摘要：
The power dental appliance includes a handle/receiver assembly (12) and a nozzle assembly (14) which is attachable thereto. The nozzle assembly and the handle/receiver include portions which together define an interface arrangement. The nozzle includes an extending tubular member (30) with two sets of opposing sides with lateral grooves (42 44) in one set of opposing sides (38 40) near the lower end thereof. The handle/receiver includes a hollow upper portion (32) into which the tubular member portion of the nozzle fits the hollow portion including mating projections in the form of ribs (46 48) which mate with the grooves in the tubular member to prevent the nozzle from coming off the handle during operation of the appliance but permitting removal thereof by the user.
