[0030] Example:

[0031] like Figure 1 The main body of the sterilization cabinet has a square columnar appearance and is provided with a square sterilization chamber. The upper cover 1 can be opened and can be locked and sealed after the risk fabric is placed in it to achieve sealed compression and disinfection of the risk fabric in the sterilization chamber.

[0032] like Figure 2The main support structure of the sterilizing cabinet mainly consists of the following structures: a cabinet support bottom plate 13, a motor fixed support 12, four guide rods 7, an upper fixed support plate 5, an upper cover 1, a locking handle 3, and four universal wheels 22. A motor fixed support is installed in the middle of the cabinet support bottom plate 13, and four guide rods 7 are symmetrically installed at the four corners; the upper ends of the four guide rods 7 are connected by a horizontal upper fixed support plate to keep the four guide rods 7 vertical; the upper cover 1 is hingedly installed on one side of the upper fixed support plate 5 and can be opened upward. When the upper cover 1 is closed, the locking handle 3 at the front end of the upper cover 1 can be pressed down to lock it, thereby providing a downward support reaction force during the compression process. Polytetrafluoroethylene insulation material is padded between the upper cover 1 and the upper heating plate 2 to reduce heat dissipation. Four universal wheels are installed at the bottom of the cabinet to facilitate the movement of the sterilizing cabinet. The above main support adopts a frame structure design to provide guarantee for the structural stability and safety of the sterilization process.

[0033] like Figure 3 The sterilization cabinet controls the compression process and sterilization time through the numerical control panel 4 located on the upper cover 1, and has a preset parameter saving function; the sterilization cabinet shell 23 is made of lightweight and high-strength plastic, which protects the internal components of the cabinet.

[0034] like Figure 4The lifting mechanism is mainly composed of the following structures: two electric push rods 11, two scissor drive arms 8, two connecting beams 10, a fixed frame 6, a movable plate 19, four directional linear sleeves 20, four piston rods 16 and a lower heating plate 14; the piston rod is a connecting rod with a smooth surface. The main motors of the two electric push rods 11 are symmetrically installed on the motor fixed support 12, and the two scissor drive arms 8 are symmetrically arranged between the upper fixed frame 6 and the lower movable plate 19. The top of the electric push rod 11 is connected to the middle of the scissor drive arm 8 through the connecting beam 10, which can control the lower movable plate 19 to move up and down. Specifically, the scissor drive arm 8 includes: an x-shaped and hinged first arm and a second arm and a short rod hinged to the end of the arm; the hinge of the first arm and the second arm is fixed to the movable beam 10; the short rod on the arm close to the fixed frame 6 and the short rod close to the movable plate 19 are respectively hinged to the fixed frame 9 and the movable plate 19. Four piston rods 16 are symmetrically mounted on the movable plate 19, and the upper ends of the piston rods 16 are connected to the four corners of the lower heating plate 14 respectively. The risk fabric can be vertically compressed by pushing the lower heating plate 14, and the air in the risk fabric is discharged to the bottom of the lower heating plate through the gap between the lower heating plate 14 and the inner wall of the cabin 9; four directional linear sleeves 20 are symmetrically arranged at the four corners of the movable plate 19, which can slide coaxially with the four guide rods 7 in the cabinet to ensure that the lower heating plate 14 remains horizontal during movement. The connecting beam 10 also passes through the guide rod 7 and can slide along the guide rod 7. The fixing parts are symmetrically arranged at the four corners of the fixed frame 6 to fix the fixed frame 6 on the guide rod 7. The above scissor-type transmission and directional compression structural design form amplifies the transmission stroke and improves the transmission stability, so that the equipment has high space utilization and quiet operation.

[0035] like Figure 5The sterilization chamber in the sterilization cabinet is mainly composed of the following structures: an upper heating plate 2, a chamber body 9, a layer of heat-conducting aluminum sheet 21, four inner wall heating sheets 17, a heating fan 15, four sliding sealing sleeves 18 and a lower heating plate 14. The cabin 9 is connected and fixed to the upper fixed frame 6 through a connecting piece, and the upper heating plate 2 is fixed to the lower surface of the upper cover 1. The lower surface of the upper cover 1 has a sealing groove that matches the upper end of the cabin 9, and can achieve end face sealing with the cabin 9 when closed; since the thermal conductivity of the risk fabric after compression is greatly improved, the upper heating plate 2 and the lower heating plate 14 can quickly conduct heat to the risk fabric; the cabin 9 is made of polytetrafluoroethylene heat-resistant insulation material, and the inner surface is lined with a heat-conducting aluminum sheet 21; the lower heating plate 14 divides the cabin 9 into an upper space and a lower space, wherein four heating sheets 17 are installed in the lower space, which can realize heating of the cabin 9 and minimize heat conduction to the outside of the cabin; the heating fan 15 fixed at the bottom of the cabin 9 can perform rapid circulating convection heating on the air with risk aerosol in the cabin 9; four sliding sealing sleeves 18 are arranged at the four corners of the bottom of the cabin 9, which can realize sliding sealing during the upward push of the piston rod 16. The above heating, insulation and sealing designs realize efficient sterilization of risky fabrics and their internal risky aerosols, making the equipment have the advantages of low heat loss, fast sterilization and no dead angle.

[0036] The working principle and operation steps of the sterilization cabinet are as follows:

[0037] 1. When using the sterilizer, place it on a stable surface and turn on the power supply, lock the universal wheels 22 to keep it stable; start the main switch on the numerical control panel 4 and press the reset function key to ensure that the lower heating plate 14 is at the lowest position; open the locking handle 3 and lift the upper cover 1, put the risk fabric to be treated into the cabin 9, close the upper cover 1 and press the locking handle 3;

[0038] 2. Press the sterilization function key on the numerical control panel 4 (at the same time, the upper cover 1 of the sterilizer is locked and cannot be opened), control the two electric push rods 11 to raise the movable plate 19 and the four piston rods 16 through the two scissor drive arms 8, and the lower heating plate 14 is driven to move upward and squeeze the risk fabric; when the risk fabric is squeezed to a certain thickness between the lower heating plate 14 and the upper heating plate 2, the stop switch stops the lower heating plate 14 from moving. At this time, the air carrying the risk aerosol in the risk fabric is squeezed and discharged to the space below the lower heating plate 14 through the gap between the lower heating plate 14 and the heat-conducting aluminum sheet 21 on the inner wall of the cabin 9;

[0039] 3. The lower heating plate 14, the heating elements inside the upper heating plate 2 and the inner wall heating plate 17 start heating, and begin to heat the extruded risk fabric and the inner wall aluminum plate 21 of the inner cabin. At the same time, the heating fan 15 at the bottom of the cabin 9 starts to perform circulating convection heating on the risk aerosol in the cabin 9.

[0040] 4. The sterilization temperature and sterilization time can be set through the numerical control panel 4, or directly use the preset stored setting parameters. The maximum sterilization temperature is in the range of 80-100°C. After the temperature in the cabin 9 reaches the maximum setting temperature, the temperature is maintained for 3-5 minutes to ensure that the risk fabrics and risk aerosols are completely sterilized. During the sterilization process, the cabin 9 remains airtight, realizing the isolation and sterilization of the risk fabrics and aerosols in the cabin 9;

[0041] 5. After the sterilization is completed, the heating plate 17 and the heating fan 15 automatically stop working, and the two electric push rods 11 drive the movable plate 19 and the piston rod 16 to move downward through the scissor-type transmission arm 8, so that the lower heating plate 14 descends.

[0042] 6. When the temperature in the cabin 9 drops below 40°C, the locking handle 3 is unlocked, the upper cover 1 can be opened, and the sterilized fabric can be taken out. The disposable fabric will no longer be used after sterilization, and the reusable fabric can continue to be used. The temperature of the sterilization process will not affect the subsequent use of the reusable fabric.

[0043] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
