Description

A kettle lid assembly and a kettle Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a kettle lid assembly and a kettle. Background Technology

[0002] In the field of electric kettle technology, existing spill-proof electric kettles on the market exhibit different characteristics. On the one hand, the spill-proof structure of some products is closely related to the structure of the kettle body itself, with its overall design revolving around the kettle body, resulting in a complex structure. On the other hand, some spill-proof electric kettles also have multiple valves within their spill-proof structure. Multiple valves imply complex component assembly and cumbersome operation.

[0003] For example, Chinese utility model patent CN218978600U discloses a tilt-prevention anti-overflow electric kettle, including a kettle body and a lid. The lid has a steam outlet, a first steam outlet channel, a second steam outlet channel, and two steam inlets. One end of each of the first and second steam outlet channels is connected to the steam outlet, and the other end of the first steam outlet channel is connected to one steam inlet. The other end of the second steam outlet channel is connected to the other steam inlet. The two steam inlets are symmetrically arranged and located on both sides of the line connecting the handle and the steam outlet. An anti-overflow valve is also included. The entire structure is extremely complex and costly, resulting in a very high defect rate during production. Furthermore, the conditions for triggering the anti-overflow valve are overly complex, making it impossible to guarantee that water will not overflow when the kettle is tilted.

[0004] Utility Model Content

[0005] The purpose of this application is to provide a kettle lid assembly, including:

[0006] Top cover;

[0007] A bottom cover, which is connected to the top cover to form a cavity, and a water inlet and a steam inlet are provided on the bottom cover;

[0008] A support is disposed within the cavity and connected to the bottom cover. The support divides the cavity into three independent regions: a first region, a second region, and a third region. The support includes a first side and a second side arranged opposite to each other. A water outlet is provided on the first side, and a steam outlet is provided on the second side. Both the water inlet and the water outlet communicate with the first region to form a water outlet channel. Both the steam inlet and the steam outlet communicate with the second region to form a steam channel.

[0009] A first valve assembly, located on the first side of the bracket, is used to control the opening and closing of the water inlet, so as to close the water inlet and close the water outlet when the kettle is boiling water, and to open the water inlet and open the water outlet when the kettle is pouring water.

[0010] The second valve assembly, located on the second side of the bracket, is used to control the opening and closing of the steam outlet. When the kettle is boiling water, the steam outlet is opened to open the steam passage, and when the kettle is in an abnormal tilting state, the steam outlet is closed to close the steam passage.

[0011] This application uses a first valve assembly and a second valve assembly to control the opening and closing of the water outlet channel and the steam channel, respectively. When the kettle is boiling water, the water outlet channel can be closed and the steam channel opened to ensure a normal boiling process. When pouring water, the water outlet channel can be opened for easy pouring, and in case of abnormal pouring, the steam channel can be closed to effectively prevent water from overflowing from the outlet and steam channel. The functions are integrated and reasonable, avoiding the need for too many complex valves.

[0012] As an optional embodiment, the first valve assembly includes:

[0013] A door lock switch is located in the third area and is connected to the bracket;

[0014] The water outlet button is located on the top cover.

[0015] A push rod is located in the first area, one end of which can pass through the bracket and extend into the third area, and is connected to the water outlet button;

[0016] A reset element is disposed between the water outlet button and the bracket, and is used to apply a force to the water outlet button to move it upward and reset it;

[0017] When the water outlet button is pressed down, the water outlet button moves downward, causing the push rod to move downward, so that the other end of the push rod disengages from the water inlet, the water outlet channel opens, and at the same time the water outlet button engages with the door lock switch to lock the water outlet button in the pressed state.

[0018] When the water outlet button is pressed down again, the water outlet button disengages from the door lock switch to release the lock on the water outlet button. Under the action of the reset component, the water outlet button and the push rod move upward to reset. The other end of the push rod closes the water inlet, and the water outlet channel is closed.

[0019] This application utilizes a door lock switch, a water outlet button, a push rod, and a reset component. Pressing down on the water outlet button moves the push rod to open the water outlet channel, and the water outlet button can be locked in the pressed state by engaging with the door lock switch, facilitating continuous water dispensing. Pressing the water outlet button again unlocks it, and the reset component resets the button and push rod to close the water outlet channel. The operation is simple and reliable, and is more convenient and easy to use compared to the complex and cumbersome multi-valve operation method.

[0020] As an optional embodiment, the push rod includes:

[0021] A sealing portion is provided in the first region;

[0022] Two rods, one end of which is connected to the sealing part, and the other end of the two rods passes through the bracket and is respectively connected to the water outlet button. The reset piece is sleeved on the two rods.

[0023] This application places the sealing part of the push rod in the first area, which can better seal the water inlet and ensure the sealing performance when the water outlet channel is closed. The two rods connect the sealing part and the water outlet button, and are fitted with a reset part. This structure makes the connection between the components more stable, and can stably realize the movement of the push rod and the corresponding channel control function during operation, thereby improving the reliability of the overall structure.

[0024] As an optional embodiment, a valve body mounting cavity is provided on the bracket near the steam outlet. The valve body mounting cavity is connected to both the second area and the steam outlet. Steam enters the second area from the steam inlet and flows to the steam outlet through the valve body mounting cavity.

[0025] This application provides a valve body mounting cavity on the bracket near the steam outlet, and connects it with the second area and the steam outlet, providing a reasonable and orderly channel for steam flow. This allows steam to flow smoothly from the steam inlet through the second area and the valve body mounting cavity to the steam outlet, which helps to ensure the stable functioning of the steam channel and avoids potential problems caused by unreasonable channel settings.

[0026] As an optional embodiment, the valve body mounting cavity has a first cavity opening and a second cavity opening on its cavity wall, the first cavity opening communicating with the third region and the second cavity opening communicating with the second region;

[0027] The second valve assembly includes a check valve and a counterweight. The counterweight is located in the third region. The check valve is located in the valve body mounting cavity and can move in the direction from the second cavity opening to the first cavity opening. One end of the check valve passes through the first cavity opening and is connected to the counterweight, and the first end seals the first cavity opening. When the kettle is in an abnormal tilting state, the other end of the check valve moves to the second cavity opening under the action of the counterweight to seal the second cavity opening, and the steam passage is closed.

[0028] This application utilizes the cooperation of a check valve and a counterweight. When the kettle is abnormally tilted, the counterweight is driven by gravity and inertia to move the check valve within the valve body mounting cavity. By sealing the corresponding cavity opening, the steam passage is closed, which can precisely prevent water from overflowing from the steam passage when tilted. The ingenious structural design achieves the key anti-overflow function and is more advantageous than some complex anti-overflow structures with multiple valves and cumbersome operation.

[0029] As an optional embodiment, the check valve includes:

[0030] The valve body has one end connected to the counterweight;

[0031] The housing has a bowl-shaped structure and one end is connected to the other end of the valve body. The other end of the housing extends outward along its outer periphery to form a skirt. The skirt is used to follow the valve body as it moves in the direction from the second cavity to the first cavity, and moves to the second cavity to close the second cavity.

[0032] The valve housing of this application adopts a bowl structure with a skirt. When the valve body moves with the counterweight, the skirt can move with it to the second cavity to seal the cavity. This structure makes the steam passage sealing effect better, enhances the ability to prevent water from overflowing under abnormal tilting conditions, and ensures the reliable realization of the anti-overflow function.

[0033] As an optional embodiment, the valve body mounting cavity is provided with a stepped structure, and the outer peripheral wall of the housing is provided with a limiting bone. The limiting bone is used to limit the range of movement of the housing in the valve body mounting cavity and to prevent the housing from tilting in the valve body mounting cavity when it moves.

[0034] The stepped structure inside the valve body mounting cavity and the limiting rib on the outer peripheral wall of the housing in this application can limit the range of movement of the housing within the valve body mounting cavity and prevent it from tilting during movement. This makes the check valve more stable and accurate during operation (especially in response to the moving sealing action when the kettle is tilted), further improving the stability and reliability of the anti-overflow function.

[0035] As an optional embodiment, the bottom cover includes a first side and a second side disposed opposite to each other, the first side and the second side of the bottom cover corresponding to the first side and the second side of the bracket respectively, and the steam inlet is opened on the cover portion of the bottom cover near its first side.

[0036] This application specifies that a steam inlet is opened on the first side of the bottom cover, which corresponds to the first side of the bracket. This allows steam to enter from the steam inlet of the bottom cover and flow precisely into the corresponding area separated by the bracket, and then flow to the steam outlet. This optimizes the steam flow path, reduces turbulence and energy loss of steam in the lid assembly, improves the efficiency of steam discharge, ensures that steam can be smoothly discharged from the kettle, and guarantees the normal operation of the water boiling process.

[0037] The purpose of this application is to provide a kettle, including a kettle body and the aforementioned kettle lid assembly, wherein the kettle lid assembly is detachably installed on the kettle body.

[0038] This application combines the aforementioned lid assembly with the kettle body to form a kettle, and the lid assembly is detachable for easy use and cleaning. At the same time, the anti-overflow and water flow control functions of the lid assembly are reflected in the kettle as a whole product, improving the practicality and user experience of the kettle product.

[0039] As an optional embodiment, the kettle body is provided with a handle and a steam outlet channel. The handle is provided with a connecting cavity, one end of which is connected to the steam outlet and the other end of which is connected to one end of the steam outlet channel.

[0040] This application features a handle on the kettle body, with a connecting cavity inside to connect the steam outlet and the steam vent. This allows the steam generated during use to be discharged through a reasonable path, ensuring that the steam can be discharged normally and avoiding the inconvenience or safety hazards that may be caused by disorderly steam discharge, thus further improving the overall functional layout of the kettle.

[0041] The beneficial effects of the embodiments of this application are as follows:

[0042] This application features a rationally designed structure. Through the first and second valve assemblies located on both sides of the support, it cleverly achieves multiple functions, including boiling water, pouring water, and preventing overflow. Users only need to press the water dispensing button or utilize the gravity and inertia of the kettle when it is tilted to complete the corresponding action. The operation process is simple and easy to understand, reducing the probability of misoperation and improving the user experience.

[0043] Furthermore, the core anti-overflow structure of this application is located in the lid, which can be adapted to various kettle body structures, greatly reducing the limitations on kettle body design and expanding the scope of application. Attached Figure Description

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0070] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0071] An embodiment of this application provides a kettle lid assembly, as shown in Figures 1 and 14. The kettle lid assembly includes a top cover 1, a bottom cover 2, a bracket 3, a first valve assembly 4, and a second valve assembly 5.

[0072] As shown in Figures 5 and 6, the bottom cover 2 is connected to the top cover 1 to form a cavity. The bottom cover 2 has a water inlet 24 and a steam inlet 25. The first side of the bottom cover 2 is provided with a water outlet 26 connected to the water outlet 31, and the second side opposite to the first side is provided with an outlet corresponding to the steam outlet 32.

[0073] The bottom cover 2 is provided with multiple steam inlets 25 to facilitate the smooth entry of steam into the cavity during the boiling process. A condensate return hole is provided in the middle of the bottom cover 2 to provide a return path for the condensate after the steam liquefies, thus preventing water accumulation.

[0074] As shown in Figure 1, the bracket 3 is disposed in the cavity and connected to the bottom cover 2. The bracket 3 divides the cavity into three independent regions: a first region 21, a second region 22, and a third region 23. The bracket 3 includes a first side and a second side arranged opposite to each other. A water outlet 31 is provided on the first side, and a steam outlet 32 ​​is provided on the second side. The water inlet 24 and the water outlet 31 are both connected to the first region 21 to form a water outlet channel 33. The steam inlet 25 and the steam outlet 32 ​​are both connected to the second region 22 to form a steam channel 34.

[0075] The first valve assembly 4 is located on the first side of the bracket 3 and is used to control the opening and closing of the water inlet 24. When the kettle is boiling water, the water inlet 24 is closed, and the water outlet 33 is closed. When the kettle is pouring water, the water inlet 24 is opened, and the water outlet 33 is opened.

[0076] The second valve assembly 5 is located on the second side of the bracket 3 and is used to control the opening and closing of the steam outlet 32. When the kettle is boiling water, the steam outlet 32 ​​is opened to open the steam passage 34, and when the kettle is in an abnormal tilting state, the steam outlet 32 ​​is closed to close the steam passage 34.

[0077] In this embodiment, when assembling the lid assembly, the bracket 3 is first installed on the bottom cover 2, and then the top cover 1 is tightly connected to the bottom cover 2 to form a closed cavity, thereby cleverly dividing the cavity into a first region 21, a second region 22 and a third region 23 that are independent of each other.

[0078] As shown in Figures 1-4, when the kettle is boiling water, the first valve assembly 4 plays a crucial role, steadily closing the inlet 24 and blocking the water outlet 33 in the first area 21. Water is firmly locked inside the kettle, preventing accidental leakage from the outlet 31. Simultaneously, the second valve assembly 5 opens the steam outlet 32, allowing steam to smoothly enter the second area 22 from the steam inlet 25 of the bottom cover 2, and then orderly exit through the steam outlet 32, ensuring proper steam dissipation during boiling and maintaining a good boiling environment. When water needs to be poured out, the first valve assembly 4 quickly switches its state, precisely opening the inlet 24, immediately connecting the water outlet 33 in the first area 21, allowing water to be poured out smoothly from the outlet 31.

[0079] If the kettle, which is boiling water, suddenly tipes over, the second valve assembly 5 will respond immediately and close the steam outlet 32 ​​at a very fast speed, effectively preventing water from overflowing from the steam channel 34 and avoiding dangerous situations such as scalding.

[0080] This application uses a first valve assembly 4 and a second valve assembly 5 to control the opening and closing of the water outlet channel 33 and the steam channel 34, respectively. When the kettle is boiling water, the water outlet channel 33 can be closed and the steam channel 34 opened to ensure a normal boiling process. When pouring water, the water outlet channel 33 can be opened for easy pouring, while in case of abnormal pouring, the steam channel 34 can be closed to effectively prevent water from overflowing from the water outlet 31 and the steam channel 34. The functions are integrated and reasonable, avoiding the need for too many complex valves.

[0081] In another embodiment, as shown in FIG14, an “∞”-shaped mounting groove is provided on the bottom cover 2, and a bracket sealing ring 36 with a matching shape is provided in the mounting groove. The bracket 3 is connected to the bottom cover 2 by screws, and the bracket sealing ring 36 is used to seal the gap between the bracket 3 and the bottom cover 2.

[0082] The sealing ring 36 ensures that the water outlet channel 33 in the first area 21 and the steam channel 34 in the second area 22 are independent of each other, and the two channels are isolated from each other to avoid water and steam from interfering with each other and to ensure the stable realization of their respective functions. The water outlet channel 33 is dedicated to pouring water, and the steam channel 34 is used for steam discharge and overflow prevention control.

[0083] As an optional embodiment, as shown in Figures 1-4 and 14, the first valve assembly 4 includes a door lock switch 41, a water outlet button 42, a push rod 43, and a reset member 44.

[0084] The door lock switch 41 is located within the third region 23 and connected to the bracket 3. The water outlet button 42 is movably mounted on the top cover 1, which has a mounting hole for the water outlet button. The push rod 43 is located within the first region 21, with one end extending through the bracket 3 into the third region 23 and connected to the water outlet button 42. The reset element 44 is located between the water outlet button 42 and the bracket 3, and is used to apply a force to the water outlet button 42 to move it upward and reset it. The reset element 44 can be a spring.

[0085] When the water outlet button 42 is pressed down, the water outlet button 42 moves downward, causing the push rod 43 to move downward, so that the other end of the push rod 43 disengages from the water inlet 24, the water outlet channel 33 opens, and at the same time the water outlet button 42 engages with the door lock switch 41 to lock the water outlet button 42 in the pressed state.

[0086] When the water outlet button 42 is pressed down again, the water outlet button 42 disengages from the door lock switch 41, thereby releasing the door lock switch 41 from locking the water outlet button 42. Under the action of the reset member 44, the water outlet button 42 and the push rod 43 move upward to reset. The other end of the push rod 43 closes the water inlet 24, and the water outlet channel 33 is closed.

[0087] In this embodiment, the water outlet button 42 is not pressed by external force in the initial state. At this time, under the action of the reset member 44, one end of the push rod 43 is tightly fitted with the water inlet 24, which completely blocks the water inlet 24, so that the water outlet channel 33 is in a closed state and water cannot flow out.

[0088] When the user presses down on the water outlet button 42, the water outlet button 42 overcomes the resistance of the reset member 44 and moves slowly downward. During this process, the water outlet button 42 drives the push rod 43 connected to it to move downward in sync. The other end of the push rod 43 then disengages from the water inlet 24, the water outlet channel 33 opens, and the water is ready to flow out.

[0089] At the same time, the water dispensing button 42 moves to a specific position, precisely engaging with the door lock switch 41. The door lock switch 41 firmly locks the water dispensing button 42, keeping it firmly in the pressed state. In this way, the user can easily and continuously pour water without having to keep pressing the water dispensing button 42, making operation more convenient.

[0090] When the water dispensing is complete and the dispensing operation needs to be stopped, the user presses the water dispensing button 42 down again. The lock between the water dispensing button 42 and the door lock switch 41 is released. Under the action of the reset component 44, the water dispensing button 42 and the push rod 43 quickly move upward to reset. The push rod 43 accurately re-closes the water inlet 24, and the water outlet channel 33 is immediately closed, and the water stops flowing out.

[0091] This application utilizes the cooperation of a door lock switch 41, a water outlet button 42, a push rod 43, and a reset component 44. Pressing down on the water outlet button 42 will move the push rod 43 to open the water outlet channel 33. The button can also engage with the door lock switch 41 to lock it in the pressed state, facilitating continuous water dispensing. Pressing the button again will unlock it, and the button and push rod 43 will reset and close the water outlet channel 33 under the action of the reset component 44. The operation is simple and reliable, and is more convenient and easier to use than the complex and cumbersome multi-valve operation method.

[0092] As an alternative embodiment, as shown in Figures 2 and 14, the push rod 43 includes a sealing portion and two rod portions.

[0093] The sealing part is located in the first region 21. One end of the two rods is connected to the sealing part, and the other end of the two rods passes through the bracket 3 and is connected to the water outlet button 42 respectively. The reset member 44 is sleeved on the two rods.

[0094] In this embodiment, the sealing part is placed in the first region 21, and a sealing ring is provided on the sealing part to seal the gap between the sealing part and the water inlet 24, so as to ensure excellent sealing performance when the water inlet 24 is closed.

[0095] One end of each of the two rods is firmly connected to the sealing part, and the other end passes through the bracket 3 and is tightly connected to the water outlet button 42, so that the connection between the push rod 43 and each component is stable.

[0096] When the water outlet button 42 is activated by external force, it can stably and efficiently drive the sealing part to move, accurately realizing the opening and closing of the water inlet 24; the reset part 44 is sleeved on the two rods, and provides force for the reset of the water outlet button 42 during the reciprocating movement of the push rod 43, ensuring the smooth operation of the entire system.

[0097] As an optional embodiment, as shown in Figures 8 and 9, a valve body mounting cavity 35 is provided on the bracket 3 near the steam outlet 32. The valve body mounting cavity 35 is connected to both the second region 22 and the steam outlet 32. Steam enters the second region 22 from the steam inlet 25 and flows to the steam outlet 32 ​​via the valve body mounting cavity 35.

[0098] In this embodiment, after the steam smoothly enters the second area 22 from the steam inlet 25 of the bottom cover 2, it flows to the steam outlet 32 ​​after passing through the valve body mounting cavity 35. This ensures that the steam can pass through in an orderly manner along a predetermined route throughout the entire process from entry to exit, completely eliminating the hidden dangers of steam turbulence or blockage, and providing strong support for the efficient operation of the kettle.

[0099] As an optional embodiment, as shown in Figures 9 and 10, the valve body mounting cavity 35 is provided with a first cavity 351 and a second cavity 352 on the cavity wall. The first cavity 351 is connected to the third region 23, and the second cavity 352 is connected to the second region 22.

[0100] As shown in Figures 11-13, the second valve assembly 5 includes a check valve 51 and a counterweight 52. The counterweight 52 is located in the third region 23. The check valve 51 is located in the valve body mounting cavity 35 and can move along the direction from the second cavity 352 to the first cavity 351. One end of the check valve 51 passes through the first cavity 351 and is connected to the counterweight 52, and this end seals the first cavity 351. When the kettle is in an abnormal tilting state, the other end of the check valve 51 moves along the direction from the second cavity 352 to the first cavity 351 under the action of the counterweight 52 to the second cavity 352 to seal the second cavity 352, and the steam passage 34 is closed.

[0101] In this embodiment, the counterweight 52 and the check valve 51 are connected by screws, and the end of the check valve 51 away from the counterweight 52 is provided with a check valve sealing ring.

[0102] When the kettle is in the upright boiling state, the counterweight 52 contacts the top plane of the bracket 3 due to its own weight, and there is a gap between the lower end face of the stop valve 51 and the valve body mounting cavity 35. The steam channel 34 is in a naturally open state, and the steam generated in the kettle passes through the second area 22 and the valve body mounting cavity 35 from the steam inlet 25, and finally flows smoothly out from the steam outlet 32. The steam channel 34 is open throughout the process, maintaining normal steam circulation.

[0103] However, in the event of an unexpected tipping of the kettle, the counterweight 52 is instantly subjected to the combined forces of gravity and inertia, moving rapidly along the path from the second chamber 352 to the first chamber 351, causing the check valve 51 to move synchronously and quickly. The other end of the check valve 51 moves to the second chamber 352, precisely sealing the second chamber 352, cutting off the path of steam flow to the steam outlet 32, and closing the steam passage 34 as quickly as possible to prevent water leakage from the steam passage 34.

[0104] As an optional embodiment, as shown in FIG11, the check valve 51 includes a valve body 511 and a housing 512. One end of the valve body 511 is connected to the counterweight 52. The housing 512 has a bowl-shaped structure and one end is connected to the other end of the valve body 511. The other end of the housing 512 extends outward along its outer periphery to form a skirt 513. The skirt 513 is used to follow the valve body 511 as it moves along the direction from the second cavity 352 to the first cavity 351, and moves to the second cavity 352 to close the second cavity 352.

[0105] In this embodiment, when the kettle is boiling water upright, a gap is left between the shell 512 and the second cavity opening 352 to keep the steam passage 34 unobstructed and allow steam to be discharged normally. When the kettle is tilted, the pressure generated by the hot water and steam acts on the shell 512, while the counterweight 52 drives the check valve 51 to move. The skirt 513 is used to better fit around the second cavity opening 352 to seal the steam passage 34.

[0106] As an optional embodiment, as shown in FIG11, the valve body mounting cavity 35 is provided with a stepped structure, and the outer peripheral wall of the housing 512 is provided with a limiting bone 514. The limiting bone 514 is used to limit the range of movement of the housing 512 in the valve body mounting cavity 35 and prevent the housing 512 from tilting in the valve body mounting cavity 35 when it moves.

[0107] In this embodiment, the limiting bone 514 effectively prevents the housing 512 from moving out of its effective working range due to excessive displacement, ensuring that the check valve 51 always operates on the correct track. In addition, the limiting bone 514 can also prevent the valve body 511 from having too large a contact area and friction with the inner wall of the valve body mounting cavity 35, ensuring that the check valve 51 can move smoothly.

[0108] On the other hand, the limiting bone 514 ensures that the stop valve 51 will not tilt in the valve body mounting cavity 35, preventing poor sealing caused by tilting, and ensuring that the skirt 513 can seal the second cavity 352.

[0109] As an optional embodiment, as shown in FIG1, the bottom cover 2 includes a first side and a second side disposed opposite to each other. The first side and the second side of the bottom cover 2 correspond to the first side and the second side of the bracket 3, respectively. The steam inlet 25 is opened on the cover portion of the bottom cover 2 near its first side.

[0110] This application specifies that a steam inlet 25 is opened on the first side of the bottom cover 2, which corresponds to the first side of the bracket 3. This allows steam to enter from the steam inlet 25 of the bottom cover 2 and flow precisely into the corresponding area separated by the bracket 3, and then flow to the steam outlet 32. This optimizes the steam flow path, reduces turbulence and energy loss of steam in the lid assembly, improves the efficiency of steam discharge, ensures that steam can be smoothly discharged from the kettle, and guarantees the normal operation of the water boiling process.

[0111] As an optional embodiment, as shown in FIG11, the counterweight 52 includes a large-diameter end and a small-diameter end, the small-diameter end is connected to the valve body 511, and the center of gravity of the counterweight 52 is close to the large-diameter end.

[0112] In this embodiment, the counterweight 52 adopts an inverted conical structure and is preferably made of stainless steel or other high-density materials. During installation, the smaller diameter end faces downward, and it is fixed to the check valve 51 by screws through the screw hole in its center. Since the center of gravity is located at the larger diameter end, it can be more sensitive to the effects of gravity and inertia when the state of the kettle changes.

[0113] When the kettle tipped over, the center of gravity of the large-diameter end caused the counterweight 52 to move rapidly under the action of gravity and inertia, providing the power basis for the subsequent action of the check valve 51.

[0114] The purpose of this application is to provide a kettle, as shown in FIG15, including a kettle body 6 and the aforementioned kettle lid assembly, wherein the kettle lid assembly is detachably installed on the kettle body 6.

[0115] In this embodiment, during the assembly of the kettle, the lid assembly is detachably connected to the kettle body 6. When it is necessary to clean, maintain, or replace parts of the lid assembly, the user can easily detach the lid assembly from the kettle body 6, making the operation convenient and efficient.

[0116] This application combines the aforementioned lid assembly with the kettle body 6 to form a kettle. The lid assembly is detachable and easy to install, making it convenient for users to use and clean. At the same time, the functions of the lid assembly, such as anti-overflow and water flow control, are reflected in the kettle as a whole product, improving the practicality and user experience of the kettle.

[0117] In one embodiment, as shown in FIG14, the bottom cover 2 of the lid assembly is provided with a lid sealing ring 64 on the side near the body 6. After the lid assembly and the body 6 are assembled, the lid sealing ring 64 fits tightly against the wall of the water-containing cavity inside the body 6.

[0118] Whether the kettle is stationary, pouring water, or boiling water, the kettle lid sealing ring 64 can effectively seal the water-containing cavity inside the kettle body 6, preventing water from flowing out from the gap between the kettle lid assembly and the kettle body 6, and ensuring the sealing of the kettle body 6.

[0119] In another embodiment, as shown in Figures 7 and 14, the top cover 1 is provided with a cover lock 71 and a cover lock spring 72. The cover lock 71 passes through the cover lock mounting hole in the bottom cover 2 and tightly fixes the lid assembly to the mouth of the pot body 6, ensuring that the lid and the pot body 6 are firmly connected and the liquid inside the pot will not leak from the connection.

[0120] When it is necessary to open the lid assembly from the body 6, the user presses the lid lock 71 towards the center of the top cover 1. The lid lock spring 72 is compressed, and the lid lock 71 disengages from the fixed position at the mouth of the pot, making it easy to remove the lid assembly from the mouth of the pot.

[0121] As an optional embodiment, as shown in FIG16, the kettle body 6 is provided with a handle 61 and a steam outlet channel 63. The handle 61 is provided with a connecting cavity 62. One end of the connecting cavity 62 is connected to the steam outlet 32, and the other end is connected to one end of the steam outlet channel 63.

[0122] In this embodiment, during the boiling process, the boiling water in the kettle body 6 generates a large amount of steam. After the steam is orderly discharged through the steam outlet 32 ​​of the kettle lid assembly, it smoothly enters the connecting cavity 62 in the handle 61 of the kettle body 6. The steam flows along the connecting cavity 62 to the steam outlet channel 63 and is finally smoothly discharged from the kettle body 6 through the steam outlet channel 63.

[0123] This application has carefully planned a reasonable path for steam discharge, effectively avoiding the disorderly accumulation of steam in the kettle body 6. This not only ensures the safety of users and prevents the potential danger of steam burns, but also further optimizes the steam discharge process, making the overall function of the kettle more complete and bringing users a better user experience.

[0124] When this application is applied, as shown in Figures 1-4 and 16-17, when boiling water, the water in the kettle body 6 gradually heats up and boils under the action of the heating source. The generated steam enters the second area 22 from the steam inlet 25, and then exits from the steam outlet 32 ​​through the valve body mounting cavity 35 on the bracket 3. Subsequently, it is orderly discharged through the connecting cavity 62 in the handle 61 of the kettle body 6 and the steam outlet channel 63.

[0125] At this time, the first valve assembly 4 closes the inlet 24 and the outlet 33, effectively preventing hot water from overflowing unexpectedly. The second valve assembly 5 keeps the steam outlet 32 ​​open to ensure normal steam discharge and maintain the stable operation of the boiling process.

[0126] When pouring water, the user presses the water outlet button 42 as needed. The water outlet button 42 overcomes the resistance of the reset part 44 and moves slowly downward. During this process, the button drives the push rod 43 connected to it to move downward in sync. The other end of the push rod 43 then disengages from the water inlet 24, the water outlet channel 33 opens, and water flows freely from the water outlet 31.

[0127] At the same time, the water dispensing button 42 moves to a specific position, precisely engaging with the door lock switch 41. The door lock switch 41 firmly locks the water dispensing button 42, keeping it securely pressed. In this way, the user can easily and continuously pour water without having to hold down the button, making operation more convenient.

[0128] During the water pouring process, the second valve assembly 5 maintains the original state of the steam outlet 32 ​​to ensure normal steam discharge.

[0129] If the kettle accidentally tipes over while boiling water, the pressure from the hot water and steam acts on the casing 512. Simultaneously, the counterweight 52 is instantly subjected to the combined force of gravity and inertia, moving rapidly along the direction from the second chamber 352 to the first chamber 351, causing the check valve 51 to move synchronously and quickly. The other end of the check valve 51 moves to the second chamber 352, precisely sealing the second chamber 352, cutting off the path of steam flow to the steam outlet 32, and closing the steam passage 34 as quickly as possible to prevent water leakage from the steam passage 34.

[0130] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
