ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an infrared temperature wave guide device.
(b) Description of the Prior Art
Relatively advanced temperature sensing apparatuses, such as pistol-shaped ear temperature sensors, generally have a temperature sensing means disposed in a measuring end. The sensing means can measure temperatures in contact and non-contact manners. The principle employed thereby is mainly to induce the infrared radiation generated by the temperature of the source to be measured, to compare by means of an infrared temperature sensing element and thermistor, and to convert the measured temperature output into digital displays. A major disadvantage is that the housing of the above-mentioned apparatus is generally in the form of a tube made of metal, which is relatively heavy, costly, and bulky. Besides, its oxidation-proof effect is poor; the infrared temperature sensing element cannot be replaced at will; the speed of sensing and measuring is slow, etc.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide an infrared temperature wave guide device that is light and compact, and that has longer service life and preferred anti-oxidation capability, and that is easy to process.
Another object of the present invention is to provide an infrared temperature wave guide device that can prevent entry of dusts therein.
A further object of the present invention is to provide an infrared temperature wave guide device that can accommodate a thermopile of different brands and different models.
In order to achieve the above-mentioned objects, an infrared temperature wave guide device of the present invention includes a wave guide tube, a housing accommodating a thermopile, a thermistor, and a circuit board, and a rear cap for securing purposes. A front end of the wave guide tube is provided with a cover to prevent entry of dusts. The housing and rear cap are formed from plastic material. The connection of the housing and the rear cap is suitably adjustable to allow mounting of different thermopiles.
The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
