[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a fixed toxic gas detector, comprising a detector body 11, which is responsible for detecting and analyzing the collected gas; a mounting base column 12 is arranged at the bottom of the detector body 11, which can be fixed in a workplace that needs to be monitored to achieve long-term stable operation; a first connecting pipe 13 is arranged on the air inlet of the detector body 11, which adopts a hollow structure and can introduce the gas from the external area that needs to be monitored into the detector body 11; a filter component is arranged on the side of the first connecting pipe 13 away from the detector body 11, and the filter component includes a ventilation pipe 21, one end of the first connecting pipe 13 is connected to the ventilation pipe 21, and an air suction component is also arranged on the end of the ventilation pipe 21 away from the detector body 11, and the air suction component can actively collect the gas in the external area, which is beneficial to improving the detection efficiency.

[0027] Please refer to Figure 2 , Figure 3 and Figure 4As shown, a through cavity is opened in the ventilation pipe 21, which can smoothly conduct gas; a slot 22 is opened on the top of the through cavity, and a removable filter plate 23 is penetrated on the top of the slot 22, and the filter assembly also includes a plurality of groups of filter holes 24, and a plurality of groups of filter holes 24 are evenly opened on the filter plate 23; through the combination of the filter plate 23 and the filter holes 24, the gas entering the ventilation pipe 21 can be effectively filtered, so that the clean gas can enter the through cavity through the filter holes 24, and continue to be conducted through the ventilation pipe 21 to the detector body 11 for detection, which can effectively remove the influence of dirt in the environment on the detection result, and avoid impurities such as dirt from entering the detector body 11, thereby affecting the detection performance.

[0028] After being used for a period of time, the filter plate 23 and the filter holes 24 will gradually accumulate various dirt and impurities. These dirt will accumulate on the surface of the filter plate 23 and may also be blocked in the filter holes 24. If too much dirt accumulates on the filter plate 23, it will prevent the gas from passing through the filter holes 24 smoothly into the ventilation pipe 21, and the gas sampling volume will gradually decrease. At the same time, if the filter holes 24 are blocked for a long time, it will also affect the gas conduction efficiency in the ventilation pipe 21. Through the detachable design of the filter plate 23, when a large amount of dirt accumulates on the filter plate 23 after long-term use, it can be directly removed from the ventilation pipe 21. Then, the operator only needs to simply clean the surface of the filter plate 23 and the residue in the filter holes 24 to remove the accumulated dirt.

[0029] Please refer to Figure 3 and Figure 4 As shown, in order to facilitate the positioning and removal of the filter plate 23, a limit clamp 25 is set on the top of the filter plate 23, and the limit clamp 25 contacts the outer surface of the ventilation pipe 21, which can ensure the position of the filter plate 23 in the slot 22; at the same time, a handle 26 is set on the top of the limit clamp 25, providing a good contact point; when the filter assembly needs to be cleaned or replaced, the operator only needs to use the handle 26 to easily remove the filter plate 23 from the slot 22, thereby improving the maintenance efficiency of the detector.

[0030] Please refer to Figure 3 and Figure 4 As shown, the air intake component includes an air intake fan 31, and the air intake fan 31 is firmly connected to the ventilation pipe 21 through multiple sets of screws arranged on its circumference to ensure that the air intake fan 31 will not fall off or vibrate during operation; by starting the air intake fan 31 to generate negative pressure, the air flow conduction in the ventilation pipe 21 is strengthened, so that the gas entering the ventilation pipe 21 from the monitoring area through the filter component can be sucked in at a higher flow rate, thereby increasing the sampling volume of the detector per unit time.

[0031] Please refer to Figure 4As shown, the air intake component also includes an air intake hood 32. In order to protect the air intake fan 31 from external impacts, a protective hood 33 is arranged on the outer surface of the air intake hood 32. The protective hood 33 has good impact resistance and can effectively protect the internal structure of the fan. At the same time, a through hole is provided on one side of the protective hood 33 corresponding to the position of the air intake fan 31, and the air intake hood 32 is installed on the through hole. The setting of the air intake hood 32 plays a role in guiding gas. The gas can enter the air intake fan 31 through the through hole from a wider area, thereby expanding the monitoring range of the detector.

[0032] Please refer to Figure 2 As shown, the detector body 11 is connected to the second connecting tube 14 through one side, and the other end of the second connecting tube 14 is provided with an audible and visual alarm 15. The first connecting tube 13 and the second connecting tube 14 are both hollow tube structures. At the same time, the audible and visual alarm 15 is also electrically connected to the detector body 11; when the detector body 11 detects that the concentration of toxic gas exceeds the standard through the gas sample collected by the suction component, it will send an alarm signal to the audible and visual alarm 15; once the alarm signal is received, the audible and visual alarm 15 will immediately send an audible and visual alarm to warn the staff to pay attention to safety, which provides important reminders for the staff to take risk avoidance measures in time, thereby improving the safety protection level in the workplace.
