Background
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 vibration damping mode of the pump mainly achieves the vibration damping effect through a buffer material, such as a rubber pad, a spring and the like, and related documents can refer to a Chinese utility model patent with a patent number of ZL201621421688.1, namely a vibration damping and oil leakage preventing vacuum pump (an authorization publication number of CN 207363839U); 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 vibration reduction 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 pump vibration.
It is found that the vibration and noise of the pump are generated by the pump body, and the water flow at the water outlet of the pump also has vibration, and the vibration is very easy to be conducted to the following load, so that the load generates resonance, and generates great noise. If we can damp the vibration of the effluent water flow, the noise, especially the noise generated by the load resonance, can be effectively reduced.
SUMMERY OF THE UTILITY MODEL
The first technical problem to be solved by the present invention is to provide a vibration-damping noise-reducing booster pump capable of reducing the vibration of the water outlet and the water inlet in view of the above technical situation.
The second technical problem to be solved by the present invention is to provide a water purifier capable of reducing vibration in view of the above technical situation.
The technical scheme adopted by the utility model for solving the first technical problem is as follows: the vibration-damping noise-reducing booster pump comprises a pump body, wherein one end of the pump body is provided with a water inlet port and a water outlet port, and the vibration-damping noise-reducing booster pump is characterized by further comprising
A housing externally disposed outside the pump body;
the vibration damping sleeve is sleeved in the middle of the pump body and is positioned in the shell;
the damping pad is arranged at one end of the pump body, is positioned in the shell and is close to the water inlet port and the water outlet port; and
and one end of the spring is abutted against the vibration damping pad, and the other end of the spring is abutted against the inner wall of the shell.
Furthermore, the inner wall of the vibration damping sleeve is provided with vibration damping convex grains which are contacted with the outer wall of the pump body, and the convex grains have elasticity and can play a good vibration damping effect.
The inner wall of the shell is provided with a limiting cylinder, and correspondingly, the outer wall of the vibration damping pad is provided with straight convex ribs matched with the inner wall of the limiting cylinder. The straight convex ribs contact with the inner wall of the limiting cylinder to play a role in vibration reduction.
Furthermore, a groove is formed at the bottom of the limiting cylinder, and the spring is arranged in the groove.
The end face of the vibration damping pad, which is in contact with the pump body, is provided with an annular convex rib, and the pump body is in contact with the inner wall of the limiting cylinder to play a role in vibration damping.
And a gasket is arranged at one end of the shell, which is far away from the vibration damping pad, and the gasket protrudes out of the outer surface of the shell. The gasket can absorb the vibration of the shell and can not be transmitted to other components.
The technical scheme adopted by the utility model for solving the second technical problem is as follows: a water purifier with a vibration-damping noise-reducing booster pump comprises a machine shell and the booster pump arranged in the machine shell.
The casing has the installation inner chamber, and this installation inner chamber one side opening supplies the booster pump to put into, and the narrow outer width in this installation inner chamber cross-section is horn mouth form to, be equipped with the amortization cotton at the opening part. The horn mouth-shaped mounting inner cavity can collect noise and transmit the noise to the opening, and the silencing cotton at the opening just absorbs the noise to achieve the purpose of reducing the noise.
And a vibration reduction counterweight is arranged between the silencing cotton and the inner wall of the shell. The vibration reduction counterweight is beneficial to absorbing the vibration brought by the booster pump and is not transmitted to the machine shell.
Compared with the prior art, the utility model has the advantages that: the vibration damping pad is combined with the spring and is arranged close to water inlet and outlet, so that the vibration of water flow can be effectively absorbed, the vibration damping sleeve can eliminate the vibration generated by the pump body and is packaged by the shell, and the vibration generated by the whole pump body can not be transmitted into the water purifier as far as possible.
