Detailed Implementation

[0056] The following detailed description, in conjunction with the accompanying drawings, illustrates the implementation of this utility model. However, these descriptions do not constitute a limitation of the present utility model and are merely illustrative. Furthermore, the advantages of this utility model will become clearer and easier to understand through this description.

[0057] This utility model relates to a sterilization cabinet for edible fungi with a locking mechanism. It achieves high-pressure sealing by fastening the cabinet body and door together, and then filling the silicone rubber strip ring within the rubber strip groove with high-pressure gas to form a high-pressure sealing ring. This mechanism is simple in structure, stable and reliable, provides excellent high-pressure sealing, and is easy to operate.

[0058] like Figure 1 As shown, the locking mechanism of this edible mushroom sterilization cabinet is adapted to a rectangular box-type cabinet structure with a square door 5. The door hinges 2 and the saw-shaped locking device 1 connect the door 5 to both sides of the sterilization cabinet body 4, representing a traditional door opening and closing combination. The door hinges 2 are evenly distributed at the top, middle, and bottom; see [details omitted for brevity]. Figure 4 and Figure 5 Each hinge has four hinge fixing blocks 21 fixed to the frame of the sterilizer body 4, and the pad 24 fixed to the frame of the cabinet door 5. The thrust ball bearing 25 serves to bear weight and rotate. The saw-shaped locking device 1 covers the entire edge of the cabinet door opening, with 12 bushings 12 fixed to the frame of the sterilizer body 4, the saw-shaped fixed locking buckle 15 fixed to the frame of the cabinet door 5, and the saw-shaped movable locking buckle 11 being a rotatable component.

[0059] like Figure 2As shown, the inner side of the cabinet door 5 is a pressure-bearing inner panel 50, and a groove 51 around it serves to install and fix the silicone strip 52, and can limit the expansion of the silicone strip 52 to both sides.

[0060] like Figure 3 As shown, simply lift the latch handle 13 along with the latch movable block 16 upwards, and then pull the latch handle 13 along with the saw-shaped movable latch 11 outwards to unlock the saw-shaped movable latch 11 from the saw-shaped fixed latch 15, allowing the cabinet door 5 to open. To close the door, simply push the cabinet door 5 closed, then rotate the latch handle 13 along with the saw-shaped movable latch 11 inwards to engage the saw-shaped movable latch 11 with the saw-shaped fixed latch 15. Then lower the latch handle 13, locking the latch movable block 16 inside the latch fixed block 17 to close the door.

[0061] The cut edge of the saw-shaped fixed locking buckle 15 is rounded, which can easily achieve the tight locking operation between the saw-shaped movable locking buckle 11 and the saw-shaped fixed locking buckle 15.

[0062] The specific operation process of this utility model is as follows:

[0063] Closing the door: After pushing the sterilization rack containing the sterilization sticks into the sterilization cabinet, push the cabinet door 5 to close the cabinet door 5 and the main body of the sterilization cabinet 4 as much as possible. Turn the door latch handle 13 inward to lock the saw-shaped movable lock 11 and the saw-shaped fixed lock 15 tightly. Then, lower the door latch handle 13 to lock the door latch movable block 16 inside the door latch fixed block 17 to complete closing the door.

[0064] Sterilization: After closing the door, turn on the air and power to the sterilizer, adjust the pressure regulating filter to make the output air pressure 0.4-0.5 MPa, and then turn on the inflation switch of the silicone rubber strip 52. After the silicone rubber strip 52 inflates, the gap between the door 5 and the main body 4 of the sterilizer will be sealed by the expanded silicone rubber strip 52. Then, steam is introduced to start the sterilization process.

[0065] Pressure Relief and Door Opening: After sterilization, the steam outlet pipe remains open to release steam and condensate from the main body 4 of the sterilizer. After the pressure inside the cabinet is released, open the exhaust switch of the silicone rubber strip 52 to release the gas inside the silicone rubber strip 52. Once the steam temperature inside the cabinet has dropped to a suitable level, lift the door latch handle 13 along with the door latch movable block 16 upwards, and then pull the door latch handle 13 along with the saw-shaped movable lock 11 outwards. This will release the tight fastening between the saw-shaped movable lock 11 and the saw-shaped fixed lock 15, allowing the cabinet door 5 to be opened.

[0066] All other unspecified parts belong to the prior art.
