Enter in upper chamber 13, hot blast out disperses again out of intercommunicating pore 111, and then hot blast enters branch by outlet pipe 5
In road outlet passageway 711, finally discharged out of main outlet passageway 721.
The temperature value of detection is passed to controller by air outlet temperature monitoring sensor and temperaturecontrol sensor respectively, control
Realized in device processed and be provided with temperature value, when the temperature value that the two Sensor monitorings are arrived is within the scope of the temperature in controller,
Then the hot blast temperature of gas outlet reaches the temperature value specified.
If a sensor senses that temperature value it is relatively low when, controller control heat gun in hot-air system heated,
If a sensor senses that temperature value it is higher when, controller control heat gun in hot-air system stop heating.
High-temperature hot-air is by can be by the steel wire lump inside housing 1 itself and upper chamber 13, lower chambers 14 during the invention
Absorb a part of heat；When heat gun is not in warm-up mode, the hot blast of heat gun blowout can then be less than the temperature of setting, now
Because of heat exchange, the temperature entrained by housing 1 itself and steel wire lump can be taken and be compensated out of the temperature difference of hot blast by low temperature hot blast, so that
The temperature of hot blast can be controlled in the margin of tolerance of demand temperature.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modifications, equivalent substitutions and improvements made etc. should be included in the invention
Protection domain within.
