Description

Technical Field

[0001] This utility model relates to the technical field of insecticidal and disinfectant fumigation machines, specifically to an insecticidal and disinfectant fumigation device. Background Technology

[0002] In the daily management of warehouses, libraries, and other similar facilities, pest control and disinfection are crucial for ensuring the safety of goods and preventing the growth of pests and pathogens. Traditional pest control and disinfection methods have many drawbacks. Early methods often involved manual spraying of chemical agents, requiring workers to walk around the premises with handheld sprayers. This method was not only labor-intensive and inefficient, but also made it difficult to ensure even application of the agent, easily resulting in areas with too much or too little agent. Too much agent could damage stored goods, while too little would fail to effectively kill pests and pathogens.

[0003] Later, some fixed fumigation devices emerged, but these devices were mostly simple in structure and single in function. They typically just heated and atomized the pesticide and discharged it directly, without precise control over the atomization temperature. This resulted in unstable atomization effects, affecting the insecticidal and disinfection efficacy. Furthermore, the fixed direction of the smoke spray from these devices made it difficult to cover every corner of the area. In larger, more complex spaces, they failed to achieve comprehensive and effective fumigation, leaving blind spots for pest and disease growth. Utility Model Content

[0029] Example 3: An insecticidal and disinfectant fumigation device has a maintenance door 3 on the right side of the main body 1 and an air inlet 6 on the left side. Inside the main body 1, a blower 5 is mounted on a partition 8, and a battery 4 and a medicine tank 11 are located at the bottom. The medicine tank 11 has a liquid inlet, contains aluminum phosphide disinfectant solvent, and a liquid level sensor. An air supply pipe 7 connects to the blower 5 and extends to the front. A notch on the lower surface allows a vertical pipe 12 to be inserted. The vertical pipe 12 is connected to a wide-face mask 13. The wide-face mask 13 contains an electric heating wire 14 and a temperature sensor. The electric heating wire 14 is connected to the battery 4. Inside the main body 1, there is a circuit board 9 for controlling the temperature of the electric heating wire 14. A water pump 10 is located at the lower front of the inner cavity. It draws liquid from the medicine tank 11 through a liquid extraction pipe 16 and sprays it into the wide-face mask 13 through an atomizing nozzle 15. The programmable servo motor 17 on the front side wall of the main body 1 is connected to the swing arm 19 via the rotating shaft 18. The front end of the swing arm 19 is connected to the hoop 22 via the shaft pin 20 and the L-shaped seat 21. The hoop 22 is fitted onto the bellows 2, which is connected to the front end of the air supply pipe 7. After programming, the output shaft of the programmable servo motor 17 rotates 180° left and right, with an interval of 7 seconds. In use, the disinfectant solvent is atomized and heated and then sent out by the blower 5. The programmable servo motor 17 drives the bellows 2 to swing left and right, so that the disinfectant smoke covers every corner of the warehouse, library and other scenes.

[0030] Based on the above-described preferred technical solution, the workflow of the technical solution is explained as follows: When the insecticidal and disinfectant fumigation device is working, aluminum phosphide disinfectant solvent is first added into the medicine tank 11 through the liquid inlet on the right end face of the medicine tank 11. The liquid level sensor in the medicine tank 11 can monitor the solvent level in real time. The air inlet window 6 in the air inlet on the left side wall of the machine body 1 is used for air intake to ensure air circulation in the device. After the device is turned on, the water pump 10 starts, and its suction port draws aluminum phosphide disinfectant solvent from the bottom of the medicine tank 11 through the suction pipe 16 connected to the pipe connector. Then, the solvent is sprayed into the inner cavity of the mask 13 through the atomizing nozzle 15 connected to the infusion end. At the same time, the battery 4 supplies power to the electric heating wire 14 in the inner cavity of the mask 13. The electric heating wire 14 heats the aluminum phosphide disinfectant solvent entering the mask 13, causing it to be further atomized into disinfectant smoke. The circuit board 9 fixed on the front side wall of the inner cavity of the body 1 can control the temperature of the electric heating wire 14. The temperature sensor in the inner cavity of the mask 13 can provide real-time temperature feedback so that the circuit board 9 can accurately regulate the temperature. While the disinfectant solvent is atomized, the blower 5 fixed above the inner cavity of the machine body 1 starts to operate, drawing in outside air through the air inlet 6. After being pressurized by the blower 5, the air is delivered through the air delivery pipe 7 connected to the gas delivery end. A fixed vertical pipe 12 passes through the lower surface of the air delivery pipe 7 to guide part of the air into the wide-face mask 13. After mixing with the atomized disinfectant smoke, the air is discharged together from the lower port of the wide-face mask 13. The corrugated pipe 2 fixed at the front end of the air delivery pipe 7 can exhaust the mixed disinfectant smoke outside the device.

[0031] At this time, the programmable servo motor 17 fixed on the front side wall of the machine body 1 starts. Its output end, through a coupling-connected shaft 18, drives the swing arm 19 fixed at the top of the shaft 18 to reciprocate left and right. After programming, the output shaft of the programmable servo motor 17 rotates 180° left and right, with an interval of 5-7 seconds. The hoop 22 connected to the front end of the swing arm 19 is fitted onto the outer ring of the front section of the bellows 2. When the swing arm 19 swings left and right, it drives the hoop 22 to swing, thereby causing the bellows 2 to swing accordingly, changing the spray direction of the disinfection smoke, allowing the disinfection smoke to cover a wider area, and achieving comprehensive fumigation and disinfection of warehouses, libraries, and other scenarios. After the device has been used for a period of time, the interior of the device can be inspected and maintained through the maintenance door 3, which is connected by a hinge at the maintenance port on the right side wall of the machine body 1. The handle on the outside of the maintenance door 3 makes it easy to open, and the lock on the inside ensures the stability of the maintenance door 3 when closed.
