Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to a kettle base. Background Technology

[0002] Existing kettles connect to their base via couplers, enabling automatic water filling and electric heating. As shown in Chinese patent CN205410859U, the coupler includes an upper coupler and a lower coupler. The upper coupler is located at the bottom of the kettle, and the lower coupler is located on the kettle base. The kettle is connected by inserting the upper and lower couplers together. However, the outer contours of current couplers are all straight, resembling cylinders, making the connection between the upper and lower couplers inconvenient. The kettle needs to be placed precisely to complete the connection, thus improving usability. Utility Model Content

[0003] In view of this, the present invention proposes a kettle base, which aims to improve the convenience of connecting with a kettle.

[0004] The solution provided by this utility model includes:

[0005] A kettle base includes a base body and a lower coupler disposed on the base body. The outer contour of the lower coupler forms a first conical guide surface and a second conical guide surface from bottom to top. The first conical guide surface forms a first angle with a horizontal plane, and the second conical guide surface forms a second angle with a horizontal plane. The second angle is greater than the first angle.

[0006] As a further optional solution, a transition fillet is formed at the junction of the first tapered guide surface and the second tapered guide surface.

[0007] As a further optional option, the height ratio of the first conical guide surface to the height of the second conical guide surface is 0.9:1 to 1:0.9.

[0008] As a further alternative, the first included angle is 40-50°.

[0009] As a further alternative, the first included angle is 45°.

[0010] As a further alternative, the second included angle is 75-85°.

[0011] As a further alternative, the second included angle is 85°.

[0012] Compared with the prior art, the kettle base of this application has at least the following advantages:

[0013] The lower coupler on the kettle base features a two-stage guide structure, comprising a first conical guide surface and a second conical guide surface. The first conical guide surface has a gentler angle, while the second conical guide surface is closer to a vertical plane. The first conical guide surface acts as a wide docking guide surface, increasing the contact area between the kettle bottom and the first conical guide surface when the user presses the kettle down. This results in a significant lateral displacement compensation effect, allowing the kettle to automatically slide into the correct position even if it is significantly off-center. Furthermore, the near-vertical second conical guide surface provides precise axial positioning during the final docking stage. This design, employing coarse positioning followed by fine positioning, enables rapid guidance and ensures accurate positioning between the kettle and its base, simplifying the docking process and improving ease of use.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] refer to Figure 1 and Figure 2 This utility model discloses a kettle base, including a base body 1 and a lower coupler 2 disposed on the base body 1. The outer contour of the lower coupler 2 forms a first conical guide surface 21 and a second conical guide surface 22 from bottom to top. The first conical guide surface 21 forms a first angle K1 with the horizontal plane, and the second conical guide surface 22 forms a second angle K2 with the horizontal plane. The second angle K2 is greater than the first angle K1. The first conical guide surface 21 has a gentler inclination, while the second conical guide surface 22 is closer to the vertical plane.

[0024] The lower coupler 2 on the kettle base features a two-stage guide structure, comprising a first conical guide surface 21 and a second conical guide surface 22. The first conical guide surface 21 has a gentler angle, while the second conical guide surface 22 is closer to a vertical plane. The first conical guide surface 21 serves as a wide docking guide surface, increasing the contact area between the kettle bottom and the first conical guide surface 21 when the user presses the kettle down, resulting in a significant lateral displacement compensation effect. Even if the kettle is placed significantly off-center, it can be guided automatically into the correct position via the first conical guide surface 21. Furthermore, the nearly vertical second conical guide surface 22 provides precise axial positioning during the final docking stage. Thus, this design, employing coarse positioning followed by fine positioning, enables rapid guidance and ensures precise positioning between the kettle and its base.

[0025] It should be noted that the outer contour of the upper coupler of the kettle, which mates with the kettle base, should match that of the lower coupler 2. This embodiment only involves improving the shape of the outer contour surface of the coupler, and does not involve improvements to the internal structure or working principle; therefore, it will not be elaborated upon. For the connection principle of the coupler, please refer to the prior art CN205410859U.

[0026] This embodiment forms a gradually transitioning guide structure from bottom to top by providing a first tapered guide surface 21 and a second tapered guide surface 22 on the outer contour of the lower coupler 2. The first tapered guide surface 21 provides a wide mating guide surface, allowing the kettle to be gradually aligned with the lower coupler 2 even with some deviation during insertion, guided by the slope. The second tapered guide surface 22 provides precise axial positioning during the final mating stage, ensuring the kettle can be securely connected to the base. This design solves the problem of inconvenient mating of the upper and lower couplers in the prior art, improving the convenience and accuracy of mating the kettle with the base.

[0027] In some embodiments, such as Figure 2 As shown, a transition fillet 23 is formed at the junction of the first tapered guide surface 21 and the second tapered guide surface 22.

[0028] The transition fillet 23 is formed at the junction of the first conical guide surface 21 and the second conical guide surface 22, making the docking process smoother and reducing jamming. The transition fillet 23 can reduce stress concentration at the junction of the first conical guide surface 21 and the second conical guide surface 22, reduce friction and wear, and thus extend the insertion and extraction life.

[0029] The transition fillet 23 can be formed in various ways, such as through precise machining to create a smooth transition area, or directly through mold forming during the manufacturing process. Furthermore, the radius of the transition fillet 23 can be adjusted according to specific requirements to achieve optimal guiding effect and durability.

[0030] In some embodiments, such as Figure 2 As shown, the height ratio of the first conical guide surface 21 to the height of the second conical guide surface 22 is 0.9:1 to 1:0.9.

[0031] Among them, the overall guiding efficiency is highest when the height ratio is 1:1, balancing coarse positioning speed and fine positioning accuracy; then, based on manufacturing errors, the height ratio can be extended to 0.9:1 to 1:0.9. By adjusting the height ratio of the first conical guide surface 21 to the second conical guide surface 22, the guiding effect can be optimized within a certain range, ensuring smoother docking of the upper and lower couplers.

[0032] In some embodiments, the first included angle K1 is set within the range of 40-50°. This angle range design makes it easier for the upper and lower couplers to align and connect during docking, thereby improving the convenience and success rate of docking. As a preferred embodiment, the first included angle K1 can be set to 45° to further optimize the convenience of docking.

[0033] In some embodiments, the second included angle K2 is set in the range of 75-85°. This angle range design can meet the requirements for precise positioning and allow for a smooth transition of the insertion and extraction force curve. As a preferred embodiment, the first included angle K1 can be set to 85°.

[0034] In summary, this application provides a kettle base with a lower coupler 2 featuring a two-stage guide structure, comprising a first conical guide surface 21 and a second conical guide surface 22. The first conical guide surface 21 has a gentler included angle, while the second conical guide surface 22 is closer to a vertical plane. The first conical guide surface 21 serves as a wide docking guide surface, resulting in a larger contact area between the kettle bottom and the first conical guide surface 21 when the user presses down on the kettle. This creates a significant lateral displacement compensation effect, allowing the kettle to automatically slide into the correct position even if it deviates significantly from the centerline. Furthermore, the nearly vertical second conical guide surface 22 provides precise axial positioning during the final docking stage. Thus, this design, employing coarse positioning followed by fine positioning, enables rapid guidance and ensures precise positioning between the kettle and the kettle base, simplifying the docking process and improving ease of use.

[0035] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
