Description

Guarantee that liquid fuel can clean-burning igniting feeding system

The utility model relates to a kind of and the supporting novel igniting feeding system of liquid fuel cooking range, belongs to the technical field of the components and parts manufacturing of liquid fuel cooking range.

By the retrieval and the market survey of each side, existing liquid fuel cooking range mainly contains following components: burner part, valve part, bunkering supply section (containing valve), ignition section etc.This two part of burner and valve, improvement and perfect constantly, and igniting and feeding device but do not obtain having attention, style is consistent for many years.Igniter commonly used at present mainly is the pulse sparking: the ignition lead of igniter is communicated to the ceramic ignition head, and the ceramic ignition head stretches in the burner, and comes adjusting position and fixing by the screw of burner bottom; The return line of igniter is connected to (or being attached thereto on other metal parts of knot) on the burner; Ignition switch is installed on the handle of fine tuning valve.This class igniter more or less has following defective: often can not disposable fire fuel, and cause the fuel in the burner to overflow; Igniter head easily is moved, misplaces, and causes that igniter work power consumption is excessive, transformer easily burns etc.And the bunkering feeding mechanism, now substantially all used stress-free horizontal feed mode, the burning container has built-in, external, wall-hanging etc., but all is directly to draw a fuel discharge nozzle from the bottom of fuel tank, discharge nozzle stretches in the burner by behind the fine tuning valve.This class device also has certain defective: the big or small bad control of the pressure in the fuel discharge nozzle; Fine tuning valve is difficult for grasping to the large and small fire control lag in the burner; Fuel surplus that the valve accent is big, it is insufficient to burn, and has not only wasted fuel, even fuel can overflow initiation fire; Valve has been turned undercharge down, the phenomenon that flame is too small or have only one side of something to catch fire can occur.So along with the increase of the market demand, the igniting feeding system also utmost point needs to improve.

The purpose of invention of the present utility model provides a kind of energy and guarantees disposable igniting success, and fuel can not regulated obviously by excessive, big or small flame in combustion process, and the assurance liquid fuel can clean-burning igniting feeding system.

The utility model is to realize like this.Near on the outer cover of bottom, be welded two mutual approaching igniter head fixators and discharge nozzle fixator are with fixing of the position that guarantees ignition point and discharging point at burner.The fuel discharge nozzle is installed master switch valve and Regulation Control valve when fuel tank is drawn, in order to the outflow of control fuel and the discharging pressure of adjusting discharge nozzle; The other end of discharge nozzle stretches in the combustion chamber of burner, and is fixed by the discharge nozzle fixator after being communicated with fine tuning valve; The handle of fine tuning valve is installed on the kitchen range panel, and indicates scale usefulness, to regulate the liquid outlet quantity that flows into the liquid fuel in the burner.The ignition lead of igniter is fastened on the ceramic igniter on the burner, and the ceramic igniter other end and a built-in wire of lifting one's head stretch in the combustion chamber of burner together; The return line of igniter is connected on the fuel tank or other can be connected on the metal parts of burner on the kitchen range; Igniter is drawn the switch of two parallel connections, and a microswitch that is mounted on the fine tuning valve handle when the turn inching switch, produces the pulse sparking; Another hand that is mounted on the kitchen range face is pressed switch, after with the hand pressing, and can the long-time continuous igniting.

The advantage of invention of the present utility model is as follows:

1, owing to adopted the design of be welded igniter head fixator and discharge nozzle fixator, guaranteed ignition point and discharging point position stability, do not misplace, do not move, prevented discharging point skew, " be drowned " igniter head and prevent that ignition point from misplacing misfires or increases the igniter power consumption.

2, owing to adopted the design that the master switch valve is installed, prevented corrosion and the obstruction of fuel, prevented the accidental release of fuel components and parts such as valves.

3, owing to adopted the design that the Regulation Control valve is installed, make the fuel pressure in the discharge nozzle even, make things convenient for fine tuning valve to regulate the fuel quantity that flows in the burner, big or small duration and degree of heating is regulated obviously, played the equal effect of the pressure-reducing valve on the cylinder for liquefied gas.

4, owing to adopted the design of igniter dual ignition switch, prevented from when feed, to misfire, caused the possibility that burning is insufficient and fuel is excessive; Even at severe winter and wet season, also can guarantee the success of once lighting a fire.

Be described in detail enforcement of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the igniting feeding system of liquid fuel cooking range

Fig. 2 is the structural representation of the burner of liquid fuel cooking range

Comprise among the figure: igniter 1, ignition lead 1-1, return line 1-2, ceramic ignition head 1-3, wire 1-4, microswitch 1-5, hand are pressed switch 1-6, fuel tank 2, master switch valve 2-1, Regulation Control valve 2-2, fine tuning valve 2-3, discharge nozzle 2-4, burner 3, combustion chamber 3-1, outer cover 3-2, igniter head fixator 3-3, discharge nozzle fixator 3-4.

Specific implementation method is as follows: in the kitchen range shell of kitchen range, and built-in combustion device 3, igniter 1 and fine tuning valve 2-3, fuel tank 2 and master switch valve 2-1, Regulation Control valve 2-2 can be designed to built-in, or are designed to back-positioned type, wall-hanging.At the outer cover 3-2 of burner 3 position, approaching be welded igniter head fixator 3-3 and discharge nozzle fixator 3-4 mutually near the bottom.The ignition lead 1-1 of igniter 1 connects ceramic ignition head 1-3, and the end that the built-in wire 1-4 of ceramic ignition head 1-3 lifts one's head stretches in the combustion chamber 3-1 of burner 3, and is fixed by igniter head fixator 3-3; Return line 1-2 tipping on fuel tank 2. or tipping on the kitchen range can with burn on other metal parts that device 3 is connected to; Igniter 1 is drawn two in parallel switches: be installed in microswitch 1-5 on the handle of fine tuning valve 2-3 and the hand that is installed on the kitchen range panel and press switch 1-6.A discharge nozzle 2-4 is drawn in the bottom of fuel tank 2, and master switch valve 2-1, Regulation Control valve 2-2 and fine tuning valve 2-3 are installed on discharge nozzle 2-4 successively, and wherein the handle of fine tuning valve 2-3 is installed on the kitchen range panel, and indicates scale; Discharge nozzle 2-4 is in extending into the combustion chamber 3-1 of burner 3, and 3-4 fixes by the discharge nozzle fixator.

Concrete using method is as follows: before use, open master switch valve 2-1, what of the fuel in the based on fuel case 2 regulate Regulation Control valve 2-2.During use, turn fine tuning valve 2-3 makes fuel pass through discharge nozzle 2-4 to the combustion chamber of burner 3 3-1 feed; In rotary fine adjustment valve 2-3, handle touches microswitch 1-5 (in the winter time or other is when being difficult for fire fuel, can be before feed, first pressing hand is pressed switch 1-6, long-time sparking, guarantee disposable the lighting of fuel energy), igniter 1 is started working, and the wire 1-4 of ceramic ignition head 1-3 produces pulse spark, fire fuel in the 3-1 of combustion chamber, flame the size and close, 2-3 controls with fine tuning valve.Design of the present utility model has guaranteed that fuel can disposable lighting, and has guaranteed that institute's flow fuel that supply is moderate, and sufficient combustion, large and small fire are regulated obviously, do not have excessive fiery, phenomenons such as half of fire.
