[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] In the description of the present invention, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0048] In the description of the present invention, it is necessary to understand that descriptions involving orientation, such as up, down, left, right, etc., the orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0050] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0051] Reference Figures 1 to 3 As shown, according to the air duct 200 of the first embodiment of the present invention, the air duct 200 is a pipe with ventilation function, for example, an air duct for an air conditioner, or an air duct for an air filter. Figure 12 shows that the air duct 200 is connected to the air conditioner of the integrated air conditioner 100. The air duct 200 has a first air duct body 211 and a second air duct body 213, and the first air duct body 211 and the second air duct body 213 are connected and enclosed to form a ventilation cavity. In addition, a partition wall 212 is provided, and the two ends of the partition wall 212 are respectively connected to the connection 216 of the first air duct body 211 and the second air duct body 213, and the partition wall 212 and the first air duct body 211 are enclosed to form a first air duct 214, and the partition wall 212 and the second air duct body 213 are enclosed to form a second air duct 215. The first air duct 214 and the second air duct 215 are separated from each other and arranged separately. By arranging a partition wall 212 inside the air duct 200 to separate the first air duct 214 and the second air duct 215, the first air duct 214 and the second air duct 215 can be arranged in the air duct 200 to be separated from each other, so that during installation, only the air duct 200 needs to be installed to install the corresponding first air duct 214 and second air duct 215, without the need to install two ventilation ducts separately, for example, the air inlet duct and the air outlet duct are installed separately, thereby improving the installation efficiency. In some embodiments, the first air duct body 211, the second air duct body 213 and the partition wall 212 are all retractable structures, that is, the air duct 200 is retractable. By arranging the air duct 200 in a retractable manner, the air duct 200 can be made suitable for different installation environments. For example, sometimes a longer air duct 200 is needed, in which case the air duct 200 can be lengthened, and sometimes a shorter air duct 200 is needed, in which case the air duct 200 needs to be compressed accordingly. Providing a retractable structure can also facilitate storage, for example, Figure 1 As shown, when the integrated air conditioner 100 is not in use, the air duct 200 can be conveniently stored at the rear of the integrated air conditioner 100 to keep it tidy.

[0052] Reference Figures 4 to 6 As shown, in some embodiments, the cross-section of the peripheral wall of the air duct 200 is set to an oblong shape and the cross-section of the peripheral wall of the first air duct 214 is set to a circle; or the cross-section of the peripheral wall of the air duct 200 is set to a rectangle and the cross-section of the peripheral wall of the first air duct 214 is set to a rectangle; or the cross-section of the peripheral wall of the air duct 200 is set to a quasi-rectangular shape and the cross-section of the peripheral wall of the first air duct 214 is set to a quasi-rectangular shape. Any two opposite sides of the quasi-rectangular shape and the quasi-rectangular shape are equal or at least approximately equal and each includes at least one set of opposite sides containing a circular arc. The above-mentioned various shapes of the air duct 200 can be applied to the corresponding air conditioner, so the air inlet and outlet channels of the air conditioner can be set relatively flexibly as needed. It is expected that the air duct 200 can also be set to any other suitable shape, for example, the cross-section is other polygonal or irregular shapes.

[0053] Reference Figures 4 to 6As shown, in some embodiments, the first air duct body 211, the second air duct body 213 and the partition wall 212 are integrally formed. This can reduce the number of processes and ensure strength. The one-piece manufacturing can adopt corresponding manufacturing methods depending on the type and length of the pipeline, including but not limited to injection molding, cutting and other manufacturing methods. It can be expected that the first air duct body 211, the second air duct body 213 and the partition wall 212 can also be made in the form of assembly. For example, the first air duct body 211 and the second air duct body 213 are first made, and the first air duct body 211 and the second air duct body 213 are surrounded by a ventilation cavity, and then the partition wall 212 is inserted into the ventilation cavity to separate the first air duct 214 and the second air duct 215. It is also possible to first integrally form any two of the first air duct body 211, the second air duct body 213, and the partition wall 212, and then install the components that have not yet been assembled. The assembly method can be any suitable method, including but not limited to clamping and bonding.

[0054] Reference Figures 8 to 9 As shown, in some embodiments, the first air duct body 211, the second air duct body 213 and the partition wall 212 are all corrugated and have a plurality of wave peak structures 220, wherein the wave peak structure 220 of the first air duct body 211 is simultaneously connected to the wave peak structure 220 of the second air duct body 213 and the wave peak structure 220 of the partition wall 212 at the connection 216. From the appearance, the air duct 200 is in the form of a corrugated tube, and at the same time, the pipeline surrounded by the partition wall 212 and the first air duct body 211 is also in the form of a corrugated tube. Such a configuration can facilitate the expansion and contraction of the air duct 200 as a whole, and also facilitate the processing and manufacturing of the air duct 200.

[0055] Reference Figure 3 , Figure 7 As shown, in some embodiments, at least one reinforcing wire 217 is spirally wound and embedded in the first air duct body 211, the second air duct body 213 and the partition wall 212. By embedding the same reinforcing wire 217 in the first air duct body 211, the second air duct body 213 and the partition wall 212, the air duct 200 can be reinforced with only one reinforcing wire 217. It is expected that multiple reinforcing wires 217 can be provided, such as two, three or more. The reinforcing wire 217 can be made of various suitable materials, including but not limited to metal wires such as steel wire, aluminum wire or copper wire or non-metal wires such as carbon fiber wire. It should also be noted that in the manufacturing process of the air duct 200, the structural frame of the air duct 200, i.e., the structural frame of the first air duct body 211, the second air duct body 213 and the partition wall 212, is firstly spirally wound with a reinforcing wire 217 according to the structure of the air duct 200, and then the air duct 200 is extruded and molded based on the structural frame wound by the reinforcing wire 217. The manufacturing process is simple and efficient, which greatly reduces the manufacturing cost.

[0056] like Figure 7As shown, in some embodiments, the reinforcing wire 217 is repeatedly wound around the outer peripheral wall of the ventilation cavity and the outer peripheral wall of the first air duct 214 in sequence. The reinforcing wire 217 is alternately wound around the outer peripheral wall of the ventilation cavity and the outer peripheral wall of the first air duct 214, which can improve the winding efficiency of the reinforcing wire 217 during the manufacturing process of the air duct 200, and can also greatly improve the strength of the air duct 200. It should be noted that the reinforcing wire 217 can be wound around the outer peripheral wall of the ventilation cavity and the outer peripheral wall of the first air duct 214 in sequence in a circle each time, or can be wound in a circle more than one time, or can be wound around the outer peripheral wall of the ventilation cavity first m circles, and then wound around the outer peripheral wall of the first air duct 214 n circles, wherein m and n are both natural numbers, and m is not equal to n.

[0057] Refer to the following Figure 7 Further describing the reinforcing wire 217, the reinforcing wire 217 includes a spiral structure, the spiral structure includes a three-dimensional outer spiral segment 218 and a three-dimensional inner spiral segment 219, the outer spiral segment 218 is arranged around the outer peripheral wall of the ventilation cavity, and the inner spiral ring segment 219 is arranged around the outer peripheral wall of the first air duct 214, the outer spiral segment 218 and the inner spiral segment 219 are alternately arranged and adjacent outer spiral segments 218 and inner spiral segments 219 are connected. Figure 7 As shown, a spiral segment between A and B is an outer spiral segment 218, and a spiral segment between B and C is an inner spiral segment 219. The outer spiral segment 218 and the inner spiral segment 219 are alternately arranged.

[0058] Reference Fig. 9 As shown, in some embodiments, the wave crest structures 220 of the first air duct body 211 are all embedded with reinforcing wires 217, the wave crest structures 220 of the second air duct body 213 are alternately embedded with reinforcing wires 217, and the wave crest structures 220 of the partition wall 212 are alternately embedded with reinforcing wires 217, wherein the reinforcing wires 217 of the second air duct body 213 and the reinforcing wires 217 of the partition wall 212 are staggeredly arranged along the extension direction of the second air duct 215. The above arrangement enables the reinforcing wires 217 to be repeatedly wound around the outer peripheral wall of the ventilation cavity and the outer peripheral wall of the first air duct 214 in a circle each time, thereby achieving overall reinforcement of the air duct 200 and facilitating extrusion molding of the air duct 200. By arranging the reinforcing wire 217 at the peak structure 220, i.e., at the outer edge, the outer edge of the first air duct 214 and the outer edge of the ventilation cavity can be reinforced and shaped to prevent the air duct from abnormally deforming at the outer edge of the first air duct 214 and the outer edge of the ventilation cavity, thereby affecting the expansion and contraction. At the same time, it is also helpful to obtain an air duct 200 with a cross-section of any shape to meet usage requirements and optimize the appearance.

[0059] Reference Fig.10As shown, in some embodiments, the wave crest structures 220 of the first air duct body 211 are all embedded with reinforcing wires 217, and the wave crest structures 220 of the second air duct body 213 are all embedded with reinforcing wires 217. The reinforcing wires 217 of the first air duct body 211 and the reinforcing wires 217 of the second air duct body 213 are sequentially connected along the extension direction of the second air duct 215 and are distributed in a spiral shape. By embedding the reinforcing wires 217 in the wave crest structures 220 of the first air duct body 211 and the second air duct body 213, the outer peripheral wall of the ventilation cavity is strengthened, so that the outer peripheral wall of the ventilation cavity can be roughly fixed in shape, so as to facilitate expansion and contraction. It can be expected that when the wave crest structures 220 of the first air duct body 211 and the second air duct body 213 are embedded with reinforcing wires 217, the partition wall 212 can be embedded with reinforcing wires 217 in any form described in the present invention or in other suitable forms, or may not be embedded with reinforcing wires 217.

[0060] Reference Fig.11 As shown, in some embodiments, the wave crest structures 220 of the first air duct body 211 are all embedded with reinforcing wires 217, and the wave crest structures 220 of the partition walls 212 are all embedded with reinforcing wires 217. The reinforcing wires 217 of the first air duct body 211 and the reinforcing wires 217 of the partition walls 212 are sequentially connected along the extension direction of the first air duct 214 and are distributed in a spiral shape. The outer peripheral wall of the first air duct 214 is reinforced by embedding the reinforcing wires 217 in the wave crest structures 220 of the first air duct body 211 and the partition walls 212. It can be expected that when the reinforcing wires 217 are embedded in the wave crest structures 220 of the first air duct body 211 and the partition walls 212, the reinforcing wires 217 may be embedded in the second air duct body 213 in any form described in the present invention or in other suitable forms, or may not be embedded in the reinforcing wires 217.

[0061] In some embodiments, the thickness of at least part of the wave crest structure 220 of the air duct 200 is greater than the thickness of other parts of the air duct 200. By thickening the wave crest structure 220, the air duct 200 can be strengthened at these thickened wave crest structures 220, so that the shape of the air duct 200 at these positions is roughly fixed, thereby facilitating expansion and contraction. It is understandable that a reinforcing wire 217 can be set in the thickened wave crest structure 220, so as to further strengthen it.

[0062] In some embodiments, the thickness of the peak structure 220 of the first air duct body 211 and the thickness of the peak structure 220 of the second air duct body 213 are both greater than the thickness of other parts of the air duct 200. The outer peripheral wall of the ventilation cavity is strengthened by thickening the peak structure 220 of the first air duct body 211 and the second air duct body 213. In the case where the peak structure 220 of the first air duct body 211 and the second air duct body 213 is thickened, the peak structure 220 of the partition wall 212 can also be thickened, or not, and of course, the reinforcing wire 217 can be embedded in any form described in the present invention or in other suitable forms, or the reinforcing wire 217 can also be not embedded.

[0063] In some embodiments, the thickness of the peak structure 220 of the first air duct body 211 and the thickness of the peak structure 220 of the partition wall 212 are greater than the thickness of other parts of the air duct 200. The outer peripheral wall of the first air duct 214 is strengthened by thickening the peak structure 220 of the first air duct body 211 and the partition wall 212. In the case where the peak structure 220 of the first air duct body 211 and the partition wall 212 is thickened, the peak structure 220 of the second air duct body 213 can also be thickened, or not, and of course, the reinforcing wire 217 can be embedded in any form described in the present invention or in other suitable forms, or the reinforcing wire 217 can be not embedded.

[0064] The thickness of the aforementioned thickened peak structure 220 can be any thickness in the range of 0.5mm-2mm, and of course can also be set to other suitable thicknesses as needed. Setting the thickness of the peak structure 220 to 0.5mm-2mm can make the peak structure 220 thicker than other parts of the air duct 200 in most cases, thereby achieving a strengthening effect. Figure 2 As shown, the air intake and exhaust structure according to the second embodiment of the present invention includes the air duct 200 of the first embodiment of the present invention, and is further provided with a joint assembly 300 connected to the air duct 200. By providing the joint assembly 300, the air duct 200 can be installed on other structures such as windows, so that the air duct 200 can exhaust air to the outside or absorb air from the outside.

[0065] Reference Figure 2 , Figure 8 , Fig. 9 As shown, in some embodiments, the joint assembly 300 includes a joint base 310, a swivel joint 320, and a connecting pipe 340. One end of the joint base 310 is connected to the air duct 200, and the swivel joint 320 is rotatably connected to the other end of the joint base 310. By providing a rotatable swivel joint 320 on the joint assembly 300, the joint assembly 300 is suitable for both horizontal and vertical installations, and can also be suitable for installations in other directions, and can be applicable to windows or other components of various shapes and directions. Fig.12As shown, the window 400 has a transverse through hole 401. At this time, the rotating head 320 on the joint assembly 300 rotates to make it fit with the through hole 401, and only the air duct 200 needs to be stretched without twisting the air duct 200. Similarly, as shown in FIG. Fig.13 As shown, the window 400 has a longitudinal through hole 401 , and at this time, the rotating head 320 on the joint assembly 300 is rotated to make it fit with the through hole 401 , and the air duct 200 only needs to be stretched and twisted.

[0066] Reference Figure 2 As shown, in some embodiments, a pipe joint 315 is provided on the joint seat 310, and two mutually separated first air duct holes (not shown) and a second air duct hole 313 are provided on the pipe joint 315. The shape of one end of the joint seat 310 is adapted to the shape of the air duct 200, and one end of the joint seat 310 is also provided with a first clamp 311 and a second clamp 312 for clamping in the first air duct 214 and the second air duct 215, respectively. During installation, the first clamp 311 and the second clamp 312 are clamped in the first air duct 214 and the second air duct 215, respectively, at which time the first air duct 214 is aligned with the first air duct hole, and the second air duct 215 is aligned with the second air duct hole 313.

[0067] Reference Figure 2 As shown, in some embodiments, the other end of the joint seat 310 has a circular hole 314, and the end of the rotary joint 320 close to the joint seat 310 is provided with a circular seat 324. The circular seat 324 is adapted to the circular hole 314 and the circular seat 324 can rotate in the circular hole 314, so that the rotary joint 320 can rotate on the joint seat 310.

[0068] Reference Figure 2 As shown, one end of the connecting pipe 340 is connected to the joint assembly 310 and communicates with the first air duct 214.
