Fig. 2 is of the present utility model bleeding and the structural representation of flue gas processing device.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is done into an explanation.
As Fig. 1, shown in 2, a kind of smoke abatement electric iron, by electric iron, smoke removal conduit, bleeding forms with flue gas processing device, register.
As shown in Figure 1, electric iron part is mainly by suction head 2, flue 3, infrared sensor 4, wire 5, electric iron handle 6, flue adapter 7, electric soldering bit 8, temperature sensor 9, heating core 10, terminal 11.
Flue 3 front ends are provided with suction head 2, and electric soldering bit 8 is equipped with in inside, and electric soldering bit 8 rear ends connect heating core 10, and flue is equipped with electric iron handle 6 outside 3 rear ends, and is connected and bleeds and flue gas processing device with smoke removal conduit by flue adapter 7.Register comprises temperature sensor 9, microprocessor, and temperature sensor 9 is arranged on electric soldering bit 8 outsides, and connects heating core 10 by microprocessor.An infrared sensor 4 is installed on handle 6, and infrared sensor 4 is connected respectively and is bled and flue gas processing device and electric iron power switch by microprocessor.
Electric soldering bit 8 and heating core 10 are mainly for generation of the required heat of welding, and suction head 2 and flue 3 are for forming fume extractor.Flue 3 via smoke removal conduit be connected to bleed with flue gas processing device on, and in suction head 2 place's draw gas, because suction head 2 entirety are annular design, the gas that therefore absorbed can form the smoking conical envelope surface 1 of a sealing around electric soldering bit.Like this, no matter flue gas from which direction is emerged, sucked and all will pass through this smoking conical envelope surface 1 by human body if wanted, the negative pressure producing when air-breathing for getter device due to this smoking conical envelope surface 1 again causes, therefore when flue gas arrives this smoking conical envelope surface 1, can enter suction head 2 along this smoking conical envelope surface 1, and via flue 3 suck bleed with flue gas processing device in, thereby arrived the effect that prevents that flue gas is excessive.In addition, whether infrared sensor 4 is using electric iron for detection of operating personnel, in the time that infrared sensor 4 detects that operating personnel are using electric iron, can send this signal to microprocessor, by microprocessor control fume removal system automatic operation.
Smoke removal conduit is mainly used in connecting the flue of bleeding with flue gas processing device and electric iron inside, needs the often position of conversion electric iron during due to soldered circuit board, can select flexible pipe for the ease of bending.In addition, after considering that this device is long-time and using, may in hose wall, leave some flue dust, for the ease of changing smoke removal conduit, can be by this conduit and current supply line separately, and with line Qia also together.
Register can arrange electric iron temperature, on register, set temperature required after, in heating core 10 by electric current start heating, meanwhile, be positioned at the temperature at temperature sensor 9 these places of Real-time Collection at electric soldering bit place.In the time that electric soldering bit 8 temperature reach design temperature, microprocessor is the electric current that reduces to flow through in heating core, thereby reaches the effect of equilibrium temperature.In addition, when microprocessor detects electric iron used time not for a long time by infrared sensor 4, will carry out power down process to heater, prevent the head oxidative damage causing because of the long-time dry combustion method of electric iron.
As shown in Figure 2, bleed and flue gas processing device, mainly formed by flue adapter 12, flue gas concentration sensor 13, one-level extraction fan 14, adsorbent equipment 15, secondary extraction fan 16, tail gas interface 17 etc.Flue adapter 12 rear ends connect flue gas concentration sensor 13, one-level extraction fan 14, adsorbent equipment 15, secondary extraction fan 16, tail gas interface 17 successively.
Bleed with flue gas processing device for the generation of negative pressure and the processing of flue gas.Wherein flue gas concentration sensor 13 is for detection of flue gas concentration, and sends this flue gas concentration to microprocessor, and microprocessor is according to the rotating speed of the automatic bleeding regulating fan of flue gas concentration.Because flue gas will pass through adsorbent equipment, therefore the speed of its discharge is slower, in order to address this problem, in the utility model, use two-stage extraction fan, the rotating speed of secondary extraction fan is set to 1.5 times of one-level extraction fan rotating speed all the time, thereby the both sides that ensure adsorbent equipment exist a draught head all the time, and then ensure smooth suction and the discharge of flue gas.Flue gas through flue gas adsorption device has reached discharge standard, can directly discharge, or one conduit is installed by outside its discharge chamber at tail gas interface.
Use procedure of the present utility model:
In the time that operating personnel use electric iron, first on temperature adjustment panel, set the temperature of wanting, heating core 10 starts heating afterwards, electric soldering bit 8 temperature rises, when detecting electric soldering bit 8, temperature sensor 9 arrives after the temperature of setting, microprocessor will utilize little electric current to heat electric soldering bit 8, makes the temperature of electric soldering bit 8 be maintained design temperature.In the time that staff picks up electric iron, the infrared sensor 4 being positioned on electric iron handle 6 detects that operating personnel are using electric iron, and send this information to microprocessor, microprocessor control extraction fan 14,16 is worked, thereby around electric soldering bit 8, produces the conical envelope surface 1 of a negative pressure.The flue dust producing in welding process enters suction head 2 along this enveloping surface while arriving enveloping surface 1, after flue 3, flue adapter 7, smoke removal conduit, flue adapter 12, flue gas concentration sensor 13, one-level extraction fan 14, adsorbent equipment 15, secondary extraction fan 16, is discharged by tail gas interface 17.Meanwhile, be arranged in the smokescope sensor 13 of bleeding with flue gas processing device and can also detect smokescope, by the rotating speed of microprocessor control extraction fan 14 and 16, the higher rotation speed of the fan of concentration is faster.In addition, in the time that infrared sensor 4 detects that electric iron does not use for a long time, microprocessor will be controlled heater power-off, prevents the oxidative damage that long-time dry combustion method causes electric soldering bit.
