Description

Technical Field

[0001] This application belongs to the field of pet health care technology, specifically relating to a single-stage negative oxygen ion generator for pet health care, which is suitable for daily health care, sub-health conditioning, disease prevention and life extension care scenarios for domestic pets. Background Technology

[0002] With the large-scale and refined development of the pet breeding industry, pet health care has become a core necessity. In the field of pet health and wellness equipment, existing negative ion generators generally employ traditional dual-stage positive and negative ion co-generation technology, simultaneously producing positive and negative ions. Because collision discharge and arcing reactions easily occur when positive and negative ions coexist, ozone release during equipment operation often exceeds the national standard threshold of 0.1 mg / m³. Pets' respiratory systems and skin barriers are more fragile and sensitive than humans. Long-term exposure to excessive ozone can easily lead to respiratory mucosal inflammation, skin barrier damage, and oxidative stress, subsequently inducing various diseases such as skin and respiratory illnesses, ultimately harming the pet's health. Therefore, providing a negative ion generator that can reduce ozone concentration and is safe for pets has become a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0003] The purpose of this application is to provide a single-stage negative oxygen ion generator for pet health and wellness, which abandons the traditional two-stage ion generation principle and realizes pure negative ion unidirectional output.

The single-stage negative oxygen ion generating module includes a high-voltage capacitor coupling circuit and an emitter unit. The output terminal of the high-voltage capacitor coupling circuit is only connected to the negative polarity emitter and no positive high-voltage electrode or positive ion emitter is provided, so that the device generates only negative ions and no positive ions during operation. An ultra-fine particle size control module is located on the emission path of the emitter unit to homogenize and guide the generated negative oxygen ions; The main control module, located inside the housing, is electrically connected to the power module, the single-stage negative oxygen ion generation module, and the ultra-fine particle size control module. It is used to output control commands to each module to achieve the overall coordinated operation of the device.

[0006] Optionally, the high-voltage capacitor coupling circuit operates at a frequency of 20kHz to 80kHz and has an output voltage of -5kV to -30kV; the emitter unit consists of 9 to 96 emitter needles arranged in a ring or matrix, and the tip curvature radius of the emitter needles is 0.05 to 0.3mm.

[0007] Optionally, the ultra-fine particle size control module is a porous honeycomb structure device made of high dielectric constant piezoelectric ceramic material, wherein the honeycomb pore size is 0.5 to 2 mm and the thickness is 3 to 10 mm.

[0008] Optionally, it also includes a high-concentration regulated output module, which includes a voltage feedback adjustment circuit for sampling the output voltage of the high-voltage capacitor coupling circuit in real time and automatically adjusting the PWM duty cycle through a PID algorithm to stabilize the output of negative high voltage, so that the ion release concentration is maintained within a preset range.

[0009] Optionally, it also includes a low ozone purification matching module, which includes an ozone concentration sensor and a microcontroller; the ozone concentration sensor is located inside the ion release window and is used to monitor the ozone concentration at the release port in real time; the microcontroller has a preset ozone safety threshold, and when the monitored value reaches or exceeds the safety threshold, the microcontroller sends a trigger signal to the main control module to reduce the high voltage output or cut off the power supply.

[0010] Optionally, the ozone safety threshold is not higher than 0.003 mg / m³; the microcontroller is also connected to a temperature sensor, which automatically performs overheat protection when the temperature exceeds 70°C.

[0011] Optionally, the housing is equipped with a tilt power-off protection device that automatically cuts off the power supply when the housing tilts at an angle ≥45°; the edge of the ion release window on the outside of the housing is designed with rounded corners and a chamfer radius ≥2mm.

[0013] Optionally, the power cord is fitted with an anti-bite braided sleeve, and the connection between the power cord and the housing is fitted with a tensile sheath with a tensile strength ≥50N; the air inlet is fitted with a removable dust filter.

[0015] Compared with the prior art, this application has the following beneficial effects: This application employs a single-stage negative high-voltage power supply scheme. The output terminal of the high-voltage capacitor coupling circuit is only connected to the negative polarity emitter, without setting a positive high-voltage electrode or a positive ion emitter. This ensures that the device generates only negative ions and not positive ions during operation, thereby avoiding the conditions for positive and negative ion collision discharge, arc reaction, and secondary oxidation reaction. This avoids the core cause of ozone generation and solves the technical problem of continuous ozone exceedance caused by the coexistence of positive and negative ions in traditional two-stage equipment. The device does not cause irritation or damage to the pet's respiratory tract and skin during long-term operation, significantly improving the safety of pet health and wellness equipment.

[0016] In addition, this application sets an ultra-fine particle size control module in the emission path of the emitter unit to homogenize the nascent negative oxygen ions, eliminate the problem of uneven ion particle size distribution, and guide the ion flow, so that the negative ions diffuse evenly towards the release port, reducing the loss and recombination of ions near the release port, improving the effective output rate of negative ions, and creating favorable conditions for negative ions to exert their biological activity. Attached Figure Description

[0017] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Furthermore, these drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments.

[0018] Figure 1 This is a schematic diagram of the module electrical connection of a single-stage negative oxygen ion generator for pet health care, provided in an embodiment of this application. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] Example 1 like Figure 1 As shown in the figure, this embodiment provides a single-stage negative oxygen ion generator for pet health and wellness, which includes a shell, a power module, a single-stage negative oxygen ion generation module, an ultra-fine particle size control module, and a main control module. The specific structure, implementation details, operating parameters, and core functions of each module are described below.

[0021] The housing protects other modules. The main body of the housing can be made of ABS flame-retardant engineering plastic (UL94 V-0 grade), and the interior features modular mounting cavities. The front of the housing has an ion release window (grid or mesh structure, opening ratio ≥60%), and the back or bottom has an air inlet (grid structure, opening ratio ≥50%) to ensure ion release efficiency. The edges of the external ion release window are rounded (bevel radius ≥2mm) to prevent scratching pets. The bottom of the device has anti-slip feet (silicone material, 3~5mm thick) to ensure stability.

[0022] It is understandable that the main body of the shell can also be made of metal to enhance the shielding effect and structural strength.

[0023] The power module is located inside the housing and is used to convert external AC power into low DC voltage and further boost it to the operating voltage.

[0024] Specifically, the power supply module includes an AC-DC conversion module (converting 220V / 110V AC power to 12V or 24V DC low voltage with a conversion efficiency ≥85%) and a DC-DC boost module (boosting the 12V / 24V to the 300V~500V operating voltage required by the high-voltage module). The power supply module is electrically connected to the high-voltage capacitor coupling circuit of the single-stage negative oxygen ion generating module. The power input terminal is equipped with an overcurrent protection module (rated current 2A) and an electromagnetic compatibility filter (to suppress high-frequency conducted interference).

[0025] A single-stage negative oxygen ion generating module is disposed inside the housing and electrically connected to the power module to generate a pure negative oxygen ion stream. The single-stage negative oxygen ion generating module includes a high-voltage capacitive coupling circuit and an emitter unit. The output terminal of the high-voltage capacitive coupling circuit is only connected to the negative polarity emitter; no positive high-voltage electrode or positive ion emitter is provided, so that the device generates only negative ions and not positive ions during operation.

[0026] The specific implementation details of the single-stage negative oxygen ion generation module are as follows: (1) High-voltage capacitor coupling circuit: includes a high-frequency high-voltage transformer (operating frequency 20kHz~80kHz), a multi-stage voltage multiplier rectifier circuit (2~6 stages of voltage multiplication), a current-limiting protection resistor (resistance value 10MΩ~100MΩ), and a high-voltage ceramic capacitor (withstand voltage ≥40kV, capacitance value 100pF~1000pF). The specific circuit configuration is as follows: the high-frequency high-voltage transformer inputs a 12V / 24V DC voltage and generates a high-frequency high-voltage signal through an oscillation circuit; the multi-stage voltage multiplier rectifier circuit performs multi-stage voltage multiplication rectification on the AC high voltage output from the high-frequency high-voltage transformer to convert it into a stable DC negative high voltage; the current-limiting protection resistor is connected in series in the high-voltage output circuit to limit the discharge current within a safe range (≤1mA) to prevent overcurrent damage to the equipment and abnormal discharge.

[0027] (2) Emitter Unit: Consists of 9 to 96 emitting pins arranged in a ring or matrix. The emitting pins are made of nano-carbon fiber or platinum alloy-coated tungsten wire, with a tip curvature radius of 0.05 to 0.3 mm. Each emitting pin is welded to a copper conductive substrate, which is connected to the output terminal of a capacitive coupling circuit via a high-voltage wire. A polytetrafluoroethylene (PTFE) insulating support is provided around the emitter unit to ensure a safe electrical distance (≥15 mm) between the emitting pins and the housing and other metal parts.

[0028] Thus, the generation of positive ions can be avoided by using a single-stage negative high-voltage scheme, eliminating the core cause of ozone generation; the multi-emission needle array generates a multi-point corona superposition effect, and the ion generation density per unit space increases exponentially.

[0029] It is understandable that the emitter can be replaced by a discharge brush structure; the emitter material can be a platinum alloy-plated tungsten wire or a pure tungsten wire.

[0030] The ultra-fine particle size control module is located on the emission path of the emitter unit and is used to homogenize and guide the generated negative oxygen ions.

[0031] Specifically, the ultra-fine particle size control module is a porous honeycomb structure device made of high dielectric constant piezoelectric ceramic material (lead zirconate titanate PZT ceramic, dielectric constant εr≥1000), with a honeycomb pore size of 0.5 to 2 mm and a thickness of 3 to 10 mm. When the nascent negative ions pass through the microporous channels of the porous honeycomb structure device, they are filtered and polarized by the electric field of the inner wall of the channel. Large-diameter ion clusters are adsorbed and deposited on the inner wall of the channel, while small-diameter ions pass through smoothly, achieving secondary particle size homogenization and ensuring that the produced ions are small-diameter particles, giving the negative ions extreme biological permeability. At the same time, the honeycomb through-hole microporous structure guides the ion flow, causing the ions to diffuse uniformly towards the release port, reducing ion loss and recombination near the release port.

[0032] The main control module is located inside the housing and is electrically connected to the power module, the single-stage negative oxygen ion generation module, and the ultra-fine particle size control module. It is used to output control commands to each module to achieve the overall coordinated operation of the device.

[0033] The main control chip for the main control module can be a domestically produced low-power microcontroller (such as the HC32F030 series), with a standby current of <0.8μA, a main operating frequency of 48MHz, and support for multi-channel ADC acquisition, PWM output, and various communication interfaces. It features low power consumption and high reliability, making it suitable for the long-term continuous operation requirements of pet healthcare equipment. Alternatively, the STM32F103C8T6 microcontroller can be used, with a standby current of <1μA, an operating speed of 72MHz, and support for multi-channel data acquisition and precise PWM output.

[0034] In addition, a single-stage negative oxygen ion generator for pet health and wellness may also include a high-concentration stable voltage output module.

[0035] The high-concentration regulated output module includes a voltage feedback adjustment circuit, which is used to sample the output voltage of the high-voltage capacitor coupling circuit in real time, and automatically adjust the PWM duty cycle through a PID algorithm to stabilize the output of negative high voltage, so that the ion release concentration is maintained within a preset range.

[0036] Specifically, the voltage at the output of the high-voltage capacitor coupling circuit is sampled in real time through a high-voltage side voltage divider resistor network (voltage division ratio 1000:1). The sampled signal is then sent to the ADC input of the microcontroller after being isolated by an isolation amplifier. When the voltage fluctuation exceeds the set threshold (±5%), the microcontroller automatically adjusts the PWM duty cycle of the drive signal through a PID algorithm to stabilize the output of negative high voltage, thereby maintaining a constant ion release concentration.

[0037] In this way, the voltage closed-loop feedback ensures that the ion release concentration does not fluctuate with power grid fluctuations or environmental changes, thus guaranteeing the stability and consistency of the maintenance effect.

[0038] In addition, the single-stage negative oxygen ion generator for pet health and wellness may also include a low ozone purification matching module.

[0039] The low-ozone purification matching module includes an ozone concentration sensor and a microcontroller. The ozone concentration sensor is located inside the ion release window and is used to monitor the ozone concentration at the release port in real time. The microcontroller has a preset ozone safety threshold. When the monitored value reaches or exceeds the safety threshold, the microcontroller sends a trigger signal to the main control module to reduce the high-voltage output or cut off the power supply.

[0040] In practice, the low-ozone purification matching module incorporates an electrochemical ozone concentration sensor (detection range 0~0.5mg / m³, resolution 0.001mg / m³, response time ≤30 seconds), installed on the side wall of the ion release channel (e.g., 20mm inside the release port). This sensor collects ozone concentration data near the release port in real time, which is then transmitted to the microcontroller for processing. The microcontroller has a preset safety threshold of no more than 0.003mg / m³. When the monitored value reaches or exceeds this threshold, the microcontroller executes a protection action within 1 second, sending a trigger signal to the main control module to reduce the high-voltage output to the lowest level via PWM. If the ozone concentration still exceeds the limit after 3 seconds, the high-voltage power supply is completely cut off. Intermittent alarm sounds are also emitted via audible and visual alarms (such as indicator lights and buzzers).

[0041] The microcontroller can also be connected to a temperature sensor, which automatically performs overheat protection when the temperature exceeds 70°C (adjustable). The temperature sensor is an NTC thermistor (resistance 10kΩ@25°C, B value 3435K), mounted on the surface of the high-voltage module's heatsink. When the temperature exceeds 70°C, the microcontroller sends a trigger signal to the main control module, causing the main control module to automatically reduce the high-voltage output power (to 50% of the current level); when the temperature exceeds 80°C, the main control module immediately cuts off the power supply.

[0042] In addition, the single-stage negative oxygen ion generator for pet health and wellness can also include a safety protection module.

[0043] The safety protection module includes a tilt power-off protection device installed on the housing, which automatically cuts off the power when the housing tilts at an angle ≥45°; the edges of the ion release window on the outside of the housing are designed with rounded corners and a chamfer radius ≥2mm.

[0044] The specific implementation details of the security protection module are as follows: (1) Tilting power-off protection: A ball-type tilt sensor (operating angle 45°±5°) is installed at the bottom of the housing. When the tilt angle of the equipment is ≥45°, the ball inside the sensor triggers the switch to open. After the microcontroller detects the signal change, it cuts off the high-voltage power supply within 0.5 seconds. After the equipment returns to its normal placement position, it needs to be manually restarted.

[0045] (2) Rounded corner design: The edges of the ion release window on the outside of the shell are rounded with a chamfer radius of ≥2mm to prevent pets from scratching.

[0046] (3) Anti-bite design: The power cord is fitted with an anti-bite braided sleeve, and the connection between the power cord and the housing is fitted with a tensile sheath with a tensile strength ≥50N. The anti-bite braided sleeve is made of nylon 66 with a wear resistance rating of ≥1000 abrasions; the tensile sheath is an SR type rubber sheath, and the power cord is 1.8 meters long after exiting the housing.

[0047] (4) Air inlet protection: The air inlet is equipped with a detachable dust filter (nylon mesh, mesh number ≥60 mesh) to prevent pet hair and dander from being sucked into the equipment.

[0048] Thus, through multiple pet-specific safety designs, the safety of pets and equipment is comprehensively protected, adapting to the special needs of pet activity scenarios.

[0049] In addition, a control panel is located on the outside of the casing. The control panel includes multi-level concentration adjustment buttons, with at least low, medium, and high levels. Different levels correspond to different output negative high voltages and ion release concentrations.

[0050] Specifically, the control panel is located on the surface of the housing or operated via remote control, and includes: Power switch: Specifically, it can be a touch-sensitive switch, and may include an indicator light; Multi-level concentration adjustment buttons, such as low / medium / high; The timer button can be set to run for 2 hours, 4 hours, 6 hours, 8 hours, or continuously. The operating status indicator light shows a solid green light for normal operation, a flashing yellow light for concentration adjustment, and a solid red light for a fault / protection status. A digital tube or LCD display screen (optional) is used to display information such as the operating gear and remaining time in real time.

[0051] The three concentration levels are adjusted as follows: Low setting (Level I): Outputs negative high voltage of approximately -8kV, ion concentration of 2~500 million / cm³, suitable for young pets (<6 months old), senior pets (>10 years old), and the initial adaptation period. Recommended usage time is 4~6 hours / day.

[0052] Medium range (Level II): Output negative high voltage of about -15kV, ion concentration of 50~15 billion / cm³, suitable for daily health care and sub-health conditioning of adult pets (1~8 years old), recommended usage time is 6~8 hours / day.

[0053] High-end (Level III): Outputs negative high voltage of approximately -25kV, with an ion concentration of 300~600 billion / cm³. Suitable for those who are weak, recovering from illness, post-operatively, or undergoing intensive conditioning for the elderly. Recommended usage time is 4~6 hours / day (can be divided into 2~3 sessions).

[0054] In this way, multiple adjustable settings can be used to adapt to the different needs of different pet breeds, ages, and physical conditions, thus realizing a personalized care plan for each pet.

[0055] It is understandable that, in practical implementation, a knob-type adjustment can be used instead of a button-type adjustment; intelligent sensing can be added to automatically adjust the gear.

[0056] To achieve overall control of the device, the main control module incorporates a built-in control algorithm: a piecewise linear gradient voltage regulation algorithm. Based on the user-selected speed (low / medium / high), it outputs a corresponding PWM duty cycle signal to the high-voltage capacitor coupling circuit to adjust the high-voltage output value. Simultaneously, the main control module receives real-time monitoring data from the ozone sensor. When the ozone concentration approaches a preset safety threshold, it automatically executes a three-level buffer control strategy: first, reduce the fan speed; then, lower the high voltage; finally, trigger an over-limit shutdown alarm. The main control module also receives signals from the temperature sensor; when the temperature exceeds 60℃, it automatically reduces the output power, and when it exceeds 70℃, it immediately cuts off the high-voltage power supply.

[0057] In addition, the main control module is electrically connected to the power module, the control terminal of the high-voltage capacitor coupling circuit, the ozone sensor, the temperature sensor, the tilt detection switch, the buttons and display screen of the control panel, the buzzer, and the indicator lights via ribbon cables or wires. Specifically, the PWM output terminal of the main control module is connected to the drive input terminal of the high-voltage capacitor coupling circuit for adjusting the high-voltage output; the ADC input terminal is connected to the analog output terminal of the ozone sensor and the voltage divider output terminal of the temperature sensor for collecting environmental parameters; the GPIO input terminal is connected to the tilt detection switch and button signals; and the GPIO output terminal is connected to the driver circuits of the buzzer, indicator lights, and display screen.

[0058] In addition, the main control module has a built-in timer, and users can set the running time (2h / 4h / 6h / 8h / continuous operation) through the timer button on the control panel. After the set time is reached, the main control module will automatically cut off the high voltage output and control the buzzer to sound a short alarm.

[0059] This device is easy to operate, requiring no professional skills and no grounding accessories for the pet. It is available in two scenarios: tabletop use and cage-mounted use. Both scenarios follow a core process of "device placement → parameter setting → power-on → operation termination," as detailed below: 1. Tabletop placement (suitable for indoor free-roaming pets) Device Placement: Place the device in a stable, well-ventilated location on the side of the pet's daily activity area, 0.8-2m away from the pet's resting spot, and keep an appropriate distance (≥0.5m) from the water and food bowls to avoid moisture ingress; the non-slip pads on the bottom of the device can ensure stable placement, and at the same time, ensure that the ion release window faces the direction of the pet's activity.

[0060] Parameter Settings: Connect to a 12V power supply and turn on using the power button on the control panel. Select the appropriate setting based on your pet's breed, age, and physical condition—low setting is recommended for puppies (<6 months old), senior pets (>10 years old), or first-time users; medium setting for daily care of healthy adult pets; and high setting for weak pets, post-operative recovery, or intensive care for older pets. Set the duration of each session using the timer button (it is recommended to start with a short duration for first-time users and gradually increase the time as they adapt).

[0061] Powering on: Press the start button to begin operation. The indicator light will show green when the device is running normally. During operation, negative ions naturally diffuse into the pet's activity area through the ion release window. Pets do not need to approach; the negative ions can actively penetrate the pet's microcirculation through skin capillaries, reaching the blood, cells, and core organs. This continuously neutralizes harmful positive ions and free radicals in the body, purifies the internal environment, activates cell activity, accelerates metabolic circulation, inhibits inflammation, and slows cell aging. During use, ensure adequate ventilation in the room and prevent pets from chewing on the device's air vents and power cord.

[0062] End of operation: The device will automatically shut down after the set time (short beep to indicate this); if you wish to end the operation early, you can manually press the power button to turn it off. Wait 2 minutes (for any residual charge inside the device to dissipate naturally) before disconnecting the power or moving the device.

[0063] 2. Cage hanging type (suitable for caged pets) Equipment mounting: Fix the matching hooks to the top or side of the pet cage. The equipment should be hung at least 10cm above the pet's maximum standing height to prevent the pet from chewing on the air outlet and high-voltage components.

[0064] Parameter settings and operation: Refer to the parameter settings for the desktop version and select the corresponding setting according to the pet type. The device's 120° wide airflow naturally fills the cage space through the ion release window, continuously balancing the ion concentration inside the cage. Relying on the spatial ion concentration gradient, negative ions naturally penetrate the pet's skin.

[0065] Usage duration: For caged sick pets and young pets, the low setting should be used first to avoid long-term close-range stimulation of high concentration. The recommended duration is 15-30 minutes per session. For healthy adult pets, the medium setting can be used, with a duration of 20-40 minutes per session. For elderly pets, the high setting is recommended and should be used in conjunction with timed cyclical intermittent operation (stop for 5 minutes to cool down after every 30 minutes of operation).
