the embodiment provides a high flow humidification system, which comprises a humidification instrument, an external oxygen source and a high pressure oxygen noise reduction device 100.
The high-pressure oxygen noise reduction device 100 comprises an oxygen supply assembly 110 and a sound muffling box 120; the oxygen supply assembly 110 comprises an oxygen supply pipe 111, a pressure reducing valve 114 and an electromagnetic valve 115; the pressure reducing valve 114 and the electromagnetic valve 115 are sequentially connected with the oxygen supply pipe 111 along the direction from the air inlet end 112 to the air outlet end 113 of the oxygen supply pipe 111; the inlet end 112 is in communication with an external oxygen source;
the sound deadening box 120 includes a box body 121, an oxygen inlet joint 122, an air inlet joint 123, an air outlet joint, a first sound deadening portion 124, and a second sound deadening portion 125; the oxygen inlet joint 122, the air inlet joint 123 and the air outlet joint are communicated with the box body 121; the oxygen inlet joint 122 is communicated with the air outlet end 113 of the oxygen supply pipe 111, the air outlet joint is used for being communicated with a humidifier, and the air inlet joint 123 is used for being communicated with the outside; the first silencing part 124 and the second silencing part 125 are both accommodated in the box body 121, the first silencing part 124 is positioned at the communication position of the oxygen inlet joint 122 and the box body 121, and the second silencing part 125 is positioned at the communication position of the air inlet joint 123 and the box body 121;
the first silencing part 124 is used for eliminating noise at the communication part of the oxygen inlet joint 122 and the box body 121; the second muffling portion 125 is for muffling noise at the communication of the air intake joint 123 with the case 121.
The air outlet joint of the high-pressure oxygen noise reduction device 100 is connected with a humidifier, and the air inlet joint 123 of the high-pressure oxygen noise reduction device 100 is connected with an external oxygen source.
The working principle of the high-flow humidification system is as follows:
referring to fig. 1-3, in the operation process of the high flow humidification system, high pressure oxygen output from an external oxygen source enters the oxygen supply pipe 111 through the air inlet end 112 of the oxygen supply pipe 111, and sequentially passes through the pressure reducing valve 114 and the electromagnetic valve 115, and then enters the box body 121 through the oxygen inlet joint 122, and meanwhile, air input into the box body 121 through the air inlet joint 123 is mixed with oxygen in the box body 121, and enters the humidification apparatus through the air outlet joint;
in the above process, when oxygen passes through the pressure reducing valve 114 and the electromagnetic valve 115, the pressure of oxygen can be reduced by the pressure reducing valve 114, and the flow rate of oxygen can be adjusted by the electromagnetic valve 115, so that the pressure of oxygen can be further reduced, and thus, the mode of gradually reducing the pressure of oxygen can be adopted, and the generation of loud noise caused by sudden pressure drop of oxygen can be avoided;
secondly, because the oxygen entering the box 121 through the oxygen inlet joint 122 is reduced under the action of the pressure reducing valve 114 and the electromagnetic valve 115, the noise of the oxygen entering the box 121 can be reduced due to the lower pressure when the oxygen is conveyed to the box 121 from the oxygen supply pipe 111;
noise at the communication between the oxygen inlet joint 122 and the casing 121 can be eliminated by the first noise elimination unit 124, and noise at the communication between the air inlet joint 123 and the casing 121 can be eliminated by the second noise elimination unit 125;
in addition, since the oxygen pressure in the box 121 is reduced, the pressure of the mixed gas output to the humidifier can be reduced in such a way, and thus, the humidifier can be prevented from generating large noise in the operation process.
Therefore, the high-flow humidification system can reduce noise generated in the operation process and avoid influence on user experience due to overlarge noise.
Further, referring to fig. 1 to 6, fig. 4 and 5 show the structure of the sound-deadening box in the embodiment of the present invention, and fig. 6 shows the structure of the sound eliminator in the embodiment of the present invention, in the embodiment, the first sound-deadening portion 124 and the second sound-deadening portion 125 function to reduce noise when oxygen and air enter the box body 121.
Therefore, when the first silencing part 124 is provided, the first silencing part 124 may include a silencer 126, and the silencer 126 is accommodated in the box 121 and is communicated with the oxygen inlet joint 122. After oxygen enters the box body 121 from the oxygen inlet joint 122, the oxygen firstly enters the silencer 126, the silencer 126 is integrally connected with the box body 121 in a sealing manner, and the silencer can be in injection molding, so that firm connection and good sealing are ensured. After passing through the silencer 126, the single-strand oxygen is converted into a plurality of small air flows, so that the flow rate of the oxygen can be reduced, and the noise generated when the oxygen flows can be reduced. It should be noted that the silencer 126 may be formed by punching thin-walled stainless steel, through holes 134 are formed in the outer circumferential surface of the silencer 126 in a matrix arrangement for passing oxygen, and the total gas passing area of all the through holes 134 may be 1.5 times the gas passing area of the oxygen inlet joint 122, so that when oxygen passes through the silencer 126, oxygen can be depressurized, and noise generated by the oxygen during depressurization can be absorbed.
In addition, the first sound-deadening portion 124 may further include a microporous filter cloth 127, and the microporous filter cloth 127 is wrapped around the outer circumferential surface of the muffler 126. Under the coating effect of the microporous filter cotton 127, a small airflow output by the silencer 126 enters the microporous filter cotton 127 and is divided into smaller airflows, so that the flow velocity of oxygen can be further reduced, and the noise generated when the oxygen flows can be further reduced.
Therefore, the noise generated when oxygen is conveyed into the box 121 through the oxygen inlet joint 122 can be reduced by the silencer 126, and the noise generated when oxygen enters the box 121 through the silencer 126 can be reduced by coating the outer peripheral surface of the silencer 126 with the microporous filter cloth 127, so that the noise generated when oxygen is conveyed into the box 121 through the oxygen inlet joint 122 can be reduced.
And when the first muffling portion 124 is provided, the second muffling portion 125 may include nano muffling cotton 128 disposed at a position where the air intake joint 123 communicates with the case 121. By the arrangement of the nano silencing cotton 128, the noise generated when air enters the box body 121 from the air inlet joint 123 can be reduced.
Further, in order to guide the air entering the interior of the housing 121 through the air inlet joint to mix with the oxygen delivered into the housing 121 through the oxygen inlet joint 122, the sound muffling box 120 further includes a flow guide plate 129 disposed in the housing 121, wherein the flow guide plate 129 is connected to the inner wall of the housing 121 and defines a flow guide channel together with the inner wall of the housing 121, and the flow guide channel is used for guiding the air entering the sound muffling box 120 through the air inlet joint 123 to move towards the direction close to the first sound muffling portion 124.
In order to prevent noise generated when oxygen is delivered into the box body 121 through the oxygen inlet joint 122 from being transmitted out through the air inlet joint 123, the sound muffling box 120 further comprises a flow guide rib 131, and the flow guide rib 131 is accommodated in the flow guide channel and connected with the flow guide plate 129; the air guide rib 131 is inclined in a direction approaching the first muffling portion 124. Through the setting of water conservancy diversion muscle 131, can block the outside transmission of noise, and then can reduce the noise that spreads through air inlet joint 123. Also in this embodiment, the second sound-deadening portion 125 may include a plurality of flow-guiding ribs 131, and the plurality of flow-guiding ribs 131 are sequentially disposed at intervals along the extending direction of the flow-guiding passage.
Further, referring to fig. 1-7, fig. 7 shows a structure of a connecting pipe in an embodiment of the present invention, in this embodiment, in order to reduce the difficulty of connection when connecting the oxygen supply pipe 111 and the box 121, the high pressure oxygen noise reduction device 100 further includes a connecting pipe 132, and two ends of the connecting pipe 132 are respectively connected to the air outlet end 113 of the oxygen supply pipe 111 and the oxygen inlet joint 122. In addition, in order to improve the sealing performance between the air outlet end 113 of the oxygen supply pipe 111 and the oxygen inlet joint 122, the two ends of the connecting pipe 132, which are connected to the air outlet end 113 of the oxygen supply pipe 111 and the oxygen inlet joint 122, are provided with silica gel sleeves 133.
In summary, referring to fig. 1-7, the high flow humidification system is in operation:
through the treatment of the oxygen supply assembly 110 and the sound muffling box 120, the high-pressure oxygen output by an external oxygen source can be stepped, stepped and stepped, and the pressure reduction process can be divided into four stages, specifically, the first stage is that the high-pressure oxygen is reduced in pressure through a pressure reducing valve 114, the second stage is that the high-pressure oxygen is reduced in pressure through an electromagnetic valve 115, the third stage is that the high-pressure oxygen is reduced in pressure through a silencer 126, and the fourth stage is that the high-pressure oxygen is reduced in pressure through the silencer 126 to the cavity of the sound muffling box 120;
and the absorption of pressure release noise can also be divided into four stages, the first stage is the absorption of noise by the pipe wall of the silencer 126, the second stage is the absorption of noise by the microporous filter cotton 127, the third stage is the attenuation, reflection and absorption of noise by the diversion ribs 131, and the fourth stage is the absorption of noise by the nano silencing cotton 128.
Therefore, the high-flow humidification system can avoid generating larger noise in the operation process through the mutual coordination of the pressure reduction and noise reduction processes.
The above description is only for the specific embodiments 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.
