DETAILED DESCRIPTION

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a spray gun with an easily adjustable spray head comprises a gun body 1, a spray head 2, a spray head 3, a docking disc 4, a spray mounting cover 5 and a synchronous cover 6. The spray head 2 is arranged on one side of the gun body 1, and further comprises a spray head 3, a docking disc 4, a spray mounting cover 5 and a synchronous cover 6. The docking disc 4, the spray head 3 and the spray mounting cover 5 are sequentially arranged on one side of the gun body 1 close to the spray head 2. The spray mounting cover 5 is fixedly mounted on the gun body 1 and limits the docking disc 4 and the spray head 3 on the gun body 1. The synchronous cover 6 is fixedly mounted on the outer side wall of the spray head 3. A synchronous notch 31 is provided on the spray head 3. The synchronous notch 3 1 is located on the outer side of the end surface of the spray mounting cover 5, a synchronous locking groove 32 is provided on the corner of the spray head 3 away from the docking disc 4, a penetrating central through-slot 61 is provided in the middle of the synchronous cover 6, a synchronous protrusion 62 that fits with the synchronous notch 31 is provided on the central through-slot 61, and a synchronous locking piece 63 that fits with the synchronous locking groove 32 is provided on the central through-slot 61. Rotating the synchronous cover 6 drives the spray head 3 to rotate synchronously, wherein the spray head 3 and the synchronous cover 6 can be flexibly rotated at the nozzle 2 of the gun body 1, and the docking disc 4 is relatively stationary and fixed at the nozzle 2 of the gun body 1 for docking the spray head 3 with the nozzle 2;

[0025] The rotation of the spray head 3 in this solution can adjust the spray state of the spray gun, which is the same as the Chinese utility model patent with publication number CN201644270U in the prior art, and can change the mist shape by rotating the spray head 3.

[0026] In some embodiments, four synchronization notches 31 are provided, and the four synchronization notches 31 are arranged in a circle at the corners of the spray head 3 away from the docking disk 4. Four synchronization protrusions 62 are provided, and the four synchronization protrusions 62 respectively fit with the four synchronization notches 31. In this way, the power of the spray head 3 and the synchronization cover 6 can be uniformly transmitted through the mutual cooperation of multiple synchronization notches 31 and synchronization protrusions 62.

[0027] In some embodiments, a protruding spray bump 7 is provided on the side of the spray head 3 away from the docking disc 4. The spray bump 7 can realize spray gun spraying. At the same time, the user can also drive the entire spray head 3 to rotate by rotating the spray bump 7 to adjust the spray shape and state. On this basis, a fitting groove 64 that fits with the spray bump 7 is provided at the middle through groove 61 of the synchronous cover 6. The mutual cooperation between the spray bump 7 and the fitting groove 64 can further improve the power transmission stability of the spray head 3 and the synchronous cover 6.

[0028] In some embodiments, a rotating portion 51 is provided on the side of the spray mounting cover 5 away from the gun body 1, and a rotating cylinder 65 is provided on the synchronous cover 6. The inner wall of the rotating cylinder 65 slides with the outer wall of the spray mounting cover 5. The setting of the rotating portion 51 and the rotating cylinder 65 can improve the rotational stability of the synchronous cover 6 on the spray mounting cover 5. It can be imagined that the diameter of the rotating portion 51 is smaller than the diameter of other parts of the spray mounting cover 5. At this time, the synchronous cover 6 is mounted on the rotating portion 51 to make the overall spray gun structure more coordinated and stable.

[0029] In some embodiments, an arc-shaped groove 651 is provided around the outer wall of the rotating cylinder 65. The arc-shaped groove 651 can facilitate the user to hold and rotate the rotating cylinder 65 with his hands, thereby increasing the contact area between the user's hands and the rotating cylinder 65, so that the user can hold the outer wall of the rotating cylinder 65 and rotate the integral synchronous cover 6 and the spray head 3.

[0030] In some embodiments, a docking seat 8 is provided on the side of the spray head 3 close to the docking disc 4, and an elastic portion 81 is provided on the docking seat 8. A docking protrusion 82 is provided on the elastic portion 81 close to the docking disc 4. A plurality of docking grooves 41 are evenly spaced around the side of the docking disc 4 close to the docking seat 8. The elastic portion 81 pushes the docking protrusion 82 to fit into the docking groove 41, and the docking protrusion 82 fits into any docking groove 41. When the spray head 3 is adjusted, the docking protrusion 82 and the docking groove 41 at any corresponding position cooperate with each other to achieve the fixation of the spray head 3, thereby preventing the spray head 3 from rotating without human operation and affecting the spray effect.

[0031] In some embodiments, the elastic portion 81 is arranged in a V-shape, and the docking protrusion 82 is arranged in the bending area of the elastic portion 81. During the rotation of the spray head 3, the docking protrusion 82 moves out of one of the docking grooves 41. At this time, the V-shaped elastic portion 81 bends and deforms and generates elastic potential energy. When the docking protrusion 82 moves to the docking groove 41 at the next corresponding position, the V-shaped elastic portion 81 is reset and drives the docking protrusion 82 to move to the docking groove 41 for fixation. When the user controls the spray head 3 to continuously adjust, the above action is repeated until it is in an appropriate state.

[0032] In some embodiments, a disc groove 42 is provided on the side of the docking disc 4 close to the gun body 1, and a protrusion that fits with the disc groove 42 is provided in the gun body 1. The docking circle can be fixed by the disc groove 42 and the protrusion provided on the gun body 1, preventing the docking circle from rotating during use and affecting the structural stability of the spray gun.

[0033] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the claims of the present invention.
