In our lives, various pump products are often accessible. The pump brings great trouble to us while providing convenience to us. For example, the booster pump used in water purification products has a serious trouble in generating vibration and noise during operation.

At present, in the products in the market, the damping mode of the pump mainly achieves the damping effect through a buffer material, such as a rubber pad, a spring and the like, and related documents can refer to a damping oil-leakage-prevention vacuum pump (an authorization publication number CN207363839U) in a Chinese utility model patent with a patent number of ZL 201621421688.1; reference may also be made to the chinese utility model patent No. ZL201721266750.9, a water pump damping device (granted publication No. CN 207229368U).

However, the existing damping effect cannot achieve the ideal effect of people, and vibration is easily transmitted to other parts, such as a shell of a product. There is a pressing need for a treatment that effectively reduces the pump shock.

In addition, besides the pump itself, the pipeline vibration of the water outlet of the pump is also very large. The vibration of the water outlet can cause the parts connected with the water outlet pipe to vibrate simultaneously, and generate larger noise. It is also highly desirable to reduce the vibration of the pump outlet.

Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

In embodiment 1, as shown in fig. 1 and fig. 2, in this embodiment, a pump body 1 has a water inlet port and a water outlet port, the water inlet port is provided with a water inlet pipe 14, the water outlet port is provided with a water outlet pipe 13, the water outlet pipe 13 is bent and arranged on one side of the pump body 1, the water outlet pipe 13 is provided with a first damping assembly 3, and a housing 12 of the pump body 1 is provided with a second damping assembly 4. The pump body 1 is transversely arranged, the bottom of the pump body is provided with a mounting and connecting plate 5, and the lower end of the mounting and connecting plate 5 is provided with a buffer cushion block 51.

Since the vibration of the outlet pipe 13 is relatively larger than that of the inlet pipe 14, it is preferable to provide the outlet pipe 13 with a shock absorbing structure.

Referring to fig. 3, the first damping assembly 3 includes a first damping member 31 and a first counterweight 32 disposed on the first damping member 31, and the first damping member 31 is annular and sleeved on the water outlet pipe 13. The first damper member 31 includes an inner ring 311 and an outer ring 312 concentrically arranged, the inner ring 311 and the outer ring 312 having a damping gap 314 therebetween and connected by a radial connecting arm 313, and the first weight 32 is provided on the outer ring 312. The first weight 32 is fitted to the outer ring 312 by integral molding. The first weights 32 in this embodiment are three and are uniformly arranged on the outer ring 312.

Referring to fig. 4, the second damping assembly 4 includes a second damping member 41 and a second counterweight 42 disposed on the second damping member 41, and the second damping member 41 is annular and sleeved on the outer casing 12 of the pump body 1. The second weight 42 is fitted to the second damper 41 by integral molding. The second balance weights 42 in this embodiment are three and uniformly arranged on the second damping member 41.

In order to firmly connect the second shock absorbing assembly, the pump body 1 has an end cap 11, the end cap 11 extends outwardly to form a connecting skin 111, and the connecting skin 111 is integrally connected to one side of the second damping member 41 through a connecting member 6.

The first damping member 31 and the second damping member 41 may be made of rubber, silica gel, pitch, or coal tar.

When the water outlet pipe 13 vibrates, the inner ring 311 is stressed firstly to obtain primary buffering, and if the vibration is large, the vibration is transmitted to the outer ring 312 to perform secondary buffering, so that the shock absorption is further realized.

When the pump body 1 vibrates upwards, the second counterweight 42 counterweight at the lower part (or side) of the pump has a downward pulling force on the pump due to the gravity and inertia of the second counterweight 42. In this way, the pump vibrations are counteracted. The vibration principle in other directions is the same. The damping mechanism that damping piece and counter weight constitute is established to the cover on the shell of the pump body, can promote the shock attenuation effect effectively, again because the damping piece is direct cover locate the pump body shell on, the vibrations that the pump body operation in-process produced are directly absorbed by the damping piece, can not conduct for other parts, can not take place vibrations and be enlargied or turn into the condition of noise, further reach vibration/noise reduction's purpose

Compared with the direct use of the buffer material or the spring, the vibration is not conducted to other components, so that the vibration is amplified or converted into noise.

Embodiment 2, as shown in fig. 5, the outer ring 312 of the first damping member in this embodiment is closely attached to the housing 12 of the pump body. Thus, the first damping member has a certain damping effect on the casing of the pump body. Other structures refer to example 2.

Therefore, the two sides of the shell of the pump body are tightly attached by the first damping parts, the left-right shaking is well controlled, and the first damping component 3 simultaneously plays a role in damping the pipeline and the pump body. Other structures refer to example 2.
