In this embodiment, the spout 300 has a thickness of 1.2mm or more, and a precision casting process of stainless steel is employed to ensure resistance to high pressure inside the kettle body 100.

With the above embodiments, the utility model discloses a usage principle and working process are as follows:

the cover 400 is rotated reversely by a predetermined angle to disengage the upper surface of the stopper at the lower end of the cover 400 from the lower surface of the stopper at the upper end of the pot body 100, and the cover 400 is lifted upward to separate the cover 400 from the pot body 100. At this time, the trigger mechanism 600 is not activated, the thimble 610 moves upward under the action of the spring 620, the micro switch 510 is not activated, and the heating element and the power line are in an open circuit state. Then water is injected into the kettle body 100. After the cover 400 is placed above the kettle body 100, the cover 400 is rotated forward by a preset angle, at the moment, the upper surface of the limit block at the lower end of the cover 400 is abutted against the lower surface of the limit block at the upper end of the kettle body 100, and the cover 400 cannot move upwards relative to the kettle body 100; the projection 630 is inserted into the side hole 631, and pushes the thimble 610 downward to trigger the micro switch 510; the power cord is connected, the heating assembly is powered on, and the electric heating device 500 provides heat to start boiling water.

With the rise of the temperature, the steam in the kettle body 100 is discharged from the floater 420 and the spout 300, when the water is boiled to the local boiling point, the air pressure in the kettle is larger than the external air pressure, the floater 420 moves upwards under the push of the air, and the mounting hole is blocked; the innermost swirl ring 310 effectively delays water vapor discharge. When the temperature is higher than 102 ℃, the gas is blocked when passing through the vortex ring 310, a backflow jacking exhaust one-way valve 320 is formed, and when the gas pressure in the kettle is higher than 1.2 atmospheric pressures, the pressure relief valve 410 and the balancing weight 431 are jacked open, so that the gas pressure in the kettle is maintained at 1.2 atmospheric pressures.

When the temperature controller detects that the temperature of water in the kettle reaches 105 ℃, the water boiling is stopped, the quick pressure relief device 430 and the pressure relief valve 410 slowly exhaust, the pressure in the kettle nozzle 300 drops, and the exhaust one-way valve 320 is closed. If the pressure needs to be quickly relieved, the trigger 434 is pressed, the prying piece 433 rotates around the hinged shaft to pry up the counter weight 431, the exhaust nozzle 432 quickly relieves the pressure, and the floater 420 falls back along with the reduction of the air pressure in the kettle.

After the float 420 falls back, the kettle can be lifted by the handle 200 to pour water, if the air pressure in the kettle is still high, the exhaust check valve 320 can play a role in protection, the high-pressure air in the spout 300 is delayed by the vortex ring 310 to advance in the water pouring process, the high-pressure air is forced to be exhausted from the exhaust check valve 320, and radioactive eruption in the water pouring process is prevented.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
