Description

Technical Field

[0001] The present invention relates to the technical field of the speed reduction mechanism of a chef machine, and particularly to a compact speed reduction mechanism of a chef machine. Background Art

[0002] Existing chef machines generally integrate multiple functions such as dough kneading, stirring, whipping, and chopping. Their core performance largely depends on the power transmission system, especially the speed reduction mechanism. This mechanism is responsible for reducing the rotational speed output by a high-speed motor while significantly increasing the torque output to meet the requirements of high-load operations such as kneading dough and stirring heavy ingredients.

[0003] Existing speed reduction mechanisms of chef machines generally adopt planetary gear speed reduction mechanisms and worm and worm gear speed reduction mechanisms. Generally, in the form of a combination of the two speed reduction mechanisms, to ensure the stable operation and working effect of the multi-energy of the chef machine. However, while the existing multi-functional chef machines use dual speed reduction mechanisms to achieve the purpose of multi-function, their volume is relatively large; However, consumers are becoming increasingly sensitive to the space occupied by kitchen appliances and expect chef machines to be more compact and lightweight. However, speed reduction mechanisms that provide sufficient kneading torque (usually requiring >5 Nm or even higher) are often bulky and heavy, which is in direct contradiction with the market demand for compactness. It is difficult for the existing technology to achieve an extremely compact design while maintaining high performance. Summary of the Invention

[0004] The purpose of the present invention is to provide a compact speed reduction mechanism of a chef machine to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A compact speed reduction mechanism of a chef machine, including a machine shell, a motor is fixedly installed on the outer side of the machine shell, a transmission component one is fixedly connected to the output end of the motor and inside the machine shell, the other end of the transmission component one is fixedly connected to a speed reduction mechanism one, a speed reduction mechanism two is arranged inside the speed reduction mechanism one, a stirring component is fixedly connected to the lower side of the speed reduction mechanism two, a transmission component two is fixedly connected to the end of the speed reduction mechanism one far away from the transmission component one, a crushing component is arranged on the upper side of the transmission component two, electromagnetic clutches are fixedly connected between the transmission component two and the crushing component, and between the speed reduction mechanism one and the speed reduction mechanism two; The transmission component one includes a transmission rod one, a bevel gear one, and a bevel gear two. The output end of the motor is fixedly connected to the transmission rod one, the end of the transmission rod one far away from the motor is fixedly connected to the bevel gear one, and the bevel gear two is meshed with the outer side of the bevel gear one; The speed reduction mechanism one includes a worm and a turbine ring. One end of the bevel gear two is fixedly connected to the worm, the worm is meshed with the turbine ring, and the transmission rod one and the worm rotate inside the machine shell; Start the motor, which drives the first drive rod to rotate. While the first drive rod is rotating, it drives the first bevel gear to rotate. The first bevel gear meshes with and drives the second bevel gear to rotate, and the second bevel gear drives the worm fixedly connected thereto to rotate synchronously. While the worm is rotating, it drives the third bevel gear fixedly connected thereto to rotate. At the same time, the worm meshes with and drives the turbine ring to rotate. The turbine ring is arranged between the first drive rod and the worm, and the included angle formed between the first drive rod and the worm is an acute angle.

[0006] Further, the second reduction mechanism includes a bearing, a rotating plate, a connecting ring, a fixed gear ring, an outer ring gear, a central gear, and a central shaft. The inner side of the machine shell is fixedly connected with a connecting ring, the upper side of the connecting ring is fixedly connected with a fixed gear ring, and the inner side of the fixed gear ring meshes with three groups of evenly distributed outer ring gears. The inner side of the outer ring gear meshes with a central gear. The upper side of the central gear is fixedly connected with a central shaft. One end of the outer ring gear away from the central shaft is fixedly connected with a short shaft, the outer side of the short shaft is sleeved with a bearing, and the outer side of the bearing is provided with a rotating plate.

[0007] The worm meshes with and drives the turbine ring to rotate, realizing the first-stage reduction. When the stirring function needs to be started, an electric current is passed through the coil at the turbine ring. After the coil is energized, a magnetic field is generated, which magnetizes the rotating sleeve, causing the rotating sleeve to generate a magnetic force to attract the pressure plate, thereby overcoming the elastic force of the leaf spring and firmly adsorbing the pressure plate. The turbine ring drives the rotating sleeve to rotate through the annular plate. The rotating sleeve drives the pressure plate and the fixed disk adsorbed thereto to rotate. The fixed disk drives the central shaft to rotate. The central shaft drives the central gear fixedly connected thereto to rotate. The central gear meshes with and drives the three outer ring gears on the outside to rotate meshingly around the inner side of the fixed gear ring, thereby realizing the second-stage reduction. Further, the stirring assembly includes a stirrer, a mounting post, a rotating disk, a connecting crank, and a limiting ring.

[0008] The outer ring gear drives the rotating plate to rotate through the short shaft and the bearing. The rotating plate drives the connecting crank fixedly connected to the center to rotate. The connecting crank drives the rotating disk to rotate. The rotating disk drives the stirrer to rotate eccentrically through the mounting post, thereby realizing the stirring function.

[0009] By designing an acute-angle drive between the first transmission rod and the worm, arranging the turbine ring between the first transmission rod and the worm, and designing the second-stage deceleration mechanism inside the turbine ring, the purpose of compactification is achieved.

[0010] Furthermore, the second transmission component includes a bevel gear three and a bevel gear four. One end of the worm away from the bevel gear two is fixedly connected with the bevel gear three, and the outside of the bevel gear three is engaged with the bevel gear four.

[0011] Furthermore, the crushing component includes a fixed plate, an annular shell, a docking annular ring, a hemispherical shell, a rotating rod, a connecting shaft, and a crushing blade.

[0012] The bevel gear three meshes to drive the bevel gear four to rotate. The bevel gear four drives the movable shaft fixedly connected thereto to rotate. When the crushing function is required, current is passed through the coil at the crushing component. After the coil is energized, a magnetic field is generated, which magnetizes the rotating sleeve, causing the rotating sleeve to generate a magnetic force to attract the pressure plate, thereby overcoming the elastic force of the leaf spring and firmly adsorbing the pressure plate. Since the movable shaft is fixedly connected to the rotating sleeve, the rotating sleeve is driven to rotate synchronously. The rotating sleeve drives the pressure plate and the fixed disk adsorbed thereto to rotate. The fixed disk drives the rotating rod and the connecting shaft to rotate. The connecting shaft drives the crushing blade to rotate, realizing the crushing function. Furthermore, the electromagnetic clutch includes a mounting plate, a coil, a rotating sleeve, a leaf spring, a pressure plate, and a fixed disk. A coil is fixedly connected to one side of the mounting plate. The outside of the coil is rotatably connected with a rotating sleeve. A pressure plate is arranged on the side of the rotating sleeve away from the mounting plate. A fixed disk is arranged on the side of the pressure plate away from the rotating sleeve. The pressure plate and the fixed disk are connected by multiple groups of leaf springs.

[0013] Furthermore, the rotating rod is fixedly connected to the corresponding fixed disk. A movable shaft is fixedly connected to the upper side of the bevel gear four. The inner side of the movable shaft is fixedly connected to the corresponding rotating sleeve.

[0014] Furthermore, the central shaft is fixedly connected to the corresponding fixed disk. An annular plate is fixedly connected to the inner side of the turbine ring. The annular plate is fixedly connected to the corresponding rotating sleeve.

[0015] Furthermore, the included angle formed between the first transmission rod and the worm is 40 degrees. An annular groove corresponding to the turbine ring is arranged inside the machine shell.

[0016] Compared with the prior art, the present invention provides a compact speed reduction mechanism for a chef machine, which has the following beneficial effects: 1. For this compact speed reduction mechanism of the chef machine, by designing an acute-angle drive between the first drive rod and the worm, arranging the turbine ring between the first drive rod and the worm, and designing the second speed reduction mechanism inside the turbine ring, the purpose of compactness is achieved, greatly compressing the required space of the chef machine. At the same time, the two speed reduction mechanisms are well integrated into one, making the space occupied by the two speed reduction mechanisms the same as that occupied by one existing speed reduction mechanism. Moreover, the stirring component and the crushing component are designed at the upper and lower positions on the same side, greatly compressing the longitudinal space of the chef machine, reducing the space, making the transmission more compact, reducing the transmission consumption over a long distance, meeting the needs of existing consumers, and at the same time ensuring the integrity of the functions.

[0017] 2. For this compact speed reduction mechanism of the chef machine, by arranging an integrated electromagnetic clutch at both the stirring assembly and the crushing assembly, the function of starting the crushing or stirring can be realized by controlling the engagement and disengagement of the electromagnetic clutch. At the same time, the electromagnetic clutch is well placed inside the stirring assembly and the crushing assembly without increasing the practical space. BRIEF DESCRIPTION OF THE DRAWINGS
