Benzene is the simplest aromatic hydrocarbon, insoluble in water, soluble in organic solvents, and can itself be used as an organic solvent. Among them, the device for collecting benzene detection samples in the air is a collection device, which is convenient for later detection of the collected benzene.
[0003] At present, when some indoor air benzene collection devices are in use, some collection devices have poor airtightness, resulting in the air during the collection process being interfered by external factors, and data errors are likely to occur during later detection. At the same time, when some collection devices collect benzene in the air, they cannot effectively capture the benzene components in the air within a short time, which is not conducive to the later collection and detection of benzene. Therefore, there are certain limitations. Content of the Utility Model

In the utility model, when the vacuum pump exhausts air through the exhaust pipe and then enters the interior of the water tank through the connected anti-backflow pipe, one end of the air inlet channel is higher than the water surface to prevent water from flowing back into the interior of the vacuum pump. Since the benzene in the air is insoluble in water, when the concentration is high, it forms a layer with water. At this time, the benzene in the air is above the water. Then, by opening the valve on the surface of the drain pipe and connecting it to the surface of the water tank through the drain pipe, the water at the bottom of the water tank is discharged, thereby completing the extraction of the remaining benzene in the water tank. At the same time, the operation is simple and quick, which is convenient for the later detection of benzene. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, when in use, the roller 101 at the bottom of the collection box 1 is moved to the area where collection is required, and the top plate 104 inside the mounting groove 103 is opened, water is injected into the water tank 204, and then the top plate 104 is closed, so that the sealing gasket 105 on the surface of the top plate 104 is embedded in the inner wall of the water tank 204, thereby sealing the water tank 204. When the power supply of the vacuum pump 2 is connected to work, at this time, it is necessary to use a person to carry a handheld board 110 to make the baffle 109 slide along the inside of the slide rail 106 to separate from the surface of the suction pipe 201, thereby driving the suction pipe 201 to perform suction work inside the air inlet 102. When the suction is completed, the two ends of the spring 108 are connected to the surfaces of the mounting groove 2 107 and the baffle 109, so that the baffle 109 is reset, thereby completing the sealing work, thereby preventing the collected gas from being disturbed by external factors and affecting the later measurement results, thereby improving the accuracy.
[0036] In embodiment 2, a baffle 109 is fixedly mounted on the surface of one end of the spring 108 away from the second mounting groove 107, and one side surface of the baffle 109 is movably connected to the surface of the suction pipe 201, a sealing gasket 105 is fixedly mounted on the surface of the side of the top plate 104 close to the roller 101, a hand plate 110 is fixedly mounted on the surface of the baffle 109 away from the collection box 1, an exhaust pipe 202 is fixedly mounted on the surface of one side of the vacuum pump 2, and an anti-backflow pipe 203 is fixedly mounted on the surface of one side of the exhaust pipe 202, a water tank 204 is fixedly mounted on the inner wall of the collection box 1, and the sealing gasket 105 is movably embedded in the surface of the water tank 204, an air inlet channel 205 is opened on the surface of one side of the water tank 204, and one side surface of the air inlet channel 205 is fixedly connected to the surface of the anti-backflow pipe 203, a drain pipe 206 is fixedly mounted on the surface of the water tank 204 away from the air inlet channel 205, and a valve 207 is provided on the surface of the drain pipe 206.
[0037] In this embodiment, when the vacuum pump 2 exhausts air through the exhaust pipe 202, it enters the interior of the water tank 204 through the connected anti-backflow pipe 203, and one end of the air inlet channel 205 is higher than the water surface to prevent water from flowing back into the interior of the vacuum pump 2. Since the benzene in the air is insoluble in water, when the concentration is high, it forms a layer with water. At this time, the benzene in the air is above the water. Then, by opening the valve 207 on the surface of the drain pipe 206, the drain pipe 206 is connected to the surface of the water tank 204, so that the water at the bottom layer inside the water tank 204 is discharged, thereby completing the extraction of the remaining benzene inside the water tank 204. At the same time, the operation is simple and quick, which is convenient for the subsequent detection of benzene.
[0038] Working principle: When in use, the roller 101 at the bottom of the collection box 1 is moved to the area where collection is required, and the top plate 104 inside the installation slot 103 is opened, water is injected into the water tank 204, and then the top plate 104 is closed, so that the sealing gasket 105 on the surface of the top plate 104 is embedded in the inner wall of the water tank 204, thereby sealing the water tank 204. When the power supply of the vacuum pump 2 is connected to work, at this time, it is necessary to use a person to carry a handheld board 110 to slide the baffle 109 along the inside of the slide rail 106 to separate from the surface of the suction pipe 201, thereby driving the suction pipe 201 to perform suction work inside the air inlet 102. When the suction is completed, the two ends of the spring 108 are connected to the surface of the installation slot 2 107 and the baffle 109, so that the baffle 109 is closed. In position, the sealing work is completed, so as to prevent the collected gas from being disturbed by external factors and affecting the later measurement results, thereby improving the accuracy. At the same time, when the vacuum pump 2 exhausts through the exhaust pipe 202, it enters the interior of the water tank 204 through the anti-backflow pipe 203 connected to the right, and one end of the air inlet channel 205 is higher than the water surface to prevent water from flowing back into the interior of the vacuum pump 2. Since the benzene in the air is insoluble in water, when the concentration is high, it forms a layer with water. At this time, the benzene in the air is above the water, and then by opening the valve 207 on the surface of the drain pipe 206, the drain pipe 206 is connected to the surface of the water tank 204, so as to discharge the water at the bottom layer inside the water tank 204, thereby completing the extraction of the remaining benzene inside the water tank 204. At the same time, the operation is simple and quick, which is convenient for the later detection of benzene.
