DETAILED DESCRIPTION

[0021] See also Figure 1-4The utility model relates to a dustproof camera, comprising a dust cover cavity 1, a camera housing 2, a camera back cover 3, a baffle 4, a baffle groove 5, a baffle sheet 6 and a dust cover back cover 7. The camera head and the circuit board are built in the camera housing 2. The dust cover cavity 1 is provided with a baffle sheet 6, a baffle groove 5, a baffle plate 4, a camera housing 2 and a camera back cover 3 from front to back. The head of the camera housing 2 is in a hemispherical shell shape, and the head of the camera housing 2 extends into the baffle groove 5 through the baffle plate 4. A certain distance is maintained between the mirror surface of the camera and the baffle 6, and an air outlet 6.1 is provided on the baffle 6 corresponding to the camera. The aperture of the air outlet 6.1 is larger than the outer diameter of the mirror surface of the camera. The baffle 6 is limited by the baffle groove 5, and the baffle groove 5 is provided with a limiting groove corresponding to the baffle 6. The tail of the camera housing 2 is blocked by the camera back cover 3, and the camera housing flange 2.1 at the tail of the camera housing 2 is connected to the camera back cover 3 by bolts, and a cable stuffing box 8 is provided on the camera back cover 3.

[0022] The camera back cover 3 is limited by a retaining spring 9 to prevent the camera back cover 3 and the camera housing 2 from axial movement. A retaining groove is provided on the inner wall of the dust cover cavity 1 corresponding to the retaining spring 9 .

[0023] The tail of the dust cover cavity 1 is sealed by a dust cover back cover 7, and the dust cover flange 1.1 at the tail of the dust cover cavity 1 is connected to the dust cover back cover 7 by bolts. The dust cover back cover 7 is provided with a cable stuffing box 8 and an air nozzle 10.

[0024] An air duct 11 is provided between the camera housing 2 and the dust cover cavity 1, the camera back cover 3 is evenly distributed with primary air holes 3.1, the camera housing flange 2.1 is provided with secondary air holes 2.1.1, the primary air holes 3.1 and the secondary air holes 2.1.1 correspond one to one, and the baffle 4 is provided with tertiary air holes 4.1.
