Abstract
An improved mailbox designed to rid bacteria and other biological germs present in contents. Designed as a mailbox for small-business or home, the mailbox has a housing assembly with an access door. Within the housing is an ultra violet and ozone generating system. At a rear section of the housing assembly is an extractor assembly, which includes an air intake, filtering system, and extraction fan. When the access door is opened, a micro-switch is triggered, activating a timer assembly. For a first predetermined amount of time, the ultra violet and ozone generating system operate to sterilize bacteria and other biological germs present in the contents, while an “unsafe” indicator is illuminated. Once that operation is complete, the extractor assembly operates for a second predetermined time. When the second predetermined time expires, a “safe” indicator illuminates, notifying a user that the contents have been sterilized for a predetermined amount of time.
Description




II. BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a mailbox, and more particularly, to an improved mailbox that rids bacteria and other biological germs present in contents.




2. Description of the Related Art




Many designs for mailboxes have been designed in the past. None of them, however, include a system designed to rid contents of bacteria and biological germs, such as anthrax.




Prior art teaches that Ultra Violet “UV” irradiation and ozone can effectively sterilize bacteria and biological germs.




Designed as a personal mailbox for small-business or home, the instant invention has a housing assembly with an access door. Within the housing is an ozone generating system. At a rear section of the housing assembly is an extractor assembly, which includes an air intake, filtering system, and extraction fan.




When the access door is opened to place contents, a micro-switch is triggered, activating a timer assembly. For a first predetermined amount of time, the ozone generating system operates to sterilize bacteria and other biological germs present in the contents. An “unsafe” indicator illuminates during the operation of the ozone generating system. At the completion of the operation of the ozone generating system, the extractor assembly is activated for a second predetermined time. Once the extraction operation is complete, a “safe” indicator illuminates, notifying a user that the bacteria and biological germs have been sterilized and rid of.




The instant invention protects the user from viruses and bacteria that are be present in contents that are mailed.




There are no mailboxes to the best of applicant's knowledge, which include a housing assembly having an access door, wherein the housing assembly has an ozone generating system and an extractor assembly, and where electronic means notify a user when bacteria and biological germs have been sterilized for a predetermined amount of time from contents mailed.




III. SUMMARY OF THE INVENTION




A mailbox for contents, comprising a housing assembly having an access door, where the housing assembly is substantially hollow. An indicator assembly having electronic means, notifies a user when the contents are free of bacteria and biological germs while in the housing assembly. Ultra violet and ozone generating means radiate the contents within the housing assembly with rays and ozone, to effectively sterilize the bacteria and biological germs existing within the housing assembly. Circulation means circulate sterilized bacteria and biological germs out of the housing assembly.




More specifically, the housing assembly has an access door and first, second, and third walls. The access door and the first wall are in a parallel and spaced-apart relationship with respect to the second and third walls and the second wall has a through-hole. A mounting post may elevate the housing assembly.




The circulation means to circulate sterilized bacteria and biological germs out of the housing assembly comprises an extractor assembly having an air intake, filtering system and extraction fan. The air intake has cooperative dimensions to mount within the housing assembly and specifically onto the through-hole. The filtering system retains the sterilized bacteria and biological germs when the extraction fan is operating.




The electronic means comprises at least one visual indicator that illuminates to notify the user when the bacteria and biological germs have been sterilized for a predetermined time and rid of from the contents.




The bacteria and biological germs as an example can be anthrax.




It is therefore one of the main objects of the present invention to provide a mailbox that rids bacteria and biological germs that may be present in contents.




It is another object of this invention to provide a mailbox that permits a user to safely process contents.




It is another object of the present invention to provide a mailbox with a source of ozone by means of an ultra violet lamp, or other ozone generator, for sterilizing or decontaminating contents.




It is still another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.




Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

44


illuminates, notifying the user that it is “unsafe” to open door


24


.




When the first predetermined amount of time expires for timer


52


, extractor assembly


70


operates for a second predetermined time with timer


53


. Specifically, fan


86


operates to circulate the sterilized bacteria and other biological germs out of housing assembly


20


. Air from within housing


20


circulates through holes


78


and


74


, through filter


84


, and circulates out of instant invention


10

90


notifies the user when ozone-producing assembly


60


is not functioning. Specifically, when ozone-producing assembly


60


malfunctions, photocell diode


92


and relay


94


are activated to set off alarm


96


. Alarm


96


in turn sends a signal to speaker


98


, which sounds off to notify the user of the malfunction.
