FR2851721A1 - Portable device for destruction of biting flying insects, uses battery-powered electric motor with flexible cutter line attached to rotor - Google Patents

Abstract

The device has a handle (1) housing batteries (2) and fitted with a on-off switch (3), a shaft (4) extending from the handle to the head of the device. The head has an electric motor (5) with flexible cutter line (8) attached to its rotor and a circular shroud (7) at the periphery of the lines. The spinning lines physically destroy the insect when the electric motor is activated.

Description

The present invention relates to a portable device allowing the

  selective destruction of flying insects.

  Today, the traditional means used against flying insects are mainly aerosol cans (relatively harmful to humans and the environment) and electrical wall outlets for indoor use only. It should be said that these solutions are not adapted to the unexpected presence of a wasp, a horsefly, a hornet, where it is necessary to act quickly, in a room, a kitchen etc ..., or just a mosquito that bothers you day or night. 10 Often used, the cloth, which can be very dangerous. The mobile and portable device according to the invention overcomes this drawback, inside and outside, naturally.

  According to a first characteristic, it comprises a handle comprising a housing for 2 batteries and a trigger, a handle, an electric reduced motor, a rotor with flexible wires and two protective casings, one for the rotor with flexible wires. , the other for the reduced engine. Thus, using this device, the user, by pressing the trigger, activates the rotor to instantly eliminate all types of unwanted insects. This device is entirely made by plastic injection (handle, handle, 20 housings).

  According to particular embodiments: - the handle (including the battery compartment and the trigger), the handle and the motor protection casing are one piece, in plastic injection. The motor protection casing has edges of around 25 cm. This forms the first part.

  - the rotor protection casing forms the second part, which is also a plastic injection molded part. For final assembly, the rear part of the rotor protection casing sticks flat to the edges of the motor protection casing. The flexible wire rotor is fixed on the axis of the motor using a screw.

  - The protective casing of the rotor may include in its bottom, openings to increase the suction of insects.

  - a grid behind the rotor protection casing can be installed to retain insects likely to pass through flexible wires.

  The accompanying drawings illustrate the invention: Figure 1 shows the device of the invention.

  Figure 2 shows a variant of this device.

  With reference to these drawings, the device comprises a handle (1), on this handle (1), there is on one side the battery compartment (2) and on another side, the trigger (3). Then the handle (4) which connects the motor protection casing (5). The battery compartment (2) contains 2 LR6 type batteries.

  These batteries power the reduced electric motor (6) which has a nominal voltage of 3 V, a maximum efficiency consumption of 1.0 A and an idle speed of 12300 'min. The reduced motor (6) and the battery compartment (2) each have two connection terminals. Two electric wires are welded, from the motor (6) to the battery compartment (2). One of the electrical wires is sectioned at the location of the trigger (3), then connected to the input and output of the trigger (3). This will allow, by pressing the shutter button at the press of a button, to operate the motor (6) then the rotor (8) surrounded by the rotor protection casing (7).

  In the embodiment according to Figure 2, the rotor protection casing (7) has openings in order to have greater suction power. It is made up of five branches (9) distributed over the entire diameter of the protective casing (7). Still on the rotor protection casing (7), with the branches (9) 25 in number, there is a grid (10) of the same diameter as the rotor protection casing (7) in order to retain possible insects passed through the rotor (8).

  By way of nonlimiting example, the device will have dimensions of the order of 3 cm in width for the handle and 2.5 cm in diameter for the handle. The rotor protection casing will have a dimension of the order of 13 cm in diameter. The assembly will have a height of the order of 39 cm.

  The device according to the invention is particularly intended for the selective and natural elimination of dangerous or undesirable flying insects.
