wherein an outer edge of the supporting ring is downwards folded to form a ring slot, a lower surface of the upper folding part is provided with a stopper; and the stopper is a stop block which is [ detachably ] clamped in the ring slot [ ;
wherein the stopper is detachable in a manner that in an unfolded state of the folding bathtub, the stop block is clamped in the ring slot at a first position where two ends of the stopper respectively extend to the first ring part and the second ring part to limit downward rotation of the first ring part and the second ring part, and in a folded state of the folding bathtub, the stopper is detached from the first position] .
[ 15. The folding bathtub according to claim 1, wherein in the folded state of the folding bathtub, the stopper is changed to a second position at an edge of a single side of the supporting ring to facilitate a storage of the stopper.]
[ 16. The folding bathtub according to claim 15, wherein the supporting ring and the tub body are detachably connected.]
[ 17. The folding bathtub according to claim 10, wherein in the folded state of the folding bathtub, the stopper is changed to a second position at an edge of a single side of the supporting ring to facilitate a storage of the stopper.]
[ 18. The folding bathtub according to claim 17, wherein the supporting ring and the tub body are detachably connected.]
