At the same time, the periphery of the retaining ring (62) is provided with A communication hole (621) is connected to the sine drainage channel (614). When assembling, the feeding tube (60) is inserted into the main shaft (32) through the pivot hole (161) of the cover body (16) through its tube body (61) 15 and then a plurality of screws (63) The retaining ring (62) is locked to the outside of the cover (16), so that the convex portion (613) of the pipe body (61) can extend into the cover (16) and the air distribution plate (50) between. The spray head (70) has a cup shape in this embodiment, and has a large-diameter open end (71) and a small-diameter connection end (72), and the peripheral surface within the connection end (72) is 20 It has an internally threaded section (721); secondly, the nozzle (70) has a turbine section (73), which is composed of a plurality of blades (731) in a radial circle, and The blade (731) is inclined in the same rotation direction. The center of the end surface of the turbine portion (73) facing the connection end (72) has a convex portion (732), and a recessed hole is recessed from the center of the other end surface ( 733), which is used for installing the insert (81) of a diffuser plate-8-M264019 (80). Since the diffuser plate (80) is a conventional component, it will not be described in detail. Referring to the sixth to eighth drawings, the air-floating spray grab (1) of this creation is connected with a paint conveying pipe before the feed inlet (611) of the feed pipe (60) (5 in the picture). (Shown) 'respectively in the communication hole (621) of the retaining ring (62), the air inlet (162) of the cover (16), the air inlet (1211) of the air nozzle (12), and the body (14 A high-pressure air pipe (not shown) is connected to each of the air inlets (142). As shown in the sixth figure, at this time, the high-pressure air entering from the air inlet (142) of the body (14) will flow out of the communication hole (144) and the air-floating assembly (30) H), respectively. The high pressure air flowing into the air passages (311) of the tube (31) and flowing into the air passages (311) is then channeled through its through hole (312) to push the main shaft (32) to push the main shaft (32). ) Is thus suspended in the outer tube (31); refer to the seventh figure, however, after the local pressure air pushes against the main shaft (32), it will follow the distance between the outer tube (31) and the main shaft (32). The slits flow around, and pushing the tabs (321) 15 of the main shaft (32), causing the main shaft (32) to shift outward. To avoid the tabs (321) of the main shaft (32) and the second The contact of the ring (44) generates friction, so that the high-pressure air that has entered the communication hole (144) will pass through the perforation (21) of the inner ring (20) and the guide of the first ring (42). The hole (421) flows into the flow channel (442) through the through hole (441) of the second ring (44), and the inner and outer airtight ring 20 (46j) of the third ring (46) ) (463) 's barrier' causes Gao Mo air to be forced to peep into the second ring (4 sentences: air hole (443), so a counter Push the tab ⑽ of the main shaft ⑽) ^ to balance the main shaft ㈤, _, the relationship between the two front and back air currents generating dust due to mutual conflict will be blown out of the air hole (422) of the _ ring (42) , And then discharged through the exhaust hole (143) of the body (14). Secondly, as shown in Figure 8-9-M264019, the high-pressure air entering from the air inlet (162) of the cover (16) will initially accumulate between the cover (16) and the air distribution plate (50). In the air chamber (54) under pressure, the high-pressure air will penetrate into the through hole (52) of the air dividing plate (50) to form an airflow with a predetermined rotation direction, and then pass through the turbine (33). 5) of blades (333), thereby forming a more uniform thrust force, driving the main shaft (32) of the air-floating component (30) to rotate at a high speed relative to the outer tube (31), and high-pressure air passing through the turbine (33 ), The blade (333) will be naturally discharged from the exhaust hole (143) of the body (14). As shown in the ninth figure, the high-pressure air input from the communication hole (621) of the retaining ring (62) will follow both the cover (16), the air distribution plate (50) and the The gap between the pipe body (61) of the 10 feeding pipe (60) penetrates into the turbine (33) and the main shaft (32) of the air-floating component (30), and finally, along the nozzle ( 7〇) The inner wall surface is led out to remove the paint adhering to the surface of the nozzle (70), so as to achieve the effect of self-cleaning. With this, the air-floating spray gun of this creation, when the main shaft is rotated, is driven by 15 high-pressure air without friction with any component. Therefore, the problem of frictionless heat generation is generated. Therefore, paint spraying There will be no fatigue particles when coated on the surface of the processed part, so that the processed part with a flat coating surface can be obtained. Secondly, because there is no wear, the number of spray gun repairs and maintenance is reduced, and its service life is extended. Furthermore, there is no friction, so that the main shaft can drive the spray head 20 and the diffuser plate to rotate more quickly, thereby improving the spray atomizing effect of the coating, making the coating adhere to the high efficiency and obtaining a more even coating. surface. In addition, as shown in the tenth figure, the high-pressure air entering from the air inlet (1211) of the air nozzle (12) will be led out from the air gap (127), thereby forming an annular air wall, so that after atomization The paint is less likely to escape from the spray area. Therefore, it can avoid wasting paint. In addition, the main purpose of this creation is to increase the relative rotation between the inner and outer tubes, so that the paint can be atomized into finer molecules after passing through the nozzle. Therefore, without the diffusion plate, the purpose of atomizing the paint can still be achieved. 5 Finally, it is added that when the angle between the nozzle blade and the mandrel of the pipe body is between 45 ° and 89 °, the spray coating can obtain the best coating atomization effect. -11- M264019 15 [Brief description of the drawings] is the standpoint of the preferred embodiment of this creation.
