Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of beverage making equipment, in particular to a grinding device. BACKGROUND

[0002] In the equipment for making beverages such as coffee machines, a grinding device is usually built-in. Taking a coffee machine as an example, the grinding device in the coffee machine, which can be commonly referred to as a kind of mechanism of a bean grinder, serves as a crucial component in the coffee machine, responsible for grinding coffee beans into coffee powder suitable for brewing.

[0003] Generally speaking, the working principle of the bean grinder of the coffee machine is relatively simple: when the coffee beans are put into the bean grinder bin, the motor is started and drives the grinding disc or grinding knife to rotate. The rotating grinding disc or grinding knife breaks and grinds the coffee beans into powder; then the powder is discharged through the powder outlet.

[0004] Specifically, the existing bean grinder mostly faces a defect: the dynamic bean grinding knife assembly part is easy to cause the coffee powder to enter the gap in the height direction between the dynamic bean grinding knife assembly and the bean grinding base during the process of grinding beans, thereby affecting the accuracy of the bean grinder in grinding coffee powder. Based on this, a kind of bean grinder for coffee machine and beverage machine is disclosed in a Chinese patent for invention with the authorization publication number CN106943022B, the bevel gear transmission assembly includes a tension generator, a bearing and a bevel gear, the dynamic bean grinding knife assembly includes a propeller, a wear-resistant sheet and a wear-resistant gasket, the wear-resistant gasket is arranged on the bean grinding base, the tension generator is placed in the upper gap of the bearing between the bearing and the bean grinding base, so that the bearing receives the downward thrust of the tension generator, realizing that the bottom of the propeller and the wear-resistant sheet always keep close when working. Through the above-mentioned mode, the bean grinder for coffee machine and beverage machine realizes that the bottom of the propeller and the wear-resistant sheet always keep close with compression force when working, reduces the upper gap of the wear-resistant sheet, makes the coffee powder not easy to enter the upper gap of the wear-resistant sheet, and improves the accuracy of the bean grinder in grinding coffee powder.

[0005] In addition, for the burr coffee machine, a large amount of coffee powder will be left in the coffee powder channel after each grinding of coffee beans, which will be brewed until the next time. The residual coffee powder will affect the taste of the coffee, and even deteriorate. Based on this, another Chinese invention patent with publication number CN102327065A also discloses a coffee grinder, which comprises a body, an automatic coffee bean grinding device, a brewing device, a control device and a coffee container. The lower part of the automatic coffee bean grinding device is provided with a powder outlet, and a coffee powder channel is arranged between the automatic coffee bean grinding device and the powder outlet. The brewing device comprises a coffee basket for containing coffee powder, which is arranged below the powder outlet. The coffee container is located below the coffee outlet of the brewing device. An automatic powder cleaning device is arranged in the coffee powder channel. The automatic powder cleaning device comprises a powder cleaning motor and a powder cleaning brush. The powder cleaning motor is installed on the automatic coffee bean grinding device, and the powder cleaning brush is installed on the output shaft of the powder cleaning synchronous motor. The powder cleaning brush is located in the coffee powder channel, and the powder cleaning synchronous motor is electrically connected with the control device. The coffee grinder can automatically sweep out the coffee powder left in the coffee powder channel after the grinding of coffee beans by the grinding device, and can ensure that the sealing plate effectively seals the powder outlet.

[0006] In addition, the coffee machine disclosed in the prior art also has the defect that the coffee bean feeding process is not smooth. Based on this, another Chinese invention patent with authorization publication number CN106943022B discloses a coffee grinder, which comprises a hopper, a cover plate, a protective sleeve, a cutter head, a cutter sleeve, a powder throwing disc and a main shaft driven by a motor. The cover plate is located above the discharge port, the discharge port is communicated with the cutter sleeve through the protective sleeve, the top end of the main shaft is fixed with a connecting shaft, the outer circumference of the connecting shaft is provided with external threads; the guide sleeve of the cover plate is matched with the connecting shaft through spline; the upper surface of the cover plate is provided with a plurality of first pushing ribs for pushing coffee beans from the center of the cover plate to the outer circumference of the cover plate. The device can make the feeding more smooth when the coffee beans are regrinded.

[0007] However, the above-mentioned grinding device still has the technical problem that the grinding fineness of coffee beans cannot be adjusted or cannot be conveniently and effectively adjusted. Specifically, as people's desire for high-quality life increases, people's requirements for beverage machines, especially coffee machines, are increasingly stringent, and the competition in the coffee machine market is becoming increasingly fierce. For the coffee bean grinding device, a convenient and easy grinding adjustment mechanism can facilitate users to adjust the fineness of coffee beans at any time, so as to adapt to different brewing methods and taste preferences of users, and thus improve the core competitiveness of the coffee machine.

[0032] Specifically, when the grinding device is in the working process, the coffee beans and other raw materials waiting for grinding are dropped from the external storage bin into the bearing structure 1 and located in the grinding area of the conical cutter structure 3 and the adjustable cutter disc structure 4. Then, the driving mechanism 2 can drive the conical cutter structure 3 to rotate, and then force the coffee beans and other raw materials to be crushed and ground by the cooperation between the conical cutter structure 3 and the adjustable cutter disc structure 4; until the coffee beans and other raw materials are ground to the preset fineness, enter the inner cavity of the bearing structure 1 into the dropping structure 6; and flow into the next station, such as the brewing station, from the dropping structure 6. If the user needs to adjust the grinding fineness of the coffee beans and other raw materials, the adjusting structure 5 can be twisted to drive the adjustable cutter disc structure 4 to rotate relative to it, and then the adjustable cutter disc structure 4 is relatively close to or away from the rotating range of the conical cutter structure 3 in the vertical direction; so that the gap between the adjustable cutter disc structure 4 and the conical cutter structure 3 is reduced or increased; and then the fineness of the coffee beans and other raw materials can be adjusted. It can be seen that the grinding device can conveniently and reliably adjust the fineness of the ground powder product, and solves the technical problem of how to improve the use convenience of the adjusting mechanism of the grinding device.

[0033] Further, in a specific embodiment, the bearing structure 1 has a main body structure 101, a seat body structure 102, a containing cavity 103, a threaded connection part 104 and an adjusting rod connecting part 105; the bottom of the main body structure 101 is connected with the seat body structure 102, the containing cavity 103 is arranged in the main body structure 101, and the threaded connection part 104 is arranged on the upper part of the main body structure 101; the adjusting rod connecting part 105 is arranged on the side surface of the main body structure 101. The adjustable cutter head structure 4 has an adjusting sleeve ring 401, a cutter head sleeve connector 402 and an inner cutter head structure 403; the adjusting sleeve ring 401 has a sleeve ring main body 401a, a sleeve ring connecting part 401b and an outer tooth ring structure 401c; the sleeve ring connecting part 401b is arranged in the inside of the sleeve ring main body 401a, and the sleeve ring connecting part 401b is connected with the threaded connection part 104 in a matched mode; the outer tooth ring structure 401c is connected with the adjusting rod 5 in a matched mode; the cutter head sleeve connector 402 is connected with the adjusting sleeve ring 401 and the inner cutter head structure 403 respectively, the cutter head sleeve connector 402 is movably arranged in the containing cavity 103, and the inner cutter head structure 403 is arranged opposite to the conical cutter structure 3.

When the user twists the scale knob 501, the adjustment rod 502 can rotate in the adjustment rod connecting portion 105, and then drive the adjustment gear structure 503 in a predetermined direction. When the adjustment gear structure 503 rotates, it can drive the sleeve ring body 401 through the meshing transmission between the outer gear ring structure 401c and the sleeve ring body 401, so that the threaded connection structure in the inner ring of the sleeve connecting portion 401b cooperates with the threaded connecting portion 104 to drive the adjustment sleeve 401 to move downward or upward along the thread. The inner cutter disc structure 403 is connected to the cutter disc sleeve 402 in advance by in-mold injection or the like, and the cutter disc sleeve 402 is connected to the sleeve ring body 401 by buckle connection or the like.

Specifically, in this embodiment, the building rubber seat 102b is a seat body structure made of rubber and the like, which can offset or slow down the vibration generated when the driving mechanism 2 drives the conical cutter structure 3 to work, thereby playing a role in noise reduction.
