The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0059] As people's living standards continue to improve, cleaning systems equipped with cleaning robots and cleaning base stations have gradually become common smart home appliances in ordinary households.

[0060] The cleaning base station is usually equipped with a dust collection box. During use, a dust bag can be set in the dust collection bin of the dust collection box to collect the dust generated by the cleaning robot during the cleaning process.

[0061] In related designs, the dust box usually has a box cover, so that the user can take out or place the dust bag by opening the box cover during use. However, when the box cover is provided, the structure of the dust box will be complicated and the production cost of the cleaning base station will be additionally increased.

[0062] To solve the above problems, please refer to Figure 1 The present application proposes a cleaning system, which includes a cleaning device (not shown) and a cleaning base station 100, and the cleaning device and the cleaning base station 100 are cooperatively connected.

[0063] The cleaning device can be a cleaning robot, which has a side sweeper, a first suction component, a water tank and a mop, etc. The side sweeper is used to gather garbage to the suction port of the first suction component, the mop is used to clean the floor, and the water tank continuously provides cleaning liquid to the mop during the cleaning operation of the cleaning robot.

[0064] Please refer to Figures 2 to 4 The cleaning base station 100 includes a housing 10, a dust collecting fan, a second suction component, a liquid storage tank 30, a water pump component, a drying component, a charging component, a circuit board, and a controller electrically connected to the circuit board. The housing 10 is provided with a water tank groove 13a with an opening 13b facing upward at its upper portion. It can be understood that the opening 13b of the water tank groove 13a can be facing directly upward or can be arranged obliquely upward. The liquid storage tank 30 is inserted into the water tank groove 13a. By providing the water tank groove 13a at the upper portion of the housing 10, and the opening 13b of the water tank groove 13a facing upward, it is convenient for the user to apply force to the liquid storage tank 30 to pull it out of the housing 10.

[0065] The housing 10 is provided with a dust collecting bin 15a with an opening 15b facing upward in the middle thereof. It is understandable that the opening 15b of the dust collecting bin 15a may be facing upward or obliquely upward. The water tank tank 13a is located above the dust collecting bin 15a, and the opening 15b of the dust collecting bin 15a is connected to the water tank tank 13a. During use, a dust bag may be provided, and the dust bag may be sleeved in the dust collecting bin 15a, so that the dust collected by the cleaning robot can enter the dust collecting bin 15a and be collected by the dust bag under the drive of the dust collecting fan. When the dust bag is full of dust, the user can remove the liquid storage tank 30, remove the entire dust bag from the opening 15b of the dust collecting bin 15a, and then replace it with a new dust bag, which is easy to operate.

[0066] The liquid storage tank 30 may include two independently arranged clean water tanks 35 and sewage tanks 37, wherein the water tank slots 13a may also be provided with two, two for installing the clean water tank 35 and the sewage tank 37 respectively. Of course, the water tank slot 13a may also be provided with one, and the clean water tank 35 and the sewage tank 37 are both provided in the one water tank slot 13a. Alternatively, the liquid storage tank 30 may also be provided with the clean water tank 35 and the sewage tank 37 being made into one body, and the water tank slot 13a is provided with one, and the specific setting mode is not limited by the present application.

[0067] The outer wall surface of the liquid storage tank 30 is formed with a first guide surface 39, and the side wall of the water tank groove 13a is formed with a second guide surface 135 (see Figure 4), wherein the first guide surface 39 and the second guide surface 135 can both be in the form of an inclined surface, and the two can achieve sliding cooperation. During the placement of the liquid storage tank 30, under the guidance cooperation of the first guide surface 39 and the second guide surface 135, the liquid storage tank 30 can be guided to a predetermined position for assembly, which is convenient for users to install the liquid storage tank 30 during daily use.

[0068] The housing 10 is also formed with a housing portion 17a having a lateral opening 13b below the dust collecting bin 15a, and the dust collecting fan, the second suction assembly, the water pump assembly, the drying assembly, the charging assembly and the circuit board are all installed in the housing 10, and the suction port in the second suction assembly, the charging port in the charging assembly, and the water injection port in the water pump assembly can be set on the groove wall of the housing portion 17a. Specifically, the housing 10 in the cleaning base station 100 may include a middle frame 13, a dust collecting shell 15, an outer shell 11 and a base 17. The outer shell 11 defines the outline of the entire cleaning base station 100. The middle frame 13 is covered on the upper part of the outer shell 11 and is formed with a water tank groove 13a. Please refer to Figure 4 The dust collecting shell 15 is connected to the middle part of the outer shell 11 and is also connected to the bottom of the middle frame 13. The base 17 is connected to the bottom of the outer shell 11 and cooperates with the outer shell 11 to define a accommodating portion 17a, wherein the second suction component, the charging component and the water pump component can be installed in the cavity surrounded by the middle frame 13 and the outer shell 11.

[0069] The dust collecting bin 15a is formed in the dust collecting shell 15. Since the bin opening 15b of the dust collecting bin 15a of the present application is opened on the bottom wall 1311 of the water tank tank 13a, the entire dust collecting bin 15a can fully occupy the space below the water tank tank 13a and can extend in the horizontal direction of the cleaning base station 100. In this way, the volume of the dust collecting bin 15a can be increased while the height dimension of the cleaning base station 100 remains unchanged. With this arrangement, a larger dust bag can also be placed in the dust collecting bin 15a to collect more dust, thereby reducing the number of times the dust bag is replaced and improving the user experience.

[0070] In order to make full use of the internal space of the cleaning base station 100 and make its structure compact, the circuit board of the cleaning base station 100 can be installed on the shell wall of the dust collecting shell 15, for example, it can be installed on the rear shell wall or the front shell wall of the dust collecting shell 15, so that the dust collecting shell 15 can also serve as a load-bearing mounting component for the circuit board, so that the casing 10 does not need to be provided with specific mounting components to realize the installation of the circuit board, so that the overall structure of the casing 10 is simpler and the utilization rate is higher.

[0071] During use, the cleaning robot at least partially enters the accommodating portion 17a and docks with the suction port, charging port and water outlet in the accommodating portion 17a, thereby realizing automatic charging through the charging component, sucking the cleaning liquid in the liquid storage tank 30 through the water pump component and adding it to the cleaning robot, and transferring the garbage of the cleaning robot through the second suction component.

[0072] During the dust collection process, the dust collecting bin 15 a needs to be sealed to prevent the dust in the dust collecting bin 15 a from flying out of the bin opening 15 b , so as to prevent the dust from being poorly collected and affecting other components in the housing 10 .

[0073] In this regard, the present application further blocks the port 15b at the bottom of the liquid storage tank 30, so as to seal the dust collection bin 15a and prevent dust from flying out from the port 15b. It is understandable that the specific forms of blocking the port 15b at the bottom of the liquid storage tank 30 to seal the dust collection bin 15a can be as follows:

[0074] First, the bottom of the liquid storage tank 30 may be sealed at the port 15b to seal the dust collection bin 15a. That is, in this form, the bottom of the liquid storage tank 30 seals the port 15b, and the bottom of the liquid storage tank 30 does not need to be inserted into the dust collection bin 15a.

[0075] Second, the bottom of the liquid storage tank 30 may be inserted into the dust collecting bin 15a through the bin opening 15b to seal the dust collecting bin 15a. That is, in this form, the bottom of the liquid storage tank 30 is inserted into the dust collecting bin 15a, and its outer wall surface abuts against the inner wall of the dust collecting bin 15a to achieve sealing of the dust collecting bin 15a.

[0076] In this way, the dust collecting bin 15a is sealed by blocking the port 15b at the bottom of the liquid storage tank 30, so that the dust collecting bin 15a can better collect dust and prevent dust from flying out from the port 15b. In addition, the cleaning base station 100 does not need to be specially equipped with additional structural components such as a bin cover to block the port 15b of the dust collecting bin 15a. In the absence of a bin cover, the number of structures of the cleaning base station 100 can be reduced, making the overall structure of the cleaning base station 100 simpler, reducing the overall production cost of the cleaning base station 100, and compared with the solution in which the cleaning base station 100 has a bin cover and the bin cover is externally placed and exposed to the shell 11 of the housing 10, the dust collecting bin 15a of the present application will be hidden inside the housing 10, and the appearance consistency of the housing 10 of the cleaning base station 100 is higher, making the appearance of the housing 10 more beautiful and simple.

[0077] In addition, please refer to Figures 7 and 8The housing 10 is provided with a joint 1371 on the wall of the water tank groove 13a, and the liquid storage tank 30 is provided with a connection hole 3111 connected to the joint 1371. The detection device is used to detect the installation status of the liquid storage tank 30 to obtain the status information of the liquid storage tank, and the controller controls the start of the dust collecting fan when the status information indicates that the liquid storage tank 30 is installed in place. When the dust collecting fan is started, a negative pressure environment can be formed in the dust collecting bin 15a, and the bottom of the liquid storage tank 30 can further tightly seal the bin opening 15b, and the joint 1371 is tightly plugged into the connection hole 3111, so that the dust collecting fan can be automatically started, and there is no need to manually start the dust extraction function of the cleaning base station 100 after the liquid storage tank 30 is placed. It is more intelligent and improves the user experience. Please refer to Figure 1 to Figure 2 In actual use, when the cleaning robot returns to the accommodating portion 17a in the cleaning base station 100, the user can install the liquid storage tank 30 in the water tank slot 13a. At this time, the detection device can detect whether the liquid storage tank 30 is installed in place. If it is installed in place, the installation information will be output to the controller. At this time, the controller will provide a trigger signal to the dust collecting fan, and the dust collecting fan will start to start exhaust, so that a negative pressure environment is formed in the dust collecting bin 15a, and the sewage tank 37 of the liquid storage tank 30 will produce a downward movement under the force of atmospheric pressure, so that the sewage tank of the liquid storage tank 30 The bottom of 37 can better seal the port 15b, and the connector 1371 will be tightly inserted into the connection hole 3111, and the cleaning base station 100 can also include a sealing sleeve, which can be in the form of a silicone sleeve, and the sealing sleeve is sleeved on the connector 1371. Under the action of downward pressure, the interference between the side wall of the connection hole 3111 and the sealing sleeve is increased, so that the side wall of the connection hole 3111 will fit more closely with the outer wall of the sealing sleeve, avoiding leakage of sewage, etc., so as to improve the sewage extraction efficiency of the cleaning base station 100, so that the sewage extraction effect of the cleaning base station 100 will be better. Of course, the user can also install the liquid storage tank 30 in the water tank slot 13a and manually start the dust extraction function of the cleaning base station 100, which is not limited to this.

[0078] In one structural form, the detection device may be a Hall sensor, and accordingly, a magnetic member may be provided on the tank body 31 of the liquid storage tank 30, so that the installation state of the liquid storage tank 30 can be detected through the cooperation between the Hall sensor and the magnetic member. Specifically, the magnetic member may be installed on the inner wall surface of the tank body 31, so as not to affect the appearance of the tank body 31. Of course, the detection device may also be a photoelectric sensor or other form of sensor, which is not limited thereto.

[0079] For further information, please refer to Figures 7 and 8The housing 10 is also provided with a lap step 137 on the side wall of the water tank groove 13a, and the joint 1371 is provided on the lap step 137. The side wall of the liquid storage tank 30 is recessed to form a lap groove 311 for cooperating with the lap step, and the groove wall of the lap groove 311 is provided with the connection hole 3111. In this way, when placing the liquid storage tank 30, the user can align the lap step 311 with the lap groove 133 to achieve the placement of the liquid storage tank 30 after the lap step 311 overlaps and aligns with the water tank groove 13a, which is convenient for the user to place the liquid storage tank 30.

[0080] In one structural form, at least a portion of the side wall of the connecting hole 3111 is formed with a guide bevel, and the guide bevel is used to be inclinedly matched with the outer side wall of the sealing sleeve.

[0081] In one embodiment, please refer to Figures 4 to 7 The liquid storage tank 30 includes a tank body 31 and an inserting portion 33 connected to the bottom of the tank body 31. When the liquid storage tank 30 is a clean water tank 35, the tank body 31 is used to store cleaning liquid, and when the liquid storage tank 30 is a sewage tank 37, the tank body 31 is used to store sewage.

[0082] The inserting portion 33 is sealed and inserted into the port 15b of the dust collecting bin 15a to seal the dust collecting bin 15a. The inserting portion 33 can be a part of the box structure of the liquid storage tank 30, or it can be a bottom frame located at the bottom of the box body 31. The box body 31 can be placed on a plane through the bottom frame to improve the placement stability. When the inserting portion 33 is a bottom frame, the bottom frame can include a frame and reinforcing ribs arranged in the frame, so as to improve the strength of the frame through the setting of the reinforcing ribs. In this way, it is also possible to make the frame less likely to deform when in contact with the inner side wall of the dust collecting bin 15a, thereby improving the sealing effect of the dust collecting bin 15a. Under such a setting, the dust collecting bin 15a can be sealed by inserting the inserting portion 33, which is convenient for the user to seal. As one of the components of the liquid storage tank 30 itself, the inserting portion 33 can utilize the structure of the liquid storage tank 30 itself to achieve the sealing of the dust collecting bin 15a, without the need to design an additional sealing structure, so that the structure of the liquid storage tank 30 is simpler.

[0083] The liquid storage tank 30 may also be a form in which the tank body 31 and the inserting part 33 are made into one piece, which can facilitate the workshop to manufacture the liquid storage tank 30 and improve the connection strength between the two. Of course, the tank body 31 and the inserting part 33 may also be made into separate pieces. For example, according to the actual size of the port 15b to be inserted, the inserting part 33 of the corresponding size may be selected to be assembled with the tank body 31 to improve the adaptability. The specific setting method is not limited in this application.

[0084] In order to improve the sealing performance between the insertion portion 33 of the liquid storage tank 30 and the dust collecting bin 15a, a sealing gap 19 is formed between the insertion portion 33 and the inner side wall of the dust collecting bin 15a, and the cleaning base station 100 further includes a first sealing member 50 disposed in the sealing gap 19, and the first sealing member 50 is used to seal the sealing gap 19. During the production process, there will always be deviations in the dimensional accuracy of the insertion portion 33 of the liquid storage tank 30, and there will also be deviations in the dust collecting shell 15, so that when the insertion portion 33 of the liquid storage tank 30 is inserted into the dust collecting bin 15a, there will always be a certain gap (that is, the above-mentioned sealing gap 19) between the insertion portion 33 and the inner side wall of the dust collecting bin 15a, so the present application is provided with a first sealing member 50, and the sealing of the sealing gap 19 is achieved by the first sealing member 50, so as to further improve the sealing effect of the liquid storage tank 30 on the dust collecting bin 15a.

[0085] During the process of inserting the insertion part 33 into the opening 15b of the dust collecting bin 15a, in order to facilitate user operation, the inner wall of the dust collecting bin 15a is formed with a fixing groove 15c connected to the sealing gap 19, and the first sealing member 50 is fixedly arranged in the fixing groove 15c. Thus, the first sealing member 50 can be fixed in the fixing groove 15c first, and then the insertion part 33 is inserted into the opening 15b, and the insertion part 33 is abutted against the first sealing member 50 to realize the sealing installation process, which is easy to operate and improves the user experience. In addition, the first sealing member 50 can be fixed in the fixing groove 15c, so that the first sealing member 50 is not easily disconnected from the housing 10, and the first sealing member 50 can be firmly installed under long-term use.

[0086] In one structural form, please refer to Figure 10 to Figure 11 The first sealing member 50 includes a sealing inner ring 51 and a sealing outer ring 53 surrounding the outer side of the sealing inner ring 51. The sealing inner ring 51 and the sealing outer ring 53 realize the common sealing of the sealing gap 19.

[0087] The fixing groove 15c includes a first sub-fixing groove 15d and a second sub-fixing groove 15e, the sealing inner ring 51 is fixedly arranged in the first sub-fixing groove 15d, and the sealing outer ring 53 is fixedly arranged in the second sub-fixing groove 15e. In this arrangement, the sealing inner ring 51 and the sealing outer ring 53 are respectively fixed in the first sub-fixing groove 15d and the second sub-fixing groove 15e, respectively, so as to further improve the fixing effect of the first sealing member 50 and the inner side wall of the dust collecting bin 15a, so that the first sealing member 50 is more firmly fixed in the dust collecting bin 15a, and is less likely to fall off or shift in position.

[0088] In order to facilitate the installation of the first sealing member 50 in the fixing groove 15c, the first sealing member 50 includes a sealing body 55 and a positioning portion 57 connected to each other. The sealing body 55 is fixedly arranged in the fixing groove 15c and is used to seal the sealing gap 19. The sealing inner ring 51 and the sealing outer ring 53 together form the above-mentioned sealing body 55, and the positioning portion 57 can be specifically connected to the sealing inner ring 51 of the sealing body 55, or connected to the sealing outer ring 53 of the sealing body 55, and the present application does not limit this.

[0089] The bottom wall of the fixing groove 15c is recessed to form a positioning groove 15f, and the groove walls at both ends of the positioning groove 15f along the extension direction cooperate with the positioning portion 57 stopper to limit the installation position of the sealing body 55. During the installation process, the positioning portion 57 and the positioning groove 15f can be aligned first, and then the two can be installed. At this time, the position of the sealing body 55 and the fixing groove 15c will also be relatively fixed, and then the sealing body 55 can be pressed to fix the sealing body 55 in the fixing groove 15c. In this way, while facilitating the installation of the first sealing member 50, the position accuracy of the first sealing member 50 when installed in the fixing groove 15c is improved.

[0090] On the basis that the sealing body 55 of the first sealing member 50 is arranged in the fixing groove 15c, in order to further improve the stability of the first sealing member 50 when it is fixed in the fixing groove 15c, the sealing body 55 of the first sealing member 50 in the present application is provided with abutting ribs 58 in the partial structure arranged in the fixing groove 15c, that is, the sealing inner ring 51 and / or the sealing outer ring 53 of the sealing body 55 of the first sealing member 50 can be formed with abutting ribs 58. The abutting ribs 58 abut against the inner side wall of the fixing groove 15c. In this way, the friction between the abutting ribs 58 and the inner side wall of the fixing groove 15c improves the firmness of the first sealing member 50 fixed in the fixing groove 15c, and it is not easy to fall off.

[0091] In the scheme shown in the figure, the number of abutment ribs 58 can be at least 2, for example, 2, 3 or 4, etc., wherein at least 2 abutment ribs 58 are arranged at intervals along the height direction of the first seal 50 to further increase the friction between the abutment ribs 58 and the inner side wall of the fixing groove 15c.

[0092] In one structural form, the surface of the sealing outer ring 53 of the first sealing member 50 facing the liquid storage tank 30 is formed with an annular first sealing rib 59, and the first sealing rib 59 is used to abut or disengage from the outer wall of the liquid storage tank 30 when the insertion portion 33 is inserted into or separated from the dust collection bin 15a. Since the first sealing rib 59 itself has a certain elastic deformation, when the insertion portion 33 is inserted into or separated from the dust collection bin 15a, under the contact between the insertion portion 33 and the first sealing rib 59, the first sealing rib 59 will produce a certain elastic deformation to abut or disengage from the outer wall of the box body 31 of the liquid storage tank 30, that is, in the sealed state, the first sealing rib 59 will abut the outer wall of the box body 31 of the liquid storage tank 30, and in the unsealed state, driven by the outer wall of the box body 31 of the liquid storage tank 30, the first sealing rib 59 will be deformed to disengage from the outer wall of the box body 31 of the liquid storage tank 30. In this way, even when the first sealing member 50 is provided, it is convenient for the user to take and place the liquid storage tank 30, the operation is more convenient, and the user experience is improved.

[0093] Furthermore, the first sealing rib 59 has a guide surface inclined downward, and the guide surface is used to guide and cooperate with the outer wall of the liquid storage tank 30. In this way, when the user places the liquid storage tank 30 in the water tank groove 13a, the guide surface will contact the outer wall of the box body 31 to play a guiding effect, so that the box body 31 has a tendency to move downward, which is more convenient for the user to place the liquid storage tank 30. At the same time, under the negative pressure formed in the dust collection bin 15a, when the liquid storage tank 30 is in the water tank groove 13a, under the guidance of the first sealing rib 59, the liquid storage tank 30 can move downward better so that the insertion portion 33 can be inserted into the dust collection bin 15a more smoothly.

[0094] In the scheme shown in the figure, the number of first sealing ribs 59 can be at least 2, for example, 2, 3 or 4, etc., wherein at least 2 first sealing ribs 59 are arranged at intervals along the height direction of the first sealing member 50 to further improve the sealing effect of the first sealing ribs 59.

[0095] In one embodiment, the middle frame 13 further includes a frame body 131 and an inserting portion 133 connected to the bottom of the frame body 131, and the upper surface of the dust collecting shell 15 is further formed with an inserting groove 15g for the inserting portion 133 to be inserted. A second sealing member 60 is further provided between the inserting portion 133 and the bottom wall of the inserting groove 15g. In this way, on the basis of realizing the widening of the volume of the dust collecting bin 15a, the second sealing member 60 can be used to seal the gap between the inserting portion 133 and the bottom wall of the inserting groove 15g, thereby further improving the overall sealing effect of the dust collecting bin 15a.

[0096] The plug-in portion 133 can be constructed as a frame-type structure, and the shape of the plug-in slot 15g is adapted to the shape of the plug-in portion 133, so that the contact area between the plug-in portion 133 and the bottom wall of the plug-in slot 15g is increased through the frame-type structure, and the connection stability when the plug-in portion 133 is plugged into the plug-in slot 15g is increased. At the same time, the shape of the frame-type structure is relatively regular, which is convenient for the workshop to produce the plug-in portion 133.

[0097] The above content introduces the advantages of the cleaning base station 100 of the present application having a good sealing effect on the dust collection bin 15a from the aspect of the sealing setting form of the liquid storage tank 30 and the dust collection bin 15a. On this basis, in order to avoid the phenomenon of mold and bacteria breeding caused by moisture in the water tank tank 13a, the present application also makes the following improvements:

[0098] After long-term use, when more sewage is collected in the liquid storage tank 30 or the remaining cleaning liquid in the liquid storage tank 30 is not much, the user will pull out the liquid storage tank 30 to dump the sewage, clean the liquid storage tank 30, or add cleaning liquid. In this process, it is inevitable that liquid will adhere to the outside of the liquid storage tank 30. When the user re-inserts the liquid storage tank 30 into the water tank slot 13a, the liquid will accumulate in the water tank slot 13a. If it is not cleaned in time, it is easy to cause mold and bacteria to grow due to moisture.

[0099] In this regard, the present application further provides a drainage hole 13c connected to the water tank groove 13a in the casing 10 (that is, specifically, a drainage hole 13c is provided on the middle frame 13), and a drainage channel connected to the drainage hole 13c is provided, and the liquid accumulated in the water tank groove 13a is discharged to the drying component through the drainage channel.

[0100] Therefore, during use, after the user installs the liquid storage tank 30 back into the water tank groove 13a, even if there is liquid attached to the outside of the liquid storage tank 30 and the liquid accumulates in the water tank groove 13a, the liquid can be quickly discharged to the drying component through the drainage hole 13c and the drainage channel, and the liquid is quickly evaporated and removed by the drying component, thereby keeping the water tank groove 13a in a dry state. In this way, it is not easy for the water tank groove 13a to be moldy or breed bacteria due to moisture.

[0101] In one embodiment, see Figure 8 The cleaning base station 100 also includes a wiper 90, which is fixed to the side wall of the water tank groove 13a. The wiper 90 is used to contact the outer wall of the liquid storage tank 30 during the process of inserting the liquid storage tank 30 into the water tank groove 13a to scrape off the liquid on the outer wall of the liquid storage tank 30.

[0102] In the process of inserting the liquid storage tank 30 into the water tank groove 13a of the present application, the wiper member 90 and the outer wall of the liquid storage tank 30 are interference fit, so that the liquid on the outer wall of the liquid storage tank 30 can be quickly scraped off and discharged to the drying component through the drainage hole 13c and the drainage channel. In this way, the combination of the wiper member 90 and the drying component can improve the efficiency of removing the liquid attached to the outer wall of the liquid storage tank 30.

[0103] The liquid storage tank 30 may be in the shape of a rectangular parallelepiped, a cube or other polygonal prism with multiple outer side walls. Of course, it may also be in the shape of a cylindrical or elliptical cylinder with an arc-shaped outer wall. The present application does not limit the shape of the liquid storage tank 30. In order to improve the efficiency of scraping liquid on the outer side wall of the liquid storage tank 30, the number of wipers 90 is multiple, and multiple wipers 90 are arranged around the liquid storage tank 30. For example, when the liquid storage tank 30 is in the form of a rectangular parallelepiped, the present application may be provided with at least one wiper 90 corresponding to each outer side wall of the liquid storage tank 30, so that the number of wipers 90 is at least 4. Of course, the present application may also be provided with 2, 3 wipers 90, etc. corresponding to each outer side wall of the liquid storage tank 30. When the number of wipers 90 corresponding to each outer side wall of the liquid storage tank 30 is greater than 2, the multiple wipers 90 may be arranged at intervals in the depth direction of the water tank groove 13a, or at intervals in the circumferential direction of the water tank groove 13a. When the profile is roughly in the form of a cylinder or an elliptical cylinder, the wiper member 90 can be multiple and arranged at intervals in the circumferential direction of the water tank groove 13a and also arranged around the liquid storage tank 30. Through the above arrangement, the liquid on multiple outer side walls of the liquid storage tank 30 can be scraped off at the same time, and the efficiency is further improved.

[0104] The wiper member 90 of the present application can be in the shape of a long strip, and can be made of materials such as plastic, silicone, and foam. The fixed connection between the wiper member 90 and the side wall of the water tank tank 13a includes, but is not limited to, bonding, snap-on, and the like. The wiper member 90 is closer to the opening 13b of the water tank tank 13a than the bottom wall of the water tank tank 13a. For example, the wiper member 90 can be set at two-thirds of the height of the water tank tank 13a or above two-thirds of the height of the water tank tank 13a. In this way, the wiper member 90 can meet the use requirements, and during the process of inserting the liquid storage tank 30 into the water tank tank 13a, the contact area with the side wall of the liquid storage tank 30 is larger, so as to more thoroughly scrape off the liquid on the outer wall of the liquid storage tank 30.

[0105] The wiper member 90 includes a wiper surface 91 located at the upper part thereof. When the liquid storage tank 30 is inserted into the water tank groove 13a, the edge of the wiper surface 91 away from the side wall of the water tank groove 13a contacts the outer side wall of the liquid storage tank 30. There is an angle between the wiper surface 91 and the horizontal plane to guide the scraped liquid to the drainage hole 13c. That is, the wiper surface 91 has two ends in the length direction of the wiper member 90, one end is at a lower height than the other end, and the lower end is close to the drainage hole 13c to guide the liquid to the drainage hole 13c. By such an arrangement, liquid is not easy to remain in the water tank groove 13a, and the removal is more thorough.

[0106] Furthermore, since the receiving portion 17a in the cleaning base station 100 has a lateral opening 13b on the front side of the housing 10, the position of the opening 13b facilitates the arrangement of the drainage hole 13c and the drainage channel without interfering with other structures. The present application can arrange the drainage hole 13c at a position where the water tank groove 13a is close to the rear side of the cleaning base station 100.

[0107] For example, Fig. 9 In the exemplary embodiment shown in FIG. 1 , the drainage hole 13c is arranged on the bottom wall of the water tank groove 13a and close to the rear side of the cleaning base station 100. Thus, for the wiper 90 extending in the front-to-back direction, the end of the wiper surface 91 close to the front side of the cleaning base station 100 may be higher than the end close to the rear side of the cleaning base station 100, so that the scraped liquid flows toward the drainage hole 13c, thereby accelerating the efficiency of liquid discharge.

[0108] When a wiper member 90 is provided, the drainage hole 13c of the present application can be disposed on the bottom wall of the water tank tank 13a, or on the side wall of the water tank tank 13a, and the drainage hole 13c can be the end with a lower height connected to the wiper surface 91 of the water hanging member.

[0109] It is understandable that when the drainage hole 13c is arranged on the bottom wall of the water tank groove 13a, and the liquid drainage efficiency meets the basic use requirements, the present application may also not arrange the wiper member 90.

[0110] On the basis that the drainage hole 13c is arranged on the bottom wall of the water tank tank 13a, in order to drain the liquid more thoroughly, the present application can form the bottom wall of the water tank tank 13a into an inclined surface, and the drainage hole 13c is arranged at the lowest point of the inclined surface; or, the bottom wall of the water tank tank 13a is formed with a recessed area, and the drainage hole 13c is located at the lowest point of the recessed area. As shown in the figure, the bottom wall of the water tank tank 13a extends from top to bottom in the direction from the front side to the rear side of the cleaning base station 100. Through the above arrangement, the gravity factor can be fully utilized to guide the liquid in the water tank tank 13a to the drainage hole 13c as thoroughly as possible.

[0111] Furthermore, the number of drainage holes 13c in the present application is at least two, and the number of drainage channels corresponds to the number of drainage holes 13c. For example, as exemplarily shown in the figure, the two drainage holes 13c are both located at the bottom wall of the water tank groove 13a close to the rear side of the cleaning base station 100. And they are spaced in the left and right directions of the cleaning base station 100. With this arrangement, the liquid discharge efficiency can be further improved. It can be understood that the number of corresponding drainage holes 13c can also be other, such as 3, 4, etc., which is not limited by the present application. Moreover, the number of drainage channels may not correspond to the number of drainage holes 13c. For example, two drainage holes 13c may be connected to the drying component through a drainage channel, which is not limited by the present application.

[0112] The drainage channel of the present application may be formed by the structure of the housing 10 itself, that is, the drainage channel may be formed in the wall of the outer shell 11. This form makes the entire cleaning base station 100 simple and compact in structure.

[0113] From the perspective of facilitating production and manufacturing, the formation of the drainage channel of the present application is aided by an additional drainage pipe 70. The drainage channel includes two parts: a flow guide channel 17c and a drainage pipe 70. The housing 10 is also formed with a drying tank 17b connected to the accommodating portion 17a, and a drying component is installed in the drying tank 17b, wherein the drying component can be in the form of a fan and a heating wire, and the fan blows the heat generated by the heating wire from the drying tank 17b to the accommodating portion 17a. Of course, the specific form of the drying component can also be other, and the present application does not limit this.

[0114] The flow guide 17c is formed by the inner wall of the receiving portion 17a being concave, specifically, by the upper surface of the receiving portion 17a being concave surrounded by the base 17, and the flow guide 17c is connected to the drying tank 17b. The drainage pipe 70 is fixed in the cavity surrounded by the housing 11 and the middle frame 13, and the drainage pipe 70 can be made of silica gel, plastic, etc. One end of the drainage pipe 70 is connected to the drainage hole 13c, and the other end is connected to the flow guide 17c.

[0115] By providing the drainage pipe 70 externally, when the drainage channel is arranged in the cleaning base station 100, there is no need to make major modifications to the original housing 10 of the cleaning base station 100, thereby reducing the design cost. In addition, the drying component of the present application is arranged in the drying tank 17b connected to the accommodating portion 17a, so that the drying component can realize the existing function of heating and drying the mop of the cleaning robot, and also realizes the function of heating and drying the liquid in the water tank tank 13a, thereby reducing the production cost.

[0116] It is understandable that in other structural forms, the drying assembly can also be used alone to dry the liquid in the water tank 13a, that is, two sets of drying assemblies can be provided in the cleaning base station 100. Alternatively, the drainage channel of the present application can also be composed of a drainage pipe 70 alone, and the drainage pipe is directly connected to the drying tank 17b.

[0117] In one embodiment, the detection device can also provide a trigger signal for starting the drying component. When in use, after the liquid storage tank 30 is placed in the water tank slot 13a, the detection device is triggered and transmits the trigger signal to the controller of the cleaning base station 100, so that the controller further controls the drying component to start, thereby timely draining the liquid in the water tank slot 13a. Through the setting of the detection device, the liquid discharge process is relatively timely, and the manual operation process is also omitted, which can improve the convenience of use.

[0118] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0119] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
