When the cleaning robot 100 needs to return to the base station 200, for example, when it is detected that the wiper needs to be replaced or when the cleaning robot 100 needs to be charged, the return base station 200 program is started, and the cleaning robot 100 returns to the base station 200 to complete automatic replacement of the wiper and/or automatic charging of the cleaning robot 100. In one embodiment of the present application, the wipe may be a mop or sponge wipe or the like for wiping a work surface (ground). It is worth noting that for a clearer description of the present application, the wipers are hereinafter referred to by the mop swab.
The base station 200 comprises a base plate 207, a support plate 206 and an upper plate 205, wherein the upper plate 205 is connected to the base plate 207 via the support plate 206.

Specifically, the controller can control the traveling mechanism to travel in a working area of the cleaning robot according to a preset traveling path, and the floor mopping module performs floor mopping (which may include dry mopping or wet mopping) while the traveling mechanism drives the cleaning robot to travel, so as to remove dust and other garbage in the working area. Furthermore, when the cleaning robot travels in the preset path and finishes the floor mopping work, the controller can control the cleaning robot to stop the floor mopping work and control the traveling mechanism to travel, so that the traveling mechanism drives the cleaning robot to leave the work area. The walking path and the parking position of the cleaning robot can be set in the controller in advance, and the controller controls the walking mechanism to execute.
Fig. 4 shows a case where only one liquid reservoir exists in the cleaning robot, and the cleaning robot may further include: the liquid supply device is electrically connected with the control module, and the control module can control the liquid supply device to convey liquid to the mopping module based on the current mopping condition, so that the cleaning robot can automatically control the liquid supply condition of the cleaning robot to the mop, and the conveyed liquid can be water, water added with essential oil, alcohol and the like, which is not limited in the application. As shown in fig. 4, the liquid supply device may include: the liquid conveying device 50 is electrically connected with the control module, wherein the liquid conveying device 50 is connected with the liquid storage 51. In one embodiment, the control module may be programmed to control the liquid supply to deliver liquid to the floor module, i.e., may automatically control the liquid delivery device 50 to deliver liquid from the liquid reservoir 51 to the floor module based on the current floor conditions. In another embodiment, the cleaning robot may further include a valve associated with the liquid delivery device, the valve being opened and closed under control of the control module so that the liquid supply device may be controlled to deliver liquid to the floor mopping module based on the current floor mopping condition.
In one embodiment of the present application, the liquid transfer device 50 may be a pump, and may include, but is not limited to, pump elements such as peristaltic pumps, gear pumps, plunger pumps, diaphragm pumps, etc. capable of performing a liquid transfer function, and the control module controls the amount of liquid transferred from the liquid reservoir 51 to the mopping module by controlling the rotational speed of the impeller in the pump elements. The liquid transfer device 50 is connected to the liquid reservoir 51 by a hose 52, and liquid in the liquid reservoir 51 can flow through the hose 52 to the liquid transfer device 50 so that the liquid transfer device 50 can transfer liquid to the floor module. In one embodiment of the present application, the fluid delivery device 50 may deliver fluid directly to the floor module 40 in the manner shown in FIG. 4 for the purpose of delivering fluid to the floor module. In another embodiment of the present application, the liquid delivery device 50 can directly spray the liquid to the ground during the operation of the cleaning robot, so that the cleaning robot can walk on the liquid-sprayed ground to realize wet mopping, thereby achieving the purposes of spraying the liquid to the ground to dissolve stains and mopping the ground more cleanly. It should be noted that all embodiments of the present application can use both of the above-described approaches to achieve the objective of delivering liquid to the floor mopping module.
As shown in fig. 7, in the structure of the liquid supply device of the cleaning robot according to the embodiment of the invention, after the liquid flows out from the outlet pipe 525 of the liquid delivery device 50, the liquid may be atomized by the atomizing plate 526 (in this application, 3 atomizing plates are taken as an example), and then the atomized liquid is delivered to the mopping module. In another embodiment of the present application, after the liquid exits the outlet tube of the liquid delivery device 50, it may be passed through the sponge, atomized by the atomizing plate, and delivered to the mopping module. In other embodiments, the atomization patch may be connected directly behind the liquid reservoir 51 and then delivered to the floor module. By adopting the mode, the liquid in the liquid supply device can be uniformly transmitted to the mopping module, and the mopping cloth can be uniformly covered with the liquid.
In one embodiment of the present application, the default operation mode of the cleaning robot is: the dry mopping work is executed firstly, and then the wet mopping work is executed, namely, when a user starts the cleaning robot to enter a working state, the cleaning robot can dry mopping the working area firstly, and then wet mopping the working area. Therefore, the defect that when a user does not suck dust in the working area and only uses the cleaning robot to wet and drag the working area, garbage such as hair is easily adhered to all parts of the working area can be prevented. Corresponding to the working mode of the cleaning robot, a corresponding number of dry mops and wet mops are placed on the base station, or only the dry mops are placed on the base station, and the purpose of wet mopping is realized by conveying liquid to the mopping module through the liquid supply device. And after the cleaning robot finishes the dry mopping, returning to the base station to replace a new mop, and finishing the wet mopping.
Of course, in other embodiments, the user may also change the default operating mode in the human-computer interaction of the app or the cleaning machine body according to the actual soil condition of the ground in the user's home or the user's own needs, such as changing the default operating mode to: dry mopping only, wet mopping first and dry mopping later, etc.
The floor mopping module of the cleaning robot has at least three height states in the working process: the mopping height, the obstacle crossing height and the mop unloading height can meet the requirements of mopping, obstacle crossing, automatic mop replacement and the like of the cleaning robot. The three heights are arranged from high to low and respectively comprise: the height of the unloading mop, the obstacle crossing height and the mopping height can be the same as the unloading mop, and in the application, the obstacle crossing height not only is the height of the mopping module when the cleaning robot crosses the obstacle, but also can refer to the height state when the cleaning robot mop is in a lifting state. Of course, the cleaning robot can, in addition to the three height states described above, also have a new mop installed height state below the mop height, where the uninstalled mop height can be used for uninstalling the old mop and the new mop installed height can be used for installing the new mop.
Specifically, when the cleaning robot is in a working state of mopping the floor, the control module controls the lifting mechanism to enable the mop cloth to be at the mopping height, at the moment, a certain pressure is generated between the mop cloth and the floor, and the mop cloth can be in contact with the floor and has a certain interference, so that a better cleaning effect is achieved; when the cleaning robot encounters an obstacle in the mopping process, the lifting mechanism controls the mop cloth to be at the obstacle crossing height, and at the moment, the mop cloth can be automatically lifted, the obstacle crossing height is higher than the working state height, but the obstacle crossing height cannot be higher than the unloading height, so that the mop cloth and the mopping floor are prevented from falling off; when the cleaning robot needs to return to replace the mop cloth in the mopping process or the electric quantity is lower than a preset threshold value in the mopping process and needs to return to charge, the lifting mechanism controls the mop cloth to be lifted to the obstacle crossing height to return, meanwhile, the cleaning robot can also form the position coordinate before returning through the navigation mechanism and mark the position coordinate in the working area map; when the mop cloth is replaced, the lifting mechanism controls the mop cloth to be lifted to the height of the unloaded mop cloth, and the mop board provided with the mop cloth is enabled to overcome the magnetic force to fall off from the cleaning robot through the ejector rod fixedly arranged on the cleaning robot, so that the old mop cloth is unloaded; after the old mop is unloaded, the cleaning robot can automatically install a new mop, the new mop is positioned in the new mop groove, and after the machine enters a corresponding position, the mop is descended to the height for installing the new mop, so that the new mop can be installed on the cleaning part through magnetic force, and the installation of the new mop is completed; after a new mop is installed, the lifting mechanism controls the mop to lift to the obstacle crossing height and return to the position marked in the work area map, and when the marked position is reached, the lifting mechanism controls the mop to be adjusted to the mopping height and continues mopping the floor; when the cleaning robot is required to pause mopping in the mopping process, the lifting mechanism controls the mop cloth to be lifted to the obstacle crossing height. The lifting mechanism is adopted to control the mop cloth to lift when crossing obstacles, and the defect that the cleaning range is limited due to the obstacle crossing height of almost 0 because the mop cloth of the cleaning robot only has the floor mopping height in the working process in the prior art is overcome. The mop cloth can control the lifting mechanism to lift the mop cloth to the obstacle crossing height when the mop cloth is suspended, and the defect that the floor is damaged due to the fact that the mop cloth is at the mopping height in the prior art is overcome. The cleaning robot can return to the mopping position before the mop is replaced to perform breakpoint continuous mopping after the mop is replaced, the defects that mopping is repeated on a mopped area and mopping is missed on an undrawn area in the prior art are overcome, and the cleaning efficiency of the cleaning robot is improved. Moreover, the mop can be automatically replaced, and the automation degree and the user experience of the mop robot are improved.

In the embodiment, the cleaning robot can control the liquid supplied by the liquid supply device to the floor mopping module according to the current floor mopping condition detected by at least one sensor arranged below, so that the floor mopping effect is ensured.
In an embodiment of the present application, the cleaning robot may further include: and the humidity detection device controls the liquid supply device to transmit liquid to the mopping module according to the current mopping condition detected by the humidity detection device.

In one embodiment, the humidity detection device may include: the mop humidity sensor and the control module control the liquid delivered by the liquid supply device based on the mop humidity detected by the mop humidity sensor. Preferably, the mop moisture sensor may be mounted below the fuselage, for example: a capacitive 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 humidity of the mop is greater than a preset threshold value, the liquid conveying device is controlled to output liquid at a speed lower than the current liquid outlet speed; and otherwise, when the humidity of the mop is smaller than the preset threshold value, the liquid conveying device is controlled to output the liquid at a speed higher than the current liquid output speed. The preset threshold may be set by the user according to the current ground condition, and the preset thresholds in different areas may be different.

In general, the cleaning robot may drag the floor according to a predetermined walking path. However, for some areas, when the cleaning robot detects that the floor of the area is dry, the cleaning robot may spray more liquid or increase the working time of the cleaning robot until the floor condition detected by the floor sensor meets the preset cleaning requirement, and the cleaning robot stops the cleaning work for the area; or when certain areas are detected to be relatively wet, the liquid transfer device can reduce the amount of liquid transferred or stop transferring the liquid. For example: when the cleaning robot passes through the same area in a short time, the liquid transmission device can be controlled to reduce or stop liquid supply, so that the phenomenon that liquid is wasted or wheels of the robot slip in the walking process can be avoided. In a specific application scenario, when the robot turns to and repeatedly walks to partial positions in certain areas after dragging the ground in the certain areas, if liquid supply is continued, excessive liquid on the ground is caused to cause the machine to skid or waste the liquid, so that when the robot is detected to repeatedly walk in the same area in a short time, the liquid conveying device can be controlled to stop supplying the liquid.

Specifically, the ground state may include: ground materials, and the like. The floor sensor may detect a material of the work surface, such as a floor or tile, and the control module may control the amount of liquid delivered by the liquid delivery device to the mopping module based on a condition of the floor detected by the floor sensor.

When receiving the notification message, the user can choose not to respond, can control the cleaning robot to pause working, can choose to reduce the liquid outlet rate, or choose to add liquid to the cleaning robot.
In another embodiment, the cleaning robot may further include: indicating means, for example: a light emitting indicator (LED, etc.) or a sound emitting indicator, which may be used to indicate whether the cleaning robot liquid amount is sufficient. The indicating device is different in the state when the liquid amount is not lower than the preset threshold value and the state when the liquid amount is lower than the preset threshold value, and a user monitors the liquid level condition in the liquid storage device by observing different states of the indicating device.

The ground state may include: floor material and/or floor stain type. The floor sensor can control the amount of liquid that the two liquid reservoirs deliver to the mop, respectively, based on the detected condition of the floor material, whether the floor soil is greasy or dirty, wherein the amount of liquid delivered can be 0, i.e. it can be controlled that only one of the liquid reservoirs is used. In general, the cleaning robot may drag the floor according to a predetermined walking path. However, for some areas, when the cleaning robot detects that the floor of the area is dry and greasy, the cleaning robot may spray more liquid or increase the working time of the cleaning robot until the floor condition detected by the floor sensor meets the preset cleaning requirement, and the cleaning robot stops cleaning the area. In this embodiment, the two liquid reservoirs may be controlled to deliver liquid to the mopping module, respectively, until the floor condition detected by the floor sensor meets a predetermined cleaning requirement, and the cleaning robot stops cleaning work for this area.

In the following, a description is given of specific embodiments with two liquid reservoirs.
Both as shown in fig. 5 and 6 are situations where two liquid reservoirs are present. It should be noted that the terms "first" and "second" in the present application are used for distinguishing the two devices as different devices, and do not have other special meanings, such as: hereinafter, the first hose and the second hose are both hoses, but two different hoses. Meanwhile, in the present application, only two liquid reservoirs are taken as an example for explanation, and more than two liquid reservoirs may be used, which have the same principle and are not described in detail in the present application.
Fig. 5 shows a dual liquid transfer device dual liquid reservoir. The first liquid storage 511 is connected with the first liquid conveying device 501 through a first hose 521, the second liquid storage 512 is connected with the second liquid conveying device 502 through a second hose 522, the first liquid conveying device 501 and the second liquid conveying device 502 are respectively and electrically connected with a control module, the control module can select the first liquid conveying device 501 or the second liquid conveying device 502 to convey liquid to the mop cloth simultaneously or respectively based on the current mopping requirement, and also can select the liquid amount conveyed to the mop cloth simultaneously or respectively by the first liquid conveying device 501 or the second liquid conveying device 502, so as to ensure the mopping effect. For example, the first liquid storage 511 is filled with clean water, the second liquid storage 512 is filled with cleaning liquid, and when the floor sensor detects that only dust is on the floor, the control module controls the first liquid transfer device 501 to operate, and the first liquid storage 511 transfers the clean water to the first liquid transfer device 501 through the first hose 521, so that the first liquid transfer device 501 transfers the clean water to the mop, and the clean water is used to remove the dust and the like on the floor. When the floor sensor detects that there is oil on the floor, the control module controls the first liquid transferring device 501 to operate and also controls the second liquid transferring device 502 to operate, that is, while the first liquid storage 511 transfers clean water to the first liquid transferring device 501 through the first hose 521, the second liquid storage 512 transfers cleaning liquid to the second liquid transferring device 502 through the second hose 522 so that the second liquid transferring device 502 transfers cleaning liquid to the mop, because the concentration of the cleaning liquid is high, the operating time of the second liquid transferring device 502 can be controlled to be less than a preset threshold. When the second liquid storage 512 stores clean water with adjusted concentration of the cleaning liquid, and the ground sensor detects that there is oil on the ground, it is possible to control only the second liquid transfer device 502 to operate, and clean the oil on the ground with the clean water with adjusted concentration of the cleaning liquid. When the mop humidity detected by the humidity detection means is greater than a preset threshold or, the first liquid reservoir 511 is controlled to output fresh water at a rate lower than the current tapping rate.

In one case, only the fourth hose 524 has the first valve 531 mounted thereon, the first valve 531 opening and closing under the control of the control module, which selects whether to open the first valve 531 based on the current mopping requirement, to control the flow of liquid from the fourth liquid reservoir 514 to the third liquid transfer device 503. For example, the third liquid storage 513 stores clean water, the fourth liquid storage 514 stores cleaning liquid, and when the floor sensor detects that only dust is present on the floor, the control module controls the third liquid transfer device 503 to operate, and the third liquid storage 513 transfers the clean water to the third liquid transfer device 503 through the third hose 523. When the floor sensor detects that there is oil on the floor, the control module controls the first valve 531 to open, so as to control the cleaning liquid stored in the fourth liquid storage 514 to flow to the third liquid delivery device 503, that is, while the third liquid storage 513 delivers clean water to the third liquid delivery device 503 through the third hose 523, the fourth liquid storage 514 delivers cleaning liquid to the third liquid delivery device 503 through the fourth hose 524, so that the third liquid delivery device 503 delivers clean water containing cleaning liquid to the mop, and because the concentration of the cleaning liquid is high, the working time of the first valve can be controlled to be less than a preset threshold, so as to achieve the purpose of cleaning different types of stains. In another case, the fourth hose 524 is provided with a first valve 531, and the third hose 523 is provided with a second valve (not shown) similar to the first valve 531. 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 storage 514 and the third liquid storage 513 is controlled to flow to the third liquid transfer device 503, and the control module selects whether to open the first valve 531 and the second valve (not shown) based on the current floor mopping requirement. For example, the third liquid storage 513 stores clean water, the fourth liquid storage 514 stores clean water with adjusted concentration of cleaning liquid, and when the ground sensor detects that only dust exists on the ground, the control module only controls the second valve (not shown) to open, controls the third liquid transfer device 503 to operate, and transfers clean water from the third liquid storage 513 to the third liquid transfer device 503 through the third hose 523, and removes dust on the ground by using the clean water. When the ground sensor detects that there is oil stain on the ground, the control module controls the first valve 531 to open, so as to control the clear water stored in the fourth liquid storage 514 and having the adjusted concentration of the cleaning liquid to flow to the third liquid delivery device 503, that is, the clear water having the adjusted concentration of the cleaning liquid is delivered from the fourth liquid storage 514 to the third liquid delivery device 503 through the fourth hose 524, and the liquid is used for mopping the ground to remove the oil stain and the like on the ground, thereby achieving the purpose of cleaning different types of stains.
