Description

Technical Field

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

[0002] Existing food processing machines, such as shredders and slicers, typically include a main unit with a built-in motor, a material cylinder with a cutting chamber, a blade holder for loading and unloading within the cutting chamber, and an end cap that secures the blade holder within the cutting chamber. A feeding channel communicating with the cutting chamber is located above it. When using the food processing machine to cut food, the user adds food into the cutting chamber through the feeding channel. After entering the cutting chamber, the food is processed by the cutting blades and then discharged through a through-hole at the end cap, completing the food processing. To facilitate cleaning of the blade holder and the ability to replace it with different blade holders for different cutting structures, some manufacturers design the blade holder to be detachably connected to the cutting chamber. This allows users to remove the blade holder from the cutting chamber for cleaning and to replace blade holders with different structures. However, in actual use, it was found that in addition to a lot of food residue remaining inside the blade barrel, a lot of food residue also remained in the feed tube. To facilitate cleaning of the feed tube, a food cutting device was disclosed in Chinese utility model patent CN202322587055.4, which also made the feed tube detachable from the main unit. When the user needs to clean the feed tube and blade barrel, the feed tube is first detached from the main unit, and then the blade barrel is detached from the transmission component connecting the motor and the blade barrel, thereby achieving all-round cleaning of the feed tube and blade barrel. However, users found that when the feed tube and blade barrel are detached, the end cap loses its axial positioning of the blade barrel, and the blade barrel and the transmission component are only limited in the circumferential direction. Therefore, the blade barrel is very easy to detach from the transmission component, causing the blade barrel to fall onto the table, which in turn causes the cutting edge on the blade barrel to wear or even be damaged, seriously affecting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a food processing machine with a stable structure to solve the problem in existing food processing machines where the connection between the blade barrel and the transmission component is unstable after the material barrel is detached from the main unit, causing the blade barrel to easily detach from the transmission component and fall onto the table and be damaged.

[0004] To achieve the above objectives, this utility model provides a structurally stable food processing machine, including a main unit with a built-in motor, a material cylinder detachably connected to the main unit and having a cutting chamber, a blade cylinder that can be removed from and placed in the cutting chamber and is driven by the motor, and an end cover that fixes the blade cylinder in the cutting chamber. The rear end of the material cylinder is connected to the main unit, and the front end is connected to the end cover. The food processing machine also includes a transmission component that drives between the blade cylinder and the motor. The blade cylinder has a transmission part on the side facing the transmission component, and the transmission component has an elastic buckle that engages with the transmission part.

[0005] This application designs the material cylinder to be detachably connected to the main unit, and the blade cylinder to be detachably connected to the cutting chamber. This allows users to first detach the material cylinder from the main unit after using the food processor. During this process, the blade cylinder simultaneously separates from the cutting chamber, enabling cleaning of the material cylinder. Then, the blade cylinder can be detached from the motor for deep cleaning, ensuring the cleanliness of both the material cylinder and the blade cylinder and preventing the accumulation of dirt or even mold due to prolonged lack of deep cleaning. Simultaneously, a transmission component is installed between the blade cylinder and the motor, allowing the torque output from the motor to be transmitted to the blade cylinder, thus enabling its rotation. Furthermore, a transmission unit is located on the side of the cutter barrel facing the transmission component. The transmission component has an elastic buckle that engages with the transmission unit. When the cutter barrel is connected to the transmission component, the elastic buckle engages with the transmission component, thereby achieving axial restraint of the cutter barrel by the transmission component. This prevents the cutter barrel from easily separating from the transmission component after the barrel is separated from the main unit, which could cause the cutter barrel to fall onto the table and result in wear or even damage to the cutting edge on the cutter barrel. This ensures the connection stability between the cutter barrel and the transmission component. In addition, the transmission component can also transmit torque to the cutter barrel through the elastic buckle. It can transmit power while preventing the cutter barrel from separating from the transmission component. This dual-purpose design achieves functional integration, eliminating the need for an additional structure to restrain the cutter barrel, which helps to simplify the overall machine structure and reduce production costs.

[0006] In a preferred embodiment of a structurally stable food processing machine, the transmission part is a transmission groove formed by the recess of the side wall at the rear end of the blade barrel toward the front end, and the elastic buckle extends at least partially into the transmission groove and engages with the side wall of the transmission groove.

[0007] By setting the transmission part as a transmission groove formed by the side wall of the rear end of the tool barrel facing the front end, and the elastic buckle extending at least partially into the transmission groove and engaging with the side wall of the transmission groove, the elastic buckle can not only engage with the side wall of the transmission groove, but also limit the radial movement of the tool barrel and the transmission component by the limiting effect of the side wall of the transmission groove on the elastic buckle. This ensures the coaxiality of the transmission component, the tool barrel, and the motor shaft, thereby improving the stability of the tool barrel during rotation and preventing the tool barrel from wobbling during rotation due to poor coaxiality between the tool barrel and the transmission component.

[0008] In a preferred embodiment of a structurally stable food processing machine, the outer wall of the elastic buckle is provided with a first limiting protrusion, and the inner wall of the transmission groove is provided with a second limiting protrusion that engages with the first limiting protrusion.

[0009] By providing a first limiting protrusion on the outer wall of the elastic buckle and a second limiting protrusion on the inner wall of the transmission groove that engages with the first limiting protrusion, the elastic buckle can achieve axial positioning of the transmission component and the tool barrel through the contact between the first and second limiting protrusions when it is inserted into the transmission groove. This ensures the stability of the connection between the transmission component and the tool barrel. At the same time, the first and second limiting protrusions are simple to form and have a reliable fit, which helps to reduce production costs.

[0010] In a preferred embodiment of a structurally stable food processing machine, one of the outer wall of the elastic buckle and the inner wall of the transmission groove is provided with a third limiting protrusion, and the other of them is provided with a limiting groove that engages with the third limiting protrusion.

[0011] By providing a third limiting protrusion on one of the outer sidewall of the elastic buckle and the inner sidewall of the transmission groove, and a limiting groove on the other sidewall that engages with the third limiting protrusion, the third limiting protrusion engages with the limiting groove when the elastic buckle is inserted into the transmission groove, thereby achieving the engagement between the elastic buckle and the transmission groove and improving the stability of the connection between the tool barrel and the transmission component.

[0012] In a preferred embodiment of a structurally stable food processing machine, a third limiting protrusion is provided on the outer wall of the elastic buckle, a limiting groove is provided on the inner wall of the transmission groove, and the limiting groove has an anti-rotation surface at the front end of the blade barrel in the rotation direction that cooperates with the third limiting protrusion for limiting.

[0013] By providing an anti-rotation surface at the front end of the limiting groove in the rotation direction of the tool barrel, which cooperates with the third limiting protrusion, the third limiting protrusion can be engaged with the transmission groove in an elastic snap, and at the same time, the anti-rotation surface can cooperate with the third limiting protrusion to transmit torque to the tool barrel when the transmission component rotates. This achieves power transmission while preventing the tool barrel from separating from the transmission component.

[0014] In a preferred embodiment of a structurally stable food processing machine, the elastic buckle includes a locking part that engages with the transmission part and an operating part exposed outside the transmission part. The operating part can drive the locking part to move inward to disengage from the transmission part.

[0015] By configuring the elastic buckle to include a locking part that engages with the transmission part and an operating part exposed outside the transmission part, and by allowing the operating part to move the locking part inward to disengage from the transmission part, the user can press the operating part to disengage the locking part from the transmission part when it is necessary to separate the tool barrel from the transmission component, thereby achieving the separation of the tool barrel from the transmission component. This makes disassembly more convenient and quick, and improves the user experience.

[0016] In a preferred embodiment of a structurally stable food processing machine, the transmission component is further provided with a transmission structure that is in transmission cooperation with the transmission unit.

[0017] By incorporating a transmission structure that engages with the transmission unit, the transmission component can not only transmit torque to the blade cylinder via elastic latches but also achieve transmission connection through the transmission structure. This disperses the torque, enabling the motor to transmit greater torque to the blade cylinder, increasing the upper limit of torque transmission, and thus expanding the range of hardness that the food processor can handle.

[0018] In a preferred embodiment of a structurally stable food processing machine, the transmission component includes a connector with a resilient latch and a connecting shaft that drivesly connects the connector to the motor shaft; or,

[0019] The transmission component is equipped with a transmission cavity that is connected to the motor shaft of the motor.

[0020] By setting the transmission component to include a connector with an elastic buckle and a connecting shaft that is connected between the connector and the motor shaft, the connecting shaft and the connector can be formed of different materials. Preferably, the connecting shaft is made of metal so that it can withstand greater torque during torque transmission, avoid wear when transmitting torque with the motor shaft, and prevent relative sliding between the shaft and the motor shaft, thus ensuring the reliability of torque transmission.

[0021] By providing a transmission cavity in the transmission component that is connected to the motor shaft of the motor, the motor shaft can directly extend into the transmission cavity to drive the transmission component, resulting in a simpler structure and more reliable torque transmission.

[0022] In a preferred embodiment of a structurally stable food processing machine, multiple elastic buckles are spaced apart along the circumference of the transmission member, and at least two elastic buckles are arranged symmetrically along the radial direction of the transmission member.

[0023] By arranging multiple elastic clips spaced circumferentially along the transmission component, the transmission component can achieve a locking engagement with the tool barrel through these multiple clips, further enhancing the stability of the connection and improving torque transmission, enabling high-torque transmission. Furthermore, at least two elastic clips are symmetrically arranged radially along the transmission component, ensuring uniform radial force distribution when the transmission component connects to the tool barrel. This helps improve the coaxiality of the tool barrel and the transmission component, preventing wobble during tool barrel rotation caused by low coaxiality. Attached Figure Description

Detailed Implementation

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] 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.

[0035] like Figures 1 to 6 As shown, this utility model provides a food processing machine with a stable structure, including a main unit 1 with a built-in motor 5, a material cylinder 4 detachably connected to the main unit 1 and having a cutting chamber 41, a blade cylinder 3 that can be taken out and put into the cutting chamber 41 and is drivenly connected to the motor 5, and an end cover 2 that fixes the blade cylinder 3 in the cutting chamber 41. The rear end of the material cylinder 4 is connected to the main unit 1, and the front end is connected to the end cover 2. The food processing machine also includes a transmission component 6 that is driven between the blade cylinder 3 and the motor 5. The blade cylinder 3 has a transmission part on the side facing the transmission component 6, and the transmission component 6 has an elastic buckle 63 that engages with the transmission part.

[0036] This application configures the material cylinder 4 to be detachably connected to the main unit 1, and the blade cylinder 3 to be detachably connected to the cutting chamber 41. This allows the user to first detach the material cylinder 4 from the main unit 1 after using the food processing machine. During this process, the blade cylinder 3 also simultaneously separates from the cutting chamber 41, enabling cleaning of the material cylinder 4. Then, the blade cylinder 3 can be detached from the motor 5, allowing for deep cleaning of the blade cylinder 3. This ensures the cleanliness of both the blade cylinder 3 and the material cylinder 4, preventing the accumulation of dirt and even mold due to prolonged lack of deep cleaning. Simultaneously, a transmission component 6 is installed between the blade cylinder 3 and the motor 5, allowing the torque output by the motor 5 to be transmitted to the blade cylinder 3, thus enabling the rotation of the blade cylinder 3. Furthermore, the cutter barrel 3 has a transmission part on the side facing the transmission component 6. The transmission component 6 has an elastic buckle 63 that engages with the transmission part. When the cutter barrel 3 is connected to the transmission component 6, the elastic buckle 63 engages with the transmission component 6, thereby achieving axial limiting of the cutter barrel 3 by the transmission component 6. This prevents the cutter barrel 3 from losing its axial limiting after the material barrel 4 is separated from the main unit 1, which would cause the cutter barrel 3 to easily separate from the transmission component 6, resulting in the cutter barrel 3 falling onto the table and causing wear or even damage to the cutting edge on the cutter barrel 3. This ensures the connection stability between the cutter barrel 3 and the transmission component 6. In addition, the transmission component 6 can also transmit torque to the cutter barrel 3 through the elastic buckle 63. While realizing power transmission, it can also prevent the cutter barrel 3 from separating from the transmission component 6. This dual-purpose design achieves functional integration, eliminating the need for an additional structure to limit the cutter barrel 3, which helps to simplify the overall machine structure and reduce production costs.

[0037] It should be noted that this application does not specifically limit the structure of the transmission part. As a preferred embodiment of this application, such as Figure 3 , Figure 4 As shown, the transmission part is a transmission groove 31 formed by the recess of the rear side wall of the cutter barrel 3 toward the front end. The elastic buckle 63 extends at least partially into the transmission groove 31 and engages with the side wall of the transmission groove 31.

[0038] By setting the transmission part as a transmission groove 31 formed by the side wall of the rear end of the cutter barrel 3 being recessed towards the front end, and the elastic buckle 63 extending at least partially into the transmission groove 31 and engaging with the side wall of the transmission groove 31, the elastic buckle 63 extends into the transmission groove 31 to engage with the side wall of the transmission groove 31. At the same time, the side wall of the transmission groove 31 limits the elastic buckle 63 to achieve radial limitation of the cutter barrel 3 and the transmission component 6, thereby ensuring the coaxiality of the transmission component 6, the cutter barrel 3, and the motor shaft 51, thereby improving the stability of the cutter barrel 3 when rotating and avoiding the situation where the poor coaxiality of the cutter barrel 3 and the transmission component 6 causes it to wobble when rotating.

[0039] It should be further noted that this application does not specifically limit how the elastic buckle 63 achieves engagement with the side wall of the transmission groove 31, and it can be any of the following embodiments:

[0040] Example 1: As Figure 4 As shown, in this embodiment, the outer side wall of the elastic buckle 63 is provided with a first limiting protrusion 6311, and the inner side wall of the transmission groove 31 is provided with a second limiting protrusion 311 that engages with the first limiting protrusion 6311.

[0041] By providing a first limiting protrusion 6311 on the outer side wall of the elastic buckle 63 and a second limiting protrusion 311 on the inner side wall of the transmission groove 31 that engages with the first limiting protrusion 6311, the elastic buckle 63, when inserted into the transmission groove 31, achieves axial positioning of the transmission component 6 and the cutter barrel 3 through the abutment of the first limiting protrusion 6311 and the second limiting protrusion 311, ensuring the stability of the connection between the transmission component 6 and the cutter barrel 3. At the same time, the first limiting protrusion 6311 and the second limiting protrusion 311 are simple to form and have a reliable fit, which helps to reduce production costs.

[0042] Example 2: In this example, one of the outer sidewall of the elastic buckle 63 and the inner sidewall of the transmission groove 31 is provided with a third limiting protrusion, and the other of them is provided with a limiting groove that engages with the third limiting protrusion.

[0043] By providing a third limiting protrusion on one of the outer sidewall of the elastic buckle 63 and the inner sidewall of the transmission groove 31, and providing a limiting groove on the other sidewall that engages with the third limiting protrusion, the third limiting protrusion engages with the limiting groove when the elastic buckle 63 extends into the transmission groove 31, thereby achieving the engagement between the elastic buckle 63 and the transmission groove 31 and improving the stability of the connection between the tool barrel 3 and the transmission component 6.

[0044] Furthermore, the third limiting protrusion is provided on the outer wall of the elastic buckle 63, the limiting groove is provided on the inner wall of the transmission groove 31, and the limiting groove has an anti-rotation surface at the front end of the blade barrel 3 in the rotation direction that cooperates with the third limiting protrusion for limiting.

[0045] By providing an anti-rotation surface at the front end of the limiting groove in the rotation direction of the tool barrel 3, which cooperates with the third limiting protrusion, the third limiting protrusion can be engaged with the transmission groove 31 while the elastic buckle 63 is engaged with the transmission groove 31. At the same time, the anti-rotation surface can also be engaged with the third limiting protrusion to transmit torque to the tool barrel 3 when the transmission component 6 rotates. This achieves power transmission while preventing the tool barrel 3 from disengaging from the transmission component 6.

[0046] As a preferred embodiment of this application, such as Figure 4As shown, the elastic buckle 63 includes a locking part 631 that engages with the transmission part and an operating part 632 exposed in the transmission part. The operating part 632 can drive the locking part 631 to move inward to disengage from the transmission part.

[0047] By configuring the elastic buckle 63 to include a locking part 631 that engages with the transmission part and an operating part 632 exposed to the transmission part, and by allowing the operating part 632 to move the locking part 631 inward to disengage from the transmission part, the user can press the operating part 632 to disengage the locking part 631 from the transmission part when it is necessary to separate the tool barrel 3 from the transmission component 6, thereby achieving the separation of the tool barrel 3 from the transmission component 6. This makes disassembly more convenient and quick, and improves the user experience.

[0048] Specifically, such as Figure 4 As shown, the elastic buckle 63 is engaged with the transmission part by a horizontal plate, and the horizontal plate is provided with a first limiting protrusion 6311. The operating part 632 is exposed to the transmission part and has an outwardly extending flange 6321 at the end of the horizontal plate, which helps the user to operate and press the operating part 632.

[0049] It should be noted that this application does not specifically limit the torque transmission method between the transmission component 6 and the transmission part. It can be that torque transmission is achieved only by the snap-fit ​​between the elastic buckle 63 and the transmission part. Alternatively, as a preferred embodiment of this application, the transmission component 6 is also provided with a transmission structure that is in transmission cooperation with the transmission part.

[0050] By providing a transmission structure that works in conjunction with the transmission unit in the transmission component 6, the transmission component 6 can not only transmit torque to the blade barrel 3 through the elastic buckle 63, but also achieve transmission connection through the transmission structure, thereby dispersing the torque so that the motor 5 can transmit a larger torque to the blade barrel 3, increasing the upper limit of torque transmission, and thus increasing the hardness range of food processing machine for food ingredients.

[0051] It should be noted that this application does not specifically limit the transmission structure; as one preferred embodiment of this application, such as... Figure 5 , Figure 6 As shown, the transmission structure includes a transmission rib 64 located on either the transmission member 6 or the transmission part, and a transmission groove 32 on the other part that engages with the transmission rib 64. More preferably, the transmission rib 64 is located on the transmission member 6, and the transmission groove 32 is located on the transmission part. When the cutter barrel 3 is assembled with the transmission member 6, the elastic buckle 63 engages with the transmission member 6, while the transmission rib 64 extends into the transmission groove 32 to abut, thereby transmitting torque.

[0052] It should be noted that this application does not specifically limit how the transmission component 6 cooperates with the motor shaft 51, and it can be any of the following embodiments:

[0053] Example 1: As Figure 3 As shown, in this embodiment, the transmission component 6 includes a connector 62 with an elastic buckle 63 and a connecting shaft 61 that is transmissionally connected between the connector 62 and the motor shaft 51 of the motor 5.

[0054] By configuring the transmission component 6 as a connector 62 with an elastic buckle 63 and a connecting shaft 61 that is connected between the connector 62 and the motor shaft 51 of the motor 5, the connecting shaft 61 and the connector 62 can be formed of different materials. Preferably, the connecting shaft 61 is made of metal so that it can withstand greater torque during torque transmission, avoid wear when transmitting torque with the motor shaft 51, and prevent relative sliding between the shaft and the motor shaft 51, thus ensuring the reliability of torque transmission.

[0055] Example 2: In this example, the transmission component 6 is provided with a transmission cavity that is connected to the motor shaft 51 of the motor 5.

[0056] By providing a transmission cavity in the transmission component 6 that is connected to the motor shaft 51 of the motor 5, the motor shaft 51 can be directly inserted into the transmission cavity to drive the transmission component 6. This results in a simpler structure and more reliable torque transmission.

[0057] As a preferred embodiment of this application, such as Figure 5 As shown, multiple elastic buckles 63 are provided at intervals along the circumference of the transmission member 6, and at least two elastic buckles 63 are arranged symmetrically along the radial direction of the transmission member 6.

[0058] By arranging multiple elastic latches 63 at intervals along the circumference of the transmission member 6, the transmission member 6 can achieve a locking engagement with the tool barrel 3 through multiple elastic latches 63, further improving the stability of the connection between the two and also enhancing torque transmission to achieve high torque transmission. Furthermore, at least two elastic latches 63 are symmetrically arranged radially along the transmission member 6, ensuring uniform radial force distribution when the transmission member 6 connects with the tool barrel 3. This helps improve the coaxiality between the tool barrel 3 and the transmission member 6, preventing the tool barrel 3 from wobbling during rotation due to low coaxiality.

[0059] 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.
