Description of drawings:
Accompanying drawing is that the utility model adopts piston inductor, optoelectronic switch pattern, alarm condition principle generalized section.
The specific embodiment
Of the present utility model optimum embodiment shown in the accompanying drawing.Power supply 1 provides signal pickup assembly and identification circuit 2 required electric energy.One end of the cylinder body 4 of piston inductor has connecting interface.There is power switch 9 at the A place, the position of the switch of cylinder body; Its B place have connect, photoswitch circuit 3 that luminous tube 3a, 3b constitute; The piston 6 of piston inductor is provided with seal 7 and prevents that the water in the water filter system from leaking outside, and upper cover of piston rod has back-moving spring 8, and indicates warning label on top.Piston 6 can only linear reciprocation move in cylinder body 4.Seal 7 is best with the combined labyrinth and carbon gland spare that adopts the low sassafras that rubs, and also can adopt the metastable lip-type packing of frictional force, can also adopt O-ring seals.One end of back-moving spring 8 acts on the piston, and the other end acts on the cylinder body.Water filter and waterway channel and by-pass valve control constitute filtration system, and this by-pass valve control is arranged on the water outlet end of filter core; This piston inductor is connected the water inlet end of detected filter element.When this valve closing, water filter is in off working state.At this moment, the hydraulic pressure that bears in the waterway channel of cylinder body 4 inner chambers of piston inductor is the highest relatively.The resistance that this hydraulic pressure overcomes piston seal 7 and 8 liang of parts formations of spring is pushed into highest point with piston, and triggers contact switch 9 powered-downs 1.At this moment, can to stretch out the part of cylinder body the highest for piston rod.When water filter moved, the hydraulic pressure pressure reduction at detected filter element water-in and water-out two ends was lower, caused the interior hydraulic pressure force value of cylinder body to reduce to minimum.The resistance that back-moving spring overcomes seal 7 and hydraulic pressure pushed away alarm bit B point with piston, arrived working position.At this moment, to stretch out the part of cylinder body minimum for piston rod.With the change of the running status of water filter, piston moves back and forth in cylinder body.In these moving process, piston all passes through the B place of cylinder body at every turn, but the time of passing through is all at X in second.The filter core of water filter in use for some time, being stopped up gradually by impurity of filter core filtrate causes the hydraulic pressure pressure reduction at detected filter element water-in and water-out two ends to raise gradually, hydraulic pressure pressure is also corresponding in the piston/cylinder raises gradually, the stroke of piston is also shortened gradually, its working position moves to the B point, until arriving the B point.At this moment, piston sends infrared light by luminous tube 3a in the cylinder body 4.Meet light pipe 3b and send infrared light and output low level signal by the reception of the light hole on piston rod luminous tube 3a.Identification circuit detects this low level signal duration greater than X after second, sends recoil alarm user.In addition, the warning label that is on the piston rod of alarm condition position just in time is positioned at indicating range, thereby plays suggesting effect directly perceived.The user finds that in water utilizing process the warning label on the piston rod rests in the indicating range for a long time, just can take measures areput, to the filter core cleaning that recoils.The user recoiled cleaning to filter core after, the stopping state of tested filter core had obtained certain mediation.The hydraulic pressure pressure of its water inlet end reduces, and the working position of respective pistons is once more away from alarm bit B point.After this, repeat above-mentioned alarm procedure.
The optoelectronic switch 3 that the utility model adopts both can be a correlation, also can be reflective.For the former, the sending and receiving light pipe is arranged on the both sides of piston, and a light hole is arranged on the piston rod; For the latter, there is a reflective interface the same side that connect, luminous tube is positioned at piston on the respective pistons, and the infrared light reflection that luminous tube is sent is to connecing on the light pipe.
As improvement of the present utility model, can be at the C point between recoil alarm bit and the working position, other is provided with recoil reset signal harvester.This signal pickup assembly adopts and the identical mode switching circuit of recoil signal pickup assembly.After identification circuit 2 detects the recoil signal, start the operation of reset signal harvester: if detect the reset signal conducting, then identification circuit judges that detected filter element has obtained recoil and cleaned or change, and closes the reset signal harvester immediately; Exist if detect reset signal, judge that then the user is less than cleaning that this filter core is recoiled.Repercussion effect and the life-span of considering filter core are limited, in order to guarantee filter effect, adopt recoil, reset two on-off circuits and identification circuit 2 combinations, the user is carried out filter core change the prompting warning: when identification circuit detects the recoil alarm signal N time, and between adjacent twice recoil alarm signal, detect corresponding reset signal, after then being judged as tested filter core recoil being cleaned through several times, be in the recoil alarm condition, send filter core replacing alarm then for the N time; Exist when identification circuit only detects the signal that recoils, then when this blackout, then be judged as tested filter core and do not obtain the recoil cleaning, and continue use to the situation of stopping up filter core and more become badly, send more renew cartridge prompting then and report to the police.After this, detect the reset signal conducting, judge that then this filter core changes, close the reset signal harvester immediately at identification circuit.
Consider the installation that makes things convenient for water filter, the utility model can adopt dc source.In order to economize on electricity and to avoid long-time the warning that the user is impacted, behind the by-pass valve control of the mass filter of at every turn fetching boiling water, with moving of piston, the utility model device is connected power switch 9 and is started working.When detected filter element is in the alarm condition position, there is 2 of the identification circuits of outage memory function when beginning, to report to the police, but not continues to report to the police service time with water filter.
For adopting the water filter that by-pass valve control is arranged on water inlet, recoil reset position C point is higher than recoil alarm bit B point, power switch position A point and working position.Water filter is stopped up gradually by impurity in use for some time, causes the hydraulic pressure of detected filter element water inlet end to raise gradually, and hydraulic pressure pressure is also corresponding in the piston/cylinder raises gradually, and piston moves the startup power switch.Identification circuit detects recoil alarm user cleaning that recoils during signal; Detect recoil alarm user renew cartridge more during reset signal.
Further improve as the utility model is improved, the cylinder body of piston inductor is provided with the active block stop 5 of adjusting spring pressure.Because it is different that each water filter is pressed the waterway tube of land used, the also corresponding difference of the piston displacement stroke of respective pistons inductor.For this reason, will make transportable active block stop with the cylinder part of spring action into.As with active block stop with holes and cylinder body to be threaded togather.When water filter is installed, waterway tube according to the locality is pressed the position of adjusting active block stop, the pressure of corresponding adjustment spring 8, press thereby make piston adapt to local waterway tube: when the filter core needs recoiled, the piston light hole was just in time aimed at the recoil alarm bit on the cylinder body.
When signal pickup assembly of the present utility model adopted the contact switch circuit, the conductive contact on the piston rod can be distinguished the recoil alert locations of conducting cylinder body and two contact switch circuit on the reset position, exports corresponding Continuity signal.Though contact switch circuit and photoswitch circuit are different, effect all is that the displacement with piston body is converted to the signal of telecommunication and continues the ON time detection for identification circuit.
As another program of the present utility model, the water pressure sensing device can be a spring bend pipe pressure gauge structure.Utilize waterway tube to press and make the manometric copper pipe modification of spring bend pipe produce the principle of swing, the swing by wobble-member triggers the on-off circuit as signals collecting.
As another kind of scheme of the present utility model, hydraulic inductor can be pressure sensor and pressure difference transmitter structure.Convert the variation in water pressure of tested filter core water inlet end to the corresponding signal of telecommunication and flow to identification circuit.
