A compact liquid-outlet system comprising a liquid pump device, a liquid-inlet flow channel, and a liquid-outlet flow channel and an oral cleaning method. The liquid pump device comprises a liquid pump cavity, a piston slidably disposed in the liquid pump cavity, and a piston rod. The piston rod extends through the liquid pump cavity in a liquid-tight manner and is connected to the piston. The piston divides a pump chamber of the liquid pump cavity into a rod chamber and a rodless chamber. The piston comprises a liquid-outlet one-way valve allowing only liquid to flow from the rod chamber to the rodless chamber. The liquid-inlet flow channel communicates with the rod chamber through a liquid-inlet one-way valve. The liquid-outlet flow channel communicates with the rodless chamber. This system eliminates the need of extra space for installing the liquid-outlet one-way valve, resulting in a more compact structure.

The present application belongs to the field of electric toothbrushes. Provided are a conductive structure of a sonic vibration motor, an electric toothbrush and a brush head power supply structure thereof. The conductive structure comprises a sonic vibration motor body, a hollow conductive motor shaft and a conductive assembly. The motor shaft of the sonic vibration motor is implemented as a hollow conductive structure, the inside thereof serving as a wiring channel; the conductive assembly passes through the body along the central axis of the motor shaft and is externally connected, so as to form a first conducting circuit; and the motor shaft itself serves as a second conducting circuit by means of the conductivity property thereof. Two ends of the two conducting circuits are respectively connected to an electric element and a power supply to form a circuit. Thus, by means of fully utilizing the features of the structure of the sonic vibration motor itself, the present application simply needs to configure the motor shaft to be hollow, and does not need significant structural modification on the motor. Since a first power connection output end and a second power connection output end are both integrated on the motor shaft itself, although the motor vibrates reciprocatingly at a high frequency, the power connection efficiency is not affected, and extra wiring layout is not needed. In addition, the two output ends allow externally-assembling installation, thereby achieving advantages in both safety and convenience.
