[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0024] Please refer to Figures 1-4 A quick-release nozzle is installed on a vertical device, and the quick-release nozzle comprises a spray head 10 and a mounting seat 20, and the mounting seat 20 is installed on a vertically arranged spray pipe. A plurality of mounting seats 20 and spray heads 10 are installed on the spray pipe, and the spray pipe is connected with a liquid storage tank, which can store liquid medicine or clean water according to the use requirement.

[0025] The spray head 10 is hollow inside, the top end of the spray head 10 is provided with a spray opening 30, and the outer periphery of the spray head 10 is provided with at least one retaining edge 40, and the top end of the retaining edge 40 is provided with a recess 50. Liquid can be sprayed onto the vertically conveyed PCB board through the spray opening 30 at the top end of the spray head 10. It should be understood that the spraying power of the spray head 10 comes from the water pump, which can deliver the liquid inside the liquid storage tank into the spray pipe and then spray it out of the spray opening 30. When it is necessary to remove the film, develop and etch, the liquid medicine is stored in the liquid storage tank, and the liquid medicine is sprayed onto the PCB board through the spray opening 30. A plurality of spray heads 10 spray the PCB board, and the liquid medicine can be evenly attached to the PCB board. When it is necessary to clean the circuit board after removing the film, developing and etching, clean water is stored in the liquid storage tank, and the clean water is sprayed onto the PCB board through the spray opening 30 to obtain a clean circuit board.

[0026] At least one limiting block 60 is arranged on the mounting seat 20, which is used to limit the spray head 10 after installation. A bayonet 70 is defined between the limiting block 60 and the mounting seat 20. When it is necessary to install the spray head 10 on the mounting seat 20, the spray head 10 is placed on the mounting seat 20, and then the spray head 10 is rotated so that the retaining edge 40 can enter the bayonet 70. The end of the limiting block 60 towards the mounting seat 20 is provided with a protrusion 80. When the spray head 10 is rotated to the set position, the protrusion 80 can be attached to the recess 50. The limiting block 60 limits the spray head 10 in the vertical direction, and the protrusion 80 limits the spray head 10 in the horizontal direction, so that the spray head 10 can be tightly installed on the mounting seat 20, achieving a good sealing effect. The spray head 10 and the mounting seat 20 are connected, and when liquid is sprayed, the liquid can be prevented from being sprayed out of the connection between the spray head 10 and the mounting seat 20. When it is necessary to disassemble the spray head 10, only the spray head 10 needs to be rotated so that the protrusion 80 is separated from the recess 50, and then the spray head 10 can be removed from the mounting seat 20.

[0027] In an embodiment, two stop edges 40 are symmetrically arranged opposite the nozzle 10; two limit blocks 60 are symmetrically arranged opposite the mounting seat 20, the cross section of the limit block 60 is in inverted L shape, that is, the limit block 60 comprises a side plate and a top plate, the protrusion 80 is arranged on the bottom surface of the top plate, the protrusion 80 is arc surface protrusion 80, and the recess 50 is arc surface. Thus, when disassembling, the protrusion 80 can be separated from the recess 50 by slightly applying force, that is, the disassembly of the nozzle 10 and the mounting seat 20 is facilitated.

[0028] Further, a stop block 90 is arranged at the top end of the stop edge 40, the stop block 90 is located on one side of the recess 50, and the height of the stop block 90 is higher than the height of the bayonet 70. The stop block 90 limits the rotation of the nozzle 10 on the mounting seat 20, and the stop block 90 can abut against the end of the limit block 60 to limit the rotation of the nozzle 10.

[0029] Further, a slope 100 is arranged at the end of the stop edge 40 away from the stop block 90, and the slope 100 is inclined upward in the direction of the stop block 90. When the nozzle 10 is installed, the end of the stop edge 40 with the slope 100 enters the bayonet 70 first, the contact area between the stop edge 40 and the limit block 60 gradually increases, facilitating the installation of the nozzle 10; when the nozzle 10 is disassembled, the end of the stop edge 40 with the slope 100 comes out of the bayonet 70, and the contact area between the stop edge 40 and the limit block 60 gradually decreases, thus facilitating the disassembly of the nozzle 10.

[0030] In an embodiment, a baffle 110 is arranged on the side of the nozzle 10, two baffles 110 are symmetrically arranged opposite the nozzle 10, and the baffle 110 separates the two stop edges 40. The baffle 110 mainly plays a role of force support here, when the nozzle 10 needs to be disassembled, the hands of a person directly apply force on the baffle 110, so that the rotation of the nozzle 10 is facilitated.

[0031] In an embodiment, a spraying table 120 is arranged at the top end of the nozzle 10, the spraying table 120 is a boss, the nozzle 30 is arranged at the center of the boss, and the cross section of the nozzle 30 is in V shape. Thus, the liquid sprayed from the nozzle 30 can be fan-shaped on the PCB board, so that the liquid spraying effect on the PCB board is more uniform, and the effect on the PCB board is better.

[0032] In order to facilitate the positioning of the nozzle 10, a limit protrusion 130 is arranged at the center of the mounting seat 20, and the nozzle 10 is sleeved with the limit protrusion 130. When installing, the inner bottom edge of the nozzle 10 can abut against the limit protrusion 130, and the limit protrusion 130 plays a role of positioning and limiting here.

[0033] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
