The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model is further described in conjunction with attached drawing.
As shown in Figure 1, for the structural schematic diagram of the utility model liquid level detection device, including temperature sensor 1 and fixation
Pedestal 2, the temperature sensor 1 are fixed on the firm banking 2.
The connecting pin 101 of the temperature sensor 1 passes through the firm banking 2 to be arranged on the firm banking 2.It is described
Temperature sensor 1 is NTC temperature sensors.The temperature sensor 1 includes multiple temperature sensors.
The connecting pin 101 of the temperature sensor 1 is provided with conducting wire 102, is connect with external control device by conducting wire 102
To transmit electric signal.

Device on.The firm banking 2 is injection molding pedestal or metab or bending punching press pedestal.
Temperature is one of seven big physical quantitys.NTC thermistor is a kind of thermally sensitive semiconductor ceramic element, is had
The feature that reaction is fast, precision is high, stability is good, at low cost, is widely used in all kinds of occasions related with temperature.
Since thermistor itself is a resistance, when electric current flows through thermistor ontology, ontology can generate heat (self-heating),
Electric current is bigger, and fever is more apparent.Due to radiation of heat and conduction, the heat of ontology hair also can be radiated or be passed by body perimeter
A part is gone in export.Assuming that body self-heating cooking is Q, the part radiated away is W, then：
Work as Q>When W, for thermistor mainly by from heat affecting, ontology resistance value can be different with the difference of heat eliminating medium.
As Q=W, the self-heating of thermistor and heat dissipation are in equilibrium state, and ontology resistance value is constant, only with environment temperature
Change and changes.
Work as Q<When W, thermistor is from heat affecting very little, and ontology resistance value is with variation of ambient temperature.
So under fixed high current, thermistor by from heat affecting, the different of heat eliminating medium can be to thermistor
Resistance value generates Different Effects, and when good heat dissipation, the resistance value of thermistor increases；When radiating bad, thermistor resistance decrease.
It is well known that the pyroconductivity of air is far smaller than liquid.Utilize this feature, so that it may with thermistor
Temperature sensor detects the position of liquid.
The utility model is the sensor of electronic type, can at any time feed back to connection with Multi probe, multiposition measuring
Controller.It is more convenient accurate compared to more traditional float type, mechanical liquid level sensor.
The utility model is simple in structure, and NTC temperature sensors use all-sealed structure, is suitable for plurality of liquid, including can
Burning liquid.Solve the problems, such as that electrode type liquid level sensor has potential difference and insulation pressure resistance, or even electric discharge leads to dangerous problem.
The utility model has the function of temperature detection and level sensing two simultaneously, economic performance, can be used for electric kettle,
Electronics vacuum flask, electric cooker, electric pot etc..
More than, the only preferable specific implementation mode of the utility model, but the protection domain of utility model is not limited to
This, any one skilled in the art within the technical scope disclosed by the utility model, the variation that can be readily occurred in
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with right
Subject to the protection domain of claim.
