Description

Technical Field

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

[0002] Existing food processors typically include a motor and a cup body located above the motor and containing a shredder. When using the food processor, the user places the ingredients into the cup body, and the shredder rotates at high speed driven by the motor to process the ingredients. With the increasing demand for portable food processors when users are traveling, most manufacturers are producing miniaturized, portable models. For example, Chinese patent CN220212741U discloses a new type of food processor cup. This cup-shaped food processor has a lid on top, which can be fastened to the cup body to seal the grinding chamber. For added convenience, the lid includes a spout and a movable plate that can close the spout. The movable plate is pivotally connected to the lid. When the user needs to drink or process food, the movable plate can be moved to open the spout, allowing direct drinking without removing the lid from the cup body, making operation more convenient. During food processing, opening the spout allows gases generated inside the cup to escape, maintaining pressure balance and preventing the lid from being lifted due to excessive pressure. Furthermore, when carrying the food processor, the movable plate can be flipped to close the spout, ensuring a sealed container.

[0003] Furthermore, the movable plate is equipped with a magnet, and the cup body has a magnetic induction switch that can be triggered by the magnet to open or close. The magnetic induction switch is electrically connected to the control circuit board. When the movable plate is open, it approaches the magnetic induction switch, and the magnet causes the magnetic induction switch to close, powering the blender. When the movable plate is closed on the spout, the magnet moves away from the magnetic induction switch, causing the magnetic induction switch to open, powering the blender. However, in this model, the cup body and motor are fixed together in the same housing, making deep cleaning of the cup impossible. In particular, due to the depth of the cup, users cannot reach the bottom to clean the area below the pulverizing blade, resulting in a significant accumulation of dirt over time, severely impacting the user experience. If the cup body and motor were separated, a through hole would need to be provided at the bottom of the cup body for the push rod driving the lid to pass through, and a similar through hole would need to be provided at the top of the main unit for the push rod to pass through to trigger the micro switch. This would significantly reduce the sealing of the cup body and the main unit, allowing cleaning water to easily enter the main unit through the through holes, causing electrical components to become damp, malfunction, or even be damaged, severely affecting the consumer experience. Utility Model Content

[0004] The purpose of this utility model is to provide a portable food processor to solve the problem of how to avoid the decrease in the sealing of the main unit caused by setting through holes for the top rod to pass through in the main unit and the cup body to ensure the triggering of the micro switch, under the premise that the cup body and the main unit are detachable to achieve deep cleaning of the cup body.

[0005] To achieve the above objectives, this utility model provides a portable food processor, comprising a main unit with a motor and a detachable grinding cup located above the main unit. The grinding cup includes a cup body with a grinding chamber and a cup lid detachably covering the cup body. The main unit includes a housing for the motor. The cup lid includes a lower cover and an upper cover movably connected above the lower cover. The lower cover has an exhaust port communicating with the grinding chamber and the outside. The upper cover can move relative to the lower cover to open or close the exhaust port. The grinding cup is vertically through-hole shaped, and its bottom end is detachably fixed to the top of the main unit. The main unit has a magnetic control switch electrically connected to the motor. The grinding cup has an axially arranged and movable trigger rod. The bottom end of the trigger rod has a first magnet. When the upper cover opens the exhaust port, the upper cover can push the trigger rod downward and drive the first magnet downward to trigger the magnetic control switch.

[0006] This application designs the cup lid as including a lower lid and an upper lid movably connected above the lower lid. The lower lid has an exhaust port connecting the grinding chamber to the outside. The upper lid can move relative to the lower lid to open or close the exhaust port, allowing users to flexibly control the opening and closing of the exhaust port by rotating the upper lid to meet the exhaust needs of different working states. For example, when processing food ingredients with the food processor, the user can rotate the upper lid to open the exhaust port to release the gas generated during the grinding and heating processes, preventing excessive pressure in the grinding chamber from causing the cup lid to pop up. At the same time, when carrying or storing food, the user can rotate the upper lid to close the exhaust port to prevent food from spilling, ensuring ease of use and safety, and improving the user experience. Furthermore, the grinding cup is vertically continuous, and the bottom is detachably fixed to the top of the main unit, allowing the user to detach the cup from the main unit after using the food processor for deep cleaning of both the cup and the main unit. Users can directly clean the grinding device, making cleaning more convenient and faster, and improving the user experience.

[0007] In addition, the main unit is equipped with a magnetic control switch electrically connected to the motor, and the grinding cup is equipped with an axially arranged and movable trigger rod. The bottom end of the trigger rod is equipped with a first magnet. When the vent is opened, the top cover can push the trigger rod downward and move the first magnet downward to trigger the magnetic control switch. This ensures that the user can only push the trigger rod and move the first magnet to trigger the magnetic control switch when the vent is open and the cup cover is fastened to the cup body, thus starting the motor to process the food. This ensures that gas can be smoothly discharged through the vent during food processing, guaranteeing the stability of food processing and preventing excessive pressure in the grinding chamber caused by processing food with the vent closed. It also prevents accidental motor start-up and improves operational safety. Compared to existing designs that use a push rod to press down on a microswitch to start the motor, this application achieves a remote triggering function through the cooperation of a magnetic switch and a trigger linkage. This eliminates the need for openings at the bottom of the cup and the top of the main unit to allow the push rod to pass through, thus ensuring the integrity of the cup and main unit structure and guaranteeing their airtightness. This prevents water from entering the main unit through openings during machine cleaning, which could cause electrical components to become damp, malfunction, or even be damaged. This provides waterproof protection for the entire machine, helps extend its service life, and ensures the stability of the food processing machine's operation.

[0008] In a preferred embodiment of a portable food processor, the outer casing includes an outer casing body with an open top and a heating plate fixed at the open top of the outer casing body. The heating plate has a pulverizing blade connected to the motor shaft of a motor in the middle, and a magnetic control switch is located between the outer casing and the heating plate.

[0009] By directly fixing the heating plate to the open part of the outer casing, the heating plate serves as the top wall of the main unit and the bottom wall of the grinding chamber, greatly simplifying the overall structure and contributing to a more compact design, especially in terms of axial dimension reduction. Simultaneously, the magnetic switch is located between the outer casing and the heating plate, maximizing the use of internal space and radial space, further enhancing the compactness of the food processor and making it more convenient for users to carry.

[0010] In a preferred embodiment of a portable food processor, the magnetic switch includes a switch body with contacts and a spring extending outward from the body. The spring has a second magnet, and the magnetic poles of the first magnet and the second magnet are the same on the side that are close to each other.

[0011] By configuring the magnetic switch as a switch body with contacts and a spring extending outward from the body, with a second magnet on the spring, and the magnetic poles of the first and second magnets being the same on their adjacent sides, when the first magnet moves downward with the trigger rod, the first magnet generates a repulsive force on the second magnet, pushing the second magnet toward the contacts until the contacts make contact with the spring, thereby closing the circuit and starting the motor. This ensures accurate operation and achieves remote triggering of the magnetic switch. At the same time, when the trigger rod moves upward, the repulsive force of the first magnet on the second magnet weakens, and the second magnet resets under the elastic force of the spring, separating the contacts from the spring, disconnecting the circuit, and stopping the motor. This further improves the convenience and safety of operation.

[0012] In a preferred embodiment of a portable food processor, the vertical projection of the first magnet falls at least partially into the second magnet.

[0013] By setting the projection of the first magnet in the vertical direction to at least partially fall into the second magnet, the first magnet and the second magnet are at least partially overlapped in the vertical direction. This allows the first magnet to more effectively generate a repulsive force on the second magnet when it moves downward, ensuring that the contact piece and the spring piece make rapid contact, the circuit closes precisely, and the motor starts stably. At the same time, it avoids starting delays or failures caused by magnet misalignment, further improving the reliability of operation and user experience.

[0014] In a preferred embodiment of a portable food processor, the housing includes a housing body and a mounting base that is reduced in diameter and convex upward relative to the inner diameter of the housing body. The bottom end of the mounting base is connected to the top end of the housing body via a stepped surface. A first magnet is located directly above the stepped surface, and a second magnet is located directly below the stepped surface.

[0015] By positioning the first magnet directly above the step surface and the second magnet directly below it, ensuring their vertical alignment, the magnetic force's effective range is maximized. This improves the response speed and stability of the magnetic switch, further optimizing the precise control of motor start and stop, and enhancing the overall smoothness and durability of the machine. Simultaneously, the bottom of the cup abuts against the step surface, providing axial support for the cup from the main unit, while also concealing the trigger linkage, maximizing space utilization and improving the overall structural compactness.

[0016] In a preferred embodiment of a portable food processor, the housing includes a housing body and a mounting base that is reduced in diameter and protrudes upward relative to the inner diameter of the housing body. The bottom end of the trigger linkage can be moved downward to the outside of the mounting base, and the second magnet is located inside the mounting base and on the side close to the first magnet.

[0017] By placing the second magnet inside the mounting base and close to the first magnet, the first and second magnets are aligned laterally. When the first magnet moves to align with the second magnet, it generates a lateral inward driving force on the second magnet, pushing it inward to ensure contact between the contact piece and the spring piece. This fully utilizes the space inside the mounting base and helps to further improve the compactness of the overall structure.

[0018] In a preferred embodiment of a portable food processor, a second magnet is located at the outwardly extending end of the spring.

[0019] By placing the second magnet at the outward-extending end of the spring, the second magnet is furthest from the connection point between the spring and the switch body. Therefore, when the second magnet is subjected to force, the torque at the connection point is longer. This allows the second magnet to drive the spring to move towards the contact piece with less effort when the first magnet generates a repulsive force against the second magnet. This ensures that the contact piece and the spring piece make rapid and stable contact, improves trigger sensitivity, and further enhances the reliability of the entire machine.

[0020] In a preferred embodiment of a portable food processor, the cup body includes an inner cup and a housing covering the outside of the inner cup, and a trigger linkage is located between the inner cup and the housing.

[0021] By designing the cup body to include an inner cup and a shell covering the outer side of the inner cup, the shell protects the inner cup while creating a noise-reducing and heat-insulating space between the inner cup and the shell. This effectively reduces noise generated within the inner cup, minimizing its transmission to the outside. It also provides heat insulation, preventing burns from the hot shell and maintaining the temperature inside the inner cup for comfortable drinking even after extended use. Furthermore, the trigger lever is concealed and protected between the inner cup and the shell, preventing accidental activation and further enhancing operational reliability.

[0022] In a preferred embodiment of a portable food processor, the housing has an axially extending and outwardly protruding protrusion, the inner side of the protrusion and the outer wall of the inner cup forming a receiving cavity, and a trigger linkage is installed in the receiving cavity.

[0023] By providing an axially extending and outwardly protruding protrusion in the housing, the inner side of the protrusion and the outer wall of the inner cup form a receiving cavity, and the trigger link is installed in the receiving cavity, so that there is enough space between the inner cup and the housing for installing the trigger link, and the situation that the inner cup is recessed inward to accommodate the trigger link, which would reduce the capacity of the inner cup, is avoided. While ensuring that the capacity of the inner cup remains unchanged, the installation stability of the trigger link is improved, and the overall structural design is further optimized.

[0024] In a preferred embodiment of a portable food processor, a mounting bracket is fitted onto the inner wall of the bottom end of the housing, the bottom end of the inner cup abuts against the bottom of the mounting bracket, the mounting bracket is provided with a fixing ring connected to the inner cup, and the fixing ring is provided with a clearance opening for the trigger linkage to pass through.

[0025] By providing a fixing ring that connects to the inner cup and a clearance opening for the trigger link to pass through, the mounting bracket can not only axially limit the bottom of the inner cup, but also limit the bottom of the trigger link after it passes through the clearance opening. This prevents the trigger link from shifting during movement, which could cause the first magnet to fail to accurately trigger the magnetic switch, ensuring the stability of the trigger link's movement and further improving the accuracy and reliability of the entire machine.

[0026] In a preferred embodiment of a portable food processor, the magnetic switch includes a switch body and a fixed bracket, with the switch body suspended from the top wall of the outer casing via the fixed bracket. Attached Figure Description

Detailed Implementation

[0037] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0038] 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.

[0039] like Figures 1 to 7 As shown, this utility model provides a portable food processor, including a main unit 3 with a motor 5 inside and a detachable grinding cup located above the main unit 3. The grinding cup includes a cup body 2 with a grinding chamber and a cup lid 1 detachably covering the cup body 2. The main unit includes a housing 31 that houses the motor 5. The cup lid 1 includes a lower cover 12 and an upper cover 11 movably connected above the lower cover 12. The lower cover 12 has an exhaust port 121 that connects the grinding chamber to the outside. The upper cover 11 can move relative to the lower cover 12 to open or close the exhaust port 121. The grinding cup is vertically through-hole shaped and its bottom end is detachably fixed to the top of the main unit 3. The main unit 3 has a magnetic control switch 6 electrically connected to the motor 5. The grinding cup has a trigger rod 4 that is axially arranged and movable. The bottom end of the trigger rod 4 has a first magnet 7. When the upper cover 11 opens the exhaust port 121, the upper cover 11 can push the trigger rod 4 downward and drive the first magnet 7 downward to trigger the magnetic control switch 6.

[0040] This application configures the cup lid 1 as including a lower lid 12 and an upper lid 11 movably connected above the lower lid 12. The lower lid 12 has an exhaust port 121 that connects the grinding chamber to the outside. The upper lid 11 can move relative to the lower lid 12 to open or close the exhaust port 121, allowing the user to flexibly control the opening and closing of the exhaust port 121 by rotating the upper lid 11 to meet the exhaust needs of different working states. For example, when the user needs to process food ingredients using the food processor, the upper lid 11 can be rotated to open the exhaust port 121 to release the gas generated during the grinding and heating processes, preventing the cup lid 1 from being lifted due to excessive pressure in the grinding chamber. At the same time, when the user is carrying or storing food, the upper lid 11 can be rotated to close the exhaust port 121 to prevent food from spilling, ensuring ease of use and safety, and improving the user experience. Furthermore, the grinding cup is designed to run vertically through the main unit 3, and its bottom end is detachably fixed to the top of the main unit 3. This allows users to detach the cup 2 from the main unit 3 after using the food processor, enabling deep cleaning of both the cup 2 and the main unit 3. Users can directly clean the grinding device, making cleaning more convenient and faster, and improving the user experience.

[0041] In addition, the main unit 3 is equipped with a magnetic control switch 6 electrically connected to the motor 5, and the grinding cup is equipped with a movable trigger rod 4 arranged along the axial direction. The bottom end of the trigger rod 4 is equipped with a first magnet 7. When the upper cover 11 opens the exhaust port 121, the upper cover 11 can push the trigger rod 4 downward and drive the first magnet 7 downward to trigger the magnetic control switch 6. This ensures that the user can only push the trigger rod 4 and drive the first magnet 7 to trigger the magnetic control switch 6 when the exhaust port 121 is opened and the cup cover 1 is fastened to the cup body 2. Only then can the motor 5 be started to process the food. This ensures that the gas can be smoothly discharged through the exhaust port 121 during food processing, ensuring the stability of food processing and avoiding the situation where food processing is carried out when the exhaust port 121 is not open, which would cause excessive pressure in the grinding chamber. At the same time, it avoids the motor 5 starting due to misoperation and improves operational safety. Compared to existing designs that use a push rod to press down on the magnetic switch 6 to start the motor 5, this application achieves a non-contact triggering function through the cooperation of the magnetic switch 6 and the trigger linkage 4. This eliminates the need for openings at the bottom of the cup body 2 and the top of the main unit 3 to allow the push rod to pass through, thus ensuring the structural integrity of the cup body 2 and the main unit 3. This, in turn, ensures the airtightness of both, preventing water stains from entering the main unit 3 through openings during machine cleaning and causing electrical components to become damp, malfunction, or even be damaged. This provides waterproof protection for the entire machine, helps extend its service life, and ensures the stability of the food processing machine's operation.

[0042] As a preferred embodiment of this application, such as Figure 2As shown, the outer casing 31 includes an outer casing 31 body with an open top and a heating plate 34 fixed at the open top of the outer casing 31 body. The heating plate 34 has a crushing blade connected to the motor shaft of the motor in the middle. The magnetic control switch 6 is located between the outer casing 31 and the heating plate 34.

[0043] By directly fixing the heating plate 34 to the opening of the outer casing 31, the heating plate 34 serves as the top wall of the main unit 3 and the bottom wall of the grinding chamber, greatly simplifying the overall structure and contributing to the improved compactness of the machine, especially the reduction in axial dimensions. Simultaneously, the magnetic switch 6 is located between the outer casing 31 and the heating plate 34, maximizing the use of space within the outer casing 31 and further enhancing the compactness of the food processor, making it more convenient for users to carry.

[0044] It should be noted that this application does not specifically limit the manner in which the upper cover 11 opens or closes the exhaust port 121, nor the manner in which the upper cover 11 pushes the trigger rod; these can be any of the following embodiments:

[0045] Example 1: As Figure 7 As shown, in this embodiment, the upper cover 11 can be flipped relative to the lower cover 12 to open or close the exhaust port 121, and the upper cover 11 is provided with a downwardly extending top plate. When the upper cover 11 opens the exhaust port 121 and is pressed into place, the top plate can push the trigger linkage 4 to move downward to trigger the magnetic switch 6.

[0046] Example 2: As Figure 1 , Figure 2 As shown, in this embodiment, the upper cover 11 is provided with a trigger part 112 extending downward, the lower cover 12 is provided with an axially penetrating exhaust port 121, and the upper cover 11 is provided with an axially penetrating vent 111. The upper cover 11 can rotate relative to the lower cover 12 so that the vent 111 coincides with or is misaligned with the exhaust port 121 to open or close the exhaust port 121. At the same time, when the upper cover 11 rotates to open the exhaust port 121, the trigger part 112 can push the trigger linkage 4 to move downward to trigger the magnetic switch 6.

[0047] As a preferred embodiment of this application, such as Figure 3 , Figure 5 As shown, the magnetic switch 6 includes a switch body 61 with contacts and a spring 62 extending outward from the body. The spring 62 is provided with a second magnet 8, and the magnetic poles of the first magnet 7 and the second magnet 8 are the same on the side that are close to each other.

[0048] By configuring the magnetic switch 6 as a switch body 61 with contacts and a spring 62 extending outward from the body, with a second magnet 8 on the spring 62, and the first magnet 7 and the second magnet 8 having the same magnetic poles on their adjacent sides, when the first magnet 7 moves downward with the trigger rod 4, the first magnet 7 generates a repulsive force on the second magnet 8 and pushes the second magnet 8 toward the contacts until the contacts contact the spring 62, thereby closing the circuit and starting the motor 5, ensuring accurate operation and realizing the remote triggering of the magnetic switch 6. At the same time, when the trigger rod 4 moves upward, the repulsive force of the first magnet 7 on the second magnet weakens, and the second magnet 8 resets under the elastic force of the spring 62, the contacts separate from the spring 62, the circuit is broken, and the motor 5 stops working, further improving the convenience and safety of operation.

[0049] It should be noted that this application does not specifically limit the relative positions of the first magnet 7 and the second magnet 8, which can be any of the following embodiments:

[0050] Example 1: As Figure 3 , Figure 5 As shown, in this embodiment, the vertical projection of the first magnet 7 falls at least partially into the second magnet 8.

[0051] By setting the vertical projection of the first magnet 7 to at least partially fall into the second magnet 8, the first magnet 7 and the second magnet 8 are at least partially overlapped in the vertical direction. This allows the first magnet 7 to more effectively generate a repulsive force on the second magnet 8 when it moves downward, ensuring that the contact piece and the spring piece 62 make rapid contact, the circuit closes precisely, and the motor 5 starts stably. At the same time, it avoids starting delays or failures caused by magnet misalignment, further improving the reliability of operation and user experience.

[0052] Furthermore, such as Figure 3 , Figure 5 As shown, the outer casing 31 includes the outer casing 31 body and the mounting base 32, which is smaller in diameter and convex upward relative to the inner diameter of the outer casing 31 body. The bottom end of the mounting base 32 is connected to the top end of the outer casing 31 body through a stepped surface 33. The first magnet 7 is located directly above the stepped surface 33, and the second magnet 8 is located directly below the stepped surface 33.

[0053] By positioning the first magnet 7 directly above the step surface 33 and the second magnet 8 directly below it, ensuring their vertical alignment, the range of magnetic force is maximized, improving the response speed and stability of the magnetic switch 6. This further optimizes the precise control of the motor 5's start and stop, enhancing the overall smoothness and durability of the machine. Simultaneously, the bottom of the cup body 2 abuts against the step surface 33, providing axial support for the cup body 2 from the main unit 3. This also allows for the concealment of the trigger linkage 4, maximizing space utilization and improving the overall structural compactness.

[0054] Example 2: In this example, the outer shell 31 includes the outer shell 31 body and the mounting base 32, which is smaller in diameter and convex upward relative to the inner diameter of the outer shell 31 body. The bottom end of the trigger link 4 can be moved downward to the outside of the mounting base 32. The second magnet 8 is located inside the mounting base 32 and close to the side of the first magnet 7.

[0055] By placing the second magnet 8 inside the mounting base 32 and close to the first magnet 7, the first magnet 7 and the second magnet 8 are aligned laterally. When the first magnet 7 moves to align with the second magnet 8, the first magnet 7 generates a lateral inward driving force on the second magnet 8 and pushes the second magnet 8 inward, ensuring that the contact piece contacts the spring piece 62. This achieves full utilization of the inner space of the mounting base 32 and helps to further improve the compactness of the overall structure.

[0056] As a preferred embodiment of this application, such as Figure 3 , Figure 5 , Figure 6 As shown, the second magnet 8 is located at the end of the outward extension of the spring piece 62.

[0057] By placing the second magnet 8 at the outwardly extending end of the spring 62, the second magnet 8 is furthest from the connection point between the spring 62 and the switch body 61. Therefore, when the second magnet 8 is subjected to force, the torque at the connection point is longer. This allows the second magnet 8 to drive the spring 62 to move towards the contact piece with less effort when the first magnet 7 generates a repulsive force against the second magnet 8. This ensures that the contact piece and the spring 62 make rapid and stable contact, improves trigger sensitivity, and further enhances the reliability of the entire machine.

[0058] As a preferred embodiment of this application, such as Figure 2 As shown, the cup body 2 includes an inner cup 22 and a housing 21 covering the outside of the inner cup 22, and the trigger linkage 4 is located between the inner cup 22 and the housing 21.

[0059] By configuring the cup body 2 to include an inner cup 22 and a shell 21 covering the outside of the inner cup 22, the shell 21 protects the inner cup 22. Simultaneously, a noise-reducing and heat-insulating space is formed between the inner cup 22 and the shell 21, effectively reducing noise generated within the inner cup 22 and minimizing its transmission to the outside. This space also provides heat insulation, preventing burns from the shell 21 when held, and maintaining the temperature within the inner cup 22 for comfortable drinking even after extended use. Furthermore, the trigger lever 4 is positioned between the inner cup 22 and the shell 21, protecting and concealing it to prevent accidental activation and further enhancing operational reliability.

[0060] Furthermore, such as Figure 1 , Figure 2As shown, the housing 21 has a protrusion 211 that extends axially and protrudes outward. The inner side of the protrusion 211 and the outer side wall of the inner cup 22 form a receiving cavity, and the trigger linkage 4 is installed in the receiving cavity.

[0061] By providing an axially extending and outwardly protruding protrusion 211 in the housing 21, the inner side of the protrusion 211 and the outer side wall of the inner cup 22 form a receiving cavity, and the trigger link 4 is installed in the receiving cavity, so that there is enough space between the inner cup 22 and the housing 21 for installing the trigger link 4, and the situation that the inner cup 22 is recessed inward to accommodate the trigger link 4, which would reduce the capacity of the inner cup 22, is avoided. While ensuring that the capacity of the inner cup 22 remains unchanged, the installation stability of the trigger link 4 is improved, and the overall structural design is further optimized.

[0062] As a preferred embodiment, such as Figure 3 As shown, a mounting bracket 9 is fitted on the inner wall of the bottom end of the housing 21, and the bottom end of the inner cup 22 abuts against the bottom of the mounting bracket 9. The mounting bracket 9 is provided with a fixing ring connected to the inner cup 22, and the fixing ring is provided with a clearance opening for the trigger linkage 4 to pass through.

[0063] By providing a fixing ring for the mounting bracket 9 to connect with the inner cup 22, and the fixing ring having a clearance opening for the trigger link 4 to pass through, the mounting bracket 9 can not only axially limit the bottom end of the inner cup 22, but also limit the bottom end of the trigger link 4 after it passes through the clearance opening. This prevents the trigger link 4 from shifting during movement, which could cause the first magnet 7 to fail to accurately trigger the magnetic switch 6. This ensures the stability of the movement of the trigger link 4 and further improves the accuracy and reliability of the entire machine.

[0064] It should be noted that this application does not specifically limit the assembly method of the magnetic switch 6. As one preferred embodiment of this application, such as... Figure 6 As shown, the magnetic switch 6 includes a switch body 61 and a fixing bracket 63. The switch body 61 is suspended from the top wall of the housing 31 by the fixing bracket 63.
