DEVICE FOR ORAL CARE Russian patent published in 2023 - IPC A61C17/24 A46B15/00 

FIELD: medical equipment.

SUBSTANCE: oral care device includes a handle part and a head part for care. The handle part is designed in such a way that it is suitable for holding by the hand. The handle part contains an acoustic motor and an outer shell. The acoustic motor contains a motor housing. The outer shell has an outer wall and the accommodating cavities surrounded by the outer wall. The accommodating cavities include a mounting cavity and a water storage cavity separated from each other, and the maintenance head portion has a brush head containing bristles. The acoustic motor also contains a power output shaft. The motor housing has an output axis extending in the output power transmission direction, the output power shaft is a columnar member extending along the output axis and penetrating the motor housing. The output power shaft is configured to interact with the motor housing and transmit the output power to the motor housing, and the output power shaft has an axial channel parallel to the output axis. The mounting cavity runs along the outlet axis; the output power shaft and the motor housing are installed in the mounting cavity, and at one near end, corresponding to the part with the maintenance head, there is the outer wall with a hole for installing the shaft through which it is possible to pass the output power shaft to ensure a mounting fit to the output power shaft. The maintenance head portion has a flushing rod parallel to the outlet axis and has a brush head located on the head of the flushing rod. The washing rod is mounted on the output shaft, the brush head also includes a spray head, the bristles extend in a direction at a predetermined angle to the output axis, the orientation of the spray head nozzle is the same as the orientation of the bristles, and the washing rod has a fluid channel configured with the possibility to ensure communication between the spray head and the axial channel. The axial channel in the direction of passage of the output axis has an inlet hole and an outlet hole. The inlet of the axial channel is configured to communicate with the water storage cavity, and the outlet of the axial channel is configured to communicate with the care head portion; and when using the oral care device, it is possible for the water in the water storage cavity to enter the axial channel through the inlet of the axial channel, flow from the first end of the motor body to the second end thereof through the axial channel, and then enter the head part for care from the outlet of the axial channel and spraying from the brush head of the part with the care head.

EFFECT: ensuring ease of control and increasing user comfort.
