  • the user does not need to accurately mount the filter-carrying mechanism 2 to the sliding rail on the fixed seat 11 when installing the filter-carrying mechanism 2, so that the filter-carrying mechanism 2 slides. Rotate by the track.
  • any numerical value recited herein includes all values of the lower and upper values in increments of one unit from the lower limit to the upper limit, and at least two unit intervals between any lower value and any higher value. Just fine. For example, if the number of components or process variables (eg, temperature, pressure, time, etc.) is stated to be from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate Values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly recited in the specification. For values less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be expressly stated, and all possible combinations of numerical values recited between the minimum and maximum values are considered to be explicitly described in this specification in a similar manner.

Abstract

La présente invention concerne une structure de remplacement d'un ensemble de noyau filtrant, un mécanisme de montage d'un boîtier de noyau filtrant, un filtre à eau et un dispositif de purification d'eau. La structure de remplacement d'un ensemble de noyau filtrant comprend : un ensemble de noyau filtrant (200) pourvu d'une partie d'actionnement capable de recevoir l'action une force extérieure ; une base fixe (100) pour le montage de l'ensemble du noyau filtrant (200) ; et un mécanisme de verrouillage doté d'une position de verrouillage où l'ensemble de noyau filtrant (200) est assemblé sur la base (100), et une position de libération où l'ensemble de noyau filtrant (200) est autorisé à se séparer de la base (100), la partie d'actionnement permettant au mécanisme de verrouillage de se déplacer vers la position de libération lorsqu'une force extérieure est appliquée. La structure de remplacement d'un ensemble de noyau filtrant, le mécanisme de montage du boîtier de noyau filtrant, le filtre à eau et le dispositif de purification d'eau peuvent permettre à un utilisateur de remplacer l'ensemble de noyau filtrant (200) d'un filtre à eau.
