Description
Technical field
The utility model relates to a kind of detection probe that is used for the anti-lack of water detection of small household electrical appliance, anti-spilled detection and water temperature detection etc.
Background technology
Electric-heating thermos in the market, soy bean milk making machine, electric coffee maker, the detection probe performance of the designed uses of small household electrical appliance such as water dispenser is single, for finishing multinomial detection control function, general small household appliances have to be provided with the single detection probe of a plurality of performances in product, as devices such as anti-lack of water detection, anti-spilled detection, water temperature detections, thereby make the structure complicated of small household electrical appliance, the manufacturing cost height, production efficiency is low, and then has caused the waste of resource.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of structure of simplifying product, reduces cost, collects the detection probe that multi-functional detection is an one.
The purpose of this utility model is to realize like this.
A kind of detection probe of small household electrical appliance, comprise a test rod, the lower port sealing of test rod, the upper end of test rod is provided with external thread and signal is derived line, also be with one on the described test rod and detect conductor, the lower port that detects conductor is higher than the lower port of test rod, and the upper end of detecting conductor is provided with the signal extension line, is separated with insulation course between detection conductor and test rod.
Above-mentioned purpose also can be done further perfect by following technical proposals.
Described insulator divides two sections, and epimere is that resin insulator can make the detection conductor be fixed on the test rod, and hypomere is cannula-like for the silicone insulation body, and the lower port of hypomere insulator is detecting between conductor lower port and the test rod lower port.
But described test rod solid or ducted body, its shape is right cylinder.
Ducted body bottom at test rod is provided with thermistor, and the signal conductor of thermistor stretches out from the upper port of test rod, is provided with insulation course between the inwall of thermistor and test rod.
Described test rod and detection conductor are metallic conductor, and test rod is that height of water level detects, and detecting conductor is the detection of overflowing of water.
The utility model principle of work is to utilize metallic conductor as the input body, and constitutes the loop between water and the public ground, utilizes water (or bubble) to touch metal shell and forms being switched on or switched off as detection signal of access loop, implements control by control circuit.Utilize built-in thermistor resistance with the variation of ambient temperature as detection signal, convert corresponding temperature data to by control circuit and realize that water temperature detects control function, meanwhile, control circuit for example can be realized the detection signal that obtains motor, unit control such as heat-producing device.
The utility model is simple in structure, integrates multinomial measuring ability, and working service is convenient, and applied range is stable and reliable for performance, simplifies the structure of small household electrical appliance.
