Description

[Technical Field]

[0001] The present invention relates to a hair collector for a hair-cutting device having a cutting element, a hybrid hair-cutting device having a razor guard to which a cutting element and a hair collector are connected, a hybrid hair-cutting device having a razor guard to which a cutting element and a hair collector are integrated, and a method of collecting hair from a hair-cutting device having a cutting element. [Background technology]

[0002] Hair cutting instruments are used to cut human hair during trimming and shaving. Summary of the Invention [Problem to be solved by the invention]

[0003] Some hair-cutting devices have both shaving and trimming functions, which can be called "hybrid cutting systems." Such hair-cutting devices, which can be hybrid hair-cutting devices, can have cutting elements that operate at very high frequencies and, as a result, reach high speeds. The movable cutting element or cutter can reciprocate at high vibration frequencies, on the order of 7,000 times per second. This high cutting frequency results in high energy being transferred to the hair during the cutting action, which imparts high hair velocity and causes a large amount of flying particles of cut hair. This flying particles can clutter the grooming environment.

[0004] This issue needs to be addressed.

[0005] Patent application DE 19727095 A1 discloses an electric shaver in which the shaving unit has a foil shaver arranged next to hair styling elements, with an opening appearing between these styling elements and the foil shaver.

[0006] It would be advantageous to have an improved means for mitigating the scattering of cut hair particles from hair-cutting implements, such as hybrid hair-cutting implements.

[0007] The object of the present invention is solved by the subject matter of the independent claims, further embodiments being incorporated in the dependent claims. [Means for solving the problem]

[0008] It should be noted that the aspects and embodiments of the present invention described below also apply to hair collectors for hair-cutting implements with cutting elements, hybrid hair-cutting implements with a cutting element and a razor guard to which a hair collector is connected, hybrid hair-cutting implements with a cutting element and a razor guard to which a hair collector is integrated, and methods of collecting hair from a hair-cutting implement with a cutting element.

[0009] According to a first aspect, there is provided a hair collector for a hair-cutting appliance having a cutting element, the hair collector comprising: The housing and and an attachment portion.

[0010] The housing has a plurality of walls. The attachment portion is configured to attach the hair collector to the hair-cutting device. When the hair collector is connected to the hair-cutting device, a cut hair collection chamber is formed. The cut hair collection chamber includes the plurality of walls of the housing and the cutting element. When the hair collector is connected to the hair-cutting device, the hair collector is configured so that the cutting element can contact the skin of a user of the hair-cutting device.

[0011] Thus, a hair collector is provided that can surround the cutting element of a hair-cutting device, such as a hybrid shaver / trimmer or other device that operates in a reciprocating / trimmer style, and form a closed compartment with the cutting element to collect cut hair.

[0012] In this way, hair cut by hair-cutting devices that operate with rapidly vibrating or high frequency cutting elements and that are capable of cutting and trimming facial and body hair can be collected, even though it would otherwise fly off uncontrollably.

[0013] Thus, the hair collector cooperates with the cutting element to form a compartment for collecting cut hair, but does not interfere with the cutting element and the hair lifting features associated with the cutting element, such as those provided by the guard.

[0014] In one example, at least one sidewall of the walls of the housing has a structure that forms a plurality of openings.

[0015] As an example, when the hair collector is connected to the hair-cutting device, the structure is configured to allow hair to pass through the plurality of openings and into the cut hair collection chamber.

[0016] In other words, a semi-open filtering system is provided, which allows hair to enter the hair collector and be cut, but blocks the hair from exiting the collector after it has been cut.

[0017] In one example, the structure is configured to inhibit hair from passing through the plurality of openings and exiting the cut hair collection chamber.

[0018] The structure thus acts like a funnel, which allows hair to easily enter and be cut, but is difficult to exit.

[0019] In other words, the structure of the hair collection wall, which may be a comb tooth-like element, is shaped to guide the hair when viewed from the direction of hair travel towards the cutting direction and to block the hair when viewed from the opposite direction, for example, this can be done through having a triangular shape with the apex (which may be rounded) pointing away from the cutting element.

[0020] In one example, the total surface area of ​​the structures on the outer surface of the at least one sidewall is less than the total surface area of ​​the structures on the inner surface of the at least one sidewall.

[0021] In other words, the opening in the wall of the hair collector is tapered so that hair can enter but cut hair cannot exit.

[0022] In this way, the directionality of the hair can be gradually influenced and at the same time uncut hair can enter the collection chamber, be cut and then be prevented from leaving the collection chamber.

[0023] In other words, it has grooved walls with teeth that have a larger open outer surface area compared to the open inner surface area, or in other words, the shaper edges of the teeth point outwards.

[0024] In one example, the structure comprises a comb-like structure having a plurality of teeth, the teeth tapering from an outer surface of the at least one sidewall to an inner surface of the at least one sidewall.

[0025] Thus, the tapered teeth allow hair to enter the hair collector and be cut, but prevent the cut hair from exiting. However, because the hair collector does not obstruct the cutting element's contact with the skin, the lifting and cutting performance of the hair-cutting implement, such as a hybrid razor, to which the hair collector is connected is not affected because the teeth do not act at skin level but are located above the cutting element.

[0026] In one example, the angle of the tooth taper is constant.

[0027] Thus, by having a constant angle, there is a continuous reaction force against the moving hair as it moves from the inlet to the outlet through the structure towards the hair collection chamber.

[0028] In one example, the teeth have a triangular cross section.

[0029] In one example, the plurality of openings extend in a longitudinal direction of the at least one side wall, the longitudinal direction being perpendicular to the plane of the cutting element when the hair collector is connected to the hair-cutting appliance.

[0030] In this way, hair can be aligned perpendicular to the skin transversely to the forward movement of the hair collector connected to the hair-cutting device. Hairs of different lengths, such as beard hairs, can enter the hair collector.

[0031] In other words, by disposing a hair collector, which is a comb-like element, between the main housing of the hair-cutting element and the cutting element and over the cutting element, a hair collection space is provided around the cutting element of a hair-cutting tool such as a hybrid hair-cutting system. The cutting element can touch the skin, and the comb-like element is spaced above the skin but does not need to touch the skin. This provides an optimal catch for the cut hair and allows even long hairs to easily move through the opening and be cut.

[0032] In one example, the spatial periodicity of the plurality of openings is configured to be an integer number of times the spatial periodicity of the plurality of openings in the razor guard of the cutting element.

[0033] In one example, a first side wall and a second side wall of the plurality of walls each have a structure, and the first side wall is on an opposite side of the housing from the second side wall.

[0034] Thus, a double-sided hair collector is provided which can be fitted to a hair-cutting implement having a cutting element capable of cutting in both the front and rear directions.

[0035] In one example, when the hair collector is connected to the hair-cutting device, at least two side walls of the plurality of walls define an outer plane at an outer extent of the hair collector, and the hair collector is configured such that when the cutting element contacts the user's skin, the outer surface of the hair collector lies above a surface of the cutting element adjacent the user's skin.

[0036] According to a second aspect, there is provided a hybrid hair-cutting device having a cutting element and a razor guard, the hybrid hair-cutting device being adapted for both shaving and trimming, and having a hair collector according to the first aspect connected thereto.

[0037] According to a third aspect, there is provided a hybrid hair-cutting device having a cutting element and a razor guard. The hybrid hair-cutting device, which is suitable for both shaving and trimming, is integrated with a hair collector. The hair collector has a housing. The housing has a plurality of walls. A cut hair collection chamber is formed with the plurality of walls of the housing and the cutting element. The hair collector is configured to allow the cutting element to contact the skin of a user of the hair-cutting device.

[0038] According to a fourth aspect, there is provided a method of collecting hair from a hair-cutting device having a cutting element, the method comprising the step of connecting a hair collector to the hair-cutting device. The hair collector comprises: The housing and and an attachment portion.

[0039] The housing has a plurality of walls. The attachment portion attaches the hair collector to the hair-cutting device. Collection of cut hair is provided through the formation of a cut hair collection chamber. The cut hair collection chamber has the plurality of walls of the housing and the cutting element. The hair collector is configured to allow the cutting element to contact the skin of a user of the hair-cutting device.

[0040] Advantageously, any benefit provided by any of the above aspects applies to all other aspects as well, and vice versa.

[0041] The above aspects and examples will be apparent from and elucidated with reference to the embodiments described hereinafter. [Brief explanation of the drawings]

[Figure 8] 10A-10C show a plan view of an example of the alignment of the upper hair collector spacing with the lower razor guard spacing, also showing an exemplary cutting element. [Figure 9] 10A-10C show schematic examples of the relative alignment of a hair collector with a razor guard to a cutting element and a user's skin. DETAILED DESCRIPTION OF THE INVENTION

[0043] Exemplary embodiments are described below with reference to the following drawings:

[0044] Figure 1 shows an example of a hair collector 10 for a hair-cutting device 100 having a cutting element 110. Required elements are shown schematically in solid lines, and optional elements are shown in dashed lines. Figure 1 relates to the hair collector 10, but for purposes of representation and context, the hair-cutting device 100 is also shown.

[0045] Continuing to refer to FIG. 1 , the hair collector has a housing 20 and an attachment portion 30. The housing has a plurality of walls 40. The attachment portion is configured to attach the hair collector to a hair-cutting device. When the hair collector is connected to the hair-cutting device, a cut hair collection chamber is formed. The cut hair collection chamber includes the plurality of walls of the housing and a cutting element. When the hair collector is connected to the hair-cutting device, the hair collector is configured so that the cutting element can contact the skin of a user of the hair-cutting device.

[0046] In one example, when the hair collector is connected to the hair-cutting tool, the drive system for the cutting element is at least partially located within the cut hair collection chamber. Thus, by attaching a reservoir directly to the cutting element, a localized hair collection space is provided, and the reservoir or collection chamber encases the blade, including its drive system (driving bridge + excenter), ensuring that cut hairs that would otherwise be scattered due to the high-frequency vibrations are contained. This is shown in more detail in Figures 3 to 6.

[0047] In one example, the attachment portion is configured to attach a hair collector to the cutting element. The attachment portion can operate in a variety of ways, as will be appreciated by those skilled in the art. Further examples of attachment portions are shown in detail in Figures 3-5.

[0048] In one example, the attachment portion is configured to releasably attach the hair collector to the hair-cutting device.

[0049] In one example, a wall 48 of the plurality of walls has an opening into which a connecting portion of a cutting assembly of a hair-cutting tool can be inserted. The cutting assembly has a cutting element. Thus, a hair collector can be placed on the cutting element and then connected to the hair-cutting tool. This is shown in Figure 4, where a hair collector can be placed on the cutting assembly.

[0050] In one example, the hair-cutting appliance has a main housing, and when the hair collector is connected to the hair-cutting appliance, the hair collector is disposed at least partially around the cutting element between the cutting element and the main housing. This cutting assembly and hair collector around the cutting element are shown in more detail in Figures 3-6.

[0051] In one example, the hair-cutting device is a hybrid hair-cutting device configured for both shaving and trimming.

[0052] In one example, when the hair collector is connected to the hair-cutting device, the hair collector is configured so that the cutting element can contact the skin of a user of the hair-cutting device, while at the same time the hair collector is configured so that it does not contact the user's skin. In this way, the hair lifting and guiding function of the guard of the cutting element is not affected, while at the same time allowing collection of cut hairs that would otherwise fly away. This is shown in detail in Figure 9.

[0053] In one example, when the hair collector is connected to the hair-cutting device, the hair collector is configured so that the cutting elements can contact the skin of a user of the hair-cutting device while the hair collector touches the user's skin. In one example, the skin is contacted just above the level of the cutting elements in front of the razor guard. This allows for maximum collection of cut hair that would otherwise fly away, while also improving user comfort.

[0054] According to one example, at least one side wall 42 of the walls of the housing has a structure 50 that forms a plurality of openings. A more detailed example is shown in Figures 3 to 6.

[0055] In one example, the structure is configured to allow hair to pass through a plurality of openings into the cut hair collection chamber. A schematic example of a detailed embodiment is shown in Figure 8.

[0056] According to one example, when the hair collector is connected to the hair-cutting device, the structure is configured to allow hair to pass through the plurality of openings and into the cut hair collection chamber, a representative detailed example of which is shown in Figure 6.

[0057] As an example, hair that is able to pass through the plurality of openings is uncut hair that is then cut by the cutting element.

[0058] According to one example, the structure is configured to inhibit hair from passing through the plurality of openings and exiting the cut hair collection chamber.

[0059] According to one example, the total surface area of ​​the structures at the outer surface 44 of the at least one sidewall is less than the total surface area of ​​the structures at the inner surface 46 of the at least one sidewall. This is further shown, for example, in the detailed embodiment of FIG.

[0060] According to one example, the structure includes a comb-like structure 60 with a plurality of teeth 70. The teeth taper from the outer surface 44 of at least one sidewall to the inner surface 46 of at least one sidewall. This is further illustrated in the detailed example of Figures 3-6 and 8.

[0061] According to one example, the angle of the tooth taper is constant.

[0062] As an example, the angle of the taper varies from the outer surface to the inner surface. Thus, the tooth sidewalls need not be flat, but may be curved and / or curved with flat regions. As an example, the tooth sidewalls can be concave or convex, or can be both convex and concave, or wavy with both convex and concave regions.

[0063] According to one example, the teeth have a triangular cross section.

[0064] For example, triangular teeth have rounded apexes.

[0065] Thus, the outer wall has a rounded apex and the inner wall has a relatively large surface.

[0066] According to one example, the plurality of openings extend in a longitudinal direction of at least one side wall, the longitudinal direction being perpendicular to the plane of the cutting element when the hair collector is connected to the hair-cutting device. This is further shown in the detailed example of Figures 3 to 6 and 9.

[0067] In one example, the plurality of openings may be linear in the longitudinal direction, i.e., straight. In one example, the plurality of openings may be non-linear in the longitudinal direction, i.e., curved rather than linear in the longitudinal direction. Thus, in one example, the openings may have a wave-like shape in the longitudinal direction.

[0068] According to one example, the spatial period of the plurality of openings is configured to be an integer number of the spatial period of the plurality of openings in the cutting element razor guard 120. A more specific example is shown in FIG.

[0069] In one example, the teeth of the structure are pitched relative to the teeth of the razor guard at a ratio of 1:2, although other ratios such as 1:1, 1:3, 1:4, etc. are also contemplated.

[0070] In one example, when the hair collector is connected to the hair-cutting implement, the plurality of openings in the structure are configured to align with an equal number of openings in the plurality of openings in the razor guard.

[0071] According to one example, the first side wall 42a and the second side wall 42b of the plurality of walls each have a structure. The first side wall is on the opposite side of the housing from the second side wall. More detailed examples are shown in Figures 5, 6, and 9.

[0072] As an example, the hair collector is symmetrical about a 180 degree rotation about a central axis.

[0073] This facilitates alignment for connection to both double-sided and single-sided cutting tools while reducing manufacturing costs.

[0074] According to one example, when the hair collector is connected to the hair-cutting device, at least two side walls of the plurality of walls define an outer plane at an outer extent of the hair collector. The hair collector is configured such that when the cutting element contacts the user's skin, the outer surface of the hair collector lies above the surface of the cutting element adjacent the user's skin. Further examples are shown in Figures 6 and 9.

[0075] By way of example, the edge of the hair collector is 1 mm above skin level when the cutting element is in contact with the skin. Other spacings such as 0.5 mm, 0.75 mm, 1.25 mm, 1.5 mm, 1.75 mm, and 2 mm can be used. By way of example, the edge of the hair collector is just above the user's skin level and just in front of the razor guard.

[0076] As an example, when the hair collector is connected to the hair-cutting appliance, the outer plane of the hair collector is substantially parallel to the plane of the cutting element.

[0077] Figure 2 shows an example of a hybrid hair-cutting device 100 having a cutting element 110 and a razor guard 120. The hybrid hair-cutting device is configured for both shaving and trimming. A hair collector 10, as described with reference to Figure 1, is connected to the hybrid hair-cutting device.

[0078] In one example, the hair-cutting device is configured to allow for disconnection of the hair collector.

[0079] However, the connection of the hair collector 10 to the hybrid hair-cutting device can be permanent. Accordingly, FIG. 2 also relates to an example hybrid hair-cutting device 100 having a cutting element 110 and a razor guard 120. The hybrid hair-cutting device is configured for both shaving and trimming. The hybrid hair-cutting device has an integrated hair collector 10a. The hair collector has a housing 20 including a plurality of walls 40. A cut hair collection chamber is formed with the housing walls and the cutting element. The hair collector is configured to allow the cutting element to contact the skin of a user of the hair-cutting device. Reference to hair collector 10a refers to a hair collector integrated with the hair-cutting device, which, although not specifically shown in FIG. 2, has the same characteristics as hair collector 10, except that it is not detachable from the hair-cutting device.

[0080] In one example, the drive system of the cutting element is at least partially located within the cut hair collection chamber.

[0081] In one example, the hair-cutting tool has a main housing, and the hair collector is disposed at least partially around the cutting element between the cutting element and the main housing.

[0082] As an example, the hair collector is configured such that the cutting element can contact the skin of a user of the hair-cutting device, while at the same time the hair collector does not contact the skin of the user.

[0083] In one example, the hair collector is configured such that the cutting element can contact the skin of a user of the hair-cutting device while the hair collector is in contact with the user's skin, in one example, the skin is contacted just above the level of the cutting element in front of the razor guard.

[0084] In one example, at least one side wall 42 of the walls of the housing has a structure 50 that forms a plurality of openings.

[0085] In one example, the structure is configured to allow hair to pass through a plurality of openings into the cut hair collection chamber.

[0086] In one example, the structure is configured to allow hair to pass through a plurality of openings into the cut hair collection chamber.

[0087] As an example, hair that is able to pass through the plurality of openings is uncut hair that is then cut by the cutting element.

[0088] In one example, the structure is configured to inhibit hair from passing through the plurality of openings and exiting the cut hair collection chamber.

[0089] In one example, the total surface area of ​​the structures on the outer surface 44 of the at least one sidewall is less than the total surface area of ​​the structures on the inner surface 46 of the at least one sidewall.

[0090] In one example, the structure includes a comb-like structure 60 with a plurality of teeth 70. The teeth taper from an outer surface 44 of at least one sidewall to an inner surface 46 of at least one sidewall.

[0091] In one example, the angle of the tooth taper is constant.

[0092] In one example, the teeth have a triangular cross section.

[0093] For example, triangular teeth have rounded apexes.

[0094] In one example, the plurality of openings extend longitudinally of the at least one sidewall, the longitudinal direction being perpendicular to the plane of the cutting element.

[0095] In one example, the spatial period of the plurality of openings is configured to be an integer number of times the spatial period of the plurality of openings in the razor guard 120 of the cutting element.

[0096] As an example, the teeth of the structure are pitched at a 1:2 ratio to the teeth of the razor guard.

[0097] In one example, the plurality of openings in the structure are configured to align with an equal number of the plurality of openings in the razor guard.

[0098] In one example, the first side wall 42a and the second side wall 42b of the plurality of walls each have a structure. The first side wall is on the opposite side of the housing from the second side wall.

[0099] As an example, the hair collector is symmetrical about a 180 degree rotation about a central axis.

[0100] In one example, at least two side walls of the plurality of walls define an outer plane at an outer extent of the hair collector, and the hair collector is configured such that when the cutting element contacts the user's skin, the outer surface of the hair collector lies above the surface of the cutting element adjacent the user's skin.

[0101] By way of example, the edge of the hair collector is 1 mm above skin level when the cutting element is in contact with the skin. Other spacings such as 0.5 mm, 0.75 mm, 1.25 mm, 1.5 mm, 1.75 mm, and 2 mm can be utilized. By way of example, the edge of the hair collector is just above the user's skin level and just in front of the razor guard.

[0102] As an example, when the hair collector is connected to the hair-cutting appliance, the outer plane of the hair collector is substantially parallel to the plane of the cutting element.

[0103] The figures also relate to a method of collecting hair from a hair-cutting device 100 having a cutting element 110. The method comprises the step of connecting a hair collector 10 to a hair-cutting device. The hair collector comprises a housing 20 and an attachment portion 30. The housing has a plurality of walls 40. The attachment portion attaches the hair collector to the hair-cutting device. Collection of cut hair is provided through the formation of a cut hair collection chamber. The cut hair collection chamber comprises a plurality of walls of the housing and the cutting element. The hair collector is configured such that the cutting element can contact the skin of a user of the hair-cutting device.

[0104] In one example, the drive system of the cutting element is at least partially located within the cut hair collection chamber.

[0105] In one example, the attachment portion attaches a hair collector to the cutting element.

[0106] In one example, the attachment part releasably attaches the hair collector to the hair-cutting device.

[0107] In one example, a wall 48 of the plurality of walls has an opening into which a connecting portion of a cutting assembly of a hair-cutting tool can be inserted. The cutting assembly comprises a cutting element.

[0108] In one example, the hair-cutting tool has a main housing, and the hair collector is disposed at least partially around the cutting element between the cutting element and the main housing.

[0109] In one example, the hair-cutting device is a hybrid hair-cutting device configured for both shaving and trimming.

[0110] As an example, the cutting element may contact the skin of a user of the hair-cutting apparatus, while the hair collector does not contact the skin of the user.

[0111] In one example, the cutting element can contact the skin of a user of the hair-cutting implement while the hair collector contacts the skin of the user, in one example, the skin is contacted just above the level of the cutting element in front of the razor guard.

[0112] In one example, at least one side wall 42 of the walls of the housing has a structure 50 that forms a plurality of openings.

[0113] As an example, the structure allows hair to pass through a plurality of openings into the cut hair collection chamber.

[0114] As an example, hair that is able to pass through the plurality of openings is uncut hair that is then cut by the cutting element.

[0115] In one example, the structure inhibits hair from passing through the plurality of openings and exiting the cut hair collection chamber.

[0116] In one example, the total surface area of ​​the structures on the outer surface 44 of the at least one sidewall is less than the total surface area of ​​the structures on the inner surface 46 of the at least one sidewall.

[0117] In one example, the structure includes a comb-like structure 60 with a plurality of teeth 70. The teeth taper from an outer surface 44 of at least one sidewall to an inner surface 46 of at least one sidewall.

[0118] In one example, the angle of the tooth taper is constant.

[0119] In one example, the teeth have a triangular cross section.

[0120] In one example, the plurality of openings extend longitudinally of the at least one sidewall, the longitudinal direction being perpendicular to the plane of the cutting element.

[0121] In one example, the spatial period of the plurality of openings is configured to be an integer number of times the spatial period of the plurality of openings in the razor guard 120 of the cutting element.

[0122] In one example, the teeth of the structure are pitched relative to the teeth of the razor guard at a ratio of 1:2, although other ratios such as 1:1, 1:3, 1:4, etc. are also contemplated.

[0123] In one example, the plurality of openings in the structure are aligned with an equal number of the plurality of openings in the razor guard.

[0124] In one example, of the multiple walls, a first side wall 42a and a second side wall 42b each have a structure, and the first side wall is on the opposite side of the housing from the second side wall.

[0125] As an example, the hair collector is symmetrical about a 180 degree rotation about a central axis.

[0126] In one example, at least two side walls of the plurality of walls define an outer plane at an outer extent of the hair collector, and the hair collector is configured such that when the cutting element contacts the user's skin, the outer surface of the hair collector lies above the surface of the cutting element adjacent the user's skin.

[0127] By way of example, the edge of the hair collector is 1 mm above skin level when the cutting element is in contact with the skin. Other spacings such as 0.5 mm, 0.75 mm, 1.25 mm, 1.5 mm, 1.75 mm, and 2 mm can be utilized. By way of example, the edge of the hair collector is just above the user's skin level and just in front of the razor guard.

[0128] As an example, when the hair collector is connected to the hair-cutting appliance, the outer plane of the hair collector is substantially parallel to the plane of the cutting element.

[0129] A hair collector for a hair-cutting device having a cutting element, and a hybrid hair-cutting device including such a hair collector, will be further described below with reference to specific embodiments shown in Figures 3-9.

[0130] As shown in FIG. 3, a space or chamber for collecting cut hair particles is provided between the hybrid hair-cutting device housing (both not shown) and the cutting element 110 of the hybrid hair-cutting device. This is achieved by placing a (double-sided) hair collector 10, with a sidewall 42 including a comb-like structure 60 with multiple teeth 70, over the cutting element, as shown in image sections 1, 2, and 3 of FIG. 3. The cut hair collection chamber is formed by the hair collector wall 40 and the cutting element. The hair collector in this example does not contact the skin to allow optimal hair capture by the cutting element, allowing (long) hair to easily move through the opening and not affect the function of the razor guard 120. Further illustrating with reference to FIG. 9, because the hair collector teeth do not act at skin level but are located above the cutting element, the lifting and cutting performance of the hybrid cutting device is not affected. In the specific embodiment shown in FIG. 9, the hair collector teeth are 1 mm above skin level when the cutting element contacts the skin, and are located just in front of the razor guard. In this way, a large amount of cut hair is collected and not scattered, and the hair collector can be simply placed on the cutting assembly. However, in specific embodiments, the teeth of the hair collector may contact the skin at the same time that the cutting element contacts the skin.

[0131] Referring to FIG. 3, the hair collector forms a collection chamber together with the cutting element, essentially a cap that provides a removable compartment for collecting cut hair. A securing and alignment system allows the hair collector to be guided into position and locked onto the cutting assembly. The hair collector has a filtering inlet system that allows hair, including long hairs, to enter the system, be cut, and be retained within the formed hair collection chamber. Each tooth on the opposing wall of the hair collector is a comb-like element that is shaped to guide hair when viewed in the direction of hair advance toward the cutting direction and to block hair debris when viewed in the opposite direction. This can be achieved, for example, by having a triangular shape with its top or apex pointing away from the cutting element.

[0132] As shown in FIG. 4, the hair collector can be easily placed on the cutting assembly because the top wall 48 has an opening that locks the hair collector onto the cutting assembly. As shown in FIG. 5, a set of snap hooks allows the hair collector to be secured to the cutting assembly, for example, as shown in FIG. 5, two opposing side walls 42a and 42b have a comb-like structure 60 with teeth 70. The hair collector can be made by one-piece injection molding. Furthermore, as shown in FIG. 5, the hair collector can be made into a more open configuration, which allows the hair collector to operate with hair cutting tools having a specific type of handle that operates in the open configuration. However, this open configuration still provides a hair collection chamber from the walls of the hair collector and the cutting element, and can operate with specific types of hair cutting tools, such as different handles and different control shapes.

[0133] The hair filtering and collection system is shown in detail in Figures 6 and 7. A semi-open filtering system is provided, allowing hair to pass through the hair filter system and enter the hair collection chamber, but blocking hair from exiting the collection chamber after being cut. The hair collector wall is positioned directly above the cutting element, and the teeth of the comb structure on the wall do not interfere with the razor guard's ability to lift hair. The size of the grooves between the teeth is optimized to allow hair entry across the entire front surface while largely blocking hair from exiting the inner hair collection chamber. The teeth on the side walls of the hair collector act as a funnel, facilitating hair inward movement and preventing it from exiting. To optimize this effect, the teeth have a small outer (front) surface and a large inner (back) surface. The size and shape of the outer tooth surfaces are designed to function as described, but in this specific example, are designed to be compatible with injection molding manufacturing. The inner surface dimensions are designed for penetration performance, taking into account the rate at which hair enters the system. The teeth are shaped to gradually influence the direction of the hair. A fixed angle allows for a continuous reaction force on the moving hair, moving it towards the exit, but other shapes are also practical. The smaller the angle, the less hair is pushed out of the system.

[0134] 8 shows a plan view of an exemplary shape of the teeth on one sidewall of the hair collector, where the teeth start on an outer plane 44 and diverge toward an inner plane 46. In this example, the teeth are pitched at a 1:2 ratio with the teeth on the razor guard, although other ratios are possible.
