Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

The utility model provides a glass defogging system, includes air supply subassembly 1, main shaft 2 and cam 3, air supply subassembly 1 includes inner bag 11, piston 12, spring 13 and

shell

14, 11 fixed connection of inner bag are in shell 14, be equipped with a plurality of blow vents 11a on the inner bag 11, the top and the lower part of shell 14 are equipped with air inlet 14a and gas outlet 14b respectively, 12 sliding connection of piston is in inner bag 11, be equipped with spring 13 between the top of piston 12 and the inner bag 11, the bottom of piston 12 is equipped with

universal ball

15, 3 sliding connection of cam is on main shaft 2 and through the drive of hydraulic system 4. The ball 15 reduces friction and thereby facilitates the sliding of the cam under the piston 12.

In this embodiment, the air inlet 14a is provided with a one-way valve 5, and the one-way valve 5 is connected with the air inlet duct 6. The air inlet duct 6 is arranged on the front side of a cooling fan 7 of the automobile engine. The hot air emitted by the cooling fan 7 is used as an air source, so that the air conditioner is not required to heat, and the energy required by heating air is reduced.

In this embodiment, the air outlet 14b is provided with a second check valve 8, and the second check valve 8 is connected with the demisting air duct 9.

In this embodiment, a drying device 21, an electric heating device 22 and a temperature sensor 23 are sequentially disposed on the pipeline between the second check valve 8 and the defogging air duct 9. The drying device 21 is used for drying hot air, the electric heating device 22 is used for supplementing temperature when the temperature is insufficient, and the temperature sensor 23 is used for detecting the temperature.

In the present exemplary embodiment, the hydraulic system 4 is connected to a demisting switch 24. Hydraulic system 4

In the present embodiment, the one-way valve one 5 leads from the air inlet duct 6 to the air inlet 14a, and the one-way valve two 8 leads from the air outlet 14b to the demisting air duct 9.

In the present embodiment, the cam 3 has an elliptical boss structure. The working process and the principle thereof are as follows:

when a vehicle window is fogged, the demisting switch 24 is turned on, the cam 3 is driven by the hydraulic system 4 to slide on the main shaft 2, a spline shaft mode can be adopted, and the transmission and sliding functions are realized, because the cam 3 is an oval boss, the lowest point of the universal ball 15 is the highest point which is higher than the peripheral side of the small oval of the boss, the cam 3 is ensured not to collide with the universal ball 15, when the universal ball 15 at the bottom end of the piston 12 contacts the peripheral surface of the cam 3, the cam 3 rotates and moves rightwards at the same time, so that the piston 12 rod does reciprocating motion, and when the cam 3 moves to the right to reach a preset limit position, namely a normal working position, the universal ball 15 at the bottom of the piston 12 rod is positioned on the peripheral surface of the large oval and does reciprocating motion with the rotation.

The universal ball 15 is matched with the cam 3, so that the friction force is reduced, the abrasion is reduced, and the service life is prolonged.

When the cam 3 rotates to the level of the long axis of the ellipse, the spring 13 resets to enable the piston 12 to move downwards, the first check valve 5 of the air inlet 14a is conducted, hot air at the position of the engine cooling fan 7 passes through the air inlet duct 6 and is sucked into the liner 11 through the air vent 11a, then the cam 3 continues to rotate, the piston 12 moves upwards, the first check valve 5 of the air inlet 14a is closed, the hot air enters a cavity between the liner 11 and the shell 11b through the air vent 14, the air outlet 14b is communicated with the cavity, the second check valve 8 of the air outlet 14b is conducted at the moment, hot air is dried through the drying device 21, then the temperature is detected by the temperature sensor 23, an automobile computer compares the temperature with a preset value of required temperature, if the temperature is not enough, the electric heating device 22 is started for auxiliary heating, and finally the hot air is blown out of the.

Based on the above: when needing the defogging, hydraulic system 4 drive cam 3 moves to the right and utilizes car transmission system to drive main shaft 2 rotatory to drive cam 3 makes piston 12 up-and-down motion, realizes the function of original fan with the check valve cooperation again, and air inlet duct 6 of air supply subassembly 1 locates radiator fan 7 preceding, can make full use of radiator fan 7 department hot-blast like this, need not to open the air conditioner, reduces the oil consumption, has also avoided the compressor because of frequently opening the harm that brings of opening.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
