[0023] Reference Figure 3 、 Figure 4 、 Figure 5 The specific structure of the eccentric pump 4 is as follows: the eccentric pump 4 includes a pump body 401, and an eccentric groove 402 is eccentrically provided on the upper surface of the pump body 401. The eccentric groove 402 is a circular structure, and is formed by the upper surface of the pump body 401 being recessed downward. A rotating head 403 is provided in the eccentric groove 402, and the top surface of the rotating head 403 is flush with the upper surface of the pump body 401. A mounting groove is provided on the rotating head 403, and the mounting groove extends downward from the top of the rotating head 403 to the bottom of the rotating head 403. A first extrusion block 404 and a second extrusion block 405 are installed in the mounting groove, and the top surfaces of the first extrusion block 404 and the second extrusion block 405 are flush with the top surface of the rotating head 403. Two mounting holes 7 arranged vertically are provided on the side of the first extrusion block 404 close to the second extrusion block 405, and two mounting holes 7 arranged vertically are provided on the side of the second extrusion block 405 close to the first extrusion block 404. The mounting holes 7 on the first extrusion block 404 and the second extrusion block 405 correspond one to one, and springs 8 are installed in the corresponding two mounting holes 7. The springs 8 press the first extrusion block 404 and the second extrusion block 405 against the inner walls of the eccentric groove 402 respectively.

[0024] A rotating shaft 406 is disposed within the pump body 401. The upper end of the rotating shaft 406 is connected to the rotating head 403, and the lower end of the rotating shaft 406 extends out of the pump body 401. The lower end of the rotating shaft 406 is connected to a connector 407. The rotating shaft 406 is inserted into the connector 407 and fixedly connected by a locking rod 408. Corresponding connecting holes 6 are respectively formed in the rotating shaft 406 and the connector 407, and the locking rod 408 is fixedly inserted into the connecting hole 6.

[0025] Reference Figure 2 、 Figure 6A connecting shaft 5 is provided in the connecting seat 3. A socket 501 is provided at the top of the connecting shaft 5. The connector 407 at the bottom of the eccentric pump 4 is inserted into the socket 501. The bottom end of the connecting shaft 5 is connected to the output shaft of the motor 1. The motor 1 can drive the connecting shaft 5 to rotate. The connecting shaft 5 drives the connector 407 at the bottom of the eccentric pump 4 to rotate, thereby driving the rotating shaft 406 and the rotating head 403 to rotate.

[0026] Reference Figure 2 , Figure 7 When the vertical eccentric pump mechanism of this embodiment is specifically installed, the connecting seat 3 is fixedly connected to the motor mounting seat 2 through multiple first locking rods 9, and the eccentric pump 4 is fixedly connected to the connecting seat 3 through multiple second locking rods 10.

[0027] Reference Figure 1 When the vertical eccentric pump mechanism of this embodiment is used, it is also necessary to install the reversing mechanism a on the eccentric pump 4. The second locking rod 10 passes through the reversing mechanism a, the eccentric pump 4 and the connecting seat 3 in sequence to fix the reversing mechanism a, the eccentric pump 4 and the connecting seat 3 together. Figure 8 The specific structure of the reversing mechanism a is that a first through hole a1 and a second through hole a2 are provided at the bottom of the reversing mechanism a, and the first through hole a1 and the second through hole a2 are used for the entry and exit of materials.

[0028] When the vertical eccentric pump mechanism of this embodiment is working, the motor 1 drives the eccentric pump 4 to rotate, so that negative pressure is generated in the pump body of the eccentric pump, and the cream mixed with the air is sucked into the eccentric pump 4 through the first through hole a1 at the bottom of the reversing mechanism a. Under the high-speed rotation of the rotating head 403, the first extrusion block 404 and the second extrusion block 405 are driven to rotate at high speed. The first extrusion block 404 and the second extrusion block 405 are restricted by the eccentric groove 402 and are extended and retracted under the action of the spring 8. The first extrusion block 404 and the second extrusion block 405 are always against the inner wall of the eccentric groove 402 during the rotation process. The material in the eccentric groove 402 is again pumped into the reversing mechanism a through the second through hole a2 at the bottom of the reversing mechanism a and then output. The air and the cream are well mixed through the eccentric pump 4, which is beneficial to the subsequent cream whipping operation.
