The grinding device is tilted as a whole to achieve the effect that the ground coffee powder can quickly and accurately fall through the powder outlet conduit each time, which greatly improves the convenience; however, in actual use, it is found that the following disadvantages are found:

[0039] 1. The coaxial setting of the motor and the grinding assembly will cause the overall center of gravity of the grinder to be biased upward. In actual use, a large amount of coffee beans are placed in the bean bin, which aggravates the upward shift of the center of gravity. Therefore, a counterweight block needs to be added to the base of the grinder to ensure that the grinder can be placed stably.

[0040] 2. In terms of adjusting the powder diameter, it is difficult to adjust the grinding coarseness of the coffee powder by adjusting the powder coarseness hardware; therefore, a coffee grinder with a more reasonable structure is urgently needed to solve the above technical problems;

[0041] 3. The middle shell of the grinding device forms a feed port and a discharge port, and the bean storage bin is directly connected to the feed port. After the grinding device grinds the coffee beans contained in the bean storage bin, the coffee powder flows out from the discharge port. The coffee delivery channel of the above structure as a whole is relatively short, and the discharge port, grinding chamber and feed port are connected to the air, which easily causes the air to flush with water and directly affect the humidity of the coffee beans, which will affect the subsequent brewing taste.

[0045] As for the specific scheme of the linkage structure 3, the linkage structure 3 can be implemented by using a universal joint structure 31, and the specific installation is as follows: the first coupling end of the universal joint structure 31 is fixedly connected to the output shaft of the driving motor 11, and the second coupling end is fixedly connected to the driven end; the universal joint structure 31 is used to realize the transmission of the driving motor 11 and the grinding device 2 not on the same working axis, and then the installation position of the driving motor 11 can be changed, so that the driving motor 11 is installed on the seat body 1 as the main counterweight structure; the universal joint structure 31 can be specifically selected from a cross universal joint, a spherical universal joint, a roller universal joint, etc., or other universal joint structures 31 that can achieve the above-mentioned assembly effect;

[0046] In another specific scheme, the linkage structure 3 includes a first bevel gear 32 and a second bevel gear 33. The first bevel gear 32 is fixedly mounted on the output shaft of the drive motor 11, and the second bevel gear 33 is fixedly connected to the driven end, and the first bevel gear 32 and the second bevel gear 33 are meshed. It is not difficult to understand that the first bevel gear 32 and the second bevel gear 33 are meshed and transmitted with each other with a suitable transmission ratio, thereby realizing transmission on which the drive motor 11 and the grinding device 2 are not on the same working axis, and thus the installation position of the drive motor 11 can be changed, so that the drive motor 11 is installed as the main counterweight structure on the seat body 1.

[0047] In this embodiment, a main shell 4 for accommodating the grinding device 2 is also included, one end of the main shell 4 is connected to the base body 1, and the other end is connected to the bean storage bin 6; the end face of the adjusting portion 5 extends to one side surface of the main shell 4; it is not difficult to understand that the main shell 4 is used to cover and protect the grinding device 2, the driving motor 11 and the linkage structure 3 to prevent foreign matter from invading the linkage structure 3, to prevent jamming during transmission, and finally to prevent the grinding device 2 from working normally; the bean storage bin 6 can store a certain amount of coffee beans to avoid the cumbersomeness of adding small amounts and multiple times to the user; in a specific solution, the bean storage bin 6 is composed of a main bin body and a cover body, and the enclosure forms a accommodating cavity for storing coffee beans, and a material port is provided at the bottom of the main bin body, and the material port is connected to the feed port 21 of the grinding device 2 through a feeding pipe. So as to realize stable transmission of the coffee beans in the accommodating chamber to the grinding device 2, and realize grinding of the coffee beans; in a further scheme, it also includes a valve component for sealing the bean storage bin, the valve component includes a valve plate 61, a connecting shaft 62 and a force knob 63, the valve plate 61 is located between the main bin body and the feeding pipe, one end of the connecting shaft 62 is connected to the valve plate, and the other end passes through the profile of the main bin body and protrudes to the surface of the cover body, and the protruding end is fixedly connected to the force knob 63. When in use, the user only needs to rotate the force knob, and the valve plate follows the force knob to rotate through the connecting shaft, thereby forming a blocking state for the material port and the feed port 21, thereby enhancing the overall sealing performance of the bean storage bin and preventing the influence of moisture caused by the pipeline connection; and the blocking condition of the valve plate can be adjusted in time to grind the coffee beans quantitatively, so that the user can control the required grinding amount of coffee beans.

[0048] In this embodiment, the grinding device 2 includes a grinding bin 23, and a first grinding disc 24 and a second grinding disc 25 located in the grinding bin 23 and forming a grinding space. The first grinding disc 24 is provided with a transmission shaft forming a driven end on a side away from the second grinding disc 25; the feed inlet 21 and the discharge outlet 22 are located on the outer wall of the grinding bin 23 and connected to the grinding space; the adjustment part 5 is provided with an adjustment spring 54 for connecting with the second grinding disc 25; it is not difficult to understand that the types of grinding discs are roughly divided into two types: conical grinding discs and flat grinding discs. The advantage of the conical grinding disc is that it is not easy to hide powder due to the inclined grinding surface; the grinding of the flat grinding disc The characteristics are opposite to those of the conical grinding disc. The advantage is that the grinding is uniform, but it is easy to hide powder due to the flat surface. The first grinding disc 24 and the second grinding disc 25 of the present application are preferably flat grinding discs. Since the grinding device 2 is tilted, the first grinding disc 24 and the second grinding disc 25 are also tilted at the same angle, which reduces the problem of powder hiding in the flat grinding disc. During use, the user can change the distance between the first grinding disc 24 and the second grinding disc 25 by adjusting the spring 54. It can be understood that the smaller the distance, the smaller the grinding space and the smaller the powder diameter, and vice versa.

[0049] In a specific solution, the adjusting portion 5 includes a knob 51, a threaded column 52 and a spring column 53 connected in sequence, the cross-sectional diameter of the spring column 53 is smaller than the cross-sectional diameter of the threaded column 52; the adjusting spring 54 is sleeved on the spring column 53 and squeezes the second grinding disc 25; the grinding bin 23 is provided with a threaded hole adapted to the threaded column 52; it is not difficult to understand that when the user needs to adjust the diameter of the ground powder, he only needs to adjust the knob 51 so that the threaded column 52 is screwed into or out of the threaded hole and relatively stopped at the expected position, driving the spring column 53 to move while changing the degree of squeezing of the second grinding disc 25 by the adjusting spring 54, and when in the stopped state, the second grinding disc 25 maintains the squeezing degree, that is, the grinding space between the second grinding disc 25 and the first grinding disc 24 is changed, and the user can grind coffee powder of the expected powder diameter according to demand.

[0050] In a specific solution, the grinding device 2 also includes a cache bin 26, which is arranged in the grinding bin 23, and the cache bin 26 always abuts against the second grinding disc 25 through the adjustment spring 54; the outer wall of the cache bin 26 is provided with a feeding channel connecting the feeding port 21 and the grinding space; it is not difficult to understand that the cache bin 26 covers the grinding disc opening of the second grinding disc 25, and the grinding disc opening is connected to the grinding space, and the coffee beans can smoothly fall into the grinding disc opening and enter the grinding space for grinding through the cache bin 26, which increases the grinding stability of the coffee beans and forms a certain buffering performance to prevent a large amount of coffee beans from gathering and causing grinding to become stuck and unevenly falling.

[0051] In this embodiment, the grinding bin 23 is composed of a main cylinder and a covering portion, and the transmission shaft protrudes out of the covering portion away from the main cylinder. The edge of the first grinding disc 24 is provided with a powder scraping protrusion 27. It is not difficult to understand that when the driving motor 11 works, it drives the first grinding disc 24 to rotate and cooperates with the second grinding disc 25 to grind the coffee beans. The powder scraping protrusion 27 also rotates with the first grinding disc 24. The powder formed by grinding is cleaned and gathered by the powder scraping protrusion 27 and can flow out from the discharge port 22 to be collected and brewed by the user.

[0052] In this embodiment, it also includes a powder outlet pipe 12, one end of which is connected to the discharge port 22, and the other end extends to the powder receiving portion 13 of the base body 1; the powder outlet pipe 12 makes it more convenient for users to use the ground coffee powder without causing a large amount of coffee powder to remain inside the main shell 4.

[0053] In a further solution, the outer wall of the powder receiving portion 13 is provided with a snap plate 14 for snapping into the powder container; in this embodiment, the snap plate 14 stably fixes the powder container in the powder receiving portion 13 during the powder receiving operation, facilitating the user's subsequent brewing process.

[0054] The advantages of the utility model are:

[0055] 1. The output shafts of the grinding device and the driving motor are not on the same axis through the linkage structure, so that the driving motor is placed on the seat body 1. The structure is reasonable and the weight of the driving motor itself is cleverly used to form the counterweight structure of the seat body 1, so that the center of gravity is formed more reasonably;

[0056] 2. The size of the grinding space can be adjusted by the adjustment part to obtain powders with different diameters. The operation is simple and convenient, which is convenient for users to process different types of coffee beans to obtain powders with expected diameters.

[0057] 3. The valve makes the bean storage bin form an independent closed state, so that the moisture in the air cannot enter the bean storage bin through the discharge port, grinding space and feed port in sequence, so that the coffee beans in the bin are not affected by the water molecules in the air, thereby enhancing the storage capacity of the coffee beans.

[0058] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
