Description

A coffee filter cup

[0001] The utility model relates to a device for making coffee, in particular to a coffee filter cup. Background Art

[0002] The coffee filter cup is a commonly used device in the coffee making process. Its functions are mainly in two aspects: one is to filter coffee powder (coffee grounds), and the other is to control the fusion of water flow, coffee and air during the filtration process, thereby improving the aroma of coffee to a certain extent.

[0003] Universal coffee filter cups have a simple structure, with a filter replacing the bottom of the cup. However, this design has the disadvantage that different types of coffee, or coffee powders with varying grind levels, require different filters to achieve varying filtration efficiency and flavor. However, the filter of a universal filter cup is fixedly connected to the cup body, making it difficult to flexibly adjust to varying coffee powders. Furthermore, the filter is a key component to clean, making it much more susceptible to wear and damage than the cup itself. If the filter of a universal filter cup is damaged, the entire cup becomes unusable, resulting in waste.

[0004] Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a coffee filter cup, comprising: a cup body, a filter screen and a cup holder; the bottom of the cup body is hollowed out to form a first opening, a second opening is provided in the middle of the cup holder, and a detachable fixed connection is provided between the first opening and the second opening; when the cup body and the cup holder are in a connected state, the edge of the filter screen is clamped by the cup body and the cup holder.

[0006] Preferably, in the above-mentioned coffee filter cup, the detachable fixed connection method includes a thread, a snap or an interference fit.

[0007] Preferably, in the above-mentioned coffee filter cup, the cup body includes an inner wall and an outer wall, and a hollow is formed between the inner wall and the outer wall.

[0008] Preferably, in the above-mentioned coffee filter cup, the hollow portion is evacuated to a vacuum state.

[0009] Preferably, in the above-mentioned coffee filter cup, the filter screen is a three-dimensional structure with a low middle and high periphery, and a multi-step transition in the middle.

[0010] Preferably, in the above-mentioned coffee filter cup, filter holes of different shapes and / or densities are provided on each level of the steps.

[0011] The coffee filter cup of this utility model not only allows for flexible replacement of the filter according to the type of coffee and taste requirements, but also improves the contact between air, coffee powder, and water, thereby improving the coffee flavor. According to the preferred embodiment, it also effectively avoids safety hazards such as splashing boiling water and scalding the cup, thus having high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG1 is an exploded view of an embodiment of a coffee filter cup of the present invention;

[0013] FIG2 is a longitudinal sectional view of the embodiment of FIG1 in an assembled state;

[0014] FIG3 is a side view of the filter screen 2 in the embodiment of FIG1 . DETAILED DESCRIPTION

[0015] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0016] Please refer to the accompanying drawings below. It should be noted that the illustrations provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components relevant to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be varied at will, and the component layout may be more complex. Unless otherwise specified, terms such as "up," "down," "left," and "right" used herein to indicate directions are based on the perspective of the observer in the accompanying drawings.

[0017] Figure 1 shows an exploded view of an embodiment of a coffee filter cup according to the present invention. The coffee filter cup comprises a cup body 1, a filter screen 2, and a cup holder 3. The bottom of the cup body 1 is hollowed out to form an opening, and the outer wall of the opening is provided with threads 11. The cup holder 3 has an opening in the center, and the inner wall of the opening is provided with threads 31 that mate with threads 11, thereby forming a removable, fixed connection between the cup body 1 and the cup holder 3. The center portion of the filter screen 2 is provided with a filter hole. The assembled state of the cup body 1, filter screen 2, and cup holder 3 is shown in Figure 2. When assembled, the cup body 1 and cup holder 3 clamp the edges of the filter screen 2, thereby securing the filter screen 2 to the bottom of the cup body 1.

[0018] The cup body 1 in this embodiment has a double-layer design, as shown in FIG2 . A space 11 is formed between the inner and outer walls. The space 11 can provide insulation, making it easier to hold. To enhance the insulation effect, the space 11 can also be evacuated to a vacuum or quasi-vacuum.

[0019] Figure 3 shows a side view of a preferred embodiment of the filter 2. In conjunction with Figure 2 , it can be seen that the filter 2 in this example differs from a traditional flat filter. Instead, it is configured as a three-dimensional structure with a low center and high perimeter, with a multi-step transition in the middle. The filter holes on steps 21 to 23 can be independently configured in terms of shape and density. Compared to a traditional flat filter, the stepped structure increases the contact area between the coffee powder and the air, which helps extract the aroma from the coffee powder and improves the coffee taste. Furthermore, the three-dimensional design with a low center and high perimeter prevents the formation of bubbles during pouring, especially in boiling water. Reducing or preventing bubble formation can prevent the splattering of boiling water and coffee powder caused by bubble bursting.

[0020] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without departing from the spirit and scope of the present invention. For example, the threads 11 and 31 in the embodiment of FIG1 are merely one way of implementing a detachable fixed connection. Those skilled in the art will appreciate that replacing them with buckles or even using only interference fits all fall under the same concept. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
