Greatly, the mutual more smooth stabilization of action of lever 8 and push rod 4, and buffering is provided in the action that push rod 4 pushes lever 8, it protects
Driving structure and push-rod electric machine 3 are protected, the durability of whole flute check valve is improved.Push-rod electric machine 3 is towards left setting, push-rod electric machine 3
Forward direction operation, push rod 4 stretch out, drive lever 8 rotated counterclockwise as the center of circle using the shaft on lever support 9, drive wind shield 2 with
Shaft on rocker bar bearing 11 rotates counterclockwise for the center of circle, and wind shield 2 is opened, and flue is opened, and 3 inverted running of push-rod electric machine pushes away
Bar 4 is shunk, and lever 8 is driven to be rotated clockwise as the center of circle using the shaft on lever support 9, drives wind shield 2 with rocker bar bearing 11
On shaft rotated clockwise for the center of circle, wind shield 2 close, flue close.
It is top with 3 place side of push-rod electric machine, using 3 place side of push-rod electric machine as right side.
The push-rod electric machine 3 there is self-lock ability, when no power can be maintained at before in the state of, will not pushing away in oil smoke
The unstable rotation of dynamic lower generation, also can keep good leakproofness in the state that wind shield 2 is closed in this way.
The push-rod electric machine 3 is connect with control system, and control system includes PLC, and PLC input terminals include switch and smoke pumping
Machine, PLC output ends include push-rod electric machine 3, and the on/off of push-rod electric machine 3 can link with smoke exhaust ventilator on/off, open and take out
The positive operation of push-rod electric machine 3, opens wind shield 2 when switch for cooker hood, opens flue, push-rod electric machine when closing switch for fume exhauster
3 inverted runnings close wind shield 2, close flue.It on this basis can also be by the smoke exhaust ventilator and push rod electricity in whole residential house
Machine 3 is attached with control system, 3 inverted running of push-rod electric machine that will be not turned in the family of smoke exhaust ventilator, closes flue,
The generation of taste, taint of odour phenomenon is not only avoided down, and the exhausting effect of flue can be promoted.
1 both ends open of the shell can be connect by converting interface with common flue and family's flue, is completely embedded, is not present
Interface leak runs the risk of cigarette, is not construed as limiting to 1 shape of shell, can carry out interface conversion by converting interface.
The push-rod electric machine 3 is covered with electric motor protecting shell, can be protected to push-rod electric machine 3, prevent damage of colliding with
Situation, and prevent the oil smoke in flue from entering the unexpected region of flue, oil smoke is enclosed in flue, is avoided outside pollution flue
Environment is equipped with sealing hairbrush at 1 upper opening of shell, in each one sealing hairbrush of setting in 8 both sides of lever, the sealing hairbrush on both sides
It is interference fitted, lever 8 can pass through when acting in sealing hairbrush, will not be had an impact to the action of lever 8, by shell 1
Internal 3 part of push-rod electric machine on shell 1 carries out isolation processing, prevents oil smoke erosion pollution, improves push-rod electric machine 3 and driving
The durability of structure.
It should be understood that the above is only the preferred embodiment of the utility model only, it is not sufficient to limit this reality
With novel technical solution, for those of ordinary skills, within the spirit and principles of the present invention, Ke Yigen
Increased and decreased according to above description, replaced, converted or is improved, and all these increases and decreases, replacement, transformation or improved technical side
Case should all belong to the protection domain of the appended claims for the utility model.
