[0033] The following is combined with Figure 1-6This application is described in further detail.

[0034] The embodiment of the present application discloses a harmful gas detection device, including a detection box 1, which is divided into an air intake part 2 and an air outlet part 3. The air intake part 2 is provided with an air inlet 4, the left side of the detection box 1 is fixedly connected to the air inlet 4, the left side of the air inlet 4 is fixedly connected to an air intake hood 5, the interior of the air intake hood 5 is fixedly connected to a purification mechanism 6, the interior of the detection box 1 is fixedly connected to a connecting mechanism 7, the air outlet part 3 is provided with a baffle 8, the connecting mechanism 7 is fixedly connected to the baffle 8, one side of the baffle 8 is fixedly connected to a gasket 9, the gasket 9 is in contact with the detection box 1, and one side of the baffle 8 is fixedly connected to an air outlet 10. Gas enters through the air intake hood 5, and the air is purified by the purification mechanism 6. When the activated carbon filter 65 needs to be replaced, the replacement of the activated carbon filter 65 is more convenient through the connecting mechanism 7.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The purification mechanism 6 includes a filter 61, a partition 62, a grid 63, a connecting block 64, an activated carbon filter 65 and a disinfection component 66. The air intake hood 5 is fixedly connected to the filter 61, one side of the filter 61 is fixedly connected to the partition 62, both ends of the partition 62 are fixedly connected to the air intake hood 5, one side of the partition 62 is fixedly connected to the grid 63, the grid 63 is fixedly connected to the inside of the air intake hood 5, the connecting block 64 is fixedly connected to the inside of the detection box 1, the inner side of the connecting block 64 is fixedly connected to the activated carbon filter 65, and the disinfection component 66 is fixedly connected to the right side of the inside of the detection box 1. More specifically, during use, external gas is drawn in. When the air passes through the filter 61, the filter 61 isolates the particles and dust in the air, and then passes through the desiccant. The desiccant adsorbs the water molecules in the air to protect the electrical equipment inside the detection box 1. Then the air passes through the activated carbon filter 65. The micropores of the activated carbon filter 65 can adsorb low molecular weight organic matter, including formaldehyde, thereby purifying the air.

[0036] Reference Figure 1 ,and Figure 5The disinfection component 66 includes a disinfectant box 661, a booster pump 662, an atomizing nozzle 663 and a collection box 664. The upper interior of the detection box 1 is fixedly connected to the disinfectant box 661, the booster pump 662 is arranged on the upper interior side of the detection box 1, the atomizing nozzle 663 is arranged at the output end of the booster pump 662, and the collection box 664 is slidably connected to the bottom interior of the detection box 1. More specifically, during the purification process of the equipment, the gas enters the disinfection area after being purified once through the activated carbon filter 65. The disinfectant is sprayed by the atomizing nozzle 663 to perform secondary disinfection on the gas, thereby improving the purification effect. The disinfectant flows with the air and will not affect the electrical equipment inside the detection box 1. At the same time, the disinfectant not carried away by the airflow will flow into the collection box 664 for easy collection.

[0037] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism 7 includes a limit plate 71, an insert block 72, a rebound component 73 and a rotating component 74. The interior of the detection box 1 is fixedly connected to the limit plate 71, one side of the limit plate 71 is in contact with the connecting block 64, the interiors of the limit plate 71 and the connecting block 64 are both slidably connected to the insert block 72, the interior of the detection box 1 is fixedly connected to the rebound component 73, and the front side of the detection box 1 is fixedly connected to the rotating component 74. More specifically, when the activated carbon filter 65 needs to be replaced, the insert block 72 is moved away from the connecting block 64. Under the action of force, the insert block 72 squeezes the rebound component 73. When the insert block 72 is displaced to disengage from the rebound component 73, the connecting block 64 can be moved away from the limit plate 71 to remove the activated carbon filter 65, so as to facilitate its replacement.

[0038] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The spring 733 is fixedly connected to the inner side of the detection box 1 and the detection box 1 is fixedly connected to the detection box 1. The spring 733 is mounted on the inner side of the detection box 1 and the detection box 1 is fixedly connected to the detection box 1. The detection box 1 is fixedly connected to ...

[0039] Reference Figure 4 and Figure 5A pull ring is provided on one side of the plug block 72. More specifically, during the process of replacing the activated carbon filter 65, the user can pull the pull ring to cause the plug block 72 to move, which makes it easier for the user to apply pulling force to the plug block 72.

[0040] Reference Figure 1 and Figure 5 The rotating assembly 74 includes a support block 741 and a connecting plate 742. The support block 741 is fixedly connected to the front side of the detection box 1. The support block 741 is hinged to the connecting plate 742. More specifically, when replacing the activated carbon filter 65, it is necessary to rotate the baffle door 8 to a suitable position, and then remove the activated carbon filter 65 by moving the pull ring to replace it.

[0041] Working principle: When in use, air is drawn in from the air inlet hood 5. When the external gas passes through the filter 61, the filter 61 isolates the particles and dust in the air. Then the gas passes through the desiccant, which adsorbs the water molecules in the air, thereby protecting the electrical equipment inside the detection box 1. Then the air passes through the gas sensor for detection. After the detection, the air passes through the activated carbon filter 65. The micropores of the activated carbon filter 65 can adsorb low molecular weight organic matter, including formaldehyde, thereby purifying the air. After the gas passes through the activated carbon filter 65 for one purification, it enters the disinfection area, and the disinfectant is sprayed on the gas through the atomizing nozzle 663. The disinfection is performed twice to improve the purification effect. The disinfectant flows to the outside with the air and will not affect the electrical equipment inside the detection box 1. At the same time, the disinfectant that is not carried away by the airflow will flow into the collection box 664 for easy collection. When the activated carbon filter 65 needs to be replaced, the baffle 8 is rotated to a suitable position, and then the pull ring is pulled so that the pull ring drives the plug block 72 to move. Under the action of the pulling force, the plug block 72 squeezes the plug rod 731, and the plug rod 731 compresses the spring 733 and moves in the direction of the sleeve 732. When the plug rod 731 moves to disengage from the plug block 72, the connecting block 64 can be moved away from the limiting plate 71 to remove the activated carbon filter 65 for replacement.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
