LIQUID GUIDE INSERTION STRUCTURE, ADDITIVE FEEDING MODULE AND LAUNDRY TREATMENT APPARATUS

A liquid-conducting plug structure, provided on an additive delivery module, which can be inserted into the liquid storage box (1) by a drop port of the liquid storage box (1) to be connected to the additives inside the liquid storage box (1), the liquid-conducting plug structure being provided with a detection device for detecting the category and/or the residual amount of the additives inside the liquid storage box (1). There is also provided an additive delivery module comprising a closed chamber liquid storage box (1) with an internal storage for additives, and an insertion groove for mounting the liquid storage box (1), the insertion groove being provided with the liquid-conducting plug structure. There is also provided a clothing treatment device with the additive delivery module between the clothing treatment device and a tap water connector. Based on the above setup, the category and/or residual amount of additives in the liquid storage box (1) is detected by the detecting device, in order to realize the effect of accurate detection of the category and/or residual amount of additives in the liquid storage box (1).
