Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: an electric heating pressure steam sterilizer, including an electric heating pressure steam sterilization tank 1, a tank cover 3 is movably installed on the top of the electric heating pressure steam sterilization tank 1, a lifting mechanism is arranged outside the tank cover 3, and the tank cover 3 can be lifted upward and slid downward by using the lifting mechanism to realize the movement of the tank cover 3, which is convenient to put items into the electric heating pressure steam sterilization tank 1 for subsequent sterilization work. Moreover, a plurality of support rods 5 are fixedly connected to the bottom of the tank cover 3, and a support ring 6 is fixedly connected to the outside of the plurality of support rods 5 near the bottom end. A plurality of circular frames 7 are arranged on the top of the support ring 6, the plurality of circular frames 7 are stacked, and a support net 9 is fixedly installed in the inner cavity of each of the plurality of circular frames 7. By using the cooperation of the circular frames 7 and the support net 9, items can be put into the electric heating pressure steam sterilization tank 1, and after subsequent sterilization is completed, they can be taken out conveniently, and the operation is convenient.

[0024] Please refer to Figure 1 , Figure 2 and Figure 5, the lifting mechanism includes several side frames 10 which are respectively fixedly connected to the outer wall of the electrothermal pressure steam sterilizer 1. At the bottom of the inner walls of several side frames 10, motors 11 are fixedly connected. The motors 11 provide power. At the top of the motors 11, screws 12 are fixedly connected. The top ends of the screws 12 are rotatably connected to the tops of the side frames 10. A threaded sleeve 13 is threadedly connected to the outside of the screw 12. A connecting bar 16 is fixedly connected to the outside of the threaded sleeve 13. Vertical grooves 14 are formed in the side walls of the side frames 10. One sides of several connecting bars 16 away from the threaded sleeve 13 respectively penetrate through the corresponding vertical grooves 14 and are commonly fixedly connected to a fixing ring 17. The fixing ring 17 is sleeved and fixedly installed on the outside of the tank cover 3. By driving the motor 11 to drive the screw 12 to rotate, the screw 12 drives the threaded sleeve 13 on the outside to move. The threaded sleeve 13 drives the connecting bar 16 to move. Multiple connecting bars 16 commonly drive the fixing ring 17 to move. The fixing ring 17 drives the tank cover 3 to move, realizing the lifting operation of the tank cover 3, and the operation is convenient.

[0025] Please refer to Figure 5 , a limiting block 15 is fixedly connected to the outer wall of the threaded sleeve 13 near the bottom. One side of the limiting block 15 away from the threaded sleeve 13 extends into the inner cavity of the vertical groove 14, and the limiting block 15 is slidably connected to the inside of the vertical groove 14. By using the cooperation of the limiting block 15 and the vertical groove 14, the up-and-down movement track of the threaded sleeve 13 is limited, thereby ensuring the stability of components such as the connecting bar 16 and even the tank cover 3.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 , the inner cavity of the tank cover 3 is hollow, and a communicating pipe 4 is inserted and installed at the top of the tank cover 3. A control valve 18 is installed on the communicating pipe 4. By using the communicating pipe 4 to connect the electrothermal pressure steam sterilizer 1 with an external negative pressure device, the steam generated inside the electrothermal pressure steam sterilizer 1 is pumped out by the negative pressure device, avoiding the formation of water droplets in the electrothermal pressure steam sterilizer 1 and re - contacting the items, causing secondary pollution to the items.

[0027] Please refer to Figure 3 and Figure 4 , a limiting ring 8 is fitted and installed in each of several circular frames 7. The bottom limiting ring 8 is fixedly connected to the top of the support ring 6, and several top limiting rings 8 are respectively fixedly connected to the inner walls of the corresponding circular frames 7. By using the setting of the limiting ring 8, the installation of the circular frames 7 and the support ring 6 is stable, and the installation between multiple circular frames 7 is stable, making the subsequent sterilization work more stable.

[0028] Please refer to Figure 1 , the electrothermal pressure steam sterilizer 1 is fixedly connected to a base 2 at the bottom. The base 2 is circular - ring - shaped, and the overall support operation of the electrothermal pressure steam sterilizer 1 is realized by using the base 2.

[0029] Please refer toFigure 3 and Figure 4 The inner diameter of the support ring 6 is set to be smaller than that of the circular frame 7, and the outer diameter of the support ring 6 is set to be larger than that of the circular frame 7. Such a setting makes the installation operation between the circular frame 7 and the support ring 6 convenient.

[0030] Working principle: When this application is in use, first connect the connecting pipe 4 to an external negative pressure device, open the control valve 18, and synchronously drive multiple motors 11, so that the multiple motors 11 respectively drive the corresponding screws 12 to rotate. The screws 12 drive the threaded sleeves 13 to move upward. The threaded sleeves 13 drive the corresponding connecting bars 16 to move upward. The multiple connecting bars 16 jointly drive the fixed ring 17 to move upward. The fixed ring 17 drives the tank cover 3 to move upward. The tank cover 3 drives the multiple support rods 5 at the bottom to move upward. The multiple support rods 5 jointly drive the support ring 6 to move upward. The support ring 6 drives the multiple circular frames 7 at the top to move upward. After moving to an appropriate height, turn off the multiple motors 11. At this time, the staff can remove the multiple circular frames 7 from the top of the support ring 6, place the items to be sterilized inside the multiple circular frames 7, and use the support mesh 9 inside the circular frames 7 to support and hold the items. Then stack the circular frames 7 containing the items on the top of the support ring 6. At this time, drive the multiple motors 11 again to drive the tank cover 3 to reset, so that the circular frames 7 containing the items and the support ring 6 move back into the electrothermal pressure steam sterilizer 1. After the tank cover 3 is reset, turn off the multiple motors 11. At this time, use the electrothermal pressure steam sterilizer 1 to complete the sterilization operation. A large amount of steam generated during the sterilization process is sucked out of the electrothermal pressure steam sterilizer 1 by the negative pressure device, preventing water droplets from forming inside the electrothermal pressure steam sterilizer 1 and coming into contact with the items again, causing secondary contamination to the items. After the items are sterilized, stop the sterilization work, drive the multiple motors 11 to move the tank cover 3 upward, repeat the above operation to remove the circular frames 7, and then take out the items inside the circular frames 7. The operation is convenient.
