Description

Fan for insecticidal lamp

Technical Field

The utility model relates to the technical field of insecticidal lamps, in particular to a fan for an insecticidal lamp.

Background

The insect killing lamp is a special device which uses insect attracting light sources in a specific spectral range which are sensitive to insects according to the characteristic that insects have phototaxis, attracts insects, can effectively kill the insects, reduces the insect disease index, and prevents and treats insect pests and insect-borne diseases, and is mainly used for killing the insect pests and reducing the use of pesticides.

Like chinese patent No. ZL201920591825.3, just disclose an insecticidal lamp fan, insecticidal lamp fan includes the aircraft bonnet, the aircraft bonnet bottom inlays to be established and installs the otter board, the aircraft bonnet bottom is fixed with transparent end cover, be equipped with the adsorption equipment who upwards promotes the air current in the aircraft bonnet, adsorption equipment is including fixing the motor on the aircraft bonnet, the output shaft drive of motor has the axial fan who is located directly over the otter board, adsorption equipment's effect is that the messenger mosquito can be adsorbed to the end cover by ascending air current in, ascending air current also plays the guide effect to the mosquito, realize adsorbing the insect catching. The structural disadvantage of the adsorption fan is that the axial flow fan blade has a simple structure, the adsorption guiding function is general, and mosquitoes are at risk of being incapable of being completely adsorbed.

Disclosure of Invention

Aiming at the defects in the prior art, the technical problem to be solved by the utility model is how to improve the adsorption capacity of the insecticidal lamp fan, and the specific technical scheme is as follows:

a fan for insecticidal lamp, includes mounting panel, motor, hub shell, guide vane, current collecting plate and bottom plate, installs the motor in the mounting panel, and motor drive hub shell rotates, and the polylith guide vane is installed to hub shell periphery side, and current collecting plate is installed to the guide vane top, and current collecting plate center is equipped with the current collecting mouth, and guide vane below mounting plate forms the wind groove between guide vane and the guide vane, and current collecting mouth guide wind gets into each wind groove.

As a preferable scheme of the utility model, a plurality of guide vanes are spirally distributed, and the air duct is of a gradual-change type increasing structure with small inner side and large outer side.

As a preferred embodiment of the present utility model, the flow deflector is integrally formed with the flow collecting plate or the flow deflector is detachably mounted to the flow collecting plate.

As a preferred embodiment of the present utility model, the deflector is integrally formed with the base plate or the deflector is detachably mounted to the base plate.

As a preferable scheme of the utility model, the bottom of the guide vane is provided with a positioning strip, the bottom plate is provided with a positioning hole, and the guide vane is detachably arranged on the bottom plate through the matching of the positioning strip and the positioning hole.

As a preferred embodiment of the utility model, the axle housing is below the guide vane.

The beneficial effects are that: when the fan for the insect killing lamp is used, the motor drives the shaft housing to rotate, the shaft housing drives the guide plates, the current collecting plates and the bottom plate to synchronously rotate, a plurality of wind grooves are formed due to the isolation effect of the guide plates, wind enters each wind groove after being guided by the current collecting ports, the adsorption guiding capability is strong, mosquitoes can be adsorbed well, and the structural design is ingenious and reasonable.
