[0033] The muffling mechanism 8 comprises a muffling box 801, the inside of the muffling box 801 is provided with a cavity 805, the inside of the cavity 805 is filled with sound-absorbing cotton, the two sides of the muffling box 801 are connected with the air inlet 901 through the plug-in interface 802, the bottom of the muffling box 801 is provided with a plurality of through slots 806, the top of the muffling box 801 is provided with a cover plate 807, the muffling box 801 is arranged between the two groups of compression boxes 6, and the muffling box 801 is stably connected with the air compressor head by the bolt and the mounting lug 803. Meanwhile, the air pipe 902 is accurately clamped in the groove 804, and is tightly connected with the air inlet 901 through the plug-in interface 802, thereby forming an efficient muffling mechanism 8, simplifying the complex structure of the traditional muffler, and significantly improving the convenience of maintenance. When the air compressor head is operating, the external air flows into the cavity 805 through the through slots 806, and is subjected to effective noise reduction treatment by the sound-absorbing cotton, so that the air inlet noise is greatly reduced. When the muffling mechanism 8 needs to be maintained, the sound-absorbing cotton in the inside can be directly replaced by simply removing the cover plate 807, thereby further improving the maintenance efficiency and use convenience of the air compressor head.

[0034] As shown in Figure 3 , Figure 4 , the plurality of through slots 806 are linearly arranged at equal distances along the length line of the muffling box 801, the inside of the compression box 6 is in communication with the outside through the air inlet 901, the cavity 805 and the through slots 806, so that the external air can uniformly and smoothly flow into the cavity 805 of the muffling box. Meanwhile, since the inside of the compression box 6 is in communication with the outside through the air inlet 901, the cavity 805 and the through slots 806, the communication not only optimizes the air flow path, but also improves the air inlet efficiency of the air compressor head. More importantly, when the external air enters the compression box 6 through the path, the sound-absorbing cotton in the cavity 805 can effectively absorb and eliminate the noise, thereby significantly reducing the noise generated by the air compressor head during the air inlet process, and providing a more quiet and comfortable working environment for the operator.
