The sealing ring is made of soft felt, oil-proof rubber or nylon material.

When the air supply system passes through the first vent hole 120 and introduces air into the inner cavity 110, the slider 200 is pushed to move, so that the space of the fluorescent agent solution storage cavity 101 is reduced, and the fluorescent agent solution is conveyed into the fluorescent agent solution conveying pipe 300 through the first fluorescent agent solution conveying hole 310 and then is sprayed out of the spray head 600. In this process, the phosphor solution delivery tube 300 moves and rotates during the movement under the action of the screw thread of the outer wall of the phosphor solution delivery tube 300 and the first ball nut 102.

Thus, when the phosphor solution is filled in the phosphor solution storage chamber 101, the sealing member 400 seals the first phosphor solution feeding hole 310 by the first return spring 500. Thereby pushing the slider 200 in the direction of the first vent hole. Allowing the slider 200 to return to the home position.

The spray head 600 is installed at an end of the housing 100 away from the first vent hole 120 and is fixedly connected to the phosphor solution delivery pipe 300. Specifically, the head 600 is provided with a plurality of nozzle holes in its rotational direction.

In a schedule life, the lengths of the fluorescent tubes are various, and the moving distance of the shower head 600 is different for the fluorescent tubes with different lengths. Thus, in one embodiment, further comprising: a partition plate 700, and a second return spring 800.

This triggers the first sensor 104 when the slider 200 moves into abutment with the divider plate 700, thereby stopping inflation by the computer controlled air supply system. Similarly, when the slider 200 moves to be in contact with the second sensor 105, the second sensor 105 is triggered, so that the phosphor solution supply system is controlled by the controller to stop filling the phosphor solution.

This configuration helps control the formation of the slider 200.

When the slider 200 contacts the separation plate 700 to trigger the first sensor 104, the gas filling is stopped, and the sealing member 400 closes the first phosphor solution delivery hole 310 under the action of the first return spring 500.

Then, the phosphor solution supply system fills the phosphor solution into the phosphor solution storage chamber 101, thereby pushing the slider 200 to move, and when the slider 200 triggers the second sensor, the supply of the phosphor solution is stopped.

After that, the gas supply system fills the gas into the inner chamber 110 through the first vent hole 120, thereby opening the first phosphor solution delivery hole 310 and compressing the phosphor solution storage chamber 101, so that the phosphor solution enters the phosphor solution delivery pipe 300 through the first phosphor solution delivery hole 310 and is sprayed out through the head 600. In this process, the phosphor solution delivery tube 300 moves and rotates during the movement under the action of the screw thread of the outer wall of the phosphor solution delivery tube 300 and the first ball nut 102. Thereby uniformly spraying a layer of fluorescent agent solution on the inner wall of the lamp tube.
