[0002] Fumigation disinfection is a method of disinfection by heating a disinfectant or adding an oxidant to generate gas. By placing a solid inside a fumigation box and allowing the disinfectant gas to enter the fumigation box, the solid can be fumigated and disinfected by the gas.

[0003] The Chinese utility model patent with the patent number CN202321746205.5 discloses a solid fumigation disinfection device, which includes a fumigation box, a liquid storage bin and a mounting plate.

[0036] Combined with the attached Figure 2 and Figure 3, one side of the first air outlet pipe 62 is concentrically connected with a first piston shaft 66, and the other side of the first air outlet pipe 62 is concentrically connected with a second piston shaft 67. The first piston shaft 66 is hermetically and movably penetrated to the outside of one end of the air supply pipe 6, and the second piston shaft 67 is hermetically and movably penetrated to the outside of the other end of the air supply pipe 6. The driving assembly 5 includes a lead screw 51. One end of the lead screw 51 is connected with a mounting plate 54, and the other end of the lead screw 51 is movably connected with the air supply pipe 6. A moving seat 52 is assembled on the lead screw 51. The end of the second piston shaft 67 is connected with a connecting block 53. The moving seat 52 is connected with the connecting block 53.

A reciprocating thread structure is arranged outside the lead screw 51, so that the moving seat 52 linearly reciprocates outside the lead screw 51 to push the piston 65 to reciprocate in the air supply pipe 6.

[0037] Combined with the attached Figures 1-3 , one-way intake valves are respectively assembled outside the first intake pipe 61 and the second intake pipe 63, and one-way exhaust valves are respectively assembled outside the first air outlet pipe 62 and the second air outlet pipe 64. The one-way valves are used to better control the flow direction of the fumigation gas. An intake box 7 is installed at the bottom of the fumigation box 1. The bottom fumigation chamber is communicated with the intake box 7. The first air outlet pipe 62 is connected with the intake box 7.

[0038] Combined with the attached Figure 4 and Figure 5 , a side plate 10 is connected to the top of the placement tray 9. The side plate 10 is hermetically inserted and matched with the tray box 8. A plurality of support feet 15 are installed at the bottom of the placement tray 9. The support feet 15 are located on the inner wall of the tray box 8. A lifting shaft 13 is arranged in the middle of the fumigation box 1. The middle of the placement tray 9 is movably connected with a central shaft 12. The top of the central shaft 12 is connected with a connecting plate 14. The connecting plate 14 is connected with the lifting shaft 13. By lifting the lifting shaft 13, the placement trays 9 in a plurality of tray boxes 8 can be lifted out together, which is convenient for the placement of fumigation solids and the taking after fumigation.

[0039] Combined with the attached Figure 1 and Figure 6 , a handle is installed on the top of the box cover 3. A convex edge 11 is arranged on the side wall of the fumigation box 1.

The setting of the handle is convenient for the taking of the box cover 3.

[0040] Working principle: Place the solid in several placement trays 9, then cover the box cover 3 on the top of the fumigation box 1. By turning on the power supply, heat the disinfectant in the fumigation gas manufacturing box 2. Then control the operation of the motor 55 to make the moving seat 52 move linearly back and forth. When the moving seat 52 pushes the second piston shaft 67 to move, causing the piston 65 to move in the direction of the first piston shaft 66, the second intake pipe 63 inhales the fumigation gas in the fumigation gas manufacturing box 2. Then the second piston shaft 67 pulls the piston 65 to move in the direction of the second piston shaft 67. At this time, the second exhaust pipe 64 exhausts gas to input the fumigation gas into the bottom fumigation chamber. The fumigation gas spreads from below the exhaust hood 4 to contact the upper part of the solid. At the same time, the first intake pipe 61 inhales the fumigation gas in the fumigation gas manufacturing box 2. When the piston 65 moves towards the first piston shaft 66 again, the second intake pipe 63 inhales gas again, and at the same time the first exhaust pipe 62 exhausts gas, so that the first exhaust pipe 62 inputs the fumigation gas into several bottom fumigation chambers as shown in Figure 5 . The fumigation gas spreads from the round holes at the bottom and sides of the placement tray 9 to the solid, thereby realizing the fumigation of the top, bottom, and sides of the solid. By increasing the contact area between the fumigation gas and the solid, the fumigation efficiency of the solid is improved, the fumigation time is short, and the fumigation is more uniform.
