Abstract: The present disclosure provides an oral irrigator having water spray switching function, which includes a body, a nozzle and a path switching mechanism. The nozzle is provided with a first path and a second path, and the path switching mechanism is configured to communicate one of the first path and the second path with an outlet end of a piston assembly inside the body of the oral irrigator, and disconnect the other one of the first path and the second path from the outlet end of the piston assembly. The nozzle has a water outlet communicating with the first path and the second path. Water sprays from the water outlet are different when the first path or the second path is communicated with the outlet end of the piston assembly inside the body. The oral irrigator of the present disclosure can realize water spray switching without changing the nozzle.

Abstract: This disclosure provides an oral irrigator including a base, a reservoir, a handle and a starter. The base has a pumping assembly, a controller and a starting part. The reservoir has a storage cavity and is removably connected to the base and communicates the storage cavity with the pumping assembly. The handle is configured to guide fluid from the pumping assembly. The starter is provided on the handle or removably connected to the handle. One of the handle and the starter has a signal processor, and when the starting part is operated, the signal processor may receive a first starting signal and send it to the controller. The pumping assembly, the controller and the starting part are electrically connected, and when the starting part is operated, the controller receives a second starting signal. The controller controls the pumping assembly to work after receiving the first and second starting signals.

Abstract: An oral cavity cleaning device, which comprises a body, a water jet tip, a first motor, a second motor, a brush, and a water suction assembly. A rotating shaft extends out of an upper end surface of the body. The first motor drives the rotating shaft to vibrate to drive the brush to vibrate. The upper end surface of the body further comprises a water outlet, and the water jet tip is disposed on the upper end surface of the body and is in communication with the water outlet. Further, the water jet tip is disposed on a side of the brush facing a user, and the water jet tip is disposed below bristles of the brush. The second motor drives the water suction assembly to pump water from a built-in or external container, and water from a water passage disposed in the body sprays out of the water outlet and the water jet tip.

Abstract: A dual-water-tank water flosser comprises a body, a tooth-rinsing component, a first water tank, a second water tank, a first water pipe respectively connected to the first water tank and a water inlet, a second water pipe respectively connected to the second water tank and the water inlet, and a switching element. The tooth-rinsing component is installed in the body and has the water inlet and a water outlet. The first water tank and the second water tank are installed on the body. The switching element is movably disposed on the body and has two gear positions, one of the two gear positions corresponds to the switching element moving to close the first water pipe while simultaneously opening the second water pipe, and the other one of the two gear positions corresponds to the switching element moving to open the first water pipe while simultaneously closing the second water pipe.
