[0006] As set forth above, since the oil collecting box is located below the planetary gear assembly, and the normal projection of the planetary gear assembly on the oil collecting cavity is in the cavity opening, if lubricating oil of the planetary gear assembly flows out, the flowed-out lubricating oil will flow into the oil collecting cavity.

The amount of lubricating oil will not be too much, and in addition, lubricating oil is viscous. Although the oil collecting box will be driven together with the mixing element, lubricating oil will not be thrown out from the oil collecting box, so that lubricating oil will not pollute the food processor and / or food materials.

[0007] In some embodiments, the planetary gear assembly includes a sun gear, a planet gear and a ring gear, the sun gear and the planet gear are located in the ring gear. The sun gear serves as an input end of the planetary gear assembly, the planet gear serves as an output end of the planetary gear assembly; the diameter of the ring gear is smaller than the diameter of the cavity opening to realize that the normal projection of the planetary gear assembly is located in the cavity opening.

[0008] As set forth above, based on the configuration of the planetary gear assembly, the planetary gear assembly has simple structure, simple transmission relationship, low noise and low cost. In combination, the diameter of the gear ring is smaller than the diameter of the cavity opening, and the food processor has simple structure, low cost and low noise.

[0009] In some embodiments, the planetary gear assembly is inserted into the oil collection cavity from the cavity opening.

[0010] As set forth above, since the planetary gear assembly is inserted into the oil collection cavity from the cavity opening, the lubricating oil flowing out of the planetary gear assembly directly flows into the oil collection cavity and cannot flow out of the cavity opening due to centrifugal force or the like, and the food processor and / or food materials are not contaminated.

[0011] In some embodiments, a plurality of partitions are arranged in the oil collection cavity, each of the partitions is lower than the cavity opening, and the oil collection cavity is divided into a plurality of independent sub-oil collection cavities.

[0012] As set forth above, the oil collection cavity is divided into a plurality of independent sub-oil collection cavities, the sub-oil collection cavities can collect lubricating oil, and the lubricating oil is blocked in the sub-oil collection cavities during rotation of the planetary gear assembly, so that the lubricating oil cannot flow out and contaminate the food processor and / or food materials.

[0013] In some embodiments, the plurality of sub-oil collection cavities form a grid.

[0014] As set forth above, the plurality of sub-oil collection cavities form a grid, and the partitions can act as reinforcing plates to enhance the strength of the oil collection box under the premise of meeting the oil collection function.

[0015] In some embodiments, the oil collection cavity is provided with a mounting portion, the food processor includes a support in the mounting portion, the stirring member and the support are connected to the output end of the planetary gear assembly, the oil collection cavity includes an oil collection cavity wall, the partitions include first partitions and second partitions, the first partitions are arranged along the radial direction of the oil collection cavity, the second partitions are arranged along the circumferential direction of the oil collection cavity, and the first partitions, the second partitions, the mounting portion and the oil collection cavity wall cooperate to divide the oil collection cavity into at least two rings of sub-oil collection cavities.

[0016] As set forth above, since the first partitions, the second partitions, the mounting portion and the oil collection cavity wall cooperate to divide the oil collection cavity into at least two rings of sub-oil collection cavities, the circumferential direction and the radial direction of the oil collection cavity are supported, the structural strength of the oil collection box is higher, and at least two rings of sub-oil collection cavities can better collect lubricating oil flowing out of the planetary gear assembly to prevent the lubricating oil from contaminating the food processor and / or food materials.

[0017] In some embodiments, the oil collecting cavity is provided with a mounting portion; the food processor comprises a support located in the mounting portion, the stirring member and the support are both connected with the output end of the planetary gear assembly; the oil collecting cavity comprises an oil collecting cavity bottom wall, the mounting portion comprises a mounting portion bottom wall, and the oil collecting cavity bottom wall is curved upwards relative to the mounting portion bottom wall.

[0018] With the above arrangement, since the oil collecting cavity bottom wall is curved upwards relative to the mounting portion bottom wall, on the one hand, the curved oil collecting cavity bottom wall is stronger and is less likely to be deformed during production, and on the other hand, the oil collecting cavity bottom wall is curved upwards, so that the lubricating oil flows to a lower position, facilitating the collection of lubricating oil and preventing the lubricating oil from flowing out of the oil collecting cavity.

[0019] In some embodiments, the food processor comprises four bearings and a transmission shaft; the support comprises two bearing mounting holes; one bearing is mounted at the top end and the bottom end of each bearing mounting hole respectively; the transmission shaft is arranged through the two bearings mounted in one bearing mounting hole, and the two ends of the transmission shaft are connected with the stirring member and the output end of the planetary gear assembly respectively; and the motor shaft of the motor is arranged through the two bearings mounted in the other bearing mounting hole.

[0021] In some embodiments, the food processor comprises a housing for assembling the motor, the housing comprises a receiving cavity, the planetary gear assembly extends out of the receiving cavity, and the receiving cavity comprises a receiving cavity wall, which is blocked between the planetary gear assembly and the oil collecting cavity wall of the oil collecting cavity.

[0022] With the above arrangement, during the operation of the food processor, if the oil collecting cavity collects lubricating oil and the lubricating oil moves in the direction of the dashed arrow, the receiving cavity wall is blocked between the planetary gear assembly and the oil collecting cavity wall of the oil collecting cavity in the movement path of the lubricating oil, thereby preventing the lubricating oil from flowing out of the oil collecting cavity, so that the lubricating oil flows back to the oil collecting cavity, and thus the lubricating oil can better avoid contaminating the food processor and / or food materials.

[0023] In some embodiments, the shell comprises a wall around the containing cavity to form an insertion cavity, the oil collecting box comprises an oil collecting cavity wall enclosing the oil collecting cavity; the depth of the oil collecting cavity wall inserted into the insertion cavity is at least 1 / 2 of the height of the oil collecting cavity wall, and a gap is formed between the oil collecting cavity wall and the wall.

[0024] As set forth above, since the depth of the oil collecting cavity wall inserted into the insertion cavity is at least 1 / 2 of the height of the oil collecting cavity wall, if there is lubricating oil flowing out without being blocked by the containing cavity wall, the flowing-out oil will stay on the inner surface of the wall, thereby, it is beneficial to avoid the flowing-out lubricating oil from polluting the food processor and / or food materials. In addition, the insertion of the oil collecting box into the insertion cavity is equivalent to the hiding of the oil collecting box in the wall, which not only can reduce the height of the whole structure of the oil collecting box and the shell, but also can make the food processor more beautiful.

[0033] Referring to Figure 1 , Figure 3 and Figure 4 , the application discloses a food processor.

In addition, the food processor of the application further comprises a base 6 and a machine shell 7. The base 6 comprises a seat body 61 and a stand column 62 standing on the seat body 61. The machine shell 7 comprises a shell body 71 and a cover body 72. The shell body 71 and the cover body 72 are covered to form a containing cavity. The containing cavity is used to contain the planetary gear assembly 3, the motor 4 and the like, so that the machine shell 7, the planetary gear assembly 3 and the motor 4 and the like constitute a machine head. The machine shell 7 is rotationally connected with the stand column 62 through the shell body 71, so that the machine head can be flipped in a first direction in a vertical plane until a horizontal direction to be connected with the stirring piece 2, and then the motor 4 can drive the stirring piece 2 to rotate in the stirring bowl 1. The machine head is flipped (head-up) in a second direction opposite to the first direction, and then the stirring piece 2 and the like can be taken out. The stirring piece 2 is not limited, for example, the stirring piece 2 is a dough hook.

[0034] Referring to Figures 1 to 3 , the oil collecting box 5 comprises an oil collecting cavity 51. The oil collecting cavity 51 is used to collect the lubricating oil flowing out of the planetary gear assembly 3, and the effect can be achieved. The oil collecting box 5 is connected to the output end of the planetary gear assembly 3 and is located below the planetary gear assembly 3. How to be located below is not limited, as long as the normal projection of the planetary gear assembly 3 on the oil collecting cavity 51 is located in the cavity opening 50 of the oil collecting cavity 51 when the lubricating oil flowing out of the planetary gear assembly 3 can flow into the oil collecting cavity 51.

[0035] The stirring member 2 is connected to the output end of the planetary gear assembly 3, is located below the oil collecting box 5, and is located in the stirring bowl 1. The motor 4 is connected to the input end of the planetary gear assembly 3, drives the planetary gear assembly 3 to rotate, and the planetary gear assembly 3 drives the oil collecting box 5 and the stirring member 2 to rotate. Based on the action of the planetary gear assembly 3, the structure of the planetary gear assembly 3 is not limited, and in some embodiments, the planetary gear assembly 3 includes a sun gear 31, a planet gear 32, and a ring gear 33. The ring gear 33 is stationary, the sun gear 31 is the input of the planetary gear assembly 3, the motor 4 drives the sun gear 31 to rotate, the planet gear 32 is the output of the planetary gear assembly 3, and is driven by meshing with the sun gear 31 and the ring gear 33, and the planet gear 32 drives the oil collecting box 5 and the stirring member 2 to rotate.

[0036] As described above, since the oil collecting box 5 is located below the planetary gear assembly 3, and the orthographic projection of the planetary gear assembly 3 on the oil collecting cavity 51 is in the cavity opening 50, if the planetary gear assembly 3 has lubricating oil flowing out, the flowing-out lubricating oil will flow into the oil collecting cavity 51. In various embodiments of the present application, the flowing-out lubricating oil is the lubricating oil flowing out during the operation of the planetary gear assembly 3, and the amount of lubricating oil will not be too much, and the lubricating oil is viscous. Although the oil collecting box 5 will be driven together with the stirring member 2, the lubricating oil will not be thrown out of the oil collecting box, so that the lubricating oil will not contaminate the food processor and / or the food materials.

[0037] The planetary gear assembly 3 has any structure to make the orthographic projection in the cavity opening 50. In some embodiments, the planetary gear assembly 3 includes a sun gear 31, a planet gear 32, and a ring gear 33. The sun gear 31 and the planet gear 32 are located in the ring gear 33. The planet gear 32 directly meshes with the sun gear 31 and the ring gear 33, and there can be other components between them to achieve meshing. The sun gear 31 is the input of the planetary gear assembly 3, and the planet gear 32 is the output of the planetary gear assembly 3. The diameter of the ring gear 33 is smaller than the diameter of the cavity opening 50 to realize that the orthographic projection of the planetary gear assembly 3 is located in the cavity opening 50.

[0038] As described above, based on the structure of the planetary gear assembly 3, the planetary gear assembly 3 has a simple structure, a simple transmission relationship, low noise, and low cost. In combination, the diameter of the ring gear 33 is smaller than the diameter of the cavity opening 50, and the food processor has a simple structure, low cost, and low noise.

[0039] Referring to Figure 2 , Figure 1 and Figure 3 , the planetary gear assembly 3 is inserted into the oil collecting cavity 51 from the cavity opening 50. Figure 3 The depth of the insertion is d.

[0040] As set forth above, since the planetary gear assembly 3 is inserted into the oil collecting cavity 51 from the cavity opening 50, the lubricating oil flowing out of the planetary gear assembly 3 directly flows into the oil collecting cavity 51 and cannot flow out of the cavity opening 50 due to centrifugal force or the like, and is even less likely to contaminate the food processor and / or food materials.

[0041] Referring to Figure 5 , the oil collecting cavity 51 is provided with a plurality of partitions 52. Figure 5 Six partitions are shown, but the number of partitions 52 is not limited. Each of the partitions 52 is lower than the cavity opening 50 to divide the oil collecting cavity 51 into a plurality of mutually independent sub-oil collecting cavities 511. The shape of the plurality of sub-oil collecting cavities 511 is not limited, and the number of sub-oil collecting cavities 511 is also not limited. Figure 5 Six sub-oil collecting cavities 511 are shown.

[0042] As set forth above, the oil collecting cavity 51 is divided into a plurality of mutually independent sub-oil collecting cavities 511, which not only can collect lubricating oil, but also can block the lubricating oil in the sub-oil collecting cavities 511 during rotation of the planetary gear assembly 3, so that the lubricating oil is even less likely to flow out and contaminate the food processor and / or food materials.

[0043] Referring to Figure 5 , the plurality of sub-oil collecting cavities 511 form a grid.

[0044] As set forth above, the plurality of sub-oil collecting cavities 511 form a grid, and the partitions 52 can act as reinforcing plates to enhance the strength of the oil collecting box 5 on the premise that the oil collecting box 5 meets the oil collecting function.

[0045] Referring to Figure 2 and Figure 5 , the oil collecting cavity 51 is provided with a mounting portion 53. The food processor includes a bracket 54 located in the mounting portion 53. The bracket 54 and the stirring member 2 are connected to the output end of the planetary gear assembly 3, including: a) the stirring member 2 and the bracket 54 are connected to the output end of the planetary gear assembly 3 through a transmission shaft 55. Referring to Figure 1 , Figure 2 and Figure 4 , the bracket 54 is penetrated by and connected to the transmission shaft 55, one end of the transmission shaft 55 is connected to the output end of the planetary gear assembly 3, and the other end is connected to the stirring member 2. For the a embodiment, the number of bearings 56 between the bracket 54 and the transmission shaft 55 can also be two; b) the bracket 54 is connected to the output end of the planetary gear assembly 3, and the stirring member 2 is connected to the bracket 54.

[0046] Referring to Figure 5The oil collecting cavity 51 comprises an oil collecting cavity wall 512, and the partition plate 52 comprises a first partition plate 521 and a second partition plate 522. The first partition plate 521 is arranged along the radial direction of the oil collecting cavity 51, and specifically, the first partition plate 521 is connected to the mounting portion 53 and the oil collecting cavity wall 512 along the radial direction of the oil collecting cavity 51. The second partition plate 522 is distributed along the circumferential direction of the oil collecting cavity 51, and the circumferential distribution comprises an arc surface of the second partition plate 522 which can be concentric with the oil collecting cavity wall 512 or can not be concentric with the oil collecting cavity wall 512. Specifically, two ends of some second partition plates 522 are respectively connected to adjacent first partition plates 521, and two ends of other second partition plates 522 are respectively connected to the mounting portion 53 and the oil collecting cavity wall 512. In this way, the first partition plate 521, the second partition plate 522, the mounting portion 53 and the oil collecting cavity wall 512 cooperate to divide the oil collecting cavity 51 into at least two sub-oil collecting cavities 511. There are six sub-oil collecting cavities 511 in total, but the number is not limited thereto.

[0047] As described above, since the first partition plate 521, the second partition plate 522, the mounting portion 53 and the oil collecting cavity wall 512 cooperate to divide the oil collecting cavity 51 into at least two sub-oil collecting cavities 511, the circumferential direction and the radial direction of the oil collecting cavity 51 are supported, and the structural strength of the oil collecting box 5 is higher. At the same time, the at least two sub-oil collecting cavities 511 can also better collect the lubricating oil flowing out of the planetary gear assembly 3, so as to prevent the lubricating oil from polluting the food processor and / or the food materials.

[0048] Referring to Figure 4 , Figure 5 and in combination with Figure 2 , the mounting portion 53 is provided with a mounting cavity 531. The support 54 is located in the mounting cavity 531, and the support 54 and the inner wall of the mounting cavity 531 constitute a rotation-stopping structure. How to constitute the rotation-stopping structure is not limited, for example, the mounting cavity 531 is oval, and the support 54 is also oval. When the support 54 is located in the mounting cavity 531, the oval shapes cooperate to constitute the rotation-stopping structure. For another example, the support 54 is square, and the mounting cavity 531 is also square. The square shapes cooperate to constitute the rotation-stopping structure.

[0049] As described above, the rotation-stopping structure is constituted by the support 54 and the inner wall of the mounting cavity 531, which more conveniently enables the stirring member 2 and the oil collecting box 5 to be driven by the planetary gear assembly to rotate synchronously.

[0050] Referring to Figure 2 and Figure 3The oil collecting cavity 51 comprises an oil collecting cavity bottom wall 513, and the mounting portion 53 comprises a mounting portion bottom wall 533. The oil collecting cavity bottom wall 513 is curved upward relative to the mounting portion bottom wall 533. That is, the bottom wall of the oil collecting box 5 comprises the oil collecting cavity bottom wall 513 and the mounting portion bottom wall 533. In this embodiment, the shape of the inside of the oil collecting cavity 51 is not limited to a grid.

[0051] As set forth above, since the oil collecting cavity bottom wall 513 is curved upward relative to the mounting portion bottom wall 533, on the one hand, the curved oil collecting cavity bottom wall 513 is stronger because it is curved, and the oil collecting box 5 is not easily deformed during production. On the other hand, the oil collecting cavity bottom wall is curved upward, lubricating oil flows to a lower position, lubricating oil is easily collected, and lubricating oil is prevented from flowing out of the oil collecting cavity 51.

[0052] Referring to Figure 2 , an embodiment in which the support 54 and the stirring member 2 are both connected to the output end of the planetary gear assembly 3 is described as follows. The food processor comprises four bearings 56 and a transmission shaft 55. Referring to Figure 6 , the support 54 comprises two bearing mounting holes 541. One of the bearings 56 is mounted at the top end and the bottom end of each of the bearing mounting holes 541. The transmission shaft 55 passes through the two bearings 56 mounted in one of the bearing mounting holes 541, and the two ends of the transmission shaft 55 are connected to the stirring member 2 and the output end of the planetary gear assembly 3, i.e., the planetary gear 32. The motor shaft 41 of the motor 4 passes through the two bearings 56 mounted in the other one of the bearing mounting holes 541.

[0053] As set forth above, since the transmission shaft 55 passes through the two bearings 56 mounted in one of the bearing mounting holes 541, and the two ends of the transmission shaft 55 are connected to the stirring member 2 and the output end of the planetary gear assembly 3; and the motor shaft 41 of the motor 4 passes through the two bearings 56 mounted in the other one of the bearing mounting holes 541, the forces on the motor shaft 41 and the transmission shaft 55 are uniform, the stirring member 2 rotates smoothly, and the stability is better.

[0054] Referring to Figure 2 and Figure 4 , the food processor comprises a housing 71 for assembling the motor 4. The housing 71 comprises a receiving cavity, and the planetary gear assembly 3 extends out of the receiving cavity. The receiving cavity comprises a receiving cavity wall 711, and the receiving cavity wall 711 is blocked between the planetary gear assembly 3 and the oil collecting cavity wall 512 of the oil collecting cavity 51.

[0055] As set forth above, in the working process of the food processor, if the oil collection cavity 51 collects lubricating oil and the lubricating oil moves in the direction of the dashed arrow, the accommodation cavity wall 711 is blocked between the planetary gear assembly 3 and the oil collection cavity wall 512 of the oil collection cavity 51 on the movement path of the lubricating oil, blocks the flow of the lubricating oil out of the oil collection cavity 51, and makes the lubricating oil flow back to the oil collection cavity 51, so that the lubricating oil can better avoid contaminating the food processor and / or food materials.

[0056] Referring to Figure 2 and Figure 4 , the shell 71 includes a surrounding wall 712 which forms an insertion cavity 713 around the accommodation cavity. The oil collection box 5 includes an oil collection cavity wall 512 which surrounds the oil collection cavity 51. The insertion depth of the oil collection cavity wall into the insertion cavity is at least 1 / 2 of the height of the oil collection cavity wall, such as Figure 2 h / H≥1 / 2, for example, 0.5, 0.52, 0.55, 0.58, 0.6, 0.65, 0.7, 0.72, 0.75, 0.78, 0.8, 0.83, 0.85, 0.88, 0.9, 0.93, 0.95, 0.98 or 1. After insertion, a gap is formed between the oil collection cavity wall and the surrounding wall.

[0057] As set forth above, since the insertion depth of the oil collection cavity wall into the insertion cavity is at least 1 / 2 of the height of the oil collection cavity wall, if the lubricating oil flows out without being blocked by the accommodation cavity wall 711, the flowing-out oil will remain on the inner surface of the surrounding wall 712, thereby facilitating the avoidance of contamination of the food processor and / or food materials by the flowing-out lubricating oil. In addition, the insertion of the oil collection box 5 into the insertion cavity 732, which is equivalent to the hiding of the oil collection box 5 in the surrounding wall 731, not only reduces the height of the whole constituted by the oil collection box 5 and the shell 71, but also makes the food processor more beautiful.

[0058] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
