[0021] The ventilation mechanism 6 includes a dust box 601, a dust box 602, a hose 603, a dust suction motor 604, an air inlet pipe 605, a dustproof sheet 606, a fixed column 607 and a filter element 608.

The lower surface of the dust collection motor 604 is electrically connected to a thermal transmitter 609, and one side surface of the thermal transmitter 609 is fixedly connected to a thermal column 610. Through the setting of the ventilation mechanism 6, when in use, when the detection equipment needs to work, the sample material is placed in the detection box 3, and then the box door 4 is closed. The detection box 3 analyzes the sample inside. During operation, the temperature inside the detection box 3 rises, and the thermal column 610 picks up the temperature rise. Then the thermal transmitter 609 receives the information of the temperature rise of the thermal column 610, and the thermal transmitter 609 starts The automatic dust suction motor 604 is turned on and runs, sucking air from the air inlet pipe 605. There is also a dustproof sheet 606 at the air inlet pipe 605 to block some dust from entering the ventilation mechanism 6. The air enters the dust suction motor 604, and the dust suction motor 604 separates most of the dust from the air. Most of the dust particles fall into the dust collection box 601 through the hose 603. The dust collection box 601 is slidably connected to the dust collection box 602, and the dust particles inside the dust collection box 601 can be cleaned at any time. Then the remaining air enters the filter element 608 through the fixed column 607. The activated carbon inside the filter element 608 further purifies the air and removes odors and harmful gases.

[0022] Furthermore, the support columns 2 are symmetrically distributed around the central axis of the base 1, and the inner wall size of the air inlet pipe 605 matches the outer wall size of the dustproof sheet 606. Through the arrangement of the base 1, the support columns 2, the air inlet pipe 605 and the dustproof sheet 606, when in use, the base 1 provides a stable basic support for the entire device, ensuring that the equipment will not easily shake or tip over during operation. The support columns 2 are symmetrically distributed around the central axis of the base 1. This symmetrical design makes the equipment more evenly stressed in all directions, further enhancing the stability of the overall structure. The inner wall size of the air inlet pipe 605 matches the outer wall size of the dustproof sheet 606, ensuring that the dustproof sheet 606 can be tightly installed in the air inlet pipe 605, preventing dust and impurities from entering the interior of the equipment through the gaps during the air intake process.

[0023] Furthermore, the fixed column 607 is symmetrically arranged with respect to the central axis of the dust suction motor 604, and the filter element 608 is symmetrically arranged with respect to the central axis of the fixed column 607. Through the arrangement of the fixed column 607, the dust suction motor 604 and the filter element 608, when in use, the fixed column 607 is symmetrically arranged with respect to the central axis of the dust suction motor 604, providing stable support and fixation for the dust suction motor 604. This symmetrical layout makes the force exerted on the motor during operation more evenly distributed, reducing the risk of equipment shaking and damage caused by vibration or unbalanced force. The filter element 608 is symmetrically arranged with respect to the central axis of the fixed column 607, so that the air can be more evenly distributed when passing through the filter element 608. This symmetrical layout helps to improve the filtering efficiency of the filter element 608, ensuring that dust and impurities in the air can be fully intercepted and adsorbed.

[0024] Furthermore, the inner wall size of the dust box 601 is consistent with the outer wall size of the dust box 602, and the hose 603 is evenly distributed on the outer wall of the dust box 601. Through the arrangement of the dust box 601, the dust box 602 and the hose 603, when in use, the hose 603 is evenly distributed on the outer wall of the dust box 601, so that air and dust can enter the dust box 601 evenly. This uniform air intake method can improve the dust collection efficiency and ensure that dust from all parts can be effectively sucked into the dust box 601. The inner wall size of the dust box 601 is consistent with the outer wall size of the dust box 602, and it can be easily taken out of the dust box 601 for cleaning.

[0025] Furthermore, the fixed column 607 is threadedly connected to the filter element 608 through the dust suction motor 604, and the dust collection box 602 forms a telescopic structure with the dust collection box 601 through the detection box 3. Through the arrangement of the detection box 3, the dust collection box 602, the dust collection box 601, the fixed column 607, the dust suction motor 604 and the filter element 608, when in use, the fixed column 607 is threadedly connected to the filter element 608 through the dust suction motor 604. This connection method is relatively firm and can ensure that the filter element 608 will not loosen or fall off during the operation of the dust suction motor 604, which helps to maintain the overall stability of the equipment and ensure the normal performance of the dust collection and filtering functions. The dust collection box 602 forms a telescopic structure with the dust collection box 601 through the detection box 3. This design can adjust the size of the dust collection space according to actual needs. When a large amount of dust needs to be collected, the dust collection box 602 can be extended to increase the dust collection capacity. When not in use or when space needs to be saved, the dust collection box 602 can be retracted for easy storage and transportation.

[0026] Furthermore, the first dustproof net 7 is symmetrically arranged with respect to the central axis of the detection box 3, and the fixed block 9 forms a rotating structure with the fixed shaft 10 through the detection box 3. Through the arrangement of the detection box 3, the first dustproof net 7, the fixed block 9 and the fixed shaft 10, when in use, the first dustproof net 7 is symmetrically arranged with respect to the central axis of the detection box 3, which can more comprehensively block dust from entering the detection box 3. The symmetrical layout ensures an effective dustproof barrier in all directions, reduces the damage of dust to the precision components inside the detection equipment, and improves the accuracy and reliability of the detection.

[0027] Furthermore, the baffle 11 is symmetrically arranged with respect to the central axis of the air outlet baffle 13, and the baffle 11 is distributed in parallel with the detection box 3. Through the arrangement of the detection box 3, the baffle 11 and the air outlet baffle 13, when in use, the baffle 11 is symmetrically arranged with respect to the central axis of the air outlet baffle 13, which helps to guide the flow direction of air in the detection box 3. This symmetrical layout can make the air pass through the detection area more evenly, thereby improving the accuracy and reliability of the detection. The baffle 11 is distributed in parallel with the detection box 3, which can reduce the resistance to air flow and ensure that the air flows smoothly in and out of the detection box 3, which helps to improve the ventilation performance of the equipment and prevent overheating and dust accumulation.

[0028] Working principle: When the detection equipment needs to work, the sample material is placed in the detection box 3, and then the box door 4 is closed. The detection box 3 analyzes the sample inside. During operation, the temperature inside the detection box 3 rises, and the thermal column 610 picks up the temperature rise. Then the thermal transmitter 609 receives the information of the temperature increase of the thermal column 610, and the thermal transmitter 609 starts the dust suction motor 604 to start running, and sucks air from the air inlet pipe 605. There is also a dustproof sheet 606 at the mouth of the air inlet pipe 605, which blocks some dust from entering the ventilation mechanism 6. The air enters the dust suction motor 604, and the dust suction motor 604 separates most of the dust from the air. Most of the dust particles fall into the dust box 601 through the hose 603. The dust box 601 is slidably connected to the dust box 602, and the dust particles inside the dust box 601 can be cleaned at any time. Then the remaining air enters the filter element 608 through the fixed column 607. The filter element 608 The activated carbon inside further purifies the air, removes odor and harmful gases, and finally the air enters the detection box 3 through the first dustproof net 7. The rising gas inside the detection box 3 will be discharged from the detection box 3 through the second dustproof net 8 and the baffle 11. The fixed block 9 and the fixed shaft 10 are rotatably connected. The air can only be discharged from the baffle 11 but cannot enter. Finally, the gas in the detection box 3 is discharged through the air outlet baffle 13. A rubber ring 12 is fixedly connected to one side of the baffle 11. When the detection box 3 is operating, the rubber ring 12 fits with the outer surface of the detection box 3 to prevent air from flowing back into the detection box 3. In this way, the ventilation mechanism 6 can discharge these interfering gases in time to ensure that only the signal of the target substance is in the detection environment, thereby improving the accuracy of the detection. The model of the dust suction motor 604 is RS-380PA-4239, thus completing a magnetic adsorption material and its use in benzoylurea insecticide detection equipment.
