Description

Technical Field

[0001] The utility model relates to the technical field of sonic skin care equipment, in particular to a mask-type air-coupled ultrasonic penetration-enhancing equipment. Background Art

[0002] In the modern skin care market, consumers have extremely diverse demands for skin care products, which is not only reflected in the pursuit of skin care product efficacy, but also in the demand for skin care products in different forms. Users will choose skin care products in different forms such as liquid, lotion, gel, essence, mask, cream, etc. for daily care according to their skin quality, seasonal changes, specific skin problems and personal preferences. In order to speed up the absorption of skin care products, a skin care product penetration-enhancing device that is easy to use and carry, can introduce skin care products in various forms, and acts on the entire face is needed.

[0003] The existing skin care product penetration-promoting device is mainly a handheld structure, which uses an ultrasonic transducer to promote penetration. The single-point ultrasonic transducer is directly attached to the local part of the skin or indirectly attached to the skin through other structures. When in use, the skin care product is applied locally to the use part, and then the front end of the handheld instrument is attached to the skin and used in circles. In the traditional handheld ultrasonic transducer penetration-promoting device, the ultrasound generated by the transducer can hardly vibrate the air, and the isolation of the air makes it impossible to transfer energy to the skin. The path of transducer-air-skin care products and skin cannot be realized. In order for the energy of the transducer to be transmitted into the skin, the acoustic impedance between the transducer-skin care products and the skin medium layer should be close, and air cannot be contained. Otherwise, the ultrasound generated by the transducer can hardly vibrate the air, and the isolation of the air makes it impossible to transfer energy to the skin, resulting in skin care products can only be used in the form of masks / essences / lotions, etc., and small areas. Therefore, when using the existing handheld ultrasonic transducer penetration-promoting device, it is necessary to attach it to the skin for contact circles, which is easy to be insufficiently absorbed for the essence substances in the skin care products. In order to achieve full absorption of the essence substances, it is necessary to apply repeatedly, which takes a long time. Utility Model Content

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0037] Combine the following Figure 1 to Figure 4 The specific structure and principle of the mask-type air-coupled ultrasonic permeation device of the utility model are described.

[0038] One embodiment of the utility model provides a mask-type air-coupled ultrasonic permeation device, see Figure 1 As shown, it includes a mask body 1 and a wearing structure 2 connected to the mask body 1, a visible window 3 is provided on the mask body 1 at a position corresponding to the eye socket, and a plurality of air-coupled transducers 4 are provided on the surface of the mask body 1 facing the wearing structure 2; a support body facing the wearing structure 2 is provided at the edge of the visible window 3, so that after the mask body 1 is worn through the wearing structure 2, an air gap is formed between the air-coupled transducer 4 and the user's face.

[0039] In the structure of the mask-type air-coupled ultrasonic permeation device of the present embodiment, a support body arranged at the edge of the visible window 3 allows an air gap to be formed between the air-coupled transducer 4 and the user's face during the wearing process of the user, that is, during the use of the device, the air-coupled transducer 4 does not directly contact the user's face or skin care products. The user applies the skin care products on the face and wears the device of the present embodiment through the wearing structure 2. The ultrasonic waves generated by the air-coupled transducer 4 act on the air gap formed between the air-coupled transducer 4 and the user's face.

[0040] It should be understood that the sound waves emitted by the air-coupled transducer 4 can be efficiently propagated in the air (i.e., can be propagated in the above-mentioned air gap) and act on the skin. When the ultrasonic wave is irradiated from the air to the skin surface, the following situations will occur: 1) Reflection: A part of the ultrasonic wave will be reflected back by the skin surface, and the degree of reflection depends on the difference in acoustic impedance between the two media (air and skin). Part of the energy will be reflected back, and the other part will enter the inside of the skin. 2) Absorption: Part of the energy of the ultrasonic wave will be absorbed by the skin. This will cause the local tissue to produce tiny vibrations, which will help promote the absorption of drugs or skin care products. 3) Conduction: The remaining energy will be conducted to deeper tissues through the skin. This helps to promote blood circulation in the deep layer of the skin, increase cell activity, and improve the skin's absorption capacity. Based on the effect of the above-mentioned air-coupled transducer 4, the ultrasonic wave generated by the air-coupled transducer 4 in this embodiment first acts on the air gap and then acts on the human body, which has the following obvious advantages: 1) Aerial effect, realizing that the air-coupled transducer 4 can transmit energy into the skin without directly contacting the skin. 2) It can adapt to various forms of skin care products, because the energy is transmitted to human skin through the air, and no matter what form of skin care products are, they will not affect the vibration of the skin and skin care products. 3) It can work on a larger area. The propagation of ultrasound through the air is similar to the propagation of light in the air. The air-coupled transducer 4 does not need to directly contact the skin, and the emitted ultrasound can be spread over a large range and act on a larger area.

[0041] It is understandable that the mask-type air-coupled ultrasonic penetration device of the present embodiment can be fixed to the user's skin care product introduction site through a mask-type structure or an arch-bridge structure, reducing the contact of the skin care products with the outside air during the introduction state, and reducing evaporation; it is easy to operate, safer, and avoids the risk of damaging the skin and leakage. At the same time, the device does not need to fit the skin tightly to achieve transdermal penetration of drugs or skin care products, improving safety and penetration effect. Products can be designed according to different introduction site shapes to expand the scope of application, with a wide range of applicability, and can be adapted to different types of skin care products to improve the penetration effect. Using the mask-type air-coupled ultrasonic penetration device of the present embodiment, the target area can be ultrasonically treated before applying drugs or skin care products, reducing the complexity and cost of the operation and saving time.

[0042] Specifically, in some specific examples of a mask-type air-coupled ultrasonic permeation device provided by the present invention, continue to refer to Figure 1 As shown, the mask body 1 includes an inner shell 11, a flexible circuit board 12 and a face shell 13, wherein a plurality of transducer channels 111 are provided on the inner shell 11, a first window 31 of a visible window 3 is formed on the inner shell 11, both sides of the inner shell 11 are connected to the wearing structure 2, and a support body is arranged at the edge of the first window 31; the flexible circuit board 12 is attached to the shell surface of the inner shell 11 away from the wearing structure 2, a second window 32 of the visible window 3 is formed on the flexible circuit board 12, a plurality of transducer mounting seats 121 are arranged on the flexible circuit board 12 for mounting the air-coupled transducer 4, the second window 32 and the transducer mounting seat 121 on the flexible circuit board 12 are arranged corresponding to the first window 31 and the transducer channel 111 on the inner shell 11 respectively; the face shell 13 is attached to the board surface of the flexible circuit board 12 away from the inner shell 11, of course, the face shell 13 and the flexible circuit board 12 may not be attached but leave a certain gap.

[0043] The inner shell 11 is used to form an air gap between the support body set at the edge of the first window 31 and the user's face. The flexible circuit board 12 provides the air coupling transducer 4 and the circuit electrical connection. The air coupling transducer 4 is fixed to the transducer mounting seat 121 and penetrates the transducer channel 111 on the inner shell 11. The ultrasonic wave emitted by the air coupling transducer 4 acts on the air gap formed between the inner shell 11 and the user's face. The face shell 13 is used for the overall appearance to be beautiful and practical. The first window 31 and the second window 32 constituting the visual window 3 facilitate unobstructed vision during use.

[0044] In some embodiments of a mask-type air-coupled ultrasonic permeation device of the utility model, a plurality of light-emitting diodes 122 are arranged on the board surface of the flexible circuit board 12 facing the inner shell 11. The position of the inner shell 11 corresponding to the light-emitting diodes 122 is set as a transparent part so that the light emitted by the light-emitting diodes 122 can pass through the inner shell 11; the position of the surface shell 13 corresponding to the second window 32 is set as a transparent part, and the remaining positions are sprayed with shielding paint.

[0045] See also Figure 2 As shown, several air-coupled transducers 4 and a plurality of light-emitting diodes 122 (LED lights) are connected to the flexible circuit board 12 by welding or other means. By arranging the light-emitting diodes 122 for light wave irradiation and heat generation, the absorption effect of the skin care products can be further improved. The position of the inner shell 11 corresponding to the light-emitting diodes 122 is set as a transparent part, which can be a transparent body or directly set in the form of a channel, so that the LED light can be irradiated to the face through the inner shell 11, and at the same time, the LED light is prevented from being directly exposed to the outside through the face shell 13. The face shell 13 and the inner shell 11 are appearance parts. The mask body 1 has a visible window 3 for the eyes, which is convenient for unobstructed vision during use. In order to ensure the beauty of the appearance, the preferred setting method of the visible window 3 is to use a transparent face shell 13. The face shell 13 corresponding to the position of the second window 32 is assisted by transparent paint or other methods, and the rest is blocked by spraying or other methods to achieve a higher level of visual and appearance effects.

[0046] In some other embodiments of the mask-type air-coupled ultrasonic permeation device of the utility model, the flexible circuit board 12 is connected to the controller 5, which can be specifically exposed by exposing some connection interfaces of the flexible circuit board 12 outside the mask body 1 and connected to the controller 5 through a connecting line; the controller 5 is provided with buttons and a software design interface for interactive control. The controller 5 is connected to the flexible circuit board 12 through a pluggable connecting line, and the controller 5 can be used to control the working intensity of the air-coupled transducer 4 and the number, intensity and wavelength of light irradiation of the light-emitting diode 122.

[0047] It is understandable that, combined with Figure 3As shown, the controller 5 in this embodiment contains buttons and UI interface for interaction, and optional sound configuration; the controller 5 also contains the treatment mode program for the device to work. The controller 5 can be held in one hand, is small in size and light in weight, and is connected to the flexible circuit board 12 of the mask body 1 through a pluggable line. Through the pluggable structural design, the controller 5 is also convenient for the treatment mode program to be updated remotely, that is, only the controller 5 is carried to complete the program burning. In a typical case, the treatment parameters of the mask-type air-coupled ultrasonic infiltration device can be defined by several wavelengths of the light-emitting diode 122 (LED light) + the working intensity of the air-coupled transducer 4, and its timing. For example, consider a red, yellow, and blue LED light + air-coupled transducer 4. In the case where the treatment parameters do not change with time, the output parameters of the treatment can be defined as: for ultrasonic introduction, the output energy is represented by an analog percentage, 0% is off, and 100% is the maximum power; for LED lights, red, yellow, and blue are represented by digital quantities 0 / 1 to represent the output energy, and the output parameters are represented by the combination of parameters plus the output time (unit: min, analog quantity, 0-20). For example, a basic output parameter can be described as: (Sonic=0.72, LED_R=1, LED_Y=1, LED_B=0, period=4) indicating 72% ultrasonic energy output, LED light status is red and yellow light on, blue light off, and treatment time is 4 minutes. Obviously, by controlling the brightness of several lights by 0-100%, and considering their adjustable changes over time, more complex treatment modes can be defined for use with different skin types / skin care products. For another example, the light emitting diode 122 (LED light) can also use four wavelengths of infrared (860nm) + red (630nm) + yellow (585nm) + blue (430nm). This example can achieve the adjustment of the number, brightness, intensity and timing of the four types, which is the same as the above-mentioned three-color light adjustment principle and will not be described in detail here.

[0048] In some specific examples, a fitting body is provided at the end of the support body at the edge of the visual window 3 facing the wearing structure 2, and the fitting body is made of food-grade soft silicone or foam material to fit the eye sockets and nose bridge of the user. Figure 1 As shown, the tightness of wearing can be adjusted through the wearing structure 2, and the mask body 1 as a whole maintains a large area of ​​coverage on the face, that is, the coverage area of ​​the face is greater than 80% (non-direct fit), reducing contact with the air. The fitting body is made of food-grade soft silicone or foam material, and fits with the soft eye socket and nose bridge, so that the force around the eye socket is evenly applied, and the wearing is comfortable without pressing the nose bridge.

[0049] Furthermore, the mask body 1 adopts a human facial ergonomic design structure, and the air gap size between the air-coupled transducer 4 and the user's face is no more than 3 cm. The ultrasonic energy emitted by the mask-type air-coupled ultrasonic permeation device of the present invention will propagate in the air gap. It should be understood that the attenuation of ultrasonic waves in the air is affected by frequency, ambient air pressure and temperature. Under typical normal temperature and pressure conditions, it is mainly determined by frequency, and its attenuation coefficient formula can be written as: α = a f 2 , which is proportional to the square of the frequency. Therefore, especially high-frequency ultrasound, the attenuation in the air is very obvious. For example, when referring to the standard temperature (25°C) and the standard atmospheric pressure (325kpa), the attenuation coefficient of 1MHz ultrasound in the air is 1.6dB / cm, that is, about 27% of the energy is lost every 1cm, and it is more serious at high frequencies. Therefore, it is necessary to keep the distance as small as possible while adapting to a variety of face shapes. In this embodiment, the air gap size between the air-coupled transducer 4 and the user's face is no more than 3cm, which ensures the existence of the air gap without causing large ultrasonic attenuation.

[0050] In some embodiments of a mask-type air-coupled ultrasonic permeation device of the utility model, the wearing structure 2 includes a back-head support body 21 and a strap 22 connecting the back-head support body 21 and the mask body 1, the strap 22 is an adjustable length strap, and a power drive device 6 is installed on the back-head support body 21; the back-head support body 21 and the power drive device 6 constitute the rear part of the mask, the mask body 1 and the air-coupled transducer 4 constitute the front part of the mask, and the weight of the back of the mask and the front of the mask are balanced.

[0051] See also Figure 3 As shown, the power drive device 6 provides power for the entire device, including hardware circuits such as hardware lithium batteries and drive circuits. The tightness of the wearing structure 2 is adjusted by the strap 22 to adapt to different face shapes. It is understandable that because the air-coupled transducer 4 often requires a higher driving voltage, the device size is bound to be larger and heavier, and the number of air-coupled transducers 4 in the mask form will also be larger, ranging from one to dozens, so the overall weight is greater than that of mask-type beauty devices based on other principles, such as LED beauty devices, so the characteristics of weight distribution are also based on this consideration. In this embodiment, the contents that must be placed in the front of the mask body 1 are placed in the front of the mask, and other heavier parts, including the wearing structure 2 and the power drive device 6, are placed in the back of the mask, and the front and back are determined according to the positional relationship with the human face when worn. Designed in this way, the size of the controller 5 will be as light and thin as possible, and the weight of the front and back parts of the mask will be nearly equal, forming a front-to-back balanced weight distribution design.

[0052] In some other specific embodiments of the present invention, the frequency of the air-coupled transducer 4 is 0.2-5 MHz. Figure 4As shown, the air-coupled transducer 4 includes a shell 41, a piezoelectric ceramic piece 42, a wire 43 and an impedance matching layer 44, wherein the shell 41 is cylindrical, mounted on the transducer mounting seat 121, and maintained perpendicular to the inner shell 11; the piezoelectric ceramic piece 42 is located in the shell 41; the wire 43 connects the piezoelectric ceramic piece 42 and the flexible circuit board 12; the impedance matching layer 44 is fitted and connected to the piezoelectric ceramic piece 42, and is located at the end of the shell 41 facing the wearing structure 2, and the impedance matching layer 44 protrudes 0.5 to 10 mm beyond the outermost end of the inner shell 11.

[0053] It can be understood that the impedance matching layer 44 is at the outermost part, and the air coupling transducer 4 is fixed vertically to the inner shell 11 as a whole, protruding 0.5 to 10 mm from the outermost end surface of the inner shell 11. When worn, the distance from the front end of the air coupling transducer 4 to the human face does not exceed 3 cm, and the distance is reduced as much as possible according to the selected frequency of the air coupling transducer 4. The inner shell 11 is provided with a specific profiling structure so that the sound waves emitted by the impedance matching layer 44 at the front end of the air coupling transducer 4 are perpendicular to the irradiated surface or at a smaller incident angle. It should be understood that according to the characteristics of the air coupling technology, the mechanism by which the sound waves finally act on the human face is that under a large difference in acoustic impedance, the sound waves will collide, conduct and reflect at the interface between the skin and the air, thereby applying the energy of the collision and conduction to the skin; the reflected sound waves will return again and repeat the process, thereby outputting a larger proportion of energy to the skin, thereby enhancing the purpose of opening the stratum corneum barrier. In order to increase the efficiency during the collision process, this embodiment is achieved by vertically ingesting the ultrasonic waves emitted by the air coupling transducer 4 into the skin or reducing the incident angle as much as possible. The front end of the air-coupled transducer 4 uses an impedance matching layer 44 to enable the emitted ultrasonic waves to directly pass through the air gap to irradiate the skin and the skin care products on the skin, etc., without passing through other media.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
