The air path connector 41 can be one, which is connected and communicated with the electromagnetic valve 32, and in other examples, a plurality of air paths can be arranged, for example, to input other air paths to clean the light-transmitting window 121 of the front cover assembly 12, etc. In order to improve the protection, the plug interface of the shell of the connector 40 is directed obliquely downward, that is, away from the top of the shroud 10, so as to prevent the entry of dust and water vapor and rainwater.

[0082] On the basis of the partition plate 14, the line interface 142 is arranged on the partition plate 14, so as to facilitate the connection of the core 50 with the external circuit, and ensure the regularity and compactness of the line. The line interface 142 is used for sealingly penetrating the connecting cable, so as to ensure the sealing of the front cavity 10a1.

[0083] Please refer to Figure 1 and Figure 2 The utility model also proposes a camera 100, including core 50 and protection structure, protection structure is any protection structure above, core 50 is installed in installation cavity 10a. Since the protection structure in the camera 100 refers to the protection structure of any of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0084] Optionally, a support 60 is arranged at the bottom of the shroud 10, and the support 60 is movably connected with the shroud 10, so as to adjust the pitch angle of the core 50 to adapt to different detection environments and requirements. Specifically, the support 60 comprises a horizontal plate and vertical plates connected to both ends of the horizontal plate, and the vertical plates are rotatably connected with the opposite sides of the shroud 10, so as to improve the structural stability and the convenience of adjustment.

[0085] The above description is only the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the contents of the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
