A device and a method for preparing solution, and an equipment for preparing a scented tea are provided. The device includes: a steam generator (1), a valve unit with double inlets, an air pump (22), a material chamber (12), and a fluid container (19). A steam outlet of the steam generator (1) is connected to one inlet of the valve unit with double inlets by a pipe, and the other inlet of the valve unit with double inlets is connected to the air pump (22), and an outlet of the valve unit with double inlets is connected to the material chamber (12). Materials for preparing solution are deposited in the material chamber (12), and the material chamber (12) has an outlet extending into the space under the liquid level of the fluid container (19) by a pipe. The solution may be extracted adequately without scalding the user, and the volatilization of volatile effective components in the fluid container is also further lowered.
