Description
Technical Field
The utility model relates to a sensor technical field, concretely relates to sleet detects sensor based on vortex heat energy.
Background
When the traditional rain and snow sensor works in an environment of-20 ℃, due to low heating efficiency and slow temperature rise, ice and snow blocks cannot be timely dissolved after snow flows down, false detection is caused, and the traditional rain and snow sensor is mistakenly regarded as always in a snowing state; resistance wires or ceramic heating sheets are generally adopted in the prior art to heat rain and snow, the speed is low, the power consumption is high, snow blocks cannot be completely dissolved at minus 20 ℃, a large amount of residual water is easy to freeze again after being dissolved, and sensor detection failure can be caused due to untimely treatment.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is, overcome the above-mentioned defect that prior art exists, provide energy-conserving and can in time ensure a rain and snow detection sensor based on vortex heat energy that normally detects.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a sleet detects sensor based on vortex heat energy, includes mount pad, PCB board, eddy current coil, conducting strip and temperature sensor, the PCB board is located in the mount pad, eddy current coil locates in the PCB board, the conducting strip subsides are adorned on the PCB board, one side of mount pad is equipped with temperature sensor, temperature sensor all is equipped with the wire with eddy current coil.
Furthermore, an anti-interference coil is arranged on the PCB and is arranged on the periphery of the eddy current coil.
Further, the heat conducting sheet is a metal heat conducting sheet.
Furthermore, the heat conducting sheet is attached to the back surface of the PCB.
Furthermore, the PCB is provided with a connecting hole, a bolt connected with the mounting seat is arranged in the connecting hole, and the outer side of the mounting seat is connected with a mounting block provided with a mounting hole.
Further, the mounting seat is frame-shaped.
