Description

Technical Field

[0001] The utility model relates to a cup holder mechanism of a coffee machine, in particular to a cup holder mechanism fixed by a deformed clip spring of the coffee machine. Background Art

[0002] A coffee machine is an electrical device used for making coffee, generally classified as semi-automatic or fully automatic. Semi-automatic coffee machines rely on manual operation for grinding, compacting, filling, brewing, and removing residue. A fully automatic coffee machine is a coffee machine that fully automates the entire coffee brewing process, including preheating, cleaning, grinding, compacting, brewing, and draining. It brews coffee according to scientific data and procedures, and delivers coffee with just a click. To facilitate the placement and use of coffee cups, some coffee machines have a cup holder mechanism on the side of the machine body below the water outlet, such as the application number 202321830836.5 disclosed in the Chinese patent literature, with the authorization announcement date of December 26, 2023, and the utility model name "A cup support structure and a coffee machine having the same." However, the cup holder mechanism design of these existing coffee machines has some shortcomings. Primarily, the traditional cup holder is typically fixed to the coffee machine, which cannot accommodate usage requirements at different angles, limiting user convenience. Furthermore, existing cup holder mechanisms are often not secure enough, which can easily cause the cup holder to loosen or wobble, affecting the user experience. Furthermore, existing cup holder mechanisms struggle to meet requirements for cup placement at specific angles. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the present invention aims to provide a coffee machine cup holder mechanism using a deformable retaining spring. This mechanism addresses the technical issues of existing cup holder mechanisms in similar coffee machines, such as poor design, limited load-bearing capacity, susceptibility to loosening and shaking, and difficulty in using the cup holder at specific angles. This objective is achieved through the following technical solution.

[0004] The cup holder mechanism of the coffee machine is fixed with a deforming retaining spring. The cup holder mechanism comprises: a main body, a rotating shaft bracket and a tray, the main body being fixedly arranged on the body of the coffee machine, the rotating shaft bracket being fixedly provided with a rotating shaft bracket in a groove on one side of the main body, the bottom of the rotating shaft bracket being provided with an opening, two ends of the rotating shaft bracket being raised and extending out of the hinge seat of the main body, and a tray being hinged and fixed to the hinge seat on one side, and two ends of the tray at the hinge seat being respectively provided with an inserted rotating shaft column; the key point of its structural design is that a deforming retaining spring is provided in one of the hinge seats of the rotating shaft bracket, which is inserted into and fixed in the hinge seat through the bottom opening of the rotating shaft bracket, and the rotating shaft column of the tray is interference-fastened with the bottom inner side of the opening of the deforming retaining spring; limit plates integrally formed with the tray are respectively provided under the rotating shaft columns of the tray, and after the tray is rotated and opened 90 degrees, the limit plates of the tray respectively abut and fit in the plate edge grooves at the bottom of the hinge seat, and the tray is fixed in a horizontal direction. The aforementioned deformable retaining spring is not limited to the pivot column on one side of the pallet; deformable retaining springs can also be installed in the hinged seats of the pivot columns on both sides of the pallet. Furthermore, to achieve vertical fixation of the pallet, the pallet is designed with a specific structure that cooperates with the deformable retaining spring. The pivot column of the pallet adopts a slot-like form that tightly cooperates with the deformable retaining spring, ensuring vertical stability of the pallet. Furthermore, to ensure excellent precision and stability, the corresponding shape between the pivot column and the deformable retaining spring ensures that the pallet will not tilt or wobble during use.

[0005] The oblique end of the hinge seat at the shaft bracket in the rotation direction of the pallet is provided with an end opening, and the outer diameter end of the inner bottom of the opening of the deformation retaining spring extends out of the end opening of the hinge seat; the top notch of the shaft edge groove at the limiting plate below the rotating shaft column of the pallet is provided with a notch edge protruding toward the hinge seat, and the rotating shaft column is higher than the notch edge; the shape of the end of the deformation retaining spring extending out of the hinge seat corresponds to the internal shape of the rotating shaft column after the pallet is retracted and rotated 90°, and the groove between the limiting plate of the pallet and the notch edge is fixed to the end of the deformation retaining spring extending out of the hinge seat by interference fit, and the pallet is fixed in the vertical direction.

[0006] The inner rotating shaft bracket of the deformable retaining spring at the hinge seat is provided with a fastening screw. In the above structure, since the torsional force of the deformable retaining spring is large, the fastening screw is used to further fix the rotating shaft bracket and the main body, thereby improving its service life and stability.

[0007] The deformable retaining spring is inserted through the opening at the end of the hinge seat of the rotating shaft bracket and fixed in the hinge seat. After the deformable retaining spring is inserted, it is fixed in the hinge seat after being deformed and restored, or it can be further fixed in the hinge seat by screws or clamping plates, thereby facilitating the assembly of the deformable retaining spring.

[0008] The main body and the rotating shaft bracket are integrally formed and arranged on the body of the coffee machine.

[0009] The tray's surface is symmetrically provided with strip-shaped drain holes on either side. A large, horizontally positioned waist-shaped hole is positioned between the parallel strip-shaped drain holes. Two symmetrically positioned small waist-shaped holes are positioned on either side of the large waist-shaped hole. This structure allows for the placement of coffee cups and draining, while also facilitating the placement of utensils such as spoons and cup lids. For example, the spoon handle can be inserted into the small waist-shaped hole, with the spoon head restrained within it. The vertical portion of the cup lid can be inserted into the long waist-shaped hole.

[0010] The utility model has a reasonable structural design, is easy to use, disassemble and maintain, improves the convenience and comfort of use, has good stability and safety, and has a wide range of applications. In particular, it has a large heavy-load force and good stability when vertically retracted, providing a better user experience; it is suitable for use as a deformable retaining spring fixing cup holder mechanism for coffee machines, as well as a structural improvement of similar products.

[0018] Now, in conjunction with the accompanying drawings, the structure and use of the utility model are further described. Figures 1-6As shown, this cup holder mechanism is a 90° rotating cup holder for coffee machines and is secured vertically using a deformable retaining spring 4, enhancing its flexibility and stability. Four screws secure the pivot bracket 2 to the tray 3. A pivot structure connects the tray and pivot bracket, enabling 90° rotation. When placed horizontally, the tray engages the pivot bracket, securing it in a horizontal position to prevent it from tilting or dropping.

[0019] The specific structure of this cup holder mechanism is as follows: a main body 1 is fixedly mounted on the coffee machine body. A rotating shaft bracket is fixedly mounted in a groove on one side of the main body. The bottom of the rotating shaft bracket has an opening. The rotating shaft bracket has two ends that protrude from a hinge seat 201 of the main body. A tray is also mounted on one side, hingedly fixed to the hinge seat. The tray has two ends with rotating shaft posts 301 inserted into the hinge seat. A deformable retaining spring is installed in one of the hinge seats and inserted through the bottom opening of the hinge seat. The rotating shaft post 301 of the tray is interference-fitted with the bottom inner side of the opening of the deformable retaining spring. A stopper plate 302 is integrally formed with the tray below the rotating shaft post. When the tray is rotated 90 degrees, the stopper plates abut against the plate edge grooves at the bottom of the hinge seat, fixing the tray in a horizontal direction. The hinged seat at the pivot bracket in the direction of the tray's rotation is provided with an end opening at the angled end. The outer diameter end of the inner bottom of the opening of the deformable retaining spring extends out of the end opening of the hinged seat. The top notch of the axis groove at the stop plate below the tray's pivot column is provided with a notch edge 303 that protrudes toward the hinged seat, with the pivot column protruding above the notch edge. The shape of the end of the deformable retaining spring extending out of the hinged seat corresponds to the internal shape of the pivot column after the tray is retracted and rotated 90°. The groove between the tray's stop plate and the notch edge is interlocked and fixed to the end of the deformable retaining spring extending out of the hinged seat, thereby securing the tray in a vertical position. A fastening screw 5 is provided on the inner pivot bracket of the deformable retaining spring at one hinged seat. The tray's surface is symmetrically provided with strip-shaped drainage holes. A large, horizontally arranged waist-shaped hole is located between the parallel strip-shaped drainage holes on both sides. Two symmetrically arranged small waist-shaped holes are located on either side of the large waist-shaped hole.

[0020] The installation method of the cup holder mechanism is as follows: place the deformed retaining spring into the hinge seat of the pivot bracket in the direction of the arrow. The deformed retaining spring will be inserted into the hinge seat of the pivot bracket after deformation, and the pivot columns on both sides of the tray are respectively fitted into the hinge seats of the pivot bracket with interference fit, and the installation is completed; the shape of the deformed retaining spring corresponds to the internal shape of the pivot column after the tray is rotated 90°, and the tray is fixed in the vertical direction.

[0021] In summary, the cup holder mechanism includes: a tray, a rotating mechanism, a deformable clip fixing device, a vertical fixing structure, and a rotating mechanism.

[0022] The tray is made of high-strength, durable stainless steel to ensure that it can bear the weight of the cup; the shape and size of the tray should be designed according to the specifications of common coffee cups to provide good support and stability; at the same time, the surface has a hollow design to allow excess water and coffee liquid to automatically seep out of the tray.

[0023] The rotating mechanism is located at the connection between the tray and the coffee machine, realizing the tray's rotatable function; at the same time, the rotating mechanism adopts a rotating shaft structure to ensure that the tray rotates smoothly by 90°; and a limiting device is designed to limit the tray's rotation angle within the range of 90° to prevent excessive rotation from causing damage or affecting use.

[0024] The deformable circlip fixing device consists of a deformable circlip, which is used to fix the tray vertically on the coffee machine. The deformable circlip has good elasticity and strength, adapting to different installation sizes and tolerances, ensuring that the tray is firmly installed and not easy to loosen. At the same time, the installation method of the circlip is simple and convenient, and it is easy to install and remove. The material of the circlip has good corrosion resistance and wear resistance, ensuring long-term reliability.

[0025] In order to achieve vertical fixation of the pallet, the pallet is designed with a specific structure that cooperates with the deformable retaining spring; the vertical fixing structure adopts a slot form, which closely cooperates with the deformable retaining spring to ensure that the pallet remains stable in the vertical direction; the vertical fixing structure has good precision and stability, ensuring that the pallet will not tilt or shake during use.
