In one embodiment, the storage case 20 is drawably disposed within the detergent box 10; specifically, the detergent box assembly 1 further comprises a drawer box, wherein the detergent box 10 is fixedly installed with the washing machine, the drawer box is arranged in the detergent box 10 in a push-pull manner, the storage box 20 is installed on the drawer box to realize a drawing motion, when the drawer box is pulled out, the detergent can be added through an adding port 22 on the storage box 20, or the detergent box assembly 1 is cleaned to keep a clean washing environment, and when the drawer box is pushed in, the normal liquid outlet and washing of the washing machine can be realized. Wherein the drawer box is provided with at least one storage box 20 for storing laundry treatment agents including laundry detergent or softener or disinfectant. Preferably, the drawer box installation in this embodiment includes a laundry detergent storage box 20 and a softener storage box 20; when a plurality of storage cartridges 20 are provided, a plurality of sensors 30 are correspondingly provided to perform liquid level detection on each storage cartridge 20.

Further, when the storage case 20 is withdrawn and leaves the sensing range of the sensor 30, the washing machine stops operating. Specifically, when the drawer box is pulled out, the protruding structure 21 on the storage box 20 and the drawer box disappear together in the sensing range of the sensor 30, and if the liquid level signal is not present at this time, it is determined that the storage box 20 is not present, and the washing machine does not work; preferably, the information can be displayed on a washing machine interface or displayed on a mobile phone APP after being connected with a smart phone through a network and Bluetooth so as to achieve a prompting function.

In one embodiment, the sensor 30 is a photoelectric sensor, which determines whether there is liquid at the detection point based on the principles of optical reflection and refraction, so as to convert the liquid into a level signal for output, and further determine the liquid level of the storage box 20 for corresponding control; compared with a magnetic sensor, the photoelectric sensor does not need any mechanical contact surface, is not influenced by magnetism, heat energy and vibration, and has the advantages of simple structure, high positioning accuracy, high sensitivity, corrosion resistance, high temperature resistance and high pressure resistance, and small influence on a measured medium.

Further, as shown in fig. 2, in order to monitor the level of the detergent in the storage box 20, the sensor 30 includes at least two photo-emission points 31, wherein one photo-emission point 31 is used to form a highest level detection point 311, and one photo-emission point 31 is used to form a lowest level detection point 312.

Further, the sensor 30 further includes a plurality of photo-emission points 31 correspondingly forming a plurality of intermediate liquid level detection points 313, and the plurality of intermediate liquid level detection points 313 are sequentially arranged between the highest liquid level detection point 311 and the liquid level detection point in order to realize multi-level detection of the liquid level, thereby increasing the reliability of the operation of the detergent box assembly 1.

Further, the protruding structure 21 is a transparent structure for infrared light to pass through to realize detection. It should be understood that the protruding structures 21 may be transparent structures or may be made of materials through which infrared rays can pass.

In one embodiment, as shown in fig. 3 and 4, the protrusion 21 is located on the sidewall 201 of the storage box 20, and the protrusion 21 extends from the bottom 202 to the top 203 in the vertical direction to cover the lowest liquid level and the highest liquid level of the storage box 20, so as to facilitate the liquid level detection of the sensor 30.

In one embodiment, the sidewall 201 of the case 20 protrudes toward the inside of the case 20 to form the protrusion structure 21, and the protrusion structure 21 is polygonal. Preferably, the raised structures 21 are triangular in shape.

In an embodiment, the protruding structure 21 and the storage case 20 are integrally formed, i.e. the protruding structure 21 and the storage case 20 are formed by one-step injection molding, including common injection molding or blow molding, which simplifies the processing method and has good structural strength.
