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.

[0033] like Figure 1-Figure 8 As shown, a cleaning structure and a bean grinding coffee machine are provided. The cleaning structure includes a cleaning seat 1, on which cleaning teeth 2 are provided. The cleaning teeth 2 are made of at least a hard material, and the cleaning teeth 2 are gradually extended from the cleaning seat 1 from top to bottom.

[0034] Specifically, the cleaning seat 1 can push and sweep the abrasive during the cleaning process through the cleaning teeth 2, thereby avoiding unevenness and residue of the abrasive; the inclined design of the cleaning teeth 2 enables it to more deeply contact different levels of the grinding component 5, especially the bottom and edges, thereby more effectively removing accumulated abrasive.

[0035] Selecting durable and non-damageable hard cleaning teeth 2 can extend the service life of the cleaning seat 1 on the one hand; on the other hand, it can keep the inside of the grinding component 5 clean and avoid residue; the hard cleaning teeth 2 can be made of high-strength stainless steel or plastic with a specific hardness.

[0036] Further, if Figure 1-Figure 5 As shown, there are a plurality of cleaning teeth 2, which are evenly spaced at the lower end of the cleaning seat 1, and an air-avoiding space 3 is formed between every two cleaning teeth 2; every two cleaning teeth 2 are in an N shape; and every two cleaning teeth 2 are connected by an arc-shaped smooth transition.

[0037] Specifically, a plurality of cleaning teeth 2 are evenly distributed at the lower end of the cleaning seat 1, ensuring extensive cleaning coverage; the N-shaped design and arc-shaped transition connection help to stir and clean the abrasive more thoroughly, preventing the abrasive from accumulating between the cleaning teeth; the air space 3 between every two cleaning teeth 2 allows the abrasive to move freely during the cleaning process, reducing blockage and optimizing the fluidity of the abrasive, which helps to discharge residues during the cleaning process.

[0038] Further, if Figure 2 As shown, the cleaning tooth 2 includes a contact surface 201 and an inclined section 202 , and the inclined section 202 is arranged to be inclined downward from the cleaning seat 1 toward the contact surface 201 .

[0039] Specifically, the design of the inclined section 202 enables the cleaning teeth 2 to contact the abrasive more effectively. This inclination can help the cleaning teeth 2 operate at a more appropriate angle in the grinding component 5, optimize the agitation and cleaning of the abrasive, help guide the abrasive to the outlet or the next processing stage, and reduce the residence time of the material in the cleaning seat 1; the contact surface 201 provides a wide contact area, which helps to thoroughly remove residues adhering to the inside of the grinding component 5.

[0040] Further, if Figure 5 As shown, the cleaning tooth 2 comprises a first guiding inclined surface 203 , and an inclined angle a is provided between the first guiding inclined surface 203 and the cleaning seat 1 , wherein 80°≤a≤120°.

[0041] Specifically, the design of the first guide slope 203 enables the cleaning teeth 2 to contact the abrasive, increasing the contact area and force, thereby improving the cleaning efficiency and effect. The set inclined angle a enables the cleaning teeth 2 to more effectively guide the material to move in a predetermined direction when pushing the abrasive, especially for the abrasive flowing downward or toward the outlet, which helps to reduce blockage and improve the processing speed.

[0042] The angle range of the set tilt angle a allows the cleaning teeth 2 to effectively clean different areas of the grinding assembly 5, especially those corners and gaps where abrasives are easily accumulated.

[0043] Preferably, the tilt angle a includes 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, or 120°. The angle of the tilt angle a can be adjusted according to the fineness of the grinding and the required grinding speed. A larger angle is suitable for fast and rough grinding, while a smaller angle is conducive to a delicate and slow grinding process. It can be adjusted according to the specific needs of the user or different types of coffee beans to optimize the cleaning effect and grinding efficiency.

[0044] Further, if Figure 5 As shown, the cleaning tooth 2 further includes a second guiding inclined surface 204 , and an inclined angle b is provided between the second guiding inclined surface 204 and the cleaning seat 1 , 100°≤b≤160°; the first guiding inclined surface 203 is aligned with the second guiding inclined surface 204 .

[0045] Specifically, the second guide bevel 204 helps to stir and push the abrasive more effectively during the grinding process, ensuring more uniform grinding. The inclined angle b can promote the downward flow of the abrasive in the grinding component 5 to avoid blockage; the first guide bevel 203 and the second guide bevel 204 are aligned and arranged to complement each other and work together on the abrasive during the grinding process to improve the overall grinding and cleaning efficiency.

[0046] Preferably, the inclination angle b comprises 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, or 160°.

[0047] Further, if Figure 5 As shown, the length dimension of the cleaning tooth 2 is c, 2mm≤c≤15mm.

[0048] Specifically, the length dimension c of the cleaning teeth 2 can be more finely adapted to the internal structure and cleaning requirements of the coffee machine, which helps to ensure that the cleaning teeth 2 can properly contact the ground material and clean the ground material in the grinding assembly 5 .

[0049] Preferably, the length dimension c of the cleaning teeth 2 comprises 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm.

[0050] Furthermore, the cleaning tooth 2 further includes a side surface 205 , and the side surface 205 is in the same horizontal plane as the outer circumferential surface of the cleaning base 1 .

[0051] Specifically, the alignment design of the side surface 205 of the cleaning tooth 2 and the outer surface of the cleaning seat 1 is not only more beautiful and neat in appearance, but also may reduce the possibility of abrasives and other residues accumulating in the structural gaps during cleaning, making it easier to clean and maintain; and it helps to ensure accurate alignment of components during production, reducing manufacturing tolerances and complexity.

[0052] Further, if Figure 3 and Figure 6 As shown, the cleaning tooth 2 further includes a connecting surface 206 , which is located on the inner side of the cleaning tooth 2 , and the connecting surface 206 is inclined inward from top to bottom from the cleaning seat 1 .

[0053] Specifically, the connection surface 206 located on the inner side of the cleaning teeth 2 and tilted inward from the cleaning seat 1 from top to bottom is a design that further optimizes the cleaning function and structural strength. This inwardly tilted connection surface 206 helps guide the material and improve the cleaning efficiency.

[0054] Further, if Figure 6 As shown, an included angle d is provided between the second guiding inclined surface 204 and the connecting surface 206, and 100°≤d≤180°.

[0055] Specifically, the angle d helps to effectively push and guide the abrasive, promoting in-depth cleaning action; a larger angle may help push the material downward or outward, while a smaller angle may be more suitable for finely controlling the flow of the material.

[0056] Preferably, the angle d comprises 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, or 180°.

[0057] Specifically, the cleaning teeth 2 are cone-shaped; the cleaning teeth 2 and the cleaning seat 1 are an integrally formed structure or a separately formed structure.

[0058] Specifically, the cone-shaped cleaning teeth 2 have a guiding function, allowing the coffee beans to flow in the direction of the grinding assembly 5, which can assist in grinding the coffee beans and promote a more uniform particle size distribution.

[0059] Furthermore, the cleaning teeth 2 and the cleaning seat 1 can be an integrally formed structure or a split-formed structure. When the cleaning teeth 2 and the cleaning seat 1 are an integrally formed structure, the cleaning teeth 2 and the cleaning seat 1 are processed at the same time, and there is no need to connect the cleaning teeth 2 and the cleaning seat 1 during assembly, thereby simplifying the assembly steps and effectively improving the assembly efficiency; the integrally formed structure includes integral injection molding or die-casting; when the cleaning teeth 2 and the cleaning seat 1 are a split-formed structure, the cleaning teeth 2 and the cleaning seat 1 are manufactured separately, and then the two are connected and fixed by riveting, welding, screws, or snap connections, thereby reducing the manufacturing difficulty of the cleaning teeth 3011 and the cleaning seat 301.

[0060] It should be noted that the cleaning teeth 2 and the cleaning seat 1 can be made of different materials and can be integrally formed or separately formed.

[0061] like Figure 7 and Figure 8 As shown, a bean grinding coffee machine includes a body 4, on which is provided a grinding assembly 5 for grinding ground materials, and on which is also provided a cleaning structure cooperating with the grinding assembly 5, wherein the grinding assembly 5 includes a powder sweeping plate 501, and cleaning teeth 2 are cooperatively connected with the powder sweeping plate 501, and the cleaning teeth 2 are plugged into the powder sweeping plate 501.

[0062] Specifically, the coordinated design of the powder sweeping plate 501 and the cleaning teeth 2 can further improve the cleaning efficiency of the coffee machine. The powder sweeping plate 501 can drive the cleaning seat 1 to rotate when rotating. The powder sweeping plate 501 is designed to effectively collect and guide the abrasives generated during the grinding process. Together with the use of the cleaning teeth 2, the abrasive residue in the grinding chamber can be minimized. The powder sweeping plate 501 can help level the abrasives or push them to the outlet to reduce blockage. The coordinated use of the cleaning teeth 2 and the powder sweeping plate 501 not only helps with cleaning, but also optimizes the uniformity of grinding by adjusting the distribution of the abrasives, ensuring that the abrasives are more evenly distributed after passing through the grinding assembly 5, thereby improving the extraction efficiency and the quality of the final beverage.

[0063] Furthermore, the grinding assembly 5 further includes a grinding piece 502 and a motor 503 for driving the grinding piece 502 and the powder sweeping plate 501 to rotate, and the output shaft of the motor 503 is cooperatively connected with the grinding piece 502 and the powder sweeping plate 501 .
