For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] Figure 1 is a schematic structural diagram of the floor sweeping robot base station provided by the embodiment of the present application from the back view. Figure 2 is a schematic structural diagram of the floor sweeping robot base station provided by the embodiment of the present application from the front view.

[0032] It should be noted that in the present application, Figure 1 and Figure 2 only show the partial structure related to the high-temperature steam disinfection function of the floor sweeping robot base station, and do not specifically display the overall outline or complete structure of the entire floor sweeping robot base station.

[0033] Those skilled in the art can understand that based on the inventive concept provided by the embodiment of the present application, corresponding adjustments and modifications can also be made, and the relevant structures for high-temperature steam disinfection provided by the embodiment of the present application can be applied to any type or structure of floor sweeping robot base station, which is not specifically limited herein.

[0034] As Figure 1 and Figure 2 shown, the base station of the floor cleaning robot may include: a base station body 10, a cleaning seat housing 20, a tray assembly 30, and a steam generating assembly 40.

[0035] Among them, the base station body 10 is the basic framework structure of the entire base station of the floor cleaning robot. It provides installation positions and accommodation spaces for various functional devices and structures. For example, a water tank 11 for storing clean water, a circuit board 12 integrating one or more functional circuits, and so on.

[0036] The cleaning seat housing 20 is a structural component formed at the end of the base station body 10. It is described independently of the base station body 10 because it can form a docking space for the floor cleaning robot to enter, without limiting the specific implementation of the cleaning seat housing 20. For example, the cleaning seat housing 20 may be a part extended from the base station body 10, or may be a component independent of the main structure of the base station body 10, or a structure composed of multiple different components.

[0037] In this embodiment, for the convenience of description, the two surfaces of the cleaning seat housing facing away from each other are called the inner wall surface and the outer wall surface. The "inner wall surface" refers to the side facing the docking space, while the outer wall surface is the side facing away from the docking space.

[0038] Specifically, please continue to refer to Figure 1 and Figure 2 , the cleaning seat housing 20 includes: a housing top 21 and a housing side wall 22.

[0039] Among them, a connection structure 23 is formed on the housing top 21, and it is rigidly connected to the end of the base station body 10 based on the connection structure 23. In this embodiment, since the structure of the housing top 21 forms the top of the docking space and is located above the floor cleaning robot docked therein, this part of the structure is called the housing top.

[0040] The housing side wall 22 is a wall surface extending a certain distance along the axial direction from the circumferential edge of the housing top 21. The specific extended distance can be set according to actual needs and is not specifically limited here.

[0041] In addition, the housing side wall 22 also has a notch 24 with a preset width. The notch 24 is generally located on the front of the base station of the floor cleaning robot to form an opening for the floor cleaning robot to enter and leave the docking space. In other words, the housing side wall 22 is not a continuous wall surface surrounding the circumferential edge, and at least a part of the circumferential edge of the housing top 22 does not extend to form the housing side wall 22.

[0042] The tray assembly 30 is a component for carrying the floor cleaning robot entering the docking space. It is fixed on the cleaning base housing 20 by a detachable connection method, and together they cooperate to form the above-mentioned docking space for the floor cleaning robot to dock and enter.

[0043] In this embodiment, "detachable connection" means a connection method between two or more structural components that can be separated in a non-destructive manner through a specific method and can be assembled together again. It has the characteristics of repeatability and non-destructiveness.

[0044] At least one exhaust hole is also provided in the above-mentioned tray assembly 30. The exhaust hole is opened towards the docking space and can eject high-temperature steam. The specific number, position, and arrangement of the exhaust holes can be determined according to actual needs and are not specifically limited here.

[0045] The steam generation assembly 40 is a general term for a series of components that cooperate with each other to generate high-temperature steam meeting the usage requirements. It can be fixedly arranged on the outer wall surface of the cleaning base housing 20. On the one hand, it is connected to the water tank 11 through a liquid transmission channel to obtain clear water from the water tank 11 to generate the required high-temperature steam; on the other hand, the steam output end for outputting high-temperature steam is connected to the exhaust hole provided in the tray assembly 30 through a steam transmission channel, so that the high-temperature steam can be ejected into the docking space through the exhaust hole to clean and disinfect the mop of the floor cleaning robot.

[0046] Specifically, please continue to refer to Figure 1 and Figure 2 , the steam generation assembly 40 includes: a steam generator 41, a water pump 42, and a solenoid valve 43.

[0047] Among them, the steam generator 41 has a clear water input end and a steam output end, and is fixedly arranged on the back of the outer wall surface of the cleaning base housing. It heats the injected clear water through the internal heating wire and converts it into high-temperature steam and outputs it from the steam output end.

[0048] The water pump 42 is connected to the water tank 11 through a first connecting water pipe 51 and is connected to the clear water input end of the steam generator 41 through a second connecting water pipe 52. When starting to operate, it pumps the clear water stored in the water tank 11 into the steam generator 41 to generate the required high-temperature steam.

[0049] The solenoid valve 43 is a valve controlled by an electrical signal. It can be arranged between the first connecting water pipes 51 and controls whether the first connecting water pipes 51 are connected by opening and closing, so as to realize the control of the clear water supply.

[0050] Preferably, when the connection structure 23 with a relatively small radial dimension is used at the top 21 of the housing of the cleaning base housing 20, a gap in the axial direction is formed between the ends of the base body 10 of the base station. The solenoid valve 43 can be installed in this gap, making full use of the internal space of the base body of the base station.

[0051] In some embodiments, as Figure 3 shown, the tray assembly 30 includes: a tray body 31 and a cleaning bracket 32.

[0052] Among them, the tray body 31 is fixedly connected to the side wall 22 of the housing of the above-mentioned cleaning base housing 20 in a detachable connection manner, so as to cooperate to form a docking space. The tray body 31, as the main structure of the entire tray assembly, is also provided with a sewage accommodation space for accommodating the dirty water and dirt generated during the cleaning of the mop of the floor cleaning robot.

[0053] This sewage accommodation space is an open space, which is communicated with the docking space and can directly receive the dirty water and dirt generated by the floor cleaning robot parked therein during the automatic cleaning process. In this embodiment, for the convenience of description, the open position of the sewage accommodation space is called the open end.

[0054] Specifically, the tray body 31 can be roughly divided into an inclined portion 311 and a receiving portion 312 along the direction in which the floor cleaning robot enters and exits the docking space. The inclined portion 311 is at a position close to the opening of the docking space, while the receiving portion 312 is at a position far from the opening of the docking space.

[0055] Among them, the receiving portion 312 has an outer peripheral edge 312a protruding in the axial direction, and a sewage accommodation space with an open top is formed by the slightly protruding outer peripheral edge 312a. The cleaning bracket 32 can be clamped and fixed on the outer peripheral edge 312a, so as to be erected at the open end of the sewage accommodation space.

[0056] The inclined portion 311 forms an inclined surface with a preset slope. The bottom of this inclined surface is connected to the ground, and the top of the inclined surface extends to the receiving portion 312 and is connected to the top end of at least a part of the outer peripheral edge, so as to facilitate the floor cleaning robot to enter and exit the docking space.

[0057] Preferably, an additional guiding structure 314 can also be provided on the inclined surface. This guiding structure 314 extends from the bottom to the top of the inclined surface, and can better guide the floor cleaning robot to correctly enter the docking space and avoid deviation and misalignment.

[0058] During actual use, as Figure 2 shown, when the tray assembly 30 is fixed to the cleaning base housing 20, the outer peripheral edge 312a of its receiving portion will be engaged with the side wall 22 of the housing, and the inclined surface formed by the inclined portion 311 is located at the notch of the side wall 22 of the housing.

[0059] Specifically, please continue to refer to Figure 3 , the tray body 31 may further include: first limiting structures 313 provided on both sides of the inclined surface.

[0060] Wherein, the first limiting structure 313 is a locking mechanism adapted to a second limiting structure provided on the side wall of the housing. The two cooperate with each other so that the tray assembly 30 can be locked and fixed on the cleaning base housing along the inclined direction of the above-mentioned inclined surface.

[0061] The cleaning bracket 32 is a structure erected at the open end of the sewage accommodation space. One or more of the above exhaust ports 33 are opened on the cleaning bracket 32, facing the bottom of the floor sweeping robot parked therein, and can spray high-temperature steam.

[0062] Specifically, the cleaning bracket 32 can be fixedly installed on the tray body by selecting any suitable type according to actual needs. For example, the above-mentioned detachable connection method, or the integral molding method, or even the non-detachable connection method such as bonding.

[0063] Exemplarily, Figure 3 shows a cleaning bracket 32 composed of six long strip-shaped connecting rods 321 and two annular structures 322. The exhaust holes 33 are opened at the top ends of the long strip-shaped connecting rods 321.

[0064] Three long strip-shaped connecting rods 321 and one annular structure 322 form a set of bracket units. Two sets of bracket units are arranged in parallel. Among each set of bracket units, the three long strip-shaped connecting rods 321 respectively extend outward from the annular structure 322 in different directions to connect with the tray body 31.

[0065] In some embodiments, please continue to refer to Figure 3 , the tray assembly 30 further includes: bracket silica gel 34 snap-fitted and fixed on the cleaning bracket 32.

[0066] Specifically, as Figures 1 to 3 shown, the above-mentioned steam transmission channel for transmitting high-temperature steam includes: a first steam transmission pipe 61 located inside the tray body, a second steam transmission pipe 62 located outside the tray body, and a silica gel connector 63.

[0067] Wherein, the first steam transmission pipe 61 runs through the inside of the entire cleaning bracket 32, communicates with all the exhaust holes 33 and forms a connection hole at the central part of the outer peripheral edge 312a. In other words, through this connection hole, high-temperature steam can reach each exhaust hole 33 and be ejected from the exhaust holes 33.

[0068] The second steam transmission pipeline 62 is a pipeline that connects the connection hole and the steam output end of the steam generator. Any suitable type of pipeline can be used according to actual needs, and specific limitations are not made here.

[0069] The silica gel connector 63 is arranged at the connection between the connection hole and the second steam transmission pipeline 62, which can effectively prevent high-temperature water vapor from leaking during transmission and ensure that the water vapor can enter the first steam transmission pipeline 61 completely.

[0070] To fully describe the floor cleaning robot base station of this application embodiment, the following will describe in detail the specific implementation process and working principle of high-temperature steam disinfection and cleaning of the floor cleaning robot base station in combination with specific examples.

[0071] First, after the floor cleaning robot enters the docking space of the floor cleaning robot base station and completes the program of cleaning the rag, through the corresponding electronic control signal, under the control of the power control board integrated with the power control circuit, power is supplied to the steam generator 41 to increase the temperature of the heating wire inside it.

[0072] After heating for a preset time and the heating wire reaches the ideal temperature, the main control board integrated with the control circuit can send the corresponding electronic control signal to control the solenoid valve 43 to open and start the water pump 42 to operate, pumping the clear water stored in the water tank into the steam generator 41.

[0073] The clear water entering the steam generator 41 will be vaporized into water vapor at high temperature after contacting the heating wire. The generated water vapor enters the cleaning bracket 32 through the steam transmission channel and is sprayed onto the rag of the floor cleaning robot through the exhaust holes 33 on the cleaning bracket 32 for sterilization and disinfection.

[0074] Secondly, the process of generating high-temperature steam for sterilization and disinfection is intermittent. Specifically, after the water pump 42 runs continuously for a preset time, the main control board sends an electronic control signal to control the solenoid valve 43 to close and stop the water pump 42 from running, waiting for the clear water in the steam generator 41 to be evaporated completely. After the clear water in the steam generator 41 is evaporated completely, then control the solenoid valve 43 to open again and start the water pump 42 to run to supply water to the steam generator 41, thereby generating high-temperature steam. The generated high-temperature steam continues to be sprayed onto the rag of the floor cleaning robot through the exhaust holes 33 for sterilization and disinfection.

[0075] Finally, the above process of sterilization and disinfection can be repeated a predetermined number of times until the sterilization and disinfection work is completed.

[0076] In summary, the floor cleaning robot base station provided by the embodiments of the present application can effectively kill bacteria, viruses, and other microorganisms on the mop through steam disinfection, thereby improving the cleaning efficiency and effect. This disinfection method is more environmentally friendly and safe than traditional chemical disinfectants, does not produce harmful residues, and also brings a healthier and more comfortable cleaning experience. Users do not need to worry about the impact of harmful residues that may be generated during the cleaning process on the health of family members, and can also enjoy a cleaner and tidier home environment, enhancing the user experience.

[0077] Moreover, the steam disinfection function provided by the floor cleaning robot base station can effectively remove stains and residues on the mop, reduce the wear and damage of the mop, and thus extend the service life of the mop. This is of great significance for reducing the cleaning costs in households or commercial premises.

[0078] In addition, the steam disinfection function is integrated on the floor cleaning robot base station, which can simplify the cleaning process. Users do not need to manually disinfect the mop and can automatically perform steam disinfection. This greatly reduces the operation difficulty and time cost for users.

[0079] It should be noted that the embodiments of the present application describe the disinfection and sterilization principles of the above-mentioned high-temperature steam by taking a floor cleaning robot with a mop at the bottom as an example. Those skilled in the art can understand that based on the technical solutions disclosed in the embodiments of the present application, it can also be applied to other different types of floor cleaning robots and their supporting floor cleaning robot base stations.

[0080] The above content is a further detailed description of the present application in combination with specific / preferred embodiments, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application.
