When the vehicle is parked, the main body 11 does not work any more, the first electromagnet 72 drives the rotating part bevel gear 31 to be meshed with the rotating shaft bevel gear 47, so as to drive the lifting connecting rod 49 to slide upwards through the rotating shaft 48, the reciprocating motor 41 is started to drive the lifting rod 42 to slide upwards synchronously through the screw 67, the lifting connecting rod 49 and the lifting rod 42 drive the spray head 43 to slide upwards, the first electromagnet 72 is started to drive the rotating part bevel gear 31 to be separated from the rotating shaft bevel gear 47, the spray head 43 is kept still in the exhaust cavity 21, clean water is injected into the hose 45 and sprayed into the exhaust cavity 21 through the water spraying hole 46, the reciprocating motor 41 continuously rotates forwards and backwards to drive the lifting rod 42 to ascend and descend, further, the spray head 43 is driven to rotate 720 degrees by taking the ball hinge 44 as a fulcrum, so that the cleaning work on the exhaust cavity 21 is better, and the piston 20.

After the cleaning is finished, the piston 20 is reset, the power motor 39 is started to drive the spray head 43 to reset, the sliding bevel gear 62 is separated from the power bevel gear 37, the reciprocating motor 41 is stopped, and the next work is waited.

The invention has the beneficial effects that: according to the invention, the temperature is sensed through the metal sheet in a mode of automatically adjusting the temperature in the three-way converter, so that the heating element and the piston are controlled to raise and lower the temperature in the exhaust cavity, the service life and the working efficiency of the three-way converter are prevented from being influenced by overhigh or overlow temperature in the three-way converter, and finally, the service life of the three-way converter is further prolonged through a parking cleaning mode, and meanwhile, the cost of manual cleaning is reduced.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
