Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good waterproof performance. 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 CN117652896A discloses a reliable food processor. This machine incorporates a microswitch within the main unit to control the motor's on / off state. The lid has a trigger structure, and the cup body has a follower that moves with the trigger structure. The trigger structure, through the follower, drives the microswitch, ensuring that the microswitch is only triggered when the lid is fully closed, thus guaranteeing the safety and stability of food processing. Similarly, the applicant's earlier patent application CN220124565U discloses a reliably assembled food processor. This machine incorporates a microswitch within the handle to control the motor's on / off state, and the microswitch is only triggered after the lid is fully screwed on, enabling food processing. Both of these microswitches are connected to the motor control board via low-voltage wiring. After the microswitch actuates, it transmits a low-voltage signal to the control board, which then controls the motor. This results in a delay in the motor's 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 / T 4706.19-2024 Safety of household and similar electrical appliances - Part 19: Particular requirements for liquid heaters), it is required that the motor 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 the neutral or live wire, so that the motor can stop synchronously the instant the microswitch is disconnected. Faced with this problem, those skilled in the art can easily conceive of improving the existing microswitch by directly connecting it to the motor via a high-voltage wire. The existing method of connecting to the motor via a low-voltage wire has a lower voltage, so if moisture or other contaminants enter during use, the microswitch has less impact and can still function normally, thus requiring less waterproofing. However, by changing the low-voltage wire to a high-voltage wire, the microswitch is directly connected to the mains power, resulting in a higher voltage, thus requiring greater waterproofing. If either of the above two solutions is adopted directly, when the microswitch is placed inside the main unit, cleaning water can easily enter the microswitch through the through-hole during the user's cleaning process, causing the microswitch to become damp and prone to short circuits upon reuse. When the microswitch is placed inside the handle, water vapor generated during food processing can also enter the microswitch through the through-hole, causing it to become damp and short circuits, rendering it unusable and severely impacting the user experience. Furthermore, if a waterproof microswitch is used, its complex structure and large size would occupy a significant amount of space inside the handle, posing another challenge in the research and development process: how to install and trigger the microswitch within such a small space. Utility Model Content

[0004] The purpose of this utility model is to provide a food processing machine with good waterproof performance, in order to solve the problem of how to install the micro switch in a small space while meeting the waterproof requirements after the micro switch is connected to high voltage, under the premise that the existing food processing machine uses a micro switch 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 good waterproof performance, including a main unit with a motor and a detachable cup body located above the main unit. The cup body contains a crushing device, which can be driven to rotate by the motor. The cup body includes a crushing cup, a handle fixed to the side wall of the crushing cup, and a cup lid covering the crushing cup. The handle contains a micro switch with a trigger button, which is horizontally positioned. The handle also contains a trigger linkage extending axially, with the micro switch located below the trigger linkage. After the cup lid is closed, it presses against the trigger linkage to trigger the trigger button. The handle also contains a water-blocking structure located above the micro switch, and the water-blocking structure has a clearance for the trigger linkage to pass through.

[0006] This application incorporates a microswitch within the handle. Preferably, the microswitch is connected in series with the motor via a high-voltage circuit, allowing for a rapid power cut-off when the lid is opened. This ensures the crushing device stops rotating immediately, meeting the requirements of the new national standard. Simultaneously, the handle also features an axially extending trigger rod, with the microswitch located below it. This allows the trigger rod to move rapidly when the lid is closed or opened, precisely triggering or releasing the microswitch. This ensures a rapid and stable response from the microswitch. Furthermore, the trigger rod increases the distance between the microswitch and the lid, making it less likely for moisture generated during food processing to contact the microswitch, effectively reducing the risk of moisture damage and improving overall waterproof performance. Meanwhile, the micro switch is equipped with a trigger button, which is horizontally positioned to allow the micro switch to be installed inside the handle. When the lid is closed, it presses against the trigger linkage to activate the trigger button. The horizontally positioned trigger button prevents water from dripping directly onto the trigger button during food processing or cleaning, and thus prevents water from entering the micro switch through the gap between the trigger button and the micro switch housing. This greatly improves the waterproof performance of the micro switch, effectively avoiding short circuits caused by moisture intrusion, and further enhancing the safety and stability of the food processor in humid environments.

[0007] Furthermore, the handle is equipped with a water-blocking structure located above the microswitch. This structure effectively blocks water droplets moving downwards from the top of the handle, preventing them from directly contacting the microswitch and further enhancing its protection. This improves the overall waterproof performance. The water-blocking structure also features a clearance opening for the trigger rod to pass through, ensuring unobstructed movement and allowing water droplets moving downwards along the rod to be scraped off, further preventing downward movement and enhancing the microswitch's waterproof protection.

[0008] In a preferred embodiment of a waterproof food processing machine, the clearance opening is vertically offset from the trigger button.

[0009] By setting the clearance opening vertically to be offset from the trigger button, water droplets falling downwards through the clearance opening can avoid the trigger button, thereby further reducing the risk of water entering the micro switch and further improving the waterproof protection effect of the micro switch.

[0010] In a preferred embodiment of a food processing machine with good waterproof performance, the water-blocking structure is provided with an upward-facing limiting groove, the clearance opening is provided on the bottom wall of the limiting groove, the triggering linkage is provided with a radially outward-protruding ring rib, and the handle is also provided with a return spring, one end of the return spring abutting against the bottom end of the ring rib, and the other end abutting against the bottom wall of the limiting groove.

[0011] By incorporating an upward-facing limiting groove into the water-blocking structure, the groove achieves a certain water storage capacity. This allows water blocked by the structure to be temporarily stored within the groove, preventing further downward flow and thus enhancing the waterproofing effect. Simultaneously, a return spring is installed inside the handle. One end of the return spring abuts against the bottom of the ring rib, and the other end abuts against the bottom wall of the limiting groove. This allows the trigger linkage to automatically reset via the return spring. Furthermore, the water-blocking structure, while providing water protection, also provides positioning support for the return spring, eliminating the need for a separate structural component to support it. This simplifies the overall structure and reduces production costs.

[0012] In a preferred embodiment of a food processing machine with good waterproof performance, the outer diameter of the ring rib is larger than the inner diameter of the clearance opening; or,

[0013] The water-blocking structure includes a horizontal plate located at the avoidance opening and a ring rib extending upward from the outer periphery of the horizontal plate. The ring rib and the horizontal plate enclose a limiting groove.

[0014] By setting the outer diameter of the ring rib to be larger than the inner diameter of the clearance opening, when the trigger rod moves upward, the ring rib can form a limiting fit with the bottom wall of the clearance opening, thus sealing the clearance opening and preventing water stains from continuing to seep downward through it, further improving the overall sealing performance. Simultaneously, when the trigger rod moves downward, if water stains move downward through the clearance opening, the ring rib can block that portion of the water stains, preventing them from flowing further downward, thereby achieving double waterproof protection.

[0015] In a preferred embodiment of a food processing machine with good waterproof performance, a sealing ring is also provided between the clearance port and the trigger linkage.

[0016] By providing a sealing ring between the clearance port and the trigger link, the clearance port and the trigger link can be sealed together. This allows water to flow downwards above the water-blocking structure. If the water flows to the clearance port, the sealing ring can block the water, preventing it from flowing further downwards and providing further waterproof protection for the micro switch.

[0017] In a preferred embodiment of a waterproof food processing machine, the cup lid is provided with an outwardly extending trigger rib, and the top of the handle is provided with a through hole for the trigger rib to extend into and press against the trigger linkage to move downward. The through hole is vertically offset from the trigger button.

[0018] By incorporating an outwardly extending trigger rib on the cup lid and a through hole at the top of the handle for the trigger rib to extend into and press against the trigger linkage to move downwards, the trigger rib can reach into the through hole and contact the trigger linkage when the cup lid is closed. This pushes the trigger linkage downwards, triggering the micro switch and ensuring that the cup lid is fully closed before operation. Furthermore, the through hole is vertically offset from the trigger button, preventing water entering the handle through the through hole from dripping directly onto the trigger button, further enhancing the protection of the micro switch.

[0019] In a preferred embodiment of a waterproof food processor, the trigger button faces the grinding cup, and the trigger linkage includes a driven part extending vertically and a trigger part connected to the end of the driven part, which bends inward and extends downward to the space between the trigger button and the grinding cup.

[0020] By setting the trigger button to face the crushing cup, the trigger linkage includes a driven part extending vertically and a trigger part connected to the end of the driven part, which bends inward and extends downward to the space between the trigger button and the crushing cup. This allows water stains adhering to the trigger linkage to flow downwards and move vertically downwards along the driven part under the action of gravity. When the water stains reach the end of the driven part, due to the bending structure design of the trigger part, the water stains will drip downwards from the end of the driven part due to inertia instead of continuing to flow downwards along the trigger part. This further prevents water stains from dripping onto the trigger button and further improves the waterproof performance of the micro switch.

[0021] In a preferred embodiment of a waterproof food processing machine, the micro switch is connected in series with the motor via a neutral wire.

[0022] By setting the micro switch to be connected in series with the motor via the neutral wire, the power supply to the motor can be quickly cut off when the lid is opened, thus cutting off the high voltage and ensuring that the crushing device stops rotating immediately, meeting the requirements of the new national standard.

[0023] In a preferred embodiment of a waterproof food processing machine, the motor is a brushless motor, and the main unit is also equipped with a control board connected to the brushless motor. The control board includes a main control module and a brushless motor drive module. The micro switch, the main control module, the brushless motor drive module and the brushless motor are electrically connected in sequence. The brushless motor drive module and the micro switch are also electrically connected through a first energy storage module.

[0024] By using a brushless motor compared to a traditional series motor, the weight of the motor can be significantly reduced, improving the portability of the entire machine and reducing its footprint, thus reducing the overall size of the machine. It also reduces noise and enhances the user experience. Furthermore, the main unit includes a control board connected to the brushless motor. This control board comprises a main control module and a brushless motor drive module. A microswitch, the main control module, the brushless motor drive module, and the brushless motor are sequentially and electrically connected. The brushless motor drive module and the microswitch are also electrically connected through a first energy storage module. This ensures that when the microswitch is turned off after use, the brushless motor is directly disconnected via the microswitch, meeting the requirements of the new national standard. The first energy storage module can continue to discharge and temporarily supply power to the brushless motor drive module, maintaining it at the normal operating voltage. This effectively prevents the brushless motor drive module from being directly de-energized after the microswitch disconnects the high voltage, thus protecting the brushless motor drive module from damage such as tube explosion or burnout.

[0025] In a preferred embodiment of a waterproof food processing machine, a second energy storage module is electrically connected between the main control module and the micro switch, and the energy storage of the first energy storage module is greater than that of the second energy storage module.

[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 to provide a full understanding of this invention. However, this invention may also be implemented in other ways different from those described herein.

[0037] Therefore, the scope of protection of this utility model is not limited to the specific embodiments disclosed below.

[0038] like Figures 1 to 6 As shown, this utility model provides a food processing machine with good waterproof effect, including a main unit 4 with a motor inside and a detachable cup body located above the main unit 4. The cup body is equipped with a crushing device, which can be driven by the motor to rotate. The cup body includes a crushing cup 3, a handle 2 fixed to the side wall of the crushing cup 3, and a cup lid 1 covering the crushing cup 3. The handle 2 is equipped with a micro switch 6, which has a trigger button 61 and is horizontally arranged. The handle 2 is also equipped with a trigger linkage 5 extending axially. The micro switch 6 is located below the trigger linkage 5. After the cup lid 1 is closed, it presses against the trigger linkage 5 to trigger the trigger button 61. The handle 2 is also equipped with a water-blocking structure 7 located above the micro switch 6, and the water-blocking structure 7 has a clearance opening 72 for the trigger linkage 5 to pass through.

[0039] This application incorporates a microswitch 6 within the handle 2. Preferably, the microswitch 6 is connected in series with the motor via a high-voltage circuit, enabling the motor power to be quickly cut off when the lid 1 is opened, thus ensuring the crushing device stops rotating immediately and meeting the requirements of the new national standard. Simultaneously, the handle 2 also includes an axially extending trigger rod 5, with the microswitch 6 located below it. This allows the lid 1 to move the trigger rod 5 rapidly when closing and opening, precisely triggering or releasing the microswitch 6. This ensures the microswitch 6's response is rapid and stable. Furthermore, the trigger rod 5 increases the distance between the microswitch 6 and the lid 1, making it less likely for moisture generated during food processing to contact the microswitch 6, effectively reducing the risk of moisture damage and improving overall waterproof performance. Meanwhile, the micro switch 6 is equipped with a trigger button 61, which is horizontally positioned to allow the micro switch 6 to be installed inside the handle 2. After the cup lid 1 is closed, it presses against the trigger linkage 5 to trigger the trigger button 61. The horizontally positioned trigger button 61 prevents water stains that enter the handle 2 through the through hole 21 above the handle 2 during food processing or cleaning from dripping directly onto the trigger button 61. Consequently, water stains cannot enter the micro switch 6 through the gap between the trigger button 61 and the housing of the micro switch 6, thus greatly improving the waterproof performance of the micro switch 6 and effectively avoiding short circuits caused by moisture intrusion. This further enhances the safety and stability of the food processor in humid environments.

[0040] Furthermore, the handle 2 is equipped with a water-blocking structure 7 located above the micro switch 6. This structure effectively blocks water droplets moving downwards from the top of the handle 2, preventing them from directly contacting the micro switch 6 and further enhancing the protection of the micro switch 6, thus improving the overall waterproof performance. Simultaneously, the water-blocking structure 7 has a clearance opening 72 for the trigger linkage 5 to pass through, ensuring that the trigger linkage 5 is not obstructed during its vertical movement. Water droplets moving downwards along the trigger linkage 5 can be scraped off through the clearance opening 72, preventing them from moving further downwards and further enhancing the waterproof protection of the micro switch 6.

[0041] As a preferred embodiment of this application, such as Figure 2 , Figure 5 As shown, the clearance 72 is vertically offset from the trigger button 61.

[0042] By setting the clearance opening 72 vertically to be offset from the trigger button 61, water dripping down through the clearance opening 72 can avoid the position of the trigger button 61, thereby further reducing the risk of water entering the micro switch 6 and further improving the waterproof protection effect of the micro switch 6.

[0043] As a preferred embodiment of this application, such as Figure 5 As shown, the water-blocking structure 7 is provided with an upward-facing limiting groove 71, and an avoidance opening 72 is provided on the bottom wall of the limiting groove 71. The triggering link 5 is provided with a radially outward-protruding ring rib 51. The handle 2 is also provided with a return spring 8. One end of the return spring 8 abuts against the bottom end of the ring rib 51, and the other end abuts against the bottom wall of the limiting groove 71.

[0044] By providing an upward-facing limiting groove 71 to the water-blocking structure 7, the limiting groove 71 can achieve a certain water storage capacity, allowing water stains blocked by the water-blocking structure 7 to be temporarily stored in the limiting groove 71, preventing them from continuing to flow downwards, thereby further improving the waterproof effect. At the same time, a return spring 8 is also provided inside the handle 2. One end of the return spring 8 abuts against the bottom end of the ring rib 51, and the other end abuts against the bottom wall of the limiting groove 71, so that the trigger linkage 5 can achieve an automatic reset function through the return spring 8. In addition to providing water-blocking protection, the water-blocking structure 7 can also provide positioning support for the return spring 8, eliminating the need for a separate structural component to support the return spring 8, thereby simplifying the overall structure and reducing production costs.

[0045] Furthermore, such as Figure 5 As shown, the outer diameter of the ring reinforcement 51 is larger than the inner diameter of the clearance opening 72.

[0046] By setting the outer diameter of the ring rib 51 to be larger than the inner diameter of the clearance opening 72, when the trigger rod 5 moves upward, the ring rib 51 can form a limiting fit with the bottom wall of the clearance opening 72, thus sealing the clearance opening 72 and preventing water stains from continuing to penetrate downward through the clearance opening 72, further improving the overall sealing performance. At the same time, when the trigger rod 5 moves downward, if water stains move downward through the clearance opening 72, the ring rib 51 can block that part of the water stains, preventing them from flowing further downward, thus achieving double waterproof protection.

[0047] As a preferred embodiment of this implementation, such as Figure 5 As shown, the water-blocking structure 7 includes a horizontal plate provided at the avoidance opening 72 and a ring rib 51 extending upward from the outer periphery of the horizontal plate. The ring rib 51 and the horizontal plate enclose each other to form a limiting groove 71.

[0048] In a preferred embodiment of this application, a sealing ring is also provided between the clearance opening 72 and the trigger linkage 5.

[0049] By providing a sealing ring between the clearance opening 72 and the trigger link 5, the clearance opening 72 and the trigger link 5 can achieve a sealed contact through the sealing ring. This allows water stains to move downwards above the water-blocking structure 7. If the water stains flow to the clearance opening 72, the sealing ring can block the water stains, thus preventing them from flowing further downwards and providing further waterproof protection for the micro switch 6.

[0050] It should be noted that this application does not specifically limit the structure of the sealing ring. It can be sleeved on the outside of the triggering rod 5 and extended along the axial direction of the triggering rod 5. During the reciprocating movement of the triggering rod 5, the sealing ring also moves with the triggering rod 5 to ensure that the sealing ring is always in a sealing effect; or the sealing ring can be fixed on the clearance opening 72, which will not be described in detail here.

[0051] As a preferred embodiment of this application, such as Figure 2 , Figure 3 , Figure 6 As shown, the cup lid 1 is provided with an outwardly extending trigger rib 11, and the top of the handle 2 is provided with a through hole 21 for the trigger rib 11 to extend into and press against the trigger linkage 5 to move downward. The through hole 21 is vertically offset from the trigger button 61.

[0052] By providing an outwardly extending trigger rib 11 to the cup lid 1 and a through hole 21 at the top of the handle 2 for the trigger rib 11 to extend into and press against the trigger linkage 5 to move downward, the trigger rib 11 can extend into the through hole 21 and contact the trigger linkage 5 when the cup lid 1 is closed, thereby pushing the trigger linkage 5 downward and triggering the micro switch 6. This ensures that the cup lid 1 can only start working when it is fully closed. At the same time, the through hole 21 is vertically offset from the trigger button 61, so that water entering the handle 2 through the through hole 21 will not drip directly onto the trigger button 61, further improving the protection of the micro switch 6.

[0053] Furthermore, such as Figure 5 As shown, the trigger button 61 faces the crushing cup 3. The trigger link 5 includes a driven part 52 extending vertically and a trigger part 53 connected to the end of the driven part 52, which bends inward and extends downward to the space between the trigger button 61 and the crushing cup 3.

[0054] By setting the trigger button 61 to face the crushing cup 3, the trigger link 5 includes a driven part 52 extending vertically and a trigger part 53 connected to the end of the driven part 52, which bends inward and extends downward to the space between the trigger button 61 and the crushing cup 3. This allows water stains adhering to the trigger link 5 to flow downwards and move vertically downwards along the driven part 52 under the action of gravity. When the water stains flow to the end of the driven part 52, due to the bending structure design of the trigger part 53, the water stains will drip downwards from the end of the driven part 52 due to inertia instead of continuing to flow downwards along the trigger part 53. This further prevents water stains from dripping onto the trigger button 61 and further improves the waterproof performance of the micro switch 6.

[0055] It should be noted that this application does not specifically limit the connection between the micro switch 6 and the motor, and it can be any of the following embodiments:

[0056] Example 1: In this example, the micro switch 6 is connected in series with the motor via the neutral wire.

[0057] By setting the micro switch 6 to be connected in series with the motor via the neutral wire, the power supply to the motor can be quickly cut off when the cup lid 1 is opened, thereby cutting off the high voltage and ensuring that the crushing device stops rotating immediately, which meets the requirements of the new national standard.

[0058] Example 2: In this example, the motor is a brushless motor. The host 4 is also equipped with a control board connected to the brushless motor. The control board includes a main control module and a brushless motor drive module. The micro switch 6, the main control module, the brushless motor drive module and the brushless motor are electrically connected in sequence. The brushless motor drive module and the micro switch 6 are also electrically connected through the first energy storage module.

[0059] By using a brushless motor compared to a traditional series motor, the weight of the motor can be significantly reduced, improving the portability of the entire machine and reducing its footprint, thus reducing the overall size of the machine. It also reduces noise and enhances the user experience. Furthermore, the main unit 4 contains a control board connected to the brushless motor. This control board includes a main control module and a brushless motor drive module. Microswitch 6, the main control module, the brushless motor drive module, and the brushless motor are sequentially electrically connected. The brushless motor drive module and microswitch 6 are also electrically connected through a first energy storage module. This ensures that when the user finishes using the food processor, the brushless motor is directly disconnected via microswitch 6 when it is turned off, meeting the requirements of the new national standard. The first energy storage module can continue to discharge and temporarily supply power to the brushless motor drive module, maintaining it at the normal operating voltage. This effectively prevents the brushless motor drive module from being directly de-energized after microswitch 6 disconnects the high voltage, thus protecting the brushless motor drive module from damage such as tube explosion or burnout.

[0060] Furthermore, a second energy storage module is electrically connected between the main control module and the micro switch 6, and the energy storage of the first energy storage module is greater than that of the second energy storage module.

[0061] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
