Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water boiling equipment, and particularly relates to a liquid heating container and a liquid heating device. BACKGROUND

[0002] The container body of the existing liquid heating container is usually made of glass, and the bottom of the container body and the heating disc are sealed and connected together through silica gel. Due to the limitation of glass processing technology, the size tolerance of the container body is relatively large, which leads to the need for a large amount of silica gel to absorb the size tolerance between the container body and the heating disc, resulting in a large exposed area of silica gel and affecting the appearance aesthetics. SUMMARY

[0003] Therefore, the utility model aims to provide a liquid heating container and a liquid heating device, which can reduce the external leakage area of the sealing element between the container body and the heating disc and ensure the sealing effect.

[0004] An aspect of the utility model provides a liquid heating container, which comprises a container body, the upper and lower ends of the container body having openings, the lower end of the container body having an annular support platform extending radially inward, a heating disc arranged at the lower end opening of the container body, the edge of the lower surface of the heating disc being provided with a downwardly open mounting groove, the mounting groove being located above the annular support platform, a sealing element arranged in the mounting groove, a fixing plate arranged below the annular support platform, and a fastener connecting the fixing plate and the heating disc to clamp the heating disc and the fixing plate on both sides of the annular support platform and clamp the sealing element between the upper surface of the heating disc and the annular support platform.

[0005] The liquid heating container provided by the aspect of the utility model has the sealing element located on the inner side of the container body and clamped between the upper surface of the heating disc and the annular support platform, and the sealing element is also hidden in the downwardly open mounting groove of the heating disc, so that the sealing element is not exposed, the appearance aesthetics of the liquid heating container is improved, and the user experience is improved. Moreover, the fixing plate and the heating disc are clamped on both sides of the annular support platform through the fastener, the sealing element can be extruded, the sealing element is tightly attached to the heating disc and the annular support platform, the connection sealing property of the container body and the heating disc is ensured, and the installation stability of the heating disc is ensured.

[0006] In addition, the sealing element is arranged in the mounting groove, which can quickly install the sealing element in place in alignment with the position of the mounting groove, improve the assembly efficiency, limit the sealing element through the mounting groove, avoid the transverse movement of the sealing element during compression, ensure that the sealing element can be accurately and extensively extruded onto the annular support platform, and the mounting groove can also contact the sealing element on multiple surfaces, thereby improving the sealing effect of the sealing element.

[0007] Further, in some embodiments, the edge of the heat disc is raised upward to form an open downward mounting groove. With such design, it is convenient to provide mounting space for the sealing element without making the wall of the heat disc too thick, which can reduce material and save cost.

[0008] Further, in some embodiments, the distance between the groove side wall of the mounting groove and the upper surface of the annular support platform in the vertical direction is between 0.5mm and 2mm.

[0009] In these embodiments, after the fastener fastens the fixed plate and the heat disc together, the distance L2 between the groove side wall of the mounting groove and the upper surface of the annular support platform in the vertical direction is between 0.5mm and 2mm, which can avoid the groove side wall of the mounting groove directly pressing down on the annular support platform, causing the annular support platform to be rubbed or damaged, and at the same time, can ensure that the sealing element is fully compressed, thereby ensuring the sealing effect.

[0010] Further, in some embodiments, the upper surface of the sealing element has at least two concentrically distributed first annular sealing ribs, and the at least two first annular sealing ribs abut against the groove top wall of the mounting groove. The first annular sealing rib is more easily deformed under pressure than the main body part of the sealing element, and can be fully extruded against the groove top wall of the mounting groove. Moreover, the at least two first annular sealing ribs form at least two blocking functions, which can prevent the liquid in the container body from leaking from the top position of the sealing element, and the sealing effect is good.

[0011] Further, in some embodiments, the lower surface of the sealing element has at least two concentrically distributed second annular sealing ribs, and the at least two second annular sealing ribs abut against the upper surface of the annular support platform. The second annular sealing rib is more easily deformed under pressure than the main body part of the sealing element, and can be fully extruded against the upper surface of the annular support platform. Moreover, the at least two second annular sealing ribs form at least two blocking functions, which can prevent the liquid in the container body from leaking from the bottom position of the sealing element, and the sealing effect is good.

[0012] Further, in some embodiments, the lower surface of the sealing element has a third annular sealing rib near the edge of the middle part of the heat disc, and the third annular sealing rib is clamped between the inner edge of the annular support platform and the heat disc. In this way, during assembly, the inner edge of the annular support platform can buffer the contact with the heat disc, and can prevent the annular support platform from being pressed and broken.

[0013] Further, in some embodiments, the height of the first annular sealing rib ranges from 0.3mm to 1mm. With such design, on the one hand, it can avoid the first annular sealing rib being too high to separate the sealing element from the mounting groove, affecting the sealing effect at this position, and on the other hand, it can ensure that the first annular sealing rib has a certain deformation amount, thereby ensuring the sealing effect at this position.

[0014] Further, in some embodiments, the height of the second annular sealing rib is greater than or equal to 2 mm. In this way, the sealing member can absorb the tolerance caused by the deformation of the part, and ensure the stability of the sealing performance.

[0015] Further, in some embodiments, the second annular sealing rib extends obliquely towards the center of the heat disc. With this design, during the fastening process, the deformation direction of the second annular sealing rib is determined to be towards the center of the heat disc, and the situation of water leakage at the wrinkle position caused by the inconsistent deformation direction of at least two second annular sealing ribs can be avoided.

[0016] Further, in some embodiments, the angle between the side of the second annular sealing rib facing the center of the heat disc and the horizontal plane is ∠E, the angle between the side of the second annular sealing rib facing away from the center of the heat disc and the horizontal plane is ∠F, and ∠E > ∠F, ∠E ≥ 80°, and (∠E - ∠F) ≥ 15°. In this way, through actual deformation analysis, it can be ensured that the deformation direction of the second annular sealing rib is towards the center of the heat disc.

[0017] Further, in some embodiments, the lower surface of the heat disc is provided with a first connecting column, the fastener is a screw, and the fastener is inserted into the first connecting column from bottom to top through the fixing plate; wherein the head of the fastener abuts against the lower surface of the fixing plate, and the upper surface of the fixing plate abuts against the lower end surface of the first connecting column.

[0018] In these embodiments, the screw is directly connected from bottom to top between the fixing plate and the heat disc, which is convenient and fast. Moreover, the head of the screw, the fixing plate and the first connecting column abut against each other, which on the one hand is conducive to ensuring that the screw is screwed in place and cannot continue to be inserted when it reaches the abutting state, thereby ensuring that a certain extrusion force is applied to the sealing member to ensure the sealing effect of the sealing member; on the other hand, the height of the first connecting column can be designed to limit the distance between the outer peripheral edge of the heat disc and the annular support table after the screw is screwed in place, so that the sealing member is not compressed too much, and the outer peripheral edge of the heat disc is not directly extruded onto the annular support table, causing the annular support table to wear out or even break, etc. For example, in the case where the heat disc is made of metal and the container body is made of glass, the outer peripheral edge of the heat disc can be prevented from being directly extruded onto the annular support table made of glass.

[0019] Further, in some embodiments, a second connecting column is provided on the fixing plate at a position corresponding to the first connecting column, and the fastener is inserted into the first connecting column through the second connecting column; wherein the head of the fastener abuts against the lower end surface of the second connecting column, and the upper end surface of the second connecting column abuts against the lower end surface of the first connecting column.

[0020] In the embodiments, the second connecting post is arranged on the fixing plate for the fastener to pass through, and the connection between the fastener and the fixing plate is more firm, so that the fixing plate can be prevented from being damaged. Moreover, the upper end surface of the second connecting post is abutted against the lower end surface of the first connecting post, compared with directly abutting against the flat plate portion of the fixing plate, the fixing plate can also be prevented from being damaged during the screwing of the fastener. Moreover, the first connecting post does not need to be too long, and the processing is convenient.

[0021] Further, in some embodiments, the inner edge of the annular support table has an extending wall extending downward, and the portion of the fixing plate outside the extending wall is protruded upward to form an annular protruding rib, and the upper surface of the annular protruding rib is abutted against the lower surface of the annular support table.

[0022] Here, the design of the extending wall is beneficial to the centering installation of the heating disc at the lower end opening of the container body, and can prevent the heating disc from being greatly transversely shifted during the installation, and avoid that the heating disc affects the sealing effect of the sealing element due to the installation in a position offset. Moreover, the annular protruding rib is abutted against the lower surface of the annular support table, and the design of the annular protruding rib can improve the structural strength of the fixing plate, so that the fixing plate is stably pressed against the lower surface of the annular support table and is not easy to be deformed and damaged.

[0023] Further, in some embodiments, the upper surface of the annular protruding rib is an inclined surface and is inclined upward and outward in the radial direction. In this way, the abutment of the annular protruding rib against the lower surface of the annular support table can be ensured.

[0024] Specifically, the upper surface of the annular protruding rib can be designed to be in contact with the lower surface of the annular support table when the fastener is not locked in place, so that as the fastener is locked, the inclined upper surface of the annular protruding rib has a tendency to increase the contact area, and can better extrude the annular support table, thereby improving the installation stability of the heating disc. Of course, the upper surface of the annular protruding rib can also be designed to be in contact with the lower surface of the annular support table and gradually pressed tightly as the fastener is locked.

[0025] Further, in some embodiments, the fixing plate is a plastic part, and the distance between the position where the fixing plate is abutted against the lower surface of the annular support table and the fastener in the horizontal direction is between 7 mm and 35 mm. In this way, the installation stability of the heating disc can be ensured. Moreover, under the same extrusion force caused by the fastener, the sealing element can be ensured to be extruded enough to achieve sealing, and a part of the deformation amount can be absorbed by the deformation of the plastic material of the fixing plate itself, so that the sealing element is not excessively compressed, thereby avoiding that the edge of the heating disc is pressed against the annular support table.

[0026] Furthermore, in some embodiments, the heating plate includes: a plate body, the edge of which extends radially outward to above the annular support platform, and a mounting groove disposed on the plate body; heating tubes distributed in a ring on the lower surface of the plate body, the heating tubes extending into the lower opening of the container body, and fasteners connected to the portion of the plate body located outside the heating tubes.

[0027] During actual production, the dimensions of both the fixing plate and the heating plate will deform to some extent. For the same degree of deformation, the larger the horizontal distance L3 from the location of the fastener to the sealing position of the seal, the greater the deformation during assembly and fixing. After the fastener is tightened, the sealing effect of the seal will be less stable. Conversely, the smaller L3, the smaller the deformation during assembly and fixing, and the better the sealing effect of the seal after the fastener is tightened. Therefore, in this embodiment, both the fastener and the seal are located outside the annular ring of the heating tube, without needing to cross the heating tube. This helps to minimize the horizontal distance L3 from the location of the fastener to the sealing position of the seal, thereby ensuring a stable sealing effect and guaranteeing the seal between the heating plate and the annular support platform.

[0028] A second aspect of this utility model provides a liquid heating device, comprising: a base; and a liquid heating container as described in any of the above embodiments, the liquid heating container being disposed on the base.

[0029] The liquid heating device provided in this embodiment has the beneficial effects of any of the above embodiments due to having the liquid heating container of any of the above embodiments, which will not be described in detail here.

[0054] The embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1 to 8 The embodiments of the present application provide a liquid heating container. The embodiments of the present application provide a liquid heating container.

[0055] As Figures 1 to 5 shown, an aspect of the utility model provides a kind of liquid heating container, and the liquid heating container includes: container body 100, the upper and lower ends of container body 100 have opening, the lower end of container body 100 has annular support table 110 extending radially inward;Heating disc 200, setting at the lower end opening of container body 100, and the edge of heating disc 200 extends radially outward to the upper of annular support table 110;Sealing element 300, clamped between the edge of heating disc 200 and the upper surface of annular support table 110;Fixed plate 400, setting below annular support table 110;Fastener 500, fastener 500 is connected fixed plate 400 and heating disc 200 in the hollow area of the radial inner side of annular support table 110, to clamp heating disc 200 and fixed plate 400 on the two sides of annular support table 110, and sealing element 300 is clamped between heating disc 200 and the upper surface of annular support table 110.

[0056] The liquid heating container provided by the aspect embodiment, sealing element 300 is located in the inner side of container body 100, clamped between the edge of heating disc 200 and the upper surface of annular support table 110, sealing element 300 will not be exposed, can improve the appearance of liquid heating container, improve user experience.And, by fastener 500 connecting fixed plate 400 and heating disc 200 makes them clamp on the two sides of annular support table 110, can extrude sealing element 300, so that sealing element 300 is tightly fitted with the edge of heating disc 200 and annular support table 110, to facilitate guaranteeing the connection sealing property of container body 100 and heating disc 200.Moreover, after fastener 500 tension heating disc 200 and fixed plate 400, here makes heating disc 200 press against the upper surface of annular support table 110 by sealing element 300, fixed plate 400 press against the lower surface of annular support table 110, and heating disc 200 installation stability is good.

[0057] In specific installation process, sealing element 300 can be installed on heating disc 200 in advance, heating disc 200 is inserted into container body 100 from the upper end opening of container body 100, so that the edge of heating disc 200 is located above annular support table 110, and then fixed plate 400 is placed below container body 100, and fastener 500 is used to connect fixed plate 400 and heating disc 200, to provide extrusion force for sealing element 300, so that sealing element 300 is clamped between the edge of heating disc 200 and annular support table 110 under pressure, and the fixation of heating disc 200 is realized.In this case, the outer diameter of heating disc 200 is less than the inner diameter of the upper end opening of container body 100 by default.

[0058] Further, in some embodiments, as Figure 2 , Figure 4 And Figure 5As shown, the lower surface of the heating disc 200 is provided with a first connecting column 230, and the fastener 500 is a screw, which is inserted into the first connecting column 230 from bottom to top through the fixing plate 400; wherein the head of the fastener 500 abuts against the lower surface of the fixing plate 400, and the upper surface of the fixing plate 400 abuts against the lower end surface of the first connecting column 230.

[0059] In these embodiments, the screw is directly used to connect the fixing plate 400 and the heating disc 200 from bottom to top, which is convenient and fast. Moreover, the head of the screw, the fixing plate 400 and the first connecting column 230 are in abutment with each other, which on the one hand helps to ensure that the screw is screwed in place, and cannot continue to be inserted when it is in abutment, thereby ensuring that a certain extrusion force is applied to the sealing element 300, and ensuring the sealing effect of the sealing element 300; on the other hand, the height of the first connecting column 230 can be designed to limit the distance between the edge of the heating disc 200 and the annular support table 110 after the screw is screwed in place, so that the sealing element 300 is not compressed too much, and the edge of the heating disc 200 is directly extruded onto the annular support table 110, which can cause the annular support table 110 to wear or even break, etc. For example, in the case where the heating disc 200 is made of metal and the container body 100 is made of glass, the edge of the heating disc 200 can be prevented from being directly extruded onto the annular support table 110 made of glass.

[0060] Further, as shown in Figure 2 , Figure 4 and Figure 5 , the fixing plate 400 is provided with a second connecting column 410 at a position corresponding to the first connecting column 230, and the fastener 500 is inserted into the first connecting column 230 through the second connecting column 410; wherein the head of the fastener 500 abuts against the lower end surface of the second connecting column 410, and the upper end surface of the second connecting column 410 abuts against the lower end surface of the first connecting column 230. Such design makes the connection between the fastener 500 and the fixing plate 400 more secure, which can prevent the fixing plate 400 from being damaged. Moreover, the abutment between the upper end surface of the second connecting column 410 and the lower end surface of the first connecting column 230 can also prevent the fixing plate 400 from being damaged during the screwing of the fastener 500, compared with the abutment between the flat plate portion of the fixing plate 400 and the first connecting column 230. Moreover, the length of the first connecting column 230 does not need to be too long, which is convenient for processing.

[0061] As an example, as shown in Figure 1 and Figure 2As shown, the fixing plate 400 is annular, and five second connecting columns 410 are arranged on the inner side wall of the fixing plate 400. In order to improve the strength of the second connecting column 410, a reinforcing rib 430 is additionally arranged between the outer periphery of the second connecting column 410 and the lower surface of the fixing plate 400. The second connecting column 410 can have a through hole extending upward and downward, or the second connecting column 410 can be a threaded column. The first connecting column 230 is a threaded column, and five first connecting columns 230 are distributed at intervals around the heat pipe 220 in the circumferential direction. Five screws are inserted into the second connecting column 410 and the first connecting column 230 one by one.

[0062] Further, in some embodiments, as shown in Figure 4 and Figure 5 As shown, the inner edge of the annular support table 110 has an extension wall 120 extending downward, and the portion of the fixing plate 400 located outside the extension wall 120 protrudes upward to form an annular protruding rib 420, and the upper surface of the annular protruding rib 420 abuts against the lower surface of the annular support table 110.

[0063] Here, the design of the extension wall 120 is beneficial for the heat disc 200 to be installed in the center of the lower end opening of the container body 100, which can prevent the heat disc 200 from moving transversely greatly during installation, and avoid affecting the sealing effect of the sealing element 300 due to the installation of the heat disc 200 being out of position. Moreover, by abutting the annular protruding rib 420 against the lower surface of the annular support table 110, the design of the annular protruding rib 420 can improve the structural strength of the fixing plate 400, so that the fixing plate 400 is stably pressed against the lower surface of the annular support table 110 and is not easy to deform and damage.

[0064] Further, as shown in Figure 5 and Figure 6 As shown, the upper surface of the annular protruding rib 420 is an inclined surface and inclines upward and outward in the radial direction. In this way, the annular protruding rib 420 can be ensured to abut against the lower surface of the annular support table 110.

[0065] Specifically, the upper surface of the annular protruding rib 420 can be in contact with the lower surface of the annular support table 110 when the fastener 500 is not locked in place. As the fastener 500 is locked, the inclined upper surface of the annular protruding rib 420 has a tendency to increase the contact area, which can better extrude the annular support table 110, thereby improving the installation stability of the heat disc 200. Of course, the upper surface of the annular protruding rib 420 can also be in contact with the lower surface of the annular support table 110 and gradually pressed tightly as the fastener 500 is locked.

[0066] Further, as shown in Figure 6As shown, the fixing plate 400 is a plastic piece, and the distance L1 between the position where the fixing plate 400 abuts against the lower surface of the annular support table 110 and the fastener 500 in the horizontal direction is between 7 mm and 35 mm. In this way, the installation stability of the heat disc 200 can be ensured. Moreover, under the same extrusion force caused by the fastener 500, the sealing piece 300 can be guaranteed to be extruded enough to achieve sealing, and a part of the deformation amount can be absorbed by the deformation of the plastic material of the fixing plate 400 itself, so that the sealing piece 300 will not be compressed too much, thereby avoiding that the edge of the heat disc 200 is pressed against the annular support table 110.

[0067] In addition, the fixing plate 400 is a plastic piece, which is low in cost, and the fixing plate 400 can produce a small deformation under pressure and will not cause wear to the heat disc 200 and the annular support table 110.

[0068] As an example, the distance L1 between the position where the fixing plate 400 abuts against the lower surface of the annular support table 110 and the fastener 500 in the horizontal direction is 10 mm or 20 mm or 30 mm.

[0069] Further, in some embodiments, as shown in Figure 5 and Figure 6 The heat disc 200 includes: a disc body 210, the edge of the disc body 210 extending radially outward above the annular support table 110; and a heat pipe 220, which is annularly distributed on the lower surface of the disc body 210, the heat pipe 220 extending into the lower end opening of the container body 100, and the fastener 500 being connected to the part of the disc body 210 outside the heat pipe 220.

[0070] Because in the actual production process, the size of the fixing plate 400 and the heat disc 200 will have a certain deformation, and the same deformation degree, the greater the distance L3 between the position where the fastener 500 is located and the sealing position of the sealing piece 300 in the horizontal direction, the greater the deformation amount of the assembly fixation, and the more unstable the sealing effect of the sealing piece 300 after the fastener 500 is fastened. The smaller the distance L3, the smaller the deformation amount of the assembly fixation, and the better the sealing effect of the sealing piece 300 after the fastener 500 is fastened. Therefore, in the present embodiment, the fastener 500 and the sealing piece 300 are both located outside the annular heat pipe 220, and do not need to cross the heat pipe 220, which is conducive to making the distance L3 between the position where the fastener 500 is located and the sealing position of the sealing piece 300 in the horizontal direction smaller, so that the sealing piece 300 has a stable sealing effect, and the sealing between the heat disc 200 and the annular support table 110 is ensured.

[0071] For the installation position of the sealing piece 300, further, in some embodiments, as shown in Figure 1 , Figure 5 and Figure 6As shown, the edge of the heating disc 200 is raised upward to form an open downward mounting groove 211, and a part of the sealing member 300 is embedded in the mounting groove 211. In this way, on the one hand, the sealing member 300 can be quickly installed in place in the position of the mounting groove 211, improving assembly efficiency; on the other hand, the mounting groove 211 can limit the sealing member 300, avoiding the sealing member 300 from moving transversely during compression, ensuring that it can be accurately and extensively pressed onto the annular support table 110, and the mounting groove 211 can also contact the sealing member 300 on multiple surfaces, thereby improving the sealing effect of the sealing member 300.

[0072] In addition, since the sealing member 300 is mostly hidden in the mounting groove 211, even when looking at the inside bottom of the container body 100, it is not easy to perceive the existence of the sealing member 300, and the visual effect is good.

[0073] As an example, the sealing member 300 is a sealing ring made of silica gel, and the sealing ring is elastically compressed and assembled in the space between the mounting groove 211 and the upper surface of the annular support table 110.

[0074] As an example, in the case where the heating disc 200 includes a disc body 210, the mounting groove 211 is arranged at the edge of the lower surface of the disc body 210.

[0075] Further, in some embodiments, as shown in Figure 5 and Figure 6 The distance L2 between the outer peripheral edge of the heating disc 200 and the upper surface of the annular support table 110 in the vertical direction is between 0.5 mm and 2 mm.

[0076] In these embodiments, after the fastener 500 fastens the fixed plate 400 and the heating disc 200 together, the distance L2 between the outer peripheral edge of the heating disc 200 and the upper surface of the annular support table 110 in the vertical direction is between 0.5 mm and 2 mm, which can avoid the outer peripheral edge of the heating disc 200 directly pressing down on the annular support table 110, causing the annular support table 110 to be rubbed or damaged, and can also ensure that the sealing member 300 is sufficiently compressed, thereby ensuring the sealing effect.

[0077] Specifically, as shown in Figure 5 and Figure 6 In the case where the outer peripheral edge of the heating disc 200 forms the above-mentioned mounting groove 211, the distance L2 between the bottom of the groove side wall of the mounting groove 211 and the upper surface of the annular support table 110 is between 0.5 mm and 2 mm.

[0078] As an example, the distance L2 between the outer peripheral edge of the heating disc 200 and the upper surface of the annular support table 110 in the vertical direction is 0.5 mm or 1 mm or 1.5 mm.

[0079] For the specific structure of the sealing member 300, further, in some embodiments, as shown in Figure 5 , Figure 7 and Figure 8 , the upper surface of the sealing member 300 has at least two rings of first annular sealing ribs 310 arranged concentrically, and the at least two rings of first annular sealing ribs 310 abut against the lower surface of the heating disc 200. The first annular sealing ribs 310 are more easily deformed under pressure than the main body part of the sealing member 300, can be fully pressed against the lower surface of the heating disc 200, and the at least two rings of first annular sealing ribs 310 form at least two barriers, which can prevent the liquid in the container body 100 from leaking out from the top position of the sealing member 300, and the sealing effect is good.

[0080] Specifically, in the case where the mounting groove 211 is formed at the edge of the heating disc 200, the at least two rings of first annular sealing ribs 310 abut against the groove top wall of the mounting groove 211.

[0081] Further, the height H1 of the first annular sealing ribs 310 is in the range of 0.3mm to 1mm. In this way, on the one hand, it can be avoided that the first annular sealing ribs 310 are too high to separate the sealing member 300 from the heating disc 200, affecting the sealing effect at this position, and on the other hand, it can be ensured that the first annular sealing ribs 310 have a certain deformation amount, thereby ensuring the sealing effect at this position.

[0082] For example, the height H1 of the first annular sealing ribs 310 is 0.4mm or 0.6mm or 0.8mm.

[0083] Further, in some embodiments, as shown in Figure 5 , Figure 7 and Figure 8 , the lower surface of the sealing member 300 has at least two rings of second annular sealing ribs 320 arranged concentrically, and the at least two rings of second annular sealing ribs 320 abut against the upper surface of the annular support table 110. The second annular sealing ribs 320 are more easily deformed under pressure than the main body part of the sealing member 300, can be fully pressed against the upper surface of the annular support table 110, and the at least two rings of second annular sealing ribs 320 form at least two barriers, which can prevent the liquid in the container body 100 from leaking out from the bottom position of the sealing member 300, and the sealing effect is good.

[0084] Further, as shown in Figure 8 , the height H2 of the second annular sealing ribs 320 is greater than or equal to 2mm. In this way, it can be ensured that the sealing member 300 can absorb the tolerance caused by the deformation of the parts, and ensure the stability of the sealing performance.

[0085] For example, the height H2 of the second annular sealing ribs 320 is 2mm or 3mm or 4mm.

[0086] Further, as shown in Figure 5 , Figure 7 and Figure 8 , the second annular sealing rib 320 extends obliquely towards the center of the heating disc 200. In this way, the deformation direction of the second annular sealing rib 320 during fastening is determined, and the second annular sealing rib 320 will deform towards the center of the heating disc 200, so that the situation that water leaks from the wrinkle position due to inconsistent deformation directions of the at least two second annular sealing ribs 320 can be avoided.

[0087] Of course, in other embodiments, the second annular sealing rib 320 can also extend obliquely away from the center of the heating disc 200.

[0088] Further, as shown in Figure 5 and Figure 8 , the angle between the side of the second annular sealing rib 320 facing the center of the heating disc 200 and the horizontal plane is ∠E, and the angle between the side of the second annular sealing rib 320 facing away from the center of the heating disc 200 and the horizontal plane is ∠F, which satisfy ∠E> ∠F, ∠E≥ 80°, and (∠E- ∠F)≥ 15°. In this way, through actual deformation analysis, it can be ensured that the deformation direction of the second annular sealing rib 320 is towards the center of the heating disc 200.

[0089] Further, as shown in Figure 5 , Figure 7 and Figure 8 , the lower surface of the sealing member 300 has a third annular sealing rib 330 near the edge of the middle part of the heating disc 200, and the third annular sealing rib 330 is clamped between the inner edge of the annular support table 110 and the heating disc 200. In this way, during assembly, the inner edge of the annular support table 110 can buffer the contact with the heating disc 200, so that the annular support table 110 can be prevented from being crushed.

[0090] Further, in some embodiments, the container body 100 is a glass container body, which has good appearance effect. The heating disc 200 includes a heating tube 220 and a disc body 210 made of metal.

[0091] The second aspect embodiment of the utility model provides a liquid heating device, comprising: a base; and the liquid heating container of any one of the above embodiments, the liquid heating container is arranged on the base.

[0092] The liquid heating device provided by the embodiment has the liquid heating container of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0093] Further, in some embodiments, the liquid heating container is fixed on the top of the base. At this time, the control board and other components are arranged inside the base.

[0094] Of course, the liquid heating container can also be detachably placed on the base. At this time, a lower coupler can be arranged on the base, and an upper coupler is arranged below the heating disc 200, the upper coupler is electrically connected with the heating disc 200, and the heating disc 200 is powered by the cooperation of the lower coupler and the upper coupler.

[0095] Further, in some embodiments, the liquid heating device is an electric kettle or a health pot or a tea kettle, etc.
