Description

Technical Field

[0001] This utility model relates to a vegetable cutter with a protective device. Background Technology

[0002] Existing household or commercial vegetable cutters generally use motors to drive the blade disc for cutting. However, during use, the blade disc may still operate if the feeding device is not installed correctly or the pressure bar is not in a safe position, posing a high safety hazard and easily causing accidental injury. Traditional structures usually rely on mechanical latches or a single switch for safety control, which is not safe and reliable enough. Utility Model Content

[0003] The purpose of this invention is to provide a vegetable cutter with a protective device that effectively prevents accidental start-up and improves operational safety.

[0004] The purpose of this utility model is achieved as follows:

[0005] A vegetable cutter with a protective device includes a feeding device, a cutting disc, a machine body, a protective device, and a circuit board. The machine body includes a housing and a drive device. The housing is provided with a cutting chamber and a discharge port. The cutting chamber and the discharge port are connected. The drive device is disposed inside the housing. The cutting disc is detachably disposed inside the cutting chamber and connected to the drive device. The drive device drives the cutting disc to rotate.

[0006] The feeding device includes a housing and a pressing assembly. The pressing assembly includes a pressing rod, a sliding rod, and a slider. The housing has a first feed inlet. The sliding rod is rotatably mounted on the housing, and the slider is slidably mounted on the sliding rod. The slider and the pressing rod are connected.

[0007] The protection device includes a first switch assembly and a second switch assembly. A first contact block is provided at the bottom of the slide bar. A through opening is provided in the housing corresponding to the position of the first contact block. A second contact block is provided in the housing.

[0008] The circuit board is disposed inside the machine body, the first switch assembly and the second switch assembly are disposed on the machine housing, and the first switch assembly, the second switch assembly and the driving device are electrically connected to the circuit board respectively;

[0009] The housing is detachably mounted on the machine housing. The first feed inlet is connected to the cutting chamber. At the same time, the second touch block presses the second switch assembly to activate the second switch assembly.

[0010] The slide bar rotates, causing the pressure bar to face the first feed port, and the first contact block presses the first switch assembly through the through hole to activate the first switch assembly;

[0011] When both the first and second switching components are started, the first and second switching components send signals to the circuit board, and the circuit board starts the driving device.

[0012] The slider slides along the slide bar, and the slider drives the pressure bar to enter or leave the first feed port.

[0013] By setting up a first switch assembly and a second switch assembly, dual detection of the feeding device's installation status and the pressure rod's working status is achieved. The circuit board only starts the drive device when both sets of switches are triggered, thereby effectively preventing accidental motor start-up when the feeding device is not installed or the pressure rod is not in a safe position, thus improving operational safety. At the same time, through the cooperation of the slide bar and the slider, the pressure rod can rotate and slide, making operation flexible, feeding smooth, and improving ease of use and cutting efficiency.

[0014] The objective of this utility model can also be achieved by the following technical measures:

[0015] Furthermore, it also includes a first pin and a second pin, the housing is provided with a pin seat, the pin seat has an upper connecting cavity and a lower connecting cavity, and the pin seat is provided with a second contact block;

[0016] The bottom of the slide bar is provided with a first pin part, the first pin part is provided with a first contact block, the first pin part is placed in the upper connecting cavity, the pin seat has a through opening corresponding to the position of the first contact block, the first pin passes through the pin seat and the first pin part, and the slide bar rotates around the first pin as the rotation center.

[0017] The housing is provided with a second pin portion, which is placed in the lower connecting cavity. The second pin passes through the pin seat and the second pin portion to connect the feeding device and the housing. The feeding device rotates with the second pin portion as the rotation center.

[0018] By setting a first pin and a second pin, a detachable pin-type connection is formed between the slide bar, the feeding device and the machine housing. This not only facilitates the assembly and disassembly of the feeding device and improves the convenience of maintenance and cleaning, but also allows the slide bar and the feeding device to rotate flexibly within a certain angle range by using the pin as a rotation center. Combined with the limit structure, this makes the use safer and more reliable.

[0019] Furthermore, the protective device also includes a housing, which is disposed on the side wall of the housing. The first switch assembly and the second switch assembly are disposed in the inner cavity of the housing. The housing is provided with a second plug portion. The housing has a first socket corresponding to the position of the first push rod and a second socket corresponding to the position of the second push rod.

[0020] By setting an outer shell on the side wall of the casing, the first and second switch assemblies are placed in a closed cavity, which can effectively prevent dust or moisture from entering, protect electrical components from contamination and damage, and improve the electrical safety and protection level of the whole machine.

[0021] Furthermore, it also includes a booster plate, which is placed inside the through-hole. The first contact block contacts the booster plate, and the booster plate moves down to press the first switch assembly, thereby activating the first switch assembly.

[0022] By setting a booster plate inside the through-hole, when the slide bar rotates to a vertical position, the first contact block pushes the booster plate downward, thereby indirectly pressing the first switch assembly, making the start-up detection process smoother and more reliable.

[0023] Furthermore, the first pin portion is provided with a limiting stop plate, which restricts the rotation angle of the slide rod when it abuts against the pin seat.

[0024] Setting a limit stop plate can limit the angle when the slide bar rotates, preventing excessive rotation of the slide bar from causing structural damage or misalignment of the pressure bar, ensuring that the feeding action is carried out within a safe range, thereby further improving the safety and stability of equipment operation.

[0025] Furthermore, it also includes a lock with a lock groove. The lock is rotatably mounted on the housing. The housing is equipped with a locking rod. Rotating the lock will lock the feeding device and the machine body when the locking rod enters the lock groove, and unlock the feeding device and the machine body when the locking rod leaves the lock groove.

[0026] By setting up a locking structure, the feeding device can be mechanically locked after it is installed in place, preventing the feeding device from becoming loose due to vibration or misoperation during use, thus improving the overall connection strength and safety of the machine. At the same time, the lock can be quickly locked and unlocked, facilitating tool replacement and cleaning maintenance.

[0027] Furthermore, it also includes a pusher component, which is disposed inside the cutting chamber and located below the blade disc. The pusher component is connected to a drive device, which drives the pusher component to rotate.

[0028] By setting a pusher component below the cutter head and connecting it to the drive device, the pusher component rotates synchronously during the cutting process of the cutter head, effectively assisting the food to be discharged from the outlet, avoiding clogging, and improving cutting efficiency and smooth discharge.

[0029] Furthermore, it also includes a dicing disc, which is disposed inside the cutting cavity and located below the blade, and the dicing disc is spaced apart with dicing through holes.

[0030] By adding a dicing disc inside the cutting chamber and using it in conjunction with the blade plate, the dicing function can be further enhanced on the basis of slicing, giving the vegetable cutter multiple cutting modes to meet the diverse needs of users and improve the practicality and added value of the product.

[0031] The beneficial effects of this utility model are as follows:

[0032] This invention forms a dual safety protection circuit by setting a first switch assembly and a second switch assembly. The drive device can only be started when the feeding device is correctly installed and the pressure rod is in a safe working position, eliminating the risk of accidental start and significantly improving operational safety. It is especially suitable for homes and catering establishments.

[0033] This utility model, through the cooperation of the first pin, the second pin and the lock, enables the feeding device to form a quick and detachable connection with the machine body. Users can easily complete the installation, disassembly and cleaning operations, making maintenance convenient. The design of the limit baffle ensures that the movement angle is controlled and improves the service life of the whole machine.

[0034] This invention features a material pressing component structure that makes feeding smooth and effortless, a flexible triggering method for the pusher plate and switch that reduces mechanical impact, and a pusher component that further improves output efficiency, ensures smooth continuous cutting, and provides a better user experience.

[0035] This invention features a replaceable design for accessories such as a dicing plate, allowing the device to perform multiple processing modes, including slicing, shredding, and dicing, under the same drive system. It is feature-rich and adaptable to different ingredients and cooking needs. Attached Figure Description

[0107] How to use a vegetable cutter:

[0108] In use, the user first rotates the feeding device 1 to open the cutting chamber 33, and then changes the corresponding blade 2 or adds a dicing plate 80 according to the needs of shredding, slicing, or dicing. Then, depending on the type of food, the user puts the food into the first feeding port 111 or the second feeding port 412; by rotating the slide rod 42, the pressing plate 44 enters or leaves the first feeding port 111, and by sliding the pressing rod 41, the user adjusts the depth of the pressing plate 44, pushing the food into the cutting chamber 33; if feeding through the second feeding port 412, the user can press the pressing rod 45 to push the food into the cutting chamber 33.

[0109] Subsequently, the drive unit 32 (motor) drives the blade and the pusher 30 to rotate synchronously via the reducer 7, realizing vegetable cutting and automatic dispensing. The user can adjust the motor speed through the speed controller 321 to control the cutting speed to suit different ingredients; finally, the start and stop of the whole machine is controlled by the power switch 323.

[0110] Multiple ingredient delivery methods:

[0111] The first feeding port 111 is a large crescent-shaped feeding port, suitable for placing larger pieces or whole vegetables, fruits and other ingredients. Users can directly push the ingredients into the cutting chamber 33 through the pressing plate 44 to achieve fast and efficient cutting.

[0112] The second feeding port 412 is a small-sized feeding port, suitable for placing small pieces or long and thin ingredients. The ingredients are fed into the cutting chamber 33 by the pressing rod 45, ensuring stable feeding and preventing slippage.

[0113] The two feed inlets work together to meet the processing needs of different ingredients, which not only improves the flexibility of use, but also ensures smooth feeding and cutting accuracy, making it much easier for users to shred, slice or dice the ingredients according to their type.

[0114] Labor-saving and safe feeding function:

[0115] This vegetable cutter uses a lever-based, labor-saving feeding structure. After the user lifts the pressing rod 41 away from the first feeding port 111, the user can rotate the pressing rod 41 to drive the sliding rod 42 to rotate. The lever action easily moves the pressing component 4, making the first feeding port 111 fully exposed, which makes it easy to smoothly feed in larger pieces or whole vegetables.

[0116] Subsequently, the user rotates the pressing rod 41 in the opposite direction to reset the sliding rod 42, aligning the pressing rod 41 with the first feed port 111, and slides the pressing rod 41. Under the action of the slider 43 and the sliding rod 42, the pressing action is smooth and stable, making it easy to feed large pieces or whole vegetables.

[0117] When processing small or long ingredients, users can directly pull out the pressing rod 45, put the ingredients into the second feed port 412, and then insert the pressing rod 45 into the feeding channel 411 to smoothly push the ingredients into the cutting chamber 33, which meets the needs of various ingredients and makes the operation more flexible and convenient.

[0118] Meanwhile, when the slide bar 42 rotates to open the first feed port 111, the first micro switch 613 is closed and the drive device 32 is de-energized to ensure the safety of the user's feeding process; when the slide bar 42 rotates to a vertical state and the pressing rod 41 is aligned with the first feed port 111, the first micro switch 613 is activated and the drive device 32 is powered on to cut vegetables, which is both labor-saving and safe, and highly practical.

[0119] The vegetable cutter has dual protection features:

[0120] When the feeding device 1 is connected to the housing 31, the second contact block 54 passes through the second insertion port 632 and presses the second push rod 621, causing the second protrusion 6211 to touch the second micro switch 623, thus activating the second micro switch 623. At the same time, when the user rotates the slide bar 42 to a vertical state (the pressing plate 44 enters the first feed port 111), the first contact block 4211 pushes the pusher plate 70 through the through port 53. The pusher plate 70 presses the first push rod 611, causing the first protrusion 6111 to touch the first micro switch 613, thus activating the first micro switch 613.

[0121] The circuit board receives a signal to activate the drive device 32 and enable power operation only when both the first microswitch 613 and the second microswitch 623 are activated. This prevents the equipment from operating if the feeding device 1 is not installed correctly or if the pressure plate 44 does not enter the feed inlet, effectively preventing accidental activation and ensuring safe operation.

[0122] The heat dissipation function of the vegetable cutter:

[0123] When the vegetable cutter is working, the drive unit 32 (motor) synchronously drives the cooling fan 8 to rotate. External cold air enters the inner cavity of the housing 31 through the heat dissipation hole 60 at the bottom of the housing 31. After effectively cooling the motor through the heat dissipation vent 50, the air flows along the heat dissipation cavity 81 and the heat dissipation channel 82 and is discharged from the heat dissipation outlet 821. The heat dissipation channel 82 is equipped with partition plates 822 and guide ribs 823 to optimize the airflow path, which not only improves the heat dissipation efficiency but also reduces airflow noise, achieving efficient and quiet heat dissipation and ensuring stable operation of the equipment for a long time.

[0124] The efficient transmission function of the vegetable cutter:

[0125] When the drive unit 32 (motor) starts, the first sun gear 76 on its rotating shaft drives the first planetary gear 722 in the first-stage reduction unit 72 to rotate. The first planetary gear 722 meshes with the first gear ring 721 and drives the first planetary carrier 723 to rotate, thereby driving the second sun gear 724 to rotate. The second sun gear 724 further drives the second planetary gear 731 in the second-stage reduction unit 73 to rotate. The second planetary gear 731 meshes with the second gear ring 75 and drives the second planetary carrier 732 to rotate, ultimately driving the turntable 74 and the transmission rod 77 to output high torque power after reduction, realizing smooth drive of the blade. The entire reduction process is completed through multi-stage planetary gear transmission, and each stage of gear adopts a helical tooth structure, so that the tooth surfaces gradually contact during meshing, the force is smooth, the operating noise is low, and the energy transfer is more efficient, thus achieving the efficient, stable, and quiet transmission effect of the vegetable cutter.

[0126] Easy-to-clean features of the vegetable cutter:

[0127] When the user rotates the lock 40, the locking rod 312 leaves the locking groove 401, thus unlocking the feeding device 1 and the machine body 3. Then, the user only needs to pull out the second pin 20 to quickly separate the feeding device 1 from the machine body 3. At this time, the second push rod 621 is reset under the action of the second spring 622, and the second protrusion 6211 moves away from the second micro switch 623, causing the second micro switch 623 to close. Only then does the circuit board receive the signal to shut down the drive device 32, which facilitates the replacement of the blade and the cleaning of the inside of the cutting chamber 33.

[0128] Next, the user can also pull out the first pin 10 to separate the pressing component 4 from the housing 11, so that the pressing rod 41, pressing plate 44 and other components can be cleaned separately. The modular disassembly and assembly method of the whole machine makes the cleaning process simpler and more thorough, avoids food residue, and ensures hygiene and convenient maintenance.
