Description

Technical Field

[0001] This application relates to the field of wastewater tank technology, and more particularly to a wastewater tank, floor brush, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment has advantages such as being environmentally friendly, energy-saving, and highly efficient. As people become increasingly aware of the importance of household cleaning efficiency, cleaning equipment has gradually become widely used in daily production and life.

[0003] Currently, after cleaning equipment finishes its work, users typically empty the wastewater tank promptly to drain the wastewater and debris. The wastewater tank is an important component of the cleaning equipment, its main function being the collection of both dry and wet waste. When the wastewater tank is installed on the floor brush, its opening is usually located at the top for easy access by the user.

[0004] However, the cleaning process of the aforementioned sewage tank is rather cumbersome. Users need to open the top cover and flip the sewage tank to empty the garbage, which is inconvenient for users. Utility Model Content

[0005] This application provides a wastewater tank, a floor brush, cleaning equipment, and a cleaning system to solve the technical problem in the related art where the cleaning process of the wastewater tank is cumbersome, requiring users to open the top cover and flip the wastewater tank to empty the garbage, which is inconvenient for users.

[0006] In a first aspect, embodiments of this application provide a wastewater tank, which is installed on the floor brush of a cleaning device;

[0007] The sewage tank includes a tank body, the tank body having a receiving cavity and a wall surface surrounding the receiving cavity, the wall surface including a first side wall and a second side wall intersecting or parallel to the first side wall;

[0008] The wastewater tank also includes a handle on the first side wall and an opening on the second side wall that communicates with the receiving cavity.

[0009] The wastewater tank provided in this embodiment has an opening on the second side wall and a handle, allowing users to easily hold the tank and directly pour out wastewater and garbage through the opening without needing to flip the tank. This simplifies the cleaning process, improves operational convenience, and enables users to clean the wastewater tank quickly and efficiently, saving time and effort.

[0010] With the above settings, users can maintain their usual usage habits when the wastewater tank is mounted on the machine body, that is, holding the wastewater tank and emptying the wastewater through the opening without changing their usage habits. In addition, with the cleaning device equipped with a handheld part, users can open or close the opening as needed to facilitate cleaning the wastewater tank or emptying the wastewater inside.

[0011] In addition, by setting up the first sidewall, the second sidewall, and the cooperation between the openings, it is possible to ensure that waste is effectively collected and easily discharged, thereby improving the overall functionality of the wastewater tank and the cleaning effect of the cleaning equipment. This helps to maintain the long-term operation of the cleaning equipment and meet the growing demand of users for household cleaning efficiency.

[0012] Optionally, the wastewater tank described above may also include a closure for opening and closing the opening, the closure being rotatably connected to the second sidewall to open or close the opening;

[0013] Alternatively, the closure can be moved within the receiving cavity along the orientation of the opening to open or close the opening.

[0014] With the above setup, in actual use, when the user needs to empty the sewage tank, they can easily move the closure along the opening until the opening is exposed, allowing the sewage to drain smoothly. When it is necessary to close the opening, simply move the closure back to its original position.

[0015] Because of the rotating connection, users only need to hold the handle with one hand to secure the wastewater tank, and gently rotate the closure with the other hand to open or close the opening. This method eliminates the need for precise alignment or extra force to disassemble or install the closure, thus reducing the difficulty of cleaning the wastewater tank.

[0016] Optionally, in the above-mentioned sewage tank, the containing cavity includes a first chamber and a second chamber that are interconnected. The sewage tank also includes a solid-liquid separator located in the first chamber for filtering solid waste, while liquid waste enters the second chamber.

[0017] At least the first chamber communicates with the opening, and when the closure is moved and disposed within the receiving cavity, the second chamber is located on the side of the first chamber opposite to the opening;

[0018] The solid-liquid separation component includes a filter section connected to the sealing component. The filter section is used to filter solid contaminants, and the sealing component is used to drive the filter section into or out of the first chamber.

[0019] The system incorporates a first chamber connection opening, which is also the connection opening for the solid-liquid separator. Because this opening connects to the separator, it allows liquid waste to be filtered out while leaving solid waste. Therefore, users can remove the separator to empty the solid waste, thus cleaning the wastewater tank. Simultaneously, liquid waste flows to the second chamber, enabling the separated solid and liquid waste to be processed separately, preventing interference between them during treatment.

[0020] Furthermore, by installing a solid-liquid separator in the first chamber to filter out liquid contaminants, solid-liquid separation is achieved, facilitating cleaning for different types of contaminants and reducing the time required to clean the wastewater tank. The separated solid contaminants are stored in the first chamber, preventing them from clogging gas flow and ensuring the normal operation of the cleaning equipment.

[0021] With the above configuration, the enclosure effectively intercepts solid waste, storing it in the first chamber, while liquid waste flows to the second chamber after being filtered by the filter, achieving solid-liquid separation. This configuration avoids the mixing and accumulation of solid and liquid waste, facilitating separate treatment and improving the wastewater tank's efficiency in handling different types of waste.

[0022] Furthermore, when the filter needs cleaning or replacement, moving the closure allows the filter to detach from the first chamber, providing direct contact for easy cleaning or replacement. After maintenance, the closure is moved back, allowing the filter to re-enter the first chamber. This process is relatively simple, requiring no complex disassembly or assembly, saving time and effort, thus improving maintenance efficiency and ensuring the long-term operation of the cleaning equipment.

[0023] Optionally, in the above-mentioned sewage tank, the solid-liquid separation component further includes an isolation section, which is connected to the filter section and is located on the side of the filter section away from the enclosure.

[0024] When the filter section is located in the first chamber, the isolation section isolates the first chamber from the second chamber;

[0025] And / or, at least one of the isolation part and the sealing member is provided with a sealing member, and when the solid-liquid separation member is located in the first chamber, the sealing member abuts against the inner wall of the first chamber.

[0026] With the above setup, the isolation section can effectively prevent solid waste from entering the second chamber, avoid mixing solid waste with liquid waste, and facilitate the subsequent separate treatment of different types of waste.

[0027] In addition, the seals prevent dirt from leaking directly between the filter section and the inner wall of the first chamber, ensuring that dirt can be fully filtered by the filter section.

[0028] Optionally, in the aforementioned wastewater tank, the floor brush has a wastewater inlet, the tank body has a wastewater inlet channel, and the wastewater inlet channel is connected to the wastewater inlet of the floor brush.

[0029] The output side of the sewage inlet channel is connected to the first chamber, and the output side of the sewage inlet channel faces the opening.

[0030] When the cleaning equipment is working, the floor brush sucks up the dirt and enters the dirt inlet channel through the dirt inlet, and then directly into the first chamber. Because the output side faces the opening, the direction of dirt discharge corresponds to the position of the opening, which helps the dirt to enter the wastewater tank.

[0031] Optionally, in the aforementioned wastewater tank, the wastewater tank further includes a drive structure, the input end of which is located at the bottom of the first chamber, to transport the liquid in the first chamber to the second chamber;

[0032] The enclosure also has a negative pressure port, which is located at the top of the first chamber;

[0033] A cavity is formed between the solid-liquid separator and the first chamber. The solid-liquid separator also includes a first sealing part that divides the cavity into an upper cavity and a lower cavity along the height direction. The first sealing part is used to separate the drive structure from the negative pressure port. The negative pressure port is connected to the upper cavity, and the lower cavity is connected to the input end of the drive structure.

[0034] With the above configuration, the first sealing part can separate the drive structure from the negative pressure port, ensuring that the drive structure is not disturbed by the airflow at the negative pressure port when extracting liquid waste, thereby improving the working efficiency of the drive structure.

[0035] In addition, the first sealing section can also prevent dirt from being directly carried into the negative pressure port by the airflow, causing blockage of the negative pressure port, so as to ensure the normal operation of the cleaning equipment.

[0036] Optionally, in the aforementioned wastewater tank, the solid-liquid separation component further includes a second sealing part, which is connected between the isolation part and the sealing component, and is also connected to the first sealing part.

[0037] At least a portion of the second sealing portion is spaced apart from the top wall of the first chamber, so that the negative pressure port communicates with the first chamber corresponding to the filter portion.

[0038] And / or, the solid-liquid separation component further includes a third sealing part, which is disposed corresponding to the negative pressure port and connected to the second sealing part; the third sealing part extends toward the isolation part and exceeds the end of the negative pressure port toward the isolation part.

[0039] When the cleaning equipment is running, the negative pressure source draws airflow through the negative pressure port. The airflow can smoothly pass through the connection path between the second sealing part and the top wall of the first chamber, thereby ensuring the flow of airflow in the sewage tank. This allows the airflow to effectively carry the dirt into the sewage tank and complete the filtration and separation process.

[0040] During the operation of the cleaning equipment, the airflow and the movement of waste within the sewage tank can easily cause impact and vibration to the filter section, partition section, first sealing section, or second sealing section. The connection between the third sealing section and the second sealing section provides mutual support between the different parts of the solid-liquid separation component, avoiding the risk of displacement or deformation of the solid-liquid separation component. The above configuration ensures airflow in the drive structure and guarantees the extraction function of the drive structure.

[0041] In the aforementioned sewage tank, optionally, when the closure is rotatably connected to the second side wall, the opening connects the first chamber and the second chamber, with the second chamber located above the first chamber;

[0042] The wastewater tank also includes a drive structure, the input end of which is located at the bottom of the first chamber, and the output end of which is located in the second chamber;

[0043] The solid-liquid separator is located upstream of the output end of the drive structure.

[0044] The above-described vertically distributed first and second chambers create a compact internal structure for the wastewater tank, improving space utilization. Furthermore, the openings facilitate easy cleaning of both chambers. Users can easily access the waste within both chambers, simplifying maintenance and saving time and effort. Additionally, this design prevents liquid waste from accumulating at the bottom of the first chamber, reducing the risk of odors and bacterial growth.

[0045] In the aforementioned sewage tank, optionally, the closure is rotatably connected to the second side wall via a rotating shaft, and a torsion spring is sleeved on the rotating shaft.

[0046] With the above setup, when cleaning the wastewater tank, users only need to hold the handle with one hand to stabilize the tank, and gently rotate the closure with the other hand to open or close the opening. The torsion spring design allows the closure to automatically return to its original position after being rotated under force, eliminating the need for additional operation, simplifying the usage process, reducing operational difficulty, and making it especially suitable for one-handed operation, thus improving the user experience.

[0047] In the aforementioned sewage tank, optionally, the first sidewall is the top of the sewage tank, and the second sidewall intersects with the first sidewall; the handle is configured to be close to the closure so that the user can open the closure while holding the handle, and the angle between the closure and the horizontal direction is not less than 60°.

[0048] An angle of at least 60° ensures the closure remains stable when open, allowing users to easily rotate the closure to open or close the opening with one hand while holding the handle with the other, simplifying the operation and improving ease of use. Furthermore, the at least 60° angle facilitates the smooth discharge of waste, preventing residue or blockage caused by improper closure angles and improving cleaning efficiency.

[0049] Secondly, this application embodiment also provides a sewage tank, which is disposed on the floor brush of a cleaning device, and the floor brush has a groove for placing the sewage tank;

[0050] The wastewater tank includes a tank body, the tank body having a receiving cavity and a wall surface surrounding the receiving cavity, the wall surface having an opening communicating with the receiving cavity; when the wastewater tank is placed on the floor brush, the opening corresponds to the inner sidewall of the groove in the horizontal direction.

[0051] In the above-mentioned sewage tank, optionally, the wall surface includes a first side wall and a second side wall, the first side wall is disposed on the side away from the bottom wall of the groove, and the second side wall is disposed corresponding to the inner side wall of the groove;

[0052] The wastewater tank also includes a handle disposed on the first side wall, and a closure for opening and closing the opening, which is disposed on the second side wall.

[0053] In the aforementioned wastewater tank, optionally, the handle protrudes from the tank wall; and / or, the handle is a groove disposed on the tank wall; and / or, the top of the handle is not higher than the top of the floor brush.

[0054] Thirdly, this application embodiment also provides a wastewater tank, which is installed on the floor brush of a cleaning device. The floor brush has a wastewater inlet. The wastewater tank includes a tank body with a wastewater inlet channel. The input side of the wastewater inlet channel is connected to the wastewater inlet of the floor brush. The tank body has a receiving cavity and a wall surrounding the receiving cavity. The wall has an opening connecting the receiving cavity and a negative pressure port. The output side of the wastewater inlet channel is connected to the receiving cavity. The negative pressure port is connected to a negative pressure source. The opening is used to empty the waste in the receiving cavity.

[0055] Optionally, in the aforementioned wastewater tank, the floor brush has a groove for placing the wastewater tank; the opening corresponds to the inner wall of the groove in the horizontal direction.

[0056] And / or, the negative pressure port is higher than the sewage inlet channel;

[0057] And / or, the opening, the negative pressure port, and the sewage inlet channel are located on different sides of the wall.

[0058] Optionally, in the aforementioned sewage tank, the wall surface includes a first side wall and a second side wall, the first side wall being the top of the sewage tank, the second side wall being the side of the sewage tank, a handle being disposed on the first side wall, and the opening being disposed on the second side wall.

[0059] Fourthly, embodiments of this application also provide a floor brush, including a roller brush and the aforementioned wastewater tank, wherein the roller brush is located on the front side of the wastewater tank.

[0060] Fifthly, embodiments of this application also provide a cleaning device, including a body and the aforementioned floor brush, wherein the floor brush is connected to the body.

[0061] Sixthly, embodiments of this application also provide a cleaning system, including the aforementioned cleaning equipment and a base station or base station that cooperates with it.

[0062] The wastewater tank, floor brush, cleaning equipment, and cleaning system provided in this application embodiment, by installing a wastewater tank on the floor brush of the cleaning equipment, with a handle on the first side wall and an opening on the second side wall connecting to the receiving cavity, not only allows users to hold the wastewater tank and directly pour out wastewater and garbage through the opening without having to flip the wastewater tank, simplifying the cleaning steps, improving operational convenience, and saving time and effort; but also allows users to maintain their usage habits when the wastewater tank is installed on the machine body, that is, to hold the wastewater tank and pour out the waste through the opening without having to change their usage habits.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0091] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0092] 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, and 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.

[0093] In a first aspect, embodiments of this application provide a cleaning system, including a base station and cleaning equipment, wherein the cleaning equipment can be placed on the base station.

[0094] Understandably, after cleaning the surface, the cleaning equipment can be placed on a base station for positioning, charging, self-cleaning, drying, and water supply / discharge. The base station has designated placement areas for the cleaning equipment, enabling its accurate positioning. A charging port is provided on the base station for charging the equipment. Water inlet and drain pipes can be installed on the base station to fill the clean water tank and drain the waste water tank. A drying device can be installed on the base station to dry the cleaned equipment.

[0095] It should be noted that base stations generally need to be fixed to the surface to be cleaned in order to support the operation of the cleaning equipment.

[0096] It is understandable that cleaning equipment can be of different types. For example, cleaning equipment can be a robot vacuum cleaner, a robot mop, a robot vacuum and mop combo, or a floor scrubber, etc. Different types of cleaning equipment all have corresponding base stations.

[0097] The following explanation uses a floor scrubber as an example of cleaning equipment.

[0098] Reference Figure 1Secondly, this application also provides a cleaning device 20, including a floor brush 21 and a body (not shown in the figure), the floor brush 21 being connectable to the body. A negative pressure source and a battery pack are disposed within the body. The negative pressure source can be a suction fan used to provide suction power. The negative pressure source is located at the lower part of the body, close to the floor brush 21, and thus close to the wastewater tank 10, thereby shortening the distance between the negative pressure source and the wastewater tank 10 and reducing suction power loss.

[0099] Thirdly, this application embodiment also provides a floor brush 21, including a roller brush and a wastewater tank 10, with the roller brush located at the front of the wastewater tank 10. The floor brush 21 has a wastewater inlet, and the wastewater tank 10 is disposed on the floor brush 21. When the floor brush 21 is working on the surface to be cleaned, dirt can enter the wastewater tank 10 through the wastewater inlet, that is, the wastewater tank 10 is used to collect the dirt sucked up by the floor brush 21 through the wastewater inlet. The wastewater tank 10 has a receiving cavity 110 for storing dirt.

[0100] Fourthly, embodiments of this application also provide a sewage tank 10.

[0101] In some embodiments, the floor brush 21 has a recess 22 for placing the wastewater tank 10. It is understood that by placing the wastewater tank 10 on the floor brush 21, firstly, the loss of wastewater and debris during transport can be reduced, improving cleaning efficiency and ensuring that dirt on the surface to be cleaned can be collected quickly and effectively. Secondly, since the wastewater tank 10 is close to the floor brush 21, it is convenient for users to directly empty the wastewater and debris after cleaning, reducing operation steps and cleaning time.

[0102] It should be noted that the groove 22 has an opening for the sewage tank 10 to be placed. The opening can be made on the side of the floor brush 21, or on the bottom surface of the floor brush 21.

[0103] The cleaning device 20 provided in this embodiment has a wastewater tank 10 on the floor brush 21. Compared to related technologies where the wastewater tank 10 is located on the machine body, this lowers the center of gravity of the machine, making it easier for users to operate. It also reduces wastewater and debris loss during transport, improving cleaning efficiency and ensuring that dirt on the surface to be cleaned is collected quickly and effectively. Furthermore, because the wastewater tank 10 is close to the floor brush 21, users can easily empty the wastewater and debris directly after cleaning, reducing operation steps and cleaning time.

[0104] In some embodiments, the wastewater tank 10 includes a tank body 100 having a receiving cavity 110 for storing waste.

[0105] It is understood that the shape of the receiving cavity 110 can be arbitrary. For example, the receiving cavity 110 can be a cuboid cavity, a cylindrical cavity, or a spherical cavity. The embodiments of this application do not limit the specific shape of the receiving cavity 110, nor are they limited to the above examples.

[0106] The following explanation uses the rectangular cavity 110 as an example.

[0107] The housing 100 also has a wall 120 that surrounds and forms the receiving cavity 110.

[0108] In some embodiments, the wall surface 120 has an opening 130 communicating with the receiving cavity 110. When the wastewater tank 10 is placed on the floor brush 21, the opening 130 corresponds to the inner sidewall of the groove 22 in the horizontal direction X. In this way, the wastewater tank 10 can be placed in the groove 22 through the opening 130, and the waste in the wastewater tank 10 can be poured out through the opening 130.

[0109] Understandably, users can maintain their usual habits of using the wastewater tank 10, that is, holding the wastewater tank 10 and emptying the waste through the opening 130 on one side, without having to change their usage habits, which is convenient for users.

[0110] In some embodiments, the wall 120 includes a first sidewall 121 and a second sidewall 122 that intersects with or is parallel to the first sidewall 121. Further, the first sidewall 121 and the second sidewall 122 may refer to two adjacent wall surfaces 120 of the cuboid cavity, in which case the first sidewall 121 and the second sidewall 122 intersect; in another example, the first sidewall 121 and the second sidewall 122 may also refer to two opposite wall surfaces of the cuboid cavity, in which case the first sidewall 121 and the second sidewall 122 are parallel.

[0111] In some embodiments, the wall surface 120 includes a first sidewall 121 and a second sidewall 122. The first sidewall 121 is disposed on the side away from the bottom wall of the groove 22, and the second sidewall 122 is disposed on the inner sidewall of the groove 22. It can be understood that the first sidewall 121 refers to the side opposite to the bottom wall, and the second sidewall 22 can be any wall surface of the groove 22.

[0112] Understandably, users can maintain their usual habits of using the wastewater tank 10, that is, holding the wastewater tank 10 and emptying the waste through the opening 130 on one side, without having to change their usage habits, which is convenient for users.

[0113] In some embodiments, the wastewater tank 10 further includes a handle 600 disposed on the first sidewall 121. The handle 600 is for a user to hold, so that the user can pick up the wastewater tank 10 by holding the handle 600, making it convenient for the user to use.

[0114] It should be noted that the hand-held part 600 does not have to be a specific entity; any part of the sewage tank 10 that can be held by hand can be called the hand-held part 600.

[0115] In some embodiments, the handle 600 is provided protruding from the wall of the tank 100. That is, the handle 600 may be formed by extending from the wall of the tank 100, so that the user can directly grasp the handle 600 from the outside and easily pick up the sewage tank 10.

[0116] In some embodiments, the handle 600 is a groove provided on the wall of the housing 100. That is, the handle 600 is in the form of a groove, which is formed on the wall of the housing 100, so that the handle 600 and the housing 100 are integrated, which can improve the connection strength between the handle 600 and the housing 100.

[0117] In some embodiments, the top of the handle 600 is not higher than the top of the floor brush 21. That is, the highest point of the handle 600 does not exceed the highest point of the floor brush 21. For example, during the operation of the cleaning equipment, an excessively high handle 600 will protrude from the floor brush 21, thereby affecting the floor brush 21's ability to access areas with height requirements, such as under beds and sofas, and thus affecting the normal operation of the cleaning equipment.

[0118] In some embodiments, the wastewater tank 10 further has an opening 130 communicating with the receiving cavity 110, the opening 130 being disposed on the second sidewall 122. It is understood that by providing the opening 130 communicating with the receiving cavity 110, wastewater from the wastewater tank 10 can be dumped through the opening 130.

[0119] Furthermore, the wastewater tank 10 also includes a closure 200, which is used to open and close the opening 130. It is understood that the opening 130 connects to the receiving cavity 110, which is used to contain waste. To ensure the sealing performance of the wastewater tank 10, the material of the closure 200 can be plastic, metal, etc. This application embodiment does not limit the specific material of the closure 200, nor is it limited to the above examples.

[0120] In some embodiments, the closure method of the closure member 200 may also be multiple.

[0121] For example, the closure 200 may enter or exit the receiving cavity 110. When the closure 200 enters the receiving cavity 110, the closure 200 may cover the opening 130 and thus close the opening 130; when the closure 200 exits the receiving cavity 110, the closure 200 may expose the opening 130 and thus open the opening 130.

[0122] In another example, the closure 200 is movably connected to the housing 100. When the closure 200 is moved to the position of closing the opening 130, the closure 200 closes the opening 130; when the closure 200 is moved to the position of exposing the opening 130, the closure 200 opens the opening 130.

[0123] Furthermore, the closure 200 can be rotatably connected to the second side wall 122 of the housing 100, that is, the closure 200 can change the angle relative to the second side wall 122 to change the exposure degree of the opening 130, thereby opening or closing the opening 130.

[0124] With the above-described configuration, the opening 130 of the wastewater tank 10 in the traditional cleaning device 20 is located at the top. Users need to open the cover and flip the wastewater tank 10 to empty it, a cumbersome process. However, the cleaning device 20 provided in this embodiment has the opening 130 located on the second side wall 122 and includes a handle 600. Users can easily hold the wastewater tank 10 and directly empty the wastewater through the opening 130 without flipping the tank. This simplifies the cleaning process, improves operational convenience, and allows users to quickly and efficiently clean the wastewater tank 10, saving time and effort.

[0125] It should be noted that, with the above settings, users can maintain their usage habits when the sewage tank 10 is installed on the machine body, that is, they can hold the sewage tank 10 and pour out the sewage through the opening 130 without changing their usage habits.

[0126] In addition, the cleaning device 20 equipped with a handheld part 600 allows the user to open or close the opening 130 as needed, so as to clean the sewage tank 10 or empty the sewage tank 10.

[0127] In addition, by setting up the first sidewall 121, the second sidewall 122, and the cooperation between the opening 130 and the closure 200, it is possible to ensure that the waste is effectively collected and easily discharged, thereby improving the overall functionality of the wastewater tank 10 and the cleaning effect of the cleaning equipment 20, which helps to maintain the long-term operation of the cleaning equipment 20 and meet the growing demand of users for household cleaning efficiency.

[0128] Reference Figure 2 and Figure 5 As an optional implementation, the housing 100 has a sewage inlet channel 140 and a negative pressure port 150.

[0129] Specifically, the inlet channel 140 is used to connect to the inlet of the floor brush, and the negative pressure port 150 is used to connect to the negative pressure source of the cleaning equipment 20. That is, under the action of the negative pressure source of the machine body, the dirt is sucked up by the airflow by the cleaning equipment 20. The dirt and airflow can enter the housing 100 through the inlet and the inlet channel 140 in sequence and stay in the wastewater tank 10. The airflow can enter the housing 100 through the inlet and the inlet channel 140 in sequence and flow to the negative pressure source through the negative pressure port 150 to complete the airflow circulation.

[0130] In some embodiments, the negative pressure port 150 is higher than the sewage inlet channel 140.

[0131] Thus, when the cleaning equipment 20 is operating, due to the negative pressure source, dirt and airflow enter from the dirt inlet of the floor brush, and then sequentially pass through the dirt inlet channel 140 into the housing 100. Simultaneously, the airflow also flows towards the negative pressure source through the negative pressure port 150. The design of the negative pressure port 150 being higher than the dirt inlet channel 140 helps to facilitate the separation of dirt within the housing 100 during the airflow suction process, utilizing gravity and airflow flow principles. This height difference effectively reduces the possibility of dirt being carried back out of the housing 100 when the airflow passes through the negative pressure port 150, improving the cleaning efficiency of the cleaning equipment 20, and also helps protect the negative pressure source, preventing damage from dirt directly entering the negative pressure source.

[0132] In some embodiments, the opening 130, the negative pressure port 150, and the sewage inlet channel 140 are located on different surfaces of the wall. That is, the distribution of the opening 130, the negative pressure port 150, and the sewage inlet channel 140 on the wall of the housing 100 is separate from each other, and each is located on a different wall surface.

[0133] For example, opening 130 may be located at the front of housing 100 for easy user operation or to cooperate with other components; negative pressure port 150 may be located on the side, close to the negative pressure source of cleaning device 20; and wastewater inlet channel 140 may be located at the bottom or other side for connection to the wastewater inlet of floor brush. These different wall surface distributions ensure that the various functional interfaces of housing 100 do not interfere with each other.

[0134] Reference Figure 3 and Figure 6 In some embodiments, the receiving cavity 110 includes a first chamber 111 and a second chamber 112.

[0135] It is understood that waste may include sewage liquid and solid waste. In order to facilitate users to clean the sewage tank 10, the first chamber 111 and the second chamber 112 may be a solid chamber and a liquid chamber for collecting solid waste and sewage liquid, respectively.

[0136] In some embodiments, the first chamber 111 and the second chamber 112 are connected, meaning that the solid chamber and the liquid chamber are connected. Along the suction airflow direction of the negative pressure source, the second chamber 112 is located downstream of the first chamber 111, meaning that the airflow first enters the first chamber 111 and then flows from the first chamber 111 to the second chamber 112.

[0137] Furthermore, the solid-liquid separator 300 is used to achieve solid-liquid separation. For example, the solid-liquid separator 300 is installed within the first chamber 111.

[0138] It is understood that the solid-liquid separator 300 can be one or more of the following structures or devices with a certain pore size: filter screen, filter plate, centrifugal separator, etc. In this way, the solid-liquid separator 300 can filter solid waste transported from the sewage inlet channel 140 into the first chamber 111, and then the liquid waste enters the second chamber 112, thereby achieving the separation of solid waste and liquid waste, which facilitates subsequent separate treatment and can improve the sewage treatment efficiency and effect of the sewage tank 10.

[0139] Specifically, when the cleaning equipment 20 is working, the floor brush sucks up the waste (including solid waste and liquid waste) through the waste inlet and enters the first chamber 111 of the wastewater tank 10. The solid-liquid separator 300 utilizes its own structural characteristics, such as the pore size of the filter screen and the rotation speed of the centrifuge, to trap solid waste on one side or surface of the solid-liquid separator 300, while liquid waste flows through the pores of the solid-liquid separator 300 or under the action of centrifugal force to the other side and flows to the downstream second chamber 112, thereby achieving solid-liquid separation.

[0140] Reference Figure 3 and Figure 8 Specifically, at least the first chamber 111 is connected to the opening 130, that is, the solid-liquid separator 300 is connected to the opening 130. Since the opening 130 is connected to the solid-liquid separator 300, the solid-liquid separator 300 can filter out liquid waste while leaving solid waste. Therefore, the user can remove the solid-liquid separator 300 to empty the solid waste, thereby cleaning the wastewater tank 10. Simultaneously, the liquid waste flows to the second chamber 112, allowing the solid-liquid separated waste to be processed separately, avoiding interference between solid and liquid waste during processing.

[0141] Furthermore, by installing a solid-liquid separator 300 in the first chamber 111 to filter out liquid contaminants, solid-liquid separation is achieved, making it easier for users to clean different types of contaminants and shortening the time required for users to clean the wastewater tank 10. The separated solid contaminants are stored in the first chamber 111, preventing them from clogging gas flow and ensuring the normal operation of the cleaning equipment 20 and the cleaning system.

[0142] In some embodiments, a concealed handle 800 is provided on the side of the closure 200 away from the solid-liquid separator 300. The concealed handle 800 means that when not in use, the handle 800 can be close to the outer surface of the closure 200 to achieve concealment.

[0143] For example, the handle 800 can be built into or embedded in the closure 200, so that the handle 800 does not protrude from the surface of the closure 200 when not in use, thus achieving concealment. The above configuration avoids the snagging or collision problems that may occur with traditional exposed handles 800, thereby improving the user's operating experience and enhancing convenience and safety.

[0144] In addition, the concealed handle 800 reduces space occupation, making the wastewater tank 10 more compact when stored or used. At the same time, the concealed handle 800 makes the surface of the closure 200 smoother, which can improve the aesthetics of the wastewater tank 10 and the cleaning equipment 20, conforming to the minimalist aesthetics of modern home appliances.

[0145] In some embodiments, the two ends of the handle 800 are connected to the side of the closure 200 away from the box 100, and at least the middle portion of the handle 800 is elastic so that the handle 800 can fit against the closure 200.

[0146] Specifically, the two ends of the handle 800 are connected to the side of the closure 200 away from the tank body 100, ensuring that the user can easily grasp the handle 800 and optimize the operating experience. The middle part of the handle 800 is elastic and can fit the closure 200 to avoid taking up space, making the sewage tank 10 more compact when stored or used, while maintaining the flatness of the surface of the closure 200 and improving the appearance.

[0147] For example, the concealed handle 800 can be made of an elastic strip of fabric, with both ends of the strip connected to the closure 200 on the side opposite to the box body 100.

[0148] In some other embodiments, the closure 200 has a receiving groove on the side opposite to the housing 100, and the handle 800 is located in the receiving groove. The receiving groove provides storage space for the handle 800. In this way, the handle 800 will not protrude from the surface of the closure 200 when not in use, without occupying the space above the top cover, while maintaining the flatness of the surface of the closure 200, which can improve the aesthetics of the sewage tank 10 and the cleaning equipment 20.

[0149] One end of the handle 800 is connected to the closure 200 via a torsion spring, allowing the handle 800 to pop out easily when in use and retract automatically when not in use, thus optimizing the user's operating experience.

[0150] In addition, the torsion spring can enhance the structural strength of the handle 800, enabling it to withstand greater tensile forces during use and reducing the risk of damage caused by external impacts.

[0151] The following are examples of different closure components 200.

[0152] Reference Figures 1-4 As an optional implementation, the closure 200 is movably disposed within the receiving cavity 110 along the orientation of the opening 130 to open or close the opening 130.

[0153] With the above-described configuration, in actual use, when the user needs to empty the wastewater tank 10, the closure 200 can be easily moved along the opening 130 until the opening 130 is exposed, allowing the waste to drain smoothly. When it is necessary to close the opening 130, simply move the closure 200 back to its original position. Because the closure 200 can be flexibly adjusted according to actual needs, unlike fixed closures which occupy excessive space, this helps improve the volume utilization rate of the wastewater tank 10, meeting the user's need for large-capacity wastewater collection from the cleaning equipment 20, and enhancing the overall cleaning efficiency and practicality of the cleaning equipment 20.

[0154] In some embodiments, the second chamber 112 is located on the side of the first chamber 111 opposite to the opening 130, that is, the opening 130, the first chamber 111 and the second chamber 112 are arranged and connected in sequence, which can ensure that the waste is smoothly transported from the clean area to the wastewater tank 10 and collected and separated.

[0155] With the above-described configuration, users can directly access and clean the solid waste in the first chamber 111 through the opening 130, and the liquid waste in the second chamber 112 can also be easily discharged. Thus, users do not need to disassemble parts or flip the wastewater tank 10 to empty it; for example, they do not need to open the top cover and flip the tank 100 to empty it as in the traditional method. They can directly clean the first chamber 111 through the opening 130 and discharge the liquid from the second chamber 112, reducing the difficulty of cleaning.

[0156] Furthermore, the solid-liquid separation component 300 includes a filter section 310, which, as described above, refers to the aforementioned filter screen structure. The filter section 310 is connected to the sealing member 200. The filter section 310 is used to filter solid contaminants, and the sealing member 200 is used to drive the filter section 310 into or out of the first chamber 111.

[0157] With the above configuration, the enclosure 200 can effectively intercept solid waste, storing it in the first chamber 111, while liquid waste flows to the second chamber 112 after being filtered by the filter section 310, thus achieving solid-liquid separation. This configuration avoids the mixing and accumulation of solid and liquid waste, facilitating separate treatment and improving the treatment efficiency of the wastewater tank 10 for different types of waste.

[0158] Furthermore, when the filter section 310 needs cleaning or replacement, moving the closure 200 allows the filter section 310 to detach from the first chamber 111, enabling direct contact with the filter section 310 for easy cleaning or replacement. After maintenance, the closure 200 is moved back, allowing the filter section 310 to re-enter the first chamber 111. This process is relatively simple, requiring no complex disassembly or assembly, saving time and effort, thereby improving maintenance efficiency and ensuring the long-term operation of the cleaning equipment 20.

[0159] Reference Figure 3 In some embodiments, at least one of the isolation section 320 and the sealing member 200 is provided with a sealing member 700. When the solid-liquid separation member 300 is located in the first chamber 111, the sealing member 700 abuts against the inner wall of the first chamber 111, which can prevent dirt from leaking directly between the filter section 310 and the inner wall of the first chamber 111, and ensure that dirt can be fully filtered by the filter section 310.

[0160] In some embodiments, the seal 700 includes a plurality of sealing protrusions 710 spaced apart along the orientation of the opening 130, such that when the closure 200 is installed or removed from the filter section 310, the sealing protrusions 710 can sequentially contact or separate from the inner wall of the first chamber 111 to provide guidance for the closure 200, thereby simplifying the installation and removal process of the filter section 310 and reducing maintenance costs.

[0161] It is understood that the number of sealing protrusions 710 can be arbitrary; for example, the number of sealing protrusions 710 can be two, three, four, etc. This application embodiment does not limit the specific number of sealing protrusions 710, nor is it limited to the above examples.

[0162] Furthermore, to prevent the sealing protrusion 710 from impacting the inner wall of the first chamber 111, the sealing protrusion 710 can be made of a flexible material, such as rubber. This application embodiment does not specifically describe the material of the sealing protrusion 710.

[0163] Reference Figure 3 and Figure 4 In some embodiments, the solid-liquid separator 300 further includes an isolation section 320, which is connected to the filter section 310 and is located on the side of the filter section 310 away from the closure section 200.

[0164] When the filter section 310 is located in the first chamber 111, the isolation section 320 isolates the first chamber 111 from the second chamber 112. The isolation section 320 can effectively prevent solid waste from entering the second chamber 112, avoid solid waste from mixing with liquid waste, and facilitate the subsequent separate treatment of different types of waste.

[0165] It is understandable that the solid-liquid separator 300 and the sealing component 200 are integrated into one unit. This integrated design enhances the connection stability between the solid-liquid separator 300 and the sealing component 200, thereby ensuring the stable operation of the cleaning equipment 20.

[0166] Reference Figure 4 In some embodiments, the output side of the sewage inlet channel 140 is opened on the isolation section 320, and the output side of the sewage inlet channel 140 faces the opening 130.

[0167] When the cleaning equipment 20 is working, the dirt sucked up by the floor brush enters the dirt inlet channel 140 through the dirt inlet, and is then discharged from the output side of the isolation section 320, directly into the first chamber 111. Since the output side faces the opening 130, the discharge direction of the dirt corresponds to the position of the opening 130, which helps the dirt to enter the wastewater tank 10.

[0168] In addition, by setting the outlet of the sewage inlet channel 140 in the isolation section 320, no additional connecting parts are required. The above-mentioned integrated design can reduce production costs and enhance structural stability.

[0169] Reference Figure 2 and Figure 4 In some embodiments, the wastewater tank 10 further includes a drive structure 400, the input of which is located at the bottom of the first chamber 111 to transport liquid in the first chamber 111 to the second chamber 112.

[0170] It is understood that the driving component can be of different types of structures. For example, the driving component can be a motor providing positive pressure, in which case the driving component can be disposed within the first chamber 111 and provide pressure to drive liquid into the second chamber 112, such as a pump body providing compressed air, nitrogen, or other compressed gas. Another example is a motor providing negative pressure, such as a vacuum pump, in which case the driving component can be disposed within the second chamber 112 and provide suction to draw liquid into the second chamber 112. Yet another example is a liquid pump, which can draw liquid from the first chamber 111 and deliver it to the second chamber 112. The foregoing embodiments can be combined in any way.

[0171] The following explanation uses a liquid pump, whose driving component is a liquid pump, as an example.

[0172] Reference Figure 5A cavity 113 is formed between the solid-liquid separator 300 and the first chamber 111. The solid-liquid separator 300 also includes a first sealing part 330 that divides the cavity 113 into an upper cavity 1131 and a lower cavity 1132 along the height direction Z. The first sealing part 330 is used to separate the drive structure 400 from the negative pressure port 150. At this time, the negative pressure port 150 is connected to the upper cavity 1131, and the input end of the drive structure 400 is connected to the lower cavity 1132.

[0173] With the above settings, the first sealing part 330 can separate the drive structure 400 from the negative pressure port 150, ensuring that the liquid contaminants filtered by the solid-liquid separator 300 can be extracted by the drive structure 400, while ensuring that the liquid contaminants are not disturbed by the airflow at the negative pressure port 150, thereby improving the working efficiency of the drive structure 400.

[0174] In addition, the first sealing part 330 can also prevent dirt from being directly carried into the negative pressure port 150 by the airflow, causing blockage of the negative pressure port 150, so as to ensure the normal operation of the cleaning equipment 20.

[0175] It should be noted that the filter section 310 is lower than the first sealing section 330 and higher than the bottom wall of the first chamber 111. That is, the filter section 310 is located between the first sealing section 330 and the bottom wall of the first chamber 111. The above arrangement enables the filter section 310 to effectively intercept dirt in the first chamber 111, while reserving enough space for the drive structure 400 to absorb liquid dirt.

[0176] In this way, the first sealing part 330 can form two independent cavities, namely the upper cavity 1131 and the lower cavity 1132. The upper cavity 1131 corresponds to the negative pressure port 150, and the lower cavity 1132 corresponds to the input end of the drive structure 400, so that the drive structure 400 and the negative pressure port 150 can work independently and avoid interference.

[0177] Reference Figure 3 and Figure 4 In some embodiments, the solid-liquid separator 300 further includes a second sealing portion 340, which is connected between the isolation portion 320 and the sealing member 200, and is also connected to the first sealing portion 330. It is understood that the second sealing portion 340, by connecting the isolation portion 320 and the sealing member 200, can enhance the separating function of the isolation portion 320.

[0178] At least a portion of the second sealing part 340 is spaced apart from the top wall of the first chamber 111, so that the negative pressure port 150 connects to the portion of the first chamber 111 corresponding to the filter part 310. Thus, when the cleaning equipment 20 is running, the negative pressure source draws airflow through the negative pressure port 150, allowing the airflow to smoothly pass through the connection path between the second sealing part 340 and the top wall of the first chamber 111, thereby ensuring airflow within the wastewater tank 10 and enabling the airflow to effectively carry dirt into the wastewater tank 10 and complete the filtration and separation process.

[0179] In addition, the aforementioned connection design can prevent airflow obstruction caused by blockage, maintain the normal operation of the negative pressure source, and thus ensure the suction capacity of the cleaning equipment 20.

[0180] It should be noted that the connection between the second sealing part 340 and the first sealing part 330, as well as the isolation part 320 and the sealing member 200, can also enhance the structural strength of the solid-liquid separation member 300.

[0181] Specifically, during the operation of the cleaning equipment 20, the airflow and waste flow within the wastewater tank 10 will impact and vibrate the filter section 310, the partition section, or the first sealing section 330. The connection of the second sealing section 340 enables different parts of the solid-liquid separator 300 to support each other, avoiding the risk of displacement or deformation of the solid-liquid separator 300. The above arrangement ensures the airflow of the drive structure 400 and guarantees the extraction function of the drive structure 400.

[0182] Reference Figure 3 and Figure 4 In some embodiments, the solid-liquid separator 300 further includes a third sealing portion 350, which is disposed corresponding to the negative pressure port 150 and connected to the second sealing portion 340. The third sealing portion 350 extends toward the isolation portion 320 and exceeds the end of the negative pressure port 150 facing the isolation portion 320. It should be noted that the end refers to the position in the negative pressure port 150 closest to the isolation portion 320. In this way, along the opening direction of the negative pressure port 150, the projection of the third sealing portion 350 on the housing 100 can cover the negative pressure port 150, so as to ensure that the airflow cannot flow directly to the negative pressure port 150 through the third sealing portion 350.

[0183] Understandably, when the cleaning equipment 20 is running, the negative pressure source draws airflow through the negative pressure port 150, and the third sealing part 350 can effectively ensure that the airflow carries dirt through the filter part 310 for filtration, so that the filter part 310 intercepts solid dirt, and finally the airflow flows to the negative pressure port 150, thereby completing the airflow circulation.

[0184] It should be noted that during the operation of the cleaning equipment 20, the airflow and the movement of waste within the wastewater tank 10 can easily cause impact and vibration to the filter section, the partition section, the first sealing section 330, or the second sealing section 340. The connection between the third sealing section 350 and the second sealing section 340 provides mutual support between different parts of the solid-liquid separator 300, avoiding the risk of displacement or deformation of the solid-liquid separator 300. The above arrangement ensures the airflow of the drive structure 400 and guarantees the extraction function of the drive structure 400.

[0185] Reference Figures 6-10 As an alternative implementation, the closure 200 is rotatably connected to the second sidewall 122 to open or close the opening 130.

[0186] Because of the rotating connection, the user only needs to hold the handle 600 with one hand to fix the sewage tank 10, and gently rotate the closure 200 with the other hand to open or close the opening 130. This method eliminates the need for the user to precisely align or exert extra force to disassemble or install the closure 200, thus reducing the difficulty of cleaning the sewage tank 10.

[0187] Reference Figures 7-9 In some embodiments, the opening 130 connects the first chamber 111 and the second chamber 112, with the second chamber 112 located above the first chamber 111. A partition 900 is provided inside the receiving cavity 110, which can divide the first chamber 111 and the second chamber 112.

[0188] The wastewater tank 10 also includes a drive structure 400. The type of drive structure 400 has been described above and will not be repeated here. The following explanation will take a liquid pump as an example of drive structure 400.

[0189] The input end of the drive structure 400 is located at the bottom of the first chamber 111, and the output end of the drive structure 400 is located in the second chamber 112. The drive structure 400 can effectively extract and filter out liquid contaminants at the bottom. The drive structure 400 transports the liquid contaminants to the second chamber 112, while the solid-liquid separator 300 is located upstream of the output end of the drive structure 400 to ensure solid-liquid separation before the contaminants enter the second chamber 112.

[0190] With the above-described arrangement, the vertically distributed first chamber 111 and second chamber 112 make the internal structure of the wastewater tank 10 more compact, improving space utilization. Furthermore, the opening 130 makes cleaning the first chamber 111 and second chamber 112 easier. Users can easily access the waste in both chambers, simplifying maintenance and saving time and effort. In addition, this arrangement prevents liquid waste from accumulating at the bottom of the first chamber 111, reducing the risk of odor and bacterial growth.

[0191] Reference Figures 8-10 In some embodiments, the negative pressure port 150 is opened in the second chamber 112, and a sealing plate 500 is provided in the second chamber 112. The sealing plate 500 is provided corresponding to the negative pressure port 150 and covers the negative pressure port 150. The output end of the drive structure 400 is connected to the second chamber 112 outside the sealing plate 500.

[0192] Specifically, the sealing plate 500 includes a horizontally arranged first plate 510 and a vertically arranged second plate 520, which cooperate with the box 100 to cover and form a communicating cavity 114, and the communicating cavity 114 is connected to the negative pressure port 150.

[0193] It is understandable that the sealing plate 500 corresponds to and covers the negative pressure port 150 so that the negative pressure port 150 is connected to the first chamber 111 only through the connecting cavity 114. The airflow flows to the negative pressure source through this single channel, avoiding airflow leakage from the second chamber 112, ensuring stable airflow, maintaining the power of the negative pressure source, and ensuring cleaning efficiency.

[0194] Meanwhile, the first chamber 111 and the second chamber 112 are connected only through the drive structure 400. By using the solid-liquid separator 300 installed at the input end of the drive structure 400, solid waste can be prevented from entering the second chamber 112 through the drive structure 400, thereby achieving solid-liquid separation of the sewage tank 10.

[0195] Reference Figure 6 In some embodiments, the closure 200 is rotatably connected to the second sidewall 122 via a pivot, and a torsion spring is sleeved on the pivot.

[0196] With the above setup, when cleaning the sewage tank 10, the user only needs to hold the handle 600 with one hand to fix the sewage tank 10, and gently rotate the closure 200 with the other hand to open or close the opening 130. The torsion spring design allows the closure 200 to automatically return to its original position after being rotated under force, eliminating the need for additional operation, simplifying the usage process, reducing the difficulty of operation, and making it especially suitable for one-handed operation, thus improving the user experience.

[0197] Reference Figure 6 In some embodiments, the first sidewall 121 is the top of the sewage tank 10, and the handle 600 is disposed on the first sidewall 121. Thus, the handle 600 is configured to be disposed close to the closure 200 so that the user can open the closure 200 while holding the handle 600.

[0198] The design of the top of the wastewater tank 10, with a handle 600 positioned close to the closure 200, significantly enhances the user experience. While holding the handle 600, the user can easily operate the closure 200 to open or close the opening 130, simplifying the cleaning process and reducing operational steps. This ergonomic layout provides a more convenient way to use the tank. The handle 600 facilitates the user's lifting and carrying of the wastewater tank 10, especially when emptying wastewater or performing cleaning, allowing for easy movement. This design also enhances structural compactness, optimizes space utilization, gives the wastewater tank 10 a clean appearance, and increases the product's market appeal.

[0199] Reference Figure 6 In some embodiments, the angle α between the closure 200 and the horizontal direction X is not less than 60°.

[0200] With the above settings, the included angle α of not less than 60° ensures that the closure 200 maintains a stable angle when open. When the user holds the handle 600 with one hand, the other hand can easily rotate the closure 200 to open or close the opening 130, simplifying the operation process and improving ease of use.

[0201] In addition, an included angle of at least 60° facilitates the smooth discharge of dirt, avoids dirt residue or blockage caused by improper 200° angle of the closure, and improves cleaning efficiency.
