[0002] Centrifugal motion is the object that does uniform circular motion, when the combined external force disappears suddenly or the combined external force is not enough to provide the required centripetal force, will do the motion that gradually far away from the center of circle. The machinery that is made into according to centrifugal motion principle is called centrifugal machinery, for example centrifugal liquid distributor, centrifugal speed changer, centrifugal water pump, centrifugal ball mill etc. are all the principle of utilizing centrifugal motion. But the centrifugal motion in this kind of equipment, generally, it is difficult to observe directly, when helping children to observe centrifugal motion, most are fixed devices, cannot hold the change orientation according to the motion characteristic of centrifugal motion to feel the change rule of centrifugal motion, it is not conducive to deeply understanding centrifugal motion principle, now need a portable handheld device that can directly observe and feel centrifugal motion, satisfy the demand of teaching in a playful way. SUMMARY

[0003] The utility model solves the above-mentioned prior art problems, provides a handheld centrifugal toy, solves the problem that the current traditional centrifugal motion device is fixed and cannot be handheld, portable and directly feel the centrifugal motion.

[0004] The utility model solves the technical scheme that its technical problem adopts: this handheld centrifugal toy, including long handle shape's handle, the handle one end is the handle end of hand and the other end's front end face rotationally connected with the rotating disc, the rotating disc front end face is fixed with the hollow hemispherical structure of centrifugal cover that is arranged concentrically with the rotating disc, the opening of the top center position of centrifugal cover is set up and is taken and is put, the rotating disc rear end face is fixed with the drive motor that is transmission connection with the rotating disc, and the rotating disc is rotationally arranged in parallel with the handle. After setting like this, the handle end of hand of handheld handle, the article can be put into the centrifugal cover through the opening, the drive motor is used for driving the rotating disc to rotate, and the rotating disc synchronously drives the centrifugal cover to rotate, looks the article whether will fall down to the centrifugal cover opening, connects the motion rule of centrifugal motion, helps children to understand centrifugal motion, and achieves teaching in a playful way.

[0005] As a further improvement of the utility model, the centrifugal cover and the rotating disc are sealingly connected to form a semi-closed centrifugal cover structure with only the opening open. After setting like this, the centrifugal cover can be filled with liquid materials such as water, and the performance of the liquid under centrifugal motion can be observed. The application scenario is more, and the application range is wider.

[0006] As a further improvement of the utility model, the centrifugal cover is a transparent material integrated structure. After setting like this, the centrifugal motion of the object in the centrifugal cover can be directly observed from the outside, and the observation is more clear and simple.

[0007] As further improvement of the utility model, the rotary disc is internally provided with a battery, the battery is connected with a centrifugal switch and an LED lamp through a control circuit, the centrifugal switch is connected with the LED lamp for controlling opening and closing, and the LED lamp is circumferentially arranged on the side end surface of the rotary disc.

[0008] As further improvement of the utility model, a switch for starting and stopping the driving motor is arranged on the rear end surface of the rotary disc, the switch is a rotary stepless adjustment switch, and the switch forms a speed regulating switch for rotatingly adjusting the rotating speed of the driving motor through the control circuit. The switch is used for controlling the starting and stopping of the driving motor, and the switch itself is a stepless adjustment switch structure, and can also be used for adjusting the rotating speed of the driving motor. Thus, the starting and stopping and the speed regulating are unified to one switch structure, and an additional switch is not needed for controlling the starting and stopping and the speed regulating, and the structure is effectively simplified under the condition of ensuring the switch effect.

[0009] The utility model has the advantages of reasonable and compact structure, the article is put into the centrifugal cover through the handle end, the driving motor is started to observe the motion law of the article, the centrifugal motion is directly understood through the transparent centrifugal cover, the whole structure is portable, the use effect is good, the teaching is combined with the fun, and the utility model is suitable for being popularized.
