Therefore, they should not be construed as limitations on this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0049] Please refer to the following: Figures 1 to 8 The feeding mechanism provided in the embodiments of this application will now be described. The feeding mechanism includes a housing 10, a cutter 20, and a stop protrusion 114. The housing 10 has a crushing chamber 101, a feed inlet 102, and a discharge outlet 103. The feed inlet 102 communicates with the top of the crushing chamber 101, and the discharge outlet 103 communicates with the bottom of the crushing chamber 101. The cutter 20 is used to cut food, and the cutter 20 is rotatably mounted in the crushing chamber 101. The stop protrusion 114 is used to prevent the food from rotating when the cutter 20 cuts the food. The stop protrusion 114 is provided in the housing 10, located on the upper side of the cutter 20, and extends from the inner wall of the crushing chamber 101 toward a direction close to the rotation axis of the cutter 20. By employing the baffle 114, after the food enters the crushing chamber 101 through the feed inlet 102, the cutter 20 rotates and can cut the food. When the cutter 20 cuts the food, the baffle 114 extends toward the center of the crushing chamber 101, which can prevent the food from rotating around the rotation axis of the cutter 20, thereby improving the cutting efficiency of the cutter 20 on the food.

[0050] In one embodiment of this application, please refer to Figures 2 to 7The housing 10 has a protrusion 111 inside. The protrusion 111 is used to prevent the food from sliding along the inner wall of the crushing chamber 101 when the cutter 20 is cutting the food. The protrusion 111 intersects with the rotation plane of the cutter 20, that is, the protrusion 111 is not parallel to the rotation plane of the cutter 20. After the food enters the crushing chamber 101, the cutter 20 rotates and cuts the food into small pieces. When the cutter 20 rotates, large pieces of food are pushed to the inner wall of the housing 10. At this time, the protrusion 111 can prevent the large pieces of food from sliding along the inner wall of the crushing chamber 101, so that the cutter 20 can chop the large pieces of food and improve the cutting efficiency of the cutter 20. Moreover, the protrusion 111 can increase the structural strength of the housing 10 and prevent the large pieces of food from hitting the inner wall of the housing 10 when the cutter 20 pushes them to move towards the inner wall of the housing 10, which would cause the housing 10 to deform or be damaged. After the food collidees with the protrusion 111, the side of the food that is close to the inner wall of the crushing chamber 101 will slow down and deflect at an angle, thereby weakening the impact of the food colliding with the baffle 114 and protecting the baffle 114.

[0051] In one embodiment of this application, please refer to Figures 2 to 7 The cutter 20 has multiple ridges 111 arranged around its rotation axis. These ridges enhance the structural strength of the housing 10, improve the cutting efficiency of the cutter 20, ensure uniform strength of the housing 10, maintain consistent cutting efficiency across all areas, and reduce vibration and noise during operation. The ridges 111 can, but are not limited to, be arranged in a ring array.

[0052] In one embodiment of this application, please refer to Figures 2 to 7 The distance between adjacent protrusions 111 is 5mm-50mm. Optionally, the distance between adjacent protrusions 111 can be 10mm, 20mm, 30mm or 40mm, etc. By controlling the distance between adjacent protrusions 111, the structural strength distribution of the shell 10 can be ensured to be uniform, and it is convenient to clean the crushing chamber 101 to prevent food residue from remaining between adjacent protrusions 111.

[0053] In one embodiment of this application, please refer to Figures 2 to 7 The height of the protrusion 111 is 0.5mm-10mm. Optionally, the height of the protrusion 111 is 1mm, 2mm, 4mm, or 7mm, etc. By controlling the height of the protrusion 111, the structural strength of the protrusion 111 can be ensured, preventing the protrusion 111 from breaking when impacted by food, and ensuring the protrusion 111's blocking effect on large pieces of food. The height of the protrusion 111 refers to the dimension by which the protrusion 111 protrudes from the inner wall of the housing 10 towards the rotation axis of the cutter 20.

[0054] In one embodiment of this application, please refer to Figures 2 to 7The length of the protrusion 111 is 5cm-30cm. Optionally, the length of the protrusion 111 is 10cm, 15cm, 20cm, or 25cm, etc. By controlling the length of the protrusion 111, it is possible to facilitate the contact between the food and the protrusion 111 during rotation, so as to prevent food of different heights from rotating. The length of the protrusion 111 refers to the dimension from the end of the protrusion 111 near the top of the crushing chamber 101 to the end of the protrusion 111 near the bottom of the crushing chamber 101.

[0055] In one embodiment of this application, please refer to Figures 2 to 7 The angle between the length direction of the protrusion 111 and the rotation axis of the cutter 20 is 0°-30°. Optionally, the angle between the length direction of the protrusion 111 and the rotation axis of the cutter 20 is 5°, 10°, 20°, or 25°, etc. By controlling the angle between the length direction of the protrusion 111 and the rotation axis of the cutter 20, the blocking effect of the protrusion 111 on the food when the cutter 20 cuts the food can be controlled.

[0056] In one embodiment of this application, please refer to Figures 2 to 7 The ratio of the length of the protrusion 111 to the height of the crushing chamber 101 ranges from 0.5 to 1.2. Optionally, the ratio of the length of the protrusion 111 to the height of the crushing chamber 101 ranges from 0.6, 0.75, or 1.0. By controlling the length of the protrusion 111, the stability of the inner wall of the crushing chamber 101 can be ensured, and it can play a better role in blocking the food.

[0057] In one embodiment of this application, please refer to Figures 2 to 7 The housing 10 includes a feed cylinder 11 and a cover 12. The cover 12 covers the top of the feed cylinder 11, and a protrusion 111 is provided on the inner wall of the feed cylinder 11. A connecting beam 113 connected to the cutter 20 is provided inside the feed cylinder 11. By using the connecting beam 113, the cutter 20 can be supported, and the area occupied by the bottom opening of the crushing chamber 101 can be increased, which is conducive to the discharge of the cut material from the bottom opening of the crushing chamber 101. Moreover, this facilitates the processing of the housing 10 and makes it easier to clean the crushing chamber 101.

[0058] In one embodiment of this application, please refer to Figures 2 to 7 The feeding cylinder 11 has a discharge section 112 at the end away from the cover 12. A connecting beam 113 is connected to the discharge section 112. The cross-sectional area of ​​the inner cavity of the discharge section 112 gradually decreases from the top to the bottom of the feeding cylinder 11. Optionally, the inner cavity of the discharge section 112 can be inverted conical. This can enhance the structural strength of the bottom of the feeding cylinder 11 and facilitate the collection of chopped food inside the feeding cylinder 11.

[0059] In one embodiment of this application, please refer to Figures 2 to 7The upper end of the protrusion 111 extends to the cover 12, and the lower end of the protrusion 111 is connected to the discharge section 112. This can enhance the structural strength of the part where the lower end of the feed cylinder 11 is connected to the discharge section 112 and prevent the lower end of the protrusion 111 from breaking due to impact from food.

[0060] In one embodiment of this application, please refer to Figures 2 to 6 The cover 12 includes a cover plate 121 and a protruding ring 122. The protruding ring 122 is located on the side of the cover plate 121 near the crushing chamber 101 and is inserted into the feed cylinder 11. This improves the stability of the cover 12 when it covers the feed cylinder 11 and prevents the cover 12 from separating from the feed cylinder 11 when the cutter 20 is cutting the food.

[0061] In one embodiment of this application, please refer to Figures 2 to 6 The cover 12 also includes a guide section 123 located at the end of the protruding ring 122 away from the cover plate 121. The outer diameter of the guide section 123 is smaller than the outer diameter of the protruding ring 122. The guide section 123 guides the protruding ring 122 into the feed cylinder 11, facilitating the cover 12 to close onto the feed cylinder 11. Optionally, the outer diameter of the guide section 123 near the cover plate 121 gradually increases towards the cover plate 121. This allows the protruding ring 122 to be guided into the opening at the top of the feed cylinder 11.

[0062] In one embodiment of this application, please refer to Figures 2 to 7 The protruding strip 111 extends from one end near the cover plate 121 to the end of the guide section 123 near the protruding ring 122, and engages to hold the guide section 123. This improves the stability of the cover 12 when it covers the top of the feed cylinder 11. Optionally, multiple protruding strips 111 are arranged around the guide section 123, which improves the structural strength of the cover 12 after it is closed with the top of the feed cylinder 11, preventing the feed cylinder 11 from deforming during the operation of the cutter 20.

[0063] Optionally, the difference between the opening radius at the top of the feed cylinder 11 and the opening radius at the bottom of the feed cylinder 11 is greater than the height of the ridge 111. This reduces the amount of food residue remaining between the ridges 111.

[0064] In one embodiment of this application, please refer to Figures 2 to 7The top of the retaining protrusion 114 is provided with cutting teeth 115, which are located on the feeding side of the retaining protrusion 114. The feeding side of the retaining protrusion 114 refers to the side of the cutter 20 with the linear velocity opposite to that of the position near the retaining protrusion 114 when the cutter 20 rotates and cuts the food. That is, when the cutter 20 approaches the retaining protrusion 114, it approaches from the feeding side and then moves away from the discharging side. When the food rotates around the rotation axis of the cutter 20 to the feeding side of the retaining protrusion 114, the cutting teeth 115 are directly facing the food, easily penetrating it and restricting its movement. By providing cutting teeth 115 on the feeding side of the retaining protrusion 114, the slippage of the food after contact with the retaining protrusion 114 can be reduced, thereby significantly improving the cutting effect. The top of the retaining protrusion 114 refers to the end of the retaining protrusion 114 closest to the rotation axis of the cutter 20.

[0065] In one embodiment of this application, please refer to Figures 2 to 7 The cutting teeth 115 have a cutting edge 1151 formed at their top, which works in conjunction with the cutter 20 to cut the food. By sharpening the top of the cutting teeth 115, the cutting edge 1151 helps the cutting teeth 115 pierce the food, thus improving the cutting effect of both the cutting teeth 115 and the cutter 20. The top of the cutting teeth 115 refers to the end of the cutting teeth 115 away from the discharge side of the stop protrusion 114, and the bottom of the cutting teeth 115 refers to the end of the cutting teeth 115 connected to the stop protrusion 114. Optionally, the cutting edge 1151 is located on the side of the stop protrusion 114 closer to the cutter 20. In this way, when the cutter 20 pushes the food to rotate, the food is more likely to collide with the cutting teeth 115.

[0066] In one embodiment of this application, please refer to Figures 2 to 7 The distance between the cutting teeth 115 and the rotation plane of the cutter 20 is less than the distance between the top of the stop protrusion 114 and the rotation plane of the cutter 20. This makes the cutting teeth 115 located on the side of the top of the stop protrusion 114 closer to the cutter 20, so that when the cutter 20 pushes the food to rotate, the food is more likely to collide with the cutting teeth 115.

[0067] In one embodiment of this application, please refer to Figures 2 to 7 The cutting tooth 115 has a first side surface 1152 on the side away from the cutter 20. The first side surface 1152 slopes from the bottom to the top of the cutting tooth 115 towards the direction closer to the cutter 20. The cutting tooth 115 has a second side surface 1153 on the side closer to the cutter 20, and the second side surface 1153 intersects with the first side surface 1152. That is, the first side surface 1152 is located on the upper side of the cutting tooth 115, and the second side surface 1153 is located on the lower side of the cutting tooth 115. The first side surface 1152 and the second side surface 1153 are not parallel. This design makes the top area of ​​the cutting tooth 115 small and sharp, making it easier to pierce food.

[0068] In one embodiment of this application, please refer to Figures 2 to 7 The angle between the first side surface 1152 and the rotation axis of the cutter 20 is 10°-60°. Optionally, the angle between the first side surface 1152 and the rotation axis of the cutter 20 is 20°, 30°, 40°, or 50°, etc. This makes the angle between the first side surface 1152 and the horizontal direction larger, which facilitates the food to slide downwards and fall off the cutting teeth 115 after the cutting teeth 115 penetrates the food, preventing the cutting teeth 115 from catching the food and causing the food to suspend in the air.

[0069] In one embodiment of this application, please refer to Figures 2 to 7 The angle between the second side 1153 and the first side 1152 is 30°-80°. Optionally, the angle between the second side 1153 and the first side 1152 is 40°, 50°, 60°, or 70°. By controlling the angle between the second side 1153 and the first side 1152, the depth to which the cutting teeth 115 pierce the food can be controlled, and the tip of the cutting teeth 115 can be prevented from being too sharp, facilitating the separation of the food from the cutting teeth 115.

[0070] In one embodiment of this application, please refer to Figures 2 to 7 The height of the cutting teeth 115 ranges from 0.5mm to 5mm. Optionally, the height of the cutting teeth 115 can be 1mm, 2mm, 3mm, or 4mm, etc. By controlling the height of the cutting teeth 115, the structural strength of the cutting teeth 115 and the piercing effect of the cutting teeth 115 can be guaranteed. The height direction of the cutting teeth 115 can be understood as... Figure 2 The direction of the vertical cutting plane.

[0071] In one embodiment of this application, please refer to Figures 2 to 7 The width of the cutting tooth 115 ranges from 1mm to 5mm. Optionally, the width of the cutting tooth 115 can be 1.5mm, 2mm, 3mm, or 4mm, etc. By controlling the width of the cutting tooth 115, the stability of the connection between the cutting tooth 115 and the stop protrusion 114 can be ensured. The width direction of the cutting tooth 115 can be understood as the dimension of the cutting tooth 115 along the rotation axis of the cutter 20.

[0072] In one embodiment of this application, please refer to Figures 2 to 7 The length of the cutting tooth 115 ranges from 1mm to 8mm. Optionally, the length of the cutting tooth 115 can be 2mm, 4mm, 6mm, or 7mm, etc. By controlling the length of the cutting tooth 115, the cutting length of the cutting tooth 115 can be guaranteed, and the stability of the connection between the cutting tooth 115 and the stop protrusion 114 can be improved. The length of the cutting tooth 115 can be understood as the dimension of the cutting tooth 115 along the height direction of the stop protrusion 114.

[0073] In one embodiment of this application, please refer to Figures 2 to 7 The side of the retaining protrusion 114 away from the cutter 20 has a first inclined surface 1141, which slopes from the bottom to the top of the retaining protrusion 114 towards the direction closer to the cutter 20. This allows food on the upper side of the retaining protrusion 114 to slide down easily. In this embodiment, the side of the retaining protrusion 114 near the cutter 20 has a second inclined surface 1142, which slopes from the bottom to the top of the retaining protrusion 114 away from the cutter 20. This increases the stability of the retaining protrusion 114.

[0074] In one embodiment of this application, please refer to Figures 2 to 7 The inclination angle of the first inclined surface 1141 is 40°-80°. Optionally, the inclination angle of the first inclined surface 1141 is 45°, 50°, 60° or 70°, etc. This allows the food above the first inclined surface 1141 to slide down easily.

[0075] In one embodiment of this application, please refer to Figures 2 to 6 The inclination angle of the second inclined plane 1142 is 1°-20°. Optionally, the inclination angle of the second inclined plane 1142 is 3°, 8°, 12° or 16°, etc. This helps to restrict the upward movement of the food.

[0076] In one embodiment of this application, please refer to Figures 2 to 7 The height of the bulge 114 (e.g.) Figure 5 The horizontal dimension of the center baffle 114 is 10mm-45mm. Optionally, the height of the baffle 114 is 15mm, 20mm, 30mm or 40mm. This increases the probability of the food colliding with the baffle 114 and prevents the baffle 114 from affecting the food's descent.

[0077] In one embodiment of this application, please refer to Figures 2 to 7 The stop protrusion 114 and the cutter 20 are along the rotation axis of the cutter 20 (e.g., Figure 5 The vertical distance between the baffle 114 and the cutter 20 (in the vertical direction) is 5mm-65mm. Optionally, the vertical distance between the baffle 114 and the cutter 20 along the rotation axis of the cutter 20 is 10mm, 20mm, 30mm or 45mm. This prevents the baffle 114 from colliding with the cutter 20 and effectively blocks large pieces of food from rotating.

[0078] In one embodiment of this application, please refer to Figures 2 to 7The ratio of the height of the baffle 114 to the radius of the crushing chamber 101 ranges from 0.2 to 0.8. Optionally, the ratio of the height of the baffle 114 to the radius of the crushing chamber 101 is 0.3, 0.5, or 0.6. This prevents the baffle 114 from obstructing the descent of the food and also prevents the food from rotating. The height of the baffle 114 can be understood as the vertical distance between the end of the baffle 114 closest to the rotation axis of the cutter 20 and the end of the baffle 114 furthest from the rotation axis of the cutter 20; the radius of the crushing chamber 101 can be understood as the vertical distance between the rotation axis of the cutter 20 and the inner wall of the crushing chamber 101.

[0079] In one embodiment of this application, please refer to Figures 2 to 7 The ratio of the width of the baffle 114 to the width of the rib 111 ranges from 1.5 to 10. Optionally, the ratio can be 2, 3.5, 6, or 8. This enhances the structural strength of the baffle 114 and prevents it from breaking when impacted by large pieces of food. The width of the baffle 114 can be understood as the distance between the sides of the baffle 114 closest to two adjacent ribs 111.

[0080] In one embodiment of this application, please refer to Figures 2 to 7 The length of the baffle 114 gradually decreases from its bottom to its top. This makes the top of the baffle 114 gradually become sharper, resulting in less resistance when food impacts it and making it easier to break the food. The length of the baffle 114 can be understood as... Figure 5 The vertical dimension of the center section protrusion 114.

[0081] In one embodiment of this application, please refer to Figures 2 to 7 The width of the baffle 114 gradually decreases from the bottom to the top. This makes the top of the baffle 114 gradually become sharper, resulting in less resistance when food is impacted and making it easier to break the food.

[0082] In one embodiment of this application, please refer to Figures 2 to 7 A first chamfer structure 1143 is provided between the top surface of the retaining protrusion 114 and the first inclined surface 1141. The top surface of the retaining protrusion 114 refers to the surface at the top of the retaining protrusion 114 that is away from the bottom of the retaining protrusion 114. The first chamfer structure 1143 can be a rounded corner or a bevel. By adopting the first chamfer structure 1143, it is possible to facilitate the falling of food along the retaining protrusion 114, and it is also beneficial to reduce the wear on the top of the retaining protrusion 114 and prevent the top of the retaining protrusion 114 from breaking.

[0083] In one embodiment of this application, please refer to Figures 2 to 7A second chamfer structure 1144 is provided between the top surface of the retaining protrusion 114 and the second inclined surface 1142. The second chamfer structure 1144 can be a rounded corner or a bevel. By adopting the second chamfer structure 1144, the impact of food hitting the top of the retaining protrusion 114 can be reduced, the wear of the retaining protrusion 114 can be reduced, and the top of the retaining protrusion 114 can be prevented from breaking.

[0084] In one embodiment of this application, please refer to Figures 2 to 7 The crushing chamber 101 is provided with a boss 116, and the protrusions 111 are arranged along the height direction of the crushing chamber 101. The baffle 114 is provided on the boss 116. By providing the boss 116, it is beneficial to reduce the height of the baffle 114, enhance the structural strength of the connection between the baffle 114 and the shell 10, and prevent the baffle 114 from breaking.

[0085] In one embodiment of this application, please refer to Figures 2 to 7 A reinforcing rib 117 is provided inside the crushing chamber 101. One end of the reinforcing rib 117 is connected to the stop protrusion 114, and the other end of the reinforcing rib 117 extends to the lower side of the cutter 20. By providing the reinforcing rib 117, the structural strength of the connection between the housing 10 and the stop protrusion 114 can be increased, preventing deformation or damage to the part of the housing 10 near the stop protrusion 114.

[0086] In one embodiment of this application, please refer to Figures 2 to 8 The feeding mechanism also includes a bearing housing 13 and a support shaft 14. The bearing housing 13 is mounted on the connecting beam 113, and the support shaft 14 is rotatably mounted on the bearing housing 13. The support shaft 14 is connected to the cutter 20. Thus, the cutter 20 can be rotatably mounted at the bottom of the housing 10. After the food enters the crushing chamber 101, it can automatically fall onto the cutter 20. When the cutter 20 rotates, it can chop the food and discharge it through the discharge section 112. Optionally, the top of the crushing chamber 101 is open, thus facilitating the feeding of food into the crushing chamber 101.

[0087] In one embodiment of this application, please refer to Figures 2 to 8 The cutter 20 includes a blade plate 21 and a connecting plate 23. The blade plate 21 is connected to the support shaft 14. A first cutting edge 22 is provided on one side of the blade plate 21. The connecting plate 23 is formed by bending the side of the blade plate 21 away from the first cutting edge 22 towards the connecting beam 113. A second cutting edge 24 is provided on the side of the connecting plate 23 away from the blade plate 21. This allows two cutting zones to be formed along the height direction through the first cutting edge 22 and the second cutting edge 24, and the connecting plate 23 can push large pieces of food to move, improving the cutting efficiency of the food.

[0088] Please see Figures 1 to 8 This application also provides a juicer, including the feeding mechanism described in any of the above embodiments. By employing the feeding mechanism described in the above embodiments, the efficiency of food cutting can be improved.
