[0038] In this embodiment, an air jet 5 is fixedly installed at the front near the center of one end of the box body 1, and an air pipe is connected to the air jet 5 and one end of the round tube 4. An oil filling port 6 and an emulsification chamber 8 are fixedly installed on the outside of the round tube 4 near one end and near the middle, respectively. An oil outlet 7 and two water outlets 9 are fixedly installed at the front near one end of the top and near the middle of the top of the box body 1, and water pipes are connected between the oil filling port 6 and the oil outlet 7 and between the emulsification chamber 8 and the water outlet 9. A water tank 10 is fixedly installed at the front near the center of the bottom.

[0040] It should be noted that the utility model is a water emulsification device for a filter test system. When in use, the operator first connects the oil filling port 6 and the emulsification chamber 8 to the oil outlet 7 and the water outlet 9 respectively through water pipes, and connects one end of the round tube 4 to the air jet 5 through an air pipe, and turns on the control switch on the box 1. Under the impetus of the gas from the air jet 5, the oil in the oil outlet 7 and the water in the emulsification chamber 8 are mixed and emulsified, and leave from the discharge pipe 28 under the continuous impetus of the gas;

[0041] When the gas enters the water outlet chamber 12, the sliding plate 15 is pushed first, and then the sliding plate 15 is fixed under the restriction of the limit groove 14, and the baffle 17 closes the through groove 16, so that the gas can smoothly pass through the air hole 18 and continue to move in the round tube 4. When the emulsion is pushed into the water inlet chamber 19 by the gas, the block 23 will be squeezed to fit with the water inlet 20 to prevent the emulsion from entering the water inlet 20, so that the emulsion enters the discharge port 21 and squeezes and pushes the sealing block 29. At this time, the emulsion will push the sealing block 29 to move and compress the spring, so that a gap is generated between the sealing block 29 and the discharge port 21, which is convenient for the emulsion to enter the discharge pipe 28;

[0042] After the emulsification operation is completed, the operator injects clean water into the discharge port 21. At this time, the clean water will pass through the disc 24 and contact the block 23, and squeeze the block 23 to compress the blocking spring, so that the clean water can smoothly enter the water inlet chamber 19 and continue to flow into the water outlet chamber 12. At this time, the sliding plate 15 will fit with the fixed plate 13 under the action of the limit spring. At this time, the through groove 16 is in an open state, and the clean water can smoothly pass through the through groove 16 into the water tank 10, thereby completing the cleaning work of the entire device.
