Description

Technical Field

[0001] The utility model relates to the technical field of coffee utensils, and particularly relates to a coffee tamper with high stability. Background Art

[0002] Pressing the powder is a very important step in the process of making espresso. By pressing the powder, a flat horizontal surface is formed to facilitate extraction. Usually, when extracting coffee, the coffee powder needs to be pressed into a cake shape and placed in a powder bowl, and the density of the powder cake is changed by different pressures to change the taste of the coffee after extraction. Only by ensuring that the surface of the powder cake is horizontal and the density of the powder cake is uniform can a cup of coffee with a good taste be extracted. However, when the existing coffee tampers are in use, the handle is prone to swing and shake, the stability during pressing is insufficient, and noise will also be generated, affecting the user experience.

A first spring is sleeved outside the crankshaft, and the first spring abuts against the inner sides of the handle and the bottom cover respectively. The crankshaft is slidably connected to the pressing rod through a locking pin. A second spring is arranged between the crankshaft and the pressing rod. The bottom of the pressing rod passes through the positioning sleeve and is threadedly connected to the powder pressing head.

[0006] Preferably, an external thread is provided on the outer peripheral wall of the upper end of the handle, and a handle head is sleeved on the upper end of the handle.

[0007] Preferably, an external thread is provided on the outer peripheral wall of the upper end of the crankshaft, and an internal thread adapted to the external thread is provided on the inner side of the handle.

[0008] Preferably, two symmetrically arranged locking pin sliding through holes are opened on the outer side of the crankshaft. A locking pin installation through hole adapted to the locking pin is opened on the side surface of the upper end of the pressing rod. The locking pin passes through the locking pin installation through hole and abuts against the inner side of the locking pin sliding through hole.

[0009] Preferably, two symmetrically arranged disassembly and assembly through holes are provided on the outer side of the lower end of the pressing rod. The second spring is located inside the crankshaft, and the second spring abuts against the crankshaft and the pressing rod respectively.

[0010] Preferably, a threaded groove is provided at the upper end of the powder pressing head, and the bottom of the pressing rod is inserted into the threaded groove.

[0011] Adopting the above technical solution, a high-stability coffee powder press provided by the present utility model has the following beneficial effects: The upper end of the crankshaft in the high-stability coffee powder press is threadedly connected to the inner side of the handle, the bottom of the positioning sleeve is threadedly connected to the inner side of the bottom cover. A first spring is sleeved on the outer side of the crankshaft, and the first spring abuts against the inner sides of the handle and the bottom cover respectively. The crankshaft is slidably connected to the pressing rod through a locking pin. A second spring is arranged between the crankshaft and the pressing rod. The bottom of the pressing rod passes through the positioning sleeve and is threadedly connected to the powder pressing head. By providing the positioning sleeve to fix and place the pressing rod, the concentricity of internal components such as the crankshaft and the pressing rod is increased, making it more reliable, avoiding the phenomenon that the handle is prone to swaying during use, improving the stability during downward pressing, not generating noise, having a good sound insulation effect, and a good user experience.
