Abstract:
The present invention provides an ultraviolet light toothbrush sanitizing-box for bacteria prevention and toothbrush dehumidification. The ultraviolet light toothbrush sanitizing-box will sterilize the toothbrush with ultraviolet light and dehumidify the toothbrush storage environment, thereby maintaining the toothbrush in a germ-free condition before each use and prolonging the life-span of the toothbrush.

Description:
FIELD OF THE INVENTION  
       [0001]    The present invention relates to a toothbrush container; more particularly, the present invention relates to a toothbrush container with automatic ultraviolet light sanitizing system. 
       BACKGROUND OF THE INVENTION 
       [0002]    Most people often brush their teeth in a rush, and the germs are left on the toothbrush in a wet condition after the use, leaving an ideal condition for germ-development, therefore, many report suggest that the toothbrush should be replaced every month or so; however, even replacing the toothbrush regularly can not guarantee that the toothbrush is always in the germ-free condition, as the germ development is fast in the bathroom if the food remains are carelessly stained on the toothbrush after the use. 
         [0003]    Therefore, the main objective of the present invention is to provide a feasible solution to enhance the oral hygiene for everyone. 
       SUMMARY OF THE INVENTION 
       [0004]    1. It is the primary objective of the present invention to provide an ultraviolet toothbrush sanitizing-box capable of germ prevention and dehumidification to maintain the toothbrush in a germ-free condition before each use. 
         [0005]    2. It is the second objective of the present invention to provide a safe and efficient control method of the toothbrush sanitizing-box, thereby preventing the user from directly facing the ultraviolet light during the toothbrush sanitizing process. 
         [0006]    3. It is the third objective of the present invention to provide an ultraviolet toothbrush sanitizing-box for prolonging the life-span of the toothbrush. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0007]      FIG. 1  is the illustrative view of the ultraviolet toothbrush sanitizing-box. 
           [0008]      FIG. 2  is another construction of the ultraviolet toothbrush sanitizing-box with a cylindrical shape. 
       
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0009]    The present invention is shown in  FIG.1 , the components are labeled as follows, the toothbrush holder  123 , the power-supply  100 , the ultraviolet light tube  110 , the lid member  122 , the lid sensor  132 , the sanitizing-box  121 , the control circuit  130 , the sanitizing process indication light  140 . 
         [0010]    The sanitizing-box  121  is preferable to be a a completely concealed space when the lid member  122  is shut, thereby keeping the water vapor out of the sanitizing-box  121  during the sanitizing process. 
         [0011]    The lid member  122  will block the ultraviolet light from the ultraviolet light tube  110  during the sanitizing process; and at any given conditions, the control circuit  130  (or the lid sensor  132 ) will directly disable the power to the ultraviolet light tube  110  if the lid member  122  is detected to be in the open condition, thereby preventing the user from direct exposure to the ultraviolet light. 
         [0012]    The sanitizing process indication light  140  will be turned on during the sanitizing process to signify the user that the sanitizing process is still ongoing. 
         [0013]    There are two basic control methods for the present invention: 
         [0014]    The first control method is defined as follows, when the control circuit  130  detects an opening action and a closing action of the lid member  122 , the control circuit  130  will commence the sanitizing process by turning on the ultraviolet light tube  110  for a pre-set time period, the ultraviolet light will dehumidify and sterilize the toothbrush during this process. 
         [0015]    The second control method is defined as follows, with the addition of a schedule-timer to the control circuit, the user can schedule one or more sanitizing processes at the certain time of the day with said schedule-timer, therefore, the user can make sure the toothbrush is in a germ-free condition prior to each use; this second method is more preferable in many common scenarios, for example, the user brush his teeth once at 11 pm and once at 6 am, even though the first control method can dehumidify and sterilize immediately after the use at 11 pm, there is still a time period of 7 hours for the germs to grow if the food remains are carelessly stained on the toothbrush during the storage, therefore, by setting the schedule timer to commence the sanitizing process at about 5:30 am and 10:30 pm in this scenario, the germ development on the toothbrush will be kept at a minimum level even if the toothbrush is not properly stored in a clean condition. 
         [0016]    The best mode of the present invention is to embed both the first control method and the second control method in the control circuit, however, each method should be able to stand-alone for different user preference. 
         [0017]    The power-supply of the ultraviolet toothbrush sanitizing-box can be a battery or a rechargeable battery. 
         [0018]    The power-supply of the ultraviolet toothbrush sanitizing-box can be a power-supply directly connected to the wall plug. 
         [0019]    The lid member and the sanitizing-box can further comprise mirror to reflect the ultraviolet light and increase the intensity of the ultraviolet light during the sanitizing process. 
         [0020]    The sanitizing-box can further comprise a temperature sensor to detect the temperature change in the concealed space of the toothbrush during sanitizing process, if the temperature sensor detects an overheat condition, the control circuit will stop the sanitizing process. 
         [0021]    The sanitizing-box can be a cylindrical box as shown in  FIG. 2 , wherein all the basic components are similar to the component in  FIG. 1  with a shape orientation to fit in a cylindrical sanitizing-box; the components are labeled as follows, the toothbrush holder  223 , the power-supply  220 , the ultraviolet light tube  210 , the lid member  222 , the lid sensor  232 , the sanitizing-box  221 , the control circuit (embedded with the power supply  220 ), the sanitizing process indication light  240 .
