Description
Technical field
A kind of water purifier leakage inspector, the detecting electrode charging that its feature is consisted of storage voltage capacitance and the via pad that is distributed in PCB surrounding current-limiting charge resistance, leaking forms leak water detdction to capacitor discharge mode.
Background technology
Current water purifier leakage inspector is the mode that pull-up biasing resistor adds parallel zigzag tooth plate electrode, and what pull-up resistor contacted with parallel pole leak, and equivalent resistance that current form is connected.In time leaking, the resistance value of the water between parallel pole relates to factor and comprises water quality conductive ion content, the water yield, the uncertain factors such as contact area, cause water as the instability of conductor resistance resistance, its numerical value change is linear, makes which unstable, report by mistake or do not report phenomenon very general, as south wind wet weather will cause the warning of this equipment.Simultaneously, pure water, tap water, the conductance resistance parameter difference such as condensed water are huge, the method testing circuit is difficult to accomplish to tackle this several water quality requirement, and the reliable and stable operation of energy, make the reliability of this device low, cause about more than 85% actual user to cancel this function, illustrate that its mode has very large drawback.
In addition, in the probe that leaks, mostly be the mode that one side pcb board applies the parallel staggered tooth plate of tin Copper Foil at present, electrode one side upward, because The natural flow of water always proceeds from a higher level to a lower one and circuit board resistance welding ointment layer non-hydrophilic, and the tension force reason of water, cause current can not the electrode being positioned at upper surface on reliable contacts circuit board, surface of contact, because the uncertainty of the current that leak, causes the reliability of leak water detdction low upward.Minority adopts the mode of two or many parallel metal probes, and metal probe mode is difficult to settle in the use of reality, and detection contact is single, detecting water leakage contact area is limited, and the randomness of current, cause reliability low, easily cause the situation mode that this report or not.
Summary of the invention
In order to overcome the deficiency of the linear leak water detdction mode of existing pull-up resistor, the utility model provides kind of a method, arranges electric capacity in-between the electrodes, by current-limiting resistance to capacitor charging, forms condenser type leak water detdction.
The utility model solves the technical scheme that its technical matters adopts: on the basis of double-sided PCB board material, the Copper Foil X-shaped scribbling solder mask is scattered in the two poles of the earth of intersection, PCB edge uniform intervals zonation eyelet welding dish, be connected with the Copper Foil of opposed polarity respectively, form natural Water leakage detecting electrode, UF level electric capacity connects Copper Foil two electrode that X intersects, power supply is charged to two electrodes and electric capacity by current-limiting resistance, charge storage is in X electrode and electric capacity, time pad probes detects and leaks, electric capacity discharges rapidly decompression, judges water leakage.
The beneficial effects of the utility model are: the via pad probe of double-sided PCB board surrounding more meets current rule of leaking, and just right interval is unlikely to again as wet weather causes wrong report.Resistance charges, electric capacity accumulate, and leak probe discharge mode, forms detectable signal with/without the digital manner of (1/0), is different from traditional linear mode, has accuracy high.By regulating charging resistor just can to leak trigger parameter by accurate adjustment, accuracy is high, and volume production has consistance.Digital manner with/without (1/0) facilitates MCU or exports the direct process of executive component.The lower limit resistance set-up mode of charging resistor prevents the wrong report as south wind wet weather causes.

Embodiment
In Fig. 1, there is the Copper Foil scribbling welding resistance insulation course in double-sided PCB board (1) front, Copper Foil comprises negative Copper Foil (2), positive Copper Foil (3), connected by the Copper Foil scribbling welding resistance insulation course of double-sided PCB board (1) bottom surface and via hole (10) between two positive Copper Foils (3), form the electrode of x distribution of shapes, pcb board (1) corner is uniformly distributed via pad (4), and respectively with negative Copper Foil (2), positive Copper Foil (3) connect.Via pad (4) forms detecting water leakage by exposed tin coating and pops one's head in.Positive source (5) connects positive Copper Foil (3) by current-limiting resistance (8).Negative Copper Foil (2) power cathode (6) directly connects.Storage voltage capacitance (7) the two poles of the earth connect negative Copper Foil (2), positive Copper Foil (3) respectively.Positive Copper Foil (3) connection signal exports (11).Signal exports (11) and connects water leakage processing module or topworks, and in circuit loop, there are inner resistance in signal processing module or topworks, are equivalent to equivalent resistance (9).What high resistant was selected by signaling module or topworks opens leakage mode.
According to measuring and calculating, current-limiting resistance (8) is according to different quality testing requirement value 500K Ω-5M Ω, and storage voltage capacitance (7) capacity is be advisable between 0.1UF-10UF.Equivalent resistance (9) is greater than current-limiting resistance (8) resistance.. after leakage inspector energising, current-limiting resistance (8) is to storage voltage capacitance (7) charging, equivalent resistance (9) resistance is set and is greater than current-limiting resistance (8), at this moment signal output (10) voltage approximates or a little less than supply voltage, signal exports (10) has voltage signal to export (signal is 1).When connecting negative Copper Foil (2) respectively, when the via pad (4) of positive Copper Foil (3) opposed polarity is leaked and is formed loop, electric capacity is discharged rapidly, signal exports (11) voltage rapidly by high vanishing, and signal processing module or topworks make relative motion rapidly.
Require power supply positive source (5) according to signal processing mode, power cathode (6) institute electrify electrode can be exchanged, and does not change principle and the function of the utility model device.Via pad (4) electrode of x distribution of shapes can be designed to other distribution forms according to sensitivity requirement or environment for use.Double-sided PCB board (1) fixed orifice is installed or double faced adhesive tape mode is installed on current low level, and via pad (4) is this device leak water detdction probe, can be arranged to probe mode, not change the utility model device basic structure principle.Storage voltage capacitance (7), current-limiting resistance (8), for adjustable, tackles different medium and sensitivity.The detecting head be made up of pcb board, Copper Foil, pad can directly be replaced by metal cartridge.
The utility model device utilizes capacitor charge and discharge to form digital leak water detdction mode with presence or absence of water leakage, with traditional resistive linearity aspect ratio, there is optimum configurations accurate, only need to regulate current-limiting resistance (8) resistance parameter just can change the sensitivity of reply different quality conductance difference, mode with presence or absence of signal condition facilitates signal processing module Digital Signal Processing or topworks to perform an action, triggering mode is accurate, and output signal accurately.Be distributed in pcb board (1) surrounding, the Water leakage detecting electrode that the via pad (4) connecting different both positive and negative polarity is formed, more meet water movement mode when leaking actual generation, multi-contact surface improves current opposed polarity eyelet welding dish (4) when occurring that leak and forms the probability in capacitor discharge loop, is unlikely to because humidity causes wrong report simultaneously.It is simple that this device has structure, easily implements, and detects accurately and reliably, the advantage that parameter is accurately adjustable.This device is applicable to the purifiers such as counter-infiltration, ultrafiltration, nanofiltration.
