Description

Technical Field

[0001] This application belongs to the technical field of kitchen utensils, and particularly relates to a button assembly and a cooking appliance. Background Art

[0002] Existing cooking appliances, such as rice cookers or pressure cookers, generally include a pot body and a pot lid. The pot body is provided with a mounting hole, and an opening button assembly is provided at the mounting hole. The opening button assembly generally includes a button seat, a button cap, and a movable buckle linked to the button cap. The pot lid is provided with a fixed buckle. The button cap is movably arranged in the button seat. By pressing the button cap, the movable buckle is driven to act to release the locking between the movable buckle and the fixed buckle, so as to realize the opening operation of the cooking appliance. In order to reduce the shaking of the button cap during use, the existing button cap is generally just accommodated in the accommodating cavity of the button seat. Therefore, during the process of pressing the button cap, if the force application direction slightly deviates from the axis of the accommodating cavity, it will cause the pressing cap to contact the inner wall of the accommodating cavity and generate a large frictional force. The existence of this friction, on the one hand, will cause the button cap to move out of place, resulting in the swinging of the movable buckle not in place, so that the movable buckle and the fixed buckle cannot be separated, ultimately resulting in the obstruction of opening the lid. On the other hand, it will cause the button cap to be blocked from rebounding, that is, the button cap cannot return to the initial position after being pressed, so that when the pot lid is closed to the pot body, the movable buckle and the fixed buckle cannot be locked, ultimately resulting in the pot lid not being closed in place, affecting the realization of the cooking function. Summary of the Utility Model

[0003] This application provides a button assembly and a cooking appliance to solve the technical problem that the opening button structure of the existing cooking appliance is prone to jamming and not rebounding after being pressed.

[0004] The technical solution adopted by this application is as follows:

[0005] A button assembly includes a button seat having an accommodating cavity and a button cap movably arranged in the accommodating cavity. The button cap has a connected main body portion and an extension portion. Along the axis of the accommodating cavity, the extension portion is located outside the main body portion, and the outer diameter of the extension portion is greater than the outer diameter of the main body portion.

[0006] The button assembly described in this application further includes the following additional technical features:

[0007] The outer periphery of the extension portion protrudes outward along its circumferential direction to form a bulging portion.

[0008] The inside of the extension portion is hollow, so that one end of the main body portion is exposed to form a pressing end face.

[0009] The button cap further includes a trigger portion fixedly connected to the main body portion and extending inward. The button seat is provided with a guiding hole for the trigger portion to pass through.

[0010] The inner wall of the guiding hole is provided with a guiding surface, and the outer wall of the triggering part is provided with a mating surface. The angle between the guiding surface and the horizontal direction is greater than or equal to the angle between the mating surface and the horizontal direction.

[0011] The triggering part is provided with a cavity extending along its own axial direction, and the cavity has an open end facing the outside of the accommodating cavity.

[0012] The inner diameter of the cavity gradually increases from inside to outside.

[0013] The triggering part has a triggering end opposite to the open end, and the triggering end is provided with a through hole communicating with the cavity.

[0014] The button cap further includes an anti-rotation part fixedly connected to the main body part and extending inward. The button seat is provided with a limiting hole adapted to the anti-rotation part. The limiting hole is used to limit the rotation of the anti-rotation part along the circumferential direction of the button seat. The free end of the anti-rotation part is provided with an anti-detachment part, and the button seat is provided with a stop part that is in a stop fit with the anti-detachment part to limit the anti-rotation part from disengaging from the limiting hole.

[0015] The present application also discloses a cooking appliance, including a pot lid, a pot body, a movable buckle and a fixed buckle. The pot lid and the pot body are locked to each other through the movable buckle and the fixed buckle. The cooking appliance further includes the button assembly as described above. One of the pot lid and the pot body is provided with the button assembly and the movable buckle, and the other is provided with the fixed buckle. The button cap is used to drive the movable buckle to move so that the movable buckle is locked or unlocked with the fixed buckle.

[0016] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present application are as follows:

[0017] 1. By providing an extension part on the outside of the main body part in the present application, and the outer diameter of the extension part is greater than the outer diameter of the main body part, so that the gap between the extension part and the inner wall of the accommodating cavity is smaller than the gap between the main body part and the inner wall of the accommodating cavity. With such a setting, on the one hand, the appearance gap between the button cap and the inner wall of the accommodating cavity can be reduced, and the probability that external impurities enter the interior of the cooking appliance through the fitting gap between the two can be greatly reduced, effectively protecting the components inside the cooking appliance. On the other hand, the gap between the button cap and the inner wall of the accommodating cavity can reduce the probability of the button cap shaking during the moving process, enabling the button cap to smoothly slide, so that the button cap can smoothly switch between the initial position and the triggering position. Moreover, when the force application direction causes the button cap to contact the inner wall of the accommodating cavity during the moving process, due to the existence of the extension part and the relatively large outer diameter size of the extension part, the part in contact and friction with the inner wall of the accommodating cavity is limited to the extension part. Compared with the prior art, the friction area is greatly reduced, thereby reducing the frictional resistance and further reducing the probability of the button cap getting stuck.

[0018] 2. As a preferred embodiment of the present application, the outer periphery of the extension part protrudes outward along its circumferential direction to form a bulging part. The existence of the bulging part can further reduce the gap between the extension part and the inner wall of the accommodation cavity, thereby further narrowing the appearance gap and further reducing the probability of the button cap shaking during movement. In addition, when the force application direction causes the button cap to contact the inner wall of the accommodation cavity during movement, the setting of the bulging part can further reduce the contact area between the button cap and the inner wall of the accommodation cavity, reduce the frictional resistance of the inner wall of the accommodation cavity to the button cap, improve the user's operation feel, and enable the button cap to achieve its basic function. Moreover, the setting of the bulging part makes it easy to rebound due to its own structural properties when it is stressed. During the rebounding process, it can generate a pulling force on the main body part to assist the button cap in rebounding, greatly reducing the probability of the button cap being blocked during rebounding.

[0019] 3. As a preferred embodiment of the present application, the button cap further includes a triggering part fixedly connected to the main body part and extending inward. The setting method of the triggering part not only improves the overall structural strength and structural stability of the button cap, but also improves the coordination of the movement between the triggering part and the main body part. The button seat is provided with a guiding hole for the triggering part to pass through. The cooperation between the guiding hole and the triggering part can not only ensure that the triggering part moves along a predetermined path during pressing to achieve precise triggering and avoid misoperation, but also reduce the shaking or displacement of the button cap during use.

[0020] Furthermore, the inner wall of the guiding hole is provided with a guiding surface, and the outer wall of the triggering part is provided with a mating surface. The angle between the guiding surface and the horizontal direction is greater than or equal to the angle between the mating surface and the horizontal direction. By optimizing the angular relationship between the guiding surface and the mating surface, the friction force when the triggering part moves in the guiding hole can be reduced. This not only reduces the probability of the triggering part being worn and extends the service life of the triggering part, but also reduces the possibility of the triggering part getting stuck in the guiding hole, ensuring the smoothness of the triggering action, and thus ensuring the smooth reciprocating movement of the button cap. Moreover, the optimization of the angular matching relationship between the guiding surface and the mating surface can enable the button cap to maintain a relatively stable movement trajectory under the action of different pressing forces, improving the adaptability and reliability of the button assembly.

[0021] 4. As a preferred embodiment of the present application, the button cap further includes an anti-rotation part, and the button seat is provided with a limiting hole adapted to the anti-rotation part. The cooperation between the limiting hole and the anti-rotation part can limit the rotation of the button cap along the circumferential direction of the button seat. On the one hand, it enables the user to more precisely control the pressing direction and force when operating the button assembly, avoiding wrong operations caused by rotation. On the other hand, it can ensure that the button cap remains stable during use and will not deviate from the predetermined position due to rotation. In addition, by restricting the rotation of the button cap, the wear caused by rotational friction can also be reduced, which can not only extend the service life of the button cap and the button seat, but also prevent the button cap from getting stuck.

[0022] 5. The present application also discloses a cooking appliance. The pot lid and the pot body of the cooking appliance are unlocked through the button assembly in the present application. The smooth operation of the button cap in the present application enables the pot lid and the pot body of the cooking appliance to be smoothly unlocked, and the smooth return of the button cap enables the pot lid to be smoothly re-locked with the pot body when the pot lid is closed again. Both the locking action and the unlocking action are well guaranteed, improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0040] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that, without conflict, the embodiments of the present application and the features in each embodiment may be combined with each other.

[0041] In addition, in the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0042] In the present application, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or a communication; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "an embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] As Figure 1 , Figure 2 and Figure 6 shown, a button assembly includes a button base 1 having a receiving cavity 11 and a button cap 2 movably disposed in the receiving cavity 11. The button cap 2 has a connected main body portion 21 and an extension portion 22. Along the axial direction of the receiving cavity 11, the extension portion 22 is located outside the main body portion 21, and the outer diameter A of the extension portion 22 is greater than the outer diameter B of the main body portion 21.

[0045] Generally speaking, in order to achieve smooth sliding of the button cap 2, there is a clearance fit between the button cap 2 and the inner wall of the receiving cavity 11. However, an excessive clearance will, on the one hand, cause the button cap 2 to shake during pressing, affecting the user experience, and on the other hand, it will also lead to easy entry of external impurities. Therefore, during relevant design, the clearance between the button cap 2 and the inner wall of the receiving cavity 11 will be reduced as much as possible. With such a design, although the probability of the button cap 2 shaking is reduced, during pressing, due to uneven application of force, the outer surface of the button cap 2 is likely to come into contact with the inner wall of the receiving cavity 11, thereby generating frictional resistance and affecting the sliding of the button cap 2.

[0046] In this application, an extension part 22 is arranged outside the main body part 21, and the outer diameter of the extension part 22 is larger than that of the main body part 21, so that the gap between the extension part 22 and the inner wall of the receiving cavity 11 is smaller than the gap between the main body part 21 and the inner wall of the receiving cavity 11. With such a setting, on the one hand, the appearance gap between the button cap 2 and the inner wall of the receiving cavity 11 can be reduced, and the probability that external impurities enter the interior of the cooking appliance through the fitting gap between the two can be greatly reduced, effectively protecting the components inside the cooking appliance. On the other hand, the gap between the button cap 2 and the inner wall of the receiving cavity 11 can reduce the probability of the button cap 2 shaking during movement, enabling the button cap 2 to slide smoothly, so that the button cap 2 can smoothly switch between the initial position and the trigger position. Moreover, when the force application direction causes the button cap 2 to contact the inner wall of the receiving cavity 11 during movement, due to the existence of the extension part 22 and the relatively large outer diameter size of the extension part 22, the part in contact and friction with the inner wall of the receiving cavity 11 is limited to the extension part 22. Compared with the prior art, the friction area is greatly reduced, thereby reducing the frictional resistance and further reducing the probability of the button cap 2 getting stuck.

[0047] In this application, the structure of the extension part can adopt any one of the following implementation manners:

[0048] Embodiment 1: The outer periphery of the extension part is an equal-diameter structure from the inside to the outside. That is, along the axial direction of the receiving cavity 11, the outer diameters of each part of the extension part are equal. With such a setting, the design of the extension part can be simplified, facilitating the processing and forming of the extension part.

[0049] Embodiment 2: As shown in Figure 2 、 Figure 5 and Figure 6 , the outer periphery of the extension part 22 bulges outward along its circumferential direction to form a bulging part 221. The existence of the bulging part 221 can further reduce the gap between the extension part 22 and the inner wall of the receiving cavity 11, thereby further narrowing the appearance gap and further reducing the probability of the button cap 2 shaking during movement. In addition, when the force application direction causes the button cap 2 to contact the inner wall of the receiving cavity 11 during movement, the setting of the bulging part 221 can further reduce the contact area between the button cap 2 and the inner wall of the receiving cavity 11, reduce the frictional resistance of the inner wall of the receiving cavity 11 on the button cap 2, improve the user's operation feel, and enable the button cap 2 to achieve its basic function. Moreover, the setting of the bulging part 221 makes it easy to rebound due to its own structural properties when it is stressed, and the pulling force generated on the main body part 21 during the rebound process can assist the button cap 2 to rebound, greatly reducing the probability of the button cap 2 being blocked during rebound.

[0050] In the second embodiment, the structural design of the bulging part 221 can adopt any one of the following embodiments:

[0051] Embodiment 1: A ring-shaped rib is provided along the circumferential direction of the outer periphery of the extension part, and this ring-shaped rib constitutes the bulged part.

[0052] Embodiment 2: As Figure 6 shown, the outer periphery of the extension part 22 bulges outwards to form a bulged part 221 with a changing radius of curvature. The bulged part 221 has multiple different radii of curvature, and the minimum outer diameter of the bulged part 221 is greater than the outer diameter of the main body part 21. The multiple different radii of curvature enable the bulged part 221 to have a position with the largest outer diameter. During the pressing process, when the button cap 2 abuts against the inner wall of the receiving cavity 11, the abutting part first exists at the largest outer diameter of the bulged part 221 (as Figure 2 shown at point E). Compared with the technical solutions where the entire extension part 22 or the entire button cap 2 abuts against the receiving cavity 11, in this Embodiment 2, the contact area between the button cap 2 and the inner wall of the receiving cavity 11 can be further reduced, thereby reducing the frictional force and further decreasing the probability of the button cap 2 getting stuck and not rebounding.

[0053] Whether it is Embodiment 1 or Embodiment 2, the extension part 22 can further adopt any one of the following structural designs in the following embodiments:

[0054] Embodiment 3: The extension part is a solid structure, and the outer end face of the extension part constitutes the pressing end face. During the pressing process, the button cap is driven to move by pressing this pressing end face.

[0055] Embodiment 4: As Figure 1 、 Figure 2 and Figure 6 shown, the inside of the extension part 22 is hollow, so that one end of the main body part 21 is exposed to form a pressing end face 211. The inside of the extension part 22 is hollow, so that the extension part 22 itself has better flexibility. On the one hand, when the extension part 22 abuts against the inner wall of the receiving cavity 11 during the pressing process, the extension part 22 is easily deformed, thereby reducing the obstruction to the movement of the button cap 2. On the other hand, during the rebounding process of the button cap 2, because the extension part 22 is easily deformed, when the extension part 22 returns to the state before extrusion, it can simultaneously generate a pulling force on the main body part 21 to assist the main body part 21 in resetting, further reducing the probability of the button cap 2 getting stuck and not rebounding.

[0056] As a preferred embodiment of the present application, as Figure 1 、 Figure 2 and Figure 5As shown, the button cap 2 further includes a trigger portion 23 fixedly connected to the main body portion 21 and extending inwardly. The button base 1 is provided with a guiding hole 12 for the trigger portion 23 to pass through. The arrangement of the trigger portion 23 not only improves the overall structural strength and structural stability of the button cap 2, but also enhances the coordination of the movement between the trigger portion 23 and the main body portion 21. The guiding hole 12 provided on the button base 1 and the cooperation between the guiding hole 12 and the trigger portion 23 can not only ensure that the trigger portion 23 moves along a predetermined path during pressing, achieve precise triggering and avoid misoperation, but also reduce the shaking or displacement of the button cap 2 during use.

[0057] Furthermore, as Figure 5 shown, the trigger portion 23 is provided at the central portion of the main body portion 21, so that when the trigger portion 23 touches the object to be triggered, the reverse force of the trigger object on the trigger portion 23 can act on the main body portion 21 evenly, avoiding the offset of the button cap 2.

[0058] As a preferred embodiment under this embodiment, as Figures 3 to 6 shown, the inner wall of the guiding hole 12 is provided with a guiding surface 121, and the outer wall of the trigger portion 23 is provided with a mating surface 233. The angle C between the guiding surface 121 and the horizontal direction is greater than or equal to the angle D between the mating surface 233 and the horizontal direction. By optimizing the angular relationship between the guiding surface 121 and the mating surface 233, the friction force when the trigger portion 23 moves in the guiding hole 12 can be reduced. This not only reduces the probability of wear of the trigger portion 23 and extends the service life of the trigger portion 23, but also reduces the possibility of jamming of the trigger portion 23 in the guiding hole 12, ensuring the smoothness of the triggering action, and thus ensuring the smooth reciprocating movement of the button cap 2. Moreover, the optimization of the angular cooperation relationship between the guiding surface 121 and the mating surface 233 can enable the button cap 2 to maintain a relatively stable movement trajectory under the action of different pressing forces, improving the adaptability and reliability of the button assembly.

[0059] Furthermore, the angle C between the guiding surface 121 and the horizontal direction is greater than 98°, and the angle D between the mating surface 233 and the horizontal direction is greater than 95°. Thus, during the movement of the button cap 2, even if the trigger portion 23 contacts and rubs against the guiding hole 12 (as shown at the F position in Figure 2 ), the contact area between the trigger portion 23 and the inner wall of the guiding hole 12 can be further reduced, reducing the frictional resistance of the button base 1 on the button cap 2, enabling the button cap 2 to smoothly switch between the initial position and the trigger position, and ensuring the stability and reliability of the realization of its function.

[0060] In this embodiment, for the specific structural design of the trigger portion, any one of the following embodiments can be adopted:

[0061] Embodiment 5: The trigger portion is a solid structure.

[0062] Example 6: As Figure 6 shown, the trigger part 23 is provided with a cavity 231 extending along its own axial direction, and the cavity 231 has an open end facing the outside of the accommodation cavity 11. The arrangement of the cavity 231 and the setting of its open end thereon enable, in case the button cap 2 gets stuck and does not rebound during use, a tool to be inserted into the cavity 231 to conveniently pull the button cap 2 back to the initial position.

[0063] As a preferred example under this Example 6, as Figure 6 shown, the inner diameter of the cavity 231 gradually increases from inside to outside. With such a setting, on the one hand, it can provide sufficient space for the intervention of the tool and ensure that the trigger part 23 has sufficient structural strength. On the other hand, in the implementation where the button cap 2 is an injection molded part, such a design of the cavity 231 helps with demolding, which not only helps improve the processing efficiency of the button cap 2 but also helps improve the yield rate of the processed button cap 2.

[0064] During the movement of the button cap 2, when the trigger part 23 comes into contact and friction with the inner wall of the guiding hole 12, the contact and friction part will occur at a relatively inner part of the trigger part 23 along the axial direction of the accommodation cavity 11. Therefore, as a preferred example under this Example 6, as Figure 6 shown, the trigger part 23 has a trigger end opposite to the open end, and the trigger end is provided with a through hole 232 communicating with the cavity 231. The setting of the through hole 232 can improve the flexibility of the trigger part 23 on the side close to the trigger end. Thus, when the trigger part 23 comes into contact and friction with the inner wall of the guiding hole 12, the hard extrusion between the two is reduced. On the one hand, it can improve the service life of both, and on the other hand, it can improve the self - adaptive adjustment ability of the button cap 2 when contact and friction occur, reducing the probability of the button cap 2 getting stuck.

[0065] As a preferred embodiment under this implementation manner, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the button cap 2 further includes an anti - rotation part 24 fixedly connected to the main body part 21 and extending inward, and the button seat 1 is provided with a limiting hole 13 adapted to the anti - rotation part 24. The limiting hole 13 is used to limit the rotation of the anti - rotation part 24 along the circumferential direction of the button seat 1. With such a setting, on the one hand, it enables the user to more precisely control the pressing direction and force when operating the button assembly, avoiding incorrect operations caused by rotation. On the other hand, it can ensure that the button cap 2 remains stable during use and will not deviate from the predetermined position due to rotation. In addition, by restricting the rotation of the button cap 2, the wear caused by rotational friction can also be reduced, which can not only extend the service life of the button cap 2 and the button seat 1 but also prevent the button cap 2 from getting stuck.

[0066] Furthermore, asFigures 1 to 6 As shown, a retaining portion 25 is provided at the free end of the anti-rotation portion 24, and the button base 1 is provided with a retaining portion 14 that engages with the retaining portion 25 to prevent the anti-rotation portion 24 from disengaging from the limiting hole 13. By providing the retaining portion 25 at the free end of the anti-rotation portion 24, the function of the anti-rotation portion 24 can be more integrated. While achieving anti-rotation, it can also achieve anti-disengagement, ensuring that the button cap 2 will not disengage from the receiving cavity 11 during the rebound process, and avoiding the loss of the button cap 2.

[0067] In a specific example, as Figure 5 shown, a plurality of anti-rotation portions 24 are provided at intervals along the circumferential direction of the main body portion 21 of the button cap 2, thereby improving the stability of the structure and movement of the button cap 2.

[0068] This application also discloses a cooking appliance, including a pot lid 5, a pot body 6, a movable buckle 3, and a fixed buckle 4. The pot lid 5 and the pot body 6 are locked to each other through the movable buckle 3 and the fixed buckle 4. It further includes the above button assembly. One of the pot lid 5 and the pot body 6 is provided with the button assembly and the movable buckle 3, and the other is provided with the fixed buckle 4. The button cap 2 is used to drive the movable buckle 3 to move so that the movable buckle 3 is locked or unlocked with the fixed buckle 4.

[0069] As Figure 7 and Figure 8 shown, it gives a specific example of arranging the button assembly and the movable buckle 3 on the pot body 6 and arranging the fixed buckle 4 on the pot lid 5. By adopting the button assembly in this application, the pot lid 5 and the pot body 6 of the cooking appliance can be smoothly unlocked, and the smooth return of the button cap 2 enables the pot lid 5 to be smoothly re-locked with the pot body 6 when the pot lid 5 is covered on the pot body 6 again. Both the locking action and the unlocking action are well guaranteed, improving the user experience.
