This money box we design ensure that coins can freely slip down through a side with an angle in the vertical direction, while in the horizontal direction, there is also an angle, together with a baffle on the lateral, thus ensuring the coin to slip in the accurate direction. According to different sizes of coins, from top to bottom, we design three holes corresponding to the size of 0.1RMB, 0.5RMB and one Yuan, so that the coins can effectively be classified when slipping down.We also design three coin returns corresponding to different areas at the bottom of the box, we can accurately take out the coins of certain denomination as we require.
