Description

Nail product curing system and methods for curing nail products

This disclosure relates to a curing system for nail products, and to a system and method for curing light-curable nail products onto the hands or feet of a user.

Nail product curing systems are used in the beauty industry to cure light-curable nail products. For example, fingernails and toenails can be coated with light-curable nail products such as nail polish, ultraviolet (UV) curable nail gel, and artificial nails. Nail products may contain a combination of photoinitiators and selected polymers. The photoinitiator reacts with light to form free radical photoinitiators, which then react with the polymer to form a nail coating. This process is referred to in the art as curing nail products.

Nail product curing systems may include a nail lamp for curing nail products to the appropriate position on a user's nails. These nail lamps typically include an opening for positioning the user's appendage (i.e., hand or foot) within the nail treatment space. U.S. Patents 9,855,543; 10,247,475; 10,357,094; and 11,641,919 disclose exemplary prior art nail lamps. These nail lamps are designed for nail service providers (such as beauty salons) and home nail product users. However, conventional prior art nail lamps have several problems and drawbacks.

One problem with traditional nail lamps is that the light source is typically composed of UV tubes or bulbs, which do not produce light with uniform brightness. Furthermore, UV tubes or bulbs generate excessive radiant energy and heat. This radiant energy can heat the user's hands or feet, causing discomfort. Some nail lamps have fans to cool the light source or circuitry, not the user. Traditional nail lamps may have multiple buttons on the main body. These buttons are designed to control curing time, curing parameters, intensity, curing start, and curing stop. However, touching the buttons with your fingers can easily contaminate them with nail products. Additionally, if nail products cover the buttons or enter the gaps between them, they can be difficult to clean, especially after curing.

Another issue is that the process of applying nail products may involve a base coat, a middle coat, and multiple color coats for each nail. Users may need to place their hands or feet into the nail lamp's chamber multiple times, which is very time-consuming and requires effort and patience. Some products require each nail to be applied separately from the base coat to the color coat, which will require the user to place their hands or feet into the chamber even more times.

This disclosure relates to a nail product curing system and method designed to overcome some of the problems associated with conventional nail lamp curing systems. As the description proceeds, other objectives, advantages, and capabilities of this system and method will become more apparent.

A nail curing system for curing nail products includes a housing having a nail treatment space configured to receive one or more nails of a user for a curing process. The nail product curing system also includes multiple LED light sources for generating light within the nail treatment space. The LED light sources may include light-emitting diodes (LEDs) configured to emit light of a specific wavelength (e.g., white light, colored light, UV light, blue light, or IR light). The LED light sources may also include short-wave ultraviolet (UVC) light-emitting diodes for disinfecting the nail treatment space and other components of the system.

The nail product curing system may also include a light blocker on the casing to prevent light from escaping from the nail treatment space; a display panel on the casing for displaying information; and a handle on the casing for transport. The nail product curing system may also include external LED lights on the casing, configured to allow inspection and curing of nail products outside the nail treatment space, and to disinfect the nail treatment space using UVC. The nail product curing system may also include a base for the casing, which may optionally include control buttons, a display panel, and a battery pack. The nail product curing system may also include a cooling system located on the casing or base, configured to cool the nail treatment space.

The nail product curing system also includes a sensing and control system comprising multiple non-contact sensors on the casing and within the nail processing space, configured to sense the placement of the user's hand and nails within the processing space. The non-contact sensors can also be configured to control various parameters of the curing process, such as start, stop, formula, temperature, and LED power, based on the user's hand movements. The sensing and control system also includes a circuit board on the casing that electrically communicates with the non-contact sensors and is configured to control the LED light source and curing process using inputs and programmed instructions from the non-contact sensors. The sensing and control system further includes a wireless transmission controller that communicates with the circuit board, acting as a remote controller (or remote control) for controlling the curing process. The sensing and control system allows users to control the curing process without touching any buttons.

A method for curing a nail product includes the following steps: providing a nail product curing system, the system comprising a housing having a nail processing space configured to accommodate a user's hand and one or more nails for a curing process; one or more LED light sources on the housing for generating light within the nail processing space; and a sensing and control system on the housing having multiple non-contact sensors configured to sense the placement of the user's hand and nails within the nail processing space, and to control the LED light sources and the curing process via sensor inputs, user hand movements, and programmed instructions. The method further includes the steps of: placing a hand in the nail processing space, sensing the hand placement using the sensing and control system, and controlling the curing process using the sensing and control system.

Referring to Figures 1A, 1B, 2, and 2A, a nail product curing system 10 (Figure 1A) is illustrated for curing nail product 17 (Figure 2A). As shown in Figure 1A, the nail product curing system 10 includes a shell 12 having a nail treatment space 14 configured to accommodate one or more fingers 11A, 11B, 11C, 11D, 11E (Figure 2) (or alternatively, toes) of a user 15, and to position and treat one or more nails 13A, 13B, 13C, 13D, 13E (Figure 2) of the user 15. As shown in Figures 1A and 1B, one end of the shell 12 is open, and its size and shape are adapted to accommodate the fingers 11A, 11B, 11C, 11D, 11E (Figure 2) (or alternatively, toes) of the user 15.

As shown in Figures 1A and 1B, the shell 12 may be formed of a rigid material (e.g., molded plastic) having a smooth outer surface 20 and an opening 22 leading to the nail treatment space 14 for inserting the user's fingers 11A, 11B, 11C, 11D, 11E (Figure 2) (or alternatively, toes). The shell 12 also includes an internal chamber 18 (Figure 1B) with light-reflective inner walls 25. In an exemplary embodiment, the shell 12 has a dome shape, defining the nail treatment space 14. Other representative shapes of the shell 12 besides the dome shape include spherical, box-shaped, elliptical, and combinations thereof. The shape of the shell 12 and the internal chamber 18 can be designed according to the needs of a specific application. The shell 12 also includes a flat bottom 30 configured to engage with a base 32. As shown in Figure 1B, the reflective inner wall 25 may include independent inserts made of highly reflective material to improve the efficiency of the curing process. The reflective inner wall 25 can be placed inside the outer casing 12, essentially as shown in Figure 1B, and can be secured by a retainer if necessary. Additionally, the LED light source 16 can be mounted on the reflective inner wall 25, essentially as shown in Figure 1B.

Referring again to Figures 1A, 1B, 2, and 2A, the nail product curing system 10 also includes one or more LED light sources 16 on the inner wall 25 for generating light in the nail processing space 14. The LED light source 16 may include one or more independent light-emitting diodes (LEDs) 26 (Figure 4), which are configured to directly illuminate the nails 13A, 13B, 13C, 13D, and 13E (Figure 2) of the user 15 placed within the nail processing space 14. The reflective inner wall 25 (Figure 1B) may include grooves 27 (Figure 1B) for the light-emitting diodes (LEDs) 26 to reduce the emission angle. Figure 1B illustrates an exemplary arrangement of LED light sources 16 on the inner wall 25 of the casing 12 for each fingernail 13A, 13B, 13C, 13D, 13E (Figure 2) of the user 15 (Figure 2). The LED light sources 16 are arranged in a separate array. In addition, the LED light sources 16 are in electrical communication with the circuit board 24 (Figure 1A) on the casing 12.

The wavelength of the light-emitting diodes (LEDs) 26 can be selected to suit a specific nail product 17, with peak wavelength intensity typically between 230 and 470 µm. Additionally, the LEDs 26 may include colored LEDs, such as green, yellow, red, or infrared for special skin treatments, UVC (230 nm to 280 nm) for disinfecting the nail treatment space 14, and the user's (Fig. 2) nails 13A, 13B, 13C, 13D, and 13E, as well as other components of the system. Furthermore, the peak wavelength intensity of the LEDs 26 can be adjusted or controlled via the circuit board 24 (Fig. 1A).

Circuit board 24 may contain one or more circuit boards, such as printed circuit boards (PCBs) or metal circuit boards, within housing 12, having various electronic components assembled in the circuit using designs and techniques known in the art. Additionally, as will be explained further, circuit board 24 may electrically communicate with other electrical components of nail product curing system 10 and provide power conversion for LED light source 16.

Referring to Figures 1A and 1B, the nail product curing system 10 also includes a light blocker 28 located on the housing 12, surrounding the opening 22 (Figure 1A) of the user 15, to prevent at least some light from escaping from the nail treatment space 14 and affecting the user's eyes. During operation of the nail product curing system 10, depending on the position of the user's eyes, at least some ultraviolet light may be seen by the user 15. The light blocker 28 is designed to prevent UV light from shining into the user's eyes during operation. The light blocker 28 may comprise one or more independent elements, which may be a reflective or absorbent material, having any desired size, shape, and position. Depending on the application, the light blocker 28 may be made of a transparent, solid, or translucent material. Any of these materials may be coated with a UV-reflective or UV-absorbing material. Representative materials for the light blocker 28 include plastics, metals, polymers, fibers, glass, and ceramics. An exemplary color for the light blocker 28 may be brown. As another example, the light blocker 28 may be attached to the housing 12 surrounding the opening 22 using a suitable fastener system or adhesive. Preferably, the light blocker 28 can be removed and reinstalled by a user. For some applications, the light blocker 28 may include an opening for airflow.

As shown in Figures 1A, 1B, and 3, the nail product curing system 10 may also include an external LED light 38 that is adjustable and removably mounted to the housing 12. The external LED light 38 is configured to allow inspection of the nail product 17 outside the nail treatment space 14 (Figure 2A). The external LED light 38 is in electrical communication with the circuit board 24 (Figure 1A) so that it can be powered without an additional power cord. The external LED light 38 may include one or more light-emitting diodes (LEDs) in the desired wavelength range, such as white light, colored light, UV light, blue light, or IR light. If the external LED light 38 contains UV or blue light, the nail product 17 can be cured externally without placing the user's nails 13A, 13B, 13C, 13D, 13E (FIG. 2) inside the nail treatment space 14. The external LED light 38 may also include one or more light-emitting diodes (LEDs) configured to emit UVC (230nm to 280nm) light for sterilizing the user's nails 13A, 13B, 13C, 13D, 13E (FIG. 2) and other components of the system 10. The external LED light 38 may optionally include a separate controller, power supply, indicator, display panel, battery pack, cooling fan, light receiver, and sensor.

As shown in Figures 1A and 1B, the nail product curing system 10 may also include a foldable handle 36 located on the housing 12 for transport. In addition to being foldable, the handle 36 may optionally include a controller, indicator, display panel, and sensor.

As shown in Figure 4, the nail product curing system 10 may also include a rechargeable battery 40 configured to power the electronic components with DC power. The housing 12 includes a battery socket 42, a battery cover 44, and an electrical connector 46 that communicates electrically with the charging circuitry of the battery 40. The electrical connector 46 can also be used to provide AC or DC power. The battery 40 makes the nail product curing system 10 portable and removable, similar to a battery on a power tool. Suitable battery types for the battery 400 include nickel-cadmium (Ni-Cd), lithium-ion (Li-ion), lithium polymer (Li-polymer), nickel-hydrogen (NiMH), lithium iron phosphate (LiFePO4), and supercapacitors.

As shown in Figures 5A and 5B, the nail product curing system 10 may also include a display panel 34 located on the housing 12 for displaying information. The display panel 34 is electrically communicated with the circuit board 24 and may include an LCD panel, an LED segment display panel, an OLED, or an e-ink display. The display panel 34 may be mounted outside the housing 12 or inside the housing 12 having a translucent window 48. The display panel 34 may provide information to the user 15, such as curing status, curing time, remaining curing time, light status, battery status, temperature, the brand name of the nail product 17, and other information depending on the nail product 17 and application requirements.

As shown in Figure 6, the nail product curing system 10 may also include a cooling system 50 located on the housing 12 (or alternately on the base 32), configured to cool the nail treatment space 14 and the user 15. The cooling system 50 may be located anywhere outside or inside the housing 12. The cooling system 50 includes a cooler 52 on the housing 12, a fresh air inlet 54 on the housing 12, and a hot air outlet 56 on the housing 12. The cooling system 50 is configured to cool the user 15's fingers 11A, 11B, 11C, 11D, 11E (or alternately toes) to make the curing process more comfortable. Cooler 52 may include a fan, turbine, evaporative cooler, piezoelectric cooler, or Peltier cooler. Fresh air inlet 54 and hot air outlet 56 may be located anywhere on housing 12 (or alternately on base 32) and may include multiple openings. In cooling system 50, heat transfer occurs from user 15’s fingers 11A, 11B, 11C, 11D, 11E (or alternately toes) and back of hand, as indicated by cooling airflow arrow 58. Cooling system 50 removes heat generated by the curing process and heat generated by user 15.

As shown in Figure 1A, the nail product curing system 10 also includes a sensing and control system 60, comprising a non-contact sensor 62 in the nail processing space 14, configured to sense and control various parameters of the curing process, such as the placement of the user's fingers 11A, 11B, 11C, 11D, 11E (Figure 2) (or alternatively, toes), curing time, curing sequence, and the function of the LED light source 16 on the inner wall 25 of the casing 12. As will be explained further, the non-contact sensor 62 uses inputs from the non-contact sensor 62 and programmed instructions contained on the circuit board 24 to control the LED light source 16 and the curing process. The sensing and control system 60 also includes a wireless transmission controller 64 on the housing 12, which is configured to assist the remote control and the non-contact sensor 62 in inputting information into the sensing and control system 60.

Non-contact sensors 62 (FIG. 1A) may be mounted on the housing 12 near the nail processing space 14 (FIG. 1A) and may contain multiple different sensors performing different functions. For example, one or more non-contact sensors 62 may be configured to sense the movement of the user 15's fingers 11A, 11B, 11C, 11D, 11E (FIG. 2) (or alternatively, toes) near or far, as well as their position and time when they are in a particular location. As will be explained further, the user 15's hand 86R (FIG. 7A) may be used to activate one or more non-contact sensors 62 to control various aspects of the curing process (e.g., "on", "off", "stop", "repeat"). For example, the non-contact sensor 62 (FIG. 1A) can be configured to sense changes in light or provide camera images of fingers 11A, 11B, 11C, 11D, 11E (FIG. 2) (or alternatively to toes) or the user 15's hand 86R. In alternative embodiments, the non-contact sensor 62 can also be configured to detect movements of the user 15's face, mouth, and hands. For example, the non-contact sensor 62 can include an optical sensor, a capacitive sensor, an IR sensor, a laser TOF sensor, an image sensor, or a voice sensor. Exemplary functions controlled by the non-contact sensor 62 include starting curing, stopping curing, changing the recipe, and changing the curing time. The settings and responses of the non-contact sensor 62 can be programmed using circuit board 24. The non-contact sensor 62 may also include feedback sensors, such as vibration and indicators (e.g., light), to indicate different layers of the curing process. The exact location of the non-contact sensor 62 on the housing 12 may vary depending on its function. For example, the non-contact sensor 62 may be mounted on the inner wall 25 (FIG. 1A) and outer surface 20 (FIG. 1A) of the housing 12 (FIG. 1A). One or more non-contact sensors 62 may also be mounted on the base 32 (FIG. 1A) and the handle 36 (FIG. 1A).

Referring to Figures 7A-7E, exemplary embodiments of the non-contact sensor 62 are shown. In Figure 7A, the right non-contact sensor 62R is located on the right side of the housing 12. The right non-contact sensor 62R can be configured to detect the movement or waving motion of the user 15's right hand 86R and control certain aspects of the curing process (e.g., curing formulation) based on that movement or waving motion of the right hand. For example, if the circuit board 24 is programmed with five separate formulations for the nail product 17, a separate waving motion of the right hand 86R on the right non-contact sensor 62R can select among the five formulations. In Figure 7B, the left non-contact sensor 62L is also on the outside of the housing 12, but on the left side. The left non-contact sensor 62L is configured to detect the movement or waving motion of the user 15's left hand 86L, and to control certain aspects of the curing process (e.g., curing formulation) based on this movement or waving motion of the left hand 86L. For example, waving the left hand 86L on the left non-contact sensor 62L can be used to switch between formulations (e.g., returning to formulation 2). Furthermore, the functions of the non-contact sensors 62R and 62L can be programmable and are not limited to a single function.

Referring to Figure 7C, a non-contact sensor 62D can be configured to detect when the user 15's hand 86L and fingers 11A, 11B, 11C, 11D, 11E (or alternatively, toes) enter the nail processing space 14. The non-contact sensor 62D can be mounted on the inner wall 25 of the housing 12 near the nail processing space 14. As shown in Figure 7C, the curing process can be stopped when the hand 86L is pulled out of the nail processing space 14.

Referring to Figure 7E, the non-contact hand entry and curing start sensor 62E can be configured to detect the entry of a hand, activate the LED light source 16 and start the countdown timer, and display the remaining time on the display panel 34. When the time is up, the LED light source 16 is turned off.

Referring to Figure 8, the wireless transmission controller 64 includes a remote control or remote controller having circuitry designed to receive and transmit signals 70 to and from a transceiver on the circuit board 24 (Figure 1A). In addition, the wireless transmission controller 64 may include a display 66 for displaying information about the curing process, and a keyboard 68 for inputting information to the circuit board 24 (Figure 1A). The information to be displayed may include the curing status of the nail product 17, curing time, remaining curing time, light status, battery status, temperature, and the brand name of the nail product 17. The wireless transmission controller 64 may also include a voice-activated communication system 88, which allows the user 15 to input messages to the circuit board 24 without touching any buttons. Exemplary technologies used in the wireless transmission controller 64 include Bluetooth, Long Term Evolution (LTE), Radio Frequency Identification (RFID), Universal Packet Radio Service (GPRS), Wi-Fi, Infrared Array (IrDA), Ultra Broadband (UWB), Zig-Bee, Near Field Communication (NFC), or via smartphones and applications (APP).

Referring to Figures 9, 10, 11A, and 11B, an exemplary embodiment of the base 32 is illustrated. As shown in Figure 9, the base 32 has a rounded edge 84 with a radius r > 5 mm, which prevents scratching of the user 15's hands and fingers 11A, 11B, 11C, 11D, 11E (Figure 2) (or alternatively, toes). This contrasts with conventional nail hardeners, which may contain sharp edges that could injure the user 15 through scratching. As shown in Figure 9, the base 32 provides a horizontal surface and forms the bottom side of the nail treatment space 14. Additionally, the base provides an ergonomic surface for the user 15's hands. In the exemplary embodiment shown in Figure 9, the base 32 is configured to slide into the housing 12. In Figure 10, the magnetic base 32M includes a magnet 72 that mates with a metal plate 74 on the housing 12. In Figures 11A and 11B, the pin/magnetic base 32PM includes an alignment hole 76 that mates with a positioning pin 78 on the housing 12, and a magnet 72 that engages with a metal plate 74 on the housing 12. The base 32 may include controller buttons, a display panel, a battery pack, a cooling fan, and one or more sensors.

Referring to Figure 12, an exemplary control circuit 80 for a nail product curing system 10 is illustrated. The control circuit 80 includes a circuit board 24 within a housing 12, containing electronic components that maintain electrical communication with a non-contact sensor 62 within the nail processing space 14. The circuit board 24 also includes electronic components that maintain electrical communication with a display panel 34 on the housing 12. The control circuit 80 further includes a wireless transmission controller 64 having a display 66 for displaying information about the curing process and a keyboard 68 for inputting information. The circuit board 24 includes electronic components that signal to the wireless transmission controller 64, and these electronic components can be powered by a battery 40. The wireless transmission controller 64 may also include a separate battery 82. Circuit board 24 also includes electronic components that electrically communicate with LED light source 16 and signal-communicate with wireless transmission controller 64. Circuit board 24 can be configured to control the operation of LED light source 16 using inputs from wireless transmission controller 64, including power, brightness, peak wavelength, on/off state, and operating time. If LED light source 16 comprises an array or group of individual light-emitting diodes (LEDs) 26, circuit board 24 can be configured to control the array or group separately according to inputs from wireless transmission controller 64. Circuit board 24 may include programmable electronic components, such as computer chips, which are pre-programmed (e.g., one-time programmable read-only memory ROM) or programmable (e.g., programmable read-only memory PROM) and use computer coding languages and PROM programmers. This program design also allows the curing process formula to be customized for specific nail products 17.

While several exemplary levels and embodiments have been discussed above, those skilled in the art will recognize certain modifications, permutations, additions, and subcombinations thereof. Therefore, it is intended that the appended and subsequently introduced claims be interpreted as including all such modifications, permutations, additions, and subcombinations contained within their true spirit and scope.
