Description

Technical Field

[0001] This application relates to a beauty therapy device, and more particularly to a photothermal facial steaming beauty device. Background Technology

[0002] Currently available beauty devices include ultrasonic beauty devices and steam beauty devices. These use ultrasound or steam to directly act on the human body, but their mechanisms of action are simple and their functions are limited. Steam beauty treatments primarily use steam to hydrate the skin on the face or other parts of the body. The methods currently on the market generally fall into two categories: high-temperature steam and low-temperature atomization. High-temperature steam is produced by evaporating water under heating conditions. Water is heated to a high temperature and then sprayed onto the face. However, the temperature is difficult to adjust, and the amount of steam decreases at low temperatures, failing to meet beauty needs. Heating and vaporization require a certain preheating time, affecting the beauty effect. Because this method involves high-temperature heating, the sensation is unpleasant, causing a burning sensation on the face and posing certain risks. The second type is low-temperature atomization, also known as cold spray technology. Because this method does not involve heating, the skin pores cannot open, and the water mist cannot be effectively absorbed after being sprayed onto the face.

[0003] Therefore, it is necessary to provide a photothermal facial steaming device that can effectively generate water mist at a suitable temperature and provide good beauty results. Summary of the Invention

[0004] The purpose of this application is to provide a photothermal facial steaming beauty device that can effectively generate water mist at a suitable temperature and has good beauty effects.

[0005] To achieve the purpose of this application, the following technical solution is provided:

[0006] This application provides a photothermal facial steaming beauty device, which includes a liquid supply unit, an atomizing unit, and a photothermal unit. The liquid supply unit has a liquid outlet end connected to the atomizing unit. The atomizing unit has a liquid supply end and a mist outlet end. The liquid from the liquid outlet end of the liquid supply unit contacts the liquid supply end of the atomizing unit.

[0013] In some embodiments, the liquid supply pipe is a U-shaped pipe, comprising a connected bottom horizontal pipe and first and second vertical pipes on both sides. The first vertical pipe, bottom horizontal pipe, and second vertical pipe are sequentially connected and internally communicate with each other. In some embodiments, the first vertical pipe, bottom horizontal pipe, and second vertical pipe are an integral structure. The first pipe opening is located at the open end of the first vertical pipe, and the second pipe opening is located at the open end of the second vertical pipe.

The liquid in the liquid supply tank enters the first pipe opening through the first liquid supply port, then flows through the first vertical pipe, the bottom horizontal pipe, and reaches the second vertical pipe.

[0014] In some embodiments, the liquid level in the second vertical pipe is related to the hydraulic pressure provided by the liquid level in the supply tank, which is a relatively simple structure. In other embodiments, the liquid level in the second vertical pipe is not limited, and when the liquid level in the supply tank is low, a small water pump can be used to raise the liquid level in the second vertical pipe.

[0019] In some implementations, a liquid supply tank may not be required, and the first port of the liquid supply pipe may be directly connected to a water source, such as a faucet or the outlet of a water purifier.

[0020] In some embodiments, the atomizing component is an ultrasonic atomizing plate. After the liquid comes into contact with the ultrasonic atomizing plate, it is converted into atomized molecules through ultrasonic transduction. For example, water is converted into fine water mist after ultrasonic atomization and sprayed out from the mist outlet.

[0021] In some embodiments, the atomizing unit further includes a liquid-absorbing element, one end of which is connected to the liquid supply end of the atomizing functional element, and the other end is inserted into the second port of the liquid supply pipe, entering the second vertical pipe and connecting to the liquid outlet end. The liquid-absorbing element can be made of absorbent cotton, such as absorbent cotton with a capillary structure or a fine denier fiber structure.

[0022] In some embodiments, the second vertical tube is shorter, and the second opening is positioned at a height close to or below the first liquid supply port of the liquid supply unit. The atomizing component of the atomizing unit is directly positioned at the second opening, and the liquid surface at the second opening can directly reach and contact the liquid supply end. In this case, the second opening is the liquid outlet. In other embodiments, the second vertical tube is longer, and the height of the second opening is higher than the height of the first liquid supply port. The liquid suction component of the atomizing unit extends into the second vertical tube, reaching a height close to or below the first liquid supply port of the liquid supply unit. The first suction end of the suction component at the lowest point of the second vertical tube contacts the liquid in the liquid supply tube, adsorbing the liquid and guiding it to the second suction end at the upper end of the suction component. The second suction end contacts and connects to the liquid supply end of the atomizing unit, providing liquid to the liquid supply end.

[0023] In some embodiments, the atomizing unit further includes an atomizing bracket, the atomizing functional component is disposed on the atomizing bracket, the atomizing bracket is provided with a through hole, one side of the through hole is connected to the liquid outlet end, and the other side of the through hole is connected to the liquid supply end of the atomizing functional component, and the liquid from the liquid outlet end reaches the liquid supply end of the atomizing functional component through the through hole.

[0024] In some embodiments, a sleeve is provided on one side of the atomizing bracket. The sleeve can be fitted onto the second port of the liquid supply pipe. The sleeve communicates with the second port and is also connected to a through hole on the atomizing bracket. The second liquid suction end of the liquid suction element can be inserted into the sleeve and the through hole and reach the liquid supply end of the atomizing functional element.

[0025] In some embodiments, an atomizing seat is provided on the other side of the atomizing bracket, and the atomizing functional component is disposed in the atomizing seat.

[0026] In some embodiments, the atomizing unit further includes a positioning member disposed on the atomizing functional component, which cooperates with the atomizing seat to fix the atomizing functional component. The positioning member has a mist outlet in the middle that communicates with the mist outlet end of the atomizing functional component. Further, the positioning member is a silicone ring with a sealing function.

[0027] In some specific embodiments, the atomizing functional component is an ultrasonic atomizing sheet, the atomizing seat is an annular structure with a notch adapted to the shape of the ultrasonic atomizing sheet, the annular structure forms a receiving groove, the ultrasonic atomizing sheet is installed in the receiving groove and connected to an atomizing sheet power cord, the atomizing sheet power cord extends out from the notch, and the positioning component is also provided with a tail end that can fix the power cord.

[0028] In some embodiments, the photothermal unit includes a photothermal cover and a light source. The photothermal cover has a socket end opening and a light-illuminating end opening. The socket end opening is connected to the mist-emitting end of the atomizing unit, and the light source is disposed at the light-illuminating end opening.

[0029] In some embodiments, the photothermal cover includes a socket with an opening at its lower end. The socket can be fitted onto the atomizing functional element of the atomizing unit, and the opening communicates with the mist outlet of the atomizing functional element. In some embodiments, the shape of the opening is adapted to the outer contour of the atomizing seat, the opening is larger than or equal to the outer contour of the atomizing seat, or the opening fits tightly with the shape of the atomizing seat. Atomized molecules (e.g., water mist) ejected from the mist outlet can directly enter the photothermal cover through the opening.

[0030] In some embodiments, the photothermal cover further includes a photothermal tank, one side of which is connected to and communicates with the socket. Atomized molecules that enter the socket through the socket end opening further enter the photothermal tank. The other side of the photothermal tank is provided with a slot. The light source is disposed in the photothermal tank and emits light from the slot. When the atomized molecules entering the photothermal tank pass through the light source, they are heated by the light source and then exit as mist from the slot.

[0031] In some embodiments, the light source can be a halogen lamp, carbon filament lamp, or tungsten filament lamp. The light source emits near-infrared light, which can be used to heat the skin and open pores, while simultaneously heating the atomized molecules within the photothermal tank, resulting in a sprayed water mist at a suitable temperature for skin hydration. The light source can be coated with a filter layer on its outer surface to obtain light waves suitable for therapeutic purposes. The wavelength ranges corresponding to different therapeutic effects are known in the industry. This application provides a technical solution for obtaining the desired wavelength range; in addition to a green light coating, a filter film or filter sheet can also be provided on the light-emitting side.

[0032] In some embodiments, the photothermal facial steamer further includes a main housing and an upper housing, which together form an internal accommodating space. The atomizing unit and the photothermal unit are disposed within this accommodating space. The liquid supply tube of the liquid supply unit is disposed within this accommodating space. The liquid supply tank of the liquid supply unit can be disposed inside the accommodating space, or the liquid supply tank can be disposed outside the main housing. The liquid supply port of the liquid supply tank is connected to the liquid supply tube inside the main housing. The main housing or the upper housing has a mist outlet. The liquid in the liquid supply tank is atomized by the atomizing component to form atomized molecules, which are then heated by the light source and discharged from the mist outlet. The light emitted by the light source can also be emitted from the mist outlet. In some embodiments, the panel of the upper housing with the mist outlet is made of a light-transmitting material, and the light emitted by the light source of the photothermal unit can also be emitted through the light-transmitting panel with the mist outlet.

[0033] In some embodiments, the liquid supply tank has a short outlet pipe at its first supply port. The liquid supply tank further includes a liquid blocking assembly, which includes a sealing knob, a liquid blocking spring, a liquid blocking device, and a liquid blocking seal. The short outlet pipe has an external thread, and the sealing knob has a mating internal thread. The sealing knob has a through hole connecting the inside and outside of the liquid supply tank. The liquid blocking spring is sleeved on the liquid blocking device, which passes through the through hole of the sealing knob. The liquid blocking seal is located on the inner side of the liquid blocking device within the sealing knob. In a first state, the liquid blocking spring applies pressure outward to push the liquid blocking device outward, and the liquid blocking device drives the liquid blocking seal outward to block the through hole. In a second state, an external force pushes the liquid blocking device inward, compressing the liquid blocking spring and simultaneously causing the liquid blocking seal to move inward, releasing the through hole, and allowing liquid to flow out from the through hole. A pin is provided at the first opening of the supply pipe. When the outlet short pipe is connected to the first opening of the supply pipe, the pin cooperates with the plugging device to provide a pushing force to the plugging device into the supply tank.

[0034] In a specific implementation, liquid is injected into the supply tank. When the supply tank is installed at the corresponding position on the main body of the beauty device, the first supply port of the supply tank connects to the first port of the supply pipe. The liquid blocker is opened by an inward pushing force, causing the liquid-blocking seal to loosen. The liquid flows out from the supply tank into the supply pipe and then to the outlet end. In some embodiments, the outlet end is provided with a first suction end of the suction element. After the liquid reaches the first suction end, it is sucked to the second suction end, that is, from the lower outlet end to the higher position. The liquid at the second suction end located at the second port can reach and contact the supply end of the atomizing functional plate. After being atomized by the atomizing functional plate, it is sprayed out from the mist outlet end.

[0035] After atomization, the water mist enters the photothermal tank through the socket end opening of the socket and is sprayed toward the light source of the photothermal unit. Since the light source has a heating effect, it heats the water mist. After being heated by the photothermal unit, the water mist exits through the slot and is then sprayed out through the mist outlet of the upper shell.

[0036] Compared with the prior art, this application has the following advantages:

[0037] This photothermal facial steamer effectively generates water mist at a suitable temperature and also features phototherapy. Using this device allows users to simultaneously enjoy hydrating water mist and specific wavelengths of light. The light stimulation also helps open pores and enhance hydration. Near-infrared light heats the skin, opening pores; the photothermal effect heats the atomized water mist, maintaining a warm spray on the skin, which, combined with the near-infrared light opening pores, promotes better moisture absorption. The near-infrared light also acts on collagen, promoting collagen regeneration and beautifying the skin. This photothermal facial steamer simultaneously provides warm water mist hydration, phototherapy, and skin whitening. Heating the skin expands pores and enhances hydration, offering multiple functions without the risk of burns. It is comfortable to use, has a simple structure, and high energy efficiency.

The photothermal facial steamer also includes a liquid supply unit, an atomizing unit, and a photothermal unit. The liquid supply unit is connected to the atomizing unit, and the photothermal unit is located on one side of the mist outlet of the atomizing unit. Liquid supplied by the liquid supply unit flows to the atomizing unit, is atomized, and then reaches the photothermal unit, where it is heated by photothermal heat and then emitted as mist. The atomizing unit and the photothermal unit are disposed within the accommodating space.

[0047] The liquid supply unit includes a liquid supply tank 110 and a liquid supply pipe 120. The liquid supply tank 110 includes a detachably mounted housing 111 and a cover 112, which cooperate to form an internal liquid cavity.

The liquid supply pipe 120 of the liquid supply unit is located in the accommodating space, and the liquid supply tank 110 of the liquid supply unit is located on the outside of the main housing 510. The liquid supply port of the liquid supply tank 110 communicates with the liquid supply pipe 120 inside the main housing 510.

[0048] The liquid supply pipe 120 is a U-shaped pipe, comprising a bottom horizontal pipe 122 and two first vertical pipes 121 and second vertical pipes 123 connected to each other. The first vertical pipe 121, the bottom horizontal pipe 122, and the second vertical pipe 123 are sequentially connected and internally communicate with each other. In some embodiments, the first vertical pipe 121, the bottom horizontal pipe 122, and the second vertical pipe 123 are an integral structure. The liquid supply pipe 120 is provided with a first pipe opening 1211 and a second pipe opening 1231. The first pipe opening 1211 is located at the open end of the first vertical pipe 121, and the second pipe opening 1231 is located at the open end of the second vertical pipe 123.

[0049] The first vertical pipe 121 and the second vertical pipe 123 of the U-shaped liquid supply pipe 120 can have the same or different lengths. In this embodiment, the second vertical pipe 123 is longer than the first vertical pipe 121. The liquid in the liquid supply tank 110 enters the first pipe opening 1211 through the first liquid supply port 113, and then flows through the first vertical pipe 121, the bottom horizontal pipe 122, and reaches the second vertical pipe 123. In some embodiments, the liquid level in the second vertical pipe 123 is related to the hydraulic pressure provided by the liquid level in the liquid supply tank 110. This structure is relatively simple.

The mist outlet end is arranged opposite to the liquid supply end. In a specific embodiment, the atomizing functional element 210 is an ultrasonic atomizing plate. After the liquid contacts the ultrasonic atomizing plate, it is transformed into atomized molecules through ultrasonic transduction. For example, water is transformed into a fine water mist after ultrasonic atomization and is ejected from the mist outlet end.

[0051] The atomizing unit also includes a liquid-absorbing component 230. One end of the liquid-absorbing component 230 is connected to the liquid supply end of the atomizing functional component 210, and the other end is inserted into the second port 1231 of the liquid supply pipe 120, entering the second vertical pipe 123.

The liquid-absorbing component 230 can be made of absorbent cotton, such as absorbent cotton with a capillary structure or fine denier fiber structure. The liquid outlet is located at the connection to the second port, which is connected to the liquid supply end of the atomizing unit. The first liquid supply port 113 is connected to and communicates with the first port 1211 of the liquid supply pipe 120. The first liquid supply port 113 and the first port 1211 of the liquid supply pipe 120 are detachably connected.

The sleeve 222 communicates with the second port 1231 and also communicates with the through hole 223 on the atomizing bracket 220. The second liquid suction end 232 of the liquid suction member 230 can be inserted into the sleeve 222 and the through hole 223 and reach the liquid supply end of the atomizing functional member 210.

[0054] On the other side of the atomizing bracket 220, there is an atomizing seat 221, and the atomizing functional component 210 is disposed in the atomizing seat 221. The atomizing unit also includes a positioning component 240, which is disposed on the atomizing functional component 210 and cooperates with the atomizing seat 221 to fix the atomizing functional component 210.

The positioning member 240 also has a tail 241 for fixing the power cable, and its size is adapted to the ultrasonic atomizing plate. In a specific embodiment, the positioning member 240 is mounted on the ultrasonic atomizing plate 210, which is mounted in the annular atomizing base 221 and positioned on the atomizing bracket 220. The circuit board 400 is specifically an atomization control circuit and a light source control circuit, or it may include a chip with control programs for various functional modes, such as controlling the size of the fog, the fog temperature, and the brightness of the light, such as controlling the atomization and illumination mode, single illumination mode, single atomization mode, etc.

[0056] The photothermal unit includes a photothermal cover 310 and a light source 320. The photothermal cover 310 has a socket end opening and a light-illuminating end opening.

[0057] The photothermal cover 310 includes a socket 311, with a socket end opening (not shown) located at the lower end of the socket 311. The socket 311 can be sleeved on top of the atomizing functional component 210 of the atomizing unit, and the socket end opening communicates with the mist outlet end of the atomizing functional component 210. The shape of the socket end opening is adapted to the outer contour of the atomizing seat 221, and the socket end opening is larger than or equal to the outer contour of the atomizing seat 221, or the socket end opening is tightly fitted to the shape of the atomizing seat 221. The atomized molecules (e.g., water mist) ejected from the mist outlet end can directly enter the photothermal cover 310 through the socket end opening.

[0058] The photothermal cover 310 also includes a photothermal tank 312. One side of the photothermal tank 312 is connected to and communicates with the socket 311. The atomized molecules that enter the socket 311 through the socket end opening further enter the photothermal tank 312. The other side of the photothermal tank 312 is provided with a slot 3121, which also serves as the light-illuminating end opening. The light source 320 is located at the slot of the photothermal tank 312 and emits light from the slot 3121. When the atomized molecules entering the photothermal tank 312 pass through the light source 320, they are heated by the light source 320 and then exit as mist from the slot 3121.

[0059] The cross-sectional area of ​​the photothermal tank 312 gradually increases from the side near the socket 311 to the side near the slot opening 3121, allowing the atomized molecules to gradually diffuse and fully contact the light source. The cross-sectional shape of the photothermal tank 312 is not limited, nor is the longitudinal cross-sectional shape. In this embodiment, the cross-section of the photothermal tank 312 is rectangular; in other embodiments, it can be any shape such as square, circular, elliptical, or irregular. In this embodiment, the longitudinal cross-sectional shape of the photothermal tank 312 is an inverted trapezoid; in other embodiments, it can be any shape such as rectangular, square, triangular, circular, elliptical, or irregular. In this embodiment, the cross-section of the photothermal tank 312 is rectangular, and the longitudinal cross-sectional shape is an inverted trapezoid.

[0060] The light source 320 can be a halogen lamp, a carbon filament lamp, or a tungsten filament lamp. The light source 320 emits near-infrared light, which can be used to heat the skin and open pores, while simultaneously heating the atomized molecules within the photothermal tank 312, resulting in a sprayed water mist at a suitable temperature for skin hydration. The light source 320 can be coated with a filter layer on its outer surface to obtain light waves suitable for therapeutic purposes. The wavelength ranges corresponding to different therapeutic effects are known in the industry. This application provides a technical solution for obtaining the desired wavelength range; in addition to a green light coating, a filter film or filter sheet can also be provided on the light-emitting side.

[0061] The main housing 510 includes a main body 511 and a base plate 512. The main body 511 and the base plate 512 can be two structures combined and fixed to form the main housing 510, or they can be an integral structure. The main housing 510 or the upper housing 520 is provided with a mist outlet 521. The liquid in the liquid supply tank 110 is atomized by the atomizing functional component 210, forming atomized molecules. These molecules are then heated by the light source 320 and discharged from the mist outlet 521. The light emitted from the light source 320 can also be emitted from the mist outlet 521. In some embodiments, the panel 522 of the upper housing 520 with the mist outlet 521 is made of a light-transmitting material, and the light emitted from the light source 320 of the photothermal unit can also be emitted through the light-transmitting panel 522 with the mist outlet 521.

[0062] The liquid supply tank 110 is provided with a short outlet pipe at the first liquid supply port 113. The liquid supply tank 110 further includes a liquid blocking assembly 130, which includes a sealing knob 132, a liquid blocking spring 133, a liquid blocking device 134, and a liquid blocking seal 131. The short outlet pipe has an external thread, and the sealing knob 132 has an internal thread that mates with it. The sealing knob 132 has a through hole that connects the inside and outside of the liquid supply tank 110. The liquid blocking spring 133 is sleeved on the liquid blocking device 134. The liquid blocking device 134 passes through the through hole of the sealing knob 132, and the liquid blocking seal 131 is located on the inner side of the liquid blocking device 134 within the sealing knob 132. When the liquid supply tank 110 is not assembled into the main housing 510 of the beauty device, the liquid blocking spring 133 applies pressure outward to push the liquid blocking device 134 outward, and the liquid blocking device 134 drives the liquid blocking seal 131 outward and blocks the perforation.

[0063] Liquid is injected into the liquid supply tank 110. When the liquid supply tank 110 is installed in the corresponding position on the main body housing 510 of the beauty device, the first liquid supply port 113 of the liquid supply tank 110 is connected to the first port 1211 of the liquid supply pipe 120. A pin 1212 is provided at the first port 1211. The pin 1212 applies pressure to the liquid blocker 134, and the liquid blocker 134 is pushed inward to open, causing the liquid-blocking seal 131 to loosen, and liquid flows out from the liquid supply tank. 110 flows out into the liquid supply pipe 120, and then flows to the liquid outlet end. The liquid outlet end is provided with the first liquid suction end 231 of the liquid suction member 230. After the liquid reaches the first liquid suction end 231, it is sucked to the second liquid suction end 232, that is, from the lower liquid outlet end to the higher position. The liquid at the second liquid suction end 232 located at the second pipe opening 1231 can reach and contact the liquid supply end of the atomizing functional plate. After being atomized by the atomizing functional plate, it is sprayed out from the mist outlet end.

[0064] After atomization, the water mist enters the photothermal tank 312 through the socket end opening of the socket 311 and is sprayed toward the light source 320 of the photothermal unit. Since the light source 320 has a heating effect, it heats the water mist. After being heated by the photothermal unit, the water mist exits through the slot 3121 and is then sprayed out through the mist outlet 521 of the upper shell 520.

[0065] This photothermal facial steamer effectively generates water mist at a suitable temperature and also features phototherapy. Using this device allows users to simultaneously enjoy hydrating water mist and phototherapy with specific wavelengths of light. The light stimulation also helps open pores and enhance hydration. It utilizes a 320nm near-infrared light source to heat the skin and open pores; the photothermal effect heats the atomized water mist, maintaining a warm spray on the skin, which, combined with the near-infrared light opening pores, promotes better moisture absorption. The near-infrared light also acts on skin collagen, promoting collagen regeneration and beautifying the skin. This photothermal facial steamer simultaneously provides warm water mist hydration, phototherapy, and skin whitening. Heating the skin expands pores and enhances hydration, offering multiple functions at once without the risk of burns. It is comfortable to use, has a simple structure, and high energy efficiency.
