[0040] Please refer to Figure 1 and Figure 2An oil-collecting device for a compressor breather according to an embodiment of the present invention includes: a cylinder 1 and a cylindrical tube 2.

[0041] The top of the cylinder 1 is open and the bottom is provided with a through hole 11. The cylinder 1 is cylindrical and is used to collect lubricating oil.

[0042] The cylindrical tube 2 is set as one and has a through hole 11. The cylindrical tube 2 is set vertically and fixedly connected to the cylinder 1. The top end of the cylindrical tube 2 is located inside the cylinder 1 and is used to connect the breathing cap 3. The bottom end of the cylindrical tube 2 is located outside the cylinder 1 and is used to connect the breathing tube 4. The top end of the cylindrical tube 2 is lower than the top opening of the cylinder 1.

[0043] The cylindrical tube 2 connects the breathing tube 4 and the breathing cap 3. When the respirator expels gas, the gas enters the cylindrical tube 2 from the breathing tube 4, and then enters the breathing cap 3 from the cylindrical tube 2. The breathing cap 3 has a breathing hole from which lubricating oil flows out.

[0044] The top opening of the cylinder 1 is higher than the top of the cylindrical tube 2, and the cylinder 1 is set to be closed at the bottom and form a container. The lubricating oil flowing out of the breathing hole will be collected inside the cylinder 1 and will not continue to flow down and contaminate the respirator.

[0045] In this embodiment, the oil-collecting device for the compressor's breather is installed on the breather pipe 4 via the cylindrical tube 2. The cylinder 1 allows the lubricating oil discharged from the breather cap 3 to be collected, preventing contamination of the breather, reducing safety hazards, and improving production safety.

[0046] The connection point between the cylindrical tube 2 and the cylinder 1 is located at the center of the bottom end of the cylinder 1. This structure facilitates the design of the oil-collecting device for the compressor's breather. Specifically, a cylindrical tube 2 can be prepared first, and then the cylinder 1 can be welded to the outer circumference of the cylindrical tube 2, forming a structure in which the cylindrical tube 2 passes through the cylinder 1.

[0047] The oil-collecting device for the compressor breather in this embodiment also includes an oil drain pipe 5, which is connected to the cylinder 1 and communicates with the interior of the cylinder 1.

[0048] The oil drain pipe 5 allows the lubricating oil contained in the cylinder 1 to be discharged from the oil drain pipe 5, reducing the liquid level in the cylinder 1 and facilitating the cleaning and maintenance of the oil holding device.

[0049] The oil drain pipe 5 is connected to the bottom end of the cylinder 1. This structure allows the lubricating oil at the bottom of the cylinder 1 to be discharged through the oil drain pipe 5.

[0050] The oil-collecting device for the compressor's breather also includes an oil drain valve 6, which is installed on the oil drain pipe 5 and is used to control the opening and closing of the oil drain pipe 5. When the oil drain valve 6 is opened, the lubricating oil in the cylinder 1 can be discharged through the oil drain pipe 5. When the oil drain valve 6 is closed, the oil drain pipe 5 is also closed, and the lubricating oil in the cylinder 1 cannot be discharged through the oil drain pipe 5, so the cylinder 1 can normally store lubricating oil.

[0051] In existing technology, the breathing tube 4 and breathing cap 3 of a respirator are directly connected. However, in this embodiment, the oil-collecting device of the respirator for the compressor is located between the breathing tube 4 and the breathing cap 3. The top end of the cylindrical tube 2 is connected to the breathing cap 3, and the bottom end of the cylindrical tube 2 is connected to the breathing tube 4, thereby installing the oil-collecting device of the respirator for the compressor. Specifically, the top end of the cylindrical tube 2 is provided with a first thread 21, which is located on the outer wall of the top end of the cylindrical tube 2 and is used to connect with the breathing cap 3. The bottom end of the cylindrical tube 2 is provided with a second thread 22, which is located on the inner wall of the bottom end of the cylindrical tube 2 and is used to connect with the breathing tube 4. In other embodiments, the first thread 21 can also be located on the inner wall of the cylindrical tube 2, and the second thread 22 can also be located on the outer wall of the cylindrical tube 2. The configuration can be adjusted according to actual needs in specific implementations.

[0052] This embodiment also provides a breather for a compressor, including a breather body 7, a breather cap 3, a breather tube 4, a connecting tube 8, and the oil-collecting device for the breather for the compressor described above.

[0053] The breathing tube 4 is installed on the respirator body 7, and the breathing tube 4 is vertically positioned and extends upward from the respirator body 7.

[0054] The oil-filling device for the compressor's breather, the cylindrical tube 2 connects the breather tube 4 and the breather cap 3.

[0055] The connecting pipe 8 is installed on the respirator body 7 and is used to connect to the compressor.

[0056] With this structure, the oil collection device for the compressor's breather, as part of the breather, can collect the lubricating oil discharged from the breather hole, preventing contamination of the breather, reducing safety hazards, and improving production safety.

[0057] A third thread 41 is provided at the top end of the breathing tube 4. The third thread 41 is located on the outer wall of the top end of the breathing tube 4 and is used to connect to the cylindrical tube 2. In other embodiments, the third thread 41 may also be located on the inner wall of the cylindrical tube 2. The specific configuration can be determined according to actual needs.

[0058] The connecting pipe 8 is provided with a fourth thread 81, which is used to connect to the compressor. Similarly, the fourth thread 81 can be set as an external thread or an internal thread, which can be set according to actual needs in specific implementation.

[0059] The working process of this utility model is as follows: the top opening of the cylinder 1 is higher than the top of the cylindrical tube 2, and the cylinder 1 is set to be closed at the bottom and form a container. The lubricating oil flowing out of the breathing hole will be collected inside the cylinder 1 and will not continue to flow down and contaminate the respirator.

[0060] In summary, this utility model embodiment provides a breather for a compressor and its oil-collecting device. The oil-collecting device for the compressor breather is installed on the breather pipe 4 through the cylindrical tube 2. The lubricating oil discharged from the breather cap 3 can be collected through the cylindrical body 1, preventing contamination of the breather, reducing safety hazards, and improving production safety.

[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
