Description

Technical Field

[0001] The present application relates to the technical field of kettles, and in particular to a kettle. Background Art

[0002] Kettles are common household items. There are many types of kettles on the market with different structures and functions, giving consumers a wide range of choices, such as thermos kettles, teapots, kettles, health kettles, and so on.

[0003] Generally speaking, the outer shell of a kettle body can be made of metal materials such as stainless steel, but metal materials have weak drop resistance and wear resistance. When the kettle falls, the kettle body is easily bumped and scratched or even cracked.

[0004] In order to solve the above problems, the prior art adds a plastic shell to the outside of the kettle, and uses the plastic shell as a protective component to protect the kettle body. Based on the analysis of the examples, it is found that the bottom of the kettle is more likely to be damaged as it is the part that bears the impact after the kettle falls. Therefore, the prior art often connects an additional plastic base to the bottom of the kettle, which can effectively protect the kettle body. However, in actual use, the plastic base of the existing kettle may fall off even if it is not bumped, and it is often difficult for users to put the plastic base back on their own after it falls off, which results in the kettle being unable to be used normally because it cannot be placed normally and stably. Therefore, how to improve the connection stability between the plastic base and the stainless steel kettle body is a technical problem to be solved in the field of kettle technology. Utility Model Content

[0005] The present application provides a kettle, which helps to improve the connection stability between the plastic base and the kettle body, so as to solve the technical problem that the base of the current kettle, especially the plastic base, is easy to fall off from the bottom of the kettle body.

[0006] The technical solution adopted in this application is:

[0007] A kettle, comprising a kettle body and a base; wherein the base comprises a clamping wall, the clamping wall and the kettle body abut against each other to fix the base and the kettle body relatively; the clamping wall is connected to a maintaining member, the rigidity of the maintaining member is greater than the rigidity of the clamping wall, and the maintaining member abuts against the clamping wall to maintain the clamping wall in a state of fitting the kettle body.

[0008] The kettle provided in this application also includes the following additional technical features:

[0009] The clamping wall includes an outer ring wall and an inner ring wall connected to the inner side of the outer ring wall, and the maintaining member is arranged in the gap formed between the outer ring wall and the inner ring wall; along the radial direction of the kettle body, the maintaining member presses against the inner surface of the outer ring wall and the outer surface of the inner ring wall.

[0010] The gap formed between the outer ring wall and the inner ring wall is configured as a tapered structure that gradually narrows from top to bottom.

[0011] A reinforcing structure is connected to the inner side of the outer ring wall, and the reinforcing structure is arranged circumferentially along the outer ring wall.

[0012] The reinforcing structure includes reinforcing ribs connected between the inner ring wall and the outer ring wall.

[0013] The reinforcing ribs are provided below the maintaining member, the reinforcing ribs extend radially along the kettle body, and a plurality of the reinforcing ribs are uniformly distributed circumferentially along the outer ring wall within the gap formed between the outer ring wall and the inner ring wall.

[0014] On the outer side wall of the clamping wall, there are an upper anti - detachment convex part and a lower anti - detachment convex part that respectively extend circumferentially and protrude outward. The upper anti - detachment convex part and the lower anti - detachment convex part are in contact with the kettle body, and the upper anti - detachment convex part and the lower anti - detachment convex part are connected by an inner concave wall through a transition connection.

[0015] The kettle body is provided with a limiting convex part, the limiting convex part abuts against the inner concave wall and abuts against the bottom of the upper anti - detachment convex part; along the radial direction of the kettle body, the maintaining member is disposed opposite to the inner side of the upper anti - detachment convex part.

[0016] The outer wall surface of the inner concave wall gradually inclines towards the kettle body from top to bottom; alternatively, the outer wall surface of the inner concave wall includes a plurality of steps that gradually protrude outward from top to bottom.

[0017] The maintaining member is configured as a metal ring.

[0018] Due to the adoption of the above - mentioned technical solution, the technical effects achieved by this application at least include:

[0019] 1. According to the analysis, it is found that the main reason for the easy detachment of the plastic base in the prior art even without being knocked is that the plastic base has a weak anti - deformation ability. After the plastic base is deformed, the bonding force with the kettle body will become weak, resulting in the easy detachment of the plastic base. For example, during production or transportation, the plastic base is extruded and deformed under the influence of stress, resulting in the plastic base not being closely attached to the kettle body, so that the bonding force between the plastic base and the kettle body has been affected even before the kettle is used; another example is that under the influence of temperature, the plastic base deforms itself due to thermal expansion and contraction, and because the thermal expansion coefficients of the kettle body and the plastic base are different, the bonding force between the plastic base and the kettle body will become weak and cause detachment.

[0020] For the kettle provided by the present application, the clamping wall of the base fits the kettle body along the radial direction of the kettle body, so that the base and the kettle body are relatively fixed. On the basis of this structure, by connecting a maintaining member with greater stiffness to the clamping wall and making the maintaining member abut against the clamping wall along the radial direction of the kettle body, the clamping wall is maintained in a state of fitting the kettle body, preventing the clamping wall from deforming. And by making the clamping wall fit the kettle body stably, through the frictional force or abutting force between the two, there is sufficient bonding force between the clamping wall and the kettle body. Especially for the solution where the base is a plastic part, the stiffness of the maintaining member is greater than that of the plastic base, and the maintaining member is less affected by temperature changes, which can effectively prevent the plastic base from deforming under the influence of external forces or temperature changes, so that the plastic base can be stably and reliably in a relatively fixed state with the kettle body, thus effectively solving the problem that the base is prone to falling off.

[0021] 2. As a preferred embodiment of the present application, the clamping wall includes an outer ring wall and an inner ring wall. The maintaining member is between the outer ring wall and the inner ring wall and abuts against the inner surface of the outer ring wall and the outer surface of the inner ring wall. The outer ring wall located on the outside maintains a fitting state with the kettle body, and the inner ring wall located on the inside can play a role in strengthening the structure of the entire base. The inner ring wall and the maintaining member can together limit the inward contraction and deformation of the outer ring wall. In addition, the central position of the base is the main heat receiving area when the kettle body contains high-temperature liquids or ingredients. Therefore, compared with the outer ring wall located on the periphery, the inner ring wall closer to the center receives greater heat transfer and is thus more likely to increase in temperature and expand outward. When the distance of the outward expansion of the inner ring wall is within a reasonable range, it can better limit the inward contraction of the outer ring wall, but it is also necessary to prevent the inner ring wall from expanding excessively and causing the outer ring wall to squeeze the kettle body and deform outward. Therefore, the maintaining member is between the outer ring wall and the inner ring wall and abuts against the inner surface of the outer ring wall and the outer surface of the inner ring wall. On the one hand, it limits the inward contraction and deformation of the outer ring wall, ensures that the outer ring wall is in a stable fitting state with the kettle body, and improves the anti-falling-off effect of the base. On the other hand, it can also limit the excessive outward expansion and deformation of the inner ring wall to reduce the risk of the base squeezing the kettle body and deforming outward.

[0022] 3. As a preferred embodiment of the present application, the gap formed between the outer ring wall and the inner ring wall is configured as a gradually decreasing gradient structure from top to bottom, so that the maintaining member can be installed between the outer ring wall and the inner ring wall from top to bottom. And the lower the installation position of the maintaining member, the greater the outward squeezing force on the outer ring wall and the inward squeezing force on the inner ring wall, so that the effect of restricting the inward contraction of the outer ring wall and restricting the outward expansion of the inner ring wall is better, the structure of the base is more stable, and the anti-falling-off effect is better.

[0023] 4. As a preferred embodiment of the present application, a reinforcing structure is connected to the inner side of the outer ring wall. The reinforcing structure is arranged circumferentially along the outer ring wall to enhance the structural strength of the outer ring wall, further reducing the risk of inward shrinkage deformation of the outer ring wall and improving the anti-detachment effect. In a preferred embodiment, the reinforcing structure includes reinforcing ribs connected between the inner ring wall and the outer ring wall, which can not only limit the inward shrinkage of the outer ring wall but also limit the outward expansion of the inner ring wall, further enhancing the structural stability of the base.

[0024] 5. As a preferred embodiment of the present application, the outer side wall of the clamping wall is provided with an upper anti-detachment convex portion and a lower anti-detachment convex portion that extend circumferentially and protrude outward. The upper anti-detachment convex portion and the lower anti-detachment convex portion are connected by an inner concave wall in a transitional manner, making the upper and lower ends of the overall outer ring wall protrude outward and the middle part concave inward. During the process of strongly pressing the base into the bottom of the kettle body, the upper anti-detachment convex portion and the lower anti-detachment convex portion slightly contract inward under the extrusion of the kettle body. When the base is completely pressed in, the upper anti-detachment convex portion and the lower anti-detachment convex portion recover outward and generate a relatively large abutting pressure with the kettle body, thereby enhancing the fitting strength between the clamping wall and the kettle body.

[0025] 6. As a preferred embodiment of the present application, the kettle body is provided with a limiting convex portion. The limiting convex portion abuts against the inner concave wall and abuts against the bottom of the upper anti-detachment convex portion. The frictional force generated by the limiting convex portion on the inner concave wall and the upward supporting force on the upper anti-detachment convex portion limit the base when there is a tendency to fall downward, effectively preventing the base from falling off the kettle body. Since the base needs to deform the upper anti-detachment convex portion inward to cross the limiting convex portion when falling downward, the risk of the base falling off is further reduced by the restricting effect of the maintaining member being directly opposite to the inner side of the upper anti-detachment convex portion to limit the inward deformation of the upper anti-detachment convex portion.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0042] In an embodiment of this application, a kettle is provided. For the convenience of description and understanding, the following content provided by this application is all elaborated based on the structure of the illustrated product. Of course, those skilled in the art can understand that the above structure is only a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided by this application.

[0043] As Figures 1 to 6 shown, a kettle provided by this application includes a kettle body 1 and a base 2; wherein, the base 2 includes a clamping wall 21, and the clamping wall 21 abuts and fits against the kettle body 1 along the radial direction of the kettle body 1, so that the base 2 and the kettle body 1 are relatively fixed; the clamping wall 21 is connected with a maintaining member 3, the rigidity of the maintaining member 3 is greater than that of the clamping wall 21, and the maintaining member 3 abuts against the clamping wall 21 along the radial direction of the kettle body 1, so that the clamping wall 21 is maintained in a state of fitting against the kettle body 1. In a preferred embodiment, the base 2 can be made of a plastic part to improve the wear resistance of the kettle and improve the drop protection effect by using the plasticity of the plastic part. In another preferred embodiment, to make the base 2 support the kettle body 1 reliably and stably, the base 2 can further include a bottom wall 22, and the clamping wall 21 is connected above the bottom wall 22 and extends around the circumference of the bottom wall 22.

[0044] For the kettle of this application, the clamping wall 21 of the base 2 fits against the kettle body 1 along the radial direction of the kettle body 1, making the base 2 and the kettle body 1 relatively fixed. On the basis of this structure, by connecting the clamping wall 21 with a maintaining member 3 having a greater rigidity and making the maintaining member 3 abut against the clamping wall 21 along the radial direction of the kettle body 1, the clamping wall 21 is maintained in a state of fitting against the kettle body 1, preventing the clamping wall 21 from deforming. Especially for the embodiment in which the base 2 is a plastic part as described above, the rigidity of the maintaining member 3 is greater than that of the plastic base 2, and the shape change of the maintaining member 3 caused by temperature or external force is smaller, which can effectively inhibit the deformation of the plastic base 2 under the action of temperature or external force, and further enable the plastic base 2 to be stably and reliably in a relatively fixed state with the kettle body 1, thus effectively solving the problem that the base 2 is easily detached.

[0045] Regarding the structure of the maintaining member 3, in a preferred embodiment, as Figure 2 andFigure 3 As shown, the maintaining member 3 is configured as a metal ring, such as a steel ring, an aluminum alloy ring, a copper ring, etc. Figure 2 In the cross-sectional view shown in, a structural embodiment in which the maintaining member 3 has a circular cross-section is schematically illustrated. In other embodiments, the cross-section of the maintaining member 3 may also be rectangular, elliptical, rhombic, etc.

[0046] Regarding the structure of the clamping wall 21, as a preferred embodiment, as Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, the clamping wall 21 includes an outer ring wall 211 and an inner ring wall 212 connected to the inner side of the outer ring wall 211. The maintaining member 3 is disposed in a gap formed between the outer ring wall 211 and the inner ring wall 212; along the radial direction of the kettle body 1, the maintaining member 3 abuts against the inner surface of the outer ring wall 211 and the outer surface of the inner ring wall 212. Those skilled in the art can understand that the outer ring wall 211 located on the outside maintains a fitting state with the kettle body 1, and the inner ring wall 212 located on the inside can play a role in strengthening the structure of the entire base 2. The inner ring wall 212 and the maintaining member 3 can together limit the inward shrinkage deformation of the outer ring wall 211. In addition, the central position of the base 2 is the main heat-receiving area when the kettle body 1 contains high-temperature liquids or ingredients. Therefore, compared with the outer ring wall 211 located on the periphery, the inner ring wall 212 near the center is prone to expand outward due to temperature rise. When the distance of the outward expansion of the inner ring wall 212 is within a reasonable range, it can better limit the inward shrinkage of the outer ring wall 211, but it is also necessary to prevent the inner ring wall 212 from expanding excessively and causing the outer ring wall 211 to squeeze the kettle body 1 outward and deform. Therefore, the maintaining member 3 is between the outer ring wall 211 and the inner ring wall 212 and abuts against the inner surface of the outer ring wall 211 and the outer surface of the inner ring wall 212. On the one hand, it limits the inward shrinkage deformation of the outer ring wall 211, ensures that the outer ring wall 211 is in a stable fitting state with the kettle body 1, and improves the anti-detachment effect of the base 2. On the other hand, it can also limit the excessive outward expansion deformation of the inner ring wall 212 to reduce the risk of the base 2 squeezing the kettle body 1 outward and deforming.

[0047] As a preferred embodiment under this embodiment, the gap formed between the outer ring wall 211 and the inner ring wall 212 is configured as a gradually narrowing structure from top to bottom. Specifically, the width of the gap formed between the outer ring wall 211 and the inner ring wall 212 can be gradually narrowed from top to bottom. The maintaining member 3 can be installed between the outer ring wall 211 and the inner ring wall 212 from top to bottom, and the lower the installation position of the maintaining member 3, the greater the outward squeezing force on the outer ring wall 211 and the inward squeezing force on the inner ring wall 212, so that the effect of restricting the inward shrinkage of the outer ring wall 211 and restricting the outward expansion of the inner ring wall 212 is better, the structure of the base 2 is more stable, and the anti-detachment effect is better.

[0048] As a preferred embodiment of this embodiment, a reinforcing structure is connected to the inner side of the outer ring wall 211, and the reinforcing structure is arranged along the circumferential direction of the outer ring wall 211. The presence of the reinforcing structure strengthens the structural strength of the outer ring wall 211, further reduces the risk of the inner contraction deformation of the outer ring wall 211, and improves the anti-detachment effect.

[0049] In a specific embodiment, the reinforcing structure may be only connected to the outer ring wall 211 and arranged at an interval from the inner ring wall 212. As a more preferred embodiment, as Figure 4 and Figure 6 shown, the reinforcing structure includes a reinforcing rib 213 connected between the inner ring wall 212 and the outer ring wall 211. Those skilled in the art can understand that the reinforcing rib 213 connects the inner ring wall 212 and the outer ring wall 211 together, which can not only limit the inward contraction of the outer ring wall 211, but also limit the outward expansion of the inner ring wall 212, further improving the structural stability of the base 2.

[0050] Furthermore, as Figure 2 and Figure 6 shown, the reinforcing rib 213 is arranged below the maintaining member 3, the reinforcing rib 213 extends along the radial direction of the kettle body 1, and a plurality of the reinforcing ribs 213 are uniformly distributed in the gap formed between the outer ring wall 211 and the inner ring wall 212 along the circumferential direction of the outer ring wall 211, so that the inner ring wall 212 and the outer ring wall 211 form multi-point connections in the circumferential direction, and through the uniformity of the distribution of the reinforcing ribs 213, the acting forces generated between the inner ring wall 212 and the outer ring wall 211 are uniformly distributed in the circumferential direction of the base 2, which helps to improve the structural stability of the base 2 and reduce the deformation risk. The reinforcing rib 213 is arranged below the maintaining member 3, which can form a limit on the maintaining member 3 in the vertical direction and limit the lowest position of the maintaining member 3 to ensure that the position of the maintaining member 3 achieves the best effect of restricting the outward expansion of the inner ring wall 212 and restricting the inward contraction of the outer ring wall 211.

[0051] As a preferred embodiment of the present application, as Figure 2 and Figure 6As shown, on the outer wall of the clamping wall 21, there are an upper anti - detachment convex part 2111 and a lower anti - detachment convex part 2112 that extend circumferentially and protrude outward respectively. The upper anti - detachment convex part 2111 and the lower anti - detachment convex part 2112 are in contact with the kettle body 1, and the upper anti - detachment convex part 2111 and the lower anti - detachment convex part 2112 are connected by an inner concave wall 2113 in a transitional manner. Through this design, the upper and lower ends of the overall outer ring wall 211 protrude outward, and the middle is concave. To a certain extent, the flexibility of the upper and lower ends of the outer ring wall 211 is increased, and it is not easy to break when being strongly pressed into the bottom of the kettle body 1. During the process of strongly pressing the base 2 into the bottom of the kettle body 1, the upper anti - detachment convex part 2111 and the lower anti - detachment convex part 2112 slightly contract inward under the extrusion of the kettle body 1. When the base 2 is completely pressed in, the upper anti - detachment convex part 2111 and the lower anti - detachment convex part 2112 recover outward and generate a relatively large abutting pressure with the kettle body 1, thereby enhancing the fitting strength between the clamping wall 21 and the kettle body 1.

[0052] Further, as Figure 2 and Figure 6 shown, the kettle body 1 is provided with a limiting convex part 11. The limiting convex part 11 abuts against the inner concave wall 2113 and abuts against the bottom of the upper anti - detachment convex part 2111; along the radial direction of the kettle body 1, the maintaining member 3 is disposed opposite to the inner side of the upper anti - detachment convex part 2111. The limiting convex part 11 abuts against the inner concave wall 2113 and can generate frictional force on the inner concave wall 2113. The limiting convex part 11 abuts against the bottom of the upper anti - detachment convex part 2111 and generates an upward supporting force on the upper anti - detachment convex part 2111. The generation of frictional force and supporting force makes it possible to prevent the base 2 from falling off the kettle body 1 when the base 2 shows a tendency to fall downward due to the abutting action of the limiting convex part 11. Since the base 2 needs to deform the upper anti - detachment convex part 2111 inward to cross the limiting convex part 11 when falling downward, therefore, by disposing the maintaining member 3 opposite to the inner side of the upper anti - detachment convex part 2111 to form a function of restricting the inward deformation of the upper anti - detachment convex part 2111, the risk of the base 2 falling off is further reduced.

[0053] In a preferred embodiment, the outer wall surface of the inner concave wall 2113 includes a plurality of steps that gradually protrude outward from top to bottom, as Figure 2 and Figure 6As shown, the concave wall 2113 is schematically shown to be composed of two upper and lower steps. During assembly, the limiting convex portion 11 can be abutted against the upper step, so that the limiting convex portion 11 can enter the concave wall 2113 deeper, thereby effectively abutting against the upper anti-disengagement convex portion 2111. The position where the lower step is located increases the thickness of the outer ring wall 211 relative to the position where the upper step is located, which helps to improve the strength of the outer ring wall 211. Moreover, it can also abut against the bottom of the limiting convex portion 11 in the vertical direction and be limited by the limiting convex portion 11 to prevent the base 2 from deforming upward. In another preferred embodiment, different from the embodiment in which the concave wall 2113 includes a plurality of steps described above, the outer wall surface of the concave wall can also be gradually inclined toward the kettle body 1 from top to bottom. During assembly, the limiting convex portion 11 can be abutted against the upper part of the concave wall, and then it can enter the concave wall deeper and effectively abut against the upper anti-disengagement convex portion 2111. The lower the concave wall is, the greater its thickness is, which helps to improve the strength of the outer ring wall 211. Moreover, it can also prevent the base 2 from deforming upward in the vertical direction.
