Description

Technical Field

[0001] The present invention relates to beauty therapy devices, and particularly to a photothermal steam beauty device.

Background Art

[0002] Current beauty devices include ultrasonic beauty devices and steam beauty devices, which directly act on the human body with ultrasonic waves or steam. Their action mechanisms are single and their functions are limited. Steam beauty devices mainly replenish moisture to the facial skin or the skin of other parts of the body with steam. The currently commercially available method is generally a high-temperature steam type, which generates steam by evaporating water under heating conditions. That is, water is heated to a high temperature and vaporized and then sprayed onto the face. However, in this method, it is difficult to adjust the temperature. When the temperature is low, the amount of steam decreases and it cannot meet the beauty needs. A certain preheating time is required for heating and vaporization, which affects the beauty effect. Since this method involves high-temperature heating, the physical sensation is not good. When approaching, a burning sensation is felt on the face, and there is a certain risk. The other is the low-temperature atomization type, that is, the cold spray technology. Since this method does not heat, the pores of the skin do not open, and after being sprayed on the face, the mist is not effectively absorbed.

[0003] Therefore, there is a need to provide a photothermal steam beauty device that can effectively generate mist, has an appropriate temperature, and has excellent beauty effects.

[0036] It should be understood that the terms used herein are merely for the purpose of describing the objectives of a particular embodiment and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “1,” “one,” and “the foregoing” used herein may also include the plural form. The terms “contains,” “includes,” “contains,” and “have” are inclusive and identify the presence of the described features, steps, operations, elements, and / or parts, but do not preclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof.

[0037] In this specification, multiple elements, members, regions, layers, and / or segments may be described using terms such as First, Second, Third, etc., but these elements, members, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, part, region, layer, or segment from another region, layer, or segment. Unless the context is clearly indicated, terms such as "First," "Second," and other numeral terms do not suggest an order or sequence when used in this specification. Accordingly, the First element, part, region, layer, or segment described below may be called the Second element, part, region, layer, or segment without departing from the teaching of the exemplary embodiments.

The fitting end opening is larger than or the same as the outer shape of the atomizing sheet 221, or the fitting end opening fits tightly to the outer shape of the atomizing sheet 221. Atomized molecules (e.g., mist) discharged from the spray end can enter the thermal cover 310 through the fitting end opening.

[0051] The heat-generating cover 310 further includes a heat-generating tank body 312. One side of the heat-generating tank body 312 is connected to the fitting sheet 311 and communicates with the other side. Atomized molecules that enter the fitting sheet 311 from the fitting end opening further enter the heat-generating tank body 312. The other side of the heat-generating tank body 312 is provided with an opening 3121 which also functions as the light irradiation end opening. The light source 320 is provided in the opening of the heat-generating tank body 312 and emits light rays from the opening 3121. Atomized molecules that enter the heat-generating tank body 312 are heated by the light source 320 as they pass through the light source 320 and sprayed from the opening 3121.

[0052] The area of ​​the cross-section of the light-heating tank body 312 gradually increases from the side closer to the fitting sheet 311 to the side closer to the opening 3121. This allows the atomizing molecules to gradually diffuse and come into sufficient contact with the light source. The shape of the cross-section of the light-heating tank body 312 is not limited, nor is the shape of the longitudinal section. In this embodiment, the cross-section of the light-heating tank body 312 is rectangular, but in other embodiments, it may be any shape such as square, round, elliptical, or irregular. In this embodiment, the longitudinal section of the light-heating tank body 312 is an inverted trapezoid, but in other embodiments, it may be any shape such as rectangular, square, triangular, circular, elliptical, or irregular. In this embodiment, the cross-section of the light-heating tank body 312 is rectangular, and the longitudinal section is an inverted trapezoid. This design effectively diffuses the atomizing molecules, making them easier to eject, allowing them to come into effective contact with the light source and effectively raise the temperature, while also being suitable for the shape of the light source and allowing the light source to be attached to the opening 3121.

[0053] As the light source 320, a halogen lamp, a carbon filament lamp, or a tungsten filament lamp can be used. The light source 320 can emit light in the near-infrared band and can be used to warm the skin and open pores, as well as to heat the atomized molecules in the photothermal tank body 312 to adjust the temperature of the discharged mist to suit the skin's moisture supply. To obtain light waves in a band suitable for physiotherapy, a light filter coating layer can be applied to the outer surface of the light source 320. Band ranges corresponding to different therapeutic effects are known in the art, and what is provided in this invention is a technical solution regarding how to obtain the required band. In addition to the green light coating layer, a filter film or filter sheet can also be installed on the light emission side.

[0054] The main body case 510 includes a main body 511 and a bottom plate 512. The main body 511 and the bottom plate 512 may be formed by combining and fixing two structures, or they may be an integrated structure. A spray nozzle 521 is provided in the main body case 510 or the upper case 520. The atomized molecules formed by atomizing the liquid in the liquid supply tank 110 by the atomizing functional member 210 are heated by the light source 320 and then discharged from the spray nozzle 521. Light rays from the light source 320 can also be emitted from the spray nozzle 521. In some embodiments, a panel 522 for the spray nozzle 521 is provided in the upper case 520. The panel 522 is made of a light-transmitting material, and light emitted from the light source 320 can also be emitted from the light-transmitting panel 522 on which the spray nozzle 521 is provided.

[0055] A short outlet pipe is provided at the first liquid inlet 113 of the liquid supply tank 110. The liquid supply tank 110 further includes a liquid shut-off assembly 130. The liquid shut-off assembly 130 includes a sealing knob 132, a liquid shut-off spring 133, a liquid shut-off device 134, and a liquid shut-off seal 131. The short outlet pipe is provided with a male thread. The sealing knob 132 is provided with a female thread that screws onto the male thread. The sealing knob 132 is provided with a through hole for connecting the inside and outside of the liquid supply tank 110. The liquid shut-off spring 133 is fitted onto the liquid shut-off device 134. The liquid shut-off device 134 is provided through the through hole in the sealing knob 132. The liquid shut-off seal 131 is provided inside the sealing knob 132 in the liquid shut-off device 134. If the liquid supply tank 110 is not attached to the main body case 510 of the facial device, the liquid shut-off spring 133 applies outward pressure to push the liquid shut-off device 134 outward, and the liquid shut-off device 134 pushes the liquid shut-off seal 131 outward, sealing the through-hole.

[0056] When liquid is injected into the liquid supply tank 110 and the liquid supply tank 110 is attached to the corresponding position on the main body case 510 of the facial device, the first liquid supply port 113 of the liquid supply tank 110 is connected to the first pipe port 1211 of the liquid supply pipe 120. An operating pin 1212 is provided at the first pipe port 1211. The operating pin 1212 applies pressure to the liquid circuit breaker 134. The liquid circuit breaker 134 opens when subjected to an inward pressing force, causing the liquid circuit breaker seal 131 to loosen, and the liquid flows out of the liquid supply tank 110 into the liquid supply pipe 120 and into the liquid outlet. The liquid outlet is provided with the first liquid absorption end 231 of the liquid absorption member 230. After the liquid reaches the first liquid absorption end 231, it is absorbed up to the second liquid absorption end 232. That is, it reaches a relatively high position from a relatively low liquid outlet. The liquid can reach and come into contact with the liquid supply end of the atomizing sheet at the second suction end 232 located at the second pipe opening 1231. The liquid is atomized by the atomizing sheet and ejected from the spray end.

[0057] The atomized mist enters the photothermal tank body 312 through the fitting end opening of the fitting sheet 311 and is sprayed onto the light source 320 of the photothermal unit. Since the light source 320 has a heat-generating effect, the mist can be heated. The mist heated by the photothermal unit exits through the opening 3121 and is ejected from the spray port 521 of the upper case 520.

[0058] The light-heat steam facial device of the present invention can effectively generate mist at an appropriate temperature and has a light irradiation beauty function. By using the light-heat steam facial device of the present invention, users can enjoy moisturizing with mist steam at an appropriate temperature and phototherapy with light in a specific wavelength range. In addition, the light irradiation helps to open pores by heating the skin, thereby enhancing the moisturizing effect. The near-infrared light source 320 can heat the skin and open pores. By heating the atomized mist with the photothermal action, the warm mist is retained and sprayed onto the skin, and in combination with near-infrared light, it can open pores and promote moisture absorption into the skin. Near-infrared light assists heating and at the same time acts on skin collagen, promoting collagen regeneration and resulting in a beautifying effect on the skin. The present invention's light-heat steam facial device simultaneously provides hydration with warm mist, light irradiation therapy, and skin whitening. It also heats the skin to enlarge pores, enhancing moisturizing and beautifying effects. It can perform multiple functions simultaneously, is comfortable to use without the risk of burns, has a simple overall structure, and is energy-efficient.
