Description

Technical Field

[0001] This utility model relates to a stew pot, and more particularly to a pot lid assembly and a stew pot. Background Technology

[0002] As a traditional cooking utensil, the earthenware pot has gradually become a widely used cooking utensil in homes and the catering industry due to its excellent heat retention, even heating, rich flavor of stewed food, and lack of metal leaching. However, existing earthenware pots have significant defects in their anti-overflow design, seriously affecting user experience and safety, specifically manifested in the following problems:

[0003] "Explosive boiling" can cause soup to overflow and pose safety hazards. Clay pots heat up slowly and have heavy lids, making them prone to violent boiling due to a sudden increase in internal pressure during continuous heating (i.e., "explosive boiling"). At this time, a large amount of soup or steam will rapidly spray out through the vents in the lid, which will not only stain the kitchen countertop but may also extinguish the open flame on the stove, leading to safety hazards such as gas leaks.

[0004] Traditional vent designs are inefficient. Existing clay pot lids have fixed, open vents that cannot dynamically adjust the amount of steam released based on the pressure inside the pot. When boiling, the steam released directly from the vents carries liquid droplets and can easily spray over long distances (up to 1 meter or more), significantly increasing the difficulty of cleaning. In addition, overflowing soup flows down the outer wall of the pot onto the stove, further exacerbating the cleaning burden.

[0005] The inconvenience and risks arising from compromised user operation methods often force users to adopt abnormal operating methods such as "cooking with the lid off" or "closing the lid at an off-center position" to avoid overflowing. The former significantly prolongs cooking time and reduces thermal efficiency; the latter, because the lid is easily pushed back into place by steam, leads to the risk of secondary overflow, making it difficult to fundamentally solve the problem.

[0006] Currently, most commercially available clay pots lack reliable anti-overflow devices, and users urgently need anti-overflow clay pots that combine safety, convenience, and efficiency. The deficiencies in existing technology have become a key factor restricting the further popularization of clay pots. Based on these issues, there is an urgent need for an anti-overflow lid and stew pot solution that can improve the safety and convenience of using clay pots and meet market demands. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this utility model provides a pot lid assembly and a stew pot.

[0008] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0009] An anti-overflow pot lid assembly includes an anti-overflow pot lid, which includes a pot lid body. A steam outlet is provided vertically through the center of the pot lid body to discharge steam or soup from inside the pot. The steam outlet is an automatically opening and closing steam outlet, which is formed by a baffle that is provided on the steam outlet and moves upward when pushed by steam or liquid.

[0010] Furthermore, the baffle includes a non-connecting baffle or a connecting baffle; the non-connecting baffle is detachably disposed at the water inlet to close or open the water inlet; the connecting baffle is connected to the pot lid body via a connector and disposed at the water inlet to cover or open the water inlet.

[0011] An anti-overflow pot lid assembly includes an anti-overflow pot lid, which includes a pot lid body. A steam outlet is provided vertically through the center of the pot lid body to discharge steam or soup from inside the pot. A surrounding body is provided upward at the location of the steam outlet, and the surrounding body has a surrounding passage that connects the inner and outer spaces of the pot body separated by the steam outlet.

[0012] Furthermore, the enclosure passage has an upper port and a lower port. The upper port is located above the water inlet, and the lower port coincides with the edge of the water inlet. Alternatively, the lower port may be located outside the vertical projection space of the water inlet or inside the vertical projection space of the water inlet.

[0013] Furthermore, it also includes a baffle, which may be a non-connecting baffle or a connecting baffle; the non-connecting baffle can be detachably disposed on the enclosure passage to close or open the space connecting the inside and outside of the pot; the connecting baffle is connected to the enclosure passage through a connector and disposed on the enclosure passage to close or open the space connecting the inside and outside of the pot.

[0014] Furthermore, when the edge of the lower port coincides with the edge of the soda spout, a space is formed within the enclosure to contain the liquid flowing out of the soda spout.

[0015] Furthermore, when the lower port is positioned around the vertical projection space of the water inlet, the accommodating space of the baffle gradually expands from the lower port to the upper port.

[0016] Furthermore, when the lower port is located inside the vertical projection space of the water inlet, the accommodating space of the baffle gradually expands from the lower port to the upper port, with the lower port located below the water inlet.

[0017] A stew pot includes a pot body and an anti-overflow lid assembly, with the lid body covering the pot body.

[0018] This utility model discloses a pot lid assembly and a stew pot. Through innovative design, it effectively solves problems such as overflowing broth, steam jetting, and safety hazards associated with traditional clay pot stewing. Its core advantages lie in the coordinated operation of a centrally located steam inlet and an automatically opening and closing baffle. This automatically releases pressure when the pressure inside the pot increases, preventing violent boiling and reducing the risk of gas leakage. The gradually expanding or annular enclosure structure guides overflowing broth back into the pot under gravity, significantly reducing countertop contamination and cleaning burden. The adaptive pressure control design supports fully enclosed cooking, avoiding manual intervention while improving thermal efficiency, shortening cooking time, and reducing heat waste. It offers diverse structures such as non-connected baffles, connected baffles, and graded buffer enclosures to flexibly adapt to different scenarios such as cooking porridge, boiling water, and stewing soup. Through physical structural innovation, this utility model achieves synergistic optimization of pressure control, liquid reflux, and heat utilization, combining safety, convenience, and energy efficiency. It is suitable for home and catering scenarios and has significant market value and social benefits. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1;

[0033] like Figure 1 The illustrated anti-overflow pot lid includes a lid body 1. A steam vent 2 is vertically oriented along the center of the lid body 1, allowing steam or broth to escape from the pot. The diameter of the steam vent is typically 1.5 cm, but the size is not limited to this. This centrally located arrangement creates a vertically oriented structure, utilizing the natural force of rising steam to discharge it. Simultaneously, the steam vent serves the dual function of releasing steam and broth. When the pressure inside the pot increases, steam is released first to reduce the risk of boiling over. Some broth that is about to overflow can naturally fall back into the pot under gravity along the vertical path, preventing accumulation and overflow. Some broth, after flowing out of the steam vent, flows back into the pot through the lid surface, preventing further overflow. Furthermore, the centrally located steam vent creates a symmetrical design, which helps balance the internal pressure distribution of the pot, significantly improving the anti-overflow effect. In other embodiments, the location of the steam outlet 2 may include setting the steam outlet off-center from the center of the lid or on the sloping surface of the lid. This still allows the steam to be released preferentially when the pressure inside the pot increases, thereby reducing the risk of boiling over. Alternatively, some soup may flow out of the steam outlet and then back into the pot through the surface of the lid, preventing the soup from overflowing. This also serves to prevent the soup from overflowing.

[0034] Example 2;

[0035] like Figure 2The illustrated anti-overflow pot lid assembly includes the anti-overflow pot lid disclosed in Embodiment 1. The steam outlet is an automatically opening and closing steam outlet 2, which is formed on a baffle 3 that is provided on the steam outlet and moves upward by steam or liquid. In this embodiment, the diameter of the steam inlet 2 at the center 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 serves as a non-connecting baffle. In other embodiments, the hemisphere can be replaced with a sphere, or other shapes such as a conical baffle, but its diameter should be larger than the diameter of the steam inlet 2. When the baffle is a sphere, a hole can be provided in the sphere to prevent thermal expansion, and the lower part of the sphere is placed inside the steam inlet. In a specific implementation, a four-liter casserole is filled with three liters of water and heated over a high flame on a gas stove. After heating for twenty minutes, the water boils, and the steam pushes the sphere upwards, causing the baffle to open and release steam. When the sphere reaches its maximum position, it moves downwards. The sphere then repeatedly moves up and down to release steam. When the heat is turned off, the water inside the casserole stops boiling, and the sphere falls back onto the steam inlet. A handle for the pot lid is provided separately. The broth flowing from the steam outlet is allowed to drain to the bottom of the lid. Use a four-liter clay pot with three liters of water and 200 grams of rice to cook porridge. Heat over a high flame on a gas stove. After twenty minutes, the water boils, and the steam pushes the sphere upwards. The baffle opens to release steam and broth. When the sphere reaches its maximum position, it moves downwards. The sphere is then pushed up or repeatedly moves up and down. After heating over low heat, the sphere repeatedly moves up and down to release steam and broth, which flows into the pot through the bottom of the lid. When the heat is turned off, the water inside the clay pot stops boiling, and the sphere falls back onto the steam outlet. Note that the pressure inside the clay pot can be controlled and adjusted by setting the weight of the baffle.

[0036] The core advantage of this anti-overflow lid assembly lies in the synergistic effect of its dynamic pressure regulation mechanism and liquid return path. By setting a hemispherical or spherical baffle with a diameter slightly larger than the water inlet, the baffle forms a controllable pressure relief channel when it is lifted by the pressure of steam or soup. This not only quickly releases high-pressure steam to avoid violent boiling caused by "explosive boiling," but also achieves adaptive closure by the baffle's own weight, precisely balancing pressure fluctuations inside the pot. In the scenario of boiling water, the up-and-down reciprocating motion of the baffle creates intermittent venting, avoiding steam jets caused by continuous high pressure. In scenarios with a high risk of overflow, such as cooking porridge, the soup, after being discharged through the water inlet with the steam, is guided by the structure at the bottom of the lid to naturally flow back into the pot, rather than accumulating on the lid surface or overflowing onto the stove. On the other hand, the temperature of the soup flowing from the water inlet onto the lid is reduced, which helps to reduce the degree of boiling inside the pot after it flows back in. Furthermore, the vent holes at the bottom of the baffle (similar to holes in a sphere) mitigate the thermal expansion effect inside the baffle, ensuring the sphere won't burst and guaranteeing reliable operation. The difference in diameter between the baffle and the water inlet ensures both sealing and allows for slight displacement to trigger opening and closing, creating a "pressure threshold trigger" intelligent response. This design achieves dynamic pressure control without external intervention through physical structure, completely solving the overflow problem caused by uncontrollable venting in traditional fixed vents, while simultaneously addressing the dual needs of efficient steam emission and guiding broth backflow.

[0037] Example 3;

[0038] like Figure 3 The baffle shown is a connecting baffle; the connecting baffle is connected to the pot lid body via a connector 5 and is positioned at the steam inlet to cover or open the steam inlet. In this embodiment, the movable connecting baffle 3 includes a top cover 4, the top cover 4 having a diameter of four centimeters, which is placed on the steam inlet with a diameter of three centimeters to cover the steam inlet. The connector 5 includes a connecting hole 6 on the top cover 4 and a rope 7 passing through the connecting hole 6. The rope can be threaded through the hole on the pot lid body for locking, realizing the movable connection of the baffle. A four-liter casserole is filled with three liters of water and heated over a gas stove at high heat. After heating for twenty minutes, the water boils, and the steam pushes the top cover upward, opening the baffle to release steam. The top cover then repeatedly moves up and down to release steam. When the heat is turned off, the water inside the casserole stops boiling, and the top cover falls back onto the steam inlet. To improve the venting effect of the top cover 4 or to enhance the heat preservation effect, the top cover is hollow and double-layered. Small holes 12 are provided on the top cover 4 to prevent internal expansion.

[0039] In other embodiments, the connecting body can adopt a folding shaft structure, including a fixed end and a moving end: the fixed end is rigidly connected to the pot lid, and the moving end is hinged to the top lid. When the steam pressure inside the casserole increases, the top lid is pushed upward around the folding shaft, opening the steam vent to release pressure; after the pressure decreases, the top lid swings back and closes under the action of gravity. This shaft design converts the kinetic energy of steam into the directional swing of the top lid, realizing adaptive opening and closing. The top lid can be integrated with a handle for easy operation, and overflowing soup is guided through the steam vent to the lower end of the pot lid to flow back, preventing spillage. Using a four-liter casserole with three liters of water, heat it over a gas stove on a high flame. After heating for twenty minutes, the water boils, and the steam causes the top lid to open upward to release steam. When the heat is turned off, the water inside the casserole stops boiling, and the steam vent closes.

[0040] Compared to the solution in Embodiment 2, this connecting baffle design has significant advantages in terms of anti-overflow performance and structural optimization. Through the mechanical linkage of the folding shaft or rope, the steam kinetic energy is directly converted into the directional movement of the top cover, forming a precise control of "pressure trigger - instant response", avoiding the delay or blockage problem caused by liquid viscosity at the steam outlet.

[0041] Example 4;

[0042] like Figure 4 The illustrated anti-overflow pot lid assembly includes a pot lid body 1 and a detachable enclosure 8 disposed upwards at the location of the water inlet 2. The enclosure has an enclosure passage that connects the inner and outer spaces of the pot body separated by the water inlet. The enclosure passage has an upper port and a lower port. The upper port is located above the water inlet, and the lower port coincides with the edge of the water inlet. The coincidence can be, but is not limited to, the port fitting into the edge of the water inlet. The assembly also includes a baffle 3, which can be a non-connected baffle or a connected baffle. In this embodiment, the baffle 3 is a non-connected baffle as shown in Embodiment 2. The structure and function of the non-connected baffle are the same as in Embodiment 2, and will not be described in detail here. It should be noted that in this embodiment, the non-connected baffle can be hemispherically mounted within the enclosure, or the enclosure can be omitted, and cooking can still be carried out by placing the baffle at the water inlet, thus achieving the opening and closing of the water inlet. When the edge of the lower port coincides with the edge of the water spout, a space is formed inside the enclosure to accommodate the liquid flowing out of the water spout, that is, it can accommodate water or soup flowing out of the water spout.

[0043] The enclosure increases the distance the soup travels upwards, allowing any overflowing soup to fall back into the pot naturally under gravity along the vertical path, thus better preventing accumulation and spillage.

[0044] Alternatively, an anti-overflow pot lid assembly includes a pot lid body 1 with a surrounding body 8 fixedly mounted upward at the position of the water inlet 2, including a pot lid that is a clay pot lid, the surrounding body being integrally fired with the pot lid, and a baffle placed inside the surrounding body.

[0045] Example 5;

[0046] like Figure 5 The illustrated anti-overflow pot lid assembly includes a lid body 1 and a detachable enclosure 8 disposed upwards at the location of the water inlet 2. The enclosure has a passageway connecting the inner and outer spaces of the pot body separated from the water inlet. The enclosure passageway has an upper port and a lower port. The upper port is located above the water inlet 2, and the lower port is located inside the vertical projection space of the water inlet. The accommodating space of the enclosure gradually expands from the lower port to the upper port, forming a funnel shape. The lower port is located below the water inlet. It also includes a baffle 3. In this embodiment, the baffle 3 is also a non-connected baffle as shown in Embodiment 2. This non-connected baffle is movably disposed within the enclosure to open and close the water inlet; alternatively, the enclosure can be omitted, and cooking can still be carried out by placing the baffle at the water inlet.

[0047] The trumpet-shaped enclosure design significantly enhances spill prevention performance through fluid dynamics optimization and pressure gradient control: First, the lower port is located inside and below the vertical projection of the steam and water inlet, forming a low-pressure guiding zone. Overflowing steam and soup first enter the narrow lower port, and constrained by the gradually expanding structure of the trumpet, the flow velocity gradually decreases and diffuses to the expanded upper port space, effectively buffering the jet kinetic energy and preventing liquid from splashing directly outside the pot. Second, the gradually expanding shape of the trumpet from bottom to top works in conjunction with the non-connected baffle (such as a hemisphere). When the baffle is lifted by steam, the expanded upper port provides a pressure release buffer zone, dispersing the steam impact force. At the same time, the gradually expanding space guides the liquid to flow back along the inner wall of the enclosure to the lower port, using gravity to achieve directional liquid recovery. Third, the lower port is located below the steam and water inlet 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 into the pot through the original path, avoiding the risk of lateral leakage of traditional enclosures.

[0048] Example 6;

[0049] like Figure 6As shown, this embodiment differs from other embodiments in that the lower port of the enclosure surrounds the vertical projection space of the water spout. In this embodiment, the diameter of the enclosure 8 is consistent from the lower port to the upper port, and is larger than the diameter of the water spout 2. In other embodiments, the enclosure gradually expands from the lower port to the upper port to increase the collection area. This embodiment also includes a baffle 3. In this embodiment, the baffle 3 also adopts the connecting baffle shown in Embodiment 3. This connecting baffle is movably mounted on the pot lid body 1 to realize the opening and closing of the water spout. It should be understood that the above-mentioned enclosure 8 includes an enclosure that can be fixedly mounted on the pot lid body 1 or an enclosure that can be movably mounted on the pot lid body 1 (separable). The enclosure fixed on the pot lid body 1 can serve as a pot lid handle. An outwardly drooping edge can be provided at the upper end of the enclosure, allowing soup to flow out and ensuring that the handle is clean. Two enclosures can be provided on the pot lid body 1, including an additional enclosure 8a. The additional enclosure 8a can be fixedly provided on the pot lid body 1. The additional enclosure 8a is provided above or around the steam hole on the pot lid. The lower port of the enclosure 8a can be movably placed inside or outside the additional enclosure 8a.

[0050] An additional enclosure 8a (detachable) is movably mounted on the pot lid body 1. This enclosure includes a lower port that can be fixedly or movably placed inside the enclosure 8a. The additional enclosure 8a is positioned above or around the steam / water outlet on the pot lid. In this embodiment, the lower port surrounds the vertical projection of the steam / water outlet, forming an annular overflow buffer zone. This forcibly disperses the steam and broth originally concentrated in the center of the spray to the outer path. The combined baffle (with a diameter larger than the steam / water outlet) reduces the impact velocity through uniformly distributed fluid resistance, preventing liquid splashing caused by localized high pressure.

[0051] Example 7;

[0052] like Figure 7 and Figure 8 As shown, this embodiment differs from Embodiment Six in that the opening of the enclosure 8 gradually expands from bottom to top. The enclosure 8 is plate-shaped, or the lower part of the enclosure 8 is integrally formed with a water collection platform 9. The water collection platform can include other shapes, such as an arc-shaped water collection platform in the plate-shaped enclosure 8. The central opening of the water collection platform forms the lower opening of the enclosure 8. The lower opening can be fitted over the water inlet or outside the fixed enclosure. A lower annular barrier 10 protrudes downward along the lower opening of the water collection platform. The lower annular barrier can surround the water inlet 2 of the pot lid body 1, or the lower annular barrier can be inserted into the interior of the water inlet 2. Note that when the diameter of the lower annular barrier 10 is larger than the diameter of the water inlet 2, other annular barriers can be added within the space surrounded by the lower annular barrier. In addition, enclosures can be added, including a fixed enclosure that can be set above or around the water inlet, and the annular barrier 10 can be fitted over the fixed enclosure or placed inside the fixed enclosure. At the same time, as Figure 7As shown, in this embodiment, the baffle 3 also adopts the connecting baffle shown in Embodiment 4. This connecting baffle is movably mounted on the pot lid body 1 to realize the opening and closing of the water inlet; or, Figure 8 The middle part adopts a movable baffle, which can be placed at the water inlet, or when the lower ring baffle can be inserted into the water inlet 2, the baffle is placed at the lower opening.

[0053] This embodiment achieves dual optimization of graded pressure release and directional liquid recovery through a nested structure of a gradually expanding enclosure and a water collection platform: First, the enclosure opening gradually expands from bottom to top, combined with a lower annular baffle (with a diameter larger or smaller than the steam / water inlet), forming a stepped overflow channel. Steam and broth first enter the narrow lower port, and constrained by the gradually expanding space, the flow velocity gradually decreases and diffuses to the upper expanded containment area, effectively buffering the kinetic energy of the high-pressure jet; Second, the synergistic effect of the water collection platform and the lower annular baffle forcibly confines the overflow liquid within the annular space surrounded by the baffle, guiding the liquid back into the pot along the platform surface by gravity, avoiding horizontal splashing or residue of liquid in traditional designs; Third, the nested design of multiple annular baffles allows for the installation of a fixed enclosure on the pot lid (such as adding an additional baffle of matching size), which can dynamically adjust the overflow capacity according to the cooking pressure, achieving adaptive pressure graded control. The rigid closure of the connecting baffles further ensures sealing reliability and avoids micro-pressure leakage.

[0054] Example 8;

[0055] like Figure 9 As shown, unlike Embodiment Six, the opening of the enclosure 8 gradually narrows from bottom to top, forming an inverted position on the pot lid body 1. The upper opening of the enclosure 8 has an upper annular barrier 11 protruding upwards, which surrounds the water inlet 2 of the pot lid body 1. The upper annular barrier 11 can serve as a handle for the enclosure. The enclosure can be further expanded, including a fixed enclosure that can be set above or around the water inlet. The lower annular barrier 10 can be placed outside the fixed enclosure or inside the fixed enclosure. In this embodiment, the barrier 3 also adopts the connecting barrier shown in Embodiment Three. The connecting barrier is movably set on the pot lid body 1, while the barrier at the upper annular barrier 11 of the enclosure may not be provided, or another connecting barrier may be provided. This embodiment features an inverted, gradually expanding enclosure. The upper annular barrier prevents liquid from splashing or remaining laterally. The inverted, gradually expanding enclosure also guides and recovers the liquid. Note that splashed liquid can be guided back onto the lid body 1 along the surface of the inverted, gradually expanding enclosure. To prevent dust accumulation, the center of the lid can be flat or concave. A fixed enclosure is installed at the flat or concave location, and the lower annular barrier 10 is placed inside the fixed enclosure. Liquid flowing into the enclosure can also flow back into the pot through the spout. This embodiment also allows for the optional use of either the upper or lower annular barrier 10; the upper or lower opening of the enclosure 8 can still achieve the same functions.

[0056] In all the above embodiments, the lid body can be made of clay and fired to the desired shape. The surrounding body and baffle can be made of stainless steel or clay, with the baffle also potentially made of wood (cork). To prevent loss, a connecting rope can be used to connect them to the lid body. This invention also discloses a matching anti-overflow stew pot, including 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 fits the pot opening via its own weight or a snap-fit ​​structure, ensuring that steam and liquid can only be released directionally through the steam / water inlet during cooking. The overall design, through material synergy and structural matching, maintains the flavor of traditional clay pot cooking while achieving a comprehensive improvement in anti-overflow, energy saving, and safety.

[0057] Example 9;

[0058] like Figure 10 As shown, the baffle 3 can be a limiting baffle, which includes a baffle and a limiting device connected to the baffle. The limiting device is placed inside the steam outlet, where the baffle 3 is located above the steam outlet 1 and the limiting device is located inside or below the steam outlet. When steam or soup pushes up the baffle, the baffle rises and opens the steam outlet to release air or allow soup to flow out. The limiting device is blocked by the steam outlet, preventing the baffle from completely detaching from the steam outlet.

[0059] The limiting device includes a strip-shaped or plate-shaped connector 13 and a ring-shaped, rod-shaped, or sheet-shaped limiting body 14. The limiting body 14 is connected to the stop body 3 through the connector 13, and the three are fixedly connected. Of course, the connector and the limiting body are not limited to the above shapes. For example, a ring-shaped or cylindrical connector can also be used. The number of connectors can be adjusted. In this embodiment, the connector 13 is strip-shaped and there are three of them. The limiting body can be connected inside the steam outlet. For example, a hook-shaped limiting body can also be used. As long as the stop body is raised, the limiting body can abut against the steam outlet to prevent the stop body from completely detaching from the steam outlet. In this embodiment, the limiting body 14 is ring-shaped. Of course, in this case, the stop body in this embodiment is also used as a pot lid handle.

[0060] It should be noted that the baffle 3 in this embodiment is a non-connected baffle, which can be detachably installed at the steam inlet to close or open the steam inlet. This embodiment achieves controllable movement and anti-detachment functions of the baffle through the coordinated design of the baffle and the limiting device. The limiting device consists of a connector and a limiting body. Through the physical barrier of the inner wall of the steam inlet, it ensures that the baffle can only rise to a preset height after the steam rises, ensuring smooth venting / draining while avoiding the risk of loss due to complete detachment. The baffle also functions as a handle, improving ease of operation; the rigid structure design of the multiple connectors enhances the stability of the device, making it particularly suitable for high-pressure cooking scenarios. The diverse shapes of the limiting body adapt to different sizes of steam inlets, balancing flexibility, safety, and durability.

[0061] Example 10;

[0062] like Figure 11 As shown, the baffle 3 can be a limiting baffle or a non-connecting baffle. Compared with embodiment nine, the limiting body 14 is omitted, and the connector 13 is retained. The connector 13 is fixedly connected to both sides of the water spout. The connector 13 is movably inserted through the baffle 3. The crossbar of the connector 13 is located above the baffle 3. When the baffle is raised, the crossbar limits the baffle. In this case, either the baffle 3 or the connector 13 in this embodiment can be used as a pot lid handle.

[0063] It should be noted that the baffle 3 in this embodiment is a non-connected baffle, which can be detachably installed at the water inlet to close or open the water inlet. This embodiment adopts a simplified limiting structure, using connectors and crossbars fixed to both sides of the water inlet to limit the directional lifting and anti-detachment functions of the baffle. By eliminating the independent limiting body, the structural complexity is significantly reduced, lowering manufacturing costs and maintenance difficulty, while retaining the core anti-overflow capability. This design ensures that the baffle reliably resets after pressure release, simplifying the assembly process; the design of the baffle or connector directly serving as a handle further optimizes the flexibility of use. This solution is particularly suitable for cost-sensitive scenarios that require rapid cleaning, achieving both efficient anti-overflow and user-friendliness through a minimalist structure.

[0064] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
