The technical solution of the utility model is: a kind of level gauge of liquid heater by electromagnetic induction, comprise housing, non-conductor container, magnet exciting coil, metal foil lamellar body is arranged in non-conductor container and within the scope of the magnetic line of force producing in magnet exciting coil, in described non-conductor container with on the contour position of liquid level control line, liquid-level switch is set, described liquid-level switch is connected on main control circuit.
Described magnet exciting coil is tubular.
On described metal foil lamellar body, be provided with discharge groove or discharge aperture.
Described metal foil lamellar body is split ring or the closed circle that head and the tail disconnect.
Described non-conductor container is to be obtained by glass or pottery or plastics.
Sidewall or the bottom of described non-conductor container are provided with perforate, and described liquid-level switch enters into internal tank through perforate, is also provided with sealing ring in described perforate.
Described liquid-level switch is float type level switch.
Described float type level switch comprises determines reed, movable contact spring, float, is provided with the magnet for magnetic movable contact spring on float.
The beneficial effects of the utility model are: because the utility model is provided with liquid-level switch, when the water level of liquid heater is during lower than liquid-level switch, the action of shake-up liquid-level switch, magnet exciting coil control circuit major loop disconnects, electromagnetic induction heating conductor internal vortex disappears, and stops water heating, and water level no longer reduces, effectively effect prevents that the electricity piece causing because water level is too low from damaging and potential safety hazard, prevents water heater dry combustion method.
Apply liquid heater by electromagnetic induction of the present utility model and add hot tap-water, can in water body, there are electric discharge phenomena in the discharge aperture/groove of its becket inside, by water electrolysis, generation is of value to the small-micelle water of health, have huge economic and social benefits, applying of it will further improve people's living standard and healthy.

Fig. 2 is another mounting structure schematic diagram of switch rod of the utility model level gauge.
Fig. 3 is the structural representation of the utility model float type level switch.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Embodiment mono-
Referring to Fig. 1-2, the level gauge of liquid heater by electromagnetic induction of the present utility model, comprise housing, non-conductor container 3, the magnet exciting coil 1 of tubular, metal foil lamellar body 2 is arranged in non-conductor container 3 and within the scope of the magnetic line of force producing in magnet exciting coil 1, in non-conductor container 3 with on the contour position of liquid level control line, liquid-level switch 7 is set, described liquid-level switch is connected on main control circuit, and magnet exciting coil 1 is electrically connected to circuit board 8.Non-conductor container 3 is to be made by glass or pottery, plastic or other material, in liquid injecting container, by 2 heating of metal foil lamellar body.One switch rod 6 is set on the lid 5 above container, in the inside of switch rod, liquid-level switch 7 is set, when lid cap seal container, the liquid-level switch 7 in switch rod is just on liquid level control line.Or, in sidewall or the bottom of container, perforate is set, make switch rod 6 enter into internal tank through perforate, thereby liquid-level switch 7 is placed on liquid level control line.And in the perforate of container, be also provided with sealing ring 10, prevent that liquid in container is from tapping seepage.This liquid-level switch is electric pole type liquid-level switch, and when water level is during higher than liquid-level switch, switch is closed, and when water level is during lower than liquid-level switch, switch disconnects, thereby touch main control circuit, disconnects, and magnet exciting coil quits work, and metal foil lamellar body no longer produces heat.
Liquid heater by electromagnetic induction of the present utility model adopts magnetic field induction eddy heating for heating principle, and under the effect of magnet exciting coil alternating magnetic field, underwater gold belongs to the inner eddy current that forms of ring, and heating, heats water rapidly.In the utility model, on metal foil lamellar body, discharge groove can be set, also discharge aperture can be set, metal foil lamellar body can be the metal ring body of sealing, can be also split ring.On circuit board 8, gilled radiator is set, near radiator, be provided with fan 9, on housing, the position of corresponding radiator and fan 9 arranges louvre, and the heat that control circuit when work produces can be distributed rapidly, thereby provides good, a stable working environment for system.
Metal foil lamellar body forms internal vortex and generates heat under the galvanomagnetic-effect effect of magnet exciting coil, and its discharge groove or discharge aperture generation electric discharge phenomena, by water light current solution, the hydrogen bond of hydrone is disconnected, thereby promote the water of macromolecular mass to be converted into small-micelle water.
Embodiment bis-
As a kind of concrete embodiment, on the basis of embodiment mono-, the fixed form of liquid-level switch can adopt following scheme: the sidewall at container arranges a connection sap cavity, the bottom of this connection sap cavity communicates with container, and the water level that makes to be communicated with sap cavity is identical with the water level in container, liquid-level switch is preset on the liquid level control line being communicated with in sap cavity, when the water level in container declines, the water level being communicated with in sap cavity declines thereupon, when water level drops to lower than liquid-level switch, and liquid-level switch action.
Embodiment tri-
As another concrete embodiment, on the basis of embodiment mono-or embodiment bis-, the element of selecting a kind of float type level switch to control as liquid level.As shown in Figure 3, this float type level switch comprises switch base 11, contact chamber 12, float cavity 13, the first reed 14, the second reed 15, float 17, two reed relative separation arrange, be connected with the wire in switch base 11, float 17 is arranged in float cavity 13, float cavity 13 is positioned at the below of a pair of reed, is provided with the magnet 16 for magnetic movable contact spring on float.Float type level switch, magnet exciting coil, A.C. contactor are connected in series.Liquid level in container is higher than float type level switch, and due to buoyancy, float 17 rises to the top of float cavity 13, under the magnetic fields of magnet 16, and two reed adhesives, A.C. contactor energising, magnet exciting coil is started working.When liquid level is during lower than float type level switch, float, because Action of Gravity Field declines, loses after magnetic fields, determines reed separated with movable contact spring, and A.C. contactor power-off is also cut off circuit power, and magnet exciting coil quits work.
Disclosed is above only specific embodiment of the utility model; do not form the restriction to the utility model protection domain; all changes without process creative work of doing according to technical solutions of the utility model, within all should dropping on protection domain utility model of the present utility model.
