[0039] With reference to Figures 1 to 13 , the working principle of the toy simulating the sucking action is as follows:

[0040] When the user stretches the toy finger or the nipple of the feeding bottle into the mouth 11, the toy finger or the nipple presses the mouth 11 inward, the inward protruding part of the mouth 11 presses the button 92 inward, the button 92 presses the key 911 on the key circuit board 91, the motor 8 is started, drives the worm 85 to rotate, and the worm 85 drives the lower drive gear 84 to rotate through the first double gear 81 and the second double gear 82 in turn. On the one hand, the lower drive gear 84 drives the lower eccentric wheel 61 to eccentric rotate, and then drives the lower connecting rod 71 to stretch and retract, reciprocally pushes and pulls the lower lip of the mouth 11. On the other hand, the lower drive gear 84 drives the upper drive gear 83 to rotate, and the upper drive gear 83 drives the upper eccentric wheel 6 to eccentric rotate, and then drives the upper connecting rod 7 to stretch and retract, reciprocally pushes and pulls the upper lip of the mouth 11. Since the rotating direction of the lower drive gear 84 is opposite to that of the upper drive gear 83, the rotating direction of the upper eccentric wheel 6 is opposite to that of the lower eccentric wheel 61, so the pushing and pulling actions of the lower connecting rod 71 and the upper connecting rod 7 are opposite (for example, when the upper connecting rod 7 pushes forward, the lower connecting rod 71 pulls backward), thereby realizing the sucking action of the mouth 11. In this process, since the lower rotating shaft 841 rotates with the lower drive gear 84, the lower rotating shaft 841 drives the rotating part 842 to rotate, the rotating contact 8421 on the rotating part 842 rotates in the adjusting hole of the potentiometer 94, thereby determining the angle or position of the lower rotating shaft 841. At the same time, the contact block 8422 on the rotating part 842 presses the contact of the micro switch 931, triggers the switch action, makes the internal circuit of the switch close or open, thereby generating an electric signal. The electric signal can be used for counting to record the number of rotations of the lower drive gear 84.

[0041] When the user taps the area corresponding to the conductive copper foil 3 on the toy belly (the conductive copper foil 3 serves as a sensor to perceive the tapping action), the conductive copper foil 3 will deform. This deformation causes a certain form of physical or electrical change in the connection (through the cable 31) between the conductive copper foil 3 and the main circuit board 9, thereby generating an electric signal. The electric signal is received and processed by the main circuit board 9, triggering the horn 4 to emit sound.

[0042] The toy for simulating sucking action of the utility model, utilize two eccentric wheels in the head of the toy body 1 eccentric rotate up and down, drive two connecting rods stretch and retract movement, and then act on the corresponding position of the mouth 11 made of flexible material, convert the rotating movement of the eccentric wheel into the opening and closing action of the mouth 11, make the toy realize higher fidelity in sucking action simulation, and add rich interesting, bring novel and pleasant experience for the user.

[0043] The simulation sucking action toy is not only highly simulated in appearance and touch feeling, but more importantly, a eccentric wheel-link driving mechanism in the interior successfully simulates a real sucking action (such as: sucking milk, water or other liquid), and provides a novel and educational interactive experience for the baby. In addition, the structural design of the toy is easy to adjust and maintain, and provides convenience for subsequent product upgrading and function expansion, indicating that the toy has broad application prospect and market potential in the field of parent-child interactive toys.

[0044] The above disclosed is only the preferred embodiment of the utility model, and cannot be used to limit the protection scope of the utility model, therefore, equivalent changes made in the patent application range of the utility model still belong to the range covered by the utility model.
