For example, utility model patent CN212213534U discloses a transmission device for a kitchen center, including a motor head, a motor, and a reducer. The motor has a rotating shaft with an input gear at the lower end. The reducer includes a reduction bracket, which is fixedly connected to the motor head.

The planetary support has planetary gears and a stirring shaft. The upper end of the stirring shaft is fixedly connected to the planetary gears. The planetary gears mesh with the output gear and the planetary disk for transmission.

[0004] The aforementioned transmission structures all suffer from low transmission efficiency, easy tooth slippage, and low operating power.

[0005] Therefore, there is still room for improvement in the existing technology. Utility Model Content

[0006] To address the problems of easy tooth slippage, low transmission efficiency, and low power in existing technologies that use a motor, motor worm gear, and worm wheel for transmission, this utility model provides a kitchen center.

[0007] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0008] A kitchen center includes a main body with a rotating arm. A power transmission mechanism is housed within the rotating arm. The power transmission mechanism includes a motor assembly, a solar planetary gear assembly, and a conical solar planetary gear assembly. The output end of the motor assembly is connected to the input end of the solar planetary gear assembly, and the output end of the solar planetary gear assembly is connected to the input end of the conical solar planetary gear assembly. This configuration, where the motor assembly drives the output, then the solar planetary gear assembly, and finally the conical solar planetary gear assembly, offers advantages such as high transmission efficiency, good anti-slip effect, high working power, and greater load capacity.

[0009] According to the above scheme, the solar planetary gear assembly includes a first-stage planetary gear set, a second-stage planetary gear set, and a gear ring. The first-stage and second-stage planetary gear sets are located side-by-side within the gear ring, and are meshed with the gear ring respectively. A gear is fixed to the output end of the motor assembly, meshing with the first-stage planetary gear set. A sun gear is fixed to the output end of the first-stage planetary gear set, meshing with the second-stage planetary gear set. The output end of the second-stage planetary gear set meshes with the conical solar planetary gear assembly. With this configuration, when the motor assembly outputs power, it first decelerates through the meshing of the gear with the first-stage planetary gear set to form the first-stage solar planetary gear set, then decelerates through the meshing of the sun gear with the second-stage planetary gear set to form the second-stage solar planetary gear set, and finally decelerates again through the conical solar planetary gear assembly to achieve a low-speed output.

[0010] According to the above scheme, the conical solar planetary gear assembly includes a conical gear set, a conical planetary carrier, conical planetary gears, and a conical gear ring. The output end of the secondary planetary gear set meshes with the conical gear set. A first conical gear is fixed to the output end of the conical gear set after passing through the gear ring. A third conical gear is fixed to the conical planetary carrier. The first and third conical gears mesh with each other, and the third conical gear meshes with the conical planetary gears. The conical planetary gears are located inside the conical gear ring and mesh with it. With this configuration, when the conical gear set rotates, it drives the third conical gear on the conical planetary carrier to rotate, and the rotation of the third conical gear drives the conical planetary gears to rotate.

[0011] According to the above scheme, the conical planetary carrier is vertically arranged. When the conical gear set drives the conical planetary carrier to rotate, it is in revolution. The conical planetary gear is inclined between the third conical gear and the ring conical gear, and rotates on its own axis. It also includes a stirring assembly, which includes a container and a stirring element movably disposed within the container. The conical planetary gear is connected to the stirring element, which is a curved stirring rod. With this arrangement, when the conical gear set rotates, it drives the conical planetary carrier to revolve, and the conical planetary carrier then drives the conical planetary gear to rotate on its own axis, thereby causing the curved stirring rod to form a 3D stirring trajectory. When stirring dough, it mimics the multi-faceted kneading of dough by hand, achieving a better stirring effect through multi-dimensional mixing by folding and turning around the dough.

[0012] According to the above scheme, the central axis of the conical planetary gear and the central axis of the conical planetary carrier form an angle of β°, and 20°≤β°≤40°.

[0013] According to the above scheme, the bevel gear three is formed with opposing upper and lower tooth grooves. The bevel gear one meshes with the upper tooth groove, and the lower tooth groove meshes with the bevel planetary gear. This arrangement, with opposing upper and lower tooth grooves on the bevel gear three, makes assembly more convenient.

[0014] According to the above scheme, a top output assembly is fixed on the bevel gear three. The top output assembly includes a connecting pipe with an output connection inner hole formed inside the connecting pipe. This configuration allows different accessories to be assembled on the top output assembly as needed, resulting in better performance.

[0015] According to the above scheme, the bevel gear three is meshed with a front output assembly, which includes a bevel gear two, and the upper tooth grooves of bevel gear two and bevel gear three are meshed together. This configuration allows for the assembly of different accessories to be fitted onto the front output assembly as needed, resulting in better performance.

[0016] According to the above scheme, the motor assembly includes a motor and a motor mounting bracket. The motor is fixed inside the rotating arm by the motor mounting bracket. The motor drive shaft includes a front output end and a rear output end. The front output end is fixedly connected to a gear, and the rear output end is fixed with a rear output component. This configuration allows for the assembly of different accessories as needed through the dual output ends, resulting in better performance.

[0017] According to the above scheme, the rotating arm is equipped with a gear adjustment component, which is electrically connected to the motor assembly; the main body is equipped with a knob for driving the rotating arm to rotate. This configuration allows for adjustment of the power output via the gear adjustment component, and the knob is used to fix the rotating arm in place after it has rotated a certain angle, facilitating the assembly of different working accessories.

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

[0019] This invention features a motor assembly that drives the output, which is then driven by a solar planetary gear assembly and finally by a bevel solar planetary gear assembly. This design offers advantages such as high transmission efficiency, good anti-slip effect, high working power, and greater load capacity. Attached Figure Description

[0032] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 10As shown, the kitchen center of this utility model includes a main body 1, on which a rotating arm 2 is provided. A power transmission mechanism 21 is provided within the rotating arm 2. The power transmission mechanism 21 includes a motor assembly, a solar planetary gear assembly, and a conical solar planetary gear assembly. The output end of the motor assembly is connected to the input end of the solar planetary gear assembly, and the output end of the solar planetary gear assembly is connected to the input end of the conical solar planetary gear assembly. This configuration, where the motor assembly drives the output, then the solar planetary gear assembly drives the output, and finally the conical solar planetary gear assembly drives the output, offers advantages such as high transmission efficiency, good anti-slip gear effect, high working power, and greater load capacity.

[0034] Furthermore, the solar planetary gear assembly includes a first-stage planetary gear set 213, a second-stage planetary gear set 214, and a gear ring 215. The first-stage planetary gear set 213 and the second-stage planetary gear set 214 are located side by side within the gear ring 215, and the first-stage planetary gear set 213 and the second-stage planetary gear set 214 are respectively meshed with the gear ring 215. A gear 2115 is fixed at the output end of the motor assembly, and the gear 2115 is meshed with the first-stage planetary gear set 213. A sun gear 2116 is fixed at the output end of the first-stage planetary gear set 213, and the sun gear 2116 is meshed with the second-stage planetary gear set 214. The output end of the second-stage planetary gear set 214 is meshed with the conical solar planetary gear assembly. With this configuration, when the motor assembly outputs power, it first meshes with the first-stage planetary gear set 213 through gear 2115 to form a first-stage sun planetary gear set for speed reduction, then meshes with the second-stage planetary gear set 214 through the sun gear 2116 to form a second-stage sun planetary gear set for speed reduction, and finally passes through the conical sun planetary gear assembly for speed reduction to achieve low-speed output.

[0035] In practical applications, the gear ring 215 has internal tooth grooves formed inside, which can respectively mesh with the first-stage planetary gear set 213 and the second-stage planetary gear set 214; wherein, the gear 2115 can be a helical gear or a spur gear, with helical gear transmission having lower noise, which is preferred.

[0036] Furthermore, the conical solar planetary gear assembly includes a bevel gear set 216, a conical planetary carrier 218, a conical planetary gear 219, and a conical gear ring 2110. The output end of the secondary planetary gear set 214 meshes with the bevel gear set 216. A first bevel gear 2161 is fixed to the output end of the bevel gear set 216 after passing through the gear ring 215. A third bevel gear 2181 is fixed to the conical planetary carrier 218. The first bevel gear 2161 meshes with the third bevel gear 2181, and the third bevel gear 2181 meshes with the conical planetary gear 219. The conical planetary gear 219 is located inside the conical gear ring 2110 and meshes with the conical gear ring 2110. With this configuration, when the bevel gear set 216 rotates, it drives the third bevel gear 2181 on the conical planetary carrier 218 to rotate, and the rotation of the third bevel gear 2181 drives the conical planetary gear 219 to rotate.

[0037] In practical applications, the bevel gear ring 2110 has an internal tooth groove 2 that meshes with the bevel planetary gear 219, and the internal tooth groove 2 is inclined.

[0038] Furthermore, the conical planetary carrier 218 is vertically arranged. When the bevel gear set 216 drives the conical planetary carrier 218 to rotate, it is in revolution. The conical planetary gear 219 is inclined between the bevel gear 2181 and the bevel gear ring 2110, and when the conical planetary gear 219 rotates, it is in rotation. It also includes a stirring assembly 3, which includes a container 31 and a stirring element 32 movably disposed within the container 31. The conical planetary gear 219 is connected to the stirring element 32, which is a curved stirring rod. With this arrangement, when the bevel gear set 216 rotates, it drives the conical planetary carrier 218 to revolve, and the conical planetary carrier 218 then drives the conical planetary gear 219 to rotate, thereby causing the curved stirring rod to form a 3D stirring trajectory (e.g., ...). Figure 2 As shown in the figure, when mixing dough, it imitates the multi-faceted kneading of dough by hand, and achieves better mixing effect by folding and mixing around the dough in multiple dimensions.

[0039] Furthermore, the central axis of the bevel planetary gear 219 forms an angle of β° with the central axis of the bevel planetary carrier 218, and 20°≤β°≤40°.

[0040] Furthermore, the bevel gear three 2181 is formed with an upper tooth groove 2182 and a lower tooth groove 2183 that are oppositely arranged. The bevel gear one 2161 meshes with the upper tooth groove 2182, and the lower tooth groove 2183 meshes with the bevel planetary gear 219. This arrangement, with the opposite upper tooth groove 2182 and lower tooth groove 2183 on the bevel gear three 2181, makes assembly more convenient.

[0041] Furthermore, a top output assembly 2111 is fixed on the bevel gear 3 2181. The top output assembly 2111 includes a connecting tube with an output connection inner hole formed inside the connecting tube. This configuration allows different accessories to be assembled on the top output assembly 2111 as needed, resulting in better performance.

[0042] Furthermore, the bevel gear three 2181 is meshed with a front output assembly 2112, which includes a bevel gear two 217 that meshes with the upper tooth groove 2182 of the bevel gear three 2181. This configuration allows for the assembly of different accessories to be fitted onto the front output assembly 2112 as needed, resulting in better performance.

[0043] Furthermore, the motor assembly includes a motor 211 and a motor mounting bracket 212. The motor 211 is fixed inside the rotating arm 2 via the motor mounting bracket 212. The drive shaft of the motor 211 includes a front output end and a rear output end. The front output end is fixedly connected to a gear 2115, and the rear output end is fixed with a rear output component 2113. This configuration allows for the assembly of different accessories as needed through the dual output ends, resulting in better performance.

[0044] In practical applications, the motor mounting bracket 212 is fixedly connected to the gear ring 215.

[0045] Furthermore, the rotating arm 2 is equipped with a gear adjustment component 23, which is electrically connected to the motor assembly; the main body 1 is equipped with a knob 11 for driving the rotating arm 2 to rotate. This configuration allows for adjustment of the power output via the gear adjustment component 23, while the knob 11, after driving the rotating arm 2 to rotate a certain angle, can be positioned and fixed, facilitating the assembly of different working accessories onto the rotating arm 2.

[0046] In practical applications, the rotating arm 2 comprises a housing consisting of a lower shell 22, a rear cover 24, an upper shell 25, and a top cover 26. The lower shell 22 and upper shell 25 are fixedly connected and form a cavity for accommodating the power transmission mechanism 21. The rear cover 24 is configured to correspond with the rear output assembly 2113. In use, opening the rear cover 24 allows for the assembly of the juice cup assembly 5 or other accessories requiring high-speed operation, such as a grinding cup assembly. This example uses the juice cup assembly but is not limited to it. It should be noted that since the rear output assembly 2113 is directly connected to the drive shaft of the motor 211, its output speed is the same as the drive shaft speed of the motor 211, without gear reduction, resulting in a high-speed output. The top cover 26 is mounted on the upper shell 25 and is connected to the top output assembly 2113. Component 2111 is configured accordingly. When in use, the top cover 26 can be opened to assemble the food processing cup component 4 or other accessories that require medium-speed operation, such as the orange juice cup component. Here, the food processing cup component is used as an example, but it is not limited to the food processing cup component. It should be noted that the top output component 2111 is driven and reduced in speed by a two-stage solar planetary gear assembly, resulting in a medium-speed output. The lower shell 22 has an opening formed on it. The stirring component 32 passes through the opening and is assembled on the conical planetary gear 219. The conical planetary gear 219 is driven and reduced in speed by a two-stage solar planetary gear assembly, and finally outputs at a low speed. The stirring component 32 can be equipped with different accessories, such as a dough hook, egg white stick, or a mixing paddle, to achieve the functions of stirring dough, beating egg whites, and mixing.

[0047] As an alternative, a front output component 2112 can be added, which rotates synchronously with the top output component 2111 to provide medium-speed output. It is understood that holes can be opened in the housing or a front cover can be added to facilitate the assembly of different accessories with the front output component 2112.

[0048] It should be noted that the kitchen center of this utility model has efficient transmission, high power output, 3D trajectory multi-dimensional efficient stirring, and can output three speeds: high, medium and low. The rotating arm 2 rotates around the main body 1, and different output components can be assembled with different accessories to achieve different functions.
