To achieve these goals, this utility model adopts following structure:
It comprises shell and is located at the inside infrared survey parts of shell, described infrared survey parts connect a body temperature indicating device, its improvement is: described infrared survey parts comprise a wiring board, wiring board is provided with infrared ray sensor, described wiring board and infrared ray sensor are installed in the metal cylinder, described metal cylinder outside is provided with a probe bracket, the wiring board bottom is provided with fin, and described wiring board, infrared ray sensor and metal cylinder are located in the inner space of probe bracket and fin composition.
Preferably, in probe bracket, the metal cylinder top is provided with a filter lens.
Preferably, described shell comprises upper casing, lower casing and is positioned at upper casing and the cap at lower casing top that described lower casing is provided with battery compartment.
Preferably, also comprise first cushion rubber and second cushion rubber, first cushion rubber is installed between cap and the probe bracket; After installing, cushion rubber 2 is positioned on metal cylinder and the filter lens.
Preferably, described body temperature indicating device is a LED light, and LED light connection line plate shows different prompting colors to different temperature ranges.
Preferably, be provided with a critesistor in the described cap.
Contactless clinical thermometer of the present utility model is by in each a parts setting and a probe bracket with the infrared survey part, make the clinical thermometer internal structure simple and rationally stable, the parts that use are few, reduced cost, be convenient to large scale application, and in use Stability Analysis of Structures is reliable, has increased the service life of product.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the principle schematic of this utility model embodiment.
This utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
As shown in Figure 1, comprise shell and the inside infrared survey parts of being located at shell, described infrared survey parts connect a body temperature indicating device, described infrared survey parts comprise a wiring board 1,1 is provided with infrared ray sensor 2 on the wiring board, described wiring board 1 and infrared ray sensor 2 are installed in the metal cylinder 3, described metal cylinder 3 outsides are provided with a probe bracket 4, wiring board 1 bottom is provided with fin 5, and described wiring board 1, infrared ray sensor 2 and metal cylinder 3 are located in the inner space of probe bracket 4 and fin 5 compositions.This clinical thermometer circuit comprises infrared measurement of temperature circuit, AD testing circuit, temperature signal amplifying circuit and circuit such as signal processing and demonstration.Wherein:
The infrared measurement of temperature circuit: temperature and ambient temperature by infrared sensor induction targets object obtain correspondent voltage value and resistance value;
The AD testing circuit: 1, detect voltage and resistance value 2, the magnitude of voltage that obtains and resistance value carried out the AD analog-to-digital conversion handle;
The temperature signal amplifying circuit is that signal is carried out processing and amplifying, as electric current and voltage being amplified etc.:
After signal processing and display circuit: MCU transformed outside signal mode number, processing finally showed by display circuit through internal processes.
Infrared measurement of temperature circuit and AD testing circuit are detection means, and signal amplification circuit and signal processing are processing method, and the display part then is a display result, connects each other each other, and is indispensable.
In probe bracket 4, metal cylinder 3 inner and upper are provided with a filter lens 6, and filter lens 6 is generally a convex lens.
Described shell comprises upper casing 71, lower casing 72 and is positioned at upper casing 71 and the cap 73 at lower casing 72 tops that described lower casing 72 is provided with battery compartment 721.
Comprise that also first cushion rubber 81 and second cushion rubber, 82, the first cushion rubbers 81 are installed between cap 73 and the probe bracket; After installing, cushion rubber 82 is positioned on metal cylinder 3 and the filter lens 6.It is shockproof that two cushion rubbers mainly play sealing.
Be provided with a critesistor 9 in the described cap.The effect of critesistor mainly detects ambient temperature
Described body temperature indicating device is a LED light 10, and LED light 10 connection line plates show different prompting colors to different temperature ranges.In 36.3 ℃-37.3 ℃ (97.4-99.2) scopes, green light is bright as temperature; Temperature is in 37.4 ℃-37.9 ℃ (99.3-100.2) scopes, and amber light is bright; Temperature is when 〉=38.0 ℃ of (100.3) scopes, and orange lamp is bright }.
As shown in Figure 2, application principle: along with the increase of measured target object distance (D), it is big that the size (S) of regional luminous point that temperature measurer is surveyed becomes.Spot definition is represented 90% circle self-energy, when temperature measurer and target object distance is 100MM, with the big luminous point of generation 12.5MM, can obtain corresponding D:S value.Guarantee accurately to measure the target object actual temperature value, target object is greater than luminous point in size.Target is more little then should be near more from it.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes this utility model description and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
