Specifically, the ratchet mechanism comprises a ratchet 6 keyed with the connecting shaft 43 and limiting blocks 62 fixed on the outer wall of the second ball valve 44, the limiting blocks 62 are circumferentially and equidistantly arrayed around the ratchet 6, a ratchet rod 61 matched with the limiting blocks 62 is hinged on the ratchet 6, and the ratchet rod 61 can rotate 180 ° around the ratchet 6.
Specifically, an electric heating rod 22 is arranged at the bottom of the kettle body 2, and a power supply 13 matched with the electric heating rod 22 is arranged at the upper end of the base 1; when the kettle body 2 is placed on the base 1, the power supply 13 is in contact with the electric heating rod 22, so that the electric heating rod 22 starts to work.
Specifically, a temperature sensor 25 capable of controlling the power supply 13 is arranged in the kettle body 2, and when the temperature sensor 25 detects that the temperature in the kettle body 2 reaches a certain value, the power supply 13 can be controlled to stop working.
Specifically, an input device 26 capable of controlling the motor 51 to work is arranged on the outer wall of the kettle body 2, the weight of water required to be used is input through the input device 26, and when the pressure sensor on the base 1 detects that the weight of the water in the kettle body 2 is reached, the motor 51 is controlled to rotate, so that the second ball valve 44 is driven to close, and water inlet is stopped.
Specifically, a water outlet is arranged at the upper end of the kettle body 2, and a baffle 23 capable of closing the water outlet is hinged on the kettle body 2 through a torsion spring.

When boiling, the desired weight of water is input at the input 26 and the kettle body 2 is then placed on the base 1 with the inlet valve 21 aligned with the inlet conduit 12. In the process that the kettle body 2 is placed on the base 1, the kettle body 2 presses the trigger diagonal rod 3 downwards, so that the trigger diagonal rod 3 moves downwards, the first gear 31 is driven to rotate, and the reset diagonal rod 4 moves towards the direction close to the second ball valve 44. The first gear 31 drives the second gear 32 to rotate, so as to drive the first ball valve 34 to rotate, the first ball valve 34 rotates to communicate the water pipe 11 with the water inlet pipe 12, and water enters the kettle body 2 from the water pipe 11. The sliding gear 42 moves under the action of the reset inclined rod 4 so as to be meshed with the linkage gear 33, and the connecting shaft 43 is connected with the second ball valve 44 through the ratchet structure, so that the sliding gear 42 cannot drive the second ball valve 44 to rotate when driving the connecting shaft 43 to rotate, and water cannot be blocked from entering the kettle body 2. The electric heating bar 22 is contacted with the power supply 13 to start working.
When the pressure sensor in the base 1 detects that the water in the kettle body 2 reaches a set weight, a signal is sent to drive the motor 51 to drive the cam 5 to rotate. Under the drive of the driven wheel 52 and the reset gear 53, the second ball valve 44 is rotated to be closed, and water feeding is stopped. When the water in the kettle body 2 boils, the temperature sensor 25 sends a signal to stop the power supply 13 and stop heating.
The kettle body 2 is lifted away from the base 1, the water inlet valve 21 is a one-way valve, and water can only enter but can not flow out. The reset tilting rod 4 moves away from the second ball valve 44 by the spring 41 and moves the trigger tilting rod 3 upward by the repulsive force of the first magnet 14 and the second magnet 35. The triggering diagonal rod 3 drives the first gear 31 to rotate reversely, and drives the first ball valve 34 to rotate and close. The interlocking gear 33 rotates the slide gear 42 in the reverse direction until the slide gear 42 is disengaged from the interlocking gear 33. When the connecting shaft 43 is driven by the sliding gear 42 to rotate, the ratchet rod 61 pushes the limiting block 62, so that the second ball valve 44 is rotated to open and is communicated with the water pipe 11, and preparation is made for the next water inlet.
When water is poured, the water in the kettle body 2 pushes the baffle 23 away.
