[0026] Indoor pest protection device for tobacco factories, such as Figure 1As shown in the figure, it includes a compensable composite medicine tube 1, and the compensable composite medicine tube includes a breathable outer tube 2 and a porous inner tube 4; a drug adsorption layer 5 is arranged between the breathable outer tube 2 and the porous inner tube 4; the drug adsorption layer 5 can be a corrosion-resistant adsorption material such as a fiber product, a sponge product, a polypropylene adsorption material, an activated carbon fiber cloth, etc. A support arm 7 is arranged between the breathable outer tube 2 and the drug adsorption layer 5, so as to form a negative pressure cavity 7-1. The function of the negative pressure cavity 7-1 is: when in use, a negative pressure cavity is formed to promote the better flow of the aerosol mixed hot body in the porous inner tube 4; at the same time, it promotes the cold air outside the breathable outer tube to contact the drug adsorption layer, and improves the condensation effect of the aerosol mixed hot body at the drug adsorption layer. The front end of the porous inner tube 4 is open to facilitate the inflow of atomized liquid medicine, and its end is closed to promote better extraction of negative pressure during operation, which is beneficial to the flow of the atomized liquid medicine in the porous inner tube 4. A number of medicine outlet holes 6 are arranged on the side wall of the porous inner tube 4. When the negative pressure cavity 7-1 forms a negative pressure, it is beneficial to the longer-distance flow of the atomized medicine in the porous inner tube 4, ensuring that the drug adsorption layer 5 on the entire compensable composite medicine tube can adsorb the medicine. During preparation, the main material of the compensable composite medicine tube can be a bendable material such as copper, flexible silica gel, bendable plastic, etc. If a hard material such as hard plastic is selected, a turning joint can be provided to achieve the coverage layout of relevant indoor or equipment-related areas.

The functions of arranging the breathing holes 3 are: (1) improving the negative pressure effect of the negative pressure cavity 7-1; (2) facilitating the intrusion of the external normal-temperature air of the breathable outer tube 2. If a constant-temperature heating module is turned on in the ultrasonic atomizing medicine dispenser, it can improve the condensation effect of the aerosol mixed hot body on the drug adsorption layer 5; (3) after the medicine application operation is completed, it promotes the uniform emission of the medicine on the daily drug adsorption layer 5 from the breathing holes 3, playing a role in insect repellent and protection, preventing pests from nesting. If the liquid medicine used contains components such as fumigant insecticides, such as cockroach medicine, etc., it can kill pests by relying on the volatility of the fumigant insecticide, and if it contains insect repellent essential oils, etc., it can achieve a persistent insect repellent effect. However, in actual operation, it is not limited to the above drug components, and the above only listed drugs should not be understood as a limitation to the protection scope of the present invention.

[0028] Preferably, it also includes a breathable breathing layer 2-1, which is coated on the outer wall of the breathable outer tube 2; the breathable breathing layer 2-1 is made of an insulating breathable material or a flame-retardant breathable material, and its function is: if the breathable outer tube 2 is made of metal material, it has an insulating effect; if the breathable outer tube 2 is made of plastic material, it has a flame-retardant effect, and the use of a breathable material can not hinder the breathing function of the breathing hole 3 of the breathable outer tube 2 and slow down the emission of drugs.

[0029] like Figure 4 As shown, if it is set inside the housing of the device 35 (the bottom surface of the inner cavity of the device), the compensable composite drug tube 1 of the utility model is arranged according to Figure 4 After the entire bottom surface is arranged, a hole can be drilled on each side of the device shell, and then the front end 1-1 of the compensating compound medicine tube 1 can pass through the outside of the device shell, and its rear end 1-2 also passes through the outside of the device shell. The advantage of this arrangement is that when drug replenishment operation is required, there is no need to disassemble the device shell, and the front end 1-1 can be directly connected to the medicine tube, and the rear end 1-2 can be connected to the negative pressure device to complete the drug replenishment operation, which is easy to operate.

[0030] Preferably, Figure 2 As shown, it also includes an ultrasonic atomizer drug delivery device, which includes a medicine liquid tank 18 and an air inlet pipe 14. The upper part 17 of the medicine liquid tank 18 is provided with a cone. The medicine liquid tank 18 is used to contain medicine liquid 8, and an ultrasonic atomization module 19 is provided at the bottom; the upper part of the medicine liquid tank 18 is also provided with a dosing port 9 and a cover 10; the air inlet pipe 14 is arranged above the medicine liquid tank 18 and is arranged vertically; the inner cavity of the air inlet pipe 14 is provided with a mist outlet pipe 12 along its axial direction; the lower part 16 of the mist outlet pipe 12 is arranged in a trumpet structure; the side wall of the mist outlet pipe 12 is provided with a plurality of air inlet holes 15; the side wall of the air inlet pipe is provided with an air inlet 13; the upper end of the mist outlet pipe is detachably connected to the front end of the porous inner tube 4.

To improve the sealing performance, in this embodiment, a sealing ring 26 is correspondingly arranged.

[0034] The air inlet chamber 27 is provided with an air inlet 28; an activated carbon layer 31 is arranged on the air cylinder 25. In this embodiment, the activated carbon layer 31 can use a replaceable activated carbon filter cotton ring, which has the advantages of good filtering effect, low cost, convenient disassembly and assembly operation, etc., and thus there is no need to replace the whole air cylinder 25. Preferably, a plurality of air extraction holes 32 are arranged on the side wall of the air cylinder 25, and the activated carbon layer 31 covers the air extraction holes.
