Description

Technical Field

[0001] The present invention relates to a stewing pot, and particularly to an anti-overflow pot lid, a pot lid assembly and a stewing pot. Background Art

[0002] As a traditional stewing cooking utensil, the casserole has gradually become a widely used cooking utensil in families and the catering industry due to its excellent heat storage performance, uniform heat distribution, mellow flavor of stewed ingredients, and no metal precipitation. However, there are significant defects in the anti-overflow design of existing casseroles, which seriously affect the user experience and safety, and are specifically manifested as the following problems:

[0003] "Explosive boiling" causes soup overflow and safety hazards. The casserole heats up slowly and the pot lid is heavy. During continuous heating, it is easy to cause violent boiling (i.e., "explosive boiling") due to a sudden increase in internal pressure. At this time, a large amount of soup or steam is ejected rapidly through the air holes in the pot lid, which will not only contaminate the kitchen countertop, but also may extinguish the open flame of the stove, leading to safety hazards such as gas leakage.

[0004] The performance of the traditional air hole design is insufficient. The air holes in the existing casserole pot lids are of a fixed open structure and cannot dynamically adjust the exhaust volume according to the internal pressure of the pot. When boiling, the steam directly discharged from the air holes carries liquid droplets, which is easy to form a long-distance jet (up to more than 1 meter), greatly increasing the cleaning difficulty. In addition, the overflowing soup flows down the outer wall of the pot to the stove top, further increasing the cleaning burden.

[0005] Inconvenience and risks brought about by user operation compromises. To avoid soup overflow, users are often forced to adopt abnormal operation methods such as "simmering with the lid open" or "misaligned lid closing". The former significantly prolongs the cooking time and reduces the thermal efficiency; the latter is prone to the risk of secondary soup overflow because the pot lid is easily pushed back to its original position by the steam, and it is difficult to fundamentally solve the problem.

[0006] Currently, commercially available casseroles generally do not have a reliable anti-overflow device, and users have an urgent need for an anti-overflow casserole that combines safety, convenience and efficiency. The defects of the existing technology have become the key factors restricting the further popularization of casseroles. Based on the above problems, there is an urgent need for an anti-overflow pot lid and stewing pot solution that can improve the safety and convenience of using casseroles and meet the market demand. Summary of the Invention

[0007] In order to solve the deficiencies of the above-mentioned technologies, the present invention provides an anti-overflow pot lid, a pot lid assembly and a stewing pot.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: an anti-overflow pot lid, including a pot lid body, and a steam and soup outlet is vertically penetrated through the center of the pot lid body to discharge the steam or the flowing soup inside the pot body to the outside.

[0009] An anti-overflow pot lid assembly includes an anti-overflow pot lid. The steam and liquid outlet is an automatically openable and closable steam and liquid outlet, and the automatically openable and closable steam and liquid outlet is formed by covering a baffle that moves upward after being lifted by steam or liquid on the steam and liquid outlet.

[0010] Further, the baffle includes a non-connected baffle or a connected baffle; the non-connected baffle is detachably arranged at the steam and liquid outlet to close or open the steam and liquid outlet; the connected baffle is connected to the pot lid body through a connecting body and is arranged at the steam and liquid outlet to cover or open the steam and liquid outlet.

[0011] An anti-overflow pot lid assembly includes an anti-overflow pot lid. A surrounding body is detachably arranged upward at the position of the steam and liquid outlet, and the surrounding body has a surrounding body passage communicating the inner and outer spaces of the pot body separated by the steam and liquid outlet.

[0012] Further, the surrounding body passage has an upper port and a lower port. The upper port is located above the steam and liquid outlet, the lower port coincides with the edge of the steam and liquid outlet, or the lower port surrounds the periphery of the vertical projection space of the steam and liquid outlet, or the lower port surrounds the inside of the vertical projection space of the steam and liquid outlet.

[0013] Further, it further includes a baffle. The baffle includes a non-connected baffle or a connected baffle; the non-connected baffle is detachably arranged on the surrounding body passage to close or open the communication between the inner and outer spaces of the pot body; the connected baffle is connected to the surrounding body passage through a connecting body and is arranged on the surrounding body passage to close or open the communication between the inner and outer spaces of the pot body.

[0014] Further, when the lower port coincides with the edge of the steam and liquid outlet, a receiving space for the liquid flowing out of the steam and liquid outlet is formed inside the surrounding body.

[0015] Further, when the lower port surrounds the periphery of the vertical projection space of the steam and liquid outlet, the receiving space of the baffle gradually expands from the lower port to the upper port.

[0016] Further, when the lower port surrounds the inside of the vertical projection space of the steam and liquid outlet, the receiving space of the baffle gradually expands from the lower port to the upper port, and the lower port is located below the steam and liquid outlet.

[0017] A stewing pot includes a pot body. The stewing pot includes an anti-overflow pot lid assembly, and the pot lid body is covered on the pot body.

[0018] The present invention discloses an anti-overflow pot lid, a pot lid assembly and a stewing pot. Through innovative design, the present invention effectively solves problems such as soup overflow, steam jet and safety hazards during traditional casserole stewing. Its core advantages are reflected in the collaborative work of the central steam-water port and the automatic opening and closing baffle. When the pressure in the pot rises, it automatically relieves pressure to prevent "explosive boiling" from causing violent boiling and reduce the risk of gas leakage; the gradually expanding or annular enclosure structure guides the overflowing soup to flow back into the pot under the action of gravity, significantly reducing the contamination of the tabletop and the cleaning burden; the adaptive pressure regulation design supports fully enclosed cooking, avoiding manual intervention by users, while improving the thermal efficiency, shortening the cooking time and reducing heat energy waste; providing diverse structures such as non-connected baffles, connected baffles and graded buffer enclosures, flexibly adapting to different scenario requirements such as porridge cooking, water boiling, soup stewing, etc.; through physical structure innovation, the present invention realizes the collaborative optimization of pressure regulation, liquid reflux and heat energy utilization, combining safety, convenience and energy conservation, applicable to family and catering scenarios, and having significant market value and social benefits.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] Embodiment 1;

[0033] As Figure 1 shown, an anti-overflow lid includes a lid body 1. A steam and soup outlet 2 is vertically penetrated through the center position of the lid body 1 for discharging steam inside the pot or flowing out soup. The diameter range of the steam and soup outlet is 1.5 cm, and the size of the steam and soup outlet is not limited to the above size. Through the centralized layout at the center position, the steam and soup outlet forms a vertically penetrated structure and is discharged by using the natural power of the rising steam. At the same time, the steam and soup outlet has the dual functions of discharging steam and soup. When the pressure inside the pot rises, steam is preferentially released to reduce the risk of violent boiling. Part of the soup that is about to overflow can naturally fall back into the pot under the action of gravity along the vertical passage, avoiding accumulation and overflow. Part of the soup flows back into the pot through the lid surface after flowing out of the steam and soup outlet, preventing the soup from overflowing. In addition, the steam and soup outlet is located at the center position to form a central symmetry design, which helps to balance the pressure distribution inside the pot, thus significantly improving the anti-overflow effect. In other embodiments, the position of the steam and soup outlet 2 includes that the steam and soup outlet can be arranged at a position deviating from the center of the lid or on the inclined surface of the lid, and still can preferentially release steam to reduce the risk of violent boiling when the pressure inside the pot rises, or part of the soup flows back into the pot through the lid surface after flowing out of the steam and soup outlet, preventing the soup from overflowing, and also has the effect of preventing the soup from overflowing.

[0034] Embodiment 2;

[0035] As Figure 2An anti-overflow pot lid assembly shown includes the anti-overflow pot lid disclosed in Embodiment 1. The steam and liquid outlet is an automatically openable and closable steam and liquid outlet 2. The automatically openable and closable steam and liquid outlet is formed by covering a baffle 3 that moves upward after being lifted by steam or juice on the steam and liquid outlet. In this embodiment, the diameter of the steam and liquid outlet 2 at the center of the pot lid of the pot lid body 1 is four centimeters, and the baffle 3 is a hemisphere with a diameter of 4.5 centimeters. The hemisphere is used as a non-connected baffle. In other embodiments, the hemisphere can be replaced by a sphere, and of course, it also includes baffles of other shapes, such as a conical baffle, but the diameter should be greater than the diameter of the steam and liquid outlet 2. When the baffle is a sphere, in order to prevent thermal expansion, holes can be provided in the sphere, and the lower part of the sphere is placed inside the steam and liquid outlet; in the specific implementation, add three liters of water to a four-liter casserole and heat it with an open fire on a gas stove at high heat. After heating for twenty minutes, the water boils, and the steam lifts the sphere upward, and the baffle opens to release gas outward. When the sphere moves to the maximum position, it moves downward, and then the sphere repeatedly moves up and down to release gas. When the fire is turned off, the water in the casserole stops boiling, and the sphere falls back above the steam outlet. The pot lid handle is provided separately. The soup flowing out of the steam and liquid outlet stays at the lower end of the pot lid. Add three liters of water and 200 grams of rice to a four-liter casserole to cook porridge, and heat it with an open fire on a gas stove at high heat. After heating for twenty minutes, the water boils, and the steam lifts the sphere upward, and the baffle opens to release gas outward and let the soup flow out. When the sphere moves to the maximum position, it moves downward, and then the sphere is lifted or repeatedly moves up and down. After heating with low heat, the sphere repeatedly moves up and down to release gas and let the soup flow out to the lower end of the pot lid and into the pot body. When the fire is turned off, the water in the casserole stops boiling, and the sphere falls back above the steam and liquid outlet; it should be noted that the pressure inside the casserole can be controlled and adjusted by setting the weight of the baffle.

[0036] The core advantage of this anti-overflow pot lid assembly lies in the synergistic effect of its dynamic pressure regulation mechanism and liquid reflux path. By setting a hemispherical or spherical baffle with a diameter slightly larger than the steam-water outlet, when the baffle is lifted under the action of steam or soup pressure, a controllable pressure relief channel is formed. This can not only quickly release high-pressure steam to avoid violent boiling caused by "explosive boiling", but also achieve self-adaptive closure when the baffle falls back by its own weight, precisely balancing the pressure fluctuations inside the pot. In the scenario of boiling water, the up-and-down reciprocating motion of the baffle forms intermittent exhaust, avoiding steam ejection caused by continuous high pressure; in scenarios with high overflow risks such as cooking porridge, after the soup is discharged through the steam-water outlet with the steam, it is naturally guided back into the pot under the guidance of the lower structure of the pot lid, rather than accumulating on the surface of the pot lid or overflowing onto the stove top; on the other hand, the temperature of the soup flowing out of the steam-water outlet onto the pot lid decreases, which helps to reduce the degree of boiling inside the pot after flowing back into the pot. In addition, vent holes are designed at the bottom of the baffle (such as holes in the sphere) to relieve the thermal expansion effect inside the baffle, ensuring that the sphere cannot burst and the reliability of the action execution. The size difference between the diameter of the baffle and the size of the steam-water outlet not only ensures the sealing performance but also allows a small displacement to trigger opening and closing, forming an intelligent response of "pressure threshold trigger". This design realizes dynamic pressure regulation without external intervention through a physical structure, completely solving the problem of pot overflow caused by uncontrollable exhaust of traditional fixed air holes, while taking into account the dual requirements of steam discharge efficiency and soup reflux guidance.

[0037] Embodiment Three;

[0038] As Figure 3 shown, the baffle is a connected baffle; the connected baffle is connected to the pot lid body through a connecting body 5 and is arranged at the steam-water outlet to cover or open the steam-water outlet. In this embodiment, the movable baffle 3 includes a top cover 4, the diameter of the top cover 4 is four centimeters and it is placed on the steam outlet with a diameter of three centimeters to cover the steam outlet. The connecting body 5 includes a connecting hole 6 opened on the top cover 4 and a cord 7 passing through the connecting hole 6. The cord can be threaded through the holes opened on the pot lid body for locking, realizing the movable connection of the baffle. Use a four-liter casserole and add three liters of water to boil water. Use a gas stove on high heat for direct fire heating. After heating for twenty minutes, the water boils, and the steam lifts the top cover and moves the baffle upward to open and release air outward. After that, the top cover repeatedly moves up and down to release air. When the fire is turned off and the water inside the casserole stops boiling, the top cover falls back onto the steam outlet. In order to improve the air release effect of the top cover 4 or to enhance the heat preservation effect, the top cover is a hollow double layer, and small holes are for preventing internal expansion. Vent holes 12 are opened on the top cover 4.

[0039] In other embodiments, the connector can adopt a folding shaft structure, including a fixed end and a mobile end: the fixed end is rigidly connected to the pot lid, and the mobile end is hinged to the top cover. When the steam pressure inside the casserole increases, the top cover rotates upward around the folding shaft under the thrust to open the steam and water outlet for pressure relief; after the pressure decreases, the top cover swings back and closes under the action of gravity. This shaft body design converts the steam kinetic energy into the directional swing of the top cover to achieve adaptive opening and closing. The top cover can be integrated with a handle for easy operation, and the overflowing soup is guided to the lower end of the pot lid through the steam and water outlet to avoid spilling. When using a four-liter casserole and adding three liters of water to boil it, use a gas stove on high heat for open fire heating. After heating for twenty minutes, the water boils, and the steam causes the top cover to open upward and release gas outward. When the fire is turned off, the water inside the casserole stops boiling, and the gas cover closes the steam outlet.

[0040] This connected baffle design has significant advantages over the solution in Embodiment 2 in terms of anti-overflow efficiency and structural optimization. Through the mechanical linkage of the folding shaft or cord, the steam kinetic energy is directly converted into the directional movement of the top cover, forming a precise control of "pressure trigger - instant response" to avoid the problems of delay or blockage of the steam and water outlet caused by liquid viscosity.

[0041] Embodiment 4;

[0042] As Figure 4 shown, an anti-overflow pot lid assembly includes a pot lid body 1, and a surrounding body 8 is detachably arranged upward at the position of the steam and water outlet 2. The surrounding body has a surrounding body passage, and the surrounding body passage communicates with the inner and outer spaces of the pot body separated from the steam and water outlet. The surrounding body passage has an upper port and a lower port. The upper port is located above the steam and water outlet, and the lower port coincides with the edge of the steam and water outlet. The coincidence methods include but are not limited to the port being fitted with the edge of the steam and water outlet, and also include a baffle 3. The baffle includes a non-connected baffle or a connected baffle; in this embodiment, the baffle 3 adopts the non-connected baffle shown in Embodiment 2. The structure and function of the non-connected baffle are the same as those in Embodiment 2 and will not be elaborated here. It should be noted that in this embodiment, the non-connected baffle is movably arranged in the surrounding body in a hemispherical shape, or the surrounding body can be not used, and the baffle can still be placed at the steam and water outlet for cooking to realize the opening and closing of the steam and water outlet. When the lower port coincides with the edge of the steam and water outlet, a receiving space for the liquid flowing out from the steam and water outlet is formed inside the surrounding body, that is, it can receive the water or soup flowing out from the steam and water outlet.

[0043] After setting the surrounding body, the distance for the soup to move upward is increased, and part of the soup that is about to overflow can naturally fall back into the pot under the action of gravity along the vertical passage, which can better avoid accumulation and overflow.

[0044] Alternatively, an anti-overflow pot lid assembly includes a pot lid body 1, and a surrounding body 8 is fixedly arranged upward at the position of the steam and water outlet 2. The pot lid is the lid of a casserole, and the surrounding body can be integrally fired with the pot lid, and the baffle is placed inside the surrounding body.

[0045] Embodiment five;

[0046] like Figure 5 The anti-overflow pot cover assembly shown includes a pot cover body 1, and a surrounding body 8 is detachably arranged upward at the position of the soda outlet 2, and the surrounding body has a surrounding body passage connecting the inner and outer spaces of the pot body separated by the soda outlet. The surrounding body passage has an upper port and a lower port, the upper port is located above the soda outlet 2, and the lower port is surrounded by the interior of the vertical projection space of the soda outlet. The accommodating space of the surrounding body gradually expands from the lower port to the upper port, forming a trumpet shape, and the lower port is located below the soda outlet. It also includes a baffle 3. In this embodiment, the baffle 3 also adopts the non-connecting baffle shown in the second embodiment. The non-connecting baffle is movably arranged in the surrounding body to realize the opening and closing of the soda outlet; or the surrounding body can be not used, and the baffle can still be placed at the soda outlet to cook.

[0047] Among them, the bell-shaped enclosure design significantly enhances the anti-overflow performance through fluid dynamics optimization and pressure gradient control: first, the lower port is arranged inside and below the vertical projection of the soda outlet, forming a low-pressure guide area. The overflowing steam and soup first enter the narrow lower port. Constrained by the gradually expanding structure of the bell-mouth, the flow rate gradually decreases and diffuses to the expanded upper port space, effectively buffering the injection kinetic energy and preventing the liquid from directly splashing out of the pot; second, the gradually expanding shape of the bell-mouth from bottom to top works synergistically with the non-connected baffle (such as a hemisphere). When the baffle is lifted by the steam, the expanded upper port provides a pressure release buffer zone to disperse the impact force of the steam. At the same time, the gradually expanding space guides the liquid to flow back to the lower port along the inner wall of the enclosure, and gravity is used to achieve directional liquid recovery; third, the lower port is located below the soda outlet and is directly connected to the inside of the pot, forming a closed overflow path, ensuring that the temporarily stored liquid can only flow back to the pot through the original path, avoiding the risk of lateral leakage of traditional enclosures.

[0048] Embodiment six;

[0049] like Figure 6As shown, what is different between this embodiment and other embodiments is that the lower port of the surrounding body surrounds the periphery of the vertical projection space of the steam and water outlet. In this embodiment, the surrounding space of the surrounding body 8 has the same diameter from the lower port to the upper port, and the diameter is larger than that of the steam and water outlet 2. In other embodiments, the surrounding body gradually expands from the lower port to the upper port to increase the collection area. This embodiment further includes a baffle 3. In this embodiment, the baffle 3 also adopts the connected baffle shown in Embodiment 3, and this connected baffle is movably arranged on the pot lid body 1 to realize the opening and closing of the steam and water outlet. It should be understood that the above-mentioned surrounding body 8 includes a surrounding body that can be fixedly arranged on the pot lid body 1 or a surrounding body that is movably arranged on the pot lid body 1 (separable). The surrounding body fixed on the pot lid body 1 can be used as a pot lid handle, and an outwardly drooping edge can be arranged at the upper end of the surrounding body. The surrounding drooping edge can flow the soup, ensuring that the place where the handle is held by hand is clean. Two surrounding bodies can be arranged on the pot lid body 1, including an additional surrounding body 8a that can be arranged. The additional surrounding body 8a includes a surrounding body that can be fixedly arranged on the pot lid body 1. The additional surrounding body 8a is arranged above or around the steam hole on the pot lid. The lower port of the surrounding body 8 includes a surrounding body that can be movably placed inside or outside the additional surrounding body 8a.

[0050] The additional surrounding body 8a (separable) movably arranged on the pot lid body 1 includes a lower port that can be fixedly or movably placed inside the surrounding body 8. The additional surrounding body 8a is arranged above or around the steam hole on the pot lid. In this embodiment, by surrounding the lower port around the vertical projection of the steam and water outlet, an annular overflow buffer zone is formed, forcing the steam and soup that were originally concentrated in the central jet to be dispersed to the peripheral path. The combined baffle (with a diameter larger than the steam and water outlet) reduces the impact speed through evenly distributed fluid resistance, avoiding liquid splashing caused by local high pressure.

[0051] Embodiment Seven;

[0052] As Figure 7 and Figure 8 shown, what is different between this embodiment and Embodiment Six is that the opening of the surrounding body 8 gradually expands from bottom to top. The surrounding body 8 is in the shape of a plate, or a water collecting platform 9 is integrally formed at the lower part of the surrounding body 8. The water collecting platform includes other shapes. For example, the water collecting platform of the surrounding body 8 in the shape of a plate is arc-shaped. The middle of the water collecting platform is opened to form the lower opening of the surrounding body 8. The lower opening can be sleeved above or around the steam and water outlet of the pot lid body 1 on the outside of the fixed surrounding body. The water collecting platform protrudes downward along the lower opening to form a lower annular enclosure 10. The lower annular enclosure can form an enclosure for the steam and water outlet 2 of the pot lid body 1 or the lower annular enclosure can be inserted into the steam and water outlet 2. It should be noted that when the diameter of the lower annular enclosure 10 is larger than the diameter of the steam and water outlet 2, other annular enclosures can be continuously added to the space surrounded by the lower annular enclosure. In addition, surrounding bodies can be continuously added, including fixed surrounding bodies that can be arranged above or around the steam and water outlet. The lower annular enclosure 10 can be sleeved on the outside of the fixed surrounding body or placed inside the fixed surrounding body. At the same time, as Figure 7As shown in the figure, in this embodiment, the baffle 3 also adopts the connected baffle shown in Embodiment 4. The connected baffle is movably arranged on the pot cover body 1 to realize the opening and closing of the steam and water outlet; or, Figure 8 In it, a movable baffle is adopted. The movable baffle can be placed at the steam and water outlet, or when the lower annular enclosure can be inserted into the interior of the steam and water outlet 2, the baffle is placed at the lower opening.

[0053] In this embodiment, the nested structure of the gradually expanding enclosure and the liquid collecting platform realizes the dual optimization of hierarchical pressure release and directional liquid recovery: First, the opening of the enclosure is designed to gradually expand from bottom to top in combination with the lower annular enclosure (the diameter is larger than or smaller than the steam and water outlet), forming a stepped overflow channel. The steam and soup first enter the narrow lower port. Constrained by the gradually expanding space, the flow rate gradually decreases and diffuses to the upper enlarged accommodating area, effectively buffering the high-pressure jet kinetic energy; Second, the synergistic effect of the liquid collecting platform and the lower annular enclosure forcibly confines the overflow liquid within the annular space surrounded by the enclosure, and guides the liquid to flow back into the pot along the surface of the platform by gravity, avoiding the lateral splashing or residue of the liquid in the traditional design; Third, the nested design of the multi-layer annular enclosures can set a fixed enclosure on the pot cover (such as adding an additional enclosure with a matching size), and the overflow capacity can be dynamically adjusted according to the cooking pressure to achieve adaptive pressure grading control. The rigid closure of the connected baffle further ensures the sealing reliability and avoids micro-pressure leakage.

[0054] Embodiment 8;

[0055] As Figure 9 shown, different from Embodiment 6, the opening of the enclosure 8 gradually shrinks from bottom to top, forming a state of being inverted on the pot cover body 1. The upper opening of the enclosure 8 is convexly provided with an upper annular enclosure 11. The upper annular enclosure 11 forms an enclosure for the steam and water outlet 2 of the pot cover body 1. The upper annular enclosure 11 can serve as a handle of the enclosure. Additional enclosures can be continuously added, including that a fixed enclosure can be provided above or around the steam and water outlet. The lower annular enclosure 10 is sleeved outside the fixed enclosure or placed inside the fixed enclosure. In this embodiment, the baffle 3 also adopts the connected baffle shown in Embodiment 3. The connected baffle is movably arranged on the pot cover body 1, and a baffle may not be provided at the upper annular enclosure 11 of the enclosure, or another connected baffle can be provided. This embodiment forms an inverted gradually expanding enclosure, and the upper annular enclosure plays a role in preventing the lateral splashing or residue of the liquid. The inverted gradually expanding enclosure can realize the guiding and recycling effect of the liquid juice. Note that the splashed liquid can flow back to the pot cover body 1 along the surface of the inverted gradually expanding enclosure. At the same time, in order to prevent dust, the center of the pot cover can be made flat or concave, and a fixed enclosure is provided at the flat or concave part. The lower annular enclosure 10 is placed inside the fixed enclosure, and the soup flowing into the enclosure can also flow back into the pot through the steam and water outlet. This embodiment includes that the upper annular enclosure 11 or the lower annular enclosure 10 may not be provided, and the upper opening or the lower opening of the enclosure 8 can also complete the above functions.

[0056] The lid body in all the above embodiments can be fired into the target shape using clay. The materials of the surrounding body and the baffle body other than this can be stainless steel or clay. Among them, the material of the baffle body can also be wood (cork). In order to prevent loss, they can all be additionally connected to the lid body with a connecting rope. At the same time, the present invention also discloses a supporting anti-overflow stew pot, which includes a pot body adapted to the lid assembly. The pot body is also preferably made of clay to maintain consistent thermal performance. The lid body covers the pot mouth by its own weight or a snap structure, ensuring that steam and liquid can only be discharged directionally through the steam-water outlet during the cooking process. Through material coordination and structural matching in the overall design, while maintaining the cooking flavor of traditional casseroles, it realizes a comprehensive improvement in anti-overflow, energy conservation and safety.

[0057] Embodiment Nine;

[0058] As Figure 10 shown, the baffle body 3 can be a limiting baffle body. This baffle body includes a baffle body and a limiting device connected to the baffle body. The limiting device is placed inside the steam-water outlet. Among them, the baffle body 3 is located above the steam-water outlet 1, and the limiting device is located inside or below the steam-water outlet. When the steam or soup lifts the baffle body, the baffle body rises to open the steam-water outlet, exhausting gas or flowing out the soup. The limiting device is restricted by the blocking effect of the steam-water outlet to prevent the baffle body from completely detaching from the steam-water outlet;

[0059] The limiting device includes a strip-shaped or plate-shaped connecting member 13, and a ring-shaped, rod-shaped or sheet-shaped limiting body 14. The limiting body 14 is connected to the baffle body 3 through the connecting member 13, and the three are fixedly connected. Of course, the connecting member and the limiting body are not limited to the above shapes. For example, a ring-shaped or cylindrical connecting member can also be used. Among them, the number of connecting members can be adjusted by itself. In this embodiment, the connecting member 13 is strip-shaped and the number is three; as long as the limiting body is connected inside the steam-water outlet, for example, a hook-shaped limiting body can also be used. As long as the limiting body can abut against the steam-water outlet when the baffle body rises to prevent the baffle body from completely detaching from the steam-water outlet. In this embodiment, the limiting body 14 is ring-shaped; of course, in this case, the baffle body in this embodiment also serves as a lid handle.

[0060] It should be noted that the baffle 3 in this embodiment belongs to a non-connected baffle, and the baffle 3 is detachably arranged at the steam-water port to close or open the steam-water port. Through the collaborative design of the baffle and the limiting device, this embodiment realizes the controllable movement and anti-detachment function of the baffle. The limiting device consists of a connecting piece and a limiting body. Through the physical barrier on the inner wall of the steam-water port, it is ensured that the baffle can only be lifted to a preset height after being jacked up by steam, which not only guarantees the smoothness of exhaust / drainage, but also avoids the risk of loss caused by the baffle completely detaching. The baffle also has the function of a handle, improving the operation convenience; the rigid structure design of multiple connecting pieces enhances the stability of the device, especially suitable for high-pressure cooking scenarios. The diverse forms of the limiting body are adapted to steam-water ports of different sizes, taking into account flexibility, safety and durability.

[0061] Embodiment Ten;

[0062] As Figure 11 shown, the baffle 3 can be a limiting baffle and also belongs to a non-connected baffle. Compared with Embodiment Nine, the limiting body 14 is omitted, and the connecting piece 13 is retained. The connecting piece 13 is fixedly connected to both sides of the steam-water port, and the connecting piece 13 movably penetrates through the baffle 3. The cross bar of the connecting piece 13 is located above the baffle 3, and the cross bar limits the baffle when the baffle rises; in this case, either the baffle 3 or the connecting piece 13 in this embodiment can be used as the pot lid handle.

[0063] It should be noted that the baffle 3 in this embodiment belongs to a non-connected baffle, and the baffle 3 is detachably arranged at the steam-water port to close or open the steam-water port. This embodiment adopts a simplified limiting structure, and through the connecting piece and cross bar fixed on both sides of the steam-water port for limiting, it realizes the directional lifting and anti-detachment function of the baffle. After omitting the independent limiting body, the structural complexity is significantly reduced, reducing the manufacturing cost and maintenance difficulty, while retaining the core anti-overflow ability. This design ensures that the baffle can be reliably reset after the pressure is released, simplifying the assembly process; the design of directly using the baffle or the connecting piece as the handle further optimizes the use flexibility. This solution is especially suitable for scenarios that are sensitive to cost and require quick cleaning, meeting the dual requirements of efficient anti-overflow and user-friendliness through a minimalist structure.

[0064] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
