The model of the single-chip microcontroller are as follows: STC89C51.
The working principle of the invention is: conehead bar of the invention is solid, and material is iron;Fixed bowl cover is with small prominent
It rises, plays the role of positioning;Original state, hearth are hidden under smoke exhaust ventilator, and conehead bar, intermediate bar are contracted to upper end at this time
Extreme position, and the conical nose of conehead bar passes through four holes on hearth, the spring in slip lid is elongation state at this time, and two is sliding
Block is peaked in the hole on hearth, and conehead bar is made to be limited in slider bottom, and conehead bar holds hearth at this time, and steel cable is by pulling force in tight
Taut state;By lower switch, motor reversal, driving gear drives driven gear rotation, and driven gear drives support shaft rotation, branch
It supports shaft and drives rope winding disc rotation, slack cables, conehead bar are moved down by self gravity and the gravity of hearth at this time;Turn
After a dynamic fixing turn, end in contact kitchen face under hearth, motor stalls, conehead bar, intermediate bar are respectively positioned on lower end limit position at this time
It sets;Hearth lower end is equipped with pressure sensor, and after hearth touches kitchen face, the electromagnet of hearth lower end is powered, the cunning in slip lid
Block is moved by magnetic force to electromagnet direction, spring contraction;Motor rotates forward, and driving gear drives driven gear rotation, driven
Gear drives support shaft rotation, and support shaft drives rope winding disc rotation, and steel cable tension, pulls conehead bar to move up at this time,
After conehead bar collapses into intermediate bar completely, the conehead part of conehead bar drives intermediate bar to continue to move up, when intermediate bar is complete
After collapsing into fixed link entirely, motor stalls, steel cable is tight state at this time, and conehead bar, intermediate bar are located at upper end limit position
It sets, at this time the electromagnet power loss in the slip lid of hearth lower end, spring elongation, sliding block is pushed into hole;Switch is pressed again, and motor is anti-
Turn, slack cables, conehead bar is moved down by self gravity, and conehead bar enters in four holes of hearth, the cone head part of conehead bar
It is divided to and opens two sliding blocks, at this time spring contraction, when conehead bar reaches lower end extreme position, the conehead part of conehead bar is more than sliding block
Low side, spring extends at this time, and sliding block is tightly pressed against the bar portion of conehead bar.
