Abstract

Vibrating hair grooming device comprising a grip means (1) and a bristle-bearing head (2), the device comprising a linear motor (4)

Description

HAIR GROOMING DEVICE
The present invention relates to a grooming implement with a linear motor.
Despite the prior art there remains a need for improved detangling devices.
Accordingly, the present invention relates to a grooming implement according to claim 1.
Vibrating hair grooming device comprising a grip means and a bristle-bearing head, the device comprising a linear motor. The linear motor is any motor which effects vibration by vibrating reciprocally along a fixed axis. This is in contrast to a motor which rotates a drive shaft about the drive shaft's axis.
Preferably, the handle houses the motor. Preferably the handle comprises a rigid material and the rigid material provides a fixed housing for the motor such that the motor itself does not move during use.
Housing the motor in the handle provides the best weight distribution during use for the brush according to the invention .
Preferably, the motor is disposed such that it vibrates reciprocally along an axis which is parallel to the general longitudinal axis of the hair brush, i.e. runs centrally along the hairbrush. This is so that the head vibrates in a plane parallel to the scalp surface during use and does not vibrate in and out of a plane which is parallel to the scalp and so injure the scalp during use.
Preferably, the handle comprises an inner section and an outer section. Preferably, the outer section partially or wholly surrounds the inner section for at least 30% of the length of the outer section.
Preferably, the outer section is disposed such that the user is not in contact with the inner portion during use. This is to reduce the vibration from the motor to the hands during use. Preferably, the inner section is rigidly connected to the head such that vibration from the motor is effectively communicated to the head during use. In such an embodiment the inner part and the outer part are preferably connected to each other by a damper to reduce vibration in the handle during use.
Preferably, the outer section comprises a grip.
Preferably, the inner section fits inside the outer section such that during use, when the inner section is vibrating, the inner section slides axially within the outer section. Preferably, the clearance between the inner section and outer section is less than 0.2 mm, more preferably from 0.05 to 0.15 mm.
Preferably, the inner section is oval in transverse cross section. This improves the integrity of the handle during use .
Suitable damping means include a layer of resilient material between the handle and the head. Preferred resilient materials include sprung steel, elastomer and rubber. Preferred damper means are resilient bellows and compressible washers.
The linear motor effects axial vibration of the head. By axial vibration of the head means that the head is moved such that the bristles are moved side to side on the brush head. Preferably this movement is also towards and away from the grip while remaining in substantially the same plane. Vibrating bristles which move in and out of their fixed plane create a negative consumer experience during use since they move towards and away from the scalp at high frequency. Vibrating bristles which vibrate in a plane which is parallel to the scalp during use and orthogonal to the hair length direction during use provide the best detangling.
The head according to the invention comprises bristles for brushing and detangling the hair. Preferably, the bristles are fixed to a brushing head which is either planar, in which case the bristles will project substantially in the same direction or that it is a cylinder in which case the head comprises radially projecting bristles.
Preferably, the head is detachable from the remainder of the brush. This allows the user to use different heads for different purposes. Different heads might include a cylindrical head, a planar head, a convex head, a massaging head or a head with multifunctional bristles.
Preferably, the head is hermetically sealed to the handle. This can be done by way of bellows, preferably resilient bellows and keeps the motor water-tight during use.
Preferably, the hermetic seal is a diaphragm attached to the handle and the head.
Preferably, the brush according to the invention comprises a power source. This power source may be a battery, more preferably a rechargeable battery. Alternatively, the brush according to the invention will comprise a mains connector for connecting to the mains in order to power the motor.
Preferably, the motor vibrates at from 10 to 200 Hz, preferably from 20 to 100 Hz. This provides the optimum detangling frequency during use.
Embodiments of the invention will now be described with reference to the following non-limiting drawings in which:
Figure 1 is a perspective view of a brush;
Figure 2 is a side view of the brush according to Figure 1 with the handle in section; and
Figure 3 is a side view of an alternative brush with the handle in section. In detail Figure 1 shows a hair brush comprising a handle 1 and a head 2. The head has bristles 3 attached thereto for brushing the hair.
The handle is connected to the head part by way of bellows 6 at a head end of the handle and a distal end of the handle. The handle houses a power source 5 and a motor 4 for effecting linear vibration of the brush head 2.
Figure 2 shows a hair brush according to Figure 1 but with the handle in section along a central vertical plane. Shown are the battery power source 5, drive control 11 for controlling the output of the motor and the motor 4. The motor is fixed by a clamp 12 so that it does not move relative to its mounting. The handle body 13 is made from rigid material such that as much vibrational energy as possible is transmitted to the head 2.
The grip part 9 is connected to the rest of the brush by way of resilient bellows 6 at either end of the grip part 9.
When the motor vibrates its housing and therefore the head the handle is protected from vibration by the dampers 6. The brush is activated by an on switch 10.
Figure 3 shows an alternative design where the grip part 9 is more substantial and partially surrounds the housing for the motor 4 in the handle. The vibrations from the motor 4 generate vibration in the head 2. The vibration in the grip part 9 are reduced due to dampers 14 between the grip part 9 and the handle core 13. The brush is activated by an on switch 10.
