The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The embodiment of the ventilating system of the utility model, as shown in Figures 1 to 4, ventilating system, including vent assemblies
And blower, the other component in blower and ventilating system are in the prior art that details are not described herein.Vent assemblies packet
Two ventilation shafts being mutually butted are included, in this embodiment, the two ventilation shafts are that the first ventilation shaft 1 and second is logical respectively
Air piping 2, one butt end is equipped with flaring structure in two ventilation shafts, another butt end is equipped with and flaring is tied
Structure seals the fit structure of cooperation, is equipped with the protrusion outwardly protruded on the periphery at two ventilation shaft docking locations, divulges information
Conduit assembly further includes retaining mechanism, and retaining mechanism includes two fixture blocks 4 for being articulated and connected and being clasped with corresponding protrusion,
The two fixture blocks 4 are the first fixture block 11 and the second fixture block 21 respectively, are realized and are articulated and connected by articulated shaft 41 between two fixture blocks,
It is coated between two fixture blocks for providing the clamping screw 5 of clamping force to two fixture blocks.In the present embodiment, retaining mechanism exists
At docking location it is circumferentially-spaced be equipped with it is multiple, guarantee to provide sufficiently large coupling mechanism force, while each locking mechanism ruler in this way
It is very little smaller, it is easily installed.
In the present embodiment, flaring structure is the bellmouth being arranged on the end face of the butt end of corresponding ventilation shaft,
Fit structure is the conical nose being adapted to bellmouth, sealing ring 111 is equipped between bellmouth and conical nose, bellmouth has
Preferable centering effect, and it is easy to process, while it being also convenient for setting sealing ring 111, in the present embodiment, to guarantee sealing effect
Fruit, sealing ring 111 are equipped at intervals with multiple.
In the present embodiment, between two fixture blocks for being oat tail groove structure with the grasping part of male cooperation, two
Male cooperation forms the swallow-tail form protrusion being adapted to dovetail groove, can guarantee that closed position has by the cooperation of oat tail groove structure
The anticreep coupling mechanism force of fastening, and using this structure avoid that mounting hole is arranged on ventilation shaft, avoid the knot of ventilation shaft
Structure intensity is affected.
In the present embodiment, it is equipped in the inner cavity of the ventilation shaft of airflow direction upstream and overhangs into another ventilation shaft
And with the spaced guide duct 3 of its inner wall, i.e. be provided with guide duct 3 in the first ventilation shaft 1, guide duct 3 with it is corresponding logical
Interval between the inner wall of air piping forms silencing cavity, and the bloop 31 of connection its inner cavity and silencing cavity is distributed on guide duct 3.
Air-flow in the circulation process, is entered in the ventilation shaft in downstream, simultaneously, a part of air-flow passes through noise reduction by guide duct 3
Hole 31 enters back into ventilation shaft after being introduced into silencing cavity, and such two parts air-flow can interact, to further eliminate
Noise plays erasure effect.
In the present embodiment, bloop 31 is set in a row in the circumferential direction of guide duct 3, and bloop 31 is distributed in guide duct
