[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a sterilization processing device for medical blister packaging boxes, including a sterilization box 1. An electric valve 3 is fixedly installed on one side of the upper part of the sterilization box 1. A high-temperature steam pipe 4 is fixedly installed above the electric valve 3. The high-temperature steam pipe 4 is connected to a high-temperature steam supply device. A placement rack 11 is provided inside the sterilization box 1. The placement rack 11 includes a central column 1101 and a disc 1102. Multiple discs 1102 are provided. Multiple discs 1102 are fixedly installed on the outside of the central column 1101 and arranged vertically at intervals. The central column 1101 is rotatably connected to the sterilization box 1.

[0024] High-temperature steam is introduced into the sterilization chamber 1 through a high-temperature steam pipe 4 to sterilize the medical blister packaging boxes placed on the rack 11. Because the high-temperature steam has strong penetrability, it can reach every corner of the medical blister packaging box, thereby ensuring a stable and reliable sterilization effect and avoiding sterilization dead spots caused by obstruction or insufficient penetration during ultraviolet sterilization. In addition, the multi-disc 1102 design of the rack 11, combined with the rotation function, further enhances the contact area and uniformity between the steam and the medical blister packaging box, improving the sterilization stability.

[0025] Please see Figure 3 An annular groove is provided at the bottom of the interior of the disc 1102. A breathable mesh plate 12 is fixedly installed inside the annular groove of the disc 1102. Side holes 11021 are provided along the outer side of the annular groove inside the disc 1102. Multiple side holes 11021 are provided and arranged in annular intervals.

[0026] The annular slots and breathable mesh 12 allow steam to flow freely inside the disc, ensuring that steam can be evenly distributed to all parts of the medical blister packaging box. At the same time, the multiple annularly spaced side holes 11021 further increase the contact area between steam and the medical blister packaging box, improving the sterilization effect.

[0027] Please see Figure 1 and Figure 4 The sterilizer 1 has two side chambers 7 fixedly installed symmetrically on both sides. A fan duct 15 is fixedly installed on the upper part of the side chamber 7. A fan 16 is fixedly installed inside the fan duct 15. An air inlet grille 14 is fixedly installed on the upper part of one side of the side chamber 7. The air inlet grille 14 is connected to the fan duct 15. An electric heating tube 17 is fixedly installed inside the side chamber 7. An electric valve 3 18 is provided on one side of the lower part of the side chamber 7. The electric valve 3 18 is fixedly connected to the sterilizer 1.

[0028] The fan 16 draws in outside air through the air intake grille 14 into the fan cylinder 15. After being heated by the electric heating tube 17, the air is heated to form high-temperature air and then sent into the sterilization chamber 1 through the electric valve 18. This facilitates the drying of the medical blister packaging box after high-temperature steam sterilization, increasing its practicality.

[0029] Please see Figure 2 A gas pressure sensor 9 is fixedly installed on one side of the upper part of the sterilization chamber 1. The gas pressure sensor 9 is an SMC gas pressure sensor. A temperature and humidity sensor 10 is fixedly installed on the other side of the upper part of the sterilization chamber 1. The temperature and humidity sensor 10 is a WS300 temperature, humidity and pressure sensor.

[0030] The gas pressure sensor 9 can detect the pressure inside the sterilization chamber 1, and the temperature and humidity sensor 10 can detect the temperature and humidity inside the sterilization chamber 1. Through real-time monitoring and feedback, it helps operators adjust sterilization parameters and improve the stability and reliability of sterilization effect.

[0031] Please see Figure 2 and Figure 3 A protective ring plate 13 is fixedly installed on the outer side above the disc 1102, and a motor 8 is fixedly installed in the middle above the sterilization chamber 1. The output end of the motor 8 is fixedly connected to the central column 1101.

[0032] The protective ring plate 13 effectively protects the medical blister packaging box above the disc 1102 from falling, and the motor 8 facilitates the rotation of the placement rack 11, increasing its practicality.

[0033] Please see Figure 1 A sealing door 2 is rotatably installed at the front end of the sterilization chamber 1, and an electric valve 5 is fixedly installed on the other side above the sterilization chamber 1. An exhaust pipe 6 is fixedly installed above the electric valve 5.

[0034] Electric valve 25 is used to control the opening and closing of exhaust pipe 6, which facilitates the discharge of steam and exhaust gas from the chamber after sterilization, increasing its practicality.

[0035] Working principle: During use, the medical blister packaging boxes to be sterilized are placed in layers on multiple discs 1102 inside the sterilization chamber 1. The sealing door 2 is closed to form a sealed space. The motor 8 is started to drive the central column 1101 to rotate, so that the placement rack 11 rotates at a uniform speed. The electric valve 3 is opened, and the high-temperature steam pipe 4 injects high-temperature steam into the sterilization chamber 1. The steam permeates evenly through the annular grooves of the discs 1102 and the breathable mesh plate 12, and flows from multiple side holes 11021 to ensure that all surfaces of the packaging box are in contact with the high-temperature steam. The gas pressure sensor 9 and the temperature and humidity sensor 10 monitor the environmental parameters inside the chamber in real time. After sterilization, the electric valve 5 is opened, and the waste steam is discharged through the exhaust pipe 6. At the same time, the fans 16 on both sides are started, and the outside air enters through the air intake grille plate 14, is heated by the electric heating tube 17, and is sent into the chamber through the electric valve 3 18 to dry the packaging box with hot air, thereby achieving stable sterilization of the medical blister packaging boxes.
