Abstract: A compact gas range has a gas storage slot formed between an upper circular cover and a lower circular seat. The gas storage slot is divided by two partitions into three chambers. The two partitions are provided with a valve piece having a valve hole and a filtration core disposed in the valve hole. When the ignition switch is turned on, the liquid form gas is allowed to enter the first chamber. The liquid form gas is then filtered and transformed into a gas form gas which enters the second chamber via the valve hole of the second partition. The gas form gas is completely vaporized in the third chamber so as to bring about a complete combustion. The lower circular seat is provided with a gas replenishing hole and a tube which is provided therein with a ring and a guide having a hole. The ring is capable of urging the joint of a gas can to avert the gas leak.
