Abstract

The utility model discloses a toy fish which comprises a full-sealed fish-shaped casing and a fish tail connected on the casing. A circuit board, a battery and a driving device for driving the fish tail to swing are arranged in the casing. The driving device comprises a coil support and a rock shaft, wherein a coil is arranged in the coil support, a fixed magnet is respectively arranged on two sides of the coil, the polarities of the two magnets facing the coil are identical, the fish tail is arranged on the rock shaft, two ends of the circuit board are connected with conductive rubber strips, a cavity is correspondingly arranged on the casing, and the conductive rubber strips penetrate through the cavity to extend out of the casing. When the toy fish is placed in water, the conductive rubber strips and water can form a conductive circuit to trigger a main control chip on the circuit board to output alternating current, the coil can be charged to generate magnetic fields and manually act with the magnets to generate suction force/push force, the coil support can drive the rock shaft and the magnets to move, and the rock shaft can drive the fish tail to horizontally swing to one side. When the direction of the current changes continuously, the fish tail can swing to two sides continuously, and the toy fish can swims in water continuously.

Description

A kind of toy fish

Technical field

The utility model relates to the toy field, especially a kind of toy fish.

Background technology

Along with the progress in epoch and the development of science and technology, people are more and more higher to the requirement of toy, along with the external form of electronic toy is more and smaller and more exquisite, children also more and more tend to pursue the mini electronic toy of small-power, for example can imitate under water the toy fish of fish swimming.

Toy fish on the market, mainly formed by fish shape shell and fish tail, be provided with motor in the shell, drive swing mechanism by motor and drive fish tail swing, thus the swing effect of imitation fish trip, and this type toy fish is owing to having used motor, profile is huge, complicated integral structure, and the growth cost is higher, is difficult to satisfy consumers in general's needs.

The utility model content

The purpose of this utility model provides a kind of simple in structure, powerful toy fish.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of toy fish, hermetic fish shape shell body and the fish tail that is connected on the shell body have been comprised, be provided with circuit board in the shell body, battery and the drive unit that drives fish tail swing, described drive unit comprises the coil brace of being located at the shell body rear side and the swinging shaft that is connected with coil brace, be provided with the coil that is connected with circuit board in the coil brace, respectively there is a fixedly magnetite coil both sides, two magnetites are identical towards the magnetic force polarity of coil, described fish tail is located on the swinging shaft, described circuit board two ends are connected with conductive rubber strip, correspondence offers die cavity on the shell body, and described conductive rubber strip wears and extends to outside the shell body from die cavity.

Wherein, described shell body bottom is connected with battery cover by screw, and the battery cover both sides are provided with abdomeinal fin.

In addition, described shell body is comprised of left side housing and right side housing, and described two magnetites are separately fixed on left side housing and the right side housing.

In addition, described shell body rear side is provided with the guide ring of supporting swinging shaft.

In addition, described circuit board comprises MCU and the trigger module that is connected with MCU, power module and action output module.

The beneficial effects of the utility model are: conductive rubber strip and water form the galvanic circle after toy fish is put into water, with the main control chip on the circuits for triggering plate, the output alternating current, make coil charges generation magnetic field and produce suction/thrust with the magnetite interaction, coil brace drives swinging shaft and magnetite produces quite mobile, swinging shaft drives fish tail toward a side horizontal hunting, when the sense of current constantly changes, fish tail does not stop to wave toward both sides, and this moment, toy fish did not just stop to move about in water, and this toy fish adopts button cell as power supply, need not motor, therefore volume is small and exquisite, simple in structure, and is with low cost and playability is high.
