Description

Technical Field

[0001] This invention relates to the field of hair care equipment technology, and more particularly to a styling tool that can monitor and display the concentration of charged particles. Background Technology

[0002] Currently, high-speed hair dryers (styling tools) commonly integrate various ion generators to enhance hair care effects, such as negative ion generators, plasma generators, and water ion generators. These devices can generate various charged particles, including negative ions, positive and negative ions, and nano-water ions. However, existing technology has the following two significant gaps: 1. Lack of in-situ real-time sensing capability: Existing hair dryers only have various ion generating devices, but no sensing units are configured for these devices. The actual concentration of the generated ion particles and whether they are working effectively cannot be known in real time at the device. Users cannot confirm whether hair-care ions are actually generated or whether the concentration meets the standards, relying entirely on the manufacturer's claims. This creates an information black box, forcing users to passively believe the manufacturer's claims without being able to witness the effects of hair-care ion generation firsthand. Related concentration testing can only be performed in a laboratory environment using professional instruments, making it difficult to apply to consumer-grade products.

[0003] 2. Lack of integrable charged particle sensors: Although existing hair dryers have integrated various sensors such as temperature and distance as detection units, there is currently no sensor on the market that can directly detect charged particles. This sensor, which can be miniaturized and integrated directly into the confined, high-temperature, high-humidity, and high-speed airflow duct inside the hair dryer, is a non-functional device. This has resulted in this product category being in a state of "occurrence without monitoring" for a long time.

[0004] 3. Inability to distinguish the working status of different ions: When a molding machine is equipped with multiple ion generating devices (such as negative ions, plasma, and water ions), the existing technology cannot provide a means to monitor different types of ions separately, and cannot determine whether a specific device is working properly or has failed.

[0005] 4. Unpredictable failure of ion generator: During use, ion generators may gradually degrade or even fail due to dust accumulation, oxidation, electrode aging, etc. Existing styling tools lack self-diagnostic capabilities, and the fault can only be noticed by users after the hair care effect has obviously decreased.

[0006] 5. Disconnect between laboratory testing and consumer products: Current ion concentration detection relies on professional laboratory instruments, which cannot be integrated into consumer-grade styling tools, and cannot achieve real-time online monitoring.

[0007] Therefore, a completely new overall design architecture is urgently needed to integrate the missing charged particle sensing capability into the modeler and form a complete closed loop from separate detection, separate processing to separate visualization feedback. Summary of the Invention

[0008] In view of the above-mentioned problems in the prior art, a modeler that can monitor and display the concentration of charged particles is provided. It aims to make the particle concentration visible and to monitor the health status of the generator. The system architecture is simple and reliable, the device has a higher level of intelligence, and it is conducive to the expansion of product platforms, thereby improving the user experience and overcoming at least one of the above-mentioned technical defects.

[0009] The specific technical solution is as follows: A modeler capable of monitoring and displaying the concentration of charged particles includes a main body, the main body having at least one generator for generating charged particles and a display module.

The main body of the device also has a number of sensing modules that correspond one-to-one with the generator. The sensing electrode of each sensing module is adjacent to the particle release end of the corresponding generator to detect the concentration of charged particles in real time and generate particle concentration data, which is then displayed on the display module. When the particle concentration data is lower than a preset value, the corresponding generator is determined to be abnormal, and the display module displays a reminder message.

[0010] Preferably, the main body of the device also has a main control circuit board, and the display module, generator and sensing module are electrically connected to the main control circuit board. The main control circuit board has a main control MCU, which is configured to control the sensing module to charge the sensing unit with a predetermined polarity charge in a single particle concentration detection cycle, so as to neutralize the charged particles of the corresponding polarity generated by the generator and measure the particle concentration data.

[0011] Preferably, the sensing module includes a module housing with a built-in module circuit board, the module circuit board having a capacitor and a sensing electrode arranged facing the generator, and the capacitor and the sensing electrode together serve as a sensing unit, the sensing electrode being at least partially exposed outside the module housing and adjacent to the particle release end of the corresponding generator.

[0012] Preferably, the module circuit board also includes a module MCU, and the concentration detection process of the sensing module includes: S1, the main control MCU or module MCU control module circuit board charges the capacitor to the reference voltage, causing the sensing electrode surface to carry a known amount of charge; S2, charging stops, the sensing electrode is in a high-resistance suspended state, the charged particles generated by the generator flow directly over the surface of the sensing electrode, and a neutralization reaction occurs due to Coulomb force, causing the capacitor to lose charge proportional to the amount of charge of the charged particles; S3, after the neutralization reaction window ends, the main control MCU or module MCU immediately detects the residual voltage of the capacitor and calculates the total amount of charge neutralized in this cycle according to the formula ΔQ=C×(U0-U1), and then calculates the local ion concentration value generated by the generator.

[0013] Preferably, the sensing electrode is formed by one plate of a capacitor or part of the casing.

[0014] Preferably, when multiple generators are configured, each sensing module independently and in parallel acquires data, and each sensing module independently outputs the ion concentration value of its corresponding generator.

[0015] Preferably, the main control MCU reads particle concentration data from each sensing module in parallel via a digital interface, and processes each particle concentration data separately. The data processing program includes: Obtain the raw concentration values ​​measured by each sensing module in real time; A correction process is performed on the raw real-time concentration values ​​to obtain the corrected concentration values ​​for each particle. The corrected particle concentration values ​​are transmitted to the display module; Furthermore, if any generator has been turned on for more than a preset time and its corresponding corrected particle concentration value remains lower than the preset value, the generator is determined to be abnormal or faulty, and a fault code is generated.

[0016] Preferably, the main control MCU also has a correction processing program for the detection results of each channel, and the process of the correction processing program includes at least one of the following: The test results of each channel are converted and corrected according to the calibration curve written at the factory. Environmental drift compensation is performed on the detection results of each path based on the real-time collected temperature and humidity data; Electrode aging compensation gain adjustment is performed based on the cumulative working time of each sensing module; The self-calibration process is executed during power-on or under specific conditions to measure the background noise value of each sensor module and subtract it respectively.

[0017] Preferably, the main control MCU also has a calibration process for each sensing module, and the calibration process includes: With all generators off, the sensing module performs several cycles of detecting the concentration of charged particles in the environment, measures the background noise value of the current environment, and uses it as a zero-point reference.

[0018] Preferably, the sensing module and the corresponding generator are installed independently of each other, and there is a gap of 1 to 50 mm between the sensing electrode of the sensing module and the particle release end of the generator.

[0019] The beneficial effects of the above technical solution are as follows: (1) The modeler that can monitor and display the concentration of charged particles includes a main body, a display module, and an equal number of generators and sensing units. The generator is used to generate negative ions and / or plasma and / or water ions. The sensing unit is used to detect the particle concentration in real time, so that the specific concentration values ​​and status information of each ion can be directly displayed on the display module. It can also determine whether the working status of the generator is abnormal or damaged and needs maintenance based on the comparison between the concentration value and the preset value, so as to achieve the purpose of independent detection of multiple types of ions and visualization of concentration. It can also monitor the health status of the generator. The system architecture is simple and reliable, the equipment has a higher level of intelligence, and it is conducive to the platform expansion of the product, making the user experience better.

[0020] (2) The sensing electrode is composed of one plate of a capacitor or part of the outer shell, which can eliminate the connecting wires between the independent electrode and the capacitor, greatly reduce parasitic parameter interference, and enable the sensing unit to exist in the form of a standard surface mount component, which is convenient for SMT mounting in the small space of the molder, further reducing material costs and assembly complexity.

[0021] (3) Users can intuitively see whether the various ions such as negative ions, plasma, and water ions are working effectively, which enhances product trust and technological awareness and greatly improves user experience; the whole machine has the ability to sense ion function and diagnose faults, which facilitates after-sales maintenance and usage reminders, reduces user complaints caused by ion function failure, and improves the intelligence level of the equipment; each sensing channel is independent and parallel, without the need for complex timing separation or mixed detection strategies, and is calibrated and solidified before leaving the factory, so there is no need for dynamic adjustment during the use of the whole machine, which reduces the complexity of the system and makes the system architecture simple and reliable; the one-to-one matching modular architecture can flexibly adapt to different configurations of molders, which facilitates product line extension and upgrade, and is conducive to product platform expansion.

[0031] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. Figure 1 Specifically, this is a layout diagram for detecting the concentration of charged negative ions and plasma. Figure 2 and Figure 3 All are layout diagrams for detecting the concentration of charged water ions, and Figure 2 The diagram shows the layout of the water ion modules positioned in the middle of the air duct. Figure 3 The diagram shows the arrangement of water ion modules along the outer side of the ventilation duct.

[0032] See Figures 1 to 9 As shown in the figure, the modeler provided in this embodiment, capable of monitoring and displaying the concentration of charged particles, includes a main body 1. The main body 1 has at least one generator 2 for generating charged particles and a display module 4. The charged particles generated by the generator 2 include at least one of negative ions, positive and negative charged particles in plasma, and nano-water ions, which are used to output high-speed airflow and charged particles at the air outlet of the main body 1; wherein, The main body 1 also has a number of sensing modules 3 that correspond one-to-one with the generator 2. The sensing electrode of each sensing module 3 is adjacent to the particle release end of the corresponding generator 2, which is used to detect the concentration of charged particles in real time and form particle concentration data to be displayed on the display module 4. When the particle concentration data is lower than a preset value, the corresponding generator 2 is determined to be abnormal, and the display module 4 displays a reminder message.

[0033] Based on the above technical solution, the modeler capable of monitoring and displaying the concentration of charged particles includes a main body 1, a display module 4, and an equal number of generators 2 and sensing units. The generators 2 are used to generate negative ions and / or plasma and / or water ions, and the sensing units are used to detect the particle concentration in real time. This allows the display module 4 to directly display the specific concentration values ​​and status information of each ion. It can also determine whether the working status of the generators 2 is abnormal or damaged and requires maintenance based on the comparison between the concentration values ​​and preset values. This achieves the purpose of independently detecting multiple types of ions and visualizing their concentrations, and can monitor the health status of the generators 2. The system architecture is simple and reliable, the equipment has a higher level of intelligence, and it is conducive to the expansion of the product platform, resulting in a better user experience.

[0034] It is worth noting that placing the sensing electrode of the sensing module 3 near the particle release end of the corresponding generator 2 allows the charged particles generated by the generator 2 to flow directly over the surface of the corresponding sensing electrode, rather than being located near the outlet of the airflow channel within the main body 1 (i.e., downstream of the generator 2). This would easily cause particles to diffuse within the airflow channel, affecting the detection of the actual concentration. Without the need for an additional drainage channel, this design enables more accurate and reliable detection. Furthermore, unlike existing solutions where the sensing module 3 detects particle concentration in the user's hair or the external environment, this solution directly detects the particle concentration at the particle release end of the generator 2, directly determining the health status of the generator 2 (whether the concentration of released charged particles falls within the range between the lower and upper limits of a preset value).

[0035] In a preferred embodiment, the main body 1 also has a main control circuit board. The display module 4, the generator 2, and the sensing unit are electrically connected to the main control circuit board 5. The main control circuit board 5 has a main control MCU 7. The main control MCU 7 is configured to control the sensing module 3 to charge the sensing unit with a predetermined polarity charge in a single particle concentration detection cycle, so as to neutralize the charged particles of the corresponding polarity generated by the generator 2 and measure the particle concentration data.

[0036] As a further preferred embodiment, combined with Figure 4 and Figure 5 As shown, the sensing module 3 includes a module housing 8 with a built-in module circuit board 9. The module circuit board 9 has a capacitor 10 and a sensing electrode 11 arranged facing the generator 2, and the capacitor 10 and the sensing electrode 11 together serve as the aforementioned sensing unit. The sensing electrode 11 is at least partially exposed outside the module housing 8 and adjacent to the particle release end of the corresponding generator 2. Furthermore, a module MCU 12 is also provided on the module circuit board 9. The concentration detection process of the sensing module 3 includes: S1, the main control MCU7 or module MCU12 controls the module circuit board 9 to charge the capacitor 10 to the reference voltage, causing the surface of the sensing electrode 11 to carry a known amount of charge; S2, charging stops, sensing electrode 11 is in a high-resistivity suspended state, charged particles (negative ions, positive ions, positive and negative charged particles in plasma, nano water ions, etc.) generated by generator 2 flow directly through the surface of sensing electrode 11, and an electric neutralization reaction occurs due to Coulomb force, causing capacitor 10 to lose charge proportional to the amount of charge of the charged particles. S3, after the neutralization reaction window ends, the main control MCU7 or module MCU12 immediately detects the residual voltage of capacitor 10, calculates the total amount of charge neutralized in this cycle according to the formula ΔQ=C×(U0-U1), and then calculates the local ion concentration value generated by generator 2.

[0037] As a further preferred embodiment, the sensing electrode 11 is formed by one of the plates or part of the casing of the capacitor 10. For example, a non-polar surface-mount capacitor with a metal casing is selected, with the metal casing internally connected to one of the plates and the externally exposed as the sensing electrode 11. Various charged particles, such as negative ions, positive and negative charged particles in plasma, and nano-water ions, directly undergo an electroneutralization reaction on the surface of the capacitor casing, consuming the charge stored in the capacitor itself. This design eliminates the connecting wires between the independent electrode and the capacitor, greatly reducing parasitic parameter interference, and allows the sensing unit to exist in the form of a standard surface-mount component, facilitating SMT mounting in the confined space of the molding machine, further reducing material costs and assembly complexity.

[0038] As a further preferred embodiment, when multiple generators 2 are configured, each sensing module 3 independently and in parallel collects data, and each sensing module 3 independently outputs the ion concentration value of its corresponding generator 2.

[0039] In a preferred embodiment, specifically as follows: Figures 7 to 9 As shown, the main control MCU7 reads particle concentration data from each sensing module 3 in parallel via a digital interface, and processes the particle concentration data from each channel separately. The data processing program includes: Obtain the raw concentration values ​​measured by each sensing module 3 in real time; A correction process is performed on the raw real-time concentration values ​​to obtain the corrected concentration values ​​for each particle. The corrected particle concentration values ​​are transmitted to display module 4; Furthermore, if any generator 2 has been turned on for more than a preset time and its corresponding corrected particle concentration value remains lower than the preset value, then the generator 2 is determined to be abnormal or faulty, and a fault code is generated.

[0040] Specifically, the preset value can be a range with an upper threshold and a lower threshold. Generally, if the concentration value of the dedicated sensing module of the generator 2 after correction is still lower than the inherent lower threshold of the device for a preset time period, such as 30s, 1min or 5min, the device is judged to be malfunctioning and a fault code is generated.

[0041] In addition, based on the fault code, the main control MCU can also automatically adjust the voltage (current) of the control generator corresponding to the observed value to make the particle generation concentration fluctuate within a preset range in order to execute the self-repair program.

[0042] As a further preferred embodiment, the main control MCU7 also has a correction processing program for the detection results of each channel, and the process of the correction processing program includes at least one of the following: The test results of each channel are converted and corrected according to the calibration curve written at the factory. Environmental drift compensation is performed on the detection results of each path based on the real-time collected temperature and humidity data; Electrode aging compensation gain adjustment is performed based on the cumulative working time of each sensing module 3; The self-calibration process is executed during power-on or under specific conditions to measure the background noise value of each sensor module and subtract it respectively.

[0043] Specifically, to ensure the long-term accuracy and consistency of ion concentration detection results, the above-mentioned correction measures mainly include the following: Factory baseline calibration: Before leaving the factory, each molding unit is calibrated at multiple points using a standard ion source and standard detection instruments to check the output values ​​of each sensing module 3 under different concentration environments. A concentration-output correspondence curve is established and written into the storage unit of the sensing module 3 or the main control MCU7 as the conversion benchmark for the detection results.

[0044] Environmental drift compensation: The sensing module 3 has a built-in or system-integrated temperature and humidity sensor to acquire the temperature and humidity of the working environment in real time. The main control MCU7 corrects the detection results in real time according to the preset temperature and humidity compensation curve to offset the impact of environmental changes on the charge neutralization reaction rate and capacitance characteristics.

[0045] Electrode aging compensation: With the accumulation of usage time, the surface of the sensing electrode 11 may experience a slight decrease in reaction efficiency due to oxidation or contamination. The main control MCU7 records the cumulative working time of the sensing module 3 and performs progressive compensation gain adjustment on the detection results according to the preset life decay curve.

[0046] Multi-module cross-verification (when multiple sensing modules 3 are configured): The main control MCU7 can compare the output values ​​of different sensing modules 3 located in adjacent positions within the same air duct. If the reading of a certain sensing module 3 deviates significantly from the statistical average of other modules, it is determined that the module may be abnormal, and the confidence level of that data is reduced or a maintenance reminder is triggered.

[0047] As a further preferred embodiment, the main control MCU7 also has a calibration process for each sensing module 3, the flow of which includes: With all generators 2 turned off, the sensing module 3 performs several cycles of detecting the concentration of charged particles in the environment, measures the background noise value of the current environment, and uses it as a zero-point reference.

[0048] The periodic self-calibration procedure is as follows: the system performs a self-calibration process once each time the modeler is powered on or when the user performs a specific operation. With all generators 2 turned off, the sensing module 3 performs several complete "charge-neutralize-detect" cycles to measure the background noise value of the current environment, which is used as the zero-point reference. Subsequent detection results are all subtracted from this background value to eliminate measurement errors caused by circuit drift.

[0049] In specific applications, as a styling tool such as a hair dryer, it has a horizontal air barrel 13 and a vertical handheld part 14. An airflow channel is formed together within the air barrel 13 and the handheld part 14. The handheld part 14 also has a fan 15 for conveying high-speed airflow, and an air inlet 16 is correspondingly arranged on the lower side of the handheld part 14. For example... Figure 1 For example, an annular air outlet channel 17 is formed in the air duct 13, and a generator 2 for generating charged negative ions or plasma is arranged in the air outlet channel 17. The generator 2 is electrically connected to the main control circuit board 5 via a high-voltage transformer 6. A sensing module 3 is installed adjacent to the generator 2, with the sensing electrode 11 of the sensing module 3 facing the particle release end of the generator 2. The display module 4 is a display screen, which is arranged at the tail end of the air duct 13 (limited by the rear end cover). The display screen is electrically connected to the main control circuit board 5 through wires; for another example Figure 2 As shown, an installation cavity 18, isolated from the air outlet duct 17 and open to the front, is formed inside the air duct 13. A water ion generator is arranged inside the installation cavity 18. The water ion generator is also electrically connected to the main control circuit board 5 via a high-voltage transformer 6. A front cover plate with an outlet is installed at the front open end of the installation cavity 18. A sensing module 3 is embedded in the side of the front cover plate facing the water ion generator. The sensing module 3 is electrically connected to the main control circuit board 5 via a connecting wire harness to transmit information. For example... Figure 3 As shown, different Figure 2 The proposed scheme involves arranging the water ion generator 2 as follows: Figure 1 Within the similar annular air outlet channel 17, a sensing module 3 is arranged on its front side and connected to the circuit accordingly.

[0050] The air duct 13 can be configured with multiple mounting positions for installing generators 2 and corresponding sensing modules 3, allowing for the simultaneous installation of multiple different types of generators 2 to release one or more charged particles from negative ions, positive and negative charge particles in plasma, and nano-water ions at the air outlet, and to detect and determine the health status of each generator 2. Negative ion generator: This device ionizes air molecules through high-voltage corona discharge, producing negatively charged air ion particles, primarily composed of negative oxygen ions. It is typically installed inside the main air duct, with its release probe positioned horizontally within the air outlet duct.

[0051] Plasma generator: This device generates both positive and negative ions (i.e., plasma) through dielectric barrier discharge or corona discharge, containing both positively and negatively charged air ion particles. It is typically installed inside the main air duct, with a layout similar to that of a negative ion generator.

[0052] Water ion generator: This device generates nano-sized charged water ion particles that encapsulate water molecules or active substances through high-voltage electrostatic atomization or condensation technology. The charge polarity of these particles can be positive or negative, and their particle size is typically larger than that of ordinary air negative ions. This device is independent of the main air duct and releases the nano-water ions into the external space of the air duct 13 through a separate release port.

[0053] The charged particles generated by the above-mentioned generating devices all share the common characteristic that they carry a net charge, and therefore can all induce an electric neutralization reaction on the surface of the sensing electrode 11 of the sensing module, thereby being quantitatively detected.

[0054] Because the water ion generator is located in an independent space outside the air duct 13, while the negative ion generator and plasma generator are located inside the main air duct, the various charged particles generated by each device are spatially isolated and will not mix before detection. Therefore, the monitoring strategy of this invention is that each sensing module operates independently and in parallel. Each ion generator is equipped with a dedicated ion concentration sensing module, and the two are configured in a one-to-one pair. Each sensing module independently executes the "charging-neutralizing-detection" cycle without interference, and outputs the concentration value of the corresponding ion type in real time. The main control MCU7 receives the concentration data from each sensing module in parallel, processes it, and drives the display of the corresponding information.

[0055] As another alternative, multiple generators 2 can be configured within the same air duct. When the type of charged ions being measured is not individually distinguished, the sensing module 3 can collect data on the charged ions generated by all generators within the same air duct in parallel and output the total ion concentration value of the corresponding generator within the air duct. That is, the sensing module 3 functions as a device for measuring the total ion concentration.

[0056] Specifically, in this solution, the negative ion generator / plasma generator is mainly arranged within the main air duct: the generator 2 release probe is located inside the main air duct, and the corresponding sensing module is fixedly installed downstream of the release probe. The distance between the surface of the sensing electrode 11 and the release end is maintained between 1mm and 50mm, allowing the generated negative ions or positive and negative ions to flow directly through the electrode surface for detection. The sensing module and the generator can be independent of each other or integrated into a single architecture, with each using a fixed structure to ensure spacing accuracy.

[0057] For the water ion generator, a separate spatial layout outside the air duct 13 is mainly adopted: the water ion generating module is not located in the main air duct, and its nano-water ions are discharged through an independent release port. The release port can be set on the central axis of the unit or on the periphery outside the air duct 13. The corresponding sensing module is fixedly installed near the release port, with the sensing electrode 11 facing the release port directly, but the sensing electrode 11 and the release port can also correspond at a wide angle, as long as charged ion particles pass over the surface of the motor. The distance is maintained between 1mm and 50mm, allowing the nano-water ions to flow directly over the electrode surface for detection. The two can be independent of each other or integrated into a single architecture.

[0058] Furthermore, the particle concentration values ​​of all sensing modules 3 are calibrated before the device leaves the factory, and the detection parameters are fixed in the configuration, requiring no dynamic adjustment during use. The output values ​​of each sensing module are calibrated under different concentration environments using a standard ion source and standard detection instruments, establishing a concentration-output correspondence curve. Key parameters such as the detection window time and charging voltage of sensing modules 3 have been determined as fixed optimal values ​​during the R&D phase and are fixed in the hardware or firmware. During mass production, this fixed configuration is directly written into every unit, allowing end users to obtain accurate concentration readings without any dynamic adjustments.

[0059] In a preferred embodiment, the sensing module 3 and the corresponding generator 2 are installed independently of each other, and there is a distance of 1 to 50 mm between the sensing electrode 11 of the sensing module 3 and the particle release end of the generator 2. However, they can also be configured as a whole module in the modeler, and the above-mentioned distance can be changed according to the requirements and is not limited thereto.

[0060] As a further preferred embodiment, the display module 4 is an LED display screen or an OLED display screen, and the display module 4 has a concentration information bar that is independently set for each generator 2, so as to display the type name of the charged particles and their concentration value in real time; and when the main control MCU7 determines that a generator 2 is faulty, it displays a fault prompt text in the corresponding concentration information bar.

[0061] Based on the above technical solutions, users can intuitively see whether various ion channels, such as negative ions, plasma, and water ions, are working effectively, enhancing product trust and technological awareness, and significantly improving the user experience. The entire machine has self-sensing and self-diagnostic capabilities for ion functions, facilitating after-sales maintenance and usage reminders, reducing user complaints caused by ion function failures, and improving the intelligence level of the equipment. Each sensing channel operates independently and in parallel, eliminating the need for complex timing separation or mixed detection strategies. Calibration and solidification are completed before leaving the factory, eliminating the need for dynamic adjustments during use, reducing system complexity, and making the system architecture simple and reliable. The one-to-one modular architecture can flexibly adapt to different configurations of shapers, facilitating product line extension and upgrades, and promoting product platform expansion.

[0062] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
