Description

Technical Field

[0001] The utility model relates to the technical field of beauty equipment, in particular to a micro-needle care head and a beauty instrument. Background Art

[0002] As people's quality of life improves, more and more people begin to pay attention to skin care, and there are more and more types of beauty equipment with skin care functions. Among them, the most representative water light instrument uses tiny needles (microneedles) on the chip to penetrate the stratum corneum of the human epidermis, opening a large number of channels on the epidermis without damaging the epidermis, allowing the active ingredients of the essence to effectively penetrate the skin, stimulating collagen proliferation and cell regeneration, repairing aging cells, and thus achieving beauty and skin care effects.

[0003] The working mode of existing water light instrument products is usually: when the microneedles penetrate the skin, the essence is applied to the skin surface by squeezing or naturally flowing out; or the essence is applied to the skin before the microneedles penetrate the skin; or the essence is applied to the skin after the microneedles penetrate the skin. Because the channel opened by the microneedles is very small, the skin needs to overcome the surface tension of the liquid to squeeze out or apply the essence to enter the channel, which has poor absorption effect and low absorption rate, which easily leads to a large amount of essence waste.

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.

[0055] The present invention provides a microneedle care head, which is mainly used in beauty instruments (such as water light instruments and essence instruments); of course, the microneedle care head of the present application can also be applied to other types of products with similar principles.

[0056] See also Figure 1 and Figure 2 , or see Figures 6 to 8In this embodiment, the microneedle care head includes a main body 10, a movable device 20, a microneedle device 30 and an atomizing device 40. The microneedle device 30 can be, for example, a microcrystalline needle or a component with similar functions. The atomizing device 40 is a device that can atomize liquids such as essence and nutrient solution into tiny liquid particles.

[0057] The movable device 20 is arranged on the main body 10 so as to be reciprocatingly movable, and the microneedle device 30 is arranged on the movable device 20 so as to follow the movable device 20 to reciprocate relative to the main body 10; wherein the movable device 20 and the main body 10 may be connected in a sliding connection, a rotating connection, etc. The microneedle device 30 is used to break the skin of the care area, and the care area may be the skin area corresponding to the microneedle care head (for example, the skin area directly opposite to the microneedle care head, or the skin area located on the movement track of the microneedle device 30); when the movable device 20 reciprocates relative to the main body 10, the microneedle device 30 switches cyclically between the movement of approaching the care area and moving away from the care area with the movable device 20. The atomizing device 40 is disposed on the main body 10. The atomizing device 40 may be directly connected to the main body 10 (movably connected, fixedly connected or detachably connected), or may be indirectly movably connected to the main body 10 through a movable device 20, or may be indirectly fixedly connected or detachably connected to the main body 10 through other components; the atomizing device 40 is used to deliver atomized liquid (such as atomized essence or nutrient solution, etc.) to the care area.

[0058] When the microneedle care head of this embodiment is used on a beauty instrument, the movable device 20 can be connected to the driving device of the beauty instrument. When the beauty instrument is in use, the driving device drives the movable device 20 to move back and forth relative to the main body 10, so as to control the microneedle device 30 to approach the care area or return to the care area. When the driving device drives the movable device 20 to move toward the care area relative to the main body 10, so that the microneedle device 30 on the movable device 20 contacts the skin in the care area, the microneedle device 30 penetrates the contacted skin surface to open the epidermis of the skin. At the same time, the atomizing device 40 works to transport atomized liquid to the care area, so that the atomized liquid falls on the skin of the opened epidermis in the care area. In this way, the atomized liquid can quickly penetrate into the skin through the channel opened by the microneedle device 30 on the epidermis, so that the skin can absorb the atomized liquid more quickly.

[0059] The technical solution of the microneedle care head of the present embodiment adopts a movable device 20 that can be reciprocated and arranged on the main body 10, a microneedle device 30 for breaking the skin of the care area is arranged on the movable device 20, and an atomizer 40 arranged on the main body 10 transports atomized liquid to the care area; in this way, a beauty instrument using the microneedle care head of the present embodiment can drive the movable device 20 to move toward the care area relative to the main body 10 through a driving device, so that the microneedle device 30 on the movable device 20 contacts the skin of the care area to penetrate the skin epidermis and open the epidermis, and at the same time, atomized liquid is transported to the care area through the atomizer 40, so that after the microneedle device 30 opens the epidermis, atomized essence immediately reaches the skin, and because the particle size of the atomized essence is very small, it can easily penetrate into the skin through the channel opened by the microneedle, thereby effectively improving the skin's absorption effect and absorption rate of the essence, avoiding excessive essence remaining on the skin surface, and reducing the waste of essence.

[0060] In some embodiments, the direction of the reciprocating motion of the movable device 20 relative to the main body 10 is the first direction A. The first direction A may be a straight line direction, that is, the movable device 20 reciprocates along a straight line trajectory relative to the main body 10. The first direction A may also be an arc direction, that is, the movable device 20 reciprocates along an arc trajectory relative to the main body 10. In this embodiment, the microneedle device 30 is disposed at one end of the movable device 20 along the first direction A. Thus, when the movable device 20 moves along the first direction A to approach the care area, the microneedle device 30 at the end of the movable device 20 is closest to the care area, which can ensure that the microneedle device 30 will first contact the skin of the care area, so as to complete the penetration of the epidermis of the skin faster, and also avoid excessive contact of the rest of the movable device 20 with the skin to affect the user experience.

[0061] In some embodiments, the main body 10 includes a mounting member 11 extending along a first direction A, the movable device 20 includes a transmission assembly 21 and a microneedle seat 22 disposed in the mounting member 11, the microneedle seat 22 is connected to the transmission assembly 21, the microneedle device 30 is mounted on the microneedle seat 22, and at least one of the transmission assembly 21 and the microneedle seat 22 is slidably matched with the mounting member 11 in the first direction A; that is, in this embodiment, the reciprocating movement of the movable device 20 relative to the main body 10 along the first direction A is achieved by the reciprocating sliding of the transmission assembly 21 and / or the microneedle seat 22 relative to the mounting member 11 in the first direction A. When the microneedle care head of this embodiment is applied to a beauty instrument, the driving device of the beauty instrument drives the transmission assembly 21 to make the transmission assembly 21 or the microneedle seat 22 slide back and forth relative to the mounting member 11 along the first direction A, thereby controlling the microneedle device 30 to extend toward the care area or retract away from the care area.

[0062] In some embodiments, the atomizing device 40 is mounted on the mounting member 11 or the movable device 20, such as the atomizing device 40 is fixedly mounted or detachably mounted on the mounting member 11 or the movable device 20, or the atomizing device 40 is movably connected to the mounting member 11 or the movable device 20; that is, the atomizing device 40 can be fixed or movable relative to the main body 10, and the atomizing device 40 can also move back and forth relative to the main body 10 together with the movable device 20. The end of the atomizing device 40 that discharges the atomized liquid faces the microneedle seat 22, and the microneedle seat 22 is provided with an atomized liquid channel for the atomized liquid to pass through (not shown in the figure, all holes or vacancies on the microneedle seat 22 that can be used for the atomized liquid to pass through are atomized liquid channels), to prevent the atomized liquid delivered to the care area by the atomizing device 40 from being blocked by the microneedle seat 22; when the atomizing device 40 is working, the end of the atomizing device 40 that discharges the atomized liquid delivers the atomized liquid to the microneedle seat 22, and the atomized liquid delivered to the position of the microneedle seat 22 passes through the atomized liquid channel and then reaches the skin surface of the care area.

[0063] Combined with reference Figures 1 to 3 In some embodiments, an implementation scheme in which a transmission component 21 and a mounting member 11 slide together in a first direction A is as follows: the transmission component 21 includes a first push seat 211 and a plurality of first guide members 212 arranged along the first direction A, and the mounting member 11 is provided with a plurality of sliding sleeves 111 corresponding to the first guide members 212 one by one, and each first guide member 212 is slidably arranged in the corresponding sliding sleeve 111, one end of the first guide member 212 is connected to the microneedle seat 22, and the other end of the first guide member 212 is connected to the first push seat 211. In this embodiment, by applying a driving force to the first push seat 211 (for example, connecting the first push seat 211 through a driving device to apply a push or pull force along the first direction A to the first push seat 211), the first push seat 211 transmits the force received along the first direction A to the first guide member 212, so that the first guide member 212 slides relative to the sliding sleeve 111 along the first direction A, thereby driving the microneedle seat 22 connected to the first guide member 212 to slide relative to the mounting member 11 in the first direction A, so as to achieve the reciprocating movement of the microneedle device 30 relative to the main body 10 along the first direction A; and, due to the guiding role played by the cooperation of the first guide member 212 and the sliding sleeve 111, the movement of the microneedle device 30 relative to the main body 10 in the first direction A is more stable and smooth, and the user has a better experience of using the beauty instrument using the microneedle care head. In some embodiments, each first guide member 212 can be integrally formed with the microneedle seat 22.

[0064] In some embodiments, the atomizing device 40 is fixed on the mounting member 11, and the atomizing device 40 is located between the microneedle seat 22 and the first push seat 211. The atomizing device 40 or the mounting member 11 is connected to the first push seat 211 via the first elastic component 50, and the first elastic component 50 applies an elastic force to the first push seat 211 that is back to the atomizing device 40; in the process of driving the first push seat 211 to move toward the atomizing device 40 so that the microneedle device 30 moves toward the care area to contact the skin, the elastic force of the first elastic component 50 will gradually increase, and when the microneedle device 30 contacts the skin, the elastic force of the first elastic component 50 will gradually increase. When the microneedle device 30 reaches the skin, the first elastic component 50 can play a certain elastic buffering role in the contact between the microneedle device 30 and the skin, avoiding the rigid collision between the microneedle device 30 and the skin, and reducing the collision pain caused by the microneedle device 30 to the user's skin; in addition, when the driving force on the first push seat 211 is removed or the first push seat 211 is driven to move back to the atomizing device 40, the elastic force of the first elastic component 50 on the first push seat 211 can help the first push seat 211 to reset faster, avoiding the situation that the microneedle device 30 cannot be fully retracted or cannot be automatically retracted after being extended. In this embodiment, the first elastic component 50 can be composed of one or more devices such as a telescopic spring, an elastic rubber block, an elastic airbag, and a spring sheet.

[0065] In some embodiments, the transmission assembly 21 further includes a shock-absorbing rubber pad 23, which is disposed on the side of the first push seat 211 facing away from the microneedle seat 22. The shock-absorbing rubber pad 23 can be used to connect with the driving device. Through the shock-absorbing and buffering effect of the shock-absorbing rubber pad 23, the transmission noise generated by the rigid connection between the first push seat 211 and the driving device can be avoided, and the buffering effect of the microneedle device 30 colliding with the skin can be improved. Among them, the shock-absorbing rubber pad 23 can be adhesively fixed on the first push seat 211, the shock-absorbing rubber pad 23 can also be integrally formed with the first push seat 211, or the shock-absorbing rubber pad 23 can also be fixed on the first push seat 211 by fixing parts such as screws.

[0066] See also Figure 2In some embodiments, the atomizing device 40 includes a liquid storage container 41 (e.g., a liquid storage tank, a liquid storage bottle, a liquid storage box, etc.) and an atomizing sheet 42. The atomizing sheet 42 is disposed at the outlet of the liquid storage container 41, and the outlet of the liquid storage container 41 faces the microneedle seat 22. The atomizing sheet 42 may be a microporous atomizing sheet 42. When the atomizing sheet 42 is working, the liquid at the outlet of the liquid storage container 41 is sprayed toward the microneedle seat 22 through the atomizing channel to form tiny liquid particles, and then fall to the skin surface of the care area through the atomizing channel of the microneedle seat 22. The liquid storage container 41 is fixed in the mounting member 11, and a fixing component 112 is provided in the mounting member 11. The fixing component 112 fixes the atomizing sheet 42 to the outlet of the liquid storage container 41 to prevent the atomizing sheet 42 from loosening during operation, thereby causing the atomization effect to deteriorate or fail. In this embodiment, the fixed connection method between the liquid storage container 41 and the mounting member 11 can be one-piece molding, bonding, or threaded connection.

[0067] See also Figure 2 , Figure 4 and Figure 5 In some embodiments, the fixing assembly 112 includes an annular pressing piece 1121 and an annular portion 1122 provided on the inner wall of the mounting member 11, the annular pressing piece 1121 is fixedly connected to the annular portion 1122 and presses against the periphery of the atomizing sheet 42, that is, the periphery of the atomizing sheet 42 is pressed and held by the annular pressing piece 1121, so that the atomizing sheet 42 is kept pressed against the end of the outlet of the liquid storage container 41, and the spray of the atomizing sheet 42 is not blocked; wherein, the fixed connection between the annular pressing piece 1121 and the annular portion 1122 can be a buckle connection (as shown in the figure), or can be locked by a screw connection, etc. When the liquid in the liquid storage container 41 is used up or insufficient, the annular pressing piece 1121 can be removed from the annular portion 1122 to remove the atomizing sheet 42, exposing the outlet of the liquid storage container 41, so as to add liquid to the liquid storage container 41 through the outlet, and after the liquid addition is completed, the atomizing sheet 42 and the annular pressing piece 1121 can be reinstalled. Furthermore, the annular portion 1122 is provided with a plurality of positioning protrusions 11221 distributed around the atomizing sheet 42, and the positioning protrusions 11221 abut against the outer peripheral wall of the atomizing sheet 42, that is, the positioning card of the atomizing sheet 42 is in the area surrounded by the plurality of positioning protrusions 11221, so that the atomizing sheet 42 is effectively prevented from moving in the radial direction, and the abutting effect of the annular pressing sheet 1121 is cooperated to achieve the stable and reliable fixing of the atomizing sheet 42 at the outlet of the liquid storage container 41. In addition, the position of the annular pressing sheet 1121 corresponding to the first guide member 212 is also provided with a through hole for avoiding the first guide member 212, so that the first guide member 212 is passed through the annular portion 1122 without interfering with the setting of the first guide member 212.

[0068] In some embodiments, a liquid-conducting rod 43 (such as a cotton swab or a rod made of other materials that functions similarly to a cotton swab) is provided in the liquid storage container 41, one end of the liquid-conducting rod 43 abuts against the atomizing sheet 42, and the other end of the liquid-conducting rod 43 is located at the bottom end of the liquid storage container 41. The liquid-conducting rod 43 is added to the liquid storage container 41 of this embodiment, so that when the liquid level in the liquid storage container 41 is low (i.e., the remaining amount is small), the liquid level in the liquid storage container 41 can also be transmitted to the atomizing sheet 42 through the liquid-conducting rod 43, and the end of the liquid-conducting rod 43 abuts against the atomizing sheet 42, so that regardless of the height of the liquid level in the liquid storage container 41, the atomizing sheet 42 atomizes the liquid at the end of the liquid-conducting rod 43, ensuring that the amount of atomized liquid output by the atomizing device 40 is uniform and stable, so that the atomized liquid sprayed onto the skin of each care area during the care process by the beauty instrument using the microneedle care head of this embodiment is uniform.

[0069] In some embodiments, the liquid storage container 41 and the mounting member 11 can be connected by a detachable fixed connection (such as a threaded connection). In this way, when the liquid (essence, nutrient solution, water, etc.) in the liquid storage container 41 is used up or insufficient, the liquid storage container 41 can be taken out from the mounting member 11 to replenish the liquid, and then the liquid storage container 41 can be reinstalled on the mounting member 11 after the liquid is replenished; in this way, the microneedle care head can be reused many times, so that the beauty instrument using the microneedle care head of this embodiment does not need to frequently replace the microneedle care head, which greatly reduces the use cost of the beauty instrument.

[0070] In other embodiments, the liquid storage container 41 may not need to be designed to be reusable. For example, the liquid storage container 41 and the mounting part 11 may be connected in a non-detachable fixed manner (such as bonding, welding, one-piece molding, etc.); when the microneedle care head is used on a beauty instrument, after the user uses up the liquid in the liquid storage container 41 of the microneedle care head, the liquid storage container 41 is discarded together with the microneedle care head, and the beauty instrument can be replaced with a new microneedle care head for continued use.

[0071] In some embodiments, a liquid adding hole connected to the interior of the liquid storage container 41 can be provided on the mounting member 11, and the liquid adding hole can be closed by a sealing plug or a sealing cover. In this way, when the liquid in the liquid storage container 41 is used up or insufficient, the liquid adding hole can be opened to replenish the liquid into the liquid storage container 41 through the liquid adding hole, and the liquid adding hole can be closed by a sealing plug or a sealing cover after the liquid is added. In this way, the microneedle care head can also be used repeatedly, which greatly reduces the use cost of the beauty instrument using the microneedle care head of this embodiment, and there is no need to disassemble the liquid storage container 41 when adding liquid, and the liquid adding operation is more convenient.

[0072] See also Figure 3In some embodiments, each sleeve 111 is distributed between the outer peripheral wall of the liquid storage container 41 and the inner wall of the mounting member 11, that is, the liquid storage container 41 is arranged close to the central area of ​​the mounting member 11. In this way, the atomized liquid sprayed from the liquid outlet of the liquid storage container 41 through the atomizing sheet 42 is not easy to fall on the inner wall of the mounting member 11, thereby reducing the loss and waste of the atomized liquid and better ensuring the amount of atomized liquid sprayed by the microneedle care head onto the skin of the care area.

[0073] In some embodiments, the liquid storage container 41, the sliding sleeve 111 and the mounting member 11 may be integrally formed, thereby eliminating the installation process of the liquid storage container 41 and improving the production efficiency of the microneedle care head.

[0074] See also Figure 1 and Figure 2 In some embodiments, two first electrodes 60 are provided on the outer wall of the mounting member 11, and the first electrode 60 is provided with a first conductive portion 61 penetrating into the mounting member 11, and the first conductive portion 61 of one first electrode 60 is electrically connected to the positive electrode of the atomizing device 40, and the first conductive portion 61 of the other first electrode 60 is electrically connected to the negative electrode of the atomizing device 40. In this embodiment, by providing the first electrode 60 with the first conductive portion 61 on the outer wall of the mounting member 11, and connecting the positive and negative electrodes of the atomizing sheet 42 to the corresponding first conductive portions 61 respectively, the positive and negative electrodes of the atomizing sheet 42 are effectively externalized, so that when the microneedle care head is applied to the beauty instrument, the power supply of the atomizing sheet 42 is simpler, and it is only necessary to connect the two first electrodes 60 on the outer wall of the mounting member 11 to the power supply electrode of the beauty instrument. For example, when the microneedle care head is installed on the beauty instrument, the shell of the beauty instrument is provided with a power supply electrode corresponding to the position of the first electrode 60 on the outer wall of the mounting member 11. The power supply electrode is pressed by a button to make the power supply electrode contact with the first electrode 60 accordingly, thereby realizing conduction between the power supply electrode and the first electrode 60. Releasing the button disconnects the power supply electrode from the first electrode 60. Alternatively, when the microneedle care head is installed on the beauty instrument, the first electrode 60 is welded to the power supply wire on the beauty instrument, and the power supply wire is controlled to be on and off by the power switch.

[0075] In some embodiments, the first electrode 60 is located at the end of the mounting member 11 away from the microneedle seat 22. Since the microneedle device 30 needs to extend out to contact the skin of the care area, the end of the mounting member 11 close to the microneedle seat 22 is usually at one end of the beauty instrument, and the end of the mounting member 11 away from the microneedle seat 22 is close to the middle of the beauty instrument, that is, closer to the power supply part of the beauty instrument. By setting the first electrode 60 at the end of the mounting member 11 away from the microneedle seat 22, the connection design or wiring design between the first electrode 60 and the power supply part of the beauty instrument can be made more convenient.

[0076] In some embodiments, the outer wall of the mounting member 11 is provided with two annular grooves (not marked) corresponding to the two first electrodes 60, and the bottom surface of the annular groove is provided with a bayonet (not marked) penetrating into the mounting member 11. The first electrode 60 includes a conductive member surrounding the mounting member 11 and arranged in the corresponding annular groove, and at least one end of the conductive member is a first conductive portion 61, and the first conductive portion 61 is inserted into the bayonet. In this embodiment, by providing two annular grooves corresponding to the two first electrodes 60 on the outer wall of the mounting member 11, and accommodating the two first electrodes 60 in the corresponding annular grooves, the position of the first electrode 60 can be kept stable, and the first electrode 60 will not protrude from the outer wall of the mounting member 11, which has little impact on the installation of the mounting member 11, and effectively prevents the two first electrodes 60 from short-circuiting due to accidental contact. At least one end of the conductive member (i.e., the first conductive portion 61) is inserted into the bayonet, which plays a certain fixing role on the conductive member. In the figure of this embodiment, the scheme of inserting both ends of the conductive member into the bayonet is adopted, so that the conductive member is stably fixed in the annular groove. Of course, the conductive member may also be further fixed to the annular groove by bonding or screw locking.

[0077] See also Figures 6 to 8 In some embodiments, the transmission assembly 21 includes a movable member 213 sleeved on the outside of the mounting member 11, and the side wall of the mounting member 11 is provided with at least one through slot 113 arranged along the first direction A. The movable member 213 is connected to the microneedle seat 22 through a connecting member 2131 penetrating the through slot 113. When the microneedle care head of this embodiment is applied to the beauty instrument, the driving device drives the movable member 213 to move along the first direction A relative to the mounting member 11, and the connecting member 2131 moves along the through slot 113. The movable member 213 transmits a force to the microneedle seat 22 through the connecting member 2131, so as to drive the microneedle seat 22 to move synchronously along the first direction A, so as to achieve the microneedle seat 22 to approach the care area or move away from the care area along the first direction A.

[0078] In some embodiments, a second elastic component 70 is further provided between the movable part 213 and the mounting part 11, and the second elastic component 70 applies an elastic force from the microneedle seat 22 toward the atomizing device 40 to the movable part 213. In the process of driving the movable part 213 to move the microneedle device 30 toward the care area to contact the skin, the elastic force of the second elastic component 70 will gradually increase. When the microneedle device 30 contacts the skin, the second elastic component 70 can play a certain elastic buffering role in the contact between the microneedle device 30 and the skin, avoiding the rigid collision between the microneedle device 30 and the skin, and reducing the collision pain caused by the microneedle device 30 to the user's skin; in addition, when the driving force on the movable part 213 is removed or the movable part 213 is driven to move back to the atomizing device 40, the elastic force of the second elastic component 70 on the second push seat 214 can help the second push seat 214 to reset faster, avoiding the situation that the microneedle device 30 cannot be fully retracted or cannot be automatically retracted after being extended. In this embodiment, the second elastic component 70 can be composed of one or more components such as a telescopic spring, an elastic rubber block, an elastic airbag, a spring sheet, etc.

[0079] See also Figure 7 and Fig. 9 In some embodiments, the outer wall of the mounting member 11 is provided with a first deck 115, the inner wall of the movable member 213 is provided with a second deck 2132, and the second elastic component 70 includes at least one spring disposed between the first deck 115 and the second deck 2132; for example, the second elastic component 70 may include a spring sleeved on the mounting member 11, or may include multiple springs disposed around the mounting arm, and both ends of each spring abut against the first deck 115 and the second deck 2132, respectively. In the process of driving the movable member 213 to move the microneedle device 30 toward the care area to contact the skin, the second deck 2132 gradually approaches the first deck 115, the spring between the two decks is squeezed more and more, and the force generated by the spring is increasing (i.e., the elastic force exerted on the movable member 213 from the microneedle seat 22 toward the atomization device 40 is increasing).

[0080] In some embodiments, the transmission assembly 21 further includes a second push seat 214 and a plurality of second guide members 215 arranged along the first direction A, and the main body 10 further includes a fixed seat 12 fixedly connected to the mounting member 11; the fixed seat 12 is located in a space surrounded by each second guide member 215, and the second guide member 215 and the fixed seat 12 are slidably matched in the first direction A, one end of the second guide member 215 is connected to the movable member 213, and the other end of the second guide member 215 is connected to the second push seat 214; in this embodiment, by applying a driving force to the second push seat 214 (for example, connecting the second push seat 214 through a driving device to apply a pushing force or a pulling force along the first direction A to the second push seat 214), the second push seat 214 will receive the force along the first direction A The force is transmitted to the second guide member 215, so that the second guide member 215 slides along the first direction A relative to the fixed seat 12, and then the movable member 213 connected to the second guide member 215 moves in the first direction A relative to the mounting member 11, so as to drive the microneedle seat 22 to move along the first direction A, so as to realize the reciprocating movement of the microneedle device 30 relative to the main body 10 along the first direction A; and, due to the guiding role played by the cooperation between the second guide member 215 and the fixed seat 12, the driving device drives the movable member 213 through the second push seat 214 more stably and smoothly, so that the movement of the microneedle device 30 relative to the main body 10 in the first direction A is more stable and smooth, and the user has a better experience of using the beauty instrument using the microneedle care head of this embodiment. In some embodiments, each second guide member 215 can be integrally formed with the second push seat 214, and the connection between the second guide member 215 and the movable member 213 can be abutment, or can be bonding, welding, screw connection, etc.

[0081] In some embodiments, a plurality of radial protrusions 121 for connecting to the main body of the beauty instrument are arranged at intervals on the outer peripheral wall of the fixing seat 12, and each radial protrusion 121 is located between two adjacent second guide members 215. The radial protrusion 121 can limit the circumferential movement of the second guide member 215, thereby preventing the second push seat 214 from rotating along the circumferential direction following the driving device; in addition, the radial protrusion 121 can be used to cooperate with the corresponding structure on the beauty instrument housing for installation, making the installation of the microneedle care head more convenient. In the figure of this embodiment, the fixing seat 12 and the mounting member 11 are set as a split body, but in some other embodiments, the fixing seat 12 can also be integrally formed with the mounting member 11.

[0082] In some embodiments, the main body 10 further includes a connection seat 13, one end of which is plugged and fixed to one end of the mounting member 11 close to the fixing seat 12, and the other end of the connection seat 13 is buckled and fixed to the fixing seat 12, that is, in this embodiment, the fixing seat 12 and the mounting member 11 are fixedly connected through the connection seat 13. For example, one end of the connection seat 13 plugged into the mounting member 11 is buckled and fixed to the inner wall of the mounting member 11, and the other end of the connection seat 13 is pressed against the edge of the port of the mounting member 11 close to the fixing seat 12, and the fixing seat 12 is buckled to the other end of the connection seat 13.

[0083] The atomizing device 40 includes a liquid storage container 41 and an atomizing sheet 42. The atomizing sheet 42 is disposed at the outlet of the liquid storage container 41. The outlet of the liquid storage container 41 faces the microneedle seat 22. For detailed description, please refer to the aforementioned embodiment and will not be repeated here. In addition, a liquid guide rod 43 (such as a cotton swab or a rod of other materials similar to a cotton swab) may be disposed in the liquid storage container 41. One end of the liquid guide rod 43 abuts against the atomizing sheet 42, and the other end of the liquid guide rod 43 is located at the bottom of the liquid storage container 41. A liquid guiding rod 43 is added to the liquid storage container 41 of the present embodiment, so that when the liquid level in the liquid storage container 41 is low (i.e., the remaining amount is small), the liquid level in the liquid storage container 41 can be transmitted to the atomizer plate 42 through the liquid guiding rod 43, and the end of the liquid guiding rod 43 abuts the atomizer plate 42. Regardless of the liquid level in the liquid storage container 41, the atomizer plate 42 atomizes the liquid at the end of the liquid guiding rod 43, ensuring that the amount of atomized liquid output by the atomizer device 40 is uniform and stable, so that the atomized liquid sprayed onto the skin of each care area during the care process of the beauty instrument using the microneedle care head of the present embodiment is uniform.

[0084] See also Fig.10 and Fig.11 In some embodiments, the connection seat 13 has a first through hole 131 arranged along the first direction A, and the fixing seat 12 has a second through hole 121 arranged along the first direction A; the liquid storage container 41 is inserted into the first through hole 131 and the second through hole 121, and is fixed to the connection seat 13 and / or the fixing seat 12, and a positioning boss 114 is provided in the mounting member 11, and the atomizing sheet 42 abuts against the positioning boss 114 on one side facing the microneedle seat 22. That is, in this embodiment, the installation method of the liquid storage container 41 is: the outlet end of the liquid storage container 41 is inserted into the mounting member 11 through the first through hole 131 and the second through hole 121, so that the atomizing sheet 42 at the outlet of the liquid storage container 41 abuts against the positioning boss 114, and then the liquid storage container 41 is fixed to at least one of the connection seat 13 and the fixing seat 12. In this embodiment, the fixing method of the liquid storage container 41 and the fixing seat 12 and / or the connection seat 13 can be bonding, welding, threaded connection, etc.

In this embodiment, the installation method of the liquid storage container 41 is: first, the outlet end of the liquid storage container 41 is inserted into the mounting member 11 through the first through hole 131 and the second through hole 121, and then the liquid storage container 41 is screwed so that the external thread of the liquid storage container 41 is engaged with the internal thread of the hole wall of the first through hole 131 and / or the internal thread of the hole wall of the second through hole 121, until the atomization sheet 42 at the outlet of the liquid storage container 41 is pressed against the positioning boss 114, and the fixation of the liquid storage container 41 is completed. The present embodiment adopts an installation method in which the liquid storage container 41 is threadedly connected to the connecting seat 13 and / or the fixing seat 12, so that the liquid storage container 41 is easy to disassemble and install. When the liquid (essence, nutrient solution, water, etc.) in the liquid storage container 41 is used up or insufficient, the liquid storage container 41 can be removed to replenish the liquid. After the liquid is replenished, the liquid storage container 41 is reinstalled on the mounting member 11. In this way, the microneedle care head can be reused many times, so that the beauty instrument using the microneedle care head of the present embodiment does not need to frequently replace the microneedle care head, which greatly reduces the use cost of the beauty instrument.

[0086] In some embodiments, the connection method between the fixed seat 12 and the connecting seat 13 is as follows: an annular platform 132 is provided on the outer peripheral wall of the other end of the connecting seat 13 (i.e., the end of the connecting seat 13 that is not inserted into the mounting member 11), and a plurality of buckles 123 are provided on the end of the fixed seat 12 close to the connecting seat 13, the annular platform 132 is clamped between the plurality of buckles 123, and the buckles 123 buckle the side of the annular platform 132 facing the mounting member 11 (i.e., the side facing away from the fixed seat 12); that is, the fixed seat 12 clamps the annular platform 132 through the plurality of buckles 123, and cooperates with the buckles 123 to buckle the side of the annular platform 132 facing away from the fixed seat 12, thereby realizing connection and fixation with the connecting seat 13.

[0087] See also Figure 8 and Fig.11 In some embodiments, at least two second electrodes 80 are disposed on the side of the annular platform 132 facing away from the mounting member 11. The second electrode 80 has a second conductive portion that penetrates the annular platform 132. The second conductive portion of a portion of the second electrode 80 is electrically connected to the positive electrode of the atomizing sheet 42, and the second conductive portion of another portion of the second electrode 80 is electrically connected to the negative electrode of the atomizing sheet 42. Figure 7 and Fig.10, the end of the fixing seat 12 near the connecting seat 13 is provided with at least two third electrodes 90 for electrical connection with the main unit of the beauty instrument, and the third electrode 90 is in one-to-one correspondence with the second electrode 80. In the figure of this embodiment, only two second electrodes 80 and two third electrodes 90 are used as examples, that is, the second conductive part of one second electrode 80 is electrically connected to the positive electrode of the atomizing sheet 42, and the second conductive part of the other second electrode 80 is electrically connected to the negative electrode of the atomizing sheet 42; Of course, in other embodiments, the second electrode 80 and the third electrode 90 can also correspond to more (such as 3, 4, 5, etc.). In this embodiment, the second electrode 80 passes through the annular platform 132 through its second conductive part, so that the second conductive part extends to the side of the annular platform 132 close to the atomizing sheet 42, so that it is more convenient to complete the electrical connection between the atomizing sheet 42 and the second conductive part.
