Water filter description
FIELD OF THE INVENTION
[0001] The present invention relates to water filter devices, and
particular to a filter core controller device of a water filter
device which can determine the accumulating operation time period
and to determine whether the filter core is manufactured by the
original manufacturer.
BACKGROUND OF THE INVENTION
[0002] Water filter devices are currently widely used in homes
or offices so as to filter impurities from the water to assure the
cleanness of the water. However, the filter core will be ineffective
as it is used overdue. To assure the water filter device is used
in a due time, the service period of the filter core is recorded.
[0003] The prior art water filter device mainly includes a filter
core and a control device. The filter core has a sensor to sense
the operation of the filter core and then the operation time is
transferred to the control device. Operation time is accumulated
to calculate the accumulating operation time of the filter core.
However, in this prior art, if the original filter core is overdue,
the user places another filter core to replace the original one,
but it is possible that the update filter core has been used and
possible that the update filter core is not the one manufactured
by another manufacturer. Maybe the filter core is a counterfeit
one which has bad quality.
[0004] Thereby, there is an eager demand for a novel filter core
which can be detected so as to determine the accumulating operation
time period and to determine whether the filter core is manufactured
by the original manufacturer.
SUMMARY OF THE INVENTION
[0005] Accordingly, the primary object of the present invention
is to provide a filter core controller device of a water filter
device which can determine the accumulating operation time period
and to determine whether the filter core is manufactured by the
original manufacturer.
[0006] To achieve above objects, the present invention provides
a filter core controller device of a water filter device which comprises
a chip in a filter core of the water filter device; the filter core
having an erasable chip; codes and accumulating operation time period
being recorded in the chip; a control unit for reading the cord
in the chip so as to determining whether the filter core is a set
one and reading the accumulating operation time period for determining
whether the filter core is overdue and updating the accumulating
operation time period in the chip. The signals of the chip and the
signals of the control device are transmitted wirelessly or by wires.
[0007] Moreover, the present invention provides a filter core controller
device of a water filter device. The controller device comprises
a control device for controlling operation of the water filter device;
a display device for displaying an accumulating operation time period
and a current operation time; a detecting device for detecting actuations
and de-actuations of the water filter device; a filter core; a chip
in the filter core for recording a password and an accumulating
operation time period of the filter core; a timer for measuring
a current operation time which is then transfereed to the control
device and the chip of the filter core to be added to the accumulating
operation time period. When the filter core is installed in the
water filter device; the control device will read the password in
the chip for determining whether the filter core is a set one. If
yes, the filter core is actuated, otherwise the filter core is stopped;
if the filter core is a set one, then the control device determines
whether the filter core is overdue from the accumulating operation
time period read from the chip.
[0008] The various objects and advantages of the present invention
will be more readily understood from the following detailed description
when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION
[0013] In order that those skilled in the art can further understand
the present invention, a description will be described in the following
in details. However, these descriptions and the appended drawings
are only used to cause those skilled in the art to understand the
objects, features, and characteristics of the present invention,
but not to be used to confine the scope and spirit of the present
invention defined in the appended claims.
[0014] With reference to FIGS. 1 and 2 the filter core controller
device of a water filter device of the present invention is illustrated.
The water filter device has a control unit 21 for controlling the
operation of the whole water filter device, a display device 22
for displaying the accumulating operation time period and the operation
time of the water filter device; a detecting device 23 for sensing
the actuation and stop of the water filter device; and a timer 25
for measuring the operation of the filter core.
[0015] The filter core 1 has a chip 11 and a joint 24. The joint
24 serves to transfer signals to the control unit 21.
[0016] The filter core 1 is has the erasable chip 11 with memory
function. The chip 11 of the filter core 1 records a specific password
31 and the accumulating operation time period 12 of the filter core
1. The operation time measured by the timer 25 is transferred to
the control unit 21 and the chip 11 and the chip 11 adds the operation
time to the accumulating operation time period 12.
[0017] When the filter core 1 is filled intlo the water filter
device, chip 11 of the filter core 1 will communicate to the joint
24. Meanwhile, when filter core 1 is installed into the water filter
device. The control unit 21 of the water filter device will read
the password 31 in the chip 11 and check whether the password 31
is matched to set data in the control unit 21 so as to determine
whether the filter core 1 is a set one. If yes, the filtering function
of the filter core 1 is actuated. Otherwise, the water filter device
is stopped so as to achieve the object of counterfeit-proof.
[0018] If the filter core 1 is a set one, the control unit 21 will
further read the accumulating operation time period 12 in the chip
11 to determine whether the filter core 1 is used or to determine
the operation time of the filter core 1 so as to determine whether
the filter core 1 is in the usable period. If not, the filter core
1 is not actuated. If yes, the filter core 1 is actuated so as
to filter water flowing through the water filter device. Meanwhile,
the timer 25 calculates the operation time and input the operation
time into the control unit 21. The process is performed continuously
so as to accumulate the accumulating operation time period 12. Thereby,
the surplus operation time of the filter core 1 is determined.
[0019] Therefore, the record of the chip 11 of the filter core
1 is always retained in a new state no matter whether the filter
core 1 is installed in the water filter device, even the water filter
device can determine whether the filter core 1 is a set filter core
so as to provide data to user to determine whether it is necessary
to update the filter core 1. Moreover, the overdue filter core will
not be used.
[0020] Referring to FIGS. 3 and 5 in the present invention, the
signal communication between the joint 24 and the control unit 21
can be performed by wireless communication. In the wireless communication,
a sensor card 35 is installed at the joint 24. The sensor card 35
is formed by a chip 37 and a coil antenna 36. A card reader 22 is
installed at the control unit 21. In operation, the card reader
22 will emit radio frequency wave signals to the sensor card 35.
The sensor card 35 will receive the signals from the coil antenna
36. Then power is induced by the radio frequency wave. Then the
chip 37 will resend a set of special codes to the card reader 22.
Thereby, the signals are communicated wirelessly.
[0021] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the present
invention, and all such modifications as would be obvious to one
skilled in the art are intended to be included within the scope
of the following claims. |
