Description

 Hair care device with functional head

The present invention relates to a hair care appliance having a handle, a functional head which can be connected to the handle, which has a hair processing device, in particular a bristle and / or tine field, and an ion discharge device for dispensing ions onto the hair, which has at least one ion outlet.

Recently, hair care appliances, especially hairbrushes, have come to be known, which in addition to their primary function, i. In the case of a hairbrush combing, brushing and shaping the hair, as an additional application ions bring out. Such ions are usually molecules charged with negative electrons. With the help of such an ion application, the hair and hair care can be improved, in particular, a static charging of the hair and a corresponding projection of the hair can be avoided.

From US 2005/284495 a hair brush or a hair dryer with integrated brush attachment is known, which has on an away from the bristle field back of the device and on the bristle field carrying front of the device each having an ion outlet, the ions leak in the direction of the function head.

In such hair care devices with ion application, the ions are on the one hand, of course, deliberately applied to the hair, on the other hand should not be punctual, but a uniformly distributed as possible application of the hair done. The lonenaustrag is not only hampered by direct mechanical obstacles, such as located before the lonenauslass hairs or lying in the user's hand, but also by electrostatic opposing fields of strongly negatively charged components, which so to speak, prevent the negatively charged ions, or Components with high positive charges, which have an attractive field effect on the ions can go out. Charges of this type can, for example, be generated on the bristle field itself when it is combed through the hair. Even in the area of the ion outlet, electrostatic fields can form on the device housing, which can hinder the escape of ions.

Another aspect to be improved in previously known hair care devices of the type mentioned is the safety of use, which can be adversely affected by the aforementioned heavy charges on the device.

BESTATIGUNGSKOPIE Proceeding from this, the present invention has the object to provide an improved hair care device of the type mentioned, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner. In particular, a simple, efficient lonenaustrag on the hair should be achieved with simple means, but without affecting the safety of use of the device.

According to the invention this object is achieved by a hair care device according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

It is therefore proposed to eliminate an electrostatic charge and opposing fields at least on the parts of the hair care device by means of suitable countermeasures which stand in the way of the ion discharge onto the hair or which can impair the release of ions. Without being adversely affected by such electrostatic opposing fields, uniformly distributed but nonetheless targeted and efficient ionization of the hair can be achieved with only a simple formation of the ion applicator, which in a simple embodiment of the invention can manage with only a single ion outlet. According to the invention, the hair care device is characterized in that the functional head and / or a housing part in the vicinity of the ion outlet at least a first ground surface for removal / limitation of electronic charges and said device back, preferably on a component inside, is provided with at least a second ground plane , This second ground plane may also be in the vicinity of the ion outlet, but need not.

The grounding surface, that is to say in each case both the first grounding surface and the second and further grounding surfaces, can be designed as desired. It may have a flat or punctiform contact area, via which a removal / limitation of electronic charges takes place. It may further comprise a contact plate which is connected to another surface, for example an inner surface or outer surface of a plastic component, for example by gluing. The contact surface can be made rigid or flexible. Further, the ground surface may comprise an electrically contacted screw which is screwed into a screw dome in the plastic part.

A ground plane shall be considered herein to be disposed "in the vicinity" of another, if it can act on the other device, that is, to dissipate / confine electronic charges from that other device, the device being directly contacted by the ground plane or even indirectly, even in the case of indirect Contacting the distance to the component should not be more than 1 or 5 or 10 millimeters. The distance may depend on the electrical conductivity of the component or components to be bridged.

Furthermore, the functional head and / or a housing part in the vicinity of the ion outlet may have at least one further grounding surface for discharging / limiting electrostatic charges ("third grounding surface") Such a grounding surface on the functional head and / or on a housing part surrounding the ion outlet prevents or limits excessive charge and, accordingly, electrostatic fields in the region of the functional head and in the region of the ion outlet, which could hinder the lonenaustrag on the hair, in particular can be present both on the function head and on the housing part in the vicinity of the ion outlet such ground surfaces.

The grounding surface can basically be designed differently. In particular, the grounding surface may be formed in the form of a metal surface, which is applied to a non-conductive, preferably made of plastic body or housing part of the functional head and / or the ion outlet. The body of the functional part or the ion outlet per se can therefore continue to be formed as a plastic injection-molded part or plastic part manufactured in another way. The ground surface in the form of a metal surface, which can advantageously be arranged on an outer side of said body parts and form their outer surface, thereby not only prevents the fields from affecting the lonenaustrag, but also increases the reliability of the hair care device.

As an alternative or in addition to a grounding surface on the outside of a body part, in an advantageous embodiment of the invention, a grounding surface can also be provided on an inner surface of a body part. The arrangement on the inside or outside can be different depending on the component. On the other hand, while the grounding surface on the said functional head and / or on an outlet housing enclosing the ion outlet may be provided on an outer surface of the corresponding body part, it brings about particular advantages, on a further body part in the vicinity of the ion outlet, in particular in an exit direction behind the outlet body part, over which the ion cloud spreads, to provide a grounding surface or device on the inner surface of the corresponding body part. With regard to the arrangement of the ground surfaces, different embodiments may be advantageous. On the functional head, an advantageous arrangement may be that the grounding surface is connected to the hair treatment device, in particular the bristle and / or tine field. For example, the grounding surface may form, as it were, the bed which carries the bristles or prongs of the bristle field or the possibly also differently designed processing tool of the hair processing device. Alternatively, or in addition to the aforementioned bristle and / or tine field, the hair processing device may, for example, also have a care surface made of a suitable material, such as ceramic, for hair care. Alternatively or additionally, a heating surface with a suitable shape, in particular a smooth, concave and / or convexly rounded working surface, be provided.

Various configurations may also be advantageous with regard to the arrangement of the grounding surface at the ion outlet ("first grounding surface") and in the vicinity thereof According to an advantageous development of the invention, the ion outlet comprises a preferably separate housing component which forms a box-shaped and / or box-shaped high-voltage element emitting the ions The aforementioned grounding surface is advantageously provided on one of the non-mouth sides of said housing module. The grounding surface can be arranged on a side face of the outlet housing which adjoins the mouth side and which surrounds the abovementioned, preferably mandrel, pin or tip-shaped high-voltage element Alternatively or additionally, a grounding surface may also be provided on a rear outlet housing surface, which is opposite to the mouth side.

As an alternative or in addition to such a grounding surface on the outlet housing, a housing component adjacent to the ion outlet and / or a housing surface arranged in the vicinity of the ion outlet can also be provided with a ground ("second grounding surface") In the aforementioned manner, this housing component may advantageously consist of a non-conductive material and may be provided with a grounding surface applied thereon The electrical grounding of the housing component in the vicinity of the ion outlet can thereby be simplest Embodiment via an electrically contacted screw carried out in a NEN screw in the plastic part is screwed. Alternatively or additionally, the electrical grounding can take place via a contact pressure of a metal electrode, which forms a grounding surface of the aforementioned type. Said housing component or said housing components can be earthed via a contact to the ground potential of the voltage circuit of the device, whereby an electrostatic charge is not impossible, but is sufficiently limited to keep the electric opposing fields resulting from the charging so small that they do not hinder the propagation of ions from the ion outlet.

The electrical grounding of the housing component, over which the ion cloud propagates, advantageously does not occur in the field of view of the ion cloud, but rather on a housing component side facing away from the ion outlet, in particular an inner surface of the housing component.

According to an advantageous development of the invention and in particular of the second grounding surface, the device housing may be provided in an area over which the ion cloud emerging from the ion outlet and / or in the vicinity of the ion outlet with a lonenleit- or ion control device. In this case, control of the ions can be achieved in an advantageous manner by providing a plurality of separate housing components in the vicinity of the ion outlet, at least one of which is grounded and at least one further ungrounded. While the ungrounded housing part can charge electrically and thereby deflect the ions, the ions can propagate unhindered over the grounded housing components, so that by a corresponding pattern of grounded and ungrounded housing components, the propagation of the exiting ions can be controlled accordingly.

Depending on the application, such an ion guide can be designed differently to produce different propagation patterns. In a preferred embodiment of the invention may be provided in the vicinity of the ion outlet a symmetrical to the device longitudinal plane symmetrical pattern of grounded and ungrounded housing components, so that a total symmetrical ion propagation is achieved. Alternatively, however, a deviating from the symmetry with respect to the longitudinal center plane configuration can be made, for example, to create a targeted device for right-handed or a device for left-handers. Alternatively, or in addition to the aforementioned training, the grounding surface to connect directly to the hair processing device, the grounding surface on the functional head ("third grounding surface"), the hair treatment device also circumferentially at least partially, preferably annularly surrounded and / or arranged directly adjacent to the hair treatment device For example, the hair processing device itself, for example the bristle and / or tine field, or the housing body of the functional head itself, may be made of non-conductive material The grounding surface may advantageously be provided at the edge next to the hair processing device in the hair processing device carrying the fun be arranged ktionskopf.

In a development of the invention, the housing potential is also electrically contacted with the body of the user. In a development of the invention, the handle of the hair care appliance can have an electrically conductive contact surface for discharging positive charges to the respective user of the hair care appliance. This protects the user from charging. Namely, the release of negative ions can negatively charge the user. On the other hand, positive contact charges can be transmitted to the user through the contact surface on the handle, whereby the charging effect is compensated by the negative ions. This is particularly advantageous in the case of an embodiment of the hair care device without a mains connection, in particular as a battery and / or cordless device. In such a non-power supply, the generation of negative ions usually causes an equivalent amount of positive charge on the device, since the device as a battery or cordless device, the reference potential is missing. Due to this positive charge on the device, a negative charging of the user can be compensated for via the aforementioned electrically effective contact surface on the handle.

Due to the largely pollution-free ion delivery to the hair, which is achieved by the ground surfaces and the thereby eliminated or clipped charge fields on the device, a particularly simple design of the ion discharge device can be achieved, in particular with regard to ion outlet. In a further development of the invention, it can be provided in particular that the ion delivery takes place exclusively on the rear side of the device, which faces away from the hair processing device providing the primary function of the hair care device. Surprisingly, this makes it possible to produce ions that are distributed evenly and nevertheless directed specifically to the hair. be enough. So far, it has usually been attempted to apply at least some of the ions on the front of the device in the area of the hair processing tool, so to speak to introduce the ions directly into the area to be cared for, since it is assumed that ions applied to the back of the device are more or less at the target, ie the hair to be cared for. In particular, in connection with the above-described ground surfaces and the elimination or limitation of disturbing charge fields can be achieved by a lonenaustrag on the back of the device a particularly evenly distributed, yet almost complete application of the ions on the hair, as the hair usually one - of the discharged ions to be compensated - positive charge that attracts the ions. This effect is sufficient if no stronger interference fields on the hair care device are present, which would hinder the lonenaustrag. By the arrangement of the ion outlet or all ion outlets on the back of the device, the release of ions takes place without mechanical hindrances by a user's hand or hair strands located in front of the ion outlet.

Basically, a single ion outlet may be sufficient. Optionally, several ion outlets can be arranged on the back of the device. In both cases, the arrangement is advantageously made symmetrical to the longitudinal center plane of the hair care device. The at least one ion outlet or the plurality of ion outlets is preferably such that a main exit direction of the ions or the sum of the main exit directions of the ions is directed in the plane of the rear side surface or over the surface of the rear side symmetrically to the longitudinal center plane. The main exit direction of the ion outlet is advantageously substantially - roughly speaking - aligned parallel to the rear side surface, so that the ions emerge substantially parallel to the rear side of the device. Alternatively or additionally, it may be provided a slightly acute angle (upwards) splayed ion delivery. In this case, the ion outlet at an angle of preferably 0 ° to 45 °, preferably 0 ° to 30 °, be inclined to the surface of the back.

In order to achieve a uniform distribution of ions on the hair, the at least one ion outlet is arranged on the edge of the device rear surface, which is opposite the hair processing device, so that an ion cloud forms over the rear side of the functional head.

In the arrangement of only a single ion outlet this is advantageously arranged in the longitudinal center plane itself. When two ion outlets are placed on the straight line back side they can be spaced from each other at the same height to each other and preferably inclined slightly inclined to the median plane of the longitudinal center plane. Alternatively, if two ion outlets are arranged on the rear of the device, an opposing arrangement can be provided such that both ion outlets are arranged on opposite edges of the rear functional head surface and directed towards each other, so that they allow the ions to exit one another as it were.

The hair processing device can be firmly connected to the functional head and can also be firmly integrated into the functional head. Alternatively, the hair treatment device can advantageously be exchangeably mounted on the functional head, so that a functional head can be connected and used with different hair processing device. In addition to a bristle or tine field also other hair processing device in question, such as: a heat treatment device, a heatable hair straightener, a hot air device, such as a hair dryer or a hot air brush. Such various hair processing devices typically require various ways of handing and gripping the device, so it is advantageous to offer electrically conductive surfaces in the manner disclosed. In addition, the ion current should be delivered so that it is well compatible in both its strength and its geometric distribution with a variety of functional heads.

The hair care device 1 illustrated in FIGS. 1 and 2 comprises a device base body 2 which has a handle 3 and has electronic devices to be described in its interior or on its outer shell. Said handle 3 carries a functional head 4, which carries a bristle field 6 as a hair processing device 5 on the front of the device 7. However, it is understood that other hair processing tools, such as heating elements or hair styling elements or possibly also a fan output, may be provided when the hair care device is designed as a hair styling device and / or hair dryer. The mentioned hair processing tools can also be combined if necessary.

The said hair processing device 5 can be firmly integrated into the functional head 4. Alternatively, the hair processing device 5 can advantageously be exchangeable be mounted to the functional head 4, so that a functional head 4 with different hair processing devices 5 can be equipped and used.

Advantageously, the hair care appliance 1 can have a modular construction with a plurality of components that can be connected, wherein, in particular, the entire functional head 4 and / or the hair processing apparatus 5 can be formed separately from the appliance body 2 in the aforementioned manner. In this case, between the various components advantageously positively acting connection means may be provided, for example in the form of locking tongues and pockets that allow a tool-free removal and replacement of the blocks.

As shown in FIGS. 1 and 2, an ion discharge device 9, which comprises an ion emitter disposed in the interior of the device base body 2 and / or a high-voltage element 12 arranged in the ion outlet 11, is furthermore provided on the device base body 2 on the device rear side 8 facing away from the hair processing device 5 which may comprise ions. Said high-voltage element 12 can be arranged in a box-like or jacket-like outlet housing 13, the wall of which has an outlet opening 17 on an outlet side 14, through which the emitted ions can escape.

In the illustrated embodiment, the ion outlet 11 is nozzle-shaped or diffuser-like and causes a directed ion outlet, cf. FIG. 2. Advantageously, the ion outlet 11 is arranged on the rear side of the device 8, which is opposite to the bristle field 6 or faces away from it and, as it were, forms the back of the hairbrush. Advantageously, in this case, the ion outlet 11 is arranged in the longitudinal center plane 18, which forms the plane of the drawing of Figure 2, wherein advantageously the ion outlet 11 with its main exit direction 19 slightly inclined at an acute angle to the rear surface of the device and directed away from this, see. Figure 2, wherein the inclination angle is advantageously between 0 ° and 45 ° and in the illustrated embodiment may advantageously be approximately between 20 ° and 30 °. As shown in FIGS. 1 and 2, the ion outlet 11 is arranged at the edge of the rear side surface of the functional head, which is opposite to the bristle field 6, so that the ions emerging from the ion outlet 11 form an ion cloud over the rear side of the functional head 4. In particular, the ion outlet 11, as shown in FIG. 1, can be arranged approximately - roughly speaking - in the transition region between the handle 3 and the functional head 4. In the interior of the device main body 2, a not specifically shown power supply unit is housed, which may preferably be in the form of a battery or rechargeable battery device. Advantageously, the hair care device 1 is designed energy self-sufficient, ie it has no permanent power supply that would provide power from the outlet. Of course, a power cord can be plugged in to charge the batteries inside the device body 2. Via the said power supply unit, the lone-nausbringvorrichtung 9 is fed to effect the ion generation.

As FIG. 2 shows, the hair care appliance 1 is advantageously provided with a grounding device 20 in order to avoid unwanted charging of the device, to avoid impairments of the ion discharge and to improve the safety of the device operation. 2, the earthing device 20 in the region of the functional head 4 may have a grounding surface 21 ("third grounding surface") which prevents the construction of high charge fields in the region of the functional head 4, in particular in the area of the hair processing device 5. In the embodiment According to Figure 2, the grounding surface 21 is directly connected to the hair processing device 5, wherein it is designed as a carrier and sitting under the hair processing device 5, which is fixed thereto, see Figure 2. The grounding surface 21 is advantageously made of a metal surface and / or a The grounding surface 21 may be connected to the ground potential of the voltage circuit, eg via ground components arranged in the interior of the device.

Alternatively or additionally, the functional head-side grounding surface 21 may also have a metal surface body arranged on the edge of the bristle field 6, preferably in the form of a metal strip, which annularly surrounds the bristle field 6 or, as shown in FIG. 3, surrounds a U-shape from three sides. The bristle field 6 and the remaining body of the functional head 4 may be non-conductive, in particular made of plastic. In the case of a grounding surface 21 at the edge of the bristle field 6 according to FIG. 3, the grounding surface 21 surrounds a sufficient part of the bristle field 6 in order to limit charges arising there to a sufficient extent. Advantageously, the metal strip will extend along at least 50% of the circumference of the hair processing device 5.

As shown in FIGS. 4 and 5, the hair care appliance 1 can also have a plurality of ion outlets 11 on its rear side 8 of the appliance, wherein in the illustrated embodiment According to FIGS. 4 and 5, two ion outlets 11 are provided which, viewed in the longitudinal direction of the device, are arranged at their own height and are positioned symmetrically relative to one another with respect to the longitudinal center plane 18. Advantageously, the ion outlets 11 are arranged at the edge of the functional head back, wherein they are inclined at an angle of the order of 60 ° to 120 °, preferably about 90 ° to each other to produce a uniformly distributed ion cloud. In the illustrated embodiment, the ion outlets 11 are aligned with their main exit direction 18 parallel to the surface of the rear of the device 8, so that the ions emerge substantially parallel to the back of the functional head. In the illustrated embodiment, the ion outlets 11 allow the ions to emerge in diverging directions in order to distribute an ion cloud uniformly over the functional head 4 or its rear side.

As an alternative to the embodiment according to FIGS. 4 and 5, a plurality of ion outlets 11 may also be arranged in the longitudinal center plane 18, cf. Figures 6 and 7. Advantageously, the two ion outlets 11 are oppositely directed, wherein they are arranged on opposite sides in edge regions of the functional head back, see. FIGS. 6 and 7 in order to allow an ion cloud which arises over the functional head rear side to emerge.

Advantageously, the two ion outlets 11 may be differently inclined to the surface of the rear of the device. While an ion outlet with its main exit direction 18 is aligned substantially parallel to the surface of the rear of the device 8, the other ion outlet 11 is slightly inclined at an acute angle to said surface of the rear of the device, preferably at an angle of 0 ° to 40 °, in particular 10 ° to 30 ° , As FIGS. 6 and 7 show, it may be particularly advantageous if the ion outlet 11 arranged in the transition region between the handle 3 and the functional head 4 is slightly inclined, while the ion outlet 11 arranged at the end of the functional head back remote from the handle 3 is parallel to the Rear of the device 8 may be arranged.

As shown in Figures 8 to 10, the aforementioned grounding device 20 advantageously also includes a ground plane 22 ("first ground plane") associated with the ion outlet 11. Specifically, this ground plane 22 is provided on an outer surface of the outlet housing 13 housing the ion emitter or its emitter As is best shown in FIGURE 8, the box-shaped outlet housing 13, roughly speaking, comprises a mouth side 14 forming an end face, in which an outlet opening 17 is provided for the exit of the emitted ions. The high-voltage element 12 is arranged centrally in the outlet housing 13 and ends shortly before said outlet opening 17 in the interior of the outlet housing 13, cf. Figure 10. The high voltage element 12 typically comprises or consists of a wire, while the outlet housing is made, for example, of plastic (the schematic Figure 10 does not disclose material differences).

In the embodiment according to FIGS. 8 to 10, a side surface 16, which is peripheral on the high-voltage element 12, is provided with the grounding surface 22. This may, according to FIGS. 8 to 10, be a bottom side of the outlet housing 13, which faces the appliance base body 2. Alternatively or additionally, this may also be a side wall surface 16 of the outlet housing 13, as shown in FIG.

According to FIGS. 8 to 10, the entire bottom side of the outlet housing 13 is designed as a grounding surface 22, in particular in the form of a metal surface, wherein the housing body may otherwise be non-conductive and in particular made of plastic. As FIG. 11 shows, the corresponding surface-in the case of FIG. 11 the bottom-side side surface-of the outlet housing 13 may also be provided only partially with the grounding surface 22, i. the grounding surface 22 does not necessarily cover the entire side surface, cf. FIG. 11.

Also in the embodiment according to FIG. 12, only about half of the side surface 16 is designed as a grounding surface 22.

As FIG. 13 shows, the rear side of the outlet housing 13, which lies opposite the mouth side 14, can also be designed as a grounding surface 22.

FIG. 14 shows a further embodiment. Here, mutually opposite side surfaces 16 of the outlet housing 13 are each provided with a ground surface 22, wherein in the illustrated embodiment these are formed only in the form of a strip partially covering the side surfaces 16.

A hair care appliance 1 according to a further embodiment of the invention is shown in FIG. 15. Unless otherwise described, this hair care appliance may correspond to the preceding embodiments, corresponding reference numerals being used in FIG. 15 for corresponding components. Essentially, the hair care device according to FIG. 15 differs from the previous ones by the fact that the entire rear side of the functional head is earthed. The housing component 108, which forms the back of the functional head 4 and surrounds the ion outlet 11, is made of non-conductive material, in particular of plastic, so that the housing component 108 can be electrostatically charged per se. However, said housing member 108 is grounded through contact with the ground potential of the high voltage circuit, whereby the electrostatic charge is not impossible, but sufficiently limited, so that the counter electric fields generated by charging are so small that they do not propagate the ions from the ion outlet hinder. In this case, the electrical grounding can take place via the grounding surface 122 ("second grounding surface") .The grounding surface 122 can also be designed as an electrically contacted screw in a screw dome in the housing component 108. Alternatively or additionally, a pressure of a metal electrode can be applied to the housing component 108 In both cases, therefore, a grounding surface connected to the ground potential is provided on the housing component 108 in order to prevent or suppress its electrostatic charge.

As shown in FIG. 15, the grounded casing member 108 extends in the vicinity of the ion outlet 11 substantially over the entire rear body surface of the apparatus, or portion thereof, above which the ion cloud exiting the ion outlet 11 propagates. In this case, the grounded housing component 108 extends from a rear side of the ion outlet 11 facing away from the outlet side 14 of the ion outlet 11, in particular over a large area, up to the ion outlet 11, ie. in the exit direction of the ions from said ion outlet 11, downstream of said ion outlet 11, cf. Fig. 15. The ion outlet 11 forms, so to speak, an island in the surface of the grounded housing member 108, wherein the larger part housing member 108, in the illustrated embodiment more than two-thirds of the housing member 108, on the outlet side of the ion outlet 11, see. Fig. 15.

Said ion outlet 11 is integrated in said housing member 108, in particular, the latter bulges domed to make room for the outlet opening 17 of the ion outlet 11, which is formed in the illustrated embodiment of a sleeve 170, preferably made of plastic, the ion emitter enclosing the outlet side, cf. Fig. 15.

Instead of the full-area grounding of the housing component shown in FIG. 15 in the exit region of the ion emitter, as shown in FIG. 16, in the vicinity of the ion discharge Ses 11 also be provided a plurality of separate housing components 108 a and 108 b, of which at least one is grounded, while at least one other is not grounded. The ungrounded parts can become electrostatically charged, which deflects the ions. In contrast, the ions can spread undisturbed over the grounded parts, so that overall control of the ion cloud is achieved. The pattern of grounded and ungrounded housing components in the vicinity of the lone nauslasses 11 forms a lonenleitvorrichung insofar.

As shown in FIG. 16, this lonenleitvorrichtung or the pattern of grounded and ungrounded housing components 108 a and 108 b advantageously be arranged symmetrically to the longitudinal center plane 18 of the hair care device 1 or be formed. Concretely, Fig. 16 shows a central, from the ion outlet 11 away trapezoidal widening housing member 108 a, which is grounded in the aforementioned manner. This central, strip-shaped housing component 108 a is flanked on the right and left by two lateral housing components 108 b, which remain ungrounded and thus can charge electrostatically. In this embodiment, the ion guide device forms, as it were, an exit channel or corridor, which permits a targeted ion exit and suppresses excessive lateral spreading. Depending on the application, however, other patterns of grounded or ungrounded housing components can be provided in order to achieve a suitable depending on the application control of the spread of the ion cloud.
