[0080] Working principle of this embodiment

[0081] 1) When the knob 7 is turned to the first working point (aligned with the first positioning hole 64), the kettle lid is in a normally open state. At this time, the working surface 532 of the adjustment seat 5 presses the adjustment rod 4 downward, so that the working valve core 8 descends and the safety valve core 9 rises, creating a drainage channel connecting the outside world with the inside of the kettle. In this state, the gas in the kettle can be discharged to the outside world through the drainage channel, realizing the exhaust function. After the exhaust is completed, the kettle is tilted toward the pouring spout 13. Under the action of gravity, the liquid in the kettle descends through the working valve core 8, and the drainage channel created by the rising safety valve core 9 and the connecting channel set by the fixed seat 3 flow out through the spout.

[0082] 2) When the knob 7 is rotated to the second working point (aligned with the second positioning hole 65), the kettle cover is in the working state. At this time, the working surface 532 of the adjustment seat 5 is separated from the pressure regulating rod, and the safety valve core 9 is pressed downward under the action of the first spring 93 to seal the channel (the second sleeve 32 and the second exhaust hole 22) set below the safety valve core 9, and at the same time drive the pressure regulating rod to press downward, so that the pressure regulating rod near the safety valve end is tilted upward; at this time, the kettle is heated, and as the temperature rises, the gas in the kettle lifts the working valve core 8 to seal the gas and the external drainage channel, forming a sealed space in the kettle, and the pressure in the kettle rises rapidly. When the pressure in the kettle reaches the set value, the air pressure lifts the safety valve core 9, and the channel (the second sleeve 32 and the second exhaust hole 22) set below the safety valve core 9 is opened, and the gas is discharged into the exhaust channel to achieve pressure relief. After the pressure in the kettle drops, under the action of the first spring 93, the channel (the second sleeve 32 and the second exhaust hole 22) set below the safety valve core 9 is sealed again, so that the pressure in the kettle is maintained stable.

[0083] This embodiment also has the following advantages:

[0084] 1) Dual valve coordinated control technology

[0085] In this embodiment, the synchronous lifting and lowering of the working valve core 8 and the safety valve core 9 are controlled by the adjusting rod 4, so as to realize the synchronous opening and closing of the first exhaust hole 21 and the second exhaust hole 22, thereby ensuring the precise switching between the pressure increasing and pressure maintaining and the pressure relief and drainage functions.

[0086] The risk of single valve core failure can be avoided and the reliability of pressure control can be improved. The operation logic is simplified through linkage design, and the user only needs to rotate knob 7 to complete the function switching (such as increasing pressure when boiling water and releasing pressure when pouring water).

[0087] 2) Modular sealing and drainage channel design

[0088] The first exhaust hole 21, the second exhaust hole 22, the connecting pipe 34 and the drain port 33 form an integrated drain channel, and the coordinated action of the working valve core 8 and the safety valve core 9 realizes the directional discharge of gas and water.

[0089] Pressure boost and pressure maintenance stage: the double exhaust holes are closed to increase the pressure inside the kettle to speed up the boiling efficiency;

[0090] Pressure relief and drainage stage: the dual exhaust holes are opened synchronously, the gas is discharged through the drainage channel, and when pouring water, the water flows through the drainage port 33 and flows out from the pouring spout 13 smoothly, avoiding the risk of steam splashing.

[0091] 3) Multiple sealing protection mechanisms**

[0092] The valve disc 81 of the working valve core 8 is provided with a first sealing ring 84, the safety valve core 9 seals the mounting hole 321 through a gasket 94, and a second sealing ring 25 is provided on the periphery of the base 2, forming a three-level sealing structure, which can prevent high-temperature steam leakage, improve the pressure stability in the kettle, and reduce the risk of scalding.

[0093] 4) Anti-slip structure design

[0094] The working valve core 8 is limited by the cooperation of the first protruding ring 351 and the second protruding ring 83, and the safety valve core 9 is clamped by the U-shaped fork 43 and the fourth protruding ring 95, so as to ensure the stability of the valve core movement trajectory, avoid the valve core from falling off due to pressure fluctuation or vibration, and prolong the service life.

[0095] 5) One-touch operation and status feedback

[0096] The adjustment module drives the inclined surface and the lever mechanism (adjustment rod 4) through the knob 7, and the adjustment rod 4 is linked to press the working valve core 8 and fork the safety valve core 9. Combined with the gear design of the spring column 73 and the positioning hole, it provides a clear operating feel and status feedback. The user can intuitively switch between the "boost" and "decompression" modes by rotating the knob 7, which is convenient to operate and reduces the possibility of misoperation.

[0097] 6) Convenient opening and closing design of the snap-on module

[0098] The double clamping blocks 10 are symmetrically arranged, and the guide column 102 and the annular retaining ring 11 are quickly engaged / released by the elastic reset of the second spring 101. The cover can be opened by pressing with one hand, and the spring force automatically locks when closed, taking into account both sealing and operational convenience.

[0099] 7) Spoiler 341 condensation reflux technology

[0100] A spoiler 341 is provided in the connecting pipe 34 to extend the steam flow path and promote condensation, thereby reducing the heat waste and scalding risk caused by direct discharge of high-temperature steam and improving energy utilization.

[0101] 8) Gravity valve core adaptive adjustment

[0102] The gravity valve core body of the safety valve core 9 ensures that the second exhaust hole 22 is automatically closed in a non-dumping state through the dual effects of the preload force of the first spring 93 and gravity.

[0103] 9) Strengthen structural stability

[0104] The first valve column 82 is connected to the valve disc 81 through the rib plate 85, and the bending arm design of the regulating rod 4 enhances the anti-deformation ability, which can improve the structural strength of key components under high pressure environment and avoid fatigue damage caused by long-term use.

Any equivalent implementation or modification that does not deviate from the present invention should be included in the patent scope of this case.
