They free people from tedious housework, fulfilling their desire to improve their living environment and quality of life. Intelligent and efficient window cleaning robots are increasingly favored by users.

[0003] Currently, window cleaning robots often leave particulate stains when cleaning glass surfaces. These particulate stains can easily be caught in the cleaning mechanism, causing scratches on the glass. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the technical solution adopted in this application is to propose a window cleaning robot.

[0005] A window cleaning robot includes: Host; The walking mechanism is used to propel the window cleaning robot forward. At least one first cleaning mechanism is installed on the main unit to clean stains in a preset area in front of the main unit's forward path; At least one second cleaning mechanism is installed on the main unit to perform a second cleaning operation on the area that has been cleaned by the first cleaning mechanism; The first cleaning mechanism includes a first scraping mechanism located at the first end of the main unit; When the walking mechanism drives the host in the first direction, the first scraping mechanism is switched to the scraping state for scraping away stains. And, when the walking mechanism drives the host in the second direction, the first scraping mechanism is switched to the disengaged state to stop scraping.

[0006] In an optional embodiment, the first cleaning mechanism further includes a second scraping mechanism located at the second end of the main unit; The first end and the second end are the two ends in the forward path direction of the host; When the walking mechanism drives the host in the first direction, one of the first and second scraping mechanisms located in front of the host's forward path switches to the scraping state, and the other switches to the disengagement state.

[0007] In an optional embodiment, the first cleaning mechanism further includes a second scraping mechanism located at the second end of the main unit; The first end and the second end are the two ends in the forward path direction of the host; When the walking mechanism drives the host in the first direction, both the first scraping mechanism and the second scraping mechanism switch to the scraping state. And, when the walking mechanism drives the host in the second direction, both the first scraping mechanism and the second scraping mechanism switch to the disengaged state.

[0008] In an optional embodiment, the window cleaning robot is further provided with a motion transmission structure; The motion transmission structure is used to transmit the walking motion to the first cleaning mechanism when the window cleaning robot is walking, so that when the walking mechanism drives the main unit in the first direction, it drives the first cleaning mechanism to switch to the scraping state. And, when the walking mechanism drives the host in the second direction, it causes the first cleaning mechanism to switch to the disengaged state.

[0009] In an optional embodiment, the motion transmission structure is a passive structure, and when the window cleaning robot is running, the walking mechanism moves in the opposite direction to the motion transmission structure.

[0010] In an optional embodiment, the motion transmission structure includes: The system comprises a first transmission structure, a second transmission structure, and a third transmission structure. The first transmission structure is used to contact the surface to be cleaned. The first, second, and third transmission structures are connected in sequence. The third transmission structure is connected to the first cleaning mechanism. The first transmission structure is used to transmit the operation of the window cleaning robot to the third transmission structure through the second transmission structure, and the transmission power directions of the first and third transmission structures are the same.

[0011] In an optional embodiment, the motion transmission structure is connected to the walking mechanism to transmit the walking power of the walking mechanism to the first cleaning mechanism.

[0012] In an optional embodiment, the window cleaning robot is also equipped with a water spraying mechanism; The water spraying mechanism is installed on the main unit to spray and soften stains in a preset area in front of the main unit's forward path.

[0013] In an optional embodiment, the window cleaning robot is also equipped with a recycling mechanism; The recovery mechanism includes an air outlet, a negative pressure device, a recovery flow channel, and an air intake nozzle; The negative pressure device is located in the recovery channel to generate airflow; The air outlet, the recovery channel, and the air intake are interconnected to form a gas flow path from the air intake through the recovery channel, and the extension direction of the air intake is directed towards the first cleaning mechanism to recover the dirt scraped by the first cleaning mechanism and to use airflow to blow heat away the main unit. The recycling channel and / or the air intake are also provided with a filter screen for intercepting dirt.

[0014] In an optional embodiment, the first cleaning mechanism includes at least one of a side brush, a rubber strip, and a flexible scraper.

[0015] In an optional embodiment, the second cleaning mechanism is movably connected to the host via a movable mechanism for controlling the second cleaning mechanism to switch between a cleaning state and a stopped cleaning state. After the first cleaning mechanism cleans the preset area, the movable mechanism controls the second cleaning mechanism to switch to the cleaning state.

[0016] Beneficial effects: This application provides a window cleaning robot that reduces the probability of scratching the glass surface during operation, improves the cleaning effect, and optimizes the user experience. Specifically, the window cleaning robot is equipped with at least one first cleaning mechanism to clean stains in a preset area in front of the main unit's forward path. The window cleaning robot is also equipped with at least one second cleaning mechanism to clean the area cleaned by the first cleaning mechanism. The first cleaning mechanism performs preliminary cleaning of the preset area before the second cleaning mechanism, which is a pre-cleaning operation. This largely removes particulate stains in the preset area, reducing the probability of scratching the glass surface during the second cleaning mechanism's cleaning, thereby solving the problem of glass scratches during cleaning. Furthermore, the combined cleaning action of the initial cleaning by the first cleaning unit and the subsequent cleaning by the second cleaning unit effectively enhances the cleaning performance of the window cleaning robot.

[0027] See Figures 1 to 3 As shown in the figure, a window cleaning robot provided in this application embodiment includes: a main unit 1, a walking mechanism 2, a first cleaning mechanism 3 and a second cleaning mechanism 4; Walking mechanism 2 is used to drive the window cleaning robot to move; For example, the driving mode of the walking mechanism 2 can be wheel drive, track drive or wheel-track hybrid drive.

[0028] Specifically, in some embodiments of this application, the walking mechanism 2 adopts tracked drive or wheel-tracked hybrid drive. The walking mechanism 2 includes at least two main wheels and a track that meshes with the main wheels for transmission. With the cooperation of the main wheels and the track, the window cleaning robot is driven to move.

[0029] Of course, there are no specific restrictions on the drive type of the walking mechanism 2, as long as it can drive the window cleaning robot to move.

[0030] At least one first cleaning mechanism 3 is installed on the main unit 1 to clean stains in a preset area in front of the main unit 1's forward path; For example, the first cleaning mechanism 3 can clean stains in the preset area by using a prying cleaning method, such as sweeping away stains in the preset area by swinging the first cleaning mechanism 3 back and forth, specifically using a combination structure of gears, racks and pinions; it can also use a scraping cleaning method, such as scraping the stains away from the preset area by the first cleaning mechanism 3 adhering to the preset area; or it can use a pushing cleaning method, such as pushing away or scraping away stains in the preset area by the first cleaning mechanism 3, specifically using a linear drive mechanism such as a cylinder or push rod.

[0031] Of course, the above content is only some examples of the cleaning methods of the first cleaning unit 3, and no specific restrictions are made on the cleaning methods of the first cleaning unit 3.

[0032] Understandably, the first cleaning mechanism 3 cleans stains in a preset area in front of the main unit 1's forward path, and has different effects on different types of stains: On the one hand, for particulate stains, the first cleaning mechanism 3 can remove the particulate stains from the preset area in the main unit 1's forward path, thereby reducing the impact of particulate stains on the second cleaning mechanism 4 and largely avoiding the problem of scratches on the glass surface caused by particulate stains being rolled into the bottom of the second cleaning mechanism 4; on the other hand, for soluble stains, the cleaning by the first cleaning mechanism 3, such as pushing or turning, can promote the mixing of soluble stains with water or cleaning solution, improve the degree of dissolution or removal of stains, and with the movement of the first cleaning mechanism 3, it can also remove some soluble stains, making it easier for the second cleaning mechanism 4 to clean further.

[0033] At least one second cleaning mechanism 4 is installed on the main unit 1 to perform a second cleaning operation on the area that has been cleaned by the first cleaning mechanism 3.

[0034] Specifically, in some embodiments of this application, the second cleaning mechanism 4 may be a wiping structure made of rubber or silicone, and a cleaning cloth may be fitted onto the wiping structure. Thus, the second cleaning mechanism 4 can perform a wiping operation on the preset area. Of course, there are no specific limitations on the specific structure and material selection of the second cleaning mechanism 4, as long as it meets the cleaning requirements of the window.

[0035] Understandably, the first cleaning mechanism 3 can remove particulate stains within a preset area, while the second cleaning mechanism 4 can further clean the area after cleaning by the first cleaning mechanism 3, thus largely preventing scratches from particulate stains on the glass surface. The first cleaning mechanism 3 and the second cleaning mechanism 4 work together and complement each other in their cleaning functions. The first cleaning mechanism 3 can directly remove particulate stains that are difficult for the second cleaning mechanism 4 to remove, and accelerates the dissolution of soluble stains and / or improves the degree of peeling of soluble stains, improving the cleaning environment of the second cleaning mechanism 4 and facilitating further cleaning. The second cleaning mechanism 4 is used to wipe away peeled substances, absorb wastewater, and complete the secondary cleaning of the preset area, improving its cleanliness. The first cleaning mechanism 3 and the second cleaning mechanism 4 can be made of different materials. The first cleaning mechanism can use relatively rigid materials such as scrapers or hard-bristled brushes, which are characterized by strong physical scraping and peeling capabilities, and are particularly adept at removing particulate stains, dried residues, or stubborn solid impurities attached to the surface. This design allows it to quickly remove large particles during the initial cleaning stage, reducing the burden on the second cleaning mechanism 4 and creating conditions for subsequent deep cleaning. The second cleaning mechanism 4 can use soft absorbent materials such as cloths, fleece cloths, or microfiber cloths. These materials offer advantages in terms of dirt-holding capacity, water retention, and delicate wiping performance, effectively absorbing fine dust, liquid stains, and oily residue remaining after the first cleaning step. This combination of "hard and soft, scraping and suction" not only improves cleaning efficiency and thoroughness but also addresses different types of stains, protecting the integrity and smoothness of the surface to be cleaned. The dual cleaning achieved through the cooperation of the first cleaning mechanism 3 and the second cleaning mechanism 4 significantly optimizes the cleaning effect of the window cleaning robot.

[0036] In an optional embodiment, such as Figures 6 to 9 As shown, the first cleaning mechanism 3 includes a first scraping mechanism 31 located at the first end of the main unit 1; When the walking mechanism 2 drives the host 1 in the first direction, the first scraping mechanism 31 is switched to the scraping state for scraping stains. And, when the walking mechanism 2 drives the host 1 in the second direction, the first scraping mechanism 31 is switched to the disengaged state to stop scraping.

[0037] For example, the first scraping mechanism 31 can be raised and lowered and / or extended and retracted along the height direction of the host 1, and / or can be rotated along its own circumferential direction.

[0038] Of course, no specific restrictions are placed on the state switching method of the first sweeping mechanism 31.

[0039] For example again, Figures 6 to 9The direction of the directional mark in the diagram is the direction of movement of the host 1 under the drive of the walking mechanism 2. The walking mechanism 2 drives the host 1 along the first direction, which can be clockwise, so that the host 1 moves forward. At this time, the first scraping mechanism 31 switches to the scraping state. The walking mechanism 2 drives the host 1 along the second direction, which can be counterclockwise, so that the host 1 moves backward. At this time, the first scraping mechanism 31 switches to the disengagement state.

[0040] Of course, there are no restrictions on the specific driving direction of the walking mechanism 2 and the corresponding movement direction of the host machine 1.

[0041] Understandably, the scraping state of the first scraping mechanism 31 is the state of contacting the glass surface and cleaning the stained glass surface; the detachment state of the first scraping mechanism 31 is the state of detaching from the glass surface and suspending above the glass surface.

[0042] The first scraping mechanism 31 can switch between scraping and detachment states according to the movement direction of the main unit 1, better adapting to the changes in the working state of the window cleaning robot. For example, when the window cleaning robot takes the direction of the first end where the first scraping mechanism 31 is located as its traveling direction, the first scraping mechanism 31 automatically switches to the scraping state, which can clean the preset area in front of the window cleaning robot's forward path, reducing the risk of scratching the glass surface due to particulate stains and optimizing the cleaning effect of the window cleaning robot.

[0043] If the window cleaning robot needs to clean an area that has already been cleaned by the first cleaning mechanism 3 and / or the second cleaning mechanism 4, the robot can travel in the direction of its second end. In this case, the first scraping mechanism 31 automatically switches to a disengaged state. The robot can then use only the second cleaning mechanism 4 to clean the glass surface, effectively preventing the first cleaning mechanism 3 from carrying away dirt and causing secondary contamination of the freshly cleaned area, thus improving the cleaning effect. The first and second ends are in opposite directions.

[0044] More specifically, in an optional embodiment, combined with Figure 1 , Figure 2 , Figure 3 , Figures 6 to 11 As shown, the first cleaning mechanism 3 also includes a second scraping mechanism 32 located at the second end of the main unit 1; The first end and the second end are the two ends in the forward path direction of host 1; Specifically, such as Figure 6 and Figure 7 As shown, when the walking mechanism 2 drives the host 1 along the first direction, one of the first scraping mechanism 31 and the second scraping mechanism 32 located in front of the host 1's forward path switches to the scraping state, and the other switches to the disengagement state.

[0045] Specifically, in some embodiments of this application, the first direction can be either clockwise or counterclockwise. When the walking mechanism 2 drives the host 1 along the first direction, and the window cleaning robot moves along the forward path, if the first scraping mechanism 31 is located in front of the host 1 and the second scraping mechanism 32 is located behind the host 1, then the first scraping mechanism 31 switches to the scraping state and the second scraping mechanism 32 switches to the disengaged state; if the second scraping mechanism 32 is located in front of the host 1 and the first scraping mechanism 31 is located behind the host 1, then the second scraping mechanism 32 switches to the scraping state and the first scraping mechanism 31 switches to the disengaged state.

[0046] Understandably, the first cleaning mechanism 3 includes a first scraping mechanism 31 and a second scraping mechanism 32, with the first scraping mechanism 31 located at the first end of the main unit 1 and the second scraping mechanism 32 located at the second end of the main unit 1. This ensures that whether the window cleaning robot moves forward or backward, there is at least one first cleaning mechanism 3 located in front of the main unit 1 that performs preliminary cleaning on the area to be cleaned by the second cleaning mechanism 4. This prevents particulate dirt from being rolled into the bottom of the second cleaning mechanism 4, reducing the risk of scratching the glass. It also reduces the accumulation of particulate dirt, slows down the rate at which the surface of the second cleaning mechanism 4 becomes saturated with dirt, reduces scratches, and improves cleanliness. Furthermore, the first cleaning mechanism 3 located at the rear of the main unit 1 will switch to a disengaged state, reducing wear on the first cleaning mechanism 3 located at the rear of the main unit 1 and reducing the movement resistance of the window cleaning robot, thereby saving energy consumption and extending the battery life of the window cleaning robot.

[0047] In an optional embodiment, the first cleaning mechanism 3 further includes a second scraping mechanism 32 located at the second end of the main unit 1; The first end and the second end are the two ends in the forward path direction of host 1; Specifically, such as Figure 8 and Figure 9 As shown, when the walking mechanism 2 drives the host 1 in the first direction, both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to the scraping state. And, when the walking mechanism 2 drives the host 1 in the second direction, both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to the disengaged state.

[0048] Specifically, in some embodiments of this application, the first direction can be clockwise, and the second direction is counterclockwise, such as... Figure 8 As shown, when the walking mechanism 2 drives the main unit 1 along the first direction, the first scraping mechanism 31 located at the first end of the window cleaning robot and the second scraping mechanism 32 located at the second end of the window cleaning robot both switch to the scraping state; as Figure 9As shown, when the walking mechanism 2 drives the host 1 along the second direction, the first scraping mechanism 31 located at the first end of the window cleaning robot and the second scraping mechanism 32 located at the second end of the window cleaning robot are both switched to the disengaged state.

[0049] Understandably, the first scraping mechanism 31 and the second scraping mechanism 32 are in the same state. Only when the walking mechanism 2 drives the window cleaning robot to move in a preset direction will the first scraping mechanism 31 and the second scraping mechanism 32 switch to the scraping state.

[0050] When both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to scraping mode, the first scraping mechanism 31, located in front of the main unit 1's forward path, can perform the aforementioned functions of cleaning particulate stains, accelerating the dissolution and removal of soluble stains, and improving the cleanliness of the glass surface. The second cleaning mechanism 4 is still used to perform wiping and other re-cleaning operations on the area cleaned by the first scraping mechanism 31. The second scraping mechanism 32 is used to perform the final cleaning operation on the area cleaned by the second cleaning mechanism 4. The second scraping mechanism 32 can handle the traces left by the second cleaning mechanism 4, such as fine water marks or traces of water on the edges. Through the scraping of the second scraping mechanism 32, the gloss of the window glass surface is effectively improved. This achieves effective synergy between the first scraping mechanism 31, the second cleaning mechanism 4, and the second scraping mechanism 32, significantly optimizing the cleaning effect of the window cleaning robot.

[0051] When both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to the disengaged state, neither the first scraping mechanism 31 nor the second scraping mechanism 32 will contact the glass surface. The glass surface will be wiped and cleaned only by the second cleaning mechanism 4. This can effectively reduce the resistance during the operation of the window cleaning robot, making the movement of the window cleaning robot more stable, reducing energy consumption, and thus extending the battery life of the window cleaning robot.

[0052] Understandably, when the walking mechanism 2 drives the window cleaning robot in different directions, it can adapt to different application scenarios and meet diverse application needs in practical applications. When both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to the scraping state, they can be used in the initial cleaning process of the glass surface to avoid scratching the glass with particulate stains; when both the first scraping mechanism 31 and the second scraping mechanism 32 are switched to the disengaged state, they can be used after the initial cleaning of the glass surface, such as for applications that require repeated wiping and cleaning of the glass surface or wiping away water stains.

[0053] Both the first sweeping mechanism 31 and the second sweeping mechanism 32 can switch states via a motor or other drive device, and a main control unit is further configured to control the state switching between the walking mechanism 2 and the first cleaning mechanism 3.

[0054] The shape of a robotic vacuum cleaner can be square, rectangular, disc-shaped, elliptical, etc. It has an outer shell with an installation cavity inside. Other structural components can be installed in the installation cavity, such as a water spray mechanism, main control unit, negative pressure device, drive device, etc., including but not limited to these.

[0055] The main control unit can be a device that controls the window cleaning robot to complete certain actions or tasks according to instructions. Optionally, the main control unit may include a control circuit board, which is electrically connected to the walking mechanism 2. The walking mechanism 2 is used to drive the main unit 1, and the control circuit board can send control commands to the walking mechanism 2. The walking mechanism 2 controls the movement of the window cleaning robot according to the received control commands. Similarly, the main control unit can also control the state switching of the first cleaning mechanism 3.

[0056] Exemplarily, in an optional embodiment, such as Figures 1 to 11 As shown, the window cleaning robot is also equipped with a motion transmission structure 5; The motion transmission structure 5 is used to transmit the walking motion to the first cleaning mechanism 3 when the window cleaning robot is walking, so that when the walking mechanism 2 drives the host 1 in the first direction, it drives the first cleaning mechanism 3 to switch to the scraping state. When the walking mechanism 2 drives the host 1 in the second direction, it drives the first cleaning mechanism 3 to switch to the disengaged state.

[0057] Understandably, the motion transmission structure 5 transmits the driving force generated by the window cleaning robot during its movement to the first cleaning mechanism 3. This allows the first cleaning mechanism 3 to adaptively switch between the scraping and detaching states based on the direction of the window cleaning robot's movement. On one hand, the window cleaning robot does not require an additional drive unit for the first cleaning mechanism 3, reducing manufacturing costs and facilitating a compact design. On the other hand, the motion transmission structure 5 enables effective linkage between the first cleaning mechanism 3 and the walking mechanism 2, improving the response speed to the window cleaning robot's movement. It eliminates the need for separate control of the first cleaning mechanism 3's state switching by the main control unit, reducing control complexity and allowing for real-time adaptation to the window cleaning robot's movement state, automatically adjusting accordingly.

[0058] In an optional embodiment, the motion transmission structure 5 is a passive structure, and when the window cleaning robot is running, the walking mechanism 2 moves in the opposite direction to the motion transmission structure 5.

[0059] Understandably, the motion transmission structure 5 is a passive structure. For example, it uses the friction between the window cleaning robot and the glass surface during its movement as a power source to drive the switching of the first cleaning mechanism 3. This simplifies the overall structure of the window cleaning robot, reduces manufacturing costs, and reduces the number of parts that need to be controlled and coordinated. Consequently, it reduces the complexity of the system and reduces potential failure points. Moreover, the simple structure of the motion transmission structure 5 helps to achieve a compact and miniaturized design of the window cleaning robot to meet the cleaning needs of narrow areas such as window corners and optimize the cleaning effect. At the same time, it can also reduce the drive and control energy consumption required for additional drive devices, which can extend the battery life of the window cleaning robot. Furthermore, it enhances the coordination between the walking mechanism 2, the motion transmission structure 5, and the first cleaning mechanism 3 to improve the smoothness and stability of the window cleaning robot's cleaning operation.

[0060] In addition, this passive transmission method can reduce the impact of the motion transmission structure 5 and the first cleaning mechanism 3 on the movement of the walking mechanism 2. When the first cleaning mechanism 3 switches to the scraping state, it contacts the glass surface and stops the motion transmission structure 5, but does not have a significant impact on the drive of the walking mechanism 2.

[0061] More specifically, such as Figures 4 to 7 As shown, the motion transmission structure 5 includes: The first transmission structure 51, the second transmission structure 52, and the third transmission structure 53 are connected in sequence. The first transmission structure 51 is used to contact the surface to be cleaned. The first transmission structure 51, the second transmission structure 52, and the third transmission structure 53 are connected to the first cleaning mechanism 3 in sequence. The first transmission structure 51 is used to transmit the operation of the window cleaning robot to the third transmission structure 53 through the second transmission structure 52, and the transmission power direction of the first transmission structure 51 and the third transmission structure 53 is the same, while the driving direction of the walking mechanism 2 is opposite to the movement direction of the motion transmission structure 5.

[0062] For example, the first transmission structure 51 can be a combination of a driven wheel and a track. When the main unit 1 moves, the first transmission structure 51 rotates clockwise or counterclockwise under the action of friction after contacting the glass surface. The second transmission structure 52 can be a drive wheel that meshes with the first transmission structure 51, transmits the power of the first transmission structure 51, and rotates in the opposite direction to the first transmission structure 51. The third transmission structure 53 meshes with the second transmission structure 52 and is connected to the first cleaning mechanism 3 so as to drive the first cleaning mechanism 3 to move in the same direction as the rotation direction of the first transmission structure 51.

[0063] In another optional embodiment, the motion transmission structure 5 is connected to the walking mechanism 2 to transmit the walking power of the walking mechanism 2 to the first cleaning mechanism 3. That is, the motion transmission structure 5 is an active structure, and the motion transmission structure 5 moves in the same direction as the walking mechanism 2.

[0064] For example, the motion transmission structure 5 can be selected from one of the following: a gear transmission structure, a belt transmission structure, or a linkage structure. Of course, there are no restrictions on the specific implementation structure of the motion transmission structure 5.

[0065] More specifically, the connection between the motion transmission structure 5 and the walking mechanism 2 can be disconnected. After the first cleaning mechanism 3 completes its state switch, the connection between the motion transmission structure 5 and the walking mechanism 2 can be disconnected through the control of the main control unit, thereby avoiding any impact on the drive of the walking mechanism 2.

[0066] Understandably, the motion transmission structure 5 is connected to the walking mechanism 2, directly transmitting power from the walking mechanism 2 to the first cleaning mechanism 3. This simplifies the overall structure of the robot, eliminating the need for an additional drive unit for the first cleaning mechanism 3 and helping to reduce manufacturing costs to some extent. The motion transmission structure 5 can directly utilize walking power, further reducing overall energy consumption. Furthermore, the connection between the motion transmission structure 5 and the walking mechanism 2 helps to achieve a natural match between the cleaning actions of the first cleaning mechanism 3 and the movement of the window cleaning robot. When the walking mechanism 2 drives the window cleaning robot forward in a predetermined direction, the motion transmission structure 5 can trigger the first cleaning mechanism 3 to switch to the scraping state; when the window cleaning robot changes direction, the motion transmission structure 5 can trigger the first cleaning mechanism 3 to switch to the disengagement state, thereby reducing control latency and ensuring the smoothness of the window cleaning robot's cleaning process to some extent.

[0067] In an optional embodiment, such as Figure 11 As shown, the window cleaning robot is also equipped with a water spraying mechanism 6; The water spray mechanism 6 is installed on the main unit 1 to spray and soften the stains in the preset area in front of the main unit 1's forward path.

[0068] The first cleaning mechanism 3 is used to clean stains that have been sprayed and softened by the water spraying mechanism 6 in a preset area in front of the main unit 1's forward path.

[0069] For example, the water spraying mechanism 6 can be used to spray clean water or cleaning liquid, and the water spraying mechanism 6 has multiple spraying modes, and the corresponding spraying mode can be called according to the external environment information; the clean water or cleaning liquid can also be heated by setting a heating mechanism to optimize the cleaning effect.

[0070] Understandably, the water spraying mechanism 6 is used to soften the stains in the preset area in front of the main unit 1 before the first cleaning mechanism 3 cleans the preset area. This helps to improve the removal rate of particulate stains by the first cleaning mechanism 3, and also helps to improve the degree or speed of stain removal, thereby improving the cleaning ability of the window cleaning robot and effectively improving the cleaning efficiency and cleaning effect of the window cleaning robot.

[0071] In an optional embodiment, combined with Figure 10 and Figure 11 As shown, the window cleaning robot is also equipped with a recycling mechanism, which is used to collect the stains cleaned by the first cleaning mechanism 3. The dotted line in the figure shows the approximate location of the recycling mechanism.

[0072] Specifically, in some embodiments of this application, the recovery mechanism includes an air outlet 71, a negative pressure device 72, a recovery channel 73, and an air intake 74; The negative pressure device 72 is located in the recovery channel 73 and is used to generate airflow; The air outlet 71, the recovery channel 73 and the air inlet 74 are connected to each other to form a gas flow path from the air inlet 74 through the recovery channel 73, and the extension direction of the air inlet 74 is directed towards the first cleaning mechanism 3 to recover the dirt scraped by the first cleaning mechanism 3 and to use the airflow to blow heat off the main unit 1. A filter 75 for intercepting dirt is also provided at the recovery channel 73 and / or the air intake 74.

[0073] More specifically, in some embodiments of this application, the recycling mechanism is further provided with a dust collection bin 76, which is detachably connected to the recycling channel 73 and positioned close to the filter screen 75 to contain dirt particles intercepted by the filter screen 75. Of course, there are no specific limitations on the exact location of the dust collection bin 76; it only needs to fulfill the function of dirt recycling.

[0074] The pore size of the filter screen 75 can be set according to the particle size of the dirt. For example, glass fiber filter media can be selected. The dust collection bin 76 can be set at the bottom of the recovery channel 73 and connected to the recovery channel 73. After the dirt is intercepted by the filter screen 75, the dirt can be used to fall naturally into the dust collection bin 76 by gravity.

[0075] For example, the negative pressure device 72 can be a vacuum pump or a fan. By driving the continuous operation of the negative pressure device 72 to generate airflow, suction is created to collect the stains. Of course, there are no limitations on the specific implementation structure of the negative pressure device 72.

[0076] Understandably, the recycling mechanism serves several purposes. First, it collects particulate matter and dirt scraped by the first cleaning mechanism 3, preventing the dirt from falling off again during the movement of the main unit 1. This helps maintain the cleanliness of the glass surface and avoids scratching it. Second, the recycling channel 73 can be located close to a heat source inside the main unit 1, such as the main control unit or the walking mechanism 2. After the filter 75 intercepts the dirt, the airflow still needs to pass through the inside of the main unit 1 before flowing out from the air outlet 71, achieving heat exchange with the heat source or dissipating heat by blowing air onto the heat source. This improves the heat dissipation of the window cleaning robot, effectively extending its service life and optimizing its performance. Third, the negative pressure device 72 generates airflow, which helps accelerate the movement speed of the airflow on the glass surface, thereby accelerating the evaporation of water on the glass surface, reducing water stains or marks, and optimizing the brightness and cleanliness of the glass surface after cleaning.

[0077] In an optional embodiment, the first cleaning mechanism 3 includes at least one of a side brush, a rubber strip, and a flexible scraper.

[0078] Of course, no restrictions are placed on the specific structure of the first cleaning mechanism 3.

[0079] Specifically, in some embodiments of this application, such as Figure 11 As shown, the first cleaning mechanism 3 is provided with an abutment part 30 on the side away from the main unit 1. The abutment part 30 is used to contact and abut the receiving surface when the first cleaning mechanism 3 is in the scraping state.

[0080] For example, the abutting part 30 may be a strip-shaped structure arranged along the length direction of the first cleaning mechanism 3 and arranged at an angle to the main body of the first cleaning mechanism 3, so as to serve as the contact part between the first cleaning mechanism 3 and the glass surface, thereby enhancing the stability of the contact between the first cleaning mechanism 3 and the glass surface during the movement of the window cleaning robot, thereby obtaining a good stain removal effect.

[0081] More specifically, in some embodiments of this application, the cross-sectional shape of the first cleaning mechanism 3 is V-shaped.

[0082] For example, the cross-sectional shape of the first cleaning mechanism 3 can be V-shaped. When the opening of the V-shaped structure faces the host 1, the first cleaning mechanism 3 can push away the stains from the left and right sides of the forward path to reduce the stains on the forward path. When the pointed part of the V-shaped structure faces the host 1, the first cleaning mechanism 3 can collect the stains on the forward path, which is convenient for the subsequent recycling mechanism to recycle.

[0083] The first cleaning mechanism 3 has a larger cleanable area than the second cleaning mechanism 4.

[0084] In an optional embodiment, the second cleaning mechanism 4 is movably connected to the main unit 1 via a movable mechanism (not shown in the figure) for controlling the second cleaning mechanism 4 to switch between a cleaning state and a stopped cleaning state. After the first cleaning mechanism 3 cleans the preset area, the movable mechanism controls the second cleaning mechanism 4 to switch to the cleaning state.

[0085] For example, the movable mechanism can be a cylinder, push rod, or motor, etc., and there is no limitation on the specific structure of the movable mechanism. The movable mechanism is used to extend the second cleaning mechanism 4 away from the main unit 1 or retract it towards the main unit 1, so as to control the second cleaning mechanism 4 to switch between a cleaning state and a stopped cleaning state. When the second cleaning mechanism 4 is in the stopped cleaning state, the second cleaning mechanism 4 is suspended and does not contact the glass surface. When the second cleaning mechanism 4 is in the cleaning state, the second cleaning mechanism 4 contacts and is used to wipe the glass surface.

[0086] Understandably, the movable mechanism is designed to meet the practical needs of window cleaning. When cleaning begins, the first cleaning mechanism 3 has not yet cleaned the preset area. If the second cleaning mechanism 4 operates simultaneously with the first cleaning mechanism 3, there is still a risk of scratching the glass. The movable mechanism controls the second cleaning mechanism 4 to switch to a stopped cleaning state. Once the first cleaning mechanism 3 has cleaned a certain preset area, the movable mechanism controls the second cleaning mechanism 4 to switch back to the cleaning state, thus avoiding the risk of glass scratches and meeting the needs of practical applications.

[0087] The embodiments of this application have at least the following beneficial effects: This application provides a window cleaning robot that reduces the probability of scratching the glass surface during operation, improves the cleaning effect, and optimizes the user experience. Specifically, the window cleaning robot is equipped with at least one first cleaning mechanism 3, which cleans stains in a preset area in front of the main unit 1's forward path. The window cleaning robot is also equipped with at least one second cleaning mechanism 4, which cleans the area after being cleaned by the first cleaning mechanism 3. The first cleaning mechanism 3 performs preliminary cleaning of the preset area before the second cleaning mechanism 4, which is a pre-cleaning operation. This largely removes particulate stains in the preset area, reducing the probability of the second cleaning mechanism 4 scratching the glass surface during cleaning, thereby solving the problem of glass scratches during cleaning. Furthermore, the combined cleaning of the initial cleaning by the first cleaning mechanism 3 and the secondary cleaning by the second cleaning mechanism 4 effectively improves the cleaning effect of the window cleaning robot.
