Description

Technical Field

[0001] The present invention relates to the technical field of beauty instruments, and in particular to a handheld ultrasonic beauty instrument. Background Art

[0002] An ultrasonic beauty device is an instrument that uses ultrasonic technology (high-frequency mechanical vibration waves) to act on human skin and deep tissues to achieve beauty care and improve skin condition. Its core principle is to use the physical effects of ultrasound (such as mechanical vibration, thermal effect, cavitation, etc.) to act on the surface and dermis of the skin to promote skin metabolism, enhance nutrient absorption, and improve skin quality, thereby achieving a beauty effect.

[0003] Since air is a poor conductor of ultrasound, if the instrument probe comes into direct contact with dry skin, most of the energy will be lost in the air gap between the probe and the skin and cannot be effectively transmitted to deep tissues, significantly reducing the beauty effect. Therefore, ultrasonic beauty devices must be used with media such as beauty serums, gels or essences.

[0004] Since people with different skin types have different adaptability to beauty serum concentration, existing ultrasonic beauty devices only have basic beauty serum storage and quantitative output functions. Therefore, before using the beauty device each time, the operator needs to manually mix the beauty serum according to the customer's skin type. This operation process is not only tedious and time-consuming, but also manual mixing is difficult to accurately meet the user's skin needs, resulting in a deviation between the beauty serum concentration and the actual needs of the skin, ultimately affecting the accuracy and effectiveness of the beauty effect. In addition, the existing device directly outputs the thin water-like beauty serum, which is not only easy to lose and waste, but also difficult to penetrate the gaps in the skin's stratum corneum, resulting in low absorption efficiency of active ingredients. Summary of the Invention

[0005] The purpose of the present invention is to propose a handheld ultrasonic beauty instrument to solve the problem that existing ultrasonic beauty instruments cannot adjust the concentration of beauty liquid according to the user's skin type, resulting in a cumbersome beauty process and difficulty in fully exerting the effectiveness of ultrasonic beauty.

[0006] To achieve the above objectives, the present invention adopts the following technology: a handheld ultrasonic beauty instrument comprising a handle, a connecting shell fixed at one end of the handle, a probe fixed at the open end of the connecting shell, an ultrasonic generator a fixedly installed inside the probe, and further comprising:

[0007] An atomization mechanism comprising a storage cartridge fixed to the interior of a handle, a partition fixed to the interior of the storage cartridge, a micropump fixedly installed in the interior of the handle, a proportional valve provided between the micropump and the storage cartridge, an ultrasonic generator b fixedly installed in the interior of the probe, a flow guide unit provided in the interior of the connecting shell, and an adjustment assembly and a flow direction control unit provided between the flow guide unit and the connecting shell;

[0008] The air guide unit includes an air guide cover, and a baffle is fixed on the edge of the air guide cover;

[0009] When the deflector is suspended, the beauty liquid is diverted, and the ultrasonic generator b accelerates the atomization of the beauty liquid; when the deflector and the ultrasonic generator b are in contact with each other, the ultrasonic generator b cavitates and mixes the beauty liquid.

[0010] As a further description of the above technical solution: the top surface of the ultrasonic generator b is concave, and the distance from the ultrasonic focusing point to the surface of the ultrasonic generator b is the same as the height of the air guide cover.

[0011] As a further description of the above technical solution: the adjustment component includes a fixed cylinder fixed inside the connecting shell and connected to the liquid outlet of the micro pump, the interior of the fixed cylinder is movably connected to the external connecting pipe, and the interior of the fixed cylinder is fixedly installed with an electric telescopic rod.

[0012] As a further description of the above technical solution: the flow direction control unit includes an inner connecting tube movably connected to the inner part of the outer connecting tube, a support plate is fixed to the telescopic end of the electric telescopic rod, and a spring is provided on the top of the outer connecting tube.

[0013] As a further description of the above technical solution: an impeller is fixedly connected to the inner wall of the inner connecting pipe.

[0014] As a further description of the above technical solution: a through hole is opened at the bottom of the air deflector, and the support plate seals the through hole at the bottom of the air deflector.

[0015] As a further description of the above technical solution: it also includes an additional structure, which includes a storage box threadedly connected to the outside of the handle, an annular shell slidably connected to the inside of the storage box, an elastic cover is installed at the bottom of the annular shell, and a control component is provided on the top of the annular shell.

[0016] As a further description of the above technical solution: the control assembly includes a connecting rod fixed to the top of the annular shell, and the top of the storage box is rotatably connected to a nut threadedly connected to the connecting rod.

[0017] As a further description of the above technical solution: the probe is connected to the annular shell, and the bottom of the storage box is in contact with the outside of the probe.

[0018] In summary, due to the use of the above-mentioned technology in a handheld ultrasonic beauty instrument, the beneficial effects of the present invention are:

[0019] First, the proportioning system constructed by the micro pump and the proportional valve in this application can dynamically adjust the concentration of the beauty liquid in real time during the operation of the ultrasonic beauty instrument. Based on the user's immediate skin quality needs (such as the low stimulation needs of dry and sensitive skin, the oil control intensity of oily skin) and scene changes (skin water and oil imbalance caused by seasonal changes, barrier protection needs during the post-medical beauty repair period, seasonal changes, and post-medical beauty repair), the mixing ratio of the concentrated beauty liquid and the solvent is accurately controlled, so that highly active ingredients (such as anti-aging peptides and antioxidants) act on the skin at the most suitable concentration, avoiding the blind spots of traditional fixed-concentration products. On this basis, the ultrasonic generator b can also convert the proportioned beauty liquid into nano-scale droplets, significantly improving the transdermal absorption rate, thereby enhancing the beauty effect.

[0020] Secondly, the present application not only diverts the beauty liquid through the diversion unit, thereby promoting the atomization of the beauty liquid by the ultrasonic generator b, but also prevents the effective contact area between the beauty liquid and the ultrasonic generator b from being reduced during the handheld movement of the ultrasonic beauty device, thereby ensuring that the ultrasonic generator b can continuously and evenly atomize the beauty liquid to act on the human body, thereby improving the use effect of the beauty device;

[0021] Moreover, through the cooperation among the flow guide unit, the regulating component and the flow direction control unit, the ultrasonic generator b can utilize the ultrasonic cavitation effect to chemically reconstruct the beauty serum containing oily ingredients, macromolecular ingredients and encapsulated ingredients. After that, the beauty serum can be directly penetrated after being atomized and contacts the skin, without the need for secondary emulsification or diffusion, thereby giving full play to the effect of the beauty serum.

[0022] Third, the present application not only can apply viscous beauty liquid (such as gel, paste, high-concentration essence, etc.) during the use of the beauty instrument through the additional structure, but also can make use of the atomization and vibration functions of the atomization mechanism to make the viscous beauty liquid fully mixed with the atomized solvent when flowing out, thereby achieving the regulation of the viscosity of the beauty liquid and improving the uniformity, penetration efficiency and beauty effect of the beauty liquid.

[0036] The following will be combined with the accompanying drawings to clearly and completely describe the technology of the present invention, a handheld ultrasonic beauty device, in accordance with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1-9 As shown, the present invention provides a handheld ultrasonic beauty instrument: including a handle 10, a connecting shell 11 is fixed at one end of the handle 10, a stainless steel probe 12 is fixed at the open end of the connecting shell 11, and an ultrasonic generator a13 is fixedly installed inside the probe 12. After the ultrasonic generator a13 is started, the vibration is transmitted to the human body through the probe 12. Under the action of the vibration, the human body accelerates the absorption of the beauty liquid, thereby achieving a beauty effect.

[0038] Reference Figure 2 and Figure 3 In order to adjust the concentration of the beauty liquid in real time according to the scene changes and the user's skin type, an atomization mechanism 20 is also included. The atomization mechanism 20 includes a storage cylinder 21 fixed to the inside of the handle 10. A feeding tube that passes through the handle 10 is fixed to the top of the storage cylinder 21. A cavity for installing a circuit board is reserved between the storage cylinder 21 and the handle 10. A partition 22 is fixed inside the storage cylinder 21 to divide the internal space into two parts. The two parts of the storage cylinder 21 are used to store concentrated beauty liquid and solvent respectively. A micro pump 23 is fixed inside the handle 10. The liquid inlet of the micro pump 23 is connected to the two parts of the internal space of the storage cylinder 21 through a three-way pipe. A proportional valve 24 installed on the three-way pipe is provided between the micro pump 23 and the storage cylinder 21 for adjusting the ratio of the concentrated beauty liquid and the solvent to achieve the adjustment of the concentration of the beauty liquid. An ultrasonic generator b25 is fixed inside the probe 12. After the ultrasonic generator b25 is started, it atomizes the beauty liquid flowing onto its surface through high-frequency vibration.

[0039] Reference Figure 4 and Figure 5 A flow guide unit 26 is provided inside the connecting shell 11. The flow guide unit 26 includes a flow guide cover 261. The flow guide cover 261 is conical and has a plurality of flow channels arranged equidistantly around its center point. Through the multiple flow channels, the beauty liquid can be evenly dispersed into multiple streams and then contact the ultrasonic generator b25. As a result, the beauty liquid can be fully dispersed when contacting the ultrasonic generator b25, expanding the contact area with the ultrasonic generator b25, thereby accelerating the vibration atomization of the beauty liquid.

[0040] The top surface of the ultrasonic generator b25 is concave. When the deflector 261 is suspended above the ultrasonic generator b25, the beauty liquid sprayed from the flow channel of the deflector 261 will drip onto the edge of the surface of the ultrasonic generator b25, and then slide towards the concave center of the ultrasonic generator b25. During this process, the liquid droplets will further expand the contact area with the surface of the ultrasonic generator b25 due to rolling, thereby further accelerating the rate of vibration atomization.

[0041] Reference Figure 4 、 Figure 5 and Figure 6An adjustment component 27 and a flow direction control unit 28 are provided between the flow guide unit 26 and the connecting shell 11. The adjustment component 27 includes a fixed cylinder 271 fixed to the inside of the connecting shell 11 and connected to the liquid outlet of the micro pump 23. The interior of the fixed cylinder 271 is movably connected to an external connecting pipe 272. An electric telescopic rod 274 is fixedly installed inside the fixed cylinder 271. By controlling the extension and retraction of the electric telescopic rod 274, the height of the flow guide cover 261 can be adjusted, thereby adjusting the position where the beauty liquid sprayed from the flow channel of the flow guide cover 261 drips onto the ultrasonic generator b25. When the output volume of the beauty liquid is low, the flow guide cover 261 is lowered to make the sprayed beauty liquid closer to the center position of the ultrasonic generator b25. Since the amount of beauty liquid sprayed is reduced and the vibration of the ultrasonic generator b25 is stronger when it is closer to the center position, the beauty liquid can be vibrated and atomized faster, thereby ensuring the output speed of the beauty liquid.

[0042] The flow direction control unit 28 includes an internal connecting tube 281 movably connected to the inside of the external connecting tube 272. A support plate 282 is fixed to the telescopic end of the electric telescopic rod 274. A spring 273 is provided on the top of the external connecting tube 272. The extension and retraction of the electric telescopic rod 274 directly drives the support plate 282 to move in the vertical direction. The spring 273 is always in a compressed state. Therefore, when the support plate 282 moves, the air guide cover 261 can maintain contact with the support plate 282 under the elastic force of the spring 273.

[0043] Taking into account that the ultrasonic beauty instrument needs to be handheld, it is inevitable that the beauty instrument will be tilted during use. In order to maintain stable contact between the beauty liquid and the ultrasonic generator b25 and stable atomization output of the beauty liquid, a baffle 262 is fixed to the edge of the deflector 261. The electric telescopic rod 274 is controlled to extend to drive the support plate 282 to move downward. The elastic force of the spring 273 drives the external connecting tube 272 and the deflector 261 to move downward until the bottom of the deflector 261 contacts the ultrasonic generator b25. At this time, under the limiting backflow and diversion effect of the baffle 262, the beauty liquid sprayed from the flow channel of the deflector 261 can directly contact the ultrasonic generator b25, thereby achieving the effect of stable contact between the beauty liquid and the ultrasonic generator b25.

[0044] When using a beauty liquid containing oily ingredients, macromolecular ingredients or encapsulated ingredients, in order to enable the beauty instrument to fully exert the effect of the beauty liquid, a through hole is opened at the bottom of the deflector 261, and the supporting plate 282 seals the bottom through hole of the deflector 261. A sealing ring is fixed to the bottom of the deflector 261. When the deflector 261 contacts the ultrasonic generator b25 and the sealing ring is used to seal the two, the spring 273 applies a downward elastic force to the deflector 261, and the deflector 261 and the ultrasonic generator b25 remain in a sealed state. The electric telescopic rod 274 is controlled to extend to drive the supporting plate 282 and the internal connecting tube 281 to move downward, and the supporting plate 282 opens the through hole at the bottom of the deflector 261, and the internal connecting tube 281 seals the flow channel of the flow guide 261. The beauty liquid output by the micro pump 23 now flows through the fixed cylinder 271, the external connecting tube 272, and the internal connecting tube 281 into the space between the flow guide 261 and the ultrasonic generator b25 until the liquid level rises to the height of the through-hole. At this time, the ultrasonic generator b25 is activated and chemically reconstitutes the beauty liquid through the ultrasonic cavitation effect. The beauty liquid level continues to rise, enters the flow channel of the flow guide 261 through the through-hole, and then flows out and contacts the ultrasonic generator b25. It is atomized by the vibration of the ultrasonic generator b25. At this time, the output can directly penetrate the skin after contacting it, without the need for secondary emulsification or diffusion, and can fully exert the effect of the beauty liquid.

[0045] The recessed ultrasonic generator b25 focuses the ultrasonic wave. The distance from the ultrasonic focusing point to the surface of the ultrasonic generator b25 is the same as the height of the flow guide 261. After the internal connecting tube 281 descends close to the surface of the ultrasonic generator b25, the beauty liquid input between the flow guide 261 and the ultrasonic generator b25 by the micro pump 23 through the internal connecting tube 281 will flow from bottom to top, from the bottom of the flow guide 261 with a large diameter to the top of the flow guide 261 with a small diameter. The recessed ultrasonic generator b25 focuses the ultrasonic wave on the small diameter of the top of the flow guide 261, fully utilizing the ultrasonic cavitation effect to vibrate, crush and mix the beauty liquid about to flow out through the through hole and flow channel, thereby improving the use effect of the beauty liquid.

[0046] In order to further improve the atomization rate of the beauty liquid after the diversion of the deflector 261 and the effect of chemically reconstructing the beauty liquid by using the ultrasonic cavitation effect, the inner wall of the internal connecting pipe 281 is fixedly connected with an impeller 29. When the support plate 282 contacts the deflector 261, the deflector 261 is suspended in the air. When the beauty liquid delivered by the micro pump 23 passes through the internal connecting pipe 281, it pushes the impeller 29 to drive the internal connecting pipe 281 and the support plate 282 to rotate. The support plate 282 drives the deflector 261 and the external connecting pipe 272 to deflect through the friction force, further making the beauty liquid from the flow channel of the deflector 261 The outflowing beauty liquid can be dispersed and dripped onto the ultrasonic generator b25, thereby improving the atomization efficiency. When the support plate 282 is not in contact with the deflector 261, the deflector 261 is in contact and sealed with the ultrasonic generator b25. The beauty liquid delivered by the micro pump 23 passes through the internal connecting tube 281, pushing the impeller 29 to drive the internal connecting tube 281 and the support plate 282 to rotate. A spoiler is fixed to the bottom of the support plate 282. The spoiler stirs the beauty liquid between the deflector 261 and the ultrasonic generator b25, assisting the cavitation effect and further improving the use effect of the beauty liquid.

[0047] Reference Figure 8 and Figure 9 When the deflector 261 is suspended in the air, the beauty liquid will be diverted, and the diverted beauty liquid will be sprayed to the position near the edge of the top surface of the ultrasonic generator b25. Then, it will be accelerated into atomization under the ultrasonic vibration during the process of flowing toward the middle of the surface of the ultrasonic generator b25; when the deflector 261 and the ultrasonic generator b25 are in contact with each other, the space between the deflector 261 and the ultrasonic generator b25 is filled with beauty liquid. At this time, a large amount of beauty liquid gathers between the deflector 261 and the ultrasonic generator b25, and the ultrasonic generator b25 cavitates and mixes the beauty liquid.

[0048] Reference Figure 3 The top of the annular shell 32 is provided with a control component 34, and the probe 12 is connected to the annular shell 32. When the bottom of the annular shell 32 contacts the bottom of the inner wall of the storage box 31, the beauty liquid in the storage box 31 is blocked by the annular shell 32 and will not flow out through the discharge port at the bottom of the storage box 31. When the bottom of the annular shell 32 does not contact the bottom of the inner wall of the storage box 31, the atomized solvent in the probe 12 will enter the annular shell 32 and contact the flowing beauty liquid to adjust the viscosity of the beauty liquid. The bottom of the storage box 31 contacts the outside of the probe 12, and the vibration of the probe 12 can promote the mixing of the atomized solvent and the viscous beauty liquid.

[0049] Reference Figure 7 The control assembly 34 includes a connecting rod 341 fixed to the top of the annular shell 32. The top of the storage box 31 is rotatably connected to a nut 342 threadedly connected to the connecting rod 341. Twisting the two nuts 342 drives the connecting rod 341 to move upward or downward through the threads, thereby driving the annular shell 32 to rise or fall, controlling the outflow of the beauty liquid inside the storage box 31.

[0050] Working principle: When using an ultrasonic beauty instrument in combination with a water-like thin beauty liquid for beauty treatment, the concentrated beauty liquid and the diluent are poured into the two spaces of the storage cylinder 21 separated by the partition 22 through the feed pipe. The proportional valve 24 is controlled to adjust the ratio of the concentrated beauty liquid and the diluent according to the user's skin condition and actual needs, so that the beauty liquid is diluted to an appropriate concentration range. After the user lies down, the micro pump 23, ultrasonic generator b25 and ultrasonic generator a13 are activated, and the probe 12 is placed on the user's desired beauty area. The vibration generated by the activation of the ultrasonic generator a13 is transmitted to the skin through the probe 12. The micropump 23 delivers the beauty liquid to the probe 12 through the flow channel of the fixed cylinder 271, the external connecting tube 272, the internal connecting tube 281, and the flow guide cover 261. The beauty liquid sprayed from the flow channel drips onto the edge of the surface of the ultrasonic generator b25 and flows toward the recessed center of the ultrasonic generator b25. During this process, the ultrasonic generator b25 atomizes the beauty liquid through ultrasonic vibration. The atomized beauty liquid is sprayed through the annular shell 32 and the discharge port at the bottom of the storage box 31 to the space between the elastic cover 33 and the probe 12, where it contacts the user's skin. The probe 12 uses ultrasonic waves to ensure that the beauty liquid is fully absorbed by the skin, achieving a beauty effect.

[0051] When the beauty liquid passes through the inner connecting tube 281, it pushes the impeller 29, driving the inner connecting tube 281, the support plate 282 and the flow guide 261 to rotate. The beauty liquid flowing out of the flow channel of the flow guide 261 is evenly sprayed onto the surface of the ultrasonic generator b25, further improving the vibration atomization effect of the beauty liquid.

[0052] When using a beauty serum containing oily ingredients, macromolecular ingredients or encapsulated ingredients, before the ultrasonic generator b25 is activated, the electric telescopic rod 274 is controlled to extend to drive the support plate 282 and the inner connecting tube 281 to move downward. The elastic force of the spring 273 drives the outer connecting tube 272 and the flow guide cover 261 to move downward synchronously with the support plate 282. After the flow guide cover 261 contacts and seals with the ultrasonic generator b25, the electric telescopic rod 274 is controlled to extend to drive the support plate 282 and the inner connecting tube 281 to continue to move downward, so that the support plate 282 opens the bottom through hole of the flow guide cover 261, and the inner connecting tube 281 closes the flow channel of the flow guide cover 261. At this time, the micro pump 23 outputs The beauty liquid flows through the fixed cylinder 271, the external connecting tube 272, and the internal connecting tube 281 into the space between the flow guide 261 and the ultrasonic generator b25. When the liquid level reaches the level of the through hole, the ultrasonic generator b25 is activated to vibrate, crush, and mix the beauty liquid through ultrasonic cavitation. The micropump 23 then continues to pump the beauty liquid between the flow guide 261 and the ultrasonic generator b25. As the liquid level continues to rise, it enters the flow channel of the flow guide 261 through the through hole, flows out, and contacts the ultrasonic generator b25. The vibration of the ultrasonic generator b25 atomizes the atomized beauty liquid, which penetrates directly into the skin, fully exerting its effects.

[0053] During this process, the beauty liquid flowing through the inner connecting pipe 281 is also driven by the impeller 29 to rotate the inner connecting pipe 281 and the supporting plate 282. Since the supporting plate 282 does not contact the deflector 261, the deflector 261 does not rotate at this time. The supporting plate 282 rotates to stir the beauty liquid through the bottom spoiler, further improving the mixing effect of the beauty liquid.

[0054] When the beauty instrument is used with viscous beauty liquid, the beauty liquid is poured into the storage box 31 and the solvent is poured into the storage tube 21. At this time, the bottom of the annular shell 32 contacts the bottom of the inner wall of the storage box 31. The beauty liquid inside the storage box 31 is blocked by the annular shell 32 and will not flow out through the discharge port at the bottom of the storage box 31. When the beauty instrument is used, the two nuts 342 are screwed to drive the connecting rod 341 to move upward through the thread, driving the annular shell 32 to rise and open the discharge port at the bottom of the storage box 31. The beauty liquid inside the storage box 31 flows out under gravity. At this time, the atomized solvent inside the probe 12 will enter the annular shell 32 and contact with the flowing beauty liquid to adjust the viscosity of the beauty liquid. At the same time, the ultrasonic generator b25 transmits vibration through the probe 12 to promote the mixing of the atomized solvent and the viscous beauty liquid.
