[0002] The full air system generally adopts the way of centralized return air, and each room served by the full air system is a relatively closed space after the door is closed, so the centralized return air of the full air system needs to rely on the connection channel connecting different spaces, but the connection channel will affect the sound insulation effect and cause the problem of light leakage, which causes the trouble of the privacy and living comfort of the consumer. Figure 1 For example, the centralized return air port is arranged in the second space A, the first space B is adjacent to the second space A, a connection hole C1 is arranged on the wall C between the first space B and the second space A, and the air in the first space B is input into the second space A through the connection hole C1. Figure 1 Compared with the more beautiful structure, the problem of light leakage and poor sound insulation caused by the existence of the connection channel cannot be well solved by the existing connection structure. UTILITY MODEL CONTENT

[0003] The utility model solves the technical problem that a new air connection structure is provided, and the problem of light leakage and poor sound insulation caused by the existence of the connection channel is obviously improved.

[0005] The air can flow into the air connection box from the first space through the air inlet, and then flow into the second space from the air connection box through the air outlet, so as to complete the return air from the first space to the second space. Since the air connection box is assembled by the black sound-absorbing plates, the light absorption structure and the impedance composite sound absorption structure are formed, the air connection box has the functions of sound absorption and light absorption, and the problem of light leakage and poor sound insulation caused by the existence of the connection channel can be obviously improved.

[0019] This embodiment provides an air communication box, see [link]. Figure 2 and 3 The air communication box 100 consists of a main box 101, an air inlet box 102, and an air outlet box 103. All three boxes are rectangular structures assembled from multiple black sound-absorbing panels. The air inlet box 102 and the air outlet box 103 are located below the main box 101. The upper sides of the air inlet box 102 and the air outlet box 103 are fixedly connected to the main box 101. The lower side of the air inlet box 102 has an air inlet 1, and the lower side of the air outlet box 103 has an air outlet 2.

[0020] The main housing 101 has an air inlet corresponding to the air inlet box 102 and an air outlet corresponding to the air outlet box 103 on its lower side. The air inlet box 102 has a first connecting port on its upper side, and the air outlet box 103 has a second connecting port on its upper side. The air inlet connecting port is located within the range of the first connecting port, and the air outlet connecting port is located within the range of the second connecting port. The air inlet connecting port is smaller than the first connecting port and is positioned to the right of the first connecting port, forming a first wind deflector S1 on the lower left side of the main housing 101. The first wind deflector S1 blocks the first connecting port, improving the noise reduction effect. The air outlet 2 has an area of ​​50% to 80% of the lower area of ​​the air outlet box 103. By reducing the size of the air outlet, the noise reduction effect is improved. (See [reference needed]). Figure 2 The air outlet 2 is formed by opening on the lower side of the air outlet box 103. The area of ​​the air outlet 2 is smaller than the area of ​​the lower side of the air outlet box 103, so that a second baffle S2 is formed on the left and right sides of the air outlet 2.

[0021] In order to improve the noise reduction effect, the air communication box can be designed such that the air outlet communication port is smaller than the second communication port, the lower side of the main box blocks the first communication port, and the air inlet port is reduced to 50% to 80% of the area of the lower side of the air inlet box.

[0022] The main box 101 includes a main cavity D1 and an auxiliary cavity D2. The auxiliary cavity D2 is in communication with the main cavity D1 and is located on the front side of the main cavity D1. Compared with the air inlet port 1, the auxiliary cavity D2 is closer to the air outlet port 2. The auxiliary cavity D2 is staggered with the channel directly communicating with the air inlet port 1 and the air outlet port 2. The return air is filled into the auxiliary cavity D2 before flowing out of the air outlet port 2, and is buffered in the auxiliary cavity D2, which can effectively improve the low-frequency noise reduction of the air communication box 100 and reduce the air resistance.

The wall C separates the first space B and the second space A. The first ceiling B1 is arranged in the first space B, and the second ceiling A1 is arranged in the second space A. The wall C is provided with a mounting hole matched with the air communication box 100, and the air communication box 100 is arranged in the mounting hole.

[0024] The first ceiling B1 is provided with a first clearance opening corresponding to the end face of the air inlet port 1, and the second ceiling A1 is provided with a second clearance opening corresponding to the end face of the air outlet port 2. The air communication box 100 significantly weakens the sound propagation between the first space B and the second space A by using the impedance composite sound absorption principle. Since the air communication box 100 has two right-angle bending parts, light cannot enter the second space A from the first space B through the air communication box 100, and light cannot enter the first space B from the second space A through the air communication box 100.
