[0074] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The present invention proposes a base station 30 for pumping sewage and injecting water into a cleaning robot 10 . The cleaning robot 10 is formed with a main body sewage collecting chamber 111 and a main body clean water chamber 112 .

[0075] In one embodiment of the present invention, the base station 30 includes a base station body 31, a sewage extraction component 33, and a water injection component 35. The sewage extraction component 33 is disposed on the base station body 31, and can move relative to the base station body 31 to be connected to the main machine sewage collection chamber 111; the water injection component 35 is disposed on the base station body 31, and can move relative to the base station body 31 to be connected to the main machine clean water chamber 112.

[0076] In one embodiment of the present invention, the cleaning robot 10 may include a robot body 11, which can be used to install and carry various parts of the cleaning robot 10 (such as a cleaning brush 13, a moving wheel 15, a motor that drives the moving wheel 15 to rotate, and a main blower for connecting with the main machine dirt collection chamber 111 so that the dirt collection port of the main machine dirt collection chamber 111 generates suction to absorb garbage and sewage on the ground, etc.), so that the various parts of the cleaning robot 10 can be assembled into a whole. Among them, the projection of the robot body 11 on the horizontal plane can be roughly circular, so that the side circumference of the main machine has consistency, and then it can move more smoothly when turning at a corner or an obstacle. At the same time, such a setting can also make the shape of the robot body 11 more regular and easy to shape and manufacture. Of course, the present application is not limited to this. In other embodiments, the projection of the robot body 11 on the horizontal plane can also be a square or a rectangle. The host dirt collection chamber 111 formed in the robot body 11 can be used to collect the garbage and sewage adsorbed by the cleaning robot 10 when cleaning the ground. Specifically, the host fan in the robot body 11 is connected to the host dirt collection chamber 111. The host dirt collection chamber 111 is exhausted by the host fan, so that a negative pressure is formed in the host dirt collection chamber 111, thereby sucking the garbage and sewage on the ground into the host dirt collection chamber 111 for storage and collection. Since the cleaning robot 10 realizes the adsorption and collection of garbage and sewage on the ground by exhausting the dirt collection chamber by the host fan to form a negative pressure, it is not described in detail here. Among them, the host dirt collection chamber 111 can be directly opened on the host, or a host dirt collection box can be additionally embedded on the host, and the host dirt collection chamber 111 is formed in the host dirt collection box. The present application does not limit the specific formation and shape of the host dirt collection chamber 111, and it can realize the storage and collection of garbage and sewage adsorbed by the cleaning robot 10 when working. The main engine clean water chamber 112 can be used to store a certain amount of clean water, so that the cleaning robot 10 can spray water to clean the ground during cleaning, which is beneficial to improve the cleaning effect of the cleaning robot 10 on the ground. Among them, the main engine clean water chamber 112 can be directly opened and formed on the main engine, or a main engine clean water tank can be additionally embedded on the main engine, and the main engine clean water chamber 112 is formed in the main engine clean water tank. The present application does not limit the specific formation and shape of the main engine clean water chamber 112, and it can be achieved that a certain amount of clean water can be stored for the cleaning robot 10 to wash the ground when working. The water spray of the cleaning robot 10 can be provided with a main engine nozzle 11g on the robot body 11, and the main engine nozzle 11g is connected to the main engine clean water chamber 112, and can spray water toward the ground or the cleaning brush 13 of the cleaning robot 10.The base station body 31 of the base station 30 can be used to install and carry various parts of the base station 30 (for example: sewage extraction component 33 and water injection component 35, and base station 30 controller, etc.), so that the various parts of the base station 30 can be assembled into a whole. Among them, the base station body 31 can be roughly arranged in a rectangular parallelepiped, so that the shape of the base station body 31 is relatively regular and convenient for molding and manufacturing. Further, the length direction of the base station body 31 can be parallel to the up and down direction, so that the projection of the base station body 31 on the horizontal plane can be relatively small, thereby reducing its occupation of space on the ground. Of course, the present application is not limited to this. In other embodiments, the base station body 31 can also be arranged in a roughly square or cylindrical shape. In one embodiment, please refer to it. Figure 2 and Figure 7, the base station body 31 can be formed with a base station dirt collection chamber 31a and a base station clean water chamber 31b, at which time the sewage extraction component 33 is connected to the base station dirt collection chamber 31a, and the water injection component 35 is connected to the base station clean water chamber 31b. Among them, the base station dirt collection chamber 31a can be directly opened and formed on the base station body 31, or a base station dirt collection box 301 can be additionally embedded on the base station body 31, and the base station dirt collection chamber 31a is formed in the base station dirt collection box 301. The present application does not limit the specific formation and shape of the base station dirt collection chamber 31a, and can realize the collection of garbage and sewage extracted by the sewage extraction component 33 from the host dirt collection chamber 111. The base station clean water chamber 31b can be used to store relatively more clean water, and when the cleaning robot 10 and the base station 30 are docked, the clean water in the base station clean water chamber 31b is transferred to the host clean water chamber 112 through the water injection component 35 to realize the replenishment of the clean water in the host clean water chamber 112. The base station clean water chamber 31b may be formed by directly opening on the base station body 31, or the base station body 31 may be additionally embedded with a base station clean water tank 303, and the base station clean water chamber 31b is formed in the base station clean water tank 303. The present application does not limit the specific formation and shape of the base station clean water chamber 31b, as long as it can store relatively more clean water. Furthermore, the base station clean water chamber 31b may be connected to a water inlet pipe, so that after the base station clean water chamber 31b replenishes clean water to the host clean water chamber 112 for multiple times, the base station clean water chamber 31b can be automatically filled with water by opening the water inlet pipe, thereby facilitating the use of the base station 30. In order to improve the cleaning effect on the ground, in one embodiment of the present invention, the base station body 31 may also be provided with a cleaning liquid chamber, and the water injection assembly 35 is connected to the cleaning liquid chamber. At this time, the cleaning liquid is stored in the cleaning liquid chamber, and when the cleaning robot 10 moves to the base station 30 for docking, the water injection assembly 35 is used to add water to the main unit clean water chamber 31b, and the cleaning liquid in the cleaning liquid chamber is transported to the main unit clean water chamber 31b. In this way, when the cleaning robot 10 subsequently cleans the ground, the cleaning water with cleaning liquid can be sprayed out through the main unit nozzle 11g, thereby achieving better cleaning of the ground. Among them, the cleaning liquid chamber can be directly opened and formed on the base station body 31, or a cleaning liquid storage box can be additionally embedded on the base station body 31, and a cleaning liquid chamber is formed in the cleaning liquid storage box. Of course, it should be noted that the present application is not limited to this. In other embodiments, when the base station body 31 is not formed with the base station sewage collection chamber 31a and the base station clean water chamber 31b, the sewage extraction assembly 33 can include a collection box, and the water injection assembly 35 can include a water storage tank, so that the garbage and sewage extracted by the sewage extraction assembly 33 can be collected through the collection box, and the clean water can be stored through the water storage tank. The sewage extraction component 33 can be used to generate suction and extract garbage and sewage in the main unit sewage collection chamber 111. The sewage extraction component 33 can include a sewage extraction fan, that is, the sewage collection chamber 111 of the main unit is evacuated by the sewage extraction fan.In addition, when the sewage extraction component 33 extracts sewage from the main engine sewage collection chamber 111, the main engine fan connected to the main engine sewage collection chamber 111 needs to be turned off so that only the sewage extraction airflow direction from the main engine sewage collection chamber 111 to the sewage extraction fan is formed. The water injection component 35 can be used to inject water into the main engine clean water chamber 112 to replenish it with clean water. Among them, when the position of the base station clean water chamber 31b is set or the position of the water storage tank of the water injection component 35 is relatively high, the water injection component 35 can drop clean water into the main engine clean water chamber 112 through the action of gravitational potential energy. When the position of the base station clean water chamber 31b is set or the position of the water storage tank of the water injection component 35 is relatively low, the water injection component 35 may include a water pump, that is, the water pump provides power to extract the clean water in the base station clean water chamber 31b or the clean water in the water storage tank on the water injection component 35 into the main engine clean water chamber 112.

[0077] When the base station 30 of the technical solution of the present invention is in use, the sewage extraction component 33 and the water injection component 35 are driven to approach the cleaning robot 10, so that the sewage extraction component 33 is connected to the main machine sewage collection chamber 111 of the cleaning robot 10, and the water injection component 35 is connected to the main machine clean water chamber 112 of the cleaning robot 10. At this time, the sewage extraction component 33 can suck the main machine sewage collection chamber 111 on the cleaning robot 10, thereby realizing the extraction of garbage and sewage in the main machine sewage collection chamber 111. And the water injection component 35 can inject water into the clean water chamber on the cleaning robot 10, thereby realizing the replenishment of clean water in the main machine clean water chamber 112.

[0078] Therefore, after docking with the cleaning robot 10, the base station 30 in the present technical solution can extract the garbage stored in the cleaning robot 10 and replenish the clean water in the main unit clean water chamber 112. Compared with the prior art, the base station 30 can only collect the garbage stored in the cleaning robot 10, resulting in the need for the user to manually replenish the main unit clean water chamber 112 of the cleaning robot 10 after use. The base station 30 in the present technical solution has more diverse functions, and does not require the user to manually replenish the main unit clean water chamber 112 of the cleaning robot 10, thereby improving the practicality of the base station 30.

[0079] Furthermore, the sewage extraction component 33 and the water injection component 35 in the present technical solution are both movably arranged on the base station body 31, so that before the cleaning robot 10 and the base station 30 are moved into place during the docking process, the sewage extraction component 33 and the water injection component 35 can be at a certain distance from the cleaning robot 10, and only after the cleaning robot 10 is moved into place, it moves close to the cleaning robot 10 to extract sewage (extract the garbage stored by the cleaning robot 10) and inject water (replenish the clean water in the clean water chamber 112 of the host). In this way, the cleaning robot 10 is prevented from colliding with the sewage extraction component 33 and the water injection component 35 on the base station 30 during the process of moving close to the base station 30 for docking, thereby reducing the possibility of damage to the cleaning robot 10, the sewage extraction component 33 and the water injection component 35 due to collision.

[0080] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, the sewage extraction component 33 and the water injection component 35 are both liftably arranged on the base station body 31. The sewage extraction component 33 and the water injection component 35 are lowered relative to the base station body 31 to be connected to the main machine sewage collecting chamber 111 and the main machine clean water chamber 112 respectively.

[0081] It can be understood that the sewage extraction component 33 and the water injection component 35 are arranged on the base station body 31 in a liftable manner (it can be that only the end of the sewage extraction component 33 and the water injection component 35 used for docking with the cleaning robot 10 can be lifted relative to the base station body 31, of course, the sewage extraction component 33 and the water injection component 35 can be lifted relative to the base station body 31 as a whole, and the end of the sewage extraction component 33 and the water injection component 35 away from the end used for docking with the cleaning robot 10 can be connected with a flexible tube), so that the movement of the sewage extraction component 33 and the water injection component 35 is in the up and down direction. In this way, there is no need to set a relatively large avoidance space in the horizontal direction for the movement of the sewage extraction component 33 and the water injection component 35, so that the projection area of ​​the base station body 31 on the horizontal plane can be set relatively small, that is, the space occupied by the base station body 31 on the ground is reduced and the convenience of its placement is improved. Of course, the present application is not limited to this. In other embodiments, the sewage extraction component 33 and the water injection component 35 can also be slidable or rotatable in the horizontal direction on the base station body 31, and can be connected with the host sewage collection chamber 111 and the host clean water chamber 112 after sliding or rotating.

[0082] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, the base station 30 further includes a driving member 37, which is disposed on the base station body 31 and connected to the sewage extraction assembly 33 and the sewage extraction assembly 33. The driving member 37 drives the sewage extraction assembly 33 and the water injection assembly 35 to rise and fall relative to the base station body 31.

[0083] It can be understood that the sewage extraction component 33 and the water injection component 35 are driven to rise and fall by the driving member 37, so as to realize the automatic docking of the sewage extraction component 33 with the main engine sewage collection chamber 111 and the water injection component 35 with the main engine clean water chamber 112, thereby improving the degree of automation of the docking of the cleaning robot 10 and the base station 30, and further improving the convenience of the use of the cleaning system 100. Moreover, the sewage extraction component 33 and the water injection component 35 are driven to rise and fall by a driving member 37 at the same time, so that the number of driving members 37 is set smaller, thereby reducing the manufacturing cost of the cleaning system 100. At the same time, the sewage extraction component 33 and the water injection component 35 are connected to a driving member 37, so that the distribution of the several can be more compact, which is conducive to reducing the occupation of space. Of course, the driving member 37 can also be provided with two, and the two driving members 37 are both arranged on the base station body 31. One of the two driving members 37 can be connected to the sewage extraction component 33, and the other driving member 37 can be connected to the water injection component 35. At this time, the sewage extraction assembly 33 and the water injection assembly 35 can be driven to rise and fall respectively by two driving members 37. In addition, it should be noted that the present application is not limited thereto. In other embodiments, a pull rod slidable in the up and down direction is provided on the base station body 31 of the base station 30, and the sewage extraction assembly 33 and the water injection assembly 35 are connected to one end of the pull rod. At this time, it is also possible for the user to manually drive the pull rod away from one end of the sewage extraction assembly 33 and the water injection assembly 35 so that the sewage extraction assembly 33 and the water injection assembly 35 can be lifted and lowered. In addition, in one embodiment, the base station body 31 is also provided with a button and / or a display screen. At this time, the button can be used for the user to input corresponding operation instructions, so as to more conveniently control the base station 30 to perform corresponding work, such as: the suspension of the start of the base station 30, the sewage extraction rate adjustment of the sewage extraction assembly 33, the water injection rate adjustment of the water injection assembly 55, or some other control instructions. The display screen can display the working status of the base station 30 to the user (for example, the amount of clean water remaining in the clean water chamber 303 of the base station, the amount of garbage and sewage collected in the base station sewage chamber 31a, the amount of clean liquid remaining in the clean liquid chamber, and other working statuses), so that the user can more intuitively understand the working status of the base station 30. Furthermore, the display screen can be a touch screen, so that the user can input some instructions on the display screen.

[0084] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, the sewage extraction component 33 includes a sewage extraction pipe 331, which is used to connect to the main unit sewage collecting chamber 111, and the water injection component 35 includes a water injection pipe 351, which is used to connect to the main unit clean water chamber 112; the driving member 37 is connected to the sewage extraction pipe 331 and the water injection pipe 351, and drives the sewage extraction pipe 331 and the water injection pipe 351 to rise and fall relative to the base station body 31.

[0085] It can be understood that the driving member 37 only drives the sewage extraction pipe 331 and the water injection pipe 351 to rise and fall. Since the weight of the sewage extraction pipe 331 and the water injection pipe 351 is relatively light, the load on the driving member 37 can be reduced, which makes it easier for the driving member 37 to drive them. Of course, the present application is not limited to this. In other embodiments, the driving member 37 can be a sewage extraction pipe 331 of the sewage extraction assembly 33 and a sewage extraction fan connected to the sewage extraction pipe 331 to provide sewage extraction power to move as a whole. Similarly, the driving member 37 can also drive the water injection pipe 351 of the water injection assembly 35 and a water pump connected to the water injection pipe 351 to provide water injection power to move as a whole. In addition, when the base station body 31 is provided with a clean liquid cavity, the upstream of the water injection pipe 351 is connected to the clean liquid cavity.

[0086] Please refer to Figure 3 In one embodiment of the present invention, the base station 30 also includes a transmission component 39, which is connected to the driving member 37, the sewage extraction pipe 331 and the water injection pipe 351 are connected to the transmission component 39, and the driving member 31 drives the sewage extraction pipe 331 and the water injection pipe 351 to rise and fall through the transmission component 39.

[0087] It can be understood that the rotational motion of the output shaft of the driving member 37 can be converted into linear motion by the transmission assembly 39, so as to realize driving the sewage extraction pipe 331 and the water injection pipe 351 to be lifted and lowered relative to the base station body 31. That is, at this time, the driving member 37 can be a motor, and the transmission assembly 39 can also avoid the motor rotating too fast to affect the stability of the sewage extraction pipe 331 and the water injection pipe 351 during the lifting process, thereby further helping to reduce the possibility of collision between the sewage extraction pipe 331 and the water injection pipe 351 during the docking process between the cleaning robot 10 and the base station 30. Of course, it should be noted that the present application is not limited to this. In other embodiments, the driving member 37 directly adopts a cylinder, and the sewage extraction pipe 331 and the water injection pipe 351 are directly connected to the telescopic end of the cylinder. At this time, it is also possible to directly drive the sewage extraction pipe 331 and the water injection pipe 351 to lift and lower by the cylinder.

[0088] In one embodiment of the present invention, the transmission assembly 39 includes a gear 391 and a rack 393, and the gear 391 is sleeved on the output shaft of the driving member 37; the rack 393 is liftably arranged on the base station body 31 and meshes with the gear 391, and the sewage extraction pipe 331 and the water injection pipe 351 are connected to the rack 393.

[0089] It can be understood that when the transmission assembly 39 is composed of a gear 391 and a rack 393, since the gear 391 and the rack 393 transmission have the advantages of large bearing capacity and high precision, the sewage pumping pipe 331 and the water injection pipe 351 can be stably loaded, and the stability of the driving sewage pumping pipe 331 and the water injection pipe 351 during the lifting process can be ensured. Among them, in order to facilitate the connection of the rack 393 with the sewage pumping pipe 331 and the water injection pipe 351, the rack 393 can be connected to a mounting plate, and the mounting plate is provided with two mounting holes, and the sewage pumping pipe 331 and the water injection pipe 351 are respectively inserted in the two mounting holes. Of course, the sewage pumping pipe 331 and the water injection pipe 351 can also be connected to the rack 393 through a hoop. In addition, it should be noted that the present application is not limited to this. In other embodiments, the transmission assembly 39 can also include a screw and a slide seat, and the screw can be rotatably arranged on the base station body 31, and is extended along the lifting direction of the sewage pumping pipe 331 and the water injection pipe 351. The slide seat is escalably mounted on the outer side of the screw rod and connected to the sewage extraction pipe 331 and the water injection pipe 351. Alternatively, the transmission assembly 39 includes a driving wheel, a driven wheel and a belt, wherein the driving wheel is mounted on the output shaft of the driving member 37, the driven wheel is rotatably mounted on the base station body 31, and the belt is mounted on the driving wheel and the driven wheel. In this case, the sewage extraction pipe 331 and the water injection pipe 351 can be connected to the belt.

[0090] Please refer to Figure 3 In one embodiment of the present invention, a side wall of the base station body 31 (having a top wall and a bottom wall, and a side wall connecting the top wall and the bottom wall when the base station 30 is in normal use) is recessed to form a docking groove 31d, and the docking groove 31d is used to accommodate the cleaning robot 10; an installation cavity 31f is also formed in the base station body 31, and a cavity bottom wall of the installation cavity 31f is provided with a clearance hole 31g connected to the docking groove 31d; the driving member 37, the sewage extraction pipe 331 and the water injection pipe 351 are all arranged in the installation cavity 31f, and the sewage extraction pipe 331 and the water injection pipe 351 can extend into the docking groove 31d through the clearance hole 31g when they are driven down by the driven member 37.

[0091] It can be understood that the docking groove 31d is used to accommodate the cleaning robot 10 and the base station 30 when docking, so that the cleaning robot 10 and the base station 30 can be distributed more compactly when docking, thereby reducing the space occupied. At the same time, the groove wall of the docking groove 31d can also play a certain limiting and guiding role for the cleaning robot 10, so as to help ensure the accurate docking of the cleaning robot 10 and the base station 30. At the same time, the driving member 37, the sewage extraction pipe 331 and the water injection pipe 351 are all arranged in the installation cavity 31f, and the cavity wall of the installation cavity 31f can play a certain protective role for the driving member 37, the sewage extraction pipe 331 and the water injection pipe 351, reducing the possibility of damage by foreign objects. Among them, the installation cavity 31f can be roughly a square structure, so that its shape is more regular and easy to form and manufacture. The shape of the docking groove 31d can be an arch shape, so as to adapt to the circular cleaning robot 10. Of course, it can also be square-shaped. The present application does not limit the specific shape of the docking groove 31d, as long as it can accommodate the cleaning robot 10. Moreover, the docking groove 31d can be a part of the cleaning robot 10, or it can be the whole of the cleaning robot 10. The docking groove 31d can specifically include a groove top wall, a groove bottom wall arranged opposite to the groove top wall, and a groove side wall connecting the groove top wall and the groove bottom wall. The groove top wall, the groove bottom wall, and the groove side wall of the docking groove 31d are formed with a notch on the same plane or on different planes. For example, in order to make the groove bottom wall support the cleaning robot 10 more completely, the pair of groove bottom walls can be prominent on the groove top wall and the groove side wall. In addition, it should be noted that the present application is not limited to this. In other embodiments, a bottom plate is convexly provided near the bottom of the side wall of the base station body 31, and the bottom plate can also support the cleaning robot 10 when the cleaning robot 10 and the base station 30 are docked.

[0092] In one embodiment of the present invention, a travel limiting mechanism is provided in the installation cavity 31 f , and the travel limiting mechanism can limit the lifting and lowering travel of the sewage extraction pipe 331 and the water injection pipe 351 driven by the driving member 37 .

[0093] It can be understood that the travel limit mechanism can reduce the possibility of collision with other objects when the driving member 37 drives the sewage extraction pipe 331 and the water injection pipe 351 to rise and fall, thereby improving the safety of the sewage extraction pipe 331 and the water injection pipe 351 during the lifting process. Among them, the travel limit mechanism controls the driving member 37 through a controller arranged on the base station body 31. For example, when the driving member 37 is a motor, the number of rotations of the motor can be controlled by the controller. Of course, the base station 30 can also be provided with a limit switch to form a travel limit mechanism, such as a touch switch or a proximity switch. When the rack 393 of the transmission assembly 39 rises and falls to contact the touch switch and trigger the in-place signal, or approaches the proximity switch and triggers the in-place signal, the motor stops driving the gear 391 to rotate.

[0094] In one embodiment of the present invention, a position sensor is disposed in the docking slot 31 d . The position sensor is electrically connected to the driving member 37 . The position sensor can detect whether the cleaning robot 10 is in place in the docking slot 31 d .

[0095] It can be understood that the in-place sensor can detect whether the cleaning robot 10 has moved into position in the docking slot 31d, that is, has reached the preset docking position. After that, the in-place signal of the cleaning robot 10 can be transmitted to the driving member 37, and the driving member 37 can be started according to the in-place signal to drive the sewage extraction pipe 331 and the water injection pipe 351 to descend. In this way, after the cleaning robot 10 moves into position, the sewage extraction pipe 331 and the water injection pipe 351 can be promptly lowered to communicate with the main machine sewage collection chamber 111 and the main machine clean water chamber 112, thereby helping to improve the sewage extraction and water injection efficiency. At the same time, the automation level of the base station 30 is further improved, and there is no need to manually control the operation of the driving member 37.

[0096] Please refer to Figure 6 In one embodiment of the present invention, a charging electrode 311 is provided on the groove wall of the docking groove 31d, and the charging electrode 311 is formed as an in-position sensor. The charging electrode 311 is electrically connected to the driving member 37; when the cleaning robot 10 moves into the docking groove 31d, the charging electrode 311 abuts against the charging contact 113 on the robot body 11.

[0097] It can be understood that the contact between the charging contact 113 and the charging electrode 311 realizes the transmission of the cleaning robot 10 moving into position signal to the driving member 37. In addition to realizing the automatic operation of the driving member 37, the base station 30 further enables the cleaning robot 10 to be charged, that is, the use function of the base station 30 is further enhanced, and the cleaning robot 10 is automatically charged without the user manually moving the cleaning robot 10 to the charging place for charging. Among them, the charging electrode 311 can be arranged on the side wall of the docking groove 31d, or on the top wall or bottom wall of the docking groove 31d; the charging electrode 311 can also be arranged on the side wall, upper surface or lower surface of the robot body 11.

[0098] Please refer to Figure 1 , Figure 2 , Figure 6 as well as Figure 7 In one embodiment of the present invention, a guide structure 313 is provided on the groove wall of the docking groove 31d, and the guide structure 313 can guide the cleaning robot 10 to move into the docking groove 31d.

[0099] It can be understood that the guide structure 313 can guide the cleaning robot 10 to move into the docking slot 31d so that the cleaning robot 10 moves to an accurate position in the docking slot 31d for positioning. This also facilitates the accurate contact driving of the push rod 312 on the pressing seat 117, avoiding the misalignment of the push rod 312 with the pressing seat 117, which causes the push rod 312 to collide with other structures of the cleaning robot 10 and damage the cleaning robot 10.

[0100] Please refer to Figure 7 In one embodiment of the present invention, the guide structure 313 includes a guide groove 313a, which is arranged on the bottom wall of the docking groove 31d and extends along the groove side wall of the docking groove 31d facing its groove opening to the groove opening of the docking groove 31d. The guide groove 313a also penetrates the surface of the base station body 31 to form the groove opening of the docking groove 31d. The guide groove 313a is used to accommodate the moving wheel 15 of the cleaning robot 10.

[0101] It can be understood that since the cleaning robot 10 is provided with a moving wheel 15, a guide groove 313a for accommodating and guiding the moving wheel 15 is provided on the bottom wall of the docking groove 31d to form a guide structure 313, which can simplify the structure of the guide structure 313. At the same time, it is unnecessary to provide an additional structure on the cleaning robot 10 to form the guide structure 313, which is also conducive to simplifying the structure of the cleaning robot 10.

[0102] Please refer to Figure 7In one embodiment of the present invention, the guide groove 313a includes a guide groove section 313b and a limiting groove section. The guide groove section 313b is arranged close to the notch of the docking groove 31d and penetrates the surface of the notch of the docking groove 31d formed on the robot body 11. In the direction from the groove side wall of the docking groove 31d facing the notch to the notch of the docking groove 31d, the distance between the two opposite groove side walls of the guide groove section 313b is gradually increased; the limiting groove section is connected to one end of the guide groove section 313b away from the notch of the docking groove 31d. In the direction from the groove side wall of the docking groove 31d facing the notch to the notch of the docking groove 31d, the distance between the two opposite groove side walls of the limiting groove section is equal.

[0103] It can be understood that the guide groove section 313b of the guide groove 313a can guide the moving wheel 15 to gradually and accurately move into the limiting groove section, thereby reducing the alignment accuracy requirements of the moving wheel 15 and the limiting groove section, so as to facilitate the accurate alignment of the cleaning robot 10 and the base station 30. The limiting groove section of the guide groove 313a can limit the moving wheel 15, so that the moving wheel 15 can only be extended along the moving direction of the limiting groove section, so as to facilitate the subsequent accurate alignment with the base station 30 (for example: the abutment alignment of the charging electrode 311 and the charging contact 113). Among them, the distance between the two opposite groove side walls of the limiting groove section can be set to be equivalent to the thickness of the moving wheel 15 of the cleaning robot 10, so that when the moving wheel 15 moves into the limiting groove section, the two opposite groove side walls of the limiting groove section can abut against the two corresponding side wall surfaces of the moving wheel 15. Of course, the distance between the two opposite groove side walls of the limiting groove section can also be greater than the wheel width of the moving wheel 15. In this case, the two adjacent groove side walls of the two limiting groove sections can be distributed to abut the facing surfaces of the two moving wheels 15. In addition, it should be noted that in other embodiments, it is also possible for the guide groove 313a to have only the limiting groove section. Alternatively, it is also possible for the guide groove 313a to have only the guide groove section 313b. In this case, the minimum distance between the two opposite groove side walls of the guide groove 313a can be the same as the thickness of the moving wheel 15.

[0104] Please refer to Figure 1 and Fig.12In one embodiment of the present invention, the number of the moving wheels 15 of the cleaning robot 10 is three, and two of the three moving wheels 15 are defined as driving wheels 151, and the other is a universal wheel 153; when the cleaning robot 10 moves into the docking groove 31d, the two driving wheels 151 are relatively spaced apart on the robot body 11 in the direction from the groove side wall perpendicular to the groove opening of the docking groove 31d to the groove opening of the docking groove 31d, and the universal wheel 153 is located on the side of the two driving wheels 151 away from the groove bottom of the docking groove 31d, and is distributed in a triangular shape on the main machine with the two universal wheels 153; the number of the guide grooves 313a is three, and the three guide grooves 313a are arranged in a one-to-one correspondence with the two driving wheels 151 and one universal wheel 153.

[0105] It can be understood that the two driving wheels 151 and one universal wheel 153 are distributed in a triangular shape, which can provide relatively stable support for the robot body 11 when the number of mobile wheels 15 is relatively small, which is conducive to reducing the manufacturing cost of the cleaning robot 10. The two driving wheels 151 can provide a relatively driving force to drive the cleaning robot 10 to move. The universal wheel 153 can make the cleaning robot 10 adjust the steering more smoothly during the movement process, which is conducive to improving the docking efficiency of the cleaning robot 10 in the docking groove 31d. Of course, the present application is not limited to this. In other embodiments, the number of the mobile wheels 15 can also be four or more. Among them, the number of driving wheels 151 and universal wheels 153 can be adaptively configured as needed. Alternatively, it is also possible for the mobile wheel 15 to consist only of a driving wheel 151 and an ordinary one-way wheel.

[0106] Please refer to Figure 6 In one embodiment of the present invention, the guide structure 313 also includes a roller 315, and at least one of the two opposite groove side walls of the docking groove 31d is provided with a roller 315; the roller 315 can rotate relative to the base station body 31 around a direction perpendicular to the groove side wall of the docking groove 31d facing its groove opening to the groove opening of the docking groove 31d, and the roller 315 is used to abut against the side wall of the cleaning robot 10 moved into the docking groove 31d.

[0107] It can be understood that when the cleaning robot 10 moves to the docking groove 31d for docking, the roller 315 can be used to abut the side wall of the cleaning robot 10 to limit the position, so as to guide the cleaning robot 10 to accurately move to the preset docking position. Among them, one of the two opposite groove side walls of the docking groove 31d can be provided with a roller 315, or both groove side walls can be provided with a roller 315. In addition, in one embodiment, after the groove bottom wall of the docking groove 31d is provided with a guide groove 313a, the two opposite groove side walls of the docking groove 31d are further provided with a roller 315, that is, the setting of the guide groove 313a and the setting of the roller 315 are used in combination.

[0108] Please refer to Figure 6 In one embodiment of the present invention, the guide structure 313 further includes an infrared transmitter 317, and the infrared transmitter 317 is disposed on the base station body 31. In this case, the cleaning robot 10 may be provided with an infrared receiver.

[0109] It can be understood that the cleaning robot 10 will move to various positions when cleaning the ground. Therefore, the infrared receiver on the cleaning robot 10 receives the infrared signal emitted by the infrared transmitter 317 on the base station body 31, so as to achieve preliminary positioning of the base station 30, thereby facilitating rapid approach to the base station 30 and accurate docking with the base station 30 after precise positioning through the guide groove and / or the roller 315. That is, after the guide groove 313a is provided on the bottom wall of the docking groove 31d and / or the rollers 315 are provided on the two opposite groove side walls of the docking groove 31d, an infrared transmitter 317 is further provided on the base station body 31, and at this time, an infrared receiver is provided on the robot body 11.

[0110] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, a receiving cavity 31h is further provided in the base station body 31, and a light-transmitting hole 31m is provided on the side wall of the docking groove 31d facing the groove opening thereof, and the infrared emitter 317 is arranged in the receiving cavity 31h and facing the light-transmitting hole 31m.

[0111] It can be understood that the accommodating cavity 31h provides an accommodating space for the infrared transmitter 317, which enables it to be installed more compactly on the base station body 31, and also reduces the possibility of the infrared transmitter 317 interfering with the cleaning robot 10 when the cleaning robot 10 and the base station 30 are docked. At the same time, the cavity wall of the accommodating cavity 31h also plays a certain protective role for the infrared transmitter 317, thereby reducing the possibility of the infrared transmitter 317 being damaged. In addition, it should be noted that the present application is not limited to this, and the number of infrared transmitters 317 can be two or more, so as to provide multiple alignment angles for the infrared receiver to receive and locate.

[0112] Please refer to Figure 7 In one embodiment of the present invention, in the direction from the groove side wall of the docking groove 31d facing the groove opening to the groove opening of the docking groove 31d, the groove bottom wall of the docking groove 31d is inclined downward at one end away from the groove side wall of the docking groove 31d facing the groove opening to form a guide slope.

[0113] It can be understood that the setting of the guiding slope reduces the height difference between the guiding slope and the ground, which can reduce the obstruction of the cleaning robot 10 from entering the docking slot 31d due to the height of the end of the bottom wall of the docking slot 31d where the guiding slope is formed, thereby facilitating the smoothness of the cleaning robot 10 entering the docking slot 31d. Of course, the present application is not limited thereto, and in other embodiments, the bottom wall of the docking slot 31d at various locations in the area where the guide slot 313a is not formed can also be located on the same plane, and in this case, the thickness of the bottom wall of the docking slot 31d can be set relatively thinner.

[0114] Please refer to Figure 1 In one embodiment of the present invention, the base station 30 further includes a first cleaning component 50, which is disposed in the docking slot 31d, and when the cleaning robot 10 moves into the docking slot 31d, the first cleaning component 50 can clean the cleaning brush 13 of the cleaning robot 10.

[0115] The cleaning brush 13 is used to clean the floor, and it can be a roller brush or a rag. Since garbage will be attached to the floor after the cleaning brush 13 cleans the floor, the first cleaning component 50 cleans the cleaning brush 13, so that the user does not need to clean it manually, which is conducive to further improving the use function of the base station 30 and improving its convenience. The cleaning of the cleaning brush 13 can be: combing the bristles of the cleaning brush 13 and cleaning the garbage wrapped around the cleaning brush 13.

[0116] Please refer to Figure 1 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the first cleaning component 50 includes a plurality of first cleaning columns 51, and the plurality of first cleaning columns 51 are spaced apart on the bottom wall of the docking groove 31d. When the cleaning robot 10 moves into the docking groove 31d, the first cleaning columns 51 are located below the cleaning brush 13 of the cleaning robot 10 and can abut against the cleaning brush 13 of the cleaning robot 10.

[0117] It can be understood that during the rotation of the cleaning brush 13, it can abut against the multiple first cleaning columns 51. Since the multiple first cleaning columns 51 have a blocking effect, the bristles of the cleaning brush 13 can only pass through the gaps between the multiple first cleaning columns 51, thereby achieving the combing of the bristles of the multiple cleaning brushes 13. At the same time, through the blocking effect of the first cleaning column 51, the slender strips of garbage wrapped around the cleaning brush 13 can also be blocked and limited to separate them from the cleaning brush 13. Among them, the first cleaning column 51 is a convex column-shaped structure, which can be cylindrical, square column-shaped or other columnar structures. In order to cut off the slender garbage and reduce the possibility of it being wrapped around the cleaning brush 13 and affecting the normal operation of the cleaning robot 10, a blade can be provided on the first cleaning column 51.

[0118] Of course, this application is not limited to this, please refer to Figure 1 In one embodiment of the present invention, the first cleaning component 50 also includes a plurality of first cleaning hooks 53, and the plurality of first cleaning hooks 53 are spaced apart on the bottom wall of the docking groove 31d. When the cleaning robot 10 moves into the docking groove 31d, the plurality of first cleaning hooks 53 are located below the cleaning brush 13 of the cleaning robot 10 and can abut against the cleaning brush 13 of the cleaning robot 10.

[0119] It can be understood that during the rotation of the cleaning brush 13, since the first cleaning hook 53 is a hook-shaped structure, the plurality of first cleaning hooks 53 can hook the elongated strips of garbage wrapped around the cleaning brush 13, so as to separate the elongated strips of garbage from the cleaning brush 13, thereby cleaning the cleaning brush 13. The first cleaning assembly 50 may include only a plurality of first cleaning columns 51, or only a plurality of first cleaning hooks 53, or may include both a plurality of first cleaning columns 51 and a plurality of first cleaning hooks 53. Alternatively, in another embodiment, the first cleaning assembly 51 may also be a long strip scraper, through which the garbage on the rotating cleaning brush 13 can be scraped off. Alternatively, when the cleaning brush 13 is a rag block, the first cleaning assembly 51 may be a movable cleaning block, and the rag block is cleaned by the movable cleaning block.

[0120] Please refer to Figure 1 and 3 In addition, in one embodiment, the bottom wall of the docking groove 31d may be recessed to form a groove 31e, and when the cleaning robot 10 moves into the docking groove 31d, part of the cleaning brush 13 is accommodated in the groove 31e.

[0121] It can be understood that the groove 31e can play a certain role in avoiding the cleaning brush 13, so that the cleaning brush 13 can be driven to rotate by the motor connected to it on the robot body 11 during the self-cleaning process, so as to effectively clean all parts of the circumference of the cleaning brush 13. At this time, the first cleaning component 50 can be arranged in the groove 31e. In order to further improve the cleaning effect of the cleaning brush 13, please refer to Figure 3 and Figure 4 , a base station nozzle 310 may also be provided in the groove 31e, and the base station nozzle 310 is connected to the base station clean water chamber 31b and is arranged toward the cleaning brush 13. In this way, the cleaning can be sprayed with water through the base station nozzle 310, and the dirt on the cleaning brush 13 can be effectively removed. At this time, the water after cleaning the cleaning brush 13 can also flow into the groove 31e, reducing the water flow to other positions in the docking groove 31d after cleaning the cleaning brush 13. Of course, when the suction force of the sewage extraction component 33 is large enough, the water flow flowing into the groove 31e can also be removed by the negative pressure formed by the sewage extraction component 33 in the main machine sewage collection chamber 111 (that is, sucked into the main machine sewage collection chamber 111 from the inlet of the main machine sewage collection chamber 111, and then extracted by the sewage extraction component 33), wherein the groove 31e can be a smooth groove, that is, the same shape as the cleaning brush 13, so that the two can be better adapted and distributed. Of course, the present application is not limited to this. In other embodiments, the groove 31e can also be a square groove.

[0122] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The present invention also proposes a cleaning system 100, which includes a base station 30 and a cleaning robot 10. The specific structure of the base station 30 refers to the above embodiment. Since the cleaning system 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the cleaning robot 10 includes a robot body 11, and the robot body 11 is formed with a main machine dirt collection chamber 111 and a main machine clean water chamber 112; the sewage extraction component 33 of the base station 30 can move relative to the base station body 31 and connect to the main machine dirt collection chamber 111, and the water injection component 35 of the base station 30 can move relative to the base station body 31 and connect to the main machine clean water chamber 112.

[0123] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, the robot body 11 is also provided with a sewage extraction port 11a connected to the main machine sewage collecting chamber 111 and a water injection port 11b connected to the main machine clean water chamber 112; when the sewage extraction component 33 and the water injection component 35 move relative to the base station body 31, they are respectively connected to the sewage extraction port 11a and the water injection port 11b.

[0124] It can be understood that the sewage extraction component 33 and the water injection component 35 are connected to the sewage extraction port 11a and the water injection port 11b respectively, so as to realize the sewage extraction and water injection of the cleaning robot 10, so that the sewage extraction component and the water injection component do not need to extend into the main machine sewage collection chamber 111 and the main machine clean water chamber 112, thereby reducing the requirements for the lifting stroke of the sewage extraction component and the water injection component, and can facilitate the sewage extraction component and the water injection component to be connected and connected with the cleaning robot 10 to improve the docking efficiency. Among them, the sewage extraction pipe 331 and the water injection pipe 351 are driven to descend by the driving member 37 of the base station 30 to be connected to the sewage extraction port 11a and the water injection port 11b respectively. In addition, it should be noted that the present application is not limited to this. In other embodiments, the sewage extraction pipe 331 and the water injection pipe 351 of the sewage extraction component 33 extend into the main machine sewage collection chamber 111 and the main machine clean water chamber 112 respectively for docking.

[0125] Please refer to Figure 5 , Figure 6 , Figure 8 as well as Fig. 9 In one embodiment of the present invention, the base station body 31 is provided with a pushing rod 312, and the robot body 11 is also provided with a covering plate 114, which covers the sewage extraction port 11a and the water injection port 11b and can move relative to the robot body 11; when the cleaning robot 10 moves close to the base station 30, the pushing rod 312 can abut and drive the covering plate 114, so that the covering plate 114 moves relative to the robot body 11 to open the sewage extraction port 11a and the water injection port 11b.

[0126] It can be understood that when the cleaning robot 10 moves close to the base station 30, the push rod 312 moves relative to the cleaning robot 10, and abuts the driving cover plate 114 to the sewage extraction port 11a and the water injection port 11b. In this way, there is no need for the user to manually open the cover plate 114 before docking, thereby further improving the degree of automation of the cleaning robot 10 and the base station 30 during the docking process, so as to improve the convenience of use of the cleaning system 100. Moreover, such a setting also makes it possible that when the cleaning robot 10 is cleaning the ground, the sewage extraction port 11a and the water injection port 11b are always covered by the cover plate 114, and the cover plate 114 is opened only when the cleaning robot 10 is docked with the base station 30 to realize the sewage extraction and water injection of the cleaning robot 10. Reduce the possibility of external dust or debris falling into the main machine sewage collection chamber 111 and the main machine clean water chamber 112 from the sewage extraction port 11a and the water injection port 11b, respectively, so as to ensure the normal and stable operation of the cleaning robot 10. Among them, when the base station body 31 is formed with a docking groove 31d, the push rod 312 can be arranged on the groove side wall of the docking groove 31d facing the groove opening. Of course, the present application is not limited to this. In other embodiments, it is also possible for the push rod 312 to be directly arranged on the side surface of the base station body 31. At this time, the sewage extraction component 33 and the water injection component 35 can also be directly arranged on the side surface of the base station body 31. In addition, it should be noted that when the groove side wall of the docking groove 31d is not provided with a push rod 312, it is also possible for the user to manually open the cover plate 114 before the cleaning robot 10 is docked with the base station 30.

[0127] Please refer to Fig.10 and Fig.11 In one embodiment of the present invention, the cover plate 114 is rotatably connected to the robot body 11, and can be abutted and driven by the push rod 312 to rotate relative to the robot body 11 to open the sewage extraction port 11a and the water injection port 11b.

[0128] It can be understood that the cover plate 114 is rotatably arranged on the robot body 11, so that the movement trajectory of the cover plate 114 is arc-shaped, so that the position of the cover plate 114 changes relatively little during the abutment drive process of the push rod 312, thereby reducing the possibility of the cover plate 114 interfering with other objects on the robot body 11 after the abutment drive. Of course, the present application is not limited to this. In other embodiments, the cover plate 114 can also be slidably arranged on the upper surface of the robot body 11 in the horizontal direction, and can open or cover the sewage extraction port 11a and the water injection port 11b when sliding relative to the robot body 11.

[0129] Please refer to Fig.10 and Fig.11In one embodiment of the present invention, the robot body 11 is further provided with a pressing seat 117, and the pressing seat 117 can slide relative to the robot body 11 along the extension direction of the push rod 312; the cover plate 114 is provided with a rotating shaft 115, and the rotating shaft 115 is rotatably connected to the robot body 11, and the end of the rotating shaft 115 away from the cover plate 114 is connected to the eccentric shaft 116, and the axis of the eccentric shaft 116 and the axis of the rotating shaft 115 are staggered, and the end of the eccentric shaft 116 away from the rotating shaft 115 is movably connected to the pressing seat 117; when the push rod 312 abuts against and drives the pressing seat 117 to slide relative to the robot body 11, the eccentric shaft 116 is driven by the pressing seat 117 to drive the rotating shaft 115 to rotate.

[0130] It can be understood that the push rod 312 abuts against the pressing seat 117, and then the pressing seat 117 abuts against the eccentric shaft 116, and then the push rod 312 indirectly drives the rotating shaft 115 through the eccentric shaft 116. There is no need to set a relatively complex abutment structure between the push rod 312 and the rotating shaft 115, and there is no need to insert it relatively deeply on the cleaning robot 10, which is conducive to simplifying the setting of the push rod 312. Moreover, since the pressing seat 117 slides along the extension direction of the push rod 312, it can ensure that the pressing seat 117 and the push rod 312 do not disengage during the docking process, so as to achieve a stable and effective abutment drive of the pressing seat 117, and further the eccentric shaft 116 is stably and effectively abutted and driven by the pressing seat 117. Among them, the eccentric shaft 116 and the rotating shaft 115 can be directly connected to make the connection between the two more compact. Of course, the eccentric shaft 116 and the rotating shaft 115 can be indirectly connected, that is, the two can be connected to opposite ends of the connecting rod. In addition, in one embodiment, the axis of the eccentric shaft 116 and the axis of the rotating shaft 115 can be arranged in parallel, so that the abutting force of the pressing seat 117 on the eccentric shaft 116 can be perpendicular to the axis of the rotating shaft 115, thereby facilitating the rotation of the rotating shaft 115. Of course, the present application is not limited to this, and the axis of the eccentric shaft 116 and the axis of the rotating shaft 115 can also be arranged to intersect.

[0131] Please refer to Fig.11 In one embodiment of the present invention, the first cylindrical portion 1161, the second cylindrical portion 1163 and the abutting column 1163, the first cylindrical portion 1161 is sleeved on the end of the rotating shaft 115 away from the covering plate 114; the side circumference of the second cylindrical portion 1163 is connected to the side circumference of the first cylindrical portion 1161; the abutting column 1163 is arranged on the end surface of the second cylindrical portion 1163 facing the pressing seat 117, the abutting column 1163 is movably connected to the pressing seat 117, and can be driven by the pressing seat 117.

[0132] It can be understood that the eccentric shaft 116 is fixed by the first cylindrical portion 1161 and the rotating shaft 115, which can increase the contact area between the two, thereby improving the stability of the connection between the two. Moreover, the first cylindrical portion 1161 and the rotating shaft 115 are connected in a sleeve, which also makes the connection structure between the two relatively simple, that is, the first cylindrical portion 1161 is provided with an insertion hole for the rotating shaft to be inserted, which is conducive to simplifying the structure of the eccentric shaft 116 and the rotating shaft 115. Among them, in order to reduce the possibility of slipping of the eccentric shaft 116 and the first cylindrical portion 1161, the insertion hole on the first cylindrical portion 1161 and the rotating shaft 115 embedded in the insertion hole can be provided with a stop structure. For example: the side circumference of the rotating shaft 115 embedded in the first cylindrical portion 1161 can be provided with a stop plane, and at this time, the insertion hole on the first cylindrical portion 1161 is provided with a stop mating surface that cooperates with the stop plane. Or the side circumference of the rotating shaft 115 embedded in the first cylindrical portion 1161 is provided with a stop rib, and in this case, a stop groove for inserting the stop rib is provided in the insertion hole on the first cylindrical portion 1161. The eccentric distance between the axis of the abutment column 1163 and the axis of the rotating shaft 115 is increased by the second cylindrical portion 1163, so that the abutment column 1163 of the eccentric shaft 116 drives the rotating shaft 115 of the cover plate 114 to rotate when driven by the pressing seat 117, so as to open the sewage extraction port 11a and the water injection port 11b. Among them, the first cylindrical portion 1161, the second cylindrical portion 1163 and the abutment column 1163 can be arranged in an integrated structure. Of course, it should be noted that the present application is not limited to this. In other embodiments, the eccentric shaft 116 can also include only the second cylindrical portion 1163, and in this case, the second cylindrical portion 1163 can be connected to the rotating shaft 115 through a connecting plate.

[0133] Please refer to Fig.11 In one embodiment of the present invention, the pressing seat 117 is provided with two protrusions 1171 spaced apart from each other along the sliding direction of the pressing seat 117 , and the abutting column 1163 is accommodated between the two protrusions 1171 .

[0134] It can be understood that the two protrusions 1171 enclose a movement space for the abutment column 1163 to move, so that the connection structure between the pressing seat 117 and the abutment column 1163 is simplified, which is conducive to simplifying the structure of the two and reducing the manufacturing cost. At the same time, such a setting also allows the pressing seat 117 to be directly inserted into the opening of the end of the two protrusions 1171 away from the pressing seat 117 when the two are assembled with the abutment column 1163, so that the assembly efficiency of the two can be improved. Of course, the present application is not limited to this. In other embodiments, an arc groove can also be provided on the side wall of the pressing seat 117 facing the rotating shaft 115, and the end of the abutment column 1163 away from the second cylindrical portion 1163 is inserted into the arc groove. At this time, when the pressing seat 117 is abutted and driven by the push rod 312, the abutment column 1163 can move in the arc groove.

[0135] Please refer to Fig.11 In one embodiment of the present invention, the robot body 11 is further provided with an elastic member 118 , and the elastic member 118 is connected to the robot body 11 and the pressing seat 117 .

[0136] It can be understood that when the pressing seat 117 is abutted and driven by the push rod 312, the elastic member 118 will be compressed and generate corresponding deformation elastic force. After that, when the cleaning robot 10 completes the sewage extraction, water injection and self-cleaning and moves away from the docking area of ​​the base station 30, the push rod 312 does not abut the pressing seat 117. At this time, the elastic member 118 can drive the pressing seat 117 to reset under the action of the deformation elastic force, and abut the driving abutment column 1163 so that the rotating shaft 115 of the cover plate 114 rotates and resets again, thereby realizing the automatic closing of the cover plate 114. Since the push rod 312, the pressing seat 117, the eccentric shaft 116 and the elastic member 118 are all relatively simple mechanical structures, the automatic opening and closing of the cover plate 114 is realized by a pure mechanical structure, which has the advantages of safety and reliability. Among them, the elastic member 118 can be a spring, so that the elastic member 118 has relatively good elasticity and low cost. Of course, the elastic member 118 may also be other plastic members with certain elasticity. In addition, in order to further improve the stability of the cover plate 114 when opening and closing, two push rods 312 may be provided, and at this time, two opposite sides of the cover plate 114 are provided with rotating shafts 115, each rotating shaft 115 is connected to an eccentric shaft 116, and two pressing seats 117 are provided accordingly, so that one push rod 312 abuts against and drives one pressing seat 117, and drives one eccentric shaft 116 through one pressing seat 117, thereby driving one rotating shaft 115 to rotate.

[0137] Please combine Fig. 9 ,refer to Fig.10 as well as Fig.11In one embodiment of the present invention, a mounting groove 11c is formed in a recessed manner on the upper surface of the robot body 11, and a sewage extraction port 11a and a water injection port 11b are provided on the bottom wall of the mounting groove 11c. A sliding cavity 11d is also provided in the robot body 11, and the sliding cavity 11d has an opening for inserting a push rod 312; a cover plate 114 is provided in the mounting groove 11c, and a rotating shaft 115 of the cover plate 114 is rotatably connected to the groove wall of the mounting groove 11c and extends into the sliding cavity 11d, and an eccentric shaft 116, a pressing seat 117 and an elastic member 118 are all provided in the sliding cavity 11d.

[0138] It can be understood that the mounting groove 11c provides a space for accommodating the cover plate 114, which can make the cover plate 114 more compactly installed on the robot body 11. At the same time, it is also conducive to making the upper surface of the cover plate 114 and the robot body 11 smoother, reducing the possibility of the cover plate 114 being damaged by colliding with obstacles during the movement of the cleaning robot 10. The sliding cavity 11d provides an accommodating space for the eccentric shaft 116, the pressing seat 117 and the elastic member 118, which can make their installation more compact and reduce the space occupied. At the same time, the cavity wall of the sliding cavity 11d also plays a certain protective role for the eccentric shaft 116, the pressing seat 117 and the elastic member 118, reducing the possibility of them being damaged by foreign objects. Among them, when the eccentric shaft 116, the pressing seat 117 and the elastic member 118 are each provided with two, the sliding cavity 11d is correspondingly provided with two, and is respectively located on the opposite sides of the cover plate 114. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the cover plate 114 , the eccentric shaft 116 , the pressing seat 117 and the elastic member 118 may be directly disposed on the upper surface of the robot body 11 .

[0139] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, the cleaning robot 10 also includes a cleaning brush 13, which is disposed on the robot body 11; the cleaning robot 10 also includes a second cleaning component 70, which is disposed on the robot body 11, and the second cleaning component 70 can clean the cleaning brush 13 of the cleaning robot 10.

[0140] The cleaning brush 13 is used to clean the floor, and it can be a roller brush or a rag. Since garbage will be attached to the floor after the cleaning brush 13 cleans the floor, the cleaning brush 13 can be cleaned by the second cleaning component, so that the user does not need to clean it manually, which is conducive to further improving the use function of the base station 30 and improving its convenience. The cleaning of the cleaning brush 13 can be: combing the bristles of the cleaning brush 13. And cleaning the garbage (such as hair or other thin strips of garbage) wrapped around the cleaning brush 13.

[0141] Please refer to Figure 3 and Figure 4 In one embodiment of the present invention, the second cleaning assembly 70 includes a plurality of second cleaning columns 71 , and the plurality of second cleaning columns 71 are spaced apart from the robot body and can abut against the cleaning brush 13 of the cleaning robot 10 .

[0142] It can be understood that during the rotation of the cleaning brush 13, it can abut against the multiple second cleaning columns 71. Since the multiple second cleaning columns 71 have a blocking effect, the bristles of the cleaning brush 13 can only pass through the gaps between the multiple second cleaning columns 71, thereby achieving the combing of the bristles of the multiple cleaning brushes 13. At the same time, through the blocking effect of the second cleaning column 71, the slender strips of garbage entangled with the cleaning brush 13 can also be blocked and limited to separate them from the cleaning brush 13. Among them, the second cleaning column 71 is a convex columnar structure, which can be cylindrical, square columnar or other columnar structures. In order to cut off the slender garbage and reduce the possibility of it being entangled in the cleaning brush 13 and affecting the normal operation of the cleaning robot 10, a blade can be provided on the second cleaning column 71.

[0143] Of course, the present application is not limited thereto. In another embodiment of the present invention, please refer to Figure 3 and Figure 4 The second cleaning assembly 70 further includes a plurality of second cleaning hooks 73 , which are spaced apart from the robot body and can abut against the cleaning brush 13 .

[0144] It can be understood that during the rotation of the cleaning brush 13, since the second cleaning hook 73 is a hook-shaped structure, the elongated strip of garbage wrapped around the cleaning brush 13 can be hooked by multiple second cleaning hooks 73 to separate it from the cleaning brush 13, thereby cleaning the cleaning brush 13. Among them, the second cleaning component 70 can be only composed of multiple second cleaning columns 71, or can be only composed of multiple second cleaning hooks 73, or can be composed of multiple second cleaning columns 71 and multiple second cleaning hooks 73. Alternatively, in another embodiment, the second cleaning component 70 can also be a long strip scraper, through which the garbage on the rotating cleaning brush 13 can be scraped off. Alternatively, when the cleaning brush 13 is a rag block, the second cleaning component 70 can be a movable cleaning block, and the rag block is cleaned by the movable cleaning block. In addition, in order to further improve the cleaning effect of the cleaning brush 13, the host nozzle 11g provided on the robot body 11 and connected to the host water chamber 112 can be facing the cleaning brush 13. In this way, by opening the main machine nozzle 11g, water can be sprayed on the cleaning brush 13, so that the cleaning brush 13 can be sprayed with water to clean it during the docking process between the cleaning robot 10 and the base station 30, and when the cleaning robot 10 cleans the ground, the cleaning brush 13 is wetted to scrub the ground. Of course, the present application is not limited to this, and in other embodiments, the main machine nozzle 11g provided on the robot body 11 and connected to the main machine water chamber 112 can also be directly facing the ground.

[0145] Furthermore, it should be noted that the cleaning system 100 in the present application may be a system in which only the first cleaning component 50 is provided on the base station 30 for cleaning the cleaning brush 13; or a system in which only the second cleaning component 70 is provided on the cleaning robot 10 for cleaning the cleaning brush 13; or, alternatively, a first cleaning component 50 is provided on the base station 30 for cleaning the cleaning brush 13, and a second cleaning component 70 is provided on the cleaning robot 10 for cleaning the cleaning brush 13.

[0146] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
