Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0020] It is understood that descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the cleaning equipment provided in the embodiments of this application.

[0023] like Figure 1 As shown, the cleaning device 10 includes a main unit 11 and a mop head 12. The main unit 11 includes a main unit bracket, a waste liquid tank and a first power unit. The main unit bracket is provided with a first placement position and a second placement position. The waste liquid tank is installed in the first placement position and the first power unit is installed in the second placement position.

[0024] Please see Figures 2 to 4 , Figure 2 This is a first three-dimensional structural diagram of the tractor provided in the embodiments of this application. Figure 3 This is a partial structural diagram of region A of the tractor provided in an embodiment of this application. Figure 4 This is a partial structural schematic diagram of the tractor sealing shell provided in an embodiment of this application.

[0025] like Figures 2 to 4 As shown, the tractor head 12 includes a tractor head body 121, a roller brush component 123, a suction component 124, a control component 125, and a sealing medium. The tractor head body 121 is provided with at least one placement chamber 122 having an opening 1221. The placement chamber 122 is provided with a mounting structure 1222 forming a mounting position for mounting the control component 125. After the control component 125 is installed in the mounting position, a first gap exists between the control component 125 and the peripheral inner wall of the placement chamber 122. The sealing medium fills the first gap and seals the opening 1221 of the placement chamber 122, thereby waterproofing and sealing the control component 125 placed in the placement chamber 122 through the cooperation of the sealing medium and the placement chamber 122.

[0026] In one embodiment, the sealing medium includes, but is not limited to, waterproof adhesive and hot melt adhesive.

[0027] The roller brush component 123 is movably connected to the tractor head body 121 and can move relative to the tractor head body 121. The roller brush component 123 includes a second power component 1231, a sealing shell 1232, and a roller brush 1233. The sealing shell 1232 forms a receiving cavity 1234. The second power component 1231 is disposed in the receiving cavity 1234, and one end of the second power component 1231 is movably connected to the tractor head body 121 so that the roller brush component 123 is movably connected to the tractor head body 121. The other end of the second power component 1231 is fixedly connected to the sealing shell 1232. The outside of the sealing shell 1232 is connected to the roller brush 1233 so that the second power component 1231 can drive the roller brush 1233 to move relative to the tractor head body 121 by driving the sealing shell 1232.

[0028] The suction component 124 is disposed on the tractor body 121. The suction component 124 is connected to the waste liquid tank through the first power component, so that the suction component 124 draws the liquid into the waste liquid tank under the drive of the first power component, thereby enabling the cleaning equipment 10 to draw the liquid through the suction component 124 of the tractor body 121.

[0029] This design enables the mop head 12 to perform cleaning and liquid absorption functions via a roller brush, and also provides a waterproof structure to waterproof and seal the control component 125 and the first power component. This waterproofs the electronic components in the mop head 12, allowing for comprehensive cleaning and rinsing of the mop head 12. This prevents the cleaning equipment 10 from having uncleaned areas that may produce odors, thus ensuring a positive user experience for consumers.

[0030] In some embodiments, the second power component 1231 disposed in the sealing shell 1232 has a fixed end 1235 and an output end 1236, and the output end 1236 is movable relative to the fixed end 1235. A transmission structure 1237 is formed in the accommodating cavity 1234 of the sealing shell 1232. The fixed end 1235 of the second power component 1231 is movably connected to the tractor body 121 so that the roller brush component 123 is movably connected to the tractor body 121. The output end 1236 of the second power component 1231 is connected to the transmission structure 1237 in the accommodating cavity 1234 of the sealing shell 1232 so as to transmit the power of the power component 1231 to the sealing shell 1232.

[0031] This configuration not only allows the tractor body 121 to seal the second power component 1231 in conjunction with the sealing shell 1232, but also allows the second power component 1231 located in the sealing shell 1232 to drive the sealing shell 1232 to move, thus ensuring both the power output of the second power component 1231 and the waterproof protection of the second power component 1231.

[0032] In some embodiments, the roller brush 1233 of the roller brush component 123 is disposed at the outer end of the sealing shell 1232 away from the receiving cavity 1234 and covers the surface of the sealing shell 1232, so that the second power component 1231 can drive the sealing shell 1232 to drive the roller brush 1233 to move, thereby enabling the roller brush component 123 to perform cleaning operations.

[0033] It is understood that the roller brush 1233 and the sealing shell 1232 have multiple connection methods. For example, the roller brush 1233 and the sealing shell 1232 have a detachable connection structure that is compatible with each other, so that the roller brush 1233 can be removed from the sealing shell 1232 and reinstalled as needed, thereby making the roller brush 1233 a convenient replacement as a cleaning consumable.

[0034] In some embodiments, the cleaning device 10 has a suction channel that connects the suction component 124 and the mop head 12. One end of the suction channel has a suction port 1241 located at the end of the mop head body 121 near the roller brush component 123. The other end of the suction channel has a waste liquid tank. A first power component is located in the suction channel or the waste liquid tank so that the cleaning device 10, driven by the first power component, draws the liquid at the suction port 1241 through the suction channel to the waste liquid tank.

[0035] This configuration allows the suction port 1241 to be close to the roller brush component 123, so that after the roller brush component 123 performs a cleaning operation and generates waste liquid, the suction port 1241 can quickly suck the generated waste liquid into the waste liquid tank, thereby helping to improve the cleaning efficiency of the roller brush component 123.

[0036] Please see Figures 5 to 6 , Figure 5 This is a first cross-sectional perspective view of the tractor unit provided in an embodiment of this application. Figure 6 This is a schematic diagram of the second three-dimensional structure of the tractor provided in the embodiments of this application.

[0037] like Figures 5 to 6 As shown, in some embodiments, the tractor head 12 further includes a drain component 127, a clean water tank 128, and a third power component 126. The clean water tank 128 is disposed in at least one of the main unit 11 and the tractor head 12. In this embodiment, the clean water tank 128 is disposed in the tractor head 12.

[0038] The drain component 127 is located at one end of the tractor body 121 near the roller brush component 123, and is connected to the clean water tank 128 through the third power component 126. The third power component 126 is used to provide power for the liquid in the clean water tank 128 to be transported through the drain component 127, so that the drain component 127 can discharge the liquid in the clean water tank 128 through the third power component 126.

[0039] The drain component 127 is also located on the side adjacent to the suction port 1241. After the drain component 127 outputs the liquid from the clean water tank 128, the roller brush component 123 works in conjunction with the liquid output by the drain component 127 to clean the water, thereby improving the cleaning efficiency of the roller brush component 123. After cleaning is completed, the suction port 1241 sucks away the waste liquid generated after cleaning, thereby ensuring the cleaning effect of the cleaning equipment 10.

[0040] In some embodiments, the draining component 127 includes a plurality of drain ports 1271 spaced apart, which are provided corresponding to the roller brush component 123, so that the plurality of drain ports 1271 can discharge liquid simultaneously and evenly, which helps to improve the draining rate and uniformity of the draining component 127.

[0041] In some embodiments, the clear water tank 128 includes a tank body 1281, a liquid filling component 1282, a first liquid outlet component 1283, and a filter component 1284. The liquid filling component 1282 and the filter component 1284 are both disposed in the tank body 1281. The liquid filling component 1282 is connected to the outside to deliver liquid to the tank body 1281, thereby replenishing the liquid in the clear water tank 128 from the outside. One end of the first liquid outlet component 1283 is connected to the filter component 1284, and the other end is connected to the third power component 126. Under the action of the third power component 126, the liquid in the clear water tank 128 is filtered by the filter component 1284 and then delivered to the drain component 127 via the connected first liquid outlet component 1283.

[0042] This configuration allows the cleaning device 10 to continuously output liquid through the clean water tank 128 during the cleaning process, ensuring the continuity of the cleaning process. Furthermore, the liquid in the tank 1281 is filtered by the filter component 1284 installed inside the tank 1281 and then transported to the drain component 127 through the first liquid outlet component 1283. The filtered liquid is then used for cleaning, greatly improving the cleaning effect of the cleaning device 10.

[0043] Please see Figure 7 , Figure 7 This is a second cross-sectional perspective view of the tractor provided in the embodiments of this application.

[0044] like Figure 7 As shown, in some embodiments, the clear water tank 128 further includes a second liquid outlet assembly 1285. The second liquid outlet assembly 1285 includes a liquid outlet 1286 and a switch 1287. The liquid outlet 1286 is connected to the tank body 1281, and the switch 1287 has a first state and a second state. In the first state, the switch 1287 cooperates with the liquid outlet 1286 to isolate the tank body 1281 from the outside, so that liquid can be stored in the tank body 1281. In the second state, the switch 1287 is away from the liquid outlet 1286 so that the tank body 1281 is connected to the outside through the liquid outlet 1286.

[0045] In one embodiment, the switch 1287 is rotatable, allowing the switch 1287 to switch between a first state and a second state by rotating.

[0046] This design allows the water tank 128 to quickly discharge liquid through the outlet 1286 after the cleaning device 10 has finished cleaning and there is still liquid residue in the water tank 128, thereby preventing the residual liquid in the water tank 128 from developing an odor after being left for a long time.

[0047] In some embodiments, the second liquid dispensing assembly 1285 further includes a one-way guide 1288, which is disposed on the switch 1287. The one-way guide 1288 allows liquid to be introduced into the clear water tank 128 from the outside. This allows liquid to be manually introduced into the clear water tank 128 through the one-way guide 1288 when the switch 1287 isolates the tank 1281 from the outside in the first state, and prevents liquid in the clear water tank 128 from leaking out of the clear water tank 128 through the one-way guide 1288.

[0048] In one embodiment, the one-way guide 1288 can be a duckbill valve. While conveying liquid to the clear water tank 128 through the one-way guide 1288, the duckbill valve can also balance the air pressure in the clear water tank 128 during the liquid change process, which helps the liquid discharge process of the clear water tank 128.

[0049] This configuration allows the water tank 128 to have a second liquid filling method in addition to the liquid filling component 1282, thus enabling the water tank 128 to have more diverse liquid replenishment methods and meet more diversified usage needs.

[0050] Please see Figure 8 , Figure 8 This is a three-dimensional structural diagram of the cleaning system provided in the embodiments of this application.

[0051] like Figure 8 As shown, this utility model also proposes a cleaning system, including the cleaning device 10 and base station 20 of any of the above embodiments.

[0052] The base station 20 includes a cleaning pool and an infusion device. When the cleaning equipment 10 is placed in the base station 20, the tractor head 12 is at least partially contained in the cleaning pool. The tractor head 12 of the cleaning equipment 10 is cleaned by the cleaning pool. The infusion device can also be used in conjunction with the liquid filling component 1282 to replenish the clean water tank 128.

[0053] Furthermore, the depth of the cleaning pool formed by the base station 20 is greater than the height of the tractor head 12. Combined with the waterproof measures of electronic components such as the control component 125 and the second power component 1231 in the tractor head 12, the tractor head 12 can be completely immersed in the liquid in the cleaning pool for cleaning, thereby enabling the base station 20 to clean the tractor head 12 in all aspects.
