[0044] A method for providing a passenger with an ionized air purification system in the form of a respiratory nasal mask, by adapting an intelligent human respiratory filter device to the passenger's face to filter particles, airborne substances, dust, pollen, odors, PM2.5, pollutants, bacteria and viruses, toxic chemicals, smoke or tobacco smoke entering the passenger's respiratory system in a public transportation system, wherein the public transportation system includes trains, airplanes, buses, ferries and taxis, and the intelligent human respiratory filter device is powered by a power socket including a universal serial bus power socket installed within 2 meters of the passenger's seat.

[0045] According to the intelligent human respiratory filter device of the embodiment of the present application, the working principle is:

[0046] The ionization needle module 16 receives power from the ionization voltage output 27, and ionization occurs when negative ions 18 are released from the tip 17. The negative ions 18 leaving the tip 17 form a directional ion flow 33 toward the flow direction. These directional ion flows 33 form an ion concentration region 29 between the tip 17 and the positively charged metal front collector 19 and the positively charged main collector plate 45.

[0047] When the airborne particles 54 pass through the ion concentration region 29, the negative ions 18 will attach to the airborne particles 54. The airborne particles 54 will then be negatively charged and will be attracted to the positively charged metal front collector 19 and the positively charged main collector plate 45.

[0048] When the metallic front collector 19 is bombarded by negative ions 18 produced by ionization at the tip 17 , an electric flux field 58 is generated from the outer surface of the non-conductive front shield 24 .

[0049] When the ionization flux sensing device 56 is working, the sensor power switch 37 is in the power-on position and the sensor power LED 38 is lit. When the sensing antenna 57 senses the electric flux field 58 or negative ions 18, it will be converted into a small current and sent to the sensor electronics unit 39 of the ionization flux sensing device 56. The small current will be amplified by the sensor electronics unit 39 to more than 50,000 times to be able to light up the sensor flux intensity LED 59.

[0050] The sensor flux intensity LED 59 will go from not lit at all to dim or very bright depending on the initial amount of received electric flux field 58 or negative ions 18. The intensity of the sensor flux intensity LED 59 from none to very bright provides a distinct visual observation for the user to identify the presence of ionization.

[0051] Figure 5 The air flow path during inhalation of a user of the intelligent human respiratory filter device according to an embodiment of the present application is shown, that is, when the user 1 inhales, the air flow path from the environment 22 to the nasal mask chamber 23 through the intelligent human respiratory filter device 2.

[0052] The suction force of the moving air flow 53 comes from the suction force of the user 1 and the pressure increase of the electric fan 8.

[0053] Air flow 53 is drawn from the surrounding environment 22 into the pre-filter ionization zone 6, along the air flow path 43 through the front edge opening 13 and through the ion concentration zone 29. The air flow 53 will then pass through another ion concentration zone 29 located within the main filter ionization zone 42, and then through the electric fan 8. The electric fan 8 increases the air pressure within the mask chamber 23 to a pressure higher than that of the surrounding environment 22. This allows the user 1 to inhale more effortlessly than breathing directly from the ambient air pressure.

[0054] Figure 6 The light emitting diode (LED) ultraviolet UV exposure mechanism of the intelligent human respiratory filter device according to an embodiment of the present application is shown, that is, the ultraviolet irradiation sterilization mechanism of the intelligent human respiratory filter device 2.

[0055] The germicidal wavelength LED 30 generates ultraviolet rays 46, which irradiate the entire surface of the positively charged main collector plate 45. As a result, the particles 54 in the air are attracted and stay on the surface of the positively charged main collector plate 45. The main collector plate 45 and the particles 54 will be exposed to continuous ultraviolet rays 46.

[0056] According to the intelligent human respiratory filter device of the embodiment of the present application, the ultraviolet rays or ultraviolet radiation are referred to as UV; the light emitting diode is referred to as LED; the universal serial bus is referred to as USB. PM2.5 refers to particulate matter (PM) with a diameter of less than 2.5 microns in the atmosphere.

[0057] The intelligent human respiratory filter device 2 has an elastic nasal mask 5 and a nasal mask shell 9 as a nasal mask body, a nasal mask cavity for surrounding the user's mouth and nose, and a filter cavity for installing an ionized air filter element; the headband 50 is wrapped around the user's ears and around the back of the head to cover the user's nose and mouth.

[0058] The light emitting diode with a sterilization wavelength generates ultraviolet light with a wavelength between 200nm and 400nm for sterilization and disinfection.

[0059] The ionization flux sensing device is used to detect the presence of ions generated by ionization in an electric flux field, and the sensor electronics unit with a battery amplifies the electrical energy received at the sensing antenna by more than 30,000 times to illuminate the sensor flux intensity LED (light emitting diode). The ionization flux sensing device further includes a housing cover; a sensing antenna; a sensor power switch; a sensor electronics unit with a battery; a light emitting diode (LED) that lights up when the power is turned on; and a light emitting diode (LED) that displays the sensor intensity.

[0060] It should be understood that according to the intelligent human respiratory filtration device of the embodiment of the present application, the size, quantity, shape and arrangement of various components, such as the ionization needle module, the metal front collector, the electrical collector, the positively charged main collector plate, the power connector, the wire, the wire length, the material used, the filter size, the filter gap, the size of the nasal mask and the size of the seal can be changed without departing from the spirit and scope of the present invention, the type of temperature sensor, the type of air pressure sensor, the type of wireless transmission system, the type of data receiving system can be changed. Similarly, the size and contour of the nasal mask can be changed relative to adults, children, men and women, etc.

[0061] The intelligent human respiratory filter device according to the embodiment of the present application requires a low-voltage DC power supply when in operation, including a power supply provided by a common mobile phone battery pack or a USB power socket, etc. As an electronic nose mask with directional ion air filtration control, it is the most ideal substitute for the traditional filter paper nose mask.

[0062] According to the intelligent human respiratory filter device of the embodiment of the present application, multi-stage electron ionization technology and electrostatic field are used to remove substances, PM2.5, dust, pollen, pollutants, bacteria, viruses, toxic chemicals, smoke and tobacco smoke in the air inhaled and exhaled by the human body. It also has ultraviolet sterilization rays, which are suitable for any substance captured on the surface of the positive collector. It can use a miniature electric fan as an airflow drive system to interact with the human breathing action to make the inhalation and exhalation pass through the electronic filter element. The entire filtration system is lightweight, and positive pressure air flows into the nasal mask. It is also equipped with an ionization flux sensor for users to verify whether there is ionization in the device. It has a very high use value for daily use, especially for the tourism industry, so that passengers can sit together safely when taking airplanes, buses, ferries, trains and similar public transportation.

[0063] According to the intelligent human respiratory filtration device of the embodiment of the present application, as an intelligent dual-stage ion air filtration system installed on a nasal mask, the beneficial effects are:

[0064] The elastic nose mask and the front pre-filter cover unit cooperate with other components such as the main filter unit to prevent the human respiratory filter device from being affected by wind, so that it can be used in dynamic scenes with fast air flow such as windy environments.

[0065] The generated ions are concentrated in the area of ​​the air flow channel and the direction of travel of the ions is controlled, so that the overall air filtration efficiency is improved.

[0066] The addition of light-emitting diodes with bactericidal wavelength function into the nasal mask constitutes a micro-sterilization system, which can sterilize and disinfect the collected organisms including bacteria and viruses, thereby improving the safety of use.

[0067] The fan structure in the nasal mask is combined with other components to provide positive air pressure inside the nasal mask, which can help users balance the air resistance during inhalation, and users will feel that breathing is easier.

[0068] The ionization flux detection function can be provided to the user so that they can easily verify that the mask is operating without problems. Unlike mechanical media filtration, ion air filtration does not allow the user to easily detect whether ionization is actually occurring and whether the mask is operating as expected. The solution of the present invention solves the user's concerns.

[0069] The nasal mask integrates an intelligent data acquisition system, equipped with an air pressure sensor, a temperature sensor, and a data calculation system, and then transmits the data to external data acquisition devices and mobile phones through a wireless data transmission system. It helps nasal mask users better understand their breathing frequency and volume as well as facial surface temperature.

[0070] Since most public transportation systems (such as airplanes, buses, trains and ferries) generally have (Universal Serial Bus) USB 5VDC power supply, through the setting of the USB connector, it can be operated and used using the USB power supply, which improves the convenience of use.
