[0002] The heating disc is an important component of the water boiler, which heats the liquid in the kettle body. The heating disc can be fixed inside or outside the kettle body.
[0003] When the heating disc is arranged inside the kettle body, it is difficult to completely remove the scale or residues during cleaning due to the fixed position and complex structure of the heating disc, which may affect the water quality after long-term accumulation. In addition, the heating disc is made of various metals or composite materials, which may produce harmful substances during the heating process and cause safety problems. Therefore, the existing water boiler tends to arrange the heating disc outside the water boiler. When the heating disc is arranged outside the kettle body, an additional fixing structure is needed to connect the heating disc and the kettle body, and the connection strength and stability between the heating disc and the kettle body are poor, especially when the kettle body is smooth.
[0004] It should be noted that the information disclosed in the above background section is only used to enhance the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those skilled in the art. SUMMARY

[0034] Figure 1 An exploded structural schematic diagram of the kettle fixing structure of an embodiment of the present disclosure is shown. Figure 2 A vertical sectional structural schematic diagram of the kettle fixing structure of an embodiment of the present disclosure is shown. Figure 3 A local enlarged view of the kettle fixing structure of an embodiment of the present disclosure at A is shown. Please refer to Figure 1 , Figure 2 and Figure 3 The kettle fixing structure includes a kettle body 1, a fixing ring 2, a fixing sleeve 5 and a heating disc 3. The kettle body 1 has an internal cavity 11 for containing liquid. The fixing ring 2 is sleeved on the kettle body 1. The fixing sleeve 5 is sleeved on the fixing ring 2. The fixing sleeve 5 is detachably connected to the fixing ring 2. The heating disc 3 is arranged in the fixing sleeve 5. Specifically, a heat-conducting surface 31 of the heating disc 3 contacts the kettle body 1. A heating tube 32 is arranged on the heating disc 3. The heating tube 32 is connected to a power source along a barrel hole 53 of the fixing sleeve 5.
[0035] The inner wall of the fixed sleeve 5 is protruded to form a limiting part 52. The heating disc 3 is arranged between the kettle body 1 and the limiting part 52, and the elastic gasket 4 is arranged between the heating disc 3 and the limiting part 52. The elastic gasket 4 absorbs impact and vibration energy, effectively reduces the vibration transmitted by the fixed sleeve 5 to the heating disc 3 when the kettle is impacted. Avoid frequent vibration to loosen the connection between the fixed sleeve 5 and the fixed ring 2, and affect the stability of the connection between the heating disc 3 and the kettle body 1. At the same time, the elastic gasket 4 makes the heating disc 3 and the fixed sleeve 5 elastically connected, effectively offsets the deformation and stress generated when the heating disc 3 is heated / cooling, and avoids damaging the connection structure between the kettle body 1 and the fixed sleeve 5. The limiting part 52 fixes the position of the heating disc 3, and the heating disc 3 heats the kettle body 1. The entire heating disc 3 is arranged in the fixed sleeve 5, and the fixed sleeve 5 surrounds and fixes the position of the heating disc 3. The fixed sleeve 5 limits the degrees of freedom of the heating disc 3 in multiple directions, and the contact area between the fixed sleeve 5 and the heating disc 3 is large, so as to stably support and fix the position of the heating disc 3. The support force required by the heating disc 3 is annularly dispersed to the fixed sleeve 5, the local stress concentration is reduced, and the stability of the fixed heating tube 32 is improved.
[0036] Preferably, the neck 12 is arranged at the end of the fixed sleeve 5, which facilitates the processing of the neck 12, avoids the main body part of the fixed sleeve 5 being arranged beyond the position of the neck 12, and wastes raw materials.
[0037] More preferably, the fixed ring 2 is provided with external threads 21. The barrel wall of the fixed sleeve 5 is provided with internal threads 51. The fixed sleeve 5 is threadedly connected to the fixed ring 2 through the internal threads 51 and the external threads 21. The fastening is achieved through the engagement between the internal threads 51 and the external threads 21, which can withstand large axial tensile force and transverse shear force, and has strong bearing capacity. The cooperation between the threads has self-locking property, has strong anti-loose ability, is suitable for vibration or impact environment, and improves the stability of the fixed heating disc 3.
[0038] In the embodiment, the fixed sleeve 5 is an independent part. In some other embodiments, the fixed sleeve 5 can also be a partial structure of a whole part.
[0039] In the embodiment, the fixed ring 2 is an independent part. In some other embodiments, the fixed ring 2 can also be integrally formed with the kettle body 1. For example, when the kettle body 1 is made of metal or other materials that can be processed into threads, the fixed ring 2 and the external threads thereof can be integrally arranged with the kettle body 1.
[0040] Please refer to Figure 2 and Figure 3, one end of the kettle body 1, the outer diameter of which is contracted to form a neck 12. The fixing ring 2 is sleeved on the neck 12. The neck 12 is provided with a limiting protrusion 121. The height difference between the main body part of the kettle body 1 and the neck 12 is connected by a drop surface 122. The fixing ring 2 is arranged between the drop surface 122 and the limiting protrusion 121. The cooperation between the drop surface 122 and the limiting protrusion 121 limits the position of the fixing ring 2 on the neck 12, avoids the sliding deviation of the fixing ring 2 along the neck 12, and ensures that the heating disc 3 always uniformly heats the kettle body 1. Uniform heating can significantly improve the heat conduction efficiency, shorten the boiling time, and improve the user's experience.
[0041] Preferably, the limiting part 52 is a complete ring. The ring-shaped limiting part 52 increases the contact area between the limiting part 52 and the heating disc 3, and the fixing sleeve 5 supports the heating disc 3 through the ring-shaped limiting part 52, so that the weight of the heating disc 3 can be uniformly transmitted to the fixing sleeve 5 along the ring-shaped limiting part 52, and the fixing sleeve 5 more stably supports the heating disc 3. Correspondingly, in some embodiments, the limiting protrusion 121 and the shoulder 521 can also be a whole continuous circular ring type, which makes the force transmission more uniform and improves the overall stability of the kettle fixing structure.
[0042] Please refer to Figure 2 and Figure 3 , the limiting part 52 extends away from the end of the fixing sleeve 5 and towards the heating disc 3. The elastic gasket 4 is arranged between the fixing sleeve 5 and the shoulder 521. The position of the elastic gasket 4 is limited by the shoulder 521 to avoid moving away from the preset position and affecting the damping effect.
[0043] More preferably, the height of the shoulder 521 extends along the axis of the fixing sleeve 5 between 1 / 3 and 1 / 2 of the height of the elastic gasket 4, and correspondingly, the compression deformation amount of the elastic gasket 4 is 20% to 50% of the original thickness. On the one hand, the maximum compression stroke of the elastic gasket 4 is limited by the shoulder 521 to avoid excessive local stress of the elastic gasket 4. On the other hand, the height of the shoulder 521 is lower than the height of the elastic gasket 4 to ensure that the elastic gasket 4 has enough deformation stroke to reduce the transmission of vibration between the fixing sleeve 5 and the heating disc 3.
[0044] Figure 4 The figure shows the three-dimensional structure of the fixing ring in the kettle fixing structure of an embodiment of the present disclosure. Please refer to Figure 2 , Figure 3 and Figure 4The fixed ring 2 is provided with a cutout 22 which cuts the fixed ring 2, and the interval of the cutout 22 is between 2-5 mm. The cutout 22 is arranged so that the fixed ring 2 does not need to move along the axial direction of the neck 12 to be sleeved on the neck 12, and the fixed ring 2 can be opened along the cutout 22, and then the fixed ring 2 is moved perpendicularly to the neck 12 to be sleeved on the neck 12. The assembly process between the fixed ring 2 and the kettle body 1 is greatly simplified, and the maintenance cost of the kettle fixing structure is reduced.
[0045] Preferably, the cutout 22 is V-shaped, and the opening angle of the V-shaped cutout 22 is 60°-120°. When the fixed sleeve 5 and the fixed ring 2 are screwed, the fixed ring 2 is extruded by the fixed sleeve 5, at which time the V-shaped cutout 22 changes from opening to closing. The V-shaped geometry of the cutout 22 reduces the friction when the fixed ring 2 slides around the neck 12. When the cutout 22 is closed, the contact area of the two V-shaped sections of the cutout 22 gradually increases, thereby gradually increasing the resistance when the fixed ring 2 is closed, avoiding the sudden change in resistance when the fixed ring 2 is closed during the screwing of the fixed sleeve 5 and the fixed ring 2, thereby improving the smoothness of the screwing of the fixed sleeve 5 and the fixed ring 2 and optimizing the operation experience.
[0046] Figure 5 A partial enlarged view of the kettle fixing structure of an embodiment of the present disclosure at A is shown, please refer to Figure 2 and Figure 5 In some embodiments, the fixed ring 2 is provided with a female stop 23 extending away from the surface of the kettle body 1. The inner surface of the fixed sleeve 5 is provided with a male stop 54. When the fixed sleeve 5 is sleeved on the kettle body 1, the male stop 54 is arranged between the female stop 23 and the kettle body 1. The male stop 54 and the female stop 23 can be integrally formed with the main body structure, which simplifies the processing steps of the fixed ring 2 and the fixed sleeve 5 and reduces the production cost. Moreover, the stopper clamping structure is compact and occupies small space, which is suitable for household kettles.
[0047] Preferably, the contact surface between the male stop 54 and the female stop 23 can be a bevel which forms an acute angle with the axis of the kettle body 1, and the bevel is inclined to the side of the heating disc 3 away from the end of the kettle body 1. When the heating disc 3 is heated to cause thermal expansion, the bevel facilitates the sliding between the fixed sleeve 5 and the fixed ring 2 to adapt to the change in volume.
[0048] The specific working process of the kettle fixing structure is as follows:
[0049] When assembling the heat disc 3, firstly, the fixing ring 2 is opened along the position of the cut 22, the fixing ring 2 is moved perpendicularly to the axis of the neck 12, and the neck 12 enters the fixing ring 2 along the cut 22. Then, the fixing ring 2 is closed along the position of the cut 22, and the fixing ring 2 is sleeved on the neck 12. Then, the heat disc 3 is moved into the fixing sleeve 5, the heat pipe 32 is close to one side of the limiting part 52, and the elastic gasket 4 is arranged between the heat disc 3 and the limiting part 52. Finally, the fixing sleeve 5 and the fixing ring 2 are clamped, and the fixing of the heat disc 3 is completed.
[0050] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.
[0051] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
