The hydrogen peroxide discharge port 29 at the bottom of the disinfection chamber 10 is connected to a hydrogen peroxide purification solenoid valve 33 through a corrosion-resistant hose.

The concentration of hydrogen peroxide is diluted and effective treatment and discharge work is achieved through the opening and closing of the cycle of hydrogen peroxide discharge and air intake dilution.

[0041] In this embodiment, the portable mechanism is a structure used to make the entire device convenient to carry and move.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the portable mechanism includes a disassembly plate 41 abutting against the bottom of the packing box 1, and the left and right sides of the packing box 1 are rotatably connected with a rotating rod 42 through a bearing, and a connecting piece 43 is fixed to the end of the rotating rod 42 away from the packing box 1, and an adjustable strap 44 is provided between the outer sides of the two connecting pieces 43, and the left and right sides of the packing box 1 are fixed with a connecting block 45, and the top of the connecting block 45 abuts with a knob 46, and a rotating rod 47 is fixed to the bottom of the knob 46, and two limit blocks 48 are fixed to the outer side of the rotating rod 47, and two slots 49 are provided at the bottom of the connecting block 45, and four plug blocks 50 are fixed on the top of the disassembly plate 41, and a limit slot 51 is provided on the outer side of the plug block 50, and two movable cavities 52 respectively connected to the corresponding two slots 49 are provided inside the connecting block 45, and four movable slots 53 are provided at the bottom of the disassembly plate 41, and the inner side of the movable slot 53 is rotatably connected with a walking wheel 54 through a rotating shaft.

[0043] It should be noted that a rotating groove is provided on the top of the connecting block 45 for the rotating rod 47 to be inserted and rotated. The bottom end of the rotating rod 47 is rotatably connected through a damping shaft and the inner bottom wall of the rotating groove, so that the rotating rod 47 can be slowly rotated through the damping shaft, and under the action of damping, it can only rotate under human intervention, thereby ensuring the stability of the connection. The two plug-in blocks 50 on the same side can be respectively inserted into the inner sides of the corresponding two slots 49, and the basic positioning of the connecting block 45 can be achieved through the plug-in cooperation between the plug-in blocks 50 and the slots 49.

[0044] In addition, the two limiting grooves 51 on the same side are arranged in a circle with the corresponding rotating rod 47 as the center, the side of the limiting groove 51 close to the rotating rod 47 is open, and the opposite sides of the corresponding two limiting grooves 51 are both open, and the two movable cavities 52 on the same side are arranged in a circle with the corresponding rotating rod 47 as the center, the limiting block 48 is slidably connected to the inside of the corresponding movable cavity 52, and the limiting block 48 can be rotated to the inside of the corresponding limiting groove 51 through the corresponding movable cavity 52, so that the limiting block 48 can be rotated to the inside of the corresponding limiting groove 51 under the rotation action of the rotating rod 47 to limit the insert block 50, and the bottom of the walking wheel 54 extends to the outside of the corresponding movable groove 53, so that the walking wheel 54 can support and move the disassembly and assembly plate 41.

[0045] The working principle of the above embodiment is:

[0046] (1) When it is necessary to carry the sterilization device to the rescue site to disinfect the relevant equipment, the packaging box 1 is placed on the top of the disassembly and assembly plate 41, and the plug block 50 is inserted into the inner side of the corresponding slot 49. The knob 46 is turned to rotate the rotary rod 47, and the corresponding two limit blocks 48 are respectively rotated to the inner side of the corresponding limit slot 51, so that the plug block 50 can be limited. Under the action of damping, the knob 46 will not rotate easily without manual rotation, so that the position of the connecting block 45 is positioned, so that the packaging box 1 can be stably placed on the top of the disassembly and assembly plate 41. By pulling the adjustable strap 44, the packaging box 1 can be driven to move under the action of the walking wheel 54. The packaging box 1 can also be tilted or carried in the hand through the adjustable strap 44, and the packaging box 1 can also be carried by hand under the action of the handle 6, so that the staff can carry it to the work place.

[0047] (2) During sterilization, the PLC control system 27 is controlled through the operation interface 25 to start the heating plate 16 for heating, in preparation for the evaporation of the hydrogen peroxide liquid, and the heating tube 32 is controlled to heat the disinfection chamber 10, so that the temperature of the heating plate 16 is controlled within the range of 145-150 degrees Celsius, and the temperature inside the disinfection chamber 10 is controlled below 45 degrees Celsius, completing the preparation link, starting the hydrogen peroxide liquid solenoid valve 13 to connect the pipeline so that the hydrogen peroxide liquid can circulate normally, starting the peristaltic pump 14, pumping the hydrogen peroxide liquid into the hydrogen peroxide generator 15 and being heated and evaporated by the heating plate 16, and then the hydrogen peroxide diffusion fan 17 cooperates with the multi-airflow distribution port 18 to evenly diffuse it into the disinfection chamber 10, and then the hydrogen peroxide detection probe 30 performs real-time detection of its concentration, humidity and temperature to determine whether it has reached a saturated state, and the hydrogen peroxide liquid is controlled by real-time monitoring of the hydrogen peroxide detection probe 30. The extraction and delivery speed is set so that the hydrogen peroxide gas in the disinfection chamber 10 can be continuously maintained in a saturated state, so as to achieve continuous coverage of the surface of the sterilized equipment and continuous elimination of microorganisms. After the disinfection is completed, the hydrogen peroxide liquid solenoid valve 13 is closed to prohibit the hydrogen peroxide liquid from passing through, and the peristaltic pump 14 and the hydrogen peroxide diffusion fan 17 are stopped at the same time, and the air circulation solenoid valve 37 and the hydrogen peroxide purification solenoid valve 33 are started to allow the hydrogen peroxide gas in the disinfection chamber 10 to circulate. At the same time, the hydrogen peroxide purification fan 35 and the air flow fan 39 are started to dilute the hydrogen peroxide solubility in the disinfection chamber 10. The microorganisms in the air holes can be filtered through the air filter element 40 so that they will not contaminate the equipment in the disinfection chamber 10. At the same time, the hydrogen peroxide gas is decomposed by the hydrogen peroxide filter element 36 in the hydrogen peroxide filter 34 to form water and oxygen, thereby ensuring the safety of the external working environment and the staff.
