Description

Air suction type insect killing lamp

Technical Field

The utility model relates to an insecticidal lamp technical field especially relates to a formula insecticidal lamp is inhaled to wind.

Background

The air-suction type insect killing lamp utilizes phototaxis of pests, takes a specific spectrum sensitive to the pests as an induction light source to induce the pests to fly, a fan stirs surrounding air at a high speed to form vortex, the pests which are used to fly along with air flow come with the wind, once the flying pests are sucked into the insect killing lamp, the flying pests are absolutely difficult to escape from the strong vortex formed by the fan, and the flying pests are sucked to the bottom of a catcher by the fan until the flying pests are dried in the air and died. The insect killing lamp can be used in the field to effectively kill insects, reduce the using amount of pesticides and play a positive role in ecological protection and green agriculture.

The traditional air suction type insect killing lamp adopts an axial flow type air duct, in order to ensure the air suction effect, the air inlet duct is extremely short, the light source can only be close to the inlet position of the air duct as much as possible, about 30-50% of light rays are blocked by the air duct, and the induction effect is reduced; the air pressure distribution of the inlet is uneven, the flow field of the air channel is easily damaged by natural cross wind, and the outlet of the fan is directly connected with the cloth bag or the net cage, so that the exhaust loss of the fan is large, and the air suction effect of the inlet is further reduced; under the influence of the rotation of the fan, a strong circumferential vortex is formed in the air inlet duct, and the sucked winged insects can escape reversely by virtue of the centrifugal force generated by the vortex; once the winged insect contacts with the fan blade rotating rapidly, a large tangential acceleration is obtained, the winged insect is reversely thrown out of the air channel, and the probability of escaping is high.

The screen plate 5 is repeatedly detachable, and the minimum maintenance requirement for cleaning the winged insect corpse once every 1-2 weeks is met.

The shape of the inlet flow channel 2 plays a crucial role in the movement of the gas inside it, and also directly influences the effect of attracting flying insects. The shape of the intake runner 2 is mainly determined by the shapes of the outer wall surface of the cartridge main body and the inner wall surface of the housing 11.

The cross section gradually decreases along the airflow direction over the entire length of the intake duct 21 and the acceleration duct 22. The flow on all the cross sections of the whole inlet flow channel 2 is equal through the flow continuity equation, and the smaller the cross section is, the larger the flow speed is, because the flow is equal to the product of the flow speed and the cross section, the more the flying insect is close to the fan 3 after flying into the inlet flow channel, the more easily the flying insect is inhaled and killed.

An exhaust passage 23 is arranged from the air outlet of the fan 3 to the screen plate 5, the cross section of the exhaust passage 23 is gradually increased along the airflow direction, the flow velocity of the airflow is reduced, the airflow at the air outlet of the fan is restrained, the pressure loss of the airflow in the diffusion process is controlled, the kinetic energy of vortex dissipation airflow generated by the too fast expansion of the airflow is avoided, and the air resistance is generated at the air outlet of the fan, so that the performance of the fan is fully exerted. And influenced by the centrifugal action of the fan 3, the local wind pressure and wind speed at the outer ring of the inlet of the exhaust passage 3 are higher, after the section is enlarged and the pressure at the outlet end of the exhaust passage 23 is close to the atmospheric pressure and is basically stable, but a certain residual speed is reserved, so that the trapped winged insects are suppressed to reversely escape.
