Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a complex type toothbrush
and, particularly, to a toothbrush provided with a rotary brush
head in addition to a conventional fixed type brush head.
[0003] 2. Description of Related Art
[0004] It is known that the oral cavity hygiene influences our body
health very much. In fact, it is absolutely advantageous for us to
eat food or take nutrition. Contrarily, incomplete teeth or ill
teeth are hard for us to eat different kinds of food smoothly.
[0005] Good teeth are essentially from health care and especially
it is necessary to have a good habit of teeth brushing. It is
realized that the traditional toothbrush has fixed brush head,
i.e., the part with brush hairs and the user has to move the
toothbrush up and down in order to clean the food residue or the
tartar staining on the teeth. However, the food residue left in
slits between teeth is incapable removed with the traditional
toothbrush. Hence, a good and effective toothbrush is much helpful
for cleaning the food residue staying between teeth in addition to
a good habit of teeth brushing.
[0006] According, electric toothbrush was developed to overcome the
preceding shortcoming but an ordinary electric toothbrush needs
electric power and motor with eccentric device so that it becomes
heavy and large. In addition, the electric toothbrush is more
expensive and it is necessary to be charge in case of power
exhaust. Hence, it is not so perfect as we expect.
SUMMARY OF THE INVENTION
[0007] The crux of the present invention is to provide a complex
type toothbrush, which includes a push handle, a base, a brush seat
and a rotary brush part. The push handle provides a brush handle
part joining a push stem with an elongated push groove at the push
stem. The base is surrounded with a base edge to form an open top
base chamber and is provides a base hole. The brush seat at both
ends thereof has a hair seat respectively with each hair seat being
attached with brush hairs and at the middle thereof has a circular
seat recess with a central brush hole. The rotary brush part
provides a rotary brush head with brush hairs at the seat recess
and being joined to the push stem for being rotated in a right
direction or a reversed direction about an axis of the base hole
during the push stem being moved forward or backward.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The present invention can be more fully understood by
reference to the following description and accompanying drawings,

[0009] FIG. 1 is an exploded perspective view of a complex type
toothbrush according to a preferred embodiment of the present
invention;
[0010] FIG. 2 is a perspective view of the complex type toothbrush
shown in FIG. 1;
[0011] FIG. 3 is a sectional view of the complex type toothbrush
shown in FIG. 2;
[0012] FIG. 4 is an exploded perspective view of a complex type
toothbrush according to another preferred embodiment of the present
invention; and
[0013] FIG. 5 is a sectional view of the complex type toothbrush
shown in FIG. 4.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIGS. 1 and 2, a complex type toothbrush of the
present invention includes a push handle 1, a base 2, a brush seat
3 and a rotational brush part 4.
[0015] Wherein, the push handle 1 has a brush handle part 11 and a
push stem 12 connected to the front end of the brush handle 11. The
push stem 12 can be made integrally with the brush handle 11 can
engage with the brush handle part 11 by way of holes fitting with
tenons as shown in FIG. 1. Because these are conventional art so
that no detail will be described further. The push stem 12 at the
front end thereof is provided with an elongated push groove 121 and
a side recess 122 as shown in FIG. 1. The push stem 12 is flat so
as to be received in the base 2.
[0016] The base 2 has a base bottom 21 and a base edge 22 extending
vertically surrounding the base 2 to form a semi-closed space and
constitute a base chamber 23 so that the push stem 12 can be
received in the base chamber 23. Therefore, a base recess 24 is
provided at an end of the base 2 facing the front end of the brush
handle 11. In the mean time, the base 2 at both lateral sides
thereof has a baffle 25 respectively. Besides, the base bottom 21
at the central area thereof can hunch up to form a base ridge 26
with a blind base hole 27 (not shown because of the projection
angle).
[0017] The brush seat 3 is solid provides a size corresponding to
the base chamber 23 so that the brush seat 3 can be received in the
base chamber 23. The brush seat 3 at both ends thereof has a hair
seat 31 respectively and the hair seat 31 is attached with multiple
brush hairs 32 and at the middle thereof has a right downward
circular seat recess 33 with a central brush hole 34. In order to
fit with the base 2, the hair seats 31 at the outer wall thereof
has a reduced insert part 35.
[0018] The rotational brush part 4 is composed of a rotary brush
head 41 and a rotary rod 42. The rotary brush head 41 further is
composed of a conventional base body and brush hairs. The base body
at the bottom thereof has a central fitting hole 411 (not shown
because of the projection angle) and the rotary rod 42 has a crank
head 421 extending outward to pierce the fitting hole 411 and a
crank arm 422, which is at an end of the crank head 421, is
perpendicular to the crank head 421. The crank arm 422 has a size
corresponding to the side recess 122 so as to be inserted in the
side recess 122. Further, the end next to the crank arm 422 extends
a crank core 423 so as be inserted into the brush hole 34.
[0019] Referring to FIG. 2 again, the push stem 12 of the push
handle 1 is inserted into the base chamber 23 from the base recess
24 during the complex type toothbrush of the present invention
being assembled. The crank core 423 of the rotary crank 42 passes
through the push groove 121 and the crank arm 422 is inserted into
the side recess 122. The brush seat 3 is fixedly attached to the
base 2 and the crank head 421 passes through the brush hole 34 and
is inserted into the fitting hole 411 of the rotary brush head 41.
Hence, the parts of the toothbrush can be assembled completely as
shown in FIG. 2.
[0020] Referring to FIG. 3, it can be seen from the sectional view
that friction or resistance between the brush hairs and teeth of a
user can be produced while the toothbrush of the present invention
is used. Thus, the moving forward or backward push force actuates
the push stem 12 to move forward. Right at the moment, the push
groove 121 rotates the rotary crank 42 and allows the push stem 12
to move forward so as to rotate the rotary brush head 41 and vice
versa. In this way, the toothbrush of the present invention can be
performed with a hand and the brush hairs can be fixed in place
through mechanical transmission design. In addition, the rotary
brush hairs are provided to secure the motion of toothbrush and
enhance the function thereof.
[0021] Referring to FIGS. 4 and 5, another embodiment of the
present invention is illustrated. It can be seen that a gear set is
adopted and the side recess 122 provided in the previous embodiment
is not used. An elongated opening with two circular ends and a
section of rack 123 being at the side wall of the opening is
provided and a gear 424 is mounted to mesh with the rack instead of
the crank arm 422. In this way, the same effect as the previous
embodiment can be obtained as well.
[0022] It is appreciated that the complex type toothbrush of the
present invention has a rotary brush part 4, which can rotate with
respect to the push handle being moved, in addition to the
conventional hand moved brush hair part. Hence, dual functions can
be performed effectively and it is incapable of being done by the
conventional toothbrush.
[0023] While the invention has been described with reference to
preferred embodiments thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
