Description

Technical Field

[0001] This utility model relates to the field of water pump noise reduction technology, and in particular to a low-noise water pump assembly. Background Technology

[0002] Water pumps are widely used in various industries. When water pumps are running, the operating pressure is high and the motor speed is at least 1000 r / min. This not only causes the water pump itself to vibrate, but also causes the connected outlet pipe to vibrate strongly. This situation not only affects the stability of the pump foundation, but also generates a lot of noise, resulting in a poor user experience and room for improvement. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art and provide a low-noise water pump assembly. It reduces the vibration energy of the water outlet pipe through the first toothed structure of the first flexible member, and at the same time prevents the vibration energy of the pump body from being transmitted to the front and rear supports through the second toothed structure of the second flexible member. This avoids the risk of noise amplification, realizes the low-noise operation of the water pump assembly, and ensures the user experience.

[0004] To achieve the above objectives, this utility model provides a low-noise water pump assembly, including a front bracket, a rear bracket, a pump body, and a water outlet pipe. The pump body is fixedly clamped between the front bracket and the rear bracket, and the water outlet pipe is connected to the water outlet of the pump body. The water outlet pipe is fitted with a first flexible component, which has a through hole and a first tooth-like structure is provided circumferentially on the hole wall. A second flexible member is provided between the front support and the rear support, and the second flexible member is fitted onto the outer wall of the pump body. The second flexible member has a second tooth-like structure on at least the wall surface that abuts against the front and rear supports.

[0005] The second flexible member is further configured such that: the second flexible member includes a first contact portion located in the middle and used to fit against the outer wall of the pump body, and a second contact portion disposed outside the first contact portion; the second contact portion includes abutment walls disposed at intervals on opposite sides of the contact portion and used to abut against the front and rear supports respectively; the abutment walls are provided with a second tooth-like structure.

[0006] The second contact portion is further configured as a cover structure, and the first contact portion is located in the middle of the cover of the second contact portion.

[0007] The configuration is further defined as follows: the inner end face of the first contact portion protrudes beyond the inner end face of the second contact portion, and the inner end face of the first contact portion is an arc-shaped structure adapted to the outer wall of the pump body.

[0008] Further configured such that the first contact portion has several through holes.

[0009] The via shape of the first flexible component is further configured as follows: the via shape is rectangular or triangular.

[0010] A further configuration is provided: an annular groove is provided around the outer edge end face of the first flexible member.

[0011] Further configuration: Both the first flexible component and the second flexible component are integrally molded rubber or silicone components.

[0012] Compared with the prior art, the present invention has a simple and reasonable structure.

Detailed Implementation

[0015] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] This utility model discloses a low-noise water pump assembly, such as... Figure 1As shown, the system includes a front support 2, a rear support 3, a pump body 1, an outlet pipe 4, a first flexible component 5, and a second flexible component 6. The outlet pipe 4 is connected to the outlet of the pump body 1. The first flexible component 5 is fitted onto the outlet pipe 4 to absorb vibrations in the pipeline and reduce noise. The second flexible component 6 is fitted onto the pump body 1. The front support 2 and the rear support 3 are positioned on the front and rear sides of the pump body 1 and press against the front and rear sides of the second flexible component 6 to clamp and fix the pump body 1. In this way, the second flexible component 6 can effectively prevent the vibration energy generated by the pump body 1 from being transmitted to the front and rear supports 3, effectively avoiding the risk of increased noise.

[0017] In this embodiment, as Figure 2 As shown, the first flexible component 5 is an integrally molded rubber or silicone component, which has a through hole and a first toothed structure 51 is circumferentially arranged on the inner wall of the through hole. The width of the internal space formed by the toothed ends of the first toothed structure 51 is adapted to or slightly smaller than the diameter of the water outlet pipe 4. In this way, the deformation of the first toothed structure 51 can effectively reduce the vibration energy of the water outlet pipe 4, avoid resonance, reduce noise, and avoid the risk of noise amplification. The through hole on the first flexible component 5 is rectangular or triangular, or other shapes can be used. Specifically, the outer edge end face of the first flexible component 5 is also provided with an annular groove 52, which can reduce material consumption and lower costs while ensuring the performance of the first flexible component 5.

[0018] In this embodiment, as Figure 3 and Figure 4 As shown, the second flexible member 6 is an integrally molded rubber or silicone part, which includes a first contact portion 61 located in the middle and used to fit against the outer wall of the pump body 1, and a second contact portion 62 disposed outside the first contact portion 61. The second contact portion 62 includes abutment walls disposed at intervals on opposite sides of the contact portion and used to abut against the front and rear supports 3 respectively. The abutment walls are provided with a second toothed structure 621 that abuts against the supports. Specifically, the second contact portion 62 is a cover structure. The first contact portion 61 is located in the middle of the cover of the second contact portion 62 and there is a gap between the two. The second toothed structure 621 is disposed around the outer periphery of the first contact portion 61. In this way, the gap between the first contact portion 61 and the second contact portion 62 effectively reduces the energy transfer between the two. At the same time, the deformation of the second toothed structure 621 can reduce the energy transfer between the second contact portion 62 and the supports. Thus, the second flexible member 6 can prevent the vibration energy of the pump body 1 from being transferred to the front and rear supports 3, avoid resonance, reduce noise, and avoid the risk of noise amplification.

[0019] In the above scheme, such as Figure 3As shown, the inner end face 611 of the first contact portion 61 protrudes beyond the inner end face 611 of the second contact portion 62, and the inner end face 611 of the first contact portion 61 is an arc-shaped structure adapted to the outer wall of the pump body 1. This structure allows the vibration energy of the pump body 1 to be transmitted to the first flexible member 5 only through the first contact portion 61. Preferably, the first contact portion 61 is provided with a plurality of through holes 612, which can achieve the effect of noise reduction.

[0020] Compared with the prior art, the present invention has a simple and reasonable structure. The first toothed structure of the first flexible component reduces the vibration energy of the water outlet pipe, while the second toothed structure of the second flexible component prevents the vibration energy of the pump body from being transmitted to the front and rear supports. This avoids the risk of noise amplification, realizes low noise operation of the water pump assembly, and ensures a good user experience.

[0021] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
