Title
(EN) FILTRATION DEVICE HAVING A LATCH MECHANISM
(FR) DISPOSITIF DE FILTRATION DOTÉ D'UN MÉCANISME DE VERROUILLAGE
Abstract
(EN) A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.
(FR) Un dispositif de filtration peut comprendre un élément de filtre et un boîtier qui est conçu pour recevoir l'élément de filtre. L'élément de filtre peut comprendre un boîtier doté d'une première surface extérieure et d'une bride reliée à la première surface extérieure. La bride peut comprendre une pluralité d'éléments d'encliquetage. Un élément d'encliquetage, de la pluralité d'éléments d'encliquetage, peut comprendre un point d'appui faisant saillie à partir de la bride et un levier monté sur le point d'appui. Le boîtier peut comprendre une coque dotée d'une seconde surface externe et d'une pluralité d'éléments de rampe. La pluralité d'éléments de rampe peut être reliée de manière fixe à la seconde surface externe et peut être configurée pour venir en prise avec la pluralité d'éléments d'encliquetage de l'élément de filtre. Un élément de rampe, de la pluralité d'éléments de rampe, peut comprendre une surface inclinée qui s'étend depuis la seconde surface extérieure selon un angle aigu par rapport à la seconde surface extérieure.
