Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning base station and cleaning equipment. Background Technology

[0002] In recent years, more automated cleaning equipment such as robotic vacuum cleaners and floor scrubbers have entered the lives of more and more people. These cleaning devices can significantly reduce the labor intensity of humans and improve people's lives. Cleaning equipment such as robotic vacuum cleaners and floor scrubbers typically include a cleaning base station and a cleaning device. The cleaning device can move autonomously or under human operation within a room, cleaning the floor in the process. After completing its cleaning task, the cleaning device can return to the cleaning base station to clean and dry the mop, preventing it from becoming moldy or smelly.

[0003] During the cleaning process of the cleaning device's mop, the wastewater generated during cleaning either falls into the wastewater tray or is pumped into the cleaning base station's wastewater tank via a suction pipe. However, if the mop has debris attached to it during cleaning, this debris can clog the suction pipe as it is being pumped into the wastewater tank, causing wastewater to accumulate in the wastewater tray and eventually overflow. Utility Model Content

[0004] Therefore, it is necessary to provide a clean base station and cleaning equipment to address the problem of sewage overflowing from the sewage pan.

[0005] A clean base station, comprising:

[0006] The base station body has a water receiving cavity inside and a sewage suction port communicating with the water receiving cavity. A connecting hole is formed on the surface of the base station body, and the connecting hole is connected to the water receiving cavity. When the cleaning device is cleaning the base station, the sewage generated by the cleaning component of the cleaning device can fall into the water receiving cavity through the connecting hole.

[0007] A detection component is installed on the main body of the base station, and when the water level in the water receiving chamber is greater than or equal to a preset threshold, the detection component issues an alarm signal.

[0008] In one embodiment, the base station body includes a main structure and a cover plate. The main structure is provided with the water receiving cavity, the cover plate is provided with the communicating hole, and the cover plate is detachably provided on the main structure.

[0009] When the cover plate separates from the main structure, the detection component issues an alarm signal.

[0010] In one embodiment, the detection component includes a first sensor and a second sensor. The first sensor is disposed on the main structure, and the second sensor is movably disposed on the cover plate on the side facing the water receiving cavity, and can move away from the first sensor as the water level rises.

[0011] Specifically, when the distance between the second sensor and the first sensor is greater than or equal to the preset threshold, the second sensor emits the alarm signal.

[0012] In one embodiment, the second sensing element is a magnet, and the first sensing element is a Hall effect detection PCB board. The Hall effect detection PCB board is capable of detecting the magnetic field of the magnet, and when the Hall effect detection PCB board fails to detect the magnetic field of the magnet, the Hall effect detection PCB board issues the alarm signal.

[0013] In one embodiment, the detection component further includes a floating element that is hinged to the cover plate about a hinge axis, and a second sensing element is provided on one end of the floating element in its longitudinal direction, the longitudinal direction of the floating element intersecting the direction of the hinge axis.

[0014] In one embodiment, the floating member includes a first end and a second end opposite to each other in its longitudinal direction, the hinge axis is located between the first end and the second end, and the second sensing element is disposed on the first end;

[0015] The cover plate is also provided with a first limiting rib. During the movement of the first end away from the cover plate, the second end can abut against the first limiting rib.

[0016] In one embodiment, the cover plate has two supports protruding from the surface facing the water receiving cavity, and each support has a hinge hole extending along the hinge axis.

[0017] The floating member has hinge shafts on both sides opposite to each other in the direction of the hinge axis, and the two hinge shafts are respectively located in the two hinge holes.

[0018] In one embodiment, at least one end of the hinge shaft away from the floating member has a chamfered bevel.

[0019] In one embodiment, the cover plate is further provided with a second limiting rib, which includes two ribs. The two ribs are spaced apart along the hinge axis, and the floating member passes through the two ribs.

[0020] A cleaning device includes a cleaning apparatus and a cleaning base station as described in any of the preceding claims.

[0021] When the sewage inlet of the aforementioned cleaning base station becomes clogged, a detection component installed on the main body of the base station can issue an alarm signal when the water level in the water receiving chamber reaches a certain height. This alarm signal stops the cleaning device from continuing to clean, or reminds the user to clear the blockage, thereby reducing the problem of sewage overflow from the water receiving chamber and improving the user experience.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] See Figures 1 to 3 This application provides a cleaning device, including a cleaning unit and a cleaning base station. The cleaning unit is used to perform cleaning tasks required by the user, such as sweeping or mopping the floor. The cleaning unit can be a robot vacuum cleaner or a floor scrubber. Specifically, the cleaning unit includes a cleaning component mounted on the cleaning body. The cleaning unit can carry the cleaning component and move it on the ground to perform sweeping or mopping actions on the floor.

[0045] The cleaning components can be mops, roller brushes, or other parts used for cleaning floors. The cleaning equipment also has a cleaning function to clean these components, ensuring effective cleaning each time the device performs its cleaning function. Specifically, when the cleaning device is located at a cleaning base station, the cleaning body or base station can spray cleaning fluid onto the cleaning components. After cleaning the floor for a period of time, the cleaning fluid cleans the components, removing stains and allowing them to continue cleaning the floor.

[0046] Among them, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The cleaning base station includes a base station body 10 and a detection component 20. The base station body 10 has a water receiving chamber 11 and a sewage suction port 12 connected to the water receiving chamber 11. A connecting hole 13 is formed on the surface of the base station body 10, and the connecting hole 13 is connected to the water receiving chamber 11. When the cleaning device is located at the cleaning base station, the cleaning component of the cleaning device can be positioned above the connecting hole, so that the wastewater generated by the cleaning component of the cleaning device can fall into the water receiving chamber 11 through the connecting hole 13.

[0047] The sewage inlet 12 inside the water receiving chamber 11 can be connected to the sewage tank inside the cleaning base station. By using a vacuum or a water pump, the sewage inlet 12 can be pumped from the water receiving chamber 11 into the sewage tank for unified disposal by the user. However, if the sewage inlet 12 is blocked by impurities in the sewage, it will be unable to properly pump sewage from the sewage tank, and the sewage will accumulate in the water receiving chamber 11 until it overflows from the connection point, causing sewage pollution to the surrounding environment and affecting the user experience.

[0048] To this end, the detection component 20 is installed on the main body 10 of the base station. The detection component 20 can detect the water level of the sewage in the water receiving chamber 11, and when the water level of the sewage in the water receiving chamber 11 is greater than or equal to a preset threshold, the detection component 20 issues an alarm signal. The alarm signal can be transmitted to the control center of the cleaning equipment or cleaning device. After receiving the alarm signal, the control center will stop the cleaning operation of the cleaning device, thereby preventing the water level in the water receiving chamber 11 from continuing to rise and causing sewage overflow. At the same time, after receiving the alarm signal, the control center can also simultaneously issue an audible and visual signal to remind the user that the sewage suction pipe 42 is blocked and to clean the sewage suction pipe 42 in time.

[0049] When the sewage inlet 12 of the aforementioned cleaning base station becomes clogged, the detection component 20 installed on the base station body 10 can issue an alarm signal when the water level in the water receiving chamber 11 reaches a certain height. This alarm signal stops the cleaning device from continuing to clean or reminds the user to clear the blockage, thereby reducing the problem of sewage overflow in the water receiving chamber 11 and improving the user experience.

[0050] In some embodiments of this application, the base station body 10 includes a main structure 30 and a cover plate 31. The main structure 30 is provided with a water receiving cavity 11, and the top of the water receiving cavity 11 is provided with an opening. The cover plate 31 is provided with a connection hole, and the cover plate 31 is detachably disposed on the main structure 30. When the cover plate 31 is disposed on the main structure 30, the cover plate 31 closes the opening at the top of the water receiving cavity 11.

[0051] Thus, after the cleaning equipment has been used for a period of time, the user can remove the cover plate 31 from the main structure 30, allowing the user to clean the cover plate 31 and the inside of the water receiving chamber 11, thereby reducing the problem of odors appearing in the water receiving chamber 11 and the cover plate 31 if they are not cleaned for a long time. However, in actual use, after cleaning the cover plate 31, the user may forget to install the cover plate 31 and start the cleaning equipment directly, which will cause the cleaning equipment to malfunction.

[0052] Therefore, when the cover plate 31 separates from the main structure 30, the detection component 20 can issue an alarm signal. After receiving the alarm signal, the control center of the cleaning equipment will issue audible and visual signals to remind the user that the cover plate 31 has been missing. At the same time, even if the user starts the cleaning equipment, the cleaning equipment will not start the cleaning operation because it continues to receive alarm signals, thus avoiding damage to the cleaning device or cleaning base station.

[0053] For example, the detection component 20 can not only alarm when the water level in the water receiving chamber 11 is too high, but also alarm when the cover plate 31 is removed from the main structure 30. That is, the detection component 20 can also be used to detect whether the cover plate 31 is installed in place. The detection component 20 has multiple functions and has the effect of being a multi-purpose device.

[0054] In some embodiments, the detection component 20 includes a first sensor and a second sensor 21. The first sensor is disposed on the main structure 30, and the second sensor 21 is movably disposed on the side of the cover plate 31 facing the water receiving cavity 11, and can move away from the first sensor as the water level rises. Specifically, when the water level in the water receiving cavity 11 rises to a certain height, the gradually rising sewage will push the second sensor 21 to rise together, thereby enabling the second sensor 21 to move away from the first sensor.

[0055] Specifically, when the distance between the second sensor 21 and the first sensor is greater than or equal to a preset threshold, the second sensor 21 issues an alarm signal. There are two scenarios where the distance between the second sensor 21 and the first sensor increases: either the water level in the water receiving chamber 11 rises, or the cover plate 31 is removed from the main structure 30. Regardless of the scenario, as long as the second sensor 21 detects an increase in the distance between itself and the first sensor, it will issue an alarm signal, thus providing alarms for both situations: the water level in the water receiving chamber 11 is too high, and the cover plate 31 is not installed.

[0056] In some specific embodiments, the second sensing element 21 is a magnet, and the first sensing element is a Hall effect detection PCB board. The magnet can generate a magnetic field within a certain range, and the Hall effect detection PCB board can detect the magnetic field generated by the magnet based on the way that the current will deflect in the magnetic field.

[0057] When the Hall effect sensor PCB can detect the magnetic field of the magnet, it means that the magnet is close enough to the Hall effect sensor PCB. At this time, the cover plate 31 is normally installed on the main structure 30, and the water level in the water inlet chamber 11 is normal. When the Hall effect sensor PCB fails to detect the magnetic field of the magnet, it means that the magnet is far enough away from the Hall effect sensor PCB. In this case, the cover plate 31 is removed from the main structure 30, or the water level in the water inlet chamber 11 rises to a higher position. In both cases, an alarm signal needs to be issued.

[0058] It should be noted that in some other embodiments, the first sensor can also be an ultrasonic rangefinder, which emits ultrasonic waves toward the second sensor 21 and measures the reflected signal of the sound waves to obtain the distance between the second sensor 21 and the first sensor. In still other embodiments, the first sensor can also be a laser rangefinder, which emits a laser toward the second sensor 21 and calculates the time difference between the laser emission and reflection to obtain the distance between the second sensor 21 and the first sensor.

[0059] Specifically, in some embodiments, see [link to relevant documentation]. Figure 7 and Figure 8 In order for the magnet to move away from the Hall effect detection PCB board as the water level in the water receiving chamber 11 rises, the detection assembly 20 also includes a floating element 22. The floating element 22 can float on the water surface and descend as the water level rises. One end of the floating element 22 is hinged to the cover plate 31 around a hinge axis 25. A second sensing element 21 is provided at one end of the floating element 22 in its longitudinal direction, and the longitudinal direction of the floating element 22 intersects the direction of the hinge axis 25.

[0060] Thus, when the water level of the sewage in the water receiving chamber 11 rises or falls, the sewage will cause the end of the floating member 22 equipped with the second sensor 21 to rotate around the hinge axis 25, and cause the second sensor 21 to move closer to or further away from the first sensor, until the water level in the water receiving chamber 11 rises to a dangerous level, and the distance between the first sensor and the second sensor 21 is far enough, so that the first sensor will issue an alarm signal.

[0061] It should be noted that when the first sensing element is an ultrasonic rangefinder or a laser rangefinder, the floating element 22 may not be provided. The second sensing element 21 can be made of a material that can float on the water surface, such as foam, so that the second sensing element 21 can float directly on the water surface of the water receiving cavity 11 and move closer to or further away from the first sensing element as the water level changes.

[0062] Specifically, in some embodiments, see [link to relevant documentation]. Figure 9 and Figure 10 The floating member 22 includes a first end 23 and a second end 24 arranged opposite to each other in its longitudinal direction. The hinge axis 25 is located between the first end 23 and the second end 24. That is, the part where the floating member 22 and the cover plate 31 are hinged to each other is in the middle of the floating member 22, so that when the floating member 22 rotates around the hinge, both the first end 23 and the second end 24 of the floating member 22 will rotate around the hinge axis 25.

[0063] The cover plate 31 is provided with a first limiting rib 32. When the first end 23 moves away from the cover plate 31, the second end 24 will gradually approach the second cover plate 31 and the second end 24 can abut against the first limiting rib, thereby preventing the floating part 22 from continuing to rotate through the first limiting rib.

[0064] In actual use, because the first end 23 is equipped with the second sensor 21, the weight of the floating part 22 at the first end 23 is greater than that at the second end 24. When the user removes the cover plate 31 from the main structure 30 for cleaning, the first end 23 of the floating part 22, being heavier, will descend under the influence of gravity and move away from the main body. During this process, the second end 24 of the floating part 22 will approach the main body and abut against the first limiting member. The first limiting member will prevent the second end 24 and the floating part 22 from continuing to rotate, thereby preventing the first end 23 of the floating part 22 from moving too far away from the cover plate 31 and potentially hitting the user's fingers.

[0065] In one specific embodiment, the surface of the cover plate 31 facing the water receiving cavity 11 has two protruding supports 33, each support 33 having a hinge hole 34 extending longitudinally along the hinge axis 25. The floating member 22 has hinge axes 25 on opposite sides along the hinge axis 25, with each hinge axis 25 located within one of the two hinge holes 34. Thus, the floating member 22 is hinged to the two supports 33 by rotating the two hinge axes 25 within the two hinge holes 34.

[0066] Furthermore, the cover plate 31 is also provided with two second limiting ribs 35, which are spaced apart along the hinge axis 25. The floating member 22 passes between the two second limiting ribs, thereby limiting the left and right sides of the floating member 22 through the two second limiting ribs, preventing the floating member 22 from moving left and right, causing the hinge axis 25 to fall out of the hinge hole 34, and thus causing the floating member 22 to fall off the cover plate 31. At the same time, the two second limiting ribs can limit the installation of the floating member 22 during installation, preventing the floating member 22 from being installed in the wrong direction, thus having a foolproof effect.

[0067] Furthermore, to avoid installing the hinge shaft 25 within the hinge hole 34, at least one hinge shaft 25 has a chamfered bevel 26 at one end away from the floating member 22. "At least one" means that either two hinge shafts 25 may have a chamfered bevel 26 at one end away from the floating member 22, or only one hinge shaft 25 may have a chamfered bevel 26 at one end away from the floating member 22.

[0068] The two supports 33 may also be provided with draft angles 36 at the hinge holes 34 to facilitate demolding after injection molding. Furthermore, the first limiting rib 32 is connected to the two supports 33, thereby improving the structural strength of the two supports 33.

[0069] In some embodiments of this application, the main structure 30 further includes a water receiving tray 41 and a base station base 40. The water receiving tray 41 is detachably mounted on the base station base 40, and the cover is detachably mounted on the water receiving tray 41. The water receiving tray 41 forms a water receiving cavity 11. A sewage suction pipe 42 is provided on the base station base 40, and a sewage suction port 12 is formed at one end of the sewage suction pipe 42 that extends into the water receiving cavity 11.

[0070] Thus, both the cover and the water tray 41 can be disassembled separately for individual cleaning. Optionally, the water tray 41 is directly attached to the base station base 40, and the cover is attached to the water tray 41, so that the overlapping method facilitates the disassembly and installation of the water tray 41 and the cover.

[0071] In some embodiments, a plurality of filter ribs 43 are provided on the water receiving tray 41. All filter ribs 43 are spaced apart around one end of the sewage suction pipe 42 that extends into the water receiving cavity 11. The sewage entering the sewage suction port 12 can be filtered by the plurality of filter ribs 43, so as to prevent impurities in the sewage from being drawn into the sewage suction pipe 42 and causing blockage of the sewage suction pipe 42.

[0072] Furthermore, the gap between two adjacent ribs can be 2mm-7mm. The sewage suction pipe 42 is installed on the innermost side of the filter rib 43, which is also the lowest position of the bottom surface inside the water receiving tray 41, so that the sewage suction pipe 42 can completely drain the sewage. In actual use, the sewage after cleaning the cleaning components is first filtered through the connecting hole 13 on the drying tray and then flows into the water receiving chamber 11. It then undergoes a second filtration through the filter rib 43 and is finally collected by the sewage suction pipe 42 into the sewage tank in the cleaning base station. In this way, the sewage is filtered twice, which solves the problem of the sewage suction pipe 42 being blocked by impurities.

[0073] In some embodiments of this application, the cleaning base station is further provided with a drying component 50. A water receiving trough 44 is provided on the cover component, with a connecting port at the bottom of the water receiving trough 44. A drying port 45 is provided at one end of the water receiving trough 44 in its longitudinal direction, and the drying port 45 is connected to the drying component 50. When the cleaning device is located at the cleaning base station, at least a portion of the cleaning component of the cleaning device is located within the water receiving trough 44, allowing wastewater generated from cleaning the cleaning component to fall into the water receiving trough 44. The wastewater falling into the water receiving trough 44 enters the water receiving chamber 11 through the connecting hole 13, and is then pumped out of the water receiving chamber 11 through the sewage suction port 12 connected to the water receiving chamber 11.

[0074] After the cleaning components are cleaned, to prevent residual moisture from breeding bacteria and odors, they need to be dried by the drying unit 50. For this purpose, hot air is output from the drying unit 50 and enters the water receiving tank 44 through the drying port 45, drying the cleaning components within. Furthermore, the hot air also cleans the water receiving tank 44 after entering it, thereby reducing water residue within the tank.

[0075] When hot air enters the water receiving tank 44, in addition to cleaning the cleaning components, some of the hot air can also enter the water receiving cavity 11 through the connecting hole 13, thereby allowing the hot air to dry the water receiving cavity 11. In actual use, after the sewage outlet 12 removes the sewage from the water receiving cavity 11, there will still be some sewage residue in the water receiving tank 44 and the water receiving cavity 11. Hot air can reduce the water stains in the water receiving cavity 11, reduce the problem of the water receiving cavity 11 becoming smelly due to not being cleaned for a long time, and improve the user experience.

[0076] The aforementioned clean base stations have at least the following advantages:

[0077] When the sewage inlet 12 is blocked, the detection component 20 installed on the base station body 10 can issue an alarm signal when the water level in the water receiving chamber 11 reaches a certain height. The alarm signal can stop the cleaning device from continuing to clean, or remind the user to clear the blockage, thereby reducing the problem of sewage overflow in the water receiving chamber 11 and improving the user experience.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
