Title:
WATER PRESSURE FLUCTUATION EXCITATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/056549
Kind Code:
A1
Abstract:
Disclosed is a water pressure fluctuation excitation apparatus, comprising: a first cover body (10), a second cover body (20) connected to the first cover body (10), and a water pressure fluctuation assembly (30) connected to the first cover body (10), wherein the first cover body (10) is provided with a water inlet cavity (11); the first cover body (10) is provided with a water inlet port (12) in communication with the water inlet cavity (11); the first cover body (10) is provided with a water outlet hole (13) in communication with the water inlet cavity (11); the second cover body (20) is provided with a water discharge cavity (21) in communication with the water outlet hole (13); the second cover body (20) is provided with a water inlet port (22) in communication with the water discharge cavity (21); the water pressure fluctuation assembly (30) comprises: an electromagnet (31) connected to the first cover body (10) and a movable metal piece (32) located inside the water inlet cavity (11); and the movable metal piece (32) is arranged relative to the water outlet hole (13). The movable metal piece (32) of the water pressure fluctuation excitation apparatus is driven by the electromagnet (31) to impact the water outlet hole in the process of a periodical reciprocating motion so as to generate pulse-type water pressure fluctuation in the water discharge cavity (21), so that a stronger cleaning effect can be achieved with less water, and a fluctuating water flow can also have a pulse massage function.
