The base electrode (14) of the transistor (13) is connected with the sampling lines (18); the heights of the sampling lines (18) are unequal, and the sampling lines (18) are arranged in a water box (17); an emitter electrode (12) is connected with the negative electrode of a power supply; a collecting electrode (11) is connected in series with the luminous diode (9) to be connected with the positive electrode of the power supply; the total circuit of the power supply (1) is connected in series with an indicating light (8), a resistor (10) and a button (19). When the sampling lines of the base electrode of a transistor contact water in the water tank, the luminous diode which is connected in series with the collecting electrode is directly turned on, a water level can be shown, the height of the water level in the water tank can be efficiently mastered, and the utility model is suitable for families and places with water storage facilities.
Description
The utility model relates to water level gauge, particularly a kind of domestic electronic water level gauge.
In the prior art, hot and cold water water storage equipment is installed pinnacled space, uses a glass tube to make moisture storage capacity and monitors.The glass tube fouling is turned to be yellow when serious, can't understand water tank at all and also have how much water.Clean have more than is needed how long can the jaundice again in back, need by torch during observation, even just can see clearly with stool station height.Some family waters tank and is filled in the roof, especially old man and children is seen that water level is made troubles and potential danger.
The purpose of this utility model is: a kind of domestic electronic water level gauge that utilizes the characteristics of transistor principle to be made into is provided, according to the bright of water level indicator light on the water level gauge and putting out, can grasps the height of water level in the water tank effectively.
Formation of the present utility model: by light emitting diode, transistor, sample line and power supply total loop are formed, base stage (14) on the transistor (13) is formed six conductor cable (15), be connected with the sample line (18) that height does not wait by patching (16), sample line (18) places in the water tank (17), connect positive source behind collector (11) the serial connection light emitting diode (9) on the transistor (13), emitter (12) on the transistor (13) connects power cathode, go up tandem working pilot lamp (8) at power supply total loop (1), resistance (10) and button (19) are with transistor, the light emitting diode connection is placed in the transparent shell.Six transistors (13) and six light emitting diodes (9) are arranged in order up and down, the highest transistor (13), and base stage connects the highest sample line (18), and the collector series connection light emitting diode is made full water indicator lamp (7); Inferior high transistor (13), base stage connects time high sample line (18), and the collector series connection light emitting diode is made time high water stage pilot lamp (6); In high transistor (13), high sample line during base stage connects, collector series connection light emitting diode, high water stage pilot lamp (5) in the work; In low transistor (13), low sample line during base stage connects, collector series connection light emitting diode, low-water level pilot lamp (4) in the work; Inferior low transistor (13), base stage connect hands over low sample line (18), and the collector series connection light emitting diode is made time low-water level pilot lamp (3); Minimum transistor (13), base stage connects minimum sample line (18), and the collector series connection light emitting diode is made lowest water level pilot lamp (2).
Compared with the prior art, the utility model is simple in structure, and is economical and practical, and simple installation is aesthetic in appearance, and is safe and reliable, is convenient to observe water level.
Accompanying drawing is the utility model structural representation.
Embodiment of the present utility model: as shown in drawings, base stage (14) on six transistors (13) is formed six conductor cable (15), be connected with the sample line (18) that height does not wait respectively by patching (16), sample line (18) inserts in the water tank (17), emitter (12) on six transistors (13) connects the power cathode on the power supply total loop (1), behind collector (11) the serial connection light emitting diode (9), connect the positive source on the power supply total loop (1), power supply total loop (1) is gone up tandem working pilot lamp (8), resistance (10) and button (19), six light emitting diodes (9) are represented full water indicator lamp (7) from top to bottom respectively, inferior high water stage pilot lamp (6), middle high water stage pilot lamp (5), middle low-water level fingering lamp (4), inferior low-water level pilot lamp (3), lowest water level pilot lamp (2).
Power supply is direct current 3V (common No. five or No. seven battery 2 joints), plus earth, when certain transistor base sample line contacts water in water tank, base potential is higher than emitter, base stage to emitter has a weak current to pass through, under this function of current, an electric current that is enough to light emitting diode the is lighted emitter of flowing through was directly lighted the light emitting diode that is serially connected on the collector during collector produced.At this moment the sample line of representing this water level is submerged in the water.If light emitting diode does not work, the base stage sample line of then representing this water level does not contact the water in the water tank at open-circuit condition.Thereby, create the device of desirable observation moisture storage capacity with the simplest circuit and few electronic original part and cheap cost.
This water level gauge housing is cast with transparent plastic or glass, and profile can be various animals, building model; Plant, modelling of human body or mechanical type bodies such as automobile, steamer are to reach attractive in appearance, pleasing purpose.Stay a long narrow cavity in the abdomen, will light emitting diode and transistor connect the back and arrange, and, fix each contact, circuit and all electronic original parts, and guaranteed waterproof and dampproof shockproofly with this with the disposable pouring encapsulation of epoxy resin, be for a long time exquisitely carved pure and fresh bright and clear simultaneously.
