Description

Gas soldeirng iron

The invention belongs to a kind of soldering appliance of maintenance production applications such as circuit, plastics.

Do not have the instrument maintenance of electric outlying mountain area, geologic prospect, field work etc., all need to do without power supply the ferrochrome of the energy, some circuit welding as cmos circuit, for preventing the electrical breakdown to electric elements such as CMOS pipes, also needs to do without power supply the flatiron of the energy.

At present, once the someone proposed to adopt fuel gas to make the flatiron of the energy, for example: all using and making on the Gas Soldering iron and done big quantity research with No. 88212168 patents for No. 87207540, though this two invention goes out a research purpose together with the present invention, still has some problems in its structure and practical application.

1, both are air admission hole and steam vent concentrates in together these, and the air inlet convection current of giving vent to anger is not smooth, particularly No. 88212168 patents, adopt flatiron pipe and combustion chamber separate structure, two pipes all have row's air admission hole, and row's air admission hole concentrates in together, and this has more increased the difficulty of gas communication, supply oxygen.Cause gas fully not burn, produce flourishing and soot, and soot makes the inlet and outlet hole block again easily, cause difficulty to practical application;

2, when solder horn during (when this is welding necessary duty) towards the below, because the aperture, gas outlet of air supply pipe is big, the unburned gas flow velocity that flows out is low, and the high-temperature gas that burnt does not have a kind of suction force that it is taken away, so when air supply outlet is downward, the gas of flame heat expands, and the air-flow upward force is strong, causes Gas soldering iron oneself fire extinguishing;

3, the adjusting screw(rod) of No. 88212168 patent utilization perforation air storage chamber epicoeles, regulate air demand from flatiron handle rear portion with screwdriver, all will turn off pore has after hours destroyed the duty that has mixed up at every turn, therefore, the flow of fuel gas, each use all will readjust, operation inconvenience, preheating time is long, and consume fuel is many.

4, this invention also exists more material of complex structure needs and manufacturing procedure, shortcomings such as processing difficulties, cost height.

For solving the problem that exists in the above-mentioned prior art, the special spray odd test Gas soldering iron that proposes of the present invention.Solder horn (1) or (10) are installed in combustion chamber (2) front end that metal (copper, iron or stainless steel etc.) is made.Combustion chamber (2) itself is the flatiron pipe.Pipe thickness is generally 1.0-1.5mm; There is the combustion-supporting air admission hole of satisfying of distribution in a row at the tube wall middle part.Row's number, diameter and the position of aperture can be decided because of the size of flatiron.When for example combustion chamber (2) external diameter was the tubular of 14mm, aperture can adopt 8-12 row, the 7-10 circle, and diameter is that 0.8-1.5mm gets final product; There is the square orifice (9) of lighting and discharge waste gas the pipe front portion.Crucial is that air admission hole in a row will separate with bigbore exhaust square orifice (9), and a segment distance is arranged; The purpose that designs this structure is to make the convection current of turnover gas unimpeded, makes fuel gas mix fully burning with combustion-supporting gas; Make high-temperature gas through the porting convection current and in a segment distance just like producing a kind of suction force (jet power) like the chimney, cause flame no matter under the situation of any trend, all can be from breath.An air supply pipe that leads to handgrip liquefaction air chamber (6) is arranged in the combustion chamber (2), the pipe forward end seal, and open a jet aperture that in combustion chamber (2), sprays fuel gas less than 0.3mm.There is heat insulation joint (3) heat insulation between combustion chamber (2) and the handgrip liquefaction air chamber (6).Handgrip and liquefaction air chamber are one, constitute handgrip liquefaction air chamber (6).

What the present invention designed gives air cock (4) and gas flow adjusting means (5) in handle and flatiron pipe connection place, is two independently parts.When using for the first time gas flow is adjusted appropriateness, later on each application all needn't be gone adjusting again, opens switch and can use.

Figure describes the course of work in detail below in conjunction with this spray odd test Gas soldering iron.The concrete device details that proposes according to the present invention, this flatiron is made fuel with flammable liquid gasification butane etc.When switching device (4) when opening, the liquefaction body that handgrip liquefaction air chamber (6) stores is by flow regulator (5), and switching device (4) sprays into combustion chamber (2) through the aperture of air jet pipe.(2) square window (9) is located to light with fire in the combustion chamber, and fuel gas promptly is engraved in combustion chamber (2) internal combustion.Regulate flow regulator (5), when blue fire occurring, and with " z z z " during sound, fuel gas promptly reaches abundant fired state, in this state, solder horn about 20 seconds (1) just can dissolve scolding tin and weld.Also can utilize Boping solder horn (10) to melt plastics.When the liquefied gas in the handgrip liquefaction air chamber (6) uses up, can replenish liquefied gas from the inlet valve (7) at rear portion, guarantee that Gas soldering iron can use for a long time.Heat insulation joint (3) between combustion chamber (2) and the handgrip liquefaction air chamber (6) is heat insulation, guarantees work safety.

It is to adopt single cavity configuration that odd test Gas soldering iron characteristics are sprayed in the present invention, and combustion chamber and flatiron pipe are one, and air inlet separates with exhaust outlet, and a segment distance is arranged.Cause swabbing action, thermal current is impacted to solder horn, come the heating iron head with this just like chimney.The air admission hole of branch in a row, can guarantee abundant oxygen supply gas, and fuel gas such as butane burnt fully from fully the mixing with the suction gas of air inlet less than ejection 0.3 millimeter the aperture of air supply pipe, flame reaches Lan Se and z z z sound is arranged, the purpose of the speed heat that reaches a high temperature.And exhaust outlet is square big mouthful, makes the gas of expanded by heating can very fast eliminating, is unlikely the congestion affects burning.Therefore be not subjected to flatiron aspect effect up down after the burning of the Gas soldering iron of this spray odd test, be not afraid of wind, more adapt to welding job and field work.

The air cock (4) of giving that the odd test Gas soldering iron is sprayed in the present invention separates with gas flow adjusting means (5), is two independent parts.When Gas soldering iron after adjustment reaches operate as normal, promptly keep this good adjustment state, be unlikely because close to air cock (4) and destroy after finishing using.The time spent is readjusted again not need the second time.

The present invention uses proof through nearly time more than 2 years in tens of tests and the real work, and preheating time is short, not because of disposing way changes duty, good stability, welding effect is good, safe and reliable, not only can weld with scolding tin, and can the processing plastic goods.
