Abstract
The utility model provides a simple shower water level indicator, which is composed of a probe needing only a conducting wire to switch in the water tank, a comparison circuit and a luminous tube. A water level controller can be composed of a probe, a comparison circuit and a triode relay. The utility model has the advantages of simple structure and can exactly recognize or control the water surface position in the water tank.
Description
The utility model relates to a kind of by original creation probe and circuit level displaying device dimerous; Also can repack water-level control apparatus into.
At present, the demonstration of water surface site is all with reverser driven for emitting lights pipe in the shower water tank, and one group of independent circuits shows one by one.Complex structure, poor reliability, and be difficult for assembling.
The purpose of this utility model is to provide a kind of shower water level to show and water level controller, adopts and can use newly-designed probe, has simplified circuit structure greatly.
The purpose of this utility model is achieved in that to be established to give by comparer one end puts voltage, and end is by probe input water level signal in addition, both relatively after, do corresponding demonstration by luminotron; Remove to promote relay as luminotron being changed into triode, by-pass valve control can realize that water level controls automatically.
Owing to adopted such scheme, especially the use of moulding probe makes shower level displaying device designs simplification, and is safe and reliable.
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is a probe of the present utility model.Be by the good resistance in series 1 of calculating, resistance tie lead body is constituted sampling spot 2 outward, and be injection molded into rod 3.Only crossing resistance R 13(with a lead sees Fig. 2) join with power supply (no matter what sampling all is that a lead 4 is drawn, this example is shown as example with Pyatyi).
Fig. 2 is the display circuit fundamental diagram, circuit is by comparison window Ic1---Ic5, luminotron E1---E5, resistance R 1---R13 and capacitor C are formed, R7---R12 form Pyatyi preset voltage UA---UE, will be with ground wire L---R6 flows into the current signal of circuit, and the voltage V0 that forms on R6 compares with preset voltage, the variation of U0 is by probe---the electric current of the last serial of L output changes to be provided, and how much causes that by water short circuit probe resistance size of current decides.Make corresponding demonstration by luminotron.Capacitor C filters clutter in the circuit; Diode O isolates positive potential output negative signal.
The course of work is as follows:
When in the case when anhydrous, U0=0＜UA～UE
When water logging there is not a point, UA＜UO＜UE, the E1 lamp is bright.By that analogy.
When water logging there is not the e point, UA～UE＜U0, the E1-E5 lamp is bright entirely.
Fig. 3 is the control principle sketch.In the enforcement, be to change the luminotron among Fig. 2 into triode, resistance changes relay J into, can become water-level control apparatus.
Claims (3)
1, a kind of shower level displaying device is made up of probe, comparator circuit, luminotron, it is characterized in that: only be connected with head with a lead, the current signal and the preset voltage that are flowed into circuit by ground wire are relatively differentiated the water level height, do corresponding demonstration by luminotron.
2, shower level displaying device according to claim 1 is characterized in that: probe is to become rod by as calculated resistance in series injection moulding or embedding, and constitutes as rapier line eduction rod between resistance is outer.
3, shower level displaying device according to claim 1 is characterized in that: replace former luminotron to go for motor type relay with triode, can form water-level control apparatus.
