[0026] In an embodiment of the present application, as Figures 1 to 7 shown, a coffee machine filter element includes a housing 1 for accommodation, a filter material 2, and a water inlet cover 3. A accommodation chamber 101 is formed on the housing 1, and a water outlet hole 102 communicating with the accommodation chamber 101 is formed at its bottom; the filter material 2 is arranged in the accommodation chamber 101 for filtering water; the water inlet cover 3 is arranged on the upper side of the housing 1, and a water inlet passage 301 is formed thereon; the coffee machine filter element further includes a filter material protection bottom layer 4 arranged on the lower side inside the accommodation chamber 101, a downward water-passing plate 5 arranged on the upper side inside the accommodation chamber 101 and having water-passing holes 501, and a filter material protection top layer 6 embedded inside the downward water-passing plate 5; a water inlet diffusion space 300 is arranged between the water inlet cover 3 and the downward water-passing plate 5, and the water inlet diffusion space 300 communicates with the water inlet passage 301 and the water-passing holes 501; a downward convex portion 103 protruding downward and located outside the water outlet hole 102 is further arranged on the lower side outside the housing 1.

[0027] The coffee machine filter element of the present application contains the filter material 2 through the accommodation chamber 101, and then passes through the filter material protection top layer 6 and the filter material protection bottom layer 4 arranged on the upper and lower sides of the filter material 2. These two protection structures can not only effectively prevent the filter material 2 from being damaged and lost during the filtration process, but also ensure the uniform filtration of water. When water enters the water inlet diffusion space 300, it can be evenly contacted with the filter material 2 through the cooperation of the water inlet diffusion space 300 and the water passing holes 501, so as to further improve the filtration efficiency. Finally, through the design of the lower convex part 103 on the outside of the lower side of the accommodation shell 1, the water outlet height of the water outlet hole 102 at the bottom of the accommodation shell 1 is raised, so as to improve the water outlet efficiency, and further realizes that not only can the filter material be fully contacted to improve the filtration effect, but also the water outlet speed can be further increased to meet the use requirements of high-efficiency coffee making.

[0028] Furthermore, there are multiple lower convex parts 103, and they are arranged at intervals along the circumferential direction of the accommodation shell 1. The purpose is to raise the water outlet height of the water outlet hole 102 at the bottom of the accommodation shell 1 so as to improve the water outlet efficiency.

[0029] Furthermore, a limiting step 1011 for limiting the downward pressure water passing plate 5 is provided on the upper side inside the accommodation chamber 101. The purpose is to limit and place the downward pressure water passing plate 5.

[0030] Furthermore, there are multiple water passing holes 501, and a water guiding inclined surface 5011 inclined inward is provided on the upper side of each water passing hole 501. The advantage is that the water passing holes 501 are formed into a shape with a wider upper part and a narrower lower part, which is beneficial to quickly introduce water flow into the accommodation chamber 101 to further improve the water filtration efficiency.

[0031] Furthermore, there are multiple water outlet holes 102, and an outer inclined surface 1021 inclined outward is provided on the lower side of each water outlet hole 102. The advantage is that the water outlet holes 102 are formed into a shape with a narrower upper part and a wider lower part, which is beneficial to accelerating the water outlet efficiency.

[0032] Furthermore, an upward convex column 30 is provided on the upper side of the water inlet cover 3, and a water inlet channel 301 is opened on the convex column 30. The advantage is to adapt and connect to the water supply end of the coffee machine.

[0033] Furthermore, a downward pressing annular part 502 that protrudes downward and is located outside the water passing holes 501 is provided on the lower side inside the downward pressure water passing plate 5 for pressing down the filter material protection top layer 6;

[0034] The lower side inside the accommodation chamber 101 is provided with an upwardly protruding upper top annular portion 1012 for upwardly pressing the bottom filter layer 4. In the present application, the lower pressing annular portion 502 and the upper top annular portion 1012 can achieve better upper and lower tight wrapping of the filter material 2.

[0035] Furthermore, the filter material 2 is a filter resin, or a combination of a filter resin and one or more of carbon fiber and activated carbon, aiming to achieve a filtering effect.

[0036] Furthermore, the materials for making the bottom filter layer 4 and the top filter layer 6 are preferably non-woven fabrics, but are not limited thereto. The advantage is that they form upper and lower wrapping of the filter material 2 to prevent material leakage and at the same time achieve the effect of controlling the flow rate.

[0037] As described above, an implementation manner is provided in combination with specific content, and it is not determined that the specific implementation of the present application is only limited to these descriptions. Any approximation or similarity to the method and structure of the present application, or any technical deduction or replacement made under the premise of the concept of the present application, should be regarded as the protection scope of the present application.
