Technical Field

[0001] The invention relates to the technical field of automobile equipment, and in particular to a vehicle window defogger based on the water vapor liquefaction principle. Background Art

[0002] The biggest role of cars is to expand the radius of people's daily lives and speed up the transportation of goods. Cars can improve the quality of life, make holiday travel more convenient, and provide the possibility when unexpected fast transportation is needed.

[0003] During the cold season, drivers will turn on the air conditioner in their cars to raise the temperature inside the car. However, the rising temperature inside the car causes a temperature difference between the inside and outside of the windows. A layer of mist forms on the inner surface of the windows. This is caused by the liquefaction of water vapor. Liquefaction refers to the transformation of a substance from a gas to a liquid. The process is called liquefaction. Liquefaction is an exothermic process, which makes it difficult for the driver to see the rearview mirror and the situation around the car, increases the driver's blind spot, and increases the possibility of accidents while the car is driving.

[0004] To this end, we propose a car window defogger device based on the principle of water vapor liquefaction to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of fogging of automobile windows in cold seasons, and to propose a window defogger device based on the principle of water vapor liquefaction.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A vehicle window defogger device based on the principle of water vapor liquefaction comprises a vehicle door, a side wall of the vehicle door is provided with a vehicle window body, a permanent magnet is embedded in the side wall of the vehicle door, two symmetrically distributed slide grooves are provided on the side wall of the vehicle door, a slide plate is slidably connected to the side wall of the slide groove, an electromagnet is embedded in the side wall of the slide plate, the S pole of the electromagnet is opposite to the S pole of the permanent magnet, a first electric contact is provided on the side wall of the vehicle door, a second electric contact is provided on the side wall of the vehicle door, a placement groove is opened on the side wall of the vehicle door, a sponge is placed on the bottom side wall of the placement groove, and the placement groove is located at the lower end of the vehicle window body.

[0008] Preferably, the shortest distance between the bottom side wall of the first electrical contact and the top side wall of the placement groove is 1.5 cm, and the shortest distance between the bottom side wall of the second electrical contact and the top side wall of the placement groove is 3 cm.

[0009] Preferably, a spring is fixedly connected to the side wall of the vehicle door, an end of the spring away from the vehicle door is fixedly connected to a stopper, a limiting tube is sleeved on the side wall of the spring, and one end of the limiting tube is fixedly connected to the side wall of the vehicle door.

[0010] Preferably, the side wall of the placement groove is covered with a smooth film, and the side wall of the placement groove is provided with rounded corners.

[0011] Preferably, the side wall of the vehicle door is fixedly connected to a support block, the side wall of the support block is inserted with an air duct, one end of the air duct is fixedly connected to an air outlet duct, the shape of the air outlet duct is a prism, the opening of the air outlet duct faces upward, and the distance between the side wall of the air outlet duct and the vehicle window body is 7 cm.

[0012] Preferably, the side walls of the air outlet duct and the side walls of the support block are both provided with rounded corners.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when the temperature difference between the inside and outside of the car is large, water mist forms on the surface of the car window, and the water mist forms a closed circuit between the first electric contact and the second electric contact through the water mist. The first electric contact and the second electric contact introduce the current of the car battery to the electromagnet, so that the electromagnet is energized to generate magnetic force. The S pole of the electromagnet is opposite to the S pole of the permanent magnet, and the permanent magnet forms a repulsive force on the energized electromagnet, so that the electromagnet drives the slide plate to move downward, and pushes the water mist of the car window body into the sponge. The first electric contact and the second electric contact are disconnected due to the removal of the water mist, resulting in the electromagnet being powered off, and the non-conductive electromagnet is attracted upward by the permanent magnet, so that the electromagnet drives the slide plate to move upward, and the slide plate returns to its original position. When the water mist appears again, the water mist can be removed again;

[0015] 2. The present invention utilizes an air duct, and the hot air from the air conditioner passes through the air duct, then passes through the air outlet duct, and is blown toward the surface of the vehicle window body by the air outlet duct again, thereby achieving the effect of blowing the hot air to the vehicle window body. The prism shape of the air outlet duct is utilized to expand the hot air in the air duct, ensuring that every part of the vehicle window body can receive the hot air, thereby reducing the temperature difference between the inside and outside of the vehicle window body. The hot air discharged from the air outlet duct can also be used to blow away the water vapor around the vehicle window body, thereby reducing the water mist attached to the surface of the vehicle window body.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Embodiment 1:

[0024] Reference Figure 2-4 A vehicle window defogger device based on the principle of water vapor liquefaction comprises a vehicle door 1, a vehicle window body 2 is arranged on the side wall of the vehicle door 1, and is characterized in that a permanent magnet 15 is embedded in the side wall of the vehicle door 1, and two symmetrically distributed slide grooves 6 are arranged on the side wall of the vehicle door 1, and a slide plate 7 is slidably connected to the side wall of the slide groove 6, and an electromagnet is embedded in the side wall of the slide plate 7, and the S pole of the electromagnet is opposite to the S pole of the permanent magnet 15, a first electric contact 8 is arranged on the side wall of the vehicle door 1, and a second electric contact 9 is arranged on the side wall of the vehicle door 1, and a placement groove 10 is opened on the side wall of the vehicle door 1, and a sponge 11 is placed on the bottom side wall of the placement groove 10, and the placement groove 10 is located at the lower end of the vehicle window body 2, and the electromagnet, the first electric contact 8 and the second electric contact 9 are electrically connected, and the connection method and working principle between the electrical components belong to the well-known technology in the field, and no more details are given here.

[0025] The shortest distance between the bottom side wall of the first electrical contact 8 and the top side wall of the placement groove 10 is 1.5 cm, and the shortest distance between the bottom side wall of the second electrical contact 9 and the top side wall of the placement groove 10 is 3 cm.

[0026] By taking advantage of the fact that the shortest distance between the bottom side wall of the first electrical contact 8 and the top side wall of the placement groove 10 is 1.5 cm and the shortest distance between the bottom side wall of the second electrical contact 9 and the top side wall of the placement groove 10 is 3 cm, it can be ensured that the circuit of the electromagnet will be disconnected only when the slide plate 7 slides to the bottom of the window body 2, ensuring that the slide plate 7 can push all the rainwater on the window body 2 into the sponge 11, avoiding the electromagnet from being powered off too early, thereby being sucked up by the suction force of the permanent magnet 15, resulting in the water mist on the window body 2 not being removed.

[0027] A spring 13 is fixedly connected to the side wall of the vehicle door 1 , and a stopper 14 is fixedly connected to one end of the spring 13 away from the vehicle door 1 . A limiting tube 12 is sleeved on the side wall of the spring 13 , and one end of the limiting tube 12 is fixedly connected to the side wall of the vehicle door 1 .

[0028] A spring 13 is fixedly connected to the side wall of the vehicle door 1, and a stopper 14 is fixedly connected to the end of the spring 13 away from the vehicle door 1. When the permanent magnet 15 forms a repulsive force with the electromagnet, the slide plate 7 moves downward to push the water mist of the vehicle window body 2 into the sponge 11. At the same time, the slide plate 7 presses the stopper 14 downward, and the stopper 14 presses the spring 13. Then the electromagnet is powered off, and the spring 13 is reset. The spring 13 pushes the stopper 14 upward, and the stopper 14 pushes the slide plate 7 upward, so that the distance between the permanent magnet 15 and the powered-off electromagnet becomes shorter, ensuring that the electromagnet can be attracted by the permanent magnet 15, thereby resetting the slide plate 7.

[0029] The side wall of the placement groove 10 is covered with a smooth film, and the side wall of the placement groove 10 is provided with rounded corners.

[0030] The side wall of the placement groove 10 is covered with a smooth film to reduce dust adhesion in the placement groove 10. The side wall of the placement groove 10 is provided with a rounded corner to prevent the side wall of the placement groove 10 from scratching the people in the car and causing discomfort to the people in the car, especially when there are children in the car, to avoid irreversible damage to the children.

[0031] In the present invention, when the temperature difference between the inside and outside of the car is large, water mist forms on the surface of the car window, and the water mist forms a closed circuit with the first electric contact 8 and the second electric contact 9 through the water mist. The first electric contact 8 and the second electric contact 9 introduce the current of the car battery to the electromagnet, so that the electromagnet is energized to generate magnetic force. The S pole of the electromagnet is opposite to the S pole of the permanent magnet 15, and the permanent magnet 15 forms a repulsive force on the energized electromagnet, so that the electromagnet drives the slide plate 7 to move downward, and pushes the water mist of the car window body 2 into the sponge 11. The first electric contact 8 and the second electric contact 9 are disconnected due to the removal of water mist, resulting in the electromagnet being powered off. The non-conductive electromagnet is attracted upward by the permanent magnet 15, so that the electromagnet drives the slide plate 7 to move upward, and the slide plate 7 returns to its original position. When water mist appears again, the water mist can continue to be removed.

[0032] Embodiment 2:

[0033] Reference Figure 1 The difference from the first embodiment is that: a support block 3 is fixedly connected to the side wall of the door 1, an air guide duct 4 is inserted into the side wall of the support block 3, an air outlet duct 5 is fixedly connected to one end of the air guide duct 4, the shape of the air outlet duct 5 is a prism, the opening of the air outlet duct 5 faces upward, and the distance between the side wall of the air outlet duct 5 and the window body 2 is 7 cm.

[0034] The side walls of the air outlet pipe 5 and the side walls of the support block 3 are both provided with rounded corners.

[0035] The side walls of the air outlet duct 5 and the side walls of the support block 3 are both provided with rounded corners to avoid scratching passengers.

[0036] Liquefaction refers to the transformation of a substance from a gaseous state to a liquid state, and the process is called liquefaction. Liquefaction is an exothermic process. There are two ways to achieve liquefaction: one is to lower the temperature, and the other is to compress the volume. Usually, the volume of a gas will become a few thousandths of its original size after liquefaction, and a large amount of heat will be released at the same time. Different gases have different liquefaction critical points at different temperatures and pressures. Therefore, it must be cooled to absorb heat while pressurizing. The air duct 4 is used, and the hot air from the air conditioner passes through the air duct 4, and then passes through the air outlet 5 from the air duct 4, and then blows to the surface of the window body 2 through the air outlet 5 again, so as to achieve the effect of blowing the hot air to the window body 2. The prism shape of the air outlet duct 5 is used to expand the hot air of the air duct 4, ensure that the window body 2 can receive the hot air at every place, and reduce the temperature difference between the inside and outside of the window body 2. The hot air discharged from the air outlet duct 5 can also be used to blow away the water vapor around the window body 2 and reduce the water mist attached to the surface of the window body 2.
