The screw 2 is rotatably installed on the connecting seat 1 via a bearing 26 and is driven to rotate by a drive motor 21. Both the bearing 26 and the drive motor 21 are fixedly installed inside the connecting seat 1. A screw cylinder 22 is threadedly connected to the outer circumference of the portion of the screw 2 away from the connecting seat 1. A telescopic rod 23 is fixedly installed on the outer circumference of the screw cylinder 22 via bolts 25. The telescopic rod 23 is cylindrical and sleeved on the outer circumference of the screw cylinder 22, with a clearance 24 between them. A wire is stored in the clearance 24. A connector 234 is also installed at the end of the telescopic rod 23 away from the connecting seat 1. The wire connects from the connecting seat 1 to the connector 234 of the telescopic rod 23, mainly for supplying power to the cleaning head 5.

[0036] An outer cylinder 4 is fixedly installed at the other end of the connecting seat 1 relative to the spray bottle 3. The outer cylinder 4 is sleeved on the outer periphery of the telescopic rod 23. The outer cylinder 4 and the telescopic rod 23 are axially slidingly adapted to each other and can restrict axial rotation. Specifically, guide grooves or flat parts can be used to achieve the limiting.

[0037] The telescopic rod 23, driven by the screw 2, can extend and retract relative to the outer cylinder 4 along the axial direction. The end of the telescopic rod 23 away from the connecting seat 1 protrudes from the outer cylinder 4, forming an annular boss 232. The annular boss 232 allows for the detachable installation of the connector 5 via the connecting rod 51. A connector 54 is embedded at the end of the connecting rod 51 facing the telescopic rod 23. The connecting rod 51 is installed at the end of the telescopic rod 23, and the connector 54 can connect with the connector 234. The electrical components in the cleaning head 5 can be connected to the circuit in the connecting seat 1 via the wires stored in the connector 234, connector 234, and clearance gap 24, thus powering the cleaning head 5 and enabling its normal operation. Specifically, the connector 234 can adopt a magnetic structure. The positions and shapes of the connectors 234 and 234 are mutually compatible, enabling electrical connection and thus powering the cleaning head 5 and its electrical components. The power supply and corresponding circuit components are installed in connector 1.

[0038] Reference Figure 2 and Figure 3 As shown, the outer diameter of the screw cylinder 22 is smaller than the inner diameter of the telescopic rod 23. Therefore, when the telescopic rod 23 is fitted onto the outer circumference of the screw cylinder 22, a clearance gap 24 is formed between them, which can be used to store wires. The screw cylinder 22 and the telescopic rod 23 are fixedly connected by bolts 25. Specifically, two connecting parts 221 are integrally connected to the end of the screw cylinder 22 near the connecting seat 1. The two connecting parts 221 are symmetrically arranged on the outer circumference of the screw cylinder 22. An annular boss 231 is provided on the outer circumference of the end of the telescopic rod 23 near the connecting seat 1. The connecting parts 221 and the annular boss 231 can abut against each other and are fixedly connected by bolts 25, so that the telescopic rod 23 and the screw cylinder 22 can move synchronously. When the drive motor 21 drives... When the screw 2 rotates, the screw barrel 22 and the telescopic rod 23 move together along the axis of the outer cylinder 4. An annular protrusion 41 is provided on the inner circumference of the end of the outer cylinder 4 away from the connecting seat 1, and an annular boss 231 is integrally connected to the end of the telescopic rod 23 near the connecting seat 1. The outer diameter of the annular boss 231 is smaller than the inner diameter of the outer cylinder 4, allowing both the telescopic rod 23 and the annular boss 231 to be fully embedded in the inner circumference of the outer cylinder 4. When the screw 2 is driven by the drive motor 21 to extend the telescopic rod 23, the annular boss 231 on the telescopic rod 23 can abut against and limit the movement of the annular protrusion on the inner circumference of the outer cylinder 4, preventing it from detaching and improving the reliability and stability of the cleaner.

[0039] Reference Figure 2 and Figure 4As shown, an annular boss 311 extends outward from one end of the tank 31 facing the connecting seat 1. The inner circumference of the annular boss 311 can be fitted onto the outer circumference of the connecting seat 1 to form a detachable installation structure, which facilitates the addition of cleaning fluid to the inside of the tank 31. A nozzle 32 is threadedly connected to the other end of the tank 31. The nozzle 32 communicates with the inside of the tank 31 and can draw up the cleaning fluid inside the tank 31 for spraying, which can assist the cleaning head 5 in cleaning work. The operation is convenient, simple and practical.

[0040] Reference Figure 4 and Figure 5 As shown, the lower end of the telescopic rod 23 extends downward and protrudes from the lower end of the outer cylinder 4, forming an annular boss 232.

A retaining spring 52 is embedded in the inner periphery of the connecting rod 51. One end of the retaining spring 52 abuts against the inner periphery of the connecting rod 51, and the other end is fixedly installed with a limiting block 53. The limiting block 53 can be embedded in the through hole opened on the outer periphery of the connecting rod 51. Under the elastic pressing action of the retaining spring 52, the limiting block 53 is firmly installed on the connecting rod 51 and protrudes from the outer periphery of the connecting rod 51. When the cleaning head 5 is connected to the telescopic rod 23 via the connecting rod 51... When making a fixed connection, the connecting rod 51 is fitted onto the inner circumference of the annular boss 232 until the end of the annular boss 232 abuts against the limiting block 53 on the outer circumference of the connecting rod 51. Then, the limiting block 53 is pressed down by hand, and the connecting rod 51 is pushed further into the inner circumference of the annular boss 232 until the limiting block 53 is embedded in the limiting hole 233 on the annular boss 232. Under the elastic pressing action of the snap ring 52, the telescopic rod 23 and the connecting rod 51 are locked together by the limiting block 53, forming a limited installation. When it is necessary to replace the cleaning head 5, the connecting rod 51 and the telescopic rod 23 can be separated by simply pressing down the limiting block 53 by hand. The installation and disassembly are convenient and highly practical.
