Specific embodiment
Below in conjunction with the attached drawing in utility model embodiment, the technical solution in utility model embodiment is carried out clear
Chu is fully described by, it is clear that described embodiment is only a part of the embodiment of utility model, rather than whole realities
Apply example.Based on the embodiment in utility model, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, belongs to the range of utility model protection.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only in utility model embodiment
For explaining in relative positional relationship, the situation of movement etc. under a certain particular pose (as shown in the picture) between each component, if
When the particular pose changes, then directionality instruction also correspondingly changes correspondingly.
With reference to shown in Fig. 1, Fig. 5, exhaust apparatus 10 include braced frame 11, braced frame 11 can be it is semi-enclosed for example
Either full open model with open box.Braced frame 11 includes an extruding fixed board (bottom plate 12 in first embodiment
And the inclined side plate 23 in second embodiment).Exhaust apparatus 10 further include the extruding movable plate 13 in the braced frame 11 with
