4. A compressed waste bin as claimed in claim 3, wherein: a guide rib is arranged on the side wall of the garbage input cavity, and a guide notch matched with the guide rib is arranged at the edge of the lower push plate; when the lower push plate is arranged in the garbage throwing cavity, the guide notch at the edge of the lower push plate is matched with the guide edge on the side wall of the garbage throwing cavity.
5. The garbage compression method is applied to the compressed garbage can disclosed in claim 4, and is characterized in that the compressed garbage can is in an initial state before being used, and at the moment, garbage is not put into the cavity or does not exceed a preset height; the lower push plate is positioned at the lowest end of the movement stroke; the inner movable plate closes the communication port A; the upper top plate opens the garbage inlet; the side pushing plate is in a retracted state;
the method comprises the following steps:
s01, automatically starting garbage compression: the garbage is put into the garbage input cavity from the garbage input port, when the garbage in the garbage input cavity exceeds the preset height defined by the ultrahigh detection sensor, the upper top plate control mechanism controls the upper top plate to close the garbage input port, then the lower push plate driving mechanism controls the lower push plate to move upwards, the garbage in the garbage input cavity is compressed, and when the lower push plate moves to the highest position or the pressure detected by the pressure sensor A in the upper top plate reaches a preset value, the garbage compression is completed;
s02, pushing the compressed garbage out of the garbage input cavity and entering the garbage cavity to be taken: the inner movable plate control mechanism controls the inner movable plate to open the communication port A, then the side pushing plate driving mechanism controls the side pushing plate to extend out, compressed garbage in the garbage input cavity is pushed into the garbage cavity to be taken from the communication port A, after the pressure sensor B at the bottom of the garbage cavity to be taken detects that garbage falls into the garbage cavity, a signal is transmitted to the singlechip, and the singlechip controls the status indicator lamp to be normally on so as to remind people to take out the garbage;
s03, automatically starting garbage compression again: all parts in the compressed garbage can are restored to an initial state, garbage can be put into the garbage input cavity from the garbage input port at the moment, and when the garbage exceeds a preset height, garbage compression is started again automatically;
in the step, the garbage compression process is consistent with the garbage compression process in the step S01;
s04, identifying the state of the compressed dustbin through an indicator lamp: after compression is finished, if the pressure sensor B detects that the garbage in the garbage cavity to be taken is not taken out, the single chip microcomputer controls the state indicator lamp to flash so as to remind people to take out the garbage, and all parts in the garbage can are compressed until the garbage in the garbage cavity to be taken out, so that the current situation is maintained, and no action is performed; if the pressure sensor B detects that the compressed garbage in the garbage cavity to be taken out is taken out, the inner movable plate control mechanism controls the inner movable plate to open the communication port A, then the side pushing plate driving mechanism controls the side pushing plate to extend out, the compressed garbage in the garbage cavity to be taken out is pushed into the garbage cavity to be taken out from the communication port A, and the status indicator lamp becomes normally on so as to remind people to take out the garbage again;
in the step, when the pressure sensor B does not detect that the garbage is stored in the garbage to-be-taken cavity and the garbage in the garbage input cavity does not exceed the preset height defined by the ultrahigh detection sensor, the status indicator lamp is kept off.
