[Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. Referring to Figs. 5 and 6, the first preferred embodiment of the new type of high-adhesion, low-pollution airspace includes a spray gun body 2, an operation unit 3, and a nozzle cover 4. The spray gun body 2 includes a grab handle 21, a fuselage 22 formed on the grab handle 21, a spray head 23 formed on the fuselage 22, a nozzle 24 formed on the spray head 23, a A feed hole 25 formed on the body 22 and communicating with the nozzle, a majority of the vent hole 26 formed on the nozzle 23 and isolated from the nozzle 24, and a communication hole from the bottom of the grab handle 21 to The air passage 27 of the vent hole 26. The operation unit 3 is disposed on the spray grab body 2 and includes a thimble 31 penetrating through the body 22 and cooperating with the nozzle 24, and a thimble 31 arranged on the body 22 in cooperation with the thimble 31. A trigger 32, a piston member 33 provided in the air passage 27 in cooperation with the trigger 32, and a regulating valve rod 34 inserted in the air passage 27. The shower head cover 4 is disposed on the shower head 23, and includes a cover body 41 that cooperates with the shower head 23, and a penetrating communication with the nozzle 24 along the axial direction z of the cover body 41. The siphon hole 42 on the cover 41, four along the cover 20, M255079 41, _y one by one ^ radial Γ1 through the siphon holes 42 on both sides of the cover 41 on the lin #A forming The holes 43 and two are formed on the periphery of the cover 41 and located on the side of the 44 respectively, and the second spray forming holes 45 and two are respectively formed on the opposite sides of the columns 5 and 10 respectively. The _th limit hole 46 passing through the ends of the protrusions 44 and the second radial direction Γ2 of the cover 41 are passed through the suction holes of the cover 41 in the extending direction of the protrusions 44. The second limiting holes 47 on both sides, and a locking ring 48 surrounding the periphery of the cover 41. The first atomizing forming hole 43, the second atomizing forming hole 45, the first 4th hole 46 and the first limiting hole 47 are all isolated from the nozzle 24 on the spray head 23 and mutually communicate with the vent hole 26. Connected. The first radial direction rl and the second radial direction r2 are orthogonal to each other. The lock ring 48 is used to lock the nozzle cover 4 and the body 22 when the high adhesion and low pollution air spray paint is in a ready state. 15, the air duct 27 is in communication with an external high-pressure air pipe (not shown) to obtain high-pressure air input, and one end of the feeding hole 25 is connected to a tank (not shown) containing paint. Connected to get the required coating. At this time, the piston piece 33 cooperates with the surrounding wall surface to make the air passage 27 in a closed state. If the trigger 32 is pulled, the piston piece 33 will be pushed. The partition door 20 is opened, and the high-pressure air is allowed to reach the vent holes 26 along the communication path of the air passage 27, and then from the first atomizing forming holes 43, the second atomizing forming 孑 L 4 5, The first limiting holes 4 6 ′ and the second limiting holes 47 are sprayed outward. When high-pressure air is ejected from the first and second atomizing forming holes 43, 45, the rapidly flowing high-pressure air will cause M255079 negative reclamation around the siphon hole 42 and η Hai thimble 31 will be triggered by the trigger. The triggering of 32 causes the nozzle 24 to be opened at the same time, and then the paint in the tank is sucked out by a negative pressure, and a spraying effect is generated. 'When the paint is sprayed from the outside, The high-pressure air streams ejected from the two atomizing forming holes 43 and 45 are staggered with each other, and the paint can be sprayed to form finer paint particles, and the spraying area can be enlarged. ′ With reference to FIGS. 7 and 8, in addition to this, the high-pressure air flow in the first limit holes and the first limit holes 47 will be sprayed out simultaneously with the travel of the paint, and sprayed and atomized. An air hood 形成 is formed around to prevent the paint from being blocked by the air hood 咼 while traveling at a high speed, and it is not easy to fly to the outside of the air hood Η, so that most of the paint is attached to an effective coating. In the cloth area A, the high-pressure airflow sprayed from the first limiting holes 46 can limit the overall width of the effective coating area A, and the high-pressure airflow sprayed from the second limiting holes 46 can limit the effective coating. The entire length of the cloth area A, so the range of an invalid coating area B formed by diffusion around the effective coating area A along a diffusion distance D is also reduced, and with the above-mentioned composition structure, when the siphon hole 42 The higher the air pressure, the higher the high pressure air flow from the first limit holes and the second limit hole 47, so even when the output pressure is increased to increase the atomization effect, , Can still be relatively high output pressure Η of the air cap to prevent scattering of the coating, the coating can be so attached to the active focus region Α coating so that the coating effectively utilized. Summarizing the above-mentioned 'the new surface adhesion, low pollution air spray paint grab is the principle of forming the air hood using high pressure air flow to prevent paint from scattering, and M255079 5 10 15 20 and through these first limit holes 46 and the first The high-pressure air flow ejected from the two limiting holes 47 generates the air hood to achieve a specific effect, so the atomized paint will be limited to the area defined by the air hood and will not easily scatter outward. Therefore, the paint can be concentrated in the effective coating area A and the two-gas pollution can be reduced, and the paint can be maintained in a state of better atomization effect when sprayed out. Therefore, it can meet the aesthetic requirements of general paint, and it is true The main purpose of this new type of high adhesion and low pollution air spray paint can be achieved. However, the above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new application and the contents of the new specification. , All should still fall within the scope of this new patent.
