Description

Technical Field

[0002] With the continuous expansion of the leisure and entertainment field, nature-based entertainment has become one of the choices for most people, and hunting in the wild has also become one of the activities chosen by many. Usually, hunting requires bait to lure the prey, and bait ducks have become the choice for most people.

[0003] In the field of outdoor leisure products, swimming-style electric ducks, compared to traditional swimming-style electric ducks, simulate a duck diving for food in the water while swimming, more vividly recreating the image of a duck in the water. Utility model patent CN 119113535 A discloses a swimming-style electric duck that uses a water outlet pipe to spray water backward, creating thrust that impacts a buffer column inside the pipe, causing it to move backward. A traction line connecting the duck's head to the buffer column pulls the duck's head to nod, realistically simulating the activity of a real duck. Utility model patent CN221788120 U discloses a swimming-style electric duck that uses an intermittent working mode to realistically simulate the activity of a duck, offering high ornamental value and attracting real ducks to the water for easy capture. However, current simulated ducks diving and feeding are generally performed individually or in pairs simultaneously, and their complex structures and high requirements for the waterproof performance of the motor result in high costs, difficult production, and short lifespans.
