Problems solved by technology

[0007] A manually actuated toothbrush is shown in GB228978, but this device does not allow control over the rotation of the brush head
Additionally, there is no means of locking the brush head via a locking lever to allow manual operation

Embodiment Construction

[0028] Referring first to Figure 1 of the drawings, there is shown a hand operated toothbrush with a toothed drive belt in an unactuated mode and two brush units, the brush body and head can be separated and actuated and used in the following manner;

[0029] In FIG. 1 , the brush body shows a transmission actuated by a force F on a lever with a spring S at its pivot P. When this lever is actuated, the toothed drive belt B connecting the transmission in the brush body and the brush head rotates the brush unit multiple times through 360°. These brush units rotate in different directions, thereby eliminating any skating rotation. When the force is released from the lever, the compressive energy in the spring causes the lever to return to its original position and, in the process, counter-rotate the brush unit, drive belt and transmission within the brush body.

[0030] The transmission shown in Figure 1 allows the brush unit to rotate and counter-rotate multiple times each time...

Abstract

A hybrid design between manual and electric toothbrush technology with a mechanical rotation or manual brushing action. Brush or polishing units on the toothbrush head are rotated and counter rotated many times when activated by a spring loaded lever but when the lever is locked, the toothbrush allows a conventional manual operation. Permutations of rotary or rectangular brush or polishing units can be used on the same head. The brush units consist of bristle clusters surrounded by a ring of elastomeric nodes suspended over a cavity which moulds to teeth contours. The brush unit design is also shown applied to a manual toothbrush handle. The force applied to the lever allows variable rotation, and when slowly rotating, the bristles on the brush units can search into deep contours of teeth and gum surfaces especially at difficult to reach rear corners of teeth, rather than skipping over them at high speed.

Description

technical field [0001] The present invention relates to variable function toothbrushes. [0002] The present invention proposes a hybrid design of manual and electric toothbrushes that minimizes the inherent design flaws present in each toothbrush and combines the best features from both types of toothbrushes to produce a toothbrush with manual brushing operation as well as mechanical A toothbrush with a rotary brushing operation and an abrasive tool that does not require batteries, motors or chargers. Background technique [0003] The designs of existing toothbrushes on the market have following advantages and disadvantages: [0004] Manual toothbrushes have a large cleaning surface area, which provides good coverage of the teeth. However, this large size makes it difficult to maneuver the toothbrush in the rear corners of the teeth and limits effective brushing action and adjustment in these areas. Frayed bristles lead to the entire toothbrush being discarded. Manual t...
