Technical Field

[0001] This utility model relates to the technical field of water-light beauty equipment, and in particular to a beauty instrument. Background Technology

[0002] With the booming development of the beauty industry, people's demand for skin care is increasing day by day. As a result, water-light beauty devices have emerged. Traditional beauty methods, such as topical skin care products, can only keep the nutrients on the surface of the skin and cannot penetrate into the deeper layers of the skin to play a role. However, water-light beauty devices can easily introduce essence into the dermis, providing a more efficient, safe and convenient skin care experience.

[0003] Currently, there are many types of common beauty devices for skin rejuvenation. Some devices inject serum into a specific depth in the dermis, while others apply it to the skin using high-pressure jets. However, common beauty devices all have common defects, such as unstable serum output during actual use. This can affect the skincare effect or lead to serum waste. Therefore, it is necessary to improve the existing technology.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0054] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0055] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0056] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0057] The following is in conjunction with the appendix Figure 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0058] Please refer to Figure 1 and Figure 2 This utility model provides a beauty device, including a beauty device body 1, a piston 2, and a connecting rod drive assembly 3.

[0059] The beauty device body 1 has a liquid outlet channel 6 and a metering chamber 5, which is connected to the liquid outlet channel 6. A piston 2 is movably disposed in the metering chamber 5. A connecting rod drive assembly 3 cooperates with the piston 2 to control the piston 2 to squeeze the metering chamber 5, so that the essence flows from the metering chamber 5 into the liquid outlet channel 6.

[0060] Specifically, the beauty device body 1 is mainly used to provide installation positions for various components. For example, the piston 2 and the linkage drive assembly 3 can both be set on the beauty device body 1.

[0061] The metering chamber 5 contains essence, and the liquid outlet channel 6 is used to guide the essence so that it can flow from the metering chamber 5 to the outside of the beauty device body 1.

[0062] It is understood that the liquid outlet channel 6 is usually a hose structure, and the channel inside the hose forms the liquid outlet channel 6. In another embodiment, the liquid outlet channel 6 can also be a hole or groove structure. The specific arrangement of the liquid outlet channel 6 is not limited here. The liquid outlet channel 6 in this embodiment is a hose structure as an example.

[0063] The piston 2 can slide back and forth in the metering chamber 5, and the volume of the metering chamber 5 can be changed by the sliding action of the piston 2. At this time, the connecting rod drive assembly 3 cooperates with the piston 2. Specifically, the connecting rod drive assembly 3 is used to control the piston 2 to squeeze the metering chamber 5 by mechanical drive, so that the essence in the metering chamber 5 is pushed to the liquid outlet channel 6, thereby realizing the liquid outlet function.

[0064] By adopting the above-described configuration, the piston 2 can be driven by the linkage drive assembly 3 to squeeze the metering chamber 5. Since the volume of the metering chamber 5 is fixed, the piston 2 can achieve a metered liquid output effect in one squeezing process, thus solving the problem of unstable liquid output.

[0065] To ensure user convenience, the serum needs to be dispensed in measured doses repeatedly. This means that after piston 2 pushes all the serum in the dispensing chamber 5 into the dispensing channel 6, piston 2 resets, allowing new serum to re-enter the dispensing chamber 5 for the next round of dispensing. It is understandable that if the dispensing channel 6 is too long, any serum not completely delivered to the skin in time may be reabsorbed into the dispensing chamber 5 when piston 2 resets, affecting the dispensing effect. To prevent the serum pushed into the dispensing channel 6 from returning to the dispensing chamber 5, some embodiments of the beauty device also include a one-way valve 4.

[0066] Reference Figure 2 or Figure 3 In some embodiments, a one-way valve 4 is disposed in the liquid outlet channel 6 to guide the essence to flow outward through the liquid outlet channel 6.

[0067] Specifically, the one-way valve 4 has the function of controlling the one-way flow of the medium. By setting the one-way valve 4 in the liquid outlet channel 6, the essence can be guided to flow outward through the liquid outlet channel 6 to prevent the essence from flowing back from the liquid outlet channel 6 into the metering chamber 5, thus ensuring that the metered liquid dispensing is more stable and reliable.

[0068] Reference Figure 5 and Figure 6 In some embodiments, the beauty device further includes a liquid storage chamber 10, which is connected to a metering chamber 5; when the piston 2 moves to the first position, it draws the essence from the liquid storage chamber 10 into the metering chamber 5; when the piston 2 moves to the second position, it pushes the essence to the liquid outlet channel 6 and prevents the essence from flowing into the metering chamber 5.

[0069] Specifically, the volume of the reservoir 10 is larger than that of the metering chamber 5, thus allowing it to store more essence. An outlet 82 is provided through one side wall of the metering chamber 5, and the reservoir 10 is connected to the metering chamber 5 through the outlet 82. As the piston 2 moves back and forth within the metering chamber 5, it can continuously push the essence into the outlet channel 6, and at the same time, it can draw the essence from the reservoir 10 to replenish the metering chamber 5.

[0070] For ease of understanding, the inside of the metering chamber 5 is defined as the first position and the second position. The first position is located on the side of the metering chamber 5 away from the liquid outlet channel 6, while the second position is located on the side of the metering chamber 5 closer to the liquid outlet channel 6.

[0071] At this time, the motion of piston 2 includes the following states:

[0072] When piston 2 moves to the first position, piston 2 moves away from the liquid outlet channel 6 and avoids the outlet 82. A low-pressure environment is formed in the metering chamber 5, and the essence in the storage chamber 10 is drawn into the metering chamber 5 through the outlet 82 to realize the liquid replenishment function.

[0073] When piston 2 moves to the second position, piston 2 blocks the outlet 82, preventing the essence in the storage chamber 10 from flowing into the metering chamber 5, and pushes the essence in the metering chamber 5 to the outlet channel 6 to achieve the dispensing effect.

[0074] Therefore, by controlling the reciprocating motion of piston 2, the essence can be continuously and quantitatively delivered multiple times, effectively improving the skincare effect. Understandably, to ensure smooth rehydration, the reservoir 10 is equipped with a vent that connects to the atmosphere.

[0075] like Figure 5As shown, in some embodiments, the liquid storage chamber 10 is disposed on the main body 8. Specifically, the main body 8 has a partition, which surrounds the liquid storage chamber 10 within the main body 8. In this case, a pipe can be installed between the liquid storage chamber 10 and the metering chamber 5 to achieve mutual connection. In this embodiment, an independent space is separated by the partition, which can constitute the liquid storage chamber 10 for storing the essence.

[0076] In some embodiments, the main body 8 is also provided with an inlet (not shown) communicating with the liquid storage chamber 10. Through the above configuration, while ensuring the basic function of essence delivery is realized, it also supports users to inject different essences according to their needs, meeting the diverse requirements of users.

[0077] In other embodiments, combined with Figure 6 The beauty device also includes a container 11 that is detachably connected to the main body 8, and a liquid storage chamber 10 is formed in the container 11.

[0078] Specifically, the container 11 can be a vial, a soft pouch, or any other container capable of storing serum. A pin is provided on the main body 8, with an outlet 82 on the pin. The container 11 is connected to the main body 8 via the pin. This design makes serum replenishment convenient, efficient, and hygienic, and also allows for easy monitoring of the remaining serum level. In some embodiments, the pin also includes an air inlet to balance the air pressure inside and outside the container 11, ensuring smooth dispensing.

[0079] Reference Figure 2 In order to enable the essence to be quantitatively pushed into the liquid outlet channel 6, in some embodiments, the linkage drive assembly 3 includes a stepper motor 31, a first turntable 32, a first link 33, a second link 34, and a rocker arm 35.

[0080] The first turntable 32 is connected to the output shaft of the stepper motor 31. One end of the first connecting rod 33 is connected to the first turntable 32. The first turntable 32 is used to drive the first connecting rod 33 to swing eccentrically. One end of the second connecting rod 34 is connected to the piston 2. One end of the rocker arm 35 is connected to the first connecting rod 33, and the other end is connected to the second connecting rod 34. The first connecting rod 33 drives the second connecting rod 34 to swing through the rocker arm 35, so that the end of the second connecting rod 34 connected to the piston 2 reciprocates.

[0081] Specifically, the stepper motor 31 is mounted on the beauty device body 1. It is understood that the stepper motor 31 can be directly mounted on the beauty device body 1 or may be centrally mounted alongside other components; no specific mounting method is limited here. The stepper motor 31 can convert electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency, enabling precise output of the rotation angle.

[0082] The first turntable 32 is connected to the output shaft of the stepper motor 31. Normally, the first turntable 32 is fixedly connected to the output shaft of the stepper motor 31. At this time, the stepper motor 31 can drive the first turntable 32 to rotate, and one end of the first connecting rod 33 is connected to the first turntable 32 in a transmission connection. Specifically, one end of the first connecting rod 33 is rotatably connected to the edge of the first turntable 32, so that the first connecting rod 33 is eccentrically connected to the first turntable 32, and the rotation of the first turntable 32 is used to drive the first connecting rod 33 to eccentrically swing.

[0083] One end of the second connecting rod 34 is connected to the piston 2 via a transmission connection. Specifically, one end of the second connecting rod 34 and the piston 2 can be detachably connected or abut against each other. Both connection methods enable the second connecting rod 34 to push the piston 2 to move, and no limitation is made here. It is understood that one end of the second connecting rod 34 and the piston 2 can be detachably connected, specifically by means of snap-fit, screw connection, magnetic attraction, etc., to facilitate disassembly.

[0084] The rocker arm 35 is located between the first link 33 and the second link 34, and is rotatably mounted on the beauty device body 1. Specifically, the middle part of the rocker arm 35 is rotatably mounted on the beauty device body 1. At this time, both ends of the rocker arm 35 can rotate around the middle part as the axis of rotation. It can be understood that the rotatable connection referred to here can be understood as the rocker arm 35 being directly mounted on the beauty device body 1 or possibly having a centrally mounted component. The specific rotational setting of the rocker arm 35 is not limited here.

[0085] Based on this, one end of the rocker arm 35 is connected to the first connecting rod 33, and the other end is connected to the second connecting rod 34. Specifically, one end of the rocker arm 35 is rotatably connected to the end of the first connecting rod 33 away from the first turntable 32, and the other end of the rocker arm 35 is rotatably connected to the end of the second connecting rod 34 away from the piston 2. The rocker arm 35 connects the first connecting rod 33 and the second connecting rod 34 under force. The stepper motor 31 drives the first connecting rod 33 to swing. During the swinging process of the first connecting rod 33, the first connecting rod 33 can push the rocker arm 35 to rotate. At this time, the rocker arm 35 can amplify the torque, and the first connecting rod 33 drives the second connecting rod 34 to swing through the rocker arm 35, so that the second connecting rod 34 pushes the end of the piston 2 to produce reciprocating motion.

[0086] Based on the above scheme, the connecting rod drive assembly 3 forms a crank-connecting rod transmission structure. The rocker arm 35 mechanism can amplify the torque of the stepper motor 31, thereby driving the second connecting rod 34 to push the piston 2 to move, obtaining a stable thrust, and the liquid discharge action is stable and reliable.

[0087] Reference Figure 3 In other embodiments, the linkage drive assembly 3 includes a geared motor 36, a second turntable 37, a third link 38, and a push rod 39.

[0088] The second turntable 37 is connected to the output shaft of the geared motor 36. One end of the third connecting rod 38 is connected to the second turntable 37 for transmission. The second turntable 37 is used to drive the third connecting rod 38 to swing eccentrically. One end of the push rod 39 is connected to the other end of the third connecting rod 38 for transmission. The third connecting rod 38 is used to drive the push rod 39 to reciprocate. The other end of the push rod 39 is engaged with the piston 2 and is used to push the piston 2 to move.

[0089] Specifically, the geared motor 36 is mounted on the beauty device body 1. It can be understood that "mounted" here means that the geared motor 36 can be directly mounted on the beauty device body 1 or may be a centrally mounted component; the specific mounting method of the geared motor 36 is not limited here. Furthermore, the geared motor 36 is a type of motor component with a reduction module, capable of outputting greater torque; the specific structure of the geared motor 36 is not limited here.

[0090] Based on this, the second turntable 37 is connected to the output shaft of the geared motor 36. Typically, the second turntable 37 is fixedly mounted on the output shaft of the geared motor 36, which drives the second turntable 37 to rotate. One end of the third connecting rod 38 is connected to the second turntable 37. Typically, one end of the first connecting rod 33 is rotatably mounted on the edge of the second turntable 37, which drives the third connecting rod 38 to eccentrically swing. Additionally, one end of the push rod 39 is connected to the other end of the third connecting rod 38. Specifically, one end of the push rod 39 is rotatably connected to the other end of the third connecting rod 38, and the push rod 39 is slidably mounted on the beauty device body 1. It is understood that the sliding installation method of the push rod 39 referred to here could be that the push rod 39 is directly slidably mounted on the beauty device body 1, or it may also have a centrally positioned component. No specific limitation is made on the specific arrangement of the push rod 39.

[0091] The slidingly mounted push rod 39 can move linearly, allowing the third connecting rod 38 to drive the push rod 39 to reciprocate. At this time, the end of the push rod 39 away from the third connecting rod 38 engages with the piston 2; specifically, the two abut against each other, and the push rod 39 pushes the piston 2 to move. Based on the above scheme, a crank-connecting rod structure is formed, which can also achieve the liquid discharge function. Compared to the previous embodiment, where the geared motor 36 itself has a reduction gear, which amplifies torque during transmission, this scheme eliminates the need for the rocker arm 35 by using the geared motor 36, making the transmission more efficient and faster, and simplifying the structure.

[0092] Reference Figure 2 or Figure 3 After piston 2 pushes the essence into the outlet channel 6, piston 2 resets so that new essence can re-enter the metering chamber 5, thus enabling the next round of metered dispensing.

[0093] In order to enable the piston 2 to reset stably, in some embodiments, the connecting rod drive assembly 3 also includes a return spring 14.

[0094] Specifically, the return spring 14 is located inside the metering chamber 5, and its two ends are connected to the piston 2 and the inner wall of the metering chamber 5, respectively. The return spring 14 is used to drive the piston 2 to return to its original position. It can be understood that when the piston 2 is driven by the connecting rod drive assembly 3 to press against the metering chamber 5, the return spring 14 is compressed and stores force; when the driving force of the connecting rod drive assembly 3 on the piston 2 is removed or the piston 2 is driven to move in the opposite direction, the return spring 14 is released and applies a return force to the piston 2 to drive it to return to its original position, thereby allowing new essence to re-enter the metering chamber 5.

[0095] In some embodiments, when the connecting rod drive assembly 3 is a crank-connecting rod structure, in order to avoid the structure from generating dead points, a micro switch 12 is also included. The first turntable 32 or the second turntable 37 is provided with a protrusion 13 that abuts and cooperates with the micro switch 12. When the piston 2 is displaced to the maximum stroke, the protrusion 13 abuts against the micro switch 12 so that the micro switch 12 controls the connecting rod drive assembly 3 to stop discharging liquid.

[0096] Reference Figure 3 and Figure 4 The micro switch 12 is a switching element that is triggered by a tilted contact. It has two types: press-triggered and release-triggered. The following embodiment uses the press-triggered micro switch 12 as an example. It generates a trigger signal by pressing the spring. On this basis, the protrusion 13 is integrally connected to the periphery of the first turntable 32 or the periphery of the second turntable 37, and the protrusion 13 abuts and cooperates with the spring of the micro switch 12.

[0097] The micro switch 12 and the protrusion 13 have the following states:

[0098] When the essence is fully loaded in the metering chamber 5, the linkage drive assembly 3 retracts inward. At this time, the protrusion 13 releases the spring of the micro switch 12, and the micro switch 12 is in an untriggered state.

[0099] When piston 2 moves to its maximum stroke, all the essence in metering chamber 5 is pushed by piston 2 to liquid outlet channel 6. At this time, linkage drive assembly 3 extends, and protrusion 13 moves closer to spring plate as the first turntable 32 or the second turntable 37 rotates, causing protrusion 13 to press micro switch 12. At this time, micro switch 12 is turned on and generates a trigger signal. Based on the trigger signal, micro switch 12 controls linkage drive assembly 3 to stop driving to pause liquid outlet.

[0100] Understandably, to achieve the control effect, the beauty device body 1 is equipped with a circuit board, on which a main control chip is installed. The output terminal of the micro switch 12 is electrically connected to the receiving terminal of the main control chip. Therefore, a trigger signal can be input to the main control chip, which generates a control signal based on the trigger signal. The output terminal of the main control chip is electrically connected to the stepper motor 31 or the geared motor 36. By sending the control signal to the stepper motor 31 or the geared motor 36, the stepper motor 31 or the geared motor 36 is stopped or reset. At this time, the essence in the metering chamber 5 has been completely pushed into the liquid outlet channel 6, achieving a metered liquid outlet effect. It also prevents the first turntable 32 or the second turntable 37 from continuing to rotate to the dead point, preventing structural jamming and making the structural operation more reliable and stable.

[0101] Continue to refer to Figure 3 and Figure 4In order to ensure that the essence can be accurately applied to the user's skin, the beauty device provided in this application also includes a beauty head 7.

[0102] In some embodiments, the beauty head 7 has a liquid outlet 71 that communicates with the liquid outlet channel 6. Based on the above configuration, the beauty head 7 can be directly disposed at one end of the beauty device body 1 (not shown in the figure), and the essence can flow to the beauty head 7 through the liquid outlet 71. In actual use, the beauty head 7 can be attached to the skin care area, and the location of the beauty head 7 is the skin care position of the beauty device, achieving a precise liquid application effect.

[0103] In other embodiments, the beauty head 7 has a liquid outlet hole 71 that communicates with the liquid outlet channel 6, and the beauty head 7 is also provided with microneedles and / or electrodes, the microneedles and / or electrodes and the liquid outlet hole 71 being located on the same surface of the beauty head 7.

[0104] It should be explained that when the beauty head 7 is equipped with electrodes, the electrodes can be electrically connected to the circuit board on the beauty device body 1. The circuit board is equipped with a power module, which distributes electrical energy to the electrodes to achieve the electrotherapy skincare effect. Specifically, when the beauty head 7 is equipped with electrodes, the electrodes can release microcurrents, which can broaden the absorption channels on the user's skin, thereby promoting absorption and optimizing the skincare effect.

[0105] When the beauty head 7 is equipped with microneedles, the microneedles can be used to widen and form channels on the user's skin, allowing the essence to penetrate deeper into the skin more easily, promoting absorption and optimizing skincare effects.

[0106] When the beauty head 7 is equipped with both microneedles and electrodes, multiple combined penetration-enhancing effects can be achieved, further optimizing and improving the skincare results.

[0107] Please refer to Figure 2 , Figure 4 In some embodiments, the beauty device further includes a main body 8. A metering chamber 5 and a liquid outlet channel 6 are disposed on the main body 8, and the main body 8 is provided with a first clearance hole 81 for the linkage drive assembly 3 to cooperate with the piston 2.

[0108] Specifically, the main body 8 has a shell structure with a hollow interior. The metering chamber 5 and the liquid outlet channel 6 are located inside the main body 8. The main body 8 serves to integrate the liquid outlet channel 6 and the metering chamber 5. In some embodiments, the main body 8 is provided with a pipe structure, the metering chamber 5 is formed inside the pipe, and one end is connected to the liquid outlet channel 6.

[0109] Based on the above configuration, on the one hand, the overall compactness of the structure can be improved and the layout of the beauty device can be simplified; on the other hand, since the main body 8 integrates the metering chamber 5 and the liquid outlet channel 6 together, it is only necessary to install the main body 8 on the beauty device body 1 to simultaneously set the metering chamber 5 and the liquid outlet channel 6 on the beauty device body 1, which facilitates the manufacturing and installation of components such as the metering chamber 5 and the liquid outlet channel 6.

[0110] In addition, the main body 8 is also provided with a first clearance hole 81, which is connected to the metering chamber 5. The connecting rod of the linkage drive assembly 3 can extend into the metering chamber 5 from the outside through the first clearance hole 81. The first clearance hole 81 plays a clearance role and can meet the liquid pushing action requirements of the linkage drive assembly.

[0111] Understandably, there are multiple ways to set up the beauty head 7. As mentioned earlier, the beauty head 7 can be directly set on the beauty device body 1. In this case, the beauty head 7 is directly and fixedly installed on the beauty device body 1, and the beauty device body 1 provides support for the beauty head 7.

[0112] In another configuration of the beauty head 7, the beauty head 7 is connected to the main body 8. In this case, by placing the main body 8 on the beauty device body 1, the beauty head 7 is indirectly placed on the beauty device body 1 through the main body 8. The difference between this configuration and directly placing the beauty head 7 on the beauty device body 1 is that by connecting the main body 8 and the beauty head 7, the main body 8 and the beauty head 7 form a beauty component that can be integrated for production, facilitating manufacturing. This embodiment uses a configuration where the beauty head 7 and the main body 8 are mutually fixed as an example.

[0113] It is understood that no restrictions are placed on the specific combination of the beauty head 7 and the main body 8. Regardless of the setting method of the beauty head 7, as long as any of the above methods are used, they should be included in the scope of alternative means of this solution.

[0114] Alternatively, the main body 8 can also be configured in several ways compared to the beauty device body 1.

[0115] In some embodiments, the main body 8 is fixedly disposed inside the beauty device body 1, which ensures that the main body 8 and the beauty head 7 can work stably and are not easily detached.

[0116] In some embodiments, a fastening mechanism is provided between the beauty device body 1 and the main component 8. This allows the main component 8 to be detachably mounted on the beauty device body 1 via the relevant fastening mechanism. In this case, the main component 8 can not only be stably mounted, but the entire beauty component can also be disassembled relative to the beauty device body 1. This facilitates the periodic replacement of the beauty component to maintain a clean and hygienic operating condition for the beauty device. In addition, the main component 8 can also be indirectly mounted on the beauty device body 1 through other components. The specific installation method of the main component 8 is not limited here.

[0117] Reference Figure 3 and Figure 4 In the embodiments of this application, a vibration mechanism 9 is also included. The vibration mechanism 9 is connected to the main body 8, and the linkage drive assembly 3 is disposed on the vibration mechanism 9. The vibration mechanism 9 is used to drive the main body 8 and the linkage drive assembly 3 to reciprocate simultaneously, thereby driving the beauty head 7 to reciprocate.

[0118] Based on the above configuration, the vibration mechanism 9 is located on the beauty device body 1 and connected to the beauty head 7. It can drive the beauty head 7 to pat the skin. On the one hand, it can have a massage effect and further open the absorption channels. On the other hand, with the beauty head 7 equipped with microneedles, it can also achieve an automatic puncture effect, and the absorption efficiency of the essence is significantly improved.

[0119] It should be noted that the connection between the main body 8 and the vibration mechanism 9 is equivalent to indirectly mounting the main body 8 onto the beauty device body 1 via the vibration mechanism 9. Based on this, the main body 8 can be fixedly connected to the vibration mechanism 9, or it can be detachably connected to the vibration mechanism 9; therefore, regardless of whether the main body 8 is directly mounted on or indirectly mounted on the beauty device body 1, or whether it is fixedly mounted or detachably mounted, any of the above-mentioned mounting methods should be included within the scope of this application. In the following embodiments, the main body 8 is detachably mounted on the vibration mechanism 9 as an example.

[0120] Continue to refer to Figure 3 and Figure 4 In some embodiments, the vibration mechanism 9 includes a vibration motor 91 and a vibration connector 92. The vibration motor 91 is disposed on the beauty instrument body 1, the vibration connector 92 is connected to the output shaft of the vibration motor 91, and the main body 8 and the connecting rod drive assembly 3 are disposed on the vibration connector 92. The vibration connector 92 has a second clearance hole 921, and the connecting rod drive assembly 3 cooperates with the piston 2 through the first clearance hole 81 and the second clearance hole 921.

[0121] Based on the above technical solution, the vibration motor 91 is fixedly installed inside the beauty device body 1. The vibration motor 91 can output stable vibration and transmit the vibration force to the main body 8 through the vibration connector 92, thus realizing the vibration care function of the beauty head 7.

[0122] In some embodiments, the vibration connector 92 includes a mounting sleeve 922 for inserting and removing the main body 8, and a second clearance hole 921 is provided on the mounting sleeve 922.

[0123] In some embodiments, the mounting sleeve 922 has an elongated sleeve-like structure, is hollow inside, and is open at one end. The main body 8 is plugged into and detached from the mounting sleeve 922 through the open end of the mounting sleeve 922. It is understood that when the main body 8 is inserted into the mounting sleeve 922, the beauty head 7 is exposed at the open end of the mounting sleeve 922. A second clearance hole 921 is provided at the other end of the mounting sleeve 922 to facilitate the linkage drive assembly 3 acting on the piston 2 to achieve liquid dispensing.

[0124] In order to enable the main body 8 to be detachably mounted on the vibration mechanism 9, in some embodiments, a first fastening position is provided on the mounting sleeve 922, and a second fastening position is provided on the main body 8 to be movably fastened to the first fastening position.

[0125] Specifically, the first fastener is located on the inner wall or open end of the mounting sleeve 922, and the second fastener is located on the outer peripheral wall of the main body 8. The movable engagement of the first and second fasteners allows the main body 8 to be disassembled and reassembled relative to the vibration mechanism 9, thus enabling regular replacement of the beauty components and maintaining a hygienic skincare environment.

[0126] In other embodiments, the mounting sleeve 922 may be a claw-shaped structure. In this case, the mounting sleeve 922 may include multiple claw fingers, the main body 8 may be fixed by the multiple claw fingers, and the second clearance hole 921 may be the gap between the claw fingers.

[0127] Furthermore, the claw fingers of the mounting sleeve 922 are provided with a first fastening position, and the main body 8 is provided with a second fastening position that is movably engaged with the first fastening position.

[0128] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
