[0044] like Figures 1 to 6 As shown, this embodiment provides a window cleaning robot, comprising:

[0045] Body 1;

[0046] A walking device 2, arranged on the machine body 1, and used to drive the machine body 1 to walk;

[0047] A cleaning device 3, arranged on the machine body 1, for cleaning the surface to be cleaned;

[0048] A negative pressure device (not shown in the figure) is arranged on the machine body 1, and a negative pressure chamber 32 is arranged in the cleaning device 3. The negative pressure device pumps negative pressure into the negative pressure chamber 32 so that the window cleaning robot is adsorbed on the surface to be cleaned;

[0049] The body 1 is used to independently adjust the fit between the walking device 2 and the surface to be cleaned and / or independently adjust the fit between the cleaning device 3 and the surface to be cleaned to meet the use requirements of the window cleaning robot.

[0050] The body 1 of this embodiment can adjust the degree of contact between the walking device 2 and the surface to be cleaned and / or the cleaning device 3 and the surface to be cleaned, which helps to accurately control the pressure in the negative pressure chamber 32, and further helps to accurately adjust the suction force of the window cleaning robot on the surface to be cleaned. The window cleaning robot can make adaptive adjustments based on the material, smoothness and tilt angle of the surface to be cleaned, as well as the wind speed and vibration level of the working environment, thereby expanding the scope of application.

[0051] The body 1 of the present embodiment can adjust the degree of fit between the walking device 2 and the surface to be cleaned and / or the cleaning device 3 and the surface to be cleaned, which helps to accurately control the walking force output by the walking device 2 and / or the cleaning force output by the cleaning device 3, thereby helping to improve the movement stability, environmental adaptability and work efficiency of the window cleaning robot, as well as improve the cleaning effect and cleaning quality of the window cleaning robot.

[0052] Specifically, the cleaning device 3 generally includes cleaning parts such as cleaning cloth and disposable rag, and the walking device 2 generally includes structures such as rollers and turntables. Contact parts such as rubber are arranged on the surfaces of the rollers and turntables to generate a force between the surface to be cleaned. When the window cleaning robot is working, the negative pressure device draws negative pressure into the negative pressure chamber, so that the window cleaning robot generates an adsorption force and adsorbs on the surface to be cleaned; when the window cleaning robot adsorbs on the surface to be cleaned, the cleaning parts such as cleaning cloth and disposable rag of the cleaning device 3 contact the surface to be cleaned, and the contact parts such as rubber are arranged on the surfaces of the rollers and turntables of the walking device 2 contact the surface to be cleaned, and the cleaning device 3 and the walking device 2 jointly share the adsorption force generated by the window cleaning robot. It can be understood that the adsorption force generated by the window cleaning robot causes the cleaning device 3 and the walking device 2 to press on the surface to be cleaned, and generate a force with the surface to be cleaned. The force between the walking device 2 and the surface parts to be cleaned can drive the window cleaning robot to walk on the surface to be cleaned, and the force between the cleaning device 3 and the surface to be cleaned can clean the surface to be cleaned. When the cleaning device 3 and the walking device 2 are pressed against the surface to be cleaned, the tighter the cleaning device 3 is pressed, the smaller the gap between the cleaning cloth, disposable rag and other cleaning parts and the surface to be cleaned, and the higher the degree of fit between the cleaning device 3 and the surface to be cleaned; the tighter the walking device 2 is pressed, the deformation of the contact parts such as rubber increases the contact area between the walking device 2 and the surface to be cleaned, and the higher the degree of fit between the walking device 2 and the surface to be cleaned. It can be understood that the higher the degree of fit, the greater the force between the walking device and the surface to be cleaned. This embodiment independently adjusts the degree of fit between the walking device and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device and the surface to be cleaned to meet the use requirements of different forces. For example, when the surface to be cleaned is relatively dirty, it is necessary to increase the force between the cleaning device 2 and the surface to be cleaned to improve the cleaning effect.

[0053] like Figure 1-6 As shown, in one embodiment, the walking device 2 and the cleaning device 3 are arranged independently, and the body 1 is used to make one of the walking device 2 and the cleaning device 3 move relative to the other, and affect the degree of fit between the other and the surface to be cleaned. In this way, the degree of fit between the walking device 2 and the surface to be cleaned and / or the degree of fit between the cleaning device 3 and the surface to be cleaned can be independently adjusted to meet the use requirements of the window cleaning robot.

[0054] In this embodiment, a method is provided for independently adjusting the degree of contact between the walking device 2 and the surface to be cleaned and / or independently adjusting the degree of contact between the cleaning device 3 and the surface to be cleaned. When the degree of contact needs to be adjusted, one of the walking device 2 and the cleaning device 3 can be moved relative to the other. For example, if the walking device 2 moves in a direction away from the machine body 1, the cleaning device 3 moves in a direction away from the surface to be cleaned. In this way, the degree of contact between the walking device 2 and the surface to be cleaned is actively adjusted, and the degree of contact between the cleaning device 3 and the surface to be cleaned is affected. For another example, if the cleaning device 3 moves in a direction away from the machine body 1, the walking device 2 moves in a direction away from the surface to be cleaned. In this way, the degree of contact between the cleaning device 3 and the surface to be cleaned is actively adjusted, and the degree of contact between the walking device 2 and the surface to be cleaned is affected.

[0055] Specifically, the body 1 independently adjusts the walking device 2 so that the walking device 2 extends relative to the cleaning device 3, thereby reducing the airtightness of the negative pressure chamber 32 and the negative pressure in the negative pressure chamber 32, thereby reducing the adsorption force of the window cleaning robot, and reducing the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned.

[0056] Specifically, the body 1 independently adjusts the walking device 2 so that the walking device 2 retracts relative to the cleaning device 3, thereby increasing the airtightness of the negative pressure chamber 32 and the negative pressure in the negative pressure chamber 32, thereby increasing the adsorption force of the window cleaning robot, and increasing the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned.

[0057] This embodiment arranges the walking device 2 and the cleaning device 3 independently, which makes it convenient for the user and the window cleaning robot to independently control the positions and postures of the walking device 2 and the cleaning device 3, so as to adjust the degree of fit between the walking device 2 and the surface to be cleaned, and the degree of fit between the cleaning device 3 and the surface to be cleaned, thereby providing the user and the window cleaning robot with more operational freedom and enabling the window cleaning robot to adapt to more diverse cleaning tasks and environmental conditions.

[0058] like Figure 1-6 As shown, in one embodiment, the body 1 is configured to perform a first type of adjustment method, which includes: the body 1 independently adjusts the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adjust the degree of airtightness of the negative pressure chamber 32 to adapt to the use requirements of the window cleaning robot.

[0059] This embodiment adjusts the degree of airtightness of the negative pressure chamber 32 by adjusting the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device 3 and the surface to be cleaned, thereby achieving precise control of the adsorption force of the window cleaning robot, so that the window cleaning robot can adapt to surfaces to be cleaned with different materials, different smoothness and different inclination angles, ensuring that the window cleaning robot can maintain a stable adsorption state on various surfaces to be cleaned.

[0060] Secondly, the window-cleaning robot has the function of precisely controlling the adsorption force, which helps it adapt to complex working environments, such as strong winds, vibrations and other environmental interferences, and prevents the robot from falling off due to insufficient adsorption force, thereby enhancing the window-cleaning robot's ability to adapt to the environment. It also allows the window-cleaning robot to move and operate more stably on the surface to be cleaned, reducing the shaking caused by fluctuations in adsorption force and improving the stability of the window-cleaning robot.

[0061] Furthermore, the window cleaning robot can control the pneumatic noise generated by the window cleaning robot by adjusting the sealing degree of the negative pressure chamber 32, thereby reducing the noise level. Therefore, the window cleaning robot provided in this embodiment has the ability to adjust noise. Moreover, the window cleaning robot can reduce unnecessary energy consumption and improve energy efficiency by accurately controlling the adsorption force while ensuring the adsorption force.

[0062] like Figure 1-6 As shown, in one embodiment, when the machine body 1 performs the first type of adjustment, the negative pressure effect formed by the negative pressure device on the negative pressure chamber 32 is greater than the adjustment effect formed by the machine body adjusting the degree of fit between the walking device 2 and the surface to be cleaned and / or the degree of fit between the cleaning device 3 and the surface to be cleaned on the negative pressure chamber 32. The pressure in the negative pressure chamber 32 is finely adjusted by adjusting the degree of fit between the walking device 2 and the surface to be cleaned and / or the degree of fit between the cleaning device 3 and the surface to be cleaned to meet different usage requirements.

[0063] In this embodiment, when adjusting the degree of fit between the walking device 2 and the surface to be cleaned and / or the degree of fit between the cleaning device 3 and the surface to be cleaned, that is, when adjusting the movement of one of the walking device 2 and the cleaning device 3 relative to the other, the negative pressure in the negative pressure chamber 32 will be changed, and the negative pressure in the negative pressure chamber 32 will affect the overall adsorption force of the window cleaning robot, and adjusting the degree of fit between the walking device 2 and / or the cleaning device 3 and the surface to be cleaned will also affect the overall adsorption force of the window cleaning robot. In this process, the effect of the change in negative pressure in the negative pressure chamber 32 on the overall adsorption force of the window cleaning robot is greater than the effect of the fit on the overall adsorption force of the window cleaning robot.

[0064] like Figure 1-6As shown, in one embodiment, the first type of adjustment method includes: the body 1 independently adjusts the walking device 2, so that the walking device 2 extends relative to the cleaning device 3, the negative pressure in the negative pressure chamber 32 is reduced, and the degree of fit between the walking device 2 and the surface to be cleaned and the degree of fit between the cleaning device 3 and the surface to be cleaned are both reduced.

[0065] Specifically, the body 1 independently adjusts the walking device 2 so that the walking device 2 extends relative to the cleaning device 3, thereby reducing the airtightness of the negative pressure chamber 32 and the negative pressure in the negative pressure chamber 32, thereby reducing the adsorption force of the window cleaning robot, and reducing the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned.

[0066] In this embodiment, the body executes the first type of adjustment method, so that the fit degree between the walking device 2 and the surface to be cleaned and the fit degree between the cleaning device 3 and the surface to be cleaned are reduced, so as to reduce the friction between the walking device 2 and the cleaning device 3 and the surface to be cleaned, thereby reducing wear and extending the service life of the window cleaning robot.

[0067] At the same time, the reduction in the degree of fit enhances the flexibility of the window cleaning robot on certain complex or irregular surfaces to be cleaned (such as surfaces to be cleaned with borders, protrusions or decorations), making it easier for the window cleaning robot to adapt to these surfaces to be cleaned and improving the cleaning ability of the window cleaning robot on these surfaces to be cleaned.

[0068] like Figure 1-6 As shown, in one embodiment, the first type of adjustment method also includes: the machine body independently adjusts the walking device, so that the walking device is retracted relative to the cleaning device, the negative pressure in the negative pressure chamber is increased, and the degree of fit between the walking device and the surface to be cleaned and the degree of fit between the cleaning device and the surface to be cleaned are both increased.

[0069] Specifically, the body 1 independently adjusts the walking device 2 so that the walking device 2 retracts relative to the cleaning device 3, thereby increasing the airtightness of the negative pressure chamber 32 and the negative pressure in the negative pressure chamber 32, thereby increasing the adsorption force of the window cleaning robot, and increasing the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned.

[0070] In this embodiment, the body performs the first type of adjustment method, so that the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned are increased, so that the walking device 2 and the cleaning device 3 can be in closer contact with the surface to be cleaned, thereby achieving more comprehensive cleaning of the surface to be cleaned, reducing the risk of missing cleaning areas, helping to remove more stubborn stains and fine dust, and improving the cleaning effect.

[0071] At the same time, the degree of fit between the walking device 2 and the surface to be cleaned and the degree of fit between the cleaning device 3 and the surface to be cleaned are increased, which helps to improve the adsorption force, making the window cleaning robot more stable during work, and helps prevent accidents such as sliding or falling of the window cleaning robot during the wiping process, thereby improving safety of use.

[0072] In addition, the increase in the degree of fit between the walking device 2 and the surface to be cleaned and the increase in the degree of fit between the cleaning device 3 and the surface to be cleaned improves the cleaning effect and stability of the window cleaning robot, enables the window cleaning robot to complete the cleaning task faster, and improves the cleaning efficiency.

[0073] like Figure 1-6 As shown, in one embodiment, the first type of adjustment method also includes: the machine body 1 independently adjusts the walking device 2, so that when the walking device 2 is completely retracted relative to the cleaning device 3 and the walking device 2 is separated from the surface to be cleaned, the degree of fit between the cleaning device 3 and the surface to be cleaned reaches a maximum threshold range.

[0074] Specifically, the walking device 2 is completely retracted relative to the cleaning device 3, and the walking device 2 is separated from the surface to be cleaned. There is no force between the walking device 2 and the surface to be cleaned, and the window cleaning robot is no longer walking. The cleaning device 3 can clean the surface to be cleaned by its own rotation, so as to meet the requirement that the window cleaning robot needs to be in a fixed-point cleaning state. This embodiment enables the cleaning device 3 to have a fixed-point deep cleaning function, so that the window cleaning robot can perform targeted deep cleaning on a specific area without moving, thereby saving time for walking and repositioning. At the same time, the contact area between the cleaning device 3 and the surface to be cleaned is increased, and the cleaning ability of the cleaning device 3 is enhanced by covering a large area of ​​the surface to be cleaned, thereby improving the cleaning effect.

[0075] The degree of fit between the cleaning device 3 and the surface to be cleaned reaches the maximum threshold range, which means that when the working power of the negative pressure device does not change, the cleaning device 3 completely shares the adsorption force of the window cleaning robot, and the degree of fit between the cleaning device 3 and the surface to be cleaned reaches the maximum threshold range.

[0076] like Figure 1-6 As shown, in one embodiment, the body 1 is also configured to execute a second type of adjustment method, which includes: when the negative pressure value of the negative pressure chamber 32 is maintained within a preset range, the body 1 independently adjusts the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device 3 and the surface to be cleaned to adapt to the use requirements of the window cleaning robot.

[0077] Specifically, when the negative pressure value of the negative pressure chamber 32 is maintained within a preset range, it means that the output power of the negative pressure device can be adjusted so that the negative pressure value of the negative pressure chamber 32 is not affected by changes in the sealing degree of the negative pressure chamber.

[0078] Under the premise of ensuring that the adsorption force generated in the negative pressure chamber 32 is constant, this embodiment adjusts the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adjust the walking force output by the walking device 2 and the cleaning force output by the cleaning device 3 to meet the requirements of stable walking and / or high cleaning ability of the window cleaning robot.

[0079] like Figure 1-6 As shown, in one embodiment, the second type of adjustment method includes: the body 1 adjusts the walking device 2 and the cleaning device 3 to adjust and allocate the degree of fit between the walking device 2 and the surface to be cleaned, as well as the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adapt to the use requirements of the window cleaning robot.

[0080] This embodiment enables the window cleaning robot to adjust and allocate the degree of fit between the walking device 2 and the surface to be cleaned, and the degree of fit between the cleaning device 3 and the surface to be cleaned, according to the use requirements of the window cleaning robot, so that the degree of fit between the walking device 2 and the surface to be cleaned, and the degree of fit between the cleaning device 3 and the surface to be cleaned match the surface to be cleaned, which helps to improve cleaning efficiency, enhance cleaning effects and reduce energy consumption. The specific allocation principle is: when the window cleaning robot is adsorbed on the surface to be cleaned, the walking device 2 and the cleaning device 3 share the adsorption force together. Under the condition of a certain adsorption force, the closer to the surface to be cleaned, the greater the shared adsorption force. For example, at the beginning, the walking device 2 and the cleaning device 3 share the same proportion of the total adsorption force. When the walking device 2 moves in the direction away from the body 1, the cleaning device 3 is pushed up, and the cleaning device 3 moves in the direction away from the surface to be cleaned. At this time, the adsorption force shared by the walking device 2 increases, the degree of fit of the walking device 2 increases, the adsorption force shared by the cleaning device 3 decreases, the degree of fit of the cleaning device 3 decreases, and the action force between the walking device 2 and the surface to be cleaned increases. At this time, it is more conducive to the walking of the window cleaning robot and can adapt to the walking needs of the window cleaning robot; when the walking device 2 moves in the direction close to the body 1, the cleaning device 3 moves in the direction close to the surface to be cleaned. At this time, the adsorption force shared by the walking device 2 decreases, the degree of fit of the walking device 2 decreases, the adsorption force shared by the cleaning device 3 increases, the degree of fit of the cleaning device 3 increases, and the action force between the cleaning device 3 and the surface to be cleaned increases, which is more conducive to cleaning needs.

[0081] like Figure 1-6 As shown, in one embodiment, the second type of adjustment method includes: the body 1 adjusts the walking device 2 and the cleaning device 3 so that the degree of fit between the walking device 2 and the surface to be cleaned is greater than or equal to the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adapt to the walking requirements of the window cleaning robot.

[0082] In this embodiment, the degree of fit between the walking device 2 and the surface to be cleaned is greater than or equal to the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adapt to large and relatively smooth surfaces to be cleaned (such as large glass windows in modern buildings), so that the walking device provides higher stability and stronger grip, ensuring that the window cleaning robot will not slip or deviate from the path during the wiping process.

[0083] At the same time, increasing the fit between the walking device 2 and the surface to be cleaned, that is, increasing the contact area between the walking device and the surface to be cleaned, helps to reduce the resistance during slipping and movement, thereby improving the walking efficiency, so as to meet the needs of quickly completing cleaning tasks or covering a large area of ​​windows in a limited time.

[0084] In addition, increasing the degree of fit between the walking device 2 and the surface to be cleaned, that is, increasing the contact area between the walking device and the surface to be cleaned, can provide better support and balance, so that the window cleaning robot can walk and clean stably, and enable the window cleaning robot to adapt to the use needs of cleaning on surfaces to be cleaned with some special shapes (such as arc, inclined, etc.).

[0085] like Figure 1-6 As shown, in one embodiment, the second type of adjustment method also includes: the body 1 adjusts the walking device 2 and the cleaning device 3, so that the degree of fit between the walking device 2 and the surface to be cleaned is adjusted to be smaller than the degree of fit between the cleaning device 3 and the surface to be cleaned, so as to adapt to the cleaning needs of the window cleaning robot.

[0086] In this embodiment, the degree of fit between the walking device 2 and the surface to be cleaned is smaller than the degree of fit between the cleaning device 3 and the surface to be cleaned, thereby improving the cleaning fineness and cleaning efficiency of the window cleaning robot to meet the use requirements of high cleaning precision, and can clean the surface to be cleaned with stubborn stains, water stains or fingerprints.

[0087] Moreover, the degree of fit between the walking device 2 and the surface to be cleaned is less than the degree of fit between the cleaning device 3 and the surface to be cleaned, which helps the window cleaning robot to adapt to the shape of the window more flexibly and adapt to the use requirements of cleaning areas with small areas or complex shapes (such as arcs, polygons, etc.); at the same time, the contact area of ​​the cleaning device is larger, so that the window cleaning robot can better cover the surface to be cleaned, so as to perform more detailed wiping, reduce missed areas, and achieve comprehensive cleaning.

[0088] like Figure 1-6 As shown, in one embodiment, the machine body 1 is used to adjust the walking device 2 and the cleaning device 3 when recognizing that the current cleaning environment of the surface to be cleaned is fast cleaning, so that the degree of contact between the walking device 2 and the surface to be cleaned and the degree of contact between the cleaning device 3 and the surface to be cleaned are reduced;

[0089] The machine body 1 is also used to adjust the walking device 2 and the cleaning device 3 when it is identified that the current cleaning environment of the surface to be cleaned is enhanced cleaning, so that the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned are increased.

[0090] The window cleaning robot of this embodiment can make adaptive adjustments based on the current cleaning environment of the surface to be cleaned, so that the window cleaning robot can adapt to various complex cleaning environments and perform targeted cleaning based on the current cleaning environment of the surface to be cleaned. It has wide applicability and meets the needs of different users.

[0091] At the same time, the cleaning efficiency in the fast-cleaning area is improved to avoid excessive cleaning and waste of time and energy; the cleaning effect in the enhanced-cleaning area is improved to avoid dirt residue.

[0092] Also, in the fast cleaning area, the degree of contact between the walking device 2 and the surface to be cleaned and the degree of contact between the cleaning device 3 and the surface to be cleaned are reduced to reduce the cleaning force and avoid excessive wiping that may cause damage or scratches on the surface to be cleaned.

[0093] In one embodiment, the body 1 is used to identify that the current cleaning environment of the surface to be cleaned is quick cleaning when the rotation speed of the walking device 2 is greater than a preset rotation speed (the surface to be cleaned has low dirtiness and low friction), so that the degree of fit between the walking device 2 and the surface to be cleaned and the degree of fit between the cleaning device 3 and the surface to be cleaned are reduced, so as to reduce the airtightness and adsorption force of the negative pressure chamber 32, increase the walking force between the walking device 2 and the surface to be cleaned, reduce the cleaning force between the cleaning device 3 and the surface to be cleaned, and increase the walking speed of the walking device 2.

[0094] The body 1 is also used to identify the current cleaning environment of the surface to be cleaned when the rotation speed of the walking device 2 is less than the preset rotation speed (the dirt level of the surface to be cleaned is low and the friction is high), so as to enhance cleaning, increase the fit between the walking device 2 and the surface to be cleaned and the fit between the cleaning device 3 and the surface to be cleaned, so as to increase the airtightness and adsorption force of the negative pressure chamber 32, reduce the walking force between the walking device 2 and the surface to be cleaned, increase the cleaning force between the cleaning device 3 and the surface to be cleaned, improve the cleaning ability of the cleaning device 3, and reduce the walking speed of the walking device 2.

[0095] This embodiment recognizes the current cleaning environment of the surface to be cleaned by real-time monitoring of the rotation speed of the walking device 2, and the recognition result has a high accuracy rate; and there is no need to wait for the processing of other complex signals, and the timeliness is strong.

[0096] In one embodiment, the body 1 has a control unit, and a detection device is arranged on the body 1. The detection device and the control unit are signal-connected, and the detection device is used to detect the rotation speed of the walking device 2 and output a speed signal; the control unit is used to independently adjust the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjust the degree of fit between the cleaning device 3 and the surface to be cleaned according to the speed signal, so as to adjust the degree of airtightness of the negative pressure chamber 32, and thereby adjust the force between the cleaning device 3 and the surface to be cleaned and the force between the walking device 2 and the surface to be cleaned.

[0097] Specifically, the detection device is a rotation speed sensor.

[0098] Specifically, the control unit is a microprocessor.

[0099] like Figure 3 and Figure 5 As shown, in one embodiment, an adjusting device 4 is provided on the body, and the body 1 independently adjusts the degree of fit between the walking device 2 and the surface to be cleaned and / or independently adjusts the degree of fit between the cleaning device 3 and the surface to be cleaned through the adjusting device 4 to adapt to the use requirements of the window cleaning robot.

[0100] Specifically, the adjusting device 4 is used to adjust the distance between the walking device 2 and the machine body 1 to enable the walking device 2 to move relative to the cleaning device 3; and / or, the adjusting device 4 is used to adjust the distance between the cleaning device 3 and the machine body 1 to enable the cleaning device 3 to move relative to the walking device 2.

[0101] This embodiment allows the window cleaning robot to adjust the distance between the walking device 2 and the body 1 and / or the distance between the cleaning device 3 and the body 1 according to usage requirements by providing an adjustment device 4, thereby achieving fine control over the degree of fit of the walking end 21 of the walking device and the degree of fit of the cleaning end 31 of the cleaning device.

[0102] In one embodiment, the adjusting device 4 includes a driving member 41 and a transmission member 42 connected to each other, and the driving member 41 is disposed on the machine body 1. In one embodiment, the transmission member 42 is connected to the walking device 2, and the transmission member 42 is configured to be driven by the driving member 41 to drive the walking device 2 to approach or move away from the machine body 1. In one embodiment, the transmission member 42 is connected to the cleaning device 3, and the transmission member 42 is configured to be driven by the driving member 41 to drive the cleaning device 3 to approach or move away from the machine body 1.

[0103] Specifically, the transmission member 42 is arranged longitudinally relative to the surface to be cleaned, the output shaft of the driving member 41 is arranged transversely relative to the surface to be cleaned, a gear 43 is arranged on the output shaft of the driving member 41, and the driving member 41 is used to drive the gear 43 to perform a rotary motion; a rack 44 is arranged on the transmission member 42, and the rack 44 meshes with the gear 43 to convert the rotary motion into a linear motion. This embodiment helps to reduce the longitudinal volume of the window cleaning robot.

[0104] Specifically, the driving member 41 is a motor, but is not limited thereto.

[0105] like Figure 1-6 As shown, in one embodiment, the walking device 2 is inclined relative to the cleaning device 3, and the machine body 1 is used to independently adjust the contact area between the walking device 2 and the surface to be cleaned, so as to adjust the degree of contact between the walking device 2 and the surface to be cleaned.

[0106] In this embodiment, the contact area between the walking device 2 and the surface to be cleaned can be changed by adjusting the inclination of the walking device 2, so as to independently adjust the fit between the walking device 2 and the surface to be cleaned to adapt to different surfaces to be cleaned.

[0107] like Figure 6 As shown, in one embodiment, an abutment 5 is provided at one end of the walking device 2 that contacts the surface to be cleaned, and the abutment 5 is used to change the type of force when the walking device 2 contacts the surface to be cleaned. Specifically, the abutment 5 is a rolling member, so as to change the sliding friction force generated when the walking device 2 contacts the surface to be cleaned into rolling friction force. The walking device 2 of this embodiment contacts the surface to be cleaned through the rolling member, which reduces the direct contact area between the walking device 2 and the surface to be cleaned, thereby reducing friction resistance, reducing energy loss, and improving travel efficiency.

[0108] Specifically, the abutment member 5 is a roller or a universal wheel, but is not limited thereto.

[0109] In one embodiment, there are multiple abutment members 5 , and the multiple abutment members 5 are arranged in a ring array relative to the central axis of the walking device 2 .
