Description

Technical Field

[0001] The utility model relates to the technical field of coffee making equipment, in particular to an impact-type coffee powder pressing hammer. Background Art

[0002] The tamper or tamping hammer is one of the most commonly used tools in Italian coffee. Its main purpose is to flatten and compact the coffee powder in the handle to form a flat horizontal surface, so that hot water can be better extracted through the coffee powder, and the coffee powder can withstand the huge pressure generated by the coffee machine during extraction, so as not to be dispersed and affect the extraction quality. In the process of compacting the coffee powder filled in the coffee powder bowl with the coffee tamping hammer, the coffee tamping hammer is placed on the upper part of the coffee powder bowl, and after applying pressure to the tamping hammer, the coffee tamping hammer uses the spring installed inside to apply pressure to the punching hammer. After the pressure accumulates energy on the punching hammer, the punching hammer applies instantaneous pressure to the load-bearing block. At the same time, when the spring applies a certain pressure to the punching hammer, the punching hammer can perform a punching process downward. However, due to the different thickness of the coffee powder during the process of the spring applying pressure to the punching hammer, the coffee powder will not be completely compacted, resulting in the punching hammer not compacting the coffee powder. For this reason, we propose an impact-type coffee tamping hammer. Utility Model Content

[0003] In view of the shortcomings of the existing impact-type coffee powder tamping hammer, the utility model provides an impact-type coffee powder tamping hammer, which has the advantages of being kept in an inclined state by the impact hammer, and after the lower end of the impact hammer is clamped on the upper end of the load-bearing block, a third spring applies pressure to the impact hammer. After applying a specific pressure, the impact hammer contacts the middle step of the outer sleeve, and the middle step of the outer sleeve drives the impact hammer to a stable state. At the same time, the impact hammer punches the load-bearing block, thereby ensuring the stability of the impact hammer during punching, thereby solving the problems raised in the above-mentioned background technology.

[0004] The utility model provides the following technical scheme: an impact type coffee powder pressing hammer, comprising an outer sleeve, a telescopic sleeve movably sleeved inside the outer sleeve, a first spring sleeved outside the telescopic sleeve, an inner threaded connection of a base at the lower end of the outer sleeve, a powder tray threaded inside the telescopic sleeve, a load-bearing block threadedly connected to a outer sleeve at the middle end of the powder tray, an outer sleeve movably sleeved at the upper end of the telescopic sleeve, a limiting plate fixedly connected to the middle of the outer sleeve, a second spring installed at the lower end of the limiting plate, an upper sealing sleeve connected to the outer threaded connection of the upper end of the outer sleeve, an outer sleeve middle step placed at the top of the outer sleeve, a third spring installed at the lower end of the outer sleeve middle step, an impact hammer installed at the lower end of the outer sleeve middle step, the outer sleeve middle step can correct the position of the impact hammer, the thicknesses of the two ends of the mounting flange in the middle of the impact hammer are different and are tilted in a natural state, and a handle is sleeved outside the upper sealing sleeve.

[0005] Preferably, the powder tray is arranged at the lower end of the base, and a circular groove with a gradually increasing diameter is formed at the lower end of the powder tray.

[0006] Preferably, a limit plate is installed on the inner side of the base, and the first spring is installed between the telescopic sleeve and the limit plate installed on the inner side of the base.

[0007] Preferably, the lower end of the outer sleeve is arranged between the telescopic sleeve and the load-bearing block, and the lower end of the outer sleeve is clamped inside the upper end of the telescopic sleeve.

[0008] Preferably, the second spring is installed between the load-bearing block and the limit plate, and the third spring is installed on the middle step of the outer sleeve and the upper part of the limit sleeve installed on the outside of the impact hammer.

[0009] Preferably, a flange is installed on the outside of the impact hammer, and one end of the flange is thicker than the other end.

[0010] Preferably, the lower end of the load-bearing block is provided with a groove having the same shape as the lower end of the impact hammer, the upper end of the impact hammer is in an arc shape, and a groove is provided inside the middle step of the outer sleeve.

[0011] Compared with the existing impact coffee powder hammer, the utility model has the following beneficial effects:

[0012] The impact-type coffee powder pressing hammer is skewed in a natural state due to the uneven thickness of the flange, so that it presses against the edge of the upper end of the load-bearing block. The impact hammer will always press against the load-bearing block when pressed downward, compressing the third spring above. The third spring stores energy for the impact hammer. At the same time, when the outer sleeve moves to the lowest point, the groove opened inside the middle step of the outer sleeve will contact the impact hammer. The middle step of the outer sleeve drives the position of the impact hammer to be corrected, thereby realizing the impact action, and the powder in the coffee powder bowl can be pressed more firmly.

[0026] See also Figure 6 A flange is installed on the outside of the impact hammer 13, and one end of the flange is thicker than the other end. A flange is installed on the outside of the impact hammer 13, and one end of the flange is thicker than the other end. When pressure is applied to the handle 14, the flange installed on the outside of the impact hammer 13 is pushed to contact the limit plate 8 under the elastic action of the third spring 12. At the same time, due to the different thickness of the flange, the lower end of the impact hammer 13 remains inclined to one end.

[0027] Please refer to the figure. The lower end of the load-bearing block 6 is equipped with a groove of the same shape as the lower end of the impact hammer 13. The upper end of the impact hammer 13 is arc-shaped. At the same time, a groove is opened inside the middle step 11 of the outer sleeve. By applying pressure to the handle 14, the impact hammer 13 is driven to move downward in an inclined state. At the same time, the lower end of the impact hammer 13 contacts the upper end of the load-bearing block 6. When pressure is continuously applied, the third spring 12 stores energy for the impact hammer 13. At the same time, when the upper end of the impact hammer 13 contacts the middle step 11 of the outer sleeve, the top end of the impact hammer 13 is an arc surface, that is, the upper end of the impact hammer 13 moves along the trajectory inside the middle step 11 of the outer sleeve. The middle step 11 of the outer sleeve corrects the position of the impact hammer 13, and the impact hammer 13 is pushed downward by the elastic force of the third spring 12. After the lower end of the impact hammer 13 impacts the load-bearing block 6, the impact hammer 13 impacts the position of the load-bearing block 6.

[0028] Working principle: when in use, place the base 4 on the powder in the coffee powder bowl, and apply pressure to the handle 14. The handle 14 pushes the outer sleeve 7 to move downward, and at the same time, the powder tray 5 is forced to move downward under the action of the elastic force of the first spring 3. After the powder tray 5 has initially compacted the coffee powder placed on the coffee powder bowl, the bottom of the impact hammer 13 is pressed on the upper part of the load-bearing block 6 in an inclined state, and the handle 14 continues to press downward, and the third spring 12 applies pressure to the impact hammer 13 to store energy for the impact hammer 13. When the middle step 11 of the outer sleeve contacts the top of the impact hammer 13, the groove opened inside the middle step 11 of the outer sleeve pulls the top of the impact hammer 13, that is, the middle step 11 of the outer sleeve corrects the position of the impact hammer 13, and the lower end of the impact hammer 13 remains aligned with the groove opened inside the load-bearing block 6. At the same time, the impact hammer 13 accumulates energy to move downward, and the impact hammer 13 punches the load-bearing block 6.
