[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In drier areas or in winter, the air humidity is low, and especially for people with dry skin, the face often feels tight. Using a facial steamer can hydrate the face, speed up blood circulation, and enhance skin elasticity and reduce spots and wrinkles.

[0031] However, the facial steamers currently on the market have only one function, which is facial steaming.

[0032] In order to solve the above technical problems, the present invention proposes a handheld phototherapy facial steamer, comprising a housing 10, a battery 20, a water tank assembly 30, an atomizing assembly 40 and a light emitting assembly 50. The atomizing assembly 40 can atomize the water inside the water tank assembly 30, and the light emitting assembly 50 can emit light of a predetermined wavelength to perform phototherapy on the facial skin. In this way, the handheld phototherapy facial steamer proposed by the present invention not only has the function of steaming the face, but also has the function of phototherapy.

[0033] The handheld light therapy facial steamer provided in an embodiment of the present invention is now described.

[0034] Please also read Figures 1 to 3 The handheld phototherapy facial steamer includes a shell 10, a battery 20, a water tank assembly 30, an atomization assembly 40 and a light-emitting assembly 50. The battery 20, the water tank assembly 30 and the atomization assembly 40 are arranged inside the shell 10. The battery 20 is electrically connected to the atomization assembly 40 and the light-emitting assembly 50. The atomization assembly 40 is used to atomize the liquid in the water tank assembly 30. The light-emitting assembly 50 is installed on the mist outlet side of the atomization assembly 40, and the light-emitting assembly 50 is used to emit phototherapy light.

[0035] The battery 20 is an electric energy storage component, which provides electric energy for components that need to be driven by electric energy, such as the atomizing component 40 and the light emitting component 50. The battery 20 is a disposable battery or a rechargeable and reusable battery.

[0036] The water tank assembly 30 has a water storage cavity for storing liquids such as clean water. The water tank assembly 30 has a water outlet 302, and the atomizing assembly 40 can atomize the liquid in the water tank assembly 30 at the water outlet 302 and spray it outward.

[0037] The atomizing assembly 40 can atomize liquid into droplets. For example, the water tank assembly 30 contains clean water, and the atomizing assembly 40 atomizes the water into water vapor. When the facial steamer is close to the face, the atomized water vapor is sprayed on the face to achieve the facial steaming function. After atomization, the atomizing assembly 40 generates steam at its atomizing port, and the side where the steam is sprayed is called the mist outlet side.

[0038] The light-emitting component 50 can emit light to perform phototherapy on the face. The light emitted by the light-emitting component 50 can be a single-band light or a combination of multiple bands. Light of different bands has different therapeutic effects on the skin. For example, the red light band can promote cell metabolism, increase the production of collagen, improve skin tone, and enhance skin elasticity; the blue light band can treat acne, reduce inflammation, and has a good therapeutic effect on acne; yellow light has a soothing and calming effect and can be used to repair sensitive skin. Among them, the side from which the light-emitting component 50 emits light is called the light-emitting side. It can be understood that the handheld phototherapy facial steamer has a use side that is in contact with the face or used at a distance from the face, and the light-emitting side of the light-emitting component 50 and the mist-emitting side of the atomizing component 40 are both arranged close to the use side.

[0039] The housing 10 is used to install the battery 20, the water tank assembly 30, the atomization assembly 40 and the light emitting assembly 50, and can protect the above structures and components.

[0040] The handheld phototherapy facial steamer in the above embodiment includes a housing 10, a battery 20, a water tank assembly 30, an atomization assembly 40 and a light-emitting assembly 50. The light-emitting assembly 50 can emit phototherapy light, and the atomization assembly 40 can atomize liquid, so that the facial steamer can not only atomize water vapor to hydrate the face, but also perform phototherapy on the face through the light-emitting assembly 50, thereby enriching the functions of the facial steamer.

[0041] In some embodiments of the present invention, see Figure 3 and Figure 5 The atomizing assembly 40 includes an atomizing element 41 installed at the water outlet 302 of the water tank assembly 30 and a heating element 61 for heating the water mist. The water mist atomized by the atomizing element 41 is heated by the heating element 61 and then output. The atomizing element 41 continuously converts the liquid water at the water outlet 302 into mist-like droplets. The heat generated by the heating element 61 heats the droplets and can further vaporize the droplets, thereby realizing the hot compress and hot steaming function for the face.

[0042] In some embodiments, the atomizer 41 is an ultrasonic atomizer, and the continuous vibration of the ultrasonic wave turns the liquid water into droplets.

[0043] In some embodiments, the heating element 61 may be a heating coil, which heats up and generates heat when powered on, thereby heating the atomized droplets.

[0044] In some embodiments of the present invention, see Figures 2 to 6The handheld light therapy facial steamer also includes a protective structure 62 for covering the heating element 61. The light-emitting component 50 is annular, and the outer edge of the light-emitting component 50 is fixed to the shell 10. The protective structure 62 is fixed to the inner edge of the light-emitting component 50, and the protective structure 62 is provided with a mist outlet 623; the light-emitting component 50 has a first axial extension portion 512 and a first radial extension portion 513, the first axial extension portion 512 is extended along the axial direction of the light-emitting component 50, and the first radial extension portion 513 is formed by radially inward extension of one axial end of the first axial extension portion 512; the protective structure 62 includes a protective end cover 621 and a second axial extension portion 622 formed by axial extension of the edge of the protective end cover 621; the protective end cover 621 is used to face the face, the protective end cover 621 is fixedly connected to the first radial extension portion 513, and the second axial extension portion 622 is arranged around the outer periphery of the first axial extension portion 512.

[0045] The ring-shaped shape of the light-emitting component 50 can be understood as the outer contour of the light-emitting component 50 is ring-shaped, and its various structural parts can be ring-shaped or not. The heating element 61 is a heat exchange component that can heat and generate heat. The protective structure 62 is used to shield the heating element 61. On the one hand, it can protect and seal the heating element 61, and on the other hand, it can prevent the user from being scalded by excessive temperature. The protective structure 62 is a heat-insulating structure made of a heat-insulating material. The axial direction in this embodiment is the axial direction of the mounting shell 51, and is perpendicular to the use side, and the radial direction is the radial direction of the mounting shell 51, and is parallel to the use side. Among them, the first axial extension portion 512 and the second axial extension portion 622 are both ring-shaped, and the first radial extension portion 513 and the guide end cover are both sheet-shaped. The protective structure 62 is fixed to the inner edge of the light-emitting component 50, which can be understood as the protective structure 62 is fixedly connected to the inner circumference of the light-emitting component 50 or the area close to the inner circumference. The protective structure 62 is provided with a mist outlet 623 , so that the mist vapor and liquid droplets generated by the atomizing sheet can be output to the face through the mist outlet 623 .

[0046] By setting the heating element 61 and the protective structure 62, the temperature of the use side of the light therapy facial steamer can be controlled to prevent the temperature from being too high, thereby improving the user experience. In addition, the protective structure 62 is set at the inner edge of the light emitting component 50, and the light emitting component 50 is annular, which can make full use of the space layout of the protective structure 62 and the light emitting component 50 on the use side. Compared with the circular light emitting component with the same diameter, the light intensity of the annular light emitting component 50 is less reduced, but the space in the center is reserved for installing the protective structure 62, making the structural layout more compact and reasonable.

[0047] By setting the first axial extension portion 512 and the first radial extension portion 513 on the light-emitting component 50, and the protective structure 62 includes a protective end cover 621 and a second axial extension portion 622, the second axial extension portion 622 is set on the outer periphery of the first axial extension portion 512, and the protective end cover 621 is covered on the first radial extension portion 513, so that the protective structure 62 and the mounting shell 51 have sufficient mounting structure, thereby realizing the fixed connection between the protective structure 62 and the mounting shell 51.

[0048] In some embodiments, the light emitting assembly 50 is annular. When the light emitting assembly 50 is annular, the outer surface of the beauty head housing 12 described below can be an arc surface accordingly, which is smaller and more beautiful. In other embodiments, the light emitting assembly 50 can also be square ring-shaped, that is, the light emitting assembly 50 is a frame-shaped structure.

[0049] In some embodiments, a mist outlet 623 is provided at the center of the protective structure 62. Alternatively, a plurality of mist outlets 623 are provided on the protective structure 62 and arranged in an array.

[0050] In some embodiments, the protection structure 62 is made of materials such as plastic, ceramic, glass, etc., and has a better heat insulation effect, which can protect the user from being burned.

[0051] In some embodiments, the second axial extension portion 622 is fixed to the outer periphery of the first axial extension portion 512 , and the second axial extension portion 622 and the first axial extension portion 512 may be fixedly connected by bonding, threading, or the like.

[0052] In some embodiments, the protective end cover 621 is fixedly mounted on the side of the first radial extension portion 513 facing the use side, and the first radial extension portion 513 and the protective end cover 621 can be fixedly connected by bonding, threading, etc.

[0053] In some embodiments, the side of the protective end cap 621 facing the face may be concave, so that the protective end cap 621 can adapt to the curve of the face and fit the face more closely.

[0054] In some embodiments, the handheld light therapy facial steamer further includes a front cover 81, which can be covered on the protective end cover 621 to cover the protective end cover 621 and the mist outlet 623, so that the protective end cover 621 can be kept clean and foreign matter can be prevented from entering the atomization area. The skirt portion of the front cover 81 is interference-fitted with the second axial extension portion 622, so that the front cover 81 can be detachably connected to the protective structure 62.

[0055] In some embodiments of the present invention, see Figures 3 to 6A flange 83 is fixed on the mist outlet side of the water tank assembly 30, a metal ring 831 is fixed on the flange 83, the heating element 61 is a coil, and the heating element 61 is sleeved and fixed on the outer periphery of the metal ring 831; the protective end cover 621 extends axially toward the water tank assembly 30 at the mist outlet 623 to form a third axial extension portion 624, and the third axial extension portion 624 extends into the metal ring 831.

[0056] The mist outlet side is arranged close to the use side of the phototherapy facial steamer, therefore, the water tank assembly 30 is at least partially arranged close to the use side, and the water tank assembly 30 is at least partially located in the beauty head shell 12. The metal ring 831 is made of metal, and the heating element 61 is a coil. When the coil is energized with alternating current, the magnetic field generated by the energized coil changes alternately at a high frequency, and eddy current heat is generated inside the metal ring 831, thereby achieving the heating of the atomized droplets. The metal ring 831 on the flange 83 is hollow, so that the atomization area can be exposed, and the protective end cover 621 is provided with a mist outlet 623 connected to the atomization area. In this way, when the atomization assembly 40 is working, the generated droplets are heated while passing through the inside of the metal ring 831, and then pass through the mist outlet 623 to reach the user's face.

[0057] By setting a metal ring 831 on the flange 83 and setting a third axial extension portion 624 at the mist outlet 623 of the protective end cover 621, the metal ring 831 and the third axial extension portion 624 are overlapped with each other, thereby forming a closed structure for accommodating the metal ring 831 and a relatively closed droplet channel for droplets to pass through. The droplets generated by the atomization assembly 40 pass through the metal ring 831 and the third axial extension portion 624 to the user's face, and the droplets will not enter the interior of the facial steamer.

[0058] In some embodiments, the flange 83 is a full metal structure; alternatively, the flange 83 is a partial metal structure, wherein at least the metal ring 831 is made of metal.

[0059] In some embodiments, the heating element 61 is interference-fitted with the metal ring 831, which facilitates the disassembly and assembly of the heating element 61. Alternatively, the axial ends of the heating element 61 are respectively limited by the flange 83 and the protective end cover 621, and the heating element 61 is gap-fitted with the metal ring 831.

[0060] In some embodiments, the flange 83 is fixed to the water tank assembly 30 by a plurality of circumferentially arranged threaded connectors.

[0061] In some embodiments, see Figure 5 A sink groove 832 is provided on the side of the flange 83 facing the water tank assembly 30, and the atomizer assembly 40 is arranged in the sink groove 832. In this way, the axial ends of the atomizer assembly 40 are respectively limited by the water tank assembly 30 and the flange 83, so that the atomizer assembly 40 is clamped between the water tank assembly 30 and the flange 83.

[0062] In some embodiments of the present invention, see Figures 3 to 6 The light-emitting component 50 includes a mounting shell 51, a lamp board 52 and an annular light guide 53. The mounting shell 51 is connected to the outer shell 10. An annular groove is provided on the mounting shell 51. The lamp board 52 is installed in the annular groove. The lamp board 52 is electrically connected to the battery 20. The annular light guide 53 covers the sealing annular groove. The light emitted by the lamp board 52 is emitted through the annular light guide 53.

[0063] The light board 52 has a plurality of light emitting parts 521, the mounting shell 51 is fixed to the housing 10, and the annular light guide 53 is used to face the face. The light board 52 has a plurality of light emitting parts 521, which can emit light toward the annular light guide 53. The annular light guide 53 can refract the light to make the emitted light more uniform.

[0064] The mounting shell 51 includes an annular main shell 511, a second radial extension portion 514 formed by radially extending the inner peripheral wall of the annular main shell 511 inwardly, a first axial extension portion 512 connected to the inner peripheral wall of the second radial extension portion 514, and a first radial extension portion 513 connected to the first axial extension portion 512. The annular main shell 511 has an annular groove for accommodating the lamp board 52. The second radial extension portion 514, the first axial extension portion 512 and the first radial extension portion 513 are all located outside the annular groove. The protective end cover 621 is fixedly connected to the first radial extension portion 513, and the second axial extension portion 622 is arranged around the outer periphery of the first axial extension portion 512.

[0065] In some embodiments, the mounting shell 51 is annular and the light board 52 is annular, so that the overall structure of the light emitting assembly 50 is annular.

[0066] In some embodiments, the annular light guide 53 is plate-shaped, which is equivalent to covering the annular light guide 53 on the annular main shell 511, which facilitates the manufacture of the annular light guide 53. Through the arrangement of the second radial extension portion 514, the first axial extension portion 512 and the first radial extension portion 513, the protective structure 62 can be conveniently fixed on the mounting shell 51.

[0067] In some embodiments, the cross section of the annular main shell 511 is U-shaped to form the above-mentioned accommodation space, and the top of the U-shaped structure is the opening of the accommodation space. The lamp board 52 can be fixed to the bottom of the U-shaped structure.

[0068] In some embodiments, the annular light guide 53 is glued and fixed to the annular main shell 511 .

[0069] In some embodiments of the present invention, see Figure 5 and Figure 7The water tank assembly 30 includes a water tank shell 31, an isolation shell 313 installed in the water tank shell 31, a first water absorption body 33 and a second water absorption body 34. The water tank shell 31 has a water inlet 301 and a water outlet 302. The atomization assembly 40 is arranged at the water outlet 302. The isolation shell 313 and the inner wall of the water tank shell 31 form a water absorption cavity. The first water absorption body 33 is arranged in the water absorption cavity. The second water absorption body 34 is arranged inside the water outlet 302, and the first water absorption body 33 and the second water absorption body 34 are in contact with each other.

[0070] The isolation shell 313 and the water tank shell 31 enclose a water absorption cavity for accommodating the first water absorption body 33, and the liquid inside the water tank shell 31 can enter the water absorption cavity. The first water absorption body 33 absorbs the liquid, the second water absorption body 34 absorbs the liquid from the first water absorption body 33, and the atomization component 40 atomizes the liquid at the first water absorption body 33 into droplets.

[0071] The liquid inside the water tank shell 31 passes through the first water absorbing body 33 and the second water absorbing body 34 to the atomizing assembly 40, and the first water absorbing body 33 covers the second water absorbing body 34, so that the water outlet 302 of the water tank shell 31 is blocked by two layers of water absorbing bodies, reducing the possibility of droplet leakage.

[0072] In some embodiments, the first water absorbent body 33 and the second water absorbent body 34 may be made of materials with strong water absorption capacity such as sponge.

[0073] In some embodiments, see Figure 7 The water tank housing 31 includes a front housing 312 and a rear housing 311. The front housing 312 is arranged close to the use side of the facial steamer, and the rear housing 311 is arranged away from the use side. The isolation housing 313 is fixed to the front housing 312, and the water outlet 302 is arranged at the part of the front housing 312 blocked by the isolation housing 313. The water inlet 301 can be arranged on the rear housing 311, away from the use side, so as to facilitate the water addition to the water tank assembly 30.

[0074] In some embodiments of the present invention, see Figure 5 and Figure 7 The housing 10 is provided with a water level window 121, and a water level display portion 3111 is formed on the surface of the water tank housing 31. The water level display portion 3111 is embedded in the water level window 121, and the water level display portion 3111 is a transparent structure. The water level window 121 is an opening on the housing 10. Therefore, the setting of the water level window 121 exposes part of the water tank housing 31, and the water level display portion 3111 embedded in the water level window 121 is transparent, so that the user can intuitively observe the water level in the water tank assembly 30. Among them, the water level display portion 3111 can be transparent or plate transparent, as long as the water level can be clearly seen.

[0075] By setting the water level display part 3111 as a transparent structure, and the water level display part 3111 is exposed through the water level window 121, the user can observe the water level conveniently, and can replenish water in time when the water level is low.

[0076] In some embodiments, part of the structure of the water tank shell 31 is transparent (including the water level display part 3111); or, the water tank shell 31 is entirely transparent.
