Description
Technical field
The utility model relates to water level detection circuit, especially the electrodeless water level detection circuit of fluid box.
Background technology
The condensate tank of dehumidifier that current direct drinking fountain, pipeline machine, water purifier, boiled water machine etc. have cistern device or equipment is comparatively simple, usually only has the instruction of the full state of water or discontented state, is difficult to the concrete state of water level in clear and definite water tank.Adopt the detection mode of electric capacity pick-up unit can be made malfunctioning because of the change of temperature, air pressure, water temperature in addition, also not have at present a kind of can the electrodeless condensate tank of dehumidifier of active adjustment.
Summary of the invention
Water position status in water tank can not be specifically indicated in order to overcome existing condensate tank of dehumidifier, condenser type water level detecting can because of the change of temperature, air pressure, water temperature thus the deficiency making pick-up unit malfunctioning in addition, and the utility model provides a kind of fluid box electrodeless water level detection circuit.
The technical scheme in the invention for solving the technical problem is: the electrodeless water level detection circuit of fluid box, comprise MCU control chip, power end and the earth terminal of described control chip are provided with mu balanced circuit, and described MCU control chip input/output terminal is connected to the first touch sensible dish and the second touch sensible dish.
Further, also comprise the pcb board be arranged in fluid box, described first touch sensible dish is arranged on above-mentioned pcb board in the mode of PCB cabling, and described second touch sensible dish is arranged in the first touch sensible dish sidepiece in the mode of pad.
Further, for making MCU working stability, described MCU control chip power end and earth terminal are parallel with the first electric capacity and the second electric capacity.
Further, described first capacitance value is 10 microfarads, and described second capacitance value is 0.1 microfarad.
Further, for ensureing to measure accurately water level situation in fluid box, described MCU control chip having induction control end, described induction control end being connected to the 3rd electric capacity, described 3rd capacitance value is 0.01 microfarad.
Further, described MCU control chip is the microcontroller of built-in capacitance type touch key-press function.
Further, for making the first touch sensible dish obtain waterlevel data more accurately, the wire shaped of walking of described first touch sensible dish is longitudinal square wave.
In use, when SEA LEVEL VARIATION, liquid level contacts the first touch sensible dish to the utility model, causes the capacitance variations on the first touch sensible dish, and data are sent to MCU control chip by the first touch sensible dish, process.The collection capacitance that other second touch sensible dish is interrupted, compares process with the first touch sensible dish capacitance data simultaneously, to ensure the data that the first touch sensible dish records, indicates timely water level in fluid box.
The beneficial effects of the utility model are: can fluid level data in Real-Time Monitoring fluid box, make user can be good at understanding the situation grasping the inside liquid level of liquid; That can be interrupted carry out active correction to Monitoring Data, and making can not affect measured value because of the change of the environmental factors such as temperature, air pressure, water temperature, ensure that the accuracy of measurement data.
