Description
Technical field
The utility model relates to a kind of assembled household electrical appliances NTC temperature sensor, belongs to temperature sensor technical field.
Background technology
Traditional soybean milk machine is the heating-up temperature of monitoring soya-bean milk, conventionally temperature sensor is arranged on the fuselage of soy bean milk making machine and is inserted in that cup is inner to be contacted with liquid.Temperature sensor mainly by thermistor, play induction and stainless steel casing and wire and the liquid level signal line etc. of protective effect form; thermistor is arranged on the variation of housing internal induction water temperature; along with the resistance of the variation thermistor of water temperature also and then changes; then resistance is passed on control circuit board; thereby realizing temperature controls; by liquid level signal line, liquid level signal is also delivered on control panel simultaneously; when water level is lower than certain height time; will output signal, so just can reach the effect of anti-dry.Although the part that two wire one end of the temperature sensor of existing structure are connected with thermistor can be fixed in metal shell by epoxy resin, connect more firm, liquid level signal line is to be welded on metal shell by copper strips, because the core of liquid level signal line is thinner, so both tie points are smaller, especially the installation site of temperature sensor is limited, often wire is that the axis with respect to metal shell is curved arrangement, cause liquid level signal line to be connected with metal shell insecure, affect the output of liquid level signal line.Moreover, because passing stainless steel casing, wire is connected with circuit board, when realizing darker thermometric, therefore stainless steel casing and wire that need to be longer, not only can increase stainless steel steel use amount, and wire warping resistance ability is weakened greatly, can not reach actual cleaning requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, flexibly mobile, the assembled household electrical appliances NTC temperature sensor of warping resistance.
The utility model is that the technical scheme achieving the above object is: a kind of assembled household electrical appliances NTC temperature sensor, comprise thermistor, stainless steel casing and the wire with sealed end, thermistor is arranged on the sealed end of stainless steel casing and is connected with wire, thermistor and wire by epoxy sealing in stainless steel casing, it is characterized in that: described wire is Teflon lead, the rear side of described stainless steel casing is inserted into fixedly in base, fixedly on base, there is the shaft shoulder, be positioned at the preceding thread axle of the both sides of the shaft shoulder, rear thread axle and the coupling shaft that is positioned at rear thread axle rear portion, ring set is on stainless steel casing, front nut sleeve is screwed on preceding thread axle and by O-ring seal and is pressed on upper stainless steel casing, Hose Jacket is on the coupling shaft of fixing base, back nut cover is screwed on the rear thread axle of fixing base and flexible pipe is crimped on coupling shaft, its one end of spring being arranged in flexible pipe is connected with coupling shaft, the other end is connected with liquid level signal line, wire and liquid level signal line pass flexible pipe.
The utility model is arranged on thermistor and wire sealing in stainless steel casing, again by stainless steel casing releasable connection on fixing base, fixedly base is tightly connected by O-ring seal and stainless steel casing, can effectively shorten the length of temperature sensor stainless steel casing, reduce stainless steel steel use amount, flexibly mobile, thermometric depth is long.The wire that the utility model adopts the warping resistance Teflon lead strong, that wire diameter is little of fire-resistant nontoxic to draw as sensor signal; because wire outlet is arranged on fixedly in base; in addition wire can carry out buffer protection by spring again in the junction of the fixedly outlet of base; not easily damaged while making wire encapsulation; warping resistance; can not only improve assembly qualified rate, and the characteristic requirements while being convenient to clean.The utility model is connected in liquid level signal line on spring, not only solves the orientation problem of liquid level signal line, and can also to liquid level signal line, cushion by spring reliable operation.The utility model is connected to flexible pipe fixedly on base, therefore can, by wire and liquid level signal line by spring buffer, facilitate wire and liquid level signal line to be connected with soy bean milk making machine PC plate.
