摘要： A blowtorch includes a casing and a control unit. The control unit includes an activate button and a lock button. The lock button is switchable between a first lock position and an intermediate position, or between the intermediate position and a second lock position. The activate button is switchable between a standby position and an activation position when the lock button is in the intermediate position. The lock button contacts the activate button and restricts the activate button to hold in the activation position when the activate button is in the activation position and the lock button is in the first lock position or the second lock position.

摘要： A combustion device includes a stove body and a flow guiding device. The stove body has first and second sides disposed oppositely and includes a wick disposed between the first and second sides. The wick is spaced from the first and second sides at first and second distances respectively. A flow guiding device includes first and second shielding members respectively connected to the first and second sides of the stove body. The wick is spaced from the first and second shielding members at third and fourth distances respectively. The third distance is greater than the first distance and the first shielding member is spaced from the first side. The fourth distance is greater than the second distance and the second shielding member is spaced from the second outer side.

摘要： A combustion device includes a candle wick and a flow guiding assembly. The flow guiding assembly includes a support, a plurality of guide vanes secured to the support, a first shield member fixed at a side of the support, and a second shield member pivotally connected to the first shield member. The second shield member is pivotable in relation to the first shield member between a closed position and an open position to selectively form a gap. The plurality of guide vanes is disposed between the first and second shield members. The candle wick is disposed between the plurality of guide vanes. Therefore, the combustion device is easy to use by the above structure.
