On the other hand, there are also some anti-overflow electric kettles, which are provided with multiple valves in the anti-overflow structure, which means complex assembly of parts and cumbersome operation.

[0003] For example, the Chinese utility model patent with the publication number CN218978600U discloses an electric kettle with anti-overflow function, which includes a kettle body and a kettle cover. The kettle cover is provided with a steam outlet, a first steam outlet channel, a second steam outlet channel, and two steam inlets. One end of the first steam outlet channel and the second steam outlet channel is connected to the steam outlet. The other end of the first steam outlet channel is connected to one steam inlet, and the other end of the second steam outlet channel is connected to the other steam inlet. The two steam inlets are symmetrically arranged on both sides of the line between the handle and the steam outlet. An anti-overflow valve is also provided. The entire structure is extremely complex and high in cost, and has a high rate of defects in production. Moreover, the conditions for triggering the anti-overflow valve are too complex to ensure that the water in the kettle body does not overflow when the kettle is poured. SUMMARY

[0065] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the application and, together with the general description of the application given above, and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0066] These and other features, aspects, and advantages of the present application will become better understood with reference to the following description and appended claims, taken in conjunction with the accompanying drawings.

[0067] It is also to be understood that even though a number of specific embodiments of the present application have been described herein, many other modifications and variations from these preferred designs are possible in light of this disclosure.

[0068] The above and other aspects, features, and advantages of the present application will become more apparent with reference to the following description taken in conjunction with the accompanying drawings, in which:

[0069] Specific embodiments of the present application are described herein below with reference to the accompanying drawings; however, it is to be understood that the application is not limited to the precise embodiments and that various modifications and changes can be made thereto by those skilled in the art. No limitation is intended to the details of construction or design herein shown, other than as described in the claims.

[0070] The specification can use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which can refer to one or more embodiments of the application.

[0071] One kettle cover assembly of the embodiments of the present application, as shown in Figure 1 and Figure 14 , comprises a top cover 1, a bottom cover 2, a support 3, a first valve assembly 4 and a second valve assembly 5.

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

[0073] Among them, a plurality of steam inlets 25 are arranged on the bottom cover 2, which facilitates the smooth entry of steam into the cavity during the boiling process. A condensate backflow hole is formed in the middle of the bottom cover 2, which provides a backflow path for the condensate after the steam is liquefied by cold water, avoiding water accumulation.

[0074] As shown in Figure 1 , the support 3 is arranged in the cavity and connected with the bottom cover 2, and the support 3 divides the cavity into a first area 21, a second area 22 and a third area 23 which are independent of each other. The support 3 comprises a first side and a second side arranged oppositely, the water outlet 31 is arranged on the first side, and the steam outlet 32 is arranged on the second side. The water inlet 24 and the water outlet 31 are both communicated with the first area 21 to form a water outlet channel 33, and the steam inlet 25 and the steam outlet 32 are both communicated with the second area 22 to form a steam channel 34.

[0075] The first valve assembly 4 is arranged on the first side of the support 3, which is used to control the opening and closing of the water inlet 24, so as to close the water inlet 24 when the kettle is in a boiling state, so as to close the water outlet channel 33, and to open the water inlet 24 when the kettle is in a pouring state, so as to open the water outlet channel 33.

[0076] The second valve assembly 5 is arranged on the second side of the support 3, which is used to control the opening and closing of the steam outlet 32, so as to open the steam outlet 32 when the kettle is in a boiling state, so as to open the steam channel 34, and to close the steam outlet 32 when the kettle is in an abnormal pouring state, so as to close the steam channel 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] like Figures 1-4 As shown, 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, such as Figure 14 As shown, the bottom cover 2 has an "∞" shaped mounting groove, 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, such as Figures 1-4 and Figure 14As shown, the first valve assembly 4 comprises 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 arranged in the third area 23 and connected with the support 3. The water outlet button 42 is movably arranged on the top cover 1, and the top cover 1 is provided with a water outlet button mounting hole. The push rod 43 is arranged in the first area 21, and one end of the push rod 43 can extend into the third area 23 through the support 3 and is connected with the water outlet button 42. The reset member 44 is arranged between the water outlet button 42 and the support 3, and is used to apply an upward movement force to the water outlet button 42 to reset it. The reset member 44 can be a spring.

[0085] When the water outlet button 42 is pressed downward, the water outlet button 42 moves downward to drive the push rod 43 to move downward, so that the other end of the push rod 43 is separated from the water inlet 24, the water outlet channel 33 is opened, and the water outlet button 42 is clamped 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 downward again, the water outlet button 42 is separated from the door lock switch 41 to release the locking of the water outlet button 42 by the door lock switch 41, so that the water outlet button 42 and the push rod 43 move upward to reset under the action of the reset member 44, the other end of the push rod 43 closes the water inlet 24, and the water outlet channel 33 is closed.

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

[0088] When the user presses the water outlet button 42 downward, the water outlet button 42 overcomes the resistance of the reset member 44 and slowly moves downward, in the process, the water outlet button 42 drives the push rod 43 connected therewith to move downward synchronously, the other end of the push rod 43 is separated from the water inlet 24, the water outlet channel 33 is opened, and water has the condition to flow out.

[0089] At the same time, the water outlet button 42 moves to a specific position and is tightly clamped with the door lock switch 41, the door lock switch 41 firmly locks the water outlet button 42 to keep it in the pressed state. In this way, the user can easily continue to pour water without pressing the water outlet button 42 all the time, and the operation is more convenient.

[0090] When the pouring operation is to be stopped after the water is poured, the user presses the water outlet button 42 downward again, the locking between the water outlet button 42 and the door lock switch 41 is released, and the water outlet button 42 and the push rod 43 are quickly reset upward under the action of the reset member 44, the push rod 43 re-precisely seals the water inlet 24, the water outlet channel 33 is immediately closed, and the water stops flowing out.

[0091] With the cooperation of the door lock switch 41, the water outlet button 42, the push rod 43, and the reset member 44, the downward pressing of the water outlet button 42 can drive the push rod 43 to move to open the water outlet channel 33, and the button can be clamped with the door lock switch 41 to be locked in the pressed state, facilitating continuous pouring operation; the button can be pressed again to release the locking, and the button and the push rod 43 are reset to close the water outlet channel 33 under the action of the reset member 44, which is simple and reliable in operation, and is more convenient and easy to use than the complex and tedious multi-valve operation mode.

[0092] As an optional embodiment, as shown in Figure 2 and Figure 14 , the push rod 43 comprises a sealing part and two rod parts.

[0093] The sealing part is arranged in the first area 21, one end of the two rod parts is connected to the sealing part, and the other end of the two rod parts penetrates through the bracket 3 and is connected to the water outlet button 42, respectively, and the reset member 44 is sleeved on the two rod parts.

[0094] In this embodiment, the sealing part is arranged in the first area 21, and a sealing ring is arranged on the sealing part to seal the gap between the sealing part and the water inlet 24, so that excellent sealing can be achieved when the water inlet 24 is closed.

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

[0096] When the water outlet button 42 is actuated by external force, the sealing part can be stably and efficiently driven to move, and the opening and closing of the water inlet 24 can be accurately realized; the reset member 44 is sleeved on the two rod parts, and provides a force for the reset of the water outlet button 42 during the reciprocating movement of the push rod 43, so as to ensure smooth operation of the entire system.

[0097] As an optional embodiment, as shown in Figures 8-9 , a valve body mounting cavity 35 is arranged on the bracket 3 near the steam outlet 32, the valve body mounting cavity 35 communicates with the second area 22 and the steam outlet 32, steam enters the second area 22 from the steam inlet 25, and flows to the steam outlet 32 through the valve body mounting cavity 35.

[0098] In the embodiment, after the steam from the steam inlet 25 of the bottom cover 2 smoothly enters the second area 22, it flows to the steam outlet 32 through the valve body mounting cavity 35, so that the steam can pass through the established route in an orderly manner during the whole process from entering to discharging, completely eliminating the hidden trouble of steam turbulence or blockage, and providing strong support for the efficient operation of the kettle.

[0099] As an optional embodiment, as shown in Figure 9 and Figure 10 , the cavity wall of the valve body mounting cavity 35 is provided with a first cavity opening 351 and a second cavity opening 352, the first cavity opening 351 is in communication with the third area 23, and the second cavity opening 352 is in communication with the second area 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 arranged in the third area 23, the check valve 51 is arranged in the valve body mounting cavity 35 and can move in the direction from the second cavity opening 352 to the first cavity opening 351, one end of the check valve 51 penetrates the first cavity opening 351 and is connected with the counterweight 52, and seals the first cavity opening 351, the other end of the check valve 51 moves to the second cavity opening 352 in the direction from the second cavity opening 352 to the first cavity opening 351 under the action of the counterweight 52 when the kettle is in an abnormal tilting state, so as to seal the second cavity opening 352, and the steam passage 34 is closed.

[0101] In the 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 a straight-up boiling state, the counterweight 52 contacts the top plane of the support 3 due to its own gravity, a gap is left between the lower end surface of the check valve 51 and the valve body mounting cavity 35, the steam passage 34 is in a naturally open state, the steam generated in the kettle sequentially passes through the second area 22, the valve body mounting cavity 35, and finally smoothly discharges from the steam outlet 32, the steam passage 34 is open throughout, and normal steam circulation is maintained.

[0103] However, once the kettle encounters an abnormal tilting emergency, the counterweight 52 is instantly subjected to the dual forces of gravity and inertia, and moves rapidly in the direction from the second cavity opening 352 to the first cavity opening 351, driving the check valve 51 to move synchronously and rapidly. The other end of the check valve 51 moves to the second cavity opening 352, accurately seals the second cavity opening 352, cuts off the path of the steam flowing to the steam outlet 32, closes the steam passage 34 at the fastest speed, and prevents water from leaking from the steam passage 34.

[0104] As an optional embodiment, as shown inFigure 11 As shown, the flow stop valve 51 comprises a valve body 511 and a housing 512. One end of the valve body 511 is connected with the counterweight 52, and the housing 512 is in the form of a bowl structure, and one end of the housing 512 is connected with the other end of the valve body 511. The other end of the housing 512 extends outward along the outer periphery thereof to form a skirt 513, which is used to follow the movement of the valve body 511 in the direction from the second cavity opening 352 to the first cavity opening 351, and to move to the second cavity opening 352 to close the second cavity opening 352.

[0105] In the present embodiment, the housing 512 leaves a gap between the second cavity opening 352 when the kettle is normally upright for boiling, so that the steam passage 34 remains unobstructed, and steam can be normally discharged. When the kettle is tilted, the pressure generated by hot water and steam acts on the housing 512, and the counterweight 52 drives the flow stop valve 51 to move, and the skirt 513 is used to better fit the periphery of the second cavity opening 352 to seal the steam passage 34.

[0106] As an optional embodiment, as shown in Figure 11 As shown, a step structure is provided in the valve body mounting cavity 35, and a limiting rib 514 is provided on the outer peripheral wall of the housing 512. The limiting rib 514 is used to limit the movement range of the housing 512 in the valve body mounting cavity 35, and to prevent the housing 512 from tilting in the valve body mounting cavity 35 when it moves.

[0107] In the present embodiment, the limiting rib 514 effectively prevents the housing 512 from being out of the effective working range due to excessive displacement, ensuring that the flow stop valve 51 always operates on the right track. In addition, the limiting rib 514 can also avoid excessive contact area and friction between the valve body 511 and the inner wall of the valve body mounting cavity 35, ensuring that the flow stop valve 51 can move smoothly.

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

[0109] As an optional embodiment, as shown in Figure 1 As shown, the bottom cover 2 comprises a first side and a second side arranged 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 support 3 respectively. The steam inlet 25 is provided on the cover body portion of the bottom cover 2 close to the first side thereof.

[0110] The first side of the bottom cover 2 is provided with a steam inlet 25, which corresponds to the first side of the support 3, so that the steam entering the steam inlet 25 of the bottom cover 2 can flow into the corresponding area separated by the support 3 and then flow to the steam outlet 32, thereby optimizing the flow path of the steam, reducing the turbulence and energy loss of the steam in the kettle cover assembly, improving the efficiency of steam discharge, ensuring that the steam can be smoothly discharged from the kettle, and ensuring the normal operation of the water boiling process.

[0111] As an optional embodiment, as shown in Figure 11 The counterweight 52 includes a large-diameter end and a small-diameter end, the small-diameter end is connected with 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 is in an inverted conical structure and is preferably made of stainless steel or other materials with high density. When installed, the small-diameter end faces downward, and the screw hole in the center is fixed on the stop valve 51 by a screw. Since the center of gravity is at the large-diameter end, the counterweight 52 can be more sensitive to the influence of gravity and inertia when the state of the kettle changes.

[0113] When the kettle is tilted, the center of gravity of the large-diameter end makes the counterweight 52 move quickly under the action of gravity and inertia, providing a power basis for driving the stop valve 51 to act subsequently.

[0114] The purpose of the embodiment of the present application is to provide a kettle, as shown in Figure 15 The kettle includes a kettle body 6 and the kettle cover assembly described above, and the kettle cover assembly is detachably installed on the kettle body 6.

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

[0116] The kettle cover assembly with various beneficial functions described above is combined with the kettle body 6 to form a kettle, and the kettle cover assembly is detachably installed, which is convenient for users to use and clean, and can also make the functions of the kettle cover assembly, such as spilling prevention and water discharge control, be embodied on the whole kettle product, thereby improving the practicality and user experience of the kettle product.

[0117] In an embodiment, as shown in Figure 14 The bottom cover 2 of the kettle cover assembly is provided with a kettle cover sealing ring 64 on one side close to the kettle body 6, and the kettle cover sealing ring 64 tightly contacts the wall surface of the water-containing cavity in the kettle body 6 after the kettle cover assembly and the kettle body 6 are assembled.

[0118] No matter the kettle is in a variety of states such as static, pouring water or boiling water, the sealing ring 64 of the kettle cover can effectively seal the water cavity in the kettle body 6, prevent water from flowing out of the gap between the kettle cover assembly and the kettle body 6, and ensure the sealing of the kettle body 6.

[0119] In another embodiment, as shown in Figure 7 and Figure 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 of the bottom cover 2 to tightly fix the kettle cover assembly at the kettle opening of the kettle body 6, ensuring that the kettle cover is stably connected with the kettle body 6 and that the liquid in the kettle does not leak from the connection.

[0120] When it is necessary to open the kettle cover assembly from the kettle body 6, the user presses the cover lock 71 at the center of the top cover 1, the cover lock spring 72 is compressed, and the cover lock 71 is released from the fixed position of the kettle opening, so that the kettle cover assembly can be easily removed from the kettle opening.

[0121] As an optional embodiment, as shown in Figure 16 , the kettle body 6 is provided with a handle 61 and an air outlet passage 63. The handle 61 is provided with a connecting cavity 62. One end of the connecting cavity 62 is in communication with the steam outlet 32, and the other end is in communication with one end of the air outlet passage 63.

[0122] In this embodiment, during the boiling process, a large amount of steam is generated by the boiling water in the kettle body 6. After the steam is orderly discharged through the steam outlet 32 of the kettle cover 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 air outlet passage 63, and is finally smoothly discharged from the kettle body 6 through the air outlet passage 63.

[0123] The application carefully plans a reasonable path for steam discharge, effectively avoids the disordered accumulation of steam in the kettle body 6, not only practically guarantees the safety of the user and prevents the potential danger of steam scalding, but also further optimizes the steam discharge process, so that the overall function of the kettle is more perfect, and the user has a better use experience.

[0124] In application, as shown in Figures 1-4 , Figures 16-17 , during boiling, the water in the kettle body 6 is gradually heated and boiled under the action of the heating source. The generated steam enters the second area 22 from the steam inlet 25, then is discharged from the steam outlet 32 through the valve body mounting cavity 35 on the support 3, and then is orderly discharged through the connecting cavity 62 in the handle 61 of the kettle body 6 and the air outlet passage 63.

[0125] At this time, the first valve assembly 4 closes the water inlet 24, and the water outlet passage 33 is closed, effectively preventing the hot water from accidentally overflowing. The second valve assembly 5 keeps the steam outlet 32 open, ensuring normal discharge of steam and maintaining stable progress of the boiling process.

[0126] When pouring water, the user presses the water outlet button 42 according to the needs, the water outlet button 42 overcomes the resistance of the reset member 44, slowly moves downward, in the process, the button drives the push rod 43 connected therewith to move downward synchronously, the other end of the push rod 43 is separated from the water inlet 24, the water outlet channel 33 is opened, and water is poured out from the water outlet 31.

[0127] At the same time, the water outlet button 42 moves to a specific position and is tightly clamped with the door lock switch 41, the door lock switch 41 firmly locks the water outlet button 42, so that it is stably kept in the pressed state. In this way, the user can easily continue to pour water without pressing the button all the time, and the operation is more convenient.

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

[0129] If the kettle is accidentally poured when boiling water, the pressure generated by hot water and steam acts on the shell 512, and at the same time the counterweight 52 is instantaneously subjected to the dual forces of gravity and inertia, and moves rapidly along the direction from the second cavity opening 352 to the first cavity opening 351, driving the stop valve 51 to move synchronously at a high speed. The other end of the stop valve 51 moves to the second cavity opening 352, precisely seals the second cavity opening 352, cuts off the path of steam flowing to the steam outlet 32, closes the steam channel 34 at the fastest speed, and prevents water from leaking from the steam channel 34.

[0130] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also regarded as falling within the protection scope of the present application.
