[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0037] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items

[0039] As Figures 1 to 8 shown, in an embodiment of the present invention, a detachable top-bead pot lid is disclosed, which includes a pot lid 1 and a top bead 2 located at the upper end of the pot lid 1. A connecting head 11 is provided on the pot lid 1, and the top bead 2 is detachably connected to the connecting head 11. This is used to avoid the top bead from being hot when lifting and placing the pot lid, especially in some steaming and baking cooking steps

[0040] Among them, a locking groove 111 is formed by circumferentially concave on the outer side of the connecting head 11. A locking member 22 is movably arranged on the top bead 2, and a button 21 for driving the locking member 22 to move. After being driven, the button 21 restricts the position of the locking member 22, so that the locking member 22 enters the locking groove 111 for locking, or the locking member 22 leaves the locking groove 111 for unlocking, thereby forming a locked state of mutual connection and an unlocked state of mutual separation between the top bead 2 and the connecting head 11

[0041] Furthermore, the top bead 2 is sleeved outside the connector 11 and connected to the outer peripheral wall of the connector 11. The top bead 2 includes a housing 23 and an inner housing 24.

[0042] To effectively connect to the connector 11, an installation space 231 penetrating through the upper and lower ends is provided inside the housing 23. The installation space 231 is used to accommodate the inner housing 24 and the button 21. Among them, the lower end of the inner housing 24 is provided with a receiving cavity 241 adapted to the connector 11, which can be sleeved outside the connector 11. And a plurality of through-type movable holes 3 for accommodating the locking member 22 are provided on the circumferential side wall of the receiving cavity 241, through which the locking member 22 passes and acts on the locking groove 111 on the outer periphery of the connector 11, thereby forming the above locking state.

[0043] Furthermore, the button 21 is movably connected in the installation space 231, forming a sliding connection state of moving up and down along the installation space 231. And a part of the button 21 passes through one end of the movable hole 3 far from the receiving cavity 241 during the up and down sliding process and contacts the locking member 22, thereby controlling the locking member 22 to move in the direction close to the connector 11 or away from the connector 11. That is, the relative position of the locking member 22 and the locking groove 111 is restricted.

[0044] It should be explained that for the above descriptions of "upper end", "lower end" and the up and down directions in the following text, "up" can be understood as the direction away from the connector 11, and "down" can be understood as the direction tending to the connector 11.

[0045] As mentioned above, the connector 11 and the pot lid 1 can be integral or connected by a connecting member (screw).

[0046] Such as Figure 1 And Figure 4 As shown in, the shape of the pot lid 1 can be a flat lid or an arched lid. However, it does not affect the connection between the connector 11 and the pot lid 1.

[0047] To make the structure of the button 21 on the top bead 2 driving the locking member simple and effective, in an embodiment, the installation space 231 forms an upper space and a lower space opposite to each other. The inner housing 24 is connected in the lower space, and the outer periphery of the inner housing 24 is partially connected to the inner wall of the installation space 231, and the remaining part is spaced to form a locking member driving area 4 for part of the button 21 to pass through. The button 21 is slidably connected in the upper space and has a moving direction of moving up and down along the installation space 231. The button 21 is provided with a movable column 211 that partially extends into the locking member driving area 4 to cooperate with the locking member 22.

[0048] The movable hole 3 for accommodating the locking member 22 has one end communicating with the above-mentioned locking member driving area 4. The locking member driving area 4 plays a role in guiding the button 21 and also provides a movement space for the locking member 22 in the movement direction away from the locking groove 111, so that the locking member 22 can fully move away from the locking groove 111 to complete unlocking.

[0049] Specifically, the locking member driving area 4 plays a role in guiding and limiting the movable column 211. Especially when the inner side of the movable column 211 contacts the locking member 22, the inner wall of the outer shell 23 acts on the outer side of the movable column 211 to prevent the movable column 211 from bending and deforming.

[0050] For example, in the following usage scenario: When the pot lid is lifted with the top bead 2 and the connector 11 in the locked state, at this time the locking groove 111 will push the locking member 22 to move outward. If the movable column 211 bends and deforms outward, it will cause the locking member 22 to leave the locking groove 111, the top bead 2 and the connector 11 will be unlocked, and the pot lid will fall off.

[0051] Reference Figure 2 And Figure 3 , in an embodiment of the present invention, the locking member 22 is a spherical ball. It should be noted that the diameter of the ball needs to be greater than the length of the movable hole 3 so that the movable column 211 can drive the ball to move along the movable hole 3 on one side of the movable hole 3. And, to prevent the ball from falling off from the side of the movable hole 3 close to the accommodating cavity 241, the aperture of the movable hole 3 on the side close to the accommodating cavity 241 is smaller than the diameter of the ball.

[0052] Furthermore, the lower hole surface of the movable hole 3 is inclined, so that the ball has a tendency to move along the movable hole 3 towards the side away from the accommodating cavity 241. Thus, when the driving of the locking member 22 towards the connector 11 by the movable column 211 is released, the ball will automatically roll outward along the lower hole surface of the movable hole 3 and move to the unlocked state.

[0053] Even further, referring to Figure 3 As shown, the movable column 211 slides against the outer side of the inner shell 24, and the side of the movable column 211 in contact with the inner shell 24 is provided with a ball avoidance groove 5. When the button 21 slides downward, part of the ball enters the ball avoidance groove 5 to form an unlocked state; when the button 21 slides upward, the ball leaves the ball avoidance groove 5 to form a locked state.

[0054] Reference Figure 6 , in another embodiment of the present invention, in combination with the above embodiment, the locking member 22 can also adopt a slider structure. A slider avoidance groove 5 is provided on the movable column 211, and the lower end of the slider avoidance groove 5 is a slope for pushing against the slider so that the slider moves towards the locking groove 111.

[0055] Combined with Figure 2 Or 6, andFigure 7 and Figure 8 In one embodiment, several first hooks 242 are circumferentially and spacedly distributed along the upper end of the outer periphery of the inner shell 24, and a convex portion 243 extending radially outward is provided at the lower end. A first boss 2311 is provided on the inner wall of the installation space 231. The upper end of the inner shell 24 is engaged with the first boss 2311 through the first hook 242, and the lower end of the inner shell 24 abuts against the mouth of the installation space 231 at the lower end of the outer shell 23 through the convex portion 243, so as to be fixed in the installation space 231.

[0056] Further, the button 21 is provided with a second hook 212, and a second boss 2421 is provided on the side of the first hook 242 facing away from the first boss 2311. The second hook 212 and the second boss 2421 cooperate to limit the upper sliding limit of the button 21 in the upper space.

[0057] When the button 21 moves in the installation space 231, when it slides downward to abut against the inner shell 24, a sliding lower limit position is formed, and when it slides upward to the second hook 212 abuts against the second boss 2421, a sliding upper limit position is formed.

[0058] When the button 21 moves to the sliding upper limit, the top bead 2 and the connecting head 11 are in a locked state; when the button 21 moves to the sliding lower limit, the top bead 2 and the connecting head 11 are in an unlocked state.

[0059] To realize the conversion of the button 21 from its sliding lower position to the sliding upper limit position, an elastic member 6 is provided between the inner shell 24 and the button 21. One end of the elastic member 6 abuts against the button 21, and the other end abuts against the inner shell 24. The button 21 has a tendency to move towards its sliding upper limit position, so that the locking member in the button 21 is in the corresponding position in the locked state under normal conditions.

[0060] Reference Figure 8 To avoid the connecting head 11 rotating in the accommodating cavity 241 after the top bead 2 is connected to the connecting head 11 when the cooking pot lid 1 rotates. In some embodiments, a first limiting structure 112 is provided on the outer periphery of the connecting head 11, and a second limiting structure 7 is provided on the inner wall of the accommodating cavity 241. The first limiting structure 112 and the second limiting structure 7 cooperate to limit the circumferential rotation of the top bead 2 along the connecting head 11.

[0061] Wherein, the first limiting structure 112 and the second limiting structure 7 can adopt a convex and concave structure that matches each other, and are respectively provided on the surface of the connecting head 11 and the inner wall of the accommodating cavity 241 on the premise of not interfering with the connecting head 11 entering the accommodating cavity 241 to complete the connection.

[0062] Further, to facilitate the quick re - entry of the connecting head 11 into the receiving cavity 241 after the top bead 2 is separated from the connecting head 11 for connection. The upper end of the first limiting structure 112 is provided with a first guiding structure 1121, and the lower end of the second limiting structure 7 is provided with a second guiding structure 71.

[0063] It should be noted that the first guiding structure 1121 and the second guiding structure 71 respectively adopt inclined surface structures, which can narrow the upper end of the first limiting structure 112 and the lower end of the second limiting structure 7. This can prevent the upper end of the first limiting structure 112 and the lower end of the second limiting structure 7 from abutting against each other, thus avoiding interference when the connecting head 11 enters the receiving cavity 241.

[0064] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the respective embodiments involved.

[0065] The above - described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
