Description

nose hair trimmer

The invention relates to a nose hair cutter of the type mentioned in the preamble of claim 1 for cutting nose hair.

Nose hair protruding from the nose is often perceived as unaesthetic, especially in the case of intensive nasal hair growth, from which a cosmetic motivation for shortening the nose hair is derived.

There is no medical indication for trimming nose hair, as nose hair filters out coarser components from the air and thus protects the respiratory tract. It is therefore recommended not to completely remove the nasal hair, as can be done, for example, with a corresponding laser radiation.

The shortening of nose hair is basically medically harmless and various methods are known for this. One of these methods is the so-called plucking, in which the nose hairs are torn out of the skin, e.g. using tweezers. However, this method is not recommended because, in addition to the immediate pain caused, health problems can also arise. Therefore, this method can be associated with the development of inflammation or boils.

Forcibly removing nasal hair can create lesions that allow bacteria to enter the bloodstream and lead to more serious health problems. The same applies to nose hair removal with wax.

Flaming nose hair is also known, but due to the increased risk of injury, for example with regard to burns or damage to the nasal mucous membranes, this is not an ideal way of shortening nose hair, especially if this is done without trained specialist staff or by amateurs.

Nose hair trimmers of the type in question are used to gently shorten nose hair, with which, for example, hair located at the entrance to the nose or in the nasal vestibule can be cut as gently as possible without causing skin irritation or inflammation. They are known in various embodiments and are also referred to, among other things, as nose hair trimmers. Nose hair trimmers of the type in question can initially be differentiated into those with a rotating blade and those with a stationary blade or a blade that is fixed to the cutting head or base body.

Furthermore, a distinction can be made between nose hair trimmers with and without their own drive for moving the blade.

In the case of nose hair trimmers with their own drive, the function depends on an energy source, which can be formed by a battery, for example. Nose hair trimmers without their own drive have the advantage that they can be used independently of an energy source and thus with a hand movement for trimming nose hair.

Nose hair trimmers are also suitable for removing hair on the outer auditory canal, so their use is not necessarily limited to the nose.

Nose hair trimmers of the type in question are usually equipped with a base body formed along a body axis in order to make the design as compact as possible and to simplify handling when using it.

At a first end of the body, the base body has a cutting head which is set up and designed for cutting the nose hair. Furthermore, the base body has a handle which is connected to the cutting head and extends from the cutting head in the direction of a second end of the body. The handle is used to guide the movement of the cutting head in a simple manner, for example to facilitate insertion into the nostril and alignment in addition to cutting.

For cutting the nose hair, a blade with a cutting edge running in the axial direction to the body axis for cutting the nose hair is arranged on the cutting head, which promotes a compact design.

In addition to the problems mentioned above, the known nose hair trimmers have the problem, among other things, that shortening the nose hair does not have the desired cutting success and is time-consuming, since several cutting processes are often necessary to achieve the desired shortening of the nose hair. The object of the invention is to provide a nose hair trimmer that enables nose hair to be trimmed efficiently and is also safe to use.

To solve the problem, the invention moves away from the idea of changing the blade design compared to the known designs.

Furthermore, the invention breaks away from the idea of using a rapidly rotating cutting head in order to achieve a correspondingly better cutting result. In this context, it has been found that a cutting head with a rotating blunt blade pulls the nose hair out of the skin and causes the problems known from plucking.

The same applies to the scraping of nose hairs on the skin surface, from which the invention also turns away.

Furthermore, the invention moves away from using tools such as a glow wire to trim nose hair. The invention also separates itself from the approach of heating the blade or cutting edge with a heat source in order to positively influence the cutting result.

Rather, the invention solves the task set for it with a surprisingly effective approach in that the cutting performance of a nose hair trimmer designed according to the invention is improved by a clever arrangement and orientation of the blade on the cutting head, so that a large number of nose hairs are trimmed simultaneously and safely during a cutting process.

The invention thus succeeds in increasing the effectiveness of the cutting of nose hair, as a result of which the cutting process can also take place in a short time and is therefore efficient with a nose hair cutter according to the invention.

The invention provides that the cutting edge of the blade protrudes at least in sections from a surface of the cutting head extending in a circumferential direction to the body axis in such a way that the cutting edge cuts the nose hair fed to it on an outside of the cutting head.

In the context of the invention, a surface that faces away from the body axis and points outwards is to be understood as a lateral surface or outer surface from which the cutting edge emerges at least in sections and protrudes for contact with the nasal hair. It is further provided according to the invention that the cutting edge extends in a first body plane running in the radial direction to the body axis and a blade mirror facing the body axis is at least partially set at an acute angle to the first body plane.

The acute angle of attack of the blade according to the invention to the first plane of the body has the advantage that deformation of the cutting edge of the blade while cutting the hair can be kept low or prevented, since its resistance to deformation is improved compared to a blade extending radially to the body axis. The invention thus also allows the use of thin blades with a thickness of less than 1 mm, which can be designed, for example and in particular, in the manner of a razor blade blade.

A cutting edge extending in the axial direction of the body axis causes a wide cutting area to be formed on the cutting head, so that a blade arranged on the cutting head in this way can simultaneously cut a large number of nose hairs with the blade and thus shorten them.

Furthermore, the arrangement of the cutting edge on the outside of the cutting head makes it possible to shorten the nose hair close to the skin surface on which the respective hair protrudes. The invention thus allows the period of time until the nose hair is next to be shortened to be lengthened, as a result of which the nose haircut has a more lasting effect.

Finally, by aligning the blade mirror inclined according to the invention, the cutting edge emerges in the cutting area of the cutting head with its cutting edge inclined to the surface of the cutting head, which extends in the circumferential direction around the body axis. The cutting edge thus meets the nose hair fed to it via the surface of the cutting head at an acute angle of inclination.

Surprisingly, it turned out that the arrangement of the blade on the cutting head according to the invention achieves efficient cutting of the nose hair. As a result, a repeated cutting operation to shorten the nose hair is unnecessary, which also minimizes the risk of injury. In addition, tearing out of the nose hair during the cutting process is avoided.

Within the scope of the invention, it has been shown that an angle of attack of between 25° and 75° brings about good cutting performance. The cutting performance can in particular be increased by the angle of attack having a value between 30° and 60°. Furthermore, it has been shown that the cutting performance is particularly increased when the angle of attack has a value between 44° and 46°. In the context of the invention, an optimal cutting performance was determined in that the angle of attack has a value of 45°. Therefore, the aforementioned angles of attack are taken into account in a further advantageous development of the invention.

The invention has shown that the blade alignment provided according to the invention results in improved cutting of nose hair compared to blades whose cutting edge is aligned parallel to the body axis and whose blade face extends in a radial direction to the body axis.

Against this background, an advantageous further development of the invention provides that the cutting edge of the blade is inclined at an acute angle to the body axis in the direction of the first body end of the base body. The radial distance between the cutting blade and the body axis is thus reduced in the direction of the first body end of the base body, as a result of which a compact design of the cutting head is made possible.

In the context of the invention, it has proven to be advantageous that the arrangement of the blade according to the invention at an acute angle of inclination to the body axis supports easy insertion of the nose hair trimmer into a nasal cavity. Furthermore, it has been shown that the cutting of the nose hair leads to a better result due to the arrangement of the blade on the cutting head according to the invention.

In a further advantageous development of the invention, it is provided that the angle of inclination has a value between 5° and 20°, in particular between 5° and 15°, preferably between 8° and 12°, most preferably a value of 10°.

Within the scope of the invention, it has been shown that the cutting performance can be increased by appropriate inclination of the cutting edge to the body axis in accordance with the aforementioned values. It is also possible to design the cutting head in accordance with the inclination of the cutting edge, in order to also achieve improved handling of the nose hair trimmer for cutting the nose hair in a compact design. It has been shown that by arranging the cutting head of the nose hair trimmer according to the invention, the nose hair can be cut safely and also at a sufficient depth in the nasal cavity, so that a nose hair trimmer designed according to the invention implements efficient handling for shortening or cutting nose hair.

For easy handling of a nose hair trimmer formed according to the invention, the handle can be designed and connected to the trimmer head in various ways.

The invention provides, for example and in particular, for the handle to be shaped like a handle along the common body axis with the cutting head, so that the handle enables a very compact design of a nose hair trimmer according to the invention and also makes it easy to use.

The cutting of nose hair by means of a nose hair trimmer according to the invention is based on a relative movement between the nose hair and the blade, so that when there is contact between the nose hair and the cutting edge, the blade cuts the nose hair as a result of the movement relative thereto. In order to generate a relative movement between the nose hair and the blade, various options for generating the movement can be used according to the invention.

In order to facilitate easy handling, the invention provides that a rotary movement or torque can be applied to the cutting head via the handle, whereby the cutting head rotates about the body axis during cutting and thus the necessary relative movement between the blade or its blade cutting edge and the nose hair causes.

The blade is fed with its cutting edge to the nose hair, which is guided on the surface of the cutting head, and brought into contact for cutting.

Accordingly, the invention eliminates the need for a dedicated drive for blade movement relative to the nasal hair. This saves a motor drive, which in turn requires an energy source, e.g. a battery, to operate it.

According to the invention, a hand movement generates a relative movement of the cutting edge to the nose hair, which is important for the cutting process. In this It has been shown that the handle can be held very easily between the thumb and index or middle finger. A relative movement between the thumb and index or middle finger can cause a rotary movement of the cutting head. Alternatively, the relative movement can also be generated by rotating the hand.

Within the scope of the invention, a rotary movement of the cutting head or the blade is also to be understood as a rotary movement of less than 360°. Within the scope of the invention, it has been shown that a rotary movement well below 180°, preferably already up to 120°, is sufficient to cut the nose hair.

Against this background, it is provided in a further advantageous development of the invention that the cutting head and the handle are connected to one another for a rotary movement transmission between them. Therefore, the handle is set up and designed, for example and in particular, as a turning handle for the cutting head. Accordingly, torque can be transmitted from the handle to the cutting head.

In order to prevent cut injuries when cutting nose hair, a further advantageous development of the invention provides that at least one first, in particular channel-shaped, guide groove for the nose hair is formed on the surface of the cutting head and extends at least in sections longitudinally in a circumferential direction to the body axis, into which the Blade with a blade forming the cutting edge protrudes at least in sections.

Thus, the guide groove or its course in the circumferential direction is arranged transversely to the cutting edge or a cutting edge of the blade forming the cutting edge.

Within the scope of the invention, the at least one guide groove can, for example and in particular, extend longitudinally around part of the circumference of the cutting head.

The guide groove according to the invention advantageously means that the nose hairs can be fed to the cutting edge in bundles. Furthermore, the use of such a guide groove is to enable safe cutting of the nose hair by means of a nose hair trimmer according to the invention, in that the cutting edge does not protrude outward beyond the guide groove, but rather extends inside the guide groove. The invention thus provides that the cutting edge is arranged in the guide groove in such a way that the skin of the nose does not penetrate up to the cutting edge into the guide groove when the nose hair is being cut.

As a result, the guide groove offers the advantage that when a nose hair trimmer according to the invention is used properly, cutting contact between the cutting edge and the skin of the nose is prevented. This safely prevents cut injuries.

The at least one guide groove provided according to the invention advantageously has the effect that the nose hair is fed to the blade in a bent state or a state of tension in the circumferential direction of the axis of rotation when the cutting head moves, in particular a rotary movement of the cutting head, for cutting nose hair. As a result, it is achieved according to the invention that the nose hair can be cut better or the cutting success is increased.

In order to better guide the nose hair to the cutting blade, a further advantageous development of the invention provides that the guide groove extends longitudinally along the circumferential direction in such a way that its cross section decreases at least in sections, in particular continuously, with increasing distance from the cutting edge in the circumferential direction to the body axis. The invention provides, for example and in particular, for the cutting edge to be arranged in the region of the guide groove in which it has its largest cross section and the cross section of the guide groove is reduced in sections with increasing distance from the cutting edge in the circumferential direction to the body axis.

The invention thus achieves the advantage that the nose hairs are aligned to the cutting edge by a rotary movement of the cutting head about the body axis and fed to the cutting edge in a correspondingly aligned manner.

In order to avoid damage to the nose, the invention also includes, for example and in particular, a haptic marking arranged on the base body, which can be felt in particular through the nose or the edge of the nose opening. Such a haptic marking can be implemented more advantageously by the guide groove or the or one of the guide grooves. Such a marking favored easy handling of a nose hair trimmer according to the invention. Furthermore, a haptic marking according to the invention can also be realized by separate shoulders or recesses on the cutting head. A further improvement in feeding the nose hair to the cutting edge can be achieved within the scope of the invention, for example and in particular by an at least partially increased or high surface quality of the guide groove, in that the surface of the guide groove (guide groove surface) formed on the groove bottom and the groove sides is at least is as smooth as possible in sections, for example and in particular has an arithmetic mean Ra of less than or equal to 0.1 m in accordance with the version of DIN EN ISO 4287 that is currently valid or in the calendar year 2020.

In order to increase the safe use of a nose hair clipper for cutting nose hair, a further advantageous development of the invention provides that at least one second guide groove or a plurality of guide grooves is/are formed on the surface, each of which extends longitudinally at least in sections parallel to the first guide groove/ and into which a cutting edge forming the cutting edge protrudes at least in sections transversely to the circumferential direction of the body axis. The advantage of using two or more guide grooves according to the invention is that the area in which the cutting edge protrudes outwards and can be reached via the guide groove opening is reduced without significantly reducing the cutting performance of a nose hair trimmer according to the invention. According to the invention, this is achieved in that, instead of one large cutting area for cutting the nose hair, several comparatively smaller cutting areas are formed by the guide grooves, which are arranged next to one another.

In order to better support a cutting movement of a nose hair trimmer according to the invention, the blade is held on the cutting head so that it cannot move, in particular so that it does not rotate. For this purpose, a further disadvantageous development of the invention provides that a cavity is formed inside the cutting head, into which the blade protrudes at least in sections, in particular with a large part of the surface of the blade, and is held by holding means, in particular in a positive and/or non-positive manner . A movement-proof holding on the cutting head can be achieved by various holding means. In the simplest case, the blade can be held by latching means, so the first latching means are formed in the cavity and corresponding latching means on the blade, so that when these latching means latch with one another, the blade is held or fixed on the cutting head. In order to increase the handling of a nose hair trimmer according to the invention, a further advantageous development of the invention is characterized in that the cutting head tapers in the axial direction to the body axis at least in sections in the direction of the first body end, in particular conically, preferably in the manner of a truncated cone. As a result of this shaping of the cutting head according to the invention, it is advantageously achieved that a nose hair cutter according to the invention also cuts nose hair located deeper in the nasal cavity. A tapering or conical shape of the cutting head can also limit the insertion of a nose hair separator according to the invention in such a way that damage to the nasal mucous membranes does not occur. In this respect, the invention makes it possible to be able to easily and safely shorten nasal hair not only at the nasal opening but also in the nasal vestibule.

Furthermore, the invention also includes the fact that at least the cutting head is shaped symmetrically to one plane, in particular to the first body plane, which in turn results in handling advantages when used during the cutting of nose hair.

In order to promote simple and cost-effective production of a nose hair trimmer according to the invention, a further advantageous development of the invention provides that the base body is formed from two base body parts of the same shape. In addition to production, this also benefits storage for components of a nose hair trimmer according to the invention.

To further improve the cutting performance of a nose hair clipper, a further advantageous development of the invention provides that the cutting head has at least two blades which are arranged offset from one another in the circumferential direction of the body axis, in particular at an angle of 180°.

The invention takes into account, for example and in particular, that two similar or identical blades are used, as a result of which the cutting success is increased and this is implemented cost-effectively.

The invention also takes into account that when two or more blades are used, these are, for example and in particular, spaced apart from one another and are preferably arranged on the cutting head without touching one another, which facilitates their assembly on the cutting head Furthermore, the invention provides, for example and in particular, that the blades are arranged on the cutting head in such a way that the cutting edge of the respective blade extends longitudinally in the same plane of the body. This in turn favors a compact design of the cutting head.

The use according to the invention of identically shaped or identical parts reduces the production costs and facilitates the storage of the components of a nose hair trimmer according to the invention.

The main body of a nose hair trimmer according to the invention can be made of different materials. It is thus possible to produce the nose hair trimmer from a plastic. It is also possible within the scope of the invention to use different plastics or types of plastic. Different sections of the base body can thus be formed by different plastics, so that the plastic used in each case supports the performance of the relevant function as optimally as possible. The use of plastics enables the realization of a low weight, good corrosion resistance or good resistance to water and detergents and good recycling.

With regard to better recycling, the use of a uniform material, in particular plastic, is also provided for the formation of the base body within the scope of the invention.

Furthermore, it is possible to use renewable raw materials for the formation of a nose hair trimmer according to the invention. Wood or bamboo materials, which have the advantage that they have a high ecological value, have proven to be very suitable.

In addition, it is also possible within the scope of the invention to combine different materials with one another in order to implement a nose hair trimmer according to the invention. The invention is explained in more detail below with reference to the attached drawing, in which an exemplary embodiment of a nose hair cutter according to the invention is shown as representative of a large number of nose hair cutters formed according to the invention.

All features claimed, described and shown in the drawing form the subject matter of the invention, independently of one another and in any combination with one another, regardless of their summary in the patent claims and their back-references and independently of their description or representation in the drawing . Therefore, the features are not tied to the constellation explained below, but can also form a nose hair trimmer according to the invention isolated from one another or in a different combination.

The figures of the drawing show a possible embodiment of a nose hair trimmer according to the invention, each in a schematic representation. The representations in the figures are therefore in particular not necessarily true to scale, so that the scales selected in each case in the figures can also be different from one another.

For a better overview, the illustrations are concentrated on the elements/components/components that support understanding, with the same or corresponding components/components or elements being provided with the same reference symbols in the figures.

For a better overview, not all elements/components/components are always provided with reference numbers in the figures, with the assignment resulting from the same representation or a representation adapted according to the view. It shows:

7 shows a blade of the embodiment of a nose hair trimmer according to the invention in a view similar to FIG. 2, the view being concentrated on the blade.

In the following, the description is reduced to the differences between figures with the same or similar structure for a better overview.

The features illustrated on the basis of the figures also apply analogously and comprehensively as well as isolated from one another for further nose hair trimmers formed according to the invention. The invention is therefore not limited to the exemplary embodiments or relationships described and shown. 1 shows a schematic representation of a nose hair trimmer 2 according to the invention in a side view in a vertical orientation. In the following, the exemplary embodiment of a nose hair trimmer 2 according to the invention is also referred to in abbreviated form as a nose hair trimmer 2 .

The nose hair trimmer 2 is used to trim nose hair (not shown), and it can also be used to trim hair in ear holes.

The nose hair trimmer 2 is equipped with a base body 6 formed along a body axis 4, which has a cutting head 10 at a first body end 8 and a handle 12 connected thereto, which extends from the cutting head 10 in the direction of a second body end 14 of the base body 6.

The cutting head 10 tapers in the axial direction 11 to the body axis 4 at least in sections in the direction of the first body end 8 and is shaped in the manner of a truncated cone in this exemplary embodiment.

A blade 16 with a cutting edge 18 running in the axial direction 11 to the body axis 4 for cutting the nose hair is arranged on the cutting head 10 for cutting the nose hair. In addition to this blade 16, another blade 16 is arranged on the cutting head 10, which is shown below and is not visible there due to the view chosen in FIG. However, the invention is not limited to the use of two blades, so that, for example and in particular, only one blade can be used. Accordingly, a nose hair trimmer 2 according to the invention would be set up and configured accordingly.

The cutting edge 18 is directed transversely to the plane of the drawing in FIG. 1 and its arrangement is illustrated in FIG. 2 and FIG. 3 on the basis of a further view.

The blade 16 is arranged on the cutting head 10 in such a way that the cutting edge 18 of the visible blade 16 protrudes at least in sections from a surface 22 of the cutting head 10 that extends in a circumferential direction 20 to the body axis 4 in such a way that the cutting edge 18 cuts the nasal hair fed to it on an outer side 24 of the cutting head 10 cuts. This arrangement is further illustrated and explained for both blades 16 with reference to FIG. 2 .

On the surface 22 of the cutting head 10 is a plurality of in the circumferential direction 20 to the body axis 4 elongated channel-shaped guide grooves 28 (uniformly provided with the reference numeral 28) formed for the nose hair, in which the blade 16 protrudes at least in sections with a cutting edge 26 forming the cutting edge 18 .

The guide grooves 28 extend longitudinally parallel to one another in the circumferential direction 20 , the cutting edge 26 forming the cutting edge 18 protruding into the respective guide groove 28 at least in sections transversely to the circumferential direction 20 of the body axis 4 .

The respective guide groove 28 extends longitudinally along the circumferential direction 20 on the surface 22 of the cutting head 10 such that its cross section, which extends transversely to the circumferential direction 20, steadily decreases as the distance in the circumferential direction from the cutting edge 18 increases. The respective guide groove 28 extends on both sides of the blade edge in the circumferential direction to the body axis, so that the reduction in the cross section of the guide groove in question is also correspondingly evident on both sides in this exemplary embodiment, whereby the effect of the guide groove is independent of the direction of rotation.

The guide grooves 28 are designed in the same way, with the cutting edge 18 of the blade 16 not protruding beyond the respective guide groove 28 .

For better guidance of the nasal hair on the surface 22 of the cutting head 10, the respective guide groove 28 has at least in sections a guide groove surface 30 which is provided with a high surface quality, in particular a finely finished, preferably polished, guide groove surface which is part of the surface 22 of the cutting head 10 . The guide groove surface 30 delimits the guide groove 28 in particular in the radial direction 32 and axial direction 11 to the body axis 4. It is identified uniformly for all guide grooves with the reference numeral 30.

FIG. 2 shows the nose hair trimmer 2 in a schematic side view, in which the angle of inclination β is illustrated. The components of the nose hair trimmer 2 are entered only once or a few times as representative, partly for the sake of a better overview. They apply equally to the same components that can be assigned to one another due to the symmetrical representation with respect to the body axis 4 .

The cutting edge 18 extends in a first body plane 34 running in the radial direction 32 to the body axis 4 . In other words, the body level 34, as can be seen in FIG.

Fig. 2 shows that the inclination of the blade 16 or its cutting edge 18 at an angle of inclination ß to the body axis 4 results in a distance of the cutting edge 18 in the radial direction 32 to the body axis 4 from a second body end 14 in the direction of the first body end 8, at least in sections reduced.

In the nose hair trimmer 2 shown, the cutting edge 18 is elongated in a straight line, so that the radial distance from the body axis 4 decreases steadily and, in this exemplary embodiment, linearly.

In the nose hair trimmer 2 shown, the angle of inclination β has a value of 10°.

Therefore, the distance between the cutting edge 18 in the radial direction 32 is smaller with its cutting edge end 38 facing the first body end 8 than with its cutting edge end 40 facing the second body end 14.

FIG. 3 makes it clear that a blade mirror 42 facing the body axis 4 is set at an acute angle (a) to the first body plane 34 at least in sections, as is symbolized in FIG. 3 . The angle of attack (a) is 45° in this exemplary embodiment, as a result of which an optimal cutting result can be achieved within the framework.

As can be seen in FIG. 3, on the cutting head 10 of the nose hair trimmer 2 there are two identically designed blades 16 (uniformly provided with the reference numeral 16) which are offset from one another in the circumferential direction 20 to the body axis 4 at an angle of 180°.

The blades 16 are spaced apart from one another and are arranged on both sides of the body axis 4 . In this exemplary embodiment, the blades 16 are arranged at a distance from one another in the radial direction 32 and in the circumferential direction 20 with respect to the body axis 4 . The blades 16 are arranged without touching each other.

As shown in FIG. 3, the blades 16 used are designed at least geometrically the same.

Fig. 4 shows the nose hair trimmer 2 in a handling position in which it is held by a human hand 44, symbolized in Fig. 4, on the handle 12 is held. In the handling position shown, it is illustrated that the thumb 46 is arranged on one side of the handle 12 and a pointer or middle finger 48 , 50 of the hand 44 is arranged on an opposite side of the handle 12 . The cutting head 10 and the handle 12 are connected to each other for the transmission of rotational movement and torque transmission between them.

A rotary movement of the hand 44 causes the cutting head 10 to rotate about the body axis 4 via the handle 12, to which the cutting head 10 is connected in a rotationally fixed manner. In a position of use in a nose (not shown) there is a relative movement between nose hair and cutting head 10, as a result of which the nose hair comes into contact with the cutting edge 18 via the surface 22 of the base body 6 and is cut accordingly.

In Fig. 5 it can be seen that in the nose hair trimmer 2 the blade 16 is held by holding means 54 (symbolized by a triangle in Fig. 5) on the cutting head 10 in such a way that the cutting head 10 and the blade 16 are connected to one another in a rotationally fixed manner.

The components of the nose hair trimmer 2 are entered only once or a few times as representative, partly for the sake of a better overview. They apply equally to the same components that can be assigned to one another due to the symmetrical representation with respect to the body axis 4 . In FIG. 5, only one blade 16 is symbolically shown and identified as a representative.

For this purpose, a cavity 56 is formed in the interior of the cutting head 10, into which the respective blade 16 protrudes at least in sections, in particular with a large part of the surface of the respective blade 16 (as illustrated in Fig. 5 and also in Fig. 2), and which is held by the holding means 54 in of the cavity 56 is held in a positive or non-positive manner.

6 shows that the cavity 54 can also extend, for example, into the handle 12 and form a space for a taring body 58 which can be arranged therein as additional weight for influencing the center of gravity of the nose hair trimmer 2 . In a simple design, the taring body 58 can be formed by a cylindrical weight, for example made of metal. The handling of the nose hair trimmer 2 during the cutting of the nose hair can thus be positively influenced. According to the invention, the base body 6 can be formed from different materials. It is also possible to use different materials in different sections. For example, the handle 12 can be made of bamboo, while the cutting head 10 is made of a plastic.

In the exemplary embodiment shown, the base body 6 is made of a plastic, with the base body 6 being formed from two base body parts 60, 62 of the same shape, which form the base body 6 when connected to one another. In FIG. 6, the base body parts 60, 62 are shown radially spaced apart from the body axis 4, in which they are arranged relative to one another in a preassembled state.

The base body parts 60, 62 are connected by a combination of positive and non-positive locking, with a snap connection being used here. In this exemplary embodiment, the base body parts 60, 62 are arranged next to one another on the first body plane 34 in order to form the base body 6 when connected to one another.

Therefore, in this exemplary embodiment, the base body 6 is designed symmetrically to the first body plane 34 .

7 shows one of the blades 16, which has a trapezoidal basic shape. The cutting edge 26 is formed with the cutting edge 18 on one side, and the back of the blade 64, which has no cutting edge 26, is formed on the opposite side. The blade face 66 is formed between the back of the blade 64 and the cutting edge 26 . The blade face 42 can also be referred to as the flank and, taken by itself, is the part of the blade 16 without the cutting edge or the unground part.

The blades 16 used each have a cutting edge 16 with a double-sided blade bevel, with only one blade bevel being recognizable in the view chosen in FIG.

Two recesses 66 , 68 are formed on the blade mirror 42 and serve to arrange the respective blade 16 on the cutting head 10 . In the mounted state of the blade 16 on the cutting head 10, pins (not shown) extending from the cutting head 10 into the cavity 56 engage in the recesses 66, 68, as a result of which the respective blade 16 is held in a non-rotatable manner.

In addition to the pins, the holding means 54 also include a hold-down device (not visible in the illustrations), which presses the blade 16 against the cutting head 10, see above that the blade 10 in the interaction of the pins and recesses 66, 68 on the cutting head are held in a non-moving, in particular non-rotating, manner.

Within the scope of the invention, the aforementioned features can be designed and combined with one another within very broad limits. For a design of a nose hair trimmer 2 according to the invention, the above-described features as described in the exemplary embodiment can also be used and combined with one another independently of the combination described in the exemplary embodiment.

The use of the features described in the exemplary embodiment is therefore not a mandatory combination of features, so that one or more features can be dispensed with to form a nose hair trimmer 2 according to the invention.

Therefore, the invention is not limited to the exemplary embodiment shown and the design explained thereon.
