Enter in water tank.In control circuit: at work, when the intracorporal water temperature of shell is lower than 50 DEG C, thermistor RT resistance value is in
The 12V DC power supply of higher state, voltage regulator circuit IC output enters tri- pole NPN after thermistor RT, adjustable resistance RP decompression
The base stage of pipe Q1 is lower than the 0.7V starting voltage of NPN triode Q1, tri- pole NPN into the base voltage of NPN triode Q1 this moment
Pipe Q1, PNP triode Q2 are in off state, relay J2 is in its control power input of power loss stop working state and normal
Open tip side disconnection；Due to relay J2 normally opened contact end and water pump M, two electromagnetic water valve DC1 and DC2 cathode power supply inputs
End is connected by conducting wire, and water pump M, two electromagnetic water valve DC1 and DC2 negative power supply input terminals and voltage regulator circuit IC negative power supply are defeated
3 foot of outlet is connected by conducting wire, so, water pump M, two electromagnetic water valve DC1 and DC2 meeting power loss stop working (of the invention this moment
For the first time in use, operator opens power switch S, the both ends thermistor RT are made to be in short circuit state, in this way, even if shell
Intracorporal temperature is lower than 50 DEG C, and thermistor RT resistance value is in higher state, but connects since the both ends thermistor RT are in
Logical its resistance value of state is zero, then the 12V DC power supply of voltage regulator circuit IC output is after adjustable resistance RP decompression, into NPN
The base voltage of triode Q1 can be higher than the 0.7V starting voltage of NPN triode Q1, then, NPN triode Q1, PNP triode
Q2 successive conductive, relay J2 be in work once electrified state its control power input be connected to normally opened contact end；Due to relay
Device J2 normally opened contact end is connected with water pump M, two electromagnetic water valve DC1 and DC2 cathode power supply input terminals by conducting wire, so, this
It carves two electromagnetic water valve DC1 and DC2 meeting its inner spool of work once electrified to open, water pump M meeting work once electrified takes out the water in water tank
Enter in outer housing and radiates for welding gun；After entering water in outer housing, operator closes power switch S, this moment if in outer housing
Water temperature be lower than 50 DEG C, relay J2 can power loss stop working, then, water pump M, two electromagnetic water valve DC1 and DC2 power loss stop
Work, its inner spool can close after two electromagnetic water valve DC1 and DC2 power loss stop working, not into the water inside outer housing
It can flow out, ensure that the heat dissipation of welding gun).In control circuit: at work, when the intracorporal water temperature of shell is higher than 50 DEG C, temperature-sensitive
Resistance RT resistance value is lower rapidly, and the 12V DC power supply of voltage regulator circuit IC output is after thermistor RT, adjustable resistance RP decompression
Into the base stage of NPN triode Q1, originated this moment into the 0.7V that the base voltage of NPN triode Q1 is higher than NPN triode Q1
Voltage, then, NPN triode Q1, PNP triode Q2 be in the conductive state, relay J2 is in obtain electric attracting state its control
Power input is connected to normally opened contact end；Due to, relay J2 normally opened contact end and water pump M, two electromagnetic water valve DC1 and
DC2 cathode power supply input terminal is connected by conducting wire, water pump M negative power supply input terminal and voltage regulator circuit IC negative power supply output end 3
Foot is connected by conducting wire, so, water pump M, two electromagnetic water valves DC1 and DC2 understand work once electrifieds, two electromagnetic water valve DC1 this moment
And DC2 inner spool is opened, the water of water pump M extraction enters in outer housing to radiate for welding gun.By the above, the water temperature in outer housing
When lower than 50 DEG C, water pump M and two electromagnetic water valve DC1 and DC2 meeting power loss stop working, and water temperature is higher than 50 DEG C in outer housing
When, water pump M and two electromagnetic water valves DC1 and DC2 understand work once electrifieds, make to be always maintained at water state inside outer housing, water temperature one
It is straight to be in 50 DEG C hereinafter, effectively radiating for welding gun.
Shown in Fig. 2, in control circuit: when there is water in water tank, water floods two copper bars T1, T2, NPN triode Q1 base
Pole obtains power supply conducting, then, PNP tri- from voltage regulator circuit IC power output end anode through resistance R1, water, two copper bar T1 and T2
Pole pipe Q2 conducting, relay J1 obtain electric actuation, and it controls power input and the disconnection of normally-closed contact end；When water level reduces in water tank
When, water cannot flood copper bar T1, T2, and NPN triode Q1 base stage cannot be again through resistance R1, water, two copper bar T1 and T2 from steady
Volt circuit power output end anode obtains power supply conducting, and then, PNP triode Q2 cut-off, relay J1 power loss stop being attracted it
Control power input and normally-closed contact end closure；Due to relay J1 normally-closed contact end and the input of buzzer XX cathode power supply
End connection, buzzer XX negative power supply input end grounding, so, cistern water level is reduced to when cannot centainly flood water pump M, after
Electric appliance J1 power loss stops after being attracted its control power input and normally-closed contact end closure, and buzzer XX can issue loud alarm
Sound, giving that user's prompting water level is too low should in time plus water.The present invention can effectively radiate for welding gun, moreover it is possible to control water pump M
Working method reach energy-efficient purpose, user can also be notified when water level is too low, thus have good application prospect.
