[0092] The present application provides a detachable cover assembly, a cover body and a cooking utensil.

[0093] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0094] like Figure 1 and Figure 2 As shown, the cooking utensil 100 according to a specific embodiment of the present application mainly includes a lid 10 and a pot body 90. The pot body 90 is generally in the shape of a rectangular parallelepiped with rounded corners and has a cylindrical cooking container storage portion. A cooking container 91 can be freely placed in or removed from the cooking container storage portion, making it easy to clean the cooking container 91. The top of the cooking container 91 has a circular opening for placing ingredients to be heated, such as rice, soup, etc., into the cooking container 91. The opening of the cooking container 91 is provided with a radially outwardly curved edge 92. The lid 10 is generally in the shape of a rectangular parallelepiped with rounded corners and substantially corresponds to the shape of the pot body 90. The lid 10 is pivotally connected to the pot body 90 in an openable and closable manner to cover the pot body 90. When the lid 10 is closed on the pot body 90, a cooking space is formed between the lid 10 and the cooking container 91.

[0095] The cover 10 includes a lining cover 11 and a detachable cover assembly 30, which is detachably connected to the lining cover 11. One side of the lining cover 11 along the length direction is a connection end that is pivotally connected to the pot body 90, and the other side is a pivot end for opening and closing the cover. Figure 3As shown, the removable cover assembly 30 has a center and has a central axis L2 passing through the center.

[0096] like Figure 2 and Figure 3 As shown, the detachable cover assembly 30 includes a cover plate 31 and a sealing ring assembly 39. The sealing ring assembly 39 is mounted on the cover plate 31 for sealing between the cover body 10 and the cooking container 91.

[0097] like Figures 4 to 6 As shown, the cover plate 31 is formed with a rolled cavity 34 at its edge. For example, in a cross section passing through the central axis L2, the edge portion 33 of the cover plate 31 forms the rolled cavity 34. The rolled cavity 34 has an opening for installing the sealing ring assembly 39. The cover plate 31 includes a central portion 32 and an edge portion 33. The edge portion 33 is connected to the central portion 32 and is located on the periphery of the central portion 32. The edge portion 33 is provided with a rolled cavity portion 33A with an opening. The rolled cavity portion 33A constitutes at least a portion of the cavity wall of the rolled cavity 34. The outer peripheral side of the rolled cavity portion 33A is used to connect to the liner cover 11.

[0098] It should be noted that “up” and “down” in the present application refer to the directions corresponding to the state in which the cooking utensil 100 is placed normally and the lid 10 is covered on the pot body 90 .

[0099] like Figures 4 to 7 As shown, the sealing ring assembly 39 includes a sealing ring 50 and a metal wire 55. The lower end of the sealing ring 50 protrudes downward from the lowest point of the lower surface of the cover plate 31. When the lid 10 covers the pot body 90, the lower end of the sealing ring 50 contacts the opening of the cooking container 91, for example, the upper surface of the radially outward flared edge 92, to seal between the lid 10 and the cooking container 91. The width of the radially outward flared edge 92 is, for example, 5-25 mm, for example, 10 mm.

[0100] The sealing ring 50 includes a rolled portion 51 and a sealing portion 52. In the assembled state of the sealing ring 50 and the cover plate 31, the rolled portion 51 is accommodated in the rolled cavity 34 to install the sealing ring 50 to the cover plate 31. In the cross section passing through the central axis L2, the rolled portion 51 is curved, for example, it can be a C-shaped bend, a U-shaped bend, a J-shaped bend, etc. The sealing portion 52 is exposed outside the rolled cavity 34, the upper end of the sealing portion 52 is connected to the rolled portion 51 and extends outward to the outside of the rolled cavity 34, and the lower end of the sealing portion 52 is used to contact the radially outward edge 92 at the opening of the cooking container 91. The curved portion of the rolled portion 51 forms a groove 51C (see Figure 7), the bottom 51E of the groove 51C is further away from the opening of the curling cavity 34 than the notch 51D of the groove 51C. The metal wire 55 is accommodated in the groove 51C formed by the bending of the curling portion 51, exerting a radially outward force on the curling portion 51, that is, squeezing the curling portion 51 toward the inner wall of the curling cavity 34, thereby supporting the curling portion 51 within the curling cavity 34 and making the curling portion 51 more securely installed in the curling cavity 34.

[0101] According to the detachable cover assembly 30 of the present application, by installing the rolled portion 51 of the sealing ring 50 into the rolled cavity 34 of the cover plate 31, and accommodating the metal wire 55 in the groove 51C formed by bending the rolled portion 51, the sealing ring 50 is installed firmly, simply and beautifully.

[0102] It should be noted that the metal wire 55 can be partially accommodated in the groove 51C formed by the bend of the rounded portion 51. For example, the metal wire 55 can extend along three-quarters of the circumference of the groove 51C; alternatively, multiple sections of the metal wire 55 can be accommodated at different circumferential positions of the groove 51C. Preferably, the metal wire 55 extends along the groove 51C for a full circle to reinforce the entire rounded portion 51.

[0103] The sealing ring 50 has a radially symmetrical structure, for example, the shape of the cross section remains unchanged. Figure 5 and Figure 7 As shown, the curled portion 51 comprises a first portion 51A and a second portion 51B. In a cross-section through the central axis L2, the first portion 51A is configured to bend about a curling axis, resulting in at least a portion of the inner wall of the groove 51C of the curled portion 51 forming an arc shape. The second portion 51B and the sealing portion 52 are connected to the ends of the first portion 51A. The second portion 51B extends from the end of the first portion 51A and is accommodated within the curled cavity 34 along the inner wall thereof. This allows the curled portion 51 to occupy a majority of the space within the curled cavity 34, providing greater stability within the cavity 34.

[0104] Preferably, in a cross section through the central axis L2, the circumferential angle of the first portion 51A is greater than or equal to 180 degrees, meaning it extends at least halfway around the curling axis. This allows the first portion 51A to contact the outer surface of the wire 55 over at least half its circumference. Consequently, the curled portion 51 occupies most of the space within the curling cavity 34 and has a large contact area with the wire 55. The wire 55 supports the curled portion 51 over a wider angular range, further stabilizing the sealing ring 50. The first portion 51A is located substantially at the deepest point of the curling cavity 34.

[0105] Preferably, the outer side of the curled portion 51 is provided with an inverted tooth 53, which is used to increase the resistance of the curled portion 51 when moving toward the opening of the curled cavity 34, so that the installation of the sealing ring 50 is more secure and not easy to fall off. Figure 5As shown, the direction from the root of the inverted tooth 53 to the tip of the inverted tooth 53 is a first direction D1, and the direction from the inside of the curling cavity 34 to the outside of the curling cavity 34 along the axis of the opening of the curling cavity 34 is a second direction D2. The angle between the first direction D1 and the second direction D2 is an acute angle. Therefore, when the curling portion 51 tends to move outward from the curling cavity 34, the inverted teeth 53 can hinder the outward movement of the curling portion 51, preventing the sealing ring 50 from falling out of the curling cavity 34. The inverted teeth 53 can be located at least in the portion of the curling portion 51 where friction with the inner wall of the curling cavity 34 occurs during outward movement.

[0106] Optionally, a corner 54 is formed on the outside of the rounded portion 51 in a cross section passing through the central axis L2. The corner 54 is formed, for example, in the curved first portion 51A. When installing the sealing ring 50, the rounded portion 51 is inserted into the rounded cavity 34 starting from the corner 54, making it easier to install the rounded portion 51 in the rounded cavity 34.

[0107] Preferably, in a cross section through the central axis L2, the outer surface of at least one side of the corner portion 54 includes a straight line. Figure 5 As shown, the outer surface of the upper side of the corner portion 54 includes a straight line. More preferably, as Figure 6 As shown, the outer surfaces of both sides of the corner portion 54 are straight lines. That is, in a cross section through the central axis L2, the upper and lower sides of the corner portion 54 are both straight lines. This reduces resistance when the curled portion 51 is inserted into the curling cavity 34, making installation easier.

[0108] Preferably, one end of the curled portion 51 is connected to the outer side of the upper end of the sealing portion 52, and a portion of the curled portion 51 is lower than the upper surface of the sealing portion 52. That is, a portion of the curled portion 51 is lower than the opening of the curled cavity 34, so that the curled portion 51 is more firmly in the curled cavity 34 and is not easy to fall off.

[0109] like Figures 4 to 6 As shown, the rolled cavity portion 33A can be bent at least downward and then inward relative to the central portion 32, thereby forming a rolled cavity 34 together with the central portion 32. There is a gap between the end edge 35 of the rolled cavity portion 33A and the central portion 32, forming an opening of the rolled cavity 34.

[0110] Optionally, the curled cavity portion 33A may bend downward, inward, and then upward relative to the central portion 32. That is, the curled cavity portion 33A extends past the lowest position 36 of the curled cavity 34 and then continues to bend upward.

[0111] Optionally, in a cross section passing through the central axis L2, the rolled cavity portion 33A is bent into an arc shape around a curling axis, and an opening is formed between the end edge 35 of the arc and the central portion 32. Preferably, in a cross section passing through the central axis L2, the rolled cavity portion 33A is bent downward and then inward into an arc shape. For the arc-shaped rolled cavity portion 33A, its curling axis passes through the center of the cross section of the rolled cavity portion 33A. Optionally, the rolled cavity portion 33A forms an arc shape with an outer diameter of 3mm to 15mm. Preferably, the rolled cavity portion 33A forms an arc shape with an outer diameter of 6mm to 15mm. However, the rolled cavity portion 33A in the present application is not limited to an arc shape, and can also be a C-shaped curve of other shapes. Preferably, in the assembled state of the sealing ring 50 and the cover plate 31, the curling axis of the first part 51A of the rolled portion 51 coincides with the curling axis of the rolled cavity portion 33A to form the same curling axis L.

[0112] Furthermore, the arc has a lowest position 36, the end edge 35 of the arc is higher than the lowest position 36 of the arc, and the central angle θ corresponding to the circumferential distance between the end edge 35 of the arc and the lowest position 36 of the arc is less than or equal to 50°. Preferably, the central angle θ corresponding to the circumferential distance between the end edge 35 of the arc and the lowest position 36 of the arc is greater than or equal to 30° and less than or equal to 40°. That is, after the curling cavity portion 33A bends below the curling axis L (i.e., the lowest position 36), it has a portion that continues to extend upward and inward. Therefore, the opening of the curling cavity 34 is higher than the bottom of the curling cavity 34, and the opening size of the curling cavity 34 is appropriate, which can prevent the curling portion 51 from falling off from the curling cavity 34, making the connection between the sealing ring 50 and the cover plate 31 more secure.

[0113] Optionally, the central portion 32 includes an annular first region 32A that extends upward. The curled cavity portion 33A curves at least downward and then inward relative to the first region 32A. A gap is defined between the distal edge 35 of the curled cavity portion 33A and the first region 32A, thereby forming the opening of the curled cavity 34. The first region 32A constitutes a portion of the cavity wall of the curled cavity 34. It should be noted that, in a cross-section passing through the central axis L2, the upward extension of the first region 32A can be a straight line or a curved line. For example, in a cross-section passing through the central axis L2, the first region 32A and the curled cavity portion 33A are connected and form an arc of the same circle.

[0114] Further, if Figure 5 As shown, the edge portion 33 further includes a second region 33B. The second region 33B is located between the rolled cavity portion 33A and the first region 32A. The second region 33B is configured to extend along a plane.

[0115] According to the removable cover assembly 30 of the present application, the opening of the rolled cavity 34 is appropriately sized, making the sealing ring 50 less likely to fall off, with only the sealing portion 52 leaking out. This creates a simple, aesthetically pleasing design that is less susceptible to dirt and grime. By accommodating the wire 55 within the groove 51C formed by the curved rolled portion 51, the sealing ring 50 is more securely mounted. The large contact area between the wall of the rolled cavity 34 and the sealing ring 50 provides a better anti-falloff effect. Furthermore, the relative height of the rolled cavity 34 and the main body of the cover plate 31 can be adjusted, ensuring that the lowest point of the rolled cavity 34 does not protrude excessively from the main body of the cover plate 31.

[0116] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art in the art of this application.
