Abstract
The utility model relates to a scavenger fan, which is composed of a motor, fan blades, a wind shielding cover, fastening pieces, etc. The utility model is characterized in that the wind shielding cover is arranged and the wind frame of the wind shielding cover is in square figure or a circular ring shape; the lateral face of the wind frame is provided with an air outlet and the inner side is a convex surface in reverse direction. The motor is arranged in a concave cavity from a bell mouth at the external side of the wind shielding surface; one end of a motor shaft extends into the wind frame of the wind shielding cover through the center of the wind shielding surface to be connected with the fan blades; the utility model is started and stopped by adopting the method that the fan blades are closed automatically or a plurality of kinds of window grille piece are closed; the wind shielding cover can be quickly installed by the fastening pieces. The utility model has the advantages of novel design, natural wind shielding, convenient disassembly, convenient assembly and long service life, and the utility model can be wiped easily.
Description
The utility model is about ventilation fan.
At present, the ventilation fan of market sale has several deficiencys, does not have wind shield, and the wiping difficulty is damaged easily.
The purpose of this utility model provides a kind ofly can keep off natural wind, and wiping is very convenient, the ventilation fan of long service life.
Its solution is: a wind shield is set, and its wind frame is square or ring, and there is exhaust port its wind frame side, and its frame is connected with the fastening piece of window border, and its face inboard of keeping out the wind is reverse convex surface; From the face outside of keeping out the wind motor is installed in the re-entrant cavity, its motor shaft one end stretches in the wind frame by the center hole of the face of keeping out the wind, and is connected with flabellum.
The reverse convex surface of the face that the keeps out the wind cylinder surface that to be the circular cone table top link to each other with top with it, motor is positioned at cylindrical cavity.
Fastening piece base plate or outer bolt are fixed on window border, and movable bolt that links to each other with base plate or outer bolt or inner bolt are connected and lock the wind shield frame, and the wind shield frame has hole or the breach that is complementary with fastening piece.
The other end of motor shaft is equipped with little flabellum, plays cooling motor; The face outside horn mouth that keeps out the wind is provided with the protection apron of a band ventilated port.
The window bar sheet is tabular or roller shutter shape and wind shield frame or cover flexible connection, and when closing, the window bar sheet has hidden flabellum.
The window bar sheet is a tubulose and circle side wind shield wind frame is complementary, and corresponding exhaust port is all arranged, and stirs the window bar sheet, exhaust port is communicated or is separated by.
According to the ventilation fan of above conceptual design, be mainly reflected in the brand-new design of wind shield; Oppositely the conical face that keeps out the wind conforms to hydromechanical principle, and air draft is effective; Motor is installed in and is difficult in the face outer concave body that keeps out the wind polluting; Wiping is very convenient in the wind frame; The fastening piece of energy fast opening makes integral demounting and peripheral wiping easily accomplish again; Longer service life.
Accompanying drawing has been described an embodiment of the present utility model.
Wherein 1-motor, 2-flabellum, 3-wind shield, 4-fastening piece, 5-window bar sheet, 6-weather shield.
Referring to accompanying drawing, the utility model is made up of motor 1, flabellum 2, wind shield 3, fastening piece 4, window bar sheet 5; Wind shield 3 wind frames are ring, and there are five exhaust ports its wind frame circumference side, and the face inboard of keeping out the wind is reverse circular cone table top and the cylinder surface that fuses of top with it; From the spill horn mouth in the face outside of keeping out the wind motor 1 is installed in the cylindrical cavity, motor shaft one end passes the face center hole of keeping out the wind and stretches in the wind frame and be connected with flabellum 2, and wind frame outer upper has individual weather shield 6; Wind shield 3 frames have the hole that is complementary with fastening piece 4; Window bar sheet 5 is tabularly to be connected with wind shield 3 upper frame hinges.During integral installation, at first 4 two outer bolts of fastening piece are fixed on the both sides of window, then, wind shield 3 fast are installed in window by the inner bolt that links to each other with outer bolt.
