摘要:
The invention relates to a dental cleaning device for simultaneously brushing at a plurality of dental positions. The device consists of a mouthpiece having a pressure chamber and a U-shaped recess delimited by a flexible and deformable wall. The pressure chamber contains a fluid under pressure. A plurality of bristles is attached to the wall and extending from the wall into the recess. A pump is in fluid communication with the pressure chamber. The pump reciprocatingly increases and decreases the pressure in the pressure chamber thereby deforming the wall and moving the wall back and forth. The dental cleaning device further includes a pressure sensor for measuring a pressure in the pressure chamberand a controller configured to generate a control signal in dependence on the pressure measured by the sensor. The pump is configured to provide a delivery into and/or out of the pressure chamber in response to the control signal. The controller is configured to reduce the delivery of the pump when the pressure in the pressure chamber exceeds a predetermined upper threshold and/or to operate the pump at a fixed frequency.The invention relates to a dental cleaning device for simultaneously brushing at a plurality of dental positions.
