Abstract:
An improved garbage container with automatic opening and closing functions, comprising a garbage container and a garbage can that is disposed in a central space of said garbage container, that can be pulled out of or pushed into said garbage container, and that can receive a garbage bag fitted thereon, whereinsaid garbage container has a projecting portion on one side, said projecting portion accommodating therein an electric control system, a top side of said garbage container being provided with a feed slot, an inner side of a bottom edge of said feed slot being provided with two cover plates, one side of said cover plates being connected to a linking-up device;two parallel rails are provided below said feed slot for slidable displacement of said two cover plates, two side ends of opening travel of said slide rails being respectively provided with a stop block, a cigarette extinguishing groove being provided on a top edge of said projecting portion, said cigarette extinguishing groove having an opening partitioned by a plurality of partition plates;said electric control system including a control panel that is comprised of an electronic integrated circuit board, said control panel having an electronic eye for detecting approaching objects and a plurality of manually controlled control keys provided thereon, a sensing end extending to above said garbage can for detecting the level of garbage accumulated therein, and a control wire connected to said linking-up device for driving said cover plates;said cover plates are juxtaposed and disposed in a relative space of said slide rails so that they can relatively slidably displace, said cover plates being provided with toothed ends on side ends that correspond to said electric control system for abutting against a transmission device, the outer sides of the toothed ends being respectively provided with a positioning end, said positioning ends displacing outwardly to a bottom end of the travel to abut against said stop blocks for positioning purposes, and abutting against a transmission portion of said transmission device during return travel, said transmission device including two drive motors secured by securing seats below inner edges of the top side of said container body, a transmission end thereof being provided with a transmission gear that engages said toothed ends of said cover plates for transmission purposes and that is connected to said control panel via control wires;whereby when said electronic eye detects an approaching user, it sends a signal to said control panel which drives said transmission device to cause said cover plates to open or close said feed slot, so that the user needs not touch said garbage container when dumping garbage, and when said sensing end detects that the level of garbage inside said garbage can has reached a determined level, it sends a signal to said control panel to emit an alert sound, and said control panel hence prohibits opening of said cover plates to avoid over-dumping of garbage, said control keys being provided to allow manual operation of said cover plates when necessary.
