Abstract
The utility model relates to an ammeter-type thermometer including a working power supply, and a thermistor, a first amplifier, an adjuster and a display ammeter, which are electrically connected in order, wherein the first amplifier is electrically connected with the working power supply. The ammeter-type thermometer displays a temperature value through adoption of the display ammeter so that the value can be read directly and a defect that value reading of common thermometers is difficult is overcome.
Description
Technical field
The utility model relates to a kind of thermometer, is specifically related to a kind of ammeter type clinical thermometer.
Background technology
At present, the clinical thermometer of middle and primary schools' use for laboratory is all the mercury clinical thermometer of glass tube encapsulation, and kind is single, and student's reading difficulty, the needs that be out of step with the times far away development and new textbook reform change.
Summary of the invention
For the problems referred to above, the utility model provides a kind of ammeter type clinical thermometer, can draw intuitively Temperature numerical.
Ammeter type thermometer described in the utility model, comprise working power and the temperature sensing device, signal output system and the demonstration ammeter that are electrically connected to successively, and working power wherein is connected with signal system.
Preferably, ammeter type thermometer described in the utility model, temperature sensing device wherein is thermistor.
Perhaps preferably, ammeter type thermometer described in the utility model, first amplifier and the regulator of signal output system wherein for being electrically connected to, the first amplifier also is electrically connected to working power.
More preferably, ammeter type thermometer described in the utility model, also comprise the comparer, the second amplifier, time base circuit, music-integrating block and the loudspeaker that are electrically connected to successively, wherein comparer also is electrically connected to the demonstration ammeter, and the second amplifier is also connecting working power.
Perhaps more preferably, ammeter type thermometer described in the utility model, also comprise the comparer, the second amplifier, time base circuit and the hummer that are electrically connected to successively, and wherein comparer also is electrically connected to the demonstration ammeter, and the second amplifier is also connecting working power.
The ammeter type thermometer that the utility model provides, adopted the demonstration ammeter to show, obtains out Temperature numerical intuitively, overcomes the defect of temperature reading difficulty commonly used.
In the arranging of preferred embodiment, when people's body temperature surpasses 38 functions that can also send musical sound or buzzer while spending, interesting and science are melted into a whole, be beneficial to very much classroom instruction, can also be for resident family or hospital doctor use.

Embodiment
A kind of ammeter type clinical thermometer, comprise thermistor 1, the first amplifier 2, the regulator 3 be electrically connected to successively and show ammeter 4.
Principle of work: with thermistor (temperature) sensor, do probe, the resistance of thermistor is along with changing (reducing) when temperature variation (rising), when thermistor is sensed the temperature reduction, the resistance of thermistor increases on the contrary, its change in resistance of thermistor place in circuit is caused in circuit to size of current or voltage just change, this faint change information accesses the first amplifier, obtain certain strength of current by the first amplifier, through regulator, proofread and correct by showing that ammeter demonstrates numerical value, the numerical value that demonstration meter pointer wherein shows is corresponding with body temperature, write out the body temperature value by the table of comparisons.
A kind of ammeter type clinical thermometer, comprise working power and the thermistor 1 be electrically connected to successively, the first amplifier 2, regulator 3, show ammeter 4, comparer 5, the second amplifier 6, time base circuit 8, music-integrating block 9 and loudspeaker 10, the second amplifier 6 wherein also is connected with the first amplifier 1 by working power 7.
A kind of ammeter type clinical thermometer, comprise working power and the thermistor 1 be electrically connected to successively, the first amplifier 1, regulator 3, show ammeter 4, comparer 5, the second amplifier 6, time base circuit 8 and hummer 11, the second amplifier 6 wherein also is connected with the first amplifier 2 by working power.
Principle of work: with thermistor (temperature) sensor, do probe, the resistance of thermistor is along with changing (reducing) when temperature variation (rising), when thermistor is sensed the temperature reduction, the resistance of thermistor increases on the contrary, its change in resistance of thermistor place in circuit is caused in circuit to size of current or voltage just change, this faint change information accesses the first amplifier, obtain certain strength of current by the first amplifier, through regulator, proofread and correct by showing that ammeter demonstrates numerical value, the numerical value that demonstration meter pointer wherein shows is corresponding with body temperature, write out the body temperature value by the table of comparisons, and then the numerical information of strength of current is sent to comparer, when ammeter is shown to more than 38 ℃ and 38 ℃, by the second amplifier, signal is amplified, make time base circuit work, starting music-integrating block work allows loudspeaker send certain musical sound, perhaps time base circuit startup hummer is sounded a buzzer.
The using method of ammeter type thermometer described in the utility model is: when measuring people's body temperature, the probe lead wire plug of thermistor inserts in the probe insertion on " ammeter type thermometer " panel, can be placed on the palm of the hand to thermistor probe, open the power switch of " ammeter type thermometer ", watch human body palm of the hand temperature value (the body temperature value than the people is on the low side), the position that thermistor probe is placed on to normal measurement body temperature is measured, show people's body temperature value in showing ammeter, very directly perceived, easy to use, musical sounding can be placed on probe in the warm water over the human normal value, surpass 38 ℃ and can send musical sound.
