the driving mechanism 7, the piston 5 reciprocates along the length direction of the branch pipe 4 under the action of the driving mechanism 7;

based on the characteristics, when the air inlet device works, the piston 5 slides reciprocally in the branch pipe 4, when the air inlet device slides to the upper limit position, the air inlet device is higher than the air hole 6, external air can enter the section of pipe cavity below the piston 5 in the branch pipe 4 through the air hole 6, when the piston 5 slides downwards, the air encapsulated in the branch pipe 4 is pressed into the water storage tank 3 until passing through the air hole 6, so that the air enters the water body, finally floats on the water surface and enters the air inlet pipe 2, finally enters the detector 1 for detection, the air is filtered through the water body, compared with the existing filtering mode, the air inlet device directly acts on the air, so that the air is pressed into the air inlet pipe 2 to enter the detector 1, the air inlet effect is better, meanwhile, the filtering effect by means of the water body is better than that of the conventional net interception type, and the detector 1 can be better protected;

the driving mechanism 7 may take various forms, and a reciprocating screw is specifically adopted, as shown in fig. 1, the reciprocating screw is rotatably disposed on the water storage tank 3, the length direction is consistent with the branch pipe 4, a guide block meshed with the reciprocating screw is disposed on the reciprocating screw, and the reciprocating screw is sleeved on the branch pipe 4, so that sliding on the branch pipe 4 is realized, the guide block and the piston 5 in the branch pipe 4 have a magnetic attraction relationship, when the guide block moves, the piston 5 synchronously moves, a driving effect is realized, and specifically, a magnet can be buried in the piston 5 and the guide block, so that magnetic attraction matching is realized, a driving motor is disposed on the outer shell of the water storage tank 3, and the driving motor is started up when the driving motor works, so that the driving motor provides rotary power for the reciprocating screw through a gear assembly.

As shown in fig. 2, the branch pipe 4 and the water storage tank 3 are integrally formed, fig. 2 is an effect diagram when the whole is vertically cut, in some embodiments, the space in the water storage tank 3 is provided with a top 8 and a bottom 9, a main body part of the whole space is located between the top 8 and the bottom 9, namely, a water containing position, the branch pipe 4 is communicated with a position close to the bottom 9 of the water storage tank 3, and the air inlet pipe 2 is communicated with the top 8 of the water storage tank 3, so that when air enters the water storage tank 3, the air directly enters the water bottom, and the whole water is required to pass through when the air floats out of the water, so that the residence time of the air in the water can be prolonged, and the filtering effect is improved.

As shown in fig. 2, in some embodiments, the space in the water storage tank 3 sequentially comprises an air inlet part 10 and a filtering part 11 positioned at one side of the air inlet part 10, the filtering part 11 is positioned at the bottom 9, the air inlet part 10 is provided with a guide surface 12 near the bottom 9, the branch pipe 4 penetrates through the guide surface 12 and is communicated with the air inlet part 10, an inclined angle is formed between the guide surface 12 and the horizontal direction, so that after air enters the air inlet part 10, the air can be better guided to the filtering part 11 under the inclined action of the guide surface 12, and thus enters a water body and floats upwards.

As shown in fig. 2, in some embodiments, the filtering portion 11 is provided with a plurality of baffle plates 13 sequentially from the top 8 to the bottom 9, and the baffle plates are sequentially staggered, so that the residence time of the gas in the water can be further increased.
