[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0041] With reference to Figures 1-11, the present application discloses a cleaning system, which generally includes a surface cleaning device 101 and a base station 102 for docking the surface cleaning device 101. After the surface cleaning device 101 is docked to the base station 102, it can perform self-cleaning. The surface cleaning device 101 is used to clean the surface to be cleaned. The surface cleaning device 101 generally includes a dirt recovery system and a cleaning liquid supply system. The cleaning liquid supply system generally includes a cleaning liquid tank 3 and a water pump. The water pump sprays the sucked cleaning liquid through a pipeline to the surface to be cleaned or the roller brush. The dirt recovery system generally includes a suction motor 4 and a recovery box 1. The airflow generated by the suction motor 4 recovers the dirt on the ground into the recovery box 1. The surface cleaning device 101 includes a main body 10 and a cleaning head 30 and a handle 20 respectively arranged on the main body 10. The main body 10 includes an outer casing, which defines a storage space for accommodating the recovery box 1 and the cleaning liquid tank 3. The outer casing can be an integrally molded structure. The one-piece outer casing can greatly improve the waterproof performance of the main body 10 and prevent liquid from entering the interior of the main body 10.

[0042] Referring to Figures 6 and 7 , the base station 102 is used to dock with the surface cleaning device 101. The base station 102 is typically provided with a receiving slot for accommodating the cleaning head 30 to facilitate self-cleaning of the roller brush. The base station 102 also typically has a charging function. Once the surface cleaning device 101 is docked, the battery pack 52 within the surface cleaning device 101 can be charged.

[0043] In order to avoid the user having to stop the surface cleaning device 101 first and then lift it up and put it into the base station 102, the present application has made certain improvements to the base station 102. Referring to Figure 6, an opening is set on one side of the base station 102, and the opening is set into a slope, so that the cleaning head 30 can directly drive into the base station 102 without lifting it. That is, along the forward direction of the surface cleaning device 101, the cleaning head 30 can move directly from the surface to be cleaned to the storage space defined by the base station 102. The direction of the arrow in Figure 2 is the forward direction of the surface cleaning device. In this way, there will be no part of the dirt left on the surface to be cleaned due to the shutdown of the surface cleaning device 101. In order to facilitate charging, the main body 10 is provided with a charging connector 54 that can be docked with the base station 102. The recycling box 1 and the charging connector 54 are respectively arranged on opposite sides of the main body 10 along the forward direction of the surface cleaning device 101. It is also for the convenience of taking out the recycling box 1. Since the cleaning head 30 is driven into the base station 102, some improvements need to be made to the relevant structures to facilitate the removal and placement of the cleaning liquid tank 3 and the recovery tank 1. Referring to Figures 3, 8, and 9, in this embodiment, the recovery tank 1 and the cleaning liquid tank 3 can be removed simultaneously, and the removal direction is opposite to the direction in which the cleaning head 30 travels into the base station 102. The arrow in Figure 3 indicates the direction in which the recovery tank and the cleaning liquid tank are removed. In this way, after the user drives the surface cleaning device 101 into the base station 102, the user only needs to adjust the main body 10 to an upright position, and the surface cleaning device 101 can be charged, self-cleaned, etc. After self-cleaning is completed, the user can also directly remove the recovery tank 1 and the cleaning liquid tank 3 at the same time without adjusting the direction of the surface cleaning device 101, which is more convenient.

[0044] In order to save costs and to make it more convenient for users to take and put the recycling box 1 and the cleaning liquid tank 3, the recycling box 1 and the cleaning liquid tank 3 are integrally formed, and the recycling box 1 is arranged behind the cleaning liquid tank 3 along the forward direction of the surface cleaning device 101. Specifically, two independent spaces can be provided in an integrally formed container, and the two independent spaces are arranged side by side along the direction of travel, the one near the front is used to hold the cleaning liquid, and the one near the rear is used to hold dirt. This design not only saves costs but also saves space. A holding space is defined on the rear side of the main body 10, and the integrally formed recycling box 1 is detachably installed in the holding space. When the recycling box 1 is installed, the cleaning liquid tank 3 is located between the recycling box 1 and the inner plate of the main body 10. A suction motor 4 is also provided in the outer casing, and the air outlet of the suction motor 4 faces the recycling box 1. A circulation channel 26 is defined between the cleaning liquid tank 3 and the outer casing, and the airflow discharged from the air outlet flows out of the main body 10 through the circulation channel 26.

[0045] To further increase the volume of the recovery tank 1 and effectively reduce the generation of water vapor therein, the height of the recovery tank 1 along the height direction of the main body 10 is greater than two-thirds the height of the outer casing. Designing the sewage tank as high as possible, on the one hand, increases the effective volume of the sewage tank. The effective volume here refers to the maximum capacity of the sewage tank that can hold sewage (generally not exceeding 80% of the sewage tank volume). The sewage tank is generally equipped with a water-full detection device or a water-full shutoff device. The water-full detection device is configured to send a signal when the sewage reaches a certain water level, causing the controller to control the suction motor 4 to stop operation. The water-full detection device can be a detection electrode or a light detection device. The water-full shutoff device is generally a float. When the sewage in the sewage tank reaches a certain height, it can cut off the channel to prevent sewage from being sucked into the motor. On the other hand, the relatively high height of the sewage tank can effectively prevent excessive water vapor in the sewage tank from being sucked into the suction motor 4.

[0046] 4 , the main body 10 further includes a battery pack 52, which is disposed within the outer housing and directly in front of the cleaning liquid tank 3. Placing the battery pack 52 directly in front of the cleaning liquid tank 3 effectively shifts the center of gravity of the entire main body 10 forward, making it easier for the user to use.

[0047] Referring to Figures 6 and 7, and also to Figures 10 and 11, the base station 102 includes a charging bracket 103 and a tray 104 detachably connected to the charging bracket 103. Since the tray 104 carries the roller brush and performs self-cleaning on the roller brush, it needs to be cleaned by the user every once in a while. The detachable tray 104 is more convenient to clean. A fan 105 and a heating device 106 are provided inside the charging bracket 103. The airflow generated by the fan 105 is heated and blown to the position of the roller brush of the cleaning head 30. The roller brush can be effectively dried. The heating device is generally a PTC heating plate. In order to achieve a more stable charging structure, the charging connector 54 includes an electrode sheet 541 provided with a V-shaped contact port, and the V-shaped contact port is docked with the charging needle 107 on the base station 102. At the same time, the charging needle 107 is retractably arranged on the base station 102. In this way, when the surface cleaning device 101 is in an upright position (ie, a stop position), the V-shaped contact port can be located just above the charging needle 107 , and the charging needle 107 can be in good contact with the electrode sheet 541 under the action of elastic force.

[0048] Although the implementation scheme of the present application has been disclosed as above, it is not limited to the applications listed in the description and implementation mode. It can be fully applied to various fields suitable for the present application. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present application is not limited to the specific details and illustrations shown and described herein.
