[0025] An air compressor for producing a foaming agent, comprising:

[0026] An air compressor 1 and a noise reduction mechanism 2, wherein the noise reduction mechanism 2 is arranged on the outside of the air compressor 1, and the noise reduction mechanism 2 is used to reduce the noise generated by the air compressor 1 in a running state; the noise reduction mechanism 2 includes a noise reduction box 201, an L-shaped movable frame 202, a noise reduction plate assembly and a driving assembly; the noise reduction box 201 is used to isolate the air compressor 1 from the outside, and the L-shaped movable frame 202 is used to place the air compressor 1; the driving assembly is used to drive the L-shaped movable frame 202 to move; the noise reduction plate assembly is used to reduce the noise generated by the air compressor 1 in a running state;

[0027] The driving assembly includes a T-shaped piece 205, a T-shaped slot 206, a motor 207 and a screw rod 208; the T-shaped slot 206 is opened at the bottom of the inner wall of the noise reduction box 201, the T-shaped piece 205 is slidably connected to the inside of the T-shaped slot 206, and the T-shaped piece 205 is fixedly connected to the bottom end of the horizontal part of the L-shaped moving frame 202, the motor 207 is installed on the outer wall of the noise reduction box 201, the screw rod 208 is fixedly connected to the end of the output shaft of the motor 207, and the screw rod 208 is connected to the L-shaped moving frame 202 through a screw rod seat;

[0028] The noise reduction plate assembly includes a noise reduction plate 203, a through hole 204, sound-absorbing glass wool 209 and a sound insulation and shock-absorbing pad 2010; the noise reduction plate 203 is installed on the inner wall of the noise reduction box 201 and the inner side of the vertical part of the L-shaped movable frame 202, and the noise reduction plate 203 is a hollow structure. The through hole 204 is opened on the outer side of the noise reduction plate 203 and penetrates into the interior thereof, and the sound-absorbing glass wool 209 and the sound insulation and shock-absorbing pad 2010 are both arranged in the inner cavity of the noise reduction plate 203.

[0029] In one embodiment, the L-shaped movable frame 202 moves axially inside the noise reduction box 201 and extends outside thereof, and a transparent observation window 3 is provided on the outer side of the vertical portion of the L-shaped movable frame 202 .

[0030] In one preferred embodiment, the output shaft of the motor 207 in the running state is used to drive the screw rod 208 to rotate, and the screw rod 208 in the rotating state is used to drive the L-shaped moving frame 202 to move.

[0031] In one embodiment, the sound-absorbing glass wool 209 and the sound-insulating and shock-absorbing pad 2010 are used to improve the noise reduction effect, and the sound-absorbing glass wool 209 and the sound-insulating and shock-absorbing pad 2010 are connected by adhesive.

The noise generated by the operation of the air compressor 1 enters the noise reduction plate 203 through multiple through holes 204 and is reflected inside the sound-absorbing glass wool 209 and the sound insulation and shock absorption pad 2010 until the energy of the sound waves is consumed and converted into heat energy.
