A leakproof arrangement of a chocolate fountain includes a leakproof device tightly fastened within the through hole of the basin. The leakproof device has i) a base sealed to the periphery of the through hole of the basin; ii) a plurality of support frames disposed around the base; and iii) a shaft sleeve disposed at the center of the base, the joint between the shaft sleeve and the base being tightly sealed without any gaps, the height h2 of the shaft sleeve being greater than the maximal chocolate level h1, the connection end at the top of the shaft sleeve rising above the height h2 of the shaft sleeve. In this way, the melted chocolate will never flow over the shaft sleeve such that downward leakage may be avoided. As a result, the leakage of the melted chocolate is prevented, thereby ensuring a smooth operation of the transmission element as well as a prolonged service life.
