Description
Technical field
This utility model is related to a kind of hand-held hot air tool, more particularly, to a kind of temperature and air quantity is adjustable and automatic time delay
The hand-held hot air tool of shutdown.
Background technology
Hand-held hot air tool includes the various ways such as plastic welding gun, hot air welding gun, is mainly used in plastic thermoforming, moulds
The fields such as material thermal weld, plastics thermal contraction, hot air type drying.Operation principle is using motor rotational band wind symptom leaf, produces blowing；
Blowing, through the resistance wire of heating, takes away heat, forms hot blast, by air duct and tuyere, blows on required work surface.
Earliest hand-held hot air tool, only by the proportion adjustment of simple controllable silicon and potentiometer, to set heat
The temperature value of wind, and air quantity can not adjust.The shortcoming of this equipment is, once air outlet be blocked or air inlet air quantity not
Foot, heat generating core is easy to overheated and burns；And adjust temperature using potentiometer, a general value range can only be set, no
Can determine that actual set temperature, nor determine whether operating temperature is exactly required design temperature；Because air quantity can not be adjusted,
The demand of the working environment of low air quantity can not be met, when working under the long-time condition of high temperature, if power supply is pulled up in quick shutdown
Plug, fan electromotor stall immediately, now the high temperature of heat generating core can rapidly toward plastics gun platform return, temperature may be up to 400 DEG C with
On, not only working of plastics can be softened, or even fusing, the resistance wire Quick Oxidation in heat generating core also can be caused aging, or even blow.
The hand-held hot air tool subsequently coming out, has various improvement.The gear that increased air quantity having, is opened using gear
Close and to realize the size adjustment of air quantity.But due to only with simple IC chip, not adopting intelligentized single-chip microprocessor MCU
Chip, does not have program intelligent decision working condition, so intelligent automatic delay switching-off function cannot be realized, still cannot be real
Ground improves and extends the service life of heat generating core.Some hand-held hot air tools increased temperature sensor, including：Photosensitive electricity
Resistance, thermocouple etc., utilize temperature sensors for realizing the regulation of temperature.But due to only with simple IC chip, not having
Using intelligentized single-chip microprocessor MCU chip, so temperature automatic adjustment function cannot be realized.
By the comparison of IC chip, form the temperature limiting function of reaction type, than the simple proportion expression circuit of initial stage
There is larger lifting.When due to causing temperature anomaly to rise limited by air quantity, extra temperature limiting protection can be played, and drop
The voltage of low heat generating core, to guarantee that heat generating core will not overheated burn.These improvement improve product quality and performances, extend and make
Use the life-span.But in place of there are various problem and shortage：1st, the work temperature setting simply by the potentiometer anglec of rotation
Degree is it is impossible to intuitively inform user desired temperature；2nd, actual work temperature and design temperature, if there is inconsistent, use
Person also cannot learn；3rd, the temperature error between Different Individual, user also cannot overcome；If 4 air outlets block or enter
Air port blocks, and in the case of deficiency in draught, considerably more than design temperature, user also cannot quickly solve event to actual temperature
Barrier, or even heat generating core is overheated leads to burn；If the 5, temperature sensor is covered by debris or other reason leads to signal weak,
So actual work temperature will deviate significantly from setting value, and heat generating core easily burns because of high temperature；6th, Wind Volume is hand-held
Formula hot air tool, if using under the working environment that detaching electronic elements, welding PVC welding rod etc. need low air quantity, cannot
Use well；7th, in the case of hot operation, directly close power failure machine, the lasting high-temperature residual heat of heat generating core is easy to internal electricity
Resistance silk fusing, greatly affects service life.And user, due to due to inertia or custom, does not ensure that each use
All adjust the temperature to cold wind state manually, cooling heat generating core is long-time enough.
In addition, this hand-held hot air tool is in use, producer can in the description Special attention will be given to shutdown when,
Manually temperature adjustment knob need to be adjusted to minimum temperature, using cold front heavy rain heat generating core, then operator is checked with feel frequently
Draught temperature, after judging that temperature reaches the low life-span being not enough to and affecting heat generating core, more manually shuts down.This manual operation is closed
The step of machine, relatively complicated, the work efficiency of impact operator, often ignored by operator.Even if having on operation instructions
Emphasize that this correct shutdown procedures is critically important, but it is practicable to be implemented.
