the steel wire rope has the characteristics of high strength, difficulty in breaking and the like, so that the reliability of the moving plate 4 pulled by the connecting wire 9 can be improved.

Preferably, in order to prevent the moving plate 4 from blocking the ventilation tube 12, a limit block 22 is arranged in the main body 1, the limit block 22 is located between the ventilation tube 12 and the moving plate 4, the limit block 22 is fixed on the inner wall of the main body 1, and the distance between the limit block 22 and the moving plate 4 is greater than the length of the sealing rod 5.

the limiting block 22 is used for preventing the moving plate 4 from excessively moving towards the direction close to the ventilation pipe 12 to block the ventilation pipe 12, and a limiting effect is achieved.

During the use of the device, cold air is blown out by an air conditioner, the temperature of the air in the fixed pipe 6 is reduced, the air pressure between the movable disk 8 and the heat conducting disk 7 is reduced due to the far distance of expansion with heat and contraction with cold, so that the movable disk 8 is moved, the movable plate 4 is pulled by the connecting wire 9 to move, so that the sealing rod 5 is separated from the connecting hole, the cold air blown out by the air conditioner can enter the main body 1 from the connecting hole, the temperature in the main body 1 is reduced, heat dissipation is realized, the air in the main body 1 is conveyed to the nozzle 11 from the ventilating pipe 12 and is sprayed out towards the display screen 2 from the nozzle 11, so that dust on the display screen 2 is separated from the display screen 2 under the action of wind force, dust removal is realized, meanwhile, the magnet block 19 is opposite to the magnet plate 17 through the movement of the magnet block 19, and at the moment, mutually repulsive acting force is generated, therefore, the magnet plate 17 drives the extrusion plate 14 to move towards the direction away from the ventilation pipe 12 in the connecting box 13 through the push rod 16, cleaning liquid in the connecting box 13 is conveyed into the ventilation pipe 12 through the guide pipe 15, the cleaning liquid is sprayed on the display screen 2 under the action of wind power, and dust is driven through the flowing of the cleaning liquid on the display screen 2, so that the cleaning effect is improved.

Compared with the prior art, this a dust removal heat dissipation type navigation equipment for car has realized radiating function through heat dissipation mechanism, compare with current heat dissipation mechanism, this heat dissipation mechanism passes through the position of the sealed pole 5 of the temperature control of 1 outside air in main part, the effect of switch has been played, and belong to mechanical control, the interference killing feature is stronger, and current temperature control mostly realizes control through electronic equipment such as sensor, the interference killing feature is relatively weak, not only, the function of cleaing away the dust has still been realized through dust removal mechanism, compare with current dust removal mechanism, this dust removal mechanism adopts the wind-force that the air conditioner produced to remove dust, it is more energy-concerving and environment-protective, and being equipped with the washing liquid, dust removal effect is better.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
