[0042] During specific use, when demisting the windshield 1, the rotation of the first motor 401 drives the main bevel gear 402 to rotate. During the rotation of the main bevel gear 402, it is convenient to drive the driven bevel gear 403 to rotate. During the rotation of the driven bevel gear 403, it is convenient to drive the rotating shaft 404 to rotate. The rotation of the rotating shaft 404 drives the demisting disc at the bottom end to rotate to demist the windshield 1.

The air inlet of the air pump 506 is connected with a heating pipeline 507 through a pipeline.

[0044] During specific use, when demisting the windshield 1, the heating pipeline 507 heats the air. The heated air is conveyed to the conveying pipeline 504 by the air pump 506. Under the conveyance of the conveying pipeline 504, the air is conveyed to the exhaust shell 501. The hot air is dissipated through the air outlet grille 502 at the top of the exhaust shell 501 to demist and dry the windshield 1. The two exhaust channels 503 are provided to discharge the excess gas, facilitating the demisting of the glass.

[0045] The control mechanism 6 includes an installation and fixing shell 601 fixedly connected to the top of the exhaust air shell 501. A wireless signal receiver 602 is fixedly connected to the top of the installation and fixing shell 601. A signal transmitter 603 is arranged on one side of the signal receiver 602. A PLC controller 604 is arranged on one side of the signal transmitter 603. A data storage 605 is arranged on one side of the PLC controller 604. Humidity sensors 606 are fixedly connected to both sides of the windshield 1.

[0046] Through the mutual cooperation of the signal receiver 602 and the signal transmitter 603 on the control mechanism 6, it is convenient to remotely control the defogging of the vehicle. Through the transmission of information, it is convenient to control the defogging mechanism 4 and the hot air mechanism 5. The data storage 605 records the information during the defogging process for later inspection. When the water mist on the windshield 1 reaches a certain amount, the humidity sensor 606 senses the defogging of the windshield 1.

[0047] Working principle:

[0048] During the humidity detection of the windshield 1 for intelligent triggering of defogging, the device uses the humidity sensors 606 on both sides of the windshield 1 to continuously monitor the humidity on the glass surface. When the condensation amount of the water mist reaches the preset threshold, the signal receiver 602 transmits the data to the PLC controller 604, automatically starting the defogging program. Then, the water in the liquid storage tank 207 is preheated by the heater and transported to the nozzle 204 by the delivery pump 206 through the delivery pipe 205. The nozzle 204 is adjusted and unfolded through the linkage of the movable pin rod 2011 and the telescopic spring 202 to evenly spray warm water to dissolve the mist and ice. The first small motor 302 in the chute shell 301 drives the lead screw 3013 to drive the moving slide 303 to move up and down; the rack 305 meshes with the gear to achieve lateral sliding, and the lifting seat 309 is adjusted in height by combining the electric telescopic rod 3010 to ensure that the defogging seat 3014 closely fits the surface of the windshield 1. The first motor 401 drives the defogging disc to rotate through the main bevel gear 402 and the driven bevel gear 403 and the driving rotating shaft 404 to scrape the water mist on the surface. At the same time, the second motor 405 drives the defogging drum 4010 to roll through the first belt drive 407 and the second belt 409 to further remove the remaining water stains. The drying of the hot air mechanism 5 is strengthened. After heating the air through the heating pipe 507, the air pump 506 evenly blows the hot air towards the glass surface through the air outlet grille 502 of the exhaust air shell 501 to accelerate the evaporation of water. The excess gas is discharged through the exhaust passage 503. The PLC controller 604 dynamically adjusts the water spraying frequency, defogging stroke and hot air temperature according to the humidity data; the data storage 605 records the operation parameters to support the remote signal receiver 602 and the signal transmitter 603 to achieve remote control and maintenance optimization.
