Description

Technical Field

[0001] This utility model relates to the technical field of food processor blade structure, and in particular to a blade structure. Background Technology

[0002] With the improvement of living standards, household food processors have become an indispensable kitchen appliance in modern kitchens. They can perform various food processing functions such as meat cutting, vegetable chopping, food mixing, and egg beating, greatly simplifying the operation process of home cooking. Among the core working components of a food processor, the blade structure directly determines the processing efficiency and effect, while the connection structure between the blade and the drive mechanism is a key factor affecting the practicality, economy, and ease of storage of the device. Currently, existing household food processors typically feature multiple independent, dedicated blades to cater to different food processing needs. For example, the blade assembly for meat cutting consists of a cutting blade and an integrated, fixed blade shaft. The blade is welded to the blade shaft to form an inseparable whole. The blade assembly for egg beating consists of a beating plate and a dedicated blade shaft, with the shape of the beating plate and the dimensions of the blade shaft specifically designed for the egg beating function. In addition, blades for functions such as vegetable blending and nut grinding also adopt an integrated structure design of "processing workpiece + independent blade shaft". The existing structural design has several shortcomings that urgently need to be addressed: First, from a manufacturing perspective, each specialized tool requires a separately designed cutter shaft structure, which not only increases the cost of mold development but also leads to poor versatility in parts production. Cutter shafts for different tools cannot be shared, thus increasing overall manufacturing costs and hindering large-scale production. Second, from a user cost perspective, consumers need to purchase multiple complete tool assemblies to achieve various processing functions, each containing an independent cutter shaft, significantly increasing user purchase costs and reducing the product's market competitiveness. Finally, regarding storage convenience, multiple tool assemblies with their own cutter shafts require significant storage space due to the length and rigidity of the shafts, hindering efficient space utilization and causing inconvenience for daily storage. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a cutting tool structure.

[0004] A cutting tool structure designed for this purpose includes a shaft and a food processing element. On the peripheral wall of the shaft, multiple limiting ribs are arranged in a circumferential array; an assembly channel with an upper opening is formed between two adjacent limiting ribs. A locking element extending to the other limiting rib is provided on one of two adjacent limiting ribs; the locking element and the other adjacent limiting rib form an insertion port; The food processing element includes a cylinder sleeved on the outside of the shaft and a processing workpiece connected to the cylinder. On the inner wall of the cylinder, a plurality of locking blocks corresponding to the assembly channel are arranged in a circumferential array. The locking block can be inserted into the assembly channel from top to bottom and can pass through the insertion port; When the shaft rotates relative to the cylinder, the lower surface of the locking element abuts against the upper surface of the locking block, thereby constraining the locking block to move upward along the assembly channel.

[0005] Preferably, the upper end of the limiting rib is provided with a first guide slope extending inclinedly toward the assembly channel.

[0006] Preferably, the lower part of the assembly channel is provided with a limiting part that abuts against and limits the cylinder.

[0007] Preferably, the upper surface of the locking element is provided with a second guide slope that extends obliquely toward the insertion port.

[0008] Preferably, the food processing element is provided in a way that at least two food processing elements are stacked sequentially in the vertical direction; The number of locking elements corresponds to the number of food processing elements and they are arranged in a vertical direction.

[0009] Preferably, when at least two food processing elements are stacked and assembled, the lower cylinder is at least partially inserted into the upper cylinder, and the upper cylinder has an abutment portion that abuts and limits the upper surface of the lower cylinder.

[0010] Preferably, the lower surface of the shaft is provided with a positioning hole, and the upper end of the shaft is provided with an upwardly extending coupling shaft.

[0011] Preferably, the outer surface of the cylinder is provided with an anti-slip texture.

[0012] Preferably, the workpiece being processed is an egg beater.

[0013] Preferably, the workpiece being processed is a blade.

[0014] Compared with existing technologies, this utility model innovatively adopts a combined design of "shaft body + detachable food processing elements," breaking through the limitations of the existing integrated "one knife, one shaft" approach. The shaft body can serve as a universal basic component, adapting to different functional food processing elements (such as meat cutting blades, egg beaters, and mixing blades) through a circumferential array of limiting ribs and assembly channels. On the production side, there is no need to develop a dedicated cutting shaft for each processing element, reducing the number of molds and parts required, and lowering the cost of large-scale production. Users only need to purchase one universal shaft body and multiple sets of processing elements with different functions to meet various food processing needs, eliminating the need to repeatedly purchase complete knife assemblies with cutting shafts, significantly reducing user purchase costs and enhancing product market competitiveness. Meanwhile, since the food processing components and the shaft are detachable, the shaft and multiple processing components can be stored separately: longer shafts can be stored individually, while various processing components (such as the barrel + cutting blade, barrel + whisk) can be stacked or placed together in a smaller space due to their compact structure and lack of redundant shafts. Compared to existing knife assemblies with multiple independent shafts, this structure significantly reduces storage space requirements, solving the problem of "shafts taking up space and being difficult to organize" in traditional knife storage, and improving kitchen space utilization.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] See Figures 1-11 A cutting tool structure includes a shaft body 10 and a food processing element 20. Multiple limiting ribs 110 are arranged in a circumferential array on the peripheral wall of the shaft body 10. An assembly channel 100 with an upper opening is formed between adjacent limiting ribs 110. A locking element 120 extending towards the other limiting rib is provided on one of the adjacent limiting ribs 110. An insertion port 130 is formed between the locking element 120 and the adjacent limiting rib 110. The food processing element 20 includes components sleeved on the shaft body 10. The outer cylindrical body 210 and the processing workpiece 220 connected to the cylindrical body 210; on the inner wall of the cylindrical body 210, a plurality of locking blocks 230 corresponding to the assembly channel 100 are arranged in a circumferential array; the locking blocks 230 can be inserted into the assembly channel 100 from top to bottom and can pass through the insertion inlet 130; when the shaft 10 rotates relative to the cylindrical body 210, the lower surface of the locking element 120 can abut against the upper surface of the locking block 230, thereby constraining the locking block 230 to move upward along the assembly channel 100.

[0018] In this invention, the function switching of the blade structure is achieved through the detachable connection between the shaft 10 and the food processing element 20. The specific usage process and principle are as follows: First, align the food processing element 20 to be used (such as a cylinder 210 with a cutting blade / beating plate) with the shaft 10, so that the locking blocks 230 arranged in a circular array on the inner wall of the cylinder 210 correspond to the assembly channel 100 formed by adjacent limiting ribs 110 on the peripheral wall of the shaft 10. Next, fit the cylinder 210 over the outside of the shaft 10 from top to bottom, and insert the locking blocks 230 along the assembly channel 100 and through the insertion port 130 between the locking element 120 and another limiting rib 110. Finally, rotate the shaft 10 relative to the cylinder 210 in a first direction (the first direction is the rotation direction of the blade when in use). When the locking blocks 230 deviate from the original position of the assembly channel 100 with the rotation, the lower surface of the locking element 120 will abut tightly against the upper surface of the locking blocks 230, forming a reliable axial constraint and preventing the locking blocks 230 from coming off upward along the assembly channel 100. Meanwhile, the limiting rib 110 with locking element 120 can restrict the circumferential movement of locking block 230, further improving connection stability. Crucially, since the first direction is consistent with the rotation direction of the blade during operation, when the food processor drives the shaft 10 to rotate along the first direction to process ingredients (such as cutting or beating eggs), the rotation of the shaft 10 will keep the locking element 120 and the locking block 230 in contact, rather than causing them to separate. This eliminates the risk of the locking block 230 and the locking element 120 accidentally disengaging during the operation of the blade, ensuring a safe and stable processing process. The equipment can be started with confidence for processing. When it is necessary to change the processing function (such as switching from cutting meat to beating eggs), first turn off the equipment, remove the blade, and then rotate the shaft 10 relative to the cylinder 210 in a direction opposite to the first direction to allow the locking block 230 to rotate back to the position corresponding to the assembly channel 100, thereby releasing the axial constraint of the locking element 120 on the locking block 230; then lift the food processing element 20 upwards to allow the locking block 230 to disengage from the shaft 10 along the assembly channel 100 and the insertion port 130; then follow the above installation steps to lock the food processing element 20 with the newly processed workpiece 220 to the shaft 10, thereby realizing the function switch. The whole process does not require additional tools and is highly efficient and convenient to operate. See Figure 1 and Figure 6 The upper end of the limiting rib 110 is provided with a first guide slope 150 extending inclinedly towards the assembly channel 100. The core function of the first guide slope 150 is to provide assembly guidance for the locking block 230 of the food processing element 20: if there is a slight misalignment between the locking block 230 and the assembly channel 100 during installation, the first guide slope 150 can guide the locking block 230 to automatically correct its position through the inclined contact surface, and smoothly slide into the assembly channel 100 without repeated adjustments, reducing the difficulty of alignment and speeding up the installation.

[0019] See Figure 1 The upper surface of the locking element 120 is provided with a second guide slope 121 extending obliquely towards the insertion port 130. The core function of the second guide slope 121 is to assist the locking block 230 in smoothly passing through the insertion port 130: during installation, if there is a slight positional deviation between the locking block 230 and the locking element 120 during the downward movement, the second guide slope 121 can guide the locking block 230 to automatically adjust its path through the inclined contact surface, smoothly slide past the locking element 120 and enter below, avoiding jamming, further simplifying the installation operation and improving the smoothness of assembly.

[0020] See Figure 3 and Figure 5 The lower part of the assembly channel 100 is provided with a limiting part 140 that abuts against and limits the cylinder 210.

[0021] When a food processing element 20 is assembled, the limiting part 140 abuts against the cylinder 210 of the food processing element 20, thereby restricting the food processing element 20 to move downward.

[0022] When at least two food processing elements 20 are assembled, the at least two food processing elements 20 are stacked sequentially in the vertical direction; the number of locking elements 120 corresponds to the number of food processing elements 20 and they are arranged in the vertical direction. The limiting part 140 abuts against the cylinder 210 of the lowermost food processing element 20, thereby restricting the downward movement of that food processing element 20, while the other food processing elements 20 abut against each other sequentially in the vertical direction.

[0023] In this invention, when at least two food processing elements 20 are stacked and assembled, the lower cylinder 210 is at least partially inserted into the upper cylinder 210, and the upper cylinder 210 has an abutment portion 240 that abuts and limits the upper surface of the lower cylinder 210.

[0024] In this invention, a positioning hole 160 is provided on the lower surface of the shaft 10, and a coupling shaft 170 extending upward is provided on the upper end of the shaft 10. The positioning hole 160 is used for insertion and engagement with the positioning shaft of the food processor cup, while the coupling shaft 170 is used to connect to the driver to achieve a transmission connection.

[0025] In this invention, the outer surface of the cylinder 210 is provided with an anti-slip texture.

[0026] In this invention, the processing workpiece 220 is a beater or a blade, or other existing workpieces used for processing food ingredients.
