[0033] The paint conduit 120 is inserted into the support tube 110 and fixedly connected to it. Multiple nozzles 121 are provided on the paint conduit 120. Each nozzle 121 passes through the peripheral wall of the support tube 110, extending from the inside to the outside of the support tube 110, and is arranged sequentially along the length of the support tube 110. Each numbered tube 130 corresponds to one nozzle 121, and the nozzle 121 abuts against the connector 132. The spray head 100 can be used on various types of spray guns. In use, paint enters from the inlet end of the paint conduit 120 and then fills the paint conduit 120. The nozzles 121 can adopt existing nozzle structures.

[0034] Preferably, a pressure valve is provided at the nozzle 121. When pressure is applied by the spray gun, the pressure valve is opened, and paint is sprayed out. The pressure valve is used to prevent paint from leaking from the nozzle 100.

[0035] After the paint is sprayed from the nozzle 121, it enters the connector 132 and then exits from the numbering hole 131. Preferably, the connector 132 is made of an elastic sealing material such as silicone, and an annular sealing ring is also provided at the outlet of the nozzle 121; the connector 132 is embedded in the outlet end of the nozzle 121, making the connection tighter. When the numbering tube 130 is rotated, the elastic connector 132 can easily disengage from the cavity, and the next elastic connector 132 can easily be embedded into the cavity.

[0036] Please see Figure 1 In one embodiment, the inlet end of the paint conduit 120 is provided with a connecting structure 122 for connecting to a spray gun. By providing the connecting structure 122, the spray head 100 can be adapted to different spray guns. The connecting structure 122 can be a snap-fit ​​connection structure or a threaded connection structure.

[0037] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the support tube 110 is provided with multiple sets of guide structures; each guide structure includes two parallel guide rails 111, which extend circumferentially along the outer peripheral wall of the support tube 110; the numbering tube 130 is sleeved on the two guide rails 111 and rotatably connected to them. Specifically, the two guide rails 111 are fixedly connected. Specifically, the nozzle 121 and the connector 132 are both located between the two guide rails 111, and are not obstructed by the guide rails 111 when the numbering tube 130 is rotated.

[0038] Please see Figure 2In one embodiment, the support tube 110 is provided with a groove 112 and a slot, which extend along the length of the support tube 110. The guide structure slides along the groove 112 on the support tube 110. Multiple nozzles 121 are disposed on the slots and connected to the paint pipe 120 via movable tubes 123, the length of which is greater than the shortest distance from the paint pipe 120 to the nozzle 121. The nozzles 121 are fixedly connected to the guide structure. In this embodiment, the positions of the guide structure and the nozzles 121 can be finely adjusted, thereby changing the distance between two adjacent numbered tubes 130. Specifically, the movable tube 123 is a flexible tube. By providing the movable tube 123, the relative positions of the nozzles 121 and the paint pipe 120 can be adjusted. When the guide structure moves, it causes the nozzles 121 to move as well. In this embodiment, a slider is provided at the bottom of the guide rail 111, and the slider is disposed within the groove 112.

[0039] Please see Figure 1 , Figure 3 and Figure 4 In one embodiment, the inner circumferential wall of the numbering tube 130 is provided with a plurality of elastic locking structures 133; the outer circumferential wall of the guide rail 111 is provided with a ring groove 124, and a plurality of arc-shaped protrusions 125 are provided at equal intervals in the inner circumferential direction of the ring groove 124; a locking position is formed between two adjacent arc-shaped protrusions 125; the elastic locking structure 133 engages with the locking position. In this embodiment, two elastic locking structures 133 are provided. When the numbering tube 130 is rotated, the elastic locking structure 133 moves along the arc-shaped protrusions 125. At this time, the elastic locking structure 133 is compressed. When the elastic locking structure 133 passes an arc-shaped protrusion 125, the elastic locking structure 133 rebounds and is embedded in the next locking position, and the numbering tube 130 is fixed.

[0040] Please see Figure 3 In one embodiment, the elastic locking structure 133 includes an elastic element 1331 and an arc-shaped locking block 1332. The two ends of the elastic element 1331 are fixedly connected to the inner peripheral wall of the numbering tube 130 and the arc-shaped locking block 1332, respectively. Preferably, the elastic element 1331 is a spring. The arc surface of the arc-shaped locking block 1332 faces the annular groove 124, and when paired with the arc-shaped protrusion 125, it allows for smoother rotation of the numbering tube 130.

[0041] Please see Figure 5In one embodiment, the numbering tube 130 includes multiple first numbering pieces 134 and two rotating rings 135.

Each first numbering piece 134 can be replaced at any time according to usage needs, making it suitable for more different numbering requirements, such as combinations of letters and multiple digits, or combinations of multiple letters and multiple digits. The shape of the numbering hole 131 on the first numbering piece 134 can be designed in advance according to requirements.

[0042] Please see Figure 6 In one embodiment, the numbering tube 130 consists of a numbering strip 136 detachably connected end-to-end and two rotating rings 135; the numbering strip 136 is detachably connected to the two rotating rings 135; the numbering strip 136 includes multiple second numbering pieces 1361, with adjacent second numbering pieces 1361 hinged to each other. In this embodiment, the multiple second numbering pieces 1361 form the numbering strip 136, requiring the entire numbering strip 136 to be replaced during replacement, which has the advantage of more secure fixation of the second numbering pieces 1361. After the numbering strip 136 is installed on the two rotating rings 135, the second numbering pieces 1361 at both ends of the numbering strip 136 are connected, thus fixing the numbering strip 136 to the rotating rings 135.

[0043] Please see Figure 5 and Figure 7 In one embodiment, the outer peripheral wall of the rotating ring 135 is provided with a plurality of snap-fit ​​pieces 137 circumferentially equidistantly, and the first numbered piece 134 is provided with a plurality of snap holes 1341, the snap-fit ​​pieces 137 engaging with the snap holes 1341. In this embodiment, a snap hole 1341 is provided on each side of the first numbered piece 134. The structure of the snap-fit ​​piece 137 is not limited, such as a trapezoidal snap-fit ​​piece 137, where the outer end of the trapezoid is smaller than the inner end, and the more force is applied to the first numbered piece 134 during installation, the tighter the first numbered piece 134 engages with the snap-fit ​​piece 137.

[0044] Please see Figure 7 and Figure 8 In another embodiment, the snap-fit ​​member 137 includes a protrusion 1371 and a pressure plate 1372. The protrusion 1371 is fixed on the rotating ring 135, and its outer end is movably connected to the pressure plate 1372. When installing the first numbered piece 134, the protrusion 1371 and the pressure plate 1372 pass through the snap-fit ​​hole 1341, and then the pressure plate 1372 is rotated to press the pressure plate 1372 onto the first numbered piece 134, thereby fixing the first numbered piece 134.

[0045] Please see Figure 9 In one embodiment, the paint conduit 120 includes a first conduit 126 and a second conduit 127. The first conduit 126 is disposed within the support pipe 110. The second conduit 127 is detachably connected to the first conduit 126. A plurality of nozzles 121 are respectively connected to the first conduit 126.
