Preheating devcie for liquid fuel cooker

The utility model relates to a kind of preheater of liquid fuel cooker.

The existing cooking stove that uses liquid fuel, direct combustion of liquid fuel heating generating tube is adopted in the preheating of its liquid fuel mostly, this preheating method is easy to generate flourishing and black smoke, more obvious when particularly burning the high heating value liquid fuel, though also have some liquid fuel cookers also to adopt some smoke consuming apparatuses, flourishing and black smoke still appears in cooking stove combustion system easily under the temperature condition with higher.

The purpose of this utility model provides a kind ofly can control preheating with liquid fuel flow and combustion efficiency preheating devcie for liquid fuel cooker preferably.

Task of the present utility model realizes with following mode: a kind of preheating devcie for liquid fuel cooker, be fixed with cover on the preheating body, through hole one end in the preheating body is equipped with the control joint, the other end flow-control bar of packing into, the awl point of flow-control bar is facing to the end face of control joint, collar nut is connected woven hose with the control joint, in the woven hose other end introduced cover, joint is contained on the preheating body, through hole in it is connected with the through hole of preheating body, on the uncovered cylindrical periphery-wall of cover air admission hole is arranged.Also can be equipped with in the preheating body and fill out bar, the hole of filling bar forwardly has intercommunicating pore to be connected with the hole of dress flow-control bar, and joint is contained on the preheating body, and the through hole in it is connected at the rear portion with the hole of filling bar.Air admission hole is the combination in hole or slit or hole and slit.The material of making preheating body and flow-control bar is the material of two kinds of different linear expansion coefficients, and the line of material coefficient of expansion of flow-control bar is bigger than the line of material coefficient of expansion of preheating body.

The utlity model has simple in structure, the preheated liquid flow can be controlled, fuel combustion efficiency does not well produce flourishing and black smoke, characteristics such as easy to use, reliable, is suitable for the preheater of making liquid fuel cooking range.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Embodiment one

Cover 1 is one and is bent into the uncovered tin of a no end with sheet metal, be furnished with 150 to 200 air admission holes 13 on the perisporium of tube.Cover 1 is fixed on on steel or the castiron preheating body 2, flow-control bar 3 is screw rods of a band awl point, and its spinning is in the through hole of preheating body 2, and locking locknut 5 is spun on the control joint 4, control joint 4 is spun in the through hole of preheating body 2, and locking locking nut 5.Collar nut 6 is fixed on woven hose 7 on the control joint 4.Joint 9 is tightened on the preheating body 2.Spray point 8 is fixed on the preheating body 2.Woven hose 7 terminations are stretched in the cover 1.Through hole in the joint 9 is connected with the through hole of preheating body 2 dress flow-control bars 3.Flow-control bar 3 is screw rods of a band conehead, and its awl point faces the aperture of control joint 4.The through hole of preheating body 2 is straight-through screws.

Embodiment two: its structure is identical with embodiment one major technique feature, for further making the time of staying lengthening of preheated liquid on preheating body 2, make pre-heat effect better, on the preheating body, increase an endoporus in order to filling bar 10, this hole afterbody (promptly filling out the bar afterbody) is connected with joint 9 endoporus on being contained in preheating body 2, and this hole head (promptly filling out club head) has intercommunicating pore 14 to be connected with the holes of dress flow-control bars 3.

Cover 1 is one and is bent into the uncovered tin of a no end with sheet metal, be furnished with 20 to 150 air admission holes 13 on the perisporium of tube.Cover 1 is fixed on on steel or the castiron preheating body 2, and flow-control bar 3 spinnings are in the through hole of preheating body 2, and locking nut 5 is spun on the control joint 4, and control joint 4 is spun in the through hole of preheating body 2, and locking locking nut 5.Collar nut 6 is fixed on woven hose 7 on the control joint 4.Fill out in the hole that bar 10 is contained in preheating body 2, its afterbody is equipped with joint 9, and its head has intercommunicating pore 14 to be connected with the holes of dress flow-control bars 3.Spray point 8 is fixed on the preheating body 2, and woven hose 7 terminations are stretched in the cover 1.Screw 11, screw 12 are used for stopping up machining hole.

Flow-control bar 3 flows through liquid fuel with to fill out bar 10 all gapped with its installing hole in the gap.

Use: with reference to accompanying drawing 1,2,5, be embodiment one, during the kitchen range preheating, pre-heating fuel enters from joint 9, slit and woven hose 7 that aperture on the conehead of flow-control bar 3 and control joint 4 forms enter in the cover 1, and spray point 8 carries out preheating to the ignited fuel that enters in the cover 1 to the generating tube (accompanying drawing does not mark, and omits) that kitchen range are contained in the preheater top, because cover has a lot of air admission holes 13 that replenish air on 1, so over-emitting black exhaust and flourishing can well eliminate fuel combustion the time.During preheating, whole preheater also obtains adding ripe, when the fiery normal combustion of master, also can heat preheater.As after closing main fire, need again to continue again to use, preheater temperature this moment is than higher; at once if pre-heating fuel enters cover 1 very soon, fuel can be vaporized after running into hot preheating body 2 at once, produces a large amount of fuel vapours, cover 1 can not in time replenish a large amount of air, flourishing and over-emitting black exhaust can occur.So preheating this moment will slowly enter in the cover 1 with fuel, fuel flow rate must reduce, after the preheater temperature raises, the preheating body 2 that flow-control bar 3 that copper material is made and steel are made produces linear expansion simultaneously, because the linear expansion coefficient of flow-control bar 3 is greater than the linear expansion coefficient of preheating body 2, so the linear expansion amount of flow-control bar 3 is greater than preheating body 2, thereby formed slit diminishes between the awl of flow-control bar 3 point and the control joint 4, the pre-heating fuel flow reduces, and has played the purpose that varies with temperature automatic control pre-heating fuel flow.The height of control temperature can be adjusted by the size of regulating the initial slit between flow-control bar 3 and the control joint 4.

With reference to accompanying drawing 3,4,6, total use is basically with above-mentioned identical.Its difference is just can enter the sharp slit that forms with the aperture of controlling on the joint 4 of awl of flow-control bar 3 again in woven hose 7 enters cover 1 through intercommunicating pore 14 again pre-heating fuel enters the gap that will form through the endoporus of filling out bar 10 and preheating body 2 earlier from joint 9 after.Thereby liquid fuel long flow path on burner body 2, be subjected to preheating time longer, the preheated liquid temperature is comparatively high, helps burning.
