Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, in particular to a grinding coffee machine. Background Art

[0002] When grinding coffee beans, the coarseness of the powder depends on the cooking method. The shorter the cooking time, the finer the ground powder should be; the longer the cooking time, the coarser the ground powder should be, because the extraction of water-soluble substances in coffee powder has its ideal time. If the powder is very fine and the cooking is too long, it will cause over-extraction, and the coffee may be very bitter and lose its aroma; on the contrary, if the powder is very coarse and the cooking is too fast, it will cause insufficient extraction, and the coffee will be bland because there is no time to dissolve the water-soluble substances in the powder.

[0003] When grinding coffee beans, the existing coffee grinder will cause the temperature of the coffee powder to rise due to the high-speed friction movement, thus affecting the flavor and taste of the coffee. In addition, the existing grinding mechanism will leave residual coffee powder after grinding. The residual coffee oil and powder may mix with the fresh coffee beans, affecting the flavor of the coffee and resulting in a poor taste. In addition, the old oil may oxidize and produce odor, affecting the aroma of the new coffee. Summary of the invention

Since the output end of the driving component 4 is fixedly installed with the dynamic knife component 501, when the driving component 4 moves, it can drive the dynamic knife component 501 to move closer to or away from the static knife component 502, thereby facilitating the adjustment of the gap between them, and changing the grinding particle size of the coffee beans.

Since the multiple groups of first blades 5019 can rotate along with the first rotating belt 5015 and the second rotating belt 5026, their surfaces can contact the surface of the cleaning block 404, thereby cleaning the surface. The setting of the first cold runner 23 can cool the first blade 5019 moving out of the inner side of the first skeleton 5011 and the second skeleton 5022, so as to ensure that the low-temperature grinding is maintained when grinding the coffee beans, thereby reducing the impact on the flavor and taste of the coffee powder during grinding.

[0074] Embodiment three:

[0075] Based on Example 1, please refer to Figure 10-17 :

[0076] Further, for the above-mentioned dynamic knife assembly 501, the dynamic knife assembly 501 is a third skeleton 6, one side of the third skeleton 6 is fixedly installed with one end of the rotating rod 403, the outer surface of the third skeleton 6 is fixedly connected with a first limiting ring 7, the inner side of the first limiting ring 7 is rotatably provided with a third rotating roller 8, one end of the third rotating roller 8 is fixedly connected with a fourth motor 9, one end of the fourth motor 9 is fixedly installed with one side of the third skeleton 6, and one side of the third rotating roller 8 is provided with a third plug 10;

[0077] The outer surface of the third rotating roller 8 is transmission-connected with the third rotating belt 11, and a second mounting block 12 is fixedly mounted on the third rotating belt 11. A second paddle 13 is fixedly connected to one side of the second mounting block 12, and a second blade 14 is fixedly connected to the other side of the second mounting block 12. A third protrusion 15 is fixedly connected to the third skeleton 6, and one side of the third protrusion 15 is in contact with one side of the second paddle 13.

[0078] The first motor 402 is driven to rotate the rotating rod 403 fixedly installed at the output end. When the rotating rod 403 rotates, it can drive the third frame 6 fixedly installed at one end thereof to rotate. When the third frame 6 rotates, it can drive the first limiting ring 7 fixedly connected to its outer surface to rotate. When the first limiting ring 7 rotates, it can drive the third rotating roller 8 set on its inner side to perform circular motion. When the third rotating roller 8 performs circular motion, it can drive the third rotating belt 11 set on its surface transmission to perform circular motion. When the third rotating belt 11 performs circular motion, it can drive the second mounting block 12 fixedly installed inside thereof to perform circular motion. When the second mounting block 12 performs circular motion, it can drive the second knife body 14 fixedly connected to one side thereof to perform circular motion, so that it can cooperate with the static knife assembly 502 to grind the coffee beans. The fourth motor 9 is driven to rotate the third rotating roller 8 fixedly installed at the output end. When the third rotating belt 11 is rotated, it can drive the third rotating belt 11 arranged on its surface for transmission to operate. Since the second mounting block 12, the second paddle 13 and the second blade 14 are all provided with multiple groups and are multiple individuals, when the third rotating belt 11 is operated, it can drive the multiple second mounting blocks 12 fixedly installed therein to move. When the second mounting block 12 moves, it can drive the second paddle 13 fixedly connected on one side thereof to move. Since one side of the second paddle 13 is in contact with one side of the third protrusion 15, when the second paddle 13 moves, it can move on the surface of the third protrusion 15. When the second paddle 13 moves to the other side of the third protrusion 15, the friction between the second paddle 13 and the third protrusion 15 is reduced, so that it can drive the second mounting block 12 to shake. When the second mounting block 12 shakes, it can drive the second blade 14 fixedly connected on one side thereof to shake, so as to shake off the coffee powder on its surface.

[0079] Further, for the above-mentioned static knife assembly 502, the static knife assembly 502 is a fourth frame 16, one side of the fourth frame 16 is fixedly installed with the inside of the grinding barrel 203, the outer surface of the fourth frame 16 is fixedly connected with a second limiting ring 17, the inner side of the second limiting ring 17 is rotatably provided with a fourth rotating roller 18, one end of the fourth rotating roller 18 is fixedly connected with a fifth motor 19, one end of the fifth motor 19 is fixedly installed with one side of the fourth frame 16, and one side of the fourth rotating roller 18 is provided with a fourth plug 20;

[0080] The outer surface of the fourth rotating roller 18 is transmission-connected with the fourth rotating belt 21 , which is fixedly mounted on the outer surface of the second mounting block 12 . The interior of the fourth skeleton 16 is fixedly connected with the fourth protrusion 22 , and one side of the fourth protrusion 22 is in contact with one side of the second paddle 13 .

[0081] By starting the fifth motor 19 to drive the fourth rotating roller 18 fixedly connected to the output end to rotate, when the fourth rotating roller 18 rotates, it can drive the fourth rotating belt 21 set on its surface for transmission to operate. When the fourth rotating belt 21 operates, it can drive multiple second mounting blocks 12 fixedly installed therein to move. When the second mounting block 12 moves, it can drive the second paddle 13 fixedly connected to one side thereof to move. Since one side of the second paddle 13 is in contact with one side of the fourth protrusion 22, when the second paddle 13 moves, it can move on the surface of the fourth protrusion 22. When the second paddle 13 moves to the other side of the fourth protrusion 22, the friction between the second paddle 13 and the fourth protrusion 22 is reduced, so that it can drive the second mounting block 12 to shake. When the second mounting block 12 shakes, it can drive the second blade 14 fixedly connected to one side thereof to shake, so as to shake off the coffee powder on its surface.

[0082] Furthermore, for the third skeleton 6 , a second cold runner is provided on one side of the third skeleton 6 and the fourth skeleton 16 , and a second hot runner is provided on the other side of the third skeleton 6 and the fourth skeleton 16 .

[0083] The second hot runner and the second cold runner have the same functions and effects as the first hot runner 24 and the first cold runner 23, and can heat the second blade 14 entering the inner side of the third skeleton 6 and the fourth skeleton 16, so as to facilitate the flow and desorption of oil attached to the surface thereof, and can cool the second blade 14 moving out of the inner side of the third skeleton 6 and the fourth skeleton 16, so as to ensure that the coffee beans are ground at a low temperature, thereby reducing the impact on the flavor and taste of the coffee powder during grinding.

[0084] It should be noted that: the first mounting block 5017, the first paddle 5018, the first blade 5019, the first protrusion 5020, the second protrusion 5028, the second mounting block 12, the second paddle 13, the second blade 14, the third protrusion 15 and the fourth protrusion 22 are all provided in multiple groups in a circular array; and the first plug block 5014, the second plug block 5025, the third plug block 10 and the fourth plug block 20 are made of elastic material, and the first blade body 5019 and the second blade body 14 are inclined, so that they can pass through the inner sides of the first plug block 5014, the second plug block 5025, the third plug block 10 and the fourth plug block 20.

[0085] According to the above technical solution, 1. the dynamic knife assembly 501 is driven to rotate by starting the driving assembly 4, so that the dynamic knife assembly 501 is matched with the angle between the dynamic knife assembly 501 and the static knife assembly 502 to grind the coffee beans, and both the dynamic knife assembly 501 and the static knife assembly 502 can drive the blades to rotate cyclically, so that when the dynamic knife assembly 501 rotates and grinds, the time of friction and extrusion force on the blades can be shortened, the temperature rise of the blades can be slowed down, and the taste of the coffee powder can be avoided from being affected;

[0086] 2. By rotating the spiral rod 302, the spiral rod 302 moves up and down, so that it can drive the driving assembly 4 to move up and down. Since the output end of the driving assembly 4 is fixedly installed inside the dynamic knife assembly 501, when the driving assembly 4 moves, it can drive the dynamic knife assembly 501 to move closer to or away from the static knife assembly 502, so as to facilitate the adjustment of the gap between them, and change the grinding particle size of the coffee beans;

[0087] 3. By starting the third motor 5023 to drive the second rotating roller 5024 to rotate, the second rotating roller 5024 can drive the second rotating belt 5026 to operate, and the second rotating belt 5026 can cooperate with the second mounting groove 5027 to drive the first mounting block 5017 to operate. The first mounting block 5017 can drive the first paddle 5018 and one side of the second protrusion 5028 to move, and block the first paddle 5018. During the continuous movement of the first paddle 5018, it can be moved to the other side of the second protrusion 5028, and then its blocking force is released, so that it cooperates with the first mounting block 5017 to drive the first blade 5019 to shake, which can avoid the residue of coffee powder on the blade to a certain extent and improve the grease removal efficiency.

[0088] 4. Through the setting of the hot runner 24, the first blade body 5019 and the second blade body 14 entering the inner side of the first skeleton 5011, the second skeleton 5022, the third skeleton 6 and the fourth skeleton 16 can be heated, so as to facilitate the flow and desorption of grease attached to their surfaces, and make their surfaces contact with the surface of the cleaning block 404, so as to clean their surfaces. The setting of the cold runner 23 can cool the first blade body 5019 and the second blade body 14 moving out of the first skeleton 5011, the second skeleton 5022, the third skeleton 6 and the fourth skeleton 16, so as to ensure that they maintain low-temperature grinding when grinding coffee beans, and reduce the impact on the flavor and taste of the coffee powder during grinding.
