Problems solved by technology

However, dampers in the prior art are usually placed horizontally, such as figure 1 As shown, when the water intake is started, the water in the buffer space is continuously converging. Due to the relatively fast flow rate of the water flow, the air in the upper part of the buffer space cannot be discharged in time. secondary noise

Embodiment 2

[0060] Such as Figure 9 , 10 , 11, the difference between this embodiment and the first embodiment is that the buffer chamber 430 includes a hollow chamber 431 and a water passage chamber 432, and the hollow chamber 431 is arranged on the outer periphery of the water passage chamber 432. Specifically, the housing 480 of the noise reducing element 400 corresponding to the water inlet chamber 420 , the buffer chamber 430 and the water outlet chamber 450 is respectively provided with a water inlet section 481 , a buffer section 482 and a water outlet section 483 . Specifically, the buffer section 482 includes an inner shell 482a and an outer shell 482b, the inner shell 482a has the water passage cavity 432, the hollow cavity 431 is formed between the inner shell 482a and the outer shell 482b, and the hollow cavity 431 is ringed. Set on the outer periphery of the water chamber 432 .

[0061] By setting a hollow cavity on the outer periphery of the water cavity, the hollow cavit...

Embodiment 3

[0071] Such as Figure 12 , 13 As shown, the difference between the present embodiment and the first and second embodiments is that: the inner wall of the water inlet chamber 420 and / or the water outlet chamber 450 is provided with a spiral rib 421 .

[0072] The high-pressure fluctuating water flow out of the booster pump passes through the water inlet chamber. Under the diversion effect of the spiral guide ribs, the water flow close to the wall of the chamber first flows along the spiral direction, and then drives the water flow far away from the wall surface, that is, close to the central axis, along the direction. A steady flow is formed in the helical direction. Then when the water flow reaches the junction of the water inlet chamber and the buffer chamber, the water flow still flows spirally under the action of inertia, but because the cross-sectional area of ​​the chamber becomes larger and the flow rate of the booster pump is constant, the flow rate of the water flow ...

Abstract

The invention relates to a noise reduction element for a water purifier. The noise reduction element is arranged on the downstream of a booster pump and comprises a shell. A water inlet and a water outlet are formed in the two ends of the shell respectively. The noise reduction element is vertically arranged, and the water inlet is located in the lower end so that the water flow speed can be reduced by means of the gravity of water flow. By the technical scheme, the speed of high-pressure water flow pressurized by the booster pump can be reduced, stable water flow is formed, and vibration andnoise generated by impact of pulsating water flow are reduced.

Description

technical field [0001] The invention relates to a noise reduction element for a water purifier. Background technique [0002] A booster pump is usually arranged in the existing water purifiers to pressurize the tap water, so as to solve the problem of insufficient tap water pressure in some places in the prior art. However, the booster pump will form a pulsating water flow to impact the pipeline during the pumping process, so when the water purifier is working, it will generate large vibrations and cause noise, especially when working at night, affecting the user experience. [0003] For this reason, in the prior art, a damper with a buffer space is provided downstream of the booster pump, and the elastic damping member therein is driven to deform when the water flows through the buffer space, so as to reduce vibration and reduce noise. However, dampers in the prior art are usually placed horizontally, such as figure 1 As shown, when the water intake is started, the water ...
