Description
The utility model relates to a kind of measurement of bldy temperature meter, particularly a kind of ear thermometer that is used for take temperature.
At present, traditional employed ear thermometer must be measured body temperature by shutter (ON/OFF gate fast), and be calculated its mean value, because of it does not consider that temperature has the situation of forfeiture in the measurement process, so measure body temperature not accurate enough.
Fundamental purpose of the present utility model is to provide a kind of measurement ear thermometer accurately, its by repeatedly instantaneous measurement different numerical value and get its mean value, can obtain body temperature value comparatively accurately.
For the utility model that achieves the above object is taked following measure: ear thermometer of the present utility model includes: an ear thermometer body, a circuit board and temperature detector; The ear thermometer body has a Handheld Division and a head, establishes a power switch and display on the Handheld Division, and the head back side is provided with a thermometric switch; Circuit board is located at body interior, and temperature detector connects in circuit board;
It is characterized in that: circuit board is vertically is located at the ear thermometer body interior, extends two temperature detectors on the circuit board respectively; One cylindrical hollow metal piece is set on the ear thermometer, the derby end can bind with circuit board and be one, the outside screw thread that forms of derby, derby inside sets firmly the waveguide pipe of a hollow, waveguide pipe interfixes with its terminal inside with derby, one temperature detector is located at the terminal central authorities of waveguide pipe, and another temperature detector and derby are in contact with one another conducting, and the derby outside screws togather a shell.
Described ear thermometer is characterized in that: described waveguide pipe inboard is provided with minute surface, and the waveguide pipe medial and lateral have Gold plated Layer respectively, so that the waveguide pipe surface forms shiny surface.
Described ear thermometer is characterized in that: be formed with the gap between described shell, derby and waveguide pipe.
Compared with prior art, the utlity model has following effect: because the utility model is when measuring body temperature,, and get its mean value,, calculate the body temperature value by the infinitesimal analysis principle by measured different numerical value of moment different time repeatedly, comparatively accurate.
Because this ear thermometer is provided with the hollow metal piece, the derby end can bind with circuit board and be one, derby inside sets firmly the waveguide pipe of a hollow, waveguide pipe interfixes with its terminal inside with derby, one temperature detector is located at the terminal central authorities of waveguide pipe, another temperature detector and derby are in contact with one another conducting, and the derby outside screws togather a shell; Be formed with the gap between shell, derby and waveguide pipe.Because the waveguide pipe inboard is provided with minute surface, and the waveguide pipe medial and lateral have Gold plated Layer respectively, make the heat shiny surface of body temperature formation again.Therefore, the heat at ear thermometer place is difficult for losing because of heat conduction and heat radiation, to obtain body temperature value accurately.
Further specify specific structural features of the present utility model below in conjunction with drawings and Examples.

Fig. 3 is a broken section enlarged drawing of the present utility model.
Fig. 4 is the broken section enlarged drawing of preferred embodiment of the present utility model.
Fig. 5 is the circuit diagram of embodiment of the present utility model.
As shown in Figure 1 and Figure 2, ear thermometer of the present utility model comprises: an ear thermometer body 10, and it comprises a Handheld Division 11 and a head 12, Handheld Division 11 is provided with a power switch 13, when people push this switch 13, can control the unlatching of power supply or closes; One display 15 can show that the user can carry out ear temperature state quantity measurement and measured temperature, and the place, the back side of head 12 is provided with a thermometric switch 14 (as shown in Figure 3).
Topmost characteristics of the present utility model are: the inside of ear thermometer body 10 vertically is provided with a circuit board 20, extends two temperature detectors 21,22 on the circuit board 20 respectively; One cylindrical hollow metal piece 30 is set on the ear thermometer body 10, the terminal part of derby 30 is can bind mutually with circuit board 20 to be one, and be formed with screw thread 31 in the outside of derby 30, derby 30 inside can set firmly the waveguide pipe 40 of a hollow, there is minute surface the inboard of waveguide pipe 40, and the medial and lateral of waveguide pipe 40 have gold-plated respectively, can make waveguide pipe 40 surfaces form shiny surface, so that temperature can conduct to temperature detector 22 places that are positioned at waveguide pipe 40 terminal central authorities fast, another temperature detector 21 is to be in contact with one another conducting with derby 30; The outside of derby 30 is the shells 50 that can screw togather a nonmetal hollow of making, the main effect of shell 50 is isolated ambient temperatures, so that ambient temperature can not influence the temperature of 30 of waveguide pipe 40 and derbies fast, shell 50 is can stretch in people's the ear 60 (as shown in Figure 4), in order to measure user's body temperature when using.
Be formed with the gap between shell 50, derby 30 and 40 of waveguide pipe, to avoid producing mutual heat conduction influence therebetween, and 30 of waveguide pipe 40 and derbies are to fix with the end of waveguide pipe 40, so that the temperature in the waveguide pipe 40 only can be conducted to derby 30 by the end of waveguide pipe 40.
During use, waveguide pipe 40 and derby 30 all are in room temperature state (as shown in Figure 4), after starting power switch 13, temperature detector 21 can measure derby 30 the first time temperature that is the amount room temperature) and get its value, after waiting for five seconds again, derby 30 can be risen again, this moment, display 15 can show that promptly can carry out the ear temperature measures, when pushing thermometric switch 14 and shell 50 being stretched in the ear, temperature detector 21 promptly can be measured the temperature second time of derby 30, every several seconds zero point after, temperature detector 21 can be surveyed the temperature for the third time of derby 30 again, wherein when measuring second of derby 30, three temperature are the amplitudes that rise and change for the relative temperature after the time change; The temperature that the measurement waveguide pipe that while temperature detector 22 can (utilize power supply control) fast is 40 4 times, it mainly is an observable temperature descend (amplitude of change) when changing for the survey time, and desirable its mean value, temperature detector 21 can be surveyed the 4th temperature of derby 30 more then, wherein when measuring second of derby 30, three, four temperature are the amplitudes that rise and change for the relative temperature after the time change, last will add that the temperature (being the ascending temperature of derby 30) of forfeiture adds room temperature and be the actual temperature that should be recorded that is be the most realistic body temperature value of people by the ascending temperature that records in the waveguide pipe 40 (i.e. the temperature that rises by room temperature) again, and can be by showing in the display 15.
As shown in Figure 5, it is the circuit diagram of embodiment of the present utility model.Wherein expression has: microprocessor, temperature detector 21,22, power switch 13, thermometric switch 14 and display 15 etc.; More than each time temperature measurement, keep in mind, calculating etc. all finished by the microprocessor in the circuit board 20 and each electronic component, this partly because of non-be emphasis of the present utility model, so do not repeat them here.
