The second connector 102 is provided with a second through hole 105, and the second connector 102 is located in the first through hole 103 and connected to the yoke 101.

Referring to fig. 3 and 4, the air duct assembly according to the embodiment of the second aspect of the present invention includes the air duct joint 100 according to the embodiment of the first aspect of the present invention, a second air duct 301 and a first air duct 302, wherein the second air duct 301 is connected to the second connector 102, the second through hole 105 is communicated with the second air duct 301, the first air duct 302 is sleeved on the outer side of the second air duct 301, the clamp 101 is sleeved on the outer side of the first air duct 302, the first through hole 103 is communicated with the first air duct 302, and the outer side of the first air duct 302 is provided with an annular groove 401 matched with the clamping protrusion 104.

During the equipment, connect second tuber pipe 301 through second connecting piece 102, open clamp 101, put into clamp 101 with first tuber pipe 302, close clamp 101 again, and through fastener locking clamp 101, joint arch 104 butt annular 401 of first tuber pipe 302 prevents that first tuber pipe 302 from droing, thereby realizes the connection of second tuber pipe 301 and first tuber pipe 302, owing to do not need the screw to pass first tuber pipe 302, thereby can avoid first tuber pipe 302 to receive the destruction.

It should be noted that the first air duct 302 can be used for air exhaust or air intake. Correspondingly, the second wind pipe 301 can be used for air intake and also for air exhaust. For example, in some embodiments, the first air duct 302 is used for supplying air, the second air duct 301 is used for exhausting air, outdoor air enters the air inlet of the mobile air conditioner through the first air duct 302 and the first through hole 103, and the air after heat exchange in the mobile air conditioner is exhausted to the outside through the second through hole 105 and the second air duct 301. Compared with a double-air-pipe structure consisting of two split independent air pipes, the air pipe assembly provided by the embodiment of the invention has the advantages that the integrity is better, the structure is simple and attractive, a user can conveniently install and adjust the double-air-pipe structure, and the user experience is improved.

In some embodiments, second connector 102 is provided with a snap 106, and snap 106 is used to connect with the end of second air duct 301. Referring to fig. 3 and 4, the end of the second air duct 301 is provided with a locking groove 402 engaged with the locking buckle 106, and the second connector 102 is connected to the second air duct 301 through the locking buckle 106 and the locking groove 402, so that the second air duct 301 can be quickly mounted and dismounted, and the second air duct 301 can be prevented from being damaged. It is understood that in other embodiments, the second connector 102 and the second air duct 301 can be connected by screws, rivets or clips.

In some embodiments, the second connecting member 102 is eccentrically disposed inside the band 101, so that the second air duct 301 can be eccentrically disposed inside the first air duct 302. In the related art, the structures of some double air ducts are concentrically arranged, and the concentrically arranged inner pipes are unevenly stressed and unstable and easily float relative to the outer pipes. During the drunkenness, the inner tube blocks the wind gap easily, leads to the ventilation between outer tube and the inner tube to be obstructed to influence the operation of mobile air conditioner and produce the noise easily. Compared with the concentric arrangement of the second connecting piece 102 and the clamp 101, namely the concentric arrangement of the second air pipe 301 and the first air pipe 302, the air pipe joint 100 provided by the embodiment of the invention has the advantage that the second air pipe 301 is mainly subjected to one-side wind power, the movement of the second air pipe 301 is reduced, and the influence of the second air pipe 301 on the ventilation of the first air pipe 302 is further reduced.

Meanwhile, the air pipe assembly is beneficial to reducing the installation space required by one side of the mobile air conditioner, and the effective space of the mobile air conditioner can be reasonably utilized, for example, the rear side of the mobile air conditioner needs to be arranged close to a wall, the installation space in the front-rear direction is limited, and the installation space in the left-right direction is larger.

It should be noted that the oblong shape may be defined as: two points on the circle on the same diameter or two arcs symmetrical about the circle center are selected, and the circle is stretched along the straight line or the arc line to form a graph. For example, the oblong shape may be a racetrack circle formed by the cross-section of the first through-hole 103 as shown in fig. 1; of course, the oblong shape may also be formed as an oval or a square with rounded corners.

Referring to fig. 1 and 2, in some embodiments, the cross section of the second through hole 105 is circular, which is beneficial to the uniform stress of the second air pipe 301, and the second air pipe 301 is not easy to distort in the process of stretching or shrinking the second air pipe 301, and meanwhile, in the process of air outlet of the first air pipe 302, the second air pipe 301 is not easy to shift, so that the influence of the second air pipe 301 on the ventilation of the first air pipe 302 is reduced.
