Abstract

The H Shape Toothbrush is for the daily use of cleaning teeth. Its toothbrush head is in H shape. Inside the H shape toothbrush head, brushes extend inward facing the top, front and back of teeth as well as gums on both top and bottom jaw. During tooth brushing, it cleans all surfaces of the teeth and cleans/massages gums at same time in every stroke, which makes it very efficient. It minimizes the hard to reach areas on the back of teeth for the ordinary toothbrush, which makes it more effective on tooth cleaning. Elastic materials are used to allow the toothbrush head deforming to fit with teeth of different sizes. 8 humps are designed inside the H shape toothbrush head to control the deformation. A toothbrush handle is designed that it can rotate with respect to the H shape toothbrush head for convenient use.

Description

    BACKGROUND OF THE INVENTION
  • The H shape Toothbrush is an intended improvement over the U shape Toothbrush applied for patent (Ser. No. 12/554,880) by the author in 09-05-2009.
  • The H shape Toothbrush not only has all the benefits of U shape Toothbrush for thoroughly cleaning different surfaces of the teeth and cleaning/massaging gums at same time, but also cleans the teeth on both top and bottom jaw at same time. It doubles the efficiency of cleaning teeth and cleaning/massaging gums comparing to the U shape Toothbrush. H shape Toothbrush is a useful tool for maintaining the dental health.
  • SUMMARY OF THE INVENTION
  • The H shape Toothbrush is an intended improvement over the U shape Toothbrush, all the objectives for inventing the U shape Toothbrush are still valid for the H shape Toothbrush. Those objectives are repeated here with minor modification and addition.
  • The first objective of the present invention is to provide a toothbrush that can minimize the hard to reach areas especially on the back of the teeth for the ordinary toothbrush to make the tooth brushing more effective.
  • The second objective of the present invention is to provide a toothbrush that can clean the top, front and back of teeth at same time, and clean the teeth on both top and bottom jaw at same time in every brushing stroke to make the tooth brushing more efficient.
  • The third objective of the present invention is to provide a toothbrush that can follow the tooth profile and automatically adjust itself to fit teeth of different sizes.
  • The fourth objective of the present invention is to provide a toothbrush that uses a H shape toothbrush head moving along teeth like a train moving along its rail track to make the tooth brushing fun and enjoyable.
  • The fifth objective of the present invention is to provide a toothbrush that uses a toothbrush handle that can rotate with respect to the toothbrush head to allow the H shape toothbrush head moving all the way along teeth from one end to the other end continuously and smoothly to make the tooth brushing more convenient.
  • DETAILED DESCRIPTION OF THE INVENTION
  • FIGS. 1-10 are used to describe the invention. Those Figures are simple, straightforward and self-explanatory. References to those FIGs are listed here as the description of the invention.
    • 1. The H Shape Toothbrush comprises a H shape toothbrush head and a toothbrush handle as shown in FIGS. 1, 3, 6, 7, 8 and 9.
    • 2. The toothbrush handle is assembled onto the H shape toothbrush head through a toothbrush handle assembly which allows the toothbrush handle to rotate with respect to the H shape toothbrush head as shown in FIGS. 1, 3, 6, 7 and 8.
    • 3. The H shape toothbrush head comprises 3 elastic material parts and 5 hard plastic parts. 2 elastic material parts connect the 5 hard plastic parts together to form a H shape toothbrush head with elasticity. Another elastic material part connects the H shape toothbrush head with the toothbrush handle assembly. The 5 hard plastic parts have brushes extending inward from their inner surfaces of the H shape toothbrush head facing the top, front and back of teeth on both top and bottom jaw.
    • 4. The H shape toothbrush head has 8 humps on the inner surfaces of 2 hard plastic parts for controlling the deformation of the U shape toothbrush head. The locations of the 8 humps are shown most clearly in FIGS. 10A, 10B and 10C.
    • 5. FIGS. 10A, 10B and 10C also illustrates the H shape toothbrush head following the tooth profile and deforming to fit teeth of different sizes through using elastic material and hump design.
    DESCRIPTION OF THE DRAWINGS
  • FIGS. 1-12 show the H Shape Toothbrush of the present invention.
  • FIG. 1 is the Perspective View of the H Shape Toothbrush.
  • FIG. 2 is the Front View of the H Shape Toothbrush.
  • FIG. 3 is the Side View of the H Shape Toothbrush.
  • FIG. 4 is the Cross Section View of the H Shape Toothbrush.
  • FIG. 5 is the Back View (from handle side) of the H Shape Toothbrush.
  • FIG. 6 is the Cross Section View of the Toothbrush Handle Assembly of the H Shape Toothbrush.
  • FIG. 7 is the Top View of the H Shape Toothbrush.
  • FIG. 8 is the Bottom View of the H Shape Toothbrush.
  • FIG. 9 is the Top View of the H Shape Toothbrush Handle.
  • FIG. 10 consists of FIG. 10A, FIG. 10B and FIG. 10C.
  • FIG. 10A illustrates that the large teeth touches the humps inside the H shape toothbrush head and forces the toothbrush head to open wider to fit the large teeth.
  • FIG. 10B illustrates that the small tooth does not touch the humps and the elasticity from the elastic materials on the H shape toothbrush head contracts the toothbrush head.
  • FIG. 10C illustrates that the H shape toothbrush head moving along the teeth following the tooth profile.
