Description

Technical Field

[0001] The utility model relates to the field of coffee powder tamper structures, in particular to a lever constant-force coffee powder tamper auxiliary device. Background Art

[0002] A coffee tamper, also known as a tamping hammer, is a tool used when making Italian coffee. Its main function is to compact the coffee powder in the coffee handle to form a uniform and flat surface so that hot water can be evenly extracted through the coffee powder, thereby making espresso with a uniform taste. Specifically, the pressing density of the coffee tamper has a significant impact on the quality of the coffee. The pressing density refers to the amount of pressure applied to the coffee powder by the tamper. The appropriate pressing density can ensure that the coffee powder bed is evenly compacted, so that hot water can be evenly extracted through the coffee powder. If the coffee powder bed is too loose, the water flow will pass unevenly, resulting in over-extraction of coffee powder in some areas and under-extraction in other areas, which will make the taste and flavor of the coffee unbalanced.

[0023] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] In the following description, the example details are given to provide a deeper understanding of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the utility model, and are not used to limit the utility model.

[0025] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0026] A coffee tamper, also known as a tamping hammer, is a tool used when making Italian coffee. Its main function is to compact the coffee powder in the coffee handle to form a uniform and flat surface so that hot water can be evenly extracted through the coffee powder, thereby making espresso with a uniform taste. Specifically, the pressing density of the coffee tamper has a significant impact on the quality of the coffee. The pressing density refers to the amount of pressure applied to the coffee powder by the tamper. Appropriate pressing density can ensure that the coffee powder bed is evenly compacted, allowing hot water to evenly pass through the coffee powder. During extraction, if the coffee powder bed is too loose, the water flow will pass unevenly, resulting in over-extraction of coffee powder in some areas and under-extraction in other areas, which will make the taste and flavor of the coffee unbalanced; in the prior art, the manual pressing coffee powder tamper will cause the pressing force between different pressing batches to be unable to be within a certain range, resulting in the brewing taste and flavor of coffee powder between different pressing batches being varied and unable to be unified, and although the electric press solves the above problems, it is expensive; therefore, there is an urgent need for a coffee powder tamper with a more reasonable structure to solve the above technical problems.

[0027] In order to solve the above-mentioned technical problems, the present application provides a lever constant force coffee powder pressing auxiliary device, please refer to the attached Figure 1 To Attachment Figure 4, used for compressing the powder holding space between the powder bowl 5 and the powder hammer 6, comprising a support rod 1, and a lever arm rod 2 movably connected to the non-fixed end of the support rod 1, wherein the end of the lever arm rod 2 away from the support rod 1 is provided with a counterweight block 3; further comprising a powder pressing rod 4, wherein one end of the powder pressing rod 4 is assembled on the rod surface of the lever arm rod 2, and a first lever arm distance is formed between the lever arm rod 4 and the counterweight block 3; through the cooperation of the counterweight block 3, the lever arm rod 2 and the powder pressing rod 4, the powder pressing rod 4 presses the powder hammer 6 based on the mass of the counterweight block 3 to compress the powder holding space, thereby ensuring that the powder pressing force of multiple powder pressing sequences is within the expected range, so that the taste and flavor of the extracted coffee are more uniform.

[0028] In this embodiment, the connection between the powder pressing rod 4 and the lever arm rod 2 forms a connection point, and a second lever arm distance is formed from the connection point to the end of the lever arm rod away from the counterweight block, and the ratio of the first lever arm distance to the second lever arm distance is 4:1; it is not difficult to understand that by setting the ratio between the first lever arm distance and the second lever arm distance, the pressing force formed by the powder bowl 5 and the powder hammer 6 is more uniform. In the specific scheme, the weight of the counterweight block is 3KG. Under the above ratio, the force applied by the powder pressing rod 4 to the powder hammer 6 is 12KG, which effectively ensures the density and uniformity of the coffee powder, and ensures the stability of the taste and flavor of the coffee obtained by subsequent extraction.

[0029] The specific solution also includes a mounting plate, on which a fixing frame 7 is provided, and the fixing frame 7 is provided with a bowl cavity for fixing the powder bowl 4; during the pressing process, the mounting plate and the fixing frame 7 cooperate with each other, so that the powder bowl 5 and the powder hammer 6 will not have relative displacement, thereby ensuring stability when pressing the powder.

[0030] In a further solution, the outer wall of the powder bowl 5 is further provided with a handle 51, and the fixing frame 7 is provided with a first notch 71 for avoiding the handle and a second notch 72 for avoiding the powder hammer; the handle 51 can help the user place the powder bowl 5 on the fixing frame 7, and avoid the handle through the first notch 71, thereby enhancing the rationality of the structural coordination; in a more optimal solution, during the placement process, the first notch 71 is abutted against the handle 51, thereby further increasing the placement stability of the powder bowl 5, and ensuring that the powder pressing rod 4 will not move during the pressing process, resulting in uneven compaction density of the coffee powder.

[0031] In a further solution, the lever arm 2 is also provided with at least two limit plates 21, and an equal number of limit plates 21 are respectively placed at both ends of the counterweight 3 to limit the movement of the counterweight 3; it is not difficult to understand that a thread connected to the limit plate 21 can be set at the corresponding position of the lever arm 2, first one limit plate 21 is screwed into the desired position, and then the counterweight 3 is sleeved on the lever arm, and finally the other limit plate 21 is screwed into another expected position, so that the counterweight 3 can be clamped and fixed by the two limit plates 21, thereby limiting the movement of the counterweight 3 on the lever arm 2, causing the powder pressing rod 4 to change the extrusion pressure of the powder hammer 6.

[0032] In this embodiment, the powder pressing rod 4 is hinged to the lever arm rod 2, and the support rod 1 is hinged to the lever arm rod 2; the hinged connection enables convenient storage; on the other hand, the addition of a hinged solution allows the user to easily take out or press the powder hammer 6 and the powder bowl 5 during use.

[0033] The advantages of the utility model are:

[0034] 1) Through the coordination of the counterweight, the lever arm and the tamping rod, the tamping rod presses the tamper based on the mass of the counterweight to compress the powder holding space, ensuring that the tamping force of multiple tamping sequences is within the expected range, making the taste and flavor of the extracted coffee more uniform;

[0035] 2) The first notch abuts against the handle, further increasing the placement stability of the powder bowl and ensuring that the powder pressing rod does not move during the pressing process, resulting in uneven compaction density of the coffee powder.

[0036] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
