Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to an assembled spout connection structure. Background Technology

[0002] Most kettles on the market today use a single-piece welding process for the spout and body. While this process ensures the strength of the connection between the spout and body, it also introduces some significant drawbacks.

[0003] First, the manufacturing process for single-unit welding is relatively complex, requiring higher precision molds and more complicated processes. This directly leads to increased manufacturing costs, which are ultimately reflected in product prices and increase the economic burden on consumers.

[0004] Secondly, because the spout and body of a single-piece welded kettle cannot be disassembled, the overall size is large, which occupies a lot of space during storage and transportation, increasing logistics costs and reducing transportation efficiency.

[0005] Furthermore, the use of single-piece welding in the market also limits the flexibility of product design. For example, it is difficult to match spouts and bodies of different materials or colors, which is not conducive to product diversification and personalization and cannot meet the growing aesthetic needs of consumers. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a low-cost, easy-to-assemble assembled spout connection structure.

[0007] This utility model is achieved through the following technical solution:

[0008] To solve the above-mentioned technical problems, this utility model provides an assembled spout connection structure, including a pot body and a spout. The pot body is provided with an insertion hole for the lower end of the spout to be inserted. The lower end of the spout is fitted with a sealing ring located inside the insertion hole, and a pressure cap for pressing the sealing ring simultaneously onto the inner wall of the pot body and the outer wall of the spout. A snap-fit ​​structure is provided between the pressure cap and the lower end of the spout, and the pressure cap is fixedly connected to the inner wall of the pot body.

[0009] To further solve the technical problem to be solved by this utility model, this utility model provides an assembled spout connection structure in which the snap-fit ​​structure includes an elastic snap tongue provided on the pressure cap and a snap groove provided on the outer side wall of the lower end of the spout, and the snap tongue can snap and cooperate with the corresponding snap groove.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] like Figures 1 to 3 As shown, this utility model provides a specific embodiment of an assembled spout connection structure. In this embodiment, the kettle body 1 is provided with a circular insertion hole 11 for the lower end of the spout 2 to be inserted. The lower end of the spout 2 is fitted with a sealing ring 3 located inside the insertion hole 11, and the inner side of the sealing ring 3 is provided with a pressure cap 4 that simultaneously presses it against the inner wall of the kettle body 1 and the outer wall of the spout 2, forming a reliable sealing connection.

[0030] Preferably, the pressure cap 4 is fixedly connected to the inner wall of the pot body 1 by processes such as spot welding, while the sealing ring 3 is stuck inside the pressure cap 4.

[0031] To securely fix the spout 2 to the kettle body 1, this embodiment employs a snap-fit ​​structure. Specifically, multiple (e.g., two or more) elastic latches 41 are evenly distributed on the side wall of the pressure cap 4. Corresponding to the latches 41, multiple (e.g., two or more) slots 21 are also evenly distributed on the outer side wall of the lower end of the spout 2. When the spout 2 is inserted into the kettle body 1, the latches 41 of the pressure cap 4 elastically snap into the slots 21, thereby achieving a quick connection and fixation between the spout 2 and the kettle body 1.

[0032] The spout 2 and body 1 of this invention are independent of each other and can be designed, manufactured, and transported separately, greatly improving production efficiency and flexibility. This modular design concept reduces production costs and simplifies inventory management. During transportation, the spout 2 and body 1 can be packaged separately, reducing volume and weight, thereby lowering transportation costs and effectively avoiding damage caused by collisions or compression during transportation.

[0033] At the factory, the sealing ring 3 is installed in the pressure cap 4, and then the pressure cap 4 is welded to the inner wall of the pot body 1 inside the insertion hole 11 by a spot welding process.

[0034] Once delivered to the end user, the spout 2 and the kettle body 1 can be quickly and easily assembled. The user simply inserts the spout 2 into the insertion hole 11 of the kettle body 1 until the latch 41 engages with the slot 21 to complete the assembly. This convenient assembly method requires no tools or professional skills and can be easily operated even by ordinary users.

[0035] The design of the sealing ring 3 and the pressure cap 4 ensures the sealing performance at the connection between the spout 2 and the body 1, effectively preventing liquid leakage. The sealing ring 3 is made of elastic material, allowing it to fit tightly against the contact surfaces of the spout 2 and the body 1, forming a reliable sealing barrier. The pressure cap 4 is welded (e.g., spot-welded) to the inner wall of the body 1, applying pressure to press the sealing ring 3 firmly against the inner wall of the body 1. When the spout 2 is inserted, the interference fit between the spout 2 and the sealing ring further enhances the sealing effect. The snap-fit ​​structure allows for quick fixation of the spout 2, simplifying the assembly process and ensuring a stable connection.

[0036] In summary, this utility model, through modular design, convenient assembly method, reliable sealing structure and stable snap-fit ​​structure, achieves low-cost and high-efficiency production and assembly, and provides users with a more convenient and safer user experience.

[0037] To facilitate pouring out the liquid and prevent residue, the lower end of the spout 2 is provided with a first pouring notch 22, and the cap 4 is provided with a second pouring notch 42 aligned with the first pouring notch 22. These two pouring notches are preferably arranged in the vertical direction to ensure that the liquid can flow out smoothly.

[0038] In addition, to prevent the spout 2 from rotating on the body 1, a circumferential limiting structure can be provided between the cap 4 and the spout 2. For example, several circumferentially distributed grooves can be provided on the outer wall of the spout 2, which cooperate with the corresponding protrusions on the inner wall of the cap 4 to form a shape fit, thereby restricting the rotation of the spout 2.

[0039] To further enhance the sealing performance, the edge of the insertion hole 11 is preferably provided with an inner folded edge 111 extending into the body 1. A protrusion 31 is provided on the inner sidewall of the sealing ring 3. The diameter of the protrusion 31 is larger than the diameter of the inner folded edge 111, so that the protrusion 31 can extend between the inner folded edge 111 and the outer wall of the spout 2, further enhancing the sealing and stability.

[0040] The pressure cap 4 is provided with an annular top pressure plate 43 for welding to the inner wall of the pot body 1, and an annular top pressure step 44 for pressing the two adjacent sides of the sealing ring 3, so that the sealing ring 3 is subjected to uniform pressure and ensures the sealing effect.

[0041] Example 2:

[0042] like Figures 4 to 6 As shown, the main difference between another embodiment of this utility model and embodiment one lies in the structure of the pressure cap 4 and the snap-fit ​​method.

[0043] In this embodiment, the cap 4 includes an inner cap 4a and an outer cap 4b that are fitted together. The inner cap 4a presses directly onto the sealing ring 3, while the outer cap 4b presses onto the inner cap 4a. An elastic latch 41 is provided on the inner cap 4a, and a second drain notch 42 is provided on the outer cap 4b.

[0044] Unlike the multiple independent structures of the slot 21 in Embodiment 1, in this embodiment, the slot 21 is a continuous groove arranged around the outer wall of the spout 2. Multiple latches 41 on the inner cover 4a can be inserted into this groove to connect and fix the spout 2 and the kettle body 1. This structure facilitates alignment and makes assembly easier.

[0045] Preferably, the inner cover 4a and the outer cover 4b are provided with adjustment notches to facilitate alignment or to achieve circumferential fine adjustment.
