Wireless auto flusher
Abstract
The present invention is to provide a wireless auto flusher,
including a small-sized water power generator mounted between the
water inlet and the water outlet of the auto flusher. The water
flow may drive the small-sized water power generator to charge the
charging battery through the steady pressure of the steady pressure
charging circuit, there providing an electric power to the
controller without power supply, so as to sense or receive and
transmit a signal to the pulse electromagnetic valve, such that the
pulse electromagnetic valve may act and operate, thereby saving
energy.

Claims
What is claimed is:
1. A wireless auto flusher, comprising: a water inlet, a water
outlet, a sensor, a controller, a pulse electromagnetic valve, a
small-sized water power generator, a steady pressure charging
circuit, and a charging battery; wherein, when the sensor receives
a detection signal from a human body, the controller informs and
opens the pulse electromagnetic valve, such that water flow passes
through the water inlet to flush; the water flow passes through the
small-sized water power generator before the water flow passes
through the water outlet; the water flow is driven by the
small-sized water power generator, to charge the charging battery
through the steady pressure of the steady pressure charging
circuit, there providing an electric power to the controller, so as
to sense or receive and transmit a signal to the pulse
electromagnetic valve, so that the pulse electromagnetic valve may
act and operate.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a wireless auto flusher,
and more particularly to a wireless auto flusher which uses the
flushing water flow to drive the small-sized water power generator
to charge the charging battery, there providing an electric power
to the controller so as to control operation of the pulse
electromagnetic valve.
[0003] 2. Description of the Related Art
[0004] A conventional auto flusher in accordance with the prior art
comprises an electromagnetic valve set and a sensor. The sensor
that is connected with the electric power may detect if a human
body is approaching, and may then energize the electromagnetic
valve set which drives the magnetic rod to lift or lower, so as to
open or close the water source. However, the conventional auto
flusher needs an additional connecting cord connected to the power
supply or needs a battery so as to provide electric power to the
electromagnetic valve set, thereby consuming the electric power or
the battery, and thereby causing waste of energy.
SUMMARY OF THE INVENTION
[0005] The present invention has arisen to mitigate and/or obviate
the disadvantage of the conventional auto flusher.
[0006] The primary objective of the present invention is to provide
a wireless auto flusher, including a small-sized water power
generator mounted between the water inlet and the water outlet of
the auto flusher. Thus, when the sensor receives a detection signal
from a human body, the controller informs and opens the pulse
electromagnetic valve, such that water flow passes through the
water inlet to provide a flushing function. At the same time, the
water flow may drive the small-sized water power generator to
charge the charging battery through the steady pressure of the
steady pressure charging circuit, there providing an electric power
to the controller without power supply, to sense or receive and
transmit a signal to the pulse electromagnetic valve, such that the
pulse electromagnetic valve may act and operate, thereby saving
energy.
[0007] Another objective of the present invention is to provide a
wireless auto flusher without needing connection with an external
power supply. The wireless auto flusher may charge the charging
battery by the small-sized water power generator, thereby providing
a power supply automatically, thereby saving energy.
[0008] In accordance with the present invention, there is provided
a wireless auto flusher, comprising: a water inlet, a water outlet,
a sensor, a controller, a pulse electromagnetic valve, a
small-sized water power generator, a steady pressure charging
circuit, and a charging battery; wherein, when the sensor receives
a detection signal from a human body, the controller informs and
opens the pulse electromagnetic valve, such that water flow passes
through the water inlet to flush; the water flow passes through the
small-sized water power generator before the water flow passes
through the water outlet; the water flow is driven by the
small-sized water power generator, to charge the charging battery
through the steady pressure of the steady pressure charging
circuit, there providing an electric power to the controller, so as
to sense or receive and transmit a signal to the pulse
electromagnetic valve, so that the pulse electromagnetic valve may
act and operate.
[0009] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is a block view of a wireless auto flusher in
accordance with a preferred embodiment of the present
invention.
DETAILED DESCRIPTION OF THE INVENTION
[0011] Referring to FIG. 1, a wireless auto flusher in accordance
with the preferred embodiment of the present invention comprises a
water inlet 10, a water outlet 20, a sensor 1, a controller 2, a
pulse electromagnetic valve 3, a small-sized water power generator
4, a steady pressure charging circuit 5, and a charging battery 6,
thereby forming an automatic flushing device without power
supply.
[0012] When the sensor 1 receives a detection signal from the human
body, the controller 2 informs and opens (ON) the pulse
electromagnetic valve 3, so that water in the pipe flows downward
through the water inlet 10 to flush.
[0013] The water flow will pass through the small-sized water power
generator 4 before the water flow passes through the water outlet
20. The water flow is driven by the small-sized water power
generator 4, and is acted by the steady pressure of the steady
pressure charging circuit 5, to charge the charging battery 6,
there providing the electric power to the controller 2, so as to
sense or receive and transmit the signal to the pulse
electromagnetic valve 3, so that the pulse electromagnetic valve 3
may act and operate.
[0014] The operation of the present invention is described as
follows.
[0015] 1. When the sensor 1 detects the existence of the human
body, the controller 2 will send a signal to open (ON) the pulse
electromagnetic valve 3, so that water in the pipe may flow
downward to flush for four seconds. Then, the controller 2 sends a
signal to close (OFF) the pulse electromagnetic valve 3 which is
then returned to the stand-by state.
[0016] 2. When the human body leaves the auto flusher, the
controller 2 will send a signal to open (ON) the pulse
electromagnetic valve 3, so that water in the pipe may flow
downward to flush for seven seconds. Then, the controller 2 sends a
signal to close (OFF) the pulse electromagnetic valve 3 which is
then returned to the stand-by state.
[0017] 3. After the human body leaves the auto flusher, if the
controller 2 again receives the signal in twenty seconds, the auto
flusher of the present invention only returns to the state of the
above-mentioned second step (omits the above-mentioned first step).
That is, the controller 2 will send a signal to open (ON) the pulse
electromagnetic valve 3, so that water in the pipe may flow
downward to flush for seven seconds. Then, the controller 2 sends a
signal to close (OFF) the pulse electromagnetic valve 3 which is
then returned to the stand-by state, thereby preventing from
consumption of water, and thereby saving the cost.
[0018] Accordingly, the wireless auto flusher of the present
invention may construct an automatic flushing device that may
generate electric power and charge automatically without power
supply, thereby greatly saving energy. In addition, it is
unnecessary to replace and waste the battery, thereby preventing
from causing environmental pollution.
[0019] Although the invention has been explained in relation to its
preferred embodiment 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.
