Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a container lid and a liquid heating container. Background Technology

[0002] A liquid heating container includes a container body and a container lid. The lid typically houses a water-sealing assembly and a switching assembly. The switching assembly drives the water-sealing assembly to move within the lid, opening or closing the water outlet channel. When the water-sealing assembly closes the outlet channel, it prevents water from flowing out of the container through the lid, thus achieving the anti-tipping function of the liquid heating container.

[0003] However, the existing switch components still have the problem of complex structure and inconvenient installation, which affects the installation efficiency of the container cover. Utility Model Content

[0004] This application provides a container lid and a liquid heating container, which can solve the problem of complex structure of switch components in the prior art.

[0005] This application provides a container lid, comprising: a lid body having a water outlet channel, the lid body further comprising an external toothed portion and a sliding groove; a water sealing assembly slidably mounted in the lid body; and a switch assembly mounted in the lid body, the switch assembly being used to drive the water sealing assembly to slide within the lid body, thereby enabling the water sealing assembly to open or close the water outlet channel; the switch assembly comprising a limiting member having an upper toothed portion and a lower toothed portion, the upper toothed portion being used to slidely engage with the external toothed portion, thereby enabling the limiting member to rotate relative to the lid body; the lower toothed portion being used to slidely engage with the sliding groove, the sliding groove comprising a stop groove, wherein when the limiting member rotates to the point where the lower toothed portion engages with the stop groove, the water sealing assembly can open the water outlet channel; and when the limiting member rotates to the point where the lower toothed portion disengages from the stop groove, the water sealing assembly can close the water outlet channel.

[0006] In the above scheme, when the limiting member moves downward under pressure, the tip of the upper tooth can slide along the tooth surface of the outer tooth, allowing the limiting member to rotate relative to the cover. The slide groove is equipped with a stop groove; during the rotation of the limiting member, the lower tooth can engage with the stop groove, and the water sealing component, under the action of the limiting member, keeps the water outlet channel open. That is, the engagement of the lower tooth with the stop groove enables the water sealing component to be locked, eliminating the need for continuous downward pressure on the limiting member when emptying water, thus improving the user experience. After emptying water, if the user needs to close the water outlet channel, the limiting member can be driven again. The engagement of the upper and outer teeth causes the limiting member to rotate relative to the cover again, disengaging the lower tooth from the stop groove and releasing it from engagement. At this point, the cover no longer limits the switch assembly, allowing the switch assembly to move the water sealing component upward, thereby closing the water outlet channel.

[0007] The container lid provided in this application embodiment has the external toothed part that cooperates with the upper toothed part to drive the rotation of the limiting member, and the sliding groove that cooperates with the lower toothed part to limit the continued movement of the limiting member, both set inside the lid body. There is no need to set separate parts to drive the rotation of the limiting member, which can save the number of parts of the container lid, thereby reducing the manufacturing cost of the container lid and improving the assembly efficiency of the container lid.

[0008] In one possible design, the cover is provided with a mounting hole, the limiting member is movably mounted in the mounting hole, and the sliding groove is provided on the inner wall of the mounting hole; the sliding groove also includes a plurality of limiting grooves, the limiting grooves extending along the height direction of the container cover, the plurality of limiting grooves being spaced apart on the inner wall of the mounting hole, and a stop groove being provided between any two adjacent limiting grooves, the stop groove being connected to the two adjacent limiting grooves respectively; the switch assembly also includes a button, the lower tooth being used to slide along the limiting groove into the stop groove under the drive of the button, so as to engage with the stop groove; the lower tooth is also used to slide along the stop groove into another adjacent limiting groove under the drive of the button, so as to disengage from the stop groove.

[0009] In the above scheme, when the limiting member is pressed by the button and moves downward, the lower tooth can slide downward along the limiting groove, and the upper tooth can gradually approach the outer tooth. When the lower tooth slides to the position where the bottom of the limiting groove connects with the stop groove, the tip of the upper tooth can contact the tooth surface of the outer tooth, so that the limiting member can rotate relative to the cover while moving downward, thereby allowing the lower tooth to slide into the stop groove connected to the limiting groove. At this time, the pressing of the limiting member is stopped, and an upward force is applied to the limiting member. The limiting member can slide upward along the stop groove and form a locking fixation with the stop groove, thereby keeping the water outlet channel in the open state. When the water outlet is closed, the user can press down the limiting member again. When the lower tooth slides to the bottom of the stop groove and connects with another limiting groove, the tip of the upper tooth can disengage from the outer tooth and form a sliding engagement, driving the limiting member to continue rotating relative to the cover. This allows the lower tooth to slide along the stop groove into another adjacent limiting groove, thus disengaging the lower tooth from the stop groove. At this point, stop pressing down the limiting member and apply an upward force to it. The limiting member can then move upward along the limiting groove, thereby enabling the switch assembly to drive the sealing assembly to close the water outlet.

[0010] In one possible design, the external toothed portion is disposed on the outer wall of the mounting hole; the limiting member is provided with a platform portion, and the upper toothed portion is disposed on the platform portion; the button abuts against the platform portion along the height direction of the container lid to drive the limiting member to move within the mounting hole along the height direction of the container lid, so that the upper toothed portion can slide with the external toothed portion, and the lower toothed portion can slide with the groove.

[0011] In the above solution, when the limiting member has a platform portion, even if the button or the limiting member shifts, it can ensure that the abutting part and the limiting member have sufficient contact area, thereby improving the reliability of the button driving the limiting member to move. Moreover, setting the external teeth on the outer wall of the mounting hole and the upper teeth on the platform portion ensures that the upper teeth and the external teeth are positioned in correspondence, and also helps to save space inside the lid, making it easier to reduce the volume of the container lid.

[0012] In one possible design, the button is provided with a protrusion; the cover is provided with a guide groove extending along the height direction of the container cover, and the protrusion is slidably connected to the guide groove.

[0013] In the above solution, as the button moves up and down along the height of the container lid, the guide groove can form a guiding engagement with the protrusion, thereby improving the movement stability of the button. In addition, the guide groove can also limit the protrusion to prevent the button from rotating relative to the lid.

[0014] In one possible design, the switch assembly further includes a reset spring, the cover is provided with a spring mounting groove, one end of the reset spring abuts against the button, and the other end abuts against the bottom wall of the spring mounting groove.

[0015] In the above solution, the return spring enables the button to automatically reset and also provides a certain supporting force, which helps improve the button's movement stability. By setting a spring mounting groove on the cover, the stability of the return spring can be improved, ensuring that the return spring can stably support the button.

[0016] In one possible design, the water sealing assembly includes a water sealing valve that is slidably connected to the mounting hole and has a connection hole; the button is provided with a connecting rod, at least a portion of which extends into the connection hole, and the side wall of the connecting rod is engaged and fixed with the side wall of the connection hole.

[0017] In the above solution, the side wall of the connecting rod is snapped into the side wall of the connecting hole to ensure that the sealing valve moves synchronously with the button, which helps improve the stability of the sealing valve's movement. The snap-fit ​​structure is relatively simple, saves parts compared to bolted connections, and is also easier to assemble, thus improving the assembly efficiency of the container cap.

[0018] In one possible design, the sealing valve is provided with a stepped portion; the limiting member is sleeved on the sealing valve, and the bottom end of the limiting member is in a limiting fit with the stepped portion along the height direction of the container lid.

[0019] In the above scheme, when the user presses the button to drive the limiting component downward, not only does the button drive the sealing valve downward, but the limiting component also applies a downward force to the step, ensuring that the sealing valve can quickly open the water outlet channel. During the reset process of the sealing assembly, the sealing valve can drive the limiting component to move upward synchronously through the step, thereby achieving synchronous reset of the sealing assembly and the switch assembly.

[0020] In one possible design, the bottom of the cover is provided with a water passage hole, which communicates with the water outlet channel; the end of the water sealing valve near the water passage hole is provided with a sealing part, and the water sealing assembly also includes a water sealing ring, which is sleeved on the sealing part; when the water sealing valve slides along the mounting hole until the water sealing ring blocks the water passage hole, the water outlet channel is closed; when the water sealing valve slides along the mounting hole until the water sealing ring moves away from the water passage hole, the water outlet channel is opened.

[0021] In the above solution, when the sealing valve slides along the mounting hole to the first state, the sealing ring moves away from the water inlet, thus opening the water inlet and opening the water outlet channel. At this time, if the user tilts the liquid heating container, the liquid inside the container can flow to the outside through the water inlet and the water outlet channel, realizing the water outlet function of the liquid heating container. When the sealing valve slides along the mounting hole to the second state, the upper surface of the sealing ring can closely contact the edge of the water inlet, thus blocking the water inlet and closing the water outlet channel. At this time, even if the liquid heating container tilts, the liquid inside the container will not flow out through the water outlet channel, realizing the anti-tipping function of the liquid heating container and improving the user experience.

[0022] In one possible design, the water sealing assembly further includes a water-proof ring fitted onto the water sealing valve. When the water sealing valve slides along the mounting hole, the water-proof ring is used to seal against the mounting hole.

[0023] In the above scheme, as the sealing valve slides along the mounting hole, the water-sealing ring moves synchronously with the sealing valve and maintains a sealed fit with the mounting hole, thereby preventing liquid or food in the container from entering the lid through the mounting hole.

[0024] A second aspect of this application provides a liquid heating container, including a container body and the container lid described above.

[0025] In the above solution, the container lid can achieve the anti-tipping function. Moreover, by setting external teeth and grooves on the lid body, the number of parts of the container lid can be reduced, thereby reducing the manufacturing cost of the liquid heating container and improving the assembly efficiency of the liquid heating container.

[0026] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0075] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0076] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0077] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0078] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0079] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0080] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0081] This application provides a container lid 10 for heating liquid containers, such as... Figure 1 As shown, the container lid 10 includes a lid body 1, a water sealing assembly 2, and a switch assembly 3. The water sealing assembly 2 and the switch assembly 3 are installed on the lid body 1. The lid body 1 has a water outlet channel 11 inside. The switch assembly 3 is used to drive the water sealing assembly 2 to move up and down along the height direction Z of the container lid 10, so that the water sealing assembly 2 can open or close the water outlet channel 11.

[0082] Specifically, the cover 1 also has a mounting hole 14, and the water sealing component 2 is slidably connected to the mounting hole 14. A water passage hole 17 is provided at the bottom of the cover 1, and the water passage hole 17 communicates with the water outlet channel 11. Combined with... Figure 2 As shown, the water sealing assembly 2 includes a water sealing valve 21 and a water sealing ring 22. A sealing portion 213 is provided at one end of the water sealing valve 21 near the water inlet 17. The sealing portion 213 extends radially (X) away from the center of the water sealing valve 21. The water sealing ring 22 is fitted onto the sealing portion 213. When the water sealing valve 21 slides along the mounting hole 14 to… Figure 3 In the first state, the water-sealing ring 22 is away from the water inlet 17, thereby opening the water inlet 17 and opening the water outlet channel 11. At this time, if the user pours liquid into the heating container, the liquid inside the container 20 can flow to the outside through the water inlet 17 and the water outlet channel 11 (e.g., ...). Figure 3 (As shown by the middle arrow), this enables the water outlet function of the liquid heating container. When the sealing valve 21 slides along the mounting hole 14 to... Figure 1 In the second state shown, the upper surface of the water sealing ring 22 can closely contact the edge of the water passage 17, thereby blocking the water passage 17 and keeping the water outlet channel 11 closed. At this time, even if the liquid heating container is tilted, the liquid in the container body 20 will not flow out through the water outlet channel 11, thus realizing the anti-tipping function of the liquid heating container and improving the user experience.

[0083] In one specific implementation, such as Figure 2 As shown, the water sealing assembly 2 also includes a water-proof ring 23, which is fitted onto the water sealing valve 21. As the water sealing valve 21 slides along the mounting hole 14, the water-proof ring 23 moves synchronously with it. The water-proof ring 23 has an annular sealing portion 231, which maintains a sealed fit with the mounting hole 14, thereby preventing liquid or food from entering the lid 1 through the mounting hole 14.

[0084] like Figure 1 As shown, the cover 1 includes at least an upper cover 101, a middle cover 102, and a lower cover 103. A mounting hole 14 is located on the middle cover 102, and a water passage hole 17 is located at the bottom of the lower cover 103. Figure 4 As shown, the cover 1 also includes a sealing ring 105. The middle cover 102 is provided with an annular groove 102a, and the sealing ring 105 is installed in the annular groove 102a to achieve a sealing fit between the upper cover 101 and the middle cover 102. The cover 1 also includes a cover sealing ring 106, which is sleeved on the bottom of the lower cover 103 to achieve a sealing fit between the container cover 10 and the container body 20.

[0085] like Figure 1 and Figure 5 As shown, the switch assembly 3 includes a limiting member 32, which is provided with an upper toothed portion 321 and a lower toothed portion 322. Combined with... Figure 6 and Figure 7As shown, the cover 1 is provided with an external toothed portion 12 and a sliding groove 13. During the process of the switch assembly 3 driving the water sealing assembly 2 to move downward to open the water outlet channel 11, the upper toothed portion 321 is used to slide and engage with the external toothed portion 12, and the lower toothed portion 322 is used to slide and engage with the sliding groove 13. Since both the upper toothed portion 321 and the external toothed portion 12 are sawtooth structures, when the limiting member 32 is pressed downward, the tooth tip of the upper toothed portion 321 can slide along the tooth surface of the external toothed portion 12, thereby allowing the limiting member 32 to rotate relative to the cover 1. The sliding groove 13 is provided with a stop groove 131. During the rotation of the limiting member 32, the lower toothed portion 322 can engage with the stop groove 131, and the water sealing assembly 2 can be maintained in the first state under the action of the limiting member 32, so that the water outlet channel 11 remains in the open state. The water sealing component 2 can be locked by the engagement of the lower tooth 322 with the stop groove 131. Users do not need to continuously push the limiting member 32 down when emptying water, improving the user experience. After emptying the water, if it is necessary to close the water outlet channel 11, the limiting member 32 can be driven again. The engagement of the upper tooth 321 with the outer tooth 12 causes the limiting member 32 to rotate relative to the cover 1 again, thereby disengaging the lower tooth 322 from the stop groove 131 and releasing it from engagement. At this point, the cover 1 no longer limits the switch component 3, and the switch component 3 can drive the water sealing component 2 upwards, thus closing the water outlet channel 11.

[0086] The container lid 10 provided in this application embodiment has the external tooth 12, which cooperates with the upper tooth 321 to drive the limit member 32 to rotate, and the sliding groove 13, which cooperates with the lower tooth 322 to limit the continued movement of the limit member 32, both disposed inside the lid body 1. There is no need to set up separate parts to drive the limit member 32 to rotate, which can save the number of parts of the container lid 10, thereby reducing the manufacturing cost of the container lid 10 and improving the assembly efficiency of the container lid 10.

[0087] In this embodiment, the external toothed portion 12 and the sliding groove 13 can be specifically disposed in the middle cover 102.

[0088] In one specific implementation, such as Figure 1 and Figure 6 As shown, the slide groove 13 can be disposed on the inner wall of the mounting hole 14, the limiting member 32 is movably installed in the mounting hole 14, and the external toothed part 12 is disposed on the outer wall of the mounting hole 14. Combined with... Figure 7 As shown, the slide 13 also includes multiple limiting grooves 132. The limiting grooves 132 extend along the height direction Z of the container cover 10. The multiple limiting grooves 132 are spaced apart on the inner wall of the mounting hole 14. A stop groove 131 is provided between any two adjacent limiting grooves 132. The stop groove 131 and the two adjacent limiting grooves 132 are respectively connected.

[0089] When the limiting member 32 is pressed downward, the lower tooth 322 can slide downward along the limiting groove 132, and the upper tooth 321 can gradually approach the outer tooth 12. When the lower tooth 322 slides to the position where the bottom of the limiting groove 132 connects with the stop groove 131, the tip of the upper tooth 321 can contact the tooth surface of the outer tooth 12, so that the limiting member 32 can rotate relative to the cover 1 while moving downward, thereby allowing the lower tooth 322 to slide into the stop groove 131 connected to the limiting groove 132. The stop groove 131 is a triangular structure recessed towards the top of the cover 1. At this time, when the pressure on the limiting member 32 is stopped and an upward force is applied to the limiting member 32, the limiting member 32 can slide upward along the stop groove 131 and form a locking and fixing with the triangular structure of the stop groove 131, thereby keeping the water outlet channel 11 in the open state.

[0090] When the water outlet channel 11 is closed, the engagement between the lower tooth 322 and the stop groove 131 needs to be released. The user can press down the limiting member 32 again. When the lower tooth 322 slides to the position where the bottom of the stop groove 131 is connected to another limiting groove 132, the tip of the upper tooth 321 can disengage from the outer tooth 12 and form a sliding engagement, so as to drive the limiting member 32 to continue to rotate relative to the cover 1. This allows the lower tooth 322 to slide along the stop groove 131 into the adjacent limiting groove 132, so as to release the engagement between the lower tooth 322 and the stop groove 131. At this time, stop pressing down the limiting member 32 and apply an upward force to the limiting member 32. The limiting member 32 can move upward along the limiting groove 132, so that the switch assembly 3 can drive the sealing assembly 2 to close the water outlet channel 11.

[0091] like Figure 1 As shown, the switch assembly 3 also includes a button 31, which the user can press down to drive the limiting member 32 to move downward. Specifically, the limiting member 32 is provided with a platform portion 323 extending outward along its radial direction X, and an upper toothed portion 321 is provided on the platform portion 323. Combined with... Figure 8As shown, the button 31 has a receiving space 313, and an abutment portion 314 is provided inside the receiving space 313. At least a portion of the platform portion 323 is located within the receiving space 313. The abutment portion 314 can abut against the platform portion 323 along the height direction Z of the container cover 10. The button 31 drives the limiting member 32 to move downward through the abutment portion 314, so that the upper tooth portion 321 can slide against the outer tooth portion 12, and the lower tooth portion 322 can slide against the slide groove 13. When the limiting member 32 is provided with an outwardly extending platform portion 323, even if the button 31 or the limiting member 32 is displaced, it can be ensured that the abutment portion 314 and the limiting member 32 have sufficient contact area, thereby improving the reliability of the button 31 driving the limiting member 32 to move. Furthermore, by placing the outer toothed portion 12 on the outer wall of the mounting hole 14 and placing the upper toothed portion 321 on the platform portion 323, it is possible to ensure that the upper toothed portion 321 corresponds to the outer toothed portion 12, which also helps to save space inside the cover 1 and makes it easier to reduce the volume of the container cover 10.

[0092] like Figure 1 As shown, the switch assembly 3 also includes a reset spring 33, which, in conjunction with... Figure 3 As shown, the cover 1 is also provided with a spring mounting groove 16. One end of the return spring 33 extends into the receiving space 313 and abuts against the button 31, while the other end abuts against the bottom wall of the spring mounting groove 16. The return spring 33 can realize the automatic reset of the button 31 and also provide a certain support force for the button 31, which is beneficial to improving the movement stability of the button 31. By providing a spring mounting groove 16 on the cover 1, the stability of the return spring 33 can be improved, ensuring that the return spring 33 can stably support the button 31.

[0093] In this embodiment, the spring mounting groove 16 may be specifically provided in the middle cover 102 and should be provided around the outside of the mounting hole 14.

[0094] In one specific implementation, such as Figure 8 As shown, the outer wall of button 31 is also provided with a protrusion 311, such as... Figure 6 As shown, the lid 1 is provided with a guide groove 15 extending along the height direction Z of the container lid 10, and the protrusion 311 is slidably connected to the guide groove 15. During the up-and-down movement of the button 31 along the height direction Z of the container lid 10, the guide groove 15 can form a guiding engagement with the protrusion 311, thereby improving the movement stability of the button 31. In addition, the guide groove 15 can also limit the protrusion 311 to prevent the button 31 from rotating relative to the lid 1.

[0095] Specifically, multiple spaced protrusions 311 can be provided on the outer wall of the button 31, and multiple guide grooves 15 can be provided on the cover 1 accordingly, which helps to improve the guiding and limiting effect of the guide grooves 15 on the button 31.

[0096] In this embodiment of the application, the guide groove 15 may be specifically disposed in the middle cover 102.

[0097] In one specific embodiment, the switch assembly 3 drives the movement of the water sealing assembly 2 via the button 31, such as... Figure 2 and Figure 5 As shown, the sealing valve 21 is provided with a connection hole 211, and the button 31 is provided with a connecting rod 312. At least a portion of the connecting rod 312 extends into the connection hole 211, and the side wall of the connecting rod 312 is engaged and fixed with the side wall of the connection hole 211, so that the sealing valve 21 can move synchronously with the button 31, which helps to improve the movement stability of the sealing valve 21.

[0098] Specifically, a snap-fit ​​protrusion 312a can be provided on one side wall of the connecting rod 312 and the side wall of the connecting hole 211, while a snap-fit ​​groove or snap-fit ​​hole 211a can be provided on the other side. The two are snap-fitted and fixed by the cooperation of the snap-fit ​​protrusion 312a and the groove, or by the cooperation of the snap-fit ​​protrusion 312a and the snap-fit ​​hole 211a. In this embodiment, the snap-fit ​​structure is relatively simple, which saves parts and facilitates assembly compared to the bolt connection method, thus improving the assembly efficiency of the container cover 10.

[0099] Furthermore, such as Figure 2 As shown, a water sealing valve 21 is also provided, which has a stepped portion 212. A limiting member 32 is sleeved on the water sealing valve 21, and the bottom end of the limiting member 32 can form a limiting fit with the stepped portion 212 along the height direction Z of the container cover 10.

[0100] Based on the above structure, the working process of the container cover 10 provided in this application embodiment is as follows: When opening the water outlet channel 11, the user presses down the button 31 to drive the limiting member 32 to move downward. The return spring 33 is gradually compressed. During this process, not only does the button 31 drive the sealing valve 21 to move downward, but the limiting member 32 can also apply a downward force to the step portion 212 to ensure that the sealing valve 21 can quickly open the water outlet channel 11. When the lower tooth portion 322 slides to the position where the bottom of the limiting groove 132 is connected to the stop groove 131, the tooth tip of the upper tooth portion 321 can contact the tooth surface of the outer tooth portion 12, so that the limiting member 32 can rotate relative to the cover body 1 while moving downward, thereby allowing the lower tooth portion 322 to slide into the stop groove 131 connected to the limiting groove 132. At this time, the user can stop pressing button 31. Under the action of its own restoring force, the return spring 33 can drive button 31 to move upward. Button 31 drives water sealing valve 21 to move upward synchronously. The limiting member 32 can also move upward synchronously under the action of step 212, so that the lower tooth 322 engages with stop groove 131 (return spring 33 is still in the compressed state). At this time, the limiting member 32 can restrict step 212 from continuing to move upward, so that water sealing valve 21 and button 31 remain in the current position, so that water outlet channel 11 can remain in the open state.

[0101] When the water outlet channel 11 is closed, the user can press the button 31 again to drive the limiting member 32 to move downward again. The return spring 33 is compressed again. When the lower tooth 322 slides to the position where the bottom of the stop groove 131 connects with another limiting groove 132, the tip of the upper tooth 321 can disengage from the outer tooth 12 and form a sliding engagement, so as to drive the limiting member 32 to continue rotating relative to the cover 1. This allows the lower tooth 322 to slide along the stop groove 131 into the adjacent limiting groove 132, and the lower tooth 322 and the stop groove 131 are disengaged. At this time, the user can stop pressing the button 31 again. Under the action of its own restoring force, the return spring 33 can drive the button 31 to move upward again. The button 31 drives the sealing valve 21 to move upward synchronously. The limiting member 32 also moves upward synchronously under the action of the step 212, which can complete the synchronous automatic reset of the switch assembly 3 and the sealing assembly 2, thereby realizing the closure of the water outlet channel 11.

[0102] This application also provides a liquid heating container, such as... Figure 1As shown, the liquid heating container includes a container body 20 and the aforementioned container lid 10, with the lid 10 mounted on the top of the container body 20. When a user uses the liquid heating container to drink water, they can press button 31 to open the water inlet 17, and then pour the liquid heating container, allowing the liquid inside the container body 20 to flow from the water inlet 17 to the water outlet channel 11, and then outward through the water outlet channel 11. After pressing button 31, the limiting member 32 can engage with the stop groove 131, keeping the water outlet channel 11 open. Users do not need to maintain the pressing position of button 31 while pouring water, improving the user experience. Moreover, in this embodiment, by providing external teeth 12 and sliding grooves 13 on the lid body 1, the number of parts in the container lid 10 can be reduced, thereby lowering the manufacturing cost of the container lid 10 and improving the assembly efficiency of the container lid 10.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
