Description

Technical Field

[0001] The utility model relates to the technical field of hyaluronic acid analyzers, and in particular to an essence cartridge integrated with a microneedle device. Background Art

[0002] With the development of society and the continuous improvement of economic levels, people are paying more and more attention to maintaining their body shape and appearance while satisfying their own health, and the beauty industry is also developing rapidly. A hydration device is one of the beauty devices. A hydration device stimulates the human skin through microneedles, forming many tiny channels in a short period of time. This allows some essences with active ingredients to penetrate into the skin. This is a beauty method to correct skin defects and can be used for local wrinkle removal, body shaping, scar repair, etc. Specifically, a hydration device will be equipped with a microneedle device. The microneedle device can be a nano-scale microneedle chip. A microneedle chip can be understood as a chip equipped with multiple nano-scale microneedles. When the microneedles act on the human skin, the microneedles can stimulate the human skin, thereby opening millions of channels in the skin epidermis over an area of several square millimeters without damaging the skin epidermis. This allows the active ingredients of the essence to effectively penetrate the skin, stimulating collagen proliferation and cell regeneration, repairing aging cells, and thus achieving a beauty effect.

[0003] When the microneedles of existing hyaluronic acid devices act on the skin, the essence is applied to the surface of the skin by squeezing or natural outflow, or the essence is applied to the skin manually before using the hyaluronic acid device, or the essence is applied to the skin after the hyaluronic acid device acts on the skin. The way of applying the essence, first, it is difficult to control the supply of liquid, which can easily cause excessive supply and lead to waste; secondly, the applied essence remains on the surface of the skin in liquid form, and the active substances need to overcome the surface tension of the liquid before penetrating into the skin, which increases the difficulty of essence absorption; in addition, because the stratum corneum channels opened by the microneedles are very small, it is difficult for the large molecular essence applied to the skin to pass through quickly in large quantities, resulting in slow absorption of the essence and poor absorption effect. A large amount of essence remains on the surface of the skin, resulting in waste of essence. Moreover, after using the hyaluronic acid device, in order to avoid the liquid remaining on the skin surface from dripping and contaminating clothes, the user needs to spend time waiting, which affects the user experience.

[0004] In order to solve the problem mentioned in the previous paragraph, the existing water light device usually designs the essence to be absorbed by the user in the form of a spray. The atomized small molecule essence can be absorbed by the user more quickly. Compared with the traditional method of squeezing out the essence or letting it flow out naturally, firstly, the atomization method is easier to control the supply of liquid and is less likely to cause waste; secondly, the atomized essence can quickly pass through the skin channel into the skin without overcoming the surface tension of the liquid, making the essence easier to absorb; thirdly, the atomized essence molecules are smaller and easier to pass through the skin channel into the skin, so it is absorbed faster and has a better effect. There will be no excess essence left on the skin, thereby reducing the waste of essence. Moreover, after use, the user does not need to wait, which saves the user's time and greatly improves the user experience.

[0005] Furthermore, in order to facilitate users to replace essences, the existing hyaluronic acid analyzers are usually designed with a detachable essence cartridge and a liquid storage chamber for storing the essence is set inside the essence cartridge. However, the essence cartridge and microneedle device of the existing hyaluronic acid analyzers are both separately designed. On the one hand, this leads to a larger external volume of the hyaluronic acid analyzer. On the other hand, when the microneedle device stimulates human skin, the user cannot absorb the essence in time. Therefore, based on the structural design of the hyaluronic acid analyzer with a detachable essence cartridge and the need to atomize the liquid, how to reduce the volume of the hyaluronic acid analyzer and improve the absorption effect of the essence is a technical problem in this field. Utility Model Content

[0006] The purpose of the present utility model is to provide an essence bullet integrated with a microneedle device, which mainly solves the technical problem of how to reduce the volume of a hyaluronic acid water light instrument based on the structural design of the essence bullet and also improve the absorption effect of the essence.

[0014] In one of the technical solutions, in a direction perpendicular to the first direction, the mist outlet is arranged close to the microneedle device, and the distance between the mist outlet and the microneedle device is in the range of 0-2 cm; and / or, in a direction perpendicular to the first direction, multiple mist outlets are arranged close to the microneedle device at intervals.

[0015] In one of the technical solutions, an air outlet and an air supply channel that are interconnected are provided in the essence cartridge, and the air outlet is arranged close to the mist outlet.

[0017] In one of the technical solutions, the essence bomb also includes an atomizing nozzle, which is connected to the main body, and the main body, the atomizing nozzle and the microneedle device are arranged in sequence along the first direction.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0040] See also Figure 1 This embodiment discloses a water light instrument, including a main body 1 and an essence bullet 2, and the essence bullet 2 is detachably connected to the main body 1.

[0041] See also Figure 2 、 Figure 3 、 Figures 5 to 7 The essence cartridge 2 specifically includes a main body 21, a microneedle device 22, and a mist outlet 23. The main body 21 is equivalent to at least part of the shell of the essence cartridge 2. The main body 21 is provided with a liquid storage chamber 211 and a mist outlet 212. The liquid storage chamber 211 is used to store the essence. The mist outlet 212 is connected to the liquid storage chamber 211. The essence in the liquid storage chamber 211 is directly ejected from the mist outlet 212. The mist outlet 23 is used to discharge the misted essence ejected from the mist outlet 212 to the outside so that the user can absorb the misted essence. The microneedle device 22 can be a microneedle wafer or other forms of microneedles. The microneedle wafer can be understood as a plurality of nano-scale microneedles arranged on a wafer. Each microneedle can stimulate the human skin along a first direction (i.e., the X-axis direction) to open the internal channels of the skin.

[0042] Please also refer to Figure 2 、 Figure 3 、 Figures 5 to 7 The microneedle device 22 may be provided with the aforementioned mist outlet 23, and / or the mist outlet 23 may be provided close to the microneedle device 22. Specifically, Figure 6 or Figure 7 As shown, the mist outlet 23 can be designed to surround the microneedle device 22 to be close to the microneedle device 22; Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the microneedle device 22 is provided with at least one through-hole 221, which can also serve as the aforementioned mist outlet 23. Of course, the mist outlet 23 can also be provided alongside and adjacent to the microneedle device 22. It is understood that the mist outlet 23 can be provided only near the microneedle device 22, or only on the microneedle device 22.

[0043] As can be seen from the above, this solution integrates the microneedle device 22 on the essence bomb 2, and sets the mist outlet 23 connected to the outside world directly on the microneedle device 22, or, sets it in a place close to the microneedle device 22, or sets it in the above positions at the same time. Because the mist outlet 23 is close to the microneedle device 22, on the one hand, the size of the water light instrument can be made smaller for users to hold and store. On the other hand, when the microneedle device 22 stimulates human skin, the misted essence can enter the skin quickly and promptly, thereby further improving the absorption effect of the essence. On the other hand, more atomized essence can be sprayed onto the skin area acted upon by the microneedle device 22, which can further promote the penetration of the essence and reduce residue through microneedle penetration. On the other hand, the effective area of the atomized essence and the microneedle device 22 acting on the skin can be the same, thereby greatly improving the skin care efficiency.

[0044] It is to be noted that after the essence cartridge 2 is loaded into the main unit 1, the microneedle device 22 can be fixedly connected to the main unit 1 or slidably connected along the X-axis. At this time, the microneedle device 22 can be manually pressed to stimulate the human skin to open the internal channels of the skin. When the microneedle device 22 and the main unit 1 are slidably connected along the X-axis, as shown in FIG. Figure 1 As shown, a driving device 3 can be designed inside the water light instrument to drive the microneedle device 22 to move along the X-axis, so that the microneedle device 22 can stimulate the human skin along the X-axis. The microneedle device 22 and the host 1 can be connected in a sliding manner along the X-axis in the following two ways:

[0045] Method 1: The microneedle device 22 is fixedly connected to the main body 21. When the essence cartridge 2 is installed in the main body 1, the main body 21 and the main body 1 are slidably connected. At this time, the driving device 3 drives the entire essence cartridge 2 to reciprocate along the X-axis, thereby driving the microneedle device 22 to reciprocate along the X-axis.

[0046] Method 2: The microneedle device 22 and the main body 21 are connected by sliding along the X-axis. When the essence cartridge 2 is installed in the main body 1, the main body 21 and the main body 1 are relatively fixed. At this time, the driving device 3 drives the microneedle device 22 to vibrate back and forth along the X-axis.

[0047] See also Figure 5 or Figure 7 The liquid storage chamber 211, the mist outlet 212 and the microneedle device 22 are preferably arranged in sequence along the X-axis direction, so that the overall structure of the essence bomb 2 can be arranged along the X-axis, thereby further reducing the volume of the water light instrument so that the user can easily hold and store it.

[0048] See also Figure 8The positional relationship between the microneedle device 22, the mist outlet 23 and the mist outlet hole 212 includes five situations. Among them, situation one, situation two and situation three can be understood as the mist outlet hole 212 being arranged on the inner side of the microneedle device 22, and situation four and situation five can be understood as the mist outlet hole 212 being arranged on the outer side of the microneedle device 22 or being arranged on the same plane as the microneedle device 22. In this embodiment, Figure 6 and Figure 7 The essence bomb 2 shown is designed according to the second situation, that is, Figure 6 The microneedle device 22 is provided with a mist outlet 23. At the same time, a mist outlet 23 is also provided on the periphery of the microneedle device 22. Figure 8 and Figure 9 In case 2, case 3 and case 5, a plurality of mist outlets 23 may be arranged on the periphery of the microneedle device 22. When the plurality of mist outlets 23 on the periphery of the microneedle device 22 are interconnected, similar to Figure 6 The structure of the Essence Bullet 2 is shown. Please refer to Figure 6 , in a direction perpendicular to the first direction (ie, the X-axis), the mist outlet 23 is disposed close to the microneedle device 22, and the distance between the mist outlet 23 and the microneedle device 22 is in the range of 0-2 cm; or Figure 9 As shown, in a direction perpendicular to the first direction, a plurality of mist outlets 23 are close to the microneedle device 22 and are spaced apart. In case four, when the mist outlet 212 protrudes relative to the microneedle device 22, the mist outlet 212 can directly serve as the mist outlet 23. It can be understood that the distance between the mist outlet 23 and the microneedle device 22 can be the shortest distance between the edge of the mist outlet 23 and the edge of the microneedle device 22. The mist outlet 23 is arranged on the peripheral side of the microneedle device 22, and the essence spray overflows from the peripheral side of the microneedle device 22, which can make the essence spray easier to diffuse and can be sprayed more evenly on the skin. If the microneedle device 22 is also provided with a mist outlet 23, it can achieve uniform diffusion of the atomized essence while increasing the amount of mist output and improving the beauty effect.

[0049] See also Figure 5 or Figure 7 In this embodiment, the mist outlet hole 212 is preferably designed on the inner side of the microneedle device 22, so that there is a mist outlet channel 213 between the mist outlet hole 212 and the mist outlet 23. The mist essence sprayed from the mist outlet hole 212 will be discharged from the mist outlet 23 along the mist outlet channel 213 and absorbed by the user. The mist outlet channel 213 can be formed directly by digging a hole on the main unit 1 or other components, or it can be formed by stacking multiple components and surrounding them together. In this embodiment, the mist outlet hole 212, the mist outlet channel 213 and the microneedle device 22 are also arranged in sequence along the first direction (i.e., the X-axis direction), so that more atomized essence can be quickly sprayed onto the skin area acted upon by the microneedle device 22 to enhance the absorption effect of the essence.

[0050] Please also refer to Figure 6 and Figure 7 In case one, case two and case three, the mist outlet hole 212 can be aligned with at least one mist outlet 23 (as shown in case one or case two); alternatively, a mist outlet guide 215 can be provided in the mist outlet channel 213, and the mist outlet guide 215 is located between the microneedle device 22 and the mist outlet hole 212. The mist outlet guide 215 is provided with a guide channel 2151, which connects the mist outlet hole 212 and the mist outlet 23 respectively to guide the mist essence to be sprayed outward from the mist outlet 23, reduce the diffusion of the mist essence, and guide more mist essence to the target skin. The guide channel 2151 here is equivalent to at least part of the above-mentioned mist outlet channel 213.

[0051] Please also refer to Figures 6 to 8 As shown in Cases 1, 3 and 5, the essence bomb 2 may further include a care guide 24, which is surrounded by a guide space 241. The above-mentioned microneedle device 22 and the mist outlet 23 are both located in the guide space 241, so that the mist essence sprayed from the mist outlet 212 can be sprayed to a designated area of the human skin under the guidance of the guide space 241. For example, when using a water light instrument, the care guide 24 is in direct contact with the skin, and the mist essence can be accurately attached to the skin area covered by the care guide 24 under the guidance of the guide space 241, further reducing the waste caused by the dissipation of the atomized essence.

[0052] The following describes in detail how the essence in the liquid storage chamber 211 of the essence cartridge 2 is sprayed out from the mist outlet 212 in a mist-like state.

[0053] Please also refer to Figure 6 and Figure 7The essence bomb 2 also includes an atomizing sheet 25 and two conductive parts 26. The atomizing sheet 25 is connected to the main body 21 and blocks the opening of the liquid storage chamber 211. The interior of the atomizing sheet 25 has a pore structure, which connects the liquid storage chamber 211 and the outside world. In other words, this pore structure is equivalent to the above-mentioned mist outlet 212. When the atomizing sheet 25 is energized, the atomizing sheet 25 vibrates, thereby breaking up the molecular structure of the essence transported to the atomizing sheet 25 from the liquid storage chamber 211 and producing a naturally floating mist. The atomized essence can pass through the pore structure and be discharged to the mist outlet channel 213. Since the pore structure inside the atomizing sheet 25 is small, it can limit the leakage of liquid essence in the liquid storage chamber 211 to the outside. The two conductive members 26 are connected to the outer wall of the main body 21, with one conductive member 26 connected to the positive electrode of the atomizing sheet 25 and the other conductive member 26 connected to the negative electrode of the atomizing sheet 25. When the essence cartridge 2 is installed in the main unit 1, the two conductive members 26 are electrically connected to the main unit 1 of the hyaluronic acid analyzer, so that the main unit 1 can provide the necessary electrical energy for the atomizing sheet 25. In addition, the liquid storage chamber 211, the atomizing sheet 25, and the microneedle device 22 are arranged in sequence along the first direction (i.e., the positive direction of the X-axis), thereby making the essence cartridge 2 smaller and, in turn, the hyaluronic acid analyzer smaller, making it easier for the user to hold and store.

[0054] Please refer to the Figure 6 and Figure 7 The essence bomb 2 also includes a liquid guide rod 27 arranged in the liquid storage chamber 211. The liquid guide rod 27 is in direct contact with the atomizer 25. The liquid guide rod 27 is used to guide the essence in the liquid storage chamber 211 to the surface of the atomizer 25, thereby improving the reliability of the atomizer 25 in being able to guide and atomize the essence in the liquid storage chamber 211. The use of the liquid guide rod 27 stabilizes the rate of transporting the essence, thereby improving the stability of the mist output of the atomizer 25.

[0055] Please also refer to Figures 1 to 5In addition to using the above-mentioned atomizing sheet 25 to achieve the mist discharge of the essence, the essence cartridge 2 can also include an atomizing nozzle 28, and the atomizing nozzle 28 is designed to have an air outlet 281 and the above-mentioned mist outlet hole 212, and the air outlet 281 is arranged close to the mist outlet hole 212 to be arranged adjacent to the mist outlet hole 212. In addition, an air supply channel 214 needs to be designed in the main body 21, and this air supply channel 214 and the air outlet 281 are connected to each other. After the essence cartridge 2 is loaded into the main unit 1, when the air pump 4 inside the main unit 1 pumps gas into the air supply channel 214, the gas will be discharged from the air outlet 281. Since the air outlet 281 and the mist outlet 212 are arranged adjacent to each other, the airflow output by the air outlet 281 causes a negative pressure to be formed near the air outlet 281 and the mist outlet 212. Since the air pressure at the mist outlet 212 is lower than the air pressure in the liquid storage chamber 211, the essence liquid in the liquid storage chamber 211 is discharged from the mist outlet 212 in the form of mist along the mist outlet 212. The use of pneumatic misting can greatly reduce the particle size of the spray liquid, improve the spray efficiency, and improve the uniformity of the atomization of the essence liquid. It can be understood that the air outlet 281 is arranged close to the mist outlet 212, and the air outlet 281 can be arranged around part or all of the mist outlet 212, such as Figure 4 and Figure 9 or, the air outlet 281 and the mist outlet 212 may be arranged side by side, or, the mist outlet 212 may be arranged around part or all of the air outlet 281.

[0056] In this embodiment, the main body 21, the atomizing nozzle 28 and the microneedle device 22 are arranged in sequence along the first direction, so that the overall structure of the essence bomb 2 can be arranged along the X-axis, thereby further reducing the volume of the hyaluronic acid analyzer so that the user can easily hold and store it.

[0057] Please also refer to Figure 3 and Figure 4 The air outlet 281 at least surrounds part of the periphery of the mist outlet hole 212. In this embodiment, the mist outlet hole 212 is arranged in the air outlet 281, so that the air outlet 281 completely surrounds the periphery of the mist outlet hole 212. Through such a design, there is gas with a relatively high flow rate in a circle around the mist outlet hole 212, so that a uniform and stable low-pressure state is formed around the mist outlet hole 212, ensuring that the essence in the liquid storage chamber 211 can be sprayed outward from the mist outlet hole 212 in the form of mist, avoiding the spraying of both mist essence and liquid essence at the mist outlet hole 212. At the same time, it also solves the problem of intermittent spraying of the essence at the mist outlet hole 212, and improves the stability of the essence spraying at the mist outlet hole 212. Optionally, the area ratio of the mist outlet hole 212 to the air outlet 281 is in the range of 0.2-0.7, and / or the distance between the mist outlet hole 212 and the air outlet 281 is greater than 0 mm and less than or equal to 0.5 mm.

[0058] Specifically, in this embodiment, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set within the range of 0.2-0.7. For example, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set to 0.2, 0.45, or 0.70. Optionally, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set based on the required mist output. For example, when the required mist output is small, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set to 0.2; when the required mist output is medium, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set to 0.45; when the required mist output is large, the area ratio of the mist outlet hole 212 to the air outlet 281 can be set to 0.70.

[0059] Optionally, the distance between the mist outlet hole 212 and the air outlet 281 can be set within a range greater than 0 mm and less than or equal to 0.5 mm. For example, the distance between the mist outlet hole 212 and the air outlet 281 can be 0.01 mm, 0.25 mm, or 0.5 mm. Optionally, the distance range between the mist outlet hole 212 and the air outlet 281 can be set based on the required mist output. For example, when the required mist output is large, the distance between the mist outlet hole 212 and the air outlet 281 can be set to 0.01 mm; when the required mist output is medium, the distance between the mist outlet hole 212 and the air outlet 281 can be set to 0.25 mm; when the required mist output is small, the distance between the mist outlet hole 212 and the air outlet 281 can be set to 0.5 mm.

[0060] Please also refer to Figure 2 、 Figure 3 and Figure 5 The atomizing nozzle 28 includes a liquid outlet part 282 and a sleeve part 283 sleeved on the outer peripheral side of the liquid outlet part 282. The mist outlet hole 212 passes through the liquid outlet part 282. A gap is provided between the sleeve part 283 and the liquid outlet part 282. This gap forms an air outlet cavity 284. This air outlet cavity 284 is connected to the above-mentioned air supply channel 214. The above-mentioned air outlet 281 is formed at the end of the air outlet cavity 284 away from the air supply channel 214. Through such a design, the gas in the air supply channel 214 will first enter the air outlet cavity 284 and then be discharged from the air outlet 281. The formed air outlet cavity 284 is used to realize that the air outlet 281 can completely surround the outer periphery of the mist outlet hole 212, and the gas flow rate around the mist outlet hole 212 is sufficiently large and the gas flow rate is more uniform, thereby improving the stability of the spray from the mist outlet hole 212.
