AUTOMATED DEVICE FOR THE TARGETED SPRAYING OF ACTIVE MATERIAL
Device ( 1 ) for spraying active material comprising a case ( 2 ) fixed on a support ( 3 ), said case ( 2 ) containing a liquid solution containing at least one active material in a tank ( 7 ), said solution being ejected through an ejection orifice ( 4 ), said tank ( 7 ) being equipped with an activatable diffusion mechanism ( 10 ), which communicates with an electronic circuit ( 10 ), powered by a battery ( 11 ), the activation of which triggers spraying, characterized in that the ejection orifice ( 4 ) is connected to a tubular duct with a length of between 5 and 70 cm provided with at least one outlet orifice ( 5 ′) for offsetting the ejection of said active material in the form of fine liquid particles.
1 . A device comprising a case fixed on a support, the case containing a liquid solution containing at least one active material in a tank, the solution being ejected through an ejection orifice, the tank being equipped with an activatable diffusion mechanism, which communicates with an electronic circuit, powered by a battery, the activation of which triggers spraying of the active material, wherein the ejection orifice is connected to a tubular duct with a length of between 5 and 70 cm provided with at least one outlet orifice.
2 . The device according to claim 1 , wherein the tubular duct has an internal diameter ranging from 0.2 to 5 mm.
3 . The device according to claim 1 , wherein the tubular duct has an angle of curvature with respect to a baseplate of between 30° and 120°.
4 . The device according to claim 1 , wherein the tubular duct contains an ejection nozzle with a diameter of between 0.2 mm and 2 mm at its outlet orifice.
5 . The device according to claim 4 , wherein the activatable diffusion mechanism is a solenoid valve, a spray nozzle of which is offset and is fixed to a free end of the tubular duct.
6 . The device according to claim 1 , wherein a sound intensity generated by the ejection of the liquid through the tubular duct is less than 30 decibels.
7 . The device according to claim 5 , wherein the electronic circuit controls the actuation of an electromagnetic coil of the solenoid valve in order to trigger the spraying.
8 . The device according to claim 1 , wherein the tubular duct has an accordion-like structure over at least part of its length.
9 . The device according to claim 1 , wherein the tubular duct comprises a plurality of perforations.
10 . The device according to claim 1 , wherein the tubular duct comprises at least one branch.
11 . The device according to claim 1 , wherein the active material is selected from an insecticide, a repellent, an odoriferous agent, a cosmetic agent, an anti-itch agent, or the mixtures thereof.
12 . The device according to claim 1 , wherein the electronic circuit allows the diffusion mechanism ( 10 ) to be remotely controlled.
13 . The device according to claim 12 , wherein the remote control of the diffusion mechanism is effected by means of a remote control, a radio system, or a Wi-Fi system.
14 . A method for improving spraying of an active material comprising using the device according to claim 1 for spraying a volume of liquid on a target.
15 . The method according to claim 14 , wherein the active material is a repellant or an insecticide.
16 . The method according to claim 14 , wherein the active material is continuously or intermittently sprayed onto the target.
17 . The method according to claim 14 , wherein the volume of the liquid sprayed is from 10 to 400 μL per jet over a time interval of 2 to 10 seconds, and wherein the quantity of active material is from 0.01 to 50% by weight of the volume of liquid.
