A pump body structure

Abstract

This utility model relates to the field of pump body technology, specifically disclosing a pump body structure. The pump body structure includes a main body, which includes: a mounting frame, on one side of which a motor is fixedly mounted, and on the other side of which a housing is fixedly mounted; and an impeller assembly, which includes several fan blades, with a water baffle fixedly mounted on the outside of each fan blade. One side of each fan blade has an array of arc-shaped blades, and the other side has a rotatable cutting element. A protrusion is fixedly mounted on the side of each fan blade, with an arc-shaped surface at the end of the protrusion. In this pump body structure, the impeller assembly is installed inside the pump body. The impeller assembly draws water from the inlet pipe, causing the water to flow over the arc-shaped blades and be transported to the side of the fan blades. The protrusion then drives the liquid to flow to the outlet pipe, pressurizing the liquid and maintaining the outlet pressure. This pressurized water delivery meets the water supply requirements of bathtubs and other similar applications, ensuring water pressure and supplying aerated water to the bathtub. The operation is stable and reliable.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] A pump body structure, such as Figure 1 As shown, the pump body structure includes a main body 1, on which water pipes 3 are fixedly connected, respectively located at the inlet and outlet ends of the pump body structure.

[0032] like Figures 2-9 As shown, the main body 1 includes a mounting frame 11. A motor 12 is fixedly mounted on one side of the mounting frame 11. A support base 13 is fixedly mounted below the housing of the motor 12 for mounting and fixing the motor 12. A housing 14 is fixedly mounted on the other side of the mounting frame 11. A water inlet pipe 15 is fixedly mounted on one end of the housing 14. A water outlet pipe 16 is fixedly mounted on the housing 14.

[0033] Water is supplied to the outer casing 14 through the water outlet pipe 16 and the water inlet pipe 15, and then supplied through the water outlet pipe 16. The water is then transported to the place where water needs to be supplied, such as a bathtub or other water-holding container, via the water pipe 3.

[0034] A shaft 19 is rotatably provided inside the housing 14. The shaft 19 is fixedly connected to the output end of the motor 12. Under the drive of the motor 12, the shaft 19 is rotated.

[0035] An impeller assembly 17 is provided on the outside of the shaft 19. One end of the impeller assembly 17 is provided with a water inlet 18, which faces the water inlet pipe 15. When the impeller assembly 17 rotates, the water supplied by the water inlet pipe 15 is drawn into the impeller assembly 17 through the water inlet 18.

[0036] The end of the shaft 19 is located at the inlet 18, and the impeller assembly 17 is locked onto the shaft 19 by bolts installed at the end of the shaft 19.

[0037] The impeller assembly 17 includes several fan blades 2. A water baffle 5 is provided on the outside of each fan blade 2. The fan blades 2 and the water baffle 5 are fixed together by ultrasonic welding. Multiple water baffles 5 are coaxially mounted and fixed inside the housing 14. A cutting element 4 is rotatably located inside the fan blades 2 and is fixedly connected to a shaft 19. A protrusion 22 is fixedly provided on the side of the fan blades 2, and an arc surface 23 is provided at the end of the protrusion 22.

[0038] One side of the fan blade 2 is fixed with an arc blade 21 arranged in a circular array. The cutting element 4 and the arc blade 21 are located on both sides of the fan blade 2. The water inlet 18 is located at the axis of the cutting element 4 and is used to supply water into the cutting element 4. The water and the gas in the water are cut by the cutting element 4 and then input to the bottom of the protrusion 22. Then, it flows through the arc surface 23 to the other side of the fan blade 2. The water is guided by the arc blade 21 and the water baffle 5 to the next set of cutting elements 4. This continues until the water is delivered to the last set of water baffles 5. The last set of water baffles 5 has an array of opening slots 10 for discharging water from the water baffles 5 and then outputting it to the water outlet pipe 16.

[0039] The cutting component 4 is welded and includes two side plates. One side plate has a water inlet 18. A cutting blade 41 is located between the two side plates to cut the water entering from the water inlet 18 and generate bubbles. For some water supply environments, such as bathtubs, aquaculture, and water treatment, this can increase the oxygen content in the water.
