1. An oral care device, comprising: a handle part and a care head part, wherein the handle part is configured to be suitable for hand-holding, and the handle part comprises:
an acoustic motor, comprising a motor body and a power output shaft, wherein the motor body has an output axis extending in a power output direction, the power output shaft is a column extending along the output axis and penetrating through the motor body, the power output shaft is configured to cooperate with the motor body and transmit output power of the motor body, and the power output shaft has an axial channel parallel to the output axis; and
an outer shell, having an outer wall and accommodating cavities enclosed by the outer wall, wherein the accommodating cavities comprise a mounting cavity and a water storage cavity which are separated from each other, and an extension direction of the mounting cavity is consistent with an extension direction of the output axis; the power output shaft and the motor body are mounted in the mounting cavity, and one end, adjacent to the care head part, of the outer wall is provided with a mounting shaft hole which allows the power output shaft to penetrate and forms an assembly fit with the power output shaft;
the care head part has a flushing stem parallel to the output axis and a brush head arranged on a head of the flushing stem, wherein the flushing stem is mounted on the power output shaft, the brush head comprises bristles and a spray head, the bristles extend in a direction at a preset angle with the output axis, an orientation of a nozzle of the spray head is the same as an orientation of the bristles, and the flushing stem has a fluid channel capable of communicating the spray head with the axial channel;
along the extension direction of the output axis, the axial channel has an inlet and an outlet, the inlet of the axial channel is capable of communicating with the water storage cavity, and the outlet of the axial channel is capable of communicating with the care head part; and during use of the oral care device, water in the water storage cavity can enter the axial channel through the inlet of the axial channel, flows from a first end of the motor body through the motor body to a second end thereof through the axial channel, then enters the care head part from the outlet of the axial channel, and sprays out from the brush head of the care head part;
the oral care device further comprising a fluid mechanism and a battery; the acoustic motor, the fluid mechanism and the battery are arranged sequentially along a direction parallel to the output axis.
