[0026] Furthermore, a fan 210 is fixedly connected to the inside of the fan frame 22, a filter frame 24 is movably connected to the outer surface of the activated carbon frame 23, a protective component 3 is provided on the outer surface of the filter frame 24, an air inlet 25 is provided inside the activated carbon frame 23, the protective component 3 includes a positioning member 31, the positioning member 31 is fixedly connected to the side surface of the filter frame 24 in four groups, a guide groove 32 is provided on the outer surface of the positioning member 31, a sliding block 34 is slidably connected to the outer surface of the positioning member 31, and a protective plate 33 is fixedly connected to the inner surface of the sliding block 34. Through the setting of the guide groove 32, when the protective plate 33 is sleeved on the surface of the filter frame 24, it can effectively play a guiding role, thereby effectively making the device smoother when in use.

[0027] Furthermore, the guide groove 32 is opened inside the side of the positioning member 31 away from the filter frame 24, and the protective plate 33 is slidably connected inside the guide groove 32. Through the setting of the sliding block 34, when the sliding block 34 is sleeved on the surface of the filter frame 24, the sliding block 34 can be sleeved along the positioning member 31 along the surface of the activated carbon frame 23, the fan frame 22 and the fixed ring 21, thereby effectively blocking the gaps of the movable connections between the filter frame 24 and the activated carbon frame 23, the activated carbon frame 23 and the fan frame 22, and the fan frame 22 and the fixed ring 21, thereby preventing impurities from entering the interior of the detection shell 11 through the gaps.

[0028] Furthermore, the fixing ring 21 is fixedly connected to the side surface of the detection shell 11, the side surface of the detection shell 11 is provided with an exhaust pipe 12, the fan frame 22 is sleeved on the side of the fixing ring 21 away from the detection shell 11, the activated carbon frame 23 is sleeved on the side of the fan frame 22 away from the fixing ring 21, and the filter frame 24 is sleeved on the side of the activated carbon frame 23 away from the fan frame 22. Through the setting of the activated carbon frame 23 and the filter frame 24, a filter can be placed inside the filter frame 24, and activated carbon can be placed inside the activated carbon frame 23. Impurities in the exhaust gas are filtered through the filter frame 24 and the activated carbon frame 23, so that the concentration of the organic exhaust gas meets the detection concentration requirement, making the data more accurate.

[0029] Furthermore, the fixed seat 26 is fixedly connected to the side surface of the activated carbon frame 23 away from the fan frame 22, and the connecting rod 27 is connected to the inside of the movable part 28. Through the setting of the movable part 28, the movable part 28 can be slidably connected between the fixed part 29 and the fixed seat 26. When the filter frame 24 is sleeved on the outer surface of the activated carbon frame 23, the filter frame 24 is pressed against the activated carbon frame 23 again. Under the action of the movable part 28, the limit of the filter frame 24 by the activated carbon frame 23 can be released.

[0030] Furthermore, the movable part 28 is sleeved on the outer surface of the connecting rod 27, and the fixed part 29 is fixedly connected to the end surface of the connecting rod 27 away from the fixed seat 26. Through the setting of the fixed part 29, when the filter frame 24 is pressed on the outer surface of the activated carbon frame 23, the clamping rod 213 will be clamped between the fixed part 29 and the movable part 28, thereby playing a role of limiting and fixing. The fixed seats 26 are arranged in multiple groups on the fixed ring 21, the fan frame 22, and the side surface of the activated carbon frame 23 away from the detection shell 11.

[0031] Furthermore, the limiting member 211 is provided inside the side of the fan frame 22 facing the fixing ring 21, the fixing member 29 is sleeved inside the limiting member 211, and the clamping rod 213 is movably connected inside the limiting member 211. Through the setting of the limiting member 211, a press connection between the fan frame 22 and the fixing ring 21 can be achieved, so that the fan frame 22 and the fixing ring 21 can be quickly disassembled, installed and used together.

[0032] Furthermore, the spring 214 is sleeved on the side surface of the clamping rod 213 that moves inside the limiting member 211, one end of the spring 214 is fixedly connected to the outward end surface of the clamping rod 213, the other end of the spring 214 is fixedly connected to the inner wall of the movable groove 212, and the limiting plate 215 is fixedly connected to the inward end surface of the clamping rod 213. Through the setting of the limiting plate 215, the limiting effect of the clamping rod 213 can be effectively achieved, thereby avoiding the disconnection between the clamping rod 213 and the limiting member 211, and effectively ensuring the stability of the device.

[0033] Working principle: when in use, align the limiting piece 211 on the fan frame 22 with the fixing piece 29 and press it toward one side of the fixing ring 21. Under the action of the fixing piece 29, the clamping rod 213 will squeeze the clamping rod 213 toward the inside of the limiting piece 211, so that the clamping rod 213 can slide through the fixing piece 29, so that the clamping rod 213 is limited between the fixing piece 29 and the movable piece 28, thereby playing the role of limiting and fixing the fan frame 22 by the fixing ring 21. By analogy, the filter frame 24, the activated carbon frame 23, and the fan frame 22 can be effectively connected quickly. Then, the protective plate 33 fixedly connected inside the sliding block 34 is inserted into the inside of the guide groove 32, and the protective plate 33 is pushed along the filter frame 24 to one side of the fixing ring 21, so that the protective plate 33 is sleeved on the outer surfaces of the filter frame 24, the activated carbon frame 23, and the fan frame 22, thereby blocking the gap between the filter frame 24, the activated carbon frame 23, and the fan frame 22.

[0034] When the fixation needs to be released, the fan frame 22 is pressed toward one side of the fixing ring 21 again in the same pressing manner. At this time, the clamping rod 213 slides over the outer surface of the movable part 28 in the same manner again, so that the clamping rod 213 moves between the movable part 28 and the fixing seat 26, and then the activated carbon frame 23 is pulled outward. At this time, the clamping rod 213 will pull the movable part 28 closer to the fixing part 29. Since the movable part 28 and the fixing part 29 are both uppers, the clamping rod 213 will slide out along the inclined surface to the outside of the fixing part 29, thereby contacting the connection between the activated carbon frame 23 and the fan frame 22.
