[0019] See also Figure 1-4 The utility model provides a technical solution: a camera capable of preventing the lens from fogging, comprising a camera body 1, a mirror 2 is arranged on the front of the camera body 1, an arc-shaped convex plate is arranged on the top of the camera body 1 for shielding sunlight, a heating shell 3 is fixedly installed on the upper surface of the arc-shaped convex plate of the camera body 1, a heating cavity 4 is opened in the heating shell 3, a plurality of heating copper tubes 5 are arranged in the heating cavity 4 in a circular array, the heating copper tubes 5 are wavy, and one end of the heating copper tube 5 passes through the rear side of the heating shell 3. The surface of the heating shell 3 is fixedly installed with an air pump 7 on the back side, and the output port of the air pump 7 is fixedly connected to one end of the heating copper tube 5 located outside the heating shell 3. A number of heating rods 6 are fixedly installed in the heating chamber 4. A temperature and humidity sensor is provided on the camera body 1 for detecting the temperature and humidity outside the camera body 1. Therefore, the air pump 7 and the heating rod 6 can be turned on according to the data detected by the temperature and humidity sensor. An air outlet slot 8 extending from the lower surface of the arc-shaped convex plate is provided in the heating shell 3. The other end of the heating copper tube 5 passes through the top wall of the air outlet slot 8 and faces the mirror surface 2;
[0020] When the temperature and humidity sensor detects that the humidity of the external environment of the camera body 1 is high and the external environment temperature is lower than the temperature of the camera body 1, the heating rod 6 starts to preheat the internal environment temperature of the heating chamber 4. After heating for a period of time, the air pump 7 starts and draws external air to the heating copper tube 5. After the gas entering the heating copper tube 5 is heated by the heating rod 6, the temperature rises. The heated gas is finally blown from the air outlet slot 8 to the outer surface of the mirror 2, thereby achieving the purpose of drying the mirror 2. When the external environment of the camera body 1 is relatively humid, the problem of water vapor generated on the surface of the mirror 2 is avoided as much as possible, and the shooting effect of the camera is further improved.
[0021] In this solution, since the heating copper tube 5 is wavy, the transportation time and heating time of the gas in the heating copper tube 5 are increased, and the heating effect of the gas is further improved.
[0022] In this solution, an activated carbon filling layer is provided in the outlet of the air pump 7 to absorb water vapor in the air, thereby preventing excessive water vapor from entering the heating copper tube 5 as much as possible, thereby ensuring the dryness of the gas blown to the mirror surface 2.
[0023] The front face of the camera body 1 is rotatably connected to a gear 17, and a cleaning scraper 18 is fixedly connected to the lower surface of the gear 17. A rubber scraper is installed on the side of the cleaning scraper 18 close to the camera body 1, and the rubber scraper is in contact with the outer surface of the mirror 2. When the gear 17 rotates back and forth, it can drive the cleaning scraper 18 to swing back and forth, so that the rubber scraper can scrape off the fog that has formed on the mirror 2, further improving the cleaning effect and speed of the fog on the surface of the mirror 2, and reducing the influence of the fog on the shooting of the camera.
[0024] The front of the camera body 1 is fixedly connected to two horizontally arranged mounting seats 14, a connecting slide bar 15 is fixedly connected between the two mounting seats 14, a rack 16 is fixedly sleeved on the outer surface of the connecting slide bar 15, and the lower side of the rack 16 is meshed with a gear 17, so when the rack 16 slides on the connecting slide bar 15, the rack 16 can synchronously drive the gear 17 to rotate back and forth.
[0025] A rotating shaft 9 is rotatably connected between the inner walls on both sides of the air outlet slot 8. A fan blade 10 is fixedly sleeved on the outer surface of the rotating shaft 9. The blades on one side of the fan blade 10 are located directly below the air outlet of the heating copper tube 5. A first pulley 11 is fixedly sleeved on the outer surface of the rotating shaft 9. A second pulley 12 is rotatably connected to the front of the camera body 1. A transmission belt 13 is transmission-connected between the first pulley 11 and the second pulley 12. A driving disc 20 is fixedly connected to the front of the second pulley 12. A T-shaped shaft 21 is fixedly connected to the front of the driving disc 20. The T-shaped shaft 21 is arranged on a side away from the center of the driving disc 20. A rotating push plate 22 is rotatably sleeved on the transverse axis of the T-shaped shaft 21. The other side of the rotating push plate 22 is hinged to the rack 16.
[0026] When the dried gas is blown out through the air outlet of the heated copper tube 5, the gas will form a thrust on the blades of the fan blades 10, thereby driving the fan blades 10 to rotate, and the rotating shaft 9 rotates synchronously with the fan blades 10, so that the first pulley 11 rotates, and the second pulley 12 rotates synchronously under the drive of the transmission belt 13, the driving disc 20 rotates with the second pulley 12, and drives the T-shaped shaft 21 to move in a circular direction, so that the T-shaped shaft 21 can form a thrust or a pulling force on the rotating push plate 22, so that the rack 16 slides back and forth on the connecting slide rod 15.
[0027] In this solution, the diameter of the first pulley 11 is one third of the diameter of the second pulley 12, which reduces the force required for the first pulley 11 to drive the second pulley 12 and avoids the problem that the first pulley 11 has difficulty driving the second pulley 12 to rotate.
[0028] A return spring 19 is fixedly connected between the side surface of the rack 16 facing the driving disc 20 and the mounting seat 14. The return spring 19 is movably sleeved on the outer surface of the connecting slide rod 15. When the second pulley 20 stops running, the return spring 19 will exert a thrust on the rack 16, causing the rack 16 to move to the initial position, thereby allowing the cleaning scraper 18 to swing out of the mirror surface 2 without blocking the mirror surface 2.
[0029] Working principle: When the temperature and humidity sensor detects that the humidity outside the camera body 1 is high and the external environment temperature is lower than the temperature of the camera body 1, the heating rod 6 starts to preheat the internal environment temperature of the heating chamber 4. After heating for a period of time, the air pump 7 starts to draw external air to the heating copper tube 5. After the gas entering the heating copper tube 5 is heated by the heating rod 6, the temperature rises. The heated gas is finally blown from the air outlet slot 8 to the outer surface of the mirror 2, thereby achieving the purpose of drying the mirror 2.
[0030] When the dried gas is blown out through the air outlet of the heated copper tube 5, the gas will form a thrust on the blades of the fan blade 10, thereby driving the fan blade 10 to rotate, and the rotating shaft 9 rotates synchronously with the fan blade 10, so that the first pulley 11 rotates, and the second pulley 12 rotates synchronously under the drive of the transmission belt 13, the driving disc 20 rotates with the second pulley 12, and drives the T-shaped shaft 21 to move in the circumferential direction, so that the T-shaped shaft 21 can form a thrust or a pulling force on the rotating push plate 22, so that the rack 16 slides back and forth on the connecting slide rod 15, and the rack 16 can synchronously drive the gear 17 to rotate back and forth, driving the cleaning scraper 18 to swing back and forth, so that the rubber scraper can scrape off the fog that has formed on the mirror surface 2.
