[0032] For the ice cream machine, the puffing pump motor, the connecting shaft 7 and the pump seat 6 are fixed parts and are generally not disassembled. During use, only the puffing pump body needs to be disassembled and cleaned. The installation, disassembly and cleaning process of the puffing pump is as follows: during installation, the triangular shaft head 502 at the lower end of the main shaft 5 of the spherical puffing pump is first inserted into the triangular shaft hole 701 at the outer end of the connecting shaft 7, and the U-shaped pin hole 302 at the lower end of the cylinder body 3 is aligned and clamped on the cylindrical pin 9 on the pump seat 6, and then the clamping plate 4 is clamped into the clamping groove 301 on the outer circumference of the cylinder body 3, so that the puffing pump is fixed on the pump seat 6; when the puffing pump needs to be disassembled and cleaned after use, the clamping plate 4 is first radially pulled out from the cylinder body 3, and then the spherical pump is pulled out as a whole along the axial direction, and then the knurled screw 11 on the cylinder cover 2 is quickly removed, and the main shaft 5 and the rotor 1 are taken out after the cylinder cover 2 is opened, and each part is rinsed.

[0033] The spherical pump comprises a cylinder body 3, a cylinder head 2, a piston 101, a rotating disk 102 and a main shaft 5. The piston 101 and the rotating disk 102 are hinged to form a rotor 1.

The cylinder body 3 and the cylinder head 2 are connected by a knurled screw 11, and a cross hole is arranged on the circumference of the head of the knurled screw 11, and a slot is arranged on the top surface of the head end of the knurled screw 11, and a knurled pattern is arranged on the circumference of the head; during installation and disassembly, the knurled screw 11 can be tightened and loosened by inserting a rod-shaped tool into the cross hole, or by inserting a flat-blade screwdriver into the slot to tighten or loosen the knurled screw 11, and the tool selection is convenient.

[0034] like Figure 10 to Figure 12As shown, the piston 101 has a spherical top surface and two side surfaces, a piston shaft 1011 is arranged in the center of the spherical top surface, and a piston pin seat 1012 is arranged at the lower ends of the two side surfaces of the piston 101; the turntable 102 has a turntable spherical surface, a turntable shaft is arranged in the lower center of the turntable spherical surface, a sliding shoe 1021 is arranged at the lower end of the turntable shaft, and a turntable pin seat 1022 is arranged at the upper end of the turntable spherical surface; the piston pin seat 1012 is a semi-cylinder protruding from the lower end of the piston 101, the cylindrical center axis of the semi-cylinder is perpendicular to the axis of the piston shaft 1011 and passes through the center of the spherical surface of the piston, and the two ends of the semi-cylinder are the spherical surfaces of the piston; the turntable pin seat 1022 is a semi-cylindrical hole opening upward, and the center axis of the semi-cylindrical hole is perpendicular to the axis of the piston shaft 1011 and passes through the center of the spherical surface of the piston. The axis of the turntable shaft is vertical, the semi-cylindrical hole matches the semi-cylinder, and the semi-cylinder of the piston pin seat 1012 is inserted into the semi-cylindrical hole of the turntable pin seat 1022 to form a C-shaped cylindrical hinge; the sliding shoe 1021 at the end of the turntable shaft is inserted into the slide groove 503 at the upper end of the main shaft 5 to form a slide groove swing mechanism, and the two side surfaces of the sliding shoe 1021 and the two side surfaces of the slide groove 503 fit together to form a sliding fit, and a triangular shaft head 502 is provided at the lower end of the main shaft 5, and the triangular shaft head 502 matches the triangular shaft hole 701 at the outer end of the connecting shaft 7. The triangular shaft head 502 is inserted into the triangular shaft hole 701 so that the connecting shaft 7 rotates to drive the main shaft 5 to rotate, thereby forming a rotational fit; the axis of the main shaft 5 forms a certain angle with the axis of the piston shaft 1011 and both are passed through the ball The piston shaft 1011 is inserted into the piston shaft hole 205, and the piston 101 and the turntable 102 are hinged by a cylindrical hinge to form a rotor 1. The piston spherical surface, the turntable spherical surface and the inner surface of the spherical cavity have the same spherical center and form a sealed dynamic fit. A sealed dynamic fit is formed between the matching surfaces of the cylindrical hinge. The motor drives the turntable 102 to rotate through the connecting shaft 7, and the piston 101 and the turntable 102 swing relative to each other around the cylindrical hinge. A V1 studio and a V2 studio with alternating volumes are formed between the upper end surface of the turntable 102, the two side surfaces of the piston 101 and the spherical cavity; during the rotation of the rotor, the volumes of the V1 studio and the V2 studio change alternately, and are alternately connected with the liquid inlet groove 203 and the liquid discharge groove 204. Groove 204 is connected: when the volume of the V1 studio begins to increase, the liquid inlet groove 203 is connected to the V1 studio to absorb liquid. When the volume of the V1 studio reaches or approaches the maximum state, the liquid inlet groove 203 is disconnected from the V1 studio and the liquid inlet stops. After the V1 studio completes the liquid absorption, it starts to compress and the volume begins to decrease again. At this time, the volume of the V2 studio begins to decrease and the liquid pressure increases. When the pressure increases to the set pressure, the liquid discharge groove 204 is connected to the V2 studio to start discharging high-pressure liquid. When the volume of the V2 studio reaches or approaches the minimum state, the liquid discharge groove 204 is disconnected from the V2 studio to stop discharging liquid. After the high-pressure liquid is discharged, the volume of the V2 studio starts to increase again. This cycle is repeated to complete the liquid compression work.

[0035] In order to prevent milk slurry leakage, a sealing ring is provided between the middle journal of the motor connecting shaft 7 and the shaft sleeve 8, and a sealing ring is provided between the outer end journal of the motor connecting shaft 7 and the inner shaft hole at the end of the pump seat 6. An "O" sealing ring is provided between the connecting surfaces of the cylinder body 3 and the cylinder head 2.

[0036] During the rotation of the spherical expanding pump rotor, a gas-liquid mixture appears in the gap around the liquid inlet groove 203 as compressed gas. Therefore, in the gap between the liquid inlet hole 201 sucking liquid and sucking air, when the compressed gas near the liquid inlet groove 203 passes through the gap and is sprayed back from the suction pipe 12 along with the liquid, the sprayed gas-liquid mixture enters the lower straight hole 131 from the channel of the liquid inlet hole 201. When it is sprayed upward in the lower straight hole 131 to the bottom of the lower straight hole, the liquid is blocked from flowing back, and the gas therein is separated and enters the upper straight hole 132 through the connecting hole 133, and then is discharged from the intake pipe 12 from the upper straight hole 132, thereby eliminating the problem of liquid directly spraying back from the intake pipe 12.
