As shown in fig. 1-4, when the device of the present invention is in the initial state, the toggle spring 13 and the control spring 27 are in the compressed state, the circulation chamber 28 and the ejection chamber 17 are not exactly corresponding, the right brush 31 is exactly partially located outside, and the paint storage chamber 60 stores the corresponding paint;

sequence of mechanical actions of the whole device:

when paint spraying is needed, high-pressure paint spraying equipment externally connected with the connecting pipe 11 works normally, high-pressure air and paint are sprayed into the spraying cavity 17 through the connecting pipe 11, the limit connecting block 24 is pressed, so that the limit connecting block 24 is completely positioned in the connecting cavity 25, at the moment, the deformation connecting block 22 generates certain deformation, a worker then moves the paint brushing main box body 54 to the right relative to the spray gun main body 10, the paint brushing main box body 54 drives the fixed connecting block 21, the deformation connecting block 22 and the limit connecting block 24 to the right through the installation connecting block 19, so that the paint brushing main box body 54 and the installation connecting block 19 are separated relative to the spray gun main body 10 and the spray head box body 18, at the moment, the poking rod 16 is poked to overcome the clockwise rotation of the spring 13, so that the poking pull rope 20 is loosened, the movable plug 12 loses the pulling force for poking the pull rope 20 and then slides, the corresponding areas of the circulation cavity 28 and the ejection cavity 17 change along with the rotation angle change of the poke rod 16, so that the paint spraying function of randomly adjusting the paint spraying amount is realized, and the working efficiency of painting is improved;

when corners or areas with complex shapes need to be painted, high-pressure paint spraying equipment externally connected with a connecting pipe 11 only sprays high-pressure air, the high-pressure air is sprayed into a spraying cavity 17 through the connecting pipe 11, the main painting box body 54 and the mounting connecting block 19 are kept to be matched with the spray gun main body 10 and the spray head box body 18, the poke rod 16 is pressed, so that the circulating cavity 28 and the spraying cavity 17 finally correspond to each other, the high-pressure air is sprayed into the wind power transmission cavity 56 through the circulating cavity 28 and the spraying cavity 17, the high-pressure air just can drive the impeller 33 to rotate at the moment, the high-pressure air is discharged through the secondary paint adsorption net 55, and the main paint adsorption net 34 and the secondary paint adsorption net 55 can adsorb residual paint in the high-pressure air, so that excessive paint is prevented from being adhered to the impeller 33;

the impeller 33 drives the wind power transmission shaft 49 to rotate, so as to drive the half straight gear 52 and the half bevel gear 51 to rotate, at the moment, the half bevel gear 51 is not just meshed with the conversion driven bevel gear 48, the half straight gear 52 is just meshed with the paint dipping driven gear 46, the half straight gear 52 drives the paint dipping driven gear 46 to rotate, so as to drive the paint dipping driving shaft 47 to rotate, the paint dipping driving shaft 47 drives the paint dipping main bevel gear 45 to rotate, so as to drive the paint dipping bevel gear 36 to rotate, the paint dipping gear 36 drives the paint dipping driven shaft 42 to rotate, so as to drive the water pump wheel 40 to rotate, the water pump wheel 40 just can suck the paint in the paint storage cavity 60 into the water pump cavity 37 through the paint absorption pipe 58 and the suction cavity 41, then the paint in the water pump cavity 37 is sprayed into the conversion cavity 29 through the discharge cavity 38 and the flow distribution plate 39, the flow distribution plate 39 can distribute the paint, so that the paint can be uniformly sprayed onto the brush 31 in the conversion cavity 29, so as to facilitate the subsequent painting work;

when the half straight gear 52 is disengaged from the paint dipping driven gear 46, the half bevel gear 51 is just engaged with the conversion driven bevel gear 48, the half bevel gear 51 drives the conversion driven bevel gear 48 to rotate, so as to drive the conversion driven shaft 43 to rotate, the conversion driven shaft 43 drives the conversion block 30 to overcome 63 rotation, 63 can prevent the inversion caused by the action of external force during painting, the conversion block 30 drives the brush 31 to rotate, and the brush 31 can just contact with the front end wall and the rear end wall of the conversion cavity 29 in the rotating process of the brush 31, so that the cleaning of redundant paint on the brush 31 is realized;

after the position of the brush 31 sprayed with paint is exchanged with that of the brush 31 not sprayed with paint, the wind power transmission shaft 49 rotates for a circle just, the circulation cavity 28 is separated from the corresponding spraying cavity 17 by loosening the poke rod 16, so that the brush 31 stops rotating, a worker can paint corners or areas with complicated shapes through the brush 31 at the moment, the spray gun and the brush are not required to be repeatedly and alternately used, and the working strength of the worker is reduced.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
