Document Type and Number:
WIPO Patent Application WO/2018/120930
Kind Code:
A1
Abstract:
A water flosser, comprising a nozzle (2), a body assembly (3) and a wireless induction charging base (3-2). The nozzle (2) is connected to the body assembly (3), and the body assembly (3) is fixed on the wireless induction charging base (3-2) so as to provide charging for the body assembly (3). A handle (2-1-1) has a hollow cavity along the length thereof, a spacing board (30-1) divides the hollow cavity of the handle (2-1-1) into an upper and a lower cavity, the upper cavity having disposed therein an upper internal assembly (6) and the lower cavity having disposed therein a lower internal assembly (11). The upper internal assembly (6) includes a water pump (15), the water pump (15) having a water inlet valve plate (15-6) and a water outlet valve plate (15-6-1) therein, the water inlet valve plate (15-6) and the water outlet valve plate (15-6-1) using a piston (15-3-1) and a connecting rod (15-3) in the water pump (15) to open and close; water in a chamber of the water pump (15) in the upper internal assembly (6) moves in an upper part of the handle (2-1-1) and a sealed cavity formed by the spacing board (30-1) and the lower internal assembly (11), and cannot flow into the lower internal assembly (11), solving the problem of insufficient water flosser use life caused by damage to a PCB circuit board (20) and motor (22) due to a water pump leaking.
