Insect-destroying device

An insect-destroying device, comprising:

• at least one of salt pellets or sand grains;
• a gun body with a shape of a pistol, having an exit port configured to propel the at least one of salt pellets or sand grains in a propelling direction for killing a target insect, the gun body comprising:
• an elongated tube barrel, at least partly received in an inner space of the gun body, and an end of the elongated tube barrel connected to the exit port;
• a first through-hole being defined in the elongated tube barrel and configured to communicate with the exit port;
• an insecticide storing housing, wherein the insecticide storing housing is disposed at a top side of the elongated tube barrel and is configured to store the at least one of salt pellets or sand grains, a second through-hole is defined in an end of the insecticide storing housing which is adjacent to the elongated tube barrel;
• an extending portion extending from the insecticide storing housing to cover the first through-hole;
• and,
• a spacer sheet protruding and extending from a top surface of the elongated tube barrel toward the extending portion and at least partly overlapping with the extending portion, and a receiving space being defined between the top surface of the elongated tube barrel and the spacer sheet;
• wherein the insect-destroying device is capable of operating in a loaded state-, in which the second through-hole is shifted to face towards the first through-hole so that the at least one of salt pellets or sand grains stored in the insecticide storing housing enter into the elongated tube barrel via the second through-hole and the first through-hole, and an unloaded state, in which the first through-hole is isolated from the second through-hole, so that the at least one of salt pellets or sand grains stored in the insecticide storing housing are not allowed to enter into the elongated tube barrel;
• in the unloaded state, the extending portion is partly received in the receiving space, and both the extending portion and the spacer sheet cover the first through-hole, so that the second through-hole is isolated from the first through-hole;
• in the loaded state, the extending portion moves toward to an end of the gun body far away from the exit port and then is fully received in the receiving space, so that the second through-hole, the first through-hole, and the exit port are in air communication with each other.
