See that Fig. 3,5,6 electrode switch can be by placing the electrode 37 in the retaining ring 40 on the bowl cover, outer electrode 38, the electrodes 39 of cup at the end of retaining ring not to realize on-off action with being communicated with of water. Wherein electrode 37,39 and magnetic valve 18 are electrically connected to form to above-mentioned maximum amount of water control, electrode 38,39 and relay 43 are electrically connected, constitute least quantity control, promptly when the water yield is less than minimum controlled quentity controlled variable in the cup 22, electrode 38,39 disconnects, relay 43 disconnects, heating 42 stops heating, prevents the cup scaling loss.

The course of work of this hair-dryer is described below in conjunction with Fig. 6.At first, similar to the common electrical blowing when being used for dried blowing, operating circuit is seen the empty frame line part of Fig. 6.During wet blowing, switch b pushes the top to, the low gear heating element heater work of steam superheater 9, the power supply that goes out of rectification makes motor 17 drive reciprocal air pump 13 work thus, air pump is rapidly to air chamber 5 gas transmissions, improving air chamber pressure enters in vaporization separator 12 cups 22 water in the water tank 4 under air chamber 5 air pressure promote, and rapidly water row is formed the moisture film ring of making circular motion with impeller to cup internal perisporium face by the impeller of high speed rotating, during when the water yield that enters in case above minimum controlled quentity controlled variable, no matter which kind of use location moisture film cup of hair-dryer is all with at the bottom of the cup, bowl cover is communicated with and is full of the cup internal perisporium face that has heating also is heating surface.At this moment, water is with electrode 38,39 are communicated with, relay 43 closures that are electrically connected with electrode, make the electrical heating elements 42 connection work of vaporization separator 12, because the heating surface of heating power and water is stable, impeller stirs and has strengthened the heat exchange effect greatly in addition, vaporization separator 12 just produces steam in several seconds, Qi Hua water is not under the impeller centrifugal action, continue to form the moisture film ring along cup internal perisporium face, steam then forms more stable " a vapour post " in the certain diameter scope of the central shaft position of cup 22, the carbonated drink interface is clear to be divided (hair-dryer operating position frequent changes is still like this), the vapour post surrounds bowl cover gland steam exhauster 24 within it, and steam is through gland steam exhauster 24, steam guiding tube 20 enters the pure steam of steam superheater 9 back ejections of preheating.When the vapor (steam) temperature of ejection need improve, push switch b to below, two groups of heating element heaters of steam superheater 9 are all worked, and just can meet the demands.When the water yield that enters vaporization separator 12 reaches the maximum control water yield, be fixed on the impeller blade 44, circle 41 (see figure 7)s of band longitudinal rib drive water around the rotation of retaining ring 40 outer walls, and make water be the rotation attitude to enter and contact with electrode 37 in the retaining ring, this moment electrode 37,39 are connected by water, relay J 2 work through being electrically connected with it force the magnetic valve that is connected on the feed pipe 25 18 that water is blocked, so that the water yield in the cup is less than maximum controlled quentity controlled variable or force the magnetic valve 18 (can be reversal valve) that is connected on the air supply pipe 29 to turn-off main gas circuit, the air chamber of emptying simultaneously, air pressure is descended, thereby reduce output rapidly, reach the purpose of the control water yield.As seen, on the impeller with ribbing circle 41 be fixed in the auxiliary machinery that retaining ring 40 on the bowl cover constitutes maximum amount of water control, when its made that entering water yields in the cup 22 only reaches maximum controlled quentity controlled variable, water just can enter in the retaining ring.Otherwise under the normal operating conditions, water enters cup corresponding in the retaining ring 40 22 interior water yields and is the maximum control water yield.

This hair dryer also can be done, wet blowing mixed use.

Embodiment two

As shown in Figure 8, on existing hair dryer structure, set up and contained vaporization separation superheater, the wet blowing structure of pneumatic water-feed and water quantity controller, wherein vaporization separation superheater is fixed on Blower Housing 32 central shaft positions by fixed mount 11, heating wire 10 is centered around vaporization to be separated around the superheater, and be fixed in the housing 32 by heating wire fixed mount 31, vaporization separates superheater by electrical bar 33, have resistive film on the shell, inner surface is the cylindrical shell 34 of porous heat transfer face, leading vapour intubate 35 constitutes, the described vapour intubate 35 of leading is inserted and secured on the cylindrical shell 34 central axis positions, and electrical bar 33 1 ends insert leads that the other end is fixed on the cylindrical shell 34 in the vapour intubate 35.Wherein, electrical bar 33 just constitutes steam superheater with the ring-type heating space of leading vapour intubate 35 coaxial lines installation formation, electrical bar 33, and the annulus that cylindrical shell 34 constitutes is the vaporization separated space.

Being fixed on casing 36 in the handle 14 with fixture 16 is fixed in cortex elastic membrane 3 in it and separates and become water tank 4 and air chamber 5.Air chamber 5 is connected with air pump 13 through air supply pipe 29, constitutes pneumatic water-feed, and air pump 13 and impeller 7 shared motors 6 interconnect and are fixed in the Blower Housing 32.Above-mentioned water quantity controller is made of the constant pressure valve 26 that is connected on the air supply pipe 29.

When this blower fan work, cylindrical shell 34 and electrical bar 33 begin heating, and pneumatic water-feed starts, and impel air chamber pressure to rise, air chamber expands, water in the water tank is pressed in the cylindrical shell 34 through feed pipe 25, and the water in the cylindrical shell absorbs heat rapidly and vaporizes, and forms vapour pressure in cylindrical shell 34 rapidly, the pressure of this pressure and air chamber 5 will soon be near the constant pressure valve set pressure, form a dynamic equilibrium and settle out, at this moment, because of the pressure differential on the feed pipe 25 realizes stable making that output is corresponding to settle out substantially.Meanwhile the carbonated drink space proportion also obtains corresponding stablely in the cylindrical shell 34, and vapour takes up space and take up space greater than water, reaches output and evaporating capacity dynamic equilibrium substantially, and the water yield that enters cylindrical shell 34 is controlled.In addition, be not enough to produce full boiling that carbonated drink is regardless of during because of the vaporization of the water yields in the cylindrical shell 34 and water arrived lead vapour intubate 35 mouths of pipe, thereby make that entering what lead the vapour intubate all is steam, steam is discharged after superheater is overheated.

When the conversion of hair-dryer operating position, more stable because of the output of pneumatic water-feed, it is also basicly stable to reach the heating surface (area) (HSs that contact with water in the cylindrical shell 34, so the heating vaporization is stable substantially.So steam can be discharged continuously.

Certainly, pneumatic water-feed separates superheater with vaporization fixed-site is not limited only to above-mentioned form, also can do other conversion.Pneumatic water-feed is so long as outwards supply water by air chamber pressure, and its component part is also convertible, as utilizes the low temperature phase change chemical substance to make source of the gas control gas chamber volume to change and realize supplying water.This material places by the separated air chamber of elastic membrane, and the air chamber place adds an attemperating unit, control phase transformation and degree thereof.And for example air pump 13 also can be other types such as rotator type.It is also like this that vaporization separates superheater.

The wet part of blowing that is made of pneumatic water-feed, vaporization separation superheater and water quantity controller is not only applicable to hair dryer in addition, is applicable to other beauty appliance yet.
