[0021] Based on Embodiment 2, an atomization operation is performed. The atomization assembly is located within the lifting movable plate 3. The atomization assembly includes a flow guide hood 15, two atomizing tubes 18, and four liquid outlet tubes 24.

A central transfer cylinder 20 is vertically mounted on several horizontal support arms. The central transfer cylinder 20 is movably connected to a central shaft 16. A liquid chamber 21 is opened at the lower end of the central transfer cylinder 20. A liquid delivery hose 22 is inserted into the upper end of the liquid chamber 21 and passes through one of the horizontal support arms, connecting to the lower end of the liquid storage tank 11. Four fixed arms 23 are horizontally symmetrically arranged on the four sides of the central transfer cylinder 20. Four liquid outlet pipes 24 are horizontally arranged at the lower ends of the four fixed arms 23. Assembly joints are opened on one side of each liquid outlet pipe 24 in the liquid chamber 21.

Clamping plates 37 are provided on the upper two sides of the cantilever plate 36, and the clamping plates 37 and the abutment plates 38 clamp the middle of the wear-resistant rubber tube 25 and seal it.

Two positioning holes 35 are symmetrically opened on the upper end of the positioning platform 32 and the fixing screw The lower end of rod 34 is inserted into the positioning hole 35 on one side. When high-pressure gas is introduced into the two atomizing tubes 18 through the air supply pipe 19, the high-pressure gas is ejected at high speed from the end of the atomizing tube 18. Since the liquid outlet pipe 24 is close to the jet position of the atomizing tube 18, the pressure at the end of the liquid outlet pipe 24 decreases. The liquid in the storage tank 11 enters the transfer cylinder 20 through the liquid delivery hose 22, and then is ejected from the two liquid outlet pipes 24. Under the action of high-pressure gas, it quickly forms a mist. Then, under the shielding effect of the flow guide shroud 15, the condensed large water droplets fall into the storage tank 11. The lighter mist is driven by the airflow and enters the diversion chamber 26. Then, under the action of several diffuser ports 30, it is blown to all sides. When the diffuser plate 4 is above the external environment, it can efficiently disinfect the space above.No operator is required to hold the disinfection equipment at a height; When two of the liquid outlet pipes 24 are in use, the wear-resistant rubber tubes 25 of the other two liquid outlet pipes 24 are clamped and sealed by the clamping plate 37 and the abutment plate 38, so as to make full use of the liquid. When two of the liquid outlet pipes 24 become blocked, the diffuser plate 4 is lowered, the control arm 33 is rotated so that the fixing screw 34 is inserted into another positioning hole 35, and the position of the atomizing tube 18 is switched by 90°. The two liquid outlet pipes 24 are switched for use. After the switching is completed, the lifting and lowering are continued. The lengths of the liquid delivery hose 22 and the air delivery hose 19 can be customized according to requirements, and will not affect the normal connection settings when the lifting movable plate 3 is raised to its maximum extent. In addition, the condensed medicine in the diversion chamber 26 can also be returned to the storage tank 11 through the guide mechanism to make full use of the medicine. Example 4

[0022] Based on Embodiment 3, the atomized flue gas is guided and diffused. The diffusion component is symmetrically provided with several diffusion ports 30. Each diffusion port 30 has a sealing ball head 29 on one side, and the sealing ball heads 29 are movably inserted into the outer periphery of the diffusion disk 4. The diffusion disk 4 has several damping sealing ball grooves 28 arranged in a ring array. One side of the damping sealing ball grooves 28 is connected to the diversion cavity 26. One side of the damping sealing ball grooves 28 has a swing groove that penetrates the outer periphery of the diffusion disk 4. The sealing ball heads 29 on one side of the several diffusion ports 30 are movably inserted into the several damping sealing ball grooves 28. The diffusion ports 30 movably penetrate the swing grooves. A wide-angle groove 31 is provided on one side of the sealing ball head 29. The wide-angle groove 31 is connected to the diffusion port 30, and two adjacent diffusion ports 30 are respectively set upward and downward. When disinfecting in the external environment, the upper atomization area is increased.
