The main switch and the auxiliary switch can be used to smoothly introduce the gas into the auxiliary tank for the heart as a fire source, and the pressure switch can be used to safely block the excessive gas pressure. To prevent gas explosions.

The invention is further designed according to the existing gas-fired gas stove assembly, so that the furnace can be used as a fire power supply to pass through the pressure limiting switch disposed therebetween to avoid the gas pressure filled inside. If it is too large, it will be turned on by mistake, and the gas switch can be restricted by a safety switch before it is turned on, and the accident caused by the child rotating the gas switch by mistake can be prevented.

The first main object of the present invention is to construct a pressure limiting switch, a safety switch, a liquid gas interceptor and a voltage regulator between the upper and lower furnace bodies of the inflatable stove; wherein the pressure limiting switch The pressure-limiting switch includes a connecting outer tube formed with a first and a second through hole formed therein, and a connecting outer tube is formed on the side of the upper furnace body which is adjacent to the gas filling B groove. The first through hole can be placed into a set of spring-loaded pushing members, and the outer end of the pushing member is concavely provided with a truncated ring groove, and the other step along the pushing piece is in each ring groove.
