Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a coffee machine. Background Technology

[0002] In existing technology, most coffee grinders typically include an inner grinding blade, an outer grinding blade, and a drive assembly. The outer and inner grinding blades are positioned opposite each other, forming a certain grinding gap. The inner grinding blade is driven to rotate relative to the outer grinding blade, grinding the coffee beans located between them into coffee powder. The size of the grinding gap determines the coarseness of the resulting coffee powder; therefore, controlling the grinding gap between the two grinding blades is quite important. Moreover, the existing coffee grinders have relatively complex structures for adjusting the grinding gap. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0026] Example:

[0027] like Figures 1 to 3 As shown, this embodiment provides a coffee machine, including:

[0028] The cup body 1 has a powder storage compartment 2 and a grinding compartment 3 defined from bottom to top inside the cup body 1. The upper end of the powder storage compartment 2 is open and connected to the lower end of the grinding compartment 3.

[0029] The burr assembly 4 is disposed in the grinding chamber 3 to grind coffee beans;

[0030] The drive component 5 is located inside the cup body 1, and its output end passes through the powder storage bin 2 and is connected to the grinding core 41.

[0031] In this embodiment, a powder storage chamber 2 and a grinding chamber 3 are defined from bottom to top inside the cup body 1. A through hole is provided at the middle position of the lower end of the grinding chamber 3. Since the upper end of the powder storage chamber 2 is open, the lower end of the grinding chamber 3 is connected to the upper end of the powder storage chamber 2 through the through hole. The drive component 5 is located at the lower end of the cup body 1. The output end of the drive component 5 passes through the powder storage chamber 2 and is connected to the grinding core 41 so that the drive component 5 drives the burr assembly 4 to rotate, thereby grinding the coffee beans in the grinding chamber 3. The ground coffee powder passes through the through hole and the open end of the powder storage chamber 2 and enters the powder storage chamber 2 in sequence, thus completing the grinding process of coffee beans. More preferably, since the powder storage chamber 2 is detachably located at the lower end of the grinding chamber 3, the user can separate the grinding chamber 3 from the powder storage chamber 2 and then pour out the coffee powder in the powder storage chamber 2. Its structure is simple and easy to operate, which can further improve the user experience.

[0032] Furthermore, the drive assembly 5 includes a drive motor 51 and a rotating shaft 52, wherein the drive motor 51 is disposed inside the cup body 1, one end of the rotating shaft 52 is connected to the output end of the drive motor 51, and the other end extends from bottom to top and is connected to the grinding core 41.

[0033] Preferably, a boss 21 is provided in the powder storage hopper 2, and the rotating shaft 52 passes through the boss 21 at the end away from the drive motor 51 and is connected to the grinding core 41.

[0034] In this embodiment, the drive motor 51 is installed inside the cup body 1, and a boss 21 is provided in the powder storage compartment 2. The lower end of the rotating shaft 52 is connected to the output end of the drive motor 51, and its upper end passes through the boss 21 and is connected to the lower end of the grinding core 41, so that the drive motor 51 drives the grinding core 41 to rotate. The coffee beans are ground by the cooperation between the grinding sleeve 42 and the grinding core 41. The ground coffee powder passes through the through hole and the open end of the powder storage compartment 2 in sequence and enters the powder storage compartment 2, thus completing the grinding process of the coffee beans.

[0035] Specifically, it also includes a power switch 6 and a controller, wherein the power switch 6 is disposed on the outer wall of the cup body 1, and the controller is electrically connected to the power switch 6 and the drive assembly 5 respectively.

[0036] Preferably, it also includes a cover plate 7, which has an opening at the upper end of the grinding chamber 3, and the cover plate 7 is detachably installed at the opening.

[0037] In this embodiment, an opening is provided at the upper end of the grinding chamber 3, and a cover plate 7 is detachably installed at the opening. The user can open and close the opening by removing and installing the cover plate 7, so that the user can put coffee beans into the grinding chamber 3 through the opening. More preferably, the ground coffee powder enters the powder storage chamber 2 after passing through the open end of the powder storage chamber 2, thus completing the grinding process of coffee beans. Then the user separates the grinding chamber 3 from the powder storage chamber 2 to pour out the coffee powder in the powder storage chamber 2, thereby avoiding the user being scratched by the blade assembly 4 when taking coffee powder from the powder storage chamber 2.

[0038] Furthermore, it also includes a seal, which is located at the midpoint between the cover plate 7 and the grinding chamber 3.

[0039] Specifically, it also includes a sealing ring, which is located at the middle position between the grinding chamber 3 and the powder storage chamber 2.

[0040] Preferably, the internal space of the grinding chamber 3 has a funnel-shaped structure.

[0041] Furthermore, the burr assembly 4 includes a grinding core 41 and a grinding sleeve 42. The grinding core 41 is movably disposed in the grinding chamber 3, and the output end of the drive assembly 5 passes through the powder storage chamber 2 and connects to the grinding core 41. The grinding sleeve 42 is fitted on the outside of the grinding core 41, and the coffee beans are ground by the cooperation between the grinding sleeve 42 and the grinding core 41.

[0042] In particular, the burr assembly 4 also includes a burr head 43, which is located at the upper end of the grinding core 41, thereby further improving the grinding effect of coffee beans.

[0043] In this embodiment, a through hole is provided at the middle position of the lower end of the grinding chamber 3, and a grinding core 41 is movably disposed at the through hole. A grinding sleeve 42 is fitted around the outside of the grinding core 41. The drive motor 51 is located at the lower end of the internal space of the cup body 1, and the output end of the drive motor 51 is connected to the grinding core 41 through a rotating shaft 52 to drive the grinding core 41 to rotate. Thus, the coffee beans are ground by the cooperation between the grinding sleeve 42 and the grinding core 41. More preferably, the internal space of the grinding chamber 3 has a funnel-shaped structure, which facilitates the accumulation of coffee beans in the grinding chamber 3 at the position of the blade assembly 4, thereby greatly improving the grinding effect of the coffee beans.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
