Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a massage brush, and
particularly relates to a massage brush with a tightly engaged
massage structure to prevent the massage structure from being
removed from the massage brush.
[0003] 2. Background of the Invention
[0004] Referring to FIG. 1, a conventional massage brush 1a
includes a massage structure 11a, a circle pad 12a engaged with the
massage structure 11a and an exterior cover 13a clamping the pad
ring 12a. The massage structure 11a has a U-shaped fastening
portion 111a made integrally in one piece and clipping a flange
portion 121a of the circle pad 12a for the circle pad 12a to be
received therein. The circle pad 12a has a circular recess 122a
formed in a bottom thereof, and the exterior cover 13a has a
circular protrusion 131a arranged integrally in one piece thereon
and relating to the circular recess 122a for the circular
protrusion 131a engaging in the circular recess 122a. The
conventional massage brush 1a further includes a back paste 14a
filled between the circular protrusion 131a and the circular recess
122a for a tight engagement therebetween.
[0005] However, the U-shaped fastening portion 111a of the
conventional massage brush 1a becomes fatigued after long-term use
and there is no retaining device or structure securing the U-shaped
fastening portion 111a, so the U-shaped fastening portion 111a will
be removed easily and the conventional massage brush 1a will become
useless.
[0006] The conventional massage brush 1a connects the circular
protrusion 131a in the circular recess 122a via the back paste 14a,
and accordingly match problems must be considered between the
circle pad 12a and the back paste 14a, or between the exterior
cover 13a and the back paste 14a (which has a material interaction
therebetween). Usually, the circle pad 12a and the exterior cover
13a are made of PMMA (polymethylmethacrylate) materials. The PMMA
materials are usually more expensive than other polymers, such as
PP (polypropylene), PVC (polyvinyl chloride), and the like. But
these other materials cannot be substituted for the PMMA because of
the back paste 14a and match problems there between, and that keeps
the cost high.
[0007] In addition, the back paste 14a filled therein may be
improper and overfilled, and the PMMA is a transparent material, so
that the overfilled back paste 14a will be seen and negatively
affect its attractiveness to purchasers.
[0008] Furthermore, the back paste 14a filled therein will connect
the circle pad 12a to the exterior cover 13a so tightly that
changing the massage structure 11a of the conventional massage
brush 1a is impossible. When the massage structure 11a wears out,
the conventional massage brush 1a is useless. If the circle pad 12a
or the exterior cover 13a breaks from incorrect use, the first
conventional massage brush 1a is also useless.
[0009] Hence, an improvement over the prior art is required to
overcome the disadvantages thereof.
SUMMARY OF INVENTION
[0010] The primary object of the invention is therefore to specify
a tightly engaged massage brush to prevent a massage structure
thereof from being removed therefrom. The secondary object of the
invention is therefore to specify an easily assembled and detached
massage brush, the elements of which can be changed.
[0011] The third object of the invention is therefore to specify a
massage brush that can be made of other polymer materials to reduce
costs.
[0012] The fourth object of the invention is therefore to specify a
massage brush that omits the back paste, so that design and
material match problems need not be considered, and the
manufacturing efficiency thereof is improved.
[0013] The fifth object of the invention is therefore to specify a
massage brush with an appearance improved by omitting the back
paste, thereby increasing the attractiveness thereof to
purchasers.
[0014] According to the invention, this object is achieved by a
massage brush including a massage structure, an orientation ring
engaging tightly with the massage structure, a circular pad
received in the massage structure, and an exterior cover retained
against the circular pad and the orientation ring. The circular pad
includes a flange disposed therearround and clamped in the massage
structure, and an L-shaped restriction portion extending downwardly
from a bottom thereof to support the orientation ring thereon. The
orientation ring engages with the massage structure, the L-shaped
restriction portion, and the exterior cover simultaneously for
tightly clamping the massage structure therewith.
[0015] To provide a further understanding of the invention, the
following detailed description illustrates embodiments and examples
of the invention. Examples of the more important features of the
invention thus have been summarized rather broadly in order that
the detailed description thereof that follows may be better
understood, and in order that the contributions to the art may be

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] With respect to FIG. 2 and FIG. 4, a first embodiment of a
massage brush 2 according to the present invention is described.
The massage brush 2 includes a massage structure 21, an orientation
ring 24 engaged tightly with the massage structure 21, a circular
pad 22 received in the massage structure 21, and an exterior cover
23 retained against the circular pad 22 and the orientation ring
24. The massage structure 21 has a U-shaped fastening portion 211
arranged circularly inwards and made integrally in one piece. The
circular pad 22 includes a flange 221 disposed therearround and an
L-shaped restriction portion 222 extends downwardly from a bottom
of the circular pad 22, the flange 221 clamps in the U-shaped
fastening portion 211 of the massage structure 21, the L-shaped
restriction portion 222 is formed by drawing back a predetermined
distance "d" from the flange 221 to receive the U-shaped fastening
portion 211 and support the orientation ring 24 thereon. The
exterior cover 23 further includes a step portion 231 arranged on
an inner side thereof for retention against the L-shaped
restriction portion 222. The exterior cover 23 is retained against
the massage structure 21, the orientation ring 24 and the L-shaped
restriction portion 222 simultaneously to secure the massage
structure 21 to the exterior cover 23.
[0024] Comparing with the conventional massage brush 1a, the
U-shaped fastening portion 111a is clamped with the circle pad 12a
and the exterior pad 13a. In the present invention, the orientation
ring 24 is tightly engaged with the U-shaped fastening portion 211.
The flange 221 and the L-shaped restriction portion 222 of the
circular pad 22 together provide a vertical clamping force in an
upper-to-lower direction. The flange 221 of the circular pad 22 and
the orientation ring 24 together provide a horizontal clamping
force in a right-to-left direction. The massage structure 21 is
thus prevented from removing therefrom.
[0025] The orientation ring 24 has a clamping portion 241
circularly protruding from an outer circumstance thereof and a
restriction surface 242 protruding from an inner top thereof to
engage with the U-shaped fastening portion 211. The clamping
portion 241 shrinks from a top to a bottom thereof, and includes a
smooth surface for assembling easily. The exterior cover 23 has a
clamping groove 232 formed thereon and relating to the clamping
portion 241 of the orientation ring 24, so that the orientation
ring 24 engages with the exterior cover 23 tightly.
[0026] Furthermore, corresponding to the conventional massage brush
1a, the present invention omits the back paste 14a, so that design
and material match problems due to the back paste 14a will never be
considered. The orientation ring 24, the circular pad 22 and the
exterior cover 23 will not be restricted by made of the PMMA, thus
the process and manufacturing steps will be simplified. The
orientation ring 24, the circular pad 22 and the exterior cover 23
may be made of PP (Polypropylene) or PVC (Polyvinyl Chloride)
alternatively to reduce costs. The prevent invention avoids
destroying the appearance thereof without the back paste 14a, and
users' purchasing wills accordingly will be inspired.
[0027] The present invention provides the massage structure 21, the
orientation ring 24, the circular pad 22 and the exterior cover 23
together assembled into the massage brush 2. The present invention
omits the back paste 14a, which is used as a glue and is permanent,
and provides a massage brush 2 that is easily assembled or
detachable for changing elements thereof.
[0028] Referring to FIGS. 2 and 4, the exterior cover 23 includes a
long handle 233 for manipulating. With respect to FIG. 5, a second
embodiment of the massage brush 2, the exterior cover 23 includes a
pinch portion 234 extended from a top thereof. The pinch portion
234 has a curve body 2341 shaped ergonomically and a head 2342
connecting the curve body 2341, whereby the head 2342 is bigger
than the curve body 2341. A user holds the curve body 2341 with the
fingers and retains the head 2342 by the back of the hands.
[0029] In FIG. 6, in a third embodiment of the massage brush 2, the
pinch portion 234 is disposed on an end of the top of the exterior
cover 23, and the head 2342 has a retention member 2343 extending
forward from an opposite end thereof. The user clamps the curve
body 2341 with the fingers and retains the head 2342 and the
retention member 2343 by back of the hands.
[0030] The massage brush 2 includes the massage structure 21, the
orientation ring 24 engaged tightly with the massage structure 21,
the circular pad 22 received in the massage structure 21, and the
exterior cover 23 retained against the circular pad 22 and the
orientation ring 24. The flange 221 and the L-shaped restriction
portion 222 of the circular pad 22 together provide the vertical
clamping force in the upper-to-lower direction, and the flange 221
of the circular pad 22 and the orientation ring 24 together provide
the horizontal clamping force in the right-to-left direction, for
preventing the massage structure 21 from being removed therefrom
during use.
[0031] It should be apparent to those skilled in the art that the
above description is only illustrative of specific embodiments and
examples of the invention. The invention should therefore cover
various modifications and variations made to the herein-described
structure and operations of the invention, provided they fall
