V. Creation Instructions (l) [Technical Field to which the New Type belongs] This creation relates to the improvement of a spray gun structure, especially a new type of spray gun structure that can be applied to more detailed spraying and has no dead angle when used. Prior art] As the spray gun of the way is sprayed, it is used to depict the layout lines on it. The structure of the art spray gun has been shown in the attachment, and it is held on the rear handle (20), and sprayed out. This kind of posture is disadvantageous to the problem that the movement is not smooth. ) The high-pressure gas generated material is sprayed through the nozzle (50). The sprayed pigment is no longer concentrated by the nozzle. According to the art, the spray gun is a kind of paint used for art to connect the air pressure from the air pressure driving source to the pigment color. It is very fast and convenient, and can be gradually accepted by general practitioners for general use. It is known as disclosed in National Patent Gazette No. 52288 1 (the following problems still exist in international applications: 1. The art spray gun is holding When the hand presses the pressure handle (1 3) with the thumb, the pigment can be sprayed on the artist. When in use, there will be 2. The artist spray robs the spray head by the vacuum suction of the spray head (40. The inner mouth (511) of the tank (60) is sprayed, but the spray (40) is concentrated from the spray port (511), and the sprayed pigment will not be able to perform detailed spraying. 3. The spray tank ( 60) It is formed at the bottom end of the spray grab main body (10). When the spray position of the user is higher than the eyes, when the artist spray is lifted up and used, the spray can (60) will block the user's sight , The user will not see the spraying condition of the nozzle (40). With the use of Q ^ dead point. [SUMMARY] ~

M242299 V. Creative Instructions (3) First, please refer to Figures 1, 2, 3, and 4 for a better example of the structure improvement of the creative artist's spray gun. Its large system consists of a spray gun body (10), A needle valve (20), a cup (30), a nozzle (40), a pressure handle (50), characterized in that: the spray gun body (1 0) is a hollow tube body, The front end is assembled with a nozzle (11), a nozzle sleeve (12) is sleeved on the outside of the nozzle (11), and a valve hole (丨 3) is provided on the rear end surface of the spray gun body (1 0), and the valve hole ( ] 3) communicate with the nozzle (11) to form a lateral air channel. The top end mask behind the nozzle (Η) has a convexly inclined assembly (14) and is close to the rear section of the spray gun body (10). The top surface is provided with a socket (15), and the bottom end surface of the rear section of the spray gun body (10) extends a length of a grip (16). The grip (1 6) is hollowly connected to the socket (1 5). The needle valve (20) is a valve body for controlling air flow, which is composed of a needle seat (2J) and a needle rod (22). The needle rod (22) is pivotally arranged in the horizontal direction. Spirit In the middle, one end is a central end, so that the nozzle (I) can be plugged, and the other end of the needle bar (2 2) is fixed to the inside of the needle seat (2 1) in a pin setting manner, and the needle The outer front end of the seat (21) has a section of external thread (23) and the lock set is in the valve hole (1 3); the outer cup (30) is curved and the top is provided with an openable cup lid (31) The bottom group is connected to the main body (10) of the spray gun (14); 'The connecting pipe (40) is connected to the bottom end of the handle (16), and the interior is hollow to form a piston airway (41) structure , And the piston airway (41

M242299 V. Creative Instructions (4)) There are two air passages with different flow paths. The upper air passage (42) has a smaller flow path. The lower air passage (4 3) has a larger flow path and the upper air path. (4 2) The branches on both sides near the top form a vent hole (44), and the outlet of the vent hole (44) is formed on the top surface of the connecting pipe (40) and is parallel to the exit of the piston airway (41). A piston rod (42) is pivotally arranged inside the piston airway (41) 'the top of the rod (4 5) protrudes a considerable length from the top surface of the nozzle (40)' and the long end of the rod (45) is directed to the middle section A top surface of the piston portion (46) is provided to cover the joint end surfaces of the upper (42) and lower air passages (43) to block the air flow, and a screw is formed at the bottom of the lower air passage (42). Piece (4 7), the bottom of the pressing rod (4 5) is pivoted in the screw piece (4 7), and a force element (4 9) is provided between the screw piece (47) and the piston part (46) ) 'When the pressure rod (4 5) is not depressed by external force, the top surface of the piston portion (46) is covered by the tension element (48) to cover the upper (42) and lower airway (43) Joint face The pressing handle (50) is inserted into the insertion hole (丨 5), a pressing portion (51) is formed at the top end, and a driving handle (52) of an appropriate length is extended from the bottom end surface of the pressing portion (51). After the handle (52) is first formed to be spaced to bypass the needle bar (2 2), the bottom end of the handle (52) abuts against the top of the pressure rod (50); by virtue of the above-mentioned components, the bottom end of the pipe (40) is connected to connect The air pressure from the air pressure driving source (as shown in FIG. 5), when the user presses the pressing part (51), the driving handle (5 2) presses down the pressure rod (50), and the piston part (46 ) Uncovered at the joint end faces of the upper (42) and lower half airways (43), so that the upper half (42) and the lower half (43) communicate with each other, and the air pressure is ejected from the vent (44) through the nozzle (40) and spray gun body (1〇)

Page 7 M242299 V. The airway of the creative instructions (5) 'Finally spray the pigment from the nozzle ⑴), and then rotate the needle valve (20) and the nozzle sleeve (12) to control the amount and shape of the pigment, respectively, to form a practical Convenience. With this, the overall formation structure of the creative artist's spray gun has a posture like holding a gun when holding, which makes the hand movement smoother during spraying, and it is convenient to use, and the tapered nozzle (11) cooperates with the nozzle sleeve. (12) The design allows the pigment to converge, which will be more concentrated when spraying, and can perform more detailed spraying work. 'Simulating cup (30) $ 成 于 Spray the main end of the main body (10) * user The spraying position is close to the eyes, and when the artist sprays it up, the time: the cup (30) + will block the user's line of sight, the user still: see the spraying condition of the nozzle, forming no dead angle when using Advantages. [Effect description] The facts that this creative effect is enhanced are as follows: ig ^ μ # The overall formation structure of ϋ Zuo art spraying, when held, it is like layer 9: ί, which makes the hand movement smoother and easier to use during spraying. The painting volume is sprayed with a cone-shaped nozzle (11) and the spray 4 # 隹 * sigh leaf makes the pigment converge in the nozzle. During spraying, a finer spray can be performed. Tu work. ] η, the creative cup of art spraying (30) created from the book is formed on the main body of the spraying (the spraying and spraying is 5 sides' when the user sprays the position higher than the eyes', it will be beautiful when using f, ' The cup (30) will not block the user ’s sight. It can be seen that the spraying of the nozzle 'forms no dead angle when used.
