roller is rotatably connected to the limit slider 26. The roller is located in the chute and can slide relative to the bottom wall or the two side walls 11 of the chute. With such a setting, the slider forms a rolling friction with the inner wall of the chute through the roller, reducing the friction between the two, making it easier for the third pipe body 25 to switch to the storage state.

[0042] Optionally, the folding assembly 30 further includes a cylinder 34 and a swing arm 35. The cylinder 34 is installed outside the housing. The output end of the cylinder 34 is hinged to the swing arm 35 through a fifth hinge shaft. The other end of the swing arm 35 is fixed to the first connecting rod 32. The output end of the cylinder 34 moves along the third direction Y, which can make the first connecting rod 32 rotate around the first hinge shaft. The fifth hinge shaft is parallel to the first direction, and the first direction, the second direction X, and the third direction Y are all perpendicular. Specifically, the cylinder 34 is hinged to the housing through a sixth hinge shaft, and the sixth hinge shaft is parallel to the first hinge shaft. The swing arm 35 and the first connecting rod 32 are fixed to form a lever, which can rotate around the first hinge shaft with the hinge seat 31 as the fulcrum. In this embodiment, when the output end of the cylinder 34 extends, one end of the lever is offset to the side away from the side wall 11 of the housing, and the other end of the lever drives the second connecting rod 33 to approach the side wall 11 of the housing, and the second connecting rod 33 then pushes the second pipe body 22 toward the side wall 11 of the housing. When the water pipe assembly 20 needs to be switched to the storage state, the output end of the cylinder 34 moves in the reverse direction, and the linkage process will not be repeated here.

[0043] Optionally, the swing arm 35 is integrally formed with the first connecting rod 32.

[0044] Optionally, a plurality of nozzles 24 are arranged along the axial direction of the second pipe body 22. With such an arrangement, by providing a plurality of nozzles 24, the side wall 11 of the housing can be flushed more comprehensively.

[0045] Preferably, the nozzle 24 is a high-pressure nozzle 24.

[0046] Optionally, the water pipe assembly 20 further includes a fourth pipe body, which is connected between the second pipe body 22 and the third pipe body 25 through an adapter 23, and the fourth pipe body is provided with nozzles 24.

[0047] Optionally, the nozzle 24 is rotatably connected to the second pipe body 22. In this way, when flushing the side wall 11 of the housing, the nozzle 24 swings relative to the second pipe body 22, which can expand the spraying range of the nozzle 24.

[0048] Optionally, the housing includes a plurality of side walls 11, and each side wall 11 is configured with a water pipe assembly 20 and a folding assembly 30.

[0049] Furthermore, an external clean water tank is provided outside the self-cleaning water tank. A second liquid is stored in the clean water tank. A water pump is installed in the clean water tank. The water pump is communicated with the first pipe body 21 through a water injection pipe. An electromagnetic valve is provided on the water injection pipe. When the electromagnetic valve is opened, the water pump can introduce the second liquid in the clean water tank into the water pipe assembly 20.
