Simply describe the exhaust apparatus 300 according to the dust catcher of the embodiment of the present invention below with reference to Fig. 2, this exhaust apparatus 300 is located at the downstream of the motor cover of dust catcher and is communicated with motor cover with by the air outlet 260 in described motor cover.
Exhaust apparatus 300 according to the embodiment of the present invention comprises: hood 310 and filtration members 340.
As shown in Figure 2, hood 310 limits exhaust passage 320, exhaust passage 320 to be communicated with motor cover 240 by air outlet 260 and to be in communication with the outside by exhaust outlet 350, is becoming large from air outlet 260 gradually to the cross-sectional area of (direction of arrow namely in Fig. 2), exhaust passage 320 on the direction away from air outlet 260.
Filtration members 340 to be connected on hood 310 and to be located at exhaust outlet 350 place, is namely positioned at one end away from air outlet 260 of exhaust passage 320.Alternatively, filtration members 340 is HEPA filter screen.Thus, the gas of discharging from exhaust passage 320 flows out from HEPA filter screen, flow back in atmospheric environment.Preferably, on the flow direction of air, can to arrange multiple filtration members 340(figure side by side successively in the air exhaust passage 320 in adjacent row air port 350 not shown).
Thus, from the air that air outlet 260 is discharged, in exhaust passage 320 during flowing, cross-sectional area due to exhaust passage 320 becomes large gradually, flow velocity or the frequency of air draught can be changed, thus greatly reduce noise and the vibration of air draught generation itself, and then make 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 the cross-sectional area of exhaust passage 320 can be made to increase gradually.
In some preferred embodiments, the area of exhaust outlet 350 is at least the twice of the area of air outlet 260.Gas flow rate can be greatly reduced further thus, thus reduce noise and vibration, make muting function more obvious.
According to some embodiments of the present invention, exhaust apparatus 300 also comprises exhaust web plate 330, and as shown in Figure 2, exhaust web plate 330 is located on the air outlet 260 of the second motor cover 240, and exhaust web plate 330 has multiple 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, being shunted, and being changed its frequency.But behind exhaust passage 320, further reduction of speed is carried out to gas flow rate, and change its frequency further.
Alternatively, the cross sectional shape being vented mesh 331 is circle, polygon, ellipse or other shapes.Further, on the exhaust airstream direction of exhaust web plate 330, the cross section of exhaust mesh 331 increases gradually, schemes not shown.
Preferably, multiple exhaust mesh 331 is evenly distributed on exhaust web plate 330, as shown in Figure 2.In an alternate exemplary, multiple exhaust mesh 331 evenly distributed to arrange multiple row on exhaust web plate 330 more.In another alternate exemplary, multiple exhaust mesh 331 is evenly distributed with the annular shape be radially spaced on exhaust web plate 330.
According to some embodiments of the present invention, 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, described exhaust outer cover with limit the outer air duct be communicated with described exhaust passage by described exhaust collar extension between described hood.Thus, by arranging exhaust outer cover, by outer air duct, exhaust passage can be extended further, thus flow velocity is reduced to air draught, and change air-flow frequency further.
Below with reference to Fig. 1-Fig. 2, the dust catcher according to the embodiment of the present invention is described.
According to the dust catcher of the embodiment of the present invention, comprising: for collecting the dust collect plant 100 of dust, inlet duct 200 and exhaust apparatus 300, 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 the first sheathed successively from inside to outside motor cover 220, second motor cover 240, motor 210 is located at the first motor cover 220 being positioned at innermost layer, first motor cover 220 is communicated with dust collect plant 100 by air inlet 250, jointly limit air channel 270, second motor cover 240 between first motor cover 220 and the second motor cover 240 and there is air outlet 260.Alternatively, air inlet 250 place between dust collect plant 100 and the first motor cover 220 is provided with the filter screen 110 for filter dust.
Thus, motor 210 rotates and produce negative pressure in the first motor cover 220, and the air with dust is sucked in dust collect plant 100 mussily, and at air inlet 250 place, dust is filtered, and air enters in the first motor cover 220.Now, flowed in air channel 270 by the disorderly gas that motor 210 sucks, then discharge from the air outlet of the second motor cover 240, and by being discharged in air behind exhaust passage 320.
According to the dust catcher of the embodiment of the present invention, owing to enough extending the air channel length of air flowing, thus stabilize air current flow, and greatly reduce noise.In addition, according to dust catcher of the present invention, the simple cost of structure is low.
Referring again to Fig. 1-Fig. 2, the course of work of the dust catcher according to the embodiment of the present invention is specifically described below.
First, motor 210 rotates and produce negative pressure in the first motor cover 220, and the air with dust is sucked in dust collect plant 100 mussily, and at air inlet 250 place, dust is filtered, and air enters in the first motor cover 220.
As shown by the arrows in Figure 1, air-flow is sucked from air inlet 250 by motor 210, flows in the first motor cover 220, and the inwall along the first motor cover 220 flows, and from the first gas outlet 221 to air channel 270 in flow to air outlet 260.
Now, air draught is discharged from the exhaust web plate 330 be located at air outlet 260, exhaust web plate 330 has multiple exhaust mesh 331, thus reduces the flow velocity of exhaust gas from inlet duct 200, shunted, and change its frequency.Then, gas through exhaust web plate 330 flows in exhaust passage 320, cross-sectional area due to exhaust passage 320 becomes large gradually, change flow velocity or the frequency of air draught, thus greatly reduce noise and the vibration of air draught generation itself, and then make the muting function of dust catcher more obvious.
According to the concrete formation of integrating device in the dust catcher of the embodiment of the present invention and air inlet, exhaust apparatus other to form and operation is all known for those of ordinary skills, be not described in detail here.
In the description of this description, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present invention or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
Although illustrate and describe embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present invention and aim, scope of the present invention is by claim and equivalents thereof.
