First embodiment
Referring to fig. 1 and 2, the present embodiment provides an air supply device 100, and the air supply device 100 provided in the present embodiment can isolate external air from air on the face of a user, reduce pollution of the external air to air in an air curtain, and improve quality of air inhaled by the user.
In the present embodiment, the air supply device 100 includes: the wearable part 110, the upper cover 120 and the bottom part 130, the upper cover 120, the bottom part 130 and the wearable part 110 are connected to form a distribution cavity 112 for conveying air together, a slow release opening 150 communicated with the distribution cavity 112 is arranged on the bottom part 130 close to the wearable part 110, and a jet opening 140 communicated with the distribution cavity 112 is arranged on the bottom part 130 far away from the wearable part 110;
the jet ports 140 are used to jet an air curtain around the face at a jet wind speed;
the slow release port 150 is used for injecting air for breathing into the air curtain at a slow release wind speed, and the injection wind speed is greater than the slow release wind speed.
In this embodiment, the wearing portion 110 is mainly used to wear the entire air supply device 100 on the head of the user, the slow release opening 150 is disposed near the user, the jet opening 140 is disposed far away from the user, the jet opening 140 forms an air curtain at the jet air speed, the air curtain can isolate the air blown out from the slow release opening 150 from the outside air, so that the user can breathe the breathing air injected from the slow release opening 150, the pollution of the outside air to the air in the air curtain can be reduced, and the quality of the air inhaled by the user can be improved.
In addition, the jet ports 140 form an air curtain for isolating the face of the user from the outside at a large jet wind speed, inject air for breathing of the user into the air curtain at a small slow-release wind speed, form the air curtain at a large jet wind speed, and inject air for breathing at a small slow-release wind speed, so that discomfort of the user caused by the fact that the large wind speed forming the air curtain directly blows to the face of the user can be avoided.
Meanwhile, since the wearing part 110 is generally worn on the head of the user, the air ejected from the ejection port 140 and the air ejected from the slow-release port 150 are both ejected downward, so that a slight positive pressure is formed around the face of the user, and the external air is prevented from going from the bottom 130 of the air curtain to the inside of the air curtain, thereby ensuring the air quality in the air curtain.
In the present embodiment, in order to form a continuous air curtain by the air ejected from the ejection port 140, the ejection air speed is greater than or equal to 2m/s, and the air curtain is more tight as the ejection air speed is higher, so that the inside of the air curtain can be separated from the external environment.
Because the air blown out from the slow release port 150 is mainly used for the user to breathe, if the slow release wind speed is high, the user can not feel good in breathing experience, and therefore the slow release wind speed is low, breeze appears in the air curtain, and the user can breathe conveniently. Thus, the slow release wind speed is less than or equal to 1m/s.
In this embodiment, the air entering the dispensing chamber 112 is purified air that has been filtered, sanitized, etc. multiple times.
In this embodiment, the bottom portion 130 further has a mounting portion 160 protruding thereon, the mounting portion 160 is disposed apart from the wearing portion 110, and the injection port 140 is disposed on the mounting portion 160. The position of the injection port 140 provided in the mounting portion 160 is lower than the position of the slow-release port 150, and the problem that the breathing air in the air curtain leaks from the air curtain in the process that the injection port 140 forms the air curtain at the injection speed can be reduced.
In the present embodiment, the ejection openings 140 are plural, and the distance between the plural ejection openings 140 is less than or equal to 2mm.
The plurality of injection ports 140 are annularly arranged on the side edge of the bottom 130 far away from the wearing portion 110, and the plurality of injection ports 140 are annularly arranged around the face of the user to separate the face of the user from the external environment, so that the external air is prevented from entering the air curtain to pollute the air in the air curtain, and the health and safety of the air for breathing of the user are improved.
Meanwhile, the longer the length of the mounting part 160, the longer the ejection port 140 length, the ejection port 140 may form a slim slit, thereby increasing the ejection speed.
Referring to fig. 3, in the present embodiment, the injection opening 140 has a first end 142 and a second end 144 opposite to each other, the first end 142 is disposed near the distribution cavity 112, and a ventilation area of the first end 142 is larger than a ventilation area of the second end 144.
In the present embodiment, the air ejected from the ejection port 140 and the slow-release port 150 is the air entering the distribution chamber 112, and different wind speeds are realized according to the structures of the ejection port 140 and the slow-release port 150, so that the air supply device 100 can simultaneously eject a large ejection wind speed and a small slow-release wind speed, thereby solving the contradiction between the high wind speed and the low wind speed.
The ventilation area of the first end 142 is larger than the ventilation area of the second end 144, so that the jet opening 140 is considered to be gradually reduced from inside to outside, and after the air in the distribution cavity 112 enters the jet opening 140 from the first end 142, the air is gradually extruded through the gradually reduced passage of the jet opening 140, so that the air not jetted from the second end 144 can form an air curtain at the jet air speed.
In this embodiment, the ejection opening 140 may be a narrow slit with a gradually decreasing diameter from the inside to the outside. The greater the difference between the first end 142 and the second end 144, the greater the velocity of the air curtain ejected from the ejection port 140.
In this embodiment, the width of the first end 142 is greater than or equal to 5mm, and the width of the second end 144 is less than or equal to 1mm.
In the present embodiment, under the condition that the width of the first end 142 is greater than or equal to 5mm and the width of the second end 144 is less than or equal to 1mm, the air from the ejection port 140 may be considered to form an air curtain at an ejection speed of 2m/s under an appropriate pressure.
Referring to fig. 4, in the present embodiment, the slow-release opening 150 has a third end 152 and a fourth end 154 opposite to each other, the third end 152 is disposed near the dispensing chamber 112, and the ventilation area of the third end 152 is smaller than that of the fourth end 154.
The shape of the slow release opening 150 is opposite to that of the injection opening 140, the injection opening 140 is small inside and large outside, the slow release opening 150 is large inside and small outside, and after air in the distribution cavity 112 enters the slow release opening 150 from the third end 152, the pressure of the air entering the slow release opening 150 is gradually reduced due to the gradual increase of the slow release opening 150, and the slow release wind speed is also gradually reduced.
It is easy to understand that the larger the difference between the ventilation area of the third end 152 and the ventilation area of the fourth end 154, the smaller the slow-release wind speed, and in order to ensure that the slow-release wind speed can be as small as possible, it is required that the ventilation area of the third end 152 is as small as possible and the ventilation area of the fourth end 154 is as large as possible. In order to ensure the air quantity in the air curtain, a plurality of slow release openings 150 are arranged, the specific number can be set according to the actual situation,
in this embodiment, the width of the third end 152 is less than or equal to 1mm, and the width of the fourth end 154 is greater than or equal to 2mm.
In the present embodiment, it is considered that, under appropriate pressure conditions, when the width of the third end 152 is less than 1mm and the width of the fourth end 154 is greater than 2mm, the slow-release wind speed in the slow-release opening 150 can be approximately about 1 mm/s.
In this embodiment, the slow release opening 150 is provided with a filter member for filtering air ejected from the slow release opening 150.
In this embodiment, the filter element may be disposed near the third end 152, and may also be disposed near the fourth end 154, and the filter element further plays a role of filtering, so as to prevent impurities entering the distribution cavity 112 from being blown out from the slow release opening 150, which affects the quality of the user's breath, and also plays a role of reducing pressure and releasing pressure.
Referring to fig. 1 and 2, in the present embodiment, the wearing portion 110 or the upper cover 120 is provided with an air inlet 180, and the air inlet 180 is communicated with the distribution cavity 112 for introducing air into the distribution cavity 112.
The air inlet 180 is mainly used for being connected with an air source, so that the filtered, sterilized and the like air enters the distribution cavity 112 and passes through the jet orifice 140 and the slow release orifice 150 to form two kinds of air with different speeds. The air inlet 180 may be connected to a matching air source at any position, that is, the air supply device 100 provided in this embodiment is portable and can be adapted to the matching air source.
In this embodiment, the air supply device 100 further includes an outer edge 170, the outer edge 170 is disposed on the bottom 130 and near the jet opening 140, and the outer edge 170, the upper cover 120, the bottom 130 and the wearing portion 110 may jointly form the dispensing cavity 112.
In summary, in the air supply device 100 provided in this embodiment, the wearing portion 110 is mainly used to wear the entire air supply device 100 on the head of the user, the slow release opening 150 is disposed near the user, the jet opening 140 is disposed away from the user, the jet opening 140 forms an air curtain at the jet air speed, the air curtain can isolate the air blown out from the slow release opening 150 from the outside air, so that the user can breathe the breathing air injected from the slow release opening 150, the pollution of the outside air to the air in the air curtain can be reduced, and the quality of the air inhaled by the user can be improved.
Second embodiment
Referring to fig. 5, the present embodiment provides a method for transporting air for breathing, which is mainly used for the air supply device 100 provided in the first embodiment, and can isolate external air from air on the face of a user, reduce pollution of the external air to air in an air curtain, and improve quality of air inhaled by the user.
For the sake of brief description, the first embodiment may be referred to where this embodiment is not mentioned.
The method for conveying air for breathing provided by the embodiment comprises the following specific steps:
step S100, an air curtain surrounding the face is ejected at an ejection wind speed.
Step S200, injecting air for breathing into the air curtain at slow-release wind speed; wherein the jet wind speed is greater than the slow release wind speed.
In this embodiment, the jet air speed is greater than or equal to 2m/s and the slow release air speed is less than or equal to 1m/s.
In the present embodiment, in order to form a continuous air curtain by the air ejected from the ejection port 140, the ejection air speed is greater than or equal to 2m/s, the pressure of the air curtain is higher as the ejection air speed is higher, and the interior of the air curtain can be separated from the external environment.
Because the air blown out from the slow release port 150 is mainly used for the user to breathe, if the slow release wind speed is high, the user can not feel good in breathing experience, and therefore the slow release wind speed is low, breeze appears in the air curtain, and the user can breathe conveniently. Thus, the slow release wind speed is less than or equal to 1m/s.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
