Description

Technical Field

[0001] This utility model relates to the technical field of food shredders, and in particular to a labor-saving food shredder. Background Technology

[0002] Currently common food choppers on the market, such as the multi-functional hand-operated vegetable chopper disclosed in Chinese Patent Publication No. CN202640401U, include a box body and a pressure plate hinged to the end of the box body via a pin. The box body has a cavity, and a lid is provided at the top of the box body. A blade assembly is provided on the lid, and a pressing mold part with several protrusions is provided on the pressure plate corresponding to the position of the blade assembly. The pressure plate can rotate between a cutting position near the blade assembly and an open position away from the blade assembly. In the cutting position, the food is chopped by the cooperation of the blade assembly and the pressing mold part. However, existing food choppers require a greater force to be applied to the pressure plate to chop the food, which is laborious to operate and makes the operator more prone to fatigue. Therefore, improvements to existing food choppers are needed. Utility Model Content

[0003] The purpose of this invention is to provide a labor-saving food chopper. By designing the connection structure between the pressure plate, the pressure block and the box body, the pressure plate and the pressure block form a composite lever mechanism, thereby enabling more labor-saving food chopping.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a labor-saving food chopper, comprising...

[0005] The box body has a knife installed on it, and a hinge seat is installed at the rear end of the box body;

[0006] The pressure plate has a connecting end and a free end. The connecting end of the pressure plate is pivotally connected to the hinge seat of the box body so that the pressure plate can rotate relative to the hinge seat.

[0007] The pressure block has one end pivotally connected to the hinge seat so that the pressure block can rotate relative to the hinge seat, and the other end of the pressure block is movably connected to the pressure plate through the connecting arm. The pressure block is provided with a pressing mold part.

[0008] The pressure plate, pressure block, and connecting arm work together to form a force-saving composite lever mechanism;

[0009] When the pressure plate rotates relative to the hinge seat toward the direction of the blade, the pressure plate acts on the pressing mold part through the compound lever mechanism, so that the pressing mold part cooperates with the blade to cut the food.

[0010] Furthermore, the hinge seat has a rotation space, and the end of the pressure block that is pivotally connected to the hinge seat is disposed within the rotation space.

[0011] Furthermore, the hinge seat is formed as a left lug and a right lug on the rear end of the box body, and the rotation space is formed between the left lug and the right lug. The connecting end of the pressure plate is provided with a left bracket and a right bracket. The left bracket is hinged to the outer end of the left lug, and the right bracket is hinged to the outer end of the right lug.

[0012] Furthermore, the connecting arms are provided in two sets and symmetrically arranged on both sides of the pressure block. The connecting arm on the left side is located between the left support and the pressure block, and the connecting arm on the right side is located between the right support and the pressure block.

[0013] Furthermore, the connecting arm has an L-shaped structure or a near-L-shaped structure.

[0018] Furthermore, the molding part is fastened to the pressing block, the back of the molding part is fitted to the front of the pressing block, one end of the molding part has a positioning groove, the other end of the molding part has a buckle, and the pressing block has a positioning protrusion that cooperates with the positioning groove and a corresponding groove that cooperates with the buckle.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This food chopper, through its redesigned connection structure between the pressure plate, pressure block, and box body, forms a labor-saving composite lever mechanism with the pressure plate, pressure block, and connecting arm, thus enabling more labor-saving food chopping. Specifically, the area between the free end of the pressure plate and the connecting piece a of the pressure plate constitutes the force-applying axis, the area between the corresponding connecting pieces a and c constitutes the force-bearing rotation axis, and the connecting piece d at the pressure block is the force-bearing point. The force at the force-bearing point is equal to the force at the force-applying point multiplied by (force-applying axis / length of the force-bearing rotation axis). By improving the connection structure between the pressure plate, pressure block, and box body, the length of the force-bearing rotation axis can be effectively shortened, resulting in better labor-saving performance.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-7 As shown, a labor-saving food chopper includes a box body 10, a pressure plate 30, a pressure block 40, and a connecting arm 50, which constitute the technical structure of this utility model.

[0031] The box body 10 is provided with a cutter 20, and the rear end of the box body 10 is provided with a hinge seat 11; the pressure plate 30 has a connecting end and a free end, the connecting end of the pressure plate 30 is pivotally connected to the hinge seat 11 of the box body 10 so that the pressure plate 30 can rotate relative to the hinge seat 11; one end of the pressure block 40 is pivotally connected to the hinge seat 11 so that the pressure block 40 can rotate relative to the hinge seat 11, and the other end of the pressure block 40 is movably connected to the pressure plate 30 through a connecting arm 50. The pressure block 40 is provided with a pressing mold part 41; the pressure plate 30, the pressure block 40 and the connecting arm 50 cooperate to form a force-saving composite lever mechanism.

[0032] When the pressure plate 30 rotates relative to the hinge seat 11 toward the direction of the blade 20, the pressure plate 30 acts on the pressing mold part 41 through the compound lever mechanism, so that the pressing mold part 41 cooperates with the blade 20 to cut the food.

[0033] In some embodiments, the hinge seat 11 forms a rotation space 12, and one end of the pressure block 40, which is pivotally connected to the hinge seat 11, is disposed in the rotation space 12. Specifically, one end of the pressure block 40 is pivotally connected to the hinge seat 11 of the housing 10 via a connector b42, and the other end of the pressure block 40 is pivotally connected to the connecting arm 50 via a connector d52. The pressing part 41 is disposed at the other end of the pressure block 40 relative to the hinge seat 11.

[0034] In some embodiments, the connecting end of the pressure plate 30 is pivotally connected to the hinge seat 11 of the box body 10 via the connector a31, and the connecting arm 50 is pivotally connected to the pressure plate 30 via the connector c51. The area of ​​the pressure plate 30 corresponding to the connector a31 and the connector c51 forms a force-bearing pivot.

[0035] The free end of the pressure plate 30 is the user's force application point. The area between the force application point and the connector a31 of the pressure plate 30 forms the force application axis. The area between the connector a31 and the connector c51 of the pressure plate 30 forms the force-bearing axis. The connector d52 at the pressure block 40 is the force-bearing point. The force on the force-bearing point = the force of the force application point * (force application axis / length of the force-bearing axis). By improving the connection structure between the pressure plate 30, the pressure block 40 and the box 10, the length of the force-bearing axis can be effectively shortened, resulting in better force-saving effect. The straight distance between the connector c51 and the connector d52 at both ends of the connecting arm 50 forms the force transmission axis. The force transmission axis only transmits force and does not increase or decrease force.

[0036] In some embodiments, the hinge seat 11 is a left lug 111 and a right lug 112 formed on the rear end of the box body 10. The left lug 111 and the right lug 112 protrude upward on the upper end surface of the box body 10. The rotation space 12 is formed between the left lug 111 and the right lug 112. The connecting end of the pressure plate 30 is provided with a left support 32 and a right support 33. The left support 32 is hinged to the outer end of the left lug 111, and the right support 33 is hinged to the outer end of the right lug 112. This arrangement can avoid the rotational movement space of the pressure block 40 so that the pressure block 40 can rotate smoothly in the rotation space 12.

[0037] In some embodiments, the connecting arms 50 are provided in two sets and symmetrically arranged on both sides of the pressure block 40. The connecting arm 50 on the left is located between the left support 32 and the pressure block 40, and the connecting arm 50 on the right is located between the right support 33 and the pressure block 40. Specifically, the first end of the left connecting arm 50 is pivotally connected to the left support 32 via connector c51, and the second end of the left connecting arm 50 is pivotally connected to the second end of the pressure block 40 via connector d52. The first end of the right connecting arm 50 is pivotally connected to the right support 33 via connector c51, and the second end of the right connecting arm 50 is pivotally connected to the second end of the pressure block 40 via connector d52. By providing two sets of connecting arms 50, the force applied at the point of application can be transmitted to the point of application more smoothly, which not only improves the chopping efficiency but also extends the service life.

[0038] In some embodiments, the connecting arm 50 is an L-shaped structure or a near-L-shaped structure. This configuration makes the structure more compact and allows for better transmission of the force from the pressure plate 30 to the pressure block 40.

[0039] In some embodiments, the box body 10 includes a box body 13 having a receiving cavity and a box cover 14 covering the box body 13. The box cover 14 has an annular groove 141 communicating with the receiving cavity. The cutter 20 is disposed in the annular groove 141. A stepped surface is formed at the inner end of the annular groove 141, and the cutter 20 is supported by the stepped surface. Specifically, the cutter 20 includes a retainer 21 arranged in an annular shape and a grid cutter mesh 22 disposed in the retainer 21.

[0040] In some embodiments, the cutter 20 has a grid cutter mesh 22, and the die part 41 has a unit die column that cooperates with the mesh openings of the grid cutter mesh 22. The die part 41 cooperates with the grid cutter mesh 22 to cut the material into thin strips.

[0041] In some embodiments, the lid 14 is inclined downward relative to the box body 13 from the rear to the front horizontal plane, so that when the cutter 20 is installed on the lid 14, the cutter 20 is inclined accordingly. Compared with the horizontal setting, the inclined setting can save more effort.

[0042] In some embodiments, the housing 10 is provided with a recess 142 at the position corresponding to the tool 20, which facilitates the assembly and disassembly of the tool 20.

[0043] In some embodiments, the molding part 41 is detachably connected to the pressing block 40. This configuration allows the molding part 41 to be removed from the pressing block 40 to remove food residues adhering to the molding part 41, thereby effectively keeping the molding part 41 clean.

[0044] Specifically, the molding part 41 is fastened to the pressing block 40, and the back of the molding part 41 is fitted to the front of the pressing block 40. One end of the molding part 41 has a positioning groove 411, and the other end of the molding part 41 has a buckle 412. The pressing block 40 is provided with a positioning protrusion 43 that cooperates with the positioning groove 411 and a corresponding groove 44 that cooperates with the buckle 412.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
