Furthermore, the outer surface and the mark 231 of the sliding sheet 23 have different colors. Preferably, the color of the outer surface of the sliding sheet 23 is same or different from the colors of the two covering plates 22. The amount of the sliding sheets 23 of one of the operating sets 20 is fewer than amount of the other operating sets 20 to form a gap on the operating set 20, and this can enable the sliding sheets 23 of the operating set 20 to move to another operating set 20 via the gap.
In use, with reference to FIG. 5, a user can turn the educational ball over to enable the operating set 20 that has fewer sliding sheets 23 to move to a top of the educational ball. In the first embodiment of an educational ball, the gap is formed in the sliding groove 25 of the corresponding operating set 20. With reference to FIG. 6, the user can rotate one of the adjacent operating sets 20 to enable one of the sliding sheets 23 of the adjacent operating set 20 to align with the gap. Then, the user can push the corresponding sliding sheet 23 to move into the gap to fill the sliding groove 25 of the operating set 20 that has fewer sliding sheets 23 as shown in FIG. 7, and the gap is moved and formed on the adjacent operating set 20.
According to the above-mentioned operation, the user also can rotate two adjacent operating sets 20 to enable the gap to align with one of the track grooves 224 of one of the two adjacent operating sets 20 to form different spatial arrangements. In addition, each one of the operating sets 20 can be rotated relative to the four adjacent operating sets 20 to move the sliding sheets 23 between the operating sets 20. Furthermore, the user can move the sliding sheets 23 in the track grooves 224 annularly according to the order and sequence of numerals or English alphabets or move the sliding sheets 23 in the sliding grooves 25 to align with each other according to the order and sequence of numerals or English alphabets. In addition, the user also can push the sliding sheets 23 with same colors to move in the track grooves 224 and the sliding groove 25 of one of the operating sets 20. Therefore, the educational ball in accordance with the present disclosure can provide different spatial arrangements and modes of operation, and this can increase operational variability, fun and challenge of using the educational ball. Then, the training effect of mental, spatial concepts and logical thinking for the users can be improved by the educational ball of the present disclosure.
With reference to FIG. 8, a second embodiment of an educational ball in accordance with the present disclosure is substantially the same as the first embodiment except for the following features. Only one of the operating sets 20 has a sliding groove 25, and the mark 231 of each one of the sliding sheets 23 is an English alphabet.
With reference to FIG. 9, a third embodiment of an educational ball in accordance with the present disclosure is substantially the same as the first embodiment except for the following features. Each rotating mount 21A of the operating sets 20A does not have the engaging ring 212 and the cutting slots 213, and the engaging jacket 211 cannot be deformed.
