Description

Beauty Instruments Technical Field

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

[0002] The beauty device industry is currently experiencing unprecedented growth opportunities, with products gradually becoming part of people's daily lives. Hydrating devices, one of the many types of beauty devices, use microneedles to penetrate the skin at high speeds, opening up channels and allowing the active ingredients of serums to penetrate effectively. This stimulates collagen production and cell regeneration, repairing aging cells, and ultimately achieving a cosmetic effect.

[0003] Currently, when hyaluronic acid injections act on the skin through their microneedles, the essence is usually applied to the skin surface by squeezing or natural outflow. However, because the stratum corneum channels opened by the microneedles are very small, the essence molecules applied to the skin surface have difficulty passing through the skin channels, resulting in a large amount of essence remaining on the skin surface and poor absorption effect.

[0078] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the schemes in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments in this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0079] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0080] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0081] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0082] Based on the technical problem that existing water-light devices use extrusion or natural outflow to apply essence to the skin surface, resulting in poor absorption of the essence, this application proposes a beauty device for improving the absorption of essence during skin care. Optionally, the beauty device in this embodiment can be a water-light device.

[0083] 1 and 2 , the beauty device of this embodiment includes: a main housing 100; a sub-housing 200, which is detachably disposed on the main housing 100; a microneedle device 300, which is disposed on the sub-housing 200, and the microneedle device 300 includes microneedles 310 for acting on the skin; an atomizing device 400, at least a portion of which is disposed on the sub-housing 200, and the atomizing device 400 is used to generate a spray that acts on the skin; and a driving device 500, which is disposed on the main housing 100 and acts on the microneedle device 300 to drive the microneedles 310 to move.

[0084] The main housing 100 can have a variety of shapes, such as a roughly square, cylindrical, or spherical shape, while the auxiliary housing 200 can have a shape that matches the main housing 100, and the two can be combined to form a complete housing shape. For example, as shown in Figures 1 and 2, the auxiliary housing 200 is assembled with the main housing 100 to form a complete rectangular parallelepiped.

[0085] Among them, the microneedle device 300 is located in the auxiliary housing 200, and the microneedle 310 included in the microneedle device 300 can be a microneedle nanochip, which is like a micro needle head and can directly open the stratum corneum channel of the skin. The driving device 500 is located in the main housing 100. When the auxiliary housing 200 is assembled on the main housing 100, the driving device 500 is connected to the microneedle device 300. The microneedle device 300 can be driven by the driving device 500. Under the drive of the driving device 500, the microneedle 310 moves back and forth to continuously contact and detach from the skin, thereby opening the channel of the skin and facilitating the entry of substances such as beauty sprays and repair factors. Among them, the microneedle 310 cyclically performs an extension action and a retraction action during its reciprocating movement. The driving device 500 can be a one-way drive for extending the microneedle 310 or a one-way drive for retracting the microneedle 310. In this case, the output end of the driving device 500 is generally in abutment with the microneedle device 300. An elastic structure can be provided to cooperate with the driving device 500 to provide an elastic restoring force to the microneedle device 300, so that the microneedle 310 can perform a corresponding retraction or extension action. In addition, the driving device 500 can also be a two-way drive for both extending and retracting the microneedle 310. In this case, the output end of the driving device 500 is connected to the microneedle device 300. Under the drive of the driving device 500, the microneedle 310 performs a corresponding retraction or extension action. The structural composition of the driving device 500 can be various, which will be further described in the subsequent embodiments and will not be described in detail here. It is understandable that the microneedle device 300 can be driven by the driving device 500, including the driving device 500 directly driving the microneedle device 300 to move back and forth, and also including the driving device 500 indirectly driving the microneedle device 300 to move back and forth when the driving device 500 is indirectly connected to the microneedle device 300.

[0086] In addition, the atomizing device 400 is at least partially located in the auxiliary housing 200. Alternatively, the atomizing device 400 may be partially located in the auxiliary housing 200. In this structural arrangement, the other portion of the atomizing device 400 may be located on the main housing 100. When the auxiliary housing 200 is assembled to the main housing 100, the two portions of the atomizing device 400 may be connected for use. Alternatively, the atomizing device 400 may be entirely located in the auxiliary housing 200. The structural composition of the atomizing device 400 can be set according to actual conditions. For example, the atomizing device 400 may use an atomizing nozzle 410 or an atomizing sheet.

[0087] Furthermore, the beauty instrument may also include a control circuit board (not shown), and the atomization device 400 and the driving device 500 are both electrically connected to the main control circuit board. The main control circuit board is used to control the operation of the atomization device 400 and / or the driving device 500 according to the control instructions issued by the user through operation buttons or touch screen or remote wireless.

[0088] It is easy to understand that the main housing 100, the driving device 500 and the like are combined to form the main unit of the beauty instrument. The sub-housing 200 and at least part of the structure of the microneedle device 300 and the atomizing device 400 are combined to form the beauty atomizing cartridge. The beauty atomizing cartridge is detachable from the main unit for easy routine maintenance or replacement. The beauty atomizing cartridge can be a disposable beauty atomizing cartridge or a reusable beauty atomizing cartridge, without limitation. In the accompanying drawings, Figures 1 to 6, 7 to 12, and 13 to 15 respectively show three types of beauty instruments with different beauty atomizing cartridges.

[0089] When the beauty instrument of this embodiment is in use, the driving device 500 acts on the microneedle device 300, driving the microneedles 310 to move to open the skin channels. At the same time, the spray generated by the atomizing device 400 is sprayed onto the skin surface, enters the skin through the skin channels and is absorbed, thereby achieving a beauty effect.

[0090] The beauty device of the present application generates a spray that acts on the skin through the atomizing device 400. When sprayed onto the skin surface, the tiny spray particles are more easily passed through the tiny skin channels, quickly entering the skin and being absorbed, resulting in a fast absorption rate and good absorption effect. In addition, the spray method makes it easier to control the amount of liquid discharged, which can reduce the amount of beauty liquid left on the skin surface, thereby reducing waste.

[0091] In some embodiments, referring to FIG. 3 to FIG. 6 , the auxiliary housing 200 has a liquid storage chamber C, and the atomizing device 400 includes:

[0092] The atomizing nozzle 410 is provided in the auxiliary housing 200. The atomizing nozzle 410 has a liquid passage 410a. One end of the liquid passage 410a is connected to the liquid storage chamber C, and the other end is provided with a mist outlet 410b.

[0093] The liquid-displacing mechanism 420 is used to drive the cosmetic liquid in the liquid storage chamber C into the liquid passage 410a.

[0094] During operation, the atomizing device 400 of this embodiment is driven by the liquid-discharging mechanism 420, so that the beauty liquid in the liquid storage chamber C is transported to the liquid-discharging channel 410a. The beauty liquid flows along the liquid-discharging channel 410a to the mist outlet 410b, where it forms a beauty spray and is ejected outwardly. Optionally, the atomizing nozzle 410 is a straight-through atomizing nozzle 410, and the inner diameter of the liquid-discharging channel 410a is configured to gradually decrease along the direction of the beauty liquid flow. After being driven by the liquid-discharging mechanism 420, the beauty liquid acquires significant kinetic energy. During flow, the inner wall of the liquid-discharging channel 410a squeezes the beauty liquid, and after passing through the smaller atomizing holes, it is ejected at a high velocity. Due to the interaction of the liquid's surface tension, viscosity, and inner wall resistance, the liquid gradually transforms from a smooth and wavy flow to a spray flow, forming a beauty spray at the mist outlet 410b and ejecting it outwardly, achieving rapid mist output.

[0095] The liquid-displacing mechanism 420 can adopt a variety of structural configurations. As an example, the liquid-displacing mechanism 420 may include a micropump, with the liquid passage 410a connected to the liquid storage chamber C via a liquid delivery pipeline, and the micropump disposed on the liquid delivery pipeline. In this manner, the micropump can be controlled to pump the beauty liquid in the liquid storage chamber C along the liquid delivery pipeline to the liquid passage 410a of the atomizing nozzle 410. In addition to this example, the liquid-displacing mechanism 420 can also adopt other structural configurations, which will be further described in subsequent embodiments and are not limited to this embodiment. In addition, the atomizing device 400 mentioned in the aforementioned embodiment may be partially disposed on the auxiliary housing 200, the liquid-displacing mechanism 420 may be disposed on the main housing 100, and the atomizing nozzle 410 may be disposed on the auxiliary housing 200. When the auxiliary housing 200 is assembled to the main housing 100, the liquid-displacing mechanism 420 and the atomizing nozzle 410 are correspondingly connected to each other by a driving force, so that the liquid-displacing mechanism 420 can drive the beauty liquid in the liquid storage chamber C to be transported to the liquid passage 410a of the atomizing nozzle 410. Alternatively, the atomizing device 400 mentioned in the aforementioned embodiment may be entirely disposed on the auxiliary housing 200, and the liquid-displacing mechanism 420 and the atomizing nozzle 410 are disposed together on the auxiliary housing 200, that is, on the auxiliary housing 200, the liquid-displacing mechanism 420 and the atomizing nozzle 410 are connected by a driving force.

[0096] In some embodiments, referring to FIG3 , the liquid displacement mechanism 420 includes:

[0097] The air pressure regulating assembly 421 is provided on the main housing 100. The air pressure regulating assembly 421 has an air supply port 421a for connecting to the mist outlet hole 410b. The air pressure regulating assembly 421 changes the air pressure at the mist outlet hole 410b. An air pressure difference is formed between the air pressure at the mist outlet hole 410b and the air pressure in the liquid storage chamber C. The beauty liquid in the liquid storage chamber C is transported to the liquid passage 410a under the action of the air pressure difference.

[0098] The liquid-displacing mechanism 420 of this embodiment is a high-pressure liquid-displacing mechanism 420. When the auxiliary housing 200 is assembled with the main housing 100, the air supply port 421a of the air pressure regulating assembly 421 of the liquid-displacing mechanism 420 communicates with the mist outlet 410b of the atomizing nozzle 410. By controlling the operation of the air pressure regulating assembly 421, the air pressure at the mist outlet 410b is varied, thereby creating a pressure differential between the air pressure at the mist outlet 410b and the air pressure in the liquid storage chamber C. This pressure differential imparts greater kinetic energy to the beauty liquid in the liquid storage chamber C, allowing it to flow from the liquid storage chamber C into the liquid passage 410a of the atomizing nozzle 410. Specifically, when the air pressure regulating assembly 421 is in operation, the air supply port 421a outputs a high-speed airflow, and the high-speed airflow is ejected from the mist outlet 410b in the mist outlet direction, thereby forming a negative pressure at the mist outlet 410b. Because the air pressure at the mist outlet 410b is lower than the air pressure in the liquid storage chamber C, the beauty liquid in the liquid storage chamber C flows into the liquid passage 410a.

[0099] Optionally, the air pressure regulating assembly 421 includes an air pump, the exhaust port of the air pump is the air supply port 421a, and the exhaust port of the air pump is exposed on the surface of the main housing 100. Depending on the structure of the atomizing nozzle 410, it can be as shown in FIG3, after the auxiliary housing 200 is assembled with the main housing 100, the exhaust port of the air pump is connected to the atomizing nozzle 410 through a flexible pipe; or it can be as shown in FIG9 and FIG13, after the auxiliary housing 200 is assembled with the main housing 100, the exhaust port of the air pump is automatically connected to the atomizing nozzle 410.

[0100] Among them, the air supply port 421a of the air pressure regulating component 421 is connected to the mist outlet hole 410b of the atomizing nozzle 410. There are many structural settings. As an example, the outer peripheral side of the mist outlet hole 410b of the atomizing nozzle 410 is provided with an outlet flow channel, and the air supply port 421a of the air pressure regulating component 421 is connected to the outlet flow channel to form a connection with the mist outlet hole 410b of the atomizing nozzle 410. Optionally, the outlet flow channel can be formed by an outlet pipe, and the outlet pipe is provided on the side of the atomizing nozzle 410, including but not limited to this.

[0101] In some embodiments, referring to FIG5 , FIG6 , FIG13 and FIG14 , the atomizing nozzle 410 includes a cover shell 411 and an inner shell 412 , wherein the cover shell 411 covers the inner shell 412 , and a gap is provided between at least a portion of the cover shell 411 and at least a portion of the inner shell 412 ;

[0102] The inner shell 412 is formed with a liquid passage 410a, the gap between the cover shell 411 and the inner shell 412 forms an air passage 410c, and the end of the air passage 410c close to the mist outlet 410b forms an air outlet 410d; alternatively, the inner shell 412 is formed with an air passage 410c, the gap between the cover shell 411 and the inner shell 412 forms the liquid passage 410a, and the end of the air passage 410c close to the mist outlet 410b forms an air outlet 410d;

[0103] The air supply port 421a is connected to the mist outlet 410b through the air passage 410c and the air outlet 410d.

[0104] In this embodiment, the atomizing nozzle 410 adopts a structural structure of a cover shell 411 and an inner shell 412, with the inner shell 412 inside and the cover shell 411 outside and covered by the inner shell 412. Specifically, the inner shell 412 itself is formed with a channel, and a gap is provided between at least a partial area of ​​the cover shell 411 and a partial area of ​​the inner shell 412. According to the front view angle of the atomizing nozzle 410, the channel is inside and the gap is outside. Among them, the cover shell 411 and the inner shell 412 are integrally formed, or the cover shell 411 and the inner shell 412 are detachably connected, which is set according to actual conditions. The shape structure of the cover shell 411 and the inner shell 412 can adopt a variety of shapes, for example, the inner shell 412 is conical and the cover shell 411 is cylindrical; or, the inner shell 412 and the cover shell 411 are both conical.

[0105] Based on the included cover shell 411 and inner shell 412, the atomizing nozzle 410 of this embodiment can include the following two types:

[0106] The first type, as shown in Figures 5 and 6, is that the channel formed by the inner shell 412 is a liquid channel 410a, and the gap between the cover shell 411 and the inner shell 412 forms an air channel 410c, and the air channel 410c forms an air outlet 410d near one end of the mist outlet 410b. That is, from the front view of the atomizing nozzle 410, the liquid channel 410a is inside, the air channel 410c is outside, and the mist outlet 410b is located in the area of ​​the air outlet 410d. When the air pressure regulating component 421 is working, the air supply port 421a outputs a high-speed airflow, and the high-speed airflow flows through the air channel 410c and is ejected to the external environment through the air outlet 410d to form a negative pressure at the mist outlet 410b located in the area of ​​the air outlet 410d.

[0107] The second type, as shown in Figures 13 and 14, is that the gap between the cover shell 411 and the inner shell 412 forms a liquid passage 410a, and the channel formed by the inner shell 412 is an air passage 410c, and the air passage 410c forms an air outlet 410d at one end close to the mist outlet 410b. That is, from the front view of the atomizing nozzle 410, the air passage 410c is inside, the liquid passage 410a is outside, and the mist outlet 410b is located in the area of ​​the air outlet 410d. When the air pressure regulating component 421 is working, the air supply port 421a outputs a high-speed airflow, which flows through the air channel 410c and is ejected to the external environment through the air outlet 410d to form a negative pressure at the mist outlet 410b outside the area of ​​the air outlet 410d. Optionally, the inner shell 412 is positioned on the bottom wall of the liquid storage chamber C and is integrally formed with the secondary housing 200. A channel formed by the inner shell 412 extends through the bottom wall of the liquid storage chamber C and can be connected to the air supply port 421a. The cover 411 covers the inner shell 412, with a gap formed between the bottom of the cover 411 and the bottom wall of the liquid storage chamber C. Optionally, the gap is annular. This gap forms the inlet 410e of the liquid passage 410a, through which the beauty liquid in the liquid storage chamber C can enter the liquid passage 410a.

[0108] In this embodiment, the atomizing nozzle 410 can be configured in any of the two aforementioned structural configurations, and can be configured according to actual conditions without limitation.

[0109] When the atomizing nozzle 410 adopts the first type of atomizing nozzle 410 described above, its structure may be further configured, for example:

[0110] In some embodiments, referring to Figures 5 and 6 , when the gap between the housing 411 and the inner shell 412 forms an air passage 410c, the air passage 410c surrounds the outer peripheral wall of the liquid passage 410a to form a buffer chamber H. The housing 411 further includes an inlet flow channel 411a. The air supply port 421a communicates with the buffer chamber H through the inlet flow channel 411a, and the buffer chamber H communicates with the air outlet 410d. When the air pressure regulating assembly 421 is in operation, the high-speed airflow output from the air supply port 421a flows through the inlet flow channel 411a into the buffer chamber H, then flows through the buffer chamber H to the air outlet 410d, and is ejected through the air outlet 410d. Optionally, the air intake direction of the inlet flow channel 411a is perpendicular to the air outlet direction of the air outlet 410d. Among them, the buffer chamber H is formed by the air passage 410c surrounding the outer peripheral side of the inner shell 412, which can evenly disperse the high-speed airflow entering from the inlet air passage 411a and guide it to be sprayed out at the air outlet 410d, so as to achieve uniform air outlet from the air outlet 410d, thereby enhancing the negative pressure effect at the mist outlet 410b, and achieving a better mist outlet effect.

[0111] In some embodiments, referring to Figure 6 , one end of the liquid passage 410a, which is provided with a mist outlet 410b, is located within the air outlet 410d. Specifically, the air outlet 410d is arranged around the mist outlet 410b. When the air pressure regulating assembly 421 is in operation, the air outlet 410d circumferentially discharges air around the mist outlet 410b, resulting in uniform air discharge and a good negative pressure effect, thereby improving the misting effect.

[0112] Alternatively, in some embodiments, one end of the liquid passage 410a, provided with the mist outlet hole 410b, protrudes from the air outlet hole 410d. Specifically, when the high-speed airflow is emitted from the air outlet hole 410d, a negative pressure zone is formed at the location of the air outlet hole 410d. Due to inertia, a certain distance exists between the negative pressure zone and the air outlet hole 410d. Therefore, the mist outlet hole 410b is protruded from the air outlet hole 410d, closer to the negative pressure zone, and thus facilitates mist discharge.

[0113] In some embodiments, the area ratio of the mist outlet hole 410b to the air outlet hole 410d is 20% to 70%; and / or the distance between the air outlet hole 410d and the mist outlet hole 410b is greater than 0 mm and less than or equal to 0.5 mm.

[0114] In this embodiment, optionally, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set within the range of 20% to 70%. For example, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set to 20%, 45% or 70%. Optionally, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set based on the required mist output. For example, when the required mist output is small, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set to 20%; when the required mist output is medium, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set to 45%; when the required mist output is large, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set to 70%.

[0115] Optionally, the distance between the air outlet hole 410d and the mist outlet hole 410b 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 air outlet hole 410d and the mist outlet hole 410b can be 0.01 mm, 0.25 mm, or 0.5 mm. Optionally, the distance range between the air outlet hole 410d and the mist outlet hole 410b can be set based on the required mist output. For example, when the required mist output is large, the distance between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.01 mm; when the required mist output is medium, the distance between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.25 mm; when the required mist output is small, the distance between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.5 mm.

[0116] In some embodiments, referring to Figures 3, 5, 9 and 10, the auxiliary shell 200 is provided with a liquid guiding member 220 located in the liquid storage chamber C, and the liquid guiding member 220 is provided with a liquid guiding channel 220a, one end of the liquid guiding channel 220a is connected to the liquid passage 410a, and the other end extends toward the bottom wall of the liquid storage chamber C and is connected to the liquid storage chamber C.

[0117] In this embodiment, the liquid guide member 220 may include a liquid guide tube, within which a liquid guide channel 220a is formed. Optionally, the liquid guide tube is in an inverted L-shape, with the upper end of the liquid guide tube laterally connected to the atomizing nozzle 410, and the lower end of the liquid guide tube extending vertically toward the bottom wall of the liquid storage chamber C. When the air pressure regulating assembly 421 is in operation, a pressure difference is formed between the air pressure at the mist outlet 410b and the air pressure in the liquid storage chamber C. Under the action of this pressure difference, the beauty liquid in the liquid storage chamber C flows along the liquid guide channel 220a of the liquid guide member 220 to be transported to the liquid flow channel 410a of the atomizing nozzle 410. The spacing between the other end of the liquid guide channel 220a and the bottom wall of the liquid storage chamber C can be set sufficiently small, such as 0.1 mm. In this way, the beauty liquid in the liquid storage chamber C can be fully used, the residual amount of beauty liquid can be reduced, and the utilization rate of the beauty liquid can be improved.

[0118] In the beauty instrument of the present application, the liquid storage chamber C on the secondary housing 200 can be arranged in various forms, such as:

[0119] In some embodiments, referring to Figures 3 to 5, the sub-shell 200 is provided with a liquid storage box 210, and the liquid storage box 210 is constructed with a liquid storage chamber C and a mounting chamber Z connected to the liquid storage chamber C. The atomizing nozzle 410 is installed in the mounting chamber Z, and the liquid storage box 210 is provided with a first mist outlet 211 connected to the mounting chamber Z. The spray sprayed from the mist outlet 410b is dispersed to the external space through the first mist outlet 211.

[0120] In this embodiment, the liquid storage chamber C is formed by the liquid storage box 210 provided on the auxiliary shell 200, and the liquid storage box 210 is further configured with an installation chamber Z. The cavity shape of the installation chamber Z is adapted to the outer contour of the atomizing nozzle 410. The atomizing nozzle 410 is installed in the installation chamber Z, and the mist outlet 410b faces the first mist outlet 211. When the mist outlet 410b of the atomizing nozzle 410 sprays the beauty spray, the beauty spray is correspondingly dispersed to the external space through the first mist outlet 211 of the liquid storage box 210. Among them, the atomizing nozzle 410 of this embodiment can be combined with the liquid guide 220 of the aforementioned embodiment. In the liquid storage box 210, the atomizing nozzle 410 is connected to the liquid guide 220, and the liquid guide 220 is located in the liquid storage chamber C and extends toward the bottom wall of the liquid storage chamber C. Optionally, an air intake pipe forming an air intake channel 411 a is protruded from the outer wall of the shell, and the air intake pipe is provided through the liquid storage box 210 to be connected to the air supply port 421 a of the air pressure regulating component 421 .

[0121] Optionally, the liquid storage box 210 is detachably mounted on the secondary housing 200. The form of detachable mounting can be selected based on actual circumstances and is not limited in this embodiment. In practical applications, the liquid storage box 210 can be disposable. When the beauty liquid in the old liquid storage box 210 on the secondary housing 200 is used up, a new liquid storage box 210 can be replaced.

[0123] The microneedles 310 are mounted on one end of the liquid storage box 210 where the first mist outlet 211 is provided. The driving device 500 acts on the liquid storage box 210 to drive the liquid storage box 210 to slide and thereby drive the microneedles 310 to move.

[0124] In this embodiment, a sliding cavity D is provided through both sides of the secondary housing 200. The shape of the sliding cavity D matches the outer contour of the liquid reservoir 210. The liquid reservoir 210 is mounted in the sliding cavity D and can slide along the sliding cavity D. The liquid reservoir 210 serves as an intermediate transmission member, connecting the drive device 500 and the microneedle device 300 and transmitting power between the drive device 500 and the microneedles 310. Specifically, when the secondary housing 200 is assembled to the main housing 100, the driving end of the drive device 500 is docked with the liquid reservoir 210. When the drive device 500 is in operation, the driving end of the drive device 500 drives the liquid reservoir 210 to slide within the sliding cavity D, causing the microneedles 310 on the liquid reservoir 210 to move with the liquid reservoir 210. The connection between the driving end of the drive device 500 and the liquid reservoir 210 can be achieved by a snap-fit ​​connection, a magnetic connection, or the like, without limitation. Optionally, the microneedle 310 can be arranged adjacent to the first mist outlet 211, and the microneedle 310 and the beauty spray act on different areas of the skin at the same time.

Furthermore, the number of sets of limiting grooves 30 and limiting protrusions 40 may be one or more, depending on the actual situation.

[0149] In some embodiments, referring to Figures 2 and 8, the main shell 100 includes a first side wall 101 and a second side wall 102 forming a mounting position, the output end of the driving device 500 is exposed to the first side wall 101 and is connected to the microneedle device 300, and the air supply port 421a of the air pressure regulating assembly 421 is exposed to the second side wall 102 and is connected to the atomizing nozzle 410.

[0150] In this embodiment, the first side wall 101 and the second side wall 102 of the main housing 100 are perpendicular to each other, forming an L-shaped mounting position. When the auxiliary housing 200 is assembled with the main housing 100, one side surface of the auxiliary housing 200 is aligned with the first side wall 101, and the bottom surface of the auxiliary housing 200 is aligned with the second side wall 102. When the auxiliary housing 200 is assembled with the main housing 100, the microneedle device 300 on the auxiliary housing 200 forms a driving connection with the output end of the driving device 500 exposed by the first side wall 101, and the air supply port 421a of the air pressure regulating assembly 421 exposed by the second side wall 102 can be connected to the atomizing nozzle 410 on the auxiliary housing 200.

[0151] In combination with the above embodiment, the first side wall 101 may be provided with two limiting grooves 30, which are arranged opposite each other, and the auxiliary housing 200 is provided with limiting protrusions 40 on both sides, which extend along the length of the auxiliary housing 200. During assembly, the auxiliary housing 200 can be inserted into the main housing 100 along the length direction, and the limiting protrusions 40 on both sides of the auxiliary housing 200 are correspondingly inserted into the two limiting grooves 30 on the first side wall 101, thereby allowing the auxiliary housing 200 to be installed at the installation position of the main housing 100.

[0152] In some embodiments, referring to Figures 3, 9, and 16 to 19, the driving device 500 includes a push rod 510, a motor 520, and a transmission wheel 530. The transmission wheel 530 is provided on the output shaft of the motor 520 and is in transmission connection with the push rod 510. The motor 520 drives the transmission wheel 530 to drive the push rod 510, providing a force to the microneedle 310 to move it.

[0153] When the secondary housing 200 is mounted on the main housing 100, the push rod 510 of the drive device 500 docks with the microneedle device 300. When the beauty device is in operation and the drive device 500 is activated, the motor 520 drives the transmission wheel 530 to rotate, thereby driving the push rod 510 to move. The push rod 510 correspondingly pushes the microneedle device 300 to move the microneedles 310. In conjunction with the aforementioned embodiment, the microneedle device 300 includes a transmission rod 320, on which the microneedles 310 are disposed. The push rod 510 of the drive device 500 docks with the transmission rod 320 and can move the microneedles 310 by driving the transmission rod 320. Specifically, driven by the motor 520, the push rod 510 reciprocates along its length, and the microneedles 310 correspondingly extend and reciprocate to contact and detach from human skin, thereby penetrating the human skin to open a channel in the skin's stratum corneum.

[0154] Optionally, the drive device 500 is configured in a vertical arrangement, with the axis of the motor 520 perpendicular to the direction of movement of the push rod 510. The axis of the motor 520 is aligned with the length of the main housing 100, and the direction of movement of the push rod 510 is aligned with the width of the main housing 100. The motor 520 is positioned below the push rod 510, with the output shaft of the motor 520 arranged vertically upward and connected to the push rod 510 via a transmission wheel 530. The transmission wheel 530 may be a cam that rotates eccentrically under the drive of the motor 520 to drive the push rod 510 to move.

[0155] The push rod 510 and the microneedle device 300 can be matched in various ways, as follows:

[0156] In some embodiments, referring to Figures 9 to 11 and 13 to 14, the push rod 510 abuts against the microneedle device 300, and the auxiliary housing 200 is provided with an elastic member 540, which resets the microneedle device 300. Specifically, the microneedle device 300 is located in the forward movement direction of the push rod 510 and abuts against the push rod 510. In actual application, when the push rod 510 moves forward under the drive of the motor 520, it can correspondingly push the abutting microneedle device 300 to move, thereby pushing out the microneedles 310. During the process of pushing out the microneedles 310, the elastic member 540 continuously accumulates elastic potential energy. When the push rod 510 moves backward under the drive of the motor 520, the elastic member 540 releases its elastic potential energy, causing the microneedle device 300 to move back, thereby resetting the microneedles 310.

[0157] Optionally, the elastic member 540 is a spring. In combination with the aforementioned embodiment, the microneedle device 300 includes a transmission rod 320, and the microneedle 310 is disposed on the transmission rod 320. The spring can be sleeved on the transmission rod 320 and cooperate with the transmission rod 320. When the push rod 510 moves forward, the transmission rod 320 acts synchronously on the spring to cause the spring to accumulate elastic potential energy; when the push rod 510 moves backward, the spring can release the elastic potential energy to act on the transmission rod 320, driving the transmission rod 320 to move so as to reset the microneedle 310. In addition, during the process of pushing the microneedle 310 out, the elastic member 540 absorbs part of the force of pushing the microneedle 310 out, making the microneedle 310 more gentle on the skin and providing a better user experience.

[0158] In some embodiments, the push rod 510 is detachably connected to the microneedle device 300. Specifically, the microneedle device 300 is located in the forward direction of the push rod 510 and is detachably connected to the push rod 510, i.e., the microneedle device 300 and the push rod 510 are arranged to move with each other. In actual use, when the push rod 510 is driven forward by the motor 520, the microneedle device 300 moves with the push rod 510, thereby pushing out the microneedles 310; when the push rod 510 is driven backward by the motor 520, the microneedle device 300 moves with the push rod 510, thereby resetting the microneedles 310. The detachable connection between the push rod 510 and the microneedle device 300 can be achieved in a variety of ways, such as a snap-fit ​​connection, a magnetic connection, and the like. In conjunction with the aforementioned embodiment, the microneedle device 300 includes a transmission rod 320, on which the microneedles 310 are disposed. The end of the transmission rod 320 facing the push rod 510 may be configured with a slot. The pushing end of the push rod 510 is inserted into the slot to form a locking engagement with the transmission rod 320, allowing the transmission rod 320 to follow the push rod 510. Of course, this is merely exemplary and not restrictive. It will be appreciated that when the microneedle device 300 follows the push rod 510, it can still be combined with the elastic member 540 of the aforementioned embodiment to reduce the force exerted by the microneedles 310 on the skin and enhance the user experience.

[0159] The two matching modes of the push rod 510 and the microneedle device 300 can be selected in actual settings, and there is no limitation on this.

[0160] In some embodiments, referring to Figures 23 and 24, the end surface of the transmission wheel 530 has an eccentrically arranged transmission portion 531, the push rod 510 is provided with a chute 510a, and the transmission portion 531 is inserted into the chute 510a. The axis direction of the motor 520 is perpendicular to the movement direction of the push rod 510. Specifically, when the motor 520 drives the transmission wheel 530 to rotate, the transmission portion 531 rotates eccentrically, thereby moving along the groove wall of the chute 510a in the chute 510a of the push rod 510, thereby squeezing the groove wall of the chute 510a to move the push rod 510. The eccentric arrangement of the transmission portion 531 can be such that the rotation axis of the transmission wheel 530 is collinear with the rotation axis of the output shaft of the motor 520, and the transmission portion 531 is eccentrically arranged on the transmission wheel 530. Alternatively, the transmission wheel 530 may be eccentrically arranged, and the rotation axis of the transmission wheel 530 is not colinear with the rotation axis of the output shaft of the motor 520 , so that the transmission wheel 530 is eccentrically arranged.

[0161] Optionally, a clearance is provided between the transmission portion 531 and the wall of the chute 510a. The size of the clearance is set according to actual conditions. By reserving the clearance, there is a margin of movement when the transmission portion 531 squeezes the wall of the chute 510a, thereby ensuring effective transmission of the push rod 510 and preventing it from getting stuck.

[0162] Optionally, the eccentricity of the transmission portion 531 is less than half the length of the chute 510a. During actual operation, the motor 520 drives the transmission wheel 530 to rotate, causing the transmission portion 531 to rotate eccentrically from its initial position. The transmission portion 531 moves along the groove wall of the chute 510a toward one end of the chute 510a, thereby pressing the groove wall of the chute 510a to cause the push rod 510 to move forward. Because the eccentricity of the transmission portion 531 is less than half the length of the chute 510a, when the transmission wheel 530 rotates 180°, the transmission portion 531 will not reach the groove end of the chute 510a. As the transmission wheel 530 continues to rotate, the transmission portion 531 moves along the groove wall of the chute 510a toward the other end of the chute 510a, thereby pressing the groove wall of the chute 510a to cause the push rod 510 to move backward. That is, the motor 520 only needs to rotate in one direction, such as forward, to make the push rod 510 reciprocate. Compared with the method of rotating the motor 520 forward and reverse to drive the push rod 510 to reciprocate, it is simple to use and easy to operate.

[0163] In some embodiments, referring to FIG. 24 , the transmission portion 531 is sleeved with a rotating member 550, and the transmission portion 531 is engaged in rolling motion with the wall of the chute 510a via the rotating member 550. Specifically, when the transmission portion 531 moves in the chute 510a, the rotating member 550 rotates relative to the transmission portion 531 and rolls along the wall of the chute 510a. Through the rotating member 550, the sliding friction between the transmission portion 531 and the wall of the chute 510a is converted into rolling friction, which can extend the service life and make the transmission smoother and more flexible, helping to reduce vibration during the movement of the push rod 510. Optionally, the rotating member 550 uses a bearing, which is easy to obtain and simple to use. In addition, the rotating member 550 can also use other materials, such as a roller.

[0164] In some embodiments, referring to FIG. 16 , the beauty instrument further includes: a limiting device 600 , which is disposed on the main housing 100 . The limiting device 600 is provided with a guide groove A. The push rod 510 is passed through the guide groove A and slidably engages with the guide groove A.

[0165] In this embodiment, the guide groove A on the limiting device 600 is adapted to the push rod 510, and the push rod 510 can slide on the limiting device 600 by slidingly cooperating with the guide groove A. The structural composition and structural form of the limiting device 600 are not limited. The limiting device can be a single structural member or a combination of multiple structural members, and the guide groove A can be a single one to guide the movement of the push rod 510, or a combination of multiple ones to guide the movement of the push rod 510, which can be set according to actual conditions. During the movement of the push rod 510, the guide groove A of the limiting device 600 guides the movement of the push rod 510 so that the push rod 510 moves stably along a straight line, which can reduce the vibration of the push rod 510 mechanism and enhance the thrust, thereby ensuring the penetration effect of the microneedle 310.

[0166] Optionally, as shown in Figures 16 to 20, the limiting device 600 includes a fixed seat 610, and the guide groove A includes a first guide groove A1. The first guide groove A1 is located on the fixed seat 610, and one end of the push rod 510 is arranged through the first guide groove A1. Specifically, the first guide groove A1 is arranged through two opposite side surfaces of the fixed seat 610 and is adapted to be adapted to one end of the push rod 510. One end of the push rod 510 is arranged through the first guide groove A1. Optionally, the end of the push rod 510 that passes through the first guide groove A1 is a pushing end for pushing the microneedle device. When the push rod 510 moves, one end of the push rod 510 moves along the first guide groove A1, and the moving direction of one end of the push rod 510 is corrected by the first guide groove A1, thereby achieving the movement guidance of the push rod 510. The shape and structure of the fixed seat 610 are not limited and can be set according to actual conditions. Optionally, the fixing seat 610 is detachably connected to the main shell 100, and the detachable connection can be in the form of screw connection, snap connection, etc., which is set according to actual conditions.

[0167] A first shock absorber 1 is provided in the first guide groove A1, and the first shock absorber 1 is arranged around the push rod 510. The first shock absorber 1 can be cylindrical, with the inner wall in contact with the push rod 510 and the outer wall in contact with the groove wall of the first guide groove A1. Optionally, the first shock absorber 1 is made of silicone material, but is not limited to this. Any material that can achieve a shock-absorbing effect can be used. When the push rod 510 moves along the first guide groove A1, the first shock absorber 1 in the first guide groove A1 can buffer and dampen the push rod 510 to reduce the vibration and noise generated by the push rod 510 during movement. As another embodiment, the first shock absorber 1 can also use components such as springs to dampen the push rod 510 through the springs.

[0168] Optionally, as shown in Figures 19 and 20, the fixing seat 610 is provided with a first accommodating chamber 610A, the first accommodating chamber 610A is communicated with the first guide groove A1, and the push rod 510 passes through the first accommodating chamber 610A to be inserted into the first guide groove A1; wherein, a second shock absorber 2 is provided in the first accommodating chamber 610A, and the second shock absorber 2 is arranged around the push rod 510 and the transmission wheel 530; or, a first shock absorber 1 is provided in the first guide groove A1, the first shock absorber 1 is arranged around the push rod 510, and a second shock absorber 2 is provided in the first accommodating chamber 610A, the second shock absorber 2 is arranged around the push rod 510 and the transmission wheel 530, and the second shock absorber 2 and the first shock absorber 1 are integrally formed or separately arranged.

[0169] Specifically, one end of the push rod 510 passes through the first accommodating chamber 610A and is correspondingly passed through the first guide groove A1. The cavity structure of the first accommodating chamber 610A is adapted to the outer contour of the second shock absorber 2 for installing the second shock absorber 2. The push rod 510 passes through the second shock absorber 2, and the second shock absorber 2 is located between the push rod 510 and the transmission wheel 530 and the cavity wall of the first accommodating chamber 610A. The inner side surface of the second shock absorber 2 can contact the push rod 510 and the transmission wheel 530, and the outer side surface of the second shock absorber 2 can contact the inner wall of the first accommodating chamber 610A. The second shock absorber 2 is roughly annular. In order to match the outer contour of the push rod 510 and the transmission wheel 530, the second shock absorber 2 can be designed into a special-shaped structure. Optionally, the second shock absorber 2 is made of silicone material, but is not limited to this. Any material that can achieve a shock-absorbing effect can be used. The second shock-absorbing member 2 is provided to provide a buffer, thereby effectively reducing the vibration and noise generated by the push rod 510 during its movement and by the transmission wheel 530 transmitting the push rod 510 .

[0170] Optionally, at the same time, a first shock absorber 1 is provided in the first guide groove A1, and the first shock absorber 1 and the second shock absorber 2 are integrally formed or separately provided. As shown in FIG21 , the second shock absorber 2 can be integrally formed with the first shock absorber 1, and the first shock absorber 1 protrudes from one end face of the second shock absorber 2. In conjunction with FIG20 , during installation, the integrally formed second shock absorber 2 and the first shock absorber 1 can be inserted from the side where the first accommodating cavity 610A of the fixing seat 610 is located. When the first shock absorber 1 is inserted into place in the first guide groove A1, the second shock absorber 2 is naturally installed in the first accommodating cavity 610A. In actual application, the second shock absorber 2 and the first shock absorber 1 are integrally formed to perform shock absorption as an integral shock absorbing structure, which helps to improve the shock absorption effect. Alternatively, the second shock absorber 2 can be separately provided with the first shock absorber 1. During installation, the first shock absorbing member 1 can be inserted from the side where the first guide groove A1 of the fixing base 610 is located, and the second shock absorbing member 2 can be inserted from the side where the first accommodating cavity 610A of the fixing base 610 is located.

[0171] Optionally, referring to Figure 20, one of the second shock absorber 2 and the cavity wall of the first accommodating cavity 610A is provided with a positioning notch 1A, and the other is provided with a positioning protrusion 1B that matches the positioning notch 1A. The positioning notch 1A and the positioning protrusion 1B can be provided in one or more groups, which are set according to actual conditions. When installing the second shock absorber 2, the second shock absorber 2 can be quickly installed in the first accommodating cavity 610A by aligning and inserting the positioning notch 1A and the positioning protrusion 1B, which helps to improve the installation efficiency. In addition, after the second shock absorber 2 is installed, the movement of the second shock absorber 2 can be limited by inserting and fitting the positioning protrusion 1B and the positioning notch 1A, thereby achieving stable installation of the second shock absorber 2 in the first accommodating cavity 610A and ensuring its shock absorbing effect.

[0172] Optionally, referring to Figures 16 and 17 , the limiting device 600 further includes a guide post 620; the guide slot A includes a second guide slot A2, which is disposed on the guide post 620, and into which the other end of the push rod 510 is inserted. Specifically, the second guide slot A2 is disposed along the length of the guide post 620, with the notch of the second guide slot A2 facing the push rod 510. The other end of the push rod 510 (i.e., the end opposite the push rod end) is inserted into the second guide slot A2 for positioning. When the push rod 510 moves, the other end of the push rod 510 moves along the second guide slot A2, and the second guide slot A2 guides the movement of the other end of the push rod 510, thereby guiding the movement of the push rod 510. It is easy to understand that the second guide slot A2 and the first guide slot A1 are located on the same straight line, guiding the two ends of the push rod 510, respectively. Through the coordinated guidance of the second guide slot A2 and the first guide slot A1, the push rod 510 can move stably along a straight line. As shown in FIG17 , the guide post 620 can be disposed on the inner wall of the main housing 100 and can be integrally formed with the main housing 100 or detachably connected to the housing 110. In addition to this embodiment, the guide post 620 can also be detachably connected to the fixing base 610, and the two can be connected to form a modular whole to guide the push rod 510 and facilitate installation.

[0173] Optionally, referring to Figures 16 and 22, the other end of the push rod 510 is sleeved with a third shock absorber 3, and contacts the groove wall of the second guide groove A2 through the third shock absorber 3. The third shock absorber 3 has an opening at one end, and is sleeved on the other end of the push rod 510 through the opening. The inner wall of the third shock absorber 3 contacts the push rod 510, and the outer wall contacts the groove wall of the second guide groove A2. Optionally, as shown in Figures 16 and 22, the outer surface of the third shock absorber 3 is integrally formed with an annular protrusion 3a arranged along its circumference. The annular protrusion 3a abuts against the groove wall of the second guide groove A2. When the third shock absorber 3 absorbs shock, it deforms by squeezing the annular protrusion 3a, which can avoid obstructing the movement of the push rod 510. Optionally, the third shock absorber 3 is made of silicone material, but is not limited to this. Any material that can achieve a shock-absorbing effect can be used. When the push rod 510 moves along the second guide groove A2, the third shock absorbing member 3 can buffer and reduce the shock of the push rod 510, so as to effectively reduce the vibration and noise generated by the push rod 510 during the movement.

[0174] Optionally, the main housing 100 is provided with a third guide groove, into which the other end of the push rod 510 is inserted. That is, when the push rod 510 moves, the other end of the push rod 510 moves accordingly along the third guide groove of the main housing 100. The third guide groove of the main housing 100 guides the movement direction of the other end of the push rod 510, thereby guiding the movement of the push rod 510. Furthermore, a fourth shock absorber can be mounted on the other end of the push rod 510, so that the fourth shock absorber contacts the wall of the third guide groove. The fourth shock absorber provides cushioning and vibration reduction for the push rod 510, reducing vibration and noise. The structural configuration of the fourth shock absorber can be referred to the configuration of the third shock absorber 3 and will not be described in detail here.

[0175] Optionally, referring to Figures 18 to 20, the fixing base 610 is provided with a second accommodating chamber 610B, which accommodates the motor 520. The shape of the second accommodating chamber 610B is set according to the external structure of the motor 520. The second accommodating chamber 610B can accommodate the entire structure of the motor 520, or it can accommodate only a portion of the structure of the motor 520, and can be set according to actual conditions. Furthermore, as shown in Figures 17 and 20, when the second accommodating chamber 610B of the fixing base 610 accommodates a portion of the structure of the motor 520, the fixing base 610 cooperates with the main housing 100 to fix the motor 520. Specifically, a plurality of first reinforcing ribs B1 may be provided in the second accommodating cavity 610B to support one side of the motor 520 through the plurality of first reinforcing ribs B1, and a plurality of second reinforcing ribs B2 may be protruding from the inner wall of the main shell 100. When the fixing seat 610 is connected to the main shell 100, the plurality of second reinforcing ribs B2 of the main shell 100 support the other side of the motor 520, thereby fixing the motor 520.

[0176] The motor 520 is accommodated in the second accommodating cavity 610B so as to be positioned together with the push rod 510 on the fixing seat 610, that is, they are arranged on the same component. The relative position of the motor 520 and the push rod 510 is more stable, which helps to improve the driving stability and reduce the vibration of the push rod 510 during movement; and the motor 520, the push rod 510, the fixing seat 610, etc. can be assembled into the main shell 100 as a module, which is convenient for disassembly and assembly, and can improve assembly efficiency.
