When dust catcher works, the air with dust is sucked from ground brush assemblies 500, when by connecting pipe component 100,
As shown in Figure 2 and Figure 4（Arrow shows airflow direction in Fig. 4）, the flowing in connecting tube 1 of the air with dust, from first
Through hole 11 is outwardly into the silencing cotton 3 set in annular gap 20, is propagated in silencing cotton 3, then entered by first through hole 11
Enter in connecting tube 1, then entered in dust exhaust apparatus 200 by flexible pipe 300.
Thus, the connecting pipe component for dust catcher according to embodiments of the present invention, is provided with first logical in connecting tube 1
Hole 11 and silencing cotton 3, thus serve the effect of noise reduction during air current flow, change air current flow wave amplitude or its
His parameter, in the process, changes the wave amplitude of the air-flow for flowing through connecting tube（As shown in Figure 4）, thus slow down the stream of air-flow
Speed, and then the friction between air-flow and the inwall of connecting tube 1 is reduced, greatly reduce the noise of dust catcher product, improve property
Energy.
According to one embodiment of present invention, as shown in Figure 1-Figure 3, multiple first through hole 11 in connecting tube 1 vertically
Be uniformly distributed circumferentially, the pore diameter range of first through hole 11 is 1.5-3mm.Thus it is simple to manufacture and noise reduction is more preferable.
Alternatively, as depicted in figs. 1 and 2, silencing cotton 3 is formed as annular tube shaped and is set on the periphery wall of connecting tube 1,
The periphery wall of silencing cotton 3 and the inwall of outer tube 2 stop to.So that air-flow enters the annular gap between connecting tube 1 and outer tube 2
Propagated in silencing cotton 3 when interior, so as to ensure that erasure effect.
In certain embodiments, silencing cotton 3 includes at least two, and at least two silencing cottons 3 are along the axial direction side of connecting tube 1
To setting spaced apart.Alternatively, baffle plate 4 is provided between per two neighboring silencing cotton 3, as shown in Figure 1-Figure 3, baffle plate 4 is from even
Radially stretched out on the periphery wall of adapter 1, baffle plate 4 is provided with along its circumferentially-spaced multiple second through hole 41 for opening distribution.
Preferably, the pore diameter range of each the second through hole 41 is 1.5-3mm.Alternatively, the second through hole 41 be formed as it is circular, oval or
Polygon.Thus, flowed after air-flow enters in a silencing cotton 3 from first through hole 11, by the second through hole reality on baffle plate 4
Aperture noise reduction is showed, has then entered back into another silencing cotton 3, so as to reduce further noise.
As depicted in figs. 1 and 2, in some preferred exemplaries of the invention, in the connection of the two ends of silencing cotton 3 and outer tube 2
Place has sealing ring 5 respectively.
The dust catcher of embodiment according to a second aspect of the present invention is described with reference to Fig. 5 first below.As shown in figure 5, dust catcher
Including：Dust exhaust apparatus 200, flexible pipe 300, connecting pipe component 100, expansion link 400 and ground brush assemblies 500, wherein dust exhaust apparatus 200
With air inlet 210, one end of flexible pipe 300 is connected with air inlet 210, and connecting pipe component 100 connects with the other end of flexible pipe 300
Logical, ground brush assemblies 500 are connected with connecting pipe component 100 by expansion link 400 and deliver to dust exhaust apparatus 200 with by the dust of suction
It is interior.
When dust catcher works, the motor in dust exhaust apparatus 200（It is not shown）Rotate, in the motor of dust exhaust apparatus 200
Cover（It is not shown）Interior formation subnormal ambient so that the air with dust is sucked from ground brush assemblies 500, by connecting tube group
During part 100, as shown in Figure 2 and Figure 4（Arrow shows airflow direction in Fig. 4）, the stream in connecting tube 1 of the air with dust
It is dynamic, it is outwardly into the silencing cotton 3 set in annular gap 20 from first through hole 11, by between silencing cotton 3 and silencing cotton 3
Second through hole of baffle plate 4 is propagated, then is entered in connecting tube 1 by first through hole 11, then enters dust exhaust apparatus by flexible pipe 300
In 200.Thus, air-flow wave amplitude is increased, air-flow velocity is slow down, the friction of air-flow and the inwall of connecting tube 1, Jin Ershi is reduced
The purpose for reducing noise is showed.
Dust catcher according to embodiments of the present invention other constitute for example dust exhaust apparatuses 200 and ground the grade of brush assemblies 500 and
Operation is all for those of ordinary skills known, is not detailed herein.
