Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] In existing food processing machines, the cup handle is usually equipped with a microswitch. When the cup lid is closed, the microswitch is triggered, and the motor is powered on to start operation. If the cup lid is not closed or is not properly closed, the microswitch cannot be triggered, and the motor remains de-energized to ensure safety. For example, in the small food processing machine disclosed in patent CN212213524U, the trigger switch is activated by the cup lid via a magnetic drive, and the microswitch is fixed to the upper part of the handle by a mounting bracket.

[0003] However, the current assembly method for microswitches involves first fixing the microswitch body to a mounting bracket, then horizontally embedding the two together into a pre-set mounting groove in the handle, with the swing arm of the microswitch facing the lid. Finally, the handle housing is tightened laterally using clips or screws, while the microswitch body is limited solely by the groove wall. Because the microswitch is limited only by the mounting groove, the initial position stability of the swing arm is poor after the microswitch is fixed, causing changes in the distance between the swing arm and the lid, resulting in deviations and decreased trigger reliability. Furthermore, this fixing method lacks a precise positioning reference, directly making it difficult to control the distance between the swing arm of the microswitch and the lid. If the distance between the swing arm of the micro switch and the cup lid is too large, the magnetic force of the magnet on the cup lid will be insufficient to drive the swing arm to complete the triggering action, resulting in an unreliable triggering problem where the motor still cannot start after the cup lid is closed. If the switch is pressed too hard during assembly, the distance between the two will be too small, causing the swing arm to be continuously squeezed by the mounting groove wall, resulting in a rebound jamming problem and inability to fully reset to the initial position. This may even cause the swing arm to continuously trigger the micro switch after the cup lid is opened, resulting in a safety problem where the motor is not powered off. Utility Model Content

[0004] This invention provides a food processing machine that solves the problems of poor assembly and positioning accuracy of microswitches in the prior art, difficulty in controlling the distance between the swing arm and the cup lid, resulting in unreliable microswitch triggering when the distance is too far, and safety issues such as the swing arm not being able to rebound and continuously triggering the microswitch when the distance is too close.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a cup body, a cup lid, a motor, and a crushing device. The crushing device is located inside the cup body and is driven by the motor. The cup body has a handle fixed to it. The upper part of the handle is provided with a mounting cavity, a micro switch located in the mounting cavity, and a mounting bracket. The micro switch is used to control the on / off state of the motor. The micro switch includes a body and a swing arm. One end of the swing arm is fixed to the body, and the other end forms a free end. After the cup lid is closed on the cup body, the swing arm is driven by magnetic force to trigger the micro switch to close. The micro switch is positioned above the mounting bracket, and the swing arm is positioned... On the side of the main body facing the cup, the mounting cavity is provided with a support and a guide rib. The mounting bracket is provided with a guide groove that cooperates with the guide rib to be inserted into the mounting cavity towards the cup. The support is supported below the mounting bracket. The mounting cavity is also provided with a limiting structure near the cup. The limiting structure abuts against the mounting bracket to prevent the mounting bracket from continuing to move towards the end wall of the mounting cavity in the insertion direction. The limiting structure also creates a spring space between the micro switch and the end wall of the mounting cavity to accommodate the swing arm. The swing arm swings between the initial position and the trigger position within the spring space.

[0006] The food processing machine provided by this utility model, on the one hand, provides clear guidance for the installation process of the mounting bracket by setting guide ribs in the mounting cavity and forming a precise fit with the guide groove of the mounting bracket, thus achieving fast and accurate installation; on the other hand, after installation, the guide ribs and guide grooves form axial limit, and the support part in the mounting cavity forms stable support for the bottom of the mounting bracket. Combined with the positioning design of the micro switch above the mounting bracket, it ensures that the relative position of the micro switch in the mounting cavity is accurate and the positioning is reliable, and can effectively resist vibration and avoid displacement during use.

[0007] On the other hand, the limiting structure near the cup body inside the mounting cavity abuts against the mounting bracket, forming a positioning reference for the micro switch. This precisely controls the insertion depth of the micro switch, achieving precise control of the distance between the swing arm and the cup lid. This avoids the problem of excessive insertion and excessive force during assembly, which could lead to an insufficient distance between the swing arm and the cup lid, and prevents the swing arm from remaining in a compressed state. The limiting structure creates a rebound space between the micro switch and the end wall of the mounting cavity, providing sufficient room for the swing arm to move between the initial and triggered positions. This prevents the swing arm from jamming due to limited space and avoids the safety hazard of the opening motor failing to shut off power due to insufficient rebound of the swing arm. It ensures smooth and precise triggering. Combined with the limiting of the guide ribs, guide grooves, and the supporting mounting bracket, this effectively reduces problems such as false triggering and failure to trigger the micro switch, improving the stability and reliability of the micro switch and enhancing the safety of the food processing machine.

[0008] In a preferred embodiment, the support portion includes a first support rib and a second support rib, the first support rib being higher than the second support rib to tilt and support the mounting bracket, and the micro switch tilting with the mounting bracket and extending upward from the connecting end of the swing arm toward the free end.

[0009] The support section includes a first support rib and a second support rib, providing multi-point support for the mounting bracket and improving its stability. Furthermore, the varying heights of the first and second support ribs allow the mounting bracket to be tilted at a preset angle, utilizing the diagonal space of the mounting cavity to meet the assembly requirements of the mounting bracket. This space-saving and compact design contributes to the miniaturization of the handle. Moreover, the microswitch extends upwards from the connecting end of the swing arm towards the free end, raising the free end of the swing arm and making it easier to approach the cup lid. This ensures effective triggering between the cup lid and the microswitch, resulting in sensitive and reliable triggering.

[0010] In a preferred embodiment, the lower side of the mounting bracket abuts against the cavity sidewall of the mounting cavity, and the higher side of the mounting bracket abuts against a limiting rib on another cavity sidewall of the mounting cavity.

[0011] The lower side of the mounting bracket abuts against the sidewall of the mounting cavity, while the higher side abuts against a limiting rib on the other sidewall of the mounting cavity. This ensures reliable positioning of the mounting bracket on both sides, guaranteeing accurate positioning and reliable triggering of the microswitch. By utilizing an inclined microswitch, with the lower side abutting against the sidewall of the mounting cavity and the higher side abutting against the limiting rib, friction during installation is reduced, enabling smooth and rapid installation.

[0012] In a preferred embodiment, the edge of the mounting bracket is provided with an upwardly extending enclosure, and the guide groove is provided on the outer surface of the enclosure.

[0013] The enclosure provides lateral restraint for the micro switch, improving the positioning stability between the micro switch and the mounting bracket and preventing displacement of the micro switch relative to the mounting bracket. The enclosure also provides more installation space, allowing the guide groove to be placed on the enclosure for efficient structural utilization. It also facilitates the installation of the mounting bracket, ensuring precise positioning of the mounting bracket and micro switch, smooth assembly, and more reliable micro switch triggering.

[0014] In a preferred embodiment, the guide groove is located on the bottom surface of the mounting bracket, and the guide rib is disposed on the support portion.

[0015] The guide groove is located on the bottom surface of the mounting bracket, and the guide ribs are set on the support part, so that the guidance and support limit are combined. While the support part supports the mounting bracket, the guide ribs on its surface directly match the guide groove on the bottom surface of the bracket, which simplifies the overall structure and avoids setting additional guide grooves in other parts. Moreover, the guide action point is close to the support surface, which enhances the stability during the assembly process, prevents the mounting bracket from swinging when it is installed, and ensures reliable limit.

[0016] In a preferred embodiment, the limiting structure includes a limiting boss located between the end wall of the mounting cavity and the mounting bracket, the limiting boss being misaligned with the swing arm, and the limiting boss abutting against the end face of the mounting bracket facing the cup body.

[0017] The limiting structure uses a limiting boss located between the end wall of the mounting cavity and the mounting bracket. It can directly and accurately abut against the end face of the mounting bracket to prevent the mounting bracket from being over-inserted, thereby achieving precise control of the distance between the swing arm and the cup lid. The triggering of the micro switch is more reliable. The limiting boss and the swing arm are misaligned, which does not interfere with the swing arm's swing in the rebound space, and allows the limiting boss to directly limit the mounting bracket using this space. The structure is compact and simple.

[0018] In a preferred embodiment, the support portion is a support rib, and the limiting boss is integrally connected to the support rib.

[0019] By integrating the limiting boss with the support rib, the structure is integrated, simplifying the arrangement of the limiting rib in the mounting cavity, saving space, and achieving reliable limiting of the micro switch in the narrow mounting space of the handle.

[0020] In a preferred embodiment, the limiting structure includes a limiting post protruding from the end wall of the mounting cavity, and the mounting bracket has a downwardly extending extension wall that abuts against the limiting post.

[0021] More preferably, the limiting post is a stud, and the extension wall is provided with a through hole for the screw to pass through, and the screw and the stud clamp the extension wall of the mounting bracket.

[0022] The mounting bracket features a downward-extending extension wall. This extension wall abuts against a limiting post on the end wall of the mounting cavity, preventing the mounting bracket from being over-inserted. The structure is simple. The limiting post is a stud, and screws passing through holes in the extension wall and locking to the stud enhance the fixation between the mounting bracket and the mounting cavity, preventing the mounting bracket from loosening and ensuring reliable and accurate positioning and triggering of the microswitch.

[0023] In a preferred embodiment, the handle includes a handle bracket fixed to the cup body and a handle cover that engages with the handle bracket to form the mounting cavity. The limiting structure is disposed on the handle bracket, and the handle cover and the limiting structure clamp the mounting bracket.

[0024] The handle includes a handle bracket and a handle cover, which together form a mounting cavity to facilitate the installation of the mounting bracket and the micro switch. After installation, the handle cover hides both components to prevent exposure. At the same time, the handle cover and the limiting structure clamp the mounting bracket to ensure reliable fixation and prevent loosening.

[0025] In a preferred embodiment, the mounting bracket is provided with an upwardly protruding positioning post, and the body of the micro switch is provided with a positioning hole, into which the positioning post is inserted.

[0026] By utilizing the cooperation of positioning pins and positioning holes, the micro switch and the mounting bracket are limited, making the micro switch and the mounting bracket a single module with a simple structure and easy and quick assembly. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] like Figure 1 , 2 As shown, in one embodiment, this utility model provides a food processing machine, including a cup body 10, a cup lid 20, a motor, and a pulverizing device. The pulverizing device is located inside the cup body 10 and is driven by the motor. The pulverizing device uses a pulverizing blade or a moving grinding head. A handle 30 is fixed to the cup body 10. The upper part of the handle 30 is provided with a mounting cavity 301, a micro switch 40 located in the mounting cavity 301, and a mounting bracket 50. The micro switch 40 is used to control the on / off power supply of the motor. Figure 3 , 4 As shown, the micro switch 40 includes a body 41 and a swing arm 42. One end of the swing arm 42 is fixed to the body 41, and the other end forms a free end. After the cup lid 20 is closed on the cup body 10, the swing arm 42 is driven by magnetic force to trigger the micro switch 40 to close. Figure 2 , 3 As shown, the micro switch 40 is positioned above the mounting bracket 50, and the swing arm 42 is located on the side of the body 41 facing the cup body 10. Figure 5 , 6 As shown in Figure 7, the mounting cavity 301 is provided with a support 302 and a guide rib 303. The mounting bracket 50 is provided with a guide groove 501 that mates with the guide rib 303 so that it is inserted into the mounting cavity 301 toward the cup body 10. The support 302 is supported below the mounting bracket 50. Figure 3 As shown, the mounting cavity 301 is also provided with a limiting structure 70 near the cup body 10. The limiting structure 70 abuts against the mounting bracket 50 to prevent the mounting bracket 50 from continuing to move towards the end wall of the mounting cavity 301 in the insertion direction. Figure 3 As shown, the limiting structure 70 creates a spring space between the micro switch 40 and the end wall of the mounting cavity 301 to accommodate the swing arm 42. Within the spring space, the swing arm 42 swings between the initial position and the trigger position.

[0035] The food processing machine provided by this utility model, on the one hand, provides clear guidance for the installation process of the mounting bracket 50 by setting guide ribs 303 in the mounting cavity 301 and forming a precise fit with the guide groove 501 of the mounting bracket 50, thus achieving fast and accurate installation. At the same time, after installation, the guide ribs 303 and the guide groove 501 form an axial limit, and the support part 302 in the mounting cavity 301 provides stable support for the bottom of the mounting bracket 50. Combined with the positioning design of the micro switch 40 above the mounting bracket 50, it ensures that the relative position of the micro switch 40 in the mounting cavity 301 is accurate and the positioning is reliable, and it can effectively resist vibration and avoid displacement during use. On the other hand, the limiting structure on the side of the mounting cavity 301 near the cup body 10 abuts against the mounting bracket 50, and the limiting structure forms an installation positioning reference for the micro switch 40, accurately controlling the installation depth of the micro switch 40, and realizing precise control of the distance between the swing arm 42 and the cup lid 20. This design avoids the problem of excessive insertion and excessive force during assembly, which could lead to an insufficient distance between the swing arm 42 and the cup lid 20. It also prevents the swing arm 42 from being continuously compressed. The limiting structure creates a rebound space between the micro switch 40 and the end wall of the mounting cavity 301, providing sufficient room for the swing arm 42 to swing between the initial and triggered positions. This prevents the swing arm 42 from getting stuck due to limited space. At the same time, it avoids the safety hazard of the opening motor failing to shut off due to the swing arm not being able to rebound fully and continuously triggering the micro switch. This ensures smooth and accurate triggering action. Combined with the limiting of the guide rib 303, the guide groove 501, and the limiting of the support part 302 against the mounting bracket 50, it effectively reduces problems such as false triggering and failure to trigger the micro switch 40, improves the stability and reliability of the micro switch 40, and enhances the safety of the food processing machine.

[0036] It should be noted that the trigger position of the swing arm 42 is the position where the swing arm 42 triggers the micro switch to conduct. Specifically, the micro switch body is provided with contacts. After the swing arm 42 is driven by magnetic force, the contacts are pressed to realize the conduction of the micro switch and the motor is powered on. The initial position of the swing arm 42 is the position where the swing arm 42 rebounds to the position where the micro switch is disconnected when it is not subjected to the magnetic force of the cup lid. That is, the position where the swing arm 42 is separated from the contacts on the micro switch body and is not under force. At this time, the motor is de-energized.

[0037] like Figure 2 , 3As shown in Figure 4, in a preferred embodiment, the magnetic drive cooperation between the cup lid and the micro switch is specifically as follows: the cup lid 20 is provided with a first magnet 61, and the free end of the swing arm 42 is provided with a second magnet 62. The first magnet 61 and the second magnet 62 are engaged in a repulsive cooperation, so that after the cup lid 20 is closed, the first magnet 61 approaches the second magnet, causing the second magnet 62 to drive the swing arm 42 to swing to the trigger position to trigger the micro switch 40 and power on the motor; after the cup lid 20 is opened, the swing arm 42 elastically returns to the initial position and the motor is de-energized.

[0038] like Figure 6 , 7 As shown, in a preferred embodiment, the support portion 302 includes a first support rib 3021 and a second support rib 3022. The first support rib 3021 is higher than the second support rib 3022 to tilt the mounting bracket 50. The micro switch 40 tilts with the mounting bracket 50 and extends upwardly from the connecting end of the swing arm 42 toward the free end. Preferably, the lower side of the mounting bracket 50 abuts against the cavity sidewall of the mounting cavity 301, and the higher side of the mounting bracket 50 abuts against a limiting rib on another cavity sidewall of the mounting cavity 301. Preferably, the limiting rib and the guide rib 303 can be integrated; however, in practice, the limiting rib and the guide rib 303 can be set independently.

[0039] The support portion 302 includes a first support rib 3021 and a second support rib 3022, providing multi-point support for the mounting bracket 50 and improving its stability. Simultaneously, the varying heights of the first and second support ribs 3021 and 3022 allow the mounting bracket 50 to be tilted at a preset angle, utilizing the diagonal space of the mounting cavity 301 to meet the assembly requirements of the mounting bracket 50. This space-saving and compact design contributes to the miniaturization of the handle 30. Furthermore, the micro switch 40 extends upwards from the connecting end of the swing arm 42 towards its free end, raising the free end of the swing arm 42 and making it easier to approach the cup lid 20. This facilitates effective triggering between the cup lid 20 and the micro switch 40, ensuring sensitive and reliable triggering.

[0040] like Figure 4 , 5 As shown in Figures 6 and 7, more preferably, the mounting bracket 50 includes a support wall 51 and a surrounding wall 52 extending upward from the edge of the support wall 51, and a guide groove 501 is provided on the outer surface of the surrounding wall 52.

[0041] The lower side of the mounting bracket 50 abuts against the sidewall of the mounting cavity 301, while the higher side abuts against a limiting rib on the other sidewall of the mounting cavity 301. This ensures reliable positioning of the mounting bracket 50 on both sides, guaranteeing accurate positioning and reliable triggering of the micro switch 40. By utilizing the tilted micro switch 40, with its lower side abutting against the sidewall of the mounting cavity 301 and its higher side abutting against the limiting rib, friction during installation is reduced, enabling smooth and rapid installation.

[0042] The enclosure 52 provides lateral restraint for the micro switch 40, improving the positioning stability between the micro switch 40 and the mounting bracket 50 and preventing the micro switch 40 from shifting relative to the mounting bracket 50. The enclosure 52 also provides more installation space, allowing the guide groove 501 to be placed on the enclosure 52, achieving rational utilization of the structure. It also facilitates the guidance during the installation of the mounting bracket 50, ensuring accurate installation of the mounting bracket 50 and the micro switch 40, smooth assembly, and more reliable triggering of the micro switch 40.

[0043] The present invention is not limited to the above-described embodiment in terms of the position of the guide groove and guide rib. In another preferred embodiment, the guide groove 501 is located on the bottom surface of the mounting bracket 50, and the guide rib 303 is disposed on the support portion 302. This combines guidance and support / limiting. While supporting the mounting bracket 50, the guide rib 303 on the surface of the support portion 302 directly matches the guide groove 501 on the bottom surface of the bracket, simplifying the overall structure, avoiding the need for additional guide grooves 501 in other locations, and ensuring the guiding action point is close to the support surface, enhancing stability during assembly, preventing the mounting bracket 50 from swaying during installation, and ensuring reliable limiting.

[0044] This utility model does not specifically limit the limiting structure, such as Figure 7 As shown, in a preferred embodiment, the limiting structure 70 includes a first limiting structure. The first limiting structure has a limiting boss 71 located between the end wall of the mounting cavity 301 and the mounting bracket 50. The limiting boss 71 is offset from the swing arm 42 and abuts against the end face of the mounting bracket 50 facing the cup body 10. Specifically, the limiting boss 71 is offset below the swing arm 42 and abuts against the end face of the support wall 51 of the mounting bracket 50; or, the limiting boss 71 is offset on the lateral side of the swing arm 42 and abuts against the end face of the surrounding wall 52 of the mounting bracket 50. More preferably, as shown... Figure 7 As shown, the support part 302 is a support rib, and the limiting boss 71 is connected to the support rib as a whole.

[0045] The limiting structure employs a limiting boss located between the end wall of the mounting cavity 301 and the mounting bracket 50. This boss directly and precisely abuts against the end face of the mounting bracket 50, preventing over-insertion of the mounting bracket 50 and achieving precise control over the distance between the swing arm 42 and the cup lid 20. This makes the triggering of the micro switch 40 more reliable. The limiting boss is misaligned with the swing arm 42, which neither interferes with the swing of the swing arm 42 in the rebound space nor prevents the limiting boss from directly limiting the mounting bracket 50 within this space. The structure is compact and simple. Connecting the limiting boss and the support rib as a single unit achieves structural integration, simplifies the arrangement of the limiting ribs within the mounting cavity 301, saves space, and achieves reliable limiting of the micro switch 40 within the narrow installation space of the handle 30.

[0046] like Figure 7 As shown, the limiting structure 70 also includes a second limiting structure, which is a limiting post 72 protruding from the end wall of the mounting cavity 301. Figure 8 , 9 As shown, the mounting bracket 50 has a downwardly extending extension wall 53, which abuts against the limiting post 72. Figure 1-3 As shown, more preferably, the limiting post 72 is a stud, and the extension wall 53 is provided with a through hole 531 for the screw 80 to pass through. The screw 80 and the stud clamp the extension wall 53 of the mounting bracket 50.

[0047] The mounting bracket 50 features a downward-extending extension wall. This extension wall abuts against a limiting post on the end wall of the mounting cavity 301, preventing the mounting bracket 50 from being over-inserted. The structure is simple. The limiting post is a stud, and screws pass through holes in the extension wall to lock it in place. This strengthens the fixation between the mounting bracket 50 and the mounting cavity 301, preventing the mounting bracket 50 from loosening and ensuring reliable and accurate positioning and triggering of the micro switch 40.

[0048] Of course, it is understood that in other preferred embodiments of this invention, the limiting structure may be only one of the first limiting structure and the second limiting structure described above.

[0049] In addition, the aforementioned limiting boss 71 can protrude from the end wall of the mounting cavity 301 and be separately disposed from the support part 302.

[0050] In other preferred embodiments, the handle 30 includes a handle bracket 31 fixed to the cup body 10 and a handle cover 32 that is fastened to the handle bracket 31 to form a mounting cavity 301. A limiting structure 70 is disposed on the handle bracket 31, and the handle cover 32 and the limiting structure clamp the mounting bracket 50.

[0051] The handle 30 includes a handle bracket 31 and a handle cover 32, which together form a mounting cavity 301 to facilitate the installation of the mounting bracket 50 and the micro switch 40. After installation, the handle cover 32 hides the two components to prevent them from being exposed.
