Description
Technical Field
[0001] This utility model relates to the field of coral reef ecosystem restoration technology, and in particular to a multifunctional pressure kettle. Background Technology
[0002] Existing multi-functional pressure kettles often have only a single pressure relief valve, which cannot effectively release air and maintain pressure simultaneously. Other products typically use independently set air relief valves and safety pressure relief devices to achieve air release and pressure control functions, which have drawbacks such as cumbersome operation steps and redundant structure. When releasing air or pouring liquid, manual switching of modes is required, which can easily lead to seal failure due to misoperation. Furthermore, the need to manually operate multiple parts can cause inconvenience or safety hazards. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional pressure kettle.
[0004] This utility model is achieved through the following technical solution: a multifunctional pressure kettle, including a kettle body and a kettle lid. The kettle body has a pouring spout and a ring retaining ring at the spout. The kettle lid includes a base, a locking module, a valve core module, and an adjustment module. The locking module is installed on the base and is engaged or disengaged by pressing the ring retaining ring. The base has a first vent hole and a second vent hole. The valve core module includes a working valve core, a safety valve core, and a fixing seat. The fixing seat has a first sleeve for installing the working valve core and a second sleeve for installing the safety valve core. An adjustment module is mounted on the fixed base. The adjustment module is equipped with an adjustment rod for controlling the working valve core and the safety valve core to achieve the function of one valve core rising and the other valve core falling. A drain port and a connecting pipe connecting the first sleeve and the second sleeve are provided between the base and the fixed base. Controlled by the adjustment rod, the working valve core opens or closes the first vent hole, and the safety valve core opens or closes the second vent hole. The first vent hole and the second vent hole open and close synchronously. The first vent hole, the second vent hole, the connecting pipe and the drain port form a drainage channel, and the drain port is aligned with the drain spout.
[0005] The first and second vents open or close simultaneously. When both vents are open, they form a drainage channel together with the connecting pipe and drain outlet. When the multi-functional pressure kettle is not tilted, gas can flow out through the drainage channel. When the kettle is tilted, water flows out of the kettle through the drain outlet and pouring spout. The locking module can fasten or loosen the kettle body. The working valve core controls the opening and closing of the first vent, and the safety valve core controls the opening and closing of the second vent. The adjusting module's adjusting rod controls the working valve core and safety valve core, allowing one valve core to rise and the other to fall, thus forcing the two vents to open or close. When both vents are closed, the drainage channel is closed, achieving a pressure-boosting and pressure-maintaining function, increasing the pressure inside the kettle, which is beneficial for boiling water. When both vents are closed, the drainage channel can release gas, achieving a pressure-relieving function. When water needs to be poured out, the kettle body is tilted, and water can flow out of the kettle through the drainage channel. This structure allows for one-button control of venting and pressure relief. The locking module is used to control the opening and closing of the kettle lid and body. The connecting pipe is designed to direct water vapor from the second vent to the first vent and into the drain outlet.
[0006] The first sleeve contains a first guide cylinder, the lower end of which communicates with the first sleeve, and its upper opening penetrates the upper side of the fixed base. The lower end of the first guide cylinder is folded inward to form a first raised ring. The working valve core includes a valve disc and a first valve post fixed to its center. A second raised ring is provided around the outer periphery of the upper section of the first valve post. The upper section of the first valve post is located inside the first guide cylinder and can slide along it. The second raised ring moves close to or away from the first raised ring as the first valve post moves. The valve disc is located below the base and closes or opens the first vent hole as the first valve post moves. The upper end of the first valve post contacts the end of the adjusting rod. The cooperation between the second raised ring and the first raised ring prevents the working valve core from falling off and restricts its range of motion. The valve disc is used to close or open the first vent hole, thereby realizing the function of venting, depressurizing, or draining water.
[0007] The second sleeve has a mounting hole at its top; the valve core module also includes a first spring and a washer; the safety valve core includes a gravity valve core body at the bottom and a second valve post at the top, the lower part of the gravity valve core body protrudes outward to form a third protruding ring, and the diameter of the second valve post is smaller than the diameter of the gravity valve core body; the second valve post passes through the mounting hole and can slide along it, the first spring is sleeved on the outer periphery of the safety valve core, its lower end abutting against the third protruding ring, and its upper end abutting against the top wall of the second sleeve; the washer is sleeved on the outer periphery of the second valve post, its lower side abutting against the top of the gravity valve core body; the lower end of the gravity valve core body can movably close or open the second vent hole. The first spring has elasticity and tends to push the gravity valve core body towards the second vent hole, ensuring the function of closing the second vent hole; the washer is used to form a seal around the mounting hole to prevent moisture from overflowing from the mounting hole and contaminating the inside of the lid.
[0008] The adjustment module also includes a knob, a panel, an adjustment base, a screw, and a rotating shaft. The screw passes through the adjustment base and the panel in sequence and is then tightened into the knob. The knob has a locking hole, and the upper side of the adjustment base has a boss with a pair of protrusions on one pair of opposite sides, one of which extends downward to form a locking element. The boss is fitted into the locking hole, and the adjustment base rotates with the knob through the engagement of the boss and the locking hole. The side wall of the locking element is cut to form a first inclined surface. When the adjustment base rotates counterclockwise, the first inclined surface is located on the front side of the locking element, and the plane below the boss that is in contact with the first inclined surface forms a working surface. The lower side of the panel has a connector with a first rotating shaft hole. The middle section of the adjustment rod is cut downward on both sides to form a second inclined surface. One end of the adjustment rod has a pressing part at its lower part, and the other end is bent downward and coiled thereon. The end forms a U-shaped fork, and the transition area between the bend and the middle section of the adjusting rod arches upward to form a bent arm. A second pivot hole is provided at the bent arm to pass through it. The rotating shaft passes through the second pivot hole and the first pivot hole, hinged to the adjusting rod on the panel. The top of the safety valve core protrudes outward to form a fourth protruding ring. The U-shaped fork is engaged with the outer circumference of the upper section of the safety valve core and located below the fourth protruding ring. The pressing part presses or releases the top of the working valve core as the adjusting rod rotates. The first inclined surface squeezes or releases the second inclined surface as the knob rotates, causing the adjusting rod to sink or float. The U-shaped fork lifts or lowers the fourth protruding ring as the adjusting rod rotates. When the pressing part presses tightly against the top of the working valve core, the working surface of the adjusting seat presses against the upper side of the adjusting rod. The engagement of the boss and the locking hole allows the adjusting seat to rotate synchronously when the knob is rotated. The U-shaped fork is used to lift or lower the safety valve core. The rotating shaft engages with the first and second rotating shaft holes to hinge the adjusting rod to the panel, making the adjusting rod a lever. The lever principle is used to adjust both ends of the lever. When the adjusting seat rotates counterclockwise, the first inclined surface of the locking piece presses against the second inclined surface of the middle section of the adjusting rod, forcing the adjusting rod on the side where the pressing part is located to move down. When the pressing part presses tightly against the top of the working valve core, the working surface of the adjusting seat locking piece presses against the upper side of the adjusting rod, forming a stable working state.
[0009] The adjustment module also includes a spring post; the panel has a first central hole, a first positioning hole and a second positioning hole on its upper side, and a positioning post and a limiting block on its lower side; there is a pair of positioning posts, located on both sides of the panel; there is a pair of limiting blocks, symmetrically distributed on both sides of the panel, symmetrically distributed on the opposite side of the first central hole; there is a pair of connectors, located on both sides of the panel; the knob has a third positioning hole, and the adjustment seat has a second central hole; the screw passes through the second central hole and the first central hole in sequence and is then tightened into the threaded hole in the center of the knob; the spring post is located in the third positioning hole and slides between the first positioning hole and the second positioning hole as the knob rotates, thus being placed into either positioning hole; the panel is clamped between the knob and the adjustment seat, and any of the protrusions is located in the arc-shaped groove formed between the two limiting blocks and can slide in the arc-shaped groove; the middle of the fixing seat has a pair of third sleeves, and the two positioning posts are sleeved in the third sleeves; the two ends of the long axis of the panel are respectively provided with hooks, and the hooks fasten the sides of the fixing seat. The first and second positioning holes allow the spring post to slide within the range of the two holes, which represent the limit positions of the spring post's movement. The engagement of the positioning post with the third sleeve constrains the panel and the fixed base. The limiting block restricts the range of motion of the protrusion. The hooks secure the two ends of the panel to the sides of the fixed base.
[0010] The width of the U-shaped fork opening is smaller than the outer diameter of the fourth protruding ring, which can prevent the safety valve core from disengaging from the control of the U-shaped fork.
[0011] The valve disc has an annular groove, within which a first sealing ring is installed. When the working valve core closes the first vent hole, the upper side of the first sealing ring abuts against the bottom surface of the base surrounding the first vent hole. Several ribs are evenly distributed around the lower section of the first valve stem, with the lower ends of the ribs connected to the valve disc. The first sealing ring creates a seal between the valve disc and the lower surface of the base surrounding the first vent hole, improving sealing performance. The ribs enhance the stability of the connection between the first valve stem and the valve disc.
[0012] The locking module includes locking blocks and a second spring. Two locking blocks are symmetrically arranged, with the center of the lid as the innermost point. The outer side of each locking block extends outward to form a guide post, and the inner side of each locking block has a limiting component. The base has a second guide cylinder, and the guide post is fitted inside the second guide cylinder and can slide along it. One end of the second spring is locked onto the limiting component of one side of the locking block, and the other end of the second spring is locked onto the limiting component of the other side of the locking block. The upper side of the fixing seat has two downward-facing recesses forming recesses. A limiting groove communicating with the recess is formed on the wall near the center of the fixing seat. The locking block is located in the limiting groove and extends out of the space of the recess. When both hands grip the pair of locking blocks, the guide post releases the annular retaining ring; when the locking blocks are released, the guide post locks the annular retaining ring. The second spring is used to hold the two locking blocks together, ensuring they always protrude outward, causing the guide post to protrude outward from the annular retaining ring. The limiting component is used to constrain the movement space of the second spring and prevent it from falling off. The setting of the limit groove creates a space for the block to move in and out.
[0013] The upper outer side of the card block is recessed inward to form a groove; the second spring is provided with several springs; the number of the limiting members matches the number of the second springs.
[0014] The connecting pipe is equipped with several turbulence-disrupting plates; the base has a positioning groove around its outer perimeter, and a second sealing ring is fitted inside the positioning groove, with the outer side of the second sealing ring abutting against the side wall of the annular retaining ring. The turbulence-disrupting plates condense and recirculate the discharged water vapor, preventing excessive discharge of high-temperature steam and potential damage. The cooperation between the positioning groove and the second sealing ring improves the seal between the lid and the body, facilitating heating and pressurization.
[0015] Compared with existing technologies, the advantages of this utility model are as follows: This kettle has a pressure boosting and pressure holding function, which can adjust the pressure inside the kettle to avoid excessive pressure and reduce the problem of injury from venting; by turning the knob, the functions of pressurizing, venting, and pouring water can be realized; This kettle is convenient to use and can be operated with one button through dual valve linkage control, which solves the problems of complex operation, easy misoperation, and poor sealing of traditional multi-functional pressure kettles, and realizes efficient pressurization for boiling water and safe pressure release for drainage.

Detailed Implementation
[0046] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0047] Example
[0048] See Figures 1 to 29This is a multi-functional pressure kettle, comprising a kettle body 1, a handle 12, and a lid. The kettle body 1 has a spout 13 and an annular retaining ring 11 at its opening. The lid includes a base 2, a locking module, a valve core module, and an adjustment module. The locking module is mounted on the base 2 and is engaged or disengaged by pressing the annular retaining ring 11. The base 2 has a first vent 21 and a second vent 22. The valve core module includes a working valve core 8, a safety valve core 9, and a fixing seat 3. The fixing seat 3 has a first sleeve 31 for mounting the working valve core 8 and a second sleeve 32 for mounting the safety valve core 9. The adjustment module is mounted on the fixing seat 3. On the fixed seat 3, the adjustment module is equipped with an adjustment rod 4 for controlling the working valve core 8 and the safety valve core 9 to achieve the function of one valve core rising and the other valve core falling; between the base 2 and the fixed seat 3, there is a drain port 33 and a connecting pipe 34 connecting the first sleeve 31 and the second sleeve 32; controlled by the adjustment rod 4, the working valve core 8 opens or closes the first vent 21, and the safety valve core 9 opens or closes the second vent 22; the first vent 21 and the second vent 22 open and close synchronously; the first vent 21, the second vent 22, the connecting pipe 34 and the drain port 33 form a drainage channel, and the drain port 33 is aligned with the drain spout 13.
[0049] The first vent 21 and the second vent 22 open or close simultaneously. When both vents are open, they form a drainage channel together with the connecting pipe 34 and the drain outlet 33. When the multi-functional pressure kettle is not tilted, gas can flow out through the drainage channel. When the multi-functional pressure kettle is tilted, water is discharged from the kettle through the drainage channel, drain outlet 33, and pouring spout 13. The locking module can fasten or loosen the kettle body 1. The working valve core 8 is used to control the opening and closing of the first vent 21, and the safety valve core 9 is used to control the opening and closing of the second vent 22. The adjusting rod 4 of the adjusting module controls the working valve core 8 and the safety valve core 9 to achieve the function of raising and lowering one valve core and lowering the other, thereby forcing the two vents to open or close. When the two vents are closed, the drainage channel is closed, realizing the pressure increase and pressure maintenance function, increasing the pressure inside the kettle, which is beneficial for boiling water. When the two vents are closed, the drainage channel can discharge gas, realizing the pressure relief function. When water needs to be poured out, the kettle body 1 is tilted again, and the water can flow out of the kettle through the drainage channel. This structure can realize the function of one-button control of venting and pressure relief. The locking module is used to control the opening and closing of the lid and the body 1. The connecting pipe 34 is used to guide the water vapor from the second vent 22 to the first vent 21 and into the drain outlet 33.
[0050] The first sleeve 31 is provided with a first guide cylinder 35. The lower end of the first guide cylinder 35 is connected to the first sleeve 31, and its upper end opening penetrates through the upper side of the fixed base 3. The lower end of the first guide cylinder 35 is folded inward to form a first protruding ring 351. The working valve core 8 includes a valve disc 81 and a first valve column 82 fixed to its center. The upper section of the first valve column 82 is provided with a second protruding ring 83. The upper section of the first valve column 82 is located inside the first guide cylinder 35 and can slide along it. The second protruding ring 83 moves with the first valve column 82 and is close to or away from the first protruding ring 351. The valve disc 81 is located below the base 2 and closes or opens the first exhaust hole 21 as the first valve column 82 moves. The upper end of the first valve column 82 touches the end of the adjusting rod 4. The cooperation between the second protruding ring 83 and the first protruding ring 351 prevents the working valve core 8 from falling off and restricts its range of motion. The valve disc 81 is used to close or open the first exhaust port 21, thereby realizing the function of exhausting pressure or draining water. In this embodiment, the first valve column 82 located below the second protruding ring 83 can be configured as a detachably connected and fixed valve column. The upper valve column is inserted from the first guide cylinder 35 and then detachably connected and fixed to the lower valve column that enters from below the first sleeve 31.
[0051] The second sleeve 32 has a mounting hole 321 at its top; the valve core module also includes a first spring 93 and a washer 94; the safety valve core 9 includes a gravity valve core body located at the bottom and a second valve column 91 located at the top. The lower part of the gravity valve core body protrudes outward to form a third protruding ring 92. The diameter of the second valve column 91 is smaller than the diameter of the gravity valve core body; the second valve column 91 passes through the mounting hole 321 and can slide along it. The first spring 93 is sleeved on the outer periphery of the safety valve core 9, with its lower end abutting against the third protruding ring 92 and its upper end abutting against the top wall of the second sleeve 32; the washer 94 is sleeved on the outer periphery of the second valve column 91, with its lower side abutting against the top of the gravity valve core body; the lower end of the gravity valve core body can movably close or open the second exhaust port 22. The first spring 93 has elasticity and tends to push the gravity valve core body towards the second vent 22, which can ensure the function of sealing the second vent 22; the washer 94 is used to form a seal around the mounting hole 321 to prevent water vapor from overflowing from the mounting hole 321 and contaminating the inside of the lid.
[0052] The adjustment module also includes a knob 7, a panel 6, an adjustment base 5, a screw 61, and a rotating shaft 62. The screw 61 passes through the adjustment base 5 and the panel 6 in sequence and is then tightened into the knob 7. The knob 7 has a locking hole 71. The upper side of the adjustment base 5 has a boss 51, and a pair of protrusions 52 are provided on one of its opposite sides. One of the protrusions 52 extends downward to form a locking member 53. The boss 51 is fitted into the locking hole 71, and the adjustment base 5 rotates with the knob 7 through the engagement of the boss 51 and the locking hole 71. The side wall of the locking member 53 is cut to form a first inclined surface 531. When the adjustment base 5 rotates counterclockwise, the first inclined surface 531 is located on the front side of the locking member 53, and the plane below the boss 51 that is in contact with the first inclined surface 531 forms a working surface 532. The lower side of the panel 6 has a connector with a first rotating shaft hole 63. The middle section of the adjustment rod 4 is cut downward on both sides to form a second inclined surface 41, and a pressing part is provided at the lower part of one end of the adjustment rod 4. 42, its other end is bent downwards and forms a U-shaped fork 43 at its end. The transition area between the bent part and the middle section of the adjusting rod 4 arches upwards to form a bent arm. A second pivot hole 44 is opened at the bent arm to pass through it. The rotating shaft 62 passes through the second pivot hole 44 and the first pivot hole 63 to hinge the adjusting rod 4 to the panel 6. The top of the safety valve core 9 protrudes outwards to form a fourth protruding ring 95. The U-shaped fork 43 is locked on the outer periphery of the upper section of the safety valve core 9 and located below the fourth protruding ring 95. The pressing part 42 presses or releases the top of the working valve core 8 as the adjusting rod 4 rotates. The first inclined surface 531 squeezes or releases the second inclined surface 41 as the knob 7 rotates, causing the adjusting rod 4 to sink or float. The U-shaped fork 43 lifts or lowers the fourth protruding ring 95 as the adjusting rod 4 moves. When the pressing part 42 presses the top of the working valve core 8 tightly, the working surface 532 of the adjusting seat 5 presses on the upper side of the adjusting rod 4. The engagement of the boss 51 and the locking hole 71 allows the adjusting seat 5 to rotate synchronously when the knob 7 is turned. The U-shaped fork 43 is used to lift or lower the safety valve core 9. The rotating shaft 62 engages with the first rotating shaft hole 63 and the second rotating shaft hole 44 to hinge the adjusting rod 4 to the panel 6, making the adjusting rod 4 a lever. The lever principle is used to adjust both ends of the adjusting rod. When the adjusting seat 5 rotates counterclockwise, the first inclined surface 531 of the locking piece 53 presses against the second inclined surface 41 of the middle section of the adjusting rod 4, forcing the adjusting rod 4 on the side where the pressing part 42 is located to move down. When the pressing part 42 presses tightly against the top of the working valve core 8, the working surface 532 of the locking piece 53 of the adjusting seat 5 presses against the upper side of the adjusting rod 4, forming a stable working state.
[0053] The adjustment module also includes a spring post 73; the panel 6 has a first central hole, a first positioning hole 64 and a second positioning hole 65 on its upper side, and a positioning post 66 and a limiting block 67 on its lower side; a pair of positioning posts 66 are provided, located on both sides of the panel 6; a pair of limiting blocks 67 are provided, symmetrically distributed on both sides of the panel 6, symmetrically distributed on the opposite side of the first central hole; a pair of connecting parts are provided, located on both sides of the panel 6; the knob 7 has a third positioning hole 72, and the adjustment seat 5 has a second central hole; the screw 61 passes through the second central hole and the first central hole in sequence and is then tightened into the threaded hole in the center of the knob 7; the spring post 73 The spring post 73 is positioned within the third positioning hole 72 and slides between the first positioning hole 64 and the second positioning hole 65 as the knob 7 rotates. An indicator mark is provided on the top side of the knob 7 opposite to the third positioning hole 72 to indicate the position of the spring post 73. The panel 6 is held between the knob 7 and the adjusting seat 5. Any protrusion 52 is located within the arc-shaped groove formed between the two limiting blocks 67 and can slide within this groove. A pair of third sleeves 36 are provided in the middle of the fixing seat 3, and the two positioning posts 66 are fitted inside the third sleeves 36. Hooks 68 are provided at both ends of the long axis of the panel 6, and the hooks 68 engage with the sides of the fixing seat 3. The first positioning hole 64 and the second positioning hole 65 allow the spring post 73 to slide within the two positioning hole intervals; the two positioning holes represent the limit positions of the spring post 73's movement. The cooperation between the positioning post 66 and the third sleeve 36 constrains the position of the panel 6 and the fixing seat 3. The limiting blocks 67 constrain the range of motion of the protrusion 52. The hook 68 allows the two ends of the panel 6 to be fastened to the sides of the mounting base 3. The spring post 73 is a component of existing mature technology, which is formed by the cooperation of a tactile post and a tension spring. A steel ball is pushed against the lower side of the tension spring. When the knob 7 is turned, the steel ball is forced to move against the upper side of the panel 6 by the elastic force, and slides back and forth between the first positioning hole 64 and the second positioning hole 65 and is placed into either positioning hole.
[0054] The width of the U-shaped fork 43 is smaller than the outer diameter of the fourth protruding ring 95, which can prevent the safety valve core 9 from being disengaged from the control of the U-shaped fork 43.
[0055] The valve disc 81 has an annular groove, within which a first sealing ring 84 is installed. When the working valve core 8 closes the first vent hole 21, the upper side of the first sealing ring 84 abuts against the bottom surface of the base 2 surrounding the first vent hole 21. Several ribs 85 are evenly distributed around the lower outer periphery of the first valve stem 82, with the lower ends of the ribs 85 connected to the valve disc 81. The first sealing ring 84 forms a seal between the valve disc 81 and the lower side of the base 2 surrounding the first vent hole 21, improving sealing performance. The ribs 85 enhance the stability of the connection between the first valve stem 82 and the valve disc 81.
[0056] The locking module includes a locking block 10 and a second spring 101. Two locking blocks 10 are symmetrically arranged, with the center of the lid as the inner side. The outer side of the locking block 10 extends outward to form a guide post 102, and the inner side of the locking block 10 is provided with a limiting member 103. The base 2 has a second guide cylinder 23, and the guide post 102 is sleeved in the second guide cylinder 23 and can slide along it. One end of the second spring 101 is locked on the limiting member 103 of one side of the locking block 10, and the other end of the second spring 101 is locked on the limiting member 103 of the other side of the locking block 10. The upper side of the fixed seat 3 is recessed downward to form a recess 37. The wall surface of the recess 37 near the center of the fixed seat 3 has a limiting groove 38 that communicates with the recess 37. The locking block 10 is located in the limiting groove 38 and extends out of the space of the recess 37. When both hands hold the pair of locking blocks 10, the guide post 102 releases the annular retaining ring 11. When the locking block 10 is released, the guide post 102 locks the annular retaining ring 11. The second spring 101 is designed to hold the two locking blocks 10 in place, ensuring they always protrude outwards, and causing the guide post 102 to protrude outwards from the locking post annular retaining ring 11. The limiting member 103 is designed to constrain the movement space of the second spring 101, preventing it from falling off. The limiting groove 38 is designed to create movement space for the locking blocks 10 to move in and outwards.
[0057] The upper outer side of the locking block 10 is recessed inward to form a groove 104; several second springs 101 are provided; the number of limiting members 103 matches the number of second springs 101. The groove 104 is designed to facilitate gripping and locking by the user's hand.
[0058] The connecting pipe 34 is equipped with a few turbulence deflectors 341; the base 2 has a positioning groove 24 around its outer periphery, and a second sealing ring 25 is fitted inside the positioning groove 24, with the outer side of the second sealing ring 25 abutting against the side wall of the annular retaining ring 11. The turbulence deflectors 341 can condense and reflux the discharged water vapor, preventing excessive discharge of high-temperature steam and potential damage. The cooperation between the positioning groove 24 and the second sealing ring 25 improves the sealing between the lid and the body 1, which is beneficial for heating and pressurization.

[0080] Working principle of this embodiment
[0081] 1) When knob 7 is turned to the first working position (aligned with the first positioning hole 64), the kettle lid is in the normally open state. At this time, the working surface 532 of the adjusting seat 5 presses the adjusting rod 4 down, thereby causing the working valve core 8 to descend and the safety valve core 9 to rise, creating a drainage channel connecting the outside to the inside of the kettle. In this state, the gas inside the kettle can be discharged to the outside through the drainage channel, realizing the venting function. After venting is completed, tilt the kettle towards the pouring spout 13 to pour water. Under the action of gravity, the liquid inside the kettle descends through the working valve core 8, and the safety valve core 9 rises, creating a drainage channel and a connecting channel set by the fixing seat 3, which then flows out through the spout.
[0082] 2) When knob 7 is turned to the second working position (aligned with the second positioning hole 65), the kettle lid is in the working state. At this time, the working surface 532 of the adjusting seat 5 is separated from the pressure adjusting rod. Under the action of the first spring 93, the safety valve core 9 is pressed down, sealing the channel (second sleeve 32 and second exhaust hole 22) set below the safety valve core 9. At the same time, it drives the pressure adjusting rod to press down, causing the pressure adjusting rod near the safety valve end to tilt upward. At this time, the kettle is heated. As the temperature rises, the gas inside the kettle pushes up the working valve core 8, sealing the gas with the external drainage channel, forming a sealed space inside the kettle. The pressure inside the kettle rises rapidly. When the pressure inside the kettle reaches the set value, the air pressure pushes up the safety valve core 9, and the channel (second sleeve 32 and second exhaust hole 22) set below the safety valve core 9 is opened. The gas is discharged into the exhaust channel to relieve pressure. After the pressure inside the kettle drops, under the action of the first spring 93, the channel (second sleeve 32 and second exhaust hole 22) set below the safety valve core 9 is sealed again, so that the pressure inside the kettle remains stable.
[0083] This embodiment also has the following advantages:
[0084] 1) Dual-valve coordinated control technology
[0085] In this embodiment, the working valve core 8 and the safety valve core 9 are synchronously raised and lowered by the linkage control of the adjusting rod 4, so as to realize the synchronous opening and closing of the first exhaust port 21 and the second exhaust port 22, and ensure the precise switching between the pressure boosting and pressure holding and the pressure relief and drainage functions.
[0086] It can avoid the risk of single valve core failure and improve the reliability of pressure control; the linkage design simplifies the operation logic, and users only need to rotate knob 7 to switch functions (such as pressurizing when boiling water and depressurizing when pouring water).
[0087] 2) Modular sealing and drainage channel design
[0088] The first vent 21, the second vent 22, the connecting pipe 34, and the drain outlet 33 form an integrated drainage channel. Combined with the coordinated action of the working valve core 8 and the safety valve core 9, the directional discharge of gas and water is achieved.
[0089] Pressure boosting and holding stage: The double vents are closed to increase the pressure inside the kettle and accelerate the boiling efficiency.
[0090] Pressure relief and drainage stage: Dual vents open simultaneously, and gas is discharged through the drainage channel. When pouring water, the water flows smoothly out of the drain outlet 33 and the pouring spout 13, avoiding the risk of steam splashing.
[0091] 3) Multiple sealing protection mechanisms**
[0092] The working valve core 8 has a valve disc 81 with a first sealing ring 84, the safety valve core 9 seals the mounting hole 321 with a gasket 94, and the base 2 has a second sealing ring 25 on its outer periphery, forming a three-stage sealing structure. This prevents high-temperature steam leakage, improves the pressure stability inside the kettle, and reduces the risk of scalding.
[0093] 4) Anti-detachment structural 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 engaged with the fourth protruding ring 95 by the U-shaped fork 43, ensuring the stability of the valve core's movement trajectory. This prevents the valve core from falling off due to pressure fluctuations or vibrations, thus extending its service life.
[0095] 5) One-click operation and status feedback
[0096] The adjustment module drives the tilting surface and lever mechanism (adjusting rod 4) via knob 7, which in turn presses the working valve core 8 and lifts the safety valve core 9. Combined with the gear design of spring column 73 and positioning hole, it provides clear operating feel and status feedback. Users can intuitively switch between "pressure boosting" and "pressure relief" modes by rotating knob 7, which is convenient and reduces the possibility of misoperation.
[0097] 6) Convenient opening and closing design of the card-locking module
[0098] The dual locking blocks 10 are symmetrically arranged, and the guide post 102 and the annular retaining ring 11 are quickly engaged / released through the elastic reset of the second spring 101. The cover can be opened with a single hand press, and the spring force automatically locks it when closed, balancing sealing and ease of operation.
[0099] 7) 341 condensation reflux technology for baffles
[0100] A baffle plate 341 is installed inside the connecting pipe 34 to extend the steam flow path and promote condensation. This reduces heat waste and the risk of burns caused by the direct discharge of high-temperature steam, and improves energy efficiency.
[0101] 8) Gravity valve core adaptive adjustment
[0102] The gravity valve core body of the safety valve core 9 ensures that the second exhaust port 22 automatically closes when not tilted, through the combined action of the preload of the first spring 93 and gravity.
[0103] 9) Enhance structural stability
[0104] The first valve stem 82 is connected to the valve disc 81 via the rib plate 85, and the bent arm design of the adjusting rod 4 enhances its resistance to deformation. This improves the structural strength of key components under high pressure and avoids fatigue damage caused by long-term use.

This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
