Description

Technical Field

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

[0002] Existing food processors, such as blenders and soy milk makers, typically consist of a main unit with a built-in motor and a detachable cup body located on top of the main unit. The cup body contains a grinding device, which the motor drives to rotate. When using the food processor, the user places the ingredients into the cup body, and the grinding device rotates at high speed under the motor's power to process the ingredients. In earlier versions of food processors, the motor would start processing the ingredients even if the lid was not closed properly or not fully closed. This could cause food to splatter during processing, and the user could easily put their hands inside the cup, posing a significant safety risk.

[0003] To address the aforementioned issues, the applicant's earlier patent application CN220124565U discloses a reliable food processing machine. This machine incorporates a microswitch within the handle to control the on / off state of the motor. The microswitch is only triggered when the lid is fully closed, ensuring safe and stable food processing. However, the microswitch is connected to the motor control board via a low-voltage circuit. After activation, the microswitch transmits a low-voltage signal to the control board, which then controls the motor. This results in a delay in the motor stopping when the microswitch is deactivated, and there is a risk of failure after prolonged use. With the release of the new national standard (GB / T4706.19-2024 Safety of household and similar electrical appliances, Part 19: Particular requirements for liquid heaters), the motor must stop synchronously when the lid is opened. This necessitates that the microswitch be directly connected to the motor via a high-voltage wire, such as a neutral or live wire, so that the motor stops synchronously the instant the microswitch is deactivated. Faced with the above problems, those skilled in the art would readily think of improving the existing micro switch by directly connecting it to the motor via high voltage. The existing method of connecting the micro switch to the motor via low voltage has a smaller voltage, so if moisture or other substances enter during use, it will have little impact on the micro switch and can still maintain normal operation, thus having a lower waterproof requirement. However, after changing the low voltage to high voltage, the micro switch is directly connected to the mains power, which has a higher voltage. Therefore, the waterproof requirement is higher. Waterproof micro switches have a complex structure and a large size, occupying a lot of space inside the handle. Installing them inside the handle would make the handle too large, greatly reducing the user's grip and seriously affecting the consumer's user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a food processing machine with optimized structure, in order to solve the problem of how to avoid the problem of excessively large handle size caused by the use of waterproof microswitches, under the premise that existing food processing machines use microswitches electrically connected to the motor to ensure that the motor can only be started when the cup lid is closed.

[0005] To achieve the above objectives, this utility model provides a food processing machine with optimized structure, including a main unit and a detachable cup body located above the main unit. The cup body is equipped with a crushing device. The cup body includes a crushing cup, a handle fixed to the side wall of the crushing cup, a cup lid covering the crushing cup, and a motor fixed below the crushing cup. The main unit includes a support part supported below the cup body and a baffle part extending upward from the outer periphery of the support part and surrounding the outer side of the cup body. A micro switch is provided inside the baffle part, and the micro switch is connected in series with the motor through a neutral wire. A trigger rod extending vertically is provided between the handle and the side wall of the crushing cup. After the cup lid is closed, it presses against the trigger rod and moves downward to trigger the micro switch.

[0006] This application designs the main unit as including a support portion supported beneath the cup body and a retaining portion extending upwards from the outer periphery of the support portion and surrounding the outside of the cup body. This allows the user to not only receive axial support from the support portion when placing the cup on the main unit, but also achieve circumferential and radial limitation of the cup body through the retaining portion, thereby improving the stability and positioning accuracy of the cup body's fit with the main unit. Furthermore, a microswitch is installed within the retaining portion, enabling the retaining portion to both limit the cup body's movement and securely mount the microswitch. This avoids the problem of an excessively large handle caused by placing the microswitch inside the handle, contributing to the miniaturization of the handle and the entire cup body, reducing the overall weight of the cup, and improving the user's grip and ease of use. In addition, the microswitch is connected in series with the motor via a neutral wire, allowing for rapid power cut-off when the cup lid is opened, ensuring the crushing device stops rotating immediately, meeting the requirements of the new national standard. Furthermore, a vertically extending trigger rod is provided between the handle and the side wall of the grinding cup. After the cup lid is closed, it presses against the trigger rod and moves downward to trigger the micro switch. This allows the trigger rod to move rapidly when the cup lid is closed and opened, thereby accurately triggering or releasing the micro switch. This ensures that the micro switch's action response is rapid and stable. Compared to designs that place the micro switch inside the handle, the trigger rod can increase the distance between the micro switch and the cup lid, thus preventing moisture generated during food processing from contacting the micro switch. This effectively reduces the risk of moisture damage and improves the overall waterproof performance, thereby greatly enhancing the waterproof performance of the micro switch. This effectively avoids short circuit problems caused by moisture intrusion and further improves the safety and stability of the food processor in humid environments.

[0007] In a preferred embodiment of a structurally optimized food processing machine, the cup body further includes a cup holder fixed to the outer side of the bottom of the cup body and a cup body outer shell fixed to the outer side of the bottom of the cup holder, and the bottom of the trigger linkage extends downward from the outer side of the cup holder into the space between the cup holder and the cup body outer shell.

[0008] By designing the bottom of the trigger linkage to extend downwards from the outside of the cup holder into the space between the cup holder and the outer shell of the cup, the entire trigger linkage is located within the handle and the outer shell of the cup, thus achieving concealment of the trigger linkage. On the one hand, the interaction between the handle and the pulverizing cup, as well as the interaction between the outer shell of the cup and the cup holder, guides the trigger linkage, ensuring its stability during reciprocating movement and preventing deviation or jamming during movement. On the other hand, it prevents the trigger linkage from being exposed to the outside environment, thus avoiding easy collision with external structures and damage to it, thereby achieving a protective function for the trigger linkage.

[0009] In a preferred embodiment of a structurally optimized food processor, the trigger link includes a first vertical segment located between the handle and the side wall of the crushing cup and extending vertically downward, a first bent segment that bends laterally outward and extends downward to the outside of the cup base, and a second bent segment that bends laterally inward and extends downward to the area between the cup base and the outer shell of the cup body.

[0010] By setting the trigger link to include a first vertical section extending vertically downward between the handle and the side wall of the crushing cup, a first bent section bending horizontally outward and extending downward to the outside of the cup base, and a second bent section bending horizontally inward and extending downward to the area between the cup base and the outer shell of the cup, the trigger link has a staggered three-dimensional structure, which better adapts to the spatial layout between the handle and the cup body, further improves the structural compactness and assembly stability, and helps to further realize the miniaturization of the cup body.

[0011] In a preferred embodiment of a structurally optimized food processor, the cup holder includes a fixing part fixed to the outside of the grinding cup and a support part located below the grinding cup with a reduced inner diameter. The trigger link has a limiting section that bends laterally inward and is located below the support part, and a trigger section that extends vertically downward from the limiting section into the outer shell of the cup body.

[0012] By configuring the cup holder to include a fixing part fixed to the outside of the grinding cup and a support part located below the grinding cup with a reduced inner diameter, the cup holder can not only achieve a stable connection with the grinding cup through the fixing part, but also effectively support the bottom of the grinding cup through the support part, further improving the stability and robustness of the grinding cup during operation. Furthermore, the trigger link has a limiting section that bends laterally inward and is located below the support part, and a trigger section that extends vertically downward from the limiting section into the outer shell of the cup body. This allows the trigger link to be limited by the axial stop of the limiting section and the support part, ensuring that the trigger link will not deviate from its predetermined track when moving up and down, guaranteeing the stability of the trigger link's position, and enabling the trigger section to trigger the micro switch.

[0013] In a preferred embodiment of a structurally optimized food processing machine, a stop structure is provided inside the cup holder below the limiting section, and a return spring is provided between the stop structure and the limiting section.

[0014] By providing a stop structure located below the limiting section within the cup holder, and a return spring between the stop structure and the limiting section, the trigger linkage moves downward when the cup lid is closed on the grinding cup by pressing down on the trigger linkage. During this movement, the return spring is compressed and deformed, storing elastic kinetic energy. When the cup lid separates from the grinding cup, the return spring releases the elastic kinetic energy and pushes the trigger linkage upward to reset, thereby causing the trigger section to disengage from the micro switch, thus realizing the safety power-off protection function of the food processor.

[0015] In a preferred embodiment of a structurally optimized food processing machine, a first magnet is provided at the bottom of the trigger linkage, and a micro switch includes a stationary contact and a spring with a moving contact. A second magnet that is magnetically repelled by the first magnet is provided on the spring. After the cup lid is closed, it presses against the trigger linkage and moves downward, aligning the first magnet with the second magnet to trigger the micro switch.

[0016] By providing a first magnet at the bottom of the trigger linkage, the micro switch includes a stationary contact and a spring with a moving contact. A second magnet, which is magnetically repelled by the first magnet, is placed on the spring. As the trigger linkage moves downward, the first magnet aligns laterally with the second magnet, and the magnetic repulsion causes the spring to deform, making the moving contact contact the stationary contact. This conducts the circuit and starts the food processor. This achieves triggering without contact, eliminating the need for through holes in the cup body and enclosure for the trigger linkage to pass through. This helps improve the overall sealing of the food processor and further enhances the waterproof protection of the micro switch.

[0017] In a preferred embodiment of a structurally optimized food processing machine, the bottom end of the trigger linkage is provided with a mounting groove with an opening facing the micro switch. The first magnet is fixed in the mounting groove, and after the cup lid is closed and presses against the trigger linkage to move downward, the first magnet and the second magnet are laterally aligned.

[0018] By providing a mounting groove with an opening facing the micro switch at the bottom of the trigger linkage, the first magnet is fixed in the mounting groove, achieving stable installation of the first magnet at the bottom of the trigger linkage. This ensures that the first magnet can accurately form magnetic alignment with the second magnet on the spring when it moves downward. At the same time, the limiting effect of the mounting groove prevents the first magnet from shifting or loosening, thereby ensuring the reliability of magnetic triggering and further improving the sensitivity and safety of the overall control system of the food processing machine.

[0019] In a preferred embodiment of a structurally optimized food processing machine, the cup body further includes a cup holder fixed to the outer side of the bottom of the cup body and a cup body shell fixed to the outer side of the bottom of the cup holder. The side wall of the cup body shell is provided with a first step portion with the first step surface facing downward, and the inner side wall of the enclosure portion is provided with a second step portion with the second step surface facing upward. The second step surface is supported below the first step surface. The micro switch is provided with a trigger button, and the bottom end of the trigger linkage can pass through the first step surface and the second step surface and press against the trigger button.

[0020] By providing a first step with its first step facing downwards on the side wall of the outer shell of the cup, and a second step with its second step facing upwards on the inner side wall of the enclosure, with the second step supported below the first step, the cup can achieve axial support not only through the support portion but also through the cooperation between the second and first steps, further enhancing the stability of the cup and the main unit. Simultaneously, the microswitch has a trigger button. The bottom end of the trigger rod can pass through both the first and second step surfaces and press against the trigger button. This allows the trigger rod to pass through the first and second step surfaces sequentially during downward movement and achieve precise alignment with the trigger button, effectively triggering the microswitch and further ensuring stable startup of the food processor after the cup lid is fully closed.

[0021] In a preferred embodiment of a structurally optimized food processing machine, the micro switch includes a housing, a switch body disposed within the housing, and a trigger button exposed to the outside. After the cup lid is closed, it presses against the trigger button to trigger the micro switch. The housing is fixed with a waterproof flexible component surrounding the outside of the trigger button. The waterproof flexible component is sleeved on the outside of the trigger button and can move back and forth with the trigger button.

[0022] By fixing a waterproof flexible component around the trigger button to the housing, and having the component sleeve the trigger button and reciprocate with it, a sealed connection is formed between the housing and the trigger button through the waterproof flexible component. This effectively prevents liquid from seeping into the microswitch, thereby improving the overall waterproof performance and service life. Simultaneously, the waterproof flexible component's reciprocating movement ensures that the trigger button maintains a sealed fit with the housing during this process, guaranteeing the microswitch's waterproof performance.

[0023] In a preferred embodiment of a structurally optimized food processor, a seal is provided between the handle and the side wall of the grinding cup, and the seal has a clearance opening through which the trigger linkage passes.

[0024] By providing a seal between the handle and the side wall of the grinding cup, and by providing a clearance opening for the trigger linkage to pass through, the seal effectively blocks water stains flowing downwards from the top of the handle during cleaning or use of the food processor, preventing the water stains from continuing to flow downwards and further improving its waterproof performance.

Detailed Implementation

[0035] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0036] 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.

[0037] like Figures 1 to 7 As shown, this utility model provides a food processing machine with optimized structure, including a main unit 4 and a detachable cup body located above the main unit 4. The cup body is equipped with a crushing device. The cup body includes a crushing cup 3, a handle 2 fixed to the side wall of the crushing cup 3, a cup lid 1 covering the crushing cup 3, and a motor fixed below the crushing cup 3. The main unit 4 includes a support part 41 supported below the cup body and a baffle part 42 extending upward from the outer periphery of the support part 41 and surrounding the outer side of the cup body. A micro switch 8 is provided inside the baffle part 42, and the micro switch 8 is connected in series with the motor through a neutral wire. A trigger rod 5 extending vertically is provided between the handle 2 and the side wall of the crushing cup 3. After the cup lid 1 is closed, it presses against the trigger rod 5 and moves downward to trigger the micro switch 8.

[0038] This application configures the main unit 4 as including a support part 41 supported below the cup body and a retaining part 42 extending upward from the outer periphery of the support part 41 and surrounding the outside of the cup body. This allows the user to place the cup body on the main unit 4, achieving axial support through the support part 41 and circumferential and radial limiting of the cup body through the retaining part 42, thereby improving the stability and positioning accuracy of the cup body's fit with the main unit 4. Furthermore, a micro switch 8 is installed within the retaining part 42, allowing the retaining part 42 to both limit the cup body's position and securely install the micro switch 8. This avoids the problem of placing the micro switch 8 inside the handle 2, which would result in an excessively large handle 2. This contributes to the miniaturization of the handle 2 and the entire cup body, reducing the overall weight of the cup body and improving the user's grip and ease of use. In addition, the micro switch 8 is connected in series with the motor via a neutral wire, enabling the motor power to be quickly cut off when the cup lid 1 is opened, thus cutting off high-voltage power and ensuring the crushing device stops rotating immediately, meeting the requirements of the new national standard. Furthermore, a trigger rod 5 extending vertically is provided between the handle 2 and the side wall of the grinding cup 3. After the cup lid 1 is closed, it presses against the trigger rod 5 and moves downward to trigger the micro switch 8. This allows the cup lid 1 to drive the trigger rod 5 to move quickly when closing and opening, thereby accurately triggering or releasing the micro switch 8. This ensures that the micro switch 8 responds quickly and stably. Compared to the solution of placing the micro switch 8 inside the handle 2, the trigger rod 5 can increase the distance between the micro switch 8 and the cup lid 1, so that the moisture generated during food processing cannot come into contact with the micro switch 8, effectively reducing the risk of moisture and improving the overall waterproof performance. This greatly enhances the waterproof performance of the micro switch 8, effectively avoiding short circuit problems caused by moisture intrusion, and further improving the safety and stability of the food processor in humid environments.

[0039] As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the cup body also includes a cup holder 6 fixed to the outer side of the bottom of the cup body and a cup body shell 7 fixed to the outer side of the bottom of the cup holder 6. The bottom of the trigger linkage 5 extends downward from the outer side of the cup holder 6 into the space between the cup holder 6 and the cup body shell 7.

[0040] By setting the bottom of the trigger link 5 to extend downward from the outside of the cup holder 6 into the space between the cup holder 6 and the outer shell 7, the entire trigger link 5 is located inside the handle 2 and the outer shell 7, thus achieving the concealment of the trigger link 5. On the one hand, the cooperation between the handle 2 and the crushing cup 3, and the cooperation between the outer shell 7 and the cup holder 6, can guide the trigger link 5, ensuring the stability of the trigger link 5 during its up-and-down reciprocating movement and preventing deviation or jamming during movement. On the other hand, it prevents the trigger link 5 from being exposed to the outside world, which could easily lead to collisions with external structures and damage, thus achieving the protection of the trigger link 5.

[0041] Furthermore, such as Figure 4 As shown, the trigger link 5 includes a first vertical section 52 located between the handle 2 and the side wall of the crushing cup 3 and extending vertically downward, a first bent section 53 that bends laterally outward and extends downward to the outside of the cup base 6, and a second bent section 54 that bends laterally inward and extends downward to the area between the cup base 6 and the outer shell of the cup body 7.

[0042] By setting the trigger link 5 to include a first vertical section 52 located between the handle 2 and the side wall of the crushing cup 3 and extending vertically downward, a first bent section 53 that bends horizontally outward and extends downward to the outside of the cup base 6, and a second bent section 54 that bends horizontally inward and extends downward to the area between the cup base 6 and the outer shell of the cup body 7, the trigger link 5 has a staggered three-dimensional structure, which better adapts to the spatial layout between the handle 2 and the cup body, further improves the structural compactness and assembly stability, and helps to further realize the miniaturization of the cup body.

[0043] As a preferred embodiment of this implementation, such as Figure 2 , Figure 3 , Figure 4 As shown, the cup holder 6 includes a fixing part fixed to the outside of the crushing cup 3 and a support part located below the crushing cup 3 with a reduced inner diameter. The trigger link 5 is provided with a limiting section 55 that is bent inward laterally and located below the support part, and a trigger section that extends vertically downward from the limiting section 55 into the outer shell of the cup body 7.

[0044] By configuring the cup holder 6 to include a fixing part fixed to the outside of the crushing cup 3 and a support part located below the crushing cup 3 with a reduced inner diameter, the cup holder 6 can not only achieve a stable connection with the crushing cup 3 through the fixing part, but also effectively support the bottom of the crushing cup 3 through the support part, further improving the stability and firmness of the crushing cup 3 during operation. Furthermore, the trigger link 5 has a limiting section 55 that bends laterally inward and is located below the support part, and a trigger section that extends vertically downward from the limiting section 55 into the outer shell 7 of the cup body. This allows the trigger link 5 to be limited by the axial stop of the support part through the limiting section 55, ensuring that the trigger link 5 will not deviate from its predetermined track when moving up and down, guaranteeing the stability of the trigger link 5's position, and enabling the trigger section to trigger the micro switch 8.

[0045] Furthermore, such as Figure 4 As shown, the cup holder 6 has a stop structure located below the limiting section 55, and a return spring 10 is provided between the stop structure and the limiting section 55.

[0046] By providing a stop structure located below the limiting section 55 within the cup holder 6, and a return spring 10 between the stop structure and the limiting section 55, when the cup lid 1 is closed on the crushing cup 3, the trigger link 5 is pushed downward by the downward action of the trigger link 5. During the movement, the return spring 10 is compressed and deformed and stores elastic kinetic energy. When the cup lid 1 is separated from the crushing cup 3, the return spring 10 releases the elastic kinetic energy and pushes the trigger link 5 upward to reset, thereby causing the trigger section to disengage from the micro switch 8, realizing the safety power-off protection function of the food processor.

[0047] It should be noted that this application does not specifically limit the structure and triggering method of the micro switch 8, which can be any of the following embodiments:

[0048] Example 1: As Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, in this embodiment, the trigger link 5 is provided with a first magnet 9 at its bottom end, and the micro switch 8 includes a stationary contact and a spring 81 with a moving contact. A second magnet 82 that is magnetically repelled by the first magnet 9 is provided on the spring 81. After the cup lid 1 is closed, it presses the trigger link 5 to move downward and aligns the first magnet 9 with the second magnet 82 to trigger the micro switch 8.

[0049] By providing a first magnet 9 at the bottom of the trigger link 5, the micro switch 8 includes a stationary contact and a spring 81 with a moving contact. A second magnet 82, which is magnetically repelled by the first magnet 9, is provided on the spring 81. As the trigger link 5 moves downward, the first magnet 9 is laterally aligned with the second magnet 82, and the magnetic repulsion causes the spring 81 to deform, making the moving contact contact the stationary contact, thereby conducting the circuit and starting the working state of the food processor. This achieves triggering without contact, eliminating the need for through holes in the cup body and the enclosure 42 for the trigger link 5 to pass through. This helps to improve the sealing of the overall structure of the food processor and further enhances the waterproof protection of the micro switch 8.

[0050] Furthermore, such as Figure 3 As shown, the bottom end of the trigger linkage 5 is provided with a mounting groove 51 with an opening facing the micro switch 8. The first magnet 9 is fixed in the mounting groove 51. After the cup lid 1 is closed, it presses against the trigger linkage 5 and moves downward, and the first magnet 9 and the second magnet 82 are laterally aligned.

[0051] By providing a mounting groove 51 with an opening facing the micro switch 8 at the bottom of the trigger link 5, the first magnet 9 is fixed in the mounting groove 51, achieving stable installation of the first magnet 9 at the bottom of the trigger link 5. This ensures that it can accurately form magnetic alignment with the second magnet 82 on the spring 81 when it moves downward. At the same time, the limiting effect of the mounting groove 51 prevents the first magnet 9 from shifting or loosening, thereby ensuring the reliability of magnetic triggering and further improving the sensitivity and safety of the overall control system of the food processing machine.

[0052] Example 2: In this example, the cup body also includes a cup holder 6 fixed to the outer side of the bottom of the cup body and a cup body shell 7 fixed to the outer side of the bottom of the cup holder 6. The side wall of the cup body shell 7 is provided with a first step portion with the first step surface facing downward, and the inner side wall of the enclosure portion 42 is provided with a second step portion with the second step surface facing upward. The second step surface is supported below the first step surface. The micro switch 8 is provided with a trigger button, and the bottom end of the trigger linkage 5 can pass through the first step surface and the second step surface and press against the trigger button.

[0053] By providing a first step with its first step facing downwards on the side wall of the outer shell 7 of the cup body, and a second step with its second step facing upwards on the inner side wall of the enclosure 42, with the second step supported below the first step, the cup body can achieve axial support not only through the support part 41, but also through the cooperation between the second step and the first step, further enhancing the stability of the cup body and the main unit 4. Simultaneously, the micro switch 8 is equipped with a trigger button. The bottom end of the trigger rod 5 can pass through the first and second step surfaces and press against the trigger button, allowing the trigger rod 5 to pass through the first and second step surfaces sequentially during downward movement and achieve precise alignment with the trigger button, thereby effectively triggering the micro switch 8 and further ensuring stable startup of the food processor after the cup lid 1 is fully closed.

[0054] Furthermore, the micro switch 8 includes a housing, a switch body disposed within the housing, and a trigger button exposed to the outside. After the cup lid 1 is closed in place, it presses against the trigger button to trigger the micro switch 8. The housing is fixed with a waterproof flexible component surrounding the outside of the trigger button. The waterproof flexible component is sleeved on the outside of the trigger button and can move back and forth with the trigger button.

[0055] By fixing a waterproof flexible component around the trigger button to the housing, and having the component sleeved around the trigger button and capable of reciprocating with it, a sealed connection is formed between the housing and the trigger button through the waterproof flexible component. This effectively prevents liquid from seeping into the microswitch 8, thereby improving the overall waterproof performance and service life. Simultaneously, the waterproof flexible component's reciprocating movement ensures that the trigger button maintains a sealed fit with the housing during reciprocating motion, guaranteeing the waterproof performance of the microswitch 8.

[0056] In a preferred embodiment of this application, a sealing element is provided between the handle 2 and the side wall of the crushing cup 3, and the sealing element is provided with a clearance opening for the trigger linkage 5 to pass through.

[0057] By providing a seal between the handle 2 and the side wall of the crushing cup 3, and by providing a clearance opening for the trigger linkage 5 to pass through, the seal effectively blocks water stains flowing downwards from the top of the handle 2 during cleaning or use of the food processor, preventing the water stains from continuing to flow downwards and further improving the waterproof performance.

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.
