     DETAILED DESCRIPTION OF THE INVENTION  
       [0021]    Referring to FIG. 1 and FIG. 2, FIG. 1 is a block diagram schematically showing a structure of a wrist time device with function of environmental status detecting/informing in accordance with a preferred embodiment of present invention, and FIG. 2 is a schematic view showing a product made in accordance with the preferred embodiment of the present invention, respectively. The wrist time device  1  comprises a case  10 , which contains a control circuit unit  11 ; a display unit  12 ; a memory unit  13 ; an input unit  14 ; a timer unit  15 ; a battery  16 ; a gases/molecules detection unit  17 ; and a spectra identification unit  18 .  
         [0022]    As shown in the figures, the control circuit unit  11  operates to process data and time as well as to control the operation of each member. The memory unit  13  pre-stores the spectra of specific gases/molecules such as volatile organic gas (VOCs), gas, marsh gas, methane (CH 4 ), hydrochloride (HCl), chlorine (Cl 2 ), carbon oxide (CO), hydrosulfur (H 2 S), sulfate (H 2 SO 4 ), oxynitride (NO x ), Dioxin, and at least one substance selected from a group of similar materials. The input unit  14  allows the user to input a control signal to the control circuit unit  11  via a control button  20 , so that the control circuit unit  11  may operate to process the data, to display the time and to control the operation of each member in accordance with the selected mode confirmed by a select button  19 . Furthermore, except directly inputting an instruction or command via the control button  20  and select button  19  of the input unit  14 , the user may also use a transmitting interface unit, which is capable of performing bidirectional data transmission and connected to other devices such as personal computer (PC), personal data assistant (PDA) and the like to perform further data analysis and storage.  
         [0023]    The display unit  12  is a display, such as liquid crystal display, used to display time and data through the control of said control circuit unit  11  via the select button  19 . The timer  15  provides time and elapse time on the display unit  12  through the control circuit unit  11 . The battery  16  supplies working voltage to each member so as to conduct the corresponding function.  
         [0024]    According to the present invention, the wrist time device  1  comprises a micro gases/molecules detection unit  17  for performing real-time detection of gases/molecules flew in from the surrounding, that is to say, it is possible to detect ultra minute amount (e.g., ppm) of sample gas by means of a direct-read detector.  
         [0025]    However, the present invention is not limited to above sampling method but can also be an absorptive sampling method, in which an IC chip of detection unit operates to generate various current when there are gases/molecules flew in from the surrounding, and then transforms such current into the spectra of the gases/molecules by means of a Fourrier transform infrared (FTIR) interferometer or an differential optical absorptive spectroscopy (DOAS) of prior art. Subsequently, the spectra identification unit  18  identifies the spectra based on the pre-stored spectra of specific gases/molecules and displays data such as the name and concentration of the specific gases/molecules on the display unit  12  whenever there is a match. Optionally, the concentration can be expressed as a detection mode of elapse time and displayed correspondingly.  
         [0026]    Besides, the wrist time device further comprises a put-on device  21  such as watchband, necklace and the like. An example of watchband is shown in FIG. 2; however, the present invention is not limited to this.  
         [0027]    [0027]FIG. 3 is a flow chart showing the operation process of the preferred embodiment of the present invention, in which only the operation of the wrist time device with function of environmental status detecting/informing is included, the operation of timer is familiar to those skilled in prior art and will be omitted. Initially, the micro gases/molecules detection unit  17  of the wrist time device  1  detects gases/molecules in the surrounding area in step S 1 ; generates the spectra of detected gases/molecules based on the concentration or current of the detected gases/molecules in step S 2 ; then identifies the spectra of detected gases/molecules based on the spectra of specific gases/molecules pre-stored in the memory unit  13  in step S 3 ; and subsequently determines whether there is a match in step S 4 , if there is no match, the procedure returns to step S 1 , while if there is a match, the procedure proceeds to step S 5 ; displays the name and concentration of the identified gases/molecules on the display unit  12  in step S 5 ; the beeper is activated for alerting when the concentration of said gases/molecules is higher than a pre-determined level until the reset key (denoted as  22  in FIG. 2) is pressed by the user; finally, the procedure again returns to step S 1  to start another detecting/informing operation.  
         [0028]    As described above, since there are deleterious gases/molecules and allergic elements (e.g., some specific gases/molecules) everywhere in the surroundings, it is advantageous that a wrist time device with function of environmental status detecting/ informing in accordance with present invention provides the safe and healthy protection of a user from deleterious gases/molecules in the environment, in which the micro gases/molecules detection unit will be activated by the surrounding gases/molecules flew into the wrist time device, while an IC chip of said detector operates to generate various current and transform such current into the spectra of said gases/molecules based on the variation of voltage supplied thereon by applying a bias, a spectra identification unit will then identify the spectra based on the pre-stored spectra of specific gases/molecules and display data such as the name and concentration of the specific gases/molecules whenever there is a match and activate a beeper to warn the user of the existence of deleterious gases/molecules.  
         [0029]    However, above described is a preferred embodiment of present invention. Those who skilled in prior technique should understand that present invention is not limited to above description and various modifications and changes in accordance with claims given below are considered to fall within the spirit and scope of present invention.
