Technical Field

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

[0002] As a beauty device, the core technology of the hyaluronic acid beauty device lies in its precise delivery of beauty ingredients such as hyaluronic acid, vitamins, and collagen to the deep layers of the skin through microneedling or high-pressure jetting. The device works by using microneedles to penetrate the skin barrier, allowing nutrients to directly act on the dermis, thereby achieving deep hydration, anti-aging repair, and skin brightening effects, significantly improving skin hydration and enhancing radiance.

[0003] In related technologies, the beauty head of the beauty device has a liquid outlet channel inside, which is connected to a liquid outlet. Simultaneously, the end of the beauty head is equipped with a liquid outlet hole, which is connected to the liquid outlet, allowing the essence flowing from the liquid outlet to flow out through the liquid outlet hole and be applied to the surface of the skin.

[0004] In actual use, it is difficult to control the amount and speed of liquid output from the outlet of a beauty device. In order to deal with the problem of smooth liquid output caused by various factors, the amount and speed of liquid output are often increased. This not only wastes beauty ingredients, but also affects the accuracy of the device and the skin care effect due to local redundancy of ingredients. Utility Model Content

[0042] This utility model embodiment proposes a beauty component 100 for a beauty device, referring to... Figures 1 to 5 The beauty components 100 of the beauty device include:

[0043] The beauty head 110 has a liquid outlet channel 110C inside, a liquid outlet 1101 at one end of the liquid outlet channel 110C, and a liquid outlet hole 1102 at the end of the beauty head 110 that acts on the skin. The liquid outlet hole 1102 and the liquid outlet 1101 are spaced apart and connected along the axial direction of the beauty head 110.

[0044] A flow restrictor 120 is disposed inside the beauty head 110 and covers the liquid outlet 1101. The flow restrictor 120 has a microporous structure for liquid to pass through.

[0045] The beauty component 100 involved in this embodiment is applied to a beauty device. That is, the beauty component 100 is a component of the beauty device structure. It can be integrated into the beauty device body 300 (non-removable and replaceable), or it can be detachably connected to the beauty device body 300 (removable and replaceable) for repair or replacement. The beauty device involved can be a water-light beauty device, including but not limited to this.

[0046] The beauty component 100 includes a beauty head 110 and a flow restrictor 120. The beauty head 110 may be cylindrical, with an axially arranged liquid outlet channel 110C inside. One end of the liquid outlet channel 110C has a liquid outlet 1101, and the other end is used to connect to the liquid storage device of the beauty device. One end of the beauty head 110 is used to contact the skin and has a liquid outlet hole 1102. The liquid outlet 1101 and the liquid outlet hole 1102 are spaced apart along the axial direction of the beauty head 110, forming a spatially connected flow channel structure. The liquid outlet hole 1102 and the liquid outlet 1101 maintain a preset axial distance, so that the liquid flowing from the liquid outlet 1101 must flow through a channel or space before exiting from the liquid outlet hole 1102.

[0047] like Figure 4 and Figure 5 As shown, the flow restrictor 120 can be a sheet-like component covering the liquid outlet 1101, with dimensions not smaller than the liquid outlet 1101. It is fixed inside the beauty head 110 by interference fit, bonding, or snap-fit ​​to ensure complete obstruction of the liquid outlet 1101. The flow restrictor 120 is made of a stable material, with a uniformly distributed microporous structure on its surface facing the liquid outlet 1101. For example, the micropore diameter ranges from 50μm to 200μm, and the pore density is 100-500 pores / cm², forming a physical flow-restricting barrier for the liquid flow. The pore diameter and distribution density of the micropores can be adaptively designed according to the viscosity of the beauty liquid and the target flow rate. For example, high-viscosity liquids are matched with large-diameter or high-density micropores, and low-viscosity liquids are matched with small-diameter or low-density micropores to achieve differentiated flow-restricting effects. Specifically, the microporous structure of the flow restrictor 120 mechanically constrains the flow rate of the liquid outlet 1101. Its core principle is based on the aperture throttling effect of fluid mechanics: when the liquid flows out of the liquid outlet 1101, it needs to pass through the micropore group of the flow restrictor 120. The small aperture and dense distribution of the micropores form fluid resistance, so that the volume of liquid passing through per unit time is limited to a stable range.

[0048] When the beauty device is working, the liquid in the reservoir is driven to flow through the outlet channel 110C. The liquid first reaches the outlet 1101, where it is blocked by the flow-limiting element 120 and can only flow out through the microporous structure. As the liquid flows through the micropores, frictional resistance is generated due to the pore size limitation, and the flow rate changes from the initial high-pressure driven state to a stable low speed, forming a uniform laminar flow state. The liquid after flow restriction then flows to the outlet hole 1102, where it is discharged at a stable flow rate and evenly coated on the skin surface. This avoids the problem of liquid redundancy caused by a large amount of liquid coming out of the outlet 1312, significantly improving the precision of the beauty ingredients acting on the skin, thereby ensuring the skin care effect.

[0049] In some embodiments, refer to Figure 1 , Figure 4 and Figure 5 Beauty head 110 includes:

[0050] The core 111 has a liquid outlet channel 110C and a liquid outlet 1101 located on the end face of one end of the core 111.

[0051] An application unit 112 is provided with a liquid outlet hole 1102. The application unit 112 is sleeved on the outside of the core 111 and forms a liquid passage space 110J between the application unit 112 and the end face of one end of the core 111. The liquid outlet 1101 is connected to the liquid outlet hole 1102 through the liquid passage space 110J.

[0052] The flow restrictor 120 is housed in the liquid passage space 110J to cover the liquid outlet 1101.

[0053] In this embodiment, the beauty head 110 adopts a split design of core 111 and application unit 112. The flow-limiting component 120 is constructed through the liquid passage space 110J, forming a three-stage liquid transmission structure of "core guiding - liquid passage buffer - application unit output". Specifically, the core 111 is a columnar component with an axially extending liquid outlet channel 110C. The liquid outlet 1101 is located on the end face of one end of the core 111 and is coaxial with the liquid outlet channel 110C. The diameter range of the liquid outlet 1101 can be set according to actual needs, such as 1mm-3mm. This embodiment does not limit this.

[0054] The application unit 112 is a hollow sleeve-shaped component, fitted onto the outside of the core 111 near the liquid outlet 1101. A gap, such as 0.5mm-2mm, is reserved between its inner wall and the end face of the core 111, forming a square liquid passage space 110J. A liquid outlet hole 1102 is provided through the distal end face (skin contact end) of the application unit 112. The number of holes can be single or multiple; multiple holes can be arranged in an array or around the perimeter. The application unit 112 can be made of flexible silicone or elastic plastic. Its inner wall is sealed to the outside of the core 111 by a sealing ring or interference fit, ensuring that liquid can only be discharged through the liquid passage space 110J from the liquid outlet hole 1102. The flow restrictor 120 can be a circular thin sheet with an outer diameter smaller than the inner wall diameter of the application unit 112. The flow restrictor 120 is fixed to the end face of the core 111 by a positioning protrusion ring, a slot or other means, completely covering the liquid outlet 1101 and located inside the liquid passage space 110J.

[0055] When the liquid output from the core 111 through the liquid outlet 1101 enters the liquid passage space 110J, it must first pass through the micro-hole of the flow restrictor 120, and then be discharged through the liquid outlet 1102 of the application unit 112, forming a flow path of "liquid outlet 1101 → micro-hole of flow restrictor 120 → liquid passage space 110J → liquid outlet 1102".

[0056] In some embodiments, the flow restrictor 120 is a waterproof and breathable membrane; or,

[0057] The flow restrictor 120 is a breathable steel sheet; or,

[0058] The flow restrictor 120 is one of sponge and cotton pad.

[0059] In this embodiment, the flow restrictor 120 can be selected from various types such as a waterproof and breathable membrane, a breathable steel sheet, sponge, or cotton pad, depending on the application scenario. The waterproof and breathable membrane is made of polytetrafluoroethylene (PTFE) or ethylene-tetrafluoroethylene copolymer (ETFE), with a thickness of 50μm-100μm and uniformly distributed nanoscale micropores on its surface. An annular adhesive layer is provided at the edge of the membrane, completely adhering to the end face of the core 111, ensuring that the liquid outlet 1101 is fully covered by the membrane, and that the annular gap between the membrane and the liquid passage space 110J is coaxial. The micropore density is 100-120 pores / cm². 2 By controlling the membrane thickness and micropore parameters, the flow rate of liquids with different viscosities can be precisely adjusted.

[0060] The ventilated steel sheet can be made of stainless steel with a thickness of 0.3mm-0.8mm. The surface is formed with micron-level through holes by laser etching or electrical discharge machining. The edge of the steel sheet is provided with a positioning boss, which engages and is fixed with the groove on the end face of the core 111 to ensure that the steel sheet is completely aligned with the liquid outlet 1101.

[0061] The sponge-type flow restrictor 120 is made of medical-grade polyurethane sponge or hydrophilic polyester sponge, with a thickness of 1mm-3mm. Its edges are thermoformed and bonded to the end face of the core 111. The cotton-sheet-type flow restrictor 120 is made of degreased cotton or non-woven fabric, laminated and pressed to form a porous structure with a porosity of 60%-80% and a thickness of 0.5mm-2mm. Both materials completely cover the liquid outlet 1101, utilizing the natural pores within the material to achieve flow restriction. The pore diameter distribution ranges from 50μm to 500μm, and the liquid permeability can be controlled by adjusting the material density or the number of layers.

[0062] In some embodiments, the flow restrictor 120 is attached to the core 111. In this embodiment, the flow restrictor 120 can be bonded to the core 111 with adhesive tape or the like, thus attaching to the core 111. This simplifies assembly and disassembly, facilitating maintenance or replacement. In other words, the flow restrictor 120 is directly bonded to the end face of the core 111 through attachment, forming an integrated flow restrictor structure, which helps optimize the flow channel sealing and ease of installation.

[0063] In some embodiments, refer to Figure 6 The liquid outlet 1102 includes multiple first liquid outlet holes 11021, which are arranged around the central axis Z of the application unit 112. In this embodiment, the liquid outlet 1102 of the application unit 112 adopts a surrounding layout of multiple first liquid outlet holes 11021, and the uniform distribution and directional output of the beauty liquid are achieved through geometric symmetry design. Specifically, the application unit 112 is a hollow sleeve, and multiple first liquid outlet holes 11021 are opened on its end face facing the skin. Each hole is arranged in a ring array with the central axis Z of the application unit 112 as the center. The number of first liquid outlet holes 11021 can be 2-8, and they are spaced at equal angles along the circumference. After the liquid flows out from the liquid outlet channel 110C of the core 111 through the liquid outlet 1101, it first enters the liquid passage space 110J through the micropores of the flow restrictor 120, where it is buffered and flows radially diffused. Because the multiple first liquid outlet holes 11021 are symmetrically distributed, the pressure gradient of the liquid in the liquid passage space 110J is uniformized, and finally the liquid is discharged synchronously from each first liquid outlet hole 11021 at the same flow rate, forming a radial liquid outlet trajectory around the central axis Z.

[0064] In some embodiments, refer to Figures 4 to 6 The end face of the application unit 112 away from the core 111 is provided with a receiving cavity 112Q, and a plurality of first liquid outlet holes 11021 are located outside the receiving cavity 112Q;

[0065] Beauty Head 110 also includes:

[0066] The microneedle chip 113 is disposed in the accommodating cavity 112Q.

[0067] In this embodiment, the end face of the application unit 112 away from the core 111 is recessed to form a receiving cavity 112Q, with a depth of 1mm-3mm and a diameter or width of 8mm-15mm (adapted to common microneedle wafer 113 sizes). Multiple first liquid outlet holes 11021 are evenly distributed around the periphery of the receiving cavity 112Q, with the channel axis perpendicular to the skin surface. The microneedle wafer 113 is a square thin sheet with a thickness of 0.1mm-0.5mm, and its surface is arrayed with microneedles of 40μm-100μm length. The microneedle wafer 113 is fixed within the receiving cavity 112Q by snap-fitting, bonding, or other means.

[0068] The liquid flowing out of the liquid outlet 1101 can be directly discharged through the first liquid outlet 11021, forming a uniform liquid film on the skin surface corresponding to the periphery of the receiving cavity 112Q, so as to spread on the skin surface. Meanwhile, the microneedle chip 113 pierces the stratum corneum of the skin, allowing the liquid to enter the skin, so that the nutrients can directly act on the epidermis and then penetrate into the dermis, thereby achieving the effects of deep hydration, anti-aging repair, and brightening skin tone.

[0069] In some embodiments, refer to Figure 5 and Figure 6 The liquid outlet 1102 also includes a second liquid outlet 11022, which is located within the accommodating cavity 112Q. The microneedle wafer 113 has a liquid passage 1131, which is positioned opposite to the second liquid outlet 11022. In this embodiment, the liquid outlet 1102 of the application unit 112 adopts a central hole layout of the second liquid outlet 11022. The second liquid outlet 11022 is distributed on the bottom surface of the accommodating cavity 112Q, directly connecting to the central region of the liquid passage 110J. Its flow channel length is shorter than the surrounding first liquid outlet 11021, forming a central guiding channel reaching the skin surface. That is, this embodiment constructs a composite liquid delivery system with central penetration and peripheral spreading by adding a second liquid outlet 11022 to the surrounding first liquid outlet 11021. The number of second liquid outlets 11022 can be one or more, and this embodiment does not limit this.

[0070] The central region of the microneedle chip 113 has a liquid passage hole 1131 corresponding to the position of the first liquid outlet hole 11021, and the number and position of the holes correspond to the second liquid outlet hole 11022. The liquid flowing out of the liquid outlet 1101 can also enter the receiving cavity 112Q through the second liquid outlet hole 11022, and reach the side of the microneedle chip 113 facing the skin through the liquid passage hole 1131, and penetrate into the skin with the microneedle puncture action.

[0071] In some embodiments, refer to Figure 1 , Figures 4 to 6 The beauty head 110 also includes:

[0072] An adsorption sleeve 114 covers the application unit 112 and the core 111 and forms an air passage space 110G between the adsorption sleeve 114 and the application unit 112 and the core 111.

[0073] The end face of the application unit 112 away from the core 111 is also provided with a plurality of air passages 112D. The plurality of air passages 112D are distributed on the periphery of the accommodating cavity 112Q. Each second liquid outlet hole 11022 is located in an air passage 112D. One end of the air passage 112D communicates with the accommodating cavity 112Q, and the other end passes through the side of the application unit 112 to communicate with the air passage space 110G.

[0074] The core 111 is also provided with an air intake channel 110X. One end of the air intake channel 110X is connected to the air passage space 110G, and the other end is used to connect to the negative pressure mechanism.

[0075] When the negative pressure mechanism is working, air is drawn from the air passage 110G through the suction channel 110X. According to the designed gas flow path, air in the accommodating cavity 112Q enters the air passage 110G through each air passage 112D to create a negative pressure environment. Under this negative pressure, the liquid in the container 200 flows into the liquid outlet channel 110C through the outlet 1312 of the needle 131, and then is transported along the liquid outlet channel 110C to the liquid outlet 1101. It is then discharged into the accommodating cavity 112Q through the second liquid outlet and into the corresponding air passage 112D through the first liquid outlet, and subsequently applied to the skin. Simultaneously, the air inlet 1311 is connected to the atmosphere to introduce air into the container 200, ensuring a stable gas balance within the container 200 and achieving normal liquid delivery.

[0076] In some embodiments, refer to Figures 1 to 3 The beauty components 100 of the beauty device also include:

[0077] The main body 130 has a beauty head 110 located at one end. A positioning recess 130Q for accommodating an external container 200 is provided on one side wall of the main body 130. A pin 131 is provided in the positioning recess 130Q. An air inlet 1311 and an outlet 1312 are provided on the surface of the pin 131. The outlet 1312 is connected to the other end of the liquid outlet channel 110C.

[0078] In this embodiment, the main body 130 may be elongated, but is not limited to this shape. Depending on the structural design, when the beauty component 100 is detachable in the beauty device, the main body 130 may be a component existing independently of the beauty device body 300; when the beauty component 100 is non-detachable in the beauty device, a component in the beauty device body 300 may be used as the main body 130, such as the shell of the beauty device. A positioning recess 130Q is provided on one side wall of the main body 130. This positioning recess 130Q may be formed by a partial recess in one side wall of the main body 130, and its inner wall shape matches the outer wall shape of the outer container 200, such as the cylindrical mouth of a vial. The positioning recess 130Q may be a cylindrical groove. The positioning recess 130Q is used to accommodate the outer container 200, which is inserted into the positioning recess 130Q through its mouth end to achieve positioning and installation on the main body 130. The outer container 200 can be a common serum container 200 such as a vial, including but not limited to this.

[0079] A pin 131 is disposed in a positioning recess 130Q, specifically on the bottom surface of the positioning recess 130Q. The surface of the pin 131 is provided with an air inlet 1311 and an outlet 1312. The outlet 1312 communicates with the other end of the liquid outlet channel 110C, allowing liquid in the external container 200 to enter the liquid outlet channel 110C through the outlet 1312 and be transported to the liquid outlet 1101. For example... Figure 3 As shown, the liquid outlet channel 110C inside the core 111 may include an integrated pipe structure 110C1 designed as an integral part of the core 111, or an independent pipe structure 110C2 (such as a hose) assembled inside the core 111, or both of the above. This embodiment does not limit this. Taking the example that the liquid outlet channel 110C inside the core 111 is composed of an integrated pipe structure 110C1 designed as an integral part of the core 111 and an independent pipe structure 110C2 (such as a hose) assembled inside the core 111, one end of the integrated pipe structure 110C1 is provided with a liquid outlet 1101, and the other end of the integrated pipe structure 110C1 is connected to the inner wall of the main body 130 through the independent pipe structure 110C2 (such as a hose) and communicates with the outlet 1312 of the pin 131.

[0080] The air inlet 1311 is used for air intake. Gas enters the container 200 through the air inlet 1311 and acts on the liquid, causing the liquid to flow out through the outlet 1312. The air pressure control system of the beauty device can be a negative pressure system or a positive pressure system. When a negative pressure system is used, the negative pressure system is connected to the liquid outlet channel 110C, while the air inlet 1311 is connected to the atmosphere. By drawing negative pressure, the liquid in the container 200 is drawn out through the outlet 1312. When a positive pressure system is used, the positive pressure system is connected to the air inlet 1311. By applying positive pressure, the liquid in the container 200 is squeezed out through the outlet 1312. Both air pressure systems mentioned above are compatible with the beauty component 100 of this embodiment, and this embodiment does not impose any limitations on them.

[0081] In some embodiments, refer to Figure 4 and Figure 5 In the axial direction of the beauty head 110, the liquid outlet 1101 and the liquid outlet 1102 are not collinear. That is, while the liquid outlet 1101 and the liquid outlet are distributed at intervals along the axial direction of the beauty head 110, their projections on the plane perpendicular to the axis Z are misaligned. This design, in conjunction with the microporous structure of the flow restrictor 120, creates a more complex liquid flow path. From a fluid dynamics perspective, the non-collinear arrangement breaks the inertia of the straight-line flow of liquid within the flow channel. When the liquid flows out through the microporous structure of the flow restrictor 120, because the liquid outlet 1102 and the liquid outlet 1101 are not collinear, the liquid needs to change its flow direction to be discharged from the liquid outlet 1102. During this process, the liquid has more contact and friction with the flow channel wall, further enhancing the restriction effect on the liquid velocity and flow rate, making the liquid flow state more stable. At the same time, the meandering flow channel formed by the non-collinear layout effectively disperses the pressure fluctuations when the liquid flows out, avoiding the jetting or intermittent liquid discharge caused by uneven pressure. In addition, the non-collinear liquid outlet 1102 and liquid outlet 1101 are designed to promote more thorough mixing and diffusion of the beauty essence in the flow channel, making the beauty essence components discharged from the liquid outlet 1102 more evenly distributed, and greatly improving the evenness and precision of the beauty ingredients acting on the skin.
