A smart bulk toothpaste vending machine comprising an enclosure (1), a toothpaste injecting apparatus (2), a toothpaste tube cleaning apparatus (3), a currency identifier (4), and a controller (5). The toothpaste injecting apparatus (2) comprises bottled toothpaste (6), a first solenoid valve (7), an electric push rod (8), and a bulk toothpaste tube (9). The bulk toothpaste (6) comprises a sealed bottle (10), an injecting piston (11), and toothpaste (12). The bulk toothpaste tube (9) comprises a guide cylinder (15), a toothpaste cylinder (16), a piston (17), and a piston rod (18). The first solenoid valve (7) is connected to the bottled toothpaste (6) and to the bulk toothpaste tube (9). The toothpaste tube cleaning apparatus (3) comprises a clean water reservoir (21), a water-injecting pump (22), a water-drawing pump (23), a second solenoid valve (24), a third solenoid valve (26), and a waste water reservoir (25). The currency identifier (4) comprises a control board (33), a coin inlet (34), a banknote inlet (35), and a refund outlet (36). When the toothpaste (12) in the bulk toothpaste tube (9) is depleted, the toothpaste tube cleaning apparatus (3) is utilized to clean the bulk toothpaste tube (9), and new toothpaste (12) is injected into the bulk toothpaste tube (9), thus allowing reuse of the bulk toothpaste tube (9), and facilitating energy conservation, emission reduction, and environmental protection. |
