Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to a hydrodermabrasion instrument. Background Art

[0002] With the development of society and the continuous improvement of the economic level, people are paying more and more attention to the maintenance of their own body shape and appearance on the premise of meeting their own health, and the beauty industry is also developing rapidly. A hydrodermabrasion instrument is one of the beauty instruments. The hydrodermabrasion instrument is an instrument that stimulates the human skin through micro-needles to form many fine channels in the skin in a short time, so that some essence liquids with active ingredients can penetrate into the skin, so as to achieve a beauty method for correcting skin defects, and can be used for local wrinkle removal, shaping, scar repair, etc. Specifically, the hydrodermabrasion instrument is provided with a micro-needle wafer. The micro-needle wafer can be understood as a wafer provided with a plurality of micro-needles at the nanometer level. When the micro-needles act on the human skin, the micro-needles can stimulate the human skin, thereby opening millions of channels in the skin epidermis with an area of several square millimeters without damaging the skin epidermis layer, so that the active ingredients of the essence liquid can effectively penetrate into the skin, achieving the stimulation of collagen proliferation and cell regeneration, and repairing aging cells, so as to achieve the beauty effect.

[0003] When the existing hydrodermabrasion instrument acts on the skin with micro-needles, the essence liquid is coated on the skin surface by squeezing or flowing out naturally, or the essence liquid is manually coated on the skin before using the hydrodermabrasion instrument, or the essence liquid is coated on the skin after the hydrodermabrasion instrument acts on the skin. For the way of coating the essence liquid, first, it is difficult to control the supply amount of the liquid, which is easy to cause waste due to too much supply; second, the coated essence liquid stays on the skin surface in a liquid state, and the active substance needs to overcome the surface tension of the liquid before penetrating into the skin, increasing the difficulty of absorbing the essence liquid; in addition, because the channels opened by the micro-needles in the cutin layer are very small, it is difficult for the large-molecule essence liquid coated on the skin to pass through quickly in large quantities, resulting in slow absorption and poor absorption effect of the essence liquid, and a large amount of the essence liquid stays on the skin surface, thus causing waste of the essence liquid. Moreover, after using the hydrodermabrasion instrument, in order to avoid the liquid staying on the skin surface from dripping and polluting the clothes, the user needs to spend time waiting, which affects the user experience.

[0058] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0059] Please refer to Figures 1 to 3 simultaneously. This embodiment discloses a hydrodermabrasion instrument, which includes a housing 1, a microneedle device 2, an atomization device 3 and a driving device 4.

[0060] Among them, the microneedle device 2 can be a microneedle wafer or other forms of microneedles. The microneedle wafer can be understood as a wafer provided with a plurality of nanoscale microneedles, and each microneedle can stimulate the human skin to open the internal channels of the skin.

[0061] In this embodiment, the microneedle device 2 and the atomization device 3 are installed on the housing 1, and the driving device 4 is installed on the housing 1 and is used to drive the microneedle device 2 to reciprocate in the first direction (i.e., the X-axis direction). 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 perform a reciprocating linear movement along the X-axis, so that the microneedle device 2 can automatically stimulate the skin, thereby optimizing the user experience. The microneedle device 2 slides in the positive direction of the X-axis to stimulate the human skin, and the microneedle device 2 slides in the reverse direction of the X-axis to reset. In addition, as Figure 3 shown, 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 skin beautifying instrument can be arranged along the X-axis, thereby reducing the spatial volume of the skin beautifying instrument in the radial direction, so that the user can easily hold and store it.

[0062] Please refer to Figures 1 to 3 together. The skin beautifying instrument further includes a mist outlet 121 communicating with the outside, and this mist outlet 121 is used for discharging the atomized essence generated by the atomization device 3 to the outside; the microneedle device 2 is provided with the mist outlet 121, and / or the mist outlet 121 is arranged close to the microneedle device 2. Specifically, as Figure 3 shown, the mist outlet 121 can be designed to surround the microneedle device 2 to be close to the microneedle device 2. The microneedle device 2 is provided with at least one through hole 21, and this hole 21 can also be used as the mist outlet 121. Of course, the mist outlet 121 can also be arranged side by side with and close to the microneedle device 2. It can be understood that the mist outlet 121 can be arranged only at a position close to the microneedle device 2, or the mist outlet 121 can be opened only on the microneedle device 2.

[0063] During the use of the hydrodermabrasion instrument of this solution, the driving device 4 can be used to drive the microneedle device 2 to slide reciprocally, enabling the microneedle device 2 to stimulate the human skin, thereby opening the internal channels of the skin. The atomizing device 3 atomizes the essence. The atomized small-molecule essence will be discharged outward from the mist outlet 121 and finally penetrate into the human skin, enabling the user to absorb the essence more quickly. Compared with the traditional methods of squeezing out or naturally flowing out the essence, this solution can supply the essence to the user in an atomized manner. First of all, the atomized method is easier to control the supply of the liquid and is not likely to cause waste. Secondly, the atomized essence can quickly enter the skin through the skin channels without having to overcome the surface tension of the liquid, making it easier to absorb the essence. Thirdly, the atomized essence has smaller molecules and is easier to enter the skin through the skin channels, with faster absorption and better effects, and there will be no excessive essence remaining on the skin, thus reducing the waste of the essence. Moreover, after the user finishes using it, there is no need to wait, thus saving the user's time and greatly improving the user experience. In addition, in this solution, the mist outlet 121 communicating with the outside is directly set on the microneedle device 2, or the mist outlet 121 is set near the microneedle device 2, or both positions are set at the same time. Therefore, the mist outlet 121 is close to the microneedle device 2. On the one hand, it can make the hydrodermabrasion instrument smaller in size for the user to hold and store. On the other hand, when the microneedle device 2 stimulates the human skin, the misty essence can quickly enter the skin in a timely manner, further improving the absorption effect of the essence. On the one hand, it can make more atomized essence spray onto the skin area where the microneedle device 2 acts, and can promote the penetration of the essence through microneedle enhanced permeability and reduce residues. On the other hand, it can make the atomized essence act on the same effective area on the skin as the microneedle device 2, thus greatly improving the skin care efficiency.

[0064] Please refer to again Figure 3 , the atomizing device 3 includes a mist outlet hole 33. The liquid essence is atomized and dispersed outward from this mist outlet hole 33. The mist outlet hole 33 is designed inside the microneedle device 2. There is a mist outlet channel 12 between the mist outlet hole 33 and the mist outlet 121. The misty essence sprayed from the mist outlet hole 33 will be discharged outward from the mist outlet 121 along the mist outlet channel 12 for the user to absorb. The mist outlet channel 12 can be directly formed by digging holes in the housing 1 or other components, or can be formed by stacking multiple components together and enclosing them. In this embodiment, the mist outlet hole 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 as to achieve the function that more atomized essence can be quickly sprayed onto the skin area where the microneedle device 2 acts to improve the absorption effect of the essence.

[0065] Please refer to Figure 21, there are five cases regarding the positional relationship among the microneedle device 2, the mist outlet 121, and the mist outlet hole 33. Among them, Case 1, Case 2, and Case 3 can all be understood as the mist outlet hole 33 being arranged inside the microneedle device 2, and Case 4 and Case 5 can both be understood as the mist outlet hole 33 being arranged outside the microneedle device 2 or being disposed on the same plane as the microneedle device 2. In this embodiment, Figure 3 The structure shown adopts the design of Case 2, that is, Figure 3 A mist outlet 121 is provided on the microneedle device 2. At the same time, a mist outlet 121 is also provided on the outer periphery of the microneedle device 2. Please refer to Figure 21 and Figure 22 . In Case 2, Case 3, and Case 5, multiple mist outlets 121 can be arranged on the outer periphery of the microneedle device 2. When the multiple mist outlets 121 on the outer periphery of the microneedle device 2 are all interconnected, it is similar to the structure shown in Figure 3 . Please refer to Figure 3 again. In the direction perpendicular to the first direction (i.e., the X-axis), the mist outlet 121 is arranged close to the microneedle device 2, and the distance range between the mist outlet 121 and the microneedle device 2 is 0 - 2 cm; or, as shown in Figure 22 , in the direction perpendicular to the first direction, multiple mist outlets 121 are arranged close to the microneedle device 2 and are spaced apart. In Case 4, the protruding mist outlet hole 33 is equivalent to the mist outlet 121.

[0066] Please refer to Figure 21 again. The mist outlet hole 33 in Case 1, Case 2, and Case 3 can be aligned with at least one mist outlet 121 (as shown in Case 1 or Case 2); or, as shown in Figure 19 , a mist guiding member 9 can be provided in the mist passage 12. The mist guiding member 9 is located between the microneedle device 2 and the atomizing device 3. The mist guiding member 9 is provided with a guiding passage 91, and the guiding passage 91 communicates the mist outlet hole 33 and the mist outlet 121 respectively to guide the misty essence to spray outwards from the mist outlet 121, reducing the diffusion of the misty essence, so as to guide more misty essence to the target skin. Among them, the mist guiding member 9 can be fixed to the housing 1 and does not vibrate with the microneedle device 2, or the mist guiding member 9 can also be designed to be relatively fixed to the microneedle device 2 to vibrate with the microneedle device 2.

[0067] Please refer to Figure 3 or Figure 21, in Case 1 to Case 5, the housing 1 further includes a nursing guide member 10 (as shown in Case 1, Case 3 and Case 5). The nursing guide member 10 is surrounded by a guiding space 101. The above-mentioned microneedle device 2 and the mist outlet 121 are both located in the guiding space 101, so that the misty essence sprayed from the mist outlet 33 can be sprayed onto the designated area of the human skin under the guidance of the guiding space 101. For example, when specifically using the hydrodermabrasion instrument, the nursing guide member 10 contacts the skin, and the misty essence can be precisely attached to the skin area covered by the nursing guide member 10 under the guidance of the guiding space 101, further reducing the waste caused by the dissipation of the atomized essence.

[0068] Please refer to again Figure 3 , the housing 1 further includes a liquid storage chamber 11 communicating with the mist outlet 33. The liquid storage chamber 11 is used to store the essence. The housing 1 further includes a mounting portion 822. The above-mentioned microneedle device 2 is fixed to the mounting portion 822, and the liquid storage chamber 11, 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). At this time, the driving device 4 drives the mounting portion 822 to reciprocate along the first direction to realize the function of the microneedle device 2 reciprocating 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 beneficial to reasonably utilize the internal space, realize the miniaturized design of the product, facilitate the user to hold and store, and at the same time is beneficial to setting the mist outlet 33 and the microneedle device 2 in the vicinity, thereby being beneficial to shortening the distance between the mist outlet 33 and the mist outlet 121, shortening the distance from the atomized essence to the mist outlet 121, reducing the condensation of the atomized essence in the mist passage 12, so as to increase the discharge amount of the atomized essence, and thus improve the absorption rate of the essence.

[0069] In order to achieve the purpose that the liquid storage chamber 11, the mounting portion 822 and the microneedle device 2 can be arranged in sequence along the first direction (i.e., the positive direction of the X-axis), this solution can design the atomizing device 3 as a structure with electric mist output or pneumatic mist output. For specific descriptions, please refer to the following two paragraphs:

[0070] Please refer to Figure 3 , the atomizing device 3 can be designed to include an atomizing sheet 31. The atomizing sheet 31 is arranged at the opening of the liquid storage chamber 11, and the atomizing sheet 31 has a mist outlet 33. Specifically, as Figure 3As shown in the figure, the atomizing sheet 31 can be disposed in the mist outlet channel 12 to block the opening of the liquid storage chamber 11, so as to prevent the liquid essence in the liquid storage chamber 11 from leaking outwards. At the same time, the interior of the atomizing sheet 31 has a pore structure, and the pore structure communicates the liquid storage chamber 11 with the outside world. In other words, this pore structure is equivalent to the above-mentioned mist outlet holes 33. When the atomizing sheet 31 is powered on, the atomizing sheet 31 vibrates, so that the molecular structure of the essence transported from the liquid storage chamber 11 to the atomizing sheet 31 is broken up to generate natural 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 outward leakage of the liquid essence in the liquid storage chamber 11. The structural design using the atomizing sheet 31 to atomize the essence is because the atomizing structure is simple and it is easier to achieve the purpose of arranging the liquid storage chamber 11, the mounting part 822 and the microneedle device 2 in sequence along the first direction (i.e., the positive X-axis direction). In addition, the atomizing sheet 31 is arranged between the liquid storage chamber 11 and the mounting part 822, so that the liquid storage chamber 11, the atomizing sheet 31, the mounting part 822 and the microneedle device 2 are arranged in sequence along the first direction (i.e., the positive X-axis direction), thereby making the body of the skin beautifying instrument smaller and more convenient for the user to hold and store. Specifically, the microneedle device 2 and the atomizing sheet 31 can both be disposed 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. The atomized essence generated by the mist outlet holes 33 can overflow from the periphery of the microneedle device 2 or overflow from the hole positions 21 opened on the microneedle device 2.

[0071] Please also 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 disposed close to the mist outlet holes 33 and communicates with the outside world. 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 holes 33 are arranged adjacent to each other, and the air flow output from the air outlet 152 causes a negative pressure to be formed near the air outlet 152 and the mist outlet holes 33. Because the air pressure at the mist outlet holes 33 is less than the air pressure in the liquid storage chamber 11, therefore, the essence in the liquid storage chamber 11 is discharged from the mist outlet holes 33 in a mist form along the mist outlet holes 33. The misty essence finally discharges outwards along the mist outlet channel 12 and penetrates into the human skin to achieve the absorption of the essence. By adopting the combined structure of the air pump 32 and the air outlet 152, the function of atomizing and discharging the essence can be realized, and the purpose of arranging the liquid storage chamber 11, the mounting part 822 and the microneedle device 2 in sequence along the first direction (i.e., the positive X-axis direction) can be achieved. In addition, by adopting the pneumatic mist discharging method, the particle size of the spraying liquid can be greatly reduced, the spraying efficiency can be improved, and the atomizing uniformity of the essence can be improved.

[0072] The following will explain the scheme of using the atomizing sheet 31 to discharge mist and the scheme of using the air pump 32 to discharge mist in more detail through two specific embodiments respectively.

[0073] Specific Embodiment 1: The atomizing device 3 employs an electric atomizing sheet 31.

[0074] Please refer to Figure 2 , this embodiment provides a hydrodermabrasion 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 inside 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 battery or a rechargeable battery, and the circuit board 6 can control the charging or discharging of the battery 5. During operation, the battery 5 can supply the required electrical energy for 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 atomizing efficiency or the vibration frequency of the microneedle device 2 along the X-axis. In addition, as Figure 3 shown, 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 hydrodermabrasion instrument can be arranged along the X-axis, thereby reducing the spatial volume of the hydrodermabrasion instrument in the radial direction, so that the user can easily hold the hydrodermabrasion instrument for beauty treatment.

[0075] In other embodiments, the hydrodermabrasion instrument can also be provided with a power cord, and the power cord is connected to the atomizing sheet 31 or the driving device 4, so that the atomizing sheet 31 or the driving device 4 can be not connected to the circuit board 6, and the atomizing sheet 31 or the driving device 4 can be directly connected to an external power source through the power cord. At this time, the atomizing sheet 31 or the driving device 4 can also be powered on and work.

[0076] In this embodiment, the atomizing sheet 31 does not reciprocate along the X-axis following the microneedle device 2. In other embodiments, the atomizing sheet 31 can also reciprocate along the X-axis together with the microneedle device 2. At this time, the atomizing sheet 31 can be connected to the circuit board 6 through a flexible wire to ensure that the atomizing sheet 31 can still maintain a reliable electrical connection relationship with the circuit board 6 when the atomizing sheet 31 reciprocates along the X-axis.

[0077] Please refer to again Figure 3 , a liquid guide rod 7 is arranged in the liquid storage chamber 11, the liquid guide rod 7 is in direct contact with the atomizing sheet 31, and the liquid guide rod 7 is used to guide the essence liquid in the liquid storage chamber 11 to the surface of the atomizing sheet 31, so as to improve the reliability that the atomizing sheet 31 can export and atomize the essence liquid in the liquid storage chamber 11. The use of the liquid guide rod 7 to transport the essence liquid has a stable rate, thereby improving the stability of the atomizing sheet 31 to produce mist.

[0078] Please refer to together Figures 3 to 6, the housing 1 of this embodiment includes a main housing 80 and a sub-housing 81 that are detachably connected. The above-mentioned mist outlet channel 12 can be arranged in the main housing 80 or in the sub-housing 81. Specifically, taking the case where the mist outlet channel 12 is arranged in the sub-housing 81 as an example for illustration: The sub-housing 81 includes a main body portion 17 and a mounting seat 82. The above-mentioned liquid storage chamber 11 and mist outlet channel 12 are both arranged in the main body portion 17. The above-mentioned atomization sheet 31 is fixed to the main body portion 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-housing 81 at the same time. When the sub-housing 81 is taken out, both the microneedle device 2 and the atomization sheet 31 will be separated from the main housing 80 together. By providing a detachable sub-housing 81, when the essence liquid in the liquid storage chamber 11 is used up, the user can replenish the essence liquid by replacing the sub-housing 81. On the one hand, it can improve the convenience of the user using the product. On the other hand, it can prevent the user from injecting other unknown liquids into the liquid storage chamber 11 by themselves, thereby preventing the user from absorbing unknown liquids when using the hydrodermabrasion instrument and improving the safety of the user using it. In this embodiment, the mounting seat 82 is slidably connected to the main body portion 17 in the first direction, and the above-mentioned driving device 4 is used to drive the mounting seat 82 to reciprocate in the first direction to realize the function of driving the microneedle device 2 to reciprocate in the first direction. Compared with directly driving the entire sub-housing 81 to move, the requirements for the driving device 4 are lower, thereby reducing the product cost; and by driving the mounting seat 82 to drive the microneedle device 2 to move, the electrical connection design of the atomization sheet 31 is simpler and the electrical connection will be more stable, which is more conducive to improving the stability of the product. In other embodiments, the mist outlet channel 12 can also be arranged in the mounting seat 82.

[0079] Specifically, based on the structure of the above-mentioned detachable sub-housing 81 designed, the sub-housing 81 can also include two first conductive members 83 arranged on the outer wall of the main body portion 17. One of the first conductive members 83 is connected to the positive electrode of the atomization sheet 31, and the other first conductive member 83 is connected to the negative electrode of the atomization sheet 31. Correspondingly, two second conductive members 13 are arranged on the inner wall of the main housing 80, and both of the two second conductive members 13 are electrically connected to the above-mentioned circuit board 6. When the sub-housing 81 is installed on the main housing 80, the main housing 80 and the sub-housing 81 are fixedly connected, and one of the second conductive members 13 contacts one of the first conductive members 83, and the other second conductive member 13 contacts the other first conductive member 83, so that when the sub-housing 81 is inserted into the main housing 80, the circuit board 6 can establish an electrical connection relationship with the atomization 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 atomization sheet 31. It can be understood that the contact manner between the second conductive member 13 and the first conductive member 83 can be elastic contact, and the elastic contact can improve the electrical connection stability between the second conductive member 13 and the first conductive member 83.

[0080] Among them, the way the auxiliary housing 81 and the main housing 80 are fixedly connected can be snap connection. Alternatively, an elastic shrapnel can be provided inside the main housing 80, and the outer wall of the auxiliary housing 81 is clamped by the shrapnel so that the auxiliary housing 81 can be relatively fixed to the main housing 80. The second conductive member 13 described above can be designed as the shrapnel here, so that the second conductive member 13 not only has the function of connecting the atomization sheet 31 and the circuit board 6, but also has the function of clamping and fixing the auxiliary housing 81. In other embodiments, the second conductive member 13 can be a conductive spring pin. At this time, the second conductive member 13 usually only functions to electrically connect the atomization sheet 31 and the circuit board 6.

[0081] In other embodiments, the second conductive member 13 may not be connected to the circuit board 6. The second conductive member 13 can be directly connected to an external power source through a power cord. At this time, the atomization sheet 31 can also be powered on and work.

[0082] More specifically, based on the structure with the detachable auxiliary housing 81 designed as above and the atomization sheet 31 inside the auxiliary housing 81 being fixed relative to the main housing 80 when the auxiliary housing 81 is installed in the main housing 80, the driving device 4 of this embodiment is specifically designed to include a driving component 41 and an elastic member 42. Among them, the driving component 41 is connected to the housing 1, and the driving component 41 is used to push the mounting seat 82 to move in the positive direction of the X-axis. The elastic member 42 is arranged between the mounting seat 82 and the main body portion 17. The elastic member 42 will apply a force to the mounting seat 82 in the opposite direction of the X-axis, so that the mounting seat 82 can move in the opposite direction of the X-axis for reset. Among them, the elastic member 42 can be a spring. By arranging the elastic member 42 inside the auxiliary housing 81, the function of the driving component 41 inside the hydrodermabrasion instrument only needs to be designed to push the micro-needle device 2 to move in the positive direction of the X-axis, without the need to design the function of pulling the micro-needle device 2 back, to meet the functional requirements that the auxiliary housing 81 needs to be detachable and the internal micro-needle device 2 can also perform reciprocating vibration, while simplifying the connection structure between the driving component 41 and the micro-needle device 2. In this embodiment, after the auxiliary housing 81 is installed on the main housing 80, the battery 5, the driving component 41, the atomization sheet 31, and the micro-needle device 2 are optionally arranged in sequence in the positive direction of the X-axis, so that the overall structure of the hydrodermabrasion instrument can be arranged along the X-axis, thereby reducing the spatial volume of the hydrodermabrasion instrument in the radial direction, so that the user can easily hold the hydrodermabrasion instrument for beauty treatment. It can be understood that the driving device 4 can be designed to only include the driving component 41, and the output shaft of the driving component 41 is connected to the auxiliary housing 81, so as to drive the auxiliary housing 81 to perform reciprocating motion in the first direction.

[0083] It can be understood that the sub-shell 81 is equivalent to an essence cartridge that integrates the liquid storage chamber 11, the microneedle device 2, the atomizing sheet 31, the mist outlet 121, the mist outlet channel 12, the mist outlet hole 33, the mounting seat 82, the elastic member 42 and the two first conductive members 83, wherein the main body 17 is equivalent to at least a part of the cartridge case of the essence cartridge. The remaining part of the water light instrument except the essence cartridge can be understood as the host, and the two second conductive members 13 are arranged on the host. When the essence cartridge is taken out, the two second conductive members 13 will be exposed on the host.

[0084] Please also read Figures 3 to 6 , Figures 7 to 10 The mounting seat 82 is designed to include a seat body 821, the above-mentioned mounting portion 822 and a guide portion 823 connected to the mounting portion 822, wherein the mounting portion 822 is used to fix the above-mentioned microneedle device 2, and the guide portion 823 encloses and forms an escape space 812, and the above-mentioned liquid storage chamber 11 is located in this escape space 812, and a guide groove 811 is provided on the periphery of the liquid storage chamber 11, and the guide portion 823 is slidably connected to the guide groove 811, and 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 the mounting seat 82, there are two ways to solve the problem of how the microneedle device 2 can be guided and slid in the first direction (i.e., the X-axis direction):

[0085] Method 1: Please refer to Figures 3 to 6, a plurality of guiding grooves 811 are provided on the outer periphery of the liquid storage chamber 11 of the main body portion 17. The guiding grooves 811 penetrate through the main body portion 17 in the X-axis direction. A plurality of guiding portions 823 that enclose to form an avoidance space 812 are provided. Each guiding portion 823 is inserted through a corresponding guiding groove 811 and connected to the seat body 821. When the auxiliary housing 81 is installed on the main housing 80, the seat body 821, the elastic member 42, the liquid storage chamber 11, the installation portion 822, and the microneedle device 2 are arranged in sequence along the positive direction of the X-axis. More specifically, the above-mentioned driving assembly 41 makes the guiding portion 823 and the microneedle device 2 able to approach the human skin along the positive direction of the X-axis by pushing the seat body 821 to move along the positive direction of the X-axis. One end of the elastic member 42 abuts against the main body portion 17, and the other end of the elastic member 42 abuts against the seat body 821. The elastic member 42 is used to apply an elastic force to the seat body 821 in the opposite direction of the X-axis, so that when the driving assembly 41 retracts along the opposite direction of the X-axis, the elastic member 42 can push the entire mounting seat 82 and the microneedle device 2 to move together along the opposite direction of the X-axis, thereby realizing the function of the microneedle device 2 vibrating reciprocally on the X-axis. With this structural design, the driving device 4 only needs to drive the mounting seat 82 to realize the driving of the microneedle device 2. The load of the driving device 4 is relatively light, which is beneficial to extending the service life of the driving device 4; in addition, the liquid storage chamber 11 is fixed relative to the main housing 80, eliminating the vibration caused by being driven by the driving device 4, which is beneficial to the stability and uniformity of liquid discharge. In addition, since the structure of the mounting seat 82 is adopted for the auxiliary housing 81, it will occupy more space in the X-axis direction. Therefore, the above two first conductive members 83 can be arranged on the outer surface in the radial direction of the main body portion 17 (that is, the outer peripheral surface parallel to the X-axis direction). It can be understood that the number of the guiding portions 823 and the guiding grooves 811 is not limited. Only one guiding portion 823 can also be provided, and correspondingly only one guiding groove 811 is also provided, as long as it can play a guiding role in the overall movement of the mounting seat 82. When only one guiding portion 823 and one guiding groove 811 are provided, the guiding portion 823 can be arranged in a flat shape, or at least arranged around part of the liquid storage chamber 11 (that is, the guiding portion 823 is a column with an arc-shaped cross-section in the direction perpendicular to the X-axis), so as to ensure the strength while realizing the simple structure of the guiding portion 823 and achieve stable guiding. It can be understood that when the driving device 4 is designed to only include the driving assembly 41, the output shaft of the driving assembly 41 is connected to the guiding portion 823 or connected to the guiding portion 823 by connecting the seat body 821, so as to drive the guiding portion 823 or the seat body 821 to move reciprocally in the first direction to drive the mounting seat 82 to move reciprocally in the first direction. The guiding portion 823 in this first method can be understood as a guide rod portion, and the guiding groove 811 in this first method is equivalent to a guiding hole extending in the first direction.

[0086] Method 2: Please refer to Figures 7 to 10, the main body 17 is provided with the above-mentioned liquid storage chamber 11, mist outlet 121 and guiding groove 811 at the same time. The guiding part 823 includes a first guiding part 826 and a second guiding part 825. The first guiding part 826 is sleeved on the outer peripheral side of the main body 17 so that the main body 17 is accommodated in the avoidance space 812 formed by it. The second guiding part 825 is connected to the mounting part 822 and passes through the guiding groove 811 to be connected to the first guiding part 826. At this time, the function that the mounting seat 82 can be slidably connected with the main body 17 in the X-axis direction is also realized. Based on the structural design of adopting this mounting seat 82, the above-mentioned elastic member 42 can be sleeved on the outer wall of the main body 17 and abutted between the first guiding part 826 and the main body 17. The elastic member 42 is compressed when the first guiding part 826 slides in the positive direction of the X-axis. That is, the elastic member 42 exerts an elastic force on the first guiding part 826 in the opposite direction of the X-axis. During actual operation, the above-mentioned driving assembly 41 can make the mounting seat 82 and the microneedle device 2 jointly approach the human skin in the positive direction of the X-axis by pushing the first guiding part 826 to move in the positive direction of the X-axis. When the driving assembly 41 retreats in the opposite direction of the X-axis, the elastic member 42 can push the entire mounting seat 82 and the microneedle device 2 to move jointly in the opposite direction of the X-axis, so as to realize the function that the microneedle device 2 makes a reciprocating vibration in the X-axis. In addition, since the auxiliary housing 81 adopts the structure of this mounting seat 82 and occupies more space in the radial direction, therefore, the above two first conductive members 83 can be arranged on the outer surface of the main body 17 in the X-axis direction (that is, the outer surface perpendicular to the X-axis direction). Similarly, it can be understood that when the driving device 4 is designed to only include the driving assembly 41, the output shaft of the driving assembly 41 can be connected to the first guiding part 826, so as to drive the mounting seat 82 to make a reciprocating motion in the first direction by driving the first guiding part 826 to make a reciprocating motion in the first direction.

[0087] In other embodiments, the above-mentioned driving device 4 can drive the entire auxiliary housing 81 integrated with the microneedle device 2, liquid storage chamber 11, and mist outlet 121 to make a reciprocating motion in the first direction, so as to realize the function that the microneedle device 2 makes a reciprocating motion in the first direction. At this time, it is also convenient to realize the purpose that the liquid storage chamber 11, mounting part 822, and microneedle device 2 are arranged in sequence in the first direction. However, if the atomizing sheet 31 is adopted in this scheme, since the liquid storage chamber 11 is integrated in the auxiliary housing 81, the atomizing sheet 31 needs to vibrate together with the auxiliary housing 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. Or, when the entire auxiliary housing 81 integrated with the microneedle device 2, liquid storage chamber 11, and mist outlet 121 makes a reciprocating motion in the first direction, the structure of using the atomizing sheet 31 to produce mist can also be not adopted, but the structure of pneumatic mist production can be adopted (see the specific embodiment two below for details).

[0088] Please refer to Figure 5, a buffer pad 84 can be provided on one end face of the mounting base 82 facing away from the microneedle device 2. Through the buffering of the buffer pad 84, the impact of the microneedle device 2 hitting the skin instantaneously can be reduced, so as to further improve the user experience. In addition, when the driving device 4 and the mounting base 82 are connected in a butting manner, during the process of the driving device 4 driving the mounting base 82 to move along the positive direction of the X-axis, the buffer pad 84 can play a protective role for the driving device 4.

[0089] Please refer to Figure 3 , Figure 11 and Figure 12 , the driving component 41 can be designed to include a motor 411, an eccentric wheel 412, a connecting rod 413 and a slider 414. Among them, the eccentric wheel 412 is connected to the output shaft of the motor 411, and 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 far 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. The slider 414 is limited in the housing 1, and the limitation of the housing 1 makes the slider 414 can only slide reciprocally along the X-axis. It can be understood that the first end of the connecting rod 413 can also be connected to the central 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.

[0090] During operation, the motor 411 drives the eccentric wheel 412 to rotate. 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 rotate universally relative to the eccentric wheel 412 and the slider 414 respectively. Therefore, the attitude of the connecting rod 413 will change under the drive of the eccentric wheel 412. Due to the change of the attitude of the connecting rod 413, 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 move reciprocally 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 outwards along the positive direction of the X-axis. The slider 414 moves the mounting base 82 along the positive direction of the X-axis, so that the microneedle device 2 fixedly connected to the mounting base 82 can move along the positive direction of the X-axis and stimulate the user's skin.

[0091] Please refer to again Figure 3 , Figure 11 and Figure 12A 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.

[0092] In this embodiment, the power for the mounting seat 82 to reset along the reverse direction of the X-axis comes from the elastic member 42, so the slider 414 of this embodiment reciprocates along the X-axis only to push the mounting seat 82 to move along the positive direction of the X-axis. In other embodiments, if the elastic member 42 is no longer provided, the slider 414 can be directly or indirectly connected to the mounting seat 82, so that the slider 414 is used to push the mounting seat 82 to move along the positive direction of the X-axis, and the slider 414 can also be used to pull the mounting seat 82 to retreat along the reverse direction of the X-axis, and the function of the microneedle device 2 to reciprocate along the X-axis can also be realized.

[0093] Please refer to the Figure 3 , Figure 11 and Figure 12, to achieve the function that the connecting rod 413 can rotate in all directions relative to the eccentric wheel 412 and the slider 414 respectively, the connecting rod 413 in this embodiment is designed to be in spherical contact with the eccentric wheel 412 and the slider 414 respectively. Specifically, a first spherical surface 4131 is provided at the first end of the connecting rod 413, and a concave first spherical surface groove 4121 is provided on the eccentric wheel 412. More than half of the first spherical surface 4131 is wrapped by the groove wall of the first spherical surface groove 4121, so that the eccentric wheel 412 can not only push the entire connecting rod 413 to move in the positive direction of the X-axis, but also pull the entire connecting rod 413 to move in the negative direction of the X-axis. Similarly, a second spherical surface 4132 is provided at the second end of the connecting rod 413, and a concave second spherical surface groove 4141 is provided on the slider 414. More than half of the second spherical surface 4132 is wrapped by the groove wall of the second spherical surface groove 4141, so that the connecting rod 413 can not only push the slider 414 to move in the positive direction of the X-axis, but also pull the slider 414 to move in the negative direction of the X-axis. It can be understood that the installation positions of the spherical surface groove and the spherical surface for realizing spherical contact can be interchanged, that is, spherical surface grooves are provided at both ends of the connecting rod 413, and spherical surfaces are provided on the eccentric wheel 412 and the slider 414, and the spherical contact between the connecting rod 413 and the eccentric wheel 412 and the slider 414 can also be realized, so as to realize the universal rotating connection. Because the contacts between the connecting rod 413 and the eccentric wheel 412 and the slider 414 are all spherical contacts, when the motor 411 drives the eccentric wheel 412 to rotate to drive the slider 414 to reciprocate, the connecting rod 413 and the eccentric wheel 412 and the slider 414 respectively generate rolling friction, thereby reducing the friction force between the connecting rod 413 and the eccentric wheel 412 and the slider 414 respectively, reducing noise and improving the driving stability.

[0094] Please refer to again Figure 3 、 Figure 11 and Figure 12 , in this embodiment, in order to reduce the difficulty of the first spherical surface groove 4121 that can wrap more than half of the first spherical surface 4131, the eccentric wheel 412 is designed to include two split-connected connecting blocks 4122, and the above-mentioned first spherical surface groove 4121 is jointly formed by the mutual splicing of the two connecting blocks 4122, and at least one of the two connecting blocks 4122 is connected to the output shaft of the above-mentioned motor 411. Similarly, the slider 414 is designed to include two split-connected splicing parts 4142, and the above-mentioned second spherical surface groove 4141 is jointly formed by the mutual splicing of the two splicing parts 4142, and at least one of the two splicing parts 4142 is limited in the housing 1 and can reciprocate relative to the housing 1 along the X-axis. When the splicing part 4142 slides in the positive direction of the X-axis, the splicing part 4142 is used to directly or indirectly push the mounting seat 82 and the microneedle device 2 to move in the positive direction of the X-axis.

[0095] Please refer to again Figure 11 andFigure 12 The motor 411, the eccentric wheel 412, the connecting rod 413 and the slider 414 are arranged in sequence along the positive direction of the X-axis, so that the driving assembly 41 can utilize the internal space of the hydrodermabrasion instrument along the X-axis direction and reduce the space in the radial direction of the hydrodermabrasion instrument, thereby facilitating the user to hold the hydrodermabrasion instrument more easily during the beauty process.

[0096] The above-mentioned driving device 4 can be used to drive other beauty function components except the micro-needle device 2. For example, the beauty function component 2 that is driven by the driving device 4 to vibrate can also be used for skin massage or for automatic makeup application to the skin, etc.

[0097] Specific Embodiment Two: The atomizing device 3 uses an air pump 32.

[0098] Please refer to Figures 13 to 15 This embodiment provides another hydrodermabrasion instrument, which includes a housing 1, a micro-needle device 2, an atomizing device 3, a driving device 4 and a circuit board 6. Among them, a liquid storage chamber 11 and a mist outlet channel 12 are also arranged in the housing 1. The micro-needle 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 micro-needle device 2 to reciprocate automatically along the X-axis. Different from Embodiment One, the atomizing device 3 of this Embodiment Two uses an air pump 32. The circuit board 6 is electrically connected to both the driving device 4 and the air pump 32, so that the circuit board 6 can provide the required electrical energy for the driving device 4 and the air pump 32 respectively.

[0099] Please refer to Figures 14 to 16 The atomizing device 3 of this specific Embodiment Two includes a mist outlet hole 33, an air outlet 152 and an air pump 32. An air outlet channel 15 is arranged in the housing 1, and a liquid outlet 111 is arranged in the liquid storage chamber 11. The liquid outlet 111 is communicated with the mist outlet channel 12, and this liquid outlet 111 is equivalent to the mist outlet hole 33 in the above-mentioned Specific Embodiment One; the air inlet 151 of the air outlet channel 15 is communicated with 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 hole 33. When the air pump 32 pumps gas into the air inlet 151 of the air outlet channel 15, 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 from the air outlet 152 causes a negative pressure at the air outlet 152, because the air pressure at the air outlet 152 is less than the air pressure in the liquid storage chamber 11, therefore, the essence liquid in the liquid storage chamber 11 is discharged outward in a mist form from the mist outlet hole 33, and the mist-like essence liquid finally discharges outward along the mist outlet channel 12 and penetrates into the human skin for the user to absorb the mist-like essence liquid.

[0100] Please refer to again Figure 16, the air outlet 152 of the air outlet passage 15 at least surrounds a part of the outer periphery of the mist outlet hole 33. In this embodiment, the mist outlet hole 33 is arranged inside the air outlet 152 of the air outlet passage 15, so that the air outlet 152 of the air outlet passage 15 completely surrounds the outer periphery of the mist outlet hole 33. Through such a design, there is a gas with a relatively high flow rate around the entire outer periphery of the mist outlet hole 33, thereby forming a uniform and stable low-pressure state around the mist outlet hole 33, ensuring that all the essence liquid in the liquid storage chamber 11 can be sprayed outwards in the form of mist from the mist outlet hole 33, avoiding the situation where both misty essence liquid and liquid essence liquid are sprayed out at the mist outlet hole 33, and at the same time solving the problem of intermittent spraying of the essence liquid at the mist outlet hole 33, improving the stability of the essence liquid spraying at the mist outlet hole 33.

[0101] Please refer to Figure 17 , the air outlet passage 15 can be specifically designed to include an air outlet main path 153, an air outlet cavity 154 and one or more air outlet branch paths 155. Here, taking the case where there are multiple air outlet branch paths 155 as an example for illustration, each air outlet branch path 155 connects the air outlet main path 153 and the air outlet cavity 154, and the air inlet 151 as described above is provided on the air outlet main path 153, and the air outlet 152 as described above is provided on the cavity wall of the air outlet cavity 154, that is, the air outlet 152, the air outlet cavity 154, the air outlet branch paths 155, and the air outlet main path 153 are connected in sequence. During operation, the gas pumped out by the air pump 32 will enter from the air inlet 151 through the air outlet main path 153 and be split into each air outlet branch path 155, and then the gas in each air outlet branch path 155 converges in the air outlet cavity 154 and finally flows outwards from the air outlet 152. Through such a design, the gas flow rate is large enough, and it can make the gas flow velocity of the air outlet 152 surrounding the outer periphery of the mist outlet hole 33 more uniform, so as to further improve the spraying stability of the mist outlet hole 33.

[0102] Please refer to again Figure 17 , based on the above structural design of the air outlet passage 15, the liquid storage chamber 11 can be designed to include a connected liquid storage cavity 112 and a liquid outlet passage 113. The above-mentioned mist outlet hole 33 is arranged at one end of the liquid outlet passage 113, the above-mentioned multiple air outlet branch paths 155 are jointly arranged around the outer periphery of the liquid outlet passage 113, and the liquid storage cavity 112 is in a ring structure, and the liquid storage cavity 112 is arranged in a ring around the outer periphery of the multiple air outlet branch paths 155. With this design of the liquid storage and gas supply structure, the layout of the liquid outlet passage 113 and the air outlet branch paths 155 corresponds to the layout of the liquid outlet 111 and the air outlet 152 respectively, making the conveying paths of the liquid and the gas linearly arranged and the paths the shortest, so that the mist spraying efficiency and the mist spraying stability can be increased.

[0103] Please refer to together Figures 15 to 18, the housing 1 of this embodiment specifically includes an atomizing nozzle 16 and a main body portion 17. Among them, the atomizing nozzle 16 is provided with the above-mentioned adjacent mist outlet holes 33 and air outlet 152. The atomizing nozzle 16 specifically includes a liquid outlet member 161 and a socket member 162. The socket member 162 is sleeved on the outer peripheral side of the liquid outlet member 161. The above-mentioned mist outlet holes 33 penetrate through the liquid outlet member 161. Moreover, a gap is provided between the socket member 162 and the liquid outlet member 161. It can be understood that there can be a gap between the entire outer circumference of the liquid outlet member 161 and the socket member 162. The liquid outlet member 161 can also be directly connected to the socket member 162, so that only a partial area of the outer circumference of the liquid outlet member 161 has a gap. This gap forms an air outlet cavity 154 between the socket member 162 and the liquid outlet member 161. The main body portion 17 is provided with an air supply channel 171 and the above-mentioned liquid storage chamber 11. The atomizing nozzle 16 is connected to the main body portion 17. The air outlet cavity 154 is communicated with the air supply channel 171. The air outlet 152 is formed at one end of the air outlet cavity 154 away from the air supply channel 171. This section of the 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.

[0104] Please refer to again Figures 15 to 18 , 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 portion 17 and 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 liquid in the liquid storage chamber 11 is used up, the user can detach the sub-housing 81 from the main housing 80 and replace it with a new sub-housing 81, which improves the convenience of product use and the user experience. In addition, the sub-housing 81 further includes a mounting seat 82 connected to the main body portion 17. The above-mentioned microneedle device 2 is fixed to this mounting seat 82. The main body portion 17, atomizing nozzle 16, mounting seat 82 and microneedle device 2 are arranged in sequence along the first direction (i.e., the X-axis direction). In other words, when the sub-housing 81 is detached from the main housing 80, the main body portion 17 with the liquid storage chamber 11, atomizing nozzle 16, mounting seat 82 and microneedle device 2 will all be separated from the main housing 80. The above-mentioned driving device 4 is also connected to the sub-housing 81. The driving device 4 is used to drive the entire sub-housing 81 to reciprocate along the X-axis, so as to enable the microneedle device 2 to reciprocate along the X-axis. The microneedle device 2 is integrated in the sub-housing 81 and is replaced along with the usage cycle of the sub-housing 81, ensuring the hygiene and safety of product use. In addition, the microneedle device 2 reciprocates along with the sub-housing 81, which can also simplify the overall structural design of the sub-housing 81.

[0105] As described above, the micro-needle device 2, the liquid storage chamber 11, the mist outlet channel 12, and the air supply channel 171 are integrated in the auxiliary housing 81 at the same time. The air supply channel 171 is communicated with the air outlet 152 through the air outlet cavity 154. Therefore, the air pump 32 only needs to introduce gas into the air supply channel 171 to jet air outward at the air outlet 152. Based on the structural design of the detachable auxiliary housing 81, please refer to Figure 14 and Figure 18 , the driving device 4 can be designed to include a connected driving mechanism 43 and a sliding seat 44. Among them, the driving mechanism 43 is arranged in the main housing 80, the sliding seat 44 is designed to be slidably connected with the main housing 80 in the X-axis direction, and the driving mechanism 43 is used to drive the sliding seat 44 to make a reciprocating linear movement along the X-axis direction. The auxiliary housing 81 is detachably connected to the sliding seat 44. When the auxiliary housing 81 is installed on the sliding seat 44, the auxiliary housing 81 and the sliding seat 44 are fixedly connected. When the driving mechanism 43 drives the sliding seat 44 to make a reciprocating linear movement, the entire auxiliary housing 81 will also follow the sliding seat 44 to make a reciprocating vibration along the X-axis, so as to realize the function of the micro-needle device 2 making a reciprocating vibration along the X-axis. In addition, a gas channel 441 is arranged in the sliding seat 44, and this gas channel 441 is communicated with the output port of the air pump 32. When the auxiliary housing 81 is installed on the sliding seat 44, the gas channel 441 will be communicated with the above-mentioned air supply channel 171. At this time, the air pump 32 only needs to pump gas into the gas channel 441 to make the gas pumped out by the air pump 32 spray out outward through the air supply channel 171 and the air outlet 152 in sequence. In addition, since the sliding seat 44 provided with the gas channel 441 makes a reciprocating vibration relative to the main housing 80 during operation, in order to ensure that the air pump 32 can stably and reliably pump gas into the gas channel 441, the gas channel 441 is connected to the output port of the air pump 32 through a soft air pipe 45.

[0106] Please refer to Figure 18 again, the driving mechanism 43 can be designed to include a motor 431, a cam 432, and a bearing 433. Among them, the motor 431 is fixed to the main housing 80, the cam 432 is fixedly connected to the output shaft of the motor 431, 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, and the sliding seat 44 is provided with a groove 442. The bearing 433 is embedded in the groove 442. When the motor 431 drives the cam 432 to make an eccentric rotation, the bearing 433 will also follow the cam 432 to make an eccentric rotation. The outer ring of the bearing 433 applies a thrust to the groove wall of the groove 442 so that the sliding seat 44 can make a reciprocating vibration relative to the main housing 80 on the X-axis. Among them, the bearing 433 can avoid the direct collision of the cam 432 with the groove wall of the groove 442, and can slow down 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 driving mechanism 43 driving the sliding seat 44 to make a reciprocating vibration.

[0107] In this embodiment, an elastic member 85 is provided between the mounting base 82 and the main body portion 17, or an elastic member 85 is provided between the mounting base 82 and the atomizing nozzle 16. Please refer to Figure 15 、 Figure 17 and Figure 18 . Taking the case where an elastic member 85 is provided between the mounting base 82 and the atomizing nozzle 16 as an example, the elastic member 85 can 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, so that when the driving device 4 drives the sub-housing 81 and the microneedle device 2 to move together along the positive X-axis direction and the microneedle device 2 acts on the human skin, the acting force of the microneedle device 2 on the human skin can be buffered, thereby improving the user experience.

[0108] Please refer to Figure 15 、 Figure 17 and Figure 18 again. The main body portion 17 includes a liquid core 172 and a housing 173. The liquid core 172 is provided with the above-mentioned liquid outlet channel 113, and the housing 173 is provided with the above-mentioned annular liquid storage cavity 112. The housing 173 is sleeved on the outer periphery of the liquid core 172 so that the liquid storage cavity 112 can surround the outer periphery of the liquid outlet channel 113. Through holes 174 for communicating the liquid storage cavity 112 and the liquid outlet channel 113 are provided in both the housing 173 and the liquid core 172, and the opening at one end of the liquid outlet channel 113 far from the through hole 174 forms the above-mentioned mist outlet hole 33. The design of this liquid storage structure is simple, easy to manufacture and process, and the liquid transportation path is short, so that the liquid outlet is smooth and the product stability is good. In addition, a first sealing member 18 is provided between the liquid core 172 and the housing 173 at the position of the through hole 174. The first sealing member 18 is used to prevent the essence liquid in the liquid storage cavity 112 and the liquid outlet channel 113 from overflowing outward. Specifically, the first sealing member 18 includes two sealing rings respectively sleeved on the outer peripheral side of the liquid core 172, and the two sealing rings are arranged at intervals. The through hole 174 communicating the liquid storage cavity 112 and the liquid outlet channel 113 is provided between the two sealing rings. It can be understood that the first sealing member 18 can also be arranged between the liquid core 172 and the housing 173 and sleeved on the outer periphery of the through hole 174. Specifically, a limiting groove surrounding the through hole 174 can be formed on the outer peripheral side wall of the liquid core 172 or the inner side wall of the housing 173, and the first sealing member 18 is arranged in the above-mentioned limiting groove and clamped by the liquid core 172 and the housing 173.

[0109] More specifically, please refer to Figure 15 、 Figure 17 and Figure 18, at one end of the liquid core 172 away from the mist outlet hole 33, the above-mentioned main air outlet path 153 is provided, and at the other end of the liquid core 172, one or more of the above-mentioned air outlet branch paths 155 are provided. A second seal 19 is provided between the liquid core 172 and the socket 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 liquid in the liquid outlet channel 113 or in the air outlet cavity 154 from overflowing outward. It can be understood that the main air outlet path 153 can be formed in the liquid core 172, can also be formed in the housing 173, or can be jointly formed by the liquid core 172 and the housing 173, which is not limited herein.

[0110] Please refer to Figure 19 and Figure 20, in addition to the above structure in which the liquid storage chamber 11 includes the liquid outlet channel 113 and the liquid storage cavity 112 surrounding the outer periphery of the liquid outlet channel 113, the liquid storage chamber 11 may also be a structure including a plurality of successively connected and communicated liquid storage channels 114. Among them, a liquid outlet hole 115 is provided at the end of the last liquid storage channel 114. Based on this structure of the liquid storage chamber 11, the main body portion 17 may be designed to include a liquid core 172, a third seal 175, and a fourth seal 176. Among them, the liquid core 172 is provided with the above-mentioned plurality of penetrating and successively connected and communicated liquid storage channels 114. The liquid core 172 is located between the third seal 175 and the fourth seal 176, so that both the third seal 175 and the fourth seal 176 can be used to limit the essence liquid in the liquid storage channel 114 from overflowing outward. The third seal 175 is provided with a liquid outlet flow channel 177. The liquid outlet flow channel 177 is communicated with the liquid outlet hole 115 of the last liquid storage channel 114. The liquid outlet flow channel 177 penetrates through the third seal 175. The above-mentioned mist outlet hole 33 is formed at one end of the liquid outlet flow channel 177 away from the liquid core 172. Specifically, the liquid outlet member 161 of the atomizing nozzle 16 is connected to the third seal 175, and the liquid outlet 111 penetrates through the liquid outlet member 161, so that the mist outlet hole 33 is communicated with one end of the liquid outlet flow channel 177 away from the liquid core 172. The flow path of the essence liquid can be summarized as follows: the essence liquid flows out from the liquid outlet hole 115 of the last liquid storage channel 114 and enters the liquid outlet flow channel 177, and then sprays out in a mist form from the mist outlet hole 33 after passing through the entire liquid outlet member 161. More specifically, one or more of the above-mentioned air outlet branches 155 may also be provided on the liquid core 172. The fourth seal 176 may be provided with the above-mentioned air outlet main path 153. The socket member 162 of the atomizing nozzle 16 may be connected to one end of the third seal 175 facing away from the liquid core 172. And the socket member 162 and the third seal 175 jointly enclose the above-mentioned air outlet cavity 154. The air outlet 152 is formed at one end of the air outlet cavity 154 away from the liquid core 172, thereby realizing the sequential communication of the air outlet 152, the air outlet cavity 154, the air outlet branch 155, and the air outlet main path 153. In addition, the liquid storage channel 114 is not directly communicated with any air outlet branch 155 inside the liquid core 172, so as to prevent the liquid essence liquid in the liquid storage channel 114 from flowing into the air outlet branch 155. The design of this liquid storage structure can make full use of the volume space of the liquid core 172 because of the plurality of successively connected and communicated liquid storage channels 114. Therefore, the liquid storage space can be increased without increasing the radial dimension, the frequency of the user replacing the sub-shell 81 can be reduced, and the user experience can be improved.

[0111] Please refer to Figure 15, to ensure a good fogging effect, the area ratio range of the fogging holes 33 to the air outlet 152 is 0.2 - 0.7, and / or, the distance between the fogging holes 33 and the air outlet 152 is greater than 0 mm but less than or equal to 0.5 mm. In this embodiment, optionally, the area ratio of the fogging holes 33 to the air outlet 152 can be set within the range of 0.2 - 0.7. For example, the area ratio of the fogging holes 33 to the air outlet 152 can be set to 0.2, 0.45, or 0.70. Optionally, the area ratio of the fogging holes 33 to the air outlet 152 can be set based on the required fogging amount. For example, when the required fogging amount is small, the area ratio of the fogging holes 33 to the air outlet 152 can be set to 0.2; when the required fogging amount is medium, the area ratio of the fogging holes 33 to the air outlet 152 can be set to 0.45; when the required fogging amount is large, the area ratio of the fogging holes 33 to the air outlet 152 can be set to 0.70.

[0112] Optionally, the distance between the fogging holes 33 and the air outlet 152 can be set within the range of greater than 0 mm and less than or equal to 0.5 mm. For example, the distance between the fogging holes 33 and the air outlet 152 can be 0.01 mm, 0.25 mm, or 0.5 mm. Optionally, the distance range between the fogging holes 33 and the air outlet 152 can be set based on the required fogging amount. For example, when the required fogging amount is large, the distance between the fogging holes 33 and the air outlet 152 can be set to 0.01 mm; when the required fogging amount is medium, the distance between the fogging holes 33 and the air outlet 152 can be set to 0.25 mm; when the required fogging amount is small, the distance between the fogging holes 33 and the air outlet 152 can be set to 0.5 mm.

[0113] Please refer to Figure 18 or Figure 19 , the chamber wall of the liquid storage chamber 11 is provided with a ventilation hole 116 communicating with the outside. By setting this ventilation hole 116, the air pressure in the liquid storage chamber 11 can always be equal to the external atmospheric pressure, solving the problem that it is difficult for the essence liquid to be output due to the too small air pressure in the liquid storage chamber 11 caused by the consumption of the essence liquid, that is, ensuring that all the essence liquid in the liquid storage chamber 11 can be stably and effectively output. To prevent the essence liquid in the liquid storage chamber 11 from leaking out along the ventilation hole 116, a waterproof and breathable component can be set at the ventilation hole 116. For example, the waterproof and breathable component can adopt a waterproof and breathable membrane in the battery field, and the waterproof and breathable membrane has the characteristic of isolating the inflow or outflow of liquid but allowing the free passage of internal and external gases.

[0114] In summary, the skin beautifying instrument of this embodiment can also supply the essence liquid to the user in an atomized manner, so that the user's skin will not stay with too much essence liquid during use, and thus can also reduce the waste of the essence liquid, and can also enable the user not to wait after use, thereby saving the user's time, and can also improve the absorption effect of the essence liquid.
