[0030] Figure 1 A structure diagram of a heating disc sealing structure mounting position is shown. Figure 2 A structure diagram of a heating disc sealing structure mounting position is shown. Figure 1 An enlarged structure diagram of a part is shown. Figure 1 And Figure 2 The utility model discloses a heating disc sealing structure.

[0031] The heating disc sealing structure is located between the kettle body 1 and the bottom cover 2.

[0032] The metal disc 4 is horizontally installed above the heating disc 8. The metal disc 4 is arranged at the bottom of the kettle body 1 and abuts against the step structure 3, and the horizontal height of the upper surface of the metal disc 4 is close to the horizontal height of the upper surface of the step structure 3, so that no obvious step and gap is formed at the bottom in the kettle body 1, and the bottom in the kettle body 1 is convenient to clean. The first sealing ring 5 is located between the step structure 3 and the metal disc 4, and the metal disc 4 completely shields the first sealing ring 5, avoiding the exposure of the first sealing ring 5.

[0033] The first sealing ring 5 abuts against one side of the metal disc 4 and the step structure 3 respectively, so that the first sealing ring 5 is completely limited and fixed, and the continuous sealing between the step structure 3 and the metal disc 4 is maintained.

[0034] The support 6 supports the second sealing ring 7 to contact the other side of the step structure 3, and the support 6 tightly fixes the second sealing ring 7 on the other side of the step structure 3, so that the continuous sealing between the kettle body 1 and the bottom cover 2 is maintained.

[0035] The step structure 3 comprises a first step 31 and a second step 32 which are connected in sequence and downwardly transition. The height difference between the height position of the first step 31 and the height position of the second step 32 is 2.4-3.5mm.

[0036] Exemplarily, the bending angle of the first step 31 is an obtuse angle. The contact area of the first step 31 and the first sealing ring 5 is increased, so that the metal disc 4 can completely realize sealing when pressing the first sealing ring 5.

[0037] Exemplarily, the bending angle of the second step 32 is a right angle. When the support 6 supports the second sealing ring 7 to contact the second step 32, the second sealing ring 7 can be tightly pressed on the step structure 3, and loosening does not occur.

[0038] The metal disc 4 abuts against the first step 31, and the first sealing ring 5 is completely shielded.

[0039] The first sealing ring 5 is bent and attached to one side of the second step 32, and the second sealing ring 7 is bent and attached to the other side of the first step 31 and the other side of the second step 32. By locating the first sealing ring 5 and the second sealing ring 7 on both sides of the stepped structure 3, double sealing between the kettle body 1 and the bottom cover 2 is achieved.

[0040] The second step 32 is provided with a ring part 33 at the end thereof, and the ring part 33 is located at the lower end of the second step 32. One end of the second sealing ring 7 is clamped between the kettle body 1 and the bottom cover 2, and the kettle body 1 and the bottom cover 2 hold the one end of the second sealing ring 7. The other end of the second sealing ring 7 abuts against the ring part 33 and is supported and fixed by the bracket 6, so that the force on the position where the other end of the second sealing ring 7 abuts against the ring part 33 is larger, and the other end of the second sealing ring 7 is firmly fixed. By fixing the two ends of the second sealing ring 7, curling and lifting of the two ends of the second sealing ring 7 is avoided, and the sealing effect of the second sealing ring 7 is ensured.

[0041] The metal disc 4 is inwardly bent at the edge thereof to form a bent edge 41, the angle between the bent edge 41 and the metal disc 4 is 1.5-2.5°, the overall thickness of the bent edge 41 and the metal disc 4 is 1.3-2.5mm, and the width of the bent edge 41 is 1.5-3.5mm.

[0042] The bent edge 41 and the metal disc 4 form an angle, so that the bent edge 41 forms a downward pressure on the first sealing ring 5 to fix the first sealing ring 5.

[0043] By limiting the overall thickness of the bent edge 41 and the metal disc 4 and the width of the bent edge 41 within a reasonable range, bending processing is facilitated while ensuring a certain structural strength. If the overall thickness of the bent edge 41 and the metal disc 4 is small and the width of the bent edge 41 is narrow, the bending processing of the metal disc 4 is difficult to form, the gap between the first sealing ring 5 and the bottom of the kettle body 1 is small, and glue leakage is easy, which cannot ensure the sealing performance. If the overall thickness of the bent edge 41 and the metal disc 4 is large and the width of the bent edge 41 is wide, the bending resistance of the bent edge 41 decreases, and the bent edge 41 is easy to deform and lift, causing glue leakage.

[0044] The first sealing ring 5 abuts against the end face of the bent edge 41, and the bent edge 41 is in a state of tension. The bent position of the metal disc 4 abuts against the first step 31 to avoid position loosening of the metal disc 4 and the first step 31.

[0045] A first step part 51 is formed on one side of the first sealing ring 5 close to the metal disc 4. The first step part 51 abuts against the metal disc 4 and the bent edge 41, respectively.

[0046] For example, the number of the first step parts 51 can be one group or multiple groups. When the first step part 51 is multiple groups, the first sealing ring 5 can form multiple sealing lines to enhance the sealing performance of the first sealing ring 5.

[0047] The first table part 51 in the embodiment is in two groups, and a gap is formed between the two groups of first table parts 51. One group of first table parts 51 abuts against the metal disc 4 and the folded edge 41 respectively, and the other group of first table parts 51 abuts against the metal disc 4.

[0048] The recess 34 is formed between the first step 31 and the second step 32. The second table part 52 is formed on the first sealing ring 5 near one side of the step structure 3, and the second table part 52 is embedded in the recess 34.

[0049] For example, the number of second table parts 52 can be one group or multiple groups. The number of recesses 34 corresponds to the number of second table parts 52. When the first table parts 51 are in multiple groups, the first sealing ring 5 is embedded in multiple positions between the first step 31 and the second step 32, thereby enhancing the position limitation of the first sealing ring 5.

[0050] The second table part 52 in the embodiment is in two groups, and a gap is formed between the two groups of second table parts 52. The second table part 52 is embedded in the corresponding recess 34.

[0051] The support edge 61 is horizontally arranged around the upper end of the support 6. The support 6 and the support edge 61 abut against the bent position of the second sealing ring 7. Since the bending angle of the second step 32 is a right angle, the bent position of the second sealing ring 7 is also a right angle. The support 6 can abut against the bent position of the second sealing ring 7 from the vertical direction, and the support edge 61 can abut against the bent position of the second sealing ring 7 from the horizontal direction, thereby tightly pressing and fixing the second sealing ring 7 on the other side of the step structure 3, avoiding loosening of the second sealing ring 7, and realizing continuous sealing.

[0052] The support 6 forms the curved part 62, so that the support 6 forms an inward elastic pushing force. For example, the cross section of the curved part 62 is circular arc shape. The curved part 62 is bent downward, and the curved part 62 forms the elastic pushing force to push the support 6 and the support edge 61 to tightly press the bent position of the second sealing ring 7.

[0053] The support 6 is fixed on the heat disc 8 through the fixing member 63. For example, the fixing member 63 is a bolt. After the fixing member 63 passes through the support 6 from below, it is screwed into the heat disc 8 upward. After the fixing member 63 is tightened, the support 6 is fixed below the heat disc 8, avoiding loosening of the support 6, so that the support 6 and the support edge 61 can continuously tightly press the bent position of the second sealing ring 7, and the sealing performance of the second sealing ring 7 is maintained.

[0054] Any combination of the technical features of the above embodiments can be made. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered as the scope of the present disclosure.

[0055] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model.
