anti-fog camera

Abstract

The invention discloses an anti-fog camera, which comprises a lens barrel, the lens barrel is embedded with a lens, and the side wall of the lens barrel is provided with a plurality of bar-shaped grooves at equal intervals along its circumference. The side wall is provided with a plurality of wedge-shaped air outlets communicating with the bar-shaped grooves. The lens barrel is embedded with a power generation assembly composed of a plurality of thermoelectric power generation sheets connected in series. Each of the wedge-shaped air outlets is embedded with a power generation assembly. The components are electrically connected to the heating wire, and the inner wall of the strip-shaped groove is fixedly connected with a telescopic airbag, and a driving device for driving the telescopic airbag to expand and contract is installed in the strip-shaped groove. The invention drives the telescopic air bag back and forth through the electromagnet, blows high-speed air to the lens, and the blown air can quickly evaporate the water mist on the lens after being heated by the electric heating wire, so as to avoid the long-term condensation of water mist on the camera lens and affect the monitoring clarity.

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
