When the switch is turned on, the compressed air atomizes the paint in the paint pot 2 into fine paint droplets, which are sprayed onto the surface of the car body through the paint spraying tube 3 to complete the painting operation. The specific spraying principle and operation steps are not repeated here, and also include:

[0043] A protective cover 5, which is arranged on the paint spraying tube 3;

[0044] An air outlet pipe 6, wherein a plurality of air outlet pipes 6 are provided, and the plurality of air outlet pipes 6 are all provided on the protective cover 5;

[0045] A circulation mechanism 7, used for controlling a plurality of air outlet pipes 6 to form an airflow on the shield 5, and arranged between the paint spraying pipe 3 and the shield 5;

[0046] The deformation mechanism 8 is used to drive the shield 5 to change its shape and provide dust protection in the sweep spraying and surrounding spraying modes, and is arranged on the shield 5;

[0047] The switching mechanism 9 is used to drive the deformation mechanism 8 to operate when the adjustment head 4 rotates to switch between the sweeping spraying mode and the surrounding spraying mode, and is arranged on the paint spraying tube 3.

[0048] The circulation mechanism 7 comprises a first ring seat 71 arranged on the paint spraying tube 3, the middle part of the first ring seat 71 is a cavity, a second ring seat 72 is arranged on the paint spraying tube 3, and the shield 5 is arranged on the second ring seat 72; the compressed gas is transferred in the cavity.

[0049] The first ring seat 71 is provided with a flow guide assembly 10 for realizing gas circulation between the first ring seat 71 and the plurality of air outlet pipes 6; the flow guide assembly 10 comprises an air inlet pipe 101 provided on the first ring seat 71, a plurality of air outlet pipes 6 are provided with a deformable tube 102 at one end, the plurality of deformable tubes 102 are connected to the first ring seat 71, a plurality of air outlet pipes 6 are provided with a plurality of air holes 103, a plurality of connecting strips 104 are provided on the shield 5, a plurality of limiting plates 105 are provided on the plurality of connecting strips 104, and the air outlet pipes 6 are fixed to the shield 5 through the corresponding connecting strips 104 after passing through the plurality of limiting plates 105; the air inlet pipe 101 is also connected to the air pressure The compressor is connected, and the compressed air enters the first ring seat 71 from the air inlet pipe 101, passes through the deformation tube 102, and is ejected from the multiple air holes 103 on the air outlet pipe 6, forming an airflow around the shield 5 to blow away the dust on one side of the shield 5 to prevent the dust from reaching the other side, thereby performing dust protection; the deformation tube 102 can maintain the connection with the first ring seat 71 during the deformation process to adapt to the shape change of the shield 5; the connecting strip 104 and the multiple limit plates 105 connect and fix the air outlet pipe 6 to the shield 5, and a Velcro structure can be set between the connecting strip 104 and the shield 5 to ensure the connection and fixing effect while facilitating subsequent cleaning and disassembly.

[0050] The deformation mechanism 8 includes four connecting plates 81 arranged on the protective cover 5, two transition plates 82 are arranged on the second ring seat 72, and two pull ropes 83 are arranged on the two transition plates 82. The two pull ropes 83 on the same side are respectively connected to the two connecting plates 81 on the same side; the protective cover 5 can be made of ABS material and changes its shape when subjected to external force; pulling the pull rope 83 drives the connecting plate 81 to deflect, thereby driving the protective cover 5 to change its shape, so as to protect the paint spray tube 3 from dust in the two modes of sweeping spraying and surrounding spraying.

[0051] The pull rope 83 is made of platinum-rhodium alloy; the platinum-rhodium alloy has good oxidation resistance and corrosion resistance, and is not easy to extend when subjected to axial pulling, thereby ensuring the effective connection between the pull rope 83 and the connecting plate 81 and maintaining the transmission distance, thereby increasing the service life.

[0052] The switching mechanism 9 includes a mounting seat 91 arranged on the paint spraying tube 3 .

[0053] A displacement assembly 11 is provided on the mounting seat 91, which is used to pull the four pull ropes 83 to move; the displacement assembly 11 includes a displacement plate 111 slidably arranged on the mounting seat 91, one end of the two pull ropes 83 on the same side are combined into one strand and then connected to the displacement plate 111, a convex plate 112 is provided on the displacement plate 111, and a spring 113 is provided between the convex plate 112 and the mounting seat 91; the displacement of the displacement plate 111 pulls the pull rope 83 to move; a protruding structure can be provided on the paint spray tube 3, and the pull rope 83 passes through the protruding structure, which plays a limiting role on the pull rope 83 and avoids the pull rope 83 from being messy; after the external force is removed, the spring 113 assists the displacement plate 111 to reset, thereby restoring the shield 5.

[0054] A linkage assembly 12 is provided on the adjusting head 4, which is used to drive the displacement plate 111 to move when the adjusting head 4 rotates; the linkage assembly 12 includes a rotating inclined block 121 provided on the adjusting head 4, and a displacement inclined block 122 is provided on the displacement plate 111, and the displacement inclined block 122 is in contact with and fits with the rotating inclined block 121; the rotation of the adjusting head 4 drives the rotating inclined block 121 to deflect, and the rotating inclined block 121 pushes the displacement inclined block 122 to drive the displacement plate 111 to move.

[0055] A limiting member 13 is provided on the adjusting head 4 for limiting the position of the adjusting head 4; the limiting member 13 comprises a connecting seat 131 provided on the adjusting head 4, a limiting rod 132 is provided on the connecting seat 131, a pulling plate 133 is provided on the limiting rod 132, and a connecting seat 134 corresponding to the limiting rod 132 is provided on the paint spray tube 3; the adjusting head 4 rotates to drive the rotating inclined block 121 and the connecting seat 131 to rotate, and the connecting seat 131 is aligned with the connecting seat 134 after rotation, and the pulling plate 133 is pushed to drive the limiting rod 132 to engage with the connecting seat 134, thereby limiting the position of the adjusting head 4, avoiding it from being reset at will due to the elastic force of the spring 113 and the stress of the elastic deformation of the shield 5, and ensuring the stability of the overall structure; a convex piece structure can be provided on the limiting rod 132 to limit the limiting rod 132 and avoid it from being separated from the connecting seat 131 when pulling back, so that the pushing and pulling distance of the limiting rod 132 is controllable.

[0056] When in use, the air inlet pipe 101 is connected to the air compressor, and the compressed air enters the first ring seat 71 from the air inlet pipe 101, passes through the deformation tube 102, and is ejected from the multiple air holes 103 on the air outlet pipe 6, forming an airflow around the protective cover 5, blowing away the dust on one side of the protective cover 5 to prevent the dust from reaching the other side, thereby providing dust protection.

[0057] When the adjusting head 4 is rotated to switch between the sweeping spraying and surrounding spraying modes, the adjusting head 4 rotates to drive the rotating bevel block 121 and the connecting seat 131 to rotate. After the connecting seat 131 rotates, it is aligned with the connecting seat 134, and the pull plate 133 is pushed to drive the limit rod 132 to engage with the connecting seat 134, thereby realizing the position limitation of the adjusting head 4. In this process, the rotating bevel block 121 deflects and pushes the displacement bevel block 122 to drive the displacement plate 111 to move. The displacement of the displacement plate 111 pulls the pull rope 83 to move. The pull rope 83 drives the connecting plate 81 to shift, thereby driving the protective cover 5 to change its shape, so as to provide dust protection for the paint spray tube 3 in both the sweeping spraying and surrounding spraying modes.

[0058] Example 2: Please refer to Fig.13 , the present invention provides a technical solution:

[0059] Different from Example 1, the pull rope 83 is divided into two sections, and a connecting column 14 is provided at one end of the two sections of the pull rope 83. A screw 15 is provided on one connecting column 14, and the two connecting columns 14 are connected by the screw 15; after long-term use, due to the change in the performance of the structures such as the shield 5 and the spring 113, the transmission distance of the pull rope 83 changes; the two connecting columns 14 are connected by the screw 15, which can change the distance between the two sections of the pull rope 83, thereby changing and calibrating the transmission distance to ensure effective deformation protection of the shield 5.
