[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0034] This application discloses a shredder, including a support 100; a shredding panel 200 is provided at the front of the support 100; a shredding panel 300 is provided at the rear of the support 100; a shredding blade 400 is provided on the side of the shredding panel 200 facing the shredding panel 300; a shredding blade 500 is installed on the end of the shredding panel 300 facing the shredding panel 200; wherein, a discharge port 110 is formed between the shredding blade 400 and the shredding blade 500; the shredding panel 300 is connected to a lifting device 600, and the lifting device 600 can control the shredding panel 300 to rise and fall along the height direction.

[0035] In this embodiment, the support 100 is equipped with both a shredder panel 200 and a shredder panel 300. For example, during use, the object to be shredded first passes through the shredder 400 to control the width of the shreds, and then passes through the shredder 500 to control the thickness of the shreds. It can also be understood that the shredder 400 and the shredder 500 control the length and width of the shreds respectively. After being shredded by the shredder 500, the shreds fall from the discharge port 110 for collection. When it is necessary to control the thickness of the shreds, the shredder panel 300 and the shredder 500 on it are raised by the lifting device 600, which increases the thickness of the shreds. The shredder panel 300 and the shredder 500 on it are lowered by the lifting device 600, which decreases the thickness of the shreds. This meets different usage needs and does not require replacing the blades, making the operation more convenient and faster.

[0036] The height direction can be understood as follows: Figure 1 The thickness direction of the grater shown is perpendicular to the surface of the grater panel 200.

[0037] Optionally, the bottom of the support 100 may be provided with an opening corresponding to the discharge port 110 to facilitate the falling of shredded material; alternatively, the support 100 may have a cavity inside for receiving the shredded material, and an opening at one end of the support 100, so that the shredded material can be poured out from the opening at one end of the support 100 after shredding.

[0038] like Figure 1-5 In an optional or preferred embodiment, the lifting device 600 is located directly below the shredding panel 300; the lifting device 600 includes a first lead screw nut sliding mechanism mounted on the bracket 100, the first lead screw nut sliding mechanism includes a first rotating member 610 and a first sliding member 620 threadedly fitted onto the first rotating member 610; the first rotating member 610 is arranged along the height direction; the first sliding member 620 is connected to the shredding panel 300.

[0039] In this embodiment, the lifting device 600 is a spiral lifting mechanism that utilizes the working principle of a lead screw and nut sliding mechanism. By rotating the first rotating member 610, the first sliding member 620, which is threaded onto the first rotating member 610, rises or falls, thereby driving the shredding panel 300 and the shredding cutter 500 to rise and fall.

[0040] In an optional or preferred embodiment, the first rotating member 610 is configured to be rotatably connected to the first threaded member of the bracket 100; the first sliding member 620 includes a first threaded block 621 that is threadedly engaged with the first threaded member, and a first linear sliding assembly 622 that connects the bracket 100 and the shredding panel 300; the first threaded block 621 is connected to the shredding panel 300.

[0041] In this embodiment, when the first threaded component rotates, since the first threaded block 621 is connected to the shredding panel 300, and the shredding panel 300 is connected to the bracket 100 through the first linear sliding component 622, the shredding panel 300 and the first threaded block 621 can only move up and down. Thus, the rotational movement of the first threaded component can control the shredding panel 300 and the shredding cutter 500 to move up and down.

[0042] In an optional or preferred embodiment, the bracket 100, the shredder panel 200, and the shredder panel 300 surround and form a mounting cavity 120. The first rotating member 610 passes through the mounting cavity 120 toward the bottom of the bracket 100, thereby facilitating direct control of the first rotating member 610 by the user. Preferably, a rotating handle can be provided at the outer end of the first rotating member 610 for easy gripping and use.

[0043] like Figure 6-8 In an optional or preferred embodiment, the lifting device 600 is disposed below the shredding panel 300; the lifting device 600 includes a second lead screw nut sliding mechanism and an inclined plane drive mechanism 630, the second lead screw nut sliding mechanism includes a second rotating member 640 and a second sliding member 650 threadedly sleeved on the second rotating member 640, wherein the second rotating member 640 extends horizontally; the second sliding member 650 is horizontally slidably connected to the bracket 100, and the second sliding member 650 is connected to the shredding panel 300 through the inclined plane drive mechanism 630 to drive the shredding panel 300 to lift.

[0044] In this embodiment, the second rotating member 640 in the second lead screw nut sliding mechanism extends horizontally, and the second sliding member 650 is horizontally slidably connected to the bracket 100. Thus, the rotation of the second rotating member 640 can drive the second sliding member 650 to slide horizontally along the bracket 100. At the same time, the second sliding member 650 is connected to the shredding panel 300 through the inclined plane drive mechanism 630. Therefore, when the second sliding member 650 moves horizontally, the inclined plane drive mechanism 630 can drive the shredding panel 300 and the shredding cutter 500 to move up and down.

[0045] In an optional or preferred embodiment, the second rotating member 640 is configured as a second threaded member; the second sliding member 650 includes a second threaded block 651 that is threadedly engaged with the second threaded member and a second linear sliding assembly 652, the second threaded block 651 being connected to the bracket 100 via the second linear sliding assembly 652; the inclined plane driving mechanism 630 includes a first wedge 631 and a second wedge 632 that are inclinedly engaged with each other, the first wedge 631 being connected to the second threaded block 651; and the second wedge 632 being connected to the shredding panel 300.

[0046] In this embodiment, the second threaded component is rotated to drive the second threaded block 651 and the first wedge 631 to move in the horizontal direction. The first wedge 631 drives the second wedge 632 to rise or fall through the inclined surface engagement, thereby driving the shredding panel 300 and the shredding cutter 500 to rise and fall.

[0047] In an optional or preferred embodiment, the first wedge 631 and the second wedge 632 have oppositely arranged inclined surfaces and the two inclined surfaces are connected by a third linear sliding assembly 660, the sliding direction of the third linear sliding assembly 660 being the extension direction of the inclined surfaces.

[0048] In this embodiment, the two inclined surfaces of the first wedge 631 and the second wedge 632 are connected by a third linear sliding assembly 660. In this way, while the first wedge 631 can drive the second wedge 632 to rise and fall, the position of the second wedge 632 and the slicing panel 300 can be locked, so that the slicing panel 300 and the second wedge 632 will not move due to, for example, collision with the slicing blade 500 when an object is slicing.

[0049] In an optional or preferred embodiment, the two inclined surfaces of the first wedge 631 and the second wedge 632 are in rolling contact to facilitate relative movement between them. The rolling contact may be provided, for example, with a groove between them, in which a rolling shaft is rotatably disposed, and the rolling shaft protrudes from the groove.

[0050] In an optional or preferred embodiment, the second linear sliding component 652 is a mortise and tenon structure, and / or the third linear sliding component 660 is a mortise and tenon structure. The mortise and tenon structure has strong stability and good shock resistance, making the product more efficient and stable when used for slicing. The mortise and tenon structure can be, for example, a dovetail slide rail structure, a straight tenon slide rail structure, or a sleeve fit between a cylinder and a curved tube.

[0051] In an optional or preferred embodiment, the bracket 100, the shredder panel 200, and the shredder panel 300 surround and form a mounting cavity 120, and the second rotating member 640 passes through the mounting cavity 120 toward the end of the bracket 100.

[0052] In this embodiment, the second rotating member 640 passes through the mounting cavity 120 at its end toward the bracket 100, facilitating a user's screwing operation, such as... Figure 6 As shown, the second rotating member 640 passes through the rear end of the bracket 100, which is the rear area where the shredding panel 300 is located.

[0053] It should be understood that the bracket 100, the shredder panel 200 and the shredder panel 300 surround and form the mounting cavity 120. The control end of the lifting device 600 passes through the mounting cavity 120 to facilitate operation of the control end. The control end can be understood as the first rotating member 610 and the second rotating member 640.

[0054] In an optional or preferred embodiment, the shaving cutter 400 includes a shaving shaft 410 rotatably connected to and lockable on the bracket 100. A plurality of shaving blade groups 420 are arranged in a ring on the shaving shaft 410. Each shaving blade group 420 includes a plurality of shaving blades 421 spaced apart along the extension direction of the shaving shaft 410. The spacing between adjacent shaving blades 421 of at least two shaving blade groups 420 is different.

[0055] In this embodiment, such as Figure 1 , 4 As shown, the shaving shaft 410 is arranged along the width direction of the support 100 and is rotatable. Multiple shaving blade groups 420 are arranged in a ring on the shaving shaft 410. Each time the shaft rotates by a preset angle, a set of shaving blade groups 420 is replaced to perform the shaving operation. The spacing between adjacent shaving blades 421 on at least two shaving blade groups 420 is different. Therefore, by rotating the shaving shaft 410 to change different shaving blade groups 420 facing upwards, the width of the shreds can be controlled. In conjunction with the shredding cutter 500, the thickness of the shreds can be controlled, thereby achieving more precise control over the thickness of the shreds. Preferably, there are four sets of shaving blade groups 420, with each set arranged at a 90° angle to the others.

[0056] In an optional or preferred embodiment, the shaving panel 200 is slidably connected to the bracket 100 in the horizontal direction; a limiting groove 210 is provided on the side of the shaving panel 200 facing the shaving cutter 400, and the limiting groove 210 can be engaged with any shaving cutter assembly 420.

[0057] In this embodiment, the shaving panel 200 is slidably connected to the bracket 100 in the horizontal direction, and a limiting groove 210 is provided on the side of the shaving panel 200 facing the shaving cutter 400. The limiting groove 210 engages one of the shaving cutter sets 420, thereby locking the shaving shaft 410. In use, the shaving panel 200 is moved away from the shaving cutter 400, and the limiting groove 210 releases the engagement of the shaving cutter set 420, thereby unlocking the shaving shaft 410. By rotating the shaving shaft 410, another shaving cutter set 420 is replaced and used for shaving. Then, the shaving panel 200 is reset and the limiting groove 210 locks the shaving cutter set 420.

[0058] Optionally, the shredder panel 200 is connected to the bracket 100 by a snap-fit ​​structure 130 to position the shredder panel 200 on the bracket 100; the snap-fit ​​structure 130 can be, for example, an elastic snap-fit, so that the shredder panel 200 can be translated on the bracket 100 when it needs to be subjected to a certain external force.

[0059] Optionally, the shaving panel 200 and the bracket 100 are connected by an elastic reset member so that the shaving panel 200 can automatically reset after translation.

[0060] Optionally, the end of the shaving panel 200 away from the shaving blade 400 is provided with a handle for easy gripping and use.

[0061] Optionally, the end of the shaving spindle 410 passes through the bracket 100 and extends out to facilitate its operation.

[0062] Optionally, the cross-section of the limiting groove 210 is adapted to the shape of the shaving blade 421.

[0063] Optionally, the cross-section of the limiting groove 210 is V-shaped.

[0064] A set of flat portions 460 extending axially along the outer side of the shaving shaft 410 is provided, thereby enabling the present application to perform the work of slicing only. It is understood that the arrangement of the flat portions 460 here is for demonstration purposes and should not be regarded as a limitation, with the aim of enabling it to perform the action of slicing only. Preferably, with the shaving shaft 410 as the center, a shaving blade assembly 420 is provided opposite to the flat portions 460 to facilitate locking.

[0065] In an optional or preferred embodiment, the shaving panel 200 and the shaving shaft 410 are connected by a one-way intermittent transmission mechanism, so that when the shaving panel 200 moves forward, it drives the shaving shaft 410 to rotate by a preset angle, and when the shaving panel 200 moves backward, it does not drive the shaving shaft 410 to rotate. For example, when the shaving panel 200 moves away from the shaving shaft 410, the shaving panel 200 drives the shaving shaft 410 to rotate by a preset angle through the one-way intermittent transmission mechanism, so that the other set of shaving blades 420 or the flat part 460 faces upward. Then, the shaving panel 200 moves closer to the shaving shaft 410 until it returns to its original position, during which time it does not drive the shaving shaft 410 to rotate. Since it has returned to its original position, if the shaving panel 200 moves away from the shaving shaft 410 again, it can drive the shaving shaft 410 to rotate again, thereby completing the one-way intermittent transmission. As for the specific structure, there are many variations, mainly for protection and coordination with other designs.

[0066] In one preferred embodiment, the first end of the shaving shaft 410 is connected to a gear 440, and the shaving panel 200 is provided with a rack 450 corresponding to the gear 440. The rack 450 is connected to the gear 440 in one direction, thereby enabling the shaving panel 200 to drive the gear 440 to rotate a certain angle when the rack 450 moves in the forward direction, and not to drive the gear 440 to move when it moves in the reverse direction; for example Figure 9As shown, multiple stop portions 411 are fixedly arranged in a ring on the first end face of the shaving shaft 410. A gear 440 is rotatably connected to the shaving shaft 410. A pushing portion 441 is fixedly arranged on the outer side of the gear 440 corresponding to the stop portion 411. There is a gap between two adjacent stop portions 411 for the pushing portion 441 to rotate. That is, when the shaving panel 200 moves forward, the rack 450 drives the gear 440 and the pushing portion 441 to rotate, thereby pushing the stop portion 411 and the shaving shaft 410 to rotate. When the shaving panel 200 moves in the reverse direction, the rack 450 and the pushing portion 441 rotate back to their original positions and do not drive the shaving shaft 410. For example, the teeth of the rack 450 are unidirectional rotating teeth, and the gear 440 is fixedly connected to the shaving shaft 410, so that the rack can drive the gear 440 to rotate when moving forward, but cannot drive the gear 440 when moving in the reverse direction.

[0067] In one preferred embodiment, the second end of the shaving shaft 410 is provided with a ratchet positioning mechanism 430 to match the single rotation angle of the first end of the shaving shaft 410; for example, the ratchet is fixed by a torsion spring, thereby ensuring that the shaving shaft 410 can be positioned after each rotation. As for the specific structural fit, it is the prior art and will not be described in detail.

[0068] In an optional or preferred embodiment, a hand guard 700 is slidably provided on the top of the support 100, the hand guard 700 being able to hold an object and bring the object close to the shredder panel 200 or the slicing panel 300 [1].
