[0034] 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.

[0035] refer to Figure 1-8 The figure discloses a surface cleaning device 101. The surface cleaning device 101 may include a main body 10, a cleaning head 30 and a handle 20. The cleaning head 30 and the handle 20 are respectively located at both ends of the main body 10 along its length. The surface cleaning device 101 may also include a dirt recovery system and / or a cleaning liquid supply system. The cleaning liquid supply system is used to provide cleaning liquid to the surface to be cleaned or the cleaning head 30 to clean the surface to be cleaned. The dirt recovery system is used to recover dirt from the surface to be cleaned. The dirt recovery system generally includes a recovery box 1 and a suction motor 4 for generating a suction airflow. The airflow generated by the suction motor 4 can suck the dirt into the recovery box 1.

[0036] refer to Figure 4-8 The main body 10 includes an outer housing 2 defining a receiving cavity, the receiving cavity including a first cavity 21, and the main body 10 further includes a battery assembly 5 for providing power to the surface cleaning device 101. Figure 2 and 3The battery assembly 5 includes a battery pack 52, a circuit board 51, and a bracket 53. Since components such as the battery pack 52 and circuit board 51 require a dry environment to ensure their safe use, sealing the battery pack 52 and circuit board 51 is particularly important. To address the sealing issues of the battery pack 52 and circuit board 51, the present application makes certain improvements to the outer housing 2 and battery pack 52. In one embodiment, the battery pack 52 and circuit board 51 are welded or plugged together and then secured to the bracket 53. The first cavity 21 includes a first opening 211. After the battery pack 52 and circuit board 51 are installed in the bracket 53, they can be inserted into the first cavity 21 through the first opening 211. The first opening 211 can be located anywhere in the outer housing 2. Once the battery assembly 5 is fully installed in the first cavity 21, only the first opening 211 needs to be sealed. Specifically, a sealing strip is provided on the bracket 53. The sealing strip is used to contact the inner wall of the outer housing 2 to form a seal after the bracket 53 is installed in the first cavity 21. In order to enable the battery assembly 5 to dissipate heat better, at least one heat dissipation hole 531 is opened on the bracket 53. Through the heat dissipation hole 531, the circuit board 51 or the battery board can directly face the inner wall of the outer shell, thereby improving the heat dissipation effect.

[0037] refer to Figure 6-8 In one embodiment, when the main body 10 is in an upright position, the first opening 211 is arranged toward the surface to be cleaned, so that the sealing performance can be made more reliable because the liquid flows downward. The outer housing 2 also defines a second cavity 23, and the second cavity 23 is connected to the first cavity 21 through a wire hole. The lines connecting the circuit board 51 and electrical components such as the suction motor 4 and the display screen pass through the wire hole. The second cavity 23 includes a second opening 231, and the suction motor 4 of the surface cleaning device 101 is installed in the second cavity 23 through the second opening 231. The second opening 231 is preferably set to face the direction of the handle 20. In this way, since the second opening 231 is at the top of the outer housing 2, the probability of contact with the liquid here is the smallest, and basically no liquid will be contacted. A sealing structure can also be provided at the second opening 231. Of course, the second opening 231 can also be set to face other positions. Reference Figure 6-8 In this embodiment, the first opening 211 and the second opening 231 are located at opposite ends of the outer housing 2. Furthermore, the outer housing 2 is an integrally formed structure. The outer housing 2 can be molded from a plastic material or die-cast from a metal material. The integral design of the outer housing 2 effectively reduces installation gaps and significantly improves waterproof performance.

[0038] Due to the presence of the cleaning liquid tank 3 and the recovery tank 1, the main body 10 will be more or less in contact with the liquid. In order to improve the sealing performance of the main body 10 as much as possible, a receiving space 241 is formed on the side wall 24 of the integrally formed outer shell 2 to accommodate the cleaning liquid tank 3 and the recovery tank 1. Specifically, refer to Figure 6 The outer housing 2 includes a side wall 24 extending along its length. A first opening 211 and a second opening 231 are respectively provided at opposite ends of the side wall 24. The side wall 24 is recessed inward to form a receiving space 241 for accommodating the recovery tank 1 and / or the cleaning liquid tank 3. The battery pack 52 is positioned directly in front of the receiving space along the forward direction of the surface cleaning device 101. Placing the battery pack 52 directly in front of the cleaning liquid tank 3 and / or the recovery tank 1 effectively shifts the weight of the main body 10 forward, thereby reducing the user's effort when operating the surface cleaning device 101.

[0039] refer to Figure 9 The figure discloses a cleaning system, which includes a surface cleaning device 101 and a base station 102. The user can directly drive the surface cleaning device 101 into the base station 102 without having to stop the device first and then lift the device and place it into the base station 102. In this way, the recovery box 1 and the cleaning liquid tank 3 are placed behind the main body 10, making it more convenient to take and put.

[0040] refer to Figure 1-8 In one embodiment, the surface cleaning device 101 includes a main body 10, a cleaning head 30 and a handle 20, and the cleaning head 30 and the handle 20 are respectively located at the two ends of the main body 10 along its length. The main body 10 includes an outer housing 2 defining a housing cavity. The outer housing 2 is integrally formed and can be molded from a plastic material or die-cast from a metal material. The housing cavity includes a first cavity 21 and a second cavity 23 that are interconnected. The first cavity 21 and the second cavity 23 are distributed along the length of the outer housing 2. The first cavity 21 includes a first opening 211, and the second cavity 23 includes a second opening 231. The first opening 211 and the second opening 231 are in opposite directions. The first opening 211 and the second opening 231 are respectively arranged at the two ends of the outer housing 2. In this way, sealing is also more convenient and the waterproof performance is better. The side wall 24 of the outer housing 2 also defines a housing space for accommodating the recovery box 1 and / or the cleaning liquid tank 3. Specifically, the storage space is located at the rear side of the main body 10, that is, along the direction of travel of the surface cleaning device 101. The recycling bin 1 is located at a relatively rearward end and can be removed from the storage space. The main body 10 also includes a battery assembly 5 for powering the surface cleaning device 101. The battery assembly 5 is installed into the first cavity 21 through the first opening 211. The main body 10 also includes a suction motor 4 for generating a suction airflow. The suction motor 4 is installed into the second cavity 23 through the second opening 231.
