The structure between two adjacent juice collecting holes can increase the rigidity of the side wall of the box body, and the reinforcement layer and the juice collecting layer are integrally formed, which can improve the stability of the squeezing device.

[0010] Preferably, the spacing of the small head end opening structure is smaller than the aperture of the filter layer. The structure in this technical solution can further filter the papaya pulp and prevent it from entering the juice collection hole.

[0011] Preferably, the box body further comprises a clamp tied to the outer periphery of the box body, which can prevent the box body from being damaged under the heavy pressure of the cylinder.

[0012] Preferably, it also includes a pivot shaft fixedly connected to the support and an axial hole matched with the pivot shaft, wherein the axial hole is fixedly arranged on the outer wall of the box body. The pivot structure can rotate the box body away from the bottom of the pressure cover, so as to facilitate cleaning of the remaining pulp inside the box body.

[0013] Preferably, the juice collecting layer further comprises an ultrasonic filter disposed at the bottom of the juice collecting hole, wherein the filter hole size of the ultrasonic filter is smaller than the filter hole size of the filter layer. The ultrasonic filter can further filter the pulp entering the juice collecting hole, and at the same time, prevent the pulp from clogging the filter under the vibration of the ultrasonic wave, thereby avoiding affecting the juice collection efficiency.
