Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a coffee grinder. Background Technology

[0002] Chinese utility model patent CN222149710U discloses a modular coffee machine, including a frame and a grinding module, a brewing module, and a boiler module detachably mounted on the frame. The frame has an installation area where the grinding module, and / or brewing module, and / or boiler module are detachably mounted to form a coffee grinder, a coffee brewer, or a fully automatic coffee machine. Specifically, the grinding module, brewing module, and boiler module are modularized and embedded in the frame; thus, the appropriate module combination can be selected according to actual needs. When grinding coffee beans is required, the grinding module is installed in the installation area of ​​the frame to form an independent grinding machine; when brewing coffee is required, the brewing module and boiler module are combined and installed in the installation area of ​​the frame to form a coffee brewer; when both grinding and brewing are required, the grinding module, brewing module, and boiler module are all installed in the installation area of ​​the frame to form a complete fully automatic coffee machine. Because the motor is arranged vertically, the grinding module, brewing module, and boiler module of the modular coffee machine can only be arranged horizontally and parallelly. This results in a coffee machine with a large horizontal width, which is almost the same as its length, resulting in a coffee machine with a large size and a non-compact structure.

[0024] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0025] like Figures 1 to 3As shown, the present invention provides a coffee grinder, which includes a body 1 with a water tank 11, a grinding assembly with a support 21, and a brewing assembly with a brewing head 31. The grinding assembly is located on the upper front side of the coffee grinder in the front-back direction, the water tank 11 is located on the rear side of the coffee grinder in the front-back direction, the brewing assembly 3 is located between the grinding assembly 2 and the water tank 11, and the support 21 is located on the front side of the brewing head 31, adjacent to each other and higher than or flush with the brewing head 31. The grinding assembly is positioned at the upper front of the coffee grinder, effectively utilizing the vertical space of the body 1 and reducing its width. The water tank 11 is located at the rear of the coffee grinder, with the brewing assembly positioned between the grinding assembly and the water tank 11. The support 21 is located adjacent to and higher than or flush with the brewing head 31, positioned in front of it. This alignment ensures that after the funnel 4 has collected the coffee grounds from the grinding assembly, it can be locked onto the brewing head 31 for brewing. The support 21 does not obstruct the funnel 4, allowing it to remain securely locked. Compared to existing technologies, this design significantly reduces the width of the coffee grinder while maintaining a relatively constant length and height, resulting in a smaller overall size, a more compact structure, and less space occupied during use.

[0026] Specifically, such as Figures 4 to 6 As shown, the coffee grinding assembly also includes a bean hopper 22, a moving grinding wheel 23, a fixed grinding wheel 24, an adapter, and a motor 25. The drive motor 25 is horizontally fixed above the brewing head 31. The moving grinding wheel 23, the fixed grinding wheel 24, and the adapter are all located inside the bean hopper 22. The fixed grinding wheel 24 is fixed to the bottom of the bean hopper 22. One end of the adapter is connected to the rotating shaft of the motor 25, and the other end is connected to the moving grinding wheel 23. The motor 25 is horizontally fixed above the brewing head 31, and the rotating shaft of the motor 25 also rotates horizontally. The adapter converts the horizontal rotation of the rotating shaft into vertical rotation. The coffee grinding assembly is arranged as described above, making its structure compact so that it can be placed on the upper front side of the coffee grinder in the front-to-back direction.

[0027] Furthermore, the brewing assembly also includes a water pump 32 and a boiler 33. The water pump 32 and the boiler 33 are installed between the brewing head 31 and the water tank 11. One end of the brewing head 31 is connected to one end of the boiler 33, the other end of the boiler 33 is connected to one end of the water pump 32, and the other end of the water pump 32 is connected to the water tank 11, so that the brewing head 31, the boiler 33, the water pump 32 and the water tank 11 are sequentially connected to each other.

[0028] More specifically, the adapter includes a base 26, a driving bevel gear 27, an intermediate shaft 28, a driven bevel gear 29, and a driven shaft 30. The driving bevel gear 27 is fixed on the intermediate shaft 28, and the driven bevel gear 29 is fixed on the driven shaft 30. Both the intermediate shaft 28 and the driven shaft 30 are pivotally connected inside the base 26. The right end of the intermediate shaft 28 is connected to the rotating shaft of the motor, and the moving grinding wheel 23 is fixed at the lower end of the driven shaft 30.

[0029] Optionally, the support 21 is located at the bottom of the bean container 22. A powder guide cylinder 211 is provided at the center of the support 21. A wheel cover 212 is provided in the middle of the powder guide cylinder 211. Multiple connecting ribs 213 are provided between the wheel cover 212 and the powder guide cylinder 211, and a through hole 214 is formed between the connecting ribs 213 to allow coffee powder to pass through. A protective cover 221 is provided on the outside of the adapter. The protective cover 221 is suspended in the middle of the bean container 22. The protective cover 221 is suspended in the middle of the bean container 22, so that the coffee beans put into the bean container 22 enter the bottom of the bean container 22 through the gap between the protective cover 221 and the bean container 22. After being ground by the moving grinding wheel 23 and the fixed grinding wheel 24, they fall directly into the funnel 4 installed on the support 21 under the action of gravity through the through hole 214.

[0030] In addition, the machine body 1 is equipped with a first support frame 12 and a second support frame 13. The water pump 32 is fixed on the first support frame 12, and the boiler 33 is fixed on the second support frame 13 and located above the water pump 32. The boiler 33 is positioned above the water pump 32, which can effectively utilize the vertical space of the machine body 1 and reduce the length of the coffee grinder. The machine body 1 is equipped with a third support frame 14. One end of the third support frame 14 is fixedly connected to the brewing head 31, and the other end is fixedly connected to the motor 25, so that the motor 25 is fixed on the third support frame 14.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
