Background technique

With the diversification of user needs and the wide variety of cleaning robots, the cleaning robot can wipe the ground to improve the cleanliness of the ground.

Existing cleaning robots can use a mop for mopping when performing cleaning work. Specifically, the mop is connected to the mopping floor or the machine body, and the ground is cleaned by a moist mop. When supplying water to the mop, most adopt the method of natural water supply, that is, let the water in the water tank flow naturally to the mop to soak the mop at a certain rate. However, when the cleaning robot encounters a situation such as no electricity or stuck, the uninterrupted water supply of the water tank will cause the mop to bubble or the ground to generate a large amount of water, which will damage the floor.

Therefore, users need to take care of the robot by themselves to help the robot deal with the situation of no electricity or stuck. For users, such human participation will reduce the robot's automated operation experience.

The lifting frame 19 drives the mopping module 40 to swing under the action of the swing mechanism, thereby adjusting the distance of the mopping module 40 relative to the working surface. The specific structure is to adjust The common structure of the device will not be repeated here.

As shown in FIG. 8, the mopping module 40 is installed on the fixing plate 11 through magnetic attraction. Specifically, the mopping module 40 is provided with magnetic elements 18 such as magnets, magnetic strips, etc. The magnetic element can be attracted, and the mopping module 40 can also be installed on the fixing plate 11 by providing pin holes on the mopping module 40 and cooperating with corresponding pins provided on the fixing plate 11. A protruding device (not shown in the figure) is provided on the top of the fuselage, such as a top post or a convex ball, etc. The protruding device generates relative motion with the mopping module 40 and contacts the mopping module 40, thereby mopping the ground The module 40 is separated from the body 11. The number of the protruding devices is 2, and the projection of the mopping floor falls on both ends of the mopping floor. Of course, the number of the protruding devices may be one or more.

The mopping module of the cleaning robot has at least three height positions relative to the work surface driven by the lifting mechanism: the first position when the cleaning robot performs the mopping work, the second position when the cleaning robot walks or crosses obstacles, etc. The third position when the mop 28 is unloaded, where the third position is higher than or equal to the second position, the first position is lower than the second position, and the position of the mopping module can be adjusted by the lifting mechanism, so that the cleaning robot can be mopped and overrun , Automatic replacement of mop and other needs. Of course, in addition to the above three height states, the cleaning robot may also have a fourth position below the first position for installing a new mop.

9-12 is a schematic diagram of a scene of a cleaning robot working process, and the positional relationship of the mopping module 40 will be described according to the schematic diagram of the scene. As shown in Figure 9, when the cleaning robot is in the working state of mopping, the lifting mechanism controls the mopping module in the first position. At this time, there is a certain pressure between the mop and the ground, and the mop can contact the ground and have a certain The interference amount, so as to achieve a better cleaning effect; when the cleaning robot encounters an obstacle during the mopping process, the lifting mechanism controls the mopping module to be in the second position shown in FIG. 10, at this time, the mopping module will Automatically lifted, the second position is higher than the working height, but the height can not be higher than the height of the unloading mop, to prevent the mop and mopping floor from falling off; when the cleaning robot needs to replace the mop during the mopping process or the power is low during the mopping process When the preset threshold value needs to return to charging, the lifting mechanism controls the mopping module to be raised to the second position as shown in FIG. 10, and at the same time, the cleaning robot can also form the position coordinates of its previous position through the navigation mechanism and put the position coordinates in Marked in the work area map; when the mop is replaced, the lifting mechanism controls the mop to be lifted to the third position shown in FIG. 11 to unload the mop, thereby realizing the separation of the mop module and the fuselage shown in FIG. 12. The old mop can be unloaded to the first operating position as shown in FIG. 1. This first operating position can be used to complete the disassembly of the old mop; after the old mop is unloaded, the cleaning robot will automatically install the new mop. The cleaning robot can Complete the installation of the new mop in the second operating position. After the machine enters the corresponding position, the mopping module is attracted to the fuselage through magnetic attraction. Specifically, the mop module is provided with a magnet and the magnetic element is provided on the fuselage. After the new mop is installed or fully charged, the lifting mechanism controls the mopping module to the second position and sets off to return to the position marked on the work area map. When the marked position is reached, the lifting mechanism controls the mopping module Adjust to the first position to continue mopping; when the cleaning robot needs to suspend mopping during mopping, the lifting mechanism controls the mopping module to lift to the second position. The above-mentioned lifting mechanism is used to control the mop to be lifted when it crosses an obstacle, which solves the problem that the mopping module of the cleaning robot in the prior art is caused by the second position state when the ground is only mopped during the work, and the height of the obstacle is almost 0 Can clean defects with limited range. The mopping module can control the lifting mechanism to raise the mop to the second position when the mopping is suspended, which solves the state of the prior art because the mopping module only exists in the second position when mopping, so the floor is soaked in the liquid and the floor is damaged Defects. The cleaning robot can return to the mopping position before replacing the mop and continue to drag after the mop replacement or charging is completed, which solves the defects in the prior art of repeatedly mopping the area that has been dragged and leaking the area that has not been dragged. The cleaning efficiency of the cleaning robot is improved. In addition, the mop can be automatically replaced, which improves the degree of automation of the cleaning robot and the user experience.

In one embodiment of the present application, the cleaning robot detects whether the liquid reservoir is installed on the cleaning robot when it starts to work. When it is detected that the liquid reservoir is not installed on the cleaning robot, the cleaning robot cannot start and start working, and the control module Control the cleaning robot to transmit information to the user that the liquid storage is not installed. The information received by the user may be an alarm issued by the machine itself or a reminder message on the app. When the liquid reservoir is detected, the cleaning robot starts to work.

When users use floor mopping robots, they will choose different cleaning modes according to the dirt on the ground. It is generally divided into two modes: dry drag and wet drag. The dry mop mainly deals with dust and hair and other stains, and the wet mop mainly deals with adhesion stains that are difficult to clean. Due to the complex ground conditions at home, it is often necessary to mix the two modes. When performing cleaning work in the prior art, the user needs to observe the working condition of the machine on the spot. When the robot is seen to complete the wet or dry mop work, the user manually inputs an instruction to control the machine to start the wet or dry mop mode again. This method is cumbersome.

In an embodiment of the present application, the default working mode of the cleaning robot is: first perform the dry drag work and then perform the wet drag work, that is, when the user starts the cleaning robot to enter the working state, the cleaning robot may first dry drag the work area, When it is detected that the dry mopping work is completed, wet mop the work area. This can prevent defects such as hair and other wastes from easily sticking to the work area when the user does not vacuum the work area when the work area is wetly dragged. Further, the cleaning robot can intelligently switch between dry mop and wet mop working modes during the work process, and automatically perform wet mop work after the dry mop in the area is completed, without the need for the user to observe the working condition of the machine, and the user does not need to When the dry towing is completed, the machine is manually controlled to start the wet towing mode. Using the method in this embodiment can save user time and improve the user experience.

Of course, in other embodiments, the user can change the default working mode in the human-computer interaction on the app or the cleaning machine body according to the actual stain situation of the user's home ground or the user's own needs, such as changing the default working mode For: only dry mop, wet mop only, wet mop first and dry mop, etc., this application does not limit this.

In an embodiment of the present application, after the robot completes the drawing, the working area may be divided into at least one preset area according to the preset area division method in the cleaning robot app, or the user may The working area is divided into at least one preset area. After the area is divided, the robot can first dry-drag one of the preset areas according to the working mode of first dry drag and then wet drag. When the robot is based on the walking path recorded in the map or After the walking distance recorded by the self-carried sensor determines that it has completed the dry drag in the preset area, the wet drag is continued on the preset area. After completing the wet drag operation, you can continue to go to another preset area according to the program settings to perform the dry and wet drag operation similar to the above method. Of course, after building the map and dividing the area, the robot can also first dry-drag the entire work area, and after judging the completion of the dry-drag work of the entire work area, perform the wet-drag work on the entire area.

Further, in an embodiment of the present application, when it is detected that the wet towing work is completed, the cleaning robot can be controlled to dry tow the work area so that the user can enter the work area as early as possible without staining the wet work area . When the cleaning robot is in the process of dry mopping, if it detects coffee, milk and other liquids, you can avoid cleaning these areas first, and then change to wet mop mode, then clean these areas to prevent dry mop Sticking these liquids for cleaning will cause defects in other areas contaminated by these liquids. Corresponding to the working mode of the cleaning robot, a corresponding number of dry mop and wet mop are placed on the base station, or only dry mop is placed on the base station, and the liquid is delivered to the mopping module through the liquid supply device to achieve the purpose of wet mop.

In an embodiment of the present application, before the cleaning robot performs wet or dry mopping, it is controlled to transmit information to the user that the mop is to be replaced, or the cleaning robot is controlled to at least replace the mop. After the user receives the message on the machine or app reminding that the mop needs to be replaced, the user can choose to manually replace it or choose to control the machine to automatically replace the mop or mop module. The mop is detachably installed on the mop module, so when replacing You can just replace the mop. After the cleaning robot completes the dry mop, it can also automatically return to the base station to replace the new mop, and after replacing the new mop, perform the wet mop. When the mop of the dry mop is used for wet mop, because the mop of the dry mop is often in a dirty state, if the mop of the dry mop is directly wetted, the stains (dust and hair) on the dry mop will be brought into the preparation of the wet mop The ground caused a secondary pollution of wet towed ground, which reduced the cleaning efficiency of wet towed. Therefore, by controlling the machine to switch between different modes, the mop is replaced to ensure that the machine can achieve the best cleaning effect when entering the new cleaning mode.

In one embodiment of the present application, the cleaning robot can fully moisten the mop by the following means before wet mop, so that at the beginning of the wet mop mode, the water injected onto the mop can be completely in the mop in a short time Spreading on top makes the moist mop area increase, so as to improve the cleaning efficiency of the mopping robot at the beginning of wet mop. During the normal wet drag operation of the cleaning robot, the liquid supply device can transfer liquid to the mopping module according to the preset power and preset time, then before the wet drag, the cleaning robot can increase the transfer when the liquid supply device works normally The power of the liquid, that is, before the start of the wet drag operation, the liquid can be delivered to the liquid supply device according to a power greater than the preset power, and after working for a period of time, it is reduced to the power during normal operation. Similarly, the liquid may also be delivered to the liquid supply device at a time greater than the preset time, and after a period of operation, the liquid may be reduced to the delivery time during normal operation.

In another embodiment of the present application, the cleaning robot can also be controlled to wet the mop by walking in a preset path before starting the wet towing, for example, the mopping robot can be controlled to start moving according to the program forward, backward, steering, etc. The liquid accumulated on the mop is completely absorbed by the mop to achieve the purpose of moistening the mop in a large area. After the cleaning robot installs the mop and walks to the starting position with the mopping module raised, it can walk forward and backward near the starting point to moisten the mop. When it is detected that the mop has been fully wetted, the cleaning can be controlled The robot walks to the starting position of the wet tow and starts the wet towing from the starting position. The cleaning robot fully moistens the mop before the mop, to ensure that only when the mop is moistened near the seepage point, the cleaning effect is poor.

In an embodiment of the present application, after the cleaning robot completes all mopping work in the work area, the control module may control the cleaning robot to transmit information to the user to unload the wiper, or at least unload the wiper. After the cleaning robot completes the mopping work in the work area required by the user to clean, it can control the cleaning robot to transmit the information of unloading the mop to the user, or unload the mop, or unload the mopping module; it can also transmit the information of the mop to be replaced to the user , Or replace the mop, or replace the mopping module. By using the method in this embodiment, it can be ensured that after the entire mopping work is completed, the cleaning robot will not have the old contaminated mop, which avoids the phenomenon of mold and odor caused by not cleaning the old mop in time. Furthermore, the unloaded wipes can also be recycled to avoid contaminating the user's home with the old mop unloaded on the ground or the base plate of the base station. Specifically, the user may be sent a message to uninstall the mop through the signal sending module, or the user may be notified to uninstall the mop through an instruction unit installed on the fuselage, or the cleaning robot may go to the base station to uninstall the mop by itself. When the user manually uninstalls the old mop on the robot, the user can directly throw away the old mop, or install a new mop on the robot. When the robot is controlled to unload the mop by itself, the robot can return to the base station to unload the dirty mop. As shown in FIG. 1, the cleaning robot walks to the base station and completes the unloading of the old mop at the first operating position 201. After exiting the base station, the mop replacement device of base station 300 The old mop is recycled to the old mop slot 204, and then the robot directly travels to the base station to stand by, or the cleaning robot can also install a new mop and stand by, which is not limited in this application. After that, after a certain number of mops have been collected in the old mop trough 204, the user can collectively process the old mop.

In an application scenario, the user controls the machine in the app to work in accordance with the default "dry-drag-on-wet-drag" work mode, and controls the robot to dry-drag and then wet-drag the work area. After receiving the user's instruction, the robot can dry-pull the work area first. During the dry-pulling process, the liquid transfer device is controlled to be locked and closed. After the dry-pulling of the entire work area is completed, the robot automatically returns to the base station to replace the mop. After replacing the mop, control the machine to walk to the starting point when the mopping module is in the lifted state to start the wet mopping work. When walking to the starting point, put down the mopping module and transfer the liquid through the liquid transfer device to realize the wet mopping. Before starting the wet mop, increase the power of the liquid transfer device and control the machine to move forward or backward near the starting point to make the liquid fully moisten the mop. When it is detected that the mop fully wets the liquid, return to the starting point Wet mopping is started. When the wet mopping work in the entire work area is completed, the control machine returns to the base station to unload the old mop, install a new mop and stand by.

In the embodiment of the present application, in the wet drag mode, when it is detected that the cleaning robot is in a preset condition described below, the control module may restrict the liquid supply device to transfer liquid to the mopping module. Solve the problem that the cleaning robot in the prior art encounters a situation such as no electricity or stuck, the uninterrupted water supply of the water tank will cause the mop to bubble or the ground to generate a large amount of water, and the problem of foaming the floor can protect the cleaning robot and protect the floor Not to be damaged by liquid, and to ensure the purpose of mopping effect. Restricting the liquid supply device to transfer liquid to the mopping module may be to control the liquid supply device to stop transferring liquid to the mopping module; or it may be to control the liquid supply device to mop compared to the case where the liquid supply device transfers liquid in the wet drag mode The module delivers less liquid.

In the embodiment of the present application, when the cleaning robot is in the wet drag mode, the control module restricts the liquid supply device to transfer liquid to the mopping module when an abnormality of the cleaning robot is detected.

In an embodiment of the present application, the control module may restrict the liquid supply device to transfer liquid to the mopping module when it is detected that the cleaning robot is trapped or stuck or the controller malfunctions. For example, an abnormal situation that is trapped by an obstacle or the drive wheel falls into a recessed area.

In another embodiment of the present application, the cleaning robot may further include a mop detection device 90 electrically connected to the control module, the mop detection device 90 is used before the cleaning robot starts to perform the mopping work or the process of performing the mopping work In the process, it is detected whether the mop is installed on the cleaning robot. If it is not abnormal, the control module restricts the liquid supply device to transfer liquid to the mop; if the mop is installed on the cleaning robot, the mopping work is started. A magnetic connection may be adopted between the mop and the mopping floor. Therefore, in this embodiment, the mop detection device 90 may be a Hall sensor.

In the embodiment of the present application, when the cleaning robot is in the wet mopping mode, the control module restricts the liquid supply device to transfer liquid to the mopping module when it is detected that the mopping module is at a non-mopping height within a preset time period.

In an embodiment of the present application, the cleaning robot further includes a lifting mechanism, and the control module controls the lifting mechanism to lift the mopping module from the first position to the second position relative to the work surface when performing the mopping work. When the mopping module is in the wet mopping mode, when it is detected that the mopping module satisfies the lifting state within a preset time period, the liquid supply device is restricted from transferring liquid to the mopping module. The preset time period may be set by the user or preset in the app system, which is not limited in this application.

Specifically, the control module controls the lifting mechanism to lift the mopping module from the first position to the second position relative to the work surface under the following circumstances, which may include but not limited to at least one of the following: the cleaning robot returns to the base station to replace the mopping module, The cleaning robot is in a state where the floor is suspended and suspended. When the cleaning robot is trapped or stuck during the mopping process, in order to prevent the mopping module from damaging the floor, the lifting mechanism can be controlled to lift the mopping module from the first position to the second position relative to the work surface, and limit Liquid supply.

In an embodiment of the present application, when the cleaning robot detects a non-working surface during work, the control module controls the lifting mechanism to lift the mopping module from the first position to the second position relative to the working surface, To control the cleaning robot to cross the non-working surface. When the cleaning robot crosses the non-working surface, when it is detected that the mopping module satisfies the state of being lifted within a preset time period, the liquid supply device is restricted from transferring liquid to the mopping module. Further, after detecting that the cleaning robot crosses the non-working surface, the control module controls the lifting mechanism to lower the mopping module from the second position relative to the working surface to the first position, and the liquid supply device transfers liquid to the mopping module.

As shown in the application scenario where the non-working surface is a carpet as shown in FIGS. 13-16, when the cleaning robot detects the carpet 35 during the mopping of the first position 34 relative to the ground, the control module controls the lifting mechanism to move the mopping module 40 Raised from a first position 34 relative to the ground to a second position 36 to control the cleaning robot to cross the carpet. During the process of the cleaning robot crossing the carpet, the mopping module 40 has been in a lifted state, and during the process of the cleaning robot crossing the carpet, the liquid supply device stops sending liquid to the mopping module to ensure that the mop is not stained by the floor and the carpet is not Wet by mop. When it is detected that the cleaning robot has passed the carpet, the control module controls the lifting mechanism to lower the mopping module from the second position 36 to the first position 34, and the liquid supply device resumes the state of transferring liquid to the mopping module, ensuring that the machine can perform mopping normally jobs.

In another embodiment of the present application, when the cleaning robot is in the wet mop mode, the control module restricts the liquid supply device from transferring liquid to the mopping module while the cleaning robot is in the process of replacing the mop or mopping module.

In another embodiment of the present application, when it is detected that the cleaning robot is currently in at least one of the following mopping conditions, such as: the cleaning robot is in a dry towing mode; the cleaning robot returns to the base station for charging and the cleaning robot is charging When the user is lifted by the user or when the obstacle is lifted, all or part of the walking elements of the mopping robot leave the ground, etc., the control module can control the liquid supply device to stop transferring liquid to the mopping module.

In the embodiment of the present application, during the wet towing process, when the above-mentioned abnormal situation or the lifting state is detected or some components are removed from the ground, etc., for example: the controller failure and other abnormalities are repaired, the robot returns to the ground, etc., control The module controls the liquid supply device to resume normal liquid supply to the mopping module.

In this embodiment, the cleaning robot can control the liquid delivered by the liquid supply device to the mopping module according to the current mopping situation detected by at least one sensor set below, thereby ensuring the mopping effect.

In the embodiment of the present application, the cleaning robot may further include: a humidity detection device, which controls the liquid supply device to transfer liquid to the mopping module through the current mopping situation detected by the humidity detection device. The current mopping situation may include, but is not limited to, at least one of the following: mop humidity, ground humidity, ambient humidity, and the like. Specific application scenarios are described below.

In one embodiment, the humidity detection device may include a mop humidity sensor, and the control module controls the liquid delivered by the liquid supply device based on the mop humidity detected by the mop humidity sensor. Preferably, the mop humidity sensor may be installed under the fuselage, for example: a capacitance sensor and/or a current sensor. The mop humidity detected by the mop humidity sensor monitors the current mopping situation and sends the mop humidity to the control module, which controls the amount of liquid delivered by the liquid delivery device based on the mop humidity detected by the mop humidity sensor. Specifically, when the mop humidity is greater than the preset threshold, the liquid delivery device is controlled to output liquid at a rate lower than the current discharge rate; conversely, when the mop humidity is less than the preset threshold, the liquid delivery device is controlled to be higher than the current discharge rate The rate of output liquid. The preset threshold may be set by the user according to the current ground situation, and the preset threshold in different areas may be different.

In another embodiment, the humidity detection device may include: an environmental humidity detection device, which may control the liquid delivered by the liquid supply device through the environmental humidity detected by the environmental humidity detection device. Wherein, the environmental humidity detection device may control the liquid delivered by the liquid supply device based on the environmental humidity detected locally and/or remotely. The environmental humidity detection device may be an air humidity sensor or a humidity measuring instrument installed on the cleaning robot. The air humidity sensor or the humidity measuring instrument may be installed at a position that meets a certain distance from the water source of the cleaning robot, thereby avoiding cleaning the liquid in the robot The measurement result of the environmental humidity detection device is affected, which facilitates more accurate detection of the environmental humidity of the cleaning robot, so as to control the liquid delivered by the liquid supply device based on the detected environmental humidity. The cleaning robot can also detect the environmental humidity in a remote way. At this time, the cleaning robot accesses the network by means of cellular or wifi, etc. The cleaning robot receives the weather condition sent by the server and controls the amount of liquid delivered by the liquid delivery device based on the weather condition. When the ambient humidity is greater than the preset threshold, the liquid delivery device is controlled to output liquid at a rate lower than the current discharge rate; conversely, when the ambient humidity is less than the preset threshold, the liquid delivery device is controlled to output at a rate higher than the current discharge rate liquid. The preset threshold may be set by the user according to the current ground situation, and the preset threshold in different areas may be different.

In another embodiment, the humidity detection device may include: a ground humidity sensor, such as a vision sensor and/or a radar sensor, and the control module may control the liquid delivered by the liquid supply device based on the ground humidity detected by the ground humidity sensor, and may The humidity value of the area in the mopping app is updated in real time according to the detected ground humidity. The floor humidity sensor can control the liquid delivered by the liquid supply device based on the detected floor humidity or dryness. Normally, the cleaning robot can mopp the floor according to a predetermined walking path. However, for some areas, when the cleaning robot detects that the ground in this area is dry, it can spray more liquid or increase the working time of the cleaning robot until the ground condition detected by the ground sensor meets the preset cleaning requirements. The robot stops cleaning the area; or when it is detected that the ground is wet in some areas, the liquid transfer device can reduce the amount of liquid transferred or stop the amount of liquid transferred. For example, when the cleaning robot passes through the same area in a short time, the liquid transfer device can be controlled to reduce or stop the supply of liquid, which can avoid wasting liquid or avoiding the wheel slipping during the walking of the robot. In a specific application scenario, when the robot drags the ground in some areas, and then turns and walks repeatedly to some positions in these areas, if the liquid supply continues, it will cause too much liquid on the ground, causing the machine to slip or waste. Liquid, so when it is detected that the robot repeatedly walks in the same area in a short time, the liquid delivery device can be controlled to stop the liquid supply.

In an embodiment of the present application, the cleaning robot may further include: a ground sensor, such as a vision sensor and/or a radar sensor, the ground state detected by the ground sensor, and sending the ground state to the control module to control The module can control the liquid delivered by the liquid supply device. Specifically, the ground state may include: ground materials, etc. The ground sensor can detect the material of the working surface, such as a floor or ceramic tile, etc., and the control module can control the amount of liquid transmitted by the liquid delivery device to the mopping module according to the ground state detected by the ground sensor. When the cleaning robot detects that the ground material is a wooden board, it can control the amount of water discharged from the liquid delivery device, appropriately reduce the amount of water supplied by the mop, and prevent excessive water from damaging the wooden floor. In one embodiment, the ground sensor includes a visual sensor, and the control module can determine the material of the work surface based on the ground image acquired by the visual sensor; in another embodiment, the ground sensor can include a radar sensor, and the control module can detect the radar sensor. The results determine the type of work surface.

In one embodiment, the cleaning robot may further include a signal sending device that can detect the current mopping situation detected by the humidity detection device (which may include: mop humidity, ground humidity, ambient humidity, etc.) or a ground sensor The ground status is sent to the user. For example, in addition to reading the ground humidity in the current area from the display on the cleaning robot body; the user can also read the ground humidity in the current area from the mopping app according to the ground humidity sent to the user by the signal sending device. When the user feels that he can increase or decrease the amount of liquid dragging the floor, he can also send a corresponding signal to the cleaning robot, so that the control module can control the liquid delivered by the liquid supply device based on the instruction sent by the user. The above method is used to intelligently control the liquid supply device in the cleaning robot to transfer liquid to the mopping module, thereby improving the user experience of the cleaning robot.

Further, in an embodiment of the present application, the cleaning robot may include: a navigation mechanism. The user can perform area calibration on the map of the working area of the cleaning robot formed by the navigation mechanism, and set the liquid condition that the cleaning robot needs to use in each area, so that the control module can control the liquid reservoir to transfer in each area based on the liquid condition The corresponding liquid can also be combined with the ground humidity in the current area updated based on the ground humidity sensor in real time to determine whether the liquid supply in the current area meets the user's needs based on the real-time updated ground humidity. If not, continue the liquid supply. Then you can stop mopping the current area. In this embodiment, the navigation mechanism used may include but is not limited to at least one of the following: ultrasonic sensors, optical sensors (including: LDS, etc.), UWB sensors, and inertial navigation systems.

In an embodiment of the present application, the cleaning robot may further include: a liquid level monitoring device provided in the liquid reservoir. In one embodiment, when the liquid level monitoring device detects that the liquid level in the liquid reservoir is below a preset threshold, a notification message may be sent to the user that the amount of liquid in the cleaning robot is insufficient, and the notification message may include the cleaning robot The remaining liquid adopts the time that the current discharge rate can still be used. The user can choose not to respond when receiving this notification message, can control the cleaning robot to suspend work, can also choose to lower the liquid output rate, or choose to add liquid to the cleaning robot.

In another embodiment, the cleaning robot may further include: an indicating device, such as a light-emitting indicating device (LED, etc.) or an audible indicating device, which may be used to indicate whether the cleaning robot has sufficient liquid or may also be used to indicate Whether the liquid reservoir is installed on the robot. When the liquid volume is insufficient, the instruction unit can send out the voice message "Master, the water volume is insufficient, please add water to me". The state of the indicating device when the amount of liquid is not lower than the preset threshold is different from the state when it is lower than the preset threshold. The user monitors the liquid level in the liquid reservoir by observing the different states of the indicating device. By reminding the user that the amount of liquid is insufficient, the defect of poor cleaning effect due to lack of liquid is prevented, and the mopping effect of the cleaning robot is improved.

Further, the cleaning robot may further include at least two liquid reservoirs, and the at least two liquid reservoirs are symmetrically arranged on both sides of the fuselage. Put different types of liquids in the two liquid reservoirs respectively, and control the liquid delivery device corresponding to the liquid reservoirs to work synchronously or asynchronously through the control module, so as to achieve the purpose of cleaning different types of stains. Of course, the cleaning robot may also include three, four, or more than two liquid reservoirs. These different liquid reservoirs may be placed with the same or different types of liquids according to actual needs, which is not limited in this application.

The cleaning robot may include a ground sensor, for example, a visual sensor, which detects the ground state through the ground sensor and sends the ground state to the control module, so that the control module can separately control the amount and type of liquid transmitted by the two liquid reservoirs. The ground condition may include: ground material and/or ground stain type. The ground sensor can control the amount of liquid transferred from the two liquid reservoirs to the mop based on the detected ground material condition, whether the ground stain is oil or dust, where the amount of liquid transferred can be 0, that is, it can be controlled to use only One of the liquid reservoirs. Normally, the cleaning robot can mopp the floor according to a predetermined walking path. However, for some areas, when the cleaning robot detects that the ground in this area is dry and has a lot of oil, it can spray more liquid or increase the working time of the cleaning robot until the ground condition detected by the ground sensor meets the preset cleaning requirements At this time, the cleaning robot stops cleaning the area. In this embodiment, the liquids transferred from the two liquid reservoirs to the mopping module can be controlled separately until the ground condition detected by the ground sensor meets the preset cleaning requirements, and the cleaning robot stops cleaning the area.

The cleaning robot may further include: a navigation mechanism. The user can perform area calibration on the map of the cleaning robot working area formed by the navigation mechanism, and set the amount of liquid and the type of liquid that the cleaning robot needs to use in each area, so that the control module can control based on the amount of liquid and the type of liquid The liquid transfer device transfers the corresponding amount of liquid and the type of liquid in each area.

The cleaning robot may further include a signal sending device, which may send the humidity of the mop detected by the humidity sensor or the ground status detected by the ground sensor to the user, and the user may read the current mopping situation on the display on the cleaning robot body You can also read the current mopping situation in the mopping app. For example, when the user feels that it is possible to increase or decrease the amount of liquid dragging the floor, he can also send a corresponding signal to the cleaning robot, so that the control module can control the amount of liquid and the type of liquid delivered by the liquid delivery device based on instructions from the user. The instruction can be sent through the mopping app or can be directly input by the user on the interactive interface of the cleaning robot. Using the above methods to intelligently control the mopping humidity of the cleaning robot and the type of mopping liquid improves the user experience of the cleaning robot. Further, the cleaning robot may further include: a liquid level monitoring device respectively provided in the two liquid reservoirs. The liquid level monitoring device is used for monitoring whether the liquid level in the liquid reservoir is lower than a preset threshold, and may also include Indicating devices corresponding to the two liquid level monitoring devices respectively for indicating the liquid level.

In the following, a specific embodiment with two liquid reservoirs will be described respectively.

As shown in FIGS. 5 and 6, both liquid reservoirs are present. It is worth noting that the first and second before all kinds of devices in this application are to distinguish these two devices from different devices, and do not have other special meanings, such as: the first hose and The second hoses are all hoses, but they are two different hoses. At the same time, in this application, only two liquid reservoirs are taken as an example for description, or more than two liquid reservoirs may be used, the principle is the same, This application will not repeat them.

Figure 5 shows the dual-liquid storage device dual-liquid storage device. The first liquid reservoir 511 is connected to the first liquid delivery device 501 through the first hose 521, the second liquid reservoir 512 is connected to the second liquid delivery device 502 through the second hose 522, the first liquid delivery device 501 and the first The two liquid conveying devices 502 are electrically connected to the control module respectively. The control module may select the first liquid conveying device 501 or the second liquid conveying device 502 to transmit liquid to the mop at the same time or separately based on the current mopping requirements, or may select the first liquid conveying The device 501 or the second liquid transfer device 502 transfers the amount of liquid to the mop simultaneously or separately, thereby ensuring the mopping effect. For example, the first liquid storage 511 stores fresh water, the second liquid storage 512 stores cleaning liquid, and when the ground sensor detects that only dust exists on the ground, the control module controls the first liquid delivery device 501 to work The first liquid reservoir 511 transfers clean water to the first liquid transfer device 501 through the first hose 521, so that the first liquid transfer device 501 transfers clean water to the mop, and uses the clean water to remove dust and the like on the ground. When the ground sensor detects that there is still oil on the ground, the control module controls the operation of the first liquid delivery device 501 and the second liquid delivery device 502, that is, the first liquid reservoir 511 passes through the first hose 521 While transferring clean water to the first liquid transfer device 501, the second liquid storage device 512 also transfers the cleaning liquid to the second liquid transfer device 502 through the second hose 522 so that the second liquid transfer device 502 transfers the cleaning liquid to the mop due to The concentration of the cleaning liquid is high, so the working time of the second liquid delivery device 502 can be controlled to be less than a certain preset threshold. When the second liquid storage 512 stores clean water whose concentration of cleaning liquid has been adjusted, and when the ground sensor detects that there is still oil on the ground, it can only control the operation of the second liquid delivery device 502 and use the adjusted cleaning liquid Concentrated clean water removes oil stains on the ground. When the humidity of the mop detected by the humidity detection device is greater than a preset threshold or, the first liquid reservoir 511 is controlled to output clean water at a rate lower than the current liquid discharge rate. When the user delineates an area that needs to be cleaned with the cleaning fluid multiple times on the map formed by the robot, the cleaning robot repeatedly cleans the area. When the ground sensor detects more oil in a certain area, the cleaning robot can repeatedly clean the area.

Figure 6 shows the case of a single liquid delivery device with two liquid reservoirs. The third liquid reservoir 513 is connected to the third liquid delivery device 503 through the third hose 523; the fourth liquid reservoir 514 is connected to the third liquid delivery device 503 through the fourth hose 524. In one case, only the fourth hose 524 is equipped with a first valve 531, which is opened and closed under the control of the control module to control the flow of liquid in the fourth liquid reservoir 514 to the third liquid delivery device 503. The control module selects whether to open the first valve 531 based on the current mopping requirements. For example, the third liquid reservoir 513 stores fresh water, and the fourth liquid reservoir 514 stores cleaning fluid. When the ground sensor detects that only dust exists on the ground, the control module controls the third liquid delivery device 503 to work The third liquid reservoir 513 transfers clean water to the third liquid transfer device 503 through the third hose 523. When the ground sensor detects that there is still oil on the ground, the control module controls the first valve 531 to open, thereby controlling the cleaning liquid stored in the fourth liquid reservoir 514 to flow to the third liquid delivery device 503, that is, the third liquid reservoir 513 While the clean water is transferred to the third liquid transfer device 503 through the third hose 523, the cleaning liquid is also transferred from the fourth liquid reservoir 514 to the third liquid transfer device 503 through the fourth hose 524, so that the third liquid transfer device 503 The clean water containing the cleaning liquid is sent to the mop. Because the concentration of the cleaning liquid is high, the working time of the first valve can be controlled to be less than a predetermined threshold, so as to achieve the purpose of cleaning different types of stains. In another case, a first valve 531 is installed on the fourth hose 524, and similarly to the first valve 531, a second valve (not shown) is installed on the third hose 523. The first valve 531 and the second valve are opened and closed under the control of the control module, and the liquid in the fourth liquid reservoir 514 and the third liquid reservoir 513 is controlled to flow to the third liquid delivery device 503, and the control module is based on the current mopping requirements Choose whether to open the first valve 531 and the second valve (not shown). For example, the third liquid storage 513 stores fresh water, and the fourth liquid storage 514 stores fresh water whose adjusted cleaning liquid concentration has been adjusted. When the ground sensor detects that there is only dust on the ground, the control module only controls the second valve (Not shown) Open, control the operation of the third liquid conveying device 503, and the third liquid reservoir 513 transmits clean water to the third liquid conveying device 503 through the third hose 523, and use the clean water to remove dust and the like on the ground. When the ground sensor detects that there is still oil on the ground, the control module controls the first valve 531 to open, thereby controlling the clean water stored in the fourth liquid reservoir 514 that has been adjusted to the concentration of the cleaning fluid to flow to the third liquid delivery device 503, that is, by The fourth liquid reservoir 514 transmits clean water whose concentration of the cleaning liquid is adjusted to the third liquid conveying device 503 through the fourth hose 524, and uses the liquid to mop the ground to remove oil stains and the like on the ground, so as to achieve the purpose of cleaning different types of stains.
