Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a pot lid and a pot. Background Technology

[0002] Pressure cookers raise the boiling point of liquids inside, accelerating cooking and are commonly used in everyday cooking. Because pressure cookers increase boiling point by increasing pressure inside the pot, they require excellent sealing. Currently, the most common type of pressure cooker is the clamp-type, where clamps on the lid can move relative to the pot body to achieve a clamped or open state. However, switching between these clamped and open states is cumbersome, resulting in a poor user experience. Utility Model Content

[0003] This application provides a pot lid and pot that facilitates the switching of the clamping assembly between a clamping state and an open state, thereby improving the user experience.

[0004] The first aspect of this application provides a pot lid, the pot lid comprising: a lid body; a clamp assembly, the clamp assembly comprising a drive member and at least two clamps, the clamps being movably connected to the lid body, the drive member being capable of moving relative to the lid body along the height direction of the pot lid to drive the clamps to move closer to each other or further away from each other, so that the clamp assembly is in a clamped state or an open state.

[0005] The pot lid also includes a locking assembly movably connected to the drive member. In the open state, the locking assembly can restrict the drive member from moving relative to the lid body along the height direction of the pot lid, so as to restrict the clamp assembly to the open state.

[0006] In this design, the movement of the driving component relative to the lid along the height of the lid drives the clamps to move closer or further apart. This means the user only needs to press the driving component to open or close the clamp assembly, offering convenient operation. Furthermore, the vertical movement of the driving component is converted into radial reciprocating motion of the clamps, increasing the clamp's stroke within a smaller space and thus improving the reliability of the clamp's movement. Additionally, by incorporating a locking component, the user can keep the clamp assembly open without continuous operation of the driving component, further enhancing ease of operation and reducing the risk of accidental closure due to accidental activation of the driving component, thus improving the reliability and stability of the clamp assembly when it is open.

[0007] In one possible design, the locking assembly includes a locking member having an extension, and the driving member is provided with a first limiting portion. In the open state, the extension abuts against the first limiting portion along the height direction of the lid to restrict the movement of the driving member along the height direction of the lid.

[0008] In this solution, the extension on the locking member abuts against the first limiting part on the driving member, thereby locking the degree of freedom of the driving member to move along the height direction of the pot lid, so that the driving member is in the first position. In this first position, the clamping assembly is in the open state, thereby improving the stability of the clamping assembly in the open state. Moreover, the extension and the first limiting part form a rigid limiting structure by abutting against each other, which can effectively suppress the unexpected displacement of the driving member caused by gravity or vibration, prevent accidental contact with the driving member or vibration from causing the clamping assembly to switch from the open state to the clamping state, and improve the reliability of the clamping assembly during use.

[0009] In one possible design, the drive member has a groove extending along the height direction of the pot lid. During the movement of the drive member along the height direction of the pot lid, the extension can slide along the groove and move radially outward along the pot lid to abut against the first limiting portion, thereby restricting the clamp assembly to the open state.

[0010] In this design, the cooperation between the sliding groove and the extension provides a directional sliding path for the locking component, ensuring that the extension maintains a preset movement trajectory as the driving component moves along the height direction of the lid, thus avoiding jamming caused by the tilting of the locking component and the driving component. Furthermore, when the clamp assembly opens to a predetermined angle, the extension moves radially outward and abuts against the first limiting part along the height direction of the lid, restricting the movement of the driving component along the height direction. Therefore, in this embodiment, the cooperation between the sliding groove and the first limiting part of the locking component and the driving component improves the stability of the driving component's movement along the height direction and also locks the driving component, improving the continuity of the clamp assembly's opening and closing action and its stability when maintaining the open state.

[0011] In one possible design, the first limiting portion extends from the side wall of the slide into the interior of the slide, and the first limiting portion and the bottom wall of the slide have a first gap along the radial direction of the lid, and the extension portion is capable of moving within the gap;

[0012] The first limiting part and the top wall of the driving member have a second gap along the height direction of the pot lid, so that the extension part can move radially along the pot lid through the second gap.

[0013] In this solution, by setting a first gap between the first limiting part and the bottom wall of the slide, the extension of the locking member can move along the first gap. That is, the first gap can guide the first limiting part. The first limiting part extends from the side wall of the slide into the interior of the slide, and the extension is close to the first limiting part. This can increase the contact area between the extension and the first limiting part along the radial direction of the pot lid, making the relative movement of the first limiting part and the extension part along the height direction of the pot lid more stable, thereby improving the stability of the driving member moving along the height direction.

[0014] A second gap is provided between the first limiting part and the top wall of the driving member. When the extension of the locking member moves along the height direction to the second gap, the first limiting part no longer obstructs the radial movement of the extension along the lid, allowing the extension to move radially outward along the lid, so that the extension abuts against the first limiting part in the height direction. Therefore, the second gap ensures that when the driving member moves to the preset position, it is in a position where the locking member restricts the driving member from continuing to move along the height direction, keeping the clamp assembly in the open state and improving the reliability and stability of the clamp assembly in the open state.

[0015] In one possible design, the locking assembly further includes a first elastic member and an abutment member. The first elastic member is connected to the locking member and the abutment member at both ends along the radial direction of the lid. During the movement of the driving member along the height direction of the lid, the abutment member abuts against the driving member, and the first elastic member is in a compressed state. When the driving member moves to a preset position along the height direction of the lid, under the action of the rebound force of the first elastic member, the extension can move along the radial direction of the lid to abut against the first limiting part.

[0016] In this design, by placing the second elastic element between the abutment and the locking element, the first elastic element is compressed when the driving element moves along the height of the lid. The rebound force of the first elastic element provides tactile feedback for the driving element's movement along the height direction, improving the user's experience of pressing the driving element. When the extension of the locking element aligns with the second gap, the rebound force of the first elastic element drives the locking element to move radially along the lid, i.e., pushing the extension to move radially outward along the lid. This means the extension moves through the second gap to abut against the first limiting element, positioning the locking assembly to lock the driving element. Therefore, the first elastic element allows the locking element to automatically lock in the driving element position, achieving locking without additional operation and simplifying the process.

[0017] In one possible design, the clamp assembly further includes at least two moving parts, the drive part having a drive portion, one end of the moving part being connected to the clamp, and the other end of the moving part cooperating with the drive part, wherein during the pressing of the drive part, the drive portion can push at least two of the moving parts to move at least two of the clamps away from each other.

[0018] In this solution, one end of the moving part is connected to the clamp, and the other end abuts against the drive unit. During the pressing process of the drive part, the movement of the drive part along the height direction of the pot lid is converted into the radial movement of the clamp along the pot lid by the moving part. That is, the user only needs to press the drive part to make the two moving parts drive the clamp away from each other, so that the clamp assembly is in the open state, which is simple and convenient to operate.

[0019] In one possible design, the cross-section of the drive unit is tapered.

[0020] In this design, the pressing action of the drive component is converted into the radial movement of the moving component along the lid via the conical inclined surface of the drive unit. That is, the drive component can efficiently convert the axial pressing force into the radial driving force of the moving component, which can ensure the stable opening of the moving component while saving effort. The slope of the conical section is fixed, and the speed of the moving component is stable and controllable when it moves radially along the conical inclined surface. This ensures that the clamp assembly can open at a uniform speed during the opening process, avoids rigid impact caused by sudden speed changes, and ensures the stability of the clamp assembly during the opening and closing process.

[0021] In one possible design, a rolling part is rotatably connected to one end of the moving part that cooperates with the driving part, and the driving part cooperates with the rolling part to drive the rolling part to rotate.

[0022] In this solution, the design of the rolling part enables rolling friction between the driving component and the moving component, reducing the frictional force that the driving component needs to overcome when driving the moving component. This allows the force applied to the driving component to be efficiently transmitted to the moving component. Furthermore, the inclined surfaces of the rolling part and the driving part generate a continuously changing contact trajectory during rolling contact, which ensures the smooth transmission of driving force. This ensures that the driving component can drive the moving component more easily and stably, improving the convenience and reliability of the pot lid during use.

[0023] In one possible design, the clamp assembly further includes a second elastic element, the two ends of which are respectively connected to two moving elements arranged opposite to each other along the movement direction of the clamp.

[0024] In this design, the second elastic element is positioned between two opposing moving parts, with both ends connected to the two moving parts respectively. When the clamp assembly is in the open state, the two moving parts move away from each other, causing the second elastic element to be stretched. At this time, the driving part is limited by the locking part, keeping the clamp assembly in the open state. When the locking part releases its limiting effect on the driving part, the rebound force of the second elastic element drives the two moving parts to move the two clamps closer together, thus automatically restoring the clamp assembly to the clamping state. This means that the clamp assembly can return to the clamping state without user intervention, simplifying the operation. Furthermore, since the clamp assembly needs to overcome the elastic force of the second elastic element to open, the stability and reliability of the clamp assembly's operation are improved.

[0025] In one possible design, the clamp assembly further includes a cover plate and at least two fasteners, the cover plate being connected to the fasteners by fasteners and clamping the moving element between the cover plate and the fasteners, the cover plate being mounted on the cover body;

[0026] The moving part has a clearance hole for avoiding the fastener.

[0027] In this design, the fixing component and the cover plate are fixedly connected by fasteners, and the moving component is clamped between the fixing component and the cover plate. This connects the clamp, moving component, cover plate, and fixing component into a clamp assembly, which can be installed as a whole onto the lid body. During installation, the cover plate and lid body can be connected using fasteners. Installing the clamp assembly as a whole onto the lid body offers the advantage of convenient installation and reduces the decrease in installation accuracy caused by the accumulation of tolerances when individual components are installed on the lid body.

[0028] In one possible design, the lid further includes a third elastic element, one end of which is connected to the drive element and the other end of which is connected to the lid body along the height direction of the lid.

[0029] In this design, when the driving component is not pressed, the third elastic element supports the driving component in its current position, and the clamping assembly is in a clamping state when the driving component is in this position. When the user presses the driving component, the driving component and the cover compress the third elastic element. During this process, the locking element slides along the groove of the driving component. When the driving component is pressed until the extension of the locking element aligns with the second gap, under the rebound force of the first elastic element, the locking element moves radially outward until the extension abuts against the first limiting part. At this time, the locking element restricts the driving component from being pressed further, keeping the clamping assembly in the open state, and the third elastic element is in a compressed state. When the user presses the locking member radially, disengaging the extension of the locking member from the first limiting part, the rebound force of the third elastic member pushes the driving member upward along the height direction of the lid, causing the driving member to self-reset. This means the driving member can return to the position where the clamping assembly is in the clamping state under the rebound force of the third elastic member. The design of the third elastic member enables the driving member to have a self-resetting function, improving operational convenience. Furthermore, if the user accidentally touches the driving member while the clamping assembly is in the clamping state, the rebound force of the third elastic member will automatically return the driving member to the clamping position, preventing the clamping assembly from being in a semi-clamped state and improving the reliability and stability of the clamping assembly in the clamping state.

[0030] In one possible design, the pot lid further includes a base fixed to the lid body. The base and the driving member are provided with a locking part and a locking groove, respectively. During the process of the third elastic member driving the driving member to move upward along the height direction of the pot lid, the locking groove and the locking part can be locked to prevent the driving member from detaching from the base.

[0031] In this design, the pot lid also includes a base, which is fixed to the lid body. The driving component can move relative to the base along the height direction of the pot lid. One of the base and the driving component has a locking part, and the other has a locking groove. When the third elastic member drives the driving component to move upward along the height direction of the pot lid, the locking groove can engage with the locking part. This description uses an example where the base has a locking groove and the driving component has a locking part. In other embodiments, the base may also have a locking part, and the driving component may also have a locking groove.

[0032] A second aspect of this application provides a cookware, the cookware including a pot body and a pot lid, the pot lid being closed onto the opening of the pot body, the pot lid being the pot lid described above; when the clamping assembly is in a clamping state, the clamping clamps the lid body and the pot body, and when the clamping assembly is in an open state, the clamping clamp releases the clamping action on the lid body and the pot body.

[0086] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0087] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0088] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0089] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0090] This application provides a cookware, which includes a pot body and a lid, the lid of which can be closed onto the opening of the pot body. The lid has clamps that can clamp the lid and the pot body tightly when the lid is attached to the pot body.

[0091] In some embodiments, the specific type of cookware may be a rice cooker, a multi-functional cooker, a pressure cooker, etc., but this application does not limit the specific type of cookware. The following description uses a pressure cooker as an example.

[0092] like Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a pot lid, which includes a lid body 1 and a clamping assembly 2. The lid body 1 is used to cover the opening of the pot body. The lid body 1 is provided with a sealing ring, a pressure limiting valve 7 and a check valve. The sealing ring can form a sealing state with the pot body. The pressure limiting valve 7 is used to limit the maximum pressure inside the pot. The check valve is inserted through the clamping assembly 2 and can rise or fall along the height direction of the lid body 1. When the check valve rises, the pot lid forms a sealed state, and high pressure can be formed inside the pot, and the pot lid cannot be opened. When the check valve falls, a pressure relief state is formed, the pressure inside the pot is released, and the pot lid can be opened normally.

[0093] The clamp assembly 2 includes at least two clamps 22, which are movably connected to the lid 1. The at least two clamps 22 can slide radially along the lid 1, so that the clamp assembly 2 is in a clamping state or an open state. When the at least two clamps 22 are close to each other, the clamp assembly 2 is in a clamping state, that is, the clamps 22 simultaneously clamp the pot body and the pot lid. When the at least two clamps 22 are far apart from each other, the clamp assembly 2 is in an open state, that is, the pot lid and the pot body can be separated from each other.

[0094] The pot lid provided in this embodiment also includes a driving member 21, which can move along the height direction of the lid body 1 to drive the clamps 22 to move closer or further apart to achieve clamping or opening.

[0095] The pot lid also includes a locking component 3 that is movably connected to the drive component 21. When the clamping component 2 is in the open state, the locking component 3 can restrict the drive component 21 from moving in the height direction relative to the lid body 1, so that the clamping component 2 is restricted to the open state.

[0096] In this embodiment, the movement of the driving member 21 relative to the lid 1 along the height direction of the lid drives the clamps 22 to move closer or further apart. This means the user only needs to press the driving member 21 to open or close the clamp assembly 2, offering the advantage of convenient operation. Furthermore, the height-direction movement of the driving member 21 is converted into radial reciprocating motion of the clamps 22, increasing the stroke of the clamps 22 within a smaller space and thus improving the reliability of the clamp movement. Additionally, by providing the locking component 3, the user can keep the clamp assembly 22 in the open state without continuously operating the driving member 21, further simplifying operation and reducing the risk of accidental closure of the clamp assembly 22 due to accidental activation of the driving member 21, thus improving the reliability and stability of the clamp assembly 2 when it is in the open state.

[0097] The specific structure of the driving component 21 can be a button structure, which enables the driving component 21 to move along the height direction of the pot lid.

[0098] In some embodiments, such as Figure 3 As shown, the locking assembly 3 includes a locking member 31, which has an extension 311, such as... Figure 4 As shown, the driving component 21 is provided with a first limiting part 211, which, when the clamp assembly 2 is in the open state, such as Figure 5 As shown, the extension 311 abuts against the first limiting part 211 along the height direction of the pot lid to restrict the movement of the driving member 21 along the height direction of the pot lid.

[0099] In this embodiment, the extension 311 on the locking member 31 abuts against the first limiting part 211 on the driving member 21, thereby locking the degree of freedom of the driving member 21 to move along the height direction of the pot lid, so that the driving member 21 is in the first position. In this first position, the clamping assembly 2 is in the open state, thereby improving the stability of the clamping assembly 2 in the open state. Moreover, the extension 311 and the first limiting part 211 form a rigid limiting structure by abutting against each other, which can effectively suppress the unexpected displacement of the driving member 21 caused by gravity or vibration, prevent accidental contact with the driving member 21 or vibration causing the clamping assembly 2 to switch from the open state to the clamping state, and improve the reliability of the clamping assembly 2 during use.

[0100] In some embodiments, such as Figures 3-7As shown, the drive member 21 also has a slide groove 212 extending along the height direction of the pot lid. Along the radial direction of the pot lid, the first limiting part 211 is located outside the slide groove 212. During the movement of the drive member 21 along the height direction of the pot lid, the extension part 311 is located inside the slide groove 212 and can slide along the slide groove 212. The extension part 311 can move radially to abut against the first limiting part 211, thus restricting the clamp assembly 2 to the open state.

[0101] In this embodiment, the sliding groove 212 and the extension 311 cooperate to provide a directional sliding path for the locking member 31, ensuring that the extension 311 maintains a preset movement trajectory during the movement of the driving member 21 along the height direction of the pot lid, avoiding jamming caused by the tilting of the locking member 31 and the driving member 21. Furthermore, when the clamp assembly 22 opens to a predetermined angle, the extension 311 moves radially outward and abuts against the first limiting part 211 along the height direction of the pot lid, restricting the movement of the driving member 21 along the height direction. Therefore, in this embodiment, the cooperation between the locking member 31 and the sliding groove 212 and the first limiting part 211 of the driving member 21 can improve the stability of the driving member 21's movement along the height direction and also achieve locking of the driving member 21, improving the continuity of the opening and closing action of the clamp assembly 2 and the stability when maintaining the open state.

[0102] The cross-section of the groove 212 can be rectangular. In other embodiments, the cross-section of the groove 212 can also be circular, triangular, etc. This application does not limit the cross-sectional shape of the groove 212.

[0103] In some embodiments, such as Figures 4-9 As shown, the first limiting part 211 extends from the side wall of the slide 212 into the interior of the slide 212, and the first limiting part 211 and the bottom wall of the slide 212 have a first gap 9, which is the gap between the first limiting part 211 and the bottom wall of the slide 212 along the radial direction of the lid. A second gap 4 is formed between the first limiting part 211 and the top wall of the driving member 21, which is the gap between the first limiting part 211 and the top wall of the driving member 21 along the height direction of the lid. This second gap 4 allows the extension part 311 to move radially along the lid at the second gap 4.

[0104] In this embodiment, reference Figures 4-9By setting a first gap 9 between the first limiting part 211 and the bottom wall of the slide 212, the extension part 311 of the locking member 31 can move along the first gap 9. That is, the first gap 9 can guide the first limiting part 211. The first limiting part 211 extends from the side wall of the slide 212 into the interior of the slide 212. The extension part 311 is close to the first limiting part 211, which can increase the contact area between the extension part 311 and the first limiting part 211 along the radial direction of the pot lid. This makes the relative movement of the first limiting part 211 and the extension part 311 along the height direction of the pot lid more stable, thereby improving the stability of the drive member 21 moving along the height direction.

[0105] A second gap 4 is provided between the first limiting part 211 and the top wall of the driving member 21. When the extension part 311 of the locking member 31 moves to a preset position in the height direction (the extension part is aligned with the second gap), the first limiting part 211 no longer obstructs the radial movement of the extension part 311 along the lid, allowing the extension part 311 to move radially outward along the lid, so that the extension part 311 abuts against the first limiting part 211 in the height direction. Therefore, the setting of the second gap 4 ensures that when the driving member 21 moves to the preset position, it is in a position where the locking member 31 restricts the driving member 21 from continuing to move in the height direction, keeping the clamp assembly 2 in the open state and improving the reliability and stability of the clamp assembly 2 in the open state.

[0106] In some embodiments, such as Figure 8 , Figure 9 As shown, the locking assembly 3 may further include a first elastic member 32 and an abutment member 33. The two ends of the first elastic member 32 along the radial direction of the pot lid are respectively connected to the locking member 31 and the abutment member 33. During the movement of the driving member 21 along the height direction of the pot lid, the abutment member 33 abuts against the driving member 21. Specifically, the abutment member 33 abuts against the bottom wall of the sliding groove 212 of the driving member 21. During the movement of the driving member 21 along the height direction of the pot lid, the first elastic member 32 is in a compressed state, and under the action of the rebound force of the first elastic member 32, the extension 311 can move radially along the pot lid to abut against the first limiting part 211.

[0107] In this embodiment, by placing the second elastic element 24 between the abutment element 33 and the locking element 31, when the driving element 21 moves along the height direction of the lid, the first elastic element 32 is in a compressed state. The rebound force of the first elastic element 32 provides a tactile feel for the movement of the driving element 21 along the height direction, improving the user's experience of pressing the driving element 21. When the extension 311 of the locking element 31 aligns with the second gap 4, the rebound force of the first elastic element 32 drives the locking element 31 to move radially along the lid, that is, pushes the extension 311 to move radially outward along the lid, that is, the extension 311 moves through the second gap 4 to abut against the first limiting part 211, so that the locking assembly 3 is in the position of locking the driving element 21. Therefore, the setting of the first elastic element 32 enables the locking element 31 to automatically be in the position of locking the driving element 21, achieving locking without additional operation and simplifying the operation steps.

[0108] refer to Figures 10-12 When the clamp assembly 2 is in a clamping state, or when the drive member 21 moves along the height direction and the extension 311 is not aligned with the second gap 4, the first elastic member 32 is in a compressed state under the action of the abutment member 33 and the locking member 31.

[0109] refer to Figure 13 , Figure 14 When the extension 311 of the locking member 31 is aligned with the second gap 4, the abutting action of the locking member 31 is released. Under the action of the rebound force of the first elastic member 32, the locking member 31 is driven to move radially outward, so that the extension 311 abuts with the first limiting part 211 to restrict the driving member 21 from being pressed in the height direction. At this time, the clamp assembly 2 is in the open state.

[0110] In some embodiments, such as Figure 8 and Figure 9 As shown, the end face of the abutment 33 that contacts the driving member 21 is an arc surface, thereby reducing wear during the relative movement of the abutment 33 and the driving member 21.

[0111] In some embodiments, such as Figure 15 As shown, the pot lid also includes a third elastic member 5, one end of which is connected to the driving member 21 and the other end is connected to the lid body 1.

[0112] In this embodiment, when the driving member 21 is not pressed, the third elastic member 5 supports the driving member 21 in its current position, and the clamping assembly 2 is in a clamping state when the driving member 21 is in this position. When the user presses the driving member 21, the driving member 21 and the cover 1 compress the third elastic member 5. During this process, the locking member 31 slides along the slide groove 212 of the driving member 21. When the driving member 21 is pressed until the extension 311 of the locking member 31 aligns with the second gap 4, under the action of the rebound force of the first elastic member 32, the locking member 31 moves radially outward until the extension 311 abuts against the first limiting part 211. At this time, the locking member 31 restricts the driving member 21 from being pressed further, keeps the clamping assembly in the open state, and the third elastic member 5 is in a compressed state. When the user presses the locking member 31 radially, causing the extension 311 of the locking member 31 to disengage from the first limiting part 211, the driving member 21 is pushed upward along the height direction of the lid by the rebound force of the third elastic member 5, causing the driving member 21 to self-reset. That is, the driving member 21 can be returned to the position where the clamping assembly 2 is in the clamping state by the rebound force of the third elastic member 5. The design of the third elastic member 5 enables the driving member 21 to have a self-resetting function, improving the convenience of operation. Furthermore, when the clamping assembly 22 is in the clamping state and the user accidentally touches the driving member 21, the driving member 21 can automatically return to the position where the clamping assembly 2 is in the clamping state by the rebound force of the third elastic member 5, thereby preventing the clamping assembly 2 from being in a semi-clamped state and improving the reliability and stability of the clamping assembly in the clamping state.

[0113] In some embodiments, such as Figure 15-17 As shown, the pot lid also includes a base 6, which is fixed to the lid body 1. The driving member 21 can move relative to the base 6 along the height direction of the pot lid. One of the base 6 and the driving member 21 is provided with a locking part 214, and the other with a locking groove 61. When the third elastic member 5 drives the driving member 21 to move upward along the height direction of the pot lid, the locking groove 61 can engage with the locking part 214. This description uses the example of the base 6 having a locking groove 61 and the driving member 21 having a locking part 214. In other embodiments, the base 6 may also have a locking part 214, and the driving member 21 may also have a locking groove 61.

[0114] In this embodiment, as Figure 13 , Figure 16 and Figure 17 As shown, the base 6 is fixed to the lid 1, that is, the position of the base 6 relative to the lid 1 is fixed. The base 6 is provided with a slot 61, and the driving member 21 is provided with a locking part 214. During the process of the third elastic member 5 pushing the driving member 21 to move upward, the locking part 214 locks with the slot 61 to restrict the driving member 21 from continuing to move upward, and prevent the driving member 21 from detaching from the lid under the elastic force of the third elastic member 5.

[0115] Specifically, the base 6 also includes a through hole 62, through which the locking member 31 passes. The through hole 62 can provide guidance for the radial movement of the locking member 31, ensuring the stability of the radial movement of the locking member 31.

[0116] In the above embodiments, as Figure 4 , Figure 11 , Figure 13 and Figure 18 As shown, the clamp assembly 2 also includes at least two moving parts 23, one end of which is connected to the clamp 22. The driving part 21 has a driving part 213. When the driving part 21 is pressed, the driving part 213 can push the at least two moving parts 23 to drive the at least two clamps 22 away from each other.

[0117] In this embodiment, one end of the moving part 23 is connected to the clamp 22, and the other end abuts against the drive part 213. During the pressing process of the drive part 21, the movement of the drive part 21 along the height direction of the pot lid is converted into the movement of the clamp 22 along the radial direction of the pot lid by the moving part 23. That is, the user only needs to press the drive part 21 to make the two moving parts 23 drive the clamp 22 away from each other, so that the clamp assembly 2 is in the open state, which is simple and convenient to operate.

[0118] Specifically, such as Figure 4 As shown, the drive unit 213 has a tapered cross-section. The cross-section of the drive unit 213 can be a plane parallel to the height direction of the lid.

[0119] In this embodiment, the pressing action of the driving member 21 is converted into the radial movement of the moving member 23 along the lid by the conical inclined surface of the driving part 213. That is, the driving member 21 can efficiently convert the axial pressing force into the radial driving force of the moving member 23, which can ensure the stable opening of the moving member 23 while saving effort. The slope of the conical section is fixed, and the speed of the moving member 23 is stable and controllable when it moves radially along the conical inclined surface. This ensures that the clamp 22 assembly can open at a uniform speed during the opening process, avoids rigid impact caused by sudden speed changes, and ensures the stability of the clamp assembly 2 during the opening and closing process.

[0120] In some embodiments, the inclined surfaces of the drive unit 213 that contact the moving member 23 have the same inclination angle, that is, the inclined surfaces are symmetrical with respect to the height direction of the pot lid. The symmetrical design of the conical inclined surface enables the moving member 23 to achieve synchronous separation along a preset trajectory.

[0121] In some embodiments, Figure 18As shown, the moving part 23 includes a main body 232, a first connecting part 233, and a second connecting part 234. Along the radial direction of the lid, the first connecting part 233 and the second connecting part 234 are respectively connected to both sides of the main body 232. The other end of the first connecting part 233 is connected to the clamp 22, and the second connecting part 234 abuts against the driving part 21. The first connecting part 233 is inclined downwards relative to the main body 232.

[0122] In this embodiment, the first connecting part 233 is inclined downward relative to the main body part 232. The first connecting part 233 can transmit force to planes of different heights. The first connecting part 233 is connected to the clamp 22, which allows the moving part 23 to drive the clamp 22 of different height planes connected to the first connecting part 233 to move. The clamp assembly 2 is set at a position that decreases along the height direction of the pot lid, which can ensure that there is enough space inside the pot lid to set the moving part 23, pressure relief valve 7, check valve, etc., reduce the interference of each component on the movement of the clamp 22, and improve the stability and reliability of the clamp 22 when opening and closing.

[0123] Specifically, the main body 232, the first connecting part 233 and the second connecting part 234 are integrally formed. The integrated design can reduce the reduction in installation accuracy caused by the accumulation of tolerances when connecting multiple parts and improve the installation accuracy of the moving part 23.

[0124] Specifically, such as Figure 18 , Figure 19 As shown, the end of the moving part 23 that cooperates with the driving part 21 has a rolling part 231. The rolling part 231 can rotate relative to the moving part 23. The driving part 213 abuts against the rolling part 231, that is, the driving part 213 can drive the rolling part 231 to roll and rotate.

[0125] In this embodiment, the design of the rolling part 231 enables rolling friction between the driving member 21 and the moving member 23, reducing the frictional force that the driving member 21 needs to overcome when driving the moving member 23. This allows the force applied to the driving member 21 to be efficiently transmitted to the moving member 23. Furthermore, the inclined surfaces of the rolling part 231 and the driving part 213 generate a continuously changing contact trajectory during rolling contact, ensuring the smooth transmission of driving force. This ensures that the driving member 21 can drive the moving member 23 more easily and stably, improving the convenience and reliability of the pot lid during use.

[0126] In some embodiments, such as Figure 18 , Figure 19 As shown, the clamp assembly 2 includes at least two second elastic members 24, the two ends of which are connected to two opposing moving members 23.

[0127] In this embodiment, the second elastic element 24 is disposed between two opposing moving elements 23 and connected to both ends of the two moving elements 23 respectively. When the clamp assembly 2 is in the open state, the two moving elements 23 move away from each other, causing the second elastic element 24 to be stretched. At this time, the driving element 21 is limited by the locking element 31, keeping the clamp assembly 2 in the open state. When the limiting effect of the locking element 31 on the driving element 21 is released, under the action of the rebound force of the second elastic element 24, the two moving elements 23 are driven to move the two clamps 22 closer to each other, thereby automatically restoring the clamp assembly 2 to the clamping state. That is, the clamp assembly 2 can be returned to the clamping state without user operation, simplifying the operation steps. Moreover, since the clamp assembly 2 needs to overcome the elastic force of the second elastic element 24 to open, the stability and reliability of the clamp assembly 2 are improved.

[0128] Therefore, in the embodiments of this application, the functions of the three elastic elements are as follows: when the user presses the driving member 21 down to the preset position (the extension 311 is aligned with the second gap 4), the first elastic element 32 automatically puts the locking member 31 in the position that restricts the driving member 21 from being pressed, thereby restricting the clamp assembly 2 to the open state. When the user presses the locking member 31 to release the limiting effect of the locking member 31 on the driving member 21, the limiting effect of the driving member 21 on the moving member 23 and the clamp 22 is released, and the second elastic element 24 automatically makes the moving member 23 and the clamp 22 move radially along the lid, thereby putting the clamp assembly 2 in the clamping state. During this process, the third elastic element 5 can drive the driving member 21 to move upward to the initial position (the initial position is the position where the clamp assembly 2 is in the clamping state).

[0129] Therefore, in this embodiment, by setting the above three elastic elements, the operation of the clamp assembly 2, the driving member 21 and the locking assembly 3 is convenient, and the clamp assembly 2, the driving member 21 and the locking assembly 3 are linked to realize the clamping state and the opening state of the clamp assembly 2, and the stability of the clamp assembly 2 in both the clamping state and the opening state is high, preventing the clamp assembly 2 from being in a half-open or half-clamping state.

[0130] In the above embodiments, such as Figure 20 As shown, the cover plate 26 also includes a second limiting part 261, and the fixing member 25 can be installed in the second limiting part 261. The second limiting part 261 improves the connection stability between the moving member 23 and the cover plate 26 and the fixing member 25.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
