[0020] The embodiment of this application discloses an air-conditioning louver air outlet with a sound insulation effect. By means of the transverse blades 20 and longitudinal blades 30 with different inclination angles, in cooperation with the first sound insulation holes 40 and the second sound insulation holes 50 on the transverse blades 20 and longitudinal blades 30, the rebounding direction of sound is changed to sound-insulate the noise.

[0021] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0022] Please refer to Figures 1 - 4 , this embodiment provides an air-conditioning louver air outlet with a sound insulation effect, which includes an outer frame 10. A plurality of horizontal vanes 20 are horizontally arranged inside the outer frame 10, and the inclination angles of adjacent two horizontal vanes 20 are different. A plurality of vertical vanes 30 are longitudinally arranged inside the outer frame 10, and the inclination angles of adjacent two vertical vanes 30 are different. A plurality of first sound insulation holes 40 are opened at the tops of the plurality of horizontal vanes 20, and the plurality of first sound insulation holes 40 are arranged equidistantly and parallelly on the horizontal vanes 20. A plurality of second sound insulation holes 50 are opened at the tops of the plurality of vertical vanes 30, and the plurality of second sound insulation holes 50 are arranged equidistantly and parallelly on the vertical vanes 30. Through the adjacent horizontally arranged horizontal vanes 20 and vertical vanes 30, when sound enters between the plurality of horizontal vanes 20 and vertical vanes 30, the reflection angle can be changed, so that sound waves cancel each other out during propagation, achieving the purpose of noise reduction. Through the plurality of first sound insulation holes 40 and second sound insulation holes 50 on the horizontal vanes 20 and vertical vanes 30, sound waves enter the interior of the pores, and multiple reflections and diffractions occur in the pores, consuming sound energy, thereby achieving the purpose of sound absorption.

[0023] Please refer to Figures 1 - 4 , a sound insulation component 60 is arranged on the inner wall of the outer frame 10. Horizontal clamping grooves 70 are opened at the top and bottom of the inner wall of the outer frame 10, and longitudinal clamping grooves 80 are opened on both sides of the outer frame 10. The sound insulation component 60 includes a sound insulation pad 61, horizontal clamping blocks 62, longitudinal clamping blocks 63, a sound insulation seat 64, a sound insulation block 65, a fixed clamping groove 66, and a fixed clamping block 67. The sound insulation pad 61 is detachably arranged on the inner wall of the outer frame 10. Through holes for fixing the horizontal vanes 20 and vertical vanes 30 are opened on the sound insulation pad 61. Two horizontal clamping blocks 62 are arranged at the top and bottom of the sound insulation pad 61, and two longitudinal clamping blocks 63 are arranged on both sides of the sound insulation pad 61. The horizontal clamping blocks 62 are engaged with the horizontal clamping grooves 70, and the longitudinal clamping blocks 63 are engaged with the longitudinal clamping grooves 80. By engaging the two horizontal clamping blocks 62 and two longitudinal clamping blocks 63 on the sound insulation pad 61 into the horizontal clamping grooves 70 and longitudinal clamping grooves 80 on the inner wall of the outer frame 10, the sound insulation pad 61 can be installed on the inner wall of the outer frame 10. The material of the sound insulation pad 61 is sound insulation cotton. The porous structure inside the sound insulation pad 61 can enable sound waves to enter the material interior, and convert sound energy into heat energy through the friction between air molecules and the pore walls, absorbing the energy of sound waves, thereby reducing the reflection and propagation of sound and achieving the effect of noise reduction.

[0024] Please refer to Figures 1 - 5, four sound-absorbing seats 64 are respectively arranged at the four corners of the sound-absorbing pad 61, a plurality of sound-absorbing blocks 65 are arranged on the inclined surfaces of the four sound-absorbing seats 64, and the plurality of sound-absorbing blocks 65 are arranged at equal intervals on the inclined surfaces of the sound-absorbing seats 64. Two fixed card slots 66 are opened on both sides of the corners of the sound-absorbing pad 61, and fixed card blocks 67 are fixedly arranged on both sides of the sound-absorbing seats 64. The fixed card blocks 67 are engaged inside the fixed card slots 66. The sound-absorbing seats 64 and the sound-absorbing blocks 65 are made of sound-absorbing cotton. Through the sound-absorbing seats 64 and the sound-absorbing blocks 65 filled at the corners, the sound waves are absorbed and reflected at the turning, and the energy of the sound waves is converted into the energy of the oblique waves when turning and is effectively absorbed by the sound-absorbing material, achieving the sound-absorbing effect.

[0025] The functional principle of the present application can be elaborated through the following operation methods:

[0026] During use, the sound-absorbing pad 61 is placed on the inner wall of the outer frame 10. The horizontal card blocks 62 at the top and bottom of the sound-absorbing pad 61 are installed and engaged inside the horizontal card slots 70, and the vertical card blocks 63 on both sides of the sound-absorbing pad 61 are installed and engaged inside the vertical card slots 80, so that the sound-absorbing pad 61 is installed on the inner wall of the outer frame 10. Then, the four sound-absorbing seats 64 are placed at the corners of the sound-absorbing pad 61, so that the fixed card blocks 67 on both sides of the sound-absorbing seats 64 are installed and engaged inside the fixed card slots 66 on the side of the sound-absorbing pad 61, so that the sound-absorbing seats 64 are fixed at the corners of the sound-absorbing pad 61. Then, the horizontal blades 20 and the vertical blades 30 are installed inside the outer frame 10. The adjacent horizontal blades 20 and vertical blades 30 with different inclination angles can change the rebound angle of the sound, and cooperate with the multiple first sound-absorbing holes 40 and second sound-absorbing holes 50 opened on the horizontal blades 20 and the vertical blades 30 to absorb the sound. When the noise in the air duct rebounds into the sound-absorbing pad 61 at the position of the inner wall of the outer frame 10, the porous structure inside the sound-absorbing pad 61 can convert the sound energy into heat energy through the friction between the air molecules and the pore walls, absorbing the energy of the sound waves. The sound-absorbing seats 64 and the sound-absorbing blocks 65 filled at the corners make the sound waves be absorbed and reflected at the turning, and the energy of the sound waves is converted into the energy of the oblique waves when turning and is effectively absorbed by the sound-absorbing material, achieving the sound-absorbing effect.
