[0041] For other structures not described, refer to Example 1.

[0042] Working principle: In the present invention, the material to be added is firstly put into the liquid storage tank 1 through the liquid inlet pipe 101, and then the temperature of the jacket outside the liquid storage tank 1 is controlled by the temperature regulator 200 to control the temperature of the added material inside the liquid storage tank 1.

[0043] When the dropwise material is stored in the liquid storage tank 1, the forward rotation mode of the output shaft of the driving motor 31 can be turned on, so that the driving motor 31 can drive the transmission shaft 3 to rotate in the forward direction, so that the secondary ratchet plate 2203 can drive the main shaft 2 to rotate, so that the stirring shaft 201 stirs the dropwise material in the liquid storage tank 1, so that the material contacts the inner wall of the liquid storage tank 1 more fully, and the temperature of the dropwise material is more accurately controlled by the outer jacket of the liquid storage tank 1;

[0044] During the rotation of the main shaft 2, the connecting frame 6 is driven to rotate, so that the driven gear 62 and the upper gear ring 1031 are meshed and matched, so that the driven gear 62 can drive the connecting frame 6 to rotate, so that the flip plate 611 can stir the dripping liquid material at the bottom of the inner cavity of the liquid storage tank 1, thereby increasing the fluidity of the dripping material, and synchronously cooperate with the liquid pushing plate 612 to scrape off the attachments on the bottom surface of the liquid storage tank 1, so as to avoid affecting the temperature contact transfer efficiency between the liquid material and the inner wall of the liquid storage tank 1;

[0045] After the liquid material for dripping inside the liquid storage tank 1 is used up, the reverse mode of the output shaft of the driving motor 31 can be turned on, and the main pawl disk 2201 can drive the second ratchet disk 23 to rotate, so that the active gear ring 4 and the spur gear 51 are meshed and matched, so that the spur gear 51 can drive the reciprocating screw 5 to rotate, so that the cleaning ring 52 acts on the inner wall of the liquid storage tank 1 to scrape off the attached impurities on the inner wall of the liquid storage tank 1, thereby cleaning the inner wall of the liquid storage tank 1 and avoiding the accumulation of attached impurities that reduces the efficiency of heat transfer, so that the external jacket of the liquid storage tank 1 can control the temperature of the liquid inside the liquid storage tank 1 more accurately and quickly.
