CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63144534 filed on February 2, 2021, which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] This section is intended to introduce the reader to aspects of art that may be related to various aspects of the present disclosure described herein, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure described herein. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0003] Currently, there are many tools that consumers, cosmeticians, or es- theticians use during facial cleaning or other types of facial work. One of the most popular tools is a facial treatment device for hydration. A facial treatment device for hydration can deliver steam and other forms of liquid to a user’s face. [0004] However, most of the conventional facial hydration devices are designed to merely accomplish a single function, such as applying warm water steam to the user’s face. Moreover, given the popularity of various tablet and computing devices, many users use such computing devices to schedule their beauty, health, and wellness routines, learn about trending beauty and wellness related methods, and the like. In addition, such devices are used for other unrelated functions as well that are not dedicated to providing interactivity or feedback to a user with respect to beauty or facial treatment devices. There currently does not exist any product on the market that integrates both a facial hydration device and the interactivity of a computing tablet device into one unitary appliance or device that can soften the skin, open pores, improve skin respiration, tone, and texture, among other benefits. Further, there are various health and wellness tracking and managing devices and software on the market, such as monitoring diet, sleep, and medical conditions, among others. However, no device exists that can combine health and wellness related features in combination with a facial treatment device.

[0005] Hence, what is needed is a single unitary combined facial hydrator and integrated tablet device that can also including functionality for lifestyle, health, beauty, and wellness purposes, and provide a cost-effective, optimal, interactive, engaging, and efficient solution for a user.

BRIEF SUMMARY

[0006] In one aspect of the disclosure described herein, an integrated facial treatment device and interactivity of a computing tablet device is disclosed for a unitary appliance or device. In addition, the facial treatment device can deliver skincare ingredients, water, and/or liquid in the form of small, micro or nano sized particles in combination with airflow/oxygen, sound waves and/or vibrations to get beyond the skin’s barrier instead of sitting on top of the skin. In addition, the facial treatment device can also operate as a steamer, humidifier, vaporizer, hydrator, mist, oxygenator, atomizer, cryotherapy and aromatherapy device which can disperse aroma or scents throughout a room. The integrated facial treatment device can soften the skin, open pores, improve skin respiration, tone, and texture, among other benefits. In particular, a water compartment feature of the device can provide steam, and a skincare compartment feature can provide skincare related fluids via skincare capsules inserted therein, among other features.

[0029] FIGS. 2A-7C illustrate one non-limiting exemplary embodiment of the IBFT 100 of the disclosure described herein. In particular, referring to FIG. 3, IBFT 100 can include the following: a digital computing device, tablet, and display 127; a lighted strip, lighted LED panel, light diffuser, or light pipe 101; a front panel screen mount 102 for receiving the lighted panel 101; a printed circuit board or controller 116; a digital video camera 120 in communication with controller 116; LED lighting units 119 emitting light through panel 101; a chambered base plate 108; a heater pad or heating or cooling element 124; an ultraviolet or UVC sanitation LED unit 118 in communication with controller 116; a CMS micro speaker or audio output device 123; a piezo disk or piezo atomizer 122; a centrifugal fan 125; a sliding cover capsule holder 105; a switching slider 106, a lower water stopper 107; an atomization chamber 109; a top piezo holder 115; a fluid heat or cooling (chilling or “cryo”) chamber 111; a lower water tube 110; a battery power source 121; a rear housing or casing 103; an outer stopper cap 112; a stopper cap plunger 114; a stopper cap bung 113; and a water tank compartment or casing 104. Here, LED lighting units 119 can be used for a variety of purposes and their intensities adjusted, such as for lighting a subject to take high resolution images or video, or for assisting with skin, blood, saliva, stool, or urine analysis captured by the camera. In particular, camera 120 can have various medical diagnostic related features. These diagnostic features can allow camera 120 to detect abnormalities on the skin of a user or within blood, saliva, stool, or urine samples analyzed by the camera (and controller 116) and provide feedback to the user. In addition, device 100 may also include an electrochemical biosensor for analyzing blood, saliva, stool, or urine samples. In addition, the controller 116 of device 100 may also communicate such diagnostic user data to a third party, such as the user’s physician for further feedback and analysis. In addition, device 100 may be able to compare images to a repository of images to provide feedback to the user.

[0030] Referring to FIGS. 4B and 5B, in one method of operation, the user can initiate a facial treatment procedure via the interactive display tablet or computing device 127 which sends commands to and from controller 16. In particular, as shown in FIG. 4B, controller 116 can then transmit a signal to one or more electro-motors or solenoid valves within device 100, wherein stopper assembly 112-114 is lifted to allow water or fluids from within tank 104 to be directed downwards, wherein stopper carrier 113A is further lifted, and water is directed to the heating or cooling (chilling or “cryo”) chamber 111, as shown in FIG. 4B. Here, the device 100 can automatically determine the amount of water or fluid to disperse from the tank, or in the alternative, the user can configure or define the water or fluid amount. Once the appropriate amount of water is dispensed, the stopper assembly 112- 114 can move to its closed position, as shown in FIG. 5B. Once the water or fluid reaches the heating or cooling chamber 111, it is heated or cooled (or chilled) to a pre-defined temperature via heating or cooling element 124. Afterwards, the heated or cooled (or chilled) water is atomized via piezo elements or atomizers 109A and 109B within the piezo holder unit 115. Next the atomized fluid or mist is then directed via a centrifugal fan 125 to atomized fluid chamber 109, which further directs it to area 109C, from which it is then dispensed out of nozzles 131. Here, independent of the heated water operation, one or more fluid based contents within a capsule 117 disposed within capsule holder 105 (wherein a pipe or tube 133 pierces a foil of capsule 117 to release and dispense its contents, as shown in FIG. 5B) can also be dispensed via atomizers 109A and 109B. Once the capsule fluid content is atomized via atomizers 109A and 109B, the atomized capsule fluid can be directed via the centrifugal fan 125 to the atomized fluid chamber 109, which further directs it to area 109C, from which it is then dispensed out of nozzles 131. [0031] Referring to FIGS. 6A-7C, device 100 allows the user to replace capsules 117 with device 100, wherein capsules 117 can be single-use capsules that can be disposed of after their contents are depleted. In another embodiment, capsules 117 may be re-fillable and re-usable. In particular, device 100 includes a hinged or capsule holder 105 that can be lifted into a raised position, such as shown in FIG. 6B, in order to release the capsule 117 within holder 105. Next, once holder 105 is in its raised position, then it can be pivoted or rotated outward, thereby exposing the capsule 117 within holder 105. Here, the user can then remove and replace the capsule 117, and insert a new or different capsule in an inverted configuration (e.g., its foil top facing down). Once the new capsule is inserted within holder 105, the user may pivot and close the rotatable holder 105. Next, the user can then secure and engage the capsule by sliding and pressing the holder 105 in a downward direction thereby securing it in place, as shown in FIG. 6B, such that the foil of capsule 117 is pierced via tube 133 to release and dispense its fluid contents. Once capsule 117 is engaged via tube 133, its contents can be dispensed within atomized chamber 109. Here, capsule 117 may be any type of cartridge, such as various aromas, scents, moisturizers, or fluids. In addition, capsules 117 may also include dietary or topical supplements, over the counter drugs, or pharmaceutical drugs, or any other type of medication that can be used for inhalation or topical application purposes. For example, an application on tablet 127 of device 100 may provide the user the ability to manage and schedule drug administration via device 100, including but not limited to dosage amounts, reminders, etc. In addition, device 100 may also communicate with any type of health care provider over a network to provide real time information such as drug dosage and administration history, and other related patient information. For example, tablet 127 may operate as a portal that allows the user to communicate with his/her healthcare provider such as video/audio while also having drugs administered. Further, capsules 117 can be configured such that they provide a certain amount of dosage of a drug, such as a 30-90 day supply. Alternatively, each capsule may be one dose of a drug.

[0032] Referring to FIGS. 2A-5B, IBFT or device 100 may include a casing or housing 104 that functions as a fluid or water basin or reservoir for storing fluid or water therein for distributing within the housing to be heated, atomized and dispense from device 100.
