Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring specifically to fig. 1 and 2, the present utility model discloses a knife assembly, comprising:

a stirring tool apron 1;

A stirring blade assembly 2, the stirring blade assembly 2 comprising a cutter shaft 21 and a blade 22 connected to the cutter shaft 21;

The noise reduction oil seal 3 is provided with a waterproof lip part 31 and an elastic shock absorber 32, the waterproof lip part 31 and the elastic shock absorber 32 are integrally formed, a bearing cavity 33 is formed in the elastic shock absorber 32, and the noise reduction oil seal 3 is fixedly connected to the stirring tool apron 1;

The bearing element 4, the bearing element 4 is embedded in the bearing cavity 33, and the cutter shaft 21 of the stirring cutter assembly 2 sequentially penetrates through the waterproof lip 31 and the bearing element 4 and extends out of the stirring cutter holder 1.

In this embodiment, since the waterproof lip 31 and the elastic shock absorber 32 are integrally formed, the noise reduction oil seal 3 has good waterproof performance as a whole, wherein the waterproof lip 31 includes the through assembly hole 311 communicating with the bearing cavity 33 and the waterproof protrusion 312, and the waterproof protrusion 312 is disposed on the wall of the through assembly hole 311, so when the cutter shaft 21 of the stirring cutter assembly 2 is inserted into and penetrates through the through assembly hole 311 of the waterproof lip 31, the waterproof protrusion 312 will abut against the cutter shaft 21, so that a sealing waterproof effect is formed between the cutter shaft 21 and the waterproof protrusion 312.

It should be noted that, for achieving a better stress effect and waterproof effect, as shown in fig. 4, the waterproof protrusions 312 are preferably configured in a plurality of numbers, and the waterproof protrusions 312 are uniformly distributed along the central axis direction of the through assembly hole 311. In view of the stable stress of the cutter shaft 21, as shown in fig. 1, the bearing elements 4 are preferably arranged in two or more, and the bearing elements 4 may be ball bearings, needle bearings, or the like.

In addition, the noise reduction oil seal 3 is made of elastic materials, such as rubber and silica gel, and when the blade 22 of the stirring blade assembly 2 moves at a high speed or the food is cut at a high speed and generates severe irregular vibration, wherein, part of the vibration generated and transmitted by the cutter shaft 21 is received by the waterproof lip 31 of the noise reduction oil seal 3, that is, the vibration of the cutter shaft 21 is directly transmitted to the waterproof lip 31 of the noise reduction oil seal 3, and the other part of the vibration is received by the elastic shock absorber 32 of the noise reduction oil seal 3, that is, the vibration of the cutter shaft 21 is transmitted to the elastic shock absorber 32 through the bearing element 4. In this way, the vibration received from the waterproof lip part 31 and the elastic shock absorber 32 will be uniformly buffered and digested, and the noise reduction oil seal 3 has better integrity and thus better buffering and shock absorbing effects due to the integral formation of the waterproof lip part 31 and the elastic shock absorber 32.

In the above-mentioned process, only the bearing element 4 is required to be installed in the bearing cavity 33 of the noise reduction oil seal 3, then the noise reduction oil seal 3 is assembled into the stirring blade holder 1, and finally, the plugging assembly of the stirring blade assembly 2 is completed. Therefore, the number of parts and the structure of the parts of the traditional stirring cutter assembly 2 are very effectively simplified, so that the assembly process is simplified, and the production and manufacturing cost, the processing and assembling difficulty and the later maintenance difficulty are reduced.

Since the cutter shaft 21 of the stirring blade assembly 2 itself vibrates during high-speed operation, particularly during high-speed cutting, severe irregular vibration occurs. In this way, the bearing element 4 can irregularly squeeze the elastic shock absorber 32, so that a gap is generated between the waterproof lip part 31 and the cutter shaft 21, or when the bearing element 4 generates larger vibration, the bearing element directly collides and squeezes the waterproof lip part 31, and a gap is generated between the waterproof lip part 31 and the cutter shaft 21, so that the buffering, shock absorbing and sealing effects of the noise reduction oil seal 3 are reduced.

As a further preferable mode of the present embodiment, the knife assembly further includes an inner oil seal gasket 61, where the inner oil seal gasket 61 is preferably a washer/spacer, a side of the bearing cavity 33 near the waterproof lip 31 is provided with a limit step 35, the inner oil seal gasket 61 is fitted in the bearing cavity 33, and the inner oil seal gasket 61 is sandwiched and fixed between the limit step 35 and the bearing element 4, that is, before the bearing element 4 is fitted in the bearing cavity 33 of the noise reduction oil seal 3, the inner oil seal gasket 61 is placed in the bearing cavity 33, the bearing element 4 is placed in the bearing cavity 33 until the bearing element 4 makes contact with a side surface of the inner oil seal gasket 61 near the waterproof lip 31, and finally, the fitting between the noise reduction oil seal 3 and the stirring blade holder 1 is performed, and the stirring knife assembly 2 is inserted.

In this way, the inner oil seal gasket 61 is abutted against and contacted with the outer ring of the bearing element 4, on one hand, through the cooperation of the inner oil seal gasket 61 and the bearing element 4, the assembly among the inner oil seal gasket 61, the bearing element 4 and the noise reduction oil seal element 3 is more compact, and the stability of the stirring blade assembly 2 in the high-speed cutting process is ensured, so that the better buffering, damping and sealing effects of the noise reduction oil seal element 3 are better ensured. On the other hand, the contact surface between the outer ring of the bearing element 4 and the limit step 35 is enlarged by the inner oil seal gasket 61, thereby ensuring the stress stability between the outer ring of the bearing element 4 and the noise reduction oil seal 3.

In addition, as shown in fig. 1, in order to avoid that the cutter shaft 21 of the stirring cutter assembly 2 is in contact with or collides with the stirring blade holder 1 due to vibration during use of the cutter assembly, a safety gap is usually preset between the cutter shaft 21 and the stirring blade holder 1. In order to ensure the sanitation of the knife assembly in the use process, the knife assembly is usually disassembled and cleaned after the knife assembly is used, and in order to avoid the liquid such as cleaning liquid or water from flowing into the bearing cavity 33 from the safety gap and damaging the bearing element 4, the inventor provides a preferred mode, and particularly please refer to fig. 1, 2 and 4, the knife assembly further comprises a lower oil seal element 5, the knife shaft 21 of the stirring knife assembly 2 sequentially penetrates through the waterproof lip 31, the bearing element 4 and the lower oil seal element 5, and the lower oil seal element 5 is fixedly connected with the stirring knife holder 1.
