[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings:

[0028] An automatic opening and closing oil pot lid, such as Figures 1-8 As shown, it includes a top cover 1 and a base 2. The front end of the base 2 is provided with an oil outlet 5 that passes through the interior of the base 2. The oil outlet 5 is connected to the kettle body 6 and can accommodate edible oil and other liquids in the kettle body 6 to flow out. The rear end side wall of the base 2 is concave to form a first accommodating cavity 21. The base 2 is provided with a second accommodating cavity 22 between the oil outlet 5 and the first accommodating cavity 21. Figure 3 It can be seen that on the base 2, the oil outlet 5, the second accommodating cavity 22, and the first accommodating cavity 21 are arranged in front and back from left to right; Figure 2It can be seen that the rear end of the top cover 1 is provided with a first connecting portion 11, and the main part of the top cover 1 is provided with a second connecting portion 12, and the second connecting portion 12 is preferably provided in the center of the top cover 1; the second connecting portion 12 can be accommodated at the front end of the second accommodating cavity 22 to ensure that the top cover 1 is covered without obstruction, and the side walls of the first accommodating cavity 21 are relatively provided with two first connecting columns 211, and the first connecting portion 11 is relatively provided with two first connecting holes 111. The first connecting columns 211 are installed in the first connecting holes 111 to form a rotatable connection with the top cover 1, so that the top cover 1 can be rotatably opened and closed to realize the opening or closing of the base 2, and the second connecting columns 311 are relatively provided on both sides of the rotating portion 31, and the side walls of the rear end of the second accommodating cavity 22 are provided with two relatively For the second connecting hole 221, the second connecting column 311 is installed in the second connecting hole 221 to form a rotatable connection between the counterweight 3 and the rear end of the second accommodating chamber 22. It should be noted that the rotational connection between the first connecting part 11 and the first accommodating chamber 21, and the rotational connection between the counterweight 3 and the second accommodating chamber 22 can also adopt other conventional rotational connection methods, such as a hinged method; the counterweight 3 includes a counterweight part 32 and a rotating part 31 and a driven part 33 respectively connected to the counterweight part 32. The angle between the rotating part 31 and the driven part 33 is less than 180 degrees, so that the rotating part 31 and the driven part 33 can be ensured to be on the same side of the vertical plane. Preferably, the angle between the rotating part 31 and the driven part 33 is set to 90 degrees. Figure 5 The angle between the straight line B where the rotating part 31 is shown and the realization A where the driven part 33 is shown is 90 degrees. One end of the rotating part 31 is axially connected to the rear end side wall of the second accommodating chamber 22 so that the counterweight 3 can rotate in the second accommodating chamber 22. The second connecting part 12 can be directly or movably connected to the driven part 33 through the connecting rod 4 to link the top cover 1 with the counterweight 3. The second connecting part 12, the connecting rod 4 and the driven part 33 are rotatable shaft connections. The shaft connection method can enable the connecting rod 4 to produce more various motion forms during the movement process, which can save the space occupied by the connecting rod 4 and the counterweight 3. This can moderately reduce the volume of the second accommodating chamber 22 and avoid the base 2 from being too large. At the same time, since the top cover 1 and the counterweight 3 linked to it have two axes at the connection between the two and the base 2, namely the axis where the first connecting column 211 is located and the axis where the second connecting hole 221 is located, the change in the movement form of the connecting rod 4 can coordinate the movement of the above two axes so that the top cover 1 can open and close smoothly on the base 2.

[0029] like Figure 6 As shown, when not in use, the base 2 is placed horizontally, the counterweight 3 pulls the top cover 1 downward under the action of gravity, the base 2 supports the top cover 1, and the top cover 1 has a downward movement pulling force, so that a tight buckling state can be formed; Figure 8As shown, when in use, the base 2 is rotated downward, that is, the kettle body 6 is rotated downward. Since the counterweight 3 and the top cover 1 are connected to each other, under the common gravity of the counterweight 3 and the top cover 1, the top cover 1 returns to the inclined shape in the natural state and no longer rotates. It should be noted that at this time, the vertical extension line with the connection between the rotating part 31 and the second accommodating chamber 22 as the center point is X, the total weight of the counterweight 3 and the top cover 1 is the gravity source, and the center of the counterweight part 32 is on the right side (rear side) of the X extension line. The base 2 continues to rotate to make the oil outlet 5 continue to tilt, and the liquid can flow out of the oil outlet 5.

[0030] In order to provide further support in the open state, such as Figure 2 and Figure 8 As shown, a limit block 112 can be provided at the rear end of the top cover 1. The limit block 112 is adjacently arranged on the front side of the first connecting portion 11. After the top cover 1 returns to its naturally inclined shape and no longer rotates, the limit block 112 abuts against the top surface of the base 2 to form a limit.

[0031] For ease of processing, the counterweight block 322 is made of metal. Except for the counterweight part 3, the oil pot lid is made of plastic. The counterweight part 32 can be integrally provided with a counterweight cavity 321 with an accommodating space, and the counterweight block 322 can be detachably installed in the counterweight cavity 321.

[0032] From the above description, it can be seen that the above embodiment achieves the following technical effects: the counterweight pulls the top cover downward under the action of gravity, the base supports the top cover, and the top cover has a downward pulling force, so that a tight buckling state can be formed, which makes the sealing effect of the oil can better. At the same time, the balance seesaw structure is not adopted, which makes the design of the proportion between the counterweight and the top cover simpler, enhances the flexibility of designing different sizes and shapes, and improves production efficiency.

[0033] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
