Definitions

• This invention relates generally to power toothbrushes and more specifically to power toothbrushes having multiple bristle motions, with different drive signals for different motions.
• power toothbrushes include multiple brushing modes or routines, typically focusing on general dental care needs, such as soft or gentle brushing, or oral massage, gum care/stimulation, among others. These routines have historically been limited to oral care objectives. In some applications, power toothbrushes are driven to produce complex motions, such as a combination of both sweeping or rotational motion and an axial motion.
• oral care is a part of a morning or evening routine, which includes in the evening eventually falling asleep and in the morning waking up.
• a power toothbrush comprises: a handle portion; a brushhead having a set of bristles at the distal end thereof; a first drive signal source producing a first bristle motion having an effective cleansing action for a user's teeth; a second drive signal source producing a second bristle motion with an audible sound which produces a cognitive stimulating or relaxing effect, wherein the first and second drive signals are combined to produce a combined drive signal; and a drive system within the handle portion responsive to the combined drive signal to produce a multiple bristle motion, producing a cleansing effect and audible sounds which produce a cognitive effect.
• FIGS 1A and IB show simplified diagrams of power toothbrushes having multi-motions of the brushheads.
• Figure 2 is a simplified block diagram of the brushhead driving system incorporated in the power toothbrush of the present invention.
• FIG 1A is a simplified view of a power toothbrush, shown generally at 10.
• the power toothbrush includes a handle or body portion 12 within which is positioned a drive system 14 and a power source 16, which can be, for instance, a battery, which may be rechargeable.
• the drive system drives or extends through a neck portion 18 of the toothbrush which extends from the handle 12.
• a brushhead 20 At the distal end of the neck 18 is a brushhead 20.
• the brushhead includes a set of bristles 22.
• the power toothbrush 10 is driven to produce multiple motions of the brushhead and bristles.
• a multiple motion brushhead is shown in Figure 1 A, in which the brushhead and the bristles move in a sweeping motion 23 (back and forth) as well as an axial motion (25) longitudinally of the toothbrush.
• a brushhead 26 and bristles move with both a sweeping motion 27 and a tapping motion 28, perpendicular to the longitudinal axis of the toothbrush.
• Other multiple motions are possible.
• a first, primary bristle motion of the brushhead/bristles has characteristics which produce effective cleaning.
• This could be a sweeping motion, which is disclosed in U.S. Patent No. 5,378, 153, the contents of which are hereby incorporated by reference.
• the frequency of motion is within the range of 40 Hz-500 Hz, with an amplitude of 0.5-6 mm and a bristle tip velocity of 1.5-2 meters per second. In one specific embodiment, the frequency is 250-270Hz, with an amplitude of 2.5 mm.
• Other arrangements can be utilized, as long as the bristle motion produces an effective cleansing effect.
• Another bristle motion referred to as a secondary motion, separate from the first bristle motion, is produced by another, separate drive signal comprising various tones, rhythms, music or other sounds, which can be heard during use of the toothbrush.
• the variable tones or audible sounds produced by action of the drive system with the two drive signals acting on the brushhead/bristles produce either cognitive stimulation or cognitive relaxation.
• the secondary bristle motion producing the cognitive effect is independent of the primary bristle motion and does not negatively affect the teeth-cleaning action of the primary bristle motion.
• the drive signal/signals producing the cognitive-affecting secondary bristle motion can have various patterns.
• One pattern is an increasing frequency to produce a cognitive stimulation or wakefulness sound, audible to the user, while another pattern could be a gradually decreasing frequency to produce a cognitive relaxation effect.
• the audible sounds will be in the frequency range of 12-20,000 Hz, with a preferred range of 110- 3500 Hz.
• the sounds can change regularly, at specific times in a two-minute brushing event, e.g. every 30 seconds.
• the sounds could be complex over the brushing period, producing either stimulating sounds/music for cognitive stimulation or wakefulness, or more soothing music or sounds to produce a cognitive relaxation or restfulness.
• the sounds could be other restful sounds, such as the sounds of water and surf, or stimulating sounds, such as various bird sounds or even stormy weather sounds.
• the secondary bristle motions produced by action of the drive system will act like an audio speaker, in response to the associated drive signals.
• the primary bristle motion produces the desired effective cleaning. Both motions are driven at amplitudes such that the combined motions produce a bristle tip velocity greater than 1.5 meters per second and a bristle tip amplitude of 0.5-6 mm, preferably 2-3 mm, for the effective cleaning.
• the sound produced by action of the appliance with the two drive signals producing primary and secondary bristle motions will feel like an increase in intensity of bristle action from the start of the brushing period to the end thereof, producing a stimulating effect, while the sounds will feel like a decrease in intensity from start of the brushing period to finish thereof, producing a cognitive/mental relaxation effect.
• FIG 2 shows a simplified view of the drive signal system described above.
• the drive signal No. 1 referred to as a primary drive signal, is shown at 30, and produces the teeth cleaning effect at the desired effective frequency.
• Drive signal No. 2 referred to as a secondary drive signal and referenced at 32, is the source of the variable sound, music, etc. which results in the cognitive stimulation/relaxation effect.
• These two drive signals are combined to form a combined drive signal for the system driver referred to at 34, which drives the brushhead 36 with the multiple bristle motion, shown for example in Figures 1A and IB, or other combinations of motions.
• the two motions in two or more directions, are driven at such amplitudes that the combined motion produces a bristle tip velocity greater than 1.5 meters per second and an amplitude of between 0.5 mm and 6 mm.
• the audible sound, produced from the appliance by this arrangement results in a cognitive effect, either relaxing or stimulating.
• a new toothbrush which has multiple bristle motions, in which one bristle motion produces effective teeth cleaning, while the combined action of another bristle motion produces audible sounds which result in a cognitive stimulating or relaxing effect.
