Abstract
The utility model belongs to the technical field of insect-catching appliances, in particular to an air ventilating duct of a phosgene flying insect trapping device and discloses the air ventilating duct of the phosgene flying insect trapping device. The air ventilating duct of the phosgene flying insect trapping device comprises a cylinder body, and a fan capable of producing downward wind force is arranged at the upper end opening of the cylinder body. A cross rod is arranged at one end, far away from the fan, inside the cylinder body. An overturn type anti-escaping board is arranged on the cross beam, and the anti-escaping board can rotate along the cross beam under the action of external force. The air ventilating duct of the phosgene flying insect trapping device is simple in structure and convenient to use, and can prolong the service life of the whole phosgene flying insect trapping device.
Description
Technical field
The utility model belongs to insect-catching apparatus technical field, relates in particular to a kind of ventilation shaft of phosgene winged insect trapper.
Background technology
The winged insects such as mosquito, fly, moth often affect people's life.Effectively removing indoor winged insect how safely, is the problem that the control of insect worker thinks deeply always.In the past few decades, in order to eliminate the winged insects such as mosquito, fly, moth, people have invented electric shock type mosquitos and flies trapper, the sticking formula mosquitos and flies trapper of catching.Yet, these trappers in use since lure the source single or design unreasonable, unsatisfactory to the predating efficiency of mosquito, fly, moth etc.At present, the maximum of use are the phosgene winged insect trappers, and the ventilation shaft of this type of trapper is because fan and convertible anti-escape that plate leans on nearer, thus the wind-force that fan produces cause sometimes convertible anti-escape plate do not have winged insect drop to above the time also can overturn.So that convertible anti-to escape plate constantly in running order, affect the service life of whole device.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of ventilation shaft of phosgene winged insect trapper is provided, and its technical scheme is as follows:
A kind of ventilation shaft of phosgene winged insect trapper, comprise cylindrical shell, the upper end open place of described cylindrical shell is provided with the fan that can produce downward wind-force, end away from fan in the described cylindrical shell is provided with cross bar, described cross bar is provided with the convertible anti-plate of escaping, and describedly convertiblely anti-ly escapes plate and can rotate around cross bar under external force.
The ventilation shaft of the phosgene winged insect trapper that the utility model provides, so that fan and the convertible anti-distance of escaping between the plate reach maximization, thereby so that above the wind-force of fan can't be applied to, when not having winged insect to drop in the above, convertiblely anti-ly escape plate and can not overturn.
The utility model is simple in structure, and is easy to use, can increase simultaneously whole phosgene winged insect trapper service life.
