Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Fig. 1～9, air-flow described in the utility model and laser combination detection device,
Including:
Shell 2, has an inner chamber 6,
The baffle plate 5 extended it is provided with in inner chamber in the middle part of the bottom surface of shell 2,
Inner chamber 6 is divided into left cavity and right cavity by baffle plate 5,
