Description

Technical Field

[0001] The utility model relates to an improved structure of a water pump body, in particular to an improved structure of a water pump body with a simplified and strengthened structure. Background Art

[0002] A pump is a device commonly used in daily life to pressurize a working fluid and increase the propulsion force of the working fluid, thereby accelerating the flow rate of the working fluid or transporting the working fluid from a low place to a high place for use.

[0003] The pump mainly has a water body, which is formed with a water inlet and a water outlet. A motor is installed on the rear side of the water body, and an impeller is provided on the front side. The rotating shaft of the motor passes through the axial hole of the water body and protrudes to the front side of the water body to connect to the impeller. When the motor operates and drives the impeller to rotate, the impeller will pressurize the working fluid flowing in from the water inlet, and then discharge the pressurized working fluid from the water outlet.

[0004] With the development of plastic material manufacturing processes and processing technologies, the performance of engineering plastics has continued to improve. Due to their advantages such as light weight, corrosion resistance, and low manufacturing costs, many mechanical parts have gradually been made of engineering plastics, replacing metal materials. However, when using engineering plastics to manufacture the aforementioned water pump body, the shaft hole formed in the water pump body suffers from insufficient structural strength due to the impact force of the motor's rotating shaft. To maintain the stability of the pump during operation, the water pump body made of engineering plastic in the prior art requires the installation of a metal ring at the shaft hole to reinforce the shaft hole. This not only complicates the structure of the water pump body but also increases the manufacturing and assembly costs. Therefore, the structure of the water pump body in the prior art still needs further improvement. Utility Model Content

[0005] In view of the problems existing in the aforementioned prior art, the invention aims to provide an improved structure of a water pump body, which has a reinforced structure and can have sufficient structural strength even if the entire body is made of engineering plastic.

[0006] In order to achieve the above-mentioned creative purpose, the technical means adopted by the present invention is to provide an improved structure of a water pump body, which includes a body body made of an integral molding, wherein:

[0007] The upper half of the fuselage body is formed with at least one flow channel;

[0008] The lower half of the fuselage body is formed with an annular wall, a partition, a socket structure and a supporting structure. The partition is arranged in the annular wall, and the periphery of the partition is connected to the inner wall surface of the annular wall. The socket structure is formed on the partition and protrudes axially backward from a rear side surface of the partition. An axial hole is formed in the socket structure. The supporting structure is formed on the rear side surface of the partition. The bottom end of the supporting structure extends toward the bottom of the water fuselage and is connected to the annular wall. The upper end of the supporting structure is connected to the socket structure. A drainage channel is formed between the supporting structure and the partition. The upper end of the drainage channel is connected to the axial hole of the socket structure, and the lower end of the drainage channel is connected to the outside of the water fuselage.

[0009] In the improved structure of the water pump body, the lower half of the body body can further form a supporting rib, which is connected to the rear side of the partition, and the bottom end of the supporting rib extends toward the bottom of the water body and is connected to the annular wall, and the upper end of the supporting rib is connected to the socket structure.

[0010] In the improved structure of the water pump body, a plurality of internal reinforcement ribs can be further formed on the body body. The internal reinforcement ribs are arranged around the sleeve structure at intervals, and each internal reinforcement rib connects the rear side of the partition and the sleeve structure.

[0011] In the improved structure of the water pump body, a plurality of external reinforcing ribs can be further formed on the body body, and the external reinforcing ribs are arranged in a grid pattern along the inner wall surface of the annular wall, and each of the external reinforcing ribs connects the rear side surface of the partition and the annular wall.

[0012] In the improved structure of the water pump body, the body can be made of engineering plastic in one piece.

[0013] In the improved structure of the water pump body, the at least one flow channel of the upper half of the body can include three flow channels, namely a water inlet flow channel, a water injection flow channel and a water outlet flow channel, and the water inlet flow channel is connected to the water injection flow channel.

[0014] In the improved structure of the water pump body, the at least one flow channel of the upper half of the body body can include a flow channel serving as a water outlet flow channel.

[0015] The advantage of the present invention is that the support structure and the support ribs can strengthen the structural strength of the sleeve structure, so that even if the water body of the pump of the present invention is made entirely of engineering plastic material, there is no need to install additional metal parts to strengthen the structure of the sleeve structure, thereby achieving the purpose of providing a water body that is light in weight, rust-resistant, has a simplified structure and high strength, and has low manufacturing and assembly costs.

[0023] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose, with reference to the accompanying drawings and preferred embodiments of the present invention.

[0024] See also Figure 1 The figure shows the pump body of the first preferred embodiment of the present invention, which includes a body AA formed in one piece. The upper portion 10 of the body AA is formed with three flow channels: an inlet channel 11, an injection channel 12, and an outlet channel 13. The inlet channel 11 is connected to the injection channel 12.

[0025] See also Figure 2 and Figure 3 As shown, the lower half 20 of the fuselage body AA is formed with an annular wall 21, a partition 22, a socket structure 25, and a support structure 26. The partition 22 is disposed within the annular wall 21, and its periphery is connected to the inner wall surface of the annular wall 21. The partition 22 has a front side and a rear side. The front side of the partition 22 and the annular wall 21 surround a water trough 23. The water inlet channel 11, the water injection channel 12, and the water outlet channel 13 are connected to the water trough 23. The rear side of the partition 22 and the annular wall 21 surround a receiving groove 24.

[0026] The sleeve structure 25 is formed on the partition 22 and protrudes axially rearward from the rear side of the partition 22. An axial hole 251 is formed in the sleeve structure 25. The two ends of the axial hole 251 respectively communicate with the water trough 23 on the front side of the partition 22 and the receiving groove 24 on the rear side of the partition 22. The pump motor is mounted on the rear side of the water body. The motor's rotating shaft passes through the axial hole 251 of the sleeve structure 25 and protrudes into the water trough 23 on the front side of the water body, thereby connecting to the impeller mounted in the water trough 23 to drive the impeller's rotation.

[0027] The support structure 26 is formed on the rear side of the partition 22. The bottom end of the support structure 26 extends toward the bottom of the water body and is connected to the annular wall 21. The upper end of the support structure 26 is connected to the sleeve structure 25 to provide support for the sleeve structure 25. A drainage channel 261 is formed between the support structure 26 and the partition 22. The upper end of the drainage channel 261 is connected to the axial hole 251 of the sleeve structure 25, and the lower end of the drainage channel 261 is connected to the exterior of the water body. Thus, when the pump is operating, working fluid that accidentally flows from the water sump 23 into the sleeve structure 25 can be discharged through the drainage channel 261, preventing the working fluid from further seeping into the reservoir 24 and damaging the motor.

[0028] like Figure 2 As shown, a plurality of internal reinforcing ribs 27 and a plurality of external reinforcing ribs 28 are further formed in the receiving groove 24 of the fuselage body AA. The internal reinforcing ribs 27 are arranged around the sleeve structure 25 at intervals, and each of the internal reinforcing ribs 27 connects the rear side surface of the partition 22 and the sleeve structure 25. The external reinforcing ribs 28 are arranged around the inner wall surface of the annular wall 21 at intervals, and each of the external reinforcing ribs 25 connects the rear side surface of the partition 22 and the annular wall 21, thereby improving the structural strength of the fuselage body AA.

[0029] See further Figures 4 to 6As shown, the water body of the pump of the second preferred embodiment of the present invention has the same integrally formed body BB as the water body of the pump of the first preferred embodiment. The lower half 20B of the body BB is formed with a ring wall 21B, a partition 22B, a sleeve structure 25B and a support structure 26B, and a drainage channel 261B is formed in the support structure 26B to communicate with the outside of the water body. The main difference between the water body of this second preferred embodiment and the water body of the first preferred embodiment is that the upper half 10B of the body BB is formed with a flow channel as the water outlet channel 13B. The water pump of this second preferred embodiment The body is used for a centrifugal pump. The working fluid to be pressurized enters the pump axially from the center of the impeller, is pressurized by the impeller, and then flows out of the pump radially through the outlet channel 13B of the body BB. The lower half 20B of the body BB is further formed with a support rib 29B. The support rib 29B is provided in the receiving groove 24B and connected to the rear side surface of the partition 22B. The bottom end of the support rib 29B extends toward the bottom of the water body and is connected to the annular wall 21B. The upper end of the support rib 29B is connected to the sleeve structure 25B, thereby further strengthening the support effect of the support structure 26B on the sleeve structure 25B.

[0030] By virtue of the design described above, the support structures 26, 26B, in conjunction with the support ribs 29B, can enhance the structural strength of the sleeve structures 25, 25B. Therefore, even if the water pump body of the present invention is entirely made of engineering plastic, there is no need to install additional metal parts to reinforce the structure of the sleeve structures 25, 25B. This achieves the purpose of providing a water pump body that is lightweight, corrosion-resistant, structurally simplified, high in strength, and has low manufacturing and assembly costs.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any simple modification, equivalent change and modification made to the above embodiment by any technician familiar with the profession without departing from the scope of the technical solution of the present invention and based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.

[0032] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims of the present invention.
