[0023] A clamping groove 4 is formed in the inner wall of the outer shell 1, and an acoustic cotton 5 is installed on the inner wall of the outer shell 1, wherein the acoustic cotton 5 comprises an acoustic cotton main body 51, a bonding plate 52, a clamping block 53 and a rubber pad 54, the bonding plate 52 is installed on the side wall of the acoustic cotton main body 51, the clamping block 53 is installed on the side wall of the bonding plate 52, the clamping block 53 can be inserted into the clamping groove 4, the rubber pad 54 is installed on the side wall of the bonding plate 52, and the rubber pad 54 can be bonded with the side wall of the outer shell 1.

[0024] A wind inlet 6 and a wind outlet 7 are formed in the side wall of the outer shell 1, and the air outlet end of the fan 2 can penetrate the side wall of the outer shell 1 through the wind outlet 7.

[0025] In this technical solution, the bonding plate 52 and the clamping block 53 are arranged on the side wall of the acoustic cotton main body 51, the acoustic cotton main body 51 can be easily installed on the inner wall of the outer shell 1 through the cooperation between the clamping block 53 and the clamping groove 4, and the clamping groove 4 formed in the inner wall of the outer shell 1 has a plurality of clamping grooves, so that the clamping block 53 can be inserted into the corresponding clamping groove 4 according to the size of the acoustic cotton main body 51.

[0026] The outer shell 1 in the present application adopts a split structure, so that the fan 2 and the acoustic cotton 5 can be conveniently installed, and the split outer shell 1 is assembled and closed by bolts.

[0027] In some technical solutions, an air inlet silencer 8 is inserted and installed in the air inlet 6, and the air inlet silencer 8 is connected with the air inlet end of the fan 2.

[0028] In this technical solution, the air inlet silencer 8 is a prior art, and the model is ZFX300, but it is not limited to this model, and it needs to be appropriately selected according to the air inlet amount of the fan 2. Through the arrangement of the air inlet silencer 8, the noise generated when the fan 2 inhales air can be greatly reduced.

[0029] In some technical solutions, the connecting seat 3 comprises a seat body 31, a through hole 32, a connecting bolt 33 and a buffer pad 34. The seat body 31 is installed on the inner wall of the shell 1. The side wall of the seat body 31 is provided with the through hole 32, which penetrates the side wall of the shell 1. The side wall of the seat body 31 is attached with the buffer pad 34. The connecting bolt 33 is inserted into the through hole 32. The side wall of the fan 2 is provided with a threaded hole. The bolt 33 can penetrate the side wall of the buffer pad 34 and be screwed into the threaded hole.

[0030] In this technical solution, the buffer pad 34 is arranged between the seat body 31 and the fan 2. When the fan 2 shakes after starting, it will not collide with the seat body 31, thereby generating noise. This further improves the control of the device on the noise of the fan 2.

[0031] In some technical solutions, the fan 2 is provided with a connecting cylinder 9. The side wall of the connecting cylinder 9 is sleeved with a rubber ring 10, which can be attached to the side wall of the air outlet 7. The end of the connecting cylinder 9 is provided with a connecting flange 11, which can be connected to the external pipeline.

[0032] In this technical solution, one end of the connecting cylinder 9 is connected to the air outlet end of the fan 2, and the other end is connected to the external pipeline through the connecting flange 11.

[0033] In some technical solutions, the side wall of one end of the connecting cylinder 9 located in the shell 1 is provided with a ventilation hole 12.

[0034] In this technical solution, the ventilation hole 12 allows the airflow in the connecting cylinder 9 to enter the shell 1 through the ventilation hole 12, thereby cooling the fan 2 and ensuring the stability of the fan 2. This avoids the damage of the internal motor due to high temperature caused by the operation of the fan 2 in a closed environment.

[0035] In some technical solutions, the lower wall of the shell 1 is provided with support feet 13 at the four corners. The upper wall of the support feet 13 is inserted with fixing bolts 14.

[0036] Working principle: open the shell 1, then install the sound-absorbing cotton body 51 on the inner wall of the shell 1 through the cooperation between the clamping block 53 on the outer side of the clamping plate 52 and the clamping groove 4, then install the fan 2 on the seat body 31 through the cooperation between the threaded hole and the connecting bolt 33, and make the connecting cylinder 9 pass out of the air outlet 7, then close the shell 1.

[0037] When the fan 2 is started, the external air enters into the air inlet end of the fan 2 through the air inlet muffler 8, in the process, the air inlet muffler 8 can control the noise generated by the air inlet, then the fan 2 accelerates the airflow and discharges through the connecting cylinder 9;

[0038] The shell 1 and the sound-absorbing cotton 5 on the inner wall of the shell 1 can control the noise generated by the fan 2.
