Description

Technical Field

[0001] This invention relates to the field of high-altitude protective respiratory equipment technology, specifically a high-altitude adaptive high-altitude pressurized negative ion oxygen supply mask. Background Technology

[0002] High-altitude regions are characterized by high elevation, low atmospheric pressure, and thin air, with the partial pressure of oxygen per unit volume of air being much lower than in plains areas. When people enter high-altitude environments, they are highly susceptible to hypoxia due to insufficient oxygen intake, leading to altitude sickness symptoms such as headaches, dizziness, chest tightness, shortness of breath, and weakness in the limbs. In severe cases, this can impair health and normal mobility.

[0003] Currently available traditional high-altitude protective masks only have basic functions such as windproofing, dustproofing, warmth preservation, and simple filtration of impurities. They cannot pressurize or improve the quality of the inhaled thin air, cannot increase the oxygen partial pressure of the inhaled air, cannot fundamentally improve the problem of high-altitude hypoxia, and have extremely poor effects in relieving altitude sickness.

[0004] The following technical problems exist with a small number of existing electrically powered respirators: Firstly, it lacks altitude adaptive adjustment function and mostly operates at a fixed speed. At low altitudes, it consumes too much energy and has a short battery life. At high altitudes, when oxygen deficiency is severe, the oxygen supply is insufficient, resulting in poor adaptability. Secondly, the airflow design is unreasonable, with no independent channels for inhalation and exhalation. Carbon dioxide exhaled by the human body easily accumulates inside the mask cavity, causing secondary inhalation of waste gas and exacerbating the body's discomfort due to lack of oxygen.

[0005] Third, existing equipment, relying solely on filtration or simple air supply, cannot effectively improve the body's blood oxygen utilization rate, and its effect on alleviating altitude sickness is limited.

[0006] Given the shortcomings of existing technologies, there is an urgent need to develop a high-altitude-specific respirator that is structurally sound, scientifically designed, adaptable to different altitudes, and allows for independent exhaust of waste gas. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide an altitude-adaptive, high-altitude pressurized negative ion oxygen supply mask. This mask aims to increase the partial pressure of oxygen in inhaled air through mechanical pressurization, optimize the body's oxygen utilization efficiency with negative oxygen ions, and simultaneously achieve automatic adaptation to different altitude conditions and independent directional exhaust of exhaled waste gas. This scientifically and effectively alleviates altitude sickness symptoms and improves wearing comfort and safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An altitude-adaptive plateau pressurized negative ion oxygen supply mask includes a mask body and a breathing cavity disposed inside the mask body for fitting the mouth and nose area of ​​the human body. The mask body integrates a pressurized air intake module, an altitude-adaptive control module, and an exhaust gas exhaust module. The booster air intake module includes a micro turbine fan, a booster airflow channel, and a negative oxygen ion generator. The air intake end of the micro turbine fan is connected to the outside atmosphere, and the air outlet end is connected to the input end of the booster airflow channel. The negative oxygen ion generator is disposed in the booster airflow channel and is used to ionize the air in the booster airflow channel to generate negative oxygen ions. The output end of the booster airflow channel is connected to the breathing cavity. The altitude adaptive control module includes an altitude detection unit and a main control circuit board. The altitude detection unit is used to collect environmental altitude data and transmit it to the main control circuit board. The main control circuit board is electrically connected to the micro turbine fan and the negative oxygen ion generator, respectively, and is used to adjust the speed of the micro turbine fan and the output power of the negative oxygen ion generator according to the altitude data. The exhaust gas module includes an exhalation exhaust channel and a one-way exhaust valve. One end of the exhalation exhaust channel is connected to the breathing cavity, and the other end extends to the outside of the mask body. The one-way exhaust valve is located at the exhaust port of the exhalation exhaust channel. The exhalation exhaust channel and the pressurized airflow channel are independent of each other and are not connected.

[0009] Furthermore, the mask body also integrates a voice amplification module, which includes a miniature microphone and an external miniature speaker. The miniature microphone is positioned within the breathing cavity near the oral cavity, while the external miniature speaker is embedded in the side wall of the mask body. Both the miniature microphone and the external miniature speaker are connected to a main control circuit board, which integrates an audio signal processing circuit. The input of the audio signal processing circuit is connected to the miniature microphone, and the output is connected to the external miniature speaker. The miniature microphone collects the wearer's voice sound wave signal, which is then processed by the main control circuit board for noise reduction and signal amplification before driving the external miniature speaker to emit sound. This counteracts the sound wave attenuation caused by the mask structure, improving the volume and clarity of the wearer's communication.

[0010] Furthermore, the main control circuit board is configured to output a corresponding drive signal based on the altitude data collected by the altitude detection unit. As the altitude increases, the drive signal synchronously increases the rotational speed of the micro turbine fan and the output power of the negative oxygen ion generator.

[0011] Furthermore, the one-way exhaust valve is a silicone one-way check valve, and its conduction direction is set to allow gas to be discharged from the inside of the breathing cavity to the outside, while blocking external gas from entering the breathing cavity in the reverse direction from the exhalation exhaust channel.

[0012] Furthermore, an insulating layer is provided inside the interlayer of the main body of the mask. The micro turbine fan, the negative oxygen ion generator, and the main control circuit board are all located on the side of the insulating layer away from the human face, and are completely isolated from the breathing cavity and the human face area.

[0013] Furthermore, the micro turbine fan, the negative oxygen ion generator, and the main control circuit board are all embedded thin structures, which are housed within the interlayer space of the mask body and do not protrude from the outer surface of the mask body.

[0014] Furthermore, the edges of the mask body adopt an elastic sealing structure to conform to the contours of the human face in order to maintain the airtightness of the breathing cavity.

[0015] In summary, the present invention has the following advantages: 1. Dual scientific enhancement for efficient relief of altitude sickness: It adopts a dual synergistic mechanism of mechanical pressurization to increase the partial pressure of oxygen in the intake air and negative oxygen ions to optimize blood oxygen utilization efficiency. It improves the problem of hypoxia at high altitude from both the air source and the human body absorption end. The principle is scientifically rigorous and can effectively improve blood oxygen saturation and significantly relieve symptoms of altitude sickness such as dizziness, chest tightness, and shortness of breath.

[0016] 2. Intelligent Adaptive Control at All Altitudes: Equipped with an altitude detection unit and a main control circuit board, the adaptive control system automatically matches the fan pressurization intensity and negative oxygen ion generation at different altitudes through a hardware gating structure. It takes into account both the energy-saving and long-lasting needs at low altitudes and the strong oxygen supply at high altitudes, making it suitable for a wide range of scenarios and eliminating the need for manual adjustment.

[0017] 3. Dual independent ventilation for clean and comfortable breathing: The independent dual-channel design for air intake and exhaust, combined with a one-way check-back exhaust structure, enables the directional discharge of exhaust gas and effectively isolates it from external impurities, eliminating the problems of exhaust gas retention and secondary inhalation. It also results in low breathing resistance and excellent wearing comfort.

[0018] 4. Safe and durable structure: All electrical components are embedded and hidden, lightweight and burden-free to wear; electrical components are completely isolated from the human body, making them safe and reliable to use; specific usage scenarios are defined to effectively avoid equipment failure and extend service life.

[0019] 5. Excellent airtightness and stable pressurization effect: The elastic sealing structure of the mask edge fits the contour of the face, ensuring the airtightness of the breathing cavity, preventing the leakage of pressurized gas, and ensuring the stable operation of each module.

Detailed Implementation

[0022] The present invention will now be described in further detail.

[0023] like Figure 1 and Figure 2 As shown, this invention discloses an altitude-adaptive, high-altitude pressurized negative ion oxygen supply mask, comprising a mask body 1 and a breathing chamber 2. The mask body 1 is made of a skin-friendly elastic fabric combined with soft silicone sealing edges, allowing it to closely conform to the contours of the human face. The inner side of the mask body 1 encloses to form a sealed breathing chamber 2, which corresponds to the human mouth and nose breathing area, providing a sealed operating space for pressurized air supply and exhaust gas discharge. The edges of the mask body 1 employ an elastic sealing structure to ensure airtightness in contact with the face and prevent pressurized gas leakage.

[0024] like Figure 2 As shown, the pressurized air intake module is embedded in the interlayer of the mask body 1. The micro turbine fan 3 adopts an ultra-thin and silent structure, with its air intake exposed on the outer wall of the mask body 1, allowing direct intake of ambient air. The outlet of the micro turbine fan 3 is sealed and connected to the pressurized airflow channel 4. The pressurized airflow channel 4 is a sealed, rigid air duct arranged along the internal curvature of the mask body 1. A negative ion generator 5 is fixedly installed in the middle section of the channel, and the end of the channel is connected to the breathing chamber 2. The negative ion generator 5 is used to ionize the air in the pressurized airflow channel 4 to generate negative oxygen ions. When the equipment is running, the micro turbine fan 3 mechanically compresses and pressurizes the rarefied air, increasing the oxygen partial pressure of the air; when the pressurized air flows through the pressurized airflow channel 4, it is ionized by the negative ion generator 5, generating activated air rich in negative oxygen ions, which is then sent into the breathing chamber 2. Mechanical supercharging increases the oxygen content per unit volume at the air source end, while negative oxygen ions optimize oxygen absorption and utilization efficiency at the human body end. The two work together to improve blood oxygen saturation and alleviate the hypoxia state at high altitudes.

[0025] In the altitude adaptive control module, the altitude detection unit 6 (which can be an altitude sensor or a barometric pressure sensor) is embedded unobstructed in the upper part of the outer side wall of the mask body 1, and is used to collect environmental altitude data and transmit it to the main control circuit board 7. Figure 3As shown, the main control circuit board 7 is electrically connected to the altitude detection unit 6, the micro turbine fan 3, and the negative ion generator 5, respectively. It outputs corresponding drive signals based on altitude data to adjust the speed of the micro turbine fan 3 and the output power of the negative ion generator 5. The main control circuit board 7 has multiple drive output ports, each with different output parameters. The main control circuit board 7 selects the corresponding drive output port based on the detection signal from the altitude detection unit 6 to drive the micro turbine fan 3 and the negative ion generator 5. In a preferred embodiment, the main control circuit board 7 has three drive output ports, corresponding to three altitude ranges: low altitude (below 3000m), medium altitude (3000m to 5000m), and high altitude (above 5000m). When the altitude detection unit 6 detects that the current altitude is low, the main control circuit board 7 selects the low-power output port, and the device operates at low power to reduce energy consumption and extend battery life. When a mid-altitude range is detected, the medium-power output port is selected, and the device operates at medium power to adapt to typical high-altitude hypoxic conditions. When a high-altitude range is detected, the high-power output port is selected, and the device operates at full power to maximize boosting intensity and negative oxygen ion generation. Each port automatically selects based on the altitude detection signal, precisely matching the oxygen supply needs at different altitudes. The aforementioned multi-port selection circuit can be implemented using conventional voltage comparators, analog switches, or integrated control chips. This invention does not propose any improvements to the internal programs or algorithms of such known circuits.

[0026] The exhaust module is located within the interlayer of the lower half of the mask body 1. The exhalation exhaust channel 8 and the pressurized airflow channel 4 are physically isolated, forming an independent dual-airflow structure. The inner port of the exhalation exhaust channel 8 connects to the bottom area of ​​the breathing chamber 2, facilitating the rapid collection of denser carbon dioxide exhaust gas; the outer port of the exhalation exhaust channel 8 is equipped with a one-way exhaust valve 9 made of silicone. The one-way exhaust valve 9 adopts a one-way check valve structure. When the wearer exhales, the exhaust gas pressure pushes open the valve plate to discharge outwards; when inhaling, the valve plate automatically closes, preventing the backflow of outside air and windblown sand impurities. Through this structure, the air inside the breathing chamber 2 is always clean and oxygen-sufficient, completely eliminating the secondary inhalation of exhaust gas.

[0027] The mask body also integrates a voice amplification module, which includes a miniature microphone 10 and an external miniature speaker 11. The miniature microphone is located on the side of the breathing cavity near the mouth, and the external miniature speaker is embedded in the side wall of the mask body. Both the miniature microphone and the external miniature speaker are connected to the main control circuit board. The miniature microphone collects the wearer's voice sound wave signal, which is then processed by the main control circuit board for noise reduction and signal amplification, driving the external miniature speaker to emit sound. This counteracts the sound wave attenuation caused by the mask structure, improves the volume and clarity of the wearer's external communication, solves the problem of communication difficulties after wearing a mask, and meets the communication needs of high-altitude outdoor work, team collaboration, and daily travel.

[0028] The mask body 1 also has an integrated flame-retardant and insulating isolation pad inside the interlayer, which completely wraps and isolates all electrical components such as the micro turbine fan 3, negative oxygen ion generator 5, and main control circuit board 7, so that they have no direct contact with the breathing gas in the breathing chamber 2 and the skin of the human face, thus eliminating safety hazards such as leakage, short circuit and electrical moisture.

[0029] This invention, an altitude-adaptive, high-altitude pressurized negative ion breathing mask, overcomes the shortcomings of existing high-altitude protective masks, such as insufficient oxygen partial pressure enhancement, poor altitude adaptability, waste gas accumulation, communication difficulties, and easy equipment damage. It increases the intake oxygen partial pressure through mechanical pressurization, and optimizes the body's oxygen utilization efficiency with negative ions. It automatically adapts to different altitude-deficient environments, achieving independent exhaust of waste gas and amplified voice transmission, scientifically and effectively alleviating altitude sickness and improving the user experience at high altitudes. This device is specifically designed for use in natural, open-air high-altitude environments. It is prohibited for use in enclosed, oxygen-rich, or artificially oxygenated spaces to avoid pressure imbalances that could cause fan overload, valve failure, and other equipment malfunctions.

[0030] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
