Abstract
An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (μm).
Claims1
A portable nebulization device comprising:
- a metal chassis with tubular contours that form handles, a fixed flat base, and anti-vibration shoes located below said chassis;
- a first motor-fan assembly operative to produce air flow;
- a second motor-fan assembly operative to produce air flow;
- a tank configured to contain nebulization solution;
- a vibration system for the motor-fan assemblies, each vibration system including vibration cushioning pads and a spring cushioning system, the cushioning pads positioned at a lower portion of each motor-fan assembly, and the spring cushioning system positioned at an upper portion of each motor-fan assembly and fixed to the tank;
- an electric control including an electro-electronic valve and a micro-controller connected to a solenoid valve;
- an outlet;
- and
- a fan discharge assembly configured to:
- combine the air flows from the motor-fan assemblies into a single discharge air flow;
- direct a first portion of the discharge air flow directly into the tank;
- and
- direct a second portion of the discharge air flow to the outlet;
- wherein the tank is a curved cylindrical tank supported on the fixed flat base of the metal chassis, the tank having at a lower portion a valve to facilitate emptying and at an upper portion a lid, equipped with an auxiliary agitation system, being activated by a lever, and capable of agitating nebulization solution in said tank;
- wherein the first portion of the discharge air flow assists in pressurizing nebulization solution in the tank;
- wherein the first motor-fan assembly further comprises a first cowl configured to allow the channeling of the first motor-fan assembly air flow to the fan discharge assembly;
- wherein the second motor-fan assembly further comprises a second cowl configured to allow the channeling of the second motor-fan assembly air flow to the fan discharge assembly;
- wherein each motor-fan assembly comprises a two-stroke engine and a cowl for the fan;
- wherein each motor-fan assembly is fixed in a vertical position by means of flat sheet metal bases fixed to the chassis;
- wherein an upper portion of the tank comprises an air intake valve assembly;
- wherein the fan discharge assembly directs the first portion of the discharge air flow directly into the upper portion of the tank through the air intake valve assembly.
