Description

Technical Field

[0001] The utility model relates to the technical field of coffee brewing auxiliary tools, in particular to a paper press and a coffee brewing tool component. Background Art

[0002] Coffee beans are brewed after being ground. When brewing, filter paper is generally used. Cake filter paper and cone filter paper are generally used. Among them, the water flow of cone filter paper is relatively fast, and the 360-degree all-round flow penetration can extract the soluble substances in coffee very well. However, due to the fast water flow, it is easy to break through the powder layer, and the soaking ability is weak, resulting in a poor taste of coffee. The periphery of the cake filter paper has creases and forms guide bones, which helps to even out the water flow. Even if water is injected to the edge of the filter paper, the water flow must pass through the coffee powder layer to reach the drain hole. Using cake filter paper can increase the soaking capacity of the filter cup and help improve the taste and mellowness of coffee. Therefore, drinkers who prefer the taste of coffee generally use cake filter paper. When brewing coffee with cake filter paper, the guide bones on the edge of the cake filter paper are easily deformed under hot water brewing, and some areas are separated from the filter cup. Therefore, when brewing, the operator needs to be very skilled and the operator requirements are relatively high. Summary of the invention

[0019] The utility model is described in detail below with reference to the accompanying drawings.

[0020] Example: See Figures 1 to 3 A paper press, comprising: a central connecting part 1, the side of the central connecting part 1 is connected to a plurality of paper pressing blocks 2 distributed in a ring shape, the paper pressing blocks 2 include a paper pressing part 21 for abutting against filter paper, and the side of the paper pressing part 21 includes an inclined pressing surface 22 with the lower end inclined inwardly.

[0021] In the prior art, a plurality of raised crease lines are provided on the side of the cake filter paper, which form guide bones, and a concave drainage part is formed between adjacent guide bones; when brewing coffee, hot water flows downward along the drainage part; the hot water extracts the coffee in the coffee powder, and enters the filter cup through the filter paper, and finally flows into the coffee container connected to the filter cup; in this process, the cake filter paper is not evenly impacted by the hot water, and there is a gap between the cake filter paper and the filter cup, and the coffee powder will be mixed with gas during the extraction process, and the gas may overflow outward through the gap; if there is too much gas, the cake filter paper will be deformed, part of the drainage part may be separated from the filter cup, and the drainage part will be deformed, thereby affecting the subsequent brewing effect.

[0022] When the technical solution is used, it is used together with cake filter paper and filter cup. First, put the cake filter paper into the filter cup; then use the paper press to press the filter paper; specifically, the inclined pressure surface 22 on the paper press block 2 abuts against the surface of the drainage part, and the surface of the drainage part is also inclined; when the inclined pressure surface 22 abuts against the surface of the drainage part, the entire or most of the inclined pressure surface 22 abuts against the drainage part, so that the drainage part is basically shaped and the variable amount is very small; during the brewing process, even under the flushing of hot water and the push of bubbles, it will basically not deform, so as not to affect the subsequent brewing effect of coffee powder.

[0023] See also Figure 3 Furthermore, the inclination angle of the oblique pressure surface 22 is A, and the range of A is: 55 degrees-65 degrees.

[0024] The filter cup generally adopts a V60 filter cup or a cake filter cup, and the inner side surface inclination angle of the V60 filter cup and the cake filter cup is about 60 degrees; when in use, the filter paper fits the filter cup; the paper press presses the filter paper, and the filter paper needs to be abutted against the inner side surface of the filter cup, so that the filter paper and the inner side surface of the filter cup fit closely; therefore, the inclination angle of the inclined pressure surface 22 is set to 55 degrees-65 degrees; preferably 60 degrees.

[0025] See also Figure 3 Further, the paper pressing block 2 also includes a main guide portion 23, and the side surface of the main guide portion 23 includes a guide surface 24 with a lower end inclined outward.

[0026] When in use, the paper presser is in contact with the filter paper, and then wetted with water so that the filter paper fits the filter cup; secondly, coffee powder is filled between the paper presser and the filter paper; finally, hot water is poured between the paper presser and the filter paper; when pouring the hot water, the hot water will flow in along the side of the paper press block 2; in order to avoid splashing of hot water, a guide surface 24 is set on the paper press block 2 in the present application.

[0027] Preferably, an arc surface 25 is provided between the guiding surface 24 and the inclined pressure surface 22 .

[0028] After the curved surface 25 is provided, during brewing, hot water can flow along the guide surface 24 and the curved surface 25 to soak the cake filter paper, thereby reducing the impact of the hot water on the cake filter paper.

[0029] See also Figure 2 , Figure 3 The central connecting portion 1 comprises a hollow column, and the paper pressing block 2 is connected to the side of the hollow column.

[0030] In order to save costs and reduce the weight of the central connecting part 1, the present application sets the central connecting part 1 as a hollow column.

[0031] See also Figure 1 , Figure 3 ; Further, the paper pressing block 2 includes an upper guide portion 26, the upper end of the upper guide portion 26 is connected to the upper end of the hollow column, and the lower end of the upper guide portion 26 is connected to the upper end of the main guide portion 23; the side surface of the upper guide portion 26 is inclined, and the lower end of the side surface is inclined outward, and the inclination angle is greater than the inclination angle of the side surface of the main guide portion 23.

[0032] When designing the paper pressing block 2, the upper end of the paper pressing block 2 should be lower than the upper end surface of the filter cup, in order to reduce the mass of the paper pressing block 2 and reduce the cost; the paper pressing block 2 is provided with an upper guide portion 26 and a main guide portion 23; the inclination angle of the upper guide portion 26 is set to be relatively large; preferably, the upper end of the upper guide portion 26 is provided with an upper inclined surface.

[0033] See also Figure 3 The hollow column comprises an upper hollow column 1 and a lower hollow column 13, and a conical ring 12 is provided between the upper hollow column 1 and the lower hollow column 13.

[0034] The hollow column is divided into three parts, and the outer diameter of the lower hollow column 13 is larger than the outer diameter of the upper hollow column 1 , which can effectively reduce the weight of the paper pressing part 21 .

[0035] A coffee brewing device assembly comprises: a filter cup, cake filter paper and the above-mentioned paper press. The cake filter paper is arranged inside the filter cup, and the paper pressing part 21 of the paper press abuts against the drainage part of the cake filter paper.

[0036] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
