[0036] Specifically, the cleaning component 3 can be easily installed on the grinding component 1 and can be disassembled and cleaned at any time during use, ensuring the cleanliness of the inside of the grinding component 2; the hard cleaning teeth 3011 on the cleaning seat 301 cooperate with the grinding component 2, and the hard cleaning teeth 3011 can push and clean the grinding material during the cleaning process, thereby avoiding unevenness and residue of the grinding material, which not only helps to maintain the hygiene inside the equipment, but also improves the taste and quality of the extraction, and the cleaning teeth 3011 can push the grinding material inside the grinding component 2 downward, which can make the coffee powder grind more evenly, and thus make the ground grinding material more delicate and uniform.

[0037] Selecting durable and non-damageable hard cleaning teeth 3011 can, on the one hand, extend the service life of the cleaning component 3; on the other hand, it can keep the inside of the grinding component 2 clean and avoid residue; the hard cleaning teeth 3011 can be made of high-strength stainless steel or plastic with a specific hardness.

[0038] Specifically, the elastic reset member 303 enables the push member 302 to automatically adjust its pressure according to the capacity of the ground material. The pressure is increased when there is more ground material, and the pressure is reduced as the ground material is consumed. The elastic reset member 303 can automatically adjust to ensure that the push member 302 always maintains an appropriate position and pressure, which helps to maintain the grinding efficiency and quality force, ensure that the coffee beans are evenly stressed during the grinding process, and the ground coffee powder particles are more delicate and uniform, thereby improving the extraction effect of the coffee machine.

[0039] Furthermore, the ground material includes coffee beans, tea leaves, spices, or herbs, and in this embodiment, coffee beans are preferred.

[0040] Further, if Figure 2-Figure 4 As shown, the cleaning teeth 3011 are gradually inclined from top to bottom.

[0041] Specifically, the gradually inclined cleaning teeth 3011 can more effectively adapt to the shape and size of the grinding component 2. The inclined cleaning teeth 3011 can help to better push and stir the grinding material, making it easier to remove the residual grinding material; at the same time, it also helps to evenly distribute the grinding material, thereby improving the balance of extraction and the overall taste.

[0042] Further, if Figure 4 As shown, the cleaning tooth 3011 includes a first guiding inclined surface 30111 , and an inclined angle a is provided between the first guiding inclined surface 30111 and the cleaning seat 301 , wherein 80°≤a≤120°.

[0043] Specifically, the design of the first guide bevel 30111 enables the cleaning teeth 3011 to not only push and clean the coffee powder, but also effectively guide the coffee powder to move to the outlet of the grinding component 2, which helps to reduce the accumulation and residue of coffee powder and improve the thoroughness of cleaning; alternatively, the first guide bevel 30111 can guide the ground material to move toward the grinding component 2.

[0044] The angle range of the set inclination angle a allows the cleaning teeth 3011 to effectively clean different areas of the grinding assembly 2, especially those corners and gaps where coffee powder is easily accumulated.

[0045] 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.

[0046] Further, if Figure 4 As shown, the cleaning tooth 3011 includes a second guiding inclined surface 30112 , and an inclined angle b is provided between the second guiding inclined surface 30112 and the cleaning seat 301 , wherein 100°≤b≤160°.

[0047] Specifically, the second guide bevel 30112 helps to stir and push the coffee powder more effectively during the grinding process, ensuring more uniform grinding. The inclined angle b can promote the downward flow of coffee powder in the grinding assembly 2 to avoid blockage; the first guide bevel 30111 and the second guide bevel 30112 can complement each other and work together on the coffee powder during the grinding process to improve the overall grinding and cleaning efficiency.

[0048] Preferably, the inclination angle b comprises 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, or 160°.

[0049] Further, if Figure 4 As shown, the length dimension of the cleaning tooth 3011 is c, 2mm≤c≤15mm.

[0050] Specifically, the length dimension c of the cleaning teeth 3011 can be more finely adapted to the internal structure and cleaning requirements of the coffee machine, helping to ensure that the cleaning teeth 3011 can properly contact the coffee beans and clean the coffee powder in the grinding assembly 2.

[0051] Preferably, the length dimension c of the cleaning tooth 3011 includes 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.

[0052] Specifically, the cleaning tooth 3011 is in a cone shape; the cleaning tooth 3011 and the cleaning seat 301 are an integrally formed structure or a separately formed structure.

[0053] Specifically, the cone-shaped cleaning teeth 3011 have a guiding function, allowing the coffee beans to flow in the direction of the grinding component 2 path, which can assist in grinding the coffee beans and promote a more uniform particle size distribution.

[0054] Furthermore, the cleaning teeth 3011 and the cleaning seat 301 can be an integrally formed structure or a split-formed structure. When the cleaning teeth 3011 and the cleaning seat 301 are an integrally formed structure, the cleaning teeth 3011 and the cleaning seat 301 are processed at the same time, and there is no need to connect the cleaning teeth 3011 and the cleaning seat 301 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 3011 and the cleaning seat 301 are a split-formed structure, the cleaning teeth 3011 and the cleaning seat 301 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.

[0055] It should be noted that the cleaning teeth 3011 and the cleaning seat 301 can be made of different materials and can be integrally formed or separately formed.

[0056] Further, if Figure 8 and Fig. 9 As shown, a grinding assembly 2 is provided on the machine body 1, the cleaning teeth 3011 cooperate with the grinding assembly 2, and the elastic reset member 303 is compressed or released according to the abrasive capacity in the grinding assembly 2; when working, the cleaning teeth 3011 can push and clean the abrasive in the grinding assembly 2.

[0057] Further, if Figure 8 and Fig. 9 As shown, the grinding assembly 2 includes a powder sweeping plate 201 , and the cleaning teeth 3011 are cooperatively connected to the powder sweeping plate 201 .

[0058] Specifically, the coordinated design of the powder sweeping plate 102 and the cleaning teeth 3011 can further improve the cleaning efficiency of the coffee machine. The powder sweeping plate 102 can drive the cleaning seat 301 to rotate when rotating. The powder sweeping plate 201 is designed to effectively collect and guide the coffee powder generated during the grinding process. Together with the use of the cleaning teeth 3011, the residual coffee powder in the grinding chamber can be minimized. The powder sweeping plate 201 can help level the coffee powder or push it to the outlet to reduce blockage. The coordinated use of the cleaning teeth 3011 and the powder sweeping plate 102 not only helps with cleaning, but also optimizes the uniformity of grinding by adjusting the distribution of the coffee powder, thereby ensuring that the coffee powder is more evenly distributed after passing through the grinding component 2, thereby improving the extraction efficiency and the quality of the final beverage.

[0059] Furthermore, the grinding assembly 2 further includes a grinding piece 202 and a motor 203 for driving the grinding piece 202 and the powder sweeping plate 201 to rotate. The output shaft of the motor 203 is cooperatively connected with the grinding piece 202 and the powder sweeping plate 201 .

[0060] Further, if Figure 5-Figure 7 As shown, the pushing piece 302 is provided with a pushing column 3021 for pushing the abrasive, the cleaning seat 301 is provided with an annular inner cylinder 3012, and the pushing column 3021 slides up and down along the annular inner cylinder 3012; the annular inner cylinder 3012 is provided with a positioning rib 30121, and the pushing column 3021 is provided with a groove 30211 that cooperates with the positioning rib 30121.

[0061] Specifically, the pushing column 3021 slides up and down along the annular inner cylinder 3012, ensuring the effective movement of the pushing piece 302 in the grinding assembly 2 and the uniform pushing of the grinding material. The positioning rib 30121 on the annular inner cylinder 3012 cooperates with the slot 30211 on the pushing column 3021, which not only provides additional mechanical stability, but also ensures the correct alignment of the pushing column 3021 during movement to prevent displacement or jamming.

[0062] Further, if Figure 5-Figure 7 As shown, a mounting cavity 3013 is provided on the cleaning seat 301 , a supporting rib 30131 is provided in the mounting cavity 3013 , one end of the elastic reset member 303 is mounted on the mounting cavity 3013 and abuts against the supporting rib 30131 , and the other end of the elastic reset member 303 abuts against the pushing member 302 .

[0063] Specifically, the support rib 30131 provides stable structural support in the mounting cavity 3013, ensuring that the elastic return member 303 maintains the correct position and direction under pressure changes, which helps to maintain the correct operation of the push member 302 and prevent the elastic return member 303 from excessive movement or deformation; the two ends of the elastic return member 303 are respectively abutted against the support rib and the push member 302 of the mounting cavity 3013. This arrangement allows the elastic return member 303 to automatically adjust the pressure according to the amount of abrasive during the grinding process, providing an automatic adjustment mechanism to adapt to different grinding conditions.

[0064] Furthermore, the elastic reset member 303 includes elastic materials such as spring, silicone, rubber, etc.

[0065] Further, if Figure 5-Figure 7 As shown, a positioning buckle 3022 is provided on the pushing piece 302, and a step 3014 cooperating with the positioning buckle 3022 is provided on the top of the cleaning seat 301. When the pushing piece 302 moves upward, the positioning buckle 3022 cooperates with the step 3014; when the pushing piece 302 moves downward, the positioning buckle 3022 moves away from the step 3014.

[0066] Specifically, by adopting the above arrangement, the step 3014 cooperating with the positioning buckle 3022 can also ensure the stability and consistency of the cleaning seat 301 when the pushing member 302 moves.
