[0002] Coffee is a beverage made from roasted coffee beans (the seeds of the coffee plant); a coffee machine is an appliance that can brew coffee.

[0003] Existing coffee machines have automatic tamping components. For example, in the existing patent document "CN222955250U A Semi-Automatic Coffee Machine", the tamping and brewing mechanism consists of a main screw, a toothed disc, a threaded sleeve, a tamping head, and multiple microswitches. When the worm gear rotates under the drive of an external motor, it drives the screw part of the main screw to rotate through the toothed disc, and further drives the threaded sleeve and the tamping head to move up and down along the screw part through the threaded engagement to achieve tamping.

[0004] The existing tamping head in the above-mentioned technology is driven by multiple components such as a motor, worm gear, toothed disc, screw and threaded sleeve. Its overall structure for tamping is complex, which leads to a high price of the whole machine. Furthermore, after the coffee powder is ground, due to static electricity, the coffee powder will splash and adhere. Utility Model Content

[0009] Preferably, the linkage structure includes a crank; one end of the crank is hinged to a connecting rod, and the bottom end of the connecting rod is connected to the powder pressing head via a pin; a rotating shaft is installed at the end of the crank away from the connecting rod, and a top frame is fixedly installed on the top of the cylinder, with the rotating shaft rotatably connected to the top frame.

Detailed Implementation

[0028] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0029] like Figures 1-9 As shown, a semi-automatic coffee machine with a manual tamping mechanism includes a coffee machine body 1; and further includes: The coffee grinding mechanism 2 is located at the top of the coffee machine body 1; The tamping mechanism 3 is connected to the grinding mechanism 2 via a transfer device. The transfer device is used to transport the coffee powder ground in the grinding mechanism 2 to the tamping mechanism 3. The transfer device and the grinding mechanism 2 can adopt the transfer device and grinding mechanism in the existing technology "CN222955250U A Semi-automatic Coffee Machine".

[0030] The powder pressing mechanism 3 includes a powder pressing head 306, which is connected to a control handle 4 via a linkage structure. When the control handle 4 is turned, the powder pressing head 306 is moved up and down via the linkage structure, thus realizing a manual powder pressing design and increasing the controllability of operation.

[0031] A negative ion generator 5 is disposed inside the coffee machine body 1; the portion connecting the tamping mechanism 3 and the grinding mechanism 2 is also disposed inside the coffee machine body 1. During grinding, the negative ion generator 5 generates negative ions to eliminate static electricity and prevent coffee powder from splashing and adhering due to static electricity. Specifically, the negative ion generator 5 is fixedly installed above the cylinder 301 of the tamping mechanism 3.

[0032] like Figure 3 As shown, as a specific technical solution, the tamping mechanism 3 further includes a cylinder 301; the cylinder 301 is fixedly installed on the coffee machine body 1, the top of the cylinder 301 is located inside the upper part of the coffee machine body 1, and the bottom of the cylinder 301 extends out from inside the upper part of the coffee machine body 1.

[0033] like Figures 6-8 As shown, as a specific technical solution, the tamping head 306 is vertically slidably installed inside the cylinder 301. A mesh cover 6 is fixedly installed inside the cylinder 301, and the mesh cover 6 is located below the tamping head 306. Coffee powder is conveyed into the tamping mechanism 3 and collected by the mesh cover 6; then, by driving the tamping head 306 to move downward, the coffee powder above the mesh cover 6 is pressed down, thus achieving tamping.

[0034] like Figures 6-7 As shown, as a specific technical solution, the linkage structure includes a crank 303; one end of the crank 303 is hinged to a connecting rod 304, and the bottom end of the connecting rod 304 is connected to the powder pressing head 306 through a pin 307; a rotating shaft 305 is installed at the end of the crank 303 away from the connecting rod 304, and a top frame 302 is fixedly installed on the top of the cylinder 301, and the rotating shaft 305 is rotatably connected to the top frame 302.

[0035] One end of the rotating shaft 305 extends to the outside of the coffee machine body 1, and the end of the rotating shaft 305 located on the outside of the coffee machine body 1 is connected to the control handle 4.

[0036] By rotating the control handle 4 clockwise, the crank 303 and connecting rod 304 drive the powder pressing head 306 to move downwards to press the powder.

[0037] After tamping, the operating handle 4 is rotated counterclockwise, which drives the tamping head 306 upward via the crank 303 and connecting rod 304. The tamping head 306 moves away from the mesh cover 6, and a sufficient space is formed between the tamping head 306 and the mesh cover 6 to accommodate the coffee powder.

[0038] like Figure 6 , Figure 7 as well as Figure 9 As shown, as a specific technical solution, the top two sides of the powder pressing head 306 are provided with nests 3061, and springs 308 are embedded in the nests 3061. The bottom end of the connecting rod 304 is rotatably mounted with a pin 307. The two side walls of the powder pressing head 306 are provided with movable insertion holes 3063 that communicate with the top side of the nests 3061. The two ends of the pin 307 are respectively inserted into the two movable insertion holes 3063, and the top end of the spring 308 abuts against the pin 307.

[0039] like Figure 7 as well as Figure 9 As shown, as a specific technical solution, the side of the nest 3061 away from the movable insertion hole 3063 is provided with a movable groove 3062, and the pin 307 passes through the movable groove 3062.

[0040] The length of the movable socket 3063 is greater than the diameter of the pin 307; the end of the pin 307 is slidably installed into the movable socket 3063 along the vertical direction.

[0041] During the downward movement of the driving powder pressing head 306, when the powder pressing head 306 is not in contact with the powder, the pin 307 is located on the top side of the movable insertion hole 3063. There is a distance between the pin 307 and the bottom side wall of the movable insertion hole 3063, and there is also a distance between the pin 307 and the bottom side wall of the movable groove 3062.

[0042] When the tamping head 306 contacts the coffee powder, the tamping head 306 is obstructed and cannot move further downwards, while the pin 307 continues to move downwards (due to the design that there is a distance between the pin 307 and the bottom side wall of the movable insertion hole 3063, and also a distance between the pin 307 and the bottom side wall of the movable groove 3062, the pin 307 can continue to move downwards a certain distance relative to the tamping head 306), thus compressing the spring 308. The compression force of the spring 308 acts on the tamping head 306, and then acts on the coffee powder through the tamping head 306, achieving a compaction effect.

[0043] The design of the spring 308 ensures effective compression of the coffee powder.

[0044] A microswitch (not shown in the figure) is fixedly installed at the top port of the cylinder 301. After tamping, when the tamping head 306 moves upward and returns to its initial state, the microswitch is triggered. The microswitch is connected to the control system inside the coffee machine body 1. The control system causes the indicator light to illuminate or the speaker to emit a warning sound, reminding the tamping head 306 to move upward to the highest position.

[0045] like Figure 9 As shown, as a specific technical solution, the powder pressing head 306 is externally fixed with a sealing ring, and the sealing ring is tightly fitted to the inner wall of the cylinder 301.

[0046] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
