[0002] In the field of beauty and skincare, achieving deep hydration and nutrient delivery to the skin is a key requirement for improving skin quality. Traditional skincare methods directly inject active ingredients such as hyaluronic acid into the dermis, which has significant effects and is favored and loved by consumers.

[0003] Currently, conventional beauty devices mainly consist of the device itself and an air pressure system. The essence is transferred to the device itself, and air pressure is introduced through the air pressure system to atomize the essence and apply it to the user's skin. However, current beauty devices still have many shortcomings. For example, it is often difficult to control the amount of essence dispensed during the dispensing process, resulting in uneven application and affecting the skincare effect. 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

[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 liquid dispensing beauty device, including a beauty device body 1, a piston 2, and a motor assembly 3.

[0049] The beauty device body 1 has a liquid storage chamber 4 and a liquid outlet channel 5. The liquid storage chamber 4 and the liquid outlet channel 5 are connected. The piston 2 is movably disposed in the liquid storage chamber 4. The motor assembly 3 is connected to the piston 2. The motor assembly 3 is used to drive the piston 2 to move quantitatively, thereby pushing the essence quantitatively to the liquid outlet channel 5. The liquid outlet channel 5 is used to guide the essence to the outside.

[0050] Specifically, the beauty device body 1 is mainly used to provide installation positions for various components, such as the motor assembly 3 and the piston 2 can be set on the beauty device body 1.

[0051] Typically, the reservoir 4 is used to store the essence, and the outlet channel 5 can be a flexible tube structure in one embodiment, with the channel inside the flexible tube forming the outlet channel 5. In another embodiment, the outlet channel 5 can also be obtained by setting holes or grooves on the beauty device body 1. The outlet channel 5 provided in this embodiment is set as a hole structure as an example. Here, the specific setting method of the outlet channel 5 is not limited.

[0052] Based on this, piston 2 can slide back and forth in the liquid storage chamber 4, and by driving piston 2 to move, the volume of liquid storage chamber 4 can be changed. In this process, the movement of piston 2 is mainly controlled by motor assembly 3. Motor assembly 3 is connected to piston 2 and has precise motion output control function. Therefore, motor assembly 3 is used to drive piston 2 to move quantitatively. According to the actual movement amount required, the movement distance of piston 2 can be changed, thereby making piston 2 quantitatively squeeze liquid storage chamber 4 and quantitatively push essence to liquid outlet channel 5. Then, liquid outlet channel 5 can guide essence to the outside.

[0053] In this embodiment, by adopting the above-described settings, the motor assembly 3 precisely outputs a reciprocating motion, thereby precisely pushing the piston 2 to squeeze the liquid storage chamber 4. The essence then enters the liquid outlet channel 5 and finally flows out quantitatively to the outside of the beauty device body 1, thus realizing the quantitative liquid dispensing function.

[0054] Reference Figure 2In one optional embodiment, the motor assembly 3 includes a first stepper motor 31, a lead screw 32, and a push rod 33. The lead screw 32 is connected to the output shaft of the first stepper motor 31, and the lead screw 32 is connected to the push rod 33. The push rod 33 is connected to the piston 2. The lead screw 32 is used to drive the push rod 33 to reciprocate, so that the push rod 33 pushes the piston 2 to move.

[0055] The first stepper motor 31 is mounted on the beauty device body 1. This mounting method can be understood as either directly mounted on the beauty device body 1 or indirectly mounted on it through a centrally located component; no specific limitations are specified here. The first stepper motor 31 converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by one 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.

[0056] Based on this, the lead screw 32 is rotatably mounted on the beauty device body 1. It can be understood that the mounting method here can be either directly rotatably mounted on the beauty device body 1 or indirectly rotatably mounted on the beauty device body 1 through a centrally mounted component. There are no restrictions on the specific installation method of the lead screw 32, and the length direction of the lead screw 32 is parallel to the displacement direction of the piston 2.

[0057] In addition, the push rod 33 has a rod body and a boss connected to the rod body. The boss has a threaded hole, and the lead screw 32 is threaded into the threaded hole. The push rod 33 is slidably disposed on the beauty device body 1 to achieve movement limit. Generally, the specific installation method of the push rod 33 can be to be directly slidably disposed on the beauty device body 1 or indirectly slidably disposed on the beauty device body 1 through a centrally disposed component. The specific sliding method of the push rod 33 is not limited here. Based on this, the sliding direction of the push rod 33 is consistent with the sliding direction of the piston 2, and the rod body abuts against the piston 2.

[0058] Based on the above configuration, during the rotation of the lead screw 32, the boss part can be displaced, and the boss part drives the rod part to move synchronously. Since the rod part abuts against the piston 2, it can push the piston 2 to squeeze the liquid storage chamber 4, thereby achieving the liquid dispensing effect. The above actions are precise and easy to control, and can quickly and conveniently achieve the quantitative liquid dispensing effect.

[0059] Reference Figure 3 In another alternative embodiment, the motor assembly 3 includes a second stepper motor 34, a gear 35, and a rack 36. The gear 35 is connected to the output shaft of the second stepper motor 34, and the rack 36 is slidably disposed on the beauty device body 1, meshing with the gear 35, and is connected to the piston 2.

[0060] The specific structure and configuration of the second stepper motor 34 will not be elaborated here. Based on this, the gear 35 and the output shaft of the second stepper motor 34 are fixed to each other, and the second stepper motor 34 can drive the gear 35 to rotate precisely within a specific angle range.

[0061] In addition, the rack 36 can be installed by sliding it directly on the beauty device body 1 or by sliding it indirectly on the beauty device body 1 through a centrally located component. There are no restrictions on the specific sliding method of the rack 36. Based on this, the sliding direction of the rack 36 is consistent with the displacement direction of the piston 2, and one end of the rack 36 abuts against the piston 2.

[0062] Based on the above settings, during the rotation of gear 35, rack 36 can be driven to move linearly. Since rack 36 abuts against piston 2, rack 36 can further push piston 2 to squeeze liquid storage chamber 4 during the movement, thus achieving liquid discharge. The above actions are precise and easy to control, and can quickly and conveniently achieve quantitative liquid discharge.

[0063] Reference Figure 2 and Figure 3 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 6. In some embodiments, the beauty head 6 has an outlet hole 61 that communicates with the outlet channel 5. Based on the above configuration, the beauty head 6 can be directly set at one end of the beauty device body 1, and the essence can flow to the beauty head 6 through the outlet hole 61. In actual use, the beauty head 6 can be attached to the skin care area, and the location of the beauty head 6 is the skin care position of the beauty device, achieving a precise application effect.

[0064] In other embodiments, the beauty head 6 has a liquid outlet hole 61 that communicates with the liquid outlet channel 5, and the beauty head 6 is also provided with microneedles and / or electrodes, the microneedles and / or electrodes and the liquid outlet hole 61 being located on the same surface of the beauty head 6.

[0065] It should be explained that when the beauty head 6 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.

[0066] When the beauty head 6 is equipped with microneedles, it 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.

[0067] When the beauty head 6 is equipped with both microneedles and electrodes, multiple combined penetration-enhancing effects can be achieved, further optimizing and improving the skincare results.

[0068] In some possible embodiments of this application, a main body component 7 is also included. (See reference...) Figure 2 and Figure 3 The liquid storage chamber 4 and the liquid outlet channel 5 are provided on the main body 7. The main body 7 is provided with a first clearance hole 71, which is used to connect the power supply assembly 3 and the piston 2.

[0069] Specifically, the main body 7 has a shell structure and is hollow inside. The liquid storage chamber 4 and the liquid outlet channel 5 are disposed in the main body 7 and located inside the main body 7. The main body 7 can integrate the liquid outlet channel 5 and the liquid storage chamber 4. Specifically, in this embodiment, the main body 7 is provided with a partition structure, which encloses a part of the main body 7 to form the liquid storage chamber 4, and one end of the partition is connected to the liquid outlet channel 5.

[0070] Based on the above configuration, on the one hand, by integrating the liquid storage chamber 4 and the liquid outlet channel 5 into the main body 7, 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 7 integrates the liquid storage chamber 4 and the liquid outlet channel 5 together, it is only necessary to install the main body 7 on the beauty device body 1 to simultaneously set the liquid storage chamber 4 and the liquid outlet channel 5 on the beauty device body 1, which facilitates the manufacturing and installation of components such as the liquid storage chamber 4 and the liquid outlet channel 5.

[0071] Based on this, the first clearance hole 71 is connected to the liquid storage chamber 4. The first clearance hole 71 is used to allow the rack 36 or push rod 33 to extend into the liquid storage chamber 4 from the outside through the first clearance hole 71. The first clearance hole 71 plays a clearance role here, thereby connecting the motor assembly 3 and the piston 2, which can meet the action requirements of pushing out liquid.

[0072] Understandably, there are multiple ways to set up the beauty head 6. As mentioned earlier, the beauty head 6 can be directly set on the beauty device body 1. In this case, the beauty head 6 is directly and fixedly installed on the beauty device body 1, and the beauty device body 1 provides fixed support for the beauty head 6.

[0073] In another configuration of the beauty head 6, the beauty head 6 is connected to the main body 7. In this case, the main body 7 is mounted on the beauty device body 1, thus indirectly mounting the beauty head 6 onto the beauty device body 1. The difference between this configuration and directly mounting the beauty head 6 on the beauty device body 1 is that by connecting the main body 7 and the beauty head 6, the main body 7 and the beauty head 6 form a beauty component that can be integrated for production, facilitating manufacturing. This embodiment uses a configuration where the beauty head 6 and the main body 7 are mutually fixed as an example.

[0074] It is understood that no restrictions are placed on the specific combination of the beauty head 6 and the main body 7. Regardless of the setting method of the beauty head 6, as long as any of the above methods are used, they should be included in the scope of alternative means of this solution.

[0075] Optionally, the main body 7 can also be set in various ways compared to the beauty device body 1. In some embodiments, the main body 7 is fixedly set inside the beauty device body 1, which can ensure that the main body 7 and the beauty head 6 can work stably and are not easy to fall off.

[0076] In some embodiments, a fastener can be provided between the beauty device body 1 and the main component 7. This allows the main component 7 to be detachably mounted on the beauty device body 1 via the fastener. In this case, the main component 7 can not only be stably mounted, but the entire beauty assembly can also be detached from the beauty device body 1. This facilitates the periodic replacement of the beauty assembly, maintaining a clean and hygienic operating condition for the beauty device. Alternatively, the main component 7 can be indirectly mounted on the beauty device body 1 via other components; the specific mounting method of the main component 7 is not limited here.

[0077] Reference Figure 4 In some embodiments, the beauty device further includes a vibration mechanism 8, which is connected to the main body 7. The motor assembly 3 is disposed on the vibration mechanism 8, and the beauty head 6 is connected to the main body 7. The vibration mechanism 8 is used to drive the main body 7 and the motor assembly 3 to vibrate back and forth simultaneously, so as to drive the beauty head 6 to vibrate back and forth.

[0078] Specifically, the vibration mechanism 8 is set in the beauty device body 1 and connected to the beauty head 6. The vibration mechanism 8 can drive the beauty head 6 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 6 equipped with microneedles, it can also achieve the effect of automatically piercing the stratum corneum, and the absorption efficiency of the essence is significantly improved.

[0079] It should be noted that the connection between the main body 7 and the vibration mechanism 8 is equivalent to indirectly mounting the main body 7 on the beauty device body 1 through the vibration mechanism 8. Based on this, the main body 7 can be fixedly connected to the vibration mechanism 8, or it can be detachably connected to the vibration mechanism 8. Therefore, regardless of whether the main body 7 is directly mounted on the beauty device body 1 or indirectly mounted on the beauty device body 1, or whether it adopts a fixed mounting method or a detachable mounting method, the above-mentioned installation methods should be included in the scope of interpretation of this application. In the following embodiments, the main body 7 adopts a detachable mounting method on the vibration mechanism 8 as an example.

[0080] Reference Figure 4 and Figure 5In some embodiments, the vibration mechanism 8 includes a vibration motor 81 and a vibration connector 82, wherein the vibration motor 81 is disposed on the beauty device body 1, the vibration connector 82 is connected to the output shaft of the vibration motor 81, and the main body 7 and the motor assembly 3 are disposed on the vibration connector 82.

[0081] Specifically, the vibration motor 81 is usually fixedly installed inside the beauty device body 1, and the vibration motor 81 is connected to the main body 7 through the vibration connector 82.

[0082] Based on the above technical solution, the vibration motor 81 can output stable vibration and transmit the vibration force to the main body 7 through the vibration connector 82, thus realizing the vibration care function of the beauty head 6.

[0083] When the motor assembly 3 is installed on the vibration connector 82, the installation method of the motor assembly 3 is different in different embodiments.

[0084] Among them, reference Figure 2 In some embodiments, when the motor assembly 3 includes a first stepper motor 31, a lead screw 32, and a push rod 33, the first stepper motor 31 is fixedly installed on the vibration connector 82, the lead screw 32 is rotatably disposed on the vibration connector 82 and located between the piston 2 and the first stepper motor 31, and the push rod 33 is slidably disposed on the vibration connector 82 along the extension direction of the lead screw 32.

[0085] Specifically, an extension platform 821 can be provided on one side of the vibration connector 82. The first stepper motor 31 can be fixedly mounted on the extension platform 821, and a bearing seat can be provided on the extension platform 821. The lead screw 32 is rotatably mounted on the bearing seat. In addition, a slide groove is provided on the extension platform 821. At this time, a sliding part with a shape that matches the contour of the slide groove can be provided on the boss. By sliding the sliding part into the slide groove, the sliding installation of the push rod 33 can be realized.

[0086] In other embodiments, reference is made to Figure 3 When the motor assembly 3 includes a second stepper motor 34, a gear 35 and a rack 36, the second stepper motor 34 is fixedly mounted on the vibration connector 82, and the rack 36 is slidably mounted on the vibration connector 82 and located between the piston 2 and the second stepper motor 34.

[0087] Correspondingly, in order to meet the assembly requirements of each component in the motor assembly 3, an extension platform 821 can also be set on one side of the vibration connector 82. At this time, the second stepper motor 34 can be fixedly set on the extension platform 821, and a slide groove can be set on the extension platform 821, in which the rack 36 is slidably installed.

[0088] It is understood that no restrictions are placed on the specific installation method of the motor assembly 3. In practical applications, the specific setting method of the motor assembly 3 can be adapted according to actual needs. Regardless of the specific installation method, as long as the motor assembly 3 is set on the vibration connector 82, it should be included in the scope of interpretation of this application.

[0089] Continue to refer to Figure 4 and Figure 5 In some embodiments, the vibration connector 82 includes a mounting sleeve 823 for inserting and removing the main body 7, and the mounting sleeve 823 is provided with a second clearance hole 822. The motor assembly 3 is connected to the piston 2 through the first clearance hole 71 and the second clearance hole 822.

[0090] In some embodiments, the mounting sleeve 823 has a long sleeve-shaped structure with a hollow interior and an open end. The main body 7 is plugged into the mounting sleeve 823 through the open end of the mounting sleeve 823. It can be understood that when the main body 7 is inserted into the mounting sleeve 823, the beauty head 6 is exposed at the open end of the mounting sleeve 823. The second clearance hole 822 is provided at the other end of the mounting sleeve 823. The second clearance hole 822 is connected to the first clearance hole 71. The motor assembly 3 is connected to the piston 2 through the first clearance hole 71 and the second clearance hole 822, so that the second clearance hole 822 plays a clearance role, so that the motor assembly 3 can act on the piston to realize liquid discharge.

[0091] In some embodiments, in order to enable the main body 7 to be detachably mounted on the vibration mechanism 8, a first fastening position 9 is provided on the mounting sleeve 823, and a second fastening position 10 is provided on the main body 7 to be movably fastened to the first fastening position.

[0092] Specifically, the first fastener 9 is located on the inner wall or open end of the mounting sleeve 823, and the second fastener 10 is located on the outer peripheral wall of the main body 7. Under the action of the first fastener 9 and the second fastener 10 in a movable fastening manner, the main body 7 can be disassembled and assembled relative to the vibration mechanism 8, so that the beauty components can be replaced regularly and a hygienic skin care environment can be maintained.

[0093] In other embodiments, the mounting sleeve 823 may be a claw-shaped structure. In this case, the mounting sleeve 823 may include multiple claw fingers, the main body 7 may be fixed by the multiple claw fingers, and the second clearance hole 823 may be the gap between the claw fingers.

[0094] Furthermore, the claw fingers of the mounting sleeve 823 are provided with a first fastening position 9, and the main body 8 is provided with a second fastening position 10 that is movably fastened to the first fastening position 9.

[0095] In some embodiments, the first snap-fit ​​9 is a spring-loaded snap-fit ​​structure, and the corresponding second snap-fit ​​10 is a snap-fit ​​groove structure. The spring-loaded snap-fit ​​and the snap-fit ​​groove can be movably snapped together to achieve a quick assembly effect. In other embodiments, the first snap-fit ​​9 can be a snap-fit ​​groove structure, and the corresponding second snap-fit ​​10 can be a spring-loaded snap-fit ​​structure. The specific structure of the first snap-fit ​​9 and the second snap-fit ​​10 is not limited here. As long as the detachable connection between the mounting sleeve 823 and the main body 7 can be achieved, they should be included in the equivalent interpretation scope of this application.

[0096] In some embodiments, replay Figure 1 It also includes a care head 11, which is set on the beauty device body 1. The care head 11 includes an electrode care head 11 or an ultrasonic transducer care head 11, which is used for skin care.

[0097] In some embodiments, the care head 11 may be installed at one end of the beauty device body 1. In other embodiments, the care head 11 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 11.

[0098] Based on this, the electrode care can be configured according to actual needs. For example, in one embodiment, the electrode care head 11 or the ultrasonic transducer care head 11 can be set separately. In another embodiment, the electrode care head 11 and the ultrasonic transducer care head 11 can be set on the beauty device body 1 at the same time. There are no restrictions on the specific type and number of care heads 11.

[0099] It should be explained that the electrode care head 11 refers to a care head 11 with electrode elements, which can further penetrate deeper into the skin, expand the care area, and promote skin absorption; while the ultrasonic transducer care head 11 refers to a care head 11 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.

[0100] Furthermore, when the treatment head 11 is an electrode treatment head 11, the discharge frequency of the electrode treatment head 11 is 2.5kHz-3.5kHz. When the discharge frequency of the electrode treatment head 11 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 11 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 11 to between 2.5kHz and 3.5kHz allows for better deep skincare efficacy while further protecting the skin and optimizing the user experience.

[0101] For example, the discharge frequency of the electrode care head 11 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.

[0102] 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.
