Description

Technical Field

[0001] The utility model relates to the field of environmental detection, in particular to a portable detector for environmental detection. Background Art

[0002] Environmental testing includes land testing, air testing, water quality testing, noise testing, etc. When performing air testing, ozone in the air can be tested with an ozone detector, so that the ozone content in the air can be known. The ozone detector is small and portable, so it is very suitable for indoor and outdoor testing.

[0003] However, existing portable detectors have certain drawbacks. The ozone content extracted by the ozone detector is different each time it is used. When the air is extracted, oxygen will continuously enter the air pump. The air inside and outside the gas inlet cannot be isolated, which leads to a large error in the ozone content in the air each time, affecting the accuracy of the ozone measurement data. Utility Model Content

[0004] The main purpose of the utility model is to provide a portable detector for environmental detection, which can effectively solve the technical problems raised in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, a portable detector for environmental detection includes an ozone detector 1, a gas inlet 2, and an air pump 3 arranged at the top of the ozone detector 1. A closed structure 4 is arranged inside the ozone detector 1 and located at the gas inlet 2. The closed structure 4 includes a fixed cylinder 41, which is connected to the internal thread of the gas inlet 2. A first fixed ring 42 is welded to one end of the interior of the fixed cylinder 41. A first rotating piece 43 is arranged on the surface of the first fixed ring 42 and close to the inner side of the fixed cylinder 41, and the first rotating piece 43 is movably connected to the first fixed ring 42. An air vent 45 is opened on the side wall of the fixed cylinder 41 to prevent gas from entering the air pump 3 when gas is not collected. The first rotating piece 43 is opened when the air pump 3 absorbs air to ensure that the air is normally detected by the ozone detector 1.

[0022] In this embodiment, a pin is provided at the top of the first rotating piece 43, and the first rotating piece 43 is movably connected to the first fixed ring 42 through the pin, and the first rotating piece 43 covers the middle of the first fixed ring 42. The first rotating piece 43 can be opened when inhaling gas, and the first rotating piece 43 can be closed when the fixed cylinder 41 and the suction end of the air pump 3 are filled with gas.

[0023] In this embodiment, magnetic blocks 44 are provided at the places where the first rotating piece 43 and the first fixed ring 42 are in contact, and the first fixed ring 42 is attracted to the first rotating piece 43 through the magnetic blocks 44, so that the first rotating piece 43 and the first fixed ring 42 can be attracted to each other when not in use.

[0024] In this embodiment, an anti-overflow structure 5 is provided inside the fixed cylinder 41, and the anti-overflow structure 5 includes a second fixed ring 51, which is welded to one end of the inside of the fixed cylinder 41, and a second rotating piece 52 is provided on the surface of the second fixed ring 51 and close to the inner side of the fixed cylinder 41. The second rotating piece 52 is movably connected to the second fixed ring 51, and a telescopic spring 53 is provided inside the fixed cylinder 41 and between the second rotating piece 52 and the first rotating piece 43. After the air pump 3 continuously draws air, the interior of the fixed cylinder 41 will be filled, so that the first rotating piece 43 and the second rotating piece 52 can be closed to prevent the air from continuing to be sucked into the interior of the ozone detector 1, so that the volume of air drawn each time can be ensured to be the same, thereby improving the accuracy of the measured data.

[0025] In this embodiment, one end of the telescopic spring 53 is connected to the second rotating piece 52, and the other end of the telescopic spring 53 is connected to the first rotating piece 43. When the air force drawn by the air pump 3 is greater than the magnetism of the magnetic suction block 44, the first rotating piece 43 of the first fixed ring 42 can be opened, and the second rotating piece 52 of the second fixed ring 51 can be pushed, so that the suction end of the air pump 3 and the interior of the fixed cylinder 41 are filled with gas.

[0026] In this embodiment, the interior of the fixed cylinder 41, the air vent 45 and the air suction end of the air pump 3 are interconnected, and the second rotating piece 52 and the first rotating piece 43 are symmetrically arranged inside the fixed cylinder 41 to measure the ozone content of the gas in the space.

[0027] It should be noted that when it is necessary to detect the ozone gas in the environment, the staff can hold the ozone detector 1 and turn on the air pump 3 to allow the gas to enter the inside of the gas inlet 2. The ozone detector 1 can be used to detect the inhaled air to know the ozone concentration in the environment. During the extraction of oxygen, the air pump 3 extracts oxygen, which will drive the first rotating piece 43 of the first fixed ring 42 to flip, so that air enters the inside of the fixed cylinder 41 and the suction end of the air pump 3. When the air in the space becomes more and more, the air pressure in the space will increase, so that the first rotating piece 43 and the second rotating piece 52 are closed, thereby ensuring that the telescopic spring 5 3 ensures that the first rotating piece 43 and the second rotating piece 52 are in close contact, ensures that the air content of the space is constant, and ensures that the content absorbed by the space each time is relatively stable, so that the ozone in the air can be measured more accurately. After the ozone is measured, the detected air is discharged through the air pump 3. When the air pump 3 does not need to extract air, the first rotating piece 43 can be sucked together by the magnetic suction block 44, and the telescopic spring 53 between the second rotating piece 52 and the first rotating piece 43 ensures that the second rotating piece 52 and the first rotating piece 43 are closed to prevent the air from continuing to be sucked into the interior of the ozone detector 1, which can ensure that the volume of air extracted each time is the same, thereby improving the accuracy of the measured data.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
