Below with reference to Fig. 2, simply describe according to the exhaust apparatus 300 of the dust catcher of the utility model embodiment, this exhaust apparatus 300 be located at dust catcher motor cover downstream and be communicated with motor cover with the air outlet 260 by described motor cover.
According to the exhaust apparatus 300 of the utility model embodiment, comprise: hood 310 and filter member 340.
As shown in Figure 2, hood 310 limits exhaust passage 320, exhaust passage 320 is communicated with motor cover 240 and is in communication with the outside by exhaust outlet 350 by air outlet 260, from air outlet 260 direction away from air outlet 260 cross-sectional area of (being the direction of arrow in Fig. 2), exhaust passage 320 become gradually large.
Thus, the air of discharging from air outlet 260, in exhaust passage, 320 is interior when mobile, because the cross-sectional area of exhaust passage 320 becomes large gradually, can change flow velocity or the frequency of air draught, thereby reduced widely noise and vibration that air draught itself produces, and then made the muting function of dust catcher more obvious.Wherein, those skilled in the art are appreciated that the profile of hood 310 can design according to the profile of specific product, as long as can make the cross-sectional area of exhaust passage 320 increase gradually.
In some preferred embodiments, the area of exhaust outlet 350 is at least the twice of the area of air outlet 260.Can further greatly reduce gas flow rate thus, thereby reduce noise and vibration, make muting function more obvious.
According to embodiment more of the present utility model, exhaust apparatus 300 also comprises exhaust web plate 330, and as shown in Figure 4, exhaust web plate 330 is located on the air outlet 260 of the second motor cover 240, and exhaust web plate 330 has a plurality of exhaust mesh 331.Thus, by being located at the exhaust web plate 330 on air outlet 260, as the ground floor exhaust structure of exhaust apparatus, for reducing the flow velocity of exhaust gas from inlet duct 200, shunted, and changed its frequency.Yet behind exhaust passage 320, further gas flow rate is carried out to reduction of speed, and further change its frequency.
Alternatively, the cross sectional shape of exhaust mesh 331 is circle, polygon, ellipse or other shapes.Further, in the exhaust airstream direction of exhaust web plate 330, the cross section of exhaust mesh 331 increases gradually, schemes not shown.
Preferably, a plurality of exhaust mesh 331 are evenly distributed on exhaust web plate 330, as shown in Figure 4.In an optional example, a plurality of exhaust mesh 331 evenly distributed to arrange multiple row on exhaust web plate 330 more.In another optional example, a plurality of exhaust mesh 331 are evenly distributed with the annular shape being radially spaced on exhaust web plate 330.
According to embodiment more of the present utility model, exhaust apparatus 300 can also comprise exhaust outer cover, scheme not shown, described exhaust external cover is located at the outside of described hood and has exhaust collar extension, between described exhaust outer cover and described hood, limits the outer air duct being communicated with described exhaust passage by described exhaust collar extension.Thus, by exhaust outer cover is set, can exhaust passage further be extended by outer air duct, thereby air draught is reduced to flow velocity, and further change air-flow frequency.
Below with reference to Fig. 1-Fig. 2, describe according to the dust catcher of the utility model embodiment.
Dust catcher according to the utility model embodiment, comprising: for collecting dust collect plant 100, inlet duct 200 and the exhaust apparatus 300 of dust, wherein exhaust apparatus 300 is the exhaust apparatus of the dust catcher in above-described embodiment.Alternatively, dust collect plant 100 comprises dust bag or dust pocket.
As shown in Figure 1, inlet duct 200 comprises motor 210 and sheathed the first motor cover 220, the second motor cover 240 successively from inside to outside, motor 210 is located at the first motor cover 220 that is positioned at innermost layer, the first motor cover 220 is communicated with dust collect plant 100 by air inlet 250, between the first motor cover 220 and the second motor cover 240, jointly limit air channel 270, the second motor cover 240 and there is air outlet 260.Alternatively, air inlet 250 places between dust collect plant 100 and the first motor cover 220 are provided with for filtering the filter screen 110 of dust.
Thus, motor 210 rotates in the interior generation negative pressure of the first motor cover 220, with the air of dust, is sucked mussily in dust collect plant 100, at air inlet 250 place's dusts, is filtered, and air enters in the first motor cover 220.Now, the disorderly gas being sucked by motor 210 270 flows in air channel, then from the air outlet of the second motor cover 240, discharge, and by being discharged in atmosphere behind exhaust passage 320.
According to the dust catcher of the utility model embodiment, owing to enough having extended the air channel length of Air Flow, thereby stablized air current flow, and greatly reduced noise.In addition, according to dust catcher of the present utility model, cost simple in structure is low.
Below referring again to Fig. 1-Fig. 2 to being specifically described according to the course of work of the dust catcher of the utility model embodiment.
First, motor 210 rotates in the interior generation negative pressure of the first motor cover 220, with the air of dust, is sucked mussily in dust collect plant 100, at air inlet 250 place's dusts, is filtered, and air enters in the first motor cover 220.
As shown by the arrows in Figure 1, air-flow is sucked by motor 210 from air inlet 250, flows in the first motor cover 220, mobile along the inwall of the first motor cover 220, and flow to air outlet 260 in the first 221Dao air channel, gas outlet 270.
Now, air draught is discharged from the exhaust web plate 330 being located at air outlet 260, has a plurality of exhaust mesh 331, thereby reduced the flow velocity of exhaust gas from inlet duct 200 on exhaust web plate 330, is shunted, and changes its frequency.Then, the gas of process exhaust web plate 330 is 320 interior flowing in exhaust passage, because the cross-sectional area of exhaust passage 320 becomes large gradually, flow velocity or the frequency of air draught have been changed, thereby reduced widely noise and vibration that air draught itself produces, and then made the muting function of dust catcher more obvious.
According to other formations of the concrete formation of integrating device in the dust catcher of the utility model embodiment and air inlet, exhaust apparatus and operation, be all known for those of ordinary skills, be not described in detail here.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
