Abstract
Description
Technical Field
[0001] This invention relates to the technical field of beauty devices, and more particularly to a beauty device. Background Technology
[0002] With the development of beauty instrument technology, beauty devices combining negative pressure adsorption and serum delivery have gradually become mainstream in the market. In the background technology, one type of beauty device integrates skin adsorption and serum delivery through the cooperation of a negative pressure mechanism and a negative pressure channel. Its core structure includes the beauty device body, a negative pressure chamber, a reservoir, a beauty head, a negative pressure channel, and a negative pressure mechanism. The negative pressure channel sequentially connects the reservoir, the negative pressure chamber, and the negative pressure mechanism. The negative pressure mechanism creates a negative pressure area within the negative pressure chamber to adsorb the skin by suction, while simultaneously drawing the serum from the reservoir to the beauty head and applying it to the skin. Although the above solution integrates negative pressure adsorption and serum delivery, the following problems remain to be solved in practical applications:
[0003] (1) Insufficient negative pressure stability leads to low precision in serum application. Background technology's negative pressure mechanisms must simultaneously fulfill the dual functions of "skin adsorption" and "serum extraction," sharing the same negative pressure channel. Due to the natural unevenness of the human skin surface (such as the contour differences of the nose, cheeks, and perianal area), the sealing between the negative pressure cavity and the skin is easily affected: in raised areas such as the bridge of the nose, gaps may form due to insufficient fit; in flat areas such as the cheeks, uneven contact pressure may cause fluctuations in local negative pressure values. This instability directly causes changes in air pressure within the negative pressure channel, making it difficult to precisely control the rate and dosage of serum extraction from the reservoir. This can lead to serum waste or, in severe cases, skin irritation due to excessive local dosage.
[0004] (2) Increased structural complexity and cost. To alleviate the problem of unstable negative pressure, additional pressure sensors, multi-way valves, and control components are required to dynamically adjust the start and stop of the negative pressure pump and solenoid valve by detecting the air pressure in the negative pressure channel in real time. These detection and feedback components not only increase the hardware cost of the product, but also increase the complexity of circuit design and assembly difficulty, which is not conducive to miniaturization and low-cost mass production.
[0005] (3) Interference issues arise from the coupling of negative pressure and serum delivery. The negative pressure mechanism needs to simultaneously drive "skin adsorption" and "serum extraction," and the air pressure requirements for the two are inherently contradictory: adsorption of the skin requires a higher negative pressure to ensure stable adhesion, while extraction of the serum requires a lower negative pressure to avoid excessive flow rate. This coupled control makes it difficult for the system to achieve optimal performance under both conditions. For example, increasing the negative pressure to enhance adsorption may result in excessive serum extraction; decreasing the negative pressure to reduce serum flow rate may lead to weak skin adsorption.
[0006] (4) Safety hazards and hygiene issues related to backflow in the negative pressure channel. The suction effect of the negative pressure channel may cause a momentary negative pressure to form in the liquid storage chamber. When the negative pressure mechanism stops working or the air pressure fluctuates, the essence in the liquid storage chamber may flow back into the negative pressure channel due to the reverse pressure difference, and may even seep into core components such as the negative pressure pump, causing equipment failure. During the extraction of essence, the negative pressure channel will inevitably suck in some residual essence that has not been absorbed by the skin, as well as impurities such as keratin debris and oil on the skin surface. Since the essence is rich in nutrients, residual liquid and impurities are prone to bacterial growth or oxidation and deterioration in the negative pressure channel. Long-term use may lead to channel blockage, odor, and even backflow of skin contamination through the beauty head, seriously threatening the hygiene and safety and lifespan of the product.
[0007] In summary, the negative pressure beauty devices in the background technology suffer from problems such as low precision, high cost, and poor hygiene. Summary of the Invention
[0008] This invention provides a beauty device that aims to solve the background technical problems caused by the simultaneous adsorption of essence by the negative pressure mechanism during the adsorption of skin.
[0009] This invention provides the following technical solution: a beauty device for skin care, comprising a beauty device body; a negative pressure cavity disposed at one end of the beauty device body and having a negative pressure suction port for forming a negative pressure area for adsorbing skin; a beauty head disposed within the negative pressure cavity, the beauty head having a microneedle chip and a liquid outlet port; the liquid outlet port being connected to a reservoir for storing essence via a fluid pipe; a negative pressure mechanism connected to the negative pressure cavity, one end of the negative pressure suction channel forming the negative pressure suction port, the negative pressure mechanism being used to evacuate air from the negative pressure suction channel to form the negative pressure area within the negative pressure cavity; and an air blowing module connected to the reservoir via an air blowing channel; the air blowing module is configured to: in a first state, generate intermittent positive pressure to transport the essence in the reservoir through the fluid pipe to the liquid outlet port and apply it to the skin via the microneedle chip; in a second state, maintain the reservoir in a negative pressure state to resist the suction effect of the negative pressure within the negative pressure cavity on the essence.
[0010] This invention has the following technical advantages: By using a structure where a negative pressure mechanism independently adsorbs the skin and an air blowing module independently delivers the essence, this invention specifically solves the problems of low precision, contamination, and complex structure caused by the coupling of negative pressure and essence delivery in the prior art. The specific beneficial effects are as follows:
[0011] (1) The negative pressure mechanism in this solution draws air from the negative pressure chamber through a negative pressure suction channel to create a negative pressure area that adheres to the skin. Its function is to tightly adhere to the skin, making the skin fit closely to the liquid outlet of the beauty head to form a sealed negative pressure area. The blowing module is independently connected to the liquid storage chamber through a blowing air channel, responsible for delivering the essence, and is not directly coupled to the negative pressure mechanism. The negative pressure provides negative pressure to adhere to the skin, and the blowing module delivers the essence, eliminating the problem of uneven liquid dispensing caused by negative pressure coupling interference in the background technology, and significantly improving the accuracy of essence application.
[0012] (2) The first state is intermittent positive pressure delivery, which realizes quantitative control of the essence and solves the problem of inaccurate negative pressure suction. In the first state of this solution, the blowing module generates intermittent positive pressure pulses. By controlling the number and intensity of the pulses, the amount of essence delivered in a single delivery can be precisely controlled, avoiding the fluctuation of delivery volume caused by "continuous negative pressure suction" in the background technology, realizing quantitative and controllable delivery of essence, and preventing excessive essence from being drawn into the negative pressure pipeline.
[0013] Furthermore, the intermittent positive pressure in the first state prevents siphoning through physical flow interruption, reducing the risk of contamination in the negative pressure channel from the source. Due to the continuous suction of the negative pressure mechanism, a continuous negative pressure is created on the serum, easily triggering a siphon effect (serum is continuously drawn into the negative pressure channel), leading to fermentation and contamination from residual liquid and skin debris within the channel. This solution's intermittent positive pressure in the first state has a "pulse-pause" characteristic, creating a short pause between two positive pressure pushes. During this pause, the elastic pipe of the blowing module closes due to elastic recovery, temporarily isolating the serum in the fluid pipe from the reservoir (physical flow interruption). This breaks the continuous effect of negative pressure on the serum, preventing the formation of a stable siphon path, reducing serum residue in the negative pressure channel, and lowering the hygiene risk of fermentation and contamination caused by background residual liquid being drawn into the negative pressure channel.
[0014] (4) Second state negative pressure lock, actively resisting negative pressure suction and preventing essence from flowing out. In the second state of this solution, the air blowing module maintains the negative pressure in the liquid storage chamber, forming a pressure balance with the negative pressure area of the negative pressure chamber, actively resisting the suction trend caused by negative pressure fluctuations, ensuring that the essence is not sucked into the negative pressure channel, effectively solving the problem of "essence flowing back into the negative pressure channel" in the background technology, and improving the safety and service life of the product.
[0015] (5) Simplified structure and reduced cost: This solution uses the design of "independent control of negative pressure mechanism and air blowing module" to eliminate the need for complex adjustment components in the background technology. The hardware structure is simplified, the assembly process is reduced, the production cost is significantly reduced, and the product market competitiveness is enhanced.
[0016] Furthermore, the air-blowing module includes an annular base, an elastic pipe surrounding the annular base, and a drive assembly; one end of the elastic pipe is connected to the atmosphere, and the other end is connected to the liquid storage chamber through the air-blowing passage; the drive assembly includes a motor and a rotating head connected to the output shaft of the motor; the rotating head is located at the center of the annular base, and its outer circumferential surface has a protrusion for pressing the elastic pipe. The beneficial effect of these features is that when the protrusion is not rotating, it statically presses the elastic pipe, creating a seal and maintaining a negative pressure state in the liquid storage chamber, achieving the second state. When the protrusion rotates, the elastic pipe is rotated and pressed, and the gas inside the elastic pipe is intermittently pushed into the liquid storage chamber, thus generating intermittent positive pressure.
[0017] Furthermore, at least two protrusions are spaced circumferentially along the rotating head. The rotating head is configured such that, when rotated under the drive of the motor, the protrusions alternately compress the elastic channel to generate intermittent positive pressure through the elastic recovery of the elastic channel. The beneficial effect of this feature is that, by having at least two protrusions alternately compress the elastic channel, the number of positive pressure pulses can be flexibly controlled by adjusting the motor speed, adapting to different skin types.
[0018] Furthermore, it also includes an insertion platform located on the main body of the beauty device; the liquid storage chamber has a bottle structure, and the cap end of the bottle body has an insertion part adapted to the insertion platform; the insertion platform has a conical protrusion, and the outer peripheral surface of the conical protrusion has two spaced cuts. The beneficial effect of the above features is that the conical surface design of the conical protrusion can adapt to the slight dimensional error of the bottle body insertion part, automatically aligning with the cuts for quick positioning during insertion, and the two spaced cuts are reserved for the air and liquid paths respectively, avoiding misalignment and leakage of the air and liquid pipelines during insertion.
[0019] Furthermore, one of the cuts of the conical protrusion has a first hole at its bottom, which communicates with the blowing module through the blowing air passage; when the insertion part of the bottle body is inserted into the conical protrusion, the first hole communicates with the interior of the bottle body; the other cut of the conical protrusion has a second hole at its end, which communicates with the liquid outlet port through the fluid pipe; when the insertion part of the bottle body is inserted into the conical protrusion, the second hole communicates with the interior of the bottle body. The beneficial effects of these features are: the first hole (air passage) and the second hole (liquid passage) are physically isolated; the first hole and the second hole are located at the ends of the cuts, preventing the bottle cap from pressing on the cone during insertion, thus avoiding displacement or shape deformation; the diameter of the first hole and the second hole affects accuracy.
[0020] Furthermore, the negative pressure suction channel is equipped with a three-way connector; the first port of the three-way connector is connected to the negative pressure mechanism, the second port is connected to the negative pressure suction port, and the third port is connected to an electronic valve; when the negative pressure mechanism stops suction, the electronic valve opens to connect the negative pressure suction channel to the atmosphere, thus eliminating the negative pressure in the negative pressure chamber. The beneficial effects of these features are: the electronic valve directly connects to the atmosphere, shortening the negative pressure release time, preventing skin redness due to residual negative pressure when the user removes the device, and improving safety.
[0021] Furthermore, it also includes an integrated module; the integrated module internally includes the insertion platform, the liquid storage bottle replacement port, the air blowing channel, the fluid pipeline, and the negative pressure suction channel; the liquid storage bottle replacement port is positioned corresponding to the insertion platform, for inserting or removing the bottle body of the liquid storage chamber; the integrated module has an opening on the side facing the negative pressure chamber, and a connector is provided in the opening; one end of the connector is connected to the beauty head, and the other end is connected to the fluid pipeline and the negative pressure suction channel of the integrated module respectively; the beneficial effects of the above features are: the integrated module integrates the insertion platform, the air-liquid pipeline, and the negative pressure channel, reducing external pipelines and reducing the risk of leakage caused by assembly errors.
[0022] Furthermore, it also includes a vibration module; the vibration module includes a drive motor, an eccentric drive connector, and a connecting shell; the connecting shell is sleeved on the eccentric rotating component and is drively connected to the connecting shell; the integrated module is sleeved in the cavity of the connecting shell, and the connecting shell can be vibratedly installed in the beauty device body; the drive motor drives the eccentric drive connector to rotate eccentrically, so that the connecting shell is axially limited and can vibrate relative to the beauty device body; a buffer ring is provided inside the opening that surrounds the outer periphery of the connector; the opening edge of the connecting shell is folded to form a limiting edge, and when the connecting shell vibrates, there is a gap between the outer periphery of the limiting edge and the inner wall of the beauty device body. The beneficial effects of the above features are as follows: the transmission motor drives the eccentric transmission connector to rotate, and when the eccentric transmission connector rotates, it causes the connecting shell to vibrate up and down, which in turn drives the integrated module to vibrate the beauty head. The microneedle chip can penetrate the stratum corneum more easily during the vibration, promoting the penetration of the essence into the dermis and improving the absorption efficiency. It is especially effective for large molecule essences (such as collagen). The buffer ring absorbs the impact force transmitted by the vibration module and avoids wear caused by rigid collision.
[0023] This invention also includes a method for controlling a beauty device, comprising the following steps:
[0024] S1. Activate the negative pressure mechanism to evacuate the negative pressure suction channel, so that the negative pressure cavity forms a negative pressure area that adsorbs the skin; at this time, the air blowing module is in the second state to maintain the negative pressure state of the liquid storage cavity;
[0025] S2. When at least one of the following conditions is met, control the air blowing module to switch from the second state to the first state: (a) the negative pressure region in the negative pressure chamber has been formed for a preset time t1; (b) the negative pressure value in the negative pressure suction channel has been detected to have reached a preset negative pressure value P1; (c) a liquid blowing command triggered by the user has been received.
[0026] S3. When the air blowing module is in the first state, control the air blowing module to generate intermittent positive air pressure, and transport the essence in the liquid storage chamber to the liquid outlet port through the fluid pipe.
[0027] S4. When the liquid blowing is completed, control the air blowing module to switch from the first state back to the second state, and control the electronic valve to open, so that the negative pressure suction channel is connected to the atmosphere, and the negative pressure area in the negative pressure cavity is released.
[0028] In addition to the beneficial effects of the product solution, the above method also has the following beneficial effects in terms of its step characteristics: (1) The negative pressure mechanism is activated to form a negative pressure area to adsorb the skin, while the blowing module maintains the second state (the liquid storage chamber is locked under negative pressure). The two are activated synchronously but their functions are independent, which avoids the misdelivery of essence during the negative pressure stage. The blowing module is triggered to switch to the first state by three conditions: "negative pressure stabilization time, negative pressure value reaching the standard, and user command", which ensures that the negative pressure adsorption is stable before delivering the essence, avoiding the waste problem of liquid being discharged before the negative pressure is stable, and improving the controllability of operation.
[0029] (2) By controlling the blowing module to generate intermittent positive pressure pulses, and by adjusting the number of pulses and duration, the total amount of essence delivered in a single session can be precisely quantified, avoiding the "excessive liquid output caused by continuous negative pressure suction" in the background technology, and adapting to the dosage requirements of different skin areas;
[0030] (3) After the liquid blowing is completed, first control the air blowing module to switch back to the second state (liquid storage chamber negative pressure lock), and then open the electronic valve to release the negative pressure of the negative pressure chamber, so as to avoid the airflow drawing back the essence at the moment the negative pressure is released, and eliminate the risk of contamination from "essence flowing back into the negative pressure channel".
[0031] Furthermore, step S3 also includes activating the vibration module (9) to drive the beauty head (31) to vibrate. The beneficial effects of the above features are: the vibration module is activated simultaneously during serum delivery; the vibration promotes skin microcirculation and accelerates the diffusion of the serum within the microneedle channels, increasing absorption speed compared to static dispensing; and the vibration massage can alleviate the slight discomfort of microneedle insertion, improving the user experience.
[0032] Furthermore, in steps S1 and S4, the second state of the air-blowing module is achieved by controlling the rotating head of the drive assembly to stop rotating, and the protrusion of the rotating head compressing the elastic pipe to seal the elastic pipe, thereby maintaining the negative pressure state of the liquid storage chamber. The beneficial effect of the above features is that when the rotating head stops, the protrusion continuously compresses the elastic pipe, maintaining the negative pressure of the liquid storage chamber through a mechanical seal, without requiring additional energy consumption.
[0033] Furthermore, in steps S1 and S4, the second state of the blowing module is achieved by controlling the rotating head of the driving component to rotate in the opposite direction, and alternately squeezing the elastic channel through the protrusion, so that the elastic channel generates a suction force opposite to the blowing direction, thereby maintaining the negative pressure state of the liquid storage chamber. The beneficial effects of the above features are: the suction force generated by the reverse rotation can actively reduce the air pressure in the liquid storage chamber, enhance the ability to resist negative pressure fluctuations, and even if the negative pressure chamber generates instantaneous high pressure due to skin movement, the liquid storage chamber can still lock in the essence through stronger negative pressure.
[0034] Furthermore, in step S3, the start-up time of the vibration module is synchronized with the time when the blowing module switches to the first state, or delayed by 1-500ms. The beneficial effects of these features are: synchronized start-up: vibration assists in the rapid distribution of the essence, suitable for dry skin; delayed start-up (1-500ms): the essence first moistens the skin surface, then vibration promotes penetration, avoiding the stinging sensation caused by direct vibration on dry skin, and meeting the refined needs of sensitive skin.
[0035] Furthermore, in step S4, the conditions for determining the completion of the blowing process include: the blowing module being in the first state for a preset blowing time t2, or the blowing module generating intermittent positive pressure a certain number of times n. The beneficial effects of these features are: by quantitatively controlling the total volume of a single flow (e.g., 0.3-0.5 ml) through a preset time t2 (e.g., 5-10 seconds) or a certain number of times n (e.g., 3-5 pulses), the excessive flow caused by continuous negative pressure aspiration, as described in the background technology, is avoided, adapting to the needs of different skin areas and improving dosage accuracy.

[0048] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0049] Example 1
[0050] Please see Figures 1 to 12This application provides a beauty device for skin care, comprising: a beauty device body 10; a negative pressure cavity 100 disposed at one end of the beauty device body 10 and having a negative pressure suction port 110 for forming a negative pressure area to absorb skin; a beauty head 200 disposed within the negative pressure cavity 100, the beauty head 200 having a microneedle chip 210 and a liquid outlet port 220; the liquid outlet port 220 being connected to a liquid storage chamber 300 for storing essence via a fluid pipe 510; and a negative pressure mechanism 400 connected to the negative pressure cavity 100, one end of the negative pressure suction channel 410 forming the negative pressure suction port 110. The negative pressure mechanism 400 is used to evacuate air from the negative pressure suction channel 410 so that the negative pressure cavity 100 forms the negative pressure area; the blowing module 500 is connected to the liquid storage cavity 300 through the blowing air channel 520; the blowing module 500 is configured to: in a first state, generate intermittent positive air pressure to transport the essence in the liquid storage cavity 300 to the liquid outlet port 220 through the fluid pipe 510 and apply it to the skin through the microneedle chip 210; in a second state, maintain the liquid storage cavity 300 in a negative pressure state to resist the suction effect of the negative pressure in the negative pressure cavity 100 on the essence.
[0051] Specifically, the top of the beauty device body 10 is the beauty head 200, and the beauty device body 10 has a negative pressure chamber 100 at the position of the beauty head 200. The negative pressure chamber 100 is connected to a negative pressure mechanism 400 through a negative pressure suction port 110. When the negative pressure mechanism 400 is working, it evacuates air from the negative pressure chamber 100 through the negative pressure suction port 110, thereby creating a negative pressure state inside the negative pressure chamber 100. In this state, the microneedle chip 210 at the top of the beauty head 200 can closely adhere to and act on the skin. The middle part of the beauty head 200 is the liquid outlet port 220, which is connected to a fluid pipe 510 and forms a communication with the liquid storage chamber 300. The liquid storage chamber 300 is connected to an air blowing channel 520. Airflow from the air blowing channel 520 enters the liquid storage chamber 300, allowing the essence within to be transported via the fluid pipe 510 to the liquid outlet port 220 and act on the microneedle chip 210. This allows the beauty essence on the microneedle chip 210 to adhere closely to the skin when the negative pressure chamber 100 is under negative pressure. In this embodiment, the pipes generating negative pressure and the liquid outlet on the beauty device body 10 have different action paths, independently controlled by the air blowing module 500 and the negative pressure mechanism 400. This allows the system to independently adjust parameters according to the essence delivery requirements and skin absorption requirements, while the negative pressure... Mechanism 400 is specifically designed to maintain the adsorption function of the negative pressure chamber 100. The adsorption force is relatively stable, ensuring stable adsorption across different skin contour areas and avoiding negative pressure fluctuations caused by essence extraction. The air blowing module 500 has different operating states. When the air blowing module 500 is in its first state, the positive air pressure it generates is intermittent. This means that the essence is intermittently delivered to the outlet port 220 via the fluid pipe 510 along with the intermittent positive air pressure. The interval time of the air blowing module 500 can be set according to specific usage requirements, thereby significantly improving the dosage accuracy and uniformity of essence delivery. Simultaneously, the flow rate of the essence located on the microneedle chip 210 can... The system is designed to prevent excessive residue from flowing into the negative pressure chamber 100 and forming contaminants. Furthermore, the intermittent positive pressure in the first state has a "pulse-pause" characteristic, creating a short pause between two positive pressure pushes. Because the elastic channel 540 of the blowing module 500 closes due to elastic recovery, the essence in the fluid channel 510 is temporarily isolated from the reservoir chamber 300, interrupting the continuous effect of negative pressure on the essence, preventing the formation of a stable siphon path, and reducing essence residue or waste in the negative pressure channel. The blowing module 500 also has a second state, in which the reservoir chamber 300 is under negative pressure, meaning the blowing module 500 actively resists negative pressure suction, preventing essence from flowing out.In the second state of this solution, the air blowing module 500 is stationary. In this state, the air blowing module 500 maintains negative pressure in the liquid storage chamber 300. This negative pressure forms a dynamic balance with the negative pressure in the negative pressure suction channel 410, effectively resisting the suction effect of the negative pressure in the negative pressure chamber 100 on the essence in the liquid storage chamber 300. This ensures that the essence only flows out when the air blowing module 500 actively pushes it out, completely eliminating the risk of passively extracting the essence due to negative pressure suction during unexpected periods, such as the pure adsorption care stage. This further ensures the precise control of the essence dosage and ensures that the essence is not sucked into the negative pressure channel. In this embodiment, through the coordinated design of the first and second states of the air blowing module 500, it complements the negative pressure mechanism 400, achieving improved accuracy, simplified structure, and optimized control while ensuring functional integration.
[0052] See further Figures 4-5The air blowing module 500 includes an annular seat 530, an elastic pipe 540 disposed around the annular seat 530, and a drive assembly 550; one end of the elastic pipe 540 is connected to the atmosphere, and the other end is connected to the liquid storage chamber 300 through the air blowing channel 520; the drive assembly 550 includes a motor 551 and a rotating head 552 connected to the output shaft 5511 of the motor; the rotating head 552 is disposed at the center of the annular seat 530, and the outer peripheral surface of the rotating head 552 is provided with a protrusion 553 for pressing the elastic pipe 540. The motor 551 has a motor output shaft 5511 at its top. An annular seat 530 is fitted onto the upper side of the motor 551. The bottom of the rotating head 552 has a circular cover plate 5521, which covers the upper side of the annular seat 530. The middle part of the rotating head 552 is inserted into the motor output shaft 5511. Driven by the motor output shaft 5511, the rotating head 552 rotates. Both sides of the rotating head 552 have cylindrical protrusions 553, which are rotatable. The protrusions 553 press against the inner circumference of the elastic tube 540. The two ends 820 of the elastic tube 540 are respectively connected to connecting nozzles 560. One end is connected to the atmosphere, and the other end is connected to the air blowing channel 520 through the connecting nozzle 560. The annular seat 530 has a groove for engaging the connecting nozzle 560. This ensures a stable connection between the pipe and the air blowing channel 520. Under the electric drive of the motor output shaft 5511, when the rotating head 552 rotates, it drives the protrusion 553 to rotate as well, pressing the gas in the elastic pipe 540. The protrusion 553 itself is rotatable, so it is not easy to get stuck during compression, which would cause poor air flow. When the protrusion 553 does not rotate, the protrusion 553 statically presses the elastic pipe 540, and the elastic pipe 540 is sealed after being pressed, so that the liquid storage chamber 300 is maintained in a negative pressure state, realizing the second state. When the protrusion 553 rotates, it is driven by the motor 551 to rotate, periodically compressing the elastic pipe 540, thereby generating pulsed positive air pressure and entering the liquid storage chamber 300, so that the essence can be intermittently delivered to the beauty head 200 to act on the skin, with uniform and controllable liquid output.
[0053] Furthermore, at least two protrusions 553 are provided at circumferential intervals along the rotating head 552. The rotating head 552 is configured such that when it rotates under the drive of the motor 551, the protrusions 553 alternately squeeze the elastic channel 540 to generate intermittent positive air pressure through the elastic recovery of the elastic channel 540. In this embodiment, the rotating head 552 has cylindrical protrusions 553 on both sides. The upper end of the protrusion 553 is rotatably inserted into the upper end of the rotating head 552, and the lower end is rotatably inserted into the circular cover plate 5521. When the motor 551 shaft drives the rotating head 552 to rotate, the protrusion 553 rotates accordingly, and the entire protrusion 553 can rotate on its own, so that it runs smoothly when squeezing the elastic channel 540. The protrusions 553 with circumferential gaps alternately squeeze the elastic channel 540 surrounding the outer circumference of the rotating head 552, so that the rotating head 552 can squeeze the elastic channel 540 multiple times per rotation, which increases the frequency of positive pressure output, making the essence delivery more continuous and stable. It can effectively avoid the problem of excessively long pulse intervals and discontinuous liquid flow that may be caused by single-point squeezing. At the same time, by controlling the rotation frequency of the rotating head 552, the interval time of liquid output can be controlled to ensure that the rhythm of essence being introduced into the skin by the microneedle chip 210 is controllable.

Figures 6 to 8The device also includes a connector platform 600 located on the main body 10 of the beauty device; the liquid storage cavity 300 is a bottle body 310 structure, and the cap end of the bottle body 310 is provided with a connector portion 311 adapted to the connector platform 600; the connector platform 600 is provided with a conical protrusion 610, and the outer peripheral surface of the conical protrusion 610 has two spaced cuts 611. One side of the beauty device main body 10 is provided with a connector platform 600 for inserting a bottle body 310 with a liquid storage cavity 300. The bottle mouth of the bottle body 310 usually has a sealing membrane to seal the liquid storage cavity 300. The conical protrusion 610 in the middle of the connector platform 600 can quickly puncture the sealing membrane, and the liquid storage cavity 300 is connected to the air blowing module 500 through the two cuts 611 provided on the conical protrusion 610. The cuts 611 correspond to the air blowing channel 520 and the fluid channel 510, respectively; wherein, one of the conical protrusions 610... The bottom of the cut 611 is provided with a first hole 612, which communicates with the blowing module 500 through the blowing air passage 520; when the insertion part 311 of the bottle body 310 is inserted into the conical protrusion 610, the first hole 612 communicates with the interior of the bottle body 310; the other end of the cut 611 of the conical protrusion 610 is provided with a second hole 613, which communicates with the liquid outlet port 220 through the fluid pipe 510; when the insertion part 311 of the bottle body 310 is inserted into the conical protrusion 610, the first hole 612 communicates with the interior of the bottle body 310; when the insertion part 311 of the bottle body 310 is inserted into the conical protrusion 610, the first hole 612 communicates with the interior of the bottle body 310 through the blowing air passage 520. When the conical protrusion 610 is inserted, the second hole 613 communicates with the interior of the bottle body 310. The bottom of the conical protrusion 610 is cylindrical, and the two cuts 611 formed by the conical part are the openings of the first hole 612 and the second hole 613. The first hole 612 and the second hole 613 are opened inside the cylindrical part. When the insertion part 311 is inserted into the conical protrusion 610, the conical surface of the conical protrusion 610 punctures the insertion part 311 and it is locked at the bottom of the cylindrical part, forming a fit with the bottle cap insertion part 311. The reliable seal, through its conical surface, can adapt to the slight dimensional error of the insertion part 311 of the bottle body 310. When inserted, it automatically aligns with the cut 611 to achieve quick insertion, making the operation extremely simple. It effectively avoids misalignment and leakage of gas and liquid pipelines during insertion. At the same time, its design with the conical surface at the top and the channel hole at the bottom column also makes it less likely to be deformed by the force during the puncture process during repeated use. This prevents the first hole 612 and the second hole 613, which serve as the air inlet and liquid outlet channels, from being deformed and affecting the smoothness, thus ensuring smooth liquid discharge.
[0055] See Figure 9The negative pressure suction channel 410 is provided with a three-way pipe 420; the first port 421 of the three-way pipe 420 is connected to the negative pressure mechanism 400, the second port 422 is connected to the negative pressure suction port 110, and the third port 423 is connected to an electronic valve 700; when the negative pressure mechanism 400 stops pumping air, the electronic valve 700 opens to connect the negative pressure suction channel 410 to the atmosphere, so that the negative pressure in the negative pressure cavity 100 disappears. The negative pressure mechanism 400 is installed inside the body 10 of the beauty device. Its top air inlet pipe is connected to the first port 421 of the three-way pipe 420 via a pipe. The second port 422 is connected to the negative pressure suction port 110 via a pipe. The third port 423 is connected to the electronic valve 700 via a pipe. When the negative pressure mechanism 400 is working, it creates a negative pressure state within the negative pressure chamber 100 by suction, allowing it to adhere to the skin for beauty treatments. When it is necessary to release the adhesion, the electronic valve 700 is activated, and the negative pressure suction channel 410 opens through the three-way pipe... The 420 unit instantly connects to the atmosphere, allowing the negative pressure within the negative pressure chamber 100 to be immediately eliminated. This design facilitates operation and prevents skin redness caused by residual negative pressure when the user removes the device, effectively improving operational safety and user experience. Furthermore, it eliminates the need for frequent starting, stopping, or reversing of the negative pressure mechanism 400 to release pressure, reducing wear and helping to extend the lifespan of core components. In addition, the opening and closing of the electronic valve 700 can be precisely controlled by a program, enabling accurate linkage with other functions and enhancing the overall system's intelligent control level.
[0056] Furthermore, it also includes an integrated module 800; the integrated module 800 internally provides the insertion platform 600, the liquid storage bottle replacement port 810, the air blowing channel 520, the fluid pipeline 510, and the negative pressure suction channel 410; the liquid storage bottle replacement port 810 is positioned corresponding to the insertion platform 600, and is used for inserting or removing the bottle body 310 of the liquid storage chamber 300; the integrated module 800 has an opening 820 on the side facing the negative pressure chamber 100, and a connector 830 is provided in the opening 820; one end of the connector 830 is connected to the beauty head 200, and the other end is connected to the fluid pipeline 510 and the negative pressure suction channel 410 of the integrated module 800 respectively. The integrated module 800 has a housing 840, which integrates the air blowing channel 520, the fluid pipe 510, and the negative pressure suction channel 410 into the inner cavity of the housing 840. The bottom of the housing 840 has two interfaces 841. One end of one interface is connected to a pipe connected to the negative pressure mechanism 400, and the other end of the interface 841 is connected to the negative pressure suction pipe, so that the other end of the negative pressure suction pipe is connected to the negative pressure suction port 110. The other interface 841 is connected to the pipe of the suction module. Inside, the negative pressure suction channel 410 and the air blowing channel are integrated into the inner cavity of the housing 840, which is connected to the air blowing channel 520. A liquid storage bottle replacement port 810 is formed in the middle of the housing 840, and an insertion platform 600 is formed in the middle of the liquid storage bottle replacement port 810. Connection ports 850 and 841 are formed in the inner cavity of the housing 840 corresponding to the first hole 612 and the second hole 613, respectively. The air blowing channel 520 and the fluid pipeline 510 are both inserted into the connection ports 850 and 841 to ensure the stable connection of the pipeline. The top of the housing 840 is an opening 820, into which a connector 830 is inserted. The top of the connector 830 protrudes and is fixed with a beauty head 200. The middle part has a connecting hole that connects to the liquid outlet port 220, and the bottom connects to the fluid pipe 510 to form a liquid outlet channel. The negative pressure suction port 110 is opened on the connector 830 and connects to the negative pressure suction channel 410, thus integrating multiple pipes for liquid inlet, negative pressure and air blowing. This allows all internal pipes and interfaces 841 to be pre-integrated into one module, avoiding the step of connecting multiple small pipes one by one in the complex assembly of the whole machine, reducing the potential risk of air leakage and liquid leakage, improving the reliability and sealing of the product, and simplifying the assembly process of the whole machine. Furthermore, the integrated module 800 is an independent unit, which facilitates subsequent overall replacement or maintenance.
[0057] See Figures 10 to 12Furthermore, it also includes a vibration module 900; the vibration module 900 includes a drive motor 910, an eccentric drive connector 920, and a connecting shell 930; the connecting shell 930 is sleeved on the eccentric rotating member and is drively connected to the connecting shell 930; the integrated module 800 is sleeved in the cavity of the connecting shell 930, and the connecting shell 930 can be vibratedly installed inside the beauty device body 10; the drive motor 910 drives the eccentric drive connector 920 to rotate eccentrically, so that the connecting shell 930 is axially limited and can vibrate relative to the beauty device body 10; a buffer ring 430 is provided inside the opening 820 to surround the outer periphery of the connector 830; the edge of the opening 820 of the connecting shell 930 is folded to form a limiting edge 931, and when the connecting shell 930 vibrates, there is a gap between the outer periphery of the limiting edge 931 and the inner wall of the beauty device body 10.The drive motor 910 is fixed to the inner cavity of the beauty device body 10. The eccentric rotating connector 830 is inserted into the output shaft of the drive motor 910. The bottom of the connecting shell 930 has an annular sleeve portion 932 that fits around the outer periphery of the eccentric drive connector 920. The connecting shell 930 is fitted around the outer periphery of the housing 840 of the integrated module 800. The housing 840 has a groove around its bottom, and the two sides of the connecting shell 930 have corresponding elastic buckles 933. The ends of the elastic buckles 933 are engaged in the grooves, so that the connecting shell 930 can stably drive the integrated module 800 to vibrate when it vibrates. Furthermore, when the drive motor 910 drives the eccentric drive connector 920 to rotate eccentrically, it causes the connecting shell 930 and the integrated module 800 to vibrate up and down. This makes it easier for the microneedle chip 210 to penetrate the stratum corneum during vibration, promoting the penetration of the essence into the dermis and further promoting the penetration and diffusion of the essence into the deeper layers of the skin, thereby enhancing the skincare effect. A buffer ring 430 made of elastic material is fitted around the outer periphery of the connector 830. The buffer ring 430 has a multi-layered compressed elastic arc ring. When the connecting shell 930 vibrates, causing the beauty head 200 to vibrate, the buffer ring 430 can... The shock force transmitted by the vibration absorption module 900 is absorbed, making the vibration more gentle and providing a more comfortable user experience. The top of the buffer ring 430 is connected to a negative pressure sleeve 440 surrounding the beauty head 200. The buffer ring 430 and the negative pressure sleeve 440 form a negative pressure cavity 100, thus creating a negative pressure state at the beauty head 200. The limiting edge 931 formed by the folding of the edge of the connecting shell 930 has a certain gap with the inner wall of the beauty device body 10, and this gap is greater than the gap generated when the connecting shell 930 vibrates, thus keeping the connecting shell 930 in a suspended state and preventing vibration from being transmitted to the entire body. The outer shell of the beauty device causes hand discomfort, and the buffer ring 430 further prevents vibration energy from being transmitted outward through the connector 830, ensuring effective utilization of vibration and stability of the overall structure. In addition, a step 120 is provided on the inner wall of the beauty device near the limiting edge 931, and the opening 820 of the step 120 is smaller than the limiting edge 931. With the cooperation of the limiting edge 931, it is ensured that the connecting shell 930 can be in a suspended state and has a blocking effect, making it difficult for objects to enter the inner cavity of the beauty device through the gap between the connecting shell 930 and the inner wall of the beauty device, thus affecting the normal operation of the internal components.
[0058] Example 2
[0059] This embodiment also provides a control method for a beauty device, applied to the aforementioned beauty device, comprising the following steps:
[0060] S1. The negative pressure mechanism 400 is activated to evacuate the negative pressure suction channel 410, so that the negative pressure cavity 100 forms a negative pressure area that adsorbs the skin; at this time, the air blowing module 500 is in the second state to maintain the negative pressure state of the liquid storage cavity 300.
[0061] S2. When at least one of the following conditions is met, control the air blowing module 500 to switch from the second state to the first state: (a) the negative pressure area formation time in the negative pressure cavity 100 reaches a preset time t1; (b) the negative pressure value in the negative pressure suction channel 410 is detected to reach a preset negative pressure value P1; (c) a user-triggered liquid blowing command is received.
[0062] S3. When the air blowing module 500 is in the first state, control the air blowing module 500 to generate intermittent positive air pressure, and transport the essence in the liquid storage chamber 300 to the liquid outlet port 220 through the fluid pipe 510.
[0063] S4. When the liquid blowing is completed, control the air blowing module 500 to switch from the first state back to the second state, and control the electronic valve 700 to open, so that the negative pressure suction channel 410 is connected to the atmosphere, and the negative pressure area in the negative pressure cavity 100 is released.
[0064] In this embodiment, the above-described control method enables the sequential and coordinated operation of the two core functions: negative pressure adsorption and essence delivery. Ensuring firm adsorption before delivery, steps S1 and S2 specify that essence delivery is only initiated after a stable negative pressure zone has formed. This ensures that the microneedle chip 210 operates under the premise of stable adsorption on the skin, guaranteeing the effectiveness and safety of the operation. Simultaneously, the second state of the air blowing module 500 effectively isolates the negative pressure mechanism 400 from interference with the liquid storage chamber 300 during the pure adsorption phase, ensuring precise subsequent liquid blowing. Furthermore, by first controlling the air blowing module 500 to switch back to the second state and then opening the electronic valve 700 to release the negative pressure in the negative pressure chamber 100, the backflow of essence during the moment of negative pressure release is avoided.
[0065] Furthermore, step S3 also includes activating the vibration module 900 to drive the beauty head 200 to vibrate. Synchronizing the vibration function with the essence delivery achieves a synergistic effect of absorption and penetration promotion. The vibration module 900 begins vibrating simultaneously with the essence flow, effectively promoting its penetration and diffusion, avoiding uneven absorption or waste that might occur if the essence is dispensed before or after vibration, thus maximizing treatment efficiency and effectiveness.
[0066] Furthermore, in steps S1 and S4, the second state of the air blowing module 500 is achieved by controlling the rotating head 552 of the drive assembly 550 to stop rotating, and the protrusion 553 of the rotating head 552 compresses the elastic pipe 540 to seal the elastic pipe 540, thereby maintaining the negative pressure state of the liquid storage chamber 300. By controlling the motor 551 to stop rotating and using the protrusion 553 to remain in the compression position to continuously seal the elastic pipe 540, the air passage is physically locked, maintaining the negative pressure state of the liquid storage chamber 300; no additional energy consumption is required, the structure is simple to implement, and the reliability is high.
[0067] Furthermore, in steps S1 and S4, the second state of the air-blowing module 500 is achieved by controlling the rotating head 552 of the drive component 550 to rotate in the opposite direction, and alternately squeezing the elastic pipe 540 through the protrusion 553, so that the elastic pipe 540 generates a suction force opposite to the air-blowing direction to maintain the negative pressure state of the liquid storage chamber 300. This method provides a dynamic and adjustable second state implementation scheme. By controlling the motor 551 to rotate in the opposite direction, the air-blowing module 500 actively draws air from the liquid storage chamber 300 to maintain its negative pressure, thereby enabling more precise control of the negative pressure level in the liquid storage chamber 300, and providing a stronger and more stable effect against external negative pressure suction, making it suitable for scenarios with higher pressure control requirements.
[0068] Furthermore, in step S3, the start-up time of the vibration module 900 is synchronized with the time when the air blowing module 500 switches to the first state, or delayed by 1-500ms. Starting vibration simultaneously with the outflow of the essence immediately promotes its penetration and diffusion, avoiding uneven absorption or waste that might occur if the essence is expelled before or after vibration, maximizing the efficiency and effectiveness of the treatment. Setting a short delay in start-up time allows a small amount of essence to pre-wet the microneedle chip 210 and the skin surface before vibration is activated for infusion. This slight timing difference avoids essence splashing that might occur during the initial vibration, ensuring the liquid is more smoothly and concentratedly introduced into the skin, further improving dosage accuracy and user experience.
[0069] Furthermore, in step S4, the conditions for determining the completion of the blow-drying process include: the blow-drying module 500 being in the first state for a preset blow-drying time t2, or the blow-drying module 500 generating intermittent positive pressure a preset number of times n. This provides two quantitative and reliable criteria for determining the termination of the blow-drying process. By controlling the output through time t2 or the number of times n, the total output of the essence can be precisely managed and repeated, ensuring consistency in the dosage for each treatment. Users can select different settings as needed to achieve personalized care, avoiding waste or skin burden caused by overuse, and also preventing insufficient dosage from affecting the effect.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention.
