[0031] The embodiment of the present invention discloses a novel air supply outlet device, wherein the pipe body cooperates with an adjustable shrinking pipe to supply air, so that a part of the airflow transported by the throat pipe of the pipe body enters the expanding pipe of the pipe body to increase the air supply range, and the other part enters the shrinking pipe, the wind speed gradually increases, and the air supply range is increased, which not only meets the requirements of tall buildings for the air supply range, but also increases the air supply range and is easy to use. The embodiment of the present invention also discloses an air supply system using the novel air supply outlet device, which not only has a long air supply range, but also a wide air supply range, and is suitable for tall buildings.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 4The embodiment of the present invention provides a new type of air supply outlet device, including a tube body and a shrinking tube 2; the tube body includes a throat 4 and an expanding tube 1 that are interconnected, the first end of the expanding tube 1 is fixedly connected to the throat 4, and the flow area of ​​the expanding tube 1 gradually increases from the first end to the second end of the expanding tube 1; the flow area of ​​the shrinking tube 2 gradually decreases from the first end to the second end of the shrinking tube 2; wherein the shrinking tube 2 is installed in the tube body; the first end of the shrinking tube 2 is close to the throat 4, the second end is away from the throat 4, and the axial installation position of the shrinking tube 2 in the expanding tube 1 is adjustable.

[0034] In the novel air outlet device provided in this embodiment, the pipe body cooperates with the shrinking pipe 2 to realize air supply, so that part of the airflow transported by the throat pipe 4 of the pipe body enters the expanding pipe 1 of the pipe body, increasing the air supply range, and the other part enters the shrinking pipe 2. The flow area of ​​the shrinking pipe 2 gradually decreases, so that the wind speed gradually increases and the air supply range is increased. Obviously, the novel air outlet device provided in this embodiment not only meets the requirements of tall buildings for air supply range, but also increases the air supply range and is easy to use.

[0035] In addition, in the new air supply port device provided in the present embodiment, the axial installation position of the contracting tube 2 in the tube body is adjustable. During use, the flow area ratio of the contracting tube 2 and the expanding tube 1 can be adjusted by adjusting the axial installation position of the contracting tube 2 in the tube body, thereby adjusting the flow state of the air supply. Compared with the existing new air supply port devices, the adjustment range of the air supply flow state is wide; in addition, as the flow area ratio changes, the local resistance coefficient of the air port also changes, thereby also playing a certain regulatory role on the air supply flow rate.

[0036] In addition, the new air supply outlet device provided in this embodiment has a large range and a large air supply range, thereby avoiding the limitation of the installation position of the new air supply outlet device due to the air supply range or range requirements of the building.

[0037] In the above-mentioned new air supply outlet device, the shrinking tube 2 can be positioned at multiple preset axial installation positions in the tube body, which not only improves the air supply flow adjustment range, but also ensures that the shrinking tube 2 can be maintained at a certain preset axial installation position according to usage needs, thereby avoiding the shrinking tube 2 from being displaced by the airflow.

[0038] Specifically, in the above-mentioned novel air outlet device, the shrinking tube 2 is installed on the inner wall of the throat tube 4 or the expanding tube 1 through the telescopic rod 3. One end of the telescopic rod 3 can be welded or plugged into the inner wall of the tube body, and this embodiment does not limit the method of fixing the telescopic rod and the tube body. The other end of the telescopic rod 3 can also be set to be fixedly connected to the shrinking tube 2 by welding, plugging, connecting with a fixing piece, etc., and this embodiment does not limit it.

[0039] The number of sections in the telescopic rod 3 is the same as the number of preset axial installation positions, and each section corresponds to a preset axial installation position.

[0040] In order to prevent the telescopic rod from automatically deviating in the direction of the airflow when the wind speed is high, in any two adjacent sections of the telescopic rod 3, the first section 31 can extend the second section 32 in the direction away from the throat 4; the end of the first section 31 is provided with a convex edge for cooperating with a stopper at the opening of the second section 32 to prevent the end of the first section 31 from slipping out of the opening of the second structure 32. Figure 2 When the convex edge of the first section rod 31 abuts against the stopper of the second section rod 32, the shrink tube 2 is at a preset axial installation position.

[0041] In the above-mentioned novel air outlet device, when the shrinking tube 2 is in the initial preset axial installation position, the first end of the shrinking tube 2 can be located at the connection between the throat pipe 4 and the expanding tube 2, such as Figure 3 As shown, or the first end of the shrinking tube 2 is in the throat 4, which is not limited in this embodiment. When the shrinking tube 2 is at the end of the preset axial installation position, the first end of the shrinking tube 2 is in the expanding tube 1 and the second end is outside the expanding tube 1, such as Figure 4 As shown, either the first end and the second end of the shrinking tube 2 are both outside the expanding tube 1, or the first end and the second end of the shrinking tube 2 are both inside the expanding tube 1, which is not limited in this embodiment.

[0042] The number of telescopic rods 3 can be arranged according to the weight of the shrinking tube 2, and the telescopic rods 3 need to ensure that the shrinking tube 2 is coaxial with the expanding tube 1. Specifically, there are multiple telescopic rods 3, and the telescopic rods 3 are evenly distributed along the circumference of the shrinking tube 2.

[0043] In the above air supply device, the expanded tube 1 is a bell-mouth type, and the flow area gradually increases along the air flow direction. Preferably, the outer shell of the expanded tube 1 is an arc-shaped curved surface, which not only increases the air supply range, but also plays a role in noise reduction.

[0044] In the novel air outlet device provided in the above embodiment, the shrinking pipe 2 is a conical pipe, and 2s+d≤D, wherein d is the inner diameter at the first end of the shrinking pipe 2, s is the wall thickness of the shrinking pipe 2, and D is the inner diameter of the throat pipe 4. In this embodiment, 2s+d≤D can further increase the flow pattern adjustment range.

[0045] In order to adjust the flow rate of the novel air outlet device, in the above embodiment, a valve plate 5 for adjusting the flow area is provided in the throat pipe 4. Further, the valve plate 5 has a closed state, in which the flow area of ​​the throat pipe 4 is 0, and acts as an isolation valve.

[0046] The valve plate 5 is fixed to the valve plate shaft 6, which is mounted on the throat 4 so as to be rotatable around its own axis, and the valve plate shaft 6 is connected to an actuator 7. The actuator 7 can be set as a handle fixedly connected to the valve plate shaft 6, or as a motor for driving the valve plate shaft 4 to rotate, etc., and the present embodiment does not limit the type of the actuator 7.

[0047] Preferably, in the above-mentioned novel air supply port device, the throat pipe 4, the expanding pipe 1 and the shrinking pipe 2 are coaxial.

[0048] The present invention also provides an air supply system, including a novel air supply outlet device, and the novel air supply outlet device is the novel air supply outlet device provided in the above embodiment.

[0049] The air supply system uses the novel air supply outlet device provided by the above embodiment, which not only has a long air supply range, but also a wide air supply range, and is suitable for tall buildings. Of course, the air supply system provided by this embodiment also has other effects of the novel air supply outlet device provided by the above embodiment, which will not be repeated here.

[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
