Abstract
A temp. measuring structure for clinical ear thermometer for shortening the distance from temp. detector to temp-sampling opening is disclosed.Said clinical ear thermometer is composed of main body, control circuit board containing converter from detected body temp to digitals and wave guide device at one side of the main body. Said control circuit board also contains a temp. detector in ear temp tract of wave guide device. The internal diameter of ear temp. tract is gradually reducd to form a very good focuse of thermal waves. A slot for installing protective sleeve of temp detector is made at periphery of ear temp contract.
Description
The present invention relates to a kind of temperature sensing structure of ear temperature meter.
Present ear temperature meter, focus on purpose fast for reaching heat wave, in the ear temperature tract 10 of wave guide 1, be provided with a copper waveguide pipe 11 (as shown in Figures 1 and 2), this copper waveguide pipe 11 is longer than ear temperature tract 10, and extend inward in the ear temperature meter body, 13 inboards of being located at copper waveguide pipe 11 of Temperature Detector promptly are located in the body 14.Its shortcoming is that this Temperature Detector 13 can be because of the setting of copper waveguide pipe, and it is too far away apart from d to make Temperature Detector 13 and copper waveguide pipe obtain 100 of the temperature taking mouths of the ear temperature tract 10 of temperature in the ear, thereby make and take from the interior heat wave of ear, need to be measured by Temperature Detector apart from d through long, cause heat wave loss therebetween extremely many, influence the accuracy that clinical thermometer is measured.
In addition, the waveguide pipe of flat all is same inner diameter from head end to end, can't reach the effect of real focusing, the fault rate height that clinical thermometer is measured.
The purpose of this invention is to provide a kind of distance that shortens temperature taking mouth to Temperature Detector, so that clinical thermometer is measured the temperature sensing structure of ear temperature meter more accurately.
The present invention is achieved in that it includes body and wave guide; It is characterized in that: wherein Temperature Detector is located at the ear temperature tract inboard of wave guide, and temperature taking mouth is shortened to the distance between Temperature Detector, and temperature makes the clinical thermometer detection more accurate rapidly for Temperature Detector records in the human body ear that temperature taking mouth obtains in ear thereby make.
Wherein this wave guide inboard is provided with Temperature Detector, and this wave guide also is provided with ear temperature tract, and the internal diameter of this ear temperature tract is outer greatly inwardly gradually little shape, to form the ear temperature tract as toroidal, to reach preferable heat wave focusing function.
Wherein the ear temperature tract of this wave guide is provided with the engagement groove of sheath, and the interior ring that the shape of this engagement groove can be provided with for the sheath setting encloses, with the protection Temperature Detector.
Characteristics of the present invention are to be provided with Temperature Detector in the wave guide inboard, and this wave guide is provided with ear temperature tract, and the internal diameter of this ear temperature tract is outer greatly inwardly gradually little shape, to form the ear temperature tract of similar hydraucone shape, to reach preferable heat wave focusing function.
Another characteristics of the present invention are that Temperature Detector is the ear temperature tract inboard of being located at wave guide, have and shorten the advantage of temperature taking mouth to distance between Temperature Detector, make that temperature is rapidly for Temperature Detector records in the human body ear that temperature taking mouth obtains in ear, it is more accurate that clinical thermometer is detected.
Another characteristics of the present invention are: the ear temperature tract front side at wave guide also is provided with sheath, is not covered with dust with the protection Temperature Detector, guarantees working properly.
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 is the existing product phantom view.
Fig. 2 is the wave guide cut-open view of existing product.
Fig. 3 is wave guide embodiment one cut-open view of the present invention.
Fig. 4 is the front cross-sectional view of Fig. 3.
Fig. 5 is wave guide embodiment two cut-open views of the present invention.
Fig. 6 is the front cross-sectional view of Fig. 5.
As Fig. 3 and shown in Figure 5, ear temperature meter of the present invention includes body 2, and this body 2 is provided with certainly becomes the indispensable parts of ear temperature meter, but because of non-genus the present invention improves element, does not repeat them here.
Ear temperature meter of the present invention is provided with wave guide 3, this wave guide 3 has suitable external diameter, be beneficial to this wave guide 3 plug establish pleasant in, to obtain human body temperature in the ear, and wave guide 3 is provided with the containing groove 30 of Temperature Detector 4, and this containing groove 30 is be positioned at ear temperature tract 31 the most inboard, for Temperature Detector is set, shorten the distance D of temperature taking mouth 32 with the Temperature Detector 4 of ear temperature tract, improve the accuracy of temperature detection.In addition, the internal diameter of ear temperature tract is in the position of temperature taking mouth maximum, but more toward in then more little, make the internal diameter of ear temperature tract be bell mouth shape, its advantage is that temperature taking mouth can be obtained heat wave in the more ear, and this heat wave dwindles shape from the ear temperature tract temperature taking mouth gradually to being Temperature Detector, and produce suitable good focusing function, thus make the present invention not only get temperature distance weak point, good because of the heat wave focusing effect again, make heat wave in a large number for Temperature Detector records, and make the detection of clinical thermometer more accurate.
Secondly; for the Temperature Detector that prevents high-accuracy design is subjected to being infected with of dust; and lose accuracy; be provided with the engagement groove 33 of sheath 5 at the ear temperature tract 31 of wave guide 3; the shape of this engagement groove 33 can enclose 330 for sheath is set as the set interior ring of Fig. 4; reach the purpose of protection Temperature Detector, guarantee that Temperature Detector is working properly.
In sum, the present invention not only can shorten temperature taking mouth to the temperature between the Temperature Detector, to reduce the heat wave loss, more because of ear temperature tract has good heat wave focusing function, can improve the accuracy of measurement of bldy temperature.
