[0023] It should be noted that: similar reference numerals represent similar items in the following drawings, so once an item is defined in one drawing, it can no longer be further defined and explained in the subsequent drawings.

[0024] This embodiment mainly describes the structure of the cover bead, and specifically as follows:

[0025] A cover bead convenient to disassemble and clean, as Figures 1-4 shown, comprising a pot cover 1, a cover bead 2, an operating rod 3, a knob 31, a gear 4 and a rack 5, the pot cover 1 is provided with a through hole in the middle, the cover bead 2 is slidingly connected in the through hole, the through hole is provided with a matching cavity 101 at the bottom, the operating rod 3 is rotatably connected in the cover bead 2, the knob 31 is connected at the top of the operating rod 3, the gear 4 is connected at the bottom of the operating rod 3, the rack 5 is slidingly connected at the bottom of the cover bead 2, the two racks 5 are provided with protruding rods on the side surfaces for smooth sliding, the rack 5 is engaged with the gear 4, the number of teeth of the rack 5 is equal to that of the gear 4, so that one rotation of the gear 4 can ensure that the rack 5 is completely extended or retracted, the rack 5 is inserted into the matching cavity 101, the matching cavity 101 in the pot cover 1 is cylindrical, the rack 5 can be inserted into the pot cover 1 from any angle, and the matching cavity 101 can cooperate with the insertion of the rack 5, the bottom of the cover bead 2 is closed and provided with a track for the sliding of the rack 5.

[0026] When the user needs to clean the pot cover 1, rotate the knob 31, the knob 31 drives the operating rod 3 to rotate, thereby driving the gear 4 to rotate, the gear 4 is engaged with the rack 5, and the two racks 5 slide in the matching cavity 101, gradually away from the matching cavity 101, and enter the cover bead 2, the slide rail in the cover bead 2 is used for limiting the direction of movement of the rack 5, thereby ensuring that the rack 5 is stably engaged with the gear 4, when the rack 5 is completely separated from the matching cavity 101, the cover bead 2 is held, all the parts in the cover bead 2 are taken out together, since the bottom is covered and closed, the oil fume entering the middle through hole of the pot cover 1 and the matching cavity 101 is less, after the cover bead 2 is taken off, the pot cover 1 is inverted, the pot cover 1 will not tilt and rotate, cleaning is facilitated, the disassembly process of the cover bead 2 is simple, after cleaning is completed, the cover bead 2 is inserted into the pot cover 1, the knob 31 is reversely rotated, the gear 4 is reversely rotated, and the rack 5 engaged with the gear 4 slides to the two sides and is reinserted into the matching cavity 101, and the cover bead 2 is fixed through extrusion matching.

[0027] As shown in Figure 3 , further comprising a fastening rubber pad 11, the rack 5 is connected with the matching cavity 101, the top of the rack 5 is connected with the fastening rubber pad 11, the fastening rubber pad 11 is in contact with the pot cover 1, and the end of the fastening rubber pad 11 away from the rack 5 is thinner, and the end close to the rack 5 is thicker.

[0028] When the rack 5 is inserted into the matching cavity 101, the fastening rubber pad 11 is in an inclined state as a whole, the fastening rubber pad 11 is continuously extruded from thin to thick when the rack 5 is gradually extruded by the pot cover 1, so that an obvious resistance can be felt, and the fastening rubber pad 11 with a certain elasticity can optimize the pressure between the pot cover 1 and the rack 5, so that the installation of the cover bead 2 is more stable.

[0029] As shown in Figure 5 , further comprising a protective cover 6, a clamping block 7 and a limiting plate 8, the cover bead 2 is connected with the limiting plate 8, the protective cover 6 is connected with the clamping block 7 at both ends, the clamping block 7 is limitedly matched with the limiting plate 8, the limiting plate 8 is located on both sides of the knob 31, and the protective cover 6 covers the knob 31.

[0030] The protective cover 6 is designed to cover the knob 31, protect the surface of the knob 31 from oil stains, ensure that the knob 31 is more stable when being twisted, avoid the influence of oil stains on the rotation process of the knob 31, and also do not need to clean the knob 31. If the protective cover 6 is contaminated with oil stains, it can be directly cleaned, and the cleaning liquid will not penetrate into the inside of the cover bead 2 to corrode the gear 4 and the rack 5. When the protective cover 6 needs to be removed, the clamping block 7 is separated from the limiting plate 8 by rotating the protective cover 6, so that the protective cover 6 can be easily removed.

[0031] As shown in Figure 5 , further comprising an auxiliary block 9, the protective cover 6 is connected with the auxiliary block 9, and the auxiliary block 9 is used for rotating the protective cover 6.

[0032] Through the auxiliary block 9, it is more convenient to rotate the protective cover 6, and a better force point is provided.

[0033] As shown in Figure 2 It also includes a sealing ring 10, and the part of the cover bead 2 extending into the pot cover 1 is connected with the sealing ring 10, which is used to fill the gap between the cover bead 2 and the pot cover 1.

[0034] Through the sealing ring 10 sleeved on the cover bead 2, not only the connection between the cover bead 2 and the pot cover 1 is stabilized, but also the air tightness of the pot cover 1 is optimized.

[0035] As shown in Figure 1 It also includes a protrusion 12, and the cover bead 2 is connected with the protrusion 12, which is used to increase the friction force when the user holds the cover bead 2.

[0036] When the cover bead 2 is removed, the protrusion 12 on the cover bead 2 can increase the friction force when the user holds it, which is convenient for better removing the cover bead 2.

[0037] As shown in Figure 1 It also includes an identification card 13, and four identification cards 13 are arranged on the pot cover 1, which are located on the middle through hole of the pot cover 1 and are evenly distributed around.

[0038] Since the number of teeth of the gear 4 is equal to the number of teeth of the rack 5, the initial position of insertion can be confirmed through the identification card 13 after inserting the cover bead 2 each time. In the process of rotating the knob 31, if resistance is encountered but the rotation angle does not reach 360 degrees, the user needs to continue to rotate the knob 31 to avoid misjudging that the rack 5 has been completely inserted into the pot cover 1 due to resistance caused by other factors, thereby affecting the safety of subsequent use.

[0039] The user rotates the knob 31 to drive the operation rod 3 and the gear 4 at the bottom thereof to rotate, the gear 4 meshes with the rack 5 which is slidingly connected to the bottom of the cover bead 2, and drives the rack 5 to slide in the matching cavity 101 and gradually exit, in this process, the fastening rubber pad 11 provides gradually increasing resistance due to its elasticity and thickness change, which not only ensures stable installation, but also optimizes pressure distribution. After the rack 5 completely separates from the matching cavity 101, the cover bead 2 and its internal components can be easily taken out as a whole, which is convenient for cleaning. The protective cover 6 is fixed on the cover bead 2 through the cooperation of the clamping block 7 and the limiting plate 8, which protects the knob 31 from oil pollution, and the auxiliary block 9 facilitates the rotation operation of the protective cover 6. The sealing ring 10 not only enhances the connection stability between the cover bead 2 and the pot cover 1, but also optimizes the air tightness of the pot cover 1. The existence of the identification card 13 enables the user to quickly locate the initial position when reinstalling the cover bead 2, and confirms whether the rack 5 is completely inserted into the matching cavity 101 by observing whether the knob 31 rotates to the preset angle, such as 360 degrees, to ensure the safety and sealing effect of use.
