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,
At the upper surface of shell 2 corresponding to left cavity, being provided with air inlet 7, air inlet 7 is with interior Chamber 6 connects,
At the lower surface of shell 2 corresponding to right cavity, being provided with taper bucket 3, taper bucket 3 is with interior Chamber 6 connects,
