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, the sealing effect of the spout can be significantly reduced due to component aging and other issues, causing liquid to easily leak out when the cup is being carried. Furthermore, the movable plate, pivotally connected to the lid, cannot be designed as a large structure, resulting in a smaller sealing area for the spout and consequently a smaller spout diameter. This leads to lower venting efficiency during food processing, preventing timely pressure release within the cup and ultimately causing the lid to lift, interrupting food processing and severely impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a portable food processor to solve the problems of existing portable food processors that, while providing a spout and a movable plate that can close the spout for user convenience, fail to prevent the spout from becoming unsealed due to unstable fit between the movable plate and the cup lid after long-term use, and also prevent the spout from being too small due to the size of the movable plate, resulting in untimely venting.

[0004] To achieve the above objectives, this utility model provides a portable food processor, including a cup body with a grinding chamber and a cup lid detachably covering the cup body. A motor and a micro switch electrically connected to the motor are located below the cup body. A movable trigger linkage is provided inside the cup body. The cup lid includes a cup lid body and a rotating cover rotatably connected above the cup lid body. The cup lid body has a first exhaust port that extends through the axial direction, and the rotating cover has a second exhaust port that extends through the axial direction. The rotating cover can rotate relative to the cup lid body to make the second exhaust port coincide with or misalign with the first exhaust port, so as to open or close the first exhaust port. When the rotating cover opens the first exhaust port, it can push the trigger linkage downward to trigger the micro switch.

[0005] This application describes a cup lid comprising a lid body and a rotating cover rotatably connected above the lid body. The lid body has a first axially penetrating vent, and the rotating cover has a second axially penetrating vent. The rotating cover can rotate relative to the lid body to align or misalign the second vent with the first vent, thereby opening or closing the first vent. Specifically, when the user needs to open the first vent, they rotate the rotating cover to align the second vent with the first vent, thus connecting the grinding chamber to the outside. When the user needs to close the first vent, they rotate the rotating cover to misalign the first and second vents, thus isolating the grinding chamber from the outside. This allows the user to flexibly control the opening and closing of the first vent by rotating the rotating cover to meet venting needs in different working states. For example, when processing food ingredients in a food processor, the user can rotate the rotating cover to open the first 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 rotating cover to close the first vent to prevent food spillage, ensuring convenience and safety, and improving the user experience. Simultaneously, the rotating lid, rotatably connected to the top of the cup lid, allows for a larger size, enabling a larger diameter for the second exhaust port, and consequently, a larger diameter for the first exhaust port. This increases the flow rate of gas expelled from the cup per unit time, ensuring pressure balance inside and outside the cup and facilitating smooth food processing. Furthermore, compared to existing methods that use a movable plate to open and close the first exhaust port, the rotating lid allows the second exhaust port to align with or offset from the first, opening or closing the exhaust. Even after prolonged use, the rotating lid maintains a secure connection with the lower lid. As long as the second exhaust port is misaligned with the first, it effectively seals the first exhaust port, maintaining a consistent seal within the cup.

[0006] Preferably, the direction in which the lid is rotated to open the first vent is the same as the direction in which the lid is screwed onto the cup body, so that the first vent can be opened at the same time as the lid is screwed on, thus ensuring the smooth processing of subsequent ingredients.

[0007] Simultaneously, when the rotating cover opens the first exhaust port, it can push the trigger linkage downward to trigger the micro switch. This ensures that the user can only push the trigger linkage to trigger the micro switch when the first exhaust port is open, thus starting the motor to process the food. This ensures that gas can be smoothly discharged through the first exhaust port during food processing, guaranteeing the stability of food processing and preventing excessive pressure in the grinding chamber caused by processing food with the first exhaust port closed. It also prevents accidental motor start-up, improving operational safety.

[0008] In a preferred embodiment of a portable food processor, the rotation axis of the rotating cover is collinear with the central axis of the cup lid body, and the rotation path of the second exhaust port overlaps with that of the first exhaust port.

[0009] By aligning the rotation axis of the rotating cover with the central axis of the cup lid body, and ensuring the rotation path of the second exhaust port overlaps with the first exhaust port, the rotating cover can drive the second exhaust port to rotate until it coincides with the first exhaust port. This allows the first exhaust port to smoothly connect with the outside, enabling the gas inside the grinding chamber to be discharged outwards and maintaining pressure balance inside and outside the grinding chamber. Compared to the traditional method of using a rotating plate to open or close the exhaust port, this design allows for a sufficiently large cup lid body to accommodate the rotating cover, improving the connection stability between the rotating cover and the cup lid body. The rotating cover can also be larger, allowing for a larger second exhaust port for smoother and faster exhaust. Furthermore, it increases the contact area between the rotating cover and the cup lid body, ensuring the reliability of the rotating cover in its current position when rotating to open or close the first exhaust port. This prevents the trigger linkage from failing to activate the microswitch during food processing, and also prevents the slurry from flowing out of the cup body when the rotating cover closes the first exhaust port.

[0010] In a preferred embodiment of a portable food processor, the rotating lid includes a circular plate with a second vent and a limiting plate extending outward from the circular plate, and the lid body has an anti-rotation part that prevents the limiting plate from rotating circumferentially.

[0011] By configuring the rotating lid as a circular plate including a second exhaust port and a limiting plate extending outward from the circular plate, and by providing an anti-rotation part that prevents the limiting plate from rotating circumferentially, the rotating lid can connect to the lid body via the circular plate. During rotation, the second exhaust port rotates to overlap or misalign with the first exhaust port, ensuring precise control of the first exhaust port. Furthermore, the anti-rotation part on the lid body restricts the lid's free rotation. When the first and second exhaust ports are fully overlapped, the anti-rotation part limits the limiting plate, preventing excessive rotation that could lead to inaccurate alignment between the second and first exhaust ports. This not only ensures more precise alignment of the first and second exhaust ports and smooth exhaust flow from the first port, but also facilitates user operation, eliminating the need for manual alignment and improving the user experience.

[0012] In a preferred embodiment of a portable food processor, the anti-rotation part is an anti-rotation groove formed by a recess in the top surface of the cup lid body, and the limiting plate is configured to conform to the anti-rotation groove and can abut against the two circumferential ends of the anti-rotation groove.

[0013] By setting the anti-rotation part as an anti-rotation groove formed by the recess of the top surface of the cup lid body, and the limiting plate being set in the same shape as the anti-rotation groove and abutting against the two circumferential ends of the anti-rotation groove, the limiting plate can reciprocate within the anti-rotation groove. When it rotates to a specific position, the two circumferential ends of the anti-rotation groove can effectively limit the further rotation of the limiting plate, ensuring that the second exhaust port is precisely aligned with the first exhaust port, thereby ensuring the stability of the exhaust system and the convenience of operation. At the same time, the setting of the limiting plate and the anti-rotation groove can ensure the overall consistency of the cup lid and reduce the space occupied by the cup lid, making it convenient for users to carry and use.

[0014] In a preferred embodiment of a portable food processor, the top surface of the cup lid body is provided with a recessed groove to accommodate a circular plate, and the anti-rotation part is a radially convex annular groove provided on the peripheral wall of the groove, and the limiting plate can abut against the two circumferential ends of the annular groove.

[0015] By incorporating a recessed groove on the top surface of the lid to accommodate a circular plate, the plate can be embedded within the groove. This not only enhances connection stability but also prevents the circular plate from protruding outwards, thus avoiding discomfort for the user when handling the lid and improving the user experience. Furthermore, the anti-rotation part is a radially protruding annular groove on the circumferential wall of the groove. A limiting plate abuts against both ends of the annular groove, allowing the circular plate to rotate and engage with the ends of the annular groove, thereby preventing circumferential rotation of the circular plate. This ensures that the circular plate does not rotate excessively during operation, further improving the alignment accuracy of the vent and guaranteeing the operational stability of the food processor and the user experience.

[0016] In a preferred embodiment of a portable food processor, a sealing gasket is sandwiched between the rotating lid and the cup lid body, and the sealing gasket has a clearance opening that is axially aligned with the first exhaust port.

[0017] By sandwiching a sealing gasket between the rotating lid and the lid body, the fit between the two is made tighter. This effectively prevents water from entering the gap between the lid and the rotating lid when the lid is cleaned, ensuring the internal structure remains dry and clean. Simultaneously, the sealing gasket has a clearance opening that axially aligns with the first vent. This ensures precise alignment with the vent during venting, guaranteeing smooth venting and preventing internal pressure buildup due to obstructed venting, further enhancing safety and user experience.

[0018] In a preferred embodiment of a portable food processor, the sealing gasket is provided with a first sealing ring rib extending upward from a self-avoiding opening.

[0019] By providing a first sealing ring rib extending upward from the sealing gasket, when the second vent is aligned with the first vent, the first sealing ring rib can effectively seal between the first vent and the second vent, preventing food residue or liquid from entering the cup lid through the gap between the first vent and the second vent, thus further ensuring the cleanliness and hygiene of the inside of the cup lid.

[0020] In a preferred embodiment of a portable food processor, the sealing gasket is provided with an upwardly extending second sealing ring rib, and when the cover is rotated to close the first exhaust port position, the top of the second sealing ring rib abuts against the outer periphery of the second exhaust port.

[0021] When the rotating cover is opened to the first vent position, the top of the second sealing ring rib abuts against the outer periphery of the second vent. This allows the second sealing ring rib to effectively seal the second vent when the rotating cover is turned to close the first vent. This prevents cleaning water from entering the inside of the cup lid through the second vent during cleaning, ensuring the inside of the cup lid remains dry and improving the cleaning effect and user experience.

[0022] In a preferred embodiment of a portable food processor, the rotating cover is further provided with an operating part for turning, the operating part being located on a side away from the rotation axis of the rotating cover.

[0023] The rotating cover also has a toggle mechanism, which allows users to easily control the rotation of the cover by toggling the mechanism, making operation more convenient. At the same time, the mechanism is located on the side away from the rotation axis of the cover, making it easier for users to toggle the cover and improving the user experience.

[0024] In a preferred embodiment of a portable food processor, the food processor further includes a main unit, which houses a motor, and a grinding chamber containing a grinding device connected to the motor via a drive connection. The bottom of the cup is detachably connected to the main unit; or...

[0025] A motor is also fixedly connected to the bottom of the cup body, and a crushing device is installed inside the crushing chamber. The motor shaft extends into the crushing chamber to be connected to the crushing device for transmission. Attached Figure Description

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 9 As shown, this utility model provides a portable food processor, including a cup body 3 with a grinding chamber 31 and a cup lid detachably covering the cup body 3. A motor 6 and a micro switch 7 electrically connected to the motor 6 are provided below the cup body 3. A movable triggering rod 8 is provided inside the cup body 3. The cup lid includes a cup lid body 1 and a rotating cover 2 rotatably connected above the cup lid body 1. The cup lid body 1 has a first exhaust port 12 that passes through axially, and the rotating cover 2 has a second exhaust port 23 that passes through axially. The rotating cover 2 can rotate relative to the cup lid body 1 so that the second exhaust port 23 coincides with or is misaligned with the first exhaust port 12, so as to open or close the first exhaust port 12. When the rotating cover 2 opens the first exhaust port 12, it can push the triggering rod 8 to move downward to trigger the micro switch 7.

[0041] This application configures the cup lid as including a cup lid body 1 and a rotating cover 2 rotatably connected above the cup lid body 1. The cup lid body 1 has a first exhaust port 12 that extends through the axial direction, and the rotating cover 2 has a second exhaust port 23 that extends through the axial direction. The rotating cover 2 can rotate relative to the cup lid body 1 so that the second exhaust port 23 coincides with or is misaligned with the first exhaust port 12, so as to open or close the first exhaust port 12. That is, when the user needs to open the first exhaust port 12, he rotates the rotating cover 2 so that the second exhaust port 23 coincides with the first exhaust port 12, thereby connecting the grinding chamber 31 with the outside. When the user needs to close the first exhaust port 12, he rotates the rotating cover 2 until the first exhaust port 12 is misaligned with the second exhaust port 23, so as to isolate the grinding chamber 31 from the outside. This allows users to flexibly control the opening and closing of the first exhaust port 12 by rotating the rotating cover 2 to meet the exhaust needs of different working states. For example, when users need to process ingredients using the food processor, they can rotate the rotating cover 2 to open the first exhaust port 12 to release the gas generated during the crushing and heating processes, thus preventing the lid from being lifted due to excessive pressure in the crushing chamber 31. At the same time, when users are carrying or storing food, they can rotate the rotating cover 2 to close the first exhaust port 12 to prevent food from overflowing, ensuring ease of use and safety, and improving the user experience.

[0042] Meanwhile, the rotating cover 2 is rotatably connected to the upper part of the cup lid body 1, allowing the size of the rotating cover 2 to be set larger, thus allowing the diameter of the second exhaust port 23 to be set larger, and consequently the diameter of the first exhaust port 12 to be set larger. This increases the flow rate of gas discharged from the cup body 3 per unit time, ensuring pressure balance inside and outside the cup body 3 and ensuring smooth food processing. Furthermore, compared to the existing method of opening and closing the first exhaust port 12 through a movable plate, the rotating cover 2 rotates to make the second exhaust port 23 coincide with or misalign with the first exhaust port 12 to open or close the exhaust port. Even after prolonged use, the rotating cover 2 can always maintain a stable connection with the lower cover. As long as the second exhaust port 23 is misaligned with the first exhaust port 12, it can seal the first exhaust port 12, maintaining a consistent sealing effect on the cup body 3.

[0043] Preferably, the direction in which the rotating lid 2 is rotated to open the first vent 12 is consistent with the direction in which the cup lid is screwed onto the cup body 3, so that the first vent 12 can be opened at the same time as the cup lid is screwed on, thereby ensuring the smooth progress of subsequent food processing.

[0044] Simultaneously, when the cover 2 is rotated to open the first exhaust port 12, the triggering rod 8 can be pushed downward to trigger the micro switch 7. More preferably, the triggering rod 8 can only trigger the micro switch 7 when the first exhaust port 12 and the second exhaust port 23 are completely aligned vertically. This ensures that the user can only push the triggering rod 8 to trigger the micro switch 7 when the first exhaust port 12 is opened, and only then can the motor 6 be started to process the food. This ensures that the gas can be smoothly discharged through the first exhaust port 12 during food processing, guaranteeing the stability of food processing and preventing excessive pressure in the grinding chamber 31 caused by food processing when the first exhaust port 12 is not open. It also prevents the motor 6 from starting due to misoperation, thus improving operational safety.

[0045] As a preferred embodiment of this application, such as Figure 2 , Figure 5 As shown, the rotation axis of the rotating cover 2 is collinear with the central axis of the cup cover body 1, and the rotation path of the second exhaust port 23 overlaps with the first exhaust port 12.

[0046] By aligning the rotation axis of the rotating cover 2 with the central axis of the cup lid body 1, and ensuring that the rotation path of the second exhaust port 23 overlaps with the first exhaust port 12, the rotating cover 2 can rotate the second exhaust port 23 to coincide with the first exhaust port 12. This allows the first exhaust port 12 to connect smoothly with the outside, thereby enabling the gas inside the pulverizing chamber 31 to be discharged outwards and ensuring pressure balance inside and outside the pulverizing chamber 31. Compared to the traditional method of using a rotating plate to open or close the exhaust port, this design allows the cup lid body 1 to have a sufficiently large size to accommodate the rotating cover 2, improving the connection stability between the rotating cover 2 and the cup lid body 1. Furthermore, the rotating cover 2 can be made larger, allowing for a larger second exhaust port, resulting in smoother and faster venting of the cup. Furthermore, it allows for a larger contact area between the rotating cover 2 and the cup lid body 1, ensuring the reliability of the rotating cover 2 in its current position when rotating to open or close the first exhaust port 12. This prevents the rotating cover 2 from causing the trigger linkage 8 to fail to trigger the micro switch 7 when the food processing machine is in operation. It also prevents the slurry from flowing out of the cup body 3 when the rotating cover 2 is closed at the first exhaust port 12.

[0047] Furthermore, such as Figure 1 , Figure 3 As shown, the rotating cover 2 includes a circular plate 21 with a second exhaust port 23 and a limiting plate 22 extending outward from the circular plate 21. The cup cover body 1 is provided with a non-rotation part that prevents the limiting plate 22 from rotating circumferentially.

[0048] By configuring the rotating cover 2 as a circular plate 21 including a second exhaust port 23 and a limiting plate 22 extending outward from the circular plate 21, and the cup lid body 1 having an anti-rotation part that prevents the limiting plate 22 from rotating circumferentially, the rotating cover 2 can be connected to the cup lid body 1 through the circular plate 21. During rotation, the second exhaust port 23 rotates to overlap or misalign with the first exhaust port 12, ensuring precise control of the first exhaust port 12. Furthermore, by providing an anti-rotation part on the cup lid body 1, the arbitrary rotation of the rotating cover 2 is restricted. When the rotating cover 2 rotates to the point where the first exhaust port 12 and the second exhaust port 23 are completely overlapped, the anti-rotation part can limit the rotation of the limiting plate 22, preventing the rotating cover 2 from rotating excessively and causing the second exhaust port 23 to misalign with the first exhaust port 12. This not only makes the alignment of the first exhaust port 12 and the second exhaust port 23 more precise, ensuring smooth exhaust from the first exhaust port 12, but also facilitates user operation, eliminating the need for manual alignment and improving the user experience.

[0049] It should be noted that this application does not specifically limit the structure of the lower limit plate 22 and the anti-rotation part in this embodiment, and they can be any one of the following embodiments:

[0050] Example 1: As Figure 3 As shown, in this embodiment, the anti-rotation part is an anti-rotation groove 11 formed by the recess of the top surface of the cup lid body 1. The limiting plate 22 is configured to conform to the anti-rotation groove 11 and can abut against the two circumferential ends of the anti-rotation groove 11.

[0051] By setting the anti-rotation part as an anti-rotation groove 11 formed by the recess of the top surface of the cup lid body 1, and the limiting plate 22 is set in the same shape as the anti-rotation groove 11 and can abut against the two circumferential ends of the anti-rotation groove 11, the limiting plate 22 can reciprocate within the anti-rotation groove 11. When it rotates to a specific position, the two circumferential ends of the anti-rotation groove 11 can effectively limit the further rotation of the limiting plate 22, ensuring that the second exhaust port 23 and the first exhaust port 12 are accurately aligned, thereby ensuring the stability of the exhaust system and the convenience of operation. At the same time, the setting of the limiting plate 22 and the anti-rotation groove 11 in the same shape can ensure the overall consistency of the cup lid and reduce the space occupied by the cup lid, making it convenient for users to carry and use.

[0052] Furthermore, such as Figure 3 , Figure 4 As shown, when the rotating cover 2 is rotated to open the first exhaust port 12, and the end of the limiting plate 22 abuts against the anti-rotation groove 11, the bottom end of the limiting plate 22 pushes the trigger link 8 downward and triggers the micro switch 7. At the same time, when the user rotates the rotating cover 2 to close the first exhaust port 12, the bottom end of the limiting plate 22 loses its drive on the top of the trigger link 8, moves upward and resets under the drive of the spring, and thus loses the trigger on the micro switch 7.

[0053] Example 2: In this example, the top surface of the cup lid body 1 is provided with a recessed groove to accommodate the circular plate 21, and the anti-rotation part is a radially convex annular groove provided on the peripheral wall of the groove, and the limiting plate 22 can abut against the two circumferential ends of the annular groove.

[0054] By providing a recessed groove on the top surface of the cup lid body 1 to accommodate the circular plate 21, the circular plate 21 can be embedded in the groove. This not only enhances connection stability but also prevents the circular plate 21 from protruding outwards, which could cause discomfort when the user picks up the cup lid, thus improving the user experience. Furthermore, the anti-rotation part is a radially protruding annular groove on the peripheral wall of the groove. The limiting plate 22 can abut against both ends of the annular groove, so that when the circular plate 21 rotates, it drives the limiting plate 22 to rotate and abut against both ends of the annular groove, thereby preventing the circular plate 21 from rotating excessively. This further improves the alignment accuracy of the vent, ensuring the operational stability of the food processor and the user experience.

[0055] Of course, the structure of the cup lid in this application is not limited to the above-described configuration, such as... Figure 9 As shown, it can also be that the rotating cover 2 covers and shields the cup lid body 1, so as to completely shield the cup lid body 1 and make the overall integrity of the cup lid more consistent.

[0056] As a preferred embodiment of this application, such as Figure 5 As shown, a sealing gasket 5 is also sandwiched between the rotating cover 2 and the cup lid body 1, and the sealing gasket 5 is provided with a clearance opening that is axially aligned with the first exhaust port 12.

[0057] By sandwiching a sealing gasket 5 between the rotating cover 2 and the cup lid body 1, the fit between the rotating cover 2 and the cup lid body 1 is made tighter. This effectively prevents water from entering the gap between the cup lid body 1 and the rotating cover 2 when the cup lid is cleaned, ensuring the dryness and cleanliness of the internal structure. At the same time, the sealing gasket 5 has a clearance opening that axially aligns with the first exhaust port 12. This ensures that the clearance opening can be precisely aligned with the first exhaust port 12 during the exhaust process, ensuring smooth exhaust and preventing internal pressure buildup due to poor exhaust, further improving safety and user experience.

[0058] Furthermore, such as Figure 8 As shown, the sealing gasket 5 is provided with a first sealing ring rib 51 extending upward from the clearance opening.

[0059] By providing a first sealing ring rib 51 extending upward from the self-avoiding opening in the sealing gasket 5, when the second vent 23 is aligned with the first vent 12, the first sealing ring rib 51 can effectively seal between the first vent 12 and the second vent 23, preventing food residue or liquid from entering the cup lid through the gap between the first vent 12 and the second vent 23, and further ensuring the cleanliness and hygiene of the inside of the cup lid.

[0060] As a preferred embodiment of this implementation, such as Figure 8 As shown, the sealing gasket 5 is provided with an upwardly extending second sealing ring rib 52. When the rotating cover 2 closes the first exhaust port 12, the top of the second sealing ring rib 52 abuts against the outer periphery of the second exhaust port 23.

[0061] When the rotating cover 2 is opened to the first vent 12 position, the top of the second sealing ring rib 52 abuts against the outer periphery of the second vent 23, so that when the rotating cover 2 is rotated to close the first vent 12, the second sealing ring rib 52 can effectively seal the second vent 23, thereby preventing cleaning water from entering the inside of the cup lid through the second vent 23 when cleaning the cup lid, ensuring that the inside of the cup lid is dry, improving the cleaning effect and user experience.

[0062] As a preferred embodiment of this application, such as Figure 7 As shown, the rotating cover 2 is also provided with an operating part 24 for turning, and the operating part 24 is located on the side away from the rotation axis of the rotating cover 2.

[0063] By providing an operating part 24 for tossing the rotating cover 2, the user can easily control the rotation of the rotating cover 2 by tossing the operating part 24, making the operation more convenient. At the same time, the operating part 24 is located on the side away from the rotation axis of the rotating cover 2, which makes it easier for the user to toss the rotating cover 2, thus improving the user experience.

[0064] 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:

[0065] Example 1: As Figure 4 As shown, in this embodiment, the food processing machine also includes a main unit 4, a motor 6 is provided inside the main unit 4, a crushing device is provided inside the crushing chamber 31 and is connected to the motor 6 in a transmission, and the bottom end of the cup body 3 is detachably connected to the main unit 4.

[0066] Example 2: In this example, a motor 6 is fixedly connected to the bottom of the cup body 3, and a crushing device is provided in the crushing chamber 31. The rotating shaft of the motor 6 extends into the crushing chamber 31 to be connected to the crushing device for transmission.

[0067] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
