Title
(EN) PM2.5 VENTILATION FAN
(FR) VENTILATEUR SOUFFLANT POUR PARTICULES PM2.5

Abstract
(EN)
A PM2.5 ventilation fan is provided with a filtering device (1), wherein the filtering device (1) is provided with a bidirectional exhaust fan (37), a shutter (8), a water pump (6) and a water curtain nozzle (7). The shutter (8) is provided with a filtering water curtain (20). A controller (3) is used for controlling a motor (4) of the bidirectional exhaust fan (37) to rotate backward to exhaust indoor air to the outside. The controller (3) is used for controlling the motor (4) of the bidirectional exhaust fan (37) to rotate forward to suck outdoor fresh air into the inside. When the fresh air enters the inside, the fresh air is first filtered by the filtering water curtain (20) of the shutter (8), and the filtering water curtain (20) is used for absorbing dust and PM2.5 of the outdoor air.

L'invention concerne un ventilateur soufflant pour particules PM2.5 comportant un dispositif de filtrage (1), dans lequel le dispositif de filtrage (1) comporte un ventilateur d'extraction bidirectionnel (37), un volet (8), une pompe à eau (6) et une lance à rideau d'eau (7). Le volet (8) comporte un rideau d'eau de filtrage (20). Un dispositif de commande (3) sert à commander un moteur (4) du ventilateur d'extraction bidirectionnel (37) à des fins de rotation inverse pour évacuer l'air intérieur vers l'extérieur. Le dispositif de commande (3) sert à commander le moteur (4) du ventilateur d'extraction bidirectionnel (37) à des fins de rotation avant pour aspirer l'air frais extérieur vers l'intérieur. Quand l'air frais entre dans l'intérieur, l'air frais est tout d'abord filtré par le rideau d'eau de filtrage (20) du volet (8), et le rideau d'eau de filtrage (20) sert à absorber la poussière et les particules PM2.5 de l'air extérieur.
