Abstract
The utility model relates to a control device of a liquid fuel furnace or a stove. The valve comprises an air valve, an oil valve, an igniter, a switch shaft, a fixing plate, a cam, a thumb wheel, a knob and the like, wherein the cam is arranged on the switch shaft, the highest point of the cam is in contact with a valve core of the air valve, and the thumb wheel positioned on the outer side of the cam is connected to a valve rod of the oil valve. The knob is turned to connect the gas valve first, and the gas valve is turned on to preheat via igniter and then closed for oil gasification combustion. It has simple structure, high heat efficiency and safe combustion. The danger of burning, fire and the like caused by opening the oil valve first and then opening the gas valve is avoided, the safety and the reliability are realized, and the content of CO in the flue gas meets the national emission standard.
Description
The utility model relates to the control device of a kind of liquid fuel furnace or kitchen range.
Commonly used liquid fuel cooker configuration gas, two switches of oil are controlled air valve, fuel tap respectively, drive fuel tap after must opening air valve earlier during use.If maloperation, will burn human body even cause fire of air feed behind the first fuel feeding, flame.Though and the liquid fuel cooker that has only a fuel tap has overcome the danger that maloperation causes, to just can reach normal combustion through two～five minutes after the igniting, the imperfect combustion CO content in smoke substantially exceeds national specified discharge standard, contaminated environment.
The purpose of this utility model provides a kind of Oil-burning range oil gas stacked switch, and is with switch control igniting, preheating and a burning, simple in structure, safe and reliable.
The purpose of this utility model is achieved through the following technical solutions: the connection of the cam control air valve on the switch shaft is housed and closes, the cam driven thumb wheel lags behind fuel tap and connects.Air valve is connected the back combustion preheater, connects the fuel tap fuel feeding and closes gas check valve again, reaches normal combustion.It is by air valve, fuel tap, igniter, switch shaft, knob and fixed head constitute, air valve (3), igniter (2), last plectrum (12), following plectrum (11) is connected in turn on the fixed head (1), switch shaft (4) is contained in the hole of fixed head (1), knob (5) and cam (6) are separately fixed at the two ends of switch shaft (4), the spool of air valve (3) contacts with the peak of cam (6), being positioned at the outer thumb wheel (7) of cam (6) is installed on the valve rod of fuel tap (8), deckle board (9) is fastened on the fixed head (1), stage clip (10) is enclosed within on the switch shaft (4), stage clip (10) one ends head on deckle board (9), and the other end is pressing plectrum (11), and last plectrum (12) one sides contact with igniter axle (13).
Turning knob (5), cam (6) rotates with switch shaft (4), when the peak of cam (6) contacts with the spool of air valve (3), the air valve spool is depressed, air valve (3) is opened ventilation, and plectrum (11) was stirred plectrum (12) under switch shaft (4) drove simultaneously, and it is traversing that last plectrum (12) promotes igniter axle (13), preheating is carried out in the igniter igniting.Be rotated further knob (5), the peak of cam (6) and air valve (3) spool are thrown off, tolerance reduces gradually, meanwhile, thumb wheel (7) is opened fuel tap (8) hysteresis 10～20 seconds with switch shaft (4) rotation under pin or key or pressing plate function, connects oil circuit, closes gas check valve, gasification of fuel oil burning, turning knob (5) are regulated oil mass to reach the best combustion operating mode.
The utility model has replaced existing gas, two switches of oil with an oil gas stacked switch, and the danger of fundamentally having avoided maloperation to bring is easy and simple to handle, safe and reliable.Because logical again oil, gasification, and combustion after first ventilation, igniting, the preheating, therefore thermal efficiency height has overcome the shortcoming of the Oil-burning range over-emitting black exhaust that has only a fuel tap, and CO content in smoke is 0.05% after tested, be lower than national specified discharge standard, reduced environmental pollution.
Accompanying drawing 1 is a kind of structural representation of the utility model.
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
With reference to accompanying drawing, fixed head (1), deckle board (9), upper and lower plectrum (12), (11) available metal plate are stamped to form, or suppress with ABS plastic.Igniter (2), air valve (3) are selected commercially available standard component for use.For avoiding fuel blow, improve dependability, fuel tap (8) is good to adopt rotating fuel tap.Bakelite knob (5) is fastened on the switch shaft (4) with pin or rivet.Cam (6) adopts pin or key or pressing plate to be connected with thumb wheel (7).The elastic force of stage clip (10) should make upper and lower plectrum (12), (11) rotate freely.
Claims (2)
1, a kind of Oil-burning range oil gas stacked switch, comprise air valve, fuel tap, igniter, switch shaft, knob, fixed plate part, it is characterized in that air valve (3), igniter (2), last plectrum (12), following plectrum (11) is connected in turn on the fixed head (1), switch shaft (4) is contained in the hole of fixed head (1), knob (5) and cam (6) are separately fixed at the two ends of switch shaft (4), the spool of air valve (3) contacts with the peak of cam (6), being positioned at the outer thumb wheel (7) of cam (6) is installed on the valve rod of fuel tap (8), deckle board (9) is fastened on the fixed head (1), stage clip (10) is enclosed within on the switch shaft (4), stage clip (10) one ends head on deckle board (9), and the other end is pressing plectrum (11), and last plectrum (12) one sides contact with igniter axle (13).
2, Oil-burning range oil gas stacked switch according to claim 1 is characterized in that cam (6) and thumb wheel (7) adopt pin or key or pressing plate to be connected.
