In one embodiment, the hair treatment system intelligently treats or diagnoses hair and scalp by region. In one embodiment, a proximity sensor such as a camera or infrared (IR) or both camera and infrared sensor in conjunction with a contact sensor uses approximate distance and locality and modifies spraying or diagnostic products to the scalp along the length of the hair. It is used to generate commands that

In one embodiment, the hair treatment system not only distinguishes the scalp from hair and air, but also facilitates pattern application and treatment dosage (eg, root to hair tip).

In one embodiment, the hair treatment system controls the flow or direction of scalp and hair treatment to minimize debris and inhalable mist.

In one embodiment, the hair treatment system includes a scalp contact sensor, for example an open or short detector on the bristle tips of a brush or comb or a dielectric sensor, whether the hair treatment system is in close contact with the scalp or hair roots. decide

In one embodiment, the overhead position (top vs side) is additionally calculated using an accelerometer. A camera and/or IR sensor determines how far the device is from the scalp, whether it is touching the hair, or whether it has reached the ends of the hair. Different types of product are sprayed (i.e. via nozzles or spray valves) and different types of LEDs are illuminated according to different areas of the hair or scalp (i.e. Red vs UV).

In one embodiment, it is an advantage of the present invention to provide a device for dispensing dry shampoo in a cleaner, more accessible form.

In one embodiment, the cartridge containing the dry shampoo solution is embedded in an applicator device. When activated via an on-button, dry shampoo solution is dispensed through the pump in measured amounts onto a series of tips or teeth with small openings. When the user combs or scrubs the hair, the solution glides over the hair.

In one embodiment, the device releases hair and scalp products into a vapor cloud (mist) via ultrasound. This has the advantage that the product spreads smoothly, reducing wasted amounts and improving coverage control. This solution contrasts with aerosol spray cans, which spray more than necessary and produce a large cloud that sufficiently covers the area outside the user's head.

In one embodiment, the multipurpose device includes a new brush or comb tip for spraying.

In one embodiment, each tip consists of a combination of a half-cylinder anode conductor and a half-cylinder cathode conductor separated by a non-conductive gasket (insulator).

In one embodiment, each brush (or comb) tip is a cylindrical chamber longitudinally divided into two or more coaxial cylinders electrically insulated from one another or two or more chambers electrically insulated from one another.

In one embodiment, the tip has a positive terminal that can be used to provide a microcurrent to the scalp, where the scalp acts as a ground (GND) path.

In one embodiment, a brush (or comb) tip may provide a microcurrent to the scalp, where the scalp acts as a conductive path between the positive and negative terminals of the different tips.

In one embodiment, a microcurrent may be administered between multiple tips, with one tip serving as the anode source terminal and the other acting as the GND terminal.

In one embodiment, impedance may be measured between the positive and negative terminals to determine the scalp moisture level.

In one embodiment, impedance may be measured between multiple tips to determine scalp moisture levels over a larger area.

In one embodiment, impedance may be measured between the positive or negative terminal and the scalp (via the return path to the handle) to determine if the tip is in contact with the scalp (skin). This is useful when scalp contact is required for application; For example, in formula treatments and vacuum systems, there is a risk that the vacuuming device will suck the hair if the scalp is to be treated and the vacuuming is not applied directly to the scalp.

In one embodiment, a Light-Emitting Diode (LED) can be placed at one end of the tip and powered by two terminals.

In one embodiment, depending on the power of the LED, heat dissipation can be absorbed (heat sink) by the conductive material.

In one embodiment, the LED is placed at the far end of the tip. In this configuration, the LED can deliver more energy to the scalp compared to being placed at the base of the tip or delivered through a long fiber optic path.

In one embodiment, LEDs may be used to indicate treatment, curing formula, or device status (ie, mode of operation or charge status).

In one embodiment, a series of laser-cut holes (perforations) along the length of the tip are used to deliver the formula to the scalp and hair.

In one embodiment, individual openings only at the far end of the tip can be used when targeting only the scalp.

In one embodiment, the function of the tips and their split conduction halves may be controlled by microprocessor circuitry within the base body of the brush or comb device.

In one embodiment, the brush or comb tip is non-conductive, and a multi-cylinder configuration is useful where the application involves mixing or dispensing the formula and vacuuming it into small, controlled, targeted areas of the scalp. can do.

In one embodiment, a hand-held sized brush or comb device includes massage tips that are individually controlled in XYZ motion by actuators. The tips individually dispense precisely metered amounts of scalp product only when in contact with the scalp (either open/shorted or via the use of a dielectric skin contact sensor). Individually activated tips spray hair product (dry shampoo or color tint) in tightly controlled formulations (ie flat fan formulations). Custom scalp and hair products are housed in interchangeable cartridges. Adding a camera can diagnose scalp and hair conditions related to hair density, tone and dryness. Adding LEDs can further treat hair, facilitate camera imaging, and can be used for formula curing.

A number of scalp and hair treatment devices are known. For example, reference may be made to prior documents 2005/0081871, 2014/0088522, 2017/0150810, 2017/0326020, 2019/0098977, 2019/0209077 of the present application. In accordance with the present invention, a device for treating hair or scalp or both hair and scalp may be improved by including a sensor that detects the precise position or proximity of the device with respect to the scalp and hair. Devices with these sensors can use the information to control the treatments delivered.

In accordance with the present disclosure, providing a sensor is more "intelligent" that can be programmed to adjust a treatment based on the position or proximity of the hair treatment device to the scalp or hair or whether the device is actually in contact with the hair or scalp. provides an "enemy" device. Examples of hair and scalp treatment systems include, but are not limited to, scalp massagers, hair dryers and dispensers for shampoo, bleaches, colorants and other agents.

In one embodiment, the hair and scalp treatment system according to the present invention is implemented as a hand-held, electrically powered device. The device shown in the figures is an example of a hair or scalp treatment system. However, previously known hair and scalp treatment devices may be modified to have the intelligent functions described herein. For example, apparatus 100a of FIG. 1 shows relatively large tines that can be used to dispense formulations, perform with a vacuum or blower, and provide light and electrostatic treatments. However, in other embodiments, the tines may be replaced with a brush-like head with bristles or a comb with teeth.

People are washing their hair less and less often with traditional wet, water-based shampoos. A number of reasons can be given for the reduction of this type of shampoo, such as preventing hair loss and hair damage or saving time and energy. Dry shampoo is trending. People are trying to extend the time between salon visits to save money, which is driving interest in tinted dry shampoos for trimming roots. Dry shampoo is usually packaged in a spray bottle. However, spray bottles can inhale the product and inadvertently spray it on the face, especially the eyes. Spray bottles are inaccurate in both spray direction and spray amount. Also, spray bottles are not suitable when traveling or using public toilets. Dry shampoo doesn't cleanse your scalp and can actually damage it. Nevertheless, there is a belief that scalp care leads to healthy hair. The 'dry' way to clean the scalp is to apply oil to the hair by brushing or trimming. Scalp treatments and scalp-specific formulas can be applied via pipettes, foams or powders, and require manual hair parting. Powder and foam stick to your hands. Excessive product dripping onto the scalp can cause shedding and greasy hair. There is a growing demand for reusable, closed-loop product designs.

The present invention relates to devices for washing hair that can be used, for example, with dry shampoo or other formulations. Scalp and hair formulations exist to treat dandruff, hair loss, stress reduction, itching, color and tone, oiliness, appearance, frizz, volume, shine, dryness, density, and the like. But there is a need for smarter ways to apply formulations to the scalp and hair.

In one embodiment, the device uses a brush or comb-like structure that relies on a combination of mechanical and chemical action to deposit the desired agent for cleaning, remove the agent with unwanted particulates, and additionally has cosmetic or health properties. provide additional The comb-like action provides a familiar gesture that can be easily incorporated into current beauty and haircare routines. Additionally, the device may include hollow conductive tips arranged in a brush or comb configuration. The conductive tip allows several options. For example, a conductive tip can be used with a microcurrent generator, or a conductive tip can be used with an electrostatic charger to positively or negatively charge the scalp or hair to attract the hair agent to the charged area. there is.

In one embodiment, the device is provided with a tine or tip that utilizes a hollow structure to allow more precise delivery of the agent. In one embodiment, tines and tips may be used to provide microcurrent or electrostatic charge to the scalp and hair. In one embodiment, the tip may be used as a contact sensor. In one embodiment, the tip may be used to measure impedance to determine moisture content.

In one embodiment, the device is shaped in the style of a well-recognized and familiar hair appliance to inspire trust and confidence in the device leading to intuitive use and gestures when using the device.

Referring to FIGS. 1-5 , one embodiment of device 100a includes a handle 104 coupled to a substantially cylindrical section 138 . Handle 104 is connected to device 100a at an obtuse angle with respect to the front end of device 100a. The handle 104 helps balance the weight of the device for more comfortable use and easier control. Control buttons are also on the steering wheel.

Referring to FIG. 3 , at the rear, the device 100a may include a smaller diameter cylindrical housing 136 housing a removable cartridge 102 containing a hair or scalp treatment formulation. Cartridge 102 may be configured as a refillable cartridge or a disposable cartridge. In one embodiment, device 100a may be configured to hold one or more cartridges 102, where each cartridge may be filled with a different formulation for a different treatment. Alternatively, some applications may use two or more different formulations where both formulations must be applied to achieve the intended effect.

Forward from the rear housing 136, the device 100a contour increases stepwise to an outer diameter portion 138 that is larger than the housing 136 diameter. In one embodiment, the device 100a includes a body structure having a substantially cylindrical or minimally tapered conical portion 138 from the rear end to about halfway through the length of the device. In one embodiment, handle 104 is coupled to the back of conical portion 138 . Then, proximally from the cylindrical or least conical portion 138, the device 100a is placed in a top-to-bottom plane (i.e., viewed from the left or right) from approximately the middle of the device 100a to about 1/3 or 4 of the device length. ) takes a more pronounced conical or decreasing elliptical shape (140). However, in a side-to-side plane (ie, viewed from the top or bottom), device 100a does not taper enough to accommodate three tines in a side-to-side plane. As described herein, tines 108 may be replaced with tips arranged in a brush or comb configuration.

Then, distally from the smaller end of the conical or elliptical shape 140, the device 100a has a transition portion 142 at the front end forming one or more spray tines 108, each tines 108 is separated from others. Although tines 108 are illustrated in the context of a hair or scalp treatment system, device 100a may be configured as a brush or comb.

2 and 5, each tine 108 has a conical shape that progressively decreases from the initial connection at the transition portion 142 section to the end of the tine 108 in both the side-to-side plane and top-to-bottom plane. have a shape

In FIG. 5 , tines 108 are shown having rounded tips when viewed in a lower (or upper) plane. However, in FIG. 3 the tines 108 are shown having a flat area or chamfer at the bottom of the tines 108 at the front end when viewed in a side plane, resulting in a truncated round shape. The rounded tips of tines 108 can separate the hair for better access to the scalp and root. Rounded tines 108 include chamfered angles and “agitation bumps” for cleansing and massaging action.

In FIG. 5 , the chamfered section of tines 108 has an opening 130 for dispensing one or more agents. In one embodiment, the opening 130 may be static, meaning that the spray or spray direction cannot be set and adjusted. In one embodiment, the opening 130 may be directional, meaning that the spray or spray direction may be controlled. For example, the opening 130 may be provided in a swivel ball controlled through a micro actuator. In one embodiment, multiple openings may be provided, where each opening is oriented in a different direction, and the formulation is dispensed from selected openings in a preferred orientation.

In one embodiment, controlling the direction of spraying of the agent also permits application of the agent in a pattern such as, for example, a front-to-back “brush stroke” or circular pattern. In one embodiment, the dispenser 112 may control the form in which the formulation is dispensed. For example, the formulation can be sprayed in various types of patterns such as flat fan vs. cone, wide spray vs. narrow spray, solid spray vs. hollow, and stream vs. mist. In one embodiment, the formulation is dispensed through an adjustable conical nozzle that moves back and forth around a central stem to adjust the spray pattern.

In one embodiment, the formulation may be dispensed as a liquid. In one embodiment, the formulation may be atomized and dispensed as a mist. Additionally, the chambered section of tines 108 has an opening 132 leading to a vacuum system for collecting used agents with oil or debris removed from the hair. In one embodiment, opening 132 may be used to supply heated air so that device 100a functions as a hair dryer.

In the embodiment, each tine 108 is shown having an opening 130 for spraying and an opening 132 for a vacuum device. However, in one embodiment, there may be dedicated tines having only openings for agent dispensing and dedicated tines having only openings used for vacuum. In one embodiment, there may be multiple openings in each tine 108 for dispensing different formulations from the same tines. This can be advantageous when the two agents work together to achieve the intended effect. In one embodiment, each opening may be assigned to a different formulation. In one embodiment, apparatus 100a is provided with three tines 108 for uniform cleaning coverage. The angle of the handle 104 and the length of the tines 108 allow the user to reach all areas of the scalp and hair.

In one embodiment, device 100a includes an electrostatic treatment system. In one embodiment, the purpose of the electrostatic system is to charge a portion of the scalp or hair or both by induction or contact. In one embodiment, electrode 150 is disposed at the tip of tine 108 . Electrode 150 may also electrostatically charge hair formulation droplets as they are dispensed from opening 130 . The charged hair formulation will then be attracted or repelled to the target area of the scalp or hair depending on the specific charge created. The electrode 150 is electrically connected to the electrostatic charger. In one embodiment, electrode 150 may be surrounded by an electrically insulative material. In one embodiment, device 100a may have multiple hair and scalp treatment systems. Device 100a is also provided with one or more sensors including contact sensors, proximity sensors, accelerometers, and the like. The sensors provide inputs to the controller and the controller controls the output of one or more hair and scalp treatment systems according to the information provided by the sensors.

Referring to FIG. 6 , an apparatus 100a is shown schematically to illustrate the use of the sensor with a hair and scalp treatment system. Apparatus 100a includes a formulation dispenser 112, an electrostatic charger 152, a vacuum and collector system 114, a blower and heater system 144, a light treatment system 146 and a haptic vibration massager 158. It may have more than one treatment system, including but not limited to. In one embodiment, device 100a may include one of the treatment systems described above, one of the treatment systems, or a combination of one or more treatment systems.

In one embodiment, device 100a may be powered by alternating current (AC) or direct current (DC). In one embodiment, device 100a is powered through common household alternating current, which relies on an electrical cord (not shown) to power device 100a. In one embodiment, device 100a is powered through direct current, such as a rechargeable battery that can be charged by plugging into a household AC outlet. The direct current power supply 100a allows the device to be used without staying or standing near an electrical outlet.

In one embodiment, the device 100a includes a formulation dispenser 112 . In one embodiment, formulations are stored in replaceable or refillable cartridges 102 . Cartridge 102 may be removed from device 100a for refill or disposal, or may be discarded and replaced with a new, full cartridge. Once empty, the cartridge 102 can be replaced with a new cartridge filled with the same or a different formulation or the cartridge can be refilled with the same or a different formulation. As shown in Figure 1, cartridge 102 is inserted through the back of device 100a. Cartridge 102 is connected to supply scalp or hair formulation to dispenser 112 . In one embodiment, device 100a may hold multiple cartridges, where each cartridge is filled with a different formulation, which may be sprayed to perform different treatments and to different areas of the scalp and hair.

In one embodiment, cartridge 102 has a product identification tag 154 (FIG. 1) that can communicate commands for operation of device 100a based on a particular agent contained in cartridge 102. The device 100a may include a product identification tag reader 156 (FIG. 1) capable of reading the product identification tag 154 and processing the encoded signals into commands for operation and control of the device based on the particular formulation. there is. Product identification tags include, for example, barcodes, 2-D barcodes, RFID, and the like. A product identification tag is encoded into a machine readable signal conveying device settings for a particular formulation. Different formulations may have different device settings. For example, product identification tags may include heat or vacuum settings and dispenser settings from liquid to fine, medium, or coarse droplets. Other formulations may be used to treat different areas of the scalp and hair. Other agents may be used to provide different treatments to the scalp and hair.

In one embodiment, the product identification tag identifies an agent in the cartridge 102 that contains charged particles that control the device 100a to turn on the electrostatic charger 152, the product identification tag is a specific voltage and cathode or Further determine electrostatic settings, such as the polarity of the anode.

Dispenser 112 may dispense one or more formulations through tines 108 (or brush bristles or combs) as a fine mist or liquid. In one embodiment, dispensing the formulation as a mist or liquid may change the viscosity of the formulation that the device dispenses. In one embodiment, dispenser 112 includes a press, pump, or ultrasonic generator to generate a mist from the formulation. In the case of a pump or pressurized dispenser 112, such dispenser 112 causes a high velocity flow of air or formulation to propel the formulation through a fine nozzle designed to mist the opening 130. In the case of a pump or pressurized dispenser, a single dispenser 112 may be disposed in the device 100a. The outlet of the compression or pump dispenser 112 then passes through the conduit system to each tines 108 and exits the nozzle at the opening 130 .

In one embodiment, dispenser 112 is an ultrasonic atomizer having an ultrasonic generator that contacts the formulation at a frequency of ultrasonic waves sufficient to create a mist. Ultrasonic nebulizers also include "mesh" nebulizers, which have a vibrating mesh that directly touches the surface of the formulation to create a mist. Both types of ultrasonic nebulizers can use piezoelectric elements.

In one embodiment, device 100a includes an electrostatic charger 152 . Electrostatic chargers can create positive or negative charges on targeted areas of the scalp or hair or both. Electrostatic charger 152 is connected to electrodes 150 at the ends of one or more tines 108 via electrical conductors. A suitable electrode 150 is electrically conductive and may include, for example, copper, nickel, stainless steel, aluminum or alloys of any of these. Electrode 150 may be insulated from the surrounding area by an electrically insulating material such as plastic, elastomer, or the like.

As the device 100a is operated, the electrostatic charger 152 can create a positive or negative charge on the scalp or hair or both, attracting or repelling the agent to the charged area. In one embodiment, positively charged regions are created by pushing electrons away from the region, and in another example, negatively charged regions are created by attracting electrons into the region. Electrostatic charging may be performed by contact electrical charging, induction electrical charging, or the like. In one embodiment, electrode 150 is connected to a high voltage source to induce a positive or negative static charge.

In another example, the hair formulation is charged while passing through the charging electrode 150 . The negatively charged hair formulation droplets are drawn towards a target that may be at a lower potential.

In one embodiment, apparatus 100a includes a vacuum system 114 having a vacuum generating motor and a collector. In one embodiment, the motor may be a variable speed motor. The motor directs an air stream entering through the openings 132 of the tines 108 . The air stream may carry the used agent along with the oil and debris washed from the hair by the agent, which is captured by the collector and the air blown out of the device 100a. In one embodiment, the collector is disposed at the rear of the device 100a and includes an annular vent 134 surrounding the cartridge 102 (FIG. 4). Vent 134 allows the air stream to exit the apparatus 100a, while used and debris are trapped in the collector. In one embodiment, the collector is removable from the device 100a and is dishwasher safe so that it can be washed in the dishwasher. In one embodiment, the surface of the collector in contact with the agent used is coated with a hydrophobic or hydrophilic material to facilitate cleaning of the collector.

In one embodiment, apparatus 100a includes a blower and heater system 144 . In one embodiment, device 100a may function as a hair dryer. Blower and heater system 144 may utilize a vacuum motor configured to rotate in opposite directions. When a vacuum is created to draw air through tines 108 , blower and heater system 144 is configured to expel air through tines 108 . When operating as a blower, the impeller vanes discharge the air stream through openings 132 in tines 108. Prior to venting, the air stream may first pass through a resistance heater coil. The temperature of the air can be raised or lowered by controlling the current applied to the heater coil. Air exhausted from the tines may enter the impeller vanes through an annular exhaust port 134 located at the rear of the device 100a.

In one embodiment, device 100a includes a light treatment system 146 . In one embodiment, the light treatment system includes one or more light emitting diodes 146 (LEDs) capable of producing light across a wide range of the electromagnetic spectrum. In one embodiment, phototherapy has been used on the scalp to treat skin conditions. In one embodiment, light therapy is used to stimulate cells in hair follicles. However, light therapy may have other benefits. In one embodiment, phototherapy is performed by light emitting diodes 146 (LEDs) capable of producing electromagnetic energy in a wide range of wavelengths (individual wavelengths such as laser LEDs or multiple wavelengths in a wide range). The intensity of the light produced by the LED can be varied, for example by controlling the current.

In one embodiment, accelerometer 164 is a two-axis and three-axis accelerometer that functions to determine device 100a orientation or device 100a position with respect to the head and hair. For example, device 100a is generally held in different orientations when used on the crown, left and right sides, rather than the back. Two-axis and three-axis accelerometers 164 are used to track the orientation of device 100a from which position can be determined. Accelerometer 164 is shown on tines 108, but the accelerometer could be placed anywhere on device 100a.

In one embodiment, contact sensor 160 includes an open or short detector or a dielectric sensor.

In one embodiment, infrared or camera sensors or both may be located at various locations throughout device 100a. In one embodiment, the camera may be a semiconductor integrated circuit that converts light into an image, such as a charge coupled device (CCD) or pixel sensor. Infrared sensors detect heat that is inversely proportional to the distance from the heat source to the device. However, other examples of proximity sensors such as capacitive, ultrasonic or Doppler sensors may also be applied.

In one embodiment, accelerometer 164 functions to determine device 100a position (or position relative to the head), device 100a orientation, and device 100a movement. In one embodiment, accelerometer 164 may be used in combination with other sensors including geomagnetic sensors (ie, compasses) and gyroscopes.

In one embodiment, device 100a includes controller 148 . In one embodiment, controller 148 is a digital device. The controller 148 may include one or more hardware circuits coupled to a printed circuit board, or all circuits may reside on a single chip. Controller 148 may include at least a microprocessor core and memory. The hardware can be designed for use in small manual devices. A microprocessor may be implemented as multiple processors working cooperatively in parallel and serial to carry out instructions according to pre-programmed logic.

Controller 148 receives signals from sensors such as contact sensor 160 , proximity sensor 162 , and accelerometer(s) 164 . Sensors 160 , 162 , and 164 may include circuitry that provides digital signals for storage and processing by controller 148 . In an embodiment, one or more sensors may transmit analog signals that are converted to digital signals by analog-to-digital converter circuitry before being stored and processed by controller 148.

The controller 148 may perform various actions based on one or more signals provided by the sensors. Additional information may also be available to the controller 148, such as a clock to count the passage of time and historical data from sensors.

The controller 148 converts and interprets the signals from the sensors to mean spatial conditions of the device 100a, such as contact or no contact with the device 100a, distance from the device 100a, and scalp And it can be interpreted as indicating the position of the device (100a) in relation to the hair. Controller 148 will then perform certain pre-programmed commands based on one or more signals. Instructions can be encoded in hardware or software. The instructions relate whether and how to change the operation of one or more treatment systems based on signals from the sensors.

In one embodiment, each treatment system 112, 152, 114, 144, 146 has a treatment protocol that specifies which treatment should be provided based on real-time spatial conditions of the device 100a. In this way, the controller 148 provides command signals to the treatment systems 112, 152, 114, 144 and 146 to adjust the treatment as the user moves the device 100a to different areas of the scalp and hair. send. Controller 148 bases its commands on currently (in real time) detected spatial conditions of device 100a. Spatial conditions may relate to the contact, distance and position and orientation of the device 100a from the hair and scalp. A treatment protocol can be provided with any tabular data or function that associates an area or distance to the scalp or hair with treatment conditions. For example, a hair dryer may be controlled to change the air temperature proportional to the distance the device 100a moves away from the hair. In this example, the treatment protocol would be air temperature as a function of distance or, in tabular data, a table with a row for each temperature setting and a column for each distance setting, where the intersection of the row and column would be the spatial condition ( In this example, it provides the processing temperature for distance). Treatment protocols for other treatment devices may be established based on other spatial conditions in a similar manner.

Instructions corresponding to each treatment protocol may be stored on any tangible computer readable medium or computer storage device and may be stored and executed on one or more microprocessors. Instructions may be stored in high-speed memory such as EEPROM, flash memory, RAM or other programmable non-volatile memory. Commands can be written in programming languages such as C, C++, COBOL, JAVA™, PHP, Perl, HTML, CSS, JavaScript, VBScript, ASPX, Microsoft .NET™, Go, etc.

A treatment protocol for the dispenser 112 based on the spatial conditions of the device 100a may change the nature of the sprayed agent from a liquid to a mist, for example depending on whether the agent is directed to the scalp or the hair, or to spray The direction of the agent being applied can be completely changed or stopped by sensing the position of the device 100a relative to the hair or not sensing any hair. The treatment protocol also takes into account the type of formulation to be dispensed, ie whether the formulation is a skin or scalp treatment or a hair treatment. When device 100a holds one or more cartridges, device 100a may be configured to dispense a different agent based on sensing that the device moves from a first location to another location, wherein the treatment protocol Invoke another formulation to be dispensed at the second location.

A treatment protocol for electrostatic charger 152 based on spatial conditions of device 100a determines electrostatic parameters based on whether device 100a is within or in contact with a maximum distance with respect to the scalp (skin) or hair. This may include changing

A treatment protocol for the vacuum device 114 based on the spatial conditions of the device 100a is to reduce the force of the vacuum based on contact with the skin or scalp, and the further the device 100a moves away from the skin or scalp, the more the vacuum may include increasing

The treatment protocol of the blower heater 144 according to the spatial condition of the device 100a lowers the force and temperature of the air according to contact with the skin or scalp, and the blowing force ( blowing force) and increasing the temperature.

A treatment protocol for lighting system 146 based on the spatial conditions of device 100a can turn on specific light therapies based on contact with skin or contact with hair, or select a light therapy based on distance. This may include increasing or decreasing the power, or turning off the light therapy if there is no contact or a distance beyond which the light therapy is not effective. In one embodiment, different light emitting diodes can be illuminated based on detecting the device moving from a first location to another, and the treatment protocol calls a different LED based on the second location.

7 is a flow diagram illustrating one embodiment of the operation of device 100a to change or adjust the operation of a hair or scalp treatment system based on spatial conditions of device 100a.

In one embodiment, at start block 702 , device 100a may turn itself on when device 100a detects that it has been picked up by a user according to a signal from accelerometer 164 . From block 702, the device enters block 704.

In one embodiment, when device 100a is being used for more than one treatment, i.e. device 100a has more than one treatment system 112, 152, 114, 144, 146, the user may block 702. ) to select a treatment system. If device 100a has a single treatment system, block 702 may be omitted. From block 704, device 100a enters block 706.

At block 706, device 100a reads the treatment protocol based on the selected treatment system. Here, "read" can mean accessing or storing the treatment protocol in a way that can be used by the controller 148 . The treatment protocol may be stored in memory of the controller 148 . The treatment protocol specifies the treatments to be provided by the treatment system according to the changing spatial conditions of the device. Spatial conditions may refer to one or more conditions indicating contact or non-contact with device 100a, distance from device 100a, and location of device 100a relative to the scalp and hair. The treatment systems 112, 152, 114, 144, and 146 may determine the treatment delivered by the treatment systems based on device 100a contact, device 100a distance, and device 100a position relative to the scalp or hair. can be changed in real time. The device enters block 708 from block 706.

At block 708, the device 100a receives the sensor data in real time and interprets the data to determine the spatial conditions of the device 100a. For example, spatial conditions that can be determined from the sensor include contact or non-contact with device 100a, distance of device 100a to scalp and hair, and position of device 100a to scalp or hair. Device 100a enters block 710 from block 708 .

At block 710, device 100a compares the current spatial conditions of device 100a to a pre-programmed treatment protocol. Apparatus 100a enters block 712 from block 710 .

At block 712, the device 100a adjusts the treatment system according to the treatment protocol for the current spatial conditions of the device 100a. For example, if the treatment system selected is formulation dispenser 112, the treatment protocol for dispenser 112 (for hair roots) may use a different setting or formulation for scalp contact, and device 100a may Different jetting settings or formulations may be used as they move further away from the scalp. For example, the formulation can be dispensed as a liquid when the device 100a contacts the scalp, and the dispenser 112 reduces the amount or applies the formulation as a finer mist as the distance from the scalp increases. The treatment protocol for the blower and heater 144 may invoke minimum heat and airflow settings when contact with the scalp is detected, and the treatment protocol may heat up as the distance of the device 100a from the scalp or hair increases. and a gradual increase in airflow. The protocol for the light treatment system 146 may call for the LED to turn on only when the device 100a is in contact with the scalp and turn off if there is no contact or the distance increases beyond the effective range of the light treatment. A treatment protocol for the LEDs may invoke different wavelength LEDs to illuminate depending on the area of the scalp sensed by the device. Commands to change treatment systems come from a controller 148 that communicates with each treatment system.

If device 100a is lowered, such as when device 100a has not detected motion for a predetermined amount of time determined by the accelerometer, device 100a may reduce power or be in a standby mode.

The use of the device 100a minimizes the effect on the hair style, and since the overall shape of the device 100a is familiar to other hair appliances such as a hair dryer, the device 100a can be used simply and intuitively. In addition, device 100a does not require hand contact with the hair formulation. Apparatus 100a adds features that make operation simpler, and tailoring the treatment to the specific spatial location of the apparatus minimizes debris and prevents mist from dispersing into the air where it can be inhaled.

In one embodiment, the tip 602 may omit an opening along the length of the tip, and the tip 602 is provided with an opening only at the very end to permit use of the tip 602 for scalp treatment. In this way, two different agents can be delivered from tip 602 through half cylinder 604 and half cylinder 606 .

In one embodiment, the end of the tip 602 includes a perforated flat or domed disk with a small opening 610 in the first half cylinder 604 and an opening 612 in the second half cylinder 606. In one embodiment, instead of disks, half cylinders 604 and 606 may be fully open at the ends.

In one embodiment, the inner cylinder 1704 and the outer cylinder 1706 are not coaxial with each other, but the inner cylinder 1704 can be placed against an inner wall of the outer cylinder 1706 so that there is no separation from the inner cylinder 1704. The opening may only need to cross the wall of the outer cylinder 1706, so there is no need to connect the opening through a tube. Insulators may need to be placed between the inner cylinder 1704 and outer cylinder 1706 for electrical isolation. In either configuration, two different agents can be delivered from the tip 1702 through the inner cylinder 1704 and the outer cylinder 1706.

Formation may also be included.

In one embodiment, a hair formulation comprising a cationic, anionic or zwitterionic polymer and a surfactant may be used to provide an electrical charge to the formulation capable of interacting with the hair or scalp. In one embodiment, the hair formulation acts on a complex molecule that interferes with other substances, for example, charged interactions between charged substances and with hair fibers, resulting in more efficient charged interactions, such as metal ions. It may be charged with other substances such as chelating agents.

Given that hair possesses an electric charge (usually negative at neutral pH), this charge provides better and more efficient attraction/deposit or repulsion and aided removal to the hair. can be affected by the presence of charged substances (eg, the substances described above) in the formulation.

Dispenser 112 may dispense one or more formulations through tines 108 and tips 602 , 1702 , 802 , 1100 , 1200 in the form of a fine mist or liquid or any in-between. In one embodiment, dispenser 112 includes a press, pump, or ultrasonic generator to generate a mist from the formulation. In the case of a pump or pressurized dispenser 112, such dispenser 112 causes a high velocity flow of air or formulation to propel the formulation through a fine nozzle designed to mist the opening 130. In the case of a pump or pressurized dispenser, a single dispenser 112 may be disposed in device 100b. The outlet of the compression or pump dispenser 112 then passes through the conduit system to each tines 108 and exits the nozzle at the opening 130 .

In one embodiment, the dispenser 112 is an ultrasonic atomizer that creates a mist or vapor to dispense the formulation. This has the advantage of gently dispensing the formulation to reduce the amount of debris and improve coverage control. In one embodiment, the nebulizer uses an ultrasonic generator in contact with the formulation where the frequency of the ultrasonic wave is sufficient to create a mist. Ultrasonic nebulizers also include "mesh" nebulizers, which have a vibrating mesh that directly touches the surface of the formulation to create a mist. Both types of ultrasonic nebulizers can use piezoelectric elements.

In one embodiment, dispenser 112 is activated by depressing switch 106 (FIGS. 1 and 2). In one embodiment, the switch 106 is positioned on the upper front surface of the handle 104 so that it can be operated with an index finger. In one embodiment, switch 106 is a momentary switch whose default position is an off position. The momentary switch can dispense a metered amount of agent with just one actuation, regardless of the operating time. Pressing the momentary switch 106 longer does not dispense more agent than the pre-measured amount. In another embodiment, switch 106 is an on-off switch that starts and stops dispenser 112 based on the opening and closing of the switch.

Suitable conductive materials for tips 602, 1702, 802, 1100 and 1200 may include, for example, copper, nickel, stainless steel, aluminum or alloys thereof.

In one embodiment, device 100b includes a microcurrent generator 1158. The microcurrent generator 1158 supplies a small amount of current (microcurrent) to the skin or scalp within a given frequency range by providing voltage across the positive terminal and the negative terminal (GND). In one embodiment, the amount and frequency of electrical stimulation may be within the range of naturally occurring electrical processes in tissues and cells. For example, microcurrent therapy has been used to stimulate hair growth, heal damaged tissue, and rejuvenate the skin through collagen stimulation and increased blood flow. In one embodiment, generation of the microcurrent is provided by a waveform generator. The controller 148 sends a modulated waveform signal in which the desired amplitude, frequency, and polarity of the current are set.

In one embodiment, tips 602 , 1702 , 802 , 1100 and 1200 are coupled to a microcurrent generator 1158 . Tips made of conductive material (602, 1702, 802, 1100 and 1200) allow one of the cylinders of the tip to act as a positive terminal, which can be used to supply microcurrent to the scalp acting as a ground (GND) path. This may also include the skin and tissue between the scalp and the negative terminal placed in contact with the hand, such as handle 104 of device 100b. In one embodiment, a microcurrent may be administered between multiple tips where one tip serves as a positive terminal and the other tip serves as a GND terminal.

In one embodiment, tips 602, 1702, 802, 1100 and 1200 made of conductive material also allow the tips to act as sensors. In one embodiment, one of the cylinders of each tip 602, 1702, 802, 1100 and 1200 may serve as the positive terminal, while a second cylinder of the same or a different tip serves as the negative terminal. In one embodiment, impedance can be measured between any positive terminal and any negative terminal to determine the scalp moisture level at a specific point or over a more general area.

In one embodiment, impedance can be measured from different tips to determine scalp moisture levels over a larger area.

In one embodiment, impedance may be measured between the positive or negative terminal and the scalp (through the conductive return path to the handle) to determine if the tip is in contact with the scalp (skin). This is useful when scalp contact is required for application; For example, in formula treatments and vacuum systems, there is a risk that the vacuuming device will suck the hair if the scalp is to be treated and the vacuuming is not operated directly on the scalp.

In one embodiment, tips 602 , 1702 , 802 , 1100 , and 1200 are coupled to an electrostatic charger 152 . In one embodiment, the electrostatic charger 152 is used to create a positive or negative charge on the scalp or hair or both to attract or repel the agent to the charged area. Conductive tips 602, 1702, 802, 1100 and 1200 allow the tips to act as electrodes. In one embodiment, a positively charged region is created by pushing electrons away from that region, and in another embodiment, a negatively charged region is created by attracting electrons into that region. Electrostatic charging may be performed by contact electrical charging, induction electrical charging, or the like.

In another embodiment, the agent is charged while passing within tips 602, 1702, 802, 1100 and 1200. The negatively charged hair formulation droplets are drawn towards a target that may be of a lower potential.

In one embodiment, apparatus 100b includes a vacuum system 114 having a vacuum generating motor and collector 116 . In one embodiment, the motor may be a variable speed motor. The vacuum motor 114 is connected to the impeller vanes that allow the air stream to enter through the vacuum inlet openings 132 in the tines 108 or, in the case of tips 602, 1702, 802, 1100 and 1200, one of the cylinders can be used for The motor directs the air stream through an opening 132 in one of the cylinders of the tines 108 or tips 602, 1702, 802, 1100, 1200. The air stream may carry the used agent along with the oil and debris washed from the hair by the agent, and is captured by the collector 116 and the air exhausted out of the device 100b. In one embodiment, collector 116 includes an annular vent disposed on the back of device 100b. The vent allows the air stream to exit the apparatus 100b while used and debris are trapped in the collector 116.

In one embodiment, the vacuum motor 114 is actuated by a multi-position, multi-function selector switch 110 (FIG. 4). The selection switch 110 may be, for example, a slide switch, a dial switch having two or more positions, or a push button switch having two or more positions. In one embodiment, the vacuum selector switch 110 includes a setting for off and one or more vacuum speed settings such as high and low. In one embodiment, the vacuum switch 110 is located on the lower back of the handle 104 so that it can be operated with the thumb, for example. The vacuum switch 110 can be isolated for uninterrupted vacuum. A light emitting diode 118 can be used to illuminate the selected location. Select switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch can replace the selector switch, the default position of the momentary switch is the off position, the momentary switch must be depressed to start the vacuum motor. In one embodiment, device 100b includes both a vacuum selector switch and a momentary switch, wherein the momentary switch activates the vacuum motor when depressed and is used in the speed setting of the selector switch.

In one embodiment, device 100b includes controller 148 . In one embodiment, controller 148 is a digital device. The controller 148 may include one or more hardware circuits coupled to a printed circuit board, or all circuits may reside on a single chip. Controller 148 may include at least a microprocessor core and memory. The hardware can be designed for use in small manual devices. A microprocessor may be implemented as multiple processors working cooperatively in parallel and serial to carry out instructions according to pre-programmed logic.

Commands for controlling the dispenser 112, the electrostatic charger 152, the microcurrent generator 1158, and the vacuum device 114 may be stored in the controller memory. Memory is any tangible computer readable medium or computer storage device that can be accessed and used by one or more microprocessors to carry out instructions. Instructions may be stored in high-speed memory such as EEPROM, flash memory, RAM or other programmable non-volatile memory.

In one embodiment, controller 148 communicates with dispenser 112 , electrostatic charger 152 , microcurrent generator 1158 and vacuum device 114 . The controller 148 may also interpret the information provided on the cartridge 102 to provide commands to the dispenser 112 and electrostatic charger 152 for a particular formulation. The controller 148 may configure one or more tips 602 , 1702 , 802 , 1100 , and 1200 to be electrically connected to the microcurrent generator 1158 and the electrostatic charger 152 . The controller 148 can be configured such that one or more of the tips 602, 1702, 802, 1100 and 1200 are connected to the dispenser 112 to deliver the formulation in a desired form and amount. The controller can control LEDs 1102 and 1202 to operate at specified powers and wavelengths.

In one embodiment, the controller 148 may serve as positive and negative terminals of the microcurrent generator 1158 by connecting one or more tips.

In one embodiment, controller 148 may connect one or more tips to act as electrodes for electrostatic charger 152 .

In one embodiment, the controller 148 may connect one or more tips to the positive terminal of the microcurrent generator 1158, and the scalp (skin) is part of the ground path to the negative terminal located on the device 100b.

In one embodiment, controller 148 may calculate the impedance between the positive and negative terminals of any one or more tips.

In one embodiment, controller 148 uses impedance to determine whether the tip is in contact with the scalp. In one embodiment, the controller 148 may turn off the vacuum 114 or not allow the vacuum to be turned on when it determines that one or more tips are not in contact with the scalp.

In one embodiment, controller 148 may use the measurement of impedance to determine moisture in one or more regions of the scalp.

In one embodiment, controller 148 may turn on LEDs 1102 and 1202 based on predetermined commands. For example, some formulations may require the application of specific wavelengths of light. Controller 148 can be used to control LEDs 1102 and 1202 to provide a light therapy treatment. The controller 148 has instructions for determining the wavelength and power to be applied to the light treatment.

In one embodiment, the controller 148 may control the amount of formulation dispensed by the dispenser 112 . For example, controller 148 may turn on a pump or compression for a predetermined amount of time associated with a particular amount of formulation. In one embodiment, dispenser 112 uses a positive displacement pump, so the volume displaced for each rotation of the pump can be measured with an encoder. When the rotation of the pump equals the volume of agent to be dispensed, the controller 148 can turn off the pump.

The use of device 100b is intuitive, and the overall shape of device 100b is familiar to users of other hair appliances, such as hair dryers, leading to simple and intuitive use of device 100b. Apparatus 100b may improve the existing use of aerosol dry shampoo. Device 100b dispenses a controlled amount of the formulation so that the formulation glides over the hair as the user combs or brushes the hair. Device 100b is contrasted with an aerosol spray can that sprays more than necessary and creates a large cloud that sufficiently covers the area outside the user's head.

16 and 17 are illustrations of one embodiment of a device 100d in which a plurality of different tips may be mounted. Device 100d is useful for washing hair that can be used with dry shampoo formulations having additional functions through individual activation of tips for spraying, sensing, massaging and other uses. In one embodiment, device 100d is a brush that relies on a combination of mechanical and chemical action to deposit desired formulations for cleaning, remove formulations with unwanted particulates, and further provide additional cosmetic or health attributes. Use a straight or comb structure. Intuitive gestures provide familiar gestures that can be easily incorporated into existing beauty and haircare routines. Device 100d may also include various types of hollow conductive or non-conductive tips 602, 1702, 1100 or 1200 arranged in a brush or comb configuration. Although a brush configuration is shown in the figure, device 100d may be configured with a comb configuration, i.e., a single row of tips. However, tips arranged in a brush configuration allow various advantages, such as individual actuation of the tips to apply one or more treatments, sprays or massages using only some but not all of the tips.

In one embodiment, device 100d includes massage tips that are individually controlled in XYZ motion by actuators. The tip individually dispenses precisely measured amounts of scalp product only when it touches the scalp (either open/shorted or via the use of a dielectric skin contact sensor). Individually activated tips spray the hair product (dry shampoo or color tint) in a tightly controlled form (i.e. in the form of a flat fan). Custom scalp and hair products are housed in interchangeable cartridges. Adding a camera can diagnose scalp and hair conditions related to hair density, tone and dryness. The addition of LEDs further treats hair, facilitates camera imaging, and can be used for formula curing.

In one embodiment, device 100d emits hair and/or scalp products as a vapor cloud (mist) via ultrasound (similar to a household humidifier). A gentler dispersion of product reduces the amount of waste and improves coverage control. These solutions contrast with aerosol spray cans, which spray more than necessary and create a large cloud that sufficiently covers the area outside the user's head.

In one embodiment, multipurpose device 1100 has individually controlled tips for dispensing formulations and other uses are described.

In one embodiment, each tip consists of a combination of a first half cylinder as a positive conductor and a second half cylinder as a negative conductor separated by a non-conductive gasket. In purely geometric terms, each tip is either a cylindrical chamber divided longitudinally into two or more isolated chambers, or two or more isolated cylinders attached to each other longitudinally.

In one embodiment, a tip serving as a positive terminal may be used to provide additional functionality to the tip. In one embodiment, a microcurrent may be provided to the scalp, where the scalp is a GND path comprising the skin and tissue between the scalp and a negative terminal placed in contact with the hand, such as handle 104 of device 100d. It works. The tip can provide a microcurrent to the scalp, and the scalp serves as a conduction path between the positive and negative terminals. Alternatively, microcurrents can be managed between multiple tips. Here, one tip is powered by the positive source and the other tip is powered by GND.

In one embodiment, the impedance between the positive and negative terminals may be measured to determine the scalp moisture level. Alternatively, the impedance can be measured between several tips to determine the scalp moisture level over a larger area. By measuring the impedance between the positive or negative terminal and the scalp (through the path back to the handle), you can verify that the tip is in contact with the scalp (skin). This is useful if the application requires contact with the scalp: for example, if the scalp is to be treated and the vacuum does not work directly on the scalp, there is a risk that the vacuum will suck the hair into the vacuum. Formula treatment with system.

An LED can be placed at the end of the tip and powered by two terminals. If the LED is powerful, the heat dissipation can be absorbed (dissipated) by the conductive material. The LED at the far end of the tip delivers more energy to the scalp than if it were at the base or delivered through a long fiber optic path. LEDs can be used to indicate treatment, curing agents, or device status (eg, mode of operation or charge status).

A series of laser-cut holes (perforations) along the length of the tip can be used to deliver the formulation to the scalp and/or hair. Alternatively, if you are only targeting the scalp, you can use the individual openings at the far end of the tip.

The functions of the tips and their split conduction halves can be dynamically controlled and reassigned by a central integrated circuit within the basic body of the brush device. Even if the tip is not made of a conductive material, the 'two or more cylinders' configuration can be useful for applicators that use a vacuum to mix or dispense formula onto small, controlled target areas of the scalp.

In one embodiment, the conductive tip allows for several options, for example the conductive tip can be used with a microcurrent generator, the conductive tip can be used as a sensing device to sense skin contact, or the conductive tip can be used as a beam of light. It can be used to power a light emitting diode (LED) for therapy, or the conductive tip can be used to provide vibration in one to three axes.

In one embodiment, device 100d is provided with a tip that utilizes a hollow structure to allow more accurate delivery of the agent. For example, the agent may be dispensed only from that tip to form a specific spray pattern. In one embodiment, the conductive tip is made with one or more hollow chambers extending the length of the tip that enable dispensing of one or more agents through the tip. In one embodiment, the tip is non-conductive but still includes a hollow chamber extending the length of the tip to provide a jetting feature.

In one embodiment, the device 100d is formed in a well known and familiar hair product style to inspire trust and confidence in the device leading to intuitive use and gestures when using the device.

Referring to FIGS. 16 and 17 , in one embodiment the device 100d includes a handle 104 coupled to a substantially cylindrical section 138 . Handle 104 is connected to device 100d at an obtuse angle with respect to the front end of device 100d. The handle 104 helps balance the weight of the device for more comfortable use and easier control. Control buttons are also located on the steering wheel.

Referring to FIG. 17 , at the rear, the device 100d may include a smaller diameter cylindrical housing 136 housing a removable cartridge 102 containing a hair or scalp treatment formulation. The device 100d allows easy replacement of the cartridge 102 to deliver different formulations. Cartridge 102 may be configured as a refillable cartridge or a disposable cartridge. In one embodiment, device 100d may be configured to hold one or more cartridges 102, where each cartridge may be filled with a different formulation for a different treatment. Alternatively, some applicators may use two or more different formulations where both formulations must be applied to achieve the intended treatment.

Forward from the rear housing 136, the device 100d contour increases stepwise to an outer diameter portion 138 that is larger than the cartridge housing 136 diameter. In one embodiment, the device 100d includes a body structure having a substantially cylindrical or minimally tapered conical portion 138 from the rear end to about the middle of the device length. In one embodiment, handle 104 is coupled to the back of portion 138 .

In one embodiment, device 100d has tips 602, 1702, 1100, 1200 arranged in a brush configuration such as concentric circles. Apparatus 100d includes a brush head 140 coupled to a central portion 138 . Brush head 140 is part of device 100d that holds tip 602, 1702, 1100, or 1200. In one embodiment, the brush head 140 is static and non-actuated relative to the device, since the individual tips are individually actuated to oscillate, so there is no need to have a brush head that rotates or oscillates. Further, the tips are configured to control the dispensing of the agent from some individual tips but not from other tips. This allows some tips to be “turned on” and others to be “turned off” to create different spray patterns at the brush head.

In one embodiment, tips 602 , 1702 , 1100 , 1200 are concentrically arranged in brush head 140 . In one embodiment, tips 602, 1702, 1100, 1200 are configured to dispense two different formulations. In one embodiment, tips 602, 1702, 1100, 1200 have hollow chambers extending the entire length of the tips. Tips 602, 1702, 1100, 1200 are at least one diameter in length. However, tips 602, 1702, 1100, 1200 can be configured to be of several diameters in length, so that the width to length ratio can vary from 1:1:1:20 or more. Tips 602, 1702, 1100, 1200 may or may not be flexible. Tips 602, 1702, 1100, 1200 may also be coupled to a brush head 140 of a flexible material. Separate chambers allow one or more agents to be delivered through each chamber without mixing. The agent may be separated within each chamber until the agent exits the chamber. Dispensing of the formulation can be accomplished by configuring each chamber with an opening along the length of the chamber or only at the end or along both the length and end of the chamber. Additionally, each chamber of the tip may have a valve or other means to control ejection from one or both chambers. Controlling agent dispensing only at a specific tip of the brush head allows dispensing in multiple patterns, such as cone spray, fan spray, and the like.

Referring to Fig. 18, one embodiment of an apparatus 100d is schematically represented to illustrate the main system.

In one embodiment, device 100d includes power source 128 . Device 100d may be powered by alternating current (AC) or direct current (DC). In one embodiment, device 100d is powered via common household alternating current, which relies on an electrical cord (not shown) to power device 100d. In one embodiment, device 100d is powered through direct current, such as a rechargeable battery that can be charged by plugging into a household AC outlet. The direct current power supply 100d allows the device to be used without staying or standing near an electrical outlet. Power supply 128 includes controller 148, dispenser 112, massage module 1152, vacuum motor 114, camera 2158, LEDs 1102, 1202 and tips 602, 1702, 1100 and 1200. ) is configured to provide power to any system that requires power.

In one embodiment, device 100d includes a formulation dispenser 112 . In one embodiment, formulations are stored in replaceable or refillable cartridges 102 . Cartridge 102 may be removed from device 100d for refill or disposal, or may be discarded and replaced with a new, full cartridge. Once empty, the cartridge 102 can be replaced with a new cartridge filled with the same or a different formulation or the cartridge can be refilled with the same or a different formulation. As shown in Figure 1, cartridge 102 is inserted through the back of device 100d. Cartridge 102 is connected to supply scalp or hair formulation to dispenser 112 . In one embodiment, device 100d may hold multiple cartridges, where each cartridge is filled with a different formulation, which may be sprayed to perform different treatments and to different areas of the scalp and hair. .

In one embodiment, cartridge 102 has a product identification tag 154 (FIG. 1) that can communicate commands for operation of device 100d based on a particular agent contained in cartridge 102. The device 100d includes a product identification tag reader 156 (FIG. 1) capable of reading the product identification tag 154 and processing the encoded signals into commands for operation and control of the device based on the specific formulation. can do. Product identification tags include, for example, barcodes, 2-D barcodes, RFID, and the like. A product identification tag is encoded into a machine readable signal conveying device settings for a particular formulation. Different formulations may have different device settings. For example, product identification tags may include dispenser settings from liquid to fine, medium, or coarse droplets. Product identification tags may also include dispenser pattern formations such as flat fan versus cone, wide versus narrow, solid versus hollow, and stream versus mist. there is. The product identification tag may also include instructions for operating the LEDs 1102 and 1202. Other agents may also be used to treat other areas of the scalp and hair. Other agents may be used to provide different treatments to the scalp and hair.

Dispenser 112 may dispense one or more formulations through tips 602 , 1702 , 1100 , and 1200 in the form of a fine mist or liquid or any in-between. In one embodiment, dispenser 112 includes a press, pump, or ultrasonic generator to generate a mist from the formulation. In the case of a pump or pressurized dispenser 112, such dispenser 112 allows air or formulation to flow at a high velocity pushing the formulation through a microscopic opening. In the case of a pump or pressurized dispenser, a single dispenser 112 may be disposed in device 100d. The outlet of the compression or pump dispenser 112 is then connected to each individual tip through a conduit system.

In an embodiment, the dispenser 112 is an ultrasonic atomizer that creates a mist or vapor to dispense the formulation through individual tips. This has the advantage of gently dispensing the formulation to reduce the amount of debris and improve coverage control. In one embodiment, the nebulizer uses an ultrasonic generator in contact with the formulation where the frequency of the ultrasonic wave is sufficient to create a mist. Ultrasonic nebulizers also include "mesh" nebulizers, which have a vibrating mesh that directly touches the surface of the formulation to create a mist. Both types of ultrasonic nebulizers can use piezoelectric elements.

In one embodiment, both the ultrasonic generator and the vibrating mesh nebulizer may use piezoelectric materials to generate vibrations at ultrasonic frequencies. In one embodiment, the same piezoelectric material used in atomizers may be used to drive the haptic system. Haptic systems may include massage therapy systems, but may also include any system that provides a sensory experience, such as thermal and related ultrasound therapy. Nebulizers may rely on generating frequencies above 1 MHz. Nebulizers capable of producing frequencies above 1 MHz can also be used to drive haptic systems that generate heat that can be used to treat skin and scalp alone or with a jet of formulation. Some nebulizers may also rely on ultrasonic frequencies below 1 MHz. In one embodiment, a nebulizer may be used to drive a haptic system to generate frequencies in a range designed to deliver treatment compounds to the skin and scalp along with a jet of formulation. Therefore, there is an advantage when using the piezoelectric material used in the atomizer system in the haptic system.

In one embodiment, each tip may include a valve at the inlet of one or both chambers. The valve has an actuator that opens and closes the valve. Each valve on each tip can be actuated to open or close independently of the other valves on the other tips. By opening or closing valves on each individual tip, the agent can be controlled to flow out of selected tips only in a controlled pattern such as conical, flat fan, stream, multi-stream, pulse, etc. There are also valves that control the dispensing in both chambers of the tip, and the agent can be controlled to flow out of one or both of the chambers.

19 is a schematic diagram showing the ends of tips 602, 1702, 1100, and 1200. In one embodiment, the tips are arranged in an increasing diameter circular pattern of small (908), medium (910) and large (912) diameter diameters. In one embodiment, only the valve of the tip connected by one of the circles 908, 910, or 912 can be opened and the small cone 908, middle cone 910, and large cone 912 can be sprayed with agent. Thus, small, medium and large areas of the scalp or hair can be covered. The controller is commanded to open tips in the pattern and close tips not in the pattern to dispense the formulation according to the pattern. Valve actuation of individual tips is not limited to circular patterns. In one embodiment, the valve of the tip may be actuated in a linear pattern. Line 914 connects only the tips that will be open to dispense the formulation in a fan pattern, the remaining tips that are not in a linear pattern will be closed. Any combination of individual tips can be selected to ensure that only certain tips dispense formulation and others do not, resulting in distinct patterns.

In one embodiment, dispenser 112 is activated by depressing switch 106 (FIGS. 1 and 2). In one embodiment, the switch 106 is positioned on the upper front surface of the handle 104 so that it can be operated with an index finger. In one embodiment, switch 106 is a momentary switch whose default position is an off position. The momentary switch can dispense a metered amount of agent with just one actuation, regardless of the operating time. Pressing the momentary switch 106 longer does not dispense more agent than the pre-measured amount. In another embodiment, switch 106 is an on-off switch that starts and stops dispenser 112 based on the opening and closing of the switch.

In one embodiment, valves on tips 602, 1702, 1100, 1200 are actuated only when the individual tip selected for dispensing is in contact with the skin. In one embodiment, tips 602, 1702, 1100 and 1200 made of conductive material allow the tips to act as contact sensors. In one embodiment, one of the cylinders of each tip 602, 1702, 1100, 1200 may act as the positive terminal, while a second cylinder of the same or a different tip acts as the negative terminal. In one embodiment, the impedance between any positive terminal of the tip and any negative terminal of the tip may be measured to determine whether one or more individual tips are in contact with the scalp (skin). In one embodiment, the impedance between any positive terminal and the scalp can be measured (via a conductive return path to the handle). Determining impedance and contact is useful if the applicator needs scalp contact: for example, if you are treating the scalp and the device is not working directly on the scalp, there is a risk that the vacuum cleaner will vacuum the hair. Formula treatment and vacuum system.

In one embodiment, impedance measurements can also be used to calculate scalp moisture levels at specific points or over a more general area. In one embodiment, impedance can be measured from different tips to determine scalp moisture levels over a larger area.

In one embodiment, contact sensor 1162 may be disposed at the tip end. In one embodiment, contact sensor 1162 includes an open or short detector or a dielectric sensor. An open detector may mean an open circuit detector for detecting broken (open) continuity in electrical transmission. A short circuit detector may refer to low electrical resistance sensing. Dielectric sensors are also called capacitive sensors that can detect changes in permittivity. In one embodiment, contact sensor 1162 may be a sensor that detects contact or non-contact of individual tips. In one embodiment, the contact sensor 1162 may indicate the amount of contact. An example of a contact sensor capable of detecting the amount of contact is a piezoelectric sensor.

In one embodiment, device 100d includes a massage module 1152 . The massage module 1152 is any circuit configured to control the operation of any number of individual tips 602, 1702, 1100, 1200 to vibrate. In this embodiment, the tips are individually controlled to oscillate compared to the oscillation of the entire brush head. The massage module circuitry may be part of the controller 148 or may be a separate component. The massage module 1152 circuitry controls the individual tips to operate on one to three axes (XYZ). Activation of the tip to vibrate may be initiated by switch 1164. In one embodiment, each tip 602, 1702, 1100, 1200 on the brush head 140 has its own actuator that vibrates each individual tip in one to three axes. In one embodiment, the actuator may include a shape memory or piezoelectric material. As discussed above, the conductive cylinder may be constructed or embedded with a shape memory or piezoelectric material to actuate the vibrations.

Referring to FIG. 20 , one embodiment of a tip 602, 1702, 1100, 1200 includes a first pair of actuators 1008, 1010 disposed on or embedded in the cylinder of the tip at diametrically opposed locations. Actuators 1008 and 1010 extend axially along the length of the tip. Actuators 1008 and 1010 can be actuated one at a time to produce side-to-side motion, such as in the X-axis. The tip includes a second actuator pair actuators 1012 and 1014, which are disposed on or embedded in the cylinders of the tips that are 90 degrees apart from the actuators 1008 and 1010 and diametrically opposed to each other. Actuators 1012 and 1014 extend axially along the length of the tip. Actuators 1012 and 1014 can be actuated one at a time to produce side-to-side motion, such as in the Y-axis. Actuators 1008, 1010, 1012, 1014 are coupled to the conductive substrate of the tip and rely on the transverse piezoelectric effect to produce contraction and bending motion in one direction when a voltage is applied across the piezoelectric material and substrate. In this way, side-to-side operation is possible in both the X and Y axes.

For Z-axis oscillation or up-and-down, the top end of the tip can rest against a shape memory coil 1016 that can be operated to oscillate up and down. Although one embodiment using piezoelectric and shape memory materials is illustrated, other configurations are possible based on the present disclosure. Piezoelectric materials can also be produced or laminated into tubes to cause up-and-down vibration, and shape memory alloys can be provided as strips to cause side-to-side, bending, or shear motion for X- and Y-axis vibration. Any combination of one or more piezoelectric or shape memory alloys can be used to provide a tip that oscillates in one to three axes.

In one embodiment, apparatus 100d includes a vacuum system 114 having a vacuum generating motor and collector 116 . In one embodiment, the motor may be a variable speed motor. The vacuum motor 114 is coupled to an impeller vane that directs an air stream through one of the cylinders of tips 602, 1702, 1100, 1200. A motor directs an air stream through the tip opening. The air stream may carry the used agent along with the oil and debris washed from the hair by the agent, and is captured by the collector 116 and the air exhausted out of the device 100d. In one embodiment, collector 116 includes an annular vent disposed at the back of device 100d. The vent allows the air stream to exit the apparatus 100d while used and debris are trapped in the collector 116.

In one embodiment, the vacuum motor 114 is actuated by a multi-position, multi-function selector switch 110 (FIG. 4). The selection switch 110 may be, for example, a slide switch, a dial switch having two or more positions, or a push button switch having two or more positions. In one embodiment, the vacuum selector switch 110 includes a setting for off and one or more vacuum speed settings such as high and low. In one embodiment, the vacuum switch 110 is located on the lower back of the handle 104 so that it can be operated with the thumb, for example. The vacuum switch 110 can be isolated for uninterrupted vacuum. A light emitting diode 118 can be used to illuminate the selected location. Selector switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch can replace the selector switch, the default position of the momentary switch is the off position, the momentary switch must be depressed to start the vacuum motor. In one embodiment, device 100d includes both a vacuum selector switch and a momentary switch, where the momentary switch activates the vacuum motor when depressed and is used in the speed setting of the selector switch.

In one embodiment, device 100d includes diagnostic module 1160 . The diagnostic module circuitry may be part of the controller 148 or may be a separate module. In one embodiment, the diagnostic module 1160 has circuitry configured to correlate the absorption of specific wavelengths of light with a skin or hair condition. In one embodiment, skin and hair conditions related to hair density, hair density, tone and dryness can be identified by measuring the absorption of light. The diagnosis module 1160 diagnoses skin and hair based on the image of the camera 2158. Camera 2158 may be located at the tip of the tip or on device 100d. In one embodiment, camera 2158 may be a semiconductor integrated circuit that converts light into an image, such as a charge coupled device (CCD) or pixel sensor. In one embodiment, diagnosis of skin and hair conditions is determined by selective filtering, selective absorption of wavelengths within multiple photodetector layers, or any other method. In one embodiment, the spectral absorption characteristic for a given chromophore of skin appears as a dark spot on the image recorded by camera 2158. The absorbance and emission characteristics of the various skin conditions are stored in the controller memory, and the diagnostic module 1160 compares the images to the characteristics representative of the various skin conditions.
