Description

Technical Field

[0001] The present application relates to the field of intelligent cleaning, and particularly relates to a window cleaning robot base, a window cleaning robot, and a window cleaning robot system. Background Art

[0002] With the continuous improvement of modern living standards, people's requirements for the quality of life are also getting higher and higher. Automated and intelligent devices are increasingly widely used in daily life. In recent years, in particular, intelligent devices have emerged continuously. For example, some intelligent floor cleaning robots or intelligent window cleaning robots, etc. On the one hand, these intelligent robots can perform a large amount of cleaning work in a short time, saving people a lot of time; on the other hand, these intelligent devices can free people from tedious housework, so these intelligent devices are also becoming more and more popular.

[0003] A new type of robot represented by the intelligent window cleaning robot has emerged continuously. The intelligent window cleaning robot can not only help people clean the indoor glass, but also complete some high-difficulty outdoor high-altitude operations.

[0004] When the intelligent window cleaning robot is performing cleaning work, it continuously moves on the glass through the traveling wheels, and uses the rag installed at the bottom of the window cleaning robot to wipe and clean the glass. However, after working for a period of time, the traveling wheels of the window cleaning robot will be stained with dust or other debris on the glass, which will cause the surface friction of the traveling wheels to decrease, resulting in the window cleaning robot slipping and unable to be used normally. Therefore, the traveling wheels need to be cleaned at regular intervals. At present, the dust or debris stained on the traveling wheels of the window cleaning robot is mainly cleaned manually, which is likely to cause a bad experience for users.

[0005] Secondly, before the intelligent window cleaning robot starts working, it is necessary to wet the rag at the bottom of the window cleaning robot. For this, the existing window cleaning robots mainly wet the rag for window cleaning manually by spraying water or cleaning liquid before cleaning. However, whether the water content of the rag for window cleaning of the window cleaning robot is too much or too little will affect the normal operation of the window cleaning robot. If the water content of the rag for window cleaning of the window cleaning robot is too much, when the window cleaning robot is working due to gravity, too much water will enter the cabin of the window cleaning robot, causing the traveling wheels at the bottom of the window cleaning robot to slip and the window cleaning robot unable to operate normally; if the water content of the rag for window cleaning of the window cleaning robot is too little, when the window cleaning robot is running, the rag for window cleaning of the window cleaning robot will float on the glass surface due to insufficient humidity and cannot effectively clean the glass.

[0006] In addition, before each use of the intelligent window cleaning robot, the accessories of the window cleaning robot need to be taken out of the packing box one by one, and then put back into the packing box one by one after use, which obviously adds cumbersome work to the user. Moreover, as a robot powered by electricity, it needs to be charged at regular intervals. Obviously, the use process of the window cleaning robot is rather cumbersome. Summary of the Invention

Detailed implementation manners

[0049] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementations disclosed below.

[0050] The present application provides a window cleaning robot base, a window cleaning robot, and a window cleaning robot system. The following are specific embodiments.

[0051] As Figure 1 shown, the window cleaning robot base includes: a base body 101, a traveling wheel cleaning part 102, and a charging part 103.

[0052] As Figure 2As shown, it is a schematic diagram of the peripheral structure and internal section of the base of the window cleaning robot. The base body 101 includes a base upper cover 104, a base lower cover 105, and a base rear cover 106.

[0053] The specific structure and working principle of the base of the automatic window cleaning robot are described below.

[0054] As Figure 1 and Figure 3 shown, the charging member 103 is disposed on the base body 101. The base body 101 has an L-shaped structure. The recessed space of the L-shaped structure is a space for placing the window cleaning robot 200. When the window cleaning robot 200 is placed at the docking position of the base body 101, for example, when the window cleaning robot 200 is placed at the charging position on the base body 101, that is, when the window cleaning robot 200 is placed at the charging position in the recessed space of the base body 101, the base body 101 can dock the charging piece of the window cleaning robot through the charging port of the charging member 103, so as to charge the window cleaning robot 200.

[0055] Specifically, as Figure 1 , Figure 3 and Figure 6 shown, the charging member 103 charges the window cleaning robot 200 through an adapter 107 installed on the base body 101. The adapter 107 is specifically used to access the mains power and convert the mains power into a voltage suitable for charging the window cleaning robot 200 and supply it to the charging member 103. As Figure 3 shown, the adapter 107 is disposed on the base rear cover 106 of the base body 101. More specifically, a card slot 108 is provided on the outer side of the base rear cover 106, and the card slot 108 is used to place the adapter 107 on the base rear cover 106. In addition, a switch 109 of the window cleaning robot base is also provided on the outer side of the base rear cover 106, and the switch 109 is used to control the working state and power-off state of the window cleaning robot base.

[0056] The specific charging process of the base body 101 for the window cleaning robot 200 is described as follows. The charging port of the charging member 103 uses charging spring pieces 110 to charge the window cleaning robot 200. As Figure 2 shown, the charging spring pieces 110 are disposed at the charging port of the charging member 103. When the window cleaning robot 200 is placed at the charging position on the base body 101, the charging member 103 contacts the window cleaning robot 200 through the charging spring pieces 110 to achieve charging of the window cleaning robot 200.

[0057] The existing power sources for window cleaning robots mainly come from direct power supply by an adapter or power supply by a built-in rechargeable battery (such as lithium battery, nickel-chromium battery, etc.). When the window cleaning robot needs to be charged, the AC end of the adapter needs to be inserted into the mains power first, and then the DC end of the adapter needs to be inserted into the host, which is not very convenient to use. The window cleaning robot base of the present application also uses an adapter for charging. However, the window cleaning robot base charges the window cleaning robot in a direct contact manner. As long as the window cleaning robot 200 is placed on the window cleaning robot base, the charging piece of the charging interface of the window cleaning robot contacts the charging spring piece on the window cleaning robot base, and it can identify whether the window cleaning robot needs to be charged. Compared with the existing window cleaning robots, the window cleaning robot base of the present application is more convenient when charging the window cleaning robot.

[0058] The above-described process is the charging principle process of the window cleaning robot base for the window cleaning robot. The window cleaning robot base can also perform the function of automatically cleaning the window cleaning robot while charging the window cleaning robot.

[0059] If the traveling wheels of the window cleaning robot are used for too long, they will get dusty, which will cause the surface friction of the traveling wheels to decrease, resulting in the window cleaning robot slipping and unable to be used normally. The dust on the traveling wheels of the existing window cleaning robots is mainly cleaned manually, which is likely to cause a bad experience for users. The window cleaning robot base of the present application can quickly and automatically clean the traveling wheels. As long as the window cleaning robot is placed on the window cleaning robot base and meets the cleaning conditions, the window cleaning robot drives the traveling wheels to rotate forward and backward, so that the traveling wheels rub against the traveling wheel cleaning member 102 arranged on the window cleaning robot base to achieve the effect of automatic cleaning. Of course, it can also be achieved by rotating or swinging the traveling wheel cleaning member 102 on the base to rub against the traveling wheels. Among them, the traveling wheel cleaning member 102 is arranged on the base body 101 in a detachable and installable manner, that is, when the traveling wheels need to be cleaned, the traveling wheel cleaning member 102 is installed on the corresponding cleaning rack of the base body 101, and when the traveling wheels do not need to be cleaned, the traveling wheel cleaning member 102 can be removed. The principle of the window cleaning robot base cleaning the traveling wheels is described as follows:

[0060] Specifically, the window cleaning robot base cleans the traveling wheels of the window cleaning robot through the traveling wheel cleaning member 102, such as Figure 2 And Figure 6As shown, when the traveling wheel cleaning member 102 is installed on the base, and when the window cleaning robot is placed at the charging position on the base body, the window cleaning robot drives its traveling wheels to move and rub against the traveling wheel cleaning member 102, or rotates or swings through the traveling wheel cleaning member 102 on the base to rub against the traveling wheels to achieve the effect of automatic cleaning, so that the traveling wheels are cleaned. As mentioned above, the traveling wheel cleaning member 102 is arranged on the base body 101 in a detachable manner. In this embodiment, the detachable manner specifically uses a magic tape 111; that is, the traveling wheel cleaning member 102 can be arranged on the upper cover 104 of the base on the base body 101 through the magic tape 111. When the window cleaning robot 200 is placed at the charging position of the window cleaning robot base, the position where the traveling wheel cleaning member 102 is located is opposite to the traveling wheels at the bottom of the window cleaning robot. When the window cleaning robot 200 is arranged on the base body 101, for example, when the window cleaning robot 200 is arranged on the base body 101 for charging, the base body 101 detects the charging current. According to this charging current, the window cleaning robot confirms that it is at the charging position of the base, and will rotate the traveling wheels at the bottom of the window cleaning robot forward and backward. The traveling wheel cleaning member 102 rubs against the forward and backward rotating traveling wheels, thereby cleaning the traveling wheels. A time limit can be set for the above process in the control system of the window cleaning robot so that it can stop after the cleaning process achieves the cleaning purpose to save energy. Through the above process, the base of the window cleaning robot can automatically clean the traveling wheels of the window cleaning robot.

[0061] In addition, a water delivery system is arranged inside the base body 101, and the water delivery system is used to wet the cleaning cloth 300 for window cleaning of the window cleaning robot.

[0062] As Figure 5 shown, it is a schematic structural diagram of the water delivery system of the base. The water delivery system includes: a water tank 112, a water pump 113, a water delivery pipe 114, and a water spraying assembly 115. The specific principle of each component of the water delivery system for wetting the cleaning cloth 300 for window cleaning of the window cleaning robot is described as follows:

[0063] The water tank 112 can store a certain amount of water for wetting the cleaning cloth 300 for window cleaning of the window cleaning robot. The water pump 113 can provide the conveying power to pump the water in the water tank 112 through the water delivery pipe 114 to the water spraying assembly 115. As Figure 2 shown, the water spraying assembly is Figure 2Eight water spray outlets are arranged at both ends of the four grooves 116. The four grooves 116 are installed on the base upper cover 104 and surround the installation position of the traveling wheel cleaning member. Among them, the four grooves 116 are pairwise opposite to each other, and the total capacity of the four grooves is certain, that is, the maximum capacity of the four grooves 116 to receive the water sprayed by the water spray assembly 115 is certain. When the total water capacity of the four grooves 116 reaches the maximum, the amount of water can just provide an appropriate amount of water for the cleaning rag 300 used by the window cleaning robot to clean the window, ensuring that the moisture content of the cleaning rag 300 used by the window cleaning robot to clean the window is neither too much nor too little.

[0064] Specifically, the cleaning rag 300 is installed at the bottom of the window cleaning robot 200. When the window cleaning robot 200 is placed on the window cleaning robot base, for example, when the window cleaning robot 200 is placed on the window cleaning robot base for cleaning or charging, at least part of the cleaning rag 300 used by the window cleaning robot to clean the window is immersed in the four grooves 116, and the water sprayed from the eight water spray outlets at both ends of the four grooves 116 can flow into the four grooves 116. Among them, the water in the four grooves 116 is just used to wet the cleaning rag 300 used by the window cleaning robot to clean the window. It should be noted that the water output by the above water delivery system for wetting the cleaning rag 300 used by the window cleaning robot to clean the window is quantitative, and the quantitative water just wets the cleaning rag 300 used by the window cleaning robot to clean the window, which can ensure that the humidity of the cleaning rag 300 used by the window cleaning robot to clean the window is just right, neither too much nor too little. If the moisture content of the cleaning rag 300 used by the window cleaning robot to clean the window is too much or too little, it will affect the normal operation of the window cleaning robot. If the moisture content of the cleaning rag 300 used by the window cleaning robot to clean the window is too much, due to gravity, when the window cleaning robot works, too much water will enter the cabin of the window cleaning robot, causing the traveling wheels at the bottom of the window cleaning robot to slip, and the window cleaning robot cannot operate normally; if the amount of water in the cleaning rag 300 used by the window cleaning robot to clean the window is too little, when the window cleaning robot runs, the cleaning rag 300 used by the window cleaning robot to clean the window will float on the glass surface due to insufficient humidity and cannot effectively clean the glass. In this application, the capacity of the groove provided on the base upper cover is set corresponding to the amount of water required for the normal operation of the cleaning rag 300 used by the window cleaning robot to clean the window, so that the window cleaning robot base of this application can realize automatic quantitative water spraying for the cleaning rag 300 used by the window cleaning robot to clean the window.

[0065] Specifically, the above-mentioned base sprays water to wet the cleaning rag 300 through a rag water spraying starting unit. The water spraying starting unit is used to start the water delivery system of the base to spray water when the triggering water spraying condition is met. Specifically, the triggering water spraying condition can be set in various situations according to actual needs. In the following description, three triggering water spraying methods are taken as examples to illustrate the triggering water spraying condition:

[0066] The first triggering method: After detecting that the window cleaning robot 200 is placed on the base, the water spraying start unit on the base receives the detection result that the window cleaning robot 200 is placed on the base, and starts the water spraying of the water delivery system of the base. Specifically, whether the window cleaning robot 200 is placed on the base is detected by a base in-position detection unit inside the window cleaning robot 200.

[0067] The second triggering method: The water spraying start unit on the base detects that the water spraying start switch on the base is in the on state, and starts the water spraying of the water delivery system of the base. In specific implementation, the water spraying can be adjusted by adjusting the water spraying start switch installed on the base, that is, when the water spraying start switch is in the on state, the water spraying start unit starts the water spraying of the water delivery system of the base to wet the cleaning cloth. During this process, the water spraying start unit on the base can detect whether the water spraying start switch on the base is in the on state through a detector.

[0068] The third triggering method: When the base in-position detection unit detects that the window cleaning robot 200 is placed on the base and the water spraying start switch on the base is in the on state, the water spraying of the water delivery system of the base is started.

[0069] It should be noted that the above triggering methods are only specific implementation methods for triggering the water spraying of the water delivery system of the base in this embodiment, and are not used to limit the present application. For other conditions that meet the requirements for triggering the water spraying of the water delivery system on the base, they also belong to the protection scope of the present application.

[0070] In addition to the above functions of detecting whether the window cleaning robot needs to be charged and quickly charging it when it needs to be charged, automatically cleaning the traveling wheels of the window cleaning robot, and automatically quantitatively spraying water on the cleaning cloth 300 for window cleaning by the window cleaning robot, the base of the window cleaning robot of the present application also has a storage function.

[0071] Currently, the accessories of existing window cleaning robots mainly include: cleaning cloths, safety suction cups (including safety ropes), power adapters, remote controls, etc. These accessories of existing window cleaning robots are usually placed in a packing box. When using a window cleaning robot, the accessories need to be taken out of the packing box one by one, and after using the window cleaning robot to wipe the window, the accessories need to be put back one by one. The process of taking out and putting back each time is too cumbersome, which is likely to cause a bad experience for users. A storage box 117 is provided on the upper cover 104 of the base of the window cleaning robot base of the present application for storing the accessories of the window cleaning robot, which is convenient for users to take and place the accessories of the window cleaning robot when using the window cleaning robot.

[0072] Such as Figure 1As shown in the figure, a storage box 117 is provided on the upper cover 104 of the base of the window cleaning robot base. The storage box 117 is a slot structure divided into multiple slots, and each slot of the slot structure is used to store the remote control 400 of the window cleaning robot, the cleaning rag 300, and the safety suction cup 600 (including the safety rope)( Figure 4 ). A slot structure with multiple slots is provided as a storage box on the base of the window cleaning robot of the present application. Therefore, when the user uses the window cleaning robot of the present application to clean the window, it is convenient to take and store the accessories of the window cleaning robot.

[0073] In addition, an anti-slip device is also installed on the base, such as Figure 2 As shown in the figure, the base lower cover 105 is arranged at the bottom of the base body 101. The components of the above-mentioned water supply system, including the water tank 112, the water pump 113, and the water supply pipeline 114, are all arranged on the base lower cover 105. Among them, anti-slip pads 118 are installed at the four corners of the side of the base lower cover 105 facing the ground. This anti-slip pad 118 can keep the base of the window cleaning robot stably placed on the ground and will not slide when the ground is wet or the ground is relatively smooth.

[0074] Correspondingly, the present application provides a window cleaning robot that works corresponding to the above-mentioned window cleaning robot base, such as Figure 7 As shown in the figure, it is a schematic diagram of the working principle of the window cleaning robot provided by the present application corresponding to the above-mentioned window cleaning robot base. The window cleaning robot 200 includes: a base placement detection unit 201 and a traveling wheel cleaning start unit 202.

[0075] The base placement detection unit 201 is used to detect whether the window cleaning robot 200 is placed on the base, that is, whether the window cleaning robot 200 is placed in the correct position of the window cleaning robot base. In specific implementation, the window cleaning robot 200 can be detected whether it is placed on the base in the following two ways described.

[0076] The first detection method: The base placement detection unit 201 determines whether the window cleaning robot 200 is placed on the base by detecting whether a charging current flows through the base charging circuit of the window cleaning robot. If a charging current flows through, it is determined that the window cleaning robot 200 is placed on the base. More specifically, at this time, the window cleaning robot 200 is placed on the base in a charging manner. The base charging current refers to the circuit that provides the charging current in the base charging mode, specifically the current flowing in from the charging terminal corresponding to the charging port of the window cleaning robot base at the bottom of the window cleaning robot; since many models of window cleaning robots can also be directly charged through an adapter, it is necessary to detect the base charging current (not just the charging current) to determine whether the window cleaning robot is in the correct position.

[0077] In addition to the detection method described above, the base placement detection unit 201 can also detect whether the window cleaning robot 200 is placed on the base in another detection method. The specific detection method is described as follows:

[0078] Detect whether a special switch (not shown in the figure) provided at the bottom of the window cleaning robot is in the triggered position. If the special switch is in the triggered position, it is confirmed that the window cleaning robot 200 is placed on the base. Specifically, a trigger part corresponding to the special switch can be provided at a corresponding position on the base. When the window cleaning robot 200 just corresponds to the trigger part on the base, the special switch is in the triggered position, and the special switch can prompt the user that the special switch is in the triggered state in the form of an indicator light being on or a sound sounding.

[0079] More specifically, the special switch in the above process can be a spring compression detection device installed at the bottom of the window cleaning robot 200. When the traveling wheels at the bottom of the window cleaning robot are placed in a position directly opposite to the traveling wheel cleaning part 102 on the base, the spring compression detection device is pressed down due to being abutted by a boss provided on the base as a trigger part, so as to be in the triggered state, that is, the special switch is in the triggered state.

[0080] After the base placement detection unit 201 detects whether the window cleaning robot 200 is placed on the base, the traveling wheel cleaning start unit 202 is used to drive the traveling wheels at the bottom of the window cleaning robot to rotate when the condition for triggering the traveling wheel cleaning is met, so that the traveling wheels rub against the traveling wheel cleaning part 102.

[0081] The above conditions for triggering the traveling wheel cleaning can be set in multiple scenarios according to actual needs. In the following description, six triggering methods are taken as examples to illustrate the triggering conditions:

[0082] The first triggering method: The traveling wheel cleaning start unit 202 receives the detection result of the base placement detection unit 201 detecting whether the window cleaning robot 200 is placed on the base. If the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning part 102, thereby achieving the effect of cleaning the traveling wheels. Optionally, the base placement detection unit 201 can just adopt a charging detection unit installed inside the window cleaning robot 200.

[0083] In the second triggering method, the traveling wheel cleaning start unit 202 receives the detection result of the base placement detection unit 201 on whether the window cleaning robot 200 is placed on the base. If the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base and the window cleaning robot is charging, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102, thereby achieving the effect of cleaning the traveling wheels.

[0084] In the above process, detecting whether the window cleaning robot 200 is charging is achieved by a charging detection unit installed inside the window cleaning robot 200. Specifically, after the base placement detection unit 201 detects whether the window cleaning robot 200 is placed on the base, the traveling wheel cleaning start unit 202 receives the detection result provided by the base placement detection unit 201 and transmits the detection result to the charging detection unit. If the detection result is that the window cleaning robot 200 is placed in the correct position on the base, the charging detection unit starts the base to charge the window cleaning robot, and the charging detection unit simultaneously transmits a charging signal to the traveling wheel cleaning start unit 202. After receiving the signal, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102.

[0085] In the third triggering method, the traveling wheel cleaning start unit 202 receives the detection result of the base placement detection unit 201 on whether the window cleaning robot 200 is placed on the base. If the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base and the window cleaning robot is fully charged or the battery power is greater than a preset power value, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102, thereby achieving the effect of cleaning the traveling wheels.

[0086] During the above process, detecting whether the window cleaning robot 200 is fully charged or the battery power is greater than a preset power value is achieved through a charging detection unit installed inside the window cleaning robot 200. Specifically, after the base placement detection unit 201 detects whether the window cleaning robot 200 is placed on the base, the traveling wheel cleaning start unit 202 receives the detection result provided by the base placement detection unit 201 and transmits the detection result to the charging detection unit. If the detection result is that the window cleaning robot 200 is placed in the correct position on the base, the charging detection unit detects whether the window cleaning robot is in a fully charged state or whether the battery power is greater than the preset power value. If the charging detection unit detects that the window cleaning robot is in a fully charged state or the battery power is greater than the preset power value, it transmits a full charge signal or a signal indicating that the battery power is greater than the preset power value to the traveling wheel cleaning start unit 202. After receiving the signal, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, causing the traveling wheels to rub against the traveling wheel cleaning member 102.

[0087] For the fourth triggering method, the traveling wheels are cleaned by turning on the traveling wheel cleaning start switch. Specifically, the traveling wheel cleaning start unit 202 receives the detection result of the base placement detection unit 201 detecting whether the window cleaning robot 200 is placed on the base. If the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base and the traveling wheel cleaning start switch is turned on, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, causing the traveling wheels to rub against the traveling wheel cleaning member 102.

[0088] The above-mentioned turning on of the traveling wheel cleaning start switch can be specifically achieved by the user turning on the traveling wheel cleaning start switch. In a preferred embodiment, a switch for facilitating the user to turn on / off the traveling wheel cleaning function can be installed on the surface of the window cleaning robot 200. When the traveling wheel cleaning start switch is turned on, the traveling wheel cleaning start unit 202 receives the turn-on signal and drives the traveling wheels at the bottom of the window cleaning robot to rotate, causing the traveling wheels to rub against the traveling wheel cleaning member 102, thereby achieving the effect of cleaning the traveling wheels.

[0089] The fifth triggering method is to clean the traveling wheels when the window cleaning robot is charging and the traveling wheel cleaning start switch is turned on. Specifically, the user can decide whether to turn on the traveling wheel cleaning start switch by checking the charging indicator on the display screen installed on the surface of the robot: if the current state is that the window cleaning robot is not charging, the traveling wheel cleaning start switch is not turned on; if the current state is that the window cleaning robot is charging and the traveling wheels are dirty, the traveling wheel cleaning start switch is turned on. In a preferred embodiment, a switch for facilitating the user to turn on / off the traveling wheel cleaning function can be installed on the window cleaning robot 200. When the traveling wheel cleaning start switch is turned on, the traveling wheel cleaning start unit 202 receives the on signal and drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102, thereby achieving the effect of cleaning the traveling wheels.

[0090] The above charging process must be carried out after the base positioning detection unit 201 detects the result that the window cleaning robot 200 is placed on the base. Therefore, only when the window cleaning robot 200 is charging and the traveling wheel cleaning start switch is turned on, the traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102. The detection method for whether the window cleaning robot 200 is charging is the same as the detection method in the second triggering method above, and will not be elaborated here.

[0091] The sixth triggering method is to clean the traveling wheels when the window cleaning robot finishes charging and the traveling wheel cleaning start switch is turned on. Currently, many window cleaning robots turn on the traveling wheel cleaning function of the window cleaning robot when they are fully charged. Specifically, the user can decide whether to turn on the traveling wheel cleaning start switch by checking the battery level on the display screen installed on the surface of the robot: if the current state is that the window cleaning robot is not fully charged, the traveling wheel cleaning start switch is not turned on; if the current state is that the window cleaning robot is fully charged and the traveling wheels are dirty, the traveling wheel cleaning start switch is turned on. In a preferred embodiment, a switch for facilitating the user to turn on / off the traveling wheel cleaning function can be installed on the window cleaning robot 200. When the traveling wheel cleaning start switch is turned on, the traveling wheel cleaning start unit 202 receives the on signal and drives the traveling wheels at the bottom of the window cleaning robot to rotate, so that the traveling wheels rub against the traveling wheel cleaning member 102, thereby achieving the effect of cleaning the traveling wheels.

[0092] After the above process, the traveling wheel cleaning start unit 202, after receiving the detection result of whether the window cleaning robot 200 is placed on the base by the base placement detection unit 201, if the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base and the window cleaning robot 200 is in a fully charged state, then turns on the traveling wheel cleaning start switch. The traveling wheel cleaning start unit 202 drives the traveling wheels at the bottom of the window cleaning robot to rotate, causing the traveling wheels to rub against the traveling wheel cleaning member 102.

[0093] Of course, for the above fourth, fifth, and sixth triggering methods, the traveling wheel cleaning start switch can also be turned on through the automatic triggering unit of the traveling wheel cleaning start switch installed inside the window cleaning robot. The prerequisite is that when the traveling wheel cleaning start unit 202 receives the detection result of whether the window cleaning robot 200 is placed on the base by the base placement detection unit 201, if the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base, or the charging detection unit detects that the window cleaning robot 200 is placed on the base and is charging, or the charging detection unit detects that the window cleaning robot 200 is placed on the base and is fully charged, the traveling wheel cleaning start unit 202 or the charging detection unit transmits the corresponding signal to the automatic triggering unit of the traveling wheel cleaning start switch. The automatic triggering unit of the traveling wheel cleaning start switch turns on the traveling wheel cleaning start switch. After the traveling wheel cleaning start unit 202 detects that the traveling wheel cleaning start switch is turned on, it drives the traveling wheels at the bottom of the window cleaning robot to rotate, causing the traveling wheels to rub against the traveling wheel cleaning member 102.

[0094] Through the above six triggering methods, the purpose of cleaning the traveling wheels can be achieved. In some triggering methods, the user can turn on or off the traveling wheel cleaning switch according to actual needs to control the start or stop of the traveling wheel cleaning process, enhancing the user experience; in other triggering methods, the window cleaning robot automatically cleans the traveling wheels and can also automatically stop the cleaning process after a period of time. In addition, the user can select the above triggering modes according to actual needs through the display screen on the control panel of the window cleaning robot, further enhancing the user experience. Of course, regardless of which triggering method is adopted, the prerequisite is to ensure that the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base. After confirming that the base placement detection unit 201 detects that the window cleaning robot 200 is placed on the base, if the conditions for cleaning the traveling wheels are met, the traveling wheel cleaning start unit 202 drives the traveling wheels of the window cleaning robot to rotate forward and backward, causing the traveling wheels to rub against the traveling wheel cleaning member installed on the base of the window cleaning robot to achieve the effect of automatic cleaning. Of course, it can also be achieved by rotating or swinging the traveling wheel cleaning member on the base to rub against the traveling wheels to achieve the effect of automatic cleaning.

[0095] The base placement detection unit 201, the charging detection unit, the traveling wheel cleaning start unit 202, and the rag water spraying start unit are all functional units abstracted from the perspective of logical functions. In actual implementation, the base placement detection unit 201 may include corresponding detection elements. For example, in the way of determining whether the window cleaning robot is placed in the correct position of the base by detecting the charging current of the base as described above, a detection resistor connected in series to the charging terminal of the base can be used as the detection element. The detection current situation can be obtained by detecting the voltage drop across this detection resistor, so as to determine that the window cleaning robot is in the charging state. By connecting the voltage across this detection resistor to the detection port of the control system of the window cleaning robot, the control system can obtain the detection result. In the above implementation solution, the overall composed of the detection resistor, the corresponding detection port of the control system, and the part in the control system that makes a judgment based on the input of the detection port (such as a comparator) can be regarded as the base placement detection unit 201. The charging detection unit, the traveling wheel cleaning start unit 202, and the rag water spraying start unit are actually implemented by relevant programs or program segments stored in the control system. After the base placement detection unit 201 provides the placement signal that the window cleaning robot is placed on the base, the base starts the charging function, or the cleaning function or the water spraying function for the window cleaning robot, drives the traveling wheels to rotate during the cleaning process, and the rotation process includes forward rotation and reverse rotation, each lasting for a certain period of time, and these processes are all recorded in the program.

[0096] In the above embodiments, a base of a window cleaning robot with charging, cleaning, humidifying and storage functions and a corresponding window cleaning robot are respectively provided.
