Embodiment Construction

[0038] In Figures 1-4, Venturi tubes 61 to 64 are shown respectively, each of which comprises: a Venturi tube body; an air inlet conduit 10; a conduit 20 for delivering the sprayed liquid; A spray area 30, the nozzle 15 of the air inlet duct 10 and the nozzle 25 of the liquid delivery duct 20 are located in this spray area 30; The spray area 30 is formed in the main body of the Venturi tube and each conduit stretches into the body. More specifically, each conduit is assembled into each cavity made on the main body of the Venturi tube respectively. A proper seal is achieved between the cylindrical outer surface and the corresponding bore. It can be seen that the liquid delivery conduit 20 extends into a spray zone 30 shaped as a cylindrical chamber. It can also be seen that the fluid delivery conduit 20 can be made as a containing part (i.e., an outer tube as shown in FIG. A contained part (ie, an inner tube as shown in FIG. 1 ), the nozzle 25 is located at the end of the con...

Abstract

The spray nozzle (65) has a liquid supply pipe (85) and an inlet pipe (10) for air under pressure. Each pipe presents a nozzle opened towards a spray zone (30) in which the air under pressure from the air inlet pipe sprays the liquid from the liquid supply pipe. An adjusting unit (70) adjusts a relative position of the nozzle of the liquid supply pipe with respect to the nozzle of the air inlet pipe. An independent claim is also included for a liquid diffusing device.

Description

technical field [0001] The present invention relates to a venturi tube for spraying and a device comprising the venturi tube. [0002] The invention is particularly suitable for use in liquid diffusion devices, eg for the dispensing of perfumes, liquid fuels and the like. [0003] It is an object of the present invention to achieve the dispersion of fine particles of liquid into the air. Background technique [0004] It should be noted that spraying (nebulization) refers to the size of liquid particles less than 1 micron, when the size of the dispersed liquid particles is between about 1 and 10 microns, it is atomization (atomization), and when their size is greater than about 10 microns Micron is fogging. [0005] Spray Venturi tubes are known, in which pressurized air ejects an aspirated liquid by virtue of the Venturi effect, the liquid being ejected and dispersed in the form of liquid particles. Each of these venturis is manufactured by machining one or several metal ...
