[0016] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0017] The specific implementation of the utility model is described in detail below in combination with specific embodiments.

[0018] As shown in Figure 1 , Figure 2 and Figure 3 , the lid which can conveniently draw and add liquid provided by the utility model embodiment comprises a lid main body 1 and an upper cover 2, the upper cover 2 is installed on the lid main body 1 in a detachable manner, the lid main body 1 is provided with a gas pressure balance structure, the lid main body 1 is provided with two groups of threads, which are a first thread and a second thread, the diameters of the first thread and the second thread are different, the first thread and the second thread are respectively fixedly provided with a first sealing element and a second sealing element at one end close to the upper cover 2, the lid main body 1 is installed with an adapter 3, and the adapter 3 penetrates the upper cover.

[0019] In this embodiment, when installing, the adapter 3 is installed on the cover body 1, the cover body 1 is provided with an air pressure balancing structure, which can be an air hole groove, a plurality of air holes are arranged in the air hole groove, the number of air holes is six, the air holes are used to balance the air pressure inside and outside the container, the first filter cotton 4 is installed in the air hole groove, the air pressure balancing structure can also be two one-way valves, two one-way valves are installed, one one-way valve is used for exhaust, and one one-way valve is used for air intake, when the internal pressure of the container is too large, the one-way valve air intake limit is reached, the exhaust one-way valve is used for exhaust, and the air pressure inside and outside the container is balanced; when the internal pressure of the container is too small, the one-way valve air intake limit is reached, the exhaust one-way valve is used for air intake, and the air pressure inside and outside the container is balanced; the cover body 1 is provided with a water accumulation groove, the second filter cotton 5 is installed in the water accumulation groove, the diameters of the first thread and the second thread on the cover body 1 are different, and the first thread and the second thread are arranged in a staggered manner, the first sealing element and the second sealing element are respectively a first sealing ring 6 and a second sealing ring 7, and the first sealing ring 6 and the second sealing ring 7 are arranged at the roots of the first thread and the second thread respectively.
