Description
The utility model relates to a kind of pulse firing controller, and it is used for the IGNITION CONTROL of high-tension electricity spark pulse discharges such as combustion gas tool.
Existing pulse firing controller is all controlled by microswitch, and microswitch directly is connected in the pulse firing control circuit, when closed microswitch, and the work of contact conducting pulse firing controller, the combustion gas in the burning appliance is given me a little in the high-voltage cable discharge.Because the contact of microswitch and microswitch are difficult for sealing with the contact that connects lead, and contain composition in the combustion gas to switch contact, contact corrosion, easy just contact oxidation, cause poor contact of contacts, cause electric leakage easily after the pollutions such as contact laying dust, so when using in rugged environment, said structure can cause the reliability of switch motion to reduce.Microswitch directly is connected to circuit, and it is big to flow through electric current, and operating mechanism need be done the contact mechanical movement when contact endurance reduction and microswitch action, has increased the operation resistance, the also corresponding complexity of structure.
The purpose of this utility model be the deficiency that exists at existing product and provide a kind of can be in adverse circumstances such as greasy dirt, steam, combustion gas be arranged still can reliably working, the gauge tap long working life, and assembly structure is simple, the little pulse firing controller of operation resistance.
The utility model is to realize like this, this pulse firing controller comprises shell, cased circuit board, the high-voltage cable that end is electrically connected takes place with the circuit board high pressure, circuit board has the contact that is used for the power supply connection, it is characterized in that also comprising magnet proximity switch, and magnet proximity switch is electrically connected with the circuit board control end with drawing lead, magnet proximity switch is sealed in the switch cover with the contact of drawing lead, magnet proximity switch by magnet near or magnet move away from magnet proximity switch.
Magnet proximity switch of the present utility model can be the magnetosensitive switch; reed switch; or the switch that depends on changes of magnetic field to move such as hall-effect switch; can one or several be set respectively according to control needs magnet proximity switch of the present utility model and high-voltage cable; circuit also can be arranged to the energized of delaying time; band ion probe blowout protection formula, or band drives electromagnetic type etc.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is a kind of on-off circuit schematic diagram of the utility model magnet near the nearly switch work of magnetic.
Fig. 3 is a kind of on-off circuit schematic diagram of the utility model magnet away from magnet proximity switch work.
Fig. 4 is a kind of on-off circuit schematic diagram of the utility model magnet away from the magnet proximity switch delay working.
Circuit board in Fig. 1 (2) is contained in the shell, end G takes place and is electrically connected in the same circuit board of high-voltage cable (3) (2) high pressure, magnet proximity switch (4) is sealed in the switch cover (6) with fluid sealant with the contact of drawing lead (5), circuit board (2) has joint a, b to be used to connect power supply, also battery case can be set with what dry cell was made power supply in shell.Switch cover (6) can be made of plastic.The available magnetosensitive switch of magnet proximity switch (4), reed switch or hall-effect switch etc. when control supply voltage during 3 volts or 1.5 volts, select for use the reed switch that do not need power work for well.
Magnet proximity switch (4) can directly replace microswitch to be used.In order to reduce switching current, increase service life, simultaneously for the needs of control mode, the control end that magnet proximity switch (4) also can same switching transistor (T) is electrically connected as electronic switch and uses, and the same circuit board of switching transistor (T) output (2) control end is electrically connected.
Switching transistor of the present utility model (T) can be three end control elements such as triode, FET, controllable silicon.
As Fig. 2, switching transistor (T) is used triode, magnet proximity switch (4) is used reed switch, its cross-over connection is in the control end B and current-limiting resistance (R) end of triode (T), the same circuit board of current-limiting resistance (R) (2) power connection a is electrically connected, and the output C of triode (T), E cross-over connection are in circuit (2) control end N and earth terminal b.When magnet (S) during, reed switch (4) closing of contact near reed switch (4), triode (T) conducting, high-voltage cable (3) discharge of end G by being electrically connected with it takes place in circuit working, circuit board (2) high pressure.
As Fig. 3, switching transistor (T) is used FET, and magnet proximity switch (4) is used hall-effect switch, and hall-effect switch (4) power end F is connected to circuit board (2) power connection a, and its output M, J cross-over connection are in earth terminal b and resistance (R) and resistance (R
1) between the contact, resistance (R) and resistance (R
1) respectively with power connection a, the B of FET (T) holds electrical connection, FET (T) output C, E cross-over connection are in circuit board (2) control end N and earth terminal b.When magnet (S) during near hall-effect switch (4), M, J hold conducting, adjust resistance (R) and make and flow through M, J end electric current at microampere order, and at this moment FET (T) ends.When magnet (S) during away from hall-effect switch (4), M, J end ends, FET (T) conducting, and high-voltage cable (3) discharge of end G by being electrically connected with it takes place in circuit board (2) high pressure.
Use FET as Fig. 4, switching transistor (T), magnet proximity switch (4) is used reed switch, and reed switch (4) is connected to resistance (R) and electric capacity (C
1) contact and earth terminal b, electric capacity (C
1) the same FET of the other end (T) B end and resistance (R
