[0001] The present application relates to the field of coffee processing, and in particular to a coffee powder bowl and a coffee machine. Background Art

[0002] At present, with the popularization of coffee culture and consumers' pursuit of coffee quality, the precision extraction powder bowl of the coffee machine plays an increasingly important role in the coffee making process. The connection structure between the powder bowl and the upper filter affects the quality of the coffee. In response to this, some manufacturers have produced a connection structure between the coffee extraction powder bowl and the upper filter.

[0003] For example, Chinese patent document CN218942898U discloses a coffee extraction powder bowl woven filter connection structure, including a single-layer coffee powder bowl, the bottom of the single-layer coffee powder bowl is integrally formed with a filter bowl bottom, the bottom surface of the filter bowl bottom is provided with filter holes, the top of the filter bowl bottom is welded with a circular woven filter, and the edge of the circular woven filter is provided with welding points.

[0004] However, the design of the coffee extraction powder bowl weaving filter screen connection structure has the following problems:

[0005] Although the above-mentioned coffee extraction powder bowl woven filter connection structure can filter the coffee powder step by step through the circular woven filter and the bottom of the filter bowl, when the user pours hot water into the center of the coffee powder bowl, the hot water will impact the coffee powder in the center of the coffee powder bowl. The coffee powder in the center is easily squeezed out of the coffee powder bowl by the impact, and the coffee powder in the center is eventually mixed into the extraction liquid, thereby affecting the taste of the coffee. Utility Model Content

[0006] The purpose of the present application is to overcome the deficiencies in the prior art and to provide a coffee powder bowl and a coffee machine for finely filtering coffee powder particles.

[0007] The purpose of this application is achieved through the following technical solutions:

[0008] A coffee powder bowl, comprising a powder bowl support and a filter assembly, wherein an opening is provided at the bottom of the powder bowl support, and the filter assembly is arranged at the opening;

[0009] The filter assembly includes an upper filter screen and a lower filter bottom plate; the lower filter bottom plate is placed at the opening, and the upper filter screen is stacked on the lower filter bottom plate; a first filter area and a second filter area are provided on the lower filter bottom plate, the first filter area is arranged at the center position of the lower filter bottom plate, and the second filter area is arranged around the first filter area; the filter port of the first filter area is staggered with the corresponding mesh of the upper filter screen, and the filter port of the second filter area is arranged opposite to the corresponding mesh of the upper filter screen.

[0010] In one embodiment, the cross-sectional area of ​​the filter opening of the first filter zone is smaller than the cross-sectional area of ​​the filter opening of the second filter zone.

[0011] In one embodiment, the filter opening of the first filter zone is circular, triangular or diamond-shaped.

[0012] In one embodiment, the filter opening of the second filter zone is rectangular and connected to a plurality of meshes of the upper filter screen.

[0013] In one embodiment, the cross-sectional area of ​​the filter opening of the first filter zone is in the range of 0.01 mm 2 -0.20mm 2 .

[0014] In one embodiment, the filter opening of the first filter zone has at least two geometric shapes.

[0015] In one embodiment, the filter bottom plate is embedded in the opening.

[0016] In one of the embodiments, a mounting groove is provided at the opening, and the mounting groove is an L-shaped groove.

[0017] In one embodiment, a sloped boss is provided on the top of the powder bowl support, and the sloped boss is protruding outward; and / or,

[0018] The inner peripheral wall of the powder bowl support is provided with a plurality of arc-shaped grooves.

[0019] A coffee machine comprises the coffee powder bowl of any one of the above embodiments.

[0020] Compared with the prior art, this application has at least the following advantages:

[0021] 1) By setting the filter assembly to have an opening at the bottom of the powder bowl support, the coffee powder can be extracted from the coffee liquid at the opening at the bottom of the powder bowl support, and the upper filter is stacked on the lower filter film. When extracting the coffee powder, the coffee powder can be first extracted through the upper filter, and a new round of extraction is performed through the lower filter film at the same time. Because the lower filter film is provided with a first filter area and a second filter area, the first filter area is arranged at the center of the lower filter film, and the second filter area is arranged around the first filter area, so that the lower filter film is divided into different filter areas. When the user pours hot water into the center of the coffee powder bowl, the filter port of the first filter area and the mesh of the upper filter are staggered, which has a stronger blocking effect on the coffee powder. Therefore, the impact force on the coffee powder at the center of the coffee powder bowl will be offset by the first filter area and the upper filter, and the hot water will impact the second filter area laterally, and the coffee powder will be slowly extracted in the second area.

[0022] 2) Compared with the coffee powder bowl in the prior art, the above-mentioned coffee powder bowl, by staggering the filter opening of the first filter area and the mesh opening of the corresponding upper filter, makes it possible for the impact force on the coffee powder at the center of the coffee powder bowl to be offset by the first filter area and the upper filter, thereby preventing the coffee powder at the center from being squeezed out of the coffee powder bowl by water during the process of pouring hot water, thereby preventing coffee powder with smaller particle size from eventually mixing into the extraction liquid.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1 As shown, a coffee powder bowl 10 of an embodiment includes a powder bowl support 100 and a filter assembly 200, wherein the powder bowl support 100 is provided with an opening 110 at the bottom, and the filter assembly 200 is arranged at the opening 110; the filter assembly 200 includes an upper filter screen 210 and a lower filter bottom film 220; the lower filter bottom film 220 is placed at the opening 110, and the upper filter screen 210 is stacked on the lower filter bottom film 220; a first filter area 2210 and a second filter area 2220 are provided on the lower filter bottom film 220, the first filter area 2210 is arranged at the center of the lower filter bottom film 220, and the second filter area 2220 is arranged around the first filter area 2210; the filter port of the first filter area 2210 is staggered with the mesh 2110 of the corresponding upper filter screen 210, and the filter port of the second filter area 2220 is arranged opposite to the mesh 2110 of the corresponding upper filter screen 210.

[0035] It can be understood that by setting the filter assembly 200 at the opening 110 at the bottom of the powder bowl support 100, the coffee powder can be extracted from the coffee liquid at the opening 110 at the bottom of the powder bowl support 100, and the upper filter 210 is stacked on the lower filter film 220. When extracting coffee powder, the coffee powder can be first extracted through the upper filter 210, and a new round of extraction is performed through the lower filter film 220. Because the lower filter film 220 is provided with a first filter area 2210 and a second filter area 2220, the first filter area 2210 is arranged at the center of the lower filter film 220, and the second filter area 2220 is arranged around the first filter area 2210, so that the lower filter film 220 is divided into different filter areas, and at the same time, the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 are staggered, so that the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 are staggered, so that the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 The diameter of the combination of the first filter area 2210 becomes smaller, and the filter port of the second filter area 2220 is arranged relative to the mesh 2110 of the corresponding upper filter 210. When the user pours hot water into the coffee powder bowl 10, the hot water will impact the coffee powder in the coffee powder bowl 10. Since the diameter of the first filter area 2210 becomes smaller, the coffee powder with smaller particle size will not be mixed into the extraction liquid. At the same time, due to the downward impact of the hot water, the extraction liquid will flow to the second filter area 2220 for extraction, and finally flow into the cup.

[0036] It can be understood that compared with the coffee powder bowl in the prior art, the above-mentioned coffee powder bowl 10 is divided into a first filter area 2210 and a second filter area 2220 on the filtering lower film 220, and the filter port of the first filter area 2210 is staggered with the mesh 2110 of the corresponding upper filter 210, so that the first filter area 2210 of the filtering lower film 220 can effectively filter the coffee powder at the center position, thereby avoiding coffee powder with smaller particle size from being mixed into the extraction liquid and affecting the coffee flavor.

[0037] like Figure 1 As shown, specifically, the cross-sectional area of ​​the filter opening of the first filter area 2210 is smaller than the cross-sectional area of ​​the filter opening of the second filter area 2220. It can be understood that by setting the filter opening of the first filter area 2210 smaller than the filter opening of the second filter area 2220, when the coffee powder is washed and extracted from the upper filter screen 210 to the filter bottom sheet 220, since the filter opening of the first filter area 2210 is smaller than the filter opening of the second filter area 2220, it is difficult for the powder to flow out from the filter opening of the first filter area 2210, and at the same time, because the extraction liquid flows to the second filter area 2220 under the impact of the water flow, the extraction speed of the coffee powder is accelerated.

[0038] like Figure 2As shown, in one embodiment, the filter opening of the first filter area 2210 is circular, triangular or diamond-shaped. It can be understood that setting the filter opening of the first filter area 2210 to be circular, triangular or diamond-shaped can adapt to the different extraction effects of different coffee powders corresponding to the filter openings of different shapes, meet the extraction requirements of different coffee powders, and thus achieve the best extraction effect of coffee powder.

[0039] like Figure 2 As shown, specifically, the filter opening of the second filter area 2220 is rectangular and connected to the meshes 2110 of the plurality of upper filter nets 210. It can be understood that the filter opening of the second filter area 2220 is rectangular, so that when the extract flows to the second filter area 2220, it helps to maintain the uniform distribution of the coffee extract during the filtration process and the stable flow to the cup, and the meshes 2110 connected to the upper filter net 210 can ensure that the water flows evenly through each filter opening, thereby improving the extraction efficiency and consistency of the coffee.

[0040] like Figure 3 As shown, in one embodiment, the cross-sectional area of ​​the filter port of the first filter zone 2210 is in the range of 0.01 mm 2 -0.20mm 2 It can be understood that the filter size range of the first filter area 2210 is set to 0.01mm 2 Up to 0.20mm 2 , the filter port of the first filter area 2210 can separate the coffee grounds and larger coffee particles from the extraction liquid, ensuring that most of the coffee particles are isolated in the first filter area 2210, thereby ensuring that there is no obvious floating residue in the brewed coffee liquid and ensuring the extraction effect of the coffee powder. Specifically, the filter port size of the first filter area 2210 can be 0.01mm 2 , 0.015mm 2 or 0.20mm 2 , which is not limited here, and those skilled in the art may also make other choices as needed.

[0041] like Figure 2 As shown, specifically, the filter opening of the first filter area 2210 has at least two geometric shapes. It can be understood that the filter opening of the first filter area 2210 has at least two geometric shapes, so that the user can choose different filter opening shapes according to different needs and the needs of different devices, so that when coffee powders of different calibers are in the first filter area 2210, they are isolated and filtered according to different shapes.

[0042] like Figure 1As shown, in one embodiment, the filter bottom plate 220 is embedded in the opening 110. It can be understood that by setting the filter bottom plate 220 embedded in the opening 110, it is convenient for the user to replace different filter bottom plates 220 according to different filtering requirements, and it is convenient to quickly install and remove the filter bottom plate 220 in the opening 110.

[0043] like Figure 4 and Figure 5 As shown, specifically, a mounting groove 1110 is provided at the opening 110, and the mounting groove 1110 is an L-shaped groove. It can be understood that the mounting groove 1110 is provided at the opening 110, so that the filter bottom plate 220 is embedded in the mounting groove 1110, and the mounting groove 1110 is an L-shaped groove, which is convenient for the filter bottom plate 220 to be quickly embedded in the mounting groove 1110, thereby improving the efficiency of assembling the coffee powder bowl 10.

[0044] like Figure 1 As shown, specifically, a sloped boss 120 is provided on the top of the powder bowl support 100, and the sloped boss 120 is convex outward. It can be understood that by providing the sloped boss 120 on the top of the powder bowl support 100 and convex outward, when the hot water flow is too large, the hot water is prevented from splashing outward, and the sloped boss 120 is convex outward, which prevents the coffee powder bowl 10 from accidentally sliding or moving off to the ground during the use of the coffee machine.

[0045] like Figure 1 As shown, in another embodiment, the inner wall of the powder bowl support 100 is provided with a plurality of arc grooves 130. It can be understood that a plurality of arc grooves 130 are provided on the inner wall of the powder bowl support 100, and the arc grooves 130 are used to be nested in the coffee machine, so that the coffee powder bowl 10 can be installed in different arc grooves 130 according to the needs to adjust the height when it is installed on the coffee machine, so as to meet the needs of the user.

[0046] A coffee machine, comprising the coffee powder bowl 10 of any of the above embodiments. It can be understood that by applying the coffee powder bowl 10 of the present application to the coffee machine, by dividing the lower filter sheet 220 into a first filter area 2210 and a second filter area 2220, and the filter opening of the first filter area 2210 is staggered with the mesh 2110 of the corresponding upper filter screen 210, the first filter area 2210 of the lower filter sheet 220 can effectively filter the coffee powder at the center position, thereby preventing the coffee powder with a smaller particle size from being mixed into the extraction liquid and affecting the coffee flavor.

[0047] Compared with the prior art, this application has at least the following advantages:

[0048] 1) By setting the filter assembly 200 at the opening 110 at the bottom of the powder bowl support 100, the coffee powder can be extracted from the coffee liquid at the opening 110 at the bottom of the powder bowl support 100, and the upper filter 210 is stacked on the lower filter film 220. When extracting coffee powder, the coffee powder can be first extracted through the upper filter 210, and a new round of extraction is performed through the lower filter film 220. Because the lower filter film 220 is provided with a first filter area 2210 and a second filter area 2220, the first filter area 2210 is arranged at the center of the lower filter film 220, and the second filter area 2220 is arranged around the first filter area 2210, so that the lower filter film 220 is divided into different filter areas, and at the same time, the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 are staggered, so that the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 are staggered, so that the filter port of the first filter area 2210 and the mesh 2110 of the upper filter 210 The diameter of the combination of the first filter area 2210 becomes smaller, and the filter port of the second filter area 2220 is arranged relative to the mesh 2110 of the corresponding upper filter 210. When the user pours hot water into the coffee powder bowl 10, the hot water will impact the coffee powder in the coffee powder bowl 10. Since the diameter of the first filter area 2210 becomes smaller, the coffee powder with smaller particle size will not be mixed into the extraction liquid. At the same time, due to the downward impact of the hot water, the extraction liquid will flow to the second filter area 2220 for extraction, and finally flow into the cup.

[0049] 2) Compared with the coffee powder bowl of the prior art, the above-mentioned coffee powder bowl 10 is divided into a first filter area 2210 and a second filter area 2220 on the filtering lower bottom plate 220, and the filter port of the first filter area 2210 is staggered with the mesh 2110 of the corresponding upper filter 210, so that the first filter area 2210 of the filtering lower bottom plate 220 can effectively filter the coffee powder at the center position, thereby preventing coffee powder with smaller particle size from being mixed into the extraction liquid and affecting the coffee flavor.

[0050] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
