Description

Technical Field

[0001] The present 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 a drying control method. Background Art

[0002] In recent years, more and more highly automated cleaning equipment such as sweeping robots and floor scrubbers have entered the lives of more and more people. These cleaning equipment can greatly reduce people's labor intensity and improve people's lives.

[0003] Cleaning equipment such as sweeping robots and floor scrubbers usually include a base station and a cleaning device. The cleaning device can move in the room autonomously or under human operation, and clean the floor during movement. During the floor cleaning process, the dirt and sewage removed from the floor by the cleaning device will be collected in a sewage container built into the cleaning device. After the floor is cleaned, the cleaning device returns to the base station, and the dirt and sewage collected in its internal sewage container will be transferred to another sewage container set in the base station. The sewage container set in the base station will be connected to the sewage discharge point, and the sewage will eventually be discharged to the sewage discharge point.

[0004] For the cleaning device and the base station, during the whole process of cleaning the ground and discharging sewage, the dirt and sewage pass through the sewage containers inside the two devices respectively, which leads to the retention of dirt and sewage in the sewage containers of the two devices. The dirt and sewage retained in the sewage containers need to be cleaned, otherwise, odor will be generated and bacteria will breed.

[0005] In view of the above problems, in the prior art, a drying air duct is generally provided in the cleaning device, and a heating element is provided in the drying air duct to blow and dry the cleaning brush and sewage container of the cleaning device by generating hot air, thereby avoiding the generation of odor and the breeding of bacteria. However, for the base station, the drying air duct and heating element provided in the above cleaning device are not connected to the sewage container in the base station, and cannot blow and dry the sewage container of the base station. Instead, ultraviolet irradiation and ozone sterilization are generally adopted to sterilize the sewage container of the base station, in order to achieve the effect of avoiding the generation of odor and the breeding of bacteria.

[0006] The above-mentioned ultraviolet irradiation and ozone sterilization methods for base stations have the following problems:

[0007] As for ultraviolet radiation, since the sewage container of the base station is usually not of regular shape, there will be areas inside the sewage container that cannot be irradiated, and it is difficult to avoid odor and bacteria growth in these areas; moreover, the sewage container of the base station is generally provided with a filter, which is used to filter solid waste in the mixed liquid of sewage and dirt. These solid wastes filtered by the filter will block the ultraviolet radiation and further reduce the effect of ultraviolet radiation. As for ozone sterilization, it is difficult for ozone to penetrate into the solid waste, and the sterilization effect on physical waste is small, and it is difficult to achieve a thorough sterilization effect; moreover, based on the consideration of human safety, the concentration of ozone should not be set too high. At the same time, the ozone sterilization method also requires higher sealing of the base station to avoid ozone leakage. Summary of the invention

[0047] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0048] In the cleaning base station and cleaning equipment provided by the embodiment of the present invention, the first fan is connected to the drying air duct, and can generate a flowing airflow in the drying air duct, and the heating device is also connected to the drying air duct to heat the air in the drying air duct, so that the first fan, the heating device and the drying air duct cooperate to generate hot air for drying moisture. On this basis, the first end and the second end of the drying air duct are respectively connected to the area where the cleaning brush is placed and the first sewage container. Under the action of the first fan, firstly, the hot air in the drying air duct can be used to dry the cleaning brush of the cleaning device with hot air when the cleaning device is placed on the cleaning base station, eliminate the sewage on the cleaning brush, thereby avoiding the growth of bacteria and the generation of odor on the cleaning brush. Secondly, the hot air in the drying air duct can also enter the first sewage container of the cleaning base station, and is used to dry the first sewage container of the cleaning base station with hot air, eliminate the sewage in the first sewage container, and avoid the growth of bacteria and the generation of odor in the first sewage container. At the same time, the first fan can be respectively forward and reverse, and when the first fan is operated in different states of forward and reverse, the flow direction of the wind generated in the drying air duct is different. Therefore, in actual implementation, the forward and reverse states of the first fan can be adjusted according to the different processes of drying the cleaning device and the cleaning base station, so as to switch the flow direction of the hot air in the drying air duct. When it is necessary to dry the cleaning brush in the cleaning device, the first fan is set in the forward state, at which time the hot air in the drying air duct flows from the first end to the second end, and the hot air blows toward the cleaning brush, thereby drying the cleaning brush with hot air; and when it is necessary to dry the first sewage container of the cleaning base station, the first fan is set in the reverse state, at which time the hot air in the drying air duct flows from the second end to the first end, and the hot air blows toward the first sewage container, thereby drying the first sewage container with hot air. Compared with the technical solutions of ultraviolet irradiation and ozone sterilization adopted for the sewage container in the cleaning base station in the prior art, in this embodiment, the first sewage container of the cleaning base station is dried with hot air, and the hot air used for drying can flow to any area and corner in the first sewage container, which can more completely and thoroughly eliminate the problem of bacteria breeding and odor generation in the first sewage container, and there will be no health risks to the human body caused by ultraviolet irradiation and ozone sterilization. Finally, hot air drying of the cleaning brush of the cleaning device and hot air drying of the first sewage container of the cleaning base station only requires a motor and an air duct structure, namely the first fan and the drying air duct. There is no need to additionally set up a motor and an air duct structure for hot air drying of the first sewage container of the cleaning base station, which can reduce the cost of cleaning the base station.

[0049] The drying control method provided in the embodiment of the present invention has the same beneficial effects as the above-mentioned cleaning base station and cleaning equipment, and will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0075] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0076] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may 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 herein are interpreted accordingly.

[0077] In one embodiment of the cleaning base station of the present invention, see Figures 1 to 11 The cleaning base station 10 comprises 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 a cleaning device 20, and the cleaning device 20 has a cleaning brush 20-1. The first end of the drying air duct 10-4 is connected to the first sewage 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 air duct 10-4; the first fan 10-2 is connected to the drying air duct 10-4, and is used to generate airflow in the drying air duct 10-4; and the first fan 10-2 includes two states of forward rotation and reverse rotation; when the first fan 10-2 rotates forward, wind is generated in the drying air duct 10-4, flowing from the first end to the second end toward the cleaning brush 20-1; when the first fan 10-2 reverses, wind is generated in the drying air duct 10-4, flowing from the second end to the first end toward the first sewage container 10-1.

[0078] The cleaning device 20 is used to clean the floor, specifically using a cleaning brush 20-1 and the like to clean stains, dust, sewage, etc. on the floor. In the process of cleaning the floor, the cleaning device 20 collects the above-mentioned dirt and the sewage generated in the process of cleaning the above-mentioned dirt into its interior. After cleaning the floor, the cleaning device 20 moves to the cleaning base station 10 and transfers the sewage collected inside it to the first sewage container 10-1 of the cleaning base station 10. The sewage in the first sewage container 10-1 of the cleaning base station 10 can be discharged to the outside through the external drainage point connected thereto. It can be seen from the above process that in the process of the cleaning device 20 and the cleaning base station 10 working, the cleaning device 20 and the cleaning base station 10 will both contact and store sewage in stages. After the first sewage container 10-1 discharges the sewage to the outside, some sewage will still remain inside the cleaning device 20 and in the first sewage container 10-1 of the cleaning base station 10 (attached to the wall inside the cleaning device 20, the cleaning brush 20-1, the wall of the first sewage container 10-1, and there may be some areas where sewage cannot be discharged due to limitations of the structural shape), which will bring the risk of breeding bacteria and generating odor.

[0079] In response to the above problem, in the present embodiment, the first fan 10-2 is connected to the drying air duct 10-4, and can generate a flowing airflow in the drying air duct 10-4, and the heating device 10-3 is also connected to the drying air duct 10-4 to heat the air in the drying air duct 10-4, so that the first fan 10-2, the heating device 10-3 and the drying air duct 10-4 cooperate to generate hot air for drying moisture.

[0080] On this basis, the first end and the second end of the drying air 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, the hot air in the drying air duct 10-4 can be used to perform hot air drying on 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, that is, 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 achieve drying of the second sewage container 20-2, the second fan 20-3 arranged inside the cleaning device can also draw hot air from the cleaning brush 20-1 area to the second sewage container 20-2), eliminate the sewage on the cleaning brush 20-1, thereby avoiding the growth of bacteria and the generation of odor on the cleaning brush 20-1. Secondly, the hot air in the drying air duct 10-4 can also enter the first sewage container 10-1 of the cleaning base station 10, and is used to perform hot air drying on the first sewage container 10-1 of the cleaning base station 10, thereby eliminating the sewage in the first sewage container 10-1 and preventing bacteria from growing and odor in the first sewage container 10-1.

[0081] In this embodiment, the first fan 10-2 can rotate forward and reverse respectively. It can be understood that when the first fan 10-2 is operated in different states of forward and reverse rotation, the flow direction of the wind generated in the drying air duct 10-4 is different. Therefore, in actual implementation, the forward and reverse states of the first fan 10-2 can be adjusted according to the different processes of drying the cleaning device and the cleaning base station 10, so as to switch the flow direction of the hot air in the drying air duct 10-4. When it is necessary to dry the cleaning brush 20-1 in the cleaning device, the first fan 10-2 is set in the forward rotation state. At this time, the hot air in the drying air duct 10-4 flows from its first end to the second end, and the hot air blows toward the cleaning brush 20-1, thereby drying the cleaning brush 20-1 with hot air; and when it is necessary to dry the first sewage container 10-1 of the cleaning base station 10, the first fan 10-2 is set in the reverse rotation state. At this time, the hot air in the drying air duct 10-4 flows from its second end to the first end, and the hot air blows toward the first sewage container 10-1, thereby drying the first sewage container 10-1 with hot air.

[0082] Compared with the technical solutions of ultraviolet irradiation and ozone sterilization adopted for the sewage container in the cleaning base station in the prior art, in the present embodiment, the first sewage container 10-1 of the cleaning base station 10 is dried by hot air, and the hot air used for drying can flow to any area and corner in the first sewage container 10-1, which can more completely and thoroughly eliminate the problems of bacteria breeding and odor generation in the first sewage container 10-1, and there will be no health risks to the human body caused by ultraviolet irradiation and ozone sterilization.

[0083] In this embodiment, hot air drying of the cleaning brush 20-1 of the cleaning device and hot air drying of the first sewage container 10-1 of the cleaning base station 10 only requires one motor and one air duct structure, namely the first fan 10-2 and the drying air duct 10-4. There is no need to additionally set up a motor and an air duct structure for 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 also includes a sewage suction pipe 10-6 and a sewage discharge pipe 10-7; the cleaning device 20 also includes a second sewage container 20-2; the first end of the sewage suction pipe 10-6 is connected to the first sewage container 10-1, and the 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; the first end of the sewage discharge pipe 10-7 is connected to the first sewage container 10-1, and the second end is connected to an external drainage point to discharge the sewage in the first sewage container 10-1 to the outside.

[0085] In this embodiment, by setting up a sewage 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 setting up a sewage 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 cleaning 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 wind flowing from the second end of the sewage suction pipe 10-6 to the first end of the sewage suction pipe 10-6 toward the first sewage container 10-1 when rotating forward.

[0087] In this embodiment, the first fan 10-2 is connected to the first sewage container 10-1, and generates wind from the sewage suction pipe 10-6 to the first sewage container 10-1 in the forward rotation state. According to the negative pressure of the airflow, the wind generated by the first fan 10-2 can suck the sewage in the second sewage container 20-2 into the first sewage container 10-1. Therefore, the first fan 10-2 can be used not only for drying, but also for sewage extraction. For the cleaning base station 10, it is no longer necessary to set up a special motor for sewage extraction, which can reduce 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 sewage suction pipe 10-6 and the first sewage container 10-1, and the first cover plate 10-8 can close the passage between the sewage suction pipe 10-6 and the first sewage container 10-1; when the forward rotation speed of the first fan 10-2 reaches above a first predetermined value, the first cover plate 10-8 opens under the action of the wind generated by the first fan 10-2.

[0089] In this embodiment, a first cover plate 10-8 is provided between the sewage suction pipe 10-6 and the first sewage container 10-1, which can play the role of isolating the sewage suction pipe 10-6 and the first sewage container 10-1; when the first cover plate 10-8 isolates the sewage suction pipe 10-6 and the first sewage container 10-1, it can avoid one-way or two-way exchange of sewage and gas with pollutants between the first sewage container 10-1 and the second sewage container 20-2 through the sewage suction pipe 10-6 when it is not needed, avoid mutual contamination, especially avoid 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 fan 10-2. Specifically, when the first fan 10-2 rotates forward and the speed is low (lower than the first predetermined value), the pressure of the airflow generated by the first fan 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 sewage suction pipe 10-6 and the first sewage container 10-1; when the first fan 10-2 rotates forward and the speed is high (above the first predetermined value), the pressure of the airflow generated by the first fan 10-2 acting on the first cover plate 10-8 is large. Under the action of 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 sewage suction pipe 10-6.

[0091] Therefore, in specific implementation, when it is necessary to pump out sewage (pump the sewage in the second sewage container 20-2 of the cleaning device into the first sewage container 10-1 of the cleaning base station 10), the first motor is set in a forward rotation state, and its rotation speed is set above a first predetermined value, and the first cover plate 10-8 can be opened to connect the second sewage container 20-2 with the first sewage container 10-1, and the sewage in the second sewage container 20-2 is pumped into the first sewage container 10-1. When it is necessary to dry the cleaning brush 20-1 with hot air, the first motor is set in a forward rotation state, and its rotation speed is set below the first predetermined value, and the first cover plate 10-8 is in a closed state, the second sewage container 20-2 and the first sewage container 10-1 are separated, and the second sewage container 20-2 and the first sewage container 10-1 will not contaminate each other, especially the second sewage container 20-2 will not be contaminated by the first sewage container 10-1.

[0092] It is understandable that when the cleaning brush 20-1 is dried with hot air, the required rotation speed of the first fan 10-2 is not very high, and when the sewage in the second sewage container 20-2 is sucked into the first sewage container 10-1, the process needs to drive the liquid to flow and may flow from low to high, and the pressure of the sewage in the second sewage container 20-2 that the first fan 10-2 needs to form needs to be large enough, and the rotation speed of the first fan 10-2 will be relatively higher. 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 of the two situations, which can ensure that the first cover plate 10-8 must be opened when the sewage is sucked, and can ensure that the first cover plate 10-8 must be closed when the hot air drying is performed.

[0093] In one embodiment of the cleaning base station 10, a reset member 10-11 is connected to the first cover plate 10-8, and 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 of closing the channel between the sewage 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, the first cover plate 10-8 is connected to the reset member 10-11, so that the first cover plate 10-8 is in a closed state under normal circumstances, and after the sewage extraction process is completed, the first cover plate 10-8 can effectively return to the closed state from the open state. Therefore, except when it is necessary in the sewage extraction process, in other cases, the first cover plate 10-8 can ensure that the sewage suction pipe 10-6 and the first sewage container 10-1 are separated.

[0095] In the above embodiment, the reset element 10 - 11 may specifically be a torsion spring.

[0096] Selecting a torsion spring as the reset member 10-11 can not only meet the need to reset the first cover plate 10-8, but also reduce the cost of the reset member 10-11 and simplify the structure of the reset member 10-11 due to the simple structure and low cost of the torsion spring.

[0097] In one embodiment of the cleaning base station 10, a second cover plate 10-9 and a driving member are arranged 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 air duct 10-4 and the first sewage container 10-1 can be separated by providing the second cover plate 10-9. A driving member is provided and connected to the second cover plate 10-9, so that the second cover plate 10-9 can be driven to move by the driving member, thereby controlling the opening and closing of the second cover plate 10-9, and thus controlling the connection or disconnection between the drying air duct 10-4 and the first sewage container 10-1 as needed.

[0099] Specifically, in actual application, when sewage extraction is required (or sewage is stored in the first sewage container 10-1), the drying air duct 10-4 and the first sewage container 10-1 need to be separated to prevent sewage from entering the drying air duct 10-4 from the first sewage container 10-1, causing the drying air duct 10-4 to be contaminated. At this time, the second cover plate 10-9 can be controlled to close by the driving member. 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 plate 10-9 can be controlled to open by the driving member, so that the first fan 10-2 and the heating device 10-3 can be used to generate hot air as mentioned above, which is used to dry the cleaning brush 20-1 and the first sewage container 10-1 with hot air.

[0100] In one embodiment of the cleaning 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 providing the third cover plate 10-10. By providing a driving member connected to the third cover plate 10-10, the third cover plate 10-10 can be driven to move by the driving member, thereby controlling the opening and closing of the third cover plate 10-10, and thus controlling the sewage pipe 10-7 and the first sewage container 10-1 to be connected or disconnected as needed.

[0102] In actual application, the third cover plate 10 - 10 is generally controlled to be in an open state only when sewage is discharged to the outside, and in other states, the third cover plate 10 - 10 is usually in a closed state.

[0103] In one embodiment of the cleaning base station 10, a second cover plate 10-9 is arranged between the drying air duct 10-4 and the first sewage container 10-1, and a third cover plate 10-10 is arranged between the sewage pipe 10-7 and the first sewage container 10-1; the cleaning base station 10 also includes a driving member 10-13, and the driving member 10-13 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. The channel between the sewage pipe 10-7 and the first sewage container 10-1 is opened, and the channel between the sewage pipe 10-7 and the first sewage container 10-1 is closed; 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 opened; in the third driving state, the second cover plate 10-9 and the third cover plate 10-10 are both 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 those in the previous two embodiments, and will not be described in detail.

[0105] However, it is necessary to add that the third cover 10-10 and the second cover 10-9 are usually not in the open state at the same time, otherwise sewage will enter the drying air duct 10-4 and pollute the drying air duct 10-4, or the hot air generated by the first fan 10-2 and the heating device 10-3 will enter the sewage pipe 10-7, resulting in the loss of hot air, or the negative pressure of the airflow generated by the first fan 10-2 will re-suck the external sewage into the first sewage container 10-1 and the drying air duct 10-4. In short, the relationship between the third cover 10-10 and the second cover 10-9 is either closed at the same time, or only one of them is in the open state, while the other remains in the closed state.

[0106] Therefore, in this embodiment, only one driving member 10-13 is provided, and the driving member 10-13 has three different driving positions, thereby corresponding to three driving states, respectively realizing the simultaneous closing of the second cover 10-9 and the third cover 10-10, the opening of the second cover 10-9 and the closing of the third cover 10-10, and the closing of the second cover 10-9 and the opening of the third cover 10-10; thereby meeting the needs of realizing the functions of the second cover 10-9 and the third cover 10-10. In addition, one driving member is omitted, which can reduce the cost of the cleaning base station 10.

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

[0108] In this embodiment, a motor screw structure is selected as the driving member 10-13. On the one hand, the motor screw structure belongs to a conventional driving device, which is low in cost and easy to install and configure; and on the other hand, it is also easy to set three different positions on the motor screw structure, so as to facilitate the formation of the above-mentioned three driving states. In addition, by setting a position sensor 10-14, the current position of the motor screw structure can be effectively detected. When it is necessary to switch different driving states, the motor screw structure can be accurately and targetedly controlled in motion, thereby meeting the need to switch different driving states. Specifically, the position sensor 10-14 can be a photoelectric switch.

[0109] In an embodiment of the cleaning base station 10, a filter screen 10-12 is provided in the first sewage container 10-1, and the filter screen 10-12 is communicated with a 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 sewage suction pipe 10-6. The filter screen 10-12 can filter the sewage entering the first sewage container 10-1 during the sewage extraction process, and filter the solid dirt, hair, etc. contained therein to prevent them from entering the first sewage container 10-1 and becoming the source of bacteria breeding and odor in the first sewage container 10-1. Moreover, when the physical dirt and hair in the first sewage container 10-1 are reduced or even eliminated, when the first sewage container 10-1 is dried with hot air, the airflow in the first sewage container 10-1 will be higher and will not be hindered, thereby helping to achieve a better hot air drying effect.

[0111] In summary, the cleaning base station 10 provided by the embodiment of the present invention has a first fan 10-2 connected to the drying air duct 10-4, which can generate a flowing airflow in the drying air duct 10-4, and the heating device 10-3 is also connected to the drying air duct 10-4 to heat the air in the drying air duct 10-4, so that hot air for drying moisture can be generated through the cooperation of the first fan 10-2, the heating device 10-3 and the drying air duct 10-4. On this basis, the first end and the second end of the drying air duct 10-4 are respectively connected to the area where the cleaning brush 20-1 is placed, and connected to the first sewage container 10-1. Under the action of the first fan 10-2, firstly, the hot air in the drying air duct 10-4 can be used to perform hot air drying on the cleaning brush 20-1 of the cleaning device when the cleaning device is placed on the cleaning base station 10, eliminate the sewage on the cleaning brush 20-1, thereby avoiding the growth of bacteria and the generation of odor on the cleaning brush 20-1. Secondly, the hot air in the drying air duct 10-4 can also enter the first sewage container 10-1 of the cleaning base station 10, and is used to perform hot air drying on the first sewage container 10-1 of the cleaning base station 10, eliminate the sewage in the first sewage container 10-1, and avoid the growth of bacteria and the generation of odor in the first sewage container 10-1. At the same time, the first fan 10-2 can be rotated forward and reversed respectively. When the first fan 10-2 is operated in different states of forward and reverse rotation, the flow direction of the wind generated in the drying air duct 10-4 is different. Therefore, in actual implementation, the forward and reverse states of the first fan 10-2 can be adjusted according to the different processes of drying the cleaning device and the cleaning base station 10, thereby switching the flow direction of the hot air in the drying air duct 10-4. When it is necessary to dry the cleaning brush 20-1 in the cleaning device, the first fan 10-2 is set in the forward rotation state. At this time, the hot air in the drying air duct 10-4 flows from its first end to the second end, and the hot air blows toward the cleaning brush 20-1, thereby drying the cleaning brush 20-1 with hot air; and when it is necessary to dry the first sewage container 10-1 of the cleaning base station 10, the first fan 10-2 is set in the reverse rotation state. At this time, the hot air in the drying air duct 10-4 flows from its second end to the first end, and the hot air blows toward the first sewage container 10-1, thereby drying the first sewage container 10-1 with hot air. Compared with the technical solutions of ultraviolet irradiation and ozone sterilization adopted for the sewage container in the cleaning base station 10 in the prior art, in the present embodiment, the first sewage container 10-1 of the cleaning base station 10 is dried by hot air, and the hot air used for drying can flow to any area and corner in the first sewage container 10-1, which can more completely and thoroughly eliminate the problems of bacteria breeding and odor generation in the first sewage container 10-1, and there will be no health risks to the human body caused by ultraviolet irradiation and ozone sterilization.Finally, hot air drying of the cleaning brush 20-1 of the cleaning device and hot air drying of the first sewage container 10-1 of the cleaning base station 10 only requires one motor and one air duct structure, namely the first fan 10-2 and the drying air duct 10-4. There is no need to additionally set up a motor and an air duct structure for 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 comprises a cleaning device and the cleaning base station 10 described in the above embodiment of the present invention.

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

[0114] In this embodiment, the cleaning device includes the cleaning base station 10 described in the above embodiment, which has all the technical features of the cleaning base station 10 in the above embodiment and can of course achieve the same beneficial effects as the cleaning base station 10 in the above embodiment, which will not be repeated.

[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. Fig.15 As shown, the cleaning brush drying mode includes:

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

[0117] Step S12, detecting whether the humidity of the cleaning brush 20-1 drops to a set threshold;

[0118] 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 with step S11.

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

[0120] like Fig.16 As shown, the first sewage container drying mode includes:

[0121] Step S21, controlling the heating device 10-3 to be in a heating state, and controlling the first fan 10-2 to be in a start-up and reverse state, so as to generate hot air toward the first sewage container;

[0122] Step S22, detecting the humidity in the first sewage container;

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

[0124] In the first sewage container drying mode, in step S21, the start-up and control of the heating device 10-3 and the first fan 10-2 have been described in detail in the above-mentioned embodiment of the cleaning base station 10, and will not be repeated here. In step S22, the humidity in the first sewage container is detected, which can be achieved by setting a humidity sensor in 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 passage connecting the cleaning brush 20-1 and the second sewage container 20-2 in the cleaning device is controlled to be in an open state, so that the hot air generated by the first fan 10-2 enters the second sewage container 20-2 along the passage; and

[0127] The second fan 20 - 3 provided in the cleaning device is controlled to start, so as to generate wind flowing toward the second sewage container 20 - 2 in the passage connecting the cleaning brush 20 - 1 and the second sewage container 20 - 2 .

[0128] In this embodiment, through the above steps, the hot air blown to the cleaning brush 20-1 can be further introduced into the second sewage container 20-2 of the cleaning device to dry the second sewage container 20-2 with hot air. In addition, since the second fan 20-3 in the cleaning device sucks the hot air flow, sufficient hot air can enter the second sewage container 20-2, so that the drying effect in the second sewage container 20-2 is better.

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

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

[0131] The cleaning brush 20 - 1 is controlled to rotate intermittently so that the cleaning brush 20 - 1 is directed toward 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 can enable the hot air from the drying air duct 10-4 to blow on different areas of the cleaning brush 20-1 at different times, thereby evenly drying different areas on the cleaning brush 20-1 and avoiding uneven drying and poor drying effect.

[0133] During the hot air drying process, the cleaning brush 20-1 is controlled to rotate intermittently, so that the hot air from the hot air drying duct 10-4 can dry different areas on the cleaning brush 20-1 in different time intervals. In this case, the cleaning brush 20-1 is actually divided into a plurality of fan-shaped areas in the circumferential direction, and each time it rotates, a single or part of the fan-shaped area is subjected to focused hot air drying. It can be understood that in this case, the requirement for the rotation accuracy of the cleaning brush 20-1 is relatively high, so that the required fan-shaped area can be accurately stopped at the angle position 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 direction, or the cleaning brush 20 - 1 rotates alternately in forward and reverse direction.

[0135] In this embodiment, the cleaning brush 20-1 is reversed during hot air drying (opposite to the rotation direction during floor cleaning), so that the bristles on the cleaning brush 20-1 can rebound and reset, relieving the pressure and deformation exerted on the bristles of the cleaning brush 20-1 during floor cleaning, making the cleaning brush 20-1 more fluffy as a whole, 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 alternately rotated forward and reversely. The principle is similar to that described above, and the cleaning brush 20-1 can be made more fluffy as a whole, 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 comprises:

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

[0139] If yes, the cleaning brush drying mode and the first sewage container drying mode are sequentially executed;

[0140] If not, only the cleaning brush drying mode is performed.

[0141] For the cleaning device, sewage will be generated during the self-cleaning process, and the sewage also needs to enter the first sewage container first and then be discharged. Therefore, when the cleaning device is not performing self-cleaning, it is almost meaningless to dry the first sewage container, because the sewage generated by self-cleaning will enter the first sewage container immediately. Therefore, in this embodiment, if the cleaning device is not performing self-cleaning, only the cleaning brush 20-1 is dried, and if the cleaning device has completed self-cleaning, the cleaning brush 20-1 and the first sewage container can be dried separately.

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

[0143] Step S14, controlling the passage between the second sewage container 20-2 and the sewage suction pipe 10-6 in the cleaning device to be closed; and / or controlling the passage between the sewage suction pipe 10-6 and the first sewage container to be closed.

[0144] In step S14, no matter the passage between the second sewage container 20-2 and the sewage suction pipe 10-6 is closed, or the passage between the sewage suction pipe 10-6 and the first sewage container is closed, the effect achieved is that the passage between the first sewage container and the second sewage container 20-2 is disconnected. Therefore, during the hot air drying of the cleaning brush 20-1, the first sewage container will not interfere with or negatively affect the hot air drying of the cleaning brush 20-1 and the second sewage container 20-2.

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

[0146] Step S24, controlling the channel between the drying air duct 10-4 and the first sewage container to be closed; and / or controlling the channel between the first sewage container and the sewage pipe 10-7 to be closed.

[0147] In step S24, after the first sewage container is dried by hot air, the passage between the drying air duct 10-4 and the first sewage container is closed, so that the drying air duct 10-4 is separated from the first sewage container, so that in the subsequent cleaning base station operation, when the first sewage container is pumping sewage, it is ensured that sewage will not enter the drying air duct 10-4. When the passage between the first sewage container and the sewage pipe 10-7 is closed, the first sewage container is disconnected from the external drainage point, and the first sewage container can store sewage sucked from the cleaning device when pumping sewage.
