Problems solved by technology

It is generally more difficult to get the nozzles in place correctly for the rear teeth than for those teeth that are closer to the front
Positioning the nozzle properly is difficult for the user as the spray cannot be directly felt and the rear teeth cannot be easily seen
[0005] In fact, for the interproximal area of ​​the tooth, the nozzle is relatively easy to be improperly seated
This results in reduced or poor cleaning in the interproximal area.

Embodiment Construction

[0012] figure 1 A hand-held drop spray tooth cleaning implement is shown generally at 10 . A hand-held appliance suitable for domestic use includes a hand-held portion 12 in which a reservoir source of liquid 14 is located. In one embodiment, liquid such as water from the reservoir and air from the environment are directed by separate pumps 20 and 22 to the spout and guide assembly portion 16 of the appliance. The user interface 25 controls the actions of the appliance. Power is supplied by a power pack 23 such as a battery, while the appliance is controlled by a microprocessor (electronics) 24 . At the spout and guide assembly 16, the flow of gas (air) from the pump 22 generates droplets from the liquid supplied by the reservoir 14 and then accelerates the generated droplets to all points from the nozzle portion 30 of the appliance onto the teeth. Desired velocity of departure from a desired position on the tooth, in particular the interproximal area of ​​the tooth.

Abstract

The guide assembly is used for precise cleaning of the interproximal spaces of the teeth. The guide assembly includes a base portion (30) for contacting the surface of the tooth and gum area adjacent the interproximal space, the base portion being approximately 12 mm in diameter to provide stable contact with the tooth and gum area. The guide assembly also includes a tip portion (28) extending forwardly from the base portion and including an opening (31) through which the droplet spray is directed in line with the plane of the interproximal space.

Description

technical field [0001] The present invention relates generally to liquid droplet spray tooth cleaning implements, and more particularly to a guide assembly for positioning a liquid droplet spray for interproximal cleaning of teeth. Background technique [0002] Droplet spray tooth cleaning implements are known and described in several patents and published patent publications. One such patent publication is WO200507034 owned by the applicant of the present invention, the content of which is hereby incorporated by reference. [0003] This publication teaches an appliance system for generating liquid, such as water, in the form of droplets and then accelerating those droplets to a desired velocity by a gas flow, such as air. Other appliance systems use other arrangements to generate and accelerate droplets. The droplets must be of a specific size and velocity to produce effective tooth cleaning. [0004] Many of these appliances are designed for home use, requiring the user...
