Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a detachable modular water pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a power source or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] Most existing water pumps have an integrated structure, with the power unit and pump head fixedly connected. When a single component fails, the entire pump must be disassembled and repaired, which is cumbersome and costly. Some detachable water pumps use rigid connection structures such as bolts, requiring tools for disassembly and assembly, which is inefficient and the connection stability is easily affected by vibration. At the same time, the support structure of traditional water pumps is mostly a simple bracket, which is difficult to adapt to different installation scenarios. The sealing structure design of the power component and pump head component is unreasonable, which can easily lead to fluid leakage problems, affecting the life and safety of the equipment. In addition, the internal circuit cables of the power component are messy and easily damaged during maintenance, further increasing the difficulty of maintenance. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figures 1 to 8The diagram illustrates an embodiment of this utility model, relating to a detachable modular water pump, comprising a pump body 10. The pump body 10 includes a power component 20, a pump head assembly 30, a snap-fit ​​structure 40, and an annular support frame 50. The power component 20 and the pump head assembly 30 are detachably connected via the snap-fit ​​structure 40. The snap-fit ​​structure 40 includes a snap-fit ​​protrusion 41, an adapter slot 42, an anti-loosening point 43, and an anti-loosening groove 44. The snap-fit ​​protrusion 41 is disposed on the power component 20. The adapter slot 42 is correspondingly disposed on the pump head assembly 30 and is adapted to engage with the snap-fit ​​protrusion 41. The anti-loosening point 43 is disposed on one side of the snap-fit ​​protrusion 41. The anti-loosening groove 44 is disposed on one side of the adapter slot 42. The annular support frame 50 is used to encircle the power component 20. Specifically, the snap-fit ​​structure 40 enables a detachable connection between the power component 20 and the pump head assembly 30, allowing for quick assembly and disassembly without tools, significantly improving the ease of pump maintenance. After the snap-fit ​​protrusion 41 engages with the adapter slot 42, the anti-loosening point 43 is embedded in the anti-loosening slot 44, forming a secondary lock, effectively preventing the snap-fit ​​from loosening due to vibration during pump operation and ensuring connection reliability. The modular design means that when a single component is damaged, only the corresponding part needs to be replaced, reducing maintenance costs. At the same time, it is easy to replace different specifications of the power component 20 or pump head assembly 30 according to usage requirements, enhancing the equipment's versatility.

[0039] like Figure 2 and Figure 3 As shown, the snap-fit ​​protrusion 41 is an L-shaped protrusion, and the adapter slot 42 is an L-shaped slot that adapts to the L-shaped protrusion. Specifically, the L-shaped snap-fit ​​protrusion 41 and the L-shaped adapter slot 42, through an axial insertion and circumferential rotation adaptation design, can not only achieve axial engagement and fixation, but also prevent the component from axially falling off due to vibration during operation through the lateral limiting of the L-shaped structure, thereby improving the stability and reliability of the connection; in addition, the L-shaped structure has a guiding function during assembly, which facilitates quick alignment and engagement, improving assembly efficiency.

[0040] like Figure 4 and Figure 5As shown, the power assembly 20 includes a motor housing 60, a drive motor 22, and a control circuit board 23. The motor housing 60 has a motor mounting cavity 61 inside, through which the drive motor 22 is fixed. The control circuit board 23 is connected to the rear of the drive motor 22 and is embedded in the motor mounting cavity 61. Specifically, the motor mounting cavity 61 provides precise positioning and fixation for the drive motor 22, ensuring its coaxiality during operation and reducing wear caused by shaking. The control circuit board 23 is embedded in the motor mounting cavity 61 and close to the drive motor 22, shortening the signal transmission path, reducing interference, and improving control accuracy. The integrated structural design makes the power assembly 20 compact, saving space and facilitating docking with other modules such as the pump head assembly 30.

[0041] like Figure 4 As shown, the front end of the motor mounting cavity 61 is connected to an annular mounting base 62, and mounting holes 63 are distributed circumferentially on the outer side of the annular mounting base 62; a plurality of positioning holes 64 are correspondingly provided on the outer side of the motor mounting cavity 61, and the positioning holes 64 and the mounting holes 63 are engaged by bolts (not shown in the figure). Specifically, the mounting holes 63 of the annular mounting base 62 and the positioning holes 64 of the motor mounting cavity 61 are engaged by bolts (not shown in the figure) to achieve precise alignment and rigid connection between the two, ensuring the stability of the power transmission process of the drive motor 22; the detachable bolt connection (not shown in the figure) facilitates the later inspection and replacement of the drive motor 22 inside the motor mounting cavity 61, improving maintenance convenience.

[0042] like Figure 4 As shown, the control circuit board 23 extends with a wiring lug 24, and the motor mounting cavity 61 has a through groove 65 adapted to the wiring lug 24. The through groove 65 connects to a wire hole 25 in the motor housing 60, and the wire hole 25 is used for the circuit cable to pass through and achieve neat routing. Specifically, the wiring lug directly enables the wires to be soldered and fixed. At the same time, the matching design of the wiring lug 24 and the through groove 65 ensures the accurate installation of the control circuit board 23 in the motor mounting cavity 61, avoiding poor circuit contact caused by positional misalignment. The connection structure between the groove 65 and the wire hole 25 allows the circuit cable to be routed neatly, avoiding cable tangling or damage by component compression. It also facilitates quick identification of cable functions during maintenance, improving maintenance efficiency.

[0043] like Figure 6 and Figure 7As shown, the pump head assembly 30 includes a pump head body 70, a connecting shaft 31, an impeller 32, a bushing 33, and a sealing unit 80. The pump head body 70 is a volute cavity 73 with an inlet 71 and an outlet 72, and the volute cavity 73 is connected to the sealing unit 80. One end of the connecting shaft 31 is embedded in the sealing unit 80, and the other end extends into the volute cavity 73. The impeller 32 is drivenly connected to the bushing 33, and the impeller 32 is located inside the volute cavity 73. The bushing 33 is connected to the connecting shaft 31 through a bearing 34, and is used to drive the impeller 32 to rotate around the connecting shaft 31 under the drive of the drive motor 22. The other end of the sealing unit 80 is connected to the drive motor 22, and is used to isolate the pump head body 70 from the drive motor 22. Specifically, the connecting shaft 31 is fixed to the sealing unit 80, providing a stable rotation center for the bushing 33 and the impeller 32, reducing radial runout during rotation, and improving the smoothness of the impeller 32's operation; the bushing 33 is connected to the connecting shaft 31 through the bearing 34, reducing the coefficient of rotational friction, reducing energy loss, and extending the service life of the components; the sealing unit 80 effectively isolates the pump head body 70 from the drive motor 22, preventing fluid leakage into the motor and causing damage, thus improving safety.

[0044] like Figure 6 As shown, the inlet 71 is a transverse pipe joint, aligned with the axial direction of the volute cavity 73; the outlet 72 is a longitudinal pipe joint, aligned with the radial direction of the volute cavity 73. Specifically, the transverse alignment of the inlet 71 with the axial direction of the volute cavity 73 facilitates the axial entry of fluid into the center of the impeller 32, reducing inlet resistance; the longitudinal alignment of the outlet 72 with the radial direction of the volute cavity 73 allows the fluid ejected by the impeller 32 to efficiently convert kinetic energy into pressure energy within the volute, improving the pump's head and flow performance; the rational design of the inlet 71 and outlet 72 also facilitates connection with external pipelines, optimizing pipeline layout.

[0045] like Figure 6 As shown, the sealing unit 80 includes a sealing cavity 81 and a sealing surface 82. The sealing cavity 81 is used to accommodate the connecting shaft 31 and the bushing 33. The sealing surface 82 is located on one side of the sealing cavity 81. Specifically, the sealing cavity 81 accommodates the connecting shaft 31 and the bushing 33, providing them with a protective space to prevent external impurities from entering and affecting the rotational accuracy. The sealing surface 82 ensures a tight fit between the sealing unit 80 and the pump head body 70 and the drive motor 22, providing an installation base for subsequent sealing structures such as sealing rings, enhancing the overall sealing reliability, and further preventing fluid leakage.

[0046] like Figure 6As shown, an annular sealing groove 83 is formed on the side of the sealing surface 82 opposite to the sealing cavity 81. A circular sealing ring 84 is installed in the annular sealing groove 83, and the outer diameter of the circular sealing ring 84 is interference-fitted with the groove width of the sealing groove. Specifically, the elastic deformation of the circular sealing ring 84 fills the sealing gap, ensuring absolute sealing of the sealing surface 82 and effectively preventing fluid leakage in the pump head. The material properties of the circular sealing ring 84 enable it to adapt to different temperature and pressure conditions, maintaining good sealing performance even after long-term use, thus improving the working stability of the water pump.

[0047] like Figure 8 As shown, the annular support frame 50 includes an arc-shaped circumferential portion 51 and a bottom support portion 52. The top of the arc-shaped circumferential portion 51 is provided with two elastic claws 53, each with a screw hole 54. Support legs 55 extend outwards from both sides of the bottom support portion 52, and each support leg 55 has an assembly groove 56 at its end. Specifically, the arc-shaped circumferential portion 51 of the annular support frame 50 can tightly fit the power component 20, achieving stable circumferential positioning and reducing vibration during operation. The bottom support legs 55 extend outwards and are provided with assembly grooves 56, adapting to different installation foundations and enhancing the overall placement stability of the water pump. The elastic claws 53 with screw holes 54 facilitate flexible connection and installation.

[0048] The working principle of this utility model is as follows:

[0049] The power assembly 20 and the pump head assembly 30 are modularly and detachably connected through an L-shaped snap-fit ​​protrusion 41 and an L-shaped adapter slot 42. The snap-fit ​​protrusion 41 is located on one side of the motor housing 60, and the adapter slot 42 is located on the side of the sealing unit 80 away from the sealing surface 82. The annular support frame 50 provides a circumferential support for the power assembly 20 to reduce vibration.

[0050] When the water pump is working, after the drive motor 22 is connected to the power supply, it is started and outputs power through the control circuit board 23, which drives the bushing 33 in the pump head assembly 30 to rotate around the fixed connecting shaft 31. The bushing 33 then drives the impeller 32 to rotate synchronously in the volute cavity 73 of the pump head body 70. When the impeller 32 rotates, a low-pressure zone is formed in its central area. Under the action of pressure difference, the external fluid flows axially into the volute cavity 73 from the transverse inlet 71 and enters the center of the impeller 32. Under the action of centrifugal force of the impeller blades, it is thrown to the edge of the volute cavity 73. After the fluid completes the conversion of kinetic energy into pressure energy in the volute, it is discharged from the longitudinal outlet 72 to achieve transportation.

[0051] The sealing unit 80 achieves isolation and sealing between the pump head and the motor through structures such as the circular sealing ring 84, preventing fluid leakage and ensuring continuous and stable operation of the equipment.

[0052] This utility model enables quick assembly and disassembly of the power component 20 and the pump head component 30 through the snap-fit ​​structure 40. Combined with the stable support of the ring support frame 50, it greatly improves the ease of maintenance and stability of use of the equipment. The integrated design and precise positioning structure of the power component 20 ensures power transmission efficiency and control accuracy. The optimized fluid path of the pump head component 30 and the multiple sealing design of the sealing unit 80 not only improve the infusion efficiency but also effectively prevent leakage and ensure equipment safety. The overall modular layout also enhances the versatility and expandability of the equipment, allowing for flexible replacement of components as needed, reducing usage and maintenance costs.

[0053] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
