Description

Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a beauty instrument. Background Technology

[0002] A beauty device is an electronic device with multiple functions designed to provide various beauty and care for the skin. Different types of beauty devices have different functions, including cleansing, massage, firming, and skincare product delivery. Among them, a hyaluronic acid device is a beauty device that injects nutrients, moisturizers, and vitamins into the skin's surface to change the skin's moisture content, radiance, and overall appearance, and is used to improve skin texture, reduce fine lines, and brighten skin tone.

[0003] With the development of technology and the change of consumer views, water-light beauty devices have gradually entered thousands of households. In related technologies, beauty devices mainly include components such as microcrystalline tube fixing devices, beauty device injection devices, connecting air tubes, and beauty device controllers. With the beauty device injection device installed, the beauty device starts working when it is placed on the surface of human skin, spraying essence into the skin. When the beauty device leaves the body, it automatically stops working.

[0004] According to relevant technologies, current beauty devices have the function of automatically spraying essence to enhance skin care effects. However, there are still limitations in the application of essence by current beauty devices. Specifically, when applying essence to a specific area of ​​skin, the device is easily affected by the operation, causing it to deviate during use and thus affecting the accuracy of essence application. There is also a possibility that the essence may be sprayed into the eyes or nostrils. Therefore, it is necessary to improve the existing technology.

[0045] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0047] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0048] The following is in conjunction with the appendix Figures 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0049] Reference Figure 1 , Figure 2 as well as Figure 3A beauty device includes a beauty device body 1, a beauty head 31, an air supply unit 14, and a negative pressure mechanism 5. The beauty head 31 is located at one end of the beauty device body 1 and has a negative pressure cavity 2 that communicates with the outside. The beauty head 31 includes an adsorption element 3123 located in the negative pressure cavity 2. The adsorption element 3123 has a porous structure for retaining essence.

[0050] As shown in the structure above, refer to Figure 2 and Figure 3 The air supply unit 14 is connected to the liquid storage chamber 6 through an air inlet channel 1005. The liquid storage chamber 6 is used to store the essence. The liquid storage chamber 6 is connected to the adsorption element 3123 through an outlet channel 1004. The air supply unit 14 pressurizes the air into the liquid storage chamber 6 through the air inlet channel 1005, and draws the essence from the liquid storage chamber 6 to the adsorption element 3123 and applies it to the skin.

[0051] Continue to refer to Figure 2 and Figure 3 The negative pressure mechanism 5 is connected to the negative pressure chamber 2. The negative pressure mechanism 5 is used to extract air so that a negative pressure area that adsorbs the skin is formed in the negative pressure chamber 2.

[0052] In the above scheme, by activating the negative pressure mechanism 5, the negative pressure mechanism 5 extracts air from the negative pressure chamber 2 to form a negative pressure area that can adsorb the skin, thereby adsorbing and positioning the skin. Under this condition, the beauty device is less likely to deviate. At the same time, driven by the air supply unit 14 and guided by the air intake channel 1005, the airflow is forced into the liquid storage chamber 6, causing the essence to be expelled and transferred to the liquid outlet 1002 through the liquid outlet channel 1004, thus achieving the liquid dispensing effect. At this time, the adsorption element 3123 adsorbs the essence to prevent the essence from flowing back into the negative pressure mechanism 5, thereby achieving precise application of the essence to the adsorbed skin and preventing the essence from splashing into the eyes or nostrils.

[0053] Furthermore, referring to Figure 3 and Figure 4 To optimize the beauty experience, the vibration mechanism 9 includes a vibration connector 92 and a vibration motor 91. The vibration mechanism 9 includes a vibration motor 91, which is located in the beauty device body 1. It can usually be directly installed inside the beauty device body 1. In this embodiment, an eccentric vibration motor 91 structure is adopted. The eccentric vibration motor 91 has the functions of compact size and stable vibration, which can well meet the required working conditions.

[0054] Furthermore, the vibration connector 92 is disposed on the beauty device body 1 and is connected to the vibration motor 91. The beauty head 31 is disposed on the vibration connector 92. When connecting the vibration motor 91 and the vibration connector 92, a transmission rod is also disposed on the vibration connector 92. The vibration connector 92 is connected to the output shaft of the vibration motor 91 via the transmission rod, and the periphery of the vibration connector 92 slides against the inner peripheral wall of the beauty device body 1, allowing the vibration connector 92 to slide back and forth along the length of the beauty device body 1. Driven by the vibration motor 91, the vibration connector 92 vibrates back and forth, thereby causing the beauty head 31 to vibrate back and forth, massaging the skin and optimizing the beauty experience.

[0055] Furthermore, referring to Figure 5 To optimize the overall compactness of the beauty device, the device also includes a main body 32 and a container 61. The beauty head 31 is mounted on the main body 32. Typically, the beauty head 31 can be mounted on the main body 32 by a fixed connection or a detachable connection. When the beauty head 31 is detachably mounted on the main body 32, the beauty head 31 can be disassembled and replaced relative to the main body 32, so as to facilitate the regular replacement of the beauty head 31 and keep the beauty head 31 hygienic and clean.

[0056] In addition, when the beauty head 31 is fixed to the main body 32, the beauty head 31 and the main body 32 form a modular structure to facilitate one-time production. In this embodiment, the beauty head 31 and the main body 32 are fixedly connected.

[0057] The container 61 can be a vial, a soft bag, or other container capable of storing essence. In this embodiment, a vial structure with higher hygiene standards is selected. In this case, a liquid storage chamber 6 is formed inside the container 61. The container 61 is detachably mounted on the main body 32. The container 61 is a component that can be sold or used independently of the beauty device. It is detachably connected to the beauty device by means of plugging or unplugging. After the container 61 is inserted into the beauty device, the liquid outlet channel 1004 can connect the container 61 and the beauty head 31.

[0058] In some other embodiments, a reservoir 6 for storing essence can be built into the inside of the beauty device, and the liquid outlet channel 1004 can be directly connected to the reservoir 6 to the beauty head 31.

[0059] Furthermore, looking back Figure 2To enable plug-in connection, a connecting part 33 is provided on the main body 32. The connecting part 33 includes a columnar or conical plug-in part, which can be easily inserted into the container 61. At the same time, an outlet 331 and an air inlet 332 are respectively provided through the plug-in part. The air inlet channel 1005 and the liquid outlet channel 1004 are integrated inside the main body 32. The air inlet channel 1005 and the liquid outlet channel 1004 can adopt a flexible hose structure. The two ends of the air inlet channel 1005 are respectively connected to the connecting part 33 and the air supply unit 14, and the air inlet channel 1005 is connected to the air inlet 332. At this time, the air supply unit 14 can pressurize the air into the liquid storage chamber 6 through the air inlet channel 1005 and the air inlet 332.

[0060] In addition, the two ends of the liquid outlet channel 1004 are connected to the connecting part 33 and the beauty head 31 respectively, and the liquid outlet channel 1004 is connected to the outlet 331. At this time, after the gas enters the liquid storage chamber 6, the essence can flow through the outlet 331 and the liquid outlet channel 1004 to the adsorption element 3123 to realize the liquid outlet process.

[0061] Based on this, the main body 32 can be fixedly or detachably mounted on the vibration mechanism 9. Specifically, the main body 32 is connected to the vibration connector 92. At this time, the vibration mechanism 9 can drive the beauty head 31 to vibrate reciprocally via the main body 32. While achieving a vibration experience, this further enhances the compactness of the structure, and the use of a container 61 structure makes it easy for the user to observe the remaining essence volume. The user experience is thus improved.

[0062] Optional, refer to Figure 2 as well as Figure 4 The vibration connector 92 has a sleeve-shaped structure, and one end of the vibration connector 92 is open. The outline and size of the opening of the vibration connector 92 are adapted to the main body 32. At this time, the main body 32 can be inserted and removed onto the vibration connector 92 to achieve structural positioning. Then, a spring-loaded structure is set between the two to achieve disassembly and connection.

[0063] Reference Figure 1 and Figure 2 When the main body 32 and the vibration connector 92 are fixedly connected to each other, the vibration connector 92 and the main body 32 can also be housed inside the beauty device body 1 to further optimize the structural compactness. During installation, a first clearance opening 101 is first provided through one side of the beauty device body 1, combined with... Figure 4Furthermore, the vibration connector 92 is provided with a second clearance opening 921 corresponding to the first clearance opening 101. The first clearance opening 101 and the second clearance opening 921 are used to expose the main body 32 and the connecting part 33 located thereon. The first clearance opening 101 and the second clearance opening 921 play a clearance role so that the container 61 can be disassembled and assembled through the first clearance opening 101 and the second clearance opening 921. With this setting, the structural compactness is optimized and improved.

[0064] Furthermore, refer to again Figure 3 When the main body 32 and the vibration connector 92 are disassembled, an installation port 102 can be opened through one end of the beauty device body 1. At this time, the main body 32 and the beauty head 31 can be disassembled at the same time for regular replacement, reducing the possibility of essence remaining in the liquid outlet channel 1004 and the air inlet channel 1005, making it more hygienic and optimizing the skin care environment.

[0065] Understandably, referring to Figure 2 and Figure 3 The air supply unit 14 can be an air pump structure, which is defined here as liquid outlet air pump 141. The liquid outlet air pump 141 is connected to the liquid outlet channel 1004 through a pipe, which can achieve the effect of air supply and liquid outlet. In addition, when the main body 32 and the vibration connector 92 are disassembled and reassembled, in order to ensure the smooth flow of air, a first connecting part 111 can be provided on the vibration connector 92 and a second connecting part 112 can be provided on the main body 32. Both the first connecting part 111 and the second connecting part 112 are provided with connecting channels, and the first connecting part 111 and the second connecting part 112 are set to a connection relationship that can be interlocked, which can achieve a positioning effect. Under the action of the connecting channels, the air path of the main body 32 can be kept unobstructed before and after disassembly and assembly.

[0066] Reference Figure 3 and Figure 6 To achieve the adsorption effect, in this embodiment, the negative pressure mechanism 5 includes a negative pressure pump 51 and a solenoid valve 52. The negative pressure pump 51 is fixedly installed inside the beauty device body 1 and is connected to the negative pressure chamber 2 through a negative pressure channel 4. In this embodiment, the negative pressure channel 4 is located inside the main body 32 and has a tubular structure, preferably a rigid pipe. Rigid pipes are not easily deformed and can perform negative suction more smoothly.

[0067] One end of the negative pressure channel 4 is connected to the main body 32 and has an opening on the main body 32. At the same time, the opening end of the negative pressure channel 4 on the main body 32 is connected to the negative pressure pump 51 in the negative pressure mechanism 5. Furthermore, the other end of the negative pressure channel 4 is connected to the beauty head 31. Correspondingly, a through hole can be provided in the beauty head 31, which is connected to the negative pressure channel 4 and the negative pressure cavity 2 respectively. At this time, the negative pressure pump 51 can draw air from the negative pressure cavity 2 through the negative pressure pipe.

[0068] Furthermore, the solenoid valve 52 is also connected to the negative pressure channel 4. In specific settings, a multi-way valve structure can be set between the negative pressure pump 51 and the solenoid valve 52. First, the negative pressure pump 51 and the solenoid valve 52 are connected to the multi-way valve through pipes. Then, an integrated pipe is set on the multi-way valve, and the air path is connected by connecting the integrated pipe to the negative pressure channel 4. The solenoid valve 52 is used to replenish gas into the negative pressure channel 4 to break the negative pressure state in the negative pressure chamber 2, allowing the user to smoothly remove the beauty device from the skin without causing damage.

[0069] Reference Figure 6 To achieve the desired cosmetic effect, the beauty head 31 mainly includes a core body 31a and an adsorption sleeve 31b. The core body 31a mainly includes a core seat 311. Inside the core seat 311, there is a core tube 8 connected to the liquid outlet channel 1004. The other end of the core tube 8 extends to the outermost side of the core body 31a. The adsorption element 3123 is located on the outside of the core body 31a and covers the opening of the core tube 8. The porous structure of the adsorption element 3123 forms the liquid outlet 1002.

[0070] In this configuration, the serum can flow from the outlet channel 1004 through the core tube 8 into the adsorption element 3123. Under the effect of vibration, the serum can be directly applied to the skin through the adsorption element 3123, thus achieving the effect of serum dispensing.

[0071] Optionally, the adsorption element 3123 can be a component with many pores, such as a sponge block, a porous silicone block, or a porous ceramic block. These materials have a strong liquid absorption capacity due to their porous structure. They can absorb and retain a large amount of essence, allowing the essence to be delivered more evenly and continuously during the delivery process, without affecting the effect due to instantaneous changes in flow rate. In addition, soft materials such as sponge blocks and porous silicone blocks are skin-friendly and more comfortable to use. In this embodiment, a liquid-retaining sponge structure is adopted.

[0072] Furthermore, the adsorption sleeve 31b is fitted over the outside of the core 31a. Specifically, a sealing ring 7 can be set between the adsorption sleeve 31b and the core 31a. Under the action of the sealing ring 7, an open negative pressure cavity 2 is formed, and the liquid outlet 1002 is located inside the negative pressure cavity 2. In this way, the skin in the area can be adsorbed while the liquid is being dispensed, so as to achieve a precise liquid dispensing effect.

[0073] Understandably, to achieve appropriate suction power, the air pressure in the negative pressure zone is best controlled within the range of -20 kPa to -40 kPa. Specific values ​​can be chosen such as -20 kPa, -30 kPa, or -40 kPa, and the air pressure in the negative pressure zone can be set based on skin feel and specific suction needs. For users with sensitive skin, an air pressure of -20 kPa can be used for suction, providing a gentler suction force that is less likely to leave marks on the skin, thus avoiding redness and itching. At -30 kPa, the suction power is moderate and suitable for most users' skin types. At -40 kPa, a stronger suction force is provided, suitable for users who can tolerate strong suction and are prone to positional shifts during use, such as users with oily skin. Therefore, controlling the air pressure within the range of -20 kPa to -40 kPa provides a good user experience. The specific air pressure value can be adjusted according to the actual design and is not specifically limited here.

[0074] Furthermore, to further improve the overall skin feel during the negative pressure adsorption process, the thickness of the adsorption sleeve 31b can be set between 0.8-2.8mm, such as 0.8mm, 1.4mm or 2.8mm. Chamfers can also be set on the edges of the adsorption sleeve 31b, with the chamfer range between 0.3mm and 0.8mm, such as 0.3mm, 0.5mm or 0.8mm.

[0075] Optionally, the thickness of the suction sleeve 31b can be set according to skin type needs. For example, users with sensitive skin are suitable for a thicker 2.8mm sleeve, which reduces pressure on the skin during suction, making it less prone to redness and itching. A 1.4mm thick suction sleeve 31b is suitable for most neutral skin types and most users. When the suction sleeve 31b is set to 0.8mm, it generates greater pressure on the skin during suction, resulting in a more stable attachment and making it suitable for oily skin users, preventing slippage during suction.

[0076] Optionally, the chamfer setting can also be adjusted according to the thickness of the adsorption sleeve 31b. The preferred chamfer structure is a single-sided chamfer structure, which can be an arc chamfer structure. Under the limitation of thickness, the chamfer should be made as large as possible, and only a part of the flat surface needs to be retained. For example, when the thickness of the adsorption sleeve 31b is set to 0.8mm, the chamfer size is 0.3mm; when the thickness of the adsorption sleeve 31b is 1.4mm, the chamfer size is 0.5mm; and when the thickness of the adsorption sleeve 31b is 2.8mm, the chamfer size is 0.8mm.

[0077] The above values ​​are not subject to specific combination limitations. By adopting the above thickness and chamfer range in the adsorption sleeve 31b, a curved contact surface can be formed, making it less likely to leave marks during adsorption and improving the skin feel.

[0078] Furthermore, the core 31a also includes an application unit 3121 and an elastic element 314. The application unit 3121 has a shell-like structure. One side of the core seat 311 is connected to the main body 32, and the application unit 3121 is movably sleeved on the other side of the core seat 311. At this time, the application unit 3121 is located on the side of the core 31aa closest to the skin, that is, the outermost side, and the liquid outlet 1002 is disposed through the application unit 3121. At this time, the adsorption element 3123 can be disposed between the core seat 311 and the application unit 3121. Since the adsorption element 3123 is elastic, the application unit 3121 and the core seat 311 can deliver the essence to the skin by squeezing the adsorption element 3123. With this setting, the liquid output can be controlled by changing the pressure during use, making it more flexible and convenient to use.

[0079] The elastic element 314 is preferably a spring. The elastic element 314 is located between the core seat 311 and the application unit 3121. Specifically, both ends of the elastic element 314 can be fixedly connected to the core seat 311 and the application unit 3121 respectively. In this case, the elastic element 314 can provide elastic buffer for the core seat 311 and the application unit 3121, thereby enabling the structure to rebound and reset more quickly, and improving the ease of use.

[0080] Furthermore, a microneedle chip 3122 is also installed on the application unit 3121. The microneedle chip 3122 has a nano-microneedle structure. At this time, the microneedle structure can promote the absorption of the essence by piercing the skin, thereby optimizing and improving the beauty effect.

[0081] Meanwhile, it is understandable that when the adsorption sleeve 31b is fitted onto the core 31a, the condition that the core 31a is located inside the adsorption sleeve 31b can be roughly divided into three positional states: the first positional state is that the core 31a does not exceed the opening of the adsorption sleeve 31b; the second positional state is that the end face of the core 31a is flush with the opening; and the third positional state is that the core 31a slightly exceeds the opening. Under the above three positional relationships, the adsorption sleeve 31b can be more stably adsorbed onto the skin. However, if the core 31a exceeds the opening of the adsorption sleeve 31b by too much, the skin's softness is limited, and it cannot cover the adsorption sleeve 31b well, resulting in a weak adsorption. Therefore, to ensure good adsorption strength, the core 31a and the adsorption sleeve 31b adopt the above three settings.

[0082] Preferably, in this embodiment, the first position setting is adopted, and the distance between the microneedle chip 3122 and the opening of the suction sleeve 31b is controlled between 0.5mm and 1.5mm, specifically 0.5mm, 1mm, or 1.5mm. The distance between the microneedle chip 3122 and the opening of the suction sleeve 31b should be set according to the user's level of stimulation. It can be seen that the larger the distance between the openings, the greater the movement stroke of the microneedle. The longer the stroke, the greater the compression of the elastic element 314, and thus the greater the force exerted on the skin. Therefore, on the one hand, different pain sensations will occur, and on the other hand, it may cause redness and swelling in sensitive skin.

[0083] Based on this, setting the distance between the microneedle chip 3122 and the opening of the suction sleeve 31b to 0.5mm reduces the stimulation intensity, thus meeting the needs of users with low pain tolerance and sensitive skin. Furthermore, setting the distance between the microneedle chip 3122 and the opening of the suction sleeve 31b to 1mm provides moderate stimulation, suitable for most users. Additionally, setting the distance between the microneedle chip 3122 and the opening of the suction sleeve 31b to 1.5mm allows for targeted application to users with thicker stratum corneum, enabling deeper penetration of the serum and optimizing the cosmetic effect.

[0084] With the distance set above, the distance can be adjusted according to different needs so that the skin can just contact the microneedle chip 3122 after negative pressure adsorption. Combined with the vibration effect of the vibration mechanism 9, it can reduce the pain and discomfort caused by excessive puncture force when the skin is pierced. The massage force is moderate and the skin feel is optimized. The specific distance value in actual setting is not limited here.

[0085] Looking back Figure 1Optionally, the skincare functions of the beauty device can be adjusted according to the skincare needs of different users. Based on this, the beauty device also includes a care component 12, which includes a light source care module, an electrode care module, and a heating care module.

[0086] For example, the light source care module uses an LED light-emitting light module to achieve intense pulsed light skin care by emitting light with a spectrum range of -nm. After the light acts on the skin, the photochemical effect will promote the rearrangement and regeneration of molecular structure within the collagen and elastin fibers in the dermis, making the skin firm and smooth. At the same time, the photothermal effect it produces can enhance vascular function, improve circulation, and promote collagen regeneration, thereby achieving the effect of eliminating wrinkles and shrinking pores.

[0087] Furthermore, the electrode care module mainly includes electrode heads for generating microcurrents. By applying microcurrents to the skin surface, it can stimulate the rapid proliferation of subcutaneous collagen, improve the symptoms of skin wrinkles, and gradually make the skin smooth and firm.

[0088] In addition, the heating care module mainly includes an electric heating pad structure. The electric heating pad generates heat, which is conducted to the skin when the beauty device is close to the skin, causing the pores to open slightly so that the essence can be better absorbed, thereby optimizing the care effect.

[0089] Here, the aforementioned care modules can be installed on the beauty device according to actual needs, and at least one of the light source care module, electrode care module, and heating care module is set on the beauty device. The specific selection of each care module is not specifically limited in practical application. It is understood that the care component 12 can be individually configured on the beauty device body 1 or the beauty head 31. The specific setting method can be adjusted according to the actual situation, and there are roughly two situations as follows:

[0090] Firstly, when a single care module needs to be installed, for example, when an electrode care module needs to be set on the beauty device, the electrode care module can be installed on the end of the beauty device body 1 near the beauty head 31, or the electrode care module can be directly installed on the beauty head 31.

[0091] Secondly, when multiple care modules need to be installed, for example, when the beauty device needs to be equipped with an electrode care module and a heating care module, the electrode care module can be installed on the beauty device body 1 and the heating care module can be installed on the beauty head 31, or both can be installed on the beauty device body 1, or both can be installed on the beauty head 31. It is understood that the embodiments of this application do not limit the specific number or specific location of each care module. Different types of care modules and different installation locations can be arbitrarily combined. Regardless of the number of care modules selected or the specific installation location selected, the final and actual specific combination method should be included in the protection scope of this application, and no specific restrictions are made here.

[0092] In summary, the beauty device provided in this embodiment has the following advantages:

[0093] ① By setting a negative pressure mechanism 5 and a negative pressure cavity 2 on the beauty head 31, a negative pressure area for adsorbing the skin can be formed, thereby adsorbing and positioning the skin. Under this condition, the beauty device is less likely to deviate. Subsequently, under the action of the air supply unit 14 and the adsorption element 3123, the essence can be accurately applied to the adsorbed skin, thus solving the problem of inaccurate essence application.

[0094] ② Combining the vibration mechanism 9 and the microneedle chip 3122, the vibration structure enables more accurate application of the serum, while the microneedle chip 3122 promotes the absorption of the serum, thus optimizing and enhancing the beauty effect.

[0095] ③ Based on the actual needs of different users, different care components 12 can be set to achieve different skin care effects. The structure is flexible and versatile, and the product has wide applicability.

[0096] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
