Description

Technical Field

[0001] This utility model belongs to the field of coffee equipment technology, specifically relating to an elastic secondary water distribution mesh for a pressure coffee machine. Background Technology

[0002] When making coffee with a pressure espresso machine, many people install a secondary water separator on top of the coffee grounds to prevent the coffee powder from shifting in the upper part of the filter basket and to improve coffee quality. Currently, this secondary water separator is generally a thin sheet with multiple small holes evenly distributed on its surface. This type of separator relies on its own weight to compress the coffee grounds, resulting in insufficient pressure and poor performance. It is also inconvenient to remove and operate, making it difficult for consumers. Summary of the Invention

[0003] The purpose of this invention is to provide an elastic secondary water distribution mesh for a pressure coffee machine, aiming to address the technical deficiencies in the existing technology.

[0004] The technical solution for achieving the purpose of this utility model is an elastic secondary water distribution screen for a pressure coffee machine, comprising a water distribution screen body, a conical spring, and a small upper cover. The conical spring is connected to the middle of the top surface of the water distribution screen body, and the large diameter end of the conical spring is set upward. The small upper cover is set at the top of the conical spring. The bottom edge of the small upper cover is integrally formed with a downwardly protruding inward folded edge, and the top large diameter end of the conical spring is tightened against the inner wall of the inward folded edge.

[0005] A further preferred embodiment is that the bottom small-diameter end of the conical spring is riveted to the water distribution mesh body by means of rivets.

[0006] A further preferred embodiment is that the water distribution mesh body is uniformly provided with a number of small holes.

[0007] A further preferred embodiment is that the small top cover has several holes.

[0008] A further preferred embodiment is that the conical springs can lie in the same plane after extreme compression.

[0009] A further preferred embodiment is that the water distribution mesh, the small top cover, and the conical spring are all made of stainless steel.

[0010] This invention has several advantages: its structure is reasonably designed, with a conical spring between the water distribution mesh and the small top cover, which reliably compresses the coffee powder. The coffee powder is compressed under the spring pressure, which helps prevent the powder particles on the top from moving. The compressed spring does not occupy axial space, and the overall structure occupies little space. It is suitable for different amounts of coffee powder, has good versatility and strong applicability, and is also convenient for handling, resulting in better coffee. The structure is simple and the manufacturing cost is low. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] See Figures 1 to 3 As shown, an elastic secondary water distribution screen for a pressure coffee machine includes a water distribution screen body 1, a conical spring 2, and a small upper cover 3. The conical spring 2 is connected to the center of the top surface of the water distribution screen body 1, with the large-diameter end of the conical spring 2 facing upwards. The small upper cover 3 is located at the top of the conical spring 2. The bottom edge of the small upper cover 3 has an integrally formed downward-protruding inward-folded edge, and the top large-diameter end of the conical spring 2 is tightened against the inner wall of the inward-folded edge. In this embodiment, the bottom small-diameter end of the conical spring 2 is riveted and fixed to the water distribution screen body 1 by rivets 4. Furthermore, the water distribution screen body 1 has a plurality of small holes evenly distributed on it. The small upper cover 3 has a plurality of holes. The small holes on the water distribution screen body 1 allow water to be evenly distributed on the surface of the coffee powder, while the holes on the small upper cover 3 allow water to pass freely, improving the stability of use.

[0017] As per the attached instructions Figure 3As shown, the coffee filter bowl 9 is placed inside the coffee powder scoop 8, and coffee powder 10 is added to the coffee filter bowl 9 and pressed flat. The elastic secondary water distribution mesh is then placed above the coffee powder 10 and installed on the water outlet head 6 of the coffee machine. At this point, the small top cover 3 rests against the lower end of the water outlet mesh of the coffee machine itself, the upper end of the conical spring 2 rests against the lower end of the small top cover 3, and the lower end of the conical spring 2 presses firmly against the upper end of the water distribution mesh body 1, reliably pressing the coffee powder 10 and effectively preventing it from floating and moving, thus preventing channeling during extraction. The sealing ring 7 is fitted around the water outlet mesh 5 of the coffee machine and pressed tightly against the upper surface of the coffee filter bowl 9. During extraction, water flows through the small holes of the water distribution mesh body 1, evenly passing through the coffee powder 10, ensuring uniform extraction of the coffee powder 10 and improving coffee quality.

[0018] like Figure 2 and Figure 3 As shown, the conical spring 2 can be in the same plane after extreme compression. Therefore, it does not occupy axial space during use. When compressed, the thinnest thickness of the small upper cover 3 and the water distribution mesh body 1 does not exceed 2mm, which does not affect the original coffee machine's powder capacity and has strong versatility.

[0019] Even when the coffee filter 9 contains a small amount of coffee powder, it can still reliably compress the coffee powder 10 under the pressure of the conical spring 2, making it highly versatile. Compared to ordinary water separators that rely on their own weight to compress the coffee powder 10, this method can reliably compress the coffee powder and increases the compressing force, making it more versatile.

[0020] In this embodiment, the small top cover 3 helps to improve the overall aesthetics of the product and makes it easier for users to pick up and handle. In addition, the holes on the small top cover 3 not only increase the decorative effect, but also facilitate the passage of water.

[0021] In this embodiment, the tamping force of the coffee powder 10 during the extraction process is generally suitable at 0.1~1 kgf, and the wire diameter of the conical spring 2 is generally suitable at 0.8~1 mm.

[0022] Furthermore, the water distribution mesh 1, the small upper cover 3, and the conical spring 2 are all made of stainless steel.

[0023] In this embodiment, the bottom small-diameter end of the conical spring 2 is riveted and fixed to the water distribution mesh 1 by rivets 4. In practical applications, it can also be connected by screws, nuts, welding, etc., which will not be described in detail.

[0024] The structure of this utility model is reasonable. A conical spring is set between the water distribution mesh and the small upper cover, which can reliably press the coffee powder and prevent the coffee powder in the upper part from moving. The overall structure occupies little space, is suitable for different amounts of coffee powder, has good versatility and strong applicability, and is also convenient to pick up and put away. The coffee produced is better, convenient to use, simple in structure and low in manufacturing cost.
