Detailed Implementation

[0038] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0039] Please see Figures 1 to 10 As shown, this utility model provides a multi-layered safety protection structure for a high-speed juicer. By integrating multiple safety protection measures, it ensures comprehensive protection for the user during the operation of the juicer. The safety protection structure includes a base 1, a blade assembly 2 housed within the base 1, and an upper cover 3 that cooperates with the blade assembly 2. The blade assembly 2 consists of a drive motor 21, a control module electrically connected to the drive motor 21, and a juicing blade 22 connected to the output end of the drive motor 21. The upper cover 3 covers the juicing blade 22, ensuring that the blade remains closed during operation. The safety protection structure further includes a linkage control mechanism 4 and a fastening mechanism 5, which, through precise design, ensure that the juicing blade 22 can only begin operation when the upper cover 3 is fully fastened.

[0040] To prevent safety hazards such as accidental start-up and exposed blades during the use of high-speed juicers, this invention addresses these issues through a multi-layered safety protection structure. Specifically, the linkage control mechanism 4 works in conjunction with the upper cover 3 and the control module to ensure that the juicer will only start after the upper cover 3 is correctly installed and secured. Furthermore, when the securing mechanism 5 is released, the linkage control mechanism 4 sends a stop signal, causing the drive motor 21 to stop working, thereby avoiding the risk of exposed blades.

[0041] The blade assembly 2 housed within the base 1 includes a drive motor 21 and a juicing blade 22. The drive motor 21 is connected to the juicing blade 22 via a control module. The upper cover 3 covers the juicing blade 22 and is fastened to the base 1 via a fastening mechanism 5. A linkage control mechanism 4 works in conjunction with the upper cover 3 and the control module to ensure that after the upper cover 3 is correctly installed, the control module receives a start signal, and the drive motor 21 begins operation. When the upper cover 3 is not correctly installed or is removed, the control module receives a stop signal, and the drive motor 21 stops operating.

[0042] The multiple safety protection structure of the high-speed juicer realizes effective protection of the juicing knife 22 through the cooperation of the linkage control mechanism 4, the fastening mechanism 5 and the control module. The linkage control mechanism 4 comprises a first pressing block 41 arranged on the upper cover body 3, a moving rod 42 arranged on the base 1 in a reciprocating manner and a micro switch 43 arranged in the base 1. After the upper cover body 3 is fastened and matched with the base 1 through the fastening mechanism 5, the first pressing block 41 moves downward to abut against the contact of the micro switch 43, and the micro switch 43 sends a starting signal to the control module. The fastening mechanism 5 comprises a fastening rod 51 arranged on the base 1 in a rotating manner and a fastening part 52 arranged on the upper cover body 3, and the fastening part 52 has a first clamping groove 521 for accommodating the fastening rod 51, an arc-shaped guide surface 522 and a stop block 523. The fastening rod 51 rotating in a forward direction presses the upper cover body 3 in the process of abutting against the guide surface and entering the first clamping groove 521, drives the linkage control mechanism 4 to move forward, and the fastening rod 51 rotating in a reverse direction moves out of the first clamping groove 521, so that the linkage control mechanism 4 moves reversely.

[0043] Compared with the prior art, the multiple safety protection is realized through the cooperation of the linkage control mechanism 4 and the fastening mechanism 5. The upper cover detection device or the mechanical limit switch in the prior art can only provide single protection function, while the multiple safety protection structure of the present application ensures that the juicer can provide comprehensive and reliable protection in different operating states. In addition, through the regulation and control of the control module, accurate control of the driving motor 21 is realized, and the safety performance of the juicer is further improved.

[0044] In actual use, when the upper cover body 3 is arranged above the juicing knife 22 and fastened and matched with the base 1 through the fastening mechanism 5, the linkage control mechanism 4 moves forward, sends a starting signal to the control module, and the control module regulates and controls the driving motor 21 to drive the juicing knife 22 to rotate for juicing. When the fastening mechanism 5 is released, the linkage control mechanism 4 moves reversely, sends a stop signal to the control module, and the control module regulates and controls the driving motor 21 to stop working. Thus, effective protection of the juicing knife 22 area is realized, and safety hazards such as misoperation and exposed knife are avoided.

[0045] The multiple safety protection structure not only improves the safety of the juicer, but also improves the user experience. Through the cooperation of the linkage control mechanism 4, the fastening mechanism 5 and the control module, the safety of the juicer in normal use and abnormal state is ensured. Specifically, the linkage control mechanism 4 ensures that the juicer can only be started after the upper cover body 3 is correctly installed and fastened through the cooperation of the first pressing block 41, the moving rod 42 and the micro switch 43. The fastening mechanism 5 ensures that the upper cover body 3 can be stably fixed after being correctly installed, avoiding the safety hazard caused by loosening. Finally, through the regulation of the control module, the precise control of the driving motor 21 is realized, further improving the safety performance of the juicer.

[0046] Specifically, the linkage control mechanism 4 includes a first pressing block 41 arranged on the upper cover body 3, a moving rod 42 reciprocally arranged on the base 1, and a micro switch 43 arranged in the base 1 and linked with the moving rod 42. The micro switch 43 is electrically connected with the control module. After the upper cover body 3 is fastened with the base 1 through the fastening mechanism 5, the first pressing block 41 moves downward to touch the contact of the micro switch 43, and the micro switch 43 sends a start signal to the control module under the touch of the moving rod 42.

[0047] The linkage control mechanism 4 realizes the downward movement of the moving rod 42 to touch the contact of the micro switch 43 after the upper cover body 3 is fastened with the base 1, and then sends a start signal to the control module through the first pressing block 41 arranged on the upper cover body 3, the moving rod 42 on the base 1 and the micro switch 43 in the base 1. This design ensures that the juicer can only be started after the upper cover body 3 is correctly installed and fastened, avoiding the risk of accidental start. The moving rod 42 sends a start signal to the control module under the action of the micro switch 43, ensuring the safety of the operation.

[0048] In actual production, the first pressing block 41 can be connected with the upper cover body 3 through a spring or other elastic elements to ensure that it can accurately trigger the moving rod 42 during fastening. The moving rod 42 can be made of high-strength material to ensure its durability in multiple uses. The micro switch 43 can choose a model with high sensitivity to ensure accurate transmission of the start signal. As a preferred embodiment, the contact of the micro switch 43 can be made of metal material to improve the wear resistance and service life of the contact.

[0049] The present scheme solves the problems of accidental start and improper operation of the juicer in the prior art through the design of the linkage control mechanism 4. Compared with the prior art, the design of the present scheme provides a safer and more reliable start mechanism, ensuring that the juicer can only be started after the upper cover body 3 is correctly installed and fastened, thereby effectively preventing the accidental start and exposure of the juicing knife 22 and improving the safety during use.

[0050] Specifically, the fastening mechanism 5 includes a fastening rod 51 rotatably arranged on the base 1 and a fastening portion 52 arranged on the upper cover body 3, the fastening portion 52 having a first clamping groove 521 for accommodating the fastening rod 51, an arc-shaped guide surface 522 arranged on one side of the first clamping groove 521, and a stop block 523 arranged on the other side of the first clamping groove 521; the first clamping groove 521 is arranged in an arc shape; the fastening rod 51 rotates in a forward direction, and in the process of entering the first clamping groove 521 against the guide surface, the upper cover body 3 is pressed down to drive the linkage control mechanism 4 to move forward; the fastening rod 51 rotates in a reverse direction, and moves out of the first clamping groove 521, so that the linkage control mechanism 4 moves reversely.

[0051] Most existing juicers have basic upper cover detection devices or mechanical limit switches, but these protective measures are often limited to single structures, have a narrow protective coverage range, and have limited reliability, and cannot comprehensively and effectively protect key parts during juicing.

[0052] The scheme of the present application realizes the stable connection of the upper cover body 3 and the base 1 by arranging the fastening mechanism 5, and controls the driving motor 21 through the linkage control mechanism 4. When the fastening rod 51 rotates, it can enter the first clamping groove 521 through the arc-shaped guide surface 522, and in this process, the upper cover body 3 is pressed down to drive the linkage control mechanism 4 to move forward, thereby sending a start signal to the control module to start the driving motor 21 for juicing. When the fastening rod 51 rotates reversely and moves out of the first clamping groove 521, the linkage control mechanism 4 moves reversely, sends a stop signal to the control module, and stops the driving motor 21 from working.

[0053] The design of the fastening rod 51 and the fastening portion 52 can have multiple implementation ways. For example, the fastening rod 51 can adopt different materials and shapes to adapt to different use requirements and environments; the arc-shaped guide surface 522 and the stop block 523 of the fastening portion 52 can also be optimized according to specific design requirements to improve the stability and reliability of fastening. Through these designs, it can effectively avoid the safety hazards caused by misoperation or unstable structure of the juicer during use.

[0054] Through the above design, the scheme of the present application can ensure the normal operation of the juicer while providing multiple safety protection, avoiding the risk of misstart and exposed knives, and improving the use safety and reliability of the juicer. Compared with the prior art, the scheme of the present application has significantly improved in the aspects of protective coverage range and reliability, and can better meet the high requirements of consumers for the safety of kitchen appliances.

[0055] Specifically, the fastening rod 51 comprises a first holding portion 511 arranged in an arc shape, two first rod bodies 512 arranged on both sides of the first holding portion 511, and two second rod bodies 513 arranged at the free ends of the two first rod bodies 512; the first rod body 512 and the second rod body 513 are perpendicular to each other, an included angle is arranged between the plane where the first holding portion 511 is located and the plane where the first rod body 512 is located, and the first clamping groove 521 is used for accommodating the first rod body 512.

[0056] The design of the fastening mechanism 5 plays a key role in the overall safety protection structure. By cooperating the fastening rod 51 with the fastening portion 52 of the upper cover body 3, it is ensured that the upper cover body 3 can be stably arranged on the juicing cutter 22, thereby avoiding the risk of exposing the cutter during juicing. The arc-shaped design of the first holding portion 511 not only improves the comfort of holding, but also enhances the convenience of operation. The perpendicular arrangement of the first rod body 512 and the second rod body 513 and the included angle between them and the first holding portion 511 enable the fastening rod 51 to smoothly rotate during operation and cooperate with the first clamping groove 521, ensuring the reliability and stability of the fastening mechanism 5.

[0057] The design of the first clamping groove 521 enables the first rod body 512 to be stably accommodated therein, ensuring that the fastening rod 51 does not deviate or loosen during operation. Through this structural design, not only the safety and reliability of the fastening mechanism 5 are improved, but also the operation steps are simplified, making it more convenient and fast for users to use the high-speed juicer.

[0058] Through this improvement, the high-speed juicer of the present application can effectively avoid safety hazards such as accidental start and cutter exposure during use, improve the safety and reliability of the product, and solve the problems of single protection measure and narrow coverage range in the prior art.

[0059] Specifically, the linkage control mechanism 4 further comprises a first bracket 44 arranged in the base 1, the first bracket 44 is provided with a first accommodating groove 441 for accommodating the micro switch 43, the first accommodating groove 441 is provided with an elastic reset member 442, and the moving rod 42 is arranged on the first bracket 44 through the elastic reset member 442.

[0060] This design aims to solve the safety hazard problem of the juicer in use in the prior art. By arranging the first bracket 44 in the base 1 and arranging the first accommodating groove 441 for accommodating the micro switch 43 on the first bracket 44, the stability of the micro switch 43 during operation of the juicer can be ensured. The arrangement of the elastic reset member 442 enables the moving rod 42 to automatically reset after being subjected to external force, further improving the safety and reliability of the juicer.

[0061] The first support 44 can be made of metal or high-strength plastic material to ensure its durability and stability during long-term use. The elastic return member 442 can be a spring, a rubber pad, or other materials with elastic properties, so that the appropriate material and structure can be selected according to actual needs. The design of the moving rod 42 needs to consider its cooperation with the elastic return member 442, so that the moving rod 42 can smoothly reciprocate.

[0062] In this way, the juicer can trigger the micro switch 43 through the elastic return member 442 when the upper cover body 3 is tightly matched with the base 1, so as to start the work of the juicer. When the upper cover body 3 is separated from the base 1, the moving rod 42 is reset under the action of the elastic return member 442, the micro switch 43 is disconnected, and the juicer stops working. Therefore, the safety and reliability of the juicer during operation are further improved.

[0063] This design not only solves the deficiency of the juicer in the prior art in the protection structure, but also avoids misoperation caused by external force through the setting of the elastic return member 442, thereby improving the use safety and user experience of the juicer.

[0064] Specifically, the base 1 is provided with a first through hole 10, and the first support 44 is provided with a second through hole 443 for cooperating with the elastic return member 442. The moving rod 42 includes a vertical rod 421 and a second guide column 422 arranged at one end of the vertical rod 421 away from the upper cover body 3. The free end of the vertical rod 421 extends into the first through hole 10 and cooperates with the first pressing block 41, and the free end of the second guide column 422 extends into the second through hole 443 and abuts against the elastic return member 442.

[0065] The technical scheme sets the first through hole 10 on the base 1 and the second through hole 443 for cooperating with the elastic return member 442 on the first support 44, so that the moving rod 42 can stably reciprocate. The moving rod 42 includes the vertical rod 421 and the second guide column 422. The free end of the vertical rod 421 extends into the first through hole 10 and cooperates with the first pressing block 41, and the free end of the second guide column 422 extends into the second through hole 443 and abuts against the elastic return member 442. Through this design, it can be ensured that the moving rod 42 can smoothly transmit motion when subjected to external force, and can be restored to the initial position through the elastic return member 442 after the external force is removed.

[0066] The vertical rod 421 and the second guide column 422 can have various implementations. For example, the vertical rod 421 can have a cylindrical or square column structure (in this embodiment, the vertical rod 421 has a cuboid structure, which is designed to optimize the internal space of the base 1), so as to adapt to different shapes of the first through hole 10 and the second through hole 443. At the same time, the elastic return member 442 can be a spring, a rubber pad or other elastic material, so as to ensure that the moving rod 42 can quickly return to the initial position after the external force is removed. In addition, the connection mode of the first pressing block 41 and the second guide column 422 can also be adjusted according to specific needs, such as threaded connection, buckle connection or welding.

[0067] Through the above technical solutions, the mobile rod 42, the first through hole 10, the second through hole 443 and the elastic return member 442 are introduced into the multiple safety protection structure of the juicer, so that the mobile rod 42 can stably and flexibly reciprocate, thereby achieving effective protection of the juicing knife 22. Compared with the prior art, the design of the present application not only improves the safety, but also simplifies the structure, facilitates production and maintenance.

[0068] Specifically, the vertical rod 421 is provided with a limiting plate 423 at one end away from the upper cover body 3, the limiting plate 423 is provided with a third through hole 424, the extending direction of the limiting plate 423 is perpendicular to the extending direction of the vertical rod 421, the second guide column 422 is arranged on the side of the limiting plate 423 away from the vertical rod 421, and the base 1 is further provided with a third guide column 101 for passing through the third through hole 424.

The displacement distance of the moving rod 42 in the vertical direction is limited by means of the stop portion 4211 and the limiting plate 423, so as to prevent the moving rod 42 from being separated from the base 1 and the upper cover body 3.

[0069] The vertical rod 421 is provided with a limiting plate 423 at one end away from the upper cover body 3, the limiting plate 423 is provided with a third through hole 424, the extending direction of the limiting plate 423 is perpendicular to the extending direction of the vertical rod 421, the second guide column 422 is arranged on the side of the limiting plate 423 away from the vertical rod 421, and the base 1 is further provided with a third guide column 101 for passing through the third through hole 424. The design of the limiting plate 423 can effectively control the movement range of the vertical rod 421, ensure that the vertical rod 421 does not move excessively or deviate during work, and thus ensure that the linkage between the micro switch 43 and the moving rod 42 is more stable and reliable.

[0070] The third through hole 424 of the limiting plate 423 can be used in cooperation with the third guide column 101 on the base 1. By passing through the third through hole 424 through the third guide column 101, the moving direction and range of the vertical rod 421 can be further limited, so that the movement of the moving rod 42 is more accurate. In this way, not only the triggering accuracy of the micro switch 43 can be improved, but also the stability and reliability of the entire safety protection structure can be enhanced.

[0071] Specifically, the design of the limiting plate 423 and the stop portion 4211 strictly limits the movement of the vertical rod 421, avoiding the situation that the vertical rod 421 moves excessively or deviates during work, so as to ensure that the linkage and cooperation of the micro switch 43 and the moving rod 42 are more stable and reliable. The third through hole 424 on the limiting plate 423 is used in cooperation with the third guide column 101 on the base 1. By passing through the third through hole 424 through the third guide column 101, the moving direction and range of the vertical rod 421 can be further limited, so that the movement of the moving rod 42 is more accurate. In this way, not only the triggering accuracy of the micro switch 43 can be improved, but also the stability and reliability of the entire safety protection structure can be enhanced.

[0072] Specifically, the outer wall of the third protective cover 13 is concavely provided with an avoiding groove 131, and the moving rod 42 reciprocally moves in the avoiding groove 131. This kind of structural design can optimize the internal installation space of the base 1, and can also ensure that the moving rod 42 does not deviate during movement.

[0073] Specifically, the end of the moving rod 42 away from the upper cover body 3 is provided with a first guide plane 425, one side of the moving rod 42 is provided with a second guide plane 426 connected with the first guide plane 425, and an included angle is arranged between the first guide plane 425 and the second guide plane 426; the forward movement of the moving rod 42 makes the first guide plane 425 and the second guide plane 426 successively abut against the contact of the micro switch 43 to make the micro switch 43 provide an opening signal to the control module, and the reverse movement of the moving rod 42 makes the second guide plane 426 and the first guide plane 425 successively leave the contact of the micro switch 43 to make the micro switch 43 provide a stop signal to the control module.

[0074] In this embodiment, the first guide plane 425 and the second guide plane 426 are arranged on the second guide column 422, which is substantially cylindrical. When the moving rod 42 moves forward, the first guide plane 425 and the second guide plane 426 of the second guide column 422 successively contact the contact points of the micro switch 43, so that the micro switch 43 provides an opening signal to the control module; when the moving rod 42 moves reversely, the second guide plane 426 and the first guide plane 425 successively leave the contact points of the micro switch 43, so that the micro switch 43 provides a stop signal to the control module. Thus, it is ensured that the juicer will not start when the upper cover body 3 of the juicer is not completely fastened, thereby improving the safety during use; at the same time, the arrangement of the first guide plane 425 and the second guide plane 426 makes the movement of the second guide column 422 more smooth and fast.

[0075] Specifically, the base 1 includes a first protective cover 11, a second protective cover 12 and a third protective cover 13 arranged in the first protective cover 11, the first protective cover 11 is located at the bottom of the first protective cover 11, and the third protective cover 13 is in communication with the second protective cover 12 and located above the second protective cover 12. The driving motor 21 is arranged in the second protective cover 12, and the juicing knife 22 is arranged in the third protective cover 13, and the output shaft 211 of the driving motor 21 penetrates through the bottom wall of the third protective cover 13 and is connected with the juicing knife 22.

[0076] The base 1 of the present application is designed with multiple protective cover structures, the first protective cover 11, the second protective cover 12 and the third protective cover 13 are arranged in sequence to form multiple layers of protection. The driving motor 21 is arranged in the second protective cover 12, and the juicing knife 22 is arranged in the third protective cover 13, and the output shaft 211 of the driving motor 21 penetrates through the bottom wall of the third protective cover 13 and is connected with the juicing knife 22. This design effectively isolates the driving motor 21 and the juicing knife 22, preventing accidental contact and injury that may occur during juicing.

[0077] Specifically, the first protective cover 11 is located at the bottom of the base 1 and mainly plays a supporting and protecting role. The second protective cover 12 completely wraps the driving motor 21, preventing external objects from contacting the driving motor 21 and avoiding possible electric shock and mechanical injury. The third protective cover 13 completely covers the juicing knife 22, so that only the blade part of the juicing knife 22 is exposed through the small hole when the juicing knife 22 is working, further improving the use safety.

[0078] Therefore, through the design of the multiple protective covers, the safety of the juicer is improved, misoperation and accidental injury are prevented, and the operation of the driving motor 21 and the juicing knife 22 is more stable and reliable. Compared with the prior art, the present application optimizes and improves the protection of the juicing knife 22 area, the safety linkage of the operation trigger, and the automatic cutting-off in the abnormal state, and solves the problems of narrow protection coverage and limited reliability in the prior art.

[0079] Specifically, the multiple safety protection structure of the juicer further comprises a knife guard shell 6 reciprocally arranged on the base 1, the knife guard shell 6 covers the outside of the juicing knife 22, the top of the knife guard shell 6 has an avoiding hole 60 through which the blade of the juicing knife 22 passes, the upper cover body 3 is provided with a feeding cylinder 7 coaxially matched with the juicing knife 22, and the feeding cylinder 7 is reciprocally arranged with a pressing piece 71 inside, the pressing piece 71 has an inner pressing column 711 and an outer pressing shell 712 located outside the inner pressing column 711, and the distance between the bottom of the outer pressing shell 712 and the knife guard shell 6 is less than the distance between the bottom of the inner pressing column 711 and the knife guard shell 6. After the external fruit is placed in the feeding cylinder 7, the pressing piece 71 is pressed downward under the action of external force, so that the outer pressing shell 712 abuts against the knife guard shell 6 to move downward to expose the juicing knife 22, and the inner pressing column 711 synchronously presses the fruit to the juicing knife 22 for juicing operation.

[0080] The present application protects the juicing knife 22 by arranging the knife guard shell 6, avoiding potential safety risks caused by exposed knives. The top of the knife guard shell 6 is provided with an avoiding hole 60, so that the blade of the juicing knife 22 can pass through the avoiding hole 60 to perform juicing operation. The upper cover body 3 is provided with a feeding cylinder 7, and the feeding cylinder 7 is provided with a pressing piece 71 inside, the pressing piece 71 includes an inner pressing column 711 and an outer pressing shell 712, and the distance between the bottom of the outer pressing shell 712 and the knife guard shell 6 is less than the distance between the bottom of the inner pressing column 711 and the knife guard shell 6. The outer pressing shell 712 abuts against the knife guard shell 6 to move downward to expose the juicing knife 22, and the inner pressing column 711 presses the fruit to the juicing knife 22 for juicing operation.
