Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, specifically a sewage pumping device for a cleaning robot. Background Technology

[0002] Currently, commercial cleaning robots with wet mopping functions generate wastewater when cleaning the mop. This wastewater is typically generated in a wastewater tank, which the robot then pumps into the wastewater container. Most commercial cleaning robots on the market use either diaphragm pumps or peristaltic pumps to pump this wastewater. Both diaphragm pumps and wastewater pumps have the following problems:

[0003] It cannot be placed directly into water because it has poor water-resistant properties.

[0004] If left for a long time, the sludge in the sewage box will dry out. Since the blades inside the peristaltic pump or diaphragm pump are very thin, the peristaltic pump or diaphragm pump will not be able to open after the water stains have dried out over a long period of time, resulting in the inability to pump sewage. This will cause the sewage box to fill up, sewage to overflow, and water leakage to occur, contaminating the cleaned path. To address this, we propose a sewage pumping device for cleaning robots. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater pumping device for cleaning robots to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage pumping device for a cleaning robot, comprising a pumping housing mechanism, wherein multiple sets of staggered fixed seats are fixedly connected to the outside of the pumping housing mechanism, and the fixed seats are provided with through mounting grooves for threaded locking; a drive motor is fixedly installed on the top of the inner wall of the pumping housing mechanism, and a drainage mechanism for sewage discharge is fixedly installed on the bottom of the inner wall of the pumping housing mechanism; and a drive opening and closing mechanism for controlling the opening and closing of the drainage mechanism is fixedly connected to the output end of the drive motor.

[0007] Furthermore, the water pumping housing mechanism includes a mounting base, a connecting pipe, a water inlet groove, and a limiting groove. The drive motor is fixedly installed inside the mounting base. The bottom of the mounting base is fixedly connected to the connecting pipe. Two sets of water inlet grooves are opened through the outer wall of the connecting pipe. A limiting groove is opened inside the connecting pipe.

[0008] Furthermore, the drainage mechanism includes a drain pipe, a first connecting seat, a limiting block, and a drainage groove. The drain pipe is fixedly installed at the bottom of the inner wall of the connecting pipe, and the top of the drain pipe is fixedly connected to the first connecting seat. The limiting block, which is inserted into the limiting groove, is fixedly connected to the outside of the first connecting seat. Two sets of fan-shaped drainage grooves are opened through the limiting block at the position corresponding to the water inlet groove.

[0009] Furthermore, the drive opening and closing mechanism includes a connecting block, a second connecting seat, and a sealing block. The output end of the drive motor is fixedly connected to the connecting block, the bottom of the connecting block is fixedly connected to the second connecting seat, and a sealing block for sealing the drainage groove is fixedly connected to the second connecting seat.

[0011] Furthermore, the bottom of the inner wall of the water inlet tank is inclined, and a rubber pad is fixedly connected to the bottom of the sealing block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a sewage pumping device for a cleaning robot, including a pumping housing mechanism 1. The pumping housing mechanism 1 is externally fixedly connected to multiple sets of staggered fixed seats 2. The fixed seats 2 are provided with through mounting grooves 6 for threaded locking. A drive motor 3 is fixedly installed on the top of the inner wall of the pumping housing mechanism 1. A drainage mechanism 5 for sewage discharge is fixedly installed on the bottom of the inner wall of the pumping housing mechanism 1. The output end of the drive motor 3 is fixedly connected to a drive opening and closing mechanism 4 for controlling the opening and closing of the drainage mechanism 5.

[0021] The pumping housing mechanism 1, fixed base 2, and mounting groove 6 are designed to work together to allow the pumping housing mechanism 1 to be directly installed in the water box. When sewage needs to be pumped out, the drive motor 3 operates, which drives the drive opening and closing mechanism 4 to rotate, thereby opening the drainage mechanism 5. This allows sewage to be discharged through the pumping housing mechanism 1 and the drainage mechanism 5. This design can replace the commonly used diaphragm pump or peristaltic pump, and can be directly placed in the water. Moreover, the use is not affected after the mud in the sewage dries.

[0022] Please see Figure 1 and Figure 2 The water pumping housing mechanism 1 includes a mounting base 7, a connecting pipe 8, a water inlet groove 9, and a limiting groove 10. The drive motor 3 is fixedly installed inside the mounting base 7. The bottom of the mounting base 7 is fixedly connected to the connecting pipe 8. Two sets of water inlet grooves 9 are opened through the outer wall of the connecting pipe 8. The limiting groove 10 is opened inside the connecting pipe 8. The bottom of the inner wall of the water inlet groove 9 is inclined.

[0023] The mounting base 7 and connecting pipe 8 can be used to fix the drive motor 3, drainage mechanism 5 and drive opening and closing mechanism 4. The sewage to be pumped out can be put into the water inlet 9 and discharged through the drainage mechanism 5. The bottom of the inner wall of the water inlet 9 is inclined to facilitate the sewage to enter the drainage mechanism 5. The limiting groove 10 on the inner wall of the connecting pipe 8 facilitates the fixed installation of the drainage mechanism 5.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5The drainage mechanism 5 includes a drain pipe 11, a first connecting seat 12, a limiting block 13, and a drainage groove 14. The drain pipe 11 is fixedly installed at the bottom of the inner wall of the connecting pipe 8. The top of the drain pipe 11 is fixedly connected to the first connecting seat 12. The outside of the first connecting seat 12 is fixedly connected to the limiting block 13, which is inserted into the limiting groove 10. Two sets of fan-shaped drainage grooves 14 are opened through the limiting block 13 at the position corresponding to the water inlet groove 9.

[0025] The drain pipe 11 is fixedly installed at the bottom of the connecting pipe 8. Then, the outer wall of the first connecting seat 12 is fixedly connected with a limiting block 13 that cooperates with the limiting groove 10 to fix the position of the first connecting seat 12. After the drive opening and closing mechanism 4 is misaligned with the drain trough 14 and the sewage can be discharged through the inlet trough 9, the drain trough 14 and the drain pipe 11.

[0026] Please see Figures 1-5 The drive opening and closing mechanism 4 includes a connecting block 15, a second connecting seat 16, and a sealing block 17. The output end of the drive motor 3 is fixedly connected to the connecting block 15. The bottom of the connecting block 15 is fixedly connected to the second connecting seat 16. The second connecting seat 16 is fixedly connected to an 8-shaped sealing block 17 that seals the drainage groove 14. The bottom of the sealing block 17 is fixedly connected to a rubber pad.

[0027] When drainage is required, the drive motor 3 drives the connecting block 15, the second connecting seat 16 and the sealing block 17 to rotate, so that the figure-eight sealing block 17 is misaligned with the drainage trough 14, thereby allowing sewage to be discharged quickly. When the drainage trough 14 needs to be sealed, the drive motor 3 drives the sealing block 17 to correspond with the drainage trough 14, so that it can cooperate with the rubber gasket to complete the sealing of the drainage trough 14.

[0028] Please see Figure 1 and Figure 4 The connecting block 15 is externally fixedly connected with two sets of rubber sealing rings 18 that fit against the inner wall of the connecting pipe 8. The two sets of rubber sealing rings 18 can prevent sewage backflow from contaminating the drive motor 3.

[0029] In use, firstly, the pumping housing mechanism 1, fixed base 2, and mounting slot 6 cooperate with each other, allowing the pumping housing mechanism 1 to be directly installed in the water box. Then, when sewage needs to be pumped out, the drive motor 3 operates, which drives the drive opening and closing mechanism 4 to rotate, opening the drainage mechanism 5. This allows sewage to be discharged through the pumping housing mechanism 1 and the drainage mechanism 5. This setup can replace commonly used diaphragm pumps or peristaltic pumps, and can be directly placed in water. Furthermore, the use is not affected after the sludge in the sewage dries. The mounting base 7 and connecting pipe 8 can fix the drive motor 3, drainage mechanism 5, and drive opening and closing mechanism 4 in place. Subsequently, the sewage to be pumped out and discharged can be placed into the inlet trough 9 and discharged through the drainage mechanism 5. The inclined bottom of the inner wall of the inlet trough 9 facilitates the entry of sewage into the drainage mechanism 5. The limiting groove 10 on the inner wall of the connecting pipe 8 facilitates the fixed installation of the drainage mechanism 5. The drainage pipe 11 is fixedly installed at the bottom of the connecting pipe 8. Then, the limiting block 13 that cooperates with the limiting groove 10 is fixedly connected to the outer wall of the first connecting seat 12 to fix the position of the first connecting seat 12. After the drive opening and closing mechanism 4 is misaligned with the drainage trough 14, the sewage can be discharged through the inlet trough 9, the drainage trough 14 and the drainage pipe 11. When drainage is required, the drive motor 3 drives the connecting block 15, the second connecting seat 16 and the sealing block 17 to rotate, so that the figure-eight sealing block 17 is misaligned with the drainage trough 14, so that the sewage can be discharged quickly. When the drainage trough 14 needs to be sealed, the drive motor 3 drives the sealing block 17 to correspond with the drainage trough 14, so that it can cooperate with the rubber gasket to complete the sealing of the drainage trough 14.
