AI Technical Summary
During the car driving, especially in autumn and winter, due to the large temperature difference inside and outside the car and the high humidity, the water vapor in the car condenses onto the inner windshield of the car, affecting the driver's vision. The existing defogging methods are inconvenient during driving, which may distract the driver's attention and increase the risk of traffic accidents.
A window defog removal device is designed, including a car window and a wiper. A scraper is installed on the inside of the window. The scraper is coated with water-absorbing substances, such as felt. The scraper moves synchronously with the wiper through a permanent magnet, and is fixed in the window by a suction cup device, and defog removal is achieved through pulling ring operation.
This device does not increase energy consumption and is easy to use. It can quickly and effectively remove fog in the car windows, avoid distracting the driver's attention and improve driving safety.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile equipment, and in particular to a vehicle interior window defogger. Background Art
[0002] With the continuous improvement of people's living standards, the number of cars is increasing. Cars have expanded the radius of people's daily lives, accelerated the transportation speed of goods, improved the quality of life, made holiday travel more convenient, and provided the possibility of rapid transportation when unexpected accidents are needed. Therefore, it is particularly important to improve the driving safety of drivers. During the driving process, especially in autumn and winter, due to the large temperature difference between the inside and outside of the car and high humidity, when the temperature inside the car is high and the temperature outside is low, the water vapor inside the car will condense on the inner glass of the front windshield of the car, affecting the driver's vision. In serious cases, the driver will not be able to see the situation around the car at all. Therefore, the fog on the upper surface of the front windshield must be cleared in time to ensure driving safety.
[0003] At present, there are many methods for defogger, such as opening the car windows appropriately to allow air to circulate inside and outside the car and reduce the temperature difference between inside and outside the car to eliminate the fog condensed on the inner surface of the windshield; or turning on the air conditioner to adjust the temperature in the car to eliminate the fog on the windshield; or wiping with a towel or paper towel to achieve the purpose of defogger. Although these methods can effectively defog, they bring inconvenience to the driver when the car is driving. When it is very cold or hot, rainy or snowy, or driving at high speed, it is not advisable to open the car windows to defog. The driver wipes the defogger with a towel or paper towel while driving, which will distract the driver's attention, easily cause traffic accidents, and affect driving safety. Turning on the air conditioner not only requires increased energy consumption but also takes a certain amount of time to produce an effect. Therefore, there is an urgent need for a timely and effective method to remove fog. Summary of the invention
[0004] The present invention solves the above-mentioned deficiencies in the prior art and provides a demisting device which is not only effective but also does not require additional energy consumption and is convenient to use.
[0005] In order to achieve the above functions, the present invention adopts a vehicle window defogger, including a vehicle window and a windshield wiper, a scraper is arranged at a position on the inner side of the vehicle window corresponding to the windshield wiper, a water-absorbing material that can scrape off water mist is arranged on the scraper, and a permanent magnet that attracts each other is arranged on the wiper and the scraper respectively, the scraper is connected to a suction cup device fixed on the inner side of the vehicle window through a connecting rod, and the scraper rotates in an arc with the suction cup device as the center. Since the scraper for scraping off water mist does not need to scrape off continuous raindrops like the wiper outside the window and the total amount of water mist scraped off is not large, and since there are also precision electronic components in the instrument panel inside the vehicle window, direct scraping and letting it drip freely cannot be adopted, for this reason, a water-absorbing material is used on the scraper to scrape off the water mist, and the water-absorbing material can be a water-absorbing sponge, preferably felt, especially It is wool felt. In order to make the scraper and the wiper run synchronously, permanent magnets with opposite poles attracting each other are arranged on the wiper and the scraper. The permanent magnet can be a whole piece, or it can be made of small pieces connected end to end or evenly distributed. The scraper is fixed to the inside of the window by a suction cup device in the window. The suction cup device is placed near the center of the circle of the external wiper movement trajectory to ensure that the scraper can be driven to move synchronously when the wiper moves. At the same time, a lock with a self-locking function is arranged on the suction cup base. When the lock tongue is released, the scraper and the wiper can move synchronously. When the lock tongue is locked, the scraper cannot move. This ensures that the wiper moves alone when there is no fog on the window. In order to ensure the operation of the lock, a pull rope is connected to the lock rope, and a pull ring is connected to the other end of the pull rope. The pull ring is placed in a convenient place on the dashboard.
[0006] The defogger device designed in the above manner not only does not increase energy consumption but is also very convenient to use. The mist in the car window can be eliminated by simply pulling the pull ring without affecting the function of the original wiper. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 A schematic diagram of a vehicle window defogger device according to the present invention; Figure 2 for Figure 1 AA section view. DETAILED DESCRIPTION
[0008] Now combined with the attached Figure 1 , Attachment Figure 2To further illustrate the embodiments of the invention, a vehicle window defogger comprises a vehicle window 11 and a wiper 1, a scraper 2 is arranged on the inner side of the vehicle window 11 at a position corresponding to the wiper 1, a water-absorbing material 6 for scraping off water mist is arranged on the scraper 2, and a permanent magnet 4 and 5 that attract each other are arranged on the wiper 1 and the scraper 2, respectively, the scraper 2 is connected to a suction cup device 13 fixed on the inner side of the vehicle window through a connecting rod 3, because the scraper 2 for scraping off water mist does not need to scrape off continuous raindrops like the wiper 1 outside the window and the total amount of water mist scraped off is not large, and because the vehicle window 11 also has precision electronic components in the inner instrument panel, it cannot be scraped directly and allowed to drip freely, for this reason, a water-absorbing material 6 is used on the scraper 2 to scrape off water mist, and the water-absorbing material can be a water-absorbing sponge, preferably felt, especially wool felt, in order to make the scraper 2 and the wiper 1 can Synchronous operation, permanent magnets 4 and 5 with opposite poles attracting each other are arranged on the wiper 1 and the scraper 2. The permanent magnets 4 and 5 can be a whole piece, or they can be connected end to end or evenly distributed in small pieces. The scraper 2 is fixed to the inside of the vehicle window 11 by the suction cup 9 of the suction cup device 13 in the vehicle window 11. The suction cup device 13 is placed near the center of the movement trajectory of the external wiper 1 to ensure that the scraper can be driven to move synchronously when the wiper moves. At the same time, a lock buckle 7 with a self-locking function is arranged on the base of the suction cup device 13. When the lock tongue is released, the scraper 2 and the wiper 1 can move synchronously. When the lock tongue is locked, the scraper 2 cannot move. This ensures that the wiper moves alone when there is no fog on the vehicle window. In order to ensure the operation of the lock buckle 7, a pull rope 21 is connected to the lock buckle 7, and the other end of the pull rope 21 is connected to a pull ring 7. The pull ring 8 is placed at a convenient place on the dashboard.
