The structure of present embodiment mechanical type dumping switch (16) is the epicoele (37) that connection is arranged in the housing (34), conical cavity (39) and cavity of resorption (38), the bottom of the epicoele (37) of housing (34) and the connected chamber of cavity of resorption (38) are conical cavity (39), microswitch (32) is housed in the cavity of resorption (38), the shell wall that the electric lug plate (36) of microswitch (32) passes housing (34) stretches out outside housing (34), switch feeler lever (33) position of microswitch (32) is over against conical cavity (39), heavy ball (31) is installed in the epicoele (37), the upper end accent of the epicoele (37) of loam cake (35) cap seal housing (34).
In the circuit of mechanical type dumping switch (16) electricity series connection thermocouple (4) and gas control valve (10).Connect the respectively display circuit of the display circuit of igniting microswitch (11), diode (D1), resistance (R), electric capacity (C), battery case (15) and operation indicating micro switch (9), diode (D2), resistance (R), electric capacity (C), battery case (15) of light emitting diode (22).Connect the accident extinguishing holding circuit of the magnetic valve of gas control valve (10) by thermocouple (4) electricity.
The outdoor heater control course of work
Ignition process.
Combustion gas is imported from inlet suction port (20), manually press the knob (12) of gas control valve (10), the magnetic valve of gas control valve this moment (10) is opened, interlock is simultaneously connected (K1) of igniting microswitch (11), pulse igniter (17) igniting, gas control valve is rotated counterclockwise 90 ° again, valve is in maximum open position, interlock is simultaneously connected (K2) of operation indicating micro switch (9), and combustion gas enters burner (2) through gas control valve (10), under the effect of high-voltage spark, combustion gas is lighted, this moment, flame burnt thermocouple (4), and the thermoelectrical potential that thermocouple produces enters the magnetic valve of gas control valve (10), when the flame of thermocouple induction arrives certain temperature, thermocouple (4) produces thermoelectrical potential, make magnetic valve remain on attracting state (electromagnetic valve is in open mode), hand leaves knob (12), and warmer enters normal operating conditions, when the manual adjustments anglec of rotation, can change the size of flame.
The light of duty shows.
When manually pressing (K1) that gas control valve (10) makes igniting microswitch (11) and connecting, battery (3 volts) is housed in the battery case (15), the positive pole of battery through igniting microswitch (11) and diode (D1) to light emitting diode (22) (LED), resistor (R) connects negative pole makes light emitting diode (22) (LED) luminous, show the existing combustion gas conveying of warmer, show to enter duty.At its linkage of gas control valve (10) inhour rotation (K2) of operation indicating micro switch (9) connected, light emitting diode (22) is (LED) luminous simultaneously.Igniting is finished, and (K1) of igniting microswitch (11) disconnects, and (K2) of work indication fine motion beginning 9 still remains on on-state, and light emitting diode (22) is (LED) still luminous.Light emitting diode adopts the light emitting diode of super brightness, be contained on the LED seat (13) that transparent engineering plastics make, be annular, have peep hole (30) on the knob (12), red or blue look luminous can be shown by peep hole, luminous bright eye-catching.Only when knob (12) dextrorotation went to the position of pass, (K2) of operation indicating micro switch (9) disconnected, and light emitting diode puts out bright because of outage.To reach the purpose that duty shows.
The accident extinguishing safeguard protection.
When outdoor heater in the course of the work if meet accident flame-out; the temperature of thermocouple this moment (4) induction descends; thermoelectrical potential is descended simultaneously; when dropping to uniform temperature; its thermoelectrical potential is reduced, cause magnetic valve not keep attracting state and discharge, electromagnetic valve is closed; make combustion gas not to external leakage, to play the safeguard protection effect of accident extinguishing.
The anti-safeguard protection of toppling over.
When heating cry placing or work in inclination has taken place; its angle of inclination is during greater than 15 ° of angles; its mechanical type that is installed in the warmer is toppled over microswitch (K3) disconnection of beginning (16); thermocouple this moment (4) is cut off to the electrical connection of the interior magnetic valve of gas control valve; the thermoelectrical potential signal of thermocouple (4) can not enter magnetic valve, makes magnetic valve outage and discharges closed electromagnetic valve; stop the burning of warmer, thereby play the safeguard protection effect of work when preventing the outdoor heater inclination.
Mechanical type is toppled over the beginning operation principle.
A, the beginning feeler lever (33) that is pressed in microswitch (32) when the bottom of heavy ball (31) are located, and it is depressed, and heavy ball (31) is supported in the housing (34) of the conical cavity (39) of epicoele (37) bottom and locates, and microswitch (32) electricity is connected.B, mechanical type dumping switch (16) tilt with warmer, when tilting to surpass 15 °, then mechanical type dumping switch (16) action, heavy ball (31) breaks away from the switch feeler lever (33) of microswitch (32), and be supported on the housing (34) of epicoele (37), beginning feeler lever (33) ejects and resets, and microswitch (32) electricity disconnects.
It is easy to operate to take the fuel cartridge bottle.Outdoor heater fuel cartridge bottle is placed in warmer bottom staving 25, support (27) internal support on base (26).In the time will placing or take out the fuel cartridge bottle, with hand staving (25), staving lid (24) are upwards started together, the fuel cartridge bottle be put or be taken out to a jar bottle then can into from the support surrounding space, and is easy to operate.Staving (25) also can be accomplished one with staving lid (24), and separately two is for the ease of processing and manufacturing.
