Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a cutter head assembly. Background Art

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

[0034] Embodiment 1

[0035] According to Figures 1 to 10 As shown, this utility model provides an embodiment of a cutter head assembly, including: a cutter head 1, a rotating shaft 2, and a cutter 3.

[0036] Among them, the rotating shaft 2 is rotatably installed on the cutter head 1. A clamping structure 21 is arranged on the circumferential side of the end of the rotating shaft 2 far from the cutter head 1, and the end of the rotating shaft 2 far from the cutter head 1 is the top end of the rotating shaft 2; a hole is correspondingly arranged in the cutter 3 for the rotating shaft 2, and a clamping part 311 is arranged in the hole, and the clamping part 311 can undergo elastic deformation; when the rotating shaft 2 is inserted into the hole, by applying a downward pressure to the cutter 3, the clamping part 311 undergoes elastic deformation under the relative pressure of the rotating shaft 2, so that the clamping structure 21 is clamped with the clamping part 311, so that the rotating shaft 2 is connected to the cutter 3.

[0037] Through the above settings, the stable detachable connection between the rotating shaft 2 and the cutter 3 is realized, the phenomenon of flying cutter caused by the cutter 3 falling off during high-speed rotation is avoided, the safety of users is ensured, and correspondingly, the problem of vibration and noise caused by the insufficient firm connection between the cutter 3 and the rotating shaft 2 is also overcome.

[0038] Specifically, the clamping structure 21 includes a clamping groove, and the clamping part 311 is provided with a clamping rib 312 corresponding to the clamping groove, so that the clamping rib 312 is clamped in the clamping groove, so that the rotating shaft 2 is firmly connected to the cutter 3; more specifically, the outer diameter D2 of the end of the rotating shaft 2 far from the cutter head 1 is greater than the inner diameter D1 of the clamping part 311 corresponding to the clamping rib 312. When the clamping rib 312 is clamped in the clamping groove, a stable clamping relationship can be formed between the clamping part 311 and the rotating shaft 2.

[0039] Furthermore, a through hole 34 communicating with the hole is arranged at the end of the cutter 3 far from the cutter head 1. An abutting platform 33 is formed by the inward extension of the through hole 34. An abutting part 22 is arranged at the end of the rotating shaft 2 far from the cutter head 1. When the rotating shaft 2 is connected to the cutter 3, the abutting part 22 abuts against the abutting platform 33 to limit the cutter 3 from approaching the cutter head 1 excessively, and avoid interference between the blade 35 on the cutter 3 and the cutter head 1 during rotation, so as to damage the cutter 3 and scratch the cutter head 1, and ensure the safe use of users; furthermore, the distance between the middle of the clamping groove and the abutting part 22 is equal to the distance between the middle of the clamping rib 312 and the abutting platform 33, so that the abutting part 22 abuts against the abutting platform 33 after the clamping rib 312 and the clamping groove are clamped, and avoid leaving a gap between the abutting part 22 and the abutting platform 33 and being unable to form an abutting limit structure.

[0040] Preferably, a mating seat is provided at one end of the tool 3 facing the cutter head 1, and a mating portion 23 is provided on the rotating shaft 2 corresponding to the mating seat. When the rotating shaft 2 is connected to the tool 3, the inner wall of the mating seat cooperates with the mating portion 23, so that the rotating shaft 2 and the tool 3 form a power connection, enabling the tool 3 to rotate with the rotation of the rotating shaft 2; wherein, the thickness L2 of the mating seat is L2≧2mm, to avoid being too thin and affecting the sufficient mating area to ensure the normal transmission between the rotating shaft 2 and the tool 3; more preferably, the distance L1 between the middle of the clamping groove and the abutting portion 22 is greater than or equal to the height H1 of the overlapping part of the inner wall of the mating seat and the mating portion 23, to ensure that the inner wall of the mating seat and the mating portion 23 can form a fit only after the clamping rib 312 is clamped with the clamping groove, achieving the effect of ensuring user safety.

[0041] Specifically, as Figures 4 to 5 shown, when L1 is greater than H1, the tool group is sleeved on the rotating shaft 2 through the hole. If no downward pressure is applied to the tool 3 at this time, since D2 is greater than D1, the clamping rib 312 will abut against the abutting portion 22 and fail to be clamped with the clamping groove. Correspondingly, the inner wall of the mating seat also fails to cooperate with the mating portion 23. Therefore, even if the rotating shaft 2 rotates at this time, it cannot drive the tool 3 to rotate, which can eliminate the hidden danger of flying knives when the user forgets to press the tool 3, thus playing a role in ensuring user safety; as Figures 6 to 7 shown, when the user presses the tool 3, the clamping member 311 undergoes elastic deformation under the relative pressure of the rotating shaft 2, so that the clamping groove is clamped with the clamping member 311, and the inner wall of the mating seat cooperates with the mating portion 23, and then the rotating shaft 2 is connected to the tool 3. At this time, the tool 3 is completely engaged with the rotating shaft 2, and the clamping rib 312 is also completely locked in the clamping groove to eliminate the risk of the tool 3 disengaging during rotation; correspondingly, when the user needs to disassemble the tool 3, directly applying an upward pressure to the tool 3 can cause the clamping member 311 to deform under the relative pressure of the clamping rib 312, and the clamping rib 312 is disengaged from the clamping groove, so that the tool 3 is separated from the rotating shaft 2.

[0042] More preferably, a concave ring 313 is formed on the outer peripheral side of the snap-in member 311, so as to leave a deformation space between the snap-in member 311 and the inner wall of the hole, providing sufficient space for the snap-in member 311 to accommodate the deformation amount when it undergoes elastic deformation; in practical applications, an installation space is formed in the hole, and the snap-in member 311 is arranged in the installation space; actually, the cutter 3 includes a tool holder 31 and a tool cover 32, the hole is arranged in the tool holder 31, the installation space is arranged at one end of the hole close to the tool cover 32, and the tool cover 32 is installed on the tool holder 31, so that the snap-in member 311 is fixed in the installation space; optionally, the rotating shaft 2 includes a shaft portion 20, and the rotating shaft 2 is connected to the cutter 3 by inserting the shaft portion 20 into the hole, and the shaft portion 20 is arranged between the snap-in structure 21 and the mating portion 23; in addition, a driving portion 25 is formed on the circumferential side of the bottom end of the rotating shaft 2 to form a driving connection with the driving source so that the rotating shaft 2 rotates under the action of the driving source; furthermore, a guiding portion 24 can be arranged at the top end of the rotating shaft 2. When the rotating shaft 2 is connected to the cutter 3, the guiding portion 24 is fitted in the through hole 34, and 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.
