Toilet plunger

A toilet plunger that is used to unclog a drain of a toilet by removing impurities, the toilet plunger comprising:

• a gas container containing a predetermined amount of gas therein, with an opening thereof closed by a closing plate;
• a body having defined therein a passage extending in a lengthwise direction to allow the gas to pass through and a gas container-receiving portion depressed to a predetermined depth from an upper end thereof to closely receive an opening side of the gas container;
• a puncture pin disposed in a central portion of the gas container-receiving portion to puncture the closing plate so that the gas that is contained in the gas container is discharged toward the passage;
• a cover having an inner space capable of receiving a portion of the gas container opposite the opening, wherein the cover is screw-coupled to an upper portion of the body to cover the upper portion of the body that is open, such that the container is moved toward the puncture pin according to a screw motion when a user rotates the cover;
• and
• an insert connected to a lower end of the body to guide the gas that is discharged from the gas container along the passage toward the drain,
• wherein the body has a pair of partitions therein, the partitions being spaced apart from each other at a predetermined interval, thereby forming a puncture pin-receiving portion, into which the puncture pin is disposed, and dividing the gas container-receiving portion and the passage from each other, and
• wherein each of the partitions has a safety passage therein, the safety passage being formed around the puncture pin-receiving portion to connect the gas container-receiving portion to the passage in order to adjust pressure in the gas container-receiving portion.
