[0030] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0031] like Figure 1 As shown, in one embodiment of this utility model, the laboratory environment monitoring device includes a container 1 and a gas extraction mechanism 2, a gas detection mechanism 3, a storage container 4, a separation mechanism 5, a direct emission mechanism 6, and a filtration emission mechanism 7 disposed inside the container 1. The input end of the gas extraction mechanism 2 is connected to the outside of the container 1; the output end of the gas extraction mechanism 2 is connected to the input end of the gas detection mechanism 3; the output end of the gas detection mechanism 3 is connected to the inside of the storage container 4; the input end of the separation mechanism 5 is connected to the inside of the storage container 4; the input ends of the direct emission mechanism 6 and the filtration emission mechanism 7 are respectively connected to the output end of the separation mechanism 5; and the output ends of the direct emission mechanism 6 and the filtration emission mechanism 7 are connected to the outside of the container 1.

[0032] This invention employs a separation mechanism to transport qualified gases detected by the gas detection device to the direct emission device and unqualified gases to the filtration emission device for filtration and emission. This reduces the number of filtration operations required by the filtration emission device, thereby improving the rationality of the filtration operation and ensuring its service life. Furthermore, it enables the separate emission of qualified and unqualified gases through different channels, increasing its functionality and effectively purifying unqualified gases, thus reducing the waste of air resources. In addition, the collection of detected gases in the storage container prevents gas leakage and loss, and also helps ensure the amount of subsequent direct and filtration emissions, ultimately providing more fresh air to the environment.

[0033] Specifically, in some implementations, such as Figure 1 As shown, the container 1 includes a box body 11 and a door 12 connected to the opening of the box body 11; a partition frame 103 is provided inside the box body 11; a detection chamber 101 and a processing chamber 102 are provided between the partition frame 103 and the box body 11; a gas extraction mechanism 2, a gas detection mechanism 3, and a storage container 4 are respectively arranged inside the detection chamber 101; a separation mechanism 5 is arranged on the partition frame 103; a direct discharge mechanism 6 and a filter discharge mechanism 7 are respectively arranged inside the processing chamber 102 to realize regional operation, thereby ensuring the orderly operation of each process.

[0034] Specifically, in some implementations, such as Figure 1 and 2 As shown, the gas extraction mechanism 2 includes a pump 21, a first input pipe 22, and a first output pipe 23. One end of the first input pipe 22 is connected to the inner wall of the housing 1 (middle box 11) and communicates with the outside of the housing 1 (middle box 11).

The output end of the pump 21 is connected to one end of the first output pipe 23. The other end of the first output pipe 23 is connected to the input end of the gas detection mechanism 3. This structure improves the gas extraction speed by accelerating the extraction action of the pump 21, thereby improving detection speed and efficiency. Specifically, the inner diameter of the end of the first input pipe 22 away from the pump 21 is larger than the inner diameter of the end of the first input pipe 22 closer to the pump 21; this increases the amount of gas extracted and further improves detection speed and efficiency.

[0035] Specifically, in some implementations, such as Figure 1 and 2As shown, the gas detection mechanism 3 includes a gas detector 31, a second input pipe 32, a second output pipe 33, and a mounting component 34.

The gas detector 31 mainly uses a gas sensor to detect the types of gases present in the environment. The gas sensor is a sensor used to detect the composition and content of gases. Furthermore, the gas detector 31 can be an RC-0910 VOC detector, a PCT-LB-00 VOC detector, or a PGM-7340 VOC detector.

The control valve 511 is a solenoid valve. This structure, through the accelerating delivery action of the discharge pump 52 and the controlling on / off action of the control valve 511, ensures the accuracy of gas discharge, thereby improving the accuracy and efficiency of discharge.

[0037] Specifically, in some implementations, such as Figure 1 and 3 As shown, the direct discharge mechanism 6 includes a direct discharge pipe 611; one end of the direct discharge pipe 611 is connected to the output end of the separation mechanism 5 (middle tee pipe 51); the other end of the direct discharge pipe 611 is connected to the outside of the container 1 (box 11).

[0038] Specifically, in some implementations, such as Figure 1 and 3 As shown, the filtration and discharge mechanism 7 includes a third input pipe 71, a third output pipe 72, and a filter cartridge 73; one end of the third input pipe 71 is connected to the output end of the separation mechanism 5 (the three-way pipe 51); the other end of the third input pipe 71 is connected to the input end of the filter cartridge 73; one end of the third output pipe 72 is connected to the output end of the filter cartridge 73; and the other end of the third output pipe 72 is connected to the outside of the housing 1 (box 11).
