Abstract

The utility model relates to a cleaning system. The cleaning system sets the relative positions of a dust box and a recycling box so that a recycling fan can provide a recycling airflow for recycling and cleaning dirt in the dust box without passing through a recycling air duct or only through a shorter recycling air duct. On the one hand, the setting of a bent air duct between the recycling box and the dust box is avoided. On the other hand, while the recycling fan provides recycling power, the power loss of the recycling fan is avoided. A recycling fan with a power lower than 550W can be used instead of a high-power recycling fan, which can not only ensure the cleaning efficiency of the cleaning system, but also effectively reduce the operating noise of the base station when performing dirt recycling and cleaning, so that the noise rise power of the cleaning system during operation can be reduced to below 80dB(A). At the same time, by setting the base to extend obliquely, the floor space occupied by the cleaning system in the horizontal direction can be effectively reduced, which facilitates the miniaturization design of the cleaning system.

Background Art

With the advancement of science and technology and the development of society, smart home appliances have gradually entered people's lives. Smart cleaning systems, as a smart home appliance that can sweep and mop the floor, are increasingly widely used in people's lives because they can automatically clean the floor.

However, although the intelligent cleaning system can realize automatic cleaning of the floor, the dust and debris sucked into the robot need to be recovered and processed through the suction force generated by the dust collecting fan in the base station. At this time, the dust collecting fan needs to overcome the resistance of the air duct and other structures in the air duct to realize the collection of dust and debris inside the body, resulting in a large operating noise when the intelligent cleaning system collects dust and debris, reducing the user-friendliness of the intelligent cleaning system.

In view of this, it is necessary to propose a new intelligent cleaning system to solve the above problems.

Please refer to Figures 1 to 3, which are a cleaning system provided in a preferred embodiment of the utility model. The cleaning system is used to clean the ground, and includes a base station 1, a robot 2 that can be detachably docked in the base station 1, and a recovery component 3. Among them, the base station 1 is used to provide a docking position for the robot 2 and provide a corresponding installation and setting space for the recovery component 3; the robot 2 can realize the cleaning task of the working area according to the preset operation logic, and can dock in the base station 1 when completing/terminating the cleaning task, so as to communicate with the recovery component 3 and/or other maintenance components housed in the base station 1 to complete maintenance work such as charging and water replenishment; the recovery component 3 is housed in the base station 1, and is used to recycle and clean the dirt collected by the robot 2 to ensure the endurance of the robot 2.

As shown in Figures 4 to 6, the base station 1 includes a housing 11 and a base 12 for the robot 2 to dock. The housing 11 is used to protect the base 12, the recovery component 3, the maintenance component and the robot 2 docked on the base 12 contained therein, and facilitates the overall installation and cleaning of the cleaning system.

The base 12 is arranged in the shell 1 to provide a docking position for the robot 2 to dock. Specifically, the base 12 is configured to separate the robot 2 and the recovery component 3 along its extension direction. In this embodiment, the base 12 is arranged obliquely in the shell 11, and the shell 11 and the base 12 are jointly enclosed to form a receiving space. The recovery component 3 is received in the receiving space and is located below the base 12. When the robot 2 docks on the base 12, the projections of the robot 2 and the recovery component 3 on the horizontal plane at least partially overlap; such a configuration can effectively reduce the floor space occupied by the cleaning system on the horizontal plane, and realize the miniaturized design of the cleaning system.

The docking position in the present invention is specifically a parking position where the robot 2 can be temporarily or stop for a while and can complete the corresponding dirt recovery and cleaning as well as charging, water replenishment and other maintenance work.

Furthermore, the angle between the base 12 and the horizontal plane is between 30° and 60°, so that the receiving space has a larger spatial volume, so that the recovery component 3 contained in the receiving space has a larger volume while ensuring that the base station 1 has a smaller footprint in the horizontal direction, so that the recovery component 3 can recover and clean the dirt generated by the robot 2 for multiple cleanings, effectively reducing the cleaning frequency of the recovery box 31 and improving the user-friendliness of the cleaning system. Preferably, the angle between the base 12 and the horizontal plane is 45°.

The base 12 is also provided with a connection port 121 and a positioning structure 122 staggered with the connection port 121. When the robot 2 is docked on the base 12, the robot 2 and the recovery component 3 are connected through the connection port 121, so that the recovery component 3 can complete the recovery and cleaning of the dirt collected in the robot 2 through the connection port 121.

The positioning structure 122 is used to transmit a positioning signal so that the robot 2 can accurately find the location of the base station 1. In this embodiment, the positioning structure 122 is an infrared positioning component, and the robot 2 is provided with an infrared receiving device corresponding to the infrared positioning component 122. When the robot 2 needs to return to the base station 1 to recycle and clean the dirt and/or perform maintenance work, the infrared receiving device can accurately find the infrared positioning signal emitted by the infrared positioning component 122, so that the robot 2 can smoothly enter the base station 1 and dock at the docking position of the base 12.

Please refer to Figures 6 to 8. In order to facilitate the robot 2 to climb up the base 12 smoothly and achieve communication with the recovery component 3 through the connection port 121, a lifting component 123 for pulling and lifting the robot 2 is provided on the base 12. The lifting component 123 includes a lifting track 1231 and a lifting member 1232. The lifting member 1232 can slide up and down along the lifting track 1231 under the drive of the lifting track 1231. The surface of the base 12 is provided with a groove (not numbered) for accommodating the lifting track 1231. The lifting member 1232 is connected to the lifting track 1231 through a rotating shaft so that the pitch angle of the lifting member 1232 is adjustable.

Furthermore, the edge of the robot 2 is also provided with a lifting handle 201 corresponding to the lifting member 1232; when the robot 2 needs to dock at the docking position, the robot 2 runs to the bottom edge of the base 12, and makes the lifting handle 201 located above the lifting member 1232, so that the lifting member 1232 extends into the inner side of the lifting handle 201; the lifting rail 1231 drives the lifting member 1232 to move on the base 12, and makes the placement angle of the lifting member 1232 rotate upward with the rotating shaft as the axis in the direction of the lifting handle 201, so as to be buckled on the lifting handle 201, and then drives the robot 2 to move on the base 12 until the robot 2 moves to the docking position, the lifting rail 1231 stops moving, and the robot 2 is connected with the recovery component 3 and/or the maintenance component to complete the recovery and cleaning of the dirt inside the robot 2 and/or the corresponding maintenance work. When the robot 2 needs to leave the base 12, the lifting member 1232 moves downward along the base 12 driven by the lifting rail 1231, and the robot 2 moves downward along the base 12 under the action of the internal drive motor or gravity. When the robot 2 moves to the bottom edge of the base 12, the lifting member 1232 continues to move a distance driven by the lifting rail 1231, so that the placement angle of the lifting member 1232 drops back, and the lifting member 1232 detaches from the lifting handle 201, thereby realizing the separation between the lifting component 123 and the robot 2.

It should be noted that, in the present embodiment, only the lifting component 123 including the lifting rail 1231 and the lifting member 1232 is taken as an example for illustration. In other embodiments of the present application, the lifting component 123 can also be configured as a conveyor belt or other structure for conveying objects on an inclined surface. That is, the setting structure of the lifting component 123 in the present embodiment is only exemplary and should not be limited to this.

In one embodiment of the utility model, the lifting component 123 also includes a covering member 1233, which is used to close or open the connection port 121 formed on the base 12. Such a configuration can, on the one hand, prevent the connection port 121 from being exposed to the air for a long time, causing the dirt contained in the recovery component 3 to escape into the environment again, causing secondary pollution of the working area; on the other hand, the connection port 121 can be shielded in real time to prevent the user from accidentally getting stuck in the connection port 121 or in the gap formed on the base 12, thereby effectively improving the safety of the base station 1.

In this embodiment, the covering member 1233 can move on the surface of the base 12 along with the lifting rail 1231. Further, a receiving groove for receiving the lifting cover plate 1233 is formed on the base 12 to receive the covering member 1233 moving along with the lifting rail 1231.

Please refer to Figures 9 and 10. In a preferred implementation of this embodiment, the lifting rails 1231 are arranged in pairs, and the covering member 1233 is formed between the two lifting rails 1231. The covering member 1233 is composed of a series of narrow cover strips. Furthermore, the long sides of two adjacent narrow cover strips are connected, and the covering member 1233 is formed with a lifting cross bar, and the lifting member 1232 is arranged on the lifting cross bar. In this way, when the robot 2 leaves the base station 1 and starts cleaning, the covering member 1233 The front end of 33 drops to the bottom of the base 12, and the surface of the base 12 is completely covered by the covering member 1233; when the robot 2 enters the base station 1, the lifting member 1232 is hung on the lifting handle 201, and the covering member 1233 rolls upward along the lifting track 1231, while driving the robot 2 to rise along the base 12; and in the present embodiment, the covering member 1233 is rolled and accommodated into a cylindrical shape and accommodated in a receiving groove formed on the base 12, so as to effectively reduce the projection area of the base station 1 on the horizontal plane.

In another implementation of the present embodiment, the receiving groove is a slide groove formed on the back side of the base station 1 and extending in the vertical direction (as shown in Figure 11), that is, in the present embodiment, the lifting rail 1231 can drive the covering member 1233 to slide along the surface of the base 12, and then control the connection port 121 to be exposed or covered, that is, in the present disclosed embodiment, the specific setting form and position of the receiving groove can be selected according to actual needs, and the setting form in the present disclosed embodiment is only exemplary and should not be limited to this.

In another preferred embodiment of the present application, the covering member 1233 is arranged on a cloth curtain on the lifting track 1231 (FIG. 12). Similarly, a lifting cross bar for connecting the lifting member 1232 is arranged at the bottom of the extension of the lifting track 1231. The cloth curtain is further fixed on the lifting cross bar so that the cloth curtain can be stretched or folded, thereby covering or opening the connection port 12 on the base. In this embodiment, a folding mark is preset on the cloth curtain. In this way, when the robot 2 leaves the base station 1 and starts cleaning, When the robot 2 enters the base station 1, the lifting member 1232 is hung on the lifting handle 201, and the robot 2 and the cloth curtain rise along the surface of the base 12 along the lifting track 1231 at the same time, and the cloth curtain is folded in an orderly manner during the process (Figure 13), so that the connection port 121 is exposed, and docking with the robot 2 is completed, and then subsequent operations are performed.

It should be noted that, in this specification, only the combination of the covering member 1233, the lifting rail 1231 and the lifting member 1232 is used as an example for explanation. In other embodiments of the present application, the covering member 1233 can also be separately provided with the lifting rail 1231 and the lifting member 1232. Furthermore, the covering member 1233 can also be provided in other forms, and it is only necessary to ensure that the setting of the covering member 1233 can close or open the connecting port 121 on the base 12.

The base station 1 also includes a take-out structure 13, which is used to realize the disassembly and installation of the recycling component 3, so as to facilitate the recycling component 3 to continue to dump the recycled and cleaned dirt. In this embodiment, the take-out structure 13 is a folding door formed on the base 12, and the connection port 121 and the positioning structure 122 are both arranged on the folding door 13, so that the relative position of the connection port 121 and the positioning structure 122 is stable, and the relative position offset between the connection port 121 and the positioning structure 122 caused by multiple openings of the folding door 13 is avoided, and the connection position between the robot 2 and the connection port 121 is avoided when the robot 1 is docked at the docking position. Furthermore, the folding door 13 is a folding structure that can be folded up and down in the vertical direction, so as to avoid the folding door 13 from interfering with other positions of the shell 11 during the folding process, thereby affecting the normal removal of the recycling component 3.

Of course, in another implementation of this embodiment, the taking-out structure 13 can also be arranged on the side wall of the housing 11, and the folding direction of the taking-out structure 13 can be either horizontal or vertical. That is, the setting position and setting form of the taking-out structure 13 in this embodiment can be selected according to actual needs, and the structures in the specification and drawings of this utility model are only exemplary and should not be limited thereto.

It should be noted that, in this embodiment, only the base 12 is formed in the shell 11 as an example for illustration. In other embodiments of the utility model, the base 12 can also be independently set as a whole and detachably connected to the shell 11 (as shown in Figure 14); a limiting slide groove for limiting the installation position of the base 12 is also formed in the shell 11. In this case, there is no need to set a removal structure 13. The cleaning and installation of the recovery component 3 accommodated under the base 12 can be completed by disassembling the base 12, thereby achieving the purpose of simplifying the structure of the base station 1.

Please refer to Figures 15 and 16. The robot 2 includes a main body 21, a moving component 22 for driving the main body 21 to move, a cleaning component 23 arranged at the bottom of the main body 21, a dust collecting motor and a dust collecting box 24 accommodated in the main body 21. The main body 21 is used to control the movement of the moving component 22, the cleaning component 23 and the dust collecting motor; the moving component 22 is arranged at the bottom of the main body 21, driving the cleaning component 23 connected to the main body 21 to move in the working area; the cleaning component 23 is used to clean the working area. Furthermore, a dust collecting port 211 connected to the dust collecting box 24 is arranged at the bottom of the main body 21. The dust collecting motor is connected to the dust collecting box 24, and the dust collecting box 24 provides a dust collecting airflow for the dust collecting port 211. The dust collecting motor cooperates with the cleaning component 23 to collect and temporarily store the dirt in the working area, so as to prevent the dirt from being left in place and causing re-contamination to the working position after cleaning.

As shown in Fig. 17, the cleaning assembly 23 includes a sweeping unit 231 disposed at the front side of the main body 21 in the running direction and a mopping unit 232 disposed at the rear side of the main body 21 in the running direction. The sweeping unit 231 is used to gather solid dirt such as dust and debris in the working area, so that the dust box 24 can collect the dirt through the dust collection port 211; the mopping unit 232 is used to wipe the working area after being swept by the sweeping unit 231, so as to further remove the dirt remaining in the working area.

In this embodiment, the sweeping unit 231 includes a roller brush component 2311 set in the dust collecting port 211 and a side brush component 2312 set at the edge of the main body 21, and along the running direction of the robot 2, the side brush component 2312 is located at the front side of the dust collecting port 211 and/or the roller brush component 2311. With such a configuration, the dirt in the working area can be gathered by the side brush component 2312, and the dirt can be further brushed (swept) to the dust collecting port 211 by the roller brush component 2311, and the dirt can be collected by the dust box 24 to clean the stubborn dirt on the ground.

Of course, in other embodiments of the present application, the cleaning component 23 may also be provided with only a sweeping unit 231. Further, the sweeping unit 231 may also be a sweeping component provided with only two side brush components 2312. The two side brush components 2312 are symmetrically arranged on the front side of the dust collecting port 211 to gather the dirt in the working area at the location of the dust collecting port 211, so as to facilitate the dust box 23 to collect the above dirt.

Referring to Figures 16 to 18, the dust box 24 is used to collect and temporarily store dirt, and includes an air outlet (not shown) connected to the dust collecting fan, an air inlet (not shown) connected to the dust collecting port 211, a dust outlet 241 connected to the recycling component 3, and a dust outlet component 242 for closing or opening the dust outlet 241. The air outlet and the air inlet are located on different side walls of the dust box 24, and the dust outlet 241 is arranged at the bottom or side of the dust box 24 and is staggered with the air outlet.

In this embodiment, the width of the dust outlet 241 is ≥35mm, and the length is ≥45mm. This configuration makes the dust outlet 241 have a larger size area, which is convenient for the recycling component 3 to recycle the dirt collected in the dust box 24. Furthermore, the surface of the base 12 is provided with a first sealing component 124, which is arranged around the connecting port 121. When the robot 2 runs to the docking position and is connected to the connecting port 121 through the dust outlet 241, the first sealing component 124 can seal the gap between the dust outlet 241 and the connecting port 121, on the one hand, preventing the dirt in the dust box 24 from escaping during the recycling and cleaning process; on the other hand, it can effectively prevent the power loss of the recycling component 3 caused by the existence of the gap, and ensure the recovery power of the recycling component 3.

The dust outlet component 242 includes a cover plate 2421 and a movable unit 2422 for controlling the cover plate 2421 to close or open the dust outlet 241; specifically, the movable unit 2422 has an open state and a closed state that can be switched. When the movable unit 2422 is in the open state, the cover plate 2411 opens the dust outlet 241; so that the dust box 24 is connected to the recycling component 3 through the dust outlet 241 and the connecting port 121 to complete the dumping of dirt; and when the movable unit 2422 is in the closed state, the cover plate 2411 closes the dust outlet 241 to prevent the dirt contained in the dust box 24 from leaking/falling out from the dust outlet 241, thereby facilitating the work and movement of the robot 2. The setting of the dust outlet component 242 allows the dust outlet port 241 of the present application to be opened actively, avoiding the power loss caused by using the recovery component 3 to provide power for opening the dust outlet port 241 and maintaining the dust outlet port 241 in an open state, effectively reducing the power loss of the recovery component 3, so that the cleaning system of the present application can still achieve rapid recovery and cleaning of dirt in the dust box 24 even if a smaller power recovery component 3 is used, thereby effectively avoiding the problem of high operating noise of the cleaning system caused by the use of a high-power recovery component 3.

The cover plate 2421 in this embodiment is rotatably connected to one side edge of the dust outlet 241 in the length direction through an elastic rotating shaft 2423, and makes the cover plate 2421 have a tendency to fold toward the direction of the connecting port 121; the movable unit 2422 is a rotating movable part arranged on one side edge in the width direction of the dust outlet 121; further, a guide member 125 corresponding to the movable unit 2422 is provided on the base 12, and the guide member 125 can control the movable unit 2422 to switch from a closed state to an open state to open the dust outlet 241, and then make the dust box 24 connected with the recovery component 3 through the dust outlet 241 and the connecting port 121.

Specifically, the guide member 125 is arranged at the edge of the connection port 121. When the robot 2 moves along the base 12 from the bottom edge of the base 12, the guide member 125 abuts against the inner edge of the rotating movable member 2422, so that the rotating movable member 2422 rotates from the closed state to the open state. At this time, the cover plate 2421 is folded toward the direction of the connection port 121 under the drive of the elastic rotating shaft 2423, and the cover plate 2421 abuts against the inner side of the connection port 121, so as to complete the alignment between the dust outlet 241 and the connection port 121 while opening the dust outlet 241. Then, the recycling component 3 completes the recycling of the dirt in the dust box 24; when the dirt recycling is completed, the robot 2 withdraws from the base 12, and the cover 2421 compresses the elastic shaft 2423 under the support of the edge of the connecting port 121 to close the dust outlet 241; further, the guide member 125 is separated from the rotating movable member 2422, and the rotating movable member 2422 returns from the open state to the closed state, and is re-clamped on the outer surface of the cover 2421 to lock the cover 2421 in the closed position, so that the dust outlet 241 is in a closed state.

Preferably, the rotating movable parts 2422 in this embodiment are arranged in pairs at both side edges of the dust outlet 121 in the width direction, and the guide members 125 are arranged in pairs at both side edges of the connecting port 121 and are arranged corresponding to the rotating movable parts 2422 .

Please refer to Figures 19 and 20. In another preferred embodiment of the present application, the elastic shaft 2423 includes a clamping piece 2424 arranged on both sides of the length direction of the cover plate 2421, and the movable unit 2422 is a locking pin assembly arranged on both sides of the length direction of the cover plate 2421. The locking pin assembly includes a locking pin arranged corresponding to the clamping piece 2424 and an elastic member for elastically fixing the locking pin. When the cover plate 2421 is in a closed state, the locking pin cooperates with the clamping piece 2424 to provide a closing force to the cover plate 2421 to close the dust outlet 241 to prevent the dirt contained in the dust outlet assembly 242 from leaking; and when the robot 2 enters the base station 1 to recycle the dirt, the recovery fan 32 in the base station 1 is started, and the negative pressure generated by the recovery fan 32 acts on the cover plate 2421, bringing The movable cover 2421 rotates, and then the clamping piece 2424 compresses the locking pin on the locking pin assembly during the rotation process, so that the clamping piece 2424 is disengaged from the locking pin; further, when the robot 2 moves downward along the surface of the base 12 and leaves the base station 1, the base 12 pushes the cover 2421 to rotate, so that the cover 2421 rotates toward the dust outlet 241, and the extended end of the clamping piece 2424 is re-engaged with the end of the locking pin, and then the dust outlet 241 is re-closed; preferably, the extended end of the clamping piece 2424 and the locking pin are both chamfered, so as to facilitate the clamping and separation of the clamping piece 2424 and the locking pin. With this arrangement, the cover 2421 can be clamped and separated from the locking pin even if it is rotated at a small angle under the action of negative pressure. Preferably, when the cover 2421 flips over at an angle greater than a preset angle, such as 9 degrees, under the action of negative pressure, the retaining member 2424 separates from the locking pin. At this time, the closing force of the cover 2421 drops to zero, so that the cover 2421 can be opened under the elastic force of the elastic rotating shaft 2423, thereby ensuring the opening angle of the dust outlet 241 of the dust box 24, thereby facilitating the rapid dust discharge of the dust box 24.

Please refer to Figures 21 to 23, the present application also provides another embodiment, the movable unit 2422 is a tension spring assembly arranged on both sides of the cover 2421 in the length direction. Specifically, the tension spring assembly is two tension spring components arranged in pairs, one end of the tension spring component is hooked on the shell of the dust box 24, and the other end is hooked on both sides of the cover 2421. When the cover 2421 is in a closed state, the tension spring provides a closing force to the cover 2421 under the action of its own tension to prevent leakage of dirt; when the robot 2 enters the base station 1, the recovery fan 32 in the base station 1 is started, and the negative pressure generated by the recovery fan 32 acts on the cover 2421, so that the cover 2421 rotates a certain angle. When the tension spring is stretched to the longest state, the negative pressure generated by the recovery fan 32 will drive the cover 2421 to continue to flip along the original direction, thereby changing the direction of the tension of the tension spring, and further converting the closing force of the cover 2421 that closes the dust outlet 121 into an opening force, pulling the cover 2421 open to the maximum flipping angle, thereby facilitating the rapid dust discharge of the dust box 24.

Please refer to Figures 24 and 25, which are schematic diagrams of the structure of the dust outlet component 242' in another preferred implementation manner of the present embodiment. In the present embodiment, the cover plate 2421' is connected to one side edge of the dust outlet 241 in the length direction through the flip shaft 2423', and the movable unit 2422' is a driving motor arranged on one side edge of the dust outlet 241 in the width direction; further, the driving motor 2422' is arranged on the dust box 24, and the driving shaft of the driving motor 2422' is drivingly connected to the flip shaft 2423'. Similarly, the driving motor 2422' can switch between an open state and a closed state, and then drive the cover plate 2421' to open or close the dust outlet 241 through the flip shaft 2423'.

Furthermore, in other embodiments of the present application, the cover 2421 can also be rotatably connected to one side edge of the dust outlet 241 in the length direction through a rotating shaft (not shown), and the movable unit 2422 is a locking member (not shown) arranged on the side of the cover 2421 away from the rotating shaft, and the locking member can switch between a closed state and an open state under the action of an external force. Specifically, when the robot 2 runs along the base 12 from the edge of the base 12, the locking member is converted from the closed state to an open state under the action of the recycling airflow provided by the recycling component 3 or under the action of an external force, and the cover 2421 rotates around the rotating shaft under the action of gravity to open the dust outlet 2421, so as to facilitate the recycling component 3 to complete the recycling of dirt in the dust box 24; when the dirt recycling is completed, the robot 2 withdraws from the base 12, and the cover 2421 rotates around the rotating shaft toward the direction of the dust box 24 under the support of the edge of the connecting port 121, and the locking member returns from the open state to the closed state, so that the cover 2421 remains in the closed position to close the dust outlet 241.

Preferably, the locking piece in this embodiment is a magnetic piece arranged on the side of the cover plate 2421 away from the rotating shaft, and a metal piece is provided at the edge of the dust outlet 241 corresponding to the magnetic piece, so that the magnetic piece can be attracted to the metal piece, and then the cover plate 2421 can close the dust outlet 241; further, when the robot 2 is docked on the base 12, and the recovery suction force of the recovery airflow provided by the recovery component 3 is greater than the magnetic force between the magnetic piece and the metal piece, the magnetic piece is separated from the metal piece, and the cover plate 2421 rotates around the rotating shaft under the action of gravity to open the dust outlet 2421; when the dirt recovery is completed, the robot 2 withdraws from the base 12, the recovery component 3 stops providing the recovery suction force and the cover plate 2421 rotates around the rotating shaft toward the direction of the dust box 24 under the support of the edge of the connecting port 121, and the magnetic piece is re-attracted to the metal piece, so that the cover plate 2421 remains in the closed position, so as to re-close the dust outlet 241 through the cover plate 2421.

It should be noted that the setting structure of the dust outlet assembly 242, 242' provided in the specification and the drawings of the specification in the present application is only exemplary. In other embodiments of the present application, the dust outlet assembly 242 can also be set to other forms, and it is only necessary to ensure that the dust outlet assembly 242 has a cover plate 2421 and a movable unit 2422 that controls the cover plate 2421 to actively close or open the dust outlet port 241; further, the specification and the drawings of the specification in the present application only take the cover plate 2421 as an integrally arranged plate-like member, and the cover plate 2421 is movably connected to one side edge of the length direction of the dust outlet 241 as an example for illustration. In other embodiments of the utility model, the cover plate 2421 can also be set on one side edge of the width direction of the dust outlet 241, or be separately set on the edge of the length/width direction of the dust outlet 241, and it is only necessary to ensure that the cover plate 2421 can actively open/close the dust outlet 241 under the control of the movable unit 2422.

In another preferred embodiment of the present application, the dust outlet assembly 242 may also include only the cover plate 2421 and an elastic shaft 2423 for rotatably connecting the cover plate 2421 to one side edge in the length direction of the dust outlet 241. Referring to FIGS. 26 to 28 , the elastic shaft 2423 also includes locking cams arranged on both sides in the length direction of the cover plate 2421 and positioning leaf springs symmetrically arranged on both sides of the cover plate 2421. Specifically, when the elastic shaft 2423 is in a closed state, the leaf spring cooperates with its locking cam to provide a closing force to the elastic shaft 2423 to prevent leakage of dirt; when the robot 2 enters the base station 1, the recovery fan 32 in the base station 1 is started, and the recovery fan 32 generates a negative pressure acting on the cover plate 2421 to drive the cover plate 2421 to flip over a flip angle in the extension direction of the elastic shaft 2423, thereby causing the locking cam and the leaf spring to move relative to each other and pass over the protruding position of the locking cam. At this time, the elastic shaft 2423 drives the cover plate 2421 to close the dust outlet 241 The force drops to negative, and then the elastic force of the elastic shaft 2423 is converted into a door-opening force, so that the cover 2421 is fully opened under the elastic force of the elastic shaft 2423; further, when the robot 2 moves downward along the surface of the base 12 and leaves the base station 1, the base 12 pushes the cover 2421 to rotate, so that the cover 2421 rotates toward the dust outlet 241, and the extended end of the leaf spring re-crosses the protruding position of the locking cam, and then re-completes the closure of the dust outlet 241. Such a setting can effectively reduce the setting volume of the dust outlet component 242, and then increase the storage volume of the dust box 24.

Please refer to Figures 29 and 30 and in combination with Figure 6, the recycling component 3 is accommodated in the base station 1 for recycling the dirt collected in the dust box 24. In the present utility model, the recycling component 3 includes a recycling box 31 detachably arranged in the accommodation space below the base 12 and a recycling fan 32 connected to the recycling box 31; wherein the recycling box 31 is connected to the dust box 24 through the connection port 121, and the recycling fan 32 provides a recycling airflow from the dust box 24 to the recycling box 31, so as to recycle the dirt collected in the dust box 24 into the recycling box 31 for centralized processing.

The recycling box 31 is provided with a recycling port 311 corresponding to the dust outlet 241 of the dust collecting box 24 and an air supply port 24 connected to the recycling fan 32. The recycling port 311 and the air supply port 312 are staggered, and a HEPA filter assembly (not numbered) is also provided at the air supply port 312 to prevent the dirt collected in the recycling box 31 from entering the recycling fan 32 along the air supply port 312, causing the suction force of the recycling airflow to decrease and affecting the recycling efficiency of the recycling assembly 3 to collect dirt.

Specifically, the recycling box 31 is directly/indirectly connected to the dust box 24 through the recycling port 311, the connecting port 121 and the dust outlet 241. Please refer to FIG30 , when the recycling box 31 and the dust box 24 are directly connected, the wall of the recycling box 31 provided with the recycling port 311 abuts against the inner side of the base 12, so that the recycling port 311 is connected with the connecting port 121, and further, a second sealing component 126 located on the inner surface of the base 12 is provided between the recycling port 311 and the connecting port 121, and the second sealing component 126 is arranged around the connecting port 121 to achieve a sealed connection between the recycling port 311 and the connecting port 121; to prevent the recycling airflow provided by the recycling fan 32 from leaking from the connection gap between the recycling port 311 and the connecting port 121, effectively improve the sealing performance when the dust box 24 is connected to the recycling box 31, and then achieve the effect of improving the suction force of the recycling airflow and achieving the effect of efficient collection of dirt.

Please refer to Figure 31, the cleaning system also includes a recovery duct 4 formed between the dust box 24 and the recovery box 31. Specifically, when the robot 2 is docked on the base 12, the recovery box 31 and the dust box 24 are connected through the recovery duct 4, and the recovery airflow drives the dirt in the dust box 24 to move from the dust outlet 241 through the recovery duct 4 to the recovery port 311 to reach the recovery box 31. The moving path length of the dirt in the recovery duct 4 is defined as d, then 0＜d≤70mm.

Such a configuration can, on the one hand, reduce the setting length of the recovery air duct 4, facilitating the miniaturization of the cleaning system, and on the other hand, effectively reduce the probability of collision between the dirt and the inner wall of the recovery air duct 4 when the recovery fan 32 is recycling the dirt in the dust collection box 24, so as to reduce the recovery noise when the recovery component 3 recycles the dirt, and at the same time reduce the power loss of the recovery fan 32, so that the recovery of the dirt can be completed using a smaller power recovery fan 32, so as to further reduce the recovery noise when the recovery component 3 recycles the dirt.

Specifically, the recovery air duct 4 is formed on the base 12 and extends from the edge of the connecting port 121 toward the direction of the dust box 24 or the recovery box 31, so as to connect the recovery box 31 and the dust box 24 through the connecting port 121 and the end portion extending from the recovery air duct 4, respectively; further, a side edge of the connecting port 121 away from the recovery air duct 4 and the end portion extending from the recovery air duct 4 are respectively provided with sealing components (not shown) to prevent insufficient recovery suction of the recovery component 3 caused by leakage of the recovery airflow.

Preferably, the recovery air duct 4 is a linear recovery air duct arranged in a linear shape (as shown in FIG. 32 ); of course, in other embodiments of the present application, the recovery air duct 4 may also be arranged in a bent shape, and the bend of the recovery air duct 4 does not exceed one. Such an arrangement, on the one hand, can reduce the power loss caused by the collision between the recovery airflow and the recovery air duct 4, so that the recovery of dirt can be completed using a smaller power recovery fan 32; on the other hand, it reduces the noise generated by the collision between the dirt and the inner wall of the recovery pipe 4, and further reduces the noise during the operation of the cleaning system, so that when the recovery component 3 performs the recovery work, the noise of the cleaning system operation is <82dB (A), which effectively improves the practicality and user-friendliness of the cleaning system.

Please refer to Figure 33. In another embodiment of the present disclosure, the recovery duct 4 is an arc-shaped duct with a certain curvature. In order to avoid a large number of collisions between the wall of the recovery duct 4 and the dirt when the recovery airflow drives the dirt to move in the recovery duct 4, thereby causing power loss of the recovery fan 32; the recovery duct 4 in this embodiment has a large bending angle. Specifically, as shown in Figure 34, along the contour center line S extending from the recovery duct 4, the angle α formed by the tangents of any two points on the center line S is an obtuse angle; similarly, the moving path length of the dirt in the arc-shaped recovery duct 4 is d, then 0＜d≤70mm.

It should be noted that the recovery air duct 4 described in the embodiment of the present invention is straight or has a certain curvature, which specifically means that the contour center line S of the recovery air duct 4 is straight or has a certain curvature, as shown in Figures 35 to 37, and whether there are bends or deformations on the wall surface of the recovery air duct 4 itself has no effect on the straightness or curvature of the recovery air duct 4 of the present invention, that is, the material, material structure, etc. used to make the recovery air duct 4 have no actual effect on the extension form of the recovery air duct 4.

The recovery fan 32 provides the recovery box 31 with a recovery airflow for recovering dirt through the air supply port 312. In this embodiment, the recovery fan 32 is arranged in the receiving space and is located between the recovery box 31 and the base 12; such an arrangement can, on the one hand, effectively improve the utilization rate of the receiving space in the vertical direction, and conveniently reduce the floor space occupied by the cleaning system in the horizontal direction; on the other hand, it can facilitate the arrangement of the recovery box 31, facilitate the large-volume setting of the recovery box 31, and enhance the working life of the cleaning system.

In order to further improve the dust collection effect of the base station 1 in the present application, an airflow optimization structure is also provided in the base station 1. In fact, due to the volume of the recycling box 31, the recycling port 311 and the air supply port 312 provided on the recycling box 31 are usually close to each other. Therefore, when the recycling fan 32 provides a recycling airflow to the recycling port 311 through the air supply port 312, the recycling airflow will drive the dirt to accumulate directly near the air supply port 312, thereby causing the problem of excessive accumulation of local dirt in the recycling box 31, so that the volume of the recycling box 31 cannot be fully utilized.

Based on this, the utility model has further improved the structure of the recycling box 31, please refer to Figure 38, an airflow optimization structure 33 is set between the recycling port 311 and the air supply port 312, and when the recycled air flows into the recycling box 31, it will continue to flow along the airflow optimization structure 33 and finally flow to the air supply port 312; at this time, the dirt entrained in the recycled airflow will traverse the space inside the recycling box 31, and then the dirt will be evenly distributed inside the recycling box 31, making full use of the internal space of the recycling box 31 to accommodate more dirt.

Specifically, the airflow optimization structure 33 can be an airflow optimization baffle arranged in the recovery box 31 and corresponding to the recovery port 311. The recovered airflow containing dirt acts on the airflow optimization baffle and continues to flow along the extension direction of the airflow optimization baffle, so that the dirt is evenly distributed inside the recovery box 31; optionally, the airflow optimization baffle is arranged in a straight line or a bend.

Of course, in other embodiments of the utility model, the airflow optimization structure 33 can also be an airflow optimization pipeline arranged at the edge of the recovery port 311 and connected to the recovery air duct, that is, the airflow optimization pipeline will be diverted by the recovery airflow, and further transport the dirt entrained in the recovery airflow to various positions of the recovery box 31 to fully utilize the recovery box 31.

Furthermore, the power of the recovery fan 32 in the present application is less than 550W. Such a setting can effectively reduce the noise when the recovery component 3 recovers the dirt in the dust box 24, and realize a low-noise setting of the cleaning system. In fact, the setting length and setting form of the recovery air duct 4 used to connect the recovery box 31 and the dust box 24 in the cleaning system of the utility model can effectively reduce the wind loss when the recovery fan 4 is working, so that even if the recovery fan 32 with a power of less than 550W is used, the recovery efficiency of the dirt in the dust box 24 of the robot 2 by the base station 1 can be guaranteed.

Further, refer to Table 1 below, which is a table showing the relationship between the power of the recovery fan 32 and the operating noise of the cleaning system in the present invention.

Table 2 shows the relationship between the length of the recycling duct, the dust box recycling and cleaning efficiency, and the risk of dust duct blockage.

Table 1 Relationship between the power of the recovery fan and the operating noise of the cleaning system

Table 2 Relationship between the length of the recycling duct, the dust box recycling and cleaning efficiency, and the risk of dust duct blockage

It can be seen from Tables 1 and 2 above that the cleaning system of the utility model uses a recovery fan 32 with a power of less than 550W, so that the operating noise of the cleaning system is less than 80dB (A); preferably, the operating noise of the cleaning system is between 40 and 60dB (A). At the same time, by setting the length of the recovery air duct 4 to match the power of the recovery fan 32, the dirt recovery efficiency of the dust box 24 can reach more than 85%, while ensuring the dirt recovery efficiency, the operating noise of the cleaning system is effectively reduced.

In fact, the noise during the operation of the cleaning system is mainly related to the power of the recovery fan 32, that is, the greater the operating power of the recovery fan 32, the higher the operating noise of the cleaning system; in the prior art, since the positions of the robot 2 and the base station 1 are not arranged reasonably when the robot 2 is docked in the base station 1, there are many bending positions in the recovery air duct 4 connecting the recovery fan 32 and the dust box 24 in the robot 2, which causes a large amount of loss of the recovery airflow provided by the recovery fan 32 in the recovery air duct 4; and in order to ensure the dirt recovery efficiency of the cleaning system (the dirt recovery efficiency is the recovery and cleaning efficiency of the dust box 24 by the recovery fan 32, and the emptying efficiency of the dust box 24), a larger power recovery fan 32 is usually used to clean the dirt in the dust box 24. The dirt in the dust box 24 is recovered. Although physical noise reduction can be used, such as setting a noise reduction interlayer (noise reduction cotton) in the base station 1 to filter out the operating noise of the cleaning system, when the power of the recovery fan 32 is large, the effect of noise filtering is not obvious, resulting in the cleaning system in the prior art either having low operating noise and low recovery efficiency; or having high operating noise and low recovery efficiency; in the utility model, the dust box 24 in the robot 2 is connected with the recovery box 31 in the base station 1 through a recovery duct 4 with a shorter length and fewer bends, and the setting length and setting form of the recovery duct 4 are adjusted, so that even if a smaller power recovery fan 32 is used, efficient recovery and cleaning of the dirt in the dust box 24 can still be achieved.

Furthermore, by arranging that the dust box 24 and the recovery box 31 are arranged opposite each other when the robot 2 is docked on the base 12, the large-size setting of the dust outlet 241 of the dust box 24 is facilitated, thereby further improving the dirt recovery efficiency of the cleaning system; at the same time, the short setting of the recovery air duct 4 and the setting of the arrangement form when the robot 2 is docked on the base 12 realize the small-size design of the cleaning system, thereby effectively improving the use performance and user-friendliness of the cleaning system.

When using the cleaning system in this embodiment, when the dust box 24 in the robot 2 is full and needs to return to the base station 1 to clean the dirt, the robot 2 can search for the positioning signal sent by the positioning structure, and then climb along the base 12 to the docking position with the assistance of the lifting component 123.

Furthermore, the dust outlet assembly 242 actively opens the dust outlet 241 so that the dust box 24 is connected to the recovery box 31 through the connection port 121 and/or the recovery air duct 4 provided on the base 12, and the recovery fan 32 provides a recovery airflow, so that the dirt in the dust box 24 enters the recovery box 31 along with the recovery airflow. In this embodiment, since the dust box 24 is located above the recovery box 31, when the dust box 24 is opened to clean the dirt, the dirt in the dust box 24 is also affected by gravity, and then the dirt can be cleaned more conveniently and quickly, and the recovery and cleaning of the dirt can be completed without using a high-power recovery fan 32, and then the working noise of the cleaning system when the dirt is recovered and cleaned is effectively reduced.

It should be noted that, in this embodiment, only the recycling component 3 is arranged below the base 12 as an example for illustration. In another implementation of this embodiment, the recycling box 31 can also be directly arranged on the base 12 (as shown in Figure 39). At this time, the base 12 also includes a limiting portion (unnumbered) arranged perpendicular to its extension plane, and the recycling box 31 is detachably arranged between the limiting portion and the shell 11, and the connecting port 121 is arranged on the limiting portion. Furthermore, the dust box 24 is arranged close to the edge of the robot 2, so that the dust box 24 and the recycling box 31 are connected through the dust outlet 241 arranged on the outer peripheral edge of the robot 2 through the connecting port 121, thereby realizing the recovery of dirt.

In addition to the structures illustrated in the above specification, the cleaning system also includes a charging component 5 and/or a water-adding component 6 disposed in the base station 1. The charging component 5 includes a charging interface connected to the robot 2 for charging; the water-adding component 6 includes a water-adding interface connected to the robot 2 for water-adding. The charging interface and the water-adding interface are located at the top end extending from the base 12. Preferably, the mounting planes of the charging interface and the water-adding interface are disposed perpendicular to the base 12. With such an arrangement, when the robot 2 moves along the base 12 and stops at the stop position, the charging socket and the water-adding socket disposed on the outer peripheral wall of the main body 21 of the robot 2 can be used to complete the replenishment of electric energy and/or water, making the use of the cleaning system of the present application more convenient and quick. Since the charging component 5 and the water-adding component 6 are both mature accessories, they will not be described in detail in this specification.

Please refer to Figures 40 and 41 in combination with Figures 1 and 2, which show a cleaning system in another preferred embodiment of the present invention. In this embodiment, the cleaning system has a structure substantially the same as that of the aforementioned embodiment, the only difference being that the base 12 and the recovery component 3 are located in different positions. Therefore, the following description will only describe the differences between the two embodiments, and similar/identical parts will not be repeated here.

In this embodiment, the base 12 has a parking portion 127 extending in a horizontal direction and an extension portion 128 extending obliquely from the edge of the parking portion 127. The recovery component 3 is accommodated below the parking portion 127. Furthermore, a connection port 121 is provided on the parking portion 127. In this configuration, when the robot 2 needs to return to the base station 1 to continue cleaning the dirt, the robot 2 travels along the extension portion 128 to the parking portion 127, and communicates with the recovery component 3 located below the parking portion 122 through the connection port 121 provided on the parking portion 127, so as to complete the recovery of the collected dirt under the dual action of the recovery component 3 and gravity. Based on this embodiment, a smaller power recovery fan 32 can be used to recover and clean the dirt in the dust box 24, so as to further reduce the sound power value of the noise during the operation of the cleaning system while ensuring the recovery efficiency of the cleaning system.

In this embodiment, the extension portion 128 is inclined at a small angle so that the robot 2 can climb along the extension portion 128 to the extension portion 128 without the need for external force, such as without the need for a lifting component 124, to achieve docking with the recovery component 3.

Furthermore, in other implementations of the present embodiment, the recovery component 3 can also be arranged on the surface of the parking portion 127 away from the extension portion 128, and the extension portion 128 and the parking portion 122 are roughly located in the same plane (as shown in Figure 41), and the connecting port 121 is arranged on the limiting portion of the base 12 vertically arranged on the parking portion 122; the dust box 24 is arranged close to the edge of the robot 2, and the dust outlet 241 is arranged on the outer peripheral wall of the main body 21; to further facilitate the robot 2 to drive along the extension portion 128 to the parking portion 127, the dust box 24 and the recovery box 31 are connected to the recovery box 31 through the dust outlet 241 arranged on the outer peripheral wall of the main body 21 via the connecting port 121 and/or the recovery air duct 4 to realize the recovery and cleaning of dirt.

To sum up, the cleaning system of the utility model sets the relative position of the dust box 24 and the recovery box 31 so that the recovery fan 32 can provide a recovery airflow for recovering and cleaning the dirt in the dust box 24 without passing through the recovery air duct 4 or only through a shorter recovery air duct 4. On the one hand, it avoids the setting of a bent air duct between the recovery box 31 and the dust box 24. On the other hand, while the recovery fan 32 provides recovery power, it avoids the power loss of the recovery fan 32. A recovery fan 32 with a power lower than 550W can be used instead of a high-power recovery fan 32, which can not only ensure the cleaning efficiency of the cleaning system, but also effectively reduce the operating noise of the base station 1 during dirt recovery and cleaning, so that the noise rise power during the operation of the cleaning system can be reduced to below 82dB.

Furthermore, by setting the setting form of the base 12 for carrying the robot 2 in the base station 1, when the robot 2 is docked on the base 12, the projections of the dust box 24 and the recovery box 31 on the horizontal plane at least partially overlap, and while using the bent air ducts of the dust box 24 and the recovery box 31, the large-size design of the dust removal port 241 at the bottom of the dust box 24 and the recovery air duct 4 is convenient, thereby realizing the rapid recovery of dirt in the dust box 24; at the same time, by setting the base 12 to extend obliquely, the floor space occupied by the cleaning system in the horizontal direction can be effectively reduced, thereby facilitating the miniaturization design of the cleaning system.

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