VIBRATION BOX ON NEGATIVE PRESSURE CUP CAPABLE OF
STRENGTHENING AIRTIGHTNESS FOR ACHIEVING WATERPROOF,
ANTI-COLLISION AND NOISE REDUCTION FUNCTIONS
BACKGROUND OF THE INVENTION
Field of Invention
The present invention belongs to a vibration box on a negative pressure cup,
and
more particularly to a vibration box on a negative pressure cup that utilizes
a
strengthened airtight structure to achieve waterproof, anti-collision and
noise reduction
functions.
Related Art
The negative pressure cup is a health care device that covers the surface of
the
body and stimulates the skin by means of negative pressure suction to achieve
the
strengthening of body; and in order to strengthen the fitness effect of the
negative
pressure cup, a vibration box can also be disposed on the negative pressure
cup to
provide vibration during the negative suction process, for promoting blood
circulation
and further strengthening the fitness effect.
In order to use it effectively for a long time, the vibration box must avoid
moisture from entering the box to cause damage, so it is necessary to
strengthen the
waterproof function; and, because the vibration box is provided with vibration
source
by a vibration motor, the vibration motor often collides with the box when it
is
operating, which not only generates noise, it also reduces the service life
and wastes
energy.

In terms of waterproof function, the common structure is an 0-shaped ring
(also
known as an 0-type ring, an 0-ring, an 0-type collar), which is a circular-
shaped
mechanical gasket, usually an elastic body, its cross section is often in
circular shape,
generally fixed in a recess, and is compressed by two or more components
during
assembly, thus creating a sealed interface.
Because of its low cost, simple manufacturing, reliable function, simple
installation requirements, and the 0-shaped ring can withstand pressure of
tens of
Pascals (thousands of pounds), the 0-shaped ring can be used in static
applications as
well as in dynamic applications where there is relative motion between
components,
such as the shaft of a rotary pump and the piston of a hydraulic cylinder.
However, due to the simple structure of the 0-shaped ring, its fixed contact
surface is usually not properly fixed, and also because of changes in the use
environment, the 0-shaped ring can easily lose its effectiveness in high
temperatures
or low temperatures, chemical corrosion, or in the process of vibration, wear
and
movement. Therefore, in addition to the selection of suitable elastomeric
materials
according to the environmental conditions, the structure needs to be further
improved.
Therefore, there is still a need for a solution to solve the above-mentioned
problem that the conventional 0-shaped rings are susceptible to variations in
the
assembly method to reduce or lose the waterproof effect.
For the functions of anti-collision and noise reduction, since the working
principle of the vibration motor is to adopt the eccentric wheel method, the
vibration
is caused by the rotation of the eccentric wheel. But the vibration motor is
not
completely tightly attached to the vibration box, and is usually fixed with a
simple
frame, and thus the frame can not effectively fix the vibration motor. The
vibration
motor itself will also sway on the frame during operation, so it is easy to
collide with

Date Recue/Date Received 2020-04-17
the vibration box. In the long run, it will damage the structure of the
vibration box and
cause damage to the product.
In addition to damaging the vibration box, arbitrary sway of the vibration
motor
will cause the vibration of the vibration box to be unstable, resulting in a
decrease in
performance and affecting the work, which will also result in waste of energy.
Moreover, operation of the vibration motor itself generates vibration noise,
plus
the sway of the vibration motor and the impact on the vibration box, the noise
generated is even more obvious and harsh, seriously affecting the user
experience.
Especially for health care work as well as in the environment for long-term
use, the
impact of noise on the user is more significant, and even the willingness to
use is
reduced, so that the function of the vibration box cannot be exerted.
In view of the aforementioned drawbacks, it is obvious that there is still
room
for improvement in the conventional technology and it needs to be solved
urgently.
With regards to this, the inventor of the present invention set about to
improve,
through long-term research and development and implementation, a vibration box
on
a negative pressure cup capable of strengthening airtightness for achieving
waterproof,
anti-collision and noise reduction functions is proposed.

in
detail below with reference to the accompanying drawings and embodiments. The
embodiments and the aspects thereof are described in detail herein, and the
description
is intended to be illustrative of the structure or the procedure steps of the
present
invention, which are provided for explanation and not used to limit the scope
of claims
of the present invention.
An embodiment described in the specification refers to particular features,
methods or characteristics described in connection with this embodiment, which
are
included in at least some embodiments. Therefore, the implementation of
various
aspects of one embodiment or various embodiments is not necessarily the same
embodiment. Furthermore, the features, methods, or characteristics of the
present
invention can be combined as appropriate in one or more embodiments.
Referring to FIG. 1 and FIG. 2, the present invention provides a vibration box
on a negative pressure cup capable of strengthening airtightness for achieving
waterproof, anti-collision and noise reduction functions, comprising a
negative
7
Date Recue/Date Received 2020-04-17
pressure cup 200 for providing a negative pressure health care function, and a
vibration
box 100 installed on the negative pressure cup 200 for providing a vibration
function.
The vibration box 100 has an accommodation space 110 therein for disposing a
vibration motor 400. A back of the vibration box 100 is disposed with a
vibration box
back cover 120, so that the vibration box back cover 120 covers the back of
the
vibration box 100 to seal the accommodation space 110.
Referring to FIG. 1 to FIG. 4A, the present invention mainly provides a
waterproof rubber element 300 which is newly applied to prevent water from
penetrating into the vibration box 100, and is applied to the waterproof
design required
for the vibration box 100. In one embodiment, the waterproof rubber element
300 is
disposed on the vibration box back cover 120 and a contact surface of the
vibration
box 100. A surface of the waterproof rubber element 300 is disposed with
recesses 310
with a concave cross section, and a shape of the recess 310 is, for example, a
U shape
or an inverse U shape. In one embodiment, the waterproof rubber element 300
can be
molded.
In one embodiment, the waterproof rubber element 300 can be made of synthetic
rubbers (also known as thermosetting polymers) such as but not limited to,
butadiene
rubber (BR), isobutylene isoprene rubber (IIR), chlorosulfonated polyethylene
rubber
(CSM, complete supplement mixture), ethylene propylene diene monomer (EPDM),
ethylene-propylene rubber (EPR), fluororubber (FKM, fluorocarbon), nitrile
butadiene
rubber (NBR), perfluoroelastomer (FFKM), polyacrylate rubber (ACR),
chloroprene
rubber (CR), polyisoprene rubber (IR), polysulfide rubber (PSR), silicone
rubber
(SIR), styrene butadiene rubber (SBR); or thermoplastics such as but not
limited to,
thermoplastic elastomers (TPE) (e.g. styrene), thermoplastic polyolefin (TPO)
(e.g.
LDPE low density polyethylene, HDPE high density polyethylene, LLDPE linear
low

Date Recue/Date Received 2020-04-17
density polyethylene, ULDPE ultra low density polyethylene), thermoplastic
polyurethane (TPU) (e.g. polyether, polyester), thermoplastic
polyester/polyether
elastomers (TEEE), thermoplastic polyamide (TPA) (e.g. polyamide), melt
processable rubber (MPR), thermoplastic vulcanizate (TPV).
The U-shaped or inverse U-shaped recess 310 of the waterproof rubber element
300 can be sleeved on a flange 130 of the vibration box back cover 120, so
that a size
and a shape of the U-shaped or inverse U-shaped recess 310 of the waterproof
rubber
element 300 need to match with a size and a shape of the flange 130 of the
vibration
box back cover 120. The waterproof rubber element 300 that is sleeved on the
flange
130 can be further disposed in a groove 140 provided on the vibration box 100
and the
contact surface of the vibration box back cover 120, so that an outer side
surface of the
waterproof rubber element 300 is in close contact with the groove 140, and the
recess
310 is sleeved on the flange 130 and embedded in the groove 140 to be
completely
sealed, thereby achieving a waterproof effect. The U-shaped or inverse U-
shaped
recess 310 of the waterproof rubber element 300 can be sleeved on the flange
130, so
that it is easier to install, not easy to displace, and not easy to fall off
in installation,
and is not susceptible to variations in the assembly method, otherwise will
reduce or
lose the waterproof effect.
Further, the waterproof rubber element 300 is a malleable elastic body made of
the foregoing materials, and when the waterproof rubber element 300 is
sandwiched
between the vibration box back cover 120 and the vibration box 100, the
waterproof
rubber element 300 is forcefully expanded to completely fit on the flanges 130
and the
grooves 140.
The flange 130 of the vibration box back cover 120 and the groove 140 of the
vibration box 100 are designed to be interchangeably disposed. Of course, a
direction

Date Recue/Date Received 2020-04-17
of the recess 310 of the waterproof rubber element 300 is adjusted to match
with
positions of the flange 130 and the groove 140.
In one embodiment, the waterproof rubber element 300 is integrally formed by
a strip surrounding the vibration box back cover 120 and the contact surface
of the
vibration box 100, with appearance like a mesh structure. Alternatively, the
waterproof
rubber element 300 can be disposed as a monolithic panel structure (not shown
in the
figures) that is capable of completely covering the back of the vibration box
100, and
the recess 310 is disposed only at a position where the panel-like waterproof
rubber
element 300 contacts the contact surface, so that the panel-like waterproof
rubber
element 300 completely covers and seals the accommodation space 110 of the
vibration box 100.
Another focus of the present invention is to provide a noise reduction cover
410
and a buffer cushion 420 for the anti-collision and noise reduction functions
of the
vibration box 100. Please refer to FIG. 1, FIG. 2, FIG. 5 and FIG. 5A. In one
embodiment, the noise reduction cover 410 is hooded outside the vibration
motor 400,
and the vibration motor 400 is fixed on the vibration box 100 by the noise
reduction
cover 410 to securely fix a position of the vibration motor 400. Therefore,
the vibration
motor 400 can be stably operated in the vibration box 100 without arbitrary
sway,
otherwise will cause the vibration motor 400 to impact on the vibration box
100, and
further, due to the cover of the noise reduction cover 410, noise generated by
the
vibration motor 400 is further reduced.
The noise reduction cover 410 has a same outer shape as that of an outer
casing
of the vibration motor 400 to securely fix the noise reduction cover 410
outside the
vibration motor 400, thereby reducing the gap and effectively preventing noise
from
being transmitted.

In one embodiment, the buffer cushion 420 is disposed between the vibration
motor 400 and the noise reduction cover 410 to ease off the sway of the
vibration motor
400 itself.
The material for the soft cushioning of the buffer cushion 420 is mainly foam,
but is not limited thereto, so as to surely exert the function of easing off
the sway of
the vibration motor 400.
In summary, the waterproof rubber element 300 of the present invention has a
special shape that matches a size and a shape of the groove 140 of the
waterproof
structure of the vibration box 100, thereby achieving the technical efficacies
of being
relatively more secure, easier to install, not easy to displace, and not easy
to fall off in
installation, and not susceptible to variations in the assembly method,
otherwise will
reduce or lose the waterproof effect. The noise reduction cover 410 and the
buffer
cushion 420 further strengthen the fixing of the vibration motor 400, so that
it is not
easy to sway during operation, reducing the possibility of the vibration motor
400
colliding with the vibration box 100, and maintaining the durability of the
product and
reducing the occurrence of noise.
While the preferred embodiments of the invention have been set forth for the
purpose of disclosure, modifications of the disclosed embodiments of the
invention as
well as other embodiments thereof may occur to those skilled in the art.
Accordingly,
the appended claims are intended to cover all embodiments which do not depart
from
the spirit and scope of the invention.
