Abstract

1275503 Oral hygiene apparatus SUNBEAM CORP 10 April 1970 [15 April 1969] 17237/70 Heading B2F [Also in Divisions F1 and F2] Oral hygiene apparatus comprises a pulsating pump connected with a handle 19 adapted to receive a removable nozzle 18, the handle including a shut-off valve manually operable by movement of the nozzle and means for controlling the amount of pulsating fluid supplied to the nozzle. As disclosed, the valve comprises a sliding cylinder 166 having slots 170 therein and actuated against a spring 171 by downward pressure on the nozzle grip 36. O-ring 167 normally seats against part 169 to prevent liquid flow. The control means, is a valve 163 having a stem 164 which engages hole 165. Rotation of sleeve 175, which has a diagonal slot 177 engaging pin 176 varies the lower limit to which part 36 can be depressed and thus adjusts the quantity of fluid flow through valve 163, and which is fed back via pipe 123 to the inlet side of the pump to prevent damaging back-pressures. All the fluid from the pump is fed back when the shut-off valve is closed. The handle may be mounted when not in use on a base which. also has supports for spare nozzles and contains the pump and a liquid reservoir. Removal or replacement of the handle actuates an on/off switch for the pump.
