[0042] A plurality of horn-shaped communicating tubes 43 which are evenly spaced and distributed above the outer wall of the base 11 are connected, and one end of the outer wall of each communicating tube 43 is detachably connected to a diffusion component 44 which is connected thereto, and the diffusion component 44 comprises a positioning tube 45 with openings at both ends, a plurality of air holes 46 which are opened on the left and right sides of the upper end of the outer wall of the positioning tube 45 and arranged along its length, and a shielding component 47 which is arranged along the upper end of the outer wall of the positioning tube 45 and is used to block the air holes 46, and a gap is left between the shielding component 47 and the upper end of the outer wall of the positioning tube 45, and the shielding component 47 comprises an arc-shaped blocking piece 48, and a plurality of support rods 49 which are evenly spaced and arranged on the left and right sides of the lower end of the blocking piece 48, and the lower end of the inner wall of the box body 34 is provided with a plurality of water absorbing rods 5 which extend out of its outer wall and correspond one-to-one with the diffusion components 44 and extend into the corresponding positioning tubes 45, and the air pump 19, the two-position three-way reversing valve 23, the spraying component 36 and the battery 27 are all electrically connected to the control panel 28.

[0043] Method of use: When using, first dig a pit where the base 11 can be placed at the location where pests and diseases need to be eliminated, connect the diffusion component 44 with the connecting pipe 43 and keep the shielding component 47 facing upward, then place the water absorbing rod 5 in the positioning tube 45 corresponding to the diffusion component 44, then place the base 11 in the pit and bury the positioning tube 45 in the soil, and the shielding component 47 will separate the soil from the air vent 46, and at the same time, the upper end of the positioning tube 45 is kept hollow through the baffle 48 on the support rod 49, and then the baffle 52 is placed on the positioning ring 51 to cover the pit. And cover with soil to keep the pit hollow, then remove the plug 32, add insecticide into the liquid chamber 17 separated by the spacer 16 of the liquid storage cylinder 15 through the corresponding liquid inlet pipe 31, add sex attractant into the liquid storage chamber 18, then cover the plug 32, press the control button 3 on the handle 29, and the battery 27 provides power to control the air pump 19 and the spray assembly 36 to work through the control panel 28. The heat generated by the air pump 19 can be discharged through the heat dissipation hole 2, and the partition net 21 can prevent insects from entering the fixed pipe 1 through the heat dissipation hole 2 and the air inlet 14.

[0044] The gas generated by the air pump 19 is divided into two air paths through the first three-way pipe 22. One air path is divided into two sub-air paths again when passing through the position of the two-position three-way reversing valve 23. One sub-air path is transported to the medicine liquid chamber 17 through the first air guide pipe 24 to be appropriately pressurized, and the other sub-air path is transported to the liquid storage chamber 18 through the second air guide pipe 25 to be appropriately pressurized. The other air path is transported to the lower end of the second three-way pipe 37 of the spray assembly 36 through the third air guide pipe 26. The sex attractant in the pressurized liquid storage chamber 18 will first flow into the box body 34 on the connecting frame through the third liquid guide pipe 42 and soak the sponge pad 35. At the same time, the sex attractant will soak the water absorption rod 5 and flow into the positioning tube 45 along the water absorption rod 5, and the smell of the sex attractant in the positioning tube 45 will diffuse into the soil layer through the air vent 46.

[0045] Then the silent fan 13 starts to work, and the outside air enters the fixed tube 1 through the air inlet 14 to blow away the smell of the sex attractant and flow along the positioning tube 45. At the same time, the corresponding solenoid valve 38 on the second liquid guide tube 41 opens to transport the sex attractant to the atomizing nozzle 39 of the liquid spraying assembly 36. At this time, one end of the two-position three-way reversing valve 23 is closed and the other end is opened. The air pump 19 pressurizes the liquid storage chamber 18 to atomize and spray the sex attractant from the atomizing nozzle 39. After a period of time, the air pump 19 stops working, and the silent fan 13 diffuses the sprayed sex attractant into the soil layer through the slot 12 and the diffusion assembly 44 to frequently lure the target pests and allow the pests to enter the space of the base 11.

[0046] After a period of time, the air pump 19 continues to work. At this time, one end of the two-position three-way reversing valve 23 is opened and the other end is closed, so that the air pressure in the liquid chamber 17 increases. At the same time, the solenoid valve 38 corresponding to the first liquid guide pipe 4 opens and transports the insecticide liquid to the atomizing nozzle 39 in the second three-way pipe 37 and cooperates with the third air guide pipe 26 to spray it out to complete the disinfecting of target pests. In the process of atomizing the sex attractant and the insecticide liquid, the gas in the third air guide pipe 26 can accelerate the flow rate of the sex attractant and the insecticide liquid and accelerate the air flow in the base 11. When the sex attractant and the insecticide liquid are sprayed through the spray assembly 36, the control panel 28 controls it to work intermittently, which can reduce the waste of liquid and improve the killing effect.
