[0029] The pressing mechanism 3 comprises a movable seat 3-1, a push rod 3-2, a driving cylinder 3-9 and a mounting frame 3-12. The movable seat 3-1 is slidingly mounted on the mounting frame 3-12, so that the movable seat 3-1 is arranged above the fixed seat 2 in a liftable manner. The mounting frame 3-12 provides a guide for the lifting of the movable seat 3-1. An installation cavity 3-3 is arranged in the movable seat 3-1, and the installation cavity 3-3 is used for fixing the nozzle head 1-1. The push rod 3-2 is slidingly mounted in the installation cavity 3-3. The push rod 3-2 is used for ejecting the nozzle head 1-1 from the installation cavity 3-3, so that the nozzle head 1-1 is pressed on the nozzle body 1-2. The driving cylinder 3-9 is fixedly mounted on the mounting frame 3-12, and the push rod 3-2 is connected with a cylinder shaft of the driving cylinder 3-9 through screw threads. The driving cylinder 3-9 is used for driving the push rod 3-2 to lift.

[0030] An air extraction channel 4 is arranged through the push rod 3-2. A connecting channel 3-10 is arranged on the cylinder shaft of the driving cylinder 3-9. One end of the connecting channel 3-10 is communicated with the air extraction channel 4, and the other end of the connecting channel 3-10 is connected with an air extraction pipe 3-11. The air extraction pipe 3-11 is connected with an external negative pressure device, and the air extraction channel 4 is extracted by the negative pressure device.

[0031] The push rod 3-2 comprises a limiting section 3-4 and a connecting section 3-5. The limiting section 3-4 is abutted with the nozzle head 1-1. An outer thread is arranged on the top outer side wall of the connecting section 3-5, so that the connecting section 3-5 is connected with the driving cylinder 3-9 through screw threads. A two-section stepped hole is arranged in the movable seat 3-1, and the push rod 3-2 is slidingly mounted in the stepped hole.

[0032] In the embodiment, the nozzle head 1-1 is fixed in the installation cavity 3-3.

[0037] (2) The driving cylinder 3-9 is driven to work, and the movable seat 3-1 and the push rod 3-2 are simultaneously moved downward under the action of the spring 3-8.

[0038] (3) When the movable seat 3-1 abuts against the fixed seat 2, the movable seat 3-1 stops moving, and the push rod 3-2 continues to move downward under the action of the driving cylinder 3-9. Under the action of the push rod 3-2, the nozzle head 1-1 moves downward and abuts against the nozzle body 1-2. With further movement of the push rod 3-2, the nozzle head 1-1 is press-fit on the nozzle body 1-2.

[0039] (4) The cavity formed by the installation cavity 3-3 and the upper end face of the nozzle body 1-2 is in a negative pressure state through negative pressure of the negative pressure channel 4, so that the spray nozzle 1 is lifted.
