Abstract: A thermostat module, applied in an airflow device, includes a main body and at least one energy storage component, and the main body has a containing space and a first air vent and a second air vent communicated with the containing space, and the airflow device is configured corresponding to the first air vent. The energy storage component includes a fixing element and at least one energy storage element, and the fixing element is detachably coupled to a frame, so that the energy storage component is accommodated in the containing space. The quantity of energy storage components can be increased or decreased by assembling, so that the thermostat module has the effect of adjusting the quantity of energy storage elements conveniently.
