Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an attachment device and,
more particularly, to a sucker for attaching an article to an
object, such as a wall and the like.
[0003] 2. Description of the Related Art
[0004] A conventional sucker comprises an attachment surface that
is bonded onto an object, such as a wall, plane and the like, to
attach an article to the object. However, when ambient air enters
the inside of the sucker, the negative pressure in the sucker is
reduced or released, so that the sucker is easily detached or
removed from the object, and the article easily falls down. In
addition, the user cannot predict reduction or release of the
suction force of the sucker so that the sucker is easily detached
from the object unexpectedly, thereby causing inconvenience or
danger to the user.
BRIEF SUMMARY OF THE INVENTION
[0005] In accordance with the present invention, there is provided
a sucker, comprising a sucker body, a pressure sensor connected
with the sucker body, a control circuit board connected with the
pressure sensor, and a warning member connected with the control
circuit board. The sucker body has an attachment surface. The
control circuit board and the warning member are combined with the
pressure sensor. The pressure sensor, the control circuit board and
the warning member are mounted in a closed receiving portion. The
pressure sensor is connected to the attachment surface of the
sucker body. In practice, the pressure sensor successively detects
and reacts a vacuum leak variation of the attachment surface of the
sucker body, and transmits the vacuum leak variation of the
attachment surface of the sucker body to the control circuit board.
The control circuit board converts the vacuum leak variation of the
attachment surface of the sucker body into a feedback signal, and
converts the feedback signal into an early warning signal. The
control circuit board transmits the early warning signal to the
warning member which displays or starts the early warning signal.
Thus, the sucker performs an early warning action to provide a
safety function.
[0006] The sucker further comprises a wireless transceiver
connected with the control circuit board, and a digital faceplate
connected with the control circuit board to receive a remote
wireless signal. Thus, the wireless transceiver transmits the
pressure differential from the control circuit board, and the
digital faceplate receives the remote wireless signal from the
wireless transceiver and indicates the pressure differential in the
closed receiving portion of the sucker body.
[0007] The sucker body has a periphery provided with an air hole
connected between the closed receiving portion and the attachment
surface of the sucker body to connect the closed receiving portion
to the attachment surface of the sucker body. The closed receiving
portion is directly formed in the sucker body. Alternatively, the
closed receiving portion is connected with an outer receiving
portion which is located outside of the sucker body. Thus, the
attachment surface of the sucker body is attached to an object,
with the closed receiving portion and the attachment surface of the
sucker body forming a closed chamber detection zone.
[0008] The sucker further comprises a pull-type handle or an
eccentric handle pivotally connected with the sucker body. The
handle is connected to the closed receiving portion.
[0009] The pressure sensor is directly received in the closed
receiving portion or placed in the outer receiving portion of the
sucker body.
[0010] The sucker further comprises a digital display mounted
outside of the sucker body and connected with the pressure sensor
to indicate the pressure differential in the closed receiving
portion of the sucker body.
[0011] The primary objective of the present invention is to provide
a sucker with a pressure early warning detection function.
[0012] According to the primary advantage of the present invention,
the pressure sensor, the control circuit board and the warning
member construct an early warning detection mechanism which
successively detects and monitors the pressure of the attachment
surface of the sucker body, and produces an early warning signal
automatically by detection of the pressure differential of the
attachment surface of the sucker body so as to prevent the sucker
from being detached from the object, and to provide a safety
function to the user.
[0013] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0019] Referring to the drawings and initially to FIGS. 1-3, a
sucker in accordance with the preferred embodiment of the present
invention comprises a sucker body 10, a pressure sensor 12
connected with the sucker body 10, a control circuit board 121
connected with the pressure sensor 12, and a warning member 122
connected with the control circuit board 121. The sucker body 10
has an attachment surface 11. The attachment surface 11 of the
sucker body 10 is formed on the bottom of the sucker body 10 and
has a substantially planar or concave shape. The control circuit
board 121 and the warning member 122 are combined with the pressure
sensor 12. The pressure sensor 12, the control circuit board 121
and the warning member 122 are mounted in a closed receiving
portion 13. The closed receiving portion 13 is integrally formed in
the sucker body 10. The pressure sensor 12 is connected to the
attachment surface 11 of the sucker body 10.
[0020] In practice, the pressure sensor 12 successively detects and
reacts a vacuum leak variation of the attachment surface 11 of the
sucker body 10, and transmits the vacuum leak variation of the
attachment surface 11 of the sucker body 10 to the control circuit
board 121. The control circuit board 121 converts the vacuum leak
variation of the attachment surface 11 of the sucker body 10 into a
feedback signal, and converts the feedback signal into an early
warning signal. The control circuit board 121 then transmits the
early warning signal to the warning member 122 which displays or
starts the early warning signal. Thus, the sucker performs an early
warning action to provide a safety function.
[0021] In the preferred embodiment of the present invention, the
sucker body 10 has a periphery provided with an air hole 131
connected between the closed receiving portion 13 and the
attachment surface 11 of the sucker body 10 to connect the closed
receiving portion 13 to the attachment surface 11 of the sucker
body 10. Thus, when the attachment surface 11 of the sucker body 10
is attached to an object, the closed receiving portion 13 and the
attachment surface 11 of the sucker body 10 form a closed chamber
detection zone 13A.
[0022] In operation, referring to FIGS. 2 and 3 with reference to
FIG. 1, the attachment surface 11 of the sucker body 10 is
initially attached to an object closely, to form a vacuum suction
state between the attachment surface 11 of the sucker body 10 and
the object. At this time, the closed receiving portion 13 and the
attachment surface 11 of the sucker body 10 form a closed chamber
detection zone 13A. In addition, the pressure sensor 12 is
connected to the attachment surface 11 of the sucker body 10 so
that the pressure sensor 12 can detect the pressure of the suction
force at the attachment surface 11 of the sucker body 10, and the
control circuit board 121 operates the pressure differential of the
attachment surface 11 of the sucker body 10. In such a manner, when
air permeates the attachment surface 11 of the sucker body 10 into
the closed chamber detection zone 13A, the pressure sensor 12
successively detects the pressure of the attachment surface 11 of
the sucker body 10 and transmits a pressure differential to the
control circuit board 121. Then, the control circuit board 121
compares the pressure differential of the attachment surface 11 of
the sucker body 10 with a preset pressure limit. When the pressure
differential of the attachment surface 11 of the sucker body 10
reaches the preset pressure limit, the control circuit board 121
drives the warning member 122 to emit an early warning signal to
warn a user so that the user predicts that the suction force of the
sucker body 10 is exhausted and has to supplement the vacuum
negative pressure suction force in the closed chamber detection
zone 13A so as to prevent the sucker body 10 from being detached
from the object. Thus, the sucker can monitor and detect its
pressure and can produce an early warning signal automatically by
detection of a pressure differential so as to provide a safety
function to the user.
[0023] In the preferred embodiment of the present invention, the
closed receiving portion 13 is directly formed in the sucker body
10. Alternatively, the closed receiving portion 13 is connected
with an outer receiving portion (not shown) which is located
outside of the sucker body 10 to form a closed chamber detection
zone. The pressure sensor 12 is directly received in the closed
receiving portion 13 or placed in the outer receiving portion of
the sucker body 10. The warning member 122 is an light emitting
diode (LED) light source, an audio alarm, a buzzer and the
like.
[0024] In another preferred embodiment of the present invention,
the sucker further comprises a digital display (not shown) mounted
outside of the sucker body 10 and connected with the pressure
sensor 12 to indicate the pressure differential in the closed
receiving portion 13 of the sucker body 10.
[0025] In another preferred embodiment of the present invention,
the sucker further comprises a wireless transceiver (not shown)
connected with the control circuit board 121, and a digital
faceplate (not shown) connected with the control circuit board 121
to receive a remote wireless signal. Thus, the wireless transceiver
transmits the pressure differential from the control circuit board
121, and the digital faceplate receives the remote wireless signal
from the wireless transceiver and indicates the pressure
differential in the closed receiving portion 13 of the sucker body
10.
[0026] As shown in FIG. 4, the sucker further comprises a pull-type
handle 14 pivotally connected with the sucker body 10. The handle
14 is connected to the closed receiving portion 13. Thus, when the
handle 14 is pulled outward relative to the sucker body 10, the
closed receiving portion 13 is disposed at a vacuum state so that
the attachment surface 11 of the sucker body 10 is attached to the
object by a vacuum suction force.
[0027] As shown in FIG. 5, the sucker further comprises an
eccentric handle 14 pivotally connected with the sucker body 10.
The handle 14 is connected to the closed receiving portion 13.
Thus, when the handle 14 is pulled outward relative to the sucker
body 10 in an eccentric manner, the closed receiving portion 13 is
disposed at a vacuum state so that the attachment surface 11 of the
sucker body 10 is attached to the object by a vacuum suction
force.
[0028] Accordingly, the pressure sensor 12, the control circuit
board 121 and the warning member 122 construct an early warning
detection mechanism which successively detects and monitors the
pressure of the attachment surface 11 of the sucker body 10, and
produces an early warning signal automatically by detection of the
pressure differential of the attachment surface 11 of the sucker
body 10 so as to prevent the sucker from being detached from the
object, and to provide a safety function to the user.
[0029] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
