[0001] This utility model relates to the field of chemical fumigation testing, and in particular to an insect chemical fumigation testing device. Background Technology
[0002] Chemical agents are commonly used in agriculture, warehousing, and disease prevention to disinfect harmful insects. To determine the effectiveness of these chemical agents, it is necessary to use testing equipment to examine the efficacy of the agents on several insect samples. For testing volatile chemical agents, fumigation is often used, thus requiring a corresponding fumigation testing device to assist staff in achieving the testing objectives.
[0003] For example, patent document CN218512414U discloses a fumigation efficacy testing device, relating to the field of insecticide testing tools. It includes an inner tube and an outer tube, with the inner tube located inside the outer tube and detachably connected. The inner tube comprises a body and a cap, which are also detachably connected. A screen is located at the bottom of the body, and the interior of the body is divided into several isolation zones by partitions. The lower end of each partition is connected to the screen. When the cap is closed, the upper end of each partition contacts the cap. The outer tube is used to hold the insecticide. This device can be used for fumigation efficacy testing. During the test, several test insects are placed in the isolation zones, ensuring that each isolation zone contains only one test insect to avoid mutual interference between insects and facilitate observation of the test results. In the prior art, the airflow rate carrying the chemical agent should vary depending on the type of insect entering during fumigation testing to facilitate the experiment. Summary of the Invention
[0004] The purpose of this invention is to provide an insect fumigation test device to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] An insect fumigation testing device includes a main body, which includes a fumigation chamber. A connecting ring is fixedly connected to the bottom of the fumigation chamber, and an insecticide chamber is fixedly connected to the bottom of the connecting ring. An insect storage mechanism is provided inside the fumigation chamber. A flow control mechanism is provided on the connecting ring.

Two symmetrically arranged arc-shaped toothed plates are fixedly connected to the notch of the connecting ring. Several evenly spaced notches are opened on the edges of the arc-shaped toothed plates. A fixed prism is fixedly connected to the outside of the rotating ring. A limit slider is slidably connected to the fixed prism. A spring is fixedly connected between one side of the limit slider and the fixed prism. One end of the limit slider can cooperate with the notch on the arc-shaped toothed plate for limitation. An airflow disturbance component is provided on the upper cover.
[0007] Preferably, the top of the fumigation chamber is movably connected to a top cover, and the bottom of the agent chamber is slidably connected to a drawer, with several absorbent papers placed inside the drawer, the absorbent papers absorbing the agent.
[0008] Preferably, the fumigation chamber has observation windows on both sides covered with transparent plastic, and two doors are slidably connected to the fumigation chamber, which can cover the observation windows on the fumigation chamber.
[0009] Preferably, the insect storage mechanism includes symmetrically arranged support columns fixedly connected to the inner wall of the fumigation chamber, with crossbeams movably connected to the support columns, connecting plates fixedly connected to the bottom of the crossbeams, the top of the crossbeams able to contact the bottom of the top cover, and a wire mesh box bolted to the bottom of the connecting plate, the wire mesh box being used to place insects.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] like Figures 1-9As shown, an insect fumigation test device includes a main body, which includes a fumigation chamber 101. A connecting ring 106 is welded to the bottom of the fumigation chamber 101, and an insecticide chamber 102 is welded to the bottom of the connecting ring 106. An insect storage mechanism is provided inside the fumigation chamber 101. A flow control mechanism is provided on the connecting ring 106, which includes a rotating ring 303 rotatably connected to the connecting ring 106. A lower cover plate 302 is fixedly connected inside the rotating ring 303. An upper cover plate 301 is fixedly connected to the bottom of the fumigation chamber 101. The upper cover plate 301 and the lower cover plate 302 have several fan-shaped notches that can block and close each other. The upper cover plate 301 and the lower cover plate 302 are tightly attached vertically. A notch is provided on the front side of the connecting ring 106. Two symmetrically arranged arc-shaped toothed plates 305 are fixedly connected to the notch of the connecting ring 106. Several evenly arranged notches are opened on the edges of the arc-shaped toothed plates 305. A fixed prism 304 is fixedly connected to the outer side of the 03. A limiting slider 306 is slidably connected to the fixed prism 304. A spring 307 is fixedly connected between one side of the limiting slider 306 and the fixed prism 304. One end of the limiting slider 306 can cooperate with the notch on the arc-shaped toothed plate 305 for limiting. An airflow disturbance component is provided on the upper cover 301. When it is necessary to control the flow rate of the medicine, the operator moves the limiting slider 306 outward. At this time, the spring 307 is compressed, and the limiting slider 306 cancels the cooperation with the notch on the arc-shaped toothed plate 305. In this way, the operator can drive the rotating ring 303 to rotate through the fixed prism 304. The rotating ring 303 drives the lower cover 302 to rotate. The relative displacement between the lower cover 302 and the upper cover 301 creates a gap that allows gas to flow, thereby realizing the control of the flow rate of the medicine. The evenly distributed notches on the arc-shaped toothed plate 305 can quantitatively control the rotation angle of the lower cover 302.
[0030] The top of the fumigation chamber 101 is movably connected to a top cover 103, and the bottom of the agent chamber 102 is slidably connected to a drawer 105. Several absorbent papers 107 are placed inside the drawer 105, and the absorbent papers 107 absorb the agent. Observation windows are opened on both sides of the fumigation chamber 101 and covered with transparent plastic. Two windows 104 are slidably connected to the fumigation chamber 101, and the windows 104 can cover the observation windows on the fumigation chamber 101. Before conducting the fumigation test, the staff uses the absorbent papers 107 to absorb the agent, and then places the absorbent papers 107 in the drawer 105. Then, the insect storage mechanism is placed in the fumigation chamber 101, and the top cover 103 is closed to form a sealed space. Then, the gap between the upper cover 301 and the lower cover 302 is opened to allow the air carrying the agent to flow into the fumigation chamber 101. Then, the airflow disturbance component is activated to enhance the circulation of air between the fumigation chamber 101 and the agent chamber 102.
[0031] The insect storage mechanism includes symmetrically arranged support columns 203 welded to the inner wall of the fumigation chamber 101. A crossbeam 201 is movably connected to the support column 203. A connecting piece 204 is fixedly connected to the bottom of the crossbeam 201. The top of the crossbeam 201 can contact the bottom of the top cover 103. A net box 202 is bolted to the bottom of the connecting piece 204. The outer side of the net box 202 is made of fine mesh. The net box 202 is used to hold insects. Grooves are provided on both sides of the crossbeam 201. The support column 203 contacts and fits with the grooves on the crossbeam 201. The bottom of the crossbeam 201 is set in a Z-shape. The Z-shape can ensure the connection strength and prevent the net box 202 from tilting. The staff puts the insects and the feed for the insects into the net box 202, and then puts the net box 202 into the fumigation chamber 101. During this process, the crossbeam 201 and the support column 203 are positioned and fitted. After the top cover 103 is in place, it can press and fix the position of the crossbeam 201, so the net box 202 will not move easily in the fumigation chamber 101.
[0032] The airflow disturbance component includes a motor 308 fixedly connected to the fumigation chamber 102. A drive shaft 309 is fixedly connected to the output end of the motor 308. The drive shaft 309 is rotatably connected to the fumigation chamber 102. A first bevel gear 310 is fixedly connected to the other end of the drive shaft 309. A second bevel gear 311 is rotatably connected to the upper cover 301. The second bevel gear 311 meshes with the first bevel gear 310. The second bevel gear 311 passes through the lower cover 302. A baffle fan 312 is fixedly connected to the upper end of the second bevel gear 311. The motor 308 drives the drive shaft 309 to rotate. The drive shaft 309 drives the first bevel gear 310 to rotate. The first bevel gear 310 drives the second bevel gear 311 to rotate. The second bevel gear 311 drives the baffle fan 312 to rotate. In this way, the baffle fan 312 can disturb the air in the fumigation chamber 101 and the fumigation chamber 102 and increase the air circulation efficiency.
[0033] Working principle: Workers use absorbent paper 107 to absorb the pesticide, then place the absorbent paper 107 in drawer 105. Insects and their feed are then placed into net cage 202, which is then placed into fumigation chamber 101. During this process, the crossbeam 201 and support column 203 are positioned and fitted together, and then the top cover 103 is closed to form a sealed space. Once in place, the top cover 103 presses down and fixes the crossbeam 201, preventing the net cage 202 from easily moving within the fumigation chamber 101. Then, the worker moves the limiting slider 306 outwards. At this time, the spring 307 is compressed, and the limiting slider 306 no longer engages with the notch on the arc-shaped toothed plate 305. Thus, the worker can rotate the rotating ring 303 by fixing the prism 304. The lower baffle 302 rotates, and the relative displacement between the lower baffle 302 and the upper baffle 301 creates a gap that allows gas to flow, thereby controlling the efficiency of the agent flow. The evenly distributed notches on the arc-shaped toothed plate 305 can quantitatively control the rotation angle of the lower baffle 302, so that the air carrying the agent can flow into the fumigation chamber 101. Then, the airflow disturbance component is activated, and the motor 308 drives the transmission shaft 309 to rotate. The transmission shaft 309 drives the first bevel gear 310 to rotate, the first bevel gear 310 drives the second bevel gear 311 to rotate, and the second bevel gear 311 drives the baffle fan 312 to rotate. In this way, the baffle fan 312 can disturb the air in the fumigation chamber 101 and the agent chamber 102, enhancing the air circulation between the fumigation chamber 101 and the agent chamber 102.
