Description

Technical Field

[0001] The utility model relates to the technical field of public washing machines, and more specifically to a self-service laundry liquid adder and a public washing machine. Background Art

[0002] At present, domestic self-service washing machines require users to bring their own washing powder or laundry liquid when using them. The washing powder or laundry liquid is placed randomly after use, making it difficult to control the overall hygiene of the laundry room, and excessive use affects the life of the machine; improper use of detergents by users will cause detergents to spill into the laundry room, which is difficult to clean and time-consuming and laborious to clean; improper use of their own laundry liquid will cause the laundry liquid to leak into the machine body. In public scenes, hygiene issues are very important, and a dirty and messy environment can easily affect the user experience. Therefore, some manufacturers have set up automatic laundry detergent adding devices, such as the Chinese patent application number CN202111066992.4, which discloses a liquid adding and replenishing system and implementation method for public washing machines, which relates to the field of public washing machines, including a cloud server, the cloud server is connected to an operation screen through a signal, a signal recognition module is provided in the operation screen, the signal recognition module is connected to a signal transmission module through a signal, the signal transmission module is connected to a liquid pump box through a serial port line, and the serial port line contains output and input signals, the liquid pump box is connected to a washing machine, the liquid pump box is connected to a flow reminder module and a flow meter data reading module, the flow reminder module is connected to the operation screen through a serial port signal, the cloud server is provided with a consumption statistics module and a liquid supply prediction module, and the liquid pump box is connected to a replenishing component.
