Description

Technical Field

[0001] The utility model relates to the technical field of water light instruments, in particular to a water light instrument. Background Art

[0002] The stratum corneum is the natural protective layer of human skin. It is about 10-40μm thick and is a layer of dead tissue. Although it has no blood vessels and nerves, it is a controlled release layer for the transdermal absorption of essences. If the active ingredients in the essence applied to human skin cannot penetrate the stratum corneum, or only a very small part of it can penetrate the stratum corneum, it will directly affect the beauty effect.

[0003] The microneedle wafer is a special tool for nano-penetration developed based on the structure of human skin. It is carved from single-crystal silicon using nanotechnology. The surface of the microneedle wafer is a series of microneedle arrays that can pierce the stratum corneum and open up channels to the dermis, allowing the essence to penetrate into the dermal cells more easily.

[0004] At present, the problem with beauty products on the market that have microneedle chips, namely hyaluronic acid devices, is that the degree of stimulation when the microneedle chips come into contact with human skin is difficult to control, and there are individual differences in the perception of microneedle stimulation, which can cause some users to feel uncomfortable with the microneedle stimulation.

[0005] Therefore, it is necessary to improve the existing technology.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, ordinary technicians in this field can know that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0054] In the description of the present application, it should be understood that, unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as those commonly understood by those skilled in the art of the present application. In addition, any terminology used is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0055] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0056] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0057] In view of the above-mentioned defects of the existing water light instrument, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation, hoping to create a technology that can solve the defects in the existing technology and make the water light instrument more practical. After continuous research and design, and after repeated trial samples and improvements, the present utility model with real practical value was finally created.

[0058] Please refer to Figure 1-2 The present utility model provides a water light instrument, comprising a housing 1 and a microneedle device 2; wherein,

[0059] The microneedle device 2 is elastically and movably arranged on the housing 1 via an elastic member 3 .

[0060] It should be noted that the microneedle device 2 includes microneedle wafers and other forms of microneedles. When the water light needle head is in use, the microneedles of the microneedle device 2 can stimulate the skin after contacting the skin, forming fine skin channels on the skin surface so that the essence can penetrate into the skin to achieve a beauty effect. In order to reduce the discomfort caused by microneedle stimulation, the present embodiment sets an elastic member 3 between the microneedle device 2 and the housing 1, so that the microneedle device 2 moves relative to the skin after contacting the skin (at the same time, the microneedle device 2 moves relative to the housing 1 under the elastic action of the elastic member 3), playing a role of buffering and unloading force, so that the discomfort caused by the microneedle device 2 to the skin can be alleviated, thereby improving the user experience.

[0061] Exemplarily, the elastic member 3 may be a spring.

[0062] Please refer again Figure 2 In this embodiment, further, the water light instrument also includes a control mechanism 4 and a driving mechanism 5;

[0063] The control mechanism 4 is disposed in the housing 1 and is electrically connected to the driving mechanism 5;

[0064] The driving mechanism 5 is disposed in the housing 1 and connected to the microneedle device 2 for driving the microneedle device 2 to move.

[0065] It should be noted that, since the microneedle device 2 needs to reciprocate in contact with the skin to better promote the absorption of the essence, the provision of the driving mechanism 5 is necessary, aiming to drive the microneedle device 2 to move through the driving mechanism 5 and ensure the stable reciprocating motion of the microneedle device 2.

[0066] In this embodiment, the driving mechanism 5 may include a driving device, and the driving device alone can provide reciprocating driving force for the microneedle device 2, or the driving mechanism 5 may include a driving device and an elastic reset member, and the two cooperate with each other to realize the reciprocating drive of the microneedle device 2, that is, the microneedle device 2 moves outward a certain distance under the drive of the driving device, and after the driving force of the driving device is withdrawn, the microneedle device 2 will return under the action of the elastic reset member, thereby realizing reciprocation.

[0067] Exemplarily, the elastic return member may be a spring.

[0068] It can be understood that no matter which of the above reciprocating drive settings is used, compared with the user manually operating the hyaluronic acid analyzer to make the microneedle device 2 reciprocate on the human facial skin, the automated method can provide a more uniform and stable reciprocating drive, while eliminating the manual reciprocating movement operation, thereby improving the user experience.

[0069] It is understandable that the control mechanism 4 is used to control the start and stop of the driving mechanism 5, and it should at least include a circuit board, which is electrically connected to the driving mechanism 5, and may also include a button, which is electrically connected to the circuit board.

[0070] Exemplarily, the buttons may include a power button and a gear button. The power button can output a power on / off command, while the gear button can adjust the movement rate.

[0071] Please refer again Figure 1-2 , and combined with reference Figure 3-5 In this embodiment, further, the housing 1 includes a main body 101 and a head 102;

[0072] The microneedle device 2 is elastically and movably arranged on the head 102 through the elastic member 3;

[0073] The driving mechanism 5 is disposed in the main body 101 and connected to the head 102 for driving the head 102 to move.

[0074] It should be noted that in order to adapt the driving mechanism 5 to drive the movement of the microneedle device 2, the shell 1 needs to be composed of two parts that can move with each other, namely, the main body 101 and the head 102, and then the driving mechanism 5 is set in the main body 101, and the microneedle device 2 is set in the head 102.

[0075] Optionally, the main body 101 is in a curved arc shape, so that the user can hold it easily without getting tired or slipping.

[0076] In this embodiment, further, one of the main body 101 and the head 102 is provided with a mounting opening 103 , and the other can be inserted into the mounting opening 103 .

[0077] It should be noted that the design of the mounting port 103 can ensure that the connection between the head 102 and the main body 101 is stable and reliable. When the head 102 or the main body 101 is inserted into the mounting port 103, the contact area between the two increases, and the interference area increases, thereby providing better stability and support. This helps to ensure that the water light instrument will not fall off during use, ensuring safe use. It can be understood that the head 102 or the main body 101 is inserted into the mounting port 103, which should include a partial structure of the head 102 or the main body 101 inserted into the mounting port 103.

[0078] Although the present embodiment specifies that the installation opening 103 can be provided in the main body 101 or in the head 102, in general, the installation opening 103 is preferably provided in the main body 101 which has a larger volume and more abundant layout space, such as Figure 5 shown.

[0079] Please refer again Figure 2 , and combined with reference Figure 6 , in this embodiment, the water light instrument further includes a mounting base 104;

[0080] The mounting seat 104 is elastically and movably connected to the head 102 via the elastic member 3;

[0081] The microneedle device 2 is disposed on the mounting seat 104 .

[0082] It should be noted that in order to avoid the problem of poor structural stability caused by the elastic member 3 leaking into the air and being easily affected by the external environment or human factors, the head 102 and the mounting seat 104 are designed to be movable relative to each other in this embodiment, so that the elastic member 3 can be hidden between the mounting seat 104 and the head 102, while satisfying the requirement that the microneedle device 2 and the mounting seat 104 can move relative to the head 102.

[0083] In this embodiment, further, the water light instrument also includes an atomization component;

[0084] The atomizing assembly is disposed in the housing 1 and is used for atomizing and spraying the liquid.

[0085] It should be noted that when using a water light instrument for beauty and skin care, essence is often sprayed on the skin first, and then the microneedle device 2 is used to form fine skin channels on the surface of the facial skin. Therefore, the water light instrument of this embodiment further includes an atomization component for spraying essence on the skin.

[0086] In addition, considering that compared with essence in liquid form, essence in aerosol form can better penetrate into the skin and be absorbed by the skin, and can also better control the amount sprayed each time and the uniformity of spraying, so as not to cause waste, the atomization component provided in this embodiment is used to atomize the essence before it reaches the facial skin of the human body.

[0087] Please refer to Figure 7 In this embodiment, the atomization assembly includes an atomization mechanism 6 and an air supply mechanism 7;

[0088] The gas supply mechanism 7 is disposed in the main body 101 and is used to deliver gas to the atomization mechanism 6;

[0089] The atomizing mechanism 6 is disposed in the head 102 and is used to atomize and spray liquid, such as essence, using gas.

[0090] It should be noted that the atomizing mechanism 6 is connected to the gas supply mechanism 7 through an air pipeline to ensure that the gas provided by the gas supply mechanism 7 can be stably and efficiently transmitted to the atomizing mechanism 6. The gas supply mechanism 7 can be a small air pump or a compressed gas storage device, which can provide gas with sufficient pressure and flow to the atomizing mechanism 6 when needed.

[0091] Please refer again Figure 7 , and combined with reference Figure 8 In this embodiment, the atomization mechanism 6 includes an atomization chamber 601, the atomization chamber 601 is provided with an air inlet 602, an air outlet 603, a liquid inlet 604 and a liquid outlet 605, and a gas flow channel 606 and a liquid flow channel 607 are provided in the atomization chamber 601;

[0092] One end of the liquid flow channel 607 is connected to the liquid inlet 604, and the other end of the liquid flow channel 607 is connected to the liquid outlet 605;

[0093] One end of the gas flow channel 606 is connected to the gas inlet 602, and the other end of the gas flow channel 606 is connected to the gas outlet 603;

[0094] The air inlet 602 is communicated with the air supply mechanism 7 , and the air outlet 603 surrounds part or all of the liquid outlet 605 .

[0095] It should be noted that this embodiment is based on the principle of gas path atomization, by providing high-speed gas through the gas supply mechanism 7, and then conveying the high-speed gas into the gas flow channel 606, so as to utilize the high-speed gas to form a negative pressure at the gas outlet 603, which can drive the essence in the liquid flow channel 607 to be ejected from the liquid outlet 605, and make the ejected essence become small molecule aerosol after combining with the high-speed gas surrounding it, so as to realize the atomization of the essence. It can be understood that the gas outlet 603 surrounds part or all of the liquid outlet 605, including that the gas outlet 603 is arranged on the peripheral side of the liquid outlet 605, at this time, the gas outlet 603 can be arranged at only one or more, and also includes that the gas outlet 603 is annular and arranged around the liquid outlet 605.

[0096] It is understandable that the atomized essence can be introduced into the dermis, opening millions of channels in the epidermis of several square millimeters without damaging the epidermis of the skin, allowing the active ingredients of the essence to effectively penetrate the skin, stimulate collagen proliferation and cell regeneration, repair aging cells, and improve the beauty and skin care effects.

[0097] Please refer again Figure 7-8 In this embodiment, the mounting seat 104 is provided with an atomization outlet 8, and the atomization outlet 8 is connected to the liquid outlet 605;

[0098] An avoidance hole 9 is provided at a position of the microneedle device 2 corresponding to the atomization outlet 8 .

[0099] It should be noted that, since the area where the microneedle device 2 is located needs to cover the area where the atomization outlet 8 is located, and the microneedle device 2 is designed to have an avoidance hole 9 at the position corresponding to the atomization outlet 8, the atomized essence can be sprayed out from the atomization outlet 8 and the avoidance hole 9 in turn, and finally reaches the skin stimulated by the microneedle device 2, so that the mist outlet position is close to the microneedle device. On the one hand, it can make the size of the water light instrument smaller for users to hold and store. On the other hand, when the microneedle device stimulates human skin, the mist essence can enter the skin in a timely and rapid manner, thereby further improving the absorption effect of the essence. On the other hand, more atomized essence can be sprayed onto the skin area acted on by the microneedle device, which can further promote the penetration of the essence and reduce the residue through microneedle penetration promotion. On the other hand, the effective area of ​​the atomized essence and the microneedle device acting on the skin can be the same, thereby greatly improving the skin care efficiency.

[0100] Optionally, the avoidance hole 9 is opened at the center of the microneedle device 2, and the avoidance hole 9 is coaxially arranged with the atomization outlet 8 to ensure that the skin area stimulated once by the microneedle device 2 can evenly absorb the atomized essence.

[0101] Please refer again Figure 9-10 In this embodiment, the water light instrument further includes a protective cover 10;

[0102] The protective cover 10 is disposed on the position of the head 102 corresponding to the microneedle device 2 .

[0103] It should be noted that, by providing the protective cover 10, when the hyaluronic acid analyzer is not in use, especially when the head 102 is removed from the main body 101, the microneedle device 2 can be protected from being contacted by external objects to avoid being damaged and the beauty effect being affected.

[0104] Exemplarily, the protective cover 10 is generally a snap cover in a cylindrical shape, which is adapted to the shape of the head 102 .

[0105] Please refer again Fig.10 , and combined with reference Fig.11 In this embodiment, a silicone pad 11 is disposed inside the protective cover 10 .

[0106] It should be noted that the silicone pad 11 has good shockproof performance, which can effectively reduce the vibration when the hyaluronic acid needle device falls or is hit, thereby preventing the microneedle device 2 from being damaged due to strong vibration.

[0107] It is understandable that in order to better protect the microneedle device 2, the silicone pad 11 has a hollow position design, which corresponds to the microneedle device 2, so as to protect the microneedle device 2 from strong vibration while not exerting pressure on the microneedle device 2 due to contact with the microneedle device 2.

[0108] Please refer again Fig.10 , and combined with reference Fig.11 , in this embodiment, an anti-clogging column 12 is provided in the protective cover 10;

[0109] The anti-clogging column 12 passes through the avoidance hole 9 and the atomization outlet 8 and is inserted into the liquid outlet 605 .

[0110] It should be noted that the diameter of the liquid outlet 605 is very small. After use, there is often unsprayed essence at the liquid outlet 605, so the essence is very easy to condense and accumulate at the liquid outlet 605, causing the liquid outlet 605 to be blocked. Once blocked, it is very inconvenient to clean. For this reason, this embodiment provides an anti-blocking column 12 in the protective cover 10. When not in use, by covering the protective cover 10, the anti-blocking column 12 passes through the avoidance hole 9 and the atomization outlet 8 and is inserted into the liquid outlet 605, which can prevent the condensation and accumulation of the essence, thereby avoiding the blockage of the liquid outlet 605.

[0111] It is understandable that the specific function of other structural designs in the hyaluronic acid meter, such as batteries, display screens, charging ports, etc., is to ensure the normal operation of various functions of the hyaluronic acid meter. In view of the fact that these structural designs have been implemented in many existing technologies and are not the focus of this design, they will not be elaborated in depth here.

[0112] Although the terms such as housing, microneedle device, elastic member, control mechanism, driving mechanism, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0113] The utility model provides a hyaluronic acid instrument, comprising a shell and a microneedle device. The microneedle device is designed to be elastically and movably arranged on the shell through an elastic member, so that when the microneedle device contacts human skin, it can move relative to the shell under the elastic action of the elastic member, and also move relative to the human skin, so as to remove part of the external force and achieve a buffering effect, thereby reducing the discomfort caused by microneedle stimulation and improving the user experience.
