ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a massage device, and especially to a massage device having a firmly secured combining structure and an improved massage effect.
BACKGROUND OF THE INVENTION
Referring to
FIG. 1
, the prior massage device
1
a
includes a holdable rod
10
a
. The distal end of the rod
10
a
is installed to the top surface of the housing
11
a
. The bottom of the housing
11
a
is installed with a hollow recess
12
a
. The outer edge of the recess
12
a
is formed with an annular gluing portion
13
a
. The inner lateral side of the gluing portion
13
a
near the recess
12
a
is stuck to an outer edge of an elastomer
14
a
by glue (not shown) so that the elastomer
14
a
may protrude out and adhere to the bottom of the housing
1
a
. A plurality of spaced arranged apertures
15
a
are installed on the elastomer
14
a
. Each aperture
15
a
is installed with a protrusion
16
a
. The protrusion
16
a
allows the massage device
1
a
to have the effect of a massage.
However, since the elastomer
14
a
is only stuck to the inner surface of gluing portion
13
a
by glue (not shown) and after prolonged use, the outer edge of the elastomer
14
a
is easily separated from the gluing portion
13
a
due to a press force, and thus, loosening the structure. Moreover, in manufacturing the massage device, the elastomer
14
a
and the gluing portion
13
a
are combined by surface contact and excess glue (not shown) may flow out so as to affect the outlook of the product. Furthermore, a poor massage effect may occur since the elastomer
14
a
and the glue
13
a
are combined.
SUMMARY OF THE INVENTION
Accordingly, the primary objective of the present invention is to provide a massage device with a tight structure. The elastomer will not separate from the housing over prolonged use. Moreover, glue will not flow from the device so as to sustain a beautiful appearance.
Another objective of the present invention is to provide a massage device with an elastomer having a stronger structure for a preferred massage effect.
A further objective of the present invention is to provide a massage device which can be assembled easily and conveniently so that the products can be diversified and produced rapidly.
To achieve the aforesaid objectives, the present invention provides a massage device including a housing, a connecting unit and an elastomer. The bottom of the housing is installed with an inner wall. The inner wall of the housing corresponds to the outer wall of the connecting unit to coupled the connecting unit to the housing. Furthermore, the inner wall of the connecting unit is installed with a trench, and a plurality of through holes. The through holes communicate with the trench. The outer edge of the elastomer is installed in the trench of the connecting unit in order for the elastomer to protrude from the bottom of the housing. Glue fills the through holes so as to achieve a better combination.
The present invention also provides a massage device, wherein the trench of the connecting unit is formed with an opening. A bending portion is installed at the opening near the inner wall of the connecting unit, and the bending portion is inwardly reduced so that the bottom of the inner wall of the connecting unit is bent inwards. This gives the elastomer a stronger structure so as to present a preferred massage effect.
The present invention provides a massage device, wherein the bottom of the housing has a hollow recess. The inner wall of the recess is formed with an annular groove. An annular tilt surface is installed on the outer wall of the connecting unit. The tile surface will cause the outer edge of the groove to enlarge gradually along the tilted surface of the connecting unit as the housing and the connecting unit are engaged until the connecting unit is buckled. Therefore, the connecting unit and the housing can be rapidly and conveniently buckled so that the product can be produced rapidly.
