<p>A filter structure for a dust collection device, integrally formed with a functional venturi for collecting and capturing and then detaching and separating dust particles and dust pollutants, comprises: an external periphery portion (202) having a structure in which the functional venturi (200) is mounted above an upper cap (120) coupled to the top portion of a filter (110) and a lower cap (130) coupled to the bottom portion of the filter (110), and comprising a connecting body (140) having a specific length for integrally penetrating the upper cap (120) and the functional venturi (200) and connecting same, wherein the top portion of the connecting body (140) comprises a bolt (142) having a screw thread, and wherein the functional venturi (200) has a tapered form so that the top and bottom of the inside thereof are open in the lengthwise direction, and the inner diameter of an upper end inlet decreases toward the bottom end; a perpendicular column (220), which stands perpendicularly so as to protrude through a space open at the center of the external periphery portion (202), has an open lower surface so that the connecting body (140) can be inserted therein, and which defines a lengthwise space portion on the inside thereof; and one or more support bodies (210) for supporting so that the perpendicular column (220) stands in the open space at the center of the external periphery portion (202) by connecting the perpendicular column (220) and one inner surface of the external periphery portion (202), wherein, when coupled to the connecting body (140), the lengthwise space portion in the perpendicular column (220) is provided with a screw thread on one side surface at the upper end where the bolt (142) of the connecting body (140) is coupled.</p> |
