Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and specifically to a transmission mechanism for a food processor. Background Technology
[0002] A food processor is a multi-functional household food processing device. Currently, food processors on the market generally have functions such as kneading dough, mixing, whipping egg whites, and mincing meat; due to their rich functionality, they can help users make a variety of foods, and are therefore very popular.
[0003] Utility model patent CN221533547U discloses a transmission mechanism for a food processor, including a headstock; a planetary gear system including an internal gear ring, planetary gears, a planetary carrier, and a sun shaft, with the planetary gears meshing with the internal gear ring and the lower end of the sun shaft fixedly connected to the planetary gears; an output shaft, with its upper end fixed to the planetary gears and its output end rotatably passing through the planetary carrier; and a drive assembly, housed within the headstock, including a motor, a worm gear located at the motor's output end, and a worm wheel for driving the sun shaft to rotate, with the worm gear and worm wheel meshing for transmission. This prior art uses a worm gear and worm wheel to drive the sun shaft, offering advantages such as low noise, a large transmission ratio, and smooth transmission, thus effectively solving the problem of high noise levels in traditional food processors. However, this prior art still has structural shortcomings. Because the drive assembly generates high heat during operation, and this prior art lacks a heat dissipation device, the drive assembly cannot dissipate heat, resulting in a short service life, and the heat can also be transferred to the headstock, posing a risk of burns.
[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content
[0005] To address the problems of existing technologies, this invention provides a transmission mechanism for a food processor that effectively solves the heat dissipation problem of the drive components.
[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:
[0007] A transmission mechanism for a food processor includes a drive unit, a conical solar planetary gear set, and a mixing element. The output end of the drive unit is connected to the input end of the conical solar planetary gear set, and the output end of the conical solar planetary gear set is connected to the mixing element. With this configuration, the drive unit acts as a power source, and after speed adjustment via the conical solar planetary gear set, it transmits power to the mixing element, thereby driving the mixing element to rotate and achieve mixing.
[0008] According to the above scheme, the driving device includes a housing and a motor assembly. The housing has an air inlet and an air outlet, and a heat dissipation duct is formed inside the housing, connecting the air inlet and the air outlet. The motor assembly is located inside the heat dissipation duct, and a rotatable fan assembly is installed inside the heat dissipation duct. This arrangement, by placing the motor assembly inside the heat dissipation duct and installing the rotatable fan assembly within it, allows the fan assembly to quickly dissipate the heat generated by the motor assembly during operation, thereby extending the service life of the motor assembly.
[0009] According to the above scheme, the fan assembly is driven to rotate by a motor assembly; the fan assembly includes an exhaust fan blade and a centrifugal fan blade, with the exhaust fan blade located inside the air inlet and the centrifugal fan blade located inside the air outlet, and the motor assembly located between the exhaust fan blade and the centrifugal fan blade. This configuration allows the motor assembly to drive the agitator while simultaneously driving the exhaust fan blade and the centrifugal fan blade to rotate, achieving multiple functions in one machine; when the exhaust fan blade rotates, it can quickly draw in cold air near the air inlet, rapidly exchange heat with the cold air generated during motor operation, and then quickly discharge it through the air outlet under the action of the centrifugal fan blade.
[0010] According to the above scheme, the motor assembly includes a motor, a worm gear, and two worm wheels. The worm gear passes through both ends of the motor and extends outwards. The exhaust fan is fixed to the first end of the worm gear, and the centrifugal fan is fixed to the second end of the worm gear. The two worm wheels are symmetrically arranged on both sides of the worm gear between the exhaust fan and the motor, and the two worm wheels are meshed with the worm gear. At least one worm wheel is equipped with a primary output shaft, which is connected to a conical solar planetary gear set, which is connected to the agitator. With this configuration, when the motor is working, it drives the worm gear to rotate the exhaust fan and the centrifugal fan; at the same time, it drives the two worm wheels to rotate synchronously. The primary output shaft on the worm wheel drives the conical solar planetary gear set to rotate, which in turn drives the agitator to rotate, thereby achieving agitation.
[0011] According to the above scheme, the conical sun planetary gear set includes a conical sun gear, a conical gear ring, a planetary gear support, and a gearbox cover. The gearbox cover and the conical gear ring are fixedly connected and form a receiving cavity. The conical sun gear and the planetary gear support are located in the receiving cavity. The planetary gear support is provided with rotatable conical planetary gears with shafts and conical planetary gears without shafts. The conical planetary gears with shafts are connected to the stirring component. The conical sun gear is movably mounted on the planetary gear support. A secondary input shaft is formed at the upper end of the conical sun gear. The secondary input shaft passes through the gearbox cover and is engaged with the primary output shaft. A conical sun tooth is formed at the lower end of the conical sun gear. The conical sun tooth meshes with the conical planetary gears with shafts and the conical planetary gears without shafts. An internal gear ring is formed on the inner wall of the conical gear ring. The conical planetary gears with shafts and the conical planetary gears without shafts mesh with the internal gear ring. With this configuration, when the conical sun gear meshes and rotates with the axial conical planetary gear and the non-axial conical planetary gear, the axial conical planetary gear and the non-axial conical planetary gear rotate. Specifically, there is one axial conical planetary gear and several non-axial conical planetary gears (preferably two or three, mounted on the planetary gear carrier). The secondary input shaft is connected to the primary output shaft. The conical sun gear is mounted on the planetary gear carrier, and the conical sun gear meshes with the axial conical planetary gear and the several non-axial conical planetary gears. At the same time, the axial conical planetary gear and the several non-axial conical planetary gears mesh with the bevel gear ring. When the axial conical planetary gear and the several non-axial conical planetary gears rotate in mesh with the bevel gear ring, the planetary gear carrier revolves. Therefore, the mixing component follows the rotation of the axial conical planetary gear and the revolution of the planetary gear carrier.
[0012] According to the above scheme, the planetary gear support is provided with mounting holes, and a wear-resistant sleeve is fixed in the mounting holes. The bevel planetary gear with shaft is provided with an outer cylindrical shaft, which is rotatably mounted in the wear-resistant sleeve and connected to the agitator. This arrangement, by providing a wear-resistant sleeve in the mounting holes, can effectively protect the mounting holes and prevent friction damage when the bevel planetary gear with shaft drives the rotating agitator, thereby ensuring the normal operation of the bevel planetary gear relative to the planetary gear support.
[0013] According to the above scheme, the outer cylindrical shaft has a socket hole formed inside, and the stirring component includes a stirring rod and a cover. The upper end of the stirring rod has a connector formed therein, and the connector is inserted into the socket hole. This arrangement allows the stirring component and the bevel planetary gear with shaft to be connected, so that the stirring component rotates with the bevel planetary gear. Preferably, the socket hole is an internal hexagonal socket, and the connector is preferably an external hexagonal plug. The cover is used to limit the movement of the bevel gear ring, preventing liquid from entering the bevel gear ring during stirring.
[0014] According to the above scheme, the primary output shaft, secondary input shaft, conical sun gear, planetary gear support, and bevel gear ring are coaxially arranged. This arrangement ensures the concentricity of the worm gear when it is subjected to force during rotation; moreover, the primary output shaft, secondary input shaft, conical sun gear, planetary gear support, and bevel gear ring are sequentially meshed, making the entire structure compact and space-saving.
[0015] According to the above scheme, the motor is equipped with a mounting bracket, and the worm gear is rotatably mounted on the mounting bracket. The first-stage output shaft extends downward along the central axis of the worm gear. This arrangement positions the two worm gears at their upper limits on the mounting bracket, and the two worm gears are symmetrically arranged on both sides of the worm. The two worm gears mesh with the worm, making the assembly more stable and preventing the risk of tooth slippage between the worm gears and the worm. Furthermore, the two worm gears clamp the worm in the middle for meshing and linkage, ensuring the concentricity of the force on the motor and worm.
[0016] According to the above scheme, the worm gear is equipped with a medium-speed output shaft, which extends upward along the central axis of the worm gear. This configuration allows for connection to other medium-speed mixing equipment according to user requirements, making it more convenient to use.
[0017] According to the above scheme, a high-speed output connector is fixed on the worm gear. This configuration allows for connection to other high-speed mixing equipment according to user requirements, making it more convenient to use.
[0018] The present invention provides a food processor, which includes the aforementioned food processor transmission mechanism.
[0019] The beneficial effects of this utility model are:
[0020] This invention is designed such that the motor assembly is placed inside the heat dissipation duct, and a rotatable fan assembly is provided inside the heat dissipation duct. When the fan assembly rotates, it can quickly dissipate the heat generated by the motor assembly during operation, thereby improving the service life of the motor assembly.

Detailed Implementation
[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0029] like Figures 1 to 5 As shown, the transmission mechanism of the food processor of this utility model includes a drive device 100, a conical solar planetary gear set 200, and a mixing element 300. The output end of the drive device 100 is connected to the input end of the conical solar planetary gear set 200, and the output end of the conical solar planetary gear set 200 is connected to the mixing element 300. With this configuration, the drive device 100 serves as a power source, and after speed adjustment by the conical solar planetary gear set 200, it transmits power to the mixing element 300, thereby driving the mixing element 300 to rotate and achieve mixing.
[0030] Furthermore, the drive device 100 includes a housing 170 and a motor assembly. The housing 170 is provided with an air inlet 171 and an air outlet 172, and a heat dissipation duct is formed inside the housing 170, connecting the air inlet 171 and the air outlet 172. The motor assembly is disposed within the heat dissipation duct, and a rotatable fan assembly is provided within the heat dissipation duct. This arrangement, with the motor assembly disposed within the heat dissipation duct and the rotatable fan assembly within the heat dissipation duct, allows the heat generated by the motor assembly during operation to be quickly dissipated when the fan assembly rotates, thereby improving the service life of the motor assembly.
[0031] Furthermore, the fan assembly is driven to rotate by a motor assembly; the fan assembly includes an exhaust fan 150 and a centrifugal fan 160, with the exhaust fan 150 located inside the air inlet 171 and the centrifugal fan 160 located inside the air outlet 172, and the motor assembly located between the exhaust fan 150 and the centrifugal fan 160. This configuration allows the motor assembly to simultaneously drive the agitator 300 to stir and drive the exhaust fan 150 and the centrifugal fan 160 to rotate, achieving multiple functions in one unit. When the exhaust fan 150 rotates, it can quickly draw in cold air near the air inlet 171. After rapid heat exchange with the cold air generated by the motor 110 during operation, the air is quickly discharged through the air outlet 172 under the action of the centrifugal fan 160.
[0032] Furthermore, the motor assembly includes a motor 110, a worm gear 120, and two worm wheels 130. The worm gear 120 passes through both ends of the motor 110 and extends therefrom. An exhaust fan 150 is fixed to the first end of the worm gear 120, and a centrifugal fan 160 is fixed to the second end of the worm gear 120. The two worm wheels 130 are symmetrically arranged on both sides of the worm gear 120 between the exhaust fan 150 and the motor 110. The two worm wheels 130 are meshed with the worm gear 120. At least one worm wheel 130 is provided with a primary output shaft 131, which is connected to a conical solar planetary gear set 200. The conical solar planetary gear set 200 is connected to the stirring component 300. With this configuration, when the motor 110 is working, it drives the worm gear 120 to rotate the exhaust fan blade 150 and the centrifugal fan blade 160; at the same time, it drives the two worm wheels 130 to rotate synchronously, and the first-stage output shaft 131 on the worm wheel 130 drives the conical solar planetary gear set 200 to rotate, and the conical solar planetary gear set 200 then drives the stirring component 300 to rotate, thereby achieving stirring.
[0033] The worm gear 120 is horizontally mounted and drives two worm wheels 130 to rotate synchronously when it rotates. This design has high concentricity, small size, large speed ratio, and can achieve 90-degree change of direction at the same time. Specifically, the worm gear 120 is horizontally mounted and the conical solar planetary gear set 200 is vertically mounted relative to the worm gear 120. The stirring component 300 is mounted at an angle β with the conical solar planetary gear set 200. Preferably, 20°≤β≤40°.
[0034] Furthermore, the conical sun planetary gear set 200 includes a conical sun gear 230, a conical gear ring 240, a planetary gear carrier 250, and a gearbox cover 260. The gearbox cover 260 and the conical gear ring 240 are fixedly connected and form a receiving cavity. The conical sun gear 230 and the planetary gear carrier 250 are disposed within the receiving cavity. The planetary gear carrier 250 is provided with a rotatable conical planetary gear 210 with a shaft and a conical planetary gear 220 without a shaft. The conical planetary gear 210 with a shaft is connected to the stirring member 300. The conical sun gear 230 is movably mounted... Mounted on the planetary gear carrier 250, the upper end of the conical sun gear 230 is formed with a secondary input shaft 231, which passes through the gearbox cover 260 and is engaged with the primary output shaft 131; the lower end of the conical sun gear 230 is formed with a conical sun tooth 232, which meshes with the axial conical planetary gear 210 and the axial non-axial conical planetary gear 220; the inner wall of the conical gear ring 240 is formed with an internal gear ring 241, which meshes with the axial conical planetary gear 210 and the axial non-axial conical planetary gear 220. With this configuration, when the conical sun gear 230 meshes and rotates with the shafted conical planetary gear 210 and the shaftless conical planetary gear 220, the shafted conical planetary gear 210 and the shaftless conical planetary gear 220 rotate on their own axes. Specifically, there is one shafted conical planetary gear 210 and several shaftless conical planetary gears 220 (preferably two or three, mounted on the planetary gear carrier 250). The secondary input shaft 231 is connected to the primary output shaft 131, and the conical sun gear 230 is mounted on the planetary gear carrier. On 250, the conical sun gear 232 meshes with the axial conical planetary gear 210 and several axialless conical planetary gears 220; at the same time, the axial conical planetary gear 210 and several axialless conical planetary gears 220 mesh with the bevel gear ring 240. When the axial conical planetary gear 210 and several axialless conical planetary gears 220 rotate in mesh with the bevel gear ring 240, the planetary gear support 250 revolves; therefore, the stirring component 300 follows the rotation of the axial conical planetary gear 210 and the revolution of the planetary gear support 250.
[0035] Furthermore, the planetary gear support 250 is provided with a mounting hole 251, and a wear-resistant sleeve 252 is fixed inside the mounting hole 251. The bevel planetary gear 210 with a shaft is provided with an outer cylindrical shaft 211, which is rotatably mounted inside the wear-resistant sleeve 252. The outer cylindrical shaft 211 is connected to the stirring component 300. This arrangement, by providing the wear-resistant sleeve 252 inside the mounting hole 251, can effectively protect the mounting hole 251, preventing friction damage when the bevel planetary gear 210 drives the rotating stirring component 300, thereby ensuring the normal operation of the bevel planetary gear 210 relative to the planetary gear support 250.
[0036] The difference between the bevel planetary gear 210 with shaft and the bevel planetary gear 220 without shaft is that the bevel planetary gear 210 with shaft is provided with an outer cylindrical shaft 211.
[0037] Furthermore, the outer cylindrical shaft 211 has a plug hole 212 formed inside, and the stirring component 300 includes a stirring rod 310 and a cover 320. The upper end of the stirring rod 310 has a plug 311 formed therein, and the plug 311 is engaged with the plug hole 212.
[0038] This configuration allows the agitator 300 and the bevel planetary gear 210 to be connected, so that the agitator 300 rotates with the bevel planetary gear 210. The insertion hole 212 is preferably an internal hexagonal socket, and the plug 311 is preferably an external hexagonal plug. The cover 320 is used to limit the movement of the bevel gear ring 240 and prevent liquid from entering the bevel gear ring 240 during agitation.
[0039] Furthermore, the primary output shaft 131, secondary input shaft 231, conical sun gear 232, planetary gear support 250, and bevel gear ring 240 are coaxially arranged. This arrangement ensures the concentricity of the worm gear 120 when it is subjected to rotational force. The primary output shaft 131, secondary input shaft 231, conical sun gear 232, planetary gear support 250, and bevel gear ring 240 are sequentially interlocked, making the entire structure compact and space-saving.
[0040] Furthermore, the motor 110 is provided with a mounting bracket 140, and the worm gear 130 is rotatably mounted on the mounting bracket 140. The first-stage output shaft 131 extends downward along the central axis of the worm gear 130. This arrangement positions the two worm gears 130 at the upper limit of the mounting bracket 140, and the two worm gears 130 are symmetrically arranged on both sides of the worm 120. The two worm gears 130 are meshed with the worm 120, making the assembly more stable and preventing the risk of tooth slippage between the worm gears 130 and the worm 120. In addition, the two worm gears 130 clamp the worm 120 in the middle for meshing and linkage, ensuring the concentricity of the force on the motor worm 120.
[0041] Specifically, the first-stage output shaft 131 extends downward through the housing 170.
[0042] Among them, at least one of the two worm gears 130 is provided with a first-stage output shaft 131 for connecting and rotating with the conical sun planetary gear set 200, while the other worm gear 130 is not connected to other parts for rotation and plays an auxiliary role.
[0043] Furthermore, the worm gear 130 is equipped with a medium-speed output shaft 132, which extends upward along the central axis of the worm gear 130. This configuration allows for the connection of other medium-speed mixing equipment according to user requirements, making it more convenient to use.
[0044] Specifically, the medium-speed output shaft 132 extends upward through the housing 170.
[0045] Furthermore, a high-speed output connector 180 is fixed on the worm gear 120. This configuration allows for connection to other high-speed mixing equipment according to user requirements, making it more convenient to use.
[0046] Specifically, the worm gear 120 extends backward through the housing 170 and is then fixedly connected to the high-speed output connector 180.
[0047] Among them, the high-speed output connector 180 is directly driven to rotate by the worm gear 120, which is a high-speed output; the medium-speed output shaft 132 is driven by the meshing of the worm gear 120 and the worm wheel 130, which is a medium-speed output; the first-stage output shaft 131 drives the agitator 300 to rotate after being reduced by the conical solar planetary gear set 200, which is a low-speed output.
