Description

[Replenishment based on Rule 26 23.04.2021] Mask device with fan and transparent mask device

Mask device with fan motor and sterilizer

Conventional masks, especially high-performance masks, have difficulty breathing, are hot and steamy, and even those using bactericidal and antibacterial cloths have limited effects. There is also a mask with an exhaust valve, but the effect is limited, and the mask itself has no effect and disperses bacteria.
Also, a mask that makes the area around the mouth transparent to show the movement of the lips to the other party has been devised, but it is stuffy because it blocks the air. In addition, masks with fans are also on sale, but the effect is limited by simply doing inspiration or exhalation with a fan motor, and there are cases where the exhaust goes out directly, it just makes the person's breathing a little easier. It's simple.

Make it possible to see and understand facial expressions, mouth movements, and vocalizations even with a mask. Even with the performance equivalent to N95, it eliminates suffocation. Furthermore, subtitles, translations, sign language, etc. are also displayed on the display device for persons with disabilities, the elderly, and patients. Even with the mouse shield and face shield type, a fan and a filter are attached to produce an effect similar to a mask.

Hereinafter, the fan refers to a fan motor or a piezoelectric blower.
The fan is placed on the mask or in a device that covers the mask or in a mask-shaped case to assist the fan's wind or pressure with breathing from the mask or alternative filter. LEDs and display devices are attached to the device that covers the mask to express facial expressions, mouth movements, and vocalizations. Even with the mouse shield and face shield type, the fan and filter have an effect similar to that of a mask for breathing. The utterance of the mask wearer is picked up by a microphone and displayed on a speaker, display device, or LED by signal processing. For signal processing, it is also possible to process signals by connecting to the Internet using a smartphone, a microcomputer, or wireless means.
The operation of the fan may be a simple operation that assists breathing as forward / reverse rotation by operating the fan at regular intervals or at regular intervals, or by operating the fan in forward / reverse rotation or by stacking two fans and operating one of them. , Temperature, CO2, air volume, air pressure sensor, etc. can be detected and controlled according to breathing.
The power source is a battery, and even if it is a control device, it is installed in another place such as a mask device or waist. A small camera may be installed on the mask device to display the image of the mask wearer on the display device.

Since it is important to display the movement of the mouth in sign language, if the mouth is hidden, the movement of the mouth is displayed on the display device.

It is also good to install an ultraviolet or ozone generator. For the operation of the fan and the sterilizer, a pressure sensor may be attached to the ear strap or a power switch may be provided. Further, it may be operated for a certain period of time or intermittently.
Similarly, the fan itself may be installed in addition to the mask and an air tube may be used.

By seeing and understanding facial expressions and mouth movements, the problem with masks can be solved. It's easy to breathe with a fan, it doesn't get stuffy, and the glasses and face shield are hard to fog. The utterance is easy for the other party to understand. Hearing impaired and foreigners can understand.

By displaying the spoken words that can be clearly communicated to the other party through the speaker, further translating and displaying, displaying in sign language, displaying as mouth movement, etc., the inconvenience of the mask is eliminated and high functionality is added.

The description of FIG. 1 and all other figures and the description of the present invention as a whole are also described together.
It is the figure which put the mask cover 2 on the mask body 3. There is a gap between the mask cover 2 and the mask body 3, but the fan 1 still has the effect of assisting breathing, but if only the edge of the mask cover 2 is sealed with the mask body 3, strong wind pressure will be applied to the mask body 3 and breathing will occur. The effect of making it easier is enhanced. The shape of the mask cover 2 is adjusted to match the shape of the nose, but the mask cover 2 avoiding the nose as shown in the attached figure may be used. The sterilizer 7 has the effect of sterilizing the air inside the mask cover 2 and the mask body 3.

Hereinafter, the present invention will be described as a whole in this paragraph.
The drive battery, control device, and the like of the present invention may not be installed on the mask cover 2 or the fan 1, but may be installed in another place using the electric wire 11 as shown in FIG. It may be fixed to the ear strap, may be installed on the back of the head if the ear strap is tied at the back of the head, or may be fixed to the pocket or belt of the wearer of the present invention.
In the explanations and figures of the present specification, the explanations and figures for the driving battery, the control device 17, the electric wire 11, the smartphone, and other devices of the present invention are almost omitted. Wiring to them is also omitted, but it is not essential for the explanation of each figure. Figure 15 is an example. The ear straps are also almost omitted as well. This is because it is clogged and can be installed as described above. The LED 20 acquires the voice of the mask wearer 22 with the microphone 18, processes the signal with the control device 17, and blinks according to the utterance. Multiple LEDs 20 may be arranged side by side to form an audio level meter.

Even if the mask cover 2 is fixed to the mask body 3 with adhesive, tape or face tape, a clip is attached to the mask cover 2 and fixed by sandwiching a part of the mask body 3, or a string is attached and fixed to the ear strap 4. Alternatively, an ear strap may be attached and fixed. In addition, a method of tying with the back of the head instead of the ear strap may be used. The ear strap may be like a belt.

In the present invention, a flexible material such as rubber or silicone resin is used for the edge of the mask cover 2 as needed or in order to apply the wind pressure of the fan, and the part other than the edge is deformed to the wind pressure of the fan 1. A material with a hardness that does not prevent it is good, for example, a material with a thickness of about 1.5-3 mm of acrylic.
The mask body 3 may be an air filter instead, and it may be removable to the mask cover 2 using a net-shaped plastic plate, but in that case, it is better to install it inside the above-mentioned silicone resin. Alternatively, even if it is fixed to the edge of the mask cover 2 with an adhesive, tape, or surface tape, it does not significantly deform to the wind pressure of the fan 1 to the filter or the wind pressure of breathing. The clogged mask cover 2 and the mask body 3 are integrated. Alternatively, the filter may be installed on the fan 1 with an adhesive, tape, or surface tape. Alternatively, the fan 1 and the filter may be installed in another place by the air pipe from the mask cover 2.

Also, the curve of the mask cover 2 creates a gap inside the mask body 3 or the filter instead of the mask body 3, which is an image of covering a bowl to create a gap, even in the air passage. Yes, the smallest part should be about 1 cm, and the others should be about 2 cm or more. The shape of the mask cover 2 may be the shape of a mask called a commercially available 3D mask. The mask body 3 can be used in the present invention even if it is a 3D mask or a mask having a similar large beak-like shape.

The present invention has the effect of facilitating breathing even if breathing and fan 1 control do not match completely and accurately. This is also because the air in front of the mouth is replaced, and the wind pressure of the fan 1 is applied to the filter or the mask body 3 to eliminate the stagnation of the air. Furthermore, the mask wearer breathes according to the wind pressure and fresh air. Because there are times when it matches.
Sensor 5 detects the breathing of the mask wearer with temperature, humidity, CO2, air volume, air pressure sensor, etc., and / or simply operates the fan for a certain period of time, or reverses the rotation of the fan 1 for a certain period of time. Fan 1 may be controlled. The operation in this fixed time may be when the intake / exhaust discrimination by the sensor 5 is not accurate, or when the fan 1 is controlled without using the sensor 5. In addition, the control of the fan 1 has an effect on assisting breathing even if the rotation is forward or reverse or only one of the rotations is used, and the operation only for either of the breathing is effective. Forward and reverse rotation may be handled by installing two fans facing each other and operating either fan. Further, the sensor 5 may be installed on the outer surface and the inner surface of the mask cover 2, and the respiration may be determined by the difference between the detection signals of the two sensors 5 to control the fan 1.
Fan 1 is the same even if a piezoelectric blower is used.

The operation of the temperature sensor is about 37 degrees for exhalation and 40 degrees for heat generation, but if the outside temperature is not exactly the same, it is possible to detect the difference in temperature and control fan 1 according to breathing. be. Alternatively, a temperature sensor and a humidity sensor may be used, and if the humidity is high and the temperature is about the body temperature, it may be determined as exhaled breath and the fan 1 may be controlled.
The control method when each sensor is used will be described below, but each sensor can be combined with other sensors for more accurate control. For example, the combined use of a CO2 sensor and a pneumatic sensor.
In the case of a CO2 sensor, the CO2 concentration in the air is 0.041%, the exhalation is 1% even at rest, and the resolution of a commercially available CO2 sensor is about 0.001%, so it is easy to distinguish breathing and the CO2 concentration is above a certain level. If it is high, it is judged that exhalation is coming out or the air in the mask cover 2 should be discharged, and the fan 1 is operated. And the rotation of fan 1 is set to the intake direction from the outside air.
Further, when the CO2 concentration is higher than a certain time, the fan 1 may be operated for the exhaust for a certain period of time, and the fan 1 may be operated for the intake air for other than the certain time. Furthermore, the control of fan 1 is the same for the following other sensors.
In the case of an air volume sensor, for example, a MEMS small air volume sensor can measure wind speed and wind direction. The exhaled air from the mask body 3 is detected by the wind speed and direction. For reference, at rest, the inspiratory time is about 1 second and the expiratory time is about 0.4 seconds, and the expiratory time is often faster than the inspiratory time even under other conditions.
When using an air pressure sensor, measure the air pressure inside the mask cover.
The air pressure inside the mask cover rises above a certain level due to exhalation → the fan is discharged → the air pressure drops by a certain amount, but the fan discharge operation remains the same → stop exhaling or inhale → the air pressure reaches a certain amount Since it goes down, it is judged whether it has stopped spitting or sucking → Control the motor in the direction of intake → The air pressure rises a little, but the fan operates as it is → If the air pressure rises above a certain level, it will be exhaled --- Repeat this .. Fan 1 can be controlled only for either exhalation or inspiration for detection or determination of changes in atmospheric pressure.

If there is one fan on the entire surface of the mask cover, the fan 1 should be directed under the face so that the exhaust does not go to the front of the face, or the wind direction may be so with a wind direction plate or a member that allows air to flow. However, it may be in the left-right direction of the face. The wind direction device of FIG. 7 may be used.

If the sterilizer 7 is placed inside the mask cover 2, there is no adverse effect on the eyes due to ultraviolet rays even if the wavelength is not 222 nm, and the mask is always sterilized. The cloth on the face side of the mask body 3 should be a cloth that blocks ultraviolet rays so that it does not pass through the mask and affect the face, or the amount of ultraviolet rays should be reduced. Furthermore, when the mask is removed, attach a pressure sensor or strain sensor to the mask body 3 part of the ear hook string 4 or stop it with a clip, and use the output signal or operate the manual switch to remove the mask. When the mask is removed, increasing the output of the sterilizer is good for sterilizing the mask, and it may be operated for a certain period of time or intermittently, or when the mask is worn.
In addition, if an operation switch is installed on the fan 1 or the sterilizer 7, the mask may be attached by operating the switch.
Ozone generation by ultraviolet rays is more effective for sterilization, but in that case, ozone generation is possible if the wavelength of ultraviolet rays is 230 nm or less. It may be possible to use ozone after detecting that the mask has been removed and / or to use ultraviolet rays in combination. An ultraviolet emitting device that does not generate ozone may be used. LEDs are suitable for generating ultraviolet rays, but there are also fluorescent tube types. There is also data that ultraviolet rays at 222 nm can be sterilized without adversely affecting the human body.
The Occupational Safety and Health Standards for ozone stipulate that the concentration of ozone in the air in the room is 0.1 ppm or less, which is considered to be an acceptable concentration for the working environment and has no effect on the human body. Alternatively, as described above, ultraviolet rays and ozone may be generated or strongly generated only when the mask is removed.

By the way, the weight of a general mask on the market is 8g or more with a string, the outer diameter is 16mm with a fan * 1.2g with a thickness of 4mm, the air volume is 0.012 (cubic meter / min), the static pressure is 5-6Pa, and the outer diameter is 25mm * with a thickness of 10mm. 7g, air volume 0.05 (cubic meter / min), static pressure 30Pa. If necessary, install two fans on top of each other, or operate the two fans on the left and right sides of the mask at the same time by rotating them in the same direction to further increase the static pressure and improve the effect of making breathing easier.
The average ventilation volume per time for a person weighing 50 kg is about 0.5 L, but 0.5 L * 20 = 0.01 cubic meter / min for 20 breaths / minute, and the 1.2 g fan for air volume is sufficient, but air A fan with a high static pressure is good for applying strong wind pressure to the filter or mask.

There is also a method of installing a heat exchanger, a heat sink, etc. in the mask cover or in the fan to allow intake and exhaust to pass through. It may be a heater or a Pelche element.

In addition to the methods described above, the automatic start and stop of the present invention may be started when the detected concentration of the installed CO2 sensor is about the exhalation level, and may be stopped when the concentration is not present for a certain period of time. good. Similarly, the automatic start and stop using the movement of the barometric pressure sensor and the air valve described separately may be the same as the operation of the above CO2 sensor.

Further, by attaching the display device 21 to the mask cover 2, the display device 21 can supplement even if the mouth of the mask wearer 22 is hidden. Even if the mouth is hidden, the movement of the mouth may be displayed on the display device 21. It doesn't have to be a clogged transparent mask cover, it can be an animation, you can switch between several images of the lips and move the lips according to the utterance, or the gap between the mask body 3 and the lips is plastic. A small camera for taking a picture of the lips may be installed in a space created by the net, and the image may be displayed on the display device 21. In FIGS. 1 to 3 and 5, the display device 21 may be installed with a slight gap in front of the fan 1, or may be installed near the end of the mask cover 2. The display device 21 can be replaced with a smartphone. The microphone of the smartphone picks up the voice of the wearer of the present invention and displays it on the display of the smartphone by signal processing. It is better to create and install an application so that the smartphone can replace the display device 21. Create an application to capture and display translations obtained on the Internet from a smartphone via Wifi connection, etc., and display them on the smartphone or display device 21. The display device 21 may be a dot matrix.

The position of the fan 1 should be on the side of the mask cover 2, the mask cover 2 should be transparent, and the center of the mask body 3 should be made of a transparent material so that the mouth and nose can be seen. The display device 21 can also be installed at the bottom or side of the mask, avoiding the fan.
In all figures, it is actually more curved or curved to fit the shape of the face.

Below, the data and considerations regarding the amount of ultraviolet rays are described.
1. As an example of sterilizing power, according to the test results of the Ministry of Health and Welfare and the National Institute of Public Health conducted using a 15-watt germicidal lamp, the germicidal lamp takes 60 seconds to obtain a germicidal rate of 99.99% or more against Escherichia coli. In contrast to this germicidal lamp, which requires 1 minute), the sterilizing power of the sun's rays is increased. As a result, it took 64 minutes to sterilize 99.99%.

2 ... UV-LED output, for example, a commercially available 5mmΦ * 8.7mm one has a radiant flux of 4mW, and 15 2θ1 / 2 (deg) 365nm 3.4V 20mA conversion efficiency is 5%. It is thought to be less than 1/1000 of the sunlight that reaches the ground. For example, even if you place about 4 of these in the mask cover of the present invention, there is almost no risk of sunburn, and since some of the fabrics are UV-CUT, use them for the part that hits the face of the mask. It is also good ... If you choose a product with a UV blocking rate of 90% or more, or UPF40-50 +, you can efficiently take measures against UV rays and sunburn.
If the inside of the mask cover is treated with ultraviolet rays such as plating to reflect ultraviolet rays, the ultraviolet rays can efficiently irradiate the entire mask.
In addition, a commercially available 3W class ultraviolet LED has a radiant intensity of 180 mW or more and a half angle of 140 °, so such a large LED may be used. As a germicidal lamp, an ozone ultraviolet bulb with an output of 185 nm and 0.12 W, which is about the size of a glow lamp, or an ultraviolet bulb that does not generate ozone may be used.

In FIG. 2, the fan 6 with a sensor is made of double-sided tape or a string, or a net is attached under the fan 6 with a sensor, and the net is used to fix the fan 6 to the mask body 3. This sensor is sensor 5, and the control of the fan by it is described in another explanation. Even if the fan 1 is used without the sensor and only the inspiration or exhalation from the mask body 3 is used, it has the effect of assisting breathing. Even if the operation is not continuous or intermittent, or if the fan 1 is alternately reversed for a certain period of time, there is an effect of assisting breathing.
Even if the fan 1 is installed on a part of the mask body 3 as shown in this figure, it has the effect of assisting breathing.
Not limited to this figure, the sterilizer 7 is not essential.

FIG. 3, there is no gap between the edge of the mask cover 2 and the mask body 3, and there is no sensor 5, but the case where it is in FIG. 2 and the case where it is not are explained, which are the same.
Not limited to this figure, even without a fan, simply installing a sterilizer 7 or a sterilizer such as an ozone generator on the mask is effective against bacteria and viruses.
The sterilizer 7 is installed by sticking it in the mask cover, so it is not shown as a dotted line.

In Fig. 4, tube 8 is a tube of air from fan 1 and fan 1 with air filters installed separately.
If the mask body 3 is a 3D mask, open a pinhole and install a pinhole camera there, or install a small camera inside the mask body 3 and control the signal of the camera wirelessly or by wire. Send to the device The control device displays the movement of the lips on the display installed in front of the mask cover 2, or receives the signal with a smartphone and displays the movement of the lips by signal processing to show it to the other party. This is possible in the present invention because it reduces the stuffiness in the mask during breathing. In addition, the pinhole can be completely closed with adhesive or adhesive tape to prevent the virus from passing through.

In FIG. 5, the lower part of the fan 6 with a sensor is curved and molded so as to cover the mouth and nose of a person so as to be in close contact with each other, and rubber or the above-mentioned silicon resin is used to give elasticity. Further, the sensor 5, the battery, the sterilizer 7, and the control device may be built in the fan 6 with the sensor. The mask body 3 is an air filter so that it can be easily replaced with double-sided tape.

FIG. 6 and the electric wire 11 are electric wires 11 for installing the control device, the battery, etc. necessary for the function of the mask cover 2 in another box when they are not mounted. The box is installed in the pocket or belt of the mask wearer, or in the place where the ear strap or the ear strap is turned around the back of the head. A smartphone may be installed in the box as one of the control devices.

For example, if one fan 1 is dedicated to exhaust and is operated during exhalation, and if one fan 1 is stopped or inhaled, the air before the mask will be fresh, but two fans 1 will be introduced. By rotating according to breathing, wind pressure is applied to the mask body 3 and breathing becomes easier.

Further, the display device 21 may be attached to the front surface of the mask cover 2, and the display device 21 displays the mouth without making a part of the mask cover 2 and the mask body 3 transparent.

In Fig. 7, fan 1 may be equipped with a wind direction device in this way. Below the fan 1 is the mask side, which is exhausted by the exhaust valve 12 opened by the pressure of the exhaust from the mask of the fan 1 and / or the wind pressure of the exhaled air from the mask. Since the exhaust valve 12 is installed so as to cover the outside of the hole made in the wind direction device 14, it is closed in the case of reverse air.
Similarly, since the intake valve 13 is installed so that the valve opens inside the wind direction device, the valve is opened by the wind pressure of the intake air from the mask and / or by the pressure of the air blown to the mask of the fan 1.
This allows fresh air to be taken in by making the wind directions of exhalation and inspiration different, and the valve changes the operation of fan 1 as a sensor of exhalation or inspiration.
In this figure, the device that detects the opening and closing of the valve is omitted, but as shown in Fig. 7b or Fig. 7c, for example, a photo interrupter 16 is installed to detect the movement of the valve and control the rotation direction and operation of the fan 1. .. The photointerruptor 16 can detect respiration only by installing it on the intake valve 13, and conversely, it can detect respiration only by installing it on the exhaust valve 12.
Alternatively, the rotation of the fan 1 may be only exhaust, and conversely, the rotation of fan 1 may be only intake.

For the photo interrupter 16, both the intake valve 13 and the exhaust valve 12 are made of a material or color that does not allow outside light to pass through the wind direction device 14, and a photo sensor is installed inside the wind direction device 14 to simply place the valve. It is possible even if it is not the photo interrupter 16 by detecting the input of external light due to movement.

Figures 7b and 7 are rotated and the exhaust valve 12 is in front. The photo interrupter 16 is used to detect the opening and closing of the exhaust valve 12 in a non-contact manner. If the valve of the exhaust valve 12 is opaque, the valve blocks the passage of light from the photo interrupter 16, so that the opening and closing of the valve can be detected. If the exhaust valve 12 is not open, it means that breathing is stopped or inhaled, so the rotation of fan 1 is controlled in the forward and reverse directions to assist breathing.

The photo interrupter 16 is shielded from the surroundings including the valve to prevent ambient light from entering, but the photo interrupter 16 is surrounded by an opaque plastic plate to prevent external light from entering, especially when the valve is opened. It's good if it's good.

The operating principle is the same as in Fig. 7c and Fig. 7b. A cross-sectional view of the inside of the wind direction device 14, the photo interrupter 16 and the intake valve 13 are on the other side.
Since the photo interrupter 16 is installed inside the device, it is not easily affected by external light, but if necessary, it may be surrounded by an opaque plastic plate.

Instead of the photo interrupter 16, the air volume sensor can be installed near the intake valve 13 and / or the exhaust valve 12, or a CO2 sensor can be used.
Furthermore, not limited to this figure, the detection of respiration can also detect the arrest of respiration. If the sensor 5 is not detected for a certain period of time, for example, a buzzer may be sounded or a signal may be transmitted wirelessly as an abnormal situation. It can also be used for sleep apnea syndrome.

In Fig. 8, fan 1 is installed on mask cover 2.
The number of fans is not limited to two. The opposite side surface may be covered with a shielding plate 15, or even if the shielding plate 15 is not covered at all on both sides, there is an effect of facilitating breathing by exchanging air before the mask. Batteries may be installed on the opposite side, on the upper surface of the mask. It is a good idea to fill the gap between the mask cover 2 and the mask body 3 other than the fan 1, take in the outside air for the intake of the two fans 1, and take in the air from the mask body 3 for the exhaust and apply wind pressure to the mask body 3. Make it easier to breathe. Of course, it depends on the control of the fan 1 of the control device by installing the sensor 5.

Figure 9, actually curved to match the shape of the face. Fan 1 is installed on the left and right of mask cover 2. The control method of the fan 1, the sensor 5, the battery, etc. are also as explained in FIG. 1, which is also the explanation for all the figures.
In this case, it is an example in which the present invention is installed only in the mouth while avoiding the nose. The mask body 3 is responsible for the nose.
Filters are attached to the left and right fans 1.

In FIGS. 9 and 10, the fan 1 is installed at the left and right ends of the mask cover 2 or either of them, but the filter is located about 1-2 cm inside the fan at the left and right ends of the mask cover 2. It is also good to make a filter chamber by sandwiching it with a resin net and installing it in the mask cover 2 without any gaps. It will be a filter with a larger area than attaching a filter to the fan.
Alternatively, the installation of the fan and the filter may be reversed. It is a structure in which the filter device 27 of FIG. 13 is provided on the left and right sides of the mask cover 2 due to clogging.

Further, when the mask cover 2 is made transparent and the central portion of the mask body 3 is made transparent as shown in FIGS. 16 to 18, the mouth of the mask wearer can be seen. This may also be in the shape of a 3D mask that covers the mask cover 2 up to the nose.

Alternatively, the mask cover 2 may be shaped like a 3D mask that covers the nose without the mask body 3, and may be attached to the face with an ear strap.

As in Fig. 10 and Fig. 9, it is horizontal to hit the face, but it is correct that it curves like a 3D mask along with the mask body 3 and the fan cover 2 to match the face. The fan 1 is installed only on the right side of the mask cover 2, but fans may be used on both sides as shown in Fig. 9, but in this case, the fan 1 has an intake / exhaust function. Fan 1 may be rotated in the forward and reverse directions, or two may be stacked in the opposite direction to form one, and intake and exhaust may be performed by driving each fan. The control device 17 of the fan 1 is provided on the left side of the mask cover 2.
As shown in FIG. 9, the mask cover 2 may be installed only on the mouth while avoiding the nose, or the portion of the mask cover 2 that touches the nose may be deformed into the shape of the nose.

In Fig. 11, fan 1 is installed under mask cover 2.
The nose may be covered by the mask body 3 or the mask cover 2 may cover the nose.
The microphone 18 is installed on the mask body 3 side of the mask cover 2 toward the mask body 3, picks up the voice of the mask wearer, and outputs sound through the speaker 19 with a built-in amplifier. The microphone 18 is connected to the speaker 19 with a built-in amplifier and the LED 20. The drive circuit of LED20 is built in the speaker with built-in amplifier. The LED 20 may be installed in the speaker 19 with a built-in amplifier.

FIG. 12, the display device 21 may be a liquid crystal panel, a smartphone, or an LED dot matrix. The display device 21 can display the movement of the mouth, display characters, display sign language, display translated foreign language characters, and the like.

In the display of the movement of the mouth, the mouth of the mask wearer is selected or processed from the captured data in the animation or the mask wearer's mouth is displayed like the mask wearer's mouth by the signal of the microphone 18. The following methods can be considered.
1 ... Temporarily, the mouth is closed = 1, half-open = 2, wide-open = 3, and the voice flows from the speaker 19, so it feels like you are actually speaking. This is the method used in animation. .. Select 1-3 based on the change in the signal from the microphone 18, but set the voice level to 1 for silence, 2 for utterance, and 3 for high-level utterance. This may be divided into 1 to 3 by determining the magnitude of the amplified signal of the microphone signal. The signal can be easily understood by driving the LED and blinking at the same time, but it may be displayed by some LEDs like an audio level meter. For example, in an example using an LED dot matrix as a display device, mouth movement 1 is 2 rows in the Y direction * 11 LEDs in the X direction, and 2 is 7 rows in the Y direction and does not light up as if the central part was opened * X There are 11 directions, and 3 is the same lighting as 2, and can be displayed with a total of 121 LEDs in an 11 * 11 LED matrix. Placing a sheet that diffuses light in front of the LED dot matrix feels more like a mouth.

2. The vowels of utterances are analyzed and extracted in real time, and five types of mouth shapes are prepared and displayed on the switching display device 21.

3. Real-time voice analysis of voice is performed, signal processing is performed so that the movement of the mouth is reproduced by software, and the signal is displayed on the display device 21.

4 ... If it is a 3D mask, there is a gap between it and the mouth, and a camera is installed there, and it is displayed as it is on the display device 21. The camera is also equipped with a light emitting device for shooting.

To display characters, the signal of the microphone 18 is processed by the control device 17 or a smartphone. In the example of the Internet environment, there is an automatic transcription function for Google Docs, so it is also good to use a smartphone as the signal processing and display device. You can also use translation software and the Internet environment to translate into foreign languages. Signals are exchanged between the smartphone and the present invention via a USB terminal or wirelessly.
In addition, since some portable translators can be used without using the Internet, the voice before translation and the information after translation are displayed on the display device 21 or a smartphone. Further, the voice analysis may be converted into sign language and displayed on the display device 21. The technology for converting to sign language is currently easier to display by hand for the 50 hiragana sounds than for words, but sign language is better for displaying sign language using the face and upper body as well. In that case, the signal processing is made more complicated and the face and upper body are displayed on the display device 21. In that case, signal processing using the Internet with a wireless connection is also convenient.

The speaker 18 may be mounted on the display device 21. LED20 is not always essential.

Connections to each part, electronic parts, boards, control devices, batteries, etc. are omitted not only in this figure, but even if they are installed inside the mask cover 2, the cord can be taken out from the mask cover 2 and the chest pocket or waist belt can be used. It may be installed in.

It is a display device 21 of FIGS. 12a and 12. The star to the left of the letter flashes in time with the vocalization. To the right, the signal from the microphone 18 is analyzed by voice and displayed as characters. At the same time, the translation is in English here. Below that, the movements of the lips and the mouth of the person wearing the clogged mask are displayed. The mark of the hand below it is the display position of the hiragana Japanese syllabary sign language, which is not an accurate sign language in this figure. It is also possible to display full-scale sign language including the entire arm, body, and face.

FIG. 13, the filter device 27 comes under the mouth of the wearer of the mouth shield 25. The filter device 27 is a closed space, and either intake or exhaust from the fan 1 passes through the filter 26. The sensor 5 detects the breathing of the mask wearer, and the control device 17 operates the fan 1 by signal processing. Furthermore, the mouth shield 25 may be extended above the eyes to have the function of a face shield. In that case, the mouth shield 25 may be attached and fixed to the forehead.
Further, the display device 21 may be installed on the left and right or below the mask wearer's mouth, in which case the mouth is visible and the display of the mouth of the display device 21 becomes unnecessary. When the display device 21 is installed in the part of the filter device 27, it can display a wide range on the left and right.
The filter device 27 can be turned upside down with the fan 1 underneath, and the sensor 5 can be installed on the filter 26.

It is a top view of FIGS. 13a and 13. The part of the face that touches the chin under the mouth is the filter device 27, which actually fits the curve and eliminates the gap with the chin.

Figure 14, transparency allows the other party to see the movement of the mouth. The transparent mask cover 28 is shaped like, for example, a transparent 3D mask with a rectangular transparent cover attached. The part that comes into contact with the face is made of silicone resin, rubber, etc. to ensure the degree of sealing with the face. The height of the transparent mask cover 28 is about 60 mm for the 3D mask, and it feels like a rectangular box is attached from a position about 40 mm from the contact surface with the face. The thickness of the rectangular box is considered to be about 20-40 mm. This wearer breathes through the filter device 27. The wearer breathes only with the air that has passed through the filter 26.
It is also good to equip this device with a microphone 18 and a speaker with a built-in amplifier 19 to supplement the volume and sound quality of the wearer's vocalization. A display device 21 may be mounted. If the display device 21 at that time is installed near the filter device 27, the mouth of the mask wearer will not be hidden. It is also possible to install a sterilizer 7. The operation of the fan 1 is an auxiliary operation for the exhaled air intake of the mask wearer, but at a minimum, it is possible to operate only for the exhaled air.
The face shield 29 is fixed by the face shield fixture 23, but a hook-and-loop fastener that can be easily removed may be used.
The fixed parts of the filter 26 and the filter device 27 are completely covered with flexible silicone.
The filter device 27 may be installed on the left and right sides of the face.

It is a side view of FIG. 14a and FIG. Since the transparent mask cover device 28 and a part 9 of the transparent mask cover device 28 are integrated and their spaces are connected, it is possible to use a general mask shape as one.

Figure 15, CPU and CPU peripheral circuits and drive circuits are used to signal various inputs to control various devices. When the valve installed in the gap of the photo interrupter 16 opens, the input from the LED of the photo transistor is cut off, and the signal is transmitted to the CPU to judge breathing and control fan 1 and other devices. Similarly, the signal of the sensor 5 also processes the signal as described separately to control the fan 1 and other devices. In this case, the speaker 19 with a built-in amplifier can be driven by the output from the control device 17 even if it does not have a built-in amplifier. Here, these various input / output devices share GND outside the control device 17 and send it to the control device as a single unit. There may be two fans, but in that case, only one wire for the fan is added, and one wire can be connected to GND as well. Furthermore, as mentioned above, when two fans are connected and used to rotate the fan in the forward and reverse directions, the GND line is also common and only two more lines are added.
R1 is the current limiting resistor of the LED of the photo interrupter, and R2 is the pull-up resistor of the phototransistor.
A smartphone may also be installed in the control device 17, which may be used as part of the control device 17 for translation, voice analysis, voice transcribing, and signal processing using an Internet connection. Furthermore, it may have the function of the display device 21.
In the case of control using the USB terminal of a smartphone, the signal reception and control signals of the various devices in this figure are obtained by multiplexing the signal with serial data and using the USB terminal. For example, if you use the USB / I2C (SMBus) conversion module MM-CP2112A, you can control input / output via USB. And especially for sensors, I2C devices can be used, for example, barometric pressure / temperature sensor (with level conversion IC) module MM-TXS03 can also be used. I / O devices can be used even if they are not I2C devices. Applications can be developed with Microsoft Visual Studio. This is also a method for using a smartphone instead of the display device 21 and the control device 17, and it is usual to create and install a dedicated application on the smartphone.
In another method, various devices may be sequentially scanned by the shift register, and if the sensors are used as they are, the signal may be acquired according to the scanning timing. Fans, sterilizers, LEDs, display devices, etc. receive the pulsed signal of the scan and convert it to a certain length, or prepare and drive a circuit that processes the signal and drives it.

Fig. 16, Inexpensive masks that are generally distributed or a part of 3D masks made of transparent material. When the partially transparent mask 31 is worn, the resin net 30 is curled up and wraps the wearer's face like a bowl, or is preformed into a shape like a 3D mask. It's like making a space in the mouth or under the nose, which is sold in the market as a mask bracket or mask frame. In this figure, there is nothing in the center, but even if there is a little skeleton, the mouth can be seen from the other party.
The resin net 30 is for fixing various devices described in the present invention, and further, for preventing the shape of the mask from being deformed by the wind pressure generated by the fans 1 and 33. Therefore, it may be necessary to bond the resin net 30 and the partially transparent mask 31 with, for example, double-sided tape.
Also, in this figure, the fan fixing device 32 has a return on a part of the fan on the outside of the mask, or the mask is pierced with something like a pin that inflates a part, and the female side of it is made and fixed to the resin net 30. There is also a method.
Fan 1 and fan 33 with speaker apply wind pressure to the non-transparent part of the partially transparent mask 31 to make breathing easier.

In FIGS. 17 and 16, the fan is installed outside the mask, but this is an example in which all the devices are installed inside the resin net 30. In this figure, there are gaps on the left and right sides of the partially transparent mask 31 and the resin net 30, but if a mask is installed, the gaps will disappear.
Fan 1 applies wind pressure to the non-transparent part of the partially transparent mask 31 to make breathing easier.

From Fig. 18 and Fig. 16.17, the resin net 30 was eliminated. Install the

fan cases

34 and 34a on a partially transparent mask 31 with tape or adhesive so that there is no air leakage. As a result, the fan case may cover parts other than the transparent part of the mask rather than installing a single fan, and there is also space for installing multiple fans, resulting in stronger fan power and an air filter area. growing.

Fans

34 and 34a assist in breathing to facilitate breathing.
A fan case 34a with a sensor detects respiration and a separately installed control device 17 controls the two fans.
The microphone 18 and the speaker 19 with a built-in amplifier are set or installed in the fan case, respectively, to output the sound of the mask wearer.
