[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, this embodiment provides a sound-absorbing louver air vent, including a basic frame 1, louvers 2, a frame 3, a first sound-absorbing sponge 4, a noise reduction plate 5, and a second sound-absorbing sponge 6. The frame 3 is mounted inside the basic frame 1, and a plurality of louvers 2 are hingedly mounted on the frame 3. The first sound-absorbing sponge 4 and the second sound-absorbing sponge 6 are respectively attached to both sides of the noise reduction plate 5. A plurality of noise reduction channels 51 are provided inside the noise reduction plate 5, and the noise reduction channels 51 are in the shape of a cross. Figure 1 The left side of the basic frame 1 is the air outlet, and the right side of the basic frame 1 is the air inlet.

[0022] Furthermore, the thickness of the first silencer sponge 4 and the second silencer sponge 6 is 2-5 cm, with 3 cm being preferred. Of course, the specific thickness of the silencer sponge is flexibly selected according to the use requirements. A silencer sponge with a thickness of 3 cm is commonly selected for air vents with low noise.

[0023] Furthermore, the first sound-absorbing sponge 4 and the second sound-absorbing sponge 6 are located on the inner side of the louver 2, with a double-layer design. The first sound-absorbing sponge 4 and the second sound-absorbing sponge 6 are superimposed on both sides of the noise reduction plate 5 to form a composite sound-absorbing structure, which is beneficial to improving the noise reduction effect.

[0024] Taking the sound-absorbing louver 2 air outlet in this embodiment as an example, the noise is first reduced by the first sound-absorbing sponge 4, then by the cross-shaped noise reduction channel 51 on the noise reduction plate 5, and finally by the second sound-absorbing sponge 6. The multiple structures reduce noise, effectively ensuring the overall noise reduction and noise reduction effect of the sound-absorbing louver air outlet.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, this embodiment provides a sound-absorbing louver air vent. The difference between this embodiment and embodiment 1 is that the connectivity between the base frame 1 and the installation port is improved during and after the installation of the louver air vent, thereby improving the auxiliary installation effect. Specifically, an elastic block 11 is provided on the base frame 1, and a spring groove 12 is integrally formed on the base frame 1. A spring 13 is provided on the inner side of the elastic block 11, and the spring 13 is installed in the spring groove 12. The elastic force of the spring 13 is used to make the elastic block 11 contact and fit with the installation port. A limiting foot 111 is provided at the side end of the elastic block 11 to prevent the elastic block 11 from moving out of the spring groove 12. A sliding port 121 that slides with the limiting foot 111 is provided on the base frame 1, and the displacement distance of the elastic block 11 is the depth of the sliding port 121. The sliding port 121 limits the distance that the elastic block 11 is pushed out by the spring 13, and limits the distance that the elastic block 11 is forced to retract inward.

[0027] Compared with the traditional louver 2 frame which directly adopts the entire side to fit the installation port, the elastic block 11 set on the base frame 1 of the louver 2 in this embodiment effectively improves the connection effect of the base frame 1 installed to the installation port, and achieves a similar clamping effect through the elastic block 11, thereby improving the installation stability.
