Description

Technical Field

[0001] This utility model relates to the technical field of window cleaning machines, specifically a walking adsorption mechanism for a window cleaning machine. Background Technology

[0002] Window cleaning machines, also known as automatic window cleaners, smart window cleaners, or intelligent window wipers, are a type of smart home appliance that effectively solves the problems of cleaning windows in high-rise buildings and outdoors. Window cleaning machines typically use the force of their adhesive attachment to the glass to move a cloth at the bottom of the machine to wipe away dirt and grime. They are suitable for various window sizes, including those in homes, offices, and commercial buildings.

[0003] The existing walking suction structure design of window cleaning machines mainly takes two forms:

[0004] 1. The motor drives the track wheels, which in turn drive the tracks to move. The fan draws air from the enclosed area between the window cleaning machine and the cleaning surface to create negative pressure, causing the window cleaning machine to adhere to the cleaning surface.

[0005] 2. The motor-driven rotating mechanism moves the two suction cups of the cleaning cloth alternately. The fan draws air from the enclosed area between the window cleaning machine and the cleaning surface to create negative pressure, causing the window cleaning machine to adhere to the cleaning surface.

[0006] In the first method, the window cleaning machine tends to slide down due to gravity during horizontal cleaning, and both methods result in the machine falling over due to insufficient fan suction. Therefore, there is an urgent need to provide a walking suction mechanism for window cleaning machines to overcome the shortcomings in current practical applications. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1-5 This utility model provides a window cleaning machine walking and adsorption mechanism, which includes:

[0035] Bottom shell 100;

[0036] Track wheel 110, the track wheel 110 is rotatably mounted on the bottom shell 100, and the bottom shell 100 is also provided with a drive assembly for driving the track wheel 110 to rotate.

[0037] The suction cup track 111 is mounted on the track wheel 110;

[0038] And a take-off rod mechanism 120 for separating the suction cup track 111 from the suction surface;

[0039] The track wheels 110 are symmetrically arranged on the bottom shell 100 from left to right;

[0040] The machine-retrieving top rod mechanism 120 is located in the middle position between the left and right sets of track wheels 110, and the machine-retrieving top rod mechanism 120 is located at the end of the suction cup track 111;

[0041] The lifting rod mechanism 120 includes:

[0042] Dental box 121, the dental box 121 is disposed on the bottom shell 100, and the dental box 121 is equipped with a dental box cover 125;

[0043] The machine removal rod 127 is disposed inside the tooth box 121, and the tooth box 121 is also provided with a screw mechanism for driving the machine removal rod 127 closer to or away from the adsorption surface.

[0044] And a drive unit for driving the screw mechanism.

[0045] In this embodiment of the invention, the track wheel 110 is driven by a drive assembly, which in turn drives the suction cup track 111 to rotate, enabling the window cleaning machine to move. The suction cups on the track simultaneously adhere to the cleaning surface, preventing the window cleaning machine from sliding down or falling off. The screw mechanism drives the lifting rod 127 to extend towards the adsorption surface, increasing the distance between the front end of the window cleaning machine and the adsorption surface. At the same time, the left and right track wheels 110 drive the suction cup track 111 to move towards the lifting rod, and the suction cups on the track detach from the adsorption surface one by one, realizing the window cleaning machine lifting function and solving the problem that the suction force is too strong after adding the track and suction cups, making it difficult to lift the window cleaning machine from the adsorption surface.

[0046] In one embodiment of this utility model, please refer to Figures 1-5 The drive assembly includes a motor and a gearbox, the gearbox being used for power transmission between the output shaft of the motor and the track wheel 110.

[0047] In this embodiment, the track wheel 110 is driven by a motor and a gearbox, wherein the motor and gearbox can adopt existing publicly available technologies.

[0048] In one embodiment of this utility model, please refer to Figures 1-5 The dental box 121 and the dental box cover 125 are detachably connected by screws;

[0049] The tooth box 121 and the bottom shell 100 are detachably connected by screws;

[0050] The drive unit includes a primary gear 122, a secondary gear 123 and a tertiary gear 124 for driving the screw mechanism, which are disposed in the gearbox 121. The secondary gear 123 meshes with the primary gear 122 and the tertiary gear 124 respectively, and a motor 126 for driving the primary gear 122 to rotate is also disposed on the gearbox cover 125.

[0051] In this embodiment, the window cleaning machine can be equipped with a retrieval button for controlling the working state of the motor 126. The retrieval push rod mechanism 120 is located in front of the middle of the left and right track wheels 110 on the bottom shell 100. After the window cleaning machine finishes working and returns to its original position, the retrieval button on the window cleaning machine is pressed. At this time, the fan on the window cleaning machine stops working; the motor 126 starts, and the movement is transmitted to the third gear 124 through the first-stage gear 122 and the second-stage gear 123 in the push rod lifting gear box 121. The third-stage gear mechanism 124 drives the retrieval push rod 127 to extend towards the suction surface through the screw mechanism, increasing the distance between the front end of the window cleaning machine and the suction surface; at the same time, the left and right track wheels 110 drive the suction cup track 111 to move towards the retrieval push rod, and the suction cups on the track detach from the suction surface one by one, realizing the retrieval function of the window cleaning machine and solving the problem that the suction force is too large after the track is added with suction cups, making it difficult to remove the window cleaning machine from the suction surface.
