[0002] The car air dryer is an indispensable part of the car, especially some heavy-duty cars. Its function is to dry the compressed air from the car's air pump so that the moisture contained in the gas will not enter the car's braking system through the gas, thereby keeping the car's braking system sensitive and effective.

[0003] According to a car air dryer disclosed in the patent with patent number CN210278741 U, the patent can effectively avoid the shaking of the drying cylinder when the air dryer is installed horizontally on the car, enhance the use stability of the air dryer, and improve the practicality of the car air dryer. In actual application, water will remain inside the car air dryer after use, and the valve inside the car air dryer will be easily frostbitten in cold weather. At the same time, when the desiccant absorbs more water, it needs to be replaced, which will increase the economic pressure of the car owner. At the same time, the air entering the car air dryer contains a large amount of impurities. After long-term use, the impurities will contaminate the desiccant inside the drying tank and reduce the efficiency of the car air dryer in drying the air. To this end, we provide a car air dryer to solve the above problems. Utility Model Content

[0026] Four support columns 11 are fixedly connected to the inner bottom wall of the shell 2, and the top ends of the four support columns 11 are fixedly connected to the bottom surface of the drying tank 4. The support columns 11 can support the drying tank 4 and effectively increase the stability of the drying tank 4.

The flow of air can drive the activated carbon filter plate 701 to slide. The guide rod 703 can limit the activated carbon filter plate 701, and can prevent the activated carbon filter plate 701 from shifting when sliding, which can increase the stability of the device during operation. The elastic force generated by the deformation of the telescopic spring 704 can drive the activated carbon filter plate 701 to automatically reset.

[0030] The top end of each guide rod 703 is fixedly connected to a limiting disk 12, and the diameter of the limiting disk 12 is greater than the diameter of the guide rod 703. The limiting disk 12 can limit the activated carbon filter plate 701, which can effectively prevent the activated carbon filter plate 701 from falling off the guide rod 703, and can effectively increase the safety of the device.

The heating wire 8 is controlled by a controller. When the heating temperature exceeds 80°C, the sensor controls the heating wire 8 to stop working to prevent the high temperature from affecting the device. The steam can be discharged through the outlet pipe 9 to prevent the steam from re-condensing into water droplets. The one-way valve 10 can prevent air from entering the device from the outlet pipe 9.

[0036] The front end of the mounting bolt 19 is fixedly connected with a nut 20, and the outer surface of the mounting bolt 19 is sleeved with a washer 21. The nut 20 can make it more convenient for the staff to rotate the mounting bolt 19, and the washer 21 can reduce the wear of the mounting frame 18 caused by the rotation of the nut 20.

[0037] Working principle: When using the device, it is first necessary to install it on the car, and then connect the pipe to the connection on the base 1. The air enters the interior of the housing 2 through the air inlet 3, and then the air passes through the activated carbon filter plate 701. The activated carbon filter plate 701 can adsorb and filter the air. The flowing air can drive the activated carbon filter plate 701 to move, and then drive the telescopic spring 704 to deform. The elastic force generated by the deformation of the telescopic spring 704 can push the activated carbon filter plate 701 to rise, and then the activated carbon filter plate 701 can shake. , which can make the activated carbon filter plate 701 have a better adsorption and filtration effect on the air, and then the dried air will be transported to the outside through the sealing tube 6. When the device stops running, the electric heating wire 8 can be started. The desiccant inside the drying tank 4 can be dried by the electric heating wire 8, which can reduce the moisture contained in the desiccant, so as to ensure the drying efficiency of the device for the air. When the electric heating wire 8 is heated to 80°C, the controller controls the electric heating wire 8 to stop working, and the steam generated during drying can be discharged through the outlet pipe 9. The one-way valve 10 can prevent air from entering the interior of the device through the outlet pipe 9.
