Embodiments for Carrying Out the Invention

[0026] Hereinafter, exemplary embodiments will be more comprehensively described with reference to the drawings. However, the exemplary embodiments can be implemented in various forms and should not be understood as being limited to the embodiments described herein. Rather, by providing these embodiments, the present disclosure can be made comprehensive and complete, and the concept of the exemplary embodiments can be fully conveyed to those skilled in the art. In the drawings, the same reference numerals indicate the same or similar mechanisms, so detailed descriptions thereof will be omitted. Also, the drawings are merely schematic diagrams of the present disclosure and are not necessarily drawn to scale.

[0027] In this specification, relative terms such as “up” and “down” are used to describe the relative relationship of one assembly to another, but these terms are used solely for convenience in this specification and are based, for example, on the illustrative orientation shown in the drawings. To be understood, if the marked device is inverted and its top and bottom reversed, the assembly described as “up” becomes the “down” assembly. When one mechanism is described as being “up” another mechanism, it may mean that the mechanism is integrally formed with the other mechanism, or that the mechanism is “directly” mounted on the other mechanism, or that the mechanism is “indirectly” mounted on the other mechanism via another mechanism.

[0028] The terms "one," "one," "the said," "the said," and "at least one" are used to indicate that there is one or more elements / components / etc. The terms "includes" and "have" openly indicate inclusion and that there may be other elements / components / etc. besides those listed, and terms such as "first," "second," and "third" are used merely as symbols and do not limit the number of objects.

[0029] In this application, unless otherwise specified or limited, the term “connection” should be interpreted in a broad sense, for example, “connection” may be a fixed connection, a detachable connection, or an integral structure, and may be a direct connection or an indirect connection via an intermediate medium. The term “and / or” simply describes the relationship between related objects and indicates that three types of relationships may exist, for example, A and / or B may refer to three situations: A existing alone, A and B existing simultaneously, or B existing alone. In this specification, the letter “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0030] An exemplary embodiment of the present disclosure provides a maintenance base station 10 for a cleaning apparatus 20, which, referring to Figures 1 to 5, may include a solid-liquid separation assembly 1 and a gas drying assembly 2, the solid-liquid separation assembly 1 being used to separate a mixture containing wastewater and solid waste to form wet waste and wastewater, the gas drying assembly 2 may include a fluid power source 21 and a heating mechanism 22, the fluid power source 21 being used to drive an airflow to form an airflow, and the heating mechanism 22 being used to heat the airflow to form a hot airflow, which dries the wet waste to form dry waste.

[0031] The maintenance base station 10 of the cleaning apparatus 20 of this disclosure separates solid waste from wastewater using a solid-liquid separation assembly 1, thereby preventing solid waste from clogging the drainage pipe when the maintenance base station 10 discharges wastewater. On the other hand, it forms a hot airflow using a fluid power source 21 and a heating mechanism 22, drying the wet waste with the hot airflow to form dry waste, thereby avoiding problems such as the wet waste deteriorating, bacteria multiplying, and generating foul odors.

[0032] In this exemplary embodiment, referring to Figures 1 to 3, the maintenance base station 10 may include a housing 101, in which the solid-liquid separation assembly 1 and the gas drying assembly 2 are installed. The specific structure of the housing 101 can be configured as needed.

[0033] Solid-liquid separation assembly 1 is used to separate a mixture containing wastewater and solid waste to form wet waste and wastewater. Solid-liquid separation assembly 1 may also be a gravity-type filtration separation assembly.

[0034] Specifically, referring to Figures 1 and 2, the gravity-type filtration separation assembly may include a wet waste storage chamber 11, which can be installed in a cylindrical structure, and the central axis of rotation of the wet waste storage chamber 11 is parallel to the horizontal plane, i.e., the cylindrical wet waste storage chamber 11 is positioned horizontally. A filter mesh 12 is installed at the bottom of the wet waste storage chamber 11, and the filter mesh 12 is installed in an arc-shaped plate that fits the wet waste storage chamber 11, i.e., the filter mesh 12 becomes part of the cylindrical structure. After a mixture containing wastewater and solid waste is flowed into the wet waste storage chamber 11, gravity causes the wastewater to flow out through the filter mesh 12, leaving only solid waste in the wet waste storage chamber 11, and the solid waste becomes wet waste as it is immersed in the wastewater for a long time.

[0035] The solid-liquid separation assembly 1 separates solid waste from wastewater, preventing solid waste from clogging the drainage pipes when the maintenance base station 10 discharges wastewater.

[0036] Furthermore, by installing the wet waste storage chamber 11 in a cylindrical structure and arranging it horizontally, the wet waste storage chamber 11 has a bottom, and the filter mesh 12 can be installed at the bottom of the wet waste storage chamber 11. This allows for sufficient drainage of wastewater from the wet waste storage chamber 11, reduces or even avoids the accumulation of wastewater within the wet waste storage chamber 11. Additionally, the inner wall of the wet waste storage chamber 11 is relatively smooth, without corners or bends, thus preventing wastewater from accumulating at corners or bends. Moreover, the wet waste storage chamber 11 has a waste outlet 111, which may be located on the left or right side of the central axis of the wet waste storage chamber 11.

[0037] In some other exemplary embodiments of the present disclosure, the solid-liquid separation assembly 1 may be a centrifugal filtration separation assembly. The centrifugal filtration separation assembly may include a wet waste storage chamber 11 and a wastewater collection chamber, the wet waste storage chamber 11 of which can be installed in a cylindrical structure, the cylindrical wet waste storage chamber 11 of which can be positioned horizontally so that the axis of rotation of the wet waste storage chamber 11 is parallel to the horizontal plane, or the cylindrical wet waste storage chamber 11 of which can be positioned vertically so that the axis of rotation of the wet waste storage chamber 11 is perpendicular to the horizontal plane. The wall of the wet waste storage chamber 11 is provided with a plurality of through holes, which are arranged substantially uniformly. The wastewater collection chamber is enclosed outside the wet waste storage chamber 11 and a gap is provided between it and the wet waste storage chamber 11.

[0038] The centrifugal filtration separation assembly may further include a drive motor, the rotation shaft of which is fixedly connected to the wet waste storage chamber 11 and installed coaxially with the central rotation axis of the wet waste storage chamber 11, and the drive motor can drive the wet waste storage chamber 11 to rotate at high speed, and the centrifugal force generated in the process of high-speed rotation causes the wastewater to be ejected from multiple through holes in the wall of the wet waste storage chamber 11, thus separating the mixture containing wastewater and solid waste to form wet waste and wastewater. Furthermore, the ejected wastewater is shielded and collected in a wastewater collection chamber, preventing the wastewater from splashing onto other components inside the maintenance base station 10.

[0039] In this exemplary embodiment, referring to Figures 1 to 3, the gas drying assembly 2 may include a fluid power source 21 and a heating mechanism 22. The fluid power source 21 may include a fan. The fluid power source 21 has a first air outlet 211 and is used to drive the airflow to form an airflow. The structure of the fluid power source 21 will not be described in detail here.

[0040] The heating mechanism 22 may include a heating element. The heating mechanism 22 may also be a PTC heater, which employs a combination of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency, and is an automatic constant temperature, energy-saving electric heater. Its outstanding feature is its safety performance; in any application, it does not exhibit the "reddening" phenomenon on the surface like electric tube heaters, thus eliminating safety risks such as burns and fires.

[0041] The heating mechanism 22 has a second air inlet 221 and a second air outlet 222, the second air inlet 221 being connected to the first air outlet 211, and the heating mechanism 22 is used to heat the airflow and form a hot airflow. Specifically, a fan rotates to drive the airflow and form an airflow, which enters the heating mechanism 22 through the first air outlet 211 and the second air inlet 221, where the heating mechanism 22 heats the airflow to form a hot airflow, which dries the wet waste to form dry waste. Dry waste is less likely to deteriorate, and is less likely to breed bacteria or produce foul odors, thus avoiding problems such as deterioration of wet waste, bacterial growth, and the generation of foul odors.

[0042] Furthermore, the maintenance base station 10 may further include a dry waste collection chamber 3 and a waste transfer mechanism 4. The dry waste collection chamber 3 is used to store dry waste and has a waste inlet, which is connected to a waste outlet 111 of the wet waste storage chamber 11. The waste transfer mechanism 4 is used to transfer wet waste from the wet waste storage chamber 11 to the dry waste collection chamber 3.

[0043] In this exemplary embodiment, referring to Figures 1 to 3, the gas drying assembly 2 may be directly connected to the dry waste collection chamber 3, where the wet waste is directly dried.

[0044] Specifically, the dry waste collection chamber 3 has a third air inlet 31 and a third air outlet 32. In other words, the dry waste collection chamber 3 is equipped with a third air inlet 31 and a third air outlet 32, and the third air inlet 31 is connected to the second air outlet 222. A hot airflow formed by passing through the fluid power source 21 and the heating mechanism 22 is allowed to flow into the dry waste collection chamber 3, and the hot airflow can dry the wet waste stored in the dry waste collection chamber 3 to form dry waste.

[0045] In this case, it is necessary to first transfer the wet waste from the solid-liquid separation assembly 1 to the dry waste collection chamber 3 via the wet waste transfer mechanism 4.

[0046] The dry waste collection chamber 3 is installed in a removable manner, meaning it can be removed from the maintenance base station 10. The dry waste collection chamber 3 is replaceable; for example, it may be disposable. After a certain amount of dry waste is collected, the dry waste collection chamber 3 can be disposed of directly along with the dry waste inside. Alternatively, a garbage bag may be placed inside the dry waste collection chamber 3, and after a certain amount of dry waste is collected, the garbage bag can be disposed of along with the dry waste inside. Therefore, by drying wet waste inside the dry waste collection chamber 3, waste residue can be avoided as much as possible.

[0047] Furthermore, when wet waste dries and becomes dry waste, it tends to adhere to the side walls of the waste storage chamber, and since dry waste is more difficult to clean than wet waste, when it dries in the wet waste storage chamber 11 of the solid-liquid separation assembly 1, the dry waste formed in the wet waste storage chamber 11 tends to adhere to the side walls of the wet waste storage chamber 11, making it impossible to clean. After accumulating for a long time, the waste in the wet waste storage chamber 11 deteriorates and becomes smelly, and the waste also clogs the filter mesh or through holes on the wet waste storage chamber 11, preventing the wet waste storage chamber 11 from filtering or discharging wastewater, which causes the solid-liquid separation assembly 1 to malfunction. On the other hand, when drying in the dry waste collection chamber 3, the above technical problems do not occur, and furthermore, since the dry waste collection chamber 3 is replaceable, the residue of dry waste can be avoided as much as possible.

[0048] Referring to Figure 2, if the solid-liquid separation assembly 1 is a gravity-type filtration separation assembly, the dry waste collection chamber 3 may be located to the left or right of the central axis of the wet waste storage chamber 11, that is, the dry waste collection chamber 3 is located below the waste outlet 111 of the wet waste storage chamber 11. Specifically, the waste transfer mechanism 4 may include a motor 41, a rotating shaft 42, and a scraper 43, with the motor 41 located outside the wet waste storage chamber 11, and the rotating shaft 42 and scraper 43 located inside the wet waste storage chamber 11. The drive shaft of the motor 41 is fixedly connected to the rotating shaft 42, and the motor 41 can drive the rotating shaft 42 to rotate. The scraper 43 is connected to the rotating shaft 42, and as the motor 41 drives the rotating shaft 42 to rotate, the rotating shaft 42 also drives the scraper 43 to rotate, and the scraper 43 transfers dry waste from the wet waste storage chamber 11 to the dry waste collection chamber 3.

[0049] If the solid-liquid separation assembly 1 is a centrifugal filtration separation assembly, the dry waste collection chamber 3 may be located at the bottom of the wet waste storage chamber 11, and the waste transfer mechanism 4 may be located at the bottom of the wet waste storage chamber 11, specifically, an opening is provided at the bottom of the wet waste storage chamber 11. The waste transfer mechanism 4 may include a motor and a baffle, the baffle being rotatably installed at the opening of the wet waste storage chamber 11, the motor being connected to the baffle and driving the baffle to rotate and displace the baffle from the opening, thereby causing the dry waste in the wet waste storage chamber 11 to fall into the dry waste collection chamber 3 by gravity.

[0050] In some other exemplary embodiments of this disclosure, the gas drying assembly 2 may be directly connected to the solid-liquid separation assembly 1, thereby directly drying the wet waste in the solid-liquid separation assembly 1. By installing it in this manner, the hot airflow can dry the waste and the solid-liquid separation assembly 1 at the same time, avoiding problems such as the deterioration of the remaining wet waste in the solid-liquid separation assembly 1, bacterial growth, and the generation of foul odors.

[0051] In this case, the wet waste storage chamber 11 has a third air inlet and a third air outlet, that is, a third air inlet and a third air outlet are installed in the wet waste storage chamber 11, the third air inlet is connected to the second air outlet 222, and a hot airflow formed through the fluid power source 21 and the heating mechanism 22 is allowed to flow into the wet waste storage chamber 11, and the wet waste stored in the wet waste storage chamber 11 can be dried by the hot airflow to form dry waste.

[0052] The maintenance base station 10 may further include a dry waste collection chamber 3 and a waste transfer mechanism 4. The dry waste collection chamber 3 is used to store dry waste and has a waste inlet, which is connected to the waste outlet 111 of the wet waste storage chamber. The waste transfer mechanism 4 is used to transfer dry waste from the wet waste storage chamber 11 to the dry waste collection chamber 3. The specific structure of the waste transfer mechanism 4 may be the same as the specific structure of the waste transfer mechanism 4 in the exemplary embodiment described above, so its description is omitted here.

[0053] In this exemplary embodiment, since the dry waste collection chamber 3 is not installed in a sealed manner, the hot airflow after drying the wet waste flows into the housing 101, allowing other components inside the housing 101 to be dried.

[0054] Furthermore, as shown in Figure 2, a wastewater suction fan 102 may be installed inside the housing 101, and the wastewater suction fan 102 can be used to discharge hot air from inside the housing 101.

[0055] After the hot airflow dries the wet waste, the temperature of the hot airflow decreases, but the moisture in the wet waste forms water vapor and mixes with the hot airflow. This water vapor has a certain corrosive effect on each assembly and mechanism in the maintenance base station 10. If water vapor remains in the maintenance base station 10 for a long time, it will affect the safety performance and service life of the maintenance base station 10. Furthermore, the water vapor will re-moisten the dry waste, and the re-moistened dry waste will deteriorate, allowing bacteria to proliferate and causing problems such as foul odors.

[0056] To solve the above technical problems, in some further embodiments of the present disclosure, referring to Figure 4, in which the cooling pipe 53 is shown as a dashed line because it is shielded, the maintenance base station 10 may further include a dehumidification mechanism 5, the dehumidification mechanism 5 having a fourth air inlet 51 and a fourth air outlet 52, that is, the dehumidification mechanism 5 is equipped with a fourth air inlet 51 and a fourth air outlet 52, the fourth air inlet 51 is connected to a third air outlet 32 ​​so that a hot airflow that has dried the wet dust flows into the dehumidification mechanism 5 through the third air outlet 32 ​​and the fourth air inlet 51, and the dehumidification mechanism 5 is used to dehumidify the hot airflow that has dried the wet dust.

[0057] The dehumidification mechanism 5 dehumidifies the hot airflow after the wet waste has been dried, thereby reducing the water vapor content in the hot airflow, preventing the corrosive effects of water vapor on each assembly and mechanism in the maintenance base station 10, ensuring the safety performance and service life of the maintenance base station 10, and further preventing moisture from returning to the dried waste, thereby preventing problems such as deterioration of the dried waste, bacterial growth, and the generation of unpleasant odors.

[0058] In this exemplary embodiment, the dehumidification mechanism 5 may be a condensation-type dehumidification mechanism 5. Specifically, the dehumidification mechanism 5 may include a housing and cooling pipes 53, the cooling pipes 53 being provided inside the housing and an airflow passage being provided between the cooling pipes 53. The cooling pipes 53 have a coolant inlet 531 and a coolant outlet 532. A fourth air inlet 51 is provided at the bottom of the housing to allow a relatively humid hot airflow to flow into the housing through the bottom of the housing, the hot airflow coming into contact with the cooling pipes 53, the water vapor in the hot airflow being cooled and condensed into water, thereby reducing the humidity of the hot airflow and achieving the objective of dehumidifying the hot airflow after drying the wet dust.

[0059] Furthermore, a condensate outlet 54 is installed in the housing, and the condensate outlet 54 is located at the bottom of the housing. Due to gravity, the condensate flows downward, and by placing the condensate outlet 54 at the bottom of the housing, the condensate is almost completely discharged, preventing it from remaining inside the dehumidification mechanism 5.

[0060] The fourth air outlet 52 is provided at the top of the housing, allowing the dried airflow to flow out through the fourth air outlet 52 located at the top of the housing, thereby preventing the generated condensed water from causing moisture to return to the dried airflow and ensuring the dryness of the dried airflow.

[0061] Although the temperature of the airflow after dehumidification by the dehumidification mechanism 5 decreases, the temperature is still relatively high. Directly discharging the relatively high-temperature airflow would waste resources and affect the operating environment of the maintenance base station 10. By connecting the fourth air outlet 52 to the first air inlet 212 of the fluid power source 21, the airflow after dehumidification by the dehumidification mechanism 5 flows directly into the fluid power source 21. The acceleration by the fluid power source 21 creates an airflow with a relatively high flow velocity, which dries the subsequent wet waste. In other words, the fluid power source 21, heating mechanism 22, wet waste storage chamber 11 (or dry waste collection chamber 3), and dehumidification mechanism 5 form a closed-loop airflow circulation system. Furthermore, the amount of heating to the airflow by the heating mechanism 22 can be reduced, achieving the objectives of energy saving and emission reduction while simultaneously not affecting the operating environment of the maintenance base station 10. The fourth air outlet 52 of the dehumidification mechanism 5 may be directly or indirectly connected to the first air inlet 212 of the fluid power source 21.

[0062] The cooling pipe 53 has a coolant inlet 531 and a coolant outlet 532. Coolant can be replenished to the cooling pipe 53 via the coolant inlet 531, and if the maintenance base station 10 is not used for a long period of time, the coolant can be discharged via the coolant outlet 532 to prevent coolant leakage.

[0063] Of course, in some other exemplary embodiments of this disclosure, the dehumidification mechanism 5 may be an adsorption type dehumidification mechanism 5. Specifically, the dehumidification mechanism 5 may include a housing and a desiccant, the desiccant being provided inside the housing. The housing is provided with a fourth air inlet 51 and a fourth air outlet 52, the humid hot airflow entering the housing through the fourth air inlet 51, the desiccant adsorbing water vapor in the humid hot airflow and releasing the dry gas through the fourth air outlet 52. The desiccant may be a conventionally used desiccant, which will not be described here.

[0064] Furthermore, in some other exemplary embodiments of this disclosure, if a hot airflow dries the wet waste in the wet waste storage chamber 11 to form dry waste, the fourth air inlet 51 of the dehumidification mechanism 5 may be connected to the wet waste storage chamber 11.

[0065] Furthermore, the fluid power source 21 and the heating mechanism 22 are sealed together. The heating mechanism 22 and the dry waste collection chamber 3 are sealed together, and the dry waste collection chamber 3 and the dehumidification mechanism 5 are sealed together, or the heating mechanism 22 and the wet waste storage chamber 11 are sealed together, and the wet waste storage chamber 11 and the dehumidification mechanism 5 are sealed together. The dehumidification mechanism 5 and the fluid power source 21 are sealed together.

[0066] Specifically, the second air inlet 221 and the first air outlet 211 are sealed together, the third air inlet 31 and the second air outlet 222 are sealed together, the fourth air inlet 51 and the third air outlet 32 ​​are sealed together, and the fourth air outlet 52 and the first air inlet 212 are sealed together. In other words, the fluid power source 21, the heating mechanism 22, the wet waste storage chamber 11 (or dry waste collection chamber 3), and the dehumidification mechanism 5 form a closed-loop and sealed airflow circulation system. The waste still has a certain odor, and this setup avoids the dissipation of airflow, thereby preventing the airflow from carrying the odor of the waste to the outside, and thus preventing the odor from spreading throughout the maintenance base station 10. Furthermore, by confining the entire hot air within this circulation system, drying efficiency can be improved.

[0067] In this exemplary embodiment, referring to Figure 2, the maintenance base station 10 may further include a wastewater inlet pipe 103 and a mixed waste passage 104, the mixed waste passage 104 of which may be located above the solid-liquid separation assembly 1, one end of the wastewater inlet pipe 103 being connected to the cleaning device and the other end of the wastewater inlet pipe 103 extending into the mixed waste passage 104, through which a mixture containing wastewater and solid waste from the cleaning device can be introduced into the mixed waste passage 104 and flowed through the mixed waste passage 104 into the solid-liquid separation assembly 1.

[0068] In some exemplary embodiments of the present disclosure, referring to Figure 5, the maintenance base station 10 may further include a mixed waste storage chamber 6 used for storing wastewater or a mixture containing wastewater and solid waste. The mixed waste storage chamber 6 can be formed by installing an openable / closable baffle at the bottom of the mixed waste passage 104. When the amount of mixture containing wastewater and solid waste generated by the cleaning device 20 is small, the mixture is stored in the mixed waste storage chamber 6, and the system awaits the introduction of the next amount of mixture containing wastewater and solid waste generated by the cleaning device 20, and only when the mixture reaches a set amount is solid-liquid separation, wastewater discharge, and wet waste drying performed.

[0069] In a direction perpendicular to the horizontal plane, the height of the mixed waste storage chamber 6 is greater than the height of the solid-liquid separation assembly 1. For example, the mixed waste storage chamber 6 may be installed directly above the solid-liquid separation assembly 1. A drain port 62 is installed at the bottom of the mixed waste storage chamber 6. When solid-liquid separation is required, the drain port 62 can be opened directly, allowing the mixture to flow directly into the wet waste storage chamber 11 of the solid-liquid separation assembly 1 due to gravity.

[0070] Of course, the mixed waste storage chamber 6 may be installed diagonally above the solid-liquid separation assembly 1, and a drain port 62 is installed at the bottom of the mixed waste storage chamber 6, which can be connected to the wet waste storage chamber 11 of the solid-liquid separation assembly 1 through piping. When solid-liquid separation is required, the drain port 62 can be opened directly, allowing the mixture to flow into the wet waste storage chamber 11 of the solid-liquid separation assembly 1 through the piping due to gravity.

[0071] Furthermore, the bottom wall 61 of the mixed waste storage chamber 6 may be installed in a conical shape, so that the bottom wall 61 has a lowest point. For example, the bottom wall 61 of the mixed waste storage chamber 6 may be installed in an inverted cone or inverted pyramidal shape, with the apex of the inverted cone or inverted pyramidal shape being the lowest point, and a drain port 62 may be installed in the bottom wall 61, with the drain port 62 located at the lowest point of the bottom wall 61. For example, the drain port 62 may be located at the apex of the inverted cone or inverted pyramidal shape.

[0072] By installing it in this manner, almost all of the mixture in the mixed waste storage chamber 6 can flow into the solid-liquid separation assembly 1, preventing the mixture from remaining in the mixed waste storage chamber 6 and avoiding problems such as the deterioration of solid waste remaining in the mixed waste storage chamber 6, the proliferation of bacteria, and the generation of foul odors.

[0073] Of course, in some other exemplary embodiments of the present disclosure, the bottom wall 61 of the mixed waste storage chamber 6 may be installed at an incline, or the bottom wall 61 may have a lowest point, to facilitate the discharge of the mixture from the mixed waste storage chamber 6.

[0074] In this exemplary embodiment, referring to Figure 2, the maintenance base station 10 may further include a spray head 7, which is located within the mixed waste passage 104 and is used to clean the mixed waste passage 104.

[0075] Of course, in some exemplary embodiments of this disclosure, referring to Figure 5, if a mixed waste storage chamber 6 is installed, the spray head 7 may be installed inside the mixed waste storage chamber 6 and the spray head 7 is used to clean the mixed waste storage chamber 6. Specifically, the spray head 7 may include a total spray pipe, which has a first end and a second end installed relative to each other, the first end of the total spray pipe being used to connect to a clean water pipe, and a number of sub-spray pipes being connected to the second end of the total spray pipe, which spray water through the spray pipes to perform cleaning.

[0076] Furthermore, the spray head 7 may include a spray pipe, which has a first end and a second end that are positioned relative to each other. The first end of the spray pipe is used to connect to a clean water pipe, and the second end of the spray pipe is set up as a closed end to prevent clean water from flowing directly out from the second end and failing to clean the mixed waste storage chamber 6. Multiple through holes are provided in the wall of the spray pipe, which are uniformly arranged from top to bottom and along the circumferential wall of the spray pipe. Clean water flowing in from the first end is sprayed through the multiple through holes onto the inner wall of the mixed waste storage chamber 6, thereby cleaning the mixed waste storage chamber 6. The length of the spray pipe is approximately the same as the depth of the mixed waste storage chamber 6.

[0077] Of course, in some other exemplary embodiments of this disclosure, the length of the spray tube can be shortened, and a drive mechanism can be installed to drive the spray tube up and down so that the spray tube can spray clean each part of the mixed waste storage chamber 6. Furthermore, the structure of the spray head 7 may be other structures, which will not be described here.

[0078] In this exemplary embodiment, referring to Figure 1, the maintenance base station 10 may further include a wastewater discharge mechanism 8, which is used to discharge the wastewater separated by the solid-liquid separation assembly 1. The wastewater discharge mechanism 8 may include a wastewater pipe, one end of which is directly connected to the wastewater outlet of the solid-liquid separation assembly 1, and the other end of which is directly connected to a sewer pipe, so that the wastewater separated by the solid-liquid separation assembly 1 flows directly into the wastewater pipe and is discharged directly into the sewer pipe by the wastewater pipe.

[0079] Of course, in some other exemplary embodiments of this disclosure, the wastewater discharge mechanism 8 may further include a wastewater collection bucket, which is installed below the solid-liquid separation assembly 1, allowing wastewater separated by the solid-liquid separation assembly 1 to flow directly into the wastewater collection bucket, with one end of the wastewater pipe directly connected to the wastewater outlet of the wastewater collection bucket. If it is inconvenient to connect the maintenance base station 10 directly to the sewer pipe, the wastewater can be collected in the wastewater collection bucket, and then the maintenance base station 10 can be moved to the sewer pipe and discharged directly into the sewer pipe. Alternatively, if there is little wastewater, the wastewater can be collected in the wastewater collection bucket, and if there is a large amount of wastewater, it can be discharged directly into the sewer pipe.

[0080] The wastewater discharge mechanism 8 may further include a water pump, which is connected between the wastewater pipe and the wastewater collection bucket, and which extracts wastewater into the wastewater pipe and then discharges it directly into the sewer pipe through the wastewater pipe.

[0081] In this exemplary embodiment, referring to Figures 1 and 2, the maintenance base station 10 may further include a clean water tank 105, a clean water pump 106, a tap water connector 107, and a float 108. The clean water tank 105 is used to store clean water. One end of the tap water connector 107 is used to connect to a faucet, and the other end of the tap water connector 107 communicates with the inside of the clean water tank 105. The tap water connector 107 is used to supply tap water to the clean water tank 105. The float 108 is located inside the clean water tank 105 and is used to detect the water level inside the clean water tank 105. The clean water pump 106 is used to draw clean water from the clean water tank 105 to the cleaning device 20.

[0082] Based on the same inventive concept, exemplary embodiments of the present disclosure provide a cleaning system, which, referring to Figure 6, may include a cleaning device 20 and a maintenance base station 10 of the cleaning device 20, where the maintenance base station 10 of the cleaning device 20 is the maintenance base station 10 of the cleaning device 20 described in any one of the above paragraphs. The specific structure of the maintenance base station 10 has already been described in detail above and will not be described here.

[0083] The cleaning device 20 is used to clean a surface to be cleaned (for example, a floor), and after the cleaning device 20 cleans the surface, it forms a mixture containing wastewater and solid debris. The cleaning device 20 may also be a floor cleaning machine. Because the mixture is stored inside the cleaning device 20, the inside of the cleaning device 20 is relatively humid, and as time passes, the remaining debris deteriorates, bacteria proliferate, and problems such as the generation of foul odors are likely to occur.

[0084] Referring to Figure 3, the ventilation passage 9 is indicated by a bold black arrow. The ventilation passage 9 is installed inside the maintenance base station 10, and one end of the ventilation passage 9 can communicate with the third air outlet 32. That is, one end of the ventilation passage 9 is connected to the dry waste collection chamber 3. As a result, the hot airflow that has dried the wet waste flows into the ventilation passage 9 and then flows through the ventilation passage 9 to the cleaning device 20, thereby drying the cleaning device 20. With this setup, the hot airflow after drying the wet waste can be further used to dry the cleaning device 20, improving the efficiency of hot airflow utilization and contributing to energy saving and emission reduction. Of course, if the wet waste is dried within the solid-liquid separation assembly 1, one end of the ventilation passage 9 may be connected to the solid-liquid separation assembly 1.

[0085] In addition, in some other exemplary embodiments of this disclosure, one end of the air passage 9 communicates with a second air outlet 222, that is, one end of the air passage 9 is connected to the air outlet of the heating mechanism 22, and the other opposite end of the air passage 9 communicates with the cleaning device 20, so that the hot airflow formed by heating by the heating mechanism 22 flows into the air passage 9 and then flows through the air passage 9 to the cleaning device 20, and thus the hot airflow can dry the cleaning device 20. By installing it in this manner, the hot airflow formed by heating by the heating mechanism 22 can directly dry the cleaning device 20, which is advantageous in improving the drying efficiency of the cleaning device 20.

[0086] The terms "parallel" and "perpendicular" as used in this application do not necessarily mean perfectly parallel or perpendicular, but may have a certain degree of error. For example, if the angle between the two is 0° or more and 5° or less, they are considered parallel to each other, and if the angle between the two is 85° or more and 95° or less, they are considered perpendicular to each other.

[0087] A person skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and putting the disclosures herein into practice. This application is intended to cover any variations, uses, or adaptive changes of the present disclosure, which will follow the general principles of the present disclosure and include common or customary technical means known in the art that are not disclosed herein. The specification and examples are to be considered merely illustrative, and the true scope and spirit of the present disclosure are indicated by the appended claims. [Explanation of symbols]
