Abstract

L'ensemble filtre (600) comprend une plaque de support de filtre (610) et un filtre (620). La plaque de support de filtre (610) comprend un cadre inférieur (611) et une bague de support (612). Le cadre inférieur (611) comprend une plaque inférieure (6111) et une paroi de support (6112). La paroi de support (6112) entoure la périphérie de la plaque inférieure (6111) et s'étend vers le haut. La bague de support (612) est disposée au-dessus du cadre inférieur (611). La bague de support (612) est reliée à la partie supérieure de la paroi de support (6112) et s'étend dans une direction horizontale tournée à l'opposé d'une cavité de montage de filtre (6113). Un dispositif d'alimentation en eau portable comprenant l'ensemble filtre (600) comprend en outre une coupe de stockage d'eau (100) ayant une extrémité ouverte (111), un couvercle de montage (200), un mécanisme d'ouverture et de fermeture (300), un mécanisme de bouton (400), et un réservoir de réception d'eau (500). L'ensemble filtre (600) recouvre l'extrémité ouverte (111). Le couvercle de montage (200) est monté amovible au niveau de l'extrémité ouverte (111) de la coupe de stockage d'eau (100). Le mécanisme d'ouverture et de fermeture (300) comprend une colonne de raccordement (310) passant de manière coulissante au travers d'une plaque de séparation (210), une plaque d'étanchéité (320) fixée à une extrémité de la colonne de raccordement (310), un coulisseau (330) fixé au niveau de l'autre extrémité de la colonne de raccordement (310), et un premier élément élastique (340) emmanché sur la colonne de raccordement (310). L'ensemble bouton entraîne le coulisseau (330) à coulisser dans une direction axiale du couvercle de montage (200) vers la plaque de séparation. Une extrémité du réservoir de réception d'eau (500) est emmanchée à demeure sur le couvercle de montage (200). Un second trou d'évent (512) et un second trou de sortie d'eau (511) sont disposés dans une position supérieure et une position inférieure d'une paroi latérale du réservoir de réception d'eau (500). Le second trou de sortie d'eau (511) communique avec un premier trou de sortie d'eau (212). Le second trou d'évent (512) communique avec un premier trou d'évent (213). Lorsque l'ensemble filtre fonctionne, de l'eau s'écoule dans le filtre (600) à partir d'un trou de filtre, ce qui permet d'obtenir une filtration. L'ensemble filtre (600) présente une structure simple et compacte.
