[0021] (Three) beneficial effects

[0022] Compared with the prior art, the utility model provides a plant beverage sterilization device, which has the following

[0023] Beneficial effects:

[0024] 1、The beneficial effect of the pressure relief mechanism is that it can effectively control the pressure inside the autoclave. When the pressure inside the tank is too high, the gas will push the sealing plate against the pre-set force of the pressure spring through the pressure relief hole, causing the sealing plate to separate from the abutting sleeve and the sealing ring, releasing the excessive gas pressure and ensuring the safe release of the pressure inside the tank. This design not only ensures the safety of the equipment, but also ensures that the equipment or products will not be damaged due to excessive pressure during the sterilization process. In addition, the rotation function of the adjusting sleeve can adjust the pressure relief threshold, and by adjusting the pushing force of the pressure spring, more accurate pressure control can be achieved to meet the needs of different products for sterilization pressure. This mechanism can flexibly adjust the pressure relief according to actual needs, improving the operability and adaptability of the equipment.

[0025] 2、The beneficial effect of the limiting mechanism is that it provides precise control and safety protection for the pressure relief system. Through the cooperation of the limiting block and the limiting groove, the clamping action of the limiting block in the limiting groove limits the movement range of the adjusting sleeve, preventing inaccurate pressure control caused by excessive or insufficient adjustment. At the same time, the design of the push spring and the return spring ensures smooth movement of the limiting block and resetting of the adjusting sleeve, avoiding system instability caused by excessive adjustment. In addition, the limiting sleeve ensures that the adjusting sleeve and the pressure relief mechanism can work within a safe range under different operating conditions, enhancing the stability and durability of the device. In summary, the limiting mechanism can effectively limit the adjustment range of the adjusting sleeve, avoiding the loss of control of the pressure relief function and ensuring the safety and reliability of the equipment during long-term operation.

[0026] 3、The beneficial effect of the closing mechanism is its efficient sealing function. When the autoclave needs to be sealed, the insertion block of the sealing cover is clamped with the positioning block by rotating the rotating plate, and the sealing cover is tightened by the engagement of the rack and pinion, ensuring that the sealing gasket is fully compressed to prevent leakage. This design makes the sealing operation simple and fast, and effectively improves the sealing performance. By rotating the handle to drive the cooperation of the gear and rack, the sealing operation can be smoothly completed, reducing the difficulty of manual operation and the risk of sealing failure. Overall, the design of the closing mechanism optimizes the sealing process, enhances the operation convenience and sealing effect of the equipment, and improves the overall safety and sealing reliability of the autoclave.
