Description

Technical Field

[0001] The present application relates to the technical field of kitchen utensils, and in particular to a pot cover and a pot. Background Art

[0002] Cookware is the most commonly used daily necessities in life. People cannot live without cookware for cooking rice and soup in their daily life. However, the continuous boiling of soup such as rice soup in the pot will produce a lot of foam and cause the liquid level to rise, thus overflowing the pot, resulting in large-scale stains on the pot or countertop. Therefore, an anti-overflow structure such as an opening is usually provided on the pot cover, but the existing anti-overflow structure has a poor anti-overflow effect. During the cooking process, liquid will still overflow or splash and the pot cover will be lifted up, affecting the user experience of the pot. Utility Model Content

[0003] The present application provides a pot cover and a cookware to improve the anti-overflow effect of the pot cover, thereby improving the user experience of the cookware.

[0004] The first aspect of the present application provides a pot cover, comprising:

[0005] A support ring, wherein an opening is formed on the inner side of the support ring;

[0006] The cover body is movably connected to the support ring and can move along the axial direction of the support ring. The cover body can cover the opening to form a heat-insulating state, and the cover body can sink into the opening to form a venting state.

[0007] The pot cover provided by the present application includes a support ring and a cover body, wherein the support ring is used to cooperate with the pot body, and an opening is formed on the inner side of the support ring; the cover body is movably connected to the support ring and can move along the axial direction of the support ring; the cover body can cover the opening to form a heat preservation state, and the cover body can sink into the opening to form a venting state. Since the cover body sinks into the opening for venting, the upper surface of the cover body is lower than the support ring, so that a reflux space with a certain height is formed above the cover body, and the reflux space is exposed to the outside of the pot body. Even if the soup or foam in the pot overflows, it can be quickly cooled in the reflux space and reflux into the pot, which can effectively avoid problems such as countertop contamination caused by overflowing pots, and can also reflux the liquid with a lower temperature into the pot to cool the soup in the pot, thereby lowering the liquid level in the pot.

[0008] Optionally, the pot cover further includes a flexible sleeve, and the cover body is connected to the support ring through the flexible sleeve; when the cover body covers the opening, the cover body is overlapped on the top of the support ring through the flexible sleeve; when the cover body sinks into the opening, the cover body is suspended below the support ring through the flexible sleeve. The deformation of the flexible sleeve enables the cover body to switch between the heat preservation state and the exhaust state. The movement resistance of the cover body is small, which can improve the convenience of the cover body operation. The flexible sleeve can play a role of buffering and vibration reduction. The noise during the movement of the cover body is small, thereby improving the user experience of the pot cover.

[0009] Optionally, the flexible sleeve includes an exhaust portion, the exhaust portion is connected to the cover body and extends along the axial direction of the cover body;

[0010] When the cover body switches from the exhaust state to the heat preservation state, the cover body drives the exhaust part to flip and fold upwards, so as to reduce the volume of the pot cover in the heat preservation state and improve the user experience;

[0011] When the cover body switches from the heat preservation state to the exhaust state, the cover body drives the exhaust part to flip and open downward to lower the height of the exhaust part, thereby controlling the liquid level in the pot and preventing overflowing soup or foam from contacting the support ring and lifting the entire pot cover.

[0012] Optionally, along the direction away from the cover body, the radial dimension of at least a section of the exhaust portion gradually increases, so that the cover body can form a flipping torque on the exhaust portion, ensuring that the exhaust portion can flip regularly and preventing accidental deformation such as wrinkles on the exhaust portion.

[0013] Optionally, a first flipping portion is provided at one end of the exhaust portion away from the cover body, which can not only reduce the flipping resistance of the exhaust portion, making the flipping movement of the exhaust portion more labor-saving, but also reduce the stress of the exhaust portion in the folded state, thereby improving the stability of the overlap between the cover body and the support portion.

[0014] Optionally, a second flip portion is provided between the exhaust portion and the cover body, which can reduce the movement resistance of the cover body and make the axial movement of the cover body more labor-saving, and can also reduce the rebound force of the exhaust portion on the cover body, thereby improving the stability of the overlap between the cover body and the support portion.

[0015] Optionally, the flexible sleeve includes a fixing portion, the fixing portion is connected to the support ring and suspended below the support ring, and the exhaust portion is located at one end of the fixing portion away from the support ring. On the one hand, the fixing portion extends along the axial direction of the support ring, and when the exhaust portion is flipped open, the exhaust portion is suspended below the fixing portion, thereby further reducing the height of the exhaust portion in the flipped open state, effectively preventing the pot cover from being lifted up as a whole; on the other hand, when the exhaust portion is flipped and folded, the exhaust portion is sleeved on the inner side of the fixing portion, thereby forming a double-layer flexible structure, which can not only increase the sealing and heat preservation effect, but also prevent the flexible sleeve from colliding or interfering with the pot edge and other parts, affecting the user experience.

[0016] Optionally, the support ring comprises an outer edge and an inner edge, the inner edge surrounds and forms the opening, the height of the inner edge is higher than the height of the outer edge, and the flexible sleeve is connected to the inner edge;

[0017] When the lid is overlapped with the support ring, the flexible sleeve is completely located above the outer edge, so that the flexible sleeve is folded and stored in the space surrounded by the support ring, so as to avoid the flexible sleeve from contacting with the support table and the like and causing contamination when the pot lid is placed;

[0018] When the cover body is suspended under the support ring, the edge of the cover body is located below the outer edge, so that the cover body is suspended within the height range of the pot body, thereby venting and overflowing within the height range of the pot body, avoiding the liquid level from rising to the top of the pot body, and effectively preventing soup or foam from overflowing along the top of the pot body.

[0019] Optionally, an exhaust structure is provided below the opening, and the exhaust structure includes a plurality of exhaust holes, and the exhaust holes are arranged in sequence around the axis of the support ring. This can increase the exhaust area and effectively prevent overflowing, and can also make the circumference of the pot cover evenly exhausted, reduce vibration or shaking caused by exhaust reaction force, thereby increasing the stability of the pot cover and reducing the exhaust noise of the pot cover.

[0020] Optionally, the distance between the exhaust hole and the upper surface of the cover body is not greater than 5 mm, so as to reduce or eliminate the amount of condensed water retained on the upper surface of the cover body and prevent excessive condensed water from being retained on the upper surface of the cover body and spilling on the table.

[0021] Optionally, a return surface is formed on the upper surface of the cover body, and the height of the return surface gradually decreases along the direction away from the axis of the cover body, so as to ensure that condensed water generated on the surface of the cover body can quickly flow back into the pot body, reducing the residual condensed water on the upper surface of the cover body, thereby improving the overall cleanliness of the pot cover.

[0022] A second aspect of the present application provides a cookware, comprising a pot body and any one of the pot covers provided in the present application, wherein the support ring cooperates with the pot body.

[0023] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] 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

[0049] 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.

[0050] 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.

[0051] 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.

[0052] like Figure 1-Figure 6As shown, the embodiment of the present application provides a pot cover, which 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, and an opening is formed on the inner side of the support ring 1; the cover body 2 is movably connected to the support ring 1 and can move along the axial direction of the support ring 1. The cover body 2 can cover the opening to form a heat preservation state, that is, the cover body 2 can be close to the support ring 1 to close the opening, thereby increasing the cooking speed; the cover body 2 can sink to the opening to form a venting state, that is, the cover body 2 can be away from the support ring 1 to open the opening, thereby meeting the venting requirements and preventing the soup in the pot from overflowing. In addition, since the cover body 2 sinks into the opening, 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. 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. 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 the soup in the pot, thereby lowering the liquid level in the pot.

[0053] Specifically, an exhaust structure (e.g., exhaust hole 4, exhaust gap or exhaust channel, etc.) may be provided below the opening. When the cover 2 is located above the exhaust structure, the cover 2 closes the opening to form a heat preservation state; when the cover 2 is located below the exhaust structure, the exhaust structure connects the inside and outside of the cover 2, so that the cover 2 forms an exhaust state.

[0054] Furthermore, the exhaust structure includes a plurality of exhaust holes 4, and each exhaust hole 4 is sequentially arranged around the axis of the support ring 1. This can increase the exhaust area and effectively prevent overflowing, and can also make the circumference of the pot cover evenly 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Furthermore, 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 respectively press against the two ends of the support sleeve 7. 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 lifted. There is no need to change the original structure of the cover head 5 and the cover body 2. Only the length of fasteners such as screws 6 needs to be increased. It is easy to implement and the production cost is low.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Furthermore, when the cover 2 is closed over the opening, the cover 2 is overlapped on the top of the support ring 1 through the flexible sleeve 3, thereby providing a reliable axial support force for the cover 2 to prevent the cover 2 from accidentally sinking. Of course, the cover 2 can also be embedded in the support ring 1, or abutted against the bottom of the support, as long as the opening can be closed. When the cover 2 sinks into the opening, 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.

[0065] 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.

[0066] 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.

[0067] 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 a 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 insulation state, the exhaust portion 31 is flipped and folded upward to reduce the volume of the pot cover in the insulation state and improve the user experience; when the cover body 2 is switched from the insulation 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.

[0068] 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.

[0069] Furthermore, a first flip portion 32 is provided at one end of the exhaust portion 31 away from the cover body 2. The first flip portion 32 can 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.

[0070] 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.

[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, and the exhaust portion 31 and the fixing portion 34 can be connected to each other through the first flip portion 32. 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 flipped open, the exhaust portion 31 is suspended below the fixing portion 34, thereby further reducing the height of the exhaust portion 31 in the flip open state, effectively preventing the pot cover from being lifted up as a whole; on the other hand, when the exhaust portion 31 is flipped 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 each other and 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] 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.

[0073] In addition, an embodiment of the present application further provides a cookware, which includes a pot body 8 and any one of the pot covers provided in the embodiment of the present application, wherein the support ring 1 cooperates with the pot body 8 so that the pot cover is covered on the pot body 8 .

[0074] 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.
