[0031] In order to solve various problems in the prior art, the present application provides a novel two-in-one through-the-wall air duct, that is, the interior of the air duct is divided into at least two flow channels, which can meet the needs of exhaust and air intake at the same time, and can also meet the installation and use on walls with different wall thicknesses. The through-the-wall air duct of the present application is made of SAS polymer material that is anti-ultraviolet and anti-aging, so it can meet the use requirements in the sun, rain, high temperature and high humidity environment.

Figure 7 is an overall view of a through-wall air duct according to an exemplary embodiment of the present disclosure. Figure 8 FIG. 4 is an overall view of a through-wall air duct according to an exemplary embodiment of the present disclosure from another angle.

[0033] like Figure 1 , Figure 5 , Figure 6 As shown, in one embodiment of the present application, the through-wall air duct 1 includes: a fixing base 10, fixed to the wall, for fixing and adjusting the length of the through-wall air duct 1 inside and outside the wall; an air duct body 20, the air duct body penetrates the wall 70 and is fixed to the wall 70 through the fixing base 10, the air duct body 20 is a hollow pipe, the hollow pipe is divided into at least two channels along the axial direction of the pipe, and at least two vents are provided at two opposite ends of the air duct body 20, one of the at least two vents is an air inlet, and the other is an air outlet.

[0034] In one embodiment of the present application, Figure 1 , Figure 5 , Figure 6 Figure 7 and Figure 8 As shown, the fixing seat 10 can be presented as a frame structure, and an opening matching the external shape of the air duct body is opened in the middle of the rectangular plate structure 11 to allow the air duct body to pass through. A section 12 matching the external shape of the air duct body is extended along a direction perpendicular to the middle opening, that is, along the axial direction of the air duct body. For example, when the air duct body is a circular tube, the section is a circular tube, and when the air duct body is a polygonal column, the section is also a polygonal column, so that the air duct body is more firmly fixed to the fixing seat 10, and then fixed relative to the wall.

[0035] The four corners of the rectangular plate-like structure 11 may be equipped with fixings for fixing to the wall, such as bolts. A circle of protrusions is provided above the opening of the rectangular plate-like structure 11, and an adjustment hole is provided on the protrusion. An adjustment member for adjusting the length of the air duct body inside and outside the wall passes through the adjustment hole and is fixed to the air duct body. In one example, the adjustment member 13 may be a handle screw. In other examples, the adjustment member 13 may be a bolt or other reusable clamping member.

[0036] The fixing seat 10 may be an integrated metal component, or may be assembled from a plurality of metal components. In other examples, the fixing seat may also be a plastic component or be made of other materials.

[0037] In one embodiment of the present application, Figure 2-4 As shown, the air duct body 20 is a hollow tubular member, and the gas flows in the hollow interior. The hollow interior is divided into a plurality of longitudinal spaces along the axis of the tube to allow multiple airflows to flow therein at the same time, or a kind of airflow flows in the separated spaces along different directions. In one example, as shown in the figure, the air duct body 20 is divided into two ventilation ducts by a partition along the axial direction of the tube. Thus, two vents are formed correspondingly at both ends of the air duct body. In this example, the partition directly extends to the two ends of the air duct body 20, so that two vents are directly formed at the end. In this embodiment of the present application, the two ventilation ducts can be formed as an air inlet duct and an air outlet duct, respectively.

[0038] The air duct body 20 can be made of SAS polymer material that is UV-resistant and anti-aging, so that the through-the-wall air duct is not afraid of sun and rain, and can also be used for a long time in a high temperature and high humidity environment.

[0039] The outside of the duct body 20 can be marked with fixed lengths to intuitively determine the length of the duct body 20 inside and outside the wall. The air intake direction or other available marks can also be marked on the outside of the duct body 20. For example, the outdoor wall line, the 25CM thick wall installation line, and the 50CM thick wall installation line can be engraved on the outer surface of the duct body 20, so as to facilitate visual adjustment of the length of the duct body 20 inside and outside the wall according to walls of different thicknesses or to obtain the appropriate length of the duct body 20.

[0040] In one embodiment of the present application, the number of channels in the air duct body 20 is the same as the number of vents provided at each end of the air duct body 20. That is, the air duct body can be formed into three ventilation ducts by the partition, and correspondingly, three vents are formed at each end of the air duct body. For example, four ventilation ducts are formed in the air duct body, and correspondingly, four vents are formed at each end of the air duct body.

[0041] In one embodiment of the present application, the through-wall air duct 1 further includes a Y-shaped flow guide head, which is installed on the inner side of the wall so as to more conveniently connect with fresh air equipment, bathroom heater or other ventilation equipment. For example, the end of the through-wall air duct 1 inside the wall is called the first end, and the Y-shaped flow guide head is installed at the first end of the through-wall air duct 1. When the inside of the air duct body 20 is divided into two channels, the Y-shaped flow guide head also includes two vents accordingly. In other embodiments, the Y-shaped flow guide head may include two vents.

[0042] In one embodiment of the present application, Figure 1-8 The number of vents provided in the Y-shaped guide head is the same as the number of channels in the air duct body 20. That is, the air duct body can be formed into three ventilation ducts by the partition, and correspondingly, three vents are formed in the Y-shaped guide head. For example, four ventilation ducts are formed in the air duct body, and correspondingly, four vents are formed in the Y-shaped guide head.

[0043] In one embodiment of the present application, the air duct body 20 is divided into two channels along the axial direction of the duct, one channel is an air inlet channel 23, and the other channel is an air exhaust channel 24. Alternatively, the air duct body is formed into three ventilation ducts along the axis of the tube by a partition, one air inlet channel, and two air exhaust channels. Alternatively, the air duct body is formed into three ventilation ducts along the axis of the tube by a partition, two air inlet channels, and one air exhaust channel. Alternatively, the air duct body is formed into four ventilation ducts along the axis of the tube by a partition, two air inlet channels, and two air exhaust channels.

[0044] In one embodiment of the present application, when the air duct body is divided into two channels along the axial direction of the duct, one channel is the air inlet channel 31, and the other channel is the air exhaust channel 32, the ratio of the cross section of the air inlet channel to the cross section of the air exhaust channel can be 4:6. At this time, the area ratio of the two vents in the Y-shaped guide head is also 4:6.

[0045] In other examples, the ratio of the cross-section of the air inlet channel 23 to the cross-section of the air exhaust channel 24 may be 5:5. In this case, the area ratio of the two vents in the Y-shaped guide head is also 5:5. Alternatively, the ratio of the cross-section of the air inlet channel to the cross-section of the air exhaust channel may be 6:4. In this case, the area ratio of the two vents in the Y-shaped guide head is also 6:4. Alternatively, the ratio of the cross-section of the air inlet channel to the cross-section of the air exhaust channel may be 3:7. In this case, the area ratio of the two vents in the Y-shaped guide head is also 3:7.

[0046] In one embodiment of the present application, the second end of the air duct body 20 is arranged outside the wall, and an exhaust port 22 is arranged at the second end, and the exhaust port 22 is arranged at the end of the air duct body 20. A shutter-type waterproof member 40 is arranged at the exhaust port 22, so as to effectively prevent rainwater from flowing back.

[0047] In one embodiment of the present application, the air inlet 21 at the second end of the air duct body 20 can be set on the side wall of the air duct body 20, and the air inlet 21 can be a notch on the air duct body. Preferably, a grille can be provided on the notch to prevent debris from entering the ventilation duct.

[0048] In other examples, the air outlet at the second end of the air duct body can be arranged on the side wall of the air duct body, and the air inlet is arranged at the end of the air duct body. The air outlet can be a notch on the circular tube, or a grille can be arranged on the notch.
