[0050] See also Figures 1 to 11The food processor 500 includes a main unit 200, a blending cup 50 and a crushing assembly 100. The main unit 200 includes a housing 220 and a motor 210 disposed in the housing 220. The blending cup 50 is mounted on the main unit 200.

[0051] In the illustrated embodiment, the food processor 500 further includes a chassis assembly 60, which is mounted on the bottom of the blending cup 50, and the crushing assembly 100 is mounted on the chassis assembly 60. The chassis assembly 60 can be fixed to the bottom of the blending cup 50, or can be detachably mounted on the bottom of the blending cup 50.

[0052] In other embodiments, the food processor 500 may not include the chassis assembly 60 , and the blending cup 50 is provided with a bottom wall, and the crushing assembly 100 is installed on the bottom wall.

[0053] See also Figure 1 A protrusion 51 is protruding inward at the bottom end of the blending cup 50, and the chassis assembly 60 includes a chassis 61 and a bottom cover 62 fixed to the chassis 61. The chassis 61 presses against the protrusion 51 from top to bottom, and the bottom cover 62 presses against the protrusion 51 from bottom to top, thereby fixing the chassis assembly 60 to the bottom of the blending cup 50.

[0054] See also Figures 2 to 4 The crushing assembly 100 includes a grinding assembly 10 and a crushing tool 20. The grinding assembly 10 includes a rotating shaft 11, a fixed grinding piece 12 and a moving grinding piece 13. The rotating shaft 11 passes through the fixed grinding piece 12 and can rotate relative to the fixed grinding piece 12. The fixed grinding piece 12 is provided with a receiving cavity 121 and a feed port 122 communicating with the receiving cavity 121. The moving grinding piece 13 is fixed to the rotating shaft 11 and received in the receiving cavity 121. An upper clutch 119 is provided at the lower end of the rotating shaft 11 for connecting with a lower clutch of a motor 210. The crushing tool 20 is mounted on the moving grinding piece 13. The crushing tool 20 includes a blade 21. The blade 21 can be switched between at least a first state and a second state, and the end of the blade 21 is closer to the fixed grinding piece 12 in the second state than in the first state.

[0055] In the food processor 500 of the present application, when the crushing component 100 crushes the food, the crushing cutter 20 first performs a preliminary crushing step on the large pieces of food, and when the food is cut and reduced in volume, it enters the grinding component 10 for a fine crushing step. In this way, the motor does not need to provide a high speed to fully grind the food, the working noise is low, and the crushing effect is good. At the same time, the blade 21 performs preliminary crushing on the food in the first state, and when the preliminary crushing is completed, the blade 21 switches to the second state. Since the end of the blade 21 is closer to the fixed grinding part 12 in the second state than in the first state, the food can enter the receiving chamber 121 more quickly and fully through the feed port 122 without blocking the food, thereby achieving a better crushing effect and higher efficiency.

[0056] The speed of the motor 210 ranges from 6000 rpm to 8000 rpm. Thus, the motor 210 produces little noise during operation. In some embodiments, the speed of the motor 210 can be 6000 rpm, 6500 rpm, 7000 rpm, 7500 rpm, 8000 rpm, or a value between any two of the above.

[0057] In the illustrated embodiment, the blade 21 is arranged to be rotatable relative to the movable grinding member 13. When the motor 210 drives the movable grinding member 13 to rotate in the forward direction, the blade 21 is in the first state (see Figure 5 ), when the motor 210 drives the movable grinding member 13 to rotate in the reverse direction, the blade 21 rotates to the second state (see Figure 6 ). The positive rotation may be clockwise or counterclockwise, and the reverse rotation is opposite to the positive rotation. In this way, when the moving grinding member 13 rotates in different directions, the blade 21 can automatically switch between the first state and the second state, which is convenient for use. In other embodiments, the blade 21 is arranged in a manner that it can be extended or moved relative to the moving grinding member 13.

[0058] In the illustrated embodiment, the angle that the blade 21 needs to rotate when switching between the first state and the second state is between 30 degrees and 120 degrees. In this way, the blade 21 can be more effectively close to the fixed grinding member 12 in the second state, so that the food that has been initially crushed by the blade 21 can enter the receiving chamber 121 more quickly, thereby further ensuring the crushing effect and efficiency. The angle that the blade 21 needs to rotate when switching between the first state and the second state can be 30 degrees, 50 degrees, 70 degrees, 90 degrees, 110 degrees, 120 degrees, or a value between any two adjacent ones of the above.

[0059] The crushing tool 20 further includes a tool holder 22 connected to the dynamic grinding part 13, and the blade 21 is rotatably mounted on the tool holder 22. In this way, the crushing tool 20 is more convenient to install. The tool holder 22 can be fixed to the dynamic grinding part 13 by fasteners such as screws, or by riveting, welding, etc.

[0060] The blade holder 22 includes a main body 221 mounted in cooperation with the dynamic grinding member 13 and a mounting portion 222 for mounting the blade 21. The mounting portion 222 is provided with a limiting portion 223. When the dynamic grinding member 13 rotates forward, the limiting portion 223 limits the blade 21 to a first state. Specifically, the limiting portion 223 is protruding upward from the mounting portion 222, and the limiting portion 223 blocks one side of the blade 21. In this way, the blade 21 is limited by setting the limiting portion 223, which has a simple structure and is easy to use. When the dynamic grinding member 13 rotates forward, the limiting portion 223 limits the blade 21 to a first state; when the dynamic grinding member 13 rotates reversely, the blade 21 automatically rotates to a second state.

[0061] In the illustrated embodiment, the mounting portion 222 is provided with a through hole, the limiting nut 227 passes through the through hole and is fixed with the limiting screw 226, the blade 21 is sleeved on the limiting nut 227, and the blade 21 is limited by the limiting head of the limiting screw 226. Of course, in other embodiments, the blade 21 can also be rotatably mounted on the mounting portion 222 through other structures, which are not listed here one by one.

[0062] The blade holder 22 further includes a connecting portion 224 connecting the main body 221 and the mounting portion 222, the connecting portion 224 extending in the up-down direction, and the mounting portion 222 being lower than the main body 221. Thus, by providing the connecting portion 224, the mounting portion 222 is lower than the main body 221, so that the blade 21 can crush the food at the bottom of the mixing cup 50, and the crushing effect is good.

[0063] The distance between the blade 21 and the chassis assembly 60 ranges from 20 mm to 45 mm. In other words, the distance between the blade 21 and the chassis 61 ranges from 20 mm to 45 mm. In this way, the blade 21 can effectively crush the ingredients at the bottom of the mixing cup 50, with a better crushing effect, and the distance between the blade 21 and the chassis 61 is sufficient so that no collision occurs during operation. The distance between the blade 21 and the chassis 61 can be 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, or a value between any two adjacent ones of the above.

[0064] In addition, when the movable grinding member 13 rotates in the reverse direction, the connecting portion 224 blocks the blade 21, thereby limiting the blade 21 to the second state. In this way, the setting of the connecting portion 224 can also prevent the blade 21 from colliding with the fixed grinding member 12 during operation.

[0065] In the illustrated embodiment, the blade holder 22 includes two connecting portions 224 extending downward from opposite ends of the body portion 221, and two mounting portions 222 extending outward from the lower ends of the two connecting portions 224. In this way, the two blades 21 are respectively arranged on the two mounting portions 222, the crushing efficiency is higher, and the blade holder 22 has better balance during operation. In other embodiments, the number of the connecting portions 224 and the mounting portions 222 can be determined as needed.

[0066] See also Figure 8 The blade 21 includes an assembly portion 211 mounted in cooperation with the mounting portion 222 and a blade body 212 connected to the assembly portion 211, and the blade body 212 is provided with a spoiler hole 2121. By providing the spoiler hole 2121, the blade 21 has a better spoiler effect during rotation. In addition, the blade body 212 extends obliquely, so that the blade 21 has a larger contact area with the food during rotation, thereby having a better crushing effect and crushing efficiency.

[0067] The height of the blade 21 is not lower than the top of the feed opening 122. Thus, when the motor 210 drives the movable grinding element 13 to start reverse rotation, the blade 21 will not block or partially block the feed opening 122 during rotation, thereby ensuring that the food can enter the receiving chamber 121 through the feed opening 122 more quickly.

[0068] The fixed grinding member 12 includes a first grinding tooth 123, and the movable grinding member 13 includes a second rough grinding tooth 132 and a second fine grinding tooth 131 that cooperate with the first grinding tooth 123. The second rough grinding tooth 132 is located below the second fine grinding tooth 131, and the position of the feed port 122 on the fixed grinding member 12 corresponds to the second rough grinding tooth 132. In this way, after the food enters the receiving chamber 121 through the feed port 122, it is firstly rough ground by the second rough grinding tooth 132, and then finely ground by the second fine grinding tooth 131. The two steps of rough grinding and fine grinding can achieve a better grinding effect. The second rough grinding tooth 132 is in a spiral ascending shape, and the second fine grinding tooth 131 is in a vertical tooth shape. During the rotation of the movable grinding member 13, when the food is ground between the second rough grinding tooth 132 and the first grinding tooth 123, the second rough grinding tooth 132 can lift the food upward and transport it in the direction of the second fine grinding tooth 131.

[0069] The first grinding teeth 123 include a first coarse grinding tooth 1231 corresponding to the second coarse grinding tooth 132 and a first fine grinding tooth 1232 corresponding to the second fine grinding tooth 131. In this way, the grinding effect of the food is further guaranteed. The second coarse grinding teeth 132 and the second fine grinding teeth 131 both extend in the up-down direction and are arranged in the circumferential direction. The arrangement density of the second fine grinding teeth 131 is greater than the arrangement density of the second coarse grinding teeth 132.

[0070] The top of the fixed grinding member 12 is open, and a discharge port 124 is formed between the top of the fixed grinding member 12 and the movable grinding member 13. After the food is coarsely ground and finely ground, it is discharged through the discharge port 124.

[0071] The movable abrasive component 13 is installed in the receiving cavity 121 from top to bottom, and the pulverizing assembly 100 further includes a stopper 30 installed in cooperation with the top end of the rotating shaft 11, and the stopper 30 is used to limit the movable abrasive component 13 in the up and down directions. Thus, by providing the stopper 30, the movable abrasive component 13 can be prevented from moving up and down along the rotating shaft 11, thereby making the pulverizing assembly 100 more stable during operation.

[0072] The limiting member 30 is provided with a first magnetic element 32, the dynamic grinding member 13 is provided with a second magnetic element 135 corresponding to the first magnetic element 32, and the rotating shaft 11 is provided with a limiting groove 111. Through the magnetic force between the first magnetic element 32 and the second magnetic element 135, the limiting member 30 is inserted into the limiting groove 111, thereby limiting the dynamic grinding member 13. In this way, through the magnetic force between the first magnetic element 32 and the second magnetic element 135, the limiting member 30 is inserted into the limiting groove 111, and the installation and disassembly are more convenient. In this way, according to specific use needs, different dynamic grinding members 13 and crushing knives 20 can be easily replaced, so that the food processor 500 has multiple functions.

[0073] The first magnetic element 32 and the second magnetic element 135 are ring-shaped with the same radial size; the first magnetic element 32 is eccentrically arranged on the stopper 30, or the second magnetic element 51 is eccentrically arranged on the movable grinding part 13. In this way, when the stopper 30 is sleeved on the rotating shaft 11, the magnetic force between the first magnetic element 32 and the second magnetic element 135 can make the stopper 30 slide a certain distance in the horizontal direction, so that the first magnetic element 32 and the second magnetic element 135 are aligned, and at this time, the stopper 30 is stuck in the stopper groove 111.

[0074] The stopper 30 includes an upper shell 33 and a lower shell 34 mounted together with the upper shell 33, and the first magnetic element 32 is arranged between the upper shell 33 and the lower shell 34. In this way, the structure is simple and easy to disassemble and assemble. In the illustrated embodiment, the upper shell 33 and the lower shell 34 are connected by threads, but it is not limited thereto. The upper shell 33 or the lower shell 34 is provided with a stopper protrusion 131 that is matched with the stopper groove 111.

[0075] The first magnetic element 32 is a permanent magnet, and the second magnetic element 135 is a permanent magnet, metal iron or soft magnetic steel; or, the first magnetic element 32 is metal iron or soft magnetic steel, and the second magnetic element 135 is a permanent magnet. In the illustrated embodiment, both the first magnetic element 32 and the second magnetic element 135 are permanent magnets.

[0076] The pulverizing assembly 100 further includes a sleeve 40 sleeved on the rotating shaft 11 , a bearing 41 is disposed between the sleeve 40 and the rotating shaft 11 , and the fixed wear member 12 is fixed to the sleeve 40 .

[0077] The shaft sleeve 40 of the crushing assembly 100 passes through the chassis assembly 60, and the shaft sleeve 40 is pressed downward on the chassis assembly 60. The crushing assembly 100 also includes a mounting sleeve 70 that is pressed upward on the chassis assembly 60. The mounting sleeve 70 cooperates and locks with the shaft sleeve 40 to install the crushing assembly 100 on the chassis assembly 60. In this way, in use, different crushing assemblies 100 can be replaced as needed to achieve multiple functions. In the illustrated embodiment, the mounting sleeve 70 and the shaft sleeve 40 are locked by a threaded structure. In other embodiments, the mounting sleeve 70 and the shaft sleeve 40 can also be locked by other means such as buckles.
