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

The receiving component includes a first receiving tank and a second receiving tank disposed within the first receiving tank. The driving mechanism is disposed on the second receiving tank, and the elastic stirring mechanism is located within the first receiving tank and movably connected to the driving mechanism.

[0044] Reference Figure 1 , Figures 7-8 This embodiment provides a self-cleaning sewage discharge device, including a receiving component 1, a driving mechanism 2, an elastic stirring mechanism 3, and an elastic sealing mechanism 4;

[0045] The containing assembly 1 includes a first containing box 10 and a second containing box 11 disposed within the first containing box 10; the driving mechanism 2 is disposed on the second containing box 11; the elastic stirring mechanism 3 is located within the first containing box 10 and is movably connected to the driving mechanism 2; the driving mechanism 2 is used to drive the elastic stirring mechanism 3 to perform compound motion and stir the first fluid in the first containing box 10.

[0046] The first receiving box 10 is provided with a drain hole 13 arranged opposite to the elastic stirring mechanism 3. The elastic sealing mechanism 4 is disposed in the drain hole 13. The elastic sealing mechanism 4 is used to control the opening and closing state of the drain hole 13 by the movement of the elastic stirring mechanism 3. When the driving mechanism 2 rotates along the first direction, the driving mechanism 2 drives the elastic stirring mechanism 3 to rotate synchronously. When the driving mechanism 2 rotates along the second direction, the driving mechanism 2 drives the elastic stirring mechanism 3 to rotate synchronously, and at the same time drives the elastic stirring mechanism 3 to move linearly towards the elastic sealing mechanism 4. The first direction and the second direction are opposite to each other.

[0047] In the above embodiments, the self-cleaning sewage discharge device includes a receiving component 1, a driving mechanism 2, an elastic stirring mechanism 3, and an elastic sealing mechanism 4. The receiving component 1 consists of a first receiving tank 10 and a second receiving tank 11 disposed inside it. The first receiving tank 10 is used to hold sewage (i.e., the first fluid). The second receiving tank 11 serves as a support structure and is fixedly installed inside the first receiving tank 10 to support and fix the driving mechanism 2. The driving mechanism 2 is disposed on the second receiving tank 11 and its function is to provide power output and drive the elastic stirring mechanism 3, which is movably connected to it, to perform corresponding compound movements through rotational movements in both forward and reverse directions.

[0048] The elastic stirring mechanism 3 is located inside the first receiving tank 10 and is connected to the drive mechanism 2. It can rotate under the drive of the drive mechanism 2, and can also move linearly in the axial direction when rotating in a specific direction, thus completing the dual functions of stirring and triggering sewage discharge. The compound motion includes rotation and rotation plus linear motion. The first direction is forward rotation and the second direction is reverse rotation. When the drive mechanism 2 rotates forward, the elastic stirring mechanism 3 only rotates and remains in the retracted state to stir the sewage in the first receiving tank 10 to achieve self-cleaning. When the drive mechanism 2 rotates in reverse, the elastic stirring mechanism 3 moves linearly downward while rotating and enters the extended state.

[0049] The bottom of the first receiving tank 10 is provided with a drain hole 13, which is arranged opposite to the elastic stirring mechanism 3 and serves as a channel for sewage discharge. The elastic sealing mechanism 4 is located inside the drain hole 13. Its function is to automatically control the opening and closing state of the drain hole 13 according to the position change of the elastic stirring mechanism 3. When the elastic stirring mechanism 3 is in the retracted state, it does not contact the elastic sealing mechanism 4. The elastic sealing mechanism 4 relies on its own elasticity to maintain a sealed fit with the drain hole 13, keeping the drain hole 13 in a closed state to prevent leakage. When the elastic stirring mechanism 3 extends under the reverse drive and acts on the elastic sealing mechanism 4, it causes the elastic sealing mechanism 4 to connect the first receiving tank 10 with the drain hole 13, thereby opening the drain hole 13 and realizing sewage discharge. When the waiting time for water discharge is up, the drive mechanism 2 rotates forward again, the elastic stirring mechanism 3 retracts under its own elasticity, and the elastic sealing mechanism 4 re-seales with the drain hole 13 under its own elasticity. This forward and reverse cycle of sewage discharge and stirring continues. The flexible stirring mechanism 3 achieves compound motion through forward and reverse rotation of the drive mechanism 2: when rotating forward, it only rotates and stirs the sewage to complete self-cleaning; when rotating in reverse, it rotates and moves linearly at the same time, triggering the flexible sealing mechanism 4 to open the drain hole 13. After draining, it automatically resets the seal, eliminating the need for manual intervention in draining and cleaning, reducing labor costs, avoiding sewage overflow caused by operational errors, reducing the risk of environmental pollution, reducing stain residue and mold growth, and improving the hygiene performance and service life of the equipment.

[0050] Reference Figures 1-2 , Figures 7-8 In one embodiment, the drive mechanism 2 includes a drive body component 20, a drive shaft 21, and a transmission component 22;

[0051] The driving main component 20 is disposed inside the second receiving box 11. The driving shaft 21 is disposed at one end of the driving main component 20 and extends through the bottom of the second receiving box 11 toward the first receiving box 10. The elastic stirring mechanism 3 is disposed at the end of the driving shaft 21 away from the driving main component 20. The transmission member 22 is disposed on the driving shaft 21. The transmission member 22 is located between the elastic stirring mechanism 3 and the bottom of the second receiving box 11, and the transmission member 22 is in contact with the elastic stirring mechanism 3.

[0052] In the above embodiment, the driving mechanism 2 includes a driving main body member 20, a driving shaft 21 and a transmission member 22. The driving main body member 20 is installed inside the second accommodating box 11. The driving shaft 21, as a key component for transmitting power, is connected to the driving main body member 20 at one end and extends through the bottom of the second accommodating box 11 to the inside of the first accommodating box 10 at the other end. An elastic stirring mechanism 3 is connected to the end of the driving shaft 21. The transmission member 22 is arranged on the driving shaft 21 and is located between the elastic stirring mechanism 3 and the bottom of the second accommodating box 11. Its shape is similar to a "C" - shaped structure, and the central part is fixed on the driving shaft 21, ensuring that the transmission member 22 can rotate synchronously with the driving shaft 21. A transmission slot is provided on the driving shaft 21, which is located between the transmission member 22 and the elastic stirring mechanism 3, and a transmission limiting member is installed therein to limit and fix the position of the transmission member 22, preventing unnecessary movement during operation. The two ends of the transmission member 22 directly contact the upper surface of the elastic stirring mechanism 3.

[0053] When the driving shaft 21 drives the transmission member 22 to rotate, its two ends can slide correspondingly on the surface of the elastic stirring mechanism 3, thereby effectively driving the elastic stirring mechanism 3 to complete the required movement. When the driving mechanism 2 rotates forward or backward, the transmission member 22 guides the elastic stirring mechanism 3 to perform rotational or rotational plus linear compound movement according to its preset path (such as a plane, a spiral surface 3041, etc.). The close contact between the transmission member 22 and the elastic stirring mechanism 3 enables the power of the driving mechanism 2 to be efficiently transmitted to the stirring mechanism, ensuring accurate stirring and sewage discharge operations under different working conditions.

[0054] Refer to Figures 1-2 、 Figures 7-8 In one embodiment, the elastic stirring mechanism 3 includes a stirring sliding component 30. The stirring sliding component 30 includes a connecting portion 301, a sliding portion 302 and a plurality of stirring fan blades 303.

[0055] The connecting portion 301 is movably connected to the driving shaft 21. The sliding portion 302 is connected to the side of the connecting portion 301 away from the driving shaft 21. A plurality of the stirring fan blades 303 are arranged at intervals on the side of the sliding portion 302 away from the connecting portion 301. A plurality of sliding surfaces 304 are provided on the sliding portion 302, and the transmission member 22 is slidably connected to the sliding surfaces 304.

[0056] In the above embodiment, the elastic stirring mechanism 3 includes a stirring sliding component 30, which is composed of a connecting part 301, a sliding part 302 and multiple stirring fan blades 303. The connecting part 301 serves as the movable connection point between the entire stirring sliding component 30 and the drive shaft 21, ensuring that the stirring sliding component 30 can perform corresponding rotational movements according to the rotation of the drive shaft 21. The connecting part 301 is designed as a circular structure and is directly installed on the drive shaft 21. The sliding part 302 is located on the side of the connecting part 301 away from the drive shaft 21. The sliding part 302 is also a circular structure. On the side of the sliding part 302 away from the connecting part 301, multiple stirring fan blades 303 are arranged at intervals for agitating the fluid in the first accommodation box 10. The connecting part 301, the sliding part 302 and the stirring fan blades 303 are designed as an integral part. Two sliding surfaces 304 are provided on the sliding part 302. These two sliding surfaces 304 are located on the same diameter and have the same extension direction, ensuring that both ends of the transmission part 22 can slide smoothly on these two sliding surfaces 304. The transmission part 22 is a "C"-shaped structure, and its two ends are respectively in contact with the two sliding surfaces 304. When the drive shaft 21 drives the transmission part 22 to rotate, the two ends of the transmission part 22 move along the sliding surfaces 304, prompting the sliding part 302 and the stirring fan blades 303 thereon to perform the required rotational or rotational plus linear motion. By providing special sliding surfaces 304 on the sliding part 302, it is ensured that the transmission part 22 can accurately control the actions of the stirring sliding component 30, making the stirring and sewage discharge processes more efficient and precise.

[0057] Refer to Figures 1-2 , Figures 7-8In one embodiment, the sliding surface 304 includes a first plane 3040, a helical surface 3041, and a second plane 3042. A partition block 305 is provided on the sliding part 302. The first plane 3040 is disposed on one side of the partition block 305. The helical surface 3041 is disposed at the end of the first plane 3040 away from the partition block 305, and the helical surface 3041 is inclined downwards in a direction away from the driving main component 20. The second plane 3042 is disposed at the end of the helical surface 3041 away from the first plane 3040, and the end of the second plane 3042 away from the helical surface 3041 forms a blocking plane 3043 perpendicular to the second plane 3042. When the driving main component 20 drives the transmission member 22 to rotate along the first direction, the transmission member 22 abuts against the second plane 3042 and contacts the blocking plane 3043, and the transmission member 22 drives the sliding part 302 to rotate. The stirring sliding assembly 30 rotates synchronously, and the elastic sealing mechanism 4 seals the drain hole 13. When the driving main component 20 drives the transmission component 22 to rotate in the second direction, the transmission component 22 slides spirally upward from the second plane 3042 through the spiral curved surface 3041 to the first plane 3040 and contacts the partition block 305. The transmission component 22 drives the stirring sliding assembly 30 to rotate synchronously and simultaneously presses the stirring sliding assembly 30 to move linearly towards the elastic sealing mechanism 4. The elastic sealing mechanism 4 opens the drain hole 13. When the elastic sealing mechanism 4 reaches the preset drainage time, the driving main component 20 drives the transmission component 22 to rotate in the first direction. The transmission component 22 slides spirally downward from the first plane 3040 through the spiral curved surface 3041 to the second plane 3042 and contacts the barrier plane 3043. The elastic sealing mechanism 4 seals the drain hole 13.

[0058] In the above embodiment, the sliding surface 304 includes a first plane 3040, a spiral surface 3041, and a second plane 3042. The sliding part 302 is provided with a partition block 305. The first plane 3040 is disposed on one side of the partition block 305, while the spiral surface 3041 is located at the end of the first plane 3040 away from the partition block 305 and is arranged downwardly in a direction away from the driving main body component 20. The second plane 3042 is located at the end of the spiral surface 3041 away from the first plane 3040, and a blocking plane 3043 perpendicular to the plane is formed at the end of the second plane 3042 away from the spiral surface 3041, so that the transmission component 22 can move along a specific path, thereby precisely controlling the action of the stirring sliding assembly 30.

[0059] When the driving main component 20 drives the transmission component 22 to rotate in the first direction (forward rotation), the transmission component 22 abuts against the second plane 3042 and contacts the blocking plane 3043. At this time, the transmission component 22 only drives the stirring sliding assembly 30 to rotate synchronously, and the elastic sealing mechanism 4 maintains a sealed state with the drain hole 13 to prevent sewage leakage. The second plane 3042 is a plane formed by the sliding part 302 being recessed from the top downwards, and the first plane 3040 serves as the top plane of the sliding part 302. The first plane 3040 and the second plane 3042 are parallel to each other. When the driving main component 20 drives the transmission component 22 to rotate in the second direction (reverse rotation), the transmission component 22 slides from the second plane 3042 upwards through the spiral curved surface 3041 to the first plane 3040, and finally contacts the partition block 305. During this process, in addition to rotation, the transmission component 22 also presses the stirring sliding assembly 30, causing it to move linearly towards the elastic sealing mechanism 4, opening the drain hole 13, and realizing the sewage leakage. In addition, the blocking plane 3043 serves as one side of the block that restricts the movement of the transmission component 22, ensuring that the transmission component 22 does not exceed the predetermined range of motion. Furthermore, when the elastic sealing mechanism 4 reaches the preset drainage time, the driving main component 20 drives the transmission component 22 to rotate along the first direction. The transmission component 22 slides spirally downward from the first plane 3040 through the spiral curved surface 3041 to the second plane 3042 and contacts the blocking plane 3043. The elastic sealing mechanism 4 seals the drain hole 13. The preset drainage time is detected by setting a timer or time relay near the elastic sealing mechanism 4. When the set time is reached, the driving main component 20 is triggered to reverse. This timer or time relay can be integrated into the control circuit board, which is located on the outside of the second housing 11 in a convenient maintenance position. In this way, the stirring sliding assembly 30 is ensured to operate in the expected manner, achieving both efficient stirring and the ability to quickly open the drain hole 13 for drainage when needed.

[0060] Reference Figures 1-4 , Figures 7-8 In one embodiment, the elastic stirring mechanism 3 further includes a pressing member 31, a first elastic member 32, and a limiting ring 33. The pressing member 31 is disposed on the side of the sliding part 302 away from the transmission member 22. The pressing member 31, the sliding part 302, and the connecting part 301 together form a receiving cavity 34. The drive shaft 21 passes through the connecting part 301 and is located in the receiving cavity 34. The first elastic member 32 and the limiting ring 33 are respectively located in the receiving cavity 34. The limiting ring 33 is engaged in the slot of the drive shaft 21. The first elastic member 32 is sleeved on the drive shaft 21, and one end of the first elastic member 32 abuts against the connecting part 301, and the other end abuts against the limiting ring 33.

[0061] In the above embodiment, the elastic stirring mechanism 3 further includes a pressing member 31, a first elastic member 32, and a limiting ring 33. The pressing member 31 is located on the side of the sliding part 302 away from the transmission member 22, and together with the sliding part 302 and the connecting part 301, they form a receiving cavity 34. The receiving cavity 34 provides space for the drive shaft 21, so that the drive shaft 21 can pass through the connecting part 301 and be located inside the receiving cavity 34. Inside the receiving cavity 34, the limiting ring 33 is fixed in the slot on the drive shaft 21. The first elastic member 32 is sleeved on the drive shaft 21, with one end abutting against the connecting part 301 and the other end abutting against the limiting ring 33. The first elastic member 32 can provide the necessary elastic force when the elastic stirring mechanism 3 extends or retracts.

[0062] When the transmission component 22 is located on the second plane 3042, the first elastic component 32 is in an uncompressed state, which means that the elastic stirring mechanism 3 remains retracted and does not apply additional pressure to the elastic sealing mechanism 4, and the drain hole 13 remains closed. When the transmission component 22 moves to the first plane 3040, the first elastic component 32 is compressed as the transmission component 22 pushes the sliding part 302 downward, thereby generating a reverse force. During this process, the pressing component 31 directly contacts the elastic sealing mechanism 4, forcing it to open the drain hole 13. In addition, the inner wall of the connecting part 301 and the bottom of the pressing component 31 form a certain gap with the drive shaft 21, which not only provides room for the first elastic component 32 to move, but also avoids direct friction between the components. Through the pressing component 31, the first elastic component 32 and the limiting ring 33, it is ensured that the elastic stirring mechanism 3 can operate efficiently in different working states (such as stirring and draining).

[0063] Reference Figure 1 -- Figure 8 In one embodiment, the drain hole 13 includes a sealing mounting hole 130 and a drain through hole 131 communicating with the sealing mounting hole 130. The elastic sealing mechanism 4 includes a sealing bracket 40 and a mounting cylinder 41. The mounting cylinder 41 is disposed on the side of the sealing bracket 40 away from the elastic stirring mechanism 3. The sealing bracket 40 is connected inside the sealing mounting hole 130, and the end of the mounting cylinder 41 away from the sealing bracket 40 abuts against the bottom of the sealing mounting hole 130. The sealing bracket 40 is provided with a pressing through hole 42 communicating with the mounting cylinder 41. The pressing through hole 42 is arranged opposite to the drain through hole 131.

[0064] In the above embodiment, the drain hole 13 includes a sealing mounting hole 130 and a drain through hole 131 connected thereto. The sealing mounting hole 130 is a strip-shaped hole located at the bottom of the first receiving box 10. The drain through hole 131 is a circular structure located at the middle of the bottom of the sealing mounting hole 130. Two connecting posts 132 are provided at the bottom of the sealing mounting hole 130, which are located on both sides of the drain through hole 131. The elastic sealing mechanism 4 consists of a sealing bracket 40 and a mounting cylinder 41. The connecting posts 132 provide fixing points for the sealing bracket 40. The sealing bracket 40 is connected to the connecting posts 132 by bolts, so that its top plane is kept on the same horizontal plane as the top of the sealing mounting hole 130.

[0065] The placement cylinder 41 is located on the side of the sealing bracket 40 away from the elastic stirring mechanism 3. One end of the cylinder abuts against the bottom of the sealing placement hole 130, and the other end is connected to the sealing bracket 40. Both the placement cylinder 41 and the sealing bracket 40 are integrally molded. The diameter of the placement cylinder 41 is larger than the diameter of the drain hole 131. The sealing bracket 40 is provided with a pressing through hole 42, which is arranged opposite to the drain hole 131. Both are circular structures. The pressing through hole 42 and the drain hole 131 are located at both ends of the placement cylinder 41, so that sewage can enter through the pressing through hole 42, pass through the placement cylinder 41, and finally be discharged through the drain hole 131. This allows the sewage to complete the discharge process with minimal resistance, avoiding clogging problems.

[0066] Reference Figure 1 -- Figure 8 In one embodiment, the elastic sealing mechanism 4 further includes an elastic sealing valve 43. The elastic sealing valve 43 includes a support frame 430, a second elastic element 431, and a switch sealing ring 432 located inside the mounting cylinder 41. One end of the second elastic element 431 is connected to the support frame 430, and the other end abuts against the bottom of the sealing mounting hole 130. A pressing block 433 is provided on the side of the support frame 430 away from the second elastic element 431. The pressing block 433 is located inside the pressing through hole 42. The switch sealing ring 432 is sleeved on the pressing block 433 and is located on the side of the support frame 430 away from the second elastic element 431. The switch sealing ring 432 is in contact with the top wall of the mounting cylinder 41.

[0067] In the above embodiment, the elastic sealing mechanism 4 further includes an elastic sealing valve 43, which is composed of a support frame 430, a second elastic element 431, and a switch sealing ring 432. The support frame 430 is located inside the housing cylinder 41, and one end of it contacts the bottom of the sealing housing hole 130 through the second elastic element 431, while the other end is provided with a pressing block 433. The pressing block 433 is placed in the pressing through hole 42 on the sealing bracket 40. The support frame 430 has a circular structure with a diameter larger than the diameter of the pressing through hole 42. One end of the second elastic element 431 is connected to the support frame 430, and the other end abuts against the bottom of the sealing housing hole 130, providing the necessary elastic restoring force so that when there is no external force, the support frame 430 and the switch sealing ring 432 on it can fit tightly against the top wall of the housing cylinder 41 to maintain a sealed state.

[0068] The switch sealing ring 432 is sleeved on the pressing block 433 and located on the side of the support frame 430 away from the second elastic member 431. Its diameter is larger than the diameter of the pressing block 433 and the pressing through hole 42, which ensures that sewage can be effectively prevented from flowing into the placement cylinder 41 from the pressing through hole 42 when the switch is closed. The pressing block 433 and the support frame 430 are integrated and designed as a cross structure. In addition, a similar top pressing block is also provided at the bottom of the pressing member 31. The two have the same structure and are both cross-shaped designs.

[0069] When the pressing block 433 is not pressed by the pressing member 31 of the elastic stirring mechanism 3, the switch sealing ring 432 is tightly attached to the top wall of the placement cylinder 41 by the force of the second elastic member 431, so that the pressing through hole 42 and the placement cylinder 41 are not connected, preventing sewage leakage; when the drive main component 20 reverses and the elastic stirring mechanism 3 moves downward, the pressing member 31 passes through the pressing through hole 42 and presses the pressing block 433, the support frame 430 moves downward accordingly, causing the switch sealing ring 432 to detach from the top wall of the placement cylinder 41. At this time, the pressing through hole 42 and the placement cylinder 41 are no longer connected. When the system is in a connected state, sewage can enter the housing cylinder 41 through the pressing through hole 42 and then be discharged through the sewage discharge through hole 131. After the preset drainage time is reached, the drive main component 20 rotates forward again, the pressing component 31 releases the pressing block 433, and the switch sealing ring 432 is tightly attached to the top wall of the housing cylinder 41 again under the action of the second elastic component 431, restoring the sealing state. By using the combination of the support frame 430, the second elastic component 431 and the switch sealing ring 432, it is ensured that the sealing mechanism can tightly seal the pressing through hole 42 when sewage is not being discharged, preventing sewage leakage.

[0070] Reference Figures 1-2 , Figures 7-8In one embodiment, the drive main component 20 includes a drive motor 201, a motor bracket 202, and a motor sealing ring 203. A bracket connecting column is provided inside the second receiving box 11. The motor bracket 202 is disposed at one end of the drive motor 201 away from the drive shaft 21, and the side of the motor bracket 202 away from the drive motor 201 is connected to the bracket connecting column. The motor sealing ring 203 is disposed on the side of the drive motor 201 away from the motor bracket 202 and fits against the bottom of the second receiving box 11. The drive shaft 21 passes through the motor sealing ring 203.

[0071] In the above embodiment, the drive main component 20 includes a drive motor 201, a motor bracket 202, and a motor sealing ring 203. The drive motor 201 is installed inside the second housing 11 and provides the necessary rotational power to the elastic stirring mechanism 3 through the drive shaft 21. The motor bracket 202 is located at the end of the drive motor 201 away from the drive shaft 21, and is connected to the bracket connecting column set inside the second housing 11 through its other side. The motor sealing ring 203 is located on the side of the drive motor 201 away from the motor bracket 202 and is tightly fitted to the bottom of the second housing 11. The motor sealing ring 203 is installed around the drive shaft 21 to ensure that the drive shaft 21 can pass smoothly through its structure, while preventing any external liquid (such as sewage) from seeping into the interior of the second housing 11. The drive shaft 21 passes through the bottom of the second housing 11 and the motor sealing ring 203 in sequence and is connected to the drive motor 201. By using the motor sealing ring 203, sewage is effectively isolated from the drive motor 201, which greatly improves the safety and reliability of the equipment and extends the service life of the motor and other electronic components.

[0072] Reference Figures 1-2 , Figures 7-8 In one embodiment, the receiving assembly 1 further includes a third receiving box 12, which is connected to the side of the first receiving box 10 away from the second receiving box 11, and the third receiving box 12 extends a specified distance along the side of the first receiving box 10.

[0073] In the above embodiment, the containing component 1 further includes a third containing tank 12, which is mainly used to store clean water so that the inside of the first containing tank 10 can be circulated and flushed through pipes and valves when needed. The third containing tank 12 is connected to the side of the first containing tank 10 away from the second containing tank 11 and extends a specified distance along the side of the first containing tank 10. The first containing tank 10 is fitted inside the third containing tank 12, so that there is a certain gap between the sides and front end of the first containing tank 10 and the third containing tank 12. The bottom structure of the two containing tanks consists of a straight plate and an inclined plate. The drain hole 13 is located between the straight plate and the inclined plate. The straight plate provides a flat base, while the inclined plate helps to guide the sewage to flow smoothly to the drain hole 13, ensuring that the sewage can be discharged efficiently without residue, realizing an efficient self-cleaning function, ensuring the cleanliness of the inside of the equipment, and reducing the risk of bacterial growth.

[0074] Reference Figures 1-2 , Figures 7-8 This embodiment also discloses a cleaning device, including the self-cleaning sewage discharge device described in any of the above embodiments. The elastic stirring mechanism 3 achieves compound motion through the forward and reverse rotation of the drive mechanism 2: when rotating forward, it only rotates and stirs the sewage to complete self-cleaning; when rotating in reverse, it rotates and moves linearly at the same time, triggering the elastic sealing mechanism 4 to open the sewage discharge hole 13. After sewage discharge, it automatically resets and seals, eliminating the need for manual intervention in sewage discharge and cleaning, reducing labor costs, avoiding sewage overflow caused by operational errors, reducing the risk of environmental pollution, reducing stain residue and mold growth, and improving the hygiene performance and service life of the equipment.
