Anti-fog camera

Abstract

The invention discloses an anti-fog camera which comprises a lens barrel, a lens is embedded in the lens barrel; a plurality of strip-shaped grooves are formed in the side wall of the lens barrel at equal intervals in the circumferential direction of the lens barrel; a plurality of wedge-shaped air outlets communicated with the strip-shaped groove are formed in the side wall of the lens barrel; apower generation assembly formed by connecting a plurality of thermoelectric power generation pieces in series is embedded in the lens barrel, an electric heating wire electrically connected with thepower generation assembly is embedded in each wedge-shaped air outlet, a telescopic air bag is fixedly connected to the inner wall of the strip-shaped groove, and a driving device for driving the telescopic air bag to stretch out and draw back is installed in the strip-shaped groove. The electromagnet drives the telescopic air bag to stretch back and forth to blow out high-speed air to the lens, the blown-out air can rapidly evaporate water mist on the lens after being heated by the electric heating wire, and the situation that monitoring definition is affected due to the fact that water mistis condensed on the lens of the camera for a long time is avoided.

Description

technical field [0001] The invention relates to the technical field of placing monitoring equipment, in particular to an anti-fog camera. Background technique [0002] Surveillance camera is a semiconductor imaging device, which has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, and anti-vibration. Surveillance camera security system. [0003] When the outside air temperature is low and the humidity is high (for example, in the early morning or evening in autumn and winter), the high-concentration and low-temperature water vapor in the air contacts the outer surface of the lens of the camera, and the internal electronic components of the camera heat up when the camera is working. Therefore, the temperature is high, and the low-temperature water vapor will liquefy on the outer surface of the high-temperature lens and form a layer of water mist, which greatly reduces the clarity of camera monitoring. Since the cameras used for monitor...

[0003] When the outside air temperature is low and the humidity is high (for example, in the early morning or evening in autumn and winter), the high-concentration and low-temperature water vapor in the air contacts the outer surface of the lens of the camera, and the internal electronic components of the camera heat up when the camera is working. Therefore, the temperature is high, and the low-temperature water vapor will liquefy on the outer surface of the high-temperature lens and form a layer of water mist, which greatly reduces the clarity of camera monitoring. Since the cameras used for monitoring are generally installed at high places, this makes It is very inconvenient to clean up the water mist, and in some key monitoring places (such as banks), a large number of cameras will be installed, and it will take a long time to clean up the water mist
