[0025] The drive adjusting assembly 6 comprises a bidirectional screw 602, which is rotatably arranged inside an evaporation chamber and below the L-shaped pipeline 5.
[0026] Among them; the L-shaped pipeline 5 is provided with a connecting head 502 at the tail end, the L-shaped pipeline 5 is connected with a hose 503 through the connecting head 502, one end of the hose 503 away from the connecting head 502 penetrates through the side wall of the evaporation chamber and is connected with a liquid supply equipment outside, by being provided with the connecting head 502, the liquid inlet of the L-shaped pipeline 5 is connected with the hose 503, so that the liquid supply equipment outside can deliver liquid to the L-shaped pipeline 5 through the hose 503, and finally discharge through the drip head 501.
[0027] Among them; the support frame 2 is provided with a shaft hole 201 in the center of the upper wall, the mounting block 3 is provided with a limiting shaft 4 at the lower end surface, and the mounting block 3 is rotatably connected with the support frame 2 through the limiting shaft 4, by being provided with the mounting block 3 and the limiting shaft 4, the L-shaped pipeline 5 can be effectively limited and supported, so that the L-shaped pipeline 5 can rotate.
[0028] The driving adjusting assembly 6 further comprises a driving motor 601, a limiting seat 603 and a driving block 604. The limiting seat 603 is arranged at one end of the bidirectional screw rod 602.

The threads arranged at the two ends of the bidirectional screw rod 602 are opposite in direction. The driving block 604 is provided with two driving blocks 604, which are threadedly connected with the bidirectional screw rod 602. The evaporation boat body 1 is fixed in the evaporation chamber. Through the working of the driving motor 601, the bidirectional screw rod 602 can be effectively driven to rotate. Under the limiting action of the L-shaped pipeline 5, the two driving blocks 604 move along the bidirectional screw rod 602 to approach or move away from each other.
