AI Technical Summary

Technical Problem

Existing insect traps lack an active airflow circulation system, resulting in limited odor diffusion range and susceptibility to interference from external airflow, leading to confusion in the target insect's location and low trapping efficiency.

Method used

An airflow-oriented insect trapping device was designed. By setting an exhaust chamber and a guide grid on the sleeve, an airflow channel is established using an air extraction mechanism to form a horizontal spiral airflow, which enhances the directional diffusion of odors and creates a negative pressure suction effect at the inlet. The volatilization efficiency of the insect bait is controlled by a temperature sensor and an electric heating element.

Benefits of technology

It increases the trapping range, improves trapping efficiency, prolongs the time insects stay near the trapping device, and ensures the stability of the odor concentration gradient, thereby improving the insect trapping effect.

Abstract

The utility model relates to the technical field of insect trapping equipment, in particular to an airflow guide type insect trapping device which comprises a sleeve, an exhaust cavity, a bait pipe and an air exhaust mechanism, the sleeve comprises an inlet and an outlet, the inlet is formed in the periphery close to the upper end of the sleeve, and the outlet is formed in the lower end of the sleeve and connected with a collecting container; the exhaust cavity is formed in the upper end of the sleeve and provided with a guide grid in the circumferential direction. The bait pipe is arranged in the sleeve, the upper end of the bait pipe is communicated with the exhaust cavity, the lower end of the bait pipe is provided with a containing part used for containing insect trapping bait, and a capturing cavity is formed between the inner wall of the sleeve and the outer wall of the bait pipe. The air exhaust mechanism is arranged in the bait pipe and used for establishing an air flow channel from the capturing cavity to the air exhaust cavity through the bait pipe, so that the smell of the insect trapping bait in the containing part is diffused outwards in an accelerated mode through the guide grid, meanwhile, the negative pressure suction effect is formed at the inlet, the directional diffusion capacity of the smell can be enhanced, and therefore the trapping range is enlarged; the trapping efficiency is improved.
