Title: Electronic warning device with scent dispersion mechanism

Description:
FIELD OF THE INVENTION 
     The present invention relates to an electronic warning device with scent dispersion mechanism, and more particularly, to an electronic element having at least two scent sources disposed there at that is able to emit a scent as a warning signal when the electronic element is operating abnormally. 
     BACKGROUND OF THE INVENTION 
     With rapid advance of technology, networks as well as networking devices are becoming common and essential in our daily life, not to mention that they are generally required to be operating 24 hours, seven days, all year round. Consequently, electronic components that are built inside those network devices should be design to function in a high-temperature environment. However, if there is no device to monitor and control the working temperatures of those electronic components for networking, they can crash and burn easily due to overheat. Therefore, for every network, it is important to have some sort of temperature monitor built therein. 
     There are two types of temperature monitors that are currently available on the market, which are the visual indicators, such as LED indicators, and the alarm devices, such as a buzzer, and both of which are capable of issuing a warning signal to a user for reminding the user that the working temperature of the electronic component it is monitoring had reached a predefined threshold. However, the warning signals from those two conventional temperature monitors may not be very effective and can sometimes be ignored by careless users. Therefore, it is in need of an improved warning device capable issuing a warning signal different from those visual signals and audio signals. 
     SUMMARY OF THE INVENTION 
     In view of the disadvantages of prior art, the primary object of the present invention is to provide an electronic warning device with scent dispersion mechanism, which comprises: an electronic element; and at least two scent sources, featured with different vaporization temperatures while being disposed simultaneously on the electronic element. In this embodiment, there are two scent sources, i.e. a first scent source that can be vaporized at a first vaporization temperature, and a second scent source that can be vaporized at a second vaporization temperature, whereas the second vaporization temperature is higher than the first vaporization temperature. Thereby, operationally, when the temperature of the electronic element that is operating normally and reaches the first vaporization temperature, the first scent source is vaporized, but when the electronic element is operating abnormally for causing the temperature of the electronic element to be raised to a temperature higher than the second vaporization temperature, the second scent source is vaporized to be detected by users as a warning signal. 
     Another object of the invention is to provide an electronic element having three scent sources disposed there at, i.e. a first scent source, a second scent source and a third scent source, while allowing the first scent source to be vaporized at a first vaporization temperature, the second scent source to be vaporized at a second vaporization temperature, and the third scent source to be vaporized at a third vaporization temperature; wherein the third vaporization temperature is higher than the second vaporization temperature while the second vaporization temperature is higher than the first vaporization temperature; and operationally, when the temperature of the electronic element that is operating normally and reaches the first vaporization temperature, the first scent source is vaporized, and when the electronic element is operating abnormally for causing the temperature of the electronic element to be raised to a temperature higher than the second vaporization temperature but still lower than the third vaporization temperature, the second scent source is vaporized to be detected by users as a mild warning signal, but when the electronic element is operating abnormally for causing the temperature of the electronic element to be raised to a temperature higher than the third vaporization temperature, the third scent source is vaporized to be detected by users as a severe warning signal. 
     To achieve the above objects, the present invention provides an electronic warning device with scent dispersion mechanism, which comprises:
         a housing, having a plurality of heat dissipation holes formed there at;   a printed circuit board;   a heat-generating electronic element, disposed on the printed circuit board;   a first scent source, attached to the heat-generating electronic element, capable of being vaporized at a first vaporization temperature; and   a second scent source, attached to the heat-generating electronic element, capable of being vaporized at a second vaporization temperature that is higher than the first vaporization temperature;   wherein, both the vaporized first and second scent sources are allowed to dissipate and discharge through the plural heat dissipation holes.       

     Preferably, the electronic warning device with scent dispersion mechanism is a device selected from the group consisting of: a network device, and a fixed communication equipment. 
     Preferably, the heat-generating electronic element is a component selected from the group consisting of: a micro control unit, a central process unit, a chip module and a power module.
