Claim 0:
1. A meteor projection structure, comprising at least one polygonal reflecting wheel (1), at least one laser device (2), at least one light-permeable sheet (3) and at least one motor (4), and a control unit electrically connected with the laser device (2) and the motor (4);
wherein the polygonal reflecting wheel (1) comprises a hexagonal prism having two hexagonal faces and six side faces, the six side faces comprising six rectangular faces perpendicular to the two hexagonal faces; and at least one of the six side surfaces is provided with a reflecting surface, a light emitted by the laser device (2) toward the polygonal reflecting wheel (1) is first reflected by the reflecting surface, and then emitted by the light-permeable sheet (3), wherein the light-permeable sheet (3) intersects with an emergent light path; the motor (4) is connected with the polygonal reflecting wheel (1) through a transmission mechanism (5);
wherein a vertical position of the laser device (2) is located between a center of the polygonal reflecting wheel (1) and the reflecting surface; and the vertical position of the laser device (2) is located at a center of a radius of the polygonal reflecting wheel (1);
wherein the light-permeable sheet (3) is a grating sheet, and the grating sheet is provided with light-permeable textures; the textures are linear grooves moving along the light path; and the quantity of the linear grooves are multiple;
wherein one end of the transmission mechanism is connected with the motor (4), and the other end of the transmission mechanism (4) is connected with the polygonal reflecting wheel (1); and
wherein the motor and transmission mechanism are disposed on the same side of one of the two hexagonal faces; the motor (4) drives the polygonal reflecting wheel (1) to rotate so that when the light emitted by the laser device reflects off the rotating polygonal reflecting wheel, the corresponding light will continually change its position with the movement of the reflecting surface, and will be emitted through the light-permeable sheet.
