Abstract
A temperature sensor used for temperature measuring in electronic water cooker belongs to a temperature test device of domestic appliances, especially used for measuring the water temperature in electronic water cooker.It is characterized in that it's a temperature sensor with thermistor of NTC negative temperature coefficient, the external structure of said temperature sensor body is the shape of bullet head, said thermistor of NTC negative temperature coefficient is arranged at the bullet head; A silica gel ring is arranged at the joined parts of said temperature sensor body; A sensor pressing piece is arranged under the said temperature sensor body. This utility model adopts the assembly manner of directly contacting with water, can reach the high accuracy when measuring temperature and temperature error is at the range of +/-3 DEG C, and meet the requirement of temperature measurement, guaranting the nomal opertion of electronic water cooker.
Description
Technical field:
The utility model relates to a kind of electronics water thermometric temperature sensor of stewing that is used for, and it belongs to a temperature test device in the household electrical appliance, is used in particular for the thermometric proving installation of water in electronics water pot.
Background technology:
The existing reason that is used for the thermometric sensor of electronics water pot owing to structural design, after on the heat-generating disc that it is installed on electronics water pot, in use owing to the heat transferred that can occur between sensor and the heat-generating disc rapidly, temperature rises too fastly, can directly have influence on the sensitivity and the accuracy of sensor.Because the inaccurate row of this temperature transfer will bring very big influence to the operate as normal of electronics water pot.
Summary of the invention:
The purpose of this utility model is to provide a kind of sensitivity good, and that can transmit temperature information exactly is used for the electronics water thermometric temperature sensor of stewing.
The purpose of this utility model is achieved in that
A kind of electronics water thermometric temperature sensor of stewing that is used for, it is characterized in that it is a temperature sensor that has the thermistor of NTC negative temperature coefficient, the external structure of described temperature sensor body is the shape of sub warhead, and the thermistor of described NTC negative temperature coefficient is arranged on the end of the sub warhead of sensor; Link at described temperature sensor body is provided with a silica gel circle; Below described temperature sensor body, be provided with a sensor compressing tablet.
Be provided with the ring of a projection at the outside surface of the link of described temperature sensor body, described silica gel circle is stuck on the ring of described projection.
Outside surface at described silica gel circle is provided with draw-in groove.
Described sensor compressing tablet is a metal sheeting.
The utility model can directly touch the fit of water, can reach the higher accuracy of measuring temperature, the temperature error of being tested has reduced measuring error to greatest extent at ± 3 ℃, can the satisfied temperature Testing requirement, guaranteed the normal use of electronics water pot.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the utility model temperature sensor main body structure synoptic diagram
Accompanying drawing 3 is an installment state structural representation of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3 below, the utility model be further detailed:
It is a temperature sensor that has the thermistor of NTC negative temperature coefficient for the utility model, the external structure of described temperature sensor body 2 is the shape of sub warhead, and the thermistor of described NTC negative temperature coefficient is arranged on the end of the sub warhead of sensor; Link at described temperature sensor body 2 is provided with a silica gel circle 3, and such structure not only has the function of sealing, can prevent liquid immersion outside container, thereby has influence on the function and the security performance of electrical equipment, the requirement that does not reach safety standard.Outside surface at described silica gel circle 3 is provided with draw-in groove 9, utilizes this draw-in groove 9, can the fixed temperature sensor body 2 with the position of heat-generating disc 1; Below described temperature sensor body 2, be provided with a sensor compressing tablet 5, and temperature sensor body 2 and sensor compressing tablet 5 are tightly pinned with screw 6 and screw column 4, make temperature sensor body 2 when contacting with liquid, can directly feel variation of temperature, the thermistor of the NTC negative temperature coefficient at sensor body top can be measured the temperature variations of water outlet accurately, and the error of measuring is little.For guarantee temperature sensor body 2 and silica gel circle 3 directly assembling firmly be provided with the ring 8 of a projection at the outside surface of the link of described temperature sensor body 2, described silica gel circle 3 is stuck on the ring 8 of described projection.Described sensor compressing tablet 5 is a metal sheeting, has better heat transfer effect.Described sensor compressing tablet 5 can use screw 4,6 to be fixed on the heat-generating disc 1.7 for connecting electric wire.
The thermistor of the NTC negative temperature coefficient that the utility model adopted, the thermistor of this specific character can change the resistance value of self because of the variation of ambient temperature.Utilize this temperature and changes in resistance property list to design electronic circuit, go to control the temperature of electronics water pot.Will guarantee when mounted that front end of the present utility model has about 5～10mm can immerse in the water, directly touches the water surface, has so just further improved the sensitivity of circuit and the accuracy of temperature.Thereby make the temperature error of measuring little.
