By setting the first connecting piece 60, a sealed installation environment is provided for the balancing component 30. The connection setting of the first pipeline 410 and the second pipeline 420 with the first connecting piece 60 improves the connection stability and air tightness of the balancing component 30 with the first adsorption barrel 10 and the second adsorption barrel 20 respectively, thereby improving the gas transportation efficiency.

[0035] The first valve body 310 and the second valve body 320 provided in this embodiment have simple structures and are easy to install and connect, and can easily achieve the purpose of rapid nitrogen discharge.

[0036] As a preferred solution of this embodiment, refer to Figure 3 The aperture of the second vent 302 is larger than the aperture of the third vent 303 , and the aperture of the fifth vent 305 is larger than the aperture of the sixth vent 306 .

[0037] The purpose of setting the aperture of the second vent 302 larger than the aperture of the third vent 303 is that the flow rate of the oxygen entering the first valve body 310 through the second vent 302 into the oxygen storage tank 50 is greater than the flow rate entering the second valve body 320 through the third vent 303. Therefore, it can be achieved without affecting the first adsorption barrel 10 to prepare oxygen for users, and the purpose of promoting nitrogen discharge can be achieved. Similarly, the purpose of setting the aperture of the fifth vent 305 larger than the aperture of the sixth vent 306 is that the flow rate of the oxygen entering the second valve body 320 through the fifth vent 305 into the oxygen storage tank 50 is greater than the flow rate entering the first valve body 310 through the sixth vent 306. Therefore, it can be achieved without affecting the second adsorption barrel 20 to prepare oxygen for users, and the purpose of promoting nitrogen discharge can be achieved.

[0038] The apertures of the second vent 302, the third vent 303, the fifth vent 305 and the sixth vent 306 are not specifically limited and can be adjusted according to external factors such as the size of the adsorption barrel and the user's oxygen consumption, and are not specifically limited here.

[0039] As a preferred solution of this embodiment, refer to Figure 1 and Figure 4 The oxygen production component also includes: an oxygen storage tank 50 and a second connecting piece 70, the second connecting piece 70 is arranged on the side of the shell 611 away from the first connecting pipe 61; a first opening 601 and a second opening 602 are formed on the side of the shell 611 close to the second connecting piece 70, the first opening 601 is communicated with the second vent 302, and the second opening 602 is communicated with the fifth vent 305; a third valve body 610 is arranged on the side of the shell 611 close to the second connecting piece 70, and the third valve body 610 is used to control the opening and closing of the first opening 601 and the second opening 602, so as to connect or disconnect the first connecting piece 60 and the second connecting piece 70; the end of the second connecting piece 70 away from the first connecting piece 60 is connected to the oxygen storage tank 50.

[0040] Among them, the second connecting piece 70 is configured to connect the first connecting piece 60 and the oxygen storage tank 50 according to actual needs, and is used to transport the oxygen output from the second air vent 302 or the fifth air vent 305 in the first connecting piece 60 to the oxygen storage tank 50, and has the advantages of strong connection air tightness and high integration. When the first adsorption barrel 10 is producing oxygen, oxygen enters the first valve body 310 in the first connecting piece 60 through the first pipeline 410 in sequence. At this time, the airflow impacts the third valve body 610 to control the opening of the first opening 601, so that oxygen can enter the oxygen storage tank 50 through the second connecting piece 70. Similarly, when the second adsorption barrel 20 is producing oxygen, oxygen enters the second valve body 320 in the first connecting piece 60 through the second pipeline 420 in sequence. At this time, the airflow impacts the third valve body 610 and then controls the opening of the second opening 602, so that oxygen can enter the oxygen storage tank 50 through the second connecting piece 70.

[0041] The oxygen passing through the first opening 601 and the second opening 602 is input into the oxygen storage tank 50 through the second connecting piece 70 .

The third valve body 610 includes a first valve plate 6101, a fixed portion 6103 and a second valve plate 6102 connected in sequence. The fixed portion 6103 is provided on the fixed boss 620. The first valve plate 6101 can movably cover the first opening 601, and the second valve plate 6102 can movably cover the second opening 602.

[0043] Among them, the setting of the fixed boss 620 can provide a stable installation platform for the third valve body 610. Specifically, the third valve body 610 includes a first valve plate 6101, a fixed portion 6103 and a second valve plate 6102 connected in sequence.

During operation, when the first adsorption barrel 10 is working, after the oxygen enters the first valve body 310 through the first pipeline 410 in sequence, the airflow impacts the first valve plate 6101 along the first vent 301 and the second vent 302, so that the first valve plate 6101 is separated from the first opening 601, thereby achieving The purpose of opening the first opening 601 is, of course, that when the first adsorption barrel 10 is not producing oxygen, the first valve body 310 always covers the first opening 601, so that the first opening 601 is in a closed state, which can prevent the gas in the oxygen storage tank 50 from flowing back; similarly, when the second adsorption barrel 20 is working, oxygen enters the second valve body 320 through the second pipeline 420 in turn, and the air flow passes through the fourth air vent 304 and the fifth air vent 305 and then impacts the second valve plate 6102, so that the second valve plate 6102 is separated from the second opening 602, thereby achieving the purpose of opening the second opening 602. Of course, when the second adsorption barrel 20 is not producing oxygen, the second valve body 320 always covers the second opening 602, so that the second opening 602 is in a closed state.

[0046] The cooperation of the first protrusion 630 and the second protrusion 640 provides a stable setting environment for the first valve disc 6101. When the first opening 601 is opened, when the airflow passing through the first opening 601 is too large, it can prevent the first valve disc 6101 from being separated from the first opening 601 by too large a distance and unable to be reset, or the first valve disc 6101 cannot cover the first opening 601 after being reset. Similarly, the cooperation of the first protrusion 630 and the third protrusion 650 provides a stable setting environment for the second valve disc 6102. When the second opening 602 is opened, when the airflow passing through the second opening 602 is too large, it can prevent the second valve disc 6102 from being separated from the second opening 602 by too large a distance and unable to be reset, or the second opening 602 cannot cover the second opening 602 after being reset.
