Description

A kind of range hood elevating mechanism
Technical field
The utility model is related to range hood fields, and in particular to range hood elevating mechanism.
Background technology
Range hood on the market is mostly integral structure at present, and the area occupied is all bigger, from modern house household electrical appliances Future developing trend sees, intelligence, hommization, multifunction are the developing direction of kitchen appliance.Automatic-lifting type kitchen ventilator is made It is modern industry automatic technology in the application of field of household appliances, is the allusion quotation that household smoke exhaust ventilator field is developed to intelligent appliance field Type represents, and also represents the developing direction in kitchen appliance future to a certain extent, it is brief be exactly fashion this be from Modern Aesthetics viewpoint. Tobacco pipe can retract the structure in host when auto-lifting kitchen ventilator does not work, and realize the maximization of kitchen space, allow Kitchen is more succinct, naturally also more fashion.
But when being placed with the objects such as pots and pans below tobacco pipe, tobacco pipe declines automatically can meet these objects And it continues to decline, this is possible to that object is caused to damage, it is also possible to cause tobacco pipe even fume-exhausting ontology to break down, Its normal use is influenced, there are prodigious security risks.
Therefore, the research and optimization that a deep step how is carried out to the structure of existing range hood, make it overcome the above problem, It is those skilled in the art's problem urgently to be resolved hurrily.
Invention content
The utility model optimizes its elevating mechanism for deficiency present on current extractor hood structure, A kind of simple in structure, energy collision reaction, safe and reliable range hood elevating mechanism are provided.
To achieve the goals above, the utility model provides a kind of novel structure and technical solution:A kind of fume-exhausting Machine elevating mechanism, including range hood ontology and tobacco pipe lifting body, the fume-exhausting lifting body is along the range hood Ontology carries out oscilaltion, it is characterised in that:It is provided with rope between the range hood ontology and the tobacco pipe lifting body Rope, the range hood ontology are additionally provided with driving device, and the driving device drives fume-exhausting liter described in the cable traction It drops main body and carries out oscilaltion, rebounding device, rebounding device control when the rope loosens are provided on the rope The driving device is reversely drawn.
Specifically, the rebounding device includes stationary contact and movable contact, the stationary contact is fixedly installed on the fume-exhausting On machine ontology, the movable contact is movably set at the stationary contact, and the rope passes through the movable contact, the rope to draw The stationary contact and the movable contact contact when tight, the driving device by program setting rotation, when the rope loosens described in Stationary contact and the movable contact separate, and the driving device presses program setting reversion automatically.
As an improvement, range hood ontology both sides are additionally provided with pulley, the rope is led around the pulley Draw, the rope between pulley described in both sides is horizontal segment, and the rebounding device is set on the horizontal segment, and close to institute State pulley.By above structure, anyway the rope relaxation effect at device is best, while movable contact can be affected by gravity, So that the sensitivity of rebounding device is dramatically increased, improve the reaction speed of mechanism,
Preferably, the rebounding device is two, it is respectively arranged near the pulley of both sides.Ensure tobacco pipe liter Drop main body any position collides, at least one rebounding device can fast reaction.
As an improvement, it is additionally provided with guide rail between the range hood ontology and the tobacco pipe lifting body, it is described to lead Rail is fixedly installed on range hood ontology both sides.Lifting body tobacco pipe can be prevented its offset, be carried by rail guidance The stability of height lifting.
As an improvement, being additionally provided with upper stroke switch and lower stroke switch on the range hood ontology, institute is limited respectively State the maximum climb of tobacco pipe lifting body and maximum dropping distance.
Preferably, the rope is steel wire rope, the driving device is motor.
The beneficial effects of the utility model are:By the setting of rebounding device, make tobacco pipe lifting body accident collision object When body, can quickly rebound, its is avoided to damage object and tobacco pipe lifting body itself, improve the safety that uses of range hood and Reliability.
