[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] This embodiment mainly describes the structure of the pot cover bead, which is as follows:

[0026] An adjustable cover bead, such as Figures 1-6As shown, it includes a pot cover 1, a mounting ring 101, a cover bead 2, an extension plate 3, a limit rod 4, a return spring 5, a button 6 and an adjustment component. The pot cover 1 is connected with a mounting ring 101 in the middle, and the mounting ring 101 is rotatably connected to the cover bead 2 in the form of a handle. A plurality of limit rods 4 are connected inside the cover bead 2, and the plurality of limit rods 4 are slidably connected to the extension plate 3. The extension plate 3 is bent as a whole, and a return spring 5 is provided at the bottom of the limit rod 4. One end of the return spring 5 is connected to the bottom of the extension plate 3, and the other end is connected to the cover bead 2. The button 6 is slidably connected to the cover bead 2, and the bottom is connected to one end of the extension plate 3. The other end of the extension plate 3 is connected to the adjustment component. The adjustment component is located in the mounting ring 101 and is used to adjust the ventilation volume of the pot cover 1.

[0027] like Figure 2-Figure 4 As shown, the adjustment assembly includes a lower pressing block 7, a clamping block 8 and an adjustment plate 801. The lower pressing block 7 is connected to the bottom of the extension plate 3 and is located in the mounting ring 101. A clamping slot 9 is provided on the inner side of the mounting ring 101. The lower pressing block 7 is connected to the clamping block 8. The clamping block 8 is slidably connected to the clamping slot 9 and cooperates with the mounting ring 101 to limit the position. The adjustment plate 801 is rotatably connected to the mounting ring 101. A second exhaust hole 803 is provided at the bottom of the mounting ring 101. The second exhaust hole 803 passes through the pot cover 1. A first exhaust hole 802 is provided on the adjustment plate 801, and a third exhaust hole 804 is provided on the cover bead 2. The clamping block 8 is slidably connected to the adjustment plate 801. The clamping block 8 is clamped and cooperated with the adjustment plate 801. The first exhaust hole 802 of the adjustment plate 801 occupies half of its area, and the first exhaust hole 802 and the third exhaust hole 804 are vertically aligned.

[0028] During cooking, put the pot cover 1 on the pot. According to the pressure requirements of the cooking dishes, hold the cover bead 2 and press the button 6. The button 6 drives the extension plate 3 to move downward. The extension plate 3 slides on the limit rod 4 and compresses the return spring 5, pushing the pressing block 7 and the card block 8 to move downward at the same time, so that the card block 8 is inserted into the adjustment plate 801 and disengaged from the card slot 9 of the mounting ring 101. Then rotate the cover bead 2, the pressing block 7, the card block 8 and the adjustment plate 801 all rotate with the cover bead 2. When the adjustment plate 801 rotates, the first The exhaust hole 802 is gradually misaligned with the second exhaust hole 803, thereby reducing the area of ​​the exhaust hole of the pot cover 1 and the exhaust rate. The gas passes through the second exhaust hole 803, the first exhaust hole 802 and the third exhaust hole 804 in turn. Changing the ventilation rate can adjust the pressure in the pot. After adjusting to the appropriate position, release the button 6, the reset spring 5 rebounds, and pushes the extension plate 3 to reset upward. The lower pressing block 7 and the card block 8 slide upward, and the card block 8 leaves the adjustment plate 801 and re-engages with the card slot 9 to limit the position, so that the cover bead 2 cannot be rotated.

[0029] like Figure 5As shown, it also includes a connecting plate 10, a heat insulation plate 11 and an extension plate 12. The side of the cover bead 2 is connected to the connecting plate 10, the bottom of the connecting plate 10 is connected to the heat insulation plate 11, and the extension plate 12 is slidably connected inside the heat insulation plate 11.

[0030] When covering or removing the pot lid 1, the extension plate 12 is pulled out and slides inside the heat insulation plate 11 to shield the outer end of the cover bead 2, thereby preventing hot air from directly contacting the hand bowl or arm, thereby preventing the user from being scalded.

[0031] like Figure 5 As shown, an anti-skid pad 13 is also included, and the top of the button 6 is connected to the anti-skid pad 13.

[0032] The pattern on the surface of the anti-slip pad 13 provides sufficient friction when pressing the button 6, and the pressing can be kept stable during the rotation of the cover bead 2.

[0033] like Figure 6 As shown, it also includes a scale ring 14 and an indicator plate 15 . The scale ring 14 is provided on the top of the mounting ring 101 , and the indicator plate 15 is connected to the cover bead 2 .

[0034] When the cover bead 2 is rotated, the indicator plate 15 also rotates along with the cover bead 2 and points to the scale on the scale ring 14 , which corresponds to the effective exhaust area of ​​the second exhaust hole 803 after adjustment.

[0035] like Figure 3 and Figure 4 As shown, it also includes a ball 17 , which is disposed in the mounting ring 101 and is located between the mounting ring 101 and the cover bead 2 .

[0036] When the cover bead 2 is rotated, the ball 17 changes the sliding friction between the cover bead 2 and the mounting ring 101 into rolling friction, thereby reducing the friction force that needs to be overcome when rotating the cover bead 2 and optimizing the adjustment process.

[0037] like Figure 6 As shown, a support rod 16 is also included, and the end of the cover bead 2 is connected to the support rod 16.

[0038] After removing the pot cover 1, the pot cover 1 can be placed vertically through the edge of the pot cover 1 and the end of the support rod 16, so that the dripping water vapor can be gathered in one place for easy wiping.

[0039] The user holds the cover bead 2 and presses button 6, causing the block 8 to disengage from the slot 9 and insert into the adjustment plate 801. At this point, the cover bead 2 can be rotated, driving the downward pressure block 7, the block 8, and the adjustment plate 801 to rotate synchronously. The first exhaust hole 802 on the adjustment plate 801, the second exhaust hole 803 on the pot lid 1, and the third exhaust hole 804 on the cover bead 2 jointly control the ventilation rate. As the adjustment plate 801 rotates, the misalignment between the first exhaust hole 802 and the second exhaust hole 803 changes, thereby adjusting the exhaust area and rate to meet different cooking needs. After the adjustment is completed, release button 6, the reset spring 5 pushes the extension plate 3 back to its original position, and the block 8 re-engages the slot 9, fixing the position of the cover bead 2. In addition, the design of the connecting plate 10, the heat insulation plate 11 and the extension plate 12 can provide protection when the pot lid 1 is opened and closed to prevent burns from hot steam; the anti-slip pad 13 increases the stability when the button 6 is operated, the scale ring 14 and the indicator plate 15 help the user to accurately adjust the ventilation volume, the ball 17 reduces the rotational friction to make the adjustment smoother, and the support rod 16 facilitates the vertical placement of the pot lid 1 to collect dripping water vapor.
