Description

A water light instrument Technical Field

[0001] The present application relates to the technical field of beauty instruments, and in particular to a water light instrument. Background Art

[0002] With the development of society and the continuous improvement of economic levels, people are paying more and more attention to the maintenance of their own body shape and appearance while satisfying their own health. The beauty industry is also developing rapidly. A water light instrument is one of the beauty instruments. A water light instrument is an instrument that stimulates the human skin through microneedles, so that many tiny channels are formed in the skin in a short period of time, so that some essences with active ingredients can penetrate into the skin, so as to achieve a beauty method to correct skin defects. It can be used for local wrinkle removal, body shaping, scar repair, etc. Specifically, a water light instrument will be equipped with a microneedle chip. The microneedle chip can be understood as a chip with multiple nano-level 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 of several square millimeters without damaging the skin epidermis. The active ingredients of the essence can effectively penetrate the skin, stimulate collagen proliferation and cell regeneration, repair aging cells, and thus achieve a beauty effect.

[0003] In the related art, when the microneedles of the hyaluronic acid device act on the skin, the essence is applied to the surface of the skin by squeezing or naturally flowing out, 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. Regarding the method of applying the essence, firstly, it is difficult to control the supply of liquid, which can easily cause excessive supply and lead to waste; secondly, the applied essence stays 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 the 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.

Specifically, the microneedle device 2 is designed to be slidably connected to the housing 1 in the X-axis direction, and the driving device 4 is designed to be connected to the housing 1 and the microneedle device 2 respectively. The driving device 4 drives the microneedle device 2 to move back and forth along the X-axis in a straight line, so that the microneedle device 2 can automatically stimulate the skin, thereby optimizing the user experience. The microneedle device 2 slides along the positive direction of the X-axis to stimulate the human skin, and the microneedle device 2 slides along the reverse direction of the X-axis to reset. In addition, as shown in Figure 3, the driving device 4 and the microneedle device 2 can be arranged in sequence along the positive direction of the X-axis, so that the overall structure of the water light instrument can be arranged along the X-axis, thereby reducing the spatial volume of the water light instrument in the radial direction so that the user can easily hold and store it.

[0102] Please refer to Figures 1 to 3 together. The water light instrument also includes a mist outlet 121 connected to the outside world. This mist outlet 121 is used for discharging the atomized essence generated by the atomization device 3; the microneedle device 2 is provided with a mist outlet 121, and / or the mist outlet 121 is arranged close to the microneedle device 2. Specifically, as shown in Figure 3, the mist outlet 121 can be designed to surround the microneedle device 2 to be close to the microneedle device 2, and the microneedle device 2 is provided with at least one through hole 21, and this hole 21 can also serve as the mist outlet 121. Of course, the mist outlet 121 can also be arranged side by side and close to the microneedle device 2. It can be understood that the mist outlet 121 can be set only at a position close to the microneedle device 2, or the mist outlet 121 can be opened only in the microneedle device 2.

[0103] During use, the water light instrument of this solution can use the driving device 4 to drive the microneedle device 2 to slide back and forth, so that the microneedle device 2 can stimulate the human skin, thereby opening the internal channels of the skin, and using the atomizing device 3 to atomize the essence. The atomized small molecule essence will be discharged outward from the mist outlet 121 and eventually penetrate into the interior of the human skin, so that the user can absorb the essence faster. Compared with the traditional method of squeezing out or naturally flowing out the essence, this solution can atomize the essence for the user to absorb. First, the atomization method is easier to control the supply of liquid and is less likely to cause waste; second, the atomized essence can quickly enter the skin through the skin channel without overcoming the surface tension of the liquid, making the essence easier to absorb; third, the atomized essence molecules are smaller and easier to enter the skin through the skin channel, resulting in faster absorption and 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. In addition, this solution sets the mist outlet 121 connected to the outside world directly on the microneedle device 2, or the mist outlet 121 is set near the microneedle device 2, or is set at the above two positions at the same time. Therefore, the mist outlet 121 is close to the microneedle device 2. On the one hand, it can make the size of the water light instrument smaller so that it is easier for users to hold and store it. On the other hand, when the microneedle device 2 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 2, 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 2 acting on the skin can be the same, thereby greatly improving the skin care efficiency.

[0104] Please refer to Figure 3 again. The atomizing device 3 includes a mist outlet 33. The liquid essence is atomized and dispersed outward from the mist outlet 33. The mist outlet 33 is designed on the inner side of the microneedle device 2. There is a mist outlet channel 12 between the mist outlet 33 and the mist outlet 121. The mist essence sprayed from the mist outlet 33 will be discharged outward from the mist outlet 121 along the mist outlet channel 12 and be absorbed by the user. The mist outlet channel 12 can be formed directly by digging a hole in the housing 1 or other components, or it can be formed by stacking multiple components together and surrounding them. In this embodiment, the mist outlet 33, the mist outlet channel 12 and the microneedle device 2 are 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 on by the microneedle device 2 to enhance the absorption effect of the essence.

[0105] Referring to FIG. 21 , the positional relationship among the microneedle device 2, the mist outlet 121, and the mist outlet hole 33 includes five situations. Situations 1, 2, and 3 can all be understood as the mist outlet hole 33 being arranged on the inner side of the microneedle device 2. Situations 4 and 5 can all be understood as the mist outlet hole 33 being arranged on the outer side of the microneedle device 2 or being arranged on the same plane as the microneedle device 2. In this embodiment, the structure shown in FIG. 3 adopts the design of Situation 2, i.e., FIG. 3 provides a mist outlet 121 on the microneedle device 2 and, at the same time, also provides a mist outlet 121 on the periphery of the microneedle device 2. Referring to FIG. 21 and FIG. 22 , in Situations 2, 3, and 5, multiple mist outlets 121 can be arranged on the periphery of the microneedle device 2. When the multiple mist outlets 121 on the periphery of the microneedle device 2 are interconnected, the structure is similar to that shown in FIG. 3 . Referring again to Figure 3 , mist outlet 121 is positioned adjacent to microneedle device 2 in a direction perpendicular to the first direction (i.e., the X-axis), with the distance between mist outlet 121 and microneedle device 2 ranging from 0 to 2 cm. Alternatively, as shown in Figure 22 , multiple mist outlets 121 are positioned adjacent to microneedle device 2 in a direction perpendicular to the first direction and spaced apart. In scenario 4, the extended mist outlet hole 33 corresponds to mist outlet 121.

[0106] Please refer to Figure 21 again. The mist outlet hole 33 in Cases 1, 2, and 3 can be aligned with at least one mist outlet 121 (as shown in Case 1 or 2); or, as shown in Figure 19, a mist outlet guide 9 can be provided in the mist outlet channel 12. The mist outlet guide 9 is located between the microneedle device 2 and the atomizing device 3. The mist outlet guide 9 is provided with a guide channel 91. The guide channel 91 connects the mist outlet hole 33 and the mist outlet 121 respectively to guide the mist essence to be sprayed outward from the mist outlet 121, reducing the diffusion of the mist essence so as to guide more mist essence to the target skin. Among them, the mist outlet guide 9 can be fixed to the housing 1 and does not vibrate with the microneedle device 2. The mist outlet guide 9 can also be designed to be relatively fixed to the microneedle device 2 so as to vibrate with the microneedle device 2.

[0107] Please refer to Figure 3 or Figure 21. The shell 1 in Cases 1 to 5 also includes a care guide 10 (as shown in Cases 1, 3 and 5). This care guide 10 is surrounded by a guide space 101. The above-mentioned microneedle device 2 and the mist outlet 121 are both located in this guide space 101, so that the mist essence sprayed from the mist outlet 33 can be sprayed to the designated area of ​​the human skin under the guidance of the guide space 101. For example, when using the water light instrument, the care guide 10 is in contact with the skin, and the mist essence can be accurately attached to the skin area covered by the care guide 10 under the guidance of the guide space 101, further reducing the waste caused by the dissipation of the atomized essence.

[0108] Referring again to FIG. 3 , the housing 1 further includes a liquid storage chamber 11 in communication with the mist outlet 33 . The liquid storage chamber 11 is used to store essence. The housing 1 further includes a mounting portion 822 , to which the microneedle device 2 is fixed. The liquid storage chamber 11 , the mounting portion 822 , and the microneedle device 2 are sequentially arranged along a first direction (i.e., the positive direction of the X-axis). The driving device 4 drives the mounting portion 822 to reciprocate along the first direction, thereby achieving reciprocating motion of the microneedle device 2 along the first direction. The liquid storage chamber 11, the mounting portion 822 and the microneedle device 2 are arranged in sequence along the first direction, which is conducive to the rational use of the internal space, the realization of a miniaturized design of the product, and the convenience of user holding and storage. At the same time, it is also conducive to the proximity of the mist outlet hole 33 and the microneedle device 2, thereby shortening the distance between the mist outlet hole 33 and the mist outlet 121, shortening the distance from the atomized essence to the mist outlet 121, and reducing the condensation of the atomized essence in the mist outlet channel 12, so as to increase the discharge volume of the atomized essence, thereby improving the absorption rate of the essence.

[0109] In order to achieve the purpose of arranging the liquid storage chamber 11, the mounting portion 822 and the microneedle device 2 in sequence along the first direction (i.e., the positive direction of the X-axis), the atomizing device 3 can be designed as an electric mist-discharging structure or a pneumatic mist-discharging structure. For specific descriptions, please refer to the following two paragraphs:

[0110] Please refer to Figure 3. The atomizing device 3 can be designed to include an atomizing sheet 31, which is arranged at the opening of the liquid storage chamber 11 and has a mist outlet hole 33. Specifically, as shown in Figure 3, the atomizing sheet 31 can be arranged in the mist outlet channel 12 and block the opening of the liquid storage chamber 11 to prevent the liquid essence in the liquid storage chamber 11 from leaking out. At the same time, the interior of the atomizing sheet 31 has a pore structure, which connects the liquid storage chamber 11 with the outside. In other words, this pore structure is equivalent to the above-mentioned mist outlet hole 33. When the atomizing sheet 31 is energized, the atomizing sheet 31 vibrates, thereby breaking up the molecular structure of the essence transported from the liquid storage chamber 11 to the atomizing sheet 31 and producing a naturally floating mist. The atomized essence can pass through the pore structure and be discharged into the mist outlet channel 12. However, since the pore structure inside the atomizing sheet 31 is relatively small, it can limit the liquid essence in the liquid storage chamber 11 from leaking out. The structural design of the essence liquid atomization is realized by using the atomizing sheet 31. Because the atomizing structure is simple, it is easier to achieve the purpose of arranging the liquid storage chamber 11, the mounting portion 822 and the microneedle device 2 in sequence along the first direction (i.e., the positive direction of the X-axis). In addition, the atomizing sheet 31 is arranged between the liquid storage chamber 11 and the mounting portion 822, so that the liquid storage chamber 11, the atomizing sheet 31, the mounting portion 822 and the microneedle device 2 are arranged in sequence along the first direction (i.e., the positive direction of the X-axis), thereby making the hyaluronic acid analyzer smaller and easier for users to hold and store. Specifically, the microneedle device 2 and the atomizing sheet 31 can both be arranged in the mist outlet channel 12, or the atomizing sheet 31, the mist outlet channel 12 and the microneedle device 2 are arranged in sequence along the first direction, and the atomized essence generated by the mist outlet hole 33 can overflow from the peripheral side of the microneedle device 2, or overflow from the hole 21 opened in the microneedle device 2.

[0111] Please refer to Figures 14 to 16. The atomizing device 3 can also be designed to include an air pump 32 and an air outlet 152. The air outlet 152 is arranged near the mist outlet 33 and is connected to the outside. The air pump 32 is used to pump air to the air outlet 152. When the gas is discharged from the air outlet 152, since the air outlet 152 and the mist outlet 33 are arranged adjacent to each other, and the air flow output by the air outlet 152 causes a negative pressure to be formed near the air outlet 152 and the mist outlet 33. Since the air pressure at the mist outlet 33 is lower than the air pressure in the liquid storage chamber 11, the essence in the liquid storage chamber 11 is discharged from the mist outlet 33 along the mist outlet 33 in the form of mist. The misted essence is finally discharged outward along the mist outlet channel 12 and penetrates into the human skin to achieve absorption of the essence. The combined structure of the air pump 32 and the air outlet 152 enables the atomization of the essence liquid, and enables the sequential arrangement of the liquid reservoir 11, the mounting portion 822, and the microneedle device 2 along the first direction (i.e., the positive direction of the X-axis). Furthermore, the pneumatic atomization method significantly reduces the particle size of the spray liquid, improves spray efficiency, and enhances the uniformity of the essence liquid atomization.

[0112] The following describes in more detail the solution of using the atomizing plate 31 to emit mist and the solution of using the air pump 32 to emit mist through two specific embodiments.

[0113] Specific embodiment 1: The atomizing device 3 uses an electric atomizing plate 31.

[0114] Please refer to Figure 2. This embodiment provides a water light instrument, which includes a housing 1, a microneedle device 2, an atomizing sheet 31, a driving device 4, a battery 5 and a circuit board 6. The battery 5 and the circuit board 6 are both installed in the housing 1. The battery 5 and the circuit board 6 are electrically connected. The circuit board 6 is electrically connected to the above-mentioned atomizing sheet 31 and the driving device 4 respectively. The battery 5 can be a dry cell battery or a rechargeable battery. The circuit board 6 can control the charging or discharging of the battery 5. During operation, the battery 5 can provide the required electrical energy to the atomizing sheet 31 and the driving device 4 through the circuit board 6. The circuit board 6 can also be used to control the power of the atomizing sheet 31 or the driving device 4 to adjust the mist output efficiency or adjust the vibration frequency of the microneedle device 2 along the X-axis. In addition, as shown in Figure 3, the battery 5, the driving device 4, and the microneedle device 2 can be arranged in sequence along the positive direction of the X-axis, so that the overall structure of the water light instrument can be arranged along the X-axis, thereby reducing the spatial volume of the water light instrument in the radial direction, so that the user can easily hold the water light instrument for beauty care.

[0115] In other embodiments, the water light instrument can also be provided with a power cord, which is connected to the atomizing plate 31 or the driving device 4, so that the atomizing plate 31 or the driving device 4 can be disconnected from the circuit board 6. The atomizing plate 31 or the driving device 4 can be directly connected to the external power supply through the power cord. At this time, the atomizing plate 31 or the driving device 4 can also be powered on and work.

[0116] In this embodiment, the atomizing sheet 31 does not reciprocate along the X-axis along with the microneedle device 2. In other embodiments, the atomizing sheet 31 may reciprocate along the X-axis along with the microneedle device 2. In this case, the atomizing sheet 31 may be connected to the circuit board 6 via a flexible wire to ensure that the atomizing sheet 31 maintains a reliable electrical connection with the circuit board 6 during the reciprocating X-axis vibration.

[0117] Please refer to Figure 3 again. A liquid guide rod 7 is provided in the liquid storage chamber 11. The liquid guide rod 7 is in direct contact with the atomizer 31. The liquid guide rod 7 is used to guide the essence in the liquid storage chamber 11 to the surface of the atomizer 31, thereby improving the reliability of the atomizer 31 in being able to guide and atomize the essence in the liquid storage chamber 11. The use of the liquid guide rod 7 stabilizes the rate of delivering the essence, thereby improving the stability of the mist output from the atomizer 31.

[0118] Please refer to Figures 3 to 6 together. The housing 1 of this embodiment includes a main housing 80 and a sub-housing 81 that are detachably connected. The mist outlet channel 12 can be arranged in the main housing 80 or in the sub-housing 81. Specifically, the mist outlet channel 12 is set in the sub-shell 81 as an example: the sub-shell 81 includes a main body 17 and a mounting seat 82. The above-mentioned liquid storage chamber 11 and the mist outlet channel 12 are both set in the main body 17, the above-mentioned atomizing sheet 31 is fixed to the main body 17, and the above-mentioned microneedle device 2 is fixed to the mounting seat 82. In other words, the liquid storage chamber 11 and the mist outlet channel 12 are integrated in the sub-shell 81 at the same time. When the sub-shell 81 is taken out, the microneedle device 2 and the atomizing sheet 31 will be separated together relative to the main shell 80. By setting a detachable sub-shell 81, when the essence in the liquid storage chamber 11 is used up, the user can replenish the essence by replacing the sub-shell 81. On the one hand, it can improve the convenience of users using the product. On the other hand, it can prevent users from injecting other unknown liquids into the liquid storage chamber 11 by themselves, thereby preventing users from absorbing unknown liquids when using the hyaluronic acid analyzer, thereby improving the safety of users. In this embodiment, the mounting seat 82 is slidably connected to the main body 17 in a first direction, and the aforementioned drive device 4 is used to drive the mounting seat 82 to reciprocate along the first direction, thereby achieving the function of driving the microneedle device 2 to reciprocate along the first direction. Compared to directly driving the entire auxiliary housing 81 to move, the requirements for the drive device 4 are lower, thereby reducing product costs. Moreover, by driving the microneedle device 2 to move through the driving mounting seat 82, the electrical connection design of the atomizing plate 31 is simpler and the electrical connection is more stable, which is more conducive to improving product stability. In other embodiments, the mist outlet channel 12 can also be provided on the mounting seat 82.

[0119] Specifically, based on the structure of the above-mentioned detachable sub-shell 81, the sub-shell 81 can also include two first conductive members 83 arranged on the outer wall of the main body 17, one of the first conductive members 83 is connected to the positive pole of the atomizing sheet 31, and the other first conductive member 83 is connected to the negative pole of the atomizing sheet 31. Correspondingly, two second conductive members 13 are provided on the inner wall of the main shell 80, and both second conductive members 13 are electrically connected to the above-mentioned circuit board 6. When the sub-shell 81 is installed in the main shell 80, the main shell 80 and the sub-shell 81 are fixedly connected, and one of the second conductive members 13 is in contact with one of the first conductive members 83, and the other second conductive member 13 is in contact with the other first conductive member 83, so that when the sub-shell 81 is installed in the main shell 80, the circuit board 6 can establish an electrical connection with the atomizing sheet 31 through the second conductive member 13 and the first conductive member 83, that is, the circuit board 6 can provide the required electrical energy for the atomizing sheet 31. It is understandable that the contact between the second conductive member 13 and the first conductive member 83 may be elastic contact, which can improve the electrical connection stability between the second conductive member 13 and the first conductive member 83 .

[0120] The auxiliary housing 81 and the main housing 80 may be fixedly connected by a snap-fit ​​connection, or an elastic spring may be provided in the main housing 80 to clamp the outer wall of the auxiliary housing 81, thereby securing the auxiliary housing 81 relative to the main housing 80. The second conductive member 13 may be designed as a spring, so that the second conductive member 13 not only connects the atomizing sheet 31 and the circuit board 6 but also clamps and secures the auxiliary housing 81. In other embodiments, the second conductive member 13 may be a conductive spring pin, in which case the second conductive member 13 generally only serves to electrically connect the atomizing sheet 31 and the circuit board 6.

[0121] In other embodiments, the second conductive member 13 may not be connected to the circuit board 6 , and the second conductive member 13 may be directly connected to an external power source via a power cord. In this case, the atomizing plate 31 may also be powered on and work.

[0122] More specifically, based on the design of the above-mentioned detachable sub-shell 81 and the structure in which the atomizer sheet 31 in the sub-shell 81 is fixed relative to the main shell 80 after the sub-shell 81 is installed in the main shell 80, the driving device 4 of this embodiment is specifically designed to include a driving component 41 and an elastic member 42, wherein the driving component 41 is connected to the shell 1, and the driving component 41 is used to push the mounting seat 82 to move along the positive direction of the X axis, and the elastic member 42 is provided between the mounting seat 82 and the main body 17, and the elastic member 42 will push the mounting seat 82 in the opposite direction of the X axis. 2 applies a force, causing the mounting seat 82 to reset in the opposite direction of the X-axis. The elastic member 42 can be a spring. By placing the elastic member 42 within the secondary housing 81, the drive assembly 41 within the hyaluronic acid device only needs to be designed to push the microneedle device 2 in the positive direction of the X-axis, without having to be designed to pull the microneedle device 2 back. This satisfies the functional requirements of the secondary housing 81 being both removable and capable of reciprocating vibration of the microneedle device 2 within, while also simplifying the connection structure between the drive assembly 41 and the microneedle device 2. In this embodiment, when the secondary housing 81 is installed on the main housing 80, the battery 5, drive assembly 41, atomizer 31, and microneedle device 2 can be optionally arranged sequentially along the positive direction of the X-axis, allowing the overall structure of the hyaluronic acid device to be arranged along the X-axis, thereby reducing the radial spatial volume of the hyaluronic acid device and making it easier for the user to hold the hyaluronic acid device for beauty treatments. It is understandable that the driving device 4 can be designed to include only the driving assembly 41 , and the output shaft of the driving assembly 41 is connected to the auxiliary housing 81 , thereby driving the auxiliary housing 81 to reciprocate along the first direction.

[0123] It can be understood that the secondary housing 81 is equivalent to an essence cartridge that integrates the liquid storage chamber 11, microneedle device 2, atomizing plate 31, mist outlet 121, mist outlet channel 12, mist outlet hole 33, mounting base 82, elastic member 42, and two first conductive members 83. The main body 17 is equivalent to at least a portion of the cartridge case. The remaining portion of the water light instrument, excluding the essence cartridge, can be understood as the main unit. The two second conductive members 13 are mounted on the main unit. When the essence cartridge is removed, the two second conductive members 13 are exposed on the main unit.

[0124] Please refer to Figures 3 to 6 and 7 to 10. The mounting seat 82 is designed to include a seat body 821, the aforementioned mounting portion 822, and a guide portion 823 connected to the mounting portion 822. The mounting portion 822 is used to fix the aforementioned microneedle device 2. The guide portion 823 encloses a clearance space 812. The aforementioned liquid storage chamber 11 is located within this clearance space 812. The liquid storage chamber 11 is provided with a guide groove 811 on its periphery. The guide portion 823 is slidably connected to the guide groove 811. The driving device 4 is used to drive the guide portion 823 to reciprocate along the first direction (i.e., the X-axis direction). Based on the sliding structure design of this mounting seat 82, there are two ways to solve the problem of how to guide the microneedle device 2 to slide in the first direction (i.e., the X-axis direction):

[0125] Method 1: Please refer to Figures 3 to 6. The main body 17 is provided with multiple guide grooves 811 on the outer periphery of the liquid storage chamber 11. The guide grooves 811 extend through the main body 17 along the X-axis direction. Multiple guide portions 823 are provided to enclose and form the avoidance space 812. Each guide portion 823 is inserted through a corresponding guide groove 811 and connected to the base 821. When the secondary housing 81 is installed in the main housing 80, the base 821, the elastic member 42, the liquid storage chamber 11, the mounting portion 822, and the microneedle device 2 are arranged in sequence along the positive direction of the X-axis. More specifically, the drive assembly 41 pushes the base 821 in the positive direction of the X-axis, allowing the guide portion 823 and the microneedle device 2 to approach human skin in the positive direction of the X-axis. One end of the elastic member 42 abuts the main body 17, while the other end abuts the base 821. The elastic member 42 is used to apply an elastic force to the base 821 in the opposite direction of the X-axis. When the drive assembly 41 retreats in the opposite direction of the X-axis, the elastic member 42 pushes the entire mounting base 82 and the microneedle device 2 in the opposite direction of the X-axis, thereby achieving reciprocating vibration of the microneedle device 2 along the X-axis. With this structural design, the drive device 4 only needs to drive the mounting base 82 to drive the microneedle device 2, resulting in a lighter load on the drive device 4 and a longer lifespan. Furthermore, the liquid reservoir 11 is fixed relative to the main housing 80, eliminating vibration caused by the drive device 4 and promoting stable and uniform liquid discharge. In addition, since the structure of the mounting seat 82 is adopted in the auxiliary housing 81, it will occupy more space in the X-axis direction. Therefore, the two first conductive members 83 mentioned above can be arranged on the radial outer surface of the main body 17 (i.e., the outer peripheral surface parallel to the X-axis direction). It can be understood that there is no limit to the number of guide portions 823 and guide grooves 811. Only one guide portion 823 can be provided, and only one corresponding guide groove 811 can be provided, as long as it can guide the overall movement of the mounting seat 82. When only one guide portion 823 and guide groove 811 are provided, the guide portion 823 can be provided in a flat shape, or at least be provided around a portion of the liquid storage chamber 11 (i.e., the guide portion 823 is a cylinder with an arc-shaped cross-section in the direction perpendicular to the X-axis). In this way, the guide portion 823 has a simple structure while ensuring strength and achieving stable guidance. It is understood that when the drive device 4 is designed to include only the drive assembly 41, the output shaft of the drive assembly 41 is connected to the guide portion 823 or is connected to the guide portion 823 through the connection with the seat body 821. Therefore, by driving the guide portion 823 or the seat body 821 to reciprocate in the first direction, the mounting seat 82 is driven to reciprocate in the first direction. The guide portion 823 in this embodiment can be understood as a guide rod portion, and the guide groove 811 in this embodiment is equivalent to a guide hole extending in the first direction.

[0126] Method 2: Please refer to Figures 7 to 10 together. The main body 17 is also provided with the above-mentioned liquid storage chamber 11, mist outlet 121 and guide groove 811. The guide portion 823 includes a first guide portion 826 and a second guide portion 825. The first guide portion 826 is mounted on the outer peripheral side of the main body 17 so that the main body 17 is accommodated in the avoidance space 812 formed therein. The second guide portion 825 is connected to the mounting portion 822 and passes through the guide groove 811 to connect with the first guide portion 826. At this time, the function of the mounting seat 82 being able to slide with the main body 17 in the X-axis direction is also achieved. Based on the structural design of the mounting seat 82, the above-mentioned elastic member 42 can be mounted on the outer wall of the main body 17 and abutted between the first guide portion 826 and the main body 17. The elastic member 42 is compressed when the first guide portion 826 slides along the positive direction of the X-axis, that is, the elastic member 42 applies an elastic force to the first guide portion 826 in the opposite direction of the X-axis. During actual operation, the drive assembly 41 can push the first guide portion 826 to move along the positive direction of the X-axis, allowing the mounting seat 82 and the microneedle device 2 to move toward the human skin along the positive direction of the X-axis. When the drive assembly 41 retreats along the negative direction of the X-axis, the elastic member 42 can push the entire mounting seat 82 and the microneedle device 2 to move along the negative direction of the X-axis, thereby achieving the function of reciprocating vibration of the microneedle device 2 along the X-axis. In addition, because the structure of the mounting seat 82 in the auxiliary housing 81 occupies more space in the radial direction, the two first conductive members 83 can be arranged on the outer surface of the main body 17 in the X-axis direction (i.e., the outer surface perpendicular to the X-axis direction). It is also understood that when the drive device 4 is designed to include only the drive assembly 41, the output shaft of the drive assembly 41 can be connected to the first guide portion 826, thereby driving the first guide portion 826 to reciprocate along the first direction, thereby driving the mounting seat 82 to reciprocate along the first direction.

[0127] In other embodiments, the driving device 4 can drive the entire sub-shell 81 integrated with the microneedle device 2, the liquid storage chamber 11, and the mist outlet 121 to reciprocate along the first direction, thereby realizing the function of the microneedle device 2 to reciprocate in the first direction. At this time, it is also convenient to achieve the purpose of arranging the liquid storage chamber 11, the mounting portion 822 and the microneedle device 2 in sequence along the first direction. However, if this scheme adopts the atomizing sheet 31, since the liquid storage chamber 11 is integrated in the sub-shell 81, the atomizing sheet 31 needs to vibrate along with the sub-shell 81. At this time, the atomizing sheet 31 can be electrically connected to the circuit board 6 by means of a wire to ensure that the circuit board 6 can still stably supply power to the atomizing sheet 31 when the atomizing sheet 31 vibrates. Alternatively, when the entire sub-shell 81 integrated with the microneedle device 2, the liquid storage chamber 11, and the mist outlet 121 reciprocates along the first direction, the structure of the atomizing sheet 31 discharging mist can be replaced by a pneumatic mist discharging structure (see the specific embodiment 2 below for details).

[0128] Referring to Figure 5 , the mounting base 82 may be provided with a cushioning pad 84 on the end facing away from the microneedle device 2. This cushioning pad 84 reduces the impact of the microneedle device 2 striking the skin, further enhancing the user experience. Furthermore, when the drive device 4 and mounting base 82 are connected in an abutting manner, the cushioning pad 84 protects the drive device 4 while the drive device 4 drives the mounting base 82 in the positive direction of the X-axis.

[0129] Please refer to Figures 3, 11 and 12 together. The drive assembly 41 can be designed to include a motor 411, an eccentric wheel 412, a connecting rod 413 and a slider 414, wherein the eccentric wheel 412 is connected to the output shaft of the motor 411, the first end of the connecting rod 413 is connected to the eccentric position of the eccentric wheel 412, so that the first end of the connecting rod 413 can rotate eccentrically relative to the output shaft of the motor 411, the second end of the connecting rod 413 away from the first end is connected to the slider 414, and the connecting rod 413 can rotate universally relative to the eccentric wheel 412 and the slider 414 respectively, and the slider 414 is limited in the housing 1, and the limitation of the housing 1 allows the slider 414 to only slide back and forth along the X-axis. It is understandable that the first end of the connecting rod 413 can also be connected to the center position of the eccentric wheel 412, and the output shaft of the motor 411 is connected to the eccentric position of the eccentric wheel 412, so that the first end of the connecting rod 413 can rotate eccentrically relative to the output shaft of the motor 411.

[0130] During operation, the motor 411 drives the eccentric wheel 412 to rotate, and the first end of the connecting rod 413 rotates eccentrically relative to the output shaft of the motor 411, and the connecting rod 413 can be universally rotated relative to the eccentric wheel 412 and the slider 414 respectively. Therefore, the posture of the connecting rod 413 will change under the drive of the eccentric wheel 412. Due to the change in posture, the distance between the eccentric wheel 412 and the slider 414 also changes. When the eccentric wheel 412 continues to rotate, the connecting rod 413 can pull the slider 414 to reciprocate along the X-axis in the housing 1. When the slider 414 moves along the positive direction of the X-axis, the slider 414 can push the microneedle device 2 outward along the positive direction of the X-axis. The slider 414 pushes the above-mentioned mounting seat 82 to move along the positive direction of the X-axis, so that the microneedle device 2 fixedly connected to the mounting seat 82 can move along the positive direction of the X-axis and stimulate the user's skin.

[0131] Please refer to Figures 3, 11 and 12 again. A guide seat 14 can be fixed in the shell 1, and the above-mentioned slider 414 is limited in this guide seat 14. The guide seat 14 has a guide hole, and the guiding direction of the guide hole is parallel to the first direction. The slider 414 is limited in the guide hole of the guide seat 14 and can slide back and forth relative to the guide seat 14 along the first direction, so that the slider 414 can accurately slide back and forth along the X-axis.

[0132] In this embodiment, the force for the mounting base 82 to return in the negative direction of the X-axis is provided by the elastic member 42. Therefore, the reciprocating movement of the slider 414 along the X-axis in this embodiment serves only to propel the mounting base 82 in the positive direction of the X-axis. In other embodiments, if the elastic member 42 is not provided, the slider 414 can be directly or indirectly connected to the mounting base 82, so that the slider 414 not only propels the mounting base 82 in the positive direction of the X-axis, but also pulls the mounting base 82 back in the negative direction of the X-axis. In this case, the reciprocating vibration function of the microneedle device 2 along the X-axis can also be achieved.

[0133] Please refer again to Figures 3, 11, and 12. To achieve universal rotation of the connecting rod 413 relative to both the eccentric 412 and the slider 414, the connecting rod 413 of this embodiment is designed to form spherical contact with the eccentric 412 and the slider 414. Specifically, the first end of the connecting rod 413 is provided with a first spherical surface 4131, and the eccentric 412 is provided with a recessed first spherical groove 4121. More than half of the first spherical surface 4131 is surrounded by the groove wall of the first spherical groove 4121. This allows the eccentric 412 to push the entire connecting rod 413 in the positive direction of the X-axis, and the eccentric 412 can also pull the entire connecting rod 413 in the negative direction of the X-axis. Similarly, the second end of the connecting rod 413 is provided with a second spherical surface 4132, and the slider 414 is provided with a recessed second spherical groove 4141. More than half of the second spherical surface 4132 is surrounded by the groove wall of the second spherical groove 4141, so that the connecting rod 413 can both push the slider 414 in the positive direction of the X-axis and pull the slider 414 in the negative direction of the X-axis. It is understood that the positions of the spherical grooves and spherical surfaces that achieve spherical contact can be interchanged. For example, by providing spherical grooves at both ends of the connecting rod 413 and spherical surfaces on the eccentric 412 and slider 414, the connecting rod 413 can also achieve spherical contact with the eccentric 412 and slider 414, thereby achieving a universal rotation connection. Because the contact between the connecting rod 413 and the eccentric wheel 412 and the slider 414 is spherical, when the motor 411 drives the eccentric wheel 412 to rotate and drives the slider 414 to reciprocate, the connecting rod 413 has rolling friction with the eccentric wheel 412 and the slider 414, thereby reducing the friction between the connecting rod 413 and the eccentric wheel 412 and the slider 414, thereby reducing noise and improving the stability of the drive.

[0134] Referring again to Figures 3, 11, and 12, in this embodiment, to reduce the difficulty of enclosing the first spherical groove 4121 that covers more than half of the first spherical surface 4131, the eccentric wheel 412 is designed to include two separate connecting blocks 4122. The two connecting blocks 4122 are spliced ​​together to form the first spherical groove 4121. At least one of the two connecting blocks 4122 is connected to the output shaft of the motor 411. Similarly, the slider 414 is designed to include two separate connecting pieces 4142. The two connecting pieces 4142 are spliced ​​together to form the second spherical groove 4141. At least one of the two connecting pieces 4142 is restrained within the housing 1 and is capable of reciprocating relative to the housing 1 along the X-axis. When the connecting piece 4142 slides in the positive direction of the X-axis, it directly or indirectly propels the mounting seat 82 and the microneedle device 2 along the positive direction of the X-axis.

[0135] Please refer to Figures 11 and 12 again. The motor 411, eccentric wheel 412, connecting rod 413 and slider 414 are arranged in sequence along the positive direction of the X-axis, so that the driving component 41 can utilize the internal space of the hyaluronic acid analyzer along the X-axis direction and reduce the space in the radial direction of the hyaluronic acid analyzer, thereby making it easier for users to hold the hyaluronic acid analyzer during the beauty process.

[0136] The driving device 4 can be used to drive other beauty functional parts besides the microneedle device 2. For example, the beauty functional part 2 driven by the driving device 4 to vibrate can also be used for skin massage or automatic makeup application on the skin.

[0137] Specific embodiment 2: The atomizing device 3 adopts an air pump 32.

[0138] Please refer to Figures 13 to 15. This embodiment provides another water light instrument, which includes a housing 1, a microneedle device 2, an atomizing device 3, a driving device 4 and a circuit board 6. The housing 1 is also provided with a liquid storage chamber 11 and a mist outlet channel 12. The microneedle device 2 and the atomizing device 3 are also installed in the housing 1, and the driving device 4 is also used to drive the microneedle device 2 to automatically reciprocate along the X-axis. Different from the first embodiment, the atomizing device 3 of the second embodiment adopts an air pump 32. In addition to being electrically connected to the driving device 4, the circuit board 6 is also electrically connected to the air pump 32, so that the circuit board 6 can provide the required electrical energy to the driving device 4 and the air pump 32 respectively.

[0139] Please refer to Figures 14 to 16. The atomizing device 3 of the second embodiment of the present invention includes a mist outlet 33, an air outlet 152 and an air pump 32. An air outlet channel 15 is provided in the housing 1, and a liquid outlet 111 is provided in the liquid storage chamber 11. The liquid outlet 111 is connected to the mist outlet channel 12, and this liquid outlet 111 is equivalent to the mist outlet 33 in the above-mentioned specific embodiment 1; the air inlet 151 of the air outlet channel 15 is connected to the output port of the air pump 32, and the air outlet 152 of the air outlet channel 15 is arranged adjacent to the mist outlet 33. When the air pump 32 flows to the inlet of the air outlet channel 15, the air inlet 151 of the air outlet channel 15 is connected to the output port of the air pump 32. When gas is pumped into the air port 151, the gas will be discharged from the air outlet 152. When the gas is discharged, since the air outlet 152 and the mist outlet hole 33 are arranged adjacent to each other, and the air flow output by the air outlet 152 causes a negative pressure to be formed at the air outlet 152, because the air pressure at the air outlet 152 is lower than the air pressure in the liquid storage chamber 11, the essence in the liquid storage chamber 11 is discharged outward from the mist outlet hole 33 in the form of mist. The misted essence is finally discharged outward along the mist outlet channel 12 and penetrates into the human skin for the user to absorb the misted essence.

[0140] Please refer to Figure 16 again. The air outlet 152 of the air outlet channel 15 at least surrounds part of the outer periphery of the mist outlet hole 33. In this embodiment, the mist outlet hole 33 is arranged in the air outlet 152 of the air outlet channel 15, so that the air outlet 152 of the air outlet channel 15 completely surrounds the outer periphery of the mist outlet hole 33. Through such a design, there is gas with a relatively high flow rate in a circle around the mist outlet hole 33, so that a uniform and stable low-pressure state is formed around the mist outlet hole 33, ensuring that the essence in the liquid storage chamber 11 can be sprayed outward from the mist outlet hole 33 in the form of mist, avoiding the spraying of both mist essence and liquid essence outward at the mist outlet hole 33, and also solving the problem of intermittent spraying of essence at the mist outlet hole 33, thereby improving the stability of the essence spraying at the mist outlet hole 33.

[0141] Referring to Figure 17 , the air outlet channel 15 can be specifically designed to include a main air outlet path 153, an air outlet cavity 154, and one or more air outlet branch paths 155. The following description will take a case where there are multiple air outlet branch paths 155 as an example. Each air outlet branch path 155 connects the main air outlet path 153 and the air outlet cavity 154. The main air outlet path 153 is provided with the aforementioned air inlet 151, and the cavity wall of the air outlet cavity 154 is provided with the aforementioned air outlet 152. That is, the air outlet 152, the air outlet cavity 154, the air outlet branch paths 155, and the main air outlet path 153 are sequentially connected. During operation, the gas pumped out by the air pump 32 will enter the main outlet path 153 through the air inlet 151 and be diverted into each air outlet branch 155. Then the gas in each air outlet branch 155 converges in the air outlet cavity 154 and finally flows out from the air outlet 152. Through such a design, the gas flow rate is large enough, and the gas flow rate of the air outlet 152 surrounding the outer periphery of the mist outlet 33 can be more uniform when the gas is discharged, so as to further improve the stability of the spray of the mist outlet 33.

[0142] Please refer to Figure 17 again. Based on the structural design of the above-mentioned air outlet channel 15, the liquid storage chamber 11 can be designed to include a connected liquid storage cavity 112 and a liquid outlet channel 113. The above-mentioned mist outlet hole 33 is arranged at one end of the liquid outlet channel 113, and the above-mentioned multiple air outlet branches 155 are collectively arranged around the periphery of the liquid outlet channel 113. The liquid storage cavity 112 is an annular structure, and the liquid storage cavity 112 is annularly arranged around the periphery of the multiple air outlet branches 155. In this design of the liquid storage and air supply structure, the layout of the liquid outlet channel 113 and the air outlet branch 155 corresponds to the layout of the liquid outlet 111 and the air outlet 152, respectively, so that the liquid and gas delivery paths are arranged linearly and the paths are minimized, thereby increasing the mist output efficiency and mist output stability.

[0143] Please refer to Figures 15 to 18. The housing 1 of this embodiment specifically includes an atomizing nozzle 16 and a main body 17, wherein the atomizing nozzle 16 is provided with the above-mentioned adjacently arranged mist outlet holes 33 and the air outlet 152, and the atomizing nozzle 16 specifically includes a liquid outlet part 161 and a sleeve 162. The sleeve 162 is sleeved on the outer peripheral side of the liquid outlet part 161, and the above-mentioned mist outlet hole 33 passes through the liquid outlet part 161. Moreover, a gap is provided between the sleeve 162 and the liquid outlet part 161. It can be understood that a circle of the outer periphery of the liquid outlet part 161 can have a gap with the sleeve 162, and the liquid outlet part 161 can also be sleeved. The connecting piece 162 is directly connected, so that only a partial area of ​​the periphery of the liquid outlet piece 161 has a gap. This gap forms an air outlet cavity 154 between the connecting piece 162 and the liquid outlet piece 161, and the main body 17 is provided with a first air supply channel 171 and the above-mentioned liquid storage chamber 11. The atomizing nozzle 16 is connected to the main body 17, and the air outlet cavity 154 is communicated with the first air supply channel 171. The air outlet 152 is formed at one end of the air outlet cavity 154 away from the first air supply channel 171. This section of the first air supply channel 171 can be understood as including the above-mentioned main air outlet path 153 and the above-mentioned one or more air outlet branches 155.

[0144] Please refer to Figures 15 to 18 again. The housing 1 includes a main housing 80 and a sub-housing 81 that are detachably connected to each other. The sub-housing 81 includes the above-mentioned main body 17 and the atomizing nozzle 16. Optionally, the above-mentioned mist outlet channel 12 is provided in the sub-housing 81. The above-mentioned driving device 4 is fixed to the main housing 80 and connected to the sub-housing 81. When the essence in the liquid storage chamber 11 is used up, the user can remove the sub-housing 81 relative to the main housing 80 and replace it with a new sub-housing 81, thereby improving the convenience of product use and user experience. In addition, the sub-housing 81 also includes a mounting base 82 connected to the main body 17. The above-mentioned microneedle device 2 is fixed to this mounting base 82. The main body 17, the atomizing nozzle 16, the mounting base 82 and the microneedle device 2 are arranged in sequence along the first direction (i.e., the X-axis direction). In other words, when the secondary housing 81 is removed from the main housing 80, the main body 17 with the liquid storage chamber 11, the atomizing nozzle 16, the mounting base 82, and the microneedle device 2 are all separated from the main housing 80. The aforementioned drive device 4 remains connected to the secondary housing 81 and is used to drive the entire secondary housing 81 to reciprocate along the X-axis, thereby enabling the microneedle device 2 to reciprocate along the X-axis. The microneedle device 2 is integrated into the secondary housing 81 and can be replaced during the use cycle of the secondary housing 81, ensuring the hygienic and safe use of the product. In addition, the reciprocating motion of the microneedle device 2 with the secondary housing 81 can also simplify the overall structural design of the secondary housing 81.

[0145] As can be seen from the above, the sub-shell 81 integrates the microneedle device 2, the liquid storage chamber 11, the mist outlet channel 12 and the first air supply channel 171 at the same time, and the first air supply channel 171 is connected to the air outlet 152 through the air outlet cavity 154. Therefore, the air pump 32 only needs to pass gas into the first air supply channel 171 to spray outward at the air outlet 152. Based on the structural design with a detachable sub-shell 81, please refer to Figures 14 and 18. The driving device 4 can be designed to include a connected driving mechanism 43 and a slide 44, wherein the driving mechanism 43 is arranged on the main shell 80, and the slide 44 is designed to be slidably connected to the main shell 80 along the X-axis direction. The driving mechanism 43 is used to drive the slide 44 to move back and forth in a straight line along the X-axis direction. The sub-shell 81 is detachably connected to the slide 44. When the sub-shell 81 is installed on the slide 44, the sub-shell 81 and the slide 44 are fixedly connected. When the driving mechanism 43 drives the slide 44 to move back and forth in a straight line, the entire sub-shell 81 will also follow the slide 44 to vibrate back and forth along the X-axis, thereby realizing the function of the microneedle device 2 to vibrate back and forth along the X-axis. In addition, a first gas channel 441 is provided within the slide 44. This first gas channel 441 is connected to the output port of the air pump 32. When the auxiliary housing 81 is mounted on the slide 44, the first gas channel 441 will be connected to the first gas supply channel 171. At this time, the air pump 32 only needs to pump gas into the first gas channel 441, and the gas pumped by the air pump 32 will be ejected outward through the first gas supply channel 171 and the gas outlet 152. In addition, since the slide 44 with the first gas channel 441 is constantly vibrating back and forth relative to the main housing 80 during operation, to ensure that the air pump 32 can stably and reliably pump gas into the first gas channel 441, the first gas channel 441 is connected to the output port of the air pump 32 via a soft air pipe 45.

[0146] Referring again to FIG. 18 , the drive mechanism 43 may be designed to include a motor 431, a cam 432, and a bearing 433. The motor 431 is fixed to the main housing 80, the cam 432 is fixedly connected to the output shaft of the motor 431, and the bearing 433 is sleeved on the outer wall of the cam 432 so that the inner ring of the bearing 433 is fixedly connected to the cam 432. The slide 44 is provided with a groove 442 into which the bearing 433 is embedded. When the motor 431 drives the cam 432 to rotate eccentrically, the bearing 433 also rotates eccentrically with the cam 432. The outer ring of the bearing 433 applies thrust to the groove wall of the groove 442, thereby enabling the slide 44 to reciprocate relative to the main housing 80 along the X-axis. The bearing 433 prevents the cam 432 from directly colliding with the groove wall of the groove 442, thereby reducing the vibration caused by the direct collision and the wear of the outer wall of the cam 432 or the groove wall of the groove 442, thereby improving the reliability and stability of the drive mechanism 43 in driving the slide 44 to reciprocate.

[0147] In this embodiment, an elastic member 85 is provided between the mounting seat 82 and the main body 17, or an elastic member 85 is provided between the mounting seat 82 and the atomizing nozzle 16. Referring to Figures 15, 17, and 18, the elastic member 85 provided between the mounting seat 82 and the atomizing nozzle 16 is used as an example for explanation. The elastic member 85 may be a compression spring. By providing the elastic member 85, the elastic direction of the elastic member 85 includes a direction parallel to the X-axis. When the driving device 4 drives the auxiliary housing 81 and the microneedle device 2 to move together along the positive direction of the X-axis and causes the microneedle device 2 to act on human skin, the force exerted by the microneedle device 2 on the human skin can be buffered, thereby improving the user experience.

[0148] Please refer to Figures 15, 17, and 18 again. The main body 17 includes a liquid core 172 and a casing 173. The liquid core 172 is provided with the above-mentioned liquid outlet channel 113, and the casing 173 is provided with the above-mentioned annular liquid storage chamber 112. The casing 173 is arranged on the outer periphery of the liquid core 172 so that the liquid storage chamber 112 can be arranged around the outer periphery of the liquid outlet channel 113. The casing 173 and the liquid core 172 are both provided with a through hole 174 for connecting the liquid storage chamber 112 and the liquid outlet channel 113. The opening at one end of the liquid outlet channel 113 away from the through hole 174 forms the above-mentioned mist outlet hole 33. The design of this liquid storage structure is simple in structure and easy to manufacture and process. In addition, the liquid transportation path is short, which makes the liquid discharge smooth and the product stability good. Furthermore, a first seal 18 is disposed between the core 172 and the casing 173, at the location of the through-hole 174. The first seal 18 is used to prevent the essence within the liquid reservoir 112 and the liquid outlet channel 113 from overflowing. Specifically, the first seal 18 comprises two sealing rings, each of which is disposed around the outer periphery of the core 172. The two sealing rings are spaced apart, and the through-hole 174 connecting the liquid reservoir 112 and the liquid outlet channel 113 is disposed between the two sealing rings. It is understood that the first seal 18 can also be disposed between the core 172 and the casing 173 and around the outer periphery of the through-hole 174. Specifically, a retaining groove surrounding the through-hole 174 can be formed on the outer sidewall of the core 172 or the inner sidewall of the casing 173. The first seal 18 is disposed in this retaining groove and is held between the core 172 and the casing 173.

[0149] For more specific details, please refer to Figures 15, 17, and 18 again. The liquid core 172 is provided with the above-mentioned main outlet path 153 at one end away from the mist outlet hole 33, and the other end of the liquid core 172 is provided with the above-mentioned one or more outlet branches 155. A second seal 19 is provided between the liquid core 172 and the sleeve 162. The second seal 19 is used to seal the connection between the liquid core 172 and the atomizing nozzle 16 to limit the essence in the liquid outlet channel 113 or the air outlet cavity 154 from overflowing. It is understandable that the main outlet path 153 can be formed in the liquid core 172, or in the sleeve 173, or can be formed by the liquid core 172 and the sleeve 173 together, which is not limited here.

[0150] Please refer to Figures 19 and 20. In addition to the structure of the liquid storage chamber 11 including the liquid outlet channel 113 and the liquid storage cavity 112 arranged around the outer periphery of the liquid outlet channel 113, the liquid storage chamber 11 can also be a structure including multiple liquid storage channels 114 connected in series, wherein the end of the last liquid storage channel 114 is provided with a liquid outlet hole 115. Based on this structure of the liquid storage chamber 11, the main body 17 can be designed to include a liquid core 172, a third sealing member 175 and a fourth sealing member 176, wherein the liquid core 172 is provided with the multiple liquid storage channels 114 that penetrate and are connected in series, and the liquid core 172 is located between the third sealing member 175 and the fourth sealing member 176, so that the third sealing member 175 and the fourth sealing member 176 can both be used to limit the essence in the liquid storage channel 114 from overflowing outwards, and the third sealing member 175 and the fourth sealing member 176 can be used to limit the essence in the liquid storage channel 114 from overflowing outwards. 75 is provided with a liquid outlet channel 177, which is connected to the liquid outlet hole 115 of the last liquid storage channel 114. The liquid outlet channel 177 passes through the third sealing member 175. The aforementioned mist outlet hole 33 is formed at the end of the liquid outlet channel 177 away from the liquid core 172. Specifically, the liquid outlet member 161 of the atomizing nozzle 16 is connected to the third sealing member 175, and the liquid outlet port 111 passes through the liquid outlet member 161, so that the mist outlet hole 33 is connected to the end of the liquid outlet channel 177 away from the liquid core 172. The flow path of the essence can be summarized as follows: the essence flows out of the liquid outlet hole 115 of the last liquid storage channel 114 and enters the liquid outlet channel 177. After passing through the entire liquid outlet member 161, it is sprayed out from the mist outlet hole 33 in the form of mist. More specifically, the liquid core 172 may also be provided with one or more of the aforementioned outlet branches 155. The fourth sealing member 176 may be provided with the aforementioned main outlet path 153. The sleeve 162 of the atomizing nozzle 16 may be connected to the end of the third sealing member 175 facing away from the liquid core 172. Furthermore, the sleeve 162 and the third sealing member 175 together enclose and form the aforementioned outlet cavity 154. The outlet port 152 is formed at the end of the outlet cavity 154 away from the liquid core 172, thereby achieving sequential communication between the outlet port 152, the outlet cavity 154, the outlet branches 155, and the main outlet path 153. Furthermore, the liquid storage channel 114 within the liquid core 172 is not directly connected to any of the outlet branches 155, thereby preventing liquid essence in the liquid storage channel 114 from flowing into the outlet branches 155. The design of this liquid storage structure can increase the liquid storage space without increasing the radial size because multiple liquid storage channels 114 connected in series can fully utilize the volume space of the liquid core 172, thereby reducing the frequency of users replacing the sub-shell 81 and improving user experience.

[0151] Referring to Figure 15 , to ensure a good misting effect, the area ratio of the mist hole 33 to the air outlet 152 is in the range of 0.2-0.7, and / or the spacing between the mist hole 33 and the air outlet 152 is greater than 0 mm but less than or equal to 0.5 mm. In this embodiment, the area ratio of the mist hole 33 to the air outlet 152 can optionally be set within the range of 0.2-0.7. For example, the area ratio of the mist hole 33 to the air outlet 152 can be set to 0.2, 0.45, or 0.70. Optionally, the area ratio of the mist outlet 33 and the air outlet 152 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 33 and the air outlet 152 can be set to 0.2; when the required mist output is medium, the area ratio of the mist outlet 33 and the air outlet 152 can be set to 0.45; when the required mist output is large, the area ratio of the mist outlet 33 and the air outlet 152 can be set to 0.70.

[0152] Optionally, the distance between the mist outlet 33 and the air outlet 152 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 33 and the air outlet 152 can be 0.01 mm, 0.25 mm, or 0.5 mm. Optionally, the distance range between the mist outlet 33 and the air outlet 152 can be set based on the required mist output. For example, when the required mist output is large, the distance between the mist outlet 33 and the air outlet 152 can be set to 0.01 mm; when the required mist output is medium, the distance between the mist outlet 33 and the air outlet 152 can be set to 0.25 mm; when the required mist output is small, the distance between the mist outlet 33 and the air outlet 152 can be set to 0.5 mm.

[0153] Referring to Figures 18 and 19 , the wall of the liquid storage chamber 11 is provided with a vent 116 that communicates with the outside world. This vent 116 allows the air pressure within the liquid storage chamber 11 to always be equal to the outside atmospheric pressure, resolving the problem of the air pressure within the liquid storage chamber 11 becoming too low as the essence is consumed, making it difficult to dispense the essence. This ensures that all the essence within the liquid storage chamber 11 can be stably and effectively dispensed. To prevent the essence within the liquid storage chamber 11 from leaking outward through the vent 116 , a waterproof, breathable member can be provided at the vent 116 . For example, the water-permeable, breathable member can be a waterproof, breathable membrane used in the battery field. This waterproof, breathable membrane has the property of isolating liquid from flowing in or out while allowing air to pass freely through the membrane.

[0154] In summary, the hydrating device of this embodiment can also atomize the essence for the user to absorb, so that the user will not have too much essence on the skin during use, thereby reducing the waste of essence. It also allows the user to use it without waiting, thereby saving the user's time and improving the absorption effect of the essence.

[0155] Please refer to Figure 23. An embodiment of the present application provides a liquid storage tank structure of a beauty instrument. This liquid storage tank can be set in the beauty instrument, and can also be designed to be detachably connected to the main body of the beauty instrument. The liquid storage tank structure mainly includes a main body 177 and a liquid injection valve 22, wherein a liquid storage chamber 11 is provided in the main body 177. The liquid storage chamber 11 is used to store the liquid required for beauty care, such as water or essence, for the user to absorb water or essence. A liquid inlet 212 and a liquid outlet 111 are also provided on the main body 177. The liquid inlet 212 and the liquid outlet 111 are respectively connected to the liquid storage chamber 11. The liquid needs to be replenished into the liquid storage chamber 11 from the liquid inlet 212, and the liquid in the liquid storage chamber 11 is discharged outward through the liquid outlet 111 for the user to absorb. Among them, the injection valve 22 is a plastic part with deformation characteristics as a whole. The injection valve 22 is preferably a duckbill valve. The injection valve 22 blocks the liquid inlet 212 to prevent the liquid in the liquid storage chamber 11 from leaking out from the liquid inlet 212. The injection valve 22 is provided with an injection port 221, and this injection port 221 is in a normally closed state when it is not stretched open by external force.

[0156] Please refer to Figure 25. Before the user needs to add liquid to the liquid storage chamber 11 of this solution, they can mix the pre-prepared freeze-dried powder and solvent to obtain an essence, and then use the perfusion tool 23 to extract the obtained essence. When the user needs to add liquid to the liquid storage chamber 11 of this solution, they need to insert the perfusion tool 23 into the liquid injection valve 22. The perfusion tool 23 opens the liquid injection port 221 of the liquid injection valve 22 and adds liquid to the liquid storage chamber 11. When the liquid is fully replenished, the perfusion tool 23 is withdrawn from the liquid injection valve 22, and the liquid injection port 221 will automatically close. With this solution, when the user replenishes liquid, regardless of whether the liquid storage tank or the beauty instrument is placed horizontally or accidentally knocked over, the liquid in the liquid storage chamber 11 will not leak out, thereby greatly improving the user experience. Furthermore, since the liquid filling port 221 of the liquid filling valve 22 has the characteristic of automatically closing after the liquid is replenished, the structure of the liquid storage tank of this solution is simpler, which reduces the cost of the product and the difficulty of assembly, and the structure using the liquid filling valve 22 has higher sealing reliability.

[0157] Please refer to Figures 23 and 26 together. The filling valve 22 can be optionally accommodated entirely in the liquid storage chamber 11. In order to enable the perfusion tool 23 to be inserted into the filling valve 22, the main body 177 is provided with an opening 214 at a position adjacent to the filling valve 22. The opening 214 is designed to be opposite to the filling port 221 of the filling valve 22, so that the perfusion tool 23 can be inserted into the filling valve 22 by extending into the opening 214, that is, the perfusion tool 23 can open the filling port 221 by inserting into the opening 214. By adopting such a design, the filling valve 22 can be hidden in the liquid storage chamber 11 while realizing the function of the perfusion tool 23 to replenish liquid into the liquid storage chamber 11, thereby improving the appearance of the liquid storage tank.

[0158] Referring again to FIG. 23 , the main body 177 is provided with an air vent 116 that connects the liquid storage chamber 11 with the outside world, allowing the air pressure inside the liquid storage chamber 11 to balance with the outside air pressure. Specifically, as the liquid in the liquid storage chamber 11 gradually depletes, the air pressure inside the liquid storage chamber 11 decreases. At this time, outside air will enter the liquid storage chamber 11 through the air vent 116, ensuring that the air pressure inside the liquid storage chamber 11 can increase to balance with the outside air pressure, thereby preventing the inability to discharge liquid due to excessively low air pressure inside the liquid storage chamber 11. In other words, the stability and reliability of the liquid discharge are ensured. When liquid is replenished in the liquid storage chamber 11, the gas inside the liquid storage chamber 11 will be discharged outwardly through the air vent 116, preventing the abnormal discharge of liquid due to excessive air pressure inside the liquid storage chamber 11 after the liquid is replenished. Optionally, the diameter of the air hole 116 is 0.5mm-1.5mm. If the diameter of the air hole 116 is too small, the air pressure in the liquid storage chamber 11 and the external air pressure will be balanced more slowly. If the diameter of the air hole 116 is too large, the risk of leakage will be increased.

[0159] In this embodiment, in order to reduce the risk of liquid in the liquid storage chamber 11 leaking outward along the air vent 116, the air vent 116 can be designed in the top area as shown in Figure 23. Because the liquid in the liquid storage chamber 11 is located below the liquid storage chamber 11 due to its own gravity, as long as the height of the air vent 116 is higher than the liquid level, the risk of liquid leaking outward from the air vent 116 can be reduced. In addition, when injecting liquid, since more bubbles will be formed at the liquid inlet 212, in order to prevent the bubbles from spreading into the air vent 116 and causing blockage of the air vent 116, and also to prevent the liquid from splashing into the air vent 116 and leaking outward along the air vent 116 due to the bursting of bubbles, the air vent 116 can be designed to be set away from the liquid inlet 212 as shown in Figure 23, or the air vent 116 can be set close to the liquid inlet 212 as shown in Figure 27. However, when the air vent 116 is set close to the liquid inlet 212, a blocking rib 216 needs to be set in the liquid storage chamber 11, and the blocking rib 216 is used to separate the air vent 116 and the liquid inlet 212 to prevent the bubbles at the liquid inlet 212 from spreading to the air vent 116, and to prevent the liquid from splashing into the air vent 116 when the bubbles burst.

[0160] Please refer to Figures 25 and 27 together. A protrusion 217 is provided in the liquid storage chamber 11. A second gas channel 2171 is provided in the protrusion 217. The second gas channel 2171 connects the liquid storage chamber 11 with the outside world. The aforementioned vent 116 is formed at one end of the second gas channel 2171. The protrusion 217 extends in a direction close to the liquid inlet 212, bringing the vent 116 close to the liquid inlet 212. The aforementioned blocking rib 216 separates the protrusion 217 and the liquid inlet 212. Through this design, the outer wall of the protrusion 217 can block the liquid in the liquid storage chamber 11, solving the problem of liquid leaking outward along the vent 116 when the liquid storage tank is tilted, thereby further reducing the risk of leakage.

[0161] Referring again to FIG. 25 , the liquid storage structure further includes a liquid absorbing member 24 connected to the main body 177 . The liquid absorbing member 24 has both liquid absorbing and breathable properties. For example, the liquid absorbing member 24 is a sponge and is positioned along the path connecting the vent 116 to the outside world. The liquid absorbing properties of the liquid absorbing member 24 can absorb liquid that leaks out of the vent 116 , preventing the liquid from leaking to the outside world or to other parts of the beauty instrument and causing damage to the beauty instrument. In other words, the provision of the liquid absorbing member 24 can further reduce the risk of liquid leakage. The breathable properties of the liquid absorbing member 24 ensure that the air pressure inside the liquid storage chamber 11 remains consistent with that outside, thereby ensuring high stability and reliability in the discharge of liquid from the liquid storage chamber 11 .

[0162] Please refer to Figures 23 and 24 together. The liquid storage tank of this solution also includes an atomizing nozzle 16, which specifically includes a liquid outlet part 161 and a socket part 162. The liquid outlet part 161 is provided with a mist outlet hole 33, and this mist outlet hole 33 is connected to the liquid outlet 111 of the main body 177. The socket part 162 is sleeved on the outer periphery of the liquid outlet part 161 and forms an air outlet 152 between the liquid outlet part 161. This air outlet 152 and the mist outlet hole 33 are arranged adjacent to each other. A second air supply channel 218 connected to the air outlet 152 is also provided in the main body 177. When gas is pumped into the second air supply channel 218, the gas will flow out from the air outlet 152. Since the air outlet 152 and the mist outlet 33 are arranged adjacent to each other, and the airflow output by the air outlet 152 forms a negative pressure near the mist outlet 33, and the air pressure at the mist outlet 33 is lower than the air pressure in the liquid storage chamber 11, the essence in the liquid storage chamber 11 is discharged from the mist outlet 33 in the form of mist along the mist outlet 33, and finally penetrates into the human skin to achieve the absorption of the essence. Through such a design, the liquid storage tank can realize the function of atomizing and discharging the essence. The use of pneumatic misting can greatly reduce the particle size of the spray liquid, improve the spray efficiency, improve the atomization uniformity of the essence, and improve the absorption effect of the essence. Optionally, the liquid outlet member 161 is sealedly connected to the main body 177, and the sleeve 162 is also sealedly connected to the main body 177, so that the gas in the second air supply channel 218 can only be discharged from the air outlet 152, and the gas in the second air supply channel 218 cannot be discharged from the gap between the liquid outlet member 161 and the main body 177 or the gap between the sleeve 162 and the main body 177. Optionally, the air outlet 152 is annularly arranged around the outer periphery of the mist outlet hole 33. Through this design, a large flow rate of gas is present around the entire periphery of the mist outlet hole 33, thereby forming a uniform and stable low-pressure state around the mist outlet hole 33, ensuring that the essence in the liquid storage chamber 11 can be sprayed outward from the mist outlet hole 33 in the form of mist, reducing the possibility of both mist and liquid essence being sprayed outward from the mist outlet hole 33. At the same time, it also solves the problem of intermittent spraying of the essence at the mist outlet hole 33 and improves the stability of the essence spraying at the mist outlet hole 33.

[0163] Please refer to Figure 23. The liquid storage chamber 11 includes a connected liquid storage cavity 112 and a liquid outlet channel 113. The liquid storage cavity 112 is preferably annularly surrounding the outer periphery of the liquid outlet channel 113. The above-mentioned liquid outlet port 111 is formed at the end of the liquid outlet channel 113. The aperture of the liquid outlet channel 113 is 0.5mm-2mm. If the aperture of the liquid outlet channel 113 is too small, it is not conducive to the outward misting. If the aperture of the liquid outlet channel 113 is too large, the risk of leakage is increased, and it also has a certain impact on the spray effect.

[0164] The present application also provides a beauty device, comprising a main body 60 and a detachable essence bottle 70 relative to the main body 60. The essence bottle 70 includes the aforementioned liquid reservoir structure. When the essence bottle 70 only has the function of storing liquid and allowing it to be discharged, the liquid reservoir structure is the essence bottle 70. By designing a detachable essence bottle 70, the user can remove the essence bottle 70 and refill the liquid reservoir 11. That is, the user does not need to hold the entire, bulky beauty device when refilling the liquid reservoir 11, making it easier for the user to refill the liquid, thereby improving the user experience. In this embodiment, in addition to storing liquid and allowing it to be discharged, the essence bottle 70 also integrates a microneedle device 2. The microneedle device 2 is connected to the main body 177. The microneedle device 2 can be a microneedle wafer or other form of microneedle. A microneedle wafer can be understood as a wafer with multiple nanometer-scale microneedles. Each microneedle can stimulate the human skin to open the skin's internal channels, thereby allowing the user to better absorb the essence. By integrating the microneedle device 2 into the essence bottle 70, the overall size of the beauty device is reduced, making it easier for the user to hold or store. It should be noted that the connection between the microneedle device 2 and the main body 177 can be either fixed or sliding. When the microneedle device 2 and the main body 177 are fixedly connected, the user must manually apply force to stimulate the skin. When the microneedle device 2 and the main body 177 are slidingly connected, a drive device can be provided within the main unit 60 to automatically drive the microneedle device 2 to vibrate back and forth, causing the microneedle device 2 to stimulate the human skin. Furthermore, when the essence bottle 70 is provided with the aforementioned atomizing nozzle 16, an air pump is also required within the main unit 60 to pump gas into the aforementioned second air supply channel 218, thereby achieving the function of atomizing and spraying the liquid within the essence bottle 70.

[0165] More specifically, referring to FIG26 , the essence bottle 70 is provided with a first foolproof structure 71. Referring to FIG29 and FIG30 , the main unit 60 is provided with a second foolproof structure 61. When the essence bottle 70 is connected to the main unit 60 of the beauty device, the first foolproof structure 71 and the second foolproof structure 61 cooperate to connect, positioning the aforementioned vent 116 upward, as shown in FIG23 or FIG27 . At this point, the vent 116 communicates with the top area within the liquid storage chamber 11. The liquid within the liquid storage chamber 11 is then held at the bottom due to gravity, while the vent 116 is located above the liquid level, thereby reducing the risk of liquid leakage through the vent 116. Preferably, the first foolproof structure 71 is designed as a rib structure, and the second foolproof structure 61 is designed as a slot structure that cooperates with the rib.

[0166] Please refer to Figures 31 to 34 and 36. This embodiment provides an atomization bin of a beauty instrument. This atomization bin can be set in the beauty instrument and cannot be disassembled, or it can be designed to be detachably connected to the host of the beauty instrument. This atomization bin mainly includes a main body 17 and an atomization nozzle 16. A liquid storage chamber 11 and a third air supply channel 312 are provided in the main body 17. The liquid storage chamber 11 is used to store water or essence so that the user's skin can replenish water or absorb the essence. The atomization nozzle 16 includes a liquid outlet 161 and a sleeve 162. The liquid outlet 161 is provided with a liquid outlet 111, which is communicated with the liquid storage chamber 11. The sleeve The connecting piece 162 is sleeved on the outside of the liquid outlet piece 161 and forms an air outlet 152 arranged adjacent to the liquid outlet 111 between the liquid outlet piece 161. The air outlet 152 is connected to the above-mentioned third air supply channel 312. When gas is pumped into the third air supply channel 312, the gas will be discharged from the air outlet 152. Since the air outlet 152 and the liquid outlet 111 are arranged adjacent to each other, and the air flow output by the air outlet 152 causes a negative pressure to be formed near the liquid outlet 111. Since the air pressure at the liquid outlet 111 is lower than the air pressure in the liquid storage chamber 11, the liquid in the liquid storage chamber 11 is discharged from the liquid outlet 111 in the form of mist along the liquid outlet 111. Optionally, the liquid outlet part 161 is sealedly connected to the main body 17, and the socket part 162 is also sealedly connected to the main body 17, so that the gas in the third air supply channel 312 can only be discharged from the air outlet 152, and the gas in the third air supply channel 312 cannot be discharged from the gap between the liquid outlet part 161 and the main body 17 and the gap between the socket part 162 and the main body 17.

[0167] By designing the physical components as described above so that the atomizing chamber has a liquid storage chamber 11, an air outlet 152, and a liquid outlet 111, it is convenient to adjust the relative positions of the air outlet 152 and the liquid outlet 111 to optimize the misting effect. Specifically, the relative positions of the air outlet 152 and the liquid outlet 111 can be adjusted in the following two ways:

[0168] Method 1: The socket 162 and the main body 17 can be bonded together by glue, so that a glue layer 330 is connected between the socket 162 and the main body 17. Since the glue layer 330 has a certain viscosity, the position of the socket 162 can be fine-tuned before the glue layer 330 is completely solidified, so that the position of the air outlet 152 relative to the liquid outlet 111 can be fine-tuned; at the same time, when the glue layer 330 fills the gap between the socket 162 and the main body 17, the glue layer 330 also plays a role in sealing the gap between the socket 162 and the main body 17, so that the gas in the third air supply channel 312 cannot leak out from the gap between the socket 162 and the main body 17, thereby improving the mist discharge effect.

[0169] Method 2: The sleeve 162 and the liquid outlet 161 are designed as an integral structure. During the integral molding process of the sleeve 162 and the liquid outlet 161, the relative positions of the gas outlet 152 and the liquid outlet 111 can be more precisely controlled. For example, as shown in FIG35 , the sleeve 162 can be connected to at least one connecting strip 324 between the gas outlet 152 and the outer wall of the liquid outlet 161, so that the sleeve 162, the liquid outlet 161, and the connecting strip 324 form an integral structure.

[0170] Both of the above methods can quickly adjust the relative positions of the gas outlet 152 and the liquid outlet 111 to meet the ideal state, thereby ensuring that the mist discharge effect can be optimized.

[0171] Please refer to Figure 34 again. Optionally, the air outlet 152 is arranged around the periphery of the liquid outlet 111. Through such a design, there is gas with a relatively high flow rate around the liquid outlet 111, so that a uniform and stable low-pressure state is formed around the liquid outlet 111, ensuring that the essence in the liquid storage chamber 11 can be sprayed outward from the liquid outlet 111 in the form of mist, avoiding the spraying of both mist essence and liquid essence at the liquid outlet 111, and also solving the problem of intermittent spraying of essence at the liquid outlet 111, thereby improving the stability of the essence spraying at the liquid outlet 111. When the aforementioned method 1 is used to adjust the relative positions of the air outlet 152 and the liquid outlet 111, and when the adhesive layer 330 is not completely solidified, the adhesive layer 330 is actually used to adjust the concentricity of the air outlet 152 and the liquid outlet 111. To achieve a better misting effect, the concentricity of the air outlet 152 and the liquid outlet 111 is designed to be less than or equal to 0.1 mm. In this embodiment, the concentricity of the air outlet 152 and the liquid outlet 111 is set to 0.05 mm.

[0172] Referring to Figure 31 , the liquid storage chamber 11 includes a communicating liquid storage cavity 112 and a liquid outlet channel 113. The liquid storage cavity 112 preferably annularly surrounds the outer periphery of the liquid outlet channel 113. The liquid outlet port 111 on the liquid outlet member 161 is connected to the liquid outlet channel 113. The aperture of the liquid outlet channel 113 is 0.5 mm to 2 mm, and the aperture of the liquid outlet port 111 is 0.3 mm to 0.8 mm, with the aperture of the liquid outlet port 111 being smaller than the aperture of the liquid outlet channel 113. In this embodiment, the aperture of the liquid outlet port is 0.5 mm, and the aperture of the liquid outlet channel 113 is 1 mm. In another embodiment, the aperture of the liquid outlet port can be 0.3 mm, and the aperture of the liquid outlet channel 113 can be 0.5 mm. In yet another embodiment, the aperture of the liquid outlet port can be 0.8 mm, and the aperture of the liquid outlet channel 113 can be 2 mm. If the aperture of the liquid outlet channel 113 and the aperture of the liquid outlet port 111 are too small, it is not conducive to the outward misting. If the aperture of the liquid outlet channel 113 and the aperture of the liquid outlet port 111 are too large, the risk of leakage will be increased and the spray effect will be affected to a certain extent.

[0173] Referring again to Figure 31, the main body 17 is provided with a vent 116, which connects the liquid storage chamber 11 with the outside world, allowing the air pressure inside the liquid storage chamber 11 to balance with the outside air pressure. Specifically, as the liquid in the liquid storage chamber 11 gradually depletes, the air pressure inside the liquid storage chamber 11 decreases. At this time, outside air enters the liquid storage chamber 11 through the vent 116, ensuring that the air pressure inside the liquid storage chamber 11 increases to balance with the outside air pressure. This prevents the air pressure inside the liquid storage chamber 11 from being too low, preventing the liquid from being discharged outward. In other words, this ensures the stability and reliability of the liquid discharge. When liquid is replenished in the liquid storage chamber 11, the gas inside the liquid storage chamber 11 is discharged outward through the vent 116, preventing the air pressure inside the liquid storage chamber 11 from being too high after the liquid is replenished, which could cause abnormal liquid discharge. The diameter of the vent 116 is 0.5 mm to 1.5 mm. In this embodiment, the diameter of the air hole 116 is 1 mm; in another embodiment, the diameter of the air hole 116 can be 0.5 mm; and in yet another embodiment, the diameter of the air hole 116 can be 1.5 mm. If the diameter of the air hole 116 is too small, the air pressure in the liquid storage chamber 11 and the external air pressure will reach equilibrium more slowly. If the diameter of the air hole 116 is too large, the risk of leakage will increase.

[0174] Optionally, the air vent 116 can be designed in the top area as shown in Figure 31. Since the liquid in the liquid storage chamber 11 is located below the liquid storage chamber 11 due to its own gravity, as long as the height of the air vent 116 is higher than the liquid level, the risk of liquid leaking out of the air vent 116 can be reduced.

[0175] Please refer to Figures 32, 36, and 37. The main body 17 includes a first cylindrical surface 313, and the sleeve 162 includes a second cylindrical surface 3221. The first cylindrical surface 313 and the second cylindrical surface 3221 are mutually nested, and an adhesive layer 330 is connected between the first cylindrical surface 313 and the second cylindrical surface 3221. By providing the mutually nested first cylindrical surface 313 and the second cylindrical surface 3221, it is easier to adjust the position of the sleeve 162 relative to the liquid outlet 161, and in fact, it is easier to adjust the concentricity of the gas outlet 152 and the liquid outlet 111. Moreover, the matching method of the cylindrical surfaces also facilitates the spread of the adhesive layer 330 before it is completely solidified. This helps the adhesive layer 330 to seal the gap between the sleeve 162 and the main body 17, thereby ensuring that the gas in the third air supply channel 312 does not escape from the gap between the sleeve 162 and the main body 17, thereby improving the misting effect and stability.

[0176] Referring again to Figure 32 , the end surface of the main body 17, the inner wall of the sleeve 162, and the outer wall of the liquid outlet 161 collectively enclose an air outlet cavity 154. The third air supply channel 312, the air outlet cavity 154, and the air outlet 152 are sequentially connected. The provision of the air outlet cavity 154 ensures a sufficiently large flow rate of gas discharged from the air outlet 152 and makes the gas flow rate of the air outlet 152 surrounding the outer periphery of the liquid outlet 111 more uniform, further improving the stability of the spray from the liquid outlet 111. The adhesive layer 330 between the first cylindrical surface 313 and the second cylindrical surface 3221 effectively seals the air outlet cavity 154.

[0177] Please refer to Figures 32, 36 and 37 again. The main body 17 also includes a third cylindrical surface 314. The outer diameter of the third cylindrical surface 314 is not equal to the outer diameter of the first cylindrical surface 313, so that a first step surface 315 is connected between the first cylindrical surface 313 and the third cylindrical surface 314. Optionally, the outer diameter of the third cylindrical surface 314 is larger than the first cylindrical surface 313. Accordingly, the sleeve 162 includes a fourth cylindrical surface 3222, the outer diameter of which is unequal to that of the second cylindrical surface 3221. This allows a second stepped surface 223 to connect the second cylindrical surface 3221 and the fourth cylindrical surface 3222. The third cylindrical surface 314 and the fourth cylindrical surface 3222 are mutually engaged, and the first stepped surface 315 and the second stepped surface 223 are close to or in contact with each other. This design further seals the gap between the sleeve 162 and the main body 17, improving the sealing effect of the air outlet cavity 154. Furthermore, the range of fine-tuning the position of the sleeve 162 can be reduced, making it easier to adjust the concentricity of the air outlet 152 relative to the liquid outlet 111. In addition, when an adhesive layer 330 is bonded between the third cylindrical surface 314 and the fourth cylindrical surface 3222 , or / and when an adhesive layer 330 is bonded between the first step surface 315 and the second step surface 223 , the sealing effect of the air outlet cavity 154 can be further improved.

[0178] Please refer to Figures 32, 34, 36, and 37 again. In this embodiment, the sleeve 162 is preferably designed to be sleeved on the outer periphery of the main body 17. In other words, an open groove 224 is provided in the sleeve 162, and one end of the main body 17 is inserted into this groove 224. In fact, the end surface of the main body 17, the groove wall of the groove 224, and the outer wall of the liquid outlet member 161 together form the above-mentioned air outlet cavity 154. Under this design, the groove wall of the groove 224 includes the above-mentioned second cylindrical surface 3221, the second step surface 223, and the fourth cylindrical surface 3222. In addition, the outer diameter of the second cylindrical surface 3221 will be slightly larger than the outer diameter of the first cylindrical surface 313, and the outer diameter of the fourth cylindrical surface 3222 will be slightly larger than the outer diameter of the third cylindrical surface 314. In addition, the bottom of the groove 224 is provided with a through hole 225, and the liquid outlet member 161 is disposed within this through hole 225. The wall of the through hole 225 and the outer wall of the liquid outlet member 161 together constitute the aforementioned air outlet 152 surrounding the outer periphery of the liquid outlet 111. Referring to Figure 34, the minimum radial gap D1 between the sleeve 162 and the liquid outlet member 161 is 0.06mm-0.1mm. In fact, the minimum gap D1 is the minimum distance from the wall of the through hole 225 to the outer wall of the liquid outlet member 161. Through this design, the width of the air outlet 152 falls within an appropriate range, thereby achieving a better atomization effect. In this embodiment, the minimum gap D1 is 0.08mm; in another embodiment, the minimum gap D1 can be 0.06mm; and in yet another embodiment, the minimum gap D1 can be 0.1mm.

[0179] Please refer to Figures 28 and 14 together. This embodiment also provides a beauty instrument, which includes a main body 60 and an essence bottle 70. The essence bottle 70 includes the above-mentioned atomization chamber. When the essence bottle 70 only has the function of storing liquid and providing the liquid to be sprayed outward, the atomization chamber is the essence bottle 70. The essence bottle 70 is preferably detachably connected relative to the main body 60. By designing a detachable essence bottle 70, the user can replenish the essence by replacing the essence bottle 70, or the user can replenish the essence into the essence bottle 70 by himself. When replenishing the liquid into the essence bottle 70, the user does not need to hold the entire beauty instrument with a large volume, which makes it more convenient for the user to perform the liquid replenishment operation, thereby improving the user's usage experience. In this embodiment, the essence bottle 70 not only stores liquid and sprays it, but also integrates a microneedle device 2. The microneedle device 2 is connected to the main body 17. The microneedle device 2 can be a microneedle wafer or other microneedle form. A microneedle wafer can be understood as a wafer with multiple nanometer-scale microneedles. Each microneedle can stimulate the skin, opening up internal channels and allowing the user to better absorb the essence.
