[0062] The pneumatic disc assembly 9 separates the interior of the valve body 8 into two sections, each with a vent hole 901. The upper ejector pin 1102 of the adjustment knob assembly 11 presses against the top of the vent hole 901, while the lower end of the first spring 1103 abuts against the pneumatic disc assembly 9. When the adjustment knob assembly 11 is rotated, the first spring 1103 extends, gradually separating the upper ejector pin 1102 from the vent hole 901, allowing air to enter the vent hole 901 through the air inlet 1101.

[0063] The check valve assembly 10 includes a check valve body 1001 with a plurality of through-holes 1002 defined in its sidewall. The check valve body 1001 is mounted within the valve body 8, with a gap between the body and the valve body 8 allowing material to flow. A lower ejector pin 1003 is mounted within the check valve body 1001 via a second spring 1104. This lower ejector pin 1003 can be extended and retracted upward. The bottom end of the lower ejector pin 1003 extends beyond the check valve body 1001 and is connected to a limit nut 1005. The second spring 1104 forces the lower ejector pin 1003 against the bottom end of the vent hole 901, with the limit nut 1005 retaining the lower ejector pin 1003 in place. When the lower ejector pin 1003 moves downward, the second spring 1104 is compressed, the through hole 1002 opens, and the lower ejector pin 1003 is separated from the vent hole 901 . Air can pass through the vent hole 901 into the check valve assembly 10 and enter the valve body 8 from the through hole 1002 .

[0064] A feed port 801 is provided on one side of the valve body 8 and a discharge port 802 is provided at the bottom. The feed port 801 is connected to the conveying hose 402.

[0065] Reference Figure 9 、 Figure 10The specific structure of the reversing mechanism 404 is as follows: a feed channel 14 and a discharge channel 15 are provided on the reversing mechanism 404. The reversing mechanism 404 includes an inlet and outlet valve seat 12 and a reversing disk 13 mounted above and below. The inlet and outlet valve seat 12 and the reversing disk 13 are provided with corresponding channels for feeding and discharging the material, thereby forming the feed channel 14 and the discharge channel 15. The upper end of the feed channel 14 is connected to the discharge port 802 of the air control valve 403. The lower ends of the feed channel 14 and the lower ends of the discharge channel 15 are connected to the eccentric pump 405. The side end of the discharge channel 15 is connected to the whipping machine 409. The cream mixed with air is drawn into the eccentric pump 405 through the feed channel 14, where it is pumped into the discharge channel 15 and then into the whipping machine 409.

[0066] Reference Figure 11 、 Figure 12 The specific structure of the eccentric pump 405 is as follows: the eccentric pump 405 includes a pump body 16, an eccentric groove 17 is eccentrically provided on the upper surface of the pump body 16, a rotating head 18 is provided in the eccentric groove 17, a first extrusion block 19 and a second extrusion block 20 are embedded in the rotating head 18, a third spring 21 is provided between the first extrusion block 19 and the second extrusion block 20, and both ends of the third spring 21 are respectively installed inside the first extrusion block 19 and the second extrusion block 20, the first extrusion block 19 and the second extrusion block 20 are respectively against the inner walls of the eccentric groove 17, and the first extrusion block 19, the second extrusion block 20, the rotating head 18 and the upper surface of the pump body 16 are flush.

A connector base 406 is mounted above the motor mounting base 407. A connecting shaft is located within the connector base 406. The motor 408 is mounted below the motor mounting base 407. The output shaft of the motor 408 extends through the motor mounting base 407 and connects to the connecting shaft within the connector base 406 and the connector 22 at the bottom of the eccentric pump 405.

[0068] Reference Figures 13 to 20 The specific structure of the whisk 409 is that the whisk 409 includes a feeding component 23, a mixing component 24, and a discharging component 25 connected in sequence. One end of the feeding component 23 is inserted into the discharging channel 15 of the reversing mechanism 404 and fixed by a latch 26. Specifically, the reversing mechanism 404 is provided with two insertion holes for the latch 26. Positioning recesses that cooperate with the latch 26 are provided on both sides of the feeding component 23. After the latch 26 is aligned with the insertion hole and inserted, it is positioned and fits with the positioning recess to realize the connection and fixation of the whisk 409.

[0069] A first channel 2301 is provided in the feeding component 23, and end holes connected to the first channel 2301 are respectively opened at the front and rear ends of the feeding component 23. A spherical tightening member 2302 for controlling the flow of material is installed in the first channel 2301 through a fourth spring 2303. When the material enters from the end hole, the spherical tightening member 2302 is squeezed and the fourth spring 2303 is compressed to realize the flow of the material.

[0070] The mixing assembly 24 comprises an outer tube 2401, within which are arranged several mixing trays 2402 at equal intervals. A separator 2403 is positioned between adjacent mixing trays 2402. Each mixing tray 2402 is provided with a labyrinthine flow channel 2404 on its front and back surfaces for mixing the materials. A flow hole 2405 is provided in the center of each mixing tray 2402 for material circulation. The material first contacts the front side of the mixing tray 2402, flows along the labyrinthine flow channels 2404, and converges at the flow hole 2405. From there, it passes through the flow hole 2405 to the other side of the mixing tray 2402. With the cooperation of the separator 2403, the material is further dispersed and extruded along the labyrinthine flow channels 2404 on the other side. The material then contacts the next mixing tray 2402 and the next separator 2403. Through the interplay of these mixing trays 2402 and separators 2403, the material continuously circulates and is thoroughly mixed, achieving a fully whipped cream.

[0071] The whipped cream is formed and discharged through the discharge assembly 25. The discharge assembly 25 includes a second channel 2501, a third channel 2502, a fourth channel 2503, and a fifth channel 2504, which are sequentially connected. The second channel 2501 is connected to the interior of the outer tube 2401. The bottom end of the discharge assembly 25 is connected to the extrusion nozzle 27, and the fifth channel 2504 is connected to the extrusion nozzle 27.

[0072] When the small cream whipping machine of this embodiment is in operation, the adjustment knob assembly 11 is turned to open the air adjustment valve 403, the amount of air to be mixed in is adjusted, the filter mechanism 401 is placed in the cream, the motor 408 is started, and the motor 408 drives the eccentric pump 405 to rotate, so that negative pressure is generated in the pump body of the eccentric pump. The cream to be whipped is sucked into the air adjustment valve 403 through the filter mechanism 401 and the delivery hose 402. Under the influence of the negative pressure suction, the check valve assembly 10 in the air adjustment valve 403 is opened, and air is sucked into the air adjustment valve 403 and mixed with the cream. The cream mixed with air enters the eccentric pump 405 through the reversing mechanism 404. The high-speed rotation of the rotating head 18 drives the first and second extrusion blocks 19, 20 to rotate at high speed. Restricted by the eccentric groove 17, the first and second extrusion blocks 19, 20 extend and retract under the action of the third spring 21. During rotation, the first and second extrusion blocks 19, 20 always abut against the inner wall of the eccentric groove 17, squeezing the material in the eccentric groove 17 upward and pumping it out of the reversing mechanism 404. The pumped material enters the whipper 409, where it passes through the coordinated mixing disk 2402 and separator 2403, continuously circulating and being thoroughly mixed, completing the whipping of the cream. The whipped cream is then formed and discharged from the extrusion nozzle 27.
