Embodiment 1.
Studying discovery through inventor, the existing not smooth reason of most lampblack absorber smoke evacuations has following:
Reason one: newly-built building is when handing over room, and kitchen chimney flue mouth only all can install common Smoke prevention
Inverse valve, such resident family, when moving in finishing, will use the mode of furred ceiling to cover oil smoke outlet
The namely installation site of Smoke prevention check (non-return) valve, and furred ceiling has removable aluminum blockage furred ceiling, also
There are non-disconnectable Integral ceiling and plaster tablet suspended ceiling, owing to the check (non-return) valve on range hood is with only
The knot that the Smoke prevention check (non-return) valve that vertical pin is sold mostly uses range hood wind-force to open, valve block deadweight is closed
Structure, fraction adds shock mount to help valve closing on valve block.In order to ensure range hood wind-force
Can blow check (non-return) valve, valve block weight or spring force open can not be excessive, so valve closing power is less,
Valve block is easily by grease adhesion.After valve block adhesion, check (non-return) valve open and close are the most not in place, open not in place
Consequence is that air draft is not smooth, and it is to occur substantial amounts of oil smoke to pour in down a chimney that consequence not in place is closed in air quantity decay,
If keeped in repair, removable maintenance cost and operation are the easiest, and if can not
The Integral ceiling torn open or plaster tablet suspended ceiling are not substantially just changed, because such furred ceiling is basic
On Smoke prevention check (non-return) valve is completely enclosed within above furred ceiling, there is no operable space, if to keep in repair,
It is necessary for furred ceiling to remove, and because such maintenance cost is the highest, causes resident family to be unwilling
Spending big price to keep in repair, prefer to stand the misery that oil smoke pours in down a chimney, this is that existing check (non-return) valve is installed
The not maintainability that the defect of fixed position causes；Even if resident family is ready to remove renovated hanging
The check (non-return) valve more renewed is removed on top, but new check (non-return) valve still there will be after using a period of time equally
Problem, such resident family goes to remove the classes such as renovated Integral ceiling or plaster tablet suspended ceiling again
As unreducible furred ceiling keep in repair check (non-return) valve, can significantly cut down resident family maintenance consciousness, because of
The most complicated for maintenance procedures and cost is the highest, the most traditional anti-fire check valve is all dependent on
Mechanical metal thermal sensitive piece monitors the fire condition in flue, if it occur that fire, mechanical
Sensing response fire spread can be made slowly to come in and also after fire is decorporated check (non-return) valve maintenance procedures big.
Reason two: the mode that the valve block that existing common check (non-return) valve is mostly used opens and closes
All blow open by lampblack absorber wind-force, the intelligence that functional any reliable motor-driven strong is opened
Energy electric check (non-return) valve, the problem that all can occur not growing service life, blow by lampblack absorber wind-force
The check (non-return) valve opened be essentially all valve block be stained with oil stain otherwise be not closed completely cause oil smoke to pour in down a chimney, want
Stick to blow and do not convinced cause oneself oil smoke row by patient analysis and do not go out.
Reason three: although having driving motor to make than the new intelligent electric check valve of more recent at present
For transmission, but control to drive the transmission of motor to uniquely rely on simple circuit or stroke type switch comes
The main story driving motor controlled and reversion, lack the detection function of self, strong and weak electricity isolation merit
Can, anti-interference function and fault alarm function, these defects all safety to user is brought hidden
Suffer from.
Install and safeguard that inconvenient reason is just because check (non-return) valve and can be only installed at flue entrance
Place and resident family's kitchen fitting structure cause.
Discharge fume the most smooth reason: accumulation grease on check (non-return) valve makes valve block weight increase, valve block
On add check (non-return) valve after shock mount and open resistance and increase, fume-exhausting confidential consumption part air quantity overcomes
These resistances；The check (non-return) valve being particularly wall-mounted on common flue mouth is all bottom-open type, and valve block is not
Can open to put in place and reduce ventilation section, these will cause exhaust air rate to decay, and discharges fume the most smooth.
Or occur that valve block clings the air draft of lampblack absorber and blows not open so that the oil smoke of own home can not arranged
Go.
