Short description: Device for emitting light and electrocuting insects

DESCRIPTION

The invention relates to a device for emitting light and electrocuting insects.

Commonly known for killing (flying) insects - hereinafter referred to as flies for convenience - include the traditionally known adhesive flycatchers, insect traps, electric or non-electric fly swatters and devices equipped with a UV light source and a high-voltage supply.

The variant in which the flies are electrocuted is often more "insect-friendly": the insects are usually killed immediately. With the electric fly swatter, the insects are stunned after which they can still be killed by applying mechanical pressure or hitting them hard.

The present invention concerns the type of device that is designed as a combination of an electric fly killer and a light source, brought together in a housing that, together with its electrical connection, resembles that of a conventional "incandescent lamp" (nowadays increasingly equipped with LEDs instead of a filament as a light-generating element). The design of the electrical connection also corresponds to that of a conventional lamp, namely a so-called Edison thread connection.

This type of device is known per se from the cc-3 patents CN1105531643 in the name of Zhaoqing Jiuliang

Photoelectric. Tech Co Ltd and US2018/05234%A1 in the name of

Zheng Jun et al. Both devices show a device equipped with lighting components and high-voltage components, respectively. designed for radiating light and electrocuting unwanted flying insects. Both known devices have the disadvantage that dead insects fall down the outside of the housing of the device. Furthermore, in the known devices the high-voltage electrodes are quite is poorly shielded against contact, namely, in both cases, by means of a carbon with bars and openings in between, through which the high-voltage electrodes can be contacted via a pointed object. The known devices are also for the same reason not really suitable for use outdoors or in humid environments,

The present invention aims to ensure that the electrocuted insects are collected within the direction of travel and therefore do not fall down and, for example, end up in the food. Furthermore, according to the invention it is provided that the space in which the insects. collected can be opened very easily and intuitively, after which the killed insects can be removed and the collection space can be cleaned simply and safely. The invention aims to ensure that the enclosures and design of the housing do not or hardly deviate from those conventional {incandescent} lamps.

And furthermore, the invention aims to provide a configuration

ration in which the high-voltage electrodes are covered much better and more safely, so that the risk of contact is much smaller, while the device according to the invention is also more suitable for use outdoors and in damp
