This invention is a toothbrush with large bristle surface area, primarily
comprising a brush handle and a brush head with large enclosed surface,
the brush surface is an all-dimensional contour shape, allowing a simple
brushing motion to cover most of the teeth's surface and clean the teeth
from left to right, top and bottom, inside and outside, and also at
masticatory surfaces all at once, thereby saving time needed to brush
teeth and cleaning all surfaces and details of the teeth more thoroughly.
1. A toothbrush with large bristle surface area, comprising: a brush head
at the end of a brush handle, with upright bristles on the 3 brushing
surface to cover as much the teeth surface at once; its major
distinguishing characteristics are that the brushing surface is in a
surrounding contour shape, and the inside surface of the H shaped have
three-directional perpendicular bristles; and allowing the user to
simultaneously cover and clean the teeth from left to right, top and
bottom, inside and outside, and at masticatory surfaces, thereby
achieving the purpose of fully clean the teeth yet also saves time.
2. A toothbrush with large bristle surface area as claimed in claim 1, wherein the length of said brushing surface exceeding 8 centimeters, thereby allowing users to brush a larger area of their teeth at once.
3. A toothbrush with large bristle surface area as claimed in claim 1, wherein said brushing surface is in a shape similar to an H, the flexible tubes or flexible bristle can be adopted in order to adjust the radian of the arc of said brushing surface.
BACKGROUND OF THE INVENTION
 1. Field of the Invention
 The present invention provides a type of toothbrush with a large bristle surface area, the all-dimensional surrounding bristles allowing the user to clean teeth with a simple motion and also save time brushing teeth. It also provides young children, the elderly, and physically challenged people a more convenient way to clean teeth.
 2. Description of the Prior Art
 As most typical toothbrushes are comprised of a straight handle and limited brushing surface, users can only brush their teeth bit by bit, which is not only inefficient but also highly inconvenient for users.
SUMMARY OF THE INVENTION
 The main objective of this invention is to provide a toothbrush large size all-dimensional surrounding contour bristles, providing greater ease of use and convenience to users when brushing their teeth.
 The major distinguishing characteristic of this invention is that the large brushing surface is in a surrounding contour shape covering most teeth surfaces at once. The inner surfaces of the brush are fitted with bristles to cover most surfaces and detail while brushing teeth.
BRIEF DESCRIPTION OF DRAWINGS
 This invention is better understood by referring to the accompanying drawings, wherein:
 FIG. 1 is a perspective view of the preferred embodiment of a toothbrush with large bristle surface area in the present invention;
 FIG. 2 is a magnified end view of the brush head in the present invention; and
 FIG. 3 is a perspective view of the toothbrush with large bristle surface area in using condition in the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
 As shown in FIGS. 1˜3, the preferred embodiment of the toothbrush with large bristle surface area in this invention comprises a brush handle 1 and brushing head 2.
 The brushing head 2 is in an all-dimensional contour shape, with its ends in the shape of an "H". The length of the brushing head 2 is over 8 centimeters, and the inside surfaces of the H shape have three-directional perpendicular bristles 20, 21, 22 of which 20 and 22 are horizontal, with a gap 23 as wide as the thickness of a tooth between the ends of the bristles 20, 22 as well as flexible tubes 24 within the brushing head 2.
 When using, the user need only spread toothpaste within the gap 23 and begin to brush. Because the three-directional bristles 20, 21, 22 brush the teeth (A) on three surfaces simultaneously, and the flexible tubes 24 on the brushing head can be used to adjust the radian of the arc for users of different ages, the teeth (A) are thoroughly cleaned, users are able to achieve the purpose of saving time brushing their teeth yet also fully clean their teeth (A).
 These bristles can be designed for a traditional manual toothbrush or act as a separate brush head part in conjunction with an electric toothbrush.
 While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
