Description

Technical Field

[0001] This utility model relates to the field of pump device technology, and in particular to a wave-making pump motor rotor assembly and a wave-making pump. Background Technology

[0002] The wavemaker pump motor rotor is one of the core components of a wavemaker pump. In existing designs, the rotor body is typically enclosed within a motor housing, while the rotor shaft extends through the housing to the outside, connecting to impellers and other agitator components used to drive the water flow. During operation, the motor converts electrical energy into mechanical energy to drive the rotor's rotation. This power is then transmitted through the rotor shaft, causing the agitator components to rotate and creating waves. However, because the rotor body is enclosed within the motor housing, its heat dissipation relies primarily on the contact between the extended rotor shaft and the water flow. This heat dissipation method has limited effectiveness, and the rotor's heat dissipation efficiency directly impacts the motor's performance. Therefore, to improve heat dissipation efficiency and motor performance, it is necessary to optimize and improve the existing wavemaker pump motor rotor structure. Utility Model Content

[0033] Reference Figures 1 to 5 A wave-generating pump motor rotor assembly includes a rotor body 100 and a rotor shaft 200. The rotor body 100 has a first through hole 101. The rotor shaft 200 passes through the first through hole 101 and is connected and fixed to the rotor body 100. The rotor shaft 200 has power output parts 210 at both ends along the axial direction for extending out of the motor housing to transmit power. The rotor shaft 200 has a second through hole 201. The second through hole 201 passes through the power output parts 210 at both ends of the rotor shaft 200 along the axial direction of the rotor shaft 200 to allow external water flow to pass through.

[0034] Understandably, such as Figure 2 , Figure 4 and Figure 5As shown, the axis of the rotor shaft 200 is parallel to the vertical direction. The first through hole 101 extends vertically, through which the rotor shaft 200 passes and is fixedly connected to the rotor body 100. The second through hole 201 extends vertically through the power output parts 210 at both ends of the rotor shaft 200. In use, the power output parts 210 at both ends of the rotor shaft 200 extend outside the motor housing and are connected to the stirring component. The rotor assembly rotates and transmits power outward through the power output parts 210, driving the stirring component to rotate and thus creating waves. Because the second through hole 201 extends through the power output parts 210 at both ends of the rotor shaft 200, external water flows through the second through hole 201 into the interior of the rotor shaft 200 during use. This water flow can carry away some of the heat from the rotor assembly, improving heat dissipation efficiency and thus enhancing motor performance.

[0035] In practical applications, the specific structure of the rotor body 100 and the rotor shaft 200 can be set according to the actual needs of use. It will not be described in detail here, but will be explained in detail below.

[0036] In some embodiments, the wall of the second through hole 201 is provided with a protrusion 220. It is understood that, as Figures 1 to 5 As shown, by providing a protrusion 220 on the wall of the second through hole 201, the contact area between the inside of the second through hole 201 and the water flow can be increased, thereby increasing the heat exchange area and improving heat dissipation efficiency, making it easier to use. In practical applications, in addition to the above structure, the wall of the second through hole 201 can also be provided with a recess, or both a protrusion 220 and a recess can be provided simultaneously, depending on the actual needs of use.

[0037] In some embodiments, the protrusion 220 is provided with a plurality of protrusions that are spaced apart on the wall of the second through hole 201. The protrusion 220 has an elongated structure and is spirally arranged around the axis of the rotor shaft 200.

[0038] Understandably, such as Figure 3 , Figure 4 and Figure 5 As shown, multiple protrusions 220 are provided, and these protrusions 220 are evenly spaced around the axis of the rotor shaft 200. The protrusions 220 have an elongated structure and are spirally arranged around the axis of the rotor shaft 200. This design, on the one hand, significantly increases the contact area between the second through hole 201 and the water flow, thus increasing the heat exchange area; on the other hand, the spirally arranged protrusions 220 drive the water flow, which is beneficial for creating turbulence and achieving a better heat exchange effect. In practical applications, the specific shape of the protrusions 220 can be set according to actual usage requirements.

[0039] In some embodiments, a silicone damping pad 310 is provided at the end face of the rotor body 100. The silicone damping pad 310 is annular, and the rotor shaft 200 passes through the silicone damping pad 310.

[0040] Understandably, such as Figures 1 to 5 As shown, two silicone vibration damping pads 310 are provided, located at the upper and lower end faces of the rotor body 100 respectively. The silicone vibration damping pads 310 are annular, and the rotor shaft 200 passes through the silicone vibration damping pads 310. In use, the silicone vibration damping pads 310 can abut against other components of the motor to achieve a certain buffering and vibration reduction effect, which helps to reduce operating noise and facilitates use. In actual applications, the silicone vibration damping pads 310 can be set according to actual usage needs.

[0041] In some embodiments, the silicone damping pad 310 is provided with positioning feet 311 on its periphery, and the rotor body 100 is provided with a positioning groove 102 at its end face that is inserted and engaged with the positioning feet 311.

[0042] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, each silicone damping pad 310 is provided with three positioning feet 311, which are evenly spaced along the outer periphery of the silicone damping pad 310. The upper and lower end faces of the rotor body 100 are each provided with three corresponding positioning grooves 102. During assembly, the silicone damping pad 310 is assembled by inserting the positioning feet 311 into the positioning grooves 102. Its structure is simple and easy to install and use. In practical applications, the specific structure of the positioning feet 311 and positioning grooves 102 can be set according to actual usage requirements.

[0043] In some embodiments, a recessed position 103 is provided at the end face of the rotor body 100, and a silicone damping pad 310 is disposed in the recessed position 103. The wall of the recessed position 103 is provided with a protruding limiting part 110, and the limiting part 110 abuts against the peripheral side wall of the silicone damping pad 310.

[0044] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, recesses 103 are provided at both the upper and lower end faces of the rotor body 100. The wall of each recess 103 has a radially extending protruding limiting portion 110. Three limiting portions 110 are evenly spaced around the axis of the rotor shaft 200. Silicone shock-absorbing pads 310 are disposed in the recesses 103 and positioned by abutting against the limiting portions 110. This design is simple, facilitates the positioning and fixing of the silicone shock-absorbing pads 310, and increases the area of ​​the upper and lower ends of the rotor body 100, which is beneficial for heat dissipation at the ends and convenient for use. In practical applications, the specific structures of the recesses 103 and the limiting portions 110 can be set according to actual usage requirements.

[0045] In some embodiments, the outer peripheral wall of the silicone damping pad 310 is in contact with the groove wall of the positioning groove 102 or with the limiting part 110 via an inclined surface. It is understood that installing the silicone damping pad 310 via an inclined surface contact facilitates its insertion into the corresponding positioning groove 102 and recess 103, and also allows the inclined surface reaction force to ensure better contact between the silicone damping pad 310 and the external component, thus facilitating its use.

[0046] In some embodiments, a wear-resistant plate 320 is provided at the end face of the rotor body 100. The wear-resistant plate 320 is annular, and the rotor shaft 200 passes through the wear-resistant plate 320.

In use, the wear-resistant plates 320 can abut against other components of the motor to increase the wear resistance of the end faces of the rotor body 100, which is beneficial to extending the service life of the rotor assembly. In practical applications, the wear-resistant plates 320 can be made of ceramic material, and the number of wear-resistant plates 320 can be adjusted according to actual usage requirements.

[0048] In some embodiments, the inner side of the silicone damping pad 310 is recessed and defines an annular mounting groove 301 between it and the outer peripheral side of the rotor shaft 200, and the wear-resistant plate 320 is disposed in the mounting groove 301.

[0049] Understandably, such as Figures 1 to 5 As shown, the inner side of the silicone damping pad 310 is recessed to define an annular mounting groove 301 between it and the outer periphery of the rotor shaft 200. The mounting groove 301 is adapted to the wear-resistant plate 320, which is disposed in the mounting groove 301 to facilitate its installation and use. In practical applications, the specific installation method of the wear-resistant plate 320 can be varied according to the actual use.

[0050] In some embodiments, the outer peripheral wall of the rotor shaft 200 is provided with a cutout 202, and the wall of the first through hole 101 is provided with a rotation limiting part 120.
