Specific embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein ad initio Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining Description of Drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

The collection cigarette for lampblack absorber 100 according to the utility model first aspect embodiment is described below with reference to Fig. 1-Fig. 9 Cover 10.Here, the exhaust fume collecting hood 10 for lampblack absorber 100 can be used for dust catcher, be suction when exhaust fume collecting hood 10 is used for dust catcher The dust gathering arrester of dirt device.

As shown in figure 1, according to the exhaust fume collecting hood 10 for lampblack absorber 100 of the utility model first aspect embodiment, including： Casing 11 and filter 12.

Specifically, limit in the cylindrical shape that casing 11 extends in (such as the above-below direction shown in Fig. 3) vertically, casing 11 Air-inlet cavity 1102 is determined, has been formed with air inlet and air outlet 1101 on casing 11, air inlet and air outlet 1101 are and air-inlet cavity 1102 connections, and the wind-guiding direction of air inlet and the wind-guiding direction of air outlet 1101 are in predetermined angle；That is, when air-flow from When air inlet inflow air-inlet cavity flows out from air outlet again, positioned at the air flow direction of air inlet position and positioned at the position of air outlet 1101 The no longer same straight line of air flow direction on.For example as shown in figure 1, the wind-guiding direction (air flow direction) of air inlet is from the bottom up Direction, the wind-guiding direction (air flow direction) of air outlet 1101 is direction from left to right, now the wind-guiding direction of air inlet and is gone out The angled setting in wind-guiding direction in air port 1101, so, the air-flow entered from air inlet will not directly along side from the bottom up Passed to from air outlet 1101, but need to change flow direction, so, the oil smoke that is mingled with air intake air-flow or dust can be caused more Rest on more in air-inlet cavity 1102, thus, it is possible to avoid oil smoke or dust from entering in exhaust passage from air outlet 1101, it is to avoid Oil smoke or dust adsorption influence its normal work to accumulation on blower fan or motor.

Filter 12 is located on casing 11 and covers air inlet, and filter 12 collectively defines air intake with casing 11 Chamber 1102.When lampblack absorber 100 works, outside oil smoke enters back into air-inlet cavity after first passing through the tentatively filtering of filter 12 In 1102, thus, it is possible to realize the effect of initial gross separation oil smoke, the oil smoke or dust entered in air-inlet cavity 1102 are reduced, so that Reduce greasy dirt or the dust accumulation in air-inlet cavity 1102.

According to the exhaust fume collecting hood 10 for lampblack absorber 100 of the utility model embodiment, oil smoke or dust can be avoided from going out Air port 1101 enters in exhaust passage, it is to avoid influence its normal work in oil smoke or dust adsorption to impeller or motor.

In some embodiments of the present utility model, reference picture 1, air inlet is formed in axial direction the one of casing 11 End (such as the lower end of the casing 11 shown in Fig. 1), air outlet 1101 is formed on the perisporium of casing 11.Thus, it is possible to make into Wind-guiding direction and the air-out of air inlet on the same line, are not realized in the wind-guiding direction in air port and the wind-guiding direction of air outlet 1101 The wind-guiding direction of mouth 1101 is in predetermined angle, so as to avoid oil smoke from entering in the drive device 30 in exhaust passage.

In certain embodiments, the angle between the wind-guiding direction of air inlet and the wind-guiding direction of air outlet 1101 can be In the range of 45 ° to 135 °.Further, the wind-guiding direction of air inlet can be perpendicular to the wind-guiding direction of air outlet 1101.By This, can further reduce oil smoke or dust enters motor 31 or wind wheel institute in an exhaust gas, meanwhile, also help oil The installation of the blast pipe 20 of cigarette machine 100 or the folding of dust catcher exhaust passage.

Advantageously, filter 12 can include linkage section 121 and extension 122, one end (such as Fig. 2 of linkage section 121 Shown in linkage section 121 lower end) with week of air inlet along being connected, and linkage section 121 at least a portion from periphery edge to Inner edge is inclined upwardly, that is to say, that at least a portion of linkage section 121 is in the central axis along casing 11 to air-inlet cavity 1102 The radially tapered taper of size on the direction (such as the direction from the bottom up shown in Fig. 2) of interior extension, extension 122 with The other end (such as the upper end of the linkage section 121 shown in Fig. 2) of linkage section 121 is connected, and linkage section 121 and extension 122 The inner side of casing 11 is respectively positioned on, linkage section 121 can be in along the central axis (such as the above-below direction shown in Fig. 2) of casing 11 The cylindrical shape of extension, and the upper end of linkage section 121 closed by cleaning device 15.Thus, it is possible to increase the area of air inlet, improve Air inlet reduces the loss of air inlet oil smoke so that the simpler conjunction of structure of filter 12 to the suction efficiency of oil smoke Reason.

In some embodiments of the present utility model, as Figure 4-Figure 6, air guide member can be provided with air-inlet cavity 1102 13, air guide member 13 can extend along the central axis (such as the above-below direction shown in Fig. 1) of casing 11, the periphery of air guide member 13 Be formed with multiple wind guide tanks 131 on face, multiple wind guide tanks 131 along air guide member 13 circumferentially-spaced arrangement, and multiple wind guide tanks 131 Central axis (such as the above-below direction shown in Fig. 1) along casing 11 extends.Multiple wind guide tanks 131 are used for air inlet position Air flow guiding to the position of air outlet 1101.Further, the bearing of trend perpendicular to wind guide tank 131 of wind guide tank 131 is (for example Above-below direction shown in Fig. 1) cross section it is V-shaped, and wind guide tank 131 relative two side wa ll circle arc transition, it is adjacent Arc transition between two adjacent two side walls of wind guide tank 131.Thus, it is possible to strengthen the wind effect of wind guide tank 131, carry The smoke pumping efficiency of lampblack absorber high 100.
