[0031] See Figures 1-9This utility model provides an automatic window cleaner with a detachable and removable cleaning cloth, including a base and a handle 21 connected to the base. The base consists of a housing 7 and a wiping surface 16. A switch 1 is provided on the housing 7. A retractable clamping assembly is provided between the housing 7 and the wiping surface 16. The clamping assembly includes a set of retractable clamping plates 3 and sliding plates 2 that slide left and right to drive the clamping plates 3 to extend and retract. The clamping plates 3 are movably connected to both sides of the sliding plates 2. The sliding plates 2 are driven by the switch 1. Pressing the switch 1 can drive the sliding plates 2 to slide, thereby extending and retracting the clamping plates 3. Specifically, the bottom of the sliding plates 2 is provided with a first inclined groove 13 and a second inclined groove 14, and the bottom of the clamping plates 3 is provided with sliding posts 15. The sliding posts 15 respectively Insert the first inclined groove 13 and the second inclined groove 14, the sliding plate 2 slides left and right, and the sliding column 15 moves along the first inclined groove 13 and the second inclined groove 14 and drives the telescopic clamping plate 3 to extend and retract; in this embodiment, the outer edge of the housing 7 is provided with multiple protrusions, and the clamping plate 3 is provided with a relief groove adapted to the protrusions. When the clamping plate 3 extends, the protrusions exert downward pressure on the clamping plate 3, making it easier for the clamping plate 3 to grasp the wiping cloth. The bottom of the sliding plate 2 is provided with two first inclined grooves 13 and two second inclined grooves 14 on both sides. The first inclined grooves 13 and the second inclined grooves 14 are staggered. When the sliding plate 2 slides, it cooperates with the sliding column 15 through the first sliding groove group 13 and the second sliding groove group 14, thereby driving the clamping plate 3 to move.

[0032] In some embodiments, such as Figures 5-9As shown, the sliding plate 2 is provided with a driving inclined block 5, and the switch 1 is provided with an inclined surface 12 adapted to the driving inclined block 5. A return spring 6 is installed on the sliding plate 2. A locking hook 8 is also installed inside the housing 7. The sliding plate 2 is provided with a hook groove 4, and the hook groove 4 is provided with a second locking groove 11 for hooking the locking hook 8. When the return spring 6 is charged, the locking hook 8 is hooked on the second locking groove 11. Specifically, a pressure spring 9 is also installed inside the housing 7. The pressure spring 9 presses the locking hook 8 down into the groove 4. The groove 4 is provided with a first locking groove 10 and a second locking groove 11 that are connected in an annular shape. The locking hook 8 can circulate between the first locking groove 10 and the second locking groove 11. The driving block 5 is a triangular block. Since both the first locking groove 10 and the second locking groove 11 are V-shaped, their two ends are connected by vertical grooves. The hook groove forms a first triangular guide part 22 and a second triangular guide part 23 at the second locking groove 11. In use, pressing the switch 1 causes the sliding plate 2 to slide to one side, and the locking hook 8 enters the first triangular guide part 22 along the hook groove. Releasing the switch causes the locking hook 8 to engage with the second locking groove 11. Pressing the switch again causes the locking hook 8 to enter the second triangular guide part along the hook groove. 23. Release the switch, and the locking hook 8 is released; that is, when the switch 1 is pressed down, it pushes the drive block 5 to one side through the inclined surface 12. At this time, the sliding plate 2 moves, and the locking hook 8 moves from the first locking groove 10 along the side wall and enters the second locking groove 11, locking again and fixing the sliding plate 2 in the locked state. At this time, the clamping plate 3 retracts and locks, and the return spring 6 retracts. After pressing the switch 1 again, the locking hook 8 slides back to the first locking groove 10 along the vertical groove of the side wall under the push of the return spring 6, locking again. At this time, the clamping plate 3 unfolds to unlock the wiping cloth; wiping surface 16 Both sides of the clamping plate 3 are provided with first locking teeth 17, and the inner side of the clamping plate 3 is provided with second locking teeth 18. The housing 7 is provided with mounting base 19 and baffle 20. One end of locking hook 8 is inserted into mounting base 19. Locking hook 8 is provided with pressure spring 9. One end of return spring 6 abuts against baffle 20. The top of housing 7 is provided with circular boss. The bottom of handle 21 is provided with ring. The ring rotates and fits on the circular boss. The bottom of the ring is provided with protrusion. The housing 7 is provided with concave point corresponding to the protrusion, so that handle 21 can be rotated to make it easy to position. The center of the circular boss is provided with switch 1.

[0033] This utility model provides an automatic window cleaning device for disassembling and assembling cleaning cloths. A button is movably provided on the top of the housing, and the button is connected to a switch through a locking hook and a drive block. By pressing the button, the switch can be opened and unlocked, thereby working with the sliding plate to retract or open the clamping plates on both sides of the housing. This can achieve automatic unlocking and locking of the cleaning cloth, improving the efficiency of disassembling and assembling the cleaning cloth and eliminating the need for manual assembly.

[0034] The above description of the heating water pipe is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
