[0019] Beneficial effects
[0020] The technical solution provided by this invention has the following advantages compared with known public technologies:
[0021] In this invention, the structure of the juicer's feeding section, namely the inlet and balance pipe assembly, is designed as a storage-type heightening device. The crushing rod in the feeding cylinder is designed as a symmetrical double-blade design, using uncrushed material to seal the flow of the juicer's inlet. Adding an appropriate amount of RO hydrogen-rich water forms a feeding liquid sealing chamber. In the sealing assembly, an operable hydraulic cylinder structure drives a sealing plate structure on one side to seal the fruit at the top of the inlet, achieving bottom space sealing adjustment. In the bottom feeding cylinder, drive motor structures on both sides drive the rotating rod-crushing rod to rotate. A partition plate structure is set on the outside of the crushing rod. The partition plate can disperse the fruit to both ends and contact the crushing rod, so that the fruit is crushed in the feeding cylinder, improving the crushing effect.
[0022] In this invention, the diaphragm structure set in the balance tube assembly can be adjusted by the air pressure between the juicing cylinder and the feeding cylinder. The diaphragm can move inside the balance tube, and the pressure gauges on both sides can display the internal air pressure in real time, thus achieving a sealing function. The juice discharge vortex-type closed chamber reduces foam generated by impact.
[0023] In this invention, a nitrogen filling component is provided at the top of the juicing cylinder and the mounting plate. The user can connect the connecting pipe to an external pipeline. When the internal gas pressure is too high, gas enters the connecting pipe through the air hole, stretches the spring, and drives the baffle and plug structure upward. The gap between the plug and the inner ring becomes larger, and the gas can escape quickly, which can play an automatic adjustment function. The user can add sufficient nitrogen through the connecting pipe to play an adjustment function.
[0024] In this invention, the sealing ring-cooling coil structure allows the sealing ring inside the juicing cylinder to make close contact with the threaded juicing ring on the rotating cylinder, thus achieving the function of sealing the juicing process. Furthermore, it can be combined with the nitrogen filling component structure to isolate external air, ensuring that the oxidation rate of the fruit and juice is reduced during the juicing process, improving the drinking taste, and protecting the effective ingredients from loss or reduction.

It can also be used in conjunction with the nitrogen filling component 10 structure to isolate the external air, ensuring that the oxidation rate of the fruit and juice is reduced during the juicing process, and improving the drinking taste.
[0040] The juicer's feeding section, including the inlet 6 and the balance tube assembly 8, is designed as a storage-type heightening device. The crushing rod 55 in the feeding cylinder 5 is designed as a symmetrical double-blade design, using uncrushed material to seal the flow of the juicer's inlet. Adding an appropriate amount of RO hydrogen-rich water forms a feeding liquid sealed chamber. In the sealing assembly 7, an operable hydraulic cylinder 72 drives a sealing plate 73 on one side to seal the fruit at the top of the inlet 6, achieving bottom space sealing adjustment. In the bottom feeding cylinder 5, drive motors 52 on both sides drive the rotating rod 521 and the crushing rod 55 to rotate. A partition plate 54 is set on the outside of the crushing rod 55. The partition plate 54 can disperse the fruit to both ends and contact the crushing rod 55, allowing the fruit to be crushed in the feeding cylinder 5, improving the crushing effect.
[0041] The two sets of partition plates 54 are trapezoidal structures, and a partition plate 53 is fixed in the middle of the two sets of partition plates 54.
