Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0037] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0039] Automatic cleaning equipment belongs to the category of intelligent mobile cleaning products. During operation, automatic cleaning equipment can move across a work surface and automatically clean the areas it passes through. In related technologies, automatic cleaning equipment can be window cleaning robots, which can be used to clean surfaces and simultaneously collect wastewater during the cleaning process. Existing window cleaning robots generally adopt a full-section negative pressure suction design, with multiple suction ports for wastewater collection distributed in a dispersed manner. When the window cleaning robot operates on a vertical or inclined work surface, such as windows or curtain walls, the wastewater on the work surface will flow downwards under gravity and collect on the lower side of the window cleaning robot. This results in at least some suction ports being idle. Since the idle suction ports share a power source with the active suction ports, it severely affects the wastewater collection effect and efficiency of the window cleaning robot.

[0040] To address the aforementioned issues, this application provides a cleaning unit and cleaning equipment. By improving the structure of the wastewater recycling module, it enables it to operate in different modes, thereby enhancing the wastewater recycling effect and efficiency.

[0041] Please refer to Figure 1 and Figure 2 The first aspect of this application provides a cleaning unit 100, which is applied in a cleaning device 1000 for cleaning surfaces. The cleaning device 1000 includes, but is not limited to, a robotic vacuum cleaner, a window cleaning robot, etc. The surface can be a window surface, a curtain wall surface, a wall surface, etc., wherein the wall surface can be a tiled wall surface; the surface can be a vertical surface, an inclined surface, or a horizontal surface.

[0042] Please refer to Figure 3 , Figure 4 and Figure 5 The cleaning unit 100 provided in this embodiment includes a base 1, a first valve 21a, a second valve 21b, and a cleaning component 3. The base 1 extends along its extending direction (e.g., ...). Figure 3 The base 1 (in the direction shown by X) has a first end 1a and a second end 1b. The base 1 includes a first drain channel 11 and a second drain channel 12. The first suction port 111 of the first drain channel 11 is near the first end 1a, and the second suction port 121 of the second drain channel 12 is near the second end 1b. A first valve 21a is located in the first drain channel 11, and a second valve 21b is located in the second drain channel 12. A cleaning component 3 is mounted on the base 1. Specifically, when the first end 1a is higher than the second end 1b, the first valve 21a is closed, the first drain channel 11 is blocked, the second valve 21b is open, and the second drain channel 12 is open; when the second end 1b is higher than the first end 1a, the first valve 21a is open, the first drain channel 11 is open, the second valve 21b is closed, and the second drain channel 12 is blocked.

[0043] The base 1 is the main structure of the cleaning unit 100, providing a mounting base for components such as the first valve 21a, the second valve 21b, and the cleaning component 3. The base 1 can have various structures, such as a flat plate, a frame, or a split structure; it can also be made of various materials, such as plastic, metal, or other composite materials. The extension direction of the base 1 can be the width direction of the cleaning equipment 1000, that is, a direction perpendicular to the travel direction of the cleaning equipment 1000.

[0044] The first sewage discharge channel 11 and the second sewage discharge channel 12 are the suction structures of the cleaning unit 100, used to collect sewage on the working surface and achieve centralized discharge of sewage. The sewage includes sewage already present on the working surface and sewage generated during the cleaning process. The first sewage discharge channel 11 has a first suction port 111, which can be one, two or more. The first suction port 111 is located near the first end 1a of the base 1 and can be used to collect sewage that gathers near the first end 1a of the base 1. The second sewage discharge channel 12 has a second suction port 121, which can be one, two or more. The second suction port 121 is located near the second end 1b of the base 1 and can be used to collect sewage that gathers near the second end 1b of the base 1.

[0045] It should be noted that the first sewage discharge channel 11 and the second sewage discharge channel 12 also have sewage discharge outlets 13. The sewage discharge outlets 13 can be used to connect external sewage suction equipment and sewage storage structure, and to discharge the sewage collected by the sewage suction outlet. The external sewage suction equipment can be a sewage suction pump, such as a vacuum pump, and the sewage storage structure can be a sewage tank, etc.

[0046] It should be noted that the first sewage channel 11 and the second sewage channel 12 may have a common sewage outlet 13 or different sewage outlets 13.

[0047] The first valve 21a and the second valve 21b are switch structures located in the sewage discharge channels. The first valve 21a and the second valve 21b are respectively connected to the first sewage discharge channel 11 and the second sewage discharge channel 12, and can be used independently to control the opening and closing of the two sewage discharge channels respectively. When the first valve 21a is open, the first sewage discharge channel 11 is in a conductive state, and sewage through the first suction port 111 can flow to the sewage discharge port 13; when the first valve 21a is closed, the first sewage discharge channel 11 is in a closed state, and sewage through the first suction port 111 cannot flow to the sewage discharge port 13. When the second valve 21b is open, the second sewage discharge channel 12 is in a conductive state, and sewage through the second suction port 121 can flow to the sewage discharge port 13; when the second valve 21b is closed, the first sewage discharge channel 11 is in a closed state, and sewage through the second suction port 121 cannot flow to the sewage discharge port 13.

[0048] Understandably, since the discharge ports 13 of the first discharge channel 11 and the second discharge channel 12 are connected to the same suction pump, the two discharge channels need to share a power source, such as sharing the same vacuum pump. In this way, when one discharge channel is in the closed state and the other discharge channel is in the open state, it can be ensured that the suction force is concentrated on the open discharge channel, thereby helping to improve the suction force and suction efficiency of the discharge channel.

[0049] The cleaning component 3 is a cleaning structure in the cleaning unit 100. The cleaning component 3 is used to directly contact the work surface and perform cleaning operations. The cleaning component 3 can be of various types, such as a scraper, a cleaning brush 33, a cleaning cloth, etc. The cleaning component 3 can be fixed to the base 1 by means of adhesive, snap-fit ​​connection, etc., and is set along the extension direction of the base 1.

[0050] As an example, the cleaning unit 100 described above can be applied to a window cleaning robot and can be used to clean windows. During the cleaning process, the cleaning component 3 directly contacts and presses against the window surface, and as the cleaning unit 100 moves on the window surface, wastewater accumulates near the cleaning component 3. If the height of the first end 1a and the second end 1b of the base 1 are the same, the sewage will collect at various locations between the first end 1a and the second end 1b of the base 1. At this time, the first valve 21a and the second valve 21b are opened simultaneously, and both the first sewage channel 11 and the second sewage channel 12 are in a conductive state, allowing both sewage channels to pump sewage simultaneously. If the height of the first end 1a of the base 1 is higher than the height of the second end 1b, the sewage will collect near the second end 1b of the base 1. At this time, the first valve 21a is closed, the first sewage channel 11 is in a closed state, the second valve 21b is open, and the second sewage channel 12 is in a conductive state, allowing sewage to be pumped using only the second sewage channel 12. If the height of the second end 1b of the base 1 is higher than the height of the first end 1a, the sewage will collect near the first end 1a of the base 1. At this time, the first valve 21a is open, the first sewage channel 11 is in a conductive state, the second valve 21b is closed, and the second sewage channel 12 is in a closed state, allowing sewage to be pumped using only the first sewage channel 11.

[0051] The cleaning unit 100 provided in this application embodiment, by setting a first sewage discharge channel 11 and a second sewage discharge channel 12, with the suction ports of the two sewage discharge channels respectively located close to the first end 1a and the second end 1b of the base 1, can ensure that the suction ports have a large coverage area, thereby enabling the recovery of sewage collected in various areas. By setting a first valve 21a in the first sewage discharge channel 11 and a second valve 21b in the second sewage discharge channel 12, the first valve 21a and the second valve 21b can be used to independently control the opening or closing of the first sewage discharge channel 11 and the second sewage discharge channel 12, so that the cleaning unit 100 can selectively open the first sewage discharge channel 11 and the second sewage discharge channel 12 and recover sewage collected in specific areas according to the specific usage status and sewage collection situation, thereby improving the sewage recovery effect and sewage recovery efficiency of the cleaning unit 100.

[0052] In some embodiments, please refer to Figure 6 , Figure 7 and Figure 8 The first valve 21a and the second valve 21b are gravity-type check valves. The gravity-type check valve includes a valve body 211 and a valve core 212. The valve core 212 is movably disposed between the outlet end 2111 and the inlet end 2112 of the valve body 211. When the valve core 212 abuts against the outlet end 2111 of the valve body 211, the gravity-type check valve is closed. When the valve core 212 leaves the outlet end 2111 of the valve body 211, the gravity-type check valve is opened.

[0053] A gravity-type check valve is a type of valve that relies on gravity to achieve "one-way passage and reverse shut-off". Specifically, the valve core 212 can move within the valve body 211 under the action of gravity, thereby realizing the opening and closing of the valve.

[0054] The gravity-type check valve switches between open and closed states under the action of gravity, which can accurately adapt to the dynamic cleaning scenarios of the cleaning unit 100 and achieve automatic response without the need for additional external power components such as motors and electromagnets for driving. The structure is simple and reliable.

[0055] In some embodiments, please refer to Figure 10 The outlet end 2111 of the first valve 21a faces the second end 1b, the inlet end 2112 of the first valve 21a faces the first end 1a, the outlet end 2111 of the second valve 21b faces the first end 1a, and the inlet end 2112 of the second valve 21b faces the second end 1b.

[0056] For vertical or inclined surfaces, sewage on the working surface will flow downwards under the action of gravity. Therefore, when using the cleaning unit 100, the sewage channel on the lower side should be open and the corresponding valve should be open, while the sewage channel on the upper side should be closed and the corresponding valve should be closed. For gravity-type check valves, the valve core 212 will move downwards under the action of gravity. Therefore, when assembling the gravity-type check valve, the valve on the lower side should be able to remain open when its valve core 212 moves downwards, while the valve on the upper side should be able to remain closed when its valve core 212 moves downwards. Based on the structure of the gravity-type check valve and the arrangement of the suction port in the embodiment of this application, that is to say, in the extension direction of the base 1, the inlet end 2112 of the valve should be closer to the edge of the end where the corresponding suction port is located, while the outlet end 2111 of the valve should be closer to the middle position. In the above embodiment, the first suction port 111 is located near the first end 1a, so that the inlet end 2112 of the first valve 21a can be directed toward the first end 1a; the second suction port 121 is located near the second end 1b, so that the inlet end 2112 of the second valve 21b can be directed toward the second end 1b.

[0057] In the above design, on the one hand, the positions of the first valve 21a and the second valve 21b are reasonably arranged and meet the requirements of gravity-type check valves; on the other hand, this design allows the outlet ends 2111 of the first valve 21a and the second valve 21b to be closer to the drain outlet 13, which can effectively shorten the connection path between the first valve 21a and the second valve 21b and the drain outlet 13, thereby improving the rationality of the drain channel structure and helping to reduce the design difficulty of the drain channel.

[0058] In some embodiments, please refer to Figure 4 and Figure 10 In the extending direction of the base 1, the first valve 21a and the second valve 21b can be symmetrically arranged on opposite sides of the drain port 13.

[0059] The symmetrical arrangement of the first valve 21a and the second valve 21b includes both directional symmetry and functional symmetry. "Directional symmetry" can be understood as the inlet ends 2112 and outlet ends 2111 of the first valve 21a and the second valve 21b being mirror images of each other. "Functional symmetry" can be understood as the response logic of the first valve 21a and the second valve 21b being mirror images. For example, when the cleaning unit 100 is used vertically and moves horizontally on the working surface, the valve in the lower drain channel can be opened under gravity, and the valve in the upper drain channel can be closed under gravity. The spatial symmetry of the two valves is used to achieve functional symmetry. This functional symmetry is also used to ensure that only one side of the drain channel remains open in special circumstances, where the valve core 212 moves within the valve body 211 due to gravity. It should be noted that the positions of the first valve 21a and the second valve 21b in space can be symmetrical or asymmetrical with respect to the center lines of the first suction port 111 and the second suction port 121.

[0060] In some embodiments, please refer to Figure 7 and Figure 8 A stop structure 213 is provided between the outlet end 2111 and the inlet end 2112 of the valve body 211, and the valve core 212 is movably disposed in the moving channel 214 between the outlet end 2111 and the stop structure 213 of the valve body 211.

[0061] The stop structure 213 is used to restrict the movement of the valve core 212 and prevent the valve core 212 from moving to the inlet end 2112 of the valve body 211. Specifically, the valve body 211 has a valve core cavity and an outlet end 2111 and an inlet end 2112 communicating with the valve core cavity. The stop structure 213 is located in the valve core cavity and can be located close to the inlet end 2112. When the valve core 212 moves in the valve core cavity, the valve core 212 can abut against the stop structure 213. At this time, the outlet end 2111 and the inlet end 2112 of the valve body 211 are in a communicating state, and fluid can pass through the valve core 212. Alternatively, the valve core 212 can also abut against the outlet end 2111. At this time, the contact surface between the valve core 212 and the valve body 211 is a sealing surface, and the outlet end 2111 and the inlet end 2112 of the valve body 211 are in a cut-off state, and fluid cannot pass through the valve body 211.

[0062] In the above embodiments, the stop structure 213 can abut against the valve core 212 to prevent the valve core 212 from directly abutting against the inlet end 2112 and blocking the valve body 211. The moving channel 214 can limit the moving trajectory of the valve core 212, reducing the risk of valve core 212 deviating and causing sealing failure. Thus, the above design effectively improves the reliability of the valve.

[0063] In some embodiments, please refer toFigure 8 and Figure 9 The inner wall of the moving channel 214 is provided with at least one connecting groove 215, which connects the inlet end 2112 and the outlet end 2111 of the valve body 211.

[0064] The connecting groove 215 can be a groove provided on the inner wall of the valve body 211; there can be one, two or more connecting grooves 215. As an example, the valve body 211 can be cylindrical, and the inner wall of the valve body 211 is provided with four connecting grooves 215 extending along the axial direction of the valve body 211. The four connecting grooves 215 are also distributed at intervals along the circumference of the valve body 211.

[0065] In the above design, by providing a connecting groove 215 on the inner wall of the moving channel 214, it is possible to prevent the valve core 212 from completely blocking the valve body 211 when it moves in the moving channel 214 or when it abuts against the stop structure 213, thus ensuring that the valve can be used normally.

[0066] In some embodiments, please refer to Figure 8 and Figure 9 The stop structure 213 is provided with a through hole 2131, and the outline dimension of the through hole 2131 is smaller than the outer outline dimension of the valve core 212.

[0067] As an example, the valve core 212 can be spherical, and the stop structure 213 includes a stop ring. The center of the stop ring is provided with a circular through hole 2131. The diameter of the through hole 2131 is smaller than the diameter of the valve core 212. The through hole 2131 can limit the valve core 212.

[0068] In the above design, the valve core 212 is held in place by the through hole 2131, which can prevent the valve core 212 from shaking when it is against the stop structure 213, thus further improving the reliability of the valve.

[0069] Understandably, in some other embodiments, please refer to Figure 11 and Figure 12 The stop structure 213 can also be multiple protrusions provided on the inner wall of the valve body 211, and the multiple protrusions can jointly abut against the valve core 212.

[0070] In some embodiments, please refer to Figure 10 The gravity-type check valve is positioned parallel to the extension direction of base 1; please refer to... Figure 4 In the direction perpendicular to the extension direction of base 1 (e.g.) Figure 4 (In the direction shown in Y), the distance between the outlet end 2111 of the valve body 211 and the cleaning component 3 is greater than the distance between the inlet end 2112 of the valve body 211 and the cleaning component 3.

[0071] When the cleaning unit 100 provided in the above embodiment is used on a horizontal surface, in the vertical direction, the height of the outlet end 2111 of the valve body 211 is higher than the height of the inlet end 2112. In this way, the valve core 212 can move to the stop structure 213 under the action of gravity, so that the valve can be kept in the open state and the sewage discharge channel can be used normally.

[0072] Understandably, in some other embodiments, the first valve 21a and the second valve 21b may also be solenoid valves, which switch between opening and closing based on a control signal. For example, an attitude sensor (not shown) is provided on the cleaning unit 100. The attitude sensor is used to detect the attitude of the cleaning unit 100, including the relative height of the first end 1a and the second end 1b. A controller (not shown) is also provided on the cleaning device 1000. The controller can communicate with the attitude sensor and the first valve 21a and the second valve 21b, and control the opening and closing of the first valve 21a and the second valve 21b according to the data from the attitude sensor.

[0073] In some embodiments, refer to Figure 4 The first sewage discharge channel 11 and the second sewage discharge channel 12 include a sewage pipe 14.

[0074] Specifically, the sewage pipe 14 of the first sewage channel 11 is connected between the first sewage suction port 111 and the sewage discharge port 13, and the sewage pipe 14 of the second sewage channel 12 is connected between the second sewage suction port 121 and the sewage discharge port 13.
