Claim:
1. A waste compression device with a fee calculation function, comprising a casing, the casing having a waste inlet disposed on an outer wall of the casing, and having therein: a control unit; a compression unit positioned proximate to a top of the casing and electrically connected to the control unit; a storage cart disposed beneath and corresponding in position to the compression unit, the storage cart being in communication with the inlet, such that wastes fall into the storage cart; a vibration unit disposed at a bottom of the storage cart, electrically connected to the control unit, and shakes the storage cart, such that the wastes in the storage cart level off; a quantity sensor, disposed in the inlet and electrically connected to the control unit, comprising an emitting element and a receiving element receiving a signal emitted from the receiving element where the emitting element and the receiving element correspond in position to each other, and the quantity sensor being capable of calculating a quantity of the wastes in such a way that when the signal is blocked by one of the wastes passing through the waste inlet between the emitting element and the receiving element, the quantity sensor senses the one of the wastes, thereby calculating the quantity of the wastes and sending a quantity signal to the control unit; a storage level sensor, disposed at a proximal side of the storage cart and electrically connected to the control unit, and comprising an emitting component, a receiving component receiving a signal emitted from the emitting component where the emitting component and the receiving component correspond in position to each other, and a counter for counting a number of times a level of the wastes reaching a preset height, the storage level sensor capable of determining whether the level of the wastes in the storage cart reaches the preset height, such that once the wastes in the storage cart accumulate enough to rise above at the preset height and block the signal from the emitting component, the storage level sensor sends a level signal to the control unit, and wherein an interface unit exposed from the casing, electrically connected to the control unit, receiving the quantity signal and display the quantity of the wastes, and sending an acknowledgment signal to the control unit, so as to cause the control unit to generate a ticketing signal; and a ticketing unit exposed from the casing, electrically connected to the control unit, and receiving the ticketing signal and dispense a coupon.
