However, the larger the wide-width print medium, the more suction devices are required to suction and fix the print medium, but the increased number of suction devices means that the larger the noise is, the staff work in such a noisy environment, which is unfavorable for physical and psychological health.

In view of this, the present application provides a bellows 100 in which sound-absorbing layers 10 are provided on the inner wall of a housing 10, and a muffler pipe 22 is provided on the air outlet end 21b of a main body 21 of a fan 20, and sound waves formed in the housing 10 are reflected between the sound-absorbing layers 10 to be gradually converted into heat energy, which is primary noise reduction; the air flow enters the muffler pipe 22 through the main body 21, and the noise formed is converted into heat energy by the muffler pipe 22, which is a secondary noise reduction. Thus, the bellows 100 provided by the present application can greatly reduce the working noise.

Specifically, referring to fig. 1 and 2, an embodiment of the present application provides a bellows 100 for reducing noise of an air suction device, including a housing 10 and a fan 20.

The case 10 is used for providing a receiving space 10a of the fan 20, and noise is reduced or eliminated in the case 10. The blower 20 is a power source for adsorbing the printing medium.

It will be appreciated that the bottom and top faces of the housing 10 are opposed, i.e. the external air flow enters from the bottom of the housing 10 and exits from the top. During inflow and outflow, noise generated inside the cabinet 10 is absorbed by the sound absorbing layer 10, thereby achieving a noise reduction effect.

Here, the sound absorbing layer 10 may have a high gap of sound absorbing cotton, noise is continuously reflected and collided in the gap of the sound absorbing cotton, and finally sound wave energy is converted into heat energy. Of course, the sound-absorbing layer 10 may also be formed into a layered structure for other sound-absorbing materials having void spaces, such as polymers, fibers, and the like.

The bellows 100 provided by the utility model can be used for noise reduction of air suction equipment. The case 10 has a receiving space 10a, and an air suction port 10b and an air outlet 10b are opened on a bottom end surface and a top end surface of the case 10, respectively, so that the receiving space 10a of the case 10 communicates with the outside, and air is sucked into the case 10 from the outside through the air suction port 10b by a main plate portion of the blower 20, and is discharged through the air outlet 10b by the muffler pipe 22. Because the sound-absorbing layers 10 are arranged on the inner wall of the box body 10, sound waves formed in the box body 10 are reflected among the sound-absorbing layers 10 and gradually converted into heat energy, and the heat energy is first-stage noise reduction; the air flow enters the muffler pipe 22 through the main body 21, and the noise formed is converted into heat energy by the muffler pipe 22, which is a secondary noise reduction. Thus, the case 10 of the present application can reduce the operation noise to a greater extent in the operation process.

In one implementation, the blower 20 is a variable frequency blower. The main body part 21 of the variable frequency fan has smaller noise in the starting process, and can reduce the noise from the source.
