Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a portable food processing machine. Background Technology

[0002] Existing food processors typically include a main unit with a built-in motor and a cup body located above the motor and containing a shredder. When using the food processor, the user places the ingredients into the cup body, and the shredder rotates at high speed driven by the motor to process the ingredients. With the increasing demand for portable food processors when users are traveling, most manufacturers are producing miniaturized, portable models. For example, Chinese patent CN220212741U discloses a new type of food processor cup. This cup-shaped food processor has a lid on top, which can be fastened to the cup body to seal the grinding chamber. For added convenience, the lid includes a spout and a movable plate that can close the spout. The movable plate is pivotally connected to the lid. When the user needs to drink or process food, the movable plate can be moved to open the spout, allowing direct drinking without removing the lid from the cup body, making operation more convenient. During food processing, opening the spout allows gases generated inside the cup to escape, maintaining pressure balance and preventing the lid from being lifted due to excessive pressure. Furthermore, when carrying the food processor, the movable plate can be flipped to close the spout, ensuring a sealed container. However, after prolonged use of the movable plate, the sealing effect of the spout will be greatly reduced due to the aging of the components, causing the slurry to easily leak out of the spout when carried by the user.

[0003] In addition, the movable plate is equipped with a magnet, and the cup body is equipped with a magnetic induction switch that can be triggered by the magnet to open or close. The magnetic induction switch is electrically connected to the control circuit board. When the movable plate is opened, it approaches the magnetic induction switch, and the magnet causes the magnetic induction switch to close, thus powering on the blender. When the movable plate is closed on the spout, the magnet moves away from the magnetic induction switch, causing the magnetic induction switch to open, thus powering off the blender. However, the movable plate and the cup lid only cooperate through two protrusions. After prolonged use, the protrusions on the movable plate and the cup lid may wear out, leading to unstable or even malfunctioning positioning. Consequently, when the movable plate is opened, it may not be able to effectively approach the magnetic induction switch, causing the entire machine to malfunction and severely impacting the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a portable food processor to solve the problem that existing portable food processors, which use a spout and a movable plate that can close the spout on the cup lid for user convenience, cannot avoid the problem of unstable fit between the movable plate and the cup lid after long-term use, which leads to failure of the spout seal and failure of the magnetic induction switch.

[0005] To achieve the above objectives, this utility model provides a portable food processor, comprising a cup body with a grinding chamber and a cup lid detachably fitted onto the cup body. The cup lid includes an upper cover and a lower cover rotatably connected below the upper cover, with the upper cover covering and shielding the lower cover. A motor and a micro switch electrically connected to the motor are also provided below the cup body. A movable trigger rod is provided inside the cup body. The upper cover has a trigger part extending downward, the lower cover has an axially penetrating exhaust port, and the upper cover has an axially penetrating vent. The upper cover can rotate relative to the lower cover so that the vent and the exhaust port coincide or are misaligned to open or close the exhaust port. The upper cover and the lower cover have a mutually cooperating follower structure. After the upper cover rotates to open the exhaust port, it can continue to rotate, and through the follower structure, it drives the lower cover to rotate to fix the cup lid to the cup body and push the trigger rod downward to trigger the micro switch.

[0006] This application describes a cup lid consisting of an upper lid and a lower lid rotatably connected below the upper lid. The upper lid has a downwardly extending trigger part, the lower lid has an axially penetrating vent, and the upper lid has an axially penetrating vent. The upper lid can rotate relative to the lower lid to align or misalign the vent and the vent, thus opening or closing the vent. Specifically, when the user needs to open the vent, they rotate the upper lid to align the vent and the vent, thereby connecting the grinding chamber to the outside. When the user needs to close the vent, they rotate the upper lid to misalign the vent and the vent, thus isolating the grinding chamber from the outside. This allows the user to flexibly control the opening and closing of the vent by rotating the upper lid to meet the venting needs of different working states. For example, when processing food ingredients in a food processor, the user can rotate the upper lid to open the vent to release gases generated during the grinding and heating processes, preventing excessive pressure in the grinding chamber from causing the lid to pop up. Simultaneously, when carrying or storing food, the user can rotate the upper lid to close the vent to prevent food spillage, ensuring ease of use and safety, and improving the user experience. Compared to the existing method of opening and closing the vent through a movable plate, the upper cover rotates to make the vent and vent coincide or misalign, thus opening or closing the vent. After long-term use, the upper cover can always maintain a stable connection with the lower cover. As long as the vent and vent are misaligned, the vent can be blocked, thus maintaining a sealing effect on the cup.

[0007] Meanwhile, the upper cover covers and shields the lower cover, enhancing the seal between the two covers and preventing leakage at the connection point. This also prevents food residue from entering the gaps and causing the upper cover to get stuck or difficult to clean when rotating relative to the lower cover, ensuring long-term stability and hygiene.

[0008] Furthermore, the upper and lower lids are equipped with a cooperating follower structure. After the upper lid rotates to open the vent, it can continue to rotate, and through the follower structure, it drives the lower lid to rotate, thus fixing the lid to the cup body. This also pushes the trigger linkage downwards to activate the micro switch. When the user places the lid on the cup body, holds the upper lid, and rotates it, the upper lid rotates towards the vent under the force. When the upper lid rotates to the position where the vent and the exhaust port coincide, the exhaust port is opened. At the same time, the upper lid continues to rotate, and with the help of the follower structure, it drives the lower lid to rotate as well, until the lid is firmly locked to the cup body. Simultaneously, after the lid is fixed to the cup body, it can push the trigger lever downwards to activate the micro switch. This ensures that the lid can only push the trigger lever to activate the micro switch and start the motor to process food when the vent is open and the lid is securely fastened to the cup body. This guarantees that gas can be smoothly discharged through the vent during food processing, ensuring processing stability and preventing excessive pressure in the grinding chamber caused by processing food with the vent closed. It also prevents accidental motor start-up, improving operational safety. Furthermore, it achieves simultaneous operation of opening the vent, fixing the lid, and triggering the micro switch, simplifying user operation and improving convenience and efficiency.

[0009] In a preferred embodiment of a portable food processor, the follower structure includes an active part disposed on the upper cover and a driven part disposed on the lower cover. The active part can rotate circumferentially relative to the driven part to open or close the exhaust port of the upper cover, and after the active part rotates to abut against the driven part, it can drive the lower cover to rotate so that the cup lid is fixed or detached from the cup body.

[0010] By configuring the follower structure to include an active part on the upper cover and a driven part on the lower cover, the active part can rotate circumferentially relative to the driven part to open or close the vent on the upper cover. When the active part rotates to abut against the driven part, it can drive the lower cover to rotate so that the cup lid is fixed or detached from the cup body. That is, when the user rotates the upper cover, the active part rotates accordingly, and at this time the active part and the driven part do not abut circumferentially, so that the upper cover can rotate relative to the lower cover, thereby making the vent and the vent coincide or stagger. When the active part rotates to abut against the driven part, the active part drives the driven part to rotate together, thereby realizing the function of the upper cover driving the lower cover to rotate together, ensuring the smooth opening or closing of the vent, and at the same time, it can also realize the fixation or detachment of the upper cover driving the lower cover from the cup body.

[0011] In a preferred embodiment of a portable food processor, the active part is a drive column extending downward from the upper cover, and the driven part is a driven groove extending circumferentially from the lower cover. The drive column extends into the driven groove and abuts against both ends of the driven groove during rotation to drive the lower cover to rotate.

[0012] By using a drive column extending downward from the upper cover as the active part and a driven groove extending circumferentially from the lower cover as the driven part, the drive column extends into the driven groove, allowing it to slide within the groove as the upper cover rotates. This enables relative rotation of the upper cover relative to the lower cover, thereby opening or closing the vent. When the upper cover rotates to open or close the vent, the drive column simultaneously abuts against both ends of the driven groove. As the upper cover continues to rotate, the drive column drives the driven groove, i.e., the lower cover, to rotate as well, ensuring a tight fixation or smooth detachment of the cup lid from the cup body. This further enhances the safety and convenience of operation. Furthermore, the simple structure of the active and driven parts facilitates production and helps reduce production costs.

[0013] In a preferred embodiment of a portable food processing machine, a limiting ring rib extending circumferentially and protruding inwardly is provided at the top opening of the driven groove, and a first limiting protrusion with an enlarged outer diameter is provided at the bottom of the drive column, with the top wall of the first limiting protrusion abutting against the bottom wall of the limiting ring rib.

[0014] By providing a limiting ring rib extending circumferentially and protruding inward at the top opening of the driven groove, and a first limiting protrusion with an enlarged outer diameter at the bottom of the drive column, with the top wall of the first limiting protrusion abutting against the bottom wall of the limiting ring rib, the limiting ring rib can vertically limit the first limiting protrusion after the drive column extends into the driven groove, ensuring that the drive column is positioned within the driven groove. This achieves axial connection and fit between the entire upper and lower cover, preventing the cup lid from failing to screw into place due to unstable connection between the upper and lower cover, which could lead to separation or misalignment. Furthermore, the drive column and driven groove achieve axial connection between the upper and lower cover while simultaneously driving rotation, eliminating the need for additional structural components to connect the upper and lower cover, further simplifying the overall structure and improving product reliability.

[0015] In a preferred embodiment of a portable food processor, the lower cover includes a lower cover body with an exhaust port and a driven member fixedly connected to the upper part of the lower cover body. The driven part is formed on the driven member, and the exhaust port is formed on the lower cover body.

[0016] By setting the lower cover to include a lower cover body with an exhaust port and a driven member fixedly connected to the upper part of the lower cover body, and molding the driven part onto the driven member, the lower cover is made easier and faster to mold. This avoids the situation where the exhaust port and the driven part are molded simultaneously on the same structural component, which would make the structure complex and difficult to mold. This helps to improve product yield and production efficiency.

[0017] In a preferred embodiment of a portable food processor, the lower cover body includes a fixing part and an exhaust part that rises upward from the middle of the fixing part. The driven member is annular and sleeved on the outer periphery of the exhaust part and fixedly connected to the fixing part. The exhaust port is located on the top wall of the exhaust part.

[0018] By including a fixing part and an exhaust part that protrudes upward from the middle of the fixing part in the lower cover body, the driven member is ring-shaped and sleeved on the outer periphery of the exhaust part and fixedly connected to the fixing part, and the exhaust port is located on the top wall of the exhaust part, so that the exhaust port is relatively closer to the upper cover, thereby allowing the gas discharged from the exhaust port to be directly discharged outward through the vent, avoiding the situation where the gas is far away from the exhaust port and the vent, causing the gas to remain in the gap between the upper cover and the lower cover. At the same time, the driven member is located on the outermost periphery of the lower cover, so that when the upper cover drives the driven member to rotate, the torque transmission is greater and more even, so that the user can drive the lower cover to rotate with less force, improving the user experience.

[0019] In a preferred embodiment of a portable food processor, a sealing gasket is sandwiched between the upper and lower covers.

[0020] By clamping a sealing gasket between the upper and lower covers, the contact surfaces of the upper and lower covers are tightly fitted, effectively preventing food residue from seeping into the joint gaps, while ensuring that internal gas can be smoothly discharged, improving sealing performance and ease of cleaning, and further optimizing the user experience.

[0021] In a preferred embodiment of a portable food processor, the inner wall of the top of the cup body is provided with a second limiting protrusion that convexes radially inward, and the lower cover is provided with an extension that extends into the cup body, and the outer wall of the extension is provided with a swivel that engages with the second limiting protrusion.

[0022] By providing a radially inwardly protruding second limiting protrusion on the inner wall of the top of the cup body, and an extension extending into the cup body on the lower cover, with a swivel on the outer wall of the extension that engages with the second limiting protrusion, the second limiting protrusion can precisely align with the swivel when the user screws the cup lid onto the cup body, ensuring that the cup lid and cup body are tightly locked together and preventing loosening or falling off during use.

[0023] In a preferred embodiment of a portable food processor, the food processor further includes a main unit, which contains a motor, a grinding chamber containing a grinding device that is connected to the motor for transmission, and a cup body that is detachably connected to the main unit at the bottom.

[0024] In a preferred embodiment of a portable food processor, a motor is fixedly connected to the bottom of the cup body, a grinding device is provided inside the grinding chamber, and the motor shaft extends into the grinding chamber to be connected to the grinding device for transmission.

Detailed Implementation

[0038] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0039] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 10 As shown, this utility model provides a portable food processor, including a cup body 2 with a grinding chamber and a cup lid 1 detachably covering the cup body 2. The cup lid 1 includes an upper cover 11 and a lower cover 12 rotatably connected below the upper cover 11, with the upper cover 11 covering and shielding the lower cover 12. A motor 4 and a micro switch 5 electrically connected to the motor 4 are also provided below the cup body 2. A movable trigger rod 6 is provided inside the cup body 2. The upper cover 11 has a downwardly extending trigger part, and the lower cover 12 has an axially penetrating discharge... The upper cover 11 has an axially penetrating vent 112. The upper cover 11 can rotate relative to the lower cover 12 so that the vent 112 coincides with or is misaligned with the exhaust port 1211, so as to open or close the exhaust port 1211. The upper cover 11 and the lower cover 12 are provided with a mutually cooperating follower structure. After the upper cover 11 rotates to open the exhaust port 1211, it can continue to rotate and drive the lower cover 12 to rotate through the follower structure to fix the cup lid 1 to the cup body 2 and push the trigger linkage 6 to move downward to trigger the micro switch 5.

[0041] This application uses a cup lid 1 that includes an upper lid 11 and a lower lid 12 rotatably connected below the upper lid 11. The upper lid 11 has a downwardly extending trigger part, the lower lid 12 has an axially penetrating exhaust port 1211, and the upper lid 11 has an axially penetrating vent 112. The upper lid 11 can rotate relative to the lower lid 12 so that the vent 112 and the exhaust port 1211 coincide or are misaligned, so as to open or close the exhaust port 1211. That is, when the user needs to open the exhaust port 1211, he rotates the upper lid 11 so that the vent 112 and the exhaust port 1211 coincide, so that the grinding chamber is connected to the outside. When the user needs to close the exhaust port 1211, he rotates the upper lid 11 until the exhaust port 1211 and the vent 112 are misaligned, so that the grinding chamber is isolated from the outside. This design allows users to flexibly control the opening and closing of the vent 1211 by rotating the top cover 11 to meet venting needs in different working states. For example, when processing food ingredients in a food processor, the user can rotate the top cover 11 to open the vent 1211 to release gases generated during the grinding and heating processes, preventing excessive pressure in the grinding chamber from causing the lid 1 to lift. Simultaneously, when carrying or storing food, the user can rotate the top cover 11 to close the vent 1211 to prevent food spillage, ensuring ease of use and safety, and improving the user experience. Compared to existing methods that use a movable plate to open and close the vent 1211, rotating the top cover 11 allows the vent 112 to overlap or misalign with the vent 1211 to open or close the vent 1211. Even after prolonged use, the top cover 11 maintains a stable connection with the bottom cover 12. Misalignment of the vent 112 with the vent 1211 seals the vent 1211, ensuring a consistent seal on the cup body 2.

[0042] Meanwhile, the upper cover 11 covers and shields the lower cover 12, enhancing the sealing between the upper cover 11 and the lower cover 12. This prevents leakage at the connection between the upper cover 11 and the lower cover 12, thus preventing food residue from entering the connection gap and causing the upper cover 11 to get stuck or difficult to clean when rotating relative to the lower cover 12, ensuring stability and hygiene for long-term use.

[0043] Furthermore, the upper cover 11 and the lower cover 12 are equipped with a mutually cooperating follower structure. After the upper cover 11 rotates to open the vent 1211, it can continue to rotate, and through the follower structure, it drives the lower cover 12 to rotate, thereby fixing the cup lid 1 to the cup body 2 and pushing the trigger linkage 6 downward to trigger the micro switch 5. This allows the user to place the cup lid 1 on the cup body 2, hold the upper cover 11 and rotate it. Under the force, the upper cover 11 rotates towards the direction of opening the vent 1211. When the upper cover 11 rotates to the position where the vent 112 and the vent 1211 coincide, the vent 1211 is opened. At the same time, the upper cover 11 continues to rotate and, with the help of the follower structure, drives the lower cover 12 to rotate together until... The lid 1 is securely locked to the cup body 2. After the lid 1 is fixed to the cup body 2, it can simultaneously push the trigger lever 6 downwards to trigger the micro switch 5. This ensures that the lid 1 can only push the trigger lever 6 to trigger the micro switch 5 when the exhaust port 1211 is open and the lid 1 is securely fastened to the cup body 2, thus starting the motor 4 to process the food. This ensures that gas can be smoothly discharged through the exhaust port 1211 during food processing, guaranteeing the stability of food processing and preventing excessive pressure inside the grinding chamber caused by processing food with the exhaust port 1211 closed. It also prevents accidental starting of the motor 4, improving operational safety. Furthermore, it achieves simultaneous operation of opening the exhaust port 1211, fixing the lid 1, and triggering the micro switch 5, simplifying the user's operation steps and improving ease of use and efficiency.

[0044] As a preferred embodiment of this application, such as Figure 3 , Figure 4 , Figure 5 As shown, the follower structure includes an active part provided on the upper cover 11 and a driven part provided on the lower cover 12. The active part can rotate circumferentially relative to the driven part to open or close the exhaust port 1211 of the upper cover 11. After the active part rotates to abut against the driven part, it can drive the lower cover 12 to rotate so that the cup lid 1 is fixed or detached from the cup body 2.

[0045] By configuring the follower structure to include an active part on the upper cover 11 and a driven part on the lower cover 12, the active part can rotate circumferentially relative to the driven part to open or close the vent 1211 of the upper cover 11. After the active part rotates to abut against the driven part, it can drive the lower cover 12 to rotate so that the cup lid 1 is fixed or detached from the cup body 2. That is, when the user rotates the upper cover 11, the active part rotates accordingly, and at this time the active part and the driven part do not abut circumferentially, so that the upper cover 11 can rotate relative to the lower cover 12, thereby making the vent 112 coincide with or offset from the vent 1211. When the active part rotates to abut against the driven part, the active part drives the driven part to rotate together, thereby realizing the function of the upper cover 11 driving the lower cover 12 to rotate together, ensuring the smooth opening or closing of the vent 1211, and at the same time, it can also realize the fixation or detachment of the upper cover 11 driving the lower cover 12 from the cup body 2.

[0046] It should be noted that this application does not specifically limit the structure of the driving and driven parts. As one preferred embodiment of this application, such as... Figure 3 , Figure 4 , Figure 5 As shown, the active part is a drive column 111 extending downward from the upper cover 11, and the driven part is a driven groove 1231 extending circumferentially from the lower cover 12. The drive column 111 extends into the driven groove 1231 and abuts against both ends of the driven groove 1231 during rotation to drive the lower cover 12 to rotate.

[0047] By using a drive column 111 extending downward from the upper cover 11 as the active part and a driven groove 1231 extending circumferentially from the lower cover 12 as the driven part, the drive column 111 extends into the driven groove 1231, allowing it to slide within the driven groove 1231 as the upper cover 11 rotates. This enables relative rotation of the upper cover 11 relative to the lower cover 12, thereby opening or closing the exhaust port 1211. When the upper cover 11 rotates to open or close the exhaust port 1211, the drive column 111 simultaneously abuts against both ends of the driven groove 1231. As the upper cover 11 continues to rotate, the drive column 111 drives the driven groove 1231, i.e., the lower cover 12, to rotate together, ensuring the tight fixation or smooth disengagement of the cup lid 1 from the cup body 2. This further enhances the safety and convenience of operation. Furthermore, the simple structure of the active and driven parts facilitates production and helps reduce production costs.

[0048] Furthermore, such as Figure 3 , Figure 4 , Figure 5 , Figure 10 As shown, the top opening of the driven groove 1231 is provided with a limiting ring rib 1232 that extends circumferentially along the driven groove 1231 and protrudes inward. The bottom of the drive column 111 is provided with a first limiting protrusion 1111 with an enlarged outer diameter. The top wall of the first limiting protrusion 1111 abuts against the bottom wall of the limiting ring rib 1232.

[0049] By providing a limiting ring rib 1232 extending circumferentially and protruding inwardly at the top opening of the driven groove 1231, and a first limiting protrusion 1111 with an enlarged outer diameter at the bottom of the drive column 111, the top wall of the first limiting protrusion 1111 abuts against the bottom wall of the limiting ring rib 1232, so that after the drive column 111 extends into the driven groove 1231, the limiting ring rib 1232 can vertically limit the first limiting protrusion 1111, ensuring that the drive column 111 is positioned within the driven groove 1231. Within the moving groove 1231, the axial connection between the upper cover 11 and the lower cover 12 is achieved, preventing the cup lid 1 from failing to screw into place due to unstable connection between the upper cover 11 and the lower cover 12, which could lead to separation or misalignment. Furthermore, the drive column 111 and the driven groove 1231 achieve axial connection between the upper cover 11 and the lower cover 12 while simultaneously driving rotation, eliminating the need for additional structural components to connect the upper cover 11 and the lower cover 12, further simplifying the overall structure and improving product reliability.

[0050] Specifically, such as Figure 5 , Figure 10 As shown, a notch is provided on the limiting ring rib 1232. When assembling the upper cover 11 and the lower cover 12, the first limiting protrusion 1111 is inserted into the driven groove 1231 through the notch. By rotating, the first limiting protrusion 1111 and the notch are vertically misaligned, thereby realizing the assembly of the upper cover 11 and the lower cover 12. This eliminates the need for additional structural components such as screws to connect the two, which helps to simplify the structure of the cup lid 1 and improve assembly efficiency. In addition, if there are foreign objects between the upper cover and the lower cover, the user can separate the upper cover 11 and the lower cover 12 by vertically aligning the first limiting protrusion 1111 with the notch and lifting it upwards, making the separation more convenient and quick.

[0051] It should also be noted that this application does not specifically limit the molding method of the driven part. It can be that the exhaust port 1211 and the driven part are both molded on the same structural component, or it can be a preferred embodiment of this application, such as... Figure 3 , Figure 4 , Figure 5 As shown, the lower cover 12 includes a lower cover 12 body with an exhaust port 1211 and a follower 123 fixedly connected to the upper part of the lower cover 12 body. The follower is formed on the follower 123, and the exhaust port 1211 is formed on the lower cover 12 body.

[0052] By configuring the lower cover 12 as including a lower cover 12 body with an exhaust port 1211 and a follower 123 fixedly connected above the lower cover 12 body, and forming the follower part on the follower part 123, the lower cover 12 is more convenient and quick to form. This avoids the situation where the exhaust port 1211 and the follower part are formed simultaneously on the same structural component, which would make the structure complex and difficult to form. This helps to improve product yield and production efficiency.

[0053] Furthermore, such as Figure 3 , Figure 4 , Figure 5 As shown, the lower cover 12 body includes a fixing part 122 and an exhaust part 121 that protrudes upward from the middle of the fixing part 122. The driven member 123 is annular and sleeved on the outer periphery of the exhaust part 121 and fixedly connected to the fixing part 122. The exhaust port 1211 is provided on the top wall of the exhaust part 121.

[0054] By including a fixing part 122 and an exhaust part 121 that protrudes upward from the middle of the fixing part 122, the driven member 123 is annular and sleeved on the outer periphery of the exhaust part 121 and fixedly connected to the fixing part 122. The exhaust port 1211 is located on the top wall of the exhaust part 121, so that the exhaust port 1211 is relatively closer to the upper cover 11. This allows the gas discharged from the exhaust port 1211 to be directly discharged outward through the vent 112, avoiding the situation where the gas is stored in the gap between the upper cover 11 and the lower cover 12 due to the large distance between the exhaust port 1211 and the vent 112. At the same time, the driven member 123 is located on the outermost periphery of the lower cover 12, so that when the upper cover 11 drives the driven member 123 to rotate, the torque transmission is greater and more uniform, so that the user can drive the lower cover 12 to rotate with less force, thus improving the user experience.

[0055] As a preferred embodiment of this application, such as Figure 3 , Figure 4 , Figure 5 As shown, a sealing gasket 7 is sandwiched between the upper cover 11 and the lower cover 12.

[0056] By clamping a sealing gasket 7 between the upper cover 11 and the lower cover 12, the contact surfaces of the upper cover 11 and the lower cover 12 are tightly fitted, effectively preventing food residue from seeping into the connection gap, while ensuring that internal gas can be smoothly discharged, improving sealing performance and ease of cleaning, and further optimizing the user experience.

[0057] It should be noted that this application does not specifically limit the connection and fixing method between the cup lid 1 and the cup body 2. It can be that the lower lid 12 has external threads and the inner wall of the cup body 2 has internal threads, with the two connected and fixed by the threads; or it can be, as... Figure 5 As shown, as a preferred embodiment of this application, the inner wall of the top of the cup body 2 is provided with a second limiting protrusion that bulges inward radially, and the lower cover 12 is provided with an extension 124 that extends into the cup body 2, and the outer wall of the extension 124 is provided with a swivel 1241 that engages with the second limiting protrusion for limiting.

[0058] By providing a radially inwardly protruding second limiting protrusion on the inner wall of the top of the cup body 2, and providing an extension 124 extending into the cup body 2 on the lower cover 12, and providing a swivel 1241 on the outer wall of the extension 124 that engages with the second limiting protrusion, the second limiting protrusion can precisely engage with the swivel 1241 when the user screws the cup lid 1 onto the cup body 2, ensuring that the cup lid 1 and the cup body 2 are tightly locked, preventing loosening or falling off during use.

[0059] It should be noted that this application does not specifically limit the structure of the food processing machine, which can be any of the following embodiments:

[0060] Example 1: As Figure 1 , Figure 2 As shown, in this embodiment, the food processing machine also includes a main unit 3, a motor 4 is provided inside the main unit 3, a crushing device is provided inside the crushing chamber and is connected to the motor 4 for transmission, and the bottom end of the cup body 2 is detachably connected to the main unit 3.

[0061] Example 2: In this example, a motor 4 is also fixedly connected to the bottom of the cup body 2, and a crushing device is provided in the crushing chamber. The rotating shaft of the motor 4 extends into the crushing chamber to be connected to the crushing device for transmission.
