Description

Technical Field

[0001] This utility model belongs to the field of water pumps, and in particular relates to a water pump impeller device. Background Technology

[0002] Water pumps are widely used in numerous industrial and civil fields, and the impeller, as one of the core components of a water pump, directly affects the pump's working efficiency and operational stability through its structural design and performance. Traditional water pump impellers typically employ a one-piece structure. While this structure can meet basic usage requirements to a certain extent, it also has limitations. When machining impellers with twisted blades, demolding becomes difficult, or the demolding process is complex and costly. For example, Chinese invention patent application CN105179304A discloses a molding die for a plastic corrosion-resistant and wear-resistant pump and its impeller. Although the molding die can produce blades with different curvatures, the impeller flow channel slider is divided into three groups, which must be removed sequentially. This results in a complex demolding process, increased production costs, and difficulty in designing an automatic demolding mechanism, failing to meet economic production requirements. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a water pump impeller device, including an impeller body and an impeller seat. The impeller body includes an upper circular plate, a lower circular plate, and multiple first blades. The multiple first blades are arranged in a circumferential array and located between the upper and lower circular plates. The lower circular plate has a through mounting hole. The impeller seat includes a base and multiple second blades arranged in a circumferential array on the base. The base is connected to the mounting hole. The multiple second blades correspond one-to-one with the multiple first blades. The corresponding first blades and second blades are spliced ​​together to form the impeller blades.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] like Figures 1 to 8 As shown, this utility model provides a water pump impeller device, including an impeller body 100 and an impeller seat 200. The impeller body 100 includes an upper circular plate 110, a lower circular plate 120, and multiple first blades 130. The multiple first blades 130 are arranged in a circumferential array and perpendicularly between the upper circular plate 110 and the lower circular plate 120, that is, the first blades 130 are perpendicular to both the upper circular plate 110 and the lower circular plate 120. The lower circular plate 120 has a through mounting hole 121, the inner diameter of which is adapted to the outer diameter of the base 210. The impeller seat 200 includes a base 210 and multiple second blades 220 arranged in a circumferential array on the base 210. The base 210 is connected to the mounting hole 121. The multiple second blades 220 correspond one-to-one with the multiple first blades 130, and the corresponding first blades 130 and second blades 220 are spliced ​​together to form the impeller blades.

[0030] Understandably, multiple first blades 130 and multiple second blades 220 correspond one-to-one and are spliced ​​together to form impeller blades. This spliced ​​blade structure has unique advantages. On the one hand, based on the principles of fluid dynamics, a more reasonable blade shape and torsion angle can be designed, enabling the impeller to better adapt to the flow characteristics of the fluid during operation, improving fluid transport efficiency and reducing energy loss. On the other hand, the impeller device is divided into two parts for injection molding, and the two parts can be spliced ​​together after separate injection molding. The mold only needs two flow channel sliders to complete the blade injection molding, which simplifies the mold structure, improves mold forming efficiency, and reduces processing costs.

[0031] like Figures 1 to 4 and Figure 7 As shown, in one embodiment of this utility model, the upper circular plate 110 and the lower circular plate 120 are arranged parallel to each other, and the first blade 130 is perpendicular to the upper circular plate 110 and the lower circular plate 120. The curvatures of the first blade 130 and the second blade 220 are different. The first blade 130 can be a single circular arc blade, and the second blade 220 can be a three-dimensional twisted blade. The first blade 130 and the second blade 220 smoothly transition at the joint, that is, the second blade 220 extends the curvature of the first blade 130 and has a certain twist angle. By setting the above structure, the impeller blade formed by the joint of the first blade 130 and the second blade 220 can have a double curvature, thereby improving the operating efficiency of the impeller.

[0032] like Figure 4 and Figure 5 As shown, in one embodiment of this utility model, the first blade 130 has a downwardly protruding first hot-melt column 131, and the base 210 has a first mating hole 211 corresponding to the position of the first hot-melt column 131. The first hot-melt column 131 is inserted into the first mating hole 211. The second blade 220 has an upwardly protruding second hot-melt column 221, and the upper circular plate 110 has a second mating hole 111 corresponding to the position of the second hot-melt column 221. The second hot-melt column 221 is inserted into the second mating hole 111. The first blade 130 and the second blade 220 are positioned relative to each other by the hot-melt column structure and are hot-riveted together at their respective hot-melt column positions. This eliminates the need for fastener assembly, improves assembly efficiency, and enhances the reliability of the connection between the impeller body 100 and the impeller seat 200. Both the first hot-melt column 131 and the second hot-melt column 221 can be configured with six columns.

[0033] like Figure 4 and Figure 5As shown, in one embodiment of this utility model, the first blade 130 has a groove 132 at one end near the second blade 220, the groove 132 extending vertically. The second blade 220 has a third hot-melt post 222 at one end near the first blade 130, the third hot-melt post 222 extending vertically and placed within the groove 132. The upper circular plate 110 has a third mating hole 114 corresponding to the position of the third hot-melt post 222, and the third hot-melt post 222 is inserted into the third mating hole 114. Through the insertion and engagement of the third hot-melt post 222 and the third mating hole 114, the relative positions of the impeller body 100 and the impeller seat 200 can be quickly positioned, which is beneficial for quickly and accurately connecting the first blade 130 and the second blade 220. It can be understood that the impeller body 100 and the impeller seat 200 can be hot-riveted together through the third hot-melt post 222, further enhancing the connection reliability between the impeller body 100 and the impeller seat 200. The shape of the groove 132 includes, but is not limited to, an arc-shaped groove, a square groove, a dovetail-shaped groove, or an Ω-shaped groove, and the third hot-melt pillar 222 can be configured with 6 pillars. In addition, in other embodiments, the docking between the first blade 130 and the second blade 220 can also be achieved through Ω-shaped pillar docking.

[0034] like Figure 4 As shown, in one embodiment of the present invention, a groove 112 is provided on the bottom surface of the upper circular piece 110. The groove 112 continues the curvature of the first blade 130. The second blade 220 is placed in the groove 112 to facilitate the positioning of the second blade 220.

[0035] like Figure 3 and Figure 7 As shown, in one embodiment of this utility model, a boss 113 protrudes upward from the top surface of the upper circular plate 110, and a mounting groove 115 is provided inside the boss 113 for placing the impeller swivel. The impeller swivel facilitates the positioning of the impeller device when it is installed inside the water pump.

[0036] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, the bottom surface of the base 210 is provided with an annular mounting wall 230 protruding downwards. The inner wall of the mounting wall 230 is provided with a plurality of teeth 231 in the vertical direction. The teeth 231 are used to cooperate with the inner magnet. The inner magnet structure can drive the impeller device to rotate by cooperating with the teeth 231.

[0037] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, the mounting wall 230 has a plurality of circular holes 232 extending radially through it, and the circular holes 232 are used to insert a plug body to connect with the magnetic drive part of the water pump.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
