[0012] Through the technical scheme, the vent can be opened by rotating the sealing plate, so that the liquid reagent can flow freely.

[0013] As a further improvement of the above scheme, a limiting ring is fixedly installed on one side of the sealing cover, and a limiting groove matched with the sealing plate is formed in an inner ring surface of the limiting ring.

[0014] Through the technical scheme, the sealing plate is always tightly attached to the sealing cover when the limiting ring presses the sealing plate, so that the sealing effect is prevented from disappearing.

[0015] As a further improvement of the above scheme, a limiting ball is fixedly arranged on the droplet pipe, a communication column for opening and closing the droplet pipe is arranged on one side of the limiting ball, one end of the communication column penetrates through the limiting ball and the droplet pipe, a flow-through opening is formed in one side of the communication column, and a rotating block is fixedly installed at the other end of the communication column.

[0016] Through the technical scheme, the droplet pipe can be opened or closed by rotating the communication column, so that the liquid reagent in the telescopic pipe can be conveniently supplemented.

[0017] Compared with the prior art, the utility model has the beneficial effects that:

[0018] The utility model discloses a release assembly, a cover assembly and a communication column, when liquid reagent needs to be quickly released, the cover assembly seals the release assembly, rotates the connecting column and extrudes the release assembly, so that the liquid reagent in the inside can be quickly extruded and released, opening the cover assembly and not extruding the release assembly can make the liquid reagent flow out, which can quickly extrude and release the liquid that needs to be quickly released, and can naturally discharge and release the liquid that does not need to be quickly released, and is suitable for adding various different liquid reagents.
