Description

Technical Field

[0001] This utility model relates to the technical field of food processing machines, and in particular to a food processing machine that is safe to operate. Background Technology

[0002] With social development and improved living standards, people are increasingly pursuing more diverse and healthier diets. As a result, various food processing machines have gradually become smaller and entered thousands of households, such as juicers, blenders, and multi-functional food processors. These machines not only meet people's needs for healthy and nutritious diets but also greatly improve their quality of life, thus gaining popularity.

[0003] Existing multi-functional food processors have added shredding and slicing functions. The shredding and slicing assembly is attached to the main unit and is a detachable structure. The assembly includes the main body, a blade, and a rotating disc. The blade is installed in the rotating disc, which is then installed into the main body to form the shredding and slicing assembly. The assembly is then attached to the main unit, and the rotating disc is connected to a motor in the main unit. During operation, the motor drives the rotating disc in the assembly to rotate, and food enters from the feeding port of the main body. The blade in the rotating disc rotates and cuts the food in the feeding port, thus achieving the slicing function. By changing different blades, the shredding and slicing functions can be achieved. However, this structure has safety issues. When a blade is missing or insufficiently installed, there will be a large hole in the rotating disc. During operation, fingers can pass through the hole and accidentally injure the fingers when the disc rotates, causing a safety accident and affecting the safety and reliability of the food processor. In addition, when the rotating disc with an adapter and blade is directly installed on the main unit, it can also rotate and operate, but the exposed blade can directly cut people, causing a safety accident and affecting the safety and reliability of the food processor. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing food processing machines in terms of safety issues and provides a food processing machine that improves operational safety and enhances safety performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safe food processing machine, comprising:

[0007] Host;

[0008] The motor is detachably and fixedly connected to the interior of the main unit. A drive shaft is provided on the output end of the motor. One end of the drive shaft is located inside the main unit and fixedly connected to the motor. The other end of the drive shaft passes through the side wall of the main unit and is located outside the main unit. The drive shaft is rotatably connected to the main unit under the drive of the motor.

[0009] A material cylinder, one end of which is rotatably connected to a transmission part and detachably connected to the main unit, one end of which is located outside the material cylinder and is detachably fixedly connected to the end of the transmission shaft located outside the main unit, the other end of which is located inside the material cylinder, a feed port communicating with the inside of the material cylinder is fixed on the top side of the material cylinder, and the other end of the material cylinder is a discharge end;

[0010] The rotary blade assembly has one end detachably and fixedly connected to the end of the transmission unit located inside the material cylinder. Driven by a motor, the rotary blade assembly is rotatably connected inside the material cylinder. The user feeds food into the material cylinder through the inlet. Driven by the motor, the rotary blade assembly rotates at high speed inside the material cylinder via the transmission shaft, slicing or shredding the food. Because the rotary blade assembly is installed inside the material cylinder, it avoids being exposed and could cause injury, thus improving safety and ensuring the safety and reliability of the food processing machine.

[0011] Preferably, the main unit has a C-shaped structure, with a mounting groove at the top opening. The motor is horizontally arranged inside the top of the main unit, and the other end of the drive shaft passes through the bottom of the mounting groove and is located inside the groove. One end of the material cylinder is detachably connected to the mounting groove. A base is fixed to the bottom of the main unit, and a circuit board is detachably connected inside the main unit. An operation switch is provided on the outer wall of the main unit, located at the bottom of the main unit and electrically connected to the motor via the circuit board. The material cylinder and the mounting groove can be fitted together by inserting the end of the material cylinder into the mounting groove and then locking it by rotation. Since this structure is a relatively mature existing technology, it will not be described in detail here. The horizontal arrangement of the motor ensures that the rotating blade assembly connected to the motor via the transmission unit is also horizontally arranged. The user controls the working state of the motor through the operation switch, thereby facilitating the start and stop of the rotating blade assembly.

[0012] Preferably, the rotating blade assembly includes a rotating disk and several cutting blades. The rotating disk is cylindrical, and the cutting blades are evenly distributed along the circumference of the rotating disk on its sidewalls. The cutting blades are fixedly connected to the rotating disk, forming an integral structure. One end of the rotating disk is detachably and fixedly connected to the end of the transmission unit located inside the material cylinder. The other end of the rotating disk is located inside the discharge end of the material cylinder. The feed inlet is located on the side of the rotating disk and corresponds vertically to the cutting blades. The detachable connection between one end of the rotating disk and the transmission unit can be a simple plug-in or snap-fit ​​structure, which is common in existing technology and will not be described in detail here. The fixed connection between the cutting blades and the rotating disk, forming an integral structure, helps prevent missing cutting blades, thus avoiding injury caused by fingers entering through missing holes during operation, further improving safety performance.

[0013] Preferably, the diameter of the rotating disk gradually increases linearly from the end detachably and fixedly connected to the transmission unit to the end located inside the discharge end. This design gives the rotating disk a funnel-shaped structure, which facilitates the discharge of shredded or sliced ​​food from the discharge end.

[0014] Preferably, the discharge end of the material cylinder is provided with an annular end cap, which is fitted onto the outer wall of the rotating disk and detachably fixed to the discharge end. A protruding edge is fixedly fixed to the outer wall of the discharge end of the rotating disk, and a limiting groove matching the protruding edge is formed on the inner wall of the discharge end. The protruding edge is rotatably connected between the limiting groove and the end cap. A discharge hopper extends downwards from the end cap and is located on the bottom side of the material cylinder. The fit between the end cap and the discharge end can be a simple, easily disassembled structure such as a rotary snap-fit, which is relatively simple and common in existing technology, and therefore will not be elaborated upon here. The end cap limits the rotation of the rotating disk, ensuring its stability and safety during rotation. The discharge hopper provides good guidance for collecting food that has fallen after being shredded or sliced.

[0015] Preferably, the transmission unit includes a fixed ring, a drive shaft, and a transmission block. The diameter of one end of the fixed ring is larger than the diameter of the other end, and the cross-sectional shape of the fixed ring is T-shaped. The end of the material cylinder has a mounting hole at its center that matches the smaller diameter end of the fixed ring. The smaller diameter end of the fixed ring passes through the mounting hole and is inserted into one side of the transmission block. The fixed ring is rotatably connected to the mounting hole. One end of the drive shaft is located outside the material cylinder and is detachably fixedly connected to the transmission shaft. The other end of the drive shaft passes through the center of the fixed ring and is located inside the material cylinder and is fixedly connected to the transmission block. The portion of the drive shaft that passes through the fixed ring is detachably connected to the fixed ring. The transmission block is located inside the material cylinder and is detachably fixedly connected to the end of the rotating blade assembly. When installing the transmission unit, first insert the smaller diameter end of the retaining ring into the mounting hole from the outside. Then, insert the drive shaft into the center of the retaining ring, so that one end is outside the material cylinder for easy connection with the drive shaft, and the other end is inside the material cylinder. Finally, fix the transmission block to the end of the drive shaft inside the material cylinder. This allows the transmission unit to connect with the rotating disk through the transmission block, so that the rotating disk can be driven to rotate by the motor. The transmission unit is located inside the material cylinder, which facilitates the power transmission between the main unit and the rotating blade assembly and prevents power loss.

[0016] Preferably, the drive shaft is inserted and fixed inside one end of the drive shaft located outside the material cylinder. The other end of the drive shaft is provided with a threaded groove. One side of the transmission block is provided with a slot that matches the drive shaft. The other side of the transmission block is provided with a bolt hole that communicates with the slot. A bolt is provided in the bolt hole. The drive shaft is fixedly connected to the transmission block by the bolt matching the threaded groove. A cover plate covering the bolt is fixed on the other side of the transmission block, and the cover plate is in contact with the bolt. When installing the transmission unit, first insert the smaller diameter end of the retaining ring into the mounting hole from the outside. Then, insert the drive shaft into the center of the retaining ring, so that one end is outside the material cylinder for easy insertion and fixing with the drive shaft, and the other end is inside the material cylinder. Next, fix the transmission block and the end of the drive shaft inside the material cylinder with bolts. Finally, cover the machine with the cover plate for fixation. The contact between the cover plate and the bolts helps to prevent the bolts from loosening and thus fixes the transmission unit. This avoids the danger of the machine directly connecting to the main unit without passing through the material cylinder during rotation, and improves the stability and safety of the machine during operation. The cover plate and the transmission block can be fixed by applying glue or other methods, but are not limited to these.

[0017] Preferably, the outer wall of the portion of the drive shaft passing through the fixed ring is provided with a limiting step surface one, and the inner end of the fixed ring with a larger diameter is provided with a limiting step surface two that contacts the limiting step surface one. The outer end of the fixed ring with a smaller diameter is fitted with a wear-resistant washer, which is positioned between the end face of the material cylinder and one side of the transmission block. The matching arrangement of the limiting step surface one and the limiting step surface two ensures that after the drive shaft and the transmission block are fixed with bolts, the fixed ring is also fixed simultaneously, resulting in a simple structure that is easy to install and fix.

[0018] The beneficial effects of this utility model are:

[0019] 1. Because the rotary blade assembly is installed inside the material cylinder, it avoids being exposed and causing injury, thereby improving safety performance and ensuring the safety and reliability of the food processing machine;

[0020] 2. The cutter is fixedly connected to the rotating disk and forms an integral structure, which helps to prevent the cutter from being missing. This helps to avoid fingers from being inserted through the missing hole during operation and causing injury, thus further improving safety performance.

[0021] 3. The transmission unit is fixedly installed inside the material cylinder to facilitate power transmission between the main machine and the rotating blade assembly, and to prevent loss. At the same time, it prevents the rotating blade assembly from rotating directly to the main machine without passing through the material cylinder, which could cause danger.
