Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0049] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0050] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0051] The utility model discloses a cleaning system, such as Figure 1 and Figure 2 As shown, the cleaning system includes a cleaning device 100 and a base station 200. The cleaning device 100 can be docked on the base station 200, and the base station 200 is used to adapt to the cleaning device 100. In one application scenario, the cleaning device 100 is a floor scrubber, and the base station 200 is a base station suitable for a floor scrubber. In another application scenario, the cleaning device 100 is a vacuum cleaner, and the base station 200 is a base station suitable for a vacuum cleaner. Of course, the cleaning device 100 includes but is not limited to floor scrubbers and vacuum cleaners, and can also be other devices with cleaning functions, which are not described one by one here. Similarly, the base station 200 includes but is not limited to base stations suitable for floor scrubbers and vacuum cleaners, and can also be other base stations adapted to cleaning devices.

[0052] The following description takes the cleaning device 100 as a floor scrubber and the base station 200 as a base station suitable for a floor scrubber as an example, but based on the above description, it can be seen that the protection scope of the present utility model is not limited thereby.

[0053] like Figures 3 to 5As shown, the floor scrubber is provided with a negative pressure unit 110, a dirt storage container 130 and a cleaning liquid tank 140, wherein the negative pressure unit 110 is used to generate suction force, under the action of the suction force, external dirt can be sucked into the dirt storage container 130 through the suction port 161 of the floor brush assembly 160 at the bottom of the floor scrubber, and the airflow passing through the dirt storage container 130 is discharged from the floor scrubber by the negative pressure unit 110, thereby achieving tasks such as cleaning of the surface to be cleaned and self-cleaning. Specifically, the negative pressure unit 110 is a fan, which can generate suction airflow (suction force) when working, and the suction airflow makes the suction port 161 and the dirt storage container 130 in a negative pressure state.

[0054] The cleaning liquid tank 140 is used to store cleaning liquid. A fluid channel is formed between the cleaning liquid tank 140 and the roller brush 162 of the floor brush assembly 160. The liquid in the cleaning liquid tank 140 can wet the roller brush 162 through the fluid channel to achieve wet cleaning of the surface to be cleaned, self-cleaning of the roller brush, and other tasks.

[0055] The housing of the floor scrubber is provided with a main unit air duct port 120 that can be communicated with the negative pressure unit 110, a sewage outlet that is communicated with the sewage storage container 130, and a liquid replenishing port 141 that is selectively communicated with the cleaning liquid tank 140. The liquid replenishing port 141 is distributed close to the main unit air duct port 120, and the main unit air duct port 120 is distributed close to the negative pressure unit 110. The sewage outlet is used to provide an opening for the sewage in the sewage storage container 130 to be discharged to the base station 200 after the floor scrubber is docked with the base station 200.

[0056] A cover plate 131 is pivotally connected to the sewage outlet, and the cover plate 131 has a first state when the sewage outlet is covered and a second state when the sewage outlet is open. When the floor scrubber is docked with the base station 200, the cover plate 131 switches from the first state to the second state under the action of the base station 200. At this time, under the action of the negative pressure suction force of the base station 200, the dirt in the sewage storage container 130 can be sucked into the base station 200.

[0057] In this embodiment, the negative pressure unit 110 is connected to either the dirt storage container 130 or the main machine air duct port 120. The above-mentioned "connection to either one" is achieved by a valve structure 300 built into the floor scrubber. When the floor scrubber performs a dirt suction task during cleaning or self-cleaning of the surface to be cleaned, the negative pressure unit 110 is connected to the dirt storage container 130. At this time, the negative pressure unit 110 is not connected to the main machine air duct port 120. Under the action of the suction force generated by the negative pressure unit 110, external dirt is sucked into the dirt storage container 130. When the floor scrubber is docked with the base station 200, the negative pressure unit 110 is connected to the main engine air duct opening 120, and there is no conduction between the negative pressure unit 110 and the dirt storage container 130. At this time, the suction force generated by the negative pressure unit 110 acts on the main engine air duct opening 120, and the main engine air duct opening 120 acts on the base station 200. Therefore, the base station 200 does not need to be equipped with a negative pressure driving source, thereby simplifying the overall structure of the cleaning system, facilitating installation and maintenance, and also reducing the production cost of the cleaning system.

[0058] like Figures 6 to 9 As shown, the base station 200 includes a base station body, and the base station body is provided with a base station air duct opening 210 and a base station sewage outlet 220, wherein the base station air duct opening 210 is used to dock with the host air duct opening 120, and the base station sewage outlet 220 is used to dock with the sewage outlet of the sewage storage container 130. When the floor scrubber is docked with the base station 200, the host air duct opening 120 is connected to the base station air duct opening 210, and the sewage outlet of the sewage storage container 130 is connected to the base station sewage outlet 220, and the sewage in the sewage storage container 130 can be sucked into the base station 200 under the action of negative pressure.

[0059] Specifically, Fig.10 and Fig.11 As shown, at least one of the air duct opening 210 of the base station and the air duct opening 120 of the host is provided with a sealing structure 400, and the sealing structure 400 is used to form a sealed connection between the air duct opening 210 of the base station and the air duct opening 120 of the host when the scrubber is docked with the base station 200. That is to say, when the scrubber is docked with the base station 200, the connection between the air duct opening 120 of the host and the air duct opening 210 of the base station, and the connection between the sewage outlet of the sewage storage container 130 and the sewage outlet 220 of the base station are in a sealed state.

[0060] Among them, the sealing structure 400 is a sealing ring fixedly installed on the inner wall or outer wall of the base station air duct opening 210 and the host air duct opening 120; or, the sealing structure 400 includes ribs (not shown) and sealing grooves (not shown), one of the ribs and the sealing grooves is arranged at the base station air duct opening 210, and the other is arranged at the host air duct opening 120. When the floor scrubber is docked with the base station 200, the ribs are accommodated in the sealing grooves to form a labyrinth sealing structure.

[0061] The base station air duct opening 210 is connected to the negative pressure unit 110 through the main unit air duct opening 120 in response to the docking action between the floor scrubber and the main body of the base station, so that the base station sewage outlet 220 is in a negative pressure state. That is, after the floor scrubber is docked with the base station 200, the negative pressure unit 110 is connected to the base station air duct opening 210 through the main unit air duct opening 120. When the base station sewage outlet 220 is in a negative pressure state, the dirt in the sewage storage container 130 is sucked to the base station 200 through the sewage outlet and the base station sewage outlet 220, thereby realizing automatic cleaning of the dirt in the sewage storage container 130.

[0062] The air duct opening 210 of the base station is closer to the negative pressure unit 110 than the sewage outlet 220 of the base station. Among them, closer can be judged by a preset direction, a straight-line distance, etc. The preset direction can be the docking direction between the floor scrubber and the base station body. For example, if the floor scrubber is docked to the base station in a downward insertion manner, the preset direction is the vertical direction up and down. If the floor scrubber is docked to the base station horizontally, the preset direction is the horizontal direction. The preset direction can also be a specified direction, such as a specified direction parallel to the bottom surface of the base station. The straight-line distance can be the distance between the center of the air duct opening 210 of the base station to the center of the negative pressure unit 110, and the distance between the center of the sewage outlet 220 of the base station to the center of the negative pressure unit 110.

[0063] Alternatively, in the docking direction between the floor scrubber and the main body of the base station, the base station air duct opening 210 is arranged between the base station sewage outlet 220 and the negative pressure unit 110. The above arrangement of the base station air duct opening 210 can shorten the airflow path between the base station air duct opening 210 and the negative pressure unit 110 to reduce wind resistance, maximize the suction force acting on the base station 200, and improve the sewage extraction efficiency. The above "docking direction" can refer to: the direction from top to bottom. Specifically, the base station air duct opening 210 is set upward, and the host air duct opening 120 is set downward.

[0064] like Figure 7 and Fig. 9 As shown, the housing of the base station 200 is provided with an outer protrusion 230, and the base station air duct opening 210 is formed at the top of the outer protrusion 230 and opens upward. Fig. 9 As shown, the sewage outlet 220 of the base station is also arranged on the outer protrusion 230, and the sewage outlet 220 of the base station is distributed toward the sewage storage container 130. The outer protrusion 230 can be understood as a structure on the base station 200 for docking with the floor scrubber. The outer protrusion 230 extends along the docking direction and is block-shaped or column-shaped, and the shape is not limited.

[0065] A dirt collection container 240 is provided on the main body of the base station, and the base station air duct opening 210 and the base station sewage outlet 220 are respectively connected to the dirt collection container 240. When the base station air duct opening 210 is connected to the negative pressure unit 110, the dirt collection container 240 connected to the base station air duct opening 210 is also in a negative pressure state, and then the base station sewage outlet 220 connected to the dirt collection container 240 is also in a negative pressure state. As a result, the dirt in the dirt storage container 130 can enter the dirt collection container 240 under the action of negative pressure, completing the automatic cleaning of the dirt.

[0066] In order to ensure the sewage discharge effect and the sewage holding capacity of the sewage collection container 240, the connection between the base station air duct opening 210 and the sewage collection container 240, and the connection between the base station sewage discharge port 220 and the sewage collection container 240 are respectively arranged close to the top of the sewage collection container 240. Specifically, the base station air duct opening 210 is connected with the sewage collection container 240 through the first channel 211, and the base station sewage discharge port 220 is connected with the sewage collection container 240 through the second channel 221, wherein the first channel 211 is shorter than the second channel 221.

[0067] Furthermore, a filtering structure (not shown) is provided on the main body of the base station, and the air duct opening 210 of the base station is connected to the dirt collection container 240 through the filtering structure. The filtering structure has the function of filtering the airflow, preventing the dirt in the dirt collection container 240 from entering the air duct opening 120 of the host through the air duct opening 210 of the base station, and is used to isolate the dirt in the dirt collection container 240.

[0068] The filter structure is disposed on the top of the outer side of the waste collection container 240 and is connected to the waste collection container 240. On the one hand, it can prevent the filter structure from occupying the volume of the waste collection container 240, and on the other hand, it can also facilitate the replacement of the filter structure. Among them, the filter structure can be HEPA, activated carbon, etc.

[0069] The main body of the base station is also provided with a sewage pipe (not shown) connected to the sewage collection container 240, and the sewage pipe is connected to the underground pipeline (not shown) for sewage discharge. When the sewage in the sewage storage container 130 enters the sewage collection container 240, it is discharged from the base station 200 through the sewage pipe. In one embodiment, in order to simplify the structure of the base station 200, the main body of the base station is not provided with a sewage collection container 240, and the base station sewage outlet 220 on the main body of the base station is connected to the sewage pipe. The base station air duct port 210 is connected to the sewage pipe. After the scrubber is docked with the base station 200, the sewage pipe responds to the suction airflow of the base station air duct port 210 and is in a negative pressure state, so that the base station sewage outlet 220 is in a negative pressure state, and the sewage in the sewage storage container 130 enters the sewage pipe through the sewage outlet and the base station sewage outlet 220, and is discharged through the sewage pipe.

[0070] The main body of the base station is also provided with a liquid injection port 260 that cooperates with the liquid replenishing port 141. The liquid injection port 260 is used to replenish liquid into the cleaning liquid tank 140. After the floor scrubber is docked with the base station 200, if the cleaning liquid tank 140 is in a state of little or no liquid, the liquid injection port 260 will replenish liquid into the cleaning liquid tank 140. The liquid injection port 260 can be connected to a municipal water source or to a liquid replenishing container 250. When the liquid injection port 260 is connected to the liquid replenishing container 250, the liquid replenishing container 250 needs to be provided on the main body of the base station.

[0071] The liquid injection port 260 is disposed on the outer protrusion 230. Figure 6 As shown, in one case, the injection port 260 is located in the base station air duct port 210, and the liquid replenishment port 141 is correspondingly located in the host air duct port 120; in another case, as shown Fig. 9 As shown, the injection port 260 is located outside the base station air duct opening 210 and is adjacent to the base station air duct opening 210 . At this time, the liquid replenishment port 141 is located outside the host air duct opening 120 and is adjacent to the host air duct opening 120 .

[0072] Attached Figure 7 Schematic diagram of a base station 200 provided with both a dirt collecting container 240 and a liquid replenishing container 250; Figure 8 This is a schematic diagram when the base station 200 is only provided with a sewage collection container 240. Of course, the base station 200 may also be provided with no sewage collection container 240 and no liquid replenishing container 250, and only with a base station sewage outlet 220 and a liquid injection port 260. In this case, the base station sewage outlet 220 is connected to a sewage pipe, and the liquid injection port 260 is connected to a municipal water source.

[0073] In this embodiment, a first charging terminal 270 is provided on the housing of the base station 200, and the first charging terminal 270 is distributed near the outer protrusion 230 or is provided on the outer protrusion 230. A second charging terminal 150 that cooperates with the first charging terminal 270 is also provided on the housing of the floor scrubber. After the floor scrubber is docked with the base station 200, the first charging terminal 270 and the second charging terminal 150 are in contact and connected.

[0074] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
