The pressurization effect of this booster pump structure on the water flow is not obvious, and the water inlet lift is small. Therefore, it is necessary to design a multi-loop pressurization structure for a booster pump. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0023] A multi-loop pressurization structure of a booster pump, as Figures 1 - 4 shown. The multi-loop pressurization structure includes a connection part 2 and a pipeline assembly 3. The pipeline assembly 3 is connected to the booster pump 1 to supply water when the booster pump works. An absorption chamber 11 is provided at the end of the booster pump 1. An impeller is rotatably arranged in the absorption chamber 11, and the impeller is not shown in the figure. An outlet 13 is fixedly provided on the absorption chamber 11. An inlet 12 and a return port 14 are provided on one side of the absorption chamber 11. The return port 14 is located on one side of the inlet 12.

[0024] The impeller is fixedly connected to the output end of the motor in the booster pump 1. After the motor is powered on and started, the output end of the motor drives the impeller to rotate and work, sucking the water in the inlet 12 into the absorption chamber 11. When the impeller rotates, most of the water flow is discharged from the outlet 13, and a small part of the water flow enters the return port 14 under the drive of the impeller.

[0025] The connection part 2 includes a first connection pipe 21 and a second connection pipe 22. The second connection pipe 22 is located on one side of the first connection pipe 21. A through hole 23 is fixedly provided on one side of the first connection pipe 21. One end of the second connection pipe 22 is fixedly connected to the through hole 23, and the other end is fixedly connected to a second water pipe 32. The second connection pipe 22 is communicated with the first connection pipe 21 through the through hole 23. A first water pipe 31 is fixedly connected to the first connection pipe 21.

[0026] The first water pipe 31 is connected to the inlet 12 for guiding the water flow into the inlet 12. The second water pipe 32 is communicated with the return port 14. A water guiding member 4 is fixedly installed in the first connection pipe 21. One end of the water guiding member 4 is fixedly provided with a conical cover 42, which is threadedly connected to the inner wall of the first connection pipe 21. The connection part of the conical cover 42 and the first connection pipe 21 is located above the through hole 23. A conical hole is provided in the water guiding member 4, and the conical hole is communicated with the conical cover 42.

[0027] A pressurizing member 43 is installed at one end of the water guiding member 4. A conical surface 45 is fixedly provided on the pressurizing member 43. The conical surface 45 is located on one side of the through hole 23. The water flowing back from the return port 14 of the booster pump 1 returns to the first connection pipe 21 through the through hole 23, and then enters the conical cover 42 along the conical surface 45, and then flows into the conical hole from the conical cover 42. During the process from the conical cover 42 to the conical hole, the cross-sectional area of the flow path becomes smaller, which will accelerate the water flow and realize the water flow pressurization effect. Moreover, the part of the water flow that flows back will increase the water volume at the water absorption place and reduce the sucked air supply, which will increase the water absorption lift of the booster pump 1.

[0028] A through hole 44 is provided in the pressurizing member 43. A water inlet hole 24 is fixedly provided below the first connection pipe 21. A water filtering member 5 is fixedly connected below the water inlet hole 24. A filter screen 51 is fixedly provided on the water filtering member 5 for filtering the water flow sucked by the booster pump 1 from the water inlet hole 24 to prevent sundries such as waterweeds from entering the booster pump 1.

[0029] The working principle is as follows:

[0030] A pipeline assembly 3 composed of a first water pipe 31 and a second water pipe 32 is fixedly installed on a booster pump 1, and then the first water pipe 31 and the second water pipe 32 are fixedly installed on a connecting part 2.

[0031] During actual use, water flows through a filter screen 51 and then enters a pressurizing part 43. The water is filtered clean by the filter screen 51, and after passing through a through hole 44 of the pressurizing part 43, it enters a conical cover 42. After being pressurized by a water guiding part 4, the water flow accelerates into the first water pipe 31. Due to actual water absorption, the water flow will contain gas, which affects the flow rate and flow volume of the water flow.

[0032] After the water flow passes through the impeller, it flows back through a water return port 14, and then passes through a through hole 23 and enters the space between the pressurizing part 43 and the conical cover 42 to supplement the water absorption. Moreover, the returned water will also be affected by gravity, converting gravitational potential energy into pressure for boosting the water flow, further increasing the water absorption flow rate and supplementing the water flow pressure. The structure is simple, and it automatically increases the inlet pressure and water absorption lift of the water pump.

[0033] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
