Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and more particularly to a shredder. Background Technology

[0002] In related technologies, the chopper in a handheld blender is commonly used to chop ingredients such as pork or beef. A traditional chopper consists of a main unit, a cup, a lid, and blades. The main unit is controlled by a momentary switch; to remove ingredients from the cup, the momentary switch must be released and the lid removed. Traditional choppers allow the main unit and lid to be lifted together without releasing the momentary switch, separating the lid from the cup. However, the chopper blades remain rotating due to inertia. Even after the lid and cup are separated, the still-rotating blades can directly contact the operator, potentially causing injury. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a shredder that can reduce the probability of accidental injury to the operator.

[0004] Embodiments of this application provide a shredder, comprising:

[0005] A chopping cup having a receiving cavity with an opening at the upper end;

[0006] The tool holder assembly is rotatably mounted within the receiving cavity;

[0007] A housing assembly, including a first housing that covers the opening;

[0008] The inner cover is detachably disposed in the receiving cavity. The inner cover is located between the first housing and the tool holder assembly. The inner cover is provided with a clearance channel at the rotation axis of the tool holder assembly.

[0009] The driving device includes a transmission assembly and a driving mechanism. The transmission assembly is mounted on the first housing and is connected to the rotating shaft. The driving mechanism drives the tool holder assembly to rotate through the transmission assembly.

[0010] Furthermore, the chopping cup is provided with a support portion corresponding to the position of the inner lid, and the support portion abuts against the bottom of the inner lid.

[0011] Furthermore, it also includes an interlocking assembly, which includes a first interlocking structure and a second interlocking structure. The first interlocking structure is disposed on the cavity wall of the receiving cavity, and the second interlocking structure is disposed on the first housing. Rotating the first housing enables the second interlocking structure and the first interlocking structure to switch between an engaged state and a disengaged state.

[0012] Furthermore, the first interlocking structure includes a circumferentially extending engagement groove, and the second interlocking structure includes a protrusion that engages with the engagement groove.

[0013] Furthermore, the first housing includes an abutment portion and a mating portion, the mating portion being disposed below the abutment portion, and a gap being present between the mating portion and the edge of the abutment portion, wherein the bottom of the abutment portion abuts against the top of the chopping cup, and the mating portion mates with the inner wall of the receiving cavity.

[0014] Furthermore, the inner cover is provided with a raised baffle, which is arranged in a ring, and the clearance channel is located within the enclosure of the raised baffle.

[0015] Furthermore, the drive mechanism is detachably connected to the transmission assembly.

[0016] Furthermore, the driving device includes a jog switch, which is electrically connected to the driving mechanism and is used to control the driving mechanism.

[0017] Furthermore, the transmission assembly includes a first transmission member, the tool holder assembly includes a tool holder, the tool holder has the rotating shaft, one end of the rotating shaft is rotatably connected to the receiving cavity, and the other end of the rotating shaft is connected to the first transmission member.

[0018] Furthermore, the transmission assembly includes a coupling joint, which is detachably connected to the first transmission component and the rotating shaft. The coupling joint has an axial portion and a first limiting portion and a second limiting portion spaced apart from the axial portion. The axial portion cooperates with the clearance channel, and the inner cover is located between the first limiting portion and the second limiting portion.

[0019] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects:

[0020] In the shredder provided in this application, an inner cover is provided between the first housing and the blade holder assembly. After use, the drive mechanism and the first housing need to be removed first. At this time, the first housing drives the transmission assembly to separate from the rotating shaft of the blade holder assembly, so that the drive mechanism can no longer drive the blade holder assembly to rotate. After the first housing is removed, an inner cover is also provided on the top of the blade holder assembly. Even if the blade holder assembly continues to rotate due to inertia, the presence of the inner cover can separate the operator from the blade holder assembly. The user's hand cannot be directly inserted into the receiving cavity of the shredding cup. Thus, it can prevent the still rotating blade holder assembly from accidentally injuring the operator, which helps to improve the safety of using the shredder. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] See Figure 1 and Figure 2 As shown, a traditional chopper includes a main unit 4, a cup body 1, a lid 2, a blade holder 3, and blades 5. The main unit 4 is controlled by a momentary switch; to remove food from the cup body 1, the momentary switch must be released and the lid 2 removed. However, with a traditional chopper, the main unit 4 and lid 2 can be lifted together without releasing the momentary switch, separating the lid 2 from the cup body 1. At this point, the chopper blades 5 are still rotating due to inertia. After the lid 2 separates from the cup 1, the still-rotating blades 5 can directly contact the operator, potentially causing accidental injury.

[0038] In view of this, this application proposes a shredder to effectively solve the aforementioned problems.

[0039] See Figures 3 to 6 As shown, an embodiment of this application discloses a shredder, including a shredding cup 100, a blade holder assembly, a housing assembly, an inner cover 400, and a drive device.

[0040] Specifically, the chopping cup 100 has a receiving cavity 110 with an opening at its upper end; the blade holder assembly is rotatably mounted inside the receiving cavity 110; the housing assembly includes a first housing 310, which covers the opening; an inner cover 400 is detachably disposed inside the receiving cavity 110, located between the first housing 310 and the blade holder assembly, and the inner cover 400 has a clearance channel 410 corresponding to the rotation shaft 211 of the blade holder assembly; the driving device includes a transmission assembly and a driving mechanism 520, the transmission assembly is mounted on the first housing 310 and connected to the rotation shaft 211, and the driving mechanism 520 drives the blade holder assembly to rotate through the transmission assembly.

[0041] In the shredder provided in this embodiment, an inner cover 400 is provided between the first housing 310 and the blade assembly. After use, the drive mechanism 520 and the first housing 310 need to be removed first. At this time, the first housing 310 drives the transmission assembly to separate from the rotating shaft 211 of the blade assembly, so that the drive mechanism 520 can no longer drive the rotating shaft 211 of the blade assembly to rotate. After the first housing 310 is separated from the shredding cup 100, the inner cover 400 is still provided above the blade assembly. Even if the rotating shaft 211 of the blade assembly is still rotating due to inertia, the inner cover 400 can separate the operator from the blade assembly, and the operator's hand cannot be directly inserted into the receiving cavity 110 of the shredding cup 100. Thus, the rotating blade assembly can prevent the operator from being accidentally injured by the blade assembly. After the blade assembly stops rotating, the inner cover 400 is removed from the shredding cup 100. In this way, the operator can be effectively prevented from being accidentally injured by the blade assembly, which helps to improve the safety of using the shredder.

[0042] In one embodiment, the inner cover 400 matches the opening of the receiving cavity 110, thereby reducing the likelihood of food flying out of the blade assembly or the receiving cavity 110 and improving the safety performance of the chopper.

[0043] It is understandable that the inner cover 400 can be set as a disc-shaped structure or a disc-shaped structure with a hollow area; no limitation is made here.

[0044] In one embodiment, see Figure 4 and Figure 5 The chopping cup 100 has a support part 120 at the position corresponding to the inner lid 400, and the support part 120 abuts against the bottom of the inner lid 400. By abutting against the bottom of the inner lid 400, the support part 120 can support the inner lid 400.

[0045] In one possible implementation, please continue to see Figure 4 and Figure 5 The opening of the receiving cavity 110 of the chopping cup 100 is partially recessed outward, so that the opening of the receiving cavity 110 forms a stepped structure, and the stepped surface of the stepped structure serves as the aforementioned support part 120.

[0046] In one embodiment, see Figures 3 to 5 The drive mechanism 520 is detachably connected to the transmission assembly. In actual use, the drive mechanism 520 can be removed first to separate it from the drive assembly, and then the first housing 310 can be separated from the chopping cup 100, further improving the safety of the chopper.

[0047] In one embodiment, the driving device includes a jog switch, which is electrically connected to the driving mechanism 520 and is used to control the driving mechanism 520. Specifically, the driving mechanism 520 is a motor.

[0048] In one embodiment, see Figures 3 to 6 The transmission assembly includes a first transmission member 511, and the tool holder assembly includes a tool holder 210. The tool holder 210 has a rotating shaft 211, one end of which is rotatably connected to the receiving cavity 110, and the other end of which is connected to the first transmission member 511. Specifically, the tool holder assembly includes a tool 220, which is mounted on the tool holder 210. The output end of the drive mechanism 520 is connected to the first transmission member 511. By driving the first transmission member 511 to rotate, the drive mechanism 520 can drive the rotating shaft 211 to rotate, thereby causing the rotating shaft 211 to drive the tool 220 to rotate and cut the material in the receiving cavity 110.

[0049] In this embodiment, the tool holder assembly includes a support shaft 230, which is installed at the bottom of the receiving cavity 110 and is used to rotate with the lower end of the rotating shaft 211.

[0050] In this embodiment, see Figures 3 to 6 The transmission assembly includes a gear assembly 512, and the housing assembly includes a first housing 310 and a second housing 320. The gear assembly 512 is disposed within the mounting cavity enclosed by the first housing 310 and the second housing 320. The gear assembly 512 is connected to the output end of the drive mechanism 520 via a rotating shaft and a coupling, and its lower end is fixedly connected to the first transmission member 511. Thus, by controlling the rotation of the drive mechanism 520, the first transmission member 511 can be driven to rotate, thereby causing the first transmission member 511 to drive the rotating shaft 211 of the tool holder assembly to rotate.

[0051] In one embodiment, see Figures 3 to 6 The transmission assembly includes a coupling joint 513, which is detachably connected to the first transmission member 511 and the rotating shaft 211. The coupling joint 513 has an axial portion 5131 and a first limiting portion 5132 and a second limiting portion 5133 spaced apart from the axial portion 5131. The axial portion 5131 engages with a clearance channel 410, and the inner cover 400 is located between the first limiting portion 5132 and the second limiting portion 5133. The connecting shaft head can rotate relative to the clearance channel 410 of the inner cover 400.

[0052] In one embodiment, see Figure 4 and Figure 6 The shredder also includes an interlocking assembly, which includes a first interlocking structure 610 and a second interlocking structure 620. The first interlocking structure 610 is disposed on the cavity wall of the receiving cavity 110, and the second interlocking structure 620 is disposed on the first housing 310. Rotating the first housing 310 can switch the second interlocking structure 620 and the first interlocking structure 610 between an engaged state and a disengaged state.

[0053] Specifically, when the first housing 310 is placed at the opening of the receiving cavity 110, the second interlocking structure 620 is aligned with the first interlocking structure 610. Then, when the first housing 310 is driven to rotate relative to the chopping cup 100 along the first direction, the second interlocking structure 620 and the first interlocking structure 610 can switch from a separated state to an engaged state. At this time, the first housing 310 cannot move axially along the rotation axis 211 of the blade holder assembly and cannot separate from the chopping cup 100. When it is necessary to separate the first housing 310 from the chopping cup 100, the first housing 310 is driven to rotate in the opposite direction of the first direction. At this time, the second interlocking structure 620 and the first interlocking structure 610 can switch from an engaged state to a separated state. At this time, the degree of freedom of the first housing 310 along the axial direction of the rotation axis 211 of the blade holder assembly is not constrained. By applying a force along the axial direction of the rotation axis 211 to the first housing 310, the first housing 310 can be separated from the chopping cup 100.

[0054] In one embodiment, please continue to refer to Figure 4 and Figure 6 The first interlocking structure 610 includes a circumferentially extending engagement groove, and the second interlocking structure 620 includes a protrusion that engages with the engagement groove. The engagement groove may be defined by a protrusion structure disposed on the inner wall of the receiving cavity 110, or it may be formed on the cup wall of the chopping cup 100.

[0055] In this embodiment, please continue to refer to Figure 4 and Figure 6 A meshing groove is formed on the wall of the chopping cup 100. A connecting channel is provided at one end of the chopping groove on the chopping cup 100. The connecting channel extends along the axial direction of the blade assembly. One end of the connecting channel connects to the chopping groove, and the other end connects to the outside. The protrusion can pass through the connecting channel until it is on the same plane as the chopping groove. Thus, when the first housing 310 and the chopping cup 100 need to be relatively fixed, the protrusion is aligned with the connecting channel. Then, the first housing 310 is moved along the axial direction of the rotation shaft 211 to a position flush with the chopping groove. The first housing 310 is then rotated, causing the protrusion to rotate from the connecting channel into the chopping groove. In this way, the first housing 310 cannot move along the direction of rotation of the rotation shaft 211, thereby achieving relative fixation of the first housing 310 and the chopping cup 100 in the axial direction of the rotation shaft 211. That is, the first housing 310 cannot be separated from the chopping cup 100 at this point.

[0056] In one application scenario, after the chopper is finished using it, the operator needs to position the chopping cup 100 with one hand and apply a rotational force to the first housing 310 with the other hand to open the first housing 310. Therefore, the user cannot simultaneously control the jog switch and drive the first housing 310 to rotate. In other words, when it is necessary to separate the first housing 310 from the chopping cup 100, neither of the user's hands can contact the jog switch. This avoids the situation where the operator accidentally touches the jog switch, causing the blade assembly to remain in a rotating state when the first housing 310 is opened. This solves the problem of accidentally injuring the operator who is removing food when the blade assembly is still in working state due to a failure to stop the blade.

[0057] In one embodiment, see Figures 4 to 6 The first housing 310 includes an abutment portion 311 and a mating portion 312. The mating portion 312 is disposed below the abutment portion 311, and there is a gap between the edges of the mating portion 312 and the abutment portion 311. The bottom of the abutment portion 311 abuts against the top of the chopping cup 100, and the mating portion 312 mates with the inner wall of the receiving cavity 110. In this way, the first housing 310 and the chopping cup 100 can be relatively fixed, reducing the possibility of the chopper being accidentally opened and causing injury to the operator from the blade holder assembly.

[0058] In one embodiment, see Figure 5 and Figure 6 The inner cover 400 is provided with a raised baffle 420, which is arranged in a ring shape, and the clearance channel 410 is located within the enclosure of the raised baffle 420.

[0059] In this embodiment, see Figure 6 The inner cover 400 has a recess 430, and a clearance channel 410 is provided in the recess 430. The recess 430 is recessed toward the bottom of the receiving cavity 110.

[0060] The shredder of this application is described in detail below with reference to a specific embodiment. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0061] See Figures 3 to 6 As shown, this embodiment includes a chopping cup 100, a blade holder 210, a first housing 310, a second housing 320, an inner cover 400, a first transmission component 511, a gear assembly 512, a coupling joint 513, and a drive mechanism 520.

[0062] The working principle of the shredder in this embodiment is as follows:

[0063] When in use, after placing the inner cover 400 into the chopping cup 100, the first housing 310 is interlocked with the chopping cup 100. During this process, the operator needs to hold the chopping cup 100 with one hand and the first housing 310 with the other hand and rotate the first housing 310 to fix the first housing 310 relative to the chopping cup 100. At this time, the operator's hands are not available to operate the jog switch. Therefore, the machine can only be started after the first housing 310 and the chopping cup 100 are interlocked, which helps to improve the safety performance of the machine. After the chopper is finished using it, separating the first housing 310 from the chopping cup 100 requires holding the chopping cup 100 with one hand and the first housing 310 with the other hand and rotating the first housing 310 to unlock it. Therefore, the operator must release the jog switch on the drive mechanism 520 when removing the first housing 310 from the chopping cup 100. This reduces the possibility that the blades 220 inside the chopping cup 100 will continue to rotate after the first housing 310 is removed, thereby improving the safety of using the chopper. After removing the first housing 310, the inner cover 400 needs to be removed before the food can be taken out. The inner cover 400 can further prevent the operator from being accidentally injured by the rotating blade assembly.
