[0002] Portable cleaning devices are gradually becoming common household cleaning tools. Among them, portable cleaning devices with roller or belt mops can achieve running water mopping. That is, when mopping, the clean water tank in the main unit supplies clean water to the mop, while the dirty water tank in the main unit collects the dirty water generated on the mop in real time. During the collection of dirty water, stains in the dirty water will stick to the walls of the dirty water tank, or after the dirty water is emptied, stains will adhere to the side walls or bottom of the dirty water tank.

[0072] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0073] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0074] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0075] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0076] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0077] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0078] This application provides a portable cleaning device, such as a sweeper or floor scrubber, commonly used in households. The portable cleaning device includes a base station, a main unit, a mop, a clean water tank 200, and a waste collection device 100. The mop, clean water tank 200, and waste collection device 100 are assembled into the main unit. The clean water tank 200 supplies clean water to the mop, while the wastewater tank 1000 collects wastewater generated on the mop in real time. During wastewater collection, stains in the wastewater will adhere to the walls of the wastewater tank 1000, or after the wastewater is drained, stains will adhere to the side walls or bottom of the wastewater tank 1000.

[0079] Therefore, refer to Figures 1 to 4 As shown, the portable cleaning device of this application is designed to connect the clean water tank 200 to the wastewater collection device 100 containing the wastewater tank 100 via a water pump 300. This connection primarily connects to the cleaning nozzles 2000 installed in the wastewater tank 1000. The water pump 300 then supplies water to the cleaning nozzles 2000 in the wastewater tank 1000, allowing the nozzles to spray cleaning water into the interior of the wastewater tank 1000, thus removing dirt from the inner wall of the wastewater tank 1000. Cleaning the inner wall of the wastewater tank 1000 by spraying eliminates the need for the user to manually remove the wastewater tank 1000 from the main unit for cleaning.

[0080] Continue reading Figures 5 to 12 As shown, the aforementioned cleaning equipment waste collection device 100 may include a wastewater tank 1000 and a cleaning nozzle 2000, with the cleaning nozzle 2000 mounted in the wastewater tank 1000. The cleaning nozzle 2000 includes a nozzle component 2100 and a connecting pipe component 2200. The nozzle component 2100 has a main channel 2110 and several branch channels 2120 internally. The input end of the main channel 2110 is connected to the output end of the connecting pipe component 2200. The input end of the connecting pipe component 2200 is configured to connect to a water source, specifically the water source of the clean water tank 200. Therefore, the input end of the connecting pipe component 2200 can be configured to connect to the clean water tank 200. Alternatively, the input end of the connecting pipe component 2200 can also be connected to other water sources, which are not limited here.

[0081] Continue reading Figure 10 and Figure 12As shown, from different angles, the main channel 2110 is connected to the input of several branch channels 2120, and the outputs of all branch channels 2120 are connected to the inner cavity of the wastewater tank 1000. Therefore, after the clean water in the clean water tank 200 is pumped to the cleaning nozzle 2000 of the wastewater tank 1000 by the water pump 300, it can be received through the connecting pipe 2200, allowing the clean water to be branched from the main channel 2110 to each branch channel 2120 at a certain speed, and then flow out from the output of each branch channel 2120. Based on the different orientations of the outputs of the branch channels 2120, the clean water can be sprayed at a certain speed into the inner cavity of the wastewater tank 1000, thereby cleaning the stains on the walls of each cavity within the wastewater tank 1000.

[0082] Continue reading Figures 1 to 3 As shown, in one embodiment, the cleaning equipment's waste collection device 100 may further include a diversion assembly 4000. The diversion assembly 4000 includes a transmission pipe 4100 and several diversion pipes 4200. The input end of the transmission pipe 4100 is configured to connect to a water source, i.e., to a clean water tank 200, for example, via a water pump 300, a water supply pipe, or other structures, to obtain clean water from the clean water tank 200. The output end of the transmission pipe 4100 is simultaneously connected to the input ends of the several diversion pipes 4200. The number of cleaning nozzles 2000 can be configured to be several, such as two, three, or even more. In this case, the output ends of the several transmission pipes 4100 can be connected one-to-one with the connecting pipes 2200 of the several cleaning nozzles 2000, thereby supplying water to different cleaning nozzles 2000 respectively.

[0083] Regarding the design of the main channel 2110 and the diversion channel 2120 in the cleaning nozzle 2000, those skilled in the art can design the channel length, channel structure, channel size, number of channels, channel trajectory, etc. of the main channel 2110 and the diversion channel 2120 according to actual needs, and no limitations are imposed here. For example, refer to Figure 10 and Figure 12 As shown, in one embodiment, the design of the main channel 2110 can be such that, from the input end to the output end of the main channel 2110, the cross-sectional area of ​​at least a portion of the channel segment of the main channel 2110 gradually decreases. The gradually decreasing cross-sectional area allows the cleaning water to increase its flow velocity when flowing through the main channel 2110, thereby enhancing the cleaning ability of the stains through the increased flow velocity.

[0084] Continue reading Figure 10 and Figure 12As shown, in one embodiment, the design of the diversion channel 2120 can be such that, from the input end to the output end of the diversion channel 2120, the cross-sectional area of ​​at least a portion of the channel segment of the diversion channel 2120 gradually increases. The gradually increasing cross-sectional area allows the cleaning water to increase the spray area of ​​the water flow when it flows through the diversion channel 2120, thereby enhancing the cleaning area of ​​the stains through the increased spray area.

[0085] For example, in one embodiment, the main channel 2110 may include a first fixed-diameter channel 2111 and a first variable-diameter channel 2112. The first fixed-diameter channel 2111 and the first variable-diameter channel 2112 are connected. The first fixed-diameter channel 2111 maintains a fixed inner diameter, and the connecting pipe 2200 can be assembled into the first fixed-diameter channel 2111 of the nozzle component 2100. In the first variable-diameter channel 2112, it can be designed so that the cross-sectional area of ​​the channel gradually decreases from the input end to the output end of the main channel 2110. This allows the cleaning water to first receive the cleaning water from the connecting pipe 2200 through the first fixed-diameter channel 2111, and then increase the water flow velocity when the cleaning water passes through the first variable-diameter channel 2112.

[0086] Meanwhile, the diversion channel 2120 may include a second fixed diameter channel 2121 and a second variable diameter channel 2122. The second fixed diameter channel 2121 maintains a fixed inner diameter and is connected between the first variable diameter channel 2112 and the second variable diameter channel 2122. In the second variable diameter channel 2122, the cross-sectional area of ​​the channel gradually increases from the input end to the output end of the diversion channel 2120, so that the clean water first receives the clean water from the main channel 2110 through the second fixed diameter channel 2121, and then increases the spray area of ​​the water flow when the clean water passes through the second variable diameter channel 2122.

[0087] Continue reading Figure 8 , 10 and Figure 12 As shown, the inner wall of the second variable diameter channel 2122 is provided with several diversion grooves 2123. Each diversion groove 2123 is arranged along the extension direction of the second variable diameter channel 2122, and the several diversion grooves 2123 are distributed circumferentially in the second variable diameter channel 2122. Therefore, each diversion groove 2123 can divert the cleaning water flowing through the second variable diameter channel 2122 to a certain extent, so that when the cleaning water is sprayed out of the second variable diameter channel 2122, it can be further dispersed, thereby increasing the cleaning area and enhancing the cleaning effect.

[0088] Furthermore, the nozzle assembly 2100 includes at least two unit components 2101, each unit component 2101 having a splicing groove. Several unit components 2101 are spliced ​​together to form the nozzle assembly 2100, and several splicing grooves of several unit components 2101 are spliced ​​together to form a main channel 2110 and several branch channels 2120. In addition, those skilled in the art can design the structure of the main channel 2110 and each branch channel 2120 through other design methods, and the structural design of each branch channel 2120 can be the same, or it can be set differently according to requirements, which is not limited here.

[0089] In one embodiment, the number of diversion channels 2120 can be configured to be several, with the output ends of the several diversion channels 2120 facing different inner walls of the sewage tank 1000. For example, the design of the diversion channels 2120 can be matched to the structure of the sewage tank 1000. In one embodiment, if the sewage tank 1000 is configured as a square box 1100, the sewage tank 1000 may have several side walls and a bottom wall. Therefore, the output ends of the several diversion channels 2120 in the cleaning nozzle 2000 can face several side walls and a bottom wall of the sewage tank 1000 respectively, so that the cleaning water sprayed from each diversion channel 2120 in the cleaning nozzle 2000 can be sprayed directly onto several side walls and a bottom wall, specifically cleaning each cavity wall of the sewage tank 1000. The spray direction can be designed to be perpendicular to each cavity wall, or it can be formed at a certain angle relative to the cavity wall.

[0090] Alternatively, in one embodiment, the cleaning nozzle 2000 is rotatably mounted on the wastewater tank 1000. The rotation can be either omnidirectional or fixed-axis rotation. Therefore, depending on the rotation method, the number and spray direction of each diversion channel 2120 of the cleaning nozzle 2000 can be specifically designed. When the cleaning nozzle 2000 is rotatably mounted on the wastewater tank 1000, when the cleaning nozzle 2000 sprays cleaning water, it can be simultaneously controlled to rotate synchronously, thereby spraying cleaning water onto each cavity wall of the wastewater tank 1000, including the side walls and bottom wall.

[0091] See Figure 5 and Figure 6 As shown, in one embodiment, the waste collection device 100 of the cleaning equipment may include a drive assembly 3000, which is mounted on the wastewater tank 1000. The drive assembly 3000 includes a driver 3100 and a transmission assembly 3200. The number of cleaning nozzles 2000 is configured to be several. The driver 3100 is driven and connected to the transmission assembly 3200, and the transmission assembly 3200 is driven and connected to several cleaning nozzles 2000. Therefore, when the driver 3100 outputs power, it can be synchronously transmitted to each cleaning nozzle 2000 through the transmission assembly 3200, thereby controlling the synchronous fixed-axis rotation of several cleaning nozzles 2000.

[0092] In one embodiment, the transmission assembly 3200 may include a drive gear 3210 and a plurality of transmission gears 3220. The drive gear 3210 is mounted on the drive shaft 3102 of the driver 3100, and the cleaning nozzle 2000 is equipped with a nozzle gear 3230. Therefore, the drive gear 3210 can be driven by the plurality of transmission gears 3220 and the nozzle gears 3230 of the plurality of cleaning nozzles 2000. When the driver 3100 outputs power, it can first control the drive gear 3210 to rotate. The drive gear 3210 can be driven by the plurality of transmission gears 3220 and the plurality of nozzle gears 3230, thereby controlling the plurality of cleaning nozzles 2000 to rotate synchronously on a fixed axis.

[0093] In this design, the diameter of several transmission gears 3220 first increases and then decreases in the direction of power transmission. This gear diameter layout allows the entire transmission assembly 3200 to achieve a large overall reduction ratio (or speed increase ratio), which typically significantly reduces output speed and increases output torque without the need for excessively large individual gears, resulting in a compact overall structural design. Furthermore, it ensures that the rotational directions of the output and input ends remain consistent.

[0094] Meanwhile, the wastewater tank 1000 has bearing holes, and the nozzle component 2100 is rotatably mounted in the bearing hole of the wastewater tank 1000 via an outer bearing 2103. The connecting pipe component 2200 is rotatably mounted in the main channel 2110 of the nozzle component 2100 via an inner bearing 2102. This allows the cleaning nozzle 2000 to rotate relative to the wastewater tank 1000, enabling it to rotate on a fixed axis under the drive of the drive assembly 3000. The inner bearing 2102 of the connecting pipe component 2200 is sealed in the main channel 2110 of the nozzle component 2100 via a sealing ring or other sealing device, and the outer bearing 2103 of the nozzle component 2100 is also sealed in the bearing hole of the wastewater tank 1000 via a sealing ring or other sealing device, thus achieving a good sealing effect.

[0095] For example, the sewage tank 1000 may include a tank body 1100, a tank cover, and a sealing plate 1200. The tank cover is fitted to the opening of the tank body 1100, and the sealing plate 1200 is also sealed to the opening of the tank body 1100 by a sealing structure such as a sealing ring, and the sealing plate 1200 is located inside the tank cover. The sealing plate 1200 has a bearing hole, and the nozzle component 2100 is rotatably fitted to the bearing hole of the sealing plate 1200 in the manner described above. At the same time, the sealing plate 1200 has a transmission hole, and the drive assembly 3000 is fitted to the sealing plate 1200, and the driver 3100 is sealed to the inside of the sealing plate 1200 by a sealing cover 3101, thereby sealing the driver 3100 in the inner cavity of the sewage tank 1000. The transmission assembly 3200 is fitted to the outside of the sealing plate 1200, and the drive shaft 3102 of the driver 3100 passes through the transmission hole and is drivenly connected to the transmission assembly 3200.

[0096] Combination Figures 1 to 12 For related structural design content of the same parts and components, please refer to the following: Figures 13 to 18 As can be seen from another embodiment, in order to improve the cleaning effect of the cleaning nozzle 2000 on the inner cavity of the sewage tank 1000, one or more cleaning nozzles 2000 can be controlled to move regularly in the inner cavity of the sewage tank 1000, such as rotating or moving. This expands the cleaning range based on the movement of the cleaning nozzles 2000 in the inner cavity of the sewage tank 1000, thereby improving the cleaning effect.

[0097] The waste collection device for cleaning equipment provided in this embodiment mainly adds a control component 5000 to the above embodiment. The control component 5000 is assembled in the wastewater tank 1000. The input end of the wastewater tank 1000 is configured to receive driving force. For example, the drive component 3000 in the above embodiment can be connected to the control component 5000 to provide driving force for the movement of the control component 5000. The output end of the control component 5000 is controlled and connected to the cleaning nozzle 2000 provided in the above embodiment. The cleaning nozzle 2000 is located in the inner cavity of the wastewater tank 1000, and the control component 5000 is configured to control the movement of the cleaning nozzle 2000 within the inner cavity of the wastewater tank 1000. Therefore, when it is necessary to clean the inner cavity of the wastewater tank 1000, water can be sprayed from the cleaning nozzle 2000. The control unit 5000 can control one or more cleaning nozzles 2000 to move in a preset manner within the cavity of the wastewater tank 1000, thereby cleaning the dirt inside the wastewater tank 1000 in all directions and improving cleaning efficiency.

[0098] In one embodiment, the control component 5000 controls the movement of the cleaning nozzle 2000 within the cavity of the wastewater tank 1000 by: controlling the cleaning nozzle 2000 to move up and down along a lifting trajectory within the cavity of the wastewater tank 1000, or controlling the cleaning nozzle 2000 to rotate along a rotation trajectory within the cavity of the wastewater tank 1000. The lifting and rotating movements can be performed separately or simultaneously, thereby adjusting the movement control method of one or more cleaning nozzles 2000 according to actual needs; no limitation is made herein.

[0099] The control method and control structure design of the control component 5000 can be specifically designed according to the movement mode of the cleaning nozzle 2000. For example, in one embodiment, the control component 5000 may include a fixed component 5100, a rotating component 5200, and a control component 5300. The fixed component 5100 is fixedly mounted to the wastewater tank 1000, and a threaded channel 5110 is formed inside the fixed component 5100. The rotating component 5200 is movably mounted to the wastewater tank 1000, and a threaded hole 5210 is formed inside the rotating component 5200. The control component 5300 is externally threaded with an external thread 5310, and a drainage channel 5320 is formed inside the control component 5300. The control component 5300 is simultaneously threadedly rotated and mounted to the threaded channel 5110 of the fixed component 5100 and the threaded hole 5210 of the rotating component 5200 via the external thread 5310. The drainage channel 5320 of the control component 5300 communicates with the cleaning nozzle 2000.

[0100] The stationary component 5100, rotating component 5200, and control component 5300 can be selected or designed as suitable component types according to requirements. For example, in one embodiment, the stationary sleeve is cylindrical with a smooth outer wall and a threaded channel 5110 machined on its inner wall. The threaded channel 5110 extends axially along the stationary sleeve, forming a continuous helical structure. The input end of the threaded channel 5110 is configured to receive a water source. This input end is designed to connect to a standard water pipe interface, ensuring that the water source can smoothly enter the threaded channel 5110. The stationary sleeve is typically made of corrosion-resistant and high-pressure-resistant materials, such as stainless steel or high-strength engineering plastics, to ensure good performance and stability during long-term use. The stationary sleeve plays a supporting and guiding role in the entire control assembly 5000, providing a motion trajectory for the rotating component 5200.

[0101] The rotating component 5200 is configured as a rotating gear with an internal threaded hole 5210. The outer circumference of the rotating gear has a toothed structure that meshes with an external drive device. The rotating gear has an internal threaded hole 5210 that matches the threaded channel 5110 of the fixed sleeve. When the rotating gear rotates, the threaded hole 5210 meshes with the threaded channel 5110 of the fixed sleeve, causing the rotating gear to move axially along the fixed sleeve. The rotating gear is configured to receive driving force, thereby controlling the control component 5300 to perform fixed-axis rotation and linear motion with reference to the central axis of the threaded channel 5110. This design enables the rotating component 5200 to achieve a precise combined motion of rotation and linear movement when receiving driving force.

[0102] Therefore, the three main parts—fixed component 5100, rotating component 5200, and control component 5300—form a complete control system. The fixed component 5100 is mounted on the sewage tank 1000 and its stability is ensured by a robust connection. The fixed component 5100 has an internal threaded channel 5110 that runs the entire length of the fixed component 5100 and has a regular internal thread structure. The diameter and pitch of the threaded channel 5110 are precisely designed to ensure accurate matching with the external thread 5310 of the control component 5300, achieving smooth rotational control. The fixed component 5100 is typically made of corrosion-resistant materials, enabling it to operate stably in sewage environments for extended periods without deformation or damage.

[0103] The rotating component 5200 is movably mounted on the sewage tank 1000 and can rotate freely on the sewage tank 1000. The rotating component 5200 has a threaded hole 5210 inside, which is coaxial with the threaded channel 5110 in the fixed component 5100 in the installed state. The threaded hole 5210 of the rotating component 5200 has an internal thread structure that matches the external thread 5310 of the control component 5300, and its pitch and diameter are consistent with the threaded channel 5110 of the fixed component 5100.

[0104] The control component 5300 has an external thread 5310, which mates with both the threaded channel 5110 of the fixed component 5100 and the threaded hole 5210 of the rotating component 5200. The control component 5300 has an internal drainage channel 5320 that extends the entire length of the control component 5300, forming a continuous fluid path. One end of the drainage channel 5320 communicates with the cleaning nozzle 2000, and the other end can be connected to a water source, allowing the cleaning fluid to flow smoothly from the water source to the cleaning nozzle 2000. The control component 5300 is simultaneously threadedly fitted into the threaded channel 5110 of the fixed component 5100 and the threaded hole 5210 of the rotating component 5200 via its external thread 5310, forming a complete threaded connection system.

[0105] When it is necessary to adjust the working state of the cleaning nozzle 2000, the drive assembly 3000 in the above embodiment can be used to drive the rotating component 5200 to rotate on a fixed axis. Since the control component 5300 is threadedly connected to both the fixed component 5100 and the rotating component 5200, the rotation of the rotating component 5200 will cause the control component 5300 to move axially within the fixed component 5100.

[0106] The entire control assembly 5000 operates based on a precision threaded transmission mechanism. When the rotating component 5200 rotates, the control component 5300 experiences axial displacement due to the threaded connection between it and the fixed component 5100. This displacement precisely controls the connection between the drainage channel 5320 and the cleaning nozzle 2000, enabling precise adjustment of the cleaning fluid flow rate, pressure, or spray direction. Simultaneously, the threaded connection provides excellent sealing performance, preventing leakage of the cleaning fluid during transmission. The control assembly 5000 features a compact design, simple operation, and easy maintenance. It provides stable and reliable control functions in various wastewater treatment equipment, effectively improving cleaning efficiency and quality.

[0107] Therefore, when it is necessary to clean the inner cavity of the sewage tank 1000, water is input through the threaded channel 5110 of the fixing component 5100. The water flows into the extension pipe 5400 through the drainage channel 5320 of the control component 5300, and is finally sprayed out from the cleaning nozzle 2000. Simultaneously, the drive component 3000 in the above embodiment can be used to provide driving force to the rotating component 5200, controlling the rotating component 5200 to rotate on a fixed axis. The rotating component 5200 drives the control component 5300 to rotate on a fixed axis with the central axis of the threaded channel 5110 as a reference, thereby causing the cleaning nozzle 2000 to rotate along a rotation trajectory within the inner cavity of the sewage tank 1000. Furthermore, while rotating, the control component 5300, due to the threaded connection with the fixing component 5100 and the rotating component 5200, can also move linearly along the central axis of the threaded channel 5110, causing the cleaning nozzle 2000 to rise and fall along a lifting trajectory within the inner cavity of the sewage tank 1000.

[0108] Therefore, through the combined rotation and lifting motion of the cleaning nozzle 2000, the dirt inside the sewage tank 1000 can be cleaned in all directions, improving cleaning efficiency.

[0109] In one embodiment, the number of cleaning nozzles 2000 is configured to be several. The flow channel 5320 of the control component 5300 includes an inlet channel 5321 and several outlet channels 5322. The input end of the inlet channel 5321 communicates with the threaded channel 5110 of the fixing component 5100, and the output end of the inlet channel 5321 communicates with the input ends of the several outlet channels 5322. The output end of each outlet channel 5322 communicates with a mating cleaning nozzle 2000. The communication between the input end of the inlet channel 5321 and the threaded channel 5110 of the fixing component 5100 forms a fluid connection path. The communication between the output end of the inlet channel 5321 and the input ends of the several outlet channels 5322 constitutes a flow distribution system. The output end of each outlet channel 5322 is connected to a matching cleaning nozzle 2000, so that fluid can be diverted from the threaded channel 5110 of the fixed component 5100 through the inlet channel 5321 and then delivered to the corresponding cleaning nozzle 2000 through each outlet channel 5322.

[0110] The cleaning nozzles 2000 are configured in multiple locations, distributed across different positions of the control unit 5300, for spraying fluid into different locations within the wastewater tank 1000. Therefore, the fluid first enters the inlet channel 5321 of the control unit 5300 through the threaded channel 5110 of the fixing component 5100, and then flows through the inlet channel 5321 to several outlet channels 5322 connected to it. Each outlet channel 5322 guides the fluid to its corresponding cleaning nozzle 2000, and finally sprays it out through the cleaning nozzle 2000. This design of the flow channel 5320 achieves rational fluid distribution, ensuring a stable fluid supply to each cleaning nozzle 2000, thereby guaranteeing the uniformity and consistency of the cleaning effect.

[0111] The cross-sectional area of ​​the inlet channel 5321 can be larger than that of a single outlet channel 5322. This design ensures pressure stability of the fluid during the diversion process. The number of outlet channels 5322 is equal to the number of cleaning nozzles 2000, forming a one-to-one correspondence. Each outlet channel 5322 is specifically responsible for supplying fluid to a particular cleaning nozzle 2000.

[0112] In one embodiment, the control component 5000 further includes a plurality of extension tubes 5400, the number of which is the same as the number of cleaning nozzles 2000. Each cleaning nozzle 2000 is connected to the output end of a matching outlet channel 5322 via an extension tube 5400. Sealing rings or other components can be used at the connection points of the extension tubes 5400 to ensure no liquid leakage. The length of the extension tubes 5400 can be adjusted according to the actual application scenario, and its diameter matches the output diameter of the outlet channel 5322 to ensure smooth fluid flow. The extension tubes 5400 are made of corrosion-resistant, high-temperature-resistant engineering plastics or stainless steel, capable of withstanding the corrosion of the cleaning liquid and a certain working pressure. Furthermore, the inner wall of the extension tubes 5400 can be made smooth to reduce resistance loss during fluid flow and improve cleaning efficiency.

[0113] In one embodiment, several extension tubes 5400 are in the same plane and have the same length. The control component 5000 controls the cleaning nozzles 2000 to rotate along a rotation trajectory in the inner cavity of the wastewater tank 1000 by controlling the control component 5300 to rotate about the central axis of the threaded channel 5110, thereby driving the several cleaning nozzles 2000 to rotate in a circular trajectory with the length of the extension tubes 5400 as the radius.

[0114] Several extension tubes 5400 are located in the same plane, and all extension tubes 5400 are of the same length. This design ensures that all cleaning nozzles 2000 move within the same plane during rotation, which facilitates uniform cleaning of the inner wall of the wastewater tank 1000 and avoids cleaning dead zones. The design of the extension tubes 5400 being of the same length ensures that all cleaning nozzles 2000 form a circular trajectory of the same radius when rotating, guaranteeing the consistency of the cleaning range.

[0115] In one embodiment, the control component 5300 reciprocates around a fixed axis within a preset angle range, where the preset angle range is less than 180°, or the control component 5300 rotates around a fixed axis within a 360° range. Therefore, the control component 5300 can operate in two different rotation modes.

[0116] The first rotation mode of the control component 5300 is reciprocating fixed-axis rotation within a preset angle range. Therefore, when the structure of the wastewater tank 1000 cannot accommodate the complete rotation of the cleaning nozzles 2000 connected by the extension pipes 5400, resulting in structural interference, the preset angle range of rotation can be less than 180°, and can be any angle value less than 180° such as 30°, 45°, 60°, 90°, 120°, or 150°. The control component 5300 can then reciprocate left and right within this angle range.

[0117] The second rotation mode of the control component 5300 is fixed-axis rotation within a 360° range. Therefore, when the structure of the wastewater tank 1000 can accommodate a complete revolution of the cleaning nozzles 2000 connected by the extension pipes 5400 without structural interference, the control component 5300 can be set to rotate a full 360° around a fixed axis, without angular limitations. The control component 5300 can rotate continuously for multiple revolutions or stop at any angular position. This is to achieve the 360° rotation function.

[0118] In one embodiment, the waste collection device of the cleaning equipment includes a sealed assembly box 5500, which is assembled inside a wastewater tank 1000. The opening of the sealed assembly box 5500 faces the inner wall of the wastewater tank 1000, and the sealed assembly box 5500 and the inner wall of the wastewater tank 1000 seal to form a sealed space 5510. The wastewater tank 1000 has a fixing hole 5520 communicating with the sealed space 5510. A fixing component 5100 penetrates the wastewater tank 1000 through the fixing hole 5520 and communicates with the sealed space 5510 of the sealed assembly box 5500. A rotating component 5200 is located in the sealed space 5510 of the sealed assembly box 5500. The sealed assembly box 5500 has a transfer hole 5530 communicating with the inner cavity of the wastewater tank 1000. A control component 5300 penetrates the sealed assembly box 5500 through the transfer hole 5530 and connects to a cleaning nozzle 2000 located in the inner cavity of the wastewater tank 1000.

[0119] The sealed assembly box 5500 can be made of waterproof material, providing excellent sealing performance and effectively preventing sewage from seeping into the sealed space 5510. The sealing assembly box 5500 has a sealing ring at its opening edge. When the sealed assembly box 5500 is installed on the inner wall of the sewage tank 1000, the sealing ring fits tightly against the inner wall of the sewage tank 1000, forming a completely sealed space and preventing sewage from entering the sealed space 5510.

[0120] A fixing hole 5520 is formed on the top wall of the sewage tank 1000. The fixing component 5100 passes through the fixing hole 5520 into the sewage tank 1000 and connects to the sealed space 5510 of the sealed assembly box 5500. The rotating component 5200 is installed inside the sealed space 5510 of the sealed assembly box 5500. Because the rotating component 5200 is located inside the sealed space 5510 and is completely isolated from sewage, it will not be damaged by sewage erosion, greatly extending the service life of the equipment.

[0121] The adapter hole 5530 on the sealed assembly box 5500 is used to connect the sealed space 5510 and the inner cavity of the wastewater tank 1000. The adapter hole 5530 may be designed with a waterproof structure. The control component 5300 passes through the adapter hole 5530, with one end connected to the rotating component 5200 in the sealed space 5510 and the other end connected to the cleaning nozzle 2000 in the inner cavity of the wastewater tank 1000.

[0122] During use, a maximum liquid level line can be defined within the cavity of the sewage tank 1000, and this maximum liquid level line is limited to be lower than that of the sealed assembly box 5500. Therefore, the sealed assembly box 5500 is kept as far as possible from being submerged in liquid. Because the sealed assembly box 5500 and the inner wall of the sewage tank 1000 form a sealed space 5510, electrical components and rotating parts 5200 are completely isolated from the sewage and will not be damaged by sewage erosion. Simultaneously, the waterproof design of the fixing component 5100 and the adapter hole 5530 ensures that the entire system will not leak during operation.

[0123] The design of this 5500 sealed assembly box solves the problem of electrical components in the cleaning equipment's waste collection device being easily damaged by moisture corrosion, thus improving the equipment's safety and service life. At the same time, the modular design of the 5500 sealed assembly box facilitates equipment maintenance and replacement, reducing maintenance costs.

[0124] Based on the structural design in the different embodiments described above, the mobile cleaning device can be configured to return to the base station after completing the cleaning task. Upon triggering the base station, the wastewater tank 1000 of the main unit begins discharging wastewater, which is then collected by the base station. After collection, the base station supplies water to the clean water tank 200 of the main unit. Simultaneously, the clean water tank 200 is connected to the cleaning nozzle 2000 of the wastewater tank 1000. When the clean water tank 200 is full or reaches a preset water level, it supplies water to the cleaning nozzle 2000 of the wastewater tank 1000, enabling active cleaning of the tank's interior. During this process, the base station also continuously supplies water to the clean water tank 200.

[0125] After the wastewater tank 1000 has been cleaning for a period of time, the clean water tank 200 can stop supplying water to the cleaning nozzles 2000 of the wastewater tank 1000, and the base station also stops supplying water to the clean water tank 200. The host can trigger the base station again, and the host's wastewater tank 1000 will start discharging wastewater. The base station collects the wastewater, thereby enabling the host's wastewater tank 1000 to complete its final cleaning.

[0126] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0127] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
