For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0034] 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 direction. 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, and the dirt recovery system is used to recover the dirt on 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.

[0035] refer to Figure 4-8 The main body 10 includes an outer housing 2 defining a receiving cavity, the receiving cavity includes a first cavity 21, and the main body 10 also includes a battery assembly 5 for providing power to the surface cleaning device 101. Figure 2 and 3, the battery assembly 5 includes a battery pack 52, a circuit board 51 and a bracket 53. Since the components such as the battery pack 52 and the circuit board 51 need to be in a dry environment to ensure their safety in use. Therefore, the sealing of the battery pack 52 and the circuit board 51 is particularly important. In order to solve the sealing problem of the battery pack 52 and the circuit board 51, the present application makes some improvements to the outer housing 2 and the battery pack 52. In one embodiment, the battery pack 52 and the circuit board 51 are welded or plugged together and fixed to the bracket 53. The first cavity 21 includes a first opening 211, and the battery pack 52 and the circuit board 51 can be loaded into the first cavity 21 from the first opening 211 after being installed on the bracket 53. The first opening 211 can be set at any position of the outer housing 2. When the battery assembly 5 is installed in the first cavity 21 as a whole, it is only necessary to seal the first opening 211. Specifically, a sealing strip is provided on the bracket 53, and 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 to improve the heat dissipation effect.

[0036] 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. In this way, since the liquid flows downward, the sealing performance can be made more reliable. 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 wires connecting the circuit board 51 and the suction motor 4, display screen and other electrical components 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 contacting the liquid here is the smallest, and basically no liquid will be contacted. A sealing structure can also be set 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 respectively located at opposite ends of the outer housing 2. Further, 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. Designing the outer housing 2 to be integrally formed can effectively reduce the installation gap and greatly improve the waterproof performance.

[0037] 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 housing 2 to accommodate the cleaning liquid tank 3 and the recovery tank 1. Figure 6 The outer housing 2 includes a side wall 24 extending in the length direction, a first opening 211 and a second opening 231 are respectively arranged at opposite ends of the side wall 24, and the side wall 24 is recessed inward to form a receiving space 241 for receiving the recovery tank 1 and / or the cleaning liquid tank 3. The battery assembly 5 is arranged in front of the receiving space along the forward direction of the surface cleaning device 101. The battery pack 52 is arranged in front of the cleaning liquid tank 3 and / or the recovery tank 1, which can effectively move the weight of the main body 10 forward, so that the user can save more effort when operating the surface cleaning device 101.

[0038] refer to Fig. 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 stopping the device first, and then lift the device and put 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, which is more convenient to take and put.

[0039] 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 direction. The main body 10 includes an outer housing 2 defining a housing cavity, and the outer housing 2 is integrally formed, and the outer housing 2 can be molded from a plastic material, or can be die-cast from a metal material. The housing cavity includes a first cavity 21 and a second cavity 23 that are interconnected, and the first cavity 21 and the second cavity 23 are distributed along the length direction 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 directions of the first opening 211 and the second opening 231 are opposite, and the first opening 211 and the second opening 231 are respectively arranged at the two ends of the outer housing 2. In this way, it is also more convenient to seal, 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 arranged at the rear side of the main body 10, that is, along the traveling direction of the surface cleaning device 101, and the recycling box 1 is arranged at a relatively rear end, and the recycling box 1 can be taken out from the storage space. The main body 10 also includes a battery assembly 5 for providing power for the surface cleaning device 101, and the battery assembly 5 is loaded 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, and the suction motor 4 is loaded into the second cavity 23 through the second opening 231.
