Description

Technical Field

[0001] This utility model relates to an improvement in the structure of a water pump, specifically a low-resistance water pump. Background Technology

[0002] A water pump is a device that combines a motor and a pump body structure, allowing for integrated setup and operation. The water body of the pump controls the direction of water flow, with inlet and outlet sections separating the flow paths. The pump body provides power, driving the directional movement of the water. Therefore, the water flow within the water body has strong impact pressure. When the water flow resistance is high, it reduces the pump's efficiency and lifespan, thus requiring improvements to the water body structure. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the prior art and to provide a low-resistance water pump water body.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the water pump body includes an outer shell and an inner tube. The inner tube penetrates and intrudes into the outer shell. The outer shell is connected to an inlet, and the inner tube is connected to an outlet. The part of the outer shell connected to the inlet is formed into a smooth transition structure, which smoothly transitions from the large diameter of the outer shell to the small diameter of the inner tube. The outer shell is formed with an outer sleeve opening and is connected to the outer sleeve of the pump body. The part of the inner tube in the outer shell has a smooth surface and is formed with an inner sleeve opening. A smooth body is formed between the outer surface of the inner sleeve opening and the inner surface of the outer shell. The smooth body smoothly connects the low surface of the inlet and the high surface of the outer sleeve opening. The entire surface of the water pump body is smooth, which reduces the friction of the water flow. It has a nested structure of outer shell and inner tube, forming an outer water flow area and an inner water flow area. The pump body structure provides water flow power. The inlet directly faces the structure of the inner tube inside the outer shell. Therefore, a smooth body is set in the cover to divert the water flow to both sides to reduce the direct impact on the inner tube. In addition, the part that flows through is a smooth surface, reducing water flow resistance. The inner and outer sleeves correspond to the inner and outer cylinders of the pump body, forming an isolated environment with pressure difference.

[0005] Furthermore, the bottom of the outer shell is provided with support feet, which are evenly distributed at the four corners. The bottom surfaces of all support feet are on the same horizontal plane, and all support feet are vertically arranged. The bottom of each support foot is formed with an interlocking step or a fixing hole. The support feet are the basic structure that allows the water body to be placed stably. The four-legged support structure has good stability and is vertically arranged, which facilitates connection with the underlying foundation device. The connection can be made by interlocking or by installing fixing screws.

[0006] Furthermore, the interlocking steps are distributed on all the support feet, and the interlocking steps on all the support feet form an edge mating structure of the support surface, which is mated and fixed with the edge of the support platform of the water pump base. If an interlocking structure is adopted, using a mating surface with a stepped form, which is directly nested and mated with the underlying foundation surface, it also has a good stabilizing effect.

[0007] Furthermore, the outer shell is provided with drainage holes, including an inner drainage outlet and an outer drainage outlet. The inner drainage outlet penetrates from the outside of the outer shell and connects to the inside of the inner tube, connecting the space inside the inner tube with the external environment. The outer drainage outlet penetrates the outer shell and connects the inner and outer environments of the outer shell. All drainage holes are located at the low position of the outer shell. These drainage holes are maintenance devices for water bodies. If the water pump malfunctions, the internal water can be quickly drained through the drainage holes, improving maintenance efficiency. The use of drainage holes on both the inner and outer sides ensures high drainage efficiency and facilitates rapid problem diagnosis.

[0008] Furthermore, the height of the inner sleeve opening is lower than the height of the outer sleeve opening, and both the inner and outer sleeve openings have grooves on their edges, into which sealing rings are embedded. The inner and outer sleeve openings are independent flow structures; therefore, a sealing structure is provided to prevent pressure loss and improve the pump's operating efficiency.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement of the water body device of a water pump, which can reduce water flow resistance, improve the working efficiency of the water pump, facilitate the installation of components, facilitate maintenance and repair, and help the water pump to work stably for a long time.
