Specifically, the housing 10 includes an upper cover 11 and a lower cover 12, which are fastened and easy to operation and conducive to subsequent maintenance. The upper cover 11 and the lower cover 12 are enclosed to form the accommodation space 101, the upper cover 11 and the lower cover 12 are hollow out to form the holes 102 communicated with the accommodation space 101.

[0027] The bracket 20 is mounted in the accommodation space 101, the bracket 20 provides a shaft 81. A central of the shaft 81 coincides with a center of the housing 10, which avoids eccentricity and interference to the self-stability of the boomerang, and ensures that the flight trajectory of the boomerang can be judged. Specifically, in the embodiment, the bracket 20 includes a lower seat 21, a motor cover 22, an upper seat 23 and a pressure cover 24. The motor cover 22 is fixed with the lower seat 21 to enclose a first cavity 201, the upper seat 23 is fixed on the motor cover 22, and the pressure cover 24 is fixed with the upper seat 23 to enclose a second cavity 202. And, a periphery of the lower seat 21 provides a plurality of the first rotating blades 203 spaced around a periphery of the shaft 81, there are hollow areas 204 between the adjacent rotating blades 203. The first rotating blades 203 are arranged in a curved shape along the periphery of the shaft 81, and the plurality of the first rotating blades 203 are curved in the same direction so that the first rotating blades 203 rotate to produce a large downward wind; and, the bracket 20 has a rack 25 with one end fixed with the pressure cover 24, both ends of the shaft 81 are fixedly connected with an upper side and a bottom side of the housing 10, respectively, and both ends of the rack 25 are sleeved at both ends of the shaft 81, respectively.

[0028] The paddle 30 is located in the accommodating space 101 and rotatably disposed on the shaft 81; the paddle 30 provides a plurality of the second rotating blades 31 along an upper and down direction of the main housing 10, the second rotating blades 31 and the first rotating blades 203 are arranged obliquely, respectively, and the inclined direction of the first rotating blades 203 and those of the second rotating blades 31 are opposite.

[0029] The main control board 40, the power supply 50, the motor 60 and the lamp strip 70 are mounted on the bracket 20. The power supply 50, the motor 60 and the lamp strip 70 are electrically connected to the main control board 40 the motor 60 drives the shaft 81 to rotate.

[0030] In the embodiment, the main control board 40 provides a main control chip 41 connected with an acceleration sensor 42 feedback signal to the main control chip 41, the main control chip 41 controls the motor 60 to rotate. And, the power supply 50 and the motor 60 are arranged in the first cavity 201, the main control board 40 is fixed in the second cavity 202, and the shaft 81 passes the first cavity 201 and the second cavity 202. And, the shaft 81 provides a drive gear 83, the paddle 30 is fixedly sleeved with the drive gear 82, an output shaft 61 of the motor 60 is fixed with an active gear 83 engaged with the drive gear 82. Additionally, the lamp strip 701 is fixed on an outer surface of the rack 25. The outer surface of the rack 25 is provided with a fixing groove 205, the lamp strip 70 is soft LED lamp strip fixed in the fixing groove 205.

[0031] The principle of the invention is as follows: In works, the boomerang is started, the power supply 50 powers the motor 60 and the strip 70 through the main control board 40. The motor 60 works to drive the paddle 30 to rotate, the rotating direction of the paddle 30 is contrast with the bracket 20 so that the torsion generated by relative rotation between the bracket 20 and the paddle 30 counteracts each other and generates downward wind, thereby causing the lift of the boomerang, the lamp strip 70 is illuminated to light. After the boomerang is thrown out, it stably flies in the air according, to the thrown angle, with the works of the external force, the boomerang flies a distance towards the thrown direction, then because of the gyro effect producing by the rotation of the bracket, the flight angle of the boomerang remains constant and the boomerang continues to flying in the direction of that angle. That is to say; users can preset the throwing angle of the boomerang, thereby obtaining different flight trajectories. In the flight process, the boomerang will generate cool lighting effect.

[0032] The design focus of the invention is concerned: The boomerang is designed as a ball shape and to use the motor to drive the paddle to rotate; when the boomerang is thrown out, it stably flies in the air at the thrown angle. Under the works of the external force thrown, the boomerang flies a distance in the direction thrown, then because of the gyro effect producing by the rotation of the bracket and the paddle, the flight angle of the boomerang remains constant and the boomerang continues to flying in the direction of that angle. Users can preset the throwing angles of the boomerang, thereby obtaining different flight trajectories, no remote control is required to control the flight trajectories. Users, can throw the boomerang according to the presetting angles to obtain the presetting flight trajectories, and the boomerang can achieve to stably and instantly fly in the air. The boomerang is simple in structure and easy to operate. At the same time, with the lamp strip, the boomerang can produce a cool lighting effect.

[0033] The technical principles of the invention are described above in combination with specific embodiments. These descriptions are only intended to explain the principles of the invention, and cannot be interpreted in any way as limiting the protection scope of the invention. Based on the interpretation herein, those skilled in the art may associate of other specific embodiments of the invention without any creative labor, all of which will fall within the protection scope of the invention.
