The invention discloses a tapping switch of an on-load regulating transformer. The tapping switch comprises a single tapping switch controller connected with a voltage regulation controller, a first two-way switch with one end being connected with the single tapping switch controller and the other end being connected with the voltage regulation controller through a first filter, a second two-way switch with one end being connected with the single tapping switch controller and the other end being connected with the voltage regulation controller through the first filter and the first filter connected among the first two way switch, the second two-way switch and the voltage regulation controller, wherein, the first two-way switch and the second two-way switch are mutually connected, so as tobe used for controlling the change of the number of windings of the primary side or the secondary side of the voltage regulation controller along with the change of the switching condition of the first two-way switch and the second two-way switch. The tapping switch can realize the continuous and quick voltage regulation without harmonic waves, electric arcs and actuating mechanisms, and the tapping switch has few electronic switches, thereby having the advantages of simple structure, easy control and low cost.

Disclosed is a cooking and heating multipurpose furnace of a photovoltaic direct-current 60 V electric tricycle disaster relief motor home. In a heat-preservation round shell, a pot mounting frame is used for mounting of a pot, and therefore when the pot is used, a heating pipe cannot be damaged by compressing; the heating pipe and a reflection layer are arranged below a cooking kettle (or pot), the reflection layer is composed of two semicircular reflection layer bodies, one side is connected with a rotating shaft, and therefore the rotating shaft can rotate on a shell shaft hole below the heating pipe; a gap is formed in each semicircular reflection layer body, each semicircular reflection layer body is matched with a rotating rotary knob on a furnace shell, and the reflection layer bodies are fixed and hang down through the rotating rotary knobs; an air switch is used for controlling the heating pipe to be on and off, and is arranged on the lower half portion of the furnace; andwhen the multipurpose furnace is used for cooking and water boiling, the pot is used, and the two inner and outer heating pipes are on and off so as to control the temperature inside the furnace. According to the multipurpose furnace, the air switch is used for controlling on and off, arc discharging is avoided, the furnace achieves multiple purposes of cooking, water boiling and heating, and occupation is saved; and the furnace is suitable for being used by a 60 V electric tricycle motor home and a 60 V electric motor home.
