Description

Technical Field

[0001] This utility model relates to the technical field of beauty instruments, and in particular to a water-light gel and a beauty instrument. Background Technology

[0002] With the improvement of living standards and the upgrading of skin care concepts, consumers' demand for efficient and safe skin beauty is increasing. Therefore, the water-light beauty device perfectly meets consumers' skin care needs. The water-light beauty device is a beauty device product that uses high-pressure jet to evenly apply beauty essence to the skin and combines it with other auxiliary skin care methods to achieve excellent skin penetration and skin care effects, and is widely favored by consumers.

[0003] Currently, conventional beauty devices typically use mechanical dispensing mechanisms to atomize and dispense beauty serums, such as a lead screw structure. However, these mechanical dispensing mechanisms have inherent push-pull stroke requirements, thus necessitating space constraints. This results in generally large mechanical dispensing structures that cannot be installed in confined spaces, limiting their design options. While scaling down the mechanical structure proportionally could solve the compactness issue, it would reduce the dispensing force, affecting the atomization effect and potentially increasing installation costs. Therefore, a solution that can adapt to confined spaces while still achieving precise atomization remains lacking, requiring improvement.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] The following is in conjunction with the appendix Figure 1-18 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0091] Please refer to Figure 1 as well as Figure 2 This utility model provides a water-light bullet, including a liquid bullet body 1, an atomizing head 2, and an airflow channel 3.

[0092] Hyaluronic acid serums are typically used with beauty devices. When in use, the serum flows towards the atomizing head 2, is atomized, and then exits through the atomizing head 2. For ease of understanding, the direction in which the serum exits through the atomizing head 2 is defined as "front," and the opposite direction as "rear." Similarly, based on the direction in which the serum exits through the atomizing head 2, different components can have positional relationships such as front, rear, front side, rear side, front part, rear, front end, or rear end.

[0093] Based on this, the liquid bullet body 1 has a liquid storage cavity 4. An atomizing head 2 is disposed on the liquid bullet body 1, and the atomizing head 2 has an atomizing port 201. The atomizing port 201 is connected to the liquid storage cavity 4 and is located at the front end of the liquid storage cavity 4 along the liquid outlet direction. An airflow channel 3 is connected to both the atomizing port 201 and the liquid storage cavity 4, and is used to connect to an air source (not shown in the figure). The airflow channel 3 is used to distribute airflow to the atomizing head 2 and the liquid storage cavity 4 respectively. Part of the airflow flows into the liquid storage cavity 4, driving the beauty liquid to flow into the atomizing head 2, while another part of the airflow flows into the atomizing head 2, causing the airflow to collide with the beauty liquid flowing into the atomizing head 2, atomizing the beauty liquid and causing it to flow out from the atomizing port 201.

[0094] Reference Figure 1-2 In some embodiments, the atomizing head 2 is located in front of the liquid storage chamber 4, and the atomizing port 201 is located at the front end of the atomizing head 2. The liquid storage chamber 4 is used to store the beauty essence. When the airflow enters the atomizing head 2, the atomizing head 2 accelerates the airflow, thereby forming a decompression zone at the front end of the liquid storage chamber 4 and drawing the beauty essence into the atomizing head 2. The beauty essence is then atomized by the collision of the airflow within the atomizing head 2.

[0095] At the same time, the airflow channel 3 is connected to the rear of the liquid storage chamber 4, allowing airflow to enter the rear of the liquid storage chamber 4 to push the beauty liquid in the liquid storage chamber 4, thereby increasing the liquid output pressure of the beauty liquid and making the liquid output more uniform and stable.

[0096] The water-light bullet provided by this utility model has an airflow channel 3 that connects the atomizing head 2 and the liquid storage chamber 4 respectively. During the atomization of the beauty essence, the airflow channel 3 is used to introduce airflow into the atomizing head 2 and the liquid storage chamber 4 respectively. This not only accelerates the atomization of the beauty essence with airflow, but also simultaneously increases the liquid output pressure, achieving a reasonable combination of liquid and gas output, which is conducive to achieving a fine atomization effect. In addition, the structural design of the water-light bullet provides the conditions for reusing the air source power of the atomized beauty essence to achieve liquid propulsion, eliminating the need for a mechanical liquid propulsion structure. This allows for a more flexible and ingenious structural arrangement of the beauty device used with it, meeting the requirements of structural compactness.

[0097] Reference Figure 2In some embodiments, a one-way vent valve device 15 can be installed at the connection between the liquid storage chamber 4 and the airflow channel 3 to reduce the risk of backflow of the liquid in the liquid storage chamber 4 into the airflow channel after the airflow supply is stopped. It is understood that the one-way vent valve device 15 can be selected according to actual design requirements, such as a spring-loaded one-way valve, a diaphragm one-way valve, a duckbill one-way valve, or a ball valve one-way valve. There is no limitation on the type of one-way vent valve device 15.

[0098] Reference Figure 3 In some embodiments, the water-light bullet also includes a piston 5. The piston 5 is movably disposed within the liquid storage chamber 4, and the airflow channel 3 passes into the liquid storage chamber 4, which pushes the piston 5 to squeeze the beauty liquid, thereby driving the beauty liquid to flow into the atomizing head 2.

[0099] In some embodiments, the shape of the piston 5 is consistent with the cross-sectional profile of the liquid storage cavity 4, and the periphery of the piston 5 is in sealed contact with the inner wall of the liquid storage cavity 4. For example, the sealed contact can be achieved by adding a sealing ring. The specific structure of the piston 5 and the sealing method are not limited here.

[0100] Based on the piston 5's design, when the reservoir 4 is filled with beauty essence, piston 5 is in its initial position, near the rear end of the liquid bullet body 1. At this time, the airflow entering from the rear of the reservoir 4 pushes piston 5 towards the front end of the reservoir 4, thus fully discharging the beauty essence to the atomizing head 2. This effectively prevents beauty essence residue from remaining in the reservoir 4, resulting in more thorough dispensing. Furthermore, the piston 5's sealing contact with the reservoir 4 wall effectively reduces turbulence within the reservoir 4, preventing airflow from entering the reservoir 4 and forming air bubbles that could affect the output of the beauty essence to the atomizing head 2. The sealing contact between piston 5 and the reservoir 4 wall also optimizes dispensing stability.

[0101] Continue to refer to Figure 3 In some embodiments, the atomizing head 2 has an interconnected air outlet channel 6 and a liquid outlet channel 7. The liquid outlet channel 7 is connected to the liquid storage chamber 4 and is used to guide the beauty liquid into the air outlet channel 6 for atomization.

[0102] Specifically, the liquid outlet channel 7 is located in front of the liquid storage chamber 4, and at least part of the air outlet channel 6 is located in front of the liquid outlet channel 7. The air outlet channel 6 is connected to the atomizing port 201. The air outlet channel 6 is used to receive external airflow and accelerate the airflow. At this time, a negative pressure area can be formed at the front end of the liquid storage chamber 4, thereby drawing the beauty liquid into the atomizing head 2. In the atomizing head 2, the beauty liquid is atomized by the collision and fragmentation of the airflow. The atomized beauty liquid, under the continuous push of the airflow, flows out from the atomizing port 201 located in front of the air outlet channel 6. During this process, the beauty liquid flows out in a straight line, the liquid outlet is smooth and not easily obstructed by the structure, which can effectively improve the stability of the liquid outlet and the atomization effect.

[0103] Optionally, there are several ways to configure the air outlet channel 6:

[0104] Reference Figure 4 In one embodiment, the air outlet channel 6 includes a first annular constriction section 61 and a straight section 62.

[0105] The first annular constriction section 61 is connected to the airflow channel 3, and the straight section 62 is connected to the first annular constriction section 61 and is located in front of the first annular constriction section 61 in the liquid outlet direction. The first annular constriction section 61 is arranged around the periphery of the liquid outlet channel 7, and the liquid outlet channel 7 extends into the straight section 62.

[0106] Specifically, the width of the first annular constriction section 61 gradually decreases along the liquid outlet direction. When the airflow enters the first annular constriction section 61, its speed gradually increases and it enters the straight section 62. Furthermore, the high-speed airflow reaches the straight section 62 and creates a negative pressure area near the outlet of the liquid outlet channel 7, thereby drawing the beauty essence into the straight section 62. At this time, the beauty essence is thoroughly cut by the airflow within the straight section 62, forming multiple fine atomized particles, achieving a fine atomization function.

[0107] More specifically, the liquid outlet channel 7 extends into the straight section 62, and the first annular constriction section 61 is arranged around the periphery of the liquid outlet channel 7. Therefore, the air outlet channel 6 forms an annular outlet 16 around the liquid outlet channel 7 at the outlet of the liquid outlet channel 7. The airflow can be evenly gathered near the outlet of the liquid outlet channel 7, and can produce uniform impact on the beauty liquid output from the liquid outlet channel 7 from all directions, so as to achieve uniform atomization.

[0108] Furthermore, due to the design of the straight section 62, the beauty essence is atomized within this section, preventing it from escaping outside the air outlet channel 6, resulting in more stable liquid output. The straight section 62 also increases the interaction space and time between the airflow and the atomized particles, allowing for more thorough contact and collision, leading to finer atomization. This solves the problems of unstable liquid output and insufficiently fine atomized particles. Similarly, the design of the outlet channel 7 extending into the straight section 62 allows for more precise machining of the annular outlet 16 of the annular air outlet channel. Only the inner diameter of the straight section 62 and the outer diameter of the outlet channel 7 need to be precisely machined, making it easier to control the airflow velocity and volume, and reducing manufacturing difficulty.

[0109] It is understood that in this application, the ring width is the difference between the outer radius and the inner radius of the cross-section of the first annular constriction segment 61. The cross-section of the first annular constriction segment 61 is the annular cross-section formed after cutting perpendicular to the axis of the first annular constriction segment 61. The width of the annular outlet 16 is the ring width of the annular outlet 16, and correspondingly, the width of the first annular constriction segment 61 is also the ring width of the first annular constriction segment 61. For ease of understanding, the ring width of the annular outlet 16 is defined as d1, and the ring width of the first annular constriction segment 61 is defined as d2.

[0110] In another embodiment, refer to Figure 5 The air outlet channel 6 includes a first annular constriction section 61, a straight section 62, and a first flared section 63. The first annular constriction section 61 is connected to the airflow channel 3. The straight section 62 is connected to the first annular constriction section 61 and is located in front of the first annular constriction section 61 in the liquid outlet direction. The first annular constriction section 61 is arranged around the periphery of the liquid outlet channel 7, and the liquid outlet channel 7 extends into the straight section 62. The first flared section 63 is located at the end of the straight section 62 away from the first annular constriction section 61 and is connected to the atomizing port 201.

[0111] Specifically, in this embodiment, the relative positions and effects of the first annular constriction section 61 and the straight section 62 are the same as in the previous embodiment, and will not be repeated here. The difference is that the diameter of the first flared section 63 gradually increases along the liquid outlet direction, and the minimum aperture of the first flared section 63 is consistent with the diameter of the straight section 62. At this time, the atomized beauty liquid can smoothly enter the first flared section 63 from the straight section 62. As the diameter of the first flared section 63 gradually increases, the airflow velocity gradually decreases, thus reducing the speed at which the atomized beauty liquid flows out, allowing it to be applied to the skin more gently. In addition, the first flared section 63 can expand the angle of the beauty liquid's flow and diffusion, thereby expanding the application area of ​​the beauty liquid, while preventing the beauty liquid from re-collecting into water droplets after flowing out of the atomizing head 2, thus optimizing and improving the application effect.

[0112] Alternatively, in another embodiment, refer to Figure 6 The air outlet channel 6 includes a second annular constriction section 64 and a second flaring section 65. The second annular constriction section 64 is connected to the airflow channel 3; the second flaring section 65 is connected to the second annular constriction section 64 and the atomizing port 201 respectively, and is located in front of the second annular constriction section 64 in the liquid outlet direction. The second annular constriction section 64 is arranged around the periphery of the liquid outlet channel 7.

[0113] Specifically, the width of the second annular constriction section 64 gradually decreases along the liquid outlet direction; in addition, the diameter of the second flaring section 65 gradually increases along the liquid outlet direction, and the minimum diameter of the second flaring section 65 is the same as the outer diameter at the minimum width of the second annular constriction section 64, and the narrowest points of the two are connected to each other.

[0114] Based on the above setup, the beauty liquid flows out from the outlet channel 7 and enters the second annular constriction section 64. The airflow collides with the front end of the second annular constriction section 64 to achieve atomization, and then the atomized beauty liquid flows out through the second expansion section 65.

[0115] In this embodiment, the airflow path in the second annular constriction section 64 is straight, without any inflection points affecting airflow velocity and wind pressure. This allows the airflow to collide more directly and fully with the beauty liquid, optimizing the atomization effect. Furthermore, because the airflow velocity decreases minimally, the beauty liquid atomizes and flows out faster and more completely. In addition, the beauty liquid overflows from the second flaring section 65 after atomization, also achieving a large-area application effect.

[0116] In some embodiments, refer to Figure 6 The second annular constriction section 64 forms a conical profile, thus creating an airway extension focus a, which is located within the second flaring section 65.

[0117] Based on the above settings, since the airway extension focus a is within the second flared section 65, the high-speed airflow can reach the second flared section 65. When the beauty liquid flows out from the liquid outlet channel 7 and enters the second annular constriction section 64, the airflow collides with the front end of the second annular constriction section 64 to achieve preliminary atomization. Furthermore, the beauty liquid particles after preliminary atomization can still come into further contact and collide with the high-speed airflow during the process of flowing into the rear end of the second flared section 65, achieving further atomization, thereby making the atomized particles smaller and achieving a fine atomization effect. After atomization, the beauty liquid overflows directly under the guidance of the second flared section 65, which can achieve a large-area application effect.

[0118] In this embodiment, the area where the airflow collides and contacts the beauty liquid can extend from the front end of the second annular constriction section 64 to the rear end of the second flaring section 65. That is, the atomization area is increased and the atomization path is lengthened, thereby forming multiple atomization processes, making the atomization more complete and the atomization effect better.

[0119] Therefore, by using a constriction acceleration method to increase the gas flow rate inside the atomizing head 2, a fine atomization effect is achieved under linear guidance and / or flaring dispersion guidance, and the liquid dispensing experience is significantly optimized and improved. In addition, it is understood that in other embodiments, the shape and setting angle in this solution can be simply replaced to achieve the same or better technical effect.

[0120] During liquid dispensing, excessively large volumes require higher atomization energy, increasing the demands on instrument hardware and raising costs. However, given a fixed atomization energy capacity of the instrument, excessive dispensing results in too much liquid needing to be dispersed, reducing the energy gained per unit volume and hindering proper atomization, thus impacting the atomization effect. Please refer to [reference needed]. Figure 6 In some embodiments, to avoid affecting the atomization effect, the atomizing head 2 includes a flow buffer 8, which is disposed in the liquid outlet channel 7 and has micropores for the passage of beauty liquid.

[0121] Based on the above settings, the slow-flow component 8 can effectively slow down the flow rate of the beauty liquid to prevent a large amount of beauty liquid from flowing out in a short period of time, thereby optimizing and improving the atomization effect.

[0122] In some embodiments, refer to Figure 6 The flow-slowing element 8 is a cotton layer, with pores forming micropores. Specifically, the cotton layer can be made of materials such as sponge or pearl cotton; the specific material of the cotton layer is not limited here. Furthermore, the cotton layer can be directly inserted into the liquid outlet channel 7 or placed at the inlet of the liquid outlet channel 7, thereby utilizing the micropores to slow down the liquid flow rate and achieve the effect of controlling the liquid output.

[0123] In other embodiments, reference is made to Figure 7 The flow-retarding element 8 is a mesh sheet with micropores running through it. Specifically, multiple micropores are evenly distributed on the mesh sheet. During installation, a snap-fit ​​groove (not shown) can be pre-set inside the liquid cartridge body 1. The mesh sheet is then easily snapped into the snap-fit ​​groove to achieve installation. At this time, the mesh sheet covers one end of the liquid outlet channel 7, and the micropores can reduce the amount of liquid flowing from the liquid storage chamber 4 into the liquid outlet channel 7, thus controlling the liquid output. It is understood that the mesh sheet can also be fixed to the inlet end of the liquid outlet channel 7 of the atomizing head 2 by adhesive bonding. Here, the installation method of the mesh sheet is not limited.

[0124] Optionally, when the flow buffer 8 is a mesh, the micropore size of the mesh is 4μm-7μm.

[0125] It is understandable that when the micropore size of the mesh is less than 4μm, the liquid output of the liquid outlet channel 7 may be too small. Firstly, it may be difficult for the liquid to form a stable "liquid film" or "liquid column" in the atomizing head 2. The interaction area between the high-speed airflow and the liquid is reduced and the contact time is shortened, resulting in the liquid not being fully broken up, leading to problems such as larger atomized particle diameter and uneven particle size distribution. Secondly, the total amount of generated droplets is reduced, and due to the weakened interaction between droplets (such as collision and aggregation), the diffusion power of the droplets is insufficient, which will lead to a smaller spatial range of the atomization area, making it difficult to uniformly cover the target area. Thirdly, the supply of liquid in the atomizing head 2 is unstable, and the atomization process will be intermittent, making it impossible to maintain a continuous and stable atomization state.

[0126] However, when the micropore size of the mesh is greater than 7μm, the liquid output of the liquid outlet channel 7 may still be too high.

[0127] First, the reduced airflow per unit volume of liquid makes it difficult for the liquid to break down into tiny droplets, instead leading to the formation of larger droplets. This results in significantly larger atomized particle diameters, and even the formation of un-atomized droplet clusters or liquid flows, losing the fineness that atomization should provide. Second, excessive liquid in the atomizing head 2 can easily form an overly thick liquid film or congested liquid flow, causing uneven energy distribution of the high-speed airflow. In some areas, the liquid is broken down into small droplets due to concentrated energy, while in others, large droplets remain due to insufficient energy. This results in a wide range of atomized particle size distribution (a mixture of coarse and fine particles). Large droplets will settle quickly due to gravity, forming localized liquid accumulation in the target area, while fine particles may be over-dispersed, resulting in waste. Third, the gravity and viscosity of excessive liquid will counteract the diffusion force of atomization, weakening the "penetrating power" of the atomized spray and reducing its effective range. At the same time, liquid flow congestion may cause airflow turbulence inside the atomizing head 2, making it easy for the spray direction to deviate and failing to accurately cover the target area.

[0128] Therefore, by setting the micropore size of the mesh to 4μm-7μm, the liquid discharge effect is relatively stable.

[0129] For example, the specific size of the micropores can be 4μm, 5μm, 6μm, or 7μm. The specific size of the micropores can be adjusted according to the relevant parameters of different beauty solutions (such as viscosity, surface tension, density, solute concentration, surfactant content, shear sensitivity, etc.), and no specific limitation is made here.

[0130] Continue to refer to Figure 7In some embodiments, the atomizing head 2 includes an inner needle 21 and an outer cylinder 22. The inner needle 21 is connected to the liquid bullet body 1, and a liquid outlet channel 7 is disposed on the inner needle 21. The outer cylinder 22 has an assembly hole 211, one end of the inner needle 21 is located inside the flow channel hole 31, and the outer cylinder 22 is fitted with the outer wall of the inner needle 21 through the inner wall of the assembly hole 211. An air outlet channel 6 is formed between the inner needle 21 and the outer cylinder 22.

[0131] In some specific embodiments, combined with Figure 7 , Figure 8 as well as Figure 9 The front end of the liquid bullet body 1 is provided with a mounting hole 1022, which is connected to the liquid storage cavity 4. The outer edge contour of the inner needle 21 is adapted to the opening contour of the mounting hole 1022. At this time, the inner needle 21 can be pressed into the mounting hole 1022. The inner needle 21 is fixedly installed by using the transition fit or interference fit between the mounting hole 1022 and the inner needle 21. The liquid outlet channel 7 passes through both ends of the inner needle 21, and the beauty liquid can flow from the liquid storage cavity 4 through the inner needle 21 and enter the air outlet channel 6.

[0132] In some specific embodiments, the outer walls of the flow channel hole 31 and the inner needle 21 are both circular contours, and the inner wall of the flow channel hole 31 and the outer wall of the inner needle 21 are press-fitted together by an interference fit or a transition fit, thereby achieving mutual fixation between the outer cylinder 22 and the inner needle 21. Furthermore, through the above-mentioned press-fitting connection method, the concentricity between the liquid outlet channel 7 and the gas outlet channel 6 can be effectively improved, and the flow of liquid and gas is smoother.

[0133] In some embodiments, the outer cylinder 22 is further provided with an air inlet 221 that is connected to the air outlet channel 6 and the airflow channel 3 respectively.

[0134] Specifically, the air inlet 221 is located near the rear end of the inner needle 21, which facilitates the flow of air from the rear side of the first annular constriction section 61 or the second annular constriction section 64 to the front side, allowing the airflow to obtain an appropriate acceleration stroke and thus gain sufficient speed when interacting with the liquid.

[0135] Based on the above configuration, by pressing the inner needle 21 and the outer cylinder 22 together, the liquid outlet channel 7 and the air outlet channel 6 can be formed, simplifying the overall number of components and making assembly easy. Furthermore, this effectively improves the concentricity of the liquid outlet channel 7 and the air outlet channel 6 (i.e., their axes are basically coincident). At this point, the high-speed airflow can symmetrically and uniformly envelop the liquid, forming a stable gas-liquid shear interface, thereby further improving the uniformity of atomized particles and enhancing atomization stability.

[0136] Optionally, the overlap between the inner needle 21 and the outer cylinder 22 is between 2mm and 5mm. It is understood that the overlap between the inner needle 21 and the outer cylinder 22 is the length of their contact. When the overlap between the inner needle 21 and the outer cylinder 22 is between 2mm and 5mm, the connection is relatively stable. For example, the overlap between the inner needle 21 and the outer cylinder 22 can be 2mm, 3mm, 4mm, or 5mm. No specific limit is placed on the exact overlap between the inner needle 21 and the outer cylinder 22.

[0137] Reference Figure 10 and Figure 11 In order to enable gas to be efficiently introduced into the atomizing head 2 and the liquid storage chamber 4, the airflow channel 3 can be configured in several ways:

[0138] In some of these embodiments, reference is made to Figure 10 An airflow channel 3 is formed inside the liquid bullet body 1. One end of the airflow channel 3 is connected to the atomizing head 2, and the other end is used to connect to the air source 9. The inner wall of the airflow channel 3 has a vent 32, which is connected to the rear end of the liquid storage cavity 4. The vent 32 is used to guide the airflow from the airflow channel 3 to the liquid storage cavity 4.

[0139] In some embodiments, specifically, a flow channel hole 31 is provided through the liquid bullet body 1 along its length. The flow channel hole 31 opens on both sides of the liquid bullet body 1 to form an airflow channel 3. The front end of the airflow channel 3 is connected to the atomizing head 2, and the rear end is connected to the air source 9. It can be understood that the air source 9 referred to here can be an air pump, which is connected to the liquid bullet body 1 through a pipe structure to achieve the liquid output effect.

[0140] Based on this, the vent 32 is located near the rear side of the liquid storage chamber 4. When the air source 9 introduces airflow into the airflow channel 3, some of the gas will flow into the liquid storage chamber 4 through the vent 32, changing the air pressure at the rear end of the liquid storage chamber 4, squeezing the beauty liquid or squeezing the piston 5, and achieving the effect of pushing out the liquid.

[0141] In some embodiments, the airflow channel 3 is integrated on the liquid bullet body 1, making the water-light bullet structure simpler and more compact.

[0142] Alternatively, in other embodiments, refer to Figure 11 The airflow channel 3 includes a first pipe 33 and a second pipe 34. One end of the first pipe 33 is connected to the atomizing head 2, and the other end is used to connect to the air source 9. One end of the second pipe 34 is used to connect to the air source 9, and the other end is connected to the liquid bullet body 1 and communicates with the liquid storage chamber 4.

[0143] Specifically, in some embodiments, both the first pipe 33 and the second pipe 34 are flexible tubes. The connection between the first pipe 33 and the second pipe 34 can be a direct connection or an indirect connection through other components. For example, since the atomizing head 2 is located inside the liquid bullet body 1, a front chamber 105 needs to be additionally provided inside the liquid bullet body 1, and a connector communicating with the front chamber 105 needs to be provided on the liquid bullet body 1. By connecting the first pipe 33 to the connector of the liquid bullet body 1, the first pipe 33 can be indirectly connected to the atomizing head 2 through the chamber.

[0144] Meanwhile, the second pipe 34 only needs to be directly connected to the liquid storage cavity 4 on the liquid bullet body 1. Specifically, by setting a connector on the rear side of the liquid bullet body 1 that connects to the liquid storage cavity 4, the second pipe 34 can be connected to the liquid storage cavity 4 by connecting the second pipe 34 to the connector. Therefore, whether the first pipe 33 and the second pipe 34 are connected directly or indirectly, they should be included in the scope of this application. No restrictions are placed on the specific connection method of the first pipe 33 and the second pipe 34.

[0145] In some embodiments, the air source 9 is an air pump. One or two air sources 9 can be configured. When one air source 9 is configured, a three-way connector can be added to simultaneously connect the output of the air source 9 to both the first pipe 33 and the second pipe 34, achieving synchronous air output. Furthermore, the air source 9 can be reused, which helps optimize the instrument's structural space. When two air sources 9 are configured, they can be connected to the first pipe 33 and the second pipe 34 respectively, achieving the same synchronous air output. The power for atomization and liquid dispensing can be adjusted separately, catering to various needs. No specific configuration of the air source 9 is limited here.

[0146] The following embodiments refer to Figures 8-12 .

[0147] In some embodiments, when the airflow channel 3 is formed inside the liquid bullet body 1, the liquid bullet body 1 includes a shell 101 and a partition 102.

[0148] The housing 101 has openings at both ends. An airflow channel 3 is disposed on the housing 101. A partition 102 is disposed on the housing 101, dividing the interior of the housing 101 into a liquid storage chamber 4 and a front chamber 105. In addition, an atomizing head 2 is disposed on the partition 102 and located in the front chamber 105. The partition 102 has an air outlet 1021, and one end of the airflow channel 3 is connected to the front chamber 105 through the air outlet 1021.

[0149] Specifically, in some embodiments, the housing 101 is cylindrical in shape, hollow inside and open at both ends. Here, the end of the housing 101 that faces the liquid outlet direction is defined as the front end, and the other end is the rear end.

[0150] In some embodiments, the partition 102 is perpendicular to the length direction of the housing 101 and is integrally connected to the interior of the housing 101. The partition 102 divides the interior into a liquid storage chamber 4 and a front chamber 105. The liquid storage chamber 4 is located near the rear end of the housing 101, and the front chamber 105 is located near the front end of the housing 101. By adding the partition 102, the internal space of the housing 101 can be effectively divided, so that each area does not affect the others, which is conducive to achieving different functional effects. For example, the liquid storage chamber 4 can store liquid, while the front chamber 105 can guide airflow into the atomizing head 2, providing a stable air pressure space for the atomizing head 2.

[0151] In some embodiments, the airflow channel 3 is embedded in the side wall of the housing 101 and is arranged adjacent to the liquid storage cavity 4. In this case, the airflow channel 3 can be arranged using the thickness of the housing 101, resulting in a compact structure. Furthermore, by placing the airflow channel 3 inside the side wall of the housing 101, it is also possible to facilitate communication between the vent 32 and the liquid storage cavity 4.

[0152] In some embodiments, mounting holes 1022 are provided on partition 102, and inner needle 21 is mounted on partition 102 through mounting holes 1022. Partition 102 can provide a mounting position for atomizing head 2.

[0153] In some embodiments, the liquid bullet body 1 further includes a front end cover 103 and a rear end cover 104. The rear end cover 104 is disposed on the housing 101 and closes one end of the housing 101 for sealing the liquid storage chamber 4. The rear end cover 104 has an air inlet 1041, and the other end of the airflow channel 3 is connected to the air inlet 1041. The front end cover 103 is disposed on the housing 101 for sealing the front chamber 105. The front end cover 103 has a clearance hole 1031, and the atomizing head 2 extends from inside the front chamber 105 through the clearance hole 1031 to outside the front chamber 105.

[0154] Specifically, the front cover 103 and the housing 101 can be fixedly connected to each other by setting a fastener, and similarly, the rear cover 104 and the housing 101 can be fixedly connected to each other by setting a fastener. The front cover 103 can improve the sealing performance of the front chamber 105, making the structure less prone to air leakage, while the rear cover 104 can ensure the sealing performance of the liquid storage chamber 4 to prevent leakage of beauty fluid.

[0155] Based on the above setup, the arrangement of each component is reasonable and compact, which can make full use of the structural space and optimize and improve the structural compactness.

[0156] In some embodiments, refer to Figure 10The water-light bullet also includes a microneedle chip 12, which is disposed at the front end of the liquid bullet body 1 and adjacent to the atomizing port 201. The microneedle chip 12 has microneedles (not shown). During use, the microneedles can be used to stimulate the skin, thereby forming absorption channels and ultimately promoting the penetration and absorption of the beauty device, thus optimizing and enhancing the skincare effect. It is understood that the microneedle chip 12 is provided with a clearance port 121 to avoid the atomizing port 201, allowing atomized microparticles to be ejected sequentially from the atomizing port 201 and the clearance port 121 of the microneedle chip.

[0157] Reference Figure 13 as well as Figure 14 This application also provides a beauty device, including the aforementioned water light bullet, as well as a beauty device body 10 and an air source 9. The water light bullet is disposed on the beauty device body 10, and the air source 9 is connected to the airflow channel 3 of the water light bullet.

[0158] Based on the above settings, a beauty device with a compact structure and capable of finely atomizing liquid output was obtained.

[0159] In some embodiments, please refer to Figure 15 The beauty device also includes a vibration mechanism 11, which drives the water-light bullet to move back and forth, thereby massaging the skin. The vibration mechanism 11 includes a vibration motor 111 and a vibration connector 112.

[0160] The vibration motor 111 is installed on the beauty device body 10. The vibration connector 112 is connected to the output shaft of the vibration motor 111, and the water light bullet is connected to the vibration connector 112. The vibration motor 111 drives the water light bullet to move back and forth through the vibration connector 112.

[0161] Specifically, in some embodiments, the vibration motor 111 is fixedly mounted on the beauty device body 10, and the vibration connector 112 is a cylindrical mounting sleeve with one end open and the other end connected to the output shaft of the vibration motor 111. At this time, the water light bullet can be plugged and unplugged into the vibration connector 112 through the opening on the vibration connector 112, so that the water light bullet can be replaced, which is conducive to keeping the beauty device hygienic. Correspondingly, a locking component or a magnetic component can be added between the water light bullet and the beauty device body 10. The water light bullet is fixed in the mounting sleeve by the locking component or the magnetic component to achieve the fixed installation of the water light bullet.

[0162] Based on the above configuration, the vibration motor 111 can drive the water-light bullet to vibrate and massage the skin through the vibration connector 112 to promote skin absorption.

[0163] In some embodiments, refer to Figure 16One end of the water-light bullet has microneedles, and the front end of the beauty device body 10 has an interface 1001. The water-light bullet is inserted into the interface 1001. Several electrode elements 13 are around the interface 1001. When the water-light bullet is inserted into the interface 1001, the electrode elements 13 and the microneedles combine to form a care surface.

[0164] In some embodiments, a microneedle chip 12 can be installed at the front end of the water-light bullet. The microneedle chip 12 has microneedles that can vibrate synchronously with the vibration mechanism 11, thereby opening the skin absorption channel and optimizing the promotion effect.

[0165] In addition, the connector 1001 is located at the front end of the beauty device body 10, and the connector 1001 is connected to the opening on the vibration connector 112. The water light bullet is installed into the beauty device through the connector 1001 to improve the compactness of the structure. On this basis, by setting electrode elements 13 around the connector 1001, the electrode elements 13 can be electrically connected to the circuit board 18 inside the beauty device body 10 to obtain electrical energy. At this time, microcurrent can be output during the treatment, thereby further opening the skin absorption channel and further optimizing and improving the penetration effect of the beauty essence.

[0166] It is understandable that the treatment surface formed by the electrode element 13 and the microneedles can be a flat surface or an uneven curved surface. The function of the treatment surface is to fit into the skin so that the electrode element 13 and the microneedles can treat the skin at the same time. The specific outline of the treatment surface is not limited here.

[0167] Reference Figure 17 In some embodiments, the beauty device also includes an information element 191 and a projectile recognition module. The information element 191 is disposed on the water-light projectile, and the information element 191 on different water-light projectiles has different recognition information.

[0168] The projectile recognition module is located on the beauty device body 10 and connected to the information element 191, and is used to read the recognition information on the information element 191.

[0169] Specifically, in some embodiments, the information element 191 is a storage chip, which is disposed on the rear end cover 104 of the liquid bullet body 1 and records the type of beauty liquid of the liquid bullet body 1 to form an identifiable information; the bullet identification module can be configured as a control module on the main control chip, and when the bullet identification module is connected to the information element 191, it can obtain the identification information on the water light bullet.

[0170] In some embodiments, to enable the information element 191 and the projectile recognition module to connect to each other, a first electrical connector 20 is provided on the outer surface of the liquid bullet body 1, and the first electrical connector 20 is connected to the information element 191. A second electrical connector 23 is provided inside the beauty device. Through the contact and cooperation between the first electrical connector 20 and the second electrical connector 23, the information element 191 and the projectile recognition module can be connected to each other. It can also be compatible with the replacement use of water-light bullets. The structure is flexible and well meets the actual use requirements.

[0171] In some embodiments, one of the first electrical connector 20 and the second electrical connector 23 is configured as a contact, and the other is configured as a resilient electrical connector. It is understood that the contact can be located at the rear end cover 104 of the hydrogel, and the resilient electrical connector can be located at the bottom of the insertion interface 1001. It is understood that the resilient electrical connector can be a resilient pin or a conductive elastic sheet. Furthermore, the positions of the contact and the resilient electrical connector can also be located on the peripheral surface of the hydrogel and the inner peripheral surface of the insertion interface 1001, respectively, without limitation.

[0172] Based on the above settings, refer to Figure 18 The first electrical connector 20 and the second electrical connector 23 can stably connect the information element 191 and the projectile identification module to each other, and can effectively read the identification information of different liquid projectile bodies 1.

[0173] In some embodiments, when the beauty device is equipped with a vibration mechanism 11 and a vibration connector 112, the beauty device’s interface 1001 exposes the vibration connector 112, so that when the water-light bullet is plugged into the interface 1001, the water-light bullet can be connected to the vibration connector 112.

[0174] Based on the above configuration, the first electrical connector 20 and the second electrical connector 23 adopt elastic pins and conductive elastic sheets to meet the scenarios of disassembling and using the liquid bullet body 1, which is flexible and reliable.

[0175] Furthermore, a second electrical connector 23 is provided on the vibration connector 112 to achieve the interconnection between the information element 191 and the projectile identification module.

[0176] Based on the above settings, when the water-light bullet is installed on the beauty device body 10, the identification information recorded in the information element 191 is obtained through the bullet identification module, thereby identifying the type of beauty serum. Furthermore, the main control chip is electrically connected to the air source 9 and the vibration mechanism 11 respectively. At this time, the main control chip can control the air source 9 or the vibration mechanism 11 to switch different care modes or adjust the care cycle based on the identification information, thereby achieving refined skin care functions. At the same time, with the flexible conduction of the first electrical connector 20 and the second electrical connector 23, it can also be used in the case where the water-light bullet is detachable, and the user experience is significantly improved.

[0177] In some embodiments, the beauty device further includes a distance sensor 17 and / or a skin tone sensor 14. The distance sensor 17 is disposed at the front end of the beauty device body 10 and is used to detect the distance between the distance sensor 17 and the skin. The skin tone sensor 14 is disposed at the front end of the beauty device body 10 and is used to identify the user's skin tone.

[0178] Specifically, in some embodiments, the distance sensor 17 can be an infrared sensor, which can be installed on the beauty device body 10. The distance sensor 17 faces the user and emits infrared rays towards the user. When the user approaches or moves away from the front of the beauty device, the infrared sensor can obtain the displacement distance. At this time, the infrared sensor can be connected to the main control chip, and the main control chip can convert the displacement distance value into a start / stop signal through a function. When the displacement distance is less than a preset value, the main control chip controls the beauty device's air source 9, vibration mechanism 11, and other components to start. When the displacement distance is greater than the preset value, the main control chip controls the beauty device's air source 9, vibration mechanism 11, and other components to stop, thereby realizing the function of automatically controlling the beauty device's start and stop through distance calculation, and optimizing and improving the user experience.

[0179] In some embodiments, the number of distance sensors 17 is multiple. Multiple distance sensors 17 can acquire multiple distance signals from multiple different angles, and can obtain stable distance signals in the case of edge skin care, so as to avoid the phenomenon of a single distance sensor 17 missing detection, and the start and stop of the beauty device is more accurate.

[0180] Specifically, there are two distance sensors 17, which are located on opposite sides of the front end of the beauty device body 10. This effectively prevents the beauty device from missing detections and causing start-stop errors.

[0181] In other embodiments, the skin tone sensor 14 is electrically connected to the main control chip. The skin tone sensor 14 obtains the user's skin tone and a skin tone signal. The skin tone sensor 14 sends the skin tone signal to the main control chip. The main control chip can control the air source 9 and the vibration mechanism 11 to perform different modes of skin care actions based on the skin tone signal, so as to meet the customized skin care needs of users with different skin tones and optimize and improve the user experience.

[0182] 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.
