Patent DE-4306527-A1 (DE)
Title: Travelling mouth douche
Inventor: HEEL KLAUS DIPL ING
IPC: A61C17/02
Filed: 1993-03-03
Abstract: The invention provides a high standard of oral hygiene outside the home, especially in the office, on journeys or in leisure time. The advantages of mouth douches over tooth brushes are known. Those travelling professionally, in particular, should not be deprived of these advantages. This travelling mouth douche is distinguished in that water tank, motor pump, controller and spray nozzle are accommodated in one housing which can be held and operated by one hand. The pumping strength of the water jet is infinitely controlled with the thumb via a slider control, and on release of this control it jumps back to the 0 point and switches the pump off. Thus, different cleaning situations can always be dealt with spontaneously and sensitively. The connection cable is designed as a spiral spring which avoids excessive sagging during use and ensures high mobility. For transportation, the motor part is unscrewed from the water tank, rotated by 180 DEG  and screwed on again with the nozzle pointing inwards. The device is thus reduced in size by about one third. The spiral cable wraps itself almost automatically around the device.   The covering hood is screwed on to the open pump end of the motor part. Thus, the device is packaged completely hygienically by itself.
