Embodiment Construction

[0026] According to the present invention (more specifically, Figure 5 and 6 As shown in the first feature, the nozzle is in all respects compatible with figure 2 and 3 The same as the prior art nozzle shown in . However, it is different and characterized in that the blades 7 are curved. This curvature facilitates the circular movement of the air entering the chamber 3 in the vortex. The presence of this vortex allows for a better spraying of the treatment product, resulting in a better uniformity of the droplets and without a too broad particle size spectrum. this is in Figure 7 clearly visible in the Figure 7 shows from Figure 5 and 6 Particle size analysis of the jet obtained in a nozzle with curved vanes 7 . Particle size analysis is presented in the form of a particle size spectrum, the abscissa of the bar graph is the droplet diameter (expressed in microns), and the ordinate is the frequency (expressed in percent), and the ordinate of the continuous curve i...

Abstract

A spray nozzle (1) for an apparatus for aerially disinfecting surfaces, that is substantially rotationally symmetrical about an axis (2), comprising a substantially cylindrical chamber (3), the axis of which coincides with the axis (2) of the nozzle (1), a pipe (4) opening in the bottom (5) of the chamber (3), preferably at the centre of said bottom (5), suitable for supplying a treatment product,an air inlet (6) extending around the periphery of the chamber (2), fins (7) arranged between the air inlet (6) and the chamber (3), and a substantially conical diffuser (8) that opens towards the outside, has an axis aligned with the axis (2) of the nozzle (1), and is attached to the chamber (3) on the side opposite the bottom (5), where the fins (7) are curved.

Description

technical field [0001] This patent application claims priority from French patent application FR 17 / 70945 filed September 8, 2017, which is hereby incorporated by reference. [0002] The present invention relates to the field of disinfection of environments by means of air. It is known in the art to spray treatment products such as antiseptic products by mixing them with propellant air and allowing them to diffuse into the environment in the form of fine droplets, thus treating surfaces. Background technique [0003] For this purpose, it is known to use a device 20 such as figure 1 Apparatus shown in , which includes treatment product storage tank 21, conveying means (such as including pump 22 and pipeline 25 (or 4) for sending this product to nozzle 24 (or 1)), and capable of blowing air to all The electric fan 23 of the nozzle 24. The function of the nozzles 24 is to spray the treatment product, mix it with the propellant air, and allow the air / product mixture to diffus...
