From known another the such curling iron of JP 2-25902.

Such problem at present common curling iron, often occurs, promptly the user can not or can not apply constant compression force at least consistently when using curling iron, and constant compression force can produce best hairdressing effect usually.In curling iron, the pressure on the hair is relevant with user's manipulation, and wherein too high pressure can cause hair to damage, and too small pressure can cause unfavorable hairdressing effect.

Therefore, the present invention is devoted to address this problem, and for such curling iron, proposes better a kind of or alternative embodiment at least, and it especially simplifies the application of curling iron for unskilled people.

Said problem is able to solve through the theme of independent claims 1 by the present invention.Favourable embodiment is the theme of dependent claims.

The present invention is based on common design: known curling iron own has two arms that support each other swingably; It so constitutes: the pressure independent ground with the user when using curling iron is applied to constant and predefined pressure on the hair, and can realize the hairdressing effect of the best thus.At this, on the arm of supporting the plate of haircuting is set respectively usually each other swingably at two, wherein at least one can be heated.In the said plate of haircuting at least one but preferred two support through spring assembly spring ground; Wherein spring assembly has constant spring indicatrix in predefined scope; Thereby when using curling iron usually, can preferred constant compression force be applied on the hair, promptly irrelevant with the actual applied pressure of user.Therefore by by curling iron of the present invention,, and can obtain best hairdressing effect even concerning unskilled people, also can correctly use curling iron.

In a kind of favourable improvement project of the present invention, spring assembly is a pretension.In the plate load beginning of haircuting, the rising that the spring indicatrix exists at first usually is the required pressure of the best hairdressing effect of realization thereby provide apace thus.In this case, the scope that has constant elastic force just begins to make at load and directly begins.Certainly, spring assembly can have a plurality of single springs at this, and said spring all has the spring indicatrix of sign.

Suitable is, display unit is set, as long as the plate of haircuting of at least one spring is load, this display unit just produces acoustics and/or optical signalling.Thus, the user that can accuse immediately, curling iron is in service.In order to improve, display unit can have light-emitting device, and this light-emitting device can produce following optical signal: as long as curling iron is opened, then produce blue light; As long as curling iron is closed and both be not lower than and also do not exceed predefined scope, then produce green glow; As long as exceeded predefined scope, then produce ruddiness.Therefore, the user confirms that when green glow he will be applied on the hair for realizing the corresponding pressure of best hairdressing effect, and on the contrary, the user can recognize when ruddiness immediately, is applied to the hypertonia on the curling iron by him, and this may cause damaging hair.Additional or be alternative in this; Display unit can have audio unit; Need only the curling iron closure and both be not lower than and also do not exceed predefined scope; Then this audio unit just can produce acoustic signal, as long as and/or exceeded predefined scope, then this audio unit just can produce other and/or alternative acoustic signal.This audio unit is being favourable under the following situation particularly: do not have direct vision to contact with it when using curling iron on the hair of user at oneself, and therefore can not see the signal that is for example sent by light-emitting device.This audio unit for example can be with low cost and small-sized electrical loudspeaker, and it needs to produce the understandable signal of user that is used for curling iron.

Other important feature and advantage of the present invention are by drawing according to accompanying drawing in dependent claims, accompanying drawing and the affiliated description of drawings.

Obviously, the aforesaid and characteristic that also will set forth of back can be not only in the combination that provides respectively, and in other combination or use individually, and do not deviate from category of the present invention.

Set forth the preferred embodiments of the present invention in the shown in the drawings and explanation below in detail, it is identical or similarly or the identical parts of function that wherein identical Reference numeral is represented.

It is schematically illustrated respectively at this,

Fig. 1 shows the cutaway view by curling iron of the present invention;

Fig. 2 shows the possible spring indicatrix of supporting structure of spring or spring of the plate of haircuting of curling iron;

Fig. 3 a shows the possible embodiment of sensor device when curling iron is opened;

Fig. 3 b shows the view the same with Fig. 3 a, yet curling iron is closed.

According to Fig. 1, be commonly called heater of hair straightener by curling iron 1 of the present invention, and have two arms 2 and 3 that support each other swingably, wherein on two arms 2,3, be respectively arranged with the plate 4,5 of haircuting.But at least one in the said plate 4,5 of haircuting is in this especially electrical heating.Certainly it is also conceivable that at this that the haircut plate 4 and/or the plate 5 of haircuting form the integrated part of each arm 2,3, rather than as in the example depicted in fig. 1, place.Relatively gentlier and simultaneously guarantee correct use in order to guarantee curling iron 1; Haircut in the plate 4,5 at least one but preferred two support through spring assembly 6 spring ground; Wherein spring assembly 6 in predefined scope D (with reference to Fig. 2) has constant spring indicatrix, thereby when using curling iron 1, can preferred constant compression force be applied on the hair 8.The single spring 13 of spring assembly 6 or spring assembly 6 is at this pretension, thus travel range (Wegbereich) S ₁In Fig. 2, be preferably zero, and begin just directly predefined elastic force F to be provided in plate 4,5 load of haircuting, elastic force F at first rises usually in the trip scope.

In addition, also display unit 7 can be set, it produces acoustics and/or optical signalling, as long as the plate 4,5 of haircuting of at least one spring is by load.Display unit 7 can have light-emitting device 9 at this, and when curling iron 1 closure, produces optical signal at least.What also can consider is that display unit 7 can produce following optical signal: as long as curling iron 1 is opened, then produce blue light; Need only curling iron 1 closure and do not exceed predefined scope D, then produce green glow; As long as exceeded predefined scope D, then produce ruddiness.For the correct use of curling iron 1 importantly; The pressure F that is applied on the hair 8 is not too small big only; Because otherwise or can only realize hairdressing effect unsatisfactory, the overload ground that perhaps is used in hair 8 rises, and this may cause damaging hair.

Optionally at this be, display unit 7 can produce acoustic signal according to pressure F, and this acoustic signal for example sends through the electrical loudspeaker that does not mark in detail.Because when oneself using by curling iron 1 of the present invention, can not always guarantee: the user can see the optical signalling that is produced by light-emitting device 9, is advantageous particularly so produce acoustic signal.

Show switch 10 according to Fig. 3, this switch is handled corresponding to the closing motion of curling iron 1.Show the switch 10 when curling iron 1 is opened at this according to Fig. 3 a, its middle press pin 11 does not contact with pressing plate 12.Show the curling iron 1 that is in closure state according to Fig. 3 b, wherein show, pressing plate 12 is pressed into the pad 11 of switch 10 in this state.Additionally, block 14 (referring to Fig. 3) can be set also, this block defines the closing motion of curling iron 1.

Therefore by by curling iron 1 of the present invention, both made for unskilled user and also can correctly use curling iron simply, and therefore reduced the danger of unsatisfied hairdressing effect equally, like hair 8 by the danger of too high pressure F damage.The proper operation of curling iron 1 especially can be additionally simplified in the generation of acoustic signal, and what wherein can consider is that this acoustic signal is designed to continue sound, as long as the pressure F that is applied on the hair 8 is arranged in predefined pressure limit D.At this, this scope D so sets, and makes in this scope, both to have reached best hairdressing effect, also can get rid of the danger that hair 8 sustains damage reliably.
