Technical Field
[0001] This utility model relates to the technical field of food processing equipment, and in particular to a food processing equipment with a structure for quick-change blades. Background Technology
[0002] Currently, with increasing emphasis on health, many families are choosing to make their own soy milk for hygiene and cleanliness, thus driving the market for fully automatic home soy milk makers. Existing technology disclosure number CN205031040U discloses a soy milk maker including a container and a machine head disposed within the container. The machine head contains a motor with paddles connected to it via a shaft. A heating element and a temperature measuring rod are also located on the machine head, connected to a control circuit. A handle is located above the machine head. A handle is attached to the container, with a non-slip rubber sleeve. A non-slip mat is placed at the bottom of the container. However, known food processing appliances such as soy milk makers, blenders, and food processors are difficult to clean after processing. Over time, food residue accumulates on these hard-to-clean parts, making them prone to mold and bacteria, affecting the taste of food, and long-term use is detrimental to health. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a structure for quick replacement of blades in food processing equipment, which enables rapid disassembly and assembly of blades, effective cleaning of blade dead corners, and elimination of food residue.
[0004] This utility model discloses a food processing appliance with a quick-change blade head structure, comprising a body, a blade assembly, and a positioning assembly. The bottom of the blade connector is screwed into the body, and the blade assembly is mounted on the blade connector head via the positioning assembly. The head of the blade connector head has a tapered structure, and the bottom of the blade connector head is connected to the motor shaft via a threaded structure. The positioning assembly and the blade assembly enable quick disassembly and assembly of the blade head. After food processing, the blade head can be removed to effectively clean the dead corners of the blade head and eliminate food residue.
[0005] Preferably, the cutter assembly includes a cutter holder, a blade, and a lifting ring. The blade is located at the top of the cutter holder, and the lifting ring is installed at the middle of the top of the blade. A positioning hole is provided at the bottom of the cutter holder, and the positioning hole is a tapered hole. When removing the cutter head, hold the lifting ring by hand and pull it gently to detach the cutter holder from the cutter connector. When the blade is removed, the dead corners of the cutter head can be thoroughly cleaned. The tapered structure at the head of the cutter connector is aligned with the angle of the positioning hole, allowing for zero-fitting after installation to achieve positioning. This facilitates installation while accurately positioning coaxiality, greatly reducing noise when the cutter head rotates at high speed with the cutter connector shaft.
[0006] Preferably, the positioning component includes a plum blossom mounting part and a C-shaped retaining spring. The plum blossom mounting part is installed on the upper side wall of the cutter connector. An installation groove is opened inside the positioning hole of the cutter holder. The C-shaped retaining spring is located in the installation groove. A retaining spring groove is opened on the top of the cutter connector. The bottom of the positioning hole is set as a plum blossom mounting groove that matches the plum blossom mounting part. When the cutter holder is installed, the C-shaped retaining spring is locked in the retaining spring groove of the cutter connector to maintain a tight fit between the cone part of the cutter connector and the positioning hole. At the same time, the plum blossom mounting part enters the plum blossom mounting groove to achieve synchronous rotation and ensure transmission effect.
[0007] Preferably, the C-shaped retaining spring is made of round steel wire, and the ratio of the opening distance of the C-shaped retaining spring to the circumference of the retaining spring is 1:20-1:3. When installing the tool holder, align the positioning hole with the tool connector head and install downwards. The plum blossom mounting groove is fitted onto the plum blossom mounting part. At this time, when the tool connector head rotates, it will drive the tool head seat to rotate. Continue to press the tool holder downwards, and the C-shaped retaining spring will contact the cone part of the tool connector head, making the diameter of the C-shaped retaining spring larger. When the force reaches a certain level, the C-shaped retaining spring will pass through the maximum diameter of the cone of the tool connector head and be locked into the retaining spring groove. At this time, the inward contraction force of the C-shaped retaining spring will be transformed into the upward pushing force of the tool connector head. This state will keep the tool holder and the cone part of the tool connector head tightly fitted.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning component and the blade component can quickly assemble and disassemble the blade head. After processing the food, the blade head can be removed to effectively clean the dead corners of the blade head and eliminate food residue. Attached Figure Description

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0017] like Figures 1 to 6 As shown, the bottom of the cutter connector 5 is screwed into the inside of the machine body 1. The bottom of the cutter connector 5 is connected to the motor shaft through a threaded structure. The blade 3 is located on the top of the cutter holder 2. The lifting ring 4 is installed at the middle of the top of the blade 3. The bottom of the cutter holder 2 is provided with a positioning hole 9, which is a conical hole. A plum blossom mounting part 6 is installed on the upper side wall of the cutter connector 5. An installation groove is provided inside the positioning hole 9 of the cutter holder 2. A C-shaped retaining spring 7 is located in the installation groove. A retaining spring groove is provided on the top of the cutter connector 5. The bottom of the positioning hole 9 is set as a plum blossom mounting groove 8 that matches the plum blossom mounting part 6. The C-shaped retaining spring 7 is made of round steel wire. The ratio of the opening distance of the C-shaped retaining spring to the circumference of the retaining spring is 1:20-1:3.
[0018] When installing the tool holder 2, align the positioning hole 9 with the tool connector 5 and install it downwards. The plum blossom mounting groove 8 fits onto the plum blossom mounting part 6. At this time, when the tool connector 5 rotates, it will drive the tool holder to rotate. Continue to press the tool holder 2 downwards, and the C-shaped retaining spring 7 will contact the conical part of the tool connector 5, making the diameter of the C-shaped retaining spring 7 larger. When the force reaches a certain level, the C-shaped retaining spring 7 will pass through the maximum diameter of the cone of the tool connector 5 and be locked into the retaining spring groove. At this time, the inward contraction force of the C-shaped retaining spring 7 will be transformed into an upward pushing force on the tool connector 5. This state will keep the tool holder 2 and the conical part of the tool connector 5 tightly fitted, and the C-shaped retaining spring 7 will hold the tool. At the snap ring groove of connector 5, the conical part of connector 5 and the positioning hole 9 are kept in close contact. At the same time, the plum blossom mounting part 6 enters the plum blossom mounting groove 8 to achieve synchronous rotation and ensure transmission effect. When removing the cutter head, hold the lifting ring 4 by hand and pull the lifting ring 4 gently to make the cutter seat 2 disengage from connector 5. When the blade 3 is removed, the dead corner of the cutter head can be thoroughly cleaned. The conical structure of the head of connector 5 is consistent with the angle of the positioning hole 9. After installation, it can be zero-fitted to achieve positioning. While facilitating installation, it can also accurately position coaxiality and greatly reduce the noise of the cutter head when rotating at high speed with the cutter connecting shaft.
[0019] like Figures 1 to 6As shown, this utility model discloses a food processing appliance with a quick-change blade head structure. During operation, when installing the blade head, the positioning hole 9 is aligned with the blade connector 5, and the blade head is installed downwards. The plum blossom mounting groove 8 is fitted onto the plum blossom mounting part 6. When the blade connector 5 rotates, it drives the blade head seat to rotate. Continuing to press down on the blade seat 2, the C-shaped retaining spring 7 contacts the conical part of the blade connector 5, increasing the diameter of the C-shaped retaining spring 7. When the force reaches a certain level, the C-shaped retaining spring 7 passes through the maximum diameter of the cone of the blade connector 5 and is engaged in the retaining spring groove. At this time, the inward contraction force of the C-shaped retaining spring 7 is transformed into an upward pushing force on the blade connector 5. This state maintains a tight fit between the blade seat 2 and the conical part of the blade connector 5. When removing the blade head, hold the lifting ring 4 by hand and gently pull the lifting ring 4 to disengage the blade seat 2 from the blade connector 5. When removing the blade 3, the hard-to-reach areas of the blade head can be thoroughly cleaned.
[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
