Definitions

  • This invention relates generally to hair brushes, including power hair brushes, and more particularly concerns such a power hair brush which is adapted for detangling hair.
  • Hair tangles can result from many factors or causes. They occur when hair strands do not lie neatly against each other, but rather are mixed up. Hair tangles can occur, for example, from a lack of consistent combing, by piling hair when it is being washed, from the effects of wind and from sleeping without a hairnet/protector. The extent and condition of hair tangles can also vary depending upon the texture and length of the hair, as well as the fullness of the hair. Whatever the cause and extent, however, it is important to detangle the hair to maintain its overall health and appearance. Detangling, however, can be a time-consuming and in some cases painful experience. Detangling hair products can help, but are typically not the complete or best solution for the many types of tangles.
  • a brush appliance for detangling hair comprises: an appliance body; a brushhead mounted to the appliance body; a motor for oscillating the brushhead at a selected frequency and amplitude; a system for recognizing a hair tangle as the brushhead is moved through the hair; and a control system for changing the driving of the brushhead and/or providing a detangling solution to the brushhead so as to detangle hair as the brushhead encounters the tangle.
  • a method for detangling hair using a power hair brush comprises the steps of: Oscillating a brushhead portion of the hair brush at a selected frequency and amplitude; recognizing a hair tangle as the brushhead is moved through the hair; and changing driving of the brushhead and/or providing a detangling solution to the brushhead so as to detangle the hair as the brushhead encounters the tangle.
  • Figure 1 is a structural block diagram of a detangling hair brush in accordance with the present invention.
  • Figure 2 is a functional diagram of the operation of the appliance of Figure 1.
  • Figure 3A is a simplified diagram showing the position of the appliance prior to detangling.
  • Figure 3B is a simplified diagram showing the position of the appliance during detangling.
  • Figure 3C is a simplified diagram showing the detangled hair. Best Mode for Carrying Out the Invention
  • FIG. 1 shows the appliance in schematic block form at 10.
  • the appliance includes a body 12 with a removable hair brush 14.
  • the hair brush itself is conventional and can have a variety of bristle arrangements and configurations.
  • the brushhead is driven in an oscillating manner by a motor 16 which is controlled by a drive unit 18.
  • the motor and drive unit can take a variety arrangements. One such arrangement, among many, is shown in US Patent No. 7,157,816.
  • the drive unit is typically powered by a rechargeable battery 20, which could be by solar charging.
  • the appliance includes one or more power sources.
  • Non-limiting examples of power sources include one or more button cells, chemical battery cells, a fuel cell, secondary cells, lithium ion cells, micro-electric patches, nickel metal hydride cells, silver-zinc cells, capacitors, super-capacitors, thin film secondary cells, ultra-capacitors, zinc-air cells, or the like.
  • Further non-limiting examples of power sources include one or more generators (e.g., electrical generators, thermo energy-to-electrical energy generators, mechanical-energy-to-electrical energy generators, micro- generators, nano-generators, or the like) such as, for example, thermoelectric generators, piezoelectric generators, electromechanical generators, or the like.
  • the power source includes one or more micro-batteries, printed micro-batteries, thin film batteries, fuel cells (e.g., biofuel cells, chemical fuel cells etc.), or the like, including replaceable alkaline cells.
  • the appliance is controlled by an on/off switch 22.
  • the brushhead moves at a frequency in the range of 70-1 15 Hz, although this can be varied.
  • the preferred amplitude is 10-19° peak-to-peak, with a duty cycle of approximately 40%, although these values again can be varied.
  • the load applied to the motor by combing untangled hair is determined. This produces a learned baseline for the detangling operation. This load value, in terms of frequency and amplitude, is stored in the control unit processor.
  • the brush identifies a tangle as the brushes move through the hair by measuring a change in the load condition of the motor, relative to the baseline load. This change in load will typically modify the action/behavior of the system.
  • the measurement can be done by various arrangements.
  • One preferred arrangement to measure the change in amplitude of the armature portion or end effecter of the motor, as shown, at 24 in Figure 1 such as by an optical encoder.
  • the optical encoder 24 can typically be internal of the housing of the appliance, although it can also be external. It measures amplitude by determining whether an infrared LED light or lights are obscured or not obscured, depending on the specific arrangement used.
  • the change in amplitude must be verified for a particular number of cycles of operation, usually more than one, typically up to five, although a one cycle change can be used.
  • optical encoder is one preferred arrangement
  • other motor amplitude sensors can be used, including a Hall effect sensor for determining the change of amplitude of the motor armature.
  • Other possible arrangements include a magnetic switch which is actuated as the armature approaches the position of the switch.
  • a physical contact switch could also be used.
  • the information from amplitude sensor 24 is applied to the control unit (processor) 28 which is programmed to recognize a tangle, for instance when the motor armature amplitude decreases a preselected amount.
  • This amount can vary, but should be sufficient to reliably indicate a tangle. For example, this could be a decrease in amplitude of 10-20%.
  • the processor will then adjust the drive unit 18 to address the tangle.
  • This can be done in various ways.
  • One method would be to change the motor frequency. This change of frequency will continue until the hair is detangled, or alternatively the change in frequency could be for a burst of 5-10 cycles, sometimes referred to as a slew of frequency, either an increase or decrease.
  • the change in frequency would be to correspond to the new system load and increase amplitude.
  • the change in frequency could be a value in the range between + 50 Hz from the original frequency.
  • the adjustment could be made by a change in duty cycle, in the range of a + 25% change in the original duty cycle.
  • detangling lubricant could be released from a dispenser 36 to the brushhead 14.
  • the change in duty cycle or frequency can be combined and also used in combination with the release of lubricant.
  • FIG. 2 A functional flow chart is shown in Figure 2, based on a change in motor load and subsequent change in motor action/behavior.
  • the appliance is turned on, as shown in block 34, and is used to comb hair in a conventional manner, as shown in block 36A.
  • the normal motor load is determined and stored during combing of untangled hair, block 37.
  • the appliance is used to comb the hair and if the appliance does not encounter a tangle, block 38, combing is continued, until at 36B it is completed. At that point, the appliance is turned off at 40. If a tangle in encountered, at 41, the brush behavior will change, usually the brush amplitude will decrease, due to the increased load, as shown in block 42.
  • a sensor such as an optical encoder, will sense the decrease in amplitude as indicated in block 44.
  • the processor will adjust the drive wave form in some manner such as frequency, voltage, pulse width, etc., as shown at block 46, and/or may in addition cause the appliance to release a detangling fluid through the brush, as shown at block 48.
  • Figure 3 A shows appliance 52, with an oscillating brushhead 54, approaching a tangle 56 in the hair 5.
  • Figure 3B shows the appliance operating on the tangle, by recognizing a change of amplitude, for example, as the tangle is encountered and then changing the action of the motor and hence the brushhead.
  • the tangle is released, as shown at block 58 and in Figure 3C.
  • the brush amplitude will change (typically increase) due to a change (decrease) in load, as shown at block 60.
  • This change in amplitude will be detected, as represented by block 62.
  • the processor will recognize the change in amplitude and will reset the motor drive to the original wave form, as shown in block 64. Further, any release of lubricant will be terminated.
  • the flow chart of Figure 2 represents the function steps each time a tangle is encountered by the appliance.
