Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to the field of household appliances, and more particularly to a lid assembly and a liquid heating container. [Background technology]

[0002] Lids for conventional liquid heating containers often have a water supply passage connecting the inside and outside of the container body. To prevent spillage of the liquid inside when the container is tilted, a water seal valve is typically provided to close the water supply passage and is opened only when pouring water. Furthermore, when boiling water, a large amount of steam is generated inside the kettle, and to prevent excessive pressure buildup inside the kettle and potential danger, the steam must be released in a timely manner. Therefore, the water seal valve must be equipped with a pressure-relief mechanism to release the pressure. Conventional pressure-relief mechanisms typically include a pressure-relief hole in the water seal valve, which is closed by inserting a silicone plug into the hole. However, this configuration presents a problem: it is difficult to stably control the fitting force between the silicone plug and the pressure-relief hole. If the fit is too loose, the pressure-reducing function is lost due to poor sealing, and if the fit is too tight, steam is difficult to release, resulting in low safety. Furthermore, once activated, the mechanism cannot be automatically reset, resulting in a poor user experience. Summary of the Invention [Problem to be solved by the invention]

[0003] An object of the present disclosure is to solve at least one of the technical problems existing in the above-mentioned conventional or related art. [Means for solving the problem]

[0004] To this end, a first aspect of the present disclosure provides a lid assembly.

[0005] A second aspect of the present invention provides a liquid heating vessel.

[0006] According to a first aspect of the present invention, there is provided a lid assembly for a liquid heating container, the lid assembly comprising: a lid body having a water supply passage; a water seal valve movably arranged within the water supply passage, the water seal valve being able to open and close the water supply passage by movement of the water seal valve; a pressure reduction hole installed in the water seal valve; and a first seal ring fitted over the water seal valve, the outer wall of the first seal ring abutting against the inner wall of the water supply passage to block the water supply passage when water is trapped, the first seal ring having an elastic shielding sheet that covers the pressure reduction hole to block the pressure reduction hole, the first seal ring having an elastic shielding sheet that can be pushed open to reduce pressure when the pressure inside the liquid heating container is higher than a predetermined pressure.

[0007] The lid assembly according to this embodiment includes a lid body, a water seal valve, a pressure reduction hole, and a first seal ring. The water seal valve is movably mounted within the water supply passage of the lid body, and the first seal ring is fitted over the water seal valve. The water seal valve is movable between a position that opens the water supply passage and a position that closes it, thereby enabling the lid assembly to release and confine water. The first seal ring is movable with the water seal valve, and when water is confined, the outer wall of the first seal ring abuts against the inner wall of the water supply passage, closing the passage, thereby sealing it. Furthermore, the water seal valve has a pressure reduction hole, and the first seal ring includes an elastic shielding sheet that can cover the pressure reduction hole and close it. When the pressure inside the liquid heating container is higher than a predetermined pressure, the elastic shielding sheet is pushed open to reduce pressure, improving product safety. Covering the elastic shielding sheet over the pressure reduction hole seals the water supply passage. On the one hand, the elastic shielding sheet has a simple structure and is easy to process and manufacture, thereby reducing the manufacturing cost of the product. On the other hand, there is no need to provide a positioning structure between the elastic shielding sheet and the decompression hole, and the decompression hole can be blocked simply by covering the elastic shielding sheet with the sheet. As a result, when the pressure inside the liquid heating container gradually recovers to below the predetermined pressure, the elastic shielding sheet returns to its position blocking the decompression hole by its own elastic force and gravity, thereby achieving automatic recovery.

[0008] In the lid assembly according to this embodiment, the elastic shielding sheet of the first seal ring covers the pressure reduction hole of the water seal valve, forming a sealed structure between the lid assembly and the container body of the liquid heating container. When boiling water, if steam increases and the pressure inside the container body exceeds a predetermined pressure, the elastic shielding sheet overcomes gravity and pushes up, causing the steam inside the container body to be discharged through the pressure reduction hole, thereby achieving pressure reduction. Furthermore, as the steam is discharged, the pressure inside the container body gradually returns to below the predetermined pressure, and the elastic shielding sheet returns to its original position by its own elastic force and gravity, closing the pressure reduction hole, thereby achieving automatic recovery. The lid assembly according to this embodiment has the advantages of being capable of effective pressure reduction, being highly safe, automatically recovering after activation, being reusable, providing a comfortable user experience, and being low-cost to manufacture.

[0009] The lid assembly according to the above embodiment of the present disclosure may also have the following additional technical features.

[0010] In some embodiments, the water seal valve includes a water seal disk, the water seal disk is fitted with a first seal ring, and the pressure reduction hole is disposed on the water seal disk. The first seal ring includes a first seal seat, a second seal seat, and a connecting ring connected between the first and second seal seats. The first seal seat is positioned above the water seal disk, the elastic shielding sheet is connected to the first seal seat, and the second seal seat is positioned below the water seal disk, and the second seal seat is installed to avoid the pressure reduction hole. The first seal seat, the second seal seat, and the connecting ring surround and form a mounting groove, the opening of the mounting groove facing inward, and the water seal disk is attached to the mounting groove. With this configuration, the elastic shielding sheet is positioned above the water seal disk, and the second seal seat, positioned below the water seal disk, is positioned away from the pressure reduction hole. In other words, the second seal seat does not block the pressure reduction hole. With this structure, steam in the liquid heating container can push the elastic shielding sheet upward, opening the pressure reduction hole and achieving pressure reduction.

[0011] In some embodiments, the first sealing seat is annular, the resilient shielding seat is annular, the resilient shielding seat is fitted to the first sealing seat, and the outer peripheral wall of the resilient shielding seat is connected to the inner peripheral wall of the first sealing seat.

[0012] In these embodiments, the first seal sheet and the elastic shielding sheet are configured as annular sheets with large and small diameters, respectively, and the first seal sheet is positioned on the outer periphery, with the outer periphery of the elastic shielding sheet connected to the inner periphery of the first seal sheet. This stabilizes the connection between the first seal sheet and the elastic shielding sheet. Furthermore, since the annular elastic shielding sheet has a large area, if multiple decompression holes are provided, the multiple decompression holes are arranged annularly and installed at positions on the water seal disk corresponding to the annular elastic shielding sheet. Therefore, multiple decompression holes can be simultaneously blocked by a single annular elastic shielding sheet.

[0013] In some embodiments, the first seal seat is annular, and is connected to an elastic shielding sheet on an inner peripheral wall of the first seal seat at a position adjacent to the decompression hole, the elastic shielding sheet corresponding to the decompression hole.

[0014] In these embodiments, the elastic shielding sheet is connected to the inner peripheral wall of the first seal seat at a position adjacent to the decompression hole, so that the elastic shielding sheet can shield the nearby decompression hole. In such a configuration, the elastic shielding sheet can be formed as an independent small piece, which has the advantage of saving material and reducing costs.

[0015] In some embodiments, the number of decompression holes is plural, the number of elastic shielding sheets is plural, and the elastic shielding sheets are spaced apart from one another and correspond one-to-one to the plurality of decompression holes.

[0016] In some embodiments, the first seal ring further includes a connecting rib connecting the multiple elastic shielding sheets, the connecting rib being connected between two adjacent elastic shielding sheets or the connecting rib being connected to the end of the elastic shielding sheet that is away from the first seal sheet. This configuration allows one elastic shielding sheet to be placed above each decompression hole, ensuring that all decompression holes are reliably covered and sealed. Furthermore, the elastic shielding sheets are spaced apart, thereby saving material. Furthermore, the multiple elastic shielding sheets are connected to each other by the connecting rib, which increases the support force of the multiple elastic shielding sheets and provides a better watertight effect.

[0017] In some embodiments, the water sealing disk includes a disk body and a mounting portion disposed on the outer periphery of the disk body, the pressure reducing hole is disposed on the disk body, and the thickness of the mounting portion is smaller than the thickness of the disk body. The outer diameter of the mounting portion is preferably 1.05 to 1.2 times the diameter of the mounting groove.

[0018] In some embodiments, the water seal disc has a protrusion, and the first seal seat or the second seal seat has a recess that fits into the protrusion, and the protrusion is located within the recess.

[0019] In these embodiments, to facilitate attachment of the first seal ring, a thin annular attachment portion is provided on the outer periphery of the disk body, and / or a convex portion is provided on the water seal disk, and a concave portion that fits the convex portion is provided on the first seal seat or the second seal seat. The engagement between the convex portion and the concave portion more reliably secures the first seal ring to the water seal disk, making it less likely to fall off or become displaced. Furthermore, the outer diameter of the attachment portion is preferably 1.05 to 1.2 times the diameter of the attachment groove. Setting the diameter within this range avoids, on the one hand, problems in which an excessively large outer diameter of the attachment portion causes the first seal ring to be tightly fastened to the water seal disk, resulting in reduced pressure reduction performance and making it difficult for steam to push up the elastic shielding sheet. On the other hand, it also avoids problems in which an excessively small outer diameter of the attachment portion prevents the first seal ring from being properly expanded when attached to the water seal disk, resulting in insufficient elasticity and reduced watertightness and airtightness.

[0020] In some embodiments, the number of pressure reduction holes is 1 to 5. By configuring in this manner, excess steam can be discharged from the pressure reduction holes in a timely manner, and dangers caused by excessive increases in pressure inside the liquid heating container can be avoided. Furthermore, by setting the number of pressure reduction holes in the range of 1 to 5, on the one hand, the provision of at least one pressure reduction hole ensures the exhaust function, and on the other hand, there is no risk of a decrease in watertightness due to too many pressure reduction holes.

[0021] In some embodiments, the decompression holes are circular, and the diameter of the decompression holes is 1.5 mm or more and 3 mm or less. Such a configuration provides the advantage that circular exhaust holes have a regular shape and are easy to process and manufacture. Furthermore, by setting the diameter of the decompression holes to 1.5 mm or more and 3 mm or less within this range, on the one hand, it is possible to avoid the problems of difficulty in processing and poor moldability due to a decompression hole diameter of less than 1.5 mm, and it is easy to process and manufacture the product. On the other hand, it is also possible to avoid the problem of the watertight performance of the elastic shielding sheet being reduced due to a decompression hole diameter exceeding 3 mm, and it is possible to further prevent water or other liquids in the liquid heating container from leaking out through the decompression holes, thereby improving the sealing performance of the product.

[0022] In some embodiments, the thickness of the elastic shielding sheet is equal to or less than the thickness of the first seal sheet. By configuring it in this way, the thickness of the elastic shielding sheet may be equal to or less than the thickness of the first seal sheet. The thinner the elastic shielding sheet, the easier it is to be pushed up. However, since the first seal sheet is intended to be securely fixed to the water seal disk, it is not desirable to make the thickness of the first seal sheet excessively thin. Therefore, by designing the thickness of the elastic shielding sheet to be smaller than the thickness of the first seal sheet, it is possible to ensure that the first seal sheet is fixed to the water seal disk with sufficient strength while also ensuring that the elastic shielding sheet is smoothly pushed up by steam.

[0023] In some embodiments, the thickness of the elastic shielding sheet is 0.8 mm or more and 2 mm or less. By setting the thickness within this range, the elastic effect of the elastic shielding sheet is good. On the one hand, it is possible to avoid the problem of insufficient strength and easy breakage caused by an elastic shielding sheet being too thin, and on the other hand, it is possible to avoid the problem of reduced elasticity and difficulty in being pushed up by steam caused by an elastic shielding sheet being too thick.

[0024] In some embodiments, the lid body has a button hole, and the lid assembly includes: a button movably attached to the button hole; a water seal valve connected to the center of the water seal disk and further including an ejector rod extending upward; a rotating ring fitted onto the top of the ejector rod, the button being positioned above the rotating ring; and pressing the button presses the rotating ring, moving the ejector rod downward and opening the water supply passage; an elastic member, the upper end of which abuts against the underside of the rotating ring and the lower end of which abuts against the lid body, the restoring force of which pushes the rotating ring upward and returns the water seal valve and the button; a guide cylinder installed within the lid body, the ejector rod being drilled within the guide cylinder; and a second seal ring fitted onto the ejector rod, the side wall of the ejector rod having an annular engagement groove, the second seal ring being positioned within the engagement groove, and the outer wall of the second seal ring abutting against the inner wall of the guide cylinder.

[0025] In these embodiments, the button, rotating ring, water seal valve, and elastic member cooperate to move the water seal valve downward to open the water supply passage and return upward to close the water supply passage. Specifically, by pressing the button, the button presses the rotating ring connected to the water seal valve, which then moves the ejector rod downward to open the water supply passage. At this time, the elastic member can be provided with a locking mechanism in a compressed state, which holds the button and water seal valve in place and facilitates the water injection operation. After water injection is completed, by pressing the button again, the locking mechanisms are separated from each other, and the elastic force of the elastic member pushes the rotating ring upward, resetting the water seal valve and button and closing the water supply passage. Furthermore, a guide cylinder compatible with the ejector rod is provided within the cover body, and the guide cylinder is positioned to surround the outer periphery of the ejector rod, guiding the movement of the water seal valve and preventing the water seal valve from moving horizontally and reducing its water-stopping performance. In addition, the outer wall of the second seal ring abuts against the inner wall of the guide cylinder, thereby providing a water-stopping effect and preventing water from leaking out above the lid body through the gap between the guide cylinder and the ejector rod, thereby maintaining the cleanliness of the inside of the lid body.

[0026] According to a second aspect of the present invention, there is provided a liquid heating container comprising a container body having a container opening at an upper portion of the container body, and a lid assembly according to any one of the above technical solutions, the lid assembly being fitted over the container opening.

[0027] The body heating container according to this embodiment includes a lid assembly of any of the above-mentioned technical solutions, and therefore has the beneficial effects of any of the above-mentioned technical solutions, but each of them will not be described here.

[0028] Other aspects and / or advantages of the present invention will be set forth in part in the description that follows, and in part will be obvious from the description, or may be learned by practice of the present general inventive concepts. [Brief explanation of the drawings]

[0039] Hereinafter, lid assemblies and liquid heating containers according to several embodiments of the present disclosure will be described with reference to FIGS.

[0040] 1, 2, and 3, an embodiment of a first aspect of the present invention provides a lid assembly for a liquid heating container. The lid assembly includes a lid body 10 having a water supply passage 110, a water seal valve 20 movably provided within the water supply passage 110, the water seal valve 20 being able to open and close the water supply passage 110 by movement of the water seal valve 20, a pressure reduction hole 210 provided in the water seal valve 20, and a first seal ring 30 fitted onto the water seal valve 20, the outer wall of the first seal ring 30 abutting against the inner wall of the water supply passage 110 to close the water supply passage 110, the first seal ring 30 including an elastic shielding sheet 340 that covers the pressure reduction hole 210 to close it, and the elastic shielding sheet 340 being pushed open to reduce the pressure when the pressure inside the liquid heating container is higher than a predetermined pressure.

[0041] The lid assembly according to this embodiment includes a lid body 10, a water seal valve 20, a pressure reduction hole 210, and a first seal ring 30. The water seal valve 20 is movably disposed within a water supply passage 110 of the lid body 10. The first seal ring 30 is fitted over the water seal valve 20 and is movable between a position that opens the water supply passage 110 and a position that closes the water supply passage 110, thereby enabling the lid assembly to release and confine water. The first seal ring 30 is movable together with the water seal valve 20, and in the water-confining state, the outer wall of the first seal ring 30 abuts against the inner wall of the water supply passage 110 to close the water supply passage 110, thereby sealing the water supply passage 110. Furthermore, the water seal valve 20 is provided with a pressure reduction hole, and the first seal ring 30 is provided with an elastic shielding sheet 340. The elastic shielding sheet 340 is fitted over the pressure reduction hole 210 to block the pressure reduction hole 210. When the pressure inside the liquid heating container is higher than a predetermined pressure, the elastic shielding sheet 340 is pushed open to reduce the pressure, thereby improving product safety. By fitting the elastic shielding sheet 340 over the pressure reduction hole 210, the water supply passage 110 can be sealed. On the other hand, the elastic shielding sheet 340 has a simple structure and is easy to process and manufacture, thereby reducing product manufacturing costs. On the other hand, there is no need to provide a positioning structure between the elastic shielding sheet 340 and the pressure reduction hole 210; simply fitting the elastic shielding sheet 340 over the pressure reduction hole 210 can block the pressure reduction hole 210. As a result, when the pressure inside the liquid heating container gradually recovers to below the predetermined pressure, the elastic shielding sheet 340 returns to its original position by its own elastic force and gravity, and returns to the position blocking the pressure reduction hole 210, thereby realizing automatic recovery.

[0042] In the lid assembly according to this embodiment, the elastic shielding sheet 340 of the first seal ring 30 covers the pressure reduction hole 210 of the water seal valve 20, thereby forming a sealed structure between the lid assembly and the container body of the liquid heating container. When boiling water, if steam increases and the pressure inside the container body exceeds a predetermined pressure, the elastic shielding sheet 340 overcomes gravity and pushes up, causing the steam inside the container body to be discharged through the pressure reduction hole 210, thereby achieving pressure reduction. Furthermore, as the steam is discharged, the pressure inside the container body gradually returns to below the predetermined pressure, and the elastic shielding sheet 340 returns to its original position by its own elasticity and gravity, closing the pressure reduction hole 210, thereby achieving automatic recovery. The lid assembly according to this embodiment has the advantages of being capable of effective pressure reduction, being highly safe, automatically recovering after activation, being reusable, providing a comfortable user experience, and being low-cost to manufacture.

[0043] 1, 2, 3, and 4, regarding the specific structures of the water seal valve 20 and the first seal ring 30, in some embodiments, the water seal valve 20 includes a water seal disk 220, the water seal disk 220 is fitted to the first seal ring 30, the decompression hole 210 is disposed on the water seal disk 220, and the first seal ring 30 includes a first seal seat 310, a second seal seat 320, and a connecting ring 330 connected between the first seal seat 310 and the second seal seat 320. The first seal seat 310, the second seal seat 320, and the connecting ring 330 surround and form a mounting groove, the opening of which faces inward, and the water seal disk 220 is mounted in the mounting groove. The first sealing sheet 310 is positioned above the water sealing disk 220, the elastic shielding sheet 340 is connected to the first sealing sheet 310, the second sealing sheet 320 is positioned below the water sealing disk 220, and the second sealing sheet 320 is installed to avoid the decompression hole 210. With this configuration, the elastic shielding sheet 340 is positioned above the water sealing disk 220, and the second sealing sheet 320, which is positioned below the water sealing disk 220, is installed away from the decompression hole 210. In other words, the second sealing sheet 320 does not block the decompression hole 210, and with this structure, steam within the liquid heating container can push the elastic shielding sheet 340 upward, opening the decompression hole 210 and achieving decompression.

[0044] In some embodiments, as shown in Figures 3 and 4, the first sealing seat 310 is annular, the elastic shielding sheet 340 is annular, the elastic shielding sheet 340 is fitted to the first sealing seat 310, and the outer peripheral wall of the elastic shielding sheet 340 is connected to the inner peripheral wall of the first sealing seat 310.

[0045] In these embodiments, the first seal seat 310 and the elastic shielding sheet 340 are configured as annular sheets with large and small diameters, respectively, and the first seal seat 310 is positioned on the outer periphery, with the outer periphery of the elastic shielding sheet 340 connected to the inner periphery of the first seal seat 310. This stabilizes the connection between the first seal seat 310 and the elastic shielding sheet 340. Furthermore, since the area of ​​the annular elastic shielding sheet 340 is large, when multiple decompression holes 210 are provided, the multiple decompression holes are arranged annularly and installed at positions on the water sealing disk 220 corresponding to the annular elastic shielding sheet 340. Therefore, it is possible to simultaneously block multiple decompression holes 210 with one annular elastic shielding sheet 340.

[0046] In another embodiment, the first sealing seat is annular, and is connected to an elastic shielding sheet 340 on the inner peripheral wall of the first sealing seat 310 at a position adjacent to the decompression hole 210 , and the elastic shielding sheet 340 corresponds to the decompression hole 210 .

[0047] In these embodiments, the elastic shielding sheet 340 is connected to the inner peripheral wall of the first seal seat 310 at a position adjacent to the decompression hole 210, so that the elastic shielding sheet 340 can shield the nearby decompression hole 210. In such a configuration, the elastic shielding sheet 340 can be formed as an independent small piece, which has the advantage of saving material and reducing costs.

[0048] When the elastic shielding sheet 340 is made up of small independent pieces, the shape of the elastic shielding sheet 340 may be a fan ring shape, a sector shape, a circle, a rectangle, a trapezoid, or the like.

[0049] Furthermore, in some embodiments, the outer peripheral wall of the elastic shielding sheet 340 may be formed in an arc shape that matches the inner peripheral wall of the annular first seal seat 310 .

[0050] Furthermore, in some embodiments, there are multiple decompression holes 210 and multiple elastic shielding sheets 340, and the multiple elastic shielding sheets 340 are spaced apart and correspond one-to-one to the multiple decompression holes 210. The first seal ring 30 further includes connecting ribs connecting the multiple elastic shielding sheets 340, where the connecting ribs are connected between two adjacent elastic shielding sheets 340 or the connecting ribs are connected to the ends of the elastic shielding sheets 340 that are farther away from the first seal seat 310. This configuration allows one elastic shielding sheet 340 to cover each decompression hole 210, ensuring complete sealing by reliably covering all of the decompression holes 210. Furthermore, the elastic shielding sheets 340 are spaced apart, thereby saving material. Furthermore, the multiple elastic shielding sheets 340 are connected to each other by the connecting ribs, which increases the support force of the multiple elastic shielding sheets 340 and provides a better watertight seal.

[0051] Regarding the specific structure of the water seal disc 220, in some embodiments, as shown in Figures 4 and 5, the water seal disc 220 includes a disc body 221 and a mounting portion 222 disposed on the outer periphery of the disc body 221, the decompression holes 210 are disposed in the disc body 221, and the thickness of the mounting portion 222 is smaller than the thickness of the disc body 221. The outer diameter of the mounting portion 222 is 1.05 to 1.2 times the diameter of the mounting groove. The water seal disc 220 has a protrusion 223, and the first seal seat 310 or the second seal seat 320 has a recess that fits into the protrusion 223, and the protrusion 223 is positioned within the recess.

[0052] In these embodiments, to facilitate attachment of the first seal ring 30, a thin mounting portion 222 is provided annularly on the outer periphery of the disk body 221, and further, a convex portion 223 is provided on the water seal disk 220, and a concave portion that fits the convex portion 223 is provided on the first seal seat 310 or the second seal seat 320. The engagement between the convex portion 223 and the concave portion ensures that the first seal ring 30 and the water seal disk 220 are fixed more reliably, making it less likely that they will fall off or become displaced. Furthermore, the outer diameter of the mounting portion 222 is 1.05 to 1.2 times the diameter of the attachment groove. By setting it within this range, on the one hand, it is possible to avoid the problem that if the outer diameter of the mounting portion 222 is too large, the first seal ring 30 is tightly fastened to the water seal disc 220, reducing pressure reduction performance and making it difficult for steam to push up the elastic shielding sheet 340, and on the other hand, it is also possible to avoid the problem that if the outer diameter of the mounting portion 222 is too small, the first seal ring 30 is not properly pushed out when attached to the water seal disc 220, resulting in insufficient elasticity and reduced watertightness and airtightness.

[0053] As an optional configuration, for example, the convex portion 223 is provided on the lower surface of the water sealing disc 220 and the concave portion is provided on the upper surface of the second sealing seat 320.

[0054] In some embodiments, the number of pressure reduction holes 210 is 1 to 5, as shown in Figure 5. With such a configuration, excess steam can be discharged from the pressure reduction holes in a timely manner, and dangers caused by excessive increases in pressure inside the liquid heating container can be avoided. Furthermore, by setting the number of pressure reduction holes 210 in the range of 1 to 5, on the one hand, the provision of at least one pressure reduction hole 210 ensures exhaust function, and on the other hand, there is no risk of a decrease in watertightness due to too many pressure reduction holes 210.

[0055] Preferably, there are multiple decompression holes 210. When the pressure inside the liquid heating container is too high, the multiple decompression holes 210 allow the internal steam to be uniformly and quickly discharged, thereby reducing the internal pressure.

[0056] In some embodiments, the decompression holes 210 are circular, and the diameter of the decompression holes 210 is 1.5 mm or more and 3 mm or less. Such a configuration provides the advantage that circular exhaust holes have a regular shape and are easy to process and manufacture. Furthermore, by setting the diameter of the decompression holes 210 to 1.5 mm or more and 3 mm or less within this range, on the one hand, it is possible to avoid the problems of difficulty in processing and poor moldability due to a decompression hole 210 with a diameter of less than 1.5 mm, and it is therefore easy to process and manufacture the product. On the other hand, it is also possible to avoid the problem of the watertight performance of the elastic shielding sheet 340 being reduced due to a diameter of the decompression holes 210 exceeding 3 mm, and it is possible to further prevent water or other liquids in the liquid heating container from leaking out through the decompression holes 210, thereby improving the sealing performance of the product.

[0057] In some embodiments, the thickness of the elastic shielding sheet 340 is equal to or less than the thickness of the first seal sheet 310. By configuring the elastic shielding sheet 340 in this manner, the thickness of the elastic shielding sheet 340 may be equal to or less than the thickness of the first seal sheet 310. The thinner the elastic shielding sheet 340, the easier it is to be pushed up. However, since the first seal sheet 310 is intended to be securely fixed to the water seal disk 220, it is not desirable to make the thickness of the first seal sheet 310 excessively thin. Therefore, by designing the thickness of the elastic shielding sheet 340 to be smaller than the thickness of the first seal sheet 310, it is possible to ensure that the first seal sheet 310 is fixed to the water seal disk 220 with sufficient strength, while also ensuring that the elastic shielding sheet 340 is smoothly pushed up by steam.

[0058] In some embodiments, the thickness of the elastic shielding sheet 340 is 0.8 mm or more and 2 mm or less. Setting the thickness within this range ensures a good elastic effect of the elastic shielding sheet 340. On the one hand, it is possible to avoid the problem of insufficient strength and susceptibility to breakage caused by an elastic shielding sheet 340 being too thin, and on the other hand, it is possible to avoid the problem of reduced elasticity and difficulty in being pushed up by steam caused by an elastic shielding sheet 340 being too thick.

[0059] In some embodiments, as shown in FIGS. 1, 2 and 3, the lid body 10 has a button hole, and the lid assembly includes a button 40 movably mounted in the button hole, a water seal valve 20 connected to the center of the water seal disk 220 and further including an ejector rod 230 extending upward, a rotating ring 50 fitted onto the upper part of the ejector rod 230, the button 40 being positioned above the rotating ring 50, and the rotating ring 50 being pressed by pressing the button 40, the ejector rod 230 being moved downward to open the water supply passage 110, and an elastic member 60, the upper end of which is connected to the rotating ring 50. the lower end of the elastic member 60 abuts against the underside of the lid body 10, and the lower end of the elastic member 60 abuts against the lid body 10, and the restoring force of the elastic member 60 pushes the rotating ring 50 upward, returning the water seal valve 20 and the button 40; a guide cylinder 70 installed in the lid body 10, and the ejector rod 230 is drilled into the guide cylinder 70; and a second seal ring 231 fitted onto the ejector rod 230, and a ring-shaped engagement groove 232 is provided on the side wall of the ejector rod 230, and the second seal ring 231 is positioned within the engagement groove 232, and the outer wall of the second seal ring 231 abuts against the inner wall of the guide cylinder 70.

[0060] In these embodiments, the button 40, rotating ring 50, water seal valve 20, and elastic member 60 work together to move the water seal valve 20 downward to open the water supply passage 110 and return upward to close the water supply passage 110. Specifically, by pressing the button 40, the button 40 pushes the rotating ring 50 connected to the water seal valve 20, causing the ejector rod 230 to move downward and open the water supply passage 110. At this time, the elastic member 60 can be provided with a locking structure in a compressed state, which holds the button 40 and water seal valve 20 in place and facilitates the water injection operation. After water injection is complete, pressing the button 40 again separates the locking structures, and the elastic force of the elastic member 60 pushes the rotating ring 50 upward, resetting the water seal valve 20 and button 40 and closing the water supply passage 110. Furthermore, a guide cylinder 70 that works in conjunction with the ejector rod 230 is provided inside the lid body 10, and the guide cylinder 70 is arranged to surround the outer periphery of the ejector rod 230, so that it can guide the movement of the water seal valve 20 and prevent a decrease in water stop performance due to horizontal movement of the water seal valve 20. In addition, the outer periphery wall of the second seal ring 231 abuts against the inner periphery wall of the guide cylinder 70, thereby achieving a water stop effect and preventing water from leaking out above the lid body 10 through the gap between the guide cylinder 70 and the ejector rod 230, thereby maintaining the cleanliness of the inside of the lid body 10.

[0061] The assembly process for each part of the lid assembly will be described below. The first seal ring 30 is fitted onto the mounting portion 222 of the water seal valve 20, and the second seal ring 231 is fitted onto the ejector rod 230 of the water seal valve 20 and engaged with the engagement groove 232. The lid body 10 comprises a lower lid and an upper lid. The assembled whole is then installed in the water supply passage 110 of the lower lid, the elastic member 60 is installed between the rotating ring 50 and the lower lid, and the rotating ring 50 is connected to the upper lid.

[0062] According to a second aspect of the present invention, there is provided a liquid heating container comprising a container body having a container opening at an upper portion of the container body, and a lid assembly according to any one of the above technical solutions, the lid assembly being fitted over the container opening.

[0063] The liquid heating container provided in this embodiment includes a lid assembly of any of the above-mentioned technical solutions, and therefore has the beneficial effects of any of the above-mentioned technical solutions, but each and every one of them will not be described here.

[0064] In the liquid heating container according to this embodiment, during normal boiling of water, the elastic shielding sheet 340 covers the pressure reduction hole 210 provided in the water seal valve 20, and the elastic, tight-fitting structure prevents steam leakage and provides a waterproof function. If excessive steam is present within the container body and the pressure reduction hole 210 is blocked and loses its function, the steam pressure acts on the pressure reduction hole 210, which pushes up and opens the elastic shielding sheet 340, allowing the steam to be discharged from the pressure reduction hole 210 and ultimately to the outside through the spout. If there is no pressure within the container body, or if the pressure has dropped sufficiently, the elastic shielding sheet 340 uses its own elastic force to cover the pressure reduction hole 210, completing a series of operations of exhaust and recovery.

[0065] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and changes to the embodiments of the present invention without departing from the spirit and scope of the present invention. In the opinion of those skilled in the art, these modifications and changes should be understood as still falling within the spirit and scope of the embodiments of the present invention as defined by the claims.
