Broken bubble machine of seat headrest

The utility model discloses a broken bubble machine of seat headrest, including lower mould and last mould, it is connected with actuating mechanism to go up the mould, actuating mechanism can drive it is relative to go up the mould lower mould reciprocating motion. Above -mentioned broken bubble machine of seat headrest's concrete working process is placed between upper and lower mould for the headrest that will treat brokenly the bubble, and relative lower mould reciprocating motion goes on once or multiple squeezing the headrest through mould in the actuating mechanism drive for the cell volume of sponge in the headrest diminishes, gas intensity of pressure increase in the abscess, and when being greater than atmospheric pressure and abscess wall effort, gaseous broken bubble is escaped, realizes the broken bubble exhaust of sponge. It needs the evacuation to come brokenly the mode of steeping to compare in traditional broken bubble machine, has reduced the energy consumption greatly, avoids the time of ev
