[0027] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1 to 6 As shown, the funnel structure of the utility model comprises a handle 1, a funnel 2 and a filter cup assembly 3, one end of the handle 1 is fixedly connected to the funnel 2, a first inner cavity 20 is formed in the funnel 2, the filter cup assembly 3 is detachably installed in the first inner cavity 20, a liquid spraying hole 31 is provided at the bottom of the filter cup assembly 3, a protruding block 21 is provided on the bottom plate of the first inner cavity 20, a milk foam plate 22 is provided on the protruding block 21, and the milk foam plate 22 is arranged corresponding to the liquid spraying hole 31. In this way, by providing the protruding block 21 on the bottom plate of the first inner cavity 20, the milk foam plate 22 is provided on the protruding block 21, and the milk foam plate 22 is arranged corresponding to the liquid spraying hole 31, when the coffee liquid is sprayed from the liquid spraying hole 31 of the filter cup assembly 3, the coffee liquid is sprayed on the milk foam plate 22, and more foam can be generated by impact, thereby realizing the milk foam function of the coffee liquid.

[0029] In this embodiment, the milk foam plate 22 is located directly below the liquid spray hole 31, and the liquid spray hole 31 is spaced apart from the milk foam plate 22. This arrangement provides a better milk foaming effect. In practical applications, the diameter of the liquid spray hole 31 is 0.3 mm, and the diameter of the milk foam plate 22 is 5 mm, so that the milk foaming efficiency is more sufficient.

[0030] In this embodiment, a groove is provided on the end of the protruding block 21, and the milk foam plate 22 is located in the groove. In this way, the groove can prevent coffee liquid from splashing. In practical applications, the depth of the groove is 1.3 mm.

[0031] In this embodiment, the bottom of the protruding block 21 is provided with a liquid outlet 23, and a diverter 24 is fixed on the bottom outer wall of the funnel 2. The liquid outlet 23 is connected to the inlet of the diverter 24 and forms a guide channel 27. The outlet of the diverter 24 is provided with a guide groove 1 25 and a guide groove 2 26 connected to the guide channel 27. The guide groove 1 25 and the guide groove 2 26 are symmetrically arranged. In this way, the coffee liquid after milk foam flows out from the liquid outlet 23 into the guide channel 27, and then the coffee liquid can be evenly diverted through the guide groove 1 25 and the guide groove 2 26. In actual application, the aperture of the guide channel 27 is larger than the aperture of the liquid outlet 23, so that the pressure of the coffee liquid when it is discharged is small, and the coffee liquid discharged through the guide groove 1 25 and the guide groove 2 26 can be prevented from splashing.

[0032] In this embodiment, the bottom plate of the first inner cavity 20 is a concave first arc bottom plate, and a protrusion 21 is provided at the center of the first arc bottom plate. This arrangement allows the coffee liquid after milk frothing to be gathered at the liquid outlet 23 along the concave arc surface, thereby making the coffee liquid more fully discharged into the guide channel 27, thereby preventing liquid from being retained in the first inner cavity 20.

[0033] In this embodiment, the opening of the filter cup assembly 3 is provided with a flange 34, and the filter cup assembly 3 can be detachably hung on the opening of the funnel 2 through the flange 34, and the bottom of the filter cup assembly 3 is suspended in the first inner cavity 20. This arrangement is convenient for loading and unloading, and is convenient for later disassembly and cleaning; and when the filter cup assembly 3 is assembled on the funnel 2, the flange 34 is used to limit the position, so that the bottom of the filter cup assembly 3 is spaced from the bottom of the first inner cavity 20 to form a milk foam space.

[0034] In this embodiment, a sealing ring 35 is provided between the outer wall of the filter cup assembly 3 and the inner wall of the first inner cavity 20. This arrangement prevents the coffee liquid after milk foaming from overflowing from the gap between the outer wall of the filter cup assembly 3 and the inner wall of the first inner cavity 20.

[0035] In this embodiment, the filter cup assembly 3 includes a filter cup 32 and a filter plate 33. A second inner cavity 30 is formed in the filter cup 32. The filter plate 33 is detachably installed in the second inner cavity 30. The filter plate 33 is spaced apart from the bottom plate of the second inner cavity 30. The filter plate 33 is provided with a plurality of filter holes, which are arranged corresponding to the liquid spraying holes 31. This arrangement is convenient for loading and unloading, and is convenient for later disassembly and cleaning. It should be noted that the filter plate 33 is spaced apart from the bottom plate of the second inner cavity 30. The coffee liquid passes through the filter holes of the filter plate 33 and then is sprayed out through the liquid spraying holes 31, which can reduce the water flow pressure of the coffee liquid and further prevent the coffee liquid from splashing.

[0036] In this embodiment, the bottom plate of the second inner cavity 30 is a concave second arc bottom plate, and a liquid spraying hole 31 is provided at the center of the second arc bottom plate. This arrangement allows the coffee liquid to gather at the liquid spraying hole 31 along the concave arc surface, thereby making the coffee liquid sprayed into the first inner cavity 30 more fully, and preventing liquid from being retained in the second inner cavity 30.

[0037] In this embodiment, the filter plate 33 is a flat plate, and a raised fence 36 is provided on the outer edge of the filter plate 33, and the outer wall of the fence 36 abuts against the inner wall of the second inner cavity 30. This arrangement can make the coffee liquid filter more fully and the extraction effect better.

[0038] It should be noted that the filter cup structure in the traditional funnel structure usually uses a single-layer filter cup. If too coarse coffee powder is used when brewing coffee, the pressure will be difficult to reach 7-9 Bar. Therefore, the filter cup assembly 3 described in the utility model improves the single-layer filter cup into a double-layer filter cup assembly 3 (including a double-layer filter cup composed of a filter cup 32 and a filter plate 33). With this arrangement, the pressure can reach 7-9 Bar without adding coffee powder. If the pressure is too high, if there is no milk foam plate 22 under the filter cup assembly 3, the coffee liquid will spray everywhere. Therefore, the milk foam plate 22 described in the utility model is arranged under the filter cup assembly 3. In addition to producing milk foam, it also has the effect of preventing coffee liquid from splashing.

[0039] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which belong to the protection scope of the present invention.
