Description

Technical Field

[0001] This invention relates to a processing tool based on a pressure feeder, and more specifically, to a residual material removal structure and a roller-type vegetable cutter. Background Technology

[0002] Processing tools based on pressure feeders utilize the downward pressure of the feeder to bring material into contact with the processing actuator for processing. A typical example is a drum-type vegetable cutter. These tools use a feeding cylinder to hold the material, and the feeder pushes the material forward. As the material in the feeding cylinder decreases, the feeder gradually moves downward. To prevent the feeder from contacting the processing actuator (e.g., the blade of a drum-type vegetable cutter), the lowest point of the feeder's movement is often limited, leaving a gap between them. Because of this gap, when the thickness of the remaining material is less than or equal to the gap height, the feeder cannot apply force towards the processing actuator. Therefore, the remaining material cannot be further processed by the actuator, resulting in residue. This residue usually gets stuck at the bottom of the feeding cylinder and cannot be discharged. It typically requires disassembling the processing actuator (e.g., the blade of a drum-type vegetable cutter) to remove it, adding unnecessary trouble.

[0003] In addition, the blades of existing drum-type vegetable cutters need to be disassembled for cleaning or replacement frequently. However, the existing blade disassembly and assembly structure is relatively complex and difficult to operate. In particular, after the blades are installed inside the cutting tube, the entire blade is located inside the cutting tube, and there is no suitable position to pull out the blades during disassembly, making the disassembly of the blades relatively troublesome. Furthermore, the blades may come into contact with the blades during disassembly, which also poses certain safety hazards.

[0004] Furthermore, the electrification of existing drum vegetable cutters is gradually becoming a trend. Motor-driven drum vegetable cutters are easier and less strenuous to use, making them popular with consumers. Currently, electric drum vegetable cutters exist, but most are fixed to countertops. Handheld electric drum vegetable cutters are not yet available on the market. A handheld cutter allows for direct placement of chopped ingredients into the desired container, enabling "on-demand" operation. This not only reduces intermediate loading steps but also allows for flexible control of the relative position between the cutter's outlet and the container, making it more convenient and flexible to use. Therefore, designing a handheld electric drum vegetable cutter perfectly meets current needs. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve

[0006] One objective of this invention is to solve the problem of difficult discharge of residual material in processing tools based on pressure feeders, such as drum-type vegetable cutters, and to provide a residual material removal structure. By using the technical solution of this invention, a removal port that communicates with the bottom gap of the pressure feeder is provided on the outer shell, which can conveniently discharge the last residual material. The design is ingenious, the structure is compact, and it is flexible and convenient to use.

[0007] Another objective of this invention is to provide a drum-type vegetable cutter with a conveniently detachable blade barrel. By having a pull ring at the front of the blade barrel body, the blade barrel can be easily removed using the pull ring. The blade barrel removal operation is simple and convenient, and does not require direct contact with the blade barrel, making the operation safer. In addition, the pull ring can be folded up and unfolded on the blade barrel, and the folding up does not affect the feeding of food.

[0008] Another objective of this invention is to provide a handheld electric roller vegetable cutter that solves the problem of poor flexibility in the use of existing fixed roller vegetable cutters. By using a compact electric drive mechanism as the grip handle and power source, the relative position between the cutter's outlet and the container can be flexibly controlled during use, making it more flexible and convenient to use. It can also reduce intermediate loading steps and achieve "cut and use immediately".

[0009] 2. Technical Solution

[0010] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0012] An outer casing, wherein a feeding cylinder is provided on the outer casing; and,

[0013] A feeder, the feeder being insertable into the feeding cylinder; and,

[0014] The processing actuator is located inside the housing and corresponds to the position of the feeding cylinder. After the pressure device is pressed into the bottom of the feeding cylinder, there is a gap between the bottom of the pressure device and the processing actuator.

[0015] The outer casing has a discharge port that communicates with the aforementioned gap and is used to discharge residual material from the gap.

[0016] Furthermore, the processing actuator performs reciprocating linear or rotary motion within the housing, and the position of the rejection outlet on the housing is opposite to the tangent direction of the linear or rotary motion direction of the processing actuator.

[0017] Furthermore, the feeding cylinder has a processing start side and a processing end side in its processing movement relative to the processing actuator, and the rejection outlet is located on the outer casing near the processing end side of the feeding cylinder.

[0018] Furthermore, the ejector port is located near the root of the feeding cylinder.

[0019] Furthermore, the height h of the rejection outlet is greater than the thickness d of the gap, and when the pressure device is pressed into the bottom of the feeding cylinder, the side corner of the bottom of the pressure device near the rejection outlet is lower than the upper side wall of the rejection outlet.

[0020] Furthermore, the lower sidewall of the ejection port is provided with ejection ribs located inside the outer casing.

[0021] Furthermore, the width w1 of the ejection port is greater than or equal to the width w2 of the root of the feeding cylinder.

[0022] The present invention provides a drum-type vegetable cutter having the above-mentioned residual material removal structure, wherein the outer shell is the cutting cylinder of the drum-type vegetable cutter, the processing actuator is the blade cylinder of the drum-type vegetable cutter, and the blade cylinder rotates inside the cutting cylinder.

[0023] Furthermore, the cutter barrel includes a cutter barrel body, the side wall of which is provided with a cutting blade, and the tail of the cutter barrel body has a transmission connection structure connected to the drive mechanism.

[0024] Furthermore, the bottom of the pressure device is a concave arc shape that matches the shape of the outer wall of the blade cylinder body, and the upper part of the pressure device has a limiting cap that matches the upper end of the feeding cylinder; after the pressure device is pressed into the bottom of the feeding cylinder, the food remaining in the gap is discharged from the dispensing port on the cutting cylinder as the blade cylinder rotates.

[0025] Furthermore, the front of the cutter barrel body has a pull ring, which has a folded position and an unfolded position at the front of the cutter barrel body, and the pull ring can rotate and switch between the folded position and the unfolded position.

[0026] Furthermore, the pull ring is semi-circular, and both ends of the pull ring have coaxial rotating parts. The pull ring is rotatably mounted on the blade barrel body through the rotating parts at both ends, and the axis of the rotating part of the pull ring passes through the center of the circle of the corresponding cross section at the front of the blade barrel body. The pull ring can rotate around the rotating part to switch between a folded position and an unfolded position. After the pull ring is folded, it fits against the front end face of the blade barrel body.

[0027] Furthermore, the front end face of the blade barrel body has a pull ring groove for accommodating a pull ring. The pull ring is located in the pull ring groove after being folded. The pull ring groove also has a groove to facilitate unfolding the pull ring.

[0028] Furthermore, the drive mechanism has a transmission connector that cooperates with the transmission connection structure at the tail of the blade barrel body. The transmission connector is provided with a spiral transmission rib. The tail of the blade barrel body is coaxially provided with a transmission shaft hole. The inner side of the transmission shaft hole is provided with a transmission protrusion that is spirally engaged with the aforementioned spiral transmission rib. The tightening direction of the spiral transmission rib and the transmission shaft hole is consistent with the cutting rotation direction of the blade barrel. The front of the cutting barrel is also provided with a flexible stop for axially limiting the blade barrel.

[0029] Furthermore, the inner side of the tail of the main body of the cutter barrel is also provided with a blind cap for sealing the drive shaft hole.

[0030] Furthermore, the drive mechanism is an electric drive mechanism used as a grip handle.

[0031] Furthermore, the outer wall of the feeding cylinder is also provided with several raised ribs.

[0032] Furthermore, the drive mechanism includes a front housing, a rear housing, a transmission connector, a reducer, and a motor. The reducer and the motor are connected to form an integrated geared motor. The geared motor is fixedly connected to the rear housing by screws, and the front housing is fixedly connected to the geared motor by screws. The front housing and the rear housing are joined together along the axial direction of the geared motor to form a cavity for accommodating the geared motor. The output shaft of the geared motor is coaxially connected to the transmission connector located outside the front housing.

[0033] Furthermore, the rear housing has a rear housing screw hole, and the outer shell of the reducer has a front housing screw hole and a through hole. The reduction motor is fixedly connected to the rear housing by a first screw that passes through the through hole and is screwed into the rear housing screw hole. The front housing has a front housing connection hole, and the front housing is fixedly connected to the reduction motor by a second screw that passes through the front housing connection hole and is screwed into the front housing screw hole.

[0034] Furthermore, the front end face of the drive mechanism is provided with a plug-in part and a rotating buckle, and the tail end of the cutting tube is provided with a plug-in hole and a rotating slot. The outer diameter of the plug-in part is adapted to the inner diameter of the plug-in hole, so that the plug-in part can be inserted into the plug-in hole and rotate relative to the axial direction. The rotating buckle is located on the outside of the plug-in part, and the rotating slot is located on the outside of the plug-in hole. The rotating buckle can be inserted into and rotated into the rotating slot.

[0035] Furthermore, the drive mechanism is shaped like a straight handle or a triangular handle. When the drive mechanism is straight, the main body of the drive mechanism is used as a gripping part; when the drive mechanism is triangular, the drive mechanism has a holding part, one end of which is connected to the tail of the main body of the drive mechanism, and the other end of which is connected to the front of the main body of the drive mechanism through a vertical part.

[0036] Furthermore, when the drive mechanism is triangular in shape, the rear sidewall of the feeding cylinder is in contact with the front sidewall of the vertical part of the gripping part, the upper part of the rear sidewall of the feeding cylinder has an upper slot, and the upper part of the front sidewall of the vertical part has an upper buckle that cooperates with the aforementioned upper slot.

[0037] 3. Beneficial effects

[0038] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages:

[0039] (1) A residual material removal structure of the present invention includes an outer shell, a pressure device, and a processing execution component. The processing execution component is disposed in the outer shell and corresponds to the position of the feeding cylinder on the outer shell. After the pressure device is pressed into the bottom of the feeding cylinder, there is a gap between the bottom of the pressure device and the processing execution component. The outer shell has a removal port that communicates with the gap and is used to discharge the residual material in the gap. The removal port can conveniently discharge the last residual material. The design is ingenious, the structure is compact, and the use is flexible and convenient. It effectively solves the problem that residual material is difficult to discharge in processing tools based on pressure devices, such as roller-type vegetable cutters.

[0040] (2) A residual material removal structure of the present invention can be used in a processing tool for processing actuators to perform reciprocating linear motion or rotational motion, and the position of the removal outlet on the outer shell is opposite to the tangent direction of the linear motion direction or the rotational motion direction of the processing actuators, so that the residual material can be pushed out from the removal outlet by the motion of the processing actuators, making it more convenient to remove the residual material.

[0041] (3) A residual material removal structure of the present invention has a removal outlet on the outer shell near the processing end side of the feeding cylinder, so that the residual material can be directly discharged in the processing direction without additional reverse operation, which further improves the convenience of residual material discharge.

[0042] (4) A residual material removal structure of the present invention has a removal outlet close to the root of the feeding cylinder, so that the remaining residual material in the feeding cylinder is closer to the removal outlet, which facilitates the discharge of the material and reduces the situation where residual material enters the gap between the processing actuator and the outer shell and gets stuck.

[0043] (5) In a residual material rejection structure of the present invention, the height h of the rejection outlet is greater than the thickness d of the gap. When the pressure device is pressed into the bottom of the feeding cylinder, the side corner of the bottom of the pressure device near the rejection outlet is lower than the upper side wall of the rejection outlet. This can prevent the residual material from being blocked by the upper side wall of the rejection outlet and thus prevent it from being discharged, making the discharge of the residual material smoother. Furthermore, the lower side wall of the rejection outlet is provided with a rejection rib located inside the outer shell. The rejection rib can play a guiding role, so that the head of the residual material is lifted under the action of the rejection rib and guided towards the rejection outlet, which further facilitates the rapid and stable discharge of the residual material.

[0044] (6) By applying the above-mentioned residual material removal structure to the drum-type vegetable cutter, after the presser is pressed into the bottom of the feeding cylinder, the food remaining in the gap is discharged from the removal port on the cutting cylinder as the blade cylinder rotates. This solves the problem that the last piece of food in the existing drum-type vegetable cutter is left in the cutting cylinder and cannot be discharged, further improving the practicality and convenience of the drum-type vegetable cutter.

[0045] (7) Compared with existing drum-type vegetable cutters, the drum-type vegetable cutter of the present invention also has the following advantages:

[0046] a. With a pull ring at the front of the blade barrel body, the blade barrel can be easily disassembled using the pull ring. The blade barrel disassembly operation is simple and convenient, and there is no need to directly contact the blade barrel, making the operation safer. In addition, the pull ring can be folded up and unfolded on the blade barrel, and the folding up does not affect the output of food.

[0047] b. The drive mechanism's transmission connector and the blade cylinder are connected by a spiral interlocking structure. The blade cylinder will not separate from the transmission connector during rotation, ensuring stable and reliable transmission, and the blade cylinder is easy to assemble and disassemble. At the same time, a flexible stop block is used to axially limit the blade cylinder, effectively preventing static slippage without affecting the installation and disassembly of the blade cylinder, thus ensuring the stability of the blade cylinder inside the cutting tube during operation. Furthermore, the end cap set on the inner side of the tail of the blade cylinder body can prevent food from directly contacting the transmission connector, achieving separation of power and food, ensuring food safety and facilitating the cleaning of the cutter.

[0048] c. It features an electric drive mechanism that can also be used as a gripping handle, enabling handheld operation of the drum-type vegetable cutter. This solves the problem of poor flexibility in the use of existing fixed-use drum-type vegetable cutters. Utilizing a compact electric drive mechanism as both a gripping handle and a power source, the relative position between the cutter's outlet and the container can be flexibly controlled during use, making it more flexible and convenient to use. It also reduces intermediate loading steps, achieving "cut and use immediately." Furthermore, the aforementioned electric drive mechanism is compact and comfortable to hold, with a simple installation structure that is easy to assemble. The cutting cylinder and the handheld power handle are connected by a rotating locking structure, making connection and disassembly simple, quick, and the connection secure and stable.

[0049] d. Several ribs are provided on the outer wall of the feeding cylinder. The ribs on the feeding cylinder make it easy to hold and press the feeder with one hand, which can effectively share the weight and pressure borne by the other hand, further improving the ease and flexibility of hand operation of the roller-type vegetable cutter.

[0050] e. The drive mechanism is shaped like a straight handle or a triangular handle. When the drive mechanism is triangular, it has a gripping part. The triangular handle design is novel, and the gripping part is comfortable to hold and operate, making it highly practical. Furthermore, when the drive mechanism is triangular, a snap-fit ​​structure can be used between the feeding cylinder and the drive mechanism to further strengthen the connection and ensure the overall structural strength. The feeding cylinder is not easy to shake during use. Attached Figure Description

Detailed Implementation

[0075] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0076] Figures 1 to 7 The structural principle of the residual material removal structure of the present invention is illustrated using a tool barrel as the machining actuator. This structure aims to solve the problem of difficult discharge of residual material in machining tools based on pressure feeders. (Refer to...) Figures 1 to 7 As shown, a residual material removal structure of the present invention includes:

[0077] The outer casing 1 has a feeding cylinder 1-1 on it, the root of which is connected to the outer casing 1 for feeding the material to be processed through the feeding cylinder 1-1; and,

[0078] The pressure feeder 2 can be inserted into the feeding cylinder 1-1 to apply a pushing force to the material to be processed inside the feeding cylinder 1-1; and,

[0079] The processing actuator 3 is located inside the outer shell 1 and corresponds to the position of the feeding cylinder 1-1. The processing actuator 3 processes the material to be processed in the feeding cylinder 1-1. After the pressure device 2 is pressed into the bottom of the feeding cylinder 1-1, there is a gap g between the bottom of the pressure device 2 and the processing actuator 3. This gap g can ensure that the pressure device 2 does not contact the processing actuator 3.

[0080] Unlike existing technologies, in this invention, the outer shell 1 has a discharge port 1-2 that communicates with the aforementioned gap g and is used to discharge residual material within the gap g. When the material is processed by pressing down with the pressure feeder 2, due to the existence of the gap g, some material will always remain within the gap g and cannot be processed by the processing actuator 3. This residual material can be discharged through the discharge port 1-2. The discharge port 1-2 allows for convenient discharge of the final residual material. This ingenious design, compact structure, and flexible and convenient use effectively solves the problem of difficult discharge of residual material in processing tools based on pressure feeders, such as roller-type vegetable cutters.

[0081] The aforementioned processing actuator 3 can perform reciprocating linear motion or rotational motion within the outer casing 1. Taking a vegetable cutter based on the pressure feeder 2 as an example, common types on the market include roller-type vegetable cutters, flat-plate vegetable cutters with a feeding cylinder (such as those disclosed in patents 202122696747.3 and 202223309220.1), and blade-type vegetable cutters (such as those disclosed in patents 202220682867.X and 202221850782.4). The processing actuator 3 of the roller-type and blade-type vegetable cutters rotates, while the processing actuator 3 of the flat-plate vegetable cutter with a feeding cylinder performs reciprocating linear motion. When the processing actuator 3 performs reciprocating linear motion, it moves back and forth at the bottom of the feeding cylinder 1-1 to process the material; when the processing actuator 3 performs rotational motion, it rotates in one direction to process the material. The position of the ejector outlet 1-2 on the outer shell 1 is opposite to the tangent direction of the linear motion direction or the rotational motion direction of the processing actuator 3. This allows the residual material to be pushed out of the ejector outlet by the motion of the processing actuator 3, making it more convenient to discharge the residual material.

[0082] The aforementioned feeding cylinder 1-1 has a processing start side and a processing end side in its processing movement relative to the processing actuator 3. When the processing actuator 3 moves to process the material inside the feeding cylinder 1-1, the cutting of the material at a certain position of the processing actuator 3 always has a process from the start of cutting to the end of cutting. The so-called "processing start side" is the side of the feeding cylinder 1-1 near the material where cutting begins, and the "processing end side" is the side of the feeding cylinder 1-1 near the material where cutting is completed. In this invention, the ejector 1-2 is located on the outer shell 1 near the processing end side of the feeding cylinder 1-1, which allows residual material to be discharged directly in the processing direction without additional reverse operation, further improving the convenience of residual material discharge. Of course, the feasibility of setting the rejection outlet 1-2 on the processing start side of the feeding cylinder 1-1 is not ruled out. When the processing actuator 3 performs reciprocating linear motion, the retraction action of the processing actuator 3 can be used to carry the last residual material out from the rejection outlet 1-2. When the processing actuator 3 performs rotational motion, the reverse rotation of the processing actuator 3 can be controlled to carry the last residual material out from the rejection outlet 1-2.

[0083] Furthermore, in this invention, the ejector outlet 1-2 is preferably located near the root of the feeding cylinder 1-1, so that the remaining residual material in the feeding cylinder 1-1 is closer to the ejector outlet, facilitating material discharge and reducing the possibility of residual material getting stuck in the gap between the processing actuator 3 and the outer shell 1. To facilitate smooth discharge of residual material, the height h of the ejector outlet 1-2 is greater than the thickness d of the gap g. When the pressure device 2 is pressed into the bottom of the feeding cylinder 1-1, the side corner 2-1 of the bottom of the pressure device 2 near the ejector outlet 1-2 is lower than the upper side wall of the ejector outlet 1-2. This prevents the residual material from being blocked by the upper side wall of the ejector outlet 1-2 and thus makes the discharge of residual material smoother. The lower side wall of the ejector outlet 1-2 is provided with ejector ribs 1-2-1 located inside the outer shell 1. These ejector ribs 1-2-1 act as guides, causing the head of the residual material to be lifted by the ejector ribs 1-2-1 and guided towards the ejector outlet 1-2, further facilitating the rapid and stable discharge of residual material. The width w1 of the ejector outlet 1-2 is greater than or equal to the width w2 of the root of the feeding cylinder 1-1, so that the size of the ejector outlet 1-2 is larger than the size of the residual material, which also facilitates the discharge of the residual material.

[0084] This invention provides a residue removal structure applicable to various processing tools based on a pressure feeder, particularly showing promising application prospects and promotional value in small vegetable cutters based on pressure feeders. To this end, the invention also relates to a drum-type vegetable cutter with the aforementioned residue removal structure. The outer shell 1 is the cutting cylinder of the drum-type vegetable cutter, and the processing actuator 3 is the blade cylinder of the drum-type vegetable cutter, which rotates within the cutting cylinder. By applying the aforementioned residue removal structure to the drum-type vegetable cutter, after the pressure feeder 2 presses the food into the bottom of the feeding cylinder 1-1, the remaining food in the gap is discharged from the removal port on the cutting cylinder as the blade cylinder rotates. This solves the problem of the last piece of food remaining in the cutting cylinder and unable to be discharged in existing drum-type vegetable cutters, further improving the practicality and convenience of the drum-type vegetable cutter.

[0085] To further understand the technical content of the present invention, the following description uses a drum-type vegetable cutter as a specific example to further illustrate the residue removal structure of the present invention, and also provides an improved drum-type vegetable cutter.

[0086] [Example 1]

[0087] Reference Figures 1 to 8 As shown, this embodiment discloses a drum-type vegetable cutter, which includes a housing 1, a pressing device 2, and a processing actuator 3. The housing 1 is the cutting cylinder, and a feeding cylinder 1-1 is provided on the cutting cylinder. The pressing device 2 is adapted to the feeding cylinder 1-1 and can be inserted into the feeding cylinder 1-1 to press down the food inside the feeding cylinder 1-1. The processing actuator 3 is the blade cylinder, which is installed inside the cutting cylinder and can rotate inside the cutting cylinder. The cutting blades 3-2 on the blade cylinder cut the food inside the feeding cylinder 1-1. After the pressing device 2 is pressed into the bottom of the feeding cylinder 1-1, there is a gap g between the bottom of the pressing device 2 and the blade cylinder (e.g., ...). Figure 4 and Figure 5 (As shown). The cutting cylinder has a discharge port 1-2 that communicates with the aforementioned gap g and is used to discharge residual food within the gap g. Specifically, the discharge port 1-2 is positioned on the cutting cylinder opposite to the tangential direction of the blade cylinder's rotation, allowing the movement of the blade cylinder to push residual material out of the discharge port, making the discharge of residual material more convenient. Preferably, the discharge port 1-2 is located on the cutting cylinder near the processing end side of the feeding cylinder 1-1, so that residual food can be directly discharged in the direction of the blade cylinder's rotation without additional reverse operation, further improving the convenience of discharging the last piece of food.

[0088] like Figure 1 and Figure 2 as well as Figures 5 to 7As shown, preferably, the ejector port 1-2 is located near the root of the feeding cylinder 1-1, so that the remaining food residue in the feeding cylinder 1-1 is closer to the ejector port 1-2, facilitating the discharge of food residue and reducing the possibility of food residue getting stuck in the gap between the blade cylinder and the cutting cylinder. Figure 5 and Figure 6 As shown, the height h of the ejector outlet 1-2 is greater than the thickness d of the gap g. When the pressure device 2 is pressed into the bottom of the feeding cylinder 1-1, the side corner 2-1 of the bottom of the pressure device 2 near the ejector outlet 1-2 is lower than the upper side wall of the ejector outlet 1-2. This prevents residual food from being blocked by the upper side wall of the ejector outlet 1-2 and thus makes the discharge of residual food smoother. Furthermore, the lower side wall of the ejector outlet 1-2 is provided with ejector ribs 1-2-1 located inside the cutting cylinder (see reference). Figure 6 and Figure 7 The ejector rib 1-2-1 acts as a guide, lifting the head of the remaining food and guiding it towards the ejector outlet 1-2, further facilitating the rapid and stable discharge of the remaining food. Additionally, the width w1 of the ejector outlet 1-2 is greater than or equal to the width w2 at the base of the feeding cylinder 1-1. Since the size of the added food is smaller than the cross-sectional size of the feeding cylinder 1-1, the width of the ejector outlet 1-2 is greater than the width of the food, making food discharge easier.

[0089] Reference Figure 8 and Figure 9 As shown, this embodiment of a roller-type vegetable cutter includes a blade body 3-1, which can be cylindrical or trumpet-shaped. Cutting blades 3-2 are provided on the side walls of the blade body 3-1. The tail of the blade body 3-1 has a transmission connection structure connected to a drive mechanism 4. The drive mechanism 4 drives the blade body to rotate axially, using the cutting blades 3-2 to cut food. The drive mechanism 4 can be an electric drive mechanism or a hand-cranked drive mechanism. The structure of the cutting blades 3-2 is similar to that of existing technologies, including blade structures for slicing, shredding, and mincing. The cutting blades 3-2 can be directly formed on the blade body 3-1, or they can be detachably mounted on the blade body 3-1. Figure 5 As shown, the bottom of the pressure device 2 is a concave arc shape that matches the shape of the outer wall of the blade cylinder body 3-1. The upper part of the pressure device 2 has a limiting cap 2-2 that cooperates with the upper end of the feeding cylinder 1-1. When the pressure device 2 is pressed down until the limiting cap 2-2 abuts against the upper end of the feeding cylinder 1-1, the pressure device 2 can no longer press down, thus forming a gap g and the remaining food in the gap g. After the pressure device 2 is pressed into the bottom of the feeding cylinder 1-1, the remaining food in the gap g can be discharged from the discharge port 1-2 on the cutting cylinder as the blade cylinder rotates. This solves the problem of the last piece of food remaining in the cutting cylinder and not being discharged in the existing drum-type vegetable cutter, further improving the practicality and convenience of the drum-type vegetable cutter.

[0090] [Example 2]

[0091] Based on Embodiment 1 above, this embodiment further provides a drum-type vegetable cutter with an easily detachable blade barrel. For example... Figures 9 to 13 As shown, in this embodiment, the front of the blade barrel body 3-1 has a pull ring 3-3. The pull ring 3-3 has a folded position and an unfolded position at the front of the blade barrel body 3-1, and the pull ring 3-3 can rotate and switch between the folded position and the unfolded position. When unfolded, the pull ring 3-3 can be used as a lifting handle for the blade barrel. When disassembling the blade barrel, the pull ring 3-3 can be used to easily disassemble the blade barrel. The blade barrel disassembly operation is simple and convenient, and there is no need to directly contact the blade barrel, making the operation safer. In the folded position, the pull ring 3-3 can be folded up. When folded up, it does not affect the food output, making it flexible and convenient to use.

[0092] Figure 10 and Figure 11 A schematic diagram of a cutter barrel structure is shown. Figure 12 and Figure 13 A schematic diagram of another type of cutter barrel is shown. (Refer to...) Figures 10 to 13 As shown, the pull ring 3-3 is preferably semi-circular, with coaxial rotating parts at both ends. The pull ring 3-3 is rotatably mounted on the cutter barrel body 3-1 via these rotating parts, and the axis of the rotating part of the pull ring 3-3 passes through the center of the corresponding cross-sectional circle at the front of the cutter barrel body 3-1. The pull ring 3-3 can rotate around the rotating part to switch between a folded position and an unfolded position. After folding, the pull ring 3-3 fits snugly against the front end face of the cutter barrel body 3-1. This pull ring design allows for free folding and storage on both sides. The folded pull ring 3-3 is more compact and does not affect the rotation of the cutter barrel or the material discharge. Furthermore, as... Figure 10 and Figure 11 As shown, the front end face of the blade barrel body 3-1 has a pull ring groove for accommodating the pull ring 3-3. After folding, the pull ring 3-3 is located in the pull ring groove, further ensuring the compactness of the structure after the pull ring is folded. The pull ring groove also has a recess 3-4 to facilitate the unfolding of the pull ring 3-3, making it easy for fingers to pull the pull ring 3-3 out of the pull ring groove and unfold, thus improving the ease of use of the pull ring.

[0093] To facilitate the installation of the pull ring 3-3, two opposing bosses 3-5 are provided on the front end face of the cutter barrel body 3-1 (e.g., Figure 10 and Figure 11The boss 3-5 has rotating holes, and the rotating parts at both ends of the pull ring 3-3 are respectively installed in the rotating holes of the boss 3-5, making the installation of the pull ring 3-3 simple and convenient. The pull ring 3-3 can be made of bent stainless steel wire. During installation, the pull ring 3-3 can be bent inward to move the rotating parts at both ends inward, and then inserted into the corresponding rotating holes. The elasticity of the pull ring 3-3 ensures that the rotating parts are stably assembled in the corresponding rotating holes. Alternatively, it can be... Figure 12 and Figure 13 As shown, a rotating hole is directly set on the front side wall of the blade body 3-1, and the rotating parts at both ends of the pull ring 3-3 are respectively installed in the corresponding rotating holes. After the pull ring 3-3 is folded, it fits tightly against the inner side wall of the blade body 3-1, which does not affect the discharge of food.

[0094] Furthermore, in this embodiment, the drum-type vegetable cutter has a drive mechanism 4 with a transmission connector 4-3 that cooperates with the transmission connection structure at the tail of the blade body 3-1. The transmission connector 4-3 is provided with a spiral transmission rib 4-3-1 (e.g., Figure 15 As shown), the tail of the cutter barrel body 3-1 is coaxially provided with a drive shaft hole 3-6 (as shown). Figures 10 to 14 As shown, the inner side of the drive shaft hole 3-6 is provided with a drive protrusion 3-6-1 that is helically engaged with the aforementioned helical drive rib 4-3-1. The tightening direction of the helical drive rib 4-3-1 and the drive shaft hole 3-6 is consistent with the cutting rotation direction of the cutter cylinder. The rotation of the drive connector 4-3 drives the cutter cylinder to rotate. Under the helical engagement, the cutter cylinder and the drive connector 4-3 are more firmly connected. The cutter cylinder will not separate from the drive connector 4-3 during rotation, ensuring stable and reliable transmission. Furthermore, the cutter cylinder can be connected or separated from the drive connector 4-3 simply by axial insertion and removal. Combined with the aforementioned pull ring design, the disassembly and assembly of the cutter cylinder is more convenient. To prevent the blade cylinder from separating from the transmission connector 4-3 and sliding out of the cutting cylinder when static (i.e., when the transmission connector 4-3 is not rotating), a flexible stop 1-3 is provided at the front of the cutting cylinder to limit the axial movement of the blade cylinder. This flexible stop 1-3 can be made of soft materials such as silicone, allowing for elastic deformation and bending under force. The flexible stop 1-3 does not affect the installation and disassembly of the blade cylinder and effectively prevents static slippage, ensuring the stability of the blade cylinder within the cutting cylinder during operation. Furthermore, during operation, the blade cylinder is always inclined to move axially towards the transmission connector 4-3; therefore, in this working state, there will be no contact between the blade cylinder and the flexible stop 2-2, preventing obstruction or friction. When it is necessary to replace or disassemble the cleaning cutter cylinder, flip the pull ring 3-3 90° and hold the pull ring 3-3 and rotate it left and right to remove the cutter cylinder. At the same time, the flexible stop 2-2 deforms elastically, allowing the cutter cylinder to be easily removed. After the cutter cylinder is installed, flip the pull ring 3-3 to one side of the cutter cylinder and fold it up. This will not affect the rotation of the cutter cylinder and the discharge of materials.

[0095] Furthermore, referring to Figure 17 As shown, a blind cap 3-7 for sealing the drive shaft hole 3-6 is also provided on the inner side of the tail of the blade body 3-1. The blind cap 3-7 can be made of metal material and is fixed together with the tail of the blade body 3-1, so that the opening of the drive shaft hole 3-6 facing the inside of the blade body is sealed. This can prevent food from directly contacting the transmission connector 4-3, achieve separation of power and food, ensure food safety and facilitate cleaning of the cutter.

[0096] [Example 3]

[0097] Based on Embodiment 1 or Embodiment 2 described above, this embodiment further provides a handheld electric roller vegetable cutter. (Refer to...) Figure 8 , Figures 14 to 22 As shown, the roller-type vegetable cutter of this embodiment uses an electric drive mechanism 4, which serves as a gripping handle, allowing for handheld operation and solving the problem of poor flexibility in existing fixed-use roller-type vegetable cutters. In use, one hand holds the drive mechanism 4, while the other hand feeds ingredients into the feeding cylinder 1-1 and presses them down with the pressure device 2. Activating the drive mechanism 4 rotates the blade cylinder, using the blades to chop the ingredients. The chopped ingredients enter the inner side of the blade cylinder and are discharged from the front outlet. By utilizing the compact electric drive mechanism as both a gripping handle and a power source, the relative position between the cutter's outlet and the container can be flexibly controlled, making it more flexible and convenient to use. Furthermore, it reduces intermediate loading steps, enabling "ready to use immediately after cutting."

[0098] Specifically, such as Figures 15 to 17 as well as Figures 20 to 22As shown, the aforementioned drive mechanism 4 includes a front housing 4-1, a rear housing 4-2, a transmission connector 4-3, a reducer 4-5, and a motor 4-6. The reducer 4-5 and the motor 4-6 are connected to form an integrated geared motor, which can be installed as a single component. The geared motor is fixedly connected to the rear housing 4-2 with screws, and the front housing 4-1 is fixedly connected to the geared motor with screws, achieving a secure connection between the three. The front housing 4-1 and the rear housing 4-2 are joined together along the axial direction of the geared motor to form a cavity for accommodating the geared motor, allowing the geared motor to be securely installed inside the front and rear housings. The output shaft of the geared motor is coaxially connected to the transmission connector 4-3 located outside the front housing 4-1, and the geared motor drives the transmission connector 4-3 to rotate, outputting speed and torque. Using the aforementioned drive mechanism 4, the structure is compact and small, providing comfortable and convenient handheld gripping operation. The installation structure is simple and easy to assemble. The small joint size after the front and rear housings are assembled facilitates sealing, provides good waterproof performance, and ensures a smooth gripping surface for comfortable and flexible use. In addition, to improve the waterproof performance of the handheld power handle, the joint between the front housing 4-1 and the rear housing 4-2 can be sealed with adhesive, which not only improves the overall waterproof performance of the handheld power handle, but also further enhances the connection strength between the front and rear housings.

[0099] To facilitate screw installation, the central axis of the screw is parallel or approximately parallel to the output shaft axis of the geared motor. In other words, the screw is installed along the axial direction of the drive mechanism 4. This installation method is simple and convenient, and the connection is secure and reliable. The connection between the front and rear housings and the geared motor can include two scenarios. One scenario involves a direct screw connection between the front housing 4-1, the geared motor, and the rear housing 4-2. Corresponding through holes can be provided on the front housing 4-1 and the geared motor. A long screw is then passed through these through holes and screwed onto the rear housing 4-2 to achieve a locking and securing effect. The other scenario involves a two-stage connection: first, the geared motor and the rear housing 4-2 are connected with screws, and then the front housing 4-1 and the geared motor are connected with screws. This embodiment preferably uses the latter method. (Refer to...) Figure 16 and Figure 21As shown, the rear housing 4-2 has a rear housing screw hole 4-2a, which can be integrally formed on the connecting post on the inner wall of the rear housing 4-2. The outer shell of the reducer 4-5 has a front housing screw hole 4-5a and a through hole 4-5b. The position of the through hole 4-5b is opposite to the position of the rear housing screw hole 4-2a. The geared motor is fixedly connected to the rear housing 4-2 by a first screw that passes through the through hole 4-5b and is screwed into the rear housing screw hole 4-2a. The front housing 4-1 has a front housing connecting hole 4-1a, which is opposite to the position of the front housing screw hole 4-5a. The front housing 4-1 is fixedly connected to the geared motor by a second screw that passes through the front housing connecting hole 4-1a and is screwed into the front housing screw hole 4-5a. The above installation logic is reasonable, the assembly accuracy is high, and the assembly is convenient and quick. It should be understood that there is more than one first screw and one second screw. The specific number can be determined according to the needs. For example, in this embodiment, two first screws are used to fix the geared motor to the rear housing 4-2, and four second screws are used to fix the front housing 4-1 to the geared motor.

[0100] To facilitate the assembly and disassembly of the cutting tube and the drive mechanism 4, a rotary locking structure is preferably used to connect them. This makes the connection and disassembly of the cutting tube and the drive mechanism 4 simple, convenient, quick, and the connection firm and stable. See details... Figure 14 and Figure 15 or Figure 19 and Figure 20 As shown, the front end face of the drive mechanism 4 is provided with a plug-in portion 4-1-1 and a rotating buckle 4-1-2. The plug-in portion 4-1-1 and the rotating buckle 4-1-2 can be formed on the front end face of the front housing 4-1. The tail end of the cutting tube is provided with a plug-in hole 1-4 and a rotating groove 1-5. The outer diameter of the plug-in portion 4-1-1 is adapted to the inner diameter of the plug-in hole 1-4, so that the plug-in portion 4-1-1 can be inserted into the plug-in hole 1-4 and rotate relative to the axial direction. The rotating buckle 4-1-2 is provided on the outside of the plug-in portion 4-1-1, and the rotating groove 1-5 is provided on the outside of the plug-in hole 1-4. The rotating buckle 4-1-2 can be inserted into and rotated into the rotating groove 1-5, realizing the connection between the cutting tube and the drive mechanism 4. The above-mentioned rotating buckle 4-1-2 and rotating groove 1-5 are provided in at least two in the circumferential direction to ensure the reliability of the connection between the two.

[0101] When operating by hand, one hand grips the drive mechanism 4 while the other hand feeds ingredients and operates the pressure plater 2. During this process, the hand gripping the drive mechanism 4 must bear the weight of the entire cutter and the downward pressure of the pressure plater 2, which can easily lead to strenuous operation. Figures 7 to 9As shown, for ease of operation, several raised ribs 1-1-1 are provided on the outer wall of the feeding cylinder 1-1. Under normal circumstances, 2 to 3 raised ribs 1-1-1 can be arranged at intervals along the height direction of the feeding cylinder 1-1. When operating the presser 2, one hand can hold the raised ribs 1-1-1 to press the presser 2, which can effectively share the weight and pressure borne by the other hand, further improving the ease and flexibility of hand operation of the roller-type vegetable cutter.

[0102] [Example 4]

[0103] Based on the above embodiment 3, the driving mechanism 4 can adopt various shapes that are convenient for hand operation, such as a straight handle or a triangular handle. (Refer to...) Figures 8 to 17 As shown, this embodiment is a triangular-handled handheld roller cutter. The drive mechanism 4 of this triangular-handled handheld roller cutter is triangular in shape and has a gripping part 4-2A. One end of the gripping part 4-2A is connected to the tail of the main body of the drive mechanism 4, and the other end of the gripping part 4-2A is connected to the front of the main body of the drive mechanism 4 through a vertical part, forming a roughly triangular structure, which is novel in design. The gripping part 4-2A is located on the upper part of the main body of the drive mechanism 4, which is convenient for gripping and operation, comfortable to grip, and highly practical. In addition, the rear side wall of the feeding cylinder 1-1 is in contact with the front side wall of the vertical part of the gripping part 4-2A. The upper part of the rear side wall of the feeding cylinder 1-1 has an upper slot 1-6, and the upper part of the front side wall of the vertical part has an upper buckle 4-2B that cooperates with the upper slot 1-6. The upper slot 1-6 has a side opening. When the cutting tube and the drive mechanism 4 are rotated and engaged, the upper buckle 4-2B and the upper slot 1-6 can rotate relative to each other around the aforementioned rotation axis to achieve a fastening connection, which further strengthens the connection strength, ensures the overall structural strength of the vegetable cutter, and makes it less likely for the feeding tube to shake during use.

[0104] Reference Figure 17 As shown, in this embodiment, the rear housing 4-2 is an integral structure, containing a battery 4-7 and a circuit board 4-8. The reducer 4-5 and motor 4-6 are located within the main body of the rear housing 4-2, while the battery 4-7 is located within the grip portion 4-2A. A button 4-4 is located at the front of the grip portion 4-2A. The button 4-4, motor 4-6, battery 4-7, and circuit board 4-8 are electrically connected to form a switch control circuit. The battery 4-7 provides power to the motor 4-6, and the button 4-4 controls the switching action of the motor 4-6. A charging port is also provided on the rear housing 4-2, and the circuit board 4-8 has a charging circuit for charging the battery 4-7. The wireless design provides greater flexibility and comfortable operation. This switch control circuit is a conventional circuit, and its specific circuit principle will not be elaborated here.

[0105] In addition, such as Figure 16As shown, the front housing 4-1 has a lower cover that matches the shape of the front part of the main body of the rear housing 4-2 and an upper cover that matches the shape of the front part of the vertical part. The lower cover and the upper cover are integral structures, and the upper cover is also reinforced by screws connecting it to the vertical part. A cover plate 4-1-3 is also provided on the front side wall of the front housing 4-1. This cover plate 4-1-3 can be made of stainless steel and is adhered to the front housing 4-1. It serves both a decorative purpose and also covers the screw holes on the front housing 4-1, preventing dirt and grime from accumulating in the screw holes and facilitating the cleaning of the drive mechanism 4.

[0106] [Example 5]

[0107] Reference Figures 18 to 22 As shown, this embodiment is a straight-handle handheld drum vegetable cutter, and the drive mechanism 4 of this straight-handle handheld drum vegetable cutter is straight-handle shaped. Specifically, the rear housing 4-2 has a straight cylindrical structure, and the straight cylindrical handheld power handle is more convenient to grip and operate flexibly. At the front end of the rear housing 4-2, there is an expanded diameter section 4-2-2 for accommodating the geared motor. The front expanded diameter section can accommodate a larger and more powerful geared motor, and helps to ensure the overall compactness of the handheld part. Due to the size limitations of the handheld power handle and the design requirements of the reduction ratio, the reducer 4-5 can adopt a multi-stage gear reduction mechanism or a planetary gear reduction mechanism, etc., to ensure the structural compactness of the reducer 4-5 and a larger reduction ratio. In this embodiment, the rear housing 4-2 also contains a battery 4-7 and a circuit board 4-8. The front of the rear housing 4-2 is provided with a button 4-4. The button 4-4, the motor 4-6, the battery 4-7 and the circuit board 4-8 are electrically connected to form a switch control circuit. Battery 4-7 provides power to motor 4-6, and button 4-4 controls the switching action of motor 4-6. Button 4-4 can be located on the expanded diameter section 4-2-2 at the front of the rear housing 4-2, which is more ergonomic and facilitates operation. A charging port is also provided on the rear housing 4-2, and the circuit board 4-8 has a charging circuit to charge battery 4-7. This switch control circuit is a conventional circuit, and its specific circuit principle will not be elaborated here. Additionally, a tail cover 4-2-1 is provided at the rear of the rear housing 4-2. This tail cover 4-2-1 can be fixed to the rear of the rear housing 4-2 using techniques such as snap-fit, adhesive, or heat fusion. This allows the main body of the rear housing 4-2 to be continuous from front to back, facilitating the overall molding of the rear housing and enabling mold core-pulling design. Furthermore, the tail cover 4-2-1 is simple and convenient to install, facilitating the installation of components such as hanging ropes.

[0108] This invention discloses a residue removal structure and a drum-type vegetable cutter, solving the problem of residue difficulty in removing from processing tools such as drum-type vegetable cutters that rely on pressure feeders. By providing a removal port on the outer shell that communicates with the gap at the bottom of the pressure feeder, the last remaining material can be easily discharged. The design is ingenious, the structure is compact, and it is flexible and convenient to use. By applying the above-mentioned residue removal structure to a drum-type vegetable cutter, after the pressure feeder is pressed to the bottom of the feeding cylinder, the remaining food in the gap is discharged from the removal port on the cutting cylinder as the blade cylinder rotates. This solves the problem of the last piece of food remaining in the cutting cylinder and being unable to be discharged in existing drum-type vegetable cutters, further improving the practicality and convenience of the drum-type vegetable cutter. Compared with existing drum-type vegetable cutters, the drum-type vegetable cutter of this invention also has the following advantages:

[0109] a. With a pull ring at the front of the blade barrel body, the blade barrel can be easily disassembled using the pull ring. The blade barrel disassembly operation is simple and convenient, and there is no need to directly contact the blade barrel, making the operation safer. In addition, the pull ring can be folded up and unfolded on the blade barrel, and the folding up does not affect the output of food.

[0110] b. The drive mechanism's transmission connector and the blade cylinder are connected by a spiral interlocking structure. The blade cylinder will not separate from the transmission connector during rotation, ensuring stable and reliable transmission, and the blade cylinder is easy to assemble and disassemble. At the same time, a flexible stop block is used to axially limit the blade cylinder, effectively preventing static slippage without affecting the installation and disassembly of the blade cylinder, thus ensuring the stability of the blade cylinder inside the cutting tube during operation. Furthermore, the end cap set on the inner side of the tail of the blade cylinder body can prevent food from directly contacting the transmission connector, achieving separation of power and food, ensuring food safety and facilitating the cleaning of the cutter.

[0111] c. It features an electric drive mechanism that can also be used as a gripping handle, enabling handheld operation of the drum-type vegetable cutter. This solves the problem of poor flexibility in the use of existing fixed-use drum-type vegetable cutters. Utilizing a compact electric drive mechanism as both a gripping handle and a power source, the relative position between the cutter's outlet and the container can be flexibly controlled during use, making it more flexible and convenient to use. It also reduces intermediate loading steps, achieving "cut and use immediately." Furthermore, the aforementioned electric drive mechanism is compact and comfortable to hold, with a simple installation structure that is easy to assemble. The cutting cylinder and the handheld power handle are connected by a rotating locking structure, making connection and disassembly simple, quick, and the connection secure and stable.

[0112] d. Several ribs are provided on the outer wall of the feeding cylinder. The ribs on the feeding cylinder make it easy to hold and press the feeder with one hand, which can effectively share the weight and pressure borne by the other hand, further improving the ease and flexibility of hand operation of the roller-type vegetable cutter.

[0113] e. The drive mechanism is shaped like a straight handle or a triangular handle. When the drive mechanism is triangular, it has a gripping part. The triangular handle design is novel, and the gripping part is comfortable to hold and operate, making it highly practical. Furthermore, when the drive mechanism is triangular, a snap-fit ​​structure can be used between the feeding cylinder and the drive mechanism to further strengthen the connection and ensure the overall structural strength. The feeding cylinder is not easy to shake during use.

[0114] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
