Description

Technical Field

[0001] This application relates to the field of cleaning products such as floor scrubbers and sweeping robots, and in particular to a cleaning base station, cleaning equipment, and drying control method. 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 reduce the labor intensity of people to a greater extent and improve people's lives.

[0003] Cleaning equipment such as robotic vacuum cleaners and floor scrubbers typically consist of a base station and a cleaning device. The cleaning device can move autonomously or under human operation within a room, cleaning the floor as it moves. During cleaning, the dirt and wastewater collected by the cleaning device are collected in a built-in wastewater container. After cleaning, the cleaning device returns to the base station, and the collected dirt and wastewater are transferred to another wastewater container located within the base station. This wastewater container is connected to a wastewater discharge point, where the wastewater is ultimately discharged.

[0004] For cleaning devices and base stations, during the entire process of cleaning the ground and discharging sewage, dirt and sewage pass through their internal sewage containers. This inevitably results in dirt and sewage remaining in the sewage containers, which need to be cleaned to prevent odors and bacterial growth.

[0005] To address the aforementioned issues, existing technologies typically incorporate drying ducts within cleaning devices, housing heating elements. Hot air is generated to blow and dry the cleaning brushes and wastewater containers, preventing odors and bacterial growth. However, for base stations, the drying ducts and heating elements in the aforementioned cleaning devices are not connected to the wastewater containers within the base station and cannot directly blow or dry them. Instead, ultraviolet irradiation and ozone sterilization are generally used to disinfect the wastewater containers, aiming to prevent odors and bacterial growth.

[0006] The aforementioned methods of ultraviolet irradiation and ozone sterilization for base stations have the following problems:

[0007] Regarding ultraviolet (UV) irradiation, the wastewater containers of base stations are typically not regularly shaped, resulting in areas inside that cannot be irradiated. These areas are difficult to prevent from producing odors and breeding bacteria. Furthermore, the wastewater containers usually contain filters to remove solid waste from the wastewater and sludge mixture. This filtered solid waste also blocks UV radiation, further reducing its effectiveness. As for ozone sterilization, ozone has difficulty penetrating the solid waste, resulting in limited sterilization and incomplete disinfection. Moreover, for safety reasons, the ozone concentration should not be set too high. Additionally, ozone sterilization requires a higher level of airtightness from the base station to prevent ozone leakage. Summary of the Invention

[0008] This application provides a cleaning base station, cleaning equipment, and drying control method to solve the problems in the prior art where ultraviolet irradiation and ozone sterilization for cleaning base stations result in incomplete cleaning and sterilization, easy bacterial growth and odor generation, and potential health risks.

[0009] The present invention provides a cleaning base station, comprising a base, a first wastewater container, a first fan, a heating device, and a drying duct; the base is used to place the cleaning device, which has a cleaning brush; a first end of the drying duct is connected to the first wastewater container, and a second end is connected to an area on the base that accommodates the cleaning brush; the heating device is used to heat the air in the drying duct; the first fan is connected to the drying duct and is used to generate airflow in the drying duct; and the first fan has two states: forward rotation and reverse rotation; when the first fan rotates forward, airflow from the first end to the second end towards the cleaning brush is generated in the drying duct; when the first fan rotates in reverse, airflow from the second end to the first end towards the first wastewater container is generated in the drying duct.

[0010] The cleaning base station further includes a suction pipe and a discharge pipe; the cleaning device further includes a second wastewater container; the first end of the suction pipe is connected to the first wastewater container, and the second end is connected to the second wastewater container of the cleaning device when the cleaning device is placed on the base, so as to allow the wastewater stored in the second wastewater container of the cleaning device to flow into the first wastewater container of the cleaning base station; the first end of the discharge pipe is connected to the first wastewater container, and the second end is connected to an external drainage point, so as to discharge the wastewater in the first wastewater container to the outside.

[0011] The first blower is also connected to the first sewage container. When the first blower rotates forward, it generates airflow from the second end of the suction pipe to the first end of the suction pipe and toward the first sewage container.

[0012] A first cover plate is provided between the suction pipe and the first sewage container, which can close the channel between the suction pipe and the first sewage container; when the forward rotation speed of the first blower reaches a first predetermined value, the first cover plate is opened by the wind generated by the first blower.

[0013] A reset member is connected to the first cover plate. The reset member applies force to the first cover plate so that the first cover plate remains in a closed state, closing the channel between the suction pipe and the first sewage container, when the forward rotation speed of the first fan is less than a first predetermined value.

[0023] The cleaning brush drying mode includes:

[0024] Step S11: Control the heating device to heat; start the first fan and control the first fan to rotate forward to generate hot air for the cleaning brush;

[0025] Step S12: Detect whether the humidity of the cleaning brush has decreased to a set threshold.

[0026] Step S13: If the detection result of step S12 is yes, the cleaning brush drying mode ends; if the detection result of step S12 is no, continue to step S11.

[0027] The first wastewater container drying mode includes:

[0028] Step S21: The heating device is controlled to be in the heating state, and the first blower is controlled to be in the start and reverse state to generate hot air to the first sewage container.

[0029] Step S22: Detect the humidity inside the first wastewater container;

[0030] Step S23: If the detection result of step S22 is yes, then the drying mode of the first sewage container ends; if the detection result of step S22 is no, then continue to step S21.

[0031] Step S11 of the cleaning brush drying mode further includes:

[0032] The channel connecting the cleaning brush and the second wastewater container within the cleaning device is kept open, allowing hot air generated by the first blower to enter the second wastewater container along the channel; and

[0046] Step S24: Control the closure of the passage between the drying air duct and the first sewage container; and / or, control the closure of the passage between the first sewage container and the sewage pipe.

[0047] The technical solutions provided in this application have the following advantages compared with the prior art:

[0048] The cleaning base station and cleaning equipment provided in this embodiment of the invention have a first fan connected to a drying duct, which generates airflow within the drying duct. A heating device is also connected to the drying duct to heat the air within it. Through the combined action of the first fan, heating device, and drying duct, hot air is generated for drying moisture. The first and second ends of the drying duct are connected to the area where the cleaning brush is placed and a first wastewater container, respectively. Under the action of the first fan, firstly, the hot air in the drying duct can be used to dry the cleaning brush of the cleaning device when it is placed on the cleaning base station, removing wastewater from the brush and preventing bacterial growth and odor. Secondly, the hot air in the drying duct can also enter the first wastewater container of the cleaning base station to dry it, removing wastewater and preventing bacterial growth and odor. Simultaneously, the first fan can rotate forward and reverse. When the first fan operates in different forward and reverse states, the direction of the airflow generated within the drying duct is different. Therefore, in actual implementation, the forward and reverse rotation of the first fan can be adjusted according to the different processes of drying the cleaning device and the cleaning base station, thereby switching the flow direction of the hot air in the drying duct. When the cleaning brush in the cleaning device needs to be dried, the first fan is set to the forward rotation state. At this time, the hot air in the drying duct flows from its first end to its second end, and the hot air blows onto the cleaning brush, thereby drying the cleaning brush. When the first sewage container in the cleaning base station needs to be dried, the first fan is set to the reverse rotation state. At this time, the hot air in the drying duct flows from its second end to its first end, and the hot air blows onto the first sewage container, thereby drying the first sewage container. Compared with the existing technology that uses ultraviolet irradiation and ozone sterilization for sewage containers in cleaning base stations, in this embodiment, the hot air used for drying the first sewage container of the cleaning base station can flow to any area and corner of the first sewage container, which can more completely and thoroughly eliminate the problem of bacteria growth and odor in the first sewage container, and there is no health risk to the human body caused by ultraviolet irradiation and ozone sterilization. Finally, the cleaning brush of the cleaning device and the first sewage container of the cleaning base station are dried with hot air. Only one motor and one air duct structure are needed, namely the first fan and the drying air duct. There is no need to set up an additional motor and air duct structure for the hot air drying of the first sewage container of the cleaning base station, which can reduce the cost of the cleaning base station.

[0049] The drying control method provided in this embodiment of the invention has the same beneficial effects as the above-mentioned cleaning base station and cleaning equipment, and will not be described in detail here. Attached Figure Description

[0074] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0076] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0077] In one embodiment of the clean base station of the present invention, see [reference needed] Figures 1 to 11 The cleaning base station 10 includes a base 10-5, a first sewage container 10-1, a first fan 10-2, a heating device 10-3, and a drying air duct 10-4. The base 10-5 is used to place the cleaning device 20, which has a cleaning brush 20-1. The first end of the drying duct 10-4 is connected to the first wastewater container 10-1, and the second end is connected to the area on the base 10-5 that accommodates the cleaning brush 20-1. The heating device 10-3 is used to heat the air in the drying duct 10-4. The first fan 10-2 is connected to the drying duct 10-4 and is used to generate airflow in the drying duct 10-4. The first fan 10-2 has two states: forward rotation and reverse rotation. When the first fan 10-2 rotates forward, airflow from the first end to the second end towards the cleaning brush 20-1 is generated in the drying duct 10-4. When the first fan 10-2 rotates in reverse, airflow from the second end to the first end towards the first wastewater container 10-1 is generated in the drying duct 10-4.

[0078] The cleaning device 20 is used to clean the ground, specifically by using a cleaning brush 20-1 to remove stains, dust, and wastewater. During the cleaning process, the cleaning device 20 collects the aforementioned dirt and wastewater generated during the cleaning process. After cleaning, the cleaning device 20 moves to the cleaning base station 10 and transfers the collected wastewater to the first wastewater container 10-1 of the cleaning base station 10. The wastewater in the first wastewater container 10-1 of the cleaning base station 10 can be discharged externally through an external drainage point connected to it. As can be seen from the above process, during the operation of the cleaning device 20 and the cleaning base station 10, both the cleaning device 20 and the cleaning base station 10 come into contact with and periodically store wastewater. After the first sewage container 10-1 discharges sewage, some sewage will remain inside the cleaning device 20 and in the first sewage container 10-1 of the cleaning base station 10 (adhering to the inner wall of the cleaning device 20, the cleaning brush 20-1, the wall of the first sewage container 10-1, and some areas may have sewage that cannot be discharged due to structural shape limitations). This will bring the risk of bacterial growth and odor.

[0079] To address the aforementioned issues, in this embodiment, the first fan 10-2 is connected to the drying duct 10-4, generating a flowing airflow within the drying duct 10-4. The heating device 10-3 is also connected to the drying duct 10-4, heating the air within the drying duct 10-4. Thus, through the combined action of the first fan 10-2, the heating device 10-3, and the drying duct 10-4, hot air for drying moisture can be generated.

[0080] Based on this, the first and second ends of the drying duct 10-4 are respectively connected to the area where the cleaning brush 20-1 is placed and to the first sewage container 10-1. Under the action of the first fan 10-2, firstly, the hot air in the drying duct 10-4 can be used to dry the cleaning brush 20-1 of the cleaning device when the cleaning device is placed on the cleaning base station 10 (this part of the hot air can also enter other areas of the cleaning device, such as the area where sewage is stored, i.e., the second sewage container 20-2 mentioned below. The second sewage container 20-2 and the cleaning brush 20-1 are usually connected, so it can also be used to dry the second sewage container 20-2; in order to dry the second sewage container 20-2, the second fan 20-3 set inside the cleaning device can also draw hot air from the area of ​​the cleaning brush 20-1 to the second sewage container 20-2), to remove the sewage on the cleaning brush 20-1, thereby avoiding the growth of bacteria and the generation of odors on the cleaning brush 20-1. Secondly, the hot air in the drying duct 10-4 can also enter the first sewage container 10-1 of the cleaning base station 10 to dry the first sewage container 10-1 of the cleaning base station 10 with hot air, eliminate the sewage in the first sewage container 10-1, and prevent bacteria from growing and odors from being produced in the first sewage container 10-1.

[0081] In this embodiment, the first fan 10-2 can rotate in both forward and reverse directions. It is understood that when the first fan 10-2 operates in different forward and reverse states, the airflow direction generated within the drying duct 10-4 is different. Therefore, in actual implementation, the forward and reverse rotation states of the first fan 10-2 can be adjusted according to the different drying processes of the cleaning device and the cleaning base station 10, thereby switching the flow direction of the hot air within the drying duct 10-4. When the cleaning brush 20-1 in the cleaning device needs to be dried, the first fan 10-2 is set to the forward rotation state. At this time, the hot air in the drying air duct 10-4 flows from its first end to its second end and blows the hot air onto the cleaning brush 20-1, thereby drying the cleaning brush 20-1 with hot air. When the first sewage container 10-1 of the cleaning base station 10 needs to be dried, the first fan 10-2 is set to the reverse rotation state. At this time, the hot air in the drying air duct 10-4 flows from its second end to its first end and blows the hot air onto the first sewage container 10-1, thereby drying the first sewage container 10-1 with hot air.

[0082] Compared to the existing technology that uses ultraviolet irradiation and ozone sterilization for wastewater containers in clean base stations, in this embodiment, the first wastewater container 10-1 of the clean base station 10 is dried with hot air. The hot air used for drying can flow to any area and corner of the first wastewater container 10-1, which can more completely and thoroughly eliminate the problem of bacteria growth and odor in the first wastewater container 10-1, and there is no health risk to the human body caused by ultraviolet light irradiation and ozone sterilization.

[0083] In this embodiment, the hot air drying of the cleaning brush 20-1 of the cleaning device and the hot air drying of the first sewage container 10-1 of the cleaning base station 10 only require one motor and one air duct structure, namely the first fan 10-2 and the drying air duct 10-4. It is not necessary to set up an additional motor and air duct structure for the hot air drying of the first sewage container 10-1 of the cleaning base station 10, which can reduce the cost of the cleaning base station 10.

[0084] In one embodiment of the cleaning base station 10, the cleaning base station 10 further includes a suction pipe 10-6 and a discharge pipe 10-7; the cleaning device 20 further includes a second sewage container 20-2; a first end of the suction pipe 10-6 is connected to the first sewage container 10-1, and a second end is connected to the second sewage container 20-2 of the cleaning device 20 when the cleaning device 20 is placed on the base 10-5, so that the sewage stored in the second sewage container 20-2 of the cleaning device 20 flows into the first sewage container 10-1 of the cleaning base station 10; a first end of the discharge pipe 10-7 is connected to the first sewage container 10-1, and a second end is connected to an external drainage point, so that the sewage in the first sewage container 10-1 is discharged to the outside.

[0085] In this embodiment, by providing a suction pipe 10-6, the sewage in the second sewage container 20-2 of the cleaning device can be transferred to the first sewage container 10-1 of the cleaning base station 10; and by providing a discharge pipe 10-7, the sewage stored in the first sewage container 10-1 can be discharged to an external drainage point.

[0086] In one embodiment of the clean base station 10, the first fan 10-2 is also connected to the first sewage container 10-1, and the first fan 10-2 generates airflow from the second end of the suction pipe 10-6 to the first end of the suction pipe 10-6 and toward the first sewage container 10-1 when rotating forward.

[0087] In this embodiment, the first blower 10-2 is connected to the first sewage container 10-1, and when rotating in the forward direction, it generates airflow from the suction pipe 10-6 towards the first sewage container 10-1. Due to the negative pressure of this airflow, the airflow generated by the first blower 10-2 can draw sewage from the second sewage container 20-2 into the first sewage container 10-1. Thus, the first blower 10-2 can be used not only for drying but also for sewage extraction. For the cleaning base station 10, it eliminates the need for a dedicated motor for sewage extraction, reducing the cost of the cleaning base station 10.

[0088] In one embodiment of the cleaning base station 10, a first cover plate 10-8 is provided between the suction pipe 10-6 and the first sewage container 10-1. The first cover plate 10-8 can close the channel between the suction pipe 10-6 and the first sewage container 10-1. When the forward rotation speed of the first fan 10-2 reaches a first predetermined value, the first cover plate 10-8 is opened by the wind generated by the first fan 10-2.

[0089] In this embodiment, a first cover plate 10-8 is provided between the suction pipe 10-6 and the first sewage container 10-1, which can isolate the suction pipe 10-6 and the first sewage container 10-1. When the first cover plate 10-8 isolates the suction pipe 10-6 and the first sewage container 10-1, it can prevent the one-way or two-way exchange of sewage and pollutant-laden gas between the first sewage container 10-1 and the second sewage container 20-2 through the suction pipe 10-6 when not needed, thus avoiding mutual contamination, especially preventing the second sewage container 20-2 from being contaminated by the first sewage container 10-1.

[0090] Furthermore, the opening and closing of the first cover plate 10-8 is determined by the pressure of the airflow generated by the first blower 10-2. Specifically, when the first blower 10-2 is rotating forward and at a low speed (below a first predetermined value), the pressure of the airflow generated by the first blower 10-2 acting on the first cover plate 10-8 is small, and the first cover plate 10-8 is in a closed state, isolating the suction pipe 10-6 and the first sewage container 10-1; when the first blower 10-2 is rotating forward and at a high speed (above the first predetermined value), the pressure of the airflow generated by the first blower 10-2 acting on the first cover plate 10-8 is large, and under this pressure, the first cover plate 10-8 is in an open state, and the second sewage container 20-2 is connected to the first sewage container 10-1 through the suction pipe 10-6.

[0091] Therefore, in practical implementation, when it is necessary to pump out wastewater (to draw wastewater from the second wastewater container 20-2 of the cleaning device into the first wastewater container 10-1 of the cleaning base station 10), the first motor is set to the forward rotation state, and its speed is set above a first predetermined value. This allows the first cover plate 10-8 to open, connecting the second wastewater container 20-2 and the first wastewater container 10-1, allowing the wastewater in the second wastewater container 20-2 to be drawn into the first wastewater container 10-1. When it is necessary to use hot air to dry the cleaning brush 20-1, the first motor is set to the forward rotation state, and its speed is set below the first predetermined value. The first cover plate 10-8 is then closed, separating the second wastewater container 20-2 and the first wastewater container 10-1. This prevents mutual contamination between the two containers, especially the second wastewater container 20-2, which is not contaminated by the first wastewater container 10-1.

[0092] It is understandable that when hot air drying the cleaning brush 20-1, the required rotation speed of the first fan 10-2 is not very high. However, when pumping sewage from the second sewage container 20-2 into the first sewage container 10-1, this process requires driving the liquid to flow, possibly from low to high pressure. Therefore, the pressure exerted by the first fan 10-2 on the sewage in the second sewage container 20-2 needs to be sufficiently high, resulting in a relatively higher rotation speed for the first fan 10-2. Therefore, for the setting of the first predetermined value in this embodiment, it is only necessary to take an intermediate value between the rotation speeds in the two cases. This ensures that the first cover 10-8 is always open during sewage pumping and always closed during hot air drying.

[0093] In one embodiment of the cleaning base station 10, a reset member 10-11 is connected to the first cover plate 10-8. The reset member 10-11 applies force to the first cover plate 10-8 so that the first cover plate 10-8 remains in a closed state, closing the channel between the suction pipe 10-6 and the first sewage container 10-1, when the forward rotation speed of the first fan 10-2 is less than a first predetermined value.

[0094] In this embodiment, connecting the first cover plate 10-8 to the reset member 10-11 ensures that the first cover plate 10-8 is in a closed state under normal circumstances, and that after the sludge suction process is completed, the first cover plate 10-8 can effectively return from the open state to the closed state. Thus, except when necessary during the sludge suction process, the first cover plate 10-8 ensures separation between the sludge suction pipe 10-6 and the first sewage container 10-1.

[0095] In the above embodiments, the reset member 10-11 can specifically be a torsion spring.

[0096] Choosing a torsion spring as the reset component 10-11 not only meets the need to reset the first cover plate 10-8, but also reduces the cost of the reset component 10-11 and simplifies its structure due to the simple structure and low cost of the torsion spring.

[0097] In one embodiment of the clean base station 10, a second cover plate 10-9 and a driving member are provided between the drying air duct 10-4 and the first sewage container 10-1. The second cover plate 10-9 is connected to the driving member and moves under the drive of the driving member. The movement of the second cover plate 10-9 can open and close the channel between the drying air duct 10-4 and the first sewage container 10-1.

[0098] In this embodiment, the drying duct 10-4 and the first wastewater container 10-1 can be separated by providing a second cover plate 10-9. By providing a driving component connected to the second cover plate 10-9, the second cover plate 10-9 can be moved, thereby controlling its opening and closing. This allows for the control of whether the drying duct 10-4 and the first wastewater container 10-1 are connected or disconnected as needed.

[0099] Specifically, in practical applications, when sludge removal is required (or when the first sewage container 10-1 contains sewage), the drying duct 10-4 and the first sewage container 10-1 need to be separated to prevent sewage from entering the drying duct 10-4 from the first sewage container 10-1 and contaminating the drying duct 10-4. At this time, the second cover 10-9 can be closed by controlling the drive unit. When the sewage inside the first sewage container 10-1 has been discharged to the outside, and the cleaning brush 20-1 or the first sewage container 10-1 needs to be dried, the second cover 10-9 can be opened by controlling the drive unit. This allows the first fan 10-2 and the heating device 10-3 to generate hot air for drying the cleaning brush 20-1 and the first sewage container 10-1, as mentioned above.

[0100] In one embodiment of the clean base station 10, a third cover plate 10-10 and a driving member are provided between the sewage pipe 10-7 and the first sewage container 10-1. The third cover plate 10-10 is connected to the driving member and moves under the drive of the driving member. The movement of the third cover plate 10-10 can open and close the channel between the sewage pipe 10-7 and the first sewage container 10-1.

[0101] In this embodiment, the sewage pipe 10-7 and the first sewage container 10-1 can be separated by setting a third cover plate 10-10. A driving component connected to the third cover plate 10-10 can be used to move the third cover plate 10-10, thereby controlling its opening and closing. This allows for the control of whether the sewage pipe 10-7 and the first sewage container 10-1 are connected or disconnected as needed.

[0102] In practical applications, the third cover 10-10 is generally only kept in the open state when sewage is being discharged. In other states, the third cover 10-10 is usually kept in the closed state.

[0103] In one embodiment of the cleaning base station 10, a second cover plate 10-9 is provided between the drying air duct 10-4 and the first sewage container 10-1, and a third cover plate 10-10 is provided between the sewage pipe 10-7 and the first sewage container 10-1; the cleaning base station 10 further includes a driving member 10-13, which is connected to the second cover plate 10-9 and the third cover plate 10-10; the driving member 10-13 has a first driving state, a second driving state, and a third driving state; in the first driving state, the second cover plate 10-9 is in an open state, and the third cover plate 10-10 is in a closed state, so that the drying air duct 10-4 and the first sewage container 10-1 are connected between the second cover plate 10-9 and the third cover plate 10-10. In the second driving state, the second cover plate 10-9 is in a closed state and the third cover plate 10-10 is in an open state, so that the channel between the drying air duct 10-4 and the first sewage container 10-1 is closed and the channel between the sewage pipe 10-7 and the first sewage container 10-1 is open; in the third driving state, both the second cover plate 10-9 and the third cover plate 10-10 are in a closed state, so that the channel between the drying air duct 10-4 and the first sewage container 10-1 is closed and the channel between the sewage pipe 10-7 and the first sewage container 10-1 is closed.

[0104] In this embodiment, the arrangement and function of the second cover plate 10-9 and the third cover plate 10-10 are the same as in the previous two embodiments, and will not be described again.

[0105] However, it is necessary to further clarify that the third cover 10-10 and the second cover 10-9 are usually not open simultaneously. Otherwise, sewage would enter the drying duct 10-4, contaminating it, or hot air generated by the first fan 10-2 and the heating device 10-3 would enter the drain pipe 10-7, resulting in heat loss. Alternatively, the negative pressure of the airflow generated by the first fan 10-2 could draw external sewage back into the first sewage container 10-1 and the drying duct 10-4. In short, the relationship between the third cover 10-10 and the second cover 10-9 is either that they are both closed, or that only one of them is open while the other remains closed.

[0106] Therefore, in this embodiment, only one driving component 10-13 is provided. This driving component 10-13 has three different driving positions, thereby corresponding to three driving states, which respectively realize the simultaneous closing of the second cover plate 10-9 and the third cover plate 10-10, the opening of the second cover plate 10-9 and the closing of the third cover plate 10-10, and the closing of the second cover plate 10-9 and the opening of the third cover plate 10-10; thus, it can meet the needs of the second cover plate 10-9 and the third cover plate 10-10 in realizing their respective functions. Moreover, one driving component is saved, which can reduce the cost of the cleaning base station 10.

[0107] In one embodiment of the clean base station 10, see further... Figures 12-14 The driving component 10-13 includes a motor lead screw structure. The first driving state, the second driving state, and the third driving state of the driving component 10-13 correspond to three different moving positions of the motor lead screw structure, respectively. The cleaning base station 10 also includes a position sensor 10-14, which is used to detect the position state of the motor lead screw structure in order to identify and control the operating state of the driving component.

[0108] In this embodiment, a motor lead screw structure is selected as the driving component 10-13. On one hand, the motor lead screw structure is a conventional driving device, which is low in cost and easy to install and configure. On the other hand, it is easy to set three different positions on the motor lead screw structure, thus facilitating the formation of the three driving states mentioned above. Furthermore, by setting a position sensor 10-14, the current position of the motor lead screw structure can be effectively detected. When switching between different driving states is required, accurate and targeted motion control of the motor lead screw structure can be performed, thereby meeting the need for switching between different driving states. Specifically, the position sensor 10-14 can be a photoelectric switch.

[0109] In one embodiment of the cleaning base station 10, a filter screen 10-12 is provided inside the first sewage container 10-1, and the filter screen 10-12 is connected to the connection port between the first sewage container 10-1 and the sewage suction pipe 10-6.

[0110] In this embodiment, a filter screen 10-12 is provided at the connection point between the first sewage container 10-1 and the suction pipe 10-6. This filter screen 10-12 can filter the sewage entering the first sewage container 10-1 during the sewage suction process, filtering out solid dirt, hair, and other contaminants contained therein, preventing them from entering the first sewage container 10-1 and becoming a source of bacterial growth and odor. Moreover, when there are fewer or no objects, dirt, or hair in the first sewage container 10-1, the airflow within the first sewage container 10-1 will be higher and unobstructed during hot air drying, thus contributing to a better hot air drying effect.

[0111] In summary, the cleaning base station 10 provided in this embodiment of the invention has a first fan 10-2 connected to a drying duct 10-4, which generates airflow within the drying duct 10-4. A heating device 10-3 is also connected to the drying duct 10-4, heating the air within it. Thus, through the combined action of the first fan 10-2, the heating device 10-3, and the drying duct 10-4, hot air for drying moisture can be generated. Furthermore, the first and second ends of the drying duct 10-4 are connected to the area where the cleaning brush 20-1 is placed and to the first wastewater container 10-1, respectively. Under the action of the first fan 10-2, the hot air within the drying duct 10-4 can be used to dry the cleaning brush 20-1 of the cleaning device when it is placed on the cleaning base station 10, eliminating wastewater on the cleaning brush 20-1 and preventing bacterial growth and odors. Secondly, the hot air in the drying duct 10-4 can also enter the first wastewater container 10-1 of the cleaning base station 10 to dry the first wastewater container 10-1, eliminating wastewater and preventing bacterial growth and odor. Simultaneously, the first fan 10-2 can rotate forward and reverse. When the first fan 10-2 operates in different forward and reverse states, the airflow direction within the drying duct 10-4 is different. Therefore, in actual implementation, the forward and reverse rotation of the first fan 10-2 can be adjusted according to the different drying processes of the cleaning device and the cleaning base station 10, thereby switching the direction of the hot air flow within the drying duct 10-4. When the cleaning brush 20-1 in the cleaning device needs to be dried, the first fan 10-2 is set to the forward rotation state. At this time, the hot air in the drying air duct 10-4 flows from its first end to its second end and blows the hot air onto the cleaning brush 20-1, thereby drying the cleaning brush 20-1 with hot air. When the first sewage container 10-1 of the cleaning base station 10 needs to be dried, the first fan 10-2 is set to the reverse rotation state. At this time, the hot air in the drying air duct 10-4 flows from its second end to its first end and blows the hot air onto the first sewage container 10-1, thereby drying the first sewage container 10-1 with hot air. Compared to the existing technology that uses ultraviolet irradiation and ozone sterilization for the sewage container in the cleaning base station 10, in this embodiment, the first sewage container 10-1 of the cleaning base station 10 is dried with hot air. The hot air used for drying can flow to any area and corner of the first sewage container 10-1, which can more completely and thoroughly eliminate the problem of bacteria growth and odor in the first sewage container 10-1, and there is no health risk to the human body caused by ultraviolet irradiation and ozone sterilization.Finally, the cleaning brush 20-1 of the cleaning device is dried with hot air, and the first sewage container 10-1 of the cleaning base station 10 is dried with hot air. Only one motor and one air duct structure are needed, namely the first fan 10-2 and the drying air duct 10-4. There is no need to set up an additional motor and air duct structure for the hot air drying of the first sewage container 10-1 of the cleaning base station 10, which can reduce the cost of the cleaning base station 10.

[0112] In one embodiment of the cleaning device of the present invention, the cleaning device includes a cleaning apparatus and a cleaning base station 10 as described in the above embodiments of the present invention.

[0113] Specifically, the cleaning device includes a floor scrubber or a sweeping robot.

[0114] In this embodiment, the cleaning equipment includes the cleaning base station 10 described in the above embodiments, which has all the technical features of the cleaning base station 10 in the above embodiments, and can naturally achieve the same beneficial effects as the cleaning base station 10 in the above embodiments, so it will not be described again.

[0115] In one embodiment of the drying control method of the present invention, the drying control method includes a cleaning brush drying mode and a first sewage container drying mode. Wherein, as... Figure 15 As shown, the cleaning brush drying mode includes:

[0116] Step S11: Control the heating device 10-3 to heat; start the first fan 10-2 and control the first fan 10-2 to rotate forward to generate hot air toward the cleaning brush 20-1;

[0117] Step S12: Detect whether the humidity of the cleaning brush 20-1 has decreased to a set threshold.

[0118] Step S13: If the detection result of step S12 is yes, then the cleaning brush drying mode ends; if the detection result of step S12 is no, then continue to step S11.

[0119] In this cleaning brush drying mode, the starting and control of the heating device 10-3 and the first fan 10-2 in step S11 have been described in detail in the aforementioned embodiment of the cleaning base station 10, and will not be repeated here. The detection of the humidity of the cleaning brush 20-1 in step S12 can be specifically achieved by setting a humidity sensor in the area where the cleaning brush 20-1 is located.

[0120] like Figure 16 As shown, the first wastewater container drying mode includes:

[0121] Step S21: The heating device 10-3 is controlled to be in the heating state, and the first blower 10-2 is controlled to be in the start and reverse state to generate hot air to the first sewage container;

[0122] Step S22: Detect the humidity inside the first wastewater container;

[0123] Step S23: If the detection result of step S22 is yes, then the drying mode of the first sewage container ends; if the detection result of step S22 is no, then continue to step S21.

[0124] In this first sewage container drying mode, the starting and control of the heating device 10-3 and the first fan 10-2 in step S21 have been described in detail in the aforementioned embodiment of the cleaning base station 10, and will not be repeated here. The detection of humidity inside the first sewage container in step S22 can be specifically achieved by installing a humidity sensor inside the first sewage container.

[0125] In one embodiment of the drying control method, step S11 of the cleaning brush drying mode further includes:

[0126] The channel connecting the cleaning brush 20-1 and the second wastewater container 20-2 within the cleaning device is kept open, allowing hot air generated by the first blower 10-2 to enter the second wastewater container 20-2 along the channel; and

[0127] The second fan 20-3 installed in the control cleaning device is started to generate airflow toward the second wastewater container 20-2 in the channel connecting the cleaning brush 20-1 and the second wastewater container 20-2.

[0128] In this embodiment, through the above steps, the hot air blown towards the cleaning brush 20-1 can be further introduced into the second wastewater container 20-2 of the cleaning device for hot air drying of the second wastewater container 20-2. Furthermore, because the second fan 20-3 inside the cleaning device draws in this hot airflow, sufficient hot air can enter the second wastewater container 20-2, resulting in a better drying effect inside the second wastewater container 20-2.

[0129] In one embodiment of the drying control method, step S11 of the cleaning brush drying mode further includes:

[0130] Control the cleaning brush to rotate continuously at 20-1; or

[0131] The cleaning brush 20-1 is controlled to rotate intermittently so that the cleaning brush 20-1 faces the second end of the drying air duct 10-4 in different areas in the circumferential direction at different times.

[0132] In this embodiment, during the hot air drying process, the continuous rotation of the cleaning brush 20-1 allows the hot air from the drying air duct 10-4 to be blown onto different areas of the cleaning brush 20-1 at different times, so as to evenly dry different areas of the cleaning brush 20-1 and avoid uneven drying or poor drying effect.

[0133] During the hot air drying process, the cleaning brush 20-1 is controlled to rotate intermittently, allowing the hot air from the drying duct 10-4 to dry different areas of the cleaning brush 20-1 at different time intervals. This effectively divides the cleaning brush 20-1 into multiple fan-shaped areas circumferentially, with each rotation focusing on drying a single or partial fan-shaped area. Understandably, this requires high precision in the rotation of the cleaning brush 20-1 to ensure that the desired fan-shaped area stops precisely at the angle directly facing the hot air blowing from the drying duct 10-4.

[0134] In one embodiment of the drying control method, the cleaning brush 20-1 rotates in reverse, or the cleaning brush 20-1 rotates alternately in both forward and reverse directions.

[0135] In this embodiment, the cleaning brush 20-1 is reversed during hot air drying (opposite to the rotation direction during the floor cleaning process), which allows the bristles on the cleaning brush 20-1 to spring back and reset, relieving the pressure and deformation experienced by the bristles during the floor cleaning process. This makes the cleaning brush 20-1 fluffier overall, which is more conducive to hot air drying and achieves a better drying effect.

[0136] During the hot air drying process, the cleaning brush 20-1 is rotated alternately in both forward and reverse directions. The principle is similar to that described above, which can also make the cleaning brush 20-1 fluffier overall, thereby achieving a better drying effect during the hot air drying process.

[0137] In one embodiment of the drying control method, the drying control method further includes:

[0138] Check whether the cleaning device performs self-cleaning;

[0139] If so, the cleaning brush drying mode and the first sewage container drying mode will be executed sequentially.

[0140] If not, only the cleaning brush drying mode will be executed.

[0141] For the cleaning device, wastewater is generated during the self-cleaning process. This wastewater needs to enter the first wastewater container before being discharged. Therefore, drying the first wastewater container is almost meaningless when the cleaning device is not performing self-cleaning, because wastewater generated during self-cleaning will immediately enter the first wastewater container. Therefore, in this embodiment, if the cleaning device is not performing self-cleaning, only the cleaning brush 20-1 is dried; if the cleaning device has completed self-cleaning, both the cleaning brush 20-1 and the first wastewater container can be dried.

[0142] In one embodiment of the drying control method, the cleaning brush drying mode further includes:

[0143] Step S14: Close the passage between the second sewage container 20-2 and the suction pipe 10-6 in the cleaning device; and / or close the passage between the suction pipe 10-6 and the first sewage container.

[0144] In step S14, whether the passage between the second wastewater container 20-2 and the suction pipe 10-6 is closed, or the passage between the suction pipe 10-6 and the first wastewater container is closed, the effect achieved is that the passage between the first wastewater container and the second wastewater container 20-2 is disconnected. Therefore, during the hot air drying process of the cleaning brush 20-1, the first wastewater container will not interfere with or negatively affect the hot air drying of the cleaning brush 20-1 and the second wastewater container 20-2.

[0145] The first wastewater container drying mode also includes:

[0146] Step S24: Control the closure of the passage between the drying air duct 10-4 and the first sewage container; and / or, control the closure of the passage between the first sewage container and the sewage pipe 10-7.

[0147] In step S24, after the first wastewater container is dried by hot air, the channel between the drying duct 10-4 and the first wastewater container is closed, separating the drying duct 10-4 from the first wastewater container. This ensures that wastewater will not enter the drying duct 10-4 when the first wastewater container is pumped out during subsequent cleaning of the base station. Closing the channel between the first wastewater container and the sewage pipe 10-7 disconnects the first wastewater container from the external drainage point, allowing the first wastewater container to store the wastewater pumped out by the cleaning device during pumping.
