Title: Mouse device with ultraviolet for disinfection

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a mouse device, particularly to a mouse device with ultraviolet and photocatalyst for disinfection. 
     2. Description of the Related Art 
     Computers often have been used as working platforms for working and learning process, etc. After a user operates a mouse manually for a long time, the bacteria, which harms to human body, is propagated from the mouse. Thus, it is not very sanitary to use the mouse. Usually, the mouse is cleaned with alcohol or water. But this way is not very convenient and does not maintain hygiene of the mouse at any time. 
     In view of the problems and shortcomings of the prior art, the present invention provides a mouse device with ultraviolet for disinfection, so as to solve the afore-mentioned problems of the prior art. 
     SUMMARY OF THE INVENTION 
     A primary objective of the present invention is to provide a mouse device with ultraviolet for disinfection, which directs ultraviolet emitted from a lighting object disposed on the mouse to spread by a light directing layer disposed on the mouse device, and then the disinfection effect is achieved. 
     To achieve the abovementioned objective, the present invention provides a mouse device with ultraviolet for disinfection, which comprises a mouse device, a light directing layer disposed on an outer surface of the mouse device, and at least one lighting object disposed on the light directing layer and emitting ultraviolet rays outwardly by utilizing a power source applied by the mouse device, wherein ultraviolet is directed by the light directing layer to spread on the outer surface of the mouse device uniformly, and then the disinfection effect is achieved. Besides, a photocatalyst layer is disposed above the light directing layer, whereby ultraviolet interacts with the light directing layer, so as to enhance the ability of disinfection and bacteriostasis. 
     Below, the embodiments are described in detail in cooperation with the drawings to make easily understood the characteristics, technical contents and accomplishments of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Refer to  FIG. 1  and  FIG. 2  in order to describe the present invention in detail. The present invention provides a mouse device with ultraviolet for disinfection  20 , which comprises a mouse device  22  having a basic mouse structure seen in the market generally. A housing of the mouse device  22  is the plastic housing having all kinds of color or drawings. A light directing layer  23  is disposed on an outer surface of the mouse device  22 . The thickness of the light directing layer  23  is from 0.1 cm to 0.8 cm approximately and the material of the light directing layer  23  is selected from acrylic or unleaded glass. Besides, the light directing layer  23  has at least one groove  231 , which surrounds the waist of said light directing layer  23 , and which is inserted with at least one lighting object. 
     The present invention is exemplified by a plurality of lighting objects. The lighting object of the embodiment is LED light bulb  28 , which are arranged the waist of the light directing layer  23  along the grooves  231 . The LED light bulb  28  can emit ultraviolet  30  outwardly by utilizing a power source applied by the mouse device  22 , wherein ultraviolet is directed by the light directing layer  23  to spread on the outer surface of the mouse device  22 . In the embodiment, the LED light bulb  28  is covered with a light-shield layer  25  disposed above the grooves  231 , whereby ultraviolet emitted from the LED light bulb  28  is directed to spread toward the light directing layer  23  more easily. In other words, ultraviolet is spread on the outer surface of the housing  221  of the device mouse  22  uniformly, so as to achieve the ultraviolet disinfection effect with safety, environmental protection, none environmental pollution, and human body-nonjuring properties. Therefore, the number of the bacterium propagated on the outer surface of the mouse device  22  will be decreased, and the users will be protected from irritation reaction. 
     The grooves  231  are inserted with the light-shield layer  25 , whose top and the top of the groove  231  are located at the same level. Thus, the light-shield layer  25  is formed a unity with the light directing layer  23 , and towering feeling is not induced for appearance and using feel. 
     In addition, a switch  32 , disposed on the outer surface of the mouse device  22 , is coupled the LED light bulb  28 . When the switch  32  is turned on and a user is using the mouse device  22 , the LED light bulb  28  stops to emit ultraviolet outwardly, and the LED light bulb  28  does not emit ultraviolet outwardly to disinfect until the user does not use the mouse device  22 . When the switch  32  is turned off, the LED light bulb  28  does not emit ultraviolet. The second embodiment of the present invention is shown in  FIG. 3 . The difference of the second embodiment and the preceding embodiment in that a photocatalyst layer  26  is disposed on the outer surface of the light directing layer  23 . Photocatalyst is a catalyst, which is catalyzed by utilizing optical energy. Firstly, photocatalyst is coated or sprayed to form a thin film on the outer surface of the light directing layer  23 . When the LED light bulb  28  emits ultraviolet  30  to disinfect, optical energy of the ultraviolet  30  activates the photocatalyst layer  26  to react oxidization or reduction with the bacterium attached to the outer surface of the mouse device  22 , so as to achieve the purpose of disinfection and bacteriostasis. 
     The third embodiment of the present invention is shown in  FIG. 4 . The difference of the third embodiment and the second embodiment in that the third embodiment has a plurality of fluorescent tubes  36  used as the lighting object. 
     The fourth embodiment of the present invention is shown in  FIG. 5  and  FIG. 6 . A prism member  24  is disposed on the inner surface of the light directing layer  23 . When the ultraviolet  30  passes through the prism member  26 , the ultraviolet  30  is refracted by the prism member  26 , so as to help the ultraviolet  30  emitted from the LED light bulb  28  spread on the outer surface of the mouse device  22  uniformly. 
     The fifth embodiment of the present invention is shown in  FIG. 7 . The difference of the fifth embodiment and the fourth embodiment in that the fifth embodiment has a plurality of fluorescent tubes  36  used as the lighting object. 
     The embodiments described above are only to exemplify the present invention but not to limit the scope of the present invention. Therefore, any equivalent modification or variation according to the shape, structures, characteristics and spirit disclosed in the present invention is to be also included within the scope of the present invention.
