Benefits of technology

"The present invention is a toothpaste dispensing automatic toothbrush that can independently dispense toothpaste and operate the brush head. It includes a pump for selectively dispensing stored toothpaste, a first motor for operating the pump, and a second motor for moving the brush head. The toothpaste dispensing automatic toothbrush has a reservoir for storing toothpaste, a channel for interconnecting the reservoir with the brush head, and a pair of switches for separately and independently operating the brush head or dispensing toothpaste. It also allows viewing the level of toothpaste in the reservoir, is operable with a rechargeable battery, and has a refillable toothpaste reservoir."

Problems solved by technology

Although assumably effective for their intended purposes, the existing devices do not provide independently operable brush operation and refillable toothpaste dispensing operation.

Embodiment Construction

[0030] A toothpaste dispensing automatic toothbrush 10 according to the now preferred embodiment of the present invention will now be described in detail with reference to FIGS. 1a through 6d of the accompanying drawings.

[0031] In general, the toothbrush 10 includes a main body member 12, a head member 24, and a brush head 32 releasably mounted atop the head member 24. More particularly, the body member 12 includes a generally tubular construction having an ergonomic configuration (FIG. 1). The body member 12 includes opposed first 14 and second 16 ends and is generally hollow so as to define an interior space (FIG. 2c) for holding components, as will be described in more detail later. A top wall 18 encloses the body member 12 at the first end 14 thereof (FIG. 4b).

[0032] The head member 24 also includes a generally tubular configuration and defines a generally hollow interior. A lower end 26 of the head member 24 is pivotally coupled to the first end 14 of the body member with a h...

Abstract

A toothpaste dispensing automatic toothbrush includes a head member mounted atop a body member with a brush head releasably coupled to the head member. A reservoir for containing toothpaste is positioned in the body member along with a pump assembly and first motor. The first motor is connected to a battery and drives the pump assembly when actuated by depression of a first switch whereby to urge toothpaste from the reservoir through a channel and onto bristles of the brush head. The brush head includes a rotor with rotor bristles that is operatively connected to a second motor. The second motor may be energized upon actuation of a second switch to cause movement of the rotor. The invention may include a recharging base for recharging a rechargeable toothbrush battery.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates generally to automatic toothbrushes and, more particularly, to an automatic toothbrush that includes independent motors for dispensing toothpaste from a refillable reservoir and operating a brush head. [0002] Electric toothbrushes have gained a high level of popularity as consumers seek a high degree of efficiency and time savings for such a routine and repetitive task. Various devices have been proposed in the art for providing automatic brush strokes which include features such as ergonomic handles, special brush configurations, and sonic brushes that break up deposits on the teeth. Although assumably effective for their intended purposes, the existing devices do not provide independently operable brush operation and refillable toothpaste dispensing operation. [0003] Therefore, it is desirable to have an automatic toothpaste dispensing toothbrush that provides independent brush head actuation and toothpaste dispensing funct...
