TECHNICAL FIELD
[0001] The present disclosure relates to a hairbrush for attachment to a hair styling appliance. BACKGROUND
[0002] A hairbrush tool can be attached to the air outlet of a hair styling appliance, such as a hairdryer or a hot air styler, and used to deliver air flow to the hair while combing the hair. SUMMARY
[0003] A first aspect of the present disclosure provides a hairbrush for attachment to an air outlet of a hair styling appliance, comprising: an elongate cylindrical body comprising an air inlet at an end of the body for receiving air flow from the hair styling appliance, a plurality of openings through a side wall, and an air flow path between the air inlet and the plurality of openings, a plurality of bristles anchored inside the cylindrical body and protruding outwardly through the openings, wherein the diameter of the cylindrical body is in the range 50mm to 60mm, and the bristles protrude outwardly through the openings to an average distance in the range 9mm to 13mm from an outer surface of the cylindrical body.
[0004] The inventors have found that the diameter and length of the cylindrical body and the length of the bristles are closely related to the tension applied by the hairbrush to the hair, and therefore to the characteristics of the style applied to the hair and the user experience of the hairbrush. Indeed, it has been found that these parameters of the brush are interrelated, for example because the tension applied by each bristle to the hair is a function of the length of the bristle and the diameter of the cylindrical body. For example, it has been found that a cylindrical body of larger diameter, which can be preferred to impart certain hair styles, such as loose curls, can tend to have the effect of contacting hair of greater length, and therefore the tension applied by the hairbrush to the hair can be relatively greater than for a cylindrical body of smaller diameter, for a given bristle length and density.
[0005] In particular, it has been determined that for a cylindrical body having a diameter in the range 50mm to 60mm, which can be suitable for imparting a relatively loose curl to the styled hair, it is desirable for the bristles to have an exposed length in the range 9mm to 13mm, i.e. the radial distance they protrude outwardly from the outer cylindrical surface of the cylindrical body.
[0006] The bristles can protrude outwardly through the openings to an average distance in the range 10mm to 12mm from the outer surface.
[0007] The bristles can protrude outwardly through the openings to an average distance of 10.5mm from the outer surface.
[0008] The plurality of bristles can be arranged to have an average density in the range 360 to 400 bristle protrusions per 10mm of length of the cylindrical body along the length of the cylindrical body.
[0009] The plurality of bristles can be arranged to have an average density in the range of 370 to 390 bristle protrusions per 10 millimetres of length of the cylindrical body.
[0010] The length of the cylindrical body can be in the range of 80 to 90 millimetres.
[0011] The length of the cylindrical body can be in the range of 83 to 87 millimetres.
[0012] The diameter of the cylindrical body can be in the range of 53 to 57 millimetres.
[0013] A second aspect of the present disclosure provides a hair styling apparatus comprising: a hair styling appliance comprising a fan for generating an airflow and an air outlet for discharging the airflow; and a hairbrush according to any one of the preceding claims releasably attachable to the hair styling appliance such that, when attached, the air inlet of the hairbrush is fluidly coupled to the air outlet of the hair styling appliance.

[0024] In Figure 1 and Figure 2 a hair styling device 101 embodying aspects of the present disclosure is shown schematically. The device comprises a hair styling appliance 102 and a hairbrush 103 attachable to the hair styling appliance. The hair styling appliance 102 is configured to be handheld by a user and for use in styling the hair of a person using an airflow.
[0025] The hair styling appliance 102 comprises a cylindrical body 104 which externally defines a handle portion 105 for gripping in a user’s hand and which internally defines a void for housing a motor-driven fan 106. The motor-driven fan 106 is depicted as being visible in Figure 1 and Figure 2 but in practice can be obscured from view by the opaque body 104. The body 104 defines a plurality of air inlets 107 at a lower end and an air outlet 108 at an upper end. The motor-driven fan 106 is operable to draw in air through the air inlets 107 and to expel an airflow via the air outlet 108.
[0026] The hair styling appliance 102 may, for example, comprise a heater located in the airflow path to heat air flowing therethrough, and can comprise user-operable controls mounted on the body 104 for controlling operation of the motor-driven fan 106 and / or the heater.
[0027] The hairbrush 103 comprises an elongate cylindrical body 109 and a plurality of bristles 111. The body 109 comprises an air inlet 110 at an end of the body and a plurality of openings 113 in a cylindrical side wall of the body 109. An end of the cylindrical body 109 opposite the air inlet 110 is closed. The body 109 comprises a bayonet feature 112 arranged around a periphery of the air inlet 110 which cooperates with a corresponding feature of the body 104 of the hair styling appliance 102, thereby to releasably attach the hairbrush 103 to the hair styling appliance 102. In the attached state, as shown in Figure 1 the air inlet 110 of the hairbrush 103 is fluidly coupled to the air outlet 108 of the hair styling appliance 102 to receive the airflow from the hair styling appliance.
[0028] In use, a user can pull the bristles 111 of the hairbrush 103 through the hair whilst the airflow generated by the hair styling appliance 102 is expelled through the openings 113. The tension exerted on the hair by the bristles 111 and the airflow (which can be a heated airflow) can therefore be used to style the hair.
[0029] Referring next to Figures 3 to 9 the cylindrical body 109 of the hairbrush 103 is hollow and defines an airflow path 901 for carrying the airflow between the air inlet 110 and the plurality of openings 113.
[0030] The cylindrical body 109 is relatively rigid and can be formed from a rigid plastic or metal. The cylindrical body 109 includes a rigid stem 902 fixed within to extend along the diametric centre of the cylindrical body 109. The diameter “D1” of the cylinder 109 is in the range 50-60mm, for example approximately 55mm.
[0031] The openings 113 each extend through the sidewall of the body 109 to exhaust airflow from within the airflow path 901. The plurality of openings 113 are distributed across the entire circumference of the cylindrical body 109 and along a substantial axial length of the cylindrical body 109, thereby diffusing airflow onto the user’s hair. In examples, the average diameter of the openings is in the range 1-4mm, for example in the range 2-3mm.
[0032] The bristles 111 are anchored to the stem 902 and arranged to extend radially outwardly from the stem 902 to protrude outwardly from the cylindrical body 109 through the openings 113. In this example, the bristles 111 are double-ended, such that a single bristle 111 forms a first bristle protrusion 903 protruding from a first opening in a first radial direction and a second bristle protrusion 904 protruding from a second opening in a second radial direction (e.g. a substantially diametrically opposite radial direction). Thus, in this example, a single bristle structure can form two bristle protrusions protruding from the cylindrical body 109. In other examples, the bristles 111 can be single-ended and form only a single bristle protrusion protruding from only a single opening. The bristles 111 are relatively flexible and can be formed from a flexible plastic such as nylon or a natural material such as animal hair.
[0033] The inventors have found that the diameter and length of the cylindrical body 109, the length of the bristles 111 and the density of the bristles 111 are closely related to the tension applied to the hair by the hairbrush and thus to the characteristics of the style applied to the hair and the user experience of the hairbrush. Indeed, it has been found that these parameters of the brush are interrelated, for example because the tension applied to the hair by each bristle is a function of the length of the bristle and the diameter of the cylindrical body. For example, it has been found that a larger diameter cylindrical body (which can be preferable to impart certain hair styles, for example loose curls) can tend to have the effect of contacting hair of a greater length and thus, for a given bristle length and density, the tension applied to the hair by the hairbrush can be relatively greater than a smaller diameter cylindrical body. Thus, in order to maintain a desired hair tension, for styling and / or user experience reasons, it can be desirable to, for example, reduce the bristle length and / or bristle density if the diameter of the cylindrical body is increased.
[0034] In particular, it has been determined that for a cylindrical body 109 having a diameter in the range of 50 to 60 millimetres, this diameter range can be suitable for imparting a relatively loose curl to the styled hair, the bristles 111 are preferably best having an exposed length in the range of 9 to 13 millimetres, i.e. the radial distance "D2" by which they protrude outwardly from the outer cylindrical surface of the cylindrical body. It has also been found that it is desirable for the plurality of bristles 111 to be sufficiently numerous so as to have an average density of 360 to 400 bristle protrusions per 10 millimetres of axial length of the cylindrical body 109. In the case of single-ended bristles, this can mean 360 to 400 bristles. In the case of double-ended bristles, this can mean 180 to 200 bristles. It has been determined that these parameters can advantageously provide a desirable balance of cylindrical body diameter, indicative of tightness of curl imparted to the hair, and tension applied to the hair, in relation to user experience and hair style retention.
[0035] In particular, it has been found that a cylindrical body diameter in the range of 53 to 57 millimetres can provide a desirable tightness of curl. And it has been found that a cylindrical body length in the range of 80 to 90 millimetres, for example in the range of 83 to 87 millimetres, an average bristle protrusion length in the range of 10 to 12 millimetres, for example approximately 10.5 millimetres, and an average bristle density in the range of 370 to 390 bristle protrusions per 10 millimetres of axial length of the cylindrical body 109, can enable a desirable high tension characteristic to be applied.
