Description

Technical Field

[0001] This invention belongs to the field of beauty equipment technology, specifically relating to a Huihao ion excitation device for beauty purposes. Background Technology

[0002] Waste electronic products, also known as e-waste or electronic waste, mainly include discarded household appliances, computers, mobile phones, and other electronic products. If these products are not properly disposed of after they are discarded, they will place a significant burden on the environment. Therefore, they need to undergo professional recycling and processing to reduce their environmental impact. Waste electronic products contain a large amount of precious metals and other valuable materials, such as gold, silver, and copper. Through scientific recycling and refining, these resources can be reused to create economic value.

[0003] In existing technologies, traditional ion generating devices suffer from poor uniformity of ion interaction and limited ion diversity due to electrode structure design and electric field distribution issues.

[0004] Common ion generators typically employ a structure with a single discharge electrode paired with a single receiving electrode. In this configuration, the ion flow generated by the discharge is primarily concentrated along the most direct path between the two electrodes, resulting in uneven ion distribution within the treatment area and difficulty in achieving broad and uniform coverage. More importantly, this structure, especially when using a ring-shaped receiving electrode, can itself hinder ion escape. Negative or positive ions are easily adsorbed by the ring-shaped high-voltage electrode or receiving electrode and cannot escape. This not only limits the types of ions ultimately released but also further exacerbates the non-uniformity of the ion field. Consequently, the effectiveness of beauty treatments can be significantly reduced due to fluctuations in ion concentration and type within the treatment area, failing to ensure a stable and consistent user experience. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a cosmetic ion stimulation device, aiming to solve the technical problem that the prior art cannot ensure a stable and consistent user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cosmetic ion excitation device, comprising a device housing, an ion excitation head disposed at the head of the device housing, the ion excitation head comprising an insulating base and an excitation electrode assembly fixed thereon, the excitation electrode assembly comprising a plurality of microelectrodes arranged in an array; an ion excitation circuit disposed inside the device housing, the ion excitation circuit comprising a high voltage generation module and an electrode driving module, the high voltage generation module being electrically connected to the electrode driving module, and the electrode driving module being connected to each microelectrode in the excitation electrode assembly via wires.

[0007] Furthermore, the microelectrode is made of platinum-iridium alloy or 316L stainless steel.

[0008] Furthermore, the array can be a concentric ring array or a rectangular array.

[0009] Furthermore, the ion excitation head is detachably connected to the head of the device housing.

[0010] Furthermore, the ion excitation circuit also includes a control module and a mode selection switch electrically connected to the control module, the control module being electrically connected to the electrode driving module.

[0011] Furthermore, the electrode driving module, under the control of the control module, can apply high-voltage pulses with different phases to different microelectrode subsets in the excitation electrode group.

[0012] Furthermore, a flow guide ring is provided around the ion excitation head, and the flow guide ring is fixedly connected to the insulating base.

[0013] Furthermore, the guide ring is made of polytetrafluoroethylene or ceramic.

[0014] Furthermore, a semiconductor cooling chip is also provided inside the device housing, and the cold end of the semiconductor cooling chip is thermally connected to the base region of the ion excitation head.

[0015] Furthermore, the surface of the device housing is provided with a temperature control switch electrically connected to the semiconductor cooling chip.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, an electrode array consisting of multiple independent microelectrodes arranged in a specific array is set on the ion excitation head, and the electrode driving module is connected to these microelectrodes separately. The array of multiple microelectrodes can physically form an ion excitation source with a wider coverage and denser distribution. When working simultaneously, they can generate multiple fine ion streams. These ion streams intertwine and complement each other in the target area, forming an extremely uniform ion field, thereby avoiding the "hot spots" or "blind spots" that may be generated by a traditional single electrode, ensuring the consistency of the cosmetic effect. Distributing electrical energy to multiple microelectrodes means that, while maintaining the overall output effect, the instantaneous operating voltage and current required by each microelectrode can be lower. This not only reduces the load on a single electrode and extends the device life, but more importantly, it reduces the risk of generating high-intensity, highly irritating arc discharge from the source, making the generated ion stream gentler and more stable, which is very suitable for beauty and skincare scenarios with extremely high safety requirements.

[0017] 2. In this invention, through the control module and the electrode driving module, high-voltage pulses with different phases can be applied to different subsets of microelectrodes. This means that the microelectrodes in the electrode group do not work simultaneously, but rather, like a flowing light, they are excited alternately in a specific order and timing. This strategy further optimizes the spatial uniformity problem through temporal control. The phase-alternating pulse driving mode is equivalent to "dynamically scanning" the ion excitation field within the action area. This can compensate for the microscopic non-uniformity that may exist even in fine arrays, achieving a leap from one-dimensional static coverage to four-dimensional spatiotemporal coverage, resulting in a higher level of uniformity. Continuous high-voltage discharge generates significant heat. By allowing the electrodes to work in turn, each microelectrode has a brief "rest period," providing a valuable heat dissipation window for the device. This effectively controls the overall temperature of the ion excitation head surface, preventing overheating during prolonged operation, thus avoiding potential burns or discomfort to the skin caused by high temperatures, greatly improving user comfort and safety.

[0018] 3. In this invention, a semiconductor cooling chip is integrated internally. Its cold end is directly thermally connected to the base area of ​​the ion excitation head, and user intervention is possible via a temperature control switch. Even with innovative electrode design and control strategies, the device may still accumulate heat under extreme usage conditions or high ambient temperatures. The integrated independent cooling module provides an active and efficient cooling method. It directly removes heat from key parts of the excitation head, complementing the intermittent heat dissipation driven by pulses, creating a dual temperature safety system combining passive and active cooling, fundamentally eliminating the risk of low-temperature burns. The semiconductor cooling chip continuously maintains the excitation head at a comfortable low temperature. This is not only for safety but also provides additional cosmetic benefits and a pleasant experience. Low-temperature contact helps shrink pores and soothe the skin, making it especially suitable for use in summer or for treating sensitive skin after phototherapy or skin resurfacing, achieving a synergistic effect of "ion therapy" and "physical cooling." Attached Figure Description

[0019] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0020] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0022] Example 1: Please see Figure 1 This embodiment provides the following technical solution: a cosmetic ion excitation device, including a device housing, an ion excitation head provided at the head of the device housing, the ion excitation head including an insulating base and an excitation electrode group fixed thereon, the excitation electrode group being composed of multiple microelectrodes arranged in an array; an ion excitation circuit is provided inside the device housing, the ion excitation circuit including a high voltage generation module and an electrode driving module, the high voltage generation module being electrically connected to the electrode driving module, and the electrode driving module being connected to each microelectrode in the excitation electrode group through wires.

[0023] Specifically, the device includes a housing, with an ion excitation head located at its head. The ion excitation head comprises an insulating base made of ceramic or special engineering plastic, and an excitation electrode assembly fixedly mounted on the insulating base. The excitation electrode assembly consists of at least ten microelectrodes, which are embedded or fixed in a precise array within the insulating base, with a spacing error between each microelectrode not exceeding 0.1 mm. An ion excitation circuit is housed inside the housing, mounted on a separate printed circuit board. The ion excitation circuit includes a high-voltage generation module and a multi-channel electrode driving module. The input of the high-voltage generation module is connected to the device's built-in power supply, and its output is electrically connected to the power input of the electrode driving module. The electrode driving module contains multiple independent output channels, the number corresponding to the number of microelectrodes. Each output channel is reliably electrically connected to a corresponding microelectrode pin via an independent microwire passing through a pre-embedded channel inside the insulating base.

[0024] By setting an excitation electrode group consisting of multiple microelectrodes arranged in an array in the ion excitation head, and connecting the electrode driving module to each microelectrode, a uniform and stable distribution of the ion excitation field in the action area is achieved, effectively overcoming the defect of uneven action of single-point electrodes and improving the consistency of nursing effect.

[0025] The microelectrodes are made of platinum-iridium alloy or 316L stainless steel.

[0026] The array can be either a concentric ring array or a rectangular array.

[0027] Specifically, the microelectrode is made of either platinum-iridium alloy or 316L stainless steel. When choosing platinum-iridium alloy, the platinum content should be no less than 90%, and the iridium content should be around 10%. This ratio optimally balances conductivity and resistance to spark erosion. If 316L stainless steel is used, its surface must be mirror-polished, with a surface roughness Ra value of no more than 0.2 micrometers, to reduce the discharge threshold and enhance corrosion resistance.

[0028] The array can be either a concentric ring array or a rectangular array. When using a concentric ring array, it contains at least three concentric rings with diameters of 2 mm, 5 mm, and 8 mm from the innermost to the outermost ring. Each ring has eight microelectrodes evenly spaced. When using a rectangular array, it is a matrix of 36 microelectrodes arranged in 6 rows and 6 columns, with a center-to-center distance of 1.5 mm between adjacent rows and columns.

[0029] By limiting the material of the microelectrodes to platinum-iridium alloy or 316L stainless steel, the electrodes are ensured to have excellent resistance to electro-erosion and biocompatibility when working in a high-voltage environment for a long time, thus guaranteeing the service life and safety of the device. By limiting the array to concentric rings or rectangles, the spatial distribution of electric field and ion flow is further optimized to adapt to different care sites and area requirements.

[0030] The ion excitation head is detachably connected to the head of the device housing.

[0031] Specifically, the ion excitation head is detachably connected to the head of the device housing via a quick-release mechanism. This quick-release mechanism consists of a male metal contact with a sealing ring at the tail of the ion excitation head, and a corresponding female connector with a built-in elastic probe at the head of the device housing. During connection, mechanical locking and circuit connection are achieved by inserting the male connector into the female connector and rotating it 30 degrees; reversing the rotation allows for easy disassembly.

[0032] By designing the ion excitation head to be detachably connected to the device housing, the excitation head can be easily replaced, cleaned, and disinfected, effectively preventing cross-infection. It also allows users to change to different sizes of excitation heads according to different skin care needs, improving the product's hygiene and functional flexibility.

[0033] The ion excitation circuit also includes a control module and a mode selection switch electrically connected to the control module. The control module is electrically connected to the electrode driving module.

[0034] The electrode driving module, under the control of the control module, can apply high-voltage pulses with different phases to different microelectrode subsets in the excitation electrode group.

[0035] Specifically, the ion excitation circuit also includes a control module centered around a microcontroller unit. This control module integrates firmware storing multiple operating modes. A mode selection switch is mounted on the outer wall of the device housing, and its signal output is electrically connected to the general-purpose input / output pins of the control module. The pulse width modulation output pin of the control module is electrically connected to the control input of the electrode drive module, used to send precise timing control signals to the electrode drive module.

[0036] Under the control of the control module, the electrode driving module can divide all microelectrodes into at least two logical subsets. The control module is programmed to apply a high-voltage pulse sequence with the same period but a phase difference of 180 degrees to subset A and subset B. That is, when one subset is in a high-level excitation state, the other subset is in a low-level sleep state, and the two work alternately.

[0037] By introducing a control module, a mode selection switch, and an electrode driving module to apply high-voltage pulses with different phases to the microelectrode subset, the device's operating mode is programmable and switchable, and a dynamically scanning ion field can be generated. This not only further optimizes the uniformity of action but also avoids localized continuous heating, improving energy utilization efficiency and user comfort.

[0038] A flow guide ring is provided around the ion excitation head, and the flow guide ring is fixedly connected to the insulating base.

[0039] The guide ring is made of polytetrafluoroethylene or ceramic.

[0040] Specifically, a flow guide ring is tightly fitted around the ion excitation head. This flow guide ring is mechanically connected and fixed to the outer thread of the insulating base via threads on its inner wall, or it is bonded to the insulating base with a high-temperature resistant medical-grade adhesive. The inner cavity of the flow guide ring has a tapered profile that gradually narrows towards the outlet direction, used to constrain and guide the ion gas flow.

[0041] The guide ring is made of polytetrafluoroethylene (PTFE) or high-purity alumina ceramic. If PTFE is used, its volume resistivity must be greater than 10 Ω·cm. 16 Ω·cm is used to ensure excellent insulation performance. If high-purity alumina ceramic is used, its alumina content should not be less than 95% to provide good surface smoothness and thermal stability.

[0042] By setting a guide ring around the ion excitation head and limiting the material of the guide ring, the ion flow generated by the excitation can be guided and concentrated, reducing the disorderly diffusion of ions in the environment and ensuring that ions are delivered to the target area more effectively. At the same time, the insulating structure also physically isolates the user's skin from the risk of direct contact with the high-voltage electrode, enhancing electrical safety.

[0043] The device housing also contains a semiconductor cooling chip, the cold end of which is thermally connected to the base area of ​​the ion excitation head.

[0044] The device housing has a temperature control switch electrically connected to the semiconductor cooling chip.

[0045] Specifically, a thermoelectric cooler is also installed inside the device housing. The cold end of the thermoelectric cooler is tightly attached to a metal heat sink via a layer of highly thermally conductive silicone grease. The metal heat sink is thermally connected to the metal base area of ​​the ion excitation head or to a metal heat sink embedded in the insulating base via screws. The hot end of the thermoelectric cooler is connected to an active cooling fan.

[0046] A temperature control switch is provided on the surface of the device housing. This temperature control switch is a potentiometer with a dial or a digital incremental encoder, which is electrically connected to the drive circuit of the thermoelectric cooler. By rotating the dial or encoder, the user can linearly or incrementally adjust the operating current of the thermoelectric cooler, thereby achieving stepless control of the cooling intensity.

[0047] By placing a semiconductor cooling chip inside the device housing and thermally connecting its cold end to the ion excitation head base, active cooling of the working area of ​​the excitation head is achieved, effectively neutralizing the Joule heat generated during electrode operation and avoiding skin burns or discomfort that may be caused by excessively high device head temperature. Combined with a temperature control switch, it gives users the autonomy to adjust the temperature according to their own feelings, significantly improving the safety and comfort of use.

[0048] Example 2: Please see Figure 1 In this embodiment, the staff uses the device disclosed in the present invention in a home nighttime skincare setting.

[0049] The user, a 30-year-old woman, took a device called the Crystal Ion Revitalizing Device from her vanity after cleansing her face. The device features an ergonomic, streamlined design with a matte white medical-grade ABS plastic casing, weighing only 120 grams and offering a comfortable grip. She lightly pressed the power button on the side of the device, and a small OLED screen above the handgrip lit up, indicating that the standard care mode was active. She adjusted the intensity to level three using a touch-sensitive slider embedded in the device's surface; the screen then displayed a target voltage of 3500 volts.

[0050] Inside the device, an STMicroelectronics STM32G030 series ARM Cortex-M0+ microcontroller acts as the control core, running a pre-installed skincare program. The microcontroller instructs a boost circuit based on the LMR16020 chip, which raises the 3.7V DC power supplied by the built-in Samsung INR18650-35E lithium-ion battery to 300V. This intermediate voltage is then fed into a miniature transformer controlled by a UCC27424 driver chip, further generating the required 3.5KV high-frequency pulse voltage, which is then delivered to a multi-channel electrode driver module.

[0051] At the heart of this driver module is a Texas Instruments SN74HC595 shift register, which works in conjunction with the microcontroller to divide all thirty-six platinum-iridium alloy microelectrodes arranged in a 6x6 rectangular array into four independent logical subsets. Each microelectrode is only 0.3 millimeters in diameter, with a precise spacing of 1.5 millimeters. Following the microcontroller's precise timing, the driver module cyclically applies positive pulses with sequentially delayed phases of 90 degrees to these four subsets at a frequency of 2 kilohertz. Microscopically, at any given minute instant, only one-quarter of the microelectrodes are in a discharging state, working in turn like a precise electronic ballet.

[0052] When the user gently presses the device's ceramic guide ring against their facial skin, these alternately activated microelectrodes generate a strong localized electric field around their tips. This electric field ionizes oxygen molecules in the surrounding air, generating a uniform glowing ion cloud rich in negative oxygen ions. Because the electrodes work alternately over time, the generated ion clouds superimpose in both time and space, forming a completely covered and stable ion field above the user's facial skin, without any irritation or missed areas.

[0053] Meanwhile, a TEC1-3106 semiconductor cooling chip inside the device begins operation. Its cold end is tightly bonded to the aluminum alloy base of the ion excitation head via a layer of Shin-Etsu X-23-7921-5 high thermal conductivity silicone grease, continuously transferring away the Joule heat generated by the electrodes. The heat from the hot end is forcibly expelled by a miniature centrifugal fan (model KF0520B1H3R) powered by a solar motor. The user sets the cooling temperature to 18 degrees Celsius using a digital encoder on the device, resulting in a cool and comfortable soothing sensation when the ceramic cooling ring comes into contact with the skin.

[0054] Throughout the 15-minute treatment, a gentle, even field of negative ions continuously acts on the skin's stratum corneum, helping to open pores and promote skin cell metabolism. When the program ends, the device emits a soft beep and automatically shuts off. Users touching their cheeks can clearly feel that their skin is more hydrated and plump than before the treatment, and their complexion is more even and radiant. The entire treatment experience is safe, comfortable, and highly effective, perfectly demonstrating the superior performance of the Huihao Ion Stimulation Device in home beauty settings.

[0055] The working principle of this invention is as follows: Step 1: The user selects the desired operating mode using the mode selection switch on the device casing. The signal is sent to the control module, which is typically a microcontroller. The microcontroller then retrieves the pre-programmed instruction set corresponding to the mode from its built-in memory, including parameters such as target voltage, pulse frequency, phase sequence, and cooling intensity.

[0056] Step 2: The control module sends a command to the high-voltage generation module. The high-voltage generation module starts up, converting the low-voltage DC power supplied by the built-in battery into a stable high-frequency AC voltage or pulsed DC voltage in the thousands of volts range through oscillation, boost, and rectification circuits. This initially generated high voltage is precisely controlled within a safe and effective range and then sent to the electrode drive module.

[0057] Step 3: The electrode driving module begins operation under the timing instructions of the control module. It does not simply distribute high voltage simultaneously to all microelectrodes. According to the innovative strategy protected in claim 6, the driving module divides the array of microelectrodes into several logical subsets and applies phase-interleaved high-voltage pulses to these subsets.

[0058] Specifically, at time T1, it may apply only a brief high-voltage positive pulse to subset A. At time T2, the pulse to subset A ends, and it immediately applies an identical pulse to subset B, but with a phase delay of 180 degrees. This "time-division ignition" mode cycles rapidly. From a macroscopic perspective, the entire electrode array is working, but on a microscopic timescale, only a portion of the electrodes are discharging at any given moment.

[0059] Step 4: When a subset of microelectrodes is subjected to a high-voltage pulse, an extremely strong non-uniform electric field is formed around its needle-like tip. This electric field is sufficient to "strip" electrons from air molecules around the device head, causing gas ionization and generating "Huihao ions" containing negative oxygen ions, active particles, etc. Because the electrodes are arranged in a high-density array and excited in an alternating phase manner, these instantaneously generated, discrete ion clouds will diffuse, intertwine, and merge with each other within the action area due to the concentration gradient and electric field force, ultimately forming a continuous, stable, and highly uniform bulk ion field that completely covers the skin surface, avoiding the non-uniformity problem of traditional single-point discharge.

[0060] Step 5: The conical structure on the inner wall of the guiding ring at the device head guides and concentrates the ion field, acting like a "nozzle" to direct the ion flow more concentratedly and orderly to the target skin area. Simultaneously, the semiconductor cooling chip activates, its cold end continuously absorbing and transferring Joule heat generated during electrode discharge and circuit operation from the base area of ​​the ion excitation head through heat-conducting components. This ensures that the contact surface between the excitation head and the skin, or adjacent areas, remains at a safe and comfortable low temperature. The generated radiant ions, in this cooled and uniform environment, ultimately act on the skin to achieve their preset beauty and skincare effects.

[0061] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
