Description

Base station and cleaning system

Technical Field

The present utility model relates to the field of cleaning equipment, and in particular, to a base station capable of providing multifunctional services (including, but not limited to, mop changing, garbage cleaning, charging, fluid replacement, etc.) for cleaning robots including, but not limited to, floor sweeping robots, floor mopping robots, sweeping and mopping integrated robots, window cleaning machines, etc., and a cleaning system employing the base station.

Background

With the development of technology and the continuous pursuit of people for higher quality of life, household cleaning robots including but not limited to floor sweepers, floor mops, window cleaners and the like are increasingly popular with users because of the ability to help people liberate from heavy household labor.

Cleaning robots generally perform cleaning operations using a cleaning medium (e.g., paper towel, mop, etc.). As the cleaning operation time is prolonged, stains adhering to the cleaning medium are increased, and the cleaning effect is deteriorated. For this purpose, the dirty cleaning medium is removed and replaced with clean cleaning medium. In addition, the dust box carried by the cleaning robot collects various kinds of dust including dust during the cleaning operation. Similarly, dust collection in the dust box increases with the time of cleaning operation, and dust disposal or dust cleaning is also required.

Conventional cleaning robots typically require manual intervention to replace the cleaning media (including removal of dirty cleaning media, and installation of clean cleaning media) and to clean the dust box. The traditional mode of human intervention is not intelligent, the labor of a user is increased, hands are stained in the intervention process, and the user experience is poor.

Therefore, by improving the conventional base station which can only provide the charging function for the cleaning robot, the cleaning robot is returned to the base station, and then the base station is used for replacing the cleaning medium or cleaning the dust box of the cleaning robot, so that the cleaning robot is a mainstream technology development trend at present.

In fact, there are currently already base stations on the market that can provide cleaning robots with the service of exchanging cleaning media or cleaning dust boxes. However, it is noted that due to cleaning media replacement and dust box cleaning, corresponding receptacles (e.g., similar to the structure of a trash can) are provided to collect dirty cleaning media and dust/trash, respectively. The base station can provide limited space, so that the current base station generally only has one of the two functions of cleaning medium replacement and dust box cleaning. If a container is respectively arranged for cleaning medium replacement and dust box cleaning, the volume of the base station is increased, the structure of the base station is complicated, the problem of mutual interference possibly exists among all functional modules, and the reliability is poor.

The cleaning robot 400 in the embodiment of the present utility model may further include other necessary modules or components, such as a roll brush, a side brush, a suction port, etc., in order to realize the basic functions of the cleaning robot 400. It should be noted that any suitable existing configuration may be selected for the other necessary modules or components included in the cleaning robot 400. For the sake of clarity and brevity, the technical solutions provided by the present utility model will not be described in detail herein, and the drawings in the description are correspondingly simplified. It will be understood that the utility model is not limited in scope thereby.

As described above, the cleaning robot 400 according to the embodiment of the present utility model can be applied to cleaning situations including, but not limited to, sweeping, mopping, window wiping, dust collection, etc. In a specific scenario, the cleaning robot 400 of the embodiment of the present utility model may be a floor mopping robot, which drives the cleaning module 100 to contact with the ground, so as to wipe the ground.

It should be noted that, the above-mentioned scenario for mopping is only one possible cleaning operation scenario of the cleaning robot 400 according to the embodiment of the present utility model. Those skilled in the art will appreciate that the cleaning robot 400 of the present utility model may be extended for use in any suitable cleaning scenario, the embodiment of the present utility model is not limited thereto.

The floor mopping robot is mainly used as a scene. It will be appreciated from the foregoing that the scope of embodiments of the utility model is not limited thereby.

In various embodiments of the present utility model, the base station 200 includes a housing 203, a sidewall of the housing 203 near the bottom is provided with a first opening for the cleaning robot 400 to go in and out, a parking place 204 for parking the cleaning robot 400 is formed at the bottom, and the cleaning medium mounting apparatus 300 is provided on the housing 203. Since the clean cleaning medium is installed after the dirty cleaning medium installed on the cleaning module 100 is removed first. Accordingly, the housing 203 of the base station 200 is further provided with a trash can 201 for discharging and recycling dirty cleaning media.

In this embodiment, the trash can 201 is located above the park position 204 and can be used with a trash bag. The user can put the garbage bag in the garbage can 201, and after the garbage bag is full of garbage, the user takes out the garbage bag again and replaces the garbage can 201 with a new garbage bag. The upper edge of the trash can 201 may be mounted with dust-full detection means, such as an infrared sensor, an ultrasonic sensor, a distance sensor, etc., when the garbage is about to fill the garbage can 201, the dust-full detection device detects and alerts the user to empty. The base station 200 is provided with a suction device which is operated when the garbage bag is mounted in the garbage can 201, so that negative pressure is generated between the garbage bag and the inner wall of the garbage can 201, and the garbage bag is tightly attached to the inner wall of the garbage can 201. In a specific embodiment, the suction device may be a motor-driven fan that may be mounted to a side wall of the trash can 201. When the garbage bag is replaced, the fan is started to suck air inside the garbage can 201, so that the garbage bag can be attached to the inner wall of the garbage can 201. The power of the fan is far smaller than that of a wind pump of a traditional suction type dust collection base station, the noise is extremely low, and the fan is started only when the garbage bag is replaced.

In one embodiment, the garbage can 201 is movably disposed in the housing 203 along a horizontal direction, and the housing 203 is provided with a second opening corresponding to the sidewall of the garbage can 201, and the garbage can 201 has a third position capable of being moved out of the housing 203 through the second opening along the horizontal direction. Specifically, the inner wall of the housing 203 is provided with a horizontal rail, and the trash can 201 is provided on the horizontal rail. A horizontal driving assembly 205 connected with the garbage can 201 is arranged in the shell 203, and the garbage can 201 is driven to move in the horizontal direction by the horizontal driving assembly 205.

The horizontal driving assembly 205 comprises at least two rollers rotatably arranged on the inner wall of the housing 203, a synchronous belt surrounding the at least two rollers, and a motor for driving the rollers to rotate. The connecting line between at least two rollers is a horizontal line, and the garbage can 201 is fixedly connected with the synchronous belt. Thus, the motor drives the synchronous belt to rotate, and can drive the garbage can 201 to move horizontally together.

In an alternative embodiment, the dust-full detection device is communicatively coupled to a control module that controls the operation of the motor of the horizontal drive assembly 205. When the control module judges that the garbage in the garbage can 201 is full based on the detection result of the dust full detection device, the motor can be controlled to work, and the garbage can 201 is driven to horizontally move outwards to the outside of the shell 203, so that a user can conveniently take the garbage bag full of garbage, and replace the garbage bag with a new garbage bag. The base station 200 may be provided with a reset button in communication with a control module, and after the garbage bag is replaced, a user may trigger the reset button, and the control module controls the motor to rotate, so as to drive the garbage can 201 to move horizontally inwards into the housing 203. Then, the control module controls the suction device (fan) to be turned on again, so that the garbage bag is flattened and attached to the inner wall of the garbage can 201.

The base station 200 includes a consumable cartridge on an upper portion, which houses required consumables including a trash bag, a supply module described below. As shown in fig. 1, the upper portion of the housing 203 may be provided with a receiving groove in which a garbage bag 206 in a roll shape may be placed.

In the horizontal direction, the depth of the trash can 201 is smaller than that of the base station 200. In a preferred embodiment, the depth of the trash can 201 is about half the depth of the base station 200. In this way, the trash can 201 can move horizontally within the housing 203 and between a first position and a second position. Likewise, movement of the trash can 201 within the housing 203 is also driven by the horizontal drive assembly 205.

In the present embodiment, the first position is a position near the first opening/second opening, that is, a position on the right side of the housing 203. The second position is a position away from the first opening/second opening, i.e., a position to the left of the housing 203. It is noted that when the trash can 201 is returned from the third position into the housing 203, the trash can 201 is generally in the first position. At this time, the right outer wall of the trash can 201 is substantially flush with the outer wall of the housing 203, so that the overall appearance of the base station 200 is flat, and has an aesthetic and comfortable appearance. When the left outer wall of the trash can 201 contacts the inner wall of the housing 203, the trash can 201 is substantially in the second position.

The following describes the complete process of replacing the trash can 201 by the base station 200 according to the embodiment of the present utility model with reference to fig. 7A to 7E.

As shown in fig. 7A, the horizontal drive assembly 205 drives the garbage can 201 horizontally out of the housing 203.

As shown in fig. 7B, the user removes the pressing ring 207 at the mouth of the trash can 201, and removes the trash bag filled with trash.

As shown in fig. 7C, the user removes a new trash bag from the consumable cartridge of the base station 200 and nests into the trash can 201.

As shown in fig. 7D, the user puts the pressing ring 207 back into the mouth of the trash can 201 to press the trash bag.

As shown in fig. 7E, the horizontal drive assembly 205 drives the garbage can 201 horizontally back into the housing 203, and then the suction device is activated to flatten the garbage bag against the inner wall of the garbage can 201.

The first clamping module 700 is disposed in the housing 203 and corresponds to the first position for clamping the cleaning module 100. The first clamping module 700 and the carrying mechanism 208 mentioned below can refer to the description of the known embodiment with publication number W2020224542A1, and this embodiment only describes the portion related to the present utility model, and other portions will not be described in detail.

The first clamping module 700 includes a first bracket, and a first clamping structure provided on the first bracket for clamping the cleaning module 100. The first clamping structure includes: two first clamping members 701 which are oppositely arranged, and a first power source which drives the two first clamping members 701 to move in opposite directions. In this embodiment, the first clamping member 701 may have a jaw structure having a hook-shaped outer end so that the cleaning module 100 may be clamped from both ends.

In an alternative embodiment, as shown in fig. 8, the first power source may include: a motor, and an eccentric 702 driven by the motor. The eccentric 702 contacts the first clamping member 701, driving the first clamping member 701 to move inward to clamp the cleaning module 100, or to move outward to release the cleaning module 100. In this embodiment, the two first clamping members 701 are disposed opposite to each other and are located on the same line, the opposite ends of the two first clamping members 701 are provided with hollow ring bodies 703, and the eccentric wheel 702 is accommodated in the ring bodies 703. In addition, in order to guide and limit the movement of the two first clamping members 701, a guide member 704 may be provided on the first bracket, a guide groove 705 may be provided on the two first clamping members 701, the guide groove 705 may extend in a horizontal direction, and the guide member 704 may be embedded in the guide groove 705. It is noted that the eccentric points of the two eccentrics 702 (i.e. the connection points of the eccentrics 702 to the motor output shaft) are symmetrically arranged. Thus, by driving the two eccentric wheels 702, the two first clamping members 701 can be simultaneously driven to move inwards or outwards.

Of course, the first power source for driving the two first clamping members 701 to move in opposite directions may also adopt any other suitable configuration, and is not limited to the above-described embodiment. In another alternative embodiment, two first clamping members 701 may be arranged in parallel, with the opposite surfaces being provided with racks. The first power source may include: a motor, and a gear driven by the motor, the gear being meshed with the two racks. Alternatively, in yet another alternative embodiment, the first power source may be a hydraulic rod, a pneumatic rod, an electric telescopic rod, or the like, connected to the inner end of the first clamping member 701, and driving the first clamping member 701 to move inwards or outwards in the horizontal direction on the first support.

Further, an auxiliary clamping assembly may be further provided on the first clamping module 700. Specifically, the auxiliary clamping assembly may be an electromagnet on the first bracket, and the cleaning module 100 is provided with a magnetizable element. When the carrying mechanism 208 carries the cleaning module 100 to move upwards to approach the first clamping module 700, the electromagnet is electrified to generate a magnetic field, the cleaning module 100 is actively attracted to the lower end of the carrying mechanism under the action of magnetic attraction, and then the cleaning module 100 is clamped by the first clamping structure. When the cleaning module 100 completes the replacement of the cleaning medium, the electromagnet de-energizing magnetic field disappears, the first clamping structure is released, and the cleaning module 100 falls on the carrying mechanism 208 under the action of gravity.

The first clamping module 700 is provided with a first actuating assembly (not shown) for opening the cleaning module 100 to release the cleaning medium, the first actuating assembly cooperating with an opening actuator in the cleaning module 100. Specifically, the first actuating assembly includes a first motor, a first cam coupled to an output shaft of the first motor, and the first cam contacts a force-receiving end of a lever provided on the cleaning module 100. In this way, the first motor drives the first cam to rotate, so that the force application operation on the stressed end of the lever is realized, and the cleaning module 100 is opened.

As shown in fig. 1 to 7E, the carrying mechanism 208 corresponds to the first position, that is, corresponds to the first clamping module 700, and is used for carrying the cleaning module 100 to move in the vertical direction, where the movement range is between the parking position 204 and the first clamping module 700. In this embodiment, the carrying mechanism 208 includes a base tray for carrying the cleaning module 100 and a lifting assembly for driving the base tray to move in a vertical direction within the housing 203. The lifting assembly may include a belt structure such as a synchronous belt and a driving belt vertically arranged in the housing 203, and a step wheel is respectively arranged in the housing 203 near the upper end and the bottom, the synchronous belt and the driving belt are wound outside the two synchronous wheels, and the bottom plate tray is fixed on the vertical section of any side of the synchronous belt and the driving belt.

As described above, the first clamping module 700 is detachably attached to the cleaning module 100. When the carrier 208 carries the cleaning module 100 up to the first clamping module 700, the first clamping module 700 secures the cleaning module 100 thereto, and the carrier 208 moves back down to the park position 204. When the cleaning module 100 completes the replacement of the cleaning module 100, the carrying mechanism 208 moves up to the first clamping module 700 to receive the cleaning module 100, specifically, the first clamping module 700 releases the cleaning module 100 onto the carrying mechanism 208, and the carrying mechanism 208 then carries the cleaning module 100 to move down to the parking position 204.

Since the dustbin 201 is movable in a horizontal direction within the housing 203, the dustbin 201 is in a second position when the carrying mechanism 208 is moved in a vertical direction (including carrying the cleaning module 100 up or down) in order not to interfere with the movement of the cleaning module 100, thereby making room for the movement of the cleaning module 100. And when the trash can 201 is in the first position (specifically, the first clamping module 700 carries the cleaning module 100 to move down into the trash can 201 for removing the dirty cleaning medium), the carrying mechanism 208 is located in the parking position 204 to make room for the movement of the trash can 201.

In one embodiment, the base station 200 further includes a first conveying mechanism 209 disposed in the housing 203, and in this embodiment, the first conveying mechanism 209 may refer to the carrying mechanism 208, or may be configured of a plurality of pulleys, synchronous belts, conveyor belts, and the like. The first clamping module 700 is fixed on the first conveying mechanism 209, and can be driven by the first conveying mechanism 209 to have at least a degree of freedom of movement in a vertical direction. When the first clamping module 700 is driven to move upwards, the garbage can 201 is located at the second position. When the first clamping module 700 is driven to move downwards, the garbage can 201 is located at the first position.

The first conveying mechanism 209 drives the first clamping module 700 to move downward, so as to cooperate with the carrying mechanism 208 to receive the cleaning module 100, thereby ensuring that the cleaning module 100 can be transferred smoothly. That is, when the carrying mechanism 208 carries the cleaning module 100 to move upwards, the first conveying mechanism 209 also drives the first clamping module 700 to move downwards. When the cleaning module 100 approaches or contacts the first clamping module 700, the cleaning module 100 is automatically adsorbed at the lower end of the first clamping module 700 under the action of the auxiliary clamping assembly, and the cleaning module 100 is clamped by the first clamping structure. Then, the first conveying mechanism 209 drives the first clamping module 700 to move upwards to a position higher than the upper end of the garbage can 201, and the carrying mechanism 208 moves downwards to drive the bottom plate tray to return to the parking position 204.

The first conveying mechanism 209 drives the first clamping module 700 to move downwards, so that the cleaning module is as close to the garbage can 201 as possible, and the discharged dirty cleaning medium can smoothly enter the garbage can 201. Specifically, after the floor tray returns to the parking position 204, the first conveying mechanism 209 drives the first clamping module 700 to move downward, and the cleaning module 100 approaches the upper inlet of the dustbin 201. As can be seen from the above, in order to replace the cleaning medium, the dirty cleaning medium originally carried by the cleaning module 100 is removed, and then the clean cleaning medium is mounted on the cleaning module 100 by the cleaning medium mounting device 300. Therefore, in order to accomplish the removal and installation of the cleaning medium on the base station 200, the base station 200 should be further provided with a mechanism for connecting the cleaning medium recycling device and the cleaning medium installation device, specifically as follows:

In this embodiment, the first transfer mechanism 209 includes a vertical transfer section 2091 and a horizontal transfer section 2092 that are connected. The first clamping module 700 is driven into vertical movement toward or away from the trash can 201 as it moves to the vertical transfer section 2091, which, as explained above, is to receive the cleaning module 100 and remove dirty cleaning media.

A second clamping module 800 for clamping the dust box 600 is further disposed in the housing 203 corresponding to the second position, and the second clamping module 800 is configured to detachably clamp the dust box 600 as described above with respect to the first clamping module 700. Specifically, the second clamping module 800 includes a second bracket, and a second clamping structure disposed on the second bracket for clamping the dust box 600. The second clamping structure comprises two second clamping pieces which are oppositely arranged and a second power source which drives the two second clamping pieces to move along opposite directions. In this embodiment, the second clamping structure may refer to the description of the first clamping structure above, which is not described herein.

As shown in fig. 6A to 6L, the lower end of the dust box 600 is provided with an opening for dumping dust or garbage, and the lower folder 24 is rotatably provided at the lower end of the dust box 600, and is operable to close or open the lower end opening of the dust box 600. A second torsion spring is provided between the lower flap 24 and the dust box 600, and the torsion force applied to the lower flap 24 by the second torsion spring has a tendency to maintain a closed state or move toward a closed state.

A second actuating assembly for opening the lower flap 24 of the dust box 600 to release the dust is provided on the second clamping module 800. In an alternative embodiment, the second actuating assembly includes a second motor, a second cam coupled to the output shaft of the second motor, the second cam being in contact with the lower clamshell 24. The second motor drives the second cam to rotate, so that the force application operation on the lower flip cover 24 is realized, and the lower flip cover 24 is opened. Further, the lower folder 24 includes a mating portion 601 located in the dust box 600, and the mating portion 601 is located at a rotational connection side of the lower folder 24 and the dust box 600. The dust box 600 is rotatably provided with a link 602, and the lower end of the link 602 is in contact with the mating part 601 and the upper end is in contact with the second cam. When the potential energy high point of the second cam contacts with the upper end of the linkage 602, the linkage 602 is driven to rotate downward, thereby pushing the engaging portion 601 to open the lower folder 24. When the second cam rotates to a low potential energy point to contact with the upper end of the linkage 602, the mating part 601 is rotated upward to be restored under the action of the second torsion spring.

In this embodiment, the second clamping module 800 may be driven by the second conveying mechanism 210 to move along the vertical direction, and the second conveying mechanism 210 may refer to the carrying mechanism 208, which is not described herein. Similarly, in order not to interfere with the movement of the dust box 600, the dustbin 201 is located in the first position when the second clamping module 800 is driven to move downward to clamp the dust box 600 and when the second clamping module 600 is driven to move upward, thereby freeing up space for the movement of the dust box 600. When the second clamping module 800 clamps the dust box 600 to move upwards to a position where the dust box 600 is higher than the upper end of the dustbin 201, the dustbin 201 is switched from the first position to the second position to receive the garbage poured out of the dust box 600.

The main body 401 of the cleaning robot 400 is provided with a locking mechanism for locking the dust box 600 and an unlocking member linked with the locking mechanism, and the second clamping module 800 is provided with an operating member which is operatively matched with the unlocking member. When the second clamping module 800 moves downward in no load, the operating member is in a first state in which it can be engaged with the unlocking member. The locking structure releases the lock on the dust box 600 by the time the operating member is engaged with the unlocking member. When the second clamping module 800 clamps the dust box 600 to move downward, the operating member is in a second state of not being engaged with the unlocking member. By the time the dust box 600 is loaded into the host 401, the second clamping module 800 applies a downward force to the dust box 600 and the locking structure locks the dust box 600.

The locking and unlocking of the dust box 600 may be described below.

As shown in fig. 2 to 5, in another alternative embodiment, the cleaning robot 400 may include a cover opening device 15, and the cover opening device 15 may be fixedly installed to the dust box 600 so as to be transferred together with the dust box 600. The dust box 600 includes an upper folder 23 and a lower folder 24 (box cover), the upper folder 23 being operated by a person to open or close the dust box 600, and the lower folder 24 being operated by the cover opening device 15 to open or close the dust box 600. The upper folder 23 may be located at the upper surface of the dust box 600, and the lower folder 24 may be located at the lower surface of the dust box 600, thereby facilitating manual and automatic opening. There may also be a filtering component 220 within the dust box 600, the filtering component 220 filtering the sucked-in dust when the cleaning robot 400 is operated. The filter element 220 may include a HEPA filter, a foam pad, a nonwoven fabric, or the like.

The cover opening device 15 comprises a cover opening motor and a rotating part, wherein the rotating part comprises a synchronous pulley 151, a tension pulley 152 and a synchronous belt 153, the output end of the cover opening motor can be provided with the synchronous pulley 151, the synchronous pulley 151 and the tension pulley 152 are connected through a synchronous belt 153, and the cover opening motor drives the rotating part to rotate, namely, the synchronous pulley 151 and the tension pulley 152 are driven to rotate and drive the synchronous belt 153 to roll. The door motor may be mounted to the dust box 600 and the rotating part may be mounted to the lower folder 24 of the dust box 600. The cover opening device 15 is fixedly installed with the dust box 600, so that the cover opening device 15 is reliably connected with the dust box 600. When the dust box 600 moves to the dust collection port of the dust collection device 16, the cover opening motor drives the rotation part to rotate to open the lower folder 24. When the dust box 600 finishes dumping the garbage, the cover opening motor drives the rotating part to rotate so as to close the lower flip cover 24.

In other embodiments, the cover opening device 15 may further include a linkage mechanism disposed in the dust box 600, and the second clamping module 800 clamps the dust box 600 and then opens and closes the lower cover 24 by acting on the linkage mechanism.

The dust box 600 is provided with a lock pin 27 and a linkage 29, and the main body 401 of the cleaning robot 400 is provided with a lock groove, which constitutes the lock mechanism with the lock pin 27. When the operating member engages the interlocking portion 29 and pushes the interlocking portion 29 in the horizontal direction, the lock pin 27 can interlock with the interlocking portion 29 to withdraw from the lock groove. The interlocking portion 29 has a lock spring 26 connected to the lock pin 27. For example, the linkage 29 may be located downstream of the lock pin 27 in the inbound direction, and the linkage 29 may be moved in opposite directions simultaneously with the lock pin 27 in the horizontal direction.

When the second clamping module 800 is combined with the dust box 600, the operating member clamps the linkage part 29 and can push the linkage part 29 along the outbound direction, the locking spring 26 is compressed when the linkage part 29 moves, and the locking pin 27 moves along the inbound direction and exits the locking groove (as shown in fig. 3) in linkage with the linkage part 29. When the second clamping module 800 releases the dust box 600, the operating member releases the linkage 29, and the elastic force of the locking spring 26 ejects the locking pin 27 in the outbound direction, and the locking pin 27 is inserted into the locking groove.

As shown in fig. 5, the cleaning robot 400 includes an operating part capable of assisting the separation of the dust box 600 from the main body 401 or mounting to the main body 401 in response to a user pressing or releasing the pressing. Specifically, when the dust box 600 is opened manually, for example, the button 211 (operation portion) is pressed in the direction of arrow a, so that the lock spring 26 is compressed, the interlocking portion 29 moves and the lock pin 27 is driven by the switching mechanism 212, and the switching mechanism 212 brings the interlocking portion 29 and the lock pin 27 close. For example, the interlocking portion 29 moves in the direction of arrow B2, and the lock pin 27 moves in the direction of arrow B1, so that the lock pin 27 is retracted to be unlocked from the host 401.

The dust box 600 has a coupling groove, which is upwardly opened, the main body 401 has an upwardly open mouthpiece from which the dust box 600 exits the main body 401. The operating member is able to enter the coupling slot and grip the dust box 600, and after gripping the dust box 600, the operating member moves vertically along the first transfer mechanism 209. The operator can apply force to the dust box 600 to withdraw the lock pin 27 from the lock groove to assist in separating the dust box 600 from the host 401, and can release the force applied to the lock pin 27 to insert the lock pin 27 into the lock groove to assist in mounting the dust box 600 to the host 401.

The following is a process in which the base station 200 cleans the dust box 600 for the cleaning robot 400 in conjunction with fig. 6A to 6L.

As shown in fig. 6A, the cleaning robot 400 enters the base station 200 through the first opening. At this time, the second clamping module 800 and the trash can 201 are located at the second position, and the second clamping module 800 is higher than the trash can 201.

As shown in fig. 6B, the horizontal drive assembly 205 drives the trash can 201 to move to the first position, making room for movement of the second clamping module 800.

As shown in fig. 6C, the second conveying mechanism 210 drives the second clamping module 800 to move downward, the operating member unlocks the dust box 600, and then the second clamping structure clamps the dust box 600.

As shown in fig. 6D, the second conveying mechanism 210 drives the second clamping module 800 to move upwards, and the dust box 600 is driven upwards.

As shown in fig. 6E, the horizontal drive assembly 205 drives the trash can 201 to a second position and below the dust box 600.

As shown in fig. 6F, the second conveying mechanism 210 drives the second clamping module 800 to move downward a distance, so that the dust box 600 enters the garbage can 201 through the upper opening.

As shown in fig. 6G, the second performing component operates to open the lower folder 24 of the dust box 600 to complete the dust pouring operation.

As shown in fig. 6H, the second executing component resets, the lower cover 24 covers the opening at the lower end of the dust box 600 again under the action of the second torsion spring, the second conveying mechanism 210 drives the second clamping module 800 to move upwards, and the dust box 600 is driven to move upwards together until the dust box 600 is higher than the upper end of the dustbin 201.

As shown in fig. 6I, the horizontal drive assembly 205 drives the trash can 201 to move to the first position.

As shown in fig. 6J, the second conveying mechanism 210 drives the second clamping module 800 to move downward, loads the dust box 600 into the host 401, and applies downward force, so that the dust box 600 is locked on the host 401.

As shown in fig. 6K, the second conveying mechanism 210 drives the second clamping module 800 to move upwards, and returns to the initial position, where the second clamping module 800 is higher than the upper end of the dustbin 201.

As shown in fig. 6L, the horizontal drive assembly 205 drives the trash can 201 to reset to the second position.

In various embodiments of the present utility model, the trash can 201 is in the first position when the first actuating assembly of the first clamping module 700 opens the cleaning module 100. The trash can 201 is in the second position when the second actuating component of the second clamping module 800 opens the lower flap 24 of the dust box 600. Thus, the trash can 201 is driven to be positioned at a corresponding position according to actual needs to receive dirty cleaning media or dust. Thus, the base station 200 can realize two functions of cleaning medium replacement and dust box 600 cleaning at the same time by only configuring one garbage can 201, and the structure is remarkably simplified under the condition that the base station 200 realizes multiple functions.

In addition, as shown in fig. 1 to 7E, the consumable bin of the base station 200 is further provided with a water supplementing tank 213, a water supplementing connector 214 close to the bottom and communicated with the water supplementing tank 213 through a pipeline is arranged in the base station 200, and the water supplementing connector 214 is used for being in butt joint with a water inlet connector at the front end of the cleaning robot 400, so that the liquid supplementing operation of the cleaning robot 400 is realized.

In addition, the base station 200 includes a charging device provided on the docking station 204, and a charging connector is provided at the bottom of the cleaning robot 400, and the charging device is electrically connected with the charging connector to charge the cleaning robot 400. The charging device may include a metal contact and the charging connector may include a metal contact that mates with the metal contact of the charging device. When the cleaning robot 400 is driven into the base station 200 and parked on the parking place 204, the charging connector is docked with the charging device, so that the cleaning robot 400 can be charged.

The base station 200 has many structural components, among which no electrical components are spent. Thus, the reliability of the operation of these components will directly relate to the service life of the base station 200. Since dust emission may occur due to replacement of the cleaning medium and cleaning of the dust box 600, it is necessary to perform dust emission prevention treatment on the base station 200.

In an alternative embodiment, as described above, the first clamping module 700 may be configured to clamp the cleaning module 100 with the dirty cleaning medium downwardly into the dustbin 201 when the dustbin 201 is in the first position. When the trash can 201 is in the second position, the second clamping module 800 may drive the dust box 600 to move downward into the trash can 201. Thus, the dust in the dust box 600 and the dust can be discharged from the dust can 201, and the dust can be prevented from being raised.

Of course, in other alternative embodiments, the removal of dirty cleaning medium and the dumping of dust in the dust box 600 may be performed not within the receptacle 201, but above the receptacle 201, or at the upper inlet of the receptacle 201. Since dust fall is the most likely problem to be raised, in this case, a dust suppression assembly may be provided in the base station 200 for at least partially suppressing the raised dust when the second clamping module 800 opens the dust box 600.

In a specific embodiment, the dust suppression assembly may include a seal (e.g., rubber ring) disposed in the upper inlet of the trash can 201, and the outer contour of the second clamping module 800 (specifically the second bracket) is shaped to fit the upper inlet of the trash can 201. In this way, the seal may conform to the outer wall of the second clamping module 800 when the second clamping module 800 is in the access opening of the trash can 201. Therefore, when dust is poured, the upper end opening of the dustbin 201 is sealed, and the dust emission problem is preferably avoided.

To further enhance the dust suppression effect, the peripheral wall of the second clamping module 800 (specifically, the second bracket) may also be provided with a ring of sealing member, and the sealing member keeps interference contact with the sealing member on the inlet of the upper end of the dustbin 201, so as to further ensure that a small amount of dust raised through the first sealing structure cannot enter the base station 200.

Alternatively, in another embodiment, a foldable cover is provided within the base station 200. When in the deployed state, the cover at least partially covers the upper inlet of the trash can 201. The cover is in a folded state when the dirty cleaning medium is removed or the dust box 600 is cleaned. In this embodiment, the cover is provided on the trash can 201 and moves with the trash can 201. When the first clamping module 700 clamps the cleaning module 100 carrying the dirty cleaning medium to move downward or the second clamping module 800 clamps the dust box 600 to be cleaned to move downward, the cover member may be pushed to fold by the cleaning module 100 or the dust box 600, thereby exposing the upper inlet of the trash can 201. When the removal of the dirty cleaning medium is completed, the first clamping module 700 clamps the cleaning module 100 to move upward, or the second clamping module 800 clamps the cleaned dust box 600 to move upward beyond the cover member, the cover member returns to the unfolded state, at least partially covering the upper inlet of the trash can 201. The cover covers the upper inlet of the trash can 201 when the dirty cleaning medium is not discharged and the trash is not dumped, preventing the odor and dust from overflowing.

Further, when the cleaning robot 400 exchanges the cleaning medium, dirty cleaning media tend to accumulate a certain amount of dust. When the cleaning robot 400 enters the base station 200 to discharge the cleaning module 100 carrying the dirty cleaning medium, dust may fall off in the base station 200. To avoid dirt to stay and pollute the new mop, the parking place 204 of the base station 200 is provided with a hollowed-out plate at the position where the cleaning module 100 is placed, a collecting box is arranged below the hollowed-out plate, and dust falls down to the collecting box from the hollowed-out position, so that further pollution is avoided. Meanwhile, the collecting box can be pulled out, so that a user can clean the dust at regular intervals.

As can be seen from the foregoing, the cleaning module and the dust box of embodiments of the present utility model share a single dustbin 201. The single dustbin 201 may be operable to collect refuse dumped by the cleaning media and dust box commonly used for removal by the cleaning module in other ways including, but not limited to, the embodiments of the present utility model described above. It should be noted that the above-mentioned "other modes" are all included in the protection scope of the embodiments of the present utility model as long as they are made under the direction of the technical spirit of the exemplary embodiments of the present utility model.

It should be noted that, in the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and to distinguish between similar objects, and there is no order of preference between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

The foregoing is merely a few embodiments of the present utility model and those skilled in the art, based on the disclosure herein, may make numerous changes and modifications to the embodiments of the present utility model without departing from the spirit and scope of the utility model.
