Abstract

Mécanisme de détection d'installation négligée pour des éléments filtrants d'un collecteur de poussières et collecteur de poussières. Le mécanisme de détection d'installation négligée comprend : un élément filtrant avant (10) et un élément filtrant arrière (20), qui viennent en butée l'un contre l'autre après avoir été installés de manière appropriée et qui peuvent être séparément démontés ; et un ensemble de prévention d'installation négligée (30) situé sur la partie supérieure de l'élément filtrant arrière (20). Après une installation appropriée, l'élément filtrant arrière (20) et l'élément filtrant avant (10) exercent une pression contre l'ensemble de prévention d'installation négligée (30) et déclenchent l'ensemble de prévention d'installation négligée (30). L'élément filtrant avant (10) et l'élément filtrant arrière (20) sont séparément assemblés, et la structure non intégrée facilite le remplacement de l'élément filtrant avant (10) ou de l'élément filtrant arrière (20) ; l'ensemble de prévention d'installation négligée (30) disposé sur la partie supérieure de l'élément filtrant arrière (20) peut détecter l'installation négligée de l'élément filtrant avant (10) et/ou de l'élément filtrant arrière (20) ; lorsque l'installation de l'un de l'élément filtrant avant (10) et de l'élément filtrant arrière (20) est négligée, l'installation négligée de l'un ou de l'autre peut être détectée uniquement par l'ensemble de prévention d'installation négligée (30) ; et les structures de l'élément filtrant avant (10) et de l'élément filtrant arrière (20) sont améliorées, ce qui permet d'efficacement éviter une installation opposée de l'élément filtrant avant (10) et de l'élément filtrant arrière (20).
