[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a self-cleaning box-type variable frequency water supply device, including a water tank 1, a water pump 2, a piping system 3, and a control cabinet 5. The water pump 2 is bolted and sealed at the output pipe of the water tank 1, and the piping system 3 is bolted and sealed at the output pipe of the water pump 2. An electric wire 4 is installed on the water pump 2, and the end of the electric wire 4 is electrically connected to the control cabinet 5. The control cabinet 5 is located to the left of the water pump 2. A drain pipe 6 is provided at the center of the bottom curved surface of the water tank 1, and a sealing cover 7 is sleeved on the bottom of the drain pipe 6. A positioning joint 8 is fixedly installed at the center of the end face of the water tank 1, and a supporting water pipe 9 is installed through the center of the frame of the water tank 1 and the positioning joint 8.

[0025] The sealing cover 7 is connected to the drain pipe 6 by a threaded connection. The internal space of the drain pipe 6 is connected to the internal space of the water tank 1. The connection point between the drain pipe 6 and the internal space of the water tank 1 is the lowest point inside the water tank 1. This facilitates the discharge of dirt through the drain pipe 6 after the inner wall of the water tank 1 is rinsed.

[0026] The support water pipe 9 is connected to the positioning connector 8 and the water tank 1 by a rotary sliding connection. The support water pipe 9 is symmetrically distributed on the water tank 1. The symmetrical distribution of the support water pipe 9 is beneficial to the efficiency of subsequent cleaning of the inner wall of the water tank 1. At the same time, the support water pipe 9 can be adjusted in position and fixed by rotary sliding.

[0027] A connecting cover 10 is fitted onto the outer surface of the supporting water pipe 9, and the connecting cover 10 is connected to the positioning connector 8. A sealing ring 11 is glued and fixed inside the connecting cover 10. The supporting water pipe 9 and the connecting cover 10 are connected by welding, and the connecting cover 10 and the positioning connector 8 are connected by thread. The sealing ring 11 and the positioning connector 8 are connected by a fitted seal. The connecting cover 10 and the positioning connector 8 can be combined and fixed. At the same time, the sealing ring 11 can seal the connection to prevent water leakage.

[0028] A connecting flange 12 is fixedly installed at the outer end of the supporting water pipe 9, and a connecting pipe 13 is installed at the inner end of the supporting water pipe 9. The connecting pipe 13 is located inside the water tank 1. A convex ball 14 is provided on the outer surface of the connecting pipe 13, and a combination sleeve 15 is sleeved on the outer side of the connecting pipe 13 and the convex ball 14. A rubber ring 16 is glued and fixedly installed inside the combination sleeve 15, and a hollow ball 17 is provided at the end of the combination sleeve 15. A jet pressure hole 18 is opened on the frame of the hollow ball 17. The connecting pipe 13 and the supporting water pipe 9 are integrated into one structure, and the internal space of the connecting pipe 13 is interconnected with the internal space of the supporting water pipe 9 and the hollow ball 17. The connecting pipe 13 and the supporting water pipe 9 form a "T" shaped structure. According to the structure of the supporting water pipe 9 and the connecting pipe 13, it is conducive to the all-round coverage of subsequent rinsing.

[0029] The combined sleeve 15 and the hollow ball 17 are integrated into one structure. The hollow ball 17 has spray holes 18 distributed at equal angles, and the diameter of the spray holes 18 gradually decreases from the inside to the outside. The combined sleeve 15 is connected to the connecting pipe 13 by a rotating connection through the convex ball 14. The convex ball 14 and the connecting pipe 13 are integrated into one structure, and the convex ball 14 is distributed at equal angles on the connecting pipe 13. The connecting pipe 13 is connected to the rubber ring 16 by a close-fitting seal. The hollow ball 17 can rotate at the end of the connecting pipe 13 through the combined sleeve 15. The spray holes 18 on the hollow ball 17 facilitate the high-pressure water jet for cleaning. During the cleaning process, the hollow ball 17 can rotate by water pressure and impact force to perform self-cleaning.

[0030] Working principle: According to Figures 1 to 6 This box-type variable frequency water supply equipment connects to an external water pipe via an inlet pipe on water tank 1. The water stored inside water tank 1 is controlled by control cabinet 5 via wire 4 to operate water pump 2, which transports the water inside water tank 1 to the pipeline system 3 for distribution. When water tank 1 is used for a long time and water grooves form on its inner wall requiring cleaning, the water inside water tank 1 is drained. This is achieved by sealing the support water pipe 9 with an external water supply device via connecting flange 12, allowing for high-pressure water transport inside the support water pipe 9. Water can enter the combined sleeve 15 and hollow sphere 17 through the support water pipe 9 and connecting pipe 13. Through the distribution and structure of the jet pressure holes 18 on the hollow sphere 17, water can be ejected to flush the inner wall of water tank 1. Based on the water pressure and the impact force generated during the rinsing process, the hollow ball 17 can rotate on its own through the connection between the combined sleeve 15 and the connecting pipe 13. The combined sleeve 15 and the connecting pipe 13 are rotatably connected by the convex ball 14, which improves the flexibility of rotation and allows for all-round automatic rinsing of the inside of the water tank 1. The wastewater generated during subsequent rinsing can be discharged from the drain pipe 6 by opening the sealing cover 7. The supporting water pipe 9 is assembled and fixed according to the threaded connection between the connecting cover 10 and the sealing ring 11 and the positioning joint 8. At the same time, it can be disassembled to adjust the position of the hollow ball 17 inside the water tank 1 for convenient cleaning. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
