[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to Figure 1-7 , a vaporized hydrogen peroxide sterilization device, including a base 1 and a transfer tank 2. The transfer tank 2 is rotatably connected to the top of the base 1. A spray pipe 5 is provided at the bottom of the transfer tank 2. A limit plate 14 is fixedly connected to one side of the top of the base 1. A pressure shell 3 is slidably connected to one side of the limit plate 14, and the pressure shell 3 is sleeved above the transfer tank 2. A pressure rod 4 is fixedly connected to the outer wall of the top of the pressure shell 3, and a first steam inlet pipe 7 is inserted into the top of one side of the pressure shell 3. One end of the first steam inlet pipe 7 away from the pressure shell 3 is fixedly connected to a steam inlet 9. A rotating seal bearing 35 is inserted into the middle position of the top of the transfer tank 2. The inner wall of the rotating seal bearing 35 is fixedly connected to a second steam inlet pipe 29. The bottom of the second steam inlet pipe 29 communicates with the inside of the transfer tank 2. The same bellows 30 is fixedly connected between the first steam inlet pipe 7 and the second steam inlet pipe 29. A rotating cylinder 28 is fixedly connected to the middle position of the outer wall of the top of the transfer tank 2. The second steam inlet pipe 29 is located inside the rotating cylinder 28. Threads are provided on the outer wall of the rotating cylinder 28, and an internal thread sleeve 32 is threadedly connected to the outside of the rotating cylinder 28. A pressure ring 33 is fixedly connected to the outer wall of the internal thread sleeve 32. Hangers 31 are fixedly connected to the tops of both sides of the pressure ring 33. The tops of the two hangers 31 are fixedly connected to the inner wall of the top of the pressure shell 3. A return spring 34 is fixedly connected to the bottom of the pressure ring 33. The bottom of the return spring 34 is rotatably connected to the outer wall of the top of the transfer tank 2.

[0030] In the present invention, an outer casing 8 is sleeved outside the first steam inlet pipe 7. One end of the outer casing 8 is fixedly connected to the outer wall of the top of the corrugated pipe 30, and the other end of the outer casing 8 is fixedly connected to the pressure casing 3. When the pressure casing 3 moves up and down, the outer casing 8 moves accordingly and drives the corrugated pipe 30 to expand and contract. At the same time, the outer casing 8 plays a role in protecting and supporting the first steam inlet pipe 7. The outer casing 8 enhances the structural strength of the first steam inlet pipe 7 and prevents it from being damaged by external forces during use. At the same time, the connection method of the outer casing 8 with the corrugated pipe 30 and the pressure casing 3 ensures the stability of the entire steam inlet system. And under the protection of the outer casing 8, the corrugated pipe 30 can better play the functions of sealing and expansion and contraction.

[0031] In the present invention, two symmetrically arranged guide rails 16 are fixedly connected to the outer wall of the pressure casing 3 near one side of the limit plate 14. The limit plate 14 is slidably connected between the two guide rails 16. The limit plate 14 provides precise sliding guidance for the guide rails 16 to ensure the stable movement of the guide rails 16 and the pressure casing 3 in the vertical direction, which helps to improve the accuracy of the operation of the entire sterilization device.

[0032] In the present invention, the same cross beam 17 is fixedly connected to the tops of the two guide rails 16. An external thread sleeve 18 is fixedly connected to the middle position of the top of the cross beam 17. A screw rod 19 is threadedly connected inside the external thread sleeve 18. The bottom end of the screw rod 19 extends between the two guide rails 16. The top of the screw rod 19 is fixedly connected to a knob 20. The bottom of the screw rod 19 is rotatably connected to a lifting block 21. When the knob 20 is rotated, the screw rod 19 rotates inside the external thread sleeve 18, driving the lifting block 21 to move up and down, and the height of the lifting block 21 can be precisely controlled, so as to realize the precise adjustment of the movable range of the guide rails 16 and the pressure casing 3, and further realize the precise adjustment of the rotation range of the spray pipe 5.

[0033] In the present invention, a rubber strip 15 is fixedly connected to the top of the limit plate 14, and the rubber strip 15 is located directly below the lifting block 21. The rubber strip plays a role of anti-collision and buffering between the limit plate 14 and the lifting block 21.

[0034] In the present invention, an indicating scale 23 is provided on the outer wall of one of the guide rails 16. A pointer 22 is fixedly connected to one side of the lifting block 21 close to the indicating scale 23. When the lifting block 21 moves up and down as the screw rod 19 rotates, the pointer 22 will point to the corresponding position on the indicating scale 23, which is convenient for the user to directly read the moving stroke of the guide rails 16 and the pressure casing 3, and is convenient for precisely adjusting to the required height, and the device can be quickly and accurately set in different sterilization scenarios.

[0035] In the present invention, a solenoid valve 6 is provided in the middle of the spray pipe 5, and the on-off of the spray pipe 5 is controlled by the solenoid valve 6.

[0036] In the present invention, a bottom plate 24 is fixedly connected to one side of the base 1 away from the nozzle 5. At the top of the side of the bottom plate 24 close to the base 1, two symmetrically arranged brackets 36 are fixedly connected. A same pedal 25 is rotatably connected between the two brackets 36. An anti-slip pad 26 is adhesively attached to the top of the pedal 25. A same foot pedal spring 27 is fixedly connected between the pedal 25 and the bottom plate 24. When the user operates the pressure lever 4, the foot steps on the pedal 25 to enhance the stability of the base 1. The anti-slip pad 26 increases the friction between the foot and the pedal 25 to prevent slipping and improve the operation safety.

[0037] In the present invention, a pressing column 38 is fixedly connected to the bottom of the pedal 25. A button switch 37 adapted to the pressing column 38 is fixedly connected to the top of the bottom plate 24. The pressing component of the button switch 37 is on the rotation path of the pressing column 38. When the pedal 25 is stepped on, the pressing column 38 moves downward and presses the button switch 37 to make the button switch 37 in a triggered state.

[0038] In the present invention, the button switch 37 is connected in series to the power circuit of the solenoid valve 6. When the pedal 25 steps on the pressing column 38, the foot pedal spring 27 is compressed, the button switch 37 is triggered, the circuit is conducted, and the solenoid valve 6 conducts the nozzle 5. When the user releases the pedal 25, the foot pedal spring 27 drives the pressing column 38 to reset, the button switch 37 is not triggered, the circuit is disconnected, and the solenoid valve 6 stops working. The solenoid valve 6 disconnects the nozzle 5, directly associating the operation of the pedal 25 with the control of the nozzle 5, simplifying the control logic, improving the operation coherence and reliability, and the power supply of the solenoid valve 6 can be independently controlled by the button switch 37, facilitating other manual controls when the operation of the pedal 25 is not required.

[0039] In use, connect the steam inlet 9 to the pressure storage device storing vaporized hydrogen peroxide. The vaporized hydrogen peroxide reaches the inside of the transfer tank 2 through the first steam inlet pipe 7, the bellows 30, and the second steam inlet pipe 29, and is ejected outward through the nozzle 5 at the bottom of the transfer tank 2. The bellows 30 can expand and contract to adapt to the up and down displacement of the pressure housing 3. In use, press down the pressure housing 3 through the pressure rod 4, driving the hanger 31, the pressure ring 33, and the internally threaded sleeve 32 to move downward synchronously. The rotating cylinder 28 and the transfer tank 2 rotate under the influence of the threads, and the nozzle 5 can eject vaporized hydrogen peroxide outward in a rotating state. During the process of pressing down the pressure rod 4, the return spring 34 is compressed synchronously. When the pressure rod 4 can no longer be pressed down, the operator stops applying downward pressure to the pressure rod 4 but still holds the pressure rod 4. The return spring 34 pushes up the pressure ring 33, the internally threaded sleeve 32, the hanger 31, and the pressure housing 3. Since the pressure rod 4 is still held, it can be ensured that the pressure ring 33, the internally threaded sleeve 32, the hanger 31, and the pressure housing 3 do not rotate. Therefore, the rotating cylinder 28, the transfer tank 2, and the nozzle 5 rotate in the reverse direction and reset under the action of the threads. Repeating the process of pressing down the pressure rod 4 and the return of the return spring 34 can achieve continuous rotation and ejection of vaporized hydrogen peroxide by the nozzle 5.

[0040] As described above, only the preferred specific embodiments of the present invention are given, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
