As shown in fig. 1 to fig. 5, the present embodiment provides a liquid storage box 1, a sealed chamber for storing an additive is provided inside the liquid storage box 1, the chamber inside the liquid storage box 1 in the present embodiment is an independently sealed liquid storage chamber, the liquid storage box 1 further has a conductive detection portion capable of detecting liquid level information of the internal additive, the conductive detection portion is formed as a part of the liquid storage box 1, and the liquid storage box 1 provided in the present embodiment has higher integrity, independent usability and reliability compared with the liquid storage boxes in the prior art.

The stock solution box 1 that this embodiment provided itself has the electrically conductive detection portion of the inside additive liquid level information of observable, has solved the problem that the assembly is complicated between current stock solution box 1 and the conductive probe 2, the poor additive of easily appearing of leakproofness is revealed and conductive probe 2 is taken out back stock solution box 1 and can not continue to use.

In one scheme, the conductive detection part and the liquid storage box 1 are of an integrated structure, the conductive detection part is integrally formed in the liquid storage box 1 through a specific machining process, and the conductive detection part and the liquid storage box 1 are of an integrated structure without being assembled and installed, so that the assembling steps are simplified. Meanwhile, the conductive detection part and the liquid storage box 1 are of an integrated structure, so that the problem of leakage of the additive due to poor sealing does not exist, and the reliability of the liquid storage box 1 is ensured.

Or, in another scheme, the conductive detection part is a partial structure of the liquid storage box 1, and the box body part of the liquid storage box 1 is made of a metal conductive material to form the conductive detection part. Make through the box body part with stock solution box 1 and form by metal conducting material electrically conductive detection portion, electrically conductive detection portion is the partly structure of stock solution box 1, improves the integrality of stock solution box 1.

Further, the conductive detection part is at least two conductive probes 2 integrally formed in the liquid storage box 1, and the conductive detection part is two conductive probes 2 in this embodiment for detailed description, but of course, the conductive detection part may also be three conductive probes 2, four conductive probes 2, and the like.

One end of the conductive probe 2 is a liquid level detection end 21 which extends into the additive of the liquid storage box 1 and is used for detecting liquid level, the liquid level detection end 21 can detect the liquid level information of the additive, the other end of the conductive probe 2 is provided with a conductive contact piece 22 which is in contact with and electrically connected with an external circuit, and when the liquid storage box 1 is placed into the putting device 4, the conductive contact piece 22 can be communicated with the external circuit.
