[0133] In some of the embodiments, the third valve body 620 includes but is not limited to a ball valve.

[0134] The method of using this embodiment is as follows:

[0135] During actual use, the staff inserts the first pipeline 210 into the oil drum and screws the seal 110 into the oil outlet of the oil drum cover;

[0136] Then, the staff connects the second pipeline 310 to the container so that the liquid taken out from the oil barrel is placed in the container;

[0137] Then, the staff connects the pressurized air pipe 430 to the air compressor, and opens the air compressor and the first valve body 410, so that the air compressor can deliver compressed air to the oil barrel, and by changing the air pressure in the oil barrel, the liquid in the oil barrel can enter the container through the first pipeline 210 and the second pipeline 310;

[0138] Finally, the staff opens the third valve body 620, so that the pressurized air pipe 430, the connecting air pipe 610, the first pipeline 210 and the second pipeline 310 are connected to each other, so that the compressed air can purge the first pipeline 210 and the second pipeline 310 to drain the liquid in the first pipeline 210 and the second pipeline 310;

[0139] After the liquid in the oil barrel is taken out, the staff turns off the air compressor and the first valve body 410 and opens the second valve body 510, so that the compressed air in the oil barrel can be discharged to relieve the pressure of the oil barrel.

[0140] The advantage of this embodiment is that, by providing a connecting component between the pressurizing component and the oil outlet component, the pressurizing component can purge the oil suction component and the oil outlet component through the connecting component, thereby improving the cleanliness of the entire pipeline.

[0142] This embodiment relates to the oil drum in the utility model.

[0143] like Figure 6 As shown, an oil drum comprises an oil drum component 700 and the pneumatic liquid extraction device as described in Example 1 and Example 2. The pneumatic liquid extraction device is arranged at the oil outlet of the oil drum component 700.

[0144] It should be noted that the oil barrel components 700 are all standard oil barrel components (i.e., the prior art) and will not be described in detail here.

[0145] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0146] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
