Description
Technical field
The present invention relates to temperature detector technical field, be specifically related to a kind of thermistor type temperature sensor.
Background technology
Traditional electric cooker temperature detector normally adopts magnet steel attracting device as the switch of limit temperature control electric rice cooker heated, as shown in Figure 1.The performance requirement of this magnet steel attracting device to magnet steel is higher, and when magnet steel can because a variety of causes causes magnetic to reduce, and then cause whole magnet steel attracting device to work after using for a long time, temperature detector lost efficacy.
Summary of the invention
The object of the invention is to propose the stable thermistor type temperature sensor of a kind of dependable performance.
According to thermistor type temperature sensor provided by the invention, cup and temperature detector outer cup in the temperature detector comprising the equal through hole in bottom, acting force spring is vertically provided with between cup and temperature detector outer cup in described temperature detector, in described temperature detector, the rim of a cup of cup is fixed with temperature-sensitive cap, in described temperature detector, the bottom of cup is provided with the feet of vertical direction, the spacing seam inserted for described feet is provided with bottom described temperature detector outer cup, described feet bottom is inserted described spacing seam and is blocked described spacing seam by distortion afterwards, key is also to comprise thermistor-type temperature-sensing probe, described thermistor-type temperature-sensing probe is close to the bottom surface being fixed on described temperature-sensitive cap, the connecting line of described thermistor-type temperature-sensing probe is successively through the through hole bottom cup in described temperature detector and temperature detector outer cup.
Thermistor type temperature sensor of the present invention, thermistor probe is adopted to replace traditional magnet steel as temperature-sensing element, can realize limitting temperature control by the direct connecting circuit control panel of the connecting line of thermistor probe, the situation that there will not be magnet steel loss of excitation to cause temperature detector to lose efficacy, improves the reliability of temperature detector; Do not need again the structure changing traditional temperature detector outer cup and interior cup simultaneously, save cost.
Further, described thermistor-type temperature-sensing probe is fixed by the supporting cover between the rim of a cup that is overlapped on cup in described temperature-sensitive cap and temperature detector, and the middle part of described supporting cover is provided with the supporting base with thermistor-type temperature-sensing probe adaptation.Thermistor-type temperature-sensing probe can pass through such as to weld, pour into a mould the bottom surface that the modes such as flexible glue are fixed on temperature-sensitive cap, as preferred embodiment, by being with the supporting cover fixed form of supporting base.
Further, in described temperature detector cup bottom through-hole inner circumferential under be connected with solidus frame, the both sides of described solidus frame are provided with the perforation or gap that the connecting line for described thermistor-type temperature-sensing probe passes.By increasing solidus frame, the connecting line of thermistor-type temperature-sensing probe is fixed through after the perforation of solidus frame or gap, prevents the connecting line of thermistor-type temperature-sensing probe from thermistor-type temperature-sensing probe band is departed from temperature-sensitive cap, affects temperature-sensitive effect.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of existing temperature detector.
Fig. 2 is sectional structure schematic diagram of the present invention.
Fig. 3 be temperature detector outer cup of the present invention look up structural representation.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As Fig. 2, 3, thermistor type temperature sensor of the present invention, cup 1 and temperature detector outer cup 2 in the temperature detector comprising the equal through hole in bottom, acting force spring 3 is vertically provided with between cup 1 and temperature detector outer cup 2 in temperature detector, in temperature detector, the rim of a cup of cup 1 is fixed with temperature-sensitive cap 4, in temperature detector, the bottom of cup 1 is provided with the feet 11 of vertical direction, 12, 13, be provided with for 11 bottom temperature detector outer cup 2, 12, the spacing seam 21 that 13 feets insert, 22, 23, feet 11, 12, spacing seam 21 is inserted in the bottom of 13, 22, spacing seam 21 is blocked by distortion after 23, 22, 23, also comprise thermistor-type temperature-sensing probe 5, thermistor-type temperature-sensing probe 5 is close to the bottom surface being fixed on temperature-sensitive cap 4, the connecting line 51 of thermistor-type temperature-sensing probe 5 is successively through the through hole bottom cup 1 in temperature detector and temperature detector outer cup 2.Thermistor-type temperature-sensing probe 5 is fixed by the supporting cover 6 between the rim of a cup that is overlapped on cup 1 in temperature-sensitive cap 4 and temperature detector, and the middle part of supporting cover 6 is provided with the supporting base 61 with thermistor-type temperature-sensing probe 5 adaptation.In temperature detector cup 1 bottom through-hole inner circumferential under be connected with solidus frame 7, the both sides of solidus frame 7 are provided with the gap 71 and 72 that the connecting line for thermistor-type temperature-sensing probe passes.
The present invention adopts thermistor probe 5 to replace traditional magnet steel as temperature-sensing element, can realize limitting temperature control by the direct connecting circuit control panel of the connecting line 51 of thermistor probe 5, the situation that there will not be magnet steel loss of excitation to cause temperature detector to lose efficacy, improves the reliability of temperature detector; Do not need again the structure changing traditional temperature detector outer cup 2 and interior cup 1 simultaneously, save cost.
