Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a cutter head module and a cooking machine applying the same. Background Art

[0002] A cooking machine integrates functions such as making soymilk, grinding dry powder, squeezing juice, making minced meat, and shaving ice, and is a household appliance used for making various foods such as juice, soymilk, jam, dry powder, shaved ice, and minced meat. It is a product after the juicer becomes more diversified.

[0003] For easy cleaning, most of the existing knives in cooking machines are designed to be detachable. For example, CN220369899U "Stirring Knife Assembly and Cooking Machine" discloses a detachable knife assembly structure. Although this structure realizes the detachable function of the knife assembly, this structure has the problem that the blade is likely to fall off and fly out under the action of inertia, and due to the unstable installation structure of the knife, the vibration is large during high-speed operation, resulting in excessive noise.

[0038] Through the above settings, it is ensured that the cutter 3 can rotate only on the premise of forming sufficient transmission cooperation with the rotating shaft 2. Once the cutter 3 is disengaged, the transmission cooperation will be released, so that the cutter 3 will not continue to rotate at high speed under the action of the rotating shaft 2 when disengaged, eliminating the danger brought by the high-speed flying of the cutter 3 and greatly protecting the user's safety in use.

[0039] Specifically, the limiting platform includes a first limiting platform 31, the first limiting platform 31 is provided at one end of the cutter 3 away from the cutter head 1, the limiting structure includes a first limiting portion 21, and the first limiting portion 21 is provided at one end of the rotating shaft 2 away from the cutter head 1; more specifically, the limiting platform includes a second limiting platform 32, the second limiting platform 32 is provided at one end of the cutter 3 close to the cutter head 1, the limiting structure includes a second limiting portion 22, and the second limiting portion 22 is provided on the outer peripheral side of the rotating shaft 2 corresponding to the second limiting platform 32; wherein, the first limiting platform 31 and the second limiting platform 32 can be selectively provided or provided simultaneously, and correspondingly, the first limiting portion 21 and the second limiting portion 22 can also be selectively provided or provided simultaneously.

[0040] Further, the clamping portion 33 is arranged inside one end of the duct close to the cutter head 1; furthermore, the height H1 of the mating portion 23 along the axial direction of the rotating shaft 2 is ≥ 3 mm, that is, H1 ≥ 3 mm, to prevent the mating area between the clamping portion 33 and the mating portion 23 from being too small and affecting the normal transmission between the rotating shaft 2 and the cutter 3; optionally, the clamping portion 33 is arranged in a square hole shape, and four groups of mating portions 23 corresponding to the clamping portion 33 are evenly distributed on the outer peripheral side of the rotating shaft 2, so that a more stable transmission connection is formed between the cutter 3 and the rotating shaft 2; in addition, the clamping portion 33 can also be arranged as a hexagonal or square hole with rounded corners, and hole shapes with the number of sides not less than four should also be covered by the present utility model; in addition, the clamping portion 33 can also be arranged as a triangular hole, and correspondingly, three groups of mating portions 23 corresponding to the clamping portion 33 are evenly distributed on the outer peripheral side of the rotating shaft 2.

[0041] Preferably, the rotating shaft 2 is provided with a shaft portion 20 corresponding to the duct, and the rotating shaft 2 is matched with the cutter 3 through the shaft portion 20 being matched with the duct, so as to form a positioning fit between the rotating shaft 2 and the cutter 3, and the fit clearance between the shaft portion 20 and the duct is preferably 0.03 - 0.1 mm, so as to leave a certain error clearance on the premise of ensuring the stable connection between the rotating shaft 2 and the cutter 3, and improve the yield rate of production; more preferably, the ratio of the height H2 of the shaft portion 20 along the axis of the rotating shaft 2 to the height H1 of the mating portion 23 along the axial direction of the rotating shaft 2 is greater than or equal to 5 and less than or equal to 10, that is, 5 ≤ H2 / H1 ≤ 10, so as to avoid; in practical applications, the diameter length of the first limiting portion 21 is equal to the diameter length of the shaft portion 20, and the diameter length of the second limiting portion 22 is greater than the diameter length of the shaft portion 20.

[0042] Actually, one end of the cutter 3 far from the cutter head 1 penetrates through to the duct to form a guiding hole 34, and one end of the rotating shaft 2 far from the cutter head 1 is provided with a guiding portion 24 corresponding to the guiding hole 34. When the cutter 3 is matched with the rotating shaft 2, the guiding portion 24 is matched inside the guiding hole 34. When the rotating shaft 2 rotates, it can ensure that the rotating direction of the cutter 3 and the rotating direction of the rotating shaft 2 are on the same axis; wherein, the diameter length of the guiding portion 24 is smaller than the diameter length of the first limiting portion 21, and the first limiting portion 21 is arranged around the guiding portion 24 at one end of the cutter 3 far from the cutter head 1.
