[0002] This application claims the benefit of U.S. Patent Application No. 17 / 035026, filed September 28, 2020, and French Patent Application No. FR 2011808, filed November 18, 2020, the entire contents of which are incorporated herein by reference. Summary of the Invention

[0003] In one embodiment, the brush or comb hair and scalp treatment device has controllable LEDs that emit light in the visible spectrum, or UV (ultraviolet) LEDs or IR (infrared) LEDs or both UV LEDs and IR LEDs embedded in the bristles or tips of the brush, for targeted treatment and information display or pleasing visual effects.

[0004] In one embodiment, the device can turn on LEDs of different wavelengths for use in various hair and scalp treatment applications and for the curing and treatment of various hair and scalp formulations or serums.

[0005] In one embodiment, the scalp and hair treatment device enhances the effectiveness of the treatment by placing an active light component in the area of ​​the device that is in contact with or closest to the target skin, scalp, or hair root area.

[0006] In one embodiment, the ability to generate different colors from emitters arranged in rows and columns with tips is used to display detailed device information, such as charging status, operating mode, cartridge fill level, or pleasing visual effects, by creating RGB pixel-like displays.

[0007] In one embodiment, conductive wiring passes through the hollow bristle tip. Optionally, the bristle tip consists of a conductive spring-like coil. These conductive paths lead to a visible spectrum LED, as well as a UV LED and an IR LED (light-emitting diode), housed within the tip. These components are encapsulated and sealed with a transparent cap. The LEDs are controlled by signals along these conductive paths. These signals are driven by controller circuitry housed within the body of the device.

[0008] In one embodiment, the device folds itself. When the device is in the folded configuration, the LED is located behind the diffuser, and the visual effect produced by the LED can be more clearly perceived because the visual gap between the LED and the tip can be filled with the diffuser material.

[0009] In one embodiment, the brush or comb hair and scalp treatment device has a controllable electromagnetic energy emitter configured to emit light in the visible spectrum, or a UV (ultraviolet) LED, or an IR (infrared) LED, or both UV and IR LEDs.

[0024] Individuals are washing their hair less frequently with traditional wet-based shampoos. Several reasons could explain this decline, such as preventing hair loss and damage or saving time and effort. Dry shampoos are on the rise. People are trying to extend the time between salon visits to save money, leading to increasing interest in tinted dry shampoos for root touch-ups. Dry shampoos are primarily packaged in spray bottles. However, spray bottles present problems with inhaling the product and accidentally spraying it into the face (especially the eyes). Spray bottles are inaccurate in terms of spray direction and volume. Furthermore, they are unsuitable for travel or use of public restrooms. Dry shampoos do not cleanse the scalp and can actually damage it. Despite this, people believe that scalp care leads to healthy hair. The "dry" method of scalp cleansing involves brushing or combing to apply oils to the hair. Scalp care and scalp-guided formulas can be applied via pipette, foam, or powder and require manual parting of your hair. Powders and foams are handled by hand. Applying excessive amounts of product to the scalp can cause hair loss and oily-looking hair. Reusable and closed-loop product designs are in ever-growing demand.

[0025] A hair and scalp treatment device for brushes or combs with a controllable electromagnetic energy emitter is disclosed, which is configured to emit light in the visible spectrum, or a UV (ultraviolet) LED, or an IR (infrared) LED, or both UV LED and IR LED. Non-limiting examples of the electromagnetic energy emitter include: arc flash lamps, continuous wave bulbs, incandescent lamp emitters, laser diodes, light-emitting diodes (e.g., high-efficiency UV light-emitting diodes, microcavity light-emitting diodes, organic light-emitting diodes, polymer light-emitting diodes, polymer phosphorescent light-emitting diodes, etc.), light energy emitters, quantum dots, etc.

[0026] refer to Figures 1 to 3 The hair and treatment device 100 includes controllable LEDs embedded in brush heads 602, 702, 1100, and 1200 for targeted treatment and information display or pleasing visual effects. Although the illustrations depict a brush embodiment, the tips may be arranged in a comb embodiment, i.e., arranged in a single row of tips.

[0027] In one embodiment, device 100 selectively turns on LEDs of different wavelengths for various hair and scalp treatment applications and for the curing and treatment of various hair and scalp formulations or serums. Device 100 can control the rate at which the LEDs are turned on and off, as well as the brightness and intensity of each LED at its respective wavelength.

[0028] In one embodiment, the scalp and hair treatment device 100 enhances the effectiveness of such treatment by placing an active light component in the area of ​​the device 100 that is in contact with or closest to the target skin, scalp, or hair root area. In one embodiment, the active light component is placed at the tip of a pointed end.

[0029] In one embodiment, the scalp and hair treatment device 100 uses LEDs that emit light within the visible spectrum to produce different colors at the tips. Visible color LED emitters placed on the tips arranged in rows or columns are used to display detailed device information, such as charging status, operating mode, box level, or pleasing visual effects, by creating an RGB pixel-like display. RGB (red-green-blue) LEDs are used as representative examples of LEDs emitting light within the visible spectrum to demonstrate aspects of this disclosure, and other LEDs emitting light within the visible spectrum can be used instead of RGB LEDs.

[0030] In one embodiment, conductive wiring passes through the hollow bristle tip. Optionally, the bristle tip consists of a conductive spring-like coil. These conductive paths lead to a visible spectrum LED, as well as a UV LED and an IR LED (light-emitting diode) within the tip. These components are encapsulated and sealed with a transparent cap. The LEDs are controlled by signals along these conductive paths. These signals are driven by controller circuitry housed within the body of the device 100.

[0031] In one embodiment, the device 100 folds itself. When the device 100 is in the folded configuration, the LED is located behind the diffuser, and the visual effect produced by the LED can be more clearly recognized because the visual gap between the LED and the tip can be filled with the diffuser material.

[0032] refer to Figures 1 to 3In one embodiment, device 100 includes a handle 104 attached to a generally cylindrical portion 138. This portion 138 may have a circular cross-section or have any other shape, such as a rectangle, square, or a combination of shapes. The handle 104 is attached to device 100 at an obtuse angle relative to the front end of device 100. The handle 104 helps to balance the weight of the device for more comfortable use and easier control. Control buttons may also be located on the handle.

[0033] In one embodiment, the device 100 includes a main structure having a generally cylindrical portion 138 extending from a rear end on which a cylinder 102 is mounted to a front end on which a brush head 140 is located. In one embodiment, a handle 104 is attached to the rear side of the cylindrical portion 138.

[0034] Brush head 140 is part of device 100 that holds tips 602, 702, 1100, or 1200. In one embodiment, device 100 has tips 602, 702, 1100, 1200 arranged in a brush configuration (e.g., concentric circles). In one embodiment, the tips are also configured to control the dispensing of formulation from selected individual tips rather than other tips. This allows some tips to be “on” while others are “off” to create a different spray pattern than brush head 140. Similarly, for visible chromatography as well as UV and IR LEDs, the LEDs of the tips are individually turned on and off, so some tips may be lit in color while others are not.

[0035] In one embodiment, the handle 104 is pivotally connected to the cylindrical portion 138. In this way, when not in use, the cylindrical portion 138 can be folded inside the handle 104.

[0036] exist Figure 1 The image shows a device 100, which includes a cylindrical portion 138 with a brush head 140 at the end in an extended position, making the device operable. Figure 2 The device 100 is shown from the front, illustrating that it may include a chamber 142 within a handle 104. Figure 3 The image shows a device 100 in which the cylindrical portion 138 and the brush head 140 are in a folded position, wherein the cylindrical portion 138 and the brush head 140 are retracted into the handle 104 and stop in the chamber 142.

[0037] In one embodiment, in the folded position, the tips 602, 702, 1100, and 1200 are positioned near the diffuser material 136. The diffuser material 136 is located at the end of the handle 104 and has an outer surface so that it is visible from the outside, i.e., visible by looking down at the end of the handle 104. The tips point in the direction of the diffuser material 136. The diffuser material 136 is either completely transparent or translucent to light, or has a degree of opacity but is not completely opaque, allowing some light emitted by the tips to be visible from the outside of the diffuser material 136. In one embodiment, the diffuser material 136 produces a softer light by scattering the emitted light to fill the gaps between the tips.

[0038] In one embodiment, device 100 includes a housing that receives a removable cartridge 102 containing a hair or scalp treatment formulation. Device 100 allows the cartridge 102 to be easily interchanged to provide different formulations. The cartridge 102 can be configured as a refillable cartridge or a disposable cartridge. In one embodiment, device 100 can be configured to accommodate more than one cartridge 102, wherein each cartridge can be filled with a different formulation for a different treatment. Optionally, some applications may use two or more different formulations, requiring the application of two formulations to achieve the desired treatment.

[0039] In one embodiment, tips 602, 702, 1100, and 1200 are configured to dispense two different formulations. In one embodiment, tips 602, 702, 1100, and 1200 have cavities extending the entire length of the tip. Tips 602, 702, 1100, and 1200 are at least one diameter in length. However, tips 602, 702, 1100, and 1200 can be constructed to have several diameters in length, so the width-to-length ratio can range from 1:1 to 1:20 or more. Tips 602, 702, 1100, and 1200 can be flexible or non-flexible. Tips 602, 702, 1100, and 1200 can also be attached to the brush head 140 with a flexible material. Separation chambers in the tips allow one or more formulations to be delivered through each chamber without mixing. The formulations can be separated within the respective chambers until they exit the chamber. Dispensing of the formulation can be achieved by configuring each chamber to have an opening along the length of the chamber, or only at the end of the chamber, or both along the length of the chamber and at the end. Furthermore, each chamber in the tip may have a valve or other device to control dispensing from only one chamber or both chambers. Controlling the dispensing of the formulation from only certain tips on the brush head 140 enables the generation of multiple patterns for dispensing, such as conical sprays, fan sprays, etc.

[0040] In one embodiment, the chamber is depicted as a semi-cylinder and a full cylinder, but the chamber can have any cross-sectional shape. Furthermore, in one embodiment, the tips 602, 702, 1100, 1200, and the first and second cavities forming them can be conductive, thus being configured as positive and negative terminals to further provide microcurrents or to the scalp and hair. Additionally, the conductive tips 602, 702, 1100, 1200 have other uses when the first and second cavities are connected to the positive and negative terminals of a power source or when the first and second cavities are connected to a positive sensing terminal and a negative sensing terminal.

[0041] In one embodiment, the tips 602, 702, 1100, and 1200 do not need to be conductive, but the multi-column structure is still useful if the application involves mixing or dispensing a formulation and evacuating it to a small, controlled target area on the scalp.

[0042] refer to Figure 4 In one embodiment, the tip 602 is configured to connect the first hollow semi-cylinder 604 to the second hollow semi-cylinder 606 along its length. The first semi-cylinder 604 and the second semi-cylinder 606 may be made of a conductive material. In one embodiment, the first semi-cylinder 604 and the second semi-cylinder 606 are separated by an electrical insulator 608. Here, although the overall shape of the tip 602 is "cylinder", according to this disclosure, the tip 602 may have any cross-sectional shape, including elliptical, rectangular, square, or any other polygon.

[0043] In one embodiment, the first hollow half-cylinder 604 and the second hollow half-cylinder 606 are made of a conductive material such as metal. In one embodiment, one of the first half-cylinder 604 or the second half-cylinder 606 may be designated as a positive conductor terminal, and the other as a negative conductor terminal.

[0044] In one embodiment, the first cavity 604 and the second cavity 606 may be made of shape memory material or piezoelectric material, or the first cavity 604 and the second cavity 606 may be embedded with shape memory material or piezoelectric material, which can be actuated by an electric current to control the direction of movement of the tip 602. In one embodiment, the chambers in the dual-chamber structure may be made of or embedded with shape memory material or piezoelectric material, actuated in opposite directions, allowing positive and / or negative actuation around a central position depending on which chamber is actuated. For example, these materials may be in the form of polymers, ceramics, and alloys. In one embodiment, the shape memory material and piezoelectric material may be fabricated as coils and do not necessarily have to be cavities. The coils can effectively actuate the tip perpendicularly along the Z-axis (i.e., in the axial direction of the coil). Electrical actuation of the shape memory material and piezoelectric material is performed via an AC or DC power supply having positive and negative terminals connected to the shape memory material or piezoelectric material.

[0045] Figure 4 It is further explained that the tip 602 may have an opening 904 on its outer periphery. The hollow semi-cylinder 604 has a first opening 904 along its outer length, and the hollow semi-cylinder 606 has a second opening 906 along its outer length. In one embodiment, the openings 904 and 906 may be formed by laser-cutting holes (perforations) along the length of the tip 602.

[0046] In one embodiment, the tip 602 may omit the opening along its length, and the tip 602 may have an opening only at its end for use in treating the scalp. In this way, two different formulations can be delivered from the tip 602 via the hemispheres 604 and 606.

[0047] In one embodiment, the end of tip 602 includes a perforated flat or dome-shaped disc having a small opening 610 in the first hemi-cylinder 604 and an opening 612 in the second hemi-cylinder 606. In one embodiment, instead of a disc, hemi-cylinders 604 and 606 may be fully open at their ends. Either configuration allows for dispensing of formulations from the end or along the length of tip 602, or along both the length and end of tip 602.

[0048] refer to Figure 5In one embodiment, the tip 702 is constructed by inserting a first hollow, small-diameter cylinder 704 into a second hollow, large-diameter cylinder 706. In one embodiment, the first cylinder 704 and the second cylinder 706 are coaxial. The first cylinder 704 may be referred to as the inner cylinder, and the second cylinder 706 may be referred to as the outer cylinder. Here, although the tip 702 is in the shape of a "cylinder," according to this disclosure, the tip may have any cross-sectional shape, including elliptical, rectangular, square, or any other polygon.

[0049] In one embodiment, the first pillar 704 and the second pillar 706 are made of a conductive material such as metal. In one embodiment, the exterior of the first smaller pillar 704 may be coated with an insulator. An insulator is optional if the first pillar 704 and the second pillar 706 are not electrically insulated from each other. In one embodiment, one of the first pillar 704 or the second pillar 706 will be designated as a positive conductor terminal, and the other will be designated as a negative conductor terminal.

[0050] In one embodiment, the first cavity 704 and the second cavity 706 are made of, or may be embedded in, a shape memory material or piezoelectric material, which can be actuated by an electric current to control the direction of movement of the tip 702. In one embodiment, the chambers in the dual-chamber structure can be made of, or embedded in, actuated in opposite directions, allowing positive and / or negative actuation around a central position depending on which chamber is actuated. For example, these materials can be in the form of polymers, ceramics, and alloys. In one embodiment, the shape memory material and piezoelectric material can be fabricated as coils and do not necessarily have to be cavities. The coils can effectively actuate the tip perpendicularly along the Z-axis (i.e., in the axial direction of the coil). Electrical actuation of the shape memory material and piezoelectric material is performed via an AC or DC power supply having positive and negative terminals connected to the shape memory material or piezoelectric material.

[0051] exist Figure 5In this configuration, the inner pillar 704 has a first opening 1004 appearing on the exterior of the outer pillar 706; however, the opening 1004 can be connected through the outer pillar 706 such that the opening is closed to the outer pillar 706, for example, through a tube leading to the inner pillar 704. The outer pillar 706 has a second opening 1006 along its outer length, wherein the opening 1006 connects only to the interior of the outer pillar 706. In one embodiment, the inner pillar 704 and the outer pillar 706 are not coaxial with each other, but the inner pillar 704 can be positioned against the inner wall of the outer pillar 706, so that the opening from the inner pillar 704 may only need to pass through the wall of the outer pillar 706, thus avoiding the need for a tube connecting the opening. An insulator may be needed between the inner pillar 704 and the outer pillar 706 for electrical insulation. In either configuration, two different formulations can be delivered from the tip 702 via the inner pillar 704 and the outer pillar 706. In one embodiment, openings 1004, 1006 can be formed by laser cutting holes (perforations) along the length of tip 702.

[0052] In one embodiment, the end of tip 702 includes a perforated flat or dome-shaped disc having a small opening 710 in a first inner column 704 and an opening 708 in a second outer column 706. In one embodiment, instead of a disc, the inner column 704 and outer column 706 may be fully open at the end. Either configuration allows for dispensing of formulations from the end or along the length of tip 702, or along both the length of the tip and the end.

[0053] In one embodiment, when tips 602 and 702 are made of a conductive material, one of the pillars 604 or 606 and 704 or 706 of each tip 602 or 702 can be used as a positive terminal, while the other can act as a negative terminal for conducting electrical charge. This allows for powering devices such as LEDs or sensors.

[0054] Figure 6 A tip 1100 is shown, structurally similar to tip 602, comprising a conductive second hollow half-cylinder 1106 formed by two electrically insulating but side-by-side conductive first hollow half-cylinders 1104, wherein the first half-cylinder 1103 is designated as positive and negative terminals, and the second half-cylinder 1106 is a terminal with the opposite polarity to the first half-cylinder 1104. An electrically insulating material or coating may be added between the first and second hollow half-cylinders 1104 for electrical insulation. A power source is connected to the first and second half-cylinders 1104. In one embodiment, this allows one or more light-emitting diodes 1102 to be placed at the end of the tip or at other locations where the two half-cylinders, serving as terminals, are powered through contact with the positive and negative terminals.

[0055] Figure 7A tip 1200, structurally similar to tip 702, is shown. It is made of a conductive first hollow inner pillar 1204, which is placed within or coaxially within a conductive second hollow outer pillar 1206. The first inner pillar 1204 is a positive or negative terminal, and the second outer pillar 1206 is a terminal with the opposite polarity to the first pillar 1204. An electrically insulating material or coating may be added between the first and second hollow pillars 1204 for electrical insulation. A power source is connected to the first inner pillar 1204 and the second outer pillar 1206. In one embodiment, this allows one or more light-emitting diodes 1202 to be placed at the end of the tip or at other locations where the two pillars, serving as terminals, are powered by contact with positive and negative terminals.

[0056] In one embodiment, depending on the power of LEDs 1102 and 1202, heat dissipation can be absorbed (heat dissipation) by the conductive material of pillars 1104, 1106, 1204 and 1206.

[0057] In one embodiment, when LEDs 1102 and 1202 are placed at the tip of the tip, the LEDs can deliver more energy to the scalp compared to when they are placed at the bottom of the tip or when the LED light is transmitted through a long optical fiber path.

[0058] In one embodiment, LEDs 1102 and 1202 can be used for treatment, curing formulation, or indicating device status (i.e., operating mode or charging status).

[0059] The LED can be any type of single-wavelength (laser LED) or a range of wavelengths. In one embodiment, phototherapy has been used on the scalp to treat skin conditions. In another embodiment, phototherapy has been used to stimulate hair follicle cells. For example, the intensity of the light generated by LEDs 1102 and 1202 can be changed by controlling the current.

[0060] In one embodiment, LEDs 1102 and 1202 comprise one or more group III-V (GaAs)-based LEDs capable of emitting electromagnetic radiation with wavelengths ranging from green visible light to near-infrared. In another embodiment, LEDs 1102 and 1202 comprise one or more group III nitride blue LED solid-state emitters capable of emitting electromagnetic radiation with wavelengths ranging from ultraviolet to blue visible light.

[0061] In one embodiment, the wavelength output of LEDs 1102 and 1202 comprises one or more gallium indium nitride (GaInN) LEDs having a wavelength output of approximately 360 nm to 370 nm. In other embodiments, LEDs 1102 and 1202 emit electromagnetic energy in a wavelength range from approximately 200 nm to approximately 2000 nm, including wavelengths in the ultraviolet range (approximately 350 nm) and near-infrared range (approximately 1200 nm).

[0062] refer to Figure 10 An embodiment of the arrangement of LED 200 that can be used with tips 602 and 702 is shown. Figure 10 As shown, when tips 602 and 702 are equipped with LEDs, the dispensing openings on the ends of tips 602 and 704 may be omitted. In one embodiment, tips 602 and 702 include at least one visible spectrum LED, such as an RGB (red-green-blue) LED 202 and / or at least one UV or IR LED 204, or both UV and IR. Although the RGB LED is used as a representative example to illustrate aspects of this disclosure, other LEDs emitting light within the visible spectrum may be used instead of the RGB LED 202. The visible spectrum of the electromagnetic radiation spectrum is generally considered to be from approximately 380 nm (violet) to approximately 740 nm (red).

[0063] In one embodiment, the RGB LED generates three nominal wavelengths, which are selected to maximize the range of perceived colors by varying their intensity. The RGB LED 202 may include three LEDs in a single package, one for each of the red, green, and blue colors. In one embodiment, the red light has a wavelength of approximately 620 nm to 750 nm, the green light has a wavelength of approximately 495 nm to 570 nm, and the blue light has a wavelength of approximately 450 nm to 495 nm. In one embodiment, the RGB LED 202 includes wiring for a common cathode and three anodes, with one anode corresponding to each of the red, green, and blue LEDs. In another embodiment, the RGB LED 202 includes wiring for a common anode and three cathodes. Figure 12This is a schematic diagram of an embodiment of a tip 1300 having an LED structure 200 at its end. Tip 1300 can be used in place of tip structures 602 and 702. In one embodiment, for example, tip 1300 is configured as a spring-like coil having a plurality (four) of conductive wires 1302, 1304, 1306, 1308 to control RGB LED 202. In one embodiment, the voltage of each of the red, green, and blue LEDs is independently modulated to turn on and change the intensity of one or more LEDs in the RGB LED 202. The red, green, and blue LEDs are used to produce any color composed of two or more colors.

[0064] In one embodiment, RGB and UV or IR LEDs 202, 204 are encapsulated and sealed with a light-transparent cap 208, such as epoxy resin. LEDs 202 and 204 are controlled via signals along conductive wiring paths 206 and 210, such as the pillar itself or dedicated wiring, considering that RGB LEDs require different signals for each of the red, green, and blue LEDs. The signals powering LEDs 202 and 204 are driven by a light controller circuitry housed within the body of the device.

[0065] refer to Figure 8 The device 100 is schematically shown to illustrate the main system.

[0066] In one embodiment, device 100 includes a power supply 128. Device 100 can be powered by alternating current (AC) or direct current (DC). In one embodiment, device 100 is powered by common household AC power, which supplies power to device 100 via a wire (not shown). In another embodiment, device 100 is powered by direct current, such as a rechargeable battery that can be charged by plugging into a household AC outlet. DC-powered device 100 allows use of the device without needing to be near or near an electrical outlet. Power supply 128 is configured to provide power to any system that requires power, such as controller 148, distributor 112, optical module 152, vacuum motor 114, camera 160, LEDs 1102, 1202, and tips 602, 702, 1100, and 1200.

[0067] In one embodiment, device 100 includes a formulation dispenser 112. In one embodiment, the formulation is stored in a replaceable or refillable cartridge 102. The cartridge 102 can be removed from device 100 for refilling or disposal and replacement with a new, complete cartridge. Once emptied, 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. Figure 1As shown, the tube 102 is inserted through the back of the device 100. The tube 102 is connected to supply scalp or hair preparations to the dispenser 112. In one embodiment, the device 100 may hold multiple tubes, each filled with a different preparation that can be dispensed to achieve different treatments and for different areas of the scalp and hair.

[0068] In one embodiment, the cylinder 102 has a product identification tag that can transmit operating instructions for the device 100 based on a specific formulation contained in the cylinder 102. The device 100 may include a product identification tag reader capable of reading the product identification tag and processing the encoded signal into instructions for operation and control of the device based on the specific formulation. The product identification tag includes, for example, barcodes, 2-D barcodes, RFID, etc. The product identification tag is encoded with a machine-readable signal that conveys a device setup for a specific formulation. Different formulations may have different device setups. For example, the product identification tag may include dispenser setups ranging from liquid to fine droplets, medium droplets, or coarse droplets. The product identification tag may also include dispenser pattern formation, such as flat fan vs. cone, wide vs. narrow, solid vs. hollow, flow vs. mist. The product identification tag may also contain instructions for operating LEDs 202, 204, 1102, and 1202. Different formulations may also be used to treat different areas of the scalp and hair. Different formulations may also be used to provide different treatments for the scalp and hair.

[0069] Dispenser 112 can dispense one or more formulations in the form of a fine mist, liquid, or any combination thereof via tips 602, 702, 1100, 1200. In one embodiment, dispenser 112 includes a compressor, pump, or ultrasonic generator to generate a mist from the formulation. In the case of a pump or compressor dispenser 112, such dispenser 112 causes air or formulation to flow at a high speed, thereby forcing the formulation through a fine opening. In the case of a pump or compressor dispenser, a single dispenser 112 may be placed in device 100. The outlet of the compressor or pump dispenser 112 is then guided to each individual tip via a system of conduits.

[0070] In one embodiment, dispenser 112 is an ultrasonic atomizer that generates a mist or vapor to dispense the formulation through individual tips. This has the advantage of gentle dispersion of the formulation, reducing waste and improving control of coverage. In one embodiment, the atomizer uses an ultrasonic generator that contacts the formulation, wherein the frequency of the ultrasound is sufficient to produce a mist. The ultrasonic atomizer also includes a “grid” atomizer, which has a vibrating grid that just contacts the surface of the formulation to produce a mist. Piezoelectric elements can be used in any form of ultrasonic atomizer.

[0071] In one embodiment, both the ultrasonic generator and the vibrating mesh jet can use piezoelectric materials to generate vibrations at ultrasonic frequencies. In one embodiment, the same piezoelectric material used in the jet can also be used to drive the tactile system. The tactile system can include a massage therapy system, but can also include any system that provides a sensory experience, such as heating and associated ultrasonic therapy. The atomizer may rely on generating frequencies exceeding 1 MHz. Jettors capable of generating frequencies exceeding 1 MHz can also be used to drive the tactile system to generate heat, which can be used to treat the skin and scalp individually or in conjunction with the dispensing of a formulation. Some jets may also rely on ultrasonic frequencies less than 1 MHz. In one embodiment, the jet can be used to drive the tactile system to generate a range of frequencies designed to deliver a therapeutic compound to the skin and scalp in conjunction with the dispensing of a formulation. Therefore, there are advantages when the same piezoelectric material used in the jet system is used in the tactile system.

[0072] In one embodiment, each tip may include a valve at the inlet of one or both chambers. The valve has an actuator for opening and closing. Each valve at each tip can be actuated to open or close independently of other valves at other tips. By opening or closing the valve at each individual tip, the formulation can be controlled to flow out only from selected tips in a controlled pattern, such as conical, flat fan-shaped, stream, multiple streams, pulse, etc. Furthermore, valves controlling the dispensing from the two chambers of the tip allow for controlled outflow of the formulation from one or both chambers.

[0073] Figure 9 This is a schematic diagram of the ends of tips 602, 702, 1100, and 1200. The term "end" can be used to indicate an orthogonal direction relative to the length of the tip, or it can refer to a length close to the orthogonal direction, such as along a length near the orthogonal direction. In one embodiment, the tips are arranged in an increasing diameter circular pattern of a small diameter 908, a medium diameter 910, and a large diameter 912. In one embodiment, only the valve of the tip connected to one of the circles 908, 910, or 912 can be opened, resulting in the dispensing of formulation in the small cone 908, medium cone 910, and large cone 912 to cover small, medium, and large areas of the scalp or hair. The controller is instructed to open the tips located in the pattern to dispense formulation according to the pattern and to close the tips not located in the pattern. Actuation of the valves of individual tips is not limited to the circular pattern. In one embodiment, the valves of the tips can be actuated in a linear pattern. Line 914 links only the tips that will be opened to dispense formulation in a fan-shaped pattern, while the remaining tips not in the linear pattern remain closed. Any combination of individual tips can be selected to dispense the formulation from some tips rather than others to achieve different modalities.

[0074] In one embodiment, dispenser 112 is operated by pressing switch 106. In one embodiment, switch 106 is a momentary switch whose default position is off. The momentary switch only needs to be activated once, regardless of the duration of activation, to dispense a measured amount of formulation. Holding the momentary switch 106 down for a longer period will not dispense more formulation than the pre-measured amount. In another embodiment, switch 106 is an on / off switch that activates and deactivates dispenser 112.

[0075] In one embodiment, valves on tips 602, 702, 1100, and 1200 are actuated only if the individual tip selected for dispensing contacts the skin. In one embodiment, tips 602, 702, 1100, and 1200, made of conductive material, allow the tips to function as contact sensors. In one embodiment, one of the pillars in each tip 602, 702, 1100, and 1200 can be used as a positive terminal, while a second pillar of the same or different tip serves as a negative terminal. In one embodiment, the impedance between any positive terminal and any negative terminal of the tip can 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 (processed via a conductive return path) / determining the impedance and contact is useful if the application requires scalp contact; for example, in formulation therapy and vacuum systems, the scalp is being treated, and vacuuming risks hair removal if the device does not operate directly on the scalp.

[0076] In one embodiment, impedance measurements can also be used to calculate scalp moisture levels 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 wider area.

[0077] In one embodiment, the contact sensor 162 may be placed at the tip. In one embodiment, the contact sensor 162 includes an open-circuit or short-circuit detector or a dielectric sensor. An open-circuit detector may refer to an open-circuit detector used to detect interruptions (open circuits) in the continuity of electrical transmission. A short-circuit detector may refer to a low-resistance detector. A dielectric sensor, also known as a capacitance detector, can detect changes in the dielectric constant. In one embodiment, the contact sensor 162 may be a sensor that detects contact or non-contact of a single tip. In one embodiment, the contact sensor 162 may indicate the amount of contact. An example of a contact sensor that can detect the amount of contact is a piezoelectric sensor.

[0078] In one embodiment, device 100 includes an optical module 152. The optical module 152 has circuitry configured to control LEDs 202, 204, 1102, and 1202 at the tip. In one embodiment, the optical module 152 has circuitry configured to control which LEDs are turned on and off, the rate at which they are turned on and off, and the brightness and / or intensity of each LED at its respective wavelength. The circuitry of the optical module 152 may be included within or separate from the controller 148. Specifically, referring to RGB LED 202, the optical module 152 has circuitry configured to control the on / off state and to vary the intensity of red, green, and blue light emitted from each RGB LED 202. By turning on and varying the intensity of the individual red, green, and blue LEDs of the RGB LED 202, many different colors can be individually produced from the tip, with some tips being illuminated to produce a specific color and others being illuminated differently.

[0079] Figure 11 Views of the ends of tips 602 and 702 are shown, each tip having an RGB LED 202 mounted at its end. The term "end" can be used to indicate an orthogonal direction relative to the length of the tip, or it can refer to a length near the orthogonal direction, such as along a length close to the orthogonal direction. In the example shown, the light module 152 turns on the red LED of the outer circle of the tip, turns on the red and green LEDs of the middle circle of the tip, which combine to give a yellow hue, and turns on the green LED of the inner circle of the tip. In one embodiment, the RGB LEDs 202 at the tip can be controlled by combining any two or more of the red, green, and blue LEDs to give any color of red, green, or blue, or a certain color. Multiple colors of shading can be achieved at each tip by individually turning on and changing the intensity of each red, green, and blue LED. Each tip can be lit to give the same color, or different tips can be lit to give different colors. Furthermore, the ability to individually control the light emitted from each tip allows for the creation of alphanumeric characters, such as numbers and letters spelled out by only lighting certain tips. Individual tips with RGB LEDs can be lit in different colors to represent different patterns. By using different colors or specific lighting tips, RGB LED 202 can be used to display detailed device information, such as charging status, operating mode, box level, or pleasing visual effects, by creating an RGB pixel-like display. In one embodiment, when device 100 is in the off position ( Figure 3The RGB LED 202 operates to indicate status or provide a visual display. In the off position, the light emitted by the RGB LED is visible through the diffuser 136, which can scatter the light to fill the gap between the tips, providing a pleasing visual effect and offering useful device status information.

[0080] In one embodiment, device 100 includes a vacuum system 114 having a vacuum generating motor and a collector 116. In one embodiment, the motor may be a variable speed motor. The vacuum motor 114 is connected to impeller blades that allow airflow to enter through one of the cylinders at tips 602, 702, 1100, and 1200. The motor directs the airflow through the tip openings. The airflow may carry used formulations and any debris and oil washed out of the hair by the formulations, which are then captured by the collector 116, and the air is expelled from device 100. In one embodiment, the collector 116 includes an annular vent located at the rear of device 100. The vent allows airflow to exit device 100 while used and debris are captured in the collector 116.

[0081] In one embodiment, the vacuum motor 114 is operated by a multi-position, multi-functional selector switch 110. For example, the selector switch 110 may be a slide switch or dial switch with two or more positions, or a push-button switch with 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 positioned on the rear side of the lower portion of the handle 104, for example, to allow operation with the thumb. The vacuum switch 110 may be isolated for uninterrupted vacuum. The selector switch 110 remains in the selected position until it is moved to another position. In one embodiment, a momentary switch may replace the selector switch, wherein the default position of the momentary switch is the off position, and the momentary switch must be pressed to start the vacuum motor. In one embodiment, the device 100 includes both a vacuum selector switch and a momentary switch, wherein the momentary switch is used to operate the vacuum motor when pressed and at the speed setting on the selector switch.

[0082] In one embodiment, device 100 includes a controller 148. In one embodiment, controller 148 is a digital device.

Memory is any type of computer-readable medium or computer storage device that can be accessed and used by one or more microprocessors to execute instructions. Instructions can be stored in high-speed memory, such as EEPROM, flash memory, RAM, or other programmable non-volatile memory.

[0084] The controller 148 communicates with the distributor 112, the optical module 152, and the vacuum 114 to make decisions and control the output from the device 100 based on inputs received from the tips 602, 702, 1100, 1200 themselves, the LEDs 202, 204, 1102, 1202, and / or the contact sensor 162.

[0085] In one embodiment, controller 148 is configured to turn on and off and change the intensity of light from individual LEDs emitting light within the visible spectrum, such that the color of light emitted from each individual tip can be different.

Controller 148 may control the opening and closing of all tips 602, 702, 1100, and 1200 to allow formulations to be dispensed in a pattern via individually selected tips.

[0087] In one embodiment, the controller 148 has circuitry for determining the impedance between the terminals of any one or more tips to determine which tips are in contact with the skin and which tips are not. The controller 148 can then open the valves on the contacting tips and close the valves on the non-contacting tips, allowing the dispenser to continue dispensing the formulation through the tips in contact with the skin.

[0088] In one embodiment, controller 148 has circuitry for determining the impedance between terminals of any one or more tips to determine which tips are in contact with or near the skin, and which tips are not in contact with the skin. Controller 148 can then turn on only those LEDs of the tips that are in contact with or near the skin.

[0089] In one embodiment, controller 148 uses impedance to determine whether the tip is in contact with the scalp. In one embodiment, when it is determined that one or more tips are not in contact with the scalp, controller 148 may shut off vacuum 14 or prevent vacuum from being turned on.

Controller 148 has instructions for the wavelength to be used and the power to be applied for phototherapy, and then supplies power to the LEDs at the appropriate wavelength.

[0096] In one embodiment, the controller 148 has circuitry that controls the amount of formulation dispensed by the dispenser 112. For example, the controller 148 may turn on a pump or compressor for a predetermined amount of time associated with a specific quantity of formulation.
