[0031] See the accompanying drawings Figure 5 and Figure 6As shown, the outer side of the camera lens 4 is provided with a dry de-fogging structure 7 capable of de-fogging by absorbing water by the desiccant, and when the de-fogging head structure 5 moves to the position of the camera lens 4, the de-fogging head structure 5 can heat the moisture in the dry de-fogging structure 7 to dry. The dry de-fogging structure 7 comprises a dry ring 703 arranged on the outer side of the camera lens 4, the dry ring 703 is made of silica gel desiccant, the cross-sectional shape of the dry ring 703 is L-shaped, and a plurality of heat-conducting blocks 701 are connected to the dry ring 703 in the circumferential direction of the dry ring 703, and one end of the heat-conducting block 701 penetrates out of the camera main body 1. The heat-conducting block 701 and the dry ring 703 are provided with a conductive heating film 702 capable of converting electrical energy into heat energy to heat the camera lens 4. When the de-fogging head structure 5 moves to the position of the camera lens 4, the heat is quickly conducted to the dry ring 703 through the heat-conducting block 701, and the dehydration temperature of the dry ring 703 is controlled at 80-100 DEG C through the active heating of the conductive heating film 702, so that the dry ring 703 is recycled and utilized.

[0032] The working principle and technical effects of the present application are as follows: In use, the rotating column 11 in the camera main body 1 rotates under the drive of the second motor 10, drives the rotating rod 2 and the de-fogging head structure 5 at the end to rotate along the arc-shaped guide rail 3, and the blocking column 8 limits the rotating range thereof; when the de-fogging head structure 5 rotates to the position corresponding to the camera lens 4, the first motor 503 in the de-fogging shell 501 drives the rotating table 505 to rotate, so that the lens cloth 508 at the end can wipe the lens, at the same time, the heating body in the camera main body 1 transmits heat to the inner heat-conducting body 12 in the rotating rod 2 and the rotating column 11 through the heat-conducting silica gel pad 14 and the heat-conducting flexible belt 13, and then transmits the heat to the rotating table 505 made of phase change heat storage material through the heat-conducting sleeve 507, so as to realize heating and de-fogging; The camera main body 1 is a sports camera, which is usually used to shoot in a moving state, air is blown out from the air outlet hole 6 through the grating 502 of the de-fogging shell 501, the ventilation hole 506 of the rotating table 505, the ventilation groove of the arc-shaped guide rail 3 and the ventilation channel 301, which assists in blowing and de-fogging, and the blown air is hot air through the phase change heat storage material, so that better de-fogging effect is achieved; in addition, the dry ring 703 on the outer side of the camera lens 4 absorbs water to de-fog through the silica gel desiccant, when the de-fogging head structure 5 is close, the dry ring 703 can be heated to dry through the heat-conducting block 701, and the conductive heating film 702 between the heat-conducting block 701 and the dry ring 703 can also heat the camera lens 4 to de-fog, and when not in use, the de-fogging head structure 5 can be rotated to cover the lens to play a protective role; Therefore, the camera main body 1 de-fogging mode of the present application has the following modes: The first defogging mode is a direct contact defogging mode, that is, the first motor 503 drives the rotating table 505 to rotate, so that the lens cloth 508 at the end of the rotating table 505 rotates and wipes the lens. Before using this method, the outer surface of the arc-shaped guide rail 3 needs to be wiped first, so as to increase the service life of the lens cloth 508. One side of the blocking column 8 can be designed to be detachable, so as to increase the rotation angle range of the defogging head structure 5, and facilitate the disassembly, cleaning or replacement of the lens cloth 508 when rotating away from the camera main body 1. The second defogging mode is to store the heat generated when the camera main body 1 is running, and then when the camera lens 4 is foggy, the defogging head structure 5 is rotated to the position of the camera lens 4, and the phase change heat storage material is heated, so as to heat the camera lens 4 to a certain temperature. When moving away, the temperature of the camera lens 4 is higher than the ambient temperature, so as to prevent fogging. The third mode is a blowing defogging mode, which utilizes the characteristics of the sports camera that is often moved for shooting, collects and heats the wind, and accelerates, and blows the camera lens 4 from the side to defog. The fourth mode is a defogging mode through desiccant adsorption, and the dry defogging structure 7 can be dried by the heat of the defogging head structure 5, so as to achieve the purpose of recycling.
