Description

Technical Field

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

[0002] Water pumps, as important mechanical equipment, are widely used in various fields such as industry, agriculture, household use, and municipal management. Traditional water pumps typically consist of a casing, a pump motor, and a series of connecting components. The casing, as the main structure of the pump, not only provides protection and support but also houses the internal operating components, such as the pump motor. The pump motor is the core component that drives the pump rotor to rotate, converting electrical energy into mechanical energy to achieve the pumping function.

[0003] In existing water pump designs, the casing is usually equipped with an adapter, and the adapter and the water pump motor are connected by a water guide, such as a hose. As a flexible and durable connector, the hose is widely used to connect the water pump motor and the adapter. However, there is a potential risk of leakage at the connection points between the hose and the adapter or the water pump motor. This risk of leakage mainly comes from poor sealing at the connection points between the hose and the adapter or the water pump motor. Since the water pump will generate a certain amount of vibration and displacement during operation, if the seals at both ends of the hose are not designed properly or installed improperly, it is easy to cause the seal to fail, thereby causing leakage.

[0004] Furthermore, the leak occurs inside the casing. Once a leak occurs, it will not only reduce the efficiency of the water pump, but may also damage other components inside the casing, causing electrical short circuits and other safety issues, thus threatening the overall operational stability and safety of the water pump.

[0036] Water pumps, as important mechanical equipment, are widely used in various fields such as industry, agriculture, household use, and municipal management. Traditional water pumps typically consist of a casing, a pump motor, and a series of connecting components. The casing, as the main structure of the pump, not only provides protection and support but also houses the internal operating components, such as the pump motor. The pump motor is the core component that drives the pump rotor to rotate, converting electrical energy into mechanical energy to achieve the pumping function.

[0037] In existing water pump designs, the casing is usually equipped with an adapter, and the adapter and the water pump motor are connected by a water guide, such as a hose. As a flexible and durable connector, the hose is widely used to connect the water pump motor and the adapter. However, there is a potential risk of leakage at the connection points between the hose and the adapter or the water pump motor. This risk of leakage mainly comes from poor sealing at the connection points between the hose and the adapter or the water pump motor. Since the water pump will generate a certain amount of vibration and displacement during operation, if the seals at both ends of the hose are not designed properly or installed improperly, it is easy to cause the seal to fail, thereby causing leakage.

[0038] Furthermore, the leak occurs inside the casing. Once a leak occurs, it will not only reduce the efficiency of the water pump, but may also damage other components inside the casing, causing electrical short circuits and other safety issues, thus threatening the overall operational stability and safety of the water pump.

[0039] This utility model proposes a water pump device 100.

[0040] Please see Figures 1 to 6 In one embodiment of this utility model, the water pump device 100 includes:

[0041] Casing 1;

[0042] Water pump motor 2, the water pump motor 2 is located inside the housing 1;

[0043] The water pump motor 2 is integrally provided with a drain pipe 3. The drain pipe 3 also includes a connecting end on the side away from the water pump motor 2. The connecting end is used to connect to a water guide pipe. The connecting end passes through the housing 1 and is exposed to the outside.

[0044] The technical solution of this utility model adopts the drain pipe 3 that is integrated with the water pump motor 2 to avoid leakage inside the housing 1. The connection end of the drain pipe 3 and the water guide is inserted through the housing 1 and exposed to the outside, which facilitates the connection and fixation of the water guide. There is no connection point between the drain pipe 3 and the water guide inside the housing 1, which avoids leakage inside the housing 1 and thus prevents safety accidents, thereby improving the safety of equipment operation.

[0045] Optionally, the drain pipe 3 includes an inlet pipe 31 and an outlet pipe 32;

[0046] The water inlet pipe 31 is integrally connected to the water inlet end of the water pump motor 2;

[0047] The water outlet pipe 32 is integrally connected to the water outlet end of the water pump motor 2;

[0048] The connection ends of the water inlet pipe 31 and the water outlet pipe 32, which are away from the water pump motor 2, both pass through the housing 1 and are located on the outside of the housing 1.

[0049] It is understandable that by directly and integrally connecting the inlet pipe 31 and the outlet pipe 32 to the inlet and outlet ends of the water pump motor 2, the internal structure of the water pump is greatly simplified, and the use of connectors and hoses is reduced. By eliminating these intermediate links, the inlet pipe 31 and the outlet pipe 32 are directly integrated with the water pump motor 2, and the connection end passes through the housing 1 on the outside, thereby effectively reducing the risk of leakage, reducing manufacturing costs, and improving the overall reliability and durability of the water pump.

[0050] like Figure 2 As shown, optionally, a reinforcing part 4 is provided between the water inlet pipe 31 and the water outlet pipe 32, and the reinforcing part 4 is fixedly connected to the water inlet pipe 31 and the water outlet pipe 32 on opposite sides.

[0051] It should be noted that the reinforcing part 4 effectively enhances the stability and rigidity of the overall structure by fixing the water inlet pipe 31 and the water outlet pipe 32 to resist the vibration and impact generated during the operation of the equipment, prevent structural deformation or damage caused by long-term operation, and thus extend the service life of the equipment.

[0052] Optionally, the reinforcing part 4 is provided with a support block 41, which protrudes toward the housing 1 and abuts against the housing 1 to support the drain pipe 3.

[0053] like Figure 6 As shown, the reinforcing part 4 is provided with a support block 41, and the support block 41 extends to the bottom side of the housing 1 to abut against the housing 1, so that the support block 41 is fixed relative to the housing 1. That is, the drain pipe 3 is fixed relative to the housing 1 by the support block 41. In the operating state, the support block 41 can resist the vibration and displacement caused by the impact of water flow, ensuring the stable operation of the drain pipe 3. This not only improves the overall stability of the water pump device 100, but also helps to reduce the noise and wear caused by the vibration of the drain pipe 3.

[0054] In some embodiments, an abutment block 16 protrudes from the housing 1 to the support block 41 at the abutment point of the housing 1 and the support block 41, and the abutment block 16 abuts against the support block 41;

[0055] Furthermore, the abutment block 16 and the support block 41 are provided with corresponding mounting holes and are connected by a retaining pin. The retaining pin is inserted into the abutment block 16 and the support block 41, which further fixes the abutment block 16 and the support block 41 relative to each other, resists the vibration and impact generated during the operation of the equipment, prevents loosening or falling off, and thus ensures the stable operation of the water pump device 100.

[0056] Optionally, a connecting groove 33 is formed in the inner sidewall of the connecting end of the water inlet pipe 31 and the water outlet pipe 32, and the connecting groove 33 is arranged circumferentially along the water inlet pipe 31 and the water outlet pipe 32.

[0057] like Figure 3 As shown, it should be noted that the water guide pipe is usually made of flexible hose. The flexible hose is directly inserted into the connection end of the water inlet pipe 31 and the water outlet pipe 32. After the flexible hose is inserted, it is usually tied with cable ties to prevent liquid leakage and ensure fixation. The connection groove 33 facilitates the binding and fixation of the cable ties, further improving the sealing performance and preventing liquid leakage from the connection. In addition, the cable ties are located in the connection groove 33 and are not easily moved, which improves the safety of equipment operation.

[0058] Furthermore, the connecting groove 33 is arranged circumferentially along the water inlet pipe 31 and the water outlet pipe 32, providing clear positioning and guidance for the binding of cable ties, enabling operators to complete the fixing work more quickly and accurately when binding cable ties, thereby improving installation efficiency.

[0059] Optionally, the water pump device 100 further includes a retaining member 5, the housing 1 has a connection port 15, the retaining member 5 is partially embedded in the connection port 15, and the retaining member 5 has an installation port 51 for inserting the water inlet pipe 31 and the water outlet pipe 32.

[0060] like Figure 4 As shown, it can be understood that the retaining member 5 is partially embedded in the connection port 15, so that the retaining member 5 is relatively fixed to the housing 1.

[0061] It should be noted that the cross-sectional size of the drain pipe 3 may vary depending on the model of the water pump motor 2. Therefore, in order to ensure that the drain pipe 3 passes through the housing 1, the size of the hole that needs to be opened in the housing 1 varies and cannot be standardized.

[0062] It is understood that the retaining member 5 enables the replacement of the drain pipe 3 with different cross-sectional sizes, requiring only the replacement of the retaining member 5 and the use of the mounting port 51 adapted to the cross-sectional size of the drain pipe 3, thereby improving the versatility and flexibility of the water pump device 100.

[0063] Furthermore, to save costs, the wall thickness of the housing 1 is usually small, which results in a small connection area between the drain pipe 3 and the housing 1. The equipment may vibrate during operation, potentially causing damage. The retaining member 5 can increase the contact area, and the cross-sectional shape of the mounting port 51 is adapted to the cross-sectional shape of the inlet pipe 31 and the outlet pipe 32, providing uniform contact and helping to reduce the risk of deformation or damage to the drain pipe 3.

[0064] Optionally, the retaining member 5 abuts against the inner wall of the housing 1 around the connection port 15, and the retaining member 5 abuts against the reinforcing part 4 on the side away from the connection port 15.

[0065] It is understood that the retaining member 5 can be clamped by the reinforcing part 4 and the inner wall of the housing 1, and the retaining member 5 is partially embedded in the connection port 15. The two work together to further fix the retaining member 5 without the need for additional components, which facilitates disassembly and reduces manufacturing costs.

[0066] Furthermore, the retaining pin further fixes the reinforcing part 4 and the housing 1 relative to each other, thereby further fixing the retaining member 5 held by the inner wall of the reinforcing part 4 and the housing 1 relative to the housing 1.

[0067] Optionally, the housing 1 includes a bottom wall 14 and first side walls 13 located on opposite sides of the bottom wall 14, the water pump motor 2 is located between the two first side walls 13, and the drain pipe 3 passes through the first side walls 13.

[0068] It is understood that the housing 1 is only provided with the first sidewalls 13 on both opposite sides. The water pump motor 2 can be installed into the housing 1 from the top or from the side, providing a variety of installation methods. This allows the water pump motor 2 to be flexibly selected according to different application scenarios and installation requirements, thereby enhancing the applicability and flexibility of the water pump device 100.

[0069] Optionally, the water pump device 100 further includes an upper cover 6, which is fastened to the housing 1. The housing 1 is provided with a plurality of first buckles 11, and the upper cover 6 is provided with a plurality of second buckles 61. The first buckles 11 and the second buckles 61 are fastened to each other.

[0070] like Figure 5 and Figure 6 As shown, it should be noted that the upper cover 6 and the housing 1 can be easily fixed by the mutual engagement of the first buckle 11 and the second buckle 61, without the need for additional screws or other fasteners. This simplifies the assembly process, improves assembly efficiency, and reduces assembly costs.

[0071] like Figure 2 As shown, in some embodiments, there are four of each of the first buckle 11 and the second buckle 61, and the first buckle 11 is located at the four opposite corners of the bottom wall 14 of the housing 1 to ensure uniform force distribution and improve the stability of the fastening.

[0072] It should be noted that the upper cover 6 includes a top wall 63 and second side walls 64 on opposite sides. When the upper cover 6 is fastened to the housing 1, the first side wall 13 and the second side wall 64 are adjacent. Furthermore, the upper cover 6 and the housing 1 are shaped to fit each other. When the upper cover 6 and the housing 1 are fastened together, they enclose and form an installation space for installing the water pump motor 2.

[0073] Optionally, the housing 1 is provided with a first guide portion 12, and the upper cover 6 is provided with a second guide portion 62. The first guide portion 12 and the second guide portion 62 are adapted to each other, and the second guide portion 62 is inserted into the first guide portion 12.

[0074] It should be noted that the first guide portion 12 and the second guide portion 62 enable the upper cover 6 to be accurately inserted into the housing 1 along a predetermined path and direction during the assembly process. This design not only improves the accuracy of the assembly, but also makes the assembly process more convenient and efficient, reducing the assembly difficulty and time.

[0075] Furthermore, the insertion and engagement of the first guide portion 12 and the second guide portion 62 can also provide a certain sealing effect, which helps to ensure the normal operation and safety of the water pump and extend the service life of the water pump.

[0076] like Figure 2 As shown, in some embodiments, the first guide portion 12 includes a guide groove, the extension direction of which is perpendicular to the bottom wall 14 of the housing 1, and the second guide portion 62 includes a guide protrusion, the guide protrusion and the guide groove being slidably adapted to each other.

[0077] Furthermore, the number of the first guide portion 12 and the number of the first buckle 11 are both four, and they are located at the four opposite corners of the bottom wall 14 of the housing 1. It can be understood that the number of the second guide portion 62 and the second buckle 61 are also four, and they are set corresponding to the first guide portion 12 and the first buckle 11.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
