Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, specifically to a funnel assembly for a coffee machine. Background Technology

[0002] Currently, traditional coffee machines use metal funnels and filter cups to extract coffee. After extraction, the coffee flows through the bottom of the funnel to the spout before flowing into the coffee cup.

[0003] For example, the Chinese utility model patent "A High-Pressure Funnel Device for Measuring Weight" with patent application number CN202221419961.2 (publication number CN217442658U) discloses a funnel device including a handle, a funnel, and a filter assembly mounted on the funnel. The handle is in the shape of a rod that is easy to hold. The funnel is detachably installed at the front end of the handle. The top of the funnel is an open structure. The filter assembly is installed from the top of the funnel. The bottom of the funnel is provided with a water outlet structure.

[0004] However, in the above method, the high-temperature coffee liquid will inevitably come into contact with the metal funnel during the extraction process, resulting in a very low coffee liquid temperature and reducing the quality of the coffee. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a funnel assembly for a coffee machine that can prevent the coffee liquid temperature from dropping, in light of the existing technology.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problem is: a funnel assembly for a coffee machine, comprising:

[0007] The funnel body is hollow inside and has an open top; and

[0008] The filter cup is located inside the funnel body, and has multiple filter holes arranged at intervals on its bottom wall;

[0009] The feature is that: the bottom wall of the filter cup has a downwardly protruding peak, and the funnel body has a relief opening at the position opposite to the peak.

[0010] In order to increase the holding capacity of the filter cup, the bottom wall inside the filter cup has a recessed portion at the position corresponding to the peak.

[0011] To facilitate the processing of the peaks and recesses, the bottom wall of the filter cup is partially pressed downwards to form the peaks and recesses.

[0012] To facilitate the smooth flow of coffee liquid along the surface of the peak, the surface of the peak is curved.

[0013] To facilitate the diversion of coffee liquid, the number of peaks is at least two, and the lowest points of each peak are arranged at intervals.

[0014] To ensure the smooth flow of coffee liquid between the two peaks, the two adjacent peaks are smoothly transitioned by an arc surface.

[0015] In practical applications, it is preferable to have one or two peaks. If there are too many peaks, it will be inconvenient to receive the coffee liquid.

[0016] Preferred option 1: The number of peaks is two, and the lowest points of the two peaks are respectively centrally located on the left and right sides of the bottom wall of the filter cup.

[0017] Preferred option 2: The number of peaks is one, and the lowest point of the peak is centrally located on the bottom wall of the filter cup.

[0018] To facilitate the processing of the relief opening, the bottom of the funnel body has an opening to form the relief opening.

[0019] To facilitate the placement and removal of the filter cup, the top periphery of the filter cup is bent outward to form a raised edge, which rests on the top periphery of the funnel body.

[0020] Compared with the prior art, the advantages of the present invention are as follows: by setting a downwardly convex peak on the bottom wall of the filter cup and setting a relief opening at the position of the funnel body directly opposite the peak, during extraction, the coffee liquid in the filter cup will flow outward through the filter holes, and then converge along the bottom wall of the filter cup to the lowest point of the peak. Finally, under the action of gravity, it falls vertically and is collected into the corresponding coffee cup through the relief opening of the funnel body. During this process, the coffee liquid will not come into contact with the funnel body, so it will not lower the coffee liquid temperature, thereby ensuring the coffee quality.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figures 1 to 3 The image shows a first preferred embodiment of the funnel assembly for a coffee machine according to the present invention. The funnel assembly includes a funnel body 1, a filter cup 2, and a handle 3.

[0029] The funnel body 1 is hollow inside, with openings at the top and bottom, and the bottom opening forms a clearance opening 11.

[0030] The filter cup 2 is located inside the funnel body 1 and is used to hold coffee powder. Specifically, the top periphery of the filter cup 2 is bent outward to form a raised edge 20, which rests on the top periphery of the funnel body 1; the bottom wall of the filter cup 2 has a plurality of filter holes 21 arranged at intervals; the bottom wall of the outer side of the filter cup 2 has a downwardly convex peak 22, which is directly opposite the aforementioned relief opening 11, and the surface of the peak 22 is arc-shaped; the bottom wall of the inner side of the filter cup 2 has a concave recess 23 at a position corresponding to the peak 22. In this embodiment, the aforementioned peak 22 and concave recess 23 are formed by pressing a portion downward from the bottom wall of the filter cup 2, so the thickness of the bottom wall of the filter cup 2 is basically the same everywhere; there are two peaks 22, and the lowest points of the two peaks 22 are respectively centrally arranged on the left and right sides of the bottom wall of the filter cup 2, and the two adjacent peaks 22 are smoothly transitioned by an arc surface.

[0031] The handle 3 is inserted into the side of the funnel body 1 for easy gripping by the user.

[0032] Example 2:

[0033] like Figure 4 and Figure 5 The image shows a second preferred embodiment of the funnel assembly for a coffee machine according to the present invention. The difference from Embodiment 1 is that:

[0034] In this embodiment, there is one peak 22, and the lowest point of the peak 22 is centrally located on the bottom wall of the filter cup 2.

[0035] Taking Example 1 as an example, the working principle of the present invention is as follows: When the coffee machine is extracting coffee, the user only needs to place the coffee cup directly below the lowest point of the peak 22. The coffee liquid in the filter cup 2 will flow out through the filter hole 21, and then flow along the bottom wall of the filter cup 2 and converge to the lowest point of the two peaks 22. Finally, it falls vertically under the action of gravity, passes through the relief port 11 of the funnel body 1 and is collected into the corresponding coffee cup. During this process, the coffee liquid will not come into contact with the funnel body 1, so it will not reduce the coffee liquid temperature, thereby ensuring the coffee quality. The funnel assembly has a simple structure, is easy to assemble, saves costs, has high reliability, and is easy to use in industrial applications.
