[0002] In conventional kitchen cookware, in order to prevent liquid from overflowing due to excessive air pressure inside the cookware during cooking, a vent structure is generally added to the cooker lid to regulate the pressure inside the cooker and release steam.

[0003] However, existing pot lid venting structures typically only offer a simple opening and closing function, without the ability to precisely adjust the exhaust volume. When the food is still uncooked, the vent holes connect to the outside world, leading to heat loss. This results in a longer heating time than with a pot without vents, resulting in a significant waste of heating energy. Furthermore, the food's prolonged contact with air leads to more severe oxidation, which, from a health perspective, limits cooking efficiency. Therefore, the present invention provides a valve structure for adjusting the venting state of a pot lid. Utility Model Content

[0031] like Figures 1 to 8 As shown, a valve structure for adjusting the exhaust state of a pot cover is installed on a cover body 1 having an exhaust hole 101, and is used to adjust the exhaust state of the exhaust hole 101. The valve structure includes a flow limiting member 2, an air baffle 3 and a drive assembly; the flow limiting member 2 is fixed on the cover body 1, and the flow limiting member 2 is provided with an air vent 201, the air vent 201 is connected with the exhaust hole 101, and the calibers of the air vent 201 on the left and right sides are different; the air baffle 3 covers the air vent 201 to close the exhaust hole 101; the air baffle 3 rotates relative to the flow limiting member 2, and the drive assembly is used to drive the air baffle 3 to rotate left and right to adjust the exposed area of ​​the air vent 201.

[0032] As an example, the air valve structure of the embodiment of the present application is installed on a cover body 1 having an exhaust hole 101, and is used to adjust the exhaust state of the exhaust hole 101, and realize the switching of three states: no exhaust, large-volume exhaust, and small-volume exhaust. The air valve structure includes a flow limiting member 2, an air blocking member 3, and a drive assembly. The flow limiting member 2 is fixed on the cover body 1 and is provided with an air vent 201. The air vent 201 is connected with the exhaust hole 101, so that the gas in the pot lid can be discharged to the outside through the exhaust hole 101 and the air vent 201. Among them, the left and right sides of the air vent 201 have different diameters, that is, the cross-sectional area of ​​the left part of the air vent 201 is different from the cross-sectional area of ​​the right part; utilizing this feature of the air vent 201, by covering the left or right side of the air vent 201 and exposing the other side for exhaust, the exhaust volume of the air vent 101 can be adjusted to achieve different exhaust effects. At the same time, before adjustment, the air stopper 3 is in a position completely covering the vent hole 201, closing the exhaust hole 101. Furthermore, to allow the left or right side of the vent hole 201 to be exposed for exhaust, the air stopper 3 is configured to rotate relative to the flow restrictor 2. The drive assembly drives the air stopper 3 to rotate left or right, thereby adjusting the exposure of the left or right side of the vent hole 201, changing the exposed area of ​​the vent hole 201, and thus adjusting the exhaust volume.

[0033] The air valve structure of this embodiment has the advantages of simple structure, easy operation, and flexible adjustment. Through this air valve structure, the exhaust state of the exhaust holes on the pot cover can be easily adjusted, so that the pot cover can have the advantages of both a pot cover with air holes and a pot cover without air holes. It can be adjusted according to the usage scenario to meet different cooking needs; minimize the time that food is in contact with air and maintain the oxygen content of the food; and can significantly improve the cooking effect and user experience.

[0034] In one embodiment, the flow limiting member 2 is provided with an axial hole 202, and the air blocking member 3 is provided with a rotating shaft 31, which is rotatably connected to the axial hole 202; one end of the air blocking member 3 covers the vent hole 201, and the other end is connected to the driving component.

[0035] As an example, see Figure 3 、 Figure 4 、 Figure 7 and Figure 8 The flow restrictor 2 has an axial hole 202, and the air baffle 3 has a rotating shaft 31. The rotating shaft 31 is rotatably connected to the axial hole 202, allowing the air baffle 3 to rotate smoothly relative to the flow restrictor 2. One end of the air baffle 3 covers the vent 201, and the other end is connected to the drive assembly. The drive assembly drives the air baffle 3 to rotate about the rotating shaft 31, and the air baffle 3 is adjusted to expose the left or right side of the vent 201 for exhaust.

[0036] In one embodiment, the driving assembly includes a fixing member 4 and an adjusting member 5; the fixing member 4 is fixedly connected to the cover body 1; the adjusting member 5 rotates relative to the fixing member 4 to achieve flipping; the adjusting member 5 is provided with a slot 501 along the axial direction of its flipping, and the air-blocking member 3 is provided with a raised hemisphere 32, which is engaged in the slot 501; when the adjusting member 5 flips, it drives the air-blocking member 3 to rotate.

[0037] As an example, see Figures 1 to 6 The driving assembly includes a fixing member 4 and an adjusting member 5. The fixing member 4 is fixedly connected to the cover body 1, and the adjusting member 5 rotates relative to the fixing member 4 to achieve flipping. The adjusting member 5 is provided with a slot 501 along the axial direction of its flipping, and a raised hemispherical body 32 is provided on the air baffle 3. The hemispherical body 32 is engaged in the slot 501 and can rotate within the slot 501. When the adjusting member 5 flips, the cooperation between the slot 501 and the hemispherical body 32 drives the air baffle 3 to rotate, thereby adjusting the exposed area of ​​the vent 201 and further adjusting the exhaust volume.

[0038] In one embodiment, a pin 41 is provided on the fixing member 4, and a connecting hole 502 is provided at the center of the adjusting member 5. The pin 41 is passed through the connecting hole 502 to realize the flipping of the adjusting member 5; the card slot 501 is provided along the extension direction of the connecting hole 502.

[0039] As an example, see Figure 3 、 Figure 5 and Figure 6 The fixing member 4 is provided with a pin 41 along the horizontal direction. The adjusting member 5 is provided with a connecting hole 502 at its center. The pin 41 is inserted into the connecting hole 502 to enable the adjusting member 5 to flip up and down. The engaging slot 501 is provided on the bottom side of the adjusting member 5 along the extension direction of the connecting hole 502, that is, along the axis of the adjusting member 5. When the adjusting member 5 flips up and down, the engaging slot 501 is driven to rotate. The engaging slot 501 and the hemispherical body 32 cooperate to smoothly drive the air blocker 3 to rotate.

[0040] In one embodiment, the fixing member 4 is further provided with a plurality of limiting holes 401, the adjusting member 5 is provided with a slide groove 503, a spring 51 and a spherical limiting block 52 are provided in the slide groove 503, and the two ends of the spring 51 are in contact with the adjusting member 5 and the spherical limiting block 52 respectively. The pre-tightening force of the spring 51 drives the spherical limiting block 52 to extend out of the slide groove 503 and engage in the limiting hole 401.

[0041] As an example, see Figure 5 and Figure 6To ensure stable adjustment, the fixing member 4 is further provided with three limiting holes 401: a first limiting hole 401 arranged along the axis of the adjustment member 5's rotation, and a second limiting hole 401 and a third limiting hole 401, located to the left and right of the first limiting hole 401. The adjustment member 5 is provided with a chute 503, in which a spring 51 and a spherical limiting block 52 are disposed. The ends of the spring 51 contact the adjustment member 5 and the spherical limiting block 52, respectively. The preload force of the spring 51 drives the spherical limiting block 52 out of the chute 503 and into engagement with the limiting hole 401, thereby limiting the rotation angle of the adjustment member 5 and maintaining its adjusted position, thus ensuring stable exhaust conditions. When the exhaust state needs to be adjusted again, the adjusting part 5 is pressed to drive it to flip. Since the outer surface of the spherical limit block 52 is a spherical structure, the spherical limit block 52 can withdraw from the original limit hole 401 after being subjected to force, and be engaged in another limit hole 401 as the adjusting part 5 flips, thereby realizing the switching of the exhaust state and maintaining stability.

[0042] In one embodiment, a gasket 6 is further provided between the flow limiting member 2 and the cover body 1 .

[0043] As an example, see Figure 3 and Figure 4 In order to ensure the close fit between the valve structure and the cover body 1, a silicone pad 421 is provided between the flow limiting member 2 and the cover body 1 to prevent the valve structure from loosening.

[0044] In one embodiment, a handle 42 is provided on the fixing member 4 , and the exhaust hole 101 is provided at one end of the handle 42 .

[0045] As an example, see Figure 3 and Figure 6 In order to facilitate the user to take the pot cover, a handle 42 is provided on the fixing member 4; and the exhaust hole 101 is provided at one end of the handle 42 to prevent the steam discharged from the exhaust hole 101 from directly rushing to the user's hand to prevent burns.

[0046] In one embodiment, the handle 42 is configured as an arc-shaped structure with a concave center, and a rubber pad 421 is provided in the concave portion of the handle 42 .

[0047] As an example, see Figure 3 and Figure 6 The handle 42 is configured as an arc-shaped structure with a concave middle portion, which allows the user to place the spatula or spoon on top of the fixing member 4 during cooking. A rubber pad 421 is provided in the concave portion of the handle 42 to prevent the spatula or spoon from rolling and falling, thereby effectively preventing the spatula or spoon from getting dirty.

[0048] Regarding the embodiments of the present invention, it should also be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other to obtain new embodiments.
