Description

Technical Field

[0001] The present application belongs to the field of fluid control technology, and in particular relates to a quick-disassembly structure of a stirrer for a cooking machine and the stirrer. Background Art

[0002] The core function of a household cooking machine is to cook. The stirrer plays a key role in making the food delicious and beautiful. Most stirrers on the market use fixed-axis double-blade, planetary multi-blade, and drum fixed-axis single-blade technologies. The fixed-axis double-blade technology is relatively simple and low-cost, but the stir-frying effect is very poor, the food mixing uniformity is poor, and the phenomenon of agglomeration of ingredients with high viscosity is serious, and the bottom of the pot is easy to burn if it is not scraped; the planetary multi-blade technology is relatively complex. With the introduction of multiple gears, the accumulated gaps between the parts lead to a large deviation between the stirrer and the bottom of the pot, resulting in uneven scraping of the bottom of the pot and the risk of local burning. At the same time, it is inconvenient to clean due to the large number of parts, and the actual use experience is poor; the drum fixed-axis single-blade technology is the most complex, with two parts moving, and the overall cost is very high. Because the pot body has a rotating motion, the top of the pot cannot be effectively sealed, and there is a lot of oil smoke during cooking, and the cooking experience is poor.

[0003] In response to the above problems, the patent number "2023108621678" of "A stirrer for a cooking machine" includes: a stirring shaft, including a main rod and a first connecting portion fixedly connected to the main rod; and a stirring head connected to the first connecting portion, the bottom of the stirring head is lower than the bottom of the main rod, and is used to push the food to move. The stirrer of this invention has a simple structure and can continuously push the food to move, ensuring that the food does not gather at the bottom of the pot for a long time, and preventing the food from burning;

[0004] Since the blender needs to be disassembled for cleaning after each cooking, and the blender is inconvenient to disassemble, users will have a bad experience because of wasting time on installation; and when it is installed again after disassembly and cleaning, it is easy to cause the axial inconsistency between the main shaft of the blender and the main shaft of the power source, causing the blender to shake during operation and unable to complete the cooking action well. Therefore, the connection structure between the blender and the power source becomes particularly important. There is an urgent need for a connection structure of the blender that can keep the main shaft of the blender axially consistent with the main shaft of the power source to ensure that the blender can operate stably, and is easy to disassemble to save users' disassembly time.

[0029] The existing stirrers for cooking need to be disassembled and cleaned after each cooking. The stirrer is inconvenient to disassemble and assemble, resulting in a poor user experience due to wasted time on installation and disassembly. When the stirrer is disassembled and cleaned and then installed again, it is easy to cause the axial inconsistency between the main shaft of the stirrer and the main shaft of the power source, causing the stirrer to shake during operation and failing to complete the cooking action. Therefore, the connection structure between the stirrer and the power source becomes particularly important. There is an urgent need for a connection structure for the stirrer, which can not only keep the main shaft of the stirrer axially consistent with the main shaft of the power source to ensure that the stirrer can operate stably, but also be easy to disassemble and save the user's disassembly time.

The slender guide shaft hole can achieve excellent rotation accuracy, so that the stir-frying machine can run more smoothly and quietly. At the same time, it has a simple and reliable structure, is easy to clean, and has low cost, so that the stirrer can achieve high-efficiency stir-frying comparable to planetary multi-blade and roller fixed-axis single-blade stirrers.
