Abstract
The utility model discloses a gas range lighting and regulating device, comprising a nozzle, a valve, a locking mechanism, a pulse generator, a discharger, a positioning mechanism of a mini-type switch system and an end face cam. The utility model realizes the continuous pulse lighting of the gas range, the synchronization of gas and fire, the regulation of the gas flame size and the restriction of the small fire; the once suction volume of air is increased, making the gas sufficiently burn. The utility model has the advantages of high thermal efficiency and low cost, and is for the production of novel gas range or the reconstruction of the existing large quantity of the single fire hole gas ranges.
Description
The utility model relates to the igniting in a kind of combustion apparatus and the adjusting of burning.
At present, domestic a lot of still with simple eye simple and easy gas range, it is to be regulated by the straight-through valve of band handle, and adjustable range has only 90 °, does not have locking device and little fiery restraint device, out of controlly easily causes gas leakage with extinguishing; Must the limit during use open source of the gas, manually light with ignition source on the limit, troublesome poeration, gas leakage easily; The pore that does not have an air intake around the nozzle often causes that air imbibed quantity is not enough and burn incompletely is not only wasted but also dangerous.It is to adopt the piezoelectric ceramics automatic ignition device that a lot of gas ranges are now also arranged, but the rate of catching fire is not high, is to give vent to anger earlier yet, after go out spark, also easily gas leakage and price are more expensive, use wideless.
The purpose of this utility model provides a kind of igniting and adjusting device of cheapness, can make gas range improve security, finishes gas, fire synchronously, lights a fire automatically, and can realize the adjusting of flame.
The utility model is made up of microswitch system, detent mechanism, edge cam, nozzle, valve, locking mechanism.Microswitch system (14) is made up of push rod, interior outer spring, movable contact spring, fixed touching plate, switch base.One end of push rod is spherical, and the centre is a bit of to be step, and the other end is the garden cylindricality, and an obstructed centre bore is arranged, shock mount usefulness, and the both sides of centre bore have an obstructed keyway dress movable contact spring, and fixed touching plate is contained in the bottom land of switch base.Detent mechanism is by being fixed on the spring leaf (19) on the bracing strut (23) and being pressed in steel ball (18) under the spring leaf and the outer garden of edge cam (3) is formed with axle (1) four grooves in the same way, to igniting, control flame size, play the role of positioning when closing.Edge cam (3) one ends are curved surface, one end is the plane, a hole and a groove are arranged on the plane, cam is fixed in the middle of the axle (1), when axle (1) rotates, by the curved surface and the push rod Contact Transmission of edge cam (3), the duty of control microswitch system (14) makes pulse igniter (15) work.Two ends of nozzle (10) are the garden cylindricalitys for each one section, and be threaded, middle one section is hexagon, all there is aperture (air suction inlet) to communicate on every plane with the nozzle center hole, one end of nozzle (10) connects burner injection pipe end, compress with nut (9), the other end connects with valve shell, and valve, nozzle (10), burner are directly linked together.The cylindrical of nut (9) is a hexagon for one section, rises to turn to compress to connect and uses, and one section is garden shape, and air regulating board overlaps place, garden outside, can rotate in the outer garden of nut, regulates intake.Valve is made up of valve shell (8), spool (7), axle (1), bracing strut (23), connecting plate (22), inside and outside spring (5) (6).One section of valve shell (8) is the garden cylindricality, and one section is taper, and the adapter that has a connection combustion gas to use on the conical surface directly links to each other with air inlet pipe, in the gas cut-in valve; One section of spool is the garden cylindricality, and end face has groove by centre bore and coincide with the axle that puts in the spool, and one section is taper, vertical and the connection in two concentricity holes of the large and small aperture that differs is arranged on the conical surface, during rotation, can be over against the adapter of valve shell (8) conical surface, logical combustion gas; One termination knob of axle (1), the other end is that rectangle puts in the groove of spool, can drive valve core rotation, also can do axially-movable in groove; Connecting plate (22) is fixed on the valve shell (8), and the centre bore of the flange that it is dug and spool, axle are with the garden heart movingly.Spring leaf (19) one ends in the locking mechanism are fixed on the bracing strut (23) with rivet (17), the other end is fixed a pin (4), pin is by the hole on the bracing strut (23), when valve closing, just in time be inserted on the lock hole of edge cam plane one end, axle can not be rotated, play the locking action when closing.
The utility model is with low cost, can make gas range realize the continuous impulse igniting, the rate of catching fire reaches 100%, and can realize that the size adjustment of gas burner and little fire limit, and increase windproof property, improve security, increased the soakage of primary air, combustion gas is fully burnt, improve the thermal efficiency of kitchen range, the utility model can also be convenient to be used for transforming original a large amount of gas range as producing novel gas range.

During use, by knob and simultaneously to rotating counterclockwise, edge cam on the axle is by the order of rotating, broken away from the pin (4) on the spring leaf (2) of locking mechanism, axle is along with rotation, and the curved surface on the edge cam has promoted the push rod of microswitch, the impulse generator power connection, work immediately, produce continuous impulse by the discharger on the output lead end; Because the output high voltage pulse other end is connected on the burner, makes whole kitchen range form earth-return circuit, strong electric spark continuously takes place facing to the fire hole on the fire cover of burner in the tip of discharger. Simultaneously combustion gas is arrived again in the induction tunnel of burner by the spool that the rotates aperture to the nozzle, is lighted by electric spark immediately. Rotate knob to 90 °, another tongue on the week of edge cam garden drops on the steel ball again, the flame maximum, and at this moment, because the effect of edge cam, push rod is multiple, and microswitch cuts out to original position, and impulse generator quits work. If need to adjust flammule, can rotate counterclockwise again 90 °, at this moment because the effect of the groove on fixator pins (16) and another plane of edge cam has limited axle and can not transfer again, little fire keeps certain flame, has improved the wind-proof performance of little fire. When closing, clockwise rotate 180 °, be returned to original position, it is that knob can not rotate in the hole on one end of insertion end face cam plane that the pin on the spring leaf in the locking mechanism (4) is subjected to the elastic force effect. Detent mechanism is subjected to the steel ball of the spring leaf pressure groove that also falls, and valve is also closed.
