[0051] In addition, the liquid supply structure in the present invention includes a cleaning liquid pot 1; the cleaning liquid pot 1 is connected to the gas-liquid nozzle 10 through a liquid spray pump 3; in the present invention, the cleaning liquid pot 1 generally uses an existing vehicle-mounted cleaning chamber pot, that is, a pot body structure for storing traditional glass water.

[0052] The liquid spray pump 3 and the air pump 6 are both a power unit, which facilitates the liquid supply and air supply operations during use.

[0053] In the present invention, the air pump 6 is connected to the gas-liquid nozzle 10 through the air outlet pipe 7, and the spray pump 3 is connected to the gas-liquid nozzle 10 through the cleaning liquid outlet pipe 8; the setting of the air outlet pipe 7 and the cleaning liquid outlet pipe 8 facilitates the connection between the air pump 6 and the spray pump 3 and the gas-liquid nozzle 100.

[0063] In addition, as a greater optimization, in the present invention, when it is necessary to use gas and water at the same time, it is required to ventilate first and then ventilate the liquid. That is, after the air supply structure supplies air to the gas-liquid nozzle, the liquid supply structure is used to supply liquid to the gas-liquid nozzle. Based on such an operation sequence, the tilting efficiency can be guaranteed, because by using gas blowing first, the floating dust on the components can be removed first, and then water washing is performed, combined with gas flushing, so as to achieve a second flushing and cleaning of the components.

[0064] After a cleaning is completed, it is required to turn off the liquid first and then the gas. This operation method can enable the gas to purge the previous liquid and avoid water residue on the components.

[0075] Through the above operations, the vehicle-mounted component 11 can be cleaned.

[0076] Furthermore, in step 2 described in the present invention, it is required to first clean the component 11 to be cleaned by the liquid supply structure, and then blow dry the cleaned component 11 by the air supply structure; the present invention can clean the visual component 11 more quickly by first washing with water and then drying with gas, avoiding the problem that a single water liquid is easily contaminated with dust, and also avoiding the problem that a single gas blowing cannot achieve the problem of mud blocks sticking to the component 11 falling off.

[0077] Furthermore, in the present invention, the outer holes of the gas-liquid nozzle 100 are arranged to intersect with the component 11 to be cleaned; based on such a setting, it is generally required that the outer holes and the end face of the component 11 are arranged at an angle of 45 degrees. Such a setting can increase the contact area between the cleaning liquid, the gas and the component 11, and better achieve the falling of debris on the component 11.
