[0004] For the above reasons, it is necessary to improve the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an electric kettle with a plug rod structure to solve the defect that when the ventilation cover of the existing sprayer is overturned, inverted or tilted, the internal liquid is easy to overflow through the ventilation cover, resulting in waste.

[0006] To solve the above technical problems, the utility model provides the following technical solution: an electric kettle with a plug rod structure, including a kettle body and an electric nozzle arranged on the kettle body. The electric nozzle includes a nozzle seat. One side of the nozzle seat protrudes with a nozzle, and the other side of the nozzle seat protrudes with a handle. It also includes a liquid inlet pipe arranged on the liquid inlet channel communicating with the nozzle. A push button that can be pushed is arranged on the handle, and an electric pump for pressurizing the kettle body is arranged in the nozzle seat. It is characterized in that: a plug rod cavity communicating with the liquid inlet channel is formed on the nozzle seat, and a plug rod is movably arranged in the plug rod cavity. Through the movement of the plug rod in the plug rod cavity, the liquid inlet channel communicating between the nozzle and the liquid inlet pipe can be closed or opened;

A push button 6 that can be pushed is arranged on the handle 4, and an electric pump 7 for pressurizing the kettle body 1 is arranged in the nozzle seat 20.

[0028] A plug rod cavity 101 communicating with the liquid inlet channel 100 is formed on the nozzle seat 20. A plug rod 8 is movably arranged in the plug rod cavity 101. By the movement of the plug rod 8 in the plug rod cavity 101, the liquid inlet channel 100 communicating between the nozzle 3 and the liquid inlet pipe 5 can be closed or opened.

[0029] A trigger switch 9 is arranged on the electric nozzle. Specifically, a groove 40 is arranged at a position adjacent to the connection between the handle 4 and the nozzle seat 20. The trigger switch 9 is arranged in the groove 40. The trigger switch 9 is electrically connected to the electric pump 7. The lower surface of the push button 6 protrudes with a first contact part 61 and a second contact part 62. The position of the first contact part 61 corresponds to the trigger switch 9, and the position of the second contact part 62 corresponds to the plug rod 8. The push button 6 has a first gear position, a second gear position, and a third gear position, and can be switched between the above three gear positions:

[0030] When the push button 6 is in the first gear position, the first contact portion 61 is away from the trigger portion of the trigger switch 9, and the trigger switch is not triggered. The second contact portion 61 is away from the plug rod 8, so that the plug rod 8 closes the liquid inlet passage 100 communicating between the nozzle 3 and the liquid inlet pipe. At this time, the entire electric sprayer is in the shutdown state;

[0031] When the push button 6 is in the second gear position, the first contact portion 61 presses against the trigger portion of the trigger switch 9, and the trigger switch is triggered, thereby turning on the electric pump 7 to pressurize the kettle body 1. And the second contact portion 62 still remains in a position away from the plug rod 8, that is, the plug rod 8 is in a position where the liquid inlet passage 100 communicating between the nozzle 3 and the liquid inlet pipe is closed. At this time, the entire electric sprayer is in the air pressurization state;

[0032] When the push button 6 is in the third gear position, the first contact portion 61 still presses against the trigger portion of the trigger switch 9, and the second contact portion 62 presses against the plug rod 8, causing the plug rod 8 to move downward to open the liquid inlet passage 100 communicating between the nozzle 3 and the liquid inlet pipe; At this time, the entire electric sprayer is in the state of both inflating and spraying while pumping air.

[0033] Wherein, in order to prevent the push button 6 from contacting the main body portion of the trigger switch 9 when sliding, the position of the push button 6 facing the trigger switch 9 is provided with a receiving cavity 60.
