[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This embodiment provides a technical solution: a sterilization device for king oyster mushroom culture medium, including a shell 1 and a displacement mechanism 3;

[0024] Outer shell 1: It contains a sterilization cylinder 2. The upper side of the sterilization cylinder 2 is a placement layer, and the lower side is a water tank layer. A controller 5 is located on the front side of the outer shell 1. The input of the controller 5 is electrically connected to an external power source. A heating tube 7 is fixedly connected to the lower side of the sterilization cylinder 2. The heating end of the heating tube 7 extends into the interior of the water tank layer, and its input is electrically connected to the output of the controller 5. A level gauge 6 is located on the right side of the outer shell 1. The measuring end of the level gauge 6 extends into the interior of the water tank layer. A water supply pipe 9 is located in the middle of the right side of the outer shell 1. The left side of the water supply pipe 9 extends into the interior of the water tank layer, and its right end is externally connected to an external water supply device. The input of the level gauge 6 is electrically connected to the output of the controller 5. A top cover 4 is hinged to the upper side of the outer shell 1 via a pin. A pressure relief pipe is located on the right side of the top cover 4. A pressure relief valve 8 is located in the middle of the pressure relief pipe, and its input is electrically connected to... The output end of the controller 5 is equipped with a pressure gauge 10 on the front side of the outer casing 1. The measuring end of the outer casing 1 extends into the interior of the sterilization cylinder 2. Then, the external water supply equipment can be controlled. The external water source is discharged into the interior of the water tank layer through the water supply pipe 9. At the same time, the controller 5 needs to be controlled to operate the level gauge 6. The level gauge 6 measures the water level in the water tank layer in real time. When the water in the water tank layer reaches the specified water level, the water supply can be stopped. At this time, due to the influence of buoyancy, the arc-shaped floating plate 39 floats up. At this time, the controller 5 can be controlled to operate the heating tube 7. The heating tube 7 heats the water in the water tank layer until it boils. At this time, the boiling water will generate steam. This steam will fill the placement layer upward. When the steam is full, the water in the water tank layer will continue to boil and generate steam. At this time, the controller 5 needs to be controlled to operate the pressure relief valve 8. The pressure relief valve 8 opens, so that the interior of the sterilization cylinder 2 is kept at a normal pressure environment in real time.

[0025] The displacement mechanism 3 includes a fixed placement rack 31, a petri dish placement rack 32, an upper fastening plate 33, a clearance opening 34, a wire mesh frame 35, a vertical moving frame 36, a limiting frame 37, and a top plate 38. The fixed placement rack 31 is placed inside the placement layer. Evenly distributed petri dish placement racks 32 are fixedly connected inside the fixed placement rack 31 (the upper surface of the petri dish placement rack 32 has a V-shaped groove, and the middle of the petri dish placement rack 32 has a placement groove, which is hollow). The upper side of each petri dish placement rack 32 is hinged to an upper fastening plate 33 (the side of the upper fastening plate 33 has a V-shaped buckle). Wire mesh frames 35 are provided on the sides of the upper fastening plate 33. Clearance openings are provided on the side of each petri dish placement rack 32 facing the center of the outer shell 1. The fixed placement rack 31 has a vertically movable rack 36 slidably connected inside the opening 34. The outer surface of the vertically movable rack 36 is fixedly connected to evenly distributed limiting racks 37. The outer arc surface of the limiting rack 37 has a grooved wheel shape in the middle, and the arc surface of the grooved wheel maintains a sliding relationship with the fixed placement rack 31. The outer arc surface of the limiting rack 37 is fixedly connected to evenly distributed top plates 38 via connecting arms. The connecting arms are slidably connected to the interior of the clearance opening 34 on the same side. The displacement mechanism 3 also includes an arc-shaped floating plate 39 (the arc-shaped floating plate 39 is made of high-temperature resistant PVC board; the fixed placement rack 31, petri dish placement rack 32, upper fastening plate 33, clearance opening 34, mesh frame 35, vertically movable rack 36, limiting rack 37, and top plate 38 are all made of stainless steel). The floating plate 39 is fixedly connected to the lower side of the vertical moving frame 36. The arc-shaped floating plate 39 is located inside the water tank layer. When the sterilization device is needed, the king oyster mushroom culture medium can be placed inside the culture dish placement rack 32, and then the upper fastening plate 33 can be closed in sequence. At this time, the upper fastening plate 33 and the culture dish placement rack 32 limit the position of the king oyster mushroom culture medium. Then, the fixed placement rack 31 can be lifted and placed into the placement layer. It is worth noting that after the water in the water tank layer boils, it continuously generates bubbles. During the upward movement of these bubbles, they will touch the arc-shaped floating plate 39. The arc-shaped floating plate 39 is pushed by these bubbles and shakes continuously. It is also constrained by the arc-shaped floating plate 39, the connecting arm, and the connecting arm. Therefore, when the arc-shaped floating plate 39 is pushed, The system only moves vertically. After the arc-shaped floating plate 39 moves upward due to the impact force, it is then moved downward due to the gravity of the vertical moving frame 36. This process is repeated continuously. During this period, the top plate 38 also moves up and down, constantly pushing the culture medium in the fixed placement rack 31 so that it is not in a static state. At this time, the non-static culture medium will be fully covered by steam for all-round sterilization. It should be noted that if the water level inside the water tank drops to the specified water level, the external water supply equipment will continuously add water to the water tank to prevent the water from drying out. After the operation is completed, stop heating, open the top cover 4, take out the fixed placement rack 31, open each upper snap-fit ​​plate 33, and take out the culture medium in the petri dish placement rack 32.

[0026] The working principle of the mushroom culture medium sterilization device provided by this utility model is as follows: When the sterilization device is needed, the mushroom culture medium can be placed inside the culture dish placement rack 32, and then the upper fastening plate 33 can be closed in sequence. At this time, the upper fastening plate 33 and the culture dish placement rack 32 limit the position of the mushroom culture medium. Then, the fixed placement rack 31 can be lifted and placed into the placement layer. Then, the external water supply equipment can be adjusted, and the external water source is discharged into the water tank layer through the water supply pipe 9. At the same time, the controller 5 and the level gauge need to be adjusted. 6. The level gauge 6 measures the water level in the tank layer in real time. When the water level in the tank layer reaches the designated level, the water supply can be stopped. At this time, due to buoyancy, the arc-shaped floating plate 39 floats up. Then, the controller 5 can be adjusted to operate the heating tube 7. The heating tube 7 heats the water in the tank layer until it boils. At this time, the boiling water will generate steam. This steam will rise and fill the placement layer. When the steam fills the tank layer, the water in the tank layer will continue to boil and generate steam. At this time, the controller 5 needs to be adjusted to operate the pressure relief valve 8. The pressure relief valve 8 opens, allowing the internal pressure of the sterilization cylinder 2 to be adjusted in real time. In an atmospheric pressure environment, it is worth noting that after the water in the water tank boils, it continuously generates bubbles. These bubbles, as they move upwards, touch the arc-shaped floating plate 39. The arc-shaped floating plate 39 is propelled by these bubbles and constantly shakes. However, it is constrained by the arc-shaped floating plate 39, the connecting arm, and the connecting arm itself. Therefore, when the arc-shaped floating plate 39 is pushed, it only moves longitudinally. After moving upwards by the impact force, the arc-shaped floating plate 39 is then influenced by the gravity of the vertical moving frame 36 and moves downwards, repeating this process continuously. During this period, the top plate 3... 8 will also move up and down, constantly moving up and down to push the culture medium in the fixed placement rack 31, so that it is not in a static state. At this time, the non-static culture medium will be fully covered by steam, and a comprehensive sterilization operation will be carried out. It should be noted that if the water level inside the water tank drops to the specified water level, the external water supply equipment will continuously add water to the water tank to prevent the water from drying out. After the operation is completed, stop heating, open the top cover 4, take out the fixed placement rack 31, open each upper fastening plate 33, and take out the culture medium in the petri dish placement rack 32.

[0027] It is worth noting that the core chip of the controller 5 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The level gauge 6, heating element 7, pressure relief valve 8, and pressure gauge 10 can be freely configured according to the actual application scenario. It is recommended that the level gauge 6 be a DIT-10 digital level gauge, the heating element 7 be an SRV-3-P AC220V 1.5kW electric heating element, the pressure relief valve 8 be an SV60 steam pipeline pressure relief valve, and the pressure gauge 10 be a YTN-100ZT pressure gauge. The controller 5 controls the operation of the level gauge 6, heating element 7, and pressure relief valve 8 using methods commonly used in the prior art.
