[0031] Embodiment 1
[0032] Figure 1 Shows a schematic cross-sectional structure diagram of the food processor in Embodiment 1 of the present utility model. Figure 2 Shows a partial enlarged view of the food processor at position A in Embodiment 1 of the present utility model. Please refer to Figure 1 and Figure 2, A cooking machine, comprising a cup body 2, a cup cover 3 covering the cup body 2, a rotating shaft 6 extending into the cup body 2, and a main machine 1 connected to the rotating shaft 6. The rotating shaft 6 is rotatably connected to the bottom of the cup body 2 to enhance the stability of the rotation of the rotating shaft 6. A blade 64 is provided on the rotating shaft 6, and a first sealing ring 4 is provided between the rotating shaft 6 and the cup cover 3. The first sealing ring 4 includes a sealing ring body 41 sleeved on the rotating shaft 6 and an outer edge portion 42 connected to the sealing ring body 41, and the outer edge portion 42 extends around the sealing ring body 41 for one week. Wherein, the outer edge portion 42 is provided with a first rib 43 and a second rib 44 facing the cup cover 3, and the first rib 43 and the second rib 44 respectively extend around the sealing ring body 41 for one week. The first rib 43 and the second rib 44 abut against the cup cover 3, so that the inside of the main machine 1 and the cup body 2 are isolated. Specifically, the first rib 43 and the second rib 44 form two seals between the rotating shaft 6 and the cup cover 3. The medium in the cup body 2 needs to pass through the gap between the cup cover 3 and the first rib 43, and then pass through the gap between the cup cover 3 and the second rib 44 to enter the inside of the main machine 1, reducing the probability of the medium seeping into the main machine 1 and ensuring the sealing performance between the cup cover 3 and the rotating shaft 6. The first sealing ring 4 contacts the cup cover 3 through the first rib 43 and the second rib 44, and the contact area between the first sealing ring 4 and the cup cover 3 is small. During the rotation of the rotating shaft 6, the resistance between the cup cover 3 and the rotating shaft 6 is small. At the same time, the first sealing ring 4 does not improve the structure of the cup cover 3, saving the production cost.
[0033] The specific structures of the first sealing ring 4 and the cup cover 3 are described as follows:
[0034] Please refer to Figure 1 and Figure 2 , the outer edge portion 42 is arranged horizontally. The first rib 43 and the second rib 44 extend upward and respectively contact the lower surface of the cup cover 3 to seal the cup cover 3 and the rotating shaft 6. A fourth extension portion 34 extends downward from the lower surface of the cup cover 3, and the fourth extension portion 34 extends into the second rib 44. The fourth extension portion 34 increases the flow path of the medium when it seeps into the main machine 1, and the first extension portion 34 also plays a role in blocking the medium to enhance the sealing effect. When the second rib 44 is impacted or extruded by the medium, the second rib 44 elastically deforms toward the fourth extension portion 34, and the second rib 44 contacts the fourth extension portion 34. The fourth extension portion 34 can limit the deformation range of the second rib 44 to prevent the second rib 44 from completely separating from the cup cover 3 and losing the sealing effect.
[0035] Figure 3 Fig. shows a partial enlarged view of the cooking machine at B in the first embodiment of the present invention. Please refer to Figure 1 、 Figure 2 and Figure 3, the lid 3 is provided with a first extension portion 31 extending outwardly. The first extension portion 31 contacts the upper end surface of the cup body 2, facilitating the placement of the lid 3 on the cup body 2. A second extension portion 32 is provided on the lid 3 below the first extension portion 31. The second extension portion 32 faces the inner wall of the cup body 2. A second sealing ring 5 is provided between the first extension portion 31 and the second extension portion 32 to fix the position of the second sealing ring 5. Additionally, a third extension portion 33 is provided on the lid 3 below the second extension portion 32. The third extension portion 33 points to the inner wall of the cup body 2. The second extension portion 32 and the third extension portion 33 can isolate most of the medium in the cup body 2, reducing the sealing pressure of the second sealing ring 5. The second extension portion 32 and the third extension portion 33 do not contact the cup body 2, and the second extension portion 32 and the third extension portion 33 will not interfere with the cup body 2 and will not increase the resistance when the rotating shaft 6 rotates.
[0036] Exemplarily, the second extension portion 32 and the third extension portion 33 can contact the cup body 2. At this time, the sealing performance of the second extension portion 32 and the third extension portion 33 is better.
[0037] The specific structures of the second sealing ring 5 and the rotating shaft 6 are described as follows:
[0038] Please refer to Figure 3 , one end of the second sealing ring 5 is connected to the cup body 2; the other end of the second sealing ring 5 extends successively along the first extension portion 31, the lid 3 and the second extension portion 32; the other end of the second sealing ring 5 contacts the inner wall of the cup body 2. The second sealing ring 5 forms multiple bends during the extension process to form two seals. When the lid 3 is closed on the cup body 2, the arc portion 51 deforms and fits more closely to the first extension portion 31, the lid 3 and the second extension portion 32 to ensure the sealing performance.
[0039] Figure 4 The three-dimensional structural schematic diagram of the rotating shaft in the food processor in the first embodiment of the present invention is shown. Please refer to Figure 4 , a flat portion 63 is provided on the surface of the rotating shaft 6. The flat portion 63 contacts the sealing ring body 41. The first sealing ring 4 can be conveniently fixed on the rotating shaft 6 through the flat portion 63. Two flat portions 63 are provided, and the two flat portions 63 are provided on the opposite sides of the rotating shaft 6. When the first sealing ring 4 is installed on the rotating shaft 6, the first sealing ring 4 contacts the flat portion 63. Since the flat portion 63 is a plane, it forms a restriction on the first sealing ring 4, increasing the stability of the connection between the first sealing ring 4 and the rotating shaft 6.
[0040] The specific working process of this embodiment is as follows:
[0041] When the cooking machine is working, the medium inside the cup body 2 continuously impacts the gaps between the cup lid 3 and the rotating shaft 6, and between the cup lid 3 and the cup body 2. When the medium impacts the gap between the cup lid 3 and the rotating shaft 6, it is successively blocked by the first rib 43 and the second rib 44. When the medium impacts the second rib 44, the second rib 44 elastically deforms towards the fourth extension 34, and the fourth extension 34 can limit the deformation range of the second rib 44 to prevent the second rib 44 from completely separating from the cup lid 3 and losing the sealing effect. At the same time, the fourth extension 34 increases the flow path of the medium when it penetrates into the main body 1, and the fourth extension 34 also plays a role in blocking the medium. When the medium impacts the gap between the cup lid 3 and the cup body 2, the second extension 32 and the third extension 33 first block most of the medium inside the cup body 2, reducing the sealing pressure of the second sealing ring 5. Then the second sealing ring 5 respectively fits against the first extension 31, the cup lid 3, and the second extension 32 to block the remaining medium.
[0042] Embodiment 2
[0043] Figure 5 Fig. shows a schematic cross-sectional structure diagram of the cooking machine in Embodiment 2 of the present utility model. Figure 6 Fig. shows a partial enlarged view of the cooking machine at C in Embodiment 2 of the present utility model. Please refer to Figure 5 and Figure 6 Based on Embodiment 1, Embodiment 2 discloses a first sealing ring 4. A through hole 35 is provided on the cup lid 3, and the rotating shaft 6 passes through the through hole 35. The outer edge portion 42 extends into the through hole 35, the first rib 43 contacts the inner wall of the through hole 35, and the upper side of the second rib 44 contacts the lower surface of the cup lid 3.
[0044] Exemplarily, the cup lid 3 at the through hole 35 extends downward to form a fourth extension 34, and the upper side of the second rib 44 contacts the lower surface of the fourth extension 34.
[0045] Two seals are formed between the rotating shaft 6 and the cup lid 3 through the first rib 43 and the second rib 44. However, the outer edge portion 42 is arranged along the axial direction of the rotating shaft 6. During the rotation of the rotating shaft 6, a small range of displacement in the up and down directions occurs, and the outer edge portion 42 is always clamped between the cup lid 3 and the rotating shaft 6 to form an effective seal. The displacement of the rotating shaft 6 will not affect the seal of the outer edge portion 42, and the sealing performance of the outer edge portion 42 is more stable.
[0046] Please refer to Figure 6 As shown in, a sleeve 62 is also sleeved on the rotating shaft 6, and a cleaning knife 61 is provided on the sleeve 62. The cleaning knife 61 can be various known models of cleaning knives 61 in the art. The upper end of the sleeve 62 is clamped between the first sealing ring 4 and the rotating shaft 6 to enhance the connection stability between the cleaning knife 61 and the rotating shaft 6 and ensure that the cleaning knife 61 and the rotating shaft 6 rotate synchronously. At this time, the lower part of the flat position 63 contacts the sleeve 62, and the upper part of the flat position 63 contacts the sealing ring body 41.
[0047] It can be seen that in the above-mentioned cooking machine, the first rib position 43 and the second rib position 44 form two seals between the rotating shaft 6 and the cup cover 3, ensuring the sealing performance between the cup cover 3 and the rotating shaft 6. At the same time, the contact area between the first sealing ring 4 and the cup cover 3 is small, and the resistance between the cup cover 3 and the rotating shaft 6 is small during the rotation of the rotating shaft 6.
[0048] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0049] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
