A spherical groove with a notch facing away from the air inlet hose is provided in the pipe joint, and a movable sphere for universal motion is rotatably connected in the spherical groove. A radially extending air guide channel is provided on the movable sphere, and one end of the air guide channel is connected to the outside world, and the other end is connected to the air inlet hose.

[0005] The utility model is further configured as follows: a locking screw with an end portion extending into the spherical groove and abutting against the movable sphere is threadedly connected on the pipe joint.

[0006] The utility model is further configured as follows: the locking screw is a hand-tightening locking screw.

[0007] The utility model is further configured as follows: an air guide cover is provided at one end of the air guide channel connected to the outside.

[0008] The utility model is further configured as follows: a handle is provided on the top of the pipe joint.

[0009] In summary, the utility model has the following beneficial effects:

[0010] 1. Because the pipe joint is provided with a swing seat with a built-in counterweight, the end of the air inlet hose at one end of the exhaust gas absorption end can realize the table swing function, which has low requirements on the layout environment and is flexible and convenient to use.

[0011] 2. The movable sphere can be universally rotated relative to the spherical groove, so that the direction of the air inlet for absorbing exhaust gas can be adjusted, thereby enhancing the exhaust gas absorption rate.

[0012] 3. The added air guide hood can expand the exhaust gas absorption range and make the exhaust gas absorption more thorough. BRIEF DESCRIPTION OF THE DRAWINGS
