The liquid blanking module of the second embodiment is different from the liquid blanking module of the first embodiment in a specific structure in the liquid blanking module, and specifically, as shown in fig. 8 to 17, in the second embodiment, the liquid blanking module includes a first magnetic conductive structure 26, the first magnetic conductive structure 26 is engaged with the discharging pipe 212 so as to be capable of moving synchronously with the discharging pipe 212 in a predetermined direction, and when the electromagnetic opening and closing device 13 is powered, the electromagnetic opening and closing device 13 drives the first magnetic conductive structure 26 to move in the predetermined direction, so that the discharging port 213 of the discharging pipe 212 extends into the discharging pipe 12, so that the discharging pipe 212 is communicated with the discharging pipe 12. Specifically, the first magnetic conductive structure 26 has a first position magnetically engaged with the electromagnetic opening/closing device 13 and a second position away from the electromagnetic opening/closing device 13. When blanking is needed, the electromagnetic opening and closing device 13 is powered on, a magnetic field is generated between the first magnetic conduction structure 26 and the electromagnetic opening and closing device 13, and the first magnetic conduction structure 26 moves to the first position under the action of the magnetic field force. During the movement of the first magnetically conductive structure 26 to the first position, the first magnetically conductive structure 26 cooperates with the discharge pipe 212 to move the discharge pipe 212 towards the feed pipe 12. When the first magnetic conductive structure 26 moves to the first position, the discharge hole 213 of the discharge pipe 212 extends into the feeding pipe 12, so as to communicate the discharge pipe 212 with the feeding pipe 12. When the discharging is not needed, the electromagnetic opening and closing device 13 is powered off, the magnetic field force between the first magnetic conduction structure 26 and the electromagnetic opening and closing device 13 disappears, the first magnetic conduction structure 26 can move to the second position, and in the process that the first magnetic conduction structure 26 moves to the second position, the discharging hole 213 of the discharging pipe 212 moves out of the discharging pipe 12, so that the discharging pipe 212 is disconnected from the discharging pipe 12. The structure is simple, easy to realize and low in cost.

As shown in fig. 10, 11, 15, and 16, in the second embodiment, the liquid discharging module includes a base 22, the first magnetic structure 26 is a magnetic conductive sheet, and a second elastic structure 27 is disposed between the magnetic conductive sheet and the base 22, so that when the electromagnetic opening/closing device 13 is powered off, the magnetic conductive sheet can drive the discharging opening 213 of the discharging pipe 212 to draw out the discharging pipe 12 under the elastic restoring force of the second elastic structure 27. Specifically, when blanking is required, the electromagnetic opening and closing device 13 is energized, the first magnetic conductive structure 26 moves to the first position under the action of the magnetic force, and the second elastic structure 27 is compressed. When the discharging is not needed, the electromagnetic opening and closing device 13 is powered off, the magnetic field force between the first magnetic conduction structure 26 and the electromagnetic opening and closing device 13 disappears, the first magnetic conduction structure 26 moves to the second position under the action of the elastic restoring force of the second elastic structure 27, and in the process that the first magnetic conduction structure 26 moves to the second position, the discharging port 213 of the discharging pipe 212 moves out of the discharging pipe 12, so that the discharging pipe 212 is disconnected from the discharging pipe 12. The structure is simple, the first magnetic conduction structure 26 does not need to be reset manually by a user, operation steps are reduced, and the use experience of the user is improved.

Because the electromagnetic opening and closing device 13 and the first magnetic conduction structure 26 are respectively located outside and inside the base 22, a magnetic gap is generated between the electromagnetic opening and closing device 13 and the first magnetic conduction structure 26, and the existence of the magnetic gap will affect the magnetic attraction between the electromagnetic opening and closing device 13 and the first magnetic conduction structure 26, so that the magnetic attraction is reduced. In order to ensure that the magnetic attraction force between the electromagnetic opening and closing device 13 and the first magnetic conductive structure 26 is within a predetermined range, the volume of the electromagnetic opening and closing device 13 is generally increased, but the above structure is not favorable for the miniaturization design of the liquid blanking module. In order to solve the above problem, in the second embodiment, the second magnetic conductive structure 80 is additionally provided, the second magnetic conductive structure 80 is inserted into the base 22 and attached to the electromagnetic opening/closing device 13 to reduce the size of the magnetic gap, and it is not necessary to increase the volume of the electromagnetic opening/closing device 13 to ensure the magnetic attraction between the electromagnetic opening/closing device 13 and the first magnetic conductive structure 26, thereby realizing the miniaturization design of the liquid blanking module.

As shown in fig. 9, 10, 13 and 17, in the second embodiment, the second magnetic structure 80 is a magnetic block, and when the electromagnetic opening/closing device 13 is powered off, the distance L between the magnetic block and the first magnetic structure 26 is between 3mm and 8mm, and when the electromagnetic opening/closing device 13 is powered on, the magnetic block is attracted to the first magnetic structure 26. If the distance L is less than 3mm, the moving stroke of the discharging pipe 212 is affected, so that the discharging port 213 cannot extend into the discharging pipe 12; and if distance L is less than 8mm, then need increase electromagnetism switching device 13's volume thereby increase magnetic attraction, this will lead to the volume of liquid unloading module great, is unfavorable for miniaturized design.

Specifically, after the installation is completed, the connecting cap 218 abuts against the discharging pipe 12 and keeps relatively still with the discharging pipe 12, after the electromagnetic opening and closing device 13 is powered on, the first magnetic conduction structure 26 drives the pipe body 217 to move, so that the end portion of the pipe body 217 extends into the discharging pipe 12, and at this time, the discharging pipe 212 is communicated with the discharging pipe 12 through the discharging hole 213. After the electromagnetic opening and closing device 13 is powered off, the first magnetic conductive structure 26 drives the tube body 217 to move, so that the end portion of the tube body 217 moves out of the blanking tube 12, and the connecting cap 218 blocks the discharge hole 213, so that the discharge tube 212 is not communicated with the blanking tube 12. When the discharge pipe 212 is replaced, the connection cap 218 is always in the blocking position, so that no leakage phenomenon of the discharge port 213 occurs, and the cleanness of the batching device is ensured.
