toothbrush head and a handle. The toothbrush head connects to the
handle directly. Multiple bristles are mounted on the toothbrush
head. Users can pick up the handle and put the toothbrush head into
the mouth to clean their oral cavities. Tooth, gaps between the
teeth, and gingiva may be cleaned by the multiple bristles on the
toothbrush head.
[0003] Moisture may remain on the bristles after tooth cleaning.
The conventional manual toothbrush comprises cavities to receive
the bristles on the toothbrush head. Other portions of the
conventional manual toothbrush are solid. The moisture on the
toothbrush head is hard to remove. Furthermore, the bristles
mounted on the center of the toothbrush head are prone to bacteria
breeding due to the remaining moisture.
[0004] In addition, food residues easily remain in the gaps between
the multiple bristles during tooth cleaning. The food residues are
hard to remove by rinsing, thus also inducing the bacteria
breeding.
SUMMARY OF THE INVENTION
[0005] An objective of the present invention is to provide a
toothbrush head that comprises multiple through holes. The multiple
through holes are defined through a top surface and a bottom
surface of the toothbrush head. Water drops and food residues on
the toothbrush head may be easily removed through the multiple
through holes. Air convection may also be induced around the
toothbrush head by the multiple through holes. Then the toothbrush
head and the bristles mounted on the toothbrush head are dried
quickly, effectively reducing bacteria breeding on the toothbrush
head.
[0006] To achieve the foregoing objective, the present invention of
a toothbrush head comprises: a body, multiple cavities, and
multiple through holes.
[0007] The body is an elongated bar. The body further comprises a
top surface and a bottom surface.
[0008] The multiple cavities are recessed into the top surface at
spaced intervals. The multiple cavities disconnect from one
another. In addition, the multiple bristle units are respectively
mounted in the multiple cavities.
[0009] The multiple through holes are formed on the body at spaced
intervals. The multiple through holes are defined through the top
surface and the bottom surface directly. Each of the multiple
through holes is encompassed by the multiple cavities.
[0010] Preferably, the multiple cavities and the multiple through
holes disconnect from one another.
[0011] According to the above described, the multiple through holes
are adjacent to the multiple bristle units mounted in the multiple
cavities. Moisture on the top surface may be removed through the
multiple through holes. Air convection may also be induced around
the toothbrush head by the multiple through holes. The drying speed
of the toothbrush head may be raised. Bacterias and viruses can
hardly survive on the dry toothbrush head. Users also can remove
residues between the multiple bristles through the multiple through
holes by sharp objects.

the multiple cavities 11. The multiple cavities 11 are adjacent the
multiple through holes 12 but disconnect from the multiple through
holes 12.
[0021] The rubber layer 13 covers the bottom surface 102. The
rubber layer 13 comprises multiple through apertures 131. The
multiple through apertures 131 are corresponding to the multiple
through holes 12 in position and shape. A diameter of each the
multiple through apertures 131 is larger than or equal to a
diameter of each the multiple through holes 12.
[0022] With reference to FIG. 4, the rubber layer 13 comprises a
lower surface 130 away from the body 10. Multiple protrusions 132
are mounted on the lower surface 130 at spaced intervals. The
multiple protrusions 132 are spherical or hemispherical. A number
of the multiple protrusions 132 is larger than a number of the
multiple through apertures 131. The multiple through apertures 131
are encompassed by the multiple protrusions 132. The rubber layer
13 and the multiple protrusions 132 are integrally formed into one
piece. The rubber layer 13 and the multiple protrusions 132 are
made of soft rubber or soft plastic. The rubber layer 13 is mounted
on the bottom surface 102 by an adhesive or injection molding
process.
[0023] With reference to FIGS. 5 and 6, the second embodiment of
the toothbrush head in accordance with the present invention also
comprises: a body 20, multiple cavities 21, multiple through holes
22, and a rubber layer 23. The body 20 also comprises a top surface
201 and a bottom surface 202. Multiple bristle units 24 are mounted
in the multiple cavities 21 respectively. The differences between
the first and second embodiments of the toothbrush head are
described as follows:
[0024] The multiple cavities 21 are defined through the body 20
from the top surface 201 toward the bottom surface 202; and
[0025] a number of the multiple cavities 21 is less than a number
of the multiple through holes 22, and each of the multiple cavities
21 is encompassed by the multiple through holes 22.
[0026] The rubber layer 23 covers the bottom surface 202. The
rubber layer 23 comprises multiple through apertures 231. The
multiple through apertures 231 are corresponding to the multiple
through holes 22 in position and shape. The multiple through
apertures 231 connect to the multiple through holes 22.
[0027] The rubber layer 23 further comprises a lower surface 230
away from the body 20. Multiple protrusions 232 are formed on the
lower surface 230 at spaced intervals. The rubber layer 23 and the
multiple protrusions 232 are integrally formed into one piece. The
multiple protrusions 232 are spherical. A number of the multiple
protrusions 232 is less than a number of the multiple through
apertures 231. Each of the multiple protrusions 232 is encompassed
by the multiple through apertures 231.
[0028] In the above embodiments of the toothbrush head, the
multiple through holes 12, 22 are adjacent to the multiple cavities
11, 21 fixed with the multiple bristle units 14, 24. Moisture on
the multiple bristle units 14, 24 may be removed from the top
surface 101, 201 to the bottom surface 102, 202 of the body 10, 20.
It is effective to prevent moisture remaining on the top surface
101, 201 of the body 10, 20. The multiple through holes 12, 22 may
increase the air convection around the toothbrush head. The
multiple bristle units 14, 24 may be dried fast.
[0029] Furthermore, food residues may be removed through the
multiple through holes 12, 22 from the multiple bristle units 14,
24 by rinsing the top surface 101, 201 of the body 10, 20. If the
food residues are too large to be removed through the multiple
through holes 12, 22, users can insert toothpicks into the multiple
through holes 12, 22 from the bottom surface 102, 202 of the body
10, 20 to push the food residues away from the top surface 101,
201. It is effective to avoid bacteria breeding on the toothbrush
head.
[0030] The body 10, 20 of the toothbrush head is usually made of
hard materials. When a user uses the toothbrush head to clean the
oral cavity, the friction and the collision between the body 10, 20
and the oral membrane may be caused, inducing discomfort of the
user. The present invention utilizes the rubber layer 13, 23 to be
a buffer material between the body 10, 20 and the oral membrane,
thereby effectively reducing the direct friction and collision
between the body 10, 20 and the oral membrane. Furthermore, the
multiple protrusions 132, 232 on the rubber layer 13, 23 may
massage the gingival or tongue in the oral cavity.
[0031] In summary, the present invention mainly utilizes the
multiple through holes 12, 22 defined through the top surface 101,
201 and the bottom surface 102, 202 of the body 10, 20. The
multiple through holes 12, 22 provide channels to eliminate the
moisture on the toothbrush head. It is effective to reduce the
moisture remaining on the toothbrush head. In addition, the air
convection is increased around the toothbrush head by the multiple
through holes 12, 22. The bristle mounted on the body 10, 20 may be
dried quickly, effectively avoiding bacteria breeding on the
toothbrush head and inducing oral infection.
[0032] The present invention also utilizes the rubber layer 13, 23
as a buffer material. The rubber layer 13, 23 may reduce the
friction and collision between the body 10, 20 and the oral
membrane during use of the toothbrush. The rubber layer 13, 23 may
also provide other functions such as massaging for the gingival or
tongue. The present invention of the toothbrush head provides safe,
sanitary, and comfortable experience for users.
