The surface in contact with the human body inside the nasal mask body can be a material that is harmless to the skin and has no allergic phenomena, such as pure cotton, silk, spandex, and modal cloth. The filter device adopts a detachable filter element. The filter element includes one or more combinations of PM2.5 filter element, harmful gas filter element, and toxic gas filter element. The harmful gas filter element includes one or more of the following filter materials The combination of species: sodium hydroxide, potassium hydroxide, sodium carbonate, to filter acids, aldehydes, ketones, halogenated hydrocarbons and other gases; boric acid, citric acid, sodium bisulfate, to filter alkaline gases; Manganese dioxide, hypochlorite, and sodium peroxide can filter out vapors such as cyanide, carbon monoxide, and heavy metals. The air state adjustment module in the air intake channel includes a detection and adjustment module for air composition, temperature, humidity, pressure and flow, and performs adaptive adjustment according to the detected air parameters. The medicine adding module can be put into various medicine additives that can be breathed through the respiratory tract, such as asthma medicine, respiratory disease medicine, etc. The medicine adding module is provided with a composition sensor, and the composition sensor is electrically connected with the embedded circuit board. The air outlet channel and the air inlet channel are made of non-toxic, light weight, pressure-resistant, corrosion-resistant, and harmless materials to the human body, such as PPR pipes. The filter device is also provided with a component sensor, which is electrically connected to the embedded circuit board, and can give an alarm before the filter core fails. An air flow sensor is provided in the nasal plug, which can display air status, filter function status or breathing status. The embedded circuit board adopts a single-chip microcomputer or a PLC control module, and is connected with a module, and the module includes all planes that can be displayed, such as a liquid crystal display.

The block diagram of the internal circuit connection structure of the embedded circuit board is shown in Figure 2. The embedded circuit board feeds back the measured data to the embedded circuit board. The circuit board can judge whether a person is exhaling or inhaling, thereby displaying real-time data to In the module, real-time alarms are performed, or the air pump is activated to perform corresponding "inhalation" and "exhalation" operations. The specific operation process is as follows:

When a person "inhales", the pressure sensor detects the change in the pressure in the nasal cavity, or other sensors in contact with the human body detect the signs that the human body begins to inhale, thereby recognizing that the nose starts to "inhale" and the "nose The instruction signal "Need to inhale" is transmitted to the embedded circuit board. The embedded circuit board forwards the signal to the air pump to do the "assisted suction" action. The outside air is filtered through the filter device through the air intake passage, and the fresh air filtered by the filter device passes through the air conditioning module, such as the medicament, fragrance adding module or other air state regulating modules, and enters the nasal cavity through the intake check valve and nasal plug. The human body absorbs it, and then achieves the purpose of inhaling the filtered new air into the nasal cavity.

When a person "exhales", the pressure sensor detects the change in the pressure in the nasal cavity, or other sensors that are in contact with the human body detect the signs that the human body begins to inhale, thereby recognizing that the nose starts to "exhale", and the "nose Need to exhale" command signal is passed to the embedded circuit board. The embedded circuit board forwards the signal to the air pump to do the "assisted exhalation" action. Press the air exhaled from the nasal cavity into the filter device, pass through the air outlet one-way valve, and press out through the air outlet channel. Then the purpose of pressing the filtered new air out of the nasal cavity is realized. Depending on the specific application, it is optional to pass through the filter device, such as infectious disease control and so on.

Generally speaking, the nasal mask filters the air through the filtering function of the filter element and other chemicals. When a person inhales, the natural air passes through the negative pressure difference of the one-way valve and is adjusted by the air state adjustment module, so that the user can enjoy fresh air up. When the user suffers from certain infectious respiratory diseases, when the user exhales, under the positive pressure difference of the outlet check valve, the inhaled gas is filtered by the filter device and then diffused to the outside. In this way, the user can conveniently breathe in the nasal mask. Chest tightness, dizziness will not occur.

The nasal mask designed according to the invention is particularly suitable for weather with serious environmental pollution and other daily and medical purposes.
