Description

Heat gun

The utility model belongs to the heating firing equipment.

At present, for the local heat at the engineering truck of severe cold area field work, and open-air tent and heating of house do not have desirable equipment, gives field work, camps and bring inconvenience.

The purpose of this utility model provides a kind of convenience, flexible, reliable air-heater to solve the above-mentioned problem that exists.This air-heater can be widely used in the local heat when construction such as severe cold area field work vehicle.As to the vehicle motor heating, make it very fast starting, and the usefulness of open-air tent and heating of house, also can be used for the heating of drying of Greenhouse Heating and warehouse, tunnel etc.

Its solution is, on the dolly of forming by fuel tank, fan and thermal chimney are housed, be provided with the combustion chamber in the tube, fuel oil is carried ignition generation hot-air after fuel injection nozzle sprays by the combustion pump, then by fan with hot-air from the place of thermal chimney middle fan to need heating, reach the purpose that adds gentle heating.

An embodiment below in conjunction with this utility model of description of drawings.Accompanying drawing 1 is the general partial sectional view of air-heater, and Fig. 2 is the side view of wind blade 13, and Fig. 3 is the spark plug cutaway view.In Fig. 1,9 is fuel tank, and handgrip 7 and dolly of wheel 12 formations are housed on it.By support 11 motor 6 is housed on the fuel tank 9, fan blade 5 and oil pump 8 are housed on the motor 6, fan blade 5 front ends are equipped with guide vane 13, ignition switch 10 and thermal chimney 1 also are housed on the support 11, establish combustion chamber 2 in the thermal chimney 1, fuel injection nozzle 4 is housed the rear end, combustion chamber and ignition spark plug 3(sees Fig. 2).14 is spark plug center pole among Fig. 3, the 15th, and side pole, the 16th, the side pole seat also is connected with combustion chamber 2, and side pole 15 and side pole seat 16 are by being threaded, so can adjust the gap of side pole 15 and center pole 14.Ignition coil is installed on the support 11, a termination side pole 15 of the secondary coil of ignition coil, another termination high-voltage line 19,18th, high-voltage line clamping sleeve.High-voltage line 19 is connected with center pole 14.After the energising, under the effect of ignition coil, center pole 14 produces the high-tension electricity of about 7500V, thereby produce strong spark in center pole 14 and 15 of side poles, when the gap of center pole 14 and side pole 15 transferred to 4 millimeters, two interpolars can directly produce naked light, thereby lighted diesel oil or kerosene.Spark plug 3 is owing to adopted the form of two utmost point consubstantialities, and center pole 14 and side pole 15 relative positions are stable, so reliable operation.

During work, the air outlet of thermal chimney 1 is aimed at the position that needs heating, and behind the connection power supply, motor 6 is started working, oil pump 8 is extracted the diesel oil in the fuel tank 9 or kerosene out and is emitted into the atomizing shape from fuel injection nozzle 4, fan blade 5 with air propeller to guiding blade 13 and enter the combustion chamber.The effect of guide vane is that control enters the air quantity of combustion chamber, and its angle of inclination can make air form spiral shell and execute that shape enters combustion chamber 2 and fogging oil is fully mixed.Guide vane 13 can be designed to varying number and differing tilt angles by the size of institute's calorific requirement.Connect ignition switch 10, through spark plug 3 ignition, the hot-air that the burning back produces is played the purpose of heating service to the heating position through thermal chimney 1 fan by fan blade 5.

Claims (2)

1, a kind of field work air-heater of forming by fuel tank 9, wheel 12, handgrip 7 and support 11, it is characterized in that on support 11, being equipped with motor 6, oil pump 8, fan blade 5, guide vane 13 and thermal chimney 1, be provided with combustion chamber 2 in the thermal chimney 1, fuel injection nozzle 4 and spark plug 3 are housed on the combustion chamber 2.

2, a kind of according to the said air-heater of claim 1, the gap that it is characterized in that said center pole 14 and side pole 15 is 4 millimeters.
