Inter-dental brush structure
Abstract
An inter-dental brush structure comprises a brush shaft
installation opening installed on the curved end of the brush
handle. A fitting bulge and a joined clip lid is each installed on
the top surface of the curved end, and the joined clip lid has a
fitting fillster installed matching the fitting bulge. The fitting
fillister of the joined clip lid can fit the fitting bulge and fix
the brush shaft inserted in the brush shaft installation opening by
pushing back the rear of the brush shaft and clip it tight to fix,
and in turn enables the installation and replacement of the brush
shaft. The brush handle in formed of two parts connected by an axis
so that it can revolve, the connecting surface has several indents
and bulges arranged in a circle to fix the location of the
revolving. The characteristic of this inter-dental brush structure
is to adjust to the angle needed for brushing the rear teeth
crevices, and increase the convenience of usage.

Description
BACKGROUND OF THE ION
[0001] (a) Technical Field of the Invention
[0002] The present invention concerns an inter-dental brush
structure, especially a kind of inter-dental brush structure with
replaceable brush shaft and brush handle, with angles adjustable,
and increase the convenience and effect of usage.
[0003] (b) Description of the Prior Art
[0004] Prior art interdental brush (please refer to FIG. 1) is
comprised of a brush handle 10 with one end installed with a brush
shaft 20. Since the brush handle 10 and the brush shaft 20 forms a
sight line, it is very inconvenient to use when brushing rear teeth
crevices. Therefore, manufacturers provided a curved end
interdental brush (please refer to FIG. 2), increasing the
convenience of usage for brushing rear teeth crevices with the
curved end 30 design. However, since the angel of the curved end 30
is fixed, and cannot be adjusted according to the required angel of
the different positions of the rear teeth crevices, it is very
inconvenient to use. Moreover, both prior art inter-dental brush
have fixed brush shaft and not replaceable, it is more costly when
discarded.
SUMMARY OF THE INVENTION
[0005] The main object of the present invention is to solve the
aforementioned defects of inconvenient usage of prior art
inter-dental brush, and provide an inter-dental brush structure
which has a brush shaft installation opening installed on the
curved end of the brush handle. A fitting bulge and a joined clip
lid is each installed on the top of face of the curved end, and the
joined clip lid has a matching fitting fillister, whereas the
fitting bulge also has a clipping fillister installed connecting
with the brush shaft installation opening. The joined clip lid has
the design of its fitting fillister covering the fitting bulge and
with the two sides form a matching shape boundary, and the front
holding part is designed to fix the fitting fillister lid. Together
with the two designs, the rear of the brush shaft inserted in the
brush shaft installation opening will be clipped tightly and fixed
in the clipping fillister. Since the clip fixing force is designed
to be tight but not too tight, it can easily be pulled apart with
fingers, and is convenient for the installation and replacement of
the brush shaft. Moreover, the brush handle is divided into two
parts, and connected with axis so that it revolves. The connecting
face has several matching indents and bulges for fixing the
locations of the revolving to adjust to the angels needed for
brushing the rear teeth crevices. The structure is unprecedented,
and not only does it possess novelty and progress, it also
increases the using effects. The foregoing object and summary
provide only a brief introduction to the present invention. To
fully appreciate these and other objects of the present invention
as well as the invention itself, all of which will become apparent
to those skilled in the art, the following detailed description of
the invention and the claims should be read in conjunction with the
accompanying drawings. Throughout the specification and drawings
identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will
become manifest to those versed in the art upon making reference to
the detailed description and the accompanying sheets of drawings in
which a preferred structural embodiment incorporating the
principles of the present invention is shown by way of illustrative
example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0013] The present invention inter-dental brush structure (please
refer to FIGS. 3, 4, 5, 5A) mainly comprises a brush handle 1 with
a brush shaft installation opening 12 installed on the curved end
11. A fitting bulge 13 and a joined clip lid 2 is each established
on the top surface of the curved end, and the said joined clip lid
2 is connected to the rim of the curved end top surface with a
flexible connecting piece 14. It has a matching fitting fillster 21
on the opposite side to the fitting bulge, and the fitting bulge 13
also has a clipping fillister 15 installed to connect to the brush
shaft installation opening.
[0014] The aforementioned joined clip lid 2 has the fitting
fillister cover the fitting bulge and with the two sides form a
matching n shape boundary, and together with the matching design of
front hooking part 16 to fix the fitting. The brush shaft 3
inserted in the brush shaft installation opening 12 is then pushed
back in the rear and clipped tightly to fix in the clipping
fillister 15. Since the clip fixing force is designed to be tight
but not too tight, it can be pulled apart by fingers. Not only is
it convenient to install and replace the brush shaft 3, but also
beneficial to discard the brush shaft when damaged without losing
the brush handle and save the cost.
[0015] Moreover, the brush handle 1 of the present invention is
formed with two parts, and connected with an axis so that it
revolves. The connecting surface has several indents and bulges 17
spread and arranged in a circle to fix the locations of the
revolving. This is to adjust the angles needed for brushing rear
teeth crevices, and in turn increase the convenience of usage, and
also the usage effects.
[0016] To sum up, the present invention inter-dental brush
structure has a replaceable brush shaft design to adjust the angle
of the brush handle, and increase the usage effect. It is
unprecedented and possesses novelty and progress, therefore matches
the requirements for applying the new invention patent.
[0017] It will be understood that each of the elements described
above, or two or more together may also find a usefull application
in other types of methods differing from the type described
above.
[0018] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
