At this time, the cover body is located below the exhaust structure, so that the upper surface of the cover body is lower than the supporting ring, thereby forming a reflux space with a certain height above the cover body. The reflux space is exposed to the outside of the pot body, and even if the soup or foam in the pot overflows, it can be quickly cooled down in the reflux space and flow back into the pot. It can effectively avoid problems such as countertop contamination caused by overflow, and can also flow the liquid with lower temperature back into the pot to cool down the soup in the pot, thereby lowering the liquid level in the pot.

[0047] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0051] like Figure 1-Figure 7 As shown, the embodiment of the present application provides a cooker, which includes a pot cover and a pot body 8, the pot cover covers the pot mouth of the pot body 8, and the pot cover includes a support ring 1 and a cover body 2. The support ring 1 is used to cooperate with the pot body 8 so that the pot cover can cover the pot body 8, an opening is formed on the inner side of the support ring 1, and an exhaust structure (for example, an exhaust hole 4, an exhaust gap or an exhaust channel, etc.) is provided below the opening; the cover body 2 is movably connected to the support ring 1 and can move along the axial direction of the support ring 1 to open or close the exhaust structure. When the cover body 2 is located above the exhaust structure, the cover body 2 closes the opening, thereby forming a heat-insulating state for the pot cover and improving the cooking speed; when the cover body 2 is located below the exhaust structure, the exhaust structure connects the inner and outer sides of the cover body 2, thereby forming a exhaust state for the pot cover, meeting the exhaust requirements and preventing the soup in the pot from overflowing. In addition, at this time, the cover body 2 is located below the exhaust structure, so that the upper surface of the cover body 2 is lower than the support ring 1, thereby forming a reflux space with a certain height above the cover body 2, and the reflux space is exposed to the outside of the pot body 8. Even if the soup or foam in the pot overflows, it can be quickly cooled down in the reflux space and flow back into the pot, which can effectively avoid problems such as countertop contamination caused by overflow, and can also flow the liquid with lower temperature back into the pot to cool the soup in the pot, thereby lowering the liquid level in the pot.

[0052] Furthermore, the pot cover also includes a cover head 5, which is connected to the top of the cover body 2, for example, the cover head 5 is connected to the cover body 2 by fasteners such as screws 6. When the cover body 2 sinks into the opening, at least a portion of the cover head 5 protrudes from the top of the support ring 1, that is, the user can hold the cover head 5 outside the height range of the support ring 1 to lift the cover body 2 or the pot cover, thereby preventing the overflowing steam from scalding the user.

[0053] In one embodiment, reference Figure 7 , a support sleeve 7 is sandwiched between the cover head 5 and the cover body 2, that is, the support sleeve 7 extends along the axial direction of the cover body 2, and the cover head 5 and the cover body 2 are respectively pressed against the two ends of the support sleeve 7, and the axial distance between the cover head 5 and the cover body 2 is increased by the support sleeve 7, so that the original cover head 5 is raised, without changing the original structure of the cover head 5 and the cover body 2, and only the length of the fasteners such as the screw 6 is increased, which is easy to implement and has a low production cost. It can be understood that in other embodiments, the cover head 5 itself can also be extended axially so that the top of the cover head 5 extends out of the top of the support ring 1.

[0054] like Figure 1-Figure 6 As shown, further, the diameter of the opening is d, the diameter of the pot mouth is D, and the value range of d / D is 0.4~0.8. For example, the value of d / D can be 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75 or 0.8, which can effectively prevent the accumulation of soup or foam and achieve a reliable anti-overflow effect. When the value of d / D is less than 0.4, the cross-section of the reflux space between the cover body 2 and the support ring 1 is small, and the soup or foam is easy to accumulate to a high height in the reflux space, affecting the exhaust effect and the reflux effect, and also causing the soup or foam to immerse and pollute the cover head, or causing the temperature of the cover head to be too high and scald the user; when the value of d / D is greater than 0.8, the gap between the exhaust structure and the pot wall is too small, and the soup or foam is easy to accumulate to a high height between the exhaust structure and the pot wall. Under the influence of factors such as air flow impact or violent boiling, the soup or foam in the pot is easy to overflow the top of the pot body 8.

[0055] Furthermore, when the cover body 2 is located below the exhaust structure, at least a portion of the cover body 2 can sink into the pot body 8, thereby venting and overflowing within the height range of the pot body 8, avoiding the liquid level from rising to the top of the pot body 8, and effectively preventing soup or foam from overflowing along the top of the pot body 8.

[0056] Furthermore, when the lid 2 sinks into the pot body 8, the height difference between the lowest point of the lid and the highest point of the pot body 8 is h, and the value range of h is 2 cm to 6 cm. For example, the value of h can be 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, 5.5 cm or 6 cm, etc., which can ensure both a reliable anti-overflow effect and a good user experience of the pot. When h is less than 2 cm, the soup or foam that rises to the lid for discharge can easily overflow the top of the pot body 8 under the influence of factors such as air flow impact or violent boiling, thereby causing problems such as countertop contamination caused by overflow; when h is greater than 6 cm, the lid occupies a large space in the pot body, and the effective cooking space of the pot body 8 is too small, which affects the user experience of the pot.

[0057] Furthermore, the flow area of ​​the exhaust structure is s, the cross-sectional area of ​​the pot mouth is S, and the value range of s / S is 0.002~0.15. For example, the value of s / S can be 0.002, 0.005, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14 or 0.15, etc., which can achieve both reliable anti-overflow effect and good cooking effect. When the value of s / S is less than 0.002, the flow area of ​​the exhaust structure is too small, and the soup or foam passing through the exhaust structure is likely to splash and scald the user, and the soup or foam in the pot that has not been discharged in time is likely to overflow from the top of the pot body, resulting in problems such as countertop pollution caused by overflow; when the value of s / S is greater than 0.15, the flow area of ​​the exhaust structure is too large, and the air pressure in the pot is too low, affecting the cooking and stewing effect, and the soup in the pot decreases rapidly with the discharge of steam, which is prone to problems such as sticking the pot or dry burning.

[0058] Furthermore, the exhaust structure includes a plurality of exhaust holes 4, each exhaust hole 4 is sequentially arranged around the axis of the support ring 1, and the flow area s of the exhaust structure is the sum of the cross-sectional areas of each exhaust hole 4. The plurality of exhaust holes 4 can increase the exhaust area and effectively prevent overflowing of the pot, and can also make the circumference of the pot cover uniformly exhausted, reduce the vibration or shaking caused by the exhaust reaction force, thereby increasing the stability of the pot cover and reducing the exhaust noise of the pot cover.

[0059] Furthermore, the distance between the exhaust hole 4 and the upper surface of the cover body 2 is not greater than 5 mm. For example, the distance between the exhaust hole 4 and the upper surface of the cover body 2 can be 0 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm, etc., to reduce or eliminate the amount of condensed water retained on the upper surface of the cover body 2 and prevent excessive condensed water from remaining on the upper surface of the cover body 2 and spilling on the countertop.

[0060] In one embodiment, the side of the exhaust hole 4 close to the cover body 2 is aligned with the upper surface of the cover body 2, so that the lowest point of the exhaust hole 4 is aligned with the lowest point of the upper surface of the cover body 2, thereby ensuring that the condensed water retained on the upper surface of the cover body 2 can be completely discharged.

[0061] In another embodiment, the distance between the vent hole 4 and the upper surface of the cover body 2 is 2 mm to 5 mm. For example, the distance between the vent hole 4 and the upper surface of the cover body 2 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm, etc. That is to say, there is a continuous annular area of ​​a certain height between the vent hole 4 and the upper surface of the cover body 2, which can not only reduce the amount of condensed water retained on the upper surface of the cover body 2, but also improve the sealing performance of the pot cover in the heat preservation state, and prevent gas from leaking along the gap between the cover body 2 and the support ring 1. When the distance between the vent hole 4 and the upper surface of the cover body 2 is less than 2 mm, the sealing effect between the cover body 2 and the support ring 1 is poor; when the distance between the vent hole 4 and the upper surface of the cover body 2 is greater than 5 mm, more condensed water is retained on the upper surface of the cover head 5.

[0062] Furthermore, a return surface 21 is formed on the upper surface of the cover body 2, and the height of the return surface 21 gradually decreases along the direction away from the axis of the cover body 2. For example, the return surface 21 can be set to an inclined surface or a curved surface, etc., to ensure that the condensed water generated on the surface of the cover body 2 can quickly flow back into the pot body 8, reducing the residual condensed water on the upper surface of the cover body 2, thereby improving the overall cleanliness of the pot cover.

[0063] The pot cover provided in the embodiment of the present application also includes a connector, through which the cover body 2 is connected to the support ring 1, and at least a portion of the connector extends along the axial direction of the support ring 1 to meet the axial movable stroke of the cover body 2. The connector can be set as a circumferentially closed annular structure to increase the strength of the connector itself and prevent the connection between the cover body 2 and the support ring 1 from breaking, and the exhaust structure runs through the side wall of the connector. The connector can be set as a strip structure or a columnar structure, and the number of connectors is not less than three, and each connector is arranged in sequence around the axis of the support ring, and the gap between adjacent connectors forms an exhaust structure.

[0064] The connector can be made of a flexible material such as silicone, and the flexible deformation of the connector can adapt to the axial movement of the cover 2; the connector can also be made of a hard material such as metal, and the cover 2 can slide along the connector to achieve the axial movement of the cover 2. The connector and the support ring 1 can be connected to each other as a whole by non-detachable means such as integral molding, bonding, injection molding, etc., and the connector and the support ring 1 can also be connected and fixed to each other by detachable means such as threaded fitting or snap fasteners.

[0065] Furthermore, the pot cover also includes a flexible sleeve 3, and the flexible sleeve 3 is provided with an exhaust structure, that is, the flexible sleeve 3 is used as the above-mentioned connecting member, and the flexible sleeve 3 is set to a circumferentially closed annular structure, and the flexible sleeve 3 is made of a flexible material. The cover body 2 is connected to the support ring 1 through the flexible sleeve 3. For example, the flexible sleeve 3 and the support ring 1 and the flexible sleeve 3 and the cover body 2 can be connected to each other by bonding or injection molding, which can maintain the integrity of the support ring 1 and the cover body 2, and can retain the original structure of the pot cover to the maximum extent, thereby reducing the production cost of the pot cover. The cover body 2 can switch between the heat preservation state and the exhaust state through the deformation of the flexible sleeve 3. The movement resistance of the cover body 2 is small, which can improve the convenience of the operation of the cover body 2, and the flexible sleeve 3 can play a role in buffering and vibration reduction. The noise during the movement of the cover body 2 is small, thereby improving the use experience of the pot cover.

[0066] Furthermore, when the cover 2 is closed over the opening, the flexible sleeve 3 is folded and sandwiched between the cover 2 and the support ring 1, thereby increasing the stability and reliability of the cooperation between the cover 2 and the support ring 1, and preventing the cover 2 from shaking or accidentally sinking during use. When the cover 2 sinks into the opening, the flexible sleeve 3 is opened and suspended between the cover 2 and the support ring 1, so that the cover 2 is suspended below the support ring 1 through the flexible sleeve 3, so that the cover 2 can float or shake freely with the overflowing soup, preventing the entire pot cover from being lifted up.

[0067] Specifically, the support ring 1 surrounds the outer circumference of the cover body 2, and an annular gap is formed between the support ring 1 and the cover body 2. At least a portion of the flexible sleeve 3 is clamped between the support ring 1 and the cover body 2, thereby reducing the annular gap between the support ring 1 and the cover body 2, achieving the overlapping fit of the cover body 2 and the support ring 1, and the flexible sleeve 3 can be expanded and contracted along the radial direction of the cover body 2, so that the cover body 2 can reciprocate through the support ring 1 under the action of external force, ensuring that the cover body 2 can freely switch between the insulation state and the exhaust state.

[0068] Furthermore, the flexible sleeve 3 includes a first connection portion 35 and a second connection portion 36 that are arranged opposite to each other, the first connection portion 35 is connected to the support ring 1, and the second connection portion 36 is connected to the cover body 2. At least a portion of the first connection portion 35 is attached to the inner ring of the support ring 1, so that the first connection portion 35 provides flexible support to the cover body 2 at the inner ring of the support ring 1. At least a portion of the second connection portion 36 is attached to the outer ring of the cover body 2, so that the outer ring of the cover body 2 is flexibly overlapped with the support ring 1 through the second connection portion 36. When the cover body 2 is overlapped with the support ring 1, the cover body 2 and the support ring 1 are pressed against each other through the first connection portion 35 or the second connection portion 36, so that a flexible support is formed between the cover body 2 and the support ring 1, reducing the mutual collision or wear between the two.

[0069] Furthermore, the flexible sleeve 3 includes an exhaust portion 31, an exhaust structure is arranged on the exhaust portion 31, the exhaust portion 31 is connected to the cover body 2 (for example, the exhaust portion 31 is connected to the cover body 2 via the second connection portion 36), and extends along the axial direction of the cover body 2; when the cover body 2 is switched from the exhaust state to the heat preservation state, the exhaust portion 31 is flipped and folded upward to reduce the volume of the pot cover in the heat preservation state and improve the user experience; when the cover body 2 is switched from the heat preservation state to the exhaust state, the exhaust portion 31 is flipped and opened downward to lower the height of the exhaust portion 31, thereby controlling the liquid level in the pot and preventing the overflowed soup or foam from contacting the support ring 1 and lifting the pot cover as a whole.

[0070] Furthermore, along the direction away from the cover body 2, the radial dimension of at least a section of the exhaust portion 31 gradually increases, that is, the two ends of the exhaust portion 31 are staggered from each other along the radial direction of the cover body 2, so that the cover body 2 can form a flipping torque on the exhaust portion 31, ensuring that the exhaust portion 31 can flip regularly and preventing the exhaust portion 31 from unexpected deformation such as wrinkles.

[0071] Further, the flexible sleeve 3 includes a fixing portion 34, that is, the fixing portion 34 is made of a flexible material, the fixing portion 34 is connected to the support ring 1 (for example, the fixing portion 34 is connected to the support ring 1 through the first connecting portion 35), and is suspended below the support ring 1, and the exhaust portion 31 is located at one end of the fixing portion 34 away from the support ring 1. On the one hand, the fixing portion 34 extends along the axial direction of the support ring 1, and when the exhaust portion 31 is turned over and opened, the exhaust portion 31 is suspended below the fixing portion 34, thereby further reducing the height of the exhaust portion 31 in the turned over and opened state, and further increasing the degree of freedom of the exhaust portion 31, effectively preventing the pot cover from being lifted up as a whole; on the other hand, when the exhaust portion 31 is turned over and folded, the exhaust portion 31 is sleeved on the inner side of the fixing portion 34, thereby forming a double-layer flexible structure, which can not only increase the sealing and heat preservation effect, but also prevent the flexible sleeve 3 from colliding or interfering with the pot edge and other parts, affecting the use experience. Of course, in other embodiments, the fixing portion 34 can also be made of a hard material, for example, the fixing portion 34 is formed by extending downward from the opening.

[0072] Furthermore, a first flip portion 32 is provided between the exhaust portion 31 and the fixed portion 34. The first flip portion 32 may adopt any appropriate structure such as a hinge, a fold, a step or local thinning, which can not only reduce the flipping resistance of the exhaust portion 31 and make the flipping movement of the exhaust portion 31 more labor-saving, but also reduce the stress of the exhaust portion 31 in the folded state, thereby improving the stability of the overlap between the cover body 2 and the support portion.

[0073] Furthermore, a second flip portion 33 is provided between the exhaust portion 31 and the cover body 2, for example, the second flip portion 33 is provided between the exhaust portion 31 and the second connecting portion 36. The second flip portion 33 may adopt any appropriate structure such as a hinge, a fold, a step or a local thinning, which can not only reduce the movement resistance of the cover body 2, making the axial movement of the cover body 2 more labor-saving, but also reduce the rebound force of the exhaust portion 31 on the cover body 2, thereby improving the stability of the overlap between the cover body 2 and the support portion.

[0074] Further, the support ring 1 includes an outer edge 11 and an inner edge 12, and the inner edge 12 is surrounded to form an opening. The height of the inner edge 12 is higher than the height of the outer edge 11 to increase the axial space of the support ring 1, and the flexible sleeve 3 is connected to the inner edge 12. When the cover 2 is overlapped on the support ring 1, the flexible sleeve 3 is completely located above the outer edge 11, that is, the flexible sleeve 3 is folded and stored in the space surrounded by the support ring 1 to avoid the flexible sleeve 3 from contacting with the support table when the pot cover is placed and contaminating; when the cover 2 is suspended below the support ring 1, the edge of the cover 2 is located below the outer edge 11, that is, the cover 2 is suspended within the height range of the pot body 8, so that exhaust and overflow are performed within the height range of the pot body 8, avoiding the liquid level from rising to the top of the pot body 8, and effectively preventing the soup or foam from overflowing along the top of the pot body 8. Of course, in other embodiments, the height of the outer edge 11 and the height of the inner edge 12 can also be substantially the same.

[0075] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
