Description

[Technical Field] This invention relates to the field of window cleaning machine technology, and more particularly to a highly stable window cleaning machine. [Background Technology] Window cleaning machines, as an automated cleaning device, not only improve the efficiency and quality of cleaning work, but also reduce labor intensity and safety risks. They are an indispensable assistant in modern cleaning work and can be widely used in residential, commercial buildings, public facilities and other fields, especially for places that are difficult to clean manually, such as glass curtain walls of high-rise buildings, skylights of large shopping malls, and glass roofs of exhibition halls.

[0001] However, existing window cleaning machines use a fixed mop structure or limited floating via simple springs, relying primarily on vacuum suction cups and fans for adsorption. The fixed mop structure struggles to adapt to the unevenness of glass surfaces, lacks self-adjusting capabilities, and cannot automatically optimize mop adhesion pressure, resulting in incomplete cleaning. Therefore, a highly stable window cleaning machine is needed. [Summary of the Invention] To address the aforementioned technical problems, this invention proposes a highly stable window cleaning machine.

[0002] This invention is achieved by the following technical solution: A highly stable window cleaning machine includes a window cleaning machine base and a window cleaning machine face shell. A control board for controlling the operation of the window cleaning machine and multiple fans controlled by the control board are provided between the window cleaning machine base and the window cleaning machine face shell. The window cleaning machine base is provided with cleaning components controlled by the control board to cooperate in completing the cleaning and multiple moving components for driving the window cleaning machine to move. The cleaning components include a first cleaning element disposed on the cleaning surface of the window cleaning machine base. The first cleaning element includes a mop that cooperates with the fans to adsorb and clean the window, and a floating plate disposed between the mop and the window cleaning machine base, which can adjust the mop to fit the window when the fans adsorb.

[0003] The floating plate is movably connected to the base of the window cleaning machine on one side, so that when encountering obstacles or complex curved surfaces while cleaning windows, the floating plate can adaptively adjust according to the unevenness of the cleaning surface. When the window surface is uneven, the floating plate can make the mop adhere better to the window and complete the cleaning work.

[0004] As described above, in the highly stable window cleaning machine, one side of the floating plate is movably connected to the base of the window cleaning machine, and the other side is fixedly connected to the mop, so that the floating plate can adaptively adjust according to the unevenness of the cleaning surface when encountering obstacles or complex curved surfaces while cleaning the window.

[0005] As described above, the highly stable window cleaning machine has multiple first openings on the mop corresponding to the air vents of the fan, and multiple second openings on the floating plate corresponding to the air vents of the fan.

[0006] As described above, the highly stable window cleaning machine has multiple hollow adjusting cylinders with alignment holes on the floating plate. The alignment holes are located at the bottom center of the adjusting cylinders, and the inner diameter of the alignment holes is smaller than the inner diameter of the adjusting cylinders. The base of the window cleaning machine has adjusting holes corresponding to the adjusting cylinders, and an alignment post located at the center of the adjusting holes corresponding to the alignment holes. Each floating plate can move independently.

[0007] As described above, the highly stable window cleaning machine has two second openings on each of the floating plates that correspond to the air vents of the fan.

[0008] As described above, the high-stability window cleaning machine includes a cleaning component comprising a second cleaning component controlled by the control panel and disposed on one side of the first cleaning component. The second cleaning component includes a roller brush disposed on one side of the window cleaning machine base perpendicular to the installation direction of the moving component, a fixed scraper disposed on one side of the roller brush, and a floating scraper controlled by the control panel and disposed on the other side of the same roller brush. The roller brush is rotatably disposed on the window cleaning machine base.

[0009] As described above, the high-stability window cleaning machine has a brush drive unit inside its base for controlling the movement of the brush. One side of the brush drive unit is electrically connected to the brush, and the other side is electrically connected to the control board, so that the brush can work under the program control of the control board.

[0010] As described above, the highly stable window cleaning machine has four fans between the base and the front shell of the window cleaning machine, and the four fans are arranged in a square array within the base of the window cleaning machine.

[0011] As described above, the high-stability window cleaning machine has a front-impact assembly for detecting obstacles on the side of the base of the window cleaning machine near each of the roller brushes. The front-impact assembly includes a front-impact body and detection devices disposed on both sides of the front-impact body. The detection device includes a hollow mounting cylinder and a detection element disposed inside the mounting cylinder for transmitting a signal to the control board when an obstacle signal is detected.

[0012] As described above, the high-stability window cleaning machine has two moving components on its base. The first cleaning component is located between the two moving components. Each floating plate is perpendicular to the installation direction of the moving component. Each moving component includes a set of moving wheels for driving the window cleaning machine and a moving drive component located inside the window cleaning machine base for controlling the movement of the moving wheels. The window cleaning machine base has a water tank and a spray plate connected to the water tank. The spray nozzles of the spray plate are close to the roller brush to keep the roller brush moist. The window cleaning machine base has an air duct assembly corresponding to the fan for forming an air cavity.

[0013] Compared with existing technologies, the high-stability window cleaning machine proposed in this invention has the following beneficial effects: 1. One side of the floating plate is movably connected to the base of the window cleaning machine so that when encountering obstacles or complex curved surfaces while cleaning windows, the floating plate can adaptively adjust according to the unevenness of the cleaning surface. When the window surface is uneven, the floating plate can make the mop better adhere to the window and complete the cleaning work. 2. Each of the floating plates can move independently. When the window cleaning machine faces an obstacle, the floating plates on one side can form a height difference structure with the floating plates on the other side, so that the window cleaning machine can maintain adhesion while overcoming the obstacle, thus ensuring the obstacle-overcoming ability of the window cleaning machine; in addition, the setting of multiple fans and the corresponding arrangement of each floating plate with two fans make the window cleaning machine have more stable performance during use, avoiding the impact of some fans 3 malfunctioning on the overall performance of the window cleaning machine; 3. The four fans can improve its adsorption and cleaning capabilities, and the four fans are arranged in a square array to ensure that the adsorption force generated by the fans is evenly distributed.

Detailed Implementation Methods

[0016] Specific embodiments, combined with Figures 1 to 10 As shown, further illustrating the technical solution of the present invention, a highly stable window cleaning machine includes a window cleaning machine base 1 and a window cleaning machine faceplate 2 that cooperates with it. A control board 13 for controlling the operation of the window cleaning machine and multiple fans 3 controlled by the control board 13 are provided between the window cleaning machine base 1 and the window cleaning machine faceplate 2. The window cleaning machine base 1 is equipped with a cleaning component 11 controlled by the control board 13 for cooperating in cleaning and multiple moving components 12 for moving the window cleaning machine. The cleaning component 11 and the moving components 12 are located on the side close to the surface to be cleaned. The fans 3, through the rotation of an internal motor, drive a fan to expel the air between the window cleaning machine and the window glass, forming a negative pressure zone, thereby generating suction force. Simultaneously, the cleaning component 11, under the action of the fans 3, can adhere tightly to the glass and remove stains.

[0017] In this embodiment, the cleaning component 11 includes a first cleaning component 111 disposed on the cleaning surface of the window cleaning machine base 1 and a second cleaning component 112 disposed on one side of the first cleaning component 111 and controlled by the control panel 13. The first cleaning component 111 includes a mop 1111 that works with the fan 3 to adsorb and clean the window, and a floating plate 1112 disposed between the mop 1111 and the window cleaning machine base 1, which can adjust the mop 1111 to fit the window when the fan 3 adsorbs. The second cleaning component 112 includes a roller brush 1121 disposed on one side of the window cleaning machine base 1 and perpendicular to the installation direction of the moving component 12, a fixed scraper 1122 disposed on one side of the roller brush 1121, and a floating scraper 1123 disposed on the other side of the same roller brush 1121 and controlled by the control panel 13. The roller brush 1121 is rotatably disposed on the window cleaning machine base 1.

[0018] When the window cleaning machine is working, one side of the floating plate 1112 is movably connected to the base 1 of the window cleaning machine, and the other side is fixedly connected to the mop 1111. This allows the floating plate 1112 to adaptively adjust to the unevenness of the cleaning surface when encountering obstacles or complex curved surfaces during window cleaning. With the action of multiple fans 3, it further ensures that the window cleaning machine can adhere to the window and complete the cleaning work. When the window surface is uneven, the floating plate 1112 can adaptively adjust, allowing the mop 1111 to better adhere to the window and complete the cleaning. Cleaning work; the roller brush 1121 can clean the window. Optionally, a second cleaning component 112 is provided on both sides of the first cleaning component 111. That is, two roller brushes 1121 and corresponding fixed scrapers 1122 and floating scrapers 1123 are arranged parallel on both sides of the window cleaning machine base 1. The second cleaning components 112 on both sides can work together to clean the window. The fixed scraper 1122 provides basic scraping ability, and the floating scraper 1123 can float and adjust its height to adjust the scraping force and angle, thus improving the cleaning effect.

[0019] Furthermore, as a preferred embodiment of this solution and not a limitation, the mop 1111 is provided with a plurality of first openings 1110 corresponding to the air outlets of the fan 3, and the float 1112 is provided with a plurality of second openings 41 corresponding to the air outlets of the fan 3. The float 1112 can achieve adaptive contact with the glass surface through movable settings. When the fan 3 generates negative pressure adsorption, the float 1112, through pressure distribution optimization design, enables the mop 1111 to obtain uniform contact pressure.

[0020] Furthermore, as a preferred embodiment of this solution and not a limitation, each of the floating plates 1112 is provided with two second openings 41 corresponding to the air vents of the fans 3. Optionally, the floating plates 1112 correspond to the mop 1111. Each floating plate 1112 can move independently, and when the window cleaning machine faces an obstacle, a height difference structure can be formed between the floating plates 1112 on one side and the floating plates 1112 on the other side, so that the window cleaning machine can maintain adhesion while overcoming obstacles, thus ensuring the obstacle-overcoming ability of the window cleaning machine. In addition, the arrangement of multiple fans 3 and the correspondence between each floating plate 1112 and two fans 3 make the window cleaning machine have more stable performance during use, avoiding the impact of some fans 3 malfunctioning on the overall performance of the window cleaning machine.

[0021] Furthermore, as a preferred embodiment of this solution and not a limitation, the floating plate 1112 is provided with a plurality of hollow adjusting cylinders 43 with alignment holes 42. The alignment holes 42 are located at the bottom center of the adjusting cylinders 43, and the inner diameter of the alignment holes 42 is smaller than the inner diameter of the adjusting cylinders 43. The window cleaning machine base 1 is provided with adjusting holes 18 corresponding to the adjusting cylinders 43, and alignment posts 19 located at the center of the adjusting holes 18 and corresponding to the alignment holes 42.

[0022] Optionally, four fans 3 are provided between the window cleaning machine base 1 and the window cleaning machine casing 2, and the four fans 3 are arranged in a square array within the window cleaning machine base 1. The four fans 3 can improve its adsorption and cleaning capabilities, and the square array arrangement of the four fans 3 ensures that the adsorption force generated by the fans 3 is evenly distributed.

[0023] Furthermore, as a preferred embodiment of this solution and not a limitation, the window cleaning machine base 1 is provided with a roller brush drive 14 for controlling the movement of the roller brush 1121. One side of the roller brush drive 14 is electrically connected to the roller brush 1121, and the other side is electrically connected to the control board 13, so that the roller brush 1121 can work under the program control of the control board 13.

[0024] In this embodiment, the window cleaning machine base 1 is provided with a front-impact assembly 5 for detecting obstacles on the side near each of the roller brushes 1121. The front-impact assembly 5 includes a front-impact body 51 and detection devices 52 disposed on both sides of the front-impact body 51. The detection device 52 includes a hollow mounting cylinder 521 and a detection element 522 disposed inside the mounting cylinder 521 for transmitting a signal to the control board 13 when an obstacle signal is detected. The detection element 522 can obtain a corresponding signal when cleaning the window glass or approaching an obstacle, and transmit the signal to the control board 13 so that the control board 13 can generate a signal and take corresponding actions, thereby achieving better cleaning of the window glass and providing convenience for the window cleaning machine to overcome obstacles.

[0025] Furthermore, as a preferred embodiment of this solution and not a limitation, the detection element 522 includes a detection probe 5221 and a connecting post 5222. The detection device 52 also includes a mating part 523 with an inner hole corresponding to the connecting post 5222. The connecting post 5222 is provided with an elastic spring 524 that mates with the mating part 523. The detection probe 5221 can be compressed and retracted into the mounting cylinder 521 under the action of an obstacle, and can also be reset by the action of the elastic spring 524, so as to better detect signals and provide a reference for the control board 13 to make actions.

[0026] Optionally, the floating scraper 1123 is located near the front impact assembly 5, and the fixed scraper 1122 is located away from the front impact assembly 5.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the window cleaning machine base 1 is provided with two moving components 12, and the first cleaning component 111 is disposed between the two moving components 12. Each floating plate 1112 is perpendicular to the installation direction of the moving component 12. The moving component 12 includes a set of moving wheels 121 for driving the window cleaning machine to move, and a moving drive component 122 disposed in the window cleaning machine base 1 for controlling the driving of the moving wheels 121. The moving wheels 121 can drive the window cleaning machine to move under the drive of the moving drive component 122, so as to cooperate with the fan 3 to achieve adsorption and movement on the window glass to complete the cleaning.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, the window cleaning machine base 1 is provided with a water tank 15 and a spray plate 16 connected to the water tank 15. The spray nozzles of the spray plate 16 are close to the roller brush 1121 to keep the roller brush 1121 moist.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the window cleaning machine base 1 is provided with an air duct assembly 17 corresponding to the fan 3 for forming an air cavity. The air duct assembly 17 corresponds to the plurality of fans 3 and can cooperate with the window cleaning machine housing 2 to form an airflow channel, while ensuring that the negative pressure generated by the plurality of fans 3 is evenly distributed on the bottom of the window cleaning machine base 1 and the glass contact surface.

[0030] The working principle of this embodiment is as follows: This invention proposes a highly stable window cleaning machine. It utilizes multiple fans 3 to generate suction force, and the floating plate 1112 is movably connected to the window cleaning machine base 1. During operation, this allows the mop 1111 to make better contact with the window. Its specific working principle is as follows: During operation, the moving component 12 drives the window cleaning machine to move. Simultaneously, under the control of the control panel 13, the roller brush 1121 and floating scraper 1123 can adapt to better clean the windows. Driven by the fan 3, the float 1112, through its optimized pressure distribution design, ensures that the mop 1111 receives uniform contact pressure and fits the window more closely to complete the cleaning. In addition, each float 1112 can move independently. When the window cleaning machine encounters an obstacle, it can form a height difference structure between the floats 1112 on one side and the floats 1112 on the other side, so that the window cleaning machine can maintain adhesion while overcoming obstacles, thus ensuring the window cleaning machine's obstacle-overcoming ability. At the same time, the setting of multiple fans 3 and the fact that each float 1112 corresponds to two fans 3 can make the window cleaning machine more stable during operation, and can prevent the window cleaning machine from being affected by the cessation of operation of some fans 3.
