[0002] As people have higher and higher performance requirements for water appliances such as water purifiers, high-speed and high-power water pumps, such as diaphragm pumps, have also begun to be applied to water appliances; although the use of high-speed and high-power pumps has improved the water appliances performance, but it brings huge noise and vibration at the same time, which seriously affects the user experience; because the diaphragm pump itself has the characteristics of flow pulsation, and flow pulsation will cause pressure pulsation in the water pipe, resulting in the outlet pipe connected to the outlet of the pump The vibration of the main body of the water appliance is induced, which is one of the main sources of noise of the water appliance, and the existing water appliances cannot suppress the noise well

The present invention relates to the technical field of fluid noise reduction, and in particular to a water flow pressure pulsation attenuation device and water home appliances. It is an air bag cavity and a liquid cavity, and the air bag cavity is filled with an air bag; a baffle plate is provided in the liquid cavity, and the baffle plate separates the liquid cavity into a liquid inlet cavity and a liquid outlet cavity, and the inlet The liquid chamber and the liquid outlet chamber are connected to each other; the liquid outlet chamber is connected with a liquid outlet, and the liquid outlet is connected with a water outlet pipe, and the liquid inlet chamber is provided with a liquid inlet, and the liquid inlet is used for It is connected with the outlet end of the water pump; the water flow pressure pulsation attenuation device of the present invention is provided with an air bag, and absorbs the pressure pulsation of the water flow through the air bag, which reduces the vibration of the water outlet pipe connected to the water pump outlet end, thereby reducing the vibration of the body. Vibration, effectively suppress noise.
