[0044] 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.

[0045] 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.

[0046] 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.

[0047] The following is in conjunction with the appendix Figure 1-5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0048] Please refer to Figure 1 and Figure 2 This utility model provides a quantitative beauty instrument, including a beauty instrument body 1, a piston 2, a driving component 3, an opening and closing valve 4, and a control component 5.

[0049] The beauty device body 1 has a liquid storage chamber 6 and a liquid outlet channel 7 connected to the liquid storage chamber 6. The liquid storage chamber 6 is used to contain essence. The piston 2 is movably disposed in the liquid storage chamber 6. The driving component 3 is used to drive the piston 2 to move so as to squeeze the essence into the liquid outlet channel 7. The opening and closing valve 4 is disposed in the liquid outlet channel 7. The control component 5 is connected to the opening and closing valve 4. The control component 5 is used to control the opening and closing valve 4 to open or close the liquid outlet channel 7.

[0050] Specifically, the beauty device body 1 provides installation positions for various components. For example, the piston 2, drive component 3, and control component 5 can be set on the beauty device body 1. The liquid outlet channel 7 is used to guide the essence, so that the essence can flow from the liquid storage chamber 6 to the outside of the beauty device body 1.

[0051] Typically, in some embodiments, the liquid outlet channel 7 can be a flexible tube structure, with the channel inside the flexible tube forming the liquid outlet channel 7. In other embodiments, the liquid outlet channel 7 can also be obtained by setting holes or grooves on the beauty device body 1. The liquid outlet channel 7 provided in this embodiment is a flexible tube structure as an example. Here, the specific setting method of the liquid outlet channel 7 is not limited.

[0052] Based on this, the piston 2 can slide back and forth in the liquid storage chamber 6, and the volume of the liquid storage chamber 6 can be changed by the displacement of the piston 2. At this time, the driving component 3 cooperates with the piston 2. The driving component 3 is used to drive the piston 2 to move, so as to squeeze the essence into the liquid outlet channel 7. The piston 2 obtains a power source under the action of the driving component 3.

[0053] Furthermore, the opening and closing valve 4 is movably disposed within the liquid outlet channel 7, and under the action of the control component 5, the opening and closing valve 4 has the function of movably opening and closing the liquid outlet channel 7.

[0054] Based on the above configuration, under the drive of the drive component 3, the piston 2 can squeeze the liquid storage chamber 6, thereby forcing the essence to flow from the liquid storage chamber 6 to the liquid outlet channel 7. Under the guidance of the liquid outlet channel 7, the essence flows out to the outside of the beauty device body 1, achieving the liquid outlet effect. During this process, the control component 5 can control the opening and closing of the valve 4, thereby controlling whether the essence can pass through the liquid outlet channel 7. By controlling the outflow time of the essence, the overall liquid output can be precisely controlled.

[0055] Reference Figure 2 In some embodiments, the driving component 3 includes a first air source 31, which is connected to the liquid storage chamber 6 and is used to introduce gas into the liquid storage chamber 6 to push the piston 2 to move.

[0056] Specifically, the first air source 31 is usually an air pump element. The first air source 31 has an air outlet end, which is connected to the liquid storage chamber 6 through a pipe. Here it is defined as the first pipe 32. The first air source 31 can continuously supply pressurized gas into the liquid storage chamber 6 through the first pipe 32, thereby driving the piston 2 to squeeze the essence in the liquid storage chamber 6 to achieve the liquid discharge effect. During this process, the piston 2 can obtain stable pressure, and the piston 2 moves smoothly and stably.

[0057] In other embodiments, the driving component 3 can also be mechanically driven to displace the piston 2. For example, the driving component 3 can be a stepper motor, a lead screw, and a push rod. The lead screw is connected to the output shaft of the stepper motor, which drives the lead screw to rotate. The lead screw is also connected to the push rod, which drives the push rod to reciprocate. The push rod abuts against the piston 2, and the push rod can push the piston 2 to displace, thereby achieving the liquid discharge effect.

[0058] Alternatively, in other embodiments, the driving component 3 for displacing the piston 2 can be a stepper motor, a gear, and a rack. The gear is connected to the output shaft of the stepper motor and meshes with the rack. In this case, the stepper motor can drive the gear to rotate, thereby pushing the rack to move back and forth. The rack abuts against the piston 2, and the rack can push the piston 2 to squeeze the liquid storage chamber 6 to achieve the liquid discharge effect.

[0059] It is understandable that regardless of whether the driving component 3 is gas-driven or mechanically driven, as long as it can drive the piston 2 to squeeze the liquid storage chamber 6, it should be included in the scope of the interpretation of the driving component 3. The specific structure of the driving component 3 is not limited here.

[0060] Reference Figure 2 In some embodiments, in order to drive the opening and closing valve 4 to open or close, the control component 5 includes a two-way air valve 51, one end of which is connected to the first air source 31, and the other end of which is connected to the opening and closing valve 4.

[0061] Specifically, the two-way valve 51 has an inlet end and an outlet end. The outlet end of the two-way valve 51 is connected to the outlet end of the first gas source 31. Typically, the two-way valve 51 and the first gas source 31 are connected to each other through a pipe, which is defined here as the second pipe 52. At this time, one end of the two-way valve 51 is connected to the first gas source 31, and the gas generated by the first gas source 31 can flow to the two-way valve 51 through the second pipe 52.

[0062] At the same time, a pipe is also provided between the outlet end of the two-way vent valve 51 and the on / off valve 4, which is defined here as the third pipe 53. At this time, by controlling the two-way vent valve 51, the gas can flow through the third pipe 53 into the on / off valve 4, thereby realizing the opening and closing control of the on / off valve 4.

[0063] By adopting the above scheme, the two-way vent valve 51 controls the gas flow to the on / off valve 4, thereby sensitively controlling the opening or closing of the on / off valve 4, resulting in efficient operation. Simultaneously, the gas generated by the first gas source 31 can also be used to control the opening or closing of the on / off valve 4, resulting in a compact structure and highly efficient operation.

[0064] Reference Figure 3 In some other embodiments, the control component 5 includes a second air source 54 connected to the on / off valve 4, and the second air source 54 is used to supply pressure to open or close the on / off valve 4.

[0065] Specifically, the second air source 54 is also an air pump element. The air outlet of the second air source 54 is connected to the on-off valve 4 through a pipe to control the on-off valve 4. Correspondingly, this pipe is also defined as the third pipe 53.

[0066] In the above scheme, a dual-gas-source control method is adopted. Compared with the single-gas-source control method used above, the dual-gas-source control method can also control the opening and closing valve 4. In addition, the dual-gas-source has a higher gas output pressure, more stable liquid output, and can optimize and improve the liquid output effect.

[0067] Looking back Figure 2 In the embodiments of this application, the on / off valve 4 includes a valve core 41 and a return spring 42. The valve core 41 is movably disposed in the liquid outlet channel 7, and the return spring 42 is connected to the valve core 41.

[0068] When the opening and closing valve 4 opens the liquid outlet passage 7, the control component 5 starts and applies pressure to the valve core 41, and compresses the return spring 42.

[0069] When the on / off valve 4 closes the liquid outlet channel 7, the control component 5 closes and the return spring 42 extends.

[0070] Specifically, the valve core 41 includes a housing 411 and a core 412. The housing 411 is fixedly disposed in the liquid outlet channel 7, and the housing 411 is hollow inside and communicates with the liquid outlet channel 7. In addition, the housing 411 has a groove inside that allows the valve core 41 to slide back and forth. The core 412 is a silicone valve core 41, which is movably disposed in the groove. One end of the return spring 42 is connected to the valve core 41 and is used to drive the valve core 41 to return to its original position.

[0071] Specifically, one end of the return spring 42 abuts against the core 412, and the other end abuts against the inner wall of the outer shell 411. At this time, the control component 5 is used to introduce pressure into the outer shell 411 and push the core 412 to compress the return spring 42. When the pressure is removed, the return spring 42 can drive the core 412 to reset.

[0072] Meanwhile, the valve core 41 has a through hole in the middle. During the sliding process of the valve core 41, the through hole can communicate with the liquid outlet channel 7. At this time, the valve core 41 opens the liquid outlet channel, and the essence can be output to the skin through the liquid outlet channel 7 and the through hole. Alternatively, during the sliding process of the valve core 41, the through hole and the liquid outlet channel 7 are misaligned, which can prevent the core body 412 from flowing through the liquid outlet channel 7, thereby closing the liquid outlet channel 7.

[0073] Based on the above settings, the on / off valve 4 has the following states:

[0074] When the opening and closing valve 4 opens the liquid outlet channel 7, the control component 5 starts and applies pressure to the valve core 41, and compresses the return spring 42. At this time, the through hole on the core 412 is connected to the liquid outlet channel 7, and the essence can be output to the skin through the liquid outlet channel 7 and the through hole on the core 412.

[0075] When the opening and closing valve 4 closes the liquid outlet channel 7, the control component 5 is closed, that is, the airflow into the opening and closing valve 4 is cut off. At this time, the return spring 42 extends and the core 412 returns to its original position. The through hole and the liquid outlet channel 7 are offset from each other, so that the core 412 blocks the liquid outlet channel 7, thereby making the through hole on the core 412 and the liquid outlet channel 7 not connected to each other.

[0076] By adopting the above scheme, the liquid discharge action can be sensitively controlled to meet the actual needs of the liquid discharge function. In addition, in other embodiments, the control component 5 can also be a mechanical mechanism. For example, the core 412 can be pressed down by mechanical drive, or the core 412 can be displaced by electromagnetic force. Alternatively, the opening and closing valve 4 can be set as a valve body structure that can be rotated to open. The control component 5 drives the valve body to rotate to realize the opening and closing of the opening and closing valve 4. The above methods can also play the role of controlling the liquid flow. The specific structure of the control component 5 is not limited here. As long as it can control the opening and closing of the opening and closing valve 4, it should be included in the scope of interpretation of this scheme.

[0077] Continue to refer to Figure 3 In 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 8.

[0078] In some embodiments, the beauty head 8 has a liquid outlet hole 81 that communicates with the liquid outlet channel 7. Based on the above configuration, the beauty head 8 can be directly set at one end of the beauty device body 1, and the essence can flow to the beauty head 8 through the liquid outlet hole 81. In actual use, the beauty head 8 can be attached to the skin care area, and the location of the beauty head 8 is the care position of the beauty device, so as to achieve a precise liquid application effect.

[0079] In other embodiments, the beauty head 8 has a liquid outlet hole 81 that communicates with the liquid outlet channel 7, and the beauty head 8 is also provided with microneedles and / or electrodes, the microneedles and / or electrodes and the liquid outlet hole 81 being located on the same surface of the beauty head 8.

[0080] It should be explained that when the beauty head 8 is equipped with electrodes, these 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, thereby achieving an electrotherapy skincare effect. Specifically, when the beauty head 8 has electrodes, they can release microcurrents, which can widen the absorption channels on the user's skin, promoting absorption and optimizing skincare results. Based on the above setup, when the beauty head 8 is equipped with microneedles, these microneedles can create absorption channels on the user's skin, allowing the serum to penetrate deeper into the skin more easily, promoting absorption and optimizing skincare effects.

[0081] When the beauty head 8 is equipped with both microneedles and electrodes, multiple combined penetration-enhancing effects can be achieved, further optimizing and improving the skincare results.

[0082] Continue to refer to Figure 3 In some possible embodiments of this application, the main body 9, the on / off valve 4, the liquid storage chamber 6 and the liquid outlet channel 7 are disposed on the main body 9. The main body 9 is connected to the beauty head 8. The main body 9 is provided with a first clearance hole 91, which is used for the drive component 3 to cooperate with the piston 2 located in the liquid storage chamber 6. The main body 9 is also provided with a second clearance hole 92, which is used for the control component 5 to cooperate with the on / off valve 4.

[0083] Specifically, the main body 9 has a shell structure with a hollow interior. The on / off valve 4, the liquid storage chamber 6, and the liquid outlet channel 7 are located inside the main body 9. The main body 9 integrates the liquid outlet channel 7 and the liquid storage chamber 6. In this embodiment, a partition structure is provided inside the main body 9. The partition encloses a portion of the main body 9 to form the liquid storage chamber 6, and one end of the partition is connected to the liquid outlet channel 7.

[0084] Based on the above configuration, on the one hand, since the main body 9 integrates the liquid storage chamber 6 and the liquid outlet channel 7 together, it can improve the overall compactness of the structure and simplify the layout of the beauty device; on the other hand, since the main body 9 integrates the liquid storage chamber 6 and the liquid outlet channel 7 together, it is only necessary to install the main body 9 on the beauty device body 1, and components such as the opening and closing valve 4, the liquid storage chamber 6 and the liquid outlet channel 7 can be simultaneously installed on the beauty device body 1, which facilitates the manufacturing and installation of components such as the opening and closing valve 4, the liquid storage chamber 6 and the liquid outlet channel 7.

[0085] Understandably, there are multiple ways to set up the beauty head 8. As mentioned earlier, the beauty head 8 can be directly set on the beauty device body 1. In this case, the beauty head 8 is directly and fixedly installed on the beauty device body 1, and the beauty device body 1 provides fixed support for the beauty head 8.

[0086] Alternatively, in some embodiments, the beauty head 8 can be connected to the main body 9. In this case, by setting the main body 9 on the beauty device body 1, the beauty head 8 is indirectly set on the beauty device body 1. The difference between this setting method and directly setting the beauty head 8 on the beauty device body 1 is that by connecting the main body 9 and the beauty head 8, the main body 9 and the beauty head 8 form a beauty component that can be integrated for production. The beauty component is easy to manufacture. This embodiment uses a setting method in which the beauty head 8 and the main body 9 are fixed to each other as an example.

[0087] It is understood that no restrictions are placed on the specific combination of the beauty head 8 and the main body 9. Regardless of the setting method of the beauty head 8, as long as any of the above methods are used, they should be included in the scope of alternative means of this solution.

[0088] In addition, the first clearance hole 91 and the second clearance hole 92 are respectively provided through the main body 9. The first clearance hole 91 and the second clearance hole 92 are used to provide space clearance for the hose so that the pressure generated by the drive component 3 can pass through the main body 9 from the outside to the inside and reach the piston 2, and the pressure generated by the control component 5 can pass through the main body 9 from the outside to the inside and reach the opening and closing valve 4, so as to achieve a mutual cooperation effect.

[0089] Reference Figure 4 and Figure 5 In the embodiments of this application, a vibration mechanism 10 is also included, which includes a vibration motor 101 and a vibration connector 102. The vibration motor 101 is disposed on the beauty device body 1, the vibration connector 102 is connected to the output shaft of the vibration motor 101, and the main body 9 is disposed on the vibration connector 102.

[0090] Typically, the vibration motor 101 is fixedly installed inside the beauty device body 1, and the vibration motor 101 is connected to the main body 9 through the vibration connector 102.

[0091] Based on the above configuration, when the beauty head 8 is connected to the main body 9, the vibration mechanism 10 can drive the beauty head 8 to pat the skin. On the one hand, it can have a massage effect and further open the absorption channels; on the other hand, when the beauty head 8 is equipped with microneedles, it can also achieve an automatic puncture effect, and the absorption efficiency of the essence is significantly improved.

[0092] However, it should be noted that at this time, the main body 9 is connected to the vibration motor 101 through the vibration connector 102, which is equivalent to indirectly setting the main body 9 on the beauty instrument body 1 through the vibration mechanism 10. On this basis, the main body 9 can be fixedly connected to the vibration mechanism 10, or it can be detachably connected to the vibration mechanism 10. Here, whether the main body 9 is directly set on the beauty instrument body 1 or indirectly set on the beauty instrument body 1, or adopts a fixed setting method or a detachable setting method, the quantitative liquid dispensing effect can be achieved. The above installation method should be included in the scope of interpretation of this application.

[0093] Continue to refer to Figure 4 and Figure 5 In some embodiments, the vibration connector 102 includes a mounting sleeve 105 for inserting and removing the main body 9. The vibration connector 102 is provided with a first connecting portion 103. The driving component 3 cooperates with the piston 2 through the first connecting portion 103 and the first clearance hole 91. The vibration connector 102 is provided with a second connecting portion 104. The control component 5 cooperates with the opening and closing valve 4 through the second connecting portion 104 and the second clearance hole 92.

[0094] In some embodiments, the mounting sleeve 105 has a long sleeve-shaped structure, which is hollow inside and open at one end. The open end of the mounting sleeve 105 is used for the main body 9 to be inserted and removed. At this time, the main body 9 can be disassembled relative to the mounting sleeve 105.

[0095] Reference Figure 4 and combined Figure 3 To ensure unobstructed airflow even after disassembly and replacement of the main component 9, the first connecting portion 103 and the second connecting portion 104 are used to maintain the air passage. Specifically, both the first connecting portion 103 and the second connecting portion 104 are cylindrical structures, hollow inside, and open at both ends. The first connecting portion 103 and the second connecting portion 104 are integrally connected to the mounting sleeve 105, and their ends extend to the inner and outer sides of the mounting sleeve 105, respectively.

[0096] On one hand, the first connecting part 103 is used to connect the first pipe 32 and the liquid storage chamber 6 to the driving component 3 in the detachable state of the main body 9. Specifically, the main body 9 is recessed with a first insertion groove, and the first clearance hole 91 is located at the bottom of the first insertion groove and communicates with the liquid storage chamber 6. At the same time, the first pipe 32 is connected to the end of the first connecting part 103 located outside the mounting sleeve 105. In addition, the end of the first connecting part 103 located inside the mounting sleeve 105 is engaged with the first insertion groove. At this time, when the main body 9 is inserted into the mounting sleeve 105, the first connecting part 103 can be inserted into the first insertion groove simultaneously, so that the first gas source 31 can be connected to the liquid storage chamber 6 through the first pipe 32.

[0097] On the other hand, the second connecting part 104 is used to connect the third pipe 53 and the on / off valve 4 to the control component 5 in the detachable state of the main body 9. Specifically, the main body 9 is recessed with a second insertion groove, the second clearance hole 92 is located at the bottom of the second insertion groove, and the third pipe 53 includes two separate sections, which are defined as the first section and the second section respectively; wherein, the two ends of the first section are respectively connected to the output end of the control component 5 and the end of the second connecting part 104 located outside the mounting sleeve 105.

[0098] In addition, the second section of the third pipe 53 is located inside the main body 9, and one end of the second section is connected to the inner wall of the main body 9 and communicates with the second clearance hole 92. The other end of the second section is connected to the on / off valve 4. At this time, during the process of inserting the main body 9 into the mounting sleeve 105, the second connecting part 104 can be inserted into the second insertion slot. The first section of the third pipe 53 is spliced ​​and combined with the second section so that the control component 5 can be connected to the on / off valve 4 through the third pipe 53.

[0099] Based on the above configuration, the mounting sleeve 105 provides a plug-in positioning support for the main body 9, enabling the main body 9 to be detachable. In addition, under the action of the first connecting part 103 and the second connecting part 104, the driving component 3 can cooperate with the liquid storage chamber 6, and the control component 5 can cooperate with the opening and closing valve 4.

[0100] Furthermore, in order to allow the main body 9 to be detachably mounted on the vibration mechanism 10, a first fastener 11 can be provided on the mounting sleeve 105, and a second fastener 12 can be provided on the main body 9. Under the action of the first fastener 11 and the second fastener 12 being movably fastened, the main body 9 can be disassembled and assembled relative to the vibration mechanism 10, so that the beauty components can be replaced regularly and a hygienic skin care environment can be maintained.

[0101] In some embodiments, the first snap-fit ​​11 is a spring snap structure, and the corresponding second snap-fit ​​12 is a snap-fit ​​groove structure. The spring snap and the snap-fit ​​groove can be movably snapped together to achieve a quick assembly effect. In other embodiments, the first snap-fit ​​11 can be a snap-fit ​​groove structure, and the corresponding second snap-fit ​​12 can be a spring snap structure. The specific structure of the first snap-fit ​​11 and the second snap-fit ​​12 is not limited here. As long as the detachable connection between the mounting sleeve 105 and the main body 9 can be achieved, they should be included in the equivalent interpretation scope of this application.

[0102] Furthermore, it also includes a care head 13, which is disposed on the beauty device body 1. The care head 13 includes an electrode care head 13 or an ultrasonic transducer care head 13, used for skin care.

[0103] In some embodiments, the care head 13 may be installed at one end of the beauty device body 1. In other embodiments, the care head 13 may also be located on one side of the beauty device body 1. There are no restrictions on the installation position of the care head 13.

[0104] Based on this, the setting method of the care head 13 can be selected according to actual needs. For example, in one embodiment, the electrode care head 13 or the ultrasonic transducer care head 13 can be set separately. In another embodiment, the electric care head 13 and the ultrasonic transducer care head 13 can be set on the beauty instrument body 1 at the same time. There are no restrictions on the specific type and number of care heads 13.

[0105] It should be explained that the electrode care head 13 refers to a care head 13 with electrode elements, which can further penetrate deep into the skin, expand the care area, and promote skin absorption; while the ultrasonic transducer care head 13 refers to a care head 13 with an ultrasonic transducer. An ultrasonic transducer is a device that converts electromagnetic energy into mechanical energy (vibration), usually made of piezoelectric ceramics or other magnetostrictive materials. By transmitting vibration to the skin, it achieves a tapping absorption effect, which can also play a role in promoting penetration, thereby optimizing the skin care effect.

[0106] Furthermore, when the treatment head 13 is an electrode treatment head 13, the discharge frequency of the electrode treatment head 13 is 2.5kHz-3.5kHz. When the discharge frequency of the electrode treatment head 13 is less than 2.5kHz, it may result in insufficient discharge energy, preventing the current from reaching the dermis and affecting absorption. Conversely, when the discharge frequency of the electrode treatment head 13 is greater than 3.5kHz, it may result in excessively high discharge energy, leading to skin redness, allergies, and other adverse reactions. Therefore, limiting the discharge frequency of the electrode treatment head 13 to between 2.5kHz and 3.5kHz allows for better deep skincare efficacy while further protecting the skin and optimizing the user experience.

[0107] For example, the discharge frequency of the electrode care head 13 can be specifically set to 2.5 kHz, 2.6 kHz, 2.7 kHz, 2.8 kHz, 2.9 kHz, 3.0 kHz, 3.1 kHz, 3.2 kHz, 3.3 kHz, 3.4 kHz or 3.5 kHz. Alternatively, the range of the discharge frequency can be set between any two of the above parameter values. This embodiment does not limit the specific parameters of the discharge frequency.

[0108] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
