1. An oral cavity cleaning device, comprising:
a sonic 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 columnar object 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 a first inlet and a first outlet communicating with the axial channel;
a fluid mechanism, having a fluid inlet and a fluid outlet, wherein the fluid outlet communicates with the first inlet;
a housing, extending in an axial direction of the power output shaft and forming a tubular structure with a hollow interior, wherein the housing comprises a core mounting part, a mounting rack is arranged in the core mounting part and has a motor chamber and a pump chamber, the sonic motor is mounted in the motor chamber, and the fluid mechanism is mounted in the pump chamber;
wherein,
a front cushion, arranged at a front end of the motor body in a sleeved manner, wherein the front end of the sonic motor is mounted in the core mounting part by the front cushion; and
a rear cushion, arranged at a rear end of the motor body in a sleeved manner, wherein the rear end of the sonic motor is mounted in the motor chamber by the rear cushion;
wherein, multi-point elastic contact is formed between a periphery of the mounting rack and an inner wall of the core mounting part;
a plurality of first elastic bosses are arranged on the periphery of the mounting rack at intervals in an extending direction of the output axis, and the multi-point elastic contact is formed between the mounting rack and the inner wall of the core mounting part by the first elastic bosses;
the mounting rack comprises a mounting seat, the motor chamber is arranged in the mounting seat, mounting side plates are respectively arranged on two opposite sides of the mounting seat, the two mounting side plates extend away from each other, and the first elastic bosses are arranged at edges of the mounting side plates away from the mounting seat;
slots penetrating each of the mounting side plates in a thickness direction are formed in the mounting side plates, and connecting arms located on one side of each of the slots away from the mounting seat protrude in a direction away from the mounting seat to form the first elastic bosses.
