Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a sweeping robot base station and a cleaning equipment. Background Art

[0002] Some existing cleaning equipment includes a sweeping robot and a sweeping robot base station. The sweeping robot can move to various positions in the room for cleaning. The sweeping robot base station is generally stationary and is used for automatically charging, dust collection, cleaning, etc. of the sweeping robot, completely liberating the hands of users. Among them, when the sweeping robot base station collects dust or garbage from the sweeping robot, the dust and garbage mainly but not limited to come from two places: the dust and garbage in the dust collection box on the sweeping robot, and the dust and garbage washed from the cleaning components such as the mop and brush on the sweeping robot.

[0003] Therefore, multiple air ducts are usually arranged in the sweeping robot base station. The multiple air ducts are respectively arranged at different positions and are respectively used for sucking dust and garbage from different places. However, in some existing sweeping robot base stations, in order to ensure the suction force of each air duct during operation, each air duct is independently equipped with a fan, which results in a high production cost of the sweeping robot base station, and the overall volume and floor space are relatively large.

[0004] The above content is only used to assist in understanding the technical solution of the invention, and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main object of the present invention is to propose a sweeping robot base station, aiming to solve the technical problem that in some existing sweeping robot base stations, each air duct needs to be independently equipped with a fan, and thus the production cost of the sweeping robot base station is relatively high.

[0006] To achieve the above object, the sweeping robot base station proposed by the present invention includes a base station body, an air duct assembly, and a switch assembly. The base station body is provided with a cleaning chamber, the cleaning chamber has an opening for the sweeping robot to enter and exit, and a fan is also provided in the base station body. The air duct assembly is installed in the cleaning chamber and includes multiple air ducts. One end of each air duct is communicated with the fan, and the other end is communicated with the cleaning chamber. The switch assembly is installed in the cleaning chamber and includes a moving member and a driving member for driving the moving member to move. Under the drive of the driving member, the moving member selectively opens at least one of the multiple air ducts and closes the remaining air ducts.

[0007] In one embodiment, the floor sweeping robot has a cleaning component and a dust suction port, and the cleaning chamber further has a cleaning position for cleaning the cleaning component. The air duct assembly includes a first air duct and a second air duct. One end of the first air duct is communicated with the fan, and the other end faces the cleaning position; one end of the second air duct is communicated with the fan, and the other end is used for docking with the dust suction port.

[0008] The moving member moves in the cleaning chamber and has a first position and a second position; when the moving member is in the first position, the moving member opens the first air duct and closes the second air duct; when the moving member is in the second position, the moving member closes the first air duct and opens the second air duct.

[0009] In one embodiment, a switch groove is formed in the peripheral wall of the first air duct. The moving member is provided with a first switch position and a second switch position. A seal is installed at the first switch position, and the second switch position is in a semi-surrounding structure and is adapted to the outer periphery of the first air duct. When the moving member is in the first position, the second switch position covers outside the switch groove; when the moving member is in the second position, the seal is inserted into the first air duct from the switch groove to close the first air duct.

[0010] In one embodiment, a fixing portion is provided at the first switch position; the seal is provided with a receiving groove, and at least part of the fixing portion is wrapped in the receiving groove; and / or, a first clamping structure is provided on the fixing portion, and a second clamping structure for fitting and clamping with the first clamping structure is provided on the seal.

[0011] In one embodiment, one end of the second air duct for docking with the dust suction port is a dust extraction port with an upward opening. An air ventilation hose is installed at the dust extraction port, and the moving member is further provided with an air vent. When the moving member is in the first position, the air ventilation hose is tightly pressed below the moving member; when the moving member is in the second position, the air ventilation hose passes through the air vent and is connected to the dust suction port.

[0012] In one embodiment, the lower end of the air ventilation hose is hermetically clamped with the dust extraction port of the second air duct, and / or, the upper end of the air ventilation hose is provided with a sealing inclined surface, and the sealing inclined surface is in an annular structure and is used for abutting against the inner periphery of the dust suction port.

[0013] In one embodiment, the moving member is further provided with a positioning plane and an access inclined surface connected to one side of the positioning plane. The air vent is arranged on the positioning plane, and the lower side of the access inclined surface extends to the opening of the cleaning chamber.

[0014] In one embodiment, a plurality of anti-slip ridges are provided on the access slope, and / or a positioning groove is further provided on the positioning plane, and the positioning groove is used to accommodate and position the wheels of the floor sweeping robot.

[0015] In one embodiment, limiting surfaces are provided at both ends of the positioning plane and the access slope, and the first switch position and the second switch position are both located at one of the limiting surfaces; the distance between the two limiting surfaces is adapted to the width of the floor sweeping robot, so that the wheels of the floor sweeping robot can smoothly roll into the positioning groove.

[0016] In one embodiment, the driving member is of a mechanical hand structure and is installed in the base body, a driving part is provided on the moving member, and the driving member can grab the driving part and drive the moving member to move back and forth between the first position and the second position.

[0017] In one embodiment, the air duct assembly includes a fixed seat, an air duct fitting and a tee. The fixed seat is installed in the cleaning cavity and is used for installing the moving member, and a plurality of first grooves are provided on the fixed seat. The air duct fitting is installed on the fixed seat and is provided with a plurality of second grooves, and the plurality of first grooves and the plurality of second grooves jointly enclose the first air duct and the second air duct. The first air duct and the second air duct converge at the tee and are communicated to the fan through the tee.

[0018] The floor sweeping robot base station of the present invention is provided with a switch assembly, and the switch assembly includes a moving member and a driving member for driving the moving member to move. When it is necessary to make one of the plurality of air ducts work, the moving member can be driven to move to open the air duct, and at the same time, the remaining other air ducts are closed, so that the fan only performs corresponding work through this air duct, such as sucking dust and garbage, drying, etc. It can be understood that because the fan in the floor sweeping robot base station of the present invention only provides suction for a certain opened air duct, the suction of the opened air duct is ensured. And when it is necessary for other air ducts to work, the moving member can also be driven to move for switching to ensure the suction of each air duct.

[0019] Therefore, when each air duct in the floor sweeping robot base station of the present invention works, sufficient suction can be ensured through the switch assembly, and thus it is not necessary to separately equip a fan for each air duct, reducing the production cost of the floor sweeping robot base station, and reducing the overall volume and floor space of the floor sweeping robot base station.

[0032] As Figure 1 shown, the floor cleaning robot base station 10 is mainly used for supporting the use of the floor cleaning robot 20. The floor cleaning robot 20 has a cleaning component 21 and a dust suction port 22. Specifically, the cleaning component 21 of the floor cleaning robot 20 generally includes a mopping cloth, a brush, a roller brush, etc., and can thus clean the room. As the cleaning progresses, the cleaning component 21 of the floor cleaning robot 20 will become dirtier and dirtier. If not cleaned in time, it will cause the floor cleaning robot 20 to make the room dirtier while cleaning. The floor cleaning robot 20 also has a dust suction port 22, and the dust suction port 22 is generally located at the bottom of the floor cleaning robot 20 and faces the ground, and can thus suck the dust and garbage on the ground into the dust collection box communicated therewith. As the cleaning progresses, the dust collection box of the floor cleaning robot 20 will gradually be filled with dust and garbage. If not cleaned in time, it will also cause the floor cleaning robot 20 to be unable to continue cleaning. Or, as the cleaning progresses, the power of the floor cleaning robot 20 will gradually decrease, and it is also necessary to charge the floor cleaning robot 20 in time, etc.

[0033] The floor cleaning robot base station 10 can automatically charge, collect dust, clean, etc. the floor cleaning robot 20, without the user having to constantly pay attention to whether the dust and garbage in the floor cleaning robot 20 are full and clean it manually. The floor cleaning robot 20 can also automatically return to the floor cleaning robot base station 10 for charging when the power is about to run out, completely liberating the user's hands.

[0034] The cleaning component 21 and the dust suction port 22 of the floor sweeping robot 20 are generally located at different positions on the floor sweeping robot 20. The cleaning component 21 needs to be washed with water first, and then the dust and garbage washed down are sucked into the dust collection box in the floor sweeping robot base station 10. The dust and garbage in the dust collection box of the floor sweeping robot 20 can be directly sucked out and collected. Some existing floor sweeping robot base stations usually set multiple air ducts to suck dust and garbage from different places, or realize other functions such as drying through the air ducts. And in order to ensure the suction force of each air duct during operation, each air duct is independently equipped with a fan, which results in a relatively high production cost of the floor sweeping robot base station 10, and the overall volume and floor space are relatively large. Therefore, the present invention proposes a floor sweeping robot base station 10 to solve the above technical problems.

[0035] In an embodiment of the present invention, as Figures 1 to 3 shown, the floor sweeping robot base station 10 includes a base body 30, an air duct assembly 40 and a switch assembly 50. The base body 30 is provided with a cleaning cavity 31, and the cleaning cavity 31 has an opening for the floor sweeping robot 20 to enter and exit, and a cleaning position for cleaning the cleaning component 21. The cleaning cavity 31 is generally arranged at the lower part of the floor sweeping robot base station 10, and its opening is close to the ground, so that the floor sweeping robot 20 can conveniently enter and exit the cleaning cavity 31. After the floor sweeping robot 20 enters the cleaning cavity 31, the floor sweeping robot base station 10 can automatically clean, collect dust or charge the floor sweeping robot 20, etc. The cleaning position in the cleaning cavity 31 is mainly used for cleaning the cleaning component 21 of the floor sweeping robot 20. After the floor sweeping robot 20 enters the cleaning cavity 31, the cleaning position is correspondingly located below the cleaning component 21, so as to conveniently and quickly clean the cleaning component 21.

[0036] The cleaning position can be a cleaning tank structure. In addition, a clean water tank and a sewage tank connected to the cleaning position are also installed in the floor sweeping robot base station 10. The clean water tank provides clean water and cleans the cleaning component 21 of the floor sweeping robot 20, and the sewage tank is mainly used for collecting the sewage after cleaning. Of course, a controller, an automation device, etc. are also provided in the floor sweeping robot base station 10 to control and drive the floor sweeping robot base station 10 to automatically charge, clean, collect dust, etc. for the floor sweeping robot 20.

[0037] In addition, a fan is also provided in the base body 30. The fan is mainly used to provide suction force for the floor sweeping robot base station 10 to collect dust and garbage. Therefore, the fan is generally also connected to a dust collection box, and the dust collection box can also be installed in the floor sweeping robot base station 10. In one embodiment, the fan and the dust collection box are installed at the top of the floor sweeping robot base station 10, so that the user can conveniently remove the dust collection box and clean the garbage, and facilitate the disassembly, assembly and maintenance of the fan.

[0038] The air duct assembly 40 is installed in the cleaning chamber 31 and includes a plurality of air ducts. One end of each air duct communicates with the blower, and the other end communicates with the cleaning chamber 31. Specifically, one end of each air duct that communicates with the blower can be first integrated into a connecting pipe and then connected to the blower together, so as to reduce the internal space of the sweeping robot base station 10.

[0039] When the other end of each air duct communicates with the cleaning chamber 31, it can have different orientations or directions according to the functions to be achieved. For example, when a certain air duct is mainly used to suck the dust and garbage in the dust collection box on the sweeping robot 20, the opening of the air duct can be oriented towards the suction port of the sweeping robot 20. Or when another air duct is mainly used to suck the dust and garbage washed from the cleaning components of the sweeping robot 20, the opening of the air duct can be oriented towards the cleaning position in the cleaning chamber 31. Or when another air duct is mainly used to dry the sweeping robot 20, the opening of the air duct can be oriented towards the position of the sweeping robot 20 after it enters the cleaning chamber 31. Specifically, it can be set according to actual needs.

[0040] For example, in an embodiment, the air duct assembly 40 is installed in the cleaning chamber 31 and includes a first air duct 41 and a second air duct 42. One end of the first air duct 41 communicates with the blower, and the other end is oriented towards the cleaning position to suck the dust and garbage washed from the cleaning components 21 of the sweeping robot 20. It should be noted that since there will be running water or accumulated water at the cleaning position during cleaning, a waterproof switch or valve can be provided at the air duct opening of the first air duct 41, and the waterproof switch or valve is opened when sucking dust and garbage is needed. Or the cleaning position can be set as a sloped structure, and the air duct opening of the first air duct 41 is located at the top of the sloped structure to prevent accumulated water from flowing into the first air duct 41.

[0041] One end of the second air duct 42 communicates with the blower, and the other end is used to dock with the suction port 22 to suck and empty the dust and garbage in the dust collection box of the sweeping robot 20. The suction port 22 of the sweeping robot 20 is generally located at the bottom of the sweeping robot 20 and faces the ground, so the air duct opening of the second air duct 42 can be set upward and docked with the suction port 22 of the sweeping robot 20. Of course, when the suction port 22 of the sweeping robot 20 is set at other positions, the air duct opening of the second air duct 42 is adaptively set, as long as it can be docked with the suction port 22 of the sweeping robot 20.

[0042] It should be noted that the "one end and the other end" refer to the ports (or air duct openings). In addition, branches can be provided on the first air duct 41 or the second air duct 42 to facilitate uniform suction of dust and garbage. The forming methods of the first air duct 41 and the second air duct 42 are not limited, and they can be directly formed by pipes or assembled by multiple fittings.

[0043] For example, in one embodiment, Figure 2 As shown, the air duct assembly 40 includes a fixed seat 43, an air duct accessory 44 and a three-way pipe 45. The fixed seat 43 is installed in the cleaning chamber 31 and is used for the installation of the movable member 51. The shape, size, etc. of the fixed seat 43 are adapted to the cleaning chamber 31 so as to be stably installed in the cleaning chamber 31. At the same time, the fixed seat 43 can be appropriately set with a yield structure according to other structures (such as cleaning positions, etc.) in the cleaning chamber 31, which is convenient for installation and makes the structure of the sweeping robot base station 10 more compact. The fixed seat 43 is provided with a plurality of first grooves. The air duct accessory 44 is installed on the fixed seat 43 and is provided with a plurality of second grooves, and the plurality of first grooves and the plurality of second grooves jointly enclose the first air duct 41 and the second air duct 42. Specifically, the first groove and the second groove can be set to two respectively, wherein one first groove and one second groove enclose the first air duct 41, and another first groove and another second groove can enclose the second air duct 42.

[0044] The first air duct 41 and the second air duct 42 are converged into the three-way pipe 45 and are connected to the fan through the three-way pipe 45 , thereby improving the compactness of the internal structure of the cleaning robot base station 10 .

[0045] Please combine Figures 2 to 6 , the switch assembly 50 is installed in the cleaning chamber 31 and includes a moving member 51 and a driving member that drives the moving member 51 to move. The moving member 51, driven by the driving member, selectively opens at least one of the multiple air ducts and closes the remaining air ducts. For example, when it is necessary to make one of the multiple air ducts work, the moving member 51 can be driven to move and open the air duct, and the remaining other air ducts can be closed at the same time, so that the fan only performs corresponding work through the air duct, such as sucking dust and garbage, drying, etc. It can be understood that because the fan in the sweeping robot base station 10 of the present invention only provides suction for a certain air duct that is opened, the suction of the opened air duct is guaranteed. When other air ducts are needed to work, the moving member 51 can also be driven to move and switch to ensure the suction of each air duct.

[0046] In addition, when necessary, such as when drying and cleaning various parts of the cleaning chamber 31 itself through various air ducts, when too much suction is not needed, the moving member 51 can also open two or more air ducts at the same time. Or, when the suction force will not drop significantly and is sufficient for work, the moving member 51 can open two or more air ducts at the same time and close the remaining air ducts, and only the suction force and the normal operation of the air ducts need to be ensured.

[0047] For example, in one embodiment, the moving member 51 moves within the cleaning chamber 31 and has a first position and a second position; when the moving member 51 is in the first position, the moving member 51 opens the first air duct 41 and closes the second air duct 42; when the moving member 51 is in the second position, the moving member 51 closes the first air duct 41 and opens the second air duct 42.

[0048] In this embodiment, the material of the moving member 51 is not limited and can be made of plastic, metal, or composite material. The moving member 51 is placed within the fixed seat 43 and above the first air duct 41 and the second air duct 42. The moving member 51 can open and close the first air duct 41 and the second air duct 42 through its own structure, or by connecting with a seal 60, or by the combination of its own structure and the seal 60.

[0049] The moving member 51 can open and close the first air duct 41 (or the second air duct 42) by opening and closing the air duct opening of the first air duct 41 (or the second air duct 42), or can also open and close the first air duct 41 (or the second air duct 42) from the middle position of one air duct (or the second air duct 42), and can be specifically set according to needs.

[0050] For example, in one embodiment, please refer to Figure 2 and Figure 3 , a switch groove 411 is formed on the peripheral wall of the first air duct 41, and the switch groove 411 penetrates into the interior of the first air duct 41. The moving member 51 realizes the opening and closing of the first air duct 41 through the cooperation with the switch groove 411. Specifically, the moving member 51 is provided with a first switch position 511 and a second switch position 512. The first switch position 511 is installed with a seal 60, and the seal 60 is elastically compressible. The second switch position 512 has a semi-surrounding structure and fits the outer periphery of the first air duct 41.

[0051] When the moving member 51 is in the first position, the second switch position 512 covers the outside of the switch groove 411, and the inner peripheral surface of the second switch position 512 closely adheres to the outer peripheral surface of the first air duct 41. Further, the first air duct 41 is not blocked and is in a ventilated state, realizing the suction of dust and garbage, and being able to prevent dust and garbage from floating out from the switch groove 411. In order to ensure the sealing performance, an elastic sealing structure layer such as sponge or elastic sealant is further provided on the inner peripheral surface of the second switch position 512. Of course, an elastic sealing structure layer can also be correspondingly provided on the outer peripheral surface of the first air duct 41, or elastic sealing structure layers are provided on both the outer peripheral surface of the first air duct 41 and the inner peripheral surface of the second switch position 512 to ensure the sealing performance of the first air duct 41 on the peripheral wall.

[0052] It should be noted that the outer periphery of the first air duct 41 can be a circular structure, a square structure, an irregular special-shaped structure or other structures. The second switch position 512 is adaptively set according to the outer peripheral structure of the first air duct 41, and only needs to be able to better cover the switch groove 411 and avoid air leakage.

[0053] When the moving member 51 is in the second position, the seal 60 is inserted into the first air duct 41 from the switch groove 411 to close the first air duct 41. Specifically, the thickness of the seal 60 is slightly greater than the groove width of the switch groove 411. When the seal 60 is inserted into the switch groove 411, it is compressed and deformed, and then closely fits with the wall surface of the switch groove 411. At the same time, the part of the seal 60 located inside the first air duct 41 can abut against the inner peripheral surface of the first air duct 41, so as to seal the first air duct 41 and the switch groove 411 at the same time, realizing the closing of the first air duct 41.

[0054] It should be noted that when the pipe wall of the first air duct 41 is relatively thick, the part of the seal 60 extending into the first air duct 41 can be made smaller (here referring to the size) than the part of the seal 60 abutting against the switch groove 411. Or a rigid structure is provided inside the seal 60, and the size of the rigid structure is adapted to the inner periphery of the first air duct 41. Then, the seal 60 can be extruded into the first air duct 41 through the rigid structure and has a good abutting force with the inner peripheral surface of the first air duct 41 to ensure the sealing performance.

[0055] In order to enable the seal 60 to smoothly pass through the switch groove 411 and be inserted into the first air duct 41, in an embodiment, a fixing part 513 is provided on the first switch position 511, and the fixing part 513 is a rigid structure; a receiving groove 61 is provided on the seal 60, and at least part of the fixing part 513 is wrapped in the receiving groove 61. It can be understood that during the process of the moving member 51 switching to the first position, the fixing part 513 can push the seal 60 into the switch groove 411 and the first air duct 41, avoiding the situation that the seal 60 cannot be well inserted into the switch groove 411 due to insufficient rigidity.

[0056] In another embodiment, to ensure the stable connection between the seal 60 and the fixing part 513, a first clamping structure 514 is provided on the fixing part 513, and a second clamping structure 62 for adaptively clamping with the first clamping structure 514 is provided on the seal 60. Specifically, the first clamping structure can be a clamping hole, and the second clamping structure 62 can be a clamping protrusion. The outer diameter of the clamping protrusion can be slightly larger than the aperture of the clamping hole. When the clamping protrusion is clamped into the clamping hole, it undergoes elastic deformation, and then a large frictional force can be generated to prevent the seal 60 from falling off during the process of inserting into or disengaging from the switch groove 411.

[0057] In this embodiment, the moving member 51 inserts the seal member 60 into the switch groove 411 in a top-down manner. The fixing portion 513 includes an upper half and a lower half. The first clamping structure 514 is provided on the upper half, and the lower half is wrapped in the accommodation groove 61 on the seal member 60, so that while the fixing portion 513 is stably connected to the seal member 60, the seal member 60 can be quickly and conveniently inserted into or removed from the switch groove 411.

[0058] In addition, the switch groove 411 can also penetrate through the entire first air duct 41, and thus the first air duct 41 is divided into two sections. At this time, an annular sealing ring can be provided at the second switch position 512. The shape of the annular sealing ring is adapted to the switch groove 411 and is compressed in the switch groove 411 when the moving member 51 is in the first position. When the first moving member is in the second position, the first switch position 511 can still use a seal member to close the first air duct 41, and at this time the seal member 60 passes through the entire first air duct 41.

[0059] The above introduces an implementation manner of the moving member 51 for opening and closing the first air duct 41, that is, opening or closing the first air duct 41 through the switch groove 411. Of course, this implementation manner can also be applied to the second air duct 42 and other air ducts, that is, the moving member 51 also opens or closes the second air duct 42 and other air ducts through the switch groove 411. Only the corresponding positional relationship needs to be designed to ensure that when the moving member 51 is in the first position, the moving member 51 opens the first air duct 41 and closes the second air duct 42, and when the moving member 51 is in the second position, the moving member 51 closes the first air duct 41 and opens the second air duct 42.

[0060] Alternatively, the moving member 51 can also adopt other ways to open or close the second air duct 42. For example, in one embodiment, one end of the second air duct 42 for docking with the dust suction port 22 is a dust extraction port 421 with an upward opening. The dust extraction port 421 is provided with a ventilation hose 70. The ventilation hose 70 is connected to the second air duct 42 and extends out from the dust extraction port 421 of the second air duct 42. The moving member 51 is also provided with a ventilation port 515, and the size of the ventilation port 515 is large enough for the ventilation hose 70 to pass through.

[0061] When the moving member 51 is in the first position, the ventilation hose 70 is tightly pressed under the moving member 51 and seals the opening of the ventilation hose 70. Because the ventilation hose 70 is elastically compressed and abuts against the moving member 51, the moving member 51 closes the second air duct 42 by compressing the ventilation hose 70 on its own surface. And because the ventilation hose 70 is compressed, the sealing performance when closing the second air duct 42 is ensured.

[0062] When the moving member 51 is in the second position, the ventilation port 515 on the moving member 51 corresponds to the ventilation hose 70. The ventilation hose 70 is no longer compressed and resumes its elastic deformation, and can then pass through the ventilation port 515 and be connected to the dust suction port 22, ensuring that the second air duct 42 can smoothly empty the dust and garbage accumulated on the floor cleaning robot 20 through the dust suction port 22 of the floor cleaning robot 20 and collect them into the dust collection box on the floor cleaning robot base station 10.

[0063] In an embodiment, to ensure the airtightness of the second air duct 42 during ventilation, the lower end of the ventilation hose 70 is hermetically clamped to the dust extraction port 421 of the second air duct 42. Specifically, an annular clamping groove is provided on the outer periphery of the ventilation hose 70, and an annular clamping platform is provided at the dust extraction port 421 of the second air duct 42. The annular clamping groove and the annular clamping platform are hermetically clamped. A sealing inclined surface 71 is provided at the upper end of the ventilation hose 70. The sealing inclined surface 71 is in a ring structure and is used to abut against the inner periphery of the dust suction port 22 to prevent air leakage between the ventilation hose 70 and the dust suction port 22 of the floor cleaning robot 20.

[0064] In summary, it can be understood that when the first air duct 41 needs to work, the moving member 51 can be driven to move to the first position, so that the fan only sucks dust and garbage through the first air duct 41 to ensure the suction force; when the second air duct needs to work, the moving member 51 can be driven to move to the second position, so that the exhaust fan only sucks dust and garbage through the second air duct 42 to ensure the suction force. That is, each air duct in the floor cleaning robot base station 10 of the present invention can ensure sufficient suction force through the switch assembly 50 during operation, and thus there is no need to separately equip a fan for each air duct, reducing the production cost of the floor cleaning robot base station 10, as well as reducing the overall volume and floor space of the floor cleaning robot base station 10.

[0065] Of course, the floor cleaning robot base station 10 may also include a third air duct, a fourth air duct, etc., which will not be listed one by one here. For example, it further includes a third air duct. One end of the third air duct communicating with the cleaning chamber 31 is located on the side wall of the cleaning chamber 31 and is used to dry the floor cleaning robot 20. The opening and closing of the third air duct can be achieved in the same way as the opening and closing of the first air duct by the moving member 51, or in the same way as the opening and closing of the second air duct by the moving member 51, or set according to the actual situation.

[0066] In another embodiment, to facilitate the entry and exit of the floor cleaning robot 20 from the cleaning chamber 31 of the floor cleaning robot base station 10, the moving member 51 is further provided with a positioning plane 516 and an access inclined plane 517 connected to one side of the positioning plane 516. The ventilation port 515 is provided on the positioning plane 516, and the lower side of the access inclined plane 517 extends to the opening of the cleaning chamber 31. When the floor cleaning robot 20 moves from outside the floor cleaning robot base station 10 to the opening of the cleaning chamber 31, it can enter the cleaning chamber 31 along the access inclined plane 517 and be positioned on the positioning plane 516.

[0067] In this embodiment, when the floor cleaning robot 20 enters the cleaning chamber 31 and is located on the positioning plane 516, the dust suction port 22 of the floor cleaning robot 20 is opposite to the ventilation port 515 of the moving member 51, and the ventilation port 515 is offset from the dust extraction port 421 of the second air duct 42. That is, at this time, the moving member 51 is in the first position, the second air duct 42 is in the closed state, and the ventilation hose 70 at the dust extraction port 421 of the second air duct 42 is compressed under the moving member 51. At the same time, the first air duct 41 is in the open state but has not started working.

[0068] The floor cleaning robot base station 10 can first clean the cleaning component 21 on the floor cleaning robot 20 and drain the sewage generated during the cleaning. Then, the fan is turned on and the first air duct 41 starts to work to suck the dust and garbage washed down into the dust collection box of the floor cleaning robot base station 10.

[0069] After the dust and garbage washed down are sucked and collected cleanly, the moving member 51 can be switched to the second position by the driving member, the first air duct 41 is closed and the second air duct 42 is opened. At the same time, the moving member 51 drives the floor cleaning robot 20 to move together, so that the ventilation hose 70 at the dust extraction port 421 of the second air duct 42 passes through the ventilation port 515 and is connected to the dust suction port 22 of the floor cleaning robot 20, and then starts to discharge the dust and garbage in the dust collection box of the floor cleaning robot 20.

[0070] In one embodiment, to prevent the floor cleaning robot 20 from slipping during the upward movement along the access inclined plane 517, a plurality of anti-slip ridges 5171 are provided on the access inclined plane 517. The extending directions of the plurality of anti-slip ridges 5171 intersect with the moving direction of the floor cleaning robot 20 when it moves on the access inclined plane 517, and can be perpendicular to each other or at other crossing angles. The anti-slip ridges 5171 can be convex arc-shaped ridges, which can prevent slipping while avoiding hindering the movement of the floor cleaning robot 20.

[0071] In another embodiment, a positioning groove 5161 is further provided on the positioning plane 516. The positioning groove 5161 is used to accommodate and position the wheels of the sweeping robot 20, so as to ensure that the sweeping robot 20 can be stably positioned on the positioning plane 516, prevent the sweeping robot 20 from retreating, and ensure that the suction port 22 of the sweeping robot 20 accurately corresponds to the ventilation port 515 on the positioning plane 516.

[0072] In order to ensure that the wheels of the sweeping robot 20 can accurately roll into the positioning groove 5161 of the positioning plane 516, in one embodiment, limiting surfaces 518 are provided at both ends of the positioning plane 516 and the access inclined surface 517. The first switch position 511 and the second switch position 512 are both located at one of the limiting surfaces 518. The distance between the two limiting surfaces 518 is adapted to the width of the sweeping robot 20, so that the wheels of the sweeping robot 20 can smoothly roll into the positioning groove 5161. Of course, in order to prevent the sweeping robot 20 from getting stuck with the two limiting surfaces 518 during the process of entering the cleaning chamber 31, a guiding pulley structure such as a pulley, a guiding wheel 5181, or a universal wheel is provided on each limiting surface 518 to ensure that the sweeping robot 20 can smoothly enter and exit the cleaning chamber 31.

[0073] Regarding the switching manner of the moving member 51 between the first position and the second position, in this embodiment, the driving member first lifts the moving member 51 to a moving height, then drives the moving member 51 to move above the first position or the second position, and finally lowers the moving member 51 to realize the position switching of the moving member 51, that is, to realize the opening and closing of the first air duct 41 and the second air duct 42. Of course, according to the actual situation, the moving member 51 can also be set to switch positions in a combination form of moving, rotating, or other movements.

[0074] In this embodiment, the driving member can be located below the moving member 51 and lift the moving member 51 by a certain height, or the driving member can also be located above the moving member 51 and pull up the moving member 51 by a certain height. For example, in one embodiment, the driving member is a mechanical hand structure and is installed in the base body. A driving part 519 is provided on the moving member 51, and the driving part 519 can be a hook-shaped structure, so that the driving member can well grasp the driving part 519 and drive the moving member 51 to move back and forth between the first position and the second position.

[0075] The present invention also provides a cleaning device 80, which includes a sweeping robot 20 and a sweeping robot base station 10. The specific structure of the sweeping robot base station 10 refers to the above embodiment. Since this cleaning device 80 adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present invention.
