The invention relates to an intelligent liquid adding seal which comprises a shell, a
liquid storage cavity, an adjusting device and a seal body, wherein the seal body comprises a base, an
engraving plate and an elastic
resorption cavity; drainage tubules are arranged in the
engraving plate; the elastic
resorption cavity communicates with the
liquid storage cavity through a flow
guide tube; an elastic suction ball is connected to the flow
guide tube in series; an
extrusion block is arranged at the position, directly facing the elastic suction ball, in the shell, and the transmission end of the
extrusion block and the driving end of a driving block are magnetically attracted; the elastic suction ball, the driving block, the
extrusion block, a limiting bracket and a reset spring jointly form the adjusting device; during
stamping, the shell is pressed down, a proper amount of liquid is extracted from the
liquid storage cavity through the adjusting device, and injected into the seal body; and after the liquid is drained to the contact face between the seal body and a file, the
stamping is completed. According to the intelligent liquid adding seal, a unique intelligent liquid adding structure is adopted, and the using method of a user is improved; it is effectively guaranteed that the seal is clear and complete, and red ink paste is effectively prevented from remaining or contaminating other clothes.
