[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. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0023] A pressurization assembly for a booster pump, as Figures 1-4 shown, the pressurization assembly is located at the end of the booster pump 1. An impeller groove 10 is provided at the end of the booster pump 1. An impeller is rotatably installed in the impeller groove 10. The impeller is not shown in the figure. A motor is fixedly installed in the booster pump 1. The output end of the motor is fixedly connected to the impeller. An outlet is provided on the impeller groove 10. The water flow discharges from the outlet, which is not shown in the figure.

[0024] The pressurization assembly includes a connector 2. The connector 2 includes a water inlet pipe 22 and a water return pipe 21. The water return pipe 21 is located inside the water inlet pipe 22, and both the water return pipe 21 and the water inlet pipe 22 are fixedly connected to the impeller groove 10 of the booster pump 1. When the impeller of the booster pump 1 works, it will draw water from the water inlet pipe 22. After the water flows through the impeller groove 10, it is discharged from the water outlet. Part of the liquid will flow back through the water return pipe 21 for pressurization.

[0025] One end of the connector 2 away from the booster pump 1 is fixedly connected with an outer pipe 3. An inner pipe 4 is fixedly arranged inside the outer pipe 3. The outer pipe 3 is sleeved outside the inner pipe 4, and the outer pipe 3 is fixedly connected to the water return pipe 21, and the inner pipe 4 is fixedly connected to the water inlet pipe 22.

[0026] One end of the inner pipe 4 away from the water inlet pipe 22 is fixedly connected with a water distribution pipe 5. A water suction pipe 6 is fixedly installed inside the outer pipe 3. A sealing plug 62 is fixedly installed on the outer side of the water suction pipe 6. The sealing plug 62 abuts against the inner wall of the outer pipe 3 to play a sealing role. The water distribution pipe 5 is threadedly connected to one end of the water suction pipe 6. The other end of the water suction pipe 6 is fixedly provided with a water filter cover 61. The water filter cover 61 filters the inhaled water to remove sundries therein.

[0027] A water guiding hole 51 is arranged inside the water distribution pipe 5. A pressurizing member 53 is fixedly arranged inside the water guiding hole 51. A conical groove 55 is formed inside the pressurizing member 53. A conical pipe 54 is fixedly arranged on the water distribution pipe 5. The conical pipe 54 is located above the pressurizing member 53. Water flows upward from the water distribution pipe 5 and sequentially passes through the conical groove 55, the conical pipe 54 and the inner pipe 4.

[0028] When the water flows through the conical groove 55, the flow rate of the water will be accelerated to form a pressurizing effect. The water distribution pipe 5 is provided with confluence grooves 52 on both sides. The confluence grooves 52 are communicated with the water guiding hole 51 and are used to introduce the water flowing back inside the outer pipe 3 into the water guiding hole 51 to provide pressure for the upward supply inside the water guiding hole 51. The water flowing back inside the outer pipe 3 is driven by the impeller and flows downward from the outer pipe 3. During the flowing-back process, the gravitational potential energy is converted into pressure. After the water freely falls, it is pressed into the water guiding hole 51 from the confluence groove 52 to pressurize the water absorption process.

[0029] The working principle is as follows:

[0030] During the water absorption process of the booster pump 1, due to the presence of a large amount of air in the water flow, too large a water absorption lift, etc., the water absorption process pressure of the booster pump 1 may be small, and the water absorption volume and efficiency are low.

[0031] When a pressurization assembly composed of a sleeve structure is connected to the water absorption end of the booster pump 1, water flows into the water filter cover 61 from the end of the outer pipe 3. After being pressurized by passing through the conical groove 55 upward inside the water suction pipe 6, it passes through the water distribution pipe 5 and then enters the booster pump 1 from the inner pipe 4. The water absorption process has a certain pressurization effect.

[0032] Most of the water flow after water absorption is discharged from the water outlet, and a small part of it flows back to the outer pipe 3 through the return pipe 21, descends along the outer pipe 3 to the sealing plug 62, and then the water flow passes through the confluence groove 52 and is pressed into the water guide hole 51 to supplement the water absorption volume, strengthen the water absorption pressure, improve the water absorption strength and speed, and ensure the water absorption pressure of the booster pump 1.

[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.
