Description

Noise reduction device for pulse water flow and water outlet device using same Technical Field The invention relates to the field of water purifying devices, in particular to a noise reduction device for pulse water flow and a water outlet device using the same. Background The filtering product with booster pump, when booster pump produces water, the high-frequency pulse water pressure produced by the booster pump acts on waterway and filtering membrane, at the same time the water pressure reflux acts on RO pump to produce obvious noise or abnormal sound, the noise reducing RO pump described in the prior art structure such as China patent No. 217898139U, which is based on the prior RO pump by adding some soft fixed vibration reduction measures, although the noise reducing effect can be achieved, the structure does not have targeted noise reducing measures to the pulse water flow with the most serious noise, so the noise reduction is uniform and the noise reducing effect is not obvious. Disclosure of Invention The invention provides a noise reduction device for pulse water flow, which is aimed at the characteristic that the pulse water flow in an RO pump generates large noise, and carries out multistage noise reduction on the pulse water flow in the RO pump, so that the noise generated in the working process of the RO pump is reduced. The invention provides a noise reduction device for pulse water flow, which comprises a water outlet channel and a water inlet channel, wherein a buffer chamber is arranged between the water inlet channel and the water outlet channel, the buffer chamber is of a cylindrical structure, a buffer piece is arranged in the cylindrical structure and used for smoothing the pulse water flow entering from the water inlet channel, the surface of the buffer piece, which is close to the pulse water flow, is of a bowl-shaped structure, the convex surface of the bowl-shaped structure faces the pulse water flow, and the buffer piece comprises at least one elastic structure. Preferably, the buffer member comprises a first soft rubber structure and a second soft rubber structure, the first soft rubber structure is of a bowl-shaped structure, the second soft rubber structure is located above the first soft rubber structure, the second soft rubber structure is of a cylindrical structure, and the outer surface of the cylindrical structure is of a laminated structure used for buffering. Preferably, the buffer member comprises a bowl-shaped soft rubber structure and a spring, wherein the spring is arranged above the bowl-shaped soft rubber structure and surrounds the inner wall of the buffer chamber.
