Detailed Description
In order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
As shown in fig. 1-4, the utility model provides a through-wall muffler, the through-wall muffler includes:
a sleeve 1 provided with an air inlet and an air outlet;
the first silencing cotton 2 is fixed in the sleeve 1; and
and the second silencing cotton 3 is fixed in the sleeve 1, and the first silencing cotton 2 and the second silencing cotton 3 are connected together in a staggered manner, so that an s-shaped air channel is formed in the sleeve 1.
It is specific, cotton 2 of first amortization and the cotton 3 of second amortization are in the same place through the glue adhesion, and the cotton 3 of second amortization is connected between two adjacent first amortization cotton 2, and two adjacent second amortization cotton 3 take the dislocation set again, make the wind channel in the wall muffler be the s type, the wind channel of s type can effectual direction and the speed that changes the wind, in addition the cotton effect of amortization, the noise reduction that can be great, and the whole shape of this embodiment is the tubulose, can adjust the volume size according to new fan blast pipe, the new fan of the various models of adaptation that can be fine.
In some embodiments, the cannula 1 is pvc material.
Specifically, in this embodiment, the sleeve 1 is made of transparent PVC, and the wall thickness is preferably 1mm to 5mm, so that the first noise reduction cotton 2 and the second noise reduction cotton 3 can be better installed and protected.
In some embodiments, the first noise reduction cotton 2 is cylindrical, and a cylindrical first through hole is formed in the center of the first noise reduction cotton 2.
In some embodiments, the first sound-damping cotton 2 is PU cotton.
Specifically, the first silencing cotton 2 and the second silencing cotton 3 are both made of PU cotton, and micro air-permeable small holes are densely distributed in the first silencing cotton 2 and the second silencing cotton 3 and used for reducing noise and filtering particles.
