[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0018] like Figure 1-Figure 11 A door and window cleaning device shown in the figure comprises a rotating drum 1, six connecting frames 2 are arranged in an equidistant annular array on the outer surface of the rotating drum 1, a cleaning wipe 3 is clamped on the inner side of the connecting frame 2, a fixed shaft 4 is provided through the central axis of the rotating drum 1 to rotate with the fixed shaft 4, both ends of the fixed shaft 4 are connected to a gripping part, and a limiting mechanism is provided between one side of the rotating drum 1 and the fixed shaft 4; When the connection frame 2 contacts the door and window frame, it is pushed, and the adjacent cleaning wipes 3 are switched as the drum 1 rotates. The setting of six connection frames 2 can ensure that when the connection frame 2 contacts the door and window frame, the drum 1 can rotate sixty degrees to switch the cleaning wipes 3.

[0019] The gripping portion includes an outer frame 27 fixedly connected to both ends of the fixed shaft 4 and a gripping rod 30 rotatably connected to the rear surface of the outer frame 27, which is used for the user to grip.

[0020] like Figure 2 , Figure 3 , Figure 5 , Figure 8 , Fig. 9 As shown, the limiting mechanism includes six abutting blocks 7 slidably connected to one side of the drum 1, and a pushing block 5 fixedly sleeved on the outer surface of the fixed shaft 4. Six trapezoidal grooves 6 are provided on the surface of the pushing block 5. One end of the abutting block 7 abuts against the inner wall of the trapezoidal groove 6. A connecting shaft 28 is fixedly connected to one side of the pushing block 5. One end of the connecting shaft 28 is fixedly connected to the outer frame 27. A side connecting plate 11 is fixedly connected to the inner wall of the outer frame 27. A clamping mechanism is provided on one side of the side connecting plate 11 to clamp the end of the frontmost abutting block 7. A fixed plate 8 is fixedly connected to the side surface of the drum 1. A first guide rod 9 is fixedly provided on the inner side of the abutting block 7. The first guide rod 9 slides through the fixed plate 8. A first compression spring 10 is sleeved on the outer side of the first guide rod 9.

[0021] like Figure 4 , Figure 6 As shown, the clamping mechanism includes a fixing seat 25 fixedly connected to the side surface of the side connecting plate 11, and an arc-shaped strip 18 slidably clamped on the upper surface of the fixing seat 25 through an elastic mechanism. A collapsed opening 19 is provided on the upper surface of the arc-shaped strip 18, and a second inclined surface 20 is provided at the inner corner of the collapsed opening 19. A pushing head 21 is provided at the upper end of the arc-shaped strip 18. A clamping block 16 is elastically connected to the side surface of the side connecting plate 11. The clamping block 16 is clamped at the front end of the frontmost stop block 7. The front end of the clamping block 16 contacts the surface of the arc-shaped strip 18. A first inclined surface 17 is provided on the upper side of the clamping block 16. Even when the rebound speed of the arc-shaped strip 18 is too fast, after the stop block 7 contacts the first inclined surface 17, it can still be pushed so that the stop block 7 moves and slides into the inner side of the clamping block 16.

[0022] The elastic mechanism includes an arc groove 22 opened on the lower surface of the arc strip 18, an arc guide rod 23 fixedly arranged on the inner side of the arc groove 22, and a return spring 24 sleeved on the outer side of the arc guide rod 23. A guide block 26 is arranged on the upper surface of the fixed seat 25. The arc groove 22 and the guide block 26 are slidably matched. The arc guide rod 23 slides through the guide block 26. The sliding match between the guide block 26 and the arc groove 22 ensures the arc sliding trajectory of the arc strip 18.

[0023] like Figure 3 , Figure 4As shown, the side surface of the side connecting plate 11 is fixedly connected to the limiting frame 12, the side surface of the clamping block 16 is fixedly connected to the slide plate 13, the slide plate 13 slides and is clamped into the inner side of the limiting frame 12, the inner side of the limiting frame 12 is fixedly provided with a second guide rod 14, the slide plate 13 is slidably sleeved on the outer surface of the second guide rod 14, the outer side of the second guide rod 14 is sleeved with a second compression spring 15, the second compression spring 15 is located behind the slide plate 13, and the second compression spring 15 is used to drive the clamping block 16 to move.

[0024] like Fig.10 As shown, two connecting seats 29 are fixedly provided on the rear surface of the outer frame 27, the upper end of the gripping rod 30 is inserted between the two connecting seats 29, a through shaft 31 is passed through the sides of the two connecting seats 29, a sliding opening 35 is provided on the outer surface of the through shaft 31, a plug hole 36 is provided on the outer surface of the gripping rod 30, a sliding bar 37 is convexly provided on the inner wall of the plug hole 36, the sliding bar 37 is slidably inserted into the inner side of the sliding opening 35, the through shaft 31 is slidably inserted into the inner side of the plug hole 36, and a locking member is provided between the through shaft 31 and the connecting seat 29. The locking member includes a limiting plate 32 fixedly sleeved on the outer surface of the through shaft 31, a convex tooth 33 arranged in a ring array is convexly provided on the side of the limiting plate 32, a tooth groove 34 is provided on the side of one of the connecting seats 29, the convex tooth 33 is meshed with the tooth groove 34, a locking nut 38 with threaded matching is sleeved on the outer surface of the through shaft 31, and the locking nut 38 is tightly attached to the surface of the other connecting seat 29.

[0025] When in use, the drum 1 is dipped in water once, and the cleaning wipe 3 is used to clean the glass surface. When the cleaning wipe 3 on one side is used to a certain extent, it is necessary to replace the clean cleaning wipe 3, such as Fig.11 As shown, by pushing the rotating drum 1 upward, the pushing head 21 contacts the door and window frame, and the arc strip 18 will move downward. At this time, the collapsed mouth 19 faces the front of the block 16. Under the elastic force of the second compression spring 15, the slide plate 13 moves forward, and the block 16 is separated from the front end of the stop block 7. The rotating drum 1 continues to be pushed upward, and the connecting frame 2 contacts the door and window frame, which will push the connecting frame 2 to rotate. The stop block 7 pushes and moves after the inner wall of the trapezoidal groove 6, squeezing the first compression spring 10. After each connecting frame 2 rotates sixty degrees, the cleaning wipe 3 facing the glass is replaced. When the door and window frame no longer contacts the arc strip 18, under the elastic force of the reset spring 24, the arc strip 18 moves and resets. The second inclined surface 20 ensures that the block 16 can be pushed back to its original position. The block 16 will again clamp the end of the stop block 7 to achieve the purpose of locking, thereby preventing the rotating drum 1 from rotating when the glass is subsequently scrubbed.

[0026] By loosening the locking nut 38, the through shaft 31 can be pulled so that the limit plate 32 is no longer close to the connecting seat 29. After that, the through shaft 31 and the holding rod 30 can be rotated synchronously. When the angle between the holding rod 30 and the outer frame 27 is appropriate, the locking nut 38 is tightened so that the convex tooth 33 is snapped back to the inner side of the tooth groove 34 again, thereby preventing the holding rod 30 from rotating, thereby achieving the purpose of locking the angle, and being more flexible and convenient to use.
