Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically a drawer-type funnel locking structure. Background Technology

[0002] In existing coffee machines, the method of fixing the drawer-type funnel is generally through the engagement of its own snap-fit ​​or protrusion with the recess in the main body. This method is the most cost-effective in terms of coffee machine production, but it is the worst in terms of user experience. The main reason is that the engagement between the funnel and the main body is limited or fixed entirely by the interference fit of the parts themselves. For example, if there is a recess in the funnel and a protrusion in the slot of the main body, when the funnel is inserted into the slot of the main body, the deformation of the plastic parts will limit or fix the recess and the protrusion to each other. However, after repeated use, the protrusion will be worn flat, which will cause the limiting or fixing between the recess and the protrusion to fail, resulting in the funnel being unable to be limited or fixed to the main body, with a short service life and a poor user experience.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The present invention aims to provide a drawer-type funnel locking structure to overcome the shortcomings of the prior art.

[0005] A drawer-type funnel locking structure designed for this purpose includes a main body and a funnel. The main body is provided with a slot, the funnel is provided with an insertion edge, the slot is provided with an elastic plunger, and the insertion edge is provided with a recess. The insertion edge is detachably inserted into the slot and elastically avoids or locks against the elastic plunger through the recess.

[0006] The slot is provided with a positioning hole. The elastic plunger includes an elastic element and a plunger. The elastic element is positioned on the positioning hole. The plunger elastically extends and retracts on the positioning hole through the elastic element, and avoids or locks with the concave hole during elastic extension and retraction.

[0007] The end of the plunger that elastically expands and contracts on the positioning hole is a raised semi-circle, and the recessed hole is a recessed semi-circle.

[0008] The elastic plunger also includes a bracket, which is detachably positioned on the positioning hole. The elastic element is positioned on the bracket, and the plunger elastically extends and retracts on the positioning hole and the bracket through the elastic element.

[0009] The elastic element is a compression spring, with one end acting elastically on the bracket and the other end acting elastically on the plunger.

[0010] The insertion edge extends horizontally along the top edge of the funnel.

[0011] The recessed hole is provided on the bottom or surface of the insertion edge.

[0012] The resilient plunger can be detachably mounted on the lower or upper side of the slot.

[0013] A filter screen is provided on the funnel.

[0014] The funnel is also provided with a handle on its outer side, and is detached from and attached to the main body via the handle.

[0015] Through the improvement of the above structure, this utility model provides an elastic plunger in the slot of the main body and a concave hole in the insertion edge of the funnel. By using the detachable insertion and assembly between the insertion edge and the slot, the funnel can be easily installed and removed from the main body.

[0016] When the funnel is assembled, the insert edge slides towards the slot and acts on the elastic plunger, so that the elastic plunger moves elastically and elastically avoids each other with the insert edge, so that the funnel can be assembled smoothly; when the funnel continues to slide towards the slot to a certain position, the elastic plunger separates from the insert edge and elastically resets, and locks in the concave hole to realize the assembly of the funnel.

[0017] By utilizing the elastic movement of the elastic plunger, it can elastically avoid and lock with the insertion edge and concave hole, thereby effectively ensuring the limiting and fixing between the funnel and the main body. This replaces the drawback of the interference fit between the funnel and the main body in the existing technology, thereby improving the product's stability, service life, and user experience.

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] See Figures 1-10 This drawer-type funnel locking structure includes a main body 1 and a funnel 2. The main body 1 is provided with a slot 3, the funnel 2 is provided with an insert edge 4, the slot 3 is provided with an elastic plunger, and the insert edge 4 is provided with a recessed hole 5. The insert edge 4 is detachably inserted into the slot 3, and elastically avoids or locks with the elastic plunger through the recessed hole 5.

[0031] In this embodiment, an elastic plunger is provided on the slot 3 of the main body 1, and a recessed hole 5 is provided on the insertion edge 4 of the funnel 2. By utilizing the detachable insertion and assembly between the insertion edge 4 and the slot 3, the funnel 2 can be easily installed and removed from the main body 1.

[0032] When the funnel 2 is assembled, the insert edge 4 slides toward the slot 3 and acts on the elastic plunger, so that the elastic plunger moves elastically and elastically avoids each other with the insert edge 4, so that the funnel 2 can be assembled smoothly; when the funnel 2 continues to slide toward the slot 3 to a certain position, the elastic plunger separates from the insert edge 4 and elastically resets, and locks in the concave hole 5, so as to realize the assembly of the funnel 2.

[0033] When disassembling funnel 2, simply reverse the above process.

[0034] The disassembly and assembly direction of funnel 2 is as follows: Figure 1 As indicated by the arrow.

[0035] This embodiment utilizes the elastic movement of the elastic plunger, enabling it to elastically avoid and lock with the insertion edge 4 and the recessed hole 5, thereby effectively ensuring the limiting and fixing between the funnel 2 and the main body 1, replacing the disadvantage of the interference fit between the funnel 2 and the main body 1 in the prior art, and thus improving the product's stability, service life, and user experience.

[0036] The slot 3 is provided with a positioning hole. The elastic plunger includes an elastic element 6 and a plunger 7. The elastic element 6 is positioned on the positioning hole. The plunger 7 is elastically extended and retracted on the positioning hole through the elastic element 6, and during elastic extension and retraction, it avoids or locks with the concave hole 5.

[0037] In this embodiment, the positioning function of the positioning hole is used to enable the elastic element 6 to be positioned on the positioning hole. At the same time, the plunger 7 can also elastically extend and retract on the positioning hole through the elastic force of the elastic element 6, so that the plunger 7 can avoid or lock with the concave hole 5.

[0038] The end of the plunger 7 that elastically expands and contracts on the positioning hole is a raised semi-circle, and the concave hole 5 is a recessed semi-circle.

[0039] In this embodiment, the protruding semi-circular end of the plunger 7 and the recessed semi-circular hole 5 can both lock together and separate from each other, thus facilitating the assembly and disassembly of the funnel 2.

[0040] The elastic plunger also includes a bracket 8, which is detachably positioned on the positioning hole. The elastic element 6 is positioned on the bracket 8, and the plunger 7 elastically extends and retracts on the positioning hole and the bracket 8 through the elastic element 6.

[0041] The support assembly function of the bracket 8 is utilized so that the bracket 8, the elastic element 6, and the plunger 7 can form a modular component elastic plunger. The elastic plunger can be directly positioned on the positioning hole, making assembly convenient.

[0042] The elastic element 6 is a compression spring, with one end acting elastically on the bracket 8 and the other end acting elastically on the plunger 7.

[0043] The plunger 7 moves elastically toward the outside of the positioning hole and the bracket 8 through the elastic force of the elastic element 6, so that the plunger 7 is always locked with the concave hole 5 during the assembly of the funnel 2, ensuring the assembly stability of the funnel 2.

[0044] The insert edge 4 extends horizontally along the top edge of the funnel 2, thereby enabling the funnel 2 to be stably supported on the slot 3 by the insert edge 4.

[0045] The recessed hole 5 is located on the bottom or surface of the insertion edge 4.

[0046] The resilient plunger can be detachably mounted on the lower or upper side of slot 3.

[0047] In this embodiment, the recessed hole 5 is located on the bottom surface of the insertion edge 4 to prevent foreign objects from clogging the recessed hole 5. Correspondingly, the elastic plunger is detachably mounted on the lower side of the slot 3. Since the elastic plunger is detachable, the user can select elastic elements 6 with different elastic forces. When the elastic force of the elastic element 6 is larger, the funnel 2 requires a larger force to be applied to achieve disassembly and assembly. When the elastic force of the elastic element 6 is smaller, the funnel 2 requires a smaller force to achieve disassembly and assembly, thus meeting the disassembly and assembly needs of different users for the funnel 2.

[0048] In addition, when the plunger 7 and the concave hole 5 are elastically locked together, they will produce a certain amount of vibration and sound, so that the user knows that the funnel 2 is assembled in place, which greatly improves the user experience.

[0049] A filter screen 9 is provided on the funnel 2 to block the coffee powder placed on the funnel 2.

[0050] A handle 10 is also provided on the outside of the funnel 2, and it is detached and installed on the main body 1 through the handle 10, so as to facilitate the user to detach and install the funnel 2.

[0051] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
