[0025] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0026] See also Figures 1 to 9, an exhaust assembly suitable for a mobile air conditioner, comprising an exhaust assembly 1, the exhaust assembly 1 comprising a window frame 2, an exhaust pipe joint 3 connected to the window frame 2, a connecting structure 4 for fixing the window frame 2 and the exhaust pipe joint 3, and a sealing member 5 for sealing the connection between the window frame 2 and the exhaust pipe joint 3. The window frame 2 not only connects to the exhaust pipe joint 3, but also connects to the window, while the exhaust pipe joint 3 is used to connect to the exhaust pipe of the mobile air conditioner. The connecting structure 4 is used to fix the connection between the window frame 2 and the exhaust pipe joint 3, ensuring stability and sealing between the two. Furthermore, the sealing member 5 is used to seal the connection between the window frame 2 and the exhaust pipe joint 3, effectively improving the sealing performance of the exhaust assembly 1, preventing the hot air in the exhaust pipe from flowing back and the outdoor air from entering the room. In summary, by providing the connecting structure 4, the window frame 2 is achieved. And the exhaust pipe joint 3 is fixedly connected, and a sealing member 5 is provided at the connection between the window frame 2 and the exhaust pipe joint 3. When the exhaust pipe joint 3 and the window frame 2 are in a connected state, the sealing member 5 can effectively ensure the sealing of the window frame 2 and the exhaust pipe joint 3, effectively improving the connection stability and sealing of the window frame 2 and the exhaust pipe joint 3, and solving the problem that the existing exhaust pipe and the window frame are connected by a snap-fitting manner, there is a certain gap between the exhaust pipe and the window frame, the sealing and connection stability are insufficient, and it is easy for hot air to flow back, outdoor air to enter the room, and the exhaust pipe to fall off.

[0027] Furthermore, the window frame 2 is provided with an exhaust hole 21 for the exhaust pipe joint 3 to extend into, the exhaust pipe joint 3 includes a first connecting portion 31 connected to the exhaust pipe, and a second connecting portion 32 connected to the first connecting portion 31, the connecting structure 4 includes a fixing portion 41 provided on the second connecting portion 32, and a connecting hole 42 provided on the window frame 2, and a fastener passes through the connecting hole 42 and the fixing portion 41 to fix the exhaust pipe joint 3 to the window frame 2. The design of the exhaust hole 21 provides space for the connection between the window frame 2 and the exhaust pipe joint 3. At the same time, the shape and size of the exhaust hole 21 should match the shape and size of the second connecting part 32 of the exhaust pipe joint 3 to improve the connection stability and sealing between the exhaust pipe joint 3 and the window frame 2. Furthermore, the first connecting part 31 is used to connect to the exhaust pipe of the mobile air conditioner, and the second connecting part 32 is used to connect to the exhaust hole 21 of the window frame 2. The fixing part 41 provided on the second connecting part 32 is used to cooperate with the connecting hole 42 on the window frame 2. The fastener passes through the connecting hole 42 and is connected to the fixing part 41 to realize the fixed connection between the window frame 2 and the exhaust pipe joint 3, thereby effectively improving the connection stability and reliability of the exhaust pipe joint 3 and the window frame 2.

[0028] Furthermore, a fitting portion 311 for fixing the exhaust pipe is provided on the inner side of the first connecting portion 31, and the outer diameter of the first connecting portion 31 is larger than the outer diameter of the second connecting portion 32, so that the exhaust pipe joint 3 forms a contact surface 33, and the diameter of the exhaust hole 21 is greater than or equal to the outer diameter of the second connecting portion 32, and the outer diameter of the first connecting portion 31 is larger than the diameter of the exhaust hole 21. The fitting portion 311 is designed to fix the exhaust duct of the mobile air conditioner. It can be designed as a threaded interface, a snap-on structure or other forms of connection mechanisms to ensure a tight connection and easy disassembly between the exhaust duct and the first extension portion 31, effectively improving the connection stability and convenience of installation and disassembly between the exhaust duct and the exhaust duct joint 3. Furthermore, the outer diameter of the first connection portion 31 is larger than the outer diameter of the second connection portion 32, which means that the second connection portion 32 can extend into the exhaust hole 21, but the first connection portion 31 cannot pass through the exhaust hole 21, which serves to fix the relative position of the exhaust duct joint 3 and the window frame 2. At the same time, this design enables the exhaust duct joint 3 to form an abutting surface 33 abutting against the window frame 2, which serves to seal the connection gap between the second connection portion 32 and the exhaust hole 21, effectively improving the sealing of the exhaust assembly 1.

[0029] Furthermore, the connecting structure 4 also includes a limiting column 43 connecting the fixing portion 41 and the abutting surface 33, and a limiting groove 44 provided on the exhaust hole 21. The limiting column 43 is located between the fixing portion 41 and the abutting surface 33. The limiting column 43 abuts against the limiting groove 44 to fix the exhaust pipe joint 3 to the window frame 2. The matching design of the limiting column 43 and the limiting groove 44 provides an additional fixing structure for the connection between the exhaust pipe joint 3 and the window frame 2. When the exhaust pipe joint 3 is extended into the exhaust hole 21 of the window frame 2, the exhaust pipe joint 3 is rotated so that the limiting column 43 abuts against the limiting groove 44, thereby achieving the preliminary fixation of the exhaust pipe joint 3 and the window frame 2. Then, a fastener is used to pass through the connecting hole 42 of the window frame 2 and the fixing part 41 of the exhaust pipe joint 3 to firmly connect the two together, further fixing the exhaust pipe joint 3 and the window frame 2, thereby ensuring the connection stability and sealing between the exhaust pipe joint 3 and the window frame 2.

[0030] Furthermore, the exhaust hole 21 is provided with a limiting hole 211 for the fixing portion 41 to pass through, the limiting hole 211 is communicated with the limiting groove 44, and the angle between the fixing portion 41 and the sealing member 5 is equal to the angle between the limiting hole 211 and the connecting hole 42. The design of the limiting hole 211 for the fixing portion 41 to pass through means that the second connecting portion 32 can pass through the exhaust hole 21 as a whole. Before the second connecting portion 32 extends into the exhaust hole 21, the fixing portion 41 needs to be aligned with the limiting hole 211. After the second connecting portion 32 extends into the exhaust hole 21, the exhaust pipe joint 3 is rotated to make the limiting column 43 abut against the limiting groove 44, thereby achieving preliminary fixation of the exhaust pipe joint 3 and the window frame 2. Furthermore, the clamping force between the fixing portion 41 and the sealing member 5 is reduced. The angle is equal to the angle between the limiting hole 211 and the connecting hole 42, which means that when the limiting column 43 is rotated to abut against the limiting groove 44, the fixing portion 41 can be aligned with the connecting hole 42, and then a fastener is used to pass through the connecting hole 42 and the fixing portion 41 to fix the exhaust pipe joint 3 to the window frame 2. At the same time, the sealing member 5 is aligned with the limiting hole 211 to seal the limiting hole 211. Such a design effectively improves the connection stability and sealing between the exhaust pipe joint 3 and the window frame 2.

[0031] Furthermore, the sealing member 5 is connected to the side of the first connecting portion 31. When the exhaust pipe joint 3 is connected to the window frame 2, the sealing member 5 covers the limiting hole 211. The number of the sealing members 5 is the same as the number of the limiting holes 211. This design ensures that after the fixing portion 41 passes through the limiting hole 211 and rotates to abut against the limiting groove 44, the limiting hole 211 will not become a channel for air leakage. At the same time, the number of the sealing members 5 is the same as the number of the limiting holes 211, ensuring that each limiting hole 211 can be covered by a corresponding sealing member 5, effectively improving the sealing performance of the exhaust assembly 1.

[0032] Furthermore, the height a of the limiting column 43 is greater than or equal to the depth of the exhaust hole 21, and the number of the fixing parts 41 is at least two and symmetrically arranged. The height a of the limiting column 43 is greater than or equal to the depth of the exhaust hole 21, which means that the fixing part 41 can completely pass through the exhaust hole 21 and smoothly abut against the limiting groove 44. At the same time, the number of the fixing parts 41 is at least two. Such a design can effectively increase the fixing points of the exhaust pipe joint 3 and the window frame 2, and can effectively improve the connection stability and reliability of the exhaust pipe joint 3 and the window frame 2. In addition, the fixing parts 41 are symmetrically arranged on both sides of the exhaust pipe joint 3, which can improve the connection strength between the exhaust pipe joint 3 and the window frame 2, prevent the fixing parts 41 from being damaged due to external forces, and effectively improve the service life of the exhaust assembly 1.

[0033] Furthermore, a partition 34 is provided on the inner side of the exhaust pipe joint 3. The partition 34 is in the form of a diamond mesh, a rectangular mesh, a hexagonal mesh, or a circular mesh. The partition 34 provided on the inner side of the exhaust pipe joint 3 can effectively prevent external objects (such as insects, dust, and mice, etc.) from entering the exhaust pipe while not affecting air flow, thereby effectively improving the practicality and functionality of the exhaust assembly 1. The partition 34 can be in the form of a diamond mesh, a rectangular mesh, a hexagonal mesh, or a circular mesh. These shapes all have good strength and stability, while providing a relatively large opening area, which is conducive to air flow. Therefore, selecting one of the above shapes as the shape of the partition 34 can effectively improve the strength and stability of the partition 34 while maintaining good ventilation.

[0034] Furthermore, the window frame 2 includes a first window frame 22 and a second window frame 23 connected to the first window frame 22, the first window frame 22 is provided with a first guiding portion 221, the second window frame 23 is provided with a second guiding portion 231, the first guiding portion 221 and the second guiding portion 231 are cooperated and connected to make the first window frame 22 and the second window frame 23 slidably connected, the first guiding portion 221 and the second guiding portion 231 are respectively provided with a first extension portion 222 and a second extension portion 232, and a slot 24 for fixing the window frame 2 and the window is formed between the first extension portion 222 and the second extension portion 232. The window frame 2 is composed of the first window frame 22 and the second window frame 23, and the sliding connection between the first guide portion 221 of the first window frame 22 and the second guide portion 231 of the second window frame 23 is realized, so that the window frame 2 can be adapted to windows of different sizes by adjusting the relative positions of the first window frame 22 and the second window frame 23, effectively improving the versatility and practicality of the exhaust component 1. Furthermore, the first extension portion 222 of the first guide portion 221 and the second extension portion 232 of the second guide portion 231 form a card slot 24 for fixing the window frame 2 to the window, and at the same time, the first extension portion 221 and the second extension portion 231 can seal the connection between the window frame 2 and the window, effectively improving the sealing performance of the exhaust component 1.

[0035] Furthermore, the first connecting portion 221 is provided with a first abutting portion 223 abutting against the second connecting portion 231 , and the second connecting portion 231 is provided with a second abutting portion 233 abutting against the first connecting portion 221 . The cross-sections of the first abutting portion 223 and the second abutting portion 233 are arc-shaped. The design of the first abutment portion 223 and the second abutment portion 233 ensures the stability and smoothness of the first window frame 22 and the second window frame 23 during the sliding connection process, and also plays a role in sealing the connection between the first window frame 22 and the second window frame 23, effectively improving the sealing performance of the exhaust assembly 1. Furthermore, the cross-sectional shape of the first abutment portion 223 and the second abutment portion 233 is set in an arc shape, which can effectively reduce the friction between the first guide portion 221 and the second guide portion 231, so that the sliding connection between the first window frame 22 and the second window frame 23 is smoother, and at the same time reduces the wear between the two caused by the sliding connection. Secondly, the arc design can disperse the pressure during the sliding process, effectively improving the service life of the window frame 2.
