s4: an internal rotating wheel of the clockwork timer (11) continuously rotates in the cracking process to drive an internal gear (14) to synchronously rotate, the internal gear (14) transmits the rotating force to a rotating arm (17) through a connecting shaft (15) to drive the rotating arm (17) to synchronously rotate until the front edge of the rotating arm (17) slides into a potential rotating groove (18) and triggers a power switch (19), the timing of the clockwork timer (11) is finished, the cracking process is stopped, and the water cooling mechanism (3) is started;
s5: the electric water pump (31) pumps the water filled in the cracking box (21) through the water inlet pipeline (32), and the water is purified by the water purifier (34) and then is injected into the cracking box (21) again through the water outlet pipeline (33).
