A kind of magnet rotor counting structure and flowmeterTechnical field
The present invention relates to metering device technical field, be specifically related to a kind of magnet rotor counting structure and little water can be measuredThe metering device of stream.
Background technology
Water meter is the common tool in resident's daily life, calculates, by water meter, the water consumption that every household is daily.
The most modal water meter is rotor water gauge, and the operation principle of rotor water gauge is: be provided with leaf inside water meterWheel, the blade of impeller is perpendicular with inflow direction, and under the drive of current, impeller rotates around impeller axle, and current are the most anxious, bladeVelocity of rotation is the fastest.Meanwhile, a little gear, little gear and other gear wheel is had to engage, such as above impeller axle: and " tenSystem number gear " engagement, whenever little gear turns ten circles, " decimal number gear " just turns around.The reading of gear shows at water meterOn the dial plate at top so that user is read.This kind of water meter by it is the most inexpensive, can in wet environment life-time service andWithout maintenance, and without power supply, have a power failure and nor affect on work.
But, during owing to engaging each other between the little gear on impeller axle and other gear, also can bear during pinion rotationFrictional force, therefore, when water meter counts by calculating the revolution of gear wheel, easily exists when water velocity is less, and current rushThe power hitting impeller is not enough between impeller and each gear pair motion, thus water meter occurs without counting, and flow measurement is notProblem accurately.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is to overcome water meter middle period wheel shaft rotating cycle in prior art to be logicalThe kind of drive crossing gear engagement is delivered on counting gear measure through some gears, rubs between engaging due to gearPower is relatively big, and weep cannot rotate by impeller axle, and causes the defect cannot measured current under the conditions of weep.
Therefore, the present invention provides a kind of magnet rotor counting structure, it is characterised in that including:

Technical solution of the present invention, has the advantage that
1. the magnet rotor counting structure that the present invention provides, described magnet rotor can occur to turn under the impact of currentDynamic, simultaneously induction apparatus can the rotation of induced magnetism rotor, by experiencing the change of magnetic flux, play the effect of counting.
In prior art, counting process is mainly realized by the transmission between gear, but due in gear-driven mistakeCheng Zhong, is commonly present various friction, therefore can cause under weep state, and the impulsive force of current is not enough to offset between gearVarious frictional force, the number of revolutions causing gear cannot be with the flows match of current.
In the present invention, using electromagnetic conductive and unconventional mechanical conductive, during electromagnetic conductive, energy loss is minimum,Therefore discharge intactly can be reflected by the rotation of magnet rotor, will not be missed.
2. the magnet rotor counting structure that the present invention provides, described magnet rotor core includes: flow direction guider, forHaving the current deflecting passage changed the direction of a stream of water, be arranged between water inlet and magnet rotor, described current deflecting passage willThe current deflecting of described water inlet is to being washed on described magnet rotor, and makes described magnet rotor rotate.
In test process, can parallel with the length direction of the blade of magnet rotor in the direction of current sometimes, and current willMagnet rotor cannot be driven to rotate.Now by flow direction guider, thus it is possible to vary the direction of current, increase magnet rotorFor the sensitivity of current, when the discharge within described rotor case is less, it is also possible to drive described magnet rotor to carry outRotate, enable current to impact magnet rotor, make magnet rotor rotate.
3. the magnet rotor counting structure that the present invention provides, described flow direction guider is worm gear, and described magnetic turnsSub-one end is installed in rotation on the center of described turbine, and the gap between the blade of described worm gear forms described current deflectingPassage.
If the flow direction that current are before flowing through turbine is paralleled with the length direction of magnet rotor blade, then current are by nothingMethod promotes magnet rotor to rotate, but owing to turbo blade self has inclined-plane, therefore can make current generation break-in so that currentThe blade of magnet rotor can be impacted.
4. the flowmeter including magnet rotor counting structure that the present invention provides, including:
Power supply, with thinking that single-chip microcomputer provides electric energy；
Single-chip microcomputer, in order to process the signal of described induction apparatus transmission；
Display, in order to show the signal that described single-chip microcomputer processes；
Described single-chip microcomputer is respectively connected with described display and described induction apparatus.
In actual use, water inlet pipe first passes through the first opening entrance whole water flow measurement dress of molding on housingPut inside, then entered inside magnet rotor counting structure by the water inlet of magnet rotor core；Current pass through magnet rotor meterAfter table structure, entering outlet conduit, outlet conduit is drawn from another first opening part of housing so that current leave whole waterFlow metering device.Meanwhile, being additionally provided with the single-chip microcomputer being connected with induction apparatus in device, single-chip microcomputer is able to receive that the transmission of induction apparatusSignal, and single-chip microcomputer self has cumulative calculation function, and by display, the signal reaction obtained by single-chip microcomputer is at displayOn.
5. the flowmeter including magnet rotor counting structure that the present invention provides, described flowmeter is alsoIncluding the buzzer being arranged in parallel with described display.
When the flowmeter that the present invention provides is applied on the devices such as water purifier, within water purifierThe cleaning of current, needs to regularly replace the filter element of water purifier.So, when on display, the numerical value of display reaches a special valueAfter, now buzzer will send alarm, demonstrate the need for changing filter element.
6. the flowmeter including magnet rotor counting structure that the present invention provides, also includes and described single-chip microcomputerThe zero key of series connection.
When water purifier more finish changing filter element need again to count time, now press zero key, at the counting zero of displayReason.
