Description

[Technical Field]

[0001] This utility model relates to a needle-type powder applicator. [Background Technology]

[0002] Freshly ground coffee has a richer and more aromatic flavor, which consumers prefer. In the coffee-making process, coffee beans are ground into powder using a grinder and then poured into a coffee caddy. The coffee powder produced by the grinder is not uniform, so a coffee tamper is needed to stir the coffee powder in the caddy to make it fluffy. Then, a coffee tamper is used to smooth and compact the surface of the coffee powder before it is extracted in the coffee machine. To achieve the functions of distributing and tamping the coffee powder, two products are currently available on the market: a coffee tamper and a tamper hammer. The structure of the tamper hammer is similar to that of the one with patent number 202421264133.5, named "Impact-type Coffee Tamper Hammer". It uses an impact hammer to impact the coffee caddy, thereby compacting the coffee powder. It has a strong impact force and a good compaction effect, but it cannot perform the function of distributing the coffee powder. An additional device is needed for distributing the coffee powder.

Detailed Implementation Methods

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 6As shown, a tamping hammer with a powder dispensing function includes a connecting handle 1, which is a hollow cylinder with openings at both the top and bottom. The lower end of the connecting handle 1 is provided with a tamping block 2 for tamping the powder. The tamping block 2 is provided with a positioning block 3 that can slide up and down relative to the tamping block 2 and press against the powder cup. At this time, the tamping block 2 can rotate and move up and down. When tamping the powder, the hand holds the connecting handle 1, which is a hollow connecting cylinder. Under the action of gravity, the positioning block 3 slides downward relative to the tamping block 2. When the positioning block 3 presses against the powder cup, after releasing the hand, the tamping block 2 and the connecting handle 1 slide downward relative to the positioning block 3 under the action of gravity. The tamping block 2 presses on the coffee powder, realizing one pre-tamping. The bottom of the tamping block 2 has a tamping end face 21 that can press the coffee powder in the coffee cup. The tamping end face 21 has a protrusion 22 that can scrape the coffee powder evenly when the tamping block 2 rotates relative to the positioning block 3. When the protrusion 22 rotates, it scrapes or evens the coffee powder at the top. In this case, there are multiple protrusions 22, and the height of the multiple protrusions 22 gradually increases in a clockwise or counterclockwise direction. The highest height of the protrusion 22 is preferably no more than 3mm. The upper end of the connecting handle 1 has a handle assembly 5 that can move up and down relative to the connecting handle 1. The handle assembly 5 has an impact device 6 that can generate an impact force on the tamping block 2 when triggered by the handle assembly 5. The impact device 6 has an elastic element to prevent the handle assembly 5 from sliding down under the action of gravity.

[0023] To facilitate better tamping, the tamping end face 21 has multiple concentric grooves 23. The openings of the grooves 23 are funnel-shaped, making it less likely for coffee powder to get trapped inside after tamping. The included angle α between the two sides of the opening of the groove 23 is 60°±20°, with the optimal angle being 60°. The depths of the multiple grooves 23 are the same, ensuring that the height of the coffee powder on the top surface is consistent after tamping.

[0024] The powder pressing block 2 includes a central column 24 that can be impacted by the impact device 6. The upper end of the central column 24 extends into the connecting handle 1. The central column 24 is a counterweight. An upper powder pressing block 25 and a lower powder pressing block 26 are detachably connected to the central column 24 and are arranged relatively apart. The upper powder pressing block 25 and the lower powder pressing block 26 are respectively threaded to the central column 24. The upper powder pressing block 25 is threaded to the lower end of the connecting handle 1. The upper powder pressing block 25 and the lower powder pressing block 26 are at least relatively separated at the edges. The relatively separated space is used to install the positioning block 3. The powder pressing end face 21 is located at the lower end of the lower powder pressing block 26. The positioning block 3 is sleeved with the upper powder pressing block 25 and the lower powder pressing block 26. The upper powder pressing block 25 is provided with an upper positioning device 27 that positions the positioning block 3 when it moves upward. The lower powder pressing block 26 is provided with a lower positioning device 28 that positions the positioning block 3 when it moves downward. The upper powder pressing block 25, the lower powder pressing block 26, and the positioning block 3 are all annular bodies. The positioning block 3 can move up and down between the upper positioning device 27 and the lower positioning device 28. The positioning block 3 can rotate relative to the upper powder pressing block 25 and the lower powder pressing block 26. The upper positioning device 27 is a first groove with an opening facing downward for the upper end of the positioning block 3 to extend into, and the lower positioning device 28 is a second groove with an opening facing upward for the lower end of the positioning block 3 to extend into. The lower end of the positioning block 3 is located on the outside of the pressing powder block 26 and is used to press against the positioning end face 31 on the powder cup. A sealing ring 4 is provided between the lower end of the positioning block 3 and the outer wall of the pressing powder block 26 to prevent coffee powder from entering the pressing powder block 26.

[0025] The handle assembly 5 includes an outer sleeve 51 and an inner sleeve 52 located inside the outer sleeve 51 and extending to the top of the powder pressing block 2. The inner sleeve 52 is a hollow cylinder with openings at both the top and bottom. The outer sleeve 51 and the inner sleeve 52 are hollow annular tubes. The inner sleeve 52 and the outer sleeve 51 are spaced apart to form a cavity 53 with an opening at the bottom. The upper end of the outer sleeve 51 is provided with a cover 56. The cover 56 is provided with a connecting edge 57 that extends into the upper end of the cavity 53 and is threaded to the outer sleeve 51 and the inner sleeve 52. The connecting edge 57 is an annular edge with threads on both the inner and outer sides, which are threaded to the outer sleeve 51 and the inner sleeve 52 respectively. The outer sleeve 51 is covered with a wooden handle sleeve 58. The connecting handle 1 is fitted outside the inner sleeve 52 and the upper end of the connecting handle 1 is inserted into the cavity 53 from the lower opening. The inner sleeve 52 extends into the connecting handle 1. The impact device 6 is located inside the inner sleeve 52. The outer wall of the inner sleeve 52 is provided with a first anti-rotation plane 59, and the connecting handle 1 is provided with a second anti-rotation plane 11 that can abut against the first anti-rotation plane 59. In this way, the inner sleeve 52 can move downward relative to the inner sleeve 52. A positioning boss is provided in the connecting handle 1 to prevent the inner sleeve 52 from being pulled upward.

[0026] The inner wall of the inner sleeve 52 is provided with a supporting protrusion ring 54. The impact device 6 includes an impact hammer 61 located inside the inner sleeve 52, with one end able to pass through the supporting protrusion ring 54 and extend above the powder pressing block 2. The central column 24 is located directly below the impact hammer 61. The impact hammer 61 is provided with a positioning protrusion ring 62 that can press against the upper end of the supporting protrusion ring 54. The end face of the positioning protrusion ring 62 is inclined to the end face of the supporting protrusion ring 54 to tilt the impact hammer 61. The lower end face of the positioning protrusion ring 62 is thinner on one side and the other side is thinner. After pressing against the supporting protrusion ring 54, the axis of the supporting protrusion ring 54 is... The line is inclined, not vertical. The cover 56 has a vertically extending guide sleeve 55 above the impact hammer 61, allowing the upper end of the impact hammer 61 to be inserted. The groove inside the guide sleeve 55 is vertical, guiding the upper end of the impact hammer 61 vertically after insertion into the guide sleeve 55. The powder pressing block 2 has a positioning edge 29 below the impact hammer 61, which can hold the lower end of the impact hammer 61 in place when it is tilted. This prevents the impact hammer 61 from moving downwards when tilted. The inner sleeve 52 has a lower end that presses against the positioning protrusion 62, and when the handle assembly 5 moves downwards... An energy storage spring 63 that can be compressed has its upper end pressing against the top of the inner sleeve 52 and its lower end pressing against the positioning protrusion ring 62. The powder pressing block 2 has an impact groove 30 that allows the lower end of the impact hammer 61 to insert when the handle assembly 5 moves downwards. The impact groove 30 is directly opposite the guide sleeve 55, with their axes coinciding. The positioning edge 29 is located at the upper edge of the impact groove 30. The impact groove 30 is located at the upper end of the central column 24. After the handle assembly 5 moves downwards and compresses the energy storage spring 63, the upper end of the impact hammer 61 inserts into the guide sleeve 55, causing the impact hammer 61 to... When vertical, the lower end of the impact hammer 61 deviates from the positioning edge 29, meaning the positioning edge 29 no longer presses against the lower end of the impact hammer 61. The lower end of the impact hammer 61 slides into the guide sleeve 55, and under the action of the energy storage spring 63, the impact hammer 61 plunges into the impact groove 30. A return spring 64 is provided between the lower end of the positioning protrusion ring 62 and the powder pressing block 2, capable of pressing the inner sleeve 52 upwards. After release, the return spring 64 presses the inner sleeve 52 upwards, and the positioning edge 29 also returns to its upward position. The positioning edge 29 then presses against the positioning protrusion ring 62 again, causing the impact hammer 61 to tilt again. The impact device can also be of other structural forms, such as those disclosed in patents with patent numbers 202421249497.6, 202420155363.1, and 202321597649.7, as long as it can generate an impact force on the powder pressing block.
