Description
Technical field
The present invention relates to flowmeter technical field, more particularly to the water meter that a kind of arrearage is automatically reminded to.
Background technology
At present, known tap water meter, mainly mechanical metering water meter is recorded the use of water by mechanical manipulator
Amount, record quantity is not easy to lose, belongs to non electric performance table tool, and without data exchanging function, without communication capacity, intelligence depends on people
Work meter reading, due to the backwardness of main water metering equipment, manual metering is difficult, often has pretermission, estimates and copy phenomenon.With people's life water
Flat increasingly raising is advanced by leaps and bounds with urban construction level, and the building automatic level of residential building also develops accordingly, in
It is that new requirement is proposed to traditional table row industry of water, electricity, gas three, enters high-end residential instead of common water meter by Intelligent watermeter
Also the certainty in epoch is turned into, IC-card water meter solves expense and is in arrears with problem；IC-card water meter be it is a kind of using modern microelectronic technology,
Modern Transducer Technology, intellective IC card technology are measured to water consumption and carry out the new type water of water data transmission and settlement bargain
Table, existing IC-card wrist-watch is mainly made up of essentic-water-meter, water meter case, and IC-card socket is provided with water meter case, and the IC-card leads to
In the water meter case for crossing IC-card socket insertion intellectual water meter, because IC-card socket is easily accessible foreign matter upward, and because water meter is general
There is the place of sour gas or other gases and humidity mounted in kitchen, toilet etc., moist gas can hold very much when sealing bad
Easily enter in water meter, make the damaging components such as battery, open circuit potential easily causes control device failure or damage, if mechanically or electrically
Road section failure, then need all to need mechanically and electrically device element dismounting, and handling difficulty is big, maintenance difficult.
In addition, with the continuous renewal of technology, the intellectual water meter occurred now on the market, mainly by two kinds, one kind is IC
Card table, mainly a kind of to realize the water meter for counting and deducting fees by pulse, main advantage is that user is disappeared with IC-card plug-in card
Take, pre paid functionality therein, inferior position is that pulse is possible to because magnetization, or work time are long, and normal function loss is led
Pulse missing is caused, so as to count inaccurate, user once occurred causes pulsed operation not normal and largely steal and use water using magnetic；One
It is remote installed meter to plant, and remote installed meter has two kinds of working methods, and one kind is pulse, and one kind is photoelectricity, passes through teletransmission data and timing
Press for payment of user's water rate, it is possible to cause user a large amount of with being gone away after water before pressing for payment of water rate, or smash water meter so as to
Water is largely stolen to use.Therefore, the prior art is defective, it is necessary to improve.
The content of the invention

Show so that when the water meter of light dark place or the crowd of dysphotia check water meter, can also understand the remaining feelings of understanding water rate
Condition, it is very easy to use.Certainly button also can be set with GPRS communication units to be connected, so as to realize that user can use smart machine
The switch of control button, easily to check water meter.Pass through the setting of button so that display screen and light just can works when checking
Make, and be closed when water meter is not checked, save electric energy.
In one preferred scheme, the back of watchcase 1 is provided with rechargeable battery, to be powered to each element in water meter.
In such scheme, water meter is powered by rechargeable battery, it is to avoid the trace arrangements of external power supply, improved
The aesthetic property of water meter, and water meter is mostly installed in the wet environments such as kitichen and toilet, it is to avoid the access of external circuit, is improved
The security that water meter is used.
In one preferred scheme, the check valve 8 is made up of multiple electromagnetically lodicules 10 and axis 11, multiple electromagnetism
One end of property lodicule 10 is connected to the axis 11, and each angle electromagnetically between lodicule 10 is consistent, the electricity
Magnetic lodicule 10 can centered on axis 11 single direction rotation；The size and shape of the electromagnetically lodicule 10 and the watchcase 1
Water inlet 6 is identical.
In such scheme, by setting the size and shape of electromagnetically lodicule identical with water inlet, it ensure that in list
In the case of being closed to valve, passing through for current is not had.And electromagnetically lodicule be set to can only be along axis single direction rotation, it is to avoid
Current flow back, so as to avoid water steathily.
In one preferred scheme, the edge of the water inlet 6 is provided with the side attracting with the magnetic force of electromagnetically lodicule 10
Groove, the electromagnetically lodicule 10 is connected to the rechargeable battery, and the check valve 8 is in closure, and the rechargeable battery is to described
Electromagnetically lodicule 10 is powered, so that the electromagnetically lodicule 10 and the magnetic force of water inlet 6 are attracting, the water inlet 6 is by electromagnetism
Property lodicule 10 is closed；The check valve 8 is when opening, and the rechargeable battery disconnects with the electromagnetically lodicule 10, so that described
Electromagnetically lodicule 10 loses magnetism, and the electromagnetically lodicule 10 is in porch 6 along the middle shaft rotation.
In such scheme, by setting electromagnetically lodicule, it is ensured that when check valve needs to close, make by magnetic force
Electromagnetically lodicule closes water inlet, and when check valve needs to open, because magnetic force disappears, electromagnetically lodicule can be by water
The impulsive force of stream quickly rotates, so as to current pass through it is unaffected.
In one preferred scheme, the outer rim of the electromagnetically lodicule 10 is provided with silicone gasket 12.
In such scheme, by setting silicone gasket at the edge of electromagnetically lodicule, further increase and electromagnetically starch
Sealing between piece and water inlet, so as to avoid water meter leak.
In one preferred scheme, hose-proof generator is connected with after the check valve 8, the hose-proof generator is connected to described
Rechargeable battery.
In such scheme, by connecting hose-proof generator after check valve, current by when, the flowings of current drives
Electromagnetically lodicule is rotated, so that being generated electricity using current, then electricity is stored in rechargeable battery, utilization is realized
Generating power by water current provides electric energy for water meter, saves the use cost of user.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
