Description

Technical Field

[0001] This utility model belongs to the field of cooking utensil technology, specifically relating to a pressure cooker lid. Background Technology

[0002] Pressure cookers are a common cooking appliance in kitchens. When cooking food, pressure cookers increase the pressure inside the pot, thereby raising the heating temperature, improving heating efficiency, or making food cook more easily. A pressure cooker mainly consists of a pot body and a lid. To ensure a tight connection between the lid and the pot body, a clamp-type pressure cooker has been developed. Specifically, turning a knob causes a linkage component to clamp or release the lid and pot body. However, this current method of adjusting the clamps by turning a knob lacks feedback mechanisms (such as sound or vibration), failing to provide a better user experience. Utility Model Content

[0003] This utility model provides a pressure cooker lid, which aims to solve the problem that the existing clamp-type pressure cooker lids, which adjust by turning a knob to drive the clamps to tighten or loosen, lack an adjustment feedback mechanism, resulting in a poor user experience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A pressure cooker lid, comprising:

[0006] The pot lid body is surrounded by a clamping assembly for clamping or releasing the pot lid body;

[0007] A knob is rotatably mounted on the pot lid body, and a linkage component is provided between the knob and the clamp assembly. This linkage component converts the rotational movement of the knob into an opening and closing movement of the clamp assembly, clamping or releasing the pot lid body.

[0008] An adjustment feedback component is disposed between the knob and the lid body. The adjustment feedback component includes a plurality of protrusions arranged around the rotation direction of the knob and an elastic abutment, with a recess between two adjacent protrusions. The plurality of protrusions are located on the knob and the elastic abutment is located on the lid body; or, the plurality of protrusions are located on the lid body and the elastic abutment is located on the knob. When the knob is rotated, the elastic abutment generates adjustment feedback by alternately sliding over the protrusions and the recess.

[0009] A further embodiment: the plurality of protrusions are a plurality of ribs provided on the knob, and the elastic abutment includes an abutment provided on the lid body and an elastic member provided between the abutment and the lid body for driving the abutment against the knob.

[0010] Based on the above solution: by setting several ribs, abutments, and elastic elements, when the knob is turned, the abutments slide past the ribs at different positions in sequence under the action of the ribs and elastic elements, thereby producing sound, which can bring a better user experience.

[0011] A further embodiment: The pot lid body is provided with a first mounting groove, the abutment and the elastic element are both located in the first mounting groove, and the elastic element is located between the abutment and the bottom wall of the first mounting groove.

[0012] Based on the above technical solution, the above settings result in better stability when the knob is turned to drive the clamping assembly to clamp or release.

[0013] A further embodiment: the end of the abutment near the knob is tapered.

[0014] Based on the above technical solution: the tapered end design facilitates smooth sliding into and out of the groove between the raised ribs when the knob is turned, making the feedback ("click-click" sound) clearer and smoother, while reducing wear and extending service life.

[0015] A further embodiment: the clamp assembly includes two clamps arranged opposite each other, and the linkage assembly includes:

[0016] Two crossbars are connected to two clamps respectively, and the two crossbars are slidably mounted on the pot lid body along the opening and closing direction of the clamps; and,

[0017] Two drive columns, the upper ends of which are inserted into the knob, and the lower ends of which are respectively inserted into the two crossbars. The pot lid body is provided with arc-shaped guide holes that cooperate with the two drive columns respectively.

[0018] When the knob is turned, the knob drives the two clamps to clamp or release the pot lid body via the drive column and the crossbar.

[0019] Based on the above technical solution: the rotary motion of the knob is converted into the linear motion of the clamp, the transmission path is direct and efficient, making operation less strenuous, and the overall structure is very compact, which is conducive to the thin design of the pot lid.

[0020] A further solution: The pot lid body is provided with a panel located on the upper side of the two crossbars, and an elastic gasket is provided between the panel and each of the crossbars.

[0021] Based on the above technical solution: the setting of the elastic pad effectively reduces the friction between the crossbar and the panel, thereby reducing wear and ensuring that the clamp assembly can still slide flexibly and smoothly during long-term use, thus improving the reliability and lifespan of the product.

[0022] A further embodiment: The lower side of the panel is provided with two connecting parts for connecting to the pot lid body, and each elastic pad is located between its corresponding connecting part and the crossbar.

[0023] A further embodiment: The panel is provided with a knob mounting groove, the knob is rotatably mounted in the knob mounting groove, and both of the arc-shaped guide holes are located on the bottom wall of the knob mounting groove.

[0024] A further embodiment: The knob includes a handwheel and a rotating part located below the handwheel. The handwheel and the rotating part are fixedly connected. The handwheel is provided with a first anti-fooling part, and the rotating part is provided with a second anti-fooling part that cooperates with the first anti-fooling part.

[0025] Based on the above technical solution, the foolproof structure ensures that the handwheel and the connecting part can only be assembled in the one correct relative position, fundamentally avoiding transmission failures caused by assembly errors, and improving production efficiency and product quality.

[0026] A further solution: the first anti-mistake part includes a plurality of protrusions arranged around the handwheel, and the second anti-mistake part includes a plurality of anti-mistake grooves arranged around the rotating part, and the plurality of protrusions and the plurality of anti-mistake grooves correspond one-to-one.

[0027] The beneficial effects of this utility model are as follows:

[0028] In this invention, a knob and a linkage component are incorporated. The linkage component converts the rotational motion of the knob into the opening and closing motion of the clamping component, thereby clamping or releasing the lid body. An adjustment feedback component, comprising several protrusions arranged around the rotation direction of the knob and elastic abutments, is provided between the knob and the lid body. During knob rotation, the elastic abutments generate audible or tactile feedback by sequentially sliding over different protrusions, providing a better user experience. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1 to 3 As shown, this embodiment provides a pressure cooker lid, including:

[0042] The pot lid body 2 is surrounded by a clamping 4 assembly for clamping or releasing the pot lid body 2;

[0043] A knob 1 is rotatably mounted on the pot lid body 2, and a linkage component is provided between the knob 1 and the clamping clamp 4 assembly. This linkage component converts the rotational movement of the knob 1 into the opening and closing movement of the clamping clamp 4 assembly, which clamps or releases the pot lid body 2.

[0044] An adjustment feedback component is disposed between the knob 1 and the pot lid body 2. The adjustment feedback component includes several protrusions arranged around the rotation direction of the knob 1 and an elastic abutment. A recess is provided between two adjacent protrusions. The protrusions are located on the knob 1 and the elastic abutment is located on the pot lid body 2; or, the protrusions are located on the pot lid body 2 and the elastic abutment is located on the knob 1. When the knob 1 is rotated, the elastic abutment generates adjustment feedback by alternately sliding over the protrusions and recesses. Specifically, the adjustment feedback is a tactile sensation or sound transmitted from the knob 1 to the user's hand, thereby providing a better user experience.

[0045] In some specific implementations, such as Figure 3 , Figure 5 and Figure 6 As shown, the plurality of protrusions are a plurality of raised ribs 122 provided on the knob 1, and the elastic abutment includes an abutment portion 226 provided on the lid body 2 and an elastic element 227 provided between the abutment portion 226 and the lid body 2 for driving the abutment portion 226 to abut against the knob 1. Specifically, the elastic element 227 is a spring.

[0046] In order to facilitate the installation of the abutment 226 and the elastic element 227 and thus make them stably cooperate with the rib 122, this embodiment provides a first mounting groove 225 with the opening facing upward on the pot lid body 2. The abutment 226 and the elastic element 227 are both located in the first mounting groove 225, and the elastic element 227 is located between the abutment 226 and the bottom wall of the first mounting groove 225.

[0047] In order to facilitate the smooth sliding of the abutment 226 into and out of the groove between the ribs 122 when the knob 1 is rotated, the end of the abutment 226 near the knob 1 is tapered.

[0048] In some specific implementations, such as Figure 2 and Figure 3 As shown, as a specific structure of the linkage component, the clamp 4 component includes two arc-shaped clamps 4 arranged opposite each other. When the lid body 2 is placed on the pot body 3, the two arc-shaped clamps 4 clamp the lid body 2 and the pot body 3 from opposite sides. The linkage component includes:

[0049] Two crossbars 41 are connected to two clamps 4 respectively. Specifically, each crossbar 41 is fixedly connected to its corresponding clamp 4 or is integrally formed with it. The two crossbars 41 are slidably mounted on the pot lid body 2 along the opening and closing direction of the clamps 4. To make the sliding of the crossbars 41 more stable, the pot lid body 2 is provided with a guide groove 21 for the crossbars 41, and the two crossbars 41 are slidably mounted within the guide groove 21.

[0050] Two drive posts 42 are respectively connected between the two crossbars 41 and the knob 1. Specifically, the upper ends of the two drive posts 42 are inserted into the knob 1, and the lower ends of the two drive posts 42 are respectively inserted into the two crossbars 41. The pot lid body 2 is provided with arc-shaped guide holes 222 that cooperate with the two drive posts 42. Specifically, the knob 1 is provided with two drive post insertion parts, which can be holes or slots. The upper ends of the two drive posts 42 are respectively inserted into the two drive post insertion parts, and the lower ends of the two drive posts 42 are respectively inserted into the positioning holes on the two crossbars 41. When the knob 1 is rotated, the knob 1 drives the two clamps 4 to clamp or release the pot lid body 2 through the drive posts 42 and the crossbars 41. Specifically, when the knob 1 is turned in the forward direction, the knob 1 drives the two drive columns 42 to move toward each other, and the two drive columns 42 respectively drive the two crossbars 41 to move toward each other, thereby causing the two clamps 4 to clamp the pot lid body 2; when the knob 1 is turned in the reverse direction, the two clamps 4 release the pot lid body 2.

[0051] In some specific implementations, such as Figures 1 to 4As shown, the pot lid body 2 has a panel 22 located on the upper side of the two crossbars 41. The panel 22 is fixedly connected to the pot lid body 2. To reduce friction, an elastic gasket 224, which can be made of silicone, is provided between the panel 22 and each crossbar 41. Specifically, the lower side of the panel 22 has two connecting parts 223 for connecting to the pot lid body 2. Each elastic gasket 224 is located between its corresponding connecting part 223 and the crossbar 41. The connecting part 223 can be fixedly connected to the pot lid body 2 by screws. Each crossbar 41 has a clearance hole 411, and the two screws pass through the two clearance holes 411 respectively. Each elastic gasket 224 is sleeved on its corresponding screw and located between the connecting part 223 and the crossbar 41. Alternatively, a plug-in part can be provided at the lower end of the connecting part 223 to connect to the pot lid body 2, and the plug-in part passes through the clearance hole 411. The clearance hole 411 is used so that when the knob 1 is turned, the crossbar 41 slides relative to the screw through the clearance hole 411, thereby allowing it to slide smoothly on the pot lid body 2. The crossbar 41 may also be provided with a pressure valve mounting hole or an exhaust valve mounting hole, which may be configured to communicate with the corresponding clearance hole 411.

[0052] To facilitate the installation of the knob 1, the panel 22 is provided with a knob mounting groove 221. The knob 1 is rotatably mounted in the knob mounting groove 221, and both of the arc-shaped guide holes 222 are located on the bottom wall of the knob mounting groove 221. Specifically, the first mounting groove 225 extends upward from the bottom wall of the knob mounting groove 221.

[0053] In some specific implementations, such as Figure 3 , Figure 7 and Figure 8 As shown, the knob 1 includes a handwheel 11 and a rotating part 12 located below the handwheel 11. The handwheel 11 and the rotating part 12 are fixedly connected by screws. The handwheel 11 is provided with a first anti-fooling part, and the rotating part 12 is provided with a second anti-fooling part that cooperates with the first anti-fooling part. When assembling the knob 1, the anti-fooling structure ensures that the handwheel 11 and the rotating part 12 can only be assembled in a single correct relative position, thereby allowing the drive column 42 located between the knob 1 and the crossbar 41 to be accurately fitted and installed.

[0054] The plurality of protruding ribs 122 are located on the lower side of the rotating part 12. Specifically, the lower side of the rotating part 12 is provided with an upwardly recessed limiting groove, and the plurality of protruding ribs 122 are located on the top wall of the limiting groove.

[0055] The first anti-mistake part includes a plurality of protrusions 111 surrounding the handwheel 11, and the second anti-mistake part includes a plurality of anti-mistake grooves 121 surrounding the rotating part 12, with each of the protrusions 111 corresponding to one of the anti-mistake grooves 121. A preferred quantity is two protrusions 111 and two anti-mistake grooves 121, facilitating accurate assembly.

[0056] Working principle explanation:

[0057] When the knob 1 is turned, the knob 1 drives the two crossbars 41 to move away from or towards each other through the two drive columns 42, thereby causing the two clamps 4 to clamp or release the pot lid body 2. During the rotation of the knob 1, the abutment part 226 slides alternately over the protruding rib 122 and the recess between the two protruding ribs 122 under the reset action of the elastic element 227, thereby producing a feedback sound effect such as "tap, tap...", which enhances the user experience.

[0058] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
