Description

Technical Field

[0001] This invention relates to the field of beauty equipment technology, and in particular to a handheld ultrasonic beauty device. Background Technology

[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 and skin care and improve skin condition. Its core principle is to use the physical effects of ultrasonic waves (such as mechanical vibration, thermal effect, cavitation effect, etc.) to act on the skin surface and dermis to promote skin metabolism, enhance nutrient absorption, and improve skin texture, thereby achieving beauty effects.

[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 the deep tissues, resulting in a significant reduction in the cosmetic effect. Therefore, ultrasonic beauty devices must be used in conjunction with beauty serums, gels, or essences.

[0004] Because different skin types have varying tolerances to different concentrations of beauty serum, existing ultrasonic beauty devices only have basic functions for storing and dispensing beauty serum. Therefore, operators must manually mix the beauty serum according to the client's skin type before each use. This process is not only tedious and time-consuming, but manual mixing also makes it difficult to accurately match the user's skin type needs, resulting in a discrepancy between the beauty serum concentration and the actual needs of the skin. Ultimately, this affects the accuracy and effectiveness of the beauty treatment. In addition, the existing devices directly dispense thin, watery beauty serum, which is not only prone to loss and waste, but also difficult to penetrate the gaps in the stratum corneum of the skin, resulting in low absorption efficiency of active ingredients. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing ultrasonic beauty devices cannot adjust the concentration of beauty serum according to the user's skin type, resulting in a cumbersome beauty process and difficulty in fully realizing the effectiveness of ultrasonic beauty, and to propose a handheld ultrasonic beauty device.

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

[0007] The atomizing mechanism includes a storage cylinder fixed inside the handle, a partition fixed inside the storage cylinder, a micro pump fixedly installed inside the handle, a proportional valve provided between the micro pump and the storage cylinder, an ultrasonic generator b fixedly installed inside the probe, a flow guiding unit provided inside the connecting shell, and an adjustment component and a flow direction control unit provided between the flow guiding unit and the connecting shell.

[0008] The flow guiding unit includes a flow guiding shroud, and a baffle is fixed to the edge of the flow guiding shroud;

[0009] When the flow guide is suspended, the beauty liquid is diverted, and the ultrasonic generator b accelerates the atomization of the beauty liquid; when the flow guide is in contact with the ultrasonic generator b, 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 recessed, and the distance from the ultrasonic focusing point to the surface of the ultrasonic generator b is the same as the height of the guide shroud.

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

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

[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: the bottom of the flow guide is provided with a through hole, and the support plate seals the bottom through hole of the flow guide.

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

[0016] As a further description of the above technical solution: the control component 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 and the annular shell are connected, and the bottom of the storage box is in contact with the outside of the probe.

[0018] In summary, due to the adoption of the above-mentioned technology in this handheld ultrasonic beauty device, the beneficial effects of this invention are:

[0019] Firstly, the mixing system constructed by this application using a micro-pump and a proportional valve can dynamically adjust the concentration of the beauty serum in real time during the operation of the ultrasonic beauty device. Based on the user's immediate skin needs (such as the need for low irritation for dry and sensitive skin, and the oil control intensity for oily skin) and changes in the scene (skin water-oil imbalance caused by seasonal changes, and the need for barrier protection during the post-medical aesthetic repair period), it can precisely control the mixing ratio of concentrated beauty serum and solvent, so that highly active ingredients (such as anti-aging peptides and antioxidants) can act on the skin at the most suitable concentration, avoiding the blind spots of traditional fixed-concentration products. On this basis, the ultrasonic generator can also convert the mixed beauty serum into nano-sized droplets, significantly improving the transdermal absorption rate and thus enhancing the beauty effect.

[0020] Secondly, this application can not only divert the beauty liquid through the flow guiding unit to promote the atomization of the beauty liquid by the ultrasonic generator b, but also avoid the situation where the effective contact area between the beauty liquid and the ultrasonic generator b decreases during the handheld movement of the ultrasonic beauty device. This ensures that the ultrasonic generator b can continuously and evenly atomize and output the beauty liquid to the human body, thereby improving the effect of the beauty device.

[0021] Furthermore, through the coordinated operation of the flow guiding unit, adjustment components, and flow control unit, the ultrasonic generator b can utilize the ultrasonic cavitation effect to chemically reconstruct the beauty serum containing oily, macromolecular, and encapsulated components. Afterward, the beauty serum can directly penetrate the skin upon atomization without the need for secondary emulsification or diffusion, thus maximizing the effectiveness of the beauty serum.

[0022] Thirdly, this application, through its additional structure, not only enables the application of viscous beauty liquids (such as gels, creams, high-concentration essences, etc.) during the use of the beauty device, but also allows the viscous beauty liquid to be fully mixed with the atomized solvent when it flows out, thereby controlling the viscosity of the beauty liquid and improving its uniformity, penetration efficiency, and beauty effect.

[0036] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a handheld ultrasonic beauty device of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort 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 device, including a handle 10, a connecting shell 11 fixed to one end of the handle 10, a stainless steel probe 12 fixed to the open end of the connecting shell 11, and an ultrasonic generator a13 fixedly installed inside the probe 12. After the ultrasonic generator a13 is activated, it transmits vibration to the human body through the probe 12. Under the action of vibration, the human body accelerates the absorption of beauty fluid and achieves beauty effect.

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

[0039] Reference Figure 4 and Figure 5 The interior of the connecting shell 11 is provided with a flow guiding unit 26, which includes a flow guiding cover 261. The flow guiding cover 261 is conical and has several flow channels arranged at equal intervals around its center point. Through the multiple flow channels, the beauty liquid can be evenly dispersed into multiple streams and then come into contact with the ultrasonic generator b25. This allows the beauty liquid to fully disperse when it comes into contact with the ultrasonic generator b25, increasing the contact area with the ultrasonic generator b25 and thus accelerating the vibration atomization of the beauty liquid.

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

[0041] Reference Figure 4 , Figure 5 and Figure 6An adjustment component 27 and a flow direction control unit 28 are provided between the flow guiding unit 26 and the connecting shell 11. The adjustment component 27 includes a fixed cylinder 271 fixed inside the connecting shell 11 and connected to the outlet of the micro pump 23. An external connecting pipe 272 is movably connected inside the fixed cylinder 271. 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 guiding cover 261 can be adjusted, thereby adjusting the position of the beauty liquid sprayed from the flow guiding cover 261 onto the ultrasonic generator b25. When the output volume of the beauty liquid is low, the flow guiding cover 261 is lowered so that the sprayed beauty liquid is closer to the center position of the ultrasonic generator b25. Since the amount of beauty liquid sprayed decreases and the ultrasonic generator b25 vibrates stronger when it is closer to the center position, the beauty liquid can be vibrated and atomized faster, ensuring the output speed of the beauty liquid.

[0042] The flow control unit 28 includes an inner connecting pipe 281 movably connected inside the outer connecting pipe 272. The telescopic end of the electric telescopic rod 274 is fixed with a support plate 282. A spring 273 is provided on the top of the outer connecting pipe 272. The telescopic extension 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 flow guide shroud 261 can maintain contact with the support plate 282 under the elastic force of the spring 273.

[0043] Considering that the ultrasonic beauty device needs to be held in hand, it is inevitable that the device will be tilted during use. In order to maintain stable contact between the beauty liquid and the ultrasonic generator b25 and to ensure stable atomization output of the beauty liquid, a baffle 262 is fixed to the edge of the flow guide 261. The electric telescopic rod 274 is extended to move the support plate 282 downward. The elastic force of the spring 273 drives the external connecting tube 272 and the flow guide 261 downward until the bottom of the flow guide 261 contacts the ultrasonic generator b25. At this time, under the effect of the baffle 262 restricting backflow and guiding flow, the beauty liquid sprayed from the flow channel of the flow guide 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 beauty serums containing oily, macromolecular, or encapsulated ingredients, to ensure the beauty device fully utilizes the serum's effects, the bottom of the flow guide hood 261 has a through hole. The support plate 282 seals the bottom through hole of the flow guide hood 261, and a sealing ring is fixed to the bottom of the flow guide hood 261. When the flow guide hood 261 contacts the ultrasonic generator b25 and is sealed between them by the sealing ring, the spring 273 applies a downward elastic force to the flow guide hood 261, maintaining the sealed state between the flow guide hood 261 and the ultrasonic generator b25. The electric telescopic rod 274 extends, causing the support plate 282 and the inner connecting tube 281 to move downwards. The support plate 282 opens the bottom through hole of the flow guide hood 261, and the inner connecting tube... 281 seals the flow channel of the flow guide 261. At this time, the beauty essence output by the micro pump 23 enters the space between the flow guide 261 and the ultrasonic generator b25 through the fixed cylinder 271, the external connecting pipe 272 and the internal connecting pipe 281 until the liquid level rises to the height of the through hole. At this time, the ultrasonic generator b25 is activated. The ultrasonic generator b25 performs chemical reconstruction of the beauty essence through the ultrasonic cavitation effect. After the liquid level of the beauty essence continues to rise, it enters the flow channel of the flow guide 261 through the through hole and then flows out and comes into contact with the ultrasonic generator b25. Under the vibration of the ultrasonic generator b25, it is atomized. At this time, the output can directly penetrate the skin after contact without secondary emulsification or diffusion, so as to give full play to the effect of the beauty essence.

[0045] The recessed ultrasonic generator b25 focuses the ultrasonic waves. The distance from the point of ultrasonic focusing to the surface of ultrasonic generator b25 is the same as the height of the flow guide shroud 261. After the inner connecting tube 281 descends to near the surface of ultrasonic generator b25, the beauty liquid input by the micro pump 23 through the inner connecting tube 281 between the flow guide shroud 261 and ultrasonic generator b25 will flow from bottom to top, from the bottom with a larger diameter to the top with a smaller diameter of the flow guide shroud 261. The recessed ultrasonic generator b25 will focus the ultrasonic waves at the small diameter of the top of the flow guide shroud 261, making full use of the ultrasonic cavitation effect to vibrate, break up and mix the beauty liquid that is about to flow out through the through hole and the flow channel, so as to improve the use effect of the beauty liquid.

[0046] To further improve the atomization rate of the beauty liquid after diversion by the flow guide shroud 261 and the effect of chemical reconstruction of the beauty liquid using ultrasonic cavitation, an impeller 29 is fixedly connected to the inner wall of the inner connecting pipe 281. When the support plate 282 contacts the flow guide shroud 261, the flow guide shroud 261 is suspended. When the beauty liquid delivered by the micro pump 23 passes through the inner connecting pipe 281, it drives the impeller 29 to rotate the inner connecting pipe 281 and the support plate 282. The support plate 282 drives the flow guide shroud 261 and the outer connecting pipe 272 to deflect through friction, further atomizing the flow from the flow channel of the flow guide shroud 261. The flowing beauty liquid can be dispersed and dripped onto the ultrasonic generator b25, improving atomization efficiency. When the tray 282 is not in contact with the guide shroud 261, the guide shroud 261 is in contact and sealed with the ultrasonic generator b25. When the beauty liquid delivered by the micro pump 23 passes through the inner connecting pipe 281, it drives the impeller 29 to rotate the inner connecting pipe 281 and the tray 282. A baffle is fixed at the bottom of the tray 282. The baffle agitates the beauty liquid between the guide shroud 261 and the ultrasonic generator b25, and assists the cavitation effect to further improve the use effect of the beauty liquid.

[0047] Reference Figure 8 and Figure 9 When the flow guide 261 is suspended in the air, it diverts the beauty liquid. The diverted beauty liquid is sprayed onto the top surface of the ultrasonic generator b25 near the edge. Then, as it flows from the surface of the ultrasonic generator b25 towards the center, it is accelerated and atomized by ultrasonic vibration. When the flow guide 261 and the ultrasonic generator b25 are in contact, the space between the flow guide 261 and the ultrasonic generator b25 is filled with beauty liquid. At this time, a large amount of beauty liquid gathers between the flow guide 261 and the ultrasonic generator b25, and the ultrasonic generator b25 cavitates and mixes the beauty liquid.

[0048] Reference Figure 3 To enable the device to be used with viscous beauty liquids, an additional structure 30 is included. The additional structure 30 includes a storage box 31 for storing viscous beauty liquid, which is threaded to the outside of the handle 10. The storage box 31 is easy to disassemble for cleaning of residual beauty liquid inside. An annular shell 32 is slidably connected inside the storage box 31. An elastic cover 33 is installed at the bottom of the annular shell 32, and a control component 34 is provided at the top of the annular shell 32. The probe 12 and the annular shell 32 are connected. When 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 bottom outlet 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 inside the probe 12 will enter the annular shell 32 and contact the flowing beauty liquid to adjust the viscosity of the beauty liquid. When the bottom of the storage box 31 contacts the outside of the probe 12, 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 component 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 that is threadedly connected to the connecting rod 341. Tightening the two nuts 342 drives the connecting rod 341 to move up or down through the threads, thereby raising or lowering the annular shell 32 and controlling the outflow of beauty liquid inside the storage box 31.

[0050] Working principle: When using an ultrasonic beauty device in conjunction with a diluted, watery beauty serum, concentrated beauty serum and diluent are poured into two separate spaces in the storage cylinder 21, separated by a partition 22, through the inlet tube. The ratio of concentrated beauty serum to diluent is adjusted by the proportion valve 24 according to the user's skin type and actual needs, diluting the beauty serum to a suitable concentration range. After the user lies down, the micro pump 23, ultrasonic generator b25, and ultrasonic generator a13 are activated. The probe 12 is then placed on the desired area for treatment. The vibration generated by the ultrasonic generator a13 is transmitted to the skin through the probe 12. The micro pump 23 delivers the beauty essence through the channels of the fixed cylinder 271, the outer connecting pipe 272, the inner connecting pipe 281, and the flow guide 261 to the probe 12. The beauty essence sprayed out of the channels drips onto the edge of the surface of the ultrasonic generator b25 and flows towards the concave center of the ultrasonic generator b25. During this process, the ultrasonic generator b25 atomizes the beauty essence through ultrasonic vibration. The atomized beauty essence is sprayed out through the bottom outlet of the annular shell 32 and the storage box 31 to the space between the elastic cover 33 and the probe 12, and comes into contact with the user's skin. The probe 12 uses ultrasound to make the beauty essence fully absorbed by the skin to achieve the beauty effect.

[0051] When the beauty liquid passes through the inner connecting tube 281, it will drive the impeller 29, which will drive the inner connecting tube 281, the support plate 282 and the guide shroud 261 to rotate, so that the beauty liquid flowing out of the guide shroud 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, macromolecular, or encapsulated ingredients, before the ultrasonic generator b25 is activated, the electric telescopic rod 274 extends, causing the support plate 282 and inner connecting tube 281 to move downwards. The extension force of the spring 273 causes the outer connecting tube 272 and the flow guide 261 to move downwards synchronously with the support plate 282. After the flow guide 261 contacts and seals with the ultrasonic generator b25, the electric telescopic rod 274 extends, causing the support plate 282 and inner connecting tube 281 to continue moving downwards. This causes the support plate 282 to open the bottom through-hole of the flow guide 261, and the inner connecting tube 281 to close the flow channel of the flow guide 261. At this time, the micro pump 23 delivers... The extracted beauty essence enters the space between the flow guide 261 and the ultrasonic generator b25 through the fixed cylinder 271, the outer connecting pipe 272, and the inner connecting pipe 281 until the liquid level rises to the height of the through hole. The ultrasonic generator b25 is then activated to vibrate and mix the beauty essence through the ultrasonic cavitation effect. Afterward, the beauty essence continues to be delivered between the flow guide 261 and the ultrasonic generator b25 through the micro pump 23. As the liquid level continues to rise, it enters the flow channel of the flow guide 261 through the through hole and then flows out to contact the ultrasonic generator b25. Under the vibration of the ultrasonic generator b25, it is atomized. The atomized beauty essence can directly penetrate the skin after contact, fully exerting the effect of the beauty essence.

[0053] During this process, the beauty liquid flowing through the inner connecting pipe 281 is also driven to rotate by the impeller 29, which drives the inner connecting pipe 281 and the tray 282 to rotate. Since the tray 282 does not contact the flow guide 261, the flow guide 261 does not rotate at this time. The rotation of the tray 282 stirs the beauty liquid through the bottom baffle, further improving the mixing effect of the beauty liquid.

[0054] When using this beauty device with a viscous beauty serum, pour the beauty serum into the storage box 31 and the solvent into the storage cylinder 21. At this time, the bottom of the annular shell 32 is in contact with the bottom of the inner wall of the storage box 31. The beauty serum inside the storage box 31 is blocked by the annular shell 32 and will not flow out through the bottom outlet of the storage box 31. When using the beauty device, turn the two nuts 342 to drive the connecting rod 341 upward through the threads, which will raise the annular shell 32 and open the bottom outlet of the storage box 31. The beauty serum 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 come into contact with the flowing beauty serum to adjust the viscosity of the beauty serum. 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 serum.
