Description

Technical Field

[0001] This utility model relates to the field of window cleaning robot technology, and in particular to a window cleaning robot anti-leakage mechanism. Background Technology

[0002] With the improvement of living standards, window cleaning robots, as a type of smart home appliance, are gradually replacing manual cleaning. They use a built-in vacuum pump system to create negative pressure between the robot and the glass, allowing the robot to firmly adhere to the glass surface. The robot has two cleaning wheels equipped with cleaning cloths. One wheel is fixed to the glass by the negative pressure, while the other wheel rotates under the action of the drive system, generating torque and angular displacement to achieve the wiping function.

[0003] Currently, the existing window cleaning robots use a threaded connection between the suction cup and the suction pipe, but there is still a risk of slight air leakage, which can lead to reduced suction or even the robot falling off. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. By aligning the connecting ring on the suction cup with the suction pipe and sliding it upwards, the suction cup is rotated to bring the inner circular wall of the pull frame into contact with the screw. Then, the threaded ring is rotated, which drives the toothed ring to rotate. The toothed ring drives the three gears to rotate, which in turn drives the screw to rotate. The screw then moves the pull plate upwards. During this process, the screw, by contacting the circular groove, pulls the pull frame upwards. At the same time, the rubber ring on the connecting ring is pressed against the inner top wall of the mating ring, thus fixing the suction cup in place. This avoids the risk of slight air leakage caused by the threaded connection between the suction cup and the suction pipe, which could lead to reduced suction or even the suction cup falling off.

[0024] 2. By aligning the connecting grooves on the first and second protective plates with the connecting ring and sliding them in, and simultaneously engaging the locking plate with the elastic plate, the suction pipe is protected, preventing it from being easily impacted during daily use.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 4As shown, this utility model provides a technical solution: a window cleaning robot anti-leakage mechanism, including a window cleaning robot body 1 and a suction cup 2. Two suction pipes 5 are provided on the lower surface of the window cleaning robot body 1. A docking device 6 is provided on the arc surface of the suction pipes 5. The docking device 6 includes a threaded ring 601, which is threadedly connected to the arc surface of the suction pipes 5. A toothed ring 603 is fixedly connected to the lower surface of the threaded ring 601. A docking ring 612 is fixedly connected to the arc surface of the suction pipes 5 below the toothed ring 603. The arc surface of the docking ring 612 is uniformly shaped. Three positioning blocks 604 are fixedly connected, and each of the three positioning blocks 604 has a threaded screw 605 running through its inner wall. A pull plate 607 is fixedly connected to the bottom end of each screw 605, and a gear 606 is fixedly connected to the top end of each screw 605. The teeth of the gear 606 mesh with a gear ring 603. A connecting ring 609 is fixedly connected to the upper surface of the suction cup 2. Three pull frames 610 are evenly fixedly connected to the arc surface of the connecting ring 609. A circular groove 611 is formed on the bottom surface of the pull frame 610. The cross-sectional dimensions of the circular groove 611 are adapted to the cross-sectional dimensions of the pull plate 607, allowing the suction cup to... The connecting ring 609 on the disk 2 is aligned with the suction pipe 5 and slid upwards onto it. Then, the suction disk 2 is rotated to bring the inner annular wall of the pull frame 610 into contact with the screw 605. Next, the threaded ring 601 is rotated, which drives the gear ring 603 to rotate. The gear ring 603 drives the three gears 606 to rotate, which in turn drives the screw 605 to rotate. The screw 605 then drives the pull plate 607 to move upwards. During this process, the screw 605, by contacting the circular groove 611, pulls the pull frame 610 upwards, while simultaneously aligning the rubber ring 608 on the connecting ring 609 with the mating ring 61. The inner top walls of the suction cup 2 are pressed together to fix the suction cup 2 in place. A rubber ring 608 is fixedly connected to the top of the connecting ring 609. The rubber ring 608 abuts against the inner top wall of the docking ring 612 to improve airtightness. Several auxiliary balls 602 are evenly fixedly connected to the arc surface of the threaded ring 601 to increase the friction between the hand and the threaded ring 601 and prevent the hand from slipping. A silicone ring 3 is fixedly connected to the bottom of the suction cup 2 to ensure tight contact between the suction cup 2 and the glass. The suction pipe 5 and the threaded ring 601 are both made of stainless steel to prevent them from rusting and affecting normal use.

[0035] Reference Figures 5 to 6As shown in this embodiment: a protective device 4 is provided on the upper surface of the suction cup 2. The protective device 4 includes a connecting ring 403, a first protective plate 401, and a second protective plate 402. The connecting ring 403 is fixedly connected to the upper surface of the suction cup 2. The inner arc surfaces of the first protective plate 401 and the second protective plate 402 are provided with connecting grooves 404 corresponding to the positions of the connecting ring 403. The connecting grooves 404 are slidably connected to the connecting ring 403. By providing the protective device 4, the suction pipe 5 is protected from external impacts. Two clamping plates 405 are fixedly connected to the side of the first protective plate 401 near the second protective plate 402. The side of the second protective plate 402 is provided with an installation groove 406 corresponding to the position of the clamping plates 405. An elastic plate 407 is fixedly connected to the side wall of the installation groove 406. The elastic plate 407 is engaged with the clamping plates 405 to achieve the fixing effect between the first protective plate 401 and the second protective plate 402. The two clamping plates 405 are symmetrical and the force is evenly distributed, which improves the stability.

[0036] The working principle of the anti-leakage mechanism of the window cleaning robot provided by this utility model is as follows: In use, the connecting ring 609 on the suction cup 2 is aligned with the suction pipe 5 and slid upwards onto it. Then, the suction cup 2 is rotated to bring the inner annular wall of the pull frame 610 into contact with the screw 605. Next, the threaded ring 601 is rotated, causing the toothed ring 603 to rotate. The toothed ring 603 then drives the three gears 606 to rotate, which in turn drives the screw 605 to rotate. The screw 605 then moves the pull plate 607 upwards. During this process, the screw 605, by contacting the circular groove 611, pulls the pull frame 610 upwards, while simultaneously moving the rubber seal on the connecting ring 609 upwards. The rubber ring 608 presses against the inner top wall of the docking ring 612 to fix the suction cup 2 in place. This avoids the risk of slight air leakage caused by the threaded connection between the suction cup 2 and the suction pipe 5, which could lead to reduced suction or even the suction cup falling off. Since the suction pipe 5 is prone to impact during daily use, which could cause it to break or leak, it needs to be protected. First, the connecting grooves 404 on the first protective plate 401 and the second protective plate 402 are aligned with the connecting ring 403 and slid in. At the same time, the locking plate 405 is engaged with the elastic plate 407 to protect the suction pipe 5.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
