The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

Please refer to FIG. 1 at the same time, which is a perspective view of a preferred embodiment of the toy device of the present invention. Figure. The toy device 100 includes a housing 110, a fan 120, a motor 130, a motor drive circuit 140, a vibration trigger circuit (not shown), a control chip MCU, an infrared emission circuit 141, an infrared receiving circuit 142, and a power supply circuit (not shown). The outer casing 110 is generally pumpkin-shaped and includes an upper opening disposed at an upper portion, an outwardly convex side surface disposed therebetween, and a lower opening disposed at a lower portion. The fan 120, the motor 130, and the motor drive circuit 140 are housed in the outer casing 110. The fan 120 is coupled to the motor 130, and the motor 130 is coupled to the motor drive circuit 140. The infrared transmitting circuit 141 and the infrared receiving circuit 142 are disposed adjacent to the motor driving circuit 140 at the lower opening of the casing. The vibration trigger circuit is connected to the control chip MCU.

The motor drive circuit 140 is for driving the motor 130. The infrared transmitting circuit 141 and the infrared receiving circuit 142 are respectively configured to transmit and receive infrared signals under the control of the control chip MCU. The fan 120 is rotated by the motor 130 to draw air from above and is discharged from below to form an upward reaction force. By adjusting the rotation speed of the motor 130, the magnitude of the lift can be changed, and the lift is matched with the toy device. The self-gravity interaction achieves the effect of automatically controlling its repeated rise, fall, and bounce, as shown in Figure 2. The control chip MCU detects the distance between the bottom of the toy device and the object on the ground or below based on the transmitted and received infrared signals, and controls the motor drive circuit 140 to automatically control the rotational speed of the motor 130 according to the above distance.

Please refer to FIG. 3-7, which is a schematic diagram of the circuit structure of each part of the toy device 100 of the present invention. The control chip MCU is shown in Figure 3. The power supply circuit includes a battery BT1. The battery BT1, the motor 130, the infrared transmitting circuit 141, and the infrared receiving circuit 142 are respectively connected to the microcontroller MCU.

The vibration trigger circuit includes a switch SI. The switch SI is a trigger switch for providing a trigger signal to the control chip MCU. After receiving the signal, the control chip MCU turns off the motor drive circuit 140 to stop the motor 130 from rotating. For example, when the toy device 100 is dropped, collided, or the fan is stuck, the switch S1 senses the vibration and disconnects the power circuit, thereby preventing the toy device from being damaged or accidentally injured. When the toy device 100 is working normally, the infrared transmitting circuit 141 emits an infrared signal, and the infrared receiving circuit 142 receives the infrared signal emitted by the infrared transmitting circuit 141, thereby realizing the distance detection of the toy device 100 from the ground or the object below. The above detection is performed by the control chip MCU in the motor drive circuit 140. When a small distance is set from the ground or the object, the motor drive circuit 140 controls the rotation speed of the motor 130 to increase, so that the air flow is accelerated and the lift is increased, and the toy device 100 forms a bouncing effect.

In the present embodiment, the motor drive circuit 140 of the toy device 100 can also adjust the rotational speed of the motor 130 according to the voltage of the battery BT1 to provide suitable lift. The battery BT1, the motor drive circuit 140, and the corresponding circuit board are disposed at a lower portion of the toy device 100 for controlling the center of gravity of the toy device 100 so as not to be reversed. The upper opening of the toy device 100 is small, and the lower opening is large. The motor 130, the motor driving circuit 140 and the power circuit housed in the outer casing 110 have a conical shape with a conical tip upward. Under the action of the fan rotation, air enters from the upper opening and flows out from the lower opening around the motor drive circuit 140.

The toy device 100 of the present invention comprises the fan 120, the motor 130, the motor drive circuit 140, the infrared transmitting circuit 141, the infrared receiving circuit 142, the control chip MCU, the vibration trigger circuit and the power supply circuit, capable of transmitting and receiving infrared signals and detecting the distance therefrom. The distance of the ground or object, thereby automatically increasing the rotational speed of the fan 120 as it approaches the ground or object, causing the toy device 100 to rise. When moving away from the ground or an object, the speed of the fan 120 is reduced, which in turn slows the rise and moves downward. In addition, a switch S1 is further included, which can automatically disconnect the power supply when the toy device is magnetically impacted, thereby effectively protecting the toy device from damage and accidentally injuring others.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention. within.
