Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a self-cleaning sewage discharge device and cleaning equipment. Background Technology

[0002] In the practical application of cleaning equipment, the automated management of wastewater tanks has always been a key bottleneck restricting the improvement of equipment performance. Traditional cleaning equipment wastewater tank systems generally rely on manual intervention to complete core operations: during the sewage discharge phase, the sealing structure of the wastewater tank needs to be manually opened, and after the sewage discharge is completed, it needs to be manually closed. The whole process is not only labor-intensive, but may also cause sewage overflow due to misjudgment of the timing of operation, polluting the working environment. Similarly, the cleaning of the wastewater tank also relies on manual disassembly and rinsing, which is not only labor-intensive, but also prone to residual stains, mold, and bacterial growth due to inadequate cleaning. This not only affects the service life of the equipment, but may also cause secondary pollution in subsequent cleaning operations, affecting environmental hygiene and user health. Utility Model Content

[0003] The main purpose of this utility model is to provide a self-cleaning sewage discharge device and cleaning equipment, which aims to solve the technical problems of existing cleaning equipment sewage tanks relying on manual intervention to complete sewage discharge and cleaning operations, resulting in high labor costs, easy environmental pollution, and low hygiene performance and service life of the equipment.

[0004] In order to achieve the above-mentioned utility model objectives, this utility model proposes a self-cleaning sewage discharge device, including a housing, a fluid receiving component, a cleaning and stirring mechanism, and a sealing sewage discharge mechanism;

[0005] The fluid containment assembly includes a first containment box disposed on the housing, the first containment box having a drain hole communicating with the housing, and the sealing drain mechanism disposed on the first containment box and arranged opposite to the drain hole;

[0006] The cleaning and stirring mechanism includes a stirring component, which is disposed on the first receiving tank and is movably connected to the sealing and draining mechanism. The stirring component is used to stir the first fluid in the first receiving tank and to control the opening and closing state of the sealing and draining mechanism and the drain hole through the linkage between the stirring component and the sealing and draining mechanism.

[0007] Furthermore, the stirring assembly includes a drive motor, stirring blades, and transmission components;

[0008] The first container is provided with a first receiving groove, the drive motor is provided in the first receiving groove, the stirring fan blade is located in the first container and is connected to the first output shaft of the drive motor that extends into the first container, the end of the drive motor away from the first output shaft is also provided with a second output shaft, the transmission component is located outside the first container and connected to the second output shaft, and the transmission component is in contact with the sealing and sewage discharge mechanism.

[0009] Furthermore, the transmission component includes a one-way bearing and a transmission module. The one-way bearing is sleeved on the second output shaft, and the transmission module is sleeved on the side of the one-way bearing away from the second output shaft and is movably connected to the sealing and sewage discharge mechanism. When the drive motor rotates in the first direction, the second output shaft drives the one-way bearing to rotate freely relative to the transmission module. When the drive motor rotates in the second direction, the second output shaft drives the one-way bearing to be locked, so that the one-way bearing drives the transmission module to rotate synchronously.

[0010] Furthermore, the transmission module includes a transmission body and a transmission inclined part integrally connected to the transmission body. The transmission body is sleeved on the one-way bearing. The transmission inclined part is disposed on the side of the transmission body away from the one-way bearing and is slidably connected to the sealing and sewage discharge mechanism. The transmission inclined part extends spirally upward in a direction away from the drive motor.

[0011] Further, the sealing and draining mechanism includes a sealing telescopic assembly and a linkage rod. The sealing telescopic assembly is disposed on the first receiving box and extends into the first receiving box, opposite to the drain hole. The linkage rod is located outside the first receiving box and connected to the sealing telescopic assembly. The end of the linkage rod away from the sealing telescopic assembly is slidably connected to the transmission inclined surface. When the drive motor rotates in the first direction, the one-way bearing rotates freely relative to the transmission module. Under the action of the sealing telescopic assembly, the linkage rod remains in contact with the bottom of the transmission inclined surface. The sealing telescopic assembly is in a retracted state and seals the drain hole. When... When the drive motor rotates in the second direction, the one-way bearing drives the transmission module to rotate synchronously. The transmission inclined section rotates with the transmission body and pushes the linkage rod to rise along the spiral path of the transmission inclined section. The linkage rod drives the sealing telescopic assembly to extend to open the drain hole. When the linkage rod rises to the preset highest point, the drive motor stops rotating or rotates in the first direction. Under the action of the contraction force of the sealing telescopic assembly, the linkage rod generates downward pressure along the transmission inclined section, driving the transmission body to generate rotational torque. This torque causes the one-way bearing to rotate freely. As the transmission body rotates, the linkage rod descends, and the sealing telescopic assembly contracts to the preset position to seal the drain hole.

[0012] Furthermore, the sealing and draining mechanism also includes a position detection component, which is disposed on the top of the first receiving box and located on the upward path of the linkage rod. The position detection component is used to detect the position of the linkage rod and to control the opening and closing state of the sealing telescopic assembly and the drain hole through the forward and reverse rotation mechanism of the drive motor.

[0013] Furthermore, the sealing telescopic assembly includes a sealing shaft, a telescopic component, and a sealing sleeve. The first receiving box is provided with a second receiving groove. The sealing shaft is disposed in the second receiving groove and connected to the linkage rod. The end of the sealing shaft away from the linkage rod passes through the second receiving groove. The sealing sleeve is located in the first receiving box and is detachably connected to the end of the sealing shaft away from the second receiving groove. The telescopic component is disposed on the sealing shaft and is located between the second receiving groove and the sealing sleeve.

[0014] Furthermore, the telescopic component includes a fixed sleeve and a telescopic body. The fixed sleeve is located inside the first receiving box and is sleeved on the end of the second receiving groove away from the linkage rod. The sealing shaft passes through the fixed sleeve, and a baffle is provided at the end of the sealing shaft near the sealing sleeve. The telescopic body is sleeved on the sealing shaft and connected between the fixed sleeve and the baffle.

[0016] The liquid level detection component is installed on the first container and is used to detect the liquid level of the first fluid in the first container. The second container is installed on the housing and connected to the outside of the first container. The water pump is installed on the housing and connected to the second container. The air pump is installed on the housing and connected to the first container. The water pump delivers the second fluid in the second container to the first container through the air pump.

[0017] This utility model also discloses a cleaning device, including the self-cleaning sewage discharge device described in any of the above embodiments.

[0018] Beneficial effects:

[0019] This utility model discloses a self-cleaning sewage discharge device, comprising a housing, a fluid containing assembly, a cleaning and stirring mechanism, and a sealing sewage discharge mechanism. The fluid containing assembly includes a first containing tank mounted on the housing, with a sewage discharge hole penetrating the housing. The sealing sewage discharge mechanism is mounted on the first containing tank and arranged opposite to the sewage discharge hole. The cleaning and stirring mechanism includes a stirring component mounted on the first containing tank and movably connected to the sealing sewage discharge mechanism.

[0041] Reference Figures 1-5 This embodiment provides a self-cleaning sewage discharge device, including a housing 1, a fluid receiving component 2, a cleaning and stirring mechanism 3, and a sealing sewage discharge mechanism 4;

[0042] The fluid containment assembly 2 includes a first containment box 20 disposed on the housing 1. The first containment box 20 is provided with a drain hole 22 that communicates with the housing 1. The sealing drain mechanism 4 is disposed on the first containment box 20 and is arranged opposite to the drain hole 22.

[0043] The cleaning and stirring mechanism 3 includes a stirring component, which is disposed on the first receiving tank 20 and is movably connected to the sealing and draining mechanism 4. The stirring component is used to stir the first fluid in the first receiving tank 20 and to control the opening and closing state of the sealing and draining mechanism 4 and the drain hole 22 through the linkage movement between the stirring component and the sealing and draining mechanism 4.

[0044] In the above embodiments, the self-cleaning sewage discharge device includes core components such as a housing 1, a fluid containing assembly 2, and a cleaning and stirring mechanism 3. The housing 1 forms the external structural frame of the entire device. The fluid containing assembly 2 mainly consists of a first containing tank 20 mounted on the housing 1. This first containing tank 20 is preferably a sewage tank, used to collect and temporarily store sewage generated during use. A sewage discharge hole 22, penetrating the housing 1, is located at the bottom of the first containing tank 20, ensuring complete sewage discharge. Simultaneously, a through hole is also provided at a corresponding position on the housing 1, so that the two holes are on the same axis and interconnected, forming a complete sewage discharge channel. The sealing sewage discharge mechanism 4 is installed on the top of the first containing tank 20 and extends inwards. The bottom drain hole 22 is arranged vertically opposite to the bottom; the cleaning and stirring mechanism 3 includes a stirring component installed on the first receiving tank 20. The stirring component extends into the tank from the top of the sewage tank. The stirring component is used to stir the sewage in the tank to prevent impurities in the sewage from settling to the bottom; there is a movable connection between the stirring component and the sealing and draining mechanism 4. This connection allows the stirring component to drive the sealing and draining mechanism 4 to move up and down through the forward and reverse rotation of the stirring component motor. The forward and reverse rotation of the motor component in the stirring component can drive the linkage movement of the sealing and draining mechanism 4, thereby controlling the closing or opening of the sealing and draining mechanism 4 and the drain hole 22.

[0045] The stirring component not only has a stirring function, but also controls the sewage discharge switch. When the drive motor 301 of the stirring component rotates forward, it drives the sealing sewage discharge mechanism 4 to rise through the transmission structure. The sealing sewage discharge mechanism 4 separates from the sewage discharge hole 22, opening the sewage discharge port to start discharging sewage. At this time, the stirring component continues to rotate, stirring the sewage and accelerating the sewage flow. At the same time, the flowing fluid can "hit" the inner wall of the tank, achieving dynamic cleaning of the tank body, reducing dirt adhesion, completing automatic cleaning inside the tank, and assisting in emptying the sewage tank while completing the internal rinsing and cleaning of the tank body. When the drive motor 301 reverses, the sealing sewage discharge mechanism 4 descends again and fits tightly against the sewage discharge hole 22. The lower end of the sealing sewage discharge mechanism 4 tightly abuts against the sewage discharge hole 22 to achieve the sealing function, closing the sewage discharge port and preventing sewage leakage. Therefore, the automatic closing / opening process of the sealing sewage discharge mechanism 4 and the sewage discharge hole 22 is completed by the mechanical linkage of the stirring component (forward and reverse rotation mechanism), realizing the automatic opening and closing of the sewage discharge hole 22 without the need for manual operation of sewage discharge. At the same time, the stirring component continuously agitates the sewage, effectively reducing dirt deposition, reducing the frequency of manual cleaning, reducing the risk of residual sewage leakage, and indirectly reducing the probability of environmental pollution, thereby improving the hygiene performance and service life of the equipment.

[0046] Reference Figures 1-3 , Figure 5 In one embodiment, the stirring assembly includes a drive motor 301, stirring blades 302, and a transmission component 303;

[0047] The first receiving box 20 is provided with a first receiving groove 23, the drive motor 301 is disposed in the first receiving groove 23, the stirring fan blade 302 is located in the first receiving box 20 and is connected to the first output shaft 304 of the drive motor 301 extending into the first receiving box 20, and a second output shaft 305 is provided at the end of the drive motor 301 away from the first output shaft 304, the transmission component 303 is located outside the first receiving box 20 and is connected to the second output shaft 305, and the transmission component 303 is in contact with the sealing and sewage discharge mechanism 4.

[0048] In the above embodiment, the stirring assembly includes a drive motor 301, a stirring blade 302, and a transmission component 303. The drive motor 301 serves as the power source for the entire stirring assembly and is located in the first receiving groove 23 provided on the top of the first receiving box 20. The drive motor 301 is preferably a dual-output shaft motor, with a first output shaft 304 and a second output shaft 305 respectively provided at both ends. The stirring assembly is vertically arranged on the first receiving box 20, with its axis perpendicular to the top and bottom of the box. The first output shaft 304 extends toward the interior of the first receiving box 20 and is equipped with a stirring blade 302 at its end for stirring the sewage in the box to prevent the sediment from settling. The second output shaft 305 extends outward in the opposite direction for connecting to the external transmission component 303.

[0049] The stirring blades 302 are directly connected to the drive motor 301 via the first output shaft 304, ensuring high speed and efficient stirring effect. In actual operation, the rotation of the stirring blades 302 can not only stir up the sewage, but also clean the internal surface of the first container 20 with the help of the water flow, reducing the accumulation of dirt. At the same time, the transmission component 303 is located outside the first container 20 and connected to the second output shaft 305, which plays the role of transmitting power, so that the rotation of the drive motor 301 can control the action of the sealing sewage discharge mechanism 4.

[0050] The transmission component 303 is movably connected to the sealing and draining mechanism 4, so that when the drive motor 301 is running, the transmission component 303 can drive the sealing and draining mechanism 4 to move up and down, thereby controlling the opening and closing of the drain hole 22. The output shafts at both ends of the drive motor 301 have different speeds, with the first output shaft 304 having a significantly higher speed than the second output shaft 305. This means that the stirring blades 302 can stir the sewage more efficiently, while the transmission component 303 precisely controls the position change of the sealing and draining mechanism 4 at a slower speed, effectively ensuring the stirring efficiency and the accuracy and reliability of the operation of the sealing and draining mechanism 4.

[0051] Reference Figures 1-3 , Figure 5In one embodiment, the transmission component 303 includes a one-way bearing 3030 and a transmission module 3031. The one-way bearing 3030 is sleeved on the second output shaft 305, and the transmission module 3031 is sleeved on the side of the one-way bearing 3030 away from the second output shaft 305 and is movably connected to the sealing and draining mechanism 4. When the drive motor 301 rotates in the first direction, the second output shaft 305 drives the one-way bearing 3030 to rotate freely relative to the transmission module 3031. When the drive motor 301 rotates in the second direction, the second output shaft 305 drives the one-way bearing 3030 to be locked, so that the one-way bearing 3030 drives the transmission module 3031 to rotate synchronously.

[0052] In the above embodiment, the transmission component 303 includes a one-way bearing 3030 and a transmission module 3031. The one-way bearing 3030 allows free rotation in one direction and locks in the opposite direction. The one-way bearing 3030 is sleeved on the second output shaft 305 of the drive motor 301. When the drive motor 301 rotates in the first direction (i.e., the forward rotation direction of the drive motor 301), the second output shaft 305 drives the one-way bearing 3030 to rotate freely relative to the transmission module 3031. That is, the inner ring of the one-way bearing 3030 rotates with the second output shaft 305, but its outer ring remains relatively stationary, i.e., the so-called "slippage state." At this time, the transmission module 3031 is not affected in any way and remains in its original position. The transmission module 3031 is installed on the side of the one-way bearing 3030 away from the second output shaft 305 and is movably connected to the sealing and draining mechanism 4. The transmission module 3031 not only transmits power, but also ensures through a specific design that the sealing and draining mechanism 4 can move up and down accurately when needed. When the drive motor 301 rotates in the second direction, which is the reverse direction of the drive motor 301, the second output shaft 305 drives the one-way bearing 3030 to be locked, so that the one-way bearing 3030 drives the transmission module 3031 to rotate synchronously. That is, the inner and outer rings of the one-way bearing 3030 are locked, driving the entire transmission module 3031 to rotate synchronously, thereby pushing the sealing and draining mechanism 4 to move up and down.

[0053] A specified gap is left between the transmission module 3031 and the top of the drive motor 301. This specified gap is a clearance to accommodate the rotational movement of the transmission module 3031. This gap not only provides sufficient rotational space for the transmission module 3031, but also avoids the problem of failure or efficiency reduction that may be caused by mechanical collision. Therefore, by using the one-way bearing 3030 and the transmission module 3031, precise control of the sealing sewage discharge mechanism 4 is realized, which also improves the working efficiency and service life of the equipment and ensures the stability and safety of the system.

[0054] Reference Figures 1-5 In one embodiment, the transmission module 3031 includes a transmission body 3032 and a transmission inclined portion 3033 integrally connected to the transmission body 3032. The transmission body 3032 is sleeved on the one-way bearing 3030. The transmission inclined portion 3033 is disposed on the side of the transmission body 3032 away from the one-way bearing 3030 and is slidably connected to the sealing and draining mechanism 4. The transmission inclined portion 3033 extends spirally upward in a direction away from the drive motor 301.

[0055] In the above embodiment, the transmission module 3031 includes a transmission body 3032 and a transmission inclined section 3033. The transmission body 3032 is sleeved on the one-way bearing 3030 and tightly cooperates with the one-way bearing 3030, so that the transmission body 3032 is connected to the outer ring of the one-way bearing 3030, so that when the one-way bearing 3030 is locked, the entire transmission body 3032 can rotate synchronously. The transmission inclined section 3033 is located on the side of the transmission body 3032 away from the one-way bearing 3030, and is connected to the sealing and draining mechanism 4. The sliding connection is designed with the transmission inclined surface 3033 as a spiral upward inclined surface. That is, the surface in contact with the sealing and sewage discharge mechanism 4 and the transmission inclined surface 3033 is an arc-shaped curved surface, which ensures smooth and unobstructed sliding between the two. The spiral helix angle is preferably between 25° and 45°. In order to prevent the sealing and sewage discharge mechanism 4 from sliding excessively, limit baffles 3034 are respectively set at both ends of the transmission inclined surface 3033. These baffles play a role in limiting the position of the sealing and sewage discharge mechanism 4 and avoiding equipment failure or functional failure due to excessive sliding.

[0056] The side of the transmission inclined surface 3033 that contacts the sealing and draining mechanism 4 is a smooth spiral inclined surface. The transmission inclined surface 3033 extends upward in a counterclockwise spiral direction. This design is the same as the forward rotation direction of the drive motor 301, which means that when the drive motor 301 rotates forward, the sealing and draining mechanism 4 is located at the bottom of the transmission inclined surface 3033. When the drive motor 301 rotates in reverse, the sealing and draining mechanism 4 will gradually spiral along the transmission inclined surface 3033 to the top. At the same time, when rotating in reverse, the inner and outer rings of the one-way bearing 3030 are locked, driving the transmission module 3031 to rotate, thereby pushing the sealing and draining mechanism 4 to move up and down, realizing the opening and closing control of the drain hole 22. Through the special structure of the transmission inclined surface 3033, precise control of the sealing and draining mechanism 4 is achieved, which greatly improves the operating efficiency and stability of the equipment.

[0057] Reference Figures 1-5In one embodiment, the sealing and draining mechanism 4 includes a sealing telescopic assembly and a linkage rod 41. The sealing telescopic assembly is disposed on the first receiving box 20 and extends into the first receiving box 20, opposite to the drain hole 22. The linkage rod 41 is located outside the first receiving box 20 and connected to the sealing telescopic assembly. The end of the linkage rod 41 away from the sealing telescopic assembly is slidably connected to the transmission inclined surface 3033. When the drive motor 301 rotates in the first direction, the one-way bearing 3030 rotates freely relative to the transmission module 3031. Under the action of the sealing telescopic assembly, the linkage rod 41 remains in contact with the bottom of the transmission inclined surface 3033. The sealing telescopic assembly is in a retracted state and seals the drain hole 22. When the drive motor 301 rotates in the first direction, the one-way bearing 3030 rotates freely relative to the transmission module 3031. The linkage rod 41 remains in contact with the bottom of the transmission inclined surface 3033 under the action of the sealing telescopic assembly. The sealing telescopic assembly is in a retracted state and seals the drain hole 22. 1. When rotating in the second direction, the one-way bearing 3030 drives the transmission module 3031 to rotate synchronously. The transmission inclined section 3033 rotates with the transmission body 3032 and pushes the linkage rod 41 to rise along the spiral path of the transmission inclined section 3033. The linkage rod 41 drives the sealing telescopic assembly to extend to open the drain hole 22. When the linkage rod 41 rises to the preset highest point, the drive motor 301 stops rotating or rotates in the first direction. Under the action of the contraction force of the sealing telescopic assembly, the linkage rod 41 generates downward pressure along the transmission inclined section 3033, driving the transmission body 3032 to generate rotational torque. This torque causes the one-way bearing 3030 to rotate freely. As the transmission body 3032 rotates, the linkage rod 41 descends, and the sealing telescopic assembly contracts to the preset position to seal the drain hole 22.

[0058] In the above embodiments, the sealing and draining mechanism 4 mainly includes a sealing telescopic assembly and a linkage rod 41. The sealing telescopic assembly is a key component directly responsible for sealing the drain hole 22 at the bottom of the first receiving box 20. It is installed on the first receiving box 20 and extends towards the inside of the box, arranged opposite to the drain hole 22, ensuring that the sealing telescopic assembly can be accurately aligned with the drain hole 22. The central axis of the sealing telescopic assembly is parallel to that of the stirring assembly. The sealing telescopic assembly is installed perpendicular to the top and bottom of the first receiving box 20, so that it can move up and down when needed, thereby controlling the opening and closing state of the drain hole 22.

[0059] The linkage rod 41 serves as a bridge between the sealing telescopic assembly and the transmission module 3031. It is located outside the first receiving box 20 and connected to the sealing telescopic assembly. Preferably, the linkage rod 41 is perpendicular to the sealing telescopic assembly. One end of the linkage rod 41 is fixed to the top of the sealing telescopic assembly, and the other end is slidably connected to the transmission inclined surface 3033 in the transmission module 3031. This ensures that the linkage rod 41 is perpendicular to both the sealing telescopic assembly and the stirring assembly. At the same time, the linkage rod 41 maintains a certain distance from the first receiving box 20 and the second receiving groove 24 to ensure that it does not have unnecessary contact or friction with other components during movement. When the sealing telescopic assembly is at its lowest position, it fits tightly against the drain hole 22 to form an effective seal. When it moves upward, it gradually disengages from the drain hole 22, allowing sewage to flow out. By utilizing the ingenious combination of the sealing telescopic assembly and the linkage rod 41, precise control of the drain hole 22 is achieved, significantly improving the operating efficiency and stability of the equipment.

[0060] When the drive motor 301 rotates in the first direction (forward rotation), the one-way bearing 3030 rotates freely relative to the transmission module 3031. The linkage rod 41, under the action of the sealing telescopic assembly, remains in contact with the bottom of the transmission inclined section 3033. The sealing telescopic assembly is in a retracted state and seals the drain hole 22. When the drive motor 301 rotates in the second direction, the one-way bearing 3030 drives the transmission module 3031 to rotate synchronously. The transmission inclined section 3033 rotates with the transmission body 3032 and pushes the linkage rod 41 along the spiral path of the transmission inclined section 3033. As the path ascends, the linkage rod 41 drives the sealing telescopic assembly to extend and open the drain hole 22. When the linkage rod 41 rises to the preset highest point, the drive motor 301 stops rotating or rotates in the first direction. Under the action of the contraction force of the sealing telescopic assembly, the linkage rod 41 generates downward pressure along the transmission inclined surface 3033, driving the transmission body 3032 to generate rotational torque. This torque causes the one-way bearing 3030 to rotate freely. As the transmission body 3032 rotates, the linkage rod 41 descends, and the sealing telescopic assembly retracts to the preset position to seal the drain hole 22.

[0061] Reference Figures 1-5 In one embodiment, the sealing and draining mechanism 4 further includes a position detection component 42, which is disposed on the top of the first receiving box 20 and located on the upward path of the linkage rod 41. The position detection component 42 is used to detect the position of the linkage rod 41 and to control the opening and closing state of the sealing telescopic assembly and the drain hole 22 through the forward and reverse rotation mechanism of the drive motor 301.

[0062] In the above embodiment, the sealing and draining mechanism 4 also includes a position detection component 42, which is preferably a photoelectric switch (i.e., a photoelectric sensor). It is set on the top of the first receiving box 20 and located on the rising path of the linkage rod 41. Its main function is to monitor the position of the linkage rod 41 and control the forward and reverse rotation mechanism of the drive motor 301 through the control system (that is, the linkage movement between the stirring component and the sealing and draining mechanism 4), thereby realizing precise management of the opening and closing state of the sealing telescopic component and the drain hole 22. When the linkage rod 41 rises to the preset height with the rotation of the transmission inclined surface 3033, the photoelectric switch can sense this change and send a signal to the control system of the cleaning equipment. Based on the received information, the control system can determine whether the current sealing telescopic component has reached the predetermined height and then decide whether the direction of the drive motor 301 needs to be adjusted.

[0063] When the drive motor 301 reverses, the one-way bearing 3030 locks, causing the helical drive inclined section 3033 to rotate. This causes the linkage rod 41 to move upward along the drive inclined section. The upward movement of the linkage rod 41 directly drives the sealing telescopic assembly to move upward, gradually opening the drain hole 22 and allowing sewage to flow out. At the same time, the stirring blades 302 also rotate continuously, helping to agitate the sewage. When the linkage rod 41 rises to the position of the photoelectric switch, the photoelectric switch detects this situation and feeds a signal back to the control system. After receiving the signal, the control system commands the drive motor 301 to rotate forward again, causing the sealing telescopic assembly to return to its initial position and re-close the drain hole 22. Conversely, when the drive motor 301 rotates forward, the one-way bearing 3030 is in a free-rotating state, and the helical drive inclined section 3033 does not push the linkage rod 41 upward. Therefore, the sealing telescopic assembly remains in the closed position, ensuring that the drain hole 22 is sealed. At this time, the motor drives the stirring blades 302 to rotate, continuously agitating the sewage. By introducing the photoelectric switch as a position detection component 42, precise monitoring of the position of the sealing telescopic assembly is achieved, significantly improving the operating accuracy of the equipment.

[0064] Reference Figures 1-5 In one embodiment, the sealing telescopic assembly includes a sealing shaft 401, a telescopic component 402, and a sealing sleeve 403. The first receiving box 20 is provided with a second receiving groove 24. The sealing shaft 401 is disposed in the second receiving groove 24 and connected to the linkage rod 41. The end of the sealing shaft 401 away from the linkage rod 41 passes through the second receiving groove 24. The sealing sleeve 403 is located in the first receiving box 20 and is detachably connected to the end of the sealing shaft 401 away from the second receiving groove 24. The telescopic component 402 is disposed on the sealing shaft 401 and is located between the second receiving groove 24 and the sealing sleeve 403.

[0065] In the above embodiments, the sealing telescopic assembly includes a sealing shaft 401, a telescopic component 402, and a sealing sleeve 403. The sealing shaft 401 is installed in the second receiving groove 24 provided on the first receiving box 20 and is connected to the linkage rod 41. One end of the sealing shaft 401 is connected to the linkage rod 41, while the other end extends through the second receiving groove 24 into the interior of the first receiving box 20 to fix the sealing sleeve 403. The telescopic component 402 is located on the sealing shaft 401, specifically between the second receiving groove 24 and the sealing sleeve 403. It is mainly used to provide the sealing shaft 401 with an elastic telescopic force to ensure that the sealing sleeve 403 can smoothly open or close the drain hole 22 under the drive of the sealing shaft 401. The sealing sleeve 403 and the linkage rod 41 are arranged opposite to each other, that is, the sealing sleeve 403 is located at the bottom of the sealing shaft 401, while the linkage rod 41 is connected to the top of the sealing shaft 401. When the drive motor 301 works, the linkage rod 41 drives the sealing shaft 401 to move up and down, and the sealing shaft 401 then drives the sealing sleeve 403 to perform corresponding movements to complete the opening or closing action of the drain hole 22.

[0066] The sealing sleeve 403 is a key component directly responsible for sealing the drain hole 22. It is preferably made of silicone material. The sealing sleeve 403 and the sealing shaft 401 are detachably and tightly connected. The detachable connection is preferably a snap-fit ​​connection. The bottom of the sealing shaft 401 is designed with an I-shaped snap-fit ​​part, and the sealing sleeve 403 is provided with a corresponding I-shaped snap-fit ​​groove. The two match to achieve a firm and easy-to-disassemble connection. The sealing sleeve 403 forms an interference fit or lip seal structure in the drain hole 22. The sealing sleeve 403 consists of a sealing body 4030 and a sealing edge 4031. The sealing body 4030 is a conical shape with a decreasing diameter from top to bottom, which helps to better fit the drain hole 22 and form an effective seal. The sealing edge 4031 is integrally connected to the side of the upper part of the sealing body 4030, extends along the circumference of the entire sealing body 4030, and bends downward away from the sealing body 4030 to form a curved surface structure, which further enhances the sealing performance. Through the precise combination of the sealing shaft 401, the telescopic component 402 and the sealing sleeve 403, the effective sealing and flexible control of the drain hole 22 are achieved.

[0067] Reference Figures 1-5 In one embodiment, the telescopic component 402 includes a fixed sleeve 4020 and a telescopic body 4021. The fixed sleeve 4020 is located inside the first receiving box 20 and is sleeved on the end of the second receiving groove 24 away from the linkage rod 41. The sealing shaft 401 passes through the fixed sleeve 4020. A baffle 404 is provided at the end of the sealing shaft 401 near the sealing sleeve 403. The telescopic body 4021 is sleeved on the sealing shaft 401 and connected between the fixed sleeve 4020 and the baffle 404.

[0068] In the above embodiment, the telescopic component 402 includes a fixed sleeve 4020 and a telescopic body. The fixed sleeve 4020 is located inside the first receiving box 20 and is sleeved on the end of the second receiving groove 24 away from the linkage rod 41. It serves as a guide and support device for the sealing shaft 401, ensuring that the sealing shaft 401 can move smoothly up and down within the second receiving groove 24. The sealing shaft 401 passes through the fixed sleeve 4020, so that the sealing shaft 401 passes through the second receiving groove 24 and the fixed sleeve 4020 in sequence, and a baffle 404 is provided at the end of the sealing shaft 401 near the sealing sleeve 403. The telescopic body 4021 is preferably a spring, sleeved on the sealing shaft 401 and located between the fixed sleeve 4020 and the baffle 404. The function of the spring is to provide the necessary elastic support force for the sealing shaft 401, ensuring that the sealing sleeve 403 can tightly fit the drain hole 22 when needed, thereby achieving an effective sealing effect.

[0069] When the drive motor 301 rotates forward, the one-way bearing 3030 is in a free-rotating state, and the spiral drive inclined section 3033 is in the descending stage. At this time, the sealing shaft 401 is not affected by the power from the transmission module 3031 and remains stationary under the action of the spring. The sealing sleeve 403 tightly presses against the drain hole 22 to prevent sewage leakage. During the forward rotation of the motor, the stirring fan blade 302 is driven to rotate by the motor, continuously stirring the sewage to prevent dirt from settling. When the drive motor 301 rotates in reverse, the one-way bearing 3030 locks, driving the transmission module 3031 to rotate. The spiral drive inclined section 3033 begins to rise, pushing the linkage rod 41 to move upward. The linkage rod 41 pulls the sealing sleeve 403 upward through the sealing shaft 401, gradually opening the drain hole 22 and allowing sewage to flow out.

[0070] When the linkage rod 41 rises to a certain height, the photoelectric switch sends a signal to the control system. The control system then controls the drive motor 301 to rotate forward again, causing the sealing shaft 401 to return to its initial position under the action of the spring. The sealing sleeve 403 then presses against the drain hole 22 again, completing one full opening and closing cycle. During this process, the transmission module 3031 rotates freely relative to the inner ring through the outer ring of the one-way bearing 3030. That is, the linkage rod 41, through the action of the spring, causes the spiral drive inclined surface 3033 to rotate counterclockwise relative to the second output shaft 305. This allows the linkage rod 41 to slide smoothly downward on the spiral drive inclined surface under the tension of the spring, allowing the sealing sleeve 403 to press against the drain hole 22 again through the sealing shaft 401. This cycle continues. Through the ingenious combination of the fixed sleeve 4020 and the telescopic body 4021 (spring), effective support and precise control of the sealing shaft 401 are achieved, significantly improving the operating accuracy and stability of the equipment, ensuring the accurate opening and closing of the drain hole 22, and greatly improving the overall performance and reliability of the equipment.

[0071] Reference Figures 1-5In one embodiment, the sealing and draining mechanism 4 further includes a liquid level detection component 43, the fluid containing assembly 2 further includes a second containing tank 21, and the cleaning and stirring mechanism 3 further includes a water pump 31 and an air pump 32;

[0072] The liquid level detection component 43 is disposed on the first container 20. The liquid level detection component 43 is used to detect the liquid level of the first fluid in the first container 20. The second container 21 is disposed on the housing 1 and connected to the outside of the first container 20. The water pump 31 is disposed on the housing 1 and connected to the second container 21. The air pump 32 is disposed on the housing 1 and connected to the first container 20. The water pump 31 transports the second fluid in the second container 21 to the first container 20 through the air pump 32.

[0073] In the above embodiments, the sealing sewage discharge mechanism 4 further includes a liquid level detection component 43, the fluid containment component 2 further includes a second containment tank 21, and the cleaning and stirring mechanism 3 further includes a water pump 31 and an air pump 32; the liquid level detection component 43 is disposed on the first containment tank 20 and is used to monitor the liquid level height of sewage in the first containment tank 20 in real time. The liquid level detection component 43 is preferably a combination of a float and a Hall plate, wherein the float floats up and down with the change of sewage level. When the sewage reaches a preset position, the float will trigger the Hall plate to send a signal to the control system. The control system controls the drive motor 301 to reverse according to the received information, thereby starting the sewage discharge procedure;

[0074] The second container 21 is located on the housing 1 and connected to the outside of the first container 20. The first container 20 is located in the middle of the second container 21, and the two do not interfere with each other. It is used as a clean water tank and stores clean water or cleaning liquid (i.e., the second fluid). The water pump 31 is installed on the housing 1 and connected to the second container 21. It is responsible for transporting the clean water in the second container 21 to the key parts of the cleaning equipment, such as the roller brush, to complete the cleaning task. The air pump 32 is installed on the housing 1 and connected to the first container 20. When the drive motor 301 reverses to discharge sewage, the air pump 32 and the water pump 31 are started. The air pump 32 will create a certain negative pressure in the first container 20, so that the sewage recovered from the roller brush or other cleaning parts can smoothly enter the first container 20. Then, through multiple cycles of sewage discharge and cleaning, the sewage tank achieves a self-cleaning effect, and the sewage is also automatically discharged.

[0075] The ingenious combination of a liquid level detection device, a second containment tank 21, a water pump 31, and an air pump 32 enables efficient management of wastewater discharge and the cleaning process. The liquid level detection device can monitor the wastewater level in real time, ensuring that the discharge procedure is initiated at the appropriate time to prevent wastewater overflow. The second containment tank 21 serves as a clean water source, providing a stable supply of cleaning water and guaranteeing the cleaning effect. The coordinated work of the water pump 31 and the air pump 32 not only ensures the supply of cleaning water but also effectively collects the wastewater after use, reducing the need for manual intervention. This not only simplifies the operation process and improves work efficiency but also reduces maintenance costs and enhances the reliability and service life of the system.

[0076] Reference Figure 1 , Figure 5 This embodiment also discloses a cleaning device, including the self-cleaning sewage discharge device described in any of the above embodiments. The cleaning device integrating the self-cleaning sewage discharge device has the functions of self-cleaning sewage tank and automatic sewage discharge. That is, the automatic closing / opening process of the sealing sewage discharge mechanism 4 and the sewage discharge hole 22 is completed by the mechanical linkage of the stirring component (forward and reverse rotation mechanism), realizing the automatic opening and closing of the sewage discharge hole 22 without manual operation of sewage discharge. At the same time, the stirring component continuously stirs the sewage, effectively reducing dirt deposition, reducing the frequency of manual cleaning, reducing the risk of residual sewage leakage, and indirectly reducing the probability of environmental pollution, thereby improving the hygiene performance and service life of the equipment.
