It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0037] like Figures 1 to 4 As shown, this embodiment provides a coffee capsule machine with an arc-shaped powder pressing device, which is characterized by comprising:

[0038] Body 1;

[0039] a bean grinding device, arranged on the machine body 1, comprising a bean grinding tank 2, the bean grinding tank 2 being used for adding coffee beans, a grinding assembly being installed at the bottom of the bean grinding tank 2 for grinding the coffee beans into coffee powder; and,

[0040] The arc-shaped powder pressing device is arranged in the machine body 1 and is arranged in parallel with the bean grinding device. The arc-shaped powder pressing device includes an arc-shaped arc-shaped powder pressing channel 3 arranged from bottom to top, a powder hammer 4 arranged in the arc-shaped powder pressing channel 3 for sliding up and down, and a driving mechanism for driving the powder hammer 4 to slide up and down along the arc-shaped powder pressing channel 3. Specifically, when the powder pressing action is performed, the driving mechanism drives the powder hammer 4 to slide downward from the reset position located on the upper side to the powder pressing position located on the lower side along the arc-shaped powder pressing channel 3; when the powder pressing is completed, the driving mechanism drives the powder hammer 4 to slide upward from the powder pressing position to the reset position along the arc-shaped powder pressing channel 3.

[0041] The arc-shaped powder pressing channel 3 is fixedly arranged on a fixed seat in the machine body 1, and the arc-shaped powder pressing channel 3 includes a driving end, a transition section and a powder outlet end from top to bottom. The powder outlet end is located at the lower side of the bean grinding tank 2, and the transition section bypasses the bean grinding tank 2 so that the driving end is not interfered by the shape of the bean grinding tank 2. Specifically, when the driving mechanism drives the powder hammer 4 to slide up and down along the arc-shaped powder pressing channel 3, the bean grinding tank 2 will not interfere with the movement path of the powder hammer 4. The powder outlet end is provided with a powder outlet 32, and the powder outlet 32 ​​is used to dock with the capsule box.

[0042] In some specific embodiments, Figure 1 and Figure 2 As shown, the arc-shaped powder pressing channel 3 is gradually arched upward from left to right or from right to left in an arc shape from the lower front side of the bean grinding tank 2. The bean grinding tank 2 includes a cylindrical tank body located at the upper part and a conical tank body located at the lower side of the cylindrical tank body and the diameter of which gradually decreases from top to bottom. The cylindrical tank body and the conical tank body are preferably integrally formed; in order to facilitate the capsule box to receive powder, the powder outlet is located at the lower front side of the conical tank body, and the transition section bypasses the conical tank body from bottom to top and from right to left from the front side of the conical tank body; specifically, the powder outlet is arranged at the lower front side of the conical tank body, so that the lateral spacing between the two is smaller, thereby making the internal structure layout of the machine body 1 more compact, and the volume of the entire coffee capsule machine is further reduced. When the transition section bypasses the conical tank body, not only will the bean grinding tank 2 not interfere with the powder hammer 4, but the powder pressing stroke will also increase accordingly, which can meet the needs of powder pressing.

[0043] The above embodiment can also be arranged such that the powder outlet end is located below the front side of the conical tank body, and the transition section goes around the conical tank body from the front side of the conical tank body from bottom to top and from left to right.

[0044] In some specific embodiments, Figures 2 to 4 As shown, a mounting seat 33 is provided on the side wall of the arc-shaped powder pressing channel 3, and the driving mechanism is arranged on the mounting seat 33. A specific structure of the driving mechanism is that the driving mechanism includes a powder hammer motor 5 and a transmission assembly, and the transmission assembly includes a gear set and an arc-shaped rack 41. The output shaft of the powder hammer motor 5 is connected to the input end of the gear set, and the output end of the gear set is connected to the arc-shaped rack 41, specifically a meshing transmission, and the arc-shaped rack 41 is slidably arranged in the arc-shaped powder pressing channel 3 and the lower end of the arc-shaped rack 41 is connected to the powder hammer 4. The arc-shaped rack 41 and the powder hammer 4 can be arranged as an integral molding, or the two are fixedly connected. When the powder hammer motor 5 drives the gear set to rotate, the gear set drives the arc-shaped rack 41 and the powder hammer 4 to slide up and down by meshing with the arc-shaped rack 41 to perform a powder pressing action or a reset action.

[0045] The gear set includes a first gear 331 and a second gear 332 . The output shaft of the hammer motor 5 is connected to the first gear 331 , and the second gear 332 is meshed with both the first gear 331 and the arc-shaped rack 41 .

[0046] In some specific embodiments, Figures 2 to 4 As shown, in order to make the layout inside the machine body 1 more compact, the meshing teeth of the arc-shaped rack 41 are located inside the arc-shaped rack 41. Therefore, the mounting seat 33 and the driving mechanism can be arranged in the inner space surrounded by the arc-shaped powder pressing channel 3. In order to facilitate the meshing transmission between the second gear 332 and the arc-shaped rack 41, a clearance groove 31 is provided on the side wall of the arc-shaped powder pressing channel 3, and the second gear 332 passes through the clearance groove 31 and meshes with the arc-shaped rack 41.

[0047] In some specific embodiments, Figure 4 As shown, a sealing ring 6 is provided between the powder hammer 4 and the inner wall of the arc-shaped powder pressing channel 3. The sealing ring 6 can play a sealing role to prevent coffee powder from entering the machine body 1 from the arc-shaped powder pressing channel 3. An arc-shaped guide groove 34 is also provided on the side wall of the arc-shaped powder pressing channel 3, and a guide block 411 is provided on the arc-shaped rack 41. The guide block 411 is located in the arc-shaped guide groove 34, thereby limiting the upper end position and the lower end position of the arc-shaped rack 41.

[0048] In some specific embodiments, the bean grinding device also includes a grinding assembly arranged in the bean grinding tank 2, and the grinding assembly specifically includes a grinding knife and a grinding motor that drives the grinding knife to grind powder. A lower powder channel 21 is provided between the grinding assembly and the arc-shaped powder pressing channel 3. The coffee powder ground by the grinding assembly flows into the arc-shaped powder pressing channel 3 through the lower powder channel 21, and then falls into the capsule box at the lower end of the arc-shaped powder pressing channel 3. After that, the driving mechanism can be directly started to drive the powder hammer 4 to press the coffee powder in the capsule box, so that the process continuity is better.

[0049] Working principle description:

[0050] The arc-shaped powder pressing channel 3 is curved upward from the lower side of the conical tank body and bypasses the conical tank body to the left, avoiding directly vertically supporting the conical tank body, so that the lateral distance between the arc-shaped powder pressing channel 3 and the conical tank body is further reduced, thereby reducing the volume of the entire coffee capsule machine. When performing the powder pressing action, the powder hammer motor 5 drives the arc-shaped rack 41 to slide downward through the gear set, thereby driving the powder hammer 4 to slide downward along the arc-shaped powder pressing channel 3 to press the powder.

[0051] The present invention is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shapes or structures, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
