Description
Technical field
The present invention relates to a kind of range hood, there is the oil suction of the elevating mechanism more particularly, to a kind of elevating mechanism and application
Cigarette machine.
Background technology
Existing elevating mechanism has a lot, such as common leading screw and nut mechanism, and it mainly includes screw mandrel and two, nut
The component of mutual cooperation, generally, load are arranged on nut, drive nut and load can be along screw mandrel by the rotation of screw mandrel
Carry out corresponding sports.It is well known that the size of the lead angle of screw mandrel directly affects the performance of leading screw and nut mechanism, if spiral
Lift angle is larger, although require low to motor speed, but mechanism self-lock ability is poor, easily produces load and slides phenomenon；If spiral
Lift angle is smaller, although mechanism self-lock ability is stronger, loads unfavorable landing, but requires higher to motor speed, and motor speed is improved,
It is easily caused noise increase.Therefore, in order to avoid motor produces larger noise, the lead angle of screw mandrel will not design too small,
Thus the problem of bringing be, when leading screw and nut mechanism as elevating mechanism is supported on decline process in use, hanging on nut
It is middle that the wild effect of " weightlessness " can be produced because of deadweight, so that elevating mechanism produces shake, abnormal sound in motion process.
In addition, the smoke absorption effect in order to improve range hood, people have invented the various oil suctions with movable smoke deflector
Cigarette machine, typically by elevating mechanism driving smoke deflector carry out elevating movement, and then adjust range hood air inlet angle and
Intake.It is common to there is smoke deflector shifting although smoke absorption effect can be greatly improved by the lifting activity of smoke deflector
Not stable enough phenomenon is moved, Consumer's Experience is poor.
