    摘要: A system for purifying air is provided comprising a ceiling fan with a plurality of blades and a prism shaped box positioned in a lengthwise manner atop an upper surface of a first blade of the plurality. A leading panel of the box opens when the first blade begins to move. The system also allows airborne particles to enter the box and traps the particles inside the box. The leading panel is located on a forward-facing panel of the prism shaped box. The leading panel opens based on air resistance met based on motion of the first blade. The box contains porous filtering material. The box traps the particles via at least the filtering material. The box is made of cardboard and remains flat with the leading panel in collapsed state when the fan is not turning. An upper surface of the box raises when the fan begins to turn.

    摘要: A damper for fan includes a frame (61) defining a passage for an airflow, having an inlet and an outlet, and a pair of flaps (62, 63) hinged to the frame (61) about respective rotation axes (x1, x2) parallel to each other, the flaps being rotatable between an open and a closed position, for opening and closing the passage, respectively. Each of the flaps includes a concave portion (62c, 63c) and a convex portion (62d, 63d) arranged on opposite axial halves of the respective flap, wherein in the closed position the concave portion (62c, 63c) has a concavity facing the inlet of the passage and a convexity facing the outlet of the passage, and the convex portion (62d, 63d) has a convexity facing the inlet of the passage and a concavity facing the outlet of the passage, and wherein the concave portion (62c) and the convex portion (62d) of one of the flaps have an axial arrangement reversed with respect to the concave portion (63c) and the convex portion (63d) of the other flap.

    摘要: A fan assembly includes a motor having an output shaft that defines a rotation axis, a plurality of fan blades coupled to the output shaft and configured to be rotated by the output shaft when the motor is actuated to generate airflow, a fan shroud surrounding the plurality of fan blades, and a handle disposed on the fan shroud. The handle comprises a base and a rotating handle structure rotatable about the base. The base includes a first gripping portion configured to be gripped by a user, and the rotating handle structure includes a second gripping portion configured to be gripped by the user.

    摘要: The invention employs blades featuring multiple holes. The metal decoration for coupling conceals perforated sections, which ease the mounting and alignment for screws installation. The blade holder incorporates two or more slots for screws to slide through the decoration cover, securing the blade assembly onto the fan motor for assembly and operation. The decoration cover has a minimum of two holes for alignment screw installation and one hole for preassembling and fastening it onto the blade. Alignment screws serve a dual purpose by sliding into the blade holder's slots and installing the blade assembly. This not only aligns the blade holder but also temporarily holds the assembly, freeing the installer's hands for subsequent installation steps. This simplifies the process, minimizes installer fatigue and allowing the use of both hands to handle screws, making it a time-efficient and straightforward task. The installation difficulty then reduces from 9 to 1.

    摘要: A turbomachine includes an annular casing and a fan disposed inside the annular casing and mounted for rotation about an axial centerline. The fan includes fan blades that extend radially outwardly toward the annular casing. The fan blades include a composite blade including a composite airfoil section having an airfoil leading edge and an airfoil trailing edge, a root attached to the composite airfoil section, and a blade shank therebetween. A metallic leading edge shield covers an axially extending portion of the composite airfoil section including at least a portion of the airfoil leading edge and covers a radially and chordwise extending portion of the airfoil leading edge of the blade shank. The fan has an average chord fan width according to a first performance factor. The fan has a quantity of fan blades according to a second performance factor.
