Abstract
The utility model relates to a ventilating device on the tail end of an air conditioner, and more specifically is a silencing telescopic flexible pipe. The utility model comprises a telescopic pipe core, a filling layer, and a silencing telescopic flexible pipe of an inner multilayer. The utility model is characterized in that one layer of outer multilayer (1) is coated on the outer surface of the pipe core. The outer multilayer (1) adopts glass fibre cloth composite aluminum materials. The inner multilayer (2) adopts centrifugal glass cotton materials. The filling layer (3) adopts non-woven cloth materials. The pipe core (4) is composed of crossing sound hole metal plastic aluminum foil flexible pipe materials. The utility model can ensure that ventilation is smooth, and can lead audio to be sufficiently absorbed. The ventilating device has better rebound resilience, and simultaneously plays the role of heat insulation.
Description
The utility model relates to a kind of ventilation unit of air conditioning terminal, specifically the noise reduction bellows.
As everyone knows, existing noise reduction bellows is made of flexible tube core, packing course, interior multiple layer, and this noise reduction bellows is owing to design is unreasonable, and windage increases by 2% than original in actual applications, and quiet sound effective value is poor.
The purpose of this utility model is to provide a kind of novel noise reduction bellows, can be applicable to the ventilation unit of air conditioning terminal, plays quiet sound effective value.
For achieving the above object, according to the characteristics of audio frequency, general more at the ventilation unit medium and low frequency noise of air conditioning terminal, the frequency of low frequency is long, so adopt the thickness of rotary glass cotton material to add solution.The appearance of tube core (4) is surrounded by one deck outer covering layer (1), outer covering layer (1) adopts the multiple aluminum of glass cloth, interior multiple layer (2) adopts the rotary glass cotton material, packing course (3) adopts nonwoven cloth material, tube core (4) adopts intersection sound hole metal plastic cement aluminium foil hose material to form, and this complex technique is conspicuous to this professional people.
The utility model compared with prior art allows audio frequency be absorbed fully, has resilience preferably, and it is unimpeded to guarantee to ventilate, and has also played heat-blocking action simultaneously.
Be elaborated below in conjunction with accompanying drawing:
Fig. 1 is a structure cutaway view of the present utility model.
Referring to Fig. 1: the 1-outer covering layer, adopt the multiple aluminum of glass fibers cloth to make, play the ventilating heat-proof effect.Multiple layer adopts the rotary glass cotton material in the 2-, and in the transmission of large-size air conditioning equipment wind, because wind-force is big, low-frequency noise is also many, and this just needs to reduce noise.The 3-packing course adopts nonwoven cloth material, plays the transmission effect of keeping out the wind.The 4-tube core adopts intersection sound hole metal plastic cement aluminium foil hose material, and numerous aperture is arranged on the wall of tube core, laterally walks in the footpath along tube wall, guarantees that wind-force passes through, and noise spreads out of by aperture, is restrained by the rotary glass cotton material.The helical flute of 5-tube core itself.In order to make accompanying drawing 1 see clearly Chu, thickness had carried out amplifying signal when outer covering layer (1) was drawn.
Claims (1)
1. one kind comprises flexible tube core, packing course, the interior noise reduction bellows of layer again, the appearance that it is characterized in that tube core is surrounded by one deck outer covering layer (1), outer covering layer (1) adopts the multiple aluminum of glass cloth, interior multiple layer (2) adopts the rotary glass cotton material, packing course (3) adopts nonwoven cloth material, and tube core (4) adopts intersection sound hole metal plastic cement aluminium foil hose material to constitute.
