[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-6A plastic bucket lid with an exhaust structure includes a bucket lid 1, an exhaust column 2 installed on the upper part of the bucket lid 1, a lifting cover 5 installed inside the exhaust column 2, a number of notches 51 opened at the bottom of the lifting cover 5, a number of exhaust grooves 22 opened on the inner wall of the exhaust column 2 located above the lifting cover 5, and the lifting cover 5 and the exhaust column 2 are connected by a spring 8. A sealing cover 4 is movably fitted onto the outer wall of the exhaust column 2. The bottom wall of the sealing cover 4 is connected to the outer wall of the exhaust column 2 through a rubber diaphragm 7, and the inside of the sealing cover 4 is connected to the exhaust column 2 through a spring 31. A hand-tightening bolt 3 is rotatably installed on the top of the sealing cover 4, and the hand-tightening bolt 3 is screwed to the top of the exhaust column 2. Among them, the top center of the exhaust column 2 is provided with a screw hole 23, which is used to screw in the hand-tightening bolt 3.

[0017] The middle part of the hand-tightening bolt 3 is rotatably mounted on the upper wall of the sealing cover 4, and the bottom is threaded and extends downward, and is screwed into the screw hole 23.

[0018] The outer wall of the exhaust column 2 is provided with a rubber ring 21, and a rubber ring 42 is provided above the rubber ring 21. The rubber ring 42 is installed on the inner wall of the sealing cover 4. When the rubber ring 42 and the rubber ring 21 are squeezed and contacted, a seal is formed.

[0019] The bottom of the exhaust column 2 passes through the barrel cover 1.

[0020] The exhaust column 2 has an internal cavity and a through bottom. A lifting cover 5 is installed inside the exhaust column 2 to limit its movement. The lifting cover 5 can move vertically inside the exhaust column 2.

[0021] The inner wall of the exhaust column 2 is fitted with a seal 6, which is pressed against the outer wall of the lifting cover 5 to achieve a seal.

[0022] A gap is left between the inner wall of the sealing cover 4 and the outer wall of the exhaust column 2 to allow gas to flow. A spring 31 is installed on the inner top wall of the sealing cover 4, and the other end of the spring 31 is connected to the upper wall of the exhaust column 2.

[0023] Multiple vent holes 71 are opened in the middle of the rubber diaphragm 7.

[0024] A pair of sliders 41 are symmetrically installed on both sides of the inner wall of the sealing cover 4. The sliders 41 are limited and slidably installed in the groove 24 opened on the outer wall of the exhaust column 2.

[0025] In this embodiment, after the lid 1 is assembled with the barrel body, when overpressure gas is generated inside the barrel body, the gas pressure pushes the lifting cover 5 inside the exhaust column 2 to move upward, so that the notch 51 at its bottom coincides with the exhaust groove 22 on the side wall of the exhaust column 2. The overpressure gas then enters the cavity formed by the exhaust column 2 and the sealing cover 4 through the coincident channel, and is finally discharged through the vent 71 in the middle of the rubber diaphragm 7.

[0026] The rubber diaphragm 7 is installed facing downwards, which can effectively prevent moisture from entering from the sides or top.

[0027] When it is necessary to seal the exhaust passage or perform a waterproof seal, turn the hand-tightening bolt 3 to engage with the screw hole 23 at the top of the exhaust column 2, driving the sealing cover 4 to move down as a whole. At this time, the rubber ring 42 on the inner wall of the sealing cover 4 gradually approaches and squeezes into contact with the rubber ring 21 on the outer wall of the exhaust column 2 to form a seal, thereby isolating the gas inside and outside the barrel.

[0028] Among them, spring 31 provides stable support for sealing cover 4, and sealing cover 4 achieves smooth axial movement through the cooperation of slider 41 and slide groove 24, ensuring smooth execution of sealing operation.

[0029] In addition, it should be noted that the rubber diaphragm 7 is flexible to accommodate the deformation displacement of the sealing cap 4 during its movement.

[0030] It is worth noting that the seal 6 is a conventional sealing component in the field, and its material properties and sealing principle are common knowledge to those skilled in the art. In addition, the wear life of the seal is within the normal service life of this device, and will not be described in detail here.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
