[0002] In the new era, the beauty instrument industry has ushered in unprecedented development opportunities, and beauty instrument products have gradually entered people's daily lives. As one of the many types of beauty instruments, the water light instrument uses micro-needles to act on the skin at high speed to open the skin's channels, allowing the active ingredients of the essence to penetrate effectively, stimulating collagen proliferation and cell regeneration, repairing aging cells, and thus achieving beauty effects.

[0003] Currently, when the hyaluronic acid injection acts on the skin through its 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 are difficult to pass through the skin channels, resulting in a large amount of essence remaining on the skin surface and poor absorption effect.

[0077] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0078] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0079] 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 at the same time. 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 at the same time.

[0080] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0081] Based on the technical problem that the water light instrument in the prior art uses extrusion or natural outflow to apply the essence to the skin surface, resulting in poor absorption of the essence, the utility model proposes a beauty instrument to improve the absorption of the essence during skin care. Optionally, the beauty instrument in this embodiment can be a water light instrument.

[0082] Reference Figure 1 and Figure 2 The beauty instrument of this embodiment includes: a main shell 100; a sub-shell 200, which is detachably arranged on the main shell 100; a microneedle device 300, which is arranged on the sub-shell 200, and the microneedle device 300 includes a microneedle 310 for acting on the skin; an atomizer 400, which is at least partially arranged on the sub-shell 200 and located on one side of the microneedle device 300, and the atomizer 400 is used to generate a beauty spray; a driving device 500, which is arranged on the main shell 100 and acts on the microneedle device 300 to drive the microneedle 310 to move.

[0083] The main housing 100 may be in various shapes, such as a roughly square body, a cylinder, a sphere, etc., and the auxiliary housing 200 may be in a shape that matches the main housing 100, and the two are combined to form a complete housing shape. Figure 1 and Figure 2 As shown, the auxiliary housing 200 is assembled with the main housing 100 to form a complete rectangular parallelepiped.

[0084] 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 nano-wafer, 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, and when the auxiliary housing 200 is assembled to 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 reciprocates 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. In the process of its reciprocating movement, the microneedle 310 cyclically performs the extension action and the retraction action. The driving device 500 can be a one-way drive for the extension of the microneedle 310 or a one-way drive for the retraction of the microneedle 310. In this case, the output end of the driving device 500 is usually 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 for the microneedle device 300 through the elastic structure, so that the microneedle 310 can perform a retraction action or an extension action accordingly; in addition, the driving device 500 can also be a two-way drive for the extension and retraction of the microneedle 310. In this case, the output end of the driving device 500 is in a connection relationship with the microneedle device 300. Under the drive of the driving device 500, the microneedle 310 performs a retraction action or an extension action accordingly. 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 reciprocate, and also including the driving device 500 indirectly driving the microneedle device 300 to reciprocate when the driving device 500 is indirectly connected to the microneedle device 300.

[0085] In addition, the atomizing device 400 is at least partially located in the auxiliary housing 200. Optionally, the atomizing device 400 may be partially located in the auxiliary housing 200. Under this structural setting, the other part 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 parts of the atomizing device 400 may be connected for use. Alternatively, the atomizing device 400 may be entirely located on the auxiliary housing 200. The structural composition of the atomizing device 400 may be set according to actual conditions, for example, the atomizing device 400 may use an atomizing nozzle 410 or an atomizing sheet.

[0086] 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.

[0087] 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 auxiliary housing 200 and at least part of the microneedle device 300 and the atomizing device 400 are combined to form the beauty atomizing bomb. The beauty atomizing bomb is detachable from the main unit for easy daily maintenance or replacement. The beauty atomizing bomb can be a disposable beauty atomizing bomb or a reusable beauty atomizing bomb, without limitation. In the drawings shown, Figures 1 to 6 , Figures 7 to 12 , Figures 13 to 15 Three types of beauty devices with different beauty atomizer cartridges are displayed accordingly.

[0088] 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 atomizing device 400 generates a beauty spray which is sprayed onto the skin surface, enters the skin through the skin channels and is absorbed, thereby achieving a beauty effect.

[0089] When the beauty spray generated by the atomizing device 400 of the utility model is sprayed onto the skin surface, the tiny spray particles are more likely to pass through the tiny skin channels to quickly enter the skin and be absorbed, with a fast absorption speed and a good absorption effect. In addition, the spray method makes it easier to control the amount of liquid output, which can reduce the residual beauty liquid on the skin surface, thereby reducing waste.

[0090] In some embodiments, reference Figures 3 to 6 The auxiliary housing 200 has a liquid storage chamber C, and the atomizing device 400 includes:

[0091] The atomizing nozzle 410 is disposed 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.

[0092] The liquid driving mechanism 420 is used to drive the beauty liquid in the liquid storage chamber C to be delivered to the liquid passage 410a.

[0093] When the atomizing device 400 of this embodiment is working, the liquid-discharging mechanism 420 is driven to transport the beauty liquid in the liquid storage chamber C to the liquid passage 410a, and the beauty liquid flows along the liquid passage 410a to the mist outlet 410b, and forms a beauty spray at the mist outlet 410b and sprays out. Optionally, the atomizing nozzle 410 is a direct-injection atomizing nozzle 410, and the inner diameter of the liquid passage 410a is gradually set from large to small along the flow direction of the beauty liquid. After the beauty liquid is driven by the liquid-discharging mechanism 420, the inner wall of the liquid passage 410a squeezes the beauty liquid during the flow process, and after passing through the atomizing hole with a smaller aperture, it will be sprayed out at a higher speed. Under the interaction of the surface tension, viscosity and inner wall resistance of the liquid, the liquid gradually changes from a smooth flow and a wavy flow to a spray flow, and then forms a beauty spray at the mist outlet 410b to spray out, so as to achieve rapid misting.

[0094] The liquid displacing mechanism 420 may have a variety of structural arrangements. For example, the liquid displacing mechanism 420 may include a micro pump, and the liquid passage 410a is connected to the liquid storage chamber C through a liquid delivery pipeline, and the micro pump is disposed on the liquid delivery pipeline. In this way, the micro pump may be controlled to work, and under the pumping action of the micro pump, the beauty liquid in the liquid storage chamber C may be pumped 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 may also adopt other structural arrangements, which will be further described in the subsequent embodiments, and this embodiment does not limit this. In addition, the atomizing device 400 mentioned in the above 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 form a driving connection, 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. The atomizing device 400 mentioned in the above embodiment may also 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 to form a driving connection.

[0095] In some embodiments, reference Figure 3 , the liquid displacing mechanism 420 comprises:

[0096] The air pressure regulating component 421 is disposed on the main shell 100. The air pressure regulating component 421 has an air supply port 421a for connecting to the mist outlet hole 410b. The air pressure regulating component 421 is used to change the air pressure at the mist outlet hole 410b to form an air pressure difference between the air pressure at the mist outlet hole 410b and the air pressure in the liquid storage chamber C, so that the beauty liquid in the liquid storage chamber C is transported to the liquid passage 410a under the action of the air pressure difference.

[0097] The liquid-displacing mechanism 420 of this embodiment is a high-pressure liquid-displacing mechanism 420. When the auxiliary housing 200 is assembled on the main housing 100, the air supply port 421a of the air pressure regulating component 421 of the liquid-displacing mechanism 420 is connected to the mist outlet hole 410b of the atomizing nozzle 410. The air pressure at the mist outlet hole 410b can be changed by controlling the operation of the air pressure regulating component 421 to form an air pressure difference between the air pressure at the mist outlet hole 410b and the air pressure in the liquid storage chamber C. Under the action of the air pressure difference, the beauty liquid in the liquid storage chamber C obtains greater kinetic energy to flow from the liquid storage chamber C to the liquid passage 410a of the atomizing nozzle 410. Specifically, when the air pressure regulating component 421 is working, the air supply port 421a outputs a high-speed airflow and the high-speed airflow is ejected at the mist outlet hole 410b along the mist outlet direction, thereby forming a negative pressure at the mist outlet hole 410b. Since the air pressure at the mist outlet hole 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.

[0098] 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. Figure 3 As shown, after the auxiliary housing 200 and the main housing 100 are assembled, the exhaust port of the air pump is connected to the atomizing nozzle 410 through a flexible pipe; or, it can also be as follows Fig. 9 and Fig.13 As shown, 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 .

[0099] 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, an outlet flow channel is provided on the outer peripheral side of the mist outlet hole 410b of the atomizing nozzle 410, 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 arranged on the side of the atomizing nozzle 410, including but not limited to this.

[0100] In some embodiments, reference Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, the atomizing nozzle 410 includes a cover shell 411 and an inner shell 412. The inner shell 412 has two opposite sides connected to form a channel. The cover shell 411 covers the inner shell 412, and a gap is provided between at least a part of the cover shell 411 and a part of the inner shell 412.

[0101] The channel formed by the inner shell 412 is a liquid passage channel 410a, the gap between the cover shell 411 and the inner shell 412 forms an air passage channel 410c, and the end of the air passage channel 410c close to the mist outlet hole 410b forms an air outlet hole 410d; or, the gap between the cover shell 411 and the inner shell 412 forms a liquid passage channel 410a, the channel formed by the inner shell 412 is an air passage channel 410c, and the end of the air passage channel 410c close to the mist outlet hole 410b forms an air outlet hole 410d;

[0102] The air supply port 421a is communicated with the mist outlet hole 410b through the air passage 410c and the air outlet hole 410d.

[0103] In the present embodiment, the atomizer 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 atomizer 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 arranged 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.

[0104] Based on the included cover shell 411 and inner shell 412, the atomizing nozzle 410 of this embodiment may include the following two types:

[0105] The first one, such as Figure 5 and Figure 6 As shown, the channel formed by the inner shell 412 is a liquid passage channel 410a, and the gap between the cover shell 411 and the inner shell 412 forms an air passage channel 410c, and the air passage channel 410c forms an air outlet hole 410d at one end close to the mist outlet hole 410b. That is, from the front view of the atomizing nozzle 410, the liquid passage channel 410a is inside, the air passage channel 410c is outside, and the mist outlet hole 410b is located in the area of ​​the air outlet hole 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 hole 410d to form a negative pressure at the mist outlet hole 410b located in the area of ​​the air outlet hole 410d.

[0106] The second type, such as Fig.13 and Fig.14As shown, 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 an end of the air passage 410c close to the mist outlet hole 410b forms an air outlet hole 410d. 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 hole 410b is located in the area of ​​the air outlet hole 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 hole 410d to form a negative pressure at the mist outlet hole 410b located outside the area of ​​the air outlet hole 410d. Optionally, the inner shell 412 is located at the bottom wall of the liquid storage chamber C and is integrally formed with the auxiliary shell 200. The channel formed by the inner shell 412 passes through the bottom wall of the liquid storage chamber C and can be connected to the air supply port 421a. The cover shell 411 is covered with the inner shell 412, and there is a gap between the bottom of the cover shell 411 and the bottom wall of the liquid storage chamber C. Optionally, the gap is annular. The gap is formed as a channel inlet 410e of the liquid passage 410a, and the beauty liquid in the liquid storage chamber C can enter the liquid passage 410a through the gap.

[0107] In this embodiment, the atomizing nozzle 410 can be configured in any of the two aforementioned structural configurations according to actual conditions, and there is no limitation thereto.

[0108] When the atomizing nozzle 410 adopts the first atomizing nozzle 410 described above, its structure can be further configured, for example:

[0109] In some embodiments, reference Figure 5 and Figure 6 , the air passage 410c surrounds the outer peripheral side of the inner shell 412 to form a slow flow chamber H, and the shell cover is also provided with an inlet flow passage 411a, and the air supply port 421a is connected to the slow flow chamber H through the inlet flow passage 411a, and the slow flow chamber H is connected to the air outlet 410d. When the air pressure regulating component 421 is working, the high-speed airflow output by the air supply port 421a flows into the slow flow chamber H through the inlet flow passage 411a, and then flows to the air outlet 410d through the slow flow chamber H, and is ejected through the air outlet 410d. Optionally, the air intake direction of the inlet flow passage 411a is perpendicular to the air outlet direction of the air outlet 410d. Among them, the slow flow chamber H is formed by the air passage 410c surrounding the outer peripheral side of the inner shell 412, which can disperse the high-speed airflow entering from the inlet air passage 411a and guide it to the air outlet 410d for spraying, 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.

[0110] In some embodiments, reference Figure 6, one end of the inner shell 412 provided with the mist outlet hole 410b is penetrated through the air outlet hole 410d, so that the mist outlet hole 410b is located inside the air outlet hole 410d. Specifically, the air outlet hole 410d is arranged around the mist outlet hole 410b. When the air pressure regulating component 421 is working, the air outlet hole 410d circumferentially discharges air around the mist outlet hole 410b, and the air outlet is uniform, the negative pressure effect is good, and the mist outlet effect can be improved.

[0111] Alternatively, in some embodiments, one end of the inner shell 412 provided with the mist outlet hole 410b passes through the housing 411 from the air outlet hole 410d, so that the mist outlet hole 410b is protruded from the air outlet hole 410d. Specifically, when the high-speed airflow is ejected from the air outlet hole 410d, a negative pressure zone is formed at the location of the air outlet hole 410d. Due to the effect of inertia, there is a certain distance 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, which is conducive to mist discharge.

[0112] 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.

[0113] 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 amount of mist output. For example, when the required amount of 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 amount of 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 amount of mist output is large, the area ratio of the mist outlet hole 410b to the air outlet hole 410d can be set to 70%.

[0114] Optionally, the spacing between the air outlet hole 410d and the mist outlet hole 410b can be set within a range greater than 0mm and less than or equal to 0.5mm. For example, the spacing between the air outlet hole 410d and the mist outlet hole 410b can be 0.01mm, 0.25mm or 0.5mm. Optionally, the spacing 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 spacing between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.01mm; when the required mist output is medium, the spacing between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.25mm; when the required mist output is small, the spacing between the air outlet hole 410d and the mist outlet hole 410b can be set to 0.5mm.

[0115] In some embodiments, reference Figure 3 , Figure 5 , Fig. 9 and Fig.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.

[0116] In this embodiment, the liquid guide member 220 may include a liquid guide tube, and a liquid guide channel 220a is formed in the liquid guide tube. Optionally, the liquid guide tube is in an inverted L shape, the upper end of the liquid guide tube is horizontally connected to the atomizing nozzle 410, and the lower end of the liquid guide tube extends vertically toward the bottom wall of the liquid storage chamber C. When the air pressure regulating component 421 is working, an air 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 the air 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 passage 410a of the atomizing nozzle 410. Among them, the distance between the other end of the liquid guide channel 220a and the bottom wall of the liquid storage chamber C can be set to be sufficiently small, such as 0.1mm, so that the beauty liquid in the liquid storage chamber C can be fully used, which can reduce the residual amount of the beauty liquid and improve the utilization rate of the beauty liquid.

[0149] In this embodiment, the first side wall 101 and the second side wall 102 on the main housing 100 are perpendicular to each other, and the mounting position formed is L-shaped. 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 to 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 with the atomizing nozzle 410 on the auxiliary housing 200.

[0150] In combination with the above-mentioned embodiment, the first side wall 101 may be provided with a limiting groove 30, and there are two limiting grooves 30, which are arranged opposite to each other, and limiting protrusions 40 are respectively arranged on both sides of the auxiliary housing 200, and the limiting protrusions 40 are extended along the length direction of the auxiliary housing 200. During assembly, the auxiliary housing 200 can be inserted from the length direction of the main housing 100, and the limiting protrusions 40 on both sides of the auxiliary housing 200 are correspondingly inserted into the two limiting grooves 30 of the first side wall 101, so that the auxiliary housing 200 is installed at the installation position of the main housing 100.

[0151] In some embodiments, reference Figure 3 , Fig. 9 , Figures 16 to 19 The driving device 500 includes a push rod 510, a motor 520 and a transmission wheel 530. The motor 520 is located on one side of the push rod 510. The transmission wheel 530 is arranged on the output shaft of the motor 520 and is transmission-connected to the push rod 510. The push rod 510 is used to provide a force to move the microneedle 310.

[0152] When the auxiliary housing 200 is mounted on the main housing 100, the push rod 510 of the driving device 500 is docked with the microneedle device 300. When the beauty instrument is in working state, when the driving device 500 is started, the motor 520 drives the transmission wheel 530 to rotate, thereby driving the push rod 510 to move, and the push rod 510 correspondingly pushes the microneedle device 300 to move the microneedle 310. In combination with the above-mentioned embodiment, the microneedle device 300 includes a transmission rod 320, and the microneedle 310 is arranged on the transmission rod 320. The push rod 510 of the driving device 500 is correspondingly docked with the transmission rod 320, and the microneedle 310 can be moved by driving the transmission rod 320. Specifically, under the drive of the motor 520, the push rod 510 reciprocates along its length direction, and the microneedle 310 correspondingly retracts to reciprocately contact and detach from the human skin, thereby penetrating the human skin to open the stratum corneum channel of the skin.

[0153] Optionally, the structure of the driving device 500 adopts a vertical layout, and the axis direction of the motor 520 is perpendicular to the moving direction of the push rod 510. The axis direction of the motor 520 is the same as the length direction of the main housing 100, and the moving direction of the push rod 510 is the same as the width direction of the main housing 100. The motor 520 is located below the push rod 510, and the output shaft of the motor 520 is vertically arranged upward and is connected to the push rod 510 through the installed transmission wheel 530. The transmission wheel 530 can be a cam, which can be driven by the motor 520 to rotate eccentrically to drive the push rod 510 to move.

[0154] The push rod 510 and the microneedle device 300 can be matched in various ways, as follows:

[0155] In some embodiments, reference Figures 9 to 11 , Figure 13 to Figure 14 , the push rod 510 is in contact with the microneedle device 300, and the auxiliary housing 200 is provided with an elastic member 540, which provides an elastic force to reset the microneedle 310. Specifically, the microneedle device 300 is located in the forward moving direction of the push rod 510 and is in contact with 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 microneedle device 300 in contact with it to move, thereby pushing out the microneedle 310, and in the process of pushing out the microneedle 310, the elastic member 540 continuously accumulates elastic potential energy; and when the push rod 510 retreats under the drive of the motor 520, the elastic member 540 releases its elastic potential energy, so that the microneedle device 300 moves back, thereby resetting the microneedle 310.

[0156] Optionally, the elastic member 540 is a spring. In combination with the above-mentioned embodiment, the microneedle device 300 includes a transmission rod 320, and the microneedle 310 is arranged 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 on the spring synchronously so that the spring accumulates 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, and the microneedle 310 is reset by driving the transmission rod 320 to move. In addition, during the process of pushing out the microneedle 310, the elastic member 540 absorbs part of the force of pushing out the microneedle 310, so that the microneedle 310 has a softer effect on the skin and a better user experience.

[0157] 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, that is, the microneedle device 300 is arranged to follow the push rod 510. In practical applications, when the push rod 510 moves forward under the drive of the motor 520, the microneedle device 300 moves with the push rod 510, thereby pushing out the microneedle 310; and when the push rod 510 moves backward under the drive of the motor 520, the microneedle device 300 moves with the push rod 510, thereby resetting the microneedle 310. Among them, the detachable connection between the push rod 510 and the microneedle device 300 can be various, such as snap connection, magnetic connection, etc. In combination with the above-mentioned embodiment, the microneedle device 300 includes a transmission rod 320, and the microneedle 310 is arranged on the transmission rod 320. The end of the transmission rod 320 facing the push rod 510 may be configured with a slot, and the pushing end of the push rod 510 is inserted into the slot to form a clamping fit with the transmission rod 320, and the transmission rod 320 can follow the push rod 510. Of course, this is only exemplary and not restrictive. It can be understood that when the microneedle device 300 is set to follow the push rod 510, it can still be combined with the elastic member 540 of the above embodiment to reduce the effect of the microneedle 310 on the skin and improve the use experience.

[0158] The above two matching forms between the push rod 510 and the microneedle device 300 can be selected in actual settings, and there is no limitation on this.

[0159] In some embodiments, reference Fig.23 and Fig.24, the end surface of the transmission wheel 530 has an eccentrically arranged transmission part 531, the push rod 510 is provided with a slide groove 510a, the transmission part 531 is inserted in the slide groove 510a, and the axis direction of the motor 520 is perpendicular to the moving direction of the push rod 510. Specifically, when the motor 520 drives the transmission wheel 530 to rotate, the transmission part 531 rotates eccentrically, so that the transmission part 531 moves along the groove wall of the slide groove 510a in the slide groove 510a of the push rod 510, so as to move the push rod 510 by squeezing the groove wall of the slide groove 510a. Among them, the eccentric arrangement of the transmission part 531 involved can be that the rotation axis of the transmission wheel 530 is colinear with the rotation axis of the output shaft of the motor 520, and the transmission part 531 is eccentrically arranged on the transmission wheel 530. It can also be that the transmission wheel 530 is 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.

[0160] Optionally, there is a matching gap between the transmission part 531 and the groove wall of the slide groove 510a. The size of the matching gap is set according to actual conditions. By reserving the matching gap, there is a margin of movement when the transmission part 531 squeezes the groove wall of the slide groove 510a, which can ensure effective transmission of the push rod 510 to prevent jamming.

[0161] Optionally, the eccentricity of the transmission part 531 is less than half of the slot length of the chute 510a. During actual operation, the motor 520 drives the transmission wheel 530 to rotate, the transmission part 531 rotates eccentrically from the initial position, and the transmission part 531 moves along the slot wall of the chute 510a in the chute 510a to one end of the chute 510a, so as to move the push rod 510 forward by squeezing the slot wall of the chute 510a. Because the eccentricity of the transmission part 531 is less than half of the slot length of the chute 510a, when the transmission wheel 530 rotates 180°, the transmission part 531 will not reach the slot end of the chute 510a, and as the transmission wheel 530 continues to rotate, the transmission part 531 moves along the slot wall of the chute 510a in the chute 510a to the other end of the chute 510a, so as to move the push rod 510 backward by squeezing the slot wall of the chute 510a. That is, the motor 520 only needs to rotate in one direction, such as forward rotation, to make the push rod 510 reciprocate. Compared with the method in which the motor 520 rotates forward and reverse to drive the push rod 510 to reciprocate, it is simple to use and easy to operate.

[0162] In some embodiments, reference Fig.24The transmission part 531 is sleeved with a rotating member 550, and the transmission part 531 rolls with the groove wall of the chute 510a through the rotating member 550. Specifically, when the transmission part 531 moves in the chute 510a, the rotating member 550 rotates relative to the transmission part 531 and rolls along the groove wall of the chute 510a. Through the rotating member 550, the sliding friction between the transmission part 531 and the groove wall of the chute 510a is converted into rolling friction, which can extend the service life and make the transmission smoother and more flexible, which helps to reduce the vibration of the push rod 510 during movement. Optionally, the rotating member 550 adopts a bearing, which is easy to obtain and simple to use. In addition, the rotating member 550 can also adopt other materials, such as a roller.

[0163] In some embodiments, reference Fig.16 The beauty instrument further includes: a limiting device 600, which is arranged on the main housing 100, and the limiting device 600 is provided with a guide groove A, and the push rod 510 is passed through the guide groove A and slidably cooperates with the guide groove A.

[0164] In this embodiment, the guide groove A on the limit device 600 is adapted to the push rod 510, and the push rod 510 can slide on the limit device 600 by slidingly cooperating with the guide groove A. The structural composition and structural form of the limit device 600 are not limited. The limit 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 limit 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 strengthen the thrust, thereby ensuring the penetration effect of the microneedle 310.

[0165] Alternatively, if Figures 16 to 20 As shown, 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 set through the first guide groove A1. Specifically, the first guide groove A1 is set through the two opposite sides of the fixed seat 610, and is adapted to one end of the push rod 510, and one end of the push rod 510 passes through the first guide groove A1 for setting. Optionally, one end of the push rod 510 passing 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 realizing the movement guidance of the push rod 510. Among them, the shape and structure of the fixed seat 610 are not limited, and can be set according to actual conditions. Optionally, the fixed seat 610 is detachably connected to the main housing 100, and the form of the detachable connection can be screw connection, snap connection, etc., which is set according to actual conditions.

Optionally, the first shock absorbing member 1 is made of silicone material, but is not limited to this, and 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 absorbing member 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 the movement. As other implementation schemes, the first shock absorbing member 1 may also use components such as springs to dampen the push rod 510 through the springs.

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 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. As long as the material that can achieve the shock absorption effect can be used. The second shock absorbing member 2 is provided for buffering, so that the vibration and noise generated by the push rod 510 during the movement and the transmission wheel 530 driving the push rod 510 can be effectively reduced.

Fig. 20 During installation, the second shock absorber 2 and the first shock absorber 1, which are integrally formed, 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 is integrally formed with the first shock absorber 1 to perform shock absorption as an overall shock absorbing structure, which helps to improve the shock absorption effect. Alternatively, the second shock absorber 2 can be separately provided from the first shock absorber 1. During installation, the first shock absorber 1 can be inserted from the side where the first guide groove A1 of the fixing seat 610 is located, and the second shock absorber 2 can be inserted from the side where the first accommodating cavity 610A of the fixing seat 610 is located.

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 the insertion and cooperation of the positioning protrusion 1B and the positioning notch 1A, thereby achieving the stable installation of the second shock absorber 2 in the first accommodating cavity 610A and ensuring its shock absorbing effect.

Through the coordinated guidance of the second guide groove A2 and the first guide groove A1, the push rod 510 can move stably along a straight line. As shown Fig.17As shown, the guide column 620 can be disposed on the inner wall of the main housing 100 and can be integrally formed with the main housing 100 or can be detachably connected to the housing 110.
