Description

Technical Field

[0001] The utility model relates to the field of insect extermination devices, in particular to an insect attracting and extermination device for plant protection. Background Art

[0002] Plant protection insect trapping and killing devices primarily leverage the physiological and behavioral characteristics of pests, attracting them through specific trapping methods and then inactivating them through physical or biological methods. Wind-sucking insecticidal lamps, among them, exploit insects' phototaxis and sensitivity to light sources of specific wavelengths, using light waves to lure adult pests toward the lamp. Simultaneously, a built-in fan generates strong airflow, creating a negative pressure zone that rapidly draws the pests into a collector. Within the collector, the insects are dried and dehydrated, achieving their intended purpose.

[0003] When the exhaust fan of the wind-suction insecticidal lamp uses airflow to suck in approaching flying insects, the concentration and stability of its airflow are relatively poor, which increases the generation of vortices and turbulence and reduces the exhaust efficiency. As a result, the flying insects may escape in certain areas with weaker suction due to sensing abnormal changes in wind speed or uneven suction distribution.

[0004] Therefore, in view of the fact that the concentration and stability of the wind flow generated by the above-mentioned wind-suction insect-killing lamp are relatively poor, flying insects may escape from certain areas with weak suction due to sensing abnormal changes in wind speed or uneven suction distribution. A plant protection insect attractant and insect-killing device can be designed to solve the above problem. Utility Model Content

[0005] In order to overcome the problem that during the operation of the wind-suction insect-killing lamp, if the airflow generated by it is relatively poorly concentrated and stable, flying insects may escape in certain areas with weak suction due to sensing abnormal changes in wind speed or uneven suction distribution, thereby reducing the insect-killing efficiency of the device.

[0006] The technical solution of the utility model is: an insect attracting and killing device for plant protection, including an exhaust fan, an air collecting hood installed on the outside of the exhaust fan, a support hood fixed to the upper end of the air collecting hood, and also including a trapping component arranged at the lower end of the air collecting hood and the inner side of the support hood; and an anti-escape component installed on the upper end of the support hood; the trapping component includes a chamfered slope, a spiral groove, a collecting tube, an exhaust hole, a thread, a water holding tray, and a lamp bead; the anti-escape component includes an insertion frame, a slide, a filter screen, a pull ring, a jack, a water supply trough, a hose, a small water pump, and an atomizing nozzle.

[0007] Preferably, after starting the exhaust fan, the chamfered surface with a wider upper part and a narrower lower part makes it easier for the outside air to converge evenly to the center of the device, and the spiral groove makes the wind flow more concentrated and stable, so as to improve the exhaust efficiency, make the air flow smoother, and reduce the generation of eddies and turbulence, so that the suction is evenly distributed and more concentrated, so that it is more difficult for flying insects to escape after entering the suction range, and the small water pump will also draw water from the lower end of the collection cylinder and the water holding tray through the hose, and send it to the atomizing nozzle, so that the water mist can wet the wings of the flying insects within the suction range, making it more difficult for the flying insects to escape, and the flying insects will be sucked into the collection cylinder together with the flying insects, so that the captured flying insects will be drowned by water, and the water will be filtered by the filter when it flows downward and then drawn by the hose to achieve water recycling.

[0008] Preferably, a chamfered surface is provided on the inner side of the air collecting hood, and the upper part of the chamfered surface is wider and the lower part is narrower; a plurality of spiral grooves are provided on the chamfered surface, and the exhaust fan is installed at the lower end of the spiral groove.

[0009] Preferably, a collecting tube is provided in the gap at the lower end of the air collecting hood; an exhaust hole is provided on the collecting tube; and a thread is provided on the upper end of the collecting tube.

[0010] Preferably, the lower end of the collecting cylinder is fixedly connected to a water holding tray, and the lower end of the collecting cylinder is communicated with the water holding tray; and a lamp bead is installed at the upper end of the inner side of the support cover.

[0011] Preferably, four groups of insertion frames are fixedly connected to the inner wall of the collecting cylinder; a slide is slidably connected inside the insertion frame; and a filter is installed on the upper end surface of the slide.

[0012] Preferably, pull rings are fixed on both sides of the upper end of the slide; a socket is provided on one side of the upper end of the water tray; and a water replenishment groove is provided on the other side of the upper end of the water tray.

[0013] Preferably, an atomizing nozzle is installed on the upper end of the support cover; the upper end of the atomizing nozzle is connected to a small water pump; a hose is connected to the small water pump; and the end of the hose is inserted into the socket.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up trapping components and anti-escape components, the outside air can be more evenly gathered to the center of the device, and the wind flow can be more concentrated and stable, so as to improve the exhaust efficiency and make the air flow smoother, so as to reduce the generation of eddies and turbulence, so that the suction force is evenly distributed and more concentrated, so that it is more difficult for flying insects to escape after entering the suction range.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See also Figures 1-6 The utility model provides an embodiment: an insect trapping and killing device for plant protection, comprising an exhaust fan 1, an air collecting hood 2 installed on the outside of the exhaust fan 1, a support hood 3 fixed to the upper end of the air collecting hood 2, and also comprising a trapping component arranged at the lower end of the air collecting hood 2 and the inner side of the support hood 3; and an anti-escape component installed at the upper end of the support hood 3; the trapping component comprises a chamfered slope 401, a spiral groove 402, a collecting tube 403, an exhaust hole 404, a thread 405, a water holding tray 406, and a lamp bead 407; the anti-escape component comprises an insertion frame 501, a slide 502, a filter screen 503, a pull ring 504, a jack 505, a water supply groove 506, a hose 507, a small water pump 508, and an atomizing nozzle 509.

[0025] See also Figure 2-Figure 6In this embodiment, a chamfered slope 401 is provided on the inner side of the air collecting cover 2, and the upper part of the chamfered slope 401 is wide and the lower part is narrow; a plurality of spiral grooves 402 are provided on the chamfered slope 401, and the exhaust fan 1 is installed at the lower end of the spiral groove 402; a collecting tube 403 is provided in the gap at the lower end of the air collecting cover 2; an exhaust hole 404 is provided on the collecting tube 403; a thread 405 is provided on the upper end of the collecting tube 403; a water collecting pan 406 is fixedly connected to the lower end of the collecting tube 403, and the lower end of the collecting tube 403 is connected to the water collecting pan 406; a lamp bead 40 is installed on the upper end of the inner side of the support cover 3 7; Four groups of insertion frames 501 are fixedly connected to the inner wall of the collection tube 403; a slide 502 is slidably connected in the insertion frame 501; a filter screen 503 is installed on the upper end surface of the slide 502; pull rings 504 are fixedly connected on both sides of the upper end of the slide 502; a socket 505 is provided on one side of the upper end of the water storage tray 406; a water supply groove 506 is provided on the other side of the upper end of the water storage tray 406; an atomizing nozzle 509 is installed on the upper end of the support cover 3; the upper end of the atomizing nozzle 509 is connected to a small water pump 508; a hose 507 is connected to the small water pump 508; the end of the hose 507 is inserted into the socket 505.

[0026] When in use, water is added to the water tray 406 and the collection tube 403 through the water supply tank 506, and the water level exceeds the filter 503 but does not exceed the exhaust hole 404, and then the end of the hose 507 is inserted into the socket 505;

[0027] After the exhaust fan 1 is started, the chamfered inclined surface 401 with a wider upper portion and a narrower lower portion makes it easier for the outside air to converge evenly toward the center of the device, while the spiral groove 402 makes the wind flow more concentrated and stable, thereby improving the exhaust efficiency, making the air flow smoother, and reducing the generation of eddies and turbulence, so that the suction force is evenly distributed and more concentrated, making it more difficult for flying insects to escape after entering the suction range. In addition, the small water pump 508 also draws water from the lower end of the collection cylinder 403 and the water holding tray 406 through the hose 507, and sends it to the atomizing nozzle 509, so that the water mist wets the wings of the flying insects within the suction range, making it more difficult for the flying insects to escape. The flying insects are then sucked into the collection cylinder 403 together with the flying insects, so that the captured flying insects are drowned by the water. When the water flows downward, it is first filtered by the filter 503 and then drawn by the hose 507, so as to realize the recycling of water.

[0028] When cleaning the equipment, pull the end of the hose 507 out of the socket 505, and then remove the collecting tube 403 which is fitted with the air collecting cover 2 through the thread 405, so that the dead insects and sewage can be poured out, and the slide 502 can be pulled out through the pull ring 504 to facilitate the cleaning of the filter 503.

[0029] Through the above steps, by setting up the trapping component and the anti-escape component, the outside air can be more evenly gathered to the center of the device, and the wind flow can be more concentrated and stable, so as to improve the exhaust efficiency, make the air flow smoother, and reduce the generation of eddies and turbulence, so that the suction is evenly distributed and more concentrated, so that it is more difficult for flying insects to escape after entering the suction range. At the same time, the wings of flying insects in the suction range can be wetted by water mist, making it more difficult for flying insects to escape, and the water in the water mist can be recycled.
