Abstract: A smart home scene switching method and system are disclosed. In the method and system, a priority order of several scenes is calculated dynamically according to status parameters of a current scene and/or historical record of past scenes, and scenes are sequentially switched according to the priority order, based on an event causing scene change and a switching rule between the event and the scene. The smart home scene switching method and system expand switching and selecting of smart home scenes. The scenes are switched according to the priority order, thus simplifying user's switching and selecting operation on scenes and further improving the efficiency of switching scenes, which improves the reliability and stability of smart home scene switching.

Abstract: An automatic dosing device is disclosed which comprises a frame on which are disposed a flavoring unit, a flavoring receiving unit and a control unit. The flavoring unit comprises a solid flavoring mechanism and a liquid flavoring mechanism, the solid flavoring mechanism comprising a solid flavoring module and a first drive device, the solid flavoring module being detachably connected to the first drive device, the liquid flavoring mechanism comprising a liquid flavoring module and a second drive device, the liquid flavoring module being detachably connected to the second drive device. Both the first and second drive devices are fixed on the frame and are connected with the control unit, respectively; the flavoring receiving unit receives flavorings from the solid flavoring mechanism and the liquid flavoring mechanism.
