Description

Technical Field

[0001] This utility model relates to the technical field of negative oxygen devices, specifically to a micro-pressure negative oxygen generator. Background Technology

[0002] Negative oxygen ions are negatively charged oxygen molecules, often referred to as "air vitamins." Forests and areas near waterfalls have high concentrations of negative oxygen ions. Inhaling these ions is beneficial to health, improving cardiopulmonary function and refreshing the mind. They can enter the body through respiration or skin contact, improving respiratory function, regulating the nervous system, enhancing immunity, and positively impacting the cardiovascular and metabolic systems. They can also increase the number of white blood cells in the blood, enhancing the body's antiviral capabilities.

[0003] However, existing negative ion devices have low integration, are bulky, and cannot achieve air purification effects, with relatively limited functionality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a micro-pressure negative oxygen generator to solve the problems of low integration, large size, inability to achieve air purification effect, and relatively simple function of existing negative oxygen generators.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0043] Example 1

[0044] Figure 1 This is a schematic diagram of the overall structure of a micro-pressure negative oxygen generator according to an exemplary embodiment. The device includes:

[0045] The housing includes an upper outer shell 6 and a lower outer shell 12;

[0046] A PCB circuit board 11 is provided inside the housing;

[0047] The PCB circuit board 11 is equipped with a miniature air compressor 1, a negative oxygen generator 2, and an air filter 3.

[0048] The negative oxygen generator 2 is connected to the air inlet of the micro air compressor 1 through an air intake pipe, and the air outlet of the micro air compressor 1 is connected to the air outlet pipe 7.

[0049] The air filter 3 is used to filter the incoming air;

[0050] The negative oxygen generator 2 is used to generate air with negative oxygen ions based on the filtered air and negative high pressure.

[0051] The miniature air compressor 1 is used to draw the generated air containing negative oxygen ions into itself through the intake pipe and discharge it through the exhaust pipe 7.

[0052] As attached Figure 2 As shown,

[0053] The PCB circuit board 11 is also provided with a flow regulation module 8, which is used to control the input voltage of the micro air compressor 1 to regulate the power of the micro air compressor, thereby controlling the flow rate of inhaled and exhaled negative oxygen ions.

[0054] The PCB circuit board is also equipped with a lithium battery 5 and a pulse control module 4;

[0055] The lithium battery 5 is used to power the electronic components on the PCB circuit board 11;

[0056] The pulse control module 4 is used to generate a negative high voltage according to the voltage output by the lithium battery 5 and supply it to the negative oxygen generator 2. The negative oxygen generator 2 generates negative oxygen ions according to the negative high voltage.

[0057] The PCB circuit board 11 is also provided with a USB charging port 9 and a battery charging inverter circuit.

[0058] The USB charging port 9 is connected to an external charging power source, and the lithium battery 5 is charged through the battery charging inverter circuit.

[0059] The PCB circuit board 11 is also provided with a start / stop switch 10, which is used to control the on / off of the power supply line of the lithium battery 5.

[0060] Appendix Figure 3 This is the overall circuit schematic diagram of this embodiment, wherein the amplification section of the battery charging inverter circuit is shown in the attached diagram. Figure 4 As shown,

[0061] The battery charging inverter circuit uses an ETA9740 input / output port chip. Pins A12 and A5 of the USB charging port (+5V) are connected to pin 7 of the ETA9740 input / output port. Capacitors C4 and C7 are used to filter out interference. Pin 1 of the ETA9740 chip outputs a square wave, which charges the lithium battery 5 through inductor L1. After charging is complete, LEDs 1-4 are the power and charging indicator lights. R5 and R6 are LED current-limiting resistors, and R7 is the charging current setting resistor. Changing the resistance of R7 changes the charging current. The inverter boosts the voltage to 3.7V, which is connected to inductor L1 and pin 6 of the ETA9740 chip to form the inverter circuit. Pin 7 of the ETA9740 chip outputs 5V to supply the pulse control module 4 and the flow regulation module 8. Since the current inversion is a static current and the current is very small, no switch is designed.

[0062] The amplification section of flow regulation module 8 is shown in the attached figure. Figure 5As shown, the circuit uses an MT2492 chip, whose maximum input voltage is 4.5-16V. In this embodiment, a 5V input power supply is used, and the output voltage of 2.5-4.8V is provided to the miniature air compressor 1. When working, the on / off switch 10 is turned on, and pins 4 and 5 of the MT2492 chip are powered on. The internal oscillation circuit starts to work, and the upper and lower MOSFETs at the output end conduct alternately to charge capacitors C19 and C13 through inductor L2. Resistor R13 is a voltage feedback resistor. Resistor R12 and potentiometer form a feedback adjustment circuit. By adjusting the potentiometer, the voltage of the FB pin of the MT2492 chip is changed, thereby changing the output pulse width of the chip, and thus changing the voltage across capacitors C19 and C13, adjusting the flow rate of the miniature air compressor 1 from the range of 2.5-4.8V. The MT2492 chip features the following characteristics: up to 96% conversion efficiency; switching frequency: high-frequency operation at 600kHz; output current: supports up to 2A output current; input voltage range: wide input voltage range from 4.5V to 16V; no Schottky diode required: integrated synchronous rectification; reference voltage: stable reference voltage of 0.6V; control method: slope-compensated current mode control, providing excellent line and load transient response; output capacitor stability: compatible with low ESR ceramic output capacitors; protection functions: overcurrent protection and hiccup mode, thermal shutdown protection; soft-start function: built-in soft-start function to prevent output voltage overshoot during startup; package: SOT23-6 package, RoHS compliant; operating temperature range: -40℃ to +85℃.

[0063] The amplification section of pulse control module 4 is shown in the attached figure. Figure 6 As shown, the NE555 chip, resistors R8 and R9, and capacitor C10 form an astable multivibrator to generate a rectangular wave pulse signal. Diode D2 and resistor R25 form a pulse width modulation circuit to adjust the pulse width of the rectangular wave pulse signal. The output pulse from pin 3 of the NE555 is fed to the gate of MOSFET Q1 through capacitor C15 and resistor R10. When MOSFET Q1 is turned on, the primary coil of the high-voltage transformer is energized, generating a magnetic field. This field induces a voltage through the secondary winding of the magnetic core, which is then rectified by a voltage multiplier circuit consisting of capacitors C22 and C23, diode D4, and diode D5 to form a negative high voltage, which generates negative oxygen ions for negative oxygen generator head 2.
