[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present utility model provides a constant-force secondary pressurizing powder pressing hammer, which has the following

[0014] beneficial effects:

[0015] 1. The constant-force secondary pressurizing powder pressing hammer is composed of a spring, an impact hammer, a first sliding structure and a second sliding structure. By pressing the handle to a certain distance, the fixing pin is pushed to slide downwards, and the impact hammer is pushed to impact the powder pressing base to generate a downward pressure. At the same time, when preloading the spring, a downward pressure is also transmitted to the powder pressing base. This results in the superposition of two forces in sequence to compact the coffee powder, achieving the purpose of leveraging the pressure generated by the spring elasticity and the impact force of the impact hammer. The pressure can also be adjusted by adjusting the screw, making the powder pressing force change, which is convenient for use.

[0016] 2. The constant-force secondary pressurizing powder pressing hammer uses the combination of a horizontal plate and a vertical spring to increase the powder pressing force, reducing the smaller force output by the human body. It is applicable to a wider range of people. The horizontal plate is fixed and balanced, and the user can easily and evenly flatten the coffee powder without having to adjust the powder pressing direction back and forth, thus achieving the purpose of uniform compaction.

[0023] A handle 108 is installed at the top of the upper hammer body 107. A pressing plate 110 is connected to the bottom of the handle 108. A preloading spring 116 is installed at the bottom of the pressing plate 110. An adjusting screw 109 is connected to the outside of the preloading spring 116. A second sliding structure 103 is connected to the outside of the adjusting screw 109. A second sliding hole 1031 is formed in the outside of the second sliding structure 103. A telescopic spring 114 is installed inside the second sliding structure 103. The top of the outside of the second sliding structure 103 is connected to the inner top of the upper hammer body 107. The outside of the second sliding structure 103 is connected to the inside of the middle hammer body 104. The bottom of the preloading spring 116 is connected to a striking hammer 111. A first sliding structure 102 is installed on the outside of the striking hammer 111. A first sliding hole 1021 is formed in the outside of the first sliding structure 102. A fixing pin 112 is installed inside the first sliding structure 102. The force of the preloading spring 116 can be adjusted according to different needs. Then, the adjusting screw 109 is adjusted to change the force of powder pressing. When the adjusting screw 109 is tightened downward, the preloading spring 116 is stressed, and the pressure will increase when the powder pressing base 101 presses the powder, and vice versa, the pressure will decrease.

[0024] A horizontal plate 105 is installed at the inner bottom of the middle hammer body 104. The outside of the horizontal plate 105 is connected to a vertical spring 113. The inside of the horizontal plate 105 is connected to the outside of the first sliding structure 102. The vertical spring 113 is arranged inside the first sliding structure 102. The fixing pin 112 is connected through the top inner side of the striking hammer 111. The top of the outside of the first sliding structure 102 is connected to the inner bottom of the second sliding structure 103. The diameter of the first sliding structure 102 is smaller than that of the second sliding structure 103. The top of the first sliding hole 1021 is correspondingly connected to the bottom side of the second sliding hole 1031. A horizontal ring 115 and a powder pressing base 101 are installed at the bottom of the first sliding structure 102. The horizontal ring 115 is arranged inside the top of the powder pressing base 101. Through the cooperation of the horizontal plate 105 and the vertical spring 113, by means of the mechanical force of the internal structure, the powder pressing force is increased, the force output by the human body is reduced, and the applicable population is wider. The horizontal plate 105 is fixed and balanced. The user can easily and evenly flatten the coffee powder without adjusting the powder pressing direction back and forth, so as to achieve the purpose of uniform compaction.

[0025] The inside of the lower hammer body 106 is connected to the outside of the first sliding structure 102.

[0026] In use, the user holds the middle hammer body 104 of the tamper, moves the tamper base 101 to the top of the coffee powder to be compacted, initially flattens the coffee powder, and then presses the handle 108. The handle 108 moves downward to press the pressing plate 110. The pre-compression spring 116 at the bottom of the pressing plate 110 is compressed, and the impact hammer 111 drives the fixing pin 112 to move downward. The fixing pin 112 drives the second sliding structure 103 to move from the second sliding hole 1031 to the first sliding hole 1021. The pre-compression spring 116 instantaneously rebounds to push the impact hammer 111 to strike the tamper base 101. The tamper base 101 generates a downward pressure to compact the coffee powder. At the same time, the pre-compression spring 116 also transmits a downward pressure to the tamper base 101, achieving the superposition of two different forces in sequence to compact the coffee powder. When the force on the handle 108 is withdrawn, the pre-compression spring 116 contracts, and the impact hammer 111 drives the fixing pin 112 to rise. To repeat the operation, it is only necessary to press the handle 108 again.
