Implementation

[0016] Now, in conjunction with the accompanying drawings, the structure and use of the utility model are further described. Figure 1-Figure 5 As shown, the etching mesh 2 of the coffee machine filter assembly is in an inverted cone shape, a woven mesh 3 is provided on the inner conical surface of the etching mesh, a bottom mesh assembly is provided at the bottom of the etching mesh, a bottom etching mesh 5 and a bottom woven mesh 7 are provided at the bottom filter hole in the bottom cover 4 of the bottom mesh assembly, and the top of the etching mesh is connected to the bottom inner diameter of the orifice of the upper ring 1 through a pressure ring 8 of the inner diameter of the orifice. Its specific structure is as follows: the above-mentioned etching mesh and pressure ring are sequentially inserted into the upper ring, the bottom hole diameter of the upper ring is smaller than the top hole diameter and is punched and bent inward, the top of the etching mesh is spot-welded with the bottom hole outer diameter of the pressure ring through the hole inner diameter, and the bottom ring surface of the upper ring is spot-welded with the top hole ring surface in the pressure ring; the bottom cover is inserted and fixed to the bottom hole inner diameter of the etching mesh, the bottom hole inner diameter of the etching mesh is spot-welded with the outer diameter of the bottom cover, a circle of the gasket 6 is spot-welded with the bottom etching mesh, and the bottom braided mesh is arranged on the top of the gasket, and the above-mentioned pressure ring, gasket, bottom etching mesh, bottom cover, etching mesh, and upper ring are stainless steel parts. The top hole of the upper ring is provided with an outer flange formed by punching and bending outward, and the inner diameter between the top hole and the bottom hole of the upper ring is provided with a transition edge 101 formed by punching and shrinking toward the bottom; the top hole edge and the bottom hole edge of the etching mesh are respectively provided with a hole-free edge 201.

[0017] Thus, the upper ring is spot welded to the etched mesh; the etched mesh is spot welded to the pressure ring; the etched mesh is spot welded to the bottom cover; the gasket is spot welded to the bottom etched mesh. In the above built-in welding method, the upper ring parts are exposed to the outside. The welding method adopted by the coffee machine filter assembly does not completely rely on the welding points to support the strength of the components, but increases the strength from the structure, weakens the influence of the welding points on the strength of the overall assembly, and ensures the stability of mass production.
