A touch battery has a short contact member, an insulating ring, an intermediate threaded connector, a PCBA control panel, a touch member, a tail membrane, a battery pole having a battery provided therein, and a tobacco rod. The battery supplies input power for the PCBA control panel. The PCBA control panel is electrically connected to the short contact member and the touch member, respectively. The battery pole is disposed in the tobacco rod. The tobacco rod is connected to the short contact member via the intermediate threaded connector. The short contact member is disposed inside the intermediate threaded connector via the insulating ring. The tail membrane is connected to the touch member. The battery is allowed to output normally in a constant-voltage touch manner, so that the conventional manual output with keys is avoided, and the demands of consumers for multiple selections are met.
