Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with stable operation. Background Art

[0002] Existing food processing machines such as juicers usually include a main unit with a built-in motor and a detachable cup assembly disposed above the main unit. The cup assembly includes a knife seat with a crushing device on the top and a crushing cup covered on the knife seat. The crushing device is connected to the motor by transmission. When the user uses the food processing machine to process food, the food is first placed in the crushing cup, and then the knife seat is covered on the open part of the crushing cup, and then the entire cup assembly is inverted and installed on the main unit, and the main unit crushing device is started to rotate at high speed driven by the motor to achieve food processing. In order to ensure that the main unit can be started only after the cup assembly and the main unit are in place, the Chinese utility model patent CN210169854U discloses a safe and reliable food processing machine, which is provided with a safety switch electrically connected to the motor in the machine base. When the knife seat is installed in place, the trigger frame of the safety switch is triggered so that the motor can be started and food processing can be performed. Although the above scheme can ensure that the main unit can be started only after the cup body assembly is in place, in actual use, the user needs to remove the cup body assembly from the main unit after processing the food. However, the lower part of the knife seat is embedded in the main unit, and it is not convenient for the user to directly hold the knife seat and unscrew it to remove it. Therefore, some users will mistakenly operate by rotating the crushing cup to unscrew the entire cup body assembly. However, since the knife seat and the main unit are more firmly matched, when the crushing cup is subjected to force, the crushing cup will be relatively displaced relative to the knife seat, causing the crushing cup to unscrew relative to the knife seat, thereby causing the food in the crushing cup to leak out, seriously affecting the consumer experience. Utility Model Content

[0003] The utility model aims to provide a food processor with stable operation, so as to solve the problem that the grinding cup is unscrewed relative to the knife seat due to user's misoperation in the existing food processor, resulting in leakage of food in the grinding cup.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with stable operation, including a main machine with a built-in motor and a detachable cup body assembly arranged above the main machine, the cup body assembly including a knife seat with a crushing device on the top and a crushing cup covered on the knife seat, the crushing device is connected to the motor by transmission, the knife seat is provided with an axially movable follower, an active part is provided at the top of the main machine, and a stop rib is convexly provided on the outer side of the bottom end of the crushing cup. After the cup body assembly is installed to the main machine, the active part drives the follower to move upward and cooperates with the stop rib to stop rotation.

[0005] The present application provides an axially movable follower on the knife seat, an active part on the top of the main machine, and a stop rib convexly provided on the outer side of the bottom end of the grinding cup, so that after the grinding cup and the knife seat are combined into a cup body assembly and installed on the main machine, the active part can drive the follower to move upward, and the top end of the follower cooperates with the stop rib to stop rotation, thereby realizing circumferential limitation of the grinding cup. On the one hand, after the cup body assembly is installed in place, the stop rib is limited by the follower to prevent the user from accidentally holding the grinding cup and rotating it during the process of detaching the cup body assembly from the main machine after using the food processor, causing the grinding cup to rotate relative to the knife seat The invention can prevent the food from leaking out of the machine, so that the grinding cup can be separated from the knife holder only when the knife holder and the main machine are unscrewed, the active part is separated from the driven part, and the driven part is reset and loses the anti-rotation limit of the anti-rotation rib, thereby ensuring the smooth transportation of the food; on the other hand, when the user holds the grinding cup to detach it, the anti-rotation rib and the driven part cooperate to drive the knife holder to rotate together and separate from the main machine. Compared with the existing method of only being able to detach the cup body assembly by holding the knife holder, the user's holding area is larger, so that the user can more easily detach the cup body assembly from the main machine, thereby improving the user experience. In addition, with the anti-rotation cooperation of the driven part and the anti-rotation rib, the stability of the connection between the knife holder and the grinding cup is improved, avoiding the situation in which the grinding cup and the knife holder vibrate relative to each other during the food processing to generate large vibration noise, which helps to improve the noise reduction effect.

[0006] In a preferred implementation of a food processor with stable operation, a mounting groove for mounting a crushing cup is provided on the upper portion of the knife seat, and a limiting rib is provided on the top of the follower. After the cup body assembly is installed to the main machine, the limiting rib extends into the mounting groove and cooperates with the anti-rotation rib.

[0007] By providing a mounting groove for installing the crushing cup on the upper part of the knife holder, after the user assembles the crushing cup and the knife holder, the crushing cup can effectively improve the reliability of the position of the crushing cup with the help of the limiting of the mounting groove, and improve the stability of the connection and cooperation between the two. At the same time, a limiting rib is provided on the top of the driven part. After the cup body assembly is installed on the main machine, the limiting rib extends into the mounting groove and cooperates with the anti-rotation rib to realize the anti-rotation limit of the driven part on the anti-rotation rib, thereby ensuring the reliability of the driven part limiting the crushing cup.

[0008] In a preferred implementation of a food processor with stable operation, a ring rib matching the inner wall of the mounting groove is provided at the bottom of the grinding cup, an outer wall of the ring rib is provided with an external thread, and a rotation-stopping rib is provided below the external thread.

[0009] By providing a ring rib that matches the inner wall of the installation groove at the bottom of the grinding cup, and providing an external thread on the outer wall of the ring rib, when the grinding cup matches with the knife seat, the external thread of the grinding cup and the internal thread of the installation groove are threadedly matched, which helps to further improve the stability of the connection between the two. At the same time, the external thread protrudes from the outer wall of the ring rib, thereby providing lateral space for the anti-rotation rib, avoiding the interference between the anti-rotation rib and the inner wall of the installation groove, which makes the grinding cup unable to be installed. At the same time, the anti-rotation rib is arranged below the external thread, so that the anti-rotation rib is closer to the knife seat, so that the distance that the driven part moves upward can be reduced, avoiding the situation that the anti-rotation rib is far from the knife seat and the driven part needs to move upward a large distance, causing the active part to protrude more. In addition, the interference between the anti-rotation rib and the external thread is avoided, ensuring the smooth installation of the grinding cup.

[0010] In a preferred implementation of a food processor with stable operation, a sealing ring is provided around the mounting groove, the mouth of the grinding cup abuts against the sealing ring, and the sealing ring is provided with an escape opening for the limiting rib to extend.

[0011] By providing a sealing ring around the installation groove, and the cup mouth of the crushing cup abuts against the sealing ring, after the crushing cup is installed in place, the abutment between the cup mouth and the sealing ring can improve the sealing performance of the connection between the crushing cup and the installation groove, thereby effectively avoiding the gap between the cup mouth and the installation groove, which may cause the slurry to overflow to the outside, and ensure the stability of food processing. At the same time, the shock absorption of the sealing ring can avoid the collision and noise between the crushing cup and the installation groove during food processing, which helps to further reduce the noise. In addition, the sealing ring is provided with an avoidance opening for the limit rib to extend, so as to ensure that the limit rib can be smoothly extended and cooperate with the anti-rotation rib to stop rotation, and avoid the interference between the sealing ring and the limit rib, which may cause the limit rib to be unable to extend and cause the cup body to stop rotation failure.

[0012] In a preferred implementation of a food processor with stable operation, the follower includes an annular pressure ring fixed to the bottom end of the knife seat, and the bottom end of the annular pressure ring is provided with a plurality of protrusions extending toward the main machine, and the protrusions are used to cooperate and connect with the active part.

[0013] By setting the follower to include an annular pressure ring fixed to the bottom end of the knife seat, the knife seat can be adapted to the main machine through the annular pressure ring after being assembled in place, avoiding the situation where the follower is set as an irregular part, which causes the need to set up additional space between the knife seat and the main machine to accommodate the follower, ensuring the compactness of the whole machine structure and reducing the space occupied by the whole machine. At the same time, the bottom end of the annular pressure ring is provided with a plurality of convex parts extending toward the main machine, and the convex parts are used to cooperate with the active part to connect, so that after the knife seat is assembled in place, the annular pressure ring can be subjected to a uniform upward driving force in the circumferential direction, thereby ensuring that the annular pressure ring moves upward smoothly, avoiding the situation where only one convex part causes the annular pressure ring to be unevenly stressed and tilted, causing the knife seat to be stuck or even unable to be assembled in place, and ensuring the smoothness of the knife seat assembly process.

[0014] In a preferred implementation of a food processor with stable operation, the convex portion is a plate-shaped structure, and the convex portions are symmetrically distributed along the center of the annular pressure ring.

[0015] By distributing the protrusions symmetrically along the center of the annular pressure ring, the force uniformity of the annular pressure ring when the protrusions are subjected to force is further improved, ensuring that it can be subjected to force in multiple directions and move upward synchronously, further ensuring the stability and smoothness of the upward movement of the annular pressure ring.

[0016] In a preferred implementation of a food processor with stable operation, the active portion includes a protrusion extending upward from the top wall of the main machine.

[0017] By including a protrusion extending upward from the top wall of the main machine in the active part, after the knife seat is installed in place, the protrusion lifts the driven member to drive the driven member to move upward and realizes the anti-rotation cooperation with the anti-rotation rib. In addition, the protrusion is simple to form and does not require much modification to the original model, which helps to reduce the modification cost and production cost.

[0018] In a preferred implementation of a food processor with stable operation, a guide column extending downward is provided on the bottom wall of the knife seat, a spring is sleeved on the outer side of the guide column, a follower is provided with a guide hole matching the guide column, a limit piece is provided at the bottom end of the guide column, one end of the spring abuts against the limit piece, and the other end abuts against the follower.

[0019] By providing the follower with a guide hole that cooperates with the guide column, and providing a limiter at the bottom of the guide column, one end of the spring abuts against the limiter, and the other end abuts against the follower, so that after the follower and the knife seat are installed in place, the follower can move back and forth on the guide column, and can also be reset under the elastic force of the spring, so that after the knife seat and the host are installed in place, the follower can move upward along the guide column under the drive of the active part, ensuring the uniqueness of the moving trajectory of the follower, thereby improving its smoothness of movement. When the user detaches the knife seat from the host, the follower moves downward under the elastic force of the reset member, so that the top of the follower falls off the anti-rotation rib, thereby ensuring that the crushing cup can be smoothly detached from the knife seat, effectively avoiding the situation where the follower is stuck and cannot be reset, resulting in the crushing cup being unable to be detached from the knife seat.

[0020] In a preferred implementation of a food processing machine with stable operation, the main machine is provided with a micro switch and a switch connecting rod for triggering the micro switch. After the cup body assembly is installed to the main machine, the knife seat drives the switch connecting rod to trigger the micro switch.

[0021] By equipping the main machine with a micro switch, after the cup body assembly is installed to the main machine, the knife holder drives the switch connecting rod to trigger the micro switch, so that the main machine can start working only after the knife holder is installed in place, effectively avoiding the situation where the main machine can run without the knife holder being installed in place, causing the coupling connecting the knife holder and the main machine to slip or get stuck, thereby ensuring the stability of the transmission between the main machine and the knife holder and improving the stability of the whole machine operation.

[0022] In a preferred implementation of a food processing machine with stable operation, the follower is provided with a convex portion extending toward the main machine, and after the cup body assembly is installed to the main machine, the convex portion drives the switch connecting rod to move downward and trigger the micro switch.

[0023] By providing the follower with a convex portion extending toward the main unit, after the cup body assembly is installed to the main unit, the convex portion drives the switch connecting rod to move downward and triggers the micro switch, so that after the knife holder is installed in place, the follower can not only move upward under the drive of the switch connecting rod, but the switch connecting rod can also move downward under the drive of the convex portion, thereby realizing the functional integration of the two and eliminating the need to set up other structural components to realize the drive of the follower and the switch connecting rod, which helps to simplify the structure of the whole machine and reduce the production cost.

DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0036] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0037] like Figures 1 to 8 As shown, the utility model provides a food processing machine with stable operation, including a main machine 1 with a built-in motor 11 and a detachable cup body assembly arranged above the main machine 1, the cup body assembly includes a knife seat 3 with a crushing device 10 on the top and a crushing cup 2 covered on the knife seat 3, the crushing device 10 is transmission connected to the motor 11, the knife seat 3 is provided with an axially movable follower 4, an active part 12 is provided at the top of the main machine 1, and a stop rib 21 is convexly provided on the outer side of the bottom end of the crushing cup 2. After the cup body assembly is installed to the main machine 1, the active part 12 drives the follower 4 to move upward and cooperates with the stop rib 21 to stop rotation.

[0038] The present application provides an axially movable follower 4 on the knife holder 3, an active part 12 on the top of the main machine 1, and a stop rib 21 protruding from the outer side of the bottom end of the crushing cup 2, so that after the crushing cup 2 and the knife holder 3 are combined into a cup body assembly and installed on the main machine 1, the active part 12 can drive the follower 4 to move upward, and the top of the follower 4 cooperates with the stop rib 21 to stop rotation, thereby realizing the circumferential limitation of the crushing cup 2. On the one hand, after the cup body assembly is installed in place, the stop rib 21 is limited by the follower 4 to prevent the user from accidentally holding the crushing cup 2 and rotating it during the process of detaching the cup body assembly from the main machine 1 after using the food processor, causing the crushing cup 2 to rotate relative to the main machine 1. The rotation of the knife seat 3 causes the leakage of food, so that the crushing cup 2 can only be separated from the knife seat 3 when the knife seat 3 and the main machine 1 are unscrewed, the active part 12 is separated from the driven part 4, and the driven part 4 is reset to lose the anti-rotation limit of the anti-rotation rib 21, thereby ensuring the smooth transportation of food; on the other hand, when the user holds the crushing cup 2 to detach it, the anti-rotation rib 21 cooperates with the driven part 4 to drive the knife seat 3 to rotate together and separate from the main machine 1. Compared with the existing method of only being able to detach the cup body assembly by holding the knife seat 3, the user's holding area is larger, so that the user can more easily detach the cup body assembly from the main machine 1, thereby improving the user experience. In addition, with the anti-rotation cooperation of the driven part 4 and the anti-rotation rib 21, the stability of the connection between the knife seat 3 and the crushing cup 2 is improved, and the relative vibration between the crushing cup 2 and the knife seat 3 during the food processing process is avoided to generate large vibration noise, which helps to improve the noise reduction effect.

[0039] As a preferred implementation of the present application, Figure 2 As shown, a mounting groove 31 for mounting the grinding cup 2 is provided on the upper portion of the knife seat 3, and a limiting rib 41 is provided on the top of the follower 4. After the cup body assembly is installed to the main machine 1, the limiting rib 41 extends into the mounting groove 31 and cooperates with the anti-rotation rib 21.

[0040] By providing a mounting groove 31 for mounting the crushing cup 2 on the upper part of the knife holder 3, after the user assembles the crushing cup 2 and the knife holder 3, the crushing cup 2 can effectively improve the position reliability of the crushing cup 2 with the help of the mounting groove 31, and improve the stability of the connection and cooperation between the two. At the same time, a limiting rib 41 is provided on the top of the follower 4. After the cup body assembly is installed on the host 1, the limiting rib 41 extends into the mounting groove 31 and cooperates with the anti-rotation rib 21, so that the follower 4 stops the rotation of the anti-rotation rib 21, and ensures the reliability of the follower 4 limiting the crushing cup 2.

[0041] It should be noted that the present application does not specifically limit the matching mode between the grinding cup 2 and the knife holder 3. As a preferred embodiment of the present application, Figure 2 As shown, the bottom of the grinding cup 2 is provided with an annular rib 22 that matches the inner wall of the mounting groove 31 , the outer wall of the annular rib 22 is provided with an external thread 221 , and the anti-rotation rib 21 is provided below the external thread 221 .

[0042] By providing an annular rib 22 that matches the inner wall of the mounting groove 31 at the bottom of the pulverizing cup 2, and providing an external thread 221 on the outer wall of the annular rib 22, when the pulverizing cup 2 matches the knife seat 3, the external thread 221 of the pulverizing cup 2 and the internal thread of the mounting groove 31 are threadedly matched, which helps to further improve the stability of the connection and matching between the two. At the same time, the external thread 221 protrudes from the outer wall of the annular rib 22, so as to provide a lateral space for the anti-rotation rib 21, and avoid the situation that the anti-rotation rib 21 and the inner wall of the mounting groove 31 interfere with each other, resulting in the pulverizing cup 2 being unable to be installed. At the same time, the anti-rotation rib 21 is arranged below the external thread 221, so that the anti-rotation rib 21 is closer to the knife seat 3, so that the distance that the driven member 4 moves upward can be reduced, and the situation that the anti-rotation rib 21 is far away from the knife seat 3 and the driven member 4 needs to move upward a large distance, resulting in a large protrusion of the active part 12, is avoided. And the interference between the anti-rotation rib 21 and the external thread 221 is avoided, ensuring the smooth installation of the pulverizing cup 2.

[0043] As a preferred embodiment of this embodiment, Figure 8 As shown, a sealing ring 9 is provided around the installation groove 31 , the mouth of the grinding cup 2 abuts against the sealing ring 9 , and the sealing ring 9 is provided with an escape opening 91 for the limiting rib 41 to extend out.

[0044] By providing a sealing ring 9 around the mounting groove 31, and the cup mouth of the crushing cup 2 abuts against the sealing ring 9, after the crushing cup 2 is installed in place, the abutment between the cup mouth and the sealing ring 9 can improve the sealing performance of the connection between the crushing cup 2 and the mounting groove 31, thereby effectively avoiding the gap between the cup mouth and the mounting groove 31, which can cause the slurry to overflow to the outside, and ensure the stability of food processing. At the same time, the shock absorption of the sealing ring 9 can avoid the collision and noise between the crushing cup 2 and the mounting groove 31 during food processing, which helps to further reduce the generation of noise. In addition, the sealing ring 9 is provided with an avoidance opening 91 for the limit rib 41 to extend, ensuring that the limit rib 41 can be smoothly extended and cooperate with the anti-rotation rib 21 to prevent the seal ring 9 from interfering with the limit rib 41, resulting in the limit rib 41 being unable to extend and causing the cup body to fail to stop rotating.

[0045] It should be noted that the present application does not specifically limit the structure of the follower 4. As a preferred embodiment of the present application, Figure 4 As shown, the follower 4 includes an annular pressure ring fixed to the bottom end of the knife seat 3, and the bottom end of the annular pressure ring is provided with a plurality of protrusions 42 extending toward the main machine 1, and the protrusions 42 are used for matching and connecting with the active part 12.

[0046] By setting the follower 4 to include an annular pressure ring fixed to the bottom end of the knife seat 3, the knife seat 3 can be adapted to the host 1 through the annular pressure ring after being assembled in place, avoiding the situation where the follower 4 is set as an irregular part, which causes the need to set up additional space between the knife seat 3 and the host 1 to accommodate the follower 4, ensuring the compactness of the whole machine structure and reducing the space occupied by the whole machine. At the same time, the bottom end of the annular pressure ring is provided with a plurality of protrusions 42 extending toward the host 1, and the protrusions 42 are used to cooperate with the active part 12, so that after the knife seat 3 is assembled in place, the annular pressure ring can be subjected to a uniform upward driving force in the circumferential direction, thereby ensuring that the annular pressure ring moves upward smoothly, avoiding the situation where only one protrusion 42 causes the annular pressure ring to be unevenly stressed and tilted, causing the knife seat 3 to get stuck or even unable to be assembled in place during assembly, and ensuring the smoothness of the assembly process of the knife seat 3.

[0047] Furthermore, if Figure 4 As shown, the protrusion 42 is a plate-like structure, and the protrusion 42 is symmetrically distributed along the center of the annular pressure ring.

[0048] By symmetrically distributing the protrusions 42 along the center of the annular pressure ring, the force uniformity of the annular pressure ring when the protrusions 42 are subjected to force is further improved, ensuring that it can be subjected to force in multiple directions and move upward synchronously, further ensuring the stability and smoothness of the upward movement of the annular pressure ring.

[0049] As a preferred embodiment of the present application, Figure 3 As shown, the active portion 12 includes a protrusion extending upward from the top wall of the host 1.

[0050] By making the active part 12 include a protrusion extending upward from the top wall of the main machine 1, after the knife seat 3 is installed in place, the protrusion pushes up the follower 4 to drive the follower 4 to move upward, and realizes the anti-rotation cooperation with the anti-rotation rib 21. In addition, the protrusion is simple to form and does not require much modification to the original model, which helps to reduce the modification cost and production cost.

[0051] As a preferred embodiment of the present application, Figure 7 As shown, the bottom wall of the knife seat 3 is provided with a guide column 32 extending downward, a spring 7 is sleeved on the outer side of the guide column 32, the follower 4 is provided with a guide hole 43 cooperating with the guide column 32, and a limit piece 8 is provided at the bottom end of the guide column 32, one end of the spring 7 abuts against the limit piece 8, and the other end abuts against the follower 4.

[0052] By providing the follower 4 with a guide hole 43 that cooperates with the guide column 32, and providing a limiter 8 at the bottom end of the guide column 32, one end of the spring 7 abuts against the limiter 8, and the other end abuts against the follower 4, so that after the follower 4 and the knife seat 3 are installed in place, the follower 4 can move back and forth on the guide column 32, and can also be reset under the elastic force of the spring 7, so that after the knife seat 3 and the host 1 are installed in place, the follower 4 can move upward along the guide column 32 under the drive of the active part 12, ensuring the uniqueness of the moving trajectory of the follower 4, thereby improving its smoothness of movement. When the user detaches the knife seat 3 from the host 1, the follower 4 moves downward under the elastic force of the reset member, so that the top end of the follower 4 and the anti-rotation rib 21 fall off, thereby ensuring that the crushing cup 2 can be smoothly detached from the knife seat 3, effectively avoiding the situation where the follower 4 is stuck and cannot be reset, resulting in the crushing cup 2 being unable to be detached from the knife seat 3.

[0053] As a preferred embodiment of the present application, Figure 2 As shown, the host 1 is provided with a micro switch 6 and a switch connecting rod 5 for triggering the micro switch 6 . After the cup body assembly is installed on the host 1 , the knife seat 3 drives the switch connecting rod 5 to trigger the micro switch 6 .

[0054] By providing the main machine 1 with a micro switch 6, after the cup body assembly is installed to the main machine 1, the knife seat 3 drives the switch connecting rod 5 to trigger the micro switch 6, so that the main machine 1 can start working only after the knife seat 3 is installed in place, effectively avoiding the main machine 1 from running when the knife seat 3 is not installed in place, causing the coupling of the knife seat 3 and the main machine 1 to slip or get stuck, thereby ensuring the stability of the transmission between the main machine 1 and the knife seat 3 and improving the stability of the whole machine operation.

[0055] Furthermore, if Figure 2 As shown, the follower 4 is provided with a protrusion 42 extending toward the host 1 . After the cup assembly is installed on the host 1 , the protrusion 42 drives the switch connecting rod 5 to move downward and triggers the micro switch 6 .

[0056] By providing the follower 4 with a protrusion 42 extending toward the main unit 1, after the cup body assembly is installed to the main unit 1, the protrusion 42 drives the switch connecting rod 5 to move downward and triggers the micro switch 6, so that after the knife holder 3 is installed in place, the follower 4 can not only move upward under the drive of the switch connecting rod 5, but also move downward under the drive of the protrusion 42, thereby realizing the functional integration of the two, eliminating the need to set up other structural components to realize the drive of the follower 4 and the switch connecting rod 5, which helps to simplify the structure of the whole machine and reduce the production cost.
