The assembly cover 34 and the mounting box 102 are detachably connected. The surface of the assembly cover 34 is provided with an electric drive device 33. The output end of the electric drive device 33 is connected to a rotating shaft via a coupling. One end of the rotating shaft passes through the assembly cover 34 and is engaged with the power end of the grinding assembly 104. The surface of the assembly cover 34 is provided with an operation panel cover 32. The surface of the operation panel cover 32 is provided with a mounting cover 31. The surfaces of the mounting cover 31 and the operation panel cover 32 are threadedly engaged. The electric drive device 33 and the assembly cover 34 are located inside the mounting cover 31.

[0023] During implementation, rotating the control panel cover 32 causes the assembly cover 34 to rotate against the inner wall of the mounting box 102. The assembly cover 34 is then assembled onto the surface of the mounting box 102 through the threaded engagement between the assembly cover 34 and the inner wall of the mounting box 102. At this time, the output end of the electric drive device 33 automatically engages with the power input end of the grinding assembly 104, connecting the electric drive device 33 and the grinding assembly 104, thereby assembling the mounting cover 31 onto the surface of the mounting box 102. The user can then operate the buttons on the surface of the control panel cover 32 to drive the mounting cover 31. The electric drive unit 33 inside the cover 31 works, driving the grinding component 104 to rotate inside the grinding box 101 to grind the coffee beans. The ground coffee powder automatically falls into the storage tank 1 under the action of gravity, where it is stored. When the user disassembles the automatic grinding mechanism 3, they only need to rotate the mounting cover 31 to remove the mounting cover 31, electric drive unit 33 and assembly cover 34 from the surface of the mounting box 102, thus realizing the automatic grinding function of the coffee grinder.

[0024] Furthermore, such as Figure 2 and Figure 5As shown, a manual grinding mechanism 2 is provided on one side of the storage tank 1. The manual grinding mechanism 2 consists of a positioning cylinder 21, a mounting cover 22, a rotating rod 23, and a mounting component 24. The mounting cover 22 is provided on one side of the storage tank 1. A rotating rod 23 is provided on the surface of the mounting cover 22. The rotating rod 23 and the surface of the mounting cover 22 rotate and cooperate with each other. A handle is provided on the surface of the rotating rod 23. A mounting component 24 is installed on the surface of the rotating rod 23. One end of the mounting component 24 extends into the interior of the rotating rod 23 and engages with the inner wall of the handle. The inner wall of the mounting cover 22 is threaded with the surface of the mounting box 102. A positioning cylinder 21 is provided on the inner wall of the mounting cover 22. The positioning cylinder 21 and the inner wall of the mounting cover 22 rotate and cooperate with each other. The surface of the positioning cylinder 21 is fixed to the surface of the rotating rod 23. One end of the positioning cylinder 21 extends into the interior of the mounting box 102 and the grinding box 101 and engages with the power end of the grinding assembly 104.

[0025] In practice, if the user chooses to manually grind coffee beans, the user removes the automatic grinding mechanism 3 from the surface of the mounting box 102, and then, under the action of the mounting part 24, installs the handle on the surface of the rotating rod 23. The user then places the mounting cover 22 on the surface of the mounting box 102, rotates the mounting cover 22, and, with the threaded engagement between the mounting cover 22 and the mounting box 102, assembles the mounting cover 22 onto the surface of the mounting box 102. This causes the mounting cover 22 to drive the positioning cylinder 21 to automatically engage with the power input end of the grinding assembly 104, thus securing the positioning cylinder 21 to the grinding assembly 104. The user then rotates the rotating rod 23, causing the rotating rod 23 to drive the positioning cylinder 21 to rotate on the inner wall of the mounting cover 22. Under the action of the positioning cylinder 21, the grinding assembly 104 rotates inside the grinding box 101. Power is output to the grinding assembly 104 by manually cranking the rotating rod 23 and the handle, and the grinding assembly 104 grinds the coffee beans, thus realizing the manual grinding function of the coffee grinder.

[0026] Working Principle: In use, first place the storage tank 1 in the designated location. Depending on the actual usage needs, the user can choose to connect the automatic grinding mechanism 3 or the manual grinding mechanism 2 to the power input end of the grinding assembly 104. If the user selects automatic grinding of coffee beans, the user places the control panel cover 32 on the surface of the mounting box 102 and then rotates the control panel cover 32, causing the assembly cover 34 to rotate against the inner wall of the mounting box 102. With the threaded engagement between the assembly cover 34 and the inner wall of the mounting box 102, the assembly cover 34 is assembled onto the surface of the mounting box 102. At this time, the output end of the electric drive device 33 automatically engages with the power input end of the grinding assembly 104, connecting the electric drive device 33 to the grinding assembly 104, thereby assembling the mounting cover 31 onto the mounting box 104. On the surface of the 02, the user operates the buttons on the surface of the control panel cover 32 to drive the electric drive device 33 inside the mounting cover 31. Under the action of the electric drive device 33, the grinding component 104 rotates inside the grinding box 101 to grind the coffee beans. The ground coffee powder falls automatically into the storage tank 1 under the action of gravity and is stored inside the storage tank 1. When the user disassembles and reassembles the automatic grinding mechanism 3, he / she only needs to rotate the mounting cover 31 to remove the mounting cover 31, the electric drive device 33 and the assembly cover 34 from the surface of the mounting box 102 to realize the automatic grinding function of the coffee grinder. This makes it convenient for the user to disassemble and reassemble the automatic grinding mechanism 3 when using the coffee grinder, making the coffee grinder more convenient for the user.

[0027] Subsequently, if the user chooses to manually grind coffee beans, the user removes the automatic grinding mechanism 3 from the surface of the mounting box 102. Under the action of the mounting component 24, the user then attaches the handle to the surface of the rotating rod 23. The user then places the mounting cover 22 on the surface of the mounting box 102 and rotates it. The mounting cover 22 is then assembled onto the surface of the mounting box 102 through the threaded engagement with the mounting box 102. This causes the mounting cover 22 to automatically engage the positioning cylinder 21 with the power input end of the grinding assembly 104, thus securing the positioning cylinder 21 to the grinding assembly 104. The user then rotates the rotating rod 23, causing the rotating rod 23 to... The positioning cylinder 21 rotates on the inner wall of the mounting cover 22. Under the action of the positioning cylinder 21, the grinding component 104 rotates inside the grinding box 101. Power is output to the grinding component 104 by hand-cranking the rotating rod 23 and the handle. Under the action of the grinding component 104, the coffee beans are ground to realize the manual grinding function of the coffee grinder. This makes it convenient for users to select the grinding mode of coffee according to their needs, making the coffee grinder more practical. The grinding component 104 is an existing grinding mechanism and belongs to the prior art. Finally, the coffee grinder is used.
