Description

Technical Field

[0001] This utility model relates to the field of containers, specifically to an antifoaming component, a cover assembly, and a liquid heating container. Background Technology

[0002] Existing health-preserving kettles have functions such as brewing tea and making nourishing soups, but they often produce foam during the heating process. When there is too much foam, it overflows from the lid, causing inconvenience to the user. Conventional health-preserving kettles usually try to prevent foam overflow by reducing the heating power. However, reducing the heating power will prolong the heating time, resulting in slower cooking speed and longer waiting time for the user, which affects the user experience. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a cover assembly and a liquid heating container to at least solve the problem of foam overflow when boiling tea or health soup in related technologies.

[0004] A first aspect of this utility model provides a defoaming component for a liquid heating container. The liquid heating container includes a cover, and the defoaming component includes a bubble-blocking plate and an extension, and has a foam channel disposed on the bubble-blocking plate or the extension. The lower part of the extension is connected to the bubble-blocking plate, and the upper part of the extension is used to connect to the cover. When the defoaming component is connected to the cover through the extension, the defoaming component and the cover cooperate to form a buffer cavity for breaking bubbles. The buffer cavity communicates with the foam channel and is at least partially located around the foam channel. The defoaming component provided in this embodiment includes a bubble baffle and an extension. The upper part of the extension is connected to the cover, so that the bubble baffle is located below the cover. When ingredients such as health soup or tea are fully tumbling in the liquid heating container, foam will be formed. As boiling continues, the foam accumulates and increases, rising inside the liquid heating container. Since the bubble baffle can prevent the foam from continuing to rise, the foam can only enter the buffer chamber through the foam channel with more space and less resistance. In the foam channel, some of the foam will be eliminated due to friction with the foam channel wall, forming a primary bubble breakage. After the foam channel is filled, the foam will enter the buffer chamber. The buffer chamber can ensure that the foam does not directly overflow the liquid heating container, giving the foam enough time to cool and break down. In addition, the buffer chamber is close to the cover and has a lower temperature than the inside of the container. The foam will quickly collapse and become smaller in the buffer chamber, achieving a secondary bubble breakage and preventing the foam from overflowing outside the liquid heating container. The defoaming component provided in this embodiment is connected to the bottom of the lid of the liquid heating container. It can eliminate the foam generated by boiling in the liquid heating container, prevent the foam from overflowing from the lid, and does not require reducing the heating power. It allows the food to tumble fully in the liquid heating container, achieving higher power heating, ensuring the food is fully heated, speeding up the cooking process, and saving the user's waiting time.

[0005] In some embodiments, the lower end of the extension is connected to the outer peripheral edge of the bubble baffle, or the bubble baffle is provided with a foam inlet, and the lower end of the extension is connected to the outer peripheral edge of the foam inlet. This arrangement, placing the extension at the outer peripheral edge of the bubble baffle or the foam inlet, helps to make the overall structure of the defoaming component neat and facilitates processing and production.

[0006] In some embodiments, the extension is formed as a hollow cylinder, a foam inlet is provided on the bubble baffle, the lower end of the hollow cylinder is connected to the outer peripheral edge of the foam inlet to form a foam channel, a buffer cavity is formed on the outer periphery of the hollow cylinder, and a foam outlet communicating with the buffer cavity is provided on the cylinder wall of the hollow cylinder.

[0007] In these embodiments, the foam in the liquid heating container enters the hollow cylinder through the foam inlet. In the hollow cylinder, some of the foam is eliminated due to friction with the hollow cylinder wall, forming a primary bubble break. After the hollow cylinder is filled, the foam enters the buffer chamber through the foam outlet with a larger aperture. The temperature in the buffer chamber is relatively lower than that in the container. At this time, most of the foam enters a low-temperature zone, and the foam collapses rapidly, becoming smaller, forming a secondary bubble break, further preventing the foam from overflowing outside the liquid heating container.

[0008] In some embodiments, the bubble baffle and the lower end of the hollow cylinder are integrally connected. This integral connection provides good mechanical properties, increasing the connection strength between the hollow cylinder and the bubble baffle, preventing them from separating and avoiding the bubble baffle falling from the hollow cylinder into the liquid heating container during use. Furthermore, the bubble baffle can be removed together with the hollow cylinder and the cover assembly for cleaning, and the connection between the hollow cylinder and the bubble baffle will not detach during cleaning, facilitating the cleaning process.

[0009] In some embodiments, the bubble baffle further includes a connecting ring extending downward from the edge of the foam inlet, with the lower end of the hollow cylinder inserted into the connecting ring and fixedly connected to it. This arrangement, with the connecting ring sleeved on the outside of the hollow cylinder, increases the contact area between the bubble baffle and the hollow cylinder due to the ring's height, thus improving the stability of the connection between them.

[0010] In some embodiments, the bubble baffle is flat and has reflux holes. The flat bubble baffle has a simple structure and is easy to manufacture. The reflux holes allow the liquid formed after the foam above the bubble baffle bursts to flow through to the bottom of the bubble baffle, realizing liquid reflux. This can prevent excessive liquid accumulation on the bubble baffle and also avoid waste.

[0011] In some embodiments, the bubble baffle gradually slopes downwards from its center outwards. This design creates a shape that is higher in the middle and lower around the edges, which facilitates the smooth flow of liquid formed after the foam bursts back from the bubble baffle into the liquid heating container.

[0012] In some embodiments, the extension is formed as a hollow cylinder, the lower end of which is connected to the outer peripheral edge of the bubble baffle. The bubble baffle is provided with a foam inlet, and the defoaming component also includes an inner ring sleeve, which is connected to the outer peripheral edge of the foam inlet to form a foam channel.

[0013] In these embodiments, the connection between the outer periphery of the baffle plate and the entire hollow cylinder makes the connection more stable. Furthermore, the entire hollow cylinder simplifies the processing of the extension, facilitating production. Foam in the liquid heating container enters the inner ring cylinder through the foam inlet. Within the inner ring cylinder, some of the foam is broken due to friction with the cylinder wall, forming a primary bubble break. After filling the inner ring cylinder, the foam crosses its upper edge and enters the buffer chamber, where a secondary bubble break occurs at a relatively lower temperature compared to the rest of the container, further preventing foam from overflowing outside the liquid heating container.

[0014] In some embodiments, the area of ​​the foam inlet is greater than or equal to 20 mm². 2 Within this range, the area of ​​the foam inlet is large enough so that the resistance of the foam in the container entering the foam channel through the foam inlet is smaller, which is more conducive to the foam in the container entering the buffer chamber.

[0015] In some embodiments, a plurality of spring tabs are provided on the outer wall of the hollow cylinder, spaced apart along the circumferential direction, for engaging with the inner wall of the opening of the liquid heating container. This arrangement allows the spring tabs to be supported between the inner wall of the container and the hollow cylinder, thereby limiting the rotation of the defoaming component.

[0016] In some embodiments, the bubble baffle includes a plate body and a rolled edge formed by bending from the outer peripheral edge of the plate body toward the lower surface of the plate body.

[0017] In these embodiments, the rolled edge on the outer periphery of the plate enhances its structural strength, prevents deformation, and prevents sharp structures such as burrs or sharp corners from forming on the thinner edges, thus avoiding hand injuries and improving the user experience. Furthermore, the rolled edge is formed by bending the outer periphery of the plate towards its lower surface, simplifying the manufacturing process. Additionally, the rolled edge's location on the lower part of the plate ensures that the upper surface remains unobstructed, facilitating the smooth return of liquid formed after foam bursting from the baffle plate to the liquid heating container.

[0018] In some embodiments, the bubble baffle includes a plate body and ribs connected to the lower surface of the outer peripheral edge of the plate body.

[0019] In these embodiments, ribs are provided on the outer periphery of the plate to enhance its structural strength, prevent deformation, and shield sharp structures such as burrs and corners formed at the thinner edges of the plate, thereby preventing users from cutting their hands during operation and improving the user experience. Furthermore, the ribs are located at the bottom of the plate to ensure that the upper surface of the plate is unobstructed, which facilitates the smooth flow of liquid formed after foam bursting back from the baffle plate into the liquid heating container.

[0020] The second aspect of this utility model provides a cover assembly, including: a cover; and an antifoaming component as provided in any embodiment of the first aspect of this application, wherein the cover and the antifoaming component are detachably connected.

[0021] Since the lid assembly provided in the embodiments of this utility model includes the defoaming component provided in any of the embodiments of the first aspect, it has all the beneficial effects of the defoaming component provided in any of the embodiments of the first aspect, which will not be listed one by one here. In addition, the lid and the defoaming component are detachably connected, and the defoaming component can be selectively installed according to actual needs. For example, the defoaming component is not installed when boiling water normally, but is installed when brewing tea or health-preserving soup; in addition, the defoaming component can also be removed from the lid for cleaning.

[0022] In some embodiments, a downwardly protruding boss is provided on the bottom wall of the cover. One of the boss and the upper end of the hollow cylinder of the defoaming component is provided with a plurality of rotating fasteners, and the other is provided with a plurality of rotating buckles. The plurality of rotating buckles can correspond one-to-one with the plurality of rotating fasteners, and the rotating fasteners can be rotated and fastened to the rotating buckles.

[0023] In these embodiments, the hollow cylinder is rotatably connected to the boss on the bottom wall of the cover. The hollow cylinder can be assembled with the cover simply by rotating it in the forward direction, and the hollow cylinder can be separated from the cover by rotating it in the reverse direction. This makes the installation and removal of the hollow cylinder simple and quick.

[0024] In some embodiments, a plurality of rotating buckles protrude from the inner sidewall of the hollow cylinder, and a plurality of rotating fasteners protrude from the outer sidewall of the boss, with a preset distance between two adjacent rotating fasteners; and / or the rotating fastener includes a first limiting rib extending in the lateral direction and a second limiting rib extending upward from the upper surface of the first limiting rib, the plurality of rotating buckles being able to be inserted one-to-one into the preset distance between two adjacent rotating fasteners, and rotating in the circumferential direction to above the first limiting rib, the second limiting rib being able to stop the rotating buckle.

[0025] In these embodiments, when installing the hollow cylinder, simply align the rotating buckle vertically with the spacing between two adjacent rotating buckle positions, insert the rotating buckle into the spacing between the two adjacent rotating buckle positions, and then rotate the hollow cylinder forward until the rotating buckle moves above the first limiting rib. This operation is convenient. When disassembling the hollow cylinder, simply rotate the hollow cylinder in the opposite direction to separate the rotating buckle from the first limiting rib, and then pull the hollow cylinder downwards. Furthermore, the second limiting rib can stop the rotating buckle, preventing the hollow cylinder from rotating excessively.

[0026] The third aspect of this utility model provides a liquid heating container, comprising: a container body having a container opening; and a cover assembly as provided in any embodiment of the second aspect of this application, the cover assembly covering the container opening; and when the cover assembly is covering the container opening, a gap is left between the cover assembly and the container body, and a buffer cavity communicates with the outside through the gap.

[0027] Since the liquid heating container provided in the embodiments of this utility model includes the cover assembly provided in any embodiment of the second aspect, it has all the beneficial effects of the cover assembly provided in any embodiment of the second aspect, which will not be listed one by one here. In addition, when the cover assembly is closed onto the container body, a gap is left between it and the container body, so that the buffer cavity can be connected to the outside of the liquid heating container through the gap, making the temperature in the buffer cavity lower than that in the container body. This can effectively break bubbles through the temperature difference. When foam enters the buffer cavity, most of the foam collapses rapidly and becomes smaller because it enters a low-temperature zone, preventing foam from overflowing outside the liquid heating container.

[0028] In some embodiments, a reflux gap is formed between the outer peripheral edge of the bubble baffle and the inner sidewall of the container. This configuration allows the liquid formed after the foam above the bubble baffle bursts to flow through the reflux gap to the area below the bubble baffle, achieving liquid reflux and preventing excessive liquid accumulation on the bubble baffle, while also avoiding waste.

[0029] In some embodiments, the gap between the outer peripheral edge of the bubble baffle and the inner sidewall of the container body is greater than or equal to 0.5 mm and less than or equal to 5 mm. Within this range, on the one hand, the gap is small enough that foam cannot overflow above the bubble baffle through the gap, and on the other hand, the gap is large enough that the liquid formed after the foam bursts and the condensate on the bubble baffle can flow smoothly back into the container body.

[0041] The following will combine Figures 1 to 8 This invention introduces the defoaming component 20, the cover assembly, and the liquid heating container provided in the embodiments of this utility model.

[0042] like Figure 1 , Figure 2 , Figures 4 to 8 As shown, a first aspect of this utility model provides a defoaming component 20 for a liquid heating container. The liquid heating container includes a cover 10. The defoaming component 20 includes a bubble-blocking plate 210 and an extension, and has a foam channel disposed on the bubble-blocking plate 210 or the extension. The lower part of the extension is connected to the bubble-blocking plate 210, and the upper part of the extension is used to connect to the cover 10. When the defoaming component 20 is connected to the cover 10 through the extension, the defoaming component 20 and the cover 10 cooperate to form a buffer cavity 150 for defoaming. The buffer cavity 150 communicates with the foam channel and is at least partially located around the foam channel.

[0043] The defoaming component 20 provided in this embodiment includes a bubble baffle 210 and an extension. The upper part of the extension is connected to the cover 10, so that the bubble baffle 210 is located below the cover 10. When ingredients such as health soup or tea are fully tumbling in the liquid heating container 30, foam will be formed. As boiling continues, the foam accumulates and increases, rising inside the liquid heating container. Since the bubble baffle 210 can prevent the foam from continuing to rise, the foam can only enter the buffer chamber 150 through the foam channel with more space and less resistance. In the foam channel, some of the foam will be eliminated due to friction with the foam channel wall, forming a primary bubble breakage. After the foam channel is filled, the foam will enter the buffer chamber 150. The buffer chamber 150 can ensure that the foam does not directly overflow the liquid heating container, giving the foam enough time to cool and break bubbles. In addition, the buffer chamber 150 is close to the cover 10 and has a lower temperature than the container 30. The foam will quickly collapse and become smaller in the buffer chamber 150, achieving a secondary bubble breakage and preventing the foam from overflowing outside the liquid heating container. The defoaming component 20 provided in this embodiment is connected below the lid assembly of the liquid heating container. It can eliminate the foam generated by boiling in the liquid heating container, prevent the foam from overflowing from the lid 10, and does not require reducing the heating power. It allows the food to tumble fully in the liquid heating container, achieving higher power heating, allowing the food to be fully heated, speeding up the cooking process, and saving the user's waiting time.

[0044] It is worth noting that, such as Figure 1 , Figure 2 , Figures 4 to 8 As shown, liquid heating containers generally have a drain spout 320, which connects the inside and outside of the liquid heating container. This allows the buffer chamber 150 to be connected to the outside of the liquid heating container through the drain spout 320, further lowering the temperature in the buffer chamber 150. This effectively breaks bubbles through the temperature difference. When foam enters the buffer chamber 150, most of the foam collapses rapidly and becomes smaller due to entering a low-temperature zone, preventing the foam from overflowing outside the liquid heating container.

[0045] Of course, in other embodiments, a steam hole that can connect the inside and outside of the liquid heating container can also be provided on the cover assembly, so that the buffer chamber 150 can be connected to the outside of the liquid heating container through the steam hole, thereby making the temperature in the buffer chamber 150 relatively lower and improving the bubble breaking effect.

[0046] Furthermore, in some embodiments, the extension may be a plurality of sheet-like or strip-like structures connected between the cover 10 and the bubble baffle 210; or, the extension may be a cylindrical structure connected between the cover assembly and the bubble baffle 210.

[0047] In some embodiments, the lower end of the extension is connected to the outer peripheral edge of the bubble baffle 210, or the bubble baffle 210 is provided with a foam inlet 214, and the lower end of the extension is connected to the outer peripheral edge of the foam inlet 214. This arrangement, placing the extension at the outer peripheral edge of the bubble baffle 210 or the outer peripheral edge of the foam inlet 214, helps to make the overall structure of the defoamer 20 neat and facilitates processing and production.

[0048] Of course, the lower end of the extension can also be connected to any part of the bubble baffle 210 between the outer peripheral edge of the bubble baffle 210 and the outer peripheral edge of the foam inlet 214, which can also serve as a connection.

[0049] In the first embodiment of this application, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the extension is formed as a hollow cylinder 230, a foam inlet 214 is provided on the bubble baffle 210, the lower end of the hollow cylinder 230 is connected to the foam inlet 214 to form a foam channel, a buffer cavity 150 is formed on the outer periphery of the hollow cylinder 230, and a foam outlet 232 connected to the buffer cavity 150 is provided on the cylinder wall of the hollow cylinder 230.

[0050] In these embodiments, the foam in the liquid heating container enters the hollow cylinder 230 through the foam inlet 214. In the hollow cylinder 230, some of the foam is eliminated due to friction with the wall of the hollow cylinder 230, forming a primary bubble break. After the hollow cylinder 230 is filled, the foam enters the buffer chamber 150 through the foam outlet 232 with a larger aperture. The temperature in the buffer chamber 150 is relatively lower than that in the container body 30. At this time, most of the foam enters a low temperature zone, and the foam collapses rapidly, becoming smaller, forming a secondary bubble break, further preventing the foam from overflowing outside the liquid heating container.

[0051] In some embodiments, the area of ​​the foam inlet 214 is greater than or equal to 20 mm². 2 Within this range, the area of ​​the foam inlet 214 is large enough so that the resistance of the foam in the container 30 entering the foam channel through the foam inlet 214 is smaller, which is more conducive to the foam in the container 30 entering the buffer chamber 150.

[0052] In some embodiments, the aperture of the foam outlet 232 is greater than or equal to 15 mm. Within this range, it can be ensured that the aperture of the foam outlet 232 is large enough to minimize resistance to the foam and allow it to pass through smoothly.

[0053] In some embodiments, the bubble baffle 210 and the lower end of the hollow cylinder 230 are integrally connected. This integral connection provides good mechanical properties, increasing the connection strength between the hollow cylinder 230 and the bubble baffle 210, preventing them from separating and avoiding the bubble baffle 210 falling from the hollow cylinder 230 into the liquid heating container during use. Furthermore, the bubble baffle 210 can be removed together with the hollow cylinder 230 and the cover assembly for cleaning, and the connection between the hollow cylinder 230 and the bubble baffle 210 will not detach during cleaning, facilitating the cleaning process.

[0054] Furthermore, in some embodiments, the hollow cylinder 230 and the bubble baffle 210 are integrally formed, or the hollow cylinder 230 and the bubble baffle 210 are welded or riveted together. Integral forming, welding, and riveting can all achieve an integral connection between the hollow cylinder 230 and the bubble baffle 210, which has the advantages of a stable connection and the connection not being easy to loosen.

[0055] In other embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the bubble baffle 210 also includes a connecting ring extending downward from the edge of the foam inlet 214. The lower end of the hollow cylinder 230 is inserted into the connecting ring and fixedly connected to it. With this arrangement, the connecting ring is fitted onto the outside of the hollow cylinder 230, increasing the contact area between the bubble baffle 210 and the hollow cylinder 230 due to the ring's height, thus improving the stability of the connection between them.

[0056] Specifically, as an example, optionally, the bottom end of the connecting ring overlaps with the bottom end of the hollow cylinder 230 and is rolled up to form a flange to connect the bubble baffle 210 and the hollow cylinder 230. No additional screws, clips or other connecting parts are required, and the connection is stable and not easy to loosen.

[0057] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the bubble baffle 210 is flat and has return holes 213. The flat bubble baffle 210 has a simple structure and is easy to manufacture. Furthermore, multiple return holes 213 are provided on the flat bubble baffle 210. The return holes 213 allow the liquid formed after the foam above the bubble baffle 210 bursts to flow to the bottom of the bubble baffle 210 through the return holes 213, realizing liquid return. This can prevent excessive liquid accumulation on the bubble baffle 210 and also avoid waste.

[0058] In other embodiments, the bubble baffle 210 gradually slopes downward from its center outwards. This arrangement creates a shape that is higher in the middle and lower around the edges, which facilitates the smooth flow of liquid formed after the foam bursts back from the bubble baffle 210 into the liquid heating container.

[0059] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the bubble baffle 210 includes a plate body 211 and a rolled edge 212 formed by bending from the outer peripheral edge of the plate body 211 toward the lower surface of the plate body 211.

[0060] In these embodiments, a rolled edge 212 is provided on the outer peripheral edge of the plate 211, which can improve the structural strength of the plate 211, prevent deformation, and also prevent the thinner plate 211 from having sharp structures such as burrs / sharp corners, thereby avoiding user hand injuries during operation and improving the user experience. Furthermore, the rolled edge 212 is formed by bending the outer peripheral edge of the plate 211 toward the lower surface of the plate 211, which simplifies the manufacturing process. In addition, the rolled edge 212 is located below the plate 211, which ensures that the upper surface of the plate 211 is not obstructed, which is conducive to the smooth flow of liquid formed after the foam bursts back from the bubble baffle 210 to the liquid heating container.

[0061] In some embodiments, the bubble baffle 210 includes a plate body 211 and ribs connected to the lower surface of the outer peripheral edge of the plate body 211.

[0062] In these embodiments, ribs are provided on the outer peripheral edge of the plate 211, which can improve the structural strength of the plate 211, prevent deformation, and also shield the sharp structures such as burrs / sharp corners formed at the edge of the thinner plate 211, thereby preventing users from scratching their hands during operation and improving the user experience. Furthermore, the ribs are located below the plate 211, which ensures that the upper surface of the plate 211 is not obstructed, which facilitates the smooth flow of liquid formed after the foam bursts back from the bubble baffle 210 into the liquid heating container.

[0063] like Figure 1 , Figure 2 , Figure 4 , Figures 5 to 8 As shown, the second aspect of this utility model provides a cover assembly, including: a cover 10; and an antifoaming component 20 as provided in any embodiment of the first aspect of this application, wherein the cover 10 and the antifoaming component 20 are detachably connected.

[0064] Since the lid assembly provided in the embodiments of this utility model includes the defoaming component 20 provided in any embodiment of the first aspect, it has all the beneficial effects of the defoaming component 20 provided in any embodiment of the first aspect, which will not be listed one by one here. In addition, the lid 10 and the defoaming component 20 are detachably connected, and the defoaming component 20 can be selectively installed according to actual needs. For example, the defoaming component 20 can be left uninstalled when boiling water, but installed when brewing tea or health-preserving soup. In addition, the defoaming component 20 can be removed from the lid 10 for cleaning.

[0065] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a downward protruding boss 113 is provided on the bottom wall of the cover 10. One of the boss 113 and the upper end of the hollow cylinder 230 is provided with multiple rotating fasteners 114, and the other is provided with multiple rotating buckles 233. The multiple rotating buckles 233 can correspond one-to-one with the multiple rotating fasteners 114, and the rotating fasteners 114 can be rotated and fastened to the rotating buckles 233.

[0066] In these embodiments, the hollow cylinder 230 is rotatably fastened to the boss 113 on the bottom wall of the cover 10. The hollow cylinder 230 can be assembled with the cover 10 by simply rotating it in the forward direction, and the hollow cylinder 230 can be separated from the cover 10 by rotating it in the reverse direction. This makes the installation and removal of the hollow cylinder 230 simple and quick.

[0067] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, multiple rotating buckles 233 protrude from the inner wall of the hollow cylinder 230, and multiple rotating fasteners 114 protrude from the outer wall of the boss 113. There is a preset distance between two adjacent rotating fasteners 114. Each rotating fastener 114 includes a first limiting rib 1141 extending in the lateral direction and a second limiting rib 1142 extending upward from the upper surface of the first limiting rib 1141. The multiple rotating buckles 233 can be inserted into the preset distance between two adjacent rotating fasteners 114 one by one, and rotate in the circumferential direction to the top of the first limiting rib 1141. The second limiting rib 1142 can stop the rotating buckles 233.

[0068] In these embodiments, when installing the hollow cylinder 230, simply align the rotating buckle 233 vertically with the distance between the two adjacent rotating buckle positions 114, insert the rotating buckle 233 into the distance between the two adjacent rotating buckle positions 114, and then rotate the hollow cylinder 230 forward (e.g., ...). Figure 1 and Figure 5 As shown in the specific embodiment of this application, forward rotation is clockwise rotation, which moves the rotating buckle 233 above the first limiting rib 1141, making operation convenient. When it is necessary to disassemble the hollow cylinder 230, simply rotate the hollow cylinder 230 in the reverse direction (e.g., Figure 1 and Figure 5 As shown, in a specific embodiment of this application, the reverse rotation is a counterclockwise rotation, which separates the rotating buckle 233 from the first limiting rib 1141, and then the hollow cylinder 230 can be pulled downwards. Furthermore, the second limiting rib 1142 can stop the rotating buckle 233 and prevent the hollow cylinder 230 from rotating excessively.

[0069] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the cover assembly also includes a handle 140; the cover 10 includes a first cover 110 and a second cover 120, the second cover 120 being disposed above and connected to the first cover 110, and the handle 140 being disposed on the upper surface of the second cover 120. The second cover 120 can be disposed above the first cover 110, with the handle 140 on the second cover 120, which serves as an outer cover.

[0070] Furthermore, regarding the connection structure between the second cover 120 and the first cover 110, as an example, optionally, the second cover 120 is provided with a downwardly protruding mounting post 121, the mounting post 121 is provided with a threaded hole, the first cover 110 is provided with a mounting hole, and the cover assembly also includes a fastener 130, the fastener 130 passes upward through the mounting hole and locks in the threaded hole, connecting the first cover 110 to the second cover 120.

[0071] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first cover 110 includes a cover plate and a first cover flange 111 extending downward from the outer peripheral edge of the cover plate. The bottom end of the first cover flange 111 is provided with a first cover outer flange 112. The cover assembly also includes a sealing ring 40, which is sleeved on the first cover flange 111. The first cover outer flange 112 abuts against the sealing ring 40 from below to prevent the sealing ring 40 from falling off and to ensure a sealing effect.

[0072] In other embodiments, the cover assembly also includes a handle 140; such as Figure 7 and Figure 8 As shown, the handle 140 is provided on the upper surface of the cover 10; that is, the cover 10 is used directly as an outer cover.

[0073] It is understandable that the handle 140 can be an integral structure molded with the lid 10, for example, the handle 140 and the lid 10 can be made of stainless steel as a single piece. Furthermore, to prevent scalding, a heat-resistant sleeve, such as a silicone sleeve or a rubber sleeve, can be fitted over the handle 140. The handle 140 can also be a separately manufactured plastic part, installed on the lid 10 using screws or other connectors.

[0074] In the second embodiment of this application, the difference between the second embodiment and the first embodiment lies in the structure of the extension, the connection position between the lower end of the extension and the bubble baffle 210, and the positions of the rotating buckle 233 and the rotating buckle 114.

[0075] Specifically, in the second embodiment of this application, as Figure 7 and Figure 8 As shown, the lower end of the extension is connected to the outer peripheral edge of the bubble baffle 210. As an example, the extension may optionally include a hollow cylinder 230, which is formed as a complete outer ring. The bubble baffle 210 and the cover 10 are connected by the complete outer ring, making the connection more stable. In addition, the complete outer ring also simplifies the processing technology of the extension and is beneficial to manufacturing.

[0076] Furthermore, such as Figure 7 and Figure 8 As shown, the cover 10 includes a cover body connected to the cover body and a ring edge 101 extending downward from the lower surface of the cover body. One of the extension and the ring edge 101 is provided with a plurality of rotating fasteners 114, and the other is provided with a plurality of rotating latches 233. The plurality of rotating latches 233 can be rotated and fastened to the plurality of rotating fasteners 114 in a one-to-one correspondence.

[0077] In these embodiments, the hollow cylinder 230 is rotatably fastened to the flange 101 of the cover 10. The assembly of the hollow cylinder 230 with the cover 10 can be achieved by rotating the hollow cylinder 230 in the forward direction, and the hollow cylinder 230 can be separated from the cover 10 by rotating the hollow cylinder 230 in the reverse direction. This makes the operation of installing and removing the defoaming component 20 simple and quick.

[0078] Furthermore, multiple rotating buckles 233 protrude from the inner wall of the hollow cylinder 230, and multiple rotating buckle positions 114 protrude from the outer wall of the flange 101. There is a preset distance between two adjacent rotating buckle positions 114. Each rotating buckle position 114 includes a first limiting rib 1141 extending in the lateral direction and a second limiting rib 1142 extending upward from the upper surface of the first limiting rib 1141. The multiple rotating buckles 233 can be inserted into the preset distance between two adjacent rotating buckle positions 114 one by one, and rotate in the circumferential direction to the top of the first limiting rib 1141. The second limiting rib 1142 can stop the rotating buckles 233.

[0079] In these embodiments, when installing the defoaming component 20, simply align the rotating buckle 233 vertically with the gap between the two adjacent rotating buckle positions 114, insert the rotating buckle 233 into the gap between the two adjacent rotating buckle positions 114, and then rotate the defoaming component 20 forward (e.g., ...). Figure 7 As shown in the specific embodiment of this application, forward rotation is clockwise rotation, which moves the rotating buckle 233 above the first limiting rib 1141, making operation convenient. When it is necessary to disassemble the defoaming component 20, simply rotate the defoaming component 20 in the reverse direction (e.g., Figure 7 As shown, in a specific embodiment of this application, the reverse rotation is a counterclockwise rotation, which separates the rotating buckle 233 from the first limiting rib 1141, and then the defoaming component 20 can be pulled downwards. Furthermore, the second limiting rib 1142 can stop the rotating buckle 233 and prevent the defoaming component 20 from rotating excessively.

[0080] Furthermore, an inwardly recessed portion 102 is provided on the outer wall of the retaining edge 101, and the rotating fastener 114 is disposed in the recessed portion 102. Since both the rotating fastener 114 and the rotating latch 233 need to be protruding, when the cover 10 is closed onto the container body 30, there will be a gap between the inner wall of the container body 30 and the retaining edge 101 of the cover 10. By placing the rotating fastener 114 in the recessed portion 102, this gap can be minimized as much as possible, so that the retaining edge 101 fits more closely to the inner wall of the container body 30.

[0081] Furthermore, such as Figure 7 and Figure 8As shown, a foam inlet 214 is provided on the bubble baffle 210. An inner ring cylinder 250 is also provided on the outer periphery of the foam inlet 214 on the bubble baffle 210. The inner ring cylinder 250 forms a foam channel. The foam in the liquid heating container can pass over the upper edge of the inner ring cylinder 250 and enter the buffer chamber 150. Correspondingly, some of the foam in the inner ring cylinder 250 will be eliminated due to friction with the cylinder wall of the inner ring cylinder 250, forming a primary bubble break. After the foam fills the inner ring cylinder 250, it will pass over the upper edge of the inner ring cylinder 250 and enter the buffer chamber 150. A secondary bubble break is formed in the buffer chamber 150, which has a relatively lower temperature than the container body 30, further preventing the foam from overflowing outside the liquid heating container.

[0082] Furthermore, such as Figure 7 and Figure 8 As shown, a plurality of spring pieces 241 are provided on the outer side wall of the hollow cylinder 230, which are spaced apart along the circumferential direction. The spring pieces 241 can be supported between the inner wall of the container body 30 and the hollow cylinder 230 to limit the rotation of the defoaming component 20.

[0083] Furthermore, a water outlet is provided on the hollow cylinder 230, and the position of the water outlet corresponds to the position of the water spout of the container body 30. This allows the liquid inside the container body 30 to enter above the bubble-deflecting plate 210 through the return hole 213, flow through the water outlet to the water spout, and then flow out through the water spout, thus allowing water to be poured out without removing the defoamer 20. The placement of the water outlet, corresponding to the position of the water spout of the container body 30, ensures a reasonable flow path for the liquid inside the container body 30 during pouring, facilitating water discharge.

[0084] like Figure 1 , Figure 2 , Figures 4 to 8 As shown, the third aspect of this utility model provides a liquid heating container, including: a container body 30, on which a container opening 310 is provided; and a cover assembly as provided in any embodiment of the second aspect of this application, the cover assembly covering the container opening 310; and when the cover assembly is covering the container opening 310, a gap is left between the cover assembly and the container body 30, and the buffer cavity 150 communicates with the outside through the gap.

[0085] Since the liquid heating container provided in the embodiments of this utility model includes the cover assembly provided in any embodiment of the second aspect, it has all the beneficial effects of the cover assembly provided in any embodiment of the second aspect, which will not be listed one by one here. In addition, when the cover assembly is closed onto the container body 30, a gap is left between it and the container body 30, so that the buffer cavity 150 can be connected to the outside of the liquid heating container through the gap, so that the temperature in the buffer cavity 150 is lower than that inside the container body 30. This can effectively break bubbles through temperature difference. When foam enters the buffer cavity 150, most of the foam collapses rapidly and becomes smaller because it enters a low temperature zone, preventing foam from overflowing outside the liquid heating container.

[0086] In some embodiments, a reflux gap is formed between the outer peripheral edge of the bubble baffle 210 and the inner sidewall of the container body 30. This configuration allows the liquid formed after the foam above the bubble baffle 210 bursts to flow through the reflux gap to the area below the bubble baffle 210, achieving liquid reflux. This avoids excessive liquid accumulation on the bubble baffle 210 and also prevents waste.

[0087] Furthermore, in some embodiments, the bubble baffle 210 is provided with circular reflux holes and / or rectangular reflux holes.

[0088] In these embodiments, the circular and rectangular reflux holes facilitate the smooth return of the liquid formed after the foam on the bubble baffle 210 bursts and the condensed liquid on the bubble baffle 210 to the container body 30. They are also regular in shape, which is convenient for processing and production. Furthermore, the circular reflux holes have the advantages of smooth inner walls and easy cleaning.

[0089] Furthermore, the diameter of the circular reflux hole is greater than or equal to 0.5 mm and less than or equal to 5 mm. Within this range, on the one hand, the diameter of the reflux hole 213 is small enough that the foam cannot pass smoothly through the bubble baffle 210, ensuring that the foam in the container body 30 does not overflow upward from the reflux hole 213. On the other hand, the diameter of the reflux hole 213 is large enough that the liquid formed after the foam bursts and the condensed liquid on the bubble baffle 210 can flow smoothly back into the container body 30.

[0090] Furthermore, the width of the rectangular reflux orifice is greater than or equal to 0.5 mm, and the area is less than 30 mm². 2 Within this range, it can be ensured that the width of the return orifice 213 is sufficient to allow the liquid formed after foam bursting and the condensate on the baffle plate 210 to flow smoothly back into the container body 30. The area of ​​the rectangular return orifice is set to be less than 30 mm². 2 This ensures that the area of ​​the reflux hole 213 is small enough that the foam cannot pass smoothly through the bubble baffle 210, thus preventing the foam in the container body 30 from overflowing upwards from the reflux hole 213.

[0091] It is worth noting that when ingredients such as health-preserving soup or tea are fully swirled within container 30, foam will form. As boiling continues, the foam accumulates and increases. Therefore, the size of the reflux hole 213 needs to be limited to prevent the foam from passing smoothly through the baffle plate 210. The foam will accumulate on the baffle plate 210, blocking the reflux hole 213 and forming a barrier. This separates the buffer chamber 150 from the space below container 30. Since the buffer chamber 150 is located close to the lid 10, it can still communicate with the outside through the spout 320 or steam hole, where the temperature is relatively lower. This effectively breaks the foam through temperature difference. Furthermore, because the reflux hole 213 has a small aperture, the foam cannot pass through easily. Instead, the foam can only enter the foam channel through the larger, less resistant foam inlet 214, and then enter the buffer chamber 150.

[0092] In some embodiments, such as Figure 4 and Figure 6 As shown, the gap A between the outer peripheral edge of the bubble baffle 210 and the inner wall of the container body 30 is greater than or equal to 0.5 mm and less than or equal to 5 mm. Within this range, on the one hand, the gap is small enough that foam cannot overflow above the bubble baffle 210 through the gap, and on the other hand, the gap is large enough that the liquid formed after the foam bursts and the condensate on the bubble baffle 210 can flow smoothly back into the container body 30.

[0093] In some embodiments, the liquid heating container can be an electric kettle, a health pot, a tea maker, etc.

[0094] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
