Abstract
The invention provides a thermistor type temperature sensor with reliable and stable performance. The thermistor type temperature sensor comprises a temperature sensor inner cup and a temperature outer cup with bottoms provided with through holes and a thermistor type temperature sensing probe; springs with acting force along the vertical direction are arranged between the temperature sensor inner cup and the temperature sensor outer cup; a temperature cover is fixed at the opening of the temperature sensor inner cup; vertical supporting feet are arranged at the bottom of the temperature sensor inner cup; limit seams which are for the supporting feet to insert are formed at the bottom of the temperature sensor outer cup; bottom ends of the supporting feet block the limit seams through deformation after inserting into the limit seams; the thermistor type temperature sensing probe is fixed at the bottom of the temperature sensing side closely; a connecting line of the thermistor type temperature sensor penetrates the bottom holes of the temperature sensor inner cup and the temperature sensor outer cup. According to the thermistor type temperature sensor, the thermistor type temperature sensor replaces traditional magnet steel to serve as a temperature element, temperature limiting control is achieved due to the fact that the connecting line of the thermistor type temperature sensing probe is in direct connection with a circuit control panel, and reliability of the temperature sensor is improved.
Description
Technical field
The present invention relates to temperature detector technical field, be specifically related to a kind of thermistor-type temperature detector.
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.This magnet steel attracting device is higher to the performance requirement of magnet steel, and after long-time use, understands because of a variety of causes and cause magnetic to reduce when magnet steel, and then causes whole magnet steel attracting device to work, and temperature detector lost efficacy.
Summary of the invention
The object of the invention is to propose the thermistor-type temperature detector that a kind of dependable performance is stable.
According to thermistor-type temperature detector provided by the invention, comprise the bottom all interior cup of temperature detector and the temperature detector outer cup of through hole, in described temperature detector, between cup and temperature detector outer cup, be provided with acting force spring vertically, 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, described temperature detector outer cup bottom is provided with the spacing seam inserting for described feet, described spacing seam is blocked by distortion after inserting described spacing seam in described feet bottom, key is also to comprise thermistor-type temperature-sensing probe, described thermistor-type temperature-sensing probe is close to the bottom surface that is fixed on described temperature-sensitive cap, the connecting line of described thermistor-type temperature-sensing probe passes the through hole of the interior cup of described temperature detector and temperature detector outer cup bottom successively.
Thermistor-type temperature detector of the present invention, adopt thermistor probe to replace traditional magnet steel as temperature-sensing element, the direct connecting circuit control panel of connecting line by thermistor probe can be realized limit temperature control, the situation that there will not be magnet steel loss of excitation to cause temperature detector to lose efficacy, has improved the reliability of temperature detector; Do not need again to change the structure of traditional temperature detector outer cup and interior cup, saved cost simultaneously.
Further, described thermistor-type temperature-sensing probe is fixed by the supporting cover being overlapped in described temperature-sensitive cap and temperature detector between the rim of a cup of cup, 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 be fixed on the bottom surface of temperature-sensitive cap by modes such as welding, cast flexible glue, as preferred embodiment, and can be by the supporting cover fixed form with supporting base.
Further, in described temperature detector cup bottom through-hole interior week be connected with solidus frame downwards, the both sides of described solidus frame are provided with perforation or the 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 after through the perforation of solidus frame or gap, prevents that the connecting line of thermistor-type temperature-sensing probe from departing from temperature-sensitive cap by thermistor-type temperature-sensing probe band, affects temperature-sensitive effect.
