When the second piston 72 moves up, the external gas enters between the second piston 72 and the bottom of the piston cylinder 71 through the air inlet groove 711 and the second one-way valve 721. When the second piston 72 moves down, the gas between the second piston 72 and the bottom of the piston cylinder 71 is pressed into the pipeline 75 through the third one-way valve 713 in the air outlet hole 712, and enters the air passage 31 through the pipeline 75 and the air inlet hole 741.

[0044] In some other embodiments, the gas source may be directly set as a gas tank or an air pump.

When the stirring motor 2 is working, the first bevel gear 732 can be driven to rotate by the second bevel gear 21, thereby driving the cam 731 to rotate, and the cam 731 can cooperate with the third spring 734 during the rotation process to realize the up and down movement of the second piston 72. A track groove is formed on the cam 731 , and the top of the driving rod 733 is pressed tightly against the track groove.

[0048] When the surfactant production equipment of the present invention is stirred:

[0049] The stirring motor 2 is controlled to work, and the stirring motor 2 drives the stirring shaft 3 to rotate. When the stirring shaft 3 rotates, it drives the stirring rod 41 to stir the liquid in the cylinder 1.

[0050] During the operation of the stirring motor 2 , the first bevel gear 732 is driven to rotate by the second bevel gear 21 , thereby driving the cam 731 to rotate. During the rotation of the cam 731 , the cam cooperates with the third spring 734 to realize the up and down movement of the second piston 72 .

[0051] When the second piston 72 moves upward, external air enters between the second piston 72 and the bottom of the piston cylinder 71 through the air inlet groove 711 and the second one-way valve 721 .

[0053] The gas in the airway 31 enters the second through hole 522 through the second air hole 32 and the first air hole 511, increasing the pressure in the second through hole 522 and forcing the first piston 53 to slide in the second through hole 522. After squeezing the first spring 531, the first piston 53 pushes the locking rod 62 to move toward the inner wall of the cylinder 1 until the locking rod 62 is pressed against the inner wall of the cylinder 1.

[0054] After the locking rod 62 is pressed against the inner wall of the cylinder 1 , the pressure continues to increase, and the second piston 72 compresses the second spring 622 until the second through hole 522 is connected to the first one-way valve 523 , and the gas enters the cylinder 1 through the first one-way valve 523 to disturb the liquid in the cylinder 1 .

[0055] When the stirring mechanism needs to be taken out, the pressure in the second through hole 522 can be reduced by the pressure relief valve, so that the stirring mechanism can be taken out from the cylinder 1.
