Toothbrush with large bristle surface area
Abstract
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.

Claims
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.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] 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.
[0003] 2. Description of the Prior Art
[0004] 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
[0005] 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.
[0006] 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
[0007] This invention is better understood by referring to the
accompanying drawings, wherein:
[0008] FIG. 1 is a perspective view of the preferred embodiment of
a toothbrush with large bristle surface area in the present
invention;
[0009] FIG. 2 is a magnified end view of the brush head in the
present invention; and
[0010] 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
[0011] As shown in FIGS. 1.about.3, the preferred embodiment of the
toothbrush with large bristle surface area in this invention
comprises a brush handle 1 and brushing head 2.
[0012] 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.
[0013] 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).
[0014] These bristles can be designed for a traditional manual
toothbrush or act as a separate brush head part in conjunction with
an electric toothbrush.
[0015] 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.
