Description

Technical Field

[0001] The present invention relates to a facial mask type beauty instrument and a use method thereof, and in particular to a facial mask type beauty instrument with a carbon nanotube layer as a functional layer and a use method thereof. Background Art

[0002] As people's material living standards continue to improve, people's demand for beauty is also getting higher and higher. As a result, beauty flexible masks and beauty instruments are selling well. In particular, beauty instruments are loved by more and more people because they can generate microcurrents on the face to stimulate the face and achieve the effect of beauty and skin care. Existing beauty instruments are all handheld beauty instruments. When using, people need to hold them in their hands and stand in front of a mirror. This makes handheld beauty instruments very inconvenient to use. Moreover, handheld beauty instruments need to be operated on one side of the face before operating on the other side. Manual operation can easily cause inconsistent facial action sites on both sides, or different strengths, and long-term use may cause facial asymmetry. Summary of the invention

[0003] In view of this, it is indeed necessary to provide a facial mask type beauty instrument and a method of using the same to overcome the above shortcomings.

[0004] A facial mask type beauty instrument, comprising a flexible facial mask and a controller, wherein the controller is used to control the flexible facial mask, and the flexible facial mask comprises:

[0005] a flexible layer;

[0006] a flexible porous layer, wherein the flexible layer and the flexible porous layer are stacked, and the flexible layer and the flexible porous layer are both provided with openings for eyes and a mouth corresponding to each other;

[0007] and a plurality of functional layers, wherein the plurality of functional layers are arranged between the flexible layer and the flexible porous layer; the plurality of functional layers are symmetrically distributed or regularly distributed, wherein each pair of functional layers or each functional layer in the plurality of functional layers is electrically connected to an electrode, and the multilayer functional layer is defined to include K (K=1, 2, 3, 4, 5...) pairs / individual functional layers, and the K pairs / individual functional layers are electrically connected to K (K=1, 2, 3, 4, 5...) electrodes;

[0008] The controller is electrically connected to the K electrodes, and controls multiple functional layers in the flexible mask through the K electrodes; wherein the functional layer is a carbon nanotube layer.

[0009] The flexible layer or the flexible porous layer is provided with a window, and the K wires are exposed from the window and electrically connected to the controller.

[0010] During application, the electrodes are energized in a cyclic manner with electrode numbers 1 and 2, 2 and 3, 3 and 4...k-1 and K, thereby applying a voltage between the two pairs of functional layers, generating microcurrents on the skin between the two pairs of functional layers, stimulating the skin sequentially or selectively.

[0011] The positions of two pairs of functional layers with adjacent numbers can be arranged adjacently or at intervals. The two pairs of functional layers with adjacent numbers, such as 2 and 3, do not mean that the positions of the two pairs of functional layers are adjacent. The positions of the two pairs of functional layers with adjacent numbers can be arbitrarily set according to actual needs.

[0012] Preferably, an insulating layer may be disposed on the surface of the electrode to prevent the electrode from being oxidized during use.

[0013] The material of the flexible layer can be: non-woven fabric, silk, ordinary flexible cloth, porous flexible paper, silica gel and other flexible materials, which can be directly attached to the face of a person.

[0014] The material of the flexible porous layer can be: non-woven fabric, silk, ordinary flexible cloth, porous flexible paper, silica gel and other flexible materials with porous structure, which can be directly attached to the face of a person and the beauty essence can penetrate.

[0016] The carbon nanotube layer may also be a carbon nanotube slurry layer.

[0017] The carbon nanotube layer may also include one carbon nanotube wire or multiple carbon nanotube wires. When the carbon nanotube layer includes one carbon nanotube wire, the one carbon nanotube wire may be spirally arranged to form a layered structure. When the carbon nanotube layer includes multiple carbon nanotube wires, the multiple carbon nanotube wires may be arranged in parallel or cross-arranged to form a layered structure.

[0018] Compared with the prior art, the facial mask-type beauty instrument and the method of use thereof provided by the present invention can be directly attached to a person's face without the need for hand support, thus freeing the user's hands; at the same time, by controlling the circuit through a controller, selective facial skin stimulation can be achieved, and the parts that need stimulation can be selected more accurately without causing facial asymmetry.

[0044] The facial mask type beauty instrument and the use method thereof provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The first embodiment of the present invention provides a facial mask type beauty instrument. The facial mask type beauty instrument includes a flexible facial mask and a controller, and the controller is used to control the flexible facial mask. Figure 1 and Figure 2 The flexible mask 100 includes: a flexible layer 102; a flexible porous layer 106, wherein the flexible layer 102 and the flexible porous layer 106 are stacked (for clarity, Figure 1 The flexible layer 102 and the flexible porous layer 106 are shown separately in the figure, and the flexible layer 102 and the flexible porous layer 106 are both provided with corresponding eye and mouth openings (not marked in the figure); and multiple functional layers 104, the multiple functional layers 104 are arranged between the flexible layer 102 and the flexible porous layer 106; the multiple functional layers 104 are symmetrically distributed or regularly distributed, wherein each pair or each functional layer 104 in the multiple functional layers 104 is electrically connected to an electrode 108. The number of electrodes 108 is defined as K (K = 1, 2, 3, 4, 5 ...), then the number of functional layers 104 is K (K = 1, 2, 3, 4, 5 ...) pairs or K. The controller is electrically connected to the K electrodes 108, and controls the multiple functional layers 104 in the flexible mask 100 through the K electrodes 108; wherein each functional layer 104 is a carbon nanotube layer. The number of the functional layers 104 is not limited and can be set at any position of the flexible mask 100 as needed. The area of ​​the functional layer 104 can be different and can be adjusted as needed. In this embodiment, the number of the functional layers 104 is 8 layers, which are symmetrically distributed on the two cheeks of the flexible mask 100, and the area of ​​the functional layer 104 gradually decreases from top to bottom.

[0046] The controller is provided with a plurality of function buttons for controlling the flexible mask 100. Each function button can control the current size, the frequency of the current, the position of the input current, etc., so as to control the functional layer 104 inside the flexible mask and realize different functions. The flexible mask 100 can be movably connected to the controller. In this embodiment, the flexible mask 100 has a reserved access port at the position of its window 110, and the controller is connected to the flexible mask 100 through the access port. The flexible mask 100 can be replaced as needed. The flexible mask 100 can also be cleaned to achieve the purpose of reuse.

[0047] Optionally, the flexible layer 102 or the flexible porous layer 106 is provided with a window, and the K wires are exposed from the window and electrically connected to the controller. Figure 1 As shown, the flexible layer 102 is provided with a window 110 , and the K electrodes 108 are exposed from the window 110 and are electrically connected to the controller.

[0048] The material of the flexible layer 102 can be: non-woven fabric, silk layer, ordinary flexible cloth, porous flexible paper, silica gel and other flexible materials, which can be directly attached to the face of a person. The thickness of the flexible layer 102 can be set according to actual needs. In this embodiment, the thickness of the flexible layer 102 is 10 microns to 100 microns. The flexible layer 102 can be a porous structure or a non-porous structure. The material of the flexible porous layer 106 can be: non-woven fabric, silk layer, ordinary flexible cloth, porous flexible paper, silica gel and other flexible materials with porous structures, which can be directly attached to the face of a person. The material of the flexible porous layer 106 can be the same as the material of the flexible layer 102 or different. The flexible porous layer 106 is a porous material, which is provided with a plurality of micropores. When in use, the flexible porous layer 106 is directly attached to the face of a person, and the beauty liquid can seep out from the plurality of micropores and act on the face of a person. The thickness of the flexible porous layer 106 can be set according to actual needs. In this embodiment, the thickness of the flexible porous layer 106 is 10 micrometers to 100 micrometers.

[0049] The shape of the K electrodes 108 is not limited, and can be a conductive film, a metal sheet or a metal lead. Preferably, the K electrodes 108 are all a linear conductive film, and the thickness of the linear conductive film is not limited. The material of the electrode 108 can be metal, alloy, indium tin oxide (ITO), antimony tin oxide (ATO), conductive silver glue, conductive polymer or conductive carbon nanotube, etc. The metal or alloy material can be aluminum, copper, tungsten, molybdenum, gold, titanium, neodymium, palladium, cesium or an alloy of any combination thereof. In this embodiment, the k electrodes 108 are all linear copper conductive films with a thickness of 1 micron. The electrode 108 should be made of a material with good flexibility and a small thickness. Preferably, the width or diameter of the electrode 108 is less than or equal to 500 microns, and the thickness is less than or equal to 200 microns. Preferably, an insulating layer (not shown) can be set on the surface of the electrode 108 to prevent the electrode 108 from being oxidized during use. An insulating layer can be coated on the surface of each electrode 108, or a transparent insulating layer can be laid where the electrodes 108 are distributed. The material of the insulating layer is not limited, and any flexible material is acceptable.

[0050] Each electrode 108 corresponds to one functional layer 104 or two functional layers 104. When one electrode 108 corresponds to one functional layer 104, one end of the electrode 108 is electrically connected to the functional layer 104, and the other end is electrically connected to the controller. In this case, the controller can control whether the functional layer 104 is passed through the one electrode 108 alone, and the number of one electrode 108 corresponds to the number of one functional layer 104. When one electrode 108 corresponds to two functional layers 104, the two ends of the electrode 108 are electrically connected to one functional layer 104, and the middle part of the electrode 108 is electrically connected to the controller. In this case, the controller can control the two functional layers 104 through the one electrode 108, and the number of one electrode 108 corresponds to the number of a pair of functional layers 104. The numbering order of the plurality of electrodes 108 does not represent the position order thereof, that is, the positions of two electrodes 108 with adjacent numbers are not necessarily adjacent, and can be arranged adjacently or spaced apart. Since the numbering of the electrodes 108 corresponds to the numbering of the functional layers 104, it can be understood that the positions of two pairs of functional layers 104 with adjacent numbers or two functional layers 104 with adjacent numbers can be arranged adjacent to each other or at intervals. When applied, a voltage is cyclically applied between the two electrodes 108 in the manner of 1 and 2, 2 and 3, 3 and 4...K-1 and K, so that current is cyclically input to the two pairs of functional layers 104 or two functional layers 104 corresponding to every two electrodes 108, so as to achieve the purpose of cyclically stimulating the skin in sequence. The two pairs of functional layers 104 having adjacent numbers, such as 2 and 3, does not mean that the positions of the two pairs of functional layers are adjacent. The positions of the two pairs of functional layers 104 with adjacent numbers can be arbitrarily set according to actual needs. Please refer to Figure 3In this embodiment, one electrode 108 corresponds to a pair of functional layers 104, and the flexible mask 100 includes four pairs of functional layers 104, which are numbered 1, 2, 3, and 4. The positions of numbers 1, 2, 3, and 4 can be set arbitrarily, for example Figure 3 In application, the electrodes 108 are energized in a cycle of numbering the electrodes 108 as 1 and 2, 2 and 3, and 3 and 4, thereby sequentially or selectively generating microcurrents in the two pairs of functional layers 104 to sequentially or selectively stimulate the skin.

[0051] Each functional layer 104 may be a carbon nanotube layer. The carbon nanotube layer includes a large number of uniformly distributed carbon nanotubes, and the carbon nanotubes are tightly bound by van der Waals forces. The carbon nanotube layer may be a pure carbon nanotube layer including only carbon nanotubes. The thickness of the carbon nanotube layer is preferably 50 nanometers to 100 micrometers. The carbon nanotubes in the carbon nanotube layer include one or more of single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes. The carbon nanotubes may be pure carbon nanotubes, and pure carbon nanotubes refer to carbon nanotubes that do not contain other impurities on the surface, such as amorphous carbon, functional groups, etc. The diameter of the single-walled carbon nanotube is 0.5 nanometers to 50 nanometers, the diameter of the double-walled carbon nanotube is 1.0 nanometers to 50 nanometers, and the diameter of the multi-walled carbon nanotube is 1.5 nanometers to 50 nanometers. The carbon nanotube layer may include orderly arranged carbon nanotubes, and the carbon nanotubes are preferentially oriented and arranged along a fixed direction. The carbon nanotube layer may also include disordered and randomly arranged carbon nanotubes.

[0052] Preferably, the carbon nanotube layer is a self-supporting structure. The so-called "self-supporting structure" means that the carbon nanotube layer can maintain its own specific shape without being supported by a support body. The carbon nanotube structure of the self-supporting structure includes a plurality of carbon nanotubes, which attract each other through van der Waals forces to form a network structure, and make the carbon nanotube structure have a specific shape to form an integrated self-supporting carbon nanotube layer. Compared with a carbon nanotube layer that cannot be self-supporting, such as a carbon nanotube slurry layer, a self-supporting carbon nanotube layer has better flexibility. Experiments have shown that if a carbon nanotube slurry is brushed on the inside of the flexible mask 100 as a functional layer 104, after the carbon nanotube slurry is dried, the flexibility of the flexible mask 100 will be reduced due to the carbon nanotube slurry layer. Of course, the carbon nanotube slurry layer can also be used as the functional layer 104 of the present invention, and when it is used as the functional layer 104, the mask-type beauty instrument can also work.

[0053] Specifically, the carbon nanotube layer includes at least one carbon nanotube film or at least one carbon nanotube wire. It is understood that when the carbon nanotube layer includes a plurality of carbon nanotube films, the plurality of carbon nanotube films can be stacked. The carbon nanotube film is an ordered carbon nanotube film or a disordered carbon nanotube film. The disordered carbon nanotube film includes a plurality of disordered carbon nanotubes, where disorder means that the arrangement direction of the carbon nanotubes is irregular. The ordered carbon nanotube film means that the arrangement direction of most carbon nanotubes in the carbon nanotube film has a certain regularity. Specifically, the carbon nanotubes in the disordered carbon nanotube film can be further entangled with each other, and the carbon nanotube layer formed by the disordered carbon nanotubes is isotropic; the carbon nanotubes in the ordered carbon nanotube film are preferentially oriented and arranged in one direction or multiple directions. The carbon nanotube film can be a carbon nanotube drawn film, a carbon nanotube flocculated film or a carbon nanotube rolled film.

[0054] The carbon nanotube film is a carbon nanotube film obtained by pulling from a carbon nanotube array. The carbon nanotube layer may include one carbon nanotube film or two or more carbon nanotube films. The carbon nanotube film includes a plurality of carbon nanotubes preferentially oriented in the same direction and arranged parallel to the surface of the carbon nanotube film. The carbon nanotubes are connected end to end by van der Waals forces. Figure 4 and Figure 5 Each carbon nanotube film includes a plurality of continuous and directional carbon nanotube segments 143. The plurality of carbon nanotube segments 143 are connected end to end by van der Waals forces. Each carbon nanotube segment 143 includes a plurality of mutually parallel carbon nanotubes 145, and the plurality of mutually parallel carbon nanotubes 145 are tightly connected by van der Waals forces. The carbon nanotube segment 143 has any width, thickness, uniformity and shape. The thickness of the carbon nanotube film is 0.5 nanometers to 100 micrometers, and the width is related to the size of the carbon nanotube array from which the carbon nanotube film is drawn, and the length is not limited. For the carbon nanotube film and its preparation method, please refer to the Chinese patent application No. CN101239712A filed by Fan Shoushan et al. on February 9, 2007 and published on August 13, 2008, "Carbon Nanotube Film Structure and Preparation Method Thereof", applicants: Tsinghua University, Hongfujin Precision Industry (Shenzhen) Co., Ltd. To save space, it is only cited here, but all technical disclosures of the above application should also be regarded as part of the technical disclosures of the present application.

[0055] When the carbon nanotube layer includes more than two layers of carbon nanotube films, the multiple layers of carbon nanotube films are stacked or arranged in parallel. A cross angle α is formed between the preferentially oriented carbon nanotubes in two adjacent layers of carbon nanotube films, and α is greater than or equal to 0 degrees and less than or equal to 90 degrees (0°≤α≤90°). There is a certain gap between the multiple layers of carbon nanotube films or between adjacent carbon nanotubes in a carbon nanotube film, thereby forming a plurality of pores in the carbon nanotube layer, and the size of the pores is about less than 10 microns so that the matrix can penetrate into these pores.

[0056] The carbon nanotube flocculated membrane is a carbon nanotube membrane formed by a flocculation method, and the carbon nanotube flocculated membrane includes carbon nanotubes that are entangled and evenly distributed. The length of the carbon nanotubes is greater than 10 microns, preferably 200 to 900 microns. The carbon nanotubes are attracted and entangled with each other through van der Waals forces to form a network structure. The carbon nanotube flocculated membrane is isotropic. The carbon nanotubes in the carbon nanotube flocculated membrane are evenly distributed and irregularly arranged, forming a large number of pore structures with a pore size of less than about 10 microns. The length and width of the carbon nanotube flocculated membrane are not limited. Please refer to Figure 6 Since the carbon nanotubes in the carbon nanotube flocculated film are entangled with each other, the carbon nanotube flocculated film has good flexibility and is a self-supporting structure that can be bent and folded into any shape without breaking. For the carbon nanotube flocculated film and its preparation method, please refer to the Chinese published patent application No. CN101284662A "Preparation method of carbon nanotube film" filed by Fan Shoushan et al. on April 13, 2007 and published on October 15, 2008. The applicants are Tsinghua University and Hongfujin Precision Industry (Shenzhen) Co., Ltd. In order to save space, only this is cited, but all technical disclosures of the above application should also be regarded as part of the technical disclosures of the present application.

[0057] The carbon nanotube rolled film is a carbon nanotube film formed by rolling a carbon nanotube array. The carbon nanotube rolled film includes uniformly distributed carbon nanotubes, and the carbon nanotubes are preferentially oriented and arranged in the same direction or in different directions. The carbon nanotubes can also be isotropic. The carbon nanotubes in the carbon nanotube rolled film partially overlap each other, and are attracted to each other by van der Waals forces and tightly combined, so that the carbon nanotube layer has good flexibility and can be bent and folded into any shape without breaking. And because the carbon nanotubes in the carbon nanotube rolled film are attracted to each other by van der Waals forces and tightly combined, the carbon nanotube rolled film is a self-supporting structure. The carbon nanotube rolled film can be obtained by rolling a carbon nanotube array. The carbon nanotubes in the carbon nanotube rolled film form an angle β with the surface of the growth substrate forming the carbon nanotube array, wherein β is greater than or equal to 0 degrees and less than or equal to 15 degrees (0≤β≤15°). The angle β is related to the pressure applied to the carbon nanotube array. The greater the pressure, the smaller the angle. Preferably, the carbon nanotubes in the carbon nanotube rolled film are arranged parallel to the growth substrate. Depending on the rolling method, the carbon nanotubes in the carbon nanotube rolled film have different arrangements. When rolled in the same direction, the carbon nanotubes are preferentially oriented along a fixed direction. Please refer to Figure 7 , when rolled in different directions, the carbon nanotubes are preferentially oriented and arranged in different directions. When the carbon nanotube array is rolled vertically from the top of the carbon nanotube array, the carbon nanotube rolled film is isotropic. The length of the carbon nanotubes in the carbon nanotube rolled film is greater than 50 microns. There is a certain gap between adjacent carbon nanotubes in the carbon nanotube rolled film, thereby forming a plurality of pores in the carbon nanotube rolled film, and the size of the pores is about less than 10 microns. For the carbon nanotube rolled film and its preparation method, please refer to the Chinese published patent application No. CN101314464A "Method for Preparing Carbon Nanotube Film" filed by Fan Shoushan et al. on June 1, 2007 and published on December 3, 2008, applicants: Tsinghua University, Hongfujin Precision Industry (Shenzhen) Co., Ltd.

[0058] When the carbon nanotube layer includes a plurality of carbon nanotube wires, the plurality of carbon nanotube wires may be arranged parallel to each other, side by side or crosswise to form a two-dimensional carbon nanotube layer or woven together to form a two-dimensional carbon nanotube layer. Figure 8 , which is a carbon nanotube layer composed of a plurality of cross-arranged carbon nanotube lines. Fig. 9 , which is a carbon nanotube layer consisting of a plurality of carbon nanotube lines interwoven with each other. In addition, see Fig.10When the carbon nanotube layer includes a carbon nanotube wire, the carbon nanotube wire can be bent and coiled into a two-dimensional carbon nanotube layer. The carbon nanotube wire can be a non-twisted carbon nanotube wire or a twisted carbon nanotube wire. The non-twisted carbon nanotube wire is obtained by treating a carbon nanotube film with an organic solvent. The non-twisted carbon nanotube wire includes a plurality of carbon nanotubes arranged along the length direction of the carbon nanotube wire. Preferably, the carbon nanotubes are connected end to end.

[0059] The non-twisted carbon nanotube wire is obtained by treating a carbon nanotube film with an organic solvent.

[0061] The carbon nanotube layer has better flexibility than the flexible layer and / or the flexible porous layer. When the carbon nanotube layer is used as a functional layer in a flexible facial mask, the flexibility of the entire flexible facial mask will not be reduced due to the setting of the functional layer; the carbon nanotube layer has great strength, and the carbon nanotube layer will not be damaged no matter how the flexible facial mask is bent or pulled.

[0062] The second embodiment of the present invention provides a facial mask type beauty instrument, which includes a flexible facial mask and a controller. Fig.13 , the flexible mask 200 comprises: a flexible layer 202; a flexible porous layer 206, wherein the flexible layer 202 and the flexible porous layer 206 are stacked; and a plurality of functional layers 204, wherein the plurality of functional layers 204 are arranged between the flexible layer 202 and the flexible porous layer 206; the plurality of functional layers 204 are symmetrically distributed or regularly distributed, wherein each pair of functional layers 204 in the plurality of functional layers 204 is electrically connected to an electrode 208. The mask-type beauty instrument provided in this embodiment is substantially the same as that in the first embodiment, except that the number and distribution position of the functional layers 204, and the number of electrodes 208. In this embodiment, the functional layers 204 include 12, i.e., 6 pairs of functional layers are respectively distributed on the cheeks and forehead of the flexible mask.

[0063] The third embodiment of the present invention provides a facial mask type beauty instrument, which includes a flexible facial mask and a controller. Fig.14 The flexible mask 300 includes: a flexible layer 302; a flexible porous layer 306, wherein the flexible layer 302 and the flexible porous layer 306 are stacked; and a plurality of functional layers 304, wherein the plurality of functional layers 304 are arranged between the flexible layer 302 and the flexible porous layer 306; the plurality of functional layers 304 are symmetrically distributed or regularly distributed, wherein each of the plurality of functional layers 304 is electrically connected to an electrode 308, that is, the functional layer 304 and the electrode 308 are in a one-to-one correspondence. The plurality of functional layers 304 are defined to include N (N=1, 2, 3, 4, 5...) functional layers 304, wherein the N functional layers 304 are electrically connected to N (N=1, 2, 3, 4, 5...) electrodes 308. The facial mask type beauty instrument provided in this embodiment is basically the same as that in the first embodiment, except that the functional layers 304 and the electrodes 308 are arranged in a one-to-one correspondence, that is, the number of the functional layers 304 is the same as the number of the electrodes 308. The controller controls only one functional layer 304 by controlling one electrode 308. This arrangement method is more conducive to the selective action of the functional layer 304 on the human face.

[0065] First, the facial mask type beauty instrument is provided, and a beauty liquid or other liquid to be applied to a human face is soaked on a flexible facial mask of the facial mask type beauty instrument;

[0066] Secondly, the flexible mask of the facial mask beauty instrument is attached to the human face;

[0067] Again, turn on the controller, select the function button on the controller, input current into the functional layer in the flexible mask, and stimulate the skin of the face.

[0068] The controller is provided with a plurality of function buttons for controlling the flexible mask. Each function button can control the current size, the frequency of the current, the position of the input current, etc., so as to control the functional layer inside the flexible mask and realize different functions. The flexible mask can be movably connected to the controller. The flexible mask has a reserved access port at the window position on the flexible layer or the flexible porous layer, and the controller is connected to the flexible mask through the access port. The flexible mask 100 can be replaced as needed. The flexible mask 100 can also be washed to achieve the effect of repeated use.

[0069] Each electrode corresponds to a functional layer or a pair of functional layers. When an electrode corresponds to a functional layer, one end of the electrode is electrically connected to the functional layer, and the other end is electrically connected to the controller. In this case, the controller can control whether the functional layer is passed through the current through the electrode alone, and the number of the electrode corresponds to the number of the functional layer. When an electrode corresponds to two functional layers, the two ends of the electrode 108 are electrically connected to a functional layer respectively, and the middle part of the electrode is electrically connected to the controller. In this case, the controller can control the two functional layers through the electrode, and the number of the electrode corresponds to the number of the pair of functional layers. The numbering order of the multiple electrodes does not represent their position order, that is, the positions of two electrodes with adjacent numbers are not necessarily adjacent. Since the number of the electrode corresponds to the number of the functional layer, it can be understood that the positions of two pairs of functional layers with adjacent numbers or two functional layers with adjacent numbers can be arranged adjacently or at intervals. The voltage is cyclically applied between the two electrodes in the manner of 1 and 2, 2 and 3, 3 and 4...K-1 and K, so as to cyclically input current to the two pairs of functional layers or two functional layers corresponding to each two electrodes, so as to achieve the purpose of cyclically stimulating the skin in sequence. Each pair of electrodes can be powered on for a period of time, then stay for a period of time, and then the next pair of electrodes can be powered on. That is, the cycle time of each pair of electrodes is the sum of the power-on time and the stay time. The power-on voltage can be set as needed. Preferably, the voltage during power-on is 20 to 36 volts and the voltage frequency is 50 to 100 Khz. When one electrode corresponds to a pair of functional layers, applying voltage to a pair of electrodes can input current to the two pairs of functional layers. When one electrode corresponds to one functional layer, applying voltage to a pair of electrodes can input current to the two functional layers.

[0070] Take the facial mask type beauty instrument provided in the first embodiment as an example. The four pairs of functional layers in the flexible facial mask 100 are numbered as follows: Figure 3 B. Turn on the current stimulation button on the controller, and cycle in the order of 1 and 2, 2 and 3, 3 and 4, 4 and 5, input current to the functional layer 104 through each pair of electrodes 108, and stimulate the skin with current cycle. In this embodiment, the power-on time of each pair of electrodes 108 is 1s, and the dwell time is 1s, that is, with a cycle of 0.2s, first power on for 0.1s, then stop for 0.1s, and so on. Among them, within 0.1s of power on, the voltage range of the electrode 108 can be adjusted between 20-36V, and the frequency is 90Khz.

[0071] Compared with the prior art, the facial mask-type beauty instrument provided by the present invention has the following advantages: First, it can be directly attached to the face of a person without the need for hand support, thus freeing the hands of the user. Second, by controlling the circuit through the controller, selective stimulation of the skin on the face can be achieved, and the parts that need stimulation can be selected more accurately without causing facial asymmetry. Third, a carbon nanotube layer is used as a functional layer, and the carbon nanotube layer has better flexibility than the flexible layer and / or the flexible porous layer. The flexibility of the entire flexible mask will not be reduced due to the setting of the functional layer. The flexible mask can be better attached to the face of a person, and the user comfort is higher. Fourth, a carbon nanotube layer is used as a functional layer, and the strength of the carbon nanotube layer is relatively large. No matter how the flexible mask is bent, pulled, or washed, the carbon nanotube layer will not be damaged, and the flexible mask has a longer service life.

[0072] In addition, those skilled in the art may also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included in the scope of protection required by the present invention.
