Description

Technical Field

[0001] The utility model relates to the field of food processors, and particularly to a cup body assembly with optimized sealing. Background Art

[0002] In the cup body assembly of the existing food processor, the glass cup body is usually fixedly connected with the lower cup base by screw threads. For example, in the solution disclosed in patent CN206462888U, the cup body is threadedly connected with the cup base. Since a section of the lower end of the cup body extends into the inner side of the cup base for screwing, when a sealing ring is arranged between the cup body and the cup base, the sealing ring can only be arranged between the top end of the cup base and the cup body. This sealing ring can only achieve axial sealing in the area above the top end of the cup base, resulting in poor sealing effect. When water flows down the outer wall of the cup body, it is easy to flow into the cup base through the position of the sealing ring, which is not conducive to the protection of the electrical components inside the cup base. Moreover, the soft contact area realized between the cup body and the cup base through the sealing ring is small, which is not conducive to the shock absorption of the cup body, and thus not conducive to reducing the working noise of the machine, reducing the user experience. Summary of the Utility Model

[0003] In order to solve the technical problem that in the solution of fixedly connecting the cup body and the cup base by screw threads in the prior art, the sealing effect between the cup body and the cup base is poor and water easily enters the inside of the cup base to damage the electrical components, the utility model provides a cup body assembly with optimized sealing. On the premise of optimizing the fixing method of the cup body and the cup base, a structurally optimized outer sealing ring is adopted to achieve double sealing between the cup body and the cup base, so as to improve the sealing effect.

[0004] A cup body assembly with optimized sealing disclosed by the utility model is applied to a food processor and includes an axially penetrating cup body, a heating plate arranged at the bottom opening of the cup body, and a cup base arranged below the cup body. The heating plate and the cup base are fixedly connected by screws and clamp the cup body up and down. An outer sealing ring is arranged between the cup body and the cup base. The cup base is provided with a step portion for supporting the bottom surface of the cup body. The outer sealing ring includes a first sealing portion clamped between the bottom surface of the cup body and the step portion and a second sealing portion clamped between the outer side wall of the cup body and the inner side wall of the cup base. The first sealing portion provides axial sealing between the cup body and the cup base, and the second sealing portion provides radial sealing between the cup body and the cup base.

[0005] The cup body assembly with optimized sealing of the utility model further has the following additional technical features:

[0006] The inner surface of the upper end of the second sealing portion fits with the outer side wall of the cup body to form an interference fit.

[0007] The second sealing portion includes a first sealing section extending vertically and connected in sequence from bottom to top and a second sealing section extending obliquely outwards. The cup base includes an inclined surface connected above the stepped portion and a supporting portion extending horizontally outwards from the top end of the inclined surface. The upper end of the second sealing section abuts against the supporting portion, and the lower end of the second sealing section abuts against the inclined surface.

[0008] The stepped portion includes a supporting surface and a limiting surface extending upwards from the supporting surface. A first rib is provided on one side of the first sealing section facing the limiting surface, and the first rib is in interference fit with the limiting surface; and / or, a second rib is provided on one side of the second sealing section facing the inclined surface, and the second rib is in interference fit with the inclined surface.

[0009] The second sealing section extends in an arc to adaptively fit the outer sidewall of the cup body.

[0010] The portion of the second sealing section disposed between the cup body and the supporting portion increases in thickness from the top downwards.

[0011] The stepped portion includes a supporting surface and a limiting surface extending upwards from the supporting surface. A third rib is provided on one side of the first sealing portion facing the supporting surface, and the third rib is in interference fit with the supporting surface.

[0012] A handle is provided on one side of the cup body, and an interference fit is formed between the outer surface of the upper end of a part of the second sealing portion and the inner wall surface of the handle.

[0013] A rotatable cutter shaft is fixedly penetrated through the center of the heating disc, and a cutter blade is provided on the cutter shaft. Taking the horizontal line where the top end of the outer sealing ring is located as the demarcation line, the area of the cup body above the demarcation line forms a visual area, and at least part of the cutter blade is higher than the demarcation line so that at least part of the cutter blade is located within the visual area.

[0014] An inner sealing ring is provided between the cup body and the heating disc, and the top end of the outer sealing ring is not lower than the top end of the inner sealing ring.

[0015] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0016] 1. For the optimized-sealing cup body assembly of the utility model, on the premise that the heating disc and the cup base clamp the cup body, there is a larger range for the outer sealing ring to extend between the cup body and the cup base, so that the outer sealing ring can provide double seals in the axial and radial directions between the cup body and the cup base, and can effectively prevent the water flowing down along the outer wall of the cup from entering the interior of the cup base, thus protecting the electrical components inside the cup base.

[0017] Meanwhile, two sealing parts in the axial and radial directions are provided between the cup body and the cup base, which can effectively disperse the fixing stress generated on the cup body due to the clamping and fixing among the heating plate, the cup base and the cup body, reduce the risk of the cup body breaking, and the flexible outer sealing ring can also reduce the vibration transmission of the cup body during operation and reduce the noise.

[0018] 2. As a preferred embodiment, an interference fit is formed between the inner surface of the upper end of the second sealing part and the outer side wall of the cup body. It can be understood that when the outer sealing ring is clamped in place, the inner surface of the upper end of the second sealing part is pressed against the outer side wall of the cup body after being compressed by the outer sealing ring, which can prevent dust and water droplets from entering the inside of the cup base along the inner gap between the surface of the cup body and the second sealing part and affecting the electrical components, which is beneficial to extending the service life of the whole machine and improving the use reliability of the whole machine.

[0019] 3. As a preferred embodiment, the second sealing part includes a first sealing section extending vertically and a second sealing section extending obliquely outwardly connected in sequence from bottom to top. The cup base includes an inclined surface connected above the step portion and a support portion extending horizontally outward from the top end of the inclined surface. The upper end of the second sealing section abuts against the support portion, and the lower end of the second sealing section abuts against the inclined surface. The shape of the second sealing part in this application can well adapt to the space between the cup body and the cup base. The second sealing part includes multiple sections of structures, which can not only improve the sealing effect, but also disperse the fixing stress generated by the clamping and fixing among the cup body, the cup base and the heating plate by forming multiple sections of contact with the cup body, which is beneficial to extending the service life of the outer sealing ring, and is also beneficial to reducing the vibration transmission of the cup body during operation and reducing the noise.

[0020] As a preferred embodiment under this embodiment, the step portion includes a support surface and a limiting surface extending upward from the support surface. A first convex rib is provided on one side of the first sealing section facing the limiting surface, and the first convex rib is in interference fit with the limiting surface. By providing the first convex rib, the assembly error in the radial direction can be reduced, and it can be ensured that both sides of the first sealing section are closely attached to the cup body and the limiting surface, and the interference fit between the first convex rib and the limiting surface can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring.

[0021] A second convex rib is provided on one side of the second sealing section facing the inclined surface, and the second convex rib is in interference fit with the inclined surface. By providing the second convex rib, the assembly error in the radial direction can be reduced, and it can be ensured that both sides of the second sealing section are closely attached to the cup body and the inclined surface, and the interference fit between the second convex rib and the inclined surface can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring.

[0022] 4. As a preferred embodiment, the second sealing section extends in an arc to adaptively fit the outer wall of the cup body. The second sealing section extending in an arc can better fit on the arc wall of the cup body, and can avoid the formation of a gap between the second sealing section and the outer wall of the cup body, thereby increasing the risk of water ingress.

[0023] 5. As a preferred embodiment, the thickness of the part of the second sealing section disposed between the cup body and the supporting part increases downward from the top of the second sealing section. In this embodiment, the thinner top of the second sealing section is beneficial for tightly fitting the outer wall of the cup body, and can avoid the formation of a gap between the second sealing section and the outer wall of the cup body, thereby increasing the risk of water ingress. At the same time, the position where the second sealing section abuts against the supporting part is thicker, which can ensure the effective contact between the second sealing section and the supporting part, avoid the formation of a gap between the two, and increase the risk of water ingress, thereby improving the sealing effect.

[0024] 6. As a preferred embodiment, the step portion includes a supporting surface and a limiting surface extending upward from the supporting surface. A third rib is provided on the side of the first sealing portion facing the supporting surface, and the third rib is in interference fit with the supporting surface. By providing the third rib, the interference fit between the third rib and the supporting surface can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring. Moreover, the reliability of the seal is increased, which can prevent dust and water droplets from entering the inside of the cup base and affecting the electrical components, which is beneficial to extending the service life of the whole machine and improving the reliability of the whole machine in use.

[0025] 7. As a preferred embodiment, a handle is provided on one side of the cup body, and an interference fit is formed between the upper outer surface of a part of the second sealing portion and the inner wall surface of the handle. Thus, it can prevent dust and water droplets from entering the inside of the cup base along the gap between the inner surface of the handle and the outer side of the second sealing portion and affecting the electrical components, which is beneficial to extending the service life of the whole machine and improving the reliability of the whole machine in use.

[0026] 8. As a preferred embodiment, a rotatable cutter shaft is fixedly penetrated through the center of the heating disc, and a cutter blade is provided on the cutter shaft. Taking the horizontal line where the top end of the outer sealing ring is located as the demarcation line, the area of the cup body above the demarcation line forms a visible area, and the cutter blade is at least partially higher than the demarcation line, so that at least part of the cutter blade is located in the visible area. By defining the demarcation line, the area above the demarcation line of the cup body forms a visible area, and the area below the demarcation line forms an occlusion area. By optimizing the position of the cutter blade so that at least part of the cutter blade is located in the visible area, the visual effect can be enhanced to assist the user in cleaning the cup body, improving the convenience of cleaning the cup body and enhancing the user experience.

[0027] As a preferred embodiment of this embodiment, an inner sealing ring is provided between the cup body and the heating plate, and the top end of the outer sealing ring is not lower than the top end of the inner sealing ring. This embodiment can prevent the inner sealing ring from blocking the interior and improve the visual effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Such as Figures 1 to 3As shown, the present application provides an optimized sealed cup assembly 10, which is applied to a food processor and includes an axially penetrating cup body 11, a heating plate 12 provided at the bottom opening of the cup body 11, and a cup base 13 provided below the cup body 11. The heating plate 12 and the cup base 13 are fixed by screws and clamp the cup body 11 up and down. An outer sealing ring 14 is provided between the cup body 11 and the cup base 13. The cup base 13 is provided with a step portion 15 for supporting the bottom surface of the cup body 11. The outer sealing ring 14 includes a first sealing portion 141 clamped between the bottom surface of the cup body 11 and the step portion 15 and a second sealing portion 142 clamped between the outer side wall of the cup body 11 and the inner side wall of the cup base 13. The first sealing portion 141 provides axial sealing between the cup body 11 and the cup base 13, and the second sealing portion 142 provides radial sealing between the cup body 11 and the cup base 13.

[0042] For the optimized sealed cup assembly 10 of the present application, on the premise that the heating plate 12 and the cup base 13 clamp the cup body 11, there is a larger range for the outer sealing ring 14 to extend between the cup body 11 and the cup base 13, so that the outer sealing ring 14 can provide double sealing along the axial and radial directions between the cup body 11 and the cup base 13, effectively preventing the water flowing down along the outer wall of the cup body 11 from entering the inside of the cup base 13, and thus protecting the electrical components inside the cup base 13. At the same time, two sealing portions in the axial and radial directions are provided between the cup body 11 and the cup base 13, which can effectively disperse the fixing stress generated on the cup body 11 due to the clamping and fixing among the heating plate 12, the cup base 13 and the cup body 11, reduce the risk of the cup body 11 being broken, and the flexible outer sealing ring 14 can also reduce the vibration transmission of the cup body 11 during operation and reduce noise.

[0043] As Figure 1 shown, since the threaded structure between the cup body 11 and the cup base 13 is omitted, the part of the lower end of the cup body 11 extending into the cup base 13 can be fully sealed to improve the sealing effect. As Figure 1 and Figure 2 shown, the cup base 13 is provided with a step portion 15, which can provide support for the bottom of the cup body 11. Specifically, the step portion 15 includes a support surface 151 and a limiting surface 152 extending upward from the support surface 151. The top of the heating plate 12 is provided with a flanging portion 121 extending outward. The approximately horizontal flanging portion 121 and the support surface 151 can ensure the fixing effect of the cup body 11 by clamping the cup body 11 up and down. Further, the support surface 151 can be used for arranging the first sealing portion 141, and the limiting surface 152 can be used for arranging part of the second sealing portion 142. On the premise of ensuring the fixing effect of the cup body 11, by optimizing the structure and position of the outer sealing ring 14, the sealing effect can be improved.

[0044] To fix the cup body 11, in one embodiment, screw posts extending downward are provided at the bottom of the heating plate 12, and screw holes corresponding to the screw posts are provided on the cup base 13. The heating plate 12 and the cup base 13 are fixed by a fastener passing through the screw holes and the screw posts, so that the heating plate 12 and the cup base 13 jointly clamp the cup body 11.

[0045] As a preferred embodiment, an interference fit is formed between the inner surface of the upper end of the second sealing portion 142 and the outer side wall of the cup body 11. It can be understood that when the outer sealing ring 14 is clamped in place, the inner surface of the upper end of the second sealing portion 142 is pressed against the outer side wall of the cup body 11 after being pressed by the outer sealing ring 14, which can prevent dust and water droplets from entering the inside of the cup base 13 along the gap between the surface of the cup body 11 and the inside of the second sealing portion 142 and affecting the electrical components, which is beneficial to extending the service life of the whole machine and improving the use reliability of the whole machine.

[0046] As Figure 2 shown, preferably, for the part of the top of the second sealing portion 142 located between the top surfaces of the cup body 11 and the cup base 13, its thickness increases from top to bottom. On the one hand, it is beneficial for the thinner upper part to closely adhere to the outer wall of the cup body 11, and on the other hand, it can ensure that the lower end abuts against the top surface of the cup base 13 to avoid forming a gap and increasing the risk of water ingress.

[0047] As a preferred embodiment, the second sealing portion 142 includes a first sealing section 143 extending vertically and a second sealing section 144 extending obliquely outward, which are connected in sequence from bottom to top. The cup base 13 includes an inclined surface portion 131 connected above the step portion 15 and a support portion 132 extending horizontally outward from the top end of the inclined surface portion 131. The upper end of the second sealing section 144 abuts against the support portion 132, and the lower end of the second sealing section 144 abuts against the inclined surface portion 131.

[0048] The shape of the second sealing portion 142 of the present application can well adapt to the space between the cup body 11 and the cup base 13. The second sealing portion 142 includes multiple sections of structures, which can not only improve the sealing effect, but also disperse the fixing stress generated by clamping and fixing among the cup body 11, the cup base 13 and the heating plate 12 due to multi-section contact with the cup body 11, which is beneficial to extending the service life of the outer sealing ring 14 and reducing the vibration transmission of the cup body 11 during operation and reducing noise.

[0049] As a preferred embodiment under this embodiment, the step portion 15 includes a support surface 151 and a limiting surface 152 extending upward from the support surface 151. A first rib 1431 is provided on one side of the first sealing section 143 facing the limiting surface 152, and the first rib 1431 and the limiting surface 152 are in interference fit.

[0050] As Figure 2As shown, by providing the first rib 1431, the assembly error in the radial direction can be reduced, ensuring that both sides of the first sealing section 143 are in close contact with the cup body 11 and the limiting surface 152. The interference fit between the first rib 1431 and the limiting surface 152 can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring 14.

[0051] As a preferred embodiment of this implementation manner, a second rib 1441 is provided on the side of the second sealing section 144 facing the inclined surface portion 131, and the second rib 1441 is in interference fit with the inclined surface portion 131.

[0052] As Figure 2 shown, by providing the second rib 1441, the assembly error in the radial direction can be reduced, ensuring that both sides of the second sealing section 144 are in close contact with the cup body 11 and the inclined surface portion 131. The interference fit between the second rib 1441 and the inclined surface portion 131 can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring 14.

[0053] As a preferred embodiment of this implementation manner, the second sealing section 144 extends in an arc to adaptively fit the outer side wall of the cup body 11. The arc-shaped extension of the second sealing section 144 can better fit the arc wall of the cup body 11, avoiding the formation of a gap between the second sealing section 144 and the outer wall of the cup body 11 and increasing the risk of water ingress.

[0054] As Figure 1 and Figure 2 shown, the outer wall of the cup body 11 includes a first straight wall section 111, an arc section 112, and a second straight wall section 113 from top to bottom. The side of the second sealing section 144 facing the cup body 11 has a curvature adapted to the arc section 112, which helps to strengthen the interference fit effect between the second sealing section 144 and the arc section 112. The first sealing section 143 is in interference fit with the second straight wall section 113.

[0055] As a preferred embodiment, the part of the second sealing section 144 provided between the cup body 11 and the support portion 132 increases in thickness from the top of the second sealing section 144 downward. In this embodiment, the thinner top of the second sealing section 144 is beneficial for tightly adhering to the outer wall of the cup body 11, avoiding the formation of a gap between the second sealing section 144 and the outer wall of the cup body 11 and increasing the risk of water ingress. At the same time, the position where the second sealing section 144 abuts against the support portion 132 is thicker, ensuring effective contact between the second sealing section 144 and the support portion 132, avoiding the formation of a gap between the two and increasing the risk of water ingress, and improving the sealing effect.

[0056] As Figure 2As shown in the figure, for the second sealing section 144 with the above-mentioned configuration, when water flows down the outer wall of the cup body 11, the water can flow downward along the outer side of the top of the second sealing section 144 and then cross the supporting portion 132 and flow downward along the outer side wall of the cup base 13, effectively preventing water from flowing into the cup base 13.

[0057] As a preferred embodiment, the step portion 15 includes a supporting surface 151 and a limiting surface 152 extending upward from the supporting surface 151. A third rib 1411 is provided on the side of the first sealing portion 141 facing the supporting surface 151, and the third rib 1411 is in interference fit with the supporting surface 151.

[0058] As Figure 2 shown in the figure, by providing the third rib 1411, the interference fit between the third rib 1411 and the supporting surface 151 can disperse the fixing stress, which is beneficial to extending the service life of the outer sealing ring 14; moreover, the sealing reliability is increased, and dust and water droplets can be prevented from entering the cup base 13 to affect the electrical components, which is beneficial to extending the service life of the whole machine and improving the use reliability of the whole machine.

[0059] As a preferred embodiment, a handle 16 is provided on one side of the cup body 11, and an interference fit is formed between the upper outer surface of a part of the second sealing portion 142 and the inner wall surface of the handle 16.

[0060] As Figure 3 shown in the figure, dust and water droplets can be prevented from entering the cup base 13 along the gap between the inner surface of the handle 16 and the outer side of the second sealing portion 142 to affect the electrical components, which is beneficial to extending the service life of the whole machine and improving the use reliability of the whole machine.

[0061] As a preferred embodiment, a rotatable cutter shaft 17 is fixedly penetrated through the center of the heating plate 12, and a cutter 18 is provided on the cutter shaft 17. Taking the horizontal line where the top end of the outer sealing ring 14 is located as the demarcation line, the area of the cup body 11 above the demarcation line forms a visible area, and the cutter 18 is at least partially higher than the demarcation line so that at least a part of the cutter 18 is located in the visible area.

[0062] In order to solve the technical problem that most or all of the cutters 18 of the crushing assembly in the prior art are located in the blind area of sight, resulting in the user being unable to view the cleaning condition of the cutter 18 from the side when cleaning the cup body 11, which makes the cleaning time-consuming and laborious, in this application, the position of the cutter 18 is optimized so that at least a part of the cutter 18 is located in the visible area, which can enhance the visual effect to assist the user in cleaning the cup body 11, improve the cleaning convenience of the cup body 11, and enhance the user experience. As Figure 1 shown in the figure, the position where the dotted line is located represents the position of the demarcation line.

[0063] As a preferred embodiment of this embodiment, an inner sealing ring 19 is provided between the cup body 11 and the heating plate 12, and the top end of the outer sealing ring 14 is not lower than the top end of the inner sealing ring 19.

[0064] As Figure 1 shown, this embodiment can prevent the inner sealing ring 19 from blocking the inside and improve the visual effect.

[0065] The technical solution protected by the present utility model is not limited to the above embodiments. It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, some modifications or improvements can be made to it on the basis of the present utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
