description The utility model discloses a high-sensitivity smoke alarm for forest fire prevention, and the alarm comprises an air inlet cabin, a fan, an air guide cabin, and a smoke alarm sensor. The air inlet cabin is disposed at an air inlet of the fan. One end of the air guide cabin is disposed at an air outlet of the fan. The smoke alarm is disposed at the other end of the air guide cabin. The housing of the air guide cabin is provided with vent holes. Compared with the prior art, the alarm employs the fan to draw in air and directly transmits the air to the smoke alarm sensor. The alarm can effectively improve the sensitivity of smoke alarm, thereby preventing forest fire from happening or timely inhibiting the fire. In addition, the employed smoke alarm sensor is simple in circuit structure, is low in cost, and has the values of popularization and application.
