The specific embodiment

Below will and be described further in conjunction with the accompanying drawings with the specific embodiment of the present utility model.

As shown in Figure 1 to Figure 3, induced-draft fan of the present utility model comprises that a profile is the noumenal seat 10 of long rectangle and the swing-arm type oil smoke cover 20 of a prolate tubulose, wherein, this swing-arm type oil smoke cover 20 is in the mode of fan-shaped rotary moveable up and down, this swing-arm type oil smoke cover 20 utilizes tenon axle or latch 24 to be connected outward appearance and is on the pin-and-hole 15 of two side 12 of noumenal seat 10 of long rectangle, so can be dismantled easily and clean easily.

The inside of this noumenal seat 10, form hollow cavity 14, be provided with groups of motors 50 and mist extractor impeller 40, its front side wall 16 belows form air inlet duct (not marking in the accompanying drawing) especially, upper side wall 11 then offers a gas outlet 13, when supply power, groups of motors 50 drives 40 rotations of mist extractor impeller, by the powerful hollow cavity 14 that attracts air-flow to enter noumenal seat 10 in air inlet duct place, gas outlet 13 by upper side wall 11 excludes again, make the hollow cavity 14 of noumenal seat 10 form the powerful air-flow that one flows from lower to upper, in addition, in end face the place ahead of the upper side wall 11 of noumenal seat 10, and be provided with a stepless on-slip device 30, be suspended in drawing line 31 on the end face of swing-arm type oil smoke cover 20, because swing-arm type oil smoke cover 20 selects for use slim and graceful material such as aluminum or aluminum alloy to make, so swing-arm type oil smoke cover 20 can be fixed in mobilizable scope by drawing line 31, i.e. any position of aloft being rotated, but and return to primitive age position.

Swing-arm type oil smoke cover 20 is the prolate tubulose, the inner space forms hollow cavity 23, be used for constituting the passage that absorbs oil smoke and guiding oil smoke, so, the cover 21 of swing-arm type oil smoke cover 20, offer smoking port 22, and the lower end of swing-arm type oil smoke cover 20 constitutes opening, form smoke guide port 25, its position is that fit is embedded in the special air inlet duct that forms in front side wall 16 belows of noumenal seat 10, communicate with the hollow cavity 14 of noumenal seat 10, so when the groups of motors 50 of noumenal seat 10 inside drives 40 rotations of mist extractor impeller, promptly, form strong attraction, produce the effect (as shown in Figure 3) that significantly absorbs oil smoke and get rid of oil smoke at smoking port 22 places of the cover 21 of swing-arm type oil smoke cover 20.

The left and right sides sidewall of this swing-arm type oil smoke cover 20 is near smoke guide port 25 places, be provided with tenon axle or latch 24, be used for being snapped in the pin-and-hole 15 on noumenal seat 10 left and right sides sidewalls 12, make that bed rearrangement swing-arm type oil smoke cover 20 is the axle center fulcrum with pin-and-hole 15, the generation fan shape rotates, and makes the position of the smoke guide port 25 of swing-arm type oil smoke cover 20, still keeps communicating (as shown in Figures 2 and 3) with the hollow cavity 14 of noumenal seat 10, simultaneously, can utilize the drawing line 31 of aforesaid stepless trigger 30 to fix the position.
