Embodiment 1
[0040] An inverter manual welding machine, such as figure 1 with figure 2 As shown, it includes a housing 100 and a circuit board structure disposed in the housing 100 , and the housing 100 is provided with cooling holes 110 .
[0041] figure 2 Among them, the circuit board structure includes a main circuit 210 , a temperature control circuit 220 and a backup power supply device 230 .
[0042] Such as image 3 As shown, the temperature control circuit 220 includes a number of temperature sensors 221 , a signal processor 222 , and a driver 223 , and the driver 223 is connected to a speed-regulating fan 300 . In this embodiment, three temperature sensors 221 are selected, each temperature sensor 221 is connected to the signal processor 222, the signal processor 222 is connected to the driver 223, and the driver 223 is connected to the speed-regulating fan 300. The three temperature sensors 221 can be configured according to the housing 100, They are respectively arranged a...
Embodiment 2
[0052] An inverter manual welding machine, such as Figure 5 As shown, including Embodiment 1, the difference from Embodiment 1 is that each temperature sensor 221 is provided with a timing switch circuit 400, and the timing switch circuit 400 is used to control the temperature sensor 221. connected. The power of the temperature sensor 221 can be effectively saved by the intermittent operation of the timing switch.
[0053] The timer switch circuit 400 includes a functional circuit mainly composed of a chip IC555. The timing switch circuit 400 specifically includes resistors R11, R12, R13, capacitors C11, C12, a transistor Q11, and a relay KM2. through as Image 6 After the voltage Vcc is energized, the pin 3 of the chip IC555 outputs a high level at intervals, thereby driving the transistor Q11 to conduct, so that the relay KM2 is energized, and the temperature sensor 221 works.
Embodiment 3
[0055] An inverter manual welding machine, such as Figure 9 As shown, the difference with the above-mentioned embodiments 1 and 2 is that: the input terminal of the main circuit 210 is connected with a human body sensing circuit 500, and the human body sensing circuit 500 includes a human body infrared sensor 510, a judgment circuit 520, and a switching circuit 530 connected in sequence, and the human body infrared sensor 500 is sequentially connected. The sensor 510 is used to sense the human body signal and convert it into an electric signal. The judgment circuit 520 judges whether the human body enters the set sensing range according to the electric signal of the human body infrared sensor 510. The switching circuit 530 is used to close the contact when the human body enters the set sensing range. Connect the input line of the main circuit 210, otherwise keep the input line of the main circuit 210 disconnected.
[0056] Sensing whether the human body enters the sensing ran...
