Description

Technical Field

[0001] This invention relates to the field of health assistance technology, and in particular to a slow-wave hydration negative ion generator and health assistance device. Background Technology

[0002] With the fast pace of modern life, people are facing increasing pressure, and problems such as sleep disorders and anxiety are becoming more and more common. At the same time, with the aging population, how to effectively prevent and delay neurodegenerative diseases, such as Alzheimer's disease, has become a focus of attention in the medical and health fields.

[0003] Existing research indicates that interventions involving brainwaves at specific frequencies can have a positive regulatory effect on the human body. For example, isochronous impulse sounds in both ears (such as 40Hz impulse sounds) have been shown to synchronously induce gamma oscillations in the brain through the auditory cortex, helping to improve the brain microenvironment. In addition, binaural difference-frequency rhythms, by inputting sounds of different frequencies into the left and right ears, allow the brain to perceive the frequency difference, effectively inducing the brain to enter a state of relaxation, meditation, or deep sleep.

[0004] On the other hand, positively charged free radicals such as peroxide radicals (ROO·) can steal electrons from cells, causing oxidative damage and accelerating aging and neuroinflammation. Meanwhile, negative air ions (such as O2)... - (O2)2 - O3 - Negative ions (such as superoxide dismutase and glutathione) possess abundant free electrons and have a strong electron-donating ability. After entering the human body, negative ions can increase the activity of antioxidant enzymes such as superoxide dismutase (SOD) and glutathione (GSH), reduce the concentration of oxidative markers, and thus alleviate neurooxidative stress.

[0005] However, existing health aids are typically single-function, offering only audio-based sleep aids or only negative ion generation. The few devices that combine both often simply piece together a sound-generating module and a negative ion-generating module, resulting in bulky, complex designs that fail to achieve deep synergy between the two. For example, traditional negative ion generators usually require a dedicated fan to blow out negative ions, but the high-voltage discharge process can easily produce excessive ozone, posing a safety hazard. Summary of the Invention

[0006] The purpose of this invention is to provide a slow-wave hydration negative ion generator and health auxiliary device to solve the problems of existing devices having single functions, piecemeal structures, and lack of deep synergy.

[0007] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a slow-wave hydrated negative ion generator, comprising: a housing, the top of which is open, and an internal cavity formed therein; a metal mesh plate disposed at the open; a semiconductor cooling chip disposed within the cavity, the cooling or heating surface of the semiconductor cooling chip being thermally coupled to the metal mesh plate for forming a condensate film on the surface of the metal mesh plate or heating the metal mesh plate; a discharge assembly disposed within the cavity and opposite to the metal mesh plate, the discharge assembly being used for tip discharge under voltage drive; an acoustic vibration unit disposed on the side of the discharge assembly away from the metal mesh plate, the acoustic vibration unit being used to output brainwave intervention audio, and the vibration of the acoustic vibration unit being used to drive the gas in the cavity to be discharged outward; and a boost module disposed within the cavity for boosting the input operating voltage to the voltage required for the discharge assembly to discharge.

[0008] Furthermore, the discharge assembly includes a discharge circuit board and a circuit board support. The circuit board support is a hollow structure with a thickness greater than that of the discharge circuit board. The discharge circuit board is mounted on the top of the circuit board support, and the acoustic vibration unit is disposed outside the bottom of the circuit board support, so that a gap is left between the discharge circuit board and the acoustic vibration unit. The discharge circuit board includes: multiple discharge needles arranged in a ring array in a first region; multiple discharge carbon brushes arranged in a ring array in a second region, the second region being located on the periphery of the first region; and multiple first through holes for forming airflow channels.

[0009] Furthermore, the acoustic vibration unit includes a low-frequency horn and a horn resonant cavity, with the low-frequency horn disposed within the horn resonant cavity.

[0010] Furthermore, the generator also includes a heat sink, and the side of the semiconductor cooling chip away from the metal mesh plate is thermally coupled to the heat sink.

[0011] Furthermore, the bottom of the housing is provided with multiple second through holes to form an airflow channel and an audio output channel.

[0012] Furthermore, the metal mesh plate is a porous disc structure, and the aperture of the opening in the central region of the porous disc structure is smaller than that in the outer region.

[0013] Furthermore, the hydrated negative ion generator is configured as follows: In the first operating mode, the semiconductor cooling chip acts on the metal mesh plate with its cooling surface to form a water film on the surface of the metal mesh plate; the discharge needle tip discharges on the water film to generate hydrated negative ions; the discharge carbon brush discharges to generate ordinary negative ions; in the second operating mode, the semiconductor cooling chip acts on the metal mesh plate with its heating surface or remains in a closed state; the discharge needle tip discharges on the metal mesh plate to generate ozone.

[0014] Secondly, the present invention provides a health assistive device, comprising a controller, a first generator module, and a second generator module; the first generator module and the second generator module are slow-wave hydrated negative ion generators as described in any one of claims 1-8; the controller is electrically connected to the semiconductor cooling chip, the discharge component, the boost component, and the acoustic vibration unit in the first generator module and the second generator module, respectively, for controlling the working state of the semiconductor cooling chip, adjusting the driving voltage of the discharge component, and controlling the brainwave intervention audio signal output by the acoustic vibration unit; the first generator module and the second generator module are respectively arranged near the user's left and right ears, and the controller is configured to output left channel audio signals and right channel audio signals to the acoustic vibration units of the first generator module and the second generator module, respectively. The brainwave intervention audio includes binaural isochronous pulse sounds and binaural difference frequency beat sounds; the controller is further configured to: in the initial working phase, control the acoustic vibration unit to output the binaural isochronous pulse sounds; after a preset time, control the acoustic vibration unit to gradually transition and output the binaural difference frequency beat sounds.

[0015] Furthermore, the VCC voltage signal output by the controller has a voltage value of 5V or 12V, and the VCC voltage signal is connected to the slow-wave hydration negative ion generator in any of the following ways: 1. The VCC voltage signal output by the controller is connected to the semiconductor cooling chip (3) through a resettable fuse and to the boost module (6) through another path. 2. The VCC voltage signal output by the controller is connected to the semiconductor cooling chip (3) through the overvoltage protection chip and to the boost module (6) through the other. 3. The VCC voltage signal output by the controller is divided into two paths after passing through a single-channel voltage detection chip. One path is connected to the semiconductor cooling chip (3) via the first MOS switch circuit, and the other path is connected to the boost module (6) via the second MOS switch circuit. The output terminal of the first MOS switch circuit is connected to the anode of the first diode, and the cathode of the first diode is connected to the input terminal of the boost module (6). The output terminal of the second MOS switch circuit is connected to the anode of the second diode, and the cathode of the second diode is connected to the input terminal of the semiconductor cooling chip (3). When the voltage value of the VCC voltage signal is 5V, the first MOS switch circuit is turned on, and when the voltage value of the VCC voltage signal is 12V, the second MOS switch circuit is turned on.

[0016] Furthermore, the controller is also connected to an audio source module, which contains audio files corresponding to 40Hz binaural isochronous pulse tone and binaural difference frequency beat tone; the controller includes a CPU, which is connected to the power amplifier via the IIS bus and transmits the audio files to the power amplifier. After processing the received audio files, the power amplifier outputs the left channel woofer signal and the right channel woofer signal to the low-frequency speaker (51).

[0017] The beneficial effects of this invention are as follows: This invention ingeniously combines an acoustic vibration unit, a semiconductor cooling chip, a discharge assembly, and a boost module. The acoustic vibration unit not only outputs brainwave intervention audio, but its vibration also serves as a power source, blowing out ions or ozone from the airflow channel. This eliminates the need for a separate fan structure, promptly removing ozone, making the device structure more compact, and improving device safety.

[0018] In the first working mode, a semiconductor cooling chip and a metal mesh plate are used to form a water film in a cooling state. The discharge needle tip discharges to the water film to generate hydrated negative ions, and the discharge carbon brush discharges to generate ordinary negative ions, achieving a high concentration and long-lasting negative ion release effect. In the second working mode, ozone is enriched by high-voltage discharge, and hot air is blown out by the acoustic vibration unit for sterilization, realizing the elimination of microorganisms inside and outside the generator.

[0019] By combining the sound wave intervention of binaural isochronous pulse tones and binaural difference frequency beat tones, along with the antioxidant effect of hydrated negative ions and the bactericidal effect of ozone, a multi-faceted protective pathway is formed, effectively improving the user's relaxation state, sleep quality, and safety.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0023] This invention provides a slow-wave hydration negative ion generator, comprising a housing with an open top and an internal cavity; a perforated metal plate disposed at the open top; a semiconductor cooling chip disposed within the cavity, the cooling or heating surface of which is thermally coupled to the perforated metal plate to form a condensate film on the surface of the metal plate or to heat the metal plate; a discharge assembly disposed within the cavity and opposite to the metal mesh plate, the discharge assembly being used for tip discharge under voltage drive; an acoustic vibration unit disposed on the side of the discharge assembly away from the metal mesh plate, the acoustic vibration unit being used to output brainwave intervention audio, and the vibration of the acoustic vibration unit driving the gas in the cavity to be discharged outwards; and a boost module disposed within the cavity, used to boost the input operating voltage to the voltage required for the discharge assembly to discharge.

[0024] This invention provides a slow-wave hydration negative ion generator that integrates audio brainwave intervention, negative ion / hydration negative ion maintenance, and ozone sterilization functions into one unit, achieving multiple working modes through a single hardware module. For example... Figure 1 , Figure 2 As shown, the generator includes a housing 1, a perforated metal plate 2, a semiconductor cooling chip 3, a discharge assembly 4, an acoustic vibration unit 5, and a boost module 6. Figure 3 , Figure 4As shown, the outer casing 1 is shaped like a handleless cup with an open top. Multiple second through holes 11 are provided at the bottom of the outer casing 1 to form airflow and audio output channels. An internal cavity and airflow channels are formed inside the outer casing 1. A wire avoidance hole is also provided at the bottom of the outer casing 1. The outer casing 1 is made of plastic, and multiple fixing posts 12 are provided along the side wall of the casing.

[0025] like Figure 1 As shown, a perforated metal plate 2 is disposed at the opening at the top of the outer casing 1, and is preferably made of stainless steel. Figure 5 As shown, the perforated metal plate 2 is preferably a porous disc structure. To optimize water film formation and airflow diffusion, the aperture of the openings in the central region of the porous disc structure is smaller, while the aperture of the openings in the outer region is larger. The smaller central openings allow for the accumulation of a larger water film on the lower surface of the perforated metal plate 2, facilitating the discharge of hydrated negative ions by the discharge needle tip. The larger outer openings facilitate the rapid outward diffusion of the generated ordinary negative ions and hydrated negative ions. Several through holes are provided on the perforated metal plate 2 for the fixing posts 12 to pass through. The top of the fixing posts 12 is slightly higher than the surface of the perforated metal plate 2. The fixing posts 12 are fixed to the through holes by heat fusion, thus fixing the perforated metal plate 12.

[0026] like Figure 6 , Figure 7 As shown, the thermoelectric cooler 3 is disposed below the perforated metal plate 2, with its cooling or heating surface thermally coupled to the perforated metal plate 2. According to the Peltier effect, the thermoelectric cooler 3 cools on one side and heats on the other when energized. In this embodiment, by controlling the current direction, the side of the thermoelectric cooler 3 facing the perforated metal plate 2 can be made to act as either a cooling or heating surface, or the current can be stopped, putting the thermoelectric cooler 3 in an off state. When acting as a cooling surface, moisture in the air can condense on the surface of the perforated metal plate 2 to form a condensate film; when acting as a heating surface, it can heat the perforated metal plate 2 and the air flowing through it. The thermoelectric cooler 3 needs to be used in conjunction with a heat dissipation device to minimize airflow between its cooling and heating surfaces to achieve the cooling or heating effect. Therefore, in this embodiment of the invention, the hydrated negative ion generator also includes a heat sink 7, which is thermally coupled to the lower surface of the thermoelectric cooler 3. When its lower surface is a heating surface, the heat sink 7 can conduct away the heat from the heating surface to improve the cooling effect of its upper surface. Conversely, the heat sink 7 can improve the heating effect of its upper surface. The heat sink 7 has a hollow structure, with its top end thermally coupled to the semiconductor cooling surface, and its size is designed according to actual needs. In some embodiments, the main body of the heat sink 7 is fitted over the discharge assembly 4 and the acoustic vibration unit 5; in other embodiments, the main body of the heat sink 7 is only fitted over the discharge assembly 4. The metal mesh plate 2 and the semiconductor cooling chip 3, as well as the semiconductor cooling chip 3 and the heat sink 7, are fixedly connected by thermally conductive silicone.

[0027] like Figures 6-10 As shown, the discharge assembly 4 is disposed within the housing cavity, below the semiconductor cooling chip 3, and opposite to the metal mesh plate 2. The discharge assembly 4 includes a discharge circuit board 41 and a circuit board support 42. The circuit board support 42 is a hollow structure with a thickness greater than that of the discharge circuit board 41. The discharge circuit board 41 is mounted on the top of the circuit board support 42. The acoustic vibration unit 5 is disposed below the bottom of the circuit board support 42, leaving a gap between the discharge circuit board 41 and the acoustic vibration unit 5 to prevent short circuits. The discharge circuit board 41 includes multiple discharge tips 411 and multiple discharge carbon brushes 412. The multiple discharge tips 411 are arranged in a ring array in a first region; the multiple discharge carbon brushes 412 are arranged in a ring array in a second region, which is located outside the first region. The discharge circuit board 41 is a printed circuit board, and its outer edge has multiple soldering areas 414 for connecting external controllers, external power supplies, and providing power transfer for the semiconductor cooling chip 3 and the acoustic vibration unit 5. Multiple first through holes 413 are provided on the inner side of the discharge circuit board 41 to form airflow channels. Specifically, the first through-hole 413 includes a central irregular-shaped hole and multiple strip-shaped holes surrounding it. Multiple discharge needle tips 411 and multiple discharge carbon brushes 412 are disposed between the irregular-shaped hole and the strip-shaped holes. Except for the areas necessary for the effective circuitry, a large number of first through-holes 413 can be provided. The multiple soldering areas 414 are manifested as multiple protrusions extending beyond the circuit board plane, with corresponding clearance positions provided on the circuit support 42. This invention does not impose special limitations on the number and position of the first through-holes 413. Preferably, multiple levels of locking positions can be provided in the hollow cavity of the circuit support 42, with each level of locking position having a different distance from the acoustic vibration unit 5. The discharge circuit board 41 can be connected to different locking positions via threads or snap-fit ​​connections to maintain different distances from the acoustic vibration unit 5.

[0028] like Figure 2 , Figure 6 As shown, the acoustic vibration unit 5 is located on the side of the discharge assembly 4 away from the metal mesh plate 2, specifically below the circuit board support 42. The acoustic vibration unit 5 outputs brainwave intervention audio, and the low-frequency mechanical vibrations it generates during sound emission also serve as an airflow power source, driving the gas within the containment cavity to be expelled. The vibration of the acoustic vibration unit 5 pushes the gas (carrying negative ions or ozone) in the airflow channel to be expelled, thus eliminating the need for a separate fan in traditional generators. Figures 11-13 As shown, the acoustic vibration unit 5 includes a low-frequency horn 51 and a horn resonant cavity 52. ​​The low-frequency horn 51 is disposed inside the horn resonant cavity 52, and an audio input wire is connected to the low-frequency horn 51. A wire avoidance hole is provided at the bottom of the horn resonant cavity 52.

[0029] like Figure 2 , Figure 6 , Figure 7 As shown, in this embodiment, the hydrated negative ion generator also includes a boost module 6, disposed within the receiving cavity, used to boost the input operating voltage to the voltage required for the discharge component 4 to discharge. Specifically, in some embodiments of the present invention, when the external input operating voltage is 12V, the output voltage is 3kV to 5kV; when the operating voltage is 5V, the output voltage is 1kV to 3kV.

[0030] The hydrated negative ion generator of this embodiment is configured as follows: In the first working mode, the semiconductor cooling chip 3 acts on the metal mesh plate 2 with its cooling surface to form a water film on the surface of the metal mesh plate 2; the discharge tip 411 discharges on the water film to generate hydrated negative ions; the discharge carbon brush 412 discharges to generate ordinary negative ions; In the second working mode, the semiconductor cooling chip 3 acts on the metal mesh plate 2 with its heating surface or remains in a closed state; the discharge tip 411 discharges on the metal mesh plate 2 to generate ozone.

[0031] Ozone generation requires a relatively high discharge voltage, while the generation of hydrated negative ions and ordinary negative ions requires a relatively low discharge voltage. When the external input operating voltage is 12V, the output voltage of the boost module 6 is 3kV to 5kV. At this time, if the thermoelectric cooler 3 is turned off or its upper surface is heated, the discharge tip 411 discharges, generating ozone with a high density. The acoustic vibration unit 5 blows out the ozone, achieving a sterilization effect. If the upper surface of the thermoelectric cooler 3 is switched to a cooling surface, a condensate film will gradually form on the metal mesh perforated plate 2. The discharge tip 411 discharges onto the water film to generate hydrated negative ions, and the discharge carbon brush 412 discharges to generate ordinary negative ions. When the external input operating voltage is 5V, the output voltage of the boost module 6 is 1kV to 3kV. Controlling the upper surface of the thermoelectric cooler 3 to switch to a cooling surface allows the discharge tip 411 and the discharge carbon brush 412 to generate hydrated negative ions and ordinary negative ions.

[0032] like Figure 14As shown, this embodiment of the invention also provides a health assistive device, including a controller, a first generator module, and a second generator module; the first and second generator modules are slow-wave hydrated negative ion generators as described above. The controller is electrically connected to the semiconductor cooling chip, discharge component, boost component, and acoustic vibration unit in the first and second generator modules, respectively, and is used to control the working state of the semiconductor cooling chip, adjust the driving voltage of the discharge component, and control the audio signal output by the acoustic vibration unit. The first and second generator modules are respectively arranged near the user's left and right ears. The controller is also connected to an audio source module, which contains audio files corresponding to 40Hz binaural isochronous impulse tones and binaural difference frequency beat tones. The controller is configured to output the left channel audio signal and right channel audio signal contained in the audio source module to the acoustic vibration units of the first and second generator modules, respectively. The health assistive device can specifically be a smart pillow or smart mattress or other sleep aids.

[0033] The controller's audio control logic is as follows: In the initial working phase (e.g., the first 3 minutes), the acoustic vibration unit outputs a 40Hz binaural isochronous pulse tone; after a preset time, it gradually transitions to output binaural difference-frequency beat tones to help the user gradually transition from a waking state to a relaxed, sleep-inducing state. The duration of the binaural difference-frequency beat tones is usually no less than 30 minutes. For the binaural isochronous pulse tone, the controller outputs audio with the same carrier frequency (e.g., 1kHz) to the left and right channels, and controls the on / off state at a frequency of 40Hz, i.e., 40 on / off cycles per second. The ears directly hear a clear 40Hz beat fluctuation, and the auditory cortex directly synchronizes with 40Hz gamma oscillations. This intervention helps improve the brain microenvironment. For the binaural difference-frequency beat tones, the controller outputs fixed intermediate frequency audio signals with specific frequency differences to the left and right channels, respectively. The frequency difference between the two is usually between 0.5Hz and 13Hz. The olivary nucleus on the brainstem calculates the frequency difference and virtually generates target brain waves, suitable for inducing relaxation and sleep regulation. The audio signal actually perceived by the user is as follows: Figure 15 As shown.

[0034] Figure 16 This is a circuit logic diagram for the controller and slow-wave hydration negative ion generator in a health-assisting device. (Example:) Figure 16As shown, the controller includes a CPU, which connects to the power amplifier via the IIS bus. The CPU transmits the digital audio signal corresponding to the audio file in the audio source module to the power amplifier. After processing the received digital audio signal, the power amplifier outputs the right channel woofer signal SPKL and the right channel woofer signal SPKR to the low-frequency speaker 51. Furthermore, the CPU connects to the control circuit via an I / O interface and inputs a VCC voltage signal to the control circuit. The control circuit outputs a VCC voltage signal to the boost converter circuit (i.e., boost module 6, discharge tip 411, and discharge brush 412). The boost module automatically identifies whether the input signal is 5V or 12V, and then outputs a discharge voltage of different values ​​after boosting. The discharge tip 411 and discharge brush 412 operate under the corresponding discharge voltage. Commercially available boost modules (commonly known in the industry as "boost converters") typically support 5-12V input voltages, such as TFB-YD552 and TFB-YD1252.

[0035] The control circuit also outputs a VCC voltage signal to the thermoelectric cooler 3. However, the thermoelectric cooler 3 cannot automatically recognize the voltage value of the input voltage signal, and therefore cannot switch its operating mode according to the voltage value. Therefore, a TEC mode control circuit is integrated on the discharge circuit board 41 to control the TEC operating mode of the thermoelectric cooler.

[0036] like Figure 17 This is a circuit block diagram of the TEC mode control circuit and boost module 6 in some embodiments of the present invention. The VCC voltage signal is divided into two paths: one path is connected to the thermoelectric cooler via a resettable fuse, and the other path is connected to the boost module 6. The holding current of the resettable fuse is 4A. When the VCC voltage signal is 5V, the current is less than 4A, the resettable fuse does not trip, maintaining a low-resistance state, the thermoelectric cooler 3 is normally energized, the upper surface is cooled, a water film is generated on the surface of the metal mesh plate 2, the discharge tip 411 and the discharge carbon brush 412 discharge, generating hydrated negative ions and ordinary negative ions, and the low-frequency horn vibrates, blowing out the hydrated negative ions and ordinary negative ions. When the VCC voltage signal is 12V, the current is greater than 4A, the resettable fuse trips, becoming a high-resistance state, the current in the thermoelectric cooler 3 drops to the mA level, almost not working, the discharge tip 411 discharges at high voltage, generating ozone, and the low-frequency horn vibrates, blowing out the ozone. Figure 17 The circuit design shown is simple, requiring only a resettable fuse and no control chips, switching transistors, etc., resulting in low cost and simple wiring. However, resettable fuses with a holding current of 4A or higher are expensive, and the fuse's activation delay can cause impacts on the downstream thermoelectric cooler 3, affecting its lifespan. Furthermore, the fuse's lifespan and stability are greatly affected by the environment, seriously impacting the overall reliability of the slow-wave negative ion generator.

[0037] like Figure 18This is a circuit block diagram of the TEC mode control circuit and boost module 6 in some other embodiments of the present invention. The VCC voltage signal is divided into two paths: one path is connected to the semiconductor cooling chip through the overvoltage protection chip, and the other path is connected to the boost module 6. The overvoltage protection chip has a specification of 5V / 4A. The overvoltage protection chip integrates a MOSFET to realize the function of 5V release and 12V shutdown. Specifically, when the voltage value of the VCC voltage signal is 5V, the input voltage is less than the overvoltage protection threshold of the overvoltage protection chip, the internal MOSFET is fully turned on, the semiconductor cooling chip 3 is normally powered, the upper surface is cooled, a water film is generated on the surface of the metal mesh plate 2, the discharge needle tip 411 and the discharge carbon brush 412 discharge, generating hydrated negative ions and ordinary negative ions, and the low-frequency speaker vibrates to blow out the hydrated negative ions and ordinary negative ions. When the VCC voltage signal is 12V, because the input voltage is greater than the overvoltage protection threshold of the overvoltage protection chip, the internal MOSFET is turned off, the semiconductor cooling chip 3 is de-energized, the discharge needle tip 411 discharges at high voltage, generating ozone, and the low-frequency horn vibrates to blow out the ozone. Figure 18 The solution shown is simple and easy to implement. Most overvoltage protection chips only require 1-2 capacitors, and some don't even need any external components. Furthermore, integrated overvoltage protection chips are less expensive. Compared to... Figure 17 In this solution, the overvoltage protection chip has a faster response time (typically in the ns~μs range), the input and output are completely isolated after the MOSFET is turned off, the leakage current is extremely low after turn-off, the electrical performance is stable, and the circuit reliability is higher.

[0038] like Figure 19 This is a circuit block diagram of the TEC mode control circuit and boost module 6 in some embodiments of the present invention. The VCC voltage signal, after passing through a single-channel voltage detection chip, is split into two paths: one path connects to the semiconductor cooling chip 3 via a first MOS switch circuit, and the other path connects to the boost module 6 via a second MOS switch circuit. The output terminal of the first MOS switch circuit is connected to the anode of the first diode, and the cathode of the first diode is connected to the input terminal of the boost module 6. The output terminal of the second MOS switch circuit is connected to the anode of the second diode, and the cathode of the second diode is connected to the input terminal of the semiconductor cooling chip. When the VCC voltage signal value is 5V, the first MOS switch circuit is turned on, the semiconductor cooling chip is energized, and its upper surface is cooled. The boost module 6 draws power through the first diode and the first MOS switch circuit, generating a water film on the surface of the metal mesh plate 2. The discharge needle tip 411 and the discharge carbon brush 412 discharge, generating hydrated negative ions and ordinary negative ions. A low-frequency speaker vibrates, blowing out the hydrated negative ions and ordinary negative ions. When the VCC voltage signal is 12V, the second MOS switch circuit is turned on, the boost module 6 is powered, the semiconductor cooling chip is powered through the second diode and the second MOS switch circuit, the upper surface is heated, the discharge tip 411 discharges at high voltage, generating ozone, and the low-frequency horn vibrates, blowing out the ozone and hot air. This solution is more efficient than... Figure 17 , Figure 18 The solution is more complex, with moderate overall cost, stable electrical performance, high lifespan and stability, and the semiconductor cooling chip 3 and boost module 6 can work simultaneously under different input voltages.

[0039] The above are merely specific embodiments of the present invention and should not be construed as limiting the scope of the present invention. Equivalent variations made by those skilled in the art based on this invention, as well as changes well-known to those skilled in the art, should still fall within the scope of the present invention.
