[0002] Cleaning equipment, such as cleaning robots, is a widely used household cleaning device capable of autonomously cleaning surfaces without manual operation. Related technologies typically include a wastewater tank and a clean water tank on portable cleaning devices with self-cleaning functions. The clean water tank stores clean water, while the wastewater tank stores recycled wastewater. However, due to the high degree of functional integration in portable cleaning devices, and the large space occupied by the wastewater and clean water tanks, the internal space of these devices is not fully utilized.

[0041] Please see Figures 1 to 9As shown, this application embodiment provides a water tank structure 10 for a portable cleaning device and a portable cleaning device 1 including the water tank structure 10. The portable cleaning device 1 in this application embodiment can be a portable host of cleaning equipment such as a cleaning robot or floor scrubber, but is not limited to this. The portable cleaning device 1 can move on the surface to be cleaned and is used to clean contaminants on the ground surface. Specifically, in this application embodiment, the portable cleaning device 1 includes a water tank structure 10 and a housing, with the water tank structure 10 disposed within the housing. Of course, the portable cleaning device 1 may also include conventional components of existing cleaning robots such as wheels and batteries. The portable cleaning device 1 in this application embodiment integrates a first chamber 102 and a second chamber 103 for storing wastewater and clean water respectively using the water tank structure 10, which reduces space occupation. Furthermore, during the mobile cleaning process, the volumes of the first chamber 102 and the second chamber 103 can be automatically adjusted according to the cleaning progress, making full use of the internal space of the water tank structure 10, which is beneficial to improving the internal space utilization rate of the portable cleaning device 1 and enhancing the product competitiveness of the portable cleaning device 1.

[0042] See Figures 2 to 9 As shown, the water tank structure 10 for the portable cleaning equipment includes a water tank shell 100 and an isolation mechanism 200. The water tank shell 100 is an integral structure with a certain strength, and its interior forms a receiving cavity 101. For example, the receiving cavity 101 can be set in a rectangular, cylindrical, or other shape to adapt to the internal space installation requirements of the portable cleaning equipment 1. The isolation mechanism 200 is disposed within the receiving cavity 101. The overall structure of the isolation mechanism 200 must be adapted to the cross-sectional shape of the receiving cavity 101, thereby dividing the receiving cavity 101 into two independent chambers, a first chamber 102 and a second chamber 103. The first chamber 102 and the second chamber 103 are located on opposite sides of the isolation mechanism 200, and the first chamber 102 and the second chamber 103 are not connected to each other, so that the first chamber 102 and the second chamber 103 can be used to store wastewater and clean water respectively, so as to collect wastewater generated during the cleaning process and provide clean water. At least a portion of the isolation mechanism 200 is movably connected to the inner wall of the receiving cavity 101, allowing at least a portion of the isolation mechanism 200 to move within the receiving cavity 101 to adjust the volume of the first chamber 102 and the second chamber 103. For example, by means of sliding fit, at least a portion of the isolation mechanism 200 can move along a preset trajectory within the receiving cavity 101, thereby changing the position of the isolation mechanism 200 itself within the receiving cavity 101, and thus adjusting the volume of the first chamber 102 and the second chamber 103 located on both sides of the isolation mechanism 200.

[0043] Through the above structural design, the water tank structure 10 in this embodiment can use the first chamber 102 and the second chamber 103 to store sewage and clean water respectively. That is, the first chamber 102 serves as the sewage chamber, and the second chamber 103 serves as the clean water chamber, thereby integrating the sewage chamber and the clean water chamber within the water tank shell 100. Compared to the method of setting up separate clean water tanks and sewage tanks, the water tank structure 10 in this embodiment can eliminate the space and redundant structure between two independent water tanks, resulting in a more compact structure and improving the space utilization rate inside the portable cleaning device 1. Furthermore, the volume of the first chamber 102 and the second chamber 103 can be adjusted through the isolation mechanism 200, thereby adapting to the water demand of the portable cleaning device 1 at different working stages. For example, in the initial cleaning stage, clean water consumption is rapid and wastewater volume is low. When the second chamber 103 is filled with clean water, the isolation mechanism 200 moves towards the first chamber 102. At this time, the volume of the second chamber 103 increases, and the volume of the first chamber 102 decreases, occupying the wastewater storage space to store clean water. After a period of cleaning, the wastewater volume increases and the clean water volume decreases. As the movable cleaning equipment 1 consumes clean water during the cleaning process, the isolation mechanism 200 moves towards the second chamber 103. At this time, the volume of the second chamber 103 decreases, and the volume of the first chamber 102 increases, thereby gradually releasing the space occupied by the wastewater, and the gradually recovered wastewater begins to flow back into the first chamber 102. As the wastewater in the first chamber 102 gradually increases, the isolation mechanism 200 continues to move towards the second chamber 103, gradually encroaching on the space occupied by the clean water. As a result, as the clean water is gradually consumed and the wastewater is gradually recycled, the volume of the first chamber 102 and the second chamber 103 will be adaptively adjusted to optimize the space utilization, while the total volume of the water tank structure 10 remains unchanged, which helps to save the internal space of the portable cleaning equipment 1.

[0044] Further, see Figure 2 and Figure 3As shown, in some embodiments, the isolation mechanism 200 includes a movable member 210 and an isolation member 220. At least a portion of the structure of the movable member 210 is movably connected to the inner wall of the receiving cavity 101, such that when the movable member 210 is subjected to an external force, at least a portion of the structure of the movable member 210 can move relative to the inner wall of the receiving cavity 101 under the action of the external force. The isolation member 220 is connected to the inner wall of the receiving cavity 101 through the movable member 210, and the isolation member 220 cooperates with the movable member 210 to divide the receiving cavity 101 into a first chamber 102 and a second chamber 103. Therefore, when at least a portion of the structure of the movable member 210 moves inside the receiving cavity 101, it will simultaneously drive the isolation member 220 to move inside the receiving cavity 101, so that the isolation mechanism 200 as a whole moves inside the receiving cavity 101, thereby stably dividing the receiving cavity 101 into a first chamber 102 and a second chamber 103, and maintaining the independence of the first chamber 102 and the second chamber 103 throughout the separation process, avoiding the situation where the first chamber 102 and the second chamber 103 are interconnected.

[0045] Optionally, see Figure 3 As shown, in some embodiments, the movable member 210 is arranged around the outer periphery of the spacer 220. For example, the movable member 210 can be configured as a rectangular frame, annular frame, or other frame structure. The movable member 210 is fitted onto the edge of the spacer 220, ensuring that the movable member 210 and the spacer 220 form a stable whole. At least a portion of the outer edge of the movable member 210 is made of a flexible material, such as flexible rubber or elastic silicone, giving the at least a portion of the outer edge of the movable member 210 a certain degree of elasticity and sealing. The at least a portion of the outer edge of the movable member 210, made of flexible material, contacts the inner wall of the receiving cavity 101. The flexible material ensures that the movable member 210 is in close contact with the inner wall of the receiving cavity 101, thereby ensuring sealing. Specifically, the movable component 210 is configured to move relative to the inner wall of the receiving cavity 101 under the action of external force. At this time, the flexible outer edge of the movable component 210 can adapt to the movement of the movable component 210, ensuring that the flexible outer edge always fits the inner wall of the receiving cavity 101, avoiding gaps between the outer edge of the movable component 210 and the inner wall of the receiving cavity 101, realizing dynamic sealing between the movable component 210 and the inner wall of the receiving cavity 101, thereby ensuring that the isolation mechanism 200 effectively isolates and separates the first chamber 102 and the second chamber 103, preventing sewage and clean water from communicating with each other.

[0046] Optionally, in some embodiments, the separator 220 includes a separator membrane. This separator membrane is a thin, flexible structure; for example, it can be made of polyamide film, polyethylene composite film, etc., giving the separator 220 certain properties such as water resistance, tensile strength, and aging resistance, ensuring that the separator 220 is not easily corroded or damaged after long-term contact with water. Furthermore, the flexible separator membrane is lightweight, reducing the load on the movable part 210 when it drives the separator 220, reducing the driving force required for the isolation mechanism 200 to move, and making the isolation mechanism 200 easier to move, thus allowing for more sensitive adjustment of the volume of the first chamber 102 and the second chamber 103.

[0047] It should be understood that in other alternative embodiments, the isolation member 220 may also be made of a rigid material, such as a plastic plate or a metal plate, so that the isolation member 220 has a certain rigidity and is not easily damaged or deformed by water pressure.

[0048] Further, see Figure 4 As shown, in some embodiments, the isolation mechanism 200 further includes a guide member 230, which is disposed within the receiving cavity 101 and fixed to the water tank shell 100. The movable member 210 or the isolation member 220 is slidably connected to the guide member 230. For example, the guide member 230 can be configured as a long, cylindrical rod structure, with its extension direction parallel to the movement direction of the isolation mechanism 200. Specifically, the guide member 230 passes through both the first chamber 102 and the second chamber 103, and both ends of the guide member 230 are connected to the inner wall of the water tank shell 100 by bolts, snap fasteners, or other means. A guide hole 211 is provided on the movable member 210, and the guide member 230 passes through the guide hole 211, allowing the movable member 210 to slide along the extension direction of the guide rod. Furthermore, a sealing ring or sealing layer can be installed on the inner wall of the guide hole 211 to ensure a seal between the outer wall of the guide rod and the inner wall of the guide hole 211, preventing the first chamber 102 and the second chamber 103 from communicating with each other. The addition of the guide member 230 solves the problem of "the isolation mechanism 200 is prone to deviation during movement": thus, through the limiting effect of the guide member 230, the isolation mechanism 200 can only move in a preset direction, improving the stability and smoothness of the movement of the isolation mechanism 200, and ensuring that the isolation mechanism 200 can effectively separate the first chamber 102 and the second chamber 103. In addition, the guide member 230 can also distribute the force on the isolation mechanism 200 during movement, avoiding damage caused by local stress concentration, which helps to extend the service life of the isolation mechanism 200 and ensure the long-term stable operation of the water tank structure 10.

[0049] It should be noted that the driving force for the isolation mechanism 200 to move within the receiving cavity 101 can come from the liquid pressure difference between the first chamber 102 and the second chamber 103. For example, when the liquid level in the first chamber 102 is higher than the liquid level in the second chamber 103, the isolation mechanism 200 will be pushed towards the second chamber 103 under the action of the pressure difference; when the liquid level in the first chamber 102 is lower than the liquid level in the second chamber 103, the isolation mechanism 200 will be pushed towards the first chamber 102 under the action of the pressure difference, thereby adjusting the volume of the first chamber 102 and the second chamber 103.

[0050] Of course, the driving force for the isolation mechanism 200 to move within the receiving cavity 101 can also come from a separate driving source. Specifically, in some embodiments, see [reference needed]. Figure 4 As shown, the isolation mechanism 200 also includes a drive component 240, which may be an electric actuator, cylinder, or other similar device. The drive component 240 is disposed within the receiving cavity 101 and fixed to the water tank housing 100. The drive component 240 is driven to either the movable component 210 or the isolation component 220. For example, when the drive component 240 is an electric actuator, the actuator end is fixedly connected to the movable component 210. The actuator is extended or retracted by a motor, causing the movable component 210 to move, thereby driving the isolation mechanism 200 to move. Furthermore, the drive component 240 can be electrically connected to the control system of the portable cleaning equipment 1 to automatically control the movement of the isolation mechanism 200 according to the operating status of the portable cleaning equipment 1, thereby intelligently adjusting the volume of the first chamber 102 and the second chamber 103. In this embodiment, the drive component 240 can actively drive the isolation mechanism 200 to adjust the volume of the first chamber 102 and the second chamber 103, avoiding problems such as insufficient clean water or sewage overflow caused by untimely volume adjustment. Moreover, the drive component 240 can be linked with the overall control logic of the portable cleaning device 1 to optimize the user experience of the portable cleaning device 1.

[0051] Further, see Figures 2 to 9As shown, in some embodiments, the volume of the second chamber 103 is larger than the volume of the first chamber 102. The second chamber 103 is used to store clean water, while the first chamber 102 is used to store wastewater. Specifically, during cleaning operations, the second chamber 103 is used to spray clean water onto the cloth or the surface to be cleaned to keep the cloth moist and improve cleaning efficiency. Simultaneously, the movable cleaning device 1 scrapes and collects wastewater from the soiled cloth into the first chamber 102, or collects wastewater from the surface to be cleaned into the first chamber 102. Since the amount of clean water consumed is generally greater than the amount of wastewater collected, this embodiment controls the volume of the second chamber 103 (for storing clean water) to be larger than the volume of the first chamber 102 (for storing wastewater) to meet the clean water usage requirements and ensure that frequent water replenishment is not required for each cleaning cycle. For example, the ratio of the volume of the second chamber 103 to the volume of the first chamber 102 can be in the range of 3:1 to 3:2.5. Therefore, the larger volume of the second chamber 103 can meet the high demand for clean water, extend the runtime of a single cleaning cycle, and reduce the frequency of water refills by users. At the same time, since the first chamber 102 does not need to store wastewater in the early stages of cleaning, controlling the smaller volume of the first chamber 102 can avoid the problem of long-term empty space wastage of the first chamber 102, further optimizing the space utilization of the water tank structure 10.

[0052] Further, see Figure 4 As shown, in some embodiments, the water tank structure 10 further includes a limiting member 300. Specifically, the limiting member 300 is disposed within the receiving cavity 101 and fixed to the water tank shell 100. The limiting member 300 is used to block the isolation mechanism 200 so that the volume of the first chamber 102 located on one side of the isolation mechanism 200 is greater than the volume of the second chamber 103 located on the other side of the isolation mechanism 200. For example, the limiting member 300 can be configured as a block, baffle, boss, or other structure protruding from the inner wall of the receiving cavity 101, as long as it can block the isolation mechanism 200. Furthermore, the limiting member 300 is positioned on the path of the isolation mechanism 200 moving toward the second chamber 103. That is, when the isolation mechanism 200 moves toward the second chamber 103, it will be blocked by the limiting member 300, preventing the isolation mechanism 200 from continuing to compress the volume of the second chamber 103. This ensures that the volume of the second chamber 103 is greater than the volume of the first chamber 102, avoiding insufficient clean water in the second chamber 103 due to over-compression, which would affect the cleaning work.

[0053] Furthermore, in some embodiments, the isolation mechanism 200 is arranged linearly or obliquely along the height, width, or length direction of the water tank shell 100. Specifically, the water tank shell 100 has a generally cuboid structure, and the isolation mechanism 200 has a generally flat structure. The isolation mechanism 200 can be arranged along the height, width, or length direction of the water tank shell 100, and its arrangement can be linear or oblique. For example, see... Figure 5As shown, when the isolation mechanism 200 is arranged in a straight line along the height direction, the isolation mechanism 200 is parallel to the vertical direction and moves in the horizontal direction, thereby separating the left and right chambers in the horizontal direction to accommodate the wider movable cleaning device 1. Also, for example, see [reference needed]. Figure 6 As shown, when the isolation mechanism 200 is inclinedly disposed in the receiving cavity 101, that is, when the isolation mechanism 200 is at a certain angle to the horizontal or vertical plane, the isolation mechanism 200 can adapt to the irregular space inside the receiving cavity 101, such as the corner area or the arc area, thereby effectively separating the receiving cavity 101.

[0054] Further, see Figure 7 As shown, in some embodiments, a filter element 400 is provided in the first chamber 102. For example, the filter element 400 can be a filter screen, filter membrane, or other structural forms. The filter element 400 is positioned between the inlet and outlet of the first chamber 102. Therefore, after sewage enters the first chamber 102 from the inlet, it must first flow through the filter element 400 before flowing to the outlet. Thus, the filter element 400 can filter solid dirt such as hair and dust from the sewage, preventing dirt from clogging the outlet of the first chamber 102 and facilitating regular cleaning, ensuring the long-term stable operation of the first chamber 102 and extending the service life of the water tank structure 10.

[0055] To facilitate cleaning of accumulated dirt in the first chamber 102, the receiving chamber 101 can be configured as an open structure. For details, see [link to relevant documentation]. Figures 8 to 9 As shown, in some embodiments, the water tank housing 100 includes a main housing 110 and a cover 120. The main housing 110 is the main frame of the water tank housing 100, and has a receiving cavity 101 inside. The main housing 110 has an opening 111 communicating with the receiving cavity 101, making the receiving cavity 101 an open structure. The cover 120 is connected to the main housing 110 and is used to block or open the opening 111. Specifically, the cover 120 and the main housing 110 are connected in an openable or detachable manner, for example, by means of hinge connection, bolt connection, etc., to achieve the blocking or opening of the opening 111. When the cover 120 blocks the opening 111, the cover 120 fits tightly with the edge of the main housing 110 to ensure the sealing of the receiving cavity 101 and prevent water leakage; when the cover 120 opens the opening 111, the user can perform operations such as emptying sewage and cleaning dirt. The isolation mechanism 200 is connected to the inner wall of the receiving cavity 101 of the main housing 110. When the isolation mechanism 200 divides the receiving cavity 101 into a first chamber 102 and a second chamber 103, the opening 111 of the main housing 110 communicates with the first chamber 102. Thus, after opening the cover 120, the user can directly clean the dirt accumulated in the first chamber 102, as well as perform operations such as sewage cleaning and filter replacement 400, making cleaning and maintenance operations more convenient.

[0056] Optionally, see Figure 8 As shown, in some embodiments, the top of the main housing 110 is provided with an opening 111, which connects to both the first chamber 102 and the second chamber 103. When the cover 120 is opened, both the first chamber 102 and the second chamber 103 are open structures to facilitate operations such as adding clean water, emptying wastewater, and cleaning dirt. The top of the movable part 210 is made of a flexible material, such as elastic rubber or silicone. When the cover 120 blocks the opening 111, the top of the movable part 210 contacts the cover 120. At this time, one side of the isolation mechanism 200, together with the main housing 110 and the cover 120, forms the first chamber 102, and the other side of the isolation mechanism 200, together with the main housing 110 and the cover 120, forms the second chamber 103. Because the cap 120 exerts pressure on the flexible material at the top of the movable part 210, causing the flexible material to deform, the top of the movable part 210 can tightly fit against the inner surface of the cap 120, which helps to ensure sealing and prevents the first chamber 102 and the second chamber 103 from communicating with each other. Furthermore, after opening the cap 120, the user can use the same opening 111 to empty wastewater from the first chamber 102, clean the filter element 400, and add clean water to the second chamber 103, making it convenient to use.

[0057] Optionally, see Figure 9 As shown, in some embodiments, the top of the main housing 110 has an opening 111, which connects only to the first chamber 102. The top of the movable member 210 is fixedly connected to the main housing 110, for example by welding, so that the top of the movable member 210 cannot move. At the same time, the bottom and sides of the movable member 210 are movable relative to the inner wall of the receiving cavity 101. For example, the bottom and side edges of the movable member 210 can be made of flexible material, so that the movable member 210 is in close contact with the inner wall of the receiving cavity 101, and the movable member 210 can move relative to the inner wall of the receiving cavity 101 under the action of external force. When the cover 120 blocks the opening 111, one side of the isolation mechanism 200, together with the main housing 110 and the cover 120, forms the first chamber 102, and the other side of the isolation mechanism 200, together with the main housing 110, forms the second chamber 103. Since the opening 111 at the top of the main housing 110 is only located in the upper area of ​​the first chamber 102, it can meet the maintenance needs of the first chamber 102. Furthermore, since the opening 111 is not connected to the second chamber 103, meaning the top of the second chamber 103 is structurally sealed by the main housing 110, the second chamber 103 can be replenished and discharged with clean water through pre-set inlets and outlets. This effectively protects the clean water in the second chamber 103 from external dust and impurities, ensuring water cleanliness and preventing a decrease in cleaning effectiveness due to water contamination during the cleaning process.

[0058] 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.

[0059] 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.
