[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This embodiment relates to a sewage pump, such as Figure 1-4 As shown, it includes a diaphragm pump 2, a housing 1 mounted on the diaphragm pump 2, and a drive assembly mounted on the housing 1; the diaphragm pump 2 has an inlet 14, an outlet 11, a chamber 12, an outlet 13, and an outlet 15 that are connected in sequence; a diaphragm 21 is movably connected inside the chamber 12; and a hose 20 is installed between the inlet 11, the chamber 12, and the outlet 13. The housing 1 installed on the diaphragm pump 2 has two plugging components inside the housing 1 for alternately blocking the inlet 11 and the outlet 13. A buffer component is provided between the plugging component and the hose 20 to buffer the impact force of the plugging component on the hose 20. A drive assembly is mounted on the housing 1, and the drive assembly is connected to the diaphragm 21 and the two sealing components. In this system, when the drive assembly draws wastewater into the hose 20 through the inlet 14 and outlet 11 via the diaphragm 21, it drives one of the sealing elements to move away from the hose 20, opening the inlet 11. Simultaneously, it drives the other sealing element to impact the buffer element, pressing the hose 20 shut and closing the outlet 13. When the drive assembly discharges wastewater through the outlet 13 and outlet 15 via the diaphragm 21, it drives one sealing element to impact the buffer element, pressing the hose 20 shut and closing the inlet 11. Simultaneously, it drives the other sealing element to loosen the hose 20, opening the outlet 13. By using the buffer element, the impact force of the sealing elements on the hose 20 can be reduced, extending the service life of the hose 20 and reducing the noise generated by the sealing elements impacting the hose 20. Furthermore, when the drive assembly is working, the diaphragm 21 and the two sealing elements move synchronously and in coordination, further reducing noise generation.

[0022] Specifically, such as Figure 2-4 As shown, the drive assembly includes a power component, a transmission component, and a gear assembly. The power component is fixed to the housing 1, the transmission component is fixedly connected to the power component, and one side of the transmission component is fixedly connected to one of the sealing components, while the other side is connected to another sealing component via the gear assembly. The transmission component is fixedly connected to the diaphragm 21.

[0023] The power component includes a motor 3, the housing 1 is connected to the motor 3 by bolts, and the transmission component is fixedly connected to the output end of the motor 3.

[0024] The transmission component includes an eccentric structure and a connecting plate 6. One end of the eccentric structure is fixedly connected to the output end of the motor 3, and the other end is set on the connecting plate 6. The connecting plate 6 is slidably connected to the inside of the housing 1, and one side of the connecting plate 6 is fixedly connected to one of the sealing components, while the other side is connected to another sealing component through a gear assembly.

[0025] The eccentric structure includes an eccentric wheel 5, a double arc groove 17, and a protruding rod 18. The eccentric wheel 5 is fixedly connected to the output end of the motor 3. The protruding rod 18 is fixed at the top edge of the eccentric wheel 5. The double arc groove 17 is located inside the connecting plate 6. The protruding rod 18 moves eccentrically around the double arc groove 17.

[0026] The gear assembly includes a first gear rack 7, a gear 8, and a second gear rack 9. The first gear rack 7 is fixed to the side of the connecting plate 6, the second gear rack 9 is fixed to a nearby sealing member, and the gear 8 meshes between the first gear rack 7 and the second gear rack 9.

[0027] The sealing component includes a movable rod 10 and a spring 19. Both movable rods 10 are slidably connected to the inside of the housing 1. One movable rod 10 is fixedly connected to the connecting plate 6, and the other movable rod 10 is fixedly connected to the second gear rack 9. The spring 19 is installed on the movable rod 10. The two movable rods 10 are used to squeeze the hose 20 to seal the inlet 11 or the outlet 13.

[0028] like Figure 4 As shown, the buffer includes a rubber head 4 and a rubber sleeve 22. The rubber head 4 is fixed to the hose 20, and the rubber sleeve 22 is fixed to the end of the movable rod 10. The rubber sleeve 22 is sleeved on the rubber head 4. The collision between the rubber head 4 and the rubber sleeve 22 is an elastic collision, which can effectively buffer the impact force on the hose 20.

[0029] Furthermore, when the rubber head 4 and the rubber sleeve 22 move relative to each other, the arc-shaped rubber head 4 and the rubber sleeve 22 can reduce friction and further reduce noise generation.

[0030] The top of the housing 1 has a detachable connection (such as bolt connection, snap connection, etc.) with a top cover 16, which facilitates the installation of the structure inside the housing 1.

[0031] The working principle of this utility model is roughly as follows: When the sewage pump is working, the motor 3 drives the eccentric wheel 5 to drive the convex rod 18 to make eccentric movements in the double arc groove 17 inside the connecting plate 6, causing the connecting plate 6 to reciprocate within the housing 1. The connecting plate 6 will drive the diaphragm 21 to repeatedly squeeze the hose 20 inside the chamber 12, so that the sewage pump can achieve negative pressure pumping. At the same time, the connecting plate 6 drives the sealing component fixedly connected to it to move together. The other sealing component drives the first gear rack 7 to move through the connecting plate 6. The first gear rack 7 drives the gear 8, and then drives the second gear rack 9 to achieve synchronous movement.

[0032] When the drive assembly drives the diaphragm 21 to draw sewage into the hose 20 through the inlet 14 and inlet 11, the motor 3 drives the connecting plate 6 to drive the gear assembly to move (the specific operation will not be described in detail). The gear assembly drives the sealing member connected to it away from the hose 20 to open the inlet 11. At the same time, the connecting plate 6 directly drives another sealing member to hit the buffer member and press the hose 20 to close the outlet 13, thus completing the sewage pump water intake operation. When the drive assembly drives the diaphragm 21 to discharge sewage through the outlet 13 and the nozzle 15, the motor 3 drives the connecting plate 6 to drive the gear assembly to move (the specific operation will not be described in detail). The gear assembly drives the sealing component connected to it to impact the buffer component and press the hose 20 to close the inlet 11. At the same time, the connecting plate 6 directly drives another sealing component to loosen the hose 20 and open the outlet 13, thus completing the sewage pump drainage operation.

[0033] When the sealing component impacts the buffer component and compresses the hose 20, the moving rod 10 moves linearly via the gear assembly or connecting plate 6. The moving rod 10 causes the rubber sleeve 22 to impact the rubber head 4. Then, the rubber sleeve 22 is placed on the rubber head 4, opening the inlet 11 or outlet 13. Since both the rubber sleeve 22 and the rubber head 4 are made of rubber and are arc-shaped, they can effectively buffer the impact force on the hose 20. During this process, the rubber sleeve 22 compresses the spring 19 on the moving rod 10, causing the spring 19 to deform elastically. The spring 19 can also buffer the impact force, preventing the sealing component from directly colliding rigidly with the hose 20. This can greatly reduce the noise generated when the sewage pump is working and extend the service life of the hose 20. Furthermore, when the drive assembly is working, the diaphragm 21 and the two sealing components move synchronously and in coordination, which can reduce the generation of noise. When there is a foreign object in the inlet 11 or outlet 13, the spring 19 will be compressed, and the movable rod 10 will move back under the elastic force of the spring 19 to prevent the movable rod 10 from being stuck due to the presence of the foreign object.

[0034] When the sealing component moves away from the hose 20, the movable rod 10 moves linearly through the gear assembly or connecting plate 6. The movable rod 10 pulls the rubber sleeve 22 to separate from the rubber head 4, so that the inlet 11 or outlet 13 is opened.

[0035] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
