Magnetomotive light-emitting toy jumping ball

Abstract

The invention discloses a magnetomotive light-emitting toy jumping ball. The magnetomotive light-emitting toy jumping ball comprises a sleeve ring and a ball body fixedly connected to the side wall ofthe sleeve ring through a connecting rod, wherein an annular groove is formed in the side wall of the ball body, a rotating sleeve is mounted at the inner side of the annular groove, blades are welded to the rotating sleeve at equal intervals, one of the blades is made of a magnetic material, and an arc-shaped cavity is formed in the side wall of the ball body. The blades rotate uninterruptedly,a magnetic block moves in the arc-shaped cavity in a reciprocating manner, during the uninterrupted moving process of the magnetic block, air in the arc-shaped cavity enters an annular cavity throughan air guide cavity and then is sprayed out from air outlet holes, and then heat dissipation is carried out on the leg and the sleeve ring; cooling liquid in the arc-shaped cavity is pressed into a spiral condensing cavity through a liquid guide cavity, and then the heat dissipation of the sleeve ring is accelerated; and during the process that the magnetic block moves in the arc-shaped cavity, induction current is formed in a spiral coil by utilizing the principle that the magnetic block cuts magnetic induction lines, further, a color lamp group emits light, and therefore, the playability ofthe jumping ball is increased.

Description

technical field [0001] The invention relates to the technical field of toys, in particular to a magnetic light-emitting toy bouncing ball. Background technique [0002] Jumping ball is a kind of toy suitable for children and adults. It consists of a ring on the calf and a sphere fixedly connected to the side wall of the ring through a connecting rod. The user puts the ring on the calf , By swinging the calf, the ball rotates along the axis of the ring, and the other leg avoids the ball to complete the play, so as to achieve the effect of weight loss and fitness, and can train children's coordination and reaction ability. [0003] However, after the jumping ball is used for a period of time, especially in summer, the calf is exposed. Due to the long-term friction between the force-generating part of the calf and the collar, the temperature of the force-generating part will increase, and the continuously rotating collar will always When in contact with the user's calf, the he...

Problems solved by technology

[0003] However, after the jumping ball is used for a period of time, especially in summer, the calf is exposed. Due to the long-term friction between the force-generating part of the calf and the collar, the temperature of the force-generating part will increase, and the continuously rotating collar will always When in contact with the user's calf, the heat cannot be dissipated quickly, causing the user to feel uncomfortable, and even causing the user's skin to be red, swollen and broken. In order to increase the fun of the existing bouncing ball, light is usually set in the toy Colored lights are used to attract children. The electronically controlled light-emitting color lights have a single light-emitting form, and the lighting-related electronic control components are easily broken during play, and the service life is short. When the light-emitting color lights no longer glow, the toy is no longer Re-attract children, easy to be abandoned by children
