Deflection plate 54 is by terminal 70 terminations of blunt shape, thereby around its air-flow generation turbulent flow, therefore further strengthened gas and mixed and the temperature stabilization effect.

As previously mentioned, hair-dryer comprises gas burner and gas reservoir and fan generally.In addition, describe in detail, also be provided with to power-producing control circuit of fan and battery as following.First deflection plate surrounds burner, prevents the air-flow cool burner.Second deflection plate makes the gas turns of coming out from burner, thereby mixes with air-flow around burner.

Fig. 5 to 12 shows the various product structures of hair-dryer of the present invention in schematic form, but for clarity sake, does not demonstrate housing and control assembly among these figure.Each figure has demonstrated and has been labeled as 300 wireless hair-dryer usually, and it comprises fan 302, burner 304, terminal nozzle 306, battery pack 308 and gas container tank (gas canister) 310.Fan 302, burner 304 and nozzle 306 have limited a shared axis 312, and burner 304 is between fan 302 and the nozzle 306, but being contemplated to remaining part can have different structures.In each case, design all will be avoided being blocked by the air-flow of fan, to keep the needed power minimum of drive fan.

With reference to Fig. 5, the battery pack that has larger capacity batteries is hung in bottom, and parallel with axle 312, is 2 * 2 structures in fan 302 the place aheads.Gas container jar 310 is vertically given prominence to below axle 312, and places between fan 302 and the battery pack 308, and for strengthening security, it can be accommodated among the abundant handle away from burner.In Fig. 6, the battery pack 308 and the gas container tank 310 that have larger capacity batteries are arranged with respect to burner reverse, with the raising capacity.In Fig. 7 a and Fig. 7 b, gas container jar 310 is provided with along axle 312, but is positioned at the rear portion of fan 302, and has more short and thick structure.

With reference to Fig. 8 a and Fig. 8 b, its structure is to shown in Figure 6 similar, but gas container jar 310 is positioned at the top rather than the below of axle 312.

The structure of Fig. 9 a and Fig. 9 b is similar to Fig. 6's, but the profile of gas container jar 310 has slight variation, thereby forms the tapered taper from the bottom.

With reference to Figure 10 a and Figure 10 b, except the direction of fan was changed, its structure was to shown in Figure 7 similar.Particularly, fan is positioned at axle 312 belows and square with the axis, thereby air can be promoted to axle.As a result of, the guide plate that need to be fit to with air deflection to burner.

Except gas container jar 310 housings more elongated, fan 302 were more elongated, the structure of Figure 11 a and Figure 11 b is similar to Fig. 7 also.In addition, battery pack 308 is arranged to 4 * 1 structure.

With reference to Figure 12 a and Figure 12 b, all parts are all arranged in a line with axle 312 at last.Gas compartment extends along axle, and is positioned at the rear portion of fan 302, and battery is around the peripheral distribution of gas compartment.In illustrated embodiment, battery is installed in the groove of being located at the gas compartment outer wall with 90 ° interval.

As for the more detailed aspect of the present invention, control and safety circuit can be controlled speed, burning degree, the burner igniting of motor, and provide safety shutdown under various fault modes.Since controller and burner can be physically away from, so less to the needs of pure machinery control and security feature.Owing to can use power supply (being used for motor), the portion gas control system preferably is subjected to that electricity starts and/or is responsive to electricity at least.This can provide the most multiple control method, and from the viewpoint of exploitation, this has is the difficult and dangerous of minimum, and it is about the same with common wired hair-dryer to make control get up.

With reference to the calcspar 399 of control among Fig. 3 and safety circuit, 400 pairs of hair-dryers of rechargeable battery pack are supplied all electric power.Positive pole power supply from battery can be switched by mechanical on/off switch 402.When off (closing) position, not can be used to gas shut-off valve 404 power supplies to (spring returns) operated by solenoid of closing usually, this valve comprises reservoir valve.

When switch 402 is positioned on (unlatching) position, link to each other with blade type AFS 406 from the charged connecting line of battery.This switch is made up of plastics molded blade and micro switch.Open and air-flow on minimum of a value the time when fan, switch 406 cuts out, and battery supply 400 is connected with overtemperature thermal switch 408.In selectable embodiment, may save fluid flow switch 406, and rely on overtemperature switch 408 purely and detect the decline of air-flow or lack.

The overtemperature thermal switch 408 of any suitable type is placed near burner and sentences overheated (the overfire level, limited air-flow or fan/motor fault) that detection is produced by any reason.If switch 408 is opened owing to overheated, power will disconnect with magnetic valve 404 so, thereby close gas source 414.The magnetic hysteresis effect of switch 408 should be such, has served as under the situation that cold temperature switch 416 opened, and it will no longer be closed, and till temperature is in normal range (NR), so just can prevent the possibility that gas trap 404 is opened once more when component unit cools off.

Ensuing parts are supercooling temperature thermal switch 416 and switch (override switch) 418 that surmounts in parallel with it in the safety circuit 399.Except when when surmounting switch 418 and being placed ignition location by the user, (any suitable type) supercooling temperature thermal switch 416 will be opened, if the temperature of burner below predetermined value (this show burner 410 not or do not lighted).If gas burner 410 is not lighted, it can remove the power supply to gas control valve 404, thereby disconnects the gas supply.

Overheated and mistake cold switch all comprises the condition sensor, and they are located on the deflection plate shown in Figure 1 56.

Be initial point burner 410, surmount switch 418 and be moved to ignition location that supercooling temperature switch 416 can instantaneously be walked around in this position, thereby provide power to open gas trap 404.Surmounting switch 418 also provides power to light gas to burner firing circuit 420.Because power supply can be electrically connected by safety circuit with electronic igniting circuit, therefore impossible operating point ignition circuit is unless switch 418 is in ignition location.

In case light gas, cross cold switch after several seconds and will close, and power supply 400 will keep being connected with magnetic valve 404 after surmounting the switch relieving.The observation circuit 422 that light is isolated determines whether supercooling temperature switches 416 have closed to show that by lighting LED burner lights.422 pairs of safety circuits of observation circuit are influence not, be the indicator of lighting as gas 424 fully for the user, and it also can decontrol the switch 418 of lighting a fire/surmount.The fault of observation circuit 422 is meant to show mistakenly whether burner is lighted, and it is to the not influence of safety shutdown of gas supply.

Use for example on/off cycle pulsewidth modulation of valve to regulate under the situation of hot degree in gas shut-off valve 404, the light isolation signals is switched the ON/OFF that arrives the power of magnetic valve by isolator 426 by isolator 426 with electronics.When other electrical connection safety component indication had failure condition, the fault of electronic circuit will not be opened control valve.

Using manual modulation valve 428 to realize can omitting optically coupled isolation circuit under the situation of gas regulation, gas solenoid valve 404 directly is connected with the link that surmounts switch 418 with supercooling temperature switch 416.

The control of motor is not crucial for the security of hair-dryer, but therefore electric control, and this is can be detected by the overheat awitch that is electrically connected (if desired, also having AFS) because cause overheated fault.Yet safety-critical parts such as magnetic valve 404 use electromechanical component to connect.In addition, HT source of supply 430 to igniter 420 be that each isolated part 432,426 by any suitable type in the electronic control circuit 434 carries out electricity light and isolates to being connected of magnetic valve.

According to this configuration, the safety-critical circuit can not be subjected to the infringement of electronic unit fault.This point can guarantee that it can prevent to provide power or incorrect activation member to any monitoring of the control circuit of electronic unit or control circuit to safety circuit by making with the light isolated part.The fault of electronic control circuit can stop the operation of hair-dryer, but always is in the failure safe mode.

Can not the ignition combustion device (or subsequently because the burner that control or failure cause cause extinguish), overheated condition (because fan/motor fault, airflow obstruction etc.) or air-flow be lower than under the situation of floor level, safety circuit is cut off the gas supply.

Regulate about Electric Machine Control and electronic gas, have two embodiments to can be used to realize gas regulation (so that different heat settings to be provided).A kind of scheme is to use manual modulation valve 428 so that variable thermal control to be provided, and another kind of scheme is that ON/OFF cycle of adjustments of gas shut off valve is with the control mean air flow.

The electronically controlled advantage of magnetic valve is to have reduced mechanical part (though having increased Electronic Control) and freer on the installation site of controller and type.

Electronic control circuit (ECC) 434 is preferably printed circuit board (PCB), except possible magnetic valve PWM (pulsewidth modulation) control piece, this printed circuit board (PCB) also is provided with PWM speed control piece, the firing circuit when needing 430 (referring to part 3.11) of fan electromotor, battery detection circuit and low battery demonstration LED 436, burner are lighted monitoring and are shown LED 424, " terminal box " that the mounting platform of the mounting platform of on/off/ ignition switch, burner gauge tap 438 and motor control switch 440 and the mounting platform of gas solenoid valve 404 are connected with cable.

But Fig. 4 illustrates a kind of possible structure 499 of the gauge tap and the indicator of hair-dryer of the present invention.

An on/off (ON/OFF) slide switch 500 has been controlled all supplies of electric power from the battery pack to the hair-dryer.When switch was in " closing (off) " position, institute is dynamic to be eliminated from electronic unit, fan electromotor and solenoid gas shut off valve, thereby guarantees gas source is closed.On/off slide switch 500 depressions are entered, and it must be compressed into before it may being moved from the off position.This can make the possibility minimum of accidental operation.

Switch is moved on to " opening (on) " position 504 and can provide power to electronic unit and circuit for controlling motor.Fan will be to turn round by " fan speed " gauge tap 512 selected speed, and it can be to provide 2 positions of two kinds of fan speeds or the switch that multiple speed is provided with.Gas is still and closes when this state.

On/off slide switch 500 has the 3rd momentary spring loaded position 506.This is " igniting " position, and the user must hold switch and give me a little the combustion gas body.Switch is moved on to this position to be opened gas trap and opens HT spark lighter 430 (Fig. 3).In case burner is lighted, temperature sensor will detect this point so, and the LED lamp 508 luminous gases that show are lighted, but and user's trip switch 500 to turn back to " on " position 504.If user's trip switch before gas is lighted, the gas supply will be cut off so, and hair-dryer will continue to blow out cold air.Switch must be moved to " igniting " position 506 once more to open gas supply and starting ignition circuit.

By the hot degree of switch (or hand regulator) 510 controls, it can provide two kinds of hot degree or multiple heat is provided with.

After the use, the user moves to slide switch " off " position 502.This will make fan stop, and close the gas supply valve.Refire the gas supply, the user must the relight process.

" cold jet " option also may relate to be extinguished burner and refires.Also can carry out the unit switched to " off ", switch be moved to " on " and the cold air operation of not lighting gas then.

About the igniting of burner, preferred embodiment be spark ignition systems 430 discussed above, it can repeat to produce spark and be lighted or till the user unclamps button ignition switch up to gas.This electronic system can be used for conventional power supply power blower by similar mode.

More cheap selection is the simple and mechanical piezo-electric ignition system of any suitable type.In case when the user moves to ignition location with on/off/ ignition switch 500, piezoelectricity will be triggered.Its shortcoming is that the user need repeat this process if burner can not be lighted, if burner is sightless, this will be unconspicuous in tens seconds.

Safer and related aspect comprises the position of spark point, can further make the possibility that gaseous product is lighted owing to the siloxanes that forms on spark point (silicone) reach minimum to the selection of this position.

In addition, enter product, be provided with filter or grid at the air intake place for preventing hair.This can prevent that hair is sucked into because of the reason of fan and twines, and other chip can be stayed the outside.

In addition, for the fragment (for example pubescence, hair etc.) that prevents the inspiration hair-dryer is lighted by gas burner, and go out as comburant or very hot particle jetting, at first the air intake filter will prevent that most of particles are sucked into hair-dryer, secondly the indrawn minimizing possibility of any particle that will contact with flame or very hot surface by deisgn product.Particularly, gas burner works by catalyst, under the temperature of about 500-800 ℃ (rather than 1300 ℃), is fireless burning basically therefore.In addition, thus these thermocatalytic surfaces prevent inhaled air keeps burning.Like this, the particle that sucks by product just can not be exposed under the high temperature that may work the mischief.

In addition, can reasonably be used for the product (as gel and hairspray) of hair-dryer less than not shown danger because of various characteristics.

For example, air-flow can be controlled by product, thereby aerosol etc. reduce with the possibility that contacts on surface, therefore have enough focuses to fire them, and spark ignition sources is suitably placed, and the operating temperature of catalytic burner is lowered, and the burning of safety takes place in the hair-dryer.

Therefore, the present invention described here only is a simple application, and similar to existing wired hair-dryer in the use.It provides that gas under the situation about extinguishing of burner ignition failure or any reason is closed, two-stage (or more) thermal outputs and fan speed, gas igniting, the air-flow that reduces detects and gas is closed, overheated detection and gas is closed, cross cold detection and gas is closed (it can be used for detecting ignition failure), the low indication of battery and combustion indicator.

Be appreciated that when suitable do not break away under the present invention's design capable of being combined or exchange the feature and the parts of various embodiments.If it is general or the stock in hand product supplied for described each parts, should be known for the reader who is familiar with so, therefore be not elaborated.
