Description

Technical Field

[0001] The present disclosure relates to the technical field of household juicers, and in particular to a core removal mechanism, a core remover, and a fruit juice making system. Background Art

[0002] Known orange juicers require the juice to be processed to the desired state before juicing. This involves at least slicing the orange in half or cutting it into small pieces. This cutting process causes the juice to leak, resulting in waste and pollution. Furthermore, juicers are bulky and difficult to carry. After processing the fruit, a lot of residue remains inside the juicer that needs to be cleaned.

[0003] If you're juicing an orange from the inside, you can make a blind hole or a through hole in the orange beforehand to allow access for a knife. Generally, you'll want to remove the core between the stem and the navel. However, if a blind hole is necessary, a simple knife can only sever the connection between the core's circumference and the main body of the fruit, making it difficult to cut between the base of the core and the main body of the fruit. This makes it difficult to remove the core from the fruit. Summary of the Invention

[0092] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0093] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0094] The core removal mechanism disclosed herein comprises a core cutter, a rotating drive, a cutting blade, and a cutting blade drive unit. The core cutter has a first end and a second end, the second end being provided with a blade. The rotating drive unit is disposed at the first end of the core cutter. The cutting blade has a first end and a second end, the first end of the cutting blade being hingedly connected to the first end of the core cutter or the rotating drive unit and abutting against the core cutter along its length. The cutting blade drive unit is connected to the first end of the cutting blade and protrudes radially outward from the core cutter. As the core cutter rotates with the rotating drive unit, the blade can cut a circular slit in the fruit. During rotation, the core cutter penetrates the fruit, and the circular slit expands into a cylindrical surface. The tissue within the cylindrical surface constitutes the core, which is separated from the main body of the fruit. When the core cutter is inserted to a certain depth, the cutting blade drive unit contacts the surface of the fruit. Under the axial force exerted by the fruit surface, the cutting blade drive unit drives the cutting blade to rotate, and the cutting blade begins to cut the core of the fruit until the core is severed. The cut core is completely separated from the fruit body, making it easy to remove. The rotating drive member can be connected to a handle or constructed with a handle portion, and the insertion and rotation operations are performed manually. It can also be connected to an electric tool, driven by the electric tool to rotate, and the insertion operation is performed manually.

[0095] refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of a core removal mechanism in one embodiment of the present disclosure. Figure 2 for Figure 1 Schematic diagram of the cutting knife 230 of the core removal mechanism when it is transferred into the core cutting knife 220. Figure 3 for Figure 1 Schematic diagram of the use status of the core removal mechanism. Figure 4 for Figure 1 The structural diagram of the middle cutting knife 230, Figure 5 for Figure 2 Schematic diagram of the core removal mechanism when viewed from above.

[0096] The core removal mechanism 200 includes a rotating drive member 210, a core cutter 220, a cutting knife 230, a cutting knife drive unit 240, and a connecting member 250. In this embodiment, the rotating drive member 210 is used to connect to a power device that can output rotational motion to drive the core cutter 220 connected thereto to rotate. The core cutter 220 is a thin-walled cylindrical structure. The cutting knife 230 and the cutting knife drive unit 240 are connected and fixed by the connecting member 250. When the cutting knife drive unit 240 is pushed and pulled along the axial direction of the core cutter 220, the cutting knife 230 can be driven to swing inside the core cutter 220. When the core removal mechanism 200 rotates and is inserted into the fruit, the cutting knife 230 adheres to the cylinder wall of the core cutter 220. When it is inserted into the surface of the fruit and pushes the cutting knife drive unit 240, the core cutter 220 begins to move away from the cylinder wall toward the center, thereby cutting the core inside the cylinder and severing it.

[0097] The rotary drive member 210 primarily comprises a power connection end 211 and a core cutter connection end 212. The power connection end 211 is used to connect to a power device, while the core cutter connection end 212 is used to connect to a core cutter 220. The power connection end 211 comprises a rod 213 and a first protrusion 214 provided on the rod 213. The rod 213 is a cylindrical rod, and the first protrusions 214 protrude from the circumference of the cylindrical rod. Specifically, the first protrusions 214 are shaped like a 120-degree obtuse angle, and there are six of them. The six first protrusions 214 surround the rod 213 to form a regular hexagon, with the center of the regular hexagon concentric with the rod 213. The core cutter connection end 212 is roughly cylindrical, with a diameter matching that of the core cutter 220, and the two are coaxially connected. The end surface of the core cutter connection end 212 is also provided with a groove and a radial hole. The radial hole is used to mount the hinge shaft 260, while the groove is used to accommodate the connector 250. The hinge shaft 260 forms a hinged relationship between the connecting member 250 and the rotating driving member 210. The rotating driving member 210 is fixedly connected to the core cutter 220, so the connecting member 250 can also be regarded as being hinged to the core cutter 220.

[0098] The core cutter 220 is a thin-walled cylindrical structure with a first end 221 and a second end 222. The first end 221 is sleeved onto the core cutter connection end 212 of the rotating drive member 210. The second end 222 has a blade 223. The core cutter 220 has two openings: a receiving groove 224 for accommodating the cutting blade 230, and an opening 225 for ejecting the fruit core. The receiving groove 224 and the opening 225 are arranged face-to-face. The second end 222 is a complete ring for cutting a circular hole in the fruit. Since the core cutter 220 cuts the fruit during rotation, the second end 222 can also be configured as an incomplete ring, such as a half ring or multiple concentric, equal-diameter ring segments, to create a circular hole in the fruit. In some alternative embodiments, the opening 225 may be omitted, and the cut core can be discharged from the outlet at the second end 222 of the core cutter 220.

[0099] The cutting blade 230 is a long, curved blade having a first end 231 and a second end 232. The cross-section of the cutting blade 230 is an arc, the diameter of which is equal to that of the core cutter 220. The width of the cutting blade 230 matches the width of the receiving slot 224. The first end 231 is hingedly connected to the core cutter connection end 212 of the rotating drive member 210, so that when the cutting blade 230 rotates relative to the core cutter connection end 212, the first end 231 can move into the core cutter 220. As the core cutter 220 rotates, the first end 231 can cut around the core portion to sever the core. Specifically, the cutting blade 230 is hingedly connected to the rotating drive member 210 via a connecting member 250. The cutting blade drive unit 240, connected to the connecting member 250, can receive external force to drive the connecting member 250 and the cutting blade 230 to move. More specifically, the first end 231 of the cutting blade 230 is provided with two fins, which are plugged into the connecting member 250. The connecting member 250 is hingedly connected to the core cutter connecting end 212 via a hinge 260, which is perpendicular to the centerline of the core cutter 220. One end of the cutting blade drive unit 240 is connected to the connecting member 250, while the other end protrudes radially from the core cutter 220. In this embodiment, it protrudes from the opening 225 of the core cutter 220.

[0100] When the cutting blade drive unit 240 is not under force, the cutting blade 230 can be embedded in the receiving groove 224 of the core cutter 220 without protruding from the surface of the core cutter 220. This can reduce interference between the cutting blade 230 and the surrounding flesh tissue during the rotation of the core cutter 220, preventing the flesh from entering between the cutting blade 230 and the core cutter 220 and pushing the cutting blade 230 to rotate radially, thereby prematurely cutting the core. In addition, when the cutting blade drive unit 240 is not under force, if the cutting blade 230 tends to enter the core cutter 220 during the rotation of the core cutter 220, the blade body located behind the first side 233 will encounter resistance from the core tissue, preventing the cutting blade 230 from unintentionally entering the interior of the core cutter 220 and cutting the core.

[0101] like Figure 3 and Figure 5 As shown, when the cutting blade 230 is inserted to a sufficient depth, the cutting blade driving unit 240 contacts the peel of fruit a and is subjected to a force along the axial direction of the core cutter 220, thereby driving the connecting member 250 and the cutting blade 230 to rotate about the hinge shaft 260, and the second end 232 of the cutting blade 230 gradually moves toward the centerline C of the core cutter 220. Since the core cutter 220 rotates as it enters the interior of the fruit a, the cutting blade 230 also rotates about the centerline C of the core cutter 220, allowing its first end 231 to cut and cut the core.

[0102] The intersection of the first side 233 and the terminal edge 236 of the cutting blade 230 (a corner of the second end 232) is where the interference with the fruit's core is greatest, providing the greatest cutting effect on the core. The closer the cutting blade 230 is to the first end 231, the less interference there is with the core. Since the core of an orange is soft and easily deformed, the portion farther from the second end 232 will have little significant cutting effect on the core. In this embodiment, a recessed portion 234 is provided at the intersection of the first side 233 and the terminal edge 236 of the cutting blade 230, thereby forming a sharp corner 235 at the second end 232. This sharp corner 235 provides a greater cutting effect on the fruit flesh. The recessed portion 234 itself also gathers some of the core tissue, preventing it from easily sliding toward the first end 231 and making it difficult to cut the core. In this embodiment, the recessed portion 234 is provided on the first side 233; in some alternative embodiments, it can also be provided on the terminal edge 236.

[0103] refer to Figure 5 In this embodiment, the first side 233 of the cutting blade 230 is coplanar with a plane P perpendicular to the hinge shaft 260 and passing through the center line C of the core cutter 220. That is, when the cutting blade 230 rotates around the hinge shaft 260, the sweep plane of the first side 233 passes through the center line C of the core cutter 220. Figure 5 When viewed from the center, as the core cutter 220 rotates counterclockwise, the first side 233 rotates about the centerline C. The portion of the first side 233 located at the second end 232 can cut the core. In this embodiment, the cutting blade 230 is generally rectangular, with the first side 233 being a straight edge. The entire first side 233 lies in the aforementioned plane P.

[0104] The configuration of the cutting blade 230 is not limited to that described in the aforementioned embodiment. For example, in some optional embodiments, part of the side of the first side 233 (such as the side near the second end 232) coincides with the aforementioned plane (the plane perpendicular to the hinge shaft 260 and passing through the center line C of the core cutter 220), and other parts are not limited. In other optional embodiments, the cutting blade 230 can also be configured so that its side for cutting does not coincide with the plane P perpendicular to the hinge shaft 260 and passing through the center line C of the core cutter 220, for example, it is located on one side of the plane (i.e. Figure 5 The first side edge 233 of the core cutter 220 may be offset to the left or right, or may intersect the plane. In some optional embodiments, the cutting blade 230 may be located outside the core cutter 220. When the cutting blade driving unit 240 is subjected to force, the cutting blade 230 may pass through the receiving groove 224 and enter the interior of the core cutter 220. In other optional embodiments, the receiving groove 224 may not be provided, and the cutting blade 230 may be located inside the core cutter 220 and be in contact with the inner wall of the core cutter 220.

[0105] The connection method of the cutting blade 230 is not limited to the method described in the above embodiment. For example, in some optional embodiments, the cutting blade driving part 240 and the connecting member 250 are an integrated structure; in other optional embodiments (such as Figure 11 The cutter blade is L-shaped and includes a horizontal portion 240a and a vertical portion 230a. The vertical portion 230a is used for cutting, while the horizontal portion 240a serves as a cutter blade drive. A sleeve 250a is provided near the corner as a connector, forming a hinged connection with the core cutter 220 or the core cutter connection end 212. In other optional embodiments, the cutter blade can also be hinged to the core cutter 220.

[0106] The shape of the cutting knife 230 is not limited to the structure described in the aforementioned embodiment. It can also be a flat strip structure with a very small width. Although the cutting knife with an arc-shaped cross-section has greater resistance when rotating with the core cutting knife 220, it can also basically achieve the cutting function.

[0107] In the aforementioned embodiment, the power connection end 211 of the core removal mechanism 200 and the rotary drive member 210 is configured for connection to a specific power device. In some embodiments, the power connection end 211 may also have other structures, such as threads, a D-shaped cross-section shaft, or other known structures capable of transmitting torque and rotational motion.

[0108] The core removal mechanism in the aforementioned embodiment can be used in conjunction with a power tool capable of providing rotational motion. The power tool is connected to the power connection end 211 of the rotary drive member 210 to drive the core cutter 220 to rotate. In some embodiments, the core removal mechanism can also be configured for manual use. For example, the power connection end 211 of the core removal mechanism 200 in the aforementioned embodiment can be replaced with a handle, such as a T-shaped handle with a horizontal bar for easy gripping and a vertical bar connected to the core cutter connection end 212 to drive the core cutter 220. Alternatively, a handle of any other shape can be used to facilitate gripping and applying the rotational driving force.

[0109] refer to Figure 6 , Figure 6 FIG2 is a schematic structural diagram of the second end 232a of the cutting blade in another embodiment. In this embodiment, a protruding sharp corner 235a is provided on the side of the cutting blade, and one side of the sharp corner 235a is coplanar with the end side 236a of the second end 232a.

[0110] refer to Figures 7 to 15 . Figure 7 This is a schematic structural diagram of a core remover in one embodiment of the present disclosure; Figure 8 for Figure 7 AA cross-sectional view; Figure 9 Schematic diagram of the relationship between the rotating output shaft 120 and the rotating driving member 210; Figure 10Schematic diagram of the relationship between the rotating output shaft 120a and the rotating driving member 210a in another embodiment; Figure 11 A schematic structural diagram of a cutting knife in another embodiment; Figure 12 for Figure 9 An exploded schematic diagram of the rotating output shaft 120; Figure 13 for Figure 12 A schematic structural diagram of the inner shaft 12b; Figure 14 for Figure 12 A schematic structural diagram of the middle and outer shafts 12a; Figure 15 for Figure 14 A schematic structural diagram of the inner and outer shafts 12a from another viewing direction.

[0111] The core remover includes a power device 100 and a core removing mechanism 200 . The core removing mechanism 200 is detachably mounted on the power device 100 , and the power device 100 can drive the core removing mechanism 200 to rotate.

[0112] The power unit 100 has a rotating output shaft 120, and the core removal mechanism 200 is detachably connected to the rotating output shaft 120. The rotating output shaft 120 is driven by a motor and a reducer. The rotating output shaft 120 is arranged in a hole of the power unit 100 to form a rotating connection. Compared with a cantilever output shaft, the rotating output shaft 120 installed in this shaft-hole matching form has a longer shaft section supported, and therefore has a greater bending resistance. In addition, the hole of the power unit 100 bears the bending moment of the rotating output shaft 120, and the output shaft 800 of the motor or the reducer is not affected by the bending moment of the rotating output shaft 120. A needle bearing 900 can be arranged between the rotating output shaft 120 and the hole of the power unit 100 to reduce frictional resistance. One end of the rotating output shaft 120 is exposed, and the end face is provided with a mounting hole 128, and the mounting hole 128 is used to connect the core removal mechanism 200. During use, the portion of the coring mechanism 200 that is detachably connected to the mounting hole 128 is inserted into the mounting hole, allowing the coring mechanism 200 to rotate along with the rotating output shaft 120. Furthermore, the portion of the coring mechanism 200 that is detachably connected to the mounting hole is located within the mounting hole, and an axial stop structure is provided between the portion and the mounting hole to prevent undesirable axial disengagement.

[0113] Specifically, the power device 100 includes a body 110 and a rotating output shaft 120. The body 110 accommodates a battery, a motor, and the rotating output shaft 120. The rotating output shaft 120 is rotatably connected to the body 110 via a shaft hole. The body 110 can be held.

[0114] The rotating output shaft 120 includes an outer shaft 12a and an inner shaft 12b. The outer shaft 12a is provided with a central through hole. The inner shaft 12b is provided with a blind hole. The inner shaft 12b is sleeved within the central through hole of the outer shaft 12a to form the rotating output shaft 120. A fitting hole 14b is provided at one end of the inner shaft 12b. The fitting hole 14b has a rounded rectangular shape. An adapter 700 is embedded in the fitting hole 14b. The inner hole of the adapter 700 is a D-shaped hole. The blind hole of the inner shaft 12b is a circular hole. The central through hole of the outer shaft 12a and the blind hole of the inner shaft 12b together form the mounting hole 128 of the rotating output shaft 120. The mounting hole 128 includes a hexagonal hole section 121 and a circular hole section 122. The hexagonal hole section 121 is located at the hole mouth, and the circular hole section 122 is located inside. The hexagonal hole section 121 is provided with a first groove and a second groove 125. The hole wall of the hexagonal hole segment 121 is composed of six planes with an angle of 120 degrees. The junction of two adjacent hole walls can be regarded as a V-shaped groove, such as the V-shaped groove 129 formed by the first hole wall 123 and the second hole wall 124. There are six V-shaped grooves, all of which extend along the axial direction of the mounting hole. The V-shaped groove 129 is the first groove. A second groove 125 is also provided on each hole wall. The second groove 125 starts from the boundary of the second hole wall 124 (the boundary line between the second hole wall 124 and the first hole wall 123) and extends circumferentially. One end of the V-shaped groove 129 starts from the end face of the rotating output shaft 120, and the other end is connected to the second groove 125. The end wall 126 of the second groove 125 is used to contact the first protrusion 214 of the rotating connector 210 to transmit torque.

[0115] The core removal mechanism 200 may be the structure of the aforementioned embodiment, such as Figure 3 For details of the structure shown, please refer to the above description. The power connection end 211 of the rotating connector 210 is used to form a removable connection with the mounting hole 128 of the rotating output shaft 120, which can transmit torque. Specifically, it includes a rod portion 213 and a hexagonal prism segment. The hexagonal prism segment is relatively short and therefore relatively flat, i.e., a hexagonal sheet. The six sharp corners of the hexagonal prism segment form radial protrusions (first protrusions 214) along the rod portion 213. The rod portion 213 is configured to be inserted into the mounting hole 128 and form an axial hole with the circular hole segment 122. The six sharp corners of the hexagonal prism segment are adapted to the hexagonal hole segment 121 of the rotating output shaft 120. The six sharp corners can slide along the V-shaped groove and reach the first end (entrance) of the second groove 125. Then, they can rotate to enter the interior of the second groove 125. The two side walls of the second groove 125 provide axial restraints for the six corners. The end wall 126 at the second end of the second groove 125 and the first protrusion 214 form a torque transmission structure. The two side walls of the second groove 125 refer to wall surfaces normal to the axial direction (the end surface 13 b and the surface facing it).

[0116] During installation, after aligning the first protrusion 214 with the V-shaped groove 129, the rotating connector 210 is inserted into the mounting hole 128 of the rotating output shaft 120 and then rotated a predetermined angle. The rotating output shaft 120 then axially limits the rotating connector 210 and forms a torque-transmitting connection, simplifying installation. During removal, the first protrusion 214 of the rotating connector 210 needs to be aligned with the V-shaped groove 129 before being moved axially (in the direction of the V-shaped groove 129). To facilitate alignment of the first protrusion 214 with the V-shaped groove 129, the connection between the V-shaped groove 129 and the second groove 125 of the rotating output shaft 120 is L-shaped in the present disclosure. That is, the starting end of the second groove 125 is flush with the sidewall of the V-shaped groove 129. This allows the rotating connector 210 to be removed by rotating it to its limit position (the sidewall of the V-shaped groove 129) and then pulling it outward, without the need to deliberately align the first protrusion 214 with the V-shaped groove 129. This can increase the convenience of operation.

[0117] In the rotating connector 210, the hexagonal prism-shaped sharp corners of the first protrusion 214 are a relatively special radial protrusion. The first protrusion can also be in other forms, such as a quadrangular prism-shaped protrusion, or the end of a radial pin protruding from the rod 213, or a structure protruding from the rod 213 formed by other processes. Of course, the cross-sectional shapes of the V-shaped groove 129 and the second groove 125 of the mounting hole should also be compatible with the first protrusion. Figure 10 As shown, a schematic diagram of the relationship between the rotating output shaft 120a and the rotating connecting member 210a in another embodiment is shown. The first protrusion 214a is a 90-degree sharp angle, the mounting hole is a round hole, and the first groove is a V-shaped groove 129a adapted to the sharp angle. The function of the V-shaped groove 129a is to guide the radial protrusion of the rotating connecting member 210a to the second groove 125a. The second groove 125a is used to generate axial limitation for the first radial protrusion and generate torque on the first protrusion 214a through the end wall 126a. During implementation, the number and specific shape of the three can be determined according to actual needs or production and processing conditions, and are not limited to the structure described in the embodiment of the present disclosure.

[0118] In some optional embodiments, the detachable connection between the core removal mechanism 200 and the power device 100 may be other structures. For example, an external thread may be provided on the power connection end 211 of the rotary drive member 210, and an internal thread may be provided in the mounting hole of the rotary output shaft 120, so as to achieve detachable connection and torque transmission through the threaded connection.

[0119] In some optional embodiments, the core removal mechanism 200 and the power device 100 may also be fixedly connected.

[0120] refer to Figure 16 、 Figure 17 and Figure 7 . Figure 16This is a schematic structural diagram of a fruit juice making system according to an embodiment of the present disclosure; Figure 17 for Figure 16 Schematic diagram of the use of the middle pulp scraper 300 when connected to the power device.

[0121] The fruit juice making system includes a power device 100, a core removal mechanism 200 and a pulp scraper 300. The core removal mechanism 200 and the pulp scraper 300 are configured to interchangeably form a detachable connection with the power device 100 that can transmit torque. The structure of the core removal mechanism 200 can refer to the description in the aforementioned embodiment and will not be repeated here. When the core removal mechanism 200 is connected to the power device 100, the power device 100 is held so that it drives the core removal mechanism 200 to be rotationally inserted into the fruit a, cutting a cylindrical incision in the fruit a, separating the core (pulp / core) in the incision from the main body of the fruit, making it easier to remove the core and thus forming a blind hole in the fruit a. Fruit a is an orange. Afterwards, the core removal mechanism 200 is removed from the power unit 100, and the pulp scraper 300 is connected to the power unit 100. One end of the pulp scraper 300's blade is inserted into the blind hole of fruit a. The power unit 100 is activated to rotate the pulp scraper 300, and the power unit 100 is swung within the space so that the pulp scraper 300's blade end scrapes the pulp as far as possible within fruit a until it contacts the orange peel. As the pulp scraper 300 rotates, it experiences a resistance torque from the pulp, and the power unit 100 provides the corresponding torque to drive the pulp scraper 300's rotation. The pulp and juice scraped by the pulp scraper 300 can be temporarily stored within fruit a. After scraping, the juice can be directly sucked from the fruit using a straw.

[0122] The fruit scraper 300 includes a rod 310, a scraper 320, and a connecting portion 330. The scraper 320 is located at the second end 312 of the rod 310, and the connecting portion 330 is located at the first end 311. The first end 311 is a short section of the rod at the end. The connecting portion 330 is 10 to 20 mm away from the end surface of the rod 310. The length of the rod 310 is approximately 120 mm, which is consistent with the diameter of the fruit to be processed. The scraper 320 includes four curved blades that protrude from the surface of the rod 310. The scraper 320 is made by removing material from a hollow sphere. A through hole is cut into the hollow sphere to form a hole for connection to the rod 310. Four windows are then cut around the through hole. A portion of the sphere remains between the windows and between the windows. The spheres between the windows form the curved blades. The spheres can be formed by joining two hemispheres. The hemispheres can be stamped from metal sheets. The scraper 320 is a unitary body comprising multiple curved blades, which are conveniently connected to the rod 310. Of course, the scraper can also be formed by separate curved blades, each directly connected to the rod 310. The number of curved blades can also be greater or lesser, such as three, two, or five. The scraper can also be a spherical structure with ridges or protrusions on its surface, which can squeeze and scrape the fruit pulp during rotation. The scraper can also be a sphere with multiple recessed portions on its surface, where the intersection of the recessed portions and the spherical surface can form an angled surface for scraping.

[0123] The connecting portion 330 is used to form a detachable connection with the rotating output shaft 120 that can transmit torque, and the connecting portion 330 is provided with a second radial protrusion. In this embodiment, the connecting portion 330 has a substantially identical structure to the first protrusion 214 and the rod portion 212 of the rotating connector 210. The connecting portion 330 includes a cylindrical section 332 and a hexagonal prism section and is provided with a center hole. The connecting portion 330 is sleeved on the rod 310 through the center hole. The sharp corner 331 of the hexagonal prism section is a second radial protrusion, and the sharp corner 331 is used to cooperate with the hexagonal hole section 121 of the rotating output shaft 120, that is, with the V-shaped groove 129 and the second groove 125; the cylindrical section 332 is used to cooperate with the circular hole section 122 of the rotating output shaft 120. The rod 310 is a hollow tube and can be used as a straw. Because the pulp scraper 300 is connected to the rotary output shaft 120 via the connection portion 330, the first end 311 of the rod 310 does not contact the power device 100, keeping the first end 311 clean and making it more hygienic to suck on this area with the lips. In some alternative embodiments, the connection portion 330 may not include the cylindrical section 332. The sharp corner 331 is used to transmit torque, and the first end 311 forms a shaft hole with the mounting hole 128 of the rotary output shaft 120 to withstand bending moments.

[0124] In this embodiment, the connecting portion 330 and the rod 310 are separate components that are connected to form a single piece through assembly. In some alternative embodiments, the two may be integrally formed, such as by machining or other molding processes. In some alternative embodiments, the rod 310 may be solid; in other alternative embodiments, the connecting portion 330 may be disposed at the distal end of the first end 311. In some alternative embodiments, the second radial protrusion may be disposed directly on the surface of the rod 310, used to transmit torque, and the first end 311 may form a shaft hole with the mounting hole of the rotating output shaft 120 to withstand bending moments. In other alternative embodiments, the connecting portion 330 may be a portion of the rod 310, such as an externally threaded section disposed on the surface of the first end 311, which may also be a connecting portion, and the corresponding rotating output shaft 120 may also be threaded to form a removable connection with the first end 311. Of course, corresponding threads should also be disposed on the rotating connector 210 of the core removal mechanism 200. In other optional embodiments, the cylindrical surface of the connecting portion 330 may not be provided with the second radial protrusion, but may be provided with an external thread; correspondingly, an internal thread should also be provided in the mounting hole of the rotating output shaft 120.

[0125] The larger the diameter of the scraper 320 of the pulp scraper 300, the more efficient the pulp scraping. Generally, the diameter of the core cutter 220 of the fruit opener 200 is greater than or equal to the diameter of the scraper 320 to facilitate the scraper 320's entry and exit of the fruit. However, the larger the hole opened by the fruit opener 200, the more pulp is removed and wasted. The present disclosure sets the diameter of the scraper 320 to be larger than the diameter of the core cutter 220. At the same time, the second radial protrusion in the pulp scraper 300 forms an axial limit with the second groove 125 of the rotating output shaft 120, allowing the pulp scraper 300 to resist axial pulling forces and not escape from the rotating output shaft 120. In this way, even if the diameter of the hole in the fruit is smaller than the diameter of the scraper 320, the scraper 320 can squeeze and deform the hole, allowing it to enter or escape from the hole. If the system with the above functions needs to process two fruits continuously, the opener 200 can be used to make holes in the two fruits, and then the pulp scraper 300 can be used to process the pulp inside the fruits one by one. When the pulp scraper 300 is pulled out from the first fruit, the pulp scraper 300 is not easy to fall off, which can ensure continuity and reduce the possibility of interruption.

[0126] In some optional embodiments, a rubber pad serving as a seal is provided at the bottom of the blind hole 128 of the rotating output shaft 120. The rod 310 of the pulp scraper 300 is a hollow tube. When the rod 310 is attached to the rotating output shaft 120, the first end 311 of the rod 310 presses against the rubber pad, forming a sealed contact between the two. When scraping the pulp, the pulp scraper 300 may move up and down repeatedly within the tube a. When pressed downward, pulp or juice may enter the tube due to external forces. However, when one end is sealed, air pressure can be used to prevent pulp or juice from entering the hollow tube, preventing the juice from entering the blind hole 128.

[0127] The present disclosure also provides a pulp scraping device comprising the power unit coring mechanism 200 and a pulp scraper 300 described in the aforementioned embodiment. The pulp scraper 300 has a hollow tube-shaped rod 310. A seal is provided at the portion of the coring mechanism 200 that connects to the pulp scraper 300. When the pulp scraper 300 is connected to the coring mechanism 200, the seal contacts the end surface of the rod 310, forming a sealed connection. This pulp scraping device is equivalent to the sealed in-fruit juice extraction system described in the aforementioned embodiment, minus the coring mechanism 200.

[0128] The foregoing description is intended only to provide specific embodiments of the present disclosure, intended to enable those skilled in the art to understand and implement the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is not intended to be limited to the embodiments described herein, but rather to be construed in the broadest manner consistent with the principles and novel features disclosed herein.
