Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an electric kettle lid, an electric kettle, and a method of using the same. Background Technology

[0002] Electric kettles are common household appliances. An electric kettle mainly consists of a kettle body and a lid, with the lid placed on the kettle body.

[0003] However, existing electric kettles still have some shortcomings in use.

[0004] 1. In the process of boiling water, the steam in the existing electric kettle is ejected upwards. When users pick up the kettle, they are very likely to be scalded by the steam. Moreover, the steam splashes upwards and can easily wet the platform on which the kettle is placed, causing water stains on the heating base, which may lead to a short circuit and cause an accident.

[0005] 2. When pouring boiling water, the water in the kettle is very likely to flow down the spout and the kettle wall; therefore, boiling water is wasted during the pouring process, and the flowing boiling water wets the surrounding area.

[0006] 3. Existing kettles easily dissipate heat after boiling water, causing the water inside to cool down rapidly; and water is also prone to spilling from the spout when the kettle is moved.

[0007] To address the above-mentioned problems, this invention proposes an electric kettle lid, an electric kettle, and a method for using the same. Summary of the Invention

[0008] The purpose of this invention is to solve the problems of existing electric kettles, such as steam spraying upwards and easily scalding users, water in the kettle easily flowing down the spout and kettle wall, heat inside the kettle easily dissipating from the spout, and water easily spilling from the spout during movement. Therefore, this invention proposes an electric kettle lid, an electric kettle, and a method for using the kettle.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An electric kettle lid includes a lid with an exhaust pipe fixedly inserted inside the lid. A rotating ring is rotatably sleeved on the outer wall of the exhaust pipe. Multiple air outlets are fixed on the outer wall of the rotating ring and are connected to the rotating ring for discharging water vapor downwards.

[0011] It also includes a pot body, the top of which is fixed with a spout and a lid is placed on top of the spout. The pot body has a spout and a handle fixed on its two opposite sides.

[0012] It also includes an arc-shaped cover fixed to the top of the kettle lid, which is used to discharge the water condensed on the arc-shaped cover to the surrounding area and soften the dust and dirt on the arc-shaped cover. The exhaust pipe is fixedly inserted through the arc-shaped cover. A display screen is fixedly embedded in the top of the kettle lid. A temperature sensor is fixedly embedded in the bottom inner wall of the kettle lid, and the temperature sensor is electrically connected to the display screen to display the water temperature inside the kettle on the display screen.

[0013] A snap-fit ​​structure is installed on the outer wall of the lid and the spout to connect the lid and the spout.

[0014] The exhaust structure, located inside the exhaust stack, is used to allow water vapor to be discharged downwards through the exhaust stack;

[0015] A collection structure is located on one side of the lid and below the spout to prevent water from splashing out of the spout.

[0016] In one possible design, the snap-fit ​​structure includes multiple snap blocks fixed to the outer wall of the lid, multiple U-shaped snaps fixed to the outer wall of the spout, and the snap blocks cooperating with the U-shaped snaps to secure the lid to the spout. A sealing gasket is fixed to the bottom of the lid, and a lid rim ring is fixed to the bottom of the lid, with the outer wall of the lid rim ring fitting against the inner wall of the spout. A rubber step is fixed inside the spout, located at the bottom of the lid rim ring. The rubber step and lid rim ring cooperate to increase the sealing between the lid and the spout, and the pushing force of the rubber step on the lid rim ring and the pushing force of the sealing gasket on the lid can increase the tightness of the engagement between the snap blocks and the U-shaped snaps. The lid is placed on the spout, pressed and rotated until the snap blocks and U-shaped snaps engage. The elasticity of the rubber step against the lid rim ring and the sealing gasket against the lid allows the snap blocks and U-shaped snaps to be tightly engaged, completing the snap-fit ​​connection between the lid and the kettle body, facilitating subsequent boiling of water.

[0017] In one possible design, the exhaust structure includes an exhaust groove at the bottom of the exhaust stack, a fixed plate fixed within the exhaust groove, and a sliding plate slidably connected above the fixed plate within the exhaust groove. Both the fixed plate and the sliding plate have multiple exhaust holes, which are staggered. The cooperation between the fixed plate and the sliding plate seals the exhaust groove. A clearance groove is provided at the top of the exhaust stack, and a sliding rod is fixed to the top of the sliding plate. The top end of the sliding rod extends slidably into the clearance groove and is fixed with a top plate. Multiple through holes are provided inside the exhaust stack. Above the sliding plate, the rotating ring and the air outlet groove are connected by a through hole. The bottom of the air outlet cylinder is provided with multiple exhaust holes. Water vapor enters the air outlet groove. When the pressure inside the kettle is greater than the elastic force of the first spring, the water vapor pushes the sliding plate upward. Then, the water vapor enters the rotating ring through the through hole and is sprayed onto the curved lid through the exhaust holes. The water vapor is then discharged downward to prevent the user from being scalded. The downward sprayed water vapor condenses on the top of the curved lid, and water droplets adhere to the curved lid, softening the dust and dirt on the curved lid, making it easier for the user to clean the curved lid and ensuring the aesthetics of the kettle lid.

[0018] In one possible design, multiple arc-shaped plates are fixed to the top inner wall of the rotating ring, and the arc-shaped plates cooperate with the through holes to drive the rotating ring to rotate. The water vapor injected into the rotating ring drives the rotating ring to rotate through the arc-shaped plates, and the rotating ring drives the air outlet to rotate. In turn, the air outlet can evenly discharge water vapor to the top of the lid, softening the dust and dirt on the top of the lid, making it easier for the user to clean the curved lid and ensuring the lid's aesthetics.

[0019] In one possible design, the top of the exhaust pipe is provided with a cover plate, the bottom of the cover plate is fixed with a nut, the relief groove is provided with an internal thread, and the nut is threadedly connected to the relief groove. A first spring is provided between the nut and the top plate. When the first spring experiences elastic fatigue after long-term use, causing the sliding plate to fail to effectively fit with the fixed plate, the cover plate and nut can be loosened to easily replace the first spring, ensuring that the sliding plate and the fixed plate can effectively fit together.

[0020] In one possible design, the collection structure includes a collection box and a storage box fixed to one side of the kettle body, both located below the spout. A connecting pipe is fixed to the bottom of the collection box, with its bottom end extending into the storage box. A drain hole with a sealing plug is provided on one side of the storage box. A guide rod is fixed to the bottom of the spout, with its bottom end fixed to one side of the kettle lid, guiding water spilled from the spout into the collection box. When water needs to be poured, the water in the kettle body is poured out through the spout, flowing through the bottom of the spout, the guide rod, and the outer wall of the kettle body before entering the collection box. The collection box collects the water into the storage box, and the water can later be drained through the drain hole on one side of the storage box, thus preventing water droplets from spilling from the spout during pouring.

[0021] In one possible design, a first arc-shaped sealing ring is fixed to the outer wall of the lid rim, and a first arc-shaped groove is provided on the inner wall of the spout to cooperate with the first arc-shaped sealing ring, thereby increasing the sealing between the lid and the spout. A tea filter is provided inside the pot, and a fixing ring is fixed to the outer wall of the tea filter. A second arc-shaped sealing ring is fixed to the outer wall of the fixing ring. A second arc-shaped groove is provided on the inner wall of the lid rim, and the second arc-shaped groove cooperates with the second arc-shaped sealing ring to engage the tea filter with the lid rim. In addition, when it is necessary to brew flower tea, the flower tea is placed in the tea filter, and the fixing ring is engaged with the second arc-shaped sealing ring into the second arc-shaped groove to complete the engagement between the tea filter and the lid. Thus, after boiling water, the tea filter can be removed when the lid is opened.

[0022] In one possible design, a sealing ring for sealing the spout is slidably connected to the inner wall of the kettle body. An L-shaped pressure plate is fixed to the top of the sealing ring, and the top of the L-shaped pressure plate extends slidably to the outside of the kettle body. A vertical rod slides through the handle, and the top of the vertical rod is fixedly connected to the bottom side of one side of the L-shaped pressure plate. A second spring is fitted on the outer wall of the vertical rod and fixedly connected to the top of the handle, and the top of the second spring is fixedly connected to the bottom side of one side of the L-shaped pressure plate. When the water in the kettle boils, the pressure inside the kettle body is insufficient to drive the steam to push the sliding plate upward. Under the action of the first spring, the sliding plate fits against the fixed plate, sealing the vent. The sealing ring also seals the spout under the action of the second spring, preventing the heat inside the kettle body from being discharged to the outside through the spout and the exhaust pipe, effectively keeping the kettle warm. Furthermore, when moving the kettle body, it also prevents water from spilling out of the kettle body through the spout.

[0023] An electric kettle, including the type of electric kettle lid mentioned above.

[0024] This application discloses a method for using an electric kettle lid, comprising the following steps:

[0025] S1. When using, open the lid, pour in drinking water, then close the lid and rotate it until the locking block and U-shaped buckle are firmly engaged. The elasticity of the rubber step and sealing gasket ensures a seal, making it easy to boil water. When brewing flower tea, place the flower tea in the tea strainer and use the second arc groove and second arc sealing ring to secure the tea strainer to the bottom of the lid, making it easy to remove after boiling water.

[0026] S2. When boiling water, steam gathers through the designed steam outlet groove and staggered steam outlet holes. When the pressure increases to overcome the resistance of the first spring, it pushes the sliding plate to move up, allowing steam to enter the rotating ring, drive it to rotate, and spray it downward onto the curved cover through the exhaust hole, which not only prevents scalding but also helps with cleaning.

[0027] S3. If the first spring becomes fatigued due to long-term use, the cover plate and nut can be easily loosened and the spring replaced to ensure effective contact between the sliding plate and the fixed plate.

[0028] S4. After the water boils, the steam pressure decreases. The sliding plate returns to its original position under the action of the first spring and closes the steam outlet. At the same time, the sealing ring closes the spout under the action of the second spring to reduce heat loss, maintain water temperature, and prevent water from splashing out during handling.

[0029] S5. When pouring water, gently press the L-shaped pressure plate to release the spout. The water will flow smoothly and flow into the collection box along the bottom of the spout and the outer edge of the guide rod, eventually flowing into the storage box and being discharged through the drain hole, effectively preventing water droplets from spilling when pouring.

[0030] Beneficial effects:

[0031] In this invention, a fixed plate is fixed inside the air outlet groove, and a sliding plate is slidably connected inside the air outlet groove. Both the fixed plate and the sliding plate have multiple air outlet holes. The exhaust pipe has multiple through holes, and a rotating ring is rotatably fitted onto the outer wall of the exhaust pipe. The bottom of the air outlet pipe has multiple exhaust holes. Water vapor enters the air outlet groove and pushes the sliding plate upwards. Then, the water vapor enters the rotating ring through the through holes and is discharged downwards through the exhaust holes, preventing the user from being scalded.

[0032] In this invention, multiple arc-shaped plates are fixed to the top inner wall of the rotating ring, and the arc-shaped plates cooperate with the through holes; the water vapor injected into the rotating ring drives the rotating ring to rotate through the arc-shaped plates, and the rotating ring drives the air outlet to rotate, so that the air outlet can evenly discharge water vapor to the top of the lid, softening the dust and dirt on the top of the lid, making it easier for users to clean the curved lid and ensuring the aesthetics of the lid;

[0033] In this invention, the collection structure includes a collection box and a storage box fixed to one side of the kettle body. The bottom of the collection box and the top of the storage box are connected by a connecting pipe. A guide rod is fixed to the bottom of the spout, and the bottom end of the guide rod is fixed to one side of the kettle lid. When pouring water, the water in the kettle body is poured out through the spout, and the water flowing out of the spout flows through the bottom of the spout, through the guide rod and the outer wall of the kettle body, and enters the collection box. The collection box collects the water into the storage box, and the water can be discharged through the drain hole on one side of the storage box later, thereby preventing water droplets from spilling through the spout during the pouring process.

[0034] In this invention, a sealing ring is slidably connected to the inner wall of the kettle body, and an L-shaped pressure plate is fixed to the top of the sealing ring. The top of the L-shaped pressure plate extends slidably to the outside of the kettle body. A vertical rod fixedly connected to the L-shaped pressure plate slides through the handle. When the water in the kettle body boils, the pressure inside the kettle body is insufficient to drive the steam to push the sliding plate upward. Under the action of the first spring, the sliding plate fits against the fixed plate, sealing the vent hole. The sealing ring also seals the spout under the action of the second spring, preventing the heat inside the kettle body from being discharged to the outside through the spout and the exhaust pipe, effectively keeping the kettle warm. Furthermore, when moving the kettle body, it also prevents water inside the kettle body from spilling to the outside through the spout.

[0035] In this invention, the release of steam can be controlled during the boiling process to prevent users from being scalded. The condensation of steam can wet the top of the lid and soften dust and dirt, making it easier to clean the lid. In addition, the cooperation of the fixing plate, sliding plate and sealing ring can effectively seal the inside of the kettle body and the lid, keeping the boiling water warm. During the pouring process, the water can be collected through the collection box to prevent water from splashing. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] Example 1

[0049] Reference Figures 1-3 An electric kettle lid, used in the field of household appliances, comprises a lid 1 and an exhaust pipe 14. The lid 1 is circular, with the exhaust pipe 14 fixedly inserted through its center. The exhaust pipe 14 is made of high-temperature resistant and corrosion-resistant metal or alloy material to ensure long-term stability and safety.

[0050] Reference Figure 7 Rotating ring 22 and vent 24: A rotating ring 22 is rotatably fitted on the outer wall of the exhaust pipe 14, and the rotating ring 22 can rotate freely around the exhaust pipe 14. Multiple vents 24 are evenly fixed on the outer wall of the rotating ring 22, and each vent 24 is connected to the inside of the rotating ring 22 to discharge water vapor downwards, preventing water vapor from rising directly and condensing on the lid 1.

[0051] Reference Figure 5 The lid 11 has an arc-shaped surface, a display screen 12, and a temperature sensor 13. The top of the lid 1 is fixedly fitted with an arc-shaped surface 11. The design of the arc-shaped surface 11 helps to allow water condensed on it to slide naturally to the sides, reducing water accumulation. A display screen 12 is also fixedly embedded in the top of the lid 1 to display the water temperature inside the kettle body 2. A temperature sensor 13 is fixedly embedded in the inner wall of the bottom of the lid 1. The temperature sensor 13 is electrically connected to the display screen 12 to measure and display the water temperature in real time.

[0052] Reference Figures 1-3 The kettle body 2 and the spout 3: The kettle body 2 is in the shape of a traditional electric kettle, with a spout 3 fixed to the top. The lid 1 can be placed on top of the spout 3 to achieve a seal. The kettle body 2 is fixed with a spout 34 and a handle 40 on both sides for easy pouring and lifting.

[0053] Reference Figure 3 and Figure 4 The snap-fit ​​structure includes snap-fit ​​blocks 4 and U-shaped snap-fits 5. Multiple snap-fit ​​blocks 4, made of elastic material, are fixed to the outer wall of the lid 1, allowing for a certain degree of deformation. Multiple U-shaped snap-fits 5 are fixed to the outer wall of the spout 3. The snap-fit ​​blocks 4 and U-shaped snap-fits 5 cooperate, achieving a fixed connection between the lid 1 and the spout 3 through the elastic deformation of the snap-fit ​​blocks 4. A sealing washer 8 and a lid rim ring 7 are fixed to the bottom of the lid 1. The outer wall of the lid rim ring 7 fits tightly against the inner wall of the spout 3, increasing the seal. A rubber step 6 is also fixed inside the spout 3, located at the bottom of the lid rim ring 7. The cooperation between the rubber step 6 and the lid rim ring 7, along with the thrust of the sealing washer 8, jointly enhances the seal and tightness of the connection between the lid 1 and the spout 3.

[0054] Reference Figures 7-9The exhaust structure includes an exhaust groove 15, a fixed plate 16, and a sliding plate 17. The exhaust pipe 14 has an exhaust groove 15 at its bottom, with a fixed plate 16 fixed inside the groove and a sliding plate 17 slidably connected above it. Both the fixed plate 16 and the sliding plate 17 have multiple exhaust holes 29, which are arranged in an alternating pattern. The exhaust groove 15 is opened and closed by the up-and-down sliding of the sliding plate 17. The exhaust pipe 14 has a clearance groove 19 at its top, and a sliding rod 18 is fixed to the top of the sliding plate 17. The top end of the sliding rod 18 extends slidably into the clearance groove 19 and is fixed with a top plate 20. The exhaust pipe 14 also has multiple through holes 21 located above the sliding plate 17, allowing the rotating ring 22 to communicate with the exhaust groove 15 through the through holes 21. When the water vapor pressure increases, it pushes the top plate 20 and the slide rod 18 to move down, which in turn drives the sliding plate 17 to move down, so that the fixed plate 16 and the air outlet 29 on the sliding plate 17 are misaligned, allowing water vapor to pass through and enter the air outlet 24, and finally be discharged from the exhaust port 25.

[0055] Reference Figure 1 and Figure 2 The collection structure is included on one side of the lid 1 and below the spout 34. A collection tray or a guide channel may be provided. The specific structure of the collection structure is not described in detail in the claims, but can be designed according to actual needs. It is used to receive and guide the water flowing out from the spout 34 port, to prevent water from splashing out of the kettle body 2, and to improve the convenience and safety of use.

[0056] Through the above specific embodiments, the electric kettle lid of the present invention not only achieves effective steam discharge and natural condensation, but also improves the sealing performance and ease of use of the lid 1 and the kettle mouth 3 through the ingenious design of the snap-fit ​​structure and steam venting structure, while avoiding water splashing when pouring water.

[0057] Reference Figure 7 and Figure 9 In practice, multiple evenly distributed arc-shaped plates 23 are fixed to the top inner wall of the rotating ring 22 by welding or screw fastening. The shape and size of these arc-shaped plates 23 match the through holes 21, so that when an external tool, such as a finger or a special tool, contacts and rotates the arc-shaped plates 23 through the through holes 21, it can drive the rotating ring 22 to rotate synchronously. This design is convenient for user operation and can effectively transmit rotational force, ensuring the smooth rotation of the rotating ring 22.

[0058] Reference Figure 7A cover plate 28 is fixed to the top of the exhaust pipe 14 by screws or clips. A nut 27 is welded or threaded to the bottom center of the cover plate 28. Meanwhile, a relief groove 19 with internal threads is provided on the top plate 20 of the lid 1, which matches the thread of the nut 27. When the cover plate 28 and the top plate 20 are mated, the nut 27 is screwed into the relief groove 19, achieving a threaded connection. A first spring 26 is installed between the nut 27 and the top plate 20. This spring is in a compressed state, providing an upward elastic force to the cover plate 28, ensuring a tight seal while also allowing for slight displacement under certain conditions, such as during exhaust.

[0059] Reference Figure 1 and Figure 2 The collection structure is specifically implemented by fixing a collection box 36 and a storage box 38 to one side of the kettle body 2 via screws or slots, both located below the spout 34. A connecting pipe 37 is welded or threaded to the bottom of the collection box 36, with the other end of the connecting pipe 37 extending into the storage box 38 to ensure that water in the collection box 36 can flow smoothly into the storage box 38. A drain hole is provided on one side of the storage box 38, with a removable sealing plug installed inside, allowing the user to drain water from the storage box 38 as needed. Furthermore, a guide rod 35 is welded or threaded to the bottom of the spout 34, with the other end of the guide rod 35 fixed to one side of the kettle lid 1. When water droplets fall from the spout 34, the guide rod 35 guides them into the collection box 36, preventing water droplets from falling onto the kettle body 2 or other unwanted locations.

[0060] Reference Figure 3 and Figure 4 To enhance the seal between the lid 1 and the spout 3, a first arc-shaped sealing ring 10 is fixed to the outer wall of the lid rim 7 using glue or a slot. Simultaneously, a first arc-shaped groove 9 matching the first arc-shaped sealing ring 10 is formed on the inner wall of the spout 3. When the lid 1 is closed on the spout 3, the first arc-shaped sealing ring 10 is embedded in the first arc-shaped groove 9, forming a tight seal. Furthermore, to facilitate the addition of tea leaves or other materials requiring filtration, a tea filter 30 is also provided inside the teapot body 2. A fixing ring 31 is welded or threaded to the outer wall of the tea filter 30, and a second arc-shaped sealing ring 32 is fixed to the outer wall of the fixing ring 31. A second arc-shaped groove 33 matching the second arc-shaped sealing ring 32 is provided on the inner wall of the lid rim ring 7. When the tea filter 30 is placed into the pot body 2 and the pot lid 1 is closed, the second arc-shaped sealing ring 32 is embedded in the second arc-shaped groove 33, realizing the snap-fit ​​fixation between the tea filter 30 and the lid rim ring 7, which is convenient for users to operate and ensures the stability of the tea filter 30.

[0061] An electric kettle, including the type of electric kettle lid mentioned above.

[0062] Example 2

[0063] refer to Figure 3 and Figure 10 An improvement upon Embodiment 1 is made: the inner wall of the kettle body 2 is designed with a sliding connection structure for installing a sealing ring 39. The main function of the sealing ring 39 is to seal the spout 34, preventing water from overflowing from the spout 34. An L-shaped pressure plate 41 is fixedly connected to the top of the sealing ring 39. The top of the L-shaped pressure plate 41 is designed with a sealing sliding structure, which can extend to the outside of the kettle body 2.

[0064] The handle 40 has a sliding vertical rod 42 inside. The top of the vertical rod 42 is fixedly connected to the bottom side of the L-shaped pressure plate 41, ensuring that the vertical rod 42 and the L-shaped pressure plate 41 move synchronously. A second spring 43 is sleeved on the outer wall of the vertical rod 42. The top of the second spring 43 is fixedly connected to the bottom side of the L-shaped pressure plate 41, and the bottom is fixedly connected to the top of the handle 40. The second spring 43 provides a restoring force for the L-shaped pressure plate 41.

[0065] The exposed portion of the L-shaped pressure plate 41 perpendicular to the vertical rod 42 is covered with heat-insulating material, such as silicone or other heat-insulating materials.

[0066] When water needs to be poured, the user can press the L-shaped pressure plate 41 to move it downwards, thereby causing the closing ring 39 to move downwards and opening the spout 34. At this time, the second spring 43 is compressed. After pouring, the user releases the L-shaped pressure plate 41, the second spring 43 returns to its original position, and pushes the L-shaped pressure plate 41 and the closing ring 39 upwards to re-close the spout 34.

[0067] Through the above implementation method, the kettle lid enables convenient water pouring and automatically seals the spout 34 after pouring to prevent water from overflowing. Meanwhile, the material selection of the L-shaped pressure plate 41 ensures its stability and safety under high-temperature conditions.

[0068] A method for using an electric kettle lid includes the following steps:

[0069] S1. When using, open the lid 1, pour drinking water into the pot body 2, place the lid 1 on the pot mouth 3, press the lid 1 and rotate it until the locking block 4 and the U-shaped buckle 5 are engaged. The elasticity of the rubber step 6 against the lid edge ring 7 and the sealing gasket 8 against the lid 1 allows the locking block 4 and the U-shaped buckle 5 to be tightly locked, completing the connection between the lid 1 and the pot body 2, which is convenient for boiling water later. In addition, when it is necessary to brew flower tea, place the flower tea in the tea filter 30 and insert the fixing ring 31 into the second arc-shaped sealing ring 32 into the second arc-shaped groove 33 to complete the connection between the tea filter 30 and the lid 1. Then, after boiling water is finished, the tea filter 30 can be taken out when the lid 1 is opened.

[0070] S2. During the boiling process, steam enters the steam outlet 15. Due to the staggered arrangement of the steam outlets 29 in the fixed plate 16 and the sliding plate 17, the steam accumulates in the kettle body 2. When the pressure in the kettle body 2 is greater than the elastic force of the first spring 26, the steam pushes the sliding plate 17 upward. Then, the steam enters the rotating ring 22 through the through hole 21. The steam injected into the rotating ring 22 drives the rotating ring 22 to rotate through the arc plate 23. The steam is sprayed onto the arc-shaped cover 11 through the exhaust hole 25. The steam is then discharged downward to prevent the user from being scalded. The downward sprayed steam condenses on the top of the arc-shaped cover 11, and water droplets adhere to the arc-shaped cover 11, softening the dust and dirt on the arc-shaped cover 11, making it easier for the user to clean the arc-shaped cover 11 and ensuring the aesthetics of the kettle lid 1.

[0071] S3. In addition, if the first spring 26 experiences elastic fatigue after prolonged use, causing the sliding plate 17 to fail to effectively fit with the fixed plate 16, loosening the cover plate 28 and nut 27 will allow the first spring 26 to be easily replaced, ensuring that the sliding plate 17 and the fixed plate 16 can effectively fit together.

[0072] S4. When the water in the kettle body 2 boils, the pressure inside the kettle body 2 is insufficient to drive the steam to push the sliding plate 17 upward. Under the action of the first spring 26, the sliding plate 17 fits against the fixed plate 16, sealing the vent 29. The sealing ring 39 seals the spout 34 under the action of the second spring 43, preventing the heat inside the kettle body 2 from being discharged to the outside through the spout 34 and the exhaust pipe 14, effectively keeping the kettle body 2 warm. When moving the kettle body 2, it can also prevent the water inside the kettle body 2 from spilling to the outside through the spout 34.

[0073] S5. When water needs to be poured, press the L-shaped pressure plate 41 to release the sealing ring 39 from the spout 34. The water in the kettle body 2 is poured out through the spout 34. The water flowing out from the spout 34 flows through the bottom of the spout 34, through the guide rod 35 and the outer wall of the kettle body 2, and enters the collection box 36. The collection box 36 collects the water into the storage box 38. Later, the water can be discharged through the drain hole on one side of the storage box 38, thus preventing water droplets from spilling through the spout 34 during the pouring process.
