Abstract
Description
Technical Field
[0001] This application relates to the field of food processor technology, and more specifically, to a food processor. Background Technology
[0002] A food processor is a kitchen appliance used to process various ingredients. It typically consists of a main unit and a blending jar assembly attached to it. A shock-absorbing pad is placed between the main unit and the blending jar assembly to reduce vibration and noise. However, in some related technologies, this shock-absorbing pad is mounted on the main unit. When the blending jar assembly is removed from the main unit, the pad is exposed to the outside environment, affecting the aesthetics of the main unit and making it prone to detachment. Utility Model Content
[0003] This application provides a food processor that reduces the risk of the anti-vibration pad falling off.
[0004] A food processor, comprising:
[0005] Host;
[0006] A mixing cup assembly includes a mixing cup and a cup base cover disposed at the bottom of the mixing cup. The mixing cup is assembled to the main unit, and the cup base cover is provided with a snap-fit part.
[0007] A shock-absorbing pad is located between the bottom cover of the cup holder and the main unit. The shock-absorbing pad includes a main body part and a snap-fit part connected to each other. The snap-fit part and the snap-fit mating part are snap-fitted together.
[0008] The cup holder bottom cover and the main body are provided with a mounting groove, and the other is provided with a mounting rib, which is inserted into the mounting groove.
[0009] By adopting the above technical solution, since the shock-absorbing pad is snapped into the bottom cover of the blender cup assembly, the main unit can maintain its original appearance when the blender cup assembly is removed from the main unit. At the same time, because the shock-absorbing pad is installed on the bottom cover of the cup base, which is not easily visible to the user, its impact on the appearance of the blender cup assembly is also minimal. Furthermore, while the shock-absorbing pad and the bottom cover of the cup base are snapped together, the bottom cover of the cup base and the shock-absorbing pad also cooperate through mounting ribs and mounting grooves, which allows the shock-absorbing pad to be more securely installed on the bottom cover of the cup base, reducing the risk of the shock-absorbing pad shifting or falling off during the operation of the blender.
[0010] Optionally, the main body is provided with the mounting groove, and the cup base cover is provided with the mounting rib. It is easy to understand that the cup base cover typically needs to bear the weight of the blender cup and ingredients, and may be subjected to impact forces during the operation of the food processor. If a mounting groove is provided on the cup base cover, it may weaken the structural strength of the cup base cover, affecting its load-bearing capacity and stability. However, by placing the mounting groove in the shock-absorbing pad main body, the cup base cover only needs mounting ribs, which better maintains the structural integrity of the cup base cover, ensuring that it can stably support the blender cup assembly and reducing malfunctions and damage caused by structural problems with the cup base cover.
[0011] Optionally, the cup holder bottom cover is also provided with an anti-detachment rib, which is located outside the mounting rib and abuts against the outer wall of the main body.
[0012] Thus, the anti-detachment rib, located outside the mounting rib and abutting against the outer wall of the main body of the shock-absorbing pad, forms an additional barrier. Even when the food processor is subjected to significant vibration or external impact, the anti-detachment rib further restricts the shock-absorbing pad's movement, reducing the likelihood of it coming off the cup base cover and further improving the reliability of the connection.
[0013] Optionally, the anti-detachment rib is a semi-enclosed structure, covering the outer wall of the main body. The semi-enclosed structure of the anti-detachment rib can constrain the main body of the shock-absorbing pad from multiple directions, providing a stronger ability to prevent the shock-absorbing pad from detaching compared to simple contact. Even under complex operating conditions (such as severe vibrations caused by high-speed blending), the semi-enclosed anti-detachment rib can effectively prevent the shock-absorbing pad from shifting in any direction, ensuring that the shock-absorbing pad remains in the correct position and maintaining good vibration damping and noise reduction performance.
[0014] Optionally, the snap-fit part includes a snap fastener, the snap fastener having a free end and a snap-fit end, the snap-fit mating part including a snap hole and a snap-fit surface, the snap-fit surface being located on the side of the cup holder bottom cover away from the main unit, the free end passing through the snap hole, the radial dimension of the snap-fit end being larger than the diameter of the snap hole, and the snap-fit end abutting against the snap-fit surface.
[0015] Thus, because the radial dimension of the snap-fit end is larger than the diameter of the snap-fit hole, the snap-fit end is not easy to pass through the snap-fit hole. This can effectively prevent the anti-vibration pad from falling off due to vibration, ensuring that the anti-vibration pad is always in the correct position during use, thereby continuously playing the role of shock absorption and noise reduction, and improving the overall structural stability of the food processor.
[0016] Optionally, the main body includes a positioning surface facing the host side, and the host is provided with a positioning mating surface, the positioning surface and the positioning mating surface abutting and mating.
[0017] In this way, even if the shock-absorbing pad is installed on the bottom cover of the cup holder, the shock-absorbing pad can still be installed in the correct position of the main unit through the abutment and mating of the positioning surface and the positioning mating surface, so as to better perform the function of shock absorption and noise reduction.
[0018] Optionally, the positioning surface includes a connected bottom positioning surface and a side positioning surface, and the positioning mating surface includes a connected bottom positioning mating surface and a side positioning mating surface. The bottom positioning surface abuts against the bottom positioning mating surface, and the side positioning surface is fitted around the outer periphery of the side positioning mating surface.
[0019] In this way, the bottom positioning surface abuts against the bottom positioning mating surface, and the side positioning mating surface fits around the outer periphery of the side positioning surface. This dual positioning method makes the installation of the anti-vibration pad on the main unit more precise. The bottom positioning provides axial positioning, while the side positioning restricts radial displacement. The combination of the two effectively prevents the anti-vibration pad from moving in the axial and radial directions, ensuring that it is always in the correct position during the operation of the food processor and improving the stability of the overall structure.
[0020] Optionally, the main body also includes a mounting surface opposite to the bottom positioning surface, and the bottom cover of the cup holder is also provided with a mounting mating surface, the mounting surface being in contact with the mounting mating surface.
[0021] Optionally, the angle between the bottom positioning surface and the side positioning surface is greater than or equal to 90° and less than 180°.
[0022] Optionally, the number of the shock-absorbing pads is multiple, and the multiple shock-absorbing pads are distributed at intervals along the circumference of the cup seat bottom cover;
[0023] And / or, the number of the snap-fit parts is multiple, the number of the snap-fit mating parts is multiple, and the multiple snap-fit parts and the multiple snap-fit mating parts correspond one-to-one;
[0024] And / or, the shock-absorbing pad is made of a soft material. Attached Figure Description

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0037] This application provides a food processor. The food processor will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations can be combined with each other.
[0038] Please refer to the image. Figures 1 to 5The food processor includes a main unit 10, a blending cup assembly 20, and a shock-absorbing pad 30. The main unit 10 is the drive unit of the food processor, providing power to the food processor. The blending cup assembly 20 is the working unit of the food processor for processing food, using the power provided by the main unit 10 to cut, blend, etc., the food. For details, please refer to relevant technologies; this application will not elaborate on it.
[0039] The mixing cup assembly 20 includes a mixing cup 22 and a cup base cover 21. The mixing cup 22 is assembled to the main unit 10, and the cup base cover 21 is disposed at the bottom of the mixing cup 22. A shock-absorbing pad 30 is located between the cup base cover 21 and the main unit 10. The shock-absorbing pad 30 includes a connected main body portion 31 and a snap-fit portion 32. The cup base cover 21 has a snap-fit mating portion, and the snap-fit portion 32 engages with the snap-fit mating portion to mount the shock-absorbing pad 30 onto the cup base cover 21. Furthermore, one of the cup base cover 21 and the main body portion 31 has a mounting groove 311, and the other has a mounting rib 211, which is inserted into the mounting groove 311. That is, the main body portion 31 of the shock-absorbing pad 30 has the aforementioned mounting groove 311, and the cup base cover 21 has the aforementioned mounting rib 211; or, the main body portion 31 of the shock-absorbing pad 30 has the aforementioned mounting rib 211, and the cup base cover 21 has the aforementioned mounting groove 311.
[0040] As described above, the shock-absorbing pad 30 is snapped onto the cup base cover 21 of the blending cup assembly 20. When the blending cup assembly 20 is removed from the main unit 10, the main unit 10 can maintain its original appearance, avoiding any issues with the aesthetics of the main unit 10. Furthermore, since the shock-absorbing pad 30 is installed on the cup base cover 21, which is not easily visible to the user, its impact on the appearance of the blending cup assembly 20 is also minimal. In addition to the snap-fit engagement between the shock-absorbing pad 30 and the cup base cover 21, the cup base cover 21 and the shock-absorbing pad 30 also cooperate through the mounting rib 211 and the mounting groove 311. This ensures that the shock-absorbing pad 30 is more securely installed on the cup base cover 21, reducing the risk of displacement or detachment of the shock-absorbing pad 30 during the operation of the blender.
[0041] Please continue to refer to this. Figures 3 to 5 In one embodiment, the main body 31 of the shock-absorbing pad 30 is provided with the aforementioned mounting groove 311, and the cup holder bottom cover 21 is provided with the aforementioned mounting rib 211. In other words, the mounting groove 311 is formed in the main body 31 of the shock-absorbing pad 30, and the mounting rib 211 is formed in the cup holder bottom cover 21.
[0042] It's easy to understand that the cup base cover 21 typically needs to bear the weight of the blender cup 22 and ingredients, and may be subjected to certain impacts during the operation of the food processor. If a mounting groove 311 is provided on the cup base cover 21, it might weaken the structural strength of the cup base cover 21, affecting its load-bearing capacity and stability. However, by placing the mounting groove 311 on the main body 31 of the shock-absorbing pad 30, the cup base cover 21 only needs mounting ribs 211, which better maintains the structural integrity of the cup base cover 21, ensuring that it can stably support the blender cup assembly 20 and reducing malfunctions and damage caused by structural problems with the cup base cover 21.
[0043] In one specific embodiment, the mounting rib 211 extends circumferentially along the cup base cover 21 in an arc shape, and the mounting groove 311 is adapted to the mounting rib 211. The circumferential extension of the mounting rib 211 along the cup base cover 21 makes full use of the circumferential space of the cup base cover 21, achieving a stable connection and good shock absorption function without adding too many parts or occupying too much space. This helps to improve the compactness and rationality of the overall structure of the food processor, making the product appearance more concise and beautiful.
[0044] In one embodiment, there can be multiple shock-absorbing pads 30, which are distributed circumferentially along the bottom cover 21 of the cup holder to improve the shock absorption effect. The connection relationship of each shock-absorbing pad 30 can be referred to the above embodiment, and will not be repeated here.
[0045] like Figure 5 As shown, there are four shock-absorbing pads 30, which are evenly distributed around the circumference of the cup base cover 21.
[0046] Please refer to Figure 5 and Figure 9 In one embodiment, the cup holder bottom cover 21 is also provided with an anti-detachment rib 212, which is located outside the mounting rib 211 and abuts against the outer side wall of the main body 31.
[0047] Thus, the anti-detachment rib 212 is located outside the mounting rib 211 and abuts against the outer wall of the main body 31 of the shock-absorbing pad 30, forming an additional barrier. Even when the food processor is subjected to significant vibration or external impact, the shock-absorbing pad 30, in addition to the cooperation between the mounting groove 311 and the mounting rib 211, is further restricted by the anti-detachment rib 212, reducing the possibility of the shock-absorbing pad 30 detaching from the cup base cover 21 and further improving the reliability of the connection.
[0048] Furthermore, the anti-detachment rib 212 is a semi-enclosed structure, covering the outer wall of the main body 31. This semi-enclosed structure allows the anti-detachment rib 212 to constrain the main body 31 of the shock-absorbing pad 30 from multiple directions, providing a stronger ability to prevent the shock-absorbing pad 30 from detaching compared to simple contact. Even under complex operating conditions (such as severe vibrations caused by high-speed blending), the semi-enclosed anti-detachment rib 212 effectively prevents the shock-absorbing pad 30 from shifting in any direction, ensuring it remains in the correct position and maintaining good vibration damping and noise reduction performance. Simultaneously, since the shock-absorbing pad 30 has no external force points, users cannot easily apply external force to it, preventing accidental removal.
[0049] like Figure 5 As shown, the anti-detachment rib 212 includes a first part 2121 extending in the circumferential direction and two second parts 2122 extending in the radial direction. The second parts 2122 are connected to the ends of the first part 2121. The structure is simple and easy to manufacture.
[0050] Please refer to Figures 6 to 8 In one embodiment, there are multiple snap-fit parts 32 and multiple snap-fit mating parts. The multiple snap-fit parts 32 and multiple snap-fit mating parts correspond one-to-one, and the corresponding snap-fit parts 32 snap-fit with the snap-fit mating parts.
[0051] As shown in embodiment 7, there are two snap-fit parts 32. The two snap-fit parts 32 can reduce the structural complexity of the shock-absorbing pad 30, and at the same time can achieve a better snap-fit effect with the cup seat bottom cover 21.
[0052] In one embodiment, the snap-fit portion 32 has a free end 321 and a snap-fit end 322. The snap-fit mating portion includes a snap hole 213 and a snap-fit surface 214. The snap-fit surface 214 is located on the side of the base 11 away from the main unit 10. The free end 321 of the snap-fit portion 32 passes through the snap hole 213. The radial dimension of the snap-fit end 322 is larger than the diameter of the snap hole 213. The snap-fit end 322 abuts against the snap-fit surface 214.
[0053] Thus, because the radial dimension of the snap-fit end 322 is larger than the diameter of the snap-fit hole 213, the snap-fit end 322 is not easy to pass through the snap-fit hole 213. This effectively prevents the anti-vibration pad 30 from falling off due to vibration, ensuring that the anti-vibration pad 30 is always in the correct position during use, thereby continuously playing a role in shock absorption and noise reduction, and improving the overall structural stability of the food processor. It should be noted that when installing the anti-vibration pad 30, the free end 321 of the snap fastener should be aligned with the snap-fit hole 213 and inserted, so that the snap-fit end 322 deforms and also passes through the snap-fit hole 213, and abuts against the surface of the snap-fit hole 213.
[0054] Please refer to Figure 8 and Figure 9In one embodiment, the main body 31 includes a positioning surface facing the host 10, and the host 10 is provided with a positioning mating surface, and the positioning surface and the positioning mating surface abut against each other.
[0055] Thus, even if the shock-absorbing pad 30 is installed on the bottom cover 21 of the cup holder, the shock-absorbing pad 30 can still be installed in the correct position of the main unit 10 through the abutment and cooperation of the positioning surface and the positioning mating surface, so as to better perform the shock absorption and noise reduction function.
[0056] Furthermore, the positioning surface includes a bottom positioning surface 312 and a side positioning surface 313 connected together, and the positioning mating surface includes a bottom positioning mating surface 13 and a side positioning mating surface 14 connected together. The bottom positioning mating surface 13 overlaps the bottom positioning mating surface 313, and the side positioning mating surface 14 is fitted around the outer periphery of the side positioning surface 313.
[0057] The bottom positioning surface 312 abuts against the bottom positioning mating surface 13, and the side positioning mating surface 14 fits around the outer periphery of the side positioning surface 313. This dual positioning method makes the installation of the anti-vibration pad 30 on the main unit 10 more precise. The bottom positioning provides axial positioning, while the side positioning restricts radial displacement. The combination of the two effectively prevents the anti-vibration pad 30 from moving in the axial and radial directions, ensuring that it is always in the correct position during the operation of the food processor and improving the stability of the overall structure.
[0058] In one specific embodiment, the main unit 10 includes a base 11 and a panel 12, with the panel 12 mounted on top of the base 11. The top of the panel 12 includes the bottom positioning mating surface 13, and the side of the panel 12 includes the side positioning mating surface 14. That is, the bottom positioning mating surface 13 is formed on the top surface of the panel 12, and the side positioning mating surface 14 is formed on the side surface of the panel 12. However, this is not the only embodiment.
[0059] In one embodiment, the main body 31 further includes a mounting surface 314 opposite to the bottom positioning surface 312, and the cup holder bottom cover 21 also has a mounting mating surface 215, with the mounting surface 314 abutting against the mounting mating surface 215. The abutting between the mounting surface 314 and the mounting mating surface 215 increases the contact area between the shock-absorbing pad 30 and the cup holder bottom cover 21, making the connection between them tighter and more stable. Furthermore, when the cup holder bottom cover 21 is assembled onto the main unit 10, because the mounting surface 314 abuts against the mounting mating surface 215, and the bottom positioning surface 312 abuts against the bottom positioning mating surface 13 opposite to the mounting surface 314, the main body 31 is essentially sandwiched between the mounting mating surface 215 and the bottom positioning mating surface 13. This not only allows for more effective shock absorption but also enhances the connection stability between the shock-absorbing pad 30 and the main unit 10 and the cup holder bottom cover 21. During the operation of the food processor, this stable connection effectively prevents the shock-absorbing pad 30 from shifting or loosening.
[0060] In one embodiment, the angle between the bottom positioning surface 312 and the side positioning surface 313 is greater than or equal to 90° and less than 180°.
[0061] It is easy to understand that when the angle is less than 90°, the space formed by the side positioning surface 313 and the bottom positioning surface 312 becomes too narrow, making it difficult for the shock-absorbing pad 30 to be accurately placed on the bottom positioning mating surface 13 and the side positioning mating surface 14 of the main unit 10, increasing installation difficulty and reducing installation efficiency. When the angle is greater than 180°, the positioning effect of the side positioning surface 313 and the bottom positioning surface 312 is weakened, which is not conducive to shock absorption. Therefore, this solution forms a relatively open space structure between the side positioning surface 313 and the bottom positioning surface 312, which, while ensuring the positioning effect, also makes it easier to place the shock-absorbing pad on the bottom positioning mating surface 13 and the side positioning mating surface 14 of the main unit 10.
[0062] For example, the obtuse angle can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 175°, etc., but is not limited to this.
[0063] In one embodiment, the shock-absorbing pad 30 is made of a soft material to improve the shock absorption effect. The soft material includes, but is not limited to, silicone, rubber, or EVA (ethylene-vinyl acetate copolymer).
[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
