[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0025] like Figure 1-Figure 4 As shown, an adjustment device for a coffee machine is provided, comprising a grinding mechanism 1, a gear adjustment knob 2, a transmission member 3 and an adjustment assembly 4, wherein the adjustment assembly 4 comprises a potentiometer 401, the transmission member 3 is coaxially connected with the gear adjustment knob 2 and the potentiometer 401 for rotation, and when the gear adjustment knob 2 rotates, the transmission member 3 and the potentiometer 401 are driven to rotate synchronously, and the potentiometer 401 controls the grinding time of the grinding mechanism 1 according to the rotation angle of the gear adjustment knob 2.

[0026] Specifically, when the gear adjustment knob 2 is rotated, the transmission member 3 and the potentiometer 401 are driven to rotate, thereby changing the resistance value in the potentiometer 401 according to the rotation angle of the gear adjustment knob 2, thereby changing the voltage or current of the grinding mechanism 1, and adjusting the coarseness by the gear adjustment knob 2, thereby realizing automatic correction of the working time of the grinding mechanism 1 to correct the powder output of the grinding device, improve the taste of the coffee brewed by the coffee machine, and improve the user experience.

[0027] Through the above method, the user can easily adjust various parameters in the grinding process according to personal taste and the desired coffee type to achieve different taste requirements. The user can use the gear adjustment knob 2 to accurately control the change in the rotation speed of the driving member 102 on the grinding mechanism 1, so as to achieve the desired grinding effect. For example, the user can rotate the gear adjustment knob 2 counterclockwise to make the potentiometer 401 output a lower current value, thereby reducing the grinding time of the driving member 102 on the grinding mechanism 1. Conversely, the user can rotate the gear adjustment knob 2 clockwise to increase the output current value of the potentiometer 401, thereby increasing the grinding time of the driving member 102 on the grinding mechanism 1. In this way, different grinding times can be given at different coarse and fine gears to achieve a consistent powder output.

[0028] Further, if Figure 1-Figure 4 As shown, the adjustment assembly 4 includes an electronic component 402 , and the electronic component 402 is electrically connected to the potentiometer 401 .

[0029] Specifically, the grinding mechanism 1 includes a grinding assembly 101 and a driving member 102 for driving the grinding assembly 101 to rotate, and the driving member 102 is electrically connected to the adjusting assembly 4 .

[0030] Specifically, the user uses the gear adjustment knob 2 to accurately control the coarseness of the grinding component 101, and changes the resistance value in the potentiometer 401 according to the rotation angle of the gear adjustment knob 2, thereby changing the voltage or current of the driving component 102. When the resistance value of the potentiometer 401 is large, the grinding time is shorter and the ground coffee powder is coarser. When the resistance value of the potentiometer 401 is small, the grinding time is increased to make the powder particle size more uniform and the ground coffee powder is finer, thereby achieving the purpose of correcting the powder output.

[0031] 11. Further, if Figure 1 As shown, the regulating device further comprises a control module 5 , which is electrically connected to the driving member 102 and the potentiometer 401 . The control module 5 regulates the grinding time of the driving member 102 according to the resistance value of the potentiometer 401 .

[0032] Specifically, each time the gear adjustment knob 2 rotates one gear, the potentiometer 401 also rotates one gear and sends the resistance information to the control module 5. The control module 5 instructs the drive component 102 to increase or decrease a certain working time according to the collected resistance information, so as to adjust the powder output according to the coarseness of the grinding.

[0033] Further, if Figure 1-Figure 4 As shown, the adjusting device further comprises a positioning seat 6, and the electronic components 402 are fixedly mounted on the positioning seat 6 by screws and / or buckles. It has a simple structure and reliable performance.

[0034] Further, if Figure 1 and Figure 4 As shown, the positioning seat 6 is provided with an opening 601 for the rotating shaft 301 of the transmission member 3 to pass through. After passing through the opening 601 , the rotating shaft 301 is rotatably connected with the connecting shaft 201 of the gear adjustment knob 2 .

[0035] Specifically, after the rotating shaft 301 passes through the opening 601 , the rotating shaft 301 is matched and connected with the connecting shaft 201 , so that the transmission member 3 is driven to rotate when the gear adjustment knob 2 is rotated.

[0036] Further, if Figure 1 and Figure 3 As shown, a mounting hole 3011 is provided on the rotating shaft 301 , and an output shaft 4011 of the potentiometer 401 is interference-fitted with the mounting hole 3011 .

[0037] Specifically, the output shaft 4011 is interference-fitted with the mounting hole 3011 , so that the transmission member 3 is driven to rotate when the gear adjustment knob 2 is rotated, and the output shaft 4011 of the potentiometer 401 rotates along with the transmission member 3 .

[0038] Further, if Figure 4As shown, the transmission member 3 is provided with a positioning rib 302 , and the positioning seat 6 is provided with a blocking portion 602 . When the transmission member 3 rotates, the positioning rib 302 contacts the blocking portion 602 .

[0039] Specifically, when the gear adjustment knob 2 is rotated, the transmission member 3 is driven to rotate. When the transmission member 3 is rotated to a certain angle, the positioning rib 302 contacts the blocking portion 602 to prevent the user from over-rotating, thereby improving the reliability of the product.

[0040] Further, if Figure 1 and Figure 2 As shown, the transmission member 3 is provided with a gear portion 303, and the grinding mechanism 1 also includes an adjusting member 7 for adjusting the upper and lower gaps of the conical cutter. The adjusting member 7 is meshed with the gear portion 303, and the adjusting member 7 is driven to rotate when the transmission member 3 rotates.

[0041] Specifically, the transmission member 3 is provided with saw teeth meshing with the gear portion 303 . When the transmission member 3 rotates, the movement of the gear is transmitted to enable the adjustment member 7 to rotate simultaneously, thereby adjusting the coarseness of the grinding assembly 101 .

[0042] Further, if Figure 1 and Figure 5 As shown, the adjustment device also includes a frame 8, a positioning portion 603 is provided at the bottom of the positioning seat 6, a slot 801 is provided on the frame 8 to cooperate with the positioning portion 603, the positioning portion 603 is inserted into the slot 801, and the positioning seat 6 is fixedly mounted on the frame 8 by screws and / or buckles.

[0043] By adopting the above arrangement, the positioning seat 6 can be stably installed on the frame 8, and the structure is simple and the performance is reliable.
