ORAL CAVITY CLEANER Russian patent published in 2024 - IPC A61C17/02 

FIELD: medical equipment.

SUBSTANCE: oral cavity cleaner comprises a body, a fluid mechanism and a damper. Acoustic engine comprises a motor housing and an output power shaft. Motor housing has output axis extending in direction of output power output. Output power shaft is a columnar object passing along the output axis and penetrating through the engine housing. Output power shaft is configured to interact with the motor housing and transmit power output from the motor housing and has an axial channel parallel to the output axis, as well as a first inlet and a first outlet communicating with the axial channel. Fluid mechanism has a fluid inlet and a fluid outlet. Fluid outlet communicates with the first inlet. Housing passes in the axial direction of the output power shaft and forms a hollow cylindrical structure. Housing comprises mounting part, mounting support located in mounting part and having compartment for motor and pump compartment. Acoustic engine is installed in the engine compartment, and the fluid medium mechanism is installed in the pump compartment. Damper comprises front damping element and rear damping element. Front damping element is pushed onto the front end of the acoustic engine. Front end of the acoustic motor is installed in the mounting part by means of the front damping element. Rear damping element is pulled over the rear end of the acoustic motor. Rear end of the acoustic engine is installed in the engine compartment by means of a rear damping element.

EFFECT: reduced vibration transmitted by the motor to the handle body, reduced vibration noise and improved usability.
