Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a wastewater tank, cleaning equipment, and cleaning system for a cleaning device. Background Technology

[0002] Cleaning equipment is a device capable of automatically cleaning surfaces and is widely used in people's daily lives and work. For example, cleaning equipment can include floor scrubbers. When cleaning equipment cleans a surface, the suction device sucks up the dirt and temporarily stores it in a wastewater tank, thus achieving the automatic cleaning function.

[0003] To meet the cleaning needs of low-ceilinged spaces, cleaning equipment typically operates in a horizontal position. When used in this horizontal position, the tank lid module usually has a surge protection function to suppress surges caused by sloshing of liquid in the tank and prevent dirt from entering the suction device through the suction port. However, when installing the lid module onto the tank, users need to confirm the corresponding installation position of the lid module and the tank body to avoid the surge suppression function of the lid module failing due to incorrect installation. This not only causes assembly inconvenience but also may leave the suction device at risk of water ingress in the event of misinstallation.

[0004] Therefore, simplifying the assembly process of the cover and avoiding surge suppression failure due to incorrect installation direction has become a technical problem to be solved. Utility Model Content

[0005] This application provides a wastewater tank, cleaning equipment, and cleaning system for a cleaning device, which simplifies the assembly process of the tank cover and avoids surge suppression failure caused by incorrect installation direction.

[0006] In a first aspect, embodiments of this application provide a wastewater tank for a cleaning device, comprising:

[0007] The box has a sewage inlet pipe and a first side wall in the circumferential direction;

[0008] The lid module has a suction port; the lid module is located on the top of the box and is assembled with the box to form a sludge storage chamber; the suction port is connected to the sludge storage chamber and is used to extract the gas in the sludge storage chamber to create a negative pressure environment in the sludge storage chamber.

[0009] The stopper is rotatably mounted on the cover module. The stopper is used to prevent some of the dirt in the sludge storage chamber from moving toward the suction port. The stopper has a clearance notch, which is used to allow the sludge inlet pipe to pass during the assembly of the cover module and the box body. The clearance notch rotates with the stopper.

[0010] The sewage inlet pipe has a guide surface. During the assembly of the cover module into the box body, the guide surface guides the blocking component to rotate to one side of the first side wall, so that the clearance notch rotates to the assembly position that matches the sewage inlet pipe.

[0011] The wastewater tank of the cleaning equipment provided in this application embodiment is equipped with a stopper. In the lying-flat state, the first side wall is adjacent to the surface to be cleaned. When the wastewater tank is applied to the cleaning equipment and the cleaning equipment is moved back and forth by the user in the lying-flat position, the dirt in the wastewater tank may move under the action of inertia and cause a surge, so as to drive the stopper to rotate relative to the tank cover module. In order to block some of the dirt from moving toward the side of the suction port by the stopper, while suppressing the surge, the dirt can also be blocked in the dirt storage chamber, so as to reduce the risk of dirt entering the suction device through the suction port, thereby reducing the risk of liquid damage to the suction device.

[0012] Furthermore, the abutment is provided with a clearance notch. When assembling the cover module and the box body, the clearance notch can avoid the sewage inlet pipe, so as to avoid interference between the sewage inlet pipe and the abutment, thereby avoiding structural damage caused by hard contact between the abutment and the sewage inlet pipe.

[0013] During the assembly of the cover module into the housing, the guide surface of the sewage inlet pipe allows the blocking component to rotate towards the first side wall if the user's installation direction is correct. This allows the clearance notch to rotate to the assembly position that mates with the sewage inlet pipe, providing intuitive installation feedback to the user. The user can clearly perceive that the cover module is smoothly installed under the guidance of the guide surface without the need for additional force or repeated adjustments. This simplifies the assembly process of the cover module and the housing, avoids damage to components due to improper operation, and improves the user experience.

[0014] Meanwhile, if the user's installation orientation is incorrect, the inlet pipe will interfere with the blocking component, creating significant assembly resistance. This resistance will be immediately fed back to the user through tactile feedback, making the user clearly aware that there is an abnormality in the current operation. This interference feedback forms a "mistake prevention" mechanism, prompting the user to stop the current operation and adjust the installation orientation, thus avoiding damage to components or structural deformation that may result from forced assembly.

[0015] Therefore, by setting guide surfaces on the sewage pipe, users can clearly perceive whether the current assembly direction is correct when assembling the cover module and the tank body. This not only protects the integrity of the sewage tank structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the cover module and the tank body.

[0016] In some embodiments, during the assembly of the cover module into the box body, and when the abutment is not in contact with the guide surface, the abutment is in a free-falling state relative to the cover; the guide surface is the end face of the sewage inlet pipe at the top, and during the assembly of the cover module into the box body, the guide surface of the abutment contacts the abutment first.

[0017] With this design, when the user assembles the cover module into the housing in the correct orientation, the guide surface at the top of the sewage inlet pipe will first contact the stop component in its downward position. As the guide surface contacts the clearance notch, it guides the clearance notch to rotate, thus successfully completing the assembly.

[0018] When the user assembles the tank cover module in the wrong direction, the guide surface and the stop part cannot make effective contact and guidance, resulting in direct interference and obvious assembly resistance. This provides the user with timely tactile feedback, allowing the user to clearly perceive the current installation direction error and adjust the direction in time. This improves the accuracy of sewage tank assembly, avoids the failure of surge suppression function due to incorrect installation direction, and reduces the risk of damage to the suction device.

[0019] In some embodiments, the guide surface is a first inclined surface of the top wall of the inlet pipe on the side adjacent to the first side wall;

[0020] During the assembly of the cover module into the box body, the first inclined surface is configured to contact the stop component before other structures of the sewage inlet pipe and to provide rotational force to the stop component. This rotational force can be decomposed into a lateral rotational component, so that the stop component rotates toward one side of the cover under the action of the rotational force.

[0021] With this design, when the user applies assembly force to the tank cover module, the first inclined surface provides rotational force to the abutment, driving it to rotate towards the tank cover module. This allows the user to perceive that the current installation orientation is correct. Conversely, if the installation orientation is incorrect, the abutment will interfere with the first inclined surface, providing the user with noticeable resistance. This prompts the user to adjust the assembly orientation promptly, preventing damage to components due to incorrect installation and ensuring the abutment ultimately reaches the correct working position, thus guaranteeing the proper functioning of the sewage tank's surge suppression function.

[0022] In some embodiments, the abutment is an arc-shaped plate that can surround the circumference of the inlet pipe portion, and the first inclined surface is an arc-shaped surface extending circumferentially along the inlet pipe. Thus, when the first inclined surface contacts the arc-shaped plate-like abutment, the arc-shaped surface structure and the contour of the arc-shaped inner wall of the abutment can match each other, thereby increasing the contact area between the first inclined surface and the abutment, making the distribution of guiding force more uniform, and improving the magnitude and stability of the lateral component force acting on the abutment. It should be noted that the arc-shaped surface is hollow, with an elliptical-like contour, which can be obtained by creating an elliptical contour through an inclined section on the inlet pipe.

[0023] In some embodiments, the tank cover module further includes a water-blocking component, which includes a first water-blocking element disposed at the bottom of the tank cover. The first water-blocking element is disposed at the top of the sewage inlet pipe and surrounds the side of the sewage inlet pipe adjacent to the first sidewall in the circumferential direction, so as to prevent the dirt output from the sewage inlet pipe from moving toward the suction port. When the sewage inlet pipe sucks the dirt from the cleaning process of the cleaning equipment into the sewage tank through the sewage inlet pipe under the action of pressure difference, the dirt can directly enter the sewage storage chamber under the obstruction and guidance of the first water-blocking element, so as not to enter the suction device through the suction port, thus avoiding liquid damage to the suction device.

[0024] The bottom end of the abutment is rotatably connected to the first water-blocking component, so that the abutment is rotatably connected to the box cover module through the first water-blocking component, so that the abutment is rotatably set on the box cover module while the abutment is set on the side close to the first side wall.

[0025] In some embodiments, the first water-blocking component is provided with a rotation limiting structure. The rotation limiting structure is used to limit the rotation range of the blocking component so as to limit the rotation angle of the blocking component within a preset range. In this way, when the blocking component rotates towards the box cover module, it can be limited by the rotation limiting structure so that the blocking component is relatively fixed to the box cover module, blocking dirt and suppressing the surge of dirt, preventing dirt from entering the suction device through the suction port, and reducing the risk of liquid damage to the suction device.

[0026] In some embodiments, when the abutment is assembled in the housing, the abutment has a blocking position and an open position when rotating relative to the inlet pipe; during the process of the abutment rotating from the open position to the blocking position, the gap between the abutment and the first side wall gradually decreases, and the distance between the free end of the abutment and the inner bottom wall of the sludge storage cavity gradually increases. This allows the abutment to be closer to the first side wall in the sludge storage cavity and to rotate toward the side closer to the housing cover module. Thus, when the abutment is in the blocking position, it can better prevent some of the dirt in the sludge storage cavity from moving toward the suction port.

[0027] In some embodiments, when the stopper is assembled into the housing, the stopper abuts against a portion of the circumferential outer wall of the inlet pipe on the side adjacent to the inlet pipe, so that the stopper is in the open position.

[0028] This configuration limits the rotation angle of the blocking component through the inlet pipe, thus restricting the blocking component to the open position. This prevents the blocking component from rotating excessively under the influence of dirt, which would prevent it from switching to the open position under the drive of dirt, and ensures the stability of the blocking component's position switching under different working conditions.

[0029] In some embodiments, when the abutment is assembled into the housing, the abutment is configured to also be able to rotate toward one side of the first sidewall under the drive of dirt in the dirt storage chamber, so that the abutment is in the abutment position;

[0030] The stop is configured to prevent some of the dirt in the storage chamber from moving toward the suction port when it is in the stop position. In order to prevent some of the dirt from moving toward the suction port, the stop can suppress the surge and also block the dirt on the side of the stop facing the bottom wall of the storage chamber, thereby reducing the risk of dirt entering the suction device through the suction port and thus reducing the risk of liquid damage to the suction device.

[0031] In some embodiments, the sewage tank has a horizontal position. When the sewage tank is in the horizontal position:

[0032] The tank body and lid module are arranged sequentially along a direction parallel to the surface to be cleaned, with the first sidewall adjacent to the surface to be cleaned. The stop member is configured to rotate under the drive of dirt in the dirt storage chamber. By cyclically switching between the open and stopped positions, the stop member can block the dirt, suppressing the surge of dirt and preventing it from entering the inner bottom wall of the dirt storage chamber. This reduces the risk of dirt entering the suction port, thus reducing the risk of dirt entering the suction device through the suction port when the wastewater tank is used in cleaning equipment, and consequently reducing the risk of liquid damage to the suction device.

[0033] Meanwhile, by cyclically switching between the open and closed positions of the blocking component, dirt can be collected in the dirt storage chamber on the side away from the cover module, so that users can easily empty the dirt together when cleaning the wastewater tank, reducing the time users spend cleaning the wastewater tank and improving cleaning efficiency and user experience.

[0034] Secondly, embodiments of this application provide a cleaning device, comprising:

[0035] Floor brush assembly, used to clean the surface to be cleaned;

[0036] The body assembly has one end rotatably connected to the floor brush assembly, and the other end of the body assembly is equipped with a handle.

[0037] As in any of the preceding embodiments, the wastewater tank is mounted on the body assembly and rotates with the body assembly.

[0038] The cleaning equipment provided in this application embodiment has the aforementioned sewage tank, and therefore has the beneficial effects of the aforementioned sewage tank. During the assembly of the tank cover module into the tank body, the guide surface can guide the blocking component to rotate to one side of the first side wall, so that the clearance notch rotates to the assembly position that matches the sewage inlet pipe, thereby providing users with intuitive installation feedback, allowing users to clearly perceive whether the current assembly direction is correct. This not only protects the integrity of the sewage tank structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the tank cover module and the tank body.

[0039] Thirdly, embodiments of this application provide a cleaning system, including:

[0040] Base station, which has storage space inside;

[0041] As in any of the preceding embodiments of the cleaning apparatus, the cleaning module in the cleaning apparatus may be disposed within the accommodating space.

[0042] The cleaning system provided in this application embodiment has the aforementioned cleaning equipment, and therefore has the beneficial effects of the aforementioned cleaning equipment. During the assembly of the tank cover module into the tank body, the guide surface can guide the blocking component to rotate to one side of the first side wall, so that the clearance notch rotates to the assembly position that matches the sewage inlet pipe, thereby providing users with intuitive installation feedback, allowing users to clearly perceive whether the current assembly direction is correct. This not only protects the integrity of the sewage tank structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the tank cover module and the tank body.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0065] This application provides a cleaning device. The cleaning device may include a robotic vacuum cleaner, a floor scrubber, or other equipment capable of cleaning surfaces. For example, the surface to be cleaned may be a floor. The following description primarily uses the scenario of the cleaning device cleaning a floor as an example to illustrate the structure of the cleaning device.

[0066] Figure 1 This is a schematic diagram of the structure of a cleaning device 100 provided in an embodiment of this application.

[0067] Please refer to Figure 1 Specifically, the cleaning device 100 includes a body assembly 3 and a floor brush assembly 2. The floor brush assembly 2 is located at the bottom of the body assembly 3 to clean the surface to be cleaned. A handle 4 is provided at the end of the body assembly 3 away from the surface to be cleaned so that the user can hold it and push the cleaning device 100 to clean the surface.

[0068] The floor brush assembly 2 includes a mounting base and a roller brush. The mounting base is rotatably mounted on the bottom of the body assembly 3, and the roller brush is located on the side of the mounting base facing the surface to be cleaned. When the roller brush rotates relative to the mounting base, the roller can contact the surface to be cleaned, thereby cleaning the surface.

[0069] The cleaning device 100 also includes a clean water tank, which is mounted on the body assembly 3 and positioned away from the floor brush assembly 2. The clean water tank supplies clean water to the floor brush assembly 2 or the surface to be cleaned, allowing the floor brush assembly 2 to better clean the surface. This process also generates wastewater. The floor brush assembly 2 also absorbs impurities from the surface during cleaning. These impurities may include paper scraps, food crumbs, hair, etc.

[0070] The cleaning equipment 100 also includes a water pump that can pump clean water from the clean water tank to the floor brush assembly 2. The installation position of the water pump in the cleaning equipment 100 can be determined according to the existing structure of the cleaning equipment 100, and will not be described in detail here.

[0071] The cleaning device 100 may include a walking mechanism. The floor brush assembly 2 is mounted on the walking mechanism. When the cleaning device 100 is in operation, the user can push the handle 4 of the cleaning device 100, which, driven by the walking mechanism, causes the cleaning device 100 to move in different directions, thereby cleaning the surface to be cleaned by the floor brush assembly 2.

[0072] Please refer to Figure 1 The cleaning device 100 may include a wastewater tank 1. The wastewater tank 1 is also installed on the side of the floor brush assembly 2 away from the surface to be cleaned. The wastewater tank 1 has a suction port and a wastewater storage chamber. The suction port is located at the top of the wastewater tank 1 and communicates with the wastewater storage chamber. The suction port is used to extract gas from the wastewater storage chamber to create a negative pressure environment in the wastewater storage chamber, so that dirt generated during the cleaning process by the cleaning device 100 can be sucked into the wastewater storage chamber for centralized storage under the pressure difference. This allows the user to centrally empty the dirt in the wastewater tank 1 after the cleaning device 100 has completed its cleaning operation. The top of the wastewater tank 1 refers to the end of the wastewater tank 1 away from the floor brush assembly 2. Correspondingly, the bottom of the wastewater tank 1 refers to the end of the wastewater tank 1 closest to the floor brush assembly 2.

[0073] It should be noted that the dirt in the cleaning process can include the wastewater, impurities, and mixtures of dirt generated during the cleaning process mentioned above.

[0074] The cleaning equipment 100 may include a suction device. For example, the suction device may be a suction pump. The suction device is located on the side of the wastewater tank 1 where the suction port is provided, and is fixed relative to the wastewater tank 1. That is, the positions of the suction device and the wastewater tank 1 do not change relative to each other on the cleaning equipment 100. The suction device is configured to suction from the suction port, removing gas from the wastewater storage chamber to create a negative pressure environment in the wastewater storage chamber, so that dirt generated during the cleaning process of the cleaning equipment 100 can be sucked into the wastewater storage chamber for centralized storage under the action of pressure difference.

[0075] To meet the cleaning needs of low-ceilinged spaces (such as under beds and sofas), the cleaning device 100 is equipped with a lying-flat function. For example, when the cleaning device 100 is used lying flat, its body component 3 can be used in a nearly parallel position to the surface to be cleaned, allowing for scenarios where the cleaning device 100 can be pushed and pulled back and forth on the surface to be cleaned. It should be noted that the scenarios where the cleaning device 100 can be pushed and pulled back and forth on the surface to be cleaned can include scenarios where the user pushes the cleaning device 100 forward and scenarios where the user pushes the cleaning device 100 backward.

[0076] To meet the needs of the cleaning equipment 100 when it is used in a flat position, the wastewater tank, clean water tank, suction device, etc. of the cleaning equipment can rotate relative to the floor brush assembly 2, so that the cleaning equipment 100 can switch between a flat position and an upright position.

[0077] Please refer to Figure 1When the cleaning equipment 100 is in an upright position, the part of the cleaning equipment 100 excluding the walking mechanism and the cleaning module (such as the sewage tank 1) stands on the surface to be cleaned. At this time, the sewage tank 1 is also in an upright position, with the suction port of the sewage tank 1 away from the surface to be cleaned, and the suction device located above the suction port.

[0078] The wastewater tank 1 can rotate relative to the brush assembly 2 so that when the cleaning equipment 100 switches between a lying position and an upright position, the wastewater tank 1 can also switch between a lying position and an upright position simultaneously.

[0079] In related technologies, because the cleaning equipment, excluding the walking mechanism and floor brush components (such as the wastewater tank), can be used in a nearly parallel, horizontal position to the surface to be cleaned, both the wastewater tank and the suction device are mounted on the main body, placing them close to the surface. When the cleaning equipment is used in this horizontal position and is pushed back and forth on the surface, the dirt in the wastewater tank contains a large amount of wastewater, causing it to shake violently and create a "surge." This surge causes significant fluctuations in the wastewater tank's surface level and even splashes. Since the wastewater tank's suction port is connected to the suction device, the splashed droplets are more likely to flow through the suction port to the suction device, significantly increasing the risk of damage to the suction device due to liquid ingress.

[0080] To suppress the surge of dirt, the cover modules in related technologies typically have surge protection functions to block the sloshing dirt. However, when installing the cover module onto the tank, users need to confirm the corresponding installation position of the cover module and the tank to avoid the surge suppression function of the cover module failing due to incorrect installation. This not only causes assembly inconvenience but may also leave the suction device at risk of water ingress in the event of misinstallation.

[0081] Therefore, simplifying the assembly process of the box cover and avoiding functional failure due to incorrect installation direction has become a technical problem to be solved.

[0082] In view of this, this application embodiment also provides a sewage tank for cleaning equipment. Through the guide surface on the sewage pipe, if the user's installation direction is correct, the guide surface can guide the abutment to rotate towards one side of the first sidewall, causing the clearance notch to rotate to the assembly position that mates with the sewage inlet pipe. This provides the user with intuitive installation feedback, allowing the user to clearly perceive that the tank cover module is smoothly installed under the guidance of the guide surface, without the need for additional force or repeated adjustments. If the user's installation direction is incorrect, the sewage inlet pipe will interfere with the abutment, generating significant assembly resistance. This resistance will immediately be fed back to the user through tactile feedback, allowing the user to clearly perceive an abnormality in the current operation. This interference feedback forms a "mistake prevention" mechanism, prompting the user to stop the current operation and adjust the installation direction, avoiding component damage or structural deformation that may result from forced assembly. This protects the integrity of the sewage tank structure, reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the tank cover module and the tank body.

[0083] The wastewater tank of the cleaning equipment provided in the embodiments of this application will be further described below with reference to the accompanying drawings.

[0084] Figure 2 This is a schematic diagram of the sewage tank 1 provided in the embodiments of this application in an upright state. Figure 3 for Figure 2 A schematic diagram of the structure of the wastewater tank 1 in its lying-flat state. Figure 4 for Figure 3 A schematic diagram of the cross-section of the wastewater tank 1 along the AA direction.

[0085] Please refer to Figure 2 , Figure 2 and Figure 4 The wastewater tank 1 includes a cover module 20 and a tank body 10. The cover module 20 is installed on the top of the tank body 10 and is assembled with the tank body 10 to form a wastewater storage chamber 30. The cover module 20 has a suction port 22, and the wastewater storage chamber 30 is connected to the suction port 22. The suction port 22 is used to extract gas from the wastewater storage chamber 30 to create a negative pressure environment in the wastewater storage chamber 30.

[0086] Please refer to Figure 1 and Figure 4 The housing 10 has a dirt inlet pipe 11, which can suck the dirt collected and generated by the cleaning equipment 100 during the cleaning process into the dirt storage chamber 30 under the action of pressure difference, so that the dirt generated by the cleaning equipment 100 during the cleaning process can be stored in the dirt storage chamber 30 for the user to perform unified cleaning later.

[0087] Please refer to Figure 1 , Figure 2 and Figure 4Specifically, the cleaning equipment 100 has a suction device that can suction through the suction port 22, thereby drawing the gas in the sewage storage chamber 30 out of the sewage tank 1 through the suction port 22 and into the suction device, so that a pressure difference is formed inside and outside the sewage tank 1 in the sewage storage chamber 30, and a negative pressure environment is formed inside the sewage storage chamber 30. In this way, under the action of the pressure difference, the sewage inlet pipe 11 can suck the dirt generated during the cleaning process of the cleaning equipment 100 into the sewage storage chamber 30 through the outlet end of the sewage inlet pipe 11.

[0088] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the tank body 10 has a first side wall 12 in the circumferential direction. When the sewage tank 1 is in an upright state, the tank body 10 and the cover module 20 of the sewage tank 1 are arranged in sequence along the direction perpendicular to the surface to be cleaned 200. At this time, the first side wall 12 is perpendicular to the surface to be cleaned 200. The dirt generated by the cleaning device 100 during the cleaning process enters the sewage inlet pipe 11 under the action of pressure difference and then enters the sewage storage chamber 30 for storage.

[0089] When the cleaning device 100 is used in a horizontal position, the wastewater tank 1 is also in a horizontal position. At this time, the first side wall 12 is close to the surface to be cleaned 200, and the dirt in the wastewater tank 1 will accumulate at the first side wall 12 under the action of gravity. If the user repeatedly pushes the cleaning device 100 to clean the surface to be cleaned 200 at this time, the dirt in the wastewater tank 1 will move back and forth towards or away from the tank cover module 20 under the action of inertia, causing a surge. When the surge height is high, some dirt may surge towards the gap between the wastewater inlet pipe 11 and the tank cover module 20 in the direction away from the surface to be cleaned 200, and move towards one side of the suction port 22, resulting in a greater risk of liquid inlet damage to the suction device.

[0090] Therefore, the wastewater tank 1 provided in this embodiment includes a stop member 40, which is rotatably mounted on the tank cover module 20. When the dirt in the wastewater tank 1 surges and moves toward the side close to the tank cover module 20, the dirt can drive the stop member 40 to rotate, so that the stop member 40 blocks the dirt and suppresses the surge of dirt, blocking the dirt on the side of the stop member 40 toward the inner bottom wall of the dirt storage chamber 30, thereby reducing the risk of dirt entering the suction port 22. When the wastewater tank 1 is applied to the cleaning equipment 100, the risk of dirt entering the suction device through the suction port 22 is reduced, thereby reducing the risk of liquid damage to the suction device.

[0091] The inner bottom wall of the sludge storage chamber 30 mentioned above is the side of the sludge storage chamber 30 that is close to the surface 200 to be cleaned when the cleaning equipment 100 is in normal use.

[0092] Please refer to Figure 1It should be noted that the normal use of the cleaning equipment 100 mentioned above refers to the non-lying-flat usage state of the cleaning equipment 100. For example, during normal use, the cleaning equipment 100 can be used upright or tilted (a usage state between upright and lying flat). Correspondingly, the wastewater tank 1 can be in an upright state, or the wastewater tank 1 can be in a tilted state between an upright state and a lying flat state.

[0093] Please refer to Figure 1 and Figure 4 However, if the circumferential installation orientation of the cover 21 is incorrect when the user installs it, the stop 40 will be in the wrong position. In this state, when the cleaning device 100 is in a flat working posture, the dirt in the dirt storage chamber 30 will accumulate at the first side wall 12 under the action of gravity, and the stop 40, due to its incorrect installation position, will not be able to effectively block the dirt accumulated at the first side wall 12. When the user moves the cleaning device 100 back and forth, the dirt will rush directly towards the suction port 22 under the action of inertia, causing the surge suppression function of the stop 40 to fail, increasing the risk that dirt will enter the suction device through the suction port 22.

[0094] It should be noted that an incorrect position refers to the state in which the abutment 40 is not located at the first side wall 12. For example, the abutment 40 may be located at the side wall opposite to the first side wall 12, or at other unexpected positions in the sludge storage chamber 30.

[0095] Please refer to Figure 4 In this embodiment, the sewage inlet pipe 11 has a guide surface, and the abutment 40 is provided with an avoidance notch 41 to avoid the sewage inlet pipe 11 during the assembly of the box cover module 20 and the box body 10, and the avoidance notch 41 can rotate with the abutment 40.

[0096] Please refer to Figure 2 and Figure 4 During the assembly of the cover module 20 into the box body 10, since the sewage inlet pipe 11 has a guide surface, if the user's installation direction is correct, the guide surface can guide the stop part 40 to rotate to one side of the first side wall 12, so that the clearance notch 41 rotates to the assembly position that matches the sewage inlet pipe 11. This provides the user with intuitive installation feedback, allowing the user to clearly perceive that the cover module 20 is smoothly installed under the guidance of the guide surface without the need to apply additional force or make repeated adjustments. This simplifies the assembly process of the cover module 20 and the box body 10, avoids damage to components due to improper operation, and improves the user experience.

[0097] Meanwhile, if the user's installation orientation is incorrect, the inlet pipe 11 will interfere with the blocking component 40, generating significant assembly resistance. This resistance will be immediately fed back to the user through tactile feedback, making the user clearly aware that there is an abnormality in the current operation. This interference feedback forms a "mistake prevention" mechanism, prompting the user to stop the current operation and adjust the installation orientation, thus avoiding component damage or structural deformation that may result from forced assembly.

[0098] Therefore, by setting the guide surface on the sewage pipe, the user can clearly perceive whether the current assembly direction is correct when assembling the cover module 20 and the tank body 10. This not only protects the integrity of the sewage tank 1 structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the cover module 20 and the tank body 10.

[0099] Figure 8 for Figure 2 An explosion diagram of wastewater tank 1. Figure 9 for Figure 8 A schematic diagram of the cross-section of the wastewater tank 1 along the CC direction.

[0100] Please refer to Figure 2 , Figure 4 , Figure 8 and Figure 9 In some embodiments, during the assembly of the cover module 20 into the box body 10, and before the abutment 40 contacts the guide surface, the abutment 40 is in a free-falling state relative to the cover 21. The guide surface is the end face of the sewage inlet pipe 11 at the top. During the assembly of the cover module 20 into the box body 10, the guide surface of the abutment 40 contacts the abutment 40 first.

[0101] in, Figure 8 and Figure 9 All the blocking parts 40 are in a free-falling state.

[0102] Specifically, in the initial stage of assembly of the lid module 20 and the box body 10, since the stop 40 is rotatably mounted on the lid module 20, the stop 40 can be in a free-falling state under the action of gravity.

[0103] When the user assembles the cover module 20 into the box body 10 in the correct direction, the guide surface at the top of the sewage pipe 11 will first contact the stop 40 in the hanging state. As the guide surface contacts the clearance notch 41, the guide surface can guide the clearance notch 41 to rotate, thus completing the assembly smoothly.

[0104] Please refer to Figure 8 and Figure 9When the user assembles the tank cover module 20 in the wrong direction, the guide surface and the stop part 40 cannot make effective contact and guide, and direct interference will occur, resulting in obvious assembly resistance. This provides the user with timely tactile feedback, allowing the user to clearly perceive the current installation direction error and adjust the direction in time, thereby improving the accuracy of the sewage tank 1 assembly, avoiding the failure of the surge suppression function due to incorrect installation direction, and reducing the risk of damage to the suction device.

[0105] Please refer to Figure 2 and Figure 4 In some embodiments, the guide surface is a first inclined surface 111 provided on the top wall of the sewage inlet pipe 11 on the side adjacent to the first side wall 12. During the assembly of the cover module 20 into the box body 10, the first inclined surface 111 is configured to contact the stop member 40 in priority over other structures of the sewage inlet pipe 11 and provide a rotational force to the stop member 40. This rotational force can be decomposed into a lateral rotational component, so that the stop member 40 rotates toward one side of the cover 21 under the action of the rotational force.

[0106] Please refer to Figure 2 and Figure 4 Specifically, during the assembly of the lid module 20 and the box body 10, the lid module 20 and the box body 10 move closer to each other, that is, the lid module 20 moves downward relative to the box body 10. When the lid module 20 is assembled downward, the edge of the clearance notch 41 of the abutment 40 will first contact the first inclined surface 111. Since the first inclined surface 111 is an inclined structure, when the user continues to apply a downward assembly force, the first inclined surface 111 can decompose the vertically downward separation into a normal force perpendicular to the first inclined surface 111 and a tangential force (rotational force) parallel to the first inclined surface 111 and pointing towards the first sidewall 12. The rotational force can generate a rotational torque on the abutment 40, driving the abutment 40 to rotate closer to the first sidewall 12. As the assembly process continues, the abutment 40 can slide along the first inclined surface 111 and gradually rotate until it passes the first inclined surface 111 and reaches the preset installation position.

[0107] Conversely, if the tank cover module 20 is installed in the wrong direction, the highest point or adjacent area of ​​the first inclined surface 111 will come into contact with the abutment 40. Due to the incorrect installation direction, the contact position between the abutment 40 and the first inclined surface 111 cannot form a guide slope structure. Therefore, the abutment 40 and the sewage inlet pipe 11 will form rigid interference at this point, generating significant assembly resistance. This rigid interference will immediately transmit feedback signals of incorrect installation to the user through changes in feel, prompting the user to adjust the assembly direction in a timely manner, avoiding damage to components caused by incorrect installation, and ensuring that the abutment 40 can eventually reach the correct working position, thereby ensuring the normal realization of the surge suppression function of the sewage tank 1.

[0108] Please refer to Figure 2and Figure 4 In this embodiment, the first inclined surface 111 slopes from the outer wall of the inlet pipe 11 away from the first side wall 12 to the outer wall close to the first side wall 12, and the highest point of the first inclined surface 111 (the side away from the inner bottom wall of the box 10) is located away from the first side wall 12. When the box cover module 20 is assembled in the correct direction, the abutment 40 slides from the high point (the side away from the first side wall 12) of the first inclined surface 111 to the low point (the side close to the first side wall 12). During this downward sliding process, the normal force generated by the first inclined surface 111 can be decomposed into a torque that causes the abutment 40 to rotate in the direction of the box cover 21, thereby achieving smooth guidance and avoidance.

[0109] It should be noted that this embodiment does not impose any restrictions on the tilt angle of the first tilting surface 111, and can be adapted to meet actual needs.

[0110] Figure 6 for Figure 4 Schematic diagram of the structure of the first water-blocking component 23 and the blocking component 40 Figure 1 .

[0111] Please refer to Figure 4 and Figure 6 In some embodiments, the abutment 40 is an arc-shaped plate that can surround part of the circumference of the sewage inlet pipe 11, and the first inclined surface 111 is an arc-shaped surface that extends along the circumference of the sewage inlet pipe 11.

[0112] Specifically, the shapes of the arc-shaped plate and the arc-shaped surface are matched. When the first inclined surface 111 contacts the arc-shaped plate-shaped stop 40, the arc-shaped surface structure and the contour of the arc-shaped inner wall of the stop 40 can match each other, thereby increasing the contact area between the first inclined surface 111 and the stop 40, making the distribution of guiding force more uniform, and improving the magnitude and stability of the rotational force acting on the stop 40.

[0113] This allows the lateral force generated by the first inclined surface 111 to more reliably drive the stop 40 to rotate, ensuring that the stop 40 moves along the preset trajectory without deviating or getting stuck, improving the smoothness and reliability of the assembly process, and avoiding the problem of the stop 40 and the first inclined surface 111 getting stuck during the assembly process.

[0114] It should be noted that the arc-shaped surface of the first inclined surface 111 is a hollow structure with an elliptical outline, which can be obtained by using an inclined section on the sewage inlet pipe 11.

[0115] Figure 7 for Figure 6 A structural diagram from another perspective.

[0116] Please refer to Figure 4 , Figure 6and Figure 7 In some embodiments, the cover module 20 further includes a water-blocking component, which includes a first water-blocking member 23. The first water-blocking member 23 is disposed at the bottom end of the cover 21, and is positioned at the top of the sewage inlet pipe 11 and surrounds the sewage inlet pipe 11 on the side of the circumferential adjacent to the first sidewall 12.

[0117] Please refer to Figure 1 , Figure 2 and Figure 4 Specifically, the cover module 20 also includes a cover 21, which is installed on the top of the body 10. A sealing structure can be provided between the cover 21 and the inner wall of the body 10 to ensure the sealing of the wastewater tank 1 at the connection between the cover 21 and the body 10. For example, the sealing structure can be a sealing ring. The top of the body 10 can be understood as the side of the wastewater tank 1 away from the surface 200 to be cleaned when the wastewater tank 1 is applied to the cleaning equipment 100 and the cleaning equipment 100 is in an upright state. The bottom of the wastewater tank 1 can be understood as the side of the wastewater tank 1 close to the surface 200 to be cleaned.

[0118] When the cover 21 is placed on the tank body 10, the first water baffle 23 is located inside the tank body 10 and is blocked on the top wall of the sewage inlet pipe 11. When the sewage inlet pipe 11 sucks the dirt from the cleaning process of the cleaning equipment 100 into the sewage tank 1 under the action of pressure difference, the dirt can directly enter the sewage storage chamber 30 under the obstruction and guidance of the first water baffle 23, and will not enter the suction device through the suction port 22, thus avoiding damage to the suction device.

[0119] Please refer to Figure 1 and Figure 4 The first water-blocking component 23 is located at the top of the sewage inlet pipe 11, that is, at the end of the sewage inlet pipe 11 near the tank cover module 20, thereby directly blocking the suction port 22. When the sewage tank 1 is in working condition, the dirt output from the sewage inlet pipe 11 is blocked by the first water-blocking component 23, which can prevent the dirt from splashing upwards to the area near the suction port 22.

[0120] Please refer to Figure 1 and Figure 4 In this embodiment, the first water-blocking member 23 is arranged around the sewage inlet pipe 11 on the side adjacent to the first side wall 12 in the circumferential direction. This forms an isolation structure between the first side wall 12 and the suction port 22. When the cleaning device 100 is used lying flat, the dirt entering the sewage storage chamber 30 can be restricted to the area between the first water-blocking member 23 and the first side wall 12. At this time, even if some dirt crosses the blocking member 40 under strong surge, it will be blocked by the first water-blocking member 23 and cannot enter the space where the suction port 22 is located, further reducing the risk of dirt in the sewage tank 1 entering the suction device.

[0121] Please refer to Figure 1 and Figure 4In this embodiment, the abutment 40 is rotatably connected to the bottom end of the first water-blocking member 23, thereby realizing the rotatable connection between the abutment 40 and the box cover module 20 through the first water-blocking member 23. This allows the abutment 40 to be rotatably set on the box cover module 20 while being positioned close to the side of the first side wall 12.

[0122] Figure 5 for Figure 3 A schematic diagram of the cross-section of the wastewater tank 1 along the BB direction.

[0123] Please refer to Figure 4 and Figure 5 In some embodiments, when the stop member 40 is assembled inside the housing 10, the stop member 40 has a stop position A and an open position B when rotating relative to the sewage inlet pipe 11. During the process of the stop member 40 rotating from the open position B to the stop position A, the gap between the stop member 40 and the first side wall 12 gradually decreases, and the distance between the free end of the stop member 40 and the inner bottom wall of the sewage storage cavity 30 gradually increases, so that the stop member 40 can be closer to the first side wall 12 in the sewage storage cavity 30 and rotate toward the side closer to the lid module 20. In this way, when the stop member 40 is in the stop position A, it can better prevent some of the dirt in the sewage storage cavity 30 from moving toward the suction port 22.

[0124] It should be noted that, Figure 4 The position of the middle blocking component 40 is the blocking position A. Figure 4 The position indicated by the dashed line is open position B. Figure 5 The position of the middle blocking component 40 is the blocking position A. Figure 5 The position indicated by the dashed line is open position B.

[0125] Please refer to Figure 1 , Figure 4 and Figure 5 Meanwhile, since there is a certain gap between the abutment 40 and the first side wall 12, some dirt will surge into the area between the abutment 40 and the lid module 20 when a surge occurs. As the cleaning device 100 is moved back and forth by the user in a lying position, this dirt may also move towards the inner bottom wall of the dirt storage chamber 30 under the action of inertia and cause a surge, driving the abutment 40 to switch from the abutment position A to the open position B. At this time, since the gap between the abutment 40 and the first side wall 12 gradually increases, this dirt can also be gathered again on the inner bottom wall of the abutment 40 towards the dirt storage chamber 30 through the gap between the abutment 40 and the first side wall 12, thus concentrating the dirt on the inner bottom wall of the dirt storage chamber 30.

[0126] Please refer to Figure 1 , Figure 4 and Figure 5Furthermore, when the user repeatedly moves the cleaning device 100, the dirt can move back and forth within the dirt storage chamber 30, causing the stop member 40 to cycle between the open position B and the stop position A. At this time, the dirt can repeatedly flush the inner wall of the dirt storage chamber 30, thereby collecting the dirt attached to the inner wall of the dirt storage chamber 30 together on the side of the stop member 40 facing the bottom wall of the dirt storage chamber 30. In this way, when the user cleans the wastewater tank 1, the dirt can be emptied together, reducing the time the user spends cleaning the wastewater tank 1 and improving cleaning efficiency and user experience.

[0127] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, when the stop member 40 is assembled inside the housing 10, the stop member 40 is configured to also be able to rotate toward the first sidewall 12 driven by the dirt in the dirt storage chamber 30, so that the stop member 40 is in the stop position A. The stop member 40 is configured to prevent some dirt in the dirt storage chamber 30 from moving toward the suction port 22 when in the stop position A. In order to prevent some dirt from moving toward the suction port 22, the stop member 40 can suppress surges and also block dirt on the side of the stop member 40 toward the inner bottom wall of the dirt storage chamber 30, thereby reducing the risk of dirt entering the suction device through the suction port 22, and thus reducing the risk of liquid damage to the suction device.

[0128] Please refer to Figure 6 and Figure 7 In some embodiments, the first water-blocking member 23 is provided with a rotation limiting structure 231, which is used to limit the rotation range of the blocking member 40.

[0129] Please refer to Figure 4 , Figure 6 and Figure 7 Specifically, the blocking member 40 is provided with a clearance portion 42, which is used to avoid interference with the rotation limiting structure 231 when the blocking member 40 rotates. The clearance portion 42 has a first surface 421 and a second surface 422 connected together. When the blocking member 40 rotates to the blocking position A, the first surface 421 of the clearance portion 42 abuts against the top area of ​​the rotation limiting structure 231 to limit the blocking member 40 from continuing to rotate. When the blocking member 40 rotates to the open position B, the second surface 422 of the clearance portion 42 abuts against the bottom area of ​​the rotation limiting structure 231 to limit the blocking member 40 from continuing to rotate. This ensures that the blocking member 40 maintains a preset tilt angle in the blocking position A and the open position B to ensure the surge blocking effect.

[0130] Meanwhile, by setting the rotation limiting structure 231, the rotation angle of the blocking member 40 can be limited within a preset range. When the blocking member 40 rotates toward the side of the lid module 20, it can be restricted by the rotation limiting structure 231, so that the blocking member 40 is relatively fixed with the lid module 20, thereby blocking dirt and suppressing the surge of dirt, preventing dirt from entering the suction device through the suction port 22, and reducing the risk of liquid damage to the suction device.

[0131] Please refer to Figure 2 and Figure 4 In some embodiments, when the stop member 40 is assembled inside the housing 10, the stop member 40 abuts against a portion of the circumferential outer wall of the inlet pipe 11 on the side adjacent to the inlet pipe 11, so that the stop member 40 is in the open position B.

[0132] Specifically, the stop member 40 rotates due to the inertial flow of dirt, thus switching between the stop position A and the open position B. When the stop member 40 is in the open position B, it abuts against the circumferential outer wall of the inlet pipe 11. This allows the inlet pipe 11 to mechanically limit the rotation angle of the stop member 40, ensuring that a dimensionally stable return channel is formed between the stop member 40 and the first side wall 12 when the stop member 40 is in the open position B.

[0133] Meanwhile, by making the stop member 40 abut against the sewage inlet pipe 11, the rotation angle of the stop member 40 can be limited, preventing the stop member 40 from rotating excessively under the impact of dirt, so that it cannot switch to the open position under the drive of dirt, thus ensuring the stability of the position switching of the stop member 40 under different working conditions.

[0134] In this embodiment, when the blocking member 40 switches to the blocking position A, the blocking member 40 can contact the first water-blocking member 23 to restrict the blocking member 40 to the blocking position A, so as to prevent the blocking member 40 from rotating excessively under the drive of dirt, so that it cannot switch to the open position B under the drive of dirt, thus ensuring the stability of the position switching of the blocking member 40 under different working conditions.

[0135] Please refer to Figure 1 and Figure 3 In some embodiments, the sewage tank 1 has a flat position. When the sewage tank 1 is in the flat position: the tank body 10 and the tank cover module 20 are arranged sequentially in a direction parallel to the surface to be cleaned 200, and the first side wall 12 is adjacent to the surface to be cleaned 200; the abutment 40 is configured to rotate under the drive of dirt in the sewage storage chamber 30.

[0136] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5When the cleaning device 100 is used lying flat, the wastewater tank 1 is also in a lying flat state. At this time, the first side wall 12 is close to the surface to be cleaned 200, and the dirt in the wastewater tank 1 will accumulate at the first side wall 12 under the action of gravity. If the user repeatedly pushes the cleaning device 100 to clean the surface to be cleaned 200 at this time, the dirt in the wastewater tank 1 will be pulled and pushed back during the user's use, moving back and forth towards or away from the tank cover module 20, causing a surge. When the surge height is high, the dirt will surge in the direction away from the surface to be cleaned 200, thereby pushing the blocking member 40 to cycle between the blocking position A and the open position B. In this way, the blocking member 40 can block the dirt, suppress the surge of dirt, and also block the dirt on the side of the blocking member 40 facing the dirt storage chamber 30 on the inner bottom wall, so as to reduce the risk of dirt entering the suction port 22. Thus, when the wastewater tank 1 is used in the cleaning equipment 100, the risk of dirt entering the suction device through the suction port 22 is reduced, thereby reducing the risk of liquid damage to the suction device.

[0137] Please refer to Figure 1 This application also provides a cleaning device 100, including a floor brush assembly 2, a body assembly 3, and a wastewater tank 1 as described in any of the above embodiments.

[0138] The sewage tank 1 has been described in the above embodiments and will not be repeated here.

[0139] Please refer to Figure 1 and Figure 2 One end of the body assembly 3 is rotatably connected to the floor brush assembly 2, and the other end of the body assembly 3 is provided with a handle 4. The floor brush assembly 2 is used to clean the surface 200 to be cleaned. The user can hold the handle 4 to push the cleaning device 100 to move, thereby cleaning the surface 200 to be cleaned.

[0140] Please refer to Figure 1 and Figure 4 The cleaning equipment 100 provided in this application embodiment has the above-mentioned sewage tank 1, and therefore has the beneficial effects of the above-mentioned sewage tank 1. During the process of assembling the tank cover module 20 into the tank body 10, the guide surface can guide the blocking part 40 to rotate to one side of the first side wall 12, so that the clearance notch 41 rotates to the assembly position that cooperates with the sewage inlet pipe 11, thereby providing users with intuitive installation feedback, so that users can clearly perceive whether the current assembly direction is correct, which not only protects the integrity of the sewage tank 1 structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the tank cover module 20 and the tank body 10.

[0141] Please refer to Figure 1This application also provides a cleaning system, including a base station and a cleaning device 100 as described in any of the above embodiments. The base station has a accommodating space, and the cleaning device 100 can be disposed within the accommodating space.

[0142] Please refer to Figure 1 and Figure 4 The cleaning system provided in this application embodiment has the aforementioned cleaning device 100, and therefore has the beneficial effects of the aforementioned cleaning device 100. During the process of assembling the cover module 20 into the tank body 10, the guide surface can guide the blocking part 40 to rotate to one side of the first side wall 12, so that the clearance notch 41 rotates to the assembly position that cooperates with the sewage inlet pipe 11, thereby providing the user with intuitive installation feedback, so that the user can clearly perceive whether the current assembly direction is correct, which not only protects the integrity of the sewage tank 1 structure, but also reduces the user's learning cost, improves the controllability of the assembly process and the user experience, and avoids the problem of surge suppression function failure caused by incorrect installation direction between the cover module 20 and the tank body 10.
