BACKGROUND The existing multi-functional water outlet devices, such as a shower and a top sprayer, are usually provided with a plurality of water outlet modes, and the existing water outlet modes are switched by means of mechanical structure toggle or electronic control. The mechanical structure switching method requires a specific structure, and the design of the appearance of the shower and top sprayer or the user's operating experience will be limited by the mechanical structure, which is not suitable for the needs of bathroom spaces with more diverse design styles. If the electronic control switching method is adopted, due to the usage scenarios of the shower and the top sprayer, direct charging is impossible, and generally self-generation is required to operate the solenoid valve that controls and switches the water outlet mode. Through electronic control, when the shower or top sprayer is just supplied with water and starts working, the water pressure is not enough, resulting in limited power that can be provided. Generally, it can only satisfy the operation of one solenoid valve.
