Description
Technical field
The present invention relates to household electrical appliance spare and accessory parts technical field, and in particular to a kind of temperature for improving sensitivity of thermistor
Spend sensor.
Background technology
Application No. 2017205022966, a kind of entitled patent application of New temperature sensor proposes one kind will
The temperature sensor that the dry burning resistance switch with drag hook of innovative technology is combined with the inside and outside cup structure of existing magnetic steel temperature limiter,
The problem of solving high using the installation dimension precision prescribed of temperature limiter switch needs of the fixed board-like installation with drag hook.But,
In actual use, the temperature sensor of this structure, the Kick type temperature controller due to thermistor and with drag hook is close to aluminium lid material
The conductive cover of matter, the heat major part that conductive cover is absorbed is absorbed by heat transfer by the Kick type temperature controller with drag hook, this meeting
Making the temperature control at thermosensitive resistance measurement inner vessel for electrical cooking-vessel bottom reduces, and influences using effect.
The content of the invention
The purpose of the present invention is to propose to a kind of temperature sensor for improving sensitivity of thermistor.
The temperature sensor for improving sensitivity of thermistor provided according to the present invention, including the Kick type temperature with drag hook
Device, thermistor, inner support, conductive cover, interior cup, outer cup, spring are controlled, the conductive cover is riveted on the upper shed of the interior cup
Place, the under shed of the interior cup is connected to the outer cup bottom to vertical supporting pin, the vertical activity of vertical supporting pin is had
At the spacing seam in portion, be provided with spring at the conductive cover riveting between the bottom of the outer cup, key be also to include every
Heat pad, the heat insulating mattress is arranged between the top surface of the inner top surface of the conductive cover and the Kick type temperature controller with drag hook,
The Kick type temperature controller with drag hook is fixed by inner support, and the thermistor is close to the inner top surface of the conductive cover.
The present invention is by adding heat insulating mattress, such conductive cover institute between the Kick type temperature controller in conductive cover and with drag hook
The heat of absorption is largely reduced by heat transfer by the part that the Kick type temperature controller with drag hook absorbs, so as to reduce to temperature-sensitive
The influence of the temperature at resistance measurement inner vessel for electrical cooking-vessel bottom, improves the sensitivity of thermistor；And due to overheating of electric rice cooker heating
It is relatively slow process, it is relatively low to the sensitivity requirement of the Kick type temperature controller with drag hook as protection element.
Further, the heat insulating mattress is circular ring type packing ring, and the internal perisporium lower end of the annular packing ring is provided with groove.This
The heat insulating mattress of spline structure, can be engaged by clamping, convenient for assembly is same by the aluminium lid of groove and the Kick type temperature controller with drag hook
When, it can prevent heat insulating mattress from shifting, influence the firm of the Kick type temperature controller with drag hook.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structure sectional view of the heat insulating mattress of the present invention.
Embodiment
It is for example involved each to the embodiment of the present invention by the description to embodiment below against accompanying drawing
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Such as Fig. 1, the temperature sensor for improving sensitivity of thermistor of the invention, including the Kick type temperature control with drag hook
Device 1, thermistor 2, inner support 3, conductive cover 4, interior cup 5, outer cup 6, spring 7, conductive cover 4 are riveted at the upper shed of interior cup 5,
The under shed of interior cup 5 is connected to the spacing seam of the bottom of outer cup 6 to vertical supporting pin 51, the vertical activity of vertical supporting pin 51 is had
Spring 7, in addition to heat insulating mattress 8 are provided between the bottom of outer cup 6 at place, the riveting of conductive cover 4, heat insulating mattress 8 is arranged on heat conduction
Between the inner top surface of lid 4 and the top surface of Kick type temperature controller 1 with drag hook, the Kick type temperature controller 1 with drag hook passes through inner support 3
Fixed, thermistor 2 is close to the inner top surface of conductive cover 4.
The present invention is by adding heat insulating mattress 8, such conductive cover 4 between the Kick type temperature controller in conductive cover and with drag hook
The heat absorbed is largely reduced by heat transfer by the part that the Kick type temperature controller 1 with drag hook absorbs, so as to reduce pair
The influence of the temperature at the measurement inner vessel for electrical cooking-vessel of thermistor 2 bottom, improves the sensitivity of thermistor 2；And due to electric cooker mistake
Heat heating is relatively slow process, relatively low to the sensitivity requirement of the Kick type temperature controller 1 with drag hook as protection element.
As preferred embodiment, heat insulating mattress 8 is circular ring type packing ring, and the internal perisporium lower end of annular packing ring is provided with groove
81, as shown in Figure 2.The heat insulating mattress 8 of this spline structure, can pass through groove 81 and the aluminium lid 11 of the Kick type temperature controller 1 with drag hook
It is engaged by clamping, while convenient for assembly, can prevents heat insulating mattress 8 from shifting, influences the firm of the Kick type temperature controller 1 with drag hook.
