Abstract
The utility model relates to the daily life article technical field, more particularly an electronic thermometer sensing head structure which comprises a NTC thermal resistance, two conducting wires and a metal outer sleeve; wherein, one end of the conducting wire is connected with the NTC thermal resistance, and the other end of the conducting wire is connected with a circuit board in a thermometer body. The NTC thermal resistance is provided in the metal outer sleeve. The metal outer sleeve is connected with one end of the thermometer body. An internal cavity of the metal outer sleeve is filled with a fixing material of a heat poor thermo-conductor. The fixing material presses the NTC thermal resistance and the two conducting wires against the internal wall of the metal outer sleeve. When the body temperature is measured, the NTC thermal resistance and the conducting wires are heated at the same time, which reduces the temperature difference between the NTC thermal resistance and the conducting wires, avoids unnecessary heat loss and speeds up the measurement of temperature.
Description
Technical field:
The utility model relates to the daily living article technical field, refers in particular to a kind of electronic thermometer sensing head structure.
Background technology:
Clinical thermometer is as the apparatus that is used to measure human body temperature in a kind of people's daily life, roughly have two kinds at present: a kind of is the liquid clinical thermometer, it is that volume change is measured human body temperature by heated liquid, this clinical thermometer with after can not restore rapidly, it is not too convenient to use.Another kind is an electronic thermometer, and it is to come the sensing human body temperature by thermistor, by call wire the temperature that senses is transferred to corresponding electronic component subsequently and shows.But existing electronic thermometer, because connecting the call wire of thermistor does not contact with the metal-coating of sensing head, the human heat does not only heat to call wire to the thermistor heating during thermometric, cause the excessive temperature differentials between call wire and the thermistor thus, can take away the heat of thermistor when call wire conducts heat, the time of thermometric is longer.
Summary of the invention:
The purpose of this utility model is to provide a kind of thermistor and call wire to obtain heating simultaneously, can accelerate the electronic thermometer sensing head structure of thermometric speed, and it is simple in structure, and is easy to assembly.
The utility model is achieved by the following technical solution: the metal-coating inner chamber of sensing head is filled with athermanous immobilization material, and this immobilization material pressure holding NTC thermistor and two call wires are on the inwall of metal-coating; The top in described NTC thermistor pressurized chamber within metal-coating, and two call wires can separately overlay the inwall in metal-coating, also can be close to be set together.
Described NTC thermistor, call wire and immobilization material can be pasted on the metal-coating inwall with viscose glue.
The utility model adopts the immobilization material of hot poor conductor to push down NTC thermistor and call wire, it is close on the metal-coating inwall, thus when take temperature, NTC thermistor and call wire be heat temperature raising simultaneously, reduce the temperature difference between NTC thermistor and the call wire, avoid unnecessary thermal loss, accelerated thermometric speed.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the sensing head of the utility model;
Accompanying drawing 3 is the structural representation of another embodiment of sensing head.
Embodiment:
See accompanying drawing 1,2,3, the utility model includes NTC thermistor 1, two call wires 2 and metal-coating 3.Call wire 2 one ends are connected with NTC thermistor 1, and the other end is connected on the circuit board 6 in the clinical thermometer body 5, and NTC thermistor 1 is arranged in the metal-coating 3, and metal-coating 3 is connected in an end of clinical thermometer body 5.Metal-coating 3 inner chambers are filled with the immobilization material 4 of hot poor conductor, and immobilization material 4 pressure holding NTC thermistors 1 and two call wires 2 are on the inwall of metal-coating 3.The top in NTC thermistor 1 pressurized chamber within metal-coating 3, and two call wires 2 can separately overlay in the inwall of metal-coating 3, also can be close to be set together.When actual assembled, NTC thermistor 1, call wire 2 and immobilization material 4 can be pasted on metal-coating 3 inwalls with viscose glue.
During use, sensing head of the present utility model is inserted thermometric positions such as oral cavity or oxter, metal-coating 3, NTC thermistor 1 and call wire 2 are subjected to the heat heat temperature raising of human body simultaneously, thereby the surrounding environment temperature difference of NTC thermistor 1 is little, so that the temperature increase of NTC thermistor 1 is accelerated, and shortening of thermometric time and accuracy rate are higher.Call wire 2 of the present utility model is close to the inwall of metal-coating 3, also obtain human heat's heating during thermometric, reduced it and taken away the heat of NTC thermistor 1, immobilization material 4 is the poor conductor of heat simultaneously, thereby avoid unnecessary thermal loss, accelerated thermometric speed.
